Abstract

We examine how student attitudes toward their group, learning method, and perceived development of professional skills are initially shaped and subsequently evolve through multiple uses of team exams. Using a Tobit regression model to analyse a sequence of 10 team quizzes given in a graduate-level tax accounting course, we show that there is an anchoring effect, in that in later rounds satisfaction on all dimensions rests on the foundation laid in the initial round. Subsequently, however, self-perceptions and the perception of others may influence satisfaction on a particular dimension. We also find that the satisfaction with one's group tends to increase when students make more correct switches but decreases when there is greater disagreement among the group. Furthermore, satisfaction with team exams tends to lessen, and to an increasing extent over time, as the number of errors a student has committed on the most recent quiz increases.  相似文献

A typical detergent formulation for domestic garment washing is a complex formulation comprising: surfactants, builders, bleaches and auxiliary agents. Repeated exposure to surfactants can cause damage to the lipid film layer of the skin. Textile constructions used in clothing are also complex. Most apparel fabrics will be subject to a laundering process containing detergent at some time in the life cycle and thus it can be surmised that the combination of clothing and detergent is likely to be the cause of some skin problems. Certain fibre types show higher absorption rates than others. If surfactants present in domestic detergents are preferentially absorbed into the fabric during laundering and inadequately removed by rinsing a build‐up of the surfactant may exacerbate skin irritation. This paper offers a review of the debate on the effects of detergents on skin disorders plus recent research on clothing and detergents.  相似文献

Competitive pressures and market forces are augmenting the importance of product innovation as a source of competitive advantage. Key drivers underpinning market success have the capacity to develop the “right” products for the “right” customers, using the “right” channels, with a shorter development cycle than competitors. But when breakthrough products (BTPs) are involved, how do we sort out what is “right”? How do we identify customers' future requirements when the technology platforms are still unfolding, products are still in development and customers lack experience with the product? Traditional product development market research techniques are problematic since they assume the customer has historical experience with products similar to those being created. The objective of this paper is to raise the awareness of the OM community with the strengths and weaknesses of existing methodologies for developing and introducing innovative products to market. Further, it suggests promising future directions for both practice and research when BTPs are involved. This is important because of the central role OM plays in managing the success of the BTP development process.  相似文献

现在全世界的教育处在无声的紧急状况中——超过10亿的正处于应该接受基础教育年龄阶段的儿童失学了;15亿在上学的儿童在完成基础教育以前极有可能辍学;在非洲和南亚,只有不到1/3的儿童能够读和写。然而,尽管每天都有儿童死于艾滋病、营养不良以及其他一些只要他们的母亲完成过优质的基础教育就有可能被预防的疾病,但是CNN绝对不会捕捉到一个儿童因缺少教育而死亡这样的镜头。  相似文献

Food allergy is an increasing problem worldwide. Allergy to peanuts is a particular concern, given that this is rarely outgrown and may be associated with life‐threatening anaphylaxis. However, it is unclear what factors are responsible for a perceived increase in prevalence rates. One matter on which scientists agree, however, is that exposure to peanuts early in life is significant – although whether early exposure protects or sensitizes to allergy is unclear. There is no significant research that currently records differences in early life exposure either within or between populations. This exploratory study makes a first step in this direction using focus groups conducted in four countries with disparate ‘peanut experiences’ to characterize early exposure in these. The ultimate aim is to help in the development of a survey instrument to attain nationally representative samples of consumers and hence to use the results from this to compare with allergy prevalence data collected in other parts of the European Union‐funded ‘EuroPrevall’ project. The results in this study not only reveal considerable similarities across countries (e.g. in terms of lack of knowledge of guidelines; lack of changes in feeding behaviour during/after pregnancy, feelings that diet variety in children is important) but also one or two interesting and potentially important differences, such as increased consumption in Bulgarian (and some Spanish) breastfeeding mothers because of the ability of peanuts to facilitate lactation. Study limitations and future study intentions are also discussed.  相似文献
