Os fluxos gerados pela economia de Cabo Verde, desde sempre, foram insuficientes para financiar o seu desenvolvimento, devido aos constrangimentos relativas à falta de recursos naturais, ao défice da balança comercial e à dimensão e fragmentação do território. Neste sentido, o capital estrangeiro surge como um recurso estratégico no desenvolvimento de CV, sendo um instrumento chave para colmatar alguns défices da economia cabo-verdiana. Logo a relevância do estudo proposto, que parte da questão: “Os incentivos e o ambiente oferecidos por CV têm sido suficientemente eficientes para atrair o IDE ou os números poderiam estar melhores?” Na sequência da revisão teórica e da literatura, a fim de obter a resposta à pergunta da pesquisa, analisamos os incentivos e o ambiente oferecidos aos investidores externos, através de instrumentos empreendidos pelo Governo de CV e analisamos a evolução dos fluxos do IDE no país, com especial atenção ao período 2000-2006, a partir de dados estatísticos. A análise posterior – percepção dos investidores externos em CV – deu lugar a um estudo qualitativo, a partir de um inquérito efectuado à uma amostragem probabilística de dez investidores externos, elegidos a partir de critérios fundamentados. Como resultado, observamos que os instrumentos empreendidos pelo Governo na atracção do IDE têm mais de dez anos de existência, não coincidindo com os maiores picos de IDE em CV ocorridos nos dois últimos anos. Observamos, ainda, que, de uma forma geral, os investidores externos privilegiam o mercado cabo-verdiano pela estabilidade política e económica. Por outro lado, apontam grandes constrangimentos a nível de infra-estrutura, ligações marítimas internas e aéreo para o exterior. As formalidades administrativas foram, também, objecto de avaliação negativa por parte dos investidores inquiridos. Posto isto, concluímos que, de uma forma geral, os instrumentos de atracção ao IDE em CV não são suficientemente eficazes para atender às necessidades dos investidores externos. Isto demonstra que há um interessante terreno a ser explorado. The cash flows generated Cape Verde’s economy, so far, have been insufficient to finance its development, due to constraints concerning the lack of natural resources, the trade balance deficit and the geographical distribution and dimension of the territory. In this context, foreign capital appears as a strategic resource for Cape Verde’s development. Foreign investment is a significant instrument to overcome some shortfalls of the cape-verdean economy. Therefore the relevance of this study which is based on the question: "The incentives offered by CV and the environment have been effective enough to attract FDI or the numbers could be better?" Following the literature and theoretical review, in order to get the answer to the research question, we have analyzed the stimulus and environment provided to foreign investors through instruments launched by the Government. We have analysed the evolution of FDI´s flows into the country, with particular focus on the period 2000 - 2006, from statistical data. The subsequent analysis - the perception of foreign investors in CV - produced a qualitative survey study, conduced on a sampling of ten foreign investors, selected from founded criterions. As a result, we observed that the instruments undertaken by the Government in attracting FDI are over than ten years old and the higher FDI peak took place during the two last years. It was noticed that foreign investors choose the cape-verdean market because of its politic and economic stability. On the other hand, foreign investors show great constraints in terms of infrastructure, internal maritime connection and international flight connections. The administrative formalities are also subject of a negative evaluation by the investors surveyed. We have eventually figured out that the attraction instruments for FDI in CV are not effective enough for the needs of foreign investors. This demonstrates that there is a interesting ground to be explored.

A Comparison of the Management Models of Protected Areas between China and the African South Region allows reading and evaluating the similarities and differences in the use of management model as a management tool for protected areas in China and South African Region. Specifically, some positive and negative features of the management approaches for the two regions. Secondary data was collected from various related literature such as policy documents, students‟ dissertations/thesis, scientific articles and magazines. Based on the method above, the study found out that China's first nature reserve was the Dingus Mountain Nature Reserve in Zhaoqing, Guangdong province established in 1956. By the end of 2005, about 2,349 nature reserves of various kinds were set up throughout the country, covering a total area of 149.95 million ha and accounting for 15 percent of the total land territory. The study further found that Southern Africa has approximately 4,390 protected areas out of 11487920 total land areas and Eastern Africa has approximately 1838144 protected areas, which is equivalent to 15.0% of the total land areas. South Africa in this region had its first declared natural park in 1926 after Paul Kruger (a war hero) had alerted the authorities of the extinguishing threat of some animal species of region.

