Pequenas deficiências, deficientes profundos

Design para a deficiência, Design de reabilitação, Accessible Design, human-centred Design, usar-centred Design, Design Universal, Design para todos, Design Inclusivo – estes termos têm, ao longo dos últimos trinta anos, vindo a caracterizar uma tendência na abordagem do Design que passou de tentar compreender os problemas de acessibilidade em design a pessoas com deficiência e definir estratégias para aumentar a sua usabilidade (Vanderheiden & Vanderheiden, 1992) para a necessidade de compreender a forma como os produtos excluem utilizadores e procurar formas de eliminar essa exclusão e assim produzir produtos e serviços mais acessíveis. É um movimento que busca centrar o Design na pessoa humana, procurando incluir todos.

O Supervisor como mediador no processo do desenvolvimento pessoal e profissional do professor : do ideal ao real na escola do séc. XXI em Portugal

O presente estudo de investigação visa percepcionar o papel e o trabalho de um supervisor pedagógico na escola portuguesa que possibilite compreender os equívocos e deturpação ligados ao papel do supervisor, quer por quem exerce a função quer por aqueles que são supervisionados. A revisão da literatura foi orientada no sentido de definir a acção e competências do supervisor e os efeitos no desenvolvimento pessoal e profissional do professor avaliado num contexto de uma escola aprendente ou reflexiva, segundo algumas abordagens mais modernas, que gera um trabalho colaborativo entre pares e leva a melhoria do processo ensino-aprendizagem. Analisaram-se desta forma quais os aspectos mais relevantes para nomeação do supervisor, competências e trabalho a desenvolver por este e efeitos no desenvolvimento pessoal e profissional do professor supervisionado e ainda as dificuldades sentidas na concretização da supervisão pedagógica. A investigação decorreu numa Escola do concelho de Matosinhos, recorreu-se a procedimentos metodológicos quantitativos através de inquéritos por questionário aplicados aos professores Relatores/Supervisores e aos professores Avaliados/Supervisionados. Desta investigação ressalta um desfasamento entre os subgrupos inquiridos, sobretudo em relação aos aspectos a ter em conta para sua nomeação, perfil e competências inerentes à função, e no trabalho a desenvolver e desenvolvido pelo Relator/Supervisor.

Formação continuada de professores e mudança na prática pedagógica na sala de aula

O presente estudo trata da formação continuada com foco na prática pedagógica do professor na sala de aula, tendo como objetivo maior analisar se a formação continuada ofertada pela rede municipal de ensino de Itupiranga, estado do Pará, tem contribuído para a mudança da prática do professor na sala de aula. No referencial teórico autores como Nóvoa (2007, 2009), Tardif (2002), Romanowski (2010), Alarcão (2001, 2007), Lüdke (2004) contribuem com suas pesquisas no sentido do entendimento sobre a prática do professor e do processo de formação continuada docente. A pesquisa incorreu sobre um grupo de docentes e de formadores de professores atuantes em cursos, programas e/ou projetos de formação continuada ofertados pela rede municipal de ensino, sendo alvo apenas os envolvidos entre o período de 2005 a 2012. A metodologia de abordagem qualitativa aliados a dados quantitativos desta pesquisa foi realizada a partir de estudos de Bignardi (2009), Oliveira (2007), Bogdan e Bicklen (1994). Optou-se pela aplicação de questionário e entrevista; seguido para uma análise de conteúdo profunda dos dados coletados que apontam que a formação continuada de professores realizada em âmbito municipal contribui de forma significativa para que haja mudança na prática pedagógica dos docentes, os respondentes destacaram três aspectos considerados como alteração de suas práticas, o primeiro está relacionado ao entendimento sobre o reconhecimento e identificação dos níveis de desenvolvimento da leitura e escrita dos educandos; o segundo refere –se ao não uso de cartilhas e de sílabas soltas no processo de alfabetização, as quais foram substituídas por textos, por acreditarem que estes viabilizam tanto o processo de decodificação, identificação de palavras quanto o letramento propriamente dito, o terceiro aspecto demonstra que a mudança ocorreu quando começaram a planejar, de forma coletiva, vários projetos didáticos e sequências didáticas envolvendo os vários gêneros textuais levando em consideração aquilo que o educando já sabe para aprender o que ainda não sabe. Parte significativa dos docentes concordam que a formação continuada por eles frequentada alterou sua forma de atuação em sala de aula, entretanto, surgem outros questionamentos que apontam para a continuidade de pesquisa desta temática.

