Integrating sustainable supply chain practices with operational performance: an exploratory study of Chinese SMEs

Abstract

With growing regulatory and market pressure to implement green practices, SMEs are facing enormous challenges to simultaneously improve operational and green performances of their supply chains. The paper aims to understand the green practices adopted by Chinese SMEs in the packaging sector in order to assess the impact of these practices in improving the operational performance. Case study-based research methodology is adopted and semi-structured interviews are conducted to collect data from seven SMEs in this study. Both in-case and cross-case analyses are performed to understand the green practices being adopted with the focus on improving the operational performance. The findings of this study indicate that although most SMEs understand the importance of green practices, they have limited knowledge to integrate these practices to improve operational performance. Integration and alignment of green activities with the operational improvement measures are identified as critical factors to develop an efficient green supply chain.     

Crossover of resources and well-being within employee-partner dyads: through increased schedule control

ABSTRACT

This study examined whether one partner’s additional resources obtained from a workplace intervention influence the other partner’s perception of having those resources at home (crossover of resources). We also examined whether one partner’s decreased stress by increased work resources crosses over to the other partner’s stress levels (crossover of well-being). Longitudinal data came from IT employees and their married/cohabiting partners in midlife (N?=?327). A randomized workplace intervention significantly increased employee-reported schedule control at the 6-month follow-up, which, in turn, increased partner-reported employees’ work schedule flexibility to handle family responsibilities at the 12-month follow-up. The intervention also decreased partners’ perceived stress at the 12-month follow-up through the processes by which increases in schedule control predicted decreases in employees’ perceived stress, which further predicted decreased levels of partners’ perceived stress. Notably, crossover of resources and well-being were found in couples who lived with children in the household, but not in couples without children. Our findings suggest that benefits of workplace support can permeate into the family domain, by increasing partner-perceived family resources and well-being.     

Geodesic Lagrangian Monte Carlo over the space of positive definite matrices: with application to Bayesian spectral density estimation

We present geodesic Lagrangian Monte Carlo, an extension of Hamiltonian Monte Carlo for sampling from posterior distributions defined on general Riemannian manifolds. We apply this new algorithm to Bayesian inference on symmetric or Hermitian positive definite (PD) matrices. To do so, we exploit the Riemannian structure induced by Cartan's canonical metric. The geodesics that correspond to this metric are available in closed-form and – within the context of Lagrangian Monte Carlo – provide a principled way to travel around the space of PD matrices. Our method improves Bayesian inference on such matrices by allowing for a broad range of priors, so we are not limited to conjugate priors only. In the context of spectral density estimation, we use the (non-conjugate) complex reference prior as an example modelling option made available by the algorithm. Results based on simulated and real-world multivariate time series are presented in this context, and future directions are outlined.     

Health Outcomes in Individuals with Problem and Pathological Gambling: An Analysis of the 2014 North Carolina Behavioral Risk Factor Survey System (BRFSS)

Problem and pathological gambling refers to subclinical and clinical levels of maladaptive gambling, respectively, and is associated with specific sociodemographic characteristics as well as a number of poor health outcomes. We examined such demographic, physical health, mental health, and health-related behaviors in a sample of 7045 low-risk gamblers and 244 problem/pathological gamblers. Participants completed the 2014 North Carolina Behavioral Risk Factor Surveillance System telephone survey. Using the National Opinion Research Center’s Diagnostic Screen for Gambling Disorders-CLiP, participants were categorized as either “problem/pathological gamblers” or “low-risk gamblers.” Problem/pathological gamblers were younger, more likely to be male, of ethnic minority status, unmarried, and of lower education than low-risk gamblers. No physical health variables differentiated the groups but problem/pathological gamblers reported experiencing significantly more adverse childhood experiences and engaging in significantly more tobacco and alcohol use compared to low-risk gamblers. Moreover, gender moderated relationships between gambling group and several of the alcohol use variables such that male problem/pathological gamblers exhibited greater alcohol use behavior than male low-risk gamblers but no such relationship was present in females. Overall, this study expands the current knowledgebase on disordered gambling and highlights the need to assess disordered gambling in public health samples. Clinical implications are discussed.     

