Authors: Miarka-Lachendro Joanna , Kowalska Małgorzata
Published: June 2018

Zawód kuratora sądowego zaliczany jest do niebezpiecznych. Kurator sądowy w ramach pełnionych obowiązków musi mieć stały kontakt z osobami dozorowanymi, skazanymi prawomocnymi wyrokami na kary o charakterze wolnościowym, wywodzącymi się najczęściej z patologicznych środowisk społecznych. Kontakt z nimi lub ich otoczeniem często wiąże się z agresją słowną lub czynną wobec kuratora.
Celem prezentowanej pracy jest przedstawienie obszarów ryzyka w pracy społecznych kuratorów sądowych ds. karnych na podstawie przeglądu dostępnej literatury przedmiotu. Autorki skoncentrowały się na aspektach pozwalających na zwiększenie lub poprawę bezpieczeństwa pracy kuratorów. Przegląd piśmiennictwa pozwolił na ich pogrupowanie oraz usystematyzowanie. Sprowadza się on do takich obszarów, jak zagrożenia związane z cechami osobowościowymi kuratora, jego statusem prawnym, ze środowiskiem podopiecznego, a także stanem zdrowia osoby dozorowanej.
La formación del profesor de educación física
Authors: Aranguiza Hugo
Published: June 2018

El currículum al ser concebido como una práctica desarrollada a través de múltiples procesos y en la que confluyen diversos subsistemas o prácticas diferentes, es condición que no admite duda que la acción del profesor es un elemento importante en la concreción de ese proceso. En el profesor recaen no sólo las determinaciones que debe considerar relativo al conocimiento o de los componentes diversos que se manifiestan en el currículum, sino que debe tomar en cuenta las obligaciones respecto de sus propios alumnos, del medio social concreto en el que están insertos, y que debe corresponder con una intervención responsable sobre ellos. Aunque la Educación Física debe considerar los requerimientos o demandas de la sociedad o sociedades concretas en las que se vive, derivados de filosofías socio-políticas determinadas, pero no en la fijación de grandes metas. Sin embargo, estas demandas de una determinada sociedad podrán estar presentes en objetivos más específicos. De esta forma, el hombre que vive en las distintas sociedades es ante todo un ser corporal, capaz de movimiento y necesitado de movimientos (ARANGUIZ, 1992, p37-61).
Elias: solidão e morte
Authors: Lucena Ricardo de
Published: June 2018

Este artigo discute e analisa a obra "La soledad de los moribundos" de autoria de Nobert Elias. O texto trata da morte e do envelhecimento e da forma como os indivíduos nas sociedades desenvolvidas do Ocidente lidavam com esses fatores no passado e como lidamos hoje. O tratamento dado ao tema por Elias torna o texto como uma síntese de muitos conceitos abordados por ele em vários outros trabalhos. Aqui discorri sobre dois aspectos: primeiro, o crescente grau de pacificação interna das sociedades hodiernas e, segundo, o alto grau de individualização. O intuito foi mostrar que Elias considera a morte e o modo de tratar os moribundos como um dos pontos débeis das sociedades desenvolvi¬das de nosso tempo.

Reflexões sobre os significados de recreação e de lazer no Brasil e emergência de estudos sobre o assunto (1926-1964)
Authors: Gomes Luciane Luce
Published: June 2018

discussão sobre as trajetórias percorridas pela recreação e pelo lazer no Brasil, focalizando os significados por ambos incorporados e a emergência de estudos sobre o assunto. A estratégia metodológica adotada foi à análise de três experiências institucionais, selecionadas a partir do papel de destaque assumido na literatura da época. Foram identificados significados distintos para a recreação, dependendo da trajetória percorrida em nossa sociedade, do público alvo atingido e das finalidades alcançadas. O lazer permaneceu, no entanto, sendo concebido como um tempo vago e ocioso, que deveria ser adequadamente preenchido. Desde as primeiras décadas do século XX, identifica-se uma preocupação com a problemática do lazer, mobilizando a organização de estratégias de intervenção e estudos sobre o assunto.

