Dinámica de fragmentación en la Sierra Madre Oriental y su impacto sobre la distribución potencial de la avifauna
Authors: Castro-Navarro Jaime , Sahagún Sánchez Francisco Javier , Reyes-Hernández Humberto
Published: September 2017

La fragmentación y los cambios en el uso de suelo constituyen factores clave a nivel global para la pérdida de la biodiversidad. En este estudio, se analizó la dinámica de fragmentación en las coberturas vegetales y usos de suelo en la región de la Sierra Madre Oriental del estado de San Luis Potosí, México, para evaluar su impacto sobre las áreas de distribución potencial de la avifauna y las regiones prioritarias para la conservación. Se realizó trabajo de campo y se colectó información sobre la distribución de las aves, a partir de la cual se elaboraron modelos de distribución potencial de especies con el programa MaxEnt. La información fue comparada con los datos del análisis de fragmentación obtenidos, a partir de lo cual se determinó que, las coberturas de vegetación natural son proclives a la fragmentación, mientras que las coberturas asociadas a las actividades humanas tienden a conectarse e incrementar su superficie. La zona centro y suroeste de la región tiene la mayor tendencia a la fragmentación de la cobertura vegetal, dando lugar a una alta heterogeneidad en el paisaje. Lo anterior afecta las áreas de distribución de 34% de las especies modeladas debido a la pérdida de conectividad entre hábitats y al aumento del efecto de borde. Los resultados confirman la importancia de la región como un centro de alta diversidad avifaunística y evidencia la necesidad de establecer acciones de conservación a corto plazo para mantener las áreas de distribución de importancia para las aves en la zona.

Authors: Aguilar-Caro Aura
Published: September 2017

En adelante, se sintetizan las principales conclusiones del desarrollo de un proyecto de investigación que se origina desde el aula, en la asignatura Metodología de la Investigación Científica a estudiantes de Psicología en la Universidad Simón Bolívar en la ciudad de Barranquilla-Colombia. Se parte de la psicología social, a través de las representaciones sociales, para realizar el trabajo de campo, cuyo objeto de investigación es un proyecto de arte urbano (imágenes en paredes) en Barranquilla-Colombia, mediante observaciones directas, revisiones ocumentales y entrevistas. Se analizan las imágenes que emergen en cada uno de los murales del proyecto de Arte Urbano Killart 2017; y se define la categoría de las representaciones femeninas, masculinas y naturaleza. En ese contraste, el objetivo central fue que los/las estudiantes se acercaran a la realidad y ocupando técnicas de investigación, pudieran interpretarla, considerando que Barranquilla es una de las ciudades que tiene el desafío de comprensión de lo femenino, que en el caso de la violencia hacia la mujer, viene ocupando los primeros lugares del país en cuanto a feminicidios se refiere. Se ha derivado de este trabajo en conjunto con la participación de los/las estudiantes un documental, en el que se pone de relieve el tema de lo femenino y la importancia de la mujer, se resalta su valor humano y el capital cultural que la define en el aporte de la construcciones familiares y sociales en nuestro entorno caribe.
Le doublage, à la frontière entre traduction et adaptation ?
Authors: Brisset Frédérique
Published: September 2017

La traduction audiovisuelle, si elle est se prête à la glose métaphorique du passage de frontière linguistique comme toute autre forme de traduction, remet pourtant en question le concept de frontière : de l’écrit au parlé, de l’oral spontané à l’oral de performance, de l'entendu au vu, la ligne est imprécise. La frontière est donc plus vecteur de passage dans un continuum que de fermeture, malgré ce processus très contraint qu'est le doublage, dont nous nous attachons ici à définir les modalités, en approfondissant les concepts de traduction et d’adaptation : la littérature scientifique montre qu’ils se refusent à toute délimitation normative et sont l'objet d'un constat débat.

Notre intérêt se porte notamment sur la place de l’adaptateur-dialoguiste comme passeur linguistique et culturel du "texte" filmique, et sur l’importance de l’interprétation et de la phase de réception dans les choix traductifs induits, en particulier pour le doublage interlinguistique. L’image que se fait le traducteur du spectateur final devient alors déterminante pour subvertir avec succès la dichotomie auteur/cinéaste originel-spectateur allophone final. Nous nous appuyons pour cette étude sur la notion d’herméneutique comme exégèse et sur la théorie de la réception de Jauss et les notions afférentes d’Auteur et Spectateur modèles.

