The Ranking of the Regions With Regard to Their Sports Facilities to Improve Their Planning in Sport: The Case of Spain

Sports facility planning by the public authorities should be considered to be one of the main policies to have an indirect influence on the aim of ensuring a healthy population, as well as reducing its physical inactivity. Our research aims to study and compare the state of sports infrastructures in the regions of Spain, using a synthetic indicators. Our results should serve not only to detect the vast imparity between different regions, which has come about because of varying investment and management with regard to sports infrastructures, but also to redirect building planning and sports management policies onto the right path, and also give food for thought.     

The Decent Work Questionnaire: Development and validation in two samples of knowledge workers

This research develops a Decent Work Questionnaire (DWQ) to measure workers’ perceptions of decent work. Current measurements of decent work are almost completely lacking at the individual worker level of analysis, and this study contributes to filling the gap. The authors designed their DWQ based on the substantive elements used by the ILO in its Decent Work Agenda, with the final 31‐item version of the DWQ yielding seven factors related to decent work. Showing good reliability coefficient values and good convergent and discriminant validity, this DWQ could open up new avenues for empirical studies on the concept of decent work.     

Unions,Firing Costs,and Unemployment

Abstract. We study the effects of firing costs in unionized economies with heterogeneous workers. We consider an overlapping generations model where workers participate in the labour market both when young and when old. All workers belong to the same union that sets wages unilaterally. We find that at given wages firing costs increase youth unemployment and decrease old‐age unemployment. However, once the wage response is considered, firing costs increase both youth and old‐age unemployment. Indeed, knowing that when firing costs are higher firms refrain from firing, the union increases the wage of old workers, and, therefore, old‐age unemployment increases.     

The Impact of Body Dissatisfaction on Distressing Sexual Difficulties Among Men and Women: the Mediator Role of Cognitive Distraction

Research has demonstrated a negative impact of cognitive distraction on sexual activity, and body dissatisfaction has been associated with less satisfying and fewer sexual activities. In the current study we examined the extent to which cognitive distraction, based on body appearance and sexual performance, mediated the impact of body dissatisfaction on sexual difficulties among women and men. A sample of 493 women (M_age = 30.61) and 595 men (M_age = 37.90) completed an online survey. Women reported significantly higher levels of distressing sexual difficulties, significantly more body dissatisfaction, and greater cognitive distraction based on appearance than men. In contrast, men reported higher cognitive distraction based on performance than women. A path analysis model indicated that, for men, only cognitive distraction based on performance mediated the effects of body dissatisfaction on distressing sexual difficulties, and the mediation was only partial as body dissatisfaction had a significant direct effect on distressing sexual difficulties. In contrast, among women, both appearance-based cognitive distraction and performance-based cognitive distraction fully mediated the effects of body dissatisfaction on distressing sexual difficulties.     

Should I stay or should I go? Educational choices and earnings: An empirical study for Portugal

We analyse educational choices and earnings of individuals at two different levels in the Portuguese educational system. At each exit we consider two decisions: the decision to continue studying and the employment decision. We find empirical support for the existence of selectivity bias as the errors of the earnings functions are in general correlated with the disturbances of the decision functions. The obtained rates of return to education vary between 2.4 and 9.4 percent, depending on whether or not selectivity and quantity effects are excluded from the computations. Note that selectivity represents three quarters of this difference. Received: 5 March 2001/Accepted: 10 October 2001 I am grateful for the comments of the editor and two anonymous referees.

Estimation of cost allocation coefficients at the farm level using an entropy approach

This paper aims to estimate the farm cost allocation coefficients from whole-farm input costs. An entropy approach was developed under a Tobit formulation and was applied to a sample of farms from the 2004 Farm Accountancy Data Network data base for Alentejo region, Southern Portugal. A Generalized Maximum Entropy model and Cross Generalized Entropy model were developed to the sample conditions and were tested. Model results were assessed in terms of their precision and estimation power and were compared with the observed data. The entropy approach showed to be a flexible and valid tool to estimate incomplete information, namely regarding farm costs.     

Sing for me,Mama! Infants' discrimination of novel vowels in song

When adults speak or sing with infants, they sound differently than in adult communication. Infant-directed (ID) communication helps caregivers to regulate infants' emotions and helps infants to process speech information, at least from ID-speech. However, it is largely unclear whether infants might also process speech information presented in ID-singing. Therefore, we examined whether infants discriminate vowels in ID-singing, as well as potential differences with ID-speech. Using an alternating trial preference procedure, infants aged 4–6 and 8–10 months were tested on their discrimination of an unfamiliar non-native vowel contrast presented in ID-like speech and singing. Relying on models of early speech sound perception, we expected that infants in their first half year of life would discriminate the vowels, in contrast to older infants whose non-native sound perception should deteriorate, at least in ID-like speech. Our results showed that infants of both age groups were able to discriminate the vowels in ID-like singing, while only the younger group discriminated the vowels in ID-like speech. These results show that infants process speech sound information in song from early on. They also hint at diverging perceptual or attentional mechanisms guiding infants' sound processing in ID-speech versus ID-singing toward the end of the first year of life.     

Élaboration et validation d'un questionnaire sur le travail décent

Les auteurs cherchent à élaborer un outil de mesure du travail décent reposant sur un questionnaire inédit axé sur les perceptions des travailleurs. Les items proposés se fondent sur les «éléments fondamentaux» du travail décent selon l'OIT. Une première version de soixante‐douze items est administrée sur deux grands échantillons au Portugal et au Brésil. Les analyses factorielles exploratoire et confirmatoire menées sur cette base permettent d'isoler sept facteurs spécifiques et un facteur global du travail décent. Avec de bons coefficients de fiabilité et une bonne validité convergente et discriminante, le questionnaire proposé ouvre la voie à de nouvelles études empiriques dans le domaine.     

International NGOs and the Guatemalan Peace Accords

This paper looks at the impact of the Guatemalan Peace Accords of 1996 on the work of International Non-Governmental Organizations (INGOs). In particular, the paper focuses on changes in INGO organizational structure, programming priorities, and relationships with the Government of Guatemala and local counterparts between 1993 and 2000. It is shown that the peacetime atmosphere has vastly improved INGO capacity to work in Guatemala, and that continued success depends on INGO adaptation to the new opening, governmental commitment to the Peace Accords, and increased INGO willingness to cooperate on large-scale, integrated projects.     

Requiring Connectivity in the Set Covering Problem

Given a bipartite graph with bipartition V and W, a cover is a subset C V such that each node of W is adjacent to at least one node in C. The set covering problem seeks a minimum cardinality cover. Set covering has many practical applications. In the context of reserve selection for conservation of species, V is a set of candidate sites from a reserve network, W is the set of species to be protected, and the edges describe which species are represented in each site. Some covers however may assume spatial configurations which are not adequate for conservational purposes. Indeed, for sustainability reasons the fragmentation of existing natural habitats should be avoided, since this is recognized as being disruptive to the species adapted to the habitats. Thus, connectivity appears to be an important issue for protection of biological diversity. We therefore consider along with the bipartite graph, a graph G with node set V, describing the adjacencies of the elements of V, and we look for those covers C V for which the subgraph of G induced by C is connected. We call such covers connected covers. In this paper we introduce and study some valid inequalities for the convex hull of the set of incidence vectors of connected covers.MSC2000: 90C10, 90C57This authors research was financially supported by the Portuguese Foundation for Science and Technology (FCT).This paper is part of this authors Ph.D. research.
