Dimensions of intercultural effectiveness: Culture specific or culture general?

Abe and Wiseman (1983) replicated Hammer, Gudykunst, and Wiseman's (1978) study of the dimensions of intercultural effectiveness. Subjects for the Hammer et al. study were Americans living in another culture for at least 3 months, whereas Abe and Wiseman's subjects were Japanese tourists in the United States. Three dimensions emerged in the original study and five in the replication. Abe and Wiseman interpret these differences as evidence for a culture-specific interpretation of intercultural effectiveness. The argument presented in this paper is that Abe and Wiseman's data do not support a culture-specific interpretation. Rather, it presents relatively unequivocal evidence for a culture-general interpretation. Differences in the two factor structures are explained in terms of sample size and length of stay.     

Education,health and care plans and tribunals in England: A statistical tale from 2019

Education, health and care (EHC) plans were introduced in England in 2014, as a replacement for statements of special educational needs. Unexpectedly, the number of children and young people in receipt of an EHC plan rose by 49% during the 5 years up to 2019. Whilst most of the increase has been due to the extension of the age range up to age 25, there has still been a notable rise of 20% in the 0–15-year range. This study explores the trends and variations in EHC plans and tribunals within English local authorities (LAs) for children and young people with special educational needs and disability (SEND) by interrogating the latest full set of data from 2013 to 2018. Two quintile groups (n = 30) are used for comparing LAs with high and low levels of EHC plans and LA case studies are also presented for further inspection of the data. Wide variations across LAs still exist for EHC plans (5.2% to 1.0%) and tribunal appeals (43 to 0 per 10,000). LAs with low EHC plans have more appealable decisions at tribunals and are financed at significantly lower levels than LAs with high EHC plans, largely due to an historic spend factor of 50% in the national funding formula. There are also clear differences between the English regions for both EHC plans and tribunals, with high increases for both in the South East. The implications of the findings are discussed within the framework of LA critical self-reviews, benchmarking, fiscal constraints and inclusion.     

高校女子篮球运动员人格与技术特点相关研究

运用艾森克人格问卷简式量表（EPQ—RSC）,对第十二届CUBA中国大学生篮球联赛女子八强队伍进行测查。结果表明：1）得分、三分球命中率、二分球命中率、失误与运动员艾森克N维度呈现显著性相关,罚球命中率、助攻与艾森克E维度呈现显著性相关,助攻、失误与艾森克P维度呈现显著性相关;2）粘液质、多血质球员在得分方面高于抑郁质与胆汁质,多血质与胆汁质球员三分球命中率、二分球命中率方面高于另外两种类型球员。结论：N维度低分运动员情绪较为稳定,是球队的核心人选,得分手以及二分球选手也都属于情绪稳定性;粘液质、多血质球员是球队的主要得分手,多血质与胆汁质球员是三分射手的优秀人选。     

Ka Pō, Ka Ao,Ka Awatea: The Interface between Epistemology and Māori Subject Headings

Cataloging and classification provide intellectual access for organizing resources in libraries. In New Zealand, bibliographic control is largely through the application of Library of Congress Subject Headings (LCSH). LCSH provide a sense of context and order. In Indigenous frameworks this sense of order can be found in the link between epistemology and knowledge structure. This article argues that the development and application of Māori subject headings is directly related to the natural order that is pivotal to a Māori worldview. The impact of this worldview and its associated values are explored in the context of the construction of Ngā ūpoko Tukutuku.     

Social Networks and Archival Context: From Project to Cooperative Archival Program

This article highlights the objectives and outcomes of the multi-year Social Networks and Archival Context (SNAC) research and demonstration project and discusses related developments to establish a large-scale sustainable cooperative for maintaining information about creators of archival collections, leveraging the Encoded Archival Context—Corporate Bodies, Persons, and Families (EAC-CPF) standard. The article discusses processes developed to derive EAC-CPF records from existing EAD finding aids, MARCXML records, and original authority records, enrichment of those records from other sources, and the creation of a prototype research resource, providing integrated access to dispersed archival collections and the social-historical context of the collections.
