The ecocultural context and child behavior problems: A qualitative analysis in rural Nepal.

Commonly used paradigms for studying child psychopathology emphasize individual-level factors and often neglect the role of context in shaping risk and protective factors among children, families, and communities. To address this gap, we evaluated influences of ecocultural contextual factors on definitions, development of, and responses to child behavior problems and examined how contextual knowledge can inform culturally responsive interventions. We drew on Super and Harkness' "developmental niche" framework to evaluate the influences of physical and social settings, childcare customs and practices, and parental ethnotheories on the definitions, development of, and responses to child behavior problems in a community in rural Nepal. Data were collected between February and October 2014 through in-depth interviews with a purposive sampling strategy targeting parents (N = 10), teachers (N = 6), and community leaders (N = 8) familiar with child-rearing. Results were supplemented by focus group discussions with children (N = 9) and teachers (N = 8), pile-sort interviews with mothers (N = 8) of school-aged children, and direct observations in homes, schools, and community spaces. Behavior problems were largely defined in light of parents' socialization goals and role expectations for children. Certain physical settings and times were seen to carry greater risk for problematic behavior when children were unsupervised. Parents and other adults attempted to mitigate behavior problems by supervising them and their social interactions, providing for their physical needs, educating them, and through a shared verbal reminding strategy (samjhaune). The findings of our study illustrate the transactional nature of behavior problem development that involves context-specific goals, roles, and concerns that are likely to affect adults' interpretations and responses to children's behavior. Ultimately, employing a developmental niche framework will elucidate setting-specific risk and protective factors for culturally compelling intervention strategies.

Youth sport coaches’ reflections on leadership behaviours during games and practices

Youth sport coaches shape the developmental sporting experience for their athletes (Camiré, Trudel, & Forneris, 2014). Specifically, coaches who form individualized, supportive relationships with their athletes can increase the development of personal and social skills (Fraser-Thomas, Côté, & Deakin, 2005). In light of the value of these relationships, increasing evidence is prompting the application of leadership theories, such as Transformational Leadership (TFL), in youth sport (Vella et al., 2013). The aim of this study was to explore coach perceptions of how and why leadership behaviours are applied in the youth sport context. Eleven coaches (Mage= 42.3, SD= 15.2) were recruited from competitive youth soccer and volleyball clubs (athletes’ Mage= 15.8, SD= 1.9) in Eastern Ontario and participated in a stimulated recall interview. During the interviews, coaches reflected upon their own coaching behaviours and provided insight into the application of leadership behaviours in youth sport. Responses were prompted by relevant video sequences from recorded practice and game sessions. A thematic content analysis revealed that; i) coaches use a variety of leadership behaviours in youth sport, ii) the use of leadership behaviours vary across sport contexts or settings, and iii) contrasting leadership styles (e.g., transactional vs. transformational) are associated with distinctive coach objectives (e.g., promoting confidence vs. establishing respect). These findings have helped identify gaps within coach education, and provide theoretical insight for applying leadership theories, and more specifically TFL, to help improve the sport experiences of young athletes.

O Contrato Psicológico e a Influência do Tipo de Vínculo: empenhamento na carreira e commitment organizacional

