Hydrobiological service for observations and control of surface waters in the USSR

Technological progress, having reached in our time an unprecedented speed, is still increasing the rate of mineral extraction, industrial construction, and the mastering of new kinds of energy is growing. Correspondingly the anthropogenic load on the biosphere is increased and that requires the comprehensive development of monitoring the anthropogenic changes in the natural environment. Among problems resulting from the scientific-technological development, a noticeable place is given to the problem of pure water. Surface land waters proved to be a sensitive link in the natural environment. The hydrobiological service for observations and control of the surface waters is one of the subsystems of the State/Federal Service for Observations and Control of pollution levels in environmental objects, conducted by the USSR State Committee for Hydrometeor- ology and Control of the Natural Environment. This paper summarises the the main principles of the organisation and goals of the national system of monitoring of the state of the natural environment in the USSR.

Radio-aware service-level scheduling to minimize downlink traffic delay through Mobile Edge Computing

One of the most challenging problems in mobile broadband networks is how to assign the available radio resources among the different mobile users. Traditionally, research proposals are either speci c to some type of traffic or deal with computationally intensive algorithms aimed at optimizing the delivery of general purpose traffic. Consequently, commercial networks do not incorporate these mechanisms due to the limited hardware resources at the mobile edge. Emerging 5G architectures introduce cloud computing principles to add flexible computational resources to Radio Access Networks. This paper makes use of the Mobile Edge Computing concepts to introduce a new element, denoted as Mobile Edge Scheduler, aimed at minimizing the mean delay of general traffic flows in the LTE downlink. This element runs close to the eNodeB element and implements a novel flow-aware and channel-aware scheduling policy in order to accommodate the transmissions to the available channel quality of end users.

Creche Odetinha: um estudo de caso

Esta Pesquisa, de natureza qualitativa, teve por objetivo, descrever e analisar o processo de formação (2009) de um grupo de educadores os Agentes Auxiliares de Creche1 (AAC)-, recém concursados, através de um Estudo de Caso. Para tanto, fez parte das análises as recentes mudanças nas políticas de educação infantil do município do Rio de Janeiro (1997-2010) e o percurso de constituição da unidade de educação infantil -Creche Municipal Odetinha Vidal de Oliveira, através do relato de alguns de seus líderes comunitários. No município do Rio de Janeiro, as creches públicas resultaram da transferência das instituições que pertenciam à antiga Secretaria de Desenvolvimento Social (SMDS), atual Secretaria Municipal de Assistência Social (SMAS), para a Secretaria Municipal de Educação (SME). Atualmente, a rede municipal de ensino totaliza 255 creches municipais, com 33.348 alunos, em horário integral (7h -17h). No ano de 2005, o poder executivo do município do Rio de Janeiro, através da Lei 3985 de 08 de abril, criou a categoria funcional de Agente Auxiliar de Creche, que passou a integrar o Quadro de Pessoal de Apoio à Educação. O ingresso ao cargo deu-se através de concurso público, realizado em 2007, constituído de provas e provas de títulos, sendo exigida, a formação mínima em nível fundamental (o que fere a LDBEN 9394/96) e carga horária de 40 horas semanais. A seleção ocorreu regionalmente, isto é, por CRE. Em junho de 2008, o quadro de pessoal das creches públicas do município do Rio de Janeiro passou a contar em sua estrutura, com os novos profissionais egressos do concurso, marcando uma nova trajetória na história dessas instituições. A partir da análise do perfil destes educadores, meu objetivo foi refletir sobre a formação em serviço necessária para atender às especificidades de trabalho com criança de zero a três anos. Estaremos assim, co-participando na implementação de políticas públicas de Educação Infantil da prefeitura quanto à formação em serviço dos agentes auxiliares de creche. Para tanto, propomos três temas comuns e complementares de pesquisa: Inserção das crianças e famílias à creche; Brincar/Brincadeira; Arranjo espacial. Os instrumentos utilizados na pesquisa foram: observação participativa, questionários, e entrevistas. Foram também desenvolvidas, com os educadores, atividades de formação e sessões reflexivas que proporcionem o pleno desenvolvimento profissional desses sujeitos.

RESTful Discovery and Eventing for Service Provisioning in Assisted Living Environments

Service provisioning in assisted living environments faces distinct challenges due to the heterogeneity of networks, access technology, and sensing/actuation devices in such an environment. Existing solutions, such as SOAP-based web services, can interconnect heterogeneous devices and services, and can be published, discovered and invoked dynamically. However, it is considered heavier than what is required in the smart environment-like context and hence suffers from performance degradation. Alternatively, REpresentational State Transfer (REST) has gained much attention from the community and is considered as a lighter and cleaner technology compared to the SOAP-based web services. Since it is simple to publish and use a RESTful web service, more and more service providers are moving toward REST-based solutions, which promote a resource-centric conceptualization as opposed to a service-centric conceptualization. Despite such benefits of REST, the dynamic discovery and eventing of RESTful services are yet considered a major hurdle to utilization of the full potential of REST-based approaches. In this paper, we address this issue, by providing a RESTful discovery and eventing specification and demonstrate it in an assisted living healthcare scenario. We envisage that through this approach, the service provisioning in ambient assisted living or other smart environment settings will be more efficient, timely, and less resource-intensive.

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.

The Long Voyage to Including Sociocultural Analysis in NOAA’s National Marine Fisheries Service

The United States has managed and analyzed its marine fisheries since 1871, and since 1970 via NOAA’s National Marine Fisheries Service (NMFS). As the primary directive moved from aiding fishermen in expanding their operations emphasizing conservation, the government over time recognized that management involves influencing people not fish, and has hired social scientists to complement the biologists who assess fish populations. This change has not always been smooth. We use archival documents and oral histories to trace the development of sociocultural analytic capabilities within NMFS and describe future plans for growing the program. Four points are made. First, NMFS has created the best developed social science program in NOAA. Second, established institutions change slowly; achieving the social science presence in NMFS has taken over 25 years. Third, change needs visionaries and champions with both tenacity and opportunity. Fourth, social science data collection and research helps in making fishery management decisions, but they have also been useful in evaluating the impact and helping with the recovery from Hurricane Katrina. Good work finds other uses.
