The purpose of this paper is to focus on the suitability of the multitrait-multimethod (MTMM) matrix approach for examining construct validity in human resource management (HRM) research. The authors also provide a number of suggestions on how to use MTMM more effectively in HRM research.

The authors start by presenting a basic introduction to MTMM approach. Next the authors briefly review the limitations of MTMM approach and suggested improvements. The authors elaborate on these limitations by providing HRM examples. To further illustrate these issues, the authors review employment interview research.

The construct validity analysis in HRM research suffers from three problematic assumptions of the classical MTMM approach: uncorrelated trait-method units, uncorrelated methods, and uncorrelated traits. The review of interview research shows that classical MTMM approach is by far the most popular approach given its relative simplicity and modest sample size requirements. This popularity stresses the significance of the review in highlighting these issues.

Several improvements to quantify the interpretations of MTMM analysis are available to researchers. This review closely examines how these limitations and proposed improvements influence HRM research, thereby making the methodological advances concerning the MTMM approach more accessible to HRM researchers and practitioners.

The purpose of this paper is to investigate how individual interviewers’ dispositional cognitive motivations may influence interview interactions and outcomes. More specifically, this study explores the influence of the need for cognition, need for cognitive closure, and accountability on the relationship between first impressions and selection decisions.

In total, 41 graduate students were assigned the role of interviewers and were tasked to interview 331 undergraduate students at a large Midwestern university. The selection interview was designed to recruit qualified undergraduate students to the MBA program of the university.

First impressions significantly influenced selection decisions, but did not influence interviewers’ behaviors. Moreover, multilevel analyses reveal that interviewers’ need for cognition and accountability moderate the relationship between first impression and selection decisions, albeit in different direction. Need for cognition strengthens, whereas accountability weakens the relationship between first impression and selection decision.

A potential interviewer bias is apparent, where interviewers high on need for cognition tend to weight first impressions more in the decision process. However, this bias was not directly observable, since interviewers’ behaviors during the interview were not affected by first impressions.

The present study goes beyond previous research on first impressions in the employment interview, finding that dispositional differences account for the tendency to weigh first impressions in the selection decision.

Purpose – The purpose of this chapter is to establish some of the reasons why there exists a chasm between micro and macro disciplines of organizational sciences. We aim to suggest some fecund areas for bridging the gap between the micro and macro side of our science.

Methodology/Approach – In this chapter, we have polled our colleagues to ascertain the areas that they believe have the most potential to bridge the micro–macro divide. In addition, we have reviewed extant literature to identify some of the areas where bridging work has already started.

Findings – Through our survey and literature review, we have identified a number of areas which can help in narrowing the micro–macro divide.

Social Implications – By suggesting some ways to bridge the micro–macro divide, this chapter helps in setting future research agenda that will help in viewing organizational problems from multiple lenses. Our work also encourages the scholars from various disciplines to explore ways that can integrate the broad disciplines of organizational sciences.

Originality/Value of Paper – We have attempted to take the pulse of researchers in management disciplines concerning the chasm between micro and macro disciplines, and we have tried to integrate this information with the bridging research that has already been reported. Moreover, we have suggested a number of reasons why this gap is so difficult to remediate. We discuss how bridging the gap is connected to the way in which we train, develop, and reward nascent scholars in our field.

Welcome to volume 6 of Research Methodology in Strategy and Management! In creating this series about eight years ago, our belief was that the organizational sciences needed a forum wherein leading scholars could openly express their views about important and emerging issues within research methods. In particular, we wanted the book series to serve as a metaphorical bridge between areas of inquiry that could benefit from increased interaction with each other. This sixth volume of the series recalls these roots by being built around the theme of “Building methodological bridges.”

This study aims to develop sweet chestnut incorporated corn-based extrudates by the optimization of process conditions.

The independent process variables for extrusion (blend ratio, barrel temperature, screw speed and feed moisture) were investigated to govern their impact on reliant variables, namely, bulk density, specific mechanical energy, water absorption index, water solubility index, color and hardness. Product and system responses were significantly (p < 0.05) affected by the independent variables. Experimental design with quadratic models experienced a high coefficient of determination (R² = 0.99).

Numerical optimization for the development of extrudates resulted in optimum conditions having corn flour: sweet chestnut flour (80:20), barrel temperature (120°C), screw speed (340 rpm) and feed moisture (12%). Fat, moisture and protein contents of the developed extrudates using optimum conditions were significantly (p < 0.05) lower compared to raw materials – corn and sweet chestnut. The packaging of extrudates in aluminum laminates revealed shelf stability of three months at room temperature without deterioration of quality.

Nutritionally rich sweet chestnut extruded products would be an exclusive option to already existing snacks in the market and can facilitate a new sphere in extruded product sector.
