¿Es posible que la prestación de servicios fuera de la esfera del derecho laboral?
Authors: Silva Méndez Jorge Luis
Published: January 2020

Cuando un individuo presta servicios subordinados a otro, ocurre una relación laboral, lo que implica que el patrón adquiere varias obligaciones legales que pueden representar un alto costo. Aunque es posible contratar a un individuo bajo regímenes jurídicos distintos al laboral, en la práctica es complicado debido a la naturaleza expansiva del principio de subordinación, elemento fundamental del derecho laboral mexicano. Este artículo analiza, a partir de lo dicho en la Ley Federal del Trabajo, la jurisprudencia y la doctrina, la prestación de servicios bajo modalidades distintas a la relación laboral. Al final se propone una regla de interpretación para determinar la legalidad de la prestación de servicios fuera de la esfera del derecho laboral.
¿Cómo fortalecer el Poder Legislativo federal en México? El caso de la reelección inmediata de los miembros del Congreso
Authors: Jaimes Delgado David Alberto
Published: January 2020

Hoy en día el tema de la reelección legislativa inmediata es una de las asignaturas pendientes y largamente postergadas en la agenda del Poder Legislativo federal mexicano, dicha reforma que forma parte de la también largamente esperada reforma del Estado es de vital importancia si de verdad queremos contar con legisladores profesionales, expertos y responsables ante los ciudadanos. Así pues, el presente trabajo se estructura en seis pequeños apartados en los cuales se hace un breve recuento histórico de las principales causas que motivaron esta, sin duda grave, anomalía constitucional, así como las consecuencias que la implementación de la misma ha traído al interior del Poder Legislativo en México y al Estado en su conjunto
Derecho y libertad
Authors: Villanueva Fernanda
Published: January 2020

Este trabajo explora las relaciones entre la libertad metafísica y la jurídica. La primera, aun cuando se le considera como una necesidad para el ser humano, es cuestionada por el mecanicismo; la segunda se reduce a lo permitido, lo ordenado y lo prohibido por las normas jurídicas, concibiéndose históricamente como una libertad negativa. Sin embargo, si a pesar de algunas asimetrías existe una relación con la libertad metafísica deberá entenderse al derecho como afirmando la libertad positiva que propicia el florecimiento de las personas. En esta línea, se propone una lectura creativa de la Constitución y de tres tipos de libertades que ésta protege, a saber, la libertad religiosa, la de expresión y la de movimiento. Partiendo de la obligación del Estado a impartir educación, según las especificaciones constitucionales, encontraremos que de cumplirse este artículo se dotaría de capacidades y disposiciones a las personas para resistir a cualquier persona o institución que quiera restringir o eliminar sus libertades; más aun, al afirmar esa libertad en una forma creativa se propiciará su florecimiento.
Primeras implicaciones del caso Radilla
Authors: Cossío D. José Ramón
Published: January 2020

Este artículo se centra en la histórica sentencia dictada por la Suprema Corte de Justicia de la Nación en el expediente Varios 912/2010 que establece el nuevo modelo de control de regularidad constitucional en el ordenamiento jurídico mexicano. A partir de las reformas constitucionales en materia de derechos humanos y juicio de amparo de junio de 2011 y de la necesidad de insertar en el orden jurídico la sentencia dictada por la Corte Interamericana de Derechos Humanos en el caso de Rosendo Radilla contra el Estado mexicano, la Suprema Corte da una solución integral acerca de cómo los juzgadores deben actualizar el principio de supremacía constitucional. Se analizan las implicaciones generales derivadas de esta relevante sentencia que, además de reconocer la obligatoriedad de las resoluciones dictadas por la Corte Interamericana de Derechos Humanos respecto del Estado mexicano, establece un nuevo tipo de control de la regularidad de los actos de autoridad —el control difuso por parte de la totalidad de los juzgadores del país—, y precisa el nuevo parámetro de dicho control, que incluye las normas de derechos humanos previstas en tratados internacionales.
Balance de derechos en dos reformas penales
Authors: Farías Calderón Ana Gabriela
Published: January 2020

