Preparing the milk and honey: between ethnography and academia as a racially minoritised academic
Authors: Khan Kamran
Published: April 2018

This paper focuses on the development of an academic of colour between ethnographic fieldwork and becoming an academic. In terms of data collection, this study demonstrates the complexities and multiple positionalities ascribed and assumed within fieldwork which question the stability of the insider/outsider dichotomy. These positionalities range from being a Muslim ‘brother’ to being aligned with Government security. Being Muslim and male also allowed for entrance in areas of the field which were exclusively for Muslim males. While fieldwork presented certain complexities, being a person of colour and Muslim in academia presents many more. A number of studies have demonstrated the structural whiteness of academia and thus, dealing with this as an academic of colour require particular skills and actions. I share my experiences of navigating academia as a person of colour and question the role of whiteness within ethnographically oriented representative groups which are exclusively white and who represent an academic audience for ethnographic scholarship.

Published: April 2018

This paper presents a review on retinal gliosis illustrated by series of three cases of patients (a 39-year-old man and a 35-year-old woman with massive retinal gliosis (MRG) and a 51-year-old man with truly focal nodular gliosis of retina) with intraocular tumor-like masses and loss of vision, who recently suffered from painful inflammation of eyeball and who classically had a history of remote ocular trauma, onset of blindness early in lifetime or gradual but progressive loss of sight. The diagnosis of this pathological entity is given for the lesions that are composed of GFAP strongly positive, elongated, fusiform cells consistent with fibrillary astrocytes. As illustrated in cases from our pathological practice, PAS gave positive patchy disseminated reaction in form of cellular densely purplish granules in minority of cells representing glycogen storing. This feature could be consistent with PAS-positive Müller cells that also constitute retinal gliosis as one of cellular components of normal retina that is induced to reactive proliferation. Thus, the paper presents histological background and differential diagnosis of the entity.
Overcoming SMEs Financing and Supply Chain Obstacles by Introducing Supply Chain Finance
Authors: Abbasi Waseem Ahmed , Wang Zongrun , Alsakarneh Asaad
Published: April 2018

Keeping in view the importance of small and medium enterprises (SMEs) for the growth of a nation, we must also keep an eye on the challenges faced by those SMEs. There are various kinds of financing and supply chain options available for SMEs but they still face lot of hindrances. This paper would help us to understand why SMEs are important for the development of any country and how could we help the SMEs from facing challenges related to financing and supply chain. This study further highlights the key financing issues faced by SMEs and also focuses on major supply chain challenges confronted by the SMEs. This study put emphasis on the concept of supply chain finance (SCF) and that how SCF could help SMEs to overcome those challenges. In addition, this paper also points out the benefits and prospects of SMEs. Even though the concept of SCF is still in developing phase but it has shown significant assistance to SMEs in order to grow further.
Xanthii fructus inhibits malignant behaviors of lung cancer cells
Authors: Zhen-fei Wang , Yong-ping Mu , Jun-qing Liang , Yong-yan Liu , Jing-quan Li
Published: April 2018

Objective

This study aimed to investigate the influence of Xanthii fructus on the expression of small noncoding RNA (sncRNA) and the malignant behaviors of lung cancer cells.

Method

A549 cells were treated with Xanthii fructus extract. SncRNA expression was detected by real-time PCR. Proliferation, anchorage-independent growth, and invasion capacities were determined using Cell Counting Kit (CCK)-8, soft agar colony formation, and Matrigel assays, respectively.

Results

Xanthii fructus extract downregulated microRNA (miR)-21 expression and upregulated PIWI-interacting RNA (piRNA)55490 expression. The proliferation, anchorage-independent growth, and invasion capacities of A549 cells were strongly inhibited by the extract.

Conclusion

Xanthii fructus can inhibit the malignant behaviors of lung cancer cells.
Dehydrogenation of Propane to Propylene with Highly Stable Catalysts of Pt-Sn Supported Over Mesoporous Silica KIT-6
Authors: Ruelas-Leyva Jose P. , Mata-Martinez Alejandro , Talavera-López Alfonso , Gómez Sergio A. , Jimenez-Lam Sergio A. , Fuentes Gustavo A.
Published: April 2018

During several reactions, similar to dehydrogenation of propane to propylene, coke is one of the main reasons for the catalyst deactivation. The coke formation and further deactivation of the catalyst are strongly dependent to the active site in the catalyst and/or the properties of the support. KIT-6 with interconnected porous and high surface area can handle with the coke formation, and can disperse easily the deposited Pt nanoparticles. In this sense, a series of Pt-Sn/KIT-6 catalysts were synthesized with distinct Sn loadings and used in the dehydrogenation of propane. The performance of these catalysts during reaction varied with the Sn loading. The specific activities for propylene formation obtained with the catalysts were comparable to the best result reported in the literature. The nanoparticles present in the catalyst through pretreatment and reaction condition was the Pt-Sn alloy (1:1 atomic ratio), and that alloy is suggested to be the active phase. This Pt-Sn alloy was stable during the entire reaction time, that even in two catalysts containing a considerable amount of coke, deactivation was not observed. Also, the support (KIT-6) with high connectivity helped to avoid deactivation by coke.
Neuro-Cognitive Effects of Acute Tyrosine Administration on Reactive and Proactive Response Inhibition in Healthy Older Adults