Métodos de avaliação de isótopos estáveis (δ2h E δ18o) na hidrologia: uma revisão
Authors: Barbosa Natanael da Silva , Barbosa Natali da Silva , Salles Lucas de Queiroz
Published: June 2018

Atualmente, através do ciclo hidrológico pode-se observar que toda a água da Terra é de alguma forma afetada por atividades antrópicas. Com a perspectiva de crescente escassez, as decisões de onde extrair, utilizar e administrar a água deve ser baseada em informações confiáveis, de forma a proteger este recurso para as gerações futuras. Nesse contexto, a utilização dos isótopos estáveis na hidrologia possibilita interpretações da origem e mecanismos de recarga das águas subterrâneas, separação de hidrogramas, drenança vertical entre aquíferos, riscos de salinização e contaminação dos recursos hídricos, dentre outros. A razão pelo qual os isótopos estáveis são úteis nos estudos hidrológicos se deve às reações físico-químicas entre as espécies químicas, que promovem um fracionamento dos isótopos do mesmo elemento entre reagentes e produtos. Os dados isotópicos de δ 18O e δ 2H refletem os valores das precipitações médias locais. Esses geralmente são modificados por processos de difusão que podem alterar os valores isotópicos antes que a água alcançe a zona saturada. Sua importância em relação aos estudos hidrológicos tradicionais é que os isótopos estáveis fazem parte da própria molécula de água, tornando as interpretações mais precisas e independentes do grau de variabilidade e frequência de amostragem. Sob essa perspectiva, nos dias atuais, a integração do maior número possível de marcadores químicos e isotópicos constitui uma importante fronteira de pesquisa hidrológica e na gestão integrada dos recursos hídricos.

Authors: Jing Mu , Changyuan Wang
Published: June 2018

Levenberg-Marquardt (abbr.L-M) method based iterative square root cubature Kalman filter (abbr. ISRCKFLM) inherits the numerical stability of square root Cubature Kalman filter and effectively suppresses the influence of the larger initial estimation error and the nonlinearity of the measurement equation on the state estimation in the nonlinear state estimation due to obtaining the optimal state and variance estimates using the latest measurement through L-M method. We apply the ISRCKFLM algorithm to the state estimation of maneuvering re-entry target tracking, the simulation results demonstrate that the ISRCKFLM algorithm has better accuracy of state estimation, comparable to Unscented Kalman filter and square root Cubature Kalman filter, according to estimation error analysis of the position, velocity, drag coefficient, turn coefficient and climbing force coefficient, and has fast convergence rate.

Research of Email Classification based on Deep Neural Network
Authors: Yawen Wang , Fan Yu , Yanxi Wei
Published: June 2018

The effective distinction between normal email and spam, so as to maximize the possible of filtering spam has become a research hotspot currently. Naive bayes algorithm is a kind of frequently-used email classification and it is a statistical-based classification algorithm. It assumes that the attributes are independent of each other when given the target value. This hypothesis is apparently impossible in the email classification, so the accuracy of email classification based on naive bayes algorithm is low. In allusion to the problem of poor accuracy of email classification based on naive bayes algorithm, scholars have proposed some new email classification algorithms. The email classification algorithm based on deep neural network is one kind of them. The deep neural network is an artificial neural network with full connection between layer and layer. The algorithm extracted the email feature from the training email samples and constructed a DNN with multiple hidden layers, the DNN classifier was generated by training samples, and finally the testing emails were classified, and they were marked whether they were spam or not. In order to verify the effect of the email classification algorithm based on DNN, in this paper we constructed a DNN with 2 hidden layers. The number of nodes in each hidden layer was 30. When the training set was trained, we set up 2000 batches, and each batch has 3 trained data. We used the famous Spam Base dataset as the data set. The experiment result showed that DNN was higher than naive Bayes in the accuracy of email classification when the proportion of the training set was 10%, 20%, 30%, 40% and 50% respectively, and DNN showed a good classification effect. With the development of science and technology, spam manifests in many forms and the damage of it is more serious, this puts forward higher requirements for the accuracy of spam recognition. The focus of next research will be combining various algorithms to further improve the effect of email classification.

Published: June 2018

Digital holography has a wide range of applications in displaying the surface morphology of three-dimensional objects. There have been many studies on the physical methods and implementation methods of digital holography. One of the main problems at present is to design a stable and fast reconfiguration software. This paper analyzes the basic principle of convolution based off-axis digital holographic reconstruction, and presents the process of 3D reconstruction of off-axis digital holography. The 3D reconstruction software of digital holography is designed and developed according to the basic principle and the process of reconstruction, and the parallel operation of 3D reconstruction is realized by OpenMP. Results show that the software can help researchers conveniently realize digital holographic three-dimensional reconstruction. The reconstructed parameters can be adjusted according to the requirements, and the spectra, intensity maps, phase maps and other information required in the reconstruction process can be obtained. The software meets the needs of digital three-dimensional reconstruction.

