Published: April 2019

CD4 T cell activation is critical to the initiation of adaptive immunity. CD4 T cells are also the main targets of HIV infection, and their activation status contributes to the maintenance and outcome of infection. Although the role of activation in the differentiation and proliferation of CD4 T cells is well studied, its impact on the processing and MHC class I (MHC-I) presentation of epitopes and immune recognition by CD8 T cells are not investigated. In this study, we show that the expression and hydrolytic activities of cellular peptidases are increased upon TCR-dependent and MHC–peptide activation of primary CD4 T cells from healthy or HIV-infected persons. Changes in peptidase activities altered the degradation patterns of HIV Ags analyzed by mass spectrometry, modifying the amount of MHC-I epitopes produced, the antigenicity of the degradation products, and the coverage of Ags by degradation peptides presentable by MHC-I. The computational analysis of 2237 degradation peptides generated during the degradation of various HIV-antigenic fragments in CD4 T cells identified cleavage sites that were predictably enhanced, reduced, or unchanged upon cellular activation. Epitope processing and presentation by CD4 T cells may be modulated by the activation state of cells in a sequence-dependent manner. Accordingly, cellular activation modified endogenous Ag processing and presentation and killing of HIV-infected CD4 T cells by CD8 T cells in a way that mirrored differences in in vitro epitope processing. The clearance of HIV-infected cells may rely on different immune responses according to activation state during HIV infection.

Here we report the different therapeutic approaches in 4 cases of elderly patients with AHA and co-morbidities.
Incidental papillary thyroid cancer diagnosis in patient with adult-onset Still’s disease-like manifestations
Authors: Tirri R. , Capocotta D.
Published: April 2019

Adult onset Still’s disease (AOSD) is a systemic inflammatory disease characterized primarily by a triad consisting of daily fever, arthritis and maculopapular exanthema. The pathogenesis and etiology of AOSD are unknown and the diagnosis, which can be very challenging, is often made by exclusion. Here, we report a case of a 61-year-old woman with a history of mild psoriatic arthritis, fever, arthritis and maculopapular exanthema. Her initial laboratory tests showed neutrophilic leukocytosis, hypertransaminasemia, and markedly elevated levels of the erythrocyte sedimentation rate and C-reactive protein. With a presumptive diagnosis of AOSD, based on Yamaguchi criteria, the patient started an extensive diagnostic work-up to exclude other potential differential diagnoses. With fluorodeoxyglucose (FDG) positron-emission tomography, a thyroid nodule with moderate FDG uptakes was detected. The fine needle aspiration biopsy led to diagnosis of papillary thyroid cancer. The history of psoriatic arthritis, the patient’s age, and atypical features of the skin rash described as not concomitant with fever flares, suggested a diagnosis of paraneoplastic AOSD-like manifestations.

Concussion and National Hockey League Player Performance: An Advanced Hockey Metrics Analysis
Authors: Buckley Thomas A. , Bryk Kelsey N. , Van Pelt Kathryn L. , Broglio Steven P. , East Stephen A. , Zuckerman Scott L. , Kuhn Andrew W.
Published: April 2019

Context

Postconcussion deficits in neurocognitive performance and postural control may persist at the time of return to sport participation. How these deficits, if present, affect athletic performance is largely unknown, with prior studies showing mixed results.

Objective

To evaluate postconcussion National Hockey League player performance using advanced hockey metrics over short- (5 games), medium- (10 games), and long-term (remainder of the season) seasonal performance.

Design

Retrospective cohort study.

Patients or Other Participants

National Hockey League players who sustained a sport-related concussion (SRC; n = 93) and returned during the same season and players (n = 51) who missed time for non–injury-related reasons.

Main Outcome Measure(s)

Six performance metrics were used: (1) points per 60 minutes, (2) Corsi percentage, (3) personal Fenwick shooting percentage, (4) scoring chances per 60 minutes, (5) penalty difference, and (6) PDO (not an acronym but sometimes referred to as SVSP% [save percentage shooting percentage]). Performance was compared using 2 (group) × 2 (time) repeated-measures analyses of variance for 3 time windows: (1) ±5 games, (2) ±10 games, and (3) the remainder of the season postconcussion. Alpha values were set at a conservative .01 to account for the lack of independence among dependent variables.