Published: April 2018

The aging brain is characterized by altered dopamine signaling. The amino acid tyrosine, a catecholamine precursor, is known to improve cognitive performance in young adults, especially during high environmental demands. Tyrosine administration might also affect catecholamine transmission in the aging brain, thereby improving cognitive functioning. In healthy older adults, impairments have been demonstrated in two forms of response inhibition: reactive inhibition (outright stopping) and proactive inhibition (anticipatory response slowing) under high information load. However, no study has directly compared the effects of a catecholamine precursor on reactive and load-dependent proactive inhibition. In this study we explored the effects of tyrosine on reactive and proactive response inhibition and signal in dopaminergically innervated fronto-striatal regions. Depending on age, tyrosine might lead to beneficial or detrimental neurocognitive effects. We aimed to address these hypotheses in 24 healthy older human adults (aged 61–72 years) using fMRI in a double blind, counterbalanced, placebo-controlled, within-subject design. Across the group, tyrosine did not alter reactive or proactive inhibition behaviorally but did increase fronto-parietal proactive inhibition-related activation. When taking age into account, tyrosine affected proactive inhibition both behaviorally and neurally. Specifically, increasing age was associated with a greater detrimental effect of tyrosine compared with placebo on proactive slowing. Moreover, with increasing age, tyrosine decreased fronto-striatal and parietal proactive signal, which correlated positively with tyrosine’s effects on proactive slowing. Concluding, tyrosine negatively affected proactive response slowing and associated fronto-striatal activation in an age-dependent manner, highlighting the importance of catecholamines, perhaps particularly dopamine, for proactive response inhibition in older adults.
Scales of seafloor sediment resuspension in the northern Gulf of Mexico

Published: April 2018

Seafloor sediment resuspension events of different scales and magnitudes and the resulting deep (>1,000 m) benthic nepheloid layers were investigated in the northern Gulf of Mexico during Fall 2012 to Summer 2013. Time-series data of size-specific in-situ settling speeds of marine snow in the benthic nepheloid layer (moored flux cameras), particle size distributions (profiling camera), currents (various current meters) and stacked time-series flux data (sediment traps) were combined to recognize resuspension events ranging from small-scale local, to small-scale far-field to hurricane-scale. One small-scale local resuspension event caused by inertial currents was identified based on local high current speeds (>10 cm s–1) and trap data. Low POC content combined with high lithogenic silica flux at 30 m above bottom (mab) compared to the flux at 120 mab, suggested local resuspension reaching 30 mab, but not 120 mab. Another similar event was detected by the changes in particle size distribution and settling speeds of particles in the benthic nepheloid layer. Flux data indicated two other small-scale events, which occurred at some distance, rather than locally. Inertia-driven resuspension of material in shallower areas surrounding the traps presumably transported this material downslope leaving a resuspension signal at 120 mab, but not at 30 mab. The passage of hurricane Isaac left a larger scale resuspension event that lasted a few days and was recorded in both traps. Although hurricanes cause large-scale events readily observable in sediment trap samples, resuspension events small in temporal and spatial scale are not easily recognizable in trapped material as they tend to provide less material and become part of the background signal in the long-term averaged trap samples. We suggest that these small-scale resuspension events, mostly unnoticed in conventional time-series sampling, play an important role in the redistribution and ultimate fate of sediment distribution on the seafloor.
Growth hormone in combination with leuprorelin in pubertal children with idiopathic short stature

Published: April 2018

Objective

There is a scarcity of data from randomised controlled trials on the association of growth hormone (GH) with gonadotrophin-releasing hormone agonists in idiopathic short stature (ISS), although this off-label use is common. We aimed to test whether delaying pubertal progression could increase near-adult height (NAH) in GH-treated patients with ISS.

Methods

Patients with ISS at puberty onset were randomised to GH with leuprorelin (combination,n = 46) or GH alone (n = 45). NAH standard deviation score (SDS) was the primary outcome measure. The French regulatory authority requested premature discontinuation of study treatments after approximately 2.4 years; patients from France were followed for safety.

Results

Mean (s.d.) baseline height SDS was −2.5 (0.5) in both groups, increasing at 2 years to −2.3 (0.6) with combination and −1.8 (0.7) with GH alone. NAH SDS was −1.8 (0.5) with combination (n = 19) and −1.9 (0.8) with GH alone (n = 16). Treatment-emergent adverse events and bone fractures occurred more frequently with combination than GH alone.

