Previous issue date: 2015-03-19 / Nenhuma / Este dissertação teve como objetivo foi avaliar e comparar a comunicação de cônjuges que têm filhos em distintas etapas do ciclo vital familiar, com os diferentes níveis de funcionalidade definidos através da coesão, da adaptabilidade e do ajustamento conjugal. Realizou-se um estudo quantitativo com delineamento descritivo e comparativo. A amostra foi constituída por 286 sujeitos casados ou em união estável com filhos de 0 a 18 anos. Os participantes responderam individualmente ao protocolo on line constituído por um questionário sócio demográfico, a Escala Marital Inventory Communication, a Escala Dutch Marital Satisfaction and Communication Questionnaire, Escala de Avaliação da Coesão e Adaptabilidade Familiar, e a Escala de Ajustamento Diádico. Esta dissertação está organizada na forma de dois artigos empíricos: “Comunicação conjugal em diferentes etapas do ciclo de Vida e “Padrões de Comunicação conjugal em homens e mulheres.” Os resultados encontrados indicam que a conjugalidade se sobrepõe a parentalidade, visto que a idade dos filhos não teve interferência na comunicação, e também pontuam que homens e mulheres se comunicam de formas iguais, mas cada um com sua especificidade. Estes achados apontam que as variáveis estudadas têm grande importância para o estudo das relações conjugais e para o entendimento deste fenômeno. / The aim of this dissertation is to evaluate communication (communication levels and styles) between spouses with different levels of functionality (adjustment, cohesion and adaptability) in different stages of marital life cycle (toddlers, school age, teenagers). A quantitative study with descriptive and comparative design was held. The sample was composed by 286 married people or in a common law marriage with children aged between 0 and 18 years old. The participants answered the online protocole individually composed by a socio-demographic questionnaire, the Marital Inventory Communication Scale, Dutch Marital Satisfaction Scale, Communication Questionnaire, Family Adaptability and Cohesion Evaluation Scale, Dyadic Adjustment Scale. This dissertation is organized in a frame of two empirical articles: “Marital Communication in different stages of life cycle” and “Positive and Negative Communication: Differences between men and women”. The found findings point that the studied variables have great importance to the study of conjugal relationships and for the clinical understanding of this phenomenon.

The Post-frontier: Land use and social change in the Brazilian Amazon (1992 - 2002)Summers, Percy M. 21 July 2008 (has links)
Deforestation of tropical forests is one of the most pressing environmental problems of the twenty-first century, leading to the loss of environmental services such as climate regulation and biodiversity. The expansion of the agricultural frontier by small landholder farmers continues to be one of the major drivers of land use change in the Amazon region. Much of the recent research in the Brazilian Amazon has been focused on modeling their behavior in order to prescribe policies that can curb current deforestation rates and promote more sustainable land use practices. The availability of more sophisticated remote sensing and economic modeling tools has led to the proliferation of agricultural household level models that attempt to explain land use change processes at the farm level. This dissertation tests the household life cycle theory in one of the oldest colonization fronts in the Brazilian Amazon: Rondônia, now a post-frontier.
The study examines household and farm level changes over time for specific aspects of the frontier process that can be tested using the household life cycle theory. This study introduces important additions to the life cycle theory in order to consider the more dynamic and complex set of factors that characterize modern frontier processes. Specifically the study examines: (1) property fragmentation and expansion processes, (2) property ownership, turnover and change, and (3) land use change processes at the property level. These are linked to changes in the social and economic features of the smallholder farmer as it moves along its life cycle. The central hypothesis is that these changes in property and land use dynamics can be explained by the corresponding changes in the life cycle of the household as the frontier evolves over time into a post-frontier.
It was found that the household life cycle theory did not adequately explain land use change processes over time. As the frontier evolved into the modern post-frontier, the labor and drudgery constraints associated with the initial frontier processes, as exemplified in the household life cycle theory, became less relevant. The Sauerian concept of cultural successions and the concept of scale from hierarchical ecology are used in order to explain the apparent inconsistencies found between the household life cycle theory and land use change processes over time and at different scales of analysis. The household life cycle theory is a useful theoretical framework from which to examine the effects of household level factors on land use; however, this must be embedded within concepts of time and scale that determine their differentiated impact and behavior.
Existing plans to expand road infrastructure into the Amazon region will open-up previously inaccessible rainforest regions to agricultural frontier expansion at a scale unprecedented since the mid-eighties. Findings from this study reveal that policies based on household life cycle postulates will have limited impacts in reducing deforestation rates and promoting sustainable land use practices. Appropriate accounting of the social and environmental costs of future infrastructure development projects should consider associated frontier agricultural expansion costs to discourage further deforestation. / Ph.
