A nonparametric control chart for variance is proposed. The chart is constructed following the change-point approach through the recursive use of the squared ranks test for variance. It is capable of detecting changes in the behaviour of individual observations with performance similar to a self-starting CUSUM chart for scale when normality is assumed, and a relatively better power when assessing nonnormal observations. A comparison is also made with two equivalent nonparametric charts based on Mood and Ansari-Bradley statistics. When dealing with symmetrical distributions, the proposed chart shows smaller (better) out-of-control average run length (ARL), and a competing performance otherwise. In addition, sensitivity to changes in mean and variance at the same time was tested. Extensive Monte Carlo simulation was used to measure performance, and a practical example is provided to illustrate how the proposed control chart can be implemented in practice. 相似文献

ResumenPresentamos una nueva escala para medir el estrés de aculturación de los autóctonos ante la inmigración, concretamente sudamericana. Hemos partido del concepto de amenaza percibida tomado de la Teoría Integrada de la Amenaza (Stephan y Stephan, 1996). Un análisis de componentes principales realizado con una muestra de 770 participantes ofrece una estructura compuesta por dos dimensiones: estrés de interacción y estrés por recursos. La escala final está formada por 16 ítems más tres de control de la deseabilidad social. Los análisis de fiabilidad han encontrado unos índices de consistencia interna muy satisfactorios, de.91 para la escala general de estrés de aculturación y de.91 y.88 para las dos subescalas. Los datos obtenidos permiten ofrecer un instrumento de medida que constituye una contribución en el estudio de los procesos de aculturación. 相似文献

Parents' socialization goals are important for cultural transmission across generations, but whether such goals vary by ethnic and socioeconomic backgrounds and change over children's first years of life remains unexamined. In Study 1, African‐American, Dominican immigrant, and Mexican immigrant mothers (N = 300) reported on the qualities deemed as desirable or undesirable when children were aged 1 month, 14 months, and 2 years. Mothers spontaneously referred to a common set of qualities, including achievement, self‐maximization, proper demeanor, and connectedness. Most mothers emphasized achievement (desirable qualities) and disapproved of improper demeanor (undesirable qualities). Desirable qualities varied by age and socioeconomic factors more than did undesirable qualities. Mothers (N = 185) were followed up in Study 2 when children were aged three years, and ranked 21 qualities using a Q‐sort instrument. Ethnic differences were revealed at this more specific level, with Latina mothers being more similar in their rankings than African‐American mothers. 相似文献

The global trend of fisheries overexploitation and collapse has resulted in the need to reduce fishing effort, and providing alternative employment for fishermen is a frequently mentioned policy option in order to achieve this goal. Reducing fishing effort is central to the European Commission Common Fisheries Policy and over the years, the Commission has developed a number of socio-economic measures to encourage labour mobility among fishermen, and as such mitigate the impact caused by the structural adjustment. Considering this aim, this paper seeks to identify European fishermen's willingness for occupational and geographical mobility and the characteristics that influence this willingness. A survey was conducted with the participants in the inshore commercial fisheries of the Highlands of Scotland (UK), the Algarve (Portugal) and the South Evoikos Gulf (Greece), and logit models fitted to identify the characteristics that influence willingness for labour mobility. The paper argues that there are differences in attitudes towards labour mobility among fishermen from the different countries and that personal preferences, demographic characteristics, job-related and financial reasons influence the willingness for both occupational and geographical mobility. The paper concludes by pointing out the importance of taking local conditions and the heterogeneity that characterizes fishermen's behaviour into account, in order to achieve successful policy measures aimed at providing alternative occupations for fishermen. 相似文献

This paper reviews the literature of how three aspects of metacognition, relevant to working with children in clinical settings,
develop across childhood. In cognitive therapy children use their metacognition to monitor the recall of thoughts from memory
and to control thoughts as they are actively worked on and restructured. This paper will show that over childhood children
use metacognitive monitoring and control abilities in increasingly complex ways and it will provide the ages at which children
may be consistently using the cognitive abilities necessary to fully benefit from cognitive therapies. 相似文献

Seeking to extend research on public relations evaluation, this study investigates the influence of public relations efforts and media coverage on corporate reputation and financial performance through the theoretical grounding of first- and second-level agenda-building and agenda-setting. A triangulation of research methods compared public relations content, news media coverage, public opinion, and corporate financial performance for 28 U.S. companies from the annual Harris Interactive (2005) Reputation Quotient. Evidence for agenda-building and agenda-setting propositions was found, which work to inform strategies of public relations practitioners. The implications of the findings are discussed. 相似文献

This article reports the findings of a study of perceived barriers to volunteering to formal organizations by nonvolunteers. We examine the types of barriers, their frequencies, and their relationships with individual‐level sociodemographic characteristics of nonvolunteers. Data from a 2001–2002 national survey conducted by the U.S. Bureau of Labor Statistics are analyzed using multiple regression techniques. Contrary to general expectations, only three barriers—lack of time, lack of interest, and ill health—are fairly common. Furthermore, as expected, different social class groups identify different types of barriers. The article concludes with a discussion of the theoretical implications of the findings (for example, how indicators of social and cultural capital affect access to volunteer opportunities) and practical implications concerning recruitment of volunteers. 相似文献

This paper analyses the crosscultural comparability of well-being among 13–20 year-old adolescents using two samples, one from Oran County (Wilaya) in Algeria and another from Catalonia (Spain). The following are used as well-being indicators: a modified version of the original Personal Well-being Index (PWI) (Cummins et al. in Soc Indicat Res 64:159–190, 2003b), a single-item scale on overall life satisfaction (OLS) and a list of complementary items on satisfaction with various life domains. This research tests the original version of the PWI with some changes and two other versions with additional items. Confirmatory factor analyses show good fit statistics for the three versions with the pooled sample of adolescents from the two countries. The multigroup models show that correlations and regressions may be compared between the two samples, but not means, probably due to different cultural response styles among adolescents in the two countries. Structural equation models including OLS also show good fit statistics. When gender and age are included in these models, the former does not show any correlation with PWI11 in either of the two countries, whereas age shows a clearly negative correlation in both. A new version of the PWI with 11 items has shown higher standardized regression coefficients when the items are regressed on OLS and higher R2 and each of the items has shown to contribute with unique explained variance using the pooled sample, although 3 of the original scale items do not show a significant contribution in Algeria. The fact that a multigroup model using this 11-item version shows good fit with constrained loadings when comparing samples from such different cultural and linguistic contexts as Catalonia and Algeria offers new opportunities for international comparative research of adolescents’ subjective well-being. 相似文献

The present article aims to examine the validity and reliability of the Portuguese version of Personal Outcomes Scale the Escala Pessoal de Resultados (EPR). This scale represents an instrument to measure the quality of life (QOL) in people with intellectual disabilities (ID). The study was initiated with the application of international guidelines in cross-cultural adaptation, culminating with an evaluation of 10 experts for the quantitative evidence of the content validity. All EPR’s items were considered relevant and there was a moderated agreement (k > .40) among the experts in the calculation of Cohen’s kappa, finding some coefficients’ that are considered as an excellent agreement (k > .75). In test field, our sample comprised 335 adults with ID on level of intermittent and limited support needs, even as the respective proxies. The scale showed an excellent internal consistency (α = .94). EPR’s construct validity indexes are also reported and discussed. The study provides EPR as a valid instrument for assess the QOL in ID field, and the scale seems to be useful for improvement of Portuguese rehabilitation practices and services. 相似文献
