The effect of previous commitment as an influencer on choice behavior (CC effect) was largely studied in the field of social influence. However, studies of the CC effect have been limited to the influence caused in consumer choice when he chooses for himself and neglected when he chooses for other people. Authors in the field of consumers choices have studied the differences between choosing for themselves versus choosing for others, justified by the psychological distance (CLT ? Construal Level Theory). Studies that analyzed the relations between both theories (CC and CLT) are rare. Some evidences demonstrated the moderator effect of the psychological distance (in its temporal dimension) on the CC effect. The present study aimed to analyze the effect of previous commitment on consumer choice (CC) not only for himself but for others and to check if the social dimension of the psychological distance also plays a role of moderator in the CC effect. For this study it was developed an experiment 2 (Commitment: Yes versus No) x 2 (Type of Decision: for Himself versus for Others) with 180 American participants (between subjects). The experimental group was driven to a commitment manipulation favorable to a healthy cause. There after all the participants were exposed to a choice simulation when they could choose a healthy or an indulgent product. Half of the group was asked to make a choice for themselves and the other half was asked to make a choice for another person. The data was analyzed using logistic regression and ?t? test, according to the type of analysis required. The results demonstrated that the CC effect occurs not only when the consumer chooses for himself but also when he chooses for others. However, the moderator effect of social dimension of psychological distance (CLT) in the CC effect was not confirmed. From these evidences it can be inferred that the previous commitment can be an efficient technique to influence people to make healthier food choices, specially due to the frequency consumers buy food for other people (ex. Family fathers or mothers). / Pesquisadores da psicologia social e profissionais de marketing, historicamente, t?m demonstrado interesse na compreens?o dos processos psicol?gicos envolvidos nas t?cnicas aplicadas para influenciar as escolhas do consumidor. O efeito do comprometimento pr?vio como influenciador do comportamento de escolha (efeito CC) foi amplamente estudado no campo da influ?ncia social. No entanto, o estudo do efeito CC tem se limitado ? influ?ncia causada no consumidor quando este escolhe para si e, negligenciado, quando ele escolhe para outras pessoas. Autores do campo da escolha do consumidor t?m estudado as diferen?as entre as escolhas para si vs. escolhas para o outro, justificada pela dist?ncia psicol?gica (CLT ? Construal Level Theory). Raros s?o os estudos que analisaram as rela??es entre ambas as teorias (CC e CLT). Algumas evid?ncias demonstraram o efeito moderador da dist?ncia psicol?gica (em sua dimens?o temporal) no efeito CC. O presente estudo buscou analisar o efeito do comprometimento pr?vio na escolha do consumidor (CC), tanto nas escolhas para si quanto para o outro, e verificar se dimens?o social da dist?ncia psicol?gica tamb?m exerce papel moderador no efeito CC. Para isso, desenvolveu-se um experimento 2 (Comprometimento: Sim vs. N?o) x 2 (Tipo de Decis?o: para Si vs. para o Outro) com 180 participantes americanos (entre-sujeitos). O grupo experimental passou por uma manipula??o de comprometimento em favor de uma causa saud?vel. Em seguida, todos foram expostos a uma situa??o de escolha por um produto saud?vel ou indulgente. Metade do grupo foi solicitada a fazer escolha para si e a outra metade a escolher para outra pessoa. Os dados foram analisados utilizando-se regress?o log?stica e teste t, conforme o tipo de an?lise necess?ria. Os resultados demonstraram que o efeito CC ocorre n?o apenas quando o consumidor escolhe para si, mas tamb?m quando escolhe para o outro. No entanto, n?o confirmou o efeito moderador da dimens?o social da dist?ncia psicol?gica no efeito CC, sugerindo que podem haver diferentes n?veis de influ?ncia da dist?ncia psicol?gica (CLT) no efeito CC. A partir dessas evid?ncias pode-se inferir que o comprometimento pr?vio pode ser uma eficiente t?cnica para influenciar as pessoas a fazerem escolhas de alimenta??o mais saud?veis, dada a frequ?ncia com a qual os consumidores compram alimentos para outras pessoas (ex.: pais e m?es de fam?lia).

The validation of an instrument has the purpose of verifying whether the mensuration carried out consistently measures what the instrument intends to measure.Nevertheless, to be regarded as a valid one, an instrument must also be reliable,which means that its reliability is required, yet it is not enough for its validity status.This current study of validation has been aimed for assessing the fulfillment of two questionnaires: the Job Content Questionnaire (JCQ), and the Self Reporting Questionnaire (SRQ-20), which were used in the evaluation of labor psychosocial aspects and in the workers mental health respectively. The accomplished research has involved five studies which differed in selected occupations. The analysis was done in two stages; in the first, the evaluation of the SRQ-20 was carried out by examining the ROC curve, factor analysis of tetracoric correlations, multiple correspondence analysis, the internal consistency was evaluated by the formula of Kuder-Richardson (KD-20); in the second stage, the JCQ performance was assessed, in which it has been used statistical procedures such as factor analysis with the extraction method of main components and VARIMAX rotation and calculus of Cronbach s Alpha. The results showed satisfactory indicators of performance for both appraised instruments. The SRQ-20 evaluation revealed the extraction of four factors confirmed by the graphic of the analysis of multiple correspondences, the instrument showed reasonable internal consistency among the scales, the questionnaire performance was satisfactory since it identified symptoms and correctly classified subjects about the suspicion of usual mental disturbs. In general,the JCQ revealed adequacy of its scales to the theoretical model proposed by Karasek, acceptable internal consistency among scales. The good performance of the instruments evaluated in this study showed that these instruments satisfactorily assess what it is intended to be measured and can contribute towards building of indicators of occupational health and efficient policies for the working class. / Scanear

In that article a Kernel Estimator was applied to a sequence of random variables with general state space, which were independent and identicaly distributed. In chapter 2, the estimator?s properties such as asymptotic unbiasedness, consistency in quadratic mean, strong consistency and asymptotic normality were verified. In chapter 3, using R software, numerical experiments were developed in order to give a visual idea of the estimate process / Neste trabalho estudamos um dos m?todos n?o-param?trico: os Estimadores do Tipo N?cleo associado a uma sequ?ncia de vari?veis aleat?rias independentes e identicamente distribu?das com espa?o de estados geral, mais precisamente o trabalho de Campos e Dorea [3]. No Cap?tulo 2 verificamos as boas qualidades dessa classe de estimadores como n?o v?cio assint?tico, converg?ncia em m?dia quadr?tica, consist?ncia forte e normalidade assint?tica. No Cap?tulo 3 com o auxilio do software R temos uma id?ia visual do que ocorre no processo de estima??o

This master thesis deals with the planning of routes and their operating parameters for the tram network in the new Brno city masterplan. The work evaluates operational and capital expenses that are bound up with running and further expanding of the tram system. The numbers of inhabitants and jobs included in 300-meter zones around tram stops were assessed. The calculated values are compared with the current situation. Based on the results, a suitable composition of the vehicle fleet and the order in which new tracks should be constructed is recommended. Further measures are proposed to improve coverage of city territories by the tram system, especially construction of tram ways to other densely populated areas of Brno and the organization of selected transfer points
