Analyzing the learning of the taking personal and social responsibility model within a new physical education undergraduate degree program in El Salvador

EI Salvador presents an unfortunate history that includes a military regime and a civil war that together created a legacy of violence in which the country still struggle nowadays. Salud Escolar Integral (SEI) was created in 2005 as a program to combat youth violence throughout the re-formulation of physical education (PE) classes in public schools, promoting life skills learning that supports the resolution of conflicts with nonviolent ways. In 2007, SEI supported the creation of a physical e~ucation teacher education (PETE) degree at the Universidad Pedag6gica de EI Salvador (UPES), having the goal to assist pre-service teachers with a better understanding of humanistic principles. The present research analyzed if after attending all three years ofUPES PETE program, students presented high self-perception levels of competence and confidence related to attitude, skills and knowledge to teach PE within humanistic principles. Taking Personal and Social Responsibility (TPSR) was the theoretical framework used to analyze the development of humanistic principles. The study had a mixed-method longitudinal design that included questionnaires, reflection templates and interviews. In conclusion, although it is suggested that UPES should provide better support for the development of the teaching principles of empowering students and transfer learning, most of the humanistic principles were highly promoted by the program. At last, it is suggested that future research should track teachers' progress while teaching in schools, in order to analyze if the theory of promoting humanistic principles have also become a daily practice.

The expression and development of teachers' capacities within two learning communities : a participant-observer case study

The learning community model has been an integral component of teacher development in Ontarian schools and beyond. This research was conducted to understand how teachers' personal capacity and professional, interpersonal, and organizational competencies are developed and expressed within this context. Nineteen elementary teachers and administrators participated in the study from November through January 2007. A qualitative case study methodology was used to investigate the role ofteachers' capacities and competencies in learning communities. Combined data sources from semistructured interviews, research journals, and document review were used to gather data about teachers' capacities and competencies. The study included 3 phases of analysis. In the final phase the analysis provided 3 qualities of the teachers at Jude and Mountain Schools (pseudonyms): identification as professionals, investment in others, and institutional affiliation that may explain how they differed from other educators. The data revealed these three themes, which provided an understanding of educators at Jude and Mountain Schools as dedicated professionals pushing practices to contribute to school life and address student learning needs, and as teachers who reflected on practices to continue expanding their skills. Teachers were heavily invested in creating a caring culture and in students' and team members' learning. Educators actively participated in solving problems and coplanning throughout the school levels and beyond, assumed collective responsibility for all pupils, and focused on generating school-wide consistent practices. These qualities and action patterns revealed teachers who invested time and effort in their colleagues, who committed to develop as professionals, and who affiliated closely with every aspect of school living.

Isoflavone exposure throughout suckling results in improved adult bone health in mice

Exposure to isoflavones (ISO), abundant in soy protein infant formula, for the first 5 days of life results in higher bone mineral density (BMD),greater trabecular connectivity and higher fracture load of lumbar vertebrae (LV) at adulthood. The effect of lengthening the duration of exposure to ISO on bone development has not been studied. This study determined if providing ISO for the first 21 days of life, which more closely mimics the duration that infants are fed soy protein formula, results in higher BMD, improved bone structure and greater strength in femurs and LV than a 5-day protocol. Female CD-1 mice were randomized to subcutaneous injections of ISO (7 Q1 mg kg/body weight/day) or corn oil from postnatal day 1 to 21. BMD, structure and strength were measured at the femur and LV at 4 months of age, representing young Q2 adulthood. At the LV, exposure to ISO resulted in higher (P,0.05) BMD, trabecular connectivity and fracture load compared with control (CON). Exposure to ISO also resulted in higher (P,0.05) whole femur BMD, higher (P,0.05) bone volume/total volume and Q3 lower (P,0.05) trabecular separation at the femur neck, as well as greater (P,0.05) fracture load at femur midpoint and femur neck compared with the CON group. Exposure to ISO throughout suckling has favorable effects on LV outcomes, and, unlike previous studies using 5-day exposure to ISO, femur outcomes are also improved. Duration of exposure should be considered when using the CD-1 mouse to model the effect of early life exposure of infants to ISO.

