Why Political Polarization Has Gone Wild Example

Why Political Polarization Has Gone Wild Example Why Political Polarization Has Gone Wild †Coursework Example Notice July 25, Daily Editor RE: Political Polarization in the Media Polarization from the two sides of the political range has arrived at what some accept is a minimum amount of firm idealists. Fareed Zakaria refers to various models present both in the legislature and among activitists that help the perception of expanding polarization among nonconformists and conservatives1.One of these models is non-factional redistricting, which is a hypothesis that if locale in the House are changed to such an extent that each gathering has safe seats, there will be less polarization between the gatherings on Capitol Hill. Shockingly, political polarization happens moreso on radio waves and around lobby meetings.One may contend that we should all be disillusioned without government officials for pandering, at the end of the day, in a majority rule government, our legislators are delegates of the individuals. It isn't the lawmakers who cause their supporters to be increasingly extraordinary; rat her, it is the opposite way around. There is a motivation behind why the individuals who choose Congressmen to their seats are called â€Å"the base.†Without 24-hour media, there would not be such an outrageous reaction to certain arrangement conversations and, thus, our government officials would not be headed to such extraordinary talk on the House floor, in the event that they realized nobody was focusing. In any case, a consistent consideration regarding the exercises and belief systems of our legislators energizes them, out of a longing to keep their occupations, to pander to their base.The media, including papers, assume a key job in this. By concentrating exclusively on the outrageous components so as to keep individuals perusing and viewing, the media channels a shopper interest for captivated governmental issues: a drama happening on the nightly news. This is the thing that Fareed Zakaria alludes to as â€Å"narrowcast†. Certain radio projects and news systems come to be perused uniquely by people with specific ideological demeanors. Rather than engaging a general crowd with target data, media turns data such that they can sell the best.So, how does a media establishment like a paper assume a job in fixing too much ill-disposed governmental issues? It can begin by taking the realities of the real world and introducing them to the entire world in a goal and socially dependable way. As opposed to concentrating on the little shows of political discussions, a paper can introduce the entire picture and permit its perusers to choose. The media assumes an essential job in keeping voters educated in our majority rules system. On the off chance that the media defaults on its duty, at that point our arrangement of administration won't be a long ways behind.

The Issue And Action Of Drugs - 941 Words

War on drugs has been an issue in the United States for several years now. Being a college student at East Carolina University, I have met several people in the community and have witnessed a lot. As I continued to grow as an adult at East Carolina, I began to fully understand how serious of a problem drugs were. People see doing drugs as a way to fit in with others, using it for social purposes. After having friends go to the hospital or sadly, die from an overdose on drugs, I have decided to take action myself. It seems that the majority of the people today do not want to fully understand the consequences that come from drugs. Yes, they feel sympathy for those who have passed away from overdose or mixing drugs with other drugs but do not seem to change their ways any. We first as a community need to understand and accept the fact that drugs are a serious issue and action needs to take place. The solution to preventing people from getting their hands into addictive drugs and becoming addicted to them is for our community and law enforcement to collaborate and start a prevention agency. Firstly, it all starts with the children and I believe we should start trying to find a way to keep drugs away from them.

Learning Is Viewed As One Of The Most Important...

Learning Theory Paper Kimberlyn Boddie EDUC 2130: Teaching Learning Professor: George Darden November 1, 2015 Learning is viewed as one of the most important interactive activities in which children engage. Although most learning occurs outside of the school setting, it is the heart of the educational process. Psychologists and philosophers searched to understand the true nature of learning, why and how learning occurs at different stages in life and how it can have an influence through teaching methods and similar endeavors. For many years, various learning theories have been listed as suggestions and these theories differ with understandable reasons. Whether theories are based on scientific evidence or†¦show more content†¦As a child, Dewey excelled as a student in public schools, then went on to study philosophy; graduating second in his class. While teaching at the universities, Dewey became fascinated with philosophical treatises and decided to expand focus in studying psychology and philosophy at John Hopkins. Although Dewey’s philosophical treatises were inspired by William James; George Sylvester Morris (American educator and philosopher) and G. Stanley Hall (American educator and psychologist) were among some of the the most influential philosophers in Dewey’s life. John Dewey and education- his ideas embodied the philosophy of pragmatism. His philosophy is known as instrumentalism, experimentalism and focus on the human experience; abandoning previous rigid exposure of transcendentalism through academia. He believed behavior is out of habit and change will produce unexpected outcomes. By creatively thinking, one can resume control of a shifting environment and through those thoughts, a connection with the real world is formed. A universal education is the best practice for teaching abandonment of habits and think creatively. Dewey’s approach to learning is that of hands-on learning, oppose to conforming to a lectured approach., education should stem from the principle of learning

