It has become evident that policies aimed at mitigating the growing water resources and water use conflicts in Brazil are crucial. The municipality of Extrema in Minas Gerais state in Brazil pioneered the first Brazilian municipal PES initiative (Conservador das Aguas program), based on the relationship between forests and the benefits they provide. This study aimed to assess soil loss in the Posses sub-basin, where the Conservador das Aguas program began. Additionally, we aimed to determine the potential that this PES initiative has for soil conservation, as well as to minimize the soil losses as a function of forest area size and location in order to propose a technical approach for implementing PES. In this sense, considering the prescribed conservation practices, land use situation, and soil cover in the Posses sub-basin, we analyzed the effectiveness of the Conservador das Aguas program before and after implementation in relation to reduced soil loss under 36 different land use and soil cover scenarios. We used a geographic information system (GIS) for spatializing and producing different information plans and the Revised Universal Soil Loss Equation (RUSLE) for estimating soil loss. As a result, we found that minimization of soil loss may be obtained by adopting pasture conservation practices. Additionally the expected average soil loss in the Posses sub-basin under conditions of land use and soil cover, before and after implementing the water conservation program was 30.63 and 7.06 Mg ha(-1) year(-1), respectively.

In the study of theoretical trends in Administration, the management of information follows the development of theories of Administration; constant-adaptations are suffered. Information Science area understands and concerns itself with the changes wrought in these endeavour of the knowledge society as new forms of communication and integration. The libraries interact in ways that maximize access to information and facilitate the improvement on their structural environment as strategic approach for your services. The research aims at identifying the requirements and specifications of an information system for knowledge management in the public’s library environment and proposes to achieve a pre-defined structure for the implementation of administration management. The research is conducted with public’s library of the metropolitan region of the North’s Portugal. Portugal libraries are institutions that operate in the social process of their communities reflecting the society and its organic sphere of informational performance. These libraries have developed the organizational theories to make a framework easily for effective management practices and have been using their produced knowledge in the optimization of their actions. In the improvement of systems, theoretical administrative trends become management decisions and result in the ultimate success of the organization. In order to achieve its objectives the study verified an economy based on knowledge management, and its production emphasizes the human capital that permeates the condition of the information in support for the development of communities.

This study investigated the use of library catalogue in Niger Delta University library. The study employed descriptive research method and questionnaire as a research instrument to generate the data. The analysis revealed that 168 (51 percent) of the users were not aware of library catalogue, and 160 (54 percent) had never used the catalogue. The study also showed that 209 (71.7 percent) encountered difficulties in using the catalogue because of lack of proper education and, as a result, 202 (68.7 percent) of the users resolved to used browsing/reading through the shelves method to locate books. The analysis also revealed that 202 (68.7 percent) of users indicated that proper user education was a means to easy catalogue use in the library. Recommendations were made to improve effective catalogue use, including user education, regular orientation programme, and preparation of guidelines on use of the library catalogue.

This paper addresses equity in health and health care in Brazil, examining unjust disparities between women and men, and between women from different social strata, with a focus on services for contraception, abortion and pregnancy. In 2010 women's life expectancy was 77.6 years, men's was 69.7 years. Women are two-thirds of public hospital services users and assess their health status less positively than men. The total fertility rate was 1.8 in 2011, and contraceptive prevalence has been high among women at all income levels. The proportion of sterilizations has decreased; lower-income women are more frequently sterilized. Abortions are mostly illegal; women with more money have better access to safe abortions in private clinics. Poorer women generally self-induce abortion with misoprostol, seeking treatment of complications from public clinics. Institutional violence on the part of health professionals is reported by half of women receiving abortion care and a quarter of women during childbirth. Maternity care is virtually universal. The public sector has fewer caesarean sections, fewer low birth weight babies, and more rooming-in, but excessive episiotomies and inductions. Privacy, continuity of care and companionship during birth are more common in the private sector. To achieve equity, the health system must go beyond universal, unregulated access to technology, and move towards safe, effective and transparent care. (C) 2012 Reproductive Health Matters

We use electronic communication networks for more than simply traditional telecommunications: we access the news, buy goods online, file our taxes, contribute to public debate, and more. As a result, a wider array of privacy interests is implicated for users of electronic communications networks and services. . This development calls into question the scope of electronic communications privacy rules. This paper analyses the scope of these rules, taking into account the rationale and the historic background of the European electronic communications privacy framework. We develop a framework for analysing the scope of electronic communications privacy rules using three approaches: (i) a service-centric approach, (ii) a data-centric approach, and (iii) a value-centric approach. We discuss the strengths and weaknesses of each approach. The current e-Privacy Directive contains a complex blend of the three approaches, which does not seem to be based on a thorough analysis of their strengths and weaknesses. The upcoming review of the directive announced by the European Commission provides an opportunity to improve the scoping of the rules.

