Victorian Beauty: Ruskin’s Changing Ideals
Authors: Birch Dinah
Published: September 2022

Ruskin, and to some extent his followers, is often seen as the great Victorian prophet of beauty. In his early writing he invests beauty with the force of religious truth. In a passage intended for the second volume of Modern Painters (1846), he writes of the power of an Alpine avalanche teaching him ‘what till then I had not known — the real meaning of the word Beautiful. With all that I had ever seen before — there had come mingled the associations of humanity — the exertion of human power — the action of human mind. The image of self had not been effaced in that of God […] . It was then that I understood that all which is the type of God’s attributes […] can turn the human soul from gazing upon itself […] and fix the spirit […] on the types of that which is to be its food for eternity; — this and this only is in the pure and right sense of the word beautiful’ (Works, IV, 364–65). But he was never entirely content with this definition, and only two years later writes of the landscape of the Jura in very different terms: ‘Those ever springing flowers and ever flowing streams had been dyed by the deep colours of human endurance, valour, and virtue; and the crests of the sable hills that rose against the evening sky received a deeper worship, because their far shadows fell eastward over the iron walls of Joux and the four-square keep of Granson’ (VIII, 223–24). In his later work he retreats from his youthful belief that the value of beauty is distinct from human character, claiming instead that ‘endurance is nobler than strength, and patience than beauty’ (XVI, 372). The perspective of his work shifts to the social and political, and he turns from the analysis of beauty to a critique of the circumstances that excluded men and women from its creation, or its presence. As he became more interested in justice, he grew less interested in beauty. To see the celebration of beauty as the primary motive of his work is to mistake the nature of its persistent challenge.
Militancias visuales. El pensamiento estético y político de Gabriela Samper en su obra
Authors: Bonilla Sanabria Catalina del Mar , Cristancho Altuzarra José Gabriel
Published: September 2022

Este artículo, resultado parcial de una investigación de tesis doctoral, tuvo como objeto de estudio la obra de Gabriela Samper. Una mujer colombiana pionera del audiovisual etnográfico y la cultura visual, quien inició una corriente de investigación documental que constituyó un reservorio de contenidos y memorias que le permitieron una extensa participación en la realidad política y cultural colombiana de la época (1965-1974). El objetivo de este artículo es caracterizar el pensamiento estético y político de Gabriela Samper, apropiando como objeto de estudio algunas de sus obras cinematográficas más emblemáticas. La metodología consideró un análisis estético del contexto político y un estudio técnico de algunos de sus cortometrajes más importantes, con un prototipo de análisis formal establecido por el autor para la reconstrucción de su ideología y experiencia de vida artística. Tomando como fuentes complementarias se incluyeron entrevistas realizadas a personas conocedoras de su obra. El análisis permitió ubicar a Gabriela Samper en la historianacional, la crítica, los movimientos estéticos y su fuerte relación con el contexto cultural y social; este corpus de documentales sobre la identidad colombiana son una mirada diferente para esta época, desarrollando así posturas más controversiales y contemporáneas a través de enlaces simbólicos que visualmente permiten entender la postura crítica de la artista.
Paisajes sonoros: las primeras propuestas experimentales del CAVS para la regeneración urbana y paisajística, a partir de la creación de ambientes sonoros
Authors: Lorenzo Cueva Covadonga
Published: September 2022

El presente artículo muestra una serie de paisajes sonoros realizados bajo la dirección de György Kepes en el Center for Advanced Visual Studies (CAVS) del Massachusetts Institute of Technology (MIT), a principios de los años setenta. Todos ellos se orientaban hacia la regeneración de espacios urbanos ypaisajísticos, que estaban viéndose gravemente afectados por la degradación ambiental producida por un crecimiento urbano descontrolado, a partir de intervenciones sutiles que surgían desde la experimentación con el sonido y que promovían el trabajo colaborativo entre artistas de diversas disciplinas. Su estudio puede resultar de interés, en nuestros días, por la calidad de las obras presentadas y, también, para ayudarnos a repensar nuevas formas de mejorar el entorno urbano que nos rodea y a proyectar espacios más dinámicos y sensibles al medioambiente y a las necesidades de unos ciudadanos cada vez más comprometidos con el desarrollo sostenible de las ciudades. Así, podrían servir de referencia en proyectos orientados a la conservación del paisaje natural, que aún es posible encontrar en algunas áreas periurbanas de las ciudades, buscando preservar sus valores ambientales a partir de la creación de paisajes sonoros, o bien para regenerar áreas urbanas degradadas por el impacto ambiental, mejorando problemas de contaminación ambiental y acústica.
Tecnocreatividad aplicada al diseño de arte sonoro: contribuciones de campo a la intrahistoria pandémica para la tecnoalfabetización
Authors: Tornero Lorenzo Paz
Published: September 2022

