Pesquisa do Estado do Rio Grande do Sul - FAPERGS / This dissertation presents two essays on the relationship between technical change and the natural environment. In the first essay, we discuss the view of technical progress to four representatives of Classical Political Economy: William Petty, Adam Smith, David Ricardo and Karl Marx. This essay analyzes the form they approach the technical progress, characterized by the increasing adoption of machinery in the production process, adding up the view of each author regarding land and natural resources in the growth of nations. While the technical progress concept evolves from the first to the last author, nature?s view is distinct. Petty and Marx define the natural environment as a part of a natural law and as a part of human essence, respectively. Smith and Ricardo reduce natural environment to an input, making it the main economic growth limiter for the latter. In the second essay, we analyze the technical progress and the production of good and bad outputs in Brazilian economy in the 1970-2008 period. We adopt a study system of production and technical progress based on a classical-Marxian perspective, in which the work, capital and energy input combination generates a good output, the Gross Domestic Product (GDP), and a bad output, carbon dioxide (CO2) emissions. We divide Brazilian economic growth in four phases, according to the development strategy adopted in each period: 1970-1980, 1980-1989, 1989-2003 and 2003-2008. The predominant pattern of technical progress was Marx-biased and energy-saving. In GDP growth years, the bad output also increased. / Esta disserta??o apresenta dois ensaios sobre a rela??o entre progresso t?cnico e meio ambiente. No primeiro ensaio, discute-se a vis?o de progresso t?cnico e natureza para quatro representantes da Economia Pol?tica Cl?ssica: William Petty, Adam Smith, David Ricardo e Karl Marx. O objetivo deste ensaio ? analisar a forma como abordam o progresso t?cnico, caracterizado pela crescente ado??o de maquinaria no processo produtivo, somado ? vis?o de cada autor a respeito da terra e dos recursos naturais no crescimento das na??es. Enquanto o conceito de progresso t?cnico evoluiu do primeiro ao ?ltimo autor, a vis?o da natureza ? distinta. Petty e Marx definem o meio ambiente em uma ordem natural e como parte da ess?ncia do ser humano, respectivamente. Smith e Ricardo reduzem o meio ambiente a um insumo, tornando-se o principal limitador do crescimento para este ?ltimo. No segundo ensaio, analisa-se o progresso t?cnico e a produ??o de bons e maus produtos na economia brasileira no per?odo 1970-2008. Adota-se um sistema de estudo de produ??o e progresso t?cnico baseado em uma perspectiva cl?ssico-marxiana, em que a combina??o dos insumos trabalho, capital e energia geram um bem, o Produto Interno Bruto (PIB), e um mal, as emiss?es de di?xido de carbono (CO2). Divide-se o crescimento econ?mico brasileiro em quatro fases, de acordo com a estrat?gia de desenvolvimento adotada em cada ?poca: 1970-1980, 1980-1989, 1989-2003 e 2003-2008. O padr?o de progresso t?cnico predominante foi Marx-viesado e poupador de energia. Nos anos de crescimento do PIB, o mau produto tamb?m aumentou.

In the case of bees, such changes may have more drastic impacts, because these insects are important pollinators in natural and agricultural environments. Based on this, this study analyzed the effect of climate change on the geographic distribution of seven species of Plebeia of ecological and economic importance in the subtropical zone of South America in the current and future scenarios. For that it were identified climate variables that will most likely affect their distribution. The studied species were P. molesta, P. droryana, P. emerina, P. nigriceps, P. saiqui, P. remota and P. wittmanni. The species distribution was modeled using the variables temperature, rainfall and altitude. To describe future climate it were used bioclimatic variables for the year 2070 under the RCP4.5 scenario from Intergovernmental Panel on Climate Change (IPCC). The analysis of data revealed that P. nigriceps and P. saiqui might have the largest reduction in area in the future (> 60%). On the other hand, P. emerina might have a moderate increase in the occurrence area (2.5%), whereas P. wittmanni, a significant increase (55%). Most of the studied species is strongly associated with the Atlantic Forest biome, and P. droryana and P. remota may be even more restricted to this biome. The estimated temperature change for the future scenario could affect the diapause species of Plebeia and the expected increase in rainfall may negatively influence the flight activity. If the changes in the habitat of the species are confirmed, the pollination service of native plants and crops may be affected. / Os cen?rios futuros com mudan?as clim?ticas podem levar a altera??es na distribui??o geogr?fica, ecologia e comportamento das esp?cies. No caso espec?fico das abelhas, as altera??es poder?o ter consequ?ncias mais dr?sticas, pois esses insetos s?o importantes polinizadores em ambientes naturais e agr?colas. Baseado nisso, este trabalho analisou o efeito das altera??es clim?ticas na distribui??o geogr?fica