A gestão por competências destacou-se no cenário das organizações públicas brasileiras através do Decreto nº 5.707/2006 como instrumento da política de desenvolvimento dos servidores da administração pública direta, autárquica e fundacional enfatizando a capacitação orientada para o desenvolvimento do conjunto de conhecimentos, habilidades e atitudes necessárias ao desempenho das funções dos servidores, visando ao alcance dos objetivos da instituição. Ocorre que desde 2001, conforme relato da Escola Nacional de Administração Pública - ENAP, dezesseis organizações públicas já praticavam preceitos da gestão por competências, e utilizavam além da capacitação outros processos relacionados a área de gestão de pessoas previstos na teoria sobre gestão por competências. Utilizando a Teoria do Desenvolvimento Organizacional, com método comparativo, estratégia estudo de caso múltiplo e análise documental do período de dez anos, de três organizações, CEF,e TCU, pertencentes ao grupo do relato ENAP, foram constatadas as hipóteses de que cada organização escolheu o procedimento mais adequado a sua estrutura e cultura organizacional para implantar a gestão por competências e que esta teve o processo de implantação em consonância com as respectivas áreas de planejamento e ainda, para implementar mudanças utilizando a gestão por competências não é necessário finalizar o mapeamento de competências individuais de todos os servidores das organizações. As mudanças podem iniciar, após a definição da missão, valores, objetivos estratégicos, visão de futuro (mapeamento de competências organizacionais). Concluindo que inexiste um modelo universal para implantação da gestão por competências, pois, cada organização é influenciada de forma diferente pela política, clima e cultura organizacional.

O objetivo deste trabalho foi estimar parâmetros genéticos para características produtivas, tais como: produção de leite (PL), produção de gordura (PG), duração da lactação (DL) e produção de leite por dia de intervalo de parto (PLDIDP) em búfalos (Bubalus bubalis) na Amazônia Oriental. O trabalho foi realizado na fazenda “Dr. Felisberto Camargo” de propriedade da EMBRAPA/CPATU, onde foram analisados registros produtivos colhidos no período compreendido entre 1967 a 2005. Foram analisados um total de 1.182 registros de fêmeas bubalinas da raça Murrah e seus mestiços. As médias observadas e os desvios-padrãopara PL, PG, DL e PLDIDP foram 1.663,84 ±343,60, 116,84 ±29,71, 269,89 ±56,36 e 3,88 ±1,15 respectivamente. Os parâmetros genéticos foram estimados por meio do método de Máxima Verossimilhança Restrita processada por meio de análises de bicaracterísticas, sendo as características como a produção de leite e gordura consideradas como efeitos fixos a época de parto, grupo genético e ordem de parto do animal, além da cováriavel duração da lactação. As estimativas de herdabilidade (h²) encontrada para as características PL, PG, DL e PLDIDP foram 0,25, 0,18, 0,08 e 0,09 respectivamente, com repetibilidade (r) para PL, PG e DL de 0,33, 0,29 e 0,10 respectivamente. As correlações genéticas entre as características foram 0,93(PL-PG), 0,76 (PL-DL), 0,99 (PL-PLDIDP), 0,89 (PG-DL), 0,87 (PG-PLDIDP) e -0,27 (DLPLDIDP). No rebanho estudado existe expressiva percentagem de animais que foram superiores geneticamente em relação à média da população para as características. Existe considerável variabilidade genética aditiva para as características estudadas, sendo que esta variabilidade pode ser utilizada para promover o melhoramento genético do rebanho.

En este estudio, englobado dentro del campo de la investigación operacional en aeropuertos, se considera el problema de la optimización de la secuencia de descontaminación de nieve de los tramos que componen el área de maniobras de un aeropuerto, denominado RM-AM. Este problema se enfrenta a la optimización de recursos limitados para retirar la nieve de las calles de rodadura y pistas, dejándolas en un estado aceptable para la operación de aeronaves. El campo de vuelos se divide en subconjuntos de tramos significativos para la operación y se establecen tiempos objetivo de apertura al tráfico de aeronaves. Se desarrollan varios algoritmos matemáticos en los que se proponen distintas funciones objetivo, como son la hora de finalización del proceso, la suma de las horas de finalización de cada tramo, o el retraso entre la hora estimada y la hora de finalización. Durante este proceso, se van introduciendo restricciones operativas relativas al cumplimiento de objetivos operativos parciales aplicados a las zonas de especial interés, o relativas a la operación de los equipos de descontaminación. El problema se resuelve mediante optimización basada en programación lineal. Los resultados de las pruebas computacionales se hacen sobre cinco modelos de área de maniobras en los que va creciendo la complejidad y el tamaño. Se comparan las prestaciones de los distintos algoritmos. Una vez definido el modelo matemático para la optiamización, se propone una metodología estructurada para abordar dicho problema para cualquier área de manobras. Se define una estrategia en la operación. Se acomete el área de maniobras por zonas, con la condición de que los subconjuntos de tramos significativos queden englobados dentro de una sola de estas zonas. El problema se resuelve mediante un proceso iterativo de optimización aplicado sucesivamente a las zonas que componen el área de maniobras durante cada iteración. Se analiza la repercusión de los resultados en los procesos DMAN, AMAN y TP, para la integración de los resultados en el cálculo de TSAT y EBIT. El método se particulariza para el caso del área de maniobras del Aeropuerto Adolfo Suárez Madrid Barajas. ABSTRACT This study, which lies within the field of operations research in airports, considers the optimisation of the sequence for clearing snow from stretches of the manoeuvring area of an airport, known as RM-AM. This issue involves the optimisation of limited resources to remove snow from taxiways and runways thereby leaving them in an acceptable condition for operating aircraft. The airfield is divided into subsets of significant stretches for the purpose of operations and target times are established during which these are open to aircraft traffic. The study contains several mathematical models each with different functions, such as the end time of the process, the sum of the end times of each stretch, and gap between the estimated and the real end times. During this process, we introduce different operating restrictions on partial fulfilment of the operational targets as applied to zones of special interest, or relating to the operation of the snow-clearing machines. The problem is solved by optimisation based on linear programming. Computational tests are carried out on five distinct models of the manoeuvring area, which cover increasingly complex situations and larger areas. The different algorithms are then compared to one other. Having defined the mathematical model for the optimisation, we then set out a structured methodology to deal with any type of manoeuvring area. In other words, we define an operational strategy. The airfield is divided into subsets of significant stretches for the purpose of operations and target times are set at which these are to be open to aircraft traffic. The manoeuvring area is also divided into zones, with the condition that the subsets of significant stretches lie within just one of these zones. The problem is solved by an iterative optimisation process based on linear programming applied successively to the zones that make up the manoeuvring area during each iteration. The impact of the results on DMAN, AMAN and TP processes is analysed for their integration into the calculation of TSAT and EBIT. The method is particularized for the case of the manoeuvring area of Adolfo Suarez Madrid - Barajas Airport.

