Problems of the Polish labour market against the backgrounds of the EU countries after 2004
2011
The situation in the labour market in the contemporary world is the subject of continual surveys and analyses. Particular attention in those surveys is focused on unemployment continuing over long-time that occurs despite governments of the majority of countries undertaking continual efforts aiming at liquidating or at least limiting it. The main goal of the paper is to present the current problems of the labour market in Poland and other European Union countries that developed under the influence of the global economic crisis. An attempt at presenting the current situation and selected characteristics of the labour market in Poland developed under the influence of the conditions existing a…
La evaluación en Formación Profesional como mejora del proceso enseñanza aprendizaje en la resolución de problemas
2016
Desde nuestra perspectiva profesional concebimos la evaluación como una acción inherente y simultánea al quehacer educativo que posibilita la toma de decisiones para mejorar el rendimiento y la comprensión del alumnado sobre lo que se hace en las aulas de Formación Profesional y cómo se hace. Esta experiencia se contextualiza en el Ciclo Formativo de Grado Superior “Gestión Comercial y Marketing". El proceso de evaluación del proyecto resolución de problemas sobre gestión de stocks se desarrolla en tres momentos: evaluación diagnóstica/inicial, evaluación durante el proceso y evaluación final. Los docentes pretendemos implicar al alumnado de la asignatura Logística Comercial en los procedim…
Global collaborative networks on meta-analyses of randomized trials published in high impact factor medical journals: a social network analysis
2014
Abstract Background Research collaboration contributes to the advancement of knowledge by exploiting the results of scientific efforts more efficiently, but the global patterns of collaboration on meta-analysis are unknown. The purpose of this research was to describe and characterize the global collaborative patterns in meta-analyses of randomized trials published in high impact factor medical journals over the past three decades. Methods This was a cross-sectional, social network analysis. We searched PubMed for relevant meta-analyses of randomized trials published up to December 2012. We selected meta-analyses (including at least randomized trials as primary evidence source) published in…
Experimental increase of worker diversity benefits brood production in ants
2021
Background The reproductive division of labor of eusocial insects, whereby one or several queens monopolize reproduction, evolved in a context of high genetic relatedness. However, many extant eusocial species have developed strategies that decrease genetic relatedness in their colonies, suggesting some benefits of the increased diversity. Multiple studies support this hypothesis by showing positive correlations between genetic diversity and colony fitness, as well as finding effects of experimental manipulations of diversity on colony performance. However, alternative explanations could account for most of these reports, and the benefits of diversity on performance in eusocial insects stil…

Indemnización y trabajador en excedencia afectado en expediente de regulación de empleo
2021
espanolEn este trabajo se realiza un analisis de los derechos del trabajador en excedencia voluntaria que se encuentra afectado en un expediente de regulacion de empleo, concretamente, del derecho a recibir la correspondiente indemnizacion por despido colectivo o no. La doctrina judicial y jurisprudencial ha negado que el trabajador excedente incurso en un expediente de regulacion de empleo tenga derecho a la misma. No obstante, ello va unido a la posicion que se tenga sobre la naturaleza juridica de la excedencia voluntaria, aspecto debatido entre la doctrina, tanto cientifica como judicial. En este sentido, una linea doctrinal ha considerado que la excedencia voluntaria tiene un caracter …
A gesture recognition framework for exploring museum exhibitions
2018
In this paper we present a gesture recognition framework for providing the visitors of a museum exhibition with a non intrusive interface for the multimedia enjoyment of digital contents. Early experiments were carried out at the Computer History Museum Exhibition of the University of Palermo.
FISH: Face Intensity-Shape Histogram representation for automatic face splicing detection
2019
Abstract Tampered images spread nowadays over any visual media influencing our judgement in many aspects of our life. This is particularly critical for face splicing manipulations, where recognizable identities are put out of context. To contrast these activities on a large scale, automatic detectors are required. In this paper, we present a novel method for automatic face splicing detection, based on computer vision, that exploits inconsistencies in the lighting environment estimated from different faces in the scene. Differently from previous approaches, we do not rely on an ideal mathematical model of the lighting environment. Instead, our solution, built upon the concept of histogram-ba…
Evaluating the impact of friends in predicting user’s availability in online social networks
2017
In recent years, Online Social Networks (OSNs) have changed the way people connect and interact with each other. Indeed, most people have registered an account on some popular OSNs (such as Facebook, or Google+) which is used to access the system at different times of the days, depending on their life and habits. In this context, understanding how users connect to the OSNs is of paramount importance for both the protection of their privacy and the OSN’s provider (or third-party applications) that want to exploit this information. In this paper, we study the task of predicting the availability status (online/offline) of the OSNs’ users by exploiting the availability information of their frie…
Performance of LoRa for Bike-Sharing Systems
2019
Today bike sharing systems are becoming popular in many cities as short-distance transit vehicles. More than 18 million bicycles are available worldwide for public use and one of the main problems that afflicts such sharing systems is the loss of bikes, which can be stolen or simply left in unknown locations. Thus, many bikes are docked or tracked using GPS and costly cellular connections. In this paper, we consider the emerging Long Range (LoRa) technology for use in bike sharing systems. LoRa exploits free ISM bands and has been conceived for low power and low data rate applications. Additionally, LoRa is characterized by large cells and heterogeneous application domains, which may lead t…