Conclusion

Due to premature discontinuation of treatments, statistical comparison of NAH SDS between the two cohorts was not possible. During the first 2–3 years of treatment, patients treated with the combination grew more slowly than those receiving GH alone. However, mean NAH SDS was similar in the two groups. No new GH-related safety concerns were revealed. A potentially deleterious effect of combined treatment on bone fracture incidence was identified.

La publicación de este fascículo, número 19 del 2017, sobre la temática Historia y Trabajo Social, coincide con que durante este año se conmemoran varios hechos históricos que generaron transformaciones sociales, políticas, económicas y culturales significativas para Colombia; no obstante, en este espacio solo nos vamos a referir a dos de ellos, por lo que significaron y por su transcendencia para la comunidad académica y la sociedad. El primer hecho histórico hace referencia a los ciento cincuenta años de la fundación de la Universidad Nacional de Colombia, un acontecimiento que influyó en los debates para la construcción de la nación e incidió en el desarrollo de la educación superior en el país.La creación de la Universidad Nacional de Colombia hizo parte de las reformas propuestas por el liberalismo radical. Su fundación tenía como finalidad contribuir a las transformaciones sociales que requería el país, así como estructurar una propuesta educativa para una formación académica laica e independiente de los lineamientos confesionales de la Iglesia católica. En consecuencia, la Ley 66 del 22 de septiembre de 1867 dio origen a la Universidad con Manuel Ancízar como primer rector y uno de sus fundadores.
La Ciudadanía y los otros, en la primera mitad del siglo XIX en Colombia
Authors: Perilla Lozano Leonor
Published: April 2018

La condición de ciudadanía no la poseían todos los miembros de la república de Colombia en la primera mitad del siglo XIX. Una condición diferenciada, se definía por el hecho de ser hombres, mayores de edad, letrados y propietarios. El proyecto de construir una república estaba soportado, especialmente, en ideas de libertad e independencia.Documentos de asuntos criminales y de prensa, como contraparte a textos constitucionales y archivos del Congreso, nos posibilitan dar una mirada a la vida social y las reclamaciones frente a los abusos de autoridad, en la relación Estado-sociedad-individuo y nos muestran, además, la presencia de aquellos que no hacían parte del discurso oficial; los otros de la ciudadanía.

La intencionalidad de la intervención del Trabajo Social
Authors: Falla Ramírez Uva
Published: April 2018

La intervención profesional, desde los aportes de Max Weber, se considera como la acción con sentido subjetivo asignado por el actor, en este caso: el trabajador o la trabajadora social, a partir del cual se configuran los fines a lograr, las metas y la intencionalidad a alcanzar. A partir de allí se entienden las consideraciones de orden ético y político del trabajador o la trabajadora social, que están mediadas por las matrices teóricas o paradigmas que él o ella asume en la vida cotidiana. Explorar estos aspectos y plantear algunos temas de discusión, sin llegar a hacer una exegesis conclusiva, son los propósitos de este artículo.

Este artículo analiza las prácticas de bienestar laboral en Empresas Mendoza (1926-1990) -el grupo industrial más importante en la etapa de industrialización sustitutiva venezolana- y la contribución del Trabajo Social a estructurar y profesionalizar el más avanzado sistema asistencial empresarial desde mediados del siglo XX.La autonomía y dinámica alcanzada por las exponentes de esta profesión, sumadas a la puesta en práctica de acciones determinadas por los valores paternalistas y rentísticos de los directivos y las directivas de esta empresa, permitió conformar en el campo empresarial un espacio idóneo para su actividad e hizo posible que se emprendiera un interesante proceso de autocrítica y replanteamiento del Trabajo Social en Venezuela durante los años setenta.
La arteterapia como camino de transformación espiritual
Authors: Cáceres-Gutiérrez Juana M. , Santamaría-Osorio Laura P.
Published: April 2018

El abordaje de la arteterapia y la espiritualidad permite describir el significado simbólico y universal que el arte —a través de sus manifestaciones— puede brindar al espíritu, para alcanzar su transformación integral —personal y transpersonal—. Dicha transformación se comprende en el artículo desde un marco de intervención en patología o en disfuncionalidad, así como de promoción en salud y crecimiento personal. ¿Qué tiene el arte que transforma a los individuos? Se defiende la idea de que la relación terapéutica, el acto creativo y el self auténtico son los pilares de una fructífera intervención individual y social.
Debates contemporáneos sobre la pobreza: entre causas, representaciones y programas sociales
Authors: Mayorga Coy Angie
Published: April 2018