As transformações nas relações contratuais e na ligação psicológica do indivíduo à organização motivaram a realização do presente estudo. Os seus objectivos centrais consistiram em, por um lado, analisar a influência do tipo de vínculo na formação do Contrato Psicológico dos indivíduos com a organização e, por outro lado, compreender a relação do Contrato Psicológico com o Empenhamento na Carreira e com o Commitment Organizacional, e o que poderá distinguir estas relações. A metodologia apoiou-se num questionário, aplicado a uma amostra de 102 profissionais com vínculos de trabalho estáveis e instáveis, de diferentes organizações, ramos profissionais e sectores de actividade. A amostra é proporcional e representativa. (a) Os resultados demonstram que os profissionais prestadores de serviço são o único caso em que o tipo de vínculo tem influência significativa sobre a formação do Contrato Psicológico, percepcionando uma ligação transaccional com a organização. (b) Em contrapartida, provam que uma maior ou menor estabilidade contratual não tem influência significativa sobre os Contratos Psicológicos relacional ou equilibrado. (c) Os resultados sugerem ainda que o Contrato Psicológico está mais directamente relacionado com o Empenhamento na Carreira do que com o Commitment Organizacional. O Contrato Psicológico apresenta correlações fortes com o Empenhamento na Carreira e a consequente utilização de comportamentos individuais de Gestão de Carreira, sendo esta mais significativa nas ligações psicológicas de tipo equilibrado e relacional. No que respeita ao Commitment Organizacional, este não apresenta relação significativa com o Contrato Psicológico mas verificamos a existência de focus de Commitment Organizacional. Os resultados comprovam que o Contrato Psicológico se correlaciona com a sua dimensão normativa. As conclusões evidenciam o incremento das relações transaccionais, motivadas pela menor durabilidade dos vínculos e o desenvolvimento de reduzidas expectativas na relação com a organização e para o carácter individual e circunstancial das ligações psicológicas, que já não obedecem a um padrão tipo. Perante cenários de grande instabilidade, independentemente do Contrato Psicológico estabelecido, a preocupação com a Carreira ganha relevância. Os profissionais actuais tendem a transferir a preocupação com o vínculo e a segurança no emprego para questões de carreira, segurança de empregabilidade e sucesso psicológico. Observa-se que a lealdade à organização é na maior parte dos casos transferida para a lealdade à carreira. / Transformations in contractual relationships and in the psychological connection of an individual to an organization have motivated the execution of the present study. The main objectives of this study were, on the one hand, to analyze the influence of the type of contractual bond in the shaping of the psychological contract of individuals with an organization, and, on the other hand, to understand the relationship between the psychological contract, the career commitment and the organizational commitment, to understand subsequently what may distinguish these relationships. The methodology was supported by a questionnaire, which was applied to a sample of 105 professionals with both stable and unstable contractual bonds in different organizations, professional lines of business and activity sectors. The sample is proportional and representative. (a) The results demonstrate that service providing professionals are the only case in which the type of contractual bond has a significant influence on the shaping of a psychological contract, perceived as a transactional connection with the organization. (b) On the other hand a higher or lower contractual stability has no significant influence or relationship with the psychological contract, relational or balanced. (c) The results also suggest that the psychological contract is more directly related to career commitment than to organizational commitment. The psychological contract shows a strong correlation with the career commitment and the consequent use of the individual behaviour of Career Management, with the latter being more significant to a balanced and relational type of psychological connection. In regard to Organizational Commitment, this presents no significant relationship with the psychological contract but the focus on the organizational commitment is verified. The results also show that the psychological contract is correlated with its normative dimension. The increase in transactional relationships are evident. This is driven by reduction of the durability of contractual bonds and the development of reduced expectations in relation to the organization and the individual character and circumstance of the psychological connections, which no longer conform to a standard type. Scenarios of great instability, regardless of the psychological contract established, cause the concern with career to gain relevance. Current professionals tend to transfer their concerns about contractual bonds and job security to career issues, job security and psychological success. It can also be seen that loyalty to the organization is, in most cases, transferred to loyalty to the career.

A formação e o desenvolvimento de arranjos cooperativos sob a ótica da imersão social e da economia dos custos de transação: um estrudo de caso na Coopercam e na Unipesca

