Modern Risk Analysis Based on PRA - Essay Example This risk assessment leads to an output of ranging risks prior to the experiences of the receptors. Proper probabilistic risk assessments require adequate description of the input parameters. For this to happen, it requires that distributional data be available and further be adequate in describing the already identified input parameters. PRA purely employs probability and probability distributions in the characteristic analysis. Probability denotes the chances of occurrence of an uncertain phenomenon. The uncertainty constitutes occurrence of risk. Through PRA, risk assessments can be carried out and the levels of risk therein identified. Use of probability in the assessments of risk can be used in the understanding, quantifying and management of risk. Such a process can further be analysed in relation to the limitations of quantifying risk using probability. Reasons why probability is chosen as opposed to other measures of uncertainty Probability quantifies the description of level s of risk, characterized by the aspect of uncertainty or variability associated with risk estimates. Risk therefore becomes comprehensively characterized by using probability, which would not be the case when point estimate measure of risk is used (UKOOA, 2006, pg. 134). This feature therefore makes probability a better measure of risk than the point estimate method. Quantitative analysis of risk allows for diverse treatment of uncertainty variables used in the determination of underlying risks prior to the probability of occurrence of the identified risks. Risk management requires the use of flexible tools of analysis as well as availability of vast information in regard to what is being accounted for. In this regard, probability becomes the best measure of uncertainty. Uncertainty constitutes risks, and it is the risks that risk managers ought to address. Probability allows for flexibility in the analysis and treatment of variables in the probability equation (U.S. Environmental P rotection Agency, 2005, pg. 78-79). Following this, a large volume of information can be derived, thereby allowing risk managers to make choices among alternatives. Other measures of uncertainty do not provide for flexibility and variant information, making risk managers fixed to the choices they make or to the scope that they can manage risks using such measures as a baseline. Managers need to assess and evaluate high-end risks, and the best gateway to succeeding in that is using probability in measuring levels of risk. Limitations of quantitative approach to risk The quantitative approach to risk is time consuming. It is procedural and treatment and analysis of variables require adequate time. Step by step consideration of variables is necessary in order to ensure that each and every aspect that constitutes risks is identified and accounted for (Stern and Fineberg, 1996, pg. 157). This process is characterized by huge requirement of resources. Adequate resources need to be pulled into place. Finances are required at every step of the quantification process. Gathering data and information is expensive. The management should be aware of these requirements before such an approach to risk is adopted. In order to come to a critical and fundamental understanding of the risks through the quantification approach all required information should first be in place. Data collection, cleaning, editing, analysis and reporting require that enough resources be allocated for the purposes.

Usage of Magic and Supernatural Elements in Childrens Literature Research Paper

Usage of Magic and Supernatural Elements in Childrens Literature - Research Paper Example Women began to slowly make their voices heard as an oppressed gender and philosophers were beginning to gain a greater understanding of the workings of the human mind. The child, often considered either a sinful and wild creature or a miniature adult, was beginning to be recognized as something still developing. There was a â€Å"veritable explosion of information about this period of physiological and cognitive development in human beings† and literature became â€Å"a central vehicle for expressing ideas about the self and its history† (Steedman 5). Although perhaps initially introduced as a means of breaking with the strict moralistic attitudes of the past, the use of magic and the world of the supernatural proved effective in teaching children in a way they could understand. Breaking from the ‘normal’ world with the introduction of the supernatural or the magical realm makes it possible for authors to personify various behaviors, values and character traits and thus give children more accessible avenues to complex concepts in keeping with their varying levels of understanding. Cognitive ability begins with birth, but improves upon skills acquired during the preschool years to apply to things outside of the self. There are four main categories of skills developed during this period (Santrock 1997). The first of these are self help skills in which the child learns to take care of their everyday needs such as dressing themselves. They also learn social help skills in which they begin to perceive the importance of helping others through activities such as household chores and demonstrating their ability to think outside of themselves. School skills are introduced in which the child learns the academic tools necessary for success in that arena, particularly in developing the analytical skills necessary for logic and mathematics. The final main category is play skills, in which the child

