Os Problemas Ambientais em Cabo Verde - Políticas e Medidas de Protecção Ambiental

A presente dissertação teve como finalidade analisar os Problemas Ambientais em Cabo Verde, com destaque para as políticas e medidas implementadas no período que decorre de 1975 a 2010. Para tal, centrou-se no confronto de resultados de estudos que permitiram uma comparação entre os Concelhos da Praia e de São Salvador do Mundo, localizados no sul e no centro da ilha de Santiago, respectivamente. Como ponto de partida, fez-se uma caracterização climática/ambiental do país, salientando a sua fragilidade ambiental através de uma estreita ligação entre as suas características naturais e o estado de ambiente para delinear a evolução das medidas políticas e jurídicas tomadas no sentido de combater ou minimizar os problemas existentes. Todo o trabalho empírico foi realizado nos concelhos acima referidos, com base nos inquéritos efectuados junto dos moradores, escolas, técnicos e políticos que lidam com a problemática ambiental nesses Concelhos. Posteriormente, foi possível analisar profundamente as principais causas da degradação ambiental nos dois Concelhos como a pobreza, a escassez de água, o saneamento básico, o aumento da população, o êxodo rural e as construções clandestinas, estabelecendo uma correlação entre estas e o desenvolvimento económico-social e a qualidade de vida dos seus habitantes. Finalmente, expôs-se o trabalho realizado e o que se perspectiva fazer para sua mitigação, privilegiando a vertente pedagógica, destacando a importância do envolvimento de grupos comunitários para prossecução de acções diversificadas de sensibilização, de programação e da formação em paralelo com o reforço de fiscalização para melhor aplicação de normas existentes.

Extracção de Areia na Praia de Calhetona (Ilha de Santiago, Cabo Verde) - Causas, Processos e Consequências

A extracção de areia nas praias do mar, nas bacias hidrográficas e nas encostas montanhosas, tem sido prática de muitas famílias cabo-verdianas. A Praia de Calhetona foi uma das que nos últimos anos sofreu degradação significativa, em função da apanha clandestina de areia, sem qualquer plano de extracção, destinada a construção civil. A extracção de areia, para vender ou para a autoconstrução, é efectuada em família por indivíduos, maioritariamente do sexo feminino, de baixa renda ou sem profissão remunerada. O processo de extracção de areia na Praia de Calhetona teve o seu ponto alto nos anos 80, diminuindo consideravelmente com a escassez de areia e implementação do Decreto – Lei nº 69/97, de 3 de Novembro, que visava disciplinar a exploração de inertes nas praias. Em face da pesquisa feita, baseada no estudo de caso, ficou expresso que os inquiridos implicados na actividade de extracção clandestina de areia correm riscos elevados para obterem lucros reduzidos. Quem efectivamente beneficia são os camionistas que compram esse inerte e o vendem pelo dobro do preço. Qualquer actividade de exploração de recursos naturais causa impactes sobre o espaço de actuação. No caso da Praia de Calhetona, observa-se o recuo da linha de costa, a quase ausência de areia e a desertificação de propriedades nas suas proximidades, para além dos impactes negativos sobre o turismo, a função balnear e a desova de tartaruga. Apesar de tudo, constata-se uma consciência generalizada dos impactes ambientais causados pelos inquiridos, os quais, no entanto, alegam que a extracção de areia é uma das alternativas para garantir a sobrevivência individual e das suas famílias.

