Relative Association of Multi-Level Supportive Environments on Poor Health among Older Adults
Authors: Mier Nelda , Ory Marcia , Towne Samuel , Smith Matthew
Published: April 2017

Background: The aging of the United States population poses significant challenges to American healthcare and informal caregiving systems. Additional research is needed to understand how health promotion programs and policies based on a socio-ecological perspective impact the health and well-being of older persons. The purpose of this study was to investigate personal characteristics and supportive environments associated with poor health among older individuals aged 65 and over. Methods: This study used a cross-sectional design and was guided by a conceptual framework developed by the authors to depict the relationship between personal characteristics and environments associated with poor health status. Environment types included in this study were family, home, financial, neighborhood, and healthcare. The sample was comprised of 1319 adults aged 65 years and older residing in Central Texas. From a random selection of households, participants were administered a mail-based survey created by a community collaborative effort. Descriptive statistics and three binary logistic regression models were fitted to examine associations with poor health status (i.e., physical, mental, and combined physical/mental). Results: Two personal characteristics (number of chronic conditions and educational level) were consistently related (p < 0.05) to health outcomes. Supportive family, home, financial, neighborhood, and health care environmental factors were shown to be related (p < 0.05) to various aspects of physical or mental health outcomes. Conclusions: Multidimensional factors including personal characteristics and protective environments are related to health status among older individuals. The unique roles of each environment can help inform public health interventions to create and enhance support for older adults to engage in healthful activities and improve their physical and mental health.
Sulfated Hetero-Polysaccharides Protect SH-SY5Y Cells from H2O2-Induced Apoptosis by Affecting the PI3K/Akt Signaling Pathway

Published: April 2017

Parkinson’s disease (PD) is one of the most common neurodegenerative diseases. Recent studies suggest that sulfated hetero-polysaccharides (UF) protect against developing PD. However, the detailed mechanisms of how UF suppress neuronal death have not been fully elucidated. We investigated the cytoprotective mechanisms of UF using human dopaminergic neuroblastoma SH-SY5Y cells as a PD model. UF prevented H2O2-induced apoptotic cell death in SH-SY5Y cells in a dose-dependent manner. An examination of the PI3K/Akt upstream pathway revealed that UF-pretreated cells showed a decreased relative density of Akt, PI3K, and TrkA, and increased the phosphorylation of Akt, PI3K, and NGF; the PI3K inhibitor, LY294002, partially prevented this effect. An examination of the PI3K/Akt downstream pathway revealed the increased expression of the apoptosis-associated markers Bax, p53, CytC, and GSK3β, and the decreased expression of Bcl-2 in UF-treated cells. UF-treated cells also exhibited decreased caspase-3, caspase-8, and caspase-9 activities, which induced cell apoptosis. Our results demonstrate that UF affect the PI3K/Akt pathway, as well as downstream signaling. Therefore, the UF-mediated activation of PI3K/Akt could provide a new potential therapeutic strategy for neurodegenerative diseases associated with oxidative injury. These findings contribute to a better understanding of the critical roles of UF in the treatment of PD.
Adsorption of Ten Microcystin Congeners to Common Laboratory-Ware Is Solvent and Surface Dependent
Authors: Altaner Stefan , Puddick Jonathan , Wood Susanna , Dietrich Daniel
Published: April 2017

Cyanobacteria can produce heptapetides called microcystins (MC) which are harmful to humans due to their ability to inhibit cellular protein phosphatases. Quantitation of these toxins can be hampered by their adsorption to common laboratory-ware during sample processing and analysis. Because of their structural diversity (>100 congeners) and different physico-chemical properties, they vary in their adsorption to surfaces. In this study, the adsorption of ten different MC congeners (encompassing non-arginated to doubly-arginated congeners) to common laboratory-ware was assessed using different solvent combinations. Sample handling steps were mimicked with glass and polypropylene pipettes and vials with increasing methanol concentrations at two pH levels, before analysis by liquid chromatography-tandem mass spectrometry. We demonstrated that MC adsorb to polypropylene surfaces irrespective of pH. After eight successive pipet actions using polypropylene tips ca. 20% of the MC were lost to the surface material, which increased to 25%–40% when solutions were acidified. The observed loss was alleviated by changing the methanol (MeOH) concentration in the final solvent. The required MeOH concentration varied depending on which congener was present. Microcystins only adsorbed to glass pipettes (loss up to 30% after eight pipet actions) when in acidified aqueous solutions. The latter appeared largely dependent on the presence of ionizable groups, such as arginine residues.