Anti Jerk Control Of Hybrid Electric Vehicles Engineering Essay

Anti Jerk Control Of Hybrid Electric Vehicles Engineering Essay This interim report consists of three chapters explaining the initial study and research into anti jerk control of hybrid electric vehicles. This project aims at electrification of anti-jerk control in hybrid vehicles by using the hybrid vehicle electric motor to damp these oscillations and to analyze its effect on fuel consumption, comfort and sportiness of the vehicle and then to compare the results with fuelling only method. This project will also include studying the impact of passive damping with DMF in these vehicles. As a part of this project, a model of a hybrid diesel engine driveline with DMF will be developed using Simulation X and an active feedback control for an electric motor will be designed to permit active damping of these oscillations. The results obtained from simulating the drivelines modeled using Simulation X will be observed for driveline vibrations with respect to the frequency range and also the range in which the jerking frequencies affect the passengers inside the vehicle so as to concentrate on it specifically leading to maximum reduction in jerking of driveline. The models so developed will then subjected to design modifications and investigation in accordance with the control strategies developed and affect of the same will be observed on all the drive train models with level of jerk control achieved. Finally Suggestions will be made on effect of electric motor on hybrid drive train in damping the driveline oscillations, fuel consumption and sportiness of the vehicle also comparing it with the conventional drive train models. Introduction In the age of technology where everyone is concentrating on improving the products by bringing in sophisticated technologies from cars to airplanes, we as human beings neglected the environment factor over the years. 20th century was called an industrial age and much technological advancement have been made in this era which revolutionized the whole world. One of the industries which is closely related to connect our daily life are automobiles. Automobiles have grown rapidly over the years with stiff competition among automotive manufacturers across the world. As the time passed by people become more demanding with their interests widening the automotive market and also the fact that automotive majors started delivering those demands. These technological improvements along with human comfort factors all of us forgot about the effect on environment. The number of vehicles on roads grew exponentially and consumption figures of petrol and diesel across the world increased drastically sending out alarm bells to search for alternate fuel technologies as the conventional petrol diesel were not only running out from their existence but also affecting the environment leading to considerable amount of CO2 emissions and further contributing to global warming. This future problem opened up opportunities for research in alternative fuel technologies leading to the development of Hybrid vehicles, Fuel cell technologies Hydrogen fuelled cars. Few of the alternate fuel vehicles are Toyota Prius hybrid, Honda Civic hybrid, Honda Insight etc which have received good response in the market in terms of performance as well as in reducing CO2 emissions and have successfully proved their presence in the market with their selling volumes and fuel savings. On a smaller level, these developments lead to further research in areas like DC/AC motors, fuel cells, battery pack technology, advanced controller design, power optimization and new concepts which can be used as alternate fuels. Problem Definition Commonly in every engine driven system issue of noise, vibration and harshness (NVH) comes along with it. Automotive manufacturers have always tried to maintain healthy comfort to performance ratio so as to attain maximum customer satisfaction. With respect to comfort of driving, the manufacturers main aims are to provide vibration free driving pleasure as much as possible and the same applied to hybrid electric vehicles. One such area of concern in drive line jerking which affects the overall drivability. Jerking is a kind of driveline oscillations which occurs due to excitation caused by sudden or huge variation in engine torque or driveline load. These excitations cause because of torsional vibration of drive train at high engine torques leading to unwanted longitudinal oscillations of passenger compartment which reduces the riding comfort and drivability. These oscillations have tendency to occur at low engine speeds which are experienced as unpleasant jerking effect by the drive r. Due to the fact diesel engines produce high torque at low engine speeds, makes these engines more prone to this problem. The area of concentration under this case is vibration frequencies ranging between 2- 10 Hz as human body is sensitive towards this frequency range causing unpleasant driving experience. These driveline oscillations majorly occur during tip in and tip out conditions. In conventional diesel engine vehicles methods like active control of fuel injection into engine and passive element such as dual mass flywheel are used to permit feed forward active as well as passive damping of these unpleasant oscillations in idle, tip-in/tip out and coast conditions. To achieve minimal amount of driveline oscillations, vehicle manufacturers have to compromise between comfort and performance of the vehicle. In diesel hybrids, the jerking can be controlled by varying fuel injection and electric motor torque control and also passively by an additional dual mass flywheel (DMF). Aims Objectives The aims and objectives of this project are: To develop a model with three different configurations of powertrain using Simulation X those are: Conventional diesel engine, Conventional diesel engine with DMF and finally hybrid power train with DMF. To study the effects of jerk in each individual power train configuration before developing the control strategy for anti jerk control. To electrify the anti jerk control in hybrid vehicles by using Crankshaft integrated stator/generator to damp the oscillations. To analyze the effect on fuel consumption, comfort and sportiness of the vehicle. To compare the results with conventional fuel control method. Literature Review Hybrid Electric Vehicles Hybrid Electric Vehicle is the one which uses two or more sources of energy to propel the vehicle which consists of an internal combustion engine and electric motor power by batteries. Hybrid vehicles are of various types such as series hybrid, parallel hybrid and combination of series parallel and based on their hybridization factor they are categorized into micro, mild and full hybrids. Figure 1, below shows the typical power split type power train. Generally, hybrid power trains are costly to build due to its complexity but the costs are paid off against the running costs due to improved fuel efficiency. Regenerative braking plays an important role in conserving energy by charging the battery pack. Figure : Showing a Power Split Hybrid Powertrain Types of Hybrid vehicles based on drive train structure Parallel Hybrid In parallel hybrid vehicles, there are two parallel ways for transmitting power to the wheels of the vehicle; those are by engine and by electric drive, as shown in below figure 2. The transmission is coupled with the motor/generator and the engine, allowing either, or both, to power the wheels. Control architecture of parallel hybrid vehicles is more complex compared to a series hybrid due to the requirement of efficient coupling of the motor/generator and engine so as to maintain optimum drivability and performance. Figure : Parallel Hybrid Powertrain Operating modes available in parallel hybrid vehicles are: Engine only traction Electric only traction Hybrid traction Regenerative braking Series Hybrid In series hybrid there is only one way for transmitting power to the wheels of the vehicle, but consists two energy sources. As shown in figure 3, the conventional engine is coupled to a generator for charging the battery pack which provides electrical energy to a motor/generator to power the wheels via transmission. The motor/generator can also be used for recharging the battery during braking and deceleration. Figure : Series Hybrid Power train Operating modes available in series hybrid vehicles are: Electric only traction Electric traction battery charging Battery charging and no traction Regenerative braking Series-Parallel (combined) Hybrid electric vehicles A Series-Parallel (combined) hybrid vehicle has both the aspects Series and Parallel energy transfer paths. As shown in figure 5, a system consisting of motors and/or generators consisting of a gearing or power split device allows the engine to recharge the battery. Changes in this power train configuration can range from simple to very complex type depending on the number of motors /generators and their working terminology. These configurations can be called as Complex hybrids (such as the Toyota Prius and Ford Escape Hybrids), Split-Parallel hybrids, or Power-Split hybrids. Figure : Series-Parallel (Combined) Hybrid Power train Driveline Jerking Driveline jerking also called as driveline oscillations can occur due to many different factors such as load changes, gear shifting and also the condition of the road. In recent times, direct injection diesel engines with extensive refinement of components and significant weight reduction in driveline lead to the problem of driveline jerking. Also with advancement in diesel engine technology over the years, output torque of these diesel engines has risen tremendously for passenger cars effecting the comfort and drivability. The problem with high engine torque is, it causes torsion of driveline due to the gear ratios of the final drive causing the torsion at drive shafts which in turn causes whole power train to oscillate with combined effect of vehicle jerking. Figure 5, shown below show the measurements on a test car caused by tip in behavior in which driver suddenly steps on the throttle combined with high torque gradient and tip out condition, the back out maneuver. Figure : Engine torque and engine speed for tip in and tip out maneuvers. Though the oscillations caused by engine speed are somewhat absorbed by engine mounts but the oscillations due to wheel speed is responsible for horizontal vibrations of the vehicles longitudinal acceleration affecting the performance of the vehicle which is experienced directly by passengers. To restrain these oscillations affecting the comfort and drivabilityfor the passengers, damping of these driveline oscillations is necessary which is referred to as Anti Jerk Control. The oscillations leading to power train jerking in conventional power train can be categorized by the Eigen frequencies of following driveline components: Torsion of shafts causes pitching and jerking due to suspension system, mass of the vehicle and damping. The range of frequency for this cause lies between 2 5 Hz. Also, we know that the natural frequency of the vehicle with respect to pitch motion is lies between 1 2.5 Hz. The frequency of oscillations caused by engine movement and mounts lies in the range of 15 200 Hz. The vibration due to gearbox assembly lies in the frequency range of 50-80 Hz. There are oscillation depending upon the type of engine, no. of cylinders, engine speed and also the combustion process shown in below figure Table : showcasing different engine types and their Eigen frequencies Engine Type Multiples of Eigen Frequency 4-Cylinder ,R4, 4-Stroke 2,4,6,8,10 6-Cylinder,R4, 4-stroke 3,6,9 6-Cylinder,V60,4-Stroke 1,5, 3, 4,5, 6, 7,5, 9 6-Cylinder,V90,4-Stroke 1,5, 3, 4,5, 7,5, 9 12-Cylinder, V60, 4-Stroke 6,12 From the above categorization of the components and their respective Eigen frequencies, the main aim is to narrow down on the components leading to vibrations which are felt by passengers majorly and to minimize the level of vibrations by designing model based predictive control strategy while retaining the performance of the vehicle as much as possible. Hybrid Vehicle Design The power train which has been considered for testing the jerking behavior and the anti jerk control strategy to be designed is shown in the below figure 6. This power train is one of the possible hybrid vehicle architecture consisting of I.C engine, CISG (Crankshaft Integrated Starter/ Generator), Dual Mass Flywheel (DMF), Clutch, Gearbox assembly , High voltage battery pack and power electronics. Figure : Hybrid Vehicle architecture In operation, at lower rpm the vehicle acts as pure electric vehicle powered by the on board battery pack and at higher rpm, both electric drive and I.C engine together produce required power by the vehicle. The percentage of power transmission sharing to propel the vehicle plays an important role in determining fuel efficiency. Design Considerations The components and factors which play important role in hybrid electric vehicle design shown in figure 6 are: Engine design and selection: The I.C engine as in conventional power train plays an important role in hybrid vehicles. Generally, engines designed for hybrid vehicles are smaller in size compared to conventional vehicles. Though the design selection of the engine is completely based on the power requirements of the vehicle. Crankshaft integrated starter/generator (CISG): The starter/generator is device which is controlled electronically. It combines both the functions of a conventional starter and generator into a one single unit. The motive of single CISG unit is replacing the starter as a single entity which is passive in nature; need to replace the old fashioned belt and pulley type connection between the alternator the engine. Also to replace the modern day rotor wound alternators with slip rings and brushes. The integrated starter/generator works as a bi-directional device which converts electrical energy to mechanical work and vice versa. As a electric motor, it assists in starting the I.C engine without any noise and also much quicker than conventional starter. As a generator it produces power required for electrical components of the vehicle and is also used to charge the batteries. Commonly integrated starter/generator is placed between engine and gearbox assembly. The main operating features of ISG are it enables stat/stop, onboard power generation and acts as power assist when required. Figure : Integrated Starter / Generator. Dual Mass Flywheel (DMF): Dual mass flywheel consists of two flywheels connected by long arc travel springs located between I.C engine and clutch or transmission. The first DMF was introduced for the automotive industry in 1985. At that time non lubricated dampers were used consisting of heavy springs which were problematic. Then there was breakthrough in the DMF technology and arc spring type dampers was introduced in 1989 solving almost all the problems which were caused by DMF earlier. Due to the high cost of this product not everyone was interested but was used in large vehicles. Though DMF is a passive driveline element, it has been proven that DMF reduces torsional vibrations to certain extent and plays an important role in anti jerk control of hybrid vehicles also. The operating performance of DMF can be characterized by the spring rate and its damping characteristics. The dual mass flywheel consists of following important characteristics: Primary and secondary inertias. The torsion damper rate. And the damping characteristic. Advantages of using DMF in conventional power train are: Segregation of torsional vibrations: we know that, torsional vibrations are caused by torque fluctuations. A vehicle is a kind of vibrating system with all the components like engine, transmission, drive shafts etc all contributing to the cause. Below figure 8, shows the simple driveline model so as to observe vibration behaviour. In this case engine and transmission are supposed as rotating inertia connected by springs. The spring C2 represents the spring damper characteristics and spring C3 showing the stiffness of the drive train. Figure : Drive train with vibration modes. Figure 9 shown below depicts the fluctuations in vehicle speed and in this case damped resonance occurs at around 1700 rpm. The main aim of DMF is to sideline the vibrations occurring from the engine as far as possible from the rest of the driveline components. Also the figure compares the difference between the extents of vibrations in a conventional drive train compared to one fitted with dual mass flywheel. Dual mass flywheel efficiently reduces the engine vibrations and reduces gear rattle, helps in saving the fuel consumption and also improves driving comfort. Figure : Comparison of vibration damping in a conventional drive train to the one with DMF Transmission assistance: As DMF is said to reduce the engine vibrations, it has positive effect on the transmission system as the stress induced will be significantly less compared to a compared drive line increasing the transmission efficiency and cycle life. Crank shaft assistance: In a conventional power train, we know that flywheel and clutch are connected to engine crankshaft rigidly and due to the inertia of the flywheel high reaction forces are developed on the crankshaft. But in case of DMF, the secondary flywheel can be neglected for bending load case as it connected loosely to the primary flywheel by torsional damper and roller bearings which practically dont allow high transferable reactive forces. The primary flywheel is significantly lighter in weight, more elastic in nature compared to conventional flywheel. Battery pack design and selection: The main criteria in battery design and selection depend upon the capacity, the output characteristics based on type of battery pack to be used, cycle life, cost, scope of reusability and whether recyclable on not. The size and weight of the battery pack depends on the capacity requirement. If capacity is high, more will be size and weight of the battery pack. In fact, battery pack design plays a very important role as the performance of the vehicle is dependent on the overall weight of the vehicle. In case battery pack is heavier, this would have direct impact on the power consumed to propel the vehicle which is set to rise with increase in battery weight and will also reduce the operating range of the vehicle. Figure : Typical Battery pack arrangement Electric Motor: Generally AC, DC and PMDC electric motors are used in hybrid vehicle depending upon the requirement and usage. In automotive industry, certain motor specifications are not acceptable due to their inability to meet the specific requirements such as power rating at peak load conditions, continuous power supply, volumetric power density, cost, efficiency, weight, lifetime, level of protection against water and dust. Gear box assembly: In hybrid vehicles, mostly a power splitter device is used which is consists of planetary gear set allowing power flow from two power generating sources to propel the vehicle. The I.C engine is generally connected to Sun gear while electric motor is connected to the planet gear. Clutch: It is found in every vehicle with manual gearbox. Though the use of clutch varies from one hybrid drive train to another depending the gearbox being used as most of the hybrid power trains use automatic transmission which dont require clutch. The main purpose of clutch is to assist the vehicle starting off from stand still position as it compensates for the speed difference between engine and the driveline and slips on to synchronize both. Clutch also used to engage and disengages engine from the transmission while gear shifting takes place. Modelling Approach Procedure of work Power train jerking in hybrid vehicles is majorly due to engine electric motor torque changes during tip in and tips out operations. For investigating the problem of jerking for a hybrid vehicle, certain steps have been laid out for modeling the power train in five different steps which are in below figure 9 to observe and analyze each case individually with root cause: Figure : Modelling Procedure Basic Driveline Equations Engine: The engine output torque is expressed by the driving torque (Te) generated from combustion , friction torque (Tfric,e) and the external load from clutch (Tc) .By Newtons second law of motion, we can achieve the following model: Where Je is the mass of inertia of the engine, is the crank angular acceleration. Clutch: Generally a friction type clutch is installed in vehicles with manual transmission connecting to the engine flywheel and input shaft of the transmission. During clutch engagement if we assume no internal friction, Tc = Tt can be obtained. Then the torque transmitted is function of angular difference (ÃŽÂ ±cs ÃŽÂ ±c) and angular velocity difference ( ) resulting in: Figure : vehicle driveline with corresponding angle and torque labels. Transmission: A transmission consists of a gear set each with a different operating ratio it leading to relation between input and output torque Where Tp is the transmission output and Tfric is the internal friction torque of the transmission. Propeller shaft: The shaft which connects the transmissions output to the final drive unit in which no friction is assumed which gives us Tp = Tf , resulting in model for torque input to final drive Final Drive: final drive can be considered as a final ratio if as for the transmission leading to input and output torque relation Drive Shafts: The shafts which connect wheels to the final drive are called drive shafts. It can be assumed that both the wheels are rotating at same speed ( ). Ignoring the vehicle dynamics, the wheel speed shall be equal to speed of vehicle bodys centre of gravity. Therefore, drive shafts can be modelled as one shaft. Wheels: The forces acting on a vehicle with mass (m) and velocity (v) the longitudinal forces (FL)acting on the vehicle gives Rolling resistance (Rr) = f*m*g and Aerodynamic drag (Ra) =1/2*Af*Cd*à Ã‚ *V2. Where, m=mass of the vehicle, g=gravity constant, f=0.015(co-efficient of rolling resistance), Rr=rolling resistance, Ra=aerodynamic drag, Af=cross sectional area, Cd=coefficient of drag, density (à Ã‚ ), V=velocity. The drive line model can be expressed as a system consisting of rotating lumped inertias, compliances, damping losses, input torque and loads acting due to environmental resistive forces. A simple 2 degree of freedom model (fig 10) is sufficient to show the first torsional mode of vibrations which lead to jerking of vehicle. Figure : Free body diagram of a conventional driveline Where, Teng = engine torque, road load = Tload , e = engine speed, v = vehicle speed, Je = mass moment of inertia, be = viscous friction, r = final drive ratio, Ks CS = drive shafts flexibility, Cw = damper, vehicle inertia = Jv. Hybrid Power train Model As discussed earlier in report, the hybrid power train consists of additional components compared to conventional type which include electric motor, batteries, power electronics which form together the electric drive unit of the vehicle. Engine: Engine in hybrid power train plays a very important role in terms of fuel savings and vehicle assist. An engine model to be used for hybrid power train must be considered for following issues: The engine model must produce desired torque output irrespective of operating conditions. The engines dynamic behaviour leading to torque fluctuations generates drive line vibrations which in turn affects the driver comfort. As engine is not quick enough to respond to control actions implemented externally, the response delay can have significant affect on the vehicles performance. Engine can be modeled in many different ways depending upon the level of complexity required and the availability of parameters which can later be used for validating the inputs. The basic equation of engine model has been already discussed earlier which can be applied for the hybrid power train model also. Electric Motor/ Controller: The electric traction motor and controller consume the power from the onboard energy storage device like battery to provide the power source so as to generate the required torque for vehicle propulsion. The electric motor can also be used as starter/alternator or as a generator to recover energy during braking which can be used to charge batteries. The traction motor model can be described by following equations: Where idr , iqr are d,q axis rotor current respectively; ids ,iqs are d, q axis primary current respectively; Lm, is mutual inductance; Lr , LJ are resolved rotor, stator inductance respectively; P are poles; Rr, Rs are resolved rotor, stator resistance respectively, ohms; Vds Vqs are d, q axis primary voltage respectively, V; ÃŽÂ »dr and ÃŽÂ »qr are d, q axis rotor equivalent flux respectively, V-sec; ÃŽÂ »ds and ÃŽÂ »qs are d,q axis stator equivalent flux respectively, V-sec; à Ã¢â‚¬ °e is synchronous frequency, rps ; à Ã¢â‚¬ °r is rotor frequency, rps; , is rotor acceleration, rps2; Ts is electric motor torque, Nm. The limiting torque of the motor can be expressed by: Where à Ã¢â‚¬ °b, is motor base speed, rpm; à Ã¢â‚¬ °m is mechanical motor speed, rpm; Prated is the rater motor power, hp; Trated is the rated motor torque, Nm; Tm is mechanical motor torque, Nm. In addition to this, equations of motion for DC electric machine are: Where is the torque output of the machine proportional to the armature current, e is the back emf of the machine is proportional to the velocity of the rotor Drive Shaft: The drive shaft plays very important role in the drive train for transmitting the torque and rotation. They are subjected high torsion and shear stresses and therefore must have must have high stiffness. Below shown in the drive modelled using lumped inertias and their corresponding basic equations TDS =KDS (ÃŽÂ ¸T ÃŽÂ ¸W) + CDS (T W) Wheels: The forces acting on a vehicle with mass (m) and velocity (v) the longitudinal forces (Fe)acting on the vehicle gives Stationary model of the vehicle assuming all forces act through the centre of gravity and only in longitudinal direction. Gears: Assuming no losses in transmission the basic equation for gearing is But in reality there are viscous losses, sealing bearings drag contact friction. Losses vary with gear change but can be modelled as a loss torque tl acting on the transmission input shaft there can be shown as: Capacitor: It is device which stores energy an can be modelled by current equation Battery: Batteries are characterized by energy density, C-rating, cycle life, thermal run away and variations in temperature.