The problem of small Island Developing States (SIDS) is quite recent, end of the 80s and 90s, still looking for a theoretical consolidation. SIDS, as small states in development, formed by one or several islands geographically dispersed, present reduced population, market, territory, natural resources, including drinkable water, and, in great number of the cases, low level of economic activity, factors that together, hinder the gathering of scale economies. To these diseconomies they come to join the more elevated costs in transports and communications which, allies to lower productivities, to a smaller quality and diversification of its productions, which difficult its integration in the world economy. In some SIDS these factors are not dissociating of the few investments in infrastructures, in the formation of human resources and in productive investments, just as it happens in most of the developing countries. In ecological terms, many of them with shortage of natural resources, but integrating important ecosystems in national and world terms, but with great fragility relatively to the pollution action, of excessive fishing, of uncontrolled development of tourism, factors that, conjugated and associated to the stove effect, condition the climate and the slope of the medium level of the sea water and therefore could put in cause the own survival of some of them. The drive to the awareness of the international community towards its problems summed up with the accomplishment by the United Nations in the Barbados’s Conference, 1994 where the right to the development was emphasized, through the going up the appropriate strategies and the Programme of Action for the Sustainable Development of the SIDS. The orientation of the regional and international cooperation in that sense, sharing technology (namely clean technology and control and administration environmental technology), information and creation of capacity-building, supplying means, including financial resources, creating non discriminatory and just trade rules, it would drive to the establishment of a world system economically more equal, in which the production, the consumption, the pollution levels, the demographic politics were guided towards the sustainability. It constituted an important step for the recognition for the international community on the specificities of those states and it allowed the definition of a group of norms and politics to implement at the national, regional and international level and it was important that they continued in the sense of the sustainable development. But this Conference had in its origin previous summits: the Summit of Rio de Janeiro about Environment and Development, accomplished in 1992, which left an important document - the Agenda 21, in the Conference of Stockholm at 1972 and even in the Conference of Ramsar, 1971 about “Wetlands.” CENTRO DE ESTUDOS AFRICANOS Occasional Papers © CEA - Centro de Estudos Africanos 4 Later, the Valletta Declaration, Malta, 1998, the Forum of Small States, 2002, get the international community's attention for the problems of SIDS again, in the sense that they act to increase its resilience. If the definition of “vulnerability” was the inability of the countries to resist economical, ecological and socially to the external shocks and “resilience” as the potential for them to absorb and minimize the impact of those shocks, presenting a structure that allows them to be little affected by them, a part of the available studies, dated of the 90s, indicate that the SIDS are more vulnerable than the other developing countries. The vulnerability of SIDS results from the fact the they present an assemblage of characteristics that turns them less capable of resisting or they advance strategies that allow a larger resilience to the external shocks, either anthropogenic (economical, financial, environmental) or even natural, connected with the vicissitudes of the nature. If these vulnerability factors were grouped with the expansion of the economic capitalist system at world level, the economic and financial globalisation, the incessant search of growing profits on the part of the multinational enterprises, the technological accelerated evolution drives to a situation of disfavour of the more poor. The creation of the resilience to the external shocks, to the process of globalisation, demands from SIDS and of many other developing countries the endogen definition of strategies and solid but flexible programs of integrated development. These must be assumed by the instituted power, but also by the other stakeholders, including companies and organizations of the civil society and for the population in general. But that demands strong investment in the formation of human resources, in infrastructures, in investigation centres; it demands the creation capacity not only to produce, but also to produce differently and do international marketing. It demands institutional capacity. Cape Verde is on its way to this stage.

Objective To associate the territory of identity with the production of care within a PCC focusing on children and adolescents with drug abuse and their institutional identity. Method We used the “ process tracing methodology” in four research categories: focus groups, characterization of professionals, observing the everyday and interviewing two members of emblematic cases of the service. Results territory of identity of the institution, which operates the production of care is crossed by the difficulty of dealing with the complexity brought by the users and the performance of the PCC network. This paper is also permeated by different conceptions of care and small problematization of these issues in collective spaces of service. Conclusion The discussion in focus groups and other devices can be powerful resources to reframe the meaning of care and identity of collective service.

