“Canada Needs All Our Food-Power”
Authors: Strikwerda Eric
Published: May 2019

This article examines the political economy of nutrition as a state-sponsored strategy to extract greater productivity from industrial workers in both wartime and peacetime. During World War II, the state, together with its munitions-industry allies, broadly considered workers’ nutritional health as a critical component to achieving maximum wartime industrial production. Following the war, both the state and industry imagined the nutritional health of workers’ bodies as crucial to Canada’s postwar prosperity. Facilitating as well as frustrating these largely state-directed nutrition agendas was a combination of medico-scientific knowledge, the sometimes uncertain and unpredictable participation of both employers and workers, and wider national and international historical contexts.

 

Cet article examine l’économie politique de la nutrition en tant que stratégie parrainée par l’État pour accroître la productivité des travailleurs industriels, en temps de guerre comme en temps de paix. Au cours de la Seconde Guerre mondiale, l’État et ses alliés de l’industrie des munitions ont largement considéré la santé nutritionnelle des travailleurs comme un élément essentiel pour parvenir à une production industrielle maximale en temps de guerre. Après la guerre, l’État et l’industrie ont tous deux estimé que la santé nutritionnelle des corps des travailleurs était essentielle à la prospérité du Canada d’après-guerre. Faciliter mais aussi frustrer ces programmes nutritionnels largement dirigés par les États était une combinaison des connaissances médicales et scientifiques, une participation parfois incertaine et imprévisible des employeurs et des travailleurs, et des contextes historiques nationaux et internationaux plus vastes.
More Dangerous Than Many a Pamphlet or Propaganda Book
Authors: Luciuk Kassandra
Published: May 2019

For Ukrainian Canadian leftists, the 1920s represented a golden age of domestic cultural production. The strict hierarchy that constituted the communist movement in the 1930s was not yet extant, and the realm of possibilities was limited only by the imagination of the organization itself. The material produced in this period was neither crass agitprop nor cheap melodrama. Rather, it was bottom-up expressions of proletarian high culture and organic reflections of the social, economic, and political realities that constituted the experiences of Ukrainian progressives in Canada. As such, in the 1920s, the theatre served as the movement’s most effective vehicle for political propaganda and ethnocultural instruction.

 

Pour les gauchistes ukrainiens canadiens, les années 1920 représentaient l’âge d’or de la production culturelle nationale. La stricte hiérarchie qui constituait le mouvement communiste dans les années 1930 n’était pas encore existante et le domaine des possibilités n’était limité que par l’imagination de l’organisation elle-même. Le matériel produit à cette époque n’était ni grossier agitprop ni bon mélodrame. Il s’agissait plutôt d’expressions ascendantes de la haute culture prolétarienne et de réflexions organiques sur les réalités sociales, économiques et politiques qui constituaient les expériences des progressistes ukrainiens au Canada. En tant que tel, dans les années 1920, le théâtre constituait le moyen le plus efficace du mouvement pour la propagande politique et l’instruction ethnoculturelle.
“Maybe We Shouldn’t Laugh So Loud”
Authors: Nourpanah Shiva
Published: May 2019

My research explores the labour conditions experienced by foreign nurses employed in health care in the province of Nova Scotia, Canada, on temporary permits. I draw on ethnographic interviews to understand the nuanced ways in which foreign nurses feel welcomed in their local communities and workplaces, yet simultaneously remain subject to hostile racialized scrutiny. Nova Scotia is one of the least ethnically diverse provinces in Canada and one of the most economically impoverished. It faces a shortage of healthcare workers, exacerbated by the ongoing restructuring of the healthcare sector. These contextual factors contribute to the complicated push-pull matrix discussed by the temporary foreign nurses, who feel needed, but not wanted. This matrix cannot be dismissed as simply the racism and “backwardness” of local communities. Rather, it must be understood through a political economy focus on temporary foreign workers, restructured health care, and the normalization of a precarious labour landscape in which racialized foreign and local workers are pitted against each other.

 

Mes travaux de recherche portent sur les conditions de travail subies par les infirmiers et les infirmières étrangers de permis temporaire employés dans les soins de santé dans la province de la Nouvelle-Écosse, Canada. Je m’appuie sur des entretiens ethnographiques afin de saisir les façons nuancées dont les infirmiers étrangers se sentent bien accueillis dans leurs collectivités, et en même temps font encore l’objet d’un contrôle racialisé hostile. La Nouvelle-Écosse est l’une des provinces les moins diversifiées sur le plan ethnique au Canada, ainsi que l’une des provinces les plus économiquement démunies. Elle est en outre aux prises avec une pénurie de travailleurs de la santé, aggravée par la restructuration en cours dans le secteur de la santé. Ces facteurs contextuels contribuent à la matrice complexe du « pousser/tirer » examinée par les infirmiers étrangers temporaires qui se sentent nécessaires, mais non désirés. On ne peut écarter cette matrice comme s’il s’agissait simplement du racisme et du « retard » des collectivités locales. Elle doit plutôt être comprise en mettant l’accent à caractère de l’économie politique sur les travailleurs étrangers temporaires, les soins de santé restructurés, et la normalisation d’un marché du travail précaire dans lequel les travailleurs racialisés, étrangers et domestiques, sont dressés les uns contre les autres.
Practical Implications in Popular Consumer Behaviour Research
Authors: Annamalai Balamurugan , Varshney Sanjeev
Published: May 2019

