Influence of light conditions on the allometry and growth of the understory palm Geonoma undata subsp. edulis (Arecaceae) of neotropical cloud forests
Authors: Sylvester Olivia , Avalos Gerardo 
Published: November 2013

• Premise of the study: Knowledge on the growth responses of understory palms to changing light conditions within neotropical cloud forests is limited. The low light regime of these environments, in addition to persistent cloudiness, low ambient temperatures, and slow nutrient cycles, imposes significant constraints on biomass accumulation. Here, we evaluate how changes in the understory light conditions influenced the allometry and growth of G. undata subsp. edulis in two cloud forests in Costa Rica.• Methods: We examined the structural relationships between stem diameter, stem height, and crown area in reproductive and nonreproductive individuals. We related the variation in stem growth and crown area with allometry, leaf production and longevity, and light conditions that we measured using hemispherical photographs over 1 year.• Key results: The allometric and growth pattern of G. undata subsp. edulis was characterized by its investment in crown area, which was strongly and positively related to increments in palm height and reproduction. Growth, measured as the increase in crown area and stem height, was not explained by the variation in the light regime spanning 1 year. However, reproductive individuals were generally taller, more slender, and had larger leaf areas than nonreproductive individuals.• Conclusions: Our results demonstrated that stem growth responses were mostly controlled by initial crown size rather than by temporal differences in the understory light regimes of cloud forests. These results suggest that cloud forest understory palms have a limited capacity to respond to light changes and rely mostly on an opportunistic strategy for biomass accumulation and reproduction.

The aim of the present submission is to show the results of the study carried out with 199 students of journalism degree from the University of Valladolid. This experience evaluates to what extend blogs promote individual and group competences and skills, with the goal to determine the advantages and disadvantages of collaborative learning in the virtual environment of the blogosphere. New hybrid weblogs, audioblogs and tvblogs, have been used for practical on the subjects of News on Radio and News on Television for two consecutive courses. The experience has shown great usefulness not only in building the horizontal knowledge about the journalistic work from the classroom, the labs, and in their individual work outside the university environment, but it has also contributed positively to their community integration, enhancing negotiated decision-making and respect for the work of the others. These multimedia logs have enabled students to participate in the creation of content, in the production process, corporate design, bringing out and social media distribution, while learning to organize every element in harmonious and consistent way in order to create an independent audiovisual product related to other webs that can be used as documentary, specialized or critical complement. This collaborative experience has joined creativity, initiative, self-assessment and knowledge of online news production.El propósito de la aportación es mostrar la experiencia llevada a cabo con 199 alumnos del Grado de Periodismo de la Universidad de Valladolid para analizar hasta qué punto los blogs potencian habilidades y competencias individuales y grupales, con el objetivo de determinar las ventajas y los retos del aprendizaje colaborativo en el entorno virtual de la blogosfera. Para ello se han utilizado nuevos formatos híbridos, «audioblogs» y «tvblogs», con los que se han construido las prácticas para las asignaturas de «Radio Informativa» y «Televisión Informativa durante dos cursos consecutivos. La experiencia ha demostrado una notable eficacia no sólo en la construcción horizontal de su conocimiento sobre la profesión periodística desde el aula, los laboratorios y su trabajo individual fuera del entorno universitario, sino que ha contribuido positivamente a su integración comunitaria, potenciando la toma de decisiones negociadas y el respeto al trabajo de los demás. Estas formas multimedia han permitido a los alumnos participar en la creación de los contenidos, en el proceso de producción, diseño corporativo, edición y distribución social, mientras aprendían a organizar cada elemento de forma armónica, coherente, para construir un producto audiovisual independiente que se relaciona a su vez con otras web que sirven de complemento documental, especializado o crítico. Esta experiencia colaborativa ha unido en su elaboración creatividad, iniciativa, actividad continua, autoevaluación y conocimiento de la producción periodística en Internet.
Adolescent students as media fictional characters
Authors: Falcón-Díaz-Aguado Laia , Díaz-Aguado-Jalón María-José 
Published: November 2013