Creating simulation models for hybrid power train requires various components of power train such as mechanics, hydraulics, electronics and pneumatics including the control aspects involved.

Can the nation-state and culture combine forces to reduce interpersonal violence in the West?   Ã‚  Ã‚  Ã‚  Ã‚  Violence is a difficult term to define, but for the purposes of this assignment violence can be defined as a crime or the threat to commit a crime by one person upon another person, and that usually that has negative physical or emotional effects upon the victim. Violence in Western society has been increasing steadily and has become a major concern for many nations. Increasingly, much of the violence is committed by male children and teenagers. Crimes by young people are no longer just misdemeanors, but they now include the major felonies of rape, robbery and homicide. The rise in violent crime in the last few decades has been accompanied by a rise in violence in the media, especially television, movies and music. To protect society, the US government must impose regulations on these media outlets so that audiences are not subjected to too much gratuitous violence that may influence them to commit such acts of violence.   Ã‚  Ã‚  Ã‚  Ã‚  Much of Western society’s contemporary behavior is influenced by popular culture, usually by such media outlets as television, movies and music. Arguments exist today concerning the amount of responsibility that the media has to portray such violent crimes as unacceptable. The most popular of such beliefs is one that argues that the media is currently romanticizing the use of violence to gain an audience. Proponents of such an argument claim that if the media displays violence in a less glamorous way, interpersonal violence can be reduced. For this to happen, the nation-state must play the important role of regulating how much and what types of violence media sources can show, and to which audiences.   Ã‚  Ã‚  Ã‚  Ã‚  Some people, mostly men, enjoy viewing or hearing about acts of violence. Some even find it exciting to participate, on one level or another, in violent acts. Television programs, movies and music capitalize on this fact by showing or describing gratuitous acts of violence. Even news programs see the importance in covering violent interpersonal crimes in their broadcasts to gain high ratings. Western society is interested in conflict, and enjoys being a third party audience to such violence. The problem with this is that by consuming too much violence through th... ...duce more violent behavior from their audiences. The governments of the Western world cannot altogether prohibit the media from showing violence to their citizens, but they can impose more strict limitations on the amount of violence shown and to which audiences. More mature audiences can handle violent content better than younger, more impressionable audiences.

To protect society, the US government must impose regulations on these media outlets so that audiences are not subjected to too much gratuitous violence that may influence them to commit such acts of violence.   Ã‚  Ã‚  Ã‚  Ã‚  Much of Western society’s contemporary behavior is influenced by popular culture, usually by such media outlets as television, movies and music. Arguments exist today concerning the amount of responsibility that the media has to portray such violent crimes as unacceptable. The most popular of such beliefs is one that argues that the media is currently romanticizing the use of violence to gain an audience. Proponents of such an argument claim that if the media displays violence in a less glamorous way, interpersonal violence can be reduced. For this to happen, the nation-state must play the important role of regulating how much and what types of violence media sources can show, and to which audiences.   Ã‚  Ã‚  Ã‚  Ã‚  Some people, mostly men, enjoy viewing or hearing about acts of violence. Some even find it exciting to participate, on one level or another, in violent acts. Television programs, movies and music capitalize on this fact by showing or describing gratuitous acts of violence. Even news programs see the importance in covering violent interpersonal crimes in their broadcasts to gain high ratings. Western society is interested in conflict, and enjoys being a third party audience to such violence. The problem with this is that by consuming too much violence through th... ...duce more violent behavior from their audiences. The governments of the Western world cannot altogether prohibit the media from showing violence to their citizens, but they can impose more strict limitations on the amount of violence shown and to which audiences. More mature audiences can handle violent content better than younger, more impressionable audiences.

