This research contributes to an understanding of the relationship between climate change, economic impacts and migration. We model the long-term relationship (up to 45 years of projection) between demographic dynamics—particularly migration—driven by changes in the performance of the economy due to climate changes in the Northeast region of Brazil. The region is of particular relevance to the study of climate change impacts given its large human population (28% of Brazil’s population) and high levels of impoverishment, having an extensive semi-dry area which will be severely impacted by growing temperatures. Ultimately, the integrated model generates state- and municipal-level migration scenarios based on climate change impacts on the primary economic sectors and their articulations with other sectors. Results suggest that the predicted climate changes will impact severely the agriculture sector in the region, acting as a potential migration push factor to other regions in the country. Finally, we discuss how the increased vulnerability of some groups, particularly migrants, can be factored into Brazilian public policy and planning.  相似文献

Same parliaments, to form a committee of size $q$ , use a voting process like the following: every parliamentary member votes for one out of a fixed set of candidates, and those $q$ candidates receiving more votes are elected for the committee. Assuming total discipline of vote, this is a game form in which players are the parliamentary groups. We investigate, according to some natural hypotheses about preferences, the likely distribution of the members of this committee. The main results are: (a) when fractional votes are allowed, there is a complete agreement between the distribution among the groups of the elected candidates that are outcomes of a Nash equilibrium and the distribution that, according to the size of the groups, would compute the Jefferson-d’Hondt allocation rule, and (b) when fractional votes are not allowed, there is a near agreement for a majority of situations.  相似文献

If voters vote strategically, is it useful to offer them the possibility of expressing nuanced opinions, or would they always overstate the intensity of their preferences? For additive voting rules, say that a ballot is extremal if it is neither abstention-like nor can be expressed as a mixture of the available ballots. We give a sufficient condition for strategic equivalence: if two rules share the same set of extremal ballots (up to an homothetic transformation), they are strategically equivalent in large elections. This condition is also necessary for the strategic equivalence of positional rules. These results do not hold for small electorates.  相似文献

In the same way that many aspects of gender cannot be understood aside from their relationship to race, class, culture, nationality and/or sexuality, the interactions between gender and aging constitute an interesting field for academic research, without which we cannot gain full insight into the complex and multi-faceted nature of gender studies. Although the American writer and Columbia professor Carolyn Gold Heilbrun (1926-2003) is more widely known for her best-selling mystery novels, published under the pseudonym of Amanda Cross, she also authored remarkable pieces of non-fiction in which she asserted her long-standing commitment to feminism, while she also challenged established notions on women and aging and advocated for a reassessment of those negative views. To my mind, the Kate Fansler novels became an instrument to reach a massive audience of female readers who might not have read her non-fiction, but who were perhaps finding it difficult to reach fulfillment as women under patriarchy, especially upon reaching middle age. Taking her essays in feminism and literary criticism as a basis and her later fiction as substantiation to my argument, this paper will try to reveal the ways in which Heilbrun's seemingly more superficial and much more commercial mystery novels as Amanda Cross were used a catalyst that informed her feminist principles while vindicating the need to rethink about issues concerning literary representations of mature women and cultural stereotypes about motherhood.  相似文献

This paper examines family interactions between mothers and children in single‐parent‐by‐choice (SPBC) families in Spain. The data is part of a larger multi‐sited ethnographic study focused on emergent family structures that examined families formed by women who began their family projects through adoption or assisted reproduction. Single‐mothers‐by‐choice formulate various socialization goals that are tied to the complexities of their non‐conventional family project. These goals are also realized in daily conversation, particularly when families talk about future events in their lives. Our findings expand existing family language socialization research in Western contexts, which has primarily focused on conventional two‐parent families, and invite developing a stronger dialogue between family language socialization research and current debates on changing kinship structures in post‐industrial societies. Este trabajo examina interacciones entre madres e hijos/as en familias de madres solteras por elección (MSPE) en España. Los datos provienen de una investigación etnográfica multi‐lugar más amplia centrada en modelo familiares emergentes que estudió a familias formadas por mujeres solas que han comenzado su proyecto familiar a través de la reproducción asistida o la adopción. La madres solteras por elección formulan varias metas de socialización que están ligadas a las complejidades y demandas de su proyecto familiar no convencional. Estos objetivos también se plasman en conversaciones cotidianas, especialmente cuando las familias hablan sobre eventos futuros en su vidas. Nuestros resultados amplían la investigación sobre socialización lingüística familiar en contextos occidentales, que se ha centrado principalmente en familias bi‐parentales convencionales, e invitan a desarrollar un diálogo más fructífero entre la investigación sobre socialización lingüística familiar y los debates actuales en torno a cambios en los patrones de parentesco en sociedades post‐industriales.

This paper presents an assessment with simulated activities with the aim of analyzing the perception of ease / difficulty of the use of faucets (taps) handles by 180 Brazilian adults. Five different handles faucets were activated for subsequent collection of perceptual data. The procedures were based on main recommendations for biomedical ethics and human research. The results indicate that handles with levers are significantly (p ≤ 0.05) easier to use. The most difficult are characterized by not having support points for the rotation (levers) or more points of pressure concentration in the hand.  相似文献

This work is based on the ergonomic approach and the principles of universal design, with the aim of establishing the cognitive design features that interfaces must comply, for older adults achieve a good performance during their interaction with technological aids. Describes the analysis of exploratory experiences with a group of 17 older adults was aimed first to establish the main barriers to implementation that arise during these activities, and secondly to set the variables to be addressed and the procedure required to develop depth study, where the relationship establish between the quality of the stimuli and the level of performance achieved in the implementation of older adults with interfaces, observing each of the cognitive functions that promote independence, attention, motivation, memory these processes. The study in depth, looking for describe gaps and mismatches encountered during execution, which hamper the harmonious interaction processes through participatory methodological approach that allows to specify requirements for the creation of stimulating interfaces for cognitive skills and committed with the levels of autonomy of the elderly.  相似文献

This article is the result of a case study on ergonomic work analysis carried out in an urban bus company located in Ilha do Governador, Rio de Janeiro. The methodology used in this work follows the French-tradition Ergonomic Analysis of the Work (EWA) combined with the best tradition from anglo-saxon ergonomic work analysis. The situated diagnosis was performed to provide relevant information about the work conditions of a bus driver.  相似文献

The problems related to the means of transport in urban Brazilians have been getting worse over the years. The increase of the fleet, to the detriment of the adequacy and extent of the road network of cities contributes to this fact. This paper presents a profile of users of cycling in the city of Juiz de Fora, and thus contributes to the study of sustainable urban mobility, providing researchers with information that can guide the search for the encouragement of the use of means of transport to meet environmental needs urban centers that contributes to social equity.  相似文献

This article presents the steps of transforming the material and organizational aspects in the work environment, beyond the social order for the proper development of activities in the Household Distribution Center, the Postmen Motorcyclists. The demand was made by managers from the accident records, establishing the need to identify the working conditions of postmen motorcyclists, regarding motorcycle accidents occurring on public roads. Method: Based on the characteristics of the steps required by the methodology, was necessary to realize internal and external observations, with the aim of identifying the dynamics of the accident and the collective dimensions of activity which requires a strategy for monitoring the work on the street.  相似文献
