Re-Programming Hydrogel Properties using a Fuel-driven Reaction Cycle
Authors: Singh Nishant , Lainer Bruno , Formon Georges , De Piccoli Serena , Hermans Thomas
Published: October 2019

Nature uses catalysis as an indispensable tool to control assembly and reaction cycles in vital non-equilibrium supramolecular processes. For instance, enzymatic methionine oxidation regulates actin (dis)assembly, and catalytic guanosine triphosphate hydrolysis is found in tubulin (dis)assembly. Here we present a completely artificial reaction cycle which is driven by a chemical fuel that is catalytically obtained from a ‘pre-fuel’. The reaction cycle controls the disassembly and re-assembly of a hydrogel, where the rate of pre-fuel turnover dictates the morphology as well as the mechanical properties. By adding additional fresh aliquots of fuel and removing waste, the hydrogels can be re-programmed time after time. Overall, we show how catalysis can control fuel generation to control reaction / assembly kinetics and materials properties in life-like non-equilibrium systems.
Multiphase Complex Coacervate Droplets
Authors: Lu Tie-Mei , Spruijt Evan
Published: October 2019

Liquid-liquid phase separation plays an important role in cellular organization. Many subcellular condensed bodies are hierarchically organized into multiple coexisting domains or layers. However, our molecular understanding of the assembly and internal organization of these multicomponent droplets is still incomplete, and rules for the coexistence of condensed phases are lacking. Here, we show that the formation of hierarchically organized multiphase droplets with up to three coexisting layers is a generic phenomenon in mixtures of complex coacervates, which serve as models of charge-driven liquid-liquid phase separated systems. We present simple theoretical guidelines to explain both the emergence and stability of multiphase droplets using the interfacial tension and mean-field interaction parameter as inputs. Coexistence implies differences in macromolecular density, which can be inferred from critical salt concentrations. We show that the coexisting coacervates present distinct chemical environments by concentrating guest molecules in different domains of the multiphase droplets. Our findings suggest that condensate immiscibility may be a very general feature in biological systems, which could be exploited to design self-organized synthetic compartments to control biomolecular processes.

To determine the changes in Malondialdehyde (MDA) levels in addition to measuring the changes in the activity of superoxide dismutase (SOD) and catalase (CAT) which considered as antioxidant enzymes in autistic children receiving melatonin supplementation to evaluate its antioxidant role in autism. A follow-up study was performed in therapeutics and clinical pharmacy Department, Baghdad College of Medical Sciences, Baghdad - Iraq. The study was performed on 55 autistic children who had recruited from several private institutions specialized in autistic children care, Baghdad, Iraq between June 2018 and November 2018. The levels of melatonin, MDA, SOD and CAT were measured in the serum of 55 patients before and after receiving melatonin supplementation for three months. The results revealed statistically significant differences in the levels of melatonin, MDA, SOD and CAT between patients before and after receiving melatonin supplement. Furthermore, melatonin levels showed significant positive correlations with both SOD and CAT in addition to a significant positive correlation between SOD and CAT while MDA levels showed significant negative correlations with melatonin, SOD and CAT in autistic patients before and after receiving the supplement. Melatonin levels, CAT and SOD activity, showed to be improved significantly by melatonin supplementation with a concomitant reduction in the levels of MDA as an indicator of a decrease in oxidative stress in autistic children.

Authors: Ali Asif , Azam Muhammad , Mattiullah Jawairyiah , Akhtar Adeel
Published: October 2019

Background: Individuals with low level of trait self-control exhibit several negative behaviors such as violence, addictive behaviors (drug addiction, technological addictions), suicide, unhealthy eating, and criminal behaviors. In contrast, high level of self-control thought to be associated with positive psychosocial and physical health related outcomes. Interventions contribute to boost self-control seems essential for individual with risk of low trait self-control.

Objectives: The purpose of this study is to systematically evaluate the relationship between physical activity and trait self-control.

Methods: For this purpose, full-text articles were searched in research databases including Psych INFO, PubMed, Medline, The Cochrane Library, Wiley Library, Taylor & Francis, Science Direct, Springer, ERIC, JSTOR, Google scholar, and Sage Journals.  Following screening for the study selection criteria and assessment of risk of bias, twenty one studies (13cross-sectional, 5 longitudinal and 3 interventions) with low or moderate risks of bias were finally selected for qualitative synthesis.

