孔子“文质观”的古为今用——对电视相亲节目的思考

[摘 要]电视相亲类节目席卷荧屏,形成一股热潮,以文质观这种文论观点来看待此现象,观众的质疑、批评、谩骂,原因在于此类相亲节目过度包装、策划、炒作,而忽视了电视节目本身的内涵,娱乐教育服务功能,可以说是文胜于质。本文欲对《论语》中孔子“文质观”略作梳理,并且通过其之精髓来推进电视节目的良性发展及提供重要的借鉴意义。     

Queer Youth Space: A Protective Factor for Sexual Minority Youth

Physical, psychological, and social vulnerabilities of sexual minority youth are well documented. Yet factors that protect this population from these risks remain relatively unknown. Previous researchers suggest that (1) a sense of safety, meaningful relationships with others, and positive identity development are protective and (2) social support programs focusing on sexual minority youth (Queer Youth Space) have a positive impact. In this article, Queer Youth Space is explored as a program that may promote protective factors and mediate risks. Theories of attachment, self psychology, and social identity are applied to conceptualize Queer Youth Space and its protective roles. Implications for social work practice and research are discussed.     

Evaluation of Support Groups for Child Abuse Prevention: Outcomes of Four State Evaluations

ABSTRACT

Parent support groups have grown in popularity as a strategy for preventing child maltreatment, but there have been few evaluations of these groups. The purpose of this paper is twofold. One goal is to identify some of the major challenges in the evaluation of parent support groups and to provide strategies for minimizing these potential difficulties. The second goal is to illustrate successful evaluations of parent support groups (i.e., the Circle of Parents® program) in four states. Three of these states used a retrospective pretest method. Outcomes indicated positive performance across all domains of functioning, as measured by a self-report questionnaire. Strengths and limitations of the evaluations are discussed, and recommendations for future evaluations are provided.

基于多目标多元学习细菌觅食优化算法的混合数据聚类

针对混合属性数据聚类问题,本文提出一种基于多目标多元学习细菌觅食优化算法。首先,基于改进的细菌觅食优化算法,提出多目标优化算法框架。然后,提出多元学习策略来提高算法性能。具体地,对于细菌个体,细菌之间采用环形拓扑学习策略,每个细菌只能向其邻域最优个体学习;细菌个体还可以向外部档案非支配个体学习。通过该学习策略,不仅可以保持种群的多样性,也可以加快算法收敛速度。对于外部档案非支配个体,记录其变化趋势,当非支配个体的变化处于停滞状态时,采用精英学习策略对非支配个体进行微扰动,提高非支配解的多样性。最后,为解决混合属性数据聚类问题,设计了一种具有属性权重的混合属性转换策略。为了验证所提算法的性能,将该算法与两个多目标进化算法和三个经典聚类算法在六个标准数据集上进行对比实验。实验结果表明,所提算法在解决数值、分类和混合属性数据聚类问题上具有显著优势。同时,以金融领域信用卡申请客户数据为例,进一步证实了所提算法的可行性,也表明了所提算法在涉及混合属性数据集的医疗、管理、工程等领域有一定的应用前景。     

Multilocation plant sizing and timing problem: a study of spatial—temporal decomposition procedure

An attempt has been made to develop a spatial-temporal decomposition procedure to solve the multilocation plant sizing and timing problem (MLPSTP). MLPSTP involves the determination of site, location, timing and utilization of the plants to meet the demands of geographically distributed customers. These decisions are assumed to interact through a common objective of minimizing the net present value (NPV) of capital costs and streams of operating and transportation costs. A solution procedure for MLPSTP is proposed using aggregation and disaggregation methodology. In the aggregation phase, MLPSTP is considered to be a single-period problem. This problem is decomposed over different geographical areas to obtain a set of feasible sites and projects. These projects are then sequenced over a finite planning horizon in the disaggregation phase. A multiple criteria based evaluation of spatial decomposition, temporal decomposition, and spatial-temporal decomposition is provided.     

民族互嵌式社区铸牢中华民族共同体意识的实现路径——基于整体性治理视角

民族互嵌式社区作为推动各民族交往交流交融的空间场域,目的是打破民族交往过程中社会结构的分隔,实现不同民族的良性互动与共同发展。铸牢中华民族共同体意识背景下,探索符合民族互嵌式社区发展实际的治理路径,对于提升民族互嵌式社区现代化治理水平和推动民族地区加快现代化建设步伐具有重要意义。基于整体性治理研究视角,通过对民族互嵌式社区治理的相关研究梳理和整体性治理的理论内涵分析,发现整体性治理所秉持的以民众需求为价值导向,以协调、整合与创新来引导多主体参与协同共治的理念与民族互嵌式社区治理的价值目标存在一定的耦合关系。通过对民族互嵌式社区整体性治理铸牢中华民族共同体意识的逻辑机理分析,提出强化基层党建引领作用、聚焦民族地区经济建设、健全矛盾纠纷化解机制和完善社区现代治理体系的整体性治理路径,为民族互嵌式社区铸牢中华民族共同体意识探索行之有效的实现方式。

首轮退耕还林补贴到期对农户多维相对贫困的影响

基于甘肃、宁夏和湖南三地首轮退耕农户的调研数据,采用A F双界限方法测度退耕农户多维相对贫困发生率,在此基础上借助精确断点回归设计,实证检验退耕还林补贴到期对农户多维相对贫困的影响。结果表明:第一,补贴到期农户各维度及其多维相对贫困发生率均高于未到期农户;第二,补贴到期对相对收入、充分就业、生活水平、主观感知维度及多维相对贫困的局部平均处理效应均显著为正;第三,异质性分析发现,补贴到期对老年和低收入农户多维相对贫困的正向影响效应相对更强。鉴于此,从制定相关保障措施、建立防止返贫的动态监测和帮扶机制以及完善退耕还林后续政策等方面提出相应政策建议。     

Maximum likelihood estimation for the proportional odds model with mixed interval-censored failure time data

This article discusses regression analysis of mixed interval-censored failure time data. Such data frequently occur across a variety of settings, including clinical trials, epidemiologic investigations, and many other biomedical studies with a follow-up component. For example, mixed failure times are commonly found in the two largest studies of long-term survivorship after childhood cancer, the datasets that motivated this work. However, most existing methods for failure time data consider only right-censored or only interval-censored failure times, not the more general case where times may be mixed. Additionally, among regression models developed for mixed interval-censored failure times, the proportional hazards formulation is generally assumed. It is well-known that the proportional hazards model may be inappropriate in certain situations, and alternatives are needed to analyze mixed failure time data in such cases. To fill this need, we develop a maximum likelihood estimation procedure for the proportional odds regression model with mixed interval-censored data. We show that the resulting estimators are consistent and asymptotically Gaussian. An extensive simulation study is performed to assess the finite-sample properties of the method, and this investigation indicates that the proposed method works well for many practical situations. We then apply our approach to examine the impact of age at cranial radiation therapy on risk of growth hormone deficiency in long-term survivors of childhood cancer.
