Rational Irrationality and the Microfoundations of Political Failure

Models of inefficient political failure have been criticized forimplicitly assuming the irrationality of voters (Wittman, 1989,1995, 1999; Coate and Morris, 1995). Building on Caplan's (1999a,1999b) model of ``rational irrationality'', the current papermaintains that the assumption of voter irrationality is boththeoretically and empirically plausible. It then examinesmicrofoundational criticisms of four classes of political failuremodels: rent-seeking, pork-barrel politics, bureaucracy, andeconomic reform. In each of the four cases, incorporating simpleforms of privately costless irrationality makes it possibleto clearly derive the models' standard conclusions. Moreover, itfollows that efforts to mitigate political failures will besocially suboptimal, as most of the literature implicitlyassumes. It is a mistake to discount the empirical evidence forthese models on theoretical grounds.

<正>Sino-American educational relations need more impetus Despite mounting tensions in geopolitics and the global economic arena,Chinese President Xi Jinping’s recent meeting with U.S.President Donald Trump was not just a boon for the leaders of the world’s largest economies,it also signaled a tailwind for students who are investing time in forming links between the two countries.     

Discourses of empire: the US ‘empire’, globalisation and international relations

The contemporary normalisation of discussing United States foreign policy in terms of imperialism and empire is of great interest to all scholars of international relations, and the purpose of the present article is to analyse this trend in terms of the broader context of the role of empire in international relations theorising. There is a deeper logic to the recognition of a truly imperial republic than just contemporary foreign policy, as the US as empire seems to convey a richer understanding and a deeper resonance of America's contemporary role. What is also striking are the ties between empire and globalisation, which are increasingly being recognised. The use of imperial language as a more general discourse questions the dominant assumptions in international relations concerning the state of anarchy in the international system, without abandoning the dynamics of power and coercion that are part and parcel of imperial relationships, which can help to convey a richer sense of the dynamics of the international realm.     

Silent citizens: reflections on community,habit, and the silent majority in political life

This article identifies two different senses in which the concept of ‘community’ can be seen to underpin the norm of vocal participation in democratic politics. The first is a broadly liberal view of community – traceable to Alexis de Tocqueville – that promotes active, vocal, and autonomous citizens and acts as a buffer between the state and the individual. A second broadly conservative view of community in the writings, for example, of Edmund Burke and T.S. Eliot treats community as organic, passive, and largely silent. It valorizes habit and habitual relationships as supporting political life through obedience to the law and respect for authority. While these two traditions stand apart, what is striking about both views of community is the one point about which both agree: citizens' sense of community is in decline within liberal democracies today. Thus silence and silent majorities are problematic to both traditions, albeit for different reasons.     

Pubertal Development Moderates the Importance of Environmental Influences on Depressive Symptoms in Adolescent Girls and Boys

Prevalence differences in depressive symptoms between the sexes typically emerge in adolescence, with symptoms more prevalent among girls. Some evidence suggests that variation in onset and progression of puberty might contribute to these differences. This study used a genetically informative, longitudinal (assessed at ages 12, 14, and 17) sample of Finnish adolescent twins (N = 1214, 51.6% female) to test whether etiological influences on depressive symptoms differ as a function of pubertal status. These tests were conducted separately by sex, and explored longitudinal relationships. Results indicated that pubertal development moderates environmental influences on depressive symptoms. These factors are more important on age 14 depressive symptoms among more developed girls relative to their less developed peers, but decrease in influence on age 17 depressive symptoms. The same effects are observed in boys, but are delayed, paralleling the delay in pubertal development in boys compared to girls. Thus, the importance of environmental influences on depressive symptoms during adolescence changes as a function of pubertal development, and the timing of this effect differs across the sexes.     

Recovery of DNA and fingerprints from touched documents

This study investigated the various factors affecting DNA profiling from DNA recovered from fingerprints deposited on paper before and after fingerprint enhancement treatments. The DNeasy^® plant mini kit (QIAGEN^®) was found to improve DNA recovery from paper by over 150% compared with the QIAamp^® mini kit. A significant decrease in the amount of DNA recovered was observed following treatment with DFO and/or Ninhydrin. This decrease in yield did not have a comparably significant effect on the quality of the SGM Plus™ profiles. Furthermore, this study found that whilst certain paper types, such as newspaper, magazine and filter paper allowed for the good recovery of DNA, common office paper and white card, strongly interfered with the recovery of DNA resulting in poor quality profiles.
