National culture and R&D and marketing integration mechanisms in new product development: A cross-cultural study between Singapore and New Zealand

The integration of R&D and marketing in new product development (NPD) is an important contributor to NPD performance. Of the mechanisms developed to aid functional integration, many have been developed in western cultural environments and may not have applicability in other national cultural settings. Using a sample of NPD workgroup personnel in New Zealand (NZ), the western cultural environment, and Singapore, quantitative and qualitative data have been used to measure national culture and determine the applicability of different organization integration mechanisms. Results show key differences between the two samples, indicating a link between formalization, centralization, role flexibility and interfunctional climate mechanisms with the Hofstede dimensions of Power Distance, Masculinity and Uncertainty Avoidance of national culture. Managerial implications are that national cultural values and settings of the respondents are important when determining best integration mechanisms.     

A Rich Vein for “Reality Mining”北大核心CSSCISSCI

Arik Hesseldahl In the aftermath of the September 11 attacks, U.S. officials quickly turned their attention to other potential targets, including California's Golden Gate Bridge. What would happen if terrorists took down the bridge between San Francisco and Marin County? How much of the region would be affected and for how long?     

产品市场势力能降低股票市场的异质信念吗——基于A股市场的实证研究

基于2001年至2009年A股市场的数据,本文检验了Peress(2010)提出的产品市场势力降低股票市场异质信念水平的推断,并分析了Miller(1977)提出的影响股票市场异质信念的因素。我们发现产品市场势力不仅不能降低反而可能会提高股票市场异质信念的水平。在将异质信念分解为异质先验导致的异质信念,渐进信息流动、有限注意导致的异质信念后,这种提高主要表现在对后者的提高上。该结果意味着产品市场势力可能因为提高了异质信念水平而促进了股票市场的交易,从而为交易异象的解释提供了新的思路。此外,实证结果显示上市公司的业务集中度、机构持股可以降低异质信念水平,而上市公司的已上市时间、市场中股票数量对于异质信念的影响与已有的理论分析并不完全一致。     

Compulsory versus voluntary voting: An experimental study

We report on an experiment comparing compulsory and voluntary voting institutions in a voting game with common preferences. Rational choice theory predicts sharp differences in voter behavior between these two institutions. If voting is compulsory, then voters may find it rational to vote insincerely, i.e., against their private information. If voting is voluntary so that abstention is allowed, then sincere voting in accordance with a voter's private information is always rational while participation may become strategic. We find strong support for these theoretical predictions in our experimental data. Moreover, voters adapt their decisions to the voting institution in place in such a way as to make the group decision accuracy differences between the two voting institutions negligible. The latter finding may serve to rationalize the co-existence of compulsory and voluntary voting institutions in nature.     

Neighbourhood Effects as Indirect Effects: Evidence from a Dutch Case Study on the Significance of Neighbourhood for Employment Trajectories

One of the key challenges in the study of neighbourhood effects on work is to understand the pathways through which disadvantaged neighbourhoods impact the employment opportunities of residents. Endogenous explanations for neighbourhood effects focus on social life in these neighbourhoods, identifying mechanisms of social isolation, deviant work ethics and neighbourhood disorder. This article studies these mechanisms in a low‐income neighbourhood in the Netherlands. The case study shows that unfavourable socioeconomic outcomes can be indirect and unintended consequences of actions and choices in everyday life that are not directly concerned with work. Nevertheless, these individual actions and choices reflect local social practices that are influenced by the marginalized context in which residents lead their lives.     

因材施教——声乐教学的重要法则

声乐与其它的艺术形式存在着明显的区别，由于难以形象地对声乐的乐理、思想等进行表达，因此在声乐教学的过程中如何有效地让学生更好地理解声乐知识，更好地掌握发声技巧等一直是广大声乐教师关注的重点。鉴于此，文章主要就声乐教学中的因材施教进行研究，通过努力在声乐教学中推动因材施教，学生才能对此会产生更浓厚的兴趣，更好地用声乐来表达内心的思想与情感。

Non-revelation mechanisms in many-to-one markets

In this study we present a simple mechanism in a many-to-one matching market where multiple costless applications are allowed. The mechanism is based on the principles of eligibility and priority and it implements the set of stable matchings in Subgame Perfect Nash Equilibrium. We extend the analysis to a symmetric mechanism where colleges and students interchange their roles. This mechanism also implements the set of stable matchings.     

Vision (im)possible? The effects of in-store signage on customers’ visual attention

We used two eye-tracking field experiments to investigate the extent to which in-store signage is used during navigation and decision making, and how the viewing of signage influences customers’ visual attention and choice behavior. One hundred and seventy-five customers at a grocery store were exposed to signage stimuli while carrying out predefined shopping tasks. Experiment 1 shows that attention toward signage is affected by customers’ levels of store familiarity and in-store search stage (navigation vs. decision making). Experiment 2 demonstrates that signage has a considerable impact on the direction and magnitude of customers’ visual attention during decision making.