Results: Findings from all of the included studies consistently showed that there was a significantly positive relationship between physical activity and trait self-control.It is suggested that increasing self-efficacy, decreasing aggression, and improvement in positive and negative emotional states might be underlying mechanisms working for beneficial effects of physical activity on trait self-control.

Conclusion: These suggest that physical activity and exercise may serve as a potential means to enhance trait self-control. Practical implementation and recommendations for policy makers are put forward in this connection.

This paper examines the drivers and barriers to adopt sustainability practices in Pakistani SMEs. Corporate sustainability has become important issue during the last few decades. Existing literature focus on large companies and thereby paid limited attention to SMEs. There is an increased understanding that SMEs should focus on sustainability practices to remain competitive. There is limited research that capture the extent of adoption of sustainability practices as well as its drivers and barriers. This paper fills the gap and uses institutional theory to explain the drivers and barriers of sustainability practices in SMEs of Pakistan. This qualitative research was conducted in Multan, Pakistan where interviewees from the managers of eight SMEs in the manufacturing sector were conducted. In addition to this questionnaire was sent to SMEs in order to capture the extent of the adoption of sustainability practices. The research findings show certain drivers: commitment by top management, competitor pressure, stakeholders’ pressure and barriers: lack of resources, lack of training and education and lack of awareness for the adoption of sustainability practices. This paper contributes to the sustainability literature in emerging and developing countries. Through an increased awareness of drivers and barriers, policy makers and practitioners may take necessary steps to improve sustainability practices in SMEs

The problem is when foreign signals captured, then the roaming rate charged. Some people avoid it by switching their simcard to a local simcard. Some people in border area using local simcard (from Indonesian service providers) some use foreign simcard, and other use mixed of them (local and foreign). Knowing about border crosser behavior in using simcard is important not only for the telecommunication service provider but also for the government. The study aims to estimate the number of border crosser based on their behavior in using simcards when entering Indonesia. This study uses data from Survey of Foreign Tourist Based on Mobile Positioning Data conducted by Statistics Indonesia in 2017. Based on that survey, there were 28.305 of border crosser having cellphones. The method of analysis is  multinomial logistic regression. The responsese variable is the behavior of using simcard with 3 categories; foreign, local, and mixed.  The model fit the data well. The result show that 53,8 percent of border crosser are foreigners most of them entering Indonesia through Kalimantan. The use of simcard in the boundaries area is significantly influenced by sex, age, purpose to visit Indonesia, and region. There are 7,3 percent of foreigner use mixed cards and only 1,4 percent use local cards. For border crossers from Indonesia, there is 99,7 percent use local cards while the other 0,3 percent use mixed cards and no one uses foreign cards.

OBLIGACIONES EN EL CONTRATO DE TRABAJO: ALGUNOS PROBLEMAS EN LA DETERMINACIÓN Y EQUIVALENCIA DE LAS PRESTACIONES
Authors: Barretto Ghione Hugo
Published: October 2019

La noción de “contrato” de trabajo ha sido discutida por la dificultad de asimilar las particularidades del trabajo subordinado a una figura creada bajo el parámetro de la igualdad formal y la autonomía de los sujetos pactantes. La “contractualización” de los derechos fundamentales del trabajador no se encuentra suficientemente justificada en tanto los derechos proceden de fuentes diversas al acuerdo de voluntades y además, su reclusión contractual pude presentar algunas consecuencias no deseadas. El artículo se interroga además sobre como es si resulta posible admitir la “equivalencia de gravámenes” y la interdependencia de las obligaciones en el “contrato”, dejando en este caso abierta la cuestión al planteamiento de algunas alternativas para intentar reconstituir la bilateralidade.

