This work is a case study based on Belém Jewelry Pole, whose main issue is to understand how the social network (which the Pole is inserted) influences on innovation process on this area. The main objective is to analyze how interorganizational networks impacted/impact on the potential for innovation, creating both limits and opportunities for the companies development. The adopted method analyzed the historical jewelry industry trajectory since the beginning of mineral extraction in the city of Itaituba (in the Pará State) until nowadays. Primary and secondary data were used allowing the view of the dynamics of the network during transformation periods of the main involved actors in the process. The prospect of embeddedness structural as analysis technique allowed verifying the quality of interactors ties, as well as the visualization of their structures. During the jewelry industry trajectory was verified a change in the quality of social relations, modifying the information flow, trust and associations of various links in the production chain. Both direct and indirect ties facilitated the access to remote networks entering new information related to new products, processes and market aspects. This interaction has led to raising the innovation potential causing a qualitative and quantitative improvement in competitiveness of organizations. Some embedded ties allowed the formation of partnerships bringing various economic earnings for those involved in the relationship. Thus, it is understood how aspects related to the position, architecture and quality of ties in a wide social network influenced on the innovation process and eventual jewelry industry trajectory

Este trabalho consiste num estudo de caso na empresa Alesat cujo objetivo geral foi compreender o modelo de gestão de pessoas adotad por uma empresa norteriograndense à luz do modelo estratégico de gestão de pessoas. O estudo baseouse na literatura de Albuquerque (2002); Ashton, Haffenden e Lambert (2004); Fischer (2002); Legge (1995); Mascarenhas (2008); Tanure, Evans e Pucik (2007), Ulrich (2000) e Vasconcelos (2006), dentre outros, paa apreender como os profissionais que atuam no delineamento de estratégias e operacionalização das ações de recursos humanos concebem o seu posicionamento e eventual alinhamento à estratégia organizacional. O método analisou e descreveu o modelo de gestão de pessoas da empresa campo do estudo. A coleta de dados contou com a realização de entrevistas semi-estruturadas com os 05 gestores de RH que atuam na matriz (Natal/RN). Também foram coletados dados secundários, além de documentos e comunicações internas da empresa que tocam ao RH. Os dados coletados foram analisados à luz da análise de conteúdo de Bardin (1977). Através da análise, foi possível identificar políticas e práticas de RH que perpassam um modelo de gestão de pessoas bem definido e consolidado, com impactos mensuráveis no desempenho organizacional. Percebeu-se, também, a forte disseminação de uma cultura organizacional com foco no posicionamento estratégico e na informalidade e proximidade das relações, que permeiam o modelo de gestão de pessoas. Concluiuse a coerência entre as políticas estratégicas da empresa e as de recursos humanos. A pesquisa apreendeu as interfaces do modelo de gestão estratégica de pessoas da empresa; estas implicam uma alternância entre pensamentos e atitudes vinculados à versão hard, onde o papel das prática de RH é garantir que as pessoas alcancem os objetivos empresariais; e à versão soft, onde o papel do RH é desenvolver o capital intelectual e humano para diversificar os negócios e alcançar resultados sustentáveis e diferenciados. O salto qualitativo atingido pela Ale pode ser atribuído ao fato de possuir um RH situado hierarquicamente na alta cúpula da empresa, em posição de consultoria interna o que oferece perspectivas de atuação que vão muito além das rotinas operacionais desenvolvidas por boa parte das empresas no Brasil