Media fictional narrations on adolescents as characters and target are used by teenage audiences when looking for references for their identity building. As a starting point for Media Literacy activities to help teenage students in this process, this research focuses on the representations of adolescent students proposed by different kinds of media fictional narrations. Three European narrations have been chosen in order to analyse and compare different genres, codes and values: the television series «Física o Química» and the films «Harry Potter and the Order of the Phoenix» and «The Class». A classic narrative analysis approach has been applied in order to encourage teachers to use this kind of Media Literacy activities by employing methodologies that they are familiar with. The results show that such a methodology could facilitate the comparative analysis of important coincidences between these examples (such as the importance of friendship and couple relationships) and also underlines meaningful differences (like the orientation towards the future). The conclusion reached is that the comparison between such different kinds of media fictional narrations is a useful educational tool for improving Media Literacy skills and helping teenage students in the identification of the values and images they really want to choose as reference and inspiration for their own identity building.
Los relatos audiovisuales que tienen a los adolescentes como audiencia y protagonistas son utilizados por éstos para buscar referencias con las que construir su identidad. Esta investigación busca comprender cómo es la identidad de los estudiantes adolescentes en distintos tipos de relatos audiovisuales de ficción, como punto de partida para la elaboración de materiales de alfabetización mediática que les ayude en dicho proceso. Para ello se seleccionaron tres narraciones europeas recientes sobre la vida escolar de adolescentes, con las que poder contrastar entre géneros, códigos y valores: la serie televisiva «Física o Química» y las películas «Harry Potter y la Orden del Fénix» y «La clase». El método ha sido el análisis textual de tipo cualitativo, utilizando como categorías las de la morfología del relato clásico. Los resultados reflejan que dicho esquema, familiar para el profesorado de Literatura, permite detectar importantes coincidencias entre relatos (como la importancia de las relaciones de pareja y amistad…), que hacen más significativas las diferencias del contraste (como la orientación hacia el futuro o el valor del pensamiento y del profesorado en dicho proceso). Se concluye que la comparación entre los tres tipos de relatos representa un óptimo recurso para la alfabetización mediática así como para ayudarles a tomar conciencia de cuáles son los valores con los que quieren identificarse y los problemas que pueden obstaculizarlos.
Educational possibilities of social networks and group work. University students’ perceptions
Authors: Cabero-Almenara Julio , Marín-Díaz Verónica 
Published: November 2013

The change in classroom methodologies has in many cases come with the emergence of the Internet and 2.0 tools (mainly social networks). The development of a constructivist approach focused on group work means that students’ training can be improved by this type of resources as they foster important aspects such as socialization, information searching and the achievement of a common goal, etc. This work aims to analyze the information and communication technology (ICT) university learning processes and student preferences for working either inside or outside the classroom at the universities of Córdoba, Sevilla, Huelva and the Basque Country. Our objectives are focused on knowing: the students’ feelings on social software and its influence on collaborative and group work;) the social network tools they use and, if there are any differences between these universities in terms of collaborative work perceptions. The instrument for data gathering was a four-dimensional questionnaire. The main results are: students are interested in group work as a type of classroom methodology; students have little knowledge of technology tools (except for social networks). These results provide a reliable diagnostic instrument for the variables that comprise this tool.
El cambio en las metodologías de aula viene de la mano, en muchos casos, de Internet y de las herramientas de la Web 2.0. Por otra parte, el desarrollo de una perspectiva de corte constructivista apoyado en el trabajo en grupo, suponen que la formación de los estudiantes puede ser alimentada a través de este tipo de recursos, dado que potencia, entre otros aspectos la socialización, la búsqueda de información, el logro de una meta común, etc. La investigación que aquí se presenta versa sobre la realidad de los procesos de aprendizaje universitario con TIC y las preferencias para trabajar dentro y fuera del aula de los estudiantes de las universidades de Córdoba, Huelva, Sevilla y País Vasco. Los objetivos se centran en conocer las percepciones que los alumnos tienen sobre el software social y el trabajo en grupo y colaborativo, cuáles son las herramientas de software social que emplean y si hay diferencias en función de la universidad de procedencia. Se empleó como instrumento de recogida de datos un cuestionario conformado por cuatro dimensiones. Se concluye que el alumnado está interesado en el empleo del trabajo en grupo como metodología de aula, así como su escaso conocimiento de las herramientas tecnológicas, salvo de las redes sociales. Al mismo tiempo, estos resultados aportan un instrumento fiable para el diagnóstico de las variables que lo conforman.
Troubles alimentaires chez des patients adultes : se rêver en devenir
Authors: Cavalli Alessandra , Hainsworth Karen 
Published: November 2013

Dans cet article, nous examinerons le matériel clinique de l’analyse d’une patiente souffrant de troubles alimentaires, avec une attention particulière pour les rêves qui ont émergé pendant le travail thérapeutique. Ces rêves ont donné vie au vide effrayant que la patiente ressentait en elle et qu’elle essayait de combler par la nourriture ou le désir de fusion avec l’autre. Pendant l’analyse, ces troubles alimentaires se transformèrent progressivement en affects et en émotions, des aspects d’elle que la patiente n’avait pas été capable de tolérer jusque-là. Plus la patiente a eu accès à ses rêves, et à la possibilité de ressentir, moins elle a eu besoin de recourir à son trouble alimentaire pour échapper à la part clivée de son monde intérieur qu’elle ne connaissait jusqu’alors que comme un « vide ».
Quand les rêves sauvent la vie par le sens