Despite the frequent calls to bridge the academic-practitioner divide by making academic research easily comprehensible to practitioners, there are minimal discernible advances in this direction. The objective of this study is to identify the popular trends in academic research and
establish the relevance of scholarly works for managerial action. The study initially scrutinises the prominent topics in consumer behaviour between 2005-2016 using subject terms and the Google Scholar (GS) ranking of the reviewed papers. Following which, correspondence analysis is carried
out on the themes to check correlation, and then validated using content analysis. A total of 149 research articles with managerial implications on the prominent topics were considered. The themes that emerged were: marketing communication tools (advertising and promotion); influencing strategies
(pricing, selling and product offering); and customer reactions (loyalty and satisfaction). The implications common to the themes are consolidated and presented in a way that could act as a quick reference guide for practitioners. The review, though being limited to studies published in top-tier
marketing journals, is unique in that no other paper has previously focused exclusively on listing the academic findings of practical relevance that could aid managers in decision-making.
The heterogeneity of the Nordic journalism education models: The ‘academic’ and the ‘professional’ in the bachelor’s curricula
Authors: Jaakkola Maarit
Published: May 2019

This article conducts a comparison of the curricula in bachelor’s programmes in journalism in the Nordic countries. Typically, the journalism education in the Nordic countries has been assumed to share many similarities due to a shared media system, societal ideology and cultural homogeneity. The analysis examines the Danish, Finnish, Norwegian and Swedish curricula in terms of their orientations towards the academic and the professional traditions and goals. It is found that the Nordic journalism education inhabits a heterogeneity that does not fit into a single model; instead, bigger differences in integrating the academic and professional orientations can be seen within the countries rather than between them. The most significant inter-national differences can be found in the role of the final thesis and courses in methodology as well as in the length of the internship. It is suggested that the diversity reflects the increasing diversity and heterogeneity of the profession.
From Bali to Warsaw: The rise and fall of Bangladeshi newspapers’ attention to climate change
Authors: Rhaman Mofizur
Published: May 2019

Based on Downs’s theory (1972) of the ‘issue-attention cycle’, this article investigates the degree to which Bangladeshi newspapers paid attention to climate change-related issues over a three-week period of each past four COPs (Conference of the Parties), namely COP13 in Bali (3 – 15 December 2007); COP 15 in Copenhagen (7 – 18 December 2009); COP 17 in Durban (28 November – 11 December 2011); and COP 19 in Warsaw (11 – 23 November 2013). Observations indicate that media attention to climate change issues declined over this period globally, despite the fact that the principal objective of the COPs has not yet to this day been achieved. Based upon content analysis and in-depth interviews, this article concludes that the issue-attention curve took a Downsian shape over the period of the four selected COPs in general; there were, however, fluctuations within each COP. Domestic, social, cultural and institutional factors may have contributed to various waxings and wanings. Moreover, the intrinsic value of climate change issues as news has lost much of its force. The cultural-editorial factors that prioritize ‘exciting’ news no longer consider climate change as exciting, especially compared to issues related to politics, corruption and violence.
Media sustainability, ethics and democratization: Cases of Philippine media civil society organizations
Authors: Opiniano Jeremaiah M. , Romero Alexis Douglas B.
Published: May 2019

Non-profit media civil society organizations (MCSOs) help contribute towards democratization and towards improving the conduct of journalism in the Philippines. These MCSOs operate with meagre resources while producing independent stories and implementing advocacies such as journalist protection, freedom of information, responsible media and civic journalism. While MCSOs operate through predictable revenue models, how do they sustain their work and walk ethical tightropes in fulfilling their non-profit and journalistic missions? This case study research presents approaches by four Philippine MCSOs on linking media sustainability, democratization and ethics.
Staging Baghdad as a Problem of Development
Authors: Gupta Huma
Published: May 2019