The kinanthropometric characteristics are used by the sports science as selection criteria and detection of talents. Hence, this study aimed at comparing the anthropometrical profile, the body composition, the somatotype and the vertical jumps of the beach volleyball players. This study consists of 79 male beach volleyball players, being forty nine (n=49) Brazilian participants of the National Circuit and thirty (n=30) of 15 countries participating in the XV Pan American Games. In order to analyze the vertical jumps of the Brazilian the participants were allocated into two groups (G1 and G2) in agreement with the national ranking of their teams. The vertical jump protocol developed by Smith and collaborators was used to evaluate the vertical jumps of spike and block. The Heath-Carter anthropometrical technique (1990) was used for calculating the somatotype. The Student s t test with the Bonferroni adjustment was used to calculate the differences among the investigated variables. The multiple regression analysis was used to identify the contributions of the anthropometrical variables in the performance of the vertical jumps and the multivariance analysis was used to calculate the differences among the components of the somatotype. The Brazilian athletes of G1 were better than G2 in the spike jump (p <0.01), block jump (p <0.01) and in the block difference (p <0.01). The prediction model of the spike jump of G2 included the body mass and standing spike reach (adjusted R2 = 0.77), the body mass and the standing block reach were also included in the model of the block jump (adjusted R2 = 0.73). The regression model of G1 was not statistically significant. As for the somatotype, statistically significant differences were found between the Brazilians and the Pan Americans (Wilks' lambda = 0.498; p <0.05). The Brazilian somatotype was classified as balanced mesomorph (2.7-4.3-3.0) and the Pan American somatotype as endomorphic mesomorph (3.5-4.6-2.4). As to the specific position of the block game (2.8-4.3-2.9) and the defense game (2.6-4.4-3.0), the Brazilian somatotype was classified as balanced mesomorph and the Pan American somatotype, the block (3.7-4.4-2.4) and the defense (3.4-4.9-2.3), was classified as endomorphic mesomorph. In conclusion, the vertical jump height (spike and block) influences the male Brazilian beach volleyball players performance. The physical type of the Brazilian blockers and defenders was similar with relationship to the somatotype. The Brazilian and Pan American beach volleyball players differ in terms of kinanthropometric characteristics. This work had a multidisciplinary feature with the participation of several departments and laboratories, like the Physiotherapy Department, the Nutrition Department, the Physical Education Laboratory, thus corroborating the multidisciplinary research feature

Objective: Identify phenotype and genotype parameters of female volleyball players at different performance levels to help in player selection. Methods: We identified characteristics of phenotype and genotype using the somatotype method (Heath Carter); anthropometry (weight, height and fat percentage); dermatoglyphics (Cummins and Midlo s method) as well as applying physical quality tests (Shuttle Run to assess agility and the Sargent Jump Test adapted for spike and block reach). The sample was composed of 179 players (54 from national teams and 125 from state teams). Results: Somatotype was similar among the performance levels in the mesomorphic component. The Height and ectomorphic component were greater in national team players as was spike and block reach. The vertical jump height for the spike was similar between the national under-17 team and the state teams observed, but in the block jump the lower level players were better. The dermatoglyphics characteristics identified were similar among the groups studied. Conclusions: The results of the variables studied show that somatotype, height, spike reach and block reach are fundamental parameters in player selection and in the specific characteristics of each game position of this sport. This paper proposes a multidisciplinary approach applicable in the fields of physical education, medicine and nutrition

The aim of this research was to analyse genetic markers, anthropometry and basic physical qualities in the differret stages of sexual maturation in swimmers in Paraíba. It is characterised as a descriptive cross sectional study. The sample was composed of 119 swimmers (males) that were divided among the stages of sexual maturation, from 7 to 17,9 years of age. They were associated to a local federation, the Confederação Brasileira de Desportes Aquáticos. The tests used were: genetic markers dermatoglyphics; Anthropometry body mass, stature, arm span, fat percentage and somatotype; physical qualities speed tests (25 meters crawl), strength (vertical jump) to inferior limbs, verarm throwing arremesso of a 2kg medicineball to superior limbs and abdominal), resistence (12 minutes to swimming), agility (he multistage 20-meter shuttle run test), flexibility (sit and reach test ) and coodination (stroke index); power of swimming (mean velocity in 25 meters mutiplied by body mass) and the self assessment of the sexual maturation supervised by a pediatric specialist. In the analyses we used the test normality of Shapiro-Wilk, then, we used ANOVA- one way followed by Post-Hoc test of Scheffé. The data showed in dermatogliphics a genetic tendence to velocity (L>W) with a predominance of the meso-ectomorphic somatotype profile; in relation to the physical qualities there was an evolution of the results in every stage due to the antropometric variables, except in the coordination tests. There were no significative differences between the stages. We conclude that swimming in Paraíba is composed of a signicative number of velocists with a mesomorph somatotype profile and low fat percentage, and that made it posssible to us to recomend that the trainings must be individual and according to personal characteristics of each athlete, and that the used variables must be specific for every region of the country. This dissertation presents a relation of multidiciplinar interface and its content has an application in Physical Education and Medicine

