In the last 50 years, Mexico, like many other countries in Latin America, Asia and Africa, has experienced accelerated urban growth. Urban growth has been accompanied by an increase in urban poverty. While the spatial distribution of poverty in urban areas in Mexico is varied, new settlements that tend to grow in the peri-urban hinterland of cities are largely associated with poverty. This is because inexpensive, but mostly illegal, agricultural land (ejido or private) has been alienated to satisfy the demands of low income population for housing. The focus of this study lay in the Metropolitan Area of Mexico City (MAMC), which is the habitat of diverse low-income groups. Among those groups are the campesinos (people with rural background engaged totally or partially in agricultural livelihoods). Some studies have suggested that campesinos are very vulnerable to urban growth, since population expansion has put severe pressure on their agricultural land, which, despite its marginal value, is used to produce crops for either semi-commercialisation or subsistence. Although such research has showed how poor campesinos have engaged in non-agricultural activities to make a living and how land and their communities are threatened by urban growth due to speculative pressures on land and/or environmental deterioration, little is known about the impact of urban growth in the process of impoverishment of campesinos living in peri-urban areas. This study aims to understand how the growth of the MAMC affects poverty in campesinos’ households, in order to recommend directions for poverty reduction. Three villages in Chalco municipality, which is situated in the peri-urban fringe of Mexico City, were selected as the study area. Based on the development of a conceptual framework, this study considered three interconnected elements underpinning poverty: multi-dimensionality, complexity and dynamism. For this reason, the Sustainable Livelihoods approach was selected as an analytical tool, as it provided a flexible analytical framework that encompasses all those elements. The study is divided in three stages. In the first stage (namely documental investigation), a series of published and unpublished written materials were reviewed to determine how the growth of the MAMC transformed the nature and availability of resources in Chalco municipality from 1970 to 2000. This stage was followed by the empirical investigation that aimed to examine how those transformations affected campesinos’ assets (human, natural, physical, productive and social), the strategies they used to adapt to such changes, and how they perceived changes in poverty status. Accordingly, for this stage, quantitative and qualitative longitudinal and cross-sectional data were collected from 110 campesinos’ households living in the study area in 1997 and 2003 by using structured questionnaires. Qualitative data were also collected by using semi-structured interviews from 34 campesinos’ households in 2000. The final stage, called recommendations, involved the synthesis of the results of the documental and empirical investigations and suggests a series of directions for poverty reduction in campesinsos’ households in the study area. The documental and empirical investigations revealed that changes in asset ownership, between 1997 to 2003, depended on both transformation in the nature and availability of resources in Chalco and intra-household organization. Fundamental transformations in socio-demographic, economic, natural, physical and political/organisational resources of Chalco municipality were mainly, but not exclusively, associated with the growth of the MAMC. Climatic and physical characteristics of Chalco were also evident. To respond to such changes, campesinos implemented a series of strategies to get access to resources. Such strategies were based on campesinos’ needs, priorities and the portfolio of assets available, and their functionality. It was clear that campesinos depleted some existing assets to acquire urban assets and preserve their rural assets. In some instances, such strategies led campesinos’ families to satisfy their basic needs and, therefore, perceive themselves as non-poor. However, in other instances, such strategies prevented families from meeting their needs, leading them to the perception of being poor. The recommendation was made that in order to reduce poverty among campesinos in the study area, it was necessary to identify different alternatives to support their urban and rural assets and certain of their strategies that improve the wellbeing of individuals, families and communities and mitigate constraints to meeting their goals.

