Homelessness policies in 8 EU countries: An analysis on Policy formation and implementation

The transnational comparative analysis of social policies is a challenging endeavour for researchers, going beyond the description of the “letter of the law” or policy document regarding similarities and differences concerning content, also requiring the understanding of the dimensions associated with formation and implementation. The overall aim of HOME_EU homelessness policy study is to compare Homelessness Policies from 8 EU Countries on the reduction and reversion of this prevailing social phenomenon, with a particular concern related with the presence of Housing First programmatic measures. The study is composed of a qualitative phase with policy documental analysis and a quantitative phase with a survey sample survey for policy stakeholders on policy implementation. The chapter also offers a critical appraisal on limitations and discusses and recommendations for future research.info:eu-repo/semantics/publishedVersio

Using conceptual maps in physics classes

Concept Maps: Theory, Methodology, Technology Proc. of the First Int. Conference on Concept Mapping A. J. Cañas, J. D. Novak, F. M. González, Eds. Pamplona, Spain 2004This Poster follows, on the one hand, from the long-term use of concept maps in classes by one of the authors, and her reflection upon this use; it follows, on the other hand, from the fact that the declared theme is an important subject in the research being carried out by the other two authors. We begin with a necessarily-brief introduction to meaningful learning and its mechanisms, following Ausubel’s and Novak’s meaningful learning theory; we then refer generically to the concept maps, showing how we have both introduced them to pupils and used them in classrooms, and we conclude by presenting two examples (from the many that we could present) to illustrate not only the use that we have made of them, but also their usefulness. Basically, we will present some ideas that we have elaborated and discussed, and which are applicable in what concerns concept maps, and consequently submit them to discussion with the teachers and researchers present in this meeting

The effects of cyclosporin a and heteropterys tomentosa on the rat liver

Cyclosporin A (CsA) is a widely employed immunosuppressive drug that is associated with several side effects, among then hepatotoxicity. Heteropterys tomentosa is a Brazilian plant efficient in reducing damage caused by CsA on the rat testis and prostate. The aim of this study was to evaluate the effect of CsA and H. tomentosa (administered isolated or simultaneously) on the liver of Wistar rats. The animals were treated daily with water (control), CsA (15mg/kg/day), H. tomentosa infusion or CsA+H. tomentosa, for 21 or 56 days. The treatments did not alter liver morphology or cause fibrosis. H. tomentosa administered for 21 days increased the number of hepatocyte nuclei and Kupffer cell volumetric proportion. After 56 days of treatment, H. tomentosa administration did not alter the parameters analyzed. Biochemical plasma dosages and liver stereology showed impairment caused by CsA-treatment after 21 days; these results were not observed after 56 days of treatment. The simultaneous treatment with CsA and H. tomentosa for 21 or 56 days did not alleviate nor accentuate CsA hepatic effects. The present study showed that the 21 days treatment with CsA caused more alteration to the liver than the 56 days treatment; this could be related to hepatic recovery after the long term treatment871369379FUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULO - FAPESP2011/01160-

Evaluation of a NIR handheld device and PLS-DA for discrimination of six similar amazonian wood species

Supervising wood exploitation can be very challenging due to the existence of many similar species and the reduced number of wood identification experts to meet the demand. There is evidence that valuable endangered wood species are being smuggled disguised as other species. Near infrared spectroscopy (NIRS) and chemometrics has been successfully used to discriminate between Amazonian wood species using high resolution instruments. In this study, a handheld spectrometer was evaluated for the discrimination of six visually similar tropical wood species using PLS-DA. Woods of mahogany (Swietenia macrophylla) and cedar (Cedrela odorata), both high value tropical timber species included in Appendixes II and III of the CITES, respectively; crabwood (Carapa guianensis); cedrinho (Erisma uncinatum); curupixá (Micropholis melinoniana); and jatobá (Hymenea coubaril). The data for model development and validation take into account both laboratory and field measurements. Outlier exclusion was performed based on Hotelling T2, residuals Q and errors in the estimated class values. The efficiency rates were higher than 90% for all species, showing that the handheld NIR combined with PLS-DA succeeded in discriminate between these species. These results stimulate the application of handheld NIR spectrometers in the supervision of wood exploitation, which can contribute to the species preservation

