It was hypothesized that the regional consequence of the global warming and the warming of surface water could substantially contribute the significant growth of the aquatic macrophytes in the years 2008-2009. The growth of these vegetation believed to be improved the degree of water transparency and as a consequence of the improved growth of phytoplankton species and chlorophyll biomass. At the same time the aquatic macrophyte could interact and compete potentially for the dissolved inorganic nutrients resources and the phytoplankton community. This study presents a comparison of years 2004-2005 when it did not have the expressive presence of the aquatic macrophyte community or restricted to the littoral region. In contrast, the years 2008-2009 showed a significant growth of the aquatic macrophyte in the Cruzeta/RN impoundments. The present study is an attempt to elucidate the significant presence of the aquatic macrophyte, Eichhornia crassipes, Ceratophyllum submersum, Nymphea sp and Pistia sp, and its interference on the ecology of phytoplankton. The samplings had been carried out from September of 2008 to April of 2009 and consistently between 10:00 h and 12:00 h with the aid of Van Dorn bottle and the plankton net of mesh size 20 Qm. The collections were made in three depths ie., surface, mid-column and bottom. The Physical-Chemical parameters such as pH, temperature, electrical conductivity and dissolved oxygen had been analyzed in situ. The samples for analysis of nutrients and chlorophyll were kept under refrigeration for posterior analysis in the laboratory. Phytoplankton samples were preserved in Lugol-iodine and kept for sedimentation for quali-quantitative analysis of phytoplankton. Enumeration of cells, colonies and filaments was done with the aid of Sedgwick-Rafter counting chamber and expressed as numbers/ml. Chlorophyll a was analyzed as a functional component of phytoplankton biomass and extracted with cold 90% acetone. The results indicate that the chlorophyll concentration varied between 5,65-8,08 Qg.L-1 for the dry period and 5,09-6,23 Qg.L-1 for the rainy period and showed considerable reduction when compared to the values to the 2004-2005 study period. The temperature was always presented higher in relation to the 2004-2005 study. Phytoplankton species showed a relative abundance of the Cyanophyceae for both the period of dry and rainy. The predominance species are filamentous Leptolymbya geophila Borzi (Planctolyngbya sp), Anabaena plankct?nica Brunnthaler, Oscillat?ria limosa Ag. and Cylindrospermopsis raciborskii (Wolosz). The concentration of the nutrients such as nitrate and orto-phosfato had always presented higher values during the rainy period and the ammoniacal nitrogen retained moderate values in the dry period and a slight increase in rainy season. The main conclusions are the reduction of the concentration of chlorophyll, diversity of phytoplankton, and the increase in temperature and transparency of the water during the period of the study / O a?ude Cruzeta, situado no munic?pio de Cruzeta do estado do Rio Grande do Norte, tem import?ncia significativa, pois representa a ?nica fonte de abastecimento de ?gua para este munic?pio. Nos anos de 2008-2009 como consequ?ncia regional do aquecimento global houve crescimento significativo das macr?fitas aqu?ticas, estas por sua vez, importantes em ecossistemas aqu?ticos rasos por estabilizar o grau da transpar?ncia da ?gua, aumentando assim a penetra??o de luz e consequente crescimento fitoplanct?nico. Ao mesmo tempo as macr?fitas aqu?ticas tamb?m competem potencialmente com a comunidade fitoplanct?nica por recursos como os nutrientes inorg?nicos. Este estudo apresenta uma compara??o entre os anos de 2004-2005 durante qual n?o houve a presen?a da comunidade de macr?f?tas aqu?ticas ou foram apenas restringidas nas margens e nos anos 2008-2009 em que houve um crescimento significativo das macr?fitas aqu?ticas no a?ude de Cruzeta, RN. O trabalho elucida a presen?a significativa das macr?fitas aqu?ticas, Eichhornia crassipes, Cerathophyllum submersum, Nymphea sp e Pistia sp, e sua interfer?ncia na estrutura do fitopl?ncton. As coletas foram realizadas entre agosto de 2008 at? o julho de 2009 entre as 10:00 e 