Meeting Veterans Where They're @: A VA Home-Based Telemental Health (HBTMH) Pilot Program
Authors: Shore Peter , Goranson Anders , Ward Mark F. , Lu Mary W. 
Published: October 2014

Objectives: The first Home-Based Telemental pilot program (HBTMH) in the Department of Veterans Affairs addresses the significant challenge of access to mental health treatment for rural veterans. Though the feasibility of telemental healthcare in clinic-based settings has been well documented, the feasibility of telemental health via webcam and computer in a patient's home or other non-clinic settings is unknown. Methods: The HBTMH program, established in December 2009 at the Portland VA Medical Center, delivers a wide range of mental health services into the homes and other non-clinic settings of rural veterans via webcam, secure and encrypted software and veteran-owned personal computers. The program adhered to a Standard Operating Procedure (SOP) Manual, evaluated patients with the Assessment for Suitability for Home Based Telemental Health (ASH-25), utilized a Patient Support Person (PSP), and incorporated a peer technical consultant to provide assistance to veterans. The authors describe satisfaction and safety survey results from the initial 40 veterans enrolled. Results: Survey results support the feasibility and safety of using webcams, secure/encrypted software and veteran-owned personal computers for the delivery of mental health services into the home. Veterans report high levels of satisfaction and perceived safety with home-based telemental health. Results also suggest fewer no-show appointments in home-based telemental health compared to clinic-based telemental health. Conclusions: The authors discuss the strength and limitations of the program as well as potential areas of future research.

Published: October 2014

Objective: Adolescent depression is a major public health concern. Efficacious interventions exist, but are underutilized. Novel approaches to improving access are therefore a top priority. Web-based approaches offer a viable treatment delivery solution; this approach may reach adolescents who might not otherwise receive formal treatment. Behavioral activation (BA) approaches have had success in treatment of depressive symptoms in youth. The purpose of this article is to: (1) describe the development process of a web-based, behavioral activation intervention for adolescents; (2) summarize the preliminary feasibility data; and (3) discuss the benefits and challenges associated with development and evaluation of adolescent self-help resources. Methods: The current study is part of a larger NIMH funded study focusing on the development and evaluation of Bounce Back Now (BBN), an evidence-informed, web resource for disaster-affected adolescents and their families. This study is specifically on the development of the BA component of the mood module of BBN, which was evaluated more extensively than other components. We present data from a formal usability evaluation conducted with 24 adolescents, and preliminary usage data collected from 2,000 disaster affected adolescents recruited from the tornado-affected coordinates in Alabama and Joplin, MO. Results: Preliminary data supported the feasibility of this approach: qualitative data with the clinic-based sample revealed favorable reactions to the intervention, and preliminary data from the large ongoing randomized controlled trial have indicated moderate levels of access. Conclusions: Brief, web-based approaches may offer a promising alternative to address access barriers for adolescents with depressed mood.

Published: October 2014

• Premise of the study: High‐quality information about threatened species is required to prevent current global biodiversity losses. Lichens are important components of forest biodiversity and help to maintain ecosystem functioning. The epiphytic cyanolichen Lobarina scrobiculata is red‐listed in Europe and North America, but knowledge of its ecology and distribution in Southern Europe is scarce.• Methods: We used a multispatial scale design to investigate the effects of macroclimate, forest structure, tree features, and microhabitat on the occurrence, abundance, spatial distribution, and performance of Lobarina scrobiculata in the Iberian Peninsula at plot and tree scales. Generalized linear models and mixed models were used for analysis.• Key results: We recorded ca 14000 individuals of the threatened species Lobarina scrobiculata from 22 populations in the Iberian Peninsula. Our results suggest that L. scrobiculata thrives mainly in oak forests with highly variable annual precipitation levels. At the plot scale, the L. scrobiculata abundance increased with annual precipitation and tree density (habitat quantity). At the tree scale, our models highlighted the importance of tree size and bark roughness (habitat quality) as the main drivers of species occurrence and abundance. We detected a marked spatial pattern on tree trunks, i.e., L. scrobiculata occurred preferentially on north‐facing surfaces and close to the ground where humidity is higher.• Conclusions: By integrating multiscale modeling, we analyzed a unique large dataset and these results are essential for understanding the ecology of this threatened cyanolichen. There is an urgent need to preserve the forests that this species currently inhabits as well as potential colonization sites.

