Labor Utilization Effects of Labor Scheduling Flexibility Alternatives in a Tour Scheduling Environment

This study used a factorial experimental design and a new modeling methodology to investigate the impact of a number of labor scheduling flexibility alternatives and labor requirements characteristics on labor utilization within a tour scheduling environment. Break-placement flexibility and shift-length flexibility were found to be extremely effective in improving labor utilization for all labor requirement distributions used. Flexibility with respect to the number of days included in a tour schedule resulted in substantial improvement in labor utilization for all labor requirements distributions exhibiting daily and/or weekly variation. Surprisingly, virtually no improvement in labor utilization was achieved for any labor requirement distribution by the removal of requirements for consecutive days off. In addition, almost no improvement was found by allowing the shift start time to vary across the working days included in tours. High labor requirement amplitude was found to have a strong adverse effect on labor utilization while longer operational days were associated with improved labor utilization for all labor requirement distributions. We discuss the implications of these results for service operations management and provide suggestions for future research.     

Data‐Driven Supply Chain Orientation and Financial Performance: The Moderating Effect of Innovation‐Focused Complementary Assets

Drawing on the complementary assets framework, this study explores the moderating effect of innovation‐focused complementary assets (CA‐I) on the relationship between a data‐driven supply chain orientation (DDSCO) and firm financial performance. To test the moderating effect, survey data gathered from 329 manufacturing firms in China were analysed using a moderated regression analysis. The results indicate that DDSCO has a significant positive effect on financial performance, and that capabilities for product and process innovation function as complementary assets moderating the DDSCO–performance relationship. The findings suggest that innovation‐focused complementary assets are performance differentiators when paired with a DDSCO and explain why some firms obtain financial benefits from the development of a DDSCO while others do not. Specifically, competitive advantage from a DDSCO may not be realized unless CA‐I and potentially other complementary assets are harnessed, thus providing useful practical guidance to managers. Hence, the study provides empirical support for the complementary assets framework.     

How Role Replaced Personality as a Major Category of Sociology

Try to imagine sociology being without the role concept. The thought experiment will strike us as impossible. And yet, through the early decades of the 20th century, remarkably few sociologists thought of social agents as incumbents of social roles and as performing roles in their day to day lives. This article addresses a set of related questions. How did sociologists manage without the concept social role? How did they describe the social agent and his agency? When and in what circumstances was the term social role initially formulated and when did it enter the vocabulary of social science? Ralph Linton’s The Study of Man (1936) is identified as the key text in this history of the concept social role, foreshadowed in writings of Robert Park, E. A. Burgess, and Kimball Young. Linton introduced his role idea in the midst of disciplinary change with boundaries between sociology and psychology (particularly social, and personal, psychology) being redrawn.     

Lowering Inventory Systems Costs by Using Regression-Derived Estimators of Demand Variability*

Scientific techniques for inventory management typically are applied to systems containing many items. Such techniques require an estimation of the demand variance (and mean) of each item from historical data. This research demonstrates a significant potential for improvement in system cost performance from using least-squares regression fits of a variance-to-mean functional relation instead of the standard statistical variance estimate. Even when there is a moderate degree of heterogeneity among items and when the form of the variance-to-mean relation is misspecified, substantial cost savings may be realized. The cost of statistical uncertainty may be reduced by half. The research also provides evidence that system cost is fairly insensitive to the number of items used to fit the regression. This paper provides the underlying reason why a regression-derived variance estimator yields lower cost: it is less variable than the usual individual item variance estimator.     

Challenging the Myths of Black Women—A Short-Term,Structured, Art Experience Group: Exploring the Intersections of Race,Gender, and Intergenerational Trauma

ABSTRACT

The authors describe a short-term structured group process for African American women in the suburbs of Washington, DC, highlighting the perspective of the group leaders. The group was started to address the unique needs of African American women who are also survivors of childhood abuse and neglect. The group leaders used discussion and art in the group to explore the intersections of race, gender, and intergenerational trauma. Having shared experiences with the participants of the group, the authors explore the ways the group leaders were changed and challenged in the process.     

The importance of ergonomics to sustainability throughout a building's life cycle

Protecting and conserving environmental resources is a global concern. Over the past decade, a number of certification processes have emerged to help designers and operators of buildings assess the potential impact of a building on the environment. Certifications such as the Leadership in Energy and Environmental Design (LEED) consider the environmental impact through the lifecycle of a building, but may not be considering the people that construct and utilize it. It is important to remember the human factor. Considering the human factor throughout the lifecycle is crucial to ensure individuals are protected during construction and in operation in the built environment. The paper highlights how ergonomics can be integrated into the life cycle of a building to promote sustainability goals for both the human factor and the environment. A case study approach will be used to illustrate how ergonomics was integrated into a LEED renovation and expanded into its daily operations on a large university campus..     

Gender differences in faculty attrition in the USA

In this study, we examined possible gender differences in reasons for faculty attrition during the last 20 years at a small women's liberal arts college. The attrition rate was calculated from archival data collected through old college directories. As in earlier studies, the attrition rate was higher for women (31%) than for men (18.5%). Reasons for leaving the college were assessed in an online survey completed by 45 out of 66 tenure-track or tenured professors who left (excluding retirees). Work–family conflict was the most frequently cited reason for leaving, with disproportionately more women than men giving this reason. Open-ended responses revealed that work–family conflict typically referred to the difficulty of coordinating two careers. Female faculty who left were also significantly more dissatisfied than males with the support for balancing work and family life at the college. The need for colleges to create spousal policies to help faculty coordinate dual careers was discussed.     

Balancing Control and Coaching in CSO Governance. A Paradox Perspective on Board Behavior

How can the internal governance of civil society organizations be conceptualized more adequately by accounting for the dual and simultaneous requirements of controlling and coaching in board behavior? Empirically, we seem to agree that effective governance of a civil society organization is crucial to its sustained viability. Conceptually, however, we observe a lack of consensus on how to best understand CSO governance. By critically juxtaposing two major theoretical lenses to conceptualize governance, namely, agency and stewardship theory, we identify a number of challenges when dealing with board–management relations that deserve our attention. While agency theory privileges controlling behavior, stewardship theory emphasizes the coaching behavior of boards. The purpose of this article is to offer a concept of governance that is informed by a paradox perspective advancing a subtler, more adequate conceptualization of board governance that accounts for these often conflicting demands on CSO governance. Drawing on illustrations from a longitudinal interpretive case study, we exemplify our propositions empirically. The article concludes with discussing the implications of our argument for CSO governance research and practice.