The Brazilian agricultural research agency has, over the years, contributed to solve social problems and to promote new knowledge, incorporating new advances and seeking technological independence of the country, through the transfer of knowledge and technology generated. However, the process of transfering of knowledge and technology has represented a big challenge for public institutions. The Embrapa is the largest and main brazilian agricultural research company, with a staff of 9.790 employees, being 2.440 researchers and an annual budget of R$ 2.52 billion. Operates through 46 decentralized research units, and coordinate of the National Agricultural Research System - SNPA. Considering that technology transfer is the consecration of effort and resources spent for the generation of knowledge and the validity of the research, this work aims to conduct an assessment of the performance of Embrapa Swine and Poultry along the production chain of broilers and propose a technology transfer model for this chain, which can be used by the Public Institutions Research – IPPs. This study is justified by the importance of agricultural research for the country, and the importance of the institution addressed. The methodology used was the case study with a qualitative approach, documentary and bibliographic research and interviews with use of semi-structured questionnaires. The survey was conducted in three stages. In the first stage, there was a diagnosis of the Technology Transfer Process (TT), the contribution of the Embrapa Swine and poultry for the supply chain for broiler. At this stage it was used bibliographical and documentary research and semi- structured interviews with agroindustrial broiler agents, researchers at Embrapa Swine and Poultry, professionals of technology transfer, from the Embrapa and Embrapa Swine and Poultry, managers of technology transfer and researchers from the Agricultural Research Service - ARS. In the second step, a model was developed for the technology transferring poultry process of Embrapa. In this phase, there were made documentary and bibliographic research and analysis of information obtained in the interviews. The third phase was to validate the proposed model in the various sectors of the broilers productive chain. The data show that, although the Embrapa Swine and Poultry develops technologies for broiler production chain, the rate of adoption of these technologies by the chain is very low. It was also diagnosed that there is a gap between the institution and the various links of the chain. It was proposed an observatory mechanism to approximate Embrapa Swine and Poultry and the agents of the broiler chain for identifying and discussing research priorities. The proposed model seeks to improve the interaction between the institution and the chain, in order to identify the chain real research demands and the search and the joint development of solutions for these demands. The proposed TT model was approved by a large majority (96.77%) of the interviewed agents who work in the various links in the chain, as well as by representatives (92%) of the entities linked to this chain. The acceptance of the proposed model demonstrates the willingness of the chain to approach Embrapa Swine and Poultry, and to seek joint solutions to existing problems.

The starting point of the present work consisted of investigating the development of biotechnology in the Northeast region of Brazil from the perspective of a Regional Innovation System (RIS). The theoretical framework adopted relied on the approaches and concepts presented by the Neo-Schumpeterian perspective. This framework was chosen because, by means of the Innovation System concept, this literature allows us to analyze the relationships and configurations of actors, as well as the role of the state and of social, science and technology, and economic policies in the studied region. The analysis considered four selected dimensions: physical infrastructure, human capital, scientific production, and funding. These variables were chosen because they allow us to verify the possibilities and limitations of developing a biotechnology RIS in the Northeast of Brazil, and these elements would help in answering the question behind this dissertation. The location of the physical infrastructure was determined by means of bibliographic and documental research and interviews with heads of institutions that do biotechnology research. Regarding human capital, the analysis focused on resource training in biotechnology, highlighting graduate courses and research groups in the area. To measure knowledge production, we delimited scientific collaboration among researchers in the field of biotechnology as the focus of this category. For the funding dimension, information was gathered from reports available at the websites of national and state funding agencies. The data was analyzed through method triangulation, involving quantitative and qualitative research stages. To back the analyses, we revisited the integration policies in the area of Science, Technology and Innovation. Our analysis has shown that these policies play a crucial role in the development of biotechnology in the region being studied. The data revealed that the physical infrastructure is concentrated in only three states (Bahia, Ceará, and Pernambuco). In this regard, the Northeast Biotechnology Network (Renorbio) stands out as a strategic actor, enabling states with poor infrastructure to develop research through partnerships with institutions located in another state. We have also verified that the practices involving human resource training and knowledge production are factors that enable the emergence of a regional system for biotechnology in the studied region. As limitations, we have verified the low immersion level of regional actors, the heterogeneity of socioeconomic indicators, the lack of financial resources, and a low innovation culture in the business sector. Overall, we have concluded that the development of a Regional Innovation System in Biotechnology, based on the current regional dynamics, depends on an effective change in the behavior of the social agents involved, both in the national and regional dimensions as well as in the public and private spheres
