Model of ageing inception and growth from microvoids in polyethylene-based materials under AC voltage
2008
Several degradation mechanisms may affect polymeric insulation system reliability. Some authors postulate that, even in a perfect dielectric, nanoscale cavities can enlarge due to various mechanisms (from mechanical fatigue to lowering of the degradation reaction energy barrier) up to a point where highly energetic phenomena, which bring about breakdown, can be incepted. Other authors are more focused on the inherent limits of manufacturing processes, which leave cavities within the insulation system whose size is large enough to cause electron avalanches, thus a measurable partial discharge (PD) activity, from the time the system is put in service or as a function of external factors (e.g.…
Comparing motivational, self-regulatory and habitual processes in a computer-tailored physical activity intervention in hospital employees - protocol…
2017
Abstract Background Most people do not engage in sufficient physical activity to confer health benefits and to reduce risk of chronic disease. Healthcare professionals frequently provide guidance on physical activity, but often do not meet guideline levels of physical activity themselves. The main objective of this study is to develop and test the efficacy of a tailored intervention to increase healthcare professionals’ physical activity participation and quality of life, and to reduce work-related stress and absenteeism. This is the first study to compare the additive effects of three forms of a tailored intervention using different techniques from behavioural theory, which differ accordin…
The Impact of the Direct Participation of Workers on the Rates of Absenteeism in the Spanish Labor Environment.
2020
The aim of this research was to study the relationship between the different levels of direct participation of workers (passive, consultative or active-delegated) in risk prevention management with the levels of absenteeism in Spain. To this end, a transversal study was carried out using microdata from the Second European Survey of Companies on New and Emerging Risks (ESENER-2-Spain, 2014) with a master population of 3162 work centres. A multinomial logistic regression model was carried out, with the dependent variable being the levels of absenteeism and the independent variables, the participation indicators and preventive management, calculating the adjusted odds ratio (aOR) between all t…
Repérer, reconnaître et prévenir les risques psychosociaux : une analyse institutionnelle et économique du cas français
2017
In France, psychosocial risks (PSR) became a major concern for society by their stakes in termsof public health, costs for companies and workers. In the late 2000s, the Ministries of Labor and Health took up these challenges by initiating surveys, data collection and scientific works. Despite the development of knowledge about PSR and its consequences, the integration of these new risks into public and managerial policies is still very modest.Through an economic, institutional and empirical analysis, the main objective of this thesis is to contribute to a better knowledge of the consequences of PSR’ exposure for individual and for company, and to analyze the role of prevention authorities t…
Gender Peer Effects in University: Evidence from a Randomized Experiment
2010
Recent studies for primary and secondary education find positive effects of the share of girls in the classroom on achievement of boys and girls. This study examines whether these results can be extrapolated to post-secondary education. We conduct an experiment in which the shares of girls in workgroups for first year students in economics and business are manipulated and students are randomly assigned to these groups. Boys tend to postpone their dropout decision when surrounded by more girls, and there is also a modest reduction in early absenteeism. On the other hand, boys perform worse on courses with high math content when assigned to a group with many girls. Overall, however, we fail t…
Absentismo escolar en España. Datos y reflexiones
2020
El absentismo escolar no recibe en España la atención que merece. Pese a que diversos estudios señalan que la ausencia de las aulas del alumnado en edad de escolarización obligatoria es más amplia de lo que parece ‒los informes PISA, por ejemplo, lo cuantifican entre el 25 y el 28 % del alumnado de 4º de la secundaria obligatoria‒ esta realidad presenta una escasa visibilidad educativa y social. En el trabajo se realiza una primera clarificación conceptual del problema, para posteriormente analizar con un enfoque integral la normativa legal que articula en nuestro país: el derecho a la educación; la escolarización obligatoria y el absentismo. A partir de ese marco teórico, se señalan los tr…
Leaders as role models: Effects of leader presenteeism on employee presenteeism and sick leave
2020
There is a broad consensus that associations exist between leadership behaviour and employee health. However, much less is known about potential mediating processes underlying links between specifi...
767 Healthy enterprise standard(hes) evaluation: analysing effects and cost-benefit results with a qualitative evaluation of implementation process
2018
Introduction The Healthy Enterprise Standard (HES) is related to a certification program in Quebec (Canada) and targets four areas: Lifestyle, Work-life balance, Workplace environment and Management practices. The aim of this study was to open the black box of intervention and analyse the implementation process in order to interpret effects of HES on health and workplace risk factors, and cost-benefit results from the employer’s perspective. Methods We used a before-after design for a two-case analysis with a mixed-method approach. In two organisations from different sectors, quantitative data were collected with a questionnaire among all active workers before the standard’s implementation …
Brazilian Teachers' Absenteeism: Work Design Predictive Model
2021
Sickness-related absenteeism in teachers represents financial, social, and human costs. This study aimed to analyze the relationship between work characteristics and lengths of absence. The main hypothesis is that different work characteristics are predictors of different lengths of absenteeism. In total, 1,530 teachers participated in the study. The results supported the main hypothesis and suggested that physical demands, task identity, and job complexity are useful to explain absenteeism. It is concluded that analyzing different absenteeism lengths makes it possible to broaden the phenomenon discussion and qualify the relationship between work characteristics and absenteeism. This study …
Wittgenstein’s “Inner and Outer”: Overcoming Epistemic Asymmetry
2013
In this article, I identify three ways in which Wittgenstein opposed an idea of epistemic asymmetry between the first person and the secondor-third person. Examining the questions of 1) absence of doubt about my own experience and uncertainty about the experiences of others, 2) ineffability of subjective experience and 3) immediacy of my knowledge of my own experience contrasted with my merely inferential knowledge about the experiences of others, I see Wittgenstein’s remarks about “inner and outer” as a many-faceted denial of the claim that people’s minds are in some deep way unknowable to others. These considerations also serve to clarify Wittgenstein’s relation to behaviorism. 1. Wittgen…
