Análisis de los factores que influyen en el proceso de creación de una cooperativa de trabajo asociado.

Este trabajo pretende contribuir al conocimiento existente sobre el proceso de creación de cooperativas de trabajo asociado (CTA) a partir de la aplicación de un método inductivo-deductivo como es la Teoría Fundamentada. Para ello se han realizado un total de 37 entrevistas en profundidad con los socios-promotores de CTA creadas en el periodo 2001-2002, todas ellas localizadas en la Comunidad Valenciana (España). Como resultado de la aplicación de la metodología se han identificado un total de 29 códigos substantivos o factores que influyen en el comportamiento de los socios fundadores en cada una de las fases del proceso de creación de la empresa.This paper aims to contribute to existing knowledge related to the worker cooperative (CTA) creation process by studying the factors that influence the process using an inductive-deductive method: the Grounded Theory. For this reason, a total of 37 in-depth interviews have been carried out with the founding members of worker cooperatives set up within the period of 2001-2002, all of which are located in the Valencian Community (Spain). As a consequence of the application of the methodology, we have identified a total of 29 codes or factors that influence the behaviour of the founding members in each of the stages involved in the process of the creation of [email protected]

Recursos de información ambiental en Internet

Resources of environmental information in Internet. The shortage in Spain of libraries and specialized centers of documentation in environmental subjects could partly be replaced by the consultation the services available in Internet. Within this context it is essential to consider network Internet, since, due to the growth that has experimented, it supposes excellent informative means. It offers new forms of access to the information that cannot be ignored, because they constitute at the present time the way fastest and economic to have a great volume of international information with diverse formats derived from the type on watch in which they are integrated

Timber Buildings: A Sustainable Construction Alternative

[EN] The construction and building environment is one of the largest contributors to climate change, greenhouse gas emissions, depletion of natural resources and damage to ecological integrity. Therefore, the use of more sustainable materials in construction is currently of great interest. Structural wood is considered as a versatile renewable material, having an optimal strength-to-weight ratio, insulating properties, low carbon emissions in the operational life cycle and a great abundance in nature. Furthermore, unlike other materials, wood is the only one that stores carbon in its production. The purpose of this project is to evaluate, through the Life Cycle Analysis methodology, the environmental impact of the construction of buildings made of timber compared to reinforced concrete buildings, understanding the environmental benefits and disadvantages of each technology. The results obtained from the comparison of a timber building with its concrete counterpart confirm the feasible benefit of wood in the reduction of carbon emissions and non-renewable energy consumption, as well as other positive aspects such as the reduction of other emissions. By highlighting the benefits and opportunities of wood it is intended to promote the material in construction and the development of more efficient buildings.Nuñez Avila, JD.; Blanca Giménez, V.

B-parameters of the complete set of matrix elements of (Delta B = 2) operators from the lattice

We compute on the lattice the ``bag'' parameters of the five (Delta B = 2) operators of the supersymmetric basis, by combining their values determined in full QCD and in the static limit of HQET. The extrapolation of the QCD results from the accessible heavy-light meson masses to the B-meson mass is constrained by the static result. The matching of the corresponding results in HQET and in QCD is for the first time made at NLO accuracy in the MSbar(NDR) renormalization scheme. All results are obtained in the quenched approximation.Comment: 27 pages (5 figures

El gobierno de Zaragoza y sus hombres tras la Nueva Planta: los corregidores-intendentes

--The Nueva Planta regimen was slowly and doubtfully applied in the aragonese territories. The establishment of corregimientos was not accomplished before 1718 when they were bound to the intendencies. The process and the eleven corregidor-intendant's profiles are shown in this study.La aplicación del régimen de Nueva Planta en los territorios aragoneses fue un proceso lento y dubitativo. El establecimiento de corregimientos no culminó hasta 1718, con su vinculación a la intendencia. El articulo estudia este proceso y muestra el perfil de los once individuos que ocuparon el cargo de corregidor-intendente