Visa Compliance - Cancellation and Review - myassignmenthelp.com

Question: Discuss about theVisa Compliance, Cancellation and Review for Immigration. Answer: Singh v Minister for Immigration Anor [2017] FCCA 1901 (14 August 2017) In this case, the appellant held a student (Temporary) (Class TU) Subclass 573 visa while he arrived in Australia and had undertaken an English Language Intensive Course for Overseas Students (ELICOS course). However, he had difficulties with the ELICOS course and was subjected to depression. The appellant had submitted a written statement before the Tribunal stating the reasons why he changed his study course to cooking as he always wanted to become a professional cook. Since the appellant came from India he believes there are several scopes for his future employment as a professional cook. The Federal Circuit Court contended that Tribunals decision did not include the material that the applicant had provided to the court through his statement regarding his reasons to change his study course to cookery from business management. An administrative tribunal is saifd to commit jurisdictional error when it fails to consider matters which is required to be considered by the court. Under section 499 of the Migration Act 1958 (Cth) and Direction No. 53, the tribunal is required to take into consideration those materials that are laid down in the Ministerial Direction No. 53 that is relevant to the decision[1]. The tribunal was held to have misconstrued the evidence that was produced before it by the appellant. It failed to have regard to the essential documents regarding his reasons for changing his study course and his reasons for depression. This amounted to a jurisdictional error on part of the Tribunal for failing to consider the relevant material. The Tribunal held that the depression of te appellant was a result of the considerable gaps that was present in the enrolment and studies of the applicant. The Tribunal further held that as per the subsequent analysis of the claims made by the Appellant it is because of the gaps in the studies and enrolment that caused his depression. The tribunal had failed to consider the actual diagnosis that the appellant had referred to which is evident that the appellant was feeling depressed as he wished to change his study course from management to cookery and he misses his parents who resides in India and he is away from home. The appellant visited Dr Tahayvalappil-Kyparath and the diagnosis was conducted by the same doctor. The court failed to consider the diagnosis report while making its decision. The Tribunal failed to notice the diagnosis as a result of which the claim made by the applicant regarding his reason for depression was rejected by the Tribunal. The tribunal rejected the fact that the appellant was suffering from depression as he was away from home for a significant time without any educational achievements and a considerable gap in his study have resulted in his mood swings[2]. The tribunal had taken a brief and insignificant part of the oral evidence adduced by the applicant with respect to his enrolment in the Hospitality course which was completely irrelevant to the any of the matters that were mentioned in students written statement. The Tribunal had overlooked the reasons and considered the depression to be the result of the gaps in the appellants enrolment. The Tribunal restricted its consideration by stating that there is no relevancy between the applicantss previously completed education and his recourse to management studies. The Tribunal has not only failed to have regard to the essential matters that were to be taken in to consideration as per Direction No. 53 but also failed to mention that it is permitted to make reasonable changes to study or career pathways which was also stipulated under Direction No. 53[3]. The decision made by the Tribunal with respect to the consideration of the Applicants claim and materials , it is evident that it lacked essential distinctiveness which establishes that the Tribunal had failed to have regard to the essential material that was required to be considered. The ignorance of relevant matters such as the diagnosis of depression and the evidence in the form of written statement which includes reasons of the applicant to change his study course, is a clear evidence of the fact that the Tribunal had failed to exercise its jurisdiction for which it was authorized.

