Analisa em que grau os elementos, métodos e artefatos preconizados pela arquitetura corporativa podem ser adequados ao processo de gestão estratégica na Câmara dos Deputados da República Federativa do Brasil. Essa adequabilidade se dá na medida em que houver o aproveitamento de esforço desprendido na implantação da gestão estratégica, em termos de criação de cultura organizacional, de aproveitamento de metodologias e artefatos já utilizados, e simultaneamente permitir sua evolução ao responder questões não atendidas pelo atual modelo. São descritos os principais conceitos relacionados à arquitetura corporativa e os modelos de referência Zachman e TOGAF 9.1, incluindo o processo de desenvolvimento da arquitetura - ADM (Architecture Development Method), bem como o Metamodelo de Conteúdos. Também são apresentados conceitos relacionados ao planejamento estratégico e formulação da estratégia, o Balanced Scorecard - BSC e o processo de Gestão Estratégica construído e utilizado na Câmara dos Deputados. Para se relacionar os elementos da Gestão Estratégica da Câmara dos Deputados com os elementos preconizados pelo modelo TOGAF 9.1, construiu-se uma tabela com a relação entre as entidades previstas no modelo TOGAF 9.1 e práticas da Gestão Estratégica da Câmara dos Deputados. Para avaliar o grau de contribuição da arquitetura corporativa para enfrentar questões ainda não resolvidas na gestão estratégica daquela instituição, elaborou-se um quadro contendo a relação entre as questões estratégicas e artefatos do modelo TOGAF 9.1 que endereçam essas questões. Para facilitar o entendimento das entidades do Metamodelo de Conteúdos, elaborou-se um glossário com os termos utilizados neste componente do TOGAF 9.1. Concluiu-se pela adequação da arquitetura corporativa ao processo de gestão estratégica da Câmara dos Deputados, de acordo com os critérios definidos previamente.

Plano de implantação de uma arquitetura orientada a serviços - SOA - na Câmara dos Deputados

Apresenta um plano para implantação de uma Arquitetura Orientada a Serviços "SOA", na Câmara dos Deputados - Brasil. O plano de implantação SOA foi estruturado em dois projetos: "Entender SOA" e "Implantar SOA", descritos em suas macro atividades e foi embasado em um arcabouço teórico fundamentado em significativa literatura pesquisada que incluiu os modelos de referência e de arquitetura SOA disponíveis. Foram abordados, além dos aspectos tecnológicos, as questões de governança de TI e questões de cultura organizacional que precisam ser consideradas em projetos dessa natureza, considerando que SOA não é simplesmente uma questão de tecnologia, mas fundamentalmente uma questão de negócio e governança empresarial. Os aspectos de TI também foram explorados de forma suficiente para que as equipes técnicas tenham condições de implementar os princípios de desenho da arquitetura SOA.

Reference Points Based on Dynamic Optimisation: A Versatil Algorithm for Mixed Fishery Management with Bio-economic Agestructured Models

Single-species management objectives may not be consistent within mixed fisheries. They may lead species to unsafe situations, promote discarding of over-quota and/or misreporting of catches. We provide an algorithm for characterising bio-economic reference points for a mixed fishery as the steady-state solution of a dynamic optimal management problem. The optimisation problem takes into account: i) that species are fishing simultaneously in unselective fishing operations and ii)intertemporal discounting and fleet costs to relate reference points to discounted economic profits along optimal trajectories. We illustrate how the algorithm can be implemented by applying it to the European Northern Stock of Hake (Merluccius merluccius), where fleets also capture Northern megrim (Lepidorhombus whiffiagonis) and Northern anglerfish (Lophius piscatorius and Lophius budegassa). We find that optimal mixed management leads to a target reference point that is quite similar to the 2/3 of the Fmsy single-species (hake) target. Mixed management is superior to singlespecies management because it leads the fishery to higher discounted profits with higher long-term SSB for all species. We calculate that the losses due to the use of the Fmsy single-species (hake) target in this mixed fishery account for 11.4% of total discounted profits.

