Sheepskin Effects in the Spanish Labour Market: A Public–Private Sector Analysis
2005
ABSTRACT The aim of this paper is to contrast the nature of the effect of education, Human Capital or Screening, in the Spanish labour market. We use the Hungerford and Solon methodology to distinguish between the returns to schooling from mere years of schooling as a reflection of their productive–enhancing contribution (human capital) and the returns to schooling from academic certificates as signals of the individual’s ability (sheepskin effects). We separate our data into public and private sector workers. In the public sector the institutional restriction in the access and in the wage settings might force certificate rewards. Those not necessarily should be interpreted as sheepskin eff…
A problem-adjusted genetic algorithm for flexibility design
2013
Many present markets for goods and services have highly volatile demand due to short life cycles and strong competition in saturated environments. Determination of capacity levels is difficult because capacities often need to be set long before demand realizes. In order to avoid capacity-demand mismatches, operations managers employ mix-flexible resources which allow them to shift excess demands to unused capacities. The Flexibility Design Problem (FDP) models the decision on the optimal configuration of a flexible (manufacturing) network. FDP is a difficult stochastic optimization problem, for which traditional exact approaches are not able to solve but the smallest instances in reasonable…
Work–Family Practices and Complexity of Their Usage: A Discourse Analysis Towards Socially Responsible Human Resource Management
2020
AbstractThe question of work–family practices commonly arises in both theory and daily practice as a matter of responsibility in today’s organisations. More information is needed about them for socially responsible human resource management (SR-HRM). In this article our interest is in how work–family practices, serve as an important element of SR-HRM, constructed as (un)helpful for employees’ work–family integration, are realised in organisational life. We investigate the discursive ways in which members of two different organisations working at different organisational levels construct the issue in the Finnish context. Three discourses were interpreted: (1) a discourse of compliance with e…
Time Use of the Self-Employed
2007
SUMMARY It is a well-documented empirical regularity that it is more satisfying to be self-employed than to work as an employee for an organization. A large part of this difference in job satisfaction is attributed in the literature to the strong perception of independence by the self-employed. In this paper we study people's time use as a source of entrepreneurial independence. By making use of disaggregated sequential microdata on people's time use, we are able to document that the self-employed work longer effective hours, as well as more in the evenings and weekends, than those employed by an organization. Even though being able to decide when to do one's work may be a sign of flexibili…
La vulgarisation scientifique et les doctorants : mesure de l'engagement, exploration d'effets sur le chercheur
2018
We ask two questions: what are the factors that influence researchers’ public engagement activities (PEA)? And what are the impacts of these activities on the researcher? After presenting a historical overview of PEA, we analyze 20 surveys carried out between 1967 and 2014. We identify some global trends: PEA is generally positively perceived, researcher’s engagement is occasional but robust. Besides those trends some differences appear between studies based on theoretical models and empirical studies: the latter report complaints such as lack of time or lack of recognition, whereas theoretical-based ones challenge these statements.To further explore our two questions, we used two approache…
Enhanced flexible algorithm for the optimization of slot filling factors in electrical machines †
2020
The continuous development in the field of industrial automation and electric mobility has led to the need for more efficient electrical machines with a high power density. The improvement of electrical machines’ slot filling factors is one of the measures to satisfy these requirements. In recent years, this topic has aroused greater interest in the industrial sector, since the evolution of the winding technological manufacturing processes allows an economically sustainable realization of ordered winding arrangements, rather than random ones. Moreover, the manufacture of electrical machines’ windings must be preceded by an accurate design phase in which it is possible to evaluate the maximu…
Attention and Planning in Older Adults
1997
In a study with 48 adults between 65 and 97 years of age, we examined the influence of working memory, inhibitory efficiency, and attentional flexibility on the ability to solve efficiently a complex planning task: 26 of the subjects were living independently in their own home, and 22 subjects were recruited from nursing homes. Subjects first participated in a number of cognitive ability tests. They then had to plan a trip for a group of 20 people. The results indicate that inhibitory efficiency combined with the flexible use of attentional resources can account for substantial amounts of variance in the planning task. The results support the view that chronological age does not necessaril…
On the importance of being flexible: early interrelations between affective flexibility, executive functions and anxiety symptoms in preschoolers
2020
When children are confronted with an emotional problem, affective flexibility mobilizes their cognitive and emotional resources to optimally address it. We investigated the contribution of executiv...
Individual and combined effects of disturbance and N addition on understorey vegetation in a subarctic mountain birch forest
2011
Questions: What are the effects of repeated disturbance and N-fertilization on plant community structure in a mountain birch forest? What is the role of enhanced nutrient availability in recovery of understorey vegetation after repeated disturbance? How are responses of soil micro-organisms to disturbance and N-fertilization reflected in nutrient allocation patterns and recovery of understorey vegetation after disturbance? Location: Subarctic mountain birch forest, Finland. Methods: We conducted a fully factorial experiment with annual treatments of disturbance (two levels) and N-fertilization (four levels) during 1998‐2002. We monitored treatment effects on above-ground plant biomass, plan…
