Empowering backbench Members of Parliament in order to restore the effectiveness of the House of Commons has been a central theme in Canadian parliamentary reform for at least fifty years, but results are widely seen as disappointing. This article argues that unrealistic expectations, fostered by adherence to a traditional conception of the Westminster model of representative and responsible government, are part of the problem. A modernized conception of parliamentary government, recognizing the House as a forum for competing political parties between elections, could help us to better understand the House and improve its contribution to democratic governance. The proposed approach suggests innovative procedural options for legislative debate, Question Period, and other activities. It also offers a consistent basis for addressing issues such as floor-crossing, coalitions, and prorogations. More broadly, it points to the need for an integrated approach to the House, elections, political parties, public education, and citizen engagement in order to respond to contemporary democratic challenges.  相似文献

ABSTRACT

During its assault on Nanjing, the Japanese Army bombarded and sank the USS Panay, an American gunship, straining the relations between Japan and the United States. During the Nanjing Massacre, to ease tensions with the United States, Japan allowed the staff of the American embassy in Nanjing to make an early return to the city. While investigating allegations that Japanese troops had trespassed on American property and kidnapped and raped a Chinese woman, the American diplomat John M. Allison was struck in the face by a Japanese soldier. The U.S. government exerted pressure on Japan over what was referred to as the “Allison Incident”: under orders from Tokyo, the Japanese occupying force in Nanjing apologized to Allison and placed the officers and soldiers involved in the incident under court-martial. The incident was thereby resolved. However, amidst the furor of the “Allison Incident,” the Chinese woman who had been assaulted was forgotten by both the American and Japanese governments as well as by public opinion. The Japanese soldiers were placed under court-martial not for raping the Chinese woman, but rather for striking an American diplomat. The U.S. government received a great many reports on the atrocities committed by the Japanese Army, but in policy and deed, the American response was limited to safeguarding its national interests in China.  相似文献

Does the emergence of a new boundary‐spanning policy regime shift the focus of well‐established organized interests, or does it mobilize new ones? In this article, I show that interest groups with a presence in Washington before 9/11 rapidly—but temporarily—shift their attention to the homeland security issues. Established groups' entrenchment in antecedent subsystems appears to buffer against widespread policy disruption and interest upheaval. However, a new set of previously latent groups opportunistically mobilizes after the regime is institutionalized. Newly mobilized groups replace those that retreat back to the regime's antecedent subsystems. Though the policy regime fails to resolve the jurisdictional turf conflicts that triggered its creation, the institutionalization of homeland security generates its own original, distinct government demand for lobbying. Interests that previously had no business in Washington before 9/11 took advantage of the new opportunities the regime offered without supplanting interests established long before the Department of Homeland Security and its congressional committees existed.  相似文献

Archaeological research in central‐northern Patagonia (Atlantic coast and lower the valley of Chubut river) showed that this area was used since at least the Middle Holocene. Stable isotope analyses (13C and 15N) of human bone samples indicate that hunter‐gatherers living in that area had a terrestrial‐marine diet including guanaco meat, land plants, mollusks and pinnipeds. Despite this general trend, intersite variability and changes through time were noted, especially after the late Holocene. These results have been reinforced by archaeofaunal, technological and bioarchaeological records. In this paper, three hypotheses are examined: (a) the diet of these populations was complete and rich enough to ensure good health status and avoid nutritional deficiencies; (b) carbohydrate consumption increased progressively after 1000 BP, when pottery technology was adopted and (c) this kind of mixed diet would have been qualitatively more nutritious than that of other populations of the region, which would have resulted in better nutritional and healthy conditions. These three hypotheses are compared with dental results obtained from 563 permanent teeth from 45 individuals (34 adults and 11 juveniles from both sexes), rescued from burial sites. Indicators of oral health were assessed through the observation of caries, abscesses, wear, pulpar cavity exposure and ante mortem loss. Features of nutritional status such as enamel hypoplasia, porotic hyperostosis and cribra orbitalia were also examined. Given the availability of direct radiocarbon dating for most of the sample, three temporal series were determined: ‘Before 1000 BP’, ‘1000–5000 BP’ and ‘Post‐contact’. No evidence of alimentary stress or iron deficiency was found in individuals from the three series, which accounts for healthy and good nutritional life conditions. After 1000 BP, the results show a progressive increase in the caries percentage and a decrease in abscesses, dental wear and ante mortem losses frequency. This is possibly related to more consumption of processed foods in the last 1000 years. These results were compared with similar studies based on samples from different environments and latitudes of Patagonia. Evidence suggests that mixed diets (marine‐terrestrial) would have been more appropriate and nutritionally complete than exclusively marine or terrestrial diets.