12:00 h da manh? com o auxilio de garrafa de Van Dorn e rede de pl?ncton de malha de 20 Qm, em tr?s profundidades, superf?cie, meio e fundo. Os par?metros f?sico-qu?micos foram analisados in situ. As amostras para an?lise de nutrientes e clorofila a foram mantidas sob refrigera??o para an?lise. Para an?lise quali-quntitativa do fitoplancton foi ultilizada a c?mara de Sedgwick-Rafter. Os resultados indicam que houve redu??o nos valores da clorofila a em rela??o ao per?odo de 2004-2005, no qual as m?dias variaram entre 5,65-8,08 QgL-1 para o per?odo de estiagem e 5,09-6,23 para o per?odo chuvoso. Enquanto que no per?odo de 2008-2009 foi verificado 3,98-5,65 QgL-1 da clorofila a para o per?odo de estiagem e 3,56-4,36 QgL-1 para o per?odo chuvoso. A temperatura apresentou-se sempre mais elevada em rela??o ao estudo de 2004-2005. No presente trabalho, a classe que apresentou maior abund?ncia relativa para ambos os per?odos foi a Cyanophyceae, representadas com destaque as esp?cies Leptolymbya geophila Borzy (= Planctonelymbia sp), Anabaena plankct?nica Brunnthaler e Oscillat?ria limosa Ag. e Cylindrospermopsis raciborskii (Wolosz). Ocorreu redu??o na concentra??o de clorofila a e diversidade do fitopl?ncton, aumento da transpar?ncia e aumento da temperatura da ?gua, durante o per?odo em estudo, estes fatores podem ter sido ocasionados pela elevada biomassa de macr?fitas aqu?ticas quando comparada ao per?odo de 2004-2005 em que houve uma baixa biomassa de macr?fitas, neste ecossistema

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.

Pesquisa do Estado da Bahia - FAPEB / The verbal future tense in Portuguese is a variable phenomenon currently expressed by the verb forms: the simple future tense, the periphrasis with go + infinitive, the indicative present tense, and the gerundive future form. Among them, the simple future tense is the standard way, and the periphrastic future form is considered by grammarians like a colloquial form of the language. Several studies (GIBBON, 2000; OLIVEIRA, 2006; BRAGAN?A, 2008; SILVA, 2010; TESCH 2011; SANTOS, 2012) have attested to this variable phenomenon throughout history of the Portuguese language and point to the implementation of the periphrastic way of to go + infinitive as a possible replacement of the simple future tense. According to these studies, this change is almost complete in speech and is already invading writing. With this information about the uses of the verbal future tense in Portuguese, in this study, we analyzed data of high school students from public and private schools in the city of Irar?-Ba, within a variational and functionalist perspective, with a synchronic study, in order to observe the presence of the periphrastic future form in school texts, considering the process of grammaticalization. The results of the verbal future tense in school writing of the first, second and third classes of high school, with the control of various groups of linguistic and sociolinguistic, factors, showed that the variant that more customarily occurs in spoken language (the periphrastic future form) is also present in written language. The results show that the phenomenon under study is motivated by factors such as type of school, verbal paradigm, residential area, syntactic status of verb, verb conjugation, thematic role of the subject, semantic nature of the verb, type of subject and type of verb. It was evident through the review that there is an ongoing change process towards the simple future form, more used in texts written by speakers said "cults", be replaced by the periphrastic future form, commonly founded in speech, suffering less normative pressures. / O futuro verbal na l?ngua portuguesa ? um fen?meno vari?vel que, atualmente, ? expresso pelas formas verbais: futuro simples, per?frase com ir + infinitivo, presente do indicativo e futuro gerundivo. Dentre elas, o futuro simples ? a forma padr?o, enquanto o futuro perifr?stico ? considerado pelos gram?ticos uma forma coloquial da l?ngua. V?rios estudos (GIBBON, 2000; OLIVEIRA, 2006; BRAGAN?A, 2008; SILVA, 2010; TESCH 2011; SANTOS, 2012) t?m atestado esse fen?meno vari?vel ao longo da hist?ria da l?ngua portuguesa e apontam para a implementa??o da forma perifr?stica com ir + infinitivo como poss?vel substituta da forma de futuro simples. Segundo tais estudos, esta mudan?a est? quase conclu?da na fala e j? est? invadindo a escrita. De posse dessas informa??es acerca dos usos do futuro verbal na l?ngua portuguesa, neste estudo, faz-se uma an?lise de reda??es de alunos de Ensino M?dio de escolas p?blicas e particulares na cidade de Irar?