Los estilos de liderazgo de la Policía Local de la Comunidad Valenciana: Una aproximación desde la Teoría del Liderazgo Transformacional

2012

Tomando como base la Teoría de Liderazgo Transformacional (Bass, 1985), se estudian las conductas que componen los estilos de liderazgo y su relación con tres variables de resultado: la eficacia del líder, la satisfacción con el líder y el esfuerzo extra de los subordinados; así como el aumento de los efectos (augmentation effect) del liderazgo transaccional cuando además se utiliza el liderazgo transformacional. La muestra es representativa del universo de policías locales de la Comunidad Valenciana (España) y está compuesta por 975 policías locales (828 hombres y 147 mujeres) pertenecientes a las plantillas de 42 localidades y que son dirigidos por 42 jefes. Los resultados muestran jefes …

Compromiso afectivo, liderazgo participativo e innovación del empleado: una investigación multinivel

2019

ABSTRACT Research investigating the relationship between organizational affective commitment and employee innovation has yielded scarce and inconsistent findings. This study examined the role of participative leadership in a team as a boundary condition of the effectiveness of organizational affective commitment predicting employee innovation. Data were collected from 343 employees in 34 teams from different Italian companies. The results from hierarchical linear modelling analysis indicated that the relationship between organizational affective commitment and employee innovation was stronger when team-level participative leadership was high. Our findings provide meaningful insights regardi…

Tiratricol neutralizes bacterial endotoxins and reduces lipopolysaccharide-induced TNF-alpha production in the cell.

2008

Contains fulltext : 70610.pdf (Publisher’s version ) (Closed access) The screening of a commercially available library of compounds has proved a successful strategy for the identification of a lead compound in a drug discovery programme. Here, we analysed 880 off-patent drugs, which initially comprised the Prestwick Chemical library, as sources of bacterial endotoxin neutralizers. We identified 3,3',5-triiodo-thyroacetic acid (tiratricol) as a non-antibacterial compound that neutralizes the toxic lipopolysaccharide.

StellaTUM: current consensus and discussion on pancreatic stellate cell research

2011

The field of pancreatic stellate cell (PSC) biology is very young, as the essential in-vitro tools to study these cells (ie, methods to isolate and culture PSC) were only developed as recently as in 1998. Nonetheless, there has been an exponential increase in research output in this field over the past decade, with numerous research groups around the world focusing their energies into elucidating the biology and function of these cells. It is now well established that PSC are responsible for producing the stromal reaction (fibrosis) of two major diseases of the pancreas—chronic pancreatitis and pancreatic cancer. Despite exponentially increasing data, the methods for studying PSC remain var…

The power of empowering team leadership over time: A multi-wave longitudinal study in nuclear power plants

2021

Abstract Team attitudes in critical infrastructures are essential to achieving reliable operations despite internal and external challenges, and empowering team leadership (ETL) may be an important precursor of these attitudes. The present study aimed to test whether ETL was related to teams’ satisfaction trajectories, measured as changes in job satisfaction and safety satisfaction at three time points. Hypotheses were tested in a sample of 48 teams from two Spanish nuclear facilities in three different waves (2008, 2011, and 2014). Growth Modeling using hierarchical linear models with SPSS 20.0 revealed that ETL was positively related to initial levels of teams’ job and safety satisfaction…

A Revised Short Form of the Extended Class Play Among Italian Early Adolescents

2019

Among the measures assessing peer reputation, the Extended Class Play (ECP) is now used extensively in North American settings. Little information is available in other cultural contexts. Furthermore, practical considerations suggest developing a shorter form of the ECP to be used in socio-educational environments. This study examined the ECP dimensions of peer assessment in Italy as well as developed a shorter form of the measure. We revised the ECP using factor analyses according to an explorative-confirmatory approach. The original 37-item ECP was shortened to a 22-item version and, subsequently, the properties of the revised measure were evaluated. We performed two studies comprising, r…

Potential Antioxidant Activity of Calcium and Selected Oxidative Stress Markers in Lead- and Cadmium-Exposed Workers

2020

Occupational lead (Pb) and cadmium (Cd) exposure occurs during processing and casting of nonferrous metals such as zinc. In contrast to Pb and Cd, Ca is essential for living organisms due to its important role in a multitude of functions, from cell signaling to bone growth. Pb and Cd exposure affects calcium metabolism in various ways. The aim of this study was to investigate the blood levels of Pb, Cd, and Ca and the levels of selected oxidative stress biomarkers in workers exposed to Pb and Cd. Population groups included 264 male employees in a lead-zinc smelter. The study population was divided into two subgroups based on the median of Ca serum level (2.42 mmol/l): the low-Ca-level group…
