The way we see others in intercultural relations: The role of stereotypes in the acculturation preferences of Spanish and Moroccan-origin adolescents

Although the relationship between stereotypes and acculturation preferences has been previously studied from the majority perspective among adults, the perspective of adolescents and minority groups is understudied. This research analyzed the contribution of four stereotype dimensions (i.e., morality, immorality, sociability, and competence) to the acculturation preferences of Spanish adolescents and adolescents of Moroccan-origin, the moderating role of stereotypes in intergroup acculturation discrepancies, and the interaction of stereotypes with acculturation perceptions on acculturation preferences. A sample of 488 Spanish adolescents and 360 adolescents of Moroccan-origin living in Spain, from 12 to 19 years old, reported how moral, immoral, social, and competent they perceive each other to be. Spanish adolescents reported their perception about how Moroccan youth were acculturating in terms of maintaining their original culture and adopting the host culture, and their acculturation preferences in the same dimensions. Adolescents of Moroccan-origin reported to what extent they were maintaining their original culture and adopting the host culture, their acculturation preferences, and their ethnic and national (Spanish) identity. Results showed that adolescents of Moroccan-origin reported more positive perceptions of Spanish youth than conversely. The perceived immorality of the outgroup was important for understanding the preferences for adopting the host culture of both groups, but in the opposite direction. The four stereotype dimensions modulated the majority-minority discrepancies in preferences for cultural adoption. An analysis of the interaction between stereotypes and perceived adoption on acculturation preferences showed that when Spanish adolescents perceived that Moroccan youth were not adopting the Spanish culture, perceived morality and sociability played a role in their preferences for adoption. The less moral and sociable Moroccans were perceived, the more preference for cultural adoption. These findings support the importance of considering stereotypes in acculturation studies of majority and minority groups, as well as the relevance of including these perceptions in interventions aimed at improving intercultural relation

Scutoids are a geometrical solution to three-dimensional packing of epithelia

As animals develop, tissue bending contributes to shape the organs into complex three-dimensional structures. However, the architecture and packing of curved epithelia remains largely unknown. Here we show by means of mathematical modelling that cells in bent epithelia can undergo intercalations along the apico-basal axis. This phenomenon forces cells to have different neighbours in their basal and apical surfaces. As a consequence, epithelial cells adopt a novel shape that we term “scutoid”. The detailed analysis of diverse tissues confirms that generation of apico-basal intercalations between cells is a common feature during morphogenesis. Using biophysical arguments, we propose that scutoids make possible the minimization of the tissue energy and stabilize three-dimensional packing. Hence, we conclude that scutoids are one of nature's solutions to achieve epithelial bending. Our findings pave the way to understand the three-dimensional organization of epithelial organs.España Ministerio de Ciencia y Tecnología BFU2013-48988-C2-1-P and BFU2016-8079

Tuning melatonin receptor subtype selectivity in oxadiazolone-based analogues: Discovery of QR2 ligands and NRF2 activators with neurogenic properties

New multi-target indole and naphthalene derivatives containing the oxadiazolone scaffold as a bioisostere of the melatonin acetamido group have been developed. The novel compounds were characterized at melatonin receptors MT1R and MT2R, quinone reductase 2 (QR2), lipoxygenase-5 (LOX-5), and monoamine oxidases (MAO-A and MAO-B), and also as radical scavengers. We found that selectivity within the oxadiazolone series can be modulated by modifying the side chain functionality and coplanarity with the indole or naphthalene ring. In phenotypic assays, several oxadiazolone-based derivatives