A marginalização do Vale do Cávado e do Ave

Marginalizar o Cávado e o Ave é marginalizar o próprio Porto dentro de si e, portanto, todo o Norte. Assim como em Lisboa, há quem de dentro do Porto, ainda não entenda bem o que é o Vale do Cávado e do Ave!; Abstract: marginalize the Cávado and Ave is to marginalize the very Oporto within itself and therefore the entire North. As in Lisbon, some from within the Oporto, still do not understand well what is the Valley of Cávado and Ave!

As autarquias e a educação. Centro e periferia na construção das políticas educativas (1998-2008)

RESUMO: Com o actual quadro de descentralização de atribuições e competências da administração central para as autarquias locais, na área da educação, os municípios passam a investir cada vez mais na acção educativa ao liderarem e planearem políticas educativas locais mais ou menos explícitas, e, nalguns casos, tentando superar carências que o sistema educativo apresenta. Esta pesquisa tem como problemática compreender o papel do Estado na (re)configuração das políticas de educação, quando a tendência para a mudança, de um Estado-educador para um Estado-regulador, tem por pressuposto o discurso neoliberal de que com ‗menos‘ Estado mas maior accountability se obtêm melhores resultados. Este processo origina uma redefinição no papel e funções do Estado no plano social e económico, provocando constrangimentos e conflitos de poder no que respeita ao seu controlo político, com a redistribuição de poderes entre o Estado e a comunidade, entre o central e o local. É neste contexto de mudança que a presente investigação, que se situa no âmbito da análise das políticas educativas, procura averiguar como e com que meios as autarquias locais concretizam as suas competências na área da educação. A estratégia de investigação concentra-se em uma metodologia qualitativa, com a utilização de um estudo exploratório, em três municípios da Região de Lisboa e Vale do Tejo. As actuais políticas educativas derivam da nova visão na gestão da coisa pública – res publica –, como resultado da nova concepção para o próprio Estado, e dos processos de elaboração das decisões político-educativas. Nesta perspectiva, a descentralização passa a ser um instrumento do poder local que favorece o aumento da autoridade democrática dos actores. Todavia, a governação – governance – supõe uma dinâmica de negociação, até mesmo de regulação entre o Estado, a região, o local, a escola e o mercado, feita para atender à construção do interesse geral, que já não é totalmente definido pelo Estado, mas construído em conjunto com as diversas forças políticas, económicas, educativas e sociais. O estudo permitiu evidenciar que a descentralização é posta em causa pelo Estado central, quando este ‗recentraliza‘ decisões e condiciona o poder local, com o fecho da maioria das escolas do primeiro ciclo e a verticalização dos agrupamentos escolares. Por sua vez, algumas políticas educativas como a ‗Escola a Tempo Inteiro‘ fomentam a desregulação dos vínculos laborais, forçando os municípios a aumentar os seus meios técnicos e humanos e a construírem novas infra-estruturas educativas. As políticas educativas passaram a ser concebidas segundo uma matriz híbrida, que visam a municipalização da educação – do pré-escolar e de todo o ensino básico –, por um lado; e fomentam a situação de ‗quase-mercado‘ com a privatização de sectores e o financiamento de várias instituições – que fornecem serviços na área da educação –, por outro lado. ABSTRACT: With the current framework of decentralization of functions and powers from central government to local authorities, in education, the municipalities are investing each more in educational work in leading educational policies and planning places more or less explicit and in some cases, trying to overcome shortcomings that education system. This research aims to understand the role of the state in the (re) configuration of education policies, when the tendency for the change in a State-Educator for a State-regulator, is the assumption that neo-liberal speech that with 'less' State but with more accountability we achieve better results. This process leads to a redefinition of the role and State functions in socio-economic constraints, resulting in power struggles with regard to its political control, with the redistribution of powers between the state and community, between the central and local. It is in this changing context that the present investigation, which lies in the examination of education policy addresses the question how and by what means the local, materialized their skills in