Asimismo, con el fin de analizar la oferta de derechos en el proceso, se describen las etapas procesales penales en las dos mencionadas entidades federativas. Se concluye que la legislación de Nuevo León dista de apegarse a los preceptos constitucionales, mientras que la de Chihuahua, a pesar de algunos fallos, está más de acuerdo con éstos.
La dinámica constitucional: un sistema caótico
Authors: Torre Torres Rosa María de la , Jara Guerrero Salvador
Published: January 2020

El presente trabajo, es resultado de un ejercicio de reflexión desde dos disciplinas que en apariencia están desvinculadas: el derecho y la física. En el texto del artículo, los autores exploran, desde una versión interdisciplinaria, la idea de concebir el sistema constitucional más que como un sistema completo y autopoyético, como un sistema dinámico, complejo e incluso caótico. Partiendo del estudio de la teoría de los sistemas complejos establecida en la Física, se incorporan elementos interpretativos y argumentativos para identificar la dinámica constitucional como un sistema no lineal, evidentemente dinámico y con una complejidad cercana al caos. Pero es de resaltar que uno de los objetivos principales de los autores es, eliminar toda carga peyorativa al adjetivo caótico, abriendo la posibilidad a una concepción favorable del caos en el sistema constitucional.
El solvet et repete en el panorama tributario cubano: privilegio administrativo que limita el ejercicio de derechos humanos
Authors: Bencomo Fariñas Yaneisi
Published: January 2020

En el presente trabajo se realiza una valoración del tratamiento técnico-jurídico que se le da a los derechos humanos en la Constitución cubana, reflexionándose en torno a sus aciertos e insuficiencias. De forma paralela se enfatiza en la necesidad de que cada Estado, al instituir las potestades y privilegios de la Administración Pública, garantice que estas no atenten contra el aseguramiento y defensa de los derechos humanos; en tanto estos se constituyen en fin y límites constitucionales del ejercicio del poder estatal. Asimismo, se realiza un análisis, en la vigente normativa tributaria cubana, a uno de los más reconocidos privilegios administrativos: el solve et repete o pago previo, poniéndose de manifiesto la necesidad de su eliminación ante las consecuencias que su exigencia genera en el ámbito de la protección de los derechos del obligado tributario.

La eficacia de los derechos sociales en el siglo XX mexicano
Authors: Sancliment Martínez Julio Eduardo
Published: January 2020

En México, los derechos sociales han tenido diversas naturalezas jurídicas desde su aparición en el texto constitucional de Querétaro. Así las cosas, mientras el entendimiento de éstos no representó mayor problema —sobre todo económico— para el gobierno —ya que pareciera que no se les considerara derechos subjetivos de las personas—, el Constituyente estuvo en posibilidad de adicionar diversas cláusulas sociales buscando fundamentalmente la legitimación del poder público. El entender el desarrollo de la naturaleza jurídica de los derechos sociales en México, resulta imprescindible para abordar el “cambio de paradigma” regido por una visión totalmente normativa que trajo la reforma de junio de 2011.
Do “sistema das artes” à ambiência pós-histórica: itinerários da estética contemporânea
Authors: Duarte Rodrigo
Published: January 2020

Uma fonte importante da reflexão sobre estética, hoje, é o que Hegel denominou “sistema das artes”, a saber, o resultado de um processo dialético no qual os principais métiers artísticos – começando com a arquitetura e terminando na poesia – se relacionam entre si, levando em consideração suas características associadas com o espaço ou com o tempo, originando uma espécie de “ranking” das artes. A estética contemporânea propriamente dita encontra na discussão de Theodor Adorno sobre o que ele chama de “pseudomorfose” um dos ecos mais influentes da posição de Hegel. Na medida em que as afirmações de Adorno foram desenvolvidas e atualizadas rumo à sua noção tardia de Verfransung (imbricação) das artes, elas se tornaram comensuráveis com a concepção de Arthur Danto de uma situação pós-histórica – um ambiente no qual nenhum ramo artístico predomina sobre qualquer outro, ocorrendo outrossim ilimitadas possibilidades de hibridização entre as artes. O ponto de vista de Danto, por sua vez, sugere uma proximidade com o diagnóstico de Vilém Flusser, de que presenciamos um ambiente pós-histórico num sentido mais amplo, dominado pelo que ele chama de “imagens técnicas”, no qual a arte aparece como um tipo de embriaguez.
Sobre “A arte da crítica” e a “estética aplicada”
Authors: Barros Oliveira Bernardo
Published: January 2020

