Um olhar sociolinguístico sobre as interações do teletandem: diversidade e variações linguísticas

This article reports on the diversity and the linguistic variations in e-mails and chat interactions in teletandem interactions. Based on the interface of foreign language acquisition and sociolinguistics, its focus is on linguistic variants under the perspective of the social variations of language, especially regarding standard and non-standard norms of the Portuguese language in a teletandem context. Sociolinguistics offers us resources for the analysis and understanding that we intend to provide about teletandem interactions. We also mention the Teletandem Brasil project, its ideas and theoretical orientations, and also analyze data collected. The findings show that the variations in foreign students´ written production, who are also Portuguese learners, come from fluctuations between the standard and non-standard norms because students still do not have complete communicative competence in the target language.

Influência de variações das normas estéticas na atratividade do sorriso

The work presented here aims to evaluate how aesthetic norm variations influence the perception of attractiveness of a smile according to dentists and laymen. Methods: The smiles in photographs of a man and a woman were digitally changed. Eleven smiles were created for each one: an ideal, control smile - an ideal smile according to accepted norms - and 10 smiles containing individual variations of each of the following norms: a) 2mm and 3mm deviations from the middle line; b) the contour of the smile - contour of a straight smile and contour of a reverse smile; c) the angle of the lateral incisors - a mesial angle of 10° and a distal angle of 10°; d) 0.5mm and 1mm diastema; and e) dental proportion - Alber’s Proportion and Plato’s Proportion. The photographs were evaluated by two specialists in cosmetic dentistry and two laymen using the visual analogue scale. Results: The ideal smile for both genders was well accepted by both the specialists and the laymen. The opinions on the smiles with aesthetic variations varied, some were more positive than others, some were in agreement and some were in disagreement. Conclusion: The absence of deviations favors the perceived beauty of a smile, but some aesthetic variations seem to be better accepted than others. The success of aesthetic treatments depends on the active participation of dentists and patients in the planning stage.

Cálculo e implementação do índice de Desenvolvimento da Gestão Municipal (IDGM) no município de Itabaiana/Se

The scarcity of resources which frequently confronts the State, coupled with demands to provide assistance to a needy population, requires that public administrators formulate efficient and effective policies to pursue its goals. It is fundamental that such policies are based on solid information of existing conditions. As such, the availability of reliable and updated socio-economic indicators is an important tool on which to fundament public policies. The present paper aims to present a Municipal Development Index – Municipal Management Development Index (IDGM) – calculated for the city of Itabaiana/SE, and is divided in two sections. The first discusses the concept of economic development and the evolution of measurement frameworks, with emphasis on the IHD and some of its limitations. The second section describes an estimated IDGM for the city of Itabaiana, as well as its methodology, results, and a brief comparative analysis with four municipalities from the state of São Paulo. Itabaiana’s IDGM reached 849 points (the maximum is 1.000), which infers a good developmental condition.

Estudo de propriedades da resina acrílica termoativada por energia de micro-ondas frente às variações nos procedimentos de inclusão

On heat cured acrylic resins by microwaves energy the action of electromagnetic waves on methylmethacrylate promote the polymerization process. However, part of this energy is absorbed by the gypsum present in the flask and the function of this gypsum is to maintain the characteristics of specimen, nevertheless is unknown in the literature as the amount of water present in this gypsum affects the characteristics of acrylic resin. The proposal of this study was verified if dried gypsum influenced in some properties of the acrylic resins thermally activated by microwaves: presence of porosity, microhardness, roughness, flexural strength and dimensional change. Two different types of acrylic resin for complete denture were utilized: Lucitone 550 e Vipi-Wave and groups were formed: Lucitone 550, polymerization by microwave energy without gypsum treatment; Lucitone 550, polymerization by microwave energy with pretreatment gypsum; Vipi-Wave by microwave energy without gypsum treatment; Vipi Wave, polymerization by microwave energy with pretreatment gypsum; Lucitone 550 control group polymerization in hot water bath. For both situations were performed analysis of microhardness and porosity three different metallic shaped specimens were formed with followed dimensions: 2,0x2,0x2,0cm (8cm3); 2,0x2,0x1,0 (4cm3) e 2,0x2,0x0,5 (2cm3). Standardized wax specimens was used to prepare groups (n=9) and included in glass fiber flasks. The gypsum dry was made by microwave oven cycle (10min and 600W) and then the flasks were maintained in dry oven during two hours. Polymerizations of specimens were made and then polished. Wax patterns #7 obtained from the metal were embedded in plastic flask and following the processes of pressing and polymerization of the resin according to established groups. To evaluate the flexural strength, specimens 65mm x 10mm x 3.0mm from metallic patterns in bar format were made. ...

Studies show that the disciplines of differential and integral calculus have high failure rates in all schools where they are present and, although this problem has been accentuated in recent years, it is not a local phenomenon. It's observed since 1970s in various Institutions of higher education in Brazil. These studies seek to understand the causes of failures and proposals for teaching methodology that aims to help reduce these rates. However, there is a large contingent of students who are successful at the first time that they perform these disciplines. And these cases, although they have not been studied, can contribute greatly to the understanding the aspects that are related to learning of them. And this understanding can lead to attitudes and learning and teaching methodologies that promote the expansion of this success. The fact that these subjects also have high failure rates in the Degree in Chemistry of this Institute, this study aimed to investigate the factors that were relevant to the cases for approval of the students performed for the first time. For this we constructed a questionnaire containing objective questions and open answers. The objective sought to diagnose the profile of these students with regard to age, gender, basic education (elementary and middle school), study habits, concurrent activities, among others. These questions were analyzed using simple statistics. The open-ended questions asked students to indicate that they attribute the success obtained in the disciplines and to suggest modes of study. These questions were analyzed using thematic categorization, a method of content analysis. This questionnaire was completed, voluntarily and without identification, by students who have passed the first time attended the courses Calculus I and/ or Calculus II and had never started another college prior to this. The results indicate that the most relevant factors in this process were dedication and correct habits...