Published: November 2013

Ophélie, une femme d’une soixantaine d’années, figée dans l’image de la jeunesse éternelle pour garder l’amour de son père, restait enfermée dans une sorte de mort invisible où elle vivait une fausse vie, une vie de fantôme. Elle était comme une femme en plastique, arrêtée dans son évolution à un stade œdipien. Une mort véritable, celle de son mari, est venue la délivrer de l’adolescente puérile qui agissait en elle – elle a commencé à vieillir de manière accélérée – ce qui, dans le même temps, venait la mettre en danger d’être engloutie dans cette mort. Grâce au travail sur ses rêves, la régénération s’est produite dans le cœur, par la déchirure de la poitrine d’un homme oiseau, figure de père cosmique. Elle a pu alors renaître sous la forme d’une très belle vieille femme ridée.
Rêves en période de catastrophe
Authors: Zoja Luigi , Hainsworth Karen 
Published: November 2013

Selon Jung, les rêves de certaines personnes, dans certaines circonstances, peuvent exprimer sous une forme concentrée, la souffrance de tout un groupe ou de tout un peuple. Dans cet article, je considère deux rêves de Primo Levi, écrivain juif italien survivant d’Auschwitz, et deux rêves de Michihiko Hachiya, médecin-chef de l’Hôpital des Communications d’Hiroshima, faits au moment du bombardement atomique de la ville. Ces rêves évoquent une situation critique qui dépasse de loin l’expérience personnelle. Toutefois, peu de chose dans ces rêves semble relié aux terribles catastrophes qui les a fait naître : ils expriment plutôt une forme d’aliénation globale, presqu’impensable. Ils semblent davantage reliés à l’anonymat potentiel extrême de la vie moderne qu’à la souffrance d’une expérience aux portes de la mort.
Rêves de la Première Guerre mondiale : récits transitionnels ?
Authors: Renard Delphine 
Published: November 2013

L’historienne Mireille Bélis a rassemblé une centaine de récits de rêves datant de la Première Guerre mondiale, et en a sollicité la lecture par un psychanalyste. Dans cet ensemble, une série d’une quarantaine de rêves d’un jeune intellectuel attire notre attention par l’impression de « sur place » qui s’en dégage, au contraire de la dynamique relevée par Jung à l’intérieur des séries qu’il étudie. À l’opposé des rêves traumatiques qui présentent toujours à nouveau l’effroi diurne, ceux-ci évoquent des instants de bonheur familial en temps de paix. Ces rêves ne nous sont parvenus que parce qu’ils ont fait l’objet de récits, destinés à être lus, en général, par les destinataires des lettres, donc pris dans une relation transférentielle. Nous formulons l’hypothèse selon laquelle ces récits auraient la même fonction que les objets transitionnels de Winnicott. Ils constituent un entre-deux qui relie le rêveur, submergé par sa détresse, à un représentant de la mère suffisamment bonne des origines, lui permettant de surmonter la puissance désorganisatrice de la déréliction.

SummaryBackground: Kidney disease is under-documented in physician notes. The use of template-guided notes may improve physician recognition of kidney disease early in training.Objective: The objective of this study was to determine whether a computerized inpatient renal template note with clinical decision support improves resident knowledge and documentation of kidney disease.Methods: In this prospective study, first year medical residents were encouraged to use the renal template note for documentation over a one-month period. The renal template note included an option for classification of acute kidney injury (AKI) and chronic kidney disease (CKD) categories with a link to standard classifications. Pre- and post-knowledge of AKI and CKD categories was tested with a quiz and surveys of resident experience with the intervention were conducted. Appropriate AKI and/or CKD classification was determined in 100 renal template notes and 112 comparable historical internal medicine resident progress notes from approximately one year prior.Results: 2,435 inpatient encounters amongst 15 residents who participated were documented using the renal template note. A significantly higher percent of residents correctly staged earlier stage CKD (CKD3) using the renal template note compared to historical notes (9/46 vs. 0/33, p<0.01). Documentation of AKI and more advanced CKD stages (CKD4 and 5) did not improve. Knowledge based on quiz scores increased modestly but was not significant. The renal template note was well received by residents and was perceived as helping improve knowledge and documentation of kidney disease.Conclusions: The renal template note significantly improved staging of earlier stage CKD (CKD3) with a modest but non-significant improvement in resident knowledge. Given the importance of early recognition and treatment of CKD, future studies should focus on teaching early recognition using template notes with supplemental educational interventions.Citation: Shirazian S, Wang R, Moledina D, Liberman V, Zeidan J, Strand D, Mattana J.