education. The strategy focuses on a qualitative methodology, with the use of an exploratory study in three municipalities of Lisbon and Tagus Valley. The current education policies come from the new vision in the management of public affairs - res publica - as a result of the new design for the State itself, and the process of preparation of educational policy decisions. In this perspective, decentralization becomes an instrument of local government that favours the increase of democratic authority of the actors. However, the governance assumes a dynamic negotiation, even in regulation between the State, region, local authorities, school and market, made to suit the construction of general interest, which is not anymore fully defined by the State, but constructed together with the various political, economic, educational and social forces. The study indicates that decentralization is undermined by the central government when it ‗re-centralize‘ decisions and the local conditions, with the closure of most primary schools and with vertical groupings of schools. In turn, some educational policies such as 'Full Time School' forced the municipalities to increase their technical and human resources, to build new educational infrastructure. The educative policies began to be designed according to a hybrid matrix, which aims the decentralization of education - from pre-school and all the primary school - on one hand, and promote the situation of 'quasi-market' with privatization of sectors and the financing of several institutions - that provide services in education -, on the other hand. RÉSUMÉ: Avec le cadre actuel de décentralisation des fonctions et pouvoirs du gouvernement central aux autorités locales, dans l'éducation, les municipalités investissent de plus en plus dans le travail éducatif dans la conduite des politiques éducatives en mener et en faisant la planification des lieux plus ou moins explicites et, dans certains cas, essayer de remédier aux lacunes que présente l'éducation. Donc, nous voulons avec cette recherche comprendre le rôle de l'Etat dans la (re) configuration des politiques d'éducation, alors que la tendance au changement d‘un État-éducateur pour un État-régulateur, a comme l'hypothèse le discours néo-libéral de que avec «moins» État, mais plus d‘accountability on a des meilleurs résultats. Ce processus conduit à une redéfinition du rôle et des fonctions de l'Etat au plan social et économique, en donnant lieu à des luttes de pouvoir à l'égard de son contrôle politique, avec la redistribution des compétences entre l'État et la collectivité, entre les niveaux central et local. C‘est dans ce contexte changeant que la présente enquête, qui réside dans l‘examen de la politique de l‘éducation aborde la question de savoir comment et par quels moyens le local matérialisé leurs compétences dans l‘éducation. La stratégie est axée sur une méthodologie qualitative, avec l'utilisation d'une étude exploratoire dans trois municipalités de Lisbonne et Vallée du Tage. Les politiques actuelles d'éducation sont tirées de la nouvelle vision dans la gestion des affaires publiques - res publica – à la suite de la nouvelle conception de l'État lui-même, et le processus de préparation des décisions politique-éducatives. Dans cette perspective, la décentralisation devient un instrument de gouvernement local qui favorise l'augmentation de l'autorité démocratique des acteurs. Toutefois, la gouvernance assume une dynamique de négociation, même en matière de réglementation entre l'État, la région, le local, l'école et le marché, faite pour répondre à la construction d'intérêt général, qui n'est pas plus entièrement défini par l'Etat, mais construit en ensemble avec les divers forces politiques, économiques, éducatives et sociales. L‘étude indique que la décentralisation est minée par le gouvernement central quand il ‗re-centralise‘ les décisions et les conditions locales, avec la fermeture de la plupart des écoles du premier cycle et avec des groupements verticaux d‘écoles. À leur tour, certaines politiques éducatives telles que ‗l'école à temps plein‘ forcé les municipalités à accroître leurs ressources techniques et humaines, de construire de nouvelles infrastructures éducatives. Les politiques éducatives ont commencé à être conçues selon une matrice hybride, qui vise à la municipalisation de l'éducation - de l'école maternelle et de toute l'école basique - d'une part ; et de promouvoir la situation de «quasi-marché» avec la privatisation de secteurs et le financement de plusieurs institutions - qui offrent des services dans l'éducation -, d‘autre part.

