We consider a nonparametric autoregression model under conditional heteroscedasticity with the aim to test whether the innovation distribution changes in time. To this end, we develop an asymptotic expansion for the sequential empirical process of nonparametrically estimated innovations (residuals). We suggest a Kolmogorov–Smirnov statistic based on the difference of the estimated innovation distributions built from the first ?ns?and the last n ? ?ns? residuals, respectively (0 ≤ s ≤ 1). Weak convergence of the underlying stochastic process to a Gaussian process is proved under the null hypothesis of no change point. The result implies that the test is asymptotically distribution‐free. Consistency against fixed alternatives is shown. The small sample performance of the proposed test is investigated in a simulation study and the test is applied to a data example.  相似文献

In order to obtain moments for matrix normally distributed variables the moment generating function is differentiated by aid of matrix derivatives. Moments of arbitrary order as well as a recursive relation are obtained. Further, some more details are given for the first four moments  相似文献

The Affect Regulation Checklist (ARC) was designed to capture affect dysregulation, suppression, and reflection. Importantly, affect dysregulation has been established as a transdiagnostic mechanism underpinning many forms of psychopathology. We tested the ARC psychometric properties across clinical and community samples and through both parent-report and youth self-report information. Clinical sample: Participants included parents (n = 814; Mage = 43.86) and their child (n = 608; Mage = 13.98). Community sample: Participants included independent samples of parents (n = 578; Mage = 45.12) and youth (n = 809; Mage = 15.67). Exploratory structural equation modeling supported a three-factor structure across samples and informants. Dysregulation was positively associated with all forms of psychopathology. In general, suppression was positively associated with many forms of psychopathology, and reflection was negatively associated with externalizing problems and positively associated with internalizing problems.  相似文献

Current literature focusing on young people’s digital technology use often reflects concerns that they may live virtual lives and withdraw from locally geographically situated spaces. It assumes the existence of a split between offline and online ‘worlds’ corresponding to ‘real ‘and ‘non-real’ respectively. This article reports research findings on how young people locate new social media technologies in their daily lives with particular focus on the relationship between their online and offline experiences. The voices of the young people guided the research, which found that their social media use contradicts conventional narratives of moral panic about the alleged unreality and fearful dangers of online spaces for young people.  相似文献

Profound changes in global exchanges of goods, ideas, and labor in the 20th century required scholars to critically engage with notions of citizenship, belonging and inclusion. Scholars of globalization initially posited the development of a postnational citizenship, wherein rights are attached to individuals as human beings rather than as members of particular nation‐states. This article questions these theories in light of the evolution of neoliberalism in global markets and the worsening problems of the displaced and rightless. We show that, with the prioritization of market participation as a condition of full inclusion, personhood is not sufficient for belonging or claims‐making. We highlight the effects of the new ‘market citizenship’ on both migrant groups and native‐born minorities, whose inclusion is increasingly based on economic success rather than legal citizenship. We consider the literature on the ways that neoliberalism builds upon historical economic inequalities to distribute citizenship rights to those individuals deemed productive within the current economic system. Finally, we demonstrate that the current citizenship regime, while not anchored in the nation‐state, is very different from early formulations of postnational citizenship.

Australia’s Indigenous population has a markedly younger age structure than its non-Indigenous counterpart. As a result, greater proportions of the Indigenous population are presently at school and approaching tertiary education age, meaning that any declines in gaps between the two populations in terms of educational attainment may be more apparent than real; a reflection of the differing age structures, rather than true improvement. This paper illustrates the argument across the period 1981–2006. It shows first that crude gaps in educational attainment between the two populations in fact increased across the period, for both pre-tertiary (Year 12) attendance and post-school qualifications, after first declining slightly between 1981 and 1991. Using a classic standardization technique it then illustrates how the differences in age structure conceal what would otherwise be greater or smaller gaps. Although most of the age effects are at present small, the findings indicate the increasing optimality of the Indigenous age structure for the gaining of qualifications, and make it imperative that these differences be explicitly acknowledged and built into all policy interventions. Similarly the findings indicate that any such interventions should be carefully monitored for their potential to negatively discriminate on the basis of age structure.  相似文献

The purpose of this study was to examine whether dispositional sadness predicted children's prosocial behavior and if sympathy mediated this relation. Constructs were measured when children (n = 256 at time 1) were 18, 30, and 42 months old. Mothers and non‐parental caregivers rated children's sadness; mothers, caregivers, and fathers rated children's prosocial behavior; sympathy (concern and hypothesis testing) and prosocial behavior (indirect and direct, as well as verbal at older ages) were assessed with a task in which the experimenter feigned injury. In a panel path analysis, 30‐month dispositional sadness predicted marginally higher 42‐month sympathy; in addition, 30‐month sympathy predicted 42‐month sadness. Moreover, when controlling for prior levels of prosocial behavior, 30‐month sympathy significantly predicted reported and observed prosocial behavior at 42 months. Sympathy did not mediate the relation between sadness and prosocial behavior (either reported or observed).  相似文献

Previous correlational research has demonstrated an association between people’s reasons for having sex (i.e., their sexual goals) and their sexual desire and sexual and relationship satisfaction. Across two studies of people in romantic relationships (N = 396) we extend previous research and demonstrate, for the first time, that manipulating the salience of approach sexual goals (i.e., engaging in sex to pursue positive outcomes, such as enhanced intimacy) compared to avoidance sexual goals (i.e., engaging in sex to avert negative outcomes, such as a partner’s disappointment) or a control condition leads people to feel higher sexual desire for their romantic partners and to report higher sexual and relationship satisfaction. In addition, in Study 2 we demonstrate that focusing on approach sexual goals over the course of a week leads people to report more satisfying sexual experiences during that week, as well as higher desire and overall relationship satisfaction, compared to a control group. The current findings advance approach–avoidance theory by providing evidence that it is possible to manipulate people’s sexual goals and, in turn, impact their feelings of desire and satisfaction. Results are promising for the development of interventions to promote sexual and relational well-being.  相似文献

This study examines the anti-incinerator protest in Guangzhou in China. It uses the advocacy coalition framework to analyze the dynamics between Guangzhou Municipal Government and the protesters. The research covers the establishment of a Public Consultative and Supervision Committee for Urban Waste Management in Guangzhou, a public consultative mechanism for waste management, which is a new development in the policy-making process in socialist China. The ultimate plan will be to demonstrate how policy adjustment is not determined solely by the outcome of protests but is also affected by both a decentralized political structure and the socio-cultural foundation. Consequently, the discussion also explores the gradual transformation of public participation in China’s environmental policy.  相似文献