El presente artículo recoge las experiencias educativas realizadas en las asignaturas de Audiovisuales de 1º curso y Proyectos Audiovisuales de 4º curso en el Grado de Bellas Artes de la Universidad de Granada, España. Como objetivo, se plantea componer una pieza sonora experimental digital (o collagesonoro) partiendo de una grabación previa que se relaciona con una acción física y cotidiana. Tendremos en cuenta el incremento del uso de las herramientas virtuales en época de pandemia, para introducirlas como materiales de trabajo. Definimos como acción cotidiana, la grabación de un suceso que ocurre durante la vida diaria. Este evento viene dado por una serie de imágenes que dan forma a dicha acción, realizando el complejo ejercicio de traducir la actividad visual en el diseño de una experiencia sonora. Se pretende detectar la relevancia y los distintos significados de la imagen que coexisten en nuestra sociedad digital atacada por la masiva información visual de los medios de comunicación, los múltiples mensajes en el espacio público y los dispositivos electrónicos. Una vez definido el ejercicio sonoro a diseñar, entre la acción elegida y el análisis de su narratividad visual,los estudiantes profundizarán en los distintos discursos de estas imágenes por medio de la práctica sonora. Por tanto, será principal reflexionar sobre el procedimiento a seguir para transitar desde nuestro imaginario visual a un soundscape. La práctica del arte sonoro permite comprender las múltiples lecturas de la imagen contemporánea, una vez se asimilan sus fundamentos teóricos, creativos y referentes artísticos, y ayuda a los futuros creadores aproducir originales reinterpretaciones de la cultura visual actual, teniendo en cuenta la falta de “tecnoalfabetización” de las nuevas generaciones por el uso indiscriminado, cotidiano y automático de los dispositivos electrónicos.
Cartografía de medios de representación arquitectónica en relación con resultados de aprendizaje. Caso de estudio: Programa de Arquitectura, Universidad Nacional de Colombia, sede Manizales
Authors: Roldán García Andrés Felipe , Escandón Suárez Paula Andrea
Published: September 2022

El proceso de enseñanza-aprendizaje de las técnicas de representación para arquitectos pasa por diferentes etapas en las que se requiere evaluar los resultados de aprendizaje teniendo en cuenta procesos cognitivos y las particularidades de las herramientas tradicionales y contemporáneas que semezclan para permitir idear, desarrollar y comunicar el proyecto arquitectónico. El siguiente estudio muestra una caracterización de los medios de representación para arquitectura, teniendo en cuenta diversas variables en el proceso proyectual, las cuales se clasifican según el caso de estudio planteado en las asignaturas del área de representación con los estudiantes de Arquitectura de la Universidad Nacional de Colombia en la sedeManizales. El objetivo se enfoca en reconocer la relación de los medios de representación con los resultados de aprendizaje para este programa académico. El método empleado es de carácter cualitativo, a través de reconocimiento de flujos de trabajo e inventario de medios en relación con los resultados de aprendizaje tomados del proyecto presentado para la reforma del programa y el caso de estudio en asignaturas del área de representación. El resultado del estudio presenta una cartografía de medios de representación en arquitectura, que permite navegar e identificar diferentes medios y sus características asociadas a los resultados de aprendizaje según el tipo de cognición, donde se especifican tres tipos de relaciones entre pensamiento concreto, posconcreto y formal y los medios de representación, analógicos, digitales y mixtos.
La arquitectura del horizonte y la tierra en la obra y dibujos de Sverre Fehn. Los análisis de Pietilä y Utzon
Authors: López Cotelo Borja Ramón , Amado Lorenzo Antonio , Berkin Genco
Published: September 2022

