A matter of style? testing the moderating effect of driving styles on the relationship between job strain and work-related crashes of professional dr…
2020
Abstract Different empirical studies suggest that both job strain and driving styles are significant contributors to the work-related traffic crashes suffered by professional drivers. Nevertheless, the current evidence falls considerably short when explaining why driving styles may modify (or not) the relationship between occupational stressors and professional drivers’ safety outcomes. The aim of this study was to examine whether driving styles moderate the effect of job strain on professional drivers’ Work Traffic Crashes (WTCs). This research was performed using the data collected from a sample of 753 professional drivers, responding to a self-report questionnaire on job strain (work str…
Self-reported playing time and justice as predictors of coach satisfaction: An analysis of elite ice-hockey and handball players
2020
Intrateam competition for specific roles and playing time is a continuous imperative process in elite sport teams. The assessment of this competition is done by the coach and the outcome of this process has a significant impact on the team and the players. The following hypothesis was put forward for testing: Self-reported playing time and perceptions of justice among elite ice-hockey and handball players predict their satisfaction with the coach. Elite ice-hockey and handball players (N = 231) reported playing time and completed the Perceived Justice and Athlete Satisfaction Questionnaires. Hierarchical multiple regression analyses show that self-reported playing time, distributive justice…
Effects of a brief pre‑admission telephone reminder on no‑show and dropout rates in substance use disorder treatment: a quasi‑experimental study
2022
Abstract Background Appointment no-show and early dropout from treatment represent major challenges in outpatient substance use disorder treatment, adversely affecting clinical outcomes and health care productivity. In this quasi-experimental study, we examined how a brief reminder intervention for new patients before their first appointment affected treatment participation and retention. No-shows (not attending any sessions) and dropouts (discontinuation of initiated treatment because of three consecutively missed appointments) were compared between a period with pre-admission telephone calls (intervention) and a period without such reminders (non-intervention). Methods Participants were a…
Influence of Teacher and Family Support on University Student Motivation and Engagement
2021
Although many studies endorse the notion that the way students perceive support influences their engagement, very few have explored the possible mediator role of intention to learn between these variables. The present work provides new evidence to the existing literature because it analyses the work of intention to learn (measured with expectancy–value beliefs and achievement goals) as a mediating motivational variable in the relation between university students’ external support (teacher and family) and their engagement. The Educational Situation Quality Model (MOCSE, its acronym in Spanish) has employed as a theoretical framework to perform this analysis. A sample of 267 Spanish universit…
Shell matrices of recent rhynchonelliform brachiopods: microstructures and glycosylation studies.
2007
ABSTRACTLike most metazoan biomineralisations, the brachiopod shell is the end product of a biologically controlled calcification process. The main agent of the control is the extracellular matrix, which is secreted by the outer mantle epithelium. This matrix mediates the calcification process by allowing crystal nucleation and elongation in specific orientations and finally, by stopping crystal growth. The proteinaceous moiety of brachiopod shell matrices has been extensively studied. Less known are the post-translational modifications that occur in these matrices, in particular glycosylations. In this comparison of five species of Recent articulated brachiopods, the ratio of soluble to in…
Exploring automatic grouping procedures in ceramic petrology
2004
Although a small number of studies have attempted to introduce automatic grouping procedures into thin section petrography of archaeological ceramics, the majority of studies continue to be carried out by non-automatic means. Although such an approach with the single observer grouping samples has a number of advantages, it is problematic when dealing with large numbers of samples. This paper aims to explore different coding systems and statistical analyses for grouping ceramic thin sections. In the example discussed a number of variables are defined, codified and analysed by correspondence analysis, classical multidimensional scaling, non-metric isotonic multidimensional scaling and Sammon …
NEW FRAMES OF ARCHAEOMETRICAL DESCRIPTION OF SPINDLE WHORLS: A CASE STUDY OF THE LATE ENEOLITHIC SPINDLE WHORLS FROM THE 1C SITE IN GRÓDEK, DISTRICT …
2010
The essential role of yarn spinning in textile production is indisputable. In this context, spindle whorls, the basic spinning accessories that can be found in the archaeological record, are commonly discussed. Even though the importance of the technical specification of spindle whorls has been already recognized by some authors, their functional characteristics are usually limited to the basic parameters affecting their usage range (i.e., weight, diameter and height). And since the mass moment of inertia of spindle whorls is considered to be a salient index when discussing their technical variability, the descriptions are deficient. With this short study, we intend to implement further res…
Economic Feasibility of Measures for Energy Efficiency
2014
In this chapter the economic impact of some measures for energy efficiency, both using automation of technical infrastructures (according to EN 15232) as well as implementing passive measures concerning the use of building materials and techniques (according to EN 15271), is studied. The chapter is organized as follows. First, a technical-economical study on the evaluation of the impact on residential buildings of Building Automation Control, BAC, and Technical Building Management, TBM, systems is presented. Then the same assessment of some passive measures that can be employed is carried out using the Passive House Standard for Mediterranean warm climates is shown. Numerical elaborations h…