Appraisal and Coping Responses to Tourism Development-Related Stress
Authors: Jordan Evan J. , Vogt Christine A.
Published: April 2017

Unmitigated stress can lead to a variety of negative health and emotional outcomes, negatively affecting overall quality of life. Individuals' stress appraisal and coping responses to stress influence the extent to which they are affected by stress. This study explores the relationship
between secondary stress appraisal (controllability) and coping responses to tourism-related stressors such as unmet development expectations. A total of 363 pen and paper surveys were administered face-to-face to a systematic random sample of residents of Falmouth, Jamaica—a community
that recently hosted the development of a new Caribbean cruise port. A structural equation model revealed that the appraisal of stress as controllable had a significant positive relationship with problem-focused coping and positive outlook coping responses as well as a significant negative
relationship with less effective wishful thinking coping responses. The appraisal of stress as controllable by someone else had a significant positive relationship with seeking social support coping responses. The appraisal of stress as uncontrollable was significantly negatively related with
wishful thinking coping responses. This study is a first step toward understanding the complex and continually changing process of stress appraisal and coping engaged in by residents of a tourism host community.
Impact of Airline Top Management Teams on Corporate Social Responsibility
Authors: Lee Won Seok , Kim Chulwon , Moon Joonho , Yoon Hyejin
Published: April 2017

The purpose of this article is to examine the determinants of corporate social responsibility (CSR) in the airline industry by applying the conceptual framework of upper echelon theory. Based on this theory, certain attributes of managers—such as age, tenure, formal education level, share ownership, and stock options—are hypothesized to have an impact on CSR decisions. Furthermore, rather than considering only the chief executive officer's characteristics, the entire top management team (TMT) is taken into account to draw more robust conclusions. Data are collected from 13 publicly traded airlines in the US stock market from 1998 to 2013 and analyzed by panel feasible generalized squares. Based on the findings, the TMT's average age and the value of stock options held by the TMT are key in accounting for CSR decisions. The age of the TMT positively affects the airlines' CSR, whereas the value of stock options has a negative impact on CSR.
Visitor Economic Impact Estimates of Garrett County, Maryland
Authors: Deng Jinyang , Gazal Kathryn , Selin Steven
Published: April 2017

It is a major challenge to estimate the total visitation of a destination without gate counts. This study proposes a modified ratio-based approach by which the visitor number and visitor volume at a county level (Garrett County, MD) are estimated using survey information on the sample
percentage of a given visitor type antd the actual documentation of visitor counts of that visitor type. It is estimated that the total person-trips for the county are 1,117,744 during the survey period between August 2008 and July 2009 with an estimated total visitor spending being $243.3
million. Visitor economic impact analyses using IMPLAN indicate that visitors of the county have a total economic impact of $347.7 million in sales. The study shows that the county is quite comparable in terms of the total visitor spending with nearby ski resort counties in West Virginia
and also competitive against most other counties in the state.
Comparison of Models and Whole‐Genome Profiling Approaches for Genomic‐Enabled Prediction of Septoria Tritici Blotch, Stagonospora Nodorum Blotch, and Tan Spot Resistance in Wheat

Published: April 2017

The leaf spotting diseases in wheat that include Septoria tritici blotch (STB) caused byZymoseptoria tritici, Stagonospora nodorum blotch (SNB) caused byParastagonospora nodorum, and tan spot (TS) caused byPyrenophora tritici‐repentispose challenges to breeding programs in selecting for resistance. A promising approach that could enable selection prior to phenotyping is genomic selection that uses genome‐wide markers to estimate breeding values (BVs) for quantitative traits. To evaluate this approach for seedling and/or adult plant resistance (APR) to STB, SNB, and TS, we compared the predictive ability of least‐squares (LS) approach with genomic‐enabled prediction models including genomic best linear unbiased predictor (GBLUP), Bayesian ridge regression (BRR), Bayes A (BA), Bayes B (BB), Bayes Cπ (BC), Bayesian least absolute shrinkage and selection operator (BL), and reproducing kernel Hilbert spaces markers (RKHS‐M), a pedigree‐based model (RKHS‐P) and RKHS markers and pedigree (RKHS‐MP). We observed that LS gave the lowest prediction accuracies and RKHS‐MP, the highest. The genomic‐enabled prediction models and RKHS‐P gave similar accuracies. The increase in accuracy using genomic prediction models over LS was 48%. The mean genomic prediction accuracies were 0.45 for STB (APR), 0.55 for SNB (seedling), 0.66 for TS (seedling) and 0.48 for TS (APR). We also compared markers from two whole‐genome profiling approaches: genotyping by sequencing (GBS) and diversity arrays technology sequencing (DArTseq) for prediction. While, GBS markers performed slightly better than DArTseq, combining markers from the two approaches did not improve accuracies. We conclude that implementing GS in breeding for these diseases would help to achieve higher accuracies and rapid gains from selection.
Aux filles et aux fils des dieux du carnage. Filiations religieuses dans la psychanalyse
Authors: Tort Michel
Published: April 2017

Le rapport que la psychanalyse entretient aux normes et au genre est profondément lié à la religion et aux religions. L’enjeu est de poursuivre l’entreprise de L’avenir d’une illusion en repérant ses butées. On reconstitue d’abord comment les positions religieuses notamment chrétiennes sont l’horizon des débats passionnés sur le genre et les sexualités depuis les années 1970, après les mouvements de 1968. Certains psychanalystes ont tendance depuis à faire dériver leurs discours et leurs pratiques de ces positions religieuses traditionnelles. Des notions psychanalytiques données pour fondamentales, comme la « fonction paternelle », sont solidaires de cette dérive et traduisent l’intrusion dans la psychanalyse du patriarcat religieux. On montre les difficultés des psychanalystes à sortir de leurs histoires avec leurs religions. On examine enfin la consistance du modèle freudien de la maladie religieuse issu de L’avenir d’une illusion en l’appliquant à la « maladie chrétienne » dont on fait ressortir les ravages historiques redoutables, à un moment où d’autres religions lui font concurrence.
Le pouvoir de l’autonomination. Sur la loi argentine d’identité de genre
Authors: Rosenberg Martha I
Published: April 2017

