A Compreensão da idéia do número racional e suas operações na EJA: uma forma de inclusão em sala de aula

The awareness of the difficulty which pupils, in general have in understanding the concept and operations with Rational numbers, it made to develop this study which searches to collaborate for such understanding. Our intuition was to do with that the pupils of the Education of Young and Adults, with difficulty in understanding the Rational numbers, feel included in the learning-teaching process of mathematics. It deals with a classroom research in a qualitative approach with analysis of the activities resolved for a group of pupils in classroom of a municipal school of Natal. For us elaborate such activities we accomplished the survey difficulties and obstacles that the pupils experience, when inserted in the learning-teaching process of the Rational numbers. The results indicate that the sequence of activities applied in classroom collaborated so that the pupils to overcome some impediments in the learning of this numbers

Vou estar fazendo ... um estudo funcionalista de uma (nova) forma perifrástica de futuro

The work in evidence analyzes the use in the ways periphasis of gerund - FPG - (to go+to be+gerund) in the speech (gender class) of the teachers of Natal, Caicó and Serra Negra do Norte, potiguares cities. For that, she opted to constitute corpus, once the data found in other corpora they were inexpressive for the research. The study tries to elucidate the reasons that take the speaker to use a form of larger future in detriment of the more it tans; it investigates as it feels the manifestation of the grammaticalization and demarcation - beginnings givonianos. Besides Givón (1979, 1984, 1990, 1995 e 2001), other authors served as light: Cunha (1986); Bechara (2007); Cunha and Cintra (2007); Perini (2006); Neves (2000, 2006) Silva (2005); Furtado da Cunha and Tavares (2007); Gibbon (2000); Torres (2009). After the study, the results that point the appearance in a new way of future expression emerged, marked and with tendency the grammaticalization

O Ateneu e a nostalgia na forma

The actual study proposes Raul d‟Ávila Pompéia‟s O Ateneu (1888) among the most significant works in Brazilian Literature panorama, according to the perspective of verbal materiality of the Romanesque genre under a form nostalgia sign that, in its turn, ascends to the archaic origin poetry of fable. Along with large rereading of pertinent bibliography, it is gone here toward narrator Sergio‟s crônica de saudades on pursuit of showing it, firstly, as poetic language allegory updated in the novel technique; secondly, as radical metalanguage that still renders problematic several aspects of modern fictional prose

Jornalismo e narrativas transmidias: a reportagem no contexto da convergência

The transmedia storytelling is a phenomenom recently conceptualized theoretically (JENKINS, 2009), arising from ficcional mediatic products and disseminated as well by the use on other fields. This search aims to analyze how the transmedia storytellings can be applied to journalism on the basis of an specific genre, the reporting. To that, take as reference theoretical developments performed by brazilian authors (FECHINE et al., 2011, 2012, 2013), on the basis of televisive fiction, which culminated on concepts as transmediation and transmedia contents and deepened the comprehension and the research in this area. Thenceforth, this study propone a problematization and apropriation of this theoretic support for the journalism field, using, for that, a comprehension of journalistic production on a speech level, as well as its social practices (newsmaking). The empiric research also take two different paths. First, analyze a group of reportings, in which there is transmediation, in order to verifying the configuration of the transmedia phenomenom - more specifically of the transmedia storytelling - and its particularities to journalism. Then, develops an investigation, based on the etnographic method, of the productive routine on the special reporting section of the Jornal do Commercio (Recife/PE), aiming to investigate the conditions of transmediation in this range and the practices that favor and difficult the employment of transmedia storytelling. The result are, therefore, compared and related, with the goal of providing multidimensional view of the phenomenom

Detecção de cor e forma por Callithrix jacchus em cativeiro

Callithrix jacchus studies involving differences between the sexes regarding the performance on tasks food still offers room for the investigation of some factors, among them there is the differences in color vision, which can directly influence the detection of visual clues on food items. This study aimed to analyze the performance of C. jacchus in tasks involving detection of food items. Some factors were analyzed such as the differences in performance between the sexes and behavioral categories present during the task. There were no differences in performance between the animals in carrying out the task, for all situations presented, examining the behavioral categories observed. The fact of the task to be very simple might have influenced the results, and it was not possible to observe differences in performance. Males and females showed the same performance in all analyzed situations. The sex differences were not found possibly due to the influence of external factors, such as the structure of the experimental apparatus. The animals are more efficient in carrying out the task during the morning, in comparison to the afternoon. The light may have been one of the factors that influenced these results. Due to the influence of other factors that probably contributed to these results, we believe that different results can be found in future work

Uma nova forma de calcular os centros dos Clusters em algoritmos de agrupamento tipo fuzzy c-means

Clustering data is a very important task in data mining, image processing and pattern recognition problems. One of the most popular clustering algorithms is the Fuzzy C-Means (FCM). This thesis proposes to implement a new way of calculating the cluster centers in the procedure of FCM algorithm which are called ckMeans, and in some variants of FCM, in particular, here we apply it for those variants that use other distances. The goal of this change is to reduce the number of iterations and processing time of these algorithms without affecting the quality of the partition, or even to improve the number of correct classifications in some cases. Also, we developed an algorithm based on ckMeans to manipulate interval data considering interval membership degrees. This algorithm allows the representation of data without converting interval data into punctual ones, as it happens to other extensions of FCM that deal with interval data. In order to validate the proposed methodologies it was made a comparison between a clustering for ckMeans, K-Means and FCM algorithms (since the algorithm proposed in this paper to calculate the centers is similar to the K-Means) considering three different distances. We used several known databases. In this case, the results of Interval ckMeans were compared with the results of other clustering algorithms when applied to an interval database with minimum and maximum temperature of the month for a given year, referring to 37 cities distributed across continents

Testes em modelos weibull na forma estendida de Marshall-Olkin

In survival analysis, the response is usually the time until the occurrence of an event of interest, called failure time. The main characteristic of survival data is the presence of censoring which is a partial observation of response. Associated with this information, some models occupy an important position by properly fit several practical situations, among which we can mention the Weibull model. Marshall-Olkin extended form distributions other a basic generalization that enables greater exibility in adjusting lifetime data. This paper presents a simulation study that compares the gradient test and the likelihood ratio test using the Marshall-Olkin extended form Weibull distribution. As a result, there is only a small advantage for the likelihood ratio test

Do mundo como norma ao lugar como forma: o uso do território pela estratégia da saúde da família

This work aims to check whether there is a congruence between the purposes of regulations imposed by SIAB and the materiality constitution of places where your information is produced, since our hypothesis is that there is a mismatch between the rules and forms, which means, between reality as it is in places and how the territory is scrutinized by the Family Health Strategy (FHS) as for the performance of their teams as to the generation of their information. For this, the methodology used was the literature, documentary and empirical research, in special about territorialization of the Family Health strategy of Natal-RN. From the empirical mediation was possible to see the gap between full exploration and information produced by the ESF and the reality of the places. Thus, we highlight the importance of considering the conditioning of geographical forms as a guiding principle of the strategy for Family Health