de sete esp?cies de Plebeia de import?ncia ecol?gica e econ?mica na zona subtropical da Am?rica do Sul nos cen?rios atual e futuro. Para isso foram identificadas as vari?veis clim?ticas que mais provavelmente podem afetar a sua distribui??o. As esp?cies estudadas foram P. molesta, P. droryana, P. emerina, P. nigriceps, P. saiqui, P. remota e P. wittmanni. A distribui??o das esp?cies foi modelada utilizando as vari?veis de temperatura, precipita??o e altitude. Para descrever o clima futuro foram utilizadas as vari?veis bioclim?ticas para o ano de 2070, sob o cen?rio RCP4.5 definido pelo Intergovernmental Panel on Climate Change (IPCC). A an?lise dos dados revelou que P. nigriceps e P. saiqui poder?o ter as maiores redu??es de ?rea no futuro (>60%). Por outro lado, P. emerina poder? ter um aumento moderado na ?rea de ocorr?ncia (2,5%), enquanto que para P. wittmanni, estima-se um aumento expressivo (55%). A maioria das esp?cies estudadas tem grande rela??o com o bioma da Mata Atl?ntica, sendo que P. droryana e P. remota poder?o ficar ainda mais restritas a esse bioma. A estimativa de mudan?a da temperatura para o cen?rio futuro poder? afetar a diapausa reprodutiva das esp?cies de Plebeia e o aumento estimado da precipita??o poder? influenciar negativamente a atividade de voo. Caso as altera??es no habitat das esp?cies se confirmem, o servi?o de poliniza??o de plantas nativas e culturas agr?colas poder? ser afetado.

Dependente de condi??es clim?ticas ideais, melhores desempenhos para essa atividade s?o observados em regi?es de latitudes baixas, caracterizadas por temperaturas elevadas e ventos constantes, al?m de baixo volume de precipita??o. Assim, sendo a produ??o de sal marinho dependente de condi??es clim?ticas, analisar, estatisticamente, as influ?ncias que o clima, suas variabilidades e mudan?as exercem sobre a produ??o desse mineral, foi o objetivo principal dessa tese. Para isso, a tese foi dividida em dois artigos. No artigo primeiro, o objetivo principal foi analisar a correla??o entre essas vari?veis clim?ticas e a produ??o de sal marinho, bem como estimar a intensidade com que varia o volume desse mineral em consequ?ncias de mudan?as clim?ticas, no munic?pio de Macau-RN. Os resultados mostraram correla??es positivas entre o volume produzido de sal marinho com a temperatura, horas de insola??o, evapora??o e velocidade do vento e, correla??es negativas com a precipita??o e umidade relativa. Em rela??o ?s mudan?as clim?ticas, constatou-se aumento no volume de sal marinho pelos quatro cen?rios de mudan?as clim?ticas previstas pelo IPCC no munic?pio de Macau-RN, sendo que o melhor cen?rio para a ind?stria de sal por evapora??o solar ? o RCP8.5. No artigo dois, o objetivo principal foi estimar o impacto econ?mico das mudan?as clim?ticas sobre a produ??o de sal marinho. Os resultados mostraram que as mudan?as clim?ticas poder?o impactar positivamente as receitas de vendas das ind?strias de sal marino no RN, em qualquer cen?rio de mudan?as clim?ticas, variando o aumento m?dio anual sobre essas receitas de vendas de 9,1227% pelo cen?rio RCP2.6 a 16,5350% pelo cen?rio RCP8.5, sendo poss?vel afirmar que as mudan?as clim?ticas projetadas pelo IPCC ir?o impactar positivamente a produ??o de sal marinho. / The production of sea salt in Rio Grande do Norte has contributed significantly to the social and economic development of the State, creating jobs, increasing incomes and adding to the public revenue through taxes. Climatic conditions that favor this activity are observed in regions of low latitude characterized by high temperatures and constant winds, as well as low precipitation. Thus, as the production of sea salt depends on climate conditions, the aim of this thesis is to analyze, statistically, how the influences of the climate variability and changes affect the production of this mineral. To this end, the thesis comprises two articles. In the first article, the main objective was to analyze the correlation between these climatic variables and the production of sea salt, as well as estimate the intensity with which the volume of this mineral varies as a result of climate change in the city of Macau, RN. The results show positive correlations between the volume of sea salt production and the temperature, hours of sunlight, evaporation and wind speed, and negative correlations with precipitation and relative humidity. In relation to climate changes, findings showed an increase in the volume of sea salt in four scenarios of climate change, which were presented by the IPCC, in the city of Macau, RN. Results showed that the best scenario for the salt industry proved to be solar evaporation at a rate of RCP8.5. In the second article, the main objective was to gauge the economic impact of climate change on sea salt production. The results showed that climate changes will generate a positive impact on the income from sales in the sea salt industry in RN, in all of the climate change scenarios. The average annual increase in income from sales in this industry is estimated at varying from 9.12% in scenario RCP2.6 to 16.53% in scenario RCP8.5, making it possible to affirm that the sea salt industry in RN will benefit from climate changes.

