Constraints to cruising across cultures and time

Cruise tourism is permeating the global arena. With companies developing new ships/itineraries for the U.S. and China markets, understanding constraints to cruising for different cultures carries significant value for cruise tourism development. This study adopted longitudinal and cross-cultural approaches to validate constraint measures. Data were collected in the U.S. in 2008 and 2017 and in China in 2017, using the same set of constraint measures across different times and cultures. This multi-dimensional triangulation approach was deemed important for testing the robustness of a measurement scale and is believed to be the first of its type. Findings validate the cruising constraint instrument across time and cultures and provide theoretical and practical implications.     

The Moderating Role of Strategic Integration in Performance Improvement Through Purchasing Social Responsibility in Thailand

This research aims to understand the performance of purchasing social responsibility (PSR) through moderating effect of purchasing strategic integration. The results show that PSR directly influences purchasing performance, while the relationship between PSR and purchasing performance is partially mediated by organizational learning. Moreover, strategic integration negatively moderates the relationship between PSR and purchasing performance. This study suggests that the adoption of PSR affects the operations of both buyers and suppliers in a supply chain that further encourage organizational learning and increases purchasing efficiency. The results also show that organizations may realize this effect of PSR practices but may focus on other purchasing practices, which affects purchasing performance. Copyright © 2018 ASAC.

Does corruption slow down innovation? Evidence from a cointegrated panel of U.S. states

I investigate the long-run relationship between corruption and innovative activity using annual data from 48 contiguous U.S. states between 1977 and 2006. Using U.S. data allows me to work with a panel long enough to exploit time series properties of the data. I use two different measures of innovative activity: one measuring the quantity and the other measuring the quality of the patents granted. I also use two different measures of corruption: one based on the number of corruption convictions, the other based on number of corruption stories covered in Associated Press news wires. Following Pedroni (1999, 2000), I estimate the cointegrating relationship between corruption and innovative activity with Fully Modified Ordinary Least Squares (FMOLS). The results indicate that corruption indeed slows down innovation in the long-run.     

Is it U.S. GAAP or IFRS? Understanding how R&D costs affect ratio analysis

While financial reporting standards under U.S. GAAP and IFRS are fundamentally similar, differences do exist that may affect our analysis of company financial statements. This is particularly true when comparing a U.S. company following U.S. GAAP to a firm that uses IFRS. To illustrate, we compare research and development (R&D) accounting methods under both sets of standards and illustrate how they affect the analysis of financial results of firms in a specific industry—automotive manufacturers. Our results provide insight into settings in which differences in R&D accounting may have the greatest impact on financial analysis.

Does data matter? Statewide longitudinal data systems and student performance in the U.S.

Although many industries have benefited from advances in data-driven technology, education is making small steps in capitalizing on the huge potential of data systems. Since 2005, the U.S. Federal Government has been making large grants to help states build statewide longitudinal data systems (SLDS) with the goal of improving programme and teacher evaluation and engage in data-driven decision-making. We analyse whether the introduction of SLDSs improved student performance, measured using test scores for math and reading tests for 4th and 8th graders, as well as high school graduation rates. We find no effects of SLDSs on student performance up to 10 years from implementation. However, we find suggestive evidence that these systems may have long-run effects, emphasizing the long-run nature of educational data collection and policy analysis.     

生产分工视角的中国对美国货物出口竞争力验证

考虑生产分工对中美间经贸联系程度、贸易规模和结构的影响,基于生产分工下价值链视角,构建出口竞争力测度指标体系,验证中国对美国货物出口竞争力。结果显示:2016年及之前,中国仅在杂项制品大类上,对美国显示出较强出口竞争力,机械和运输设备、动物和植物油、油脂和蜡我国具有比较优势,化学成品及有关产品、按原料分类的制成品双方竞争性较强,其余大类上,中国对美国出口竞争力不具优势。引入其他国家作对比的分析结果表明:中国对对比国家均无显著出口竞争力,而且对美国出口具有单价优势的资本技术密集型产品,对这些国家出口多缺乏单价优势,而2017年以来对美国和对比国家的贸易变化,进一步勾画出中国对美国货物出口竞争力不足。在生产分工主导全球产业发展背景下,提升我国在全球生产分工中的参与地位,宜强化自主技术研发、提升外资质量和技术外溢、加快"走出去"学习先进技术。     

共享型领导对员工建言行为的影响 ——员工权力感的中介作用

本文探讨了共享型领导对员工建言行为的影响,以及员工权力感的中介效应和差错风险承担、角色自我效能感的调节作用,丰富了员工建言行为、共享型领导的相关理论并给出了相应的实践建议。以上海多家企业中的员工以及其直属上级领导作为研究对象,通过194对领导-下属有效调查问卷分析得出了以下结论:①共享型领导对员工的促进性建言与抑制性建言都有显著的正向预测作用;②员工权力感在共享型领导与员工建言行为之间存在中介作用;③差错风险承担在员工权力感与促进性建言之间存在调节作用,角色自我效能感在员工权力感与抑制性建言之间存在调节作用。本文在此研究结果的基础上进行讨论并给出相关管理建议。