Results

No significant interactions were present for any of the 6 dependent variables at any of the 3 time windows. Overall, none of the secondary variables differed.

Conclusions

Using advanced, sport-specific metrics, we found that National Hockey League players did not display worse seasonal performance during 3 postinjury time frames after they sustained an SRC. Whereas laboratory studies have identified lingering neurologic deficits after concussion, our results suggest that these deficits, if present, either do not translate to worse athletic performance or were not captured by these 44 metrics. Further, prospective efforts are needed to accurately quantify performance after SRC among professional hockey players.

Published: April 2019

O ensaio propõe reflexões sobre as estratégias usadas por Funakoshi para modernizar o karatê na era Meiji. Os resultados mostram que, ao deslocar o sentido da prática do karatê para ajustá-lo aos valores ocidentais, o Mestre abdicou do sentido tradicional do budo para investir numa via de formação onde a morte simbólica emerge como prioridade. Isso contribuiu para acelerar a desconstrução da imagem do samurai real e do bushido na modernidade. Funakoshi garantiu a sobrevivência da arte marcial, mas abriu caminhos para a emergência de éticas mitigadas e práticas não convencionais no karatê.

Published: April 2019

Este artigo tem como objetivo compreender os elementos que constituem o processo de socialização docente de professores de Educação Física iniciantes na carreira docente. Para tanto, foi realizada uma pesquisa etnográfica com dois professores de Educação Física, em duas escolas da Rede Municipal de Ensino de Porto Alegre/RS. Utilizamos como instrumentos de obtenção de informações o diário de campo e a entrevista semiestruturada. Neste estudo, compreendemos a socialização docente como um processo, constituída por uma tríade: identidades, cultura escolar e subjetividades. Compreendemos também que a socialização docente é um fenômeno complexo, não linear e que se constrói em momentos de individualização e em momentos de coletividade, de forma dialética. Estudar esse processo significou compreender os tempos e espaços de cada sujeito envolvido e, ainda, o seu meio social.

Published: April 2019

Em 2005, o Ministério do Esporte criou o Programa Bolsa Atleta como apoio aos atletas para se dedicarem aos treinamentos e competições locais. Após essa iniciativa do Governo Federal, identificamos ações semelhantes no âmbito universitário, sobretudo nas Universidades federais. Diante desse diagnóstico, esse artigo se propõe analisar preliminarmente o Programa Bolsa Atleta Universitária da Universidade de Brasília (PBA-UnB) no período de 2011 a 2015. Parametrizado pela abordagem teórico-metodológica crítico-dialética, adotamos os procedimentos de levantamento documental e pesquisa bibliográfica. Para análise dos dados coletados utilizamos aspectos e indicadores do modelo analítico de políticas sociais de Boschetti, (2009). Os resultados iniciais demonstram que PBA-UnB possui abrangência restrita e atendimento focalizado, mas com potencial de ampliação. Observa-se que o programa oscila entre a hegemonia dos padrões de avaliação do esporte de rendimento e o alinhamento à política universitária e ao papel democrático e inclusivo da Universidade pública.
Rhetorically decentralised, practically recentralised: a review of the local governance system of Ghana
Authors: Anaafo David
Published: April 2019

There is currently a global quest to decentralise government functions, which has resonated well with many developing countries. Ghana has over the last few decades embraced decentralisation in principle, as a way of promoting inclusive, efficient, accountable and bottom-up local-level governance. However, it is unclear how successfully this vision is being achieved.  Using a heuristic continuum as an analytical framework, this study conducted a literature- and statute-based politico-administrative review of the local governance system of Ghana to ascertain the extent of decentralisation. The study concludes that the legislative, political and administrative arrangements in place make it easy for the centre to usurp the powers of local authorities.