O termo emancipa??o tem sido gerador de discord?ncias e pol?micas, tendo-se em conta o fato de que a mulher, mesmo havendo ingressado no mercado de trabalho, continua a exercer os pap?is socialmente impostos ? o de m?e, esposa e dona de casa. Em paralelo, as revistas femininas, em especial a revista Claudia, assumiram o prop?sito de orientar as mulheres no desempenho de suas muitas fun??es: como educar os filhos, como cuidar do lar, como agradar o c?njuge, e at? como ter sucesso na carreira profissional. Circunscrita nesse contexto, esta tese visa revelar as perman?ncias e as rupturas que se manifestam nos discursos femininos registrados na fanpage Claudia online, testemunhando como os pap?is sociais e as rela??es de poder influenciam na (trans)forma??o das identidades femininas. Em fun??o desse alcance, buscou-se uma sustenta??o te?rica nos postulados da An?lise Cr?tica do Discurso (ACD); mais especificamente, na Abordagem Sociol?gica e Comunicacional do Discurso (ASCD) ?, que, por sua vez, est? sendo desenvolvida na Universidade Federal do Rio Grande do Norte, em concomit?ncia com a Universidade Federal de Sergipe, sob a coordena??o da professora Dr.? Cleide Em?lia Faye Pedrosa (PEDROSA, 2012). Tamb?m se fez ancoragem, neste percurso investigativo, em saberes da Lingu?stica Sist?mico-Funcional (LSF); especialmente, no que concerne ao Sistema de Avaliatividade; na Sociologia para Mudan?a Social e nos Estudos Culturais. A ancoragem metodol?gica firma-se no paradigma qualitativo-interpretativista (MOITA LOPES, 2006), circunscrito ?s Ci?ncias Humanas e Sociais, com foco na Lingu?stica Aplicada (LA). O corpus comp?e-se de vinte e quatro postagens, divididas em seis tem?ticas recorrentes na fanpage Claudia online. Os resultados indicam que a fanpage Claudia online discute, de fato, os pap?is que as mulheres exercem em nosso meio social. Observa-se, ainda, que alguns desses pap?is foram solidificados devido aos par?metros conservadores da sociedade, perpetuando-se por muitas gera??es e sendo naturalizados ao sexo feminino. A constata??o ?, pois, a de que h? perman?ncia dos pap?is impostos, e de que, na modernidade recente, as mulheres passaram a exercer outros tantos pap?is, merecendo destacar o fato de que, hoje, a mulher trabalha fora, investe na forma??o acad?mica, frequenta academia diariamente, dirige autom?vel, participa das reuni?es escolares dos filhos, vai ao sal?o de beleza, administra o pr?prio sal?rio, delega fun??es ? secret?ria dom?stica; enfim, executa muitas tarefas concomitantemente, configurando-se, assim, o ac?mulo de fun??es exercidas pelas mulheres, o que justifica a atribui??o do r?tulo de ?mulher maravilha?, e leva ? ruptura nos padr?es e na execu??o dos pap?is femininos. / The roles played by women in late modernity (MOITA LOPES, 2013) encouraged the interest of a great number of national and international researchers. The term emancipating in anyway has been of disagreement and controversy, taking into account the fact that the woman, even though has conquered the labor market, continues to play the roles imposed by society ? of mother, wife and of housewife. At the same time, women's magazines, mainly Claudia magazine, have assumed the purpose to guide women in the performance of their multiple functions: how to educate their children, how to take care of their home, how to please their spouse, and even how to succeed in their professional careers. Circumscribed in this context, this thesis aims at investigating the permanence and the ruptures that are expressed in women's speeches posted in the fan page of Claudia magazine online, testifying how social roles and power relations influence the (trans)formation of female identities. Due to this scope, this research is based on the theoretical framework postulated by the Critical Discourse Analysis (CDA); specifically, in the Sociological and Communication of Discourse Approaches (ASCD) ? that is being developed at the Universidade Federal do Rio Grande do Norte, in partnership with the Universidade Federal de Sergipe, coordinated by the PhD Profesor Cleide Emilia Faye Pedrosa (Pedrosa, 2012). This study is also based, during the investigation, on knowledge of Systemic Functional Linguistics (SFL); especially regarding to the Appraisal System; in Sociology for Social Change and Cultural Studies. Methodologically, the research is anchored in the qualitative-interpretative paradigm (MOITA LOPES, 2006), circumscribed to Human and Social Sciences, focusing on Applied Linguistics (LA). The data of this research is made up of twenty-four postings, divided into six recurring themes, in the fan page of Claudia Magazine online. The results show that the fan page Claudia online, in fact, discusses the roles that women play in our social context. It is also observed that some of these roles were solidified due to conservative parameters of society, perpetuating itself for many generations and being naturalized to female gender. The finding is, therefore, that there is a permanence of the imposed roles, and that, in late modernity, women have come to play so many other roles, deserving to highlight the fact that nowadays the woman works outside, invests in academic education, visits regularly the gym, drives a car, attends the school meetings of their children, frequents beauty salon, manages their own incomes, delegates household jobs to the housemaid; finally, she carries out many tasks simultaneously, establishing thus the accumulation of positions held by women, which justifies the label attributes of "wonder woman", and leads to disruption in patterns and in the implementation of women's roles.

