The parameter O in the problem of the Nile is tested using the Sequential Probability Ratio Test (SPRT). It is observed that the test can be used to discriminate between two one–sided hypotheses.  相似文献

SCOAP3 is an innovative Open Access initiative for publishing in high-energy physics. The model is viewed by many as a potential solution to multiple issues related to the financial crisis, the peer review system, scholarly communication, and the need to support institutional repositories. This installment of “The Balance Point” presents articles written by three Open Access advocates, outlining the SCOAP3 proposal, benefits of participation, and some of the roles libraries, publishers and scientists can play in making important changes to scholarly communication. Contributors discuss scalability and transferability issues of SCOAP3, as well as other matters of concern.  相似文献

In this paper, we consider how the cultural politics of austerity within Britain plays out on the celebrity maternal body. We locate austerity as a discursive and disciplinary field and contribute to emerging feminist scholarship exploring how broader political and socio-economic shifts interact with cultural constructions of femininity and motherhood. To analyse the symbolic function of mediated celebrity maternity within austerity, the paper draws on a textual analysis of three celebrity mothers: Kate Middleton, Kim Kardashian, and Beyoncé. This analysis was undertaken as part of a larger qualitative study into celebrity culture and young people's classed and gendered aspirations. We show how these celebrity mothers represent the folk devils and fantasy figures of the maternal under austerity—the thrifty, happy housewife, the benefits mum, and the do-it-all working mum—and attempt to unpick what cultural work they do in the context of austerity within Britain. Through the lens of celebrity motherhood, we offer a feminist critique of austerity as a programme that both consolidates unequal class relations and makes punishing demands on women in general, and mothers in particular.  相似文献

Abstract

Objective: To conduct a confirmatory factor analysis on the 17-item Sexual Health Survey (SHS), a comprehensive instrument designed to be used with college students. Participants: College students (N = 515) aged 18 to 26 years enrolled at a Midwest public university October 2009. Methods: Confirmatory factor analysis with maximum likelihood estimation was performed to test the stability of the constructs. Results: All factor loadings were significant (p < .001), ranging from .55 to .99 (standardized). The range of squared multiple correlations of items was .31 to .98, and the intercorrelations among the 5 factors were from ?.03 to .52. These small to moderate levels of intercorrelation support discriminant validity of 5 constructs. Conclusions: This study supports the 5-factor version of the 17-item SHS as a viable scale that can measure sexual health overall and 5 distinct areas. College health professionals should consider use of this scale for assessment purposes and evaluation of programmatic efforts.  相似文献

This paper examines the battle to reform and streamline the planning system in Sydney, Australia, between 2005 and 2013. It analyses the strategies the State of NSW has pursued to manage ongoing conflicts over development, and reflects on the challenges the State has encountered in its attempt to redefine democratic engagement, justify decisions, claim legitimacy and forge a consensus around a more pro-development planning system. While New South Wales’ planning reform strategies have pursued an apparently ‘post-political’ agenda (Swyngedouw, Apocalypse forever? Post-political populism and the spectre of climate change, Theory Culture and Society, 27(2–3):213–232, 2010), using policy solutions to depoliticize difficult decisions, the reform process has exacerbated rather than defused conflicts. The story raises questions about the extent to which the new governing strategies of a post-political era can offer effective forums to forge consensus, or to stage-manage agreement over metropolitan development conflicts.  相似文献

Group Material’s Timeline: The Chronicle of US Invention in Latin and Central America (1984) at P.S.1’s Center for Contemporary Art explored the framing devices of installation art and photography in tandem, as a means of reconfiguring the distribution of the sensible at the height of the Cold War. In response to escalating crisis (including continuous Central Intelligence Agency operations being carried out in Nicaragua and El Salvador), this activist project employed postmodern strategies such as appropriation, pastiche and a resistance to conclusiveness in order to suggest provocative and unexpected dialogues between disparate artworks and artefacts across time and geopolitical difference. Artists ranging from Richard Prince and Barbara Kruger to John Heartfield, Tina Modotti and Arellano Bolivar, among others, come together as signs of political and aesthetic conflict, as networks of visual culture that complicate dominant narratives of spatial and temporal reality during the Cold War era. Closer analysis of such works reveals historical ruptures alongside continuities, relayed by official government policy, mass media and the art world more broadly. By excavating a long-standing history of conflict, Timeline addresses the stakes of the ownership of meaning itself in the mid-1980s, with implications regarding art production and politics for generations to come.  相似文献

A doctoral student approached the column editor and suggested that an update on a “The Balance Point” column entitled “The One-Box Challenge: Providing a Federated Search That Benefits the Research Process” (2006) would be of interest and useful to readers, and the editor agreed. Contributors to the original column were asked to reflect upon their experiences with federated searching, including successes and failures over the past 10 years, and to provide insights into future challenges and issues. This edition of “The Balance Point” focuses on the ongoing challenges, lessons learned, possible future directions, and issues involved in providing one-box searching to library patrons.  相似文献
