社会工作专业服务的本土框架和理论依据 ——一项本土专业服务场域的动态分析?

近十年来，在政府的大力推动下，中国社会工作的发展已经由体制外逐渐走进体制内，与体制的融合成为最迫切、最关键的问题，而融合的最基础专业服务场域就是社区。文章针对社区专业社会工作者与居委会动态关联的分析发现：（1）居委会承担着管理和服务双重角色，采取综合管理服务方式，与追求专业服务的社会工作存在不同的服务逻辑；（2）借助项目综合社会工作服务，能够把专业社会工作服务与居委会的综合管理服务融合起来。两种常见的融合方式，一是注重社区整体能力提升的社区社会工作；二是关注专项服务延伸的社区的社会工作；（3）本土社会工作专业服务的理论依据是“双主体（社会工作者和居委会）”的项目综合社会工作服务的场景服务逻辑，有别于西方七八十年出现的注重在实际生活场景中开展的综合社会工作服务逻辑。     

波普尔科学哲学思想对科学教育的影响

以"证伪主义"为核心的波普尔科学哲学在上个世纪成功替代了逻辑实证主义成为科学哲学上的主导,这不仅是科学哲学的一次革命,还对科学教育的科学本质观、科学教学目标和理念,以及科学教育模式等都产生了深远的影响。

Changes in anti-fat weight bias in women after exposure to thin and plus-sized models

We examined whether exposing women to female models with different body sizes lead to changes in weight-based attitudes and whether evaluation focus altered the effects. Female college students (N = 214) were exposed to 22 images of either thin or overweight models. Participants rated models on either appearance or non-appearance characteristics and completed measures of anti-fat attitudes, thin ideal internalization, and demographics. Participants rated thin and overweight models equally attractive and sexy. Viewing overweight models showed a significant reduction in anti-fat attitudes. There were no effects for thin models or evaluation ratings. Discussion focuses on the implications of positive images of overweight individuals on social attitudes.     

从“稻鱼鸭共生”看侗族的原生饮食——以贵州省从江县稻鱼鸭共生系统为例

侗族先民以生产糯稻为主，并利用稻田养鱼鸭，创造了侗族地区“稻鱼鸭共生”的原始有机农业文化经典形式。侗族特有的生存环境和农耕方式，形成了侗族人民食不离酸、喜糯食、喜酒、好鱼、茶饮独特等饮食特点及文化。侗族的原生食品加工方法独特，选料考究，营养价值高，富含各种人体所必需的营养物质，特别是以鱼类为加工原料的侗族酸食富含人体所需的可溶性钙是新鲜鱼食品的16倍以上，“稻鱼鸭共生”系统成为侗族食材的一个重要来源。稻鱼鸭复合系统保证了侗族传统食品的特殊性及无公害性，只有优质的传统原生态食材才能保证传统民族食品的传统性，保护“稻鱼鸭共生”系统不仅为民族食品的传承和发展提供了原料的保障，也为侗族传统食品产业化打下了坚实的原料供给基础。     

《日本遗孤》读后

最近，我有幸读到辽宁作家刘国强的长篇纪实文学专著《日本遗孤》，感受非常强烈。虽然，以往也接触过一些类似题材的作品，但应该说，这本书确有它自身的特色和独具的长处，就我所获得的印象，归纳起来有以下几点：     

Wavelet Estimator in Nonparametric Regression Model with Dependent Error’s Structure

In this article, we consider a nonparametric regression model with replicated observations based on the dependent error’s structure, for exhibiting dependence among the units. The wavelet procedures are developed to estimate the regression function. The moment consistency, the strong consistency, strong convergence rate and asymptotic normality of wavelet estimator are established under suitable conditions. A simulation study is undertaken to assess the finite sample performance of the proposed method.     

基于改进模糊聚类算法的灰色预测模型

目前研究的模糊C均值聚类算法(FCM)面临的最重要问题是初始值随机选取,导致其容易陷入局部最优,同时影响运算速度.而灰色预测GM(1,1)模型在形成预测公式时对初始值的选取也没有合理有效的方案.针对以上问题,文章提出坐标密度法,确定初始聚类中心,对FCM算法进行改进;接着提出运用改进的FCM求取GM(1,1)中数据的聚类中心,并把聚类中心作为初始值的方法;通过与已知算法进行比较验证了其可行性和有效性.     

Depletion Effect of Work-Leisure Conflict: A Daily Diary Study

The negative effect of work-leisure conflict has attracted the attention of researchers. However, no previous research has determined the relationship between work-leisure conflict and ego depletion. Therefore, this study explores the relationship between daily work-leisure conflict and ego depletion, as well as the role of individuals’ negative emotions and core self-evaluations in this process based on ego depletion theory. Through the method of daily diary research, 77 employees were tracked for 7 consecutive work days. The results show that work-leisure conflict is positively related to employee ego depletion, that the negative emotions play a mediating role in this relationship and that core self-evaluations moderate the indirect effect of work-leisure conflict on ego depletion through negative emotions. In this study, daily diary method is used to verify the dynamic characteristics of work-leisure conflict, negative emotions and ego depletion, and some new insights into how to reduce employee ego depletion are provided.

     

学前儿童基于重量和声音进行因果推理的发展研究

儿童的推理能力历来都是考察儿童认知发展的重点。本研究探讨了在多种属性刺激下3~5岁儿童基于重量和声音进行 因果推理的表现。结果发现：4岁和5岁儿童选择正确目标物的准确率显著高于3岁儿童；和同时使用声音与重量判断目标物相 比，儿童在单独使用重量或声音的情况下更容易区分目标物。总之，儿童因果推理能力发展的关键期在4岁并且当任务难度较高 的情况下其因果机制极易受到干扰。