Published: October 2014

At the end of the first decade of the 21st century, the rapid growth in the MOOC offering brought about a new educational landscape, posing new challenges to teaching and learning, mainly due to massive participation, ubiquity and free enrollment. These courses embody a confluence of technological and pedagogical mediations yet to be fully explored. This study, applying an instrument of educational and interactive indicators on a MOOC (INdiMOOC-EdI) designed by the authors, seeks to ascertain the pedagogical components of MOOCs delivered in the Spanish language in order to establish which course features are platform dependent. An exploratory sequential mixed methods study was carried out on a total of 117 courses within 10 different platforms via an instrument developed and validated ad hoc. The data obtained is subjected to a content analysis for a qualitative perspective; while a quantitative perspective is obtained through a statistical analysis complemented with classification algorithms typical in data mining. The results suggest that the different platform providers condition the pedagogical design of the MOOC in five key areas: learning, activities and tasks, means and resources, interactivity and assessment. It concludes with a series of descriptive, educational and interactive indicators that can be a pedagogical benchmark for future MOOCs.
A finales de la primera década del siglo XXI, el rápido aumento de cursos MOOC dibuja un nuevo panorama educativo planteando nuevos retos a la enseñanza y al aprendizaje debido, fundamentalmente, a sus características de masividad, ubicuidad y gratuidad. En estos cursos se da una confluencia de mediaciones tecnológicas y pedagógicas aún por explorar en todas sus dimensiones. Este trabajo, utilizando un instrumento de indicadores educativos e interactivos en un MOOC (INdiMOOC-EdI) de elaboración propia, se centra en averiguar qué componentes pedagógicos posee la actual oferta de MOOC en lengua hispana, para poder dirimir aquellos elementos dependientes de las plataformas que los soportan. Para ello se realiza una investigación mixta de tipo exploratoria y secuencial que analiza un total de 117 cursos ubicados en 10 plataformas diferentes, utilizando el instrumento creado y validado a tal efecto. Con la información obtenida se lleva a cabo un análisis de contenido en su vertiente cualitativa, mientras que con la cuantitativa se efectúan análisis estadísticos complementados con algoritmos propios de la minería de datos. Los resultados muestran que las diferentes plataformas condicionan los diseños pedagógicos del MOOC en cinco aspectos fundamentales: el aprendizaje, las actividades y tareas, los medios y recursos, la interactividad y la evaluación. Se concluye con una serie de indicadores de tipo descriptivo, formativo e interactivo que pueden orientar la pedagogía de futuros Cursos Online Masivos Abiertos.

Published: October 2014

The use of video as a teaching resource stimulates the construction of new knowledge. Although this resource exists in several genres and media, the experience of professionals that use this resource in class is not appreciated. Furthermore, online spaces guiding and supporting the appropriate use of this practice are unavailable. In the online learning field, a proposal has emerged for a repository of short videos aimed at instructing how to use them as a teaching resource in order to stimulate the exchange of ideas and experience (fostering and creating knowledge) in the teaching-learning process, which serves as a resource for professionals in the construction of MOOCs (Massive Open Online Courses). A three-stage architecture is methodologically proposed: identification/recognition, dissemination and collaboration in the use of videos as a teaching resource supported by an extensive exploratory research, based on existing educational technologies and technological trends for higher education. And this leads to the creation of a repository of Informational Content Recovery in Videos (RECIF), a virtual space for the exchange of experience through videos. We conclude that through methodologies that facilitate the development of innovative processes and products, it is possible to create spaces for virtual or face-to-face motivational classes (MOOCs) thereby completing an interactive and collaborative learning toward stimulation of creativity and dynamism.
El uso de vídeos como recurso didáctico estimula la construcción de nuevo conocimiento. A pesar de la existencia de este recurso en diversos géneros y medios, no se valora la experiencia de los profesionales que lo aprovechan en clase y además no se cuenta con espacios online que orienten y apoyen el uso apropiado de esta práctica. En el ámbito del aprendizaje online, surge la propuesta de un repositorio de vídeos de corta duración, con el objetivo de orientar acerca de su uso como recurso didáctico, a fin de incentivar un intercambio de ideas y experiencias (fomentar y crear conocimiento), en el proceso enseñanza-aprendizaje, sirviendo esto como recurso para profesionales en la construcción de los MOOC (Massive Open Online Courses). Metodológicamente se propone una arquitectura en tres etapas: identificación/reconocimiento, diseminación y colaboración, para el uso de vídeos como recurso didáctico, sustentándose en una extensa investigación exploratoria, basándose en las tecnologías educativas existentes y tendencias tecnológicas para la educación superior. El resultado es la creación de un repositorio de Recuperación de Contenido de Información en Vídeos (RECIF), un espacio virtual de intercambio de experiencias por medio de vídeos. Se concluye que por medio de metodologías que faciliten el desarrollo de procesos y productos innovadores, se pueden crear espacios de clases motivadoras, virtuales o presenciales, que completen un aprendizaje interactivo y colaborativo, estimulando la creatividad y el dinamismo.

