Ao avaliar as variáveis sociodemográficas, observou-se que professores vinculados à rede estadual de ensino e do sexo feminino demonstraram maior indice de preocupação com a dimensão tarefa, enquanto os docentes que atuavam em apenas uma escola demonstraram maior preocupação com a dimensão consigo. Conclui-se que as preocupações apresentam comportamento semelhante com o avanço da carreira e que variáveis sociodemográficas tem baixo impacto de influencia no nível de preocupação docente.
Failure to detect equid herpesvirus types 1 and 4 DNA in placentae and healthy new-born Thoroughbred foals
Authors: Brown Lara J. , Brown Geoff , Kydd Julia , Stout Tom A.E. , Schulman Martin L.
Published: May 2019

Equid herpesvirus type 1 is primarily a respiratory tract virus associated with poor athletic performance that can also cause late gestation abortion, neonatal foal death and encephalomyelopathy. Horizontal transmission is well described, whereas evidence of vertical transmission of equid herpesvirus type 1 associated with the birth of a healthy foal has not been demonstrated. This study sampled a population of Thoroughbred mares (n = 71), and their healthy neonatal foals and foetal membranes, to test for the presence of both equid herpesvirus types 1 and 4 using a quantitative polymerase chain reaction assay. Foetal membrane swabs and tissue samples were taken immediately post-partum, and venous blood samples and nasal swabs were obtained from both mare and foal 8 h after birth. Neither equid herpesvirus type 1 nor equid herpesvirus type 4 nucleic acid was detected in any sample, and it was concluded that there was no active shedding of equid herpesvirus types 1 and 4 at the time of sampling. Consequently, no evidence of vertical transmission of these viruses could be found on this stud farm during the sampling period.

Authors: Kravtsov Dmitry Alexandrovich , Krokhmal Nikolai Evgen'evich , Shabanov Dmitry Aleksandrovich
Published: May 2019

Работа посвящена изучению пороговой вероятности наличия полноцветной раскраски в $r$ цветов у случайного $k$-однородного гиперграфа в биномиальной модели $H(n,k,p)$, т.е. такой раскраски, что каждое ребро гиперграфа содержит вершины всех $r$ цветов. Показано, что данная пороговая вероятность при фиксированных $r<k$ и растущем $n$ отвечает разреженному случаю, т.е. случаю $p=cn/{n\choose k}$ для положительного фиксированного $c$. Найдены ее очень близкие оценки в виде ограничений $c_1(r,k)<c_2(r,k)$ значений параметра $c$, где разность $c_2(r,k)-c_1(r,k)$ экспоненциально быстро стремится к нулю при заданном $r$ и растущем $k$.

Published: May 2019

Abstract. In open pit mining it is essential for processing and production scheduling to receive fast and accurate information about the fragmentation of a muck pile after a blast. In this work, we propose a novel machine-learning method that characterizes the muck pile directly from UAV images. In contrast to state-of-the-art approaches, that require heavy user interaction, expert knowledge and careful threshold settings, our method works fully automatically. We compute segmentation masks, bounding boxes and confidence values for each individual fragment in the muck pile on multiple scales to generate a globally consistent segmentation. Additionally, we recorded lab and real-world images to generate our own dataset for training the network. Our method shows very promising quantitative and qualitative results in all our experiments. Further, the results clearly indicate that our method generalizes to previously unseen data.
ENHANCED UAV NAVIGATION USING HALL-MAGNETIC AND AIR-MASS FLOW SENSORS IN INDOOR ENVIRONMENT

