This study tests the relationships between workaholism (i.e. working excessively and compulsively), sleep problems and cardiovascular risk in 537 employees from five Spanish hospitals. Four types of worker (i.e. workaholics, positive workers, compulsive workers and hard workers) were distinguished, and their health indicators were compared. The results showed that workaholics experienced significantly more sleep problems (i.e. morning tiredness, sleeping while driving and sleeping fewer hours both on weekdays and at weekends, with poorer quality), had higher relative risk scores, and consumed more caffeine and alcohol than the other patterns of worker (positive, compulsive and hard workers). Further analyses revealed that sleep problems fully mediated the relationship between workaholism (i.e. working excessively and compulsively) and cardiovascular risk. The study emphasizes the fact that being a workaholic might be a significant risk factor for having sleep problems and cardiovascular disease. 相似文献

Identifying design criteria for urban system ‘last-mile’ solutions – a multi-stakeholder perspective
AbstractThis study presents a novel approach to design and evaluate ‘last-mile’ solutions – encompassing the social and economic perspectives of key stakeholders. While urban system initiatives have been implemented in practice, theoretical gaps remain at the operational design level. A theoretical framework is developed, based on design criteria identified from a critical synthesis of supply chain and operations management literature, and ‘operationalised’ using an in-depth case study demonstrating implementation of a Consumer Choice Portal-Package Consolidation Centre solution, within a densely populated urban geography. Findings suggest that there is a need to re-define the role of institutional actors beyond that of the traditional governance task, to one of being able to facilitate performance outcomes. Similarly, industrial efficiency dimensions need to be reorientated to include consumer participation, social considerations and multi-stakeholder service outcomes. Finally, implications for operations theory and practising managers in city logistics are highlighted, with suggested directions for future research. 相似文献

This paper aims to contribute to the empirical evidence relating corporate social responsibility (CSR), board composition, and firm performance. Using a sample of Spanish listed firms included in the IBEX 35 over the period 2005–2010 the results show that the percentage of independent directors affect firm CSR activities, and that this effect is moderated by the resources available to the firm (measured by return on assets). Also, the CSR has a mediating role on the relation between the independence of the board of directors and firm value. These results hold for other board characteristics (board size and women as directors). 相似文献

This literature review analyzes leading international business and management journals from 2000 to 2012 in order to explore the role of national culture in international business research. Through the analysis of the 265 selected articles, the study thematically maps the field and identifies research challenges and opportunities. It reflects on avenues for future research related to both thematic and methodological issues, among them: research focused on the impact of the home/host national culture on internationalization processes (as existing literature mainly focuses on cultural distance); the role to be played by new theoretical frameworks; and the need to consider cultural positions and cultural friction rather than traditional cultural distance when analyzing internationalization decisions. 相似文献

The rationalization of a choice function, in terms of assumptions that involve expansion or contraction properties of the feasible set, over non-finite sets is analyzed. Schwartz's results (1976), stated in the finite case, are extended to this more general framework. Moreover, a characterization result when continuity conditions are imposed on the choice function, as well as on the binary relation that rationalizes it, is presented. 相似文献

This paper analyzes the extent to which individual characteristics, the workplace situation, and regional policies influence
the use and duration of parental leave in Spain. The research is based on a sample of 125,165 individuals, and 6,959 parental
leaves covered in the “Muestra Continua de Vidas Laborales” (MCVL-2006). The MCVL consists of administrative register data,
which include information from three different sources: The social security system, municipal and income tax Registers. We
adopt a simultaneous equations approach to analyze the determinants of the use (logistic regression) and duration (event history
analysis) of parental leave, which allows us to control for endogeneity and censored observations. Our results suggest that
the Spanish parental leave scheme increases gender and social inequalities, insofar as it reinforces gender role specialization,
and only encourages the reconciliation of work and family life among workers with a good position in the labor market (educated
employees with a high and stable work status). 相似文献

This paper examines the findings of a survey of the personal, educational and professional profiles of a sample of male and female senior executives of companies operating in Spain. The women were found to be younger; they had fewer children, resorted to more domestic help, and earned less than the men, although they often had higher qualifications. Yet cultural patterns and institutional barriers still prevent them from making full use of their capabilities. In spite of recent legislative efforts to promote gender equity at work, more than nine out of ten senior executives are still men. 相似文献

The objectives of the present study were to analyze the pattern of tobacco use among Spanish adolescents, as well as to determine gender differences in specific risk factors of cigarette use. The study sample was made up of 1,483 boys and 1,358 girls, aged 12-16 (M = 14). Participants were asked to answer an ad-hoc instrument to evaluate the pattern of use, perceived availability, risk of harm, family- and peer-use, engagement in leisure activities, drive for thinness, and self-esteem. Results showed no gender differences in the pattern of use. With regard to risk and protector factors, a predictive analysis showed that peer-related variables were the most determinant for tobacco use both for boys and girls. Some gender differences were also detected: Playing sports was protective for boys only, and listening to music for girls only. Drive for thinness and self-esteem were not related to tobacco use for either boys or girls. These findings help increase our understanding of smoking risk factors in adolescence and to pay special attention to the group of friends when planning prevention programs to reduce risk factors. 相似文献

We aimed to explore the association between age of onset of gambling problems and current psychopathological and clinical
status, personality profile and therapeutic outcome in a sample of pathological gamblers. A total of 904 consecutive pathological
gambling patients were administered several instruments about gambling behavior, psychopathology and personality. They received
a 4-month cognitive-behavioral group treatment. Information of dropouts and relapses during treatment was registered. Older
age of onset of gambling problems was associated with higher general psychopathology (SCL-90-R Paranoid Ideation, Psychoticism,
Depression; P < 0.015). Younger age of onset was related to greater severity of pathological gambling (P < 0.015), higher novelty seeking, and lower self-directedness (P < 0.015). No statistically significant association was found between age of onset and relapse and dropouts during treatment.
Age of onset of gambling problems seems to influence the clinical presentation of pathological gambling but not treatment
outcome. 相似文献

Partial linear modelling ideas have recently been adapted to situations when functional data are observed. This paper aims
to complete the study of such model by proposing a fully automatic estimation procedure. This is achieved by constructing
a data-driven method to choose the smoothing parameters entered in the nonparametric components of the model. The asymptotic
optimality of the method is stated and its practical interest is illustrated on finite size Monte Carlo simulated samples. 相似文献
