Design guidelines and characteristics of beam-shaping microstructure optical fibers

Microstructure optical fibers with flat-top fundamental mode are first proposed by introducing a low-index inner core into the core of index-guiding microstructure optical fibers. The design guidelines and characteristics of beam-shaping microstructure optical fibers are demonstrated. The interrelationships of inner-core index with laser wavelength, air hole diameter and size of inner core are investigated. The influence of the relative size of inner core on the spatial profile of the fundamental mode is demonstrated. Moreover, sensitivity of the flat-top fundamental mode profile from the slight change of the optimum inner-core index value is studied. Starting from these results we deduce that it is possible to fabricate beam-shaping microstructure fibers with nowadays technique. (C) 2005 Elsevier B.V. All rights reserved.

Design guidelines and characteristics for a kind of four-layer large flattened mode fibers

A theoretical method to analyze a kind of four-layer large flattened mode (LFM) fibers is presented. The properties of the fiber, including the fundamental and higher-order modal fields, effective area and bending loss are discussed by comparison. At the same time, the reasons for the different characteristics are considered. The obtained results indicate that the effective area of the four-layer LFM fiber is about 1.3 times larger than that of the conventional standard step-index fiber and the fiber can suppress the higher-order modes via bending effectively. The four-layer LFM fiber has less efficient bend-induced filtering ability than the conventional step-index fiber; however, it has more efficient filtering ability than the three-layer LFM fiber.

A Delphi Process to Optimize Quality and Performance of Drug Evaluation in Neonates

Background: Neonatal trials remain difficult to conduct for several reasons: in particular the need for study sites to have an existing infrastructure in place, with trained investigators and validated quality procedures to ensure good clinical, laboratory practices and a respect for high ethical standards. The objective of this work was to identify the major criteria considered necessary for selecting neonatal intensive care units that are able to perform drug evaluations competently. Methodology and Main Findings: This Delphi process was conducted with an international multidisciplinary panel of 25 experts from 13 countries, selected to be part of two committees (a scientific committee and an expert committee), in order to validate criteria required to perform drug evaluation in neonates. Eighty six items were initially selected and classified under 7 headings: "NICUs description - Level of care'' (21), "Ability to perform drug trials: NICU organization and processes (15), "Research Experience'' (12), "Scientific competencies and area of expertise'' (8), "Quality Management'' (16), "Training and educational capacity'' (8) and "Public involvement'' (6). Sixty-one items were retained and headings were rearranged after the first round, 34 were selected after the second round. A third round was required to validate 13 additional items. The final set includes 47 items divided under 5 headings. Conclusion: A set of 47 relevant criteria will help to NICUs that want to implement, conduct or participate in drug trials within a neonatal network identify important issues to be aware of. Summary Points: 1) Neonatal trials remain difficult to conduct for several reasons: in particular the need for study sites to have an existing infrastructure in place, with trained investigators and validated quality procedures to ensure good clinical, laboratory practices and a respect for high ethical standards. 2) The present Delphi study was conducted with an international multidisciplinary panel of 25 experts from 13 countries and aims to identify the major criteria considered necessary for selecting neonatal intensive care units (NICUs) that are able to perform drug evaluations competently. 3) Of the 86 items initially selected and classified under 7 headings - "NICUs description - Level of care'' (21), "Ability to perform drug trials: NICU organization and processes (15), "Research Experience'' (12), "Scientific competencies and area of expertise'' (8), "Quality Management'' (16), "Training and educational capacity'' (8) and "Public involvement'' (6) - 47 items were selected following a three rounds Delphi process. 4) The present consensus will help NICUs to implement, conduct or participate in drug trials within a neonatal network.

Guidelines for the scoping and environmental assessment of water resources projects. The environment and water resources projects - Volume 1

The following brief is to ensure standard criteria and format are used for the scoping and environmental assessment of water resources projects leading to the production of an environmental report or Environmental Statement. This volume is one of a series giving guidance on water resources projects. The water resources projects will predominantly comprise drought orders and permits, time limited and permanent licences. Smaller projects, such as spray irrigation licences, will not require an environmental assessment. This document forms the basis for discussions between the Environment Agency North East Region, consultees and the applicant. The process aims to produce a thorough assessment. Each section addresses consecutive elements of the assessment process. Section 2 outlines the structure for a scoping document, section 3 outlines the structure for an Environmental Statement and section 4 gives guidance on the role of an Environmental Action Plan. Appendices 1 and 2 should be used in conjunction with the scoping process and cover a wide range of aspects. However, some projects may not require all of them to be included, whilst for others, the inclusion of additional factors may be appropriate.

