This paper reports the results of developing and evaluating a classification of 315 arrested youth processed at the Hillsborough County Juvenile Assessment Center from September 1, 1994 to January 31, 1998. Youth were characterized as physically or sexually abused if they reported abuse or if they had been referred to juvenile court for abuse. Stepwise logistic regression analysis revealed that family problems, friends' substance use, and delinquency involvement (marginally significantly related) were associated with both physical abuse and sexual victimization. In addition, physical abuse was associated with psychological problems and sexual victimization with being female, being older, and own substance use. The research implications of these results are discussed.  相似文献

While the benefits the volunteers offer nonprofit organizations are substantial, they can also cause problems for these groups. In an environment where people willingly donate their time and energy to a cause that they ostensibly support, why is disruptive behavior so common? This ethnographic study of volunteers at an animal shelter identifies the factors that lead to problematic behavior. The paper argues that disruptions occur when there is a mismatch between the needs of the volunteer and the needs of the organization and because of structural conditions that lead to uncertainty among volunteers. These findings shed light on volunteer behavior broadly and present the opportunity to address disruptive behavior. As a result, the benefits the volunteers provide for an organization can be maximized.  相似文献

ABSTRACT

This article reports on an effort to better understand the discoverability of ebook collections at the University of North Carolina at Chapel Hill (UNC-CH). Library staff analyzed titles in nine ebook packages across disciplines and conducted a two-pronged analysis of how discoverable titles in these collections were, both in Summon Discovery Service and the online catalog, and the quality of what could be discovered about the ebooks with these tools. This study revealed that discoverability of ebooks is not equal across collections, and some collections require more work to make them discoverable in Summon and the catalog. Finally, the majority of titles were discovered in Summon, but the catalog still seems to be a better discovery engine for these ebooks.  相似文献

Motives for gambling have been shown to be associated with gambling involvement, and hence important in the understanding of the etiology of problem gambling. The aim of this study was to describe differences in gambling motives in different subgroups of lifetime risk gamblers, categorized by: age, gender, alcohol- and drug habits and type of game preferred, when considering the level of risk gambling. A random Swedish sample (n = 19,530) was screened for risk gambling, using the Lie/Bet questionnaire. The study sample (n = 257) consisted of the respondents screening positive on Lie/Bet and completing a postal questionnaire about gambling and motives for gambling (measured with the NODS-PERC and the RGQ respectively). When considering the level of risk gambling, motives for gambling were not associated with gender, whereas younger persons gambled for the challenge more often than did older participants. Card/Casino and Sport gamblers played to a greater extent for social and challenge reasons then did Lotto/Bingo-gamblers. EGM-gamblers played more for coping reasons than did Lotto/Bingo gamblers. However, this association turned non-significant when considering the level of risk gambling. Moderate risk gamblers played for the challenge and coping reasons to a greater extent than low risk gamblers motives for gambling differ across subgroups of preferred game and between gamblers with low and moderate risk. The level of risk gambling is intertwined with motives for gambling and should be considered when examining gambling reasons.  相似文献

The analysis of adverse events (AEs) is a key component in the assessment of a drug's safety profile. Inappropriate analysis methods may result in misleading conclusions about a therapy's safety and consequently its benefit‐risk ratio. The statistical analysis of AEs is complicated by the fact that the follow‐up times can vary between the patients included in a clinical trial. This paper takes as its focus the analysis of AE data in the presence of varying follow‐up times within the benefit assessment of therapeutic interventions. Instead of approaching this issue directly and solely from an analysis point of view, we first discuss what should be estimated in the context of safety data, leading to the concept of estimands. Although the current discussion on estimands is mainly related to efficacy evaluation, the concept is applicable to safety endpoints as well. Within the framework of estimands, we present statistical methods for analysing AEs with the focus being on the time to the occurrence of the first AE of a specific type. We give recommendations which estimators should be used for the estimands described. Furthermore, we state practical implications of the analysis of AEs in clinical trials and give an overview of examples across different indications. We also provide a review of current practices of health technology assessment (HTA) agencies with respect to the evaluation of safety data. Finally, we describe problems with meta‐analyses of AE data and sketch possible solutions.  相似文献

This article addresses the portfolio management practices and challenges of contemporary firms. Based on a review of the extant literature on project selection, termination and deletion decisions, we conducted an in-depth interview study with 19 key informants in 11 multinational firms. We identified three genres of portfolio management decision making: formalist-reactive, intuitive, and integrative. Each genre can be described by a unique set of portfolio management practices. For example, formalist-reactive firms rely on quantitative criteria while intuitive firms prefer qualitative criteria. In addition, each genre has to overcome a unique set of challenges. We discuss the three genres in detail and provide several implications for portfolio management decision making.  相似文献

BackgroundThe Visual Analogue Scale (VAS) is one of the most widely used pain assessment scales in clinical practice and research. However, the VAS is used less frequently in midwifery than in other clinical contexts. The issue of how people interpret the meaning of the VAS endpoints (i.e. no pain and worst imaginable pain) has been discussed. The aim of this study was to explore midwifery students’ conceptions of ‘worst imaginable pain’.MethodsA sample of 230 midwifery students at seven universities in Sweden responded to an open-ended question: ‘What is the worst imaginable pain for you?’ This open-ended question is a part of a larger study. Their responses underwent manifest content analysis.ResultsAnalysis of the midwifery students’ responses to the open-ended question revealed five categories with 24 sub-categories. The categories were Overwhelming pain, Condition-related pain, Accidents, Inflicted pain and Psychological suffering.ConclusionsThe midwifery students’ conceptions of ‘worst imaginable pain’ are complex, elusive and diverse.  相似文献

Using a sample of 17 foundations that are at the forefront of encouraging innovation this study explored foundations' motivations behind funding innovation, their perceived ability to impact the levels of innovation in nonprofit organizations, and strategies that foundations are using or can use to encourage innovation in nonprofit organizations. The results showed that among the major motives behind funding innovation were leveraging the capital, honoring the foundations' core identity (mission and values), and desiring to encourage innovation in nonprofit organizations. Five strategies/mechanisms that foundations are using/can use to encourage innovation in nonprofit organizations were identified: (a) offering innovation awards/grants as catalysts for innovation, (b) providing risk capital and supporting early stage idea development, (c) educating other foundations on the value of innovation and serving in a convener role, (d) serving as thought leaders, and (e) increasing nonprofit organizations' capacity for innovation. Implications for practice are discussed along with recommendations for future research.  相似文献

This article sheds light on issues concerning discrimination in the history of deaf people in Sweden in the 20th century. With the help of a specific typology of concepts for analysing discrimination exercised through the use of language, it is shown how the categorization of the hearing impaired has changed over time and how, in this process of change, official discourses on 'deaf-muteness' or deafness has shifted from more to less discriminatory in certain respects and from making deaf people out as very different from the majority population to de-emphasizing differences. The overall social practice is described as moving from assimilation towards inclusion.  相似文献