Organized vs. competitive corruption

We study bureaucratic corruption in a model in which a constituencysets required levels for a given set of activities. Each activity iscarried out by an external provider, and its realization is supervisedby a bureaucrat. While bureaucrats are supposed to act on behalf of theconstituency, they can decide to be corrupt and allow providers todeliver lower activity levels than contracted in exchange for a bribe.Given this, the constituency sets the optimal activity levels weighingoff the value of activity levels, their costs, as well as the possibilityfor the bureaucrats to be corrupt. We use this setup to study the impacton equilibrium corruption of the degree of decentralization of corruption.To do this we compute equilibrium corruption in two different settings:1) Each bureaucrat acts in such a way as to maximize his own individualutility (competitive corruption); 2) An illegal syndicate oversee thecorruption decisions of the population of bureaucrats in such a way asto maximize total proceeds from corruption (organized corruption). Weshow that, since average corruption payoff is increasing in the activitylevels set by the constituency, and since the latter responds to highlevels of corruption by reducing required activity levels, in equilibriumthe illegal syndicate acts in such a way as to restrain the total numberof corrupt transactions, so that corruption is lower when it is organizedthan when it is competitive.

Critical Role of the GM-CSF Signaling Pathway in Macrophage Pro-Repair Activities.

OBJECTIVE: Macrophages play a critical role in intestinal wound repair. However, the molecular pathways that regulate macrophage wound repair activities remain poorly understood. The aim of this study was to evaluate the role of GM-CSF receptor signaling in the wound repair activities of macrophages. METHODS: Murine macrophages were differentiated from bone marrow cells and human macrophages from monocytes isolated from peripheral blood mononuclear cells of Crohn's disease (CD) patients. In vitro models were used to study the repair activities of macrophages. RESULTS: We provide evidence that GM-CSF receptor signaling is required for murine macrophages to promote epithelial repair. In addition, we demonstrate that the deficient repair properties of macrophages from CD patients with active disease can be recovered via GM-CSF therapy. CONCLUSION: Our data support a critical role of the GM-CSF signaling pathway in the pro-repair activities of mouse and human macrophages. © 2014 S. Karger AG, Basel.

Tax Credit Evaluation Study: Research Activities Tax Credit, January 2008

During the 2005 Legislative Session the Iowa Department of Revenue received an appropriation to establish the Tax Credits Tracking and Analysis Program (TCTAP) to track tax credit awards and claims. In addition, the Department was directed to perform periodic evaluations of tax credit programs. The purpose of these studies is three-fold: (1) To provide a comparison of the Iowa tax credit program to similar federal and other states’ programs (2) To summarize information related to the usage of the Iowa tax credit (3) To evaluate the economic impact of the tax credit program.

Grundriss innovativer Polizeiansätze. Eine kritische Begutachtung verschiedener Strategien und Tätigkeiten und deren Implementierung in der Schweiz in Theorie und Praxis.

This thesis contains three parts. The first one offers the theoretical basement, where the history of the police from their beginning in the early 19th century to this day is shown. The emphasis however is laid on the last 40 years, which gave birth to a multitude of innovations, such as community, problem-oriented, hot-spots or zero-tolerance policing. Those innovations are described in detail and are critically commented. At the end of this section, I present a scheme, where all the approaches are classified as strategic or methodic innovations, but united under a model called "modern policing". The fact that the innovations are not competitive but rather complementary is the most important finding of this examination. The second part of this work deals with a unique survey about the implementation of four innovations and eight problem- and community-oriented activities in 85 Swiss police forces. This explorative study shows that in the last 15 years the Swiss police forces have increasingly adopted innovative approaches. The most frequent innovation is community policing, which has been implemented all over the country. Due to the results, we can also assume that the implementation of the innovations is mostly substantial and profound. However, particularly in the area of problem-solving there is still a need for improvements. The third section consists of a scientific evaluation of a temporary special unit of the municipal police Zurich, which, during nine months, fought against public drug dealing and illegal prostitution in a particular neighborhood called Langstrasse. The effects of this hot-spot project were measured with police data, observations and several population surveys. In general, the special unit achieved a positive outcome and helped to defuse the hot-spot. Additionally, a survey conducted within the police department showed that the personal attitude towards the special unit differed widely between the policemen. We found significant differences between both police regions East and West, rank-and-file and higher ranking officers, different ages and the personal connection to the special unit. In fact, the higher the rank, the lower the age, and the closer the relationship, the more positive the officers were towards the unit.