O sedentarismo é cada vez mais acentuado entre os adolescentes em todo o mundo. Objetivou-se neste estudo analisar o estado nutricional e a aptidão física de escolares norte-rio-grandenses. Participaram 2065 sujeitos, selecionados aleatoriamente (Masc = 1066, Fem = 999) (Natal n=1158; Mossoró n= 312; Lajes n= 231), divididos em três grupos etários pelos estágios maturacionais: 10 a 12 anos, 13 a 14 anos e _ 15 anos. Foi avaliada a composição corporal (IMC, dobras cutâneas tríceps e subescapular); o hábito alimentar (questionário de prevalência do consumo por grupo alimentar); o índice de atividade física (questionário Baeck) e o nível de aptidão física (testes do salto em distância, flexibilidade, resistência abdominal e cardiovascular). Utilizando-se a estatística descritiva, testes de médias pela análise dos intervalos de confiança, o teste de Kruskall-Wallis, teste t, o Qui2 e o coeficiente de contingência. Encontraram-se diferenças significativas com p < 0001 na distribuição do índice de massa corporal (n = 1701); Região Leste Potiguar (RLP) com excesso de peso e obesidade de 16,8 % e 15,2 %, a Região Oeste 16,3% e 9,6 % e a Região Central 10,4 % e 3,9 %, com as escolas privadas contribuindo significativamente na prevalência dessas variáveis nas RLP e ROP com p < 0,003 e p < 0,001 respectivamente. O hábito alimentar demonstrou que 98,3% dos sujeitos consomem alimentos do grupo das massas 98,3%; cereais 97,7%; laticínios 94,7%; frutas 92,3%; gorduras 88,3% e as hortaliças 61,6%, não havendo diferenças significativas no consumo alimentar entre o tipo de escolas e gênero (n = 300). No índice de atividade física habitual há diferenças entre esses respectivos extratos: 2,65±0,78 e 2,81±0,80 (p < 0,014) e 2,89±0,82 e 2,57±0,78 (p < 0,001), com as práticas de atividades esportivas, programas de exercícios físicos e lazer ativo mais significativo em escolas privadas 2,85 ± 1,06 e 3,37±1,26 (p < 0,001) em prol do sexo masculino com 3,47±1,24 e 2,75±1,03 (p <0,001). Resistência abdominal ( =19) e força de membros inferiores ( =128,5 cm) foram classificadas como muito fraco , a flexibilidade ( =26,9 cm) razoável e resistência geral ( =1439 m) como bom . Conclui-se que o hábito alimentar e o baixo índice de atividade física habitual influenciam negativamente os índices da aptidão física relacionada à saúde dos escolares, com menor incidência em instituições privadas em função das práticas esportivas. Este estudo apresenta relação de interface multidisciplinar, tendo o seu conteúdo uma aplicação nos campos da Medicina, Nutrição e Educação Física

Background: Several studies emphasize the importance of assessing the knee function after anterior cruciate ligament (ACL) reconstruction. The influence of several variables on the function of these patients has been analyzed, but there is no consensus in the science literature. Purpose: To evaluate the correlation between the torque and balance on the knee function after ACL reconstruction. Methods: 23 males patients with ACL reconstruction were tested. The procedures of the study included analysis of concentric peak torque at 60o/s and 180o/s of quadriceps femoris and hamstring muscle with a isokinetic dynamometer. The balance in single-limb stance was measured with stabilometry. The functional performance were performed by two hop tests. To estimate the subjective function of the patients was applied Lysholm Knee Scoring Scale and a Global Rating scale. Results: The analysis of data showed a moderate positive correlation between knee extensor torque and functional performance tests (r= 0,48; p=0,02). A moderate negative correlation was found between the two variables of the stabilometry center of pressure and average speed of centre of pressure and the Global Rating scale (r = -0.4, p = 0,04 and r = -0,49, p = 0 ,02, respectively). No correlation was found between peak torque and balance in single-limb stance. Conclusion: The results of the present study suggest that knee extensor strength and postural balance have some influence on knee function in patients after ACL reconstruction

