Authors: Alves Larissa da Silva Ferreira , Freitas Carla Camila Gomes
Published: May 2021

A implantação de políticas educacionais que ampliaram cursos e interiorizaram instituições de nível técnico e superior pelo Brasil foi um serviço constituído em vários pontos do país, e acabou sendo um fenômeno que tem chamado a atenção de estudos nos últimos anos. Este artigo tem como objetivo compreender novas dinâmicas territoriais fomentadas por políticas educacionais que implantaram e expandiram cursos nas seguintes instituições de ensino localizadas no município de Pau dos Ferros, Semiárido do estado do Rio Grande do Norte: Universidade do Estado do Rio Grande do Norte (UERN), Universidade Federal Rural do Semiárido (UFERSA) e Instituto Federal de Educação, Ciência e Tecnologia do Rio Grande do Norte (IFRN). Para tanto, foi necessária uma busca de dados secundários, disponíveis em sites como o do Ministério da Educação (MEC), do Instituto Brasileiro de Geografia e Estatística (IBGE), bem como nas próprias instituições de ensino aqui estudadas em relação aos dados de matrículas. Concluiu-se que os cursos de graduação e de pós-graduação disponibilizados por essas instituições foram criados entre os anos de 2004 e 2015. Nesse período foram implantados 14 novos cursos de graduação, nas três instituições federais de ensino superior (IFES) e 04 cursos de pós-graduação na UERN, ampliando, assim, a dinâmica urbano-regional de Pau dos Ferros no contexto da hinterlândia regional semiárida, sendo o Semiárido um território historicamente desprovido desses serviços.

Authors: Alkhotani Amal , Abualula Hanadi , Almatrafi Yasser , Ghomiem Sawsan , Alaa Alkhotani
Published: May 2021

Background:

Lacosamide is characterized by its novel dual mode of action on account
of its structural components; its molecule contains a functional amino acid that selectively and
slowly promotes the inactivation of voltage-gated sodium channels.

Objective:

This study aims to assess the effectiveness and tolerability of Lacosamide with respect
to its use in the treatment of focal epileptic patients.

Methods:

This retrospective cohort study used data collected from the clinical notes or diaries of
all epileptic patients who were treated in King Abdullah Medical City during the time period from
2014 to 2019. The multivariate Generalized Estimating Equation (GEE) repeated measure logistic
regression analysis was used to assess the odds of having an improvised seizure rate.

Results:

Majority of the focal epileptic patients (57.9%) were diagnosed with temporal epilepsy,
while 26.3% patients had frontal epileptic lesion/diagnoses. Majority of the patients (54.4%) had received
a combination of old and new treatment. Out of the seven patients who reported side effects,
57.14% experienced dizziness and headache, tremors (n = 1), loss of balance (n = 1) and increased
seizure with abnormal vision acuity and psychosis (n = 1). 84.2% patients experienced reduced median
seizure frequency in 12-month period. However, on the basis of clinical characteristics, no significant
difference was observed in the seizure control rate. No statistically significant differences
were observed between male and female patients with respect to their average improvement rate
across the four time points.

Conclusion:

Lacosamide is an effective and well tolerable drug for patients with focal epilepsy.
English and uzbek toponymic phraseological units: Linguocultural and historical aspects
Authors: Xudoyorova Safura
Published: May 2021

The present paper is devoted to investigation of English and Uzbek phraseological units which contain place names in their structure. An attempt is made to find out the sources of origin as well as to analyze them from linguocultural point of view. Toponymic phraseological units in both languages are classified into five main groups according to the emergence sources and particular attention is given to the historically associated phraseological units. Here the phraseological units that are based on the exact historical events and facts are discovered and explained. The author proposes two major groups of phraseological units concerning the existence of real place names in their structure. There are also revealed properties of real toponyms that stimulated the connection in the meaning of a proper name and a phraseological unit. Additional connotation of toponyms which influenced on the meaning of phraseological units are also discovered. The examples are taken from several  English and Uzbek phraseological and paremiological dictionaries. The examples are analyzed by descriptive and comparative methods. Similarities and differences are found out due to national-cultural specifics of both languages.