Guidelines for the scoping and environmental assessment of water resources projects. The environment and water resources projects - Volume 2

In its role as protector of the water environment, the Environment Agency requires significant water resources abstraction applications and schemes such as drought orders, drought permits, time limited licences, and river transfers to be environmentally assessed leading to the production of an environmental report or statement. This may not take the form of a formal Environmental Assessment, but is required to provide environmental information to support applications. (See Volume 1 - Guidance for Scoping and Environmental Assessment for Water Resources Projects in North East Region). This second volume concentrates on the environmental monitoring component of environmental assessments.

Subjetividade e gestão: a dinâmica entre o legal e o legítimo no processo de avaliação de indicadores do INCA

Esta pesquisa buscou compreender a dinâmica entre o legal e o legítimo a partir de um processo de avaliação de indicadores do INCA. Os objetivos foram relatar a opinião dos profissionais sobre a avaliação de desempenho institucional, descrever a percepção de pertencimento e corresponsabilidade dos profissionais nas contratualizações institucionais e apontar obstáculos ao fortalecimento da cultura de avaliação. O objeto do estudo foi construído a partir do referencial teórico da Psicossociologia Francesa. Como trajetória metodológica, para o alcance dos objetivos propostos, foi realizado um estudo de natureza qualitativa, empregando entrevistas semiestruturadas. As entrevistas foram organizadas com auxílio de anotações realizadas pela autora em 62 reuniões cujo tema era avaliação e monitoramento de indicadores. As entrevistas constituíram-se como o material empírico para proceder às análises, visando, sobretudo, a interpretação dos entrevistados sobre demandas estratégicas da gestão. Ao analisar a dinâmica entre o legal e legítimo, concluímos que organização do instituto por normativos dispositivos legais não garante legitimidade das ações propostas. Aspectos (inter) subjetivos contemplados na elaboração de normas diretrizes dificultam capilaridade necessária da informação. Por fim, estudo defende ampliação abordagem valor subjetividade nos processos gestão INCA.

NMFS / Interagency Working Group Evaluation of CITES Criteria and Guidelines.

EXECUTIVE SUMMARY: At present, the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) criteria used to assess whether a population qualifies for inclusion in the CITES Appendices relate to (A) size of the population, (B) area of distribution of the population, and (C) declines in the size of the population. Numeric guidelines are provided as indicators of a small population (less than 5,000 individuals), a small subpopulation (less than 500 individuals), a restricted area of distribution for a population (less than 10,000 km2), a restricted area of distribution for a subpopula-tion (less than 500 km2), a high rate of decline (a decrease of 50% or more in total within 5 years or two generations whichever is longer or, for a small wild population, a decline of 20% or more in total within ten years or three generations whichever is longer), large fluctuations (population size or area of distribution varies widely, rapidly and frequently, with a variation greater than one order of magnitude), and a short-term fluctuation (one of two years or less). The Working Group discussed several broad issues of relevance to the CITES criteria and guidelines. These included the importance of the historical extent of decline versus the recent rate of decline; the utility and validity of incorporating relative population productivity into decline criteria; the utility of absolute numbers for defining small populations or small areas; the appropriateness of generation times as time frames for examining declines; the importance of the magnitude and frequency of fluctuations as factors affecting risk of extinction; and the overall utility of numeric thresh-olds or guidelines.