O círculo da escrita : o texto argumentativo e a consciência (meta)linguística no ensino secundário

O projeto que se apresenta tem por finalidade investigar processos de aperfeiçoamento da competência de escrita do texto argumentativo de alunos do Ensino Secundário. Considerou-se as contribuições convergentes das teorias e técnicas da psicologia cognitiva e de perspetivas sociais da linguagem. Em consequência, associou-se o modelo de revisão de Hayes e Flower (1983; 1980), e de Hayes, Flower, Schriver, Stratman e Carey (1987), ao modelo de análise do discurso de Bronckart (2004; 1996) e à proposta linguística de Adam (2006; 1992). A hipótese que sustenta a investigação é que a consciência (meta)linguística pode facilitar a revisão textual e o aperfeiçoamento da competência de escrita de textos argumentativos, em contexto de Oficina de Escrita. A investigação conjugou duas fases. Na fase intensiva do estudo de caso, os alunos do 11.º ano de Português de uma Escola do Porto progrediram, através de trabalho continuado em Oficina de Escrita. Após a experiência, mesmo alunos com dificuldades revelaram domínio de metalinguagem, mais consciência (meta)linguística na revisão e autorregulação da sua aprendizagem. Na fase extensiva, foi aplicado um inquérito por questionário a uma amostra probabilística de professores do Secundário, igualmente do Porto. Os docentes valorizaram os aspetos supracitados, bem como a leitura de textos argumentativos e o treino do conhecimento explícito da língua. Contudo, em triangulação, as respostas indiciam um ensino centrado no professor, pouco aberto a projetos de escrita, a novas tecnologias e à divulgação de textos à Escola e ao meio. Os resultados indicam que a competência de escrita de textos argumentativos é passível de aperfeiçoamento em Oficina de Escrita, através de interiorização do género textual e aprofundamento da competência (meta)linguística. No contexto do estudo, comprova-se a influência de um treino de escrita inserido em Projetos de Escola, tendo o aluno como sujeito da sua própria aprendizagem, em interação com o meio.

Global Acceleration and Dispossesion: Regression in the Right to Life and Public Health during Ecuador’s Neoliberal Decades

The present essay’s central argument or hypothesis is, consequently, that the mechanisms accelerating a wealth concentrating and exclusionary economy centred on the benefit and overprotection of big business—with a corresponding plundering of resources that are vital for life—generated forms of loss and regression in the right to healthcare and the dismantling of institutional protections. These are all expressed in indicators from 1990-2005, which point not only to the deterioration of healthcare programs and services but also to the undermining of the general conditions of life (social reproduction) and, in contrast to the reports and predictions of the era’s governments, a stagnation or deterioration in health indicators, especially for those most sensitive to the crisis. The present study’s argument is linked together across distinct chapters. First, we undertake the necessary clarification of the categories central to the understanding of a complex issue; clarifying the concept of health itself and its determinants, emphasizing the necessity of taking on an integral understanding as a fundamental prerequisite to unravelling what documents and reports from this era either leave unsaid or distort. Based on that analysis, we will explain the harmful effects of global economic acceleration, the monopolization and pillaging of strategic healthcare goods; not only those which directly place obstacles on the access to health services, but also those like the destructuration of small economies, linked to the impoverishment and worsening of living modes. Thinking epidemiologically, we intend to show signs of the deterioration of broad collectivities’ ways of life as a result of the mechanisms of acceleration and pillage. We will then collect disparate evidence of the deterioration of human health and ecosystems to, finally, establish the most urgent conclusions about this unfortunate period of our social and medical history.

How well do regional or national Breeding Bird Survey data predict songbird population trends at an intact boreal site?

