Suspensión del contrato de trabajo y reducciones de jornada por causas objetivas

El presente ensayo analiza el régimen jurídico de dos medidas de reorganización empresarial en el ámbito de los recursos humanos, a las que pueden acudir las empresas para ajustar el factor trabajo al nuevo escenario creado por la situación de crisis, permitiéndoles un cambio en la dinámica negativa que atraviesan y, junto con otras medidas no laborales, ayudar a vadear la actual situación: las suspensiones de contratos de trabajo por causas económicas, técnicas, organizativas o productivas y las reducciones de jornada, tanto definitivas como temporales._________________________________________________This essay analyzes the legal status of two measures of corporate reorganization in the field of human resources at companies that can contribute to adjust the labor factor to the new situation created by the crisis, in order to allow a dynamic change in the negative crossing and, together with other non-work measures, help to overcome the current situation: the suspension of employment contracts for economic, technical, organizational or productive reasons and reductions of time work in both types, temporary and definitive

Wavelet Transform-Based Phylogenetic Analysis of Protein Sequences

With the acceleration of gene sequencing studies, many biological data emerges. By analyzing these data, it contributes greatly to the studies on understanding the metabolic disorders in the organism and increasing the efficiency of the drugs. For this purpose, it is critical to classify the data in a way that is accurate, fast and low-cost according to its characteristics and relationships. Besides experimental methods, machine learning and bioinformatics methods are used. Artificial neural networks, support vector machines, flexible calculation methods are frequently used methods. However, the effectiveness of these methods on biosecence data depends on the method of using the method with the most appropriate parameters and converting protein sequences into numerical sequences. When the sequences are transformed with amino acid frequencies, the properties of amino acids are ignored. For this purpose, handling the physicochemical (hydrophobicity, hydrophilicity ...) properties of amino acids increases the performance of classification techniques. The phylogenetic tree is the best method to visualize the classification among species. In the project, the wavelet transform used in the analysis of digital signals has been adapted to protein sequences defined by hydrophobicity values. Each protein sequence was defined to correspond to a signal, the wavelet transform was divided into approach and detail components, and the similarities between them were calculated, and the phylogenetic tree of the species was created. As an application, phylogenetic trees of ND5 protein sequences of 22 species were created in the MatlabR2017 program of NeighborJoining (NJ) and Unweighed Pair Group Method of Aritmetic Averages (UPGMA) methods

A novel application of queueing theory on the Caulerpenyne secreted by invasive Caulerpa taxifolia (Vahl) C.Agardh (Ulvophyceae, Caulerpales): a preliminary study

Aquarium originated marine green alga Caulerpa taxifolia was introduced into the Mediterranean Sea accidentally in 1984. This invasion has been negatively affecting the sub-littoral ecosystem of the Mediterranean. One of the important reasons for its success in the Mediterranean is its secondary toxic metabolite called caulerpenyne (CPN). Furthermore, CPN has anti-proliferative and apoptotic activities, therefore, CPN can be considered as a potential native source in cancer therapy. For that reason, modeling this metabolite might be of importance. Increase and decrease of the CPN level before reaching the critical level can be expressed by means of a queueing system in which the number of ‘customers' increases and decreases. In fact, production of CPN shows fluctuations for many environmental reasons, which allow us to apply queueing theory. In the present study, the expected time to reach the maximum caulerpenyne level was analyzed and evaluated using queueing theory

Olhares sobre a Organização e o Funcionamento de um Departamento Curricular de 1º Ciclo – desafios e propostas para aprender a melhorar em conjunto.

