Dos formatos (papel y online) de un programa educativo para la mejora del autoconcepto físico

[Es] El autoconcepto físico juega un papel decisivo en el bienestar personal y la prevención de trastornos y dificultades de conducta. De ahí la importancia de ayudar educativamente al desarrollo de adecuadas autopercepciones físicas. En este artículo se ofrece un análisis comparativo de dos formatos (papel y on line) de un mismo programa de intervención educativa para la mejora del autoconcepto implementado con estudiantes universitarios. Los datos obtenidos en la medida del autoconcepto físico no confirman una mejora significativa, lo cual no necesariamente desacredita el programa ya que puede atribuirse en parte a determinadas limitaciones observadas en la aplicación del mismo. Por otra parte, la valoración del programa que realizan los sujetos participantes es notablemente positiva, en particular, la de quienes han utilizado la versión on line.

Integrated treatment of first episode psychosis with online training (e-learning): study protocol for a randomised controlled trial

Background: The integrated treatment of first episode psychosis has been shown to improve functionality and negative symptoms in previous studies. In this paper, we describe a study of integrated treatment (individual psychoeducation complementary to pharmacotherapy) versus treatment as usual, comparing results at baseline with those at 6-month re-assessment (at the end of the study) for these patients, and online training of professionals to provide this complementary treatment, with the following objectives: 1) to compare the efficacy of individual psychoeducation as add-on treatment versus treatment as usual in improving psychotic and mood symptoms; 2) to compare adherence to medication, functioning, insight, social response, quality of life, and brain-derived neurotrophic factor, between both groups; and 3) to analyse the efficacy of online training of psychotherapists. Methods/design: This is a single-blind randomised clinical trial including patients with first episode psychosis from hospitals across Spain, randomly assigned to either a control group with pharmacotherapy and regular sessions with their psychiatrist (treatment as usual) or an intervention group with integrated care including treatment as usual plus a psychoeducational intervention (14 sessions). Training for professionals involved at each participating centre was provided by the coordinating centre (University Hospital of Alava) through video conferences. Patients are evaluated with an extensive battery of tests assessing clinical and sociodemographic characteristics (Positive and Negative Syndrome Scale, State-Trait Anxiety Inventory, Liebowitz Social Anxiety Scale, Hamilton Rating Scale for Depression, Scale to Assess Unawareness of Mental Disorders, Strauss and Carpenter Prognostic Scale, Global Assessment of Functioning Scale, Morisky Green Adherence Scale, Functioning Assessment Short Test, World Health Organization Quality of Life instrument WHOQOL-BREF (an abbreviated version of the WHOQOL-100), and EuroQoL questionnaire), and brain-derived neurotrophic factor levels are measured in peripheral blood at baseline and at 6 months. The statistical analysis, including bivariate analysis, linear and logistic regression models, will be performed using SPSS. Discussion: This is an innovative study that includes the assessment of an integrated intervention for patients with first episode psychosis provided by professionals who are trained online, potentially making it possible to offer the intervention to more patients.

El papel de internet en la convergencia cultural: un análisis teórico basado en la aproximación constructivista dinámica desde la perspectiva de las interacciones online de los consumidores

[ES] Este trabajo plantea y analiza, con un enfoque teórico, el papel que puede tener Internet como factor impulsor clave de la convergencia cultural entre países. En este respecto, se reflexiona en torno a una propuesta teórica central, tomando como base principal la aproximación cultural constructivista dinámica. En esencia, se teoriza sobre cómo los valores compartidos por parte de los individuos (consumidores) procedentes de diferentes culturas en este medio, fruto de procesos interactivos e iterativos de comunicación online, pueden ser transferidos de manera plausible a cada una de sus culturas primarias o de origen, fomentando, por tanto, la aproximación de las mismas en el largo plazo.

Los determinantes de la confianza del comprador online. Comparación con el caso de subasta

[ES] Los trabajos de investigación sobre comercio electrónico en Internet ocupan gran parte de la investigación de marketing, pero son pocos aún los que se han ocupado de estudiar el sistema de subasta. Ante las peculiares características de una compra online, transmitir confianza al consumidor en este contexto es uno de los retos más importantes y difíciles en comparación con la compra offline. No obstante, es de esperar que las señales generadoras de confianza sean diferentes en la compra online por subasta que en la compra online en otros sitios web.

Online exercise for the design and simulation of PCR and PCR-RFLP experiments

[EN] Background: Polymerase Chain Reaction (PCR) and Restriction Fragment Length Polymorphism of PCR products (PCR-RFLP) are extensively used molecular biology techniques. An exercise for the design and simulation of PCR and PCR-RFLP experiments will be a useful educational tool. Findings: An online PCR and PCR-RFLP exercise has been create that requires users to find the target genes,compare them, design primers, search for restriction endonucleases, and finally to simulate the experiment. Each user of the service is randomly assigned a gene from Escherichia coli; to complete the exercise, users must design an experiment capable of distinguishing among E. coli strains. By applying the experimental procedure to all completely sequenced E. coli, a basic understanding of strain comparison and clustering can also be acquired. Comparison of results obtained in different experiments is also very instructive. Conclusions: The exercise is freely available at http://insilico.ehu.es/edu.

