In Search of Exotic Particles

<正>Looking for"exotic matter"is an important task for high energy physics in the post-Higgs era.Using data from the BEijing Spectrometer(BESIII),researchers have observed a family of particles which contain at least four quarks,providing strong evidence for the existence of unconventional forms of matter.The discovery of Zc particle family For Dr.SHEN Xiaoyan,Dr.YUAN Changzheng and their colleagues at the Institute of High Energy Physics(IHEP),Chinese Academy of Sciences,the year 2013 was     

Child behaviors as a moderator: Examining the relationship between foster parent supports,satisfaction, and intent to continue fostering

Foster parents need access to supports and resources in order to be satisfied with their caregiving role and continue providing foster care services. However, they often experience multiple demands in their role as a substitute caregiver that could lead to stress. Child behaviors especially may be a significant factor when considering sources of strain and may be a potential risk factor for negative outcomes such as dissatisfaction or the decision to discontinue providing foster care. The purpose of this study was to examine whether child disruptive behaviors moderated or influenced the nature or strength of the relationship between foster parent supports and satisfaction as a caregiver as well as intent to continue fostering. The sample consisted of 155 licensed foster caregivers from across the United States. Child behaviors served as a significant moderator between some types of supports and satisfaction. Implications for future research, practice, and policy are discussed.     

Psychological complaints reported by sexually abused children during criminal investigations: Istanbul example

The present study aims at describing the psychological complaints reported, as a part of the criminal investigation process, by the victims of sexual abuse as a part of the criminal investigation process, without attempting at reaching a medical diagnosis; and it discusses the relation of these reports with variables such as victim's gender, age and relation to the offender, type and duration of abuse, and parental marital status of the victim. Data is obtained from the statements of childhood sexual abuse (CSA) victims under the age of 15, as taken by Istanbul Juvenile Justice Department between the years 2009 and 2012. The sample consists of 175 cases with a total of 202 victim statements. Through the use of content analysis, the main and sub-categories of themes of the statements were determined. By means of the evaluation of the psychological condition of victims, we evaluated them in two categories: psychological complaints including self-harm and risk taking behaviors and psychological complaints with no self-harm and risk taking behaviors. The statistical analyses yield significant relations between the psychological complaints and children's parental marital status. Analysis of initial statements of sexual abuse victims is important as it may greatly contribute to professionals diagnosing and treating psychological complaints of these victims. It is essential that victims of sexual abuse should receive immediate psychological support starting with the criminal investigation process.

Joint trajectories of behavioral,affective, and cognitive engagement in elementary school

The aim of the present study was to model student trajectories of behavioral, affective, and cognitive engagement from Grade 3 to Grade 6. The authors also examined whether teachers perceptions could predict student trajectory membership. The authors collected data from a sample of 831 students and 152 teachers. Using multiple-process growth mixture modeling, they identified 5 distinct trajectories of student engagement. Although a large majority of children presented a stable and high level of engagement on the three dimensions over time, more than one third of them showed a lower or changing level of engagement as the years progressed. These students were more likely to be boys and to be perceived by teachers as being less engaged. They also present more learning or behavioral problems and share less positive relationships with teachers. The results support the need to consider group-based differences when designing and adapting prevention and intervention strategies to favor student engagement.     

Spillover effects in environmental behaviors,across time and context: a review and research agenda

When implementing environmental education and interventions to promote one pro-environmental behavior, it is seldom asked if and how non-target pro-environmental behaviors are affected. The spillover effect proposes that engaging in one behavior affects the probability of engagement or disengaging in a second behavior. Therefore, the positive spillover effect predicts that interventions targeting one specific behavioral have the capacity to promote non-targeted and/or future pro-environmental behaviors. However, the negative spillover effect predicts that engaging in a first pro-environmental behavior will prevent or decrease a second pro-environmental behavior. Since the theoretical and empirical basis for positive and negative spillover effects are not sufficiently understood, the present paper (1) suggests a distinction between behavioral, temporal, and contextual spillovers (2) reviews the existing spillover research literature across a variety of environmental domains, (3) presents potential moderators governing the direction of spillover effects, and finally (4) discuss techniques to promote pro-environmental spillovers.

体育义务的内涵

在义务、法律义务概念再认识的基础上,提出体育义务是指体育法律规定的对体育法律关系主体作为和不作为行为的约束,其本质不仅体现体育法的核心价值——"公平"要求意义上的"应当",而且体现法律要求意义上的"应当";其构成要素主要包含体育义务主体、"应当"的体育行为。同时认为,对不同体育主体体育义务进行规定的体育法律包括体育国际法、体育国家法、体育固有法、体育行业协会以及体育权威机构颁布的体育法规。其中,体育固有法对体育行为具有直接的约束力,而体育国家法是保证实现体育义务的最后保障。     

学者学术影响力评价指标的优选与学术行为特点的国内外比较

以中国医学科学院73位从事临床科研的博士生导师为样本,分析不同学术年龄组在各学术影响力指标上的表现差异,并采用方差分析和相关性分析辅助优选指标。得到的优选指标包括发文量、总被引次数、篇均被引次数、h指数、A指数、g指数和累计影响因子,其中与“平均量”相关的篇均被引次数、A指数更适合于评价中国高水平学者的学术表现;而m熵指数不太适合于评价中国学者的国际影响力;中国科研人员的评价应该注意学术年龄这一因素。     

图书馆联盟中的机会主义行为风险及其防范研究

图书馆联盟是一个复杂的系统,协调各成员馆之间的利益差异和分歧,对合作中的机会主义行为进行有效的防范和控制,是保证联盟合作关系健康发展的关键。契约与信任机制在组建阶段可以对联盟可能出现的合作风险进行有效的预防,而监督与检查考核机制、激励与约束机制则贯穿于联盟的整个生命周期,在联盟的整个运行过程中规范和约束着成员馆的合作行为,从而消减和防范联盟的各种机会主义行为风险。