Biting activity of Aedes scapularis (Rondani) and Haemagogus mosquitoes in Southern Brazil (Diptera: Culicidae)

The biting activity of a population of Aedes scapularis (Rondani), Haemagogus capricornii Lutz and Hg. leucocelaenus (Dyar and Shannon) in Southern Brazil was studied between March 1980 and April 1983. Data were obtained with 25-hour human bait catches in three areas with patchy residual forests, named "Jacaré-Pepira", "Lupo" Farm, and "Sta. Helena" Farm, in the highland region of S. Paulo State (Brazil). Data obtained on Ae. scapularis were compared with those formerly gathered in the "Ribeira'' Valley lowlands, and were similar, except in the "Lupo" Farm study area, where a precrepuscular peak was observed, not recorded at the "Jacaré-Pepira" site or in the "Ribeira" Valley. In all the areas this mosquito showed diurnal and nocturnal activity, but was most active during the evening crepuscular period. These observations support the hypothesis about the successful adaptation of Ae. scapularis to man-made environments and have epidemiological implications that arise from it. As for Haemagogus, results obtained on the "Lupo" and "Sta. Helena" regions agree with previous data obtained in several other regions and show its diurnal activity. The proximity of "Lupo" Farm, where Hg. capricornii and Hg. leucocelaenus showed considerable activity, to "Araraquara" city where Aedes aegypti was recently found, raises some epidemiological considerations about the possibility of urban yellow fever resurgence.

Studies on mosquitoes (Diptera: Culicidae) and anthropic environment: 1- Parity of blood seeking Anopheles (Kerteszia) in South-Eastern Brazil

Populations of Anopheles (Kerteszia) were sampled fortnightly over a one-year period (August 1991 to July 1992) at Ribeira Valley, S. Paulo State, Brazil. Indoor and outdoor collections were made on human bait at evening crepuscular period. The Polovodova technique for age grading was applied to 3,501 females of Anopheles cruzii and to 416 females of An. bellator. That sample represented 34.4% of the total number of mosquitoes collected. The most abundant species found was An. cruzii. However, An. bellator showed an endophagy that was almost three times greater than that of An. cruzii. The overall parous rate was 25.4% and uniparity was practically dominant one. A proportion of 26.9% of An. cruzii and 12.0% of An. bellator were found to be uniparous. Only three outdoor females of the former species (0.1%) showed biparity. Parity of An. cruzii was higher in females caught outdoors than in those caught indoors. Nevertheless, 497 nulliparous females examined (417 cruzii and 80 bellator) had ovaries that had advanced to Christophers and Mer stages III to V. These results imply that these females had already practised hematophagy. Relating these results to those from the parous females, a high statistical significance was found, leading to the conclusion that gonothophic discordance is a common pattern among these anophelines. Further, these results obtained with human bait catches strongly suggest that nearly 38.0% of these host-seeking females had already taken at least one previous blood-meal. So it is possible that enough time could thus be available for the plasmodian development in the vectors.

Studies on mosquitoes (Diptera: Culicidae) and anthropic environment: 2 - Immature stages research at a rice irrigation system location in South-Eastern Brazil

A relation between a rice irrigation system and mosquito breeding was established in a study undertaken at the Ribeira Valley Experimental Station, from January through December 1992. Flooding favoured Anopheles (Nyssorhynchus) and Culex (Melanoconion) species, while empty paddies condition were propitious to Aedes scapularis and Culex (Culex) species. Compared with a more primitive area of the same region, several species showed high a degree of adaptation to the anthropic environment. Among them, Anopheles albitarsis, a potential malaria vector that breeds in the irrigation system, has shown immature stage production thirteen times higher than at the natural breeding sites. In addition, Ae. scapularis, An. oswaldoi, Cx. bastagarius, and Cx. chidesteri presented high levels of synanthropy.

