Different color-promoting treatments were tested on table grape cv. “Flame Seedlees” to evaluate changes on flavonoids such as anthocyanins and the residual ethylene produced. Treatments were spray-applied at the onset of veraison. The control was Ethrel at 250 ppm (ETH), Salicylic Acid at 100 ppm (AS), Melatonin at 25 ppm (MEL) and 1:1 mixtures of ETH+AS, ETH+MEL and AS+MEL. The trials were conducted in triplicate after harvest, measuring Total Soluble Solids (% TSS), total acidity (% tartaric acid), pH, residual ethylene (ppm) and anthocyanin content (mg∙cm-2). It was found that treatments ETH, AS, MEL and ETH+AS reached 16% TSS, standing out with lower values ETH +MEL (14.27%) and AS+MEL (15.17%) (p ≤ 0.05). ETH reached 0.83 ppm of residual ethylene, while a sum effect was appreciated in ETH+AS (0.5 ppm) and ETH+MEL (0.35 ppm), but not beneficial as it did not reflect quality characteristics. Only differences (p ≤ 0.05) in anthocyanin content were recorded between ETH (0.019 mg∙cm-2) and AS+MEL (0.003 mg∙cm-2). The subjective color of the grape bunches in the field made it possible to relate it to the objective results of the analyses performed. This research provides commercially important information on the substitution of Ethrel by natural compounds such as AS and MEL, as they show similar effects on the quality of “Flame Seedless” table grapes. In addition, these compounds do not have an ethylene residual greater than 0.2 mg/kg.
In this paper, a study developed at the University of Seniors in Aragón is presented. The Sono-libro, used as an innovative resource, is assessed in the proposal with an educational and pedagogical purpose. The aim is to understand the motivational and learning perception variation after the incorporation of the Sono-libro in the sample. In this quantitative longitudinal design study, the listening habits of the participants are comparatively analyzed at two moments: The first data collection took place before the implementation of the proposal, and the second collection occurred after the proposal. The sample consists of 116 subjects, with 64.16% being women and an average age of 66 years of age. Data was obtained through a validated ad hoc questionnaire judged by experts. The results of the data collections showed an increase in both motivation and perception of the learning obtained, indicating the benefits of incorporating digital resources into contexts of adult students.
Perceptions of women’s roles and leadership in urban governance vary from country to country and culture to culture. While women are represented and participate fully in political decision-making in some countries, in Togo women’s participation in local governance is still limited. The aim of this research is to analyse perceptions of women’s leadership in urban governance in the communes of greater Lomé. Specifically, the study of the influence of general perceptions of the role of women on the development of their leadership in the urban governance of greater Lomé (i) and the implications of these perceptions on the participation of women in the urban governance of greater Lomé (ii). Semi-structured interviews were conducted in all the town halls of the thirteen greater Lomé autonomous district communes with 222 women and 162 men, i.e., a total of 384 people. The corpus created from the interviews, which were transcribed in their entirety, was analyzed using the theory of social dominance developed by Sidanius and Pratto to explain power relations and inequalities between social groups. The results show that perceptions of women’s participation in urban governance vary and are generally associated with several significant implications. The general perception is that women are not as competent or legitimate as men in political and administrative leadership roles. However, there is a growing recognition of the value of gender diversity in urban governance, with a growing awareness of the importance of including women in decision-making processes. From the point of view of the significant implications of perceptions, positive perceptions favor increased representation of women, innovation, and creativity, strengthening legitimacy, reducing inequalities, and presenting women as positive role models in urban governance.