Isolation of Bacteriocin-producing Staphylococcus spp. Strains from Human Skin Wounds, Soft Tissue Infections and Bovine Mastitis
Authors: ZALEWSKA MAGDALENA , CHUREY JOHN J. , WOROBO RANDY W. , MILEWSKI SŁAWOMIR , SZWEDA PIOTR
Published: June 2018

A collection of 206 Staphylococcus spp. isolates was investigated for their ability to produce compounds exhibiting antistaphylococcal activity. This group included Staphylococcus aureus, Staphylococcus epidermidis, Staphylococcus xylosus strains recovered from bovine mastitis (n = 158) and human skin wounds and soft tissues infections (n = 48). Production of substances with antimicrobial activity was observed in six strains. Five of them were recovered from bovine mastitis, and one was isolated from the infected human skin wound. Three of the six antimicrobials produced by the different strains showed substantial loss of antimicrobial activity upon treatment with proteolytic enzymes, which suggests their peptidic structure. Additional studies have shown that one of the putative bacteriocins was efficiently secreted to the liquid medium, facilitating its large-scale production and isolation. The peptide produced by the M2B strain exhibited promising activity; however, against narrow spectrum of Staphylococcus spp. clinical and animal isolates. Growth inhibition was observed only in the case of 13 (including nine S. aureus, three S. xylosus and one S. epidermidis strains) out of 206 strains tested. Important advantage of the produced agent was its high thermal stability. Fifteen minutes of incubation at 90°C did not affect its antimicrobial potential. The highest efficiency of production of the agent was demonstrated in TSB medium after 24 hours at 37°C. The researches revealed that ability to production of bacteriocin among staphylococci is not very common. Only one (S. xylosus strain assigned as M2B) out of 206 strains tested produced satisfactory amounts of antistaphylococcal bacteriocin. In spite of that, we would encourage other researchers for investigation of their collections of Staphylococcus spp. isolates towards selection strains producing antimicrobial agents.

Mastitis in goats is mainly caused by coagulase-negative Staphylococcus (CNS). The identification methods for this group are based on evaluating the expression of phenotypic characteristics such as the ability to metabolize various substrates; however, this is disadvantageous as these methods are dependent on gene expression. In recent years, genotyping methods such as the Multiple Locus Variable-Number Tandem Repeat Analysis (MLVA) and gene identification have been useful for epidemiological study of several bacterial species. To develop a genotyping method, the genome sequence of Staphylococcus chromogenes MU970 was analysed. The analysis showed nine virulence genes described in Staphylococcus aureus. The MLVA was developed using four loci identified in the genome of S. chromogenes MU970. This genotyping method was examined in 23 strains of CNS isolated from goat mastitis. The rate of discrimination for MLVA was 0.8893, and the highest rates of discrimination per the index of Simpson and Hunter-Gaston were 0.926 and 0.968 for the locus 346_06, respectively. The virulence genes were present in all strains of S. chromogenes but not in other CNS. The genotyping method presented in this paper is a viable and easy method for typifying CNS isolates from mastitis cases in different regions and is an ideal mean of tracking this disease.
Development of a Shortened Version of the Adolescent Stress Questionnaire (ASQ-S): construct validity and sex invariance in a large sample of Swedish adolescents
Authors: Anniko Malin K. , Boersma Katja , van Wijk Nikil Ph. L. , Byrne Don , Tillfors Maria
Published: June 2018

Background: Stressor experience is an important topic of research concerning adolescent health and ill-health. For this, valid and reliable measures of adolescent stress are needed. The Adolescent Stress Questionnaire 2 was developed to tap into stressor domains specific for adolescence. Psychometric evaluations in Australian and European samples have indicated adequate psychometric properties. However, the ASQ-2 is quite extensive, which may render its use in large cohort studies, where several aspects of adolescent health are investigated, inconvenient and problematic.

Objective: To evaluate the psychometric properties of a short version of the ASQ-2 (ASQ-S) in terms of construct validity and factorial invariance across gender.