Published: September 2017

A sexualidade de idosas com incontinência urinária tem se constituído um problema de pesquisas por ser afetada pelo surgimento de problemas de ordem psicoemocional que limitam as suas atividades diárias e interação social, diminuindo a qualidade de vida dessas pessoas. O objetivo da pesquisa foi investigar a produção científica nacional on-line acerca da sexualidade de idosas com incontinência urinária. Para tanto, fez-se uma revisão integrativa da literatura no site da Biblioteca Virtual de Saúde, mediante os descritores: “sexualidade”, “incontinência urinária” e “idosas”. Os artigos selecionados corresponderam ao período de 2007 a 2013 e a coleta de dados ocorreu em setembro e outubro de 2014. Os trabalhos que se enquadraram dentro dos critérios de elegibilidade foram lidos na íntegra e os dados foram analisados qualitativamente por meio da técnica de análise categorial temática. A amostra foi composta por 13 artigos. De posse dos dados, percebeu-se que foram elencadas duas categorias temáticas: as repercussões da incontinência urinária na sexualidade das idosas e as limitações na qualidade de vida de idosas incontinentes. Concluiu-se que os resultados empíricos obtidos por meio deste estudo representam subsídios importantes para o planejamento e para a implementação de intervenções, a fim de melhorar as condições de vida e o bem-estar da sexualidade das idosas incontinentes.

ATELIER GAIA: SUA HISTÓRIA E A ARTE NO CAMPO DA ATENÇÃO PSICOSSOCIAL
Authors: Fabrício Paula Conceição , Amendoeira Maria Cristina Reis , Cavalcanti Maria Tavares
Published: September 2017

O Atelier Gaia é um serviço criado na Colônia Juliano Moreira, zona oeste do Rio de Janeiro, com origem no Museu Nise da Silveira, atual Museu Bispo do Rosário Arte Contemporânea (MBRAC), na década de 80 do século XX, nos anos iniciais da Reforma Psiquiátrica Brasileira, período de transição do modelo asilar para a atenção psicossocial. O objetivo deste artigo é registrar a história e evolução do espaço, contrapondo com as ideias de Nise da Silveira, corroborando o entendimento e a constatação de como o uso terapêutico da produção artística é capaz de promover a reabilitação psicossocial dos envolvidos na criação. A metodologia adotada foi a pesquisa qualitativa, na qual se utilizou as técnicas observação participante, estudo de caso e entrevistas aprofundadas, individuais e em grupo com os personagens do atelier, o que permitiu observar a importância que teve na subjetivação, autonomia e liberdade destes indivíduos. Concluiu-se que a continuidade do Atelier Gaia e a expansão de serviços similares por toda rede de cuidado deveria ser garantida como espaço terapêutico e de criação, o que poderia representar uma nova fase de desenvolvimento no modelo assistencial, isto é, uma reforma cultural por meio da própria cultura e da arte. Foi desta maneira que o Atelier Gaia estruturou-se e participou da reabilitação psicossocial de todos os que estiveram envolvidos com o seu desenvolvimento, proporcionando subjetivação, autonomia e reduzindo a necessidade do aparato manicomial e assim fortalecendo o campo da atenção psicossocial.

Published: September 2017

A sífilis congênita é uma doença de fácil diagnóstico e que pode ser prevenida, desde que seja realizado o tratamento adequado da gestante e de seu parceiro, mas ainda é considerada um problema de saúde pública. O objetivo deste estudo foi avaliar a situação epidemiológica da sífilis congênita no município de Fortaleza no ano de 2012 por meio da análise do comportamento da doença nos últimos 11 anos e da influência das Secretarias Executivas Regionais na notificação. Para tanto, realizou-se um estudo do tipo epidemiológico, observacional, documental e descritivo no Sistema de Informação de Agravos de Notificação e Departamento de Informática do Sistema Único de Saúde. Os resultados encontrados apontaram que, em 2012, foram notificados 566 casos de sífilis congênita, 360 (63,6%) das mulheres tinham de 20 a 34 anos, 488 (86,2%) raça parda, 333 (58,8%) Ensino Fundamental incompleto, 357 (63,1%) realizaram pré-natal, porém apenas 197 (55,1%) foram diagnosticadas e 10 (1,7%) receberam o tratamento adequado. Em 2012, a taxa de incidência foi de 15,2/1000 nascidos vivos. Entre 2002 a 2012, foi verificada uma tendência anual crescente p (<0,0001), passando de 1,0 a 15,2. Assim, concluiu-se que Fortaleza apresenta uma alta taxa de notificação da doença, o que aponta a necessidade de ações mais efetivas no seu controle.