L’assignation de sexe initiale et la réassignation de genre autoperçu sont-elles tributaires d’une conception essentialiste de la sexuation ? Ont-elles en partage l’idée qu’à une position sexuée au sein du binarisme conventionnel correspond une morphologie anatomique déterminée ? Procèdent-elles à un diagnostic de normalité ou de pathologie en lisant l’apparence des organes génitaux externes à partir d’un appareil idéologique de réduction de la sexualité à une finalité reproductive ? Le traitement d’adéquation de l’image au vécu n’indique-t-il pas que la correspondance entre ces deux instances « normalise » et confère ainsi une intelligibilité aux corps humains qui ne correspondent pas aux modèles ?
La représentation qui rend fou… Psychopathologie du processus représentatif dans les états psychotiques
Authors: Di Rocco Vincent
Published: April 2017

Cet article s’appuie sur l’hypothèse qu’une représentation peut paradoxalement confronter l’appareil psychique à l’irreprésentable, l’irreprésentable n’étant pas lié directement à la nature du vécu à représenter, mais à ce qui apparaît comme un échec du travail de transformation des processus psychiques. Cette confrontation à l’irreprésentable mobilise la psyché selon deux registres : d’une part, les différents registres de l’expression symptomatique peuvent être compris comme une tentative de représenter le vécu qui reste insaisissable, et d’autre part, dans le cadre psychothérapique, les modalités d’expression du sujet représentent une tentative de figurer le processus psychique en échec. Deux exemples cliniques illustrent ces logiques.
L’ acting-out de parole, vers un dire possible sur la maltraitance en gériatrie
Authors: Guibert Émile
Published: April 2017

Dans un contexte de maltraitance par négligence en gériatrie, il est apparu qu’avec l’instauration d’un espace de parole un véritable renversement s’opérait, modifiant les coordonnées du passage à l’acte répété et permettant au soignant de s’inscrire dans un autre type d’agir, en dehors de cet espace de parole. Les coordonnées de celui-ci, analogue à celle décrite dans l’acting-out, s’opposent en quelque sorte point par point à celles du passage à l’acte, authentique laisser-tomber institutionnel envers l’idéal et la parole des soignants. L’instauration de cet espace de parole permet au soignant de reporter une expérience de la répétition à l’œuvre institutionnellement, de la rendre actuelle dans le transfert, et établit également la potentialité d’un dire sur la maltraitance. L’acting-out est ainsi apparu dans cette recherche en tant que possibilité clinique : à la condition de l’instauration de cet espace de parole, la répétition de la maltraitance peut se rejouer à travers une forme d’agir analogue à l’acting-out. En somme, il existe une modalité spécifique d’agir en dehors de cet espace, révélant de ce fait toutes ses possibilités cliniques en termes d’élaboration, de parole possible sur la maltraitance, de travail sur l’angoisse et le transfert (que l’acting-out tente de méconnaître) dans ces liens avec la résistance à la parole manifestée par les soignants durant nos rencontres cliniques.
25 ans de politique extérieure turque : la quête de sens stratégique
Authors: Billion Didier
Published: April 2017

La Turquie est indéniablement l’un des pays qui s’est affirmé dans la région au cours des vingt-cinq dernières années. Poursuivant la longue quête d’identité qui caractérise l’élaboration de sa politique extérieure, différentes séquences se sont succédées sans pour autant jamais remettre en cause la sourcilleuse détermination d’Ankara de toujours préserver son indépendance et sa souveraineté nationales et d’utiliser la rente stratégique procurée par sa situation géopolitique. Les évolutions observées ne semblent pas remettre en cause ces fondamentaux.
Penser la psychanalyse avec la psychose
Authors: Fierens Christian
Published: April 2017

Chez Freud et chez Lacan, la psychose a toujours servi à relancer la pensée, non sans conséquences pour la psychanalyse. Cependant, la psychose témoigne d’une antinomie entre la pensée et la réalité . Chez Freud, la psychose sert d’introduction pour la pensée du développement du moi (narcissisme), à entendre non pas comme une fonction imaginaire, mais comme le développement de la structure toujours à refaire et à reprendre (dans le cours de l’analyse en général). Chez Lacan, la psychose sert d’introduction pour la nécessité de penser la question du sujet et celle-ci s’explicitera dans une topologie mœbienne et une topologie borroméenne. Cette mobilisation de la pensée par la prise en considération de la psychose remet en question tout à la fois la réalité, la perception, le sujet, en même temps qu’elle incite à développer le champ proprement psychanalytique de la réalité psychique, de l’hallucination et de l’objet a .
Quelques considérations à propos de la notion de « métaphore délirante »
Authors: Pellion Frédéric
Published: April 2017

L’article examine la question de savoir si la manière dont Lacan pose et développe la notion de « métaphore délirante » ne contient pas déjà bon nombre des ingrédients ultérieurement réarrangés par le Lacan borroméen. Cela conduit à nuancer la supposée rupture borroméenne, en particulier en ce qui concerne notre conception de la psychose.
De l’accouchement à la mise au monde humain des enfants dans les sociétés traditionnelles
Authors: Barry Aboubacar
Published: April 2017

