Threats to the Validity of Logistics and Supply Chain Management Research

To increase the relevance of logistics and supply chain academic research, this paper recommends the development and testing of middle‐range theory and practice‐level theory. Yet, there are a number of research issues that arise when academic researchers test middle‐range and practice‐level theory, both in measuring constructs and in testing theoretical relationships between constructs. Concerning the measurement of constructs, this paper recommends that academic researchers pay more attention to content validity and undertake rigorous processes to ensure content validity. In addition, academic researchers need to more explicitly define constructs as either reflective or formative. If the construct is defined as formative, then the traditional statistical approaches to validate these measurement scales are not recommended. The appropriate use of employing single‐item measures for concrete constructs is discussed. In regard to conducting hypothesis tests, research issues associated with multicollinearity and omitted variable bias are discussed. Relative weight analysis is ideal for testing theoretical models and research hypotheses when survey data are obtained, multicollinearity is present, and there are a large number of independent variables predicting a dependent variable. Thus, relative weight analysis is ideal for testing research hypotheses in logistics and supply chain management.

Genetic Screening in the Workplace: Legislative and Ethical Implications

This paper discusses legal and ethical issues related to genetic screening. It is argued that persons identified with actual or perceived deleterious genetic markers are protected by the American with Disabilities Act of 1990 and the Civil Rights Act of 1991, if members of a protected group, regardless of whether or not they are currently ill. However, legislation may not protect all employees in all scenarios, in which case, ethical principles should guide decision-making. In doing so a model of preventive ethics is proposed to better understand the multiple levels on which this issue resides.     

Import Diversion under European Antidumping Policy

This paper studies empirically the effects of European antidumping cases on trade diversion from importers named in an antidumping investigation, to countries not named in the investigation. For this purpose we use a unique data set at the 8-digit product level. The amount of import diversion can be regarded as an indication of the effectiveness of antidumping policy. We find that trade diversion in the European Union caused by antidumping actions—in contrast to the United States—is limited, suggesting that the European Union's antidumping policy is more effective in keeping imports out. This result holds even after controlling for selection bias in the antidumping investigation procedure. A number of explanations for this difference in trade diversion as a result of antidumping policy between the European Union and United States are formulated.     

心理授权与员工创新行为的关系——心理契约新视角的中介作用

本文研究心理授权对员工创新行为的影响,并引入了员工感知到的“员工对组织的责任”这一心理契约视角为中介变量,通过对不同行业企业进行调查,共收集312份问卷,进行实证研究发现,工作意义、自我决策、自我效能感、影响力对员工创新行为有正向影响;心理契约在工作意义、自我效能感对员工创新行为的关系中起完全中介作用,在自我决策、影响力对员工创新行为的关系中不起中介作用。

An asymmetrical approach to understanding configurations of customer loyalty in the airline industry

This study employs fuzzy set qualitative comparative analysis (fsQCA) to examine asymmetrical relationships among service attributes, relationship quality, and customer loyalty in the airline industry. The study incorporates customers’ demographics and psychological variables to model customer loyalty. Customer loyalty is operationalised as behavioural and attitudinal dimensions in order to capture customers’ actual behaviours and behavioural intentions. Symmetrical testing is also used to compare findings with those from fsQCA application. The study provides various causal recipes or configurations for predicting relationship quality and customer loyalty. The comparison between symmetrical and asymmetrical findings presents deeper and more insightful information. These findings provide useful guidelines and references for the relevant researchers and practitioners. The study also contributes to the literature by utilising symmetrical and asymmetrical tools to advance understanding of antecedent conditions of relationship quality and customer loyalty.

The comprehensive business exam: Usefulness for assessing instructional and student performance outcomes

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.
