Two-tailed asymptotic inferences for a proportion   总被引:1,自引:0,他引:1  
This paper evaluates 29 methods for obtaining a two-sided confidence interval for a binomial proportion (16 of which are new proposals) and comes to the conclusion that: Wilson's classic method is only optimal for a confidence of 99%, although generally it can be applied when n≥50; for a confidence of 95% or 90%, the optimal method is the one based on the arcsine transformation (when this is applied to the data incremented by 0.5), which behaves in a very similar manner to Jeffreys’ Bayesian method. A simpler option, though not so good as those just mentioned, is the classic-adjusted Wald method of Agresti and Coull.  相似文献

This study estimates the effects of food hypersensitivity on individuals?? perceived welfare and well-being compared to non-food hypersensitive individuals. Study respondents were recruited in the Netherlands, Poland, Spain and UK. The difference in welfare between food hypersensitive respondents and those asymptomatic to foods was estimated using a subjective welfare approach, including income evaluation. Well-being was measured using the Cantril Ladder-of-Life Scale, and health status using the Self-Perceived Health Scale. The difference in well-being, welfare and health status between participant groups was explained further using a number of background variables. No significant within-country differences in welfare between food hypersensitive respondents and respondents asymptomatic to foods were found. In terms of well-being, adult food hypersensitive respondents and their spouses reported significantly less happiness than respondents and their spouses asymptomatic to foods in the Netherlands and Poland. In Spain, the spouses of the food hypersensitive respondents were significantly less happy than respondents aymptomatic to foods. The well-being of children did not significantly differ between groups. The degree of severity of food hypersensitivity was negatively related to overall health status. In Poland, food hypersensitive respondents reported worse health status compared to asymptomatic respondents. In Spain, the converse was true. Food hypersensitive respondents were generally less happy with their life as a whole than respondents asymptomatic to foods, presumably because they experienced more negative effects, which were not related to perceived health status.  相似文献

Therapeutic residential care (TRC) is the name given to specialized children's homes for treating cases with severe emotional and behavioural problems that have been placed in residential care. A recent international review has revealed great diversity in the referral criteria of cases and in the models of intervention carried out. The goal of this study is to describe the population treated in these types of facilities in Spain and the therapeutic coverage given. The sample is made up of 215 young people in children's homes, of whom 93 are in TRC. The cases referred to TRC have been in residential care for less time but have gone through a greater number of placements. These young people also exhibit more problems of drug use, and there is a larger percentage of clinical‐range cases in the Child Behaviour Checklist scales of attention problems and aggressive behaviour. Nevertheless, the results of logistic regression indicate that the only variables that significantly increase the probability of being referred to TRC are drug use and changes of care placements. With regard to therapeutic care, there is a higher percentage in the TRC group receiving psychiatric care, and the sessions are also more frequent.  相似文献

We evaluate the effects of the European sovereign crisis on Italian potential output (natural output, in the absence of nominal rigidities) by simulating a New Keynesian model. Our results are as follows. First, the 2011–2013 recession subtracted 1.6 percentage points from potential output growth and widened the output gap. Second, the 2013 reforms limited the reduction in output capacity to 1.4 points and enhanced long-run growth by 3. Third, once a balanced budget is achieved in the medium term, reductions in either labor or capital income taxes would boost potential output growth by 0.2 points per year.  相似文献

This article presents a definition and characterisation of the ‘European social model’ (ESM), admitting the existence of variants and increasing heterogeneity in institutional and social contexts within the EU in the wake of successive enlargements. The constituent parts of the ESM are compared with data observed in the different countries, in search of empirical evidence of the ESM‘s position as a distinctive model of development, characteristic of Western Europe as opposed to the paths taken by other non‐European developed OECD countries.  相似文献

ABSTRACT

The occurrence of divorce seems to have impact on parent–child communication, with subsequent implications on the children well-being and development. The present study aims to analyze the influence that divorce has on parent–child communication comparing 102 participants from post-divorced families and 100 participants from intact nuclear families. Measures consisted of a sociodemographic questionnaire and Perception Scale of Parenting Communication. Despite literature indicators, the main findings reveal the absence of significant statistical differences between both family structures, concerning to parent–child communication. Overall, it was registered some statistically significant differences concerning to specific divorce variables. These findings demystifying the idea that post-divorce families establish less positive communication patterns when compared with intact nuclear families.  相似文献

There are multiple factors which contribute to the development of the individual’s personality. Many of these factors have been amply discussed in traditional theories of personality Jonnation. An area that has been neglected in these discussions has been the role that poverty and ethnic and cultural factors may have in this regard. This paper offers a discussion of these issues with special emphasis on cultural, ethnic, and socioeconomic factors which tend to characterize the lives of Latino and Black individuals. Recommendations are made for a re-evaluation of the traditional theories of personality when applied to poor and minority individuals.  相似文献

This study compared the memory, attention/concentration, and executive functioning of 12 women with histories of child sexual abuse with a control group of 12 women without childhood abuse. Participants completed a neuropsychological test battery and various instruments assessing post-traumatic stress disorder and dissociation. The child sexual abuse group had lower performance than the control group on long- and short-term visual and verbal memory and presented more limited performance on executive functioning tasks. Functioning in these areas showed a negative correlation with post-traumatic stress disorder and dissociative symptoms. These findings suggest that child sexual abuse is associated with memory and executive functioning deficits and supports the idea that people with trauma histories and increased post-traumatic stress disorder and dissociation symptoms may have alterations in neuropsychological functioning.  相似文献

Mediterranean-type ecosystems are one of the most affected environments by habitat loss and fragmentation due to urban development, however only few studies have evaluated the effects of urbanization on the biodiversity of remnant fragments in these ecosystems. This study aims to evaluate the effects of urban development over small mammal assemblages inhabiting isolated forest fragments of an urban area of Chilean Mediterranean zone. We compared abundance and richness of small mammal assemblages of six remnant fragments within an urban matrix, and six fragments similar in area and habitat characteristics with those of urban area, but surrounded by a rural matrix. We found that small mammal assemblages differ considerably among fragments types (urban vs rural), with lack of endemic species from urban fragments and with high proportion of introduced rodents in urban fragments. Furthermore abundance of small mammals was higher in rural than in urban fragments. In urban areas small mammal abundance and richness were not correlated with any of the explanatory variables assessed (woody cover, flora heterogeneity, fragment area, perimeter/area ratio). However in rural fragments small mammal richness was negatively correlated with flora heterogeneity and the abundance of small mammals was positively correlated with perimeter/area ratio. These results reveal important differences within the effects of fragmentation over small mammal assemblages among the two types of fragments assessed. Our findings suggest that in forest fragments isolated by urbanization, larger areas with good quality habitats are not sufficient to maintain native small mammal population.  相似文献