This article examines a cinematic artefact from 1957 titled The Housing Program of Iraq, which contains rare footage of sarifa (reed and mud) settlements inhabited by rural migrants in mid-century Baghdad. The film, which was never finished, was produced as a collaboration between the Greek architect Constantinos A. Doxiadis and the director Demetrios Gaziades, who shot and edited the footage between Baghdad and Athens. Through this film Doxiadis intended to complement the Doxiadis Associates’ (DA) entry for the Iraq National Housing Exhibition and also to promote the modern housing projects designed by DA. In this period, various statist actors used the representational medium of documentary film in an attempt to redefine the boundaries of Iraqi citizenship. This film, thus, offered a cinematic portal into an other Baghdad, which was staged as the problem of development. Subsequent scenes narrated the solution to these neighbourhoods and positioned a family in a modern low-income house to animate the film’s developmental fantasy. The film projected universal Iraqi home ownership as a form of citizenship where the house was an instrument to facilitate financial, legal, and social agreements between rural migrants and the Iraqi state. By interrogating the methodological question of how to assemble an archive of ephemeral and subaltern places, this essay suggests expanding our notion of historiographic evidence to understand the intertwined relationships between the politics of development and architecture, and their representation in media.
Reconstructing the Muslim Self in Diaspora: Socio-Spatial Practices in Urban European Mosques
Authors: Becker Elisabeth
Published: May 2019

Scholarship on mosques in Europe largely reflects public debates over the visibility and (in)civility of large diaspora Muslim populaces. This paper argues that postmigrant communities forge or dismantle boundaries with the mainstream through spatial practices in the mosque. Through a comparative study of two large representative mosques in Europe – the Şehitlik Mosque in Berlin and the East London Mosque – this paper shows how mosque communities employ local and transnationally linked spatial practices in order to reconstruct collective identities in diaspora. The mosque becomes a spatial opportunity in which post-migrant Muslim populaces engage with, and in, the two capital cities at hand (Berlin and London), rather than the subject of ongoing debates over national belonging. In both cases, the space of the mosque is used to espouse specific visions of collective identity and belonging, in spite of myriad exclusions. Analysing the spatial practices of mosque communities opens new opportunities for understanding the reconstruction of Muslim selves in diaspora.
Podium Podcast and the freedom of podcasting: Beyond the limits of radio programming and production constraints
Authors: Sellas Toni , Solà Sergi
Published: May 2019

The evolution of the Internet and the impact of digitalization have led the radio industry to try new production, distribution and commercialization strategies. In Spain, radio on the Internet began in the mid-1990s, and years later, in 2005, broadcasters incorporated podcasting. For more than a decade, they have used podcasts as a distribution tool, but in recent years, they have started to offer new content through podcasting. In June 2016, PRISA, one of the main Spanish media groups, took a step further with the launch of Podium Podcast. It is a new brand and platform, with a specific catalogue of native podcasts created and delivered taking podcast listeners into account. Podium Podcast is part of PRISA’s digital strategy, but it also shows a new approach to podcasting by the radio industry. Podcasters in Podium Podcast feel free of radio programming conventions and have the opportunity to experiment with content that does not fit into current radio stations’ schedules. Podium Podcast expands the Spanish podcasting sphere and contributes to the popularization of podcasts. However, we wonder to what extent it is a threat to independent podcasters and if it might contribute to the colonization of the field by the mainstream.
On what it means to be free: Radio as a tool of desistance for formerly incarcerated women in Adelaide, Australia
Authors: Anderson Heather , Bedford Charlotte
Published: May 2019

Women and girls make up only a small percentage of the overall prison population; however, there has been a significant increase in their representation, most notably over the past twenty years. Despite this, fundamental understandings of the role of prisons, as well as issues around recidivism and desistance are based on a male norm, failing to meet the needs of women affected by the criminal justice system. This article outlines the findings from an ongoing grassroots action research project conducted with a support group for women of lived prison experience, based in Adelaide, South Australia, to investigate radio production as a means for supporting women in their transition to life outside of prison. It draws on observations made over a two-year period of radio production and thematic content analysis to investigate the role of community radio as a tool of desistance for formerly incarcerated women.

Published: May 2019

Objective: The resistance of fungi and bacteria to the available antimicrobials has increased and the development of alternative products to control them has become a very requirement. The use of plant products could be a viable option due to the efficacy, viability, and availability they present. Thereby, this study evaluated the effect of R. officinalis L. extract on C. albicans and S. mutans biofilms, by the total protein level analysis presented by the microorganisms. Material and Methods: For this purpose, monomicrobial biofilms were formed for 48 h and exposed to the R. officinalis L. extract for 5 min. Then, total protein quantification was performed by Lowry method. Results: The analysis showed significant total protein reduction of the biofilms after exposure to the plant extract, with 39 ± 11%, for C. albicans, and 32 ± 11%, for S. mutans. Conclusion: R. officinalis L. extract decreased the total protein level in both biofilms. Thus, C. albicans and S. mutans protein composition could be a target for action of antimicrobial agents.KeywordsBiofilms; Candida albicans; Proteins; Rosmarinus officinalis; Streptococcus mutans.