La pobreza puede considerarse como un problema social que genera diversas discusiones. Este artículo presenta una revisión documental de investigaciones elaboradas sobre la pobreza, ubicando los debates sobre la misma en tres tendencias: la primera, una visión científica que caracteriza la pobreza; la segunda, las representaciones sociales que existen sobre esta —estructurales, individuales o mágicas—; y, la tercera, los programas sociales para su intervención en Latinoamérica. De esta forma, se muestran convergencias y divergencias frente a los temas mencionados. Veremos que su intervención desde los programas de transferencias monetarias debe ser objeto de reflexión y, quizá, de un replanteamiento de la misma.
Intervención terapéutica en violencia contra las mujeres en Colombia
Authors: Martínez González Lina María
Published: April 2018

En este artículo se plantean reflexiones sobre el lugar inespecífico de la intervención terapéutica en las estrategias del Estado colombiano para enfrentar la violencia contra las mujeres en las relaciones de pareja. El interés se centra en la intervención profesional, concretamente en la terapéutica. Se reconoce que, pese al papel preponderante que tiene frente a las posibilidades de transformación de los imaginarios y las subjetividades que sostienen esta violencia, ocupa un lugar inespecífico dentro de las medidas definidas en la legislación, así como en las políticas públicas colombianas para enfrentarlas. Se destacan algunas perspectivas consideradas útiles por terapeutas para la construcción de estados de funcionamiento no violentos en las parejas.

Este artículo reflexiona sobre la función docente e investigadora del Trabajo Social y las consecuencias derivadas de la creciente jerarquización de los saberes, especialmente cuando las metodologías y epistemologías se relacionan con los estudios de las mujeres, de género y feministas en dicho campo de estudios. Basándonos en estrategias empoderadoras que algunas docentes hemos emprendido en España para superar las limitaciones del actual modelo de mercantilización científica, proponemos vincular el ámbito académico y el trabajo profesional para desarrollar investigaciones, redes interuniversitarias y estrategias científicas que contribuyan a revalorizar la producción de conocimientos desde esta alianza, resituando el valor del Trabajo Social como Ciencia Social.
Social Diagnosis
Authors: Joya Valbuena Daniela
Published: April 2018

El diagnóstico social es una de las obras pioneras del Trabajo Social, escrita en la primera mitad del siglo xx en los Estados Unidos, surge luego de varios años de trabajo de las Charity Organization Societies (cos) y de distintas agencias de asistencia social en este país. Dichas instituciones buscaban responder a los problemas sociales producidos por la industrialización y mejorar las condiciones de vida de obreros e inmigrantes provenientes de Europa.Cien años después de la primera edición y publicación de esta obra, el Trabajo Social ha recorrido un camino de profesionalización, de preguntarse sobre su ser y quehacer, replanteando constantemente su lugar en la sociedad desde diferentes perspectivas. En estas reflexiones, el trabajo de las pioneras norteamericanas y su obra han sido acogidos -o rechazados- en diferentes niveles; por ello, en esta reseña se tomó la última reimpresión del texto, en su idioma original, de manera que puedan recogerse sus elementos principales y mirarlos a la luz de las discusiones que continúan vigentes al interior de nuestra profesión.
As famílias dos homens. Os trânsitos do humanismo na fotografia internacional e brasileira
Authors: Zerwes Erika
Published: April 2018

Este artigo analisa três iniciativas fotográficas com o objetivo de discutir algumas das manifestações da fotografia humanista no pós Segunda Guerra Mundial, e suas relações com o conflito. Partindo de uma das primeiras séries fotográficas realizada por Claudia Andujar, sobre famílias brasileiras (1960-62), busca-se identificar relações possíveis com a série de reportagens People are people the world over (1948-49), e com a exposição Family of Man (1955), e assim estabelecer um diálogo entre a trajetória da fotógrafa radicada no Brasil e o movimento da fotografia humanista, especificamente em sua vertente desenvolvida nos EUA.
Fotografia e antropogênese: o melhor amigo do homem
Authors: Lissovsky Mauricio
Published: April 2018

Observando as formulações assumidas pela distinção humano/animal ao longo da história da filosofia, Giorgio Agamben (2004) concluiu que qualquer conceito de humanidade deveria tanto excluir como incluir a natureza animal. Denominou esse dispositivo metafísico de “máquina antropológica”, o processo histórico que produz separações e reconciliações entre humanidade e animalidade (tais como as relações entre corpo e alma, por exemplo). No interior dessa máquina haveria uma zona de indeterminação onde é possível perceber a tensão entre gente e bicho, onde o movimento de separação é suspenso e a própria máquina exibe sua engrenagem capenga. Seria possível flagrar esse momento? Seria possível visitar esse lugar? A premissa dessa pesquisa é que a câmera fotográfica, como máquina antropológica, tem seu papel antropogênico particularmente visível quando os seres humanos são fotografados acompanhados de cães. Valendo-se de obras como os pintores Velasquez e Rembrandt e fotógrafos como Robert Capa e William Wegman o presente ensaio visa justificar essa premissa.
Cornucópia visual mexicana: as fotografias do livro México seus recursos naturais, sua situação atual, 1922
Authors: Barbosa Carlos Alberto Sampaio
Published: April 2018