Method: The ASQ-2 was translated into Swedish and items were retained from nine of the ten scales based on factor loadings. One scale (stress of emerging adult responsibilities) was removed entirely due to low internal consistency and variance explained. The remaining 27 items were piloted and then included in an ongoing 5-year longitudinal study involving the participation of all students in the 7th and 8th grade in public schools from three Swedish municipalities (N = 2768, 47.5 % girls, mean age 13.64 years). For this study data from the first and second wave was used.

Results: A nine factor Confirmatory Factor Analysis (CFA) showed a good fit to the data and invariance across sexes was supported. The nine scales correlated positively with depressive symptoms, anxiety and worry and negatively with self-esteem. Girls reported higher stress levels than boys in eight of the nine scales. Stressors related to peer pressure predicted reported levels of anxiety and worry one year later, whereas stressors related to romantic relationships predicted depressive symptoms.

Conclusions: Overall this study suggests that the ASQ-S could be a valid measure of adolescent stressor experience and psychometrically equivalent to the full ASQ-2.
SEARCHING FOR CAUSES OF NECROTISING ENTEROCOLITIS. AN APPLICATION OF PROPENSITY MATCHING
Authors: Longford Nicholas T.
Published: June 2018

Necrotising enterocolitis (NEC) is a disease of the gastrointestinal tract afflicting preterm-born infants in the first few weeks of their lives. We estimate the effect of changing the feeding regimen of infants in their first 14 postnatal days by analysing the data from the UK National Neonatal Research Database. We avoid some problems with drawing causal inferences from observational data by reducing the analysis to the infants who spent the first 14 postnatal days (or longer) in neonatal care and for whom NEC was not suspected in this period. This reduction enables us to use summaries of the feeding regimen in this period as background variables in a potential outcomes framework. Large size of the cohort is a distinct advantage of our study. Its results inform the design of a randomised clinical trial for preventing NEC, and the choice of its active treatment(s) in particular.
The simple-cubic structure of elemental Polonium and its relation to combined charge and orbital order in other elemental chalcogens
Authors: Silva Ana , van Wezel Jasper
Published: June 2018

Polonium is the only element to crystallise into a simple cubic
structure under ambiant conditions. Moreover, at high temperatures it
undergoes a structural phase transition into a less
symmetric trigonal configuration. It has long been suspected that the
strong spin-orbit coupling in Polonium is involved in both
peculiarities, but the precise mechanism by which it operates remains
controversial. Here, we introduce a single microscopic model capable of
capturing the atomic structure of all chalcogen crystals: Selenium,
Tellurium, and Polonium. We show that the strong spin-orbit coupling in
Polonium suppresses the trigonal charge and orbital ordered state known
to be the ground state configuration of Selenium and Tellurium, and
allows the simple cubic state to prevail instead. We also confirm a
recent suggestion based on ab initio calculations that
a small increase in the lattice constant may effectively decrease the
role of spin-orbit coupling, leading to a re-emergence of the trigonal
orbital ordered state at high temperatures. We conclude that Polonium is a unique element, in which spins, orbitals, electronic charges, and lattice deformations all cooperate and collectively cause the emergence of the only elemental crystal structure with the simplest possible, cubic, lattice.
La representación de la muerte en el videojuego
Authors: Maté Diego
Published: June 2018

Desde sus inicios, el videojuego desplegó un espectro estético que posibilitó nuevas formas de representar la muerte. Podría pensarse que las diferencias entre el videojuego y otros medios como el cine surgen del encuentro de dos grandes formas culturales como el relato y el juego, pero el panorama actual muestra un escenario pleno de mixturas y pasajes. En este trabajo se señalan los rasgos característicos que adoptó la representación de la muerte en el videojuego como la recurrencia, su inserción en un régimen lúdico, su distanciamiento de las semantizaciones más frecuentes propias de géneros narrativos y su tendencia a la disrupción del relato. Además, se describen dos grandes estrategias representativas que el medio elaboró en distintos momentos de su historia, y que en la actualidad conviven y dominan en buena medida el paisaje estético videolúdico: en una se sugiere el acto de morir invisibilizándolo, en otra se apuesta a la espectacularización de la muerte a través de una maximización audiovisual. Estas dos formas no se presentan en estado de pureza ni excluyen otras vías representativas posibles, pero permiten observar tendencias que gozaron (y gozan) de una gran estabilidad. Por último, se analizan cuatro casos que producen un desvío respecto de la implementación del acto de morir como penalización y retroceso de carácter lúdico, y proponen soluciones alternativas a la cuestión en torno de la representación de la muerte.
¿Otakus y gamers en Buenos Aires?: dinámica compleja y estereotipos negativos
Authors: Ricciardelli-Dusseldorp Santiago José
Published: June 2018