Objetivo: Bio-Oss is a xenogene bone graft in which all organic components are removed while retaining their natural mineral architecture. Therefore, the aim of this study was to evaluate, through a literature review, the benefits of using Bio-Oss for tissue regenerative treatment prior to implant placement. Material and Methods: a search was performed in Pubmed (Medline) in order to identify articles published in English between January 1, 2000 and June 31, 2018, where the Bio-Oss graft was used prior to implantation of implants in humans. A total of 40 studies were selected for detailed analysis. From this analysis, 18 articles were identified for inclusion in this review. Results: the articles analyzed in the review showed several beneficial effects of this xenograft, such as: positive osteoconductive properties, recovery of bone heights at sites with severe atrophies, slow xenograft reabsorption suggesting long term stability, survival rates and success of implants placed in grafted sites ranging from 91 to 100% in several studies. Conclusion: the use of bio-oss as a bone substitute is a viable alternative in the placement before dental implants, being used in clinical practice and with proved efficacy in several studies, due to its similarity with the bone and its high level of osteoconductivity.KeywordsBio-Oss; Bone Graft; Implants.

Authors: Cilingir Aylin , Ozsoy Alev , Mert Eren Meltem , Behram Ozge , Dikmen Benin , Ozcan Mutlu
Published: May 2019

Objective: The objective of this study was to evaluate the compressive strength, flexural strength and flexural modulus of high-viscosity, low-viscosity bulk-fill, and conventional nano-hybrid resin composite materials alone and when covered with nano-hybrid resin composite at different incremental thicknesses on the bulk-fill composites. Materials and Methods: Specimens (N=60) were fabricated from the following materials or their combinations (n=10 per group): a) conventional nano-hybrid composite Z550 (FK), b) high-viscosity bulk-fill composite (Tetric N Ceram-TBF), c) low-viscosity bulk-fill composite SDR (SDR), d) Sonicfill (SF), e) SDR (2 mm)+FK (2 mm), f) SDR (4 mm)+FK (4 mm). After 24 h water storage, compressive strength was measured in a universal testing machine (1 mm/min). Additional specimens (N=40) (25x2x2 mm3) were made from FK, TBF, SDR and SF in order to determine the flexural strength and the flexural modulus, (n=10) and subjected to three-point bending test (0.5 mm/min). Data were analyzed using one-way ANOVA and Tamhane’s T2 post-hoc tests (p<0.05). Results: The mean compressive strength (MPa) of the nano-hybrid composite (FK) was significantly higher (223.8±41.3) than those of the other groups (123±27 - 170±24) (p<0.001). SDR (4 mm)+FK (2 mm) showed significantly higher compressive strength than when covered with 4 mm (143±30) or when used alone (146±11) (p<0.05). The mean flexural strength (159±31) and the flexural modulus of FK (34±7) was significantly higher than that of the high- or low-viscosity bulk-fill composites (p<0.001). The mean flexural strength of SF (132±20) was significantly higher compared to TBF (95±25) (p<0.05). Conclusion: Bulk-fill resin composites demonstrated poorer mechanical properties compared to nano-hybrid composite but similar to that of SF. Increasing the thickness of low-viscosity bulk-fill composite (SDR) from 2 to 4 mm underneath the nano-hybrid composite (FK) can improve the mechanical properties of the bulk-fill composites. KeywordsBulk-fill composites; Compressive strength; Flexural modulus; Flexural strength; Mechanical properties.
Ehlers-Danlos Syndrome and Narcolepsy: An Incidental Relationship?
Authors: Miliken Lindsay , Sedky Karim
Published: May 2019

Ehlers Danlos syndrome (EDS) is a collagenic disease that has often been associated with different types of sleep disorders ranging from insomnia to obstructive sleep apnea (OSA). EDS usually has associated fatigue and excessive daytime sleepiness (ES), thus narcolepsy should be excluded as a cause. Literature review suggests a high prevalence of hypersomnia disorders in this population. We present two sporadic cases presenting with typical symptoms of narcolepsy.

Big data is pushing astronomy in a new direction. Massive amounts of astronomical big data produced by the new generations of powerful instruments and simulations are exponentially gathered every day. Big data like astronomical images, infrared, microwave, ultraviolet, X-rays and gamma generated by stars, galaxies and black holes are observed by the new generations of space telescopes. It may take years to uncover the hidden signals in such data that may already hold answers to some of the fundamental questions of the universe weâ€™re seeking. In this paper, we attempt to present a short review about the astronomical big data and how can such massive data change our understanding of the universe.Â
A Gondwana pre-break up related magmatism in Bafoussam area, west Cameroon: source characteristics and 40Ar/39Ar geochronology