Abstract. The effect of black carbon (BC) on air quality and the climate is still unclear, which is partly because of the poor understanding regarding the BC aging process in the atmosphere. In this work, we developed a new approach to simulate the BC mixing state (i.e., other species coated on the BC surface) based on an emissions inventory and back-trajectory analysis. The model tracks the evolution of the BC aging degree (characterized by the ratio of the whole particle size and BC core) during atmospheric transport. Using the models, we quantified the mass-averaged aging degree of total BC particles transported to a receptor (e.g., an observation site) from various emission origins (i.e., 0.25° × 0.25° grids). The simulations showed good agreement with the field measurements, which validated our model calculation. Modeling the aging process of BC during atmospheric transport showed that it strongly dependent on emission levels. BC particles from extensive emission origins (i.e., polluted regions) were characterized by a higher aging degree during atmospheric transport due to more co-emitted coating precursors. On the other hand, high-emission regions also controlled the aging process of BC particles that were emitted from cleaner regions and passed through these polluted regions during atmospheric transport. The simulations identified the important roles of extensive emission regions in the BC aging process during atmospheric transport, implying the enhanced contributions of extensive emission regions to BC light absorption. This revealed that emission reductions in polluted regions could achieve more benefits for improving air pollution and climate change. Emission reductions in polluted regions not only decreased the aging degree of BC emitted from these regions but also reduced the aging process of BC emitted from other origins during atmospheric transport. Moreover, emissions reduction in polluted regions may be more efficient in counteract the suppression of planetary boundary layer (PBL) by BC particles (e.g., Zdunkowski et al., 1976; Jacobson, 1998; Wendisch et al., 2008; Barbaro et al., 2013; Ding et al., 2016; Wang et al., 2018), because a greater decrease in the BC aging degree during atmospheric transport would weaken the light absorption capability of BC in the upper PBL. The simulation of the BC aging degree during atmospheric transport provided more clues for improving air pollution and climate change.

However, their formation and growth are not fully understood, and multiple in-situ aircraft campaigns have observed frequent and persistent apparent water vapor supersaturations of 5 %–25 % in ultracold cirrus (T
Toward an open-access of high-frequency lake modelling and statistics data for scientists and practitioners. The case of Swiss Lakes using Simstrat v2.1

Published: April 2019

Abstract. One-dimensional hydrodynamic lake models are nowadays widely recognized as key tools. They offer the possibility to study processes at high frequency, here referring to hourly time scale, to analyse scenarios and test hypothesizes. Yet, simulation outputs are mainly used by the modellers themselves and often not easily reachable for the outside community. We have developed an openly accessible web-based platform for visualization and promotion of easy access to lake model output data updated in near real time (https://simstrat.eawag.ch/). This platform was developed for 54 lakes in Switzerland with potential for adaptation to other regional areas or even at global worldwide scale using appropriate forcing input data. The benefit of this data platform is here practically illustrated with two examples. First we show that the output data allows for assessing the long term effects of past climate change on the thermal structure of a lake. In the second case, we demonstrate how the data platform can be used to study and compare the role of episodic strong wind events for different lakes on a regional scale and especially how they temporary destabilize their thermal structure. With this open access data platform we demonstrate the path forward for scientists and practitioners promoting a cross-exchange of expertise through openly sharing of in-situ and model data.
La ayuda oficial al desarrollo y el contexto institucional como factores de crecimiento y progreso: casos comparados de Honduras y Costa Rica
Authors: Benito del Pozo Paz , Corcoba Carolina
Published: April 2019

La evolución de los países pertenecientes a espacios o regiones en desarrollo ofrece un cuadro de situaciones y de tendencias que ponen de manifiesto la existencia de fuertes contrastes geopolíticos y de gobernanza entre unos y otros. En América Latina, países con características similares, localizados en una misma zona geográfica y que han compartido tanto procesos históricos generadores de desigualdad (proceso colonización/descolonización), como raíces de marcado sesgo sociocultural (mundo hispánico), que actúan como elemento de identidad,  muestran hoy una dinámica con evidentes contrastes en cuanto a modelo socioeconómico, nivel de desarrollo y oportunidades para progresar. Honduras y Costa Rica, los dos casos empíricos objeto de este análisis, ilustran situaciones de esa disparidad y permiten extraer lecciones geopolíticas. Como premisa, se acepta que el éxito o fracaso de estos países depende del tipo de instituciones que dan soporte a su estructura política y económica, pues según sean inclusivas o extractivas pueden a impulsar o bloquear el desarrollo, de acuerdo con  la Teoría de las Élites Extractivas. En este contexto, la Ayuda Oficial al Desarrollo (AOD)  puede llegar a ser un factor de notable influencia, pero su eficacia dependerá de cómo se gestione por parte de las instituciones nacionales que la reciben, además de los criterios que la motivan, los sectores a los que se aplica y los intereses/implicación de los donantes. Los resultados obtenidos alumbran una realidad compleja que no contraviene los planteamientos ni favor ni en contra de la AOD, lo que deja abierto el debate, pero sí sugieren la necesidad de planificar y  equilibrar los intereses de donantes y receptores.
La cooperación internacional para la paz en Colombia: los casos de Estados Unidos y de la Unión Europea (1998-2016).
Authors: Agudelo Taborda Jairo , Riccardi Davide
Published: April 2019