Resumo O estudo que se apresenta foi desenvolvido no âmbito da dissertação de Mestrado em Administração Educacional que desenvolvemos. Teve como curiosidade inicial, conhecer e compreender a organização e o funcionamento do Departamento do 1º Ciclo do Ensino Básico de um colégio privado, centrando-se as atenções nas dimensões sociais, dinâmicas e acções dos respectivos docentes. Adoptando uma metodologia qualitativa, conjugámos a análise documental, focus group e entrevistas semiestruturadas, envolvendo um conjunto de oito participantes. Das reflexões finais que a triangulação de dados seguida de análise de conteúdo nos permitiram, destacamos a importância do Projecto Educativo enquanto elemento estruturante e orientador da acção dos professores e da escola como um todo organizacional. Manifestando todos os participantes um bom conhecimento da visão, missão e objectivos nele plasmados, percebemos que dele resulta uma partilha de responsabilidades e compreendemos que as funções de cada elemento são bem definidas e assumidas em grupo. Identificamos ainda o importante papel da gestão intermédia, reconhecendo na directora do 1º Ciclo um elemento fundamental na promoção das interacções entre pares e de práticas colaborativas entre eles e com as famílias. Compreendemos que ainda há um caminho a percorrer, no sentido da cooperação no Departamento e entre Departamentos, pelo que um investimento em formação e desenvolvimento profissional nos pareceram relevantes para um emergente desenvolvimento organizacional. Apontamos necessidades de espaços sociais, onde o trabalho conjunto, a partilha de experiências e as dinâmicas interactivas sejam os alicerces para a construção de projectos comuns e espaços onde todos aprendam

Seasonal rubisco enzyme activities and caulerpenyne levels in invasive Caulerpa racemosa var. cylindracea and native Caulerpa prolifera

Caulerpa racemosa var.cylindracea (C.racemosa) is an invasive marine seaweed in the Mediterranean Sea. Since no valid eradication method has been existed in the scientific literature on this species, it has currently been continuing its invasion along the coastlines of 13 Mediterranean countries. One of the important factors responsible for its invasion is thought as its toxic secondary metabolite, caulerpenyne (CYN). The present paper investigates seasonal changes in the secondary metabolite CYN, and rubisco enzyme (EC 4.1.1.39) activities of the invasive C. racemosa and native C. prolifera. Inasmuch as no correlation between CYN level and rubisco enzymic activity was observed in these species, it is considered that the regulation of CYN synthesis caulerpenyne and rubisco enzymic activity might be controlled independently. In conclusion, the further analysis on the rubisco enzymic activity determinations with MEP and mevalonate pathway which are considered responsible for CYN bio-synthesis should be studied in great detail in invasive and native Caulerpa species in the Mediterranean Sea to get the overall picture

Los liberados sindicales en el sector público

El presente ensayo analiza el régimen jurídico del liberado sindical en las Administraciones Públicas. Tras la delimitación conceptual de la figura, se exponen las diversas vías de acceso a la condición de liberado sindical en el sector público, prestando atención a las especialidades derivadas del tipo de vínculo, laboral o funcional, que dichos liberados mantienen con la Administración. Seguidamente se examinan los derechos profesionales de los liberados sindicales e institucionales, con especial referencia a los derechos retributivos, concluyendo con la exposición de algunos problemas prácticos que ha suscitado el ejercicio del derecho de huelga por parte del liberado

La regulación legal del trabajo asalariado en la agricultura

El Derecho del Trabajo ha proporcionado históricamente, con intensidad variable y res-pecto de diversos bloques o conjuntos normativos (edad de acceso al trabajo, jornada y descansos, implantación de órganos representativos de los intereses de los trabajadores en la empresa, protección frente a los riesgos sociales...) un tratamiento dispar a los trabajadores agrícolas, con el resultado para éstos de una protección jurídica de peor condición que la recibida por los trabajadores de la industria y del sector servicios. La tendencia dominante en la legislación actual parece avanzar, sin embargo, por el camino de la unificación u homogeneización de las condiciones laborales en cualesquiera actividades, mediante la conexión entre las diversas realidades económicas y el intento de racionalización del mercado de trabajo en su complitud. De hecho, han desaparecido del vigente Ordenamiento -cuando menos en el texto de la ley- buena parte de las diferenciaciones normativas que, en algunos casos hasta fechas recientes, han «padecido» los trabajadores del campo