O objetivo desse artigo é perceber como o México fez uso de um discurso visual, mais precisamente fotográfico, como estratégia de propaganda diplomática, cultural e política no Brasil. Para tanto utilizarei como fonte e objeto o livro “México sus recursos naturales, susituación actual: homenaje al Brasil en ocasión del primero centenario de su independencia 1822-1922”. Essa obra, editada pela Secretaria de Indústria Comércio e Trabalho, possui 320 páginas. A construção de sua narrativa é amplamente ancorada em fotografias, o que demonstra a importância que a imagem possuía para as autoridades mexicanas. Essa publicação faz parte da participação mexicana na exposição comemorativa do Centenário da Independência do Brasil, realizada no Rio de Janeiro em 1922. O livro se insere numa ampla participação mexicana nessa exposição que contava com um pavilhão, murais, películas e outros dispositivos visuais.
Imagens encenadas? Atos performativos e construção de sujeitos nas fotografias de moda
Authors: Rainho Maria do Carmo Teixeira
Published: April 2018

A fotografia de moda, especialmente após a década de 1960, se libertou da tarefa de representar a moda como mercadoria, tornando-se experimental ou não convencional e estreitando ainda mais as suas relações com a arte. Também caracteriza a fotografia de moda, o fato de que, hoje, para além dos propósitos comerciais, possui um consentimento para discutir temas e pautas que outros tipos de imagem não apresentam. O objetivo do artigo é examinar as possibilidades do uso das fotografias de moda nas pesquisas acadêmicas e as questões que elas engendram no que tange a temas como beleza, gênero e idade.
Analyzing Historical Photographs: Genres, Functions, and Methodologies
Authors: Mraz John
Published: April 2018

***Análise de fotografias históricas: gêneros, funções e metodologias***O artigo opera com os conceitos de genero e função como contribuição no desenvolvimento de metodologias para analisar fotografias desde uma perspectiva histórica. Examina-se o gênero fotojornalismo considerando-se suas diferentes funções delimitadas por suas diversas dimensões, entre as quais: fotografia de imprensa, fotojornalismo propriamente, fotoensaios e documentarismo. Observa-se que os enganos gerados pelos praticantes desse gênero fotográfico são resultado da aplicação das regras de uma única função a todo o gênero. Assume-se a hipótese que a análise histórica pode facilitar o estabelecimento dos gêneros fotográficos e a distinção das diferentes funções dentro de um gênero.

Este artículo examina dos décadas sobre las cuales se conoce muy poco de la historia de Talamanca, una región indígena localizada en el extremo sureste de Costa Rica. Entre 1927 y 1948 la estructura interna de las comunidades indígenas talamanqueñas vivió mutaciones importantes, al igual que sucedió con la economía y la organización administrativa de la zona. Además de seguirle la pista a estos cambios, el artículo examina a cuatro individuos que fueron muy influyentes en esa época: Fermín Regidor y Neftalí Valverde, quienes fungieron como agentes de policía de Talamanca, y los hermanos Carlos Daniel y Alfredo Luis Swaby.
La alteridad interna: Las representaciones sobre el Caribe en la construcción de la identidad nacional costarricense
Authors: Anglin Fonseca Lloyd R.
Published: April 2018

El presente ensayo hace un análisis del proceso que produjo el imaginario y la articulación que realiza dicho imaginario con las representaciones fabricadas en otros contextos sobre los tópicos geográficos y racistas. Asimismo, este plantea la necesidad de vincular los procesos de construcción de representaciones sociales con las causalidades socioeconómicas que intervienen en la definición de los territorios y las comunidades imaginadas. En la construcción de la identidad nacional costarricense se han representado territorialidades que se imaginan como periféricas. Entre ellas destacan la Región Caribe del país, en la cual existen grupos étnicos y características ambientales que la separan del Valle Central, lugar que ha funcionado como el espacio donde ocurrió el nacimiento “mítico” de la nación. La metodología empleada incluye el recurso de fuentes primarias y secundarias, junto con el análisis discursivo de estas, mediante las cuales se buscó comprender la construcción del imaginario investigado. La primera parte aporta las variables de trabajo y el marco teórico en el cual se definen los conceptos de identidad y nación. En la segunda, se analiza el proceso de construcción de la sociedad costarricense en el marco de los imperialismos coloniales y en la última, se relacionan las representaciones sobre la región caribeña a partir de los condicionantes contextuales.
Fish fauna from the Langueyú basin, Argentina: a prairie stream in a heavily modified landscape
Authors: Bertora Andrea , Grosman Fabián , Sanzano Pablo , Rosso Juan J.
Published: April 2018

