The purpose of this study was to explore health care professionals' perspectives on elder abuse to achieve a better understanding of the problems of reporting and to generate ideas for improving the detection and reporting process. Through a mailed survey, nurses, physicians, and social workers were invited to participate in an interview. Nine nurses, 8 physicians, and 6 social workers were interviewed, and thematic analysis was used to identify the following core themes: preconceptions, assessment, interpretation, systems, and knowledge and education. Participants suggested a reorganization of the external reporting system. More frequent and pragmatic education is necessary to strengthen practical knowledge about elder abuse.  相似文献

This article examines the prevalence of asthma among New York City households from 10 racial/ethnic groups, and it explores whether differential exposure to potentially adverse housing and neighborhood conditions helps to mediate observed disparities. After adjusting for household size, Puerto Rican households exhibit the highest levels of asthma, followed by other Hispanic and black households. Mexican, Chinese, and Asian Indian households exhibit the lowest levels of asthma. Results from multilevel logistic regression models indicate that exposure to deteriorated housing conditions and perceptions of low social cohesion in the neighborhood significantly elevate the odds of asthma. Controlling for these conditions along with household characteristics reduces the disproportionately high levels of asthma among Puerto Rican and black households, although they remain significantly higher than the level among white households.  相似文献

In this study the authors address the quality of abstracts reviewed during a systematic review. Their objective was to describe the proportion of abstracts that could not be coded and to explore factors associated with that outcome. Using an exploratory design, a database of titles uploaded for analysis was examined for clarity, type and year of publication, and abstract format. Of the 1851 references examined, 481 (26%) were coded as unclear. The inter-rater reliability Kappa score was 0.777. These abstracts were more likely to have been published prior to 2002 and did not use a structured format. Abstracts are an important tool in the systematic review process. Structured abstracts can reduce the time and costs associated with conducting a systematic review.  相似文献

Abstract

Collegiate American football players may be at risk for cardiovascular disease. Objective: To compare cardiovascular disease risk factors and cardiovascular structure and function parameters of football players, stratified by position, to a group of sedentary, nonathletes. Participants: Twenty-six collegiate football players and 13 nonathletes participated in this study. Methods: Blood pressures, anthropometrics, and blood chemistries were obtained and analyzed using standardized procedures. Resting echocardiography was used to evaluate cardiac morphology and function. Brachial artery flow-mediated dilation was assessed using high-resolution ultrasonography. Results: The prevalence of the metabolic syndrome was significantly higher amongst the linemen compared to the skill-position players (46% versus 0%, p < .05). Mildly abnormal wall thickness was noted in 20% of the football players. No significant differences in vascular function were observed between the groups. Conclusions: The increased prevalence of the metabolic syndrome and its components in the collegiate linemen may increase cardiovascular disease risk.  相似文献

Non-parametric Quantile Regression with Censored Data   总被引:1,自引:0,他引:1  
Abstract.  Censored regression models have received a great deal of attention in both the theoretical and applied statistics literature. Here, we consider a model in which the response variable is censored but not the covariates. We propose a new estimator of the conditional quantiles based on the local linear method, and give an algorithm for its numerical implementation. We study its asymptotic properties and evaluate its performance on simulated data sets.  相似文献

Summary. The Transactions of the Statistical Society of London (1837) appeared before the journal of the Royal Statistical Society began publication and represents the substantial statistical work that had been undertaken in the early years of the existence of the Society. The contents of this publication are summarized here against the historical background of the time.  相似文献

Summary. Construction on, or in, the ground is affected by uncertainty. This includes the inherent variability of the ground itself, the effect of natural and human processes on the ground and the difficulties that are associated with the management and implementation of any construction works. The risk is considered to be in two parts: the probability of occurrence of a geohazard and the effect that this will have on the outcome of the project. Geohazards are determined as part of the ground investigation process, the principles of which are well established. Nevertheless uncertainty remains and communication between the professions and with the public is not always effective. Barriers are created by unfamiliar terminology and a lack of a forum for education and exchange of views. It is argued that the public must be continually involved—not only as recipients, but also as contributors.  相似文献

Self-control refers to the process by which individualsconsciously decideto take charge of their own behaviour. This process in prompted by situations in which automatic and habitual responses are interrupted or are ineffective. There are three major functions of self-control behaviour. The first function is redressive and is directed at controlling responses (such as anxiety, pain, ets.) that interfere with the normalfunctioning of the person. This function is improtant for coping with stress. The second function is reformative; it facilitates the adoption of new behaviours that have a low probability of occurence. In this category are included behviours that require delay of gratification and resistance of temptations (such as dieting, quitting smoking, etc.).These two functions were mentioned earlier in theorizing of the self-control process.A third and a new function of self-control is introduced here: experiential self-control. This enables the person to fully experience pleasurable activities (such as listening to music and enjoying a party). This paper discusses phenomena such as relaxation, hypnosis, 'absorption', and 'openness to experience' as situations that call for experiential self-control. It emphasizes the importance of this function for the growth and development of the individual. Highly resourceful individuals possess a repertoire of behaviours that enables them to maintain stability in the face of stress and promote changeby opening themselves to new experiences.  相似文献