Published: May 2019

Abstract. The use of Unmanned Aerial Vehicles (UAVs) in many commercial and emergency applications has the potential to dramatically alter several industries, and, in the process, change our attitudes regarding their impact on our daily lives activities. The navigation system of these UAVs mainly depends on the integration between the Global Navigation Satellite Systems (GNSS) and Inertial Navigation System (INS) to estimate the positions, velocities, and attitudes (PVT) of the UAVs. However, GNSS signals are not always available everywhere and therefore during GNSS signal outages, the navigation system performance will deteriorate rapidly especially when using low-cost INS. Additional aiding sensors are required, during GNSS signal outages, to bound the INS errors and enhance the navigation system performance. This paper proposes the utilization of two sensors (Hall-magnetic and Air-Mass flow sensors) to act as flying odometer by estimating the UAV forward velocity. The estimated velocity is then integrated with INS through Extended Kalman Filter (EKF) to enhance the navigation solution estimation. A real experiment was carried out with the 3DR quadcopter while the proposed system is attached on the top of the quadcopter. The results showed great enhancement in the navigation system performance with more than 98% improvement when compared to the free running INS solution (dead-reckoning).
SLOPE FAILURE RISK ASSESSMENT MODELING USING TOPOGRAPHIC DATA AND NUMERICAL CALCULATION OF SOIL CONSERVATION BY TREE ROOT SYSTEMS

Published: May 2019

Abstract. In Japan, the frequency of sudden heavy rain events has recently increased, causing slope failures that in turn increase rates of damage to transit infrastructure such as railways and roads. To reduce this damage, there is a need to identify locations near railroad tracks that are at risk of slope failure. Thus, an assessment that predicts whether or not damage will occur due to external forces such as heavy rains is required, rather than a simple relative risk assessment based on identifying locations similar to those damaged in previous events. In this study, we developed a method for time series stability assessment of slopes during heavy rains using digital topographic data. This method uses topographic data to estimate topsoil thickness, which contributes to stability, and soil strength, which is affected by the root systems of vegetation on slopes. Using differences in these parameters between tree species and forest type, we were able to calculate slope stability and simulate slope failure during rainfall. The simulations allowed us to evaluate locations along routes where previous failures occurred, and to identify at-risk locations that have not yet experienced slope failure. This approach will improve forest management based on risk assessments for intensifying heavy rains.
AUTOMATIC EXTRACTION OF A NAVIGATION GRAPH INTENDED FOR INDOORGML FROM AN INDOOR POINT CLOUD
Authors: Flikweert P. , Peters R. , Díaz-Vilariño L. , Voûte R. , Staats B.
Published: May 2019

Abstract. Indoor environments tend to be more complex and more populated when buildings are accessible to the public. The need for knowing where people are, how they can get somewhere or how to reach them in these buildings is thus equally increasing. In this research point clouds are used, obtained by dynamic laser scanning of a building, since we cannot rely on architectural drawings for maps and paths, which can be outdated. The presented method focuses on the creation of an indoor navigation graph, based on IndoorGML structure, in a fast and automated way, while retaining the type of walkable surface. In this paper the focus has been on door detection, because doors are essential elements in an indoor environment, seeing that they connect spaces and are a logical step in a route. This paper describes a way to detect doors using 3D Medial Axis Transform (MAT) combined with the intelligence stored in the path of a mobile laser scanner, showing good first results. Additionally different spaces (e.g. rooms and corridors) in the building are identified and slopes and stairs in walkable spaces are detected. This results in a navigation graph which can be stored in an IndoorGML structure.
Re-forming Manon: A New History of Edith Wharton's 1901 Play, Manon Lescaut
Authors: Chinery Mary
Published: May 2019

Edith Wharton's unpublished Manon Lescaut, A Play in Five Acts, has been overlooked as a significant work in Wharton's early career. Reduced to the term “adaptation,” which diminishes its importance, Wharton, in fact, revised Abbé Prévost's treatment of the fallen woman stereotype as she explored literary and dramatic form. New materials from the Paul Kester Papers at the New York Public Library, period newspaper articles, letters from Walter Berry to Wharton, and a second copy of the manuscript itself offer a new history of this drama. Composed in 1900, the play almost made it to the New York stage starring Julia Marlowe after the actress Marie Tempest withdrew. But a fall 1900 dispute with Marlowe's manager, C. B. Dillingham, regarding Manon's moral character and the length of the play resulted in Wharton's defense of her creative choices in three letters and five pages of Notes. Additionally, letters by Walter Berry to Wharton discuss the possibility of replacing Marlowe with Olga Nethersole, the actress who was indicted on indecency charges for her performance in Clyde Fitch's Sapho. The context of Wharton's Manon Lescaut shows a playwright in charge of her craft, navigating the complicated theatrical world, and defending her creative vision.
Can a Shavian Love My Fair Lady?
Authors: Reynolds Jean
Published: May 2019