Comentário do texto da palestra de Patrick Pessoa, intitulado “A arte da crítica”. Neste comentário procuramos abordar como o texto em questão nos levou a pensar como o discurso teórico deve ser visto em si mesmo enquanto opção estética, e não como modo natural de expor teses; como um elemento expressivo, e não como mero condutor neutro de ideias. Para tanto, nos utilizamos da noção benjaminiana de “ironia formal” para localizar o cerne da maneira particular com que o referido texto é construído.
Tudo sendo dado: sobre imagens readymades, espelhos e triangulações
Authors: Lage Mariana
Published: January 2020

O presente artigo trabalha com a perspectiva da arte como espelho transformador das consciências, como defendido por Arthur Danto, em diálogo com a análise de Jacques Leenhardt sobre a obra “Etant Donnés”, de Marcel Duchamp, a fim de pensar, em última instância, se a própria realidade poderia funcionar como um espelho, uma vez que habitamos um momento histórico em que a distinção entre arte e realidade perdeu sua evidência e em que estamos submersos em reflexos (selfies e black mirrors) e imagens clichês (imagens readymades) em excesso.

Factors that are associated with the development of acute respiratory infections in the kindergarten - an analysis of the population of 1,528 children
Authors: Tasic Radica , Kekus Divna , Rosic Natasa
Published: January 2020

Introduction/Objective. Acute respiratory infections (ARI) are very common amongst children attending preschool institutions (PIs) and they represent a significant public health problem. Strict compliance with the legal regulations should reduce the incidence of respiratory infections in children. The aim of this research was to determine predictors for the appearance of ARI in kindergarten. Methods. The research was conducted as a cross-sectional study at the six PIs located on the territory of Vozdovac municipality during a six-month period (from January to June 2016). The target population consisted of 1,528 children who were between three and seven years old. Data analysis was done using descriptive statistics (?2 test and Spearman?s rank correlation coefficient). Results The increase in the number of children for 30% above the norm was a predictive factor for the increase of respiratory infections (p < 0.001). Sex differences were not a predictive factor for the emergence of respiratory infections in any age group. In all organizational units, March was the period when respiratory infections were on the increase (37.2%, p < 0.001), and it was significantly higher (p < 0.001) in cases, when the diseased child had a brother and/or a sister in the same kindergarten. During the observed period, the number of teachers corresponded to the range of one educator per 12 to 19 children. A constant number of educators could not reduce the incidence of respiratory infections, especially during the February?March period (p < 0.001). Conclusion. In addition to active treatment and strict compliance with the legal regulations in the organization of PIs, the reduction in incidence of respiratory infections in preschool children could be achieved if the number of enrolled children complied with the standard, as well as by preventive procedures in children?s groups: avoiding overheated and dry air, regular ventilation, fresh air, well-planned diet, physical activity, personal hygiene and cleanliness.

Introduction/Objective. Since tibial shaft is a common location of opened and closed tibial fractures, it is very important to determine the best method of treating these fractures. Our objective was to assess whether the Ilizarov technique is appropriate in terms of complications, outcomes, and pain reduction in treatment of patients with tibial shaft fracture. Methods. Retrospective analysis included all consecutive patients with tibial shaft fracture treated with the Ilizarov technique in the period from January 2013 to June 2017 at the Banjica Institute for Orthopaedic Surgery, Belgrade, Serbia. Demographic and clinical data on patients were collected. Pain was assessed using visual analogue scale of pain. Two models of uni- and multi-variate linear regression analysis were performed. Results. The study showed that the overall rate of complications was low, and that hypertension, administration of antibiotics, and reoperation prolonged fixation. Also, severe fractures and longer procedure time delay mobilization. Significant reduction of pain was observed. Conclusion. The Ilizarov technique is a safe and reliable method in the treatment of patients with tibial shaft fractures and is followed by pain reduction, overall improvement of functioning, good outcomes, and is not commonly associated with complications.
Adoption of computer particle swarm optimization algorithm under thermodynamic motion mechanism
Authors: Li Qizhong , Yue Yizheng , Wang Zhongqi
Published: January 2020