Individual‐level socioeconomic status and community‐level inequality as determinants of stigma towards persons living with HIV who inject drugs in Thai Nguyen, Vietnam
Authors: Lim Travis , Zelaya Carla , Latkin Carl , Quan Vu Minh , Frangakis Constantine , Ha Tran Viet , Minh Nguyen Le , Go Vivian 
Published: November 2013

IntroductionHIV infection may be affected by multiple complex socioeconomic status (SES) factors, especially individual socioeconomic disadvantage and community‐level inequality. At the same time, stigma towards HIV and marginalized groups has exacerbated persistent concentrated epidemics among key populations, such as persons who inject drugs (PWID) in Vietnam. Stigma researchers argue that stigma fundamentally depends on the existence of economic power differences in a community. In rapidly growing economies like Vietnam, the increasing gap in income and education levels, as well as an individual's absolute income and education, may create social conditions that facilitate stigma related to injecting drug use and HIV.MethodsA cross‐sectional baseline survey assessing different types of stigma and key socioeconomic characteristics was administered to 1674 PWID and 1349 community members living in physical proximity throughout the 32 communes in Thai Nguyen province, Vietnam. We created four stigma scales, including HIV‐related and drug‐related stigma reported by both PWID and community members. We then used ecologic Spearman's correlation, ordinary least‐squares regression and multi‐level generalized estimating equations to examine community‐level inequality associations, individual‐level SES associations and multi‐level SES associations with different types of stigma, respectively.ResultsThere was little urban–rural difference in stigma among communes. Higher income inequality was marginally associated with drug‐related stigma reported by community members (p=0.087), and higher education inequality was significantly associated with higher HIV‐related stigma reported by both PWID and community members (p<0.05). For individuals, higher education was significantly associated with lower stigma (HIV and drug related) reported by both PWID and community members. Part‐time employed PWID reported more experiences and perceptions of drug‐related stigma, while conversely unemployed community members reported enacting lower drug‐related stigma. Multi‐level analysis revealed that the relationship between education inequality and HIV‐related stigma is superseded by the effect of individual‐level education.ConclusionsThe results of the study confirm that socioeconomic factors at both the individual level and community level affect different types of stigma in different ways. Attention should be paid to these differences when planning structural or educational interventions to reduce stigma, and additional research should investigate the mechanisms with which SES and inequality affect social relationships and, in turn, stigma.
Implementing a stigma reduction intervention in healthcare settings
Authors: Li Li , Lin Chunqing , Guan Jihui , Wu Zunyou 
Published: November 2013

IntroductionGlobally, HIV‐related stigma is prevalent in healthcare settings and is a major barrier to HIV prevention and treatment adherence. Some intervention studies have showed encouraging outcomes, but a gap continues to exist between what is known and what is actually delivered in medical settings to reduce HIV‐related stigma.MethodsThis article describes the process of implementing a stigma reduction intervention trial that involved 1760 service providers in 40 hospitals in China. Guided by Diffusion of Innovation theory, the intervention identified and trained about 15–20% providers as popular opinion leaders (POLs) to disseminate stigma reduction messages in each intervention hospital. The intervention also engaged governmental support in the provision of universal precaution supplies to all participating hospitals in the trial. The frequency of message diffusion and reception, perceived improvement in universal precaution practices and reduction in the level of stigma in hospitals were measured at 6‐ and 12‐month follow‐up assessments.ResultsWithin the intervention hospitals, POL providers reported more frequent discussions with their co‐workers regarding universal precaution principles, equal treatment of patients, provider‐patient relationships and reducing HIV‐related stigma. Service providers in the intervention hospitals reported more desirable intervention outcomes than providers in the control hospitals. Our evaluation revealed that the POL model is compatible with the target population, and that the unique intervention entry point of enhancing universal precaution and occupational safety was the key to improved acceptance by service providers. The involvement of health authorities in supporting occupational safety was an important element for sustainability.ConclusionsThis report focuses on explaining the elements of our intervention rather than its outcomes. Lessons learned from the intervention implementation will enrich the development of future programs that integrate this or other intervention models into routine medical practice, with the aim of reducing HIV‐related stigma and improving HIV testing, treatment and care in medical settings.