Published: May 2019

The Gondwana pre-break up related formations in Bafoussam area are transitional calc-alkaline doleritic dykes exhibiting high Alumina and low Ti-Mg contents. Their REE compositions are similar to those of E-MORB (Nd/Nb≈1, Zr/Nb≤20). A high partial melting of about 20% of Garnet peridotites source having primitive mantle composition, is inferred to the studied rocks. They are slightly evolved 50<Mg#<54, and its clinopyroxenes are augite of high temperature (600°C-1100°C). The studied dykes were emplaced in a within-plate tectonic setting and yield a 40Ar-39Ar plateau ages of 229±7Ma. These ages are slightly different from those of dolerites from the Oban-Obudu massif (Nigeria), from the basaltic dyke of the Cameroon Volcanic Line and from the Karoo-Ferrar mafic magmatism, all interpreted as magmatism that preceded the break-up of Gondwana. The emplacement age of 229±7Ma of dolerites from Bafoussam area relates them to the very early stage of Gondwana pre-break up magmatism in central Africa.
Trace elements characterisation in floodplain soils underlain by crystalline rocks, akure, southwestern Nigeria
Authors: I.T Asowata , O.G Omokolade
Published: May 2019

The results of the floodplain soils study on the spatial distribution of selected trace elements in top soils (0 – 30 cm) and sub soils (> 30 – 100 cm) near Ala River, Akure metropolis, are reported. The objectives of this study are to determine the concentration of trace elements in the top and bottom soils, and identify the possible enrichment sources of these elements in the floodplain area. Forty two samples (top soil 21; sub soil 21) were collected for the study. The samples were air dried at room temperature, disaggregated and sieved using 53 µg mesh size. The prepared samples were further digested using modified aqua regia of (1:1:1 HNO3: HCL: H2O). The digests were subjected to elemental analysis using Inductively Coupled Plasma-Emission Spectrometry (ICP-MS). The trace elements concentration in ppm exhibited the following distribution pattern. Cu range in ppm from 6.0 – 53.0 mean 27.43; Pb, 10.0 – 165.0, mean 58.43; Zn, 29.0 – 479.0 mean 223.1; Ni, 10.0 – 20.0, mean 14.86; Co, 16.0 – 33.0, mean 24.29; Mn, 250.0 – 1615.0, mean 983.29; Th 9.0 – 19.0, mean 14.43; V, 35.0 – 89.0, mean 73.05; La 26.0 – 84.0, mean 56.76 and Cr 11.0 – 60.0 mean 40.43. While the result for the sub soils range in ppm, Cu from 3.0 – 51.0, mean 21.24; Pb, 7.0 – 208.0, mean 56.33; Zn, 21.0 - 460.0. mean 149.14; Ni, 8.0 – 29.0, mean 13.76; Co, 12.0 – 37.0, mean 23.95; Mn, 138.0 – 2283.0, mean 806.43; Th 9.0 – 28.0, mean 17.48; V, 40.0 – 105.0, mean 68.71; La 25.0 – 96.0, mean 61.00 and Cr 12.0 – 58.0 mean 35.38. The results of both the top soils and sub soils showed higher concentration metal enrichment than the average shale values. The relative elemental mean concentration is such that Mn> Zn > V > La > Pb > Cr > Co > Cu > Th > Ni in that order. Elements such as Cu, Zn, Pb, V, Mn, Th and Cr had relatively moderate to very strong correlation coefficient (r = 0.54 0.97) with each other, which apparently indicate that these elements are of same source of enrichment in the floodplain. Pb, Zn, V, La, Th and Cr are elements that are of significant environmental concerns.

Published: May 2019

Most of the diseases in humans are as a result of complex interactions occurring at cellular and molecular level. Research today has been focused in an attempt to reveal precisely the cellular evolution into pathogenesis. There are vast array of research fields, which include molecular biology, imaging techniques, etc. One of such field recently advancing worldwide is â€œOrganotypingâ€. It is the successor of two dimensional cell cultures. Miniature organs and disease models can be produced from cells having the ability to proliferate and differentiate, by adopting definite protocols. Organoids are the potential tools to probe human biology and diseases; thereby they may change the approach to study diseases and provide treatment, in a more beneficiary way to the patient. Also organoids are used in vaccine production, cancer research, microbiology, tissue regeneration, drug testing, etc. Clinical trials are more devastating and may cost life of patients included in study. As such, organoids can be included in the protocols of clinical trials, through which the outcome of the study can be estimated. They open the doors for newer research methods and innovations, which are in peak requirement of present day scenario where new diseases are emerging and the diseases already existing are not yet cured.Â Â Â

Published: May 2019

The main goal of vital pulp therapy is to preserve and maintain pulpal health in teeth that have been exposed to caries, trauma, and restorative procedures. This type of endodontic treatment is very important in young permanent teeth that have not reached their complete length and exhibit thin-walled roots and wide open apices. The developments in knowledge of pulpal physiology and immunology, beside to newly introduced dental materials, have changed the treatment approaches for teeth with involved pulps. This report describes a case of a young patient in whom maxillary right central incisor suffered crown fractures because of a traumatic accident. Pulpotomy with MTA were performed in order to achieve apexogenesis and the tooth was restored with a glass ionomer cement and composite resin. The patient was reviewed over 4years.Â
Exposición del activo más valioso de la organización, la “información”