On the Pampa plain, one of the most productive modified areas of Argentina, important changes in land uses have drastically altered the landscape during the last decades. This has led to an increased deterioration of surface waters affecting fish that inhabit them. We provide a list of fish species inhabiting an unsurveyed prairie stream of this region. Environmental variables were measured and fish samplings were conducted in 3 sites of the Langueyú stream. A total of 15 species belonging to 10 families and 6 orders were collected. Characiformes and Siluriformes were the richest orders. Characidae was the most representative family. Species richness was highest when compared with other similar regional environments without connection with the Salado river basin. Most of the fish species collected are typical of the region but others are species which typically do not progress beyond the Salado river basin. The role of human intervention in fish species distribution is discussed.
First documented records of Lugensa brevirostris (Lesson, 1831) and Phoebetria palpebrata (Forster, 1785) for the state of São Paulo, southeastern Brazil (Aves, Procellariiformes)
Authors: Chupil Henrique , Maldaner Bruna , Marques Verônica
Published: April 2018

The order Procellariiformes comprises mainly oceanic species that are occasionally recorded from along the Brazilian coast. We presents the first records of Lugensa brevirostris (Lesson, 1831) (Kerguelen Petrel) and Phoebetria palpebrata (Forster, 1785) (Light-mantled Albatross) for the state of São Paulo, Brazil. Both species were recorded from the municipality of Ilha Comprida. Lugensa brevirostris was recorded on 25 May 2016 and P. palpebrata on 3 October 2016. Therefore, we add 2 important records to the Brazilian avifauna and suggest the inclusion of both species on the list of birds in São Paulo.
Steering interactions away from complaints about persistent symptoms in psychiatric consultations
Authors: Kushida Shuya , Yamakawa Yuriko
Published: April 2018

In medical encounters, doctors sometimes have to convey views of patients’ problems which are not in line with patients’ views and expectations. One such situation in psychiatric consultations is when the patient complains about symptoms which persist in spite of treatment, while the psychiatrist regards the patient’s condition as not serious enough to adjust treatment or has no satisfactory explanations or solutions. Based on an analysis of video-recorded psychiatric consultations in Japan, this study investigates how psychiatrists cope with such situations and shows that they steer the interaction away from the complaints using a series of moves with which they transform the reported symptoms into evidence that supports their view of the patients’ problems. It is argued that psychiatrists strike a balance between the two potentially conflicting goals of respecting patients’ epistemic authority on their symptoms and minimising inappropriate medication increases.
Solo or shared laughter in coparticipant criticism in Japanese conversation
Authors: Tanaka Hiroko
Published: April 2018

This study employs conversation analysis to examine solo production and sharing of laughter in the delivery and reception of coparticipant criticism in Japanese conversation. I argue that whilst laughter is routinely used by either the deliverer or recipient of criticism, it may be dispreferred for laughter to be shared by both parties with reference to a given criticism. Moreover, whereas solo laughter by either the deliverer or recipient of criticism tends to lead to a relatively speedy resolution of a criticism sequence, shared laughter between deliverer and recipient may signal interactional trouble and take considerable work to resolve. Such patterns suggest that even though criticising is itself a dispreferred action, shared laughter by both parties is potentially markedly dispreferred. Preliminary results of this investigation point to the possibility that interactional work performed by laughter may be more widely shared across different cultural and linguistic environments than previously assumed
Adjusting epistemic gradients
Authors: Kendrick Kobin H
Published: April 2018

In Mandarin Chinese conversation, the final particle ba contributes to the formation of a variety of social actions. Using the methods of conversation analysis, this article examines the use of the ba particle in answers to questions, informings, and assessments. It is argued that the particle serves as a turn-constructional resource for the adjustment of the epistemic gradient invoked in the sequence, downgrading the speaker’s epistemic position. In assessment sequences, the epistemic adjustment made by the particle also serves to solicit a response from the recipient who invariably has knowledge of the matter in question. An analysis of the ba particle in terms of epistemic gradients and their adjustment unifies two accounts of the particle’s function put forward in the literature.
Teologia das religiões para além do doutrinário
Authors: Gonçalves Alonso S.
Published: April 2018

ResumoA proposta que aqui se pretende, é discutir alguns critérios na abordagem das religiões em curso pela teologia. Essa relação entre teologia e religiões, se dá, principalmente, por conta do pluralismo religioso e, do necessário, diálogo inter-religioso. É sabido que o debate em torno do tema conta com diferentes enfoques e perspectivas. Esse desafio se constitui motivador, uma vez que a temática – a relação entre teologia e religiões –, está envolvida na terminologia conhecida como teologia das religiões. A nossa hipótese é de que alguns critérios para esse esforço (relação entre teologia e religiões), ainda são poucos explorados, ou evitados, como o status epistemológico de uma teologia que quer pensar o fenômeno religioso antes do enquadramento doutrinário de uma determinada experiência religiosa.Palavras-chave: Teologia das Religiões.

