Organizational cynicism: Spillover effects on supervisor–subordinate relationships and performance

Organizational cynicism has grown in contemporary Western organizations. However, its impact on interpersonal relationships and consequently on organizational functioning remains understudied. The present study addresses these gaps by: a) exploring the spillover effect of organizational cynicism on supervisor–subordinate relationships, and b) examining if the spillover effect extends to employee performance. Specifically, it examines if affective commitment to the supervisor mediates the relationship between the PSS × organizational cynicism interaction effect and performance (i.e., mediated-moderation). Data were collected from both employees and supervisors (N = 274) from 45 organizations. Our results generally support our hypotheses. This study provides evidence that organizational cynicism interferes in the relationship employees develop with their supervisors, with consequences to performance. This study opens new avenues for research on organizational cynicism and carries implications for theory and practice.     

Job insecurity and work outcomes: The role of psychological contract breach and positive psychological capital

Job insecurity has received growing attention from researchers because it poses serious challenges for organisations and for society as a whole. However, there are insufficient studies about the processes through which job insecurity affects outcomes as well as potential ways to reduce its negative impact. This study focuses on the relationship between job insecurity and individual-level outcomes (in-role performance and organisational deviance) and examines if (a) job insecurity is positively and/or negatively related to work outcomes, (b) psychological contract breach acts as a mediator of the relationship between job insecurity and work outcomes, and (c) positive psychological capital (PsyCap) buffers the job insecurity–work outcomes relationship via psychological contract breach. With a sample of 362 employee–supervisor dyads, in which the outcome measures were collected from the supervisors, we found support for our hypotheses. Specifically, we found a moderated mediation effect, whereby PsyCap moderates the negative indirect relationship of job insecurity on outcomes through psychological contract breach.     

Complying with voluntary codes of conduct: Corporate strategies for the Valdez Principles

The Valdez Principles is the latest of a series of voluntary codes of conduct that have been enunciated by various advocacy groups to guide the behavior of business enterprises. These principles provide guidelines on corporate conduct towards the environment and present a corporation with critical choices. This study suggests alternative strategies that firms may adopt to cope with this new code. Experience with the Sullivan and MacBride Principles is analyzed to serve as the basis to predict corporate response to the Valdez Principles.     

Ascertaining the effect of planned organizational change on the work environment

In a dynamic environment, organizations often are required to effect major changes in operations. The success of such changes invariably depends upon numerous factors one of which is how the change affects the work environment. Therefore, in planning organizational change it is important to consider the work environment and to objectively evaluate changes in the work environment in a timely fashion so that corrective actions may be formulated if needed. Such framing and monitoring of the organizational change facilitates successful implementation of the organizational change. This paper suggests a measure which may be used in evaluating an organization's work environment. A case is discussed.     

Generalized Jackknife-Based Estimators for Univariate Extreme-Value Modeling

In this article, we revisit the importance of the generalized jackknife in the construction of reliable semi-parametric estimates of some parameters of extreme or even rare events. The generalized jackknife statistic is applied to a minimum-variance reduced-bias estimator of a positive extreme value index—a primary parameter in statistics of extremes. A couple of refinements are proposed and a simulation study shows that these are able to achieve a lower mean square error. A real data illustration is also provided.     

Integrated scheduling and inventory management of an oil products distribution system

The oil supply chain is facing new challenges due to emerging issues such as new alternative energy sources, oil sources scarcity, and price variability with high impact on demand and production and profit margins reduction. Additionally, the existence of large, complex and world wide spread businesses implies a complex system to be managed where distribution can be seen as one of the key areas that needs to be efficiently and effectively managed. Different types of distribution modes characterize the oil supply chain where the pipeline mode is one of the most complex to operate when having multiproduct characteristics. This paper addresses the planning of a generic oil derivatives transportation system characterized by a multiproduct pipeline that connects a single refinery to a storage tank farm. Two alternative mixed integer linear programming models (MILP) that aim to attain a set of planning objectives such as fulfilling costumers’ demands (which is mandatory) while minimizing the medium flow rate are developed. Additionally, final inventory levels are avoided to be excessively low. A real world scenario of a Portuguese company is used to validate and compare the two alternative MILP models developed in this paper.     

The Fabricare system: a multi-agent-based scheduling prototype

Several trends in society in general, and manufacturing in particular, have changed the way business was made in the last decades of the 20th century, setting new requirements for companies and individuals. The research question being addressed in this paper is concerned with the ability to build computer-supported manufacturing systems able to cope with current and future requirements. For this matter, a hypothesis based on the holonic and multi-agent paradigms is proposed. The paper describes a holonic architecture for manufacturing enterprises and a prototype system (named Fabricare) for manufacturing orders scheduling based on that architecture. A negotiation mechanism called ‘contract net with constraint propagation protocol’ was developed for regulating the interaction between holons in the system. This protocol also implements a negotiation-driven scheduling procedure.     

Does the Internet matter for strong ties? Bonding social capital,Internet use,and age-based inequality

As the Internet becomes pervasive in western societies, social capital emerges as a valuable sociological tool to analyze the social effects of Internet use. Thus, a growing body of research has been looking into the relationship between social capital and Internet usage. This research has been showing a positive relationship between them; however, results are not as conclusive when we consider one of the main dimensions of social capital: bonding. Bonding relates to resources that are embedded in one’s strong ties (i.e., family members and close friends). The study of bonding is of particular sociological interest, since the discussion around the social effects of the Internet still suggests that it takes time away from strong ties and that is more useful to connect with weak ties (i.e., acquaintances). This study examines the relationship between bonding and the Internet, using representative survey data and semi-structured interviews from Portugal. Findings show that bonding is predicted positively by Internet use but negatively by age. On one hand, the Internet seems to compensate for the negative age effect because older adults who use it are more likely to have a high level of bonding. On the other hand, the Internet reinforces accumulated social advantage.     

Does country-risk influence electricity production worldwide?

This paper investigates the relationship between country-risks (or conflicts) within countries and electricity production. The determinants of electricity production have been neglected in the literature that favours the relationship between energy consumption, growth and development, and despite of the major challenges on electricity supply systems. We empirically establish that weighted conflict index, as well as sub-items as anti-government demonstrations, government crises and riots negatively influence electricity production per capita, after controlling for income per capita. Country conflicts affect electricity production mostly in the long-run. Our results imply that conflicts may affect electricity production substantially and consequently the economy as a whole. Policy should emphasize the institutional framework to avoid conflicts within countries in order to secure electricity production.