Dans les conceptions traditionnelles de la procréation chez les humains, la participation du père est niée ou fortement relativisée. Aux îles Trobriand par exemple, on explique que le père n’est pas le géniteur de ses enfants, mais que ceux-ci sont des esprits d’ancêtres de la mère qui s’introduisent en elle par ses flancs, ce qui a conduit aux formulations bien connues et très étranges de Bronislaw Malinowski. En Afrique, beaucoup d’ethnies pensent que seule l’intervention favorable d’un petit génie de la brousse permet au père de féconder sa femme ; l’enfant est aussi censé être une réincarnation d’un ancêtre. Ces représentations traditionnelles de la conception de l’enfant humain sont examinées à partir des théories psychanalytiques, surtout freudiennes et lacaniennes, de la représentation de la naissance des enfants dans les théories infantiles et de la notion de Nom-du-Père.
Le propre de la femme ? Le rire de Sarah et de Déméter
Authors: Schaeffer Jacqueline
Published: April 2017

Résumé De qui, de quoi, pourquoi et comment les femmes rient-elles ? Le rire serait inconvenant dans la bouche d’une femme. La honte anale vise le lâchage du contrôle. La honte sexuelle joint la décharge du rire à la décharge orgastique, et l’exhibition du rire rejoint l’exhibition du sexe féminin. Le rire est défensif contre l’angoisse de castration, et il peut lui-même être castrateur face au phallique des hommes. L’homosexualité du rire des femmes est libérateur. De même que le rire peut avoir une vertu exorciste face à la peur, et consolatrice et anti-traumatique face à la souffrance et à la perte.
Transformations de la jubilation : le devenir du rire chez un enfant souffrant de troubles autistiques
Authors: Reignier Sylvie
Published: April 2017

Résumé Le jeu de miroir affecté qui peut, parfois, se déployer dans certaines séquences imitatives avec l’enfant autiste, est susceptible déclencher des moments de jubilation rares et intenses. Les traces représentatives de cette expérience de satisfaction sont parfois bien difficiles à retrouver, en raison de la difficulté de l’enfant autiste à se situer dans une répétition suivant le principe de plaisir des situations vécues avec l’objet. Cependant il reste « quelque chose » : une répétition transformée, souvent réifiée, mais témoin d’un maillage pulsionnel initial, premier niveau d’intrication pulsionnel, qui permet une mise en forme d’un sadisme primaire devenu supportable pour le psychisme de l’enfant.
Larmes du rire
Authors: Servant Benoît
Published: April 2017

Résumé L’auteur s’intéresse à une forme particulière du rire, « arme » pour se défendre contre l’empêchement de penser. Il l’illustre à partir de l’usage politique de l’humour dans les pays totalitaires, un roman de David Grossman, trois vignettes cliniques, et la réflexion de J-L Donnet sur l’humour dans la cure. Il développe l’hypothèse selon laquelle derrière l’arme du rire, il y aurait les larmes de l’enfant déçu par l’adulte qui ne l’a pas introduit au monde humain, et l’espoir de trouver enfin ce dont il a été cruellement privé.
La « douce science » des coups
Authors: Beauchez Jérôme
Published: April 2017

La boxe, ou la « douce science » des coups («  sweet science  » en anglais), est loin de représenter un sujet mineur pour les sociologues et les ethnographes. De plus en plus nombreux, leurs travaux constituent autant d’analyses où s’affrontent non seulement des corps, mais aussi différentes conceptions de l’enquête et du rapport des chercheurs à leurs terrains. En les parcourant un à un, cet article retrace l’histoire d’un objet sociologique dont les contours restaient à définir. Il montre que, au-delà de leurs différences, les manières de comprendre ou d’expliquer la condition de boxeur sont toutes traversées par une question centrale : celle de la domination. Tandis qu’elle est au principe des combats livrés sur le ring, les chercheurs en perçoivent les expressions à l’intersection du « genre », de la « classe » et de la « race ». Aussi ne manquent-ils pas de voir, dans les scènes pugilistiques, diverses représentations des luttes que livrent les subalternes contre les forces d’exclusion tendant à les maintenir dans des positions socialement dominées.
Challenges in Neonatal Nursing Clinical Teaching to Nurse-Midwife Technicians in Malawi
Authors: Phuma-Ngaiyaye Ellemes Everret , Adejumo Oluyinka , Dartey Anita Fafa
Published: April 2017

Background:

Practice-based learning is important in clinical teaching of nursing and midwifery as students develop the necessary competencies and confidence aligned by the outcomes of their learning programs. However, in Malawi, research shows that clinical teaching in neonatal nursing has not been given adequate consideration. This article reports on challenges faced by educators and students in clinical teaching and learning in neonatal nursing for nurse-midwife technicians.

Method:

An explorative qualitative study was conducted. Data were collected through 23 focus group discussions with 140 students and 31 clinical teachers from eight nursing colleges. Audiorecorded data were transcribed verbatim and analyzed using Hennink's content analysis stages.

Results:

Challenges faced by clinical teachers and students were short duration and variation in clinical placements, lack of emphasis in clinical teaching, and lack of skills among clinical staff.

