Música reggae y modulaciones sociales: notas acerca de la relación individuo-grupo en una isla caribeña
Authors: Sánchez Aguirre Rafael Andrés 
Published: April 2016

<p>La relación individuo-grupo es un tema central en diversos ámbitos del conocimiento; asunto que también resulta relevante en el campo musical. En este escrito, se asume que la musicalidad individual está ligada estructuralmente ―más no agotada― a una musicalidad social e histórica. De tal forma, se intenta sugerir algunas líneas de reflexión acerca de la práctica de la música <em>reggae </em>en una isla del Caribe. El análisis de este fenómeno musical permitirá reconocer dimensiones de colectividad que los músicos y miembros de la comunidad van tejiendo. Se ha realizado un ejercicio de carácter sociológico, etnográfico y de revisión histórica, para detallar discrepancias sonoras, síncopas sociales y resistencias culturales que fortalecen sentidos de acción colectiva.</p>
Estimación de observaciones faltantes en series de tiempo usando métodos multivariados con restricciones
Authors: Velásquez Gallo María Ana , Martínez Collantes Jorge 
Published: April 2016

Para tener éxito en el modelamiento de cualquier fenómeno físico, es importante disponer de una fuente de información completa. En este documento se plantea la reconstrucción o estimación de observaciones faltantes en series de tiempo múltiples, siguiendo la metodología de Guerrero (1989) de pronósticos con restricciones, las cuales vienen dadas por información adicional relacionada con el modelo que tiene en cuenta su información histórica y su estructura de correlación, minimizando el error cuadrático medio, y asumiendo además, que no se presentó un cambio de estructura en el segmento faltante, lo cual se verifica mediante una prueba de bondad de ajuste. El pronóstico óptimo se restringe a conservar la estructura inicialmente identificada, de manera que empalmen los pronósticos obtenidos con la información posterior disponible, y con esto, no se vean afectados los parámetros, la parte estocástica y la parte determinística del modelo.

Practice-Based Quality Improvement Collaborative to Increase Chlamydia Screening in Young Women
Authors: DiVasta Amy D. , Trudell Emily K. , Francis Mary , Focht Glenn , Jooma Farah , Vernacchio Louis , Forman Sara F. 
Published: April 2016

BACKGROUND AND OBJECTIVE:
Chlamydia trachomatis infections are common among sexually active young women. We developed a practice-based quality improvement (QI) collaborative to increase Chlamydia screening in at-risk young women.

METHODS:
Structured data fields were integrated into the electronic record for practices affiliated with Boston Children’s Hospital. A learning community (LC) was developed. Content included the adolescent well visit, assessment of sexual/risk behaviors, epidemiology of sexually transmitted diseases, and screening methods. The QI initiative effectiveness was assessed by comparing preintervention and postintervention rates of Chlamydia screening by using statistical process control analyses and logistic regressions.

RESULTS:
LC participants demonstrated significant increases in recommended Chlamydia screening, as illustrated by using Healthcare Effectiveness Data and Information Set (HEDIS) screening rates (LC1: 52.8% preintervention vs 66.7% postintervention [P &lt; .0001]; LC2: 57.8% preintervention vs 69.3% postintervention [P &lt; .0001]). Participating practices reported total improvements larger than nonparticipating practices (13.9% LC1, 11.5% LC2, and 7.8% nonparticipants). QI and LC efforts also led to increased documentation of sexual activity status in the record (LC1: 61.2% preintervention to 91.2% postintervention [P &lt; .0001]; LC2: 43.3% preintervention to 61.2% postintervention [P &lt; .0001]). Nonparticipating practices were more likely to perform indiscriminate screening.

CONCLUSIONS:
Through our QI and LC efforts, statistically and clinically meaningful improvements in Chlamydia screening rates were attained. Differences in rates of improvement indicate that LC participation likely had effects beyond electronic medical record changes alone. During the project time frame, national HEDIS screening rates remained unchanged, suggesting that the observed improvements were related to the interventions and not to a national trend. As a result of QI tools provided through the LCs, HEDIS screening goals were achieved in a primary care setting.
Cognitive Behavioral Therapy in Primary Care for Youth Declining Antidepressants: A Randomized Trial
Authors: Clarke Gregory , DeBar Lynn L. , Pearson John A. , Dickerson John F. , Lynch Frances L. , Gullion Christina M. , Leo Michael C. 
Published: April 2016

BACKGROUND AND OBJECTIVE:
Health care providers have few alternatives for youth depression other than antidepressants. We examined whether brief cognitive behavioral therapy (CBT) is a viable alternative in primary care.

