La creciente utilización del comercio electrónico y la necesidad de generar soluciones eficaces a problemas como la congestión vehicular y la distribución física de mercaderías, están generando un nuevo escenario para el transporte, principalmente para el urbano. Es por ello que la incorporación de las nuevas tecnologías de información y telecomunicaciones no sólo representa un reto estratégico para aprovechar las ventajas de la desregulación de los mercados y apertura de las economías, sino que es una necesidad perentoria para el sector.La presente edición del Boletín se basa en un estudio relacionado con la aplicación de las tecnologías de información y telecomunicaciones en el transporte urbano y vial, que viene desarrollando la Unidad de Transporte de la CEPAL. Aún cuando el estudio se centra en el impacto de dichas tecnologías en las áreas urbana y vial, sus reflexiones, análisis y conclusiones son también aplicables en otras áreas del sector transporte.

Analisa a problemática dos transportes urbanos, no contexto da Região Amazônica. O estudo tem o objetivo de descrever e analisar o transporte de moto-táxi nas cidades de Castanhal, no estado do Pará, e Tefé, no estado do Amazonas, como uma amostra de uma realidade dessa Região, frente às necessidades da produção (indústria privada de motocicleta) e da reprodução (grupo de pessoas). O estudo foi: a) exploratório, porque há pouco conhecimento acumulado e sistematizado sobre o tema; b) explanatório, em razão da busca de relações entre as variáveis; e c) descritivo, pelo motivo de que se estimou freqüências de elementos com determinada propriedade ou característica quantitativa. A pesquisa empírica obedece a um plano amostral. A busca por conhecimento sobre o transporte alternativo se deu por meio da pesquisa bibliográfica. A conclusão desta exposição científica é que a ausência de políticas públicas de transporte urbano em um contexto de desestruturação do mercado de trabalho contribui para o surgimento de serviços de transportes inadequados. Esses serviços têm se constituído, muitas vezes, numa única alternativa de transporte urbano, inadequado pela perspectiva da segurança, e também numa única oportunidade de trabalho, porém excludente do rol de benefícios capaz de reduzir os riscos sociais dos trabalhadores. Neste sentido, aceita-se a hipótese de que a crescente necessidade por transporte alternativo tem se justificado pela ausência de adequadas políticas públicas de transporte e emprego.

Esse trabalho tem por objetivo, mostrar a evolução do sistema de transporte coletivo intermunicipal do Estado de São Paulo. Nesse sentido, partimos do processo de industrialização e nacionalização da indústria automobilística. Procuramos também mostrar a evolução do Departamento de Estradas e Rodagem [DER], no papel de direcionador e gerenciador do sistema. Nesse processo, detalhamos o papel de todos os governos do Estado de São Paulo, na implantação de sistema viário estadual [1950-2006]. Também procuramos demonstrar o surgimento dos principais grupos que monopolizam cada vez mais o setor dos transportes coletivo intermunicipal. Assim, vamos comprovar a tese de que as empresas do transporte coletivo intermunicipal estão utilizando as linhas suburbanas para fazer frente ao grande avanço do transporte clandestino intermunicipal no Estado de São Paulo.

The work consists of the historical city of Guaratinguetá, as well as data on their quality of life, economic development and population, transportation in Brazil and the transportation system of the city serving as a basis to support the development of the urban network. The urban fabric of the city was raised with plants of the city in different years, documents obtained by the Museum and Hall of Frei Galvão Guaratinguetá well to check the form of land use and growth drivers of the city over time. We studied also the main access roads to the city by focusing on an approach that has been the subject of a proposed urban intervention. A direct interview was performed and recorded with one of those responsible for planning the urban fabric of the city in order to gather information on the historical development, the future possibilities of interventions in the urban as well as problems encountered and other curiosities. Through the study it was observed that the urban grid Guaratinguetá developing a planned since 1970 and that the highlights of most cities in the Paraíba Valley. The work is grounded in concepts of sustainable city and also in quantitative and qualitative data from sectors responsible

This work shows the importance of taking a good organization of space for the improvement of urban public transport. The model of urban transport is used improperly aggravating factor that generates diseconomies to society. The reduction of the use of public transport, degradation of environmental conditions, chronic congestion, poor accessibility and high rates of traffic accidents are common in many cities. The case study will be done in Jundiaí - SP, where actions were taken to try to reverse this situation of crisis in urban transport, as the change in transport network system. Will analyze the proposals adopted for the implementation of the new network model, steps taken, questionnaires and results from these studies. Verifying the effectiveness of the new transport network model adopted and its reflection with users, those who use the transportation and / or who directly suffer the influences this

For decades the Companhia Tróleibus de Araraquara was a national reference in public transportion, but in recent years it is in a process of bankruptcy and scrapping, characteristics of privatizing processes that has been occurring worldwide since the rise of neoliberal ideas. This monography is centered on the finance analysis of CTA to investigate what reasons led the public company to come in the current financial scenario, what are the interests that exist to privatize a public company and which consequences the sale of the of public companies have for a country of subordinate capitalism like Brazil. Most Brazilian cities are in an urban collapse due to the lack of public policies for public transportation and bulky incentives for private transportation. Furthermore, this monography aims to contribute for the study of urban mobility and point out if privatization is a way to improve life in the cities

