Readers’ trust on the medical literature has been eroded, and journal editors and some editorial boards are taking measures to ensure that authors fully and accurately report research findings and disclose conflicts of interest. This article describes a case study in which the papers editor of the World Health Organization (WHO) Bulletin influenced the content of an article that had been approved by the external reviewers. The editor objected to the publication of the large price differentials of the new molecular entities (NMEs) across the Latin American countries where they had been tested and the limited added therapeutic value of the NMEs that had been assessed by independent drug bulletins. This article summarizes the exchanges with WHO staff and posits the hypothesis that the WHO Bulletin might be affected by the shifts in WHO financing. Several authors have raised concern about the impact of financial conflicts of interest in WHO activities in the field of nutrition, intellectual property, and in the emergency response to the flu pandemic. Moreover, it has been reported that powerful WHO contributors pressured WHO into revising its publication policy. This is the first time that authors question if these conflicts of interest are also affecting the editorial independence of the WHO Bulletin.  相似文献

In this paper, the exhaustive search principle used in functional trees for classifying densities is shown to select variables with more split points. A new variable selection scheme is proposed to correct this bias. The Pearson chi-squared tests for associated two-way contingency tables are used to select the variables. Through simulation, we show that the new method can control bias and is more powerful in selecting split variable.  相似文献

Sousa et al. (2010 Sousa , R. , Shabbir , J. , Real , P. C. , Gupta , S. ( 2010 ). Ratio estimation of the mean of a sensitive variable in the presence of auxiliary information . J. Statist. Theor. Prac. 4 ( 3 ): 495507 .[Taylor & Francis Online] [Google Scholar]) introduced a ratio estimator for the mean of a sensitive variable and showed that this estimator performs better than the ordinary mean estimator based on a randomized response technique (RRT). In this article, we introduce a regression estimator that performs better than the ratio estimator even for modest correlation between the primary and the auxiliary variables. The underlying assumption is that the primary variable is sensitive in nature but a non sensitive auxiliary variable exists that is positively correlated with the primary variable. Expressions for the Bias and MSE (Mean Square Error) are derived based on the first order of approximation. It is shown that the proposed regression estimator performs better than the ratio estimator and the ordinary RRT mean estimator (that does not utilize the auxiliary information). We also consider a generalized regression-cum-ratio estimator that has even smaller MSE. An extensive simulation study is presented to evaluate the performances of the proposed estimators in relation to other estimators in the study. The procedure is also applied to some financial data: purchase orders (a sensitive variable) and gross turnover (a non sensitive variable) in 2009 for a population of 5,336 companies in Portugal from a survey on Information and Communication Technologies (ICT) usage.  相似文献

Educational programs in human service professions such as social work, criminal justice, psychology, and public administration stress the importance of recognizing domestic/intimate partner violence as well as elder abuse. Students' abilities to recognize domestic violence in older couples have not been well-investigated. In this study, three vignettes were developed (Pat and Lee at age 75, Pat and Lee at age 30, Imagine yourself with Lee at age 75) in which intimate partner violence was perpetrated by the character Lee. Twenty-five items followed each vignette. When the variables of educational standing (graduate/undergraduate), ethnicity, and academic major were controlled, there were significant differences between the vignettes in 14 of 25 items (General Linear Model, F = 1.552, df = 50, p = .012). More than three out of four respondents for each vignette identified this as domestic violence and believed there was potential for serious harm. However, respondents were less likely to believe that a 75-year-old partner would know when to terminate a relationship in which there was intimate partner violence. Respondents who were asked to imagine themselves with Lee at 75 were likely to perceive Lee as more dangerous than respondents for the other vignettes. Implications are considered for educators.  相似文献

There is an increasing incidence of new HIV‐1 diagnoses among black Caribbeans in the UK, but there has been limited research in this area. The LIVITY study is the first in‐depth epidemiological and behavioural study to examine the impact of HIV among black Caribbeans in the UK. The UK black Caribbean community has traditionally been regarded as less likely to participate in clinical research and surveys. We identified three major challenges to recruitment to the LIVITY study: general distrust of the research process; the considerable stigma surrounding HIV in the black Caribbean community and the sensitivity of obtaining detailed sexual histories. The strategies devised to help overcome these barriers to optimise recruitment included: the establishment of a black Caribbean Community Advisory Group to facilitate communication between the community and the researchers and assist in questionnaire design to improve acceptability to the participants; use of healthcare practitioners as gatekeepers; extensive piloting and modification of the questionnaire among black Caribbean patients; reassurances of confidentiality during recruitment; and ethnic matching between interviewer and study participants. Another challenge was the high rate of loss to follow‐up among eligible patients, potentially compromising the study’s generalisability. Nevertheless, use of the above strategies resulted in a satisfactory enrolment rate of 57%, who were representative of all eligible patients.  相似文献

This paper reports the findings of a study of explicit and implicit learning and gambling with non-problem (n = 107), sub-clinical problem gamblers (n = 13), and probable pathological gamblers (n = 46). Two probability learning tasks modeled after gambling games and an artificial grammar task were used to explore how people learn patterns. In each of the two probability learning tasks, the outcome of the game was biased during the first part (learning phase) of the task. The results showed that many of the participants in the experimental conditions learned the bias and gradually unlearned the bias during the extinction phase of the study. Probable pathological gamblers showed less retention of the bias during two probability tasks and repeated the same errors during the artificial grammar task suggesting that they emphasize explicit learning strategies rather than implicit learning strategies. The results are consistent with the idea that pathological gamblers are more likely to utilize explicit rules than implicit rules.  相似文献

Abstract

In spite of growing interest in spirituality and religion, and the prominent position given to religion in social work's educational policies and ethical standards, no studies have explored the profession's level of spiritual sensitivity. Accordingly, we examined the visibility of faith groups and their characterizations in 71 influential social work textbooks. This study found that faith groups, in contrast to a number of comparison groups, were essentially invisible as populations worthy of students' direct attention. Further, when faith groups were discussed, they tended to be characterized in a biased, spiritually insensitive manner. To move toward spiritual competency, social work must increase the amount of material devoted to faith groups and ensure that they are depicted in a manner that is consistent with their worldviews.  相似文献

Being responsible mainly to their superiors, decision-makers at the county level in China pursue the maximum growth rate rather than their residents’ welfare. This leads to a preference for productive expenditure in their fiscal decisions. An empirical test based on 2,067 counties (cities) provides robust evidence for the existence of productive expenditure bias at the county level. Such bias causes a serious impediment to the construction of a system of public finance and the transformation to public service-oriented government in China. An appropriate solution to this problem is to gradually enhance incentives for county- level governments to satisfy the demands of local residents.  相似文献

We analyze mechanisms of moral disengagement used to eliminate moral consequences by industries whose products or production practices are harmful to human health. Moral disengagement removes the restraint of self-censure from harmful practices. Moral self-sanctions can be selectively disengaged from harmful activities by investing them with socially worthy purposes, sanitizing and exonerating them, displacing and diffusing responsibility, minimizing or disputing harmful consequences, making advantageous comparisons, and disparaging and blaming critics and victims. Internal industry documents and public statements related to the research activities of these industries were coded for modes of moral disengagement by the tobacco, lead, vinyl chloride (VC), and silicosis-producing industries. All but one of the modes of moral disengagement were used by each of these industries. We present possible safeguards designed to protect the integrity of research.  相似文献