Een vijfjarige Duitse warmbloedhengst die chronisch mank was ten gevolge van een degeneratieve aandoening in het kroongewricht en die geen verbetering vertoonde na conservatieve therapieën, werd behandeld met autologe mesenchymale stamcellen (MSC). Deze MSC werden geïsoleerd uit het perifeer bloed van de patiënt en 2,5 miljoen van deze cellen werden in het gewricht geïnjecteerd, tweemaal met een interval van acht weken. De positieve evolutie na behandeling werd gedocumenteerd aan de hand van een klinische evaluatie en objectieve drukplaatanalysen. In dit artikel wordt voor de eerste maal het gebruik van perifeer bloed beschreven als bron van MSC voor het behandelen van een degeneratieve gewrichtsaandoening bij een paard.

Published: May 2021

Een mannelijke, gecastreerde Europese korthaar van 10 jaar werd aangeboden met huidklachten. Schilfering, alopecie en jeukgedrag waren aanwezig. Het dermatopathologisch onderzoek toonde een interface dermatitis met een gering aantal apoptotische keratinocyten, een murale lymfocytaire folliculitis en de afwezigheid van sebumklieren. Deze huidveranderingen kunnen voorkomen als een paraneoplastisch syndroom veroorzaakt door een thymoma. Radiografie van de borstholte bevestigde de aanwezigheid van een massa in het craniale mediastinum. Via een sternale thoracotomie werden een grote tumor en twee kleine gezwellen verwijderd. Histopathologisch onderzoek van de massa’s toonde aan dat het wel degelijk ging om lymfocytrijk thymoma. De kat vertoonde een snelle en sterke verbetering van de huidletsels. Twee maanden postoperatief was er een heropflakkering van de exfoliatieve dermatitis die in regressie werd gebracht met een dexamethasonekuur. Tijdens de laatste follow-up, 6 maanden postoperatief, vertoonde de kat nog slechts geringe schilfering en was hij volledig jeukvrij zonder medicatie.
Knelpunten in aquacultuur: enkele risicovolle aspecten van de vroege levensstadia van de vis
Authors: Verhaegen B. , Rekecki A. , Decostere A. , Van den Broeck W.
Published: May 2021

Aquacultuur is een zeer snel groeiende sector, maar er zijn nog talrijke knelpunten bij het opkweken van larven (larvicultuur) en van adulte vissen. Veel van deze knelpunten zijn van nutritionele aard. Het voedingsregime is nog vaak onvoldoende afgesteld op de behoeften van specifieke vissoorten waardoor uithongering een grote invloed blijft hebben. Deze problemen kunnen opgelost worden door de ontwikkeling van het gastro-intestinale stelsel per vissoort in kaart te brengen. Parameters, zoals de enterocytenhoogte, de aanwezigheid van supranucleaire vacuoles in de enterocyten en ‘the point of no return’ kunnen als maatstaf gebruikt worden om uithongering te monitoren en te voorkomen. Aan de hand van deze gegevens kan een optimaal voedingsregime met rotiferen (radardiertjes), Artemia (pekelkreeftjes) en Copepoda (eenoogkreeftjes) uitgewerkt worden.

Published: May 2021

Voor het eerst werd een uitbraak van hondenziekte waargenomen bij steenmarters (Martes foina) in het oostelijk deel van Vlaanderen. De klinische en pathologische bevindingen waren gelijklopend met andere uitbraken beschreven bij marterachtigen in Europa. Door middel van reverse transcriptase polymerase chain reaction werd morbillivirus RNA gedetecteerd in een orgaanhomogenaat geïnoculeerd op Vero.DogSLAM-cellen. Het virus werd gesequeneerd en geïdentificeerd als een hondenziektevirusstam, honderd procent identiek aan een eerder geïsoleerd virus uit een marter uit Duitsland. Na een periode van quasi afwezigheid van steenmarters in Vlaanderen door intense vervolging is hun populatiedichtheid in de laatste decennia beduidend toegenomen. Hoewel de onderliggende mechanismen van de waargenomen populatieveranderingen onduidelijk zijn, wijzen onze bevindingen op een spreiding van hondenziektevirus vanuit centraal Europa volgend op dispersie van steenmarters. Verdere spreiding zou een negatieve impact kunnen hebben voor de sterk bedreigde boommarter (Martes martes) en de teruglopende bunzing (Mustela putorius) populatie in Vlaanderen.
Een alternatief voor de ventilatie van één long tijdens thoracotomie bij een volwassen paard

