La incidencia del salario mínimo interprofesional en sectores de bajos salarios
2012
El salario mínimo es un tema que ha vuelto a cobrar actualidad. La mayoría de los análisis que se realizan al respecto se centran en determinar si su nivel tiene algún tipo de incidencia sobre el empleo. No obstante, son escasos los trabajos que abordan si efectivamente el salario mínimo cumple con su objetivo básico: mejorar las rentas de los perceptores de bajos salarios. En este trabajo abordamos precisamente esta cuestión. Para ello se analiza la evolución de los salarios en la negociación colectiva en tres sectores considerados de bajos salarios (comercio al por menor, hostelería y limpieza de locales y edificios), centrándonos en los puestos inferiores de la escala salarial. The minim…
Sport as a vehicle for implementing corporate social responsibility: firms listed on the Warsaw and Moscow stock exchanges
2021
This paper provides a descriptive account of the extent to which firms listed on the Warsaw (WSE) and Moscow (MSE) Stock Exchanges use sport for their corporate social responsibility agendas. Drawing on institutional isomorphism, we deductively categorised CSR through sport cases based on the framework developed by Bason and Anagnostopoulos (2015). A total of 1317 documents were content-analysed, 442 from WSE firms and 875 from MSE firms. A total of 2501 CSR-through-sport initiatives were reported over the five-year period studied (2013-2017) in the WSE case and 2175 in the MSE case. Our results show that internationally listed firms are increasingly embracing sport for their CSR programs, …
The role of task-related antecedents for the development of turnover intentions in temporary project teams
2016
AbstractHigh turnover can cause serious problems in organizations. Yet, previous research confirmed that HRM practices are useful to influence the development of turnover intentions. Existing studies have revealed a variety of factors that drive individuals to leave permanent organizations (POs) but almost no research has considered turnover in temporary organizations (TOs). Yet, TOs, such as project teams, have become increasingly prevalent and exhibit several characteristics that are distinct from POs. Hence, the antecedents of turnover intentions in TOs may also differ from those in POs. However, empirical evidence for this proposition is still lacking. In order to address this research …
Rule Enactment in a Pan-European Labour Market: Transnational Posted Work in the German Construction Sector
2014
This article analyses the micro-level rule enactment of the posting of workers framework in the German construction sector. I examine how actors draw on different power resources in order to influence policies without formal negotiation within transnational workspaces and thereby initiate institutional change. Drawing on interviews with posted workers, managers, unionists, works councillors and labour inspectors I show how transnational subcontracting allows the emergence of different regulatory spaces at national and workplace level. The article concludes that the informal renegotiation of employment relations in transnational workspaces is likely to destabilize the posting framework negot…
Investigating the links between resilience, perceived HRM practices, and retirement intentions
2019
Purpose Human resource management (HRM) scholars’ interest in older employees’ resilience has only recently started to emerge. Little is known about how resilience and perceived HRM are linked to different retirement intentions. Drawing on the conservation of resources and social exchange theories, the purpose of this paper is to investigate the links between perceived HRM practices, resilience and retirement intentions. Additionally, the paper examines the possible mediating role of resilience in the relationship between perceived HRM practices and retirement intentions. Design/methodology/approach In 2016, a cross-sectional study was conducted among older (50+) nursing professionals work…
The Determination of Carbohydrates by High-Performance Anion-Exchange Chromatography Coupled with Pulsed Amperometric Detection (HPAEC-PAD)
2021
Chromatography techniques are widely used to separate, identify, and quantify molecules depending on their physicochemical properties. Standard methods range from simple size exclusion to separation based on affinity or ion exchange. Here, we present a method for the direct analysis of carbohydrates in Magnaporthe oryzae using high-performance anion-exchange chromatography (HPAEC) coupled with pulsed amperometric detection (PAD). The combination of HPAEC with PAD provides the highest selectivity and sensitivity with minimal sample preparation and cleanup time. Utilizing our HPAEC-PAD approach, we obtain reliable and highly reproducible determination of carbohydrates produced as osmotic stre…
Ecosystem services mapping and assessment for policy- and decision-making : Lessons learned from a comparative analysis of European case studies
2020
This paper analyses and compares a set of case studies on ecosystem services (ES) mapping and assessment with the purpose of formulating lessons learned and recommendations. Fourteen case studies were selected during the EU Horizon 2020 “Coordination and Support Action” ESMERALDA to represent different policy- and decision-making processes throughout the European Union, across a wide range of themes, biomes and scales. The analysis is based on a framework that addresses the key steps of an ES mapping and assessment process, namely policy questions, stakeholder identification and involvement, application of mapping and assessment methods, dissemination and communication and implementation. T…
The Effect of Overeducation on Job Content Innovation and Career-Enhancing Strategies Among Young Spanish Employees
2009
The increase of education in younger people and the relative scarcity of qualified jobs available for them make the overeducation of young workers a social issue. We explored the relationships between overeducation and extra-role behaviors (job content innovation and career-enhancing strategies) as well as the direct and moderating role of personal initiative and intrinsic work values in these relationships. We collected data from a sample of 638 young Spanish employees. As expected, there were negative relationships between overeducation and content innovation and career-enhancing strategies. Personal initiative and intrinsic work values related positively to extra-role behaviors. Moreove…
Multiple activation pathways of benzene leading to products with varying genotoxic characteristics.
1989
Abstract Benzene and 13 potential metabolites were investigated for genotoxicity in Salmonella typhimurium and V79 Chinese hamster cells. In the presence of NADPH-fortified hepatic postmitochondrial fraction (S9 mix), benzene reverted his- S. typhimurium strains. The effect was strongest in strain TA1535. Among the potential metabolites, only the trans-1,2-dihydrodiol, in the presence of S9 mix, and the diol epoxides, in the presence and absence of S9 mix, proved mutagenic in this strain. The anti-diol epoxide was more potent than the syn-diastereomer. Both enantiomers of the anti-diastereomer showed similar activities. S9 mix did not appreciably affect the mutagenicity of the anti-diol epo…
Hybrid magnetic materials based on layered double hydroxides: from the chemistry towards the applications
2014
Layered double hydroxides (LDHs) are the leitmotiv of this dissertation. Contradicting the assertion that “any past was better”, LDHs have been continuously revisited from the middle of the twentieth century, and represent an excellent example of the never-ending beauty of Chemistry. New synthetic perspectives are giving a new impetus to LDH chemistry, which among hybrid materials, are finding their heyday. This is resulting in novel materials and also paving the way for new fundamental and practical insights. This dissertation is focused on magnetic LDHs, and for the sake of clarity it is organized in three main parts: we will move from basic synthetic and physical aspects of LDHs, through…