A fin de mantenerse activas las organizaciones deben contar con tecnología de punta que facilite su identificación en un mundo globalizado; la forma más fácil, sencilla y económica es haciendo uso de la red de redes. Es aquí donde comienza el trabajo más complicado y al que los administrativos poco valor le dan y mucho menos invierten: dotar de seguridad el activo más valioso de cualquier Institución: la Información. El presente artículo reflexiona sobre los riesgos a los que se expone la información si no se surten las mínimas normas de seguridad: manejo, manipulación, cuidado y asistencia, entre otras. Se resalta que las organizaciones y usuarios tienen la oportunidad de desarrollar de forma fácil actividades desde cualquier lugar, siempre que se tenga en cuenta la cultura de la capacitación y se cuente con planes de respuesta a incidentes, de manera que ellas puedan seguir prestando sus servicios, inclusive si no se tiene el control de la funcionalidad de internet.
Identificación del patrón cinemático del gesto deportivo de percusión en jugadores de rugby
Authors: Torres Pérez Yolanda , Ortega Mogollón Harold Rodrigo
Published: May 2019

En el juego del Rugby, la percusión es una jugada fundamental para la ruptura de la línea de defensa del equipo contrario y así poder llegar a la meta y anotar puntos. Sin embargo, esta jugada no siempre se realiza de forma eficiente biomecánicamente hablando, lo que genera pérdidas del balón y desventaja en el juego. Por lo anterior, se estudió y evaluó el patrón cinemático del gesto técnico-deportivo de jugadores del equipo de Rugby de la Universidad Santo Tomás Seccional Tunja (Boyacá - Colombia), mediante la técnica de videometría, con el objetivo de determinar (cualitativa y cuantitativamente) las trayectorias, ángulos críticos y curvas cinemáticas articulares de los deportistas ejecutando rutinas de percusión, con lo cual se diseñaron e implementaron intervenciones correctivas del movimiento de los deportistas en el descenso del eje de contacto para generar una percusión más eficiente y ergonómica durante el juego.
Análisis de resolución en imágenes de fotoelasticidad: caso carga dinámica
Authors: Briñez de León Juan C. , Fandiño Toro Hermes A. , Restrepo Martínez Alejandro , Branch Bedoya John W.
Published: May 2019

En imágenes de fotoelasticidad, los patrones de franjas envuelven el campo de esfuerzos de un cuerpo birrefringente bajo cargas mecánicas. En estos casos, zonas con concentraciones de esfuerzos producen altas densidades de franjas, dificultando la recuperación, y en ocasiones la pérdida, de la información envuelta en la imagen. Este artículo evalúa el crecimiento de tales regiones y su efecto en el campo de esfuerzos para un caso donde el cuerpo es sometido a cargas dinámicas. Aquí, una secuencia sintética de imágenes de fotoelasticidad es generada partiendo del modelo analítico de la distribución de esfuerzos en un disco bajo compresión diametral. El tamaño de las regiones con pérdida de información es estimado mediante la implementación de transformadas de Fourier y filtros paso alto. Los resultados muestran que el incremento de la carga introduce aumentos en las regiones con pérdida de información. En estos casos, los esfuerzos máximos recuperados a partir de las imágenes se alejan de los valores en el modelo analítico. Esto permite identificar regiones en las imágenes de fotoelasticidad, donde el campo de esfuerzos debe ser corregido
Eficiencia de sistemas multiantena MU–MIMO por simulaciones de radiopropagación
Authors: Arévalo Peña Javier Enrique
Published: May 2019

El presente artículo tiene como propósito realizar la descripción de los resultados de simulación de radiopropagación con una antena MU{MIMO (4x4) en una red LTE (del inglés Long Term Evolution), con el fin de establecer su eciencia respecto a una antena estándar. En esta vía, se emplea la herramienta de diseño de redes inalámbricas ICS Designer en la cartografía digital de alta resolución en un escenario urbano de la ciudad de Bogotá D.C., Colombia. Se utiliza el modelo 3GPP LTE en la simulación de la red LTE y se analizan los parametros RSRP (del inglés, Reference Signal Received Power), RSRQ (del inglés, Reference Signal Recieved Quality), SNIR (del inglés, Signal to Noise and Interference Ratio) rendimiento (Throughput) y QCI (del inglés, QoS Class Identier). Se evidencian, como consecuencia de los resultados, ventajas de las antenas MU-MIMO.
Análisis Político de Discurso: Herramientas conceptuales y analíticas para el estudio crítico de políticas educativas en tiempos de reforma global
Authors: Palacios Díaz Diego , Hidalgo Kawada Felipe , Cornejo Chávez Rodrigo , Suárez Monzón Noemí
Published: May 2019