Entender os padr?es clim?ticos (circula??o da atmosfera, precipita??o, temperatura) ? essencial para a previs?o de extremos clim?ticos, mas o grande desafio ? analisar como esses eventos extremos atuam em nossa sociedade e procurar meios de diminuir o seu impacto. Um conceito bastante utilizando em ci?ncias humanas e sociais para compreender esses impactos e o processo de adapta??o da sociedade ? o da vulnerabilidade. O objetivo deste trabalho ? desenvolver e aplicar uma metodologia multi escala para avaliar e quantificar a vulnerabilidade do Nordeste Brasileiro a extremos clim?ticos, desenvolvendo uma metodologia que combina aspectos de vulnerabilidade a seca, bem como utilizar indicadores socioecon?micos e clim?ticos para avaliar a exposi??o, capacidade de adapta??o e a sensibilidade das microrregi?es geogr?ficas desta ?rea. A avalia??o da susceptibilidade ou grau de exposi??o ao risco regional foi utilizando o SPI (Standardized Precipitation Index) atrav?s do grau de magnitude de seca (MD), os ?ndices de chuva como o PCD (Precipitation Concentration Degree) e PCP (Precipitation Concentration Period) ajudaram a caracterizar e climatologia regional. Esses ?ndices apresentaram resultados satisfat?rios no estudo piloto do Rio Grande do Norte para avaliar o grau de exposi??o ? seca. No que diz respeito a sensibilidade agr?cola/agropecu?ria a t?cnica estat?stica multivariada an?lise fatorial apresentou resultado aceit?vel para o modelo proposto usando dados referentes ao per?odo 1990- 1999 (P1). A aplica??o da an?lise de vulnerabilidade considerando tanto a capacidade adaptativa, quanto a incapacidade adaptativa apresentaram resultados praticamente similares com grande parte da regi?o com extrema vulnerabilidade localizada ao sul do estado da Bahia assim como parte da regi?o semi?rida apresenta grau de vulnerabilidade entre moderado e m?dio / The effects of climate change on human societies have become the focus of many researchers for their research. Understanding weather patterns (circulation of the atmosphere, precipitation, temperature) is essences for predicting extreme weather, but analyze how these extreme events act in our society and look for ways to reduce the impact caused by these events is the great challenge. Using a concept very in the humanities and social sciences to understand these impacts and the adaptation of the society's vulnerability. The objective of this work is to develop and apply a methodology for evaluating fining scale and quantify the vulnerability of the Brazilian Northeast to climatic extremes, developing a methodology that combines aspects of vulnerability to drought, as well as socioeconomic and climatic indicators used to assess exposure, ability to adaptation and the sensitivity of geographical microregions of the region. The assessment of the susceptibility or degree of exposure to risk is the regional using the SPI (Standardized Precipitation Index) by the degree of magnitude dried (MD), the rate of precipitation such as PCD (Precipitation Concentration Degree) and PCP (Precipitation Period Concentration) helped characterize and regional climatology, these indices showed satisfactory results in the pilot study of Rio Grande do Norte to assess the degree of exposure to drought. Regarding sensitivity agricultural / livestock multivariate statistical technique to factor analysis showed acceptable results for the proposed model using data for the period 1990-1999 (P1). The application of the analysis of vulnerability considering the adaptive capacity, as the adaptive disability have almost similar results with much of the region's vulnerability to extreme south of Bahia state as a part of the semiarid region has a degree of vulnerability among moderate and mean

