Convergências e/ou divergências no sistema de crenças e práticas parentais: comparação entre duas amostras amazônicas

A proposta desta pesquisa foi identificar convergências e divergências nas crenças, metas de socialização e práticas de cuidados parentais em dois contextos ecológicos amazônicos, buscando analisar a relação entre fatores biológicos e ecoculturais. Participaram da pesquisa 99 mães de duas localidades: Belém – capital (CEU – contexto ecológico urbano – N=50) e Santa Bárbara (CENU – contexto ecológico não urbano – N=49), com idade superior a 18 anos com pelo menos uma criança com idade entre 0 e 6 anos . Os dados foram coletados por meio de entrevistas em que se aplicavam questionários e para análise destes foram utilizados critérios estatísticos e o respaldo teórico da Psicologia Evolucionista. Os dados indicaram que as comunidades estudadas em relação aos dados socio-demográficos diferem de forma sistemática uma da outra, em função dos níveis de desenvolvimento tecnológico e diferentes organizações para o contexto social. O mundo social das crianças de CENU e de CEU representam contextos desenvolvimentais que oferecem diferentes oportunidades. A literatura aponta que as trocas sociais estabelecidas entre crianças e cuidadores podem refletir sobre o desenvolvimento da criança em relação ao aspecto cognitivo, emocional e social. Os resultados encontrados indicam que as mães de CEU apesar de terem sido mais autônomas que as de CENU, foram ao mesmo tempo mais relacionais que as mesmas, demonstrando que talvez as mudanças que atingem os contextos, ocorram com mais rapidez em ambientes urbanizados. Além disso, os dados parecem indicar que os contextos por estarem em um momento de transição passam de um modelo interdependente para um modelo autônomo-relacional. Entretanto, foi possível perceber que as idéias que as mães possuem sobre a importância de determinadas ações nem sempre refletem suas práticas. Em relação aos cuidados primários as mães parecem valorizar e realizar de igual modo. Em relação ao Contato corporal as mães de CENU valorizam mais que as mães de CEU. Em estimulação corporal o resultado foi bastante interessante, pois os itens que CEU deu mais importância e praticou menos, foram os mesmos itens em que CENU deu menos importância e praticou mais. No que tange a estimulação por objeto as mães de CEU dão mais importância as praticas do que as realizam e vice-versa acontece em CENU. Ao sistema face-a-face foi atribuída maior importância pelas mães de CEU. Os dados apresentados sugerem que as mães de ambos os contextos estão utilizando estratégias parentais distais e proximais ao mesmo tempo, ou seja, desejam que seus filhos se tornem auto-suficientes, mas também desejam que os mesmos sejam respeitosos e obedientes. Além disso, os resultados aqui encontrados confirmam que os quatro sistemas descrevem as experiências interacionais das crianças e expressam a ênfase cultural de combinações e estilos particulares. Não foram encontradas diferenças marcantes nas crenças e práticas de cuidados maternos entre CEU e CENU, o que nos levou a considerar que as crenças parentais, em consequência à adaptação ao contexto, variaram menos conspicuamente nas cidades escolhidas do que entre outras cidades examinadas em outros estudos. Outra questão bastante interessante encontrada foi o resultado relativo ao nível de instrução das mães de CEU e a valorização de metas relacionais, pois de acordo com a hipótese na literatura o nível educacional das mães torna-se uma variável importante em relação às metas de socialização. CENU demonstrou uma tendência para metas e práticas relacionais. Isso se deve ao modo de vida mais próximo do protótipo de interdependência que este contexto apresenta, no qual as mães tendem a valorizar as normas e regras determinadas pela família ou grupo ao qual pertencem. Os resultados referentes ao CEU não confirmaram a hipótese de que ele apresentaria mais metas e práticas voltadas para a independência, sendo percebido que Belém apresenta tanto características do modelo de independência como de interdependência. Presume-se que CEU e CENU são contextos que passam por mudanças, uma vez que as mães podem acreditar em uma coisa e na realidade agir de outra forma.