O objetivo desse artigo é apresentar as características gerais de uma nova metodologia para planejamento energético urbano, detalhando os procedimentos para integração de condicionantes de morfologia urbana, que constitui a primeira etapa de aplicação metodológica. Esta abordagem é inovadora e focada na integração de estratégias e soluções em morfologia e mobilidade urbanas, edifícios, energia e meio ambiente para planejamento de áreas em desenvolvimento urbano, novas ou a serem requalificadas, na escala de distritos, bairros e unidades de vizinhança. A análise dos resultados da aplicação metodológica no caso da operação urbana Água Branca indicou que a ocupação urbana por edificações e as densidades construída e populacional necessitavam ser compatibilizadas com a área livre requerida ao adequado dimensionamento da seção viária, no que tange a aspectos de climatologia e de provimento de infraestrutura e demanda para mobilidade urbana. Esta era uma premissa para o aproveitamento da luz e da energia solar em edificações e para que o sistema de transporte urbano fosse mais funcional e energeticamente mais eficiente.

OBJECTIVES: To investigate epidemiological, social, diagnostic and economic aspects of chlamydia screening in non-genitourinary medicine settings. METHODS: Linked studies around a cross-sectional population-based survey of adult men and women invited to collect urine and (for women) vulvovaginal swab specimens at home and mail these to a laboratory for testing for Chlamydia trachomatis. Specimens were used in laboratory evaluations of an amplified enzyme immunoassay (PCE EIA) and two nucleic acid amplification tests [Cobas polymerase chain reaction (PCR), Becton Dickinson strand displacement amplification (SDA)]. Chlamydia-positive cases and two negative controls completed a risk factor questionnaire. Chlamydia-positive cases were invited into a randomised controlled trial of partner notification strategies. Samples of individuals testing negative completed psychological questionnaires before and after screening. In-depth interviews were conducted at all stages of screening. Chlamydia transmission and cost-effectiveness of screening were investigated in a transmission dynamic model. SETTING AND PARTICIPANTS: General population in the Bristol and Birmingham areas of England. In total, 19,773 women and men aged 16-39 years were randomly selected from 27 general practice lists. RESULTS: Screening invitations reached 73% (14,382/19,773). Uptake (4731 participants), weighted for sampling, was 39.5% (95% CI 37.7, 40.8%) in women and 29.5% (95% CI 28.0, 31.0%) in men aged 16-39 years. Chlamydia prevalence (219 positive results) in 16-24 year olds was 6.2% (95% CI 4.9, 7.8%) in women and 5.3% (95% CI 4.4, 6.3%) in men. The case-control study did not identify any additional factors that would help target screening. Screening did not adversely affect anxiety, depression or self-esteem. Participants welcomed the convenience and privacy of home-sampling. The relative sensitivity of PCR on male urine specimens was 100% (95% CI 89.1, 100%). The combined relative sensitivities of PCR and SDA using female urine and vulvovaginal swabs were 91.8% (86.1, 95.7, 134/146) and 97.3% (93.1, 99.2%, 142/146). A total of 140 people (74% of eligible) participated in the randomised trial. Compared with referral to a genitourinary medicine clinic, partner notification by practice nurses resulted in 12.4% (95% CI -3.7, 28.6%) more patients with at least one partner treated and 22.0% (95% CI 6.1, 37.8%) more patients with all partners treated. The health service and patients costs (2005 prices) of home-based postal chlamydia screening were 21.47 pounds (95% CI 19.91 pounds, 25.99) per screening invitation and 28.56 pounds (95% CI 22.10 pounds, 30.43) per accepted offer. Preliminary modelling found an incremental cost-effectiveness ratio (2003 prices) comparing screening men and women annually to no screening in the base case of 27,000 pounds/major outcome averted at 8 years. If estimated screening uptake and pelvic inflammatory disease incidence were increased, the cost-effectiveness ratio fell to 3700 pounds/major outcome averted. CONCLUSIONS: Proactive screening for chlamydia in women and men using home-collected specimens was feasible and acceptable. Chlamydia prevalence rates in men and women in the general population are similar. Nucleic acid amplification tests can be used on first-catch urine specimens and vulvovaginal swabs. The administrative costs of proactive screening were similar to those for opportunistic screening. Using empirical estimates of screening uptake and incidence of complications, screening was not cost-effective.

This paper investigates economic aspects of marine protected areas (MPAs) that are closely related to the underlying marine biota. Many marine scientists recognize that enough is now known about the marine biology for the scientific siting of MPAs to protect marine environments that create associated economic values. Marine scientists have identified several objectives of MPAs. These include protection of genetic and biodiversity, increase in population levels and structures (e.g., age, size, fecundity), enrichment of ecosystems by promoting species interactions, and the protection of continental shelf landscapes from invasive human actions. Indeed, some marine scientists and fisheries economists view MPAs as an 'insurance policy' against over-fishing and other human uses of oceanic resources that have damaged so many of the world's fisheries. The economic analysis presented here pays attention to optimal zoning, policies to maintain sustainable economic rents, and the optimal policing of MPAs.