Desde los fallidos diálogos del Caguán entre FARC-EP y Gobierno colombiano (1998-2002) hasta la firma y refrendación de los Acuerdos de La Habana (2016), Colombia vivió un intenso acompañamiento internacional en su búsqueda de la paz negociada. Mediante un análisis estadístico y documental se constata que, durante este período, los recursos de la cooperación internacional provinieron, casi en su totalidad, de los dos socios más importantes de Colombia: Estados Unidos y la Unión Europea. El primer actor, privilegiando un componente militar; el segundo, basado únicamente en ayuda civil. Estas dos diferentes, y a veces opuestas, políticas de cooperación para la paz, reflejan distintos intereses tanto de los donantes (EE UU y UE) como de los demandantes (el Estado colombiano y su sociedad civil). Sin embargo, las dos distintas cooperaciones convergen en torno a los diálogos de La Habana (2012-2016) que, con la firma de los acuerdos proyectaron a Colombia hacia un nuevo e inédito escenario: el “posconflicto”, mejor llamado “posacuerdo”. Es precisamente esta convergencia de los dos grandes enfoques hegemónicos de la cooperación internacional la que hace de Colombia un país sui generis en escenarios de conflicto y de transición hacia posconflictos que podría ser representativo para otros contextos geográficos, alimentando y ampliando, el debate entre “paz liberal” y “paz posliberal” para futuras investigaciones específicas sobre el tema.

World Christianity: A Genealogy
Authors: Irvin Dale T.
Published: April 2019

The field of world Christianity has received considerable scholarly attention in recent years. Some have claimed it is a new field of study, while others have reduced it to mission studies. This article argues that the genealogy of world Christianity lies in the twentieth-century ecumenical movement and especially in the manner in which that movement brought together the search for unity, mission, and interreligious dialogue. The article argues that these three areas of academic scholarship together continue to shape the wider field of study we call world Christianity today.
The Study of World Christianity Past, Present, and Future: History, Theology, Social Sciences, and Beyond
Authors: Zurlo Gina A.
Published: April 2019

Most scholars know that world Christianity is inherently interdisciplinary, that it can be studied from different methodological perspectives. While world Christianity is often studied through historical and theological lenses, the application of the social sciences—in particular quantitative methods—is a little more fuzzy. This article looks backward and forward to reflect on methodological approaches to studying world Christianity. Looking backward, it highlights the work of missionary statistician David Barrett as it developed for the World Christian Encyclopedia. The Encyclopedia provided an intellectual framework for reconstructing Christianity in a world after colonialism. Looking forward, the article offers some thoughts on why it is not always clear how to incorporate quantitative social science into world Christianity studies and looks genealogically at the history of “Christian” sociology in the late nineteenth and early twentieth centuries. The article concludes with a methodological challenge for world Christianity scholars.
Entangled Genealogies and False Dichotomies: Anthropology, Theology, and the Post-secular Paradigm in World Christianity
Authors: Richman Naomi Irit
Published: April 2019

