Comportamento de escolha de um curso de graduação em administração: o caso de BH-MG

Dissertação (mestrado) - Universidade Federal de Santa Catarina, Centro Tecnológico. Programa de Pós-Graduação em Engenharia de Produção.O presente estudo procura mostrar os resultados obtidos com a utilização do modelo do comportamento de compra de Engel, Kollat e Blackwell (ENGEL, BLACKWELL & MINIARD, 2000), num processo de escolha de cursos de graduação em administração de empresas na cidade de Belo Horizonte. A utilização do modelo tem por objetivo avaliar como se processa a escolha pelos estudantes que almejam um curso de graduação em administração. Nos últimos anos, o mercado voltado para as Instituições de Ensino Superior # IES # que oferecem principalmente o curso de graduação em administração de empresas tem aumentado sensivelmente, dificultando o processo de escolha para os estudantes. Os resultados foram obtidos através do método de estudo de casos, utilizando a pesquisa de campo com alunos de duas IES, localizadas no município de Belo Horizonte. Depois de tabulada e analisada a pesquisa, concluiu-se que o modelo avaliado é eficaz na detecção de influências no processo de escolha, que existe diferença desse processo mas das duas IES pesquisadas, que influências ambientais, com as quais os alunos estão envolvidos, são determinantes da escolha. Concluiu-se, também, que a avaliação obtida pelas IES no provão exerce uma influência maior nos estudantes de classes sociais mais altas. Os resultados da pesquisa constituem instrumentos importantes para que as IES definam uma melhor estratégia de marketing com seus clientes e com o mercado

When Politicians Talk About Politics: Identifying Political Tweets of Brazilian Congressmen

Since June 2013, when Brazil faced the largest and most significant mass protests in a generation, a political crisis is in course. In midst of this crisis, Brazilian politicians use social media to communicate with the electorate in order to retain or to grow their political capital. The problem is that many controversial topics are in course and deputies may prefer to avoid such themes in their messages. To characterize this behavior, we propose a method to accurately identify political and non-political tweets independently of the deputy who posted it and of the time it was posted. Moreover, we collected tweets of all congressmen who were active on Twitter and worked in the Brazilian parliament from October 2013 to October 2017. To evaluate our method, we used word clouds and a topic model to identify the main political and non-political latent topics in parliamentarian tweets. Both results indicate that our proposal is able to accurately distinguish political from non-political tweets. Moreover, our analyses revealed a striking fact: more than half of the messages posted by Brazilian deputies are non-political.Comment: 4 pages, 7 figures, 2 table

O smartphone e sua dinâmica de uso na atualidade como ferramenta de comunicação

Monografia (graduação)—Universidade de Brasília, Faculdade de Comunicação, Departamento de Audiovisuais e Publicidade , Bacharelado em Comunicação Social - Publicidade e Propaganda, 2013.Os smartphones já são parte de uma realidade social global e seu uso está cada vez mais incorporado ao cotidiano da Sociedade da Informação. Seu uso envolve os mais diferentes aspectos culturais e estão relacionados principalmente à comunicação. Na Era da Convergência Midiática, onde as mídias cada vez mais têm se tornado híbridas para atender as demandas de suas próprias audiências, percebe-se uma inversão de fluxos entre os meios e o emissores. O atual trabalho se propõe a compreender a complexidade dessas relações, avaliando o impacto direto dos smartphones no cotidiano e seu potencial enquanto ferramenta de comunicação. A pesquisa se baseia, principalmente, no fenômeno da Cibercultura enquanto referencial teórico, que é diretamente ligado ao surgimento do smartphone

Desigualdades intemunicipais de renda no Rio Grande do Sul: 1985-2001

The authors' main objective in this paper was to evaluate the evolution of inequalities concerning per-capita income among the counties in Rio Grande do Sul, in selected years during the period of 1985-2001. The exam of disparities was based on territorial municipalities. The counties is the territorial unit that allows a more reliable evaluation of the inequality phenomena because of its economic, political and social boundaries. The results of the coeficients of inequalities were then compared with the neoclassic and "myrdalian" hipothesis as well as with some findings of other papers writen by authors living in our state. The papers consulted afirm that the practice of emancipation leads, automatically, to the regional development, thus positively affecting the growth of the State as a whole.A proposição central contida neste artigo é avaliar a evolução das desigualdades intermunicipais de renda "per capita" no Rio Grande do Sul, no período 1985- -2001, em anos selecionados. Para tanto, escolheu-se o município como base territorial para o exame das disparidades. É essa instância espacial que proporciona maior nitidez do fenômeno, além de ser uma formação política, econômica e social que representa uma certa unidade. Os resultados tendenciais dos coeficientes de desigualdades são contrastados com as hipóteses neoclássica e “myrdaliana” e também com algumas conclusões correntes de trabalhos desenvolvidos em nosso meio, que afirmam que a prática emancipacionista leva, automaticamente, ao desenvolvimento local e regional, portanto, do Estado como um todo.