Esse segmento atravessa um per?odo de transforma??es decorrentes do novo cen?rio concorrencial que se delineou com a chegada dos estabelecimentos das redes globais de com?rcio em Juazeiro do Norte. Frente ao papel desempenhado pelas unidades globais, os pequenos comerciantes varejistas do setor aliment?cio reafirmam novas facetas e revelam mudan?as e perman?ncias nas suas novas formas de atua??o. Nesse sentido, o trabalho objetivou analisar o com?rcio tradicional de g?nero aliment?cio do Crajubar, no contexto em que os hipermercados (Atacad?o Distribuidora, Maxxi Atacado, Hiper Bompre?o e Assa? Atacadista) pertencentes ?s grandes redes globais redefinem as rela??es estabelecidas entre pequenos comerciantes e os fornecedores locais. Debru?ou-se sobre a import?ncia da atividade comercial na din?mica hist?rico-espacial de Juazeiro do Norte, Crato e Barbalha e na atual configura??o espacial do aglomerado, real?ando as implica??es decorrentes e promovidas pelas redes globais de com?rcio. Realizou-se estudo bibliogr?fico, documental, historiogr?fico e pesquisa de campo, com aplica??o de entrevistas junto aos propriet?rios de estabelecimentos varejistas e aos principais ?rg?os envolvidos na din?mica comercial do Crajubar. A expans?o do com?rcio no aglomerado, principalmente, de Juazeiro do Norte, revela a import?ncia desse segmento que abrange uma escala mesorregional. A d?cada de 1990 constitui-se um marco do crescimento do n?mero de estabelecimentos varejistas e atacadistas no Crajubar e da consolida??o de Juazeiro do Norte como maior emp?rio comercial do aglomerado. Com a introdu??o das redes globais de com?rcio, na primeira d?cada do s?culo XXI, os mercadinhos, mercearias, bodegas e mercantis do Crajubar veem-se sob a necessidade de inovar-se, adotando estrat?gias de mudan?a para permanecer no mercado. O cen?rio atual do segmento comercial nas cidades de Crato, Juazeiro do Norte e Barbalha ? marcado pela resist?ncia dos pequenos varejistas diante das grandes grupos globais de com?rcio. Concomitantemente, as novas rela??es concorrenciais estabelecidas entre os pequenos varejistas, fornecedores locais e as grandes redes globais de com?rcio demonstram que, no bojo do avan?o t?cnico e da moderniza??o desse segmento econ?mico, formas antigas e novas de com?rcio convivem e se relacionam, (re)configurando e (re)definindo a din?mica espacial das cidades. / The present research contemplates the traditional commerce of foodstuff from Aglomerado Urbano Crajubar, located in the part south of Cear? State. This segment is going through a period of changes arising from the new competitive scenario that it was delineated with the arrival of establishments of global networks of commerce in Juazeiro do Norte. Front of the role played by global/worldwide unities, small retail merchants of food sector reaffirm new facets and reveal changes and permanence of new ways of acting. Therefore, the study aimed to analyse the traditional food commerce from Crajubar, in the context the hypermarkets(Atacad?o Distribuidora, Maxxi Atacado, Hiper Bompre?o and Assa? Atacadista) belonging to large global networks redefine the relation established between small merchants and local suppliers. It focused on the importance of commercial activity in the historical spatial dynamics of Juazeiro do Norte, Crato e Barbalha and in the current spatial configuration of urban aglomeration, highlighting the implications arising and promoted by global networks of trade. It was performed bibliographic study, documentary, historiografic and field studies through interviews with owners of retail establishments and to the main bodies involved in the commercial dynamics of Crajubar. The expansion of commerce in the aglomeration, mainly of Juazeiro do Norte, reveals the importance of this segment that encompasses a meso-reginal scale. The decade of 1990 constitutes a mark of the growth in the number of establishment retailer and wholesaler in Crajubar and of the consolidation of Juazeiro do Norte as the largest commercial emporium of aglomeration. With the introduce global networks of commerce, in the first decade 21st century, the small markets, groceries, bodegas and markets from Crajubar find themselves under the necessity of innovating, they are adopting change strategies to remain in the market. Present scenario of commercial segment in the cities of Crato, Juazeiro do Norte and Barbalha it is marked by resistance of small retailers in the face of the large global trading groups. Concomitantly, the new competitive relations established among small retailers, local suppliers and large global networks of trade demonstrate within technical advance and inside economic segment, Old and new forms of commerce coexist and relate to, (re)configuring and (re)defining spatial dynamics of the cities.

