Relationship between Resilience and Self-regulation: A Study of Spanish Youth at Risk of Social Exclusion

The Supplementary Material for this article can be found online at: http://journal.frontiersin.org/article/10.3389/fpsyg.2017.00612/full#supplementary-materialThe ability to self-regulate behavior is one of the most important protective factors in relation with resilience and should be fostered especially in at-risk youth. Previous research has characterized these students as having behaviors indicating lack of foresight. The aim of the present study was to test the hypothetical relationship between these personal variables. It was hypothesized that self-regulation would be associated with and would be a good predictor of resilience, and that low-medium-high levels of self-regulation would lead to similar levels of resilience. The participants were 365 students -aged 15 and 21- from Navarre (Spain) who were enrolled in Initial Vocational Qualification Programs (IVQP). For the assessment, the Connor Davidson Resilience Scale (CD-RISC) and the Short Self-Regulation Questionnaire (SSRQ) were applied. We carried out linear association analyses (correlational and structural) and non-linear interdependence analyses (MANOVA) between the two constructs. Relationships between them were significant and positive. Learning from mistakes (self-regulation) was a significant predictor of coping and confidence, tenacity and adaptation, and tolerance to negative situations (resilience). Likewise, low-medium-high levels of self-regulation correlated with scores on resilience factors. Implications of these results for educational practice and for future research are discussed.Motivational-affective strategies of personal self-regulation and coping with stress in the university teaching-learning process.

Presence of palm oil in foodstuffs: consumers' perception

Purpose - The purpose of this paper is to determine the presence of palm oil in food products on sale, and to study and compare consumers' opinions about this oil type in Spain (importing country) and Peru (producing country). Design/methodology/approach - Recent news published in both countries, which could influence consumer perceptions, were analysed. A study on the labelling of foodstuffs in Spain was carried out, as was a survey with Spanish and Peruvian consumers. Findings - Palm oil was found in a large number of products and in a wide range of foods, especially those from the bakery sector. The percentages of saturated fats varied substantially within the same product type. Spanish consumers showed much more interest in the labelling and information on nutritional properties, especially energy values, saturated fats and sugars, while Peruvians focused more on energy values, and protein, vitamin and mineral contents. In Spain, palm oil was considered the worst quality fat/oil and had a clearly negative effect on both health and the environment. In Peru, palm oil was neither perceived by the majority of respondents as low quality oil nor associated with negative health effects. However, they were aware of the environmental problems that could result from its production. Originality/value - These results confirm that the food industry should make efforts to reduce or replace palm oil in foods, mainly in Spain, as most consumers believe that palm oil negatively affects their health and the environmen

Formation of stellar inner discs and rings in spiral galaxies through minor mergers

Recent observations show that inner disks and rings (IDs and IRs) are not preferentially found in barred galaxies, pointing to the relevance of formation mechanisms different to the traditional bar-origin scenario. Nevertheless, the role of minor mergers in the formation of these inner components (ICs), while often invoked, is still poorly understood. We have investigated the capability of minor mergers to trigger the formation of IDs and IRs in spiral galaxies through collisionless N-body simulations. Our models prove that minor mergers are an efficient mechanism to form rotationally-supported stellar ICs in spirals, neither requiring strong dissipation nor noticeable bars, and suggest that their role in the formation of ICs must have been much more complex than just bar triggering

Glucose uptake in Prochlorococcus: diversity of kinetics and effects on the metabolism