The current study analyzes the birth and development of two strategic alliances established between shrimp producers in Rio Grande do Norte: the Unipesca and the Coopercam. To achieve this aim, two approaches which, at first sight, could be considered contradictory were used: the Transactional Costs Economy and Embeddedness. The first approach is fundamentally based in the studies of Williamson (1985; 1991; 1996; 1999; 2000; 2002). Embededness, on the other hand, went through the review of a series of authors, such as Burt (1992), Granovetter (1973; 1985), Uzzi (1997), Gulati (1994; 1995; 1997; 1998; 1999; 2000), Nielsen (2005), Ring (2002), Ring and Van de Ven (1994), Zafirovski (2002), among others. To analyze the birth and development of the cooperatives in this study, Gulati s work (1998) was used. This study shows the steps to be studied for a better comprehension of an alliance: the decision of starting an alliance and the choice of the partners, the decision about the governance structure, the evolution of the alliance and the development of the companies which established this partnership. To carry this study out, a study case accordingly to Yin s proposal (2001) was adopted. Semi-structured interviews with pre-defined plots were conducted in two phases: in the beginning of 2006 and in the beginning of 2007. The subjects from the research were, in 2006, representative members of the main associations and corporations, besides the shrimp producers from the state, when the context of the activity was set. In the second phase, in 2007, representative members from the two cooperatives that were listed above were interviewed the president from Coopercam and the marketing manager from Unipesca. Besides these two members, directors from two important organizations in each of these cooperatives were also interviewed, giving out the necessary information for the research. Secondary data was also collected from the Brazilian Association of Crab producers website, as well as from news from important newspapers in RN, such as Tribuna do Norte. The primary data was analyzed in terms of quality, accordingly to the documental analysis technique. Thus, through the data that was collected, it can be concluded that the reasons that motivated the companies to cooperate can be explained in terms of the transactional costs economy. However, the choice of partners is more connected to aspects approached by the social embededness. When aspects related to development and evolution were analyzed, it could be seen that both aspects from TCE and Embededness were vital to explain the development of the cooperatives mentioned

BUILDING EFFICIENT AND COST-EFFECTIVE CLOUD-BASED BIG DATA MANAGEMENT SYSTEMS

In today’s big data world, data is being produced in massive volumes, at great velocity and from a variety of different sources such as mobile devices, sensors, a plethora of small devices hooked to the internet (Internet of Things), social networks, communication networks and many others. Interactive querying and large-scale analytics are being increasingly used to derive value out of this big data. A large portion of this data is being stored and processed in the Cloud due the several advantages provided by the Cloud such as scalability, elasticity, availability, low cost of ownership and the overall economies of scale. There is thus, a growing need for large-scale cloud-based data management systems that can support real-time ingest, storage and processing of large volumes of heterogeneous data. However, in the pay-as-you-go Cloud environment, the cost of analytics can grow linearly with the time and resources required. Reducing the cost of data analytics in the Cloud thus remains a primary challenge. In my dissertation research, I have focused on building efficient and cost-effective cloud-based data management systems for different application domains that are predominant in cloud computing environments. In the first part of my dissertation, I address the problem of reducing the cost of transactional workloads on relational databases to support database-as-a-service in the Cloud. The primary challenges in supporting such workloads include choosing how to partition the data across a large number of machines, minimizing the number of distributed transactions, providing high data availability, and tolerating failures gracefully. I have designed, built and evaluated SWORD, an end-to-end scalable online transaction processing system, that utilizes workload-aware data placement and replication to minimize the number of distributed transactions that incorporates a suite of novel techniques to significantly reduce the overheads incurred both during the initial placement of data, and during query execution at runtime. In the second part of my dissertation, I focus on sampling-based progressive analytics as a means to reduce the cost of data analytics in the relational domain. Sampling has been traditionally used by data scientists to get progressive answers to complex analytical tasks over large volumes of data. Typically, this involves manually extracting samples of increasing data size (progressive samples) for exploratory querying. This provides the data scientists with user control, repeatable semantics, and result provenance. However, such solutions result in tedious workflows that preclude the reuse of work across samples. On the other hand, existing approximate query processing systems report early results, but do not offer the above benefits for complex ad-hoc queries. I propose a new progressive data-parallel computation framework, NOW!, that provides support for progressive analytics over big data. In particular, NOW! enables progressive relational (SQL) query support in the Cloud using unique progress semantics that allow efficient and deterministic query processing over samples providing meaningful early results and provenance to data scientists. NOW! enables the provision of early results using significantly fewer resources thereby enabling a substantial reduction in the cost incurred during such analytics. Finally, I propose NSCALE, a system for efficient and cost-effective complex analytics on large-scale graph-structured data in the Cloud. The system is based on the key observation that a wide range of complex analysis tasks over graph data require processing and reasoning about a large number of multi-hop neighborhoods or subgraphs in the graph; examples include ego network analysis, motif counting in biological networks, finding social circles in social networks, personalized recommendations, link prediction, etc. These tasks are not well served by existing vertex-centric graph processing frameworks whose computation and execution models limit the user program to directly access the state of a single vertex, resulting in high execution overheads. Further, the lack of support for extracting the relevant portions of the graph that are of interest to an analysis task and loading it onto distributed memory leads to poor scalability. NSCALE allows users to write programs at the level of neighborhoods or subgraphs rather than at the level of vertices, and to declaratively specify the subgraphs of interest. It enables the efficient distributed execution of these neighborhood-centric complex analysis tasks over largescale graphs, while minimizing resource consumption and communication cost, thereby substantially reducing the overall cost of graph data analytics in the Cloud. The results of our extensive experimental evaluation of these prototypes with several real-world data sets and applications validate the effectiveness of our techniques which provide orders-of-magnitude reductions in the overheads of distributed data querying and analysis in the Cloud.