Innovation for Sustainability and Networking

Throughout human history, innovation has been the main factor in adapting humanity to its settings. On the basis of earlier practice, human creativity allows the finding of new, permanent ways to do things. their applications encourage new spaces, new necessities and new lifestyles. Innovation has been an element of human capacities from its earlier stages, but it has been recognized only recently as a clear device of social and economic change

Perspectives on the Trypanosoma cruzi-host cell receptor interaction

Chagas disease is caused by the parasite Trypanosoma cruzi. The critical initial event is the interaction of the trypomastigote form of the parasite with host receptors. This review highlights recent observations concerning these interactions. Some of the key receptors considered are those for thromboxane, bradykinin, and for the nerve growth factor TrKA. Other important receptors such as galectin-3, thrombospondin, and laminin are also discussed. Investigation into the molecular biology and cell biology of host receptors for T. cruzi may provide novel therapeutic targets

Unravelling pine response to Fusarium circinatum through Raman spectroscopy

Pine Pitch Canker (PPC), caused by the fungus Fusarium circinatum, is associated to significant economic and ecological losses worldwide. The effectiveness of PPC monitoring, early detection in nurseries and plantations, and the identification of resistant plant material relies on the development of objective, non-destructive and cost-effective tools. This study analysed the potential of employing Raman Spectroscopy (RS) for the early detection of biochemical changes associated with PPC in Pinus spp. with different susceptibilities to F. circinatum (highly susceptible Pinus radiata vs. relatively-resistant Pinus pinea), while unveiling possible mechanisms of action on these pathosystems. Our results indicate lignin as a key constitutive component of pine resistance against PPC and thus the potential of using this technology for the selection of PPC resistant trees. Moreover, we demonstrate the power of RS-based approaches for the rapid detection of the disease in susceptible species. Early spectral variations were found in P. radiata upon inoculation with F. circinatum from 3 days post-inoculation (dpi) onwards, whereas changes in histological analysis, relative internal stem necrosis measurements, and visual disease symptoms were only visible at 6, 8, and 9-dpi, respectively. These spectral changes have been associated to cell-wall degradation and induction of phenolic compounds synthesis upon infection in P. radiata. Altogether, we believe that RS is an innovative promising tool able to reduce disease detection time in pine species and providing an appealing alternative for the development of new and eco-friendly disease control measures

Genotypes at the APOE and SCA2 loci do not predict the course of multiple sclerosis in patients of Portuguese origin

Prova tipográfica (In Press)Multiple sclerosis (MS) is a demyelinating disease that affects about one in 500 young Europeans. In order to test the previously proposed influence of the APOE and SCA2 loci on susceptibility to MS, we studied these loci in 243 Portuguese patients and 192 healthy controls and both parents of 92 patients. We did not detect any significant difference when APOE and SCA2 allele frequencies of cases and controls were compared, or when we compared cases with different forms of the disease. Disequilibrium of transmission was tested for both loci in the 92 trios, and we did not observe segregation distortion. To test the influence of the APOE o4 and SCA2 22 CAGs alleles on severity of disease, we compared age at onset and progression rate between groups with and without those alleles. We did not observe an association of the o4 or the 22 CAGs alleles with rate of progression in our total patient population; allele o4 was associated with increased rate of progression of MS in a subset of patients with less than 10 years of the disease. However, globally in the Portuguese population, the APOE and SCA2 genes do not seem to be useful in the clinical context as prognostic markers of this disorder.Fundação para a Ciência e a Tecnologia (FCT) - grant SFRH/BD/9111/2002.Serono Portugal