Planting coconuts in Indian villages: ethnoecological aspects and evaluation of a "sustainable development" project

Apesar de cientistas e tomadores de decisão abraçarem o conceito geral de "desenvolvimento sustentável", há pouco acordo sobre como se atingir esta meta em situações específicas. Assim, projetos de desenvolvimento sustentável são amplamente criticados por etno-cientistas quanto à forma como são inter-culturalmente formulados. Aqui reportamos um caso controverso de plantio de coco-da-Bahia em aldeias Kayapó do sul do Pará, e fazemos a nossa autocrítica. Nós partimos da premissa de que o reflorestamento e o estado geral de saúde/nutrição caminham lado a lado. Portanto, o desenvolvimento da cultura de cocos por si só deve contribuir para a conservação da floresta no longo prazo e, simultaneamente, contribuir para o bom estado nutricional do povo Kayapó que protege a floresta da ameaça de práticas não-sustentáveis. Nós buscamos descobrir como que o comportamento dos Kayapó afeta o desenvolvimento da cultura de cocos quando amparada com suporte externo. Nós apresentamos resultados de duas viagens de campo para a terra Kayapó, onde detectamos fatores sócio-ecológicos relevantes para o sucesso de nosso projeto de apoio à cultura de coqueiros nas aldeias indígenas. Primeiro, em novembro de 2007, nós visitamos as aldeias Kikretum, Moikarakô e Aukre (dentre 10 aldeias que receberam mudas de coqueiros de nosso programa de apoio) para entregar um segundo carregamento de mudas de coqueiro (o primeiro carregamento aconteceu em abril de 2006). E descrevemos quantitativamente um aspecto do comportamento dos dispersores de sementes de coco (os Kayapó). Especificamente, como as palmeiras pré-existentes nas aldeias são distribuídas dentre as famílias dos índios e como este carregamento sobreviveu a fatores etno-ecológicos. Segundo, em julho de 2008 nós visitamos as aldeias Kokraimoro e Pykararankre e estimamos a posição dos coqueiros pré-existentes e dos novos em relação a outras árvores cultivadas, fazendo uso de censos partindo do centro das aldeias para seus limites exteriores. Nas três aldeias indígenas visitadas em 2007, virtualmente todos os coqueiros pré-existentes pertenciam a poucas famílias e a distribuição de frutos era, na maior parte dos casos, altamente concentrada dentre os membros destas famílias. Entretanto, assumindo que todos os coqueiros jovens que sobreviveram ao primeiro ano chegarão à maturidade (do primeiro carregamento em abril de 2006), eles representam um aumento considerável no numero projetado de coqueiros adultos nas três aldeias visitadas (48, 195 e 101% em Kikretum, Moikarakô e Aukre, respectivamente). E uma redução substancial na desigualdade de acesso aos cocos. Na expedição de 2008, encontramos que os índios geralmente plantam coqueiros bem próximos das suas casas onde a competição com outras árvores cultivadas podem limitar o desenvolvimento das palmeiras.

Sustainable development in the BRICS countries: an efficiency analysis by data envelopment

There is much concern about the social and environmental impacts caused by the economic growth of nations. Thus, to evaluate the socio-economic performance of nations, economists have increasingly addressed matters related to social welfare and the environment. It is within the scope of this context that this work discusses the performance of countries in the BRICS group regarding sustainable development. The objective of this study regards evaluating the efficiency of these countries in transforming productive resources and technological innovation into sustainable development. The proposed objective was achieved by using econometric tools as well as the data envelopment analysis method to then create economic, environmental, and social efficiency rankings for the BRICS countries, which enabled to carry out comparative analyses on the sustainable development of those countries. The results of such assessments can be of interest for more specific scientific explorations.

Contos de fadas: recurso educativo para crianças com deficiência intelectual

Studies show the psychological contribution of fairy tales regarding the child's development as one of the best plumbers of existential problems, appeasing it by acting as an outlet for their anguish, anxieties, and fears, engendering greater emotional balance. Thus, through researches in the literature, it was established as objective to seek information about the functionality of the fairy tales in the educational process of students with intellectual disabilities who presents challenging behaviors. Among the tales, the Brothers Grimm are suggested to be used as an educational resource. It was possible to say that, through the symbolic mediation in the imaginary of children with intellectual disabilities, educational work with fairy tales evokes significant benefits.

An integrated approach of software development and test processes to distributed teams

The Distributed Software Development (DSD) is a development strategy that meets the globalization needs concerned with the increase productivity and cost reduction. However, the temporal distance, geographical dispersion and the socio-cultural differences, increased some challenges and, especially, added new requirements related with the communication, coordination and control of projects. Among these new demands there is the necessity of a software process that provides adequate support to the distributed software development. This paper presents an integrated approach of software development and test that considers distributed teams peculiarities. The approach purpose is to offer support to DSD, providing a better project visibility, improving the communication between the development and test teams, minimizing the ambiguity and difficulty to understand the artifacts and activities. This integrated approach was conceived based on four pillars: (i) to identify the DSD peculiarities concerned with development and test processes, (ii) to define the necessary elements to compose the integrated approach of development and test to support the distributed teams, (iii) to describe and specify the workflows, artifacts, and roles of the approach, and (iv) to represent appropriately the approach to enable the effective communication and understanding of it.