A REALIDADE DA JURISDIÇÃO CONSTITUCIONAL EXERCIDA PELOS JUÍZES ORDINÁRIOS: UMA ANÁLISE COMPARADA DAS EXPERIÊNCIAS DE ESPANHA E ITÁLIA
Authors: Firmino Santiago Marcus
Published: October 2019

Nas últimas décadas a jurisdição constitucional no Brasil tem passado por um progressivo processo de concentração, esvaziando as competências dos juízes ordinários e conferindo crescente vinculatividade às decisões do Supremo Tribunal Federal. Este movimento é frequentemente justificado invocando-se o referencial das Cortes Constitucionais europeias e sua atuação exclusiva no controle de constitucionalidade, sempre visto como um exemplo de sucesso tanto no plano jurisdicional quanto administrativo. Tal análise, contudo, mostra-se equivocada, na medida em que diversos países daquele continente têm incorporado elementos típicos do modelo difuso norte-americano, renunciando a um sistema puramente concentrado. Este artigo busca, a partir do estudo da realidade vivida em Itália e Espanha, discutir os rumos adotados para a jurisdição constitucional brasileira, apontando-se o equívoco em limitar a capacidade decisória dos juízes ordinários em matéria constitucional.
SEGURIDADE SOCIAL, PROIBIÇÃO DO RETROCESSO E SUSTENTABILIDADE DAS POLÍTICAS PÚBLICAS
Authors: Borsio Marcelo
Published: October 2019

As políticas públicas estatais são criadas para melhor atender os anseios sociais, pelo menos deveriam. Estados Modernos agem deste modo. Deve haver harmonia entre Estado esuas competências. Política pública é ação de governo, mas com representatividade social. Um dos programas de política pública bem definidos é o estruturado na Seguridade Social da Constituição Federal de 1988. Direitos sociais devem ter efetividade, mormento os assistenciais, posto a miserabilidade dos hippossuficientes. Programas assistencialistas, como fome zero, bolsa família, entre outros devem ser mantidos com responsabilidade sem clientelismo político, com intensões outras. A concessão de benefícios não-contributivos deve sempre estar atrelada à preservação de equilíbrio financeiro e atuarial. E para isso, também os contributivos devem seguir mesmo formato, nunca se esquivando da proibição do retrocesso, em face de direitos sociais já conquistados.Se o Estado pode ser assistencialista, deve manter conquistas sociais aos trabalhadores da sociedade. O trabalho abaixo busca trazer fiel da balança entre essa possível contradição estatal, que procura manter um assistencialismo clientelista e passa ao largo da preservação de direitos previdenciários adquiridos em torno das normas aos beneficiários do seguro social.

Authors: Däubler Wolfgang
Published: October 2019

The capitalist economic system treats the worker as a commodity, an object, in contradiction to the idea of human dignity. However, there are mitigations to this trend: the qualification of the worker, the protection of labor laws, the role of collective bargaining, the unwritten rules of coexistence among enterprises, their workers and society itself. Nevertheless, the inherent market forces such as globalization, neoliberalism and generalized social and economic deregulation flaunt more strength. The counterpoint to this weakening process of Unions, collective bargaining and strikes involves the search for new and efficient practices by the Union movement, among which stand out the actions in virtual network (network), the mechanisms of sensitization and mobilization of public opinion and diversification of the legal action of the Unions.
LA SUBCONTRATACIÓN COMO INSTRUMENTO DE DESCENTRALIZACIÓN PRODUCTIVA Y SU INCIDENCIA JURÍDICO-LABORAL (PARTE 1)
Authors: Luis Monereo Pérez José
Published: October 2019

En las últimas décadas, la subcontratación ha dejado de ser un fenómeno relativamente marginal para convertirse en un elemento estructural de gran parte de los procesos productivos. No se trata, desde luego, ante un fenómeno absolutamente nuevo, pero hoy se asiste a una extraordinaria expansión de esta forma de organización empresarial. El Ordenamiento Laboral tiene que dar una respuesta de política del Derecho autorreflexiva, autónoma y garantista -coherente con la Constitución del Estado Social- a nuevo escenario de la organización de los sistemas productivos en constante transformación; aspecto que hoy no se cumple satisfactoriamente. Las “regulaciones” o pretendidas “desregulaciones” normativas liberalizadoras del fenómeno de la subcontratación son en sí mismas desequilibradas, pues favorecen unilateralmente los intereses y libertades de organización empresarial y contribuyen decisivamente a generalizar (desde una “racionalización económica” contrapuesta a la “racionalidad social”) la precarización y mercantilización de las relaciones de trabajo. La nueva organización productiva hace que se tenga que replantear el régimen jurídico laboral de la subcontratación, régimen insuficiente para hacer frente a las nuevas realidades de organización empresarial
LA SITUACIÓN JURÍDICA DE LOS “EXPATRIADOS” LABORALES
Authors: Ojeda Avilés Antonio
Published: October 2019