ATUAÇÃO DA ENFERMEIRA NA SALA DE VACINAÇÃO EM UNIDADES DE SAÚDE DA FAMÍLIA
Authors: Argolo Cerqueira Isis Thamara , Santa Barbara Josele
Published: September 2017

A atuação da enfermeira na sala de vacinação é de suma importância na assistência e nas ações que são desenvolvidas nesse ambiente, visto que esse profissional deve atuar em todo o processo de imunização, levando sempre em consideração a orientação e educação em saúde dos usuários desse serviço de saúde, bem como o treinamento e a capacitação da equipe de saúde, buscando uma assistência humanizada. O objetivo deste trabalho foi conhecer a atuação da enfermeira na sala de vacinação em Unidades de Saúde da Família de um município do recôncavo baiano. Para tanto, foi utilizada a abordagem qualitativa, tendo como instrumento de coleta de dados a entrevista semiestruturada relacionada à temática. Os sujeitos da pesquisa foram as enfermeiras pertencentes às Equipes de Saúde da Família dos Distritos Sanitários II e III. A análise de dados foi realizada por meio da ordenação, classificação e análise propriamente dita dos dados. Os resultados indicaram que, com relação à atuação da enfermeira nos seus aspectos gerenciais e assistenciais na sala de vacinação, as entrevistadas relataram que atuaram na supervisão, no manuseio dos impressos específicos da vacinação e na triagem neonatal. Concluiu-se que a atuação da enfermeira na sala de vacinação foi pouca ou ausente, ficando a técnica de enfermagem, na maioria das vezes, como responsável por este setor, que, em sua formação, não teve disciplinas que a capacitassem para gerenciar e ser responsável técnica pela sala de vacinação.

Authors: Mitrovic Aleksandra , Tanasic Ivan , Mitrovic Nenad , Milosevic Milos , Tihacek-Sojic Ljiljana , Antonovic Dusan
Published: September 2017

Introduction/Objective. In an attempt to simplify dental procedures, a new group of resin cements, self-adhesive resin cements (SARCs), have been introduced. Performance of SARCs can widely vary. One of the main reasons of adhesion failure is polymerization shrinkage. The aim of this study was to determine, evaluate, and measure strain field of self-adhesive dual cure resin cement during polymerization in self-cure mode using 3D digital image correlation (DIC) method. Methods. The self-adhesive Maxcem Elite (Kerr, Orange, CA, USA) cement was tested in five cylindrical samples (5 mm in diameter and 2 mm in thickness) prepared by filling plastic ring-type molds. Digital images were recorded immediately after sample preparation. Results. Non-uniform strain distribution was found in resin cement with higher strain values along the periphery (up to 15%) and lower strain values in central parts (around 4%) of each sample. Conclusion. It can be concluded that DIC is a powerful tool for full-field strain measurements in material characterization.

Introduction/Objective. Dry eye development after phacoemulsification is a very common complication of cataract surgery. Combined with other risk factors, such as pseudoexfoliation (PEX), this complication becomes more frequent. The aim of this study was to expose the influence of phacoemulsification associated with PEX on the development of dry eye in patients who underwent cataract surgery. Methods. The study included 160 eyes (160 patients) who underwent phacoemulsification. The patients were divided into four groups (n = 40 patients). Groups I and II involved patients without PEX. The patients from Group II were prescribed artificial tears (AT) postoperatively. The patients from Groups III and IV had a presentation of PEX. The patients from Group IV got AT postoperatively. Ocular Surface Disease Index, the tear breakup time (TBUT) test, fluorescein staining, and Schirmer?s test served as ?dry eye? tests in this study. The ?2 test and paired t-test were used for data analysis. Results. Measurements were taken for every patient preoperatively, on the first and the seventh day after the surgery, one month and three months, and one year after the surgery. The tests showed postoperatively developed dry eye in all the groups, with the recovery of the tear film within three months, except for Group III. The highest statistical significance (p < 0.001) was recorded between Groups II and III, three and 12 months after the surgery. Values of TBUT (6.09 ? 1.29 seconds) and Schirmer?s test (8.91 ? 2.14 mm) in Group III strongly indicated that dry eye was still present one year after phacoemulsification. The greatest recovery of the tear film was recorded in Group II in all the measurements. Conclusion. The study showed how strongly PEX and the use of AT affect the tear film during the first postoperative year. Based on our experience, we highly recommend the use of AT after performing phacoemulsification.