Metodología y objetivos: Con el objetivo de comprender las inquietudes teóricas y conceptuales que estructuraron la obra del arquitecto noruego Sverre Fehn (1924-2009), se han explorado los textos y dibujos contenidos en cuadernos cuyas páginas llenó Fehn a lo largo de sus más de 50 años de actividad profesional. El análisis de estas fuentes directas, conservadas en el Nasjonalmuseet for Kunst, Arkitektur og Design de Oslo y su puesta en relación contextos que sobre el arquitecto escribieron críticos y compañeros —destacando Per Olaf Fjeld y Christian Norberg-Schulz, ambos con vínculos biográficos con Fehn—, ha permitido concluir que dos fueron las ideas básicas subyacentes en la producción del noruego: por un lado, el horizonte, que entendió como desafío, patria de lo desconocido, motor de la imaginación de los hombres hasta que la constatación de la esfericidad de la Tierra mermósu capacidad para inspirar el pensamiento irracional; por otro, el encuentro de la arquitectura con el terreno, con esa masa que el arquitecto manipula hasta descubrir que es precisamente en la confrontación dramática entre naturaleza y hombre donde nace la belleza, y que en ese duelo la arquitectura reconoce sus límites. Resultados: Al comparar estas reflexiones —especialmente las relativas a la oposición entre arquitectura y naturaleza— con lospostulados defendidos por algunos de sus contemporáneos, se ha evidenciado un Sverre Fehn muy alejado de los planteamientos de otros arquitectos con los que compartió contexto geográfico y temporal como Reima Pietilä, al tiempo que se ha desvelado su profunda convergencia con el enfoque del danés Jörn Utzon, con quien había colaborado profesionalmente en su juventud.
Estimation of coal density using a 3D imaging system: RhoVol
Authors: Nakhaei F. , Campbell Q.P. , le Roux M. , Botlhoko S.
Published: September 2022

The results of coal sink and float tests are plotted as washability curves. Analysis of these curves indicates the most effective method by which the coal can be cleaned. Sink and float experiments are sampling-dependent, destructive, and use toxic chemicals. The present research introduces an alternative method based on a 3D imaging system called RhoVol, in which the density of individual particles is determined from mass and volume measurements. A quantitative error analysis was conducted on coal sample density measurements obtained by RhoVol, and the main factors influencing the errors identified and investigated. The results show that the drawback of this technique is related to its not being able to detect hidden concavities in the particle, resulting in an overestimation of particle volume. Furthermore, it is difficult to capture the impact of porosity and cracks on the volume of coal particles obtained from 3D silhouette images. This mismatch between the RhoVol data and sink and float test results has led to attempts to apply neural network (NN) and linear regression techniques to produce a fully reliable model for correction and estimation of coal density. The NN approach offers superior predictive capability over linear regression, and the estimated density distribution is in line with the sink and float analysis. The root mean square error in estimation of density using the NN model was less than 0.05 g/cm3.
Petrographic and geochemical characteristics of beneficiated metallurgical coal from the No. 6 Seam, Tshipise sub-basin, Soutpansberg coalfield, South Africa
Authors: Sebola M.J.T. , Drennan G.R. , Wagner N.J.
Published: September 2022

The Soutpansberg Coalfield hosts South Africa's hard coking coal reserves. However, coals in this region are understudied compared to other coalfields in the country. This study characterizes the properties of fine-float fraction samples extracted from a wide diameter borehole core in the Makhado Project, Tshipise sub-basin, Soutpansberg coalfield. Conventional analyses were used to determine the coal quality, petrographic composition, mineralogy, geochemistry (including trace element and rare earth element composition), and free swelling index of samples from six coal horizons and three partings from the economic No.6 Seam. The coal samples are classified as medium rank bituminous C coals (0.88 %RoVmr, 0.92 %Rmax) and are highly vitrinitic in composition (97 vol% mineral matter free (mmf)). The samples show strong caking potential (FSI of 9). The total rare earth concentrations range between 570 and 3193 ppm in the ash samples. Preliminary analysis show all but two samples are promising sources of rare earth elements as the total concentrations exceeded the 1000 ppm cut-off grade. Further research is required to confirm these preliminary findings.

