Increasing socio-economic status is associated with increasing levels of subjective well-being. Subjective well-being is in turn associated with physical and mental health. In this study, socio-economic gradients in subjective well-being are investigated in a large cross-section of the British population. Higher socioeconomic groups are more satisfied with life and have fewer psychosomatic symp...

The present study aims at exploring predictors influencing mathematics performance. More in particular, the study focuses on internal students‟ characteristics (gender, age, metacognitive experience, mathematics self-efficacy) and external contextual factors (GDP of school location, parents‟ educational level, teachers‟ educational level, and teacher beliefs). A sample of 1 749 students and 91 ...

A natural generalization of the criticality notion in a network with fuzzy activity times is given. It consists in direct application of the extension principle of Zadeh to the notion of criticality of a path (an activity, an event) treated as a function of the activities duration times in the network. There are shown some relations between the notion of fuzzy criticality, introduced in the pap...

The construction and application of an indoor spatial data model is an important prerequisite to meet the requirements of diversified indoor spatial location services. The traditional indoor spatial topology model focuses on the construction of topology information. It has high path analysis and query efficiency, but ignores the spatial location information. The grid model retains the plane pos...

The aim of the present study was to find underlying factors of social capital acquisition in online gaming communities (guilds). 391 players of World of Warcraft were asked about their playing habits, their behavior towards fellow players and the bridging and bonding social capital they received by playing.

We prove a longstanding conjecture [Lyons, T. J.; Differential equations driven by rough signals. Rev. Mat. Iberoamericana 14 (1998), no. 2, 215—310] concerning the applicability of rough path analysis for stochastic partial differential equations arising from the theory of non-linear filtering.

The main goal of this study is to present a multidimensional structure for relationship between Supply Chain Strategies, Business Strategies, and Knowledge Management Strategies with Knowledge Sharing in Supply Chain of the Automotive Industry of Iran. This is an applied research and has done as a Survey, Correlation and cause-effect research. In this research, confirmative factor analysis, cor...

Introduction: Unit risk management is a critical component of gas refining management, as risks that are not well-managed may lead to trip production failures. The present study aimed to provide a structural model for investigating the role and effect of different variables on stopping the gas production process in the gas refinery. Material and Methods: This study was a retrospective cross-se...

The study, comparing di€erent driver licensing methods, involved 267 subjects (132 male, 135 female) with a mean age of 19.6 years (range 17±23) who had obtained their driver's licence either by completing a competency-based training course (145 subjects) or by passing a practical examination (122 subjects). Subjects completed a survey regarding their driving attitudes, behaviours and experienc...