Published: September 2017

Background/Aim. The main task of endodontic treatment is to eliminate pathologically altered tissue, to disinfect root canal space and to obtain its three-dimensional hermetic obturation. The main purpose of this study was to evaluate antimicrobial activity of new endodontic nano-structured highly active calcium silicates based materials albo-mineral plyoxide carbonate aggregate (ALBO-MPCA) and calcium silicates (CS) in comparison to mineral trioxide aggregate (MTA+) and UltraCal XS (CH). Methods. The antimicrobial activity of materials was tested against Staphylococcus aureus (ATCC 25923) and Enterococcus faecalis (ATCC 14506) strains, and following clinical isolates: Rothia dentocariosa, Enterococcus faecalis, Staphylococcus aureus, Streptococcus anginosus and Streptococcus vestibularis using a double layer agar diffusion test. The pH measurements were performed using the pH meter. Total amount of released ions was determined by inductively coupled plasma optical emission spectrometry (ICP-OES). Results. All tested materials showed the best antibacterial potential after 1 h of incubation. After 3h and 24h of the incubation period, the antibacterial potential of all tested materials were similar. The Agar diffusion test showed that ALBO-MPCA, CS and MTA+ had similar inhibition zones (p > 0.05), except in the activity against Staphylococcus aureus where ALBO-MPCA showed better antimicrobial properties than MTA+ in 3h and 24h of the incubation period (p < 0.05). Following 24h of the incubation, the inhibition zones were the strongest with CH against Staphylococcus aureus (16.67 ? 2.34 mm) followed by ALBO-MPCA (14.67 ? 1.21 mm) and the weakest with CS against Enterococcus faecalis (6.50 ? 1.76 mm). CH showed the highest pH, followed by ALBO-MPCA, CS and MTA+. Conclusion. The expressed antibacterial effects indicate that materials based on nano-structured highly active calcium silicates represent effective therapeutic agents for root canal obturation in one-visit apexification treatment, therefore they are recommend for further examination and clinical trials as they are proposed for MTA substitution.

Introduction: Mitral valve calcifications are frequent finding in the Barlow
disease. This is makinkg mitral repair surgery even more demanding in already
complex valve pathology. Case report: Fifty-five year old Barlow disease
patient underwent mitral repair surgery due to posterior leaflet prolapse at
P2 level and extensive posterior leaflet and annular calcifications as well.
Prolapsed scalop was resected, while P1 and P3 scalops were detached from the
annulus. After complete posterior annulus decalcification, so formedlarge
atrio-ventricular defect was reconstructed with autologous pericardial patch
and double suture line technique.P1 and P3 segments were reatched thereafter
by sliding technique, and sutured with no strain. Annuloplasty was performed
with saddle rigid ring No 36. Patient was discharged nine days after the
surgery with just a trace of mitral reguritation. Conclusion: Annular
decalcificaion and reconstruction in patients with calcified Barlow mitral
disease is neccessary for safe and durable mitral valve repair surgery.

Authors: Medeiros Maria Jucicléa dos Santos , Sousa Rafaela Lopes de , Oliveira Douglas Moreira de , Silva Ana Paula Alves da , Lima André Luiz Alves de
Published: September 2017

Em ambientes semiáridos as plantas estão sujeitas a condições estressantes devido altas temperaturas, intensidade luminosa e longa estiagem, que são limitantes para estabelecimento das plântulas. Uma forma de minimizar os estresses é inoculando rizobactérias promotoras do crescimento de plantas (RPCP). Objetivou-se avaliar, em diferentes condições de luminosidade, a eficácia da inoculação de uma RPCP no desenvolvimento de plântulas de Myracrodruon urundeuva Allemão. Foram aplicados 4 tratamentos: Pleno sol com inóculo; Pleno sol sem inóculo; 70% sombreamento com inóculo e 70% sombreamento sem inóculo.  Realizou-se coletas de dados quinzenalmente de altura, diâmetro, número de folhas e temperatura foliar (Tf). O déficit de pressão de vapor foi determinado através da temperatura e umidade do ar. Foram avaliadas parâmetros de potencial hídrico foliar, biomassa, área foliar, área foliar específica e área radicular. As plântulas apresentaram maior crescimento sob sombreamento, demonstrando mecanismo de desenvolver-se melhor em baixa luminosidade, e a inoculação da bactéria proporcionou aumento em altura e diâmetro das plântulas, além de maior Tf na maioria dos dias. As plântulas dos tratamentos ao sol investiram mais em biomassa radicular, enquanto que no sombreamento investiram mais na parte aérea. O potencial hídrico não variou entre os tratamentos, indicando que ajustaram-se às condições submetidas. Conclui-se que o uso RPCP é bastante promissor, especialmente, para implantação de espécies vegetais na recuperação de áreas degradadas, bem como a condição de maior sombreamento favorece o estádio inicial de desenvolvimento das plântulas.

Authors: Sharma Bharat Bhushan , Bhardwaj Naveen , Dewan Sakshi , Sharma Sandeep , Ramachandran Priya , Kakria Hira Lal , Aziz Mir Rizwan
Published: September 2017

Background:

Medial tibial stress syndrome (MTSS) or shin splints is the result of soft tissue injuries surrounding the tibial shaft. The most common causative factor is that of repetitive trauma while doing exertional exercises and maneuvers. These injuries cause pain in the lower leg and affects the lower part of the tibia shaft. This is frequently encountered in athletes and dancers.