Transtorno do estresse pós-traumático em policiais militares do Rio de Janeiro

Este trabalho pretende apontar o acometimento do transtorno do estresse pós-traumático em policiais militares do Estado do Rio de Janeiro. Para isso, a autora utiliza sua experiência como psicóloga da PMERJ há 11 anos e descreve inúmeras situações sobre o cotidiano na referida corporação, os desafios de pesquisar a instituição onde trabalha, descreve como funciona o serviço de psicologia e como, a partir do lugar de psicóloga militar, enxerga o homem policial militar, sua identidade e a instituição Polícia Militar. É contextualizado o cenário de violência e criminalidade encontrado pelos policiais de nosso Estado nos últimos anos e são abordados aspectos da formação desses profissionais de segurança pública, que incluem a construção da negação do medo no exercício da atividade laboral e a aderência a um padrão de homem destemido e forte em todos os momentos. Há a tentativa de demonstrar como essas construções contribuem para o adoecimento psíquico desses trabalhadores, por impedi-los de se dar conta de suas fragilidades e limitações, estando sempre em busca de alcançar o padrão do super-homem valorizado como ideal. Discute-se o adoecimento mental entre policiais, especialmente o transtorno do estresse pós-traumático como um problema de saúde pública para além dos muros da PMERJ. São apresentadas as diretrizes atuais em nosso país no tocante a esta temática e por fim são descritas duas estórias detalhadas de policiais militares para ilustrar como a profissão pode atravessar a vida desses trabalhadores, de forma a modificá-las profundamente.

Drawn to the Sea: Charles Bradford Hudson (1865-1939), Artist, Author, Army Officer, with Special Notice of His Work for the United States Fish Commission and Bureau of Fisheries

The biography of Charles Bradford Hudson that follows this preface had its seeds about 1965 when I (VGS) was casually examining the extensive files of original illustrations of fishes stored in the Division of Fishes, National Museum of Natural History, Smithsonian Institution. I happened upon the unpublished illustration of a rainbow trout by Hudson and was greatly impressed with its quality. The thought occurred to me then that the artist must have gone on to do more than just illustrate fishes. During the next 20 years I occasionally pawed through those files, which contained the work of numerous artists, who had worked from 1838 to the present. In 1985, I happened to discuss the files with my supervisor, who urged me to produce a museum exhibit of original fish illustrations. This I did, selecting 200 of the illustrations representing 21 artists, including, of course, Hudson. As part of the text for the exhibit, Drawn from the Sea, Art in the Service of Ichthyology, I prepared short biographies of each of the artists. The exhibit, with an available poster, was shown in the Museum for six months, and a reduced version was exhibited in U.S. and Canadian museums during the next 3 years.

Biographic Memoir of Ernest Ingersoll: Naturalist, Shellfish Scientist, and Author

The name Ernest Ingersoll is well-known to many shellfishery biologists as the author of two outstanding monographs on the shellfisheries of the United States and Canada in the 1880's. The first (Ingersoll, 1881a), entitled "A Report on the Oyster-Industry of the United States," was a 252-page description of historical and contemporary oyster fishing' marketing methods, and statistical data in the eastern provinces of Canada and the coastal states of the United States. The second (Ingersoll, 1887), entitled "The Oyster, Scallop, Clam, Mussel, and Abalone Industries," was a l20-page summary of the first monograph about oysters as well as a history and description of contemporary methods and statistical data of the other shellfisheries. Although Ingersoll was, by profession, a naturalist and author but only briefly a shellfish scientist, these monographs are regarded as benchmarks, providing the principal descriptions of shellfisheries in North America in the 1700's and 1800's.

Workshop and Symposium on Sustainable Small-scale Fisheries: Towards FAO Guidelines on Marine and Inland Small-scale Fisheries, 19-21 September, 2011, Kolkata, West Bengal, India

The workshop and symposium titled Sustainable Small-scale Fisheries: Towards FAO Guidelines on Marine and Inland Small-scale Fisheries was jointly organized by the National Fishworkers’ Forum (NFF) and the Society for Direct Initiative for Social and Health Action (DISHA), in collaboration with the International Collective in Support of Fishworkers (ICSF). The workshop was the first in a series of consultations around the world organized to discuss the Voluntary Guidelines on Small-scale Fisheries (VGSSF) and propose measures, keeping in mind the interests and concerns of small-scale fisheries and fishing communities. The workshop was also a forum to make the role of small-scale fisheries and fishworkers more visible in the context of food security, poverty alleviation and sustainable use of fishery resources. The workshop had 62 participants from both the marine and inland sectors, representing 10 States of India. The participants included fishworkers, representatives of fishworker organizations, policymakers and representatives of multilateral organizations. The workshop was structured to facilitate active interaction and discussion among participants, taking into account linguistic diversity and the contextual differences of the marine and inland sectors. This publication will be useful for fishworkers, fishworker organizations, researchers, policymakers, fish farmers, members of civil society and anyone interested in small-scale fisheries and livelihoods.
