What influences the size of child maintenance payments? A register‐based study of maintenance payments in Finland

The aim of this study was to explore how particular economic and demographic factors contribute to the level of the child maintenance payment (CMP) paid by the non‐resident parent. For this study, we used 5‐year longitudinal panel data from years 2009 to 2013 consisting of over 80,000 non‐resident parents from the Finnish Tax Administration and The Finnish Population Register Centre. Results from regression models indicate that the single biggest factor affecting the size of CMPs is the number of dependent children. We found that the non‐resident parent's higher income is associated with higher CMPs and that non‐resident fathers pay on average larger CMPs than non‐resident mothers, even after accounting for differences in income. Unexpectedly, we found that the age of the dependent child did not predict changes in CMPs. This suggests that once formal CMP‐contracts are determined between the parents, they are seldom changed. Our results suggest that some degree of mandatory periodic review for maintenance contracts is worth considering.     

Optimal scheduling replacement policies for a system with multiple random works

From the economical viewpoint in reliability theory, this paper addresses a scheduling replacement problem for a single operating system which works at random times for multiple jobs. The system is subject to stochastic failure which results the imperfect maintenance activity based on some random failure mechanism: minimal repair due to type-I (repairable) failure, or corrective replacement due to type-II (non-repairable) failure. Three scheduling models for the system with multiple jobs are considered: a single work, N tandem works, and N parallel works. To control the deterioration process, the preventive replacement is planned to undergo at a scheduling time T or the job's completion time of for each model. The objective is to determine the optimal scheduling parameters (T^* or N^*) that minimizes the mean cost rate function in a finite time horizon for each model. A numerical example is provided to illustrate the proposed analytical model. Because the framework and analysis are general, the proposed models extend several existing results.     

信息碎片化时代新媒体在高校主流价值维护中的运用——以民族高校官方微信为例

信息碎片化的时代，新媒体成为形塑学生世界观的重要工具。民族高校经以学校官方微信为龙头的新媒体宣传矩阵，从新媒体工作意识、运行机制、品牌竞争角度形成了成熟的工作机制，通过面向主体诉求的选题、高效的传播形式设计、交互传播方式选择，获得了新的话语优势。民族高校将新媒体建设导向思政工作，使新媒体的传播力变成一种教育力。新媒体通过提供一个合适的议题，让学生在参与议题的过程中去认识问题，由议程设置引导主流价值观形成。民族高校的新媒体依靠塑造共同体意识，对群体成员的价值观和行为形成约束力，使得主流价值得以巩固，学生的媒介素养得以提升，学生在面向复杂环境时，具备了更强的鉴别能力，在维护主流价值观时更加坚定。     

Factor Structure and Reliability of the Advantages of Children Scale with Latino and Caucasian Male Emerging Adults

Abstract

Based on the value of children theory, the purpose of this study was to develop and establish the factor structure and internal consistency reliability of the Advantages of Children Scale (ACS), a self-report measure of a modification of Hoffman and Hoffman’s value scheme of the psychological needs children meet for their parents. Data were collected from 685 emerging adult men identifying as Latino or Caucasian who were not parents. Results of the confirmatory factor analysis found a good fit for the six hypothesized subscales on the ACS: connectedness, expansion of self, family heritage, adult status and social identity, development of self, and family maintenance. We discuss potential applications of the measure in research and practice.     

Impact of an Overt Response System on Staff Performance and Maintenance of Computer-Based Instruction

Interactive Computer Based Instruction (CBI) systems involve teaching strategies to facilitate greater response opportunities during training in an effort to improve learner performance. The current study investigated the effect of online staff training videos with and without overt response requirements on posttest and maintenance test scores across six block-randomized instructional modules for four employees of a university located in the southeastern region of the United States. The overt response consisted of multiple-choice questions administered throughout select teaching modules using an alternating treatment design. Findings suggest that learning occurred as a result of the CBI training; however, the effectiveness of the overt response system varied across individuals, with no discernible differentiation between learning gains associated with response requirements. Other areas of research for expanding the efficacy of CBI and overt response systems are highlighted.     

社会转型与观念变迁--以“道德缺失”为中心的考察

尽管“道德缺失”是转型期中国一个不容忽视的社会问题，但当代的“道德缺失”现象并非严重到了危机阶段，中国古代也不是“道德天堂”。今天的道德困境可以归因于社会环境的巨大变化。这种问题的解决，需依靠有效的维护机制作为保障。落实到根本，还是要大力发展经济，建设市民社会。

关系保持策略量表在中国人群中的初步试用

为了满足亲密关系的研究和婚姻家庭心理咨询的实际需要，对国外该领域中广泛采用的“关系保持策略量表”（RMSM）进行了翻译和修订，并使用一个包含246名被试的样本对该量表的信效度进行了检验。统计分析表明，修订后的中文版RMSM具有较高的信度和效度，符合心理测量学的基本要求。使用中文版RMSM，以818名已婚人士为研究对象，对中国人的关系保持策略特点进行了调查。结果表明：性别、文化程度、家庭收入、年龄、结婚年限、子女等因素都会影响中国人婚姻关系保持策略。     

南海地缘形势与中国政府对南海权益的维护——以20世纪六七十年代南海争端为考察中心

20世纪六七十年代,美、前苏联出于争夺世界霸权的需要,对南海争端采取了不同的政策,南海地区＂边缘地带＂特性进一步凸显。在此背景下,菲律宾、越南和马来西亚等国强占南海岛礁、瓜分海域、掠夺资源。在维权斗争中,中国政府不断地进行南海诸岛主权宣示,抗议周边国家对中国海洋国土主权的践踏,收复被占西沙岛礁,并采取切实措施加强海疆国防建设。