Conclusion:

Nursing training institutions should maximize student learning opportunities in neonatal nursing practice by creating more practice-based learning opportunities that meet the students' needs. [

Using Quantitative Literacy to Enhance Critical Thinking Skills in Undergraduate Nursing Students
Authors: Asknes Edna
Published: April 2017

Background:

Critical thinking and quantitative literacy (QL) are similarly grounded: both focus on analyzing and evaluating evidence, identifying implications and consequences, drawing inferences, and communicating information. This teaching strategy was based on those commonalities and was designed so that undergraduate nursing students would enhance their critical thinking skills as they used their QL skills.

Method:

QL skills are most effective when taught, learned, and used to solve significant, pertinent problems. Using the principles of learner-centered, team-based learning, QL was integrated into the curriculum of the Maternal–Newborn Nursing course at an urban community college with a diverse student population.

Results:

Students were engaged and demonstrated enhanced and ongoing development of their critical thinking and problem-solving skills. They also reported a better understanding of data interpretation and use.

Conclusion:

The positive outcome of this project revealed further opportunities for incorporating QL into nursing curricula and highlighted the need for research on the use of QL in nursing education. [

Arquitectura e ingeniería en Alcoy. 90 años del puente de San Jorge
Authors: Picó Silvestre J. F.
Published: April 2017

A finales del año 1925 se comenzó en Alcoy la construcción del puente de San Jorge. Se trata de uno de los primeros viaductos de grandes dimensiones construido enteramente en hormigón armado visto de España, pero además constituye uno de los únicos ejemplos contundentes que utilizó el lenguaje formal Art Déco en sus elementos. El 90 aniversario de esta construcción debe servir para conmemorar el éxito de una estrecha colaboración entre ingeniería y arquitectura. Este puente tuvo peculiares problemas y modificaciones importantes durante la construcción que fueron resueltos satisfactoriamente en un momento de la historia en el que la cultura se dirigía hacia la modernidad. En el caso que nos ocupa, el oficio del ingeniero y del arquitecto, oportunamente elegidos por una empresa constructora sagaz y efectiva en sus habilidades constructoras, dio como resultado una magnífica obra olvidada que conviene rehabilitar en la memoria colectiva.
La République et ses autres
Authors: Mazouz Sarah
Published: April 2017

La France a-t-elle peur de ses autres ? En revenant sur les discours et les pratiques qui se formalisent depuis une quinzaine d’années, Sarah Mazouz interroge les « politiques françaises de l’altérité ». À partir d’une double enquête ethnographique conduite dans les dispositifs de lutte contre les discriminations raciales et dans les bureaux de naturalisation d’une grande ville de la région parisienne, elle montre comment s’articulent dans l’espace social les questions de l’immigration, de la nation et de la racialisation. En faisant porter l’examen de manière originale sur ces deux politiques, elle interroge les processus d’inclusion et d’exclusion à l’intérieur même du groupe national (via l’examen de la lutte contre les discriminations raciales) et à l’extérieur, entre le national et étranger (via l’étude des pratiques de naturalisation). Ce faisant, elle s’attache à saisir la relation paradoxale qui lie la République à ses autres et les logiques plurielles qui concourent à la production de l’ordre national.
An Extensive Unprovoked Left Lower Extremity Deep Vein Thrombosis Secondary to an Anatomical Anomaly: A Case of May-Thurner Syndrome
Authors: Ahsan Irfan , Qureshi Binish G. , Ghani Ali Raza , Malik Faizan , Arif Zulfiqar
Published: April 2017

May-Thurner syndrome (MTS) also known as Cockett’s syndrome is a rare condition responsible for 2%-3% of all cases of deep venous thrombosis (DVT). The thrombosis results from mechanical compression of the left common iliac vein against the body of the fifth lumbar vertebra by the right common iliac artery. Repetitive hyperplasia of the venous wall by compression results in spur formation that in turn causes venous flow obstruction and results in the DVT. Our case is a young female who had acute extensive proximal DVT due to MTS that was successfully managed using mechanical thrombectomy with a venous stent. MTS although a rare entity should be suspected especially in young patients with unilateral DVT with extensive clots especially on left lower extremity without any antecedent risk factors.
La retórica del titular deportivo
Authors: Suárez-Ramírez Sergio , Suárez-Muñoz Ángel
Published: April 2017

El titular periodístico es clave para llamar la atención sobre una noticia. Hoy día lo es aún más. El ciberperiodismo, periodismo en internet, pese a competir con miles de reclamos informativos y publicitarios, es un espacio donde `llamar la atención´ ha llegado a ser una necesidad; en este ámbito, el titular periodístico debe ser lo suficientemente atractivo y sugerente para `retener´ la atención del lector. Por otro, nos encontramos en el momento presente con un nuevo lector. Un lector que diversifica sus intereses, que pide concreción, que agradece síntesis en las noticias para poder atender otras ocupaciones lectoras. Aquí el titular adquiere una relevancia especial, porque en muchos casos llega a ser `la noticia completa´, al menos la que lee ese lector súper ocupado. A todo esto hay que añadir el interés que suscita la prensa deportiva. Mientras que el deporte es hoy un fenómeno social, se ha desarrollado una comunicación especializada: la comunicación deportiva. Para algunos autores el deporte es en una fuente inagotable de noticias; para otros, es la actividad que mayor volumen de información genera. En definitiva, el deporte es en la actualidad uno de los temas de más éxito para la audiencia. Prueba de ello es que el periódico que más se lee en España es un periódico especializado en el ámbito deportivo (Marca). Abordamos en este artículo la retórica que emplea el ciberperiodismo deportivo a través del titular periodístico y que profundiza en todos estos aspectos.
Museo y comunicación 2.0. Situación en España
Authors: Jiménez-Orellana Luis Jesús
Published: April 2017

