El estudio examinó la influencia de la inducción de la orientación de meta de una tarea en los resultados del trabajo en equipo de estudiantes universitarios, demostrado a través del compromiso con el equipo, la satisfacción con los miembros del equipo y el desempeño en la tarea. La investigación siguió una metodología experimental, en la que a través de instrucciones diferenciadas para la tarea, proporcionada a estudiantes universitarios, se indujo tres orientaciones de meta diferentes, una a cada grupo: hacia el aprendizaje, hacia la aproximación al rendimiento y hacia la evitación al rendimiento. Un cuarto grupo fue el de control, dado que no recibió ninguna inducción en las instrucciones de la tarea. Se esperaba que el grupo que recibiera la tarea con instrucciones orientadas al aprendizaje fuera a lograr los mejores resultados en el desempeño, compromiso y satisfacción con el equipo; en comparación con el grupo de control y el que realice la tarea orientada a la evitación al rendimiento, sosteniendo que éste último obtendría los peores resultados de trabajo en equipo. Los hallazgos del estudio indicaron que los miembros del grupo que recibió instrucciones de la tarea orientadas hacia el aprendizaje lograron mayor puntuación en la escala de compromiso con el equipo y un alto nivel de satisfacción con los miembros de su equipo, en comparación con los otros tres grupos. Por su parte, los integrantes del grupo que realizó la tarea orientada a la evitación al rendimiento obtuvieron las puntuaciones más bajas en la satisfacción con los miembros de su equipo, el compromiso con el equipo y el desempeño en la tarea. Además, los miembros del grupo que ejecutó una tarea orientada hacia la aproximación al rendimiento tuvieron el mejor resultado en el desempeño en la tarea. Las implicancias de estos resultados para la teoría y futura investigación sobre el trabajo en equipo son discutidas en esta investigación. / The study examined the influence of induced task’s goal orientation in the outputs of teamwork of college students, assessed through team commitment scale, team membership satisfaction scale and task’s achievement. The research consisted in an experiment, in which goal orientations were induced through differentiated task instructions to each of three groups: one with learning approach orientation, the second group received performance orientation instructions and the third one performance avoidance instructions. A forth group was the control group that did not receive any goal orientation in the instructions. It was expected that the group with the learning orientation task induction would have the best results in each of the teamwork outputs, in comparison to the control group and the avoidance orientation induction group. It was predicted that team with avoidance orientation task instructions would have the worst outcomes. Results showed that the members of the learning orientation task group showed better team commitment scores and higher levels of satisfaction with their team members, compared to the other three groups. On the other side, members of the avoidance performance orientation task instructions group showed lower general outcomes: lower satisfaction with team members and lower team commitment scores, as well as, poorer task achievement. In addition, members of the approach performance orientation group showed better task achievement. Theoretical and future research implications of these results are discussed in this study. / Tesis

The project based on behavioural tests of 7 week old German Shepherd puppies performed in police kennel in Prackovice nad Labem and Domažlice. The project focused on verification of the usability and improvement of the selection of puppies using behavioural test. We tested the possibility of environmental effect (presence of shooting range near the kennel Domažlice) on the later success of puppies in the behavioural test. The aim of the project was collecting additional data which were use to improve and verify procedure for early selection of puppies. We checked the possibility of habituation breeding females and their puppies to noise, including monitoring of the different environments in the kennels in. It was found that different results are affected by of their mothers. This means that puppies raised by mothers from the police kennel near shooting range are better evaluated later in the disciplines of evaluating response to noise compared with pups from mothers of police kennel without shooting range. Worse response to noise had pups from litters with a higher number of pups. Reviews summarizing the literature on heritability of behavioural traits in dogs have been published repeatedly over the last four decades. The conclusions of these reviews vary to some extent. We applied meta-analysis and re-evaluated the literature available collecting 47 references dealing with heritability of behavioural traits in domestic dogs. For each study included, data was extracted for individual behavioural traits. Each of these traits was entered into the analysis as a separate unit of measure, giving a total of 1761 measures. We classified the traits measured in each study into five functional categories (Environment, Herding, Hunting, Play, and Psychical characteristic). The metaanalysis has shown low general heritability of the categorised behavioural traits analysed. Thus, the commonly used behaviour tests for many breeds, to determine the dog's eligibility for reproducing, traditionally required by many associations, is not supported by the present results of the meta-analysis.

Aplicação de meta-heurísticas no escalonamento de motoristas para o transporte de madeira. 2012. Dissertação (Mestrado em Ciências Florestais) Universidade Federal do Espírito Santo, Alegre-ES. Orientador: Prof. Dr. Nilton Cesar Fiedler. Coorientador: Prof. Dr. Geraldo Regis Mauri. O transporte de cargas do setor florestal brasileiro é realizado em sua maior parte pelo modal rodoviário. Sua complexidade exibe a importância de diagnosticar o desenvolvimento da atividade para que se possa, por meio da pesquisa operacional, empregar de forma mais eficiente seus recursos disponíveis sem que haja perda de produtividade. Atualmente, o problema de escalonamento de motoristas é considerado um dos principais entraves à otimização em empresas de transporte, pois apresenta uma grande quantidade de restrições físicas e técnicas. Esta pesquisa teve como objetivo solucionar um problema real de escalonamento de motoristas no transporte de madeira de uma empresa florestal por meio de cinco meta-heurísticas (Algoritmo Genético AG, Algoritmo Memético AM, Clustering Search CS, Greedy Randomized Adaptive Search GRASP e Simulated Annealing SA), comparar os métodos entre si e entre a situação corrente na empresa, e propor uma nova escala de serviços. Para validação da abordagem proposta, foi utilizada uma entrada de dados gerada a partir da pesquisa qualitativa e de estudos de tempos e movimentos. Os resultados indicam que todos os métodos foram eficientes para resolver o problema sobressaindo-se o CS como melhor, seguido do SA, GRASP, AM e AG. O CS conseguiu atender aos objetivos com uma redução em 1/3 do quadro de 150 motoristas além de eliminar médias diárias de horas extras e excedentes que eram de 01h03min e 00h51min, respectivamente. Palavras-chave: transporte florestal, meta-heurísticas, escalonamento de motoristas, logística de transporte, produção florestal.
