Our research is a response to the need to improve the understanding of the complexity of global professional communication. To investigate the complex cultural interpretations that producers and audiences apply to professional texts, we developed a two-year interactive project. Business students in New Zealand and Israel produced promotional “texts” – video clips to promote a university program – which they exchanged with their counterparts overseas to receive feedback. We adapted models of home-made visual communication and advertising which used the categories of participants, settings, topics, and style, to analyze the eight clips. Emergent findings suggested two more categories – information and language – as important analytical tools. Variables of age, gender, intra- and intercultural differences, and (cultural) context also resulted in student audiences’ multiple interpretations of the texts. The outcomes indicate the need to extend the culture-in-context approach for a “situation focused communication approach,” where the primary focus is a group of producers and their audience as they produce and interpret a professional text. This approach also foregrounds contextual variables and a plural understanding of culture to accommodate the potential for miscommunication of business and professional texts in pluricultural contexts.  相似文献

There have been many conflicting observations between the linear or curvilinear decline in maximal heart rate (HRmax) with age. The aim of this study was to determine if linear or curvilinear equations would better describe the decline in HRmax with age in individuals of differing cardiorespiratory fitness (CRF) levels. Treadmill cardiopulmonary exercise test (CPX) results from participants (1510 men and 1134 women; 18–76 years) free of overt cardiovascular disease were retrospectively examined using cross-sectional and longitudinal study designs. Participants completing ≥2 CPX with ≥1 year between test dates were included in the longitudinal analysis (325 men and 150 women). Linear and quadratic regressions were applied to age and HRmax for the whole cohort and respective CRF groups (high, moderate, and low, relative to age and gender normative values). To test for differences among linear, quadratic, and polynomial equations, the change in R2 (cross-sectional analysis) and Bayesian information criterion (BIC) (longitudinal analysis) from the linear to the more complex models were calculated. The quadratic or polynomial regression in the cross-sectional analysis, marginally improved the variance in HRmax explained by age compared to the linear regression for the whole cohort (0.2%), moderate fit group (0.3%), and low fit group (0.8%). With no improvements in the high fit group. BIC did not improve for any CRF category in the longitudinal analysis. In conclusion, the minimal differences among linear, quadratic, and polynomial equations in the respective CRF groups, emphasizes the use of linear prediction equations to estimate HRmax.  相似文献

The purpose of this study is to examine how parental drinking behavior, drinking locations, alcohol outlet density, and types of social support (tangible, emotional, and social companionship) may place children at greater risk for physical abuse. Data on use of physical abuse, drinking behaviors, types of social support, social networks, and demographic information were collected via telephone interviews with 3,023 parent respondents in 50 cities in California. Data on alcohol outlet density were obtained by the California Department of Alcoholic Beverage Control. Multilevel Poisson models were used to analyze data for the drinking levels in the entire sample and dose-response drinking models for drinkers. Social companionship support was related to more frequent use of physical abuse. Having a higher percentage of social companionship support network living within the neighborhood was related to more frequent physical abuse in the full sample. This relationship was moderated by on-premise alcohol outlet density. With regards to drinking behaviors, drinking behaviors from ex-drinkers to frequent heavy drinkers used physically abusive parenting practices more often than lifetime abstainers. The dose-response models show that each additional drinking event at a bar or home/party was related to more frequent use of physical abuse. Practitioners working with parents who abuse their children should be aware that not all social support is beneficial. Findings build evidence that child maltreatment is influenced by the interaction between individual and ecological factors.  相似文献

Although sabbatical leave for teachers was suggested in the James Report more than 25 years ago, it remains as much of an unattainable ideal as ever—a sad fact in the light of the message of this paper. What Les Summers tells us clearly illustrates the potential value that sabbaticals might have for teachers: how they might return to school both refreshed and with new and innovatory ideas. The chance to study some schools in Australia enabled Summers to do just this, and he was able to see issues of disaffection here from a new perspective as a result of his experiences. He then went on to develop the idea of a programme which responds to the needs of young school leavers.  相似文献

Current data suggest fewer females than males continue to be interested in engineering and that this gender gap is first evidenced during middle school years. One might expect that female engineering role models would encourage adolescent girls to pursue future careers in engineering and thereby increase the girls’ interests in and attitudes towards science and mathematics. This study sought to correlate middle school girls’ overall confidence in science and mathematics with a year-long, afterschool mentoring program led by female engineering students from a local university. The results demonstrated that there was a significant correlation between the quality of the mentoring relationship and the girls’ confidence in mathematics. The relationship between female role models and young girls’ attitudes toward science and mathematics is discussed.  相似文献