Le développement positif des jeunes en contexte sportif parascolaire : évaluation du programme d’intervention psychosociale Bien dans mes Baskets

L’objectif général de cette thèse était d’explorer le développement personnel de jeunes à risque de délinquance et de décrochage scolaire à travers leur participation à un programme d’intervention psychosociale nommé « Bien dans mes Baskets » (BdmB). Ce programme utilise le basketball parascolaire comme outil d’intervention et il a comme particularité qu’une bonne partie de ses entraineurs-intervenants détiennent une formation professionnelle en travail social ou domaines connexes. Cette thèse présente les résultats de trois études faisant partie d’un projet de recherche plus vaste portant sur l’évaluation du programme BdmB. Une première étude a exploré le processus de transfert, à d’autres domaines d’activités, des habiletés de vie ciblées par le programme BdmB. Des entretiens semi-directifs ont été réalisés auprès de 14 anciens participants et sept anciennes participantes du programme. Nos résultats suggèrent que trois principaux facteurs semblent avoir joué un rôle dans le processus de transfert des habiletés de vie développées au sein de BdmB, soit la présence de contextes favorisant l’apprentissage expérientiel, la valeur relative accordée aux différents domaines d’activités et la trajectoire de vie. Il ressort également de nos données qu’au-delà du processus de transfert sur une base individuelle, il est possible qu’un transfert puisse s’opérer dans la communauté. L’objectif de la deuxième étude était d’explorer comment et dans quelle mesure les expériences au sein de BdmB ont pu servir de levier au processus d’empowerment. Des entretiens semi-directifs ont été réalisés auprès de sept anciennes participantes de BdmB. Nos résultats suggèrent que la pratique sportive, combinée à une intervention psychosociale, peut contribuer au développement d’un plus grand contrôle sur sa vie. Cette amélioration serait la résultante cumulative de divers apprentissages, dont le développement et le transfert d’habiletés de vie et la capacité à résister aux influences externes négatives présentes dans leurs milieux de vie respectifs, ainsi que l’impact positif des expériences vécues au sein de BdmB sur la persévérance scolaire et les aspirations professionnelles. Une troisième étude avait pour objectif d’évaluer l’impact du programme BdmB sur le sentiment d’appartenance à l’école et la perception de soutien social. Un devis quasi expérimental a été utilisé pour évaluer l’impact du programme auprès des athlètes-étudiants(es) actuels. Le groupe d’intervention était composé des athlètes-étudiants de BdmB et les groupes de comparaison étaient constitués des étudiants de la même école ne participant pas au programme et pratiquant ou non un autre sport. Les individus ont été sondés à deux reprises à l’aide d’un questionnaire auto administré sur une période de deux années scolaires. Les résultats de l’étude indiquent que le groupe BdmB a développé un meilleur sentiment d’appartenance et a perçu un meilleur soutien social par rapport aux groupes de comparaison.

Enlarging a training set for genomic selction by imputation of un-genotyped animals in populations of varying genetic architecture

Background: The most common application of imputation is to infer genotypes of a high-density panel of markers on animals that are genotyped for a low-density panel. However, the increase in accuracy of genomic predictions resulting from an increase in the number of markers tends to reach a plateau beyond a certain density. Another application of imputation is to increase the size of the training set with un-genotyped animals. This strategy can be particularly successful when a set of closely related individuals are genotyped. ----- Methods: Imputation on completely un-genotyped dams was performed using known genotypes from the sire of each dam, one offspring and the offspring’s sire. Two methods were applied based on either allele or haplotype frequencies to infer genotypes at ambiguous loci. Results of these methods and of two available software packages were compared. Quality of imputation under different population structures was assessed. The impact of using imputed dams to enlarge training sets on the accuracy of genomic predictions was evaluated for different populations, heritabilities and sizes of training sets. ----- Results: Imputation accuracy ranged from 0.52 to 0.93 depending on the population structure and the method used. The method that used allele frequencies performed better than the method based on haplotype frequencies. Accuracy of imputation was higher for populations with higher levels of linkage disequilibrium and with larger proportions of markers with more extreme allele frequencies. Inclusion of imputed dams in the training set increased the accuracy of genomic predictions. Gains in accuracy ranged from close to zero to 37.14%, depending on the simulated scenario. Generally, the larger the accuracy already obtained with the genotyped training set, the lower the increase in accuracy achieved by adding imputed dams. ----- Conclusions: Whenever a reference population resembling the family configuration considered here is available, imputation can be used to achieve an extra increase in accuracy of genomic predictions by enlarging the training set with completely un-genotyped dams. This strategy was shown to be particularly useful for populations with lower levels of linkage disequilibrium, for genomic selection on traits with low heritability, and for species or breeds for which the size of the reference population is limited.

