Echoes of time. The mobility of Brazilian researchers and students in Portugal
A investigação que apresentamos, de caráter exploratório, recaiu sobre histórias
biográficas de brasileiros que escolhem Portugal para prosseguir formação e
ou investigação. Procura-se encontrar na sua experiência elos de ligação explicativos
sobre as motivações e os processos que os trazem para Portugal, assim como
as expetativas e os projetos que comportam para os seus futuros e que incluem,
ou não, este país. Temos em conta, especialmente, a forma como essa narrativa
transporta sentidos identitários decorrentes das formas de relacionamento intercultural
e político entre Portugal e Brasil e formas de cooperação implícitas, assim
como mapas representacionais acerca dos lugares de eleição para desenvolvimento
de carreiras científicas e académicas. A nossa pesquisa incide sobre as informações
recolhidas através de um inquérito por questionário e entrevistas realizadas
junto de estudantes e bolseiros brasileiros em Portugal.We present an exploratory study that investigated biographical stories of
Brazilians who choose to continue their education or develop research in Portugal.
We sought to find in their experiences explanatory links connecting the
motivations and processes that bring them to Portugal, as well as the expectations
and projects that they hold for the future, which may include, or not, this country.
We take into account, particularly, the way this narrative carries senses of identity
arising from the forms of intercultural and political relationship between Portugal
and Brazil, as well as implicit forms of cooperation and representations about the
places chosen for the development of scientific and academic careers. Our research
draws on information collected through a survey based on questionnaires and
interviews with Brazilian students and scholarship holders in Portugal.(undefined
NOAA Coastal Change Analysis Program (C-CAP): Guidance for Regional Implementation
EXECUTIVE SUMMARY:
The Coastal Change Analysis Programl (C-CAP) is developing
a nationally standardized database on landcover and habitat change in the coastal regions of the United States. C-CAP is part of the Estuarine Habitat Program (EHP) of NOAA's Coastal Ocean Program (COP). C-CAP inventories coastal submersed habitats, wetland habitats, and adjacent uplands and monitors changes in these habitats on a one- to five-year cycle. This type of information and frequency of detection are required to improve scientific understanding of the linkages of coastal and submersed wetland habitats with adjacent uplands and with the distribution, abundance,
and health of living marine resources. The monitoring
cycle will vary according to the rate and magnitude of
change in each geographic region. Satellite imagery
(primarily Landsat Thematic Mapper), aerial photography,
and field data are interpreted, classified, analyzed,
and integrated with other digital data in a geographic
information system (GIS). The resulting landcover
change databases are disseminated in digital form
for use by anyone wishing to conduct geographic analysis
in the completed regions. C-CAP spatial information on coastal change will be input to EHP conceptual and predictive models to support coastal resource policy planning and analysis. CCAP products will include 1) spatially registered digital databases and images, 2) tabular summaries by state, county, and hydrologic unit, and 3) documentation. Aggregations to larger areas (representing habitats, wildlife refuges, or management districts) will be provided on a case-by-case basis. Ongoing C-CAP research will continue to explore techniques for remote determination of biomass, productivity, and functional status of wetlands and will evaluate new technologies (e.g. remote sensor systems, global positioning systems, image processing algorithms) as they become available. Selected hardcopy land-cover change maps will be produced at local (1:24,000) to regional scales (1:500,000) for distribution. Digital land-cover change data will be provided to users for the cost of reproduction.
Much of the guidance contained in this document was developed through a series of professional workshops
and interagency meetings that focused on a) coastal wetlands and uplands; b) coastal submersed habitat including aquatic beds; c) user needs; d) regional
issues; e) classification schemes; f) change detection
techniques; and g) data quality. Invited participants
included technical and regional experts and representatives
of key State and Federal organizations. Coastal habitat managers and researchers were given an opportunity for review and comment. This document summarizes C-CAP protocols and procedures that are to be used by scientists throughout the United States to develop consistent and reliable coastal change information for input to the C-CAP nationwide database. It also provides useful guidelines for contributors working on related projects. It is considered a working document subject to periodic review and revision.(PDF file contains 104 pages.

Recommendations from Two Citizens’ Juries on the Surgical Management of Obesity
Background: It is important that guidelines and criteria used to prioritise access to bariatric surgery are informed by the values of the tax-paying public in combination with the expertise of healthcare professionals. Citizens’ juries are increasingly used around the world to engage the public in healthcare decision-making. This study investigated citizens’ juries about prioritising patient access to bariatric surgery in two Australian cities. Objectives: The objective of this study is to examine public priorities for government expenditure on the surgical management of obesity developed through either a one or three-day citizen jury. Subjects/Methods: A three-day jury was held in Brisbane and a one-day jury in Adelaide. Jurors were selected in Brisbane (n = 18) and in Adelaide (n = 12) according to pre-specified criteria. Expert witnesses from various medical disciplines and consumers were cross-examined by jurors. Results: The verdicts of the juries were similar in that both juries agreed bariatric surgery was an important option in the management of obesity and related comorbidities. Recommendations about who should receive treatment differed slightly across the juries. Both juries rejected the use of age as a rationing tool, but managed their objections in different ways. Participants’ experiences of the jury process were positive, but our observations suggested that many variables may influence the nature of the final verdict. Conclusions: Citizen’s juries, even when shorter in duration, can be an effective tool to guide the development of health policy and priorities. However, our study has identified a range of variables that should be considered when designing and running a jury and when interpreting the verdict

A Complete Expression Profile of Matrix-Degrading Metalloproteinases in Dupuytren’s Disease
Dupuytren’s disease (DD) is a common fibrotic condition of the palmar fascia, leading to deposition of collagen-rich cords and finger contractions. The metzincin superfamily contains key enzymes in the turnover of collagen and other extracellular matrix macromolecules. A number of broad-spectrum matrix metalloproteinase inhibitors, used in cancer clinical trials, caused side effects of DD-like contractures. We tested the hypothesis that changes in the expression of specific metalloproteinases underlie or contribute to the fibrosis and contracture seen in DD. We collected tissue from patients with DD and used normal palmar fascia as a control. We profiled the expression of the entire matrix metalloproteinase (MMP), tissue inhibitor of metalloproteinases (TIMP), and a disintegrin and metalloproteinase domain with thrombospondin motif (ADAMTS) gene families in these tissues using real-time reverse-transcription polymerase chain reaction. A number of metalloproteinases and inhibitors are regulated in DD. The expression of 3 key collagenases, MMP1, MMP13, and MMP14 is increased significantly in the DD nodule, as is the expression of the collagen biosynthetic enzyme ADAMTS14. The expression of MMP7, an enzyme with broad substrate specificity, is increased in the DD nodule and remains equally expressed in the DD cord. TIMP1 expression is increased significantly in DD nodule compared with normal palmar fascia. This study measured the expression of all MMP, ADAMTS, and TIMP genes in DD. Contraction and fibrosis may result from: (1) increased collagen biosynthesis mediated by increased ADAMTS-14; (2) an increased level of TIMP-1 blocking MMP-1– and MMP-13–mediated collagenolysis; and (3) contraction enabled by MMP-14–mediated pericellular collagenolysis (and potentially MMP-7), which may escape inhibition by TIMP-1. The complete expression profile will provide a knowledge-based approach to novel therapeutics targeting these genes