Three Dimensional Vibration of an Isotropic Plate Enclosed in a Rigid Body
Authors: GUL Ufuk , AYDOĞDU Metin
Published: September 2022

In this study, vibration of plates embedded in a rigid enclosure has been investigated analytically for the first time in the literature. It is assumed that the isotropic plate is always in contact with outer enclosure. Therefore, the normal displacement at a boundary surface is constrained but tangential displacement at a surface is allowed. The displacement field is assumed in trigonometric function form. This analytical solution is the only available exact solution of three-dimensional isotropic plate. Numerical results were presented for various geometrical parameters. It is believed that the present formulation and the results can be used as a benchmark for the numerical methods where the exact solution is not possible.
ANCAMAN KEPUNAHAN DAN STRATEGI PEMERTAHANAN TRADISI SINRILI DI MASYARAKAT MAKASSAR
Authors: Fitriani Fitriani , Fitriana Fitriana , Nasir Nur Hafsa
Published: September 2022

This study aims to determine the factors causing the threat of extinction and the strategy of maintaining the sinrili tradition in the Makassar community. This study is based on library research with a descriptive approach. The results of this research reveal that the factors that cause the threat of extinction of the sinrili tradition in the Makassar community are:(1) Work as a singer is not considered as a main profession in Makassar, and is only seen as a side job. (2) The development of modern music which is more attractive to the younger generation poses a challenge to this tradition. (3) The quantity of sinrili in Makassar has deteriorated because the three sinrili maestros have died. There are five strategies for maintaining the sinrili tradition in the Makassar community, namely (1) the provision of a forum by the Government, in this case, the Office of Culture to form a sinrili community (2) developing the interest of the younger generations by holding cultural festivals and having sinrili competitions (3) teaching the sinrili tradition through art circles or clubs (4) documenting the sinrili oral literature, and (5) including the sinrili tradition in the teaching materials of local content subjects of Makassar regional culture. From the results of this research, it can be concluded that currently the process of regenerating singers is still going on through the process of legacy and learning, but at present, there is only one person who is good at singing and performing sinrili, namely Arif Rahman Daeng Rate. Thus, the condition of the sinrili tradition requires serious attention from all parties so that this tradition will remain sustainable and not go into extinction.
CHEF MINORITAS DI TEMPAT KERJA: PEREMPUAN DI DAPUR PROFESIONAL
Authors: Septiani Intan Yusan , Siscawati Mia
Published: September 2022

ABSTRACT

Cooking activities in the traditional kitchen or in the domestic area—which are supposed to be the domain of women—are interpreted as an obligation as well as a form of a woman’s service to her family, spouse, children, and even other people who are close to her life. In other words, cooking in the domestic area is an undefined job. Regardless of the fact, when cooking shifted to the public space, it turned into a professional job , a work area which was later known as the professional kitchen. People who work in a professional kitchen are given the title professional chef. Ironically, such a professional kitchen, often thought to be easily controlled by women—who for centuries have always been related to cooking activities—is actually controlled and dominated by men, starting from culinary studies (tata boga) to the industry. As a skill, cooking is actually an activity that can be performed by anyone, regardless of gender. In reality, cooking activities, in both traditional and professional kitchens, place women in a marginal and subordinate position. To learn why women, who are often considered as “the queen of the traditional kitchen”, find it difficult to control and dominate professional kitchens, we examine a number of studies that have analyzed the professional life of female chefs as well as various forms of gender inequality in the chefs’ workplace or the professional kitchen.

 
MEMBACA PERSOALAN HIJAB DAN OTONOMI PEREMPUAN MELALUI EPISTEMOLOGY IGNORANCE
Authors: Pertiwi Saniyah , Asnawi Naupal
Published: September 2022

Apart from its religious values, the hijab has currently developed into a lifestyle. The issue concerning the hijab in Indonesia has evolved over time with a fascinating complexity that is worth to be examined. The Indonesian people who have the habit of questioning the decision to wear or not to wear the hijab illustrates that the choice of Indonesian women is not considered as a personal matter. This research will discuss how the phenomenon of “questioning the decision to wear or not wear the hijab” is based on the epistemology of ignorance, which investigates and explains how ignorance is formed and preserved in this phenomenon. The revelation of the women’s complex experiences concerning their hijab is part of the epistemology of ignorance. This research uses a literature study method to obtain sources and present data, followed by a critical reflection method to explore and reflect on ignorance in the phenomenon under study. This article concludes that interfering in women’s decisions to wear or not to wear the hijab is a form of ignoring women’s subjective experiences and women’s autonomy because it creates misunderstandings and violates human rights.