La incidencia de la complejidad en el ambiente organizacional

La realidad de la complejidad en las organizaciones actuales " Kellert: Hay que ver la teoría del caos como una nueva y revolucionaria ciencia que es discontinua radicalmente con la tradición occidental de objetivar y controlar la naturaleza pues falsifica tanto el carácter de la teoría del caos y la historia de la ciencia. ... cualquier expectativa de que la teoría del caos es el re-encantamiento del mundo se reunirá con la decepción“ La complejidad a lo largo de la segunda mitad del siglo XX, fue adquiriendo importancia a partir de los trabajos desarrollados desde diferentes disciplinas, como respuesta a los vertiginosos avances y a la aparición de nuevas tecnologías que están cambiando nuestra forma de vida y generando nuevo conocimiento. Estamos acostumbrados a ver el mundo de manera lineal, conforme a nuestras formación racionalista, y el ser humano desligado de la naturaleza y su proceso evolutivo, en ese sentido desde la aparición de las TCP, encontramos nuevas formas de entender, tanto los sistemas físicos, biológicos como los sociales humanos. El objetivo de este escrito e hipótesis es plantear la contradicción que se presenta al interior de las organizaciones desde el punto de vista de la realidad organizacional, realizando una mirada rápida al desarrollo las teorías que hoy en día componen lo que entendemos como complejidad, para terminar en el planteamiento de cómo ella se presenta en el interior de las organizaciones. En donde la toma de decisiones por la magnitud de información existe, se vuelven complejas y terminamos en la búsqueda de modelos que nos permitan un manejo adecuado de las organizaciones.

Liderazgo de Rango Total: revisión teórica del modelo

En el ámbito organizacional es necesario interiorizar y aplicar conceptos que generen herramientas que hagan posible el adecuado funcionamiento de las empresas a efectos de generar mejores resultados, no sólo en términos monetarios sino también sociales y éticos. En la actualidad, el entendimiento de las situaciones, circunstancias y relaciones que se dan dentro de una empresa es un factor relevante para la implementación de estrategias y técnicas, en aras de aumentar la productividad y la eficiencia de las compañías. Es allí donde empieza a tomar importancia la presencia de un líder en la compañía que actúe como agente de cambio y sea considerado como un modelo a seguir capaz de enfrentar situaciones emergentes, tanto positivas como negativas y así generar un cambio, deseos de mejora, propuestas inspiradoras e innovadoras. Lo anterior con el fin de proponer nuevas estrategias que beneficien a todos los involucrados, para así lograr los objetivos proyectados, evitando al máximo los posibles riesgos en que se pueda incurrir. A lo largo de la revisión teórica se tratará el modelo del liderazgo de rango total como un tipo de liderazgo donde el líder es capaz de moldear los puntos de vista, las percepciones, las actitudes y las creencias de los seguidores. Lo anterior sin dejar a un lado los demás estilos de liderazgo que componen el modelo de liderazgo de rango total, el cual puede ser considerado e incluido como una variable interesante en la realización de estudios para analizar la existencia de la relación entre el estilo de liderazgo y los resultados organizacionales.

Dimensões do êxito de egressos de escolas públicas no processo seletivo para o cursos de medicina da UFPE

Garantir a oferta de uma educação de qualidade nas escolas públicas de estados e municípios é um grande desafio a ser enfrentado pelo Brasil. Em se tratando da aprovação nos vestibulares para cursos superiores prestigiados socialmente, o êxito de egressos dessas instituições é difícil em qualquer universidade. Esta investigação, de natureza qualitativa articula dados quantitativos para fundamentar as discussões acerca dos fatores que explicam a aprovação desses estudantes no processo seletivo para o curso de medicina da Universidade Federal de Pernambuco [UFPE]. A fim de se realizar o estudo de caso em questão, utilizamos três instrumentos de recolha: o questionário, contendo informações pessoais e dados da formação educacional dos três egressos e de seus familiares; a entrevista semiestruturada, onde os três estudantes e seus pais tiveram a possibilidade de discorrer sobre os temas propostos; e a história de vida, através da qual um dos sujeitos retratou todo o conjunto da experiência vivida. Todo o material foi comparado e relacionado durante a análise por meio da triangulação de dados. Os nossos resultados confirmam os achados de outros trabalhos do gênero quando apontam que melhorar a qualidade da Educação Básica é essencial para que o Brasil avance na formação de mão de obra, mas, diferencia-se de alguns deles, quando sugere que, em relação aos candidatos que tentam ingressar no curso de medicina, tão importantes quanto o interesse e a mobilização do estudante e de seus pais em relação aos estudos são os investimentos em serviços de apoio pedagógico e psicológico, tanto aqueles prestados pelas escolas quanto os que são realizados em locais especializados [dependendo do caso].