Ectoparasites are common in most bird species, but experimental evidence of their effects on life-history traits is scarce. We investigated experimentally the effects of the hematophagous hen flea (Ceratophyllus gallinae) on timing of reproduction, nest-site choice, nest desertion, clutch size, and hatching success in the great tit (Parus major). When great tits were offered a choice on their territory between an infested and a parasite-free nest-box, they chose the one without parasites. When there was no choice, the great tits in a territory containing an infested nest-box delayed laying the clutch by 11 days as compared with the birds that were offered a parasite-free nesting opportunity. The finding that there was no difference in phenotypic traits related to dominance between the birds nesting in infested boxes and birds nesting in parasite-free boxes suggests that the delay is not imposed by social dominance. Nest desertion between laying and shortly after hatching was significandy higher in infested nests. There was no difference between infested and parasite-free nests in clutch size, but hatching success and hence brood size at hatching were significantly smaller in infested nests. Nest-box studies of great tits have been seminal in the development of evolutionary, ecological, and behavioral theory, but recently a polemic has arisen in the literature about the validity of the conclusions drawn from nest-box studies where the naturally occurring, detrimental ectoparasites are eliminated by the routine removal of old nests between breeding seasons. Our study suggests that this criticism is valid and that the evaluation of the effects of ectoparasites may improve our understanding of behavioral traits, life-history traits, or population dynamics

Thermal requirements of Aedes (Stegomyia) albopictus Skuse, 1894 (Diptera, Culicidae) under laboratory conditions. Allochtonous species of Ae. albopictus in the American continent can be found in fourteen Brazilian states - about fifteen years had been elapsed since the first report of the presence of this species in Brazilian territory. Considering its potential epidemiological importance and its adaptation to several habitats, it was determined, for this species, the threshold temperature and the thermal constant for egg, larval and pupal stages under laboratory conditions under four constant temperatures and 12:12 hours light-dark photoperiod. The threshold temperature for the egg phase and for the first instar were quite similar: 9.07 ºC (K=214.46 degree days) and 9.23 ºC (K= 36.64 degree days), respectively. For 2nd, 3rd and 4th instar, the basal-temperature was higher, oscilating between 12.26 ºC and 13.95 ºC. The threshold temperature for the complete larval stage and for the pupal stage were 12.03 ºC (K= 99.48 degree days) and 11.87 ºC (K=32.40 degree days) for males and 11.95 ºC (K=110.11 degree days) and 11.60 ºC (K=35.30 degree days) for females, respectively.

Cabo Verde desde do século passado tem envidado esforço na florestação, sobretudo depois de 1975 para atenuar os efeitos da seca e da desertificação criando deste modo grandes áreas arborizadas. Entretanto, à medida que os recursos florestais foram sendo criados, a problemática da sua avaliação e da sua gestão sustentável, passaram a merecer maior atenção das autoridades nacionais. A lei florestal, promulgada em 1998 define como uma das atribuições e acções do Estado, através dos serviços florestais, a elaboração dos planos de gestão das zonas florestais. Este plano de gestão implica a análise e a apreciação de dados concretos e actualizados sobre a situação real das zonas florestais, sendo possível apenas através do inventário florestal nacional (IFN). Neste trabalho é proposta uma metodologia de processamento do IFN em que se utilizam as potencialidades dos Sistemas de Informação Geográfica (SIG). Foram utilizados para este trabalho os programas: ArcGis 9.1, para produção cartográfica, geoprocessamento e análise espacial e o Field-Map 8.1 para a classificação de ortofotos num esquema de classificação hierárquica, em cinco níveis, adaptado a Cabo Verde (classes de uso do solo adoptado ao esquema de classificação do território europeu – CORINE Land Cover e da Organização das Nações Unidas para a Agricultura e Alimentação (FAO). Os dados utilizados foram compilados no âmbito do projecto do inventário florestal. Os resultados obtidos, para a Ilha de Santiago, constituem uma base cartográfica para o IFN com diversos temas cartográficos, nomeadamente, mapas das zonas florestadas, mapas de ocupação do solo e mapas de amostras inventariáveis cuja metodologia de elaboração poderá ser facilmente replicada para as restantes ilhas do arquipélago.

We performed a systematic review of the literature to establish whether revascularisation of the left subclavian territory is necessary when this artery is covered by a stent. We retrieved data from 99 studies incorporating 4906 patients. Incidences of left-arm ischaemia (0.0% vs 9.2%, p=0.002) and stroke (4.7% vs 7.2%, p<0.001) were significantly less following revascularisation, although mortality (10.5% vs 3.4%, p=0.032) and endoleak incidence (25.8% vs 12.6%, p=0.008) were increased. No significant differences in spinal-cord ischaemia were seen. Revascularisation may reduce downstream ischaemic complications but can cause significant risk. Indications must be carefully considered on an individual patient basis.

