Studies related to behavior in relation to the practice of physical exercises have attracted the attention of many researchers. However, there is still a lack of investigations on this topic especially among adolescents. The objective of this descriptive-analytical type research was to classify the practice of physical exercise according to the Behavior Change Stages (BCS) theory, according to gender, grade and socioeconomic level. The subjects were high-school adolescents from the city of Recife-PE with average age of 16.2 ± 1.1 (14 to 19 years of age) selected by conglomerate sampling totalizing 2,271 students (1,022 boys and 1,249 girls) from 29 private schools. Social-demographic and BCS characteristics were surveyed by means of the application of a self-report questionnaire. The analysis of data were conducted using the descriptive statistics, the chi-squared test, the Spearman correlation and the MannWhitney U test (p < 0.05). The students presented the following characteristics: 66.3% belonged to economical classes A1 and A2, what evidenced the high purchasing power of the sample. In the group studied, 61.6% of the adolescents were classified as inactive or irregularly active and 26.2% were classified as inactive (precontemplative and contemplative), and in the analysis by gender, boys were physically more active than girls according to grouped BCS. A decline on the practice of physical activities with the grade advance was also verified. The creation of interventions in schools of the region with the objective of encouraging the practice of physical activities is suggested, especially among girls, that contemplate the option selected by the students, and structural reformulations to suit schedule/activity as effective ways to change the behavior in relation to physical activities.
RESUMO A identificação do comportamento empreendedor vem encontrando dificuldades de mensuração, uma vez que os resultados e instrumentos, até então desenvolvidos, não têm apresentado um modelo comportamental de compatibilidade universal para o empreendedor e não têm seguido algumas recomendações encontradas na literatura para a pesquisa em empreendedorismo, considerando elementos circunstanciais e comportamentais. Nesse sentido, visando preencher essa lacuna, este artigo reporta um estudo sobre a construção e validação do Inventário de Barreiras e Facilitadores ao Empreendedorismo, composto por 8 subescalas independentes que mensuram as seguintes facetas: Intenção de Empreender; Risco; Acesso à Capital; Inovação; Oportunidade; Liderança e Gerenciamento; Rede de Relacionamento; Paixão. O estudo parte da premissa de que o indivíduo se depara com Barreiras e Facilitadores, de ordem comportamental e contextual (fatores sociais, econômicos e ambientais), que podem impelir ou inibir a ação de empreender. Por meio de técnicas de validação, chegou-se a um instrumento de baixo custo (lápis e papel) e de fácil aplicação (autorrelato), com parâmetros psicométricos adequados.
Circular economy involves structural changes in traditional business models and consumers’ behavior toward recycled products. The recycling of PET products is increasing but there is still a gap between consumption and demand for PET packaging in Brazil. In this research, waste reduction was examined under a projective scenario to the current ecological purposes in Brazil for reducing environmental pollution. In that manner, this paper aimed to comprehend the intention to purchase recycled PET products of Brazilian consumers. With a non-probabilistic and convenience sample, the study counts 422 participants. The method employed was based on structural equation modelling and partial least Squares, used to test the hypotheses of causality among the variables. Results showed the perception of low quality about recycled products reduced consumers’ intention to purchase. Additionally, the sustainability of recycled products positively influenced the intention to purchase. In addition, recycled products presented a negative impact on the perceived safety, which could influence the purchase of recycled products in Brazil. We conclude that the image that Brazilian consumers have about recycled products positively affects the intention to purchase.
No Brasil, vendedores de rua e comerciantes ambulantes, atualmente reconhecidos como microempreendedores, comumente, vm desenvolvendo em mercados informais estratgias de marketing no convencionais, isto , com caractersticas de intuio, improviso e ilegalidade. Admiravelmente, essas estratgias de comercializao tm demonstrado bons resultados de vendas, pondo em evidncia a seguinte questo: Que tipo de marketing esse, que no est nos handbooks de marketing e negligenciado pelos principais autores da rea? Partindo desse problema, esse estudo tem o objetivo de propor um modelo explicativo para esse fenmeno de marketing, fundamentado teoricamente e dentro de bases empricas, luz de teorias que abordam a composio psicolgica do Jeitinho Brasileiro, a cultura da Informalidade e o Empreendedorismo. Assim, prope-se um conceito que preenche uma lacuna por sobre as teorias tradicionais de marketing existentes.DOI: 10.5585/remark.v13i3.2703
The aim of the present study was to evaluate the use of 2-deoxy-2-(18F)-fluoro-D-glucose (18FDG) positron emission tomography (PET)/computed tomography (CT) in patients with suspected ovarian cancer recurrence and describe the distribution of metastasis. A total of 45 female patients who underwent PET/CT scan due to raised CA-125 levels, clinical suspicion of ovarian cancer recurrence or alterations detected on ultrasound (US), CT or magnetic resonance imaging (MRI) were included in this retrospective study. PET/CT results were compared with histological findings (n=15) or clinical, laboratory and repeated imaging techniques during subsequent follow-up for at least six months (n=30). CA-125 was elevated in 34 patients, 14 patients had clinical symptoms of disease and 23 presented with alterations on US, CT and MRI. A total of 42 patients were confirmed to have ovarian cancer recurrence, all with abnormal findings on PET/CT. Three patients remained free of disease during clinical follow-up, all with normal PET/CT findings. There were 11 patients with raised CA-125 levels and normal conventional imaging, all with positive PET/CT. Among the 11 patients with normal CA-125 levels, eight presented with positive PET/CT scan. Lymph nodes were the most frequent site of relapse of disease, followed by peritoneal implants. Distant sites of metastasis included the liver, spleen, pleura, lung and bone. PET/CT detected unsuspected lesions in 20/45 patients (44.4%). 18FDG PET/CT was a useful tool for evaluating the extent of ovarian cancer recurrence. In the current series, lymph nodes were the most frequent site of relapse of disease, with supradiaphragmatic lymph node metastasis in a large number of cases.
Purpose: The study aimed to verify whether there is a difference of entrepreneurial potential between successful entrepreneurs and entrepreneurs who have failed; and whether there are variables that may work as a means of prediction to the success or failure of an entrepreneur. Originality/gap/relevance/implications: It brings up an innovative approach to the entrepreneurship researches, which main content is in the empirical operationalization of success and failure on business for the testing of specific hypothesis and the identification of the antecedents and consequences of entrepreneurial potential. Key methodological aspects: The research was conducted on a descriptive and quantitative approach. We applied the scale of entrepreneurial potential in 246 entrepreneurs, which 100 correspond to the analysis criteria, operationally, as successful entrepreneurs (n = 50) and entrepreneurs who failed (n = 50). Data were analysed by statistics techniques of logistic regression and Student's t test. Summary of key results: Results show that the successful entrepreneur has higher scores in entrepreneur potential scale than the entrepreneur who failed, in which the main convergence between entrepreneurial potential and business success is the setting business goals. In the investigated sample, the gender showed being a strong predictor of business success, indicating that men have 2.8 times greater chance of success in business than women. Key considerations/conclusions: In our opinion, the results found shed light on crucial elements to the explanation of business success and corroborate recent results brought by research on entrepreneurship and gender.