Many Shavians were dismayed when My Fair Lady came to Broadway in 1956. One problem was that Shaw had always refused to authorize a musical version of Pygmalion. There were also fears that Pygmalion would lose some of its Shavian qualities in the Lerner and Loewe adaptation. But more than sixty years have passed since the Broadway opening, and My Fair Lady has proven to be a Shavian success in more ways than one.
Incorporación de los odontólogos en los procesos de transformación al modelo de salud familiar de la atencion primaria en Chile
Authors: Farfán Jaime , Valenzuela María Teresa
Published: May 2019

Objetivo: Describir la incorporación de los odontólogos en la implementación del modelo de salud familiar de la atención primaria. Metodología: Se realizó estudio descriptivo de corte transversal, mediante encuesta enviada vía e-mail a 183 jefes de programas odontológicos de CESFAM acreditados del país. Resultados: El 94% de los equipos tiene a lo menos un odontólogo capacitado en relación al modelo; de ellos solo un 37% lo ha hecho mediante un diplomado de Salud Familiar, el resto ha realizado cursos o jornadas de capacitación en su establecimiento. Con respecto a la participación en actividades que ofrece el modelo, se observa una autopercepción positiva, la que disminuye con respecto a la incorporación de otros profesionales de la salud en los programas odontológicos o en la realización de nuevas prestaciones (14% realiza consejerías familiares, 33% no realiza atención sectorizada). El 83% de los equipos realiza actividades de promoción y prevención en establecimientos educacionales; sin embargo se desaprovechan instancias que permitirían ejecutar el programa en forma integral (46% participa del programa “Chile Crece Contigo” y solo 15% en comités “Vida Sana”). Discusión: Se observa un alto porcentaje de capacitación de los equipos encuestados, que difieren en el tipo de formación y carga académica. Además, la alta participación en las actividades que ofrece el modelo no se ve reflejada en la integración de temas de salud bucal en ellas. Por último, se genera la necesidad de que a nivel central se formulen protocolos que permitan a los equipos odontológicos programar y ejecutar nuevas estrategias cuantificando su rendimiento.

Published: May 2019

Objetivos: En este trabajo se determinaron los niveles de residualidad de plaguicidas organoclorados y organofosforados en muestras de sangre periférica de trabajadores agrícolas –fumigadores– en el municipio de Barcelona, Quindío, Colombia. Método: Los trabajadores fueron escogidos al azar dentro de los principales cultivos abastecedores de frutas y verduras de la región. Para la extracción y determinación de los analitos en sangre, se usó la técnica de micro-extracción en fase sólida en modo head space y cromatografía de gases capilar dotado con un detector de micro captura de electrones. Resultados: Como resultado se encontraron residuos de 21 plaguicidas de tipo organoclorados y organofosforados; la mayoría de estos en alta concentración (>0.01 ppm) y prohibidos por la legislación nacional e internacional, sugiriendo que aún siguen siendo utilizados ilegalmente. De la residualidad encontrada, los plaguicidas más representativos fueron: beta-BHC y endosulfan, hallados en el 50% de las personas evaluadas. Asimismo, se descubrió que entre el 20 y 40% de las personas tenían residuos de endrin aldehído, forato, sulfotep, disulfoton y thionazin, en circunstancia que la mayoría de estos son de categoría toxicología I y II, comprobando el alto riesgo al que se exponen constantemente los individuos que aplican estos compuestos y la falta de atención e información por parte de las entidades responsables de autorización y fiscalización de su uso. Conclusiones: En este sentido, los resultados encontrados en este trabajo demuestran la importancia de continuar con los estudios de monitoreo y control de calidad de los principales alimentos, fuentes hídricas y trabajadores agrícolas, para así informar a la población acerca de los riesgos a los que está expuesta.