Historical Foundations in the Field of Psychology Essay

Abstract This final assignment is a reflective paper in which the historical, philosophical, and empirical foundations of the field of learning in psychology and its applications will be discussed. Additionally, there will be a discussion of the ways that history has helped to shape important contemporary learning theories and issues. Lastly, the paper will provide an explanation of how specific topics and information such as instrumental conditioning techniques and the usefulness of different learning styles may impact my personal and professional life and how the different aspects of the ield of learning have added value to my body of knowledge as a student and future professional in the field of psychology. Historical Foundations Of the Field of Learning & Shaping Important Contemporary Issues It is a natural course of action for the field of learning to fall under the umbrella of the field of psychology. A branch of philosophy and science, the field of learning, Just as the field of psychology, was created through the movements of empiricism and rationalism, along with the development of evolution theory (Terry, 2009). These movements fostered interest in scientific investigation thus giving way to pistemology, which means, theory of knowledge. Questions concerning nature and nurture sparked interest in how we came to have knowledge, which is the main tenet of the field of learning (Terry, 2009). In the field of psychology, the learning theories provide a way to explain how we learn and attain knowledge; how we think. While philosophers agreed with the basic definition of knowledge and learning, which is defined as the acquisition of knowledge, their opinions varied in how acquisition occurs (Terry, 2009). Descartes suggested that although we learn, other sources of knowledge exist. He introduced the ideas of nativism and rationalism. He proposed that we have innate knowledge of our ideas of God, infinity, and perfecton (Terry, 2009). Also, that other knowledge is derived by a reasoning, logical, and intuiting mind (Terry, 2009). Additioally, this knowledge is present and independent of particular experiences with the world (Terry, 2009). Therefore, he believed in the process of learning, but he didn’t believe that all knowledge had to be learned. However, John Locke introduced the idea that knowledge is actually learned through our experiences, and through use of our senses, which is the idea of empiricism (Terry, 2009). This phenomenon is later known as cause and effect. The ideas of Descartes and Locke influenced researchers toward an empirical view of learning through seeking out how knowledge is acquired through what is experienced in the environment. This gave way to the scientific methods of association learning, conditioning, and verbal learning (Terry, 2009). Each of the historical thoughts on learning is continuous and useful in some way today. There are modern theories that have built upon the ideas of conditioning and behavior modifications, etc. One (2006), provide a modern approach to treating phobias, as well as other anxiety isorders. Their research starts with the traditional premise that what can be learned can be unlearned, and possibly prevented (Mineka ; Zinbarg, 2006). However, they support modern criticism that traditional learning approaches do not adequately account for the diverse factors involved in the origins of people’s anxieties. To support this claim they provide an example of two clients with phobias of dogs. The phobias were developed due to experiencing attacks by dogs. The first client actually was out walking her pet dog when she was attacked and later developed an infection due to the bite. However, the second client only experienced her clothes being torn before the owner was able to grab the dog before any serious injury occurred, although both clients developed phobias (Mineka & Zinbarg). They argue that traditional learning approaches do not adeqatly explain why the client that was not bitten developed the phobia as well. Additionally, they provide another concern that traditional views do not explain why many individuals that have had traumatic experiences do not develop phobias. Furthermore, they go on to say that contemporary learning approaches are better grounded in the theories and ethods of experimental psychology, and they provide more comprehensive formulations of the etiology of anxiety disorders. Also, that they provide a more explicit analysis of factors promoting or inhibiting the deeopment of different anziety disorders (Mineka & Zinbarg). With that being said, there have indeed been great advancements in the field of learning and psychology, along with growing technological advances. Learning involves observable changes in behavior; objective evidence, and traditional researchers such as Pavlov, Watson and Skinner have paved the way for providing a scientific foundation for psychology and learning. Psychology is a science because it is objective and quantifiable. Learning and memory themselves are not observed directly; they are processes that occur in the nervous system (Terry, pg. 5, 2009). Therefore, contemporary research has taken advantage of the use of PET scans and magnetic resonance imaging (MRI) to look at brain functions to explain behaviors ( Raichle, 1994). These modern avenues of research have allowed researchers to become a step closer to relating psychological theory to brain functions and research. For example, todays research may include brain scans and case studies of brain damaged soldiers. Even mor e so, recent research on post traumatic stress disorder examines the use of exposure therapy on preventing the reoccurenc of PTSD (Massad et. l, 2006). This research is most interesting because the researchers examine the understanding of reducing fear responses because associations with the stimuli are not unlearned. Their research concludes that unless exposure treatment regimens are maximized the risk of renewal of PTSD is high (Massad et. al, 2006). Such advances are very important to the quality of life that our existence depends upon. Knowledge is necessary for our daily lives even more so now than ever. This very research can be instrumental in a military soldiers life as we are currently in war time. The topics in the field of learning that have had the most impact on me personally include learned taste aversions and the development of specific phobias For probably will not cause the child to cry. However, through the pairing of the needle with the unpleasant sensation of having a vaccination the sight of the nurser may come to elicit symptoms of fear and anxiety, even if the child is not receiving a vaccination. I personally found this interesting Just because I am a mom and it is interesting to use such information while rearing children. The second type of learning that I found interesting in the behaviorist tradition is instrumental or operant, conditioning. This type of learning requires that an organism operate on the environment to achieve a goal (Terry, 2009). So then, behaviors are learned as a function of the consequences of those behaviors. Of course, this type of reinforcement is useful in the classroom as well as rearing children. Additionally, social learning theory focuses on observational learning, and modeling. Social learning researchers are concerned with how expectations, memory, and awareness influence the learning process (Berk, 2008).

Innovation Strategy at Microsoft Essay

Microsoft Corporation is an American multinational software corporation that develops, manufacturers, licenses and supports a wide range of products and services related to computing. Microsoft is the world’s largest software maker and affects millions of users worldwide every day. The company recorded all-time high revenue bringing in $73.7 billion for fiscal year 2012. After analyzing this case, I have concluded that the main problem for Microsoft is that their deep silos are inevitably hindering its ability to produce products and/or services to compete with current computing trends in the industry. While Microsoft continues to dominate the computing world, it cannot be attributed to their innovation strategy. To address these problems I suggest that Microsoft alter their environment to better simulate innovation. Microsoft should create an environmental culture in which employees are encouraged to venture outside their tasks, minimal time pressure, and high job security give positive feedback for initiatives taken. These recommendations are based on specific concepts from the book. Current environment inside Microsoft does not currently provide positive feedback. Their current environments sets commitments for each division and employees are faced with performance evaluations. When employees failed to meet designated commitments, employees were penalized. Additionally, employees are penalized for taking on activities unrelated to their commitments. First in chapter 6 we saw that in an industry where growth is slowing and competition becomes stronger, an organization’s success requires innovation. This is why it is recommended that Microsoft focus on simulating innovation. We saw that innovators derive from individual developers and thereby can be considered the true source of innovative products. While an organization system model and creative individuals are key stakeholders in the business, it is not enough to drive innovation. Per chapter 6, there are several effective ways to simulate innovation- of which are the recommendations suggested above. Innovation Strategy at Microsoft: Clouds on the Horizon ACC – Applied Carbon Corporation (large environmental technology conglomerate) EBC (Executive Briefing Center) Innovation team- Gates was engaged with the engineer and the algorithm, he talked about how the algorithm that could increase the speed of the search This suggestion by Gates reduced time used on massive server banks Later he proposed an innovation to monetization model that would save corps millions of energy time. Innovation at Microsoft: Top-Down or Bottom-Up? Innovation drivers: Product groups, Microsoft Research labs, Innovation teams generating grassroots innovation Innovation at Microsoft really was a â€Å"one-man show†, vision and drive of a senior leader, i.e. Gates, then would work its way down Gates would send out memos calling for dramatic change in products, services and technologies Microsoft offered Extensions on existing products & services – result of product groups New products & services accounted for 1/3 Microsoft Rev Grassroot Innovation Grassroot innovation- attempt to tap into diverse ideas of Microsoft employees & turn into profitable new businesses Participated in ThinkWeek, Quest, IdeAgency & Innovation Outreach Program ThinkWeek- technical papers submitted once a year directly to Gates who reviews them for a week & makes comments Quest- Similar to ThinkWeek but involved Microsoft’s most senior & accomplished technical minds Thinkweek & Quest tapped into minds of senior technical staff- ignored other employees IdeAgency- to full realize potential in grassroots innovation by all Microsoft employees Executive sponsor (most likely product group leader) identified a prb that needed a solution & all employees through an IdeaExchange tool would submit solutions Learning by doing- needed more adjustments- submitting ideas wasn’t enough. Therefore top ideas of IdeAgency were selected (ie. 300 first session), form groups, were given a budget & resources to develop a prototype within 8 weeks. ThinkWeek, Quest, IdeAgency- all internal request for info, IOP implemented to include public Chief innovation officers from 10 Microsoft largest accounts for two-day innovation brainstorming conference- asked to look 5 years ahead (LT ignore ST) Steep believed this would drive innovation b/c had two critical flows of information done in product groups & Microsoft research labs 1. Top-down guidance 2. Bottom-up expertise The Information Technology Industry: Clouds on the Horizon Grassroots innovation initiatives response to increased competition from all sides (apple, amazon, google, linux and others) Microsoft generated most rev from consumer & enterprise licenses for software products ’08 operating income $22.5B on rev of $60. 4B (15% growth rate) New technologies threaten importance of Windows operating system as a universal platform, undermining traditional licensing model used by Microsoft for so long Microsoft business model relied heavily on product groups within divisions while each group tailored its software development process to its core technology & market Product groups worked closely with Sales, Marketing & Service division to deliver on customer needs Again, licensing model has been successful for Microsoft but many business analysts that shrink-wrapped software method of generating revenue will be obsolete and lose to cloud computing items 2000 Apple launched MobileMe Yahoo implemented online advertising business model Amazon online service & transaction business model Google online info search leader Grassroots Innovation under Microscope Product groups focus on ST & Research labs on LT So many processes running concurrently with lots of capital tied into them – is Microsoft delivering on its process? The ThinkWeek & Quest relied heavily no Gates- so what if he departed? IdeAgency great on paper- while delivered many successes, few drawbacks- immense time required to facilitate Too many hurdles trying to make fruitful collaborations in resistant environment Too much effort to get anything going across the product groups Many employees refused to work on projects beyond their defined objectives and commitments out of fear of receiving poor evaluations Organization Structure & Design Three divisions: Platform Products & Services, Microsoft Business & Entertainment & Devices Deep silos that barely communicated or collaborated Three business divisions, seven business groups & 27 product groups were told to focus on its own individual profit/loss. Business groups didn’t have time or incentive to participate in collaborations away from their own group Culture & Beliefs Developer-centric company b/c most employees possessed extraordinary amount of tech expertise- every employee (even senior mgmt.) had small office with a closed-door policy to concentrate better Culture a result of Gates behavior and mgmt. system driven by 3 core beliefs- 1) individual excellence (believed they had brightest employees in the world) 2) competitive behavior 3) accepted to never accept 2nd best (Go Big or Go Home) These believes lead to extreme intra- and interfirm competition intensity Competition amongst each other for positions Personal meeting with Gates & his lieutenants in which major employees are dissected & reviewed (can make or break your career at Microsoft) Culture & Beliefs Individual & group incentives were primarily influenced by â€Å"commitments† tied to each employees output- detailed objectives stated in form of a contract between employee & supervisor. At beginning of year commitments set in stone & couldn’t be changed.

