An Electric Battle A WebQuest for War of the Currents Introduction At the turn of the twentieth century, the War of the Currents had a clear winner—Tesla and his alternating current. However, direct current survived into the twenty-first century. As recently as 2007, some parts of Manhattan were finally converted to alternating current. The transition from direct current to alternating current begin in the late 1920s but took decades, in part, because the foundation of New York City’s energy grid was build by Edison’s company. Task Your task is to research the everyday devices credited to Edison and Tesla. You will compare these inventor’s influences by creating a script for a 5-min mock “debate” between Edison and Tesla in which they debate their influences on today’s and future technology. Process Use the resources listed in the Resources section to begin your research. The Web sites listed are good starting points, but further Internet research will be necessary. Record your answers to the following questions. 1. What was the relationship between Tesla and Edison prior to the War of the Currents? 2. Both Tesla and Edison were prolific inventors. If the two were competing to obtain the most number of patents filed, who wins and by what margin? 3. Did any of Tesla’s or Edison’s inventions build upon one another or work together to bring about new technology? 4. Could direct current make a comeback? Explain your answer. Write a Script Write a script for a 5-min mock debate between Edison and Tesla, in which each tries to convince the audience that he was the more influential inventor. To support their arguments, Edison and Tesla should provide multiple examples of the everyday devices that are the result of their inventions.

War of Currents
War of Currents In the War of Currents era (sometimes, War of the Currents or Battle of Currents) in the late 1880s, George Westinghouse and Thomas Edison became adversaries due to Edison's promotion of direct current (DC) for electric power distribution over alternating current (AC). Edison's direct-current system generated and distributed electric power at the same voltage as used by the customer's lamps and motors. This meant that the current in transmission was relatively large, and so heavy conductors were required and transmission distances were limited, to about a mile (kilometre); otherwise transmission losses would make the system uneconomical. At the time, no method was practical for changing voltages of DC power. The invention of an efficient transformer allowed high voltage to be used for AC transmission. An AC generating plant could then serve customers at a great distance (tens to hundreds of miles), or could serve more customers within its economical transmission distance. The fewer much larger plants needed for AC would achieve an economy of scale that would lower costs further. The invention of a practical AC motor increased the usefulness of alternating current for powering machinery. Edison's company had invested heavily in DC technology and was vigorously defending its DC based patents. George Westinghouse saw AC as a way to get into the business with his own patented competing system and set up the Westinghouse Electric Company to design and build it. The Westinghouse company also purchased the patents for alternating current devices from inventors in Europe and licensed patents from Nikola Tesla.

Government Regulations of Shechita (Jewish Religious Slaughter) in the Twenty-First Century: Are They Ethical?
J Agric Environ Ethics (2012) 25:747–763 DOI 10.1007/s10806-011-9324-4 ARTICLES Government Regulations of Shechita (Jewish Religious Slaughter) in the Twenty-First Century: Are They Ethical? Ari Z. Zivotofsky Accepted: 1 July 2011 / Published online: 15 July 2011 Ó Springer Science+Business Media B.V. 2011 Abstract Human beings have engaged in animal husbandry and have slaughtered animals for food for thousands of years. During the majority of that time most societies had no animal welfare regulations that governed the care or slaughter of animals. Judaism is a notable exception in that from its earliest days it has included such rules. Among the Jewish dietary laws is a prohibition to consume meat from an animal that dies in any manner other than through the rigorously deﬁned method of slaughter known as shechita. In recent decades more and more attempts have been initiated by governments around the world to either outright ban or to control and modify the practice of shechita. This paper presents the requisite background about shechita and then analyzes the ethics of some of the recent legislation. The analysis includes a rebuttal of the assertion that shechita is an inhumane method of slaughter. It further presents the consequences on the Jewish community of legislation to impose pre-slaughter stunning and explains why such legislation is unethical. The actual effect of labeling laws is discussed and it is shown why such laws are also un- ethical. Keywords Animal welfare Á Ethics Á Government regulations Á Religious slaughter Á Shechita Introduction Human beings have historically maintained animals for food production, labor, and companionship.

The laws derive from the oral law, stemming from the prohibition to eat the flesh of live animals, in combination with the general Biblical obligation for humane treatment of animals. The first part of this paper is an exposition of the origins of shehitah, and the laws for correctly carrying out the process. The second part of this paper addresses the history of the practice of these laws in select European countries and the United States. This history includes a discussion of anti-shehitah campaigns and legislation through modern times. 2 Table of Contents Abstract ................................................................................................................................ 2 Part I: The Laws of Shehitah ..............................................................................................

Kosher Slaughter, State Regulation of Religious Organizations, and the European Court of Human Rights
4-18 COHEN 06-12-09.DOC 6/15/2009 6:03 PM KOSHER SLAUGHTER, STATE REGULATION OF RELIGIOUS ORGANIZATIONS, AND THE EUROPEAN COURT OF HUMAN RIGHTS JONATHAN COHEN I. Introduction On May 6, 2009, the European Parliament passed a legislative resolution regarding the regulation of animal slaughter in the European Union. The resolution addressed a proposal made by the European Commission in September 2008. The Commission’s proposal had also been referred to the European Economic and Social Committee (EESC), and the latter produced an opinion in its regard on February 25, 2009. The European Parliament’s new resolution is an important milestone in the European debate surrounding the slaughter of animals in general and the regulation of ritual slaughter in particular. Against the background of this resolution, we may now assess the unfolding of recent developments in the debate over ritual slaughter in Europe, and highlight a number of issues that have recently been afforded little attention. To begin, we note that kosher and halal (Muslim) slaughter methods have been allowed by European Union rules, and that the exemption from stunning animals prior to slaughter has been tolerated at the European level.1 A study that was commissioned by LL.B.; Ph.D. Associate Professor in Talmud and Halakhic Literature, Hebrew Union College-Jewish Institute of Religion, Cincinnati; Director, Hebrew Union College-University of Cincinnati Center for the Study of Ethics and Contemporary Moral Problems. 1 The issue of stunning is briefly addressed below. The first European directive on the issue of animal slaughter was enacted in 1974 (74/577/EEC).
