The objective of the current study was to explore the estimated prevalence of childhood sexual abuse in China. We conducted a meta-analysis that used the data from 36 articles. A total of 125 independent samples and 131,734 participants were included. The results revealed no significant difference in the prevalence of childhood sexual abuse between Chinese men (9.1%) and women (8.9%). The prevalence of childhood sexual abuse in studies from mainland areas was significantly higher than that from Hong Kong/Taiwan. The estimated prevalence of childhood sexual abuse in China also differed according to the definition of child sexual abuse, data collection method, year of data collection, and the mean age of participants at the time of assessment. 相似文献

This scoping review followed Cochrane guidelines to comprehensively assess the use and understanding of Evidence-Based Practice (EBP) in Chinese social science literature. We conducted a research across three electronic databases and three major social science journals for the studies published between 2004 and 2016. Chinese social work literature demonstrates a precise understanding of EBP defined as a process, but it lacks comprehensive discussions about EBP that extend beyond basic principles and process definitions. We identified language barriers and developmental issues for social work in China that contribute to these incomplete discussions. We examined the importance of broadening and enriching the discussions around EBP, especially for Chinese educators, researchers, and clinicians involved with empirically supported treatments. We also consider the implications of our findings for the development of social work in China. 相似文献

近年来,我国农业保险快速发展,在保费收入、保障范围和参保农户数量等指标上都取得了举世瞩目的成绩。与此同时,保障水平不高、农业保险“不解渴、不顶用”也一直是各方反映的焦点之一。本文结合了福利经济学和保险经济学中的相关理论,遵循“提高农业保险保障水平必须优化其财政补贴政策”的逻辑主线,对实施财政补贴政策是提升农业保险保障水平的前提条件、有效途径、有力举措和重要渠道进行了梳理和评析。最后,针对现有研究的不足,结合当前的时代背景,对该领域日后的研究重点进行了预测,并进一步探讨了其优化路径。 相似文献

便宜原则在我国行政处罚法上并无明文的依据,但在行政实务中却不乏采用。基于合理行政的要求,在行政处罚法上应当承认便宜原则。便宜原则作为法定原则的一种补充,应仅于特殊情形下适用。由于便宜原则授予了行政机关更加宽泛的自由裁量权,因此其在适用时必须受到严格的约束。在将来修订行政处罚法时,有必要对便宜原则作出明确的规定。 相似文献

In this paper, a compound Poisson risk model in the presence of a constant dividend barrier is considered. Two types of individual claims, main claims and by-claims, are defined, where every by-claim is induced by the main claim and and the time of delay for the claim is assumed to be random. A system of integro-differential equations with certain boundary conditions for the expected discounted penalty function is derived. We show that its solution can be expressed as the solution to the expected discounted penalty function in the same risk model with the absence of a barrier plus a linear combination of two linearly independent solutions to the associated homogeneous integro-differential equation. Using systems of integro-differential equations for the moment-generating function as well as for the arbitrary moments of the sum of discounted dividend payments until ruin, a matrix version of the dividends–penalty type relationship is derived. We also prove that ruin is certain under constant dividend barrier strategy. The closed form expressions are given when the claim amounts from both classes are exponentially distributed. Finally, a numerical example is presented to illustrate the solution procedure. 相似文献

We consider the compound Markov binomial risk model. The company controls the amount of dividends paid to the shareholders as well as the capital injections in order to maximize the cumulative expected discounted dividends minus the discounted capital injections and the discounted penalties for deficits prior to ruin. We show that the optimal value function is the unique solution of an HJB equation, and the optimal control strategy is a two-barriers strategy given the current state of the Markov chain. We obtain some properties of the optimal strategy and the optimal condition for ruining the company. We offer a high-efficiency algorithm for obtaining the optimal strategy and the optimal value function. In addition, we also discuss the optimal control problem under a restriction of bounded dividend rates. Numerical results are provided to illustrate the algorithm and the impact of the penalties. 相似文献

More than 75% of Fortune 500 companies have established models of shared services with the aim of gaining superior performance by cost savings and service enhancements. Despite scholars' complaints about scant shared service center (SSC) research, this study shows that the actual shortcoming in this stream concerns a high fragmentation of the academic literature (e.g., we found 137 works in the initial search and 83 works in a refined screen). In this first comprehensive literature review, we synthesize peer-reviewed articles and classify them into 4 perspectives according to their research questions (i.e., determinant, process, control, and outcome). We identify 17 major research areas across these perspectives. Additionally, we provide information on methodologies and theories. On the basis of the literature synthesis, we discuss opportunities and gaps and propose an agenda for future research. Specifically, we suggest 3 potential research directions (i.e., direct relationships, mediating, and outcome effects) regarding SSCs during their operational maturity phase. 相似文献