Se analiza cómo la difusión de los museos españoles ha evolucionado con la aparición de las tecnologías de la comunicación y la información (TICs), generando nuevos vínculos comunicativos y situando al visitante en el eje central de los mismos. Se valora la función de difusión de diferentes medios (Twitter, Facebook, Instagram, Flickr, Pinterest, Tumblr, las páginas web, blogs, visitas virtuales, las apps, juegos para tablets y smartphones, códigos QR, Vimeo, YouTube, Google, Foursquare y Periscope) y su aplicación concreta por el Museo Thyssen–Bornemisza de Madrid, a modo de ejemplo, por ser uno de los centros más avanzados en el uso de estas redes sociales. Se demuestra que estas redes resultan ya imprescindibles para acercar los contenidos de los museos a la sociedad, pero que exige un nuevo planteamiento de la comunicación en sentido horizontal y un trabajo continuo de actualización.
Fondos documentales de la Academia de las Artes y las Ciencias cinematográficas de España. Los Premios Goya (1987-2016)
Authors: Corrales-Muñoz Alba
Published: April 2017

Se examinan los fondos documentales de la Biblioteca y Archivo de la Academia de las Artes y las Ciencias Cinematográficas de España, relacionados con las películas ganadoras en la categoría Mejor Película de los Premios Goya, que en 2016 cumplen 30 años. El objetivo del estudio es valorar, por una parte, la importancia y relevancia de esta documentación en el conocimiento de la historia del cine español y, por otra, su difusión y accesibilidad. El análisis se basa en el estudio de los documentos conservados y en entrevistas a los responsables del departamento. Se tienen en cuenta cuestiones como la creación del archivo, la procedencia y características de los fondos conservados, el tratamiento y catalogación de los mismos, y la difusión que reciben. Se concluye que la Academia de Cine custodia un fondo documental indispensable para investigar la historia del cine español, pero que dicho fondo necesita una estrategia de dinamización para logar una mayor difusión y accesibilidad, todo ello posible si se lleva a cabo su integración en el portal Europeana.
Valorización de archivos personales musicales mediante el sistema de catalogación relacional multidireccional: el ejemplo del archivo Mantecón
Authors: Prieto Laura
Published: April 2017

La presentación del archivo completo del compositor Juan José Mantecón, tanto en la idiosincrasia que le es única e intransferible, como en virtud de su pertenencia a esa categoría que denominamos archivos personales musicales, aborda unas líneas de actuación que profundizan en los problemas de normalización de cada uno de los elementos que intervienen en la información propia de un archivo musical personal. Se parte del contexto actual sobre este tipo de archivos, muy valiosos como patrimonio cultural y de gran interés histórico, aunque hasta ahora poco estudiados y muchos de ellos todavía ocultos al conocimiento de investigadores y archiveros. Son archivos, por otra parte, de fondos muy heterogéneos y que a menudo presentan problemas de dispersión y fragmentación de la información. El estado de la situación que se deriva del análisis empírico de la accesibilidad en otros legados personales que tienen como fondo conceptual la música, ha llevado a entender la necesidad de proponer un método de aplicación en el tratamiento documental que aporte soluciones al conocimiento global de la figura objeto de estudio y, por ende, poder extrapolar tal conocimiento al marco sociocultural de la época a la que pertenezca. La metodología, por otra parte, sirve para poner en valor este tipo de archivos, con especial enfoque en el tratamiento de las partituras y obras musicales, así como con particular énfasis en el diseño de un modelo de relaciones sistematizadas entre los distintos fondos que constituyen un archivo musical personal. El sistema permite el tratamiento de los documentos no sólo como entes aislados sino como informaciones de contenido multidireccional.
Big data and learning analytics: Singular or plural?
Authors: Wilson Anna , Thompson Terrie Lynn , Watson Cate , Drew Valerie , Doyle Sarah
Published: April 2017

Recent critiques of both the uses of and discourse surrounding big data have raised important questions as to the extent to which big data and big data techniques should be embraced. However, while the context-dependence of data has been recognized, there remains a tendency among social theorists and other commentators to treat certain aspects of the big data phenomenon, including not only the data but also the methods and tools used to move from data as database to data that can be interpreted and assigned meaning, in a homogenizing way. In this paper, we seek to challenge this tendency, and to explore the ways in which explicit consideration of the plurality of big data might inform particular instances of its exploitation. We compare one currently popular big data-inspired innovation — learning analytics — with three other big data contexts — the physical sciences, business intelligence and public health. Through these comparisons, we highlight some dangers of learning analytics implemented without substantial theoretical, ethical and design effort. In so doing, we also highlight just how plural data, analytical approaches and intentions are, and suggest that each new big data context needs to be recognized in its own singularity.
Some identities involving multiplicative generalized derivations in orime and semiprime rings
Authors: Dhara Basudeb
Published: April 2017

