With the emergence of the Industrial Internet of Things (IIoT), process industries have started to adopt wireless sensor-actuator networks (WSANs) for control applications. It is crucial to achieve real-time communication in this emerging class of networks, and routing has significant impacts on end-to-end communication delays in WSANs. However, despite considerable research on real-time transm...

BACKGROUND Associations between job stresses, as assessed by theoretical job stress model and depressive symptoms among fire fighters have not been fully investigated. The purpose of this study is to clarify the factors of job stress that influence the depressive symptoms in Japanese fire fighters. METHODS The subjects involved 1,672 fire fighters from a local government. The questionnaire co...

Propositional satisfiability (SAT) solvers based on conflict directed clause learning (CDCL) implicitly produce resolution refutations of unsatisfiable formulas. The precise class of formulas for which they can produce polynomial size refutations has been the subject of several studies, with special focus on the clause learning aspect of these solvers. The results, however, assume the use of no...

There is a burgeoning amount of research into happiness and greatly increased popular attention, so it seems logical to add a course on happiness to the university curriculum. We encountered, in developing and running such a course, a number of dilemmas that the topic of happiness makes especially acute. Should the teacher remain separate from the class, as an authority, or participate in group...

BACKGROUND Over the past few decades, the association between leisure activity patterns and marital conflict or satisfaction has been studied extensively. However, most studies to date have been limited to middle-class families of developed societies, and an investigation of the issue, from a developing country perspective like Iran, is non-existent. OBJECTIVES In an observational, analytical...

This article offers policymakers and researchers pragmatic sustainable approaches to identify mitigate conflict threats by looking beyond p-values plausible instruments. We argue that predicting successfully depends on the choice of algorithms, which, if chosen accurately, can reduce economic social instabilities caused post-conflict reconstruction. After collating data with variables linked co...

Against premature claims about the declining political relevance of social class in post-industrial democracies, recent research indicates that continues to be a relevant determinant preferences. In societies ‘old’ divides on economic issues coexist with ‘new’ alignments cultural topics. While there is cumulated evidence classes’ distinct placement these issues, this paper argues strength depen...