Case Presentation:

We present a 22 year old college student who happened to be in the athletic team and reported with the left leg pain. Various radiological investigations diagnosed him as a case of medial tibial stress syndrome (MTSS). Magnetic resonance imaging played a pivot role in grading the injury and patient was advised accordingly.

Conclusion:

MTSS may remain unnoticed till the time it causes concern of non resolving pain of the lower leg. The case requires careful evaluation for the management purpose. Fredericson MRI classification helps in deciding about the conservative or surgical management.

Background:

Lipomas are most frequent benign soft tissue tumours with incidence of about 6%. For giant lipoma, chest wall is the rare site. Extension in the thoracic cavity is unique. No case of chest wall lipoma with extension in thoracic cavity is reported.

Case presentation:

We report a rare case of left anterior chest wall lipoma in 45 year old man for 15 years. It had extension in the thoracic cavity. On CT scan, its size was 145mm × 132mm × 90mm and in the chest cavity it was 119mm × 60mm × 72mm size. Patient had minimum symptoms. Core biopsy confirmed the benign nature. Surgical excision under GA was done. Recovery was uneventful. Histopathology report confirmed as “Giant Lipoma”.

Conclusion:

Giant lipoma of the anterior chest with extension into thoracic cavity is a rare presentation. Even with such large size, they can give minimum symptoms. Proper pre-operative assessment of such large lesions is very important for proper management.
Effects of the Internet on young people: A view from neuroscience
Authors: Pham Linh
Published: September 2017

It is unimaginable this world without the Internet given its ubiquity, power, and breadth of influence. However, Internet addiction is a real source of worry, and even comparable to substance-related addictive disorders. Changes in brain chemistry and structure resulted from the Internet use and overuse are of particular concern to researchers and educators, because of their profound effects on young people’s development. This paper discusses these impacts by looking at three specific aspects including Internet searching, gaming, and social networking. By drawing particularly on neuroscientific evidence, the paper comes to the conclusion that the Internet proves to be a valuable tool for young people provided that it is used sensibly in close connection with teachers’ guidance.

Authors: El-Alfy Muhammad Abdul-Hady , El-Azim Hoda Abd , El-Amier Yasser A.
Published: September 2017

Burullus Lagoon is one of the five Mediterranean Lagoons of Egypt which used for many purposes including fishing, recreation and contains many organisms. This investigation was aimed to assess the variation pattern in trace metals contamination in different sectors of Burullus Lagoon. Number of 34 representative water samples were collected and analyzed for 7 trace elements according to the standard method. Spatial distribution maps for these metals were created using ordinary Kriging method in ArcGIS. The obtained results indicated that the dissolved heavy metals in Burullus Lagoon were in the range of; Fe (10.55-48.6 µg/l), Pb (2.62-10.76 µg/l), Cu (0.80-48.21 µg/l), Zn (1.65-29.9 µg/l), Co (2.26-7.74 µg/l), Cr (nd-0.82 µg/l) and Cd (nd-9.91 µg/l). The Lagoon is receiving huge amounts of drainage water at the southern parts in comparison to the northern parts. It was also showed that, the highest mean concentrations of most dissolved trace metals take the following sequence: Western > Middle > Eastern. It is highly recommended to control the destructive human activities around the lagoon and to treat resultant wastewater before discharge into the lagoon.
Redes políticas y distribución de recursos públicos a nivel subnacional: Las relaciones provincia-municipios en el caso Córdoba, Argentina
Authors: Mazzalay Víctor , Nazareno Marcelo , Cingolani Mónica
Published: September 2017

En los contextos post-descentralización, las relaciones intergubernamentales (RIGs) central-locales adquieren gran relevancia para comprender los procesos de asignación territorial de recursos públicos. La elevada autonomía local en la Provincia de Córdoba, Argentina, hace de ésta un caso apropiado para examinar la complejidad de factores involucrados en la distribución de recursos a municipios y, de este modo, generar aproximaciones heurísticas sobre estos procesos a nivel regional. Este estudio (a) da cuenta de la coexistencia de dos subsistemas de RIGs, a través de los cuales los gobiernos locales procuran acceder a recursos públicos de decisión discrecional, uno conformado por redes políticas formales y otro por una diversidad de redes políticas informales; (b) se observa un efecto sistemático de ambos tipos de redes sobre las chances de acceso de los gobiernos locales a recursos de decisión discrecional del gobierno provincial; (c) se advierte que los gobiernos locales adoptan una estrategia combinada de vinculación a ambos tipos de redes, priorizando el mecanismo de la cohesión en las redes formales y la intermediación en las redes informales.
Latin American Critical Epistemologies toward a Biocentric Turn in Communication for Social Change: Communication from a Good Living Perspective
Authors: Barranquero Carretero Alejandro , Sáez Baeza Chiara
Published: September 2017