Measurements of OH* and CH* Chemiluminescence in Premixed Flames in a Constant Volume Combustion Bomb under Autoignition Conditions

The objectives of this paper are as follows: (1) To study parametrically OH* and CH* chemiluminescence trace evolution as a function of the initial pressure, temperature, and equivalence ratio of premixed flames of n-heptane, under autoignition conditions, in a constant volume combustion bomb. The signals of the electronically excited states of OH* (306 nm) and CH* (430 nm) have been detected through band-pass filters with two photomultiplier tubes placed in an optical access of the combustion bomb. (2) To determine the feasibility of using OH* and CH* chemiluminescence signals as active-control parameters for premixed flames. For this purpose, a correlation between OH* chemiluminescence emissions and the equivalence ratio and the rate of heat release during the combustion process is obtained, as well as a correlation between CH* chemiluminescence emissions and the adiabatic flame temperature. (3) To investigate the relationship between the OH* and CH* chemiluminescent emissions in premixed combustions of n-heptane, iso-octane, and a mixture of 50% n-heptane and 50% toluene and the equivalence fuel/air ratio for a given initial temperature and pressure. To reach these objectives, measurements of OH* and CH* chemiluminescences from premixed flames of n-heptane with autoignition are reported at equivalence ratios ranging from 0.8 to 1.0, in a constant volume combustion bomb. The morphology of the curves and the relationships with parameters of interest during the combustion process (i.e., the rate of heat release, burned temperature, etc.) are studied. In addition, premixed combustions of iso-octane, n-heptane, and a mixture of n-heptane and toluene are also investigated at different fuel/air equivalence ratios for a given initial pressure and temperature, to assess the possibility of using the ratio between the OH* and CH* chemiluminescence signals to monitorize the equivalence ratio during the combustion, as other authors have considered previously. © 2010 American Chemical Society.The authors of this paper thank the Spanish Ministry of Science and Technology for the financial support of this research through the project TRA2007-67961-C03/AUT and the Regional Government of Castile and Leon through the funding for the GR203 Excellence Research Group.

Climate refugees, vulnerability and international protection

La cifra sobre desplazamiento forzoso en el mundo alcanza máximos históricos, y se verá incrementada en el futuro debido al desplazamiento humano que provoca el calentamiento del planeta y la degradación ecológica que caracteriza la actual era del Antropoceno. La protección internacional que otorga el derecho a las personas que huyen de sus tierras y buscan refugio está relacionada con la exposición a peligros, la vulnerabilidad y la dificultad de estas personas para ejercer sus derechos humanos. La movilidad por causas ambientales provoca nuevos motivos de protección jurídica no previstos en la Convención sobre el estatuto de los refugiados, pero a la que hay que dar respuesta y solución. En el siglo xxi Naciones Unidas consolida un nuevo enfoque de los derechos humanos con relación al cambio climático y las migraciones, y este paradigma debe resolver el vacío de la doctrina jurídica tradicional para abordar el problema de las migraciones climáticas. También se encuentran en situación de vulnerabilidad, junto a las mujeres y los menores, que sí son reconocidas y protegidas por el derecho, y los jóvenes varones refugiados, muchos de los cuales se ven abocados a ejercer la prostitución para sobrevivir. A la reflexión sobre los conceptos de refugiado/migración y al análisis de los nuevos motivos de vulnerabilidad por razones del cambio climático se dedica el presente trabajo, para evidenciar que el actual modelo migratorio de defensa de frontera actúa en sentido opuesto a la solución real de un movimiento creciente de personas vulnerables que deambula por el mundo en busca de refugio.The forced displacement in the world reaches historical maximums, and it will increase in the future due to the human displace - ment caused by global warming and the ecological degradation that characterizes the era of the Anthropocene. The international protection that the law gives to refugees is related to their exposure to dangers, vulnerability and difficulty in managing their human rights. Mobility due to environmental causes gives rise to new reasons for legal protec - tion not provided for in the Convention of Refugees (1951), but which must be answered and resolved. In the 21st century, the United Na - tions consolidated a new approach to human rights in relation to cli - mate change and migration, and this paradigm must bridge the gap in traditional legal doctrine to resolve the problem of climate migration. Along with women and minors who are recognized and protected by law, young male refugees are also in a vulnerable situation, many of them being forced into prostitution to survive. This article aims to re - flect on the terms “refugee” and “migration”, and to analyse new rea - sons for vulnerability, so as to prove that the current migratory model of border defense runs counter to the real solution of a growing movement of vulnerable people who go around the world in search of refuge.Filosofí

