Knowledge and Skills of Sexual Abuse Prevention: A Study on School-Aged Children in Beijing,China

To examine the level of child sexual abuse prevention knowledge and skills in a sample of school-aged children, a total of 559 children from first to fifth grade were recruited from one primary school in Beijing, China. Participants were asked to finish a questionnaire surveying their knowledge and skills of child sexual abuse prevention. Results showed that accurate rate of knowledge on child sexual abuse prevention were between 44.0% and 80.0%. Percentage of participants having applied the self-protection skills of “saying ‘no,’” “going away,” and “telling adults” properly in hypothetical situations was 57.4%, 28.3%, and 48.3%, respectively. Third-to-fifth graders had a better performance than first-to-second graders, and girls performed better than boys. Findings suggest that Chinese school-aged children are in need of knowledge and skills related to child sexual abuse prevention, and education programs should be developed as soon as possible.     

让农民工享有社会保障、体面劳动和有尊严的生活

完善社会保障和实现体面劳动是全球的共同举措。在我国社会保障制度逐步定型和社会政策日臻完善的今天,加强对农民工的社会保护,完善公共政策和公共管理服务,实现农民工的社会保障权益和体面劳动,是建设服务型政府的需要,也是企业和工会义不容辞的责任。我国《社会保险法》的颁布实施将有利于农民工更好地享有社会保险,实现体面劳动。

民主党派的政治资源主要包括制度性资源、功能性资源、组织性资源、社会性资源和政策性资源,其配置格局与民主党派在我国政治体系以及多党合作制度中的政治定位密切相关.建国以来民主党派政治资源的配置状况,随着中国共产党对民主党派的性质、地位和作用的认识不断深化以及对政党关系定位日渐清晰、准确而日趋合理,其参政领域和选配职数不断扩大.     

A general approximation to quantiles

For many continuous distributions, a closed-form expression for their quantiles does not exist. Numerical approximations for their quantiles are developed on a distribution-by-distribution basis. This work develops a general approximation for quantiles using the Taylor expansion. Our method only requires that the distribution has a continuous probability density function and its derivatives can be derived to a certain order (usually 3 or 4). We demonstrate our unified approach by approximating the quantiles of the normal, exponential, and chi-square distributions. The approximation works well for these distributions.

Bayesian analysis of a multiple-recapture model

In the Bayesian analysis of a multiple-recapture census, different diffuse prior distributions can lead to markedly different inferences about the population size N. Through consideration of the Fisher information matrix it is shown that the number of captures in each sample typically provides little information about N. This suggests that if there is no prior information about capture probabilities, then knowledge of just the sample sizes and not the number of recaptures should leave the distribution of Nunchanged. A prior model that has this property is identified and the posterior distribution is examined. In particular, asymptotic estimates of the posterior mean and variance are derived. Differences between Bayesian and classical point and interval estimators are illustrated through examples.

联网通用与我国银行卡组织的反垄断

作为新兴产业的我国银行卡业发展缓慢,并严重滞后,联网通用问题尤为突出.我国银行业的高度垄断性是阻碍联网通用发展,也是延缓整个银行卡产业规模扩大的重要原因.中国银联作为人民币转接市场唯一的服务机构,其不断受到来自商户和商业银行的垄断质疑,其实施的限制竞争行为也是阻碍联网通用不能有效实现的重要原因.随着银行卡产业的发展,我国银行卡产业亟需反垄断规制.
