This study aimed to analyze the characteristics of temperature and air humidity from neighborhoods of Presidente Prudente according to the pattern of land use specific to each of them, over a representative period of winter (July 2011), at different times of day in order to identify the major changes in climatic elements and their causes in urban areas. The work is based mainly on the Monteiro’s theory (1976) of Urban Climate System and for its implementation was used data of temperature and relative humidity of the air in three urban neighborhoods and one rural area. With them, a Chart of Rhythmic Analysis was elaborated for identification of the operating atmospherics systems and basic climate conditions in the period. Were prepared, also, graphs and charts to evaluate and compare the data. There were significant differences in the characteristics of temperature and air humidity between the neighborhoods, especially when compared the urban areas with the rural area

As ilhas da plataforma continental estão isoladas do continente, há cerca de 10.000 anos, após a última elevação do nível dos oceanos. O isolamento, a ocupação de novos habitats e/ou diferentes pressões ecológicas podem ter levado a alterações em caracteres genotípicos, fenotípicos e também comportamentais. Este trabalho visa o estudo dos padrões reprodutivos em populações de Thoropa taophora e suas adaptações no continente e em seis ilhas do litoral Norte do Estado de São Paulo. Como hipóteses tem se que fêmeas das populações insulares possuem ovócitos maiores e em menor número devido à redução na disponibilidade de sítios reprodutivos, e machos insulares devem apresentar testículos maiores e maior agressividade associada à defesa de territórios mais escassos. Foram avaliadas as variações de caracteres reprodutivos, como peso de testículos dos machos, número e tamanho dos ovócitos das fêmeas e esforço reprodutivo de 147 indivíduos adultos de T. taophora (87 machos e 60 fêmeas) de populações provenientes das ilhas de Toque-Toque, Redonda, Prumirim, Gatos, Couves, Porcos Pequena; e três localidades no continente: Tuim Parque - Barra do Una e Praia de Toque-Toque Grande no Município de São Sebastião-SP e Praia Domingas Dias no Município de Ubatuba-SP. Todos os indivíduos analisados foram coletados durante o verão (outubro a março) e encontram-se depositados na Coleção de Anfíbios (CFBH), UNESP - Rio Claro e Coleção do Museu de História Natural (ZUEC), UNICAMP. O comprimento rostrocloacal (CRC) das fêmeas variou de 26,7 – 78,3 mm, ao passo que o CRC dos machos variou de 55 – 93,8 mm. Os machos foram significativamente maiores que as fêmeas em quatro localidades. Nas fêmeas, o diâmetro dos ovócitos da população continental da praia Domingas Dias é maior que nas populações das ilhas dos Gatos, Toque-Toque e Redonda...

Nowadays, there is a search for knowledgment that could be applied in the solution of the problems caused by petrolific activities involving the environment, like the biodiversity preservation and the ecosystems monitoring and management. Foraminifera (Protista) are used as an important tool to the environment characterizarion, because they answer quickly to the fisic-quimic variations and indicate local alterations. The goal of this job is to create models of foraminiferal communities composition through the screening of subsuperficial samples obtained from a core collect from Bertioga Channel, Baixada Santista (SP), trying to understand the influence of the environmental variations along the time upon the indicator species presence, as well as making paleoenvironmentals reconstructions of the area. A 80 cm-core was removed in the outer edge of marsh adjacent to Bertioga Channel, not far from the confluence with the Itapanhaú River. There are presented in abundance, equitability, diversity and species richness obtained in nine samples along the sediment. The lower part of the core is compound by calcareous species (rotalideos and miliolideos) with domain Ammonia (Biofacies 1) and the intermediate and upper parts contain mainly agglutinated species (Biofacies 2 and 3, which is dominated by species of Ammotium). The qualitative and quantitative study of the microfauna of foraminifera present in the core reveals that in recent decades the sampling area passed from a condition of infra-marginal strip under significant coastal marine influence for the condition of inter-coastal swamp covered with mangrove vegetation. This change indicates that the site has undergone a process of sediment progradation, a phenomenon that may have been timely, localized, or a reflection of a relative fall in sea level at the regional level

With the increase of stakeholders and consequently increase of amount of nancial transaction the study of news investment strategies in the stock market with data mining techniques has been the target of important researches. It allows that great historical data base to be processed and analysed looking for pattern that can be used to take a decision in investments. With the idea of getting pro t more than the real indexs' gain, we propose a strategy method of transactions using rules built by algorithm classi cation. For that, diary historical data of Ibovespa index and Petrobras stocks are organized and processed to nding the most important attribute that act decisively when taking a investment decision.To test the accuracy of proposed rules, a non real portfolio management is created, showing the decisions' performance over the real index and stocks' performance. Following the proposed rules, the results show that the strategy of investment give me back a high return that Stock market's return. The exclusive characteristics of algorithms maximize the gain inside the analysed time allowing to determine the techniques' return and the number of the days necessary to double the initial investment. The best classi er applied on the time series and its use on the propose investments strategy will demand 104 days to double the initial capital