In addressing the 21st century neocolonial research condition, in this article the au- thors firstly discuss how academia in general, and elt in particular, may configure as oppressive colonizing sites. Secondly, they introduce their own experience as pre- service and in-service educators who took part in pedagogy of possibilities (pop) at a university in Tunja, Colombia. Indigenous principles like interconnectedness and relationality and Chicanx/Latinx concepts, such as bodymindspirit, path of cono- cimiento, and spiritual activism were foundational to these educators’ pop. To them, pedagogy was a political act to resist the disembodied/disengaged/dispassionate nature of teaching/researching/being in academia and beyond. This four-year crit- ical-community autoethnography, uses testimonies, journals, and artistic creations as knowledge-gathering methods to analyze how decolonizing teaching-research practices informed the re-signification of these educators’ personal and professional identities. Theoretical coding revealed that pop permitted participants to engage in decolonial practices of self-recognition, re-construction, empowerment, growth, and healing. The analysis also revealed that decolonizing the self leads to the adoption of a positionality where values such as care and respect for one’s self and communities are paramount to move forward social-justice-critical-decolonial agendas. The results suggest the need to re-signify elt pedagogical and educational practices beyond neo- liberal agendas which propose rankings, individualism, and competition.
Disrupting Colonial Tensions in Initial Language Teacher Education: Criteria Based on Critical Interculturality
Authors: Granados-Beltrán Carlo
Published: September 2022

Colombian English Language Teaching (ELT) is experiencing a paradigmatic change guided by the decolonial turn. This turn has enriched the debate about the implementation of a bilingual policy in Colombia, its impact on languages otherthan English, the purposes of learning English in the country, and English teacher practices and identities. This article shares the results of a critical ethnography that collected data from students and teacher educators from elt preparation programs and institutional and legal documents. Results indicate that, in Colombian elt, there are six discursive tensions representing coloniality. These are (a) English teachers as instructors or as educators; (b) native or non-native English speakers; (c) poor image of foreign language teachers as opposed to an idealized language teacher; (d) instrumental or cognitive and intercultural purposes for learning English; (e) emphasis on disciplinary knowledge or on interdisciplinary knowledge; and (f ) division or integration between theory and practice. To counter these tensions, a set of criteria are proposed. These criteria are: (a) elt preparation graduates are professionals in language pedagogy; (b) they are multilingual educated teachers; (c) they are well-rounded professional educators; (d) English is a means of recognizing diversity; (e) elt preparation programs embrace interdisciplinarity as a decolonizing option; and (f ) ELT preparation programs promote praxis. To conclude, the criteria proposed aim to shift initial language teacher education from an instrumental vision to a reflexive one, considering what is being learned, how, with whom, in what contexts, and the reasons that justify it.
Saberes sobre conflictos y reconciliaciones en la práctica pedagógica de docentes de inglés en formación
Authors: Aguirre Edgar , Ubaque-Casallas Diego , Salazar-Sierra Adriana , López-Hurtado Maria Eugenia
Published: September 2022

Este artículo analiza y documenta los saberes pedagógicos sobre conflictos y reconciliaciones que emergen en la práctica pedagógica de dos docentes en formación, que enseñan inglés como lengua extranjera (ile) en colegios de Bogotá, Colombia. El estudio empleó eventos narrativos de las experiencias de las docentes-practicantes en contextos pedagógicos conflictivos. Estas experiencias se analizaron a través de un enfoque narrativo, desde un lente de pensamiento decolonial, para abordar formas localizadas de saberes que son alternos a estructuras de producción de conocimiento hegemónico. Los resultados muestran que a partir de prácticas fundadas en el reconocimiento del otro, el entendimiento del conflicto como connatural a los sujetos y el diálogo entre pedagogías de lengua tradicional occidental y pedagogías otras en el aula, las docentes en formación empezaronn a fracturar lógicas tradicionales en la enseñanza de ile. Esto les permitió reconfigurar la construcción de sus estudiantes como sujetos sociales y la enseñanza del inglés como una práctica social humanizadora. Dichos resultados sugieren la necesidad de que las instituciones que forman docentes visibilicen más las experiencias generadoras de saber de los docentes en formación en su práctica pedagógica.
La compensación emocional y la dialéctica placer/sufrimiento en el trabajo
Authors: Gálvez Calderón Valeria Valentina , Bermúdez-Restrepo Héctor L.
Published: September 2022