The aerial activities, leaps and slaps with parts of the body in the surface of water, are part of the behavioral repertoire of several species of cetaceans. Among them, the spinner dolphin, Stenella longirostris, shows greater diversity in such behavior. For the spinner dolphins of Fernando de Noronha, the aerial activities are classified as vertical and horizontal, with eight patterns to be noted (tail slap, head slap, motor boating, partial leap, leap, spin, tail over head and tail over head with spin) discriminated between these categories. Such behaviors can be used as a parameter to identify behavioral changes, as well as patterns of daily and seasonal activity. In this manner, this study aimed to characterize the frequency in performance of such activity while the dolphins were within the Dolphin Bay of Fernando de Noronha, and verify possible daily and seasonal hourly fluctuations on such behaviors. The data analyzed in this study was acquired during the period of January 2006 through December 2010, totaling 1431 days of observation from land set point, with 113027 aerial activities registered, daily average of 72,27 (SD=96,10). During 5478h and 54 min of observation the horizontal aerial activity was the most observed and rotation was the most executed pattern. Greater frequency of execution of aerial activity was observed in adults, but for both adults and calves, was observed a predominance of horizontal activities, with spin being the pattern most executed. Positive correlation was observed between the amount of aerial activity performed and the number of animals inside the Bay. Hourly daily fluctuation was observed in the expression of aerial activities by spinner dolphins, and was observed a peak of activity between 8h and 8h59min for the overall frequency relative of aerial activities, as well as for the categories and patterns. Seasonal differences were observed between the rainy and dry season with the greater amount of activity being observed during the rainy season. Nevertheless, the same profile of frequency relative of aerial activity was observed in both seasons with the peak amount being during the same period. When discriminated the aerial activities in categories and patterns, for both seasons, there was a similar pattern of hourly fluctuation; for most of parameters, higher frequency relative of execution of aerial activity remain between 8h and 8h59min

La Escuela Secundaria es la etapa final de la Educación Básica y su objetivo es profundizar los conocimientos adquiridos anteriormente, con vistas tanto a la continuidad de los estudios por parte de los alumnos como también a su formación profesional. Considerando el carácter excluyente y elitista de la Escuela Secundaria brasileña, solo recientemente las matrículas de los estudiantes sordos comienzan a ampliarse, y los profesores se deparan con el desafío de lidiar con ese tipo de discente en aulas regulares. Tanto la política de educación especial, desde una perspectiva inclusiva, como la Ley nº 10.436/2002 – reglamentada por el Decreto nº 5.626/2005 – posibilitaron un gran salto para la educación de los sordos en el país. La primera, por la defensa de una escuela atenta a las peculiaridades y demandas de sus discentes; la segunda, por reconocer la Lengua de Señas Brasileña como medio de comunicación y expresión legítimo de la comunidad de sordos y por indicar medidas que garanticen el derecho al acceso y al éxito escolar de la población sorda dentro de la escuela. Amparado en esas discusiones, este estudio tuvo como objetivo analizar el proceso de escolaridad de alumnos sordos de una Escuela Secundaria pública y estatal del municipio de Natal, Rio Grande do Norte. Se realizó un estudio de caso de tipo cualitativo. Los sujetos fueron tres discentes sordos que estaban terminando la Escuela Secundaria, una profesora de Portugués y dos intérpretes de Lengua de Señas Brasileña. Como procedimiento de investigación, se utilizaron entrevistas (grabadas en audio y video), observaciones y análisis de documentos. La participación de los sujetos sordos demandó cuidados éticos adicionales, tales como la traducción del Término de Consentimiento Libre y Aclarado y del guion de la entrevista a la Lengua de Señas Brasileña. Los resultados apuntan que el acceso y la permanencia en la escuela secundaria fueron garantizados, no obstante había poca participación en las clases y el aprendizaje de los contenidos escolares estaba comprometido. Había traductores/intérpretes de Lengua de Señas Brasileña, los cuales, sin embargo, solo iniciaron sus actividades tres meses después del comienzo del periodo lectivo. La profesora y los intérpretes no mantuvieron interacciones que facilitasen el aprendizaje o la participación de los estudiantes, quienes se encontraban siempre juntos y en un lugar determinado del aula, sin mayores interacciones con sus pares normo-oyentes. Los discentes sordos estaban terminando la Escuela Secundaria con edades superiores a 17-18 años, los cuales revelaron no tener perspectivas de continuidad en sus estudios o de inserción en el mercado laboral. Se concluye que la escolaridad de los alumnos sordos en la escuela investigada apunta a la necesidad de una reorganización curricular que atienda a las especificidades lingüísticas y sociales de esos estudiantes.