In order to improve the stability and sensitivity of particle swarm optimization (PSO) algorithm and to solve the problem of premature convergence, in this re-search, a computer PSO algorithm based on thermodynamic motion mechanism is proposed based on the principle of thermodynamic motion mechanism. Firstly, the thermodynamic motion phenomenon, the diffusion law in kinematics and the standard PSO algorithm are introduced. Then, according to the basic idea of thermodynamic motion mechanism, the standardized PSO algorithm is optimized and its optimization process is introduced. Finally, the experimental results are analysed by setting the test function. The results show that among the five test functions, the computer PSO algorithm based on thermodynamic motion mechanism has a higher probability of jumping out of the local optimal solution. Its robustness and stability are much better than standard PSO algorithms. The evolution ability of the computer PSO algorithm based on thermodynamic motion mechanism is better than that of the standard PSO algorithm. The standard PSO algorithm is superior because it is based on thermodynamic motion mechanism. The research in this paper can provide good guidance for improving the performance of PSO algorithm.

Authors: Tian Shujian , Li Guozhuang , Liu Jun , Yuan Haoyun , Song Xiaoyong , Wang Weishu
Published: January 2020

The heat transfer performance of the spent fuel transport cask is inseparably related to the safety of the whole reprocessing system. In this study, we carried out the thermal analysis on the NAC-STC transport cask for AP1000 spent fuel assembly to evaluate the thermal performance of transport cask by the finite element method software ANSYS. A computational dynamics model was developed to study the temperature distribution inside the transport cask and on the surface of the cask. The effectiveness of the numerical calculation is demonstrated by comparing with the theoretical results. The results show that transport cask can reach steady-state during transportation, and the highest temperature in the case is 328?, which is below the maximum safety limit of 400?. Besides, the temperature of the fuel element baskets, sealing ring, photon shielding layer and neutron shielding layer in the cask are all within the safety limit.

Llywarch Hen’s Dyke: Place and Narrative in Early Medieval Wales
Authors: Seaman Andy
Published: January 2020

Dykes must have been important features within the early medieval landscape, but scarcely attract more than cursory discussion in archaeological literature focused on Wales and western Britain. Analysis of a dyke recorded in a boundary clause attached to an eighth century charter in the Book of Llandaff demonstrates how a multidisciplinary approach can garner new insights into the function and significance of dykes in the early medieval landscape. Llywarch Hen’s Dyke defined a large part of the bounds of Llan-gors, a royal estate in the kingdom of Brycheiniog. On the ground the dyke is represent by a prominent agricultural land boundary, but the monument also operated as a ‘mnemonic peg’ through which oral traditions associated with power and place were narrated.
The Danevirke: Preliminary Results of New Excavations (2010–2014) at the Defensive System in the German-Danish Borderland
Authors: Tummuscheit Astrid , Witte Frauke
Published: January 2020

Between 2010 and 2014, the State Archaeological Department of Schleswig-Holstein in Germany jointly undertook excavation work with the Danish Museum Sønderjylland – Arkæologi Haderslev on the linear earthwork monument, the Danevirke. These transnational excavations have led to important new findings, which include the discovery of the site of a gateway, where major transport routes converged for at least five hundred years. Furthermore, newly gained C14-dates indicate that the second main building phase of the Danevirke dates to around AD 500. Therefore, the dating of the first beginnings of the earthwork must be pushed back in time, making the Danevirke more than 200 years older than previously thought. Additionally, dendrochronological dates show that around the year AD 1200 substantial building activities took place, which reveal the intention of developing the Danevirke further. A project is currently ongoing, which aims to publish the results of the 2010−2014 excavations. This article outlines the synopsis of those results and current working hypotheses.

Published: January 2020

Eel is one of the fisheries commodity that have not been rearing widelyin Indonesia. Constraint that occured in rearing eel is slow growth. A way to accelerate eel growth isfeeding with enrichment by using an amino acids. An amino acids can be used directly by eel for cell growth and the formation of body tissue. An amino acid that is used from the stingrays are not utilized by people  because it has no economic value to production activities. This research was aimed to study the growth rate of eel whichis fed with enrichment of an amino acids derived from stingray extract. The method in this research used completely randomized design (CRD) with 3 treatments and 3 replications. The measure of eel that usedare 26-28 cm, the average weight is 28 grams and an amino acids dosage that used are 0 ml, 0.5 ml and 1 ml. It use FR 3% which is given at night to support the characteristic of eel that is nocturnal (active at night). The analyze result from the parameters that have been observed, there is not a significant effect (P> 0.05) and the fed with enrichment by using an amino acids with the dosage used hasn't been able to be utilized as fish feed mixture to increase growth rate.

