Union representation and prevention of occupational risks during the crisis: impact and limits

2019

La investigación que presentamos estudia el impacto de la intervención sindical en materia de salud laboral, en lo que se refiere tanto a la gestión preventiva y creación de una cultura participativa como en los procesos de vigilancia y control de las condiciones de trabajo. A tal efecto, se han consultado las principales encuestas nacionales e internacionales sobre gestión de riesgos laborales en las empresas, analizando los datos más relevantes en base a modelos de regresión logística y lineal, lo que ha permitido constatar que la representación sindical de los trabajadores en la empresa (generalista y especializada) correlaciona positivamente con el desarrollo de las principales dimensio…

Los Derechos Humanos en la Filosofía Analítica: Ronald Dworkin

2013

Este artículo atiende la manera en que Ronald Dworkin –como H. L. A. Hart y John Rawls, a quienes él sigue– enuncia el fundamento de los derechos humanos. Cierta presencia de iusnaturalismo en ese fundamento es señalado por Dworkin, Hart y Rawls y ellos buscan cuáles serían los derechos naturales del hombre (uno de ellos dice que sería la libertad y los otros dos dicen que sería la igualdad), i.e., ellos son derechos que no pueden depender de un contrato social porque ellos son primeros para estos y son presupuestos; debido a esto, ellos no pueden depender de la sola positivación. Hay, entonces, un iusnaturalismo escondido o latente en el fundamento de los derechos humanos como derechos mor…

Fixed point results for α-implicit contractions with application to integral equations

2016

Recently, Aydi et al. [On fixed point results for α-implicit contractions in quasi-metric spaces and consequences, Nonlinear Anal. Model. Control, 21(1):40–56, 2016] proved some fixed point results involving α-implicit contractive conditions in quasi-b-metric spaces. In this paper we extend and improve these results and derive some new fixed point theorems for implicit contractions in ordered quasi-b-metric spaces. Moreover, some examples and an application to integral equations are given here to illustrate the usability of the obtained results.

Il contratto a termine nelle fondazioni liriche

2020

The discipline of the fixed term contracts in opera foundations has been repeatedly modified in the last years. The attempts of the legislator to avoid the application of ordinary rules to these subjects has been nullified by the European Court of Justice. It has been therefore introduced a new regulation, that applies to these contracts some of the limits provided for in EU Directive 1999/70, but not the sanction of the conversion of the fixed term contract into a contract of indeterminate duration, in case of violation of the above mentioned limits. The workers have rights only to a monetary compensation, that can be considered an effective protection to unlawful use of flexible contracts.

Comparison of social-ecological resilience between two grassland management patterns driven by grassland land contract policy in the Maqu, Qinghai-Ti…

2018

Embraced for decision-making, resilience has evolved as a meaningful term in areas such as ecology, the economy and society. After a policy of grassland contracts was implemented on the Qinghai-Tibetan Plateau, two grassland management patterns evolved: the multi-household management pattern (MMP) and the single-household management pattern (SMP). Within a resilience-driven perspective, this study compared the outcomes of these grassland management patterns by measuring their effects on the resilience of grazing, ecological, economic and social systems. Resilience indicators for each of the four systems were: grazing system (grazing space, transhumance, water source and reproduction); ecolo…

: Quantification of the morphological evolution of the Hominid skull and heterochronies

1998

Comparisons of adult skulls of various species of great apes, fossil hominids and modem humans in the sagittal, Francfort and ortho-sagittal planes reveal a series of three separate organisation plans: 'GreatApe', 'Australopithecine'and 'Homo', tbe latter including primitive men (Homo ergaster-erectus-neandertalensis) and modern humans (Homo sapiens). Morphological changes between these plans are quantified for the first time here by vector fields. This study confirms the existence of cranio-facial contraction, which occurs as a series of leaps. The juvenile morphology of the great ape skull is broadly preserved in adult Homo sapiens, suggesting that numerous heterochronies have occurred in…

Brevi considerazioni su Paul. 32 ad ed. D.19.4.1.4: tra tradizione testuale e proposte emendative

2012

This paper analyses a famous excerpt from the roman jurist Paulus on the barter (Paul. 32 ad ed. D.19.4.1.4). According to the scholars this passage lists (even if confusedly) the available procedural remedies against the defaulting party, given the institution of a valid contract: action in id quod interest, aimed at obtaining a specific performance, and the condictio quasi re non secuta, for the recovery of what has already been given. However, this reconstruction does not consider the connection (igitur) with the previous § 3, in which it is affirmed that barter is void when a party delivers a third party property. So the author suggests to abandon Mommsen’s reconstruction based on Bas.2…

Effects of magnesium chloride on the contractile response of uterus to several agonists in Ca-free solution

1987

Abstract The effects of MgCl2 on the oestrogen-dominated rat uterus have been examined. Tissues were preincubated in a Ca2+- and Mg2+-free medium containing 3 mM EDTA. Most experiments were subsequently performed in a similar medium containing either no EDTA or EDTA (1 mM). When MgCl2 was added cumulatively (1–32 mM) no contractile responses were obtained in Ca,Mg-free medium or in Ca,Mg-free high K+ solution. When 2 mM CaCl2 as added, a sustained contraction was obtained. Subsequent addition of cumulative concentrations of MgCl2 caused concentration-dependent relaxation. Oxytocin, 2 μM, produced a small and sustained contraction in a Ca,Mg-free medium. Addition of MgCl2, 2 mM, increased th…