Microgrid Essay Example

Microgrid Essay Modelling and Simulation of Microgrid Application at RCET Rana A. Jabbar1, Azah Mohamed2, Muhammad Junaid1, Muhammad Ashraf1, Ihsan Ullah1 1Rachna College of Engineering and Technology, Gujranwala, Pakistan 2Universiti Kebangsaan Malaysia (UKM) [emailprotected] edu. pk ABSTRACT Renewable energy resources have got vital importance in present era as fossil fuel reserves are depleting and their prices are fluctuating drastically. The role of these resources in generation of electricity is inevitable in the developing countries like Pakistan, where energy crisis has become a burning issue due to short fall of electricity. Presently the country is suffering from repeated and shocking black outs. Therefore, the generation of electricity through other than traditional resources has become indispensable. In this research paper an innovative concept has been imparted for the development of Microgrid, based upon locally available renewable energy resources, keeping in view the geographical location of Rachna College of Engineering Technology (RCET), Gujranwala-Pakistan. These available renewable energy resources have been integrated to function as a single generating unit for forming Microgrid. The comprehensive modelling and simulation of Microgrid has been performed using MATLAB. The objective behind the development of this proto type model of Microgrid is to design a standby power for RCET Library in case of electricity failure from National Grid. Alternative Energy Development Board (AEDB) of Pakistan is looking for viable solution to compensate the National Grid and emergency need of individual sensitive consumers since long. Simulation and implementation of this developed model will really be very helpful for all stake holders of power industry nationally and internationally.

Introduction Microgrid is actually assembly of renewable energy resources able to be operational paralleled or independently from National Grid having capacity up-to Distributed Generation (DG). Microgrid is more modern way for utilizing the available potential of DG, not only in remote area electricity development but also in over coming the short-fall of electricity commercially. Most commonly available renewable energy resources, used for the development of Microgrid, are Solar, Biomass, Micro-hydro, Wind, Fuel Cell etc [1, 2, 3, 4]. Like other developing countries, Pakistan is also suffering from acute energy crisis. The present sources for generation of electricity in Pakistan include Hydro (33%), Natural Gas (35. 7%), Oil (28. 7%), Coal (0. 3%) and Nuclear (2. 3%). Despite the massive availability of renewable energy resources, their contribution towards generation of electricity in Pakistan is negligible. The Maximum demand of electricity in Pakistan is about 15,000 MW, whereas supply demand gap is about 3000 – 4000 MW. The renewable resources used in this research work are Solar, Biomass, Micro-hydro and Fuel Cell. Pakistan located in the Sun Belt is ideal for taking advantage of solar energy. The mean global irradiation falling on horizontal surface is about 200–250 watt/ m2 per day, equivalent to about 1500–3000 sun shine hours and 1. 9 – 2. 3 MWh/ m2 annually [5]. Being an agriculture country, sufficient live stock is available for producing enough animal dung to be utilized in the production of biogas. Following the latest statistical data of AEDB, the available micro-hydro potential in Pakistan is about 2000 MW. Moreover, there is an immense potential to utilize the flow of water in world’s largest canal network, particularly in province of Punjab, Pk [6]. This paper presents a novel approach of Microgrid development in which micro-level energy generation resources are first incorporated with each other to form one generating station controlled by a central unit and simultaneously integrated with National Grid for both way power flow [7]. Conventionally, these DG resources are not integrated with each other and separately run the load, controlled by individual switches [8, 9, 10, 11, 12]. The power quality issues involved during the conversion from dc source to ac for Microgrid operation have become the subject of research. Moreover, the study of intelligent control for Microgrid is also in progress [13, 14, 15]. In this research paper, the single control unit is responsible for overall functioning of the developed model of Microgrid supported by the physical location of RCET Grw, Pk, where a Marala Nokhar Link Canal flows adjacent to the college. The complete simulation of Microgrid has been performed using MATLAB Simulink for supplying power to RCET library. 2. Geographical Location of RCET Fig. shows the geographical location of RCET indicating the renewable energy resources and library (load). Fig. 1. Geographical location of RCET Detail of Library load (8 kW) is given in Table I.

