Experimental studies focusing on the socialization role of parental authority exertion in persistent rule‐breaking contexts involving non‐personal issues have recently shown the advantages of using logical consequences over alternative strategies (mild punishments, reasoning, and no‐authority). Using an experimental vignette approach and a sample of 214 adolescents (Mage = 15.28 years), the present study extended these findings by comparing the same parental interventions in a rule‐breaking setting involving a multifaceted issue. Specifically, and based on research anchored in social domain theory, we evaluated how adolescents' perceptions of the issue underlying the multifaceted transgression (personal vs. non‐personal) moderated the effects of authority exertion strategies on socialization indicators. When adolescents perceived the transgression as a non‐personal issue, past results were replicated and enhanced. Adolescents rated the logical consequence as at least as effective as the mild punishment to prevent future transgressions (i.e., more so than reasoning and no‐authority) and as the most acceptable strategy. Furthermore, contrary to the mild punishment, they did not perceive the logical consequence as more autonomy‐thwarting than reasoning. In contrast, adolescents who categorized the transgression as a personal matter rated the logical consequence less favorably, leaving reasoning as a preferred form of intervention. Implications for optimal parenting are discussed.  相似文献

This article analyses the complex legislative and judicial processes that would be required to establish the right to co‐parenting in the Italian labour regulation system. Identifying a trend in the Italian legal system that has so far limited family protection to the support of women and maternity, the author then elaborates on the legislative evolution that has led to the acknowledgment of fathers as key partners in their children's upbringing. Lastly, an analysis of case law shows how this has been used to give a modern interpretation of legislated principles, providing a crucial contribution to overcoming the ongoing resistance to these processes from a male‐oriented culture.  相似文献

The aim of this paper is to introduce new statistical criteria for estimation, suitable for inference in models with common continuous support. This proposal is in the direct line of a renewed interest for divergence based inference tools imbedding the most classical ones, such as maximum likelihood, Chi-square or Kullback–Leibler. General pseudodistances with decomposable structure are considered, they allowing defining minimum pseudodistance estimators, without using nonparametric density estimators. A special class of pseudodistances indexed by α>0α>0, leading for α↓0α0 to the Kullback–Leibler divergence, is presented in detail. Corresponding estimation criteria are developed and asymptotic properties are studied. The estimation method is then extended to regression models. Finally, some examples based on Monte Carlo simulations are discussed.  相似文献

This paper studies the asymptotic properties of the quasi‐maximum likelihood estimator of (generalized autoregressive conditional heteroscedasticity) GARCH(1, 1) models without strict stationarity constraints and considers applications to testing problems. The estimator is unrestricted in the sense that the value of the intercept, which cannot be consistently estimated in the explosive case, is not fixed. A specific behavior of the estimator of the GARCH coefficients is obtained at the boundary of the stationarity region, but, except for the intercept, this estimator remains consistent and asymptotically normal in every situation. The asymptotic variance is different in the stationary and nonstationary situations, but is consistently estimated with the same estimator in both cases. Tests of strict stationarity and nonstationarity are proposed. The tests developed for the classical GARCH(1, 1) model are able to detect nonstationarity in more general GARCH models. A numerical illustration based on stock indices and individual stock returns is proposed.  相似文献

Although researchers, service providers, and clients are determined to improve partnerships within disability services, a lack of partnership persists. Using our research as a case study, we reflect on three limitations of common research methods and social change techniques in this area. We suggest that typical approaches struggle to move beyond taken-for-granted ideas, common-sense solutions, and established ideology in the field of disability. Consequently, they often fail to reveal important barriers to collaboration, identify innovative solutions, or initiate meaningful improvements in partnership. We propose a new approach to partnership research and reform grounded in a pragmatic model of social change and argue that projects based on isolated or simplistic data, majority-rule decision-making, simple and efficient planning, and restricted inside perspectives (where storytelling is limited) must be complemented by observational studies, socio-cultural analyses, and critical investigations. In short, we must understand why working relationships do not change to improve disability services.  相似文献

If foster care primarily concerns foster children displaced from a family to another, it also constitutes a singular event for the entire family, including the children of the foster parents. The aim of this study was to examine anxiety and depressive symptoms in foster families’ birth children and to explore the statistical associations between the different types of horizontal relations (with a sibling or a foster child) and the psycho-affective equilibrium of the birth children. Self-evaluation scales on the quality of sibling relations, anxiety and depressive symptoms were used. Forty five birth adolescents, aged from 11 to 18 years old, took part in the study. These participants showed more balanced scores of anxiety and depression than the population of the same age. Post-hoc tests additionally suggest that these ones vary depending on the gender, possibly due to specific role expectations. The relations between siblings or with the foster child present differentiated outcomes on anxiety and depression scores. This study confirms that the quality of horizontal relations is important for the psycho-affective equilibrium of the birth child. The relationships between birth and foster children need to be more systematically considered in order to promote successful fostering.  相似文献

This paper investigates the problem of prediction of stellar parameters, based on the star's electromagnetic spectrum. The knowledge of these parameters permits to infer on the evolutionary state of the star. From a statistical point of view, the spectra of different stars can be represented as functional data. Therefore, a two-step procedure decomposing the spectra in a functional basis combined with a regression method of prediction is proposed. We also use a bootstrap methodology to build prediction intervals for the stellar parameters. A practical application is also provided to illustrate the numerical performance of our approach.  相似文献

The double‐edged nature of modern technology, continuously balancing between risks and opportunities, manifests itself clearly in an emerging societal problem known as cyberbullying. To analyse the extent and nature of the issue in Belgium, 1318 adolescents were questioned explicitly about their involvement in cyberbullying, as well as implicitly about their experience with specific types of cyberbullying‐related behaviour. This alternate questioning revealed higher victimisation and perpetration rates. The study also provides better insight into predictors associated with victimisation or perpetration in cyberbullying. Especially past involvement in cyberbullying and engaging in online risk behaviour increase the likelihood of victimisation; non‐rejection of cyberbullying and online identity experimentation augment the likelihood of perpetration. Girls are more likely to become victims of cyberbullying, whereas boys are more inclined to engage in electronic bullying. Moreover, the incidence of cyberbullying increases slightly with age. Finally, teens spending much time on the Internet, reporting higher ICT expertise and owning a computer with privileged online access share an increased likelihood of online bullying behaviour.  相似文献