Muito al?m de tratar-se apenas de um aumento da temperatura mundial, as MCGs atingem atualmente a esfera das pol?ticas p?blicas, gerando interfer?ncias na vida dos seres humanos. ? importante ainda salientar que em se tratando das MCGs, existe uma dist?ncia temporal das consequ?ncias mais alarmantes do fen?meno, bem como da efic?cia das a??es de enfrentamento, que tem suas respostas a longo prazo. Torna-se, portanto, de extrema import?ncia a considera??o do futuro, de forma a pensarmos n?o s? nas mudan?as de comportamento refletindo na atualidade, mas em d?cadas e s?culos ? frente. Ao levar em considera??o que as crian?as de hoje experienciar?o as consequ?ncias mais graves do problema, o estudo em quest?o investigou como 46 crian?as de 7 a 10 anos, de duas escolas particulares natalenses percebem as MCGs a partir das informa??es que recebem sobre esse tema. O estudo adotou uma perspectiva multimetodol?gica, que envolveu t?cnicas combinadas de entrevista semiestruturada, desenho e grupo focal com as crian?as participantes, de modo a proporcionar uma abordagem l?dica adequada a esse p?blico. A an?lise dos dados integrou os resultados das tr?s t?cnicas, cujo conte?do possibilitou a cria??o de eixos tem?ticos, relacionados aos referenciais te?ricos dos estudos da Psicologia Ambiental. Os eixos tem?ticos assim obtidos foram: local-global, causa-consequ?ncia, impacto ? vida humana ? aos ecossistemas e mitiga??o ? adapta??o. Os resultados demonstraram que apesar da alta complexidade, os participantes puderam se expressar a respeito do tema, principalmente quando quest?es ambientais foram previamente trabalhadas no contexto escolar. Essa constata??o, aliada ao compromisso manifestado pelas crian?as com medidas de mitiga??o, fornece subs?dios importantes para o planejamento de projetos de educa??o ambiental para este p?blico. / Global Climate Changes (GCC) are generally disclosed and discussed as Global Warming (GW), a term that restricts the problem to an increase in temperature. Besides being just an increase in global temperature, GCC now reaches the public policies sphere, causing interference in the lives of human beings. It is important to point out that in the case of GCC there is a temporal detachment from the current moment to the most alarming consequences of the phenomenon, as well as uncertainty about the effectiveness of mitigation actions, which have their necessarily present long-term answers. It is therefore of utmost importance, consideration of the future, to think not only in behavior changes reflecting today, but in decades and centuries ahead. Taking into account that today's children will experience the most serious consequences of the problem sometime in the future, the study aimed to investigate how 46 children aged 7 a 10 years old from two private schools from Natal perceive GCC through the information they receive about this topic. The study adopted a multi-methodological perspective with the participating children, involving combined techniques of semi-structured interview, drawing and focus group, in order to provide a ludic approach appropriate to this audience. The analysis of the data integrated the results of the three techniques, whose content allowed the creation of thematic axes, related to the theoretical references of the environmental psychology literature. The thematic axes thus obtained were: local-global, cause-consequence, impact on human life ? on ecosystems and mitigation - adaptation. The results showed that despite the high complexity, the participants were able to express themselves about the theme, especially when the topics had been previously treated in the school context. This finding, together with the commitment expressed by children with mitigation measures, provides important subsidies for the planning of environmental education projects for this public.

From these data, in two chapters, the pros and cons of large Brazilian conventional farming on the need to adapt to the current scenario of climate change were analyzed. The fact that Brazil is one of the largest food producers in the world raises its level of importance in global discussions. The analyzes indicate that while agriculture and livestock contributes to economic stability and the country's food, is a powerful delay in the actions of environmental conservation, reduced emissions, agroecological transition and biodiversity conservation. Through official data and theoretical review also found themselves a serious decline of pollinators in the world and the considerable degree of dependence of these by Brazilian cultures. Among the pollinators, Apis mellifera honeybee is the one that stands out and brings more benefits to the human species, is necessary for maintaining global food production and human and animal well-being, through various types of ecosystem services. Because the high level of involvement of Brazil with conventional agriculture and livestock, it was concluded that hardly occur a significant agroecological transition in the short or medium term, which strengthens the need to improve apiculture and national agroecology - still insufficient - as a way of minimize the impacts of global warming and generate more conditions to adaptation / Este estudo parte da an?lise de dados do Quinto Relat?rio do Painel Intergovernamental sobre Mudan?as Clim?ticas ? IPCC, que apresenta de forma cient?fica as implica??es que o aquecimento global ter? sobre os ecossistemas terrestres e a