Following a healing period of 3 months, healing abutments were installed and 45 days after cotton ligatures were placed and oral-cleaning procedures abolished for 2 months to induce vertical bone loss of about 40%. Microbial samples were with paper points on day of ligature placement and after 20, 40 and 60 days. The total number of cultivable bacteria and proportions of A. actinomycetemcomitans, Bacteroides forsythus, P. gingivalis, P. intermediate, Campylobacter sp., Capnocytophaga sp., Fusobacterium sp., Peptostreptococcus micros, Enteric Gram-negative rods, beta-hemolytic Streptococcus, Eikenella corrodens and Candida sp. were analyzed. No significant microbiological differences were observed among the different surfaces (p>0,05). Pg was not detected in the time 0; already in the times 20 and 40 were detected in 12 dental implants (4 Ticp, 4 HA, 2 TPS and 1 acid-etched surface) and in the period 60 days, in 9(2 Ticp, 3 HA, 2 TPS and 1 acid-etched surface), tends smaller affinity to eh surface with acids-etched surface. Pi was detected in 5 implants (2 Ticp, 2 HA and 1 acid-etched surface) in the period 0 and in 100% of implants in other periods. Fusobacterium sp. was detected in all the periods, tends a larger affinity to HA. Beta-hemolytic Streptococcus was detected in 6 implants (3 Ticp, 1 TPS and 2 HA) in the period 0 and 30, 26 and 24...

Palmeiras têm sido utilizadas como modelo na avaliação de como os processos de dispersão e predação de sementes estão sendo afetados pela fragmentação e alteração das florestas tropicais. Este trabalho se propõe a analisar alguns dos processos ecológicos que envolvem Syagrus romanzoffiana (palmeira jerivá) dentro de ecossistemas insulares em Santa Catarina. Os locais estudados foram o Parque Municipal da Lagoa do Peri (PMLP), na Ilha de Santa Catarina, e a Ilha do Campeche (IC), consistindo dois ambientes de Florestas Ombrófila Densa de diferentes tamanhos. O PMLP possui 2000ha e é o fragmento mais conservado da Ilha de Santa Catarina, abrigando uma ampla variedade de potencias dispersores dessa palmeira. A IC possui 53ha e tem como situação particular o grande número de quatis (Nasua nasua), introduzidos na década de 40. O trabalho teve como objetivos: conhecer os padrões fenológicos de S. romanzoffiana nas duas áreas, verificar como as diferenças na composição e riqueza de fauna entre os locais afetam a dispersão e a predação de sementes e analisar a produção e a predação pré-dispersão das sementes no PMLP. Como observação secundária, o trabalho relata o uso de sementes ocas como locais de nidificação de formigas. Observou-se que pelo menos 25 sementes foram ocupadas por ninhos de formigas, sendo registrado um total de onze espécies. Apesar das sementes serem abundantes no ambiente, a taxa de ocupação foi baixa, provavelmente devido ao tamanho que limita a ocupação somente às menores espécies de formigas. A floração de S. romanzoffiana ocorreu de setembro a fevereiro na IC e de novembro a fevereiro no PMLP. Os frutos estiveram presentes o ano inteiro nas duas áreas, sendo que a oferta de frutos maduros se deu por no mínimo oito meses. Isso demonstra que durante todo ano existe uma oferta de frutos para os predadores e dispersores de sementes nas infrutescências e no solo. A dispersão (remoção) e a predação de sementes se mantiveram com altas taxas nas duas áreas e não foram afetadas pelas diferenças entre a composição e riqueza de fauna dos locais de estudo. Foi encontrada uma variedade de frugívoros consumidores dos frutos no PMLP, e, pelo menos, cinco são potencias dispersores. Na IC, apesar da menor diversidade de frugívoros presentes, a dispersão das sementes de S. romanzoffiana parece estar sendo favorecida pela abundância de quatis. Quanto à estrutura da população, a maior diferença encontrada foi no número de adultos reprodutivos, superior na IC. Essa diferença pode ser atribuída as maiores condições de borda na IC, uma vez que o desenvolvimento até a fase adulta parece ser favorecido por melhores condições de luz. A maior pressão envolvendo a espécie é a predação de sementes na fase de pré-dispersão, onde mais da metade das sementes podem ser consumidas por larvas de um Curculionidae específico, Revena rubiginosa. No PMLP, a produção de sementes é alta e sofre variações em nível individual e populacional entre anos reprodutivos. Uma vez que ocorre alta densidade de plântulas e sementes viáveis nas áreas, anos com alta produção de sementes parecem ser suficiente para saciar a população dos predadores específicos e permite que algumas sementes escapem e possam ser dispersas, encontrando condições favoráveis para a germinação e o estabelecimento.