El propósito es examinar las manifestaciones de placer y sufrimiento en el trabajo cotidiano causadas por las prácticas de “compensación emocional” que proponen los “Modelos Estratégicos de Administración de Recursos Humanos” en las grandes firmas multinacionales de auditoría, interpretando los relatos de un conjunto de contadores públicos. Se trata de una investigación cualitativa (enfoque hermenéutico) a través de entrevistas poco dirigidas examinadas con la técnica de análisis del discurso orientado textualmente (ADOT) de Norman Fairclough articulado con el método indiciario de Carlo Ginzburg. El estudio permite explorar la experiencia sensible de estos profesionales sin necesariamente asociarla a la búsqueda del aumento de la productividad y el desempeño. Se concluye que, el término “compensación emocional” es problemático, pues, aunque la organización del trabajo puede influenciar la percepción de la labor cotidiana y afectar su sensibilidad y su valoración subjetiva causando placer en ciertas ocasiones y sufrimiento en otras, las empresas no pueden pagar a sus trabajadores con emociones.

Published: September 2022

El objetivo del presente artículo es mostrar los efectos de la incidencia de la gestión humana en la estrategia de innovación en producto de pequeñas empresas del corredor industrial de Boyacá, Colombia. De una población total 947 empresas manufactureras, el estudio se aplicó por conveniencia a 17, concentradas en tres ciudades de Boyacá, a través de una investigación de tipo descriptivo con enfoque cualitativo mediante la aplicación de entrevistas y un cuestionario a escala Likert, los datos se procesaron con la ayuda de los softwares SPSS para datos cuantitativos y Atlas Ti para datos cualitativos. El estudio devela la claridad que tienen los gerentes y jefes de recursos humanos sobre la importancia de aplicar buenas prácticas de gestión humana en pro de la mejora en la innovación, evidenciando el factor asociado a las condiciones económicas como la principal dificultad al momento de innovar, mientras que la cultura empresarial arraigada a métodos ortodoxos de contratación y selección, se evidencia como el mayor limitante para que la innovación realmente aporte al crecimiento de las organizaciones.
Motivaciones de los voluntarios corporativos y factores que influyen sobre ellas
Authors: Licandro Goldaracena Oscar Daniel , Yapor González Stefanía , Correa García María Patricia
Published: September 2022

El conocimiento de las motivaciones de los voluntarios es un insumo crítico para el diseño de estrategias de captación y retención en los programas de voluntariado corporativo. No obstante, su importancia, la investigación empírica sobre la motivación en este tipo de voluntariado es apenas incipiente y aislada. El objetivo de la investigación fue identificar la estructura de motivaciones de los voluntarios corporativos y estudiar si esa estructura depende de factores sociodemográficos y culturales de los voluntarios y de la práctica del voluntariado personal en instituciones sociales. Es un estudio de tipo correlacional apoyado en una metodología de tipo cuantitativo. Se aplicó un cuestionario auto-administrado a voluntarios de 13 empresas que en Uruguay implementan programas de voluntariado corporativo. Las motivaciones se midieron en base al Volunteer Functions Inventory, que es una herramienta validada y ampliamente aplicada para medir las motivaciones del voluntariado en organizaciones sociales. Los resultados obtenidos son consistentes con los de investigaciones realizadas en otros países, con la diferencia de que los motivos relacionados con el interés por adquirir conocimientos registraron un mayor peso relativo que los estrictamente altruistas. También se encontró que la estructura de motivaciones resultó ser independiente de la mayoría de las variables que caracterizan a los voluntarios, al tiempo que se registraron diferencias significativas al comparar entre voluntarios de distintas empresas. Entre las principales conclusiones se destaca que la motivación de los voluntarios corporativos combina motivos altruistas y egocéntricos, que la estructura de motivaciones de cada voluntario no parece depender de factores personales y que existen factores relacionados con la empresa que impactan sobre esa estructura.

