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.  相似文献

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.  相似文献

Objective: Airway inflammation and airway hyper-responsiveness (AHR) are principle pathological manifestations of asthma. Cluster of differentiation 69 (CD69) is a well-known co-stimulatory factor associated with the activation, proliferation as well as apoptosis of immune cells. This study aims to examine the effect of anti-CD69 monoclonal antibody (mAb) on the pathophysiology of a mouse model of asthma. Methods: A murine model of ovalbumin (OVA)-induced allergic airway inflammation was used in this study. Briefly, mice were injected with 20 μg chicken OVA intraperitoneally on Days 0 and 14, followed by aerosol provocation with 1% (0.01 g/ml) OVA on Days 24, 25, and 26. Anti-CD69 mAb or isotype IgG was injected intraperitoneally after OVA challenge; dexamethasone (DXM) was administrated either before or after OVA challenge. AHR, mucus production, and eosinophil infiltration in the peribronchial area were examined. The levels of granulocyte-macrophage colony-stimulating factor (GM-CSF) and interleukin-5 (IL-5) in bronchoalveolar lavage fluid (BALF) were also assayed as indices of airway inflammation on Day 28 following OVA injection. Results: Pretreatment with DXM together with anti-CD69 mAb treatment after OVA provocation completely inhibited AHR, eosinophil infiltration and mucus overproduction, and significantly reduced BALF IL-5. However, treatment with DXM alone after OVA challenge only partially inhibited AHR, eosinophil infiltration and mucus overproduction, and did not diminish BALF IL-5. Treatment with either DXM or anti-CD69 mAb did not alter the concentration of BALF GM-CSF. Conclusions: Anti-CD69 mAb treatment inhibits established airway inflammation as effectively as DXM pretreatment. This study provides a potential alternative therapeutic opportunity for the clinical management of asthma and its exacerbation.  相似文献