El concepto y regulación de trabajadores desplazados es el más conocido y aplicado dentro de la Unión Europea para designar a quienes son enviados por su empresa temporalmente a otro país europeo, pero fuera de nuestra Unión el concepto universalmente utilizado es el de expatriado. Este artículo analiza sus diferencias con el desplazado y el emigrante, así como la situación legal y las normas que regulan el viaje, residencia, trabajo y repatriación de ellos, incluyendo las políticas de asignaciones internacionales de algunas multinacionales, y la legislación de expatriados de los países de acogida, tomando como ejemplo la legislación de Emiratos Árabes Unidos.
A ASSISTÊNCIA SOCIAL COMO SUBSISTEMA SUBSIDIÁRIO NA SEGURIDADE SOCIAL E O VALOR DO BENEFÍCIO PREVISTO NO ART. 203, V, DA CONSTITUIÇÃO: UMA ANÁLISE A PARTIR DO RELATÓRIO BEVERIDGE
Authors: Luiza Pierdoná Zélia
Published: October 2019

O presente trabalho tem por objetivo demonstrar que a Constituição de 1988 instituiu um sistema de proteção social denominado seguridade social, o qual tem por objetivo proteger a todos os cidadãos nas situações de necessidade. Para atender ao referido objetivo, foram criados três subsistemas: o da saúde, o da previdência e o da assistência. Assim, devese compreender os diferentes subsistemas a partir do conjunto, bem como que o subsistema assistencial apresenta-se como subsidiário ao subsistema previdenciário. A partir dessa compreensão, extraída do modelo proposto no Relatório Beverige, será analisada se o benefício de um salário mínimo, destinado aos idosos e aos deficientes, previsto no art. 203, V, da Constituição, deve ser mantido ou se precisa ser alterado, para garantir a coerência do sistema de proteção social.
POR CAUSA DEL EJERCICIO DEL DERECHO FUNDAMENTAL DE LIBERTAD SINDICAL NADIE TIENE QUE SUFRIR DAÑOS O REPRESALIAS QUE ATENTEN CONTRA ESTE DERECHO FUNDAMENTAL. LA GARANTÍA DE INDEMNIDAD EN CLAVE SINDICAL EN LA DOCTRINA DEL TRIBUNAL CONSTITUCIONAL ESPAÑOL
Authors: Ignacio García Ninet José , Barbancho Tovillas Fernando , Barceló Fernández Jesús
Published: October 2019

Cuando hablamos de la garantía de indemnidad estamos hablando de que por causa del ejercicio del derecho fundamental de la libertad sindical nadie tiene por qué sufrir ningún tipo de represalias que atenten contra este derecho fundamental por el hecho de su disfrute o intento de disfrute, ni tampoco por el hecho de que, en defensa del derecho de libertad sindical, pudiera presentar, las más de las veces en interés colectivo, quejas, reclamaciones, denuncias, demandas o recursos, de modo muy especial cuando frente al legítimo ejercicio de este derecho se deriva por parte el temor, incluso, a la máxima sanción que no es otra que la del despido.
ANÁLISIS CRÍTICO DE LA DOCTRINA DE LA CORTE SUPREMA DE JUSTICIA DE LA NACIÓN ARGENTINA EN MATERIA DE TITULARIDAD DEL DERECHO DE HUELGA
Authors: Zas Oscar
Published: October 2019

Este trabajo analiza críticamente una reciente sentencia de la Corte Suprema de Justicia de Argentina que restringe la titularidad del derecho a declarar la huelga a los sindicatos formalizados e inscriptos. Para estos efectos, se estudian las normas de jerarquía constitucional y supralegal vigentes en Argentina que regulan el referido derecho y se las interpreta a la luz de los principios y reglas del Derecho Internacional de los Derechos Humanos. Como conclusión de ese análisis, surge una tesis amplia: la huelga es un derecho que puede ser declarado por una pluralidad de trabajadores o por los sindicatos.
NOTION DE CONTRAT DE TRAVAIL
Authors: Dockès Emmanuel
Published: October 2019