Uso/ abuso del móvil y sueño en adolescentes de 13 a 18 años

Introducción: En los últimos años el uso del móvil ha cambiado considerablemente. Los adolescentes son considerados un grupo de riesgo frente a las nuevas tecnologías ya que han nacido inmersas en ellas. Material y métodos: se llevó a cabo una revisión sistemática de 40 estudios de investigación sobre el uso/ abuso que hacen los jóvenes entre 13 y 18 años del móvil y su relación con el sueño. Resultados: El 52% de los sujetos adolescentes que utilizan el móvil tiene peor calidad del sueño. El 57% de jóvenes entre 13 y 18 años hace un mal uso del móvil o abusa de él, se ha relacionado el abuso del móvil con sintomatología ansiosa y depresiva. Conclusiones: El móvil interfiere de manera considerable en la calidad del sueño de los adolescentes, disminuyendo su energía y rendimiento por el día. Genera una dependencia emocional que puede llevar a los jóvenes a problemas de ansiedad o depresión. A su vez el mal uso del móvil correlaciona con la autoestima de forma que, a mayor autoestima, menor uso problemático del móvil.Introduction: in recent years the use of the mobile phone has changed considerably. Teenagers are considered a risk group against new techologies as they have been born immersed in them. Material and methods: a systematic revision was carried out, counting with 40 studies of investigation about the use/abuse of the mobile phone that the youth between 13 and 18 do, emphasizing its night time usage. Results: a 52% of teenagers that were using their phones when they went to bed proved a worse sleep quality. A 57% of young people misuses or abuses of it, being related mobile phone abuse with an anxious and depressive symptomatology. Conlusions: mobiles interfere considerably in teens' sleep quality, draining their energy and their daily performance. Moreover, it generates an emotional dependence that can lead to young people to anxiety or depression problems. Furthermore, mobile phone misuse is related with self esteem, being the more self esteem, the less problematic misuse of the mobile phone.Psicologí

Una aproximació a la diversitat sexual des de l’àlbum Rei i rei de Linda de Haan i Stern Nijland

Treball Final de Grau en Mestre o Mestra d'Educació Primària. Codi: MP1040. Curs acadèmic: 2020/2021Rei i rei narra la història d’un jove príncep que encara no està casat. Un dia, la seua mare li insisteix que ha de trobar una princesa per a casar-se. El príncep li respon a sa mare que a ell mai li han agradat massa les princeses. Sa mare convida al seu castell a moltes princeses perquè desfilen amb l’objectiu de despertar l’interès del seu fill, el príncep. Al cap d’un temps, arriba la princesa Madaleine, acompanyada pel seu germà, el príncep Lee. Tots dos prínceps s’enamoren immediatament i ,finalment, es casen i viuen junts com a rei i rei. L’àlbum narra la història d’una manera molt natural i adequada que fa que els estereotips referents al matrimoni homosexual desapareguen. Gràcies a la seua qualitat estètica i literària trobe que és un àlbum molt bo per a reflexionar al voltant de la diversitat sexual i la naturalitat amb la qual s’ha de tractar

Public access to documents supports transparency in public administration

Transparency in public administration is possible if citizens are guaranteed access to documents. In this paper we propose a definition of transparency and analyse the Spanish legislation that addresses the right of access to information. Transparency is also more readily achieved if institutions have organized their archives. We propose essential requirements that must meet the legal and records management standards