METHODS:
A total of 212 adolescents aged 12 to 18 with major depression who had recently declined or quickly discontinued new antidepressant treatment were randomized to self-selected treatment as usual (TAU) control condition or TAU plus brief individual CBT. Blinded evaluators followed youth for 2 years. The primary outcome was time to major depression diagnostic recovery.

RESULTS:
CBT was superior to the control condition on the primary outcome of time to diagnostic recovery from major depression, with number needed to treat from 4 to 10 across follow-up. A similar CBT advantage was found for time to depression diagnosis response, with number needed to treat of 5 to 50 across time points. We observed a significant advantage for CBT on many secondary outcomes over the first year of follow-up but not the second year. Cohen’s d effect sizes for significant continuous measures ranged from 0.28 to 0.44, in the small to medium effect range. Most TAU health care services did not differ across conditions, except for psychiatric hospitalizations, which occurred at a significantly higher rate in the control condition through the first year of follow-up.

CONCLUSIONS:
Observed results were consistent with recent meta-analyses of CBT for youth depression. The initial year of CBT superiority imparted an important clinical benefit and may reduce the risk of future recurrent depression episodes.
Performance of multiobjective computational intelligence algorithms for the routing and wavelength assignment problem
Authors: Patiño Jorge , Montes Bryan , Puerto Gustavo 
Published: April 2016

<p>This paper presents an evaluation performance of computational intelligence algorithms based on the multiobjective theory for the solution of the Routing and Wavelength Assignment problem (RWA) in optical networks. The study evaluates the Firefly Algorithm, the Differential Evolutionary Algorithm, the Simulated Annealing Algorithm and two versions of the Particle Swarm Optimization algorithm. The paper provides a description of the multiobjective algorithms; then, an evaluation based on the performance provided by the multiobjective algorithms versus mono-objective approaches when dealing with different traffic loads, different numberof wavelengths and wavelength conversion process over the NSFNet topology is presented. Simulation results show that monoobjective algorithms properly solve the RWA problem for low values of data traffic and low number of wavelengths. However, the multiobjective approaches adapt better to online traffic when the number of wavelengths available in the network increases as well as when wavelength conversion is implemented in the nodes.</p>
RESPONSABILIDAD SOCIAL DE LAS FUNDACIONES, Y EL GÉNERO EN SUS PATRONATOS
Authors: Rodríguez Silva Tamara , Pérez Carrillo Elena Fátima 
Published: April 2016

Las fundaciones son frecuentemente consideradas paradigmas del ejercicio de la responsabilidad empresarial de las empresas que las fundan, para desarrollar actividades de corte social, ambiental, etc. Son generalmente clasificadas em el sector de las Organizaciones sin Lucro. No obstante, en su propia configuración interna es frecuente identificar prácticas que no son siempre coherentes con una actitud socialmente responsable. Ejemplo de ello es la proporción del género menos representado, las mujeres, en los patronatos de algunas de las principales fundaciones de España. Existen actualmente propuestas para potenciar la igualdad en el ámbito de las grandes empresas societarias y mercantiles. Sorprende que no se hayan desarrollado iniciativas claras a ese respecto en el terreno de las fundaciones. Combinando técnicas propias de las ciencias de la información, con otras relacionadas con el derecho, propondremos vías para avanzar en la Responsabilidad Social Corporativa (RSC) interna de las fundaciones, en su perspectivas de ejercicio del poder y equilíbrio de géneros.
The Concept and Content of Teacher’s Reflective Practice: From Impulsiveness of Professional Activity towards Personal and Professional Development
Authors: Bubnys Remigijus , Kairienė Aida 
Published: April 2016

Reflective practice as one of the key factors determining changes in the teacher’s performance in a learning organization requires a careful study, focusing on aspects of creation of favourable learning environment at school. In order to analyse the concept of the teacher’s reflective practice, it is relevant to answer this problem question: How is the teacher’s reflective practice characterized and what is its content?
The research aim is to analyse the concept of reflective practice in the pedagogical context, distinguishing essential characteristics of the concept: attributes, antecedents, consequences. The research method is a systematic analysis of literature, using Rodgers’ (1989) method of evolutionary concept analysis. The theoretical analysis of the teacher’s reflective practice enabled to distinguish features that are directly associated with experiential learning, deep critical thinking, investigation of personal actions, professional and personal development. The disclosed antecedents of the concept are: reflection on experience, endeavour of reflection and the need to evaluate thinking and investigate one’s professional actions, endeavour of self-efficacy, knowledge and awareness, and the needs of improvement of teaching and learning, professional growth and renewal, personal integrity. Outcomes of the teacher’s professional and personal development were formulated. Research results enable to generalise that the teacher’s reflective practice is a complex concept, encompassing dimensions of experiential learning, critical thinking, reflective teaching / learning and investigation, related to the teacher’s professional and personal development.
The Dynamics of Values among Future Sport Pedagogues in the Last Decade
Authors: Malinauskas Romualdas 
Published: April 2016