Amós 7.1-6: Amós não pede por justiça, mas por misericórdia
Authors: Jacinto José Ribamar Mendes Filho
Published: April 2018

Este trabalho se propõe a estudar a passagem de Amós 7.1-6, buscando entender o que está implicado teologicamente no primeiro par de visões, respondendo o que levou Deus a se arrepender. O trabalho está dividido em três seções: a primeira seção busca analisar a visão dos gafanhotos e do fogo, considerando que elas apontam para um juízo de Deus sobre um povo fraco e pequeno. Das informações obtidas nesta primeira parte, buscar-se-á interligá-las à segunda parte (apelo em favor de um povo fraco e pequeno), focalizando a ideia de um apelo em favor do povo de Israel, buscando entender as primeiras implicações teológicas a respeito do juízo de Deus como “o dia de Javé”. Este dia de Javé, tanto positivo quanto negativo para o povo de Deus, só poderá ser impedido se houver uma intercessão em favor do povo.
A revelação por excelência no paradoxo da presença de Deus na história: um possível diálogo entre Rudolf Bultmann e Karl Rahner
Authors: Veliq Fabrício
Published: April 2018

Nesse artigo, propomos trabalhar as concepções antropológicas de Karl Rahner, a partir da obra de Gustavo Baena, e Rudolf Bultmann, mostrando suas possíveis convergências e divergências. Como ponto divergente, enquanto, em Bultmann, temos uma visão pessimista do ser humano, podemos perceber em Karl Rahner uma visão mais otimista do mesmo. Como ponto convergente, as duas antropologias culminam na figura de Jesus enquanto revelação por excelência através de uma presença de Deus na história.
Breve História da Arqueologia Bíblica: Contribuição e Crítica Estadunidense
Authors: Darius Fábio Augusto , Hosokawa Elder
Published: April 2018

A arqueologia bíblica, ramo da arqueologia que se dispõe a estudar as evidências materiais relacionadas de forma direta ou indireta a partir de relatos bíblicos ou evidenciados ao texto das Escrituras judaico-cristãs tem sua origem com o nascimento da própria arqueologia. Suas técnicas, inclusive, são as mesmas. Seu escopo não é o de objetivamente comprovar a fé ou desvelar supostos erros cometidos pelos autores dos textos bíblicos, mas tão somente instrumentalizar o estudante da Bíblia e/ou da arqueologia em geral para que melhor se compreenda e visualize os textos históricos. O objetivo do presente trabalho é, de forma incipiente, relacionar os principais nomes e acontecimentos deste ramo arqueologia desde suas origens, ainda no século XIX até o presente, a partir da história da arqueologia tradicional e apresentar a contribuição estadunidense para pesquisa e divulgação e crítica à arqueologia bíblica.
FORMAÇÃO TÉCNICA E EMPREGABILIDADE EM PROGRAMAS SOCIAIS: A EXPERIÊNCIA DO PROGRAMA BOLSA FAMÍLIA E DO PRONATEC EM UMA CIDADE DA FRONTEIRA BRASIL-URUGUAI
Authors: Camara Guilherme Dornelas
Published: April 2018

Resumo: O objetivo deste trabalho é analisar a repercussão do Programa Nacional de Acesso ao Ensino Técnico e ao Emprego (PRONATEC) para a inserção e qualificação profissional. Nos debates acadêmicos, técnicos e do senso comum sobre a sua efetividade para o fim da pobreza, muitas vezes se questiona sua influência sobre a estabilidade do trabalhador no mercado de trabalho. Contudo, poucos estudos têm se dedicado a verificar junto aos próprios beneficiários a relevância do PRONATEC para a inserção profissional, caminho considerado sustentável para o combate à situação de vulnerabilidade das famílias beneficiárias. Propondo-se a essa análise, o trabalho parte de dados coletados em entrevistas com beneficiários do PRONATEC e do PBF (Programa Bolsa Família) em uma cidade da fronteira do Brasil com o Uruguai. É abordada a importância econômica dos programas sociais para as famílias frente às dificuldades do mercado de trabalho local.

