Abstract: O Biodiesel é um biocombustível derivado de fontes renováveis como óleos vegetais, gordura animal, óleos egorduras residuais, que na presen a de um catalisador, reagem com o álcool etílico ou metílico, resultando emum combustível de alta qualidade e grande potencial na substitui o de óleo diesel. Essas rea es podem serrealizadas tanto pela rota química (processo convencional) utilizando catalisadores químicos, ácidos ou básicos,quanto pela rota biológica (processo n o convencional) com catalisadores biológicos, enzimas ou célulasimobilizadas. Neste processo químico, a glicerina é separada da gordura ou do óleo gerando dois produtos: umamistura de ésteres alquílicos de ácidos graxos (biodiesel) e glicerina (resíduo da rea o). No entanto, o biodieselpode ser obtido por rota química ou enzimática, ou inclusive através de uma diversidade de processos queincluem, entre outros, microemuls es, pirólise, rea es de esterifica o e transesterifica o. Sendo esta últimaalternativa a de maior ado o do ponto de vista tecnológico por apresentar eficaz convers o de triglicerídeos emésteres metílicos ou etílicos em menor tempo de rea o. Neste contexto, dada à diversidade de processosimplementados atualmente e sendo o conhecimento da matéria prima de qualquer processo industrial umelemento essencial para definir rotas e alternativas tecnológicas eficientes, o presente trabalho discute algumasconsidera es sobre a produ o de diferentes matérias-primas e rotas tecnológicas de processo.

Abstract: In this study were examined associations among physical education instructors’ argumentativeness and socio-communicative styles perceived by students and students’ reasons for discipline. The sample consisted of 252 students (111 males, 141 females) aged 10 - 12 years old (M = 11.4, SD = 0.79) from primary schools of public primary schools who completed three types of questionnaires during physical education classes. The results supported the internal consistency of the instruments. According to the results of the study, statistically significant differences were observed in perceived instructors’ argumentativeness and assertiveness between the two classes of the students. Correlational analysis indicated that perceived instructors’ argumentativeness was positively related to responsiveness, intrinsic reasons, self-responsibility reasons and caring reasons for discipline. Significant negative correlations were noted for instructors’ argumentativeness with assertiveness, external reasons, introjected reasons and no reasons for discipline. The results of regression analysis revealed that perceived instructors’ argumentativeness could significantly predict the variables of responsiveness, assertiveness, external reasons, introjected reasons, intrinsic reasons and self-responsibility reasons for discipline.

Abstract: Esta pesquisa teve o objetivo de identificar um cenário que descreva o turismo de eventos na cidade de Jo o Pessoa/PB, considerando aspectos como planejamento, estratégias e sustentabilidade. Utilizou-se uma abordagem metodológica exploratória através da análise qualitativa, por meio de entrevistas em profundidade. A unidade de análise foi representada pelos gestores públicos e privados ligados diretamente ao setor de turismo de eventos da cidade de Jo o Pessoa/Paraíba. Na avalia o dos resultados observa-se a ausência de uma melhor metodologia que permita aproximar e ampliar os interesses comuns entre os gestores públicos e privados, faltando também uma maior convergência entre as demandas dos gestores privados e o que tem sido ofertado pelos gestores públicos.