Each diet is randomly assigned to the triplicate aquarium and fed to fish three times a day up to satiation for 4 weeks. The results showed that fermented leucaena leaves treatments were significantly higher (P<0.05) than that control in final weight and feed conversion rasio. Nutrients digestibility and final weight were significantly highest (P<0.05) in fermented leucaena leaves with A. niger compared to the other treatment. The value of protein digestibility was significantly highest (P<0.05) in fermented leucaena leaves with A. niger (76,04%), followed by fermented leucaena leaves S. cerevisiae with (69,71%), fermented leucaena leaves meal with R. oligosporus (68,24%), and control (65,18). Leucaena leaves had no effect on physiological processes in catfish, as shown by hematological parameter values that were within the normal range.

Oodev hormone application has been applied to stimulate gonadal maturity so that fish fry could be available outside the spawning season. This research aimed to study the effect of Oodev hormone on the gonadal maturity of asian redtail catfish Hemibagrus nemurus (Valenciennes, 1840). This research method used a completely randomized design (CRD) with 4 doses treatments, i.e 0, 0,25, 0,50, 1,00 ml/kg. A total of 8 fish were used as replications for each treatment. The parameters measured were the gonado somatic index (GSI) and egg diameter. The results showed that the effect of Oodev hormone on GSI and egg diameter was significantly different (P<0.05). A higher Oodev hormone dose caused an increase of GSI and egg diameter size. The recommended Oodev dose for application is 1 ml/kg.
KONSEP PENDIDIKAN IKHWAN AL-SHAFA DAN RELEVANSINYA DENGAN DUNIA POSTMODERN
Authors: Afandi Rahman
Published: January 2020

Abstract: The Ikhwan al-Shafa is an organization established by a group of people (mujtahidin) consisting of philosophers, who focused their attention on the field of da'wah and education, that developed at the end of the second century Hijrah in the city of Basra, Iraq. It is a discussion and teaching forum. In general, its emergence is motivated by concerns about the implementation of Islamic teachings that have been contaminated by teachings from outside Islam at that time, and to revive love for science among Muslims. They compiled 51 agreements known as the "Rasail Ikhwan al-Shafa" (Ikhwan al-Shafa agreement). The background of Rasail Ikhwan al-Shafa writing came from dissatisfaction with the implementation of the Islamic education and lifestyle at that time. This organization viewed education with a rational and empirical view, or a combination of intellectual and factual views. They viewed science as a description of something that could be known in nature, the knowledge produced by human thought occurs because it receives information materials sent by the five senses. Some of the Ikhwan al-Shafa's concepts or thoughts about education have an urgent relevance to education that is applied in the current postmodern era. Whether it's how to get knowledge, teacher competency standards, goals, curriculum and methods that are used.

Published: January 2020

Introduction

Primary care providers have a role to play in supporting the development of healthy eating habits, particularly in a child’s early years. This study examined the feasibility of implementing the NutriSTEP® screen—a 17-item nutrition risk screening tool validated for use with both toddler and preschooler populations—integrated with an electronic medical record (EMR) in primary care practices in Ontario, Canada, to inform primary care decision-making and public health surveillance.

Methods

Five primary care practices implemented the NutriSTEP screen as a standardized form into their EMRs. To understand practitioners’ experiences with delivery and assess factors associated with successful implementation, we conducted semi-structured qualitative interviews with primary care providers who were most knowledgeable about NutriSTEP implementation at their site. We assessed the quality of the extracted patient EMR data by determining the number of fully completed NutriSTEP screens and documented growth measurements of children.

Results

Primary care practices implemented the NutriSTEP screen as part of a variety of routine clinical contacts; specific data collection processes varied by site. Valid NutriSTEP screen data were captured in the EMRs of 80% of primary care practices. Approximately 90% of records had valid NutriSTEP screen completions and 70% of records had both valid NutriSTEP screen completions and valid growth measurements.