Studies on mosquitoes (Diptera: Culicidae) and anthropic environment: 3- Survey of adult stages at the rice irrigation system and the emergence of Anopheles albitarsis in South-Eastern, Brazil

A study of adult Culicidae ecology was carried out from January 1992 through January 1993 at the rice irrigation system of the Ribeira Valley Experimental Station. The adaptation of Anopheles albitarsis to the anthropic environment became evident through the adult collections made at its various habitats represented by the irrigation system and the edge of the residual pond, as well as at those made within the local patchy residual woods. Other potential disease vectors were prevalent in the irrigated system too. There were Aedes scapularis, Culex nigripalpus and Cx. ribeirensis that were collected at various habitats. Remarkable differences among their prevalences were obtained such as between the natural forest and anthropic environments. In the former An. albitarsis was practically non-existent, thus suggesting that it might be considered as eusynathropic. As the populations of other species seemed to increase in the anthropic environment, they may be regarded as hemisynanthropes. Observations suggest the hypothesis that the development of irrigated land may be a factor in the emergence of An. albitarsis, and some other species, as well as the possibility of an increase in the transmission of mosquito-borne diseases such as malaria.

Studies on mosquitoes (Diptera: Culicidae) and anthropic environment: 4 - Survey of resting adults and synanthropic behaviour in South-Eastern, Brazil

Resting adults Culicidae were collected from January 1992 through January 1993 in several habitats of the Ribeira Valley region. The diversity of species found among them suggested that the vegetation remaining within human settlements favored the survival and the population increase of some mosquitoes. Among there are: Ae. scapularis, Ae. serratus, Cx. (Culex), Cx. nigripalpus and Cx. (Melanoconion) such as Cx. ribeirensis. That preservation role may be attributed to the rearing of livestock and the consequent increase in the number of blood sources. These species may be classified as hemisynanthropes and Cx. oedipus apparently evolving to the eusynanthropic status. On the other hand, An. cruzii showed an asynanthropic behaviour, with a low degree of survival in the modified human environment. Epidemiological implications of the data are mentioned.

Studies on mosquitoes (Diptera: Culicidae) and anthropic environment: 7- Behaviour of adults Nyssorhynchus anophelines with special reference to Anopheles albitarsis s.l. in South-Eastern Brazil

Results obtained with catches performed at several sites of the Ribeira Valley, SP (Brazil) are reported. Collections with Shannon type traps showed a concentration of An.albitarsis s.l. in the Experimental Farm of Pariquera-Açu County, associated with the development of irrigated rice cultivation. Two species of the complex, named A and B, were recognized. Species B predominated in the samples. Indoor and outdoor crepuscular human bait captures were performed a the domiciliary environment. The two species showed a generally low William's media valve of 0.2, the highest value obtained was 1.6. No differences were found between indoor and outdoor behaviours between the two species of the complex.

Studies on mosquitoes (Diptera: Culicidae) and anthropic environment: 8- Survey of adult behaviour of Spissipes Section species of Culex (Melanoconion) in South-Eastern Brazil

A study of Spissipes Section of Culex (Melanoconion) adults behaviour was carried out from August 1992 through December 1993 in human dominated (anthropic) environment in the Ribeira Valley, S.Paulo State, Brazil. By sampling at several sites it the dominance of Culex ribeirensis and Cx. sacchettae became evident even through a total number of ten species was recorded. Those two mosquitoes showed a clear tendency to frequent the domiciliary environment where they were caught, both indoor and outdoor, through the use of the human bait. In the outside environments, the residual patchy forests seems to display a concentration role, from which these adults spread to the open land and reach the dwellings. As their vector competence has been demonstrated through the virus isolations in natural conditions, it is advisable to pay attention to the presence of these mosquitoes in the man-made environment.

