Likelihood procedure for testing changes in skew normal model with applications to stock returns

The skew normal distribution family is an attractive distribution family due to its mathematical tractability and inclusion of the normal distribution as the special case. It has wide applications in many applied fields such as finance, economics, and medical research. Such a distribution family has been studied extensively since it was introduced by Azzalini in 1985 Azzalini, A. (1985). A class of distributions which includes the normal ones. Scandinavian Journal of Statistics 12:171–178. [Google Scholar] for the first time. Yet, few work has been done on the study of change point problem related to this distribution family. In this article, we propose the likelihood ratio test (LRT) to detect changes in the parameters of the skew normal distribution associated with some asymptotic results of the test statistic. Simulations have been conducted under different scenarios to investigate the performance of the proposed method. Comparisons to some other existing method indicate the comparable power of the method in detecting changes in parameters of the skew normal distribution model. Applications on two real data: Brazilian and Tanzanian stock returns illustrate the detection procedure.     

Presence and process of fear of birth during pregnancy—Findings from a longitudinal cohort study

Background

The prevalence of fear of birth has been estimated between 8–30%, but there is considerable heterogeneity in research design, definitions, measurement tools used and populations. There are some inconclusive findings about the stability of childbirth fear.

Impact of a continuing professional development intervention on midwifery academics’ awareness of cultural safety

Background

Cultural safety in higher education learning and teaching environments is paramount to positive educational outcomes for Aboriginal and/or Torres Strait Islander (hereafter called First Peoples) students. There is a lack of research evaluating the impact of continuing professional development on midwifery academics' awareness of cultural safety.

Mighty Crime Victims: Victims' Rights and Neoliberalism in the American Conjuncture

Over the last 30 years, the victims' rights movement has expanded the role of victims in the American criminal justice system. As a result of this movement, judges, prosecutors and parole boards must now hear victims' views at all stages of the criminal justice process, including plea bargains, and sentencing and parole decisions. Legislative efforts have been spearheaded by victims' families, and legislation has been named after deceased victims. Also, victims' families can now view executions in states across the country. The victims' right movement assumes that the criminal justice system should privilege victims' interests over those of society. In so doing, it denies society as a consideration, which is tantamount to a denial of society itself. This article positions victims' rights' denial of society within the current conjuncture, marked as it is by the contradiction between neoliberalism and American liberalism. Victims' rights' denial of society is an expression of the denial of society implicit in American neoliberalism, which seeks to privilege individual interests over those of society. This paper argues that victims' rights is a powerful element of the neoliberal project for three reasons. First, victims' rights imputes the authority of legal discourse to neoliberalism's denial of society. Second, important actors in the rise of neoliberalism have also worked to establish victims' rights. Finally, victims' rights comprehensively circulates throughout America and offers powerful points of identification that incorporate Americans into the victims' rights formation. I explore the denial of society in three victims' rights practices: naming criminal legislation after crime victims and passing such laws in honour of victims; allowing victims' families to view executions; and prosecutors, judges and police personnel making legal decisions according to victims' wishes. I examine the consonant denial of society in three neoliberal practices – monetarism, supply-side economics and welfare reform – and demonstrate how neoliberal advocates like Bill Clinton, Ronald Reagan and Paul Gann worked to advance victims' rights. I also describe the production, consumption and comprehensive circulation of victims' rights texts. Finally, I consider Cultural Studies' unique contribution to legal studies.     

Organizational characteristics that foster early adoption of cultural and linguistic competence in outpatient substance abuse treatment in the United States

Recent years have seen an increased interest in developing culturally and linguistically responsive systems of care in substance abuse treatment in the United States. This study examines the extent to which external and internal organizational pressures contributed to the degree of adoption of culturally and linguistically responsive practices in the nation's outpatient substance abuse treatment system early in the period of development of this system of care. Findings show that a higher degree of adoption of culturally competent practices was most likely in treatment programs with high dependence on external funding and regulation. Internally, programs with a larger number of professionals were associated with the lowest degree of adoption, while managers’ cultural sensitivity contributed significantly to a high degree of adoption of these responsive practices. Considering the passage of recent legislation enforcing the use of cultural and linguistic competence in health care, implications of these baseline findings on early adoption patterns are discussed for future research and health care policy evaluation.     

Predictors of treatment outcome in a child and adolescent psychiatry clinic: A naturalistic exploration

We present data on predictors of treatment outcome for 3200 consecutive referrals to a child and adolescent psychiatry clinic. Using Reliable Change Index (RCI) methodology, we divided children into those who, between intake and discharge, improved, stayed the same, or got worse according to clinician-rated impairment. Most predictors of improvement were related to parent variables (marital status, maternal anxiety, and ethnicity), while those associated with deterioration were tied to child status (extent of psychiatric comorbidity, history of placement in a self-contained classroom, and a prior trial of psychotropic medications). The implications of these findings for data-driven program development, clinic management, treatment planning, and systems of care are discussed.     

胡耀邦与“文化大革命”后拨乱反正时期的青年工作

胡耀邦同志在“文化大革命”后这个特殊的年代,对青年工作面临的基本问题,包括对“文化大革命”后青年的估价,青年工作拨乱反正的任务和基本方针,处理“文化大革命”遗留下来各种严重的青年问题的方针和政策,对当时的共青团组织怎样工作和团干部应有的精神状态与作风等,都有相关的系统论述。这是我党青年工作的一个典范。青年是社会变革中一支最敏感、最活跃也是很重要的力量,今天我们重温胡耀邦同志当时的指导思想,仍有着重要的现实意义。     

气候变化政治对海湾国家的影响

海湾地区气候炎热,淡水资源缺乏。长期以来,海湾国家主要依靠能源出口获取大量资金,借此修建海水淡化工厂等各种设施以适应和改善气候环境的影响。近年来,国际社会在应对全球变暖问题的协调合作中,已形成一种处理全球气候变化的政治。气候变化政治要求各国减少能源消耗和降低二氧化碳排放量以缓解全球变暖趋势,从而对海湾国家以能源出口收益来维护生存环境和社会稳定的基本经济模式构成冲击。面对气候变化政治带来的冲击,海湾国家目前的权宜选择只能是继续扩大能源出口,并尽量拖延实施气候变化协议来进行应对。然而,这种做法虽可以暂时保持海湾国家改善环境的努力和维护其经济政治结构稳定,但却难以消除全球气候变化政治今后长期推动能源结构调整和节能减排所带来的压力。     

伊盟、伊合与中国中东人文外交

伊斯兰世界联盟与伊斯兰合作组织是泛伊斯兰主义制度化的产物,伊盟主要通过朝觐平台间接对伊斯兰国家政治施与影响,伊合则通过推进议题的方式直接对伊斯兰国家政治产生影响;我国历来重视发展与这些泛伊斯兰国际组织的友好关系,并取得了宝贵历史经验与良好的成效;在明确我国与泛伊斯兰国际组织开展人文交流与合作的资源优势、基本目标及其实现途径的基础上,探索我国对中东国家开展“全方位、多层次、宽领域”人文外交的应对之策,旨在进一步提升我国对中东伊斯兰国家的人文外交能力.
