Associations between self-perceived and desired health-related physical fitness in Spanish children

Health-related physical fitness (HRPF) has emerged as an important marker of health among children. It is usually defined as a multidimensional construct consisting of cardiorespiratory endurance; muscular strength and endurance; and flexibility. Currently, health policies are aimed at getting children to increase their HRPF levels. Understanding the relationship between the perceived and the desired levels of fitness can be important to avoid the abandoning of physical activity practice. We analyzed the associations between the self-perceived and the desired health-related physical fitness. A modified version of the self-perceived HRPF questionnaire was completed by 330 children (148 girls, mean age: 10.78 ± 0.67 years, and 182 boys, mean age: 10.82 ± 0.61 years). Fitness was measured through tests selected from the Eurofit battery. The questions regarding desired HRPF showed moderate internal consistency (Cronbach’s α: 0.671) and good test–retest reliability (ICC: 0.761). In general, children shared a desire to improve their self-perceived HRPF. Those who perceived themselves as already being fit were the ones who showed the strongest desire for achieving higher HRPF levels

¿Es discriminatorio el reparto de cuotas de pesca en la UE? Un caso de estudio

El objetivo de este trabajo es aportar información que nos permita argumentar mejor sobre las cualidades económicos del mecanismo automático de asignación utilizado en el seno de la Unión Europeo para repartir los TACs de las diferentes especies y en las distintos zonas en cuotas de pesco nacionales. A través de un sencillo ejemplo, utilizando datos de siete segmentos de floto comunitarios, observamos que tal reparto no parece ser un instrumento económicamente neutral, pues puede favorecer la permanencia en la actividad de floto menos eficientes y con mayores necesidades de financiación comunitaria, o de flotas con menor capacidad generadora de renta y empleo

Pareto optimality in continuous-time OLG economies

The aim of this paper is the achievement of a complete characterization of the Pareto optimality of competitive equilibria for deterministic, pure exchange, continuous-time economies with a countable number of overlapping generations, where each consumer's life-span consists in a bounded interval of time. For such an environment, we obtain separate sufficient and necessary conditions for Pareto optimality in the form of the Cass' criterion, that is, in terms of the equilibrium prices. However, these conditions are not equivalent in general. Therefore, in order to get that equivalence we are compelled to impose certain restrictions, either on consumers' lifetimes, assuming that all of them have the same longevity, or on the dynamic behaviour of relative intertemporal equilibrium prices. In both cases, we are able to derive a single condition that is sufficient and necessary for efficiency, thus achieving full characterizations.

By means of a simple example, using data of seven EU fleet segments, we observe that such allocation mechanism seems not to be a neutral tool from a economic point of view, since it may favour the maintenance in actitivy of either less efficient fleets and with greater community financing needs, or fleets with less capacity to create rent and employment
