The authors explore the results of the Comprehensive Business Exam (CBE) administered to business majors during their senior-year business capstone course. The study results identified students' SAT and grade point average as a predictor of CBE performance, and variables that explain the correlation between CBE performance, SAT score, and grade point average are discussed. This study expands the research stream by demonstrating how faculty can use CBE information to more deeply assess student learning at both the course and instructor level than is possible with the Major Field Test for Bachelor's Degree in Business.  相似文献

由于高度移植印度《合同法》,孟加拉《合同法》在效力方面的规定与大陆法系和英美法系合同立法原则有不少不同之处,尤其是对于要约和承诺的生效原则、未成年人签署合同的效力问题,均有实质差异。同时,对于条件合同和无效合同,孟加拉《合同法》虽然和我国一样秉承意思自治原则为主导,但对于所附条件的形式和实质内容以及合同无效之规定却颇有迥异。  相似文献

微波带状线低通滤波器的设计制作与性能改善   总被引:1,自引:0,他引:1  
讨论了带状线低通滤波器因实际制作的导带宽度发生变化引起滤波器性能下降时,如何改善滤波器性能的方法。我们采用惠普公司EESOF软件,对滤波器的结构和电气参数和分别作了灵敏度分析,以此为改善滤波器性能的依据。经实验对比,改进后的滤波器性能有了明显改善,且性能稳定。  相似文献

This study proposes and tests an integrative model to examine the relationships among customers’ willingness to share information, satisfaction, perceived value, and loyalty in a retailing context. This study extends research on customers’ willingness to share information from trust and privacy concerns toward key outcome measures such as perceived value, customer satisfaction, and loyalty, and is thus among the first to model customers’ willingness to share information with companies in robust theoretical retailing frameworks. The proposed relationships were tested using data from two retailing contexts – groceries (N = 429) and do-it-yourself (DIY) (N = 895). Findings from the two samples suggest that both perceived value and satisfaction are significant determinants of customers’ willingness to share information with a company. Although some differences emerge in the two studies, structural modeling largely supports the hypothesized framework and positions customers’ willingness to share information as an important antecedent of their loyalty intentions and behavior. This study provides practitioners with preliminary insight into the relationship between willingness to share information and perceived value, customer satisfaction, and customer loyalty. This study advances retailing research, as it is one of the few empirical studies investigating the role of customers’ willingness to share information in driving loyalty and its relationship with perceived value and satisfaction in a retailing context.  相似文献

The aim of this study is to investigate whether satisfaction with grocery stores is affected by type of grocery shopping in conjunction with time pressure, and which attributes are important for satisfaction. Fictitious grocery stores are constructed according to a fractional factorial design by varying access, price level, supply quality/range, and service quality. In an Internet survey, 1023 Swedish consumers rated satisfaction with major vs. fill-in shopping imagining they were under high or low time pressure. The results showed that satisfaction is higher for fill-in shopping than major shopping, that time pressure has no effect on satisfaction, and that price level, service quality, and product quality/range are more important for satisfaction with major shopping, whereas access is more important for satisfaction with fill-in shopping. It is also found that the importance of attributes for satisfaction depends on type of shopping more than on individual characteristics.  相似文献

宏观审慎监管需要微观基础.研究商业银行偿付能力风险与流动性风险和银行体系风险的关系,有助于监管当局制定合适的监管工具,有效管理银行业的系统性风险.中国未曾爆发过真正意义的银行业危机,因而研究影响银行业系统性风险的因素成为难题.在借鉴风险二维定义属性基础上,本文对商业银行偿付能力风险和流动性风险如何影响银行业稳定进行了实证分析.分析结果表明,当商业银行偿付能力上升时,银行风险承担会上升,进而增加银行倒闭的预期损失;商业银行流动性风险的上升也会增加银行倒闭的预期损失;商业银行偿付能力提高时,流动性风险会降低;商业银行流动性风险上升时,偿付能力风险也上升.  相似文献

This article constitutes a first attempt to systematically map the presence of women in the greatly changing Swedish advertising industry since 1930. The overarching aim of the study is to analyse how the gendered divisions of labour and business changed in relation to both business structure and the overall labour market in Sweden. While we conclude that women constituted around 40–50% of the workforce over time, we see an increase in the shares of women in higher positions and in women who were self-employed and managers. This upturn, however, stabilised during the 1990s. We argue that the changes in gendered divisions of labour and business coincided with a fast-changing business structure. First, the old cartel broke down in the mid-1960s. Then, the number of firms increased quickly during the 1970s and 1980s, and the market share for the largest firms declined. This, in turn, meant new business opportunities for women at the same time as their overall labour market participation increased. The article stresses the importance of both acknowledging women’s presence in the industry development as well as the structures constituting gender divisions.  相似文献

This paper reports a comparative qualitative study of how decision-makers in internationalizing SMEs respond to relevant institutions in their domestic environment through networking activity. Twenty SMEs are compared respectively from a developing economy (Egypt) and a developed economy (UK). The two countries contrast both in the effectiveness of their institutional support for SMEs and in their cultural norms towards network relationships. Substantial differences are found between the two national samples in SME decision makers’ networking behaviour in response to specific institutional conditions. The links between institutional conditions, national cultural norms and SME networking responses are explicated in a new theoretical model.  相似文献

Children’s daily consumption of food in childcare institutions has an impact on their public health nutritional status. The collaboration of parents and employees of kindergartens is important to ensure healthy eating habits among the next generation. Consequently, evaluations of lunch schemes are important to provide a good foundation for enhancing communication between home and institutional settings. The aim of this article is to assess parental satisfaction and identify themes related to parental perceptions of lunch schemes in Danish kindergartens. A survey was developed and distributed in four kindergartens with lunch schemes. A combination of closed and open questions were used to evaluate satisfaction and identify positive and negative aspects of the lunch schemes. Parents of 93 children participated in the study and the response rate was 55%. Eighty-nine percent expressed satisfaction with their children’s lunch scheme. According to parents, the most positive aspects were that lunch schemes serve a variety of food, their ability to prevent neophobia, that children learn that eating is a social occasion, and that the arrangements offer convenience to parents. The negative aspects identified were the lack of communication between the kindergarten childcare institutions and the parents regarding the food. Overall, parents are very satisfied with their children’s lunch schemes; however, the information between institutions and parents could be improved.  相似文献

Eating and exercising behaviour are both characterized by immediate and future consequences. Consequently, consideration of these consequences (i.e. time orientation) predicts eating and exercising behaviour. We investigate whether construal level acts as an underlying mechanism of these relations. Students (N = 101) completed measures of consideration of immediate and future consequences (i.e. CFC‐food and CFC‐exercise), construal level, eating and exercising behaviour and preferences. For self‐reported eating and exercising behaviour, only direct effects of consideration of immediate and future consequences were found. For eating preferences, however, there was evidence of an indirect effect through construal level. A stronger tendency to consider future consequences led to a stronger preference for utilitarian (as compared with hedonic) food products through a more abstract construal level. All in all, construal level partially explains the differential relations between consideration of immediate and future consequences and eating and exercising behaviour and preferences.  相似文献