Let $R$ be a ring with center $Z(R)$. A mapping $F:R\rightarrow R$ is called a multiplicative generalized derivation, if $F(xy)=F(x)y+xg(y)$ is fulfilled for all $x,y\in R$, where $g:R\rightarrow R$ is a derivation. In the present paper, our main object is to study the situations: (1) $F(xy)- F(x)F(y)\in Z(R)$, (2) $F(xy)+ F(x)F(y)\in Z(R)$, (3) $F(xy)- F(y)F(x)\in Z(R)$, (4) $F(xy)+ F(y)F(x)\in Z(R)$, (5) $F(xy)- g(y)F(x)\in Z(R)$; for all $x,y$ in some suitable subset of $R$.
Some properties of Generalized Fibonacci difference bounded and $p$-absolutely convergent sequences
Authors: Hazarika Bipan , Das Anupam
Published: April 2017

The main objective of this paper is to introduced a new sequence space $l_{p}(\hat{F}(r,s)),$ $ 1\leq p \leq \infty$ by using the band matrix $\hat{F}(r,s).$ We also establish a few inclusion relations concerning this space and determine its $\alpha-,\beta-,\gamma-$duals. We also characterize some matrix classes on the space $l_{p}(\hat{F}(r,s))$ and examine some geometric properties of this space.
Eigenvalues of the $p(x)-$biharmonic operator with indefinite weight] {Eigenvalues of the $p(x)-$biharmonic operator with indefinite weight under Neumann boundary conditions

Published: April 2017

In this paper we will study the existence of solutions for the nonhomogeneous elliptic equation with variable exponent $\Delta^2_{p(x)} u=\lambda V(x) |u|^{q(x)-2} u$, in a smooth bounded domain,under Neumann boundary conditions, where $\lambda$ is a positive real number, $p,q: \overline{\Omega} \rightarrow \mathbb{R}$, are continuous functions, and $V$ is an indefinite weight function. Considering different situations concerning the growth rates involved in the above quoted problem, we will prove the existence of a continuous family of eigenvalues.
Barriers to Access to and Usage of Financial Services in Ethiopia
Authors: Rao K. Sambasiva , Baza Andualem Ufo
Published: April 2017

We study the interplay between financial exclusion and barriers to inclusion. Our model shows that financially excluded individuals are exposed to barriers to inclusion that prohibit their access to financial services even in absence of voluntary exclusion. We call these situation “involuntary exclusion,” since people lack access to and use of financial services due to barriers to inclusion that are otherwise overlooked social exclusion. We show that barriers to inclusion are more likely to occur when lack of access to physical point of financial services, poverty, lack of credit, prohibitive fixed cost of transacting at financial institution, legal and regulatory barriers and low competition among financial institutions. We analyze financial exclusion as a function of barriers to inclusion, examining the trade-off between unbanked adults and barriers to banking. We verify the model’s prediction that financial exclusion is more likely to occur among low income individuals in which assets holdings are low, as well as individuals who are too far away from physical point of access and those individuals who cannot afford bank fixed charges, than others. We also show that individuals are more likely to be financially excluded (relative to others) in low income groups in which barriers to inclusion are more frequent.

The importance of timely detection, classification and response to anomalies on petroleum products pipeline (PPP) have attracted pragmatic researches in recent times. There is need for efficient monitoring and detection of activities on PPP to guide leak detections and remedy decisions. This paper develops an intelligent hybrid system, driven by discrete event system specification (DEVS) and adaptive neuro-fuzzy inference system (ANFIS) for detection and classification of activities on PPP. A dataset comprising 330 records was used for training, validation and testing of the system. Result of sensitivity test shows that inlet pressure, inlet temperature, inlet volume and outlet volume have cumulative significance of 71.72% on flowrate of PPP. Hybrid learning algorithm was observed to converge faster than the back propagation algorithm in the detection of pipeline activities. ANFIS hybrid learning algorithm with training and testing errors of 0.11980 and 0.010233 yielded a correlation of 0.916 between the computed and the desired output and produced optimal consequent parameters to boost the intelligence of DEVS. A testing error of 0.0303 was observed in the evaluation of DEVS-ANFIS system on 33 test data sample, 32 precise detections were made with one incorrect detection, this gives 96.97% level of confidence in the DEVS-ANFIS model for detection, classification and localization of PPP activities.
Monitoring the Results of the Tutoring Program in its Face-to-Face and Virtual Modalities on the Academic Achievement of Students at a Mexican University
Authors: Cuevas Salazar Omar , García López Ramona Imelda , Vales García Javier José , Cruz Medina Isidro Roberto
Published: April 2017