Protomeliturga turnerae (Ducke, 1907) represents the monotypic tribe Protomeliturgini (Andrenidae, Panurginae). The species is oligolectic on flowers of Turnera L. (Turneraceae). A survey of bees on flowers of Turneraceae and of material in entomological collections showed that P. turnerae is common and endemic in Northeastern Brazil, occurring from the State of Maranhão to Alagoas. In João Pessoa, Paraíba, we studied the reproductive biology and mating behavior of P. turnerae and its relations to plants. At the study site, the species was univoltine with males emerging 5-8 days before the females. Soon after emergence the males established territories on flowers of Turnera subulata Smith which they occupied during several days. Parts of each territory overlapped with those of 1 to 3 other males. On the average, a territory comprised 124 flowers, 59 being shared with other males. Males showed two mating strategies: patrolling the flowers of T. subulata in which females collected pollen or waiting in a specific flower inside the territory for arriving females. P. turnerae showed multiple mating. On the average, a male mated 7 times a day, each copula lasting 3 to 25 sec. We observed 2 to 3 males attempting to copulate with the same female. At the end of anthesis of T. subulata the males stopped flying activity and remained inside flowers until their closure.

Using a rich dataset of territories and cities of the Holy Roman Empire in the16th century, this paper investigates the determinants of adoption and diffusion ofProtestantism as a state religion. A territory s distance to Wittenberg, the city whereMartin Luther taught, is a major determinant of adoption. This finding can be explainedthrough a theory of strategic neighbourhood interactions: in an uncertainlegal context, introducing the Reformation was a risky enterprise for territorial lords,and had higher prospects of success if powerful neighbouring states committed tothe new faith first. The model is tested in a panel dataset featuring the dates ofintroduction of the Reformation.

Rockfall hazard zoning is usually achieved using a qualitative estimate of hazard, and not an absolute scale. In Switzerland, danger maps, which correspond to a hazard zoning depending on the intensity of the considered phenomenon (e.g. kinetic energy for rockfalls), are replacing hazard maps. Basically, the danger grows with the mean frequency and with the intensity of the rockfall. This principle based on intensity thresholds may also be applied to other intensity threshold values than those used in Switzerland for rockfall hazard zoning method, i.e. danger mapping. In this paper, we explore the effect of slope geometry and rockfall frequency on the rockfall hazard zoning. First, the transition from 2D zoning to 3D zoning based on rockfall trajectory simulation is examined; then, its dependency on slope geometry is emphasized. The spatial extent of hazard zones is examined, showing that limits may vary widely depending on the rockfall frequency. This approach is especially dedicated to highly populated regions, because the hazard zoning has to be very fine in order to delineate the greatest possible territory containing acceptable risks.

Searching for a suitable breeding site is an important decision in the life of most animals. The decisions where to settle and how far to travel before doing so depend on many factors. Individual differences in dispersal distance could result from different strategies (e.g. specialists versus generalists), which might result in similar reproductive success in different habitats, or different competitive abilities to acquire a territory close to the natal site. The barn owl is polymorphic in melanic coloration, which is associated with many physiological and behavioural traits such as habitat choice, stress response and docility, raising the possibility that the coloration is also related to dispersal. We studied natal dispersal (from rearing site to site of first breeding attempt) and breeding dispersal (from one breeding site to the next) in barn owls using a long-term data set. Darker reddish individuals moved further than paler individuals during natal dispersal, but not during breeding dispersal. A cross-fostering experiment showed that the colour of the biological and foster parents had no influence on dispersal distance. The distance dispersed by parents and same-sex offspring was correlated, whereas natal and breeding dispersal were not repeatable within individuals, indicating that they are two different processes. Given that the distance travelled in natal dispersal appears to be heritable, the underlying genes might be coupled to those related to coloration. We discuss hypotheses to explain the potential adaptive function of the link between coloration and natal dispersal.