Free Essays on Designing and Managing a Sales Force

Summary: 5 pages. 4 sources. MLA format. This paper discusses how businesses should design a sales force and how managers can effectively manage that sales force. Designing and Managing a Sales Force Introduction U.S. businesses spend over $140 billion annually on personal selling (Anderson, 1995 and Dalrymple, 1994). This is more than they spend on any other promotional method. Furthermore, over 11 million Americans are employed in sales and related occupations (Anderson, 1995 and Dalrymple, 1994). Sales forces are found throughout the business environment from the insurance industry to college recruiting and just about everything in between. According to author Philip Kotler, sales personnel serve as the company’s personal link to its customers (p. 620). Kotler asserts that â€Å"the sales representative is the company to many of its customers† since it is the salesperson who delivers information to the customer (p. 620). Therefore, a company must carefully consider how to design and manage its sales force in order to be successful in the marketplace. This paper discusses how businesses should design a sales force and how managers can effectively manage that sales force. Designing a Sales force When designing a sales force, a company must thoroughly deliberate several issues in order to establish an efficient sales system. These issues are: the development of sales force objectives, strategy, structure, and compensation of the sales force (Kotler, p. 620). Sales force objectives are the specific goals that companies expect their sales representatives to achieve (Kotler, p. 620). A typical example of how companies delineate an objective is the establishment of sales quotas for their sales representatives. Sales quotas inform a salesperson of exactly what their objective should be for a given period of time. Additionally, besides quotas, there are other ways of delineating sales objectives.

Case Study of Ms Foley-Free-Samples for Students-

This assignment is about a patient named Ms. Martha Foley, a 35 year old lady who is suffering from acute pulmonary oedema and was admitted in the hospital prior to 5 days because of post multi-trauma caused by a car accident. She is also suffering from multiple fractures in both legs and smoke inhalation as being trapped in car for 15 minutes. This paper has been divided into two parts. Part 1 contains the description of Ms. Foley and her history along with the treatment in the hospital and the analysis of the Observation Chart and Fluid Balance Chart. It also contains a brief description of acute pulmonary oedema, its pathophysiology and the implications of nursing assessment of this situation. Part 2 contains the inter-professional model of care required for Ms Foley while in hospital. Ms. Foley is a full time worker at a supermarket and is a victim of domestic violence from her former partner. She had a good relationship and support from her friends and co-workers. The day of the accident she and her friend Ms. Annie Jones were travelling in the same car. Ms. Jones was also admitted in the same hospital. Ms. Foley was a smoker of 10 cigarettes per day and also intake drugs such as methamphetamines IV and cocaine. But don’t drink alcohol and is a vegetarian. She had suffered from left sided heart failure in the past and is treated by cardiomyopathy. Fluid balance chart describes that Ms. Foley is given compound Sodium acetate was given intravenously from 01:00 am to 08:00 am at 200mls per hour and only 100mls is drained out through urine. It has been shown in appendix 1. Observation chart describes about the general physical conditions of Ms. Foley during the time of her admission in the hospital. The following things were measured: Acute pulmonary oedema is a type of disease in which the alveoli gets filled up with fluid and the person is unable to breathe. As the fluid gets accumulated creates misbalance in exchange of gases and leads to dyspnoea and hypoxia. Acute pulmonary oedema (APO) is caused by two main mechanisms. The first mechanism is elevations in pulmonary pressures due to severe increase in intra-cardiac pressure of chambers and second is severe lung injury causing increase in pulmonary vascular permeability (Liesching et al. 2014). Pulmonary oedema caused due to lung injury is termed as acute respiratory distress syndrome (ARDS) while pulmonary oedema which is due to acute elevations in pulmonary micro vascular pressures is termed acute cardiogenic pulmonary oedema (Lavin et al. 2015). The pathophysiology of these two types of oedema is almost different due to which their treatments are also different. This document relates specifically to acute cardiogenic pulmonary oedema (Zeiss 2016). Acute cardiogenic pulmonary oedema is caused by an intense ischemic occasion bringing about cardiovascular brokenness. Intense diastolic disappointment may likewise be caused from hypertension and atherosclerosis. Less generally the intense sight might be optional to other essential occasions, for example, intense valvular issue or arrhythmia (Elias et al. 2015). The acute cardiac dysfunction that happens from a background marked by myocardial ischemia brings about expanded cardiovascular end diastolic weights which thus result in hoisted pneumonic micro vascular weights and the improvement of intense cardiogenic aspiratory oedema (Vlaar and Juffermans 2013). There is a decrease in cardiovascular yield with ensuing solid enactment of the thoughtful sensory system and the renin-angiotensin framework. This outcomes in lifted blood weights and expanded delayed consequences on the heart starting a gooey cycle of expanded myocardial oxygen request and further lessening in cardiovascular yield (Luks et al. 2014). In the problems of heart failure there are homeostatic systems that prompt liquid maintenance and pneumonic blockage. In APO there might be starting of liquid fill up, however the essential pathophysiology won't be reliant on the benchmark liquid status. It is significant that s number of these patients is hemoconcentrated on introduction because of the gathering of up to 2 litres of liquid in their lungs (Spoletini et al. 2015). They may then show up hemodiluted 24 hours after the fact when they are in the recuperation stage. As it were they give off an impression of being enduring a more prominent plasma volume as of now, which is suggestive that the issue is not fundamentally a liquid over-burden issue. By and large of APO the issue is less liquid abundance; rather it is an instance of liquid in the wrong "compartment", (intra-alveolar, as opposed to intra-vascular) (Duffy et al. 2015). The nursing care plan depends upon the appearance of the patient’s respiratory status. To perform the assessment of nursing care for acute pulmonary oedema the nurse must observe the individual’s responses (Akoumianaki et al. 2014). The following are the therapeutic nursing interventions for  acute pulmonary oedema: The initial management of patients with cardiogenic pulmonary edema (CPE) should address the ABCs of resuscitation, that is, airway, breathing, and circulation. Oxygen should be administered to all patients to keep oxygen saturation at greater than 90%. Any associated arrhythmia or MI should be treated appropriately (Lumb 2016). Methods of oxygen delivery incorporate the utilization of a face covering, non-intrusive pressure support ventilation (which incorporates bi-level positive aviation route weight [BiPAP] and consistent positive airway pressure [CPAP]), and intubation and mechanical ventilation (Stocker et al. 2014). The method that will be utilized relies upon the proximity of hypoxemia and acidosis and on the patient's level of cognizance. For instance, intubation and mechanical ventilation may end up noticeably important in instances of tireless hypoxemia, acidosis, or changed mental status. The utilization of non-intrusive weight bolster ventilation in acidotic patients with serious intense cardiogenic aspiratory oedema does not give off an impression of being related with unfavourable results (early mortality and intubation rates) in these patients (Adam, Osborne and Welch 2017). Initial dose: Frusamide is given intravenously and the dosage is 20-40 mg (slowly for 1 to 2 minutes) or may increase the dosage by 20 mg later by 2 hours after the previous dose until the desired diuretic effect has been obtained. Use: Treatment of oedema associated with congestive heart failure, cirrhosis of the liver, and renal disease, including the nephrotic syndrome, especially when an agent with greater diuretic potential is desired (Soni et al. 2017). Initial dose: 20 to 80 mg orally once; may repeat with the same dose or increase by 20 or 40 mg no sooner than 6 to 8 hours after the previous dose until the desired diuretic effect has been obtained. Maintenance dose: Administer the dose that provided the desired diuretic effect once or twice a day. Maximum dose: 600 mg/day in patients with clinically severe oedematous states. -Oedema may be most efficiently and safely mobilized by giving this drug on 2 to 4 consecutive days each week. -When doses greater than 80 mg/day are given for prolonged periods of time, careful clinical observation and laboratory monitoring are particularly advisable. Use: Treatment of oedema associated with congestive heart failure, cirrhosis of the liver and renal disease, including the nephrotic syndrome, especially when an agent with greater diuretic potential is desired. The Inter-Professional Model of Patient Care (IPMPC ©) was introduced in 2006 when inter-professional collaboration started as a priority of policy agenda in Canada. This model causes the experts to enhance better care the patients and their families which likewise can manage the extra issues of human medicinal services. The models speak to a pedantic program, a group based affair and a between proficient recreation encounter. The instructional program stresses between proficient group building abilities, information of callings, tolerant focused care, benefit taking in, the effect of culture on medicinal services conveyance and a between proficient clinical segment (Maggiore et al. 2014). Nurses were ready for Ms Foley to attend her while she was lying flat on her bed, trying to sit up, and gasping for air. She is worried, stating she is ‘scared’, and that she has a weird feeling that she can only describe as ‘a sense of impending doom’. Vital signs taken and are the following: Pulse 120bpm and regular, BP 100/50, RR 34, SaO2 92% on RA. Her lips have started to turn blue and the nail beds on her fingers are cyanotic. She remains dyspnoeic and desperate for air. She is coughing. The integral part of inter-professional care of nursing is quality improvement. ACHS is a handbook which gives information of management of risks and improvement of quality to assist organisations and to manage the risks at the organisational levels and to ensure that quality of care and services are integrated (Powell et al. 2016). PE teams have found their place in health care. Teams do not replace the physician-patient relationship, but rather enhance it—creating a more comprehensive, efficient, and tailored health care experience (Short et al. 2014). The care convention was created by the IP group amid a CPE workshop and encouraged group gatherings. It was utilized as the guide by medical caretakers or doctors associates who gave mind at the visits. Components of the IP mind convention included visual signs, for example, publications on the exam room dividers that represent the body frameworks affected by diabetes, and an envelope with data, worksheets and apparatuses created by the IP group on parts of connecting with relatives for help, eating regimen, exercise and medical administration. Thus through the above discussion it can be concluded that Ms. Martha Foley had an accident and detected by acute pulmonary oedema which is a type of disease in which the lungs is filled up with fluid. At first in this task there had been included clinical assessment tools; pathophysiology and its applications; nursing care plan; nursing interventions; pharmacological uses of frusamide; inter-professional model of care, its risk management and its implications Adam, S., Osborne, S. and Welch, J. eds., 2017.

