X荧光光谱法快速测定糙米中的镉

采用重金属镉富集装置对被测糙米进行先碳化后灰化的处理,使得被测糙米中的镉元素富集;将得到的被测糙米灰分放入样品杯中压制成被测样品,由X射线荧光分析装置进行测量,得到镉元素的信号强度,然后根据信号强度与浓度的比例关系自动计算样品中镉的含量.整个分析过程在15 mim以内,数据结果与AAS结果一致。

Exchange and refund of complementary products

A common dilemma a consumer faces during product return pertains to the decision of exchanging the product or obtaining a refund. This issue becomes even more salient for durable goods, when the initial purchase involves complementary products from different categories. This research examines consumer’s trade-off decision between returning and keeping complementary products by exploring various retail actions (using umbrella branded products (UBP)) and customer characteristics. We also investigate the trade-off between product exchange and refund when consumer returns a product. We find interesting extensions to past research wherein UBP are returned less and result in greater exchange than refund. Furthermore, an interesting caveat is that higher degree of complementarity between UBP intensifies the impact of various factors on exchange as opposed to refund of products. Implications for retail managers and sales teams are explored.     

Guanxi,political connections and resource acquisition in Chinese publicly listed private sector firms

In this study, we examined the role of guanxi as entrepreneurs’ resource-obtaining mechanism in private sector firms, using a data-set of 184 publicly listed firms in China. We found that guanxi indeed played a positive role that helped private sector firms gain easier access to resources. We also found that guanxi exerted even a greater positive effect on private sector firms’ resource obtaining compared to entrepreneurs’ political participation, due to being the lifeblood of business conduct and social interaction in Chinese culture.     

Drivers of customer decision to visit an environmentally responsible museum: merging the theory of planned behavior and norm activation theory

The main goal of this research was to merge the theory of planned behavior and the norm activation theory into one model and test its applicability in an environmentally responsible museum context. A filed survey was conducted at museums. Structural equation modeling was used to test research hypotheses. Results of the structural model comparisons revealed that the prediction power of our integrated model was superior to that of the theory of planned behavior and the norm activation theory. The proposed relationships among research constructs were generally supported. The mediating role of study variables was established. Additionally, the salient role of personal norm and attitude in generating museum travelers’ pro-environmental intention was identified. Overall, there was a strong support for the proposed theoretical model.     

Emerging youth tourism: fostering young travelers’ conservation intentions

Greening is one of the most important issues faced by the tourism industry today. Nevertheless, theoretical and empirical research on young travelers’ sustainable behaviors is scarce. This study developed a conceptual framework involving biospheric value, environmental concern, environmental awareness, ascribed responsibility, and moral norm in order to better explain young travelers’ pro-environmental decision-making process. A total of seven hypotheses were proposed and tested using structural equation modeling. Results revealed that the postulated theoretical model satisfactorily accounted for three dimensions of young tourists’ environmentally responsible intentions; the study variables are all significantly related; and the mediating impact of moral norm and environmental concern was evident. Moreover, the prominent role of moral norm in forming intentions was noteworthy. Our findings from the invariance test further indicated that environmental awareness and ascribed responsibility acted as moderators. The implications of these results are discussed.     

Cognitive,affective, conative,and action loyalty: Testing the impact of inertia

Research increasingly emphasizes the significance of customer loyalty to a firm's success. In order to provide a clearer understanding of hotel customers’ loyalty-formation process, this study proposed and tested an extended Oliver's (1997) four-stage loyalty model by employing a multi-dimensional approach for each attitudinal loyalty stage while considering the moderating impact of inertia. The original model was slightly altered to improve its fit and predictive ability. Results from the structural model generally supported proposed paths among the variables in the model (cognitive, affective, and conative loyalty components and action loyalty) and verified the mediating roles of study variables in forming action loyalty. Further, findings from structural group comparisons using invariance tests indicated that the links from satisfaction to commitment and intention and from intention to action loyalty were stronger for the low inertia group, supporting the moderating role of inertia. Implications are discussed, and limitations of this study are briefly outlined.

欧盟竞争法豁免制度及对我国的启示

竞争法豁免制度可以平衡竞争政策与经济政策、社会政策之间的冲突,有助于实现竞争法的多重价值目标。以基础性条约、欧盟理事会的条例、欧洲委员会的通知、指导建议及欧洲法院判例为渊源,以个案豁免和类别豁免为内容,欧盟的竞争法已建立起完备的豁免制度。我国反垄断法豁免制度的构建既要借鉴"他山之石"又要立足于"本土资源"。在制度设计上至少应思考并解决三个问题:豁免制度具体应包含哪些类型的豁免?豁免制度的适用采用审查确认制度还是直接适用制度?豁免制度立法采具体列举式还是原则概括式?     

外来务工人员就业流动性的影响因素分析——基于广州市外来务工人员的抽样调查

在我国城市化飞速发展的今天,外来务工人员在城市中就业岗位的不断流动已成为普遍现象。文章基于广州市这个珠三角典型城市的抽样调查,通过构建probit量模型,探求城市外来务工人员就业决策的影响因素,重,董分析个人因素、社会因素和企业因素等对外来务工人员就业偏好的具体影响。建议政府部门针对外来务工者的就业特征,制定促进就业的相应政策;而企业也应根据这种偏好,制定和完善相应的人力资源战略举措,促进企业持续健康发展。