Published: October 2014

A striking increase in the use of new information and communication technology has come about in recent years. This study analysed the characteristics and habits of Internet use in a sample of pre-adolescents between 10 and 13 years of age, enrolled in the 6th grade of primary school in Navarra (Spain). Likewise, the existence of differential patterns in Internet use by sex was analysed, and risk behaviours were detected. The sample was composed of 364 students (206 boys and 158 girls) who were evaluated at their schools. Information about socio-demographic characteristics, Internet use habits, and online behaviours was collected using a data-gathering tool specifically designed for the study. The results demonstrated high Internet use by the adolescents studied. Girls used the Internet more for social relationships, whereas boys tended to use it differently, including accessing online games. Moreover, some risky behaviours were found, including interactions with strangers, giving out personal information, and sending photos and videos. Likewise, behaviours associated with «cyber-bullying» were detected. These results indicate the necessity of establishing prevention programs for safe and responsible Internet use.
En los últimos años se ha producido un aumento espectacular del uso de las nuevas tecnologías de la información y de la comunicación. En este estudio se analizaron las características y el patrón del uso de Internet en una muestra de preadolescentes de entre 10 y 13 años, que cursan 6º curso de Educación Primaria en Navarra (España). Asimismo, se analizó la existencia de un perfil diferencial en el uso de Internet en función del sexo y se detectó la existencia de conductas de riesgo. La muestra estaba compuesta por 364 estudiantes (206 chicos y 158 chicas), que fueron evaluados en sus centros educativos. Se recogió información sobre las características sociodemográficas, los hábitos de uso de Internet y los comportamientos desarrollados en la Red a través de un instrumento de recogida de datos diseñado específicamente para la investigación. Los resultados mostraron un uso elevado de Internet por parte de los adolescentes estudiados. Las chicas usaban más Internet para las relaciones sociales, mientras que los chicos tendían a darle otro tipo de usos, como el acceso a juegos online. Además, se encontraron algunas conductas de riesgo, como quedar con desconocidos, dar datos personales o enviar fotos y vídeos. Asimismo, se encontraron comportamientos relacionados con el «ciberbullying». Estos resultados indican la necesidad de establecer programas de prevención para el uso seguro y responsable de Internet.
Forms of Media Convergence and Multimedia Content – A Romanian Perspective
Authors: Drula Georgeta 
Published: October 2014

This paper addresses two types of technological media convergence: media convergence based on mobile technology, and also convergence based on the unification between IT and media industry. These forms are influenced by the multimedia aspects of the content. The research interest in this study is related to media landscape in Romania and its state. Even if many academics and practitioners consider media convergence only at the content level from journalistic perspective, this topic has many more detail aspects and trends. Thus, media convergence in terms of content can be now interpreted together with the user’s content and takes into consideration the unification between paid, owned, shared and earned content. This paper proposes a theoretical and practical perspective for the relationship between convergence and multimedia for online media products. This perspective belongs both to media producers and to online consumers of information. The paper is interesting in that it reveals the challenges facing the media industries, and shows approaches of convergence that are related to multimedia for media products. The methodological framework uses the content analysis and the hierarchical cluster analysis to discover different forms of convergence in online media. The main conclusion of this study shows that due to various technologies and their partnerships, convergence can be directed both from the users to the media industry, and conversely.
Este artículo se centra en dos tipos de convergencia tecnológica de medios: la basada en tecnología móvil, y la convergencia basada en la unificación de las tecnologías de la información y la industria mediática. Estas formas están influidas por los aspectos multimedia del contenido. El interés de la investigación de este estudio se centra en el panorama mediático en Rumanía y en su estado actual. Aunque muchos académicos y profesionales evalúan la convergencia de medios por el contenido desde una perspectiva periodística, existen otros muchos aspectos y tendencias a tener en cuenta. Así, la convergencia de medios en términos de contenido puede ser interpretada junto al contenido del usuario y considera la unificación del contenido pagado, poseído, compartido y adquirido. Este artículo propone una perspectiva teórica y práctica para la relación entre convergencia y multimedia en cuanto a los productos mediáticos on-line. Esta perspectiva se refiere a los productores y a los consumidores de la información. El interés del artículo reside en tanto que identifica los retos de la industria mediática y establece enfoques acerca de la convergencia multimedia para los productos mediáticos. La metodología consiste en el análisis de contenido y en el agrupamiento jerárquico con el objetivo de descubrir diferentes formas de convergencia de medios on-line. La conclusión establece que, gracias a varias tecnologías y sus asociaciones, la convergencia puede dirigirse desde el usuario a la industria y viceversa.