International Marketing Plan Of An Australian Brand Case Study

International Marketing Plan Of An Australian Brand - Case Study Example Penfolds Grange is basically a red wine that is manufactured totally in Australia and has been a leading brand in the Australian as well as the international market since its inception in 1951, ever since then it has won over 50 gold medals in vintage wine competitions and has been a major influence in the international arena as well. It is made from 2 kinds of grapes: the Shiraz and the cabernet sauvignon, the Shiraz being the major component where as the cabernet sauvignon is only used in small portions.Product Description: Penfolds is one of the major labels in the Australian wine industry and is a major exporter to a multitude of companies in the world; it has been one of the best red wine brands ever since its inception in 1951 and has been a major award winner in its category. The relative advantage of this brand is that it is made from an unusual blend of grapes that are specially grown at the company’s vineyards and hence is a unique red wine and has been able to set s tandards of its own. Since Penfolds is a major brand, it is exported to various countries in the world, the country that has been chosen for the purpose of this paper is the United Kingdom which is a major wine consumer nation and wine is a commodity which can be categorized as a house hold item which is consumed on a regular basis. Since wine is consumed on a nation wide basis, penfolds would be tried by consumers more often than not and hence it is very compatible with the tastes of the people in the country.on the country. There would not be any major limitations to the product because it is a widely acceptable product in the target market but the only issue that the product will have to over come is that there would be competition and it should implement strategies so that it is able to over come this major obstacle. There are no limitations as such to the product because it comes in various shapes and sizes and hence it can very easily be picked off the shelf by people with var ious purchasing power. Environmental Scan: The general dynamics of the country at hand have to be studied in order to truly understand the country and also to devise a plan to cater to the market. The essentials that need to be studied while scanning the environment are the family structure, education within the country, social organizations, religion, the diet and in this case it is extremely important to know the climatic conditions and it is extremely important that days of festivity have been pin pointed because these are the days when people would be more inclined to consume red wine and it is extremely important that once these days have been identified they are utilized to the maximum. The literacy rate in the United Kingdom is 99% and that is basically due to a public sector educational system which disseminates free education to all and this has been one of the plus points of the British economy for a very long time now, the ability of the consumers to think rationally will definitely influence th e decision to choose Penfolds because customers can then be made to think rationally by effective advertising. Diet and nutrition in the UK is of the optimum level and malnutrition or what so ever of that had

International perspectives in organisation Literature review

International perspectives in organisation - Literature review Example According to Javidan et al. (2006), global leadership is one of the critical factors in the management of large multinational corporations. In their paper titled â€Å"In the eye of the beholder† the researchers particularly use the research findings from the Global Leadership and Organizational Behavior Effectiveness (GLOBE) program as a basis for conceptualizing the global leadership differences. Generally, Javidan et al. (2006) effectively presents the cultural profiles of four countries namely France, Egypt, Brazil and China as a case study to highlight the potential cultural implications of a hypothetical American executive working in the business environments in these countries. Javidan et al. (2006) particularly suggests that cross cultural leadership should represent an open mind and understand overly the cultures of different countries. Mangers should be critical and analyze empirically the cultures of their countries’ to the cultures of the people in the countries of their business operations. Managing and leading in different counties: The corporate management should be considerate on the types of marketing activities across the different countries of their operations. Both the dominant and metropolitan countries managerial schemes should be in an equilibrium and modal way of management. Regional clustering of globe nations: The business corporate world is prone to completion. Through these competitions, a global cultural clustering is therefore eminent with about 62-case studied culture clustering from America continent through to African continent to Asia and Europe (Jovidan et al, 2009 p.122). The study concludes by highlighting practices such as the ability of the individual global managers to share information about their culture alongside the culture of the host country, contemplate bridging the gap between two diversified cultures, to exhibit a high level of ambiguity tolerance and to remain

Analytic review - Essay Example Both Thesydides and Aristophanes treat Cleon with clear despise. At the same time, their texts offer sufficient evidence that the political relationship between the Athenian political leaders and the demos was erotically colored. It is eroticism that serves the background of both Pericles and Cleon’s political activity as opposites. In this case, Cleon has been historically perceived as a mere parody of Pericles. He seems to have embodied all features that are not characteristic of Pericles as depicted by Aristophanes. At the same time, this vision helps to reveal much about Pericles. Dr Wohl relies on reading their politics not just through the specific features exhibited by Cleon and Pericles, but through understanding the essence of the eroticism inherent in political visions of the demos and its leaders. This leads to emergence of an elaborate political erotica. Within the limited societal model represented by Athens, the politician and the orator at once gets the support of the demos through violent eros. His open mouth epitomizes his desire to make his listeners open their orifices, too. So they gape at him. Erotically, this pederastic relationship puts the orator in a position of eromenos. This is how Cleon is viewed by Thusydides. Pericles, on his part, is believed not to descend to using the violent eros with fellatio and other sexual practices due to his authority. He sublimates the sexual desire into his authority. Yet, the demos retains his sexual desire which is repressed. The difference is Cleon acknowledges the desire and builds his erotic relationship with the demos on this, while Pericles does not, although he also acts in the same paradigm. In the last section of the chapter, Cleon’s political style is analyzed in terms of his rhetorical eros and then compared with that of Plutarch’s Pericles. For Cleon, this rhetorical eros is the essence of democracy, when the orator pleases the demos by the effeminizing

Gender, Culture, and Globalization Essay Example for Free

Gender, Culture, and Globalization Essay In the Western world, the cause of feminism enabled women to obtain higher education and participate in the economic sector as the equals of men. However, one question that continues to be of interest to modern scholars is: how far have women truly come globally? Not only in Western democracies, but in developing nations located in the Middle East, Southeast Asia, and Latin America. For example, in the Philippines, many women support their families by working abroad as domestics and health care providers, which allegedly fracture family dynamics of many Filipino homes. While migrant fathers supporting families is seen as par for the course, migrant mothers are blamed for the destruction of Filipino society in the media. â€Å"These reports tend to vilify migrant mothers, suggesting that their children face more profound problems than do those of migrant fathers† (Ehrenreich Hochschild, 40). In the Middle East and North Africa, the economic opportunities of women are even more restricted. Many of the popular interpretations of Islam prohibit women from working altogether, but in Egypt, women are allowed to seek employment. However, it is usually restricted to the largely unskilled service sector considered to be below the dignity of men. â€Å"This is reflected in the very low rates of wage employment in the private sector, continued high unemployment rates for educated females, and a large gender wage gap in the private sector† (Doumato Posusney, 121). In the United States, racism is still a potent force preventing the economic advancement of minority women, especially with the dismantling of affirmative action in many states. Still, those making the hiring decisions tend to be overwhelmingly white, and even though many claim to not carry racist/sexist sentiments, research has shown that they have made decisions deleterious to minority women because of stereotypes (Mutari Figart, 183).