“We Support Harm Reduction”: Frame Analysis of Canadian News Media Coverage of the Opioid Crisis
Authors: Ferguson Lorna , Eliasson Michelle
Published: September 2022

This study examines news media framing of the opioid crisis in Canada to advance an understanding of the dominant discourses and identify the narratives shaping public and policymakers’ opinions and preferred solutions. We conducted a content and frame analysis of 2,273 Canadian news articles published between January 2016 and December 2019. The analysis revealed that harm reduction and treatment were the preferred solutions instead of criminalization, and public health framing predominantly occurred. The overall tone emerged as empathetic and softer and, generally, the leading policy choices and opioid crisis were framed contradistinct from past drug epidemics.

L’essor du numérique bouleverse l’économie politique de la production indépendante. Cet article a pour objectif d’analyser les liens entre le réseau de langue anglaise du radiodiffuseur public canadien et la production indépendante dans le contexte des mutations technologiques et économiques. L’étude de nature qualitative recourt à l’analyse documentaire et à des entretiens semi-dirigés avec les responsables de la stratégie numérique du réseau public CBC et avec des producteurs indépendants. Le radiodiffuseur public s’adapte au numérique et les façons de faire des producteurs indépendants se modifient aussi dans un nouvel environnement audiovisuel caractérisé par un déséquilibre des rapports de force quant aux ententes commerciales avec la CBC et aux conditions de valorisation du contenu dans un contexte mondialisé.
Instagram as a Tool to Counter the Image of Countries as Unsafe: the Case of #LiveLoveLebanon
Authors: Nehme Raphaela
Published: September 2022

The emergence of social media has created new means of intercultural engagement. On Instagram, there is a growing trend of travel pages and travel bloggers whose aim is to introduce and share the highlights of the destinations they travel to. Locals in these destinations also wish to portray their country positively and promote it as a tourist destination, particularly in certain countries of the Middle East where there is the added challenge of an ‘unsafe’ image to combat. This research focuses on Lebanon to find out to what extent Instagram can be considered a means to this end, and if users who come across depictions of Lebanon on Instagram perceive the country as a potential tourist destination. The study draws on Said’s conception of the ‘other’ (1978), Hall’s system of representations (1980) and Pieterse’s hybridization paradigm (1996), and it used a mixed methods approach combining surveys and semi-structured interviews with Canadian participants. Findings broadly show that while Instagram can effectively be considered a tool to counter the ‘unsafe’ image of Lebanon, and while the country may be branded as a potential tourist destination to users who come across favorable depictions of it, algorithm restrictions limit the potential for such contents to fulfill their potential as they do not always reach users who perceive Lebanon to be an ‘unsafe’ place.
A study to evaluate feto-maternal outcome of trial of labour in previous cesarean patients: a prospective observational study at a tertiary care centre in India
Authors: Tambe Sanjaykumar G. , Mulay Ameya S.

Background: Vaginal birth after cesarean section (VBAC) is associated with shorter maternal hospitalizations, less blood loss and fewer transfusions, and fewer thrombo-embolic events than cesarean section (C-section). A 60 to 70% success rate of vaginal birth after previous C-section has been reported by many authors if the primary cesarean was done for nonrecurring indications the subsequent pregnancyMethods: A prospective observational study was conducted at Sassoon general hospital, Pune, India. The 100 patients who fulfilled the inclusion criteria were studied. Maternal and fetal outcomes were analysed.Results: Out of the total 100 cases with previous C-section, successful vaginal delivery was possible in 65% cases. Most common reason for failed attempt to vaginal delivery was failure of labour to progress (40%) followed by failure of induction (28.6%) and non-reassuring FHR (22.9%). Out of the total 35 cases with gestation age over 40 weeks, 51.4% underwent C-section delivery as compared to 26.2% with gestation age of less than 40 weeks (p<0.01). Scar rupture was observed in only a single case out of 65 vaginal deliveries (1.5%).Conclusions: Our study demonstrates that the attempt at the trial of vaginal delivery following a previous C-section, has an good success rate. The risk of unsuccessful attempt is increased by body mass index (BMI) >25, gestation ≥40 weeks and history of previous emergency CS while high success rate was seen with history of any vaginal deliveries. We thus recommend that pregnant woman with history of C-section should be given the option of trial of labour after caesarean (TOLAC), unless contraindicated.

