The aim of this research is to study the mediating role of the learning process in explaining the relationships between certain psychological and biographical characteristics and entrepreneurial intention. The findings suggest that the effect of psychological and biographical aspects on entrepreneurial intention depend on the extent to which students are able to take advantage of their personal capabilities in order to develop an effective learning process. Learning process factors (information about course guides, student effort and educational processes) mediate the relationships between specific psychological factors (achievement need, internal control and autonomy) and entrepreneurial intention. With regard to biographical factors, we find no mediating effect on entrepreneurial intention through the learning process. The present study provides a better understanding of the antecedents of entrepreneurial intention, helping to fill the gap in the literature.

Measurements from a certain population may show a similar pattern that allows an alteration to be easily recognized and enable a better surgical approach. In our population, the changes in the anthropometric measurements of the lips are unknown, so our objective is to determine the variations in these measurements by decades of age to achieve a better aesthetic and reconstructive surgical approach. Anthropometric measurements of the lips were taken with a vernier in relation to the previously marked anatomical points. The sample consists of 174 patients who came for care not related to labial pathologies with ages between 20 and 80 years with Mexican nationality. We use the sample calculation formula to estimate an average, with an alpha error of 0.5 and a tolerance of 2 mm of the data for the measurements of the height of the lower face with an average measurement of 56.2 mm and a SD of 8.87 mm of the Marzena’s article. Wyganowska-Świątkowska and colleagues Average measurements were obtained, where a progressive longitudinal increase in measures: al-ch, sbl-cph, sn-Is, li-sto, cph-Is, li-sl, ch-li, li-pg according to aging is confirmed. In contrast, the ch-cph and ch-sbl measures, remain the same despite the aging, showing greater changes in the sagittal plane than in the parasagittal. The study only shows measures of length, so caring out a magnetic resonance imaging study to also measure the volume and perform it with a larger sample to have the optimal standard is further needed.