Environmental Impact Assessment (EIA)

Environmental Impact Assessment (EIA) 1. Introduction Environmental Impact Assessment (EIA) is a procedure that requires developers to follow in order to be granted permission for a development and was first introduced in European Union (EU) in 1985 (Glasson, 1999). The guidelines and requirements of EIA come from a European Directive (85/33/EEC as amended by 97/11/EC). In this process, developer requires to compile an Environmental Statement (ES) where significant impacts and its effects on the environment as a result of a development are described including mitigation measures (Lee, 1995). However, there are weaknesses in EIA process. As a result of EIA weaknesses, Strategic Environmental Assessment (SEA) was introduced. SEA process was first introduced by EU Directive 2001/42/EC which environmental protection and sustainable development may be considered. It ensures that potential impact of proposed plans, policies and programmes on the environment are taking into consideration so that mitigation and communication between public and decision-makers are provided (Benson, 2003). Therefore, SEA is undertaken in the decision-making process of a development much earlier than EIA. In this section, the differences between EIA and SEA as well as the weaknesses of EIA that led the development of SEA in EU Directive in 2001 are being discussed. 2. Differences between EIA and SEA 2.1. Differences in provisions between SEA and EIA Directives Table 1: Summary of differences in action for EIA and SEA processes (Partidà ¡rio, 2000). SEA EIA Nature of action It is more strategic and contains visions and concepts in its action Actions towards the construction and operation level Assessment Involved evaluation Involved only assessment Focus More critical decision moments (decision windows) along with decision processes Only in project level Level of decision It involves policy and planning Only project level Relation to decision Facilitator Involved evaluator which often taking into consideration of administrative requirement Alternatives Broader and spatial balance of location, social and physical strategies, technologies and economics. More specific alternative in construction, operation, locations and design Scale of impacts Macroscopic involved local, regional, national and global Microscopic mainly involved local Scope of impacts Sustainability issues, economic and social issues may be more tangible than physical or ecological issues Environmental with a sustainability focus, physical or ecological issues, and also social and economic Time scale and review Long to medium term (after 5 years and then 7 years interval) Medium to short-term (after 5 years then silent continuing review). Key data sources State of the Environment Reports, Local Agenda 21, statistical data, policy and planning instruments Field work, sample analysis, statistical data Data Mainly descriptive and mixture with quantifiable More quantifiable Rigor of analysis (uncertainty) More uncertainty and less rigor Less uncertainty and more rigor Assessment benchmarks Sustainability benchmarks (criteria and objectives) Best practice and legal restrictions Public perception Vague/ distant More reactive Post-evaluation Other strategic actions and project planning Objective evidence in relation with construction and operation 2.2 Differences in procedural requirements of the EIA and SEA Directives. Table 2: Summary of the main differences between EIA and SEA Directives in procedural requirements ( Sources from : Sheate et al., 2005). STAGE SEA EIA Screening It requires consultation from the environmental authorities. Publicity: SEA does not need determination and reasons. It requires no consultation. Publicity: EIA requires determination and reasons. Environmental information/report Member States (MSs) have to ensure that sufficient quality and stronger emphasis on alternatives are provided in environmental reports (ERs). No quality control requires in EIA and only minimun information shoud be provided Consultation Involved relevant parties other than MSs such as public and autorities. Involved relevant parties other than MSs such as public and autorities and also consultation provision from Public Participation Directive. Decision-making All consultation comments and ER are to be taken into account. Consultation comments and environmental informations are included in decision-making. Info on decision More specific and detailed requirements. Information provision from Public Participation Directive are mademore specific in the requirement. Monitoring Long term monitoring required Not require monitoring 3. Weaknesses of Environmental Impact Assessment (EIA) 3.1. Lack of consideration of cumulative impacts EIA process is often facing difficulty in addressing cumulative impacts of a development. The significant impacts of a development especially issues on biodiversity, human health and cultural heritage are no included in their assessment (McDonald Brown 1995). For example in Scotland, several developments of wind farms proposed in close proximity have led to a very complicated EIA process (Glasson, 1999). Each developer required assessing the cumulative impact of landscape and visual application with those of neighboring projects (Benson, 2003). The planning process could face a delay due to this issue. 3.2. Insufficient public participation Public involvement has shown to be insufficient in EIA process (Gailus, 1995). In a recent research suggested that this is due to the attitude of the developer that discourages the participation of public in EIA process in the European Community. Due to lack of legislation and extensive for public involvement in Europe in the early 90s to influence the decision of a development, the general public is not aware of their rights and causes them not interested in the development involvement (Caddy, 1996). 3.3. Little monitoring and auditing process Previous study has showed that monitoring and auditing issues are still weak in EIA. Follow-up process is only performed by developers in a minority of cases (Arts and Nootebloom 1999). Monitoring process enables practioners to have better understanding for future extension, design and restoration projects (Frost, 1997). However, the river restoration process in United Kingdom (UK) was hampered by lack of monitoring process in EIA. 3.4. Inadequate consideration of alternatives The compilation of alternatives appears to be very limited in EIA report (Tesli, 2002). For example in Hungary for radioactive disposal, the report did not provide in details or rather limited in reducing the impacts of the project to the human health (Benson, 2003). It is important to include various alternatives to allow solutions being taken in a development. 3.5. The poor quality of environmental impact statements and reports The reports produced in EIA are often too complex in term of length and technical which is not easily understood by the public and decision makers (Lee, 1995). It is important for ES to be simple as it has to be made available to the public. 3.6. The timing of decisions The decision-making process in EIA project enters too late where the effects of policy and planning critical decisions are not being considered (Lee, 1995). This is due to the absence of systematic impact assessment process where the outcome of it could subsequently influence the project planning and design (Harrop Nixon 1999). 4. Conclusion There were various weaknesses have been identified in EIA process. Due to these weaknesses, SEA was developed in 2001 under EU Directive to strengthen the environmental assessment process. 5. References Arts, J. and Nootebloom, S.