Introduction: Kinesio Taping (KT) has been used in healthy people to improve neuromuscular performance, however, few studies have evaluated its chronic effects, despite being suggested. Objective: To analyze the chronic effects of KT on neuromuscular performance of the quadriceps, the oscillation of the center of pressure and lower limb function in healthy women. Methods: blinded, randomized, controlled trial, composed of 60 women (mean age 21.9 ± 3.3 years and BMI 22.3 ± 2.2 kg / m2) submitted to the evaluation of oscillation of the center of pressure through the baropodometry, the lower limb function by the hop test, isokinetic knee performance, the electromyographic activity of the vastus lateralis (VL) and joint position sense of the knee (JPS). Then, participants were randomly divided into three groups of twenty: control - did not apply the KT; placebo - application of KT without tension on the quadriceps; Kinesio Taping - application of KT with tension in the same muscle group. The evaluations were conducted in five moments: prior to application of KT, immediately after the application, 24h, 48h after application and 24 hours after its removal (72h). SPSS 20.0 was used for statistical analysis. The KS test was used to verify the data normality, the Levene test for homogeneity of variances and a mixed-model ANOVA 3x5 to check intra and inter-group differences. Results: there was no difference in peak torque, the power, nor the electromyographic activity or SPA (p> 0.05) between groups. The displacement speed of center of pressure reduced immediately after the application on kinesio taping group (p <0.001), but with no differences between the groups (p = 0.28). There was a reduction in the time of peak torque among the three groups in the evaluations after KT application (p <0.001) and an increase in single hop in all groups (p <0.001), but with no differences between them. Conclusion: KT can not change, in a chronic way, the lower limb function, the oscillation of the center of pressure, the isokinetic performance, the JPS of the knee and the electromyographic activity of VL muscle in healthy women.

In control loops valve stiction is a very common problem. Generally, it is one of main causes of poor performance of industrial systems. Its most commonly observed effect is oscillation in the process variables. To circumvent the undesirable effects, friction compensators have been proposed in order to reduce the variability in the output. This work analyzes the friction compensation in pneumatic control valves by using feedback linearization technique. The valve model includes both dead zone and jump. Simulations show that the use of this more complete model results in controllers with superior performance. The method is also compared through simulations with the method known as Constant Reinforcement (CR), widely used in this problem.

Ce travail a recherché sur le processus de préparation corporel\vocal\énergique de l’acteur pour la rue. Notre quête principale c’est comprendre les processus qui l'acteur se déplace afin de développer une énergie à la scène dans la rue. C'est cette énergie qui est mis en place et se rapporte à le passant\spectateur? Qui attire l'attention de passant\spectateur? Serai l'histoire? Le code vestimentaire ou être une expressivité dynamisée? Serai une énergie présente dans le corps de l'acteur qui se relacione avec les passants? Comme l'acteur se rapporte à l'espace urbain? Pour tenter de répondre à ces questions, nous allons utilisé certains principes de la physique moderne, tels comme: la Théorie Quantique et le Principe d'Incertitude, autan la Théorie du Chaos. Le théâtre jouée dans les rues, surtout par le biais de longs prolongements de construction scénique, cependant, lorsque présentée au public, est prise par les autres causalités, car étant situé sur la rue, l'acteur devient assujettie à cet espace et ne peut pas nier la possibilité des faits qui peuvent se produire. Selon la physique quantique l'énergie se propage dans un espace vide, la quantité d'énergie physique étant échangé dans la rue, ce qui entraîne le moment magique où les corps des acteurs, des échanges constants avec les spectateurs, en permettant le saut quantique: le spectacle théâtral de la rue.