Stock assessment of protogynous fish: evaluating measures of spawning biomass used to estimate biological reference points

In stock assessments, recruitment is typically modeled as a function of females only. For protogynous stocks, however, disproportionate fishing on males increases the possibility of reduced fertilization rates. To incorporate the importance of males in protogynous stocks, assessment models have been used to predict recruitment not just from female spawning biomass (Sf), but also from that of males (Sm) or both sexes (Sb). We conducted a simulation study to evaluate the ability of these three measures to estimate biological reference points used in fishery management. Of the three, Sf provides best estimates if the potential for decreased fertilization is weak, whereas Sm is best only if the potential is very strong. In general, Sb estimates the true reference points most closely, which indicates that if the potential for decreased fertilization is moderate or unknown, Sb should be used in assessments of protogynous stocks. Moreover, for a broad range of scenarios, relative errors from Sf and Sb occur in opposite directions, indicating that estimates from these measures could be used to bound uncertainty.

A study of the Eastern Pacific fishery for tuna baitfishes, with particular reference to the anchoveta (Cetengraulis mysticetus)

ENGLISH: Most of the catches of yellowfin and skipjack tuna from the Eastern Pacific Ocean are made by vessels fishing with poles and lines and live bait. From 1931 to 1954, these baitboats, on the average, accounted for over three-fourths of the total annual California landings of yellowfin and skipjack (Shimada and Schaefer, 1956). With the substantial increase in recent years in the production of the tropical tunas, there have been greater demands for live bait. This increased need for larger amounts of baitfishes has given rise to important questions relating to the manner in which these populations may be most wisely used. The Inter-American Tropical Tuna Commission has been concerned with various aspects of this problem since its establishment in 1950. This report presents some of the results obtained from the Commission's studies of the baitfishes important to the fishery for yellowfin and skipjack tuna. It traces briefly the origin and development of the bait fishery, describes its operations, extent, and yield, and discusses some aspects of the effects of exploitation upon the Eastern Pacific baitfish populations, particularly of the anchoveta (Cetengaulis mysticetus). SPANISH: Los barcos que emplean cañas y cuerdas y carnada viva, son los que realizan la mayor parte de la pesca de atún aleta amarilla y barrilete en el Océano Pacifíco Oriental. De 1931 a 1954 estos barcos han desembarcado, en promedio, más de las tres cuartas partes de las pescas anuales de ambas especies (Shimada y Schaefer, 1956). Con el aumento sustancial en dicha producción en los últimos años, ha habido una mayor demanda por carnada viva. Esta creciente necesidad de obtener cantidades mayores de pecescebo, ha originado importantes cuestiones relativas a la mejor forma en que estas poblaciones pueden ser utilizadas. A la Comisión Interamericana del Atún Tropical le ha tocado ocuparse de varios aspectos de este problema, desde que fué establecida en el año 1950. Este informe ofrece algunos de los resultados obtenidos a través de los estudios de la Comisión sobre los peces-cebo importantes para la pesquería de atún aleta amarilla y barrilete; señala brevemente el origen y desarrollo de la pesquería de carnada; describe sus operaciones, extensión y rendimiento, y trata algunos aspectos de los efectos de la explotación sobre las poblaciones de dichos peces en el Pacifíco Oriental, particularmente de la anchoveta (Cetengraulis mysticetus).

FTT-MA: A Flexible Time-Triggered Middleware Architecture for Time Sensitive, Resource-Aware AmI Systems

There is an increasing number of Ambient Intelligence (AmI) systems that are time-sensitive and resource-aware. From healthcare to building and even home/office automation, it is now common to find systems combining interactive and sensing multimedia traffic with relatively simple sensors and actuators (door locks, presence detectors, RFIDs, HVAC, information panels, etc.). Many of these are today known as Cyber-Physical Systems (CPS). Quite frequently, these systems must be capable of (1) prioritizing different traffic flows (process data, alarms, non-critical data, etc.), (2) synchronizing actions in several distributed devices and, to certain degree, (3) easing resource management (e.g., detecting faulty nodes, managing battery levels, handling overloads, etc.). This work presents FTT-MA, a high-level middleware architecture aimed at easing the design, deployment and operation of such AmI systems. FTT-MA ensures that both functional and non-functional aspects of the applications are met even during reconfiguration stages. The paper also proposes a methodology, together with a design tool, to create this kind of systems. Finally, a sample case study is presented that illustrates the use of the middleware and the methodology proposed in the paper.