Content of an SEA report as required by EU Directive The implementation of plans and programmes (PPs) in which likely significant effects produce by the project on the environment is the key requirement in preparation of an SEA report (European Parliament and Council of the European Union, 2001). Figure 1 shows the summary of the contents required by EU Directive (2001/42/EC) in producing SEA reports. Not all projects need to perform SEA process (Barth Fuder, 2002). The diagram in Figure 2 shows a set of set of criteria for application to PPs under the EU Directive (2001/42/EC). It specifies whether SEA is required or not according to the Directive. For simplicity, the developments of the PPs and reasonable alternative options of SEA are summarized in five key stages according to the government guidance in England (URL 1). 1.1. The key five stages Stage A: Context, Baseline and Scoping (SEA Directive Annex 1) Authority needs to include indicators, objectives and background information for SEA in the plan. The decisions of the scope can be decide by the authority including consultation on the statutory environmental bodies (URL 1). Stage B:Alternatives and Assessment (SEA Directive Article 5.1) Authority need to identify reasonable alternatives and assess the effects of the project on the environment. Ways of reducing, preventing and offsets the effects have to be provided as well (URL 1). Stage C: Preparing the Environmental Report Draft plan/programme which includes the information of the effects has to be presented as a key output of SEA process (URL 1). Stage D: Consultation (SEA Directive Article 6.2 and Annex 1) The draft plan and environmental report should be ready together for consultation where a statement are made from the consultation responses in order to produce an evolving plan (URL 1). Stage E: Monitoring (SEA Directive Article 10.1) The implementation of the plan where environment effects are produced needs monitoring process. It helps to provide more baseline information for future plans (URL 1). 2. Difficulties and limitations in fulfilling these requirements Table 1: Summary of the difficulties and limitations of SEA reports as required in EU Directive. Requirements issues Difficulties and limitations Availability and access to data Environmental data is often limited and not relevant because it is not collected and stored systematically. The process of data collection requires extensive resources and using these data are difficult because different departments tend to collect different set of data. The quality of good data is lacking and this issue has been reported by Member States such as Germany and Poland (European Commission, 2009). Best example of this issue is Poland. They are facing difficulties of generating and collecting data of affected area because of the implementation of a plan/programme. The current picture of the environment has to be identified especially in large areas but they indicate that it is very problematic (European Commission, 2009). Sometimes, the coverage areas of SEA are large (including few countries and produces large amount of alternatives (URL 1). This will increase the complexity of data collection and analysis (URL 1). Public Participation The availability of the data for the public is limited. In the UK, documents and information of the plan are not required to be published on their website until ER is finalized according to the draft Regulations (Partidà ¡rio, 1996). As a result, public participation is limited as not many public will travel to the plan-makers office to view the documents at a minimum time period for consultation. It is important to set up a website to facilitate the consultation process for the public to participate (Partidà ¡rio, 1996). Else, public is unaware that inspection of these documents are available to them and no feedback can be made (Kà ¸rnà ¸v Thissen, 2000). EA at higher levels of decision making As SEA involves higher levels of decision making, the implementation policy of PPs are subject to various departments decisions (Kà ¸rnà ¸v Thissen, 2000). For example, a Local Transport Plan requires policy from Regional Spatial Strategies, Aviation and Transport White Papers and Sustainable Communities Plan and Planning Policy Statements (Brown Thà ©rivel, 2000). Due to these requirements, a complex screening process has to be performed and decisions for PPS are even more very difficult in the assessment (Brown Thà ©rivel, 2000). Deciding on the level of detail of the environmental report The details of require information in SEA reports are vary due to lack of adaptation in assessment for the level of abstraction in PPs (European Commission, 2009). According to Member States (Latvia and Germany), the possible impacts of PPs are difficult to be included in SEA reports because of less information of the right scale and level required (European Commission, 2009). Therefore, important information for long term PPs is difficult as no appropriate spatial scale of information need to be included in the report (European Commission, 2009). Development of assessment methods As there are no specific guidelines, strong methodological background and lack of exchange for best practices, developing an effective assessment is very challenging (Brown Thà ©rivel, 2000). For example in Operational Programmes objectives, high level plans in a viable assessment do not necessary show the actual physical ground effects although strategic policies are implemented European Commission, 2009). Assessment of impacts Although SEA addressing the importance of cumulative impacts, there is no standard and effective assessment methodologies are being developed (Partidà ¡rio, 1996). The significant environmental impacts of PPs are difficult to assess and the identification of these aspects are limited (Partidà ¡rio, 1996). Monitoring and enforcement (Including issues of indicators) The assessment of plans is limited because there is no sustainability and environmental criteria developed in the monitoring programme (European Commission, 2009). Therefore, monitoring indicators (local agenda 21 for instance) is being used however it is difficult for monitoring process as mentioned by Member States like France. Environmental authorities have no proper enforcement tool to ensure that monitoring programme is being performed (European Commission, 2009). For example in the UK, no quality control body is being set up by the government to monitor the efficiency of monitoring process which is a limitation for SEA (Verheem, R. Tonk, J. 2000). Institutional and legal issues The supports for SEA process are still insufficient politically (European Commission, 2009). The bureaucratic prerogatives may hinder the effectiveness of SEA performance. As SEA process is relatively new, lack of human resources especially knowledgeable authorities is a major limitation for SEA (European Commission, 2009). 3. Comparison between requirement of SEA Directive (2001/42/EC) and Sustainability Appraisal (SA). In the United Kingdom (UK), SA and SEA are required in planning system and law for Government Plans and Programmes (Smith Sheate 2001). For most Development Plan Documents (DPD) and Supplementary Planning Documents (SPD), both SA and SEA process have to be carried out and include in the Local Development Framework (LDF) in the UK (Smith Sheate 2001). SA was developed to assess the likely economic, social and environmental impacts so proposed PPs can be implemented that leads to sustainable development unlike SEA which was previously described (Lee Kirkpatrick, 2000). The Planning and Compulsory Purchase Act (2004) and European Directive EC/2001/42 require both SA and SEA processes to be performed in any planning (Smith Sheate 2001). It is also requires by the Environmental Assessment Regulations for Plans and Programmes in UK (Smith Sheate 2001). In table 2, comparison of SA and SEA in terms of UK planning system for Government PPs are being summarized. Table 2: Comparison between SA and SEA requirements within the UK planning system Requirements Strategic Environmental Assessment Sustainability Appraisals Overall aims The aim of SEA is to raise the profile of environmental considerations as part of an advocative approach during decision-making process (Kà ¸rnà ¸v Thissen, 2000). In contrast to SEA, it is use as a support process in decision-making and representing an integrated approach that working towards in all aspects of sustainable development. Therefore, the interests at stake are remained neutral during this process (Minas, 2002). Focus Environmental effects (Lee Kirkpatrick, 2000) A full range of environmental, social and economic issues (Minas, 2002). Environmental/ Sustainability aspects It involves 15 components which is suggested in the 1993 guidance with additional social and economic factors to be considered in 1999 guidance (Thà ©rivel, Minas, 2002). Aspects of biodiversity, human health, cultural factors, water, landscape, population and material assets are considered primarily (Thà ©rivel, Minas, 2002). Report requirements There are no formal requirements for SA. In good practice guidance, identification of scoping and impacts stages is recommended (Thà ©rivel, Minas, 2002). The 1999 guidance also recommends that planners should provide and evaluates alternatives. Environmental baseline conditions should be considered as well. It involved extensive requirements of Annex 1 which have previously discussed (Barth Fuder, 2002). Methodology According to DETR Guide, the appraisal should emphasize on strategic options, alternatives, and policy impact matrices in achieving sustainable development. Therefore, the methodological statement is very brief if compare to SEA (Minas, 2002). In contrast to SA, heavy emphasis is in place on actually baseline data which set as a benchmark to assess the alternatives performance. It is also requires authorities to consult the final environmental report from the public on the scope of the assessment (Thà ©rivel, Minas, 2002). Timing The process is being carried out very early where every stage of the development plan process is considered as an important element (Thà ©rivel, Minas, 2002). In contrast to SA, it is usually being carried out during the preparation of a plan before the submission to the legislative procedure (Thà ©rivel, Minas, 2002). Involvement The appraisals are subjected to consultation with outside groups such as public consultation during the plan preparation. The appraisal usually made available on the internet where it is being carried out sporadically (Thà ©rivel, Minas, 2002). It is not required to make available on the internet. The consultation can be done during scoping stage by specified environmental authorities. Opportunity has to be given to the public to comment the draft plan (Partidà ¡rio, 1996). Documentation required No formal requirements according to the guidance A statement need to be produced by an authority to summarize all the considerations of the plan have been integrated. They need to provide a report of consultees opinion which taken during the consultation process and valid reasons on why the alternatives are being chosen (Partidà ¡rio, 1996). 4. Success of SEA report in delivering sustainable development objectives A wide range of processes has been integrated with SEA report. It has shown to be a systematic process where accountable decision making can be achieve due to the earlier evaluating process being taken with strong alternative visions (Wood Dejeddour, 1992). All these have incorporated in SEA policy, planning and program initiatives (PPPs) to ensure sustainable development with full integration of economic, social and political considerations (Partidà ¡rio Clarke, 2000). Although SEA shows to be a great tool in project level but the process of SEA is not easily accepted or consider as an effective solution due to its complexity (Thà ©rivel Partidà ¡rio, 2000). Recent research has shown that SEA produces both great opportunities as well as failures in sustainable development (Sadler, 1998). 4.1. Sustainability objectives are included in the integrated process of policy making and planning During the design stage of SEA, objectives of sustainability are being considered which provides a greater plan and policy in decision making (Thompson et al., 1995). It gradually delivers its objectives of sustainable development because the use of SEA articulates sustainability goals by enhancing the political action where substantive action can be taken (Partidà ¡rio, 1996). As the expectation of internal and external public of its delivery increasing, it offers the possibility of bringing better policy towards sustainable development into success. The transition of SEA involved two main steps: Information gathering and analysis work The core of strategic decision making Sustainable development consideration is being covered in a broader range where strategic level matters are separated from advisory conventionally-focused (Pezzoli, 1997). Sustainability criteria are used as the key bases to help in strategic decision making on the selection among best options available (Pezzoli, 1997). With these steps being taken, larger context of core policies and programmes in strategic assessment are identified in pursuing the objectives of national sustainability. Therefore, SEA report may be an important instrument in promoting sustainable development when it is fully integrated (Partidà ¡rio, 1996). 4.2. Operationalises sustainability principles In practical application, the concept of sustainability is very difficult because it faces high complexity and uncertain reality (Pezzoli, 1997). Interconnected generational boundaries and disciplinary of sustainability may further complicates the concept (Marsden, 1998). Therefore, the application of specific context of sustainability and commonly recognized principles are being clarified by SEA. SEA identified three key principle of sustainability: Integrated pursuit of ecological and socio-economic improvements Uncertainty imposes precautionary obligations Public choices involved SEA is a visible confirmation of commitment to sustainability as it offers broader exposure to notions such as natural capital and the precautionary principle (Pezzoli, 1997). Therefore, it can be translated into the language of politics of sustainability and functions as a heuristic device (Thà ©rivel et al., 1992). 4.3. Improves analysis of broad public purposes and alternatives With alternative technologies, lifestyle choices and better resources, SEA offers better possibility in achieving sustainable development because it has the capability to contemplating these factors that cannot be address at lower levels (Wood Dejeddour, 1992). Therefore, SEA report is the most effective and efficient point in finding alternatives and addressing the needs in pursuing the objectives of sustainability development (Thà ©rivel et al., 1992). 4.4. Facilitates proper attention to cumulative effects Strategic level proves to be the best way to deal with increasing number of cumulative impacts. The scope of SEA helps to identifying these impacts because of its space scales (Ortolano Shepherd, 1995; Scott, 1992). As SEA is performed in an early stage, this assessment allows assessors to provide more attention in a wider range of actions in a larger area. It allows them to provide a broader context of cumulative impacts in addressing each of the impacts (Thà ©rivel Partidà ¡rio 1996). According to Thà ©rivel Partidà ¡rio, undesirable activities as a results of a project can be removed before the project stage begins because these cumulative impacts have influence the project decision where SEA has incorporated environmental issues intrinsically during the planning stage. Earlier detection of these impacts helps to promote sustainable development. 4.5. Facilitates greater transparency and more effective public participation at the strategic level With the extensive involvement of public participation in SEA, it has improved the credibility and accountability of SEA in sustainability where they facilitating external scrutiny of decision (Wood Dejeddour, 1992). It creates increasing pressures in strategic decision making process to overcome bureaucratic fragmentation because in many jurisdictions, bureaucratic disorganisation and wastefulness in citizen has been declining. The expanding role of public provided in SEA allows an intrinsic connection between environmental sustainability and equity (George, 1999) to promote basic sustainability goals. 5. Conclusion There are many challenges ahead for SEA report. There are many difficulties in producing a good SEA report. Nevertheless, SEA report requirements did show success in achieving sustainable development goals. In order to ensure SEA report success, weaknesses and limitation needs to be considered and solution needed in order to overcome it. 6. References Barth, R. Fuder, A.