ENEKuS – a key model for managing the transformation of the normalisation of the Basque language in the workplace

The aim of this study is to develop a reference model for intervention in the language processes applied to the transformation of language normalisation within organisations of a socio-economic nature. It is based on the case study of an experience carried out over10 years within a trades’ union confederation, and has pursued a strategy of a basically qualitative research carried out in three stages: 1) undertaking field work through application of action-research methodology, 2) reconstructing experiences following processes of systematisation and conceptualisation of the systematised data, applying methodologies for the Systematisation of Experiences and Grounded Theory, and 3) formulating a model for intervention, applying the Systems Approach methodology. Finally, we identified nine key ideas that make up the conceptual framework for the ENEKuS reference model, which is structured in nine ‘action points', each having an operating sub-model applicable in practice.

Online journalism: research methods. A multidisciplinary approach in comparative perspective

Journalism on digital networks, and specifically on Internet, is a relatively recent phenomenon, whose spread began in approximately 1994, in parallel to that of the World Wide Web. Study of this new communicative phenomenon began simultaneously in several countries. This, in its turn, was helped by the new possibilities for communication amongst academics - electronic mail, predating the WWW, was, and is, one of the most widely used tools of the university community. The spread of these new forms of global communication helped to raise mutual awareness between research groups, making it possible to form increasingly broad and cohesive networks.

Uptake and factors that influence the use of 'sit less, move more' occupational intervention strategies in Spanish office employees

Background: Little is known about the types of 'sit less, move more' strategies that appeal to office employees, or what factors influence their use. This study assessed the uptake of strategies in Spanish university office employees engaged in an intervention, and those factors that enabled or limited strategy uptake. Methods: The study used a mixed method design. Semi-structured interviews were conducted with academics and administrators (n = 12; 44 +/- 12 mean SD age; 6 women) at three points across the five-month intervention, and data used to identify factors that influenced the uptake of strategies. Employees who finished the intervention then completed a survey rating (n = 88; 42 +/- 8 mean SD age; 51 women) the extent to which strategies were used [never (1) to usually (4)]; additional survey items (generated from interviewee data) rated the impact of factors that enabled or limited strategy uptake [no influence (1) to very strong influence (4)]. Survey score distributions and averages were calculated and findings triangulated with interview data. Results: Relative to baseline, 67% of the sample increased step counts post intervention (n = 59); 60% decreased occupational sitting (n = 53). 'Active work tasks' and 'increases in walking intensity' were the strategies most frequently used by employees (89% and 94% sometimes or usually utilised these strategies); 'walk-talk meetings' and ` lunchtime walking groups' were the least used (80% and 96% hardly ever or never utilised these strategies). 'Sitting time and step count logging' was the most important enabler of behaviour change (mean survey score of 3.1 +/- 0.8); interviewees highlighted the motivational value of being able to view logged data through visual graphics in a dedicated website, and gain feedback on progress against set goals. 'Screen based work' (mean survey score of 3.2 +/- 0.8) was the most significant barrier limiting the uptake of strategies. Inherent time pressures and cultural norms that dictated sedentary work practices limited the adoption of 'walk-talk meetings' and ` lunch time walking groups'. Conclusions: The findings provide practical insights into which strategies and influences practitioners need to target to maximise the impact of 'sit less, move more' occupational intervention strategies.

El discurso en el estudio de las organizaciones. Una revisión de la literatura

[ES] En el documento se presenta una revisión de la literatura referente al discurso en el estudio de las organizaciones, que parte de sus fundamentos teóricos y sus principales aportes. La unidad de análisis fueron 88 textos seleccionados en una revisión sistemática de 5.509 artículos, publicados entre 2000 y 2012, en diez de las principales revistas internacionales relacionadas con la temática definida. Para relevar y categorizar los datos pertinentes, se utilizó el software de investigación cualitativa Atlas.ti, versión 6.2. La comprensión de la información se complementó con métodos de análisis de contenido y de frecuencia. De los principales resultados se infirieron cuatro dimensiones del discurso: instrumental, simbólica, estratégica y comunicacional. Además, se realizó una clasificación de los artículos con base en los enfoques sobre el discurso y las temáticas organizacionales estudiadas. Los aportes encontrados en dicha revisión permiten plantear que el discurso no solo es lo dicho sino también aquello que ha sido silenciado en la organización, campo de investigación que ha sido poco explorado en los textos analizados. Este artículo realiza contribuciones importantes para el área administrativa y organizacional, en especial para todos aquellos profesionales que se interesen por el análisis de las organizaciones desde la perspectiva del discurso, tanto en la academia como en la asesoría e intervención en ellas.

Linking transformational leadership and organizational trust: has organizational commitment a mediating effect on it?

[EN] The main goal of this study is to analyze how organizational commitment has a mediating effect on the relation between transformational leadership and organizational trust. Therefore we developed an organization analysis based on a survey that was used to collect primary data from a sample of 58 employees. We obtained a 71% response rate and these data were analyzed using quantitative methodological techniques and linear regression. The research was conducted at the Serralves Foundation (Porto, Portugal) to empirically test the proposed research model and its hypotheses. The empirical results confirm that transformational leadership positively enhances organizational trust. However, transformational leadership and organizational trust are not significantly influenced by organizational commitment, thus not having a mediating effect on this relationship. Such results assume particular relevance because they become a basis for comparative studies in similar organizations. This study brings some theoretical contributions to the literature by analyzing the mediating effect of organizational commitment on the relation between transformational leadership and organizational trust in cultural organizations and has also some practical management implications, as it draws attention to the importance of a set of practices, job satisfaction oriented, which can effectively lead to organizational commitment intervention in the relationship between transformational leadership and organizational trust.