The problem of this research can be defined by the following research question: what is the dynamics of values held by future sport pedagogues in the last decade? The study in 2004 documented number characteristics of values among future sport pedagogues. The study conducted in 2014 aimed to answer the question of whether the changing social environment and educational reform in the last decade is related to the future sports pedagogues’ values change.
It was presumed that students in 2004 and students in 2014 have different values. Three surveys used were the Rokeach Value Survey for identification of the most important personal values, Leontiev Life Meaning Orientations Test for the evaluation of values pertaining to the meaning of life (defined as ideas about life goals, processes, results and control of life circumstances), Sniras Moral Value Survey for identification of the most important moral values. Not the same first year students were investigated twice: the first time in the year 2004 (N = 168) and the second time in the year 2014 (N = 163).
The research findings revealed that ‘material well-being’ (financially secure lifestyle) and ‘public recognition’ (respect and authority) were the most important values among future sport pedagogues in the year 2004 compared to them in year 2014. ‘Clear life goals’ was the value pertaining to the meaning of life that was most significant to future sport pedagogues in 2014 compared to them in 2004. Forgiveness (not to diminish, not to revenge) was a significantly less important value for the first-year future sport pedagogues in 2014 than it was for them in year 2004.
‘Tech FTW!!!’ Ninth Graders, Romeo and Juliet, and Digital Technologies
Authors: Hammett Roberta 
Published: April 2016

This article describes an action research study in which ninth graders composed digital responses to their study of Shakespeare’s Romeo and Juliet. Their collaborative digital projects included e-zines, presentations, digital videos and photostories. Although meeting face to face in and outside of class, the students also used Ning (a social networking site) to share their products and to communicate about them throughout the unit. The paper will focus on what their communications reveal about the students’ participation and understanding during the composing process, including thinking, representing, actively engaged, creating, knowing, and social - summed up in the acronym TRACKS.

Teaching composition with new literacies perspectives: “We’ll test it out and then let the kids run with it.”
Authors: Kedersha McClay Jill , Stagg Peterson Shelley 
Published: April 2016

We report on two studies of teaching composition in Canadian elementary and middle-level classrooms, focusing this paper on teachers who work with new literacies perspectives. A study of 21 teachers in all 10 Canadian provinces provided evidence of a broad range of practices in composition instruction, and an ongoing action research study with two groups of teachers allows us to develop richer understandings of the ways in which teachers create curriculum with students to promote engaged and productive multimodal and digital composing practices. Nine themes are discussed within two broad categories: administrative and organizational issues, and teachers’ stances and views of selves as learners and collaborators.

<p>Physical characteristic of meat is very important in processing since it will determine the quality and type of processing being made. Meat characteristics of each livestock may different, but it is thought to be the same. Society in general assess the characteristics of buffalo and lamb meat with reference to the characteristics of beef, so that the processing of meat into processed meat products often have different outcomes. The aim of the experiment was to study<br />the physical characteristic (pH, water holding capasity, tenderness, and cooking loss) of beef, buffalo meat and lamb kept at the different by postmortem periods. The design used in experiment was a completely randomized design with<br />factorial pattern 2x3. The treatments were was postmortem periods (4 and 6 hours) and difference in kind of meat (beef, buffalo meat and lamb). The data was analysed by analysis of variance, and continued by Tukey test for<br />significant value. The results showed that the kind of meat had a significant effect (P&lt;0.05) on pH, water holding capacity, tenderness and cooking loss, while postmortem had significant effect (P&lt;0.05) on pH and water holding<br />capacity. The mean pH value of buffalo meat (6.05±0.36) was significantly (P&lt;0.05) higher than pH value of beef (5.70±0.20) and lamb (5.99±0.11). The mean water holding capacity of beef was significantly (P&lt;0.05) higher than<br />buffalo meat and lamb. The mean shear force of beef (6.73±0.16 kg/cm2) and buffalo meat (6.53±0.38 kg/cm2) were significantly (P&lt;0.05) higher than lamb (5.24±0.93 kg/cm2).</p><p>(Key words: Physical characteristic, Postmortem, Beef, Buffalo, and Lamb meat)<br /><br /></p>