A study to monitor boreal songbird trends was initiated in 1998 in a relatively undisturbed and remote part of the boreal forest in the Northwest Territories, Canada. Eight years of point count data were collected over the 14 years of the study, 1998-2011. Trends were estimated for 50 bird species using generalized linear mixed-effects models, with random effects to account for temporal (repeat sampling within years) and spatial (stations within stands) autocorrelation and variability associated with multiple observers. We tested whether regional and national Breeding Bird Survey (BBS) trends could, on average, predict trends in our study area. Significant increases in our study area outnumbered decreases by 12 species to 6, an opposite pattern compared to Alberta (6 versus 15, respectively) and Canada (9 versus 20). Twenty-two species with relatively precise trend estimates (precision to detect > 30% decline in 10 years; observed SE ≤ 3.7%/year) showed nonsignificant trends, similar to Alberta (24) and Canada (20). Precision-weighted trends for a sample of 19 species with both reliable trends at our site and small portions of their range covered by BBS in Canada were, on average, more negative for Alberta (1.34% per year lower) and for Canada (1.15% per year lower) relative to Fort Liard, though 95% credible intervals still contained zero. We suggest that part of the differences could be attributable to local resource pulses (insect outbreak). However, we also suggest that the tendency for BBS route coverage to disproportionately sample more southerly, developed areas in the boreal forest could result in BBS trends that are not representative of range-wide trends for species whose range is centred farther north.

Occurrence of Kelvin-Helmholtz Billows in Sea-breeze Circulations

Centred at the interface between the sea-breeze and the return flow aloft, Kelvin-Helmholtz billows (KHB) are an important feature of the turbulent structure of some sea-breeze circulations (SBCs). In other SBCs, there are no prominent KHBs observed. Factors governing the appearance of billows are determined from a database of 139 sea breezes, constructed from two years of summertime surface observations at a site on the south coast of England. Post-frontal oscillations occur in the surface data for some SBCs and are interpreted as indicating possible KHBs aloft. The SBCs are formed under a wide range of synoptic conditions, enabling various measures of possible billow occurrence to be related to properties of the large-scale, ambient flow. Consistent with laboratory experiments of density currents, KHBs are suppressed for propagation into a head wind and enhanced with a tail wind. They are also found to be enhanced for stronger ambient wind speeds, while large-scale coast-parallel flow is effective in suppressing the billows.

Diversity and difference in the everyday lives of Ugandan street children: The significance of age and gender for understanding the use of space

Childhood is characterised by diversity and difference across and within societies. Street children have a unique relationship to the urban environment evident through their use of the city. The everyday geographies that street children produce are diversified through the spaces they frequent and the activities they engage in. Drawing on a range of children-centred qualitative methods, this article focuses on street children's use of urban space in Kampala, Uganda. The article demonstrates the importance of considering variables such as gender and age in the analysis of street children's socio-spatial experiences, which, to date, have rarely been considered in other accounts of street children's lives. In addition the article highlights the need for also including street children's individuality and agency into understanding their use of space. The article concludes by arguing for policies to be sensitive to the diversity that characterises street children's lives and calls for a more nuanced approach where policies are designed to accommodate street children's age and gender differences, and their individual needs, interests and abilities.

Modelling habitat selection and distribution of the critically endangered Jerdon's courser Rhinoptilus bitorquatus in scrub jungle: an application of a new tracking method