This article reviews the historical and theoretical foundations of communication for development and, in particular, communication for social change, a recently coined concept that remains anchored to an anthropocentric and unsustainable perspective of development. Based on the review of literature, we would like to open a dialogue between the field and Latin American contemporary debates, with a special focus on a number of theoretical frameworks that share a radical critique of modernity and stand for a biocentric turn in social sciences: the so-called modernity/coloniality research program, critical ecology, and indigenous epistemologies. We propose approaching communication theories from the indigenous worldview of “good living” (buen vivir) and quote several inspiring participatory projects that apply the new epistemologies to the field.
Manejo de recursos forestales no maderables y las políticas de simplificación: El caso de la palma xate en la Selva Lacandona, México
Authors: Buda Arango Gabriela , Durand Leticia , Trench Tim , Figueroa Fernanda
Published: September 2017

El uso de Recursos Forestales No Maderables (RFNM) puede crear oportunidades de desarrollo para poblaciones locales; pero ello requiere de determinadas condiciones. En México, el uso de RFNM considerados oficialmente como “amenazados” es regulado por Unidades de Manejo para la Conservación de la Vida Silvestre (UMA), un instrumento que busca conciliar la conservación biológica con desarrollo local. Sus resultados varían en función de las características del contexto en que se aplica. La mayoría de las UMA del sur del país, especialmente de RFNM, muestran resultados poco alentadores, pues no consideran en su diseño e implementación, la complejidad y diversidad de condiciones presentes en los espacios rurales de esta región. Aquí analizamos la implementación de una UMA de palma camedor en dos comunidades rurales de la Selva Lacandona, Chiapas, México, a través de registro etnográfico, entrevistas a profundidad y cuestionarios socioeconómicos. Argumentamos que las UMA de palma parten de una concepción simplificada de la realidad compleja de las comunidades en donde se implementan y trastocan su equilibrio de poder; su diseño burocrático y sobre-regulatorio fomenta discrecionalidad, simulación y corrupción, lo que acentúa la exclusión y favorece a las élites locales.
Implanted chemical sensors for functional radiography
Authors: Arifuzzaman Md , Millhouse Paul W. , Raval Yash , Pace Thomas B. , Behrend Caleb J. , DesJardins John D. , Tzeng Tzuen-Rong J. , Anker Jeffrey N.
Published: September 2017

A biomedical sensor is designed to noninvasively measure local pH changes on the surface of implanted devices for detecting and monitoring implant-associated infection using plain radiography. The sensor comprises a radiopaque pin embedded within a polyacrylic acid-based hydrogel. pH-modulated hydrogel expansion and contraction is determined by radiographically measuring the pin position. The sensor was calibrated in a series of standard pH buffers, and tested in a bacterial growth culture. The sensor calibration was insensitive to changes in temperature and ionic strength within the normal physiological range. The response time depended on sensor thickness, and was approximately 30 min for 1 mm thick films. Radiographic measurements were also performed through tissue and bone with the sensor attached to an orthopedic plate fixated to a human cadaver tibia. Plain radiographs were selected for readout since X-rays are routinely used in inpatient and outpatient settings for structural or anatomical information. The chemically-responsive hydrogel sensors can provide additional functional information in a clinical setting by indicating local chemical concentrations near the implant surface using routinely obtained radiographs.
Can mindful doctors take better care of their patients? How mindfulness can benefit medical care beyond serving as a clinical intervention for patients
Authors: Falkenberg Ruth Ingeborg
Published: September 2017

The potential of mindfulness as a clinical intervention is increasinglyrecognized, yet less attention has been paid to how mindfulnesscan contribute to medical care when cultivated by physicians.This paper examines how mindfulness in practitioners can alleviatethree problems arising in contemporary medical care. Firstly,mindfulness could prevent flaws resulting from mindless medicalpractice by allowing practitioners to become more aware of theirpatients and their own cognitions. Secondly, mindfulness can alleviatethe problem of chronic stress and burnout in medical practitioners,thereby enhancing their care of patients. Finally, mindfulnesscan contribute to improving patient-practitioner-relationshipswhich often suffer in contemporary healthcare. In sum, mindfulnessin practitioners holds great potential for medical care; hence mindfulness-programs for physicians should be implemented.