Para tanto, partimos da hip?tese de que ele se constituiu em um privilegiado ve?culo para a interven??o educativa da sociedade caicoense, no per?odo inicial do Regime Republicano, reconhecido pelas intensas movimenta??es sociais. Para a execu??o do proposto, optou-se pela base te?rica estabelecida pelo paradigma historiogr?fico instaurado pela Escola dos Annales, que permitiu a conjuga??o entre os pressupostos conceituais de Norbert Elias, Roger Chartier e Michel Foucault, com vistas a abranger um estudo da configura??o social em que se formou a pr?tica discursiva disposta no jornal em estudo, tendo como linha investigativa as proposi??es da hist?ria cultural. Quanto ? compreens?o e tratamento metodol?gico do discurso, contido como pr?tica materialmente constru?da, aderiu-se ao enfoque anal?tico apresentado nas postula??es foucaultianas, nas quais s?o considerados os conjuntos das forma??es enunciativas, esparsas em fontes e documentos que, coligidas, formam grupos de enunciados pertinentes ? descri??o de um mesmo objeto. A principal fonte de pesquisa foi a cole??o dos n?meros do Jornal das Mo?as, editados, apenas, em 1926, parte dela composta por pe?as documentais originais, a que tivemos acesso nos locais de pesquisa durante o esfor?o investigativo, como o Acervo da Biblioteca Central Zila Mamede, o Laborat?rio de Documenta??o Hist?rica do Centro de Ensino Superior do Serid?, da Universidade Federal do Rio Grande do Norte. Desse modo, constatou-se que a pr?tica discursiva que se examinou, na constitui??o desta disserta??o, foi um meio para a compreens?o das representa??es advindas do momento hist?rico e social das primeiras d?cadas do s?culo XX, quando se tornam evidentes as articula??es discursivas de uma pr?tica pedag?gica como dispositivos higienistas

Resumo: Foram avaliados, clínica e radiograficamente, as reações de quatro diferentes superfícies de implante frente ao desenvolvimento e progressão da peri-implantite: Ticp: titânio comercialmente puro; TPS: titânio revestido com plasma spray de titânio; HA: hidroxiapatita; Ost. Superfícies tratadas com ácidos. Para tanto, foram utilizados seis cães, cujos pré-molares inferiores e superiores foram extraídos. Decorridos 90 dias, os implantes foram aleatoriamente colocados, e iniciou-se o controle químico e mecânico do biofilme bacteriano; após o período de osseointegração (90 dias) foram colocados os conectores, e após 45 dias da colocação dos conectores, iniciou-se a indução da peri-implantite por meio de ligaduras de fio de algodão (suspensão do controle do biofilme bacteriano), e os primeiros exames clínicos (profundidade de sondagem, sangramento à sondagem, índices de placa e sangramento, e mobilidade) e radiográficos (perda óssea) foram realizados. Esses parâmetros foram novamente avaliados após 20, 40 e 60 dias, quando da troca das lidaguras. A análise dos resultados não demonstrou diferença significante entre as superfícies, em nenhum dos parâmetros analisados, com exceção da mobilidade (avaliada pelo PeriotestÒ) e perda óssea, que foram menores nos implantes TPS. Concluiu-se que as superfícies apresentam comportamento semelhante durante a indução da peri-implantite, com exceção no parâmetros mobilidade e perda óssea, que apresentaram os implantes TPS com comportamento superior. / Abstract: The reactions of four different implant surfaces were evaluated in regard to the development and progression of peri-implantitis: titanium commercially pure (Ticp), titanium plasma spray (TPS) hidroxiapatite coated (HA) and acid attached surfaces (Ost). Six dogs had their premolars extracted. After 90 days, the implants were ramdonly placed and the dogs receive soft diet, chemical and mechanical plaque control; after the osseointegration period (90 days), the healing abutments were placed. After the healing period (45 days), the plaque control was suspended, and cotton ligatures were installed when the first clinical (probing depth, bleeding on probing, plaque index, bleeding index, and mobility) and radiographic (bone loss) exams were taken. These parameters were re-exanimate after 20, 40 and 60 days, when the ligatures were changed. The results did not show significant differences between the surfaces in any parameter observed except for the mobility (evaluated with PeriotestÒ), and bone loss. These two parameters had the TPS surface with the lower rates. It was conclude that the surfaces show similar behavior during the induction of peri-implantitis, except for the mobility and bone loss parameters witch the TPS implants had better behavior. / Orientador: Ricardo Samih Georges Abi Rached / Coorientador: Elcio Marcantonio Junior / Banca: Rosemary Adriana Chiérice Marcantonio / Banca: Luiz Antonio Pugliesi Alves de Lima / Mestre