Differences in diet between the two largest breeding colonies of Audouin's gulls: the effects of fishery activities

We analysed and compared the diet of Audouin´s gulls Larus audouinii between their two largest breeding sites in the world: the Ebro Delta and the Chafarinas Islands (western Mediterranean). These two localities showed marked differences in the features of the commercial fishing fleet: in the Ebro Delta area a large fishing fleet produced large amounts of discards, while in the Chafarinas the fleet discarded smaller amounts of fish and marine invertebrates, due to the smaller number of vessels. It is also likely that the percentage of discards from total catches is also lower around the Chafarinas than at the Ebro Delta. We distinguished two types of fishing to compare diet compositions: diurnal (only trawling activity) and diurnal and nocturnal (trawling and purse-seine activity, respectively). We also differentiated regurgitates from young nestlings (up to 20 days old) and from older nestlings or adult birds. At the two localities, fish was the main food of Audouin´s gulls, with epipelagic prey (mainly clupeoids) being more important when both diurnal and nocturnal fisheries were operating. This confirms that epipelagic prey either caught actively by the gulls or linked to fisheries was particularly important in the feeding habits of Audouin´s gulls. Nevertheless, differences between the two colonies appear mainly when only trawlers operated: while at the Ebro Delta gulls showed higher consumption of benthic-mesopelagic prey (probably linked to a higher trawler discard availability), gulls from the Chafarinas Islands consumed higher biomass of epipelagic prey probably caught actively at night. When both fleets operated around the two colonies, the average biomass of prey in a regurgitate of younger chicks was significantly higher at the Ebro Delta than at Chafarinas, and the opposite trend was recorded for older nestlings and adults. Niche width was broader in Chafarinas than in the Ebro Delta for both age classes and for any fishing fleet schedule, suggesting again that the exploitation of discards was higher at the Ebro Delta than at the Chafarinas, where gulls showed a more varied diet. Despite the fact that availability of discards was probably higher at the Ebro Delta than at Chafarinas, the per capita availability was not so different at both localities due to the increasing seabird community population at the Ebro Delta, which ca. doubled that at Chafarinas in the last decade.

Secular trends in legal and illegal substance use among 16 to 20 year old adolescents in Switzerland.

BACKGROUND: Data targeting trends in legal and illegal substance use by adolescents are scarce. Using the data from two similar large national surveys run in 1993 and 2002, this paper assesses secular trends in rates of substance use among 16-20-year-old Swiss adolescents. METHODS: Self-reported regular use of tobacco, alcohol misuse, regular cannabis use (01 occasion over last 30 days) and lifetime use of psychoactive medication, LSD, ecstasy, cocaine and heroine were assessed through identical questions using an anonymous self-administered questionnaire. 9268 (1993) and 7428 (2002) high school students and apprentices were included in the analyses. RESULTS: There is a higher proportion of regular smokers among apprentices than among students (p <0.001). Between 1993 and 2002 the increase in regular tobacco consumption was significant among both female and male apprentices (p <0.001) but not among students. Between 1993 and 2002 alcohol misuse significantly increased in all four groups (p <0.001). It is more prevalent among males than among females (p <0.001) and higher among apprentices than among students (p <0.001). Regular use of cannabis has increased in the four groups (p <0.0001). It is higher among males than among females (p <0.001), while it is largely the same among students and apprentices. While the increase in ecstasy use is highly significant in all four groups (p <0.001), the increase in LSD and cocaine use is significant among apprentices only (p <0.001). Use of LSD, ecstasy and cocaine is more prevalent among males than among females (<0.001) and higher among apprentices than among students (p <0.001). CONCLUSION: The secular increase in psychoactive substance use among older Swiss adolescents calls for the implementation of effective strategies both from individual and public health viewpoints.