Climate, land use and fire are strong determinants of plant diversity, potentially resulting in local extinctions, including rare endemic and economically valuable species. While climate and land use are decisive for vegetation composition and thus the species pool, fire disturbance can lead to landscape fragmentation, affecting the provisioning of important ecosystem services such as timber and raw natural resources. We use multi-proxy palaeoecological data with high taxonomic and temporal resolution across an environmental gradient to assess the long-term impact of major climate shifts, land use and fire disturbance on past vegetation openness and plant diversity (evenness and richness). Evenness of taxa is inferred by calculating the probability of interspecific encounter (PIE) of pollen and spores and species richness by palynological richness (PRI). To account for evenness distortions of PRI, we developed a new palaeodiversity measure, which is evenness-detrended palynological richness (DE-PRI). Reconstructed species richness increases from north to south regardless of time, mirroring the biodiversity increase across the gradient from temperate deciduous to subtropical evergreen vegetation. Climatic changes after the end of the last ice age contributed to biodiversity dynamics, usually by promoting species richness and evenness in response to warming. The data reveal that the promotion of diverse open-land ecosystems increased when human disturbance became determinant, while forests became less diverse. Our results imply that the today’s biodiversity has been shaped by anthropogenic forcing over the millennia. Future management strategies aiming at a successful conservation of biodiversity should therefore consider the millennia-lasting role of anthropogenic fire and human activities.

The natural regulation of the water cycle by tropical montane forests is an important ecosystem service. Within this chapter we focus on water balance and regulation of the water cycle. Differences of rainfall-runoff generation across scales change from a near-surface event water driven system in pristine rainforest-covered micro-catchments to a more groundwater pre-event water dominated one on the mesoscale. The highly dynamic discharges are often correlated with total suspended sediment loads. However, we also observed total suspended sediment peaks at times of low flow, indicating a decoupling of erosion and stream transport and a triggering of landslides not directly related to hydrological processes. We also summarize likely future trends of water-related ecosystem services and expect an increase in human use and benefits of fresh water use whereas changes in water regulation and water purification services remain unchanged on a high level.

BACKGROUND AND STUDY AIMS Colorectal cancer (CRC) incidence ranks third among all cancers in Switzerland. Screening the general population could decrease CRC incidence and mortality. The aim of this study was to analyze the use of the fecal occult blood test (FOBT) and lower gastrointestinal endoscopy in a representative sample of the Swiss population aged ≥ 50 years. METHODS Data were analyzed from the 2007 Swiss Health Interview Survey and the prevalence estimates and 95 % confidence intervals were calculated based on all instances of lower gastrointestinal endoscopy and FOBT use, as well as on their use for CRC screening. Uni- and multivariate logistic regression analyses were performed to describe the association between screening use and sociodemographic characteristics, indicators of healthcare system use, and lifestyle factors. RESULTS In 2007, approximately 36 % of the surveyed people who were aged ≥ 50 years had previously undergone FOBT and approximately 30 % had previously undergone lower gastrointestinal endoscopy. CRC screening use was 7.7 % for FOBT (within the past year) and 6.4 % for lower gastrointestinal endoscopy (within the past 5 years). CRC screening by either method was 13 %. The major determinants of participation in CRC screening were found to be sex (male), physician visits during the past year (one or more), type of health insurance (private), and previous screening for other cancer types. CONCLUSIONS The results of the 2007 Swiss Health Interview Survey indicate rather low levels of FOBT and lower gastrointestinal endoscopy use. Furthermore, the results suggest disparities in the use of CRC screening.