Kim jestem? Kim się staję? W dialogicznym napięciu JA-TY. Źródła teoretyczne

W niniejszym artykule przedstawiono komponenty wchodzące w skład źródeł teoretycznych, będących podstawą powstania konspektu warsztatów. Treść artykułu nie wychodzi poza obszar metodologii teologicznej. Badania ukazujące przesłanki procesów zaaranżowanych w czasie warsztatów oraz podane wnioski końcowe wynikają z badań przeprowadzonych w polu analiz teologii fundamentalnej. Ta dziedzina teologiczna zakłada interdyscyplinarne łączenie metod i osiągnięć teologii i nauk antropologicznych. W kolejnych odsłonach ukazane zostały trzy aspekty odkrywania ludzkiego JA w dialogicznym napięciu z TY. Dzięki analizie transakcyjnej Erica Berne’a można ukazać, przy pomocy prostych technik edukacyjnych, że człowiek w poznaniu siebie potrzebuje drugiego w każdym aspekcie swego istnienia. Tym, co umożliwia mu bycie z sobą i innymi do zdolność wczucia. Tę kategorię badawczą analizowała Edyta Stein jako podstawę realnych relacji JA-TY, gdzie poprzez TY może zostać określony sam człowiek jako nie-ja, inny, drugi, czy ostatecznie osobowy Bóg. Możliwość zastosowania procesów opartych na wczuciu w przestrzeni relacji wiary doprowadza ku teologii duchowości. W jej ramach wypracowany został model antropologiczny, który widzi człowieka w ciągłym stawaniu się wobec innych i Boga. Przyjęta do badań praktyczno-biblijna antropologia Ignacego Loyoli pozwala na uwiarygodnienie kroków podjętych w czasie warsztatów, tak by nie były manipulacją a służyły wolnemu wyborowi uczestników w świadomym poszukiwaniu sensu i celu istnienia.

Fault tolerance logging-based model for deterministic systems

Fault tolerance allows a system to remain operational to some degree when some of its components fail. One of the most common fault tolerance mechanisms consists on logging the system state periodically, and recovering the system to a consistent state in the event of a failure. This paper describes a general fault tolerance logging-based mechanism, which can be layered over deterministic systems. Our proposal describes how a logging mechanism can recover the underlying system to a consistent state, even if an action or set of actions were interrupted mid-way, due to a server crash. We also propose different methods of storing the logging information, and describe how to deploy a fault tolerant master-slave cluster for information replication. We adapt our model to a previously proposed framework, which provided common relational features, like transactions with atomic, consistent, isolated and durable properties, to NoSQL database management systems.