Background: Abnormal uterine bleeding (AUB) is defined as a pattern of bleeding that does not correspond with the duration, amount and frequency of the flow of a normal menstrual cycle. The cause of AUB varies according to the age, endometrial response to hormones and its variations and other structural lesions. Endometrial sampling by endometrium curettage is safe and easy technique and its histopathological analysis is considered the gold standard for diagnosis of the etiology of AUB. Aims and objective was to evaluate the spectrum of endometrial histology in cases of AUB, to find out age wise incidence of AUB, and to find out age wise incidence of various histological pattern of endometrium in AUB.Methods: An observational study was conducted on dilatation and curettage material which were obtained from 110 women with a complaint of AUB attending the gynecology outpatient department (OPD) at tertiary care hospital, Rajkot, Gujarat during one year (August 2020 to July 2021).Results: Maximum number of cases of AUB were noted in the age group of (31-40) years (44 cases, 40%). Most common observed histopathological pattern in this study was normal cyclical patterns including proliferative endometrium (34.5%) and secretory endometrium (21%).Conclusions: Histopathological evaluation of endometrium is indicated in women over the age of 35 years presenting with AUB to rule out preneoplastic lesions and malignancies.

Published: September 2022

This is a case report presenting, gravida 3 para 2 live 1 with primary abdominal pregnancy. It is a potentially life-threatening form of ectopic gestation with an incidence of 1% of all the ectopic pregnancies. In this case, the patient delivered a full-term male baby. The baby cried immediately after birth. The patient was stable post operatively but on 10th POD, developed pancytopenia with pleural effusion. The pancytopenia was methotrexaate induced. She was admitted in ICU and was given oxygenation, folinic acid and higher antibiotics. She was discharged on 20th POD after vitally and hemodynamic stability. In this case, though the patient was managed effectively but abdominal pregnancy is associated with significant maternal morbidity and mortality. Therefore, early diagnosis of the case still remains the most important modality for efficient management of the patient.

Immune (idiopathic) thrombocytopenic purpura (ITP), an autoimmune disease characterized by destruction of platelets, is a hematological disorder that can present in both pregnant and non-pregnant patients. It can occur in any trimester but generally, platelet counts start to decline in early pregnancy and continue to decline until delivery. Unlike most pregnancy-related thrombocytopenia, which is usually mild, ITP can have devastating consequences for mother, fetus, and neonate. It is a diagnosis of exclusion, and management should be based on a multidisciplinary care approach. ITP in pregnancy requires careful monitoring and may need treatment to improve platelet counts before delivery. Corticosteroid is the most commonly used first-line therapy to stop further destruction of platelets. Here, we report a case of a 26-year-old multigravida with gestational age of 24 weeks, diagnosed with ITP during routine antenatal check-up. Patient was managed with various treatment combinations consisting of platelet transfusion, steroids and intravenous immunoglobulin (IVIG) to reach the optimal platelet level. The aim of the study was to provide guidance on how to manage a patient with ITP throughout pregnancy

Background: Online health information seeking is prevalent among patients nowadays and this might influence the medical consultation outcome and affect the patient-doctor relationship. Objective was to determine the prevalence of online health information seeking behavior among primary care clinics attendees in Bahrain and the impact on patient-doctor relationship.Methods: Patients attending primary care clinics in Bahrain were asked to complete a previously adapted self-administered questionnaire that studied demographical data, frequency of online use in general and for health-related information and pattern of online health information seeking including reasons searched for and sources used. The logistic regression analysis done to explore respondent’s characteristics with health seeking behavior online.Results: Ninety-seven percent (97%) of the study population used the internet and (94.7%) had searched for online health information. The two main types of information sought were disease-related information (88.7%) and complementary and alternative medicine (55%). Fifty-three percent used reliable sources (i.e., Ministry of Health (43.3%), hospital websites (14.9%), medical encyclopedias (e.g., PubMed and Medline plus) (17.4%).  Approximately (39.3%) use social networks to find information (including Facebook and Twitter). Convenience and usability were the main reasons (88.9%). Fifty-five percent (55%) asked or shared health information they found online with their doctor.Conclusions: Online health information seeking is highly prevalent in Bahrain among primary care clinic attendees. Sources were chosen mainly for their convenience, availability and being easily understood. A good number shared health information found online with their physicians. Physicians should be aware about patients’ online health seeking behavior and address that during consultation.
