Os peregrinos da cidade são: representações sociais de “sem-abrigo” emanadas pela sociedade civil lisboeta

Tomando por noção de espaço público o ambiente ou o território da vida social, que medeia entre a esfera privada e a autoridade pública, onde os cidadãos e as pessoas em geral podem encontrar-se livremente para tocarem ideias, conversarem, passearem, interagirem uns com os outros dentro dos limites impostos pela civilidade pública. E por ‘sem abrigo’ a situação generalizada de vivências que têm em comum o impedimento colectivo ou subjectivo do acesso a uma habitação. Habitação entendida não tanto como casa de família mas como alojamento, encarado como residência ou organização sedentária do espaço. O texto que se apresenta aborda o tema da responsabilização, organização e ocupação do espaço público com base nas representações sociais emanadas pelos representantes de algumas das organizações da sociedade civil lisboeta, que orientam a sua acção para a problçemática daqueles que fazem do espaço público o seu ‘domicílio’.

Deep ocean species. The little that is known mostly comes from collected specimens. Comment on L.A. Rocha et al. Letter "Specimen collection: An essential tool" (23 May, 344: 814).

Deep Ocean Species. The little that is known mostly comes from collected specimens. L.A. Rocha et al. Letter "Specimen collection: An essential tool" (23 May, 344: 814) brilliantly discuss the importance of specimen collection and present the evolution of collecting since the mid-19th century until our present strict codes and conducts. However, it is also important to emphasize the fact that the vast majority of deep ocean macro-organisms are only known to us because of collection and this is a strong argument that should be present in our actions as scientists. If the deep is considered the least known of Earth’s habitats (1% or so according to recent estimates) then what awesome collection of yet to discover species are still there to be properly described? As the authors point citing (1), something around 86% of species remain unknown. Voucher specimens are fundamental for the reasons pointed out and perhaps the vast depths of the World’s oceans are the best example of that importance. The resumed report of 2010 Census of Marine Life (2) showed that among the millions of specimens collected in both familiar and seldom-explored waters, the Census found more than 6,000 potentially new species and completed formal descriptions of more than 1,200 of them. It also found that a number of rare species are in fact common. Voucher specimens are essential and, again agreeing with L.A. Rocha et al. Letter (see above), the modern approach for collecting will not be a cause for extinctions but instead a valuable tool for knowledge, description and even, as seen above, a way to find out that supposed rare species may not be that rare and even prove to reach abundant populations.

Patterns, mathematics and culture : the search for symmetry in Azorean sidewalks and traditional crafts

In the hustle and bustle of daily life, how often do we stop to pay attention to the tiny details around us, some of them right beneath our feet? Such is the case of interesting decorative patterns that can be found in squares and sidewalks beautified by the traditional Portuguese pavement. Its most common colors are the black and the white of the basalt and the limestone used; the result is a large variety and richness in patterns. No doubt, it is worth devoting some of our time enjoying the lovely Portuguese pavement, a true worldwide attraction. The interesting patterns found on the Azorean handicrafts are as fascinating and substantial from the cultural point of view. Patterns existing in the sidewalks and crafts can be studied from the mathematical point of view, thus allowing a thorough and rigorous cataloguing of such heritage. The mathematical classification is based on the concept of symmetry, a unifying principle of geometry. Symmetry is a unique tool for helping us relate things that at first glance may appear to have no common ground at all. By interlacing different fields of endeavor, the mathematical approach to sidewalks and crafts is particularly interesting, and an excellent source of inspiration for the development of highly motivated recreational activities. This text is an invitation to visit the nine islands of the Azores and to identify a wide range of patterns, namely rosettes and friezes, by getting to know different arts and crafts and sidewalks.

Paleolítico médio em Galapos (Arrábida)

Quartz (and silex) lithic artifacts collected at Galapos (Creiro), in the southern part of lhe Serra da Arrábida, Portugal, are described. These artifacts are characteristic of the Middle Paleolithic (Mousterian). This new locality reinforces lhe evidences for an important human occupation of this region at those times, as previously shown by the study of the Figueira Brava cave.

Envelhecer: ser e estar - Projeto de intervenção num lar de idosos.