We have previously shown that Prochlorococcus sp. SS120 strain takes up glucose by using a multiphasic transporter encoded by the Pro1404 gene. Here, we studied the glucose uptake kinetics in multiple Prochlorococcus strains from different ecotypes, observing diverse values for the Ks constants (15–126.60 nM) and the uptake rates (0.48–6.36 pmol min-1 mg prot-1). Multiphasic kinetics was observed in all studied strains, except for TAK9803-2. Pro1404 gene expression studies during the 21st Atlantic Meridional Transect cruise showed positive correlation with glucose concentrations in the ocean. This suggests that the Pro1404 transporter has been subjected to diversification along the Prochlorococcus evolution, in a process probably driven by the glucose availabilities at the different niches it inhabits. The glucose uptake mechanism seems to be a primary transporter. Glucose addition induced detectable transcriptomic and proteomic changes in Prochlorococcus SS120, but photosynthetic efficiency was unaffected. Our studies indicate that glucose is actively taken up by Prochlorococcus, but its uptake does not significantly alter the trophic ways of this cyanobacterium, which continues performing photosynthesis. Therefore Prochlorococcus seems to remain acting as a fundamentally phototrophic organism, capable of using glucose as an extra resource of carbon and energy when available in the environment

Methodological resources for the acquisition of competences and the students’ insertion with regard to the reality of homeless people

El proyecto de innovación docente presentado pretende concienciar y sensibilizar a los estudiantes de la realidad de las Personas Sin Hogar (PSH), para adquirir valores de respeto, solidaridad y empatía por este sector de la sociedad, a través de actividades académicamente dirigidas (ADD), empleando una metodología activa y participativa centrada en el trabajo grupal y cooperativo que facilite el logro de competencias propias de su titulación. Para ello, se planificaron una serie de actividades que favorecieron la coordinación horizontal y vertical de las materias participantes en las Titulaciones de Grado en Educación Infantil y de Grado en Educación Primaria del Centro de Magisterio “Sagrado Corazón”. De esta forma, los resultados implican la conexión y continuidad entre las materias participantes. Por último, las conclusiones muestran que los estudiantes universitarios interiorizan los valores necesarios para la transferencia de aprendizajes adquiridos, a través de la experiencia vivencial con la realidad de las PSH, la cual permite una mirada conjunta de la inclusión y la invisibilidad social, empleando un enfoque participativo donde las opiniones e inquietudes de ambos colectivos se tengan en cuenta. Para ello, es preciso no poner barreras excluyentes a la educación del estudiante como futuro docente.The present innovative teaching proyect aims at raising awareness and moving students about the reality of homeless people, in order to acquire values of respect, solidarity and empathy for this society sector, through curricular activities, implementing an active and participatory methodology based on group and cooperative work which promotes the attainment of competences of their own degree. For this purpose, a set of activities that favoured horizontal and vertical coordination of the subjects involved in the Degrees in Early Childhood Education and Primary Education of the “Sagrado Corazón” Teacher Training School were planned. Thus, the outcomes involve the connection and the continuity between the subjects concerned. Finally, the findings show that university students internalize the values necessary for the transfer of learning acquired, through the lived experience with the reality of homelessness, which allows for an overall perspective of inclusion and social invisibility, by applying a participatory approach where views and concerns of both sides are given due consideration. This requires the removal of exclusive barriers to the education of the student as a future teacher

Occurrence of melatonin and indolic compounds derived from L-tryptophan yeast metabolism in fermented wort and commercial beers

Melatonin and serotonin are bioactive compounds present in foods and beverages and related to neuroprotection and anti-angiogenesis, among other activities. They have been described in wines and the role of yeast in their formation is clear. Thus, this study evaluates the content of these bioactives and other related indolic compounds in beer. For this purpose, commercial beers were analyzed by a validated UHPLC-HRMS method and sample treatment optimized due to the low concentrations expected. Moreover, a wort was fermented with different commercial beer yeast (Abbaye, Diamond, SafAle, SafLager) in order to monitor the formation of these bioactives during the elaboration process. Results show that indolic compounds such as N-acetylserotonin and 3-indoleacetic acid are produced during the alcoholic fermentation of wort. Moreover, the occurrence of four indolic compounds (5-hydroxytryptophan, N-acetylserotonin, 3-indoleacetic acid, L-tryptophan ethyl ester) in commercial beers is reported for the first time.Ministerio de Economía y Competitividad AGL2013-47300-C3-2-R, AGL2016-77505-C3-2-