In this article, the author sheds light on some of the methodological challenges that currently face scholars in world Christianity by mapping out genealogically how ontology has come to be a concern for those pursuing social scientific approaches to the study of Christianity in particular. By unraveling some of the guiding theoretical principles of the study of religions more generally, the author reveals the conditions that have ultimately rendered the “problem of belief” in fact a “problem” for (purportedly) secular explorations of Christian cultures. The author reflects upon the theoretical principles of an emerging group of anthropologists of Christianity who are seeking to address the problems raised by their secular orientations and cultivating what is fast becoming known as a “theologically engaged anthropology.” From there, she offers some of her own solutions to these predicaments and suggests some useful theoretical approaches for those scholars working in world Christianity going forward.
Similar Objects, Divergent Approaches: What Can World Christianity Learn from the Anthropology of Christianity?
Authors: Seat II Thomas
Published: April 2019

The author argues that even though its scholars have a broad range of methods and epistemologies, the interdisciplinary field of world Christianity, on the whole, has a theological orientation. Consequently, world Christianity scholars often consider divine actions in conversion. Yet the author contends that their accounts of human action in conversion are typically underdeveloped. By contrast, methods that anthropologists of Christianity employ lead them not to theologize about divine actions, but to observe human actions, offering context-specific conversion accounts. Theorizing conversion almost exclusively in terms of human agency, their treatments of human actions are rather thorough. If world Christianity scholars are to offer comprehensive conversion accounts, they must pay more attention to roles Christians play in their own conversion, and the anthropology of Christianity can be instructive. While theological and empirical methods could be combined, methodological difficulties may arise—yet using empirical approaches can still offer fuller accounts of human action.
Complex Currents, Contemporary Perspectives, and Converging Methods: A Review of the Graduate Student Research Panel at Princeton Theological Seminary’s 2018 World Christianity Conference
Authors: Law Easten
Published: April 2019

During Princeton Theological Seminary’s 2018 conference on currents, perspectives, and methodologies in world Christianity, organizers invited doctoral students to present short abstracts on their dissertation projects. Their research offers us a window into the future of world Christianity as an academic field. This article reviews a sample of the presented projects, exploring what new questions, methods, and patterns of thought are animating the next generation of world Christianity scholars, including (1) a new sensitivity to the bricolaged nature of culture in a globalized and postmodern era, (2) an orientation toward contemporary concerns in the humanities and social sciences, and (3) increased experimentation with multiple methods and disciplinary perspectives.
Relativistic disks with two charged perfect fluids components

A method to describe exact solutions of the Einstein-Maxwell field equations in terms of relativistic thin disks constituted by two perfect charged fluids is presented. Describing the surface of the disk as a single charged fluid we find explicit expressions for the rest energies, the pressures and the electric charge densities of the two fluids. An explicit example is given. The particular case of the thin disks composed by two charged perfect fluids with barotropic equation of state is also presented.
Remarks on QFT in the Coordinate Space
Authors: Much A.
Published: April 2019

Generators of the Poincaré group, for a free massive scalar field, are usually expressed in the momentum space. In this work we perform a transformation of these generators into the coordinate space. This (spatial)-position space is spanned by eigenvectors of the Newton-Wigner- Pryce operator. The motivation is twofold. First, we want to investigate the localization of a relativistic particle. Furthermore, we need a deeper understanding of the commutative spatial coordinate space in QFT, in order to investigate the non-commutative version thereof.

Foram selecionados seis diferentes pontos do fluxograma de produção de planta de processamento de pequeno porte e coletadas 20 amostras de diferentes lotes para a realização das análises microbiológicas, totalizando 120 amostras. Todas as amostras foram submetidas à pesquisa de Salmonella e NMP de coliformes a 35°C e 45°C, com exceção dos condimentos, onde foi pesquisada apenas a presença do patógeno. Além disso, nas amostras coletadas após a defumação, foi aferido o pH. Durante o processo de produção, a contaminação por coliformes decresceu e Salmonella foi isolada em todos os pontos do fluxograma, com exceção da carcaça. O ponto onde houve maior contaminação foi após a cura, onde 35% das amostras foram positivas. Amostras de condimentos e salames após o embutimento apresentaram 20% de positividade e carne moída e produto final apresentaram 10% e 5%, respectivamente. Verificou-se que houve a disseminação do patógeno durante a produção de salame e este fato ocorreu principalmente por falhas no processamento do alimento além de procedimentos inadequados de higienização utilizados durante as operações de produção, sendo esta etapa fundamental para a obtenção de alimentos com qualidade microbiológica e que não ofereçam riscos de veiculação de patógenos.