In Search of Housing: Urban Families in Rural Contexts*

Researchers have been following a trend posited by the renowned anthropologist Janet Fitchen, which examines the increasing movement of low‐income people to rural communities drawn not necessarily by labor market forces, but by the characteristics and amenities found in rural towns. This study adds to that literature by focusing on the ways in which public housing availability, changes in housing policy, and rural economic restructuring create opportunities for low‐income families to relocate from urban to rural communities in search of affordable housing. Data collected from an ethnographic sample addressed the following questions: (1) what motivates individuals and families to leave their urban neighborhoods and relocate to rural towns and (2) what challenges do individuals and families have in sustaining stable housing in rural communities? Two main sets of literature relevant to this discussion include studies of patterns of residential mobility and explanations of rural economic restructuring. Both form the conceptual approach of this article by offering a framework to better understand the housing choices and behaviors of low‐income families and the contexts in which these actions are situated.     

The “new” military and income inequality: A cross national analysis

Military expenditures have escalated over the last three decades in both developed and less developed countries, without a corresponding expansion of military personnel. Spending has instead been directed towards hi-tech weaponry, what we refer to as the “new” military. We hypothesize that this new, increasingly capital-intensive military is no longer a pathway of upward mobility or employer of last resort for many uneducated, unskilled, or unemployed people, with significant consequences for those individuals and society as a whole. One such consequence, we argue, is an increase in income inequality. We test this hypothesis with cross-national panel models, estimated for 82 developed and less developed countries from 1970 to 2000. Findings indicate that military capital-intensiveness, as measured by military expenditures per soldier, exacerbates income inequality net of control variables. Neither total military expenditures/GDP nor military participation has a significant effect. It appears from these findings that today’s “new” military establishment is abrogating its historical role as an equalizing force in society, with important policy implications.     

Bureaucratic encounters “after neoliberalism”: Examining the supportive turn in social housing governance

It is well established that encounters between welfare bureaucracies and their clients have been reconfigured under neoliberalism to address the problem of “welfare dependency.” Contemporary bureaucratic encounters therefore entail measures to activate clients’ entrepreneurial/self-governing capacities, and conditionality/sanctioning practices to deal with clients who behave “irresponsibly.” Despite the dominance of the neoliberal model, recent research has identified a counter-trend in the practices of housing services away from entrepreneurializing and punitive strategies and towards a more supportive approach. This paper examines this counter-trend and its implications for neoliberal welfare governance. To do this, it presents findings from research into social housing governance in Queensland, Australia, where the neoliberal focus on welfare independence, conditionality and sanctioning has been tempered by a new supportive approach focused on assisting vulnerable clients to maintain and benefit from access to welfare/housing support. Following Larner, we argue that this shift signals the emergence of an “after neoliberal” governmental formation, wherein key features of neoliberal governmentality are replaced by, or redeployed in the service of, progressive initiatives that address neoliberalism’s failings at the street level, but leave broader neoliberal policy settings undisturbed. We also challenge recent sociological accounts that construe supportive welfare practices as a function of an all-encompassing neoliberal project, arguing instead for appreciation of the contingency of these developments and the progressive political affordances that they entail.     

On the versatility of Little’s Law in operations management: a review and classification using vignettes

Abstract

Despite Little’s Law being considered as one of the ‘laws’ of operations management, evidence of its application in an empirical context is diverse and diffuse. Hence, this paper aims to identify, classify and consolidate published empirical applications of Little’s Law in a systematic manner to better understand its versatility. This paper undertakes a systematic literature review of the databases of the five main publishers of operations management journals and snowball sampling for additional papers. A final sample of 128 empirical journal articles is identified and categorized. Tactical, medium-term decisions relating to capacity dynamics and operations re-engineering are the most popular categories. To give further insights into versatility, vignettes for each category are developed. The review and vignettes confirm Little’s Law as a highly relevant paradigm to operations management decisions due to its empirical versatility across levels, sectors and time domains. The paper suggests four factors to underline the empirical versatility of Little’s Law in operations management: applicability, utility, simplicity and visibility.     

The propagation of lean thinking in SMEs

Abstract

Small and Medium-sized Enterprises (SMEs) play a pivotal role in economic growth, industrial output, and employment creation. However, SMEs are often ignored by researchers as far as the adoption of lean is concerned in comparison to Large Enterprises (LEs). Therefore, the literature regarding lean implementation in SMEs is not conspicuous, and many SMEs have only a limited understanding and awareness of lean. This paper offers a comprehensive literature review with a focus on the implementation of lean in SMEs and explores the applicability of lean thinking in such environments. An attempt is made to provide an analysis of lean practices that have been applied in SMEs and critical success factors for lean transformation in SMEs. It also contributes to the field of lean implementation research by proposing a framework for lean in SMEs and identifies the scope of future research.