Om één long van een volwassen paard te kunnen ventileren tijdens de anesthesie voor een thoracoscopie en exploratieve thoracotomie, werd met behulp van een zelfgemaakte endobronchiale blocker een andere dan de gerapporteerde technieken ontwikkeld. Een opening met een diameter van 1 cm werd gemaakt 15 cm distaal van het proximale uiteinde van een standaard 28 mm ID endotracheale tube (ETT), waar een broncho-alveolaire katheter kon doorgeschoven worden. Na inductie van de anesthesie werd de aangepaste ETT opgeschoven tot aan de larynx. Vóór de intubatie van de trachea werd de broncho-alveolaire katheter opgeschoven door de ETT en onder endoscopische begeleiding in de linkerhoofdbronchus geplaatst. Alhoewel dit niet nodig bleek tijdens de chirurgische ingreep, zou het volstaan hebben de cuff van de broncho-alveolaire katheter op te blazen om op de ventilatie van één long over te schakelen.

Published: May 2021

The amplification of electromagnetic terahertz radiation in a structure with two layers of hydrodynamic graphene with a direct electric current is studied theoretically. The hydrodynamic conductivity of graphene is investigated. It is shown that the real part of the graphene conductivity can be negative in the terahertz frequency range at the drift velocities of charge carriers in graphene that are lower than the phase velocity of the electromagnetic wave. For small wavevectors of a terahertz wave incident on a graphene structure, the spatial dispersion insignificantly contributes to the hydrodynamic graphene conductivity. Because of this, the amplification efficiency does not depend on the direction of currents in each of the graphene layers. It is shown that graphene with direct electric current can be used to create THz amplifiers operating at room temperature.

Published: May 2021

Background

Inflammatory arthritides (IA) such as rheumatoid arthritis or psoriatic arthritis are disorders that can be difficult to comprehend for health professionals and students in terms of the heterogeneity of clinical symptoms and pathologies. New didactic approaches using innovative technologies such as virtual reality (VR) apps could be helpful to demonstrate disease manifestations as well as joint pathologies in a more comprehensive manner. However, the potential of using a VR education concept in IA has not yet been evaluated.

Objective

We evaluated the feasibility of a VR app to educate health care professionals and medical students about IA.

Methods

We developed a VR app using data from IA patients as well as 2D and 3D-visualized pathological joints from X-ray and computed tomography–generated images. This VR app (Rheumality) allows the user to interact with representative arthritic joint and bone pathologies of patients with IA. In a consensus meeting, an online questionnaire was designed to collect basic demographic data (age, sex); profession of the participants; and their feedback on the general impression, knowledge gain, and potential areas of application of the VR app. The VR app was subsequently tested and evaluated by health care professionals (physicians, researchers, and other professionals) and medical students at predefined events (two annual rheumatology conferences and academic teaching seminars at two sites in Germany). To explore associations between categorical variables, the χ2 or Fisher test was used as appropriate. Two-sided P values ≤.05 were regarded as significant.

Results

A total of 125 individuals participated in this study. Among them, 56% of the participants identified as female, 43% identified as male, and 1% identified as nonbinary; 59% of the participants were 18-30 years of age, 18% were 31-40 years old, 10% were 41-50 years old, 8% were 51-60 years old, and 5% were 61-70 years old. The participants (N=125) rated the VR app as excellent, with a mean rating of 9.0 (SD 1.2) out of 10, and many participants would recommend use of the app, with a mean recommendation score of 3.2 (SD 1.1) out of 4. A large majority (120/125, 96.0%) stated that the presentation of pathological bone formation improves understanding of the disease. We did not find any association between participant characteristics and evaluation of the VR experience or recommendation scores.