O presente documento reflete o percurso do desenho e do desenvolvimento de um projeto de Educação e Intervenção Social num Lar de idosos. Com base numa metodologia de Investigação-Ação Participativa, que privilegia os discursos, perceções e vivências dos atores sociais que integram esta realidade, procurou-se identificar os problemas e as necessidades. O conhecimento coconstruído com os idosos e profissionais da instituição permitiram a conceção e desenvolvimento do projeto “Envelhecer: ser e estar” que assentou, essencialmente, nas necessidades de (re) ativar e fortalecer as relações interpessoais, fomentar momentos de partilha, convívio, diálogo, discussão, negociação e participação, bem como, na urgência de envolver as pessoas na organização e ocupação do seu tempo livre promovendo a participação, o convívio e o lazer entre os idosos. Sendo um projeto das pessoas e com as pessoas, foram pensadas e planeadas ações e atividades que dessem resposta aos objetivos a que o projeto se propunha na tentativa de transformar e mudar os problemas e necessidades identificados pelos participantes. O projeto possibilitou, desta forma, iniciar um processo que permitiu fortalecer as relações entre os idosos, bem como envolvê-los na organização e participação das atividades do seu tempo livre, resultando num processo de transformação pessoal, grupal e institucional de permanente e contínua construção

Aspectos ecológicos de Simulium goeldii (Diptera: Simuliidae): relação entre substrato e densidade de larvas

The distribution of larvae of Simulium goeldii was studies in four streams in upland tropical forest near Manaus, Amazonas, Brazil. In each month 32 points were sampled, each with an area of 30 x 50 cm. The areas of all substrates available were measured at each point. The larvae of S. goeldii were collected and later counted for all substrate types where larvae of this species were found. The available substrates were classified into eight types: dry leaves, green leaves, branches, fruits, detritus, rocks and sand; anly the first four types had larvae present. The Kruskal-Wallis test and analysis of variance indicated that the larvae occupy these substrates differently; the Newman-Keuls identified the following differences in intensity of occupation of the susbstrates: branchs differ from roots, dry leaves and green leaves, and green leaves differ from roots and dry leaves. The highest density of larvae was observed on green leaves. However, because the most abundant substrates in the study area were roots and dry leaves, I suggest that the latter two substrates are the most important ones for the esteblishment of this population of S. goeldii.

Species delimitation: A case study in a problematic ant taxon

Species delimitation has been invigorated as a discipline in systematics by an influx of new character sets, analytical methods, and conceptual advances. We use genetic data from 68 markers, combined with distributional, bioclimatic, and coloration information, to hypothesize boundaries of evolutionarily independent lineages (species) within the widespread and highly variable nominal fire ant species Solenopsis saevissima, a member of a species group containing invasive pests as well as species that are models for ecological and evolutionary research. Our integrated approach uses diverse methods of analysis to sequentially test whether populations meet specific operational criteria (contingent properties) for candidacy as morphologically cryptic species, including genetic clustering, monophyly, reproductive isolation, and occupation of distinctive niche space. We hypothesize that nominal S. saevissima comprises at least 4-6 previously unrecognized species, including several pairs whose parapatric distributions implicate the development of intrinsic premating or postmating barriers to gene flow. Our genetic data further suggest that regional genetic differentiation in S. saevissima has been influenced by hybridization with other nominal species occurring in sympatry or parapatry, including the quite distantly related Solenopsis geminata. The results of this study illustrate the importance of employing different classes of genetic data (coding and noncoding regions and nuclear and mitochondrial DNA [mtDNA] markers), different methods of genetic data analysis (tree-based and non-tree based methods), and different sources of data (genetic, morphological, and ecological data) to explicitly test various operational criteria for species boundaries in clades of recently diverged lineages, while warning against over reliance on any single data type (e.g., mtDNA sequence variation) when drawing inferences.

Die Säuglingssterblichkeit in der Schweiz: multivariate Betrachtung. [Perinatal mortality in Switzerland: a multivariate analysis]

A regression analysis using a linked file of all Swiss births und perinatal deaths 1979-1981 showed a significant relation between birthweight and canton. Sex of infant and multiplicity of birth were significant, too. For live births, marital and socio-economic status of mother and father relate to birthweight. Logistic regressions brought out relationships between the risk of stillbirth and occupation of father, nationality and marital status of mother, apart from birthweight. For live births, only sex and (weakly) marital status and rank of the child were influencial after correction for birthweight.

Forensic science - A true science ?

While the US jurisprudence of the 1993 Daubert requires judges to question not only the methodology behind, but also the principles governing, a body of knowledge to qualify it as scientific, can forensic science, based on Locard's and Kirk's Principles, pretend to this higher status in the courtroom ? Moving away from the disputable American legal debate, this historical and philosophical study will screen the relevance of the different logical epistemologies to recognize the scientific status of forensic science. As a consequence, the authors are supporting a call for its recognition as a science of its own, defined as the science of identifying and associating traces for investigative and security purposes, based o its fundamental principles and the case assesment and interpretation process that follows with its specific and relevant mode of inference.