Published: April 2018

ABSTRACT Chronic renal patients are more susceptible to hospital complications and infections such as urinary tract infections, peritonitis, surgery infections, and bacteremia, which are often caused by Pseudomonas aeruginosa. A case of a HIV-positive girl with chronic kidney disease and with serious oral lesions due to P. aeruginosa septic shock is presented. The patient showed necrotic lesions in the oral mucosa, pathological tooth mobility, bone loss, and hematogenous osteomyelitis in the maxilla. The patient was submitted to systemic antibiotic therapy based on screening culture and treatment of bone lesions by eliminating the causal agent and restoring health conditions. This case report is extremely important for health professionals, since the oral cavity can be affected by this pathogen or serve as a colonization site.

ABSTRACT Introduction: Ischemia-reperfusion (IR) injury results from inflammation and oxidative stress, among other factors. Because of its anti-inflammatory and antioxidant properties, the Brazil nut (BN) might attenuate IR renal injury. Objective: The aim of the present study was to investigate whether the intake of BN prevents or reduces IR kidney injury and inflammation, improving renal function and decreasing oxidative stress. Methods: Male Wistar rats were distributed into six groups (N=6/group): SHAM (control), SHAM treated with 75 or 150 mg of BN, IR, and IR treated with 75 or 150 mg of BN. The IR procedure consisted of right nephrectomy and occlusion of the left renal artery with a non-traumatic vascular clamp for 30 min. BN was given daily and individually for 7 days before surgery (SHAM or IR) and maintained until animal sacrifice (48h after surgery). We evaluated the following parameters: plasma creatinine, urea, and phosphorus; proteinuria, urinary output, and creatinine clearance; plasmatic TBARS and TEAC; kidney expression of iNOS and nitrotyrosine, and macrophage influx. Results: Pre-treatment with 75 mg of BN attenuated IR-induced renal changes, with elevation of creatinine clearance and urinary output, reducing proteinuria, urea, and plasmatic phosphorus as well as reducing kidney expression of iNOS, nitrotyrosine, and macrophage influx. Conclusion: Low intake of BN prior to IR-induced kidney injury improves renal function by inhibition of macrophage infiltration and oxidative stress.

ABSTRACT This study aimed to analyze Brazilian exports of softwood moldings between the years 1997-2013, by means of a gravity trade model. The main explanatory variables used were GDP of Brazil, importing country´s GDP, and distance between Brazil and its trade partner. The results showed that all variables had the expected behavior. The variables´ coefficient of GDP of Brazil and the importing country's GDP presented a positive influence on trade flow of softwood moldings. The distance coefficient presented a negative influence on trade flow, which showed to be a barrier to Brazilian exports of this product. Results also show that the level of trade is more influenced by the GDP in Brazil than at the importing country's GDP.
Flexural behaviour of RC beams strengthened with combinations of two CFRP systems and P-SWRs
Authors: Li Xinghua , Wu Gang , Bian Renyuan
Published: April 2018

Externally bonded (EB) carbon fibre-reinforced polymer (CFRP) sheets, near-surface-mounted (NSM) CFRP bars and prestressed steel wire ropes (P-SWRs) are widely used for strengthening reinforced-concrete (RC) beams. Existing research has shown that it can be inefficient or infeasible to provide sufficient load-carrying capacity using one strengthening method because of the CFRP strain limitation at debonding or the upper bound on the amount of strengthening materials due to limited space for strengthening. Moreover, some already strengthened RC beams need to be further strengthened under heavier loading conditions. Therefore, using a combined strengthening scheme for one beam should be considered in both these situations. In this study, five concrete beams were strengthened and tested to explore the effects of different combined schemes on beam flexural behaviour. The results demonstrate that P-SWRs are of crucial importance in improving the cracking behaviour and ductility of beams originally strengthened with EB-CFRP sheets or NSM-CFRP bars. The strengthening scheme of NSM-CFRP bars and P-SWRs is found to be better than that of EB-CFRP sheets and P-SWRs. A recommendation for the appropriate selection of strengthening schemes is given based on the test results.

Physical modelling under the gravitational field between 0 and ng plays a key role in both terrestrial- and aerospace-geotechnical engineering. A geotechnical magnetic–similitude–gravity model testing (GMMT) method is newly proposed to provide an alternative approach to the current physical modelling methods. The theoretical criteria for achieving a magnetic field to simulate the gravitational field are presented first, based on which an exact simulation of the stress field is achieved between the physical model and its corresponding prototype. A GMMT equipment is then designed and manufactured, and a related procedure for obtaining its control and input parameters is presented. Accordingly, the preparation of the model material is demonstrated utilising a kind of magnetically sensitive granular (MSG) media. The relationship between mechanical properties, magnetisation, magnetic–similitude–gravity and magnetic powder content of the MSG media are further investigated, and the influences of both magnetising field and magnetisation process are shown to be negligible in terms of mechanical behaviour. A series of physical modelling of the bearing capacity of granular media under low-gravity conditions is finally performed using the GMMT equipment. The results show good agreement with previous data obtained by the parabolic flight aircraft.