-Ba, dentro de uma perspectiva variacionista e funcionalista, a partir de um estudo sincr?nico, com o intuito de observar a presen?a do futuro perifr?stico em reda??es escolares, considerando o seu processo da gramaticaliza??o. Os resultados encontrados sobre o futuro verbal nas reda??es escolares das turmas de primeiro, segundo e terceiro anos do Ensino M?dio, a partir do controle de v?rios grupos de fatores lingu?sticos e sociolingu?sticos, demonstraram que a variante que ocorre mais costumeiramente na l?ngua falada (futuro perifr?stico) tamb?m se faz presente na l?ngua escrita. Os resultados revelam que o fen?meno em estudo ? motivado por fatores como tipo de escola, paradigma verbal, zona residencial, estatuto sint?tico do verbo, conjuga??o verbal, papel tem?tico do sujeito, natureza sem?ntica do verbo, tipo de sujeito e tipo de verbo. Ficou evidente, atrav?s da an?lise realizada, que h? um processo de mudan?a em curso no sentido de a forma de futuro simples, mais usada em textos escritos por falantes ditos ?cultos?, ser substitu?da pela forma perifr?stica, comumente encontrada na fala, que sofre menos press?es normativas.

Pesquisa do Estado da Bahia - FAPEB / We analyze the realization of the future tense in the political discourse of the three largest cities of Bahia, Salvador, Feira de Santana, and Vit?ria da Conquista, based upon the Variacionist Sociolinguistics. Some sociolinguistic researches indicate a change in progress on the use of the future tense in Brazilian Portuguese, whereupon the standard variant, the simple future form, has been replaced for the periphrastic form (ir + infinitive). These researches show that this change has been completed in the speech and is already reaching writing. This research verify this change in progress in the political discourse, a formal textual genre with features of speech and writing. Some contexts promotes the progress of the periphrastic form, like: a) verbs with three or more syllables; b) younger age group; c) agent subject; d) less stylistic monitoring speech; e) second verbal person; f) regular verbs; g) first event in a serial (about parallelism). The results also show the superiority of the periphrasis ir ?to go? + infinitive; indicate the decline of simple future form; confirm that the simple present tense is used in very specific contexts; show the existence of periphrasis with gerundive forms, called ?gerundismo?, in the standard speech; and indicate the final stage of process of change analyzed. / Analisa-se a express?o do tempo futuro no discurso pol?tico das tr?s maiores cidades baianas, Salvador, Feira de Santana e Vit?ria da Conquista, com base na Sociolingu?stica Variacionista. Diversos estudos atestam que h? uma mudan?a em curso no uso do futuro verbal no portugu?s brasileiro, no qual a forma padr?o, futuro simples, est? sendo substitu?da pela forma perifr?stica ir + infinitivo, tais estudos mostram que a referida mudan?a est? sendo completada na fala e j? est? atingindo a escrita. Este estudo verifica o est?gio dessa mudan?a no discurso pol?tico, g?nero textual formal que apresenta caracter?sticas tanto da fala quanto da escrita. Determinados contextos mostraram favorecer o espraiamento da forma perifr?stica, tais como a) verbos com tr?s ou mais s?labas; b) faixa et?ria mais jovem; c) sujeito agente; d) menor monitoramento estil?stico; e) segunda pessoa verbal; f) verbos regulares; g) primeira ocorr?ncia de uma s?rie (tratando-se de paralelismo). Os resultados tamb?m revelam a predomin?ncia da per?frase ir + infinitivo; apontam a queda do futuro simples; reafirmam que o presente do indicativo ocorre em contextos bastante espec?ficos; revelam a ocorr?ncia de per?frase com ger?ndio, o chamado ?gerundismo?, na linguagem formal e indicam que o processo de mudan?a em an?lise est? em fase de completude.

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.