Le but de cet article est discuter la notion de contrat de travail. C’est une question toujours actuelle parce qu’elle détermine qui bénéficie des protections du droit du travail et aussi du droit de la sécurité sociale. Le contrat de travail est traditionnellement présenté comme un composé de trois éléments: travail, salaire et subordination. Cette dernière est le plus importante des éléments. On montre que le “lien juridique de subordination” a eté remplacé par le “l’état de subordination” et on réevalue la dépendance économique. On montre aussi que la répartition des risques économiques entre l’employeur et le salarié ne peut pas avoir influence sur la qualification de contrat de travail. On conclut que la subordination est composée de direction, contrôle et capacité à prendre des sanctions. C’est la présence de ces éléments en fait, dans la pratique, qui importe (“état de subordination”). Le critère central du contrat de travail apparaît alors être un composé de subordination et de dépendance, cet-à-dire, l’intensité de l’un de ces éléments permet de suppléer la faiblesse de l’autre
O TERCEIRO PROTOCOLO FACULTATIVO À CONVENÇÃO SOBRE OS DIREITOS DA CRIANÇA
Authors: Carbonelli Matteo
Published: October 2019

O presente artigo visa ao estudo do terceiro Protocolo Facultativo à Convenção sobre os Direitos da Criança da ONU, adotado no dia 19 de dezembro de 2011 e vigente a partir do dia 14 de abril de 2014. A inovação mais relevante desse Protocolo é a criação do Comitê para os Direitos da Criança, perante o qual podem ser levadas as violações dos direitos previstos na referida Convenção e nos dois Protocolos Facultativos anteriores. Diferentemente dos sistemas criados por outras convenções em matéria de direitos humanos, antes do Protocolo em tela não havia a previsão de um órgão com competência para examinar casos de violações com um procedimento do tipo para-jurisdicional. São assim examinados os dispositivos do Protocolo, em especial os que preveem o procedimento das comunicações individuais, as suas condições de admissibilidade, o seu desenvolvimento e os respectivos resultados. Trata-se, ainda, do procedimento das comunicações interestatais e do procedimento de investigação. Por fim, conclui-se que, embora com alguns pontos fracos, o Protocolo constitui um notável passo adiante no fortalecimento da tutela dos direitos das crianças com a afirmação concreta do princípio do interesse superior do menor e do seu direito a ser ouvido.
LA TEOLOGÍA DEL TRABAJO EN LA METAMORFOSIS DE KAFKA
Authors: Loy Gianni
Published: October 2019

El objetivo del presente artículo es estudiar la teología del trabajo en la obra Metamorfosis de Franz Kafka. Inicialmente se destaca que aún que la crítica tenga siempre estudiado esa obra para mejor conocer a Kafka y sus relaciones familiares, en realidad la Metamorfosis constituye una extraordinaria visión del trabajo y de su teología. En tal sentido la transformación del protagonista Gregor Samsa en un insecto simboliza el daño producido por la exposición al riesgo, o sea, al estrés de su trabajo. El protagonista no se preocupa por el hecho de que su cuerpo se transformó en insecto pero sí que no podría cumplir su obligación de trabajar y sentía miedo del despido. No le gusta su trabajo pero no lo quita porque sirve para mantener a toda la familia y para pagar la deuda que el padre había contraído con su jefe (“pecado original”). Así en la primera parte del libro la mística del trabajo coincide con la visión bíblica, común al hebraísmo y al cristianismo. El sufrimiento del trabajo surge de la necesidad de ganarse el pan y de la expiación del pecado original. Se evidencia que Franz Kafka proyectó sobre Gregor Samsa su propia historia personal de trabajador. La segunda parte del libro trata de la expiación: como Gregor Samsa no puede trabajar sus familiares son echados del paraíso terrestre y tendrán que ganar el pan con el sudor de su frente. Se evidencia un modelo negativo, que considera al incapaz (Gregor Samsa) como un peso y se propone eliminarlo. En la tercera parte, de la redención, Gregor Samsa se abandona a la muerte para redimir a sus familiares ingratos y permitirles una nueva vida. Los familiares a partir de ahora tienen que soportar la pena del trabajo para que se cumpla el castigo que ha pasado de generación en generación. Pero gradualmente se acercan a aquel trabajo que ha sido revalorizado por la doctrina social de la Iglesia, que les hace partícipes de la obra de la creación. Se evidencia al final la gran implicación de Kafka con el Derecho del Trabajo incluso expresa en la Metamorfosis.