Currently zoos and management centers are valuable tools in the maintenance and study of various species. Studies of behavior of captive animals contribute to the improvement of management techniques and the well - being of themselves, encouraging captive breeding and reintroduction also to the natural environment . One of the ways to increase the levels of well-being is the use of environmental enrichment techniques that provide necessary incentives for the welfare of both physical and psychological captive animal . The aim of this study was to identify the types, frequencies and intensities of behavior displayed by three individuals of the species Galictis cuja, belonging to the family Mustelidae and popularly known as lesser grisson , which are captives in municipal zoo in Piracicaba , SP . In addition to evaluating the influence of environmental enrichment techniques on these behavioral parameters. The animals had their behaviors recorded in ethograms through the focal sampling method , 40 hours per person , totaling 120 hours of observation . Were introduced four environmental enrichment techniques related to physical environment, nutrition , perception and cognitive stimulation . At the end, the results of observations before and after the introduction of enrichment techniques were compared and it was possible to observe significant changes in behavior such as run , walk and scratching . The animals were more active and spent longer visible during the day, the enrichment also increased the frequency of social behaviors and the end of the work occurred even attempted copulation , thus showing that the enrichment exerted a positive influence on the behavioral patterns of lesser grisson (Galictis cuja)

As ilhas do litoral do estado de São Paulo estão isoladas desde o final do Pleistoceno, depois da última elevação do nível do mar (cerca de 10.000 anos). Elas apresentam condições diferentes do que as do continente, como por exemplo, a disponibilidade de recursos e pressão de predação. Os anfíbios apresentam pele permeável e assim, de modo geral, são intolerantes à salinidade do mar. Desta forma, as populações de anfíbios insulares podem apresentar variações em comportamentos em relação às populações do continente. O objetivo deste trabalho é avaliar e comparar os hábitos alimentares das populações insulares e continentais de Thoropa taophora, uma espécie endêmica da Mata Atlântica que ocorre em costões rochosos e riachos. Neste estudo, utilizamos os espécimes adultos da coleção de Anfíbios do Departamento de Zoologia, Instituto de Biociências, UNESP, Rio Claro (CFBH), provenientes de duas localidades no continente (Barra do Una e praia de Toque-Toque, município de São Sebastião, SP); e de sete Ilhas do litoral do Estado de São Paulo (Ilha dos Gatos, Ilha de Toque-Toque Grande, Ilha do Prumirim, Ilha Redonda, Ilha de Porcos Pequena, Ilha das Couves e Ilha das Ilhas). Em laboratório, foram medidos a massa corpórea (MC), o comprimento rostro-cloacal (CRC), e a largura da cabeça (LC) de cada indivíduo. O conteúdo estomacal e intestinal foi analisado qualitativa e quantitativamente. Para todas as populações de T. taophora, Formicidae foi o item alimentar mais consumido. Outras categorias como Coleoptera, Araneae e Blattodea também foram representativas. Não houve diferença na riqueza de presas entre as populações de T. taophora. Machos de todas as populações comeram mais formigas do que as fêmeas, no entanto não houve diferença entre a riqueza de presas entre machos e fêmeas. Este estudo foi pioneiro para entender quais...

This work investigates the variance and invariance of subject clauses patterns in spoken and written contemporary Brazilian Portuguese. I analyze four parameters (category and semantic class of matrix predicate, form of embedded clause and mood-tense correlation between matrix and embedded clauses) and show that there is less variance in speech patterns.

In this paper, we investigate the grammatical construction “é claro (que)”, which is characterized as a matrix clause. As it is produced, an argumentative clause is added to the matrix clause in subject position. We analyze oral speech and writing data of contemporary Portuguese and show that the grammatical construction undergoes processes of change, which are identified by desentencialization clauses and grammaticalization process. In addition, by analyzing parameters such as the position of grammatical construction, the presence of copulation and the use of a complementizer, we show that the absence of copulation and a complementizer in the matrix leads to a reduced clause, i.e., a monoclause, and a categorical change of the matrix adjective, which plays the role of functioning adverb.

The researches on sexuality, especially from Foucault’s critical analysis, have been denouncing that the sexual repression also happens through the patterns that suggest a fixed happiness model to be followed, not considering the autonomous development of the subject. The aim of this descriptive-qualitative study was to make a critical analysis of the content of the book Sex and The City, which presents narratives about sexual and love relationships in New York. This analysis evidenciated the reproduction of outdated sexual concepts presented on the following thematic categories: (1) Comprehension of the single woman as lonely and unhappy; (2) Comprehension of the single woman as independent and consumerist; (3) Comprehension that the single woman needs a heterosexual relationship related to the happy romantic ideal; (4) Comprehension of the love relationships as commodities: people as objects of use and exchange. The sexual and love patterns presented by the book demonstrate the repression reproduced uncritically by the mass culture. The Psychology has been an important area of the science to denounce the control of the sexuality from these perverse and ideological patterns.

The concept of gender is relational and refers to the the overcoming of the biological determinism, it has historical and cultural roots going beyond the anatomical differences between men and women. This documental research investigated patterns of sexuality and gender in sexual education books for children and teenagers. Ten books were analyzed, selected in bookstores websites. The content of the books and their illustrations show: 1) stereotypical and naturalized view of femininity and masculinity, 2) patterns of traditional and patriarchal families, 3) romanticized concept of marriage and reproduction, 4) stereotypes of beauty and "normal" body. It is concluded that sexual education books for children and teenagers reproduce normative standards that can stimulate a sexist education and should not be used in works of sexual education without critical reflection.