En este artículo me propongo problematizar la identidad otaku basado en su auto-adscripción, alejándome de las posturas que separan a otakus y gamers como dos grupos identitarios diferentes dentro de un espacio común, con luchas discursivas y espaciales entre ellos. El objetivo principal de este trabajo es refinar la categoría de otaku y explorar la dinámica de su identidad como grupo, entendiendo que la superficialidad de su definición acaba por esconder un panorama mucho más complejo en torno a su identidad. Los estereotipos negativos que suelen recaer en el colectivo otaku, y que son reafirmados por los medios masivos de comunicación, producen una serie de diferentes reacciones y estrategias, a veces conscientes y a veces no, de parte de los individuos para poder lidiar con dichos estereotipos. Entre tales reacciones se encuentra la autodenominación de gamer. A partir de un extenso trabajo de campo, entrevistas, etnografía virtual y una encuesta realizada entre dos de los principales grupos de Facebook especializados en la temática en Argentina, propongo resaltar que no hay indicadores que demuestren (o apoyen con fuerza) una separación entre los fanáticos y seguidores del anime, y aquellos fanáticos de los juegos de video. Por el contrario, entiendo que la auto-adscripción a la categoría gamer, en estos grupos y eventos, es más bien una de las tantas estrategias que se adoptan para lidiar con la estereotipación negativa hacia los otakus, antes que tratarse de una separación identitaria.

Authors: Karpenko A. A. , Kostyuchenko G. I. , Arzamastsev D. D.
Published: June 2018

The baseline levels of proinflammatory mediators (high-sensitivity C-reactive protein, Interleukin-6) and markers of endothelial damage (endothelin-1, von Willebrand factor ) in the blood serum were measured in 128 patients with atherosclerosis of the lower extremities who had underwent balloon angioplasty. Hemodynamically significant restenosis in patients with lesions of the iliac arteries was observed in 34% of patients, with the postoperative loss of the lumen being equal to 58.34.29%, while in the group of patients with stenosis of the femoral and popliteal arteries it accounted for 46%, with the postoperative loss of the lumen reaching 65.25.14%. A direct correlation between the level of indicators of proinflammatory mediators, markers of endothelial damage and the degree of ischemia of the lower extremities was identified. Also determined were the predictors of restenosis formation after angioplasty of the lower extremity arteries. The level of CRP tended to exceed 10.1 mg/l, IL-6 was over 6.1 pg/ml and ET-1 was higher than 0.8 ng/ml.
Influence of mechanical resistance of red cells on expressiveness of hemolysis after cardiopulmonary bypass

Published: June 2018

The study enrolled patients with ischemic heart disease with moderate (37 patients) and apparent hemolysis (18 patients) after coronary bypass surgery under cardiopulmonary bypass. Before and after the operation the concentration of free hemoglobin in blood plasma, mechanical resistance of red cells, content of TBA-active products and the general antioxidant activity in red cells were studied, while taking into account the artificial blood circulation activity and perfusion speed as well. It was established that among patients with apparent post-perfusion hemolysis the level of TBA-active products in red cells increased after surgery, while their general antioxidant activity tended to decrease. Development of moderate hemolysis is not accompanied by changes in the oxidant-antioxidant balance of red cells. There were no reliable differences in the duration of cardiopulmonary bypass, perfusion volume velocity, as well as mechanical resistance of red cells among the groups of patients at both levels of the study. Thus, individual-conditioned apparent post-perfusion hemolysis is based on a free-radical mechanism of red cell damage, and not on a mechanical trauma of blood cells when under cardiopulmonary bypass.

It is shown that administration of G-CSF (Granulocyte Colony Stimulating Factor) to patients with chronic heart failure has a gematologic effect, while increasing the number of leukocytes and neutrophils in the peripheral blood. G-CSF leads to mobilization of progenitor cells (PCs) from the bone marrow into the peripheral blood. The basal content of CD34+ cells, the number of heart attacks and the time period from the last myocardial infarction effect the number of CD34+ cells after mobilization.