Conclusions

The data show that IA-targeting innovative teaching approaches based on VR technology are feasible.
Wearable Bioimpedance Monitoring: Viewpoint for Application in Chronic Conditions (Preprint)
Authors: Groenendaal Willemijn , Lee Seulki , van Hoof Chris
Published: May 2021

UNSTRUCTURED

Currently, nearly 6 in 10 US adults are suffering from at least one chronic condition. Wearable technology could help in controlling the health care costs by remote monitoring and early detection of disease worsening. However, in recent years, there have been disappointments in wearable technology with respect to reliability, lack of feedback, or lack of user comfort. One of the promising sensor techniques for wearable monitoring of chronic disease is bioimpedance, which is a noninvasive, versatile sensing method that can be applied in different ways to extract a wide range of health care parameters. Due to the changes in impedance caused by either breathing or blood flow, time-varying signals such as respiration and cardiac output can be obtained with bioimpedance. A second application area is related to body composition and fluid status (eg, pulmonary congestion monitoring in patients with heart failure). Finally, bioimpedance can be used for continuous and real-time imaging (eg, during mechanical ventilation). In this viewpoint, we evaluate the use of wearable bioimpedance monitoring for application in chronic conditions, focusing on the current status, recent improvements, and challenges that still need to be tackled.

Exposure to a reduction in ambient pressure such as in high-altitude climbing, flying in aircrafts, and decompression from underwater diving results in circulating vascular gas bubbles (i.e., venous gas emboli [VGE]). Incidence and severity of VGE, in part, can objectively quantify decompression stress and risk of decompression sickness (DCS) which is typically mitigated by adherence to decompression schedules. However, dives conducted at altitude challenge recommendations for decompression schedules which are limited to exposures of 10,000 feet in the U.S. Navy Diving Manual (Rev. 7). Therefore, in an ancillary analysis within a larger study, we assessed the evolution of VGE for two hours post-dive using echocardiography following simulated altitude dives at 12,000 feet. Ten divers completed two dives to 66 fsw (equivalent to 110 fsw at sea level by the cross correction method) for 30 minutes in a hyperbaric chamber. All dives were completed following a 60-minute exposure at 12,000 feet. Following the dive, the chamber was decompressed back to altitude for two hours. Echocardiograph measurements were performed every 20 minutes post-dive. Bubbles were counted and graded using the Germonpré and Eftedal and Brubakk method, respectively. No diver presented with symptoms of DCS following the dive or two hours post-dive at altitude. Despite inter- and intra-diver variability of VGE grade following the dives, the majority (11/20 dives) presented a peak VGE Grade 0, three VGE Grade 1, one VGE Grade 2, four VGE Grade 3, and one VGE Grade 4. Using the cross correction method for a 66-fsw dive at 12,000 feet of altitude resulted in a relatively low decompression stress and no cases of DCS.

Published: May 2021

Promiscuous activities have been related to the capacity to catalyze
reactions different from those a protein has evolved to sustain. From
this evolutionary perspective, we rethought the serum albumins
promiscuous behavior. We found that the cross aldol condensation of
acetone and p-formylbenzonitrile is a promiscuous reaction conserved in
humans and other mammals. Structural and evolutionary analysis indicates
that the involved residues could have evolved for a still unknown
biological function. Our results could contribute to better characterize
the serum albumin family and raise questions about the evolution of
protein promiscuity and function.

Published: May 2021

Introduction:Community-acquired pneumonia(CAP) in children has tended to
decrease in recent years with effective vaccination and
treatments.However,the frequency of complicated community-acquired
pneumonia (CCAP) is gradually increasing.By determining risk factors for
the development of CCAP,new approaches for early diagnosis and effective
treatment can be determined. Method: Records of 113 patients who were
hospitalized due to CAP and CCAP between January 2017 and December 2017
were examined.Demographic characteristics of the patients,comorbid
diseases,admission symptoms,physical examination findings,laboratory and
imaging results, treatments, hospital stay and treatment response were
recorded. Pleural effusion,if empyema developed in patients with
CCAP,thoracentesis and/or chest tube insertion,fibrinolytic therapy,and
the need for additional surgical intervention were investigated.
Results:Our patients had a mean age of 3.6 ± 2.2, 60(53%) were female
and 53(47%) were male.93 (82.3%) of the patients were diagnosed with
CAP and 18(15.9%) were diagnosed with CCAP.Detection of pleural
effusion at the admission of patients in multivariate logistic
regression[(OR (95% CI),4.24 (1.77-10.16), p <0.001)]
respiratory distress(tachypnea and retraction)[(OR (95% CI) 3.04
(1.30-7.130) ),p <0.001)] and hypoxia (92% and less saO2
measured by pulse oximeter) at admission [(OR (95% CI),: 5.247
(1.58-9.46),p <0.001)] were identified as independent risk
factors for diagnosis of CCAP. Discussion:Hypoxia,respiratory distress
and imaging pleural effusion are important distinguishing findings for
development of complications in patients admitted for CAP. Determining
the etiology of CCAPs and early diagnosis and treatment approaches can
be established, and protection measures can be taken. With future
prospective studies, the causes of CCAP can be determined and preventive
measures and new treatment approaches can be developed