Diseño e implementación de un sistema de soporte de decisiones para el Centro de Documentación Regional “Juan Bautista Vázquez”

El volumen de datos en bibliotecas ha aumentado enormemente en los últimos años, así como también la complejidad de sus fuentes y formatos de información, dificultando su gestión y acceso, especialmente como apoyo en la toma de decisiones. Sabiendo que una buena gestión de bibliotecas involucra la integración de indicadores estratégicos, la implementación de un Data Warehouse (DW), que gestione adecuadamente tal cantidad de información, así como su compleja mezcla de fuentes de datos, se convierte en una alternativa interesante a considerar. El artículo describe el diseño e implementación de un sistema de soporte de decisiones (DSS) basado en técnicas de DW para la biblioteca de la Universidad de Cuenca. Para esto, el estudio utiliza una metodología holística, propuesto por Siguenza-Guzman et al. (2014) para la evaluación integral de bibliotecas. Dicha metodología evalúa la colección y los servicios, incorporando importantes elementos para la gestión de bibliotecas, tales como: el desempeño de los servicios, el control de calidad, el uso de la colección y la interacción con el usuario. A partir de este análisis, se propone una arquitectura de DW que integra, procesa y almacena los datos. Finalmente, estos datos almacenados son analizados y visualizados a través de herramientas de procesamiento analítico en línea (OLAP). Las pruebas iniciales de implementación confirman la viabilidad y eficacia del enfoque propuesto, al integrar con éxito múltiples y heterogéneas fuentes y formatos de datos, facilitando que los directores de bibliotecas generen informes personalizados, e incluso permitiendo madurar los procesos transaccionales que diariamente se llevan a cabo.

The interaction factor as a challenge for foreign language learning in the technology based education: a pedagogical reflection

The author carries out a pedagogical reflection on how the technology driven distance learning repeatedly neglects the scientific achievements of Second Language Acquisition and Language Pedagogy. Seeing communicative competence as a major goal of a language classroom, she presents the main challenges that the communicative approach poses to distance learning. To this end, a general distance learning theory by Moore is adapted to the needs of language education, through a distinction between three aspects of learner interaction – with the teacher, with other learners and with content. In this three-dimensional paradigm the learner is seen as the main actor of the process, the teacher as a facilitator, the text as a main source of communicative data and the learner autonomy as the fundament of the process.

A liderança e a implementação do Plano Tecnológico de Educação nas escolas portuguesas

O Plano Tecnológico de Educação (PTE) pretendeu equipar tecnologicamente as escolas públicas de Portugal continental, procurando introduzir, por essa via, alterações e inovação no ensino e na aprendizagem. Neste contexto, importa destacar o papel que os coordenadores do PTE tiveram localmente, já que foram os responsáveis pela sua implementação dentro das escolas. Focámos assim a nossa investigação na figura dos CPTE, de forma a percebermos como o PTE tinha sido implementado e liderado nas escolas. Partimos de um enquadramento do problema, perspetivado em torno de três temas: a construção do Plano Tecnológico de Educação, destacando os seus três eixos e projetos, a problemática da incorporação das tecnologias de informação e comunicação na educação e o papel da liderança em projetos de inovação e mudança. O estudo empírico realizado apoiou-se fundamentalmente em métodos quantitativos, complementado por elementos qualitativos. Foi aplicado um inquérito a uma amostra com representação nacional, de 100 CPTE, de agrupamentos de escolas e escolas não agrupadas de Portugal continental com ensino secundário. Este inquérito permitiu perceber quem foram estes coordenadores ao definirmos o seu perfil relativamente às suas características pessoais e profissionais, às suas competências nas dimensões previstas para a função, bem como à sua liderança, neste caso concreto através da utilização do MLQ, de Bass & Avolio. Permitiu ainda determinar as condições de implementação do PTE e os principais constrangimentos. Os resultados obtidos comprovaram que nem todos os objetivos inicialmente propostos para o PTE foram concluídos ou implementados. No entanto, o balanço a nível tecnológico e de gestão é bastante positivo e menos a nível pedagógico. A liderança desempenhada pela generalidade dos CPTE enquadrou-se no perfil ideal identificado por Avolio & Bass (1995), onde as características de liderança transformacional são as mais manifestadas, complementando-se com algumas de liderança transacional.