Introducing education for sustainable development in the undergraduate laboratory: quantitative analysis of bioethanol fuel and its blends with gasoline by using solvatochromic dyes

The concept of Education for Sustainable Development, ESD, has been introduced in a period where chemistry education is undergoing a major change, both in emphasis and methods of teaching. Studying an everyday problem, with an important socio-economic impact in the laboratory is a part of this approach. Presently, the students in many countries go to school in vehicles that run, at least partially, on biofuels; it is high time to let them test these fuels. The use of renewable fuels is not new: since 1931 the gasoline sold in Brazil contains 20 to 25 vol-% of bioethanol; this composition is being continually monitored. With ESD in mind, we have employed a constructivist approach in an undergraduate course, where UV-vis spectroscopy has been employed for the determination of the composition of two fuel blends, namely, bioethanol/water, and bioethanol/gasoline. The activities started by giving a three-part quiz. The first and second ones introduced the students to historical and practical aspects of the theme (biofuels). In the third part, we asked them to develop a UV-vis experiment for the determination of the composition of fuel blends. They have tested two approaches: (i) use of a solvatochromic dye, followed by determination of fuel composition from plots of the empirical fuel polarity versus its composition; (ii) use of an ethanol-soluble dye, followed by determination of the blend composition from a Beer's law plot; the former proved to be much more convenient. Their evaluation of the experiment was highly positive, because of the relevance of the problem; the (constructivist) approach employed, and the bright colors that the solvatochromic dye acquire in these fuel blends. Thus ESD can be fruitfully employed in order to motivate the students; make the laboratory "fun", and teach them theory (solvation). The experiments reported here can also be given to undergraduate students whose major is not chemistry (engineering, pharmacy, biology, etc.). They are low-cost and safe to be introduced at high-school level.

What Happened to Participation? Urban Development and Authoritarian Upgrading in Cairo's Informal Neighbourhoods

Participation appeared in development discourses for the first time in the 1970s, as a generic call for the involvement of the poor in development initiatives. Over the last three decades, the initial perspectives on participation intended as a project method for poverty reduction have evolved into a coherent and articulated theoretical elaboration, in which participation figures among the paraphernalia of good governance promotion: participation has acquired the status of “new orthodoxy”. Nevertheless, the experience of the implementation of participatory approaches in development projects seemed to be in the majority of cases rather disappointing, since the transformative potential of ‘participation in development’ depends on a series of factors in which every project can actually differ from others: the ultimate aim of the approach promoted, its forms and contents and, last but not least, the socio-political context in which the participatory initiative is embedded. In Egypt, the signature of a project agreement between the Arab Republic of Egypt and the Federal Republic of Germany, in 1998, inaugurated a Participatory Urban Management Programme (PUMP) to be implemented in Greater Cairo by the German Technical Cooperation (Deutsche Gesellschaft für Technische Zusammenarbeit, GTZ) and the Ministry of Planning (now Ministry of Local Development) and the Governorates of Giza and Cairo as the main counterparts. Now, ten years after the beginning of the PUMP/PDP and close to its end (December 2010), it is possible to draw some conclusions about the scope, the significance and the effects of the participatory approach adopted by GTZ and appropriated by the Egyptian counterparts in dealing with the issue of informal areas and, more generally, of urban development. Our analysis follows three sets of questions: the first set regards the way ‘participation’ has been interpreted and concretised by PUMP and PDP. The second is about the emancipating potential of the ‘participatory approach’ and its ability to ‘empower’ the ‘marginalised’. The third focuses on one hand on the efficacy of GTZ strategy to lead to an improvement of the delivery service in informal areas (especially in terms of planning and policies), and on the other hand on the potential of GTZ development intervention to trigger an incremental process of ‘democratisation’ from below.

