Abstract

The Teaching Assistant (TA) system operating in the United States has both advantages and disadvantages to graduate students employed as TAs and undergraduates taught by these TAs. The system develops teaching and communication skills and broadens TA capability, understanding and marketability. Discussion and lab sections taught by TAs provide an arena where undergraduates are exposed to everything from simple ideas to difficult ideas that need hands‐on help. However, few quality control procedures are employed to determine prospective TAs. Moreover, TA training is of limited extent and use. TAs either sink or swim; none the less the vast majority do survive and do an excellent job. A number of measures that any university, college or department might employ if they intend to begin employing TAs are recommended: all TAs should attend TA orientation sessions that discuss university‐wide TA issues; departments should also create sessions that specially train TAs in how to teach their respective courses; and departments should develop TA evaluation schemes that quickly identify TA problems.  相似文献

As the states parties to the nuclear Non‐Proliferation Treaty (NPT) plan for the May 2010 review conference, they are faced with recurring political challenges that call into question the long‐term sustainability of the presently constituted non‐proliferation regime, notwithstanding the important role the NPT and its related institutions have played in slowing the pace of proliferation for four decades. Even if the review conference is deemed a success, its outcome is unlikely to address the regime's core structural weaknesses and normative contradictions. Frustration with the continuing status and benefits accorded to nuclear‐armed states outside as well as within the NPT, will continue to diminish confidence in the effectiveness of traditional non‐proliferation and deterrence practices. The progressive reframing of security in terms of creating a world without nuclear weapons may be little more than rhetoric for some leaders, but it has widespread public support. A growing number of governments are now expressing interest in new approaches and steps, including consideration of a nuclear weapons convention as a practical objective to work towards. The article discusses the challenges and options for the non‐proliferation regime and concludes that efforts to halt future proliferation will increasingly focus on reshaping the norms and rules to pave the way for negotiating a new nuclear security compact, based on a verified process to prohibit and eliminate the possession as well as the use of nuclear weapons.  相似文献

In order to grasp some of the key intellectual developments and trends that shaped the global politics of twentieth century and continue to shape our own world—neo-classical economics, modernization theory, deterrence theory, the democratic peace, among others—it is necessary to explore the history of the human sciences. It is important, in other words, to examine the role of the modern research university in producing and diffusing ideas about the self, society, the economy and world order. International Relations (IR), and political science more generally, played a significant role in this story. In recent years we have seen a growth of interest in the history of IR, though it is still an underdeveloped area of research. Among other things, scholars have shown that many of the foundational myths of the discipline—the views that inform textbook understandings of the past and present—are deeply flawed. This article first surveys this recent work, highlighting its strengths and weaknesses, and then proceeds to offer some thoughts on future directions for research. It identifies a range of questions and topics that have yet to be adequately addressed, and draws on the latest methodological work in intellectual history, highlighting some new interpretative approaches that can enrich scholarship in this area.  相似文献

This article considers the exceptional fate of the orphan survivorsof the great Algerian demographic crisis of the late 1860s whosubsequently converted to Catholicism. Using a prosopographicalapproach, this study seeks to highlight the complexities ofnational identity in France and to explore some of the racialtensions emerging in Algeria in the late nineteenth century.  相似文献

The changing role of Islam in the public life of Turkey is about to come under renewed scrutiny, the key issue being the potential candidates for the May 2007 presidential election. Erdoǧan, the Prime Minister and head of the first Islamist majority government in the republic's history, is likely to stand. Arguments already abound as to the legitimacy of such a move, with the opposition declaring that they will boycott the election if Erdoǧan becomes a candidate. Equally, Erdoǧan's own supporters are, in public, at least occasionally uncertain, conscious that when the late Özal moved to become president, his party suffered. Secularists grimly wonder whether they will be able to survive such an overt transfer to an Islamist figure, one whom they fear would be a great contrast to the pro‐Republican present incumbent, President Sezer. Yet, how should we face such a transition? What implications does it have for Turkey's politics, both internally in terms of the social life of the country, and in external affairs?  相似文献

Utilising recent observations by Phillips (2003) on the location of chambered cairns in Orkney in relation to the sea this paper attempts to explain why megalithic monuments cluster in particular locations. In the past, the distribution of cairns has been related to the levels of survival in marginal locations. However, monument locations, from across Scotland, demonstrate that clustering was a feature of monumental distribution in the past. From a maritime perspective it becomes easier to understand these groupings in Orkney as the product of interactions between widely dispersed island communities. Utilising a long-term perspective it is possible to use the relative patterning of monuments of different ages to suggest the changing audiences to whom these monuments were addressed. For example, the clustering of Earlier Neolithic monuments in Orkney, in places that form important linking locales, suggests a role for these monuments involving establishing and maintaining links between island groups within the Orkney archipelago. The location of later Neolithic monumental complexes, on the other hand, suggests the importance of inter-regional maritime contact at precisely the time when such contacts are strikingly evident in the archaeological record. It is argued that a closer integration of our approaches to land and sea is needed if we are to understand the nature of long distance contacts in the past.

Pakistan's status as a nuclear power, which was made manifest when it carried out six nuclear tests in May 1998, came under renewed international scrutiny following the terrorist attacks on the United States in September 2001. Of most immediate concern was the security of Pakistan's nuclear arsenal, which was believed to be vulnerable to Muslim terrorist groups with close links to the al-Qaida organization, headed by Osama bin Laden. However, the international crisis centering on the 'war against terrorism' is bound to revive debate about Pakistan's involvement in the nuclear non-proliferation regime; the risks of a nuclear war between India and Pakistan over Kashmir; and the need for tighter curbs on the export of nuclear technology to politically volatile regions in the Muslim world. These debates are likely to be overshadowed by Pakistan's own perceptions of the danger it faces of a military threat from a nuclear-capable India; its aspirations as a regional power; and its desire to be recognized as 'first among equals' in the Muslim world community of nations. Any attempt to draw Pakistan into the non-proliferation regime and to persuade it to assume its responsibilities as a nuclear power will need to address these concerns. Ultimately, however, it will be for Pakistanis to decide how long they wish to subordinate their country's economic well being to the pursuit of a nuclear programme whose priorities are defined by an unaccountable military regime.  相似文献

The Byzantine silk industry played a major role in the history of the Byzantine Empire. Silk, a key economic asset, had strong political overtones, and the effects of its multiple influences were felt far and wide, both within Byzantium and abroad. This article highlights some of the difficulties encountered in the interpretation of important documentation surrounding the Byzantine silk industry in the period up to 1204 A.D.  相似文献