Published: May 2021

A novel numerical computing framework through Lobatto IIIA method is presented for the dynamical investigation of nanofluidic problem with Williamson fluid flow on a stretching sheet by considering the thermal slip and velocity. The impact of thermophoresis and Brownian motion on phenomena of heat transfer are explored by using Buongiorno model. The governing non-linear partial differential system representing the mathematical model of the Williamson fluid is transformed in to a system of ODE by incorporating the competency of non-dimensional similarity variables. The dynamics of the transformed system of ODE are evaluated through the Lobatto IIIA numerically. Sufficient graphical and numerical illustrations are portrayed in order to investigate and analyze the influence of physical parameters: Williamson parameter, Prandtl number, Lewis number, Schmidt number, ratio of diffusivity parameter, ratio of heat capacitance parameter on velocity, temperature, and concentration fields. The numerically computed values of local Nusselt number, local Sherwood number, and skin friction coefficient are also inspected for exhaustive assessment. Moreover, the accuracy, efficiency and stability of the proposed method is analyzed through relative errors.
Research on heat transfer characteristics and borehole field layout of ground heat exchangers to alleviate thermal accumulation with groundwater advection
Authors: Sun Zhongcheng , He Zhixia , Yu Mingzhi
Published: May 2021

The heat transfer performance of ground heat exchanger is significant to the ground source heat pump. The soil thermal parameters, the groundwater advection and the different borehole field layout are important factors to affect the performance of ground heat exchanger. Therefore, the influence of groundwater advection velocity, soil physical parameters and different borehole field layout on the soil temperature distribution and evolution around the ground heat exchanger has been analyzed and studied with unbalanced seasonal thermal load based on the moving finite line heat source model with groundwater advection. The results show that the heat accumulation is easy to occur as the time develops when the groundwater advection is taken into consideration. No matter what type of geological condition is employed, a reasonable borehole field layout can effectively avoid heat accumulation problems under the condition of keeping the same amount boreholes without changing the original ground area. The borehole field layout dispersed along the center line of the advection and concentrated in the advection downstream relatively can effectively reduce the heat accumulation.
A computational method to solve for the heat conduction temperature field based on data-driven approach
Authors: Li Kun , Shan Shiquan , Zhang Qi , Cai Xichuan , Zhou Zhijun
Published: May 2021

In this paper, a computational method for solving for the 1-D heat conduction temperature field is proposed based on a data-driven approach. The traditional numerical solution requires algebraic processing of the heat conduction differential equations, and necessitates the use of a complex mathematical derivation process to solve for the temperature field. In this paper, a temperature field solution model called hidden temperature method is proposed. This model uses an artificial neural network to establish the correspondence relationship of the node temperature values during the iterative process, so as to obtain the ?Data to Data? solution. In this work, one example of 1-D steady-state and three examples of 1-D transient state are selected, and the calculated values are compared to those obtained by traditional numerical methods. The mean-absolute error of the steady-state is only 0.2508, and among the three transient cases, the maximum mean-square error is only 2.6875, indicating that the model is highly accurate in both steady-state and transient conditions. This shows that the hidden temperature method simulation can be applied to the solution of the heat conduction temperature field. This study provides a basis for the further optimization of the hidden temperature method algorithm.