A Framework for Infusing Critical Thinking into Chinese College EFL Learners’ Argumentative Writing Process
Authors: Lu Chunxia
Published: May 2019

Written argumentation, as a language skill and a cognitive skill as well, is not easy for EFL learners. In China, related studies found that college EFL learners are weak in written argumentation due to the deficiency of critical thinking. In order to enhance Chinese college EFL learners’ argumentative writing ability, this paper reviewed the nature of argumentative writing, the relationship between critical thinking and argumentative writing and previous studies on effects of critical thinking instruction into argumentative writing, and then pointed out that it is reasonable to infuse critical thinking into argumentative writing process in Chinese EFL context. With teachers’ feedback and students’ reflection as the pedagogical tool, the author synthesized an instruction framework for infusing critical thinking skills into Chinese EFL learners’ argumentative writing process hopefully to provide reference for further research and instruction.
An Assessment of the Challenges affecting Smallholder Farmers in Adopting Biogas Technology in Zambia
Authors: Kalinda Thomson
Published: May 2019

The objective of this study was to assess the challenges of adopting biogas technology among rural households in Zambia. Three hundred and twenty households with and without biodigesters were selected randomly from five provinces in the country for the study. A household survey and qualitative methods such as focus group discussions and key interviews were used to collect information. The results show that firewood and charcoal are the main sources of cooking energy in the study areas despite the enormous potential for the utilization of biogas. The use of biogas technology is in its infancy and few households have adopted the technology. The study found that several challenges or factors were responsible for the low adoption status of biogas technology in the study areas. The main challenges were the high cost of installation of biodigesters; lack or limited access to credit to help meet the costs of construction of biodigesters; inadequate numbers of skilled biodigester technicians; and lack of awareness or limited information on biogas technology. Increasing access to affordable credit, as well as awareness raising on biogas technology among rural households are suggested as some of the ways that will assist to promote the adoption of biogas technology as a sustainable renewable energy source for rural populations in Zambia.

The European and Russian Far Right as Political Actors: Comparative Approach
Authors: Ekaterina Ivanova , Andrey Kinyakin , Sergey Stepanov
Published: May 2019

The article is devoted to the comparative analysis of the far right (nationalist) as political actors in Russia and in Europe. Whereas the European far-right movements over the last years managed to achieve significant success turning into influential political forces as a result of surging popular support, in Russia the far-right organizations failed to become the fully-fledged political actors. This looks particularly surprising, given the historically deep-rooted nationalist tradition, which stems from the times Russian Empire. Before the 1917 revolution, the so-called «Black Hundred» was one of the major far-right organizations, exploiting nationalistic and anti-Semitic rhetoric, which had representation in the Russian parliament – The State Duma. During the most Soviet period all the far-right movements in Russia were suppressed, re-emerging in the late 1980s as rather vocal political force. But currently the majority of them are marginal groups, partly due to the harsh party regulation, partly due to the fact, that despite state-sponsored nationalism the position of Russian far right does not stand in-line with the position of Russian authorities, trying to suppress the Russian nationalists. This is sharply contrasting with the situation with the far right in Europe, which are more well-established and institutionalized as political actors, using conventional forms of political activity. However, despite some differences with the European counterparts, the Russian far right have obvious potential as political actors, which can be realized under certain circumstances, enabling them to play more significant in the political system of Russia.

$ \pi $ at the limits of computation
Authors: Hwang Chien-Lih
Published: May 2019

Before 1976, all record-broken computation for the digits of $ \pi $ completely depended on arctangent-type identities; of them the most celebrated is John Machin's identity ${ \pi\over 4}=4\tan^{-1} ({1\over 5})\-tan^{-1}({1\over 239})$, discovered in 1706. But, in 1976, Eugene Salamin moved in a powerful heavy artillery. The method is an adaptation of an algorithm discovered by Gauss for the evaluation of elliptic integrals. Then, a new era comes. In 1983, Y.~Kanada, Y.~Tanura, S.~Yoshino and Y.~Ushiro used Gauss-Legendre-Brent-Salamin algorithm to calculate $ \pi $ to $2^{24}$ (16,777,216) decimal places on a HITAC M-280H supercomputer and used an FFT-based fast multiplication. In this article, we present an easy-to-understand explanation of this amazing method.