Development discourse in Romania: from Socialism to EU Membership

With their accession to the European Union, twelve new countries - Romania among them - (re)entered the international community of international donors. In the history of development aid this can be seen as a unique event: it is for the first time in history that such a large number of countries become international donors, with such short notice and in such a particular context that sees some scholars announcing the ‘death’ of development. But in spite of what might be claimed regarding the ‘end’ of the development era, development discourse seems to be rather vigorous and in good health: it is able to extert an undeniable force of attraction over the twelve countries that, in a matter of years, have already convinced themselves of its validity and adhered to its main tenets. This thesis collects evidence for improving our understanding of this process that sees the co-optation of twelve new countries to the dominant theory and practice of development cooperation. The evidence collected seems to show that one of the tools employed by the promoters of this co-optation process is that of constructing the ‘new’ Member States as ‘new’, inexpert donors that need to learn from the ‘old’ ones. By taking a case-study approach, this thesis gathers data that suggests that conceiving of the ‘twelve’ as ‘new’ donors is both historically inaccurate and value-ladden. On one hand, Romania’s case-study illustrates how in the (socialist) past at least one in the group of the twelve was particularly conversant in the discourse of international development. On the other hand, the process of co-optation, while being presented as a knowledgeproducing process, can also be seen as an ignorance-producing procedure: Romania, along with its fellow new Member States, takes the opportunity of ‘building its capacity’ and ‘raising its awareness’ of development cooperation along the line drawn by the European Union, but at the same time it seems to un-learn and ‘lower’ its awareness of development experience in the (socialist) past. This is one possible reading of this thesis. At a different level, this thesis can also be seen as an attempt to account of almost five decades of international development discourse in one specific country – Romania – in three different socio-political contexts: the socialist years (up to the year 1989), the ‘transition years’ (from 1989 to the pre-accession years) and the membership to the European Union. In this second reading, the thesis seeks to illustrate how – contrary to widespread beliefs – before 1989 Romania’s international development discourse was particularly vivid: in the most varied national and international settings President Ceausescu unfolded an extensive discursive activity on issues pertaining to international development; generous media coverage of affairs concerning the developing countries and their fight for development was the rule rather than the exception; the political leadership wanted the Romanians not only to be familiarized with (or ‘aware of’ to use current terminology) matters of underdevelopment, but also to prove a sense of solidarity with these countries, as well as a sense of pride for the relations of ‘mutual help’ that were being built with them; finally, international development was object of academic attention and the Romanian scholars were able not only to reflect on major developments, but could also formulate critical positions towards the practices of development aid. Very little remains of all this during the transition years, while in the present those who are engaged in matters pertaining to international development do so with a view of building Romania as an EU-compliant donor.

Reconceptualising professional development in early childhood education. A study on teachers' professionalism carried out in Bologna province.

The research undertaken for this doctoral thesis explores the issue of teachers professionalism within pre-school institutions. The issue of early childhood professionalism has become increasingly important in the academic debate over the last decade as it is documented by a growing body of research published on the topic both nationally (Contini & Manini, 2007; Bondioli & Ferrari, 2004) and internationally (Peeters, 2008; Urban & Dalli, 2008; Urban, 2010). The study presented in this thesis aims at investigating teachers’ conceptualisations of professionalism by focusing on their understandings of educational work. The idea standing at the core of this research is that exploring the concept of professionalism from a ground-up perspective could lead to important reflections for a re-conceptualisation of professional development as a space for change directed from within institutions. The study is framed within a broadly sociological concern that inform the data analysis by contextualising the issue of early childhood professionalism in the contemporary socio-political arena. The research involves sixty teachers operating in state, municipal and private pre-school institutions located in Bologna province that took part to focus groups and interviews. The empirical materials, consisting of oral and written statements, are interpreted through phenomenographical analysis that gives account of how features of professionalism vary across the different institutional settings in which they are played out. This thesis, written in English and informed by an European research background, offers a contribution to the furthering of systemic approaches to the investigation of early childhood education professionalism in the context of the national and international academic debate.

Bridging innovation, nature and tradition: assessment of strategies for rural tourism development in Maramureş (Romania)

In the frame of EU rural policy, always more oriented towards environmental concerns and green livelihoods, Romania stands out for the predominance of rural areas and high nature value farming. The country has to face the challenge of joining the modernization process of rural farming systems with the valorization of local assets. Tourism has emerged as one of the main drivers of change and contributors for a sustainable exploitation of local resources. Rural tourism (RT) can foster the enhancement of the territorial capital (TC), the preservation of public goods (PGs) and the promotion of a more environmental oriented livelihood. The research focuses on a case study area, two valleys from Maramureş, where environmental approaches as diversification strategies are partially explored. The work investigates the role of tourism initiatives for the promotion of green oriented practices. The first part of the work is based on a literature review and interdisciplinary analysis of secondary data to identify the key issues: from rural development policy, to the concept of TC, of PGs and RT. The Romanian development programmes and related strategies are investigated; afterwards the characteristics of the County and the role of RT as diversification and valorisation policies is considered. The second part is based on the collection of primary data through interviews to different local stakeholders (farmers owners of rural guesthouses, local administrators, networks and artisans). The main frequencies are analyzed, a cluster analysis is computed to evaluate the similarities within the most representative groups and a comparative analysis is carried out between the two Valleys. The frame of the analysis is based on a set of indicators following the dimensions of the TC, to assess the characteristics of the local stakeholders and to outline the perception about the local PGs and on the adopted strategies to manage the territory. Final considerations are elaborated and few scenarios are outlined, giving relevance to the importance of improving awareness and creating embeddedness among public-private local stakeholders and resources as a tool for a socio-economic and environmental development of the area.

