Abstract

A growing literature indicates that organizational and work demands place pressure on the partners and families of volunteer workers as it does on paid workers. This study evaluated a conceptual model integrating work–family conflict and stress crossover theoretical frameworks, to investigate the mechanisms by which emergency service volunteer work, specifically, predicts outcomes for the partners of volunteers. Matched data from 102 couples in which one partner was an Australian emergency services volunteer – firefighter, ambulance officer or emergency rescue volunteer – were analysed using structural equation modelling analyses. Findings suggested that one mechanism by which inter-role conflict related to partner adjustment was through elevated withdrawn marital behaviour and decreased intimacy reported by the couple, which indirectly affected partners’ distress. This finding regarding withdrawn behaviour appears to be novel and may also be applicable to paid workers. Alternative mechanisms involving role overload and angry marital behaviour were not supported. These findings extend limited research which has adapted organizational theory to understand processes affecting volunteer workers, and advance conceptual accounts of the mechanisms through which the partners and families of workers are impacted by inter-role conflict.  相似文献

In this paper, we study a single‐product periodic‐review inventory system that faces random and price‐dependent demand. The firm can purchase the product either from option contracts or from the spot market. Different option contracts are offered by a set of suppliers with a two‐part fee structure: a unit reservation cost and a unit exercising cost. The spot market price is random and its realization may affect the subsequent option contract prices. The firm decides the reservation quantity from each supplier and the product selling price at the beginning of each period and the number of options to exercise (inventory replenishment) at the end of the period to maximize the total expected profit over its planning horizon. We show that the optimal inventory replenishment policy is order‐up‐to type with a sequence of decreasing thresholds. We also investigate the optimal option‐reservation policy and the optimal pricing strategy. The optimal reservation quantities and selling price are shown to be both decreasing in the starting inventory level when demand function is additive. Building upon the analytical results, we conduct a numerical study to unveil additional managerial insights. Among other things, we quantify the values of the option contracts and dynamic pricing to the firm and show that they are more significant when the market demand becomes more volatile.  相似文献

Safety climate is an important element of organizational reliability. This study applied benchmarking strategies for monitoring safety climate across nine North Sea oil and gas installations that were surveyed in consecutive years. Examination of absolute changes in safety climate complemented the benchmarking approach. Discriminant function analyses (DFA) identified the elements of safety climate predictive of self-reported accidents; correlational analyses were applied to the scale scores and accident proportions across the year period. Absolute improvements were substantial, with safety climate profiles converging in the second year. Large relative improvements were also observed. DFA highlighted perceived management commitment to safety and willingness to report accidents as significant predictors of personal accident involvement. Changes in perceived management commitment to safety were closely associated with changes in safety behavior.  相似文献

Despite the recognition that poor working relationships can contribute to strain (Chen and Spector 1991, Cooper and Marshall 1978, Kahn and Byosiere lY92, Spector 1987, Spector et al. 1988) and increasing concern over violence and aggression in the workplace (Northwestern National Life Insurance Co. 1993), little research attention has been paid to hostile interpersonal interaction as a work-related stressor. While recent work has focused on interpersonal conflict and sexual harassment as stressors, emotionally abusive interactions have remained largely unaddressed by the organizational stress literature. These interactions are characterized by hostile verbal and non-verbal, non-physical behaviours directed by one or more persons towards another that negatively affect the target's sense of him/herself as a competent person and worker (Keashly et al. 1994, Leymann 1990). The current study examined whether emotional abuse contributed uniquely to understanding work-related stress in student residence assistants (RAs). Seventy-six RAs employed by a Canadian university responded to a questionnaire on the quality of their work experience. The stressors examined were role conflict, role overload, role ambiguity, and number, frequency, and impact of abusive events with dormitory residents. Outcome variables included job-related tension, job satisfaction, job commitment, and intention to leave. Emotional abuse contributed similar amounts of unique variance as the role state stressors to the variables of tension, job satisfaction and intention to leave suggesting emotional abuse is an important and uniquc workplace stressor. Implications of these findings for future research are discussed.  相似文献