Published: May 2021

The influence of friction stir welding parameters on thermo-mechanical behavior of the material during welding is analyzed. An aluminum alloy is considered (Al 2024 T351), and different rotating and welding speeds are applied. The finite element model consists of the working plate (Al alloy), backing plate and welding tool. The influence of the welding conditions on material behavior is taken into account the application of the Johnson-Cook material model. The rotation speed of the tool affects the results. If increased, it contributes to an increase of friction-generated heat intensity. The other component of the generated heat, which stems from the plastic deformation of the material, is negligibly changed. When the welding speed, i.e. tool translation speed, is increased, the intensity of friction-generated heat decreases, while the heat generation due to plastic deforming is becoming more pronounced. Summed, this leads to rather small change of the total generation. The changes of the heat generation influence both the temperature field and reaction force. Also, the inadequate selection of welding parameters resulted in occurrence of the defects (pores) in the model.
The investigation of using phase change material for solar pond insulation
Authors: Bozkurt Ismail
Published: May 2021

Solar ponds are systems that store solar energy in salt water as heat energy. In order to store heat energy for a long time in solar pond, the heat insulation should be done well. In this study, the effect of phase change materials was investigated to improve the insulation of the pond and to store the heat energy for a longer time. The melting temperature is a key parameter in the selection of phase change materials. The temperature distribution of the solar pond was examined and phase change materials with melting temperatures in the range of the pond average temperature ?10?C were selected. Three different phase change materials were used in the walls of the solar pond for insulation. The temperature and enthalpy changes of the system were calculated numerically for a year. The heat storage ratio of the solar pond was determined by using the obtained enthalpy and solar radiation data. Consequently, the heat storage ratio of the pond with glass-wool is maximum 20.95% in July and minimum 7.92% in January. The heat storage ratio of the solar pond which paraffin C18, capric acid and paraffin 44 are used as phase change materials is maximum 32.22%, 34.85%, and 47.81% in December, respectively. It is observed that the appropriate selection of phase change materials is provided a longer storage time for solar ponds.
DISCOURSE AND DISQUALIFICATION
Authors: Thau Tena
Published: May 2021

A commonly expressed sentiment in contemporary political discourse is that bigotry should be disqualifying. In this paper, I consider how this sentiment might be formulated into a more precise moral principle. After identifying problems with several candidate formulations, I suggest the version of the principle that best captures the expression’s intended meaning. I then consider the principle’s justifiability, its value as a decision-procedure, and its power as a discursive act.

Exercise seems to
enhance the beneficial effect of bariatric surgery (RYGB) on insulin resistance.
We hypothesized that skeletal muscle extracellular matrix (ECM) remodeling may underly
these benefits. Women were randomized to either a combined aerobic and resistance exercise
training program following RYGB or standard of care (RYGB). Insulin sensitivity
was assessed by OGTT. Muscle biopsies were obtained at baseline, and 3 and 9
months after surgery and subjected to comprehensive phenotyping, transcriptome
profiling, molecular pathway identification and validation in vitro. Exercise training improved insulin sensitivity beyond
surgery alone (e.g., Matsuda index - RYGB:
+123% vs. RYGB + ET: +325%; P ≤ 0.0001).
ECM remodeling was reduced by surgery alone, with an additive benefit of
surgery and exercise training (e.g.,
collagen I - RYGB: -41% vs. RYGB + ET: -76%; P ≤ 0.0001). Exercise and RYGB had an additive effect on
enhancing insulin sensitivity, but surgery alone did not resolve insulin
resistance and ECM remodeling. We identified candidates modulated by exercise training
that may become therapeutic targets for treating insulin resistance, in
particular, the transforming growth
factor-beta 1/SMAD 2/3 pathway and its antagonist follistatin. Exercise-induced
increases in insulin sensitivity after bariatric surgery are at least partially
mediated by muscle extracellular matrix remodeling.
Evaluación del impacto de la infraestructura física educativa en la educación
Authors: Pacheco Martínez Nancy Jacqueline
Published: May 2021