[pic] Fig. 2. Single line diagram of RCET power distribution network 3. Real Models of Renewable Energy Resources at RCET The project for Microgrid development at RCET is divided into two main phases: Firstly, modelling and simulation of Microgrid and secondly, implementation of simulated model practically. For this purpose, three real models have been focused at RCET. Fig. shows the practical Biomass arrangement to produce methane gas (CH4) used directly as input to Fuel Cell or the same methane gas can be decomposed to get hydrogen. In this research work hydrogen Fuel Cell is used for simulation purpose. Fig. 3. Biomass plant at RCET Fig. 4 is indicating the PV Array which is available at RCET for solar energy generation. [pic] Fig. 4. PV Array Fig. 5 is showing the Micro-hydro resource which will be utilized for generation of electricity through Microgrid while implementing the simulated model. [pic] Fig. 5. View of Nokhar Canal flowing adjacent to RCET 4. Block diagram of Proposed Microgrid Block diagram of proposed Microgrid is given in Fig. 6. Fig. 6. Block diagram of Microgrid PV Array and Fuel Cell are dc sources where the Micro-hydro is an ac source of power supply. So, for synchronization the both afore mentioned resources will also be converted in ac supply. Two methods are used to convert the dc sources into ac supply. First is the Pulse Width Modulator (PWM) inverter to convert dc supply into ac supply. The second method is the use of Motor-Generator set, in which dc motor is run by dc supply and then that motor will be used as prime mover for generator to provide ac output at the terminals of generator. Their results are also compared in this research work. Moreover, this combined generating unit of Microgrid is also integrated with National grid for both way flow of power. Whenever the generation exceeds the load requirement, the extra power will be supplied to distribution network of National grid, otherwise it will be supplied by National grid 5. Modelling and Simulation Comprehensive modelling and simulation of Microgrid to run 8 kW load of RCET Library has been performed using MATLAB software. The detail of mentioned software used for simulation is as under: MATLAB  ®, the Language of Technical Computing Version: 7. 6. . 324 (R 2008a), February 10, 2008 License Number: 161051 Fig. 7 shows the Interconnected Microgrid in which all the three renewable energy resources are connected to run the Library load. Moreover, this generating unit is further interconnected with Power distribution system (National Grid) for both way power supply. [pic] Fig. 7. Microgrid Simulation Model Br ief description of resources (PV Array, Fuel Cell and Micro-hydro) used in simulation is as under: 5. 1. PV Array For simulation purpose, PV Array is replaced with a 12 v dc battery, which is boosted up by use of DC/DC Boost Converter up to 320 v dc as shown in Fig. . [pic] Fig. 8. DC Battery DC/DC Boost Converter Fig. 9 is indicating the PWM operation, to convert 320 v dc supply into 400 v ac. [pic] Fig. 9. PV Array Simulation Model using PWM Inverter The above simulation is also performed using Motor-Generator set. Fig. 10 is the Simulink model for PV Array based ac supply generating unit in which Motor-Generator set is used for dc to ac conversion. Output of PV Array is 12 v dc which is boosted up to 240 v dc using DC/DC Boost Converter to run the dc motor. [pic] Fig. 10. PV Array Simulation Model using Motor-Generator Set 5. 2. Fuel Cell Fuel Cell is also dc generation source like PV Array. Here dc is again required to convert into ac supply for integration among the renewable energy resources and also with National grid. For this purpose both PWM Inverter technique as well as the Motor-generator set are used. Fig. 11 shows the hydrogen Fuel Cell in which dc supply is boosted up through DC/DC Boost Converter and after that the same mechanism of PV Array, as shown Fig. 9, is used to convert up to the required ac voltage level [pic] Fig. 11. Hydrogen Fuel Cell Fig. 12 shows the internal model of Motor-Generator set for dc to ac conversion used in Fuel cell. pic] Fig. 12. Fuel Cell Simulation using Motor-Generator set PWM inverter is commonly used for dc to ac conversion. However, Motor-Generator set has also been practiced during this research work. Due to certain inherited characteristics, like increase in technical losses, vibration at starting etc, PMW is preferred considering operational and economic comparison. 5. 3. Micro-hydro Micro-hydro is an ac source of power supply. For simulation purpose, Micro-hydro is replaced with a synchronous generator. Fig. 13 indicates the internal model of Micro-hydro. [pic] Fig. 13. Micro-hydro simulation structure 6. Comparison of PWM and Motor-Generator Set output In the following sections, comprehensive comparison of PWM and Motor-Generator set techniques is given graphically along with tabular form. This comparison reveals that the latter mechanism is suffering from unavoidable fluctuation initially, resulting in undue operational and economic constrains. Keeping in view the above scenario, PWM technique is more advantageous. 6. 1. PWM Inverter The results for PV Array obtained in result of simulation performed using Fig. 7 are given in Fig. 14. Fig. 14. PV Array output Vinv shows the 320 v ac PWM output. VLoad is the desired level of voltage that appears at the load terminals. PL is the Library load. During time interval (0–0. 4) sec, PV Array shares 2. 67 kW (out of 8 kW) of Library load and rest of the 3. 3 kW is supplied to National grid. From (0. 4–1. 0) sec PV Array is supplying total generating power (6 kW) to National Grid. The results for Fuel Cell got in result of simulation performed using Fig. 7 are given in Fig. 15. [pic] Fig. 15. Fuel Cell results During time interval (0–0. 4) sec Fuel Cell shares 2. 7 kW of Library load and supplies 3. 3 kW to National Grid. From (0. 4–0. 7) sec it shares 4 kW of Library load. From (0. 7–1. 0) sec it provides total generated power (6kW) to National Grid. Following the previous pattern, results regarding Micro-hydro are shown in Fig. 16. Fig. 16. Micro-hydro output During time interval (0–0. 4) sec Micro-hydro shares 2. 67 kW of Library load. From (0. 4–0. 7) sec it shares 4 kW and from (0. 7–1. 0) sec it provides all 6 kW to Library Load and reaming 2 kW are contributed from National Grid. The previous results are summarized in Table II: TABLE II Microgrid Power Flow using PWM Inverter |Time |PV Array (kW) |Fuel Cell (kW) |Micro-hydro ( kW) | |Interval | | | | | |PL |Psys |PL |Psys |PL |Psys | |(0–0. 4) sec|2. 67 |-3. 30 |2. 67 |-3. 30 |2. 67 |-3. 30 | |(0. 4 –0. 7) |0 |-6. 0 |4. 0 |-2. 0 |4. 0 |-2. 0 | |sec | | | | | | | |(0. 7 – 1. 0)|0 |-6. 0 |0 |-6. 0 |6. |2. 0 | |sec | | | | | | | 6. 2. Motor-Generator Set Simulation referring to Fig. 7 using dc Motor-Generator set in comparison with PWM inverter is described graphically in this section. Results are also summarized in tabular form. Figs. 17, 18 and 19 are the graphical results of PV Array, Fuel Cell and Micro-hydro respectively using Motor-Generator set for dc to ac conversion where required. Results discussed earlier indicate the initial fluctuation in case of Motor-Generator set is prominent. Fig. 17. PV Array output (Motor-Generator Set) [pic] Fig. 18.

