分布式供应链节点企业物流能力柔性价值研究

节点企业物流能力柔性是影响分布式供应链能否快速响应客户的关键因素之一.首先对物流能力的研究进行回顾,分析分布式供应链中节点企业物流能力、特点和运作流程.界定了节点企业物流能力柔性及其价值,通过对物流能力投资过程的分析,在相关合理假设的基础上,分析物流能力投资环节中如何计算不确定性的投资收益,并最终建立基于多段随机规划和实物期权的物流能力柔性价值决策模型.模型中存在的需求的不确定性和决策点的可选择性使求解复杂,因而采用Latin超立方分层采样技术和蒙特卡洛模拟技术对模型进行求解,模型解决了传统财务方法忽视物流能力投资后无形价值计算的问题.最后用案例分析说明该模型在计算节点企业物流能力柔性价值上是有效的.     

决策柔性的一般定义、模型与价值

许多学者和决策实践者认为,决策柔性应当具有价值.但这一直觉推测并未在一般的决策理论框架下得到的证实.文章的目的就是要从理论上证明这一推测.通过回顾关于柔性的文献,归纳出柔性的本质属性(范围和速度).进而在决策理论的一般框架下,给出了决策柔性的数学定义,建立了柔性决策模型,并指出了该模型与经典柔性决策模型之间的关系.最后,应用该模型,证明了"决策选项的价值随着决策(范围和(或)反应)柔性水平的提高而增加"这一基本结论.

Adaptive culture and product/service innovation outcomes

Organizational culture has been used and defined extensively as a relatively stable, enduring set of values, beliefs, assumptions, and symbols shared in the organization. Based on this conception, researchers have studied the relationship between different types of cultures and innovation outcomes. In contrast to this static perspective, the dynamic systems perspective views culture as not necessarily determined by internalized and shared values. Rather, as cultures are constantly receiving environmental pressures that require continuous adaptation, they have an inherent attribute of change, which has been called adaptive culture. We focus on adaptive culture as an antecedent of product/service innovation outcomes, since innovations require a progressive upgrading of shared values, assumptions, and beliefs. Based on the thinking and acting schema, we propose two determinants of adaptive culture that help us to understand how culture can evolve to facilitate product/service innovation outcomes. We propose that structural flexibility and reflexive learning positively affect product/service innovation outcomes by creating an adaptive culture. A 190-company sample is used to analyze the theoretical model variables’ relationship to a culture that can change its values to improve product/service innovation outcomes. The results support the theoretical model, and lead to some implications for the management of culture.     

Self-help for stress and burnout without therapist contact: An online randomised controlled trial

Interventions designed to reduce stress and burnout may be costly and access is limited. This study examined the effectiveness of a self-help book, using Acceptance and commitment therapy (ACT) to target stress and burnout in a randomised controlled online trial without any therapist contact. Participants were recruited through a newsletter of a health insurance company. Participants (N?=?119) who reported at least moderate levels of stress were randomly assigned to an immediate intervention (n?=?61) or a waitlist group (n?=?58). Measures before and after the intervention assessed stress, burnout (primary outcomes), depression, well-being, emotion regulation (secondary outcomes) and ACT-specific constructs. Compared to the waitlist group, participants in the immediate intervention group reported lower stress and burnout and higher psychological flexibility at post-assessment. Effects between groups were large for stress (d?=?0.9), moderate to large for burnout (d?=?0.5–0.8) and large for psychological flexibility (d?=?0.8). All primary and most secondary outcomes and ACT processes continued to improve in the 3-month-follow-up period. Results suggest that an ACT self-help book without any therapist contact is effective in reducing stress and burnout for various occupations. Thus, it may provide a cost-effective public health intervention for reducing stress and burnout.     

Involuntary vs. voluntary flexible work: insights for scholars and stakeholders

ABSTRACT

Building on insights from the early stages of our research partnership with a U.S. Fortune 500 organization, we came to differentiate between voluntary and involuntary schedule variability and remote work. This differentiation underscores the complexity behind flexible schedules and remote work, especially among white-collar, salaried professionals. We collected survey data among the partner firm's information technology (IT) workforce to evaluate whether these forms of flexibility had different implications for workers, as part of the larger Work, Family, and Health Network Study. We find that a significant minority of these employees report working variable schedules and working at home involuntarily. Involuntary variable schedules are associated with greater work-to-family conflict, stress, burnout, turnover intentions, and lower job satisfaction in models that adjust for personal characteristics, job, work hours, family demands, and other factors. Voluntary remote work, in contrast, is protective and more common in this professional sample. Employees working at least 20% of their hours at home and reporting moderate or high choice over where they work have lower stress and intentions to leave the firm. These findings point to the importance of both stakeholders and scholars distinguishing between voluntary and involuntary forms of flexibility, even in a relatively advantaged workforce.     

Promoting business model innovation through social media strategic capability: A moderated mediation model

The rapid development of social media has significantly affected organizational innovation activities. However, scant research has investigated how social media, as an important innovative tool within the corporate landscape, influences firm business model innovation (BMI). This paper provides an initial investigation into whether, and how, social media can be used to promote firm BMI. Drawing on the strategic capability literature, the study examines the relationship between social media strategic capability (SMSC) and BMI by focusing on the mediating role of strategic flexibility and the moderating effects of top management team (TMT) heterogeneity and environmental dynamism. Empirical results from a sample of 283 Chinese firms with two key informants each show a significant and positive association between SMSC and BMI, which is mediated by strategic flexibility. In addition, moderated path analyses indicate that TMT heterogeneity positively moderates the SMSC–strategic flexibility path, while environmental dynamism positively moderates the strategic flexibility–BMI path in the mediated relationship. Theoretical and practical implications of this study for both social media and BMI research are discussed.