sociedade humana. A partir destes dados, em dois cap?tulos, foram analisados os pr?s e os contras da grande agropecu?ria convencional brasileira em rela??o ? necessidade de adapta??o ao atual cen?rio de mudan?as clim?ticas. O fato do Brasil ser um dos maiores produtores aliment?cios do planeta eleva o seu n?vel de import?ncia nas discuss?es globais. As an?lises indicam que ao mesmo tempo em que a agropecu?ria contribui para a estabilidade econ?mica e alimentar do pa?s, representa um poderoso atraso nas a??es de preserva??o ambiental, diminui??o de emiss?es, transi??o agroecol?gica e conserva??o da biodiversidade. Por meio de dados oficiais e revis?o te?rica, constatou-se tamb?m um grave decl?nio de polinizadores no mundo e o grau consider?vel de depend?ncia destes pelas culturas brasileiras. Dentre os polinizadores, a abelha Apis mellifera ? a que mais se destaca e traz mais benef?cios para a esp?cie humana, sendo necess?ria para a manuten??o da produ??o aliment?cia mundial e para o bem estar humano e animal, atrav?s de diversos tipos de servi?os ecossist?micos. Pelo alto n?vel de envolvimento do Brasil com a agropecu?ria convencional, concluiu-se que dificilmente ocorrer? uma transi??o agroecol?gica significativa no curto ou m?dio prazo, o que fortalece a necessidade de se incrementar a apicultura e a agroecologia nacionais ? ainda insuficientes ? como forma de se minimizar os impactos do aquecimento global e gerar mais condi??es de adapta??o.

For this purpose, we use the Bak-Sneppen model of Evolution, a model developed by Bak and Sneppen (1993) and used in biological systems. The model specifies a number N of agents on an ecosystem, each with a variable that determines the fitness adaptability on this environment. Furthermore, there behavioral rules that are repeated t times in time: 1) the agent with the lowest fitness is selected for mutation, and 2) mutations also occur in the neighboring agents with lower fitness. In this investigation has adapted to the Bak-Sneppen model for the economy, assuminga number N of firms that have two fitness variables, one that represents the technical change and another his care for the environment. To support technical change appealed to the Theory of Induced Technical Change, and climate change to the Theory of Sustainable Development in its complex aspect. From computer simulations of the highlights are three scenarios that describe the complex relationships between technical progress and climate change: the scenario has been called the most probable, and to incorporate the debate is one in which firms aim to maximize their technical and some of them can adopt clean technologies and not others, which makes both systems self-organize at a critical level approximately equal to 0.4 fitness. The adverse scenario is one in which the correlation between technical change and the environment is negative, and technical improvements are polluting and every company that wants to decrease their environmental externalities have to reduce technology. In this scenario, both systems and no changes its threshold is close to 0. Finally, the stage was called the ideal one in which the relationship between technical change and climate change is positive, it is assumed only firms adopt clean technologies. In this, both systems are evolving rapidly, reaching steady state at the threshold of 0.6. / O presente estudo analisa a rela??o entre o progresso tecnol?gico e as mudan?as clim?ticas no plano microecon?mico que apresenta consequ?ncias globais. Para tanto, utiliza-se o modelo de Bak-Sneppen, um modelo desenvolvido por Bak e Sneppen (1993) e que trata da evolu??o biol?gica. O modelo especifica um n?mero N de agentes dispostos num ecossistema, cada um com uma vari?vel fitness que determina sua capacidade de adapta??o relativa a esse meio. Ademais, existem regras comportamentais que s?o repetidas t vezes no tempo: 1) o agente com menor fitness ? selecionado para muta??o; e 2) muta??es tamb?m ocorrem nos agentes vizinhos ao de menor fitness. Nessa investiga??o adaptou-se o modelo de Bak-Sneppen para a economia, supondo um n?mero N de firmas que apresentam duas vari?veis fitness, um que representa a mudan?a t?cnica e outro o seu cuidado com o meio ambiente. Para sustentar teoricamente a mudan?a t?cnica recorreu-se a Teoria do Progresso T?cnico Induzido, e no as mudan?as clim?ticas a Teoria do Desenvolvimento Sustent?vel em seu aspecto complexo. A partir das simula??es computacionais destacaram-se tr?s cen?rios que descrevem as rela??es complexas entre progresso t?cnico e mudan?as clim?ticas: o cen?rio que se chamou de mais prov?vel, por incorporar bem o debate ? aquele em que as firmas objetivam maximizar sua t?cnica e algumas delas podem adotar tecnologias limpas e outras n?o, o que faz com que ambos os sistemas se auto-organizem num n?vel cr?tico aproximadamente igual a 0,4 de fitness. O cen?rio desfavor?vel ? aquele em que a correla??o entre a mudan?a t?cnica e o meio ambiente ? negativa, assim melhorias t?cnicas s?o poluidoras e toda firma que deseja diminuir suas externalidades ambientais tem que reduzir tecnologia. Nesse cen?rio, em ambos os sistemas n?o houve evolu??o e seu limiar fica pr?ximo a 0. Por fim, o cen?rio chamado de ideal foi aquele em que a rela??o entre mudan?a t?cnica e mudan?a clim?tica ? positiva, nele sup?e-se as firmas adotam apenas tecnologias limpas. Nesse, ambos os sistemas evoluem rapidamente, atingindo o estado estacion?rio no limiar de 0,6.