En el contexto de un movimiento global de reformas educativas, los principios y políticas de la Nueva Gestión Pública (NGP) se han tornado hegemónicos para direccionar el cambio educativo en distintos países del orbe. Pese a los cuestionamientos recibidos, existe la percepción generalizada de que los programas de NGP son los más idóneos para resolver los problemas que apremian a los sistemas educativos contemporáneos, lo cual explica la masiva adopción de sus lineamientos en distintos contextos. Reconociendo que los aspectos discursivos e ideacionales juegan un papel relevante en dicho posicionamiento, en este artículo ofrecemos un set de herramientas conceptuales y analíticas para leer críticamente políticas educativas en tiempos de reforma global. Para cumplir dicho propósito examinamos el enfoque de Análisis Crítico de Discurso (ACD) de Norman Fairclough y lo vinculamos con el Análisis Político de Discurso (APD), modelo analítico complementario al ACD que releva las especificidades del género de política pública. Posteriormente, y mediante un ejercicio analítico, desplegamos una secuencia metodológica – práctica que posibilita estudiar críticamente textos y discursos de política educativa. Finalmente, valoramos las herramientas presentadas y enfatizamos en la necesidad de integrar lógicas denunciantes – anunciantes en el estudio críticamente orientado de los aspectos discursivos de la política educativa.
Roman som skuespill: Sjangerhybriditet i Erlend Loes Stille dager i Mixing Part
Authors: Humpál Martin
Published: May 2019

Erlend Loe’s novel Stille dager i Mixing Part (2009, Quiet Days in Mixing Part) focuses on a marital crisis of a Norwegian couple on vacation in Germany. The husband, Bror Telemann, is a dramaturg who dreams of writing a major play, and he tries in vain to begin to write one. The novel is a third-person narrative, but it actually contains few narrative passages: most of the text consists of dialogues. The text is, in fact, a hybrid of two genres – part novel, part play. This seems to be a consciously chosen aesthetic strategy on Loe’s part. The main thematic aspects of Stille dager i Mixing Part are tied up with drama and theatre in various ways. This article shows how genre hybridity, aided by intertextual allusions, contributes to representing these main aspects.
Narrative Complexity and Cultural Relevance in the Name of Public Service Broadcasting: The Cases of Borgen and Herrens Veje
Authors: Hochscherf Tobias
Published: May 2019

Danish television has been able to produce a remarkable number of successful primetime dramas over the last years from Forbrydelsen (The Killing, DR 2007-12) to Herrens Veje (Ride upon the Storm, DR 2017-). Many of them are Nordic Noir crime dramas, yet the list also includes political thrillers and family dramas. This article briefly summarizes main reasons for the prolific production environment at public service broadcaster Danmarks Radio (DR). Some of the exceptional circumstances of Danish television demonstrate why the relatively small country was able to produce shows that found devoted audiences around the world. While the DR production framework has received much attention, this article takes a closer look at narrative composition, issues of characterization and the presentation of themes. Analyzing the first episodes of Borgen (DR 2010-13) and Herrens Veje, the article proposes that it is specifically the combination of multiperspectivity of the leading protagonists and how their life is linked to wider cultural, social and political debates, that can be identified as one main outcome of the fruitful collaboration between DR and various creative personnel. While both shows adhere to the main characteristics of complex serial drama as identified by Jason Mittel and Trisha Dunleavy, there are also some noticeable differences, including their strong public service ethos, their unusual Danish settings, the avoidance of transgressive protagonists, character-centred storylines and their slow, indulgent pace.
Not All Entrepreneurs are Viewed Equally: A Social Dominance Theory Perspective on Access to Capital
Authors: Gutierrez Angelica S. , D’Mello Jason Francis
Published: May 2019

Drawing on social dominance theory, the present research examines how the characteristics of a potential investor – namely, social dominance orientation (SDO) (i.e. the degree to which individuals seek to maintain inequality between groups) interacts with the characteristics of the entrepreneur (i.e. race) to influence capital decision-making. Study 1 found that as a function of individuals’ SDO, individuals supported a policy that would increase funding access to White but not minority entrepreneurs. Study 2 found that as a function of SDO, individuals were willing to invest in White but not minority-owned firms. The perceived threat of the entrepreneur’s success to the extant racial hierarchy explained differences in investment decisions. The present research in the field of entrepreneurship is the first to apply Social Dominance Theory and Social Dominance Orientation (Sidanius, J., and F. Pratto. 1999. Social Dominance: An Intergroup Theory of Social Hierarchy and Oppression. New York: Cambridge University Press.), which have received much attention in social psychology and organizational behavior, to funding access and investment decisions. In doing so, these studies answer the call by (Klotz, A. C., and D. O. Neubaum. 2016. “Research on the Dark Side of Personality Traits in Entrepreneurship: Observations from an Organizational Behavior Perspective.” Entrepreneurship Theory and Practice 40 (1): 7–17.) to examine the relationship between “darker” personality traits, such as SDO, and entrepreneurial outcomes.
Inclusory pronouns in Mande: The emergence of a typological rarum
Authors: Khachaturyan Maria
Published: May 2019