Notwithstanding the popularity of outsourcing as a business strategy, the performance benefits realized through outsourcing efforts are observed to be mixed in practice. This leads to important unresolved questions regarding why some firms are able to derive substantial value from their outsourcing initiatives while other firms are left disappointed. This study joins an emerging literature integrating transaction cost economics and capabilities‐based perspectives to develop a deeper understanding of the drivers of outsourcing performance. I develop a theoretical model that examines the independent and joint influence of governance misalignment (i.e., deviation from transaction cost's predicted mode of governance) and a firm's outsourcing capability on the performance of outsourced processes. I test the theoretical model using a dataset of 172 outsourced and 156 in‐house processes. The finding that governance misalignment corresponds to inferior process performance supports transaction cost's discriminating alignment hypothesis. Interestingly, I also find that a retained technical expertise (TE) and outsourcing knowledge management routines (OKMR; both contributors to a firm's outsourcing capability) positively influence outsourcing performance both directly and via their relationship with governance misalignment. While a retained technical expertise and outsourcing knowledge management routines each positively influence outsourcing performance, they do so in distinctive ways. These findings have important managerial implications and make a significant theoretical contribution. Specifically, this study demonstrates that the notion of a governance misalignment is firm‐specific, conditional on the governance capabilities of the organization. This insight underscores the value of integrating transaction cost logic with capabilities‐based perspectives.  相似文献

This study explores how infants encode an object's spatial extent. We habituated 6.5‐month‐old infants to a dowel inside a container and then tested whether they dishabituate to a change in absolute size when the relation between dowel and container is held constant (by altering the size of both container and dowel) and when the relation changes (by altering only the size of the container but not the dowel). Infants only dishabituated when the relation changed, suggesting that they do not encode the absolute size of either object but only the relation between them.  相似文献

Using a randomized controlled effectiveness trial, we examined the effects of Project SUCCESS on a range of secondary outcomes, including the program's mediating variables. Project SUCCESS, which is based both on the Theory of Reasoned Action and on Cognitive Behavior Theory, is a school-based substance use prevention program that targets high-risk students. We recruited two groups of alternative high schools in successive academic years, and randomly assigned schools in each group to either receive the intervention (n = 7) or serve as a control (n = 7). Students completed surveys prior to and following the administration of the program, and again 1 year later. Although participation in Project SUCCESS significantly increased students' perceptions of harm resulting from alcohol and marijuana use, students in the control group reported greater increases in peer support. We also found conflicting evidence in two opposing trends related to students' perceptions of the prevalence and acceptability of substance use. Therefore, the effects of Project SUCCESS on substance use-related beliefs and behaviors must be considered mixed.  相似文献

Quality‐related incidents involving contract manufacturers (CMs) are becoming increasingly prevalent. The quality management (QM) literature, however, has focused mostly on QM within a single firm. Thus, the need for data‐driven research on managing quality with outsourced production is evident. We investigate the use and effectiveness of external failure penalties and audits of CMs’ facilities to manage inter‐firm quality. Building on agency theory and extant QM literature, this study addresses two research questions: (i) whether the control mechanisms of quality audits and contractual external quality failure penalties are substitutes or complements in use and (ii) whether they are substitutes or complements in their effectiveness at aligning the quality interests of customers and their CMs. Our analysis uses dyadic data gathered from brand‐owning firms and their CMs representing 95 contract manufacturing relationships in Food and Drug Administration (FDA)‐regulated industries. The results indicate that more severe external failure penalties correspond to a lower use of facility audits (i.e., they are substitutes‐in‐use). We also find that both external failure penalties and facility audits have a unique positive effect on the CM's perception of relative quality importance. Finally, some evidence supports the hypothesis that each mechanism is more effective in the presence of the other (i.e., they are complements‐in‐effectiveness).  相似文献