Published: October 2014

This work is part of an R&D project involving thirteen Spanish universities in which needs and wants in the field of media education in higher education are studied in the areas of Communication (Communication Studies, Journalism and Advertising) and Education (Teaching, Pedagogy, Psychology and Social Education). The objective of this study focuses on analysing the college textbooks directly related to Media Education most used in Education and Communication,. The report has been developed based on six educational competence dimensions: language, technology, interaction processes, production and distribution processes, ideology and values and aesthetics. Using each of these parameters the scope of the analysis and the scope of the expression were taken into account, based on guidelines set by Ferrés and Piscitelli in their well-known proposal of indicators for defining new media competence and which is structured around two areas of work: the production of own messages and interaction with others. The results were obtained by applying a quantitative methodology through a content analysis of semantic fields. The main conclusions point to a greater presence of the «Ideology and Values» dimension, and almost non-existent representation of the «Aesthetics» indicator.El presente trabajo forma parte de un proyecto I+D integrado por trece universidades españolas en el que se estudian las necesidades y carencias en materia de educación mediática en el ámbito de la enseñanza superior, tanto en las áreas de Comunicación (Comunicación Audiovisual, Periodismo y Publicidad) como de Educación (Magisterio, Pedagogía, Psicopedagogía y Educación Social). Esta investigación centra su objeto de estudio en el análisis de los manuales universitarios más utilizados en Educación y Comunicación, en asignaturas directamente relacionadas con la educación mediática. Este informe se ha desarrollado en base a seis dimensiones competenciales mediáticas: lenguajes, tecnología, procesos de interacción, procesos de producción y difusión, ideología y valores y estética. De cada uno de estos parámetros se ha tenido en cuenta el ámbito del análisis y de la expresión, partiendo de las pautas señaladas por Ferrés y Piscitelli en su conocida propuesta articulada de indicadores para definir la nueva competencia mediática, que se ha estructurado en torno a dos ámbitos de trabajo: el de la producción de mensajes propios y el de la interacción con otros ajenos. Los resultados han sido obtenidos mediante la aplicación de una metodología cuantitativa, a través de un análisis de contenido por campos semánticos. Las principales conclusiones extraídas apuntan hacia una mayor presencia de la dimensión Ideología y Valores, y una casi inexistente representación de la dimensión Estética.
Wavelet Entropy Algorithm to Allocate the Extreme Power Peaks in WiMax Systems
Authors: Daoud Omar , Hamarsheh Qadri , Saraireh Saleh 
Published: October 2014

This work proposes a solution to overcome the effect for one of the main drawbacks of these days’ wireless systems, where Multiple-Input Multiple-Output (MIMO)-Orthogonal Frequency Division Multiplexing (OFDM) combinations has been used. High peak-to-average power ratio (PAPR) arises after the OFDM stage and reduces the performance of the used nonlinear devices. Therefore, a new stage has been imposed between the MIMO and OFDM block. It is based on the entropy meaning of the wavelet transformation to trigger a proposed thresholding criterion and reconstruct the OFDM signal. As a result, the probability of high PAPR appearance will be limited and reduced; a promising result over our recently published work has been conducted; 15-25% extra reduction. This work could be denoted by MIMO-OFDM based on Entropy Wavelet Transform (MO-EWT) systems.
The MO-EWT validity has been checked based on either numerical analysis or conducted simulation based on MATLAB; where 80% improvement of reducing the high PAPR has been achieved over the literature. These results have been reached using the same environment conditions and at additional cost and complexity of the transceivers structure.

Abstract
Circulating monocytes carrying human CMV (HCMV) migrate into tissues, where they differentiate into HCMV-infected resident macrophages that upon interaction with bacterial products may potentiate tissue inflammation. In this study, we investigated the mechanism by which HCMV promotes macrophage-orchestrated inflammation using a clinical isolate of HCMV (TR) and macrophages derived from primary human monocytes. HCMV infection of the macrophages, which was associated with viral DNA replication, significantly enhanced TNF-α, IL-6, and IL-8 gene expression and protein production in response to TLR4 ligand (LPS) stimulation compared with mock-infected LPS-stimulated macrophages during a 6-d in vitro infection. HCMV infection also potentiated TLR5 ligand–stimulated cytokine production. To elucidate the mechanism by which HCMV infection potentiated inducible macrophage responses, we show that infection by HCMV promoted the maintenance of surface CD14 and TLR4 and TLR5, which declined over time in mock-infected macrophages, and enhanced both the intracellular expression of adaptor protein MyD88 and the inducible phosphorylation of IκBα and NF-κB. These findings provide additional information toward elucidating the mechanism by which HCMV potentiates bacteria-induced NF-κB–mediated macrophage inflammatory responses, thereby enhancing organ inflammation in HCMV-infected tissues.
