Two-treatment multi-center clinical trials are the most common type of clinical trials in practice. The aim of this paper is to discuss a curious property of certain standard nonparametric procedures used in the analysis of such clinical trials. Different analyses of a simulated data example are presented, which lead to contrasting and surprising results. The source of the potentially misleading outcome is then explored while relating the simulated data with the concept of Efron's paradox dice and the notion of nontransitivity. With the root of the problem established, an alternate nonparametric method from the literature is shown to address the problem. Finally, pointing out an interpretational concern of using the alternate procedure, a modification to this procedure is also suggested and corresponding theoretical results are presented. 相似文献

Interpretations and perceptions of the effects and content of rap music lyrics have been given considerable attention in the literature in recent years, yet few assessment tools have been developed that can produce reliable and valid inferences about these views. One exception is the Rap-music Attitude and Perception (RAP) Scale. This study examined the cross-racial effects on attitudes toward and perceptions of rap music using a sample of 1,254 college students. A cross-sectional survey design was used to gather these data. Three specific hypotheses were tested and were supported or partially supported. Alpha reliabilities for the full scale and for each of the three sub-scales were good for black and white students separately. Criterion validity for these groups was also good. Finally, tests of factorial equivalence suggested that the factor structure of the RAP was equivalent across racial groups. The RAP is a tool with strong psychometric properties and can be used by practitioners and researchers working with black and white subgroups. Directions for future research on the utility of the RAP are forwarded. 相似文献

This paper examines global English-language newspaper coverage of the death of David Bowie. Drawing upon the concept of reification, it is argued that the notion of celebrity is discursively (re)produced and configured through a ‘public face’ that is defined, maintained and shaped via media reports and public responses that aim to know and reflect upon celebrity. The findings highlight how Bowie’s reification was supported by discourses that represented him as an observable, reified form. Here, Bowie’s ‘reality’, that is, his authentic/veridical self, was obscured behind a façade of mediation, interpretation and representation that debated and decided his ‘authenticity’ as a cultural icon. Such debates, however, were engagements with a reified image, enveloped in continual (re)interpretation. As a result, Bowie’s reification was grounded in a polysemous process that allowed numerous versions of ‘himself’ to be aesthetically reimagined, reinvented and repeated. 相似文献

This article provides the most recent U.S. prevalence estimates of forced sex and unwanted sexual activity. Results of a national telephone survey conducted in 2001-2003 indicate that 1 in 59 U.S. adults (2.7 million women and 978,000 men) experienced unwanted sexual activity in the 12 months preceding the survey and that 1 in 15 U.S. adults (11.7 million women and 2.1 million men) have been forced to have sex during their lifetime. There were 60.4% of females and 69.2% of males who were 17 years old or younger at the time the first forced sex occurred. This study provides an update to the National Violence Against Women Survey with more recent national data. Findings suggest that victimization rates have remained consistent since the 1990s. These findings suggest that a continued effort toward primary prevention of sexual violence, particularly rape of children and adolescents, is needed. 相似文献

Effective collaborative working between the different professions and agencies working to safeguard children is essential. Lack of knowledge of others' roles, perceived differences in status and expertise, and negative stereotypes are examples of why this can be difficult to achieve. A facilitated interprofessional learning (IPL) programme was implemented to assess if such an intervention could overcome some of the barriers to effective interprofessional and inter‐agency team working. Six teams based in primary and secondary care trusts took part with participants from health, education, police and social services. Quantitative and qualitative data were collected from individual participants using a pre‐validated team climate inventory and reflective statements. Findings from this study demonstrate statistically significant changes in five out of six categories in the inventory. Reflective statements suggested that overall the programme offered a positive learning experience at both an individual and team level. The importance of outside facilitation to maintain the team's momentum was acknowledged, as was the difficulty of maintaining a good level of activity once the programme had ended. Nevertheless, the IPL programme provided a timely opportunity to reflect upon the interprofessional and inter‐agency team working needed within Children's Trusts and the implications for staff involved with regard to skills development.

During the modern phase of economic reforms directed at the establishment of market economy, many countries with transition
economies face the challenge of solving the issue of formation and rational usage of internal sources of financing the real
sector of the economy, as well as attracting considerable volume of direct foreign investment. In general, financial market
imperfections hold back innovation and growth, and that public policy can complement financial markets. Therefore, the most
relevant issue at the present time is the formation of attendant and complex supervision institutions, as well as an exigency
of innovative economy governance as mainframe principles for further banking system elaboration and financial sector development
in general. We have taken Armenia as a case study for transition economy as far as Armenia is currently in the stage of capital
market development through integration into international financial markets.
