‘Inclusion in Practice’: Programme Practices in Mainstream Preschool Classrooms and Associations with Context and Teacher Characteristics

This study observed the extent to which teachers supported the inclusion of children with disabilities into mainstream classrooms and involved monitoring 52 mainstream preschool settings in Greece. The association between programme quality, context and teacher characteristics was also tested. Findings showed that the quality of inclusion ranged from ‘low’ to ‘minimal’, with teachers more frequently implementing practices that only partially promoted participation for children with disabilities in academic and social classroom activities. The analysis also revealed that the quality of programming was not influenced by the model of special education provision, the group size, the number of children with disabilities, the training teachers had in special education or their teaching experience. The results are discussed both at a national and international level, revealing areas that need further examination into preschool inclusion quality.     

文化记忆资源的知识融通:从异构资源元数据应用纲要到一体化本体设计

[目的/意义]探索美术馆、图书馆、档案馆、博物馆等机构(GLAM)中多源异构文化记忆资源跨领域跨机构的知识融通解决方法和路径。[研究设计/方法]在“元数据应用纲要”的基础上,提出了“本体应用纲要”的概念,以上海图书馆手稿档案元数据应用纲要扩展为本体应用纲要为例,阐述了本体应用纲要设计的原则、方法和流程;以历史人文“数据基础设施”进一步构建了一体化本体及其知识融通模型,并验证基于本体应用纲要在一体化本体框架下的扩展以实现跨领域知识融通的方法。[结论/发现]元数据应用纲要为文化记忆资源的知识融通提供了结构化数据储备,本体应用纲要兼顾了特定资源类型的个性化需求,一体化本体的知识融通模型则用于保证知识建模的统一性和知识表示的一致性。[创新/价值]基于多种本体应用纲要的一体化本体设计方法和关联数据与知识图谱技术结合后,作为一种新的知识组织方法,为跨机构跨领域的知识融通提供了方法和路径。     

Profiles of Multi-cultural Identity Integration in a Conflictual Context

This study addressed the phenomenon of multiple social identities in a conflictual context. It examined the case of Palestinian-Christians living in Israel, a nation imbued with ethno-religious conflict, a complex combination of three distinct collective identities: national (Palestinian-Arab), ethno-religious (Christian), and civic (Israeli). The current study proposed a conceptual and methodological expansion of the “Bicultural Identity Integration” (BII) model (Benet-Martinez & Haritatos, 2005) as a way to assess different levels of integration between three types of identities (national, ethno-religious, and civic) in a sample of 383 Palestinian Christians with Israeli citizenship. Results revealed that the three integrations of BII (Arab-Christian, Arab-Israeli, Christian-Israeli) are positively predicted by favorable intergroup contact with Jews and Muslims and negatively by discrimination by these groups. Further, Latent Profile Analyses revealed four distinct identity profiles: two (“Pro-Arab” and “Pro-Israel”) were highly conflictual and characterized by both discrimination and negative intergroup contact, and two (“Ambivalent” and “Peaceful”) were characterized by less conflict across pairs of identities. These findings are discussed in terms of their theoretical contribution to the study of multiple social and collective identities in contexts of conflict, and their practical implications for the groups under study.

Energetic demand and physical conditioning of table tennis players. A study review

Table tennis is a racket sport characterised by an intermittent movement profile, including short rallies interspersed with short breaks. In contrast to other racket sports, information is lacking regarding the: (i) physiological responses during table tennis matches and training; and (ii) practical recommendations for enhancing aerobic and anaerobic performance in table tennis by improving cardio-metabolic and neuro-muscular fitness, anthropometry and nutritional strategies. Therefore, this review article attempts to narratively provide an overview of the physiology of table tennis by describing the metabolic mechanisms underlying match play and outlining a framework for practical recommendations for improving cardio-metabolic and neuro-muscular fitness, anthropometry as well as nutritional strategies. A second aim was to stimulate future research on table tennis and to point out study limitations in this context. In general, the most important finding is that the rally duration is short at around 3.5s, with a longer rest time of around 8–20s, resulting in an effort-rest ratio ranging from 0.15 to 0.22 in official matches and energetic demands during match relatively low. Future studies should focus on the relationship between energetic demand and table tennis performance with a view to predicting performance in table tennis using physiological parameters.     

蚌埠地区设施土壤盐分累积特征研究

对蚌埠市怀远和固镇两地不同年限设施土壤的盐分累积特征进行了研究,测定了土壤剖面各层次中的盐分总量和Na+、K+、NH4+、Ca2+、Mg2+、NO3-、H2PO4-、Cl-、SO42-、HCO3-等10种离子的含量,根据这10种离子之和与盐分总量的比值计算"盐分回收率".结果表明,大棚内土壤表层的盐分总量是露地土壤相同层次的2.4～5.7倍,盐分主要聚积在0～15cm土层中,尤其是0～5cm层次中;随着大棚使用年限的延长,盐分总量有增加趋势;除Na+和HCO3-外,NH4+、Ca2+、Mg2+、NO3-、H2PO4-、SO42-在大棚表层土壤中都有明显的累积,尤以Ca2+和NO3-累积严重,怀远大棚表层土壤的Ca2+和NO3-占盐分离子总量的63.8%,固镇大棚表层土壤的K+、Ca2+和NO3-占盐分离子总量的73.3%;根据"盐分回收率"推断,除了本文测定的10种离子外,还有相当数量(约占总盐的15%～23%)的其他重金属离子和非金属离子存在于大棚土壤中.     

Utilising the Boxall Profile within the Scallywags service for children with emotional and behavioural difficulties

In this article, Moira Broadhead, Roy Chilton and Victoria Stephens offer an in‐depth analysis of a targeted intervention, Scallywags, aimed at children with emotional and behavioural difficulties. Scallywags, based in Cornwall, offers an early intervention package for children and their families based upon an initial Boxall Profile analysis. Moira Broadhead is a senior educational psychologist for the Scallywags service and both Roy Chilton and Victoria Stephens held split posts as assistant psychologists and support workers within the intervention service. Moira, Roy and Victoria offer practitioners new to the Boxall Profile a compelling account of how it can be used to inform practice for learners with emotional and/or behavioural difficulties and conclude with a series of insightful questions about the use of the Boxall Profile and the role of interventions of this nature.