Qualitative data were analysed to identify emergent themes that described the caregiver experience.

(3) Results: The average age of nine caregivers was 64.86 years old and most caregivers were female (66%). Caregivers who attended the MY-OT intervention demonstrated less caregiver burden (47% decrease) and more positive aspects of caregiving (26% increase) than those who did not attend. Four qualitative themes emerged and included: positive changes in daily life; being in the present; new learning opportunities for the dyad and individual; and building a sense of community.

(4) Conclusions: Yoga and occupational therapy appeared helpful to caregivers through reducing caregiver burden, increasing positive aspects of caregiving, and contributing to positive experiences over all. Future research studies should be developed to include the caregiver and address the caregiver dyad

In recent years, computed tomography (CT) has become very common in veterinary medicine. It is well known that testicles are organs with high radiosensitivity and their function can be impaired even after exposure to low radiation doses. In this work, we calculated the absorbed radiation doses after CT was performed with different voltage/current levels and correlated it with the activity of antioxidant enzymes in rabbit testicles. Two hours after CT, the activities of catalase (CAT) and glutathione peroxidase (GSH-Px) were increased in the testicles of animals that received an absorbed dose of 29.2 mGy. The same changes, along with elevated glutathione reductase (GR) activity, were observed after 7 days in animals that received the highest absorbed dose (46.3 mGy). It would appear that absorbed doses above 27.8 mGy provoked the antioxidant reaction but the time scale of the reaction was dose-dependent. Examination of the obtained results revealed that the main denominator of CT influence was a higher current. Our results suggest that CT influences the antioxidant status in rabbit testicles. The changes in antioxidant enzyme activities were dose- and time-dependent and influenced by the applied current.

Background/Aim. Despite the availability of safe and effective vaccine since 1982, hepatitis B virus (HBV) infection still remains a major occupational disease among health care workers (HCWs) worldwide. The aim of this study was to estimate the level of knowledge regarding HBV among HCWs in Serbia. Methods. A random sample of 352 HCWs, stratified by occupation, was selected from the list of employees in the Clinical Centre of Serbia during December 2015. Anonymous questionnaire was used in data collection. Data were statistically assessed. Results. The mean HBV knowledge score was 22.9 ? 4.8 (out of maximum 30). Better knowledge score correlated with higher education attainment (? = 0.377; p < 0.001), younger age (? = -0.113; p = 0.034) and less working experience (?=-0.127; p = 0.017). We observed that those HCWs who were previously vaccinated against hepatitis B demonstrated statistically significantly higher knowledge level (t = 5.656, p < 0.001) compared to HCWs who were not vaccinated (23.9 ? 3.7 vs. 20.9 ? 5.8, respectively). Conclusion. We found poor level of knowledge on some aspects of HBV infection among HCWs in Serbia. Tailoring of education campaigns in this high-risk exposure group is necessary. Education intervention should focus on change of attitudes and behaviour modification to ensure safe and responsible health care environment.

OBJECTIVE

To assess the effect of empagliflozin on bone fractures and bone mineral density in patients with type 2 diabetes in pooled placebo-controlled trial data and a head-to-head study versus glimepiride.

RESEARCH DESIGN AND METHODS

Pooled data were analyzed from patients who were randomized 1:1:1 to empagliflozin 10 mg, empagliflozin 25 mg, or placebo in phase I–III clinical trials. Data were also analyzed from the EMPA-REG H2H-SU trial in which patients received empagliflozin 25 mg or glimepiride as an add-on to metformin for 104 weeks with a 104-week extension. Bone fracture adverse events (AEs) were evaluated through a search of investigator-reported (nonadjudicated) events.

RESULTS

In the pooled analysis, bone fracture AEs were reported in 119 of 4,221 (2.8%), 105 of 4,196 (2.5%), and 123 of 4,203 (2.9%) patients in the empagliflozin 10 mg, empagliflozin 25 mg, and placebo groups, respectively (rates of 1.55, 1.36, and 1.69/100 patient-years, respectively). In the EMPA-REG H2H-SU trial, bone fracture AEs were reported in 31 of 765 (4.1%) patients receiving empagliflozin 25 mg and in 33 of 780 (4.2%) patients receiving glimepiride (rates of 1.28 and 1.40/100 patient-years, respectively).