Pau és un enfoc educatiu que té per objectiu la construcció d'una ciutadania crítica i compromesa amb la transformació social en claus de justícia, sostenibilitat i solidaritat i connexió amb les problemàtiques globals. Hemdesenvolupat una seqüència
didàctica que, partint d'una proposta clàssica de treball d'elaboració d'una dieta sana, promou la connexió del node de l'alimentació amb diverses problemàtiques globals, com la justícia social i el canvi climàtic. Fem una descripció de la seqüència
i els resultats d'aplicació i considerem les possibilitats de transformació d'activitats d'ensenyament de les ciències amb enfocs similars com a aportació a la Cultura del Desenvolupament i la Pau.

Este artigo tem como objetivo identificar os principais fatores que influenciam na qualidade vida do trabalho e analisar as principais estratégias de enfretamento as dimensões de estresse ocupacional em funcionários de Tecnologia da Informação (TI). Foram utilizados como instrumentos de pesquisa um questionário sociodemográfico, o questionário desenvolvido por Adrianni (2012) para Qualidade de Vida no trabalho, e o questionário para estresse no trabalho, Job Stress Scale, desenvolvido por Alves (2012). Participaram do estudo 44 profissionais de Tecnologia da Informação com idades entre 18 e 60 anos. A pesquisa foi realizada no departamento de tecnologia de informação de uma instituição bancária que possui sede no Estado de Sergipe. Como resultados, perceberam-se que os participantes concordam razoavelmente que os fatores suportem à execução do trabalho, relacionamento e respeito profissional influenciam positivamente em sua qualidade de vida no trabalho, e concordam intensamente que o fator programa de qualidade de vida no trabalho influencia diretamente nesse fenômeno. As recompensas oferecidas pela organização foi um ponto dissonante, no que tange a qualidade de vida. Os resultados também apontam que os participantes não possuem uma alta média fatorial para demanda psicológica, além de apontarem para a existência de bons relacionamentos entre colaboradores e chefia, e para um apoio social satisfatório, o que influencia no baixo índice de estresse ocupacional nos resultados da pesquisa.

Authors: Simon Teresa A. , Soule Benjamin P. , Hochberg Marc , Fleming Douglas , Torbeyns Anne , Banerjee Subhashis , Boers Maarten
Published: May 2019

Objective

To assess the safety of abatacept treatment in rheumatoid arthritis (RA) using integrated data from multiple clinical trials.

Methods

Data from nine double‐blind, placebo‐controlled studies of abatacept treatment (seven intravenous, two subcutaneous) in patients with RA were pooled, focusing on safety events in the double‐blind treatment period of each study. Incidence rates (IRs) of adverse events (AEs) per 100 patient‐years of exposure were calculated for abatacept‐ and placebo‐treated patients. AEs in abatacept‐treated patients were combined regardless of dose and formulation.

Results

In total, 2653 patients received abatacept and 1485 received placebo, with 2357 and 1254 patient‐years of exposure, respectively. The mean (SD) durations of exposure in the abatacept and placebo groups were 10.8 (3.3) and 10.3 (3.5) months, respectively. The IRs (95% confidence interval [CI]) for serious AEs were 14.8 (13.3, 16.5) and 14.6 (12.5, 17.0) in the abatacept and placebo groups, respectively. Death occurred in 12 (0.5%) and 12 (0.8%) patients in the abatacept and placebo groups, respectively, and was most commonly caused by cardiac disorders. Malignancies were observed in 31 patients (1.2%) treated with abatacept (IR: 1.32 [95% CI: 0.90, 1.87]) versus 14 (0.9%; IR: 1.12 [0.61, 1.88]) who received placebo. Solid organ tumor was the most frequent malignancy reported in both groups (abatacept: 1.0%; IR: 1.11 [95% CI: 0.72, 1.62]; placebo: 0.8%; 0.96 [0.50, 1.67]).

Conclusion

In this integrated analysis, the IRs of safety events in the abatacept and placebo groups were similar with no new safety concerns identified.