Islanding with National Grid To cope with the contingencies, islanding of the simulated Microgrid with National grid is shown in Figs. 20 and 21 respectively. [pic] Fig. 20. Islanding with National Grid pic] Fig. 21. Internal Structure of Fig. 20 It is clear from Fig. 21 that Microgrid is running 6 kW load. At time 0. 3 sec, 1. 5 kW is added with the system, and at 0. 5 sec another 2 kW is connected wit h the system and at 0. 7 sec additional 2. 5 kW load is connected with the system. Now total load connected to Microgrid (interconnected with National grid) is 12 kW, where 6 kW is shared by Microgrid while remaining 6 kW is supported by National Grid. Fig. 21 shows the results measured by scope in which at time interval 1 sec. the breaker of National Grid is open. The purpose behind this is to produce an artificial over current fault when all the 12 kW load is supposed to be shared by Microgrid, resulting in voltage drop at output terminals of Microgrid. During this operation, the over current and under voltage relays will be operated and consequently additional 6 kW load will be disconnected as indicated in Fig. 21(the position of breaker went to ‘0’ at time 1. 0 sec). [pic] Fig. 21. Islanding results The islanding operating is summarized in table IV as: TABLE IV Islanding operation |Time |Load Shared by|Load Shared by |Breaker |Total Load | Interval |Microgrid |National grid |Position | | |(sec) | | | | | |0 – 0. 3 |6. 0 kW |0 kW |ON (1) |6. 0 kW | |At 0. 3 |6. 0 kW |1. 5 kW |ON (1) |7. 5 kW | |At 0. 5 |6. 0 kW |3. 5 kW |ON (1) |9. 5 kW | |At 0. 7 |6. 0 kW |6 kW |ON (1) |12. 0 kW | |At 1. 0 |12. 0 kW |0 |OFF (0) |12. 0 kW | |1. 0 (Relay |6. 0 kW |0 |OFF (0) |6. kW | |operates) | | | | | 8. Conclusions This novel approach comprising of locally available renewable energy resources and integration of these resources for up-gradation to commercial use will really help the National Electric Power Regulatory Authority (NEPRA), Alternative Energy Development Board (AEDB) and Pakistan Electric Power Company (PEPCO) to set their directions while planning about generation of electricity from renewable energy resources to minimize huge gap between demand and supply. Comparing traditional and latest instrumental techniques is really interesting during this research work. Innovative model developed will also help the scientific community at national and international level. For further investigations like the influence of the factors influencing power quality issues is in progress. References [1] Robert H.