1. Jerdon's courser Rhinoptilus bitorquatus is a nocturnally active cursorial bird that is only known to occur in a small area of scrub jungle in Andhra Pradesh, India, and is listed as critically endangered by the IUCN. Information on its habitat requirements is needed urgently to underpin conservation measures. We quantified the habitat features that correlated with the use of different areas of scrub jungle by Jerdon's coursers, and developed a model to map potentially suitable habitat over large areas from satellite imagery and facilitate the design of surveys of Jerdon's courser distribution. 2. We used 11 arrays of 5-m long tracking strips consisting of smoothed fine soil to detect the footprints of Jerdon's coursers, and measured tracking rates (tracking events per strip night). We counted the number of bushes and trees, and described other attributes of vegetation and substrate in a 10-m square plot centred on each strip. We obtained reflectance data from Landsat 7 satellite imagery for the pixel within which each strip lay. 3. We used logistic regression models to describe the relationship between tracking rate by Jerdon's coursers and characteristics of the habitat around the strips, using ground-based survey data and satellite imagery. 4. Jerdon's coursers were most likely to occur where the density of large (>2 m tall) bushes was in the range 300-700 ha(-1) and where the density of smaller bushes was less than 1000 ha(-1). This habitat was detectable using satellite imagery. 5. Synthesis and applications. The occurrence of Jerdon's courser is strongly correlated with the density of bushes and trees, and is in turn affected by grazing with domestic livestock, woodcutting and mechanical clearance of bushes to create pasture, orchards and farmland. It is likely that there is an optimal level of grazing and woodcutting that would maintain or create suitable conditions for the species. Knowledge of the species' distribution is incomplete and there is considerable pressure from human use of apparently suitable habitats. Hence, distribution mapping is a high conservation priority. A two-step procedure is proposed, involving the use of ground surveys of bush density to calibrate satellite image-based mapping of potential habitat. These maps could then be used to select priority areas for Jerdon's courser surveys. The use of tracking strips to study habitat selection and distribution has potential in studies of other scarce and secretive species.

Putting the pieces back together again: an illustration of the problem of interpreting development indicators using an African case study

Indicators are commonly recommended as tools for assessing the attainment of development, and the current vogue is for aggregating a number of indicators together into a single index. It is claimed that such indices of development help facilitate maximum impact in policy terms by appealing to those who may not necessarily have technical expertise in data collection, analysis and interpretation. In order to help counter criticisms of over-simplification, those advocating such indices also suggest that the raw data be provided so as to allow disaggregation into component parts and hence facilitate a more subtle interpretation if a reader so desires. This paper examines the problems involved with interpreting indices of development by focusing on the United Nations Development Programmes (UNDP) Human Development Index (HDI) published each year in the Human Development Reports (HDRs). The HDI was intended to provide an alternative to the more economic based indices, such as GDP, commonly used within neo-liberal development agendas. The paper explores the use of the HDI as a gauge of human development by making comparisons between two major political and economic communities in Africa (ECOWAS and SADC). While the HDI did help highlight important changes in human development as expressed by the HDI over 10 years, it is concluded that the HDI and its components are difficult to interpret as methodologies have changed significantly and the 'averaging' nature of the HDI could hide information unless care is taken. The paper discusses the applicability of alternative models to the HDI such as the more neo-populist centred methods commonly advocated for indicators of sustainable development.

Late pleistocene ice export events into the Arctic Ocean from the M'Clure Strait Ice Stream, Canadian Arctic Archipelago

Rapidly-flowing sectors of an ice sheet (ice streams) can play ail important role in abrupt climate change through tile delivery of icebergs and meltwater and tile Subsequent disruption of ocean thermohaline circulation (e.g., the North Atlantic's Heinrich events). Recently, several cores have been raised from the Arctic Ocean which document the existence of massive ice export events during tile Late Pleistocene and whose provenance has been linked to Source regions in the Canadian Arctic Archipelago. In this paper, satellite imagery is used to map glacial geomorphology in the vicinity of Victoria Island, Banks Island and Prince of Wales Island (Canadian Arctic) in order to reconstruct ice flow patterns in the highly complex glacial landscape. A total of 88 discrete flow-sets are mapped and of these, 13 exhibit the characteristic geomorphology of palaeo-ice streams (i.e., parallel patterns of large, highly elongated mega-scale glacial lineations forming a convergent flow pattern with abrupt lateral margins). Previous studies by other workers and cross-cutting relationships indicate that the majority of these ice streams are relatively young and operated during or immediately prior to deglaciation. Our new mapping, however, documents a large (> 700 km long; 110 km wide) and relatively old ice stream imprint centred in M'Clintock Channel and converging into Viscount Melville Sound. A trough mouth fan located on the continental shelf Suggests that it extended along M'Clure Strait and was grounded at tile shelf edge. The location of the M'Clure Strait Ice Stream exactly matches the Source area of 4 (possibly 5) major ice export events recorded in core PS 1230 raised from Fram Strait, the major ice exit for the Arctic Ocean. These ice export events occur at similar to 12.9, similar to 15.6, similar to 22 and 29.8 ka (C-14 yr BP) and we argue that they record vigorous episodes of activity of the M'Clure Strait Ice Stream. The timing of these events is remarkably similar to the North Atlantic's Heinrich events and we take this as evidence that the M'Clure Strait Ice Stream was also activated around the same time. This may hold important implications for tile cause of the North Atlantic's Heinrich events and hints at tile possibility of a pall-ice sheet response. (c) 2005 Elsevier B.V. All rights reserved.