Debates within critical educational theory and its relation to capitalism have often been heavily influenced by the tradition of critical social theory. For instance, Jurgen Habermas’ communicative action approach has proven to be a valuable theory that combines both analytical considerations regarding the conflict between the ‘lifeworld’ and ‘system’, and a decisively normative theory for deliberative and democratic discourse. However, Habermas’ communicative action does not go without problems, as a critical linguistic approach may prove. As such, in this paper I attempt to analyse the issues of communicative action in the context of anti-capitalist discourse and debate within and about higher education. To do this, I first outline Habermas’ and Fleming’s theories on the colonization of higher education, followed by a critique by means of Wittgenstein’s philosophy of language. As such, I attempt to argue that, in order to decolonize higher education from the ‘logic of capital’, we must reflect upon the language-games used when speaking about education.
Experiential Metaphors in Abstract Games
Authors: Begy Jason
Published: September 2017

Despite their age and prevalence, abstract games are often overlooked in contemporary discussions of games and meaning. In this paper I offer experiential metaphors as a critical method applicable to all games, particularly abstract games. To do this I introduce structural metaphors, image schemata and experiential gestalts to explain how experiential metaphors function. I then compare this method with the simulation gap (Bogost 2006, 2007) and show how the two relate. I close with two examples of abstract games that function as experiential metaphors.
Breaking Reality: Exploring Pervasive Cheating in Foursquare
Authors: Glas René
Published: September 2017

This article explores the notion of cheating in location-based mobile applications. Using the popular smartphone app Foursquare as main case study, it addresses the question if and how devious practices impact the boundaries between play and reality as a negotiated space of interaction. After establishing Foursquare as a prime example of the gamification phenomenon and pervasive gaming, both of which require us to rethink notions of game and play, it is argued that cheating in location-based mobile applications like Foursquare has the potential to challenge not just the boundaries of play, but also our playful identity.
Beyond the digital divide: An ecological approach to gameplay
Authors: Linderoth Jonas
Published: September 2017

This paper outlines a framework for understanding gameplay from the perspective of ecological psychology. According to this perspective, gameplay can be described in terms of perceiving, acting on and transforming the affordances that are related to a game system or to other players in a game. Challenges in games have an emphasis on perceiving suitable actions and/or performing suitable actions, often with emphasis on one aspect. For example, in many board games, strategy games and puzzle games, the challenge is to perceive appropriate affordances while in many sports, multiplayer shooter games, racing games, etc. the challenge is to use appropriate affordances. From this follows that the ecological approach to gameplay overrides the division of games as being digital and non-digital games.
Digital Materialities and Family Practices: The Gendered, Practical, Aesthetical and Technological Domestication of Play
Authors: Enevold Jessica
Published: September 2017

Digital gameplay is now firmly embedded in everyday practices in many Scandinavian homes. This paper deals with the constitution of such practices in families by taking a closer look at the material objects essential to play and their role in the “design of everyday life” (Shove et al 2007). It uses ethnographic methods and anthropological practice theory to attend to the domestic spaces of leisure and play, the home environment, where a large part of today’s practices of playing digital games takes place. It focuses on the stagings of material, not virtual, artifacts of gaming: screens, consoles and hand-held devices essential to play and their locations and movements around the home. It demonstrates how everyday practices – seemingly mundane scenographies and choreographies – practically, aesthetically and technologically determined, order everyday space, time and artifacts; and domesticate play and condition performances of family, gender and gaming. In the process, a history of the domestication of play unfolds.

Game Design in an Internet of Things
Authors: Coulton Paul , Burnett Dan , Gradinar Adrian , Gullick David , Murphy Emma
Published: September 2017

Whilst no consensus yet exists on how the Internet of Things will be realised, a global infrastructure of networked physical objects that are readable, recognizable, locatable, addressable and controllable is undoubtedly a compelling vision. Although many implementations of the Internet of Things have presented these objects in a largely ambient sensing role, or providing some form of remote access/control, in this paper we consider the emerging convergence between games and the Internet of Things. This can be seen in a growing number of games that use objects as physical game pieces to enhance the players’ interaction with virtual games. These hybrid physical/digital objects present game designers with number of interesting challenges as they i) blur the boundaries between toys and games; ii) provide opportunities for freeform physical play outside the virtual game; and iii) create new requirements for interaction design, in that they utilise design techniques from both product design and computer interface design. Whilst in the past the manufacturing costs of such game objects would preclude their use within games from small independent games developers, the advent of low cost 3D printing and open software and hardware platforms, which are the enablers of the Internet of Things, means this is no longer the case. However, in order to maximise this opportunity game designers will need to develop new approaches to the design of their games and in this paper we highlight the design sensibilities required if they are to combine the digital and physical affordances within the design of such objects to produce good player experiences.
The Case for Computer-Augmented Games
Authors: Bergström Karl , Björk Staffan
Published: September 2017