魏晋南朝地方军政官的频繁变乱是个值得研究的问题。其原因主要在于:军府长官在获得财富方面具有先天之利,名义上属于国家的地方财富常常会被越轨的军政长官挪作私用。当时以“节”为发兵符信,但是诏书与尚书符都很容易被伪造,朝廷无法防止地方军政官擅自募兵、兴兵。中央也曾对军府内部士兵、府僚、属州刺史与军府长官之间过于亲密的关系进行干预,并且加以种种规定。但这些规定具有矛盾性,而且这种矛盾性又总是向有利于军府长官的方向转化。中央一直向军府派驻有各种监察性质的官员,但这种官员在身份和地位上又从属于府主,有听命于府主的义务。  相似文献

世界历史在18世纪出现了罕见的“共时现象”,其中最明显的就是政府职能的扩展。但在中国,相比之下这段历史却不太为人注意。本文力图展示乾隆初年清代政府在劝农、兴修水利和开矿几个方面的所作所为。如果说,在18 世纪的西欧,政府职能扩展已属于一种“现代现象”,那么我们又应如何看待中国的这段历史?  相似文献

A senior World Bank economist presents a study focusing on issues controlling Russia's accession to the WTO in 2007. The paper discusses the principal reform commitments that Russia has made in an effort to become a member of the organization and addresses the question of whether the country faces excessive demands due to political considerations. While exploring such issues as potential relations with foreign exporters and investors, the author summarizes the relevant parts of his recent joint study of Russian import tariffs that casts a new light on a complex aspect of international trade. Among other problems relating to Russia's entry, he discusses in some detail branch banking and the tradedistorting subsidies in agriculture.

Two China-based geographers examine the gradual relaxation of restrictions on the activity of foreign banks in China as a prelude to a more focused investigation of the concentrated locational pattern of foreign banking in that country. The study, which embraces 32 Chinese cities, emphasizes the factors that have attracted foreign banks to particular cities and regions of China, including the existence of special banking opportunities, the so-called "follow-the customer" strategy, externalities associated with major financial centers such as Beijing and Shanghai, relaxed banking regimes in particular urban centers and special economic zones, and exposure to international trade and to a variety of foreign business enterprises. The locational preferences of foreign banks in relation to their countries of origin are addressed in some detail.  相似文献

In the second paper of a symposium devoted to the contemporary status of Belarus, a noted American specialist on the electoral geography of the states of the former Soviet Union challenges assertions in the preceding article (Ioffe and Yarashevich, 2011) that only Russia and Ukraine are valid comparators against which to gauge the success of the Lukashenka model. Expanding the scope of comparison to include the three other countries neighboring Belarus (Latvia, Lithuania, and Poland), he demonstrates that a broader range of policy changes can be considered by its leadership in efforts to limit damage from the economic crisis in Belarus and position the country for renewed growth within a global economic frame-work. Examination of a wide range of social and economic indicators and government policies reveals, however, that in many ways an unreformed Belarus is poorly positioned for competition in an increasingly interconnected world, in which the elements for successful development are quite different from those providing economic stability in the past. A closing section of the paper revisits the debate on whether most Belarusian citizens actually aspire to a more "European" way of life or instead prefer the "Eastern" alignment and reliance on a Russian benefactor whose own economic future looks increasingly uncertain.  相似文献
