Estimation of parameters in DNA mixture analysis

In [7], a Bayesian network for analysis of mixed traces of DNA was presented using gamma distributions for modelling peak sizes in the electropherogram. It was demonstrated that the analysis was sensitive to the choice of a variance factor and hence this should be adapted to any new trace analysed. In this paper, we discuss how the variance parameter can be estimated by maximum likelihood to achieve this. The unknown proportions of DNA from each contributor can similarly be estimated by maximum likelihood jointly with the variance parameter. Furthermore, we discuss how to incorporate prior knowledge about the parameters in a Bayesian analysis. The proposed estimation methods are illustrated through a few examples of applications for calculating evidential value in casework and for mixture deconvolution.     

教师应具备的教育实验素养

改革开放以来,我国的教改实验蓬勃发展,成效显著,但同时也存在着一些制约实验健康发展的关键性问题,如缺乏对实验规范及方法的了解,实验的价值取向不明,问题意识不强等。而这些恰恰是从事教育实验的教师必须具备的基本素养。从相关问题入手,分析教师的基本实验素养,对促进我国教育实验的健康发展具有重要意义。     

基于NVivo质性分析的羌族灾后心理复原力的影响因素研究

采用NVivo10.0软件分析灾后羌族幸存者心理复原的现状和影响因素,为少数民族受灾群体心理干预提供依据。以5.12地震羌族重灾区茂县、理县为例,采用目的性抽样方法,对12名羌族幸存者进行个案访谈,收集他们对地震的认知、反应和应对方式,以及影响其灾后心理复原的因素,探索建立灾后心理复原力的影响因素模型。羌族幸存者对地震情境、受灾情况仍记忆犹新,心存恐惧,地震带来的创伤或将长期存在;灾后国家政府的支援扶持、民族文化元素成为应对灾难的支持性力量和保护性因子;心理复原力影响灾后羌族幸存者的主观幸福感体验。应重视积极文化元素对羌族心理复原的保护和支持作用,可尝试将民族文化元素引入灾后心理治疗与干预。     

普通高校研究生政治效能感实证研究

政治效能感是一种个人认为自己的政治行动, 会对政治过程产生政治影响力的感觉, 也是值得个人去实践其公民责任的感觉. 对1 000名研究生的政治效能感的实证研究调查结果显示, 影响内部政治效能感的因素主要有政府级别、政治兴趣和政治知识掌握度, 而影响外部政治效能感的因素主要有民主决策活动的参与度、 学习和讨论政治议题以及对政治团体的认同感. 基于上述因素, 提出应当重视培养研究生对公共事务关注的兴趣, 以及多渠道、 多途径、 全方位地增强研究生的政治效能感.     

Sampling Richness and Qualitative Integrity: Challenges for Research With Families

Sampling is one of the most difficult and contentious aspects of qualitative research design. There are few guidelines for sampling decisions or for understanding saturation in qualitative family research. The authors frame the problematic of data quality in the selection of units of analysis and observation and consider how to enhance sample richness. They outline considerations for data quantity and sample size as well as case‐ and variable‐based approaches. With multiple examples from recent and classic studies to illustrate the consequences of sampling decisions, they explore links between saturation and validity. Finally, they encourage researchers to craft a coherent statement on qualitative integrity to demonstrate how their sampling decisions are rooted in epistemology, theory, and richness and quality of data.     

Unless you go online you are on your own: blogging as a bridge in para-sport

Since its inception, the Web has been described as a liberating technology permitting individuals with disabilities to surmount barriers that otherwise prevent full societal engagement. Subsequent studies of Web-based communication have instead reported that disabling conditions are reproduced rather than challenged online. This paper uses interviews with 25 para-sport participants to provide an empirical account of how the affordances of the Web are leveraged in disability sport networks. Our findings suggest that individuals with disabilities are using blogs, Facebook, Twitter, and other forms of online communication to find information, engage in advocacy and outreach projects, and form strong networks that extend online and offline. We discuss our findings in light of Putnam’s conceptualization of bridging and bonding social capital, and describe how individuals and groups use weak ties to disseminate information and strong ties to foster a sense of belonging.     

Responsibility in Home–School Relations — Finnish Parents' Views

Finnish parents' views on responsibility in the home–school relations were explored. Responsibility was here understood as responsibility over education and upbringing. The data consist of semi‐structured interviews with 24 mothers and four fathers. In the home–school discourses, parents and teachers were often referred to as partners, and active parental involvement in school life was seen as a key to children's success. However, in some discourses teachers and parents were seen as polar opposites, e.g. teachers as experts — parents as laymen. Few references were made to children's responsibility.     

Translation Strategy for Animal Images from Cultural Perspectives

动物是人类生活中必不可少的一部分.人类语言有许多跟动物有关系.事实上,动物形象在语言中隐含的深层次意思绝不是动物本身所反映出来的意义.由于东西方国家在历史、文化和生活环境方面的差异,动物背后隐含着的文化意义并不都是一致的.对于译者而言,在翻译有关动物形象的语言时,采用恰当的翻译方法、考虑动物形象背后隐藏着的文化内涵是很有必要的.     

Research Based Recommendations for Child Custody Evaluation Practices and Policies in Cases of Intimate Partner Violence

This article reviews recent research on child custody evaluations in intimate partner violence (IPV) cases. Specifically, it covers assessment methods, evaluator selection, evaluator education, guidelines, differential assessment, and state policies. Special attention is given to new methods of bias reduction, the need to focus on coercive and controlling abuse, and the need to interpret psychological tests within a trauma framework. Recommendations are made in each area reviewed.