OBJECTIVES Decisions to use condoms are made within partnerships. We examined the associations between inconsistent or no condom use and individual and partnership characteristics. We also examined the relative importance of individual versus partnership factors. METHODS Cross-sectional study of heterosexual individuals enrolled from the sexually transmitted infections (STI) outpatient clinic in Amsterdam, the Netherlands, from May to August 2010. Participants completed a questionnaire about sexual behaviour with the last four partners in the preceding year. Participant and partnership factors associated with inconsistent or no condom use in steady and casual partnerships were identified. RESULTS 2144 individuals were included, reporting 6401 partnerships; 54.7% were female, the median age was 25 (IQR 22-30) years and 79.9% were Dutch. Inconsistent or no condom use occurred in 13.9% of 2387 steady partnerships and in 33.5% of 4014 casual partnerships. There was statistical evidence of associations between inconsistent condom use in steady partnerships and ethnic concordance, longer duration, higher number of sex acts, practising anal sex, and sex-related drug use. In casual partnerships, associations were found with having an older partner, ethnic concordance, longer duration, higher number of sex acts, anal sex, sex-related drug use, ongoing partnerships and concurrency. In multivariable models, partnership factors explained 50.9% of the variance in steady partnerships and 70.1% in casual partnerships compared with 10.5% and 15.4% respectively for individual factors. CONCLUSIONS Among heterosexual STI clinic attendees in Amsterdam, partnership factors are more important factors related with inconsistent condom use than characteristics of the individual.

An interdisciplinary research unit consisting of 30 teams in the natural, economic and social sciences analyzed biodiversity and ecosystem services of a mountain rainforest ecosystem in the hotspot of the tropical Andes, with special reference to past, current and future environmental changes. The group assessed ecosystem services using data from ecological field and scenario-driven model experiments, and with the help of comparative field surveys of the natural forest and its anthropogenic replacement system for agriculture. The book offers insights into the impacts of environmental change on various service categories mentioned in the Millennium Ecosystem Assessment (2005): cultural, regulating, supporting and provisioning ecosystem services. Examples focus on biodiversity of plants and animals including trophic networks, and abiotic/biotic parameters such as soils, regional climate, water, nutrient and sediment cycles. The types of threats considered include land use and climate changes, as well as atmospheric fertilization. In terms of regulating and provisioning services, the emphasis is primarily on water regulation and supply as well as climate regulation and carbon sequestration. With regard to provisioning services, the synthesis of the book provides science-based recommendations for a sustainable land use portfolio including several options such as forestry, pasture management and the practices of indigenous peoples. In closing, the authors show how they integrated the local society by pursuing capacity building in compliance with the CBD-ABS (Convention on Biological Diversity - Access and Benefit Sharing), in the form of education and knowledge transfer for application.

Given the increased awareness and attention to human trafficking, including the establishment of federal laws and policies, federally funded task forces that provide law enforcement responses, and specialized victim services, it is important to assess the impact of these procedures and services on survivors/victims of international human trafficking and their immigrant children. By federal definition, certified victims of international human trafficking are eligible for all services provided to refugees in this country, including reunification with their minor children. This research is based on a qualitative study conducted in Austin and Houston, Texas with human trafficking victims/survivors. The project’s goal was to gain an understanding of the needs of human trafficking survivors after their rescue, their overall integration into American life, and the subsequent needs of their immigrant children after reunification. The project objectives examined the factors that either promote or hinder self-sufficiency, the determination of social service needs, and policy and practice recommendations to strengthen survivors, their children and their families living both locally and abroad. For this project, nine (n = 9) in-depth interviews were conducted with adult foreign-born victims of human trafficking. Researchers gathered data using a semi-structured questionnaire that queried about factors that promote or hinder victims’ services and needs. Interviews were conducted in participants’ homes using bilingual research staff and/or trained interpreters, were digitally-recorded, and subsequently transcribed. Participation in this study was completely voluntary. Specific steps were taken to ensure that the participants’ identities were protected. Open coding of data was utilized and the data were subsequently organized or grouped into properties and later developed into contextual themes around the research questions. The findings are grounded with the use of direct quotes from participants. As a result of progressive U.S. policy, many victims of human trafficking are being reunited with their minor children. Immigrant children are one of the largest and fastest growing populations in the U.S. and for a variety of reasons are vulnerable to exploitation. Research also indicates that victims of trafficking are identified by traffickers because of their perceived “vulnerabilities” or lack of opportunities (Clark, 2003). Therefore, it is important that practices and policies are developed to address the unique needs of these families with an eye toward positive outcomes for parent and child safety and well-being. Social service providers are provided a toolkit that may be utilized before and during the reunification period.