This paper reviews inclusory constructions and pronouns in the Mande language family and proposes a diachronic account of their development. Inclusory constructions, which are found in several Mande languages, are a type of conjunction strategy where the whole set of participants – the superset – and a subset of participants are expressed, as in Dan-Gwetaayāā Gbȁtȍ‘Gbato and I’, lit. ‘we Gbato’. In a number of Southern and Southwestern Mande languages, inclusory constructions are typologically unique, as they feature a separate series of inclusory pronouns, which are used exclusively in this construction. The paper argues that these inclusory pronouns are a Southwestern Mande innovation, which spread to other Mande languages through contact.
Variation in the acoustic correlates of emphasis in Jordanian Arabic: Gender and social class
Authors: Omari Osama , Jaber Aziz
Published: May 2019

The present study investigates the effect of gender and social class on the acoustic correlates of emphasis in Jordanian Arabic. To achieve this goal, 40 participants were recorded reading a list of minimal pairs, and several acoustic measurements were taken, including VOT (voiceless stops), post-release duration (voiced stops), friction duration, vowel duration, and vowel formant frequencies (F1–F3) at onset and midpoint positions.

The results of the study reveal that significant gender and social class differences in emphasis production have different linguistic distributions. Gender differences were relevant at F1 and F2 at the onset and midpoint, whereas social class differences were evident at the onset position of F1 and F2, vowel duration, and the post-release duration of the voiced emphatic stop. Generally, male speakers produced stronger cues of emphasis, the non-prestigious form, than female speakers, as they made more F1 raising and F2 lowering in the emphatic environment. Strong emphasis cues were also favored by the lower-middle class speakers.

The results also showed that the effect of gender significantly intersects with that of social class. At F1(onset and midpoint), significant gender differences existed only within the upper-class group. At F2 midpoint, however, gender differences were evident only in the lower-middle class group.
Article-like constructions and the definite-indefinite continuum in Croatian
Authors: Belaj Branimir , Matovac Darko , Faletar Goran Tanacković
Published: May 2019

The first goal of this paper is to give a description of the article-like uses of the Croatian numeraljedan‘one’, the indefinite determinerneki‘some’ and the demonstrative determinertaj‘this’ within the theoretical framework of Cognitive Grammar. This description places these constructions along a cognitively grounded definiteness hierarchy spanning from the demonstrative determinertaj(definite) on one side tojedan(indefinite specific) andneki(indefinite non-specific) on the other side. The second goal of the paper is to give a description of the constructions combining the article-like demonstrative determinertajwith the article-like numeraljedanand the article-like indefinite determinerneki, i.e.taj jedanandtaj neki, lit. ‘this some/this one’. The functions and usage profiles of these constructions are carefully differentiated and, in order to explain the data obtained, a richer articulation of the cognitively grounded definiteness hierarchy is put forth. A new position is proposed, existing between definiteness and specific indefiniteness, to account for entities that are contextually defined as indefinite bytaj jedanandtaj neki.
Language surveillance: Pressure to follow local models of speakerhood among Latinx students in Madrid
Authors: Martín Rojo Luisa , Márquez Reiter Rosina
Published: May 2019

In this article, we examine the language surveillance – both self and externally imposed – experienced by Madrid university students of Latin American origin in their encounters with the local population in educational settings. A pattern of language surveillance emerges in the interviews held with these students. It consists of hierarchical observation, normalising judgment and interrogation. These three reported practices are related to the following linguistic and non-linguistic resources that make surveillance possible, namely: (a) indexicality, especially with regard to phonological distinctions that index speakers as “local” vs. “non-local” or “native” vs. “non-native”; (b) the invoking of disciplinary and prescriptive linguistic knowledge, together with the application of a colonial episteme whereby the metropolitan norm prevails, thus denying non-metropolitan speakers their right to language ownership; and, (c) the management of power within interactions. By these means, varieties and speakers of Spanish are hierarchised and those that differ from locals are positioned as subaltern others. Language surveillance is a disciplinary power technique that prompts speakers to adapt to the centripetal force exerted by the reproduction of this knowledge. Finally, the article examines the extent to which this stylistic move to adapt, could be considered an example of muda given that these shifts are situational and relational and attend to the different social demands of the communicative settings where the practice is observed.
