While qualitative researchers increasingly accept online video interviews as a reliable method, many maintain concerns about rapport and data quality. Drawing on two separate interview projects conducted in private in-person settings, public in-person settings, and privately via Skype, we compare interview contexts with regard to rapport, suitability to sensitive topics, interview duration, and scheduling concerns raised by prior research. Analytical comparison of these two corpuses of data suggest, largely in contrast to previous literature, that (1) interviews conducted in private settings (either in-person or via Skype) result in more sharing of deeply personal experiences, and there is little difference in this exceptional disclosure between Skype and in-person private interviews; (2) interviewing via Skype produces neither reduction nor inappropriate excesses of rapport; and (3) Skype interviews are a popular choice among participants, did not result in shorter interview duration, and were not subject to greater rescheduling or cancellation.  相似文献

In drug development, it sometimes occurs that a new drug does not demonstrate effectiveness for the full study population but appears to be beneficial in a relevant subgroup. In case the subgroup of interest was not part of a confirmatory testing strategy, the inflation of the overall type I error is substantial and therefore such a subgroup analysis finding can only be seen as exploratory at best. To support such exploratory findings, an appropriate replication of the subgroup finding should be undertaken in a new trial. We should, however, be reasonably confident in the observed treatment effect size to be able to use this estimate in a replication trial in the subpopulation of interest. We were therefore interested in evaluating the bias of the estimate of the subgroup treatment effect, after selection based on significance for the subgroup in an overall “failed” trial. Different scenarios, involving continuous as well as dichotomous outcomes, were investigated via simulation studies. It is shown that the bias associated with subgroup findings in overall nonsignificant clinical trials is on average large and varies substantially across plausible scenarios. This renders the subgroup treatment estimate from the original trial of limited value to design the replication trial. An empirical Bayesian shrinkage method is suggested to minimize this overestimation. The proposed estimator appears to offer either a good or a conservative correction to the observed subgroup treatment effect hence provides a more reliable subgroup treatment effect estimate for adequate planning of future studies.  相似文献

Social crises are a huge challenge to the performance of the media. The norms and routines of news making with which journalists comply can become problematic in the context of intensive public sentiment and empathy. News values, including the sacred belief in objective reporting, are questioned in the light of controversies over editorial judgment within and outside the newsroom. I examine the contested news values that manifested in the Umbrella Movement of Hong Kong in 2014. In particular, I focus on the arguments and deliberations regarding news objectivity, which involved several parameters of the performance of the media during this social crisis.  相似文献

The CPMP Points to Consider on Adjustment for Baseline Covariates recently came into operation. As well as providing sound guidance, this document states a strong position against dynamic allocation. This paper reviews the most important issues involved and aims to stimulate interest in further investigating alternative allocation methods in clinical trials.

This paper examines available international data relevant to the World Health Organization model of health status. It explores the possibility of constructing useful measures of health status, health policy, social and economic status, and provision of health care based on these data. A five-factor model is developed and tested empirically using World Bank statistical data from 123 countries. Two factors representing dimensions of country affluence and population density are found to explain 78 percent of the variations in the health status indicator. The countries with health status indicator levels worse than those predicted by the model are predominantly third-world countries; a majority are African. Countries with health status indicator levels better than predicted are mainly in Asia, Latin America, and Europe. Some generally accepted causal relationships were not supported by the findings in this analysis.  相似文献

Adolescents' effortful control is subject to numerous maternal influences. Specifically, a mother's own effortful control is associated with her child's effortful control. However, maternal substance use, psychopathology, and stress within the parenting role may also lead to poor effortful control for their child. Poor effortful control during adolescence can subsequently contribute to a variety of negative outcomes, including externalizing behaviors. A sample of 460 adolescents (47% female, 59.3% Non‐Hispanic Caucasian) was selected from a longitudinal, multigenerational study. The goal was to examine maternal effortful control, substance use, psychopathology, and stress in their offspring's childhood (Mage = 6.27) and their influence on their children's effortful control in early adolescence (Mage = 12.21) and the subsequent effect of effortful control on adolescents’ externalizing behavior (Mage = 13.53). Maternal effortful control (measured via conscientiousness) and psychopathology were associated with adolescent effortful control, which was associated with externalizing behavior a year later. Additionally, there was a significant indirect association between maternal effortful control and adolescent externalizing behaviors via adolescent effortful control. Thus, adolescent effortful control is associated with maternal effortful control but also subject to specific maternal risk factors in childhood. These results inform potential maternal strategies for promoting positive developmental outcomes in adolescents.  相似文献

Measuring organizational performance plays a very important part in translating corporate strategy into results. Various emerging (non-traditional) performance systems have recently been devised to aid firms in selecting and implementing measures. This paper discusses the strategy/measurement initiatives and compares ten emerging performance measurement systems with respect to a list of performance dimensions, the characteristics of performance measures, and the requirements of development process. Although these systems have constraints borne with their own application domains, they stand by themselves empirically and/or theoretically, and provide guidance about what to measure and how to design performance measures that could be linked to the corporate strategy and objectives of an organization. This paper concludes that there is a need to develop a paradigm for integrating strategy formulation and performance measurement in organizations.  相似文献