In this article we introduce and explore the concept of Computer-Augmented Games – the use of computer technology to provide support or tools for gaming activities rather than use the technology as the complete mediating platform. Several examples of these games are presented and placed in a design space using a multi-dimensional typology of games approach. Based on this, possible future directions for using computers to support gameplay are discussed.
Affect, Responsibility, and How Modes of Engagement Shape the Experience of Videogames
Authors: Veale Kevin
Published: September 2017

The experience of videogames is distinct from other forms of mediated storytelling because the person playing the game can come to feel responsible for events and characters within a fictional world due to dynamics within what Brendan Keogh calls the ‘messy, hybrid assemblage’ of videogame play: Games function through modes of engagement where people need to make decisions and take actions in order to proceed through a hybrid text, in a context that the player is affectively invested in, and which is personally relevant to both the player and their situation.  A perception of responsibility grows out of that agency, since the player’s decisions have a meaningful impact on a world and characters that they already invested in treating as if they were real.
On Chairing a Games Research Conference
Authors: Zagal José P.
Published: September 2017

Chairing an academic conference, especially one like DiGRA, is a great honor and a great responsibility: it grants you a fair amount of power, at least for a short amount of time. I thought I would take advantage of that power and this platform to share my personal thoughts and opinions on what it means to run an academic conference in this field. In doing so I hope to clarify some of the things that, to me at least, were opaque about the process of chairing a conference. While I knew that chairing was a lot of work, understanding what that work was, how things should be done, and why they should be done a certain way was not clear to me until I was in the middle of it all. I hope that what follows serves two purposes: (1) clarify some of what is involved in chairing a conference in hopes that others (including students and new members to the field) can better understand some of the practices of this academic community and (2) encourage reflection and discussions on our practices and how they could be improved.
Introduction
Authors: Björk Staffan , Fuchs Mathias
Published: September 2017

One of the aims of the Transactions of the Digital Games Research Association (ToDiGRA) is to collect the best received work presented at the DiGRA conferences. This special issue collects some of the highlights from the 2015 edition of the DiGRA conference held in Lüneburg, Germany(May 14-17). The conference theme of “Diversity of play: Games – Cultures – Identities” invited submissions that reflected upon the diversityof games and gaming and this compilation features some of the bestwork on that. As usual, the invited keynote speeches are not an integral part of the Transactions. We did however publish the keynotes in a separate open access publication that you might want to read in parallel with the peer-reviewed articles in this issue. You can find the booklet with the title “Diversity of Play” (ed Mathias Fuchs) published by meson press in Lüneburg available for free download at: http://meson.press/books/diversity-of-play/
Are You Out of Your Mind? Focalization in Digital Games
Authors: Allison Fraser
Published: September 2017

This paper demonstrates how the concept of focalization, as defined by Gérard Genette (1980), can be used to analyze experiences of subjectivityin digital games. Strategies to create internal focalization are identifiedin games’ audiovisual presentation, provision and restriction of private knowledge, and ludic affordances. This provides a framework for games that seek to present diverse or distinctive perspectives, to allow players to access modes of thinking that accord with a mind other than their own. This framework can assist researchers, critics, and designers to identify ways in which digital games express elements of internal focalization that communicate the mental patterns of a perspective character.
The Role of Gaming Platforms in Young Males' Trajectories of Technical Expertise
Authors: Baxter-Webb Joe
Published: September 2017

Studies of gender in videogame culture have often suggested that games provide a source of informal learning about technology, and that the perceived masculinity of the medium means that this benefit goes mainly to boys. The author’s research interrogates and expands upon this “technosocialization” theory of games. This paper presents a case-study based on interviews with male students (n = 18) studying ICT (Information and Communications Technology) in the UK, and illustrates the complexity of relationships between gaming and their interest (or indifference) toward computing careers.
Worldfulness, Role-enrichment & Moving Rituals: Design Ideas for CRPGs
Authors: Champion Erik
Published: September 2017

Roles and rituals are essential for creating, situating and maintaining cultural practices. Computer Role-Playing games (CRPGs) and virtual online worlds that appear to simulate different cultures are well known and highly popular. So it might appear that the roles and rituals of traditional cultures are easily ported to computer games. However, I contend that the meaning behind worlds, rituals and roles are not fully explored in these digital games and virtual worlds and that more needs to be done in order to create worldfulness, moving rituals and role enrichment. I will provide examples from The Elder Scrolls IV: Oblivion and The ElderScrolls V: Skyrim (Bethesda, 2006, 2011) to reveal some of the difficulties in creating digitally simulated social and cultural worlds, but I will also suggest some design ideas that could improve them in terms of cultural presence and social presence.