Por meio delas, os usu?rios podem disseminar seus estudos, assim como desenvolver novas pesquisas. Um dos sistemas utilizados para cria??o e gest?o de peri?dicos eletr?nicos ? o Sistema Eletr?nico de Editora??o de Revistas (SEER), utilizado na constru??o de portais de peri?dicos, assim como na cria??o de revistas isoladamente. Nesse sentido, acredita-se que os sistemas de gest?o e cria??o de revistas cient?ficas eletr?nicas devem ser desenvolvidos (interna e externamente) de acordo com as necessidades dos seus usu?rios. No caso do desenvolvimento interno, alguns desses processos se referem ao cadastro de autor e ? submiss?o de artigos, que, por sua vez, s?o tarefas relevantes no processo editorial. Assim, o trabalho proposto, de tem?tica Usabilidade de peri?dicos cient?ficos, objetiva analisar a usabilidade do processo de cadastro de autor e de submiss?o de artigos no SEER por meio da revista BiblioCanto, que integra o Portal de Peri?dicos Eletr?nicos da Universidade Federal do Rio Grande do Norte (UFRN). Para a efetiva??o da pesquisa, foram utilizadas duas t?cnicas de avalia??o: o Teste de Usabilidade e a Avalia??o Cooperativa, com um total de vinte participantes, divididos em quatro categorias. Para validar os instrumentos da pesquisa (o question?rio pr?-sess?o e o Questionnaire of User Interaction Satisfaction), foram realizados dois testes piloto antes da realiza??o da avalia??o em definitivo. Ap?s a execu??o do Teste de Usabilidade e Avalia??o Cooperativa em definitivo, os resultados apontaram que os dois processos analisados (cadastro de autor e submiss?o de artigos) necessitam de melhorias. Em se tratando do processo de cadastro, destacam-se as seguintes necessidades: sinaliza??o do ambiente de realiza??o de cadastro; descri??o e exclus?o de informa??es solicitadas no formul?rio para cadastramento. No processo de submiss?o de artigos, enfatizam-se melhorias dos aspectos: in?cio dos passos para submiss?o, sinaliza??o de campos obrigat?rios, descri??o concisa das etapas, minimiza??o e revis?o das etapas. Para Por fim, acredita-se que de uma forma geral o SEER atende parcialmente ?s necessidades dos seus usu?rios no tocante ? usabilidade do referido software. / The electronic journals correspond publishing channels and dissemination of scientific information. Through them, users can spread their studies as well as developing new researches. One of the systems used for creation and e-journals management is the Electronic System for Journal Publishing (SEER), used in the construction of periodic portals, as well as the creation of magazines in isolation. In this purport, it is believed that the management systems and creation of e-journals should be developed (internally and externally) according to the needs of its users. In the case of internal development, some of these processes refer to the copyright registration and submission of articles, which, in turn, are relevant tasks in the editorial process. Thus, the proposed study, thematic Usability of scientific journals, aims to analyze the usability of the copyright registration process and submission of articles in the Electronic System for Journal Publishing through BiblioCanto magazine, part of the Electronic Journals Portal of the Federal University of Rio Grande do Norte (UFRN). For the realization of the research, two valuation techniques were used: the Usability Test with a total of twenty participants and the Cooperative Evaluation, with the same number of participants separated in four categories considered target audience of that magazine, namely: undergraduate students, graduate students, teachers and librarians. The results indicated that the two analyzed processes (copyright registration and submission of articles) need improvement. In the case of the registration process, the following needs are: signalizing of the conducting registration ambient; description and exclusion of requested information on the registration form. In the process of article submission, it is emphasized improvement of aspects: the early steps to submission, signaling of required fields, concise description of the steps, minimization and review of the steps. To this end, it is believed that in general idea the SEER partially meets the needs of its users regarding the usability of such software.