Pedofilia e pedopornografia online: una ricerca socio-criminologica nella realtà italiana e francese

Una delle realtà criminali che ha maggiormente fruito delle innovazioni introdotte dalla “società dell’Informazione” è, senza dubbio, quella dell’abuso sessuale sui minori. Tra le differenti forme di abuso sessuale sui minori, si è scelto di affrontare il fenomeno della pedopornografia online in ragione del preoccupante diffondersi di questa forma di criminalità che, grazie all’implementazione delle tecnologie dell’informazione, ha assunto caratteri nuovi, per alcuni versi difformi dai “tradizionali” profili della pedofilia, che sollevano interrogativi e nuove sfide sia sul versante della repressione di queste condotte illecite, sia sul piano della prevenzione. Nell'ambito di questo contributo, saranno esaminate in particolare le politiche penali elaborate in due diverse realtà nazionali, l'Italia e la Francia, a partire da differenti punti di vista e ponendo particolare attenzione agli strumenti, normativi ed operativi, introdotti per reprimere lo sfruttamento sessuale dei minori legato alla dimensione virtuale.

The ecological and socio-economic role of Prosopis juliflora in Eritrea

In Eritrea findet eine rasche Verbreitung von Prosopis (juliflora) statt, die sich negativ auf die Naturresourcen als auch die sozio-ökonomische Lage der ländlichen Bevölkerung auswirkt. Die Landbevölkerung Eritrea's ist davon überzeugt, dass die Pflanze vor allem die Ernährungssicherung beeinträchtigt und will deshalb, dass sie ausgerottet wird. Die vorliegende Dissertation beschreibt die Auswirkung von Posopis auf lokale Öko- und Wirtschaftssysteme und zieht Vergleiche mit der diesbezüglichen Situation in anderen Ländern. Im Weiteren stellt sie einen Prosopis Management-Plan vor, dessen Ziel es ist, die zunehmende Verbreitung zu verhindern. Auch liefert sie eine Gegenüberstellung der Ansichten von wissenschaftlichen Experten einerseits und Bauern und Nomaden andrerseits. Sie zeigt auf, dass die weit verbreitete Annahme der Experten das Problem Prosopis durch ökonomische Nutzung ("eradication by utilisation") in Schach halten zu können, fraglich ist.

Development, degeneration and neural network of the bodily self

The question addressed by this dissertation is how the human brain builds a coherent representation of the body, and how this representation is used to recognize its own body. Recent approaches by neuroimaging and TMS revealed hints for a distinct brain representation of human body, as compared with other stimulus categories. Neuropsychological studies demonstrated that body-parts and self body-parts recognition are separate processes sub-served by two different, even if possibly overlapping, networks within the brain. Bodily self-recognition is one aspect of our ability to distinguish between self and others and the self/other distinction is a crucial aspect of social behaviour. This is the reason why I have conducted a series of experiment on subjects with everyday difficulties in social and emotional behaviour, such as patients with autism spectrum disorders (ASD) and patients with Parkinson’s disease (PD). More specifically, I studied the implicit self body/face recognition (Chapter 6) and the influence of emotional body postures on bodily self-processing in TD children as well as in ASD children (Chapter 7). I found that the bodily self-recognition is present in TD and in ASD children and that emotional body postures modulate self and others’ body processing. Subsequently, I compared implicit and explicit bodily self-recognition in a neuro-degenerative pathology, such as in PD patients, and I found a selective deficit in implicit but not in explicit self-recognition (Chapter 8). This finding suggests that implicit and explicit bodily self-recognition are separate processes subtended by different mechanisms that can be selectively impaired. If the bodily self is crucial for self/other distinction, the space around the body (personal space) represents the space of interaction and communication with others. When, I studied this space in autism, I found that personal space regulation is impaired in ASD children (Chapter 9).