O papel da liderança na promoção de uma dinâmica de escola aprendente- um projeto em desenvolvimento

A época atual exige que a escola se reformule e se adapte às exigências locais, nacionais e mundiais com as quais se confronta. O professor, ator principal das mudanças requeridas, vê aumentar significativamente as suas funções, necessitando de uma formação que corresponda às suas necessidades e que terá de efetivar ao longo de toda a sua vida profissional. Contudo, a formação proposta pelos centros de formação nem sempre se afigura a mais adequada. Para mudar, a escola precisa de lideranças fortes que apostem numa formação que vá ao encontro das necessidades sentidas e tente dar respostas eficazes. Tendo por base estes pressupostos, o presente projeto pretende investigar, no contexto particular de uma determinada escola, o modo como a(s) lideranças promovem uma dinâmica de escola aprendente e dinamizam formações que correspondam às necessidades sentidas. Este estudo permite-nos concluir que a(s) liderança(s) é um dos fatores que influencia fortemente o plano de formação, muito embora não seja o único. O entendimento que a(s) lideranças têm da formação, do desenvolvimento profissional e do futuro da escola, condiciona fortemente a dinâmica de escola que aprende. Decorrente da visão sobre a formação na escola alvo deste estudo, construiu-se um plano de ação de formação que assenta na criação de uma equipa de formação, team-teaching, centrada na escola, trabalhando colaborativamente, para dar início ao que poderá ser a solução para o problema identificado: uma formação que responda efetivamente e eficazmente às necessidades de formação dos professores da escola para fazer face às exigências da escola atual. Assim, partindo do team-teaching no departamento de línguas, tentar-se-á alargar a experiência e criar as bases para uma formação que promova a dinâmica de escola aprendente.

The counter-propagating Rossby-wave perspective on baroclinic instability. Part IV: Nonlinear life cycles

Pairs of counter-propagating Rossby waves (CRWs) can be used to describe baroclinic instability in linearized primitive-equation dynamics, employing simple propagation and interaction mechanisms at only two locations in the meridional plane—the CRW ‘home-bases’. Here, it is shown how some CRW properties are remarkably robust as a growing baroclinic wave develops nonlinearly. For example, the phase difference between upper-level and lower-level waves in potential-vorticity contours, defined initially at the home-bases of the CRWs, remains almost constant throughout baroclinic wave life cycles, despite the occurrence of frontogenesis and Rossby-wave breaking. As the lower wave saturates nonlinearly the whole baroclinic wave changes phase speed from that of the normal mode to that of the self-induced phase speed of the upper CRW. On zonal jets without surface meridional shear, this must always act to slow the baroclinic wave. The direction of wave breaking when a basic state has surface meridional shear can be anticipated because the displacement structures of CRWs tend to be coherent along surfaces of constant basic-state angular velocity, U. This results in up-gradient horizontal momentum fluxes for baroclinically growing disturbances. The momentum flux acts to shift the jet meridionally in the direction of the increasing surface U, so that the upper CRW breaks in the same direction as occurred at low levels

Fast training of self organizing maps for the visual exploration of molecular compounds

Visual exploration of scientific data in life science area is a growing research field due to the large amount of available data. The Kohonen’s Self Organizing Map (SOM) is a widely used tool for visualization of multidimensional data. In this paper we present a fast learning algorithm for SOMs that uses a simulated annealing method to adapt the learning parameters. The algorithm has been adopted in a data analysis framework for the generation of similarity maps. Such maps provide an effective tool for the visual exploration of large and multi-dimensional input spaces. The approach has been applied to data generated during the High Throughput Screening of molecular compounds; the generated maps allow a visual exploration of molecules with similar topological properties. The experimental analysis on real world data from the National Cancer Institute shows the speed up of the proposed SOM training process in comparison to a traditional approach. The resulting visual landscape groups molecules with similar chemical properties in densely connected regions.

Ecological and life-history traits predict bee species responses to environmental disturbances

The ability to predict the responses of ecological communities and individual species to human-induced environmental change remains a key issue for ecologists and conservation managers alike. Responses are often variable among species within groups making general predictions difficult. One option is to include ecological trait information that might help to disentangle patterns of response and also provide greater understanding of how particular traits link whole clades to their environment. Although this ‘‘trait-guild” approach has been used for single disturbances, the importance of particular traits on general responses to multiple disturbances has not been explored. We used a mixed model analysis of 19 data sets from throughout the world to test the effect of ecological and life-history traits on the responses of bee species to different types of anthropogenic environmental change. These changes included habitat loss, fragmentation, agricultural intensification, pesticides and fire. Individual traits significantly affected bee species responses to different disturbances and several traits were broadly predictive among multiple disturbances. The location of nests – above vs. below ground – significantly affected response to habitat loss, agricultural intensification, tillage regime (within agriculture) and fire. Species that nested above ground were on average more negatively affected by isolation from natural habitat and intensive agricultural land use than were species nesting below ground. In contrast below-ground-nesting species were more negatively affected by tilling than were above-ground nesters. The response of different nesting guilds to fire depended on the time since the burn. Social bee species were more strongly affected by isolation from natural habitat and pesticides than were solitary bee species. Surprisingly, body size did not consistently affect species responses, despite its importance in determining many aspects of individuals’ interaction with their environment. Although synergistic interactions among traits remain to be explored, individual traits can be useful in predicting and understanding responses of related species to global change.