The tutorship program is aimed at supporting students throughout their university career and its objective is to prevent future problems of adaptation in the educational ambience as well as intervening in matters of academic achievement. At the Instituto Tecnológico de Sonora (Technological Institute of Sonora) (ITSON), the individual tutorship program began in 2000. In 2002 group tutoring began in order to see to the entire first year student population and today group tutoring is offered in both the face-to-face and virtual modalities. The general objective of the present study is to determine the impact the programs of face-to-face and virtual tutoring at the ITSON has had on students’ academic achievement, during the four semesters after having participated in this program. Information on 2,995 students from the different areas of study offered at the university was collected from databases which existed at the Institute and analyzed using different statistical techniques. The tutoring program is shown to have had a favorable impact on the index of students’ failing classes, during the semester they were enrolled in tutoring, but not during the subsequent semesters, during which they did not participate in the tutorship program. The grade point averages obtained by students who had face-to-face tutoring were statistically different from those of the students who did not have tutoring. This was true for all of the semesters analyzed. The same thing happened with the students who had virtual tutoring except for during the second semester when the two were statistically equal.
Kahenman and Tversky’s Research on Heuristics and Its Application to Junior Athletic Development and the College Recruiting Process
Authors: Ryan Brendan M.
Published: April 2017

This paper will apply the work of Amos Tversky and Daniel Kahneman in Prospect theory to the college recruiting process. Prospect theory challenges one of the fundamental ideas of Economics; humans are rational creatures and make rational decisions. The theory demonstrates that in fact, often humans do not make rational decisions and are instead subject to “heuristics”. Heuristics are mental shortcuts individual use to solve problems. The paper will both explain heuristics, as well as demonstrate how coaches, administrators, and junior athletes should be aware of the role of heuristics in both long-termdevelopments, as well as the college recruitment process.
The Learning of Chinese Idiomatic Expressions as a Foreign Language
Authors: Liu Li , Yao Jiayi
Published: April 2017

Chinese idioms are mostly four-character phrases and are called Quadra-syllabic Idiomatic Expressions (QIEs). It has long been reported that learning of Chinese QIEs poses a great challenge for both young L1 speakers and adult L2 learners as the condensed form is often associated with complicated figurative meanings. The present study explored the factors that influence the learning of Chinese QIEs as a Foreign Language (FL). The results of a comprehension test and a questionnaire showed that semantically transparent QIEs were understood much better than opaque ones; being structurally symmetric also facilitated QIE understanding, but with limited effect. Language transfer was another factor to consider especially when the learners were from mixed nationalities. The results were then compared with those reported in the Native Language (NL) QIE learning and were further discussed in terms of the pedagogical implications for the learning of QIEs in FL teaching.
EXPRESSART: A project-based language learning experience
Authors: Barba Javier
Published: April 2017

This article aims to compare two different methodologies (implemented by a single teacher in an practitioner research approach) used in a 4th year English classroom in a public primary school in Catalonia. To do this comparison, different outcomes from students were collected and analysed to answer different questions related to Project Based Language Learning approach (PBLL) and what the author calls Course-Book Driven approach (CBD). The article examines, through the analysis of the students’ productions and of the focus group, the evidence of gains in written language and the motivation of the students depending on the approach used. The article concludes with several implications for research and practice.
Pedagogika Posejdoniosa z Apamei
Authors: Wasilewski Marcin
Published: April 2017

The subject matter and purpose of the article is a depiction of the pedagogical concepts of
Posidonius of Apamea, an eminent stoic philosopher and scholar. As it is clear from the surviving
testimonials of Seneca and Galen, Posidonius dealt in his ethical writings to a large extent
with issues of moral education. In writing On virtues Posidonius undertook – in opposition
to Chrysippus – the question of the origin of ethical defects (moral evil), making insightful
remarks about the nature of children and animals based on empirical observations. Posidonius
believed that moral evil is innate to human nature. And in writing On emotions in reference
to Plato (Politeia, Timaeus and Nomoi dialogues), Posidonius described the typology of human
nature, depending on the type of morphology of the body and the dominant mental element
as well as related types of effective educational methods.
Le « transsexualisme », entre normes sociojuridiques, normes de santé et normes de genre
Authors: Thomas Maud-Yeuse , Espineira Karine
Published: April 2017

L’énoncé de « pratiques à risque » et de pathologies à propos du « transsexualisme » tend à maintenir le contexte d’une norme de santé sur la base d’une majorité « normale » expurgée des singularités minoritaires et générant des politiques ciblées mais conditionnelles, délivrées à partir d’expertises. Leur justification économique permet de dissimuler la violence des dimensions idéologiques qui s’affrontent de part et d’autre du « sain » et du « pathologique ». Les trans sont au centre de ces deux conceptions et semblent en payer le prix. D’un côté une vision tolérante (luttes contre les discriminations, égalité des droits) de l’autre une vision pathologisante conditionnant le cadre de la prise en charge et composant une « prise en charge » définie à partir d’une conception psychopathologiste protégée par un « bouclier thérapeutique » et les normes binaires de genre.

Published: April 2017

Dans le domaine de la santé, Internet participe à la diffusion d’un savoir d’expertise et à son appropriation par les usager.ère.s, ce qui entraîne une reconfiguration des relations avec les professionnel.le.s de la santé. Les résultats d’une enquête pancanadienne mettent en évidence la constitution, grâce à Internet et à ses outils interactifs, d’une expertise collective alternative en matière de santé trans. Celle-ci permet aux personnes trans de contourner les barrières systémiques à l’accès à des soins de santé adéquats, favorise leur autonomisation dans leur choix médicaux et renforce leur capacité à négocier leur rapport au système médical.
