In constructing exact tests from discrete data, one must deal with the possible dependence of the P‐value on nuisance parameter(s) ψ as well as the discreteness of the sample space. A classical but heavy‐handed approach is to maximize over ψ. We prove what has previously been understood informally, namely that maximization produces the unique and smallest possible P‐value subject to the ordering induced by the underlying test statistic and test validity. On the other hand, allowing for the worst case will be more attractive when the P‐value is less dependent on ψ. We investigate the extent to which estimating ψ under the null reduces this dependence. An approach somewhere between full maximization and estimation is partial maximization, with appropriate penalty, as introduced by Berger & Boos (1994, P values maximized over a confidence set for the nuisance parameter. J. Amer. Statist. Assoc. 89 , 1012–1016). It is argued that estimation followed by maximization is an attractive, but computationally more demanding, alternative to partial maximization. We illustrate the ideas on a range of low‐dimensional but important examples for which the alternative methods can be investigated completely numerically. 相似文献

Research in alternative media has burgeoned since the turn of the millennium. The majority of studies has examined the political and social dimensions of alternative media and has focused on the media of social movements. The value of these amateur media projects lies not only in the content they produce, but also in the educational and political empowerment they offer to their participants. Other forms of alternative media, such as blogs and fanzines, present challenges to mainstream journalism; they challenge the exclusive authority and expertise of professional journalists. Recent research has begun to examine the relationship between alternative and mainstream media practices, particularly examining how alternative media offer ways of rebalancing media power and how 'ordinary' people are able to represent their own lives and experiences and concerns in ways that are often ignored or marginalised by the dominant media institutions. However, we need to learn more about specific alternative media practices and how audiences use their content. 相似文献

This article uses the theory of uneven and combined development (U&CD) to produce a novel explanation of ‘Brexit and Trump’ – the two shock political events of 2016. The argument proceeds in three steps. First, we identify the global conjuncture of historical unevenness in which the votes occurred: how the neoliberal transformation of the advanced capitalist countries was synchronized with the radically different process of primitive accumulation in China. Second, we apply the theory of U&CD to this peculiar ‘simultaneity of the non‐simultaneous’: the ‘big country’ effects of China's industrialization, we find, were thrice multiplied by its combination with the advanced sectors of the world economy, which accelerated China's take‐off, brought forward its export phase, and widened its export profile at a moment of maximum openness in international trade. Finally, this produced the pattern of development that led to the events of 2016: the resultant trade shocks intensified the internal inequalities of British and American societies in ways that match the geography of the Leave and Trump votes. The analysis has a wider intellectual implication too, for the phenomena of historical unevenness and combination are intrinsic to the history of the global political economy; and the theory of U&CD therefore has a unique contribution to make to the field of International Political Economy. 相似文献

In this paper we argue that Emile Durkheim's sociology contains within it a theory of society and religion as a form of embodied intoxication that is implicit in his writings on effervescent assemblies but has not yet been explicated or developed fully by subsequent commentators. This holds that for social or religious collectivities to exist, the bodies of individuals must be both marked by insignia, customs and techniques that facilitate the possibility of culturally normative patterns of recognition, interaction and action, while also being excited, enthused or intoxicated sufficiently to be inhabited as collective rather than egoistic beings. Our paper begins by investigating the central features of Durkheim's theory – including his interest in the ritual steering of these processes – as developed most fully in his last major study, The Elementary Forms of Religious Life. We then develop our own analysis of Durkheim's concern that modernity has stimulated a rise in ‘abnormal’ forms of embodied intoxication that fail to attach individuals to the wider societies in which they live, and demonstrate the utility of our analytical framework by employing it to assess the recent resurgence of charismatic Christian revivalism. 相似文献

This paper theorises historical prison escapes by male prisoners from Scottish prisons, arguing that they represent a form of hegemonic masculinity. That dominant masculinity parallels recapture narratives constructed by the official masculinity associated with military service and its transfer to the prison ethos. Manly soldiering cultivated in prison officers with previous military service suited them to security duties. Violence, cunning, determination and athleticism is reflected in the escape bids, and human needs. These escapes occurred before electronic technology secured prison estates, so the strength and vigilance of the prison officers was essential. The sociology of escapes and the prison community literature underpins the paper's narrative analysis. It is concluded that escape data offers opportunities to understand the material nature of escape processes, and the representation of masculinity as reflected through accounts of technologies implemented in escapes, as well as to how the state represents prison escapes. By connecting masculinity to prison escape processes, a conceptual bridge is created between prison culture and concepts of masculinity. The latter, it is argued, are represented in narrative depictions of escapes. Escape narratives teach us about material forms of legal violence and embrace a tacit recognition of heterosexual manliness. 相似文献

We develop a Bayesian approach for parsimoniously estimating the correlation structure of the errors in a multivariate stochastic volatility model. Since the number of parameters in the joint correlation matrix of the return and volatility errors is potentially very large, we impose a prior that allows the off-diagonal elements of the inverse of the correlation matrix to be identically zero. The model is estimated using a Markov chain simulation method that samples from the posterior distribution of the volatilities and parameters. We illustrate the approach using both simulated and real examples. In the real examples, the method is applied to equities at three levels of aggregation: returns for firms within the same industry, returns for different industries, and returns aggregated at the index level. We find pronounced correlation effects only at the highest level of aggregation. 相似文献

Regulation as Country‐Specific (Dis‐)Advantage: Smoking Bans and the Location of Foreign Direct Investment in the Tobacco Industry 下载免费PDF全文
This paper seeks to examine the relationship between smoking bans and the propensity of tobacco firms to engage in foreign direct investment (FDI). Using international business theory based on the firm‐specific advantage/country‐specific advantage (FSA/CSA) matrix, the authors show that, contrary to what one may expect, smoking bans at home are an important institutional intervention, reducing the propensity for firms to engage in FDI, even to countries without a ban themselves. 相似文献

Among the challenges faced by Latin America at the onset of the 21st century is the increase in crime and violence that began in the mid-1980s, and which, to one degree or another, has afflicted most countries in the region. In this study we explore the potential implications of the upsurge in crime on migration by testing the hypothesis that crime victimization in Latin America increases the probability that people have given serious thought to the prospect of migrating with their families to the United States. Using Latinobarometro public opinion surveys of approximately 49,000 respondents residing in 17 countries in 2002, 2003, and 2004, the results of a Hierarchical Generalized Linear Model found that, net of individual and country-level control variables, the probability of seriously considering family migration to the United States was around 30 percent higher among respondents who reported that they or a member of their family was a victim of a crime sometime during the year prior to the survey. Evidence that victimization promotes the propensity to emigrate is a finding that contributes to an understanding of the transnational consequences of the increase in crime in Latin America, and adds a new variable to the inventory of factors that encourage people to migrate to the United States. 相似文献

Abstract The movement of some women into self employment is considered in this paper. It is argued that if this movement is to be successful, and thus have any influence on the equality of employment opportunities, then it is necessary for the business ventures involved to be run strategically rather than operationally. It is also argued that there must be greater scope and encouragement for innovation in this area, otherwise there is a danger of mirroring, in new business formation, the structure of inequality that applies to the formal, and declining, structure of current employment. Finally, the paper examines the need for women's entrepreneurial ventures to be better accepted by and integrated into the wider social fabric. The potential sources of stress and of satisfaction in women's self employment are noted. 相似文献