Esta investigación tuvo como objetivo evaluar las condiciones y el estado actual de la infraestructura física educativa (INFE) y su efecto en la educación a nivel preescolar. Para ello, se concretó un estudio de caso en el que se incluyeron los jardines de niños públicos ubicados en la región central de la República mexicana. Las preguntas formuladas fueron las siguientes: ¿qué relación existe entre la INFE y la educación que en su interior se imparte?, ¿cuánto impacta el estado actual de la INFE en la eficacia de la educación? y ¿qué papel desempeña el cumplimiento normativo de la INFE en dicha relación e impacto en la educación? El estudio desarrollado fue de tipo mixto, ya que se utilizaron técnicas cuantitativas, cualitativas y de carácter multidisplinario. Los instrumentos utilizados fueron la selección de la muestra representativa a través de un proceso aleatorio, la observación no participativa, el levantamiento físico de datos, el soporte fotográfico y el análisis de cumplimiento normativo con base en lo que señalan la Ley General de Educación (LGE, 2019), los reglamentos de construcciones de cada uno de los estados evaluados, las normas oficiales mexicanas de tipo obligatorio y de observancia voluntaria, así como los lineamientos de la Secretaría de Educación Pública (SEP,1921), Manuales de Protección Civil e informes de la Organización para la Organización para la Cooperación y el Desarrollo Económicos (OCDE, 1961).Los resultados indican que el estado físico y el emplazamiento de los centros educativos inciden directamente en el desempeño de los estudiantes, por lo que se debe gestionar la adecuada supervisión por parte de las autoridades y de los mismos usuarios (docentes, administrativos y personal), quienes deben identificar los riesgos y las condiciones en las que se prestan los servicios de educación a nivel de preescolar en México. Asimismo, se debe fomentar la mejora continua de la calidad de la INFE para consolidar el derecho a la educación de todos los niños y las niñas de este país.
Poesia brasileira e ditadura: memória e desaparecimento em Ricardo Domeneck, Eduardo Sterzi, Paulo Ferraz e Priscila Figueiredo
Authors: Fernandes Pádua
Published: May 2021

O artigo analisa poemas de Ricardo Domeneck, Eduardo Sterzi, Paulo Ferraz e Priscila Figueiredo, que tratam de questões sobre graves violações de direitos humanos cometidas pelo Estado brasileiro, como a memória dos desaparecidos ou das vítimas da ditadura militar. A análise enquadra-se no campo da literatura e justiça de transição, com o objetivo de estudar o cruzamento entre invenção literária e memória social, no tocante ao legado dos crimes contra a humanidade praticados pelo Estado brasileiro. Todos esses autores nasceram nos anos 1970, durante a ditadura militar no Brasil, que durou de 1964 a 1985. Os poemas analisados foram escritos no século XXI, em um novo ciclo de memória cultural no Brasil, segundo a hipótese de Rebecca Atencio, no qual os temas ligados à ditadura voltaram a ser objeto da literatura brasileira com mais frequência. No caso de Paulo Ferraz, o poema diz respeito à Era Vargas (1930-1945). Domeneck, cujo poema é mencionado no relatório da Comissão Nacional da Verdade, e Sterzi referem-se à ditadura militar. Priscila Figueiredo trata das continuidades do passado autoritário nos crimes do Estado brasileiro após a democratização. Nesses quatro casos, a poética desses autores difere da que argentinos reunidos sob a categoria dos “hijos” têm estabelecido.
La lucha contra el olvido de las Madres de "Falsos Positivos" de Soacha y Bogotá (MAFAPO): condiciones y formas de movilizar una memoria subterránea (2008-2018)
Authors: Gutiérrez Rodríguez Carlos Arturo
Published: May 2021

La tensión (porosa, múltiple y siempre inacabada) entre la memoria y el olvido, está mediada por las acciones. humanas que destacan ciertos hechos del pasado reciente, con objetivos políticos de cara a nuevas coyunturas. En ese universo, entran en disputa diferentes memorias, que ponen en juego subjetividades, emociones, formas, intereses, narrativas, condiciones sociales y relaciones de poder. La tesis reseñada se ubica en un rincón específico de ese mundo de luchas memoriales. En ella se aborda la lucha de un colectivo de Madres colombianas: Las Madres de ‘Falsos Positivos’ (MAFAPO), cuyos hijos fueron asesinados en el marco de una política del Ejército Nacional de Colombia comúnmente conocida bajo el nombre de ‘falsos positivos’.
Uma análise axiológica dos projetos de lei sobre pessoas trans e esporte no Brasil
Authors: Garcia Rafael Marques , Pereira Erik Giuseppe Barbosa
Published: May 2021