Geomorphological Map of Ribbed Moraines on the Dubawnt Lake Palaeo-Ice Stream Bed: A Signature of Ice Stream Shut-down?

The beds of active ice streams in Greenland and Antarctica are largely inaccessible, hindering a full understanding of the processes that initiate, sustain and inhibit fast ice flow in ice sheets. Detailed mapping of the glacial geomorphology of palaeo-ice stream tracks is, therefore, a valuable tool for exploring the basal processes that control their behaviour. In this paper we present a map that shows detailed glacial geomorphology from a part of the Dubawnt Lake Palaeo-Ice Stream bed on the north-western Canadian Shield (Northwest Territories), which operated at the end of the last glacial cycle. The map (centred on 63 degrees 55 '' 42'N, 102 degrees 29 '' 11'W, approximate scale 1:90,000) was compiled from digital Landsat Enhanced Thematic Mapper Plus satellite imagery and digital and hard-copy stereo-aerial photographs. The ice stream bed is dominated by parallel mega-scale glacial lineations (MGSL), whose lengths exceed several kilometres but the map also reveals that they have, in places, been superimposed with transverse ridges known as ribbed moraines. The ribbed moraines lie on top of the MSGL and appear to have segmented the individual lineaments. This indicates that formation of the ribbed moraines post-date the formation of the MSGL. The presence of ribbed moraine in the onset zone of another palaeo-ice stream has been linked to oscillations between cold and warm-based ice and/or a patchwork of cold-based areas which led to acceleration and deceleration of ice velocity. Our hypothesis is that the ribbed moraines on the Dubawnt Lake Ice Stream bed are a manifestation of the process that led to ice stream shut-down and may be associated with the process of basal freeze-on. The precise formation of ribbed moraines, however, remains open to debate and field observation of their structure will provide valuable data for formal testing of models of their formation.

Subglacial bedform evidence for a major palaeo-ice stream and its retreat phases in Amundsen Gulf, Canadian Arctic Archipelago

Ascertaining the location of palaeo-ice streams is crucial in order to produce accurate reconstructions of palaeo-ice sheets and examine interactions with the ocean-climate system. This paper reports evidence for a major ice stream in Amundsen Gulf, Canadian Arctic Archipelago. Mapping from satellite imagery (Landsat ETM+) and digital elevation models, including bathymetric data, is used to reconstruct flow-patterns on southwestern Victoria Island and the adjacent mainland (Nunavut and Northwest Territories). Several flow-sets indicative of ice streaming are found feeding into the marine trough and cross-cutting relationships between these flow-sets (and utilising previously published radiocarbon dates) reveal several phases of ice stream activity centred in Amundsen Gulf and Dolphin and Union Strait. A large erosional footprint on the continental shelf indicates that the ice stream (ca. 1000 km long and ca. 150 km wide) filled Amundsen Gulf, probably at the Last Glacial Maximum. Subsequent to this, the ice stream reorganised as the margin retreated back along the marine trough, eventually splitting into two separate low-gradient lobes in Prince Albert Sound and Dolphin and Union Strait. The location of this major ice stream holds important implications for ice sheet-ocean interactions and specifically, the development of Arctic Ocean ice shelves and the delivery of icebergs into the western Arctic Ocean during the late Pleistocene.
