Development of site-specific sediment quality guidelines for North and South Atlantic littoral zones: Comparison against national and international sediment quality benchmarks

We aimed to develop site-specific sediment quality guidelines (SQGs) for two estuarine and port zones in Southeastern Brazil (Santos Estuarine System and Paranagua Estuarine System) and three in Southern Spain (Ria of Huelva, Bay of Cadiz, and Bay of Algeciras), and compare these values against national and traditionally used international benchmark values. Site-specific SQGs were derived based on sediment physical-chemical, toxicological, and benthic community data integrated through multivariate analysis. This technique allowed the identification of chemicals of concern and the establishment of effects range correlatively to individual concentrations of contaminants for each site of study. The results revealed that sediments from Santos channel, as well as inner portions of the SES, are considered highly polluted (exceeding SQGs-high) by metals, PAHs and PCBs. High pollution by PAHs and some metals was found in Sao Vicente channel. In PES, sediments from inner portions (proximities of the Ponta do Mix port`s terminal and the Port of Paranagua) are highly polluted by metals and PAHs, including one zone inside the limits of an environmental protection area. In Gulf of Cadiz, SQGs exceedences were found in Ria of Huelva (all analysed metals and PAHs), in the surroundings of the Port of CAdiz (Bay of CAdiz) (metals), and in Bay of Algeciras (Ni and PAHs). The site-specific SQGs derived in this study are more restricted than national SQGs applied in Brazil and Spain, as well as international guidelines. This finding confirms the importance of the development of site-specific SQGs to support the characterisation of sediments and dredged material. The use of the same methodology to derive SQGs in Brazilian and Spanish port zones confirmed the applicability of this technique with an international scope and provided a harmonised methodology for site-specific SQGs derivation.

Molecular Surveillance of the Newcastle Disease Virus in Domestic and Wild Birds on the North Eastern Coast and Amazon Biome of Brazil

Brazil is one of the world's largest countries with a rich diversity of wildlife, including resident and migratory wild birds, which may be natural reservoirs of the Newcastle disease virus (NDV). Because Brazil is a major global exporter of chicken meat, the emergence of such a disease may have a huge negative impact not only on the economy due to trade restrictions and embargoes, but also on the quality of life of the population. Samples were collected from 1,022 asymptomatic domestic and wild birds from the Brazilian coast and the Amazon region using tracheal/cloacal swabs and tested by RT-qPCR. The results showed 7 (0.7%) birds were positive for NDV. The positive samples were then isolated in embryonated chicken eggs and their matrix protein genes were partially sequenced, revealing a low-pathogenicity NDV. This study confirms the maintenance of the velogenic-NDV free status of Brazil.

Construction and validation of an instrument that breaks the silence: the impact of domestic and/or sexual violence on women's health, as shown during climacterium

Objective: The aim of this study was to construct and to validate a measure of the consequences of domestic violence on women's health during climacterium. Methods: A questionnaire was administered at the Outpatient Climacterium Clinic to 124 women aged 40 to 65 years who were the victims of domestic and/or sexual violence (experimental group). They were divided into three groups: (1) those who were victims of violence exclusively during childhood/adolescence, (2) those who were victims of violence exclusively during adulthood, and (3) those who were victims of violence throughout their lives. The instrument included 34 items evaluating the beginning, frequency, and type of violence; the search for health assistance and reporting of the violence; the violence and the number of comorbidities; and violence and the Kupperman Menopausal Index. We also included a control group composed of perimenopausal and postmenopausal women who did not experience any violence (n = 120). Results: The instrument presented a Cronbach alpha = 0.82, good reliability among the examiners (+0.80), and a good possibility of reproducibility. The mean age of menopause was 45.4 years, and the mean age in the control group was 48.1 years. Group 1 showed a mean of 5.1 comorbidities, Group 2 had 4.6, and Group 3 had 4.4. Sexual violence (43.5%) and other types of violence both presented average comorbidities (4.60) but represented a significant impairment in the victim's sexual life. There were significant associations in group 3 and a high Kupperman Menopausal Index score. In the experimental group, 80.6% did not seek health services for the violence they experienced. Conclusions: The questionnaire presented good internal consistency and a validated construction. It can be easily reproduced and is indicated to evaluate the consequences of domestic and/or sexual violence on women's health during climacterium.

Children and teenagers working in artistic labor: Brazilian situation and international examples

This descriptive study about children and adolescents artistic labor verifies the applicable legislation, in Brazil, regarding the participation of children and adolescents in the entertainment industry and in advertising campaigns, as well as the judicial processes about the theme known by the Brazilian Superior Court of Justice up to October, 2010. The results permit to conclude that, due to the lack of specific regulation and general rule of child labor prohibition, the restrictions that tend to protect the health and security of children and adolescents that act in the artistic niche (television, advertising, fashion, movies etc.) have been, in Brazil, at subjective criteria of the judges and, in many cases, in the hands of producers themselves. Brief considerations on how other countries regulate the theme are also presented (the USA, Portugal and Argentina).

Sustentabilidade e cadeia de suprimentos: uma perspectiva comparada de publicações nacionais e internacionais

O objetivo do artigo é apresentar um quadro de referência de conceitos da Gestão da Sustentabilidade na Cadeia de Suprimentos (GSCS) para auxiliar pesquisas futuras na tentativa de integração intra e interorganizacional fundamentada em aspectos da sustentabilidade. Trata-se de um artigo teórico, cujo procedimento metodológico adotado foi o desk research em periódicos da área de gestão e operações, realizado em duas etapas. Na primeira, buscou-se visualizar os estudos da temática em seis importantes periódicos internacionais da área, totalizando 53 artigos entre 1954 e 2009. Esta etapa gerou uma evolução da temática, contribuindo para apontar tendências. Na segunda, foram revisados seis periódicos nacionais da área de administração. Selecionaram-se 11 artigos, publicados entre 1961 e 2009, resultando em um panorama da temática no contexto acadêmico brasileiro. O conceito de GSCS apareceu apenas em 2007, o que mostra a atualidade do tema, embora este seja a junção de temáticas anteriormente estudadas.