O presente trabalho objetivou analisar os enunciados de seis Projetos de Lei protocolados em Assembleias Legislativas nacionais que visam regulamentar a participação de atletas trans no esporte brasileiro, mais especificamente quais as bases fundamentalistas utilizadas pelos deputados autores para se posicionarem axiologicamente acerca da temática. Metodologicamente, analisamos nosso material de acordo com a técnica de análise documental. Como resultados, pudemos constatar que todos os projetos se alicerçam em aspectos unicamente biológicos sobre os sexos, apresentam fragilidades teórico-conceituais sobre as identificações e expressões de gênero e sexualidades, propõem como solução esportiva alternativas excludentes e/ou vexatórias ao público de atletas trans que queiram competir no Brasil e não apresentam indicações bibliográficas para as afirmações conclusivas às quais sinalizam. Por fim, desejamos que a presente pesquisa se torne mais uma potente oportunidade de questionar as normas que permeiam a esfera legislativa do/no esporte brasileiro e, assim, revitalizá-lo à luz dos princípios básicos de nossa Constituição.
La formación de género en movimiento. Modelo-política de género en la UACJ y su desarrollo en la Licenciatura de Entrenamiento Deportivo en Ciudad Juárez
Authors: Lara Rodríguez Luis Manuel , Juárez Lozano Ricardo , Balderas Domínguez Jorge
Published: May 2021

El deporte permite una variedad de estrategias de uso social. Una de ellas, el conformarse como una herramienta pedagógica pertinente para constituir una perspectiva de género. Ciertamente, para ello se requiere una política institucional, que constituye acciones, procesos que pueden llegar a influir en una comunidad universitaria. En este trabajo el objetivo es analizar cómo es que se ha desarrollado la Política de género en la Universidad Autónoma de Ciudad Juárez, con una metodología con enfoque descriptivo desde la revisión de documentos fundantes y operativos de dicha política y aquellas estrategias alternas. Se discute cómo es que este proceso se ubica dentro del Programa de Licenciatura en Entrenamiento Deportivo, en donde se forma a los futuros/as profesores/as de educación física, dentro de un contexto regional, en México, abatido por inseguridad pública y los feminicidios. Se concluye sobre las áreas de oportunidad que la política de género que se desarrolla en la UACJ debe establecer, para constituir una cultura de género que impacte tanto a estudiantes como a docentes.
Género y carreras políticas en América Latina: la brecha en la permanencia legislativa
Authors:   Profesora titular de Ciencia Política e investigadora, Instituto de Iberoamérica, Universidad de Salamanca, García Montero Mercedes , Rivas Pérez Cristina
Published: May 2021

El artículo analiza la posibilidad que tienen las parlamentarias latinoamericanas de desarrollar una carrera legislativa que les permita afianzar su trayectoria al interior del Parlamento. A partir de los datos pertenecientes a 18 países de América Latina contenidos en la base de datos del Proyecto de Élites Parlamentarias Latinoamericanas (PELA-USAL), se ponen a prueba diferentes determinantes con potencial impacto en la permanencia legislativa: la ambición y la dedicación, la carrera política, el partido político, así como las características sociodemográficas de los y las parlamentarias. Además, para el caso de las diputadas, se contrasta el peso de factores que la literatura sobre género ha encontrado como relevantes. Los hallazgos revelan que la carrera legislativa difiere por razón de género, al ser diferentes los elementos que inciden en la probabilidad de continuar en el cargo de los legisladores y las legisladoras.

Published: May 2021

A noção de patrimônio histórico e cultural está ligada a bens, materiais ou imateriais, que abrangem a Nação ou que são circunscritos a certas regiões. Determinados locais possuem a aptidão para ganhar a proteção legal aplicável ao patrimônio histórico e cultural. Este artigo objetivou avaliar a possibilidade de caracterização da Gruta de Santa Emídia – Comunidade rural do Bom Sossego/ Irineópolis-SC, como patrimônio histórico e cultural frente à legislação atual que rege a matéria. Verificou-se que a gruta está ligada à tradição de São João Maria e possui vinculação a fatos ocorridos no Movimento Sertanejo do Contestado (Guerra do Contestado). Esses dados mostram-se prementes, especialmente pela expansão dos reflorestamentos de pinus elliottii no entorno da Gruta, que altera significativamente a paisagem e dificulta a peregrinação dos romeiros até o local. Assim, possui as características necessárias para ser tombada, desde que haja ação nesse sentido por parte do poder público.