The effect of acute magnesium loading on the maximal exercise performance of stable chronic obstructive pulmonary disease patients

OBJECTIVE: The potential influence of magnesium on exercise performance is a subject of increasing interest. Magnesium has been shown to have bronchodilatatory properties in asthma and chronic obstructive pulmonary disease patients. The aim of this study was to investigate the effects of acute magnesium IV loading on the aerobic exercise performance of stable chronic obstructive pulmonary disease patients. METHODS: Twenty male chronic obstructive pulmonary disease patients (66.2 + 8.3 years old, FEV1: 49.3+19.8%) received an IV infusion of 2 g of either magnesium sulfate or saline on two randomly assigned occasions approximately two days apart. Spirometry was performed both before and 45 minutes after the infusions. A symptom-limited incremental maximal cardiopulmonary test was performed on a cycle ergometer at approximately 100 minutes after the end of the infusion. ClinicalTrials.gov: NCT00500864 RESULTS: Magnesium infusion was associated with significant reductions in the functional residual capacity (-0.41 l) and residual volume (-0.47 l), the mean arterial blood pressure (-5.6 mmHg) and the cardiac double product (734.8 mmHg.bpm) at rest. Magnesium treatment led to significant increases in the maximal load reached (+8 w) and the respiratory exchange ratio (0.06) at peak exercise. The subgroup of patients who showed increases in the work load equal to or greater than 5 w also exhibited significantly greater improvements in inspiratory capacity (0.29 l). CONCLUSIONS: The acute IV loading of magnesium promotes a reduction in static lung hyperinflation and improves the exercise performance in stable chronic obstructive pulmonary disease patients. Improvements in respiratory mechanics appear to be responsible for the latter finding

Combining abilities in green corn genotypes for yield and industrial quality traits

The general and specificcombining abilities and the reciprocal effects of seven hybrids and two open pollination varieties of green corn were evaluated, aiming the formation of base populations to be used as a source of superior inbred lines. For the purpose of this study, two experiments were carried out in Maringá/PR and Sabáudia/PR, during the crop season of 2014/15. The experiments were evaluated in incomplete block design alpha lattice, with three replications. The parents AM811, HTMV1, Cativerde 02 and AL Piratininga were selected based on their ĝi and the following hybrid combinations AM811 x CD316, AM811 x AG1051, AM811 x HTMV1, AM606 x Cativerde 02 and Al Piratininga x AG4051 presented the most desirable ŝij effects. Regarding the reciprocal effects, the genotype AM811 is recommended to be used as male parent in further hybrid combination

Improving lead time in product development process of an agricultural machinery company through value-stream mapping (VSM)

The constant search for process improvement requires a comprehensive knowledge of a company's resources, especially with regard to strategic processes for the organization, such as product development, which is directly related to technological changes and the needs of customers, which are becoming increasingly customized and difficult to meet. The value stream mapping method can help managers identify activities that cause losses in the process and may be effective in reducing the lead time in the product development process. Based on these assumptions, this work presents a case study on the application of value stream mapping in the product development process of an agricultural machinery company. The major sources of waste were identified and the process analyzed using value-stream mapping; proposals for changes were then made in consultation with the personnel involved in the projects. The application of the value-stream mapping method allowed the identification of waste in waiting time and in processing. We observed that if the improvement proposals are implemented, there may be a 41% reduction in the total lead time, which is a significant improvement for the process. Value-stream mapping allowed a simplified view of the process and facilitated the identification of waste and the understanding of process constraints, making value analysis more agile

Antidepressant treatment-emergent affective switch in bipolar disorder: a prospective case-control study of outcome

OBJECTIVE: Treatment-emergent affective switch has been associated to cycle acceleration and poorer outcome, but there are few studies addressing this issue. The aim of this study was to prospectively compare the outcome of patients presenting treatment-emergent affective switch with patients with spontaneous mania, regarding presence and polarity of a new episode and time to relapse. METHOD: Twenty-four patients with bipolar disorder according to the DSM-IV were followed for 12 months. Twelve patients had treatment-emergent affective switch and twelve had spontaneous mania. Patients were evaluated weekly with the Young Mania Rating Scale and the Hamilton Depression Scale until remission of the index episode, and monthly until completion of the 12-month follow-up. RESULTS: Eleven patients with treatment-emergent affective switch had a recurrence on follow-up, all of them with major depressive episodes. In the group with spontaneous mania, six patients had a recurrence: two had a depressive episode, and four had a manic episode (p = 0.069 for new episode, p = 0.006 for polarity of the episode). Patients with treatment-emergent affective switch relapsed in a shorter period than patients with spontaneous mania (p = 0.016). CONCLUSIONS: In this first prospective study, treatment-emergent affective switch patients were at greater risk of relapses, especially depressive episodes, and presented a shorter duration of remission when compared with patients with spontaneous mania
