Relinking Cross‐functional Collaboration,Knowledge Integration Mechanisms,and Product Innovation Performance: a Moderated Mediation Model

Previous research shows that knowledge integration mechanisms (KIMs) mediate the cross‐functional collaboration‐product innovation performance relationship; however, this mediating effect seems to be rather weak. This study, in contrast, develops a moderated mediation (MOME) model to argue that such a mediating effect is moderated by product innovativeness. A sample comprised of 106 manufacturing firms is utilized in the analyses. A moderated‐mediation approach shows that the mediating effect of KIMs in the linkage between cross‐functional collaboration and product innovation performance varies by different perspectives of product innovativeness. From an industry (macro‐level) perspective, product innovativeness positively moderates the mediating effect of KIMs on product innovation performance; in contrast, such a moderating effect is not significant under a firm (micro‐level) perspective.

基于TANG模型的西安国际旅游成长实证分析

文章运用旅游地非线性成长模型（TANG模型）对50年来西安国际旅游成长进行实证分析。分析指出，西安国际旅游第一周期为新中国成立至改革开放前阶段，规模极小，受政府制度、资源与产品创新、大规模突发事件影响极大；从客流量与旅游收入两个指标体系入手，讨论1978年以来的第二、第三周期，通过模拟方程、成长曲线及相关特征值实现了不同周期、不同指标的横向与纵向比较，同时在与统计值进行对比的过程中，清晰地反映出异常波动情况，判断波动原因，对旅游地成长过程有了更为清晰的认识。     

Further Evidence on Insider Selling Prior to Seasoned Equity Offering Announcements: The Role of Growth Opportunities

Previous research documents significant abnormal net selling by insiders prior to seasoned equity offering announcements. This study documents that the abnormal net selling is significantly greater for growth firms than for mature firms. It also shows that growth firms experience poorer post-issue long-term price performance, which suggests greater overpricing for growth firms. Further analysis shows that greater insider selling prior to the offering announcement is associated with a greater price run-up prior to the announcement and is not associated with a more negative market reaction to the announcement. Overall, the results suggest that investors may be overly optimistic about future prospects of growth firms.

The effects of understanding rules and a worked example on the acquisition of procedural knowledge and task performance

Previous research (for example, Bonner and Walker, 1994) has investigated the impact of alternative forms of instruction and practice on both the acquisition of procedural knowledge and task performance. Responding to the call to consider alternative forms of instruction, this study reports the results of an experiment designed to distinguish between the effects of understanding rules and a worked example. Worked examples (such as previously prepared working papers, analysis sheets and spreadsheet templates) are of particular interest as they constitute an important source, frequently used by novice accountants, for understanding and performing various tasks.
The results indicate that understanding rules increase task performance through the acquisition of procedural knowledge, while a worked example provides task-specific heuristics that increase task performance but not procedural knowledge. The different benefits of the two forms of instruction emphasise the importance of matching instruction methods to learning objectives. Furthermore, combining the two forms of instruction lead to the highest levels of task performance even with limited practice and no feedback.

Does China＇s Huge External Surplus Imply an Undervalued Renminbi？

A pegged exchange rate regime has been pivotal to China's export-led development strategy. However, its huge trade surpluses and massive build up of international reserves have been matched by large deficits for major trading partners, creating acute policy concerns abroad, especially in the USA. This paper provides a straightforward conceptual framework for interpreting the effect of China's exchange rate policy on its own trade balance and that of trading partners in the context of discrepant economic growth rates. It shows how pegging the exchange rate when output is outstripping expenditure induces China's trade surpluses and counterpart deficits for its trading partners. An important corollary is that given its strictly regulated capital account, China's persistently large surpluses imply a significantly undervalued renminbi, which should gradually become more flexible.

Gender differences in knowledge and attitude regarding breastfeeding

The literature presented evidence that the opinions and attitudes of the father or male partner towards breastfeeding have a strong positive correlation with breastfeeding initiation and duration. Men are also found less knowledgeable about breastfeeding and are more positive towards formula feeding than women. Using a survey of college‐aged men and women, this study provides in‐depth understanding of gender differences in knowledge and attitude regarding breastfeeding. The Infant Feeding Knowledge Test and the Iowa Infant Feeding Attitude Scale were included in the questionnaire in addition to questions about the respondents' intention to breastfeed, exposure to breastfeeding during infancy and socio‐demographic characteristics of the family of origin. The final sample consists of 181 women and 88 men enrolled in a university in the Southern US. Linear regressions with gender interaction terms were estimated in order to isolate the gender‐specific correlations between their family background and their knowledge and attitude regarding breastfeeding. A series of Chi‐square tests examined whether the regression coefficients were significantly different between men and women. Results support existing evidence of gender gap in breastfeeding knowledge and attitude. More importantly, the study reveals that the influence of one's family background on their knowledge and attitude regarding breastfeeding is significantly different between men and women. It suggests a possibility of greater disagreement regarding feeding choices within a higher socioeconomic status (SES) couple. Theoretical and practical implications of the findings are discussed.     

Efficiency change and growth in productivity: the Asian growth experience

This paper focuses on identifying the sources of productivity growth in ten Asian economies including China, Japan, the NIEs and the ASEAN-4. We calculate productivity growth and its components using distance-function-based Malmquist productivity indexes following Färe, Grosskopf, Norris, and Zhang (1994a). Hong Kong and Singapore are found to have the capabilities to shift the grand frontier of the APEC economies. But the productivity divergence might have occurred since the 70’s. The FDI contributes to the Asian growth either through catching-up or through technological innovations when a sufficient learning capacity is available in the host economy.
