Abstract

Twenty-one volunteers tested the usability of revisions to the Texas A&M University Libraries' SFX® OpenURL link resolver menus, including the addition of Ex Libris' new bXâ?¢ recommendation service and a plug-in which pulls additional information about the journal into the menu. The volunteers also evaluated the quality and desirability of the bX recommendations and discussed their preferences for help options and full-text format. Results of the usability testing are reported along with the resultant menu changes. This study will be of interest to librarians implementing or redesigning OpenURL menus as well as those interested in the user experience.  相似文献

In parallel group trials, long‐term efficacy endpoints may be affected if some patients switch or cross over to the alternative treatment arm prior to the event. In oncology trials, switch to the experimental treatment can occur in the control arm following disease progression and potentially impact overall survival. It may be a clinically relevant question to estimate the efficacy that would have been observed if no patients had switched, for example, to estimate ‘real‐life’ clinical effectiveness for a health technology assessment. Several commonly used statistical methods are available that try to adjust time‐to‐event data to account for treatment switching, ranging from naive exclusion and censoring approaches to more complex inverse probability of censoring weighting and rank‐preserving structural failure time models. These are described, along with their key assumptions, strengths, and limitations. Best practice guidance is provided for both trial design and analysis when switching is anticipated. Available statistical software is summarized, and examples are provided of the application of these methods in health technology assessments of oncology trials. Key considerations include having a clearly articulated rationale and research question and a well‐designed trial with sufficient good quality data collection to enable robust statistical analysis. No analysis method is universally suitable in all situations, and each makes strong untestable assumptions. There is a need for further research into new or improved techniques. This information should aid statisticians and their colleagues to improve the design and analysis of clinical trials where treatment switch is anticipated.

This study considers the effectiveness of initial teacher education in one university college in Northern Ireland in preparing students for teaching in an increasingly diverse society and promoting a culture of tolerance. A cohort of 168 students in their final year were surveyed and this was followed by three focus group interviews. The findings showed that the student population came from a largely similar sociocultural background, with little prior experience of diverse contexts. Although students viewed the accommodation of diversity as an important issue for teachers, a limited number felt comfortable with and prepared for dealing with diversity in the classroom. The paper proposes that alternative strategies need to be employed to ensure the more effective preparation of beginning teachers.  相似文献

Young people and the division of labour in farming families   总被引:2,自引:0,他引:2  
The family farm has been identified as the main unit of agricultural production in Britain and it has been widely studied as an economic unit in agricultural research. However, it is also a social unit: one with a division of labour based upon gender and generation. Here we will consider a relatively unexplored area of agricultural production: the contribution of children to the family farm, based upon a quantitative survey of young people in a rural area and detailed qualitative interviews. The approach is to look at the farm family in terms of a ‘household work strategy’ although in the paper we argue that this should take into account the importance of moral obligation and patriarchal ideology. The importance of gender and generation are explored as intersecting factors in the division of labour.  相似文献

Difficult times in the supervision of psychotherapists are shown to have the potential for making positive contributions to the teaching/learning process. The concept of parallel process is central to this paper, along with emphasis on the supervisor's self-awareness and use of her inner experience, positive and negative countertransference, and Kohut's concept of the selfobject transferences. A number of case examples illustrate these ideas.An earlier version of this paper, entitled Parallel Processes and the Impact of Supervision on Treatment, was delivered at the Psychotherapy Institute Symposium in Berkeley, California, on November 4, 1984.  相似文献

The OECD questions whether non‐state services in fragile states may delegitimise the state in the eyes of citizens, arguing that ‘state‐building’ depends on governments’ engagement in service management. This article reviews the available evidence to identify what types of engagement are feasible and most likely to contribute to service delivery, or not to damage it. It considers the capacity requirements and the risks associated with state intervention through policy formulation, regulation, contracting and mutual agreements, and concludes by identifying ways of incrementally involving the state, beginning with activities that are least likely to do harm to non‐state provision.  相似文献

Stability and change in mother–adolescent conflict reactions (CRs) and the prediction of CRs from adolescents' earlier behavior problems (and vice versa) were examined with 131 mothers and their adolescents (63 boys). Dyads engaged in a 6‐min conflict discussion twice, 2 years apart [M age was 13 at Time 1 (T1)]. Non‐verbal expressive and verbal CRs during the conflict discussion were coded. Mothers, fathers, and teachers reported on adolescents' problem behaviors. There was inter‐individual (rank‐order) stability for adolescents' CRs whereas mothers' reactions were less stable. Mean levels of mothers' negativity, anger, and positive reactions and adolescents' negativity declined with time. Mothers’ CRs, more often than adolescents’ CRs, predicted and were predicted by adolescents’ problem behaviors in zero‐order correlations. In structural equation models with the stability of the constructs accounted for, adolescents' externalizing problems at T1 predicted higher maternal anger at Time 2 (T2). Mothers' anger and positive CRs at T1 predicted fewer T2 adolescents' internalizing problems. Stability and change in CRs are discussed.  相似文献

I discuss in this article the challenge of addressing people's psychosocial needs when the causes of problems are environmental or structural. I argue that poverty can be addressed only by tackling its structural causes and removing social inequalities. In so doing, I argue that a range of antipoverty measures introduced by the government have proved ineffective, including neoliberal measures to foster economic growth, such as GEAR and ASGISA, public works programmes, social security, and poverty alleviation projects (PAPS) which, while mildly effective, were poorly administered. My strategy of choice is an 'all hands to the pumps' approach involving participatory community development, social action, policy change and joint partnership between civil society, the state and the private sector. I do not suggest particular approaches or solutions but highlight the role of social workers and community development workers in poverty alleviation.  相似文献

Brenot  Jean  Bonnefous  Sylviane  Marris  Claire 《Risk analysis》1998,18(6):729-739
Cultural Theory, as developed by Mary Douglas, argues that differing risk perceptions can be explained by reference to four distinct cultural biases: hierarchy, egalitarianism, individualism, and fatalism. This paper presents empirical results from a quantitative survey based on a questionnaire devised by Karl Dake to measure these cultural biases. A large representative sample (N = 1022) was used to test this instrument in the French social context. Correlations between cultural biases and perceptions of 20 social and environmental risks were examined. These correlations were very weak, but were statistically significant: cultural biases explained 6%, at most, of the variance in risk perceptions. Standard sociodemographic variables were also weakly related to risk perceptions (especially gender, social class, and education), and cultural biases and sociodemographic variables were themselves inter correlated (especially with age, social class, and political outlook). The authors compare these results with surveys conducted in other countries using the same instrument and conclude that new methods, more qualitative and contextual, still need to be developed to investigate the cultural dimensions of risk perceptions. The paper also discusses relationships between perceptions of personal and residual risk, and between perceived risk and demand for additional safety measures. These three dimensions were generally closely related, but interesting differences were observed for some risk issues.  相似文献

Including ADHD?   总被引:1,自引:1,他引:0  
This article tries to make sense of the recent rise of Attention Deficit Hyperactivity Disorder in Britain by focussing on the contribution of the press, parents organisations, 'experts' and the drug companies, in the context of the current marketisation of education and health services. It draws on findings from a research project which studied press coverage of ADHD, and argues that the existence of active parents' organisations pushing for medical diagnoses and drug treatment for their children presents a challenge to our thinking about inclusion.  相似文献