CONCLUSIONS

Empagliflozin did not increase the risk of bone fracture compared with placebo in a pooled analysis of >12,000 patients or compared with glimepiride in a 4-year head-to-head study.

El impulsor cualitativo en problemas de cáculo diferencial
Authors: Córdova Nelson Claudio
Published: June 2018

Este documento presenta un recurso heurístico denominado Impulsor cualitativo que ayuda efectivamente en la resolución de problemas. Este elemento es introducido especialmente en la etapa de análisis del proceso de resolución de un problema. Este proceso requiere de una fuerte dosis de creatividad y desarrollo de operaciones cognitivas, lo que permite a un estudiante explorar su mente en búsqueda de soluciones y le permite organizar su pensamiento con el propósito de alcanzar un objetivo ulterior, que es encontrar la solución al problema. (Córdova, Sanchez y Urrutia, 2016)En este artículo mostramos la utilización de este concepto para resolver problemas que se enseñan en el Cálculo Diferencial y que el común de los estudiantes tiene dificultades al tratar de resolver. Con esto se pretende mostrar una nueva alternativa para enfrentar y resolver problemas. Con la inserción de este nuevo concepto, esperamos contribuir al proceso enseñanza y aprendizaje del Cálculo Diferencial, y de la Matemática en general, de tal manera que al aplicar el Impulsor cualitativo como una herramienta, esta sea útil para el desarrollo integral del estudiante, y además como apoyo complementario a los docentes dentro en el proceso de enseñanza y aprendizaje de las matemáticas.
Higher education in the context of multiple modernity
Authors:   Ural Federal University, Antonova Natalia Leonidovna
Published: June 2018

The study examines the problems of the Russian system of higher education in the context of multiple modernity. Changes in higher education are related to entering the global educational market. There has been an increase in the number of international students in the total student population. Universities need to create a favourable environment for their successful learning and adaptation that are to increase their competitiveness on the educational services market. The research identifies the main problem areas of Russian universities that prevent the entry of international students into the learning environment. Curricula and syllabi are not adapted to students’ requests. The competency-based model of the graduate does not take into account the needs of the national economies of students’ home countries. The problems of modern learning technologies applied by teachers and their readiness for intercultural dialogue are not resolved. Despite the language barrier, international students learn and reproduce educational, leisure, and dietary practices of Russian students while maintaining the traditions and customs of their ethnonational group.
Das provocações cearenses ao pós-secular: reflexões sobre Igreja e Sociedade no Nordeste brasileiro
Authors: Barbosa José Luciano Albino
Published: June 2018

Uma das tarefas próprias da investigação sociológica diz respeito à capacidade de esclarecer o processo histórico a partir do qual, certas convicções se naturalizam. Significa desvendar, por criteriosas fontes e análises sistemáticas, a tecitura da realidade social, naquilo que  ela tem de conflitos, arranjos e interesses diversos. Em outras palavras, o trabalho sociológico consiste em “abrir as cortinas” que escondem e mistificam as articulações construídas pelas pessoas, clareando o que se mostra dado, imediato e (pre)concebido da ordem social. Tomar a realidade por objeto científico se refere à tentativa de compreendê-la segundo essas orientações “escondidas”.
Does the Exchange-Correlation Kernel ƒxc Have a Very Long-Ranged Dependence on the Groundstate Electron Density?
Authors: Dobson John F. , Angyan Janos G. , Gould Tim
Published: June 2018

We consider the dispersion energy between two well-separated molecules. Provided that exchange overlap effects can be neglected, the Generalized Casimir Polder (GCP) formula gives the dispersion energy exactly to second order in the inter-system Coulomb pair potential, in terms of the density response functions of the isolated molecules. One can alternatively calculate the dispersion interaction from the density response in a supramolecular (dimer) energy TDDFT/ACFD calculation. This uses the density response from Time Dependent Density Functional Theory (TDDFT) and the Adiabatic Connection (ACFD) groundtstate electronic energy formula, and treats the two systems together. Some of us recently [JCTC 13, 5829 (2017)] showed that the supramolecular TDDFT/ACFD approach can fail to reproduce the exact GCP result, when the exchange-correlation kernel ƒxc in the TDDFT calculation is assumed to be local. Here we examine ways in which a nonlocal density dependence of ƒxc might be able to remove this discrepancy.