Studies on mosquitoes (Diptera: Culicidae) and anthropic environment: 9- Synanthropy and epidemiological vector role of Aedes scapularis in South-Eastern Brazil

Behaviour comparisons of Aedes scapularis and Ae. serratus are presented. Results were obtained by sampling Aedes adult mosquitoes at several places in the rural anthropic environment in the Ribeira Valley region of S. Paulo State, Brazil. Aedes dominance was shared by those two species, but Ae. scapularis Sshowed a clear tendency to frequent the modified environment, while Ae. serratus was to be found in the more preserved ones, here represented by the vestigial patchy forests. Regarding the open cultivated land and the dwelling environments, Ae. scapularis preponderates. Considering the regional developmental phases, this mosquito showed a remarkable increase in the modified environment differently from Ae. serratus that underwent a considerable decrease in migrating from the forest to the anthropic environment. As a consequence of these results it is reasonable to conclude that Ae. scapularis may be considered as an epidemiologically efficient vector and that it quite probably played this role in the Rocio encephalitis and other arbovirus epidemics.

Studies on mosquitoes (Diptera: Culicidae) and anthropic environment: 10- survey of adult behaviour of Culex nigripalpus and other species of Culex (Culex) in South-Eastern Brazil

A survey of adult behaviour of Culex (Culex) species was carried out from August 1992 through December 1993 in a human modified (anthropic) environment in the Ribeira Valley, S.Paulo State, Brazil. Culex nigripalpus dominated the catches at several sites and it's tendency to increase in the anthropic environment became quite clear. Nevertheless no high level of synanthropy was demonstrated. So it seems that the mosquito may have a restricted role in natural arbovirus cycles. Nonetheless, Cx. nigripalpus must be considered a potential vector of arboviruses, especially St. Louis encephalitis virus outside dwellings.

Studies on mosquitoes (Diptera: Culicidae) and anthropic environment. 12- Host-seeking behaviour of Anopheles albitarsis s.l. in South-Eastern Brazil

Results obtained with Anopheles albitarsis s.l. catches mainly performed through human bait at the Ribeira Valley region, SP (Brazil), are reported. Two species of the complex were recognized, namely An. albitarsis s.s. and species B. This latter predominated both in the rice fields and in the dwelling environments. The crepuscular rhythms showed an unimodal sunset pattern with most blood-seeking females caught during dusk. The absence of differences between indoor and outdoor behavior was confirmed for both species of the complex.

A comunicação online das organizações culturais. A utilização de novas ferramentas pelas companhias de teatro de Lisboa e Vale do Tejo de 2000 a 2013

Nos dias de hoje, ferramentas como o Facebook, o Twitter e o YouTube fazem parte do quotidiano. Desde o recente virar do século até ao presente, a sociedade transformou-se. Usamos cada vez mais a Internet. Nela pesquisamos informação e partilhamos conteúdos, sejam eles textos, fotos ou vídeos. As novas ferramentas de comunicação online trouxeram uma maior interatividade entre aquele que emite uma mensagem e aquele que a recebe. Nesta investigação procura-se analisar quais e como é que as novas ferramentas de comunicação online são utilizadas pelas organizações culturais, nomeadamente, pelas companhias de teatro de Lisboa e Vale do Tejo, entre 2000 e 2013. Ao longo do enquadramento teórico são abordadas questões como a comunicação das organizações, a comunicação online das mesmas, a utilização das novas ferramentas online por parte de companhias de teatro e o que são considerados sites, media sociais e redes sociais. Entre várias referências, serão citados Grunig e Hunt (1984) que apresentam o modelo de comunicação de dois sentidos simétricos, assim como Phillips e Young (2009) que abordam as diferentes ferramentas de comunicação online. São ainda apresentados estudos relativos à utilização destas ferramentas por parte das organizações artísticas, elaborados pela MTM London (2009) e pelo Australia Council for the Arts (2011). A presente investigação tem por base a observação e acompanhamento das ferramentas de comunicação online utilizadas pelas companhias de teatro, inquéritos aos produtores dessas companhias e entrevistas a alguns dos seus diretores. Com este trabalho pretende-se verificar que ferramentas estão a ser utilizadas pelas companhias, com que regularidade, quem nas companhias gere essas ferramentas, quais as vantagens percecionadas, entre outros aspetos.