The conclusion as to the applied effectiveness of the established system of rehabilitation is made after comparing the expected results of the rehabilitation and rehabilitation with the real achievements, carrying out a detailed analysis of the implemented individual programs at each stage of the restoration of consciousness, as well as clarifying the design of daily exercises and the principles of the distribution of loads in order to solve the set clinical problems, and both general and current goals.
Artificial intelligence for software development — the present and the challenges for the future
Authors: Korzeniowski Łukasz , Goczyła Krzysztof
Published: April 2019

Since the time when first CASE (Computer-Aided Software Engineering) methods and tools were developed, little has been done in the area of automated creation of code. CASE tools support a software engineer in creation the system structure, in defining interfaces and relationships between software modules and, after the code has been written, in performing testing tasks on different levels of detail. Writing code is still the task of a skilled human, which makes the whole software development a costly and error-prone process. It seems that recent advances in AI area, particularly in deep learning methods, may considerably improve the matters. The paper presents an extensive survey of recent work and achievements in this area reported in the literature, both from the theoretical branch of research and from engineer-oriented approaches. Then, some challenges for the future work are proposed, classified into Full AI, Assisted AI and Supplementary AI research fields.

Authors: Suproniuk Marek , Paś Jacek
Published: April 2019

In Poland, approx. 95% of electrical energy is generated in a coal combustion process. Saving electrical energy gives economic effects related to the smaller fees and contributes to protection of the natural environment. Additionally, saving electrical energy should translate into our health, lesser degradation of the natural environment, or less consumption of natural deposits of energy. The paper has presented the issues related to analysis of energy consumption in a selected building object. The analyse includes the following issues − document analysis related to the building’s power, energy distribution, and power consumption of individual load and time regimes of work of receivers in the object and analysis of electrical energy which has been measured in a building.
Keywords: electricity quality parameters measurement, higher harmonics of current/voltage.
Numerical analysis of interaction between a model tunnel lining and non-cohesive soil
Authors: Szklennik Paweł
Published: April 2019

The paper presents an analysis and assessment of an interaction between a model tunnel lining and surrounding non-cohesive soil. The analysis was conducted with numerical simulations using the author’s program based on an algorithm of the discrete element method. Previously calibrated numerical model was used in the calculations. Calibration was based on comparison of the construction deformations observed in the laboratory tests and during the simulation. Numerous simulations, performed in the calibrated numerical model, included calculations for a flexible and rigid construction of the lining. The tunnel construction loads, stress distribution in the surrounding soil, and soil particles’ displacements were investigated. Analyses were conducted in two variants — when only soil weight is acting on the tunnel construction and when the external load transmitted from the surface is present. Also two variants of the backfill height were investigated — they were equal to one and two diameters of the tunnel. The values of tunnel loads, which were numerically calculated, were compared with the corresponding values, calculated by the Hewett’s method. It is shown that distribution of tunnel loads and stresses in the surrounding soil is strongly linked with the tunnel construction stiffness, thus it can be significantly different from standard load situations for such constructions.
Keywords: civil engineering, discrete element method, tunnel lining
Influence of tensile softening of concrete on crack development and failure in concrete and reinforced concrete beams
Authors: Słowik Marta
Published: April 2019

In the paper, the own test results were presented. The experimental investigation was focused at determining the cracking and load capacity of beams made of concrete. The beams were characterized by different longitudinal reinforcement ratio from zero — plain concrete beams, through low ratio 0.12% — slightly reinforced concrete beams, middle ratio 0.9% — typical reinforced concrete beams, up to the ratios 1.3% and 1.8% — higher reinforced concrete beams. On the basis of the performed experiments and the results of numerical calculations, the process of crack’s formation and crack’s development in plain concrete, slightly reinforced concrete and reinforced concrete beams with different reinforcement ratio was described. When discussing cracking process in the beams, the contribution of strain softening of tensile concrete in the microcracked zone on the character of beams’ failure was analysed as well.
Keywords: civil engineering, concrete and reinforced concrete members, cracking and load capacity.