This work contributes to an understanding of how the existence of multiple ethnic- cultural belongings in the political community concurs with the maintenance of a socially cohesive and politically united community. Considering the immigration reality in Portugal, we tried to identify the bonds that link immigrants to the political community and how those bonds can be mobilized to integrate immigrants in a common living project inside the national territory. Methodologically, this investigation is based in a qualitative and quantitative analysis of the policies and measures applied in Portugal in the immigration sphere, as well as the results of the empirical work we carried out with two immigration groups (Brazilians and Cape Verdeans) living in Lisbon’s metropolitan area, and the answers to a survey we sent to immigrant associations. The results of this research revealed the existence of a certain political ambivalence concerning the immigrant integration process, which expresses itself to a certain degree in the way national citizens and immigrants appraise the immigrant contribution to Portuguese society. The prevailing and blurred idea states that immigration expenses don’t make up for the benefits, and that is likely to influence the mutual relationship established between the two. Despite the existence of objective situations of social and economic disparity and despite a feeling of discrimination shared between immigrants, it is possible to identify a progressive citizenship universalization and the formal acceptance of immigrant religious and cultural traditions, even though the Portuguese parliament does not reflect such diversity. Thus, we perceive the possibility of warranting specific ethnic and cultural minority rights without the ethnicization or culturalization of political representation, and the general standards that serve as a backbone to the national political community might be enough to warrant that protection. Notwithstanding, some signs suggest that immigrant access to public sphere might not be easy, and this might have repercussions in the visibility and in the public discussion of demands, with outcomes on the type of integration policies Portugal applies.

A identificação de dois recipientes colocados ritualmente em posição invertida, conotáveis com a derradeira fase de ocupação do povoado calcolítico do Outeiro Redondo (Sesimbra), e deste modo com uma cerimónia de abandono do próprio sítio arqueológico, conduziu à procura de exemplos comparáveis. Tal procura estendeu‑se, depois, às evidências de utilização ritual, em contextos habitacionais, de recipientes cerâmicos, desde a época a que pertencem os exemplares em causa, até ao Período Romano. Teve‑se ainda em consideração o contributo da Etnografia e da Arqueologia africana, através da experiência do signatário, relacionada com intervenção arqueológica que dirigiu em unidade doméstica do século XVII/XVIII da ilha de São Vicente (República de Cabo Verde). Sem se pretender assumir a continuidade desta prática ritual no actual território português, desde o Calcolítico até pelo menos à Época Romana, por poder tratar‑se de uma simples convergência, recorrentemente verificada ao longo da Idade do Bronze e do Ferro. Como se deverá interpretar o achado do Outeiro Redondo? As evidências assinaladas através do uso ritual de recipientes cerâmicos em contextos habitacionais podem ter um significado ligado ao próprio quotidiano, como no povoado de Fraga da Pena (Fornos de Algodres). Aquelas afiguram‑se, contudo, mais abundantes e expressivas no que se refere quer às práticas de natureza fundacional, quer às relacionadas com o abandono; por vezes, dada a presença de aves sacrificadas, tais rituais poderiam também revestir uma função propiciatória, que não é incompatível com as duas funções mencionadas, também elas não incompatíveis entre si.

O trabalho que agora se apresenta é fruto, antes de mais, de uma relação especial com Timor. Não necessariamente pela dimensão histórica das várias presenças naquele território mas, e acima de tudo, pela relação pessoal e afectiva com alguns dos responsáveis políticos e religiosos daquele jovem país. Um convite, formulado em 2007 por Xanana Gusmão, levou-nos a calcorrear todo o território num curto espaço de três semanas, corria o Verão de 2008. O objectivo era a análise, no terreno, da viabilidade da instalação de um poder local num país recentemente tornado independente. Timor, fruto da sua história e, muito em especial, das características antropológicas do seu povo, é uma nação assumidamente multicultural. Das origens ancestrais das suas comunidades, dos reinos dispersos que pulverizam o pequeno território, das suas lideranças e dos vários dilectos, associados à longa e marcante presença portuguesa, bem como outras ocupações de países estrangeiros, com destaque para a Indonésia, resulta um caldo cultural, a todos os níveis peculiar. Aqui e acolá ouvimos o povo, entrevistámos e reunimos com os 432 chefes de suco existentes no país, entrevistámos chefes de aldeia e anciãos, reunimos com políticos, sacerdotes, professores e jornalistas. Interpretámos, ou tentámos interpretar, as condicionantes e os cuidados que se devem observar na preparação do quadro jurídico para reger a municipalidade em Timor: as suas vertentes electivas, funcionais, financeiras e fiscalizadoras. Revistámos a História de Timor e passámos por Cabo Verde, país de referência internacional ao nível da sua gestão pública, muito em especial a autárquica. Fizemos, também, óbvia referência à história do poder local em Portugal. Das consultas, do muito que observámos e estudámos, resulta um desinteressado contributo para a implementação do poder local em Timor, com as conclusões que incorporam alertas e sugestões.