Conclusion

Integration of NutriSTEP as a standardized EMR form is feasible in primary care practices, although implementation varied in our study. The application of EMR-integrated NutriSTEP screening as part of a comprehensive childhood healthy weights surveillance system warrants further exploration.
Using a Multi - function Pressure Valve in Volumetric Hydraulics Drives
Authors: Efremova K. D. , Pilgunov V. N.
Published: January 2020

The paper deals with using hydraulic equipment for pressure and flow control in volumetric hydraulic drives to control a throttle movement speed of the output link of an executive hydraulic motor. Depending on the type of problem to be solved, hydraulic equipment is divided into the pressure and flow control, and the shutoff and regulating elements used in equipment are divided into those of valve and spool type. The main paper objective is to analyse designs and feasibilities for using a multi-functional pressure valve to solve real-life problems of control in a volumetric hydraulic drive. The paper presents a multi-function indirect pressure valve design of DZ standard size (Rezroth Bosch Group) and its detailed principle of operation. In the multifunctional pressure valve design there are threaded plugs, the combination of which allows us to control the pilot valve, using the pressure in the hydraulic system (internal control) or the pilot valve control from an external pressure source. Pilot drainage to the valve outlet port (internal drainage) or drainage directly to the tank is possible. It is shown that the term “Load Sensing System” that is used in Western equipment to mean “control based on load magnitude” can be correctly used to describe designs for using a multifunctional valve.

Issues on setting up internal functional communications of the valve to select feed modes of a pilot valve and its drainage have been fully considered. By examples of using a multifunctional pressure valve, the valve operation capabilities are shown, namely as an overflow valve, a sequence one, its operation in the balancing scheme of the gravity load and as part of a hydraulic drive with alternating load. The use of multi-function pressure valve in presses allows us to increase the pressing force through using the weight of the punch. The article belongs to the category of systems engineering, and the represented options of the using valve can be applied when designing the volumetric hydraulic drives with throttle control of the movement speed of the output link in hydraulic drives.

Published: January 2020

The paper discusses current trends in the Russian labor market. The question of the importance of communication and self-presentation skills for a modern young engineer is highlighted. The paper provides a definition of the engineering elite as universal specialists capable of solving diverse problems. An important component of the education of the elite is the stressful situation simulation for the development of skills for solving extraordinary tasks and teamwork. A visit to the forum is an important component of the training, in which students learn to apply the learned skills in practice to consolidate them and broaden outlook. The necessity of attending high-level public events for students striving for self-realization not only as specialists, but also as an educated person, is shown.
On Linear Independence of Some Functions
Authors: Ivankov P. L.
Published: January 2020

To study an arithmetic nature of the values of hyper-geometric functions (and their derivatives including those with respect to parameter), it is common practice to use one either Siegel's method or the method based on the effective construction of the linear approximating form. The main distinction between these methods consists in the mode of construction of the first approximating form. Applying Siegel's method allows us to construct such a form by means of a pigeonhole principle that makes it possible to establish, in certain cases, the algebraic independence of the values of corresponding functions. The Siegel's method can be usually applied just while considering hyper-geometric functions with rational parameters. The effective method has a certain advantage here, for in some cases this method enables us to carry out corresponding investigation also for the functions with irrational parameters. Another advantage of the effective method is that it provides obtaining of high- accuracy quantitative results. By quantitative results one usually implies the estimates of the moduli of the linear forms in the values of corresponding functions. The effective method has made it possible to obtain, in some cases, estimates being precise regarding the height of such forms with calculation of the corresponding constants. A drawback of the effective method is the narrow domain of its applications. The effective construction of the linear approximating form, which initiates reasoning, is always a challenge. So far, an effective construction of the approximating form for the product of powers of hyper-geometric functions (with the rare exceptions) failed.

In both aforementioned methods one proves previously linear independence (in Siegel's method, as a rule, algebraic independence,) of the functions under consideration. Such a proof is often considered as an independent result.

In this paper, by means of the method especially elaborated for this purpose we establish linear independence of some hyper-geometric functions and their derivatives (including those with respect to parameter) over the field of rational fractions. Subsequently, it will be possible to apply this result to investigate arithmetic properties of the values of such functions. Herewith we mean the application of the effective method to achieve the sufficiently accurate quantitative result.