Its aim is to investigate the potential of the school psychologist's actions in promoting changes to the school management practices. Official data show that longer permanence at school does not necessarily result in better education of the students since there is an increase in the number of literate and a decrease in the number of full literate ones. This leads us to think that there seems to be a dissonance between projects supported by the System and the ones that effectively happen at school. We take as theoretical foundations the assumptions of cultural-historical Psychology in that if you understand the human reasons and interests are built on concrete conditions of existence, mediated by instruments of culture, from the relationships established between the subject and the social, and the social and the subject, in a permanent dialectical movement. In the light of the materialistic dialectical and historical method, the data were constructed from the selection of 22 meetings, out of 128 meetings held in the course of the years 2010, 2011, 2012 and 2013, with four managers of a public elementary school, a Director, a Deputy Director and two pedagogical advisors. Both meetings have the audio recording and transcript of the same, and the use of artistic expressions and the synthesis of mediators dialogues undertaken as tools in common. The results revealed that there is a way to work that fluctuates between school managers recognize the challenges that require the transformation of reality and who originate from relationships established between the various agents of the school, and mobilize to overcome them, that we call facing the conflicts, and the mobilization to deny conflicts and move on, that we call look away and that is one of the causes of paralysis in school. It was evidenced that the aesthetic mediations and semiotic, promoted by the arts and for the summaries, enabled the managers to experience two essential movements for making real the changes in exercising the management at school: the migration of emotion and the mobilization of the will. / O presente estudo est? integrado ?s a??es do grupo de Pesquisa Processos de Constitui??o dos Sujeitos em Pr?ticas Educativas PROSPED, da linha de pesquisa Preven??o e Interven??o Psicol?gica, do programa de P?s-gradua??o Stricto Sensu em Psicologia, da Pontif?cia Universidade Cat?lica de Campinas. Objetiva investigar o potencial das a??es do psic?logo escolar na promo??o de mudan?a das pr?ticas de gest?o na escola. Os dados oficiais revelam que a maior perman?ncia na escola n?o tem resultado em melhor escolariza??o dos alunos, na medida em que h? o aumento do n?mero de alfabetizados b?sicos e uma queda no n?mero de alfabetizados plenos. Isto nos leva a pensar que parece haver uma disson?ncia entre os projetos postos pelo sistema e o que ocorre efetivamente na escola. Tomamos como fundamentos te?ricos os pressupostos da Psicologia Hist?rico-cultural em que se compreende que os motivos e os interesses humanos s?o constru?dos nas condi??es concretas de exist?ncia, mediados pelos instrumentos da cultura, a partir das rela??es estabelecidas entre o sujeito e o social e o social e o sujeito, em um movimento dial?tico permanente. ? luz do m?todo materialista hist?rico e dial?tico, os dados foram constru?dos a partir da sele??o de 22 encontros, de um total de 128 reuni?es realizadas no decorrer dos anos de 2010,2011,2012 e 2013, com 4 gestores de uma escola p?blica de Ensino Fundamental I e II, a saber: um diretor, um vice-diretor e dois orientadores pedag?gicos. Em comum os encontros t?m a grava??o em ?udio e transcri??o dos mesmos, a utiliza??o de express?es art?sticas e da s?ntese como instrumentos mediadores dos di?logos empreendidos. Os resultados revelaram que h? um modo de funcionar dos gestores escolares que oscila entre reconhecerem os desafios que se imp?em ? transforma??o da realidade escolar e que emanam das rela??es estabelecidas entre os diversos agentes da escola, e se mobilizarem para super?-los, a que denominamos de enfrentamento dos conflitos e, a mobiliza??o para negar os conflitos e seguir adiante, o que chamamos de desviar o olhar, e que ? uma das causas do imobilismo na escola. Evidenciou-se ainda que as media??es est?ticas e semi?ticas, promovidas pelas artes e pelas s?nteses, possibilitaram aos gestores vivenciarem dois movimentos essenciais para a efetiva??o de mudan?as no modo de exercer a gest?o na escola: a migra??o da emo??o e a mobiliza??o da vontade.
