O objetivo deste artigo a apresentao de um exemplo de forma mais didtica de uso da modelaem de Equaes Estruturais com o software SmathPLS 2.0 M3. O referido programa usa o mtodo de Mnimos Quadrados Parciais e busca atender situaes muito frequentes na pesquisa de Marketing: Ausncia de distribuies simtricas das variveis mensuradas, teoria ainda em fase inicial ou com pouca cristalizao, modelos formativos e/ou quantidade menor de dados. O uso crescente do SmartPLS vem mostrado a robusteza e aplicabilidade do modelo nas pesquisas da rea.DOI: 10.5585/remark.v13i2.2717

This paper identifies challenges and opportunities for enhancing higher education in entrepreneurship considering student perceptions concerning both their demand for entrepreneurship education and their entrepreneurial intention as well as previous studies that present the points of view of experts. The main focus is Brazilian higher education, but the results address challenges that cross borders, such as the need for a practical approach. The study analyzed the data from the Brazilian version of the 2011 Global University Entrepreneurial Spirit Students' Survey (GUESSS) obtained with an online questionnaire answered by 25,751 Brazilian students from 37 colleges and universities. To give a reference for a better understanding of Brazilian statistics, data were compared to those of the 2011 international GUESSS involving also 25 other countries and 64,079 responses from them. Three hypotheses were tested. The results show that entrepreneurship education has a significant negative effect on student entrepreneurial intention and also on self‐efficacy. The same occurs between entrepreneurial intention and students' demand for entrepreneurship education. Brazilian students present higher levels of entrepreneurial intention and are significantly more motivated to take courses and activities in entrepreneurship than those students in the international sample. Approximately 50 percent of Brazilian students are potential entrepreneurs. One of the opportunities identified is to take advantage of students' positive attitudes and their high demand. The opportunities could play an important role in overcoming the challenges recognized, among which are the need for a more practical approach and the need for larger and diversified educational offerings beyond business planning. The challenges make Neck and Greene's recommendations, presented in a 2011 issue of JSBM, particularly important for Brazil. The last three sections propose different explanations, suggestions for more research, and practical recommendations.

Purpose This paper aims to present the fundamental aspects for the development and validation (D&V) of attitudes’ measurement scale, as well as its practical aspects that are not deeply explored in books and manuals. These aspects are the results of a long experience of the authors and arduous learning with errors and mistakes. Design/methodology/approach The nature of this paper is methodological and can be very useful for an initial reading on the theme that it rests. This paper presents four D&V stages: literature review or interviews with experts; theoretical or face validation; semantic validation or validation with possible respondents; and statistical validation. Findings This is a methodological paper, and its main finding is the usefulness for researchers. Research limitations/implications The main implication of this paper is to support researchers on the process of D&V of measurement scales. Practical implications Became a step-by-step guide to researchers on the D&V of measurement scales. Social implications Support researchers on their data collection and analysis. Originality/value This is a practical guide, with tips from seasoned scholars to help researchers on the D&V of measurement scales.

A modelagem de equações estruturais com estimação por mínimos quadrados parciais (PLS-SEM) tem sido empregada nas mais variadas áreas de pesquisa, aumentando a quantidade de artigos publicados com o uso desse método de modo exponencial. Há vários motivos para que isso esteja ocorrendo, mas um deles é o fato do software SmartPLS ter facilitado o uso do PLS-SEM. Este artigo tem o objetivo de apresentar sete exemplos didáticos com conjuntos de dados reais e disponíveis àqueles que queiram aprender ou ensinar PLS-SEM, tratando de temas como: avaliação do modelo de mensuração, avaliação do modelo estrutural, multicolinearidade, variável latente de segunda ordem, mediação, moderação com variável numérica e categórica (MGA – multi-group analysis).

We report an increased incidence of high relapse risk features in 157 APL Brazilian patients. Out of 134 patients treated with ATRA and anthracyclines, only 91 (67.9%) achieved remission because 43 (32%) died during induction. The death rate during consolidation was 10.5%. Bleeding complications were the most frequent cause of failure (21.6%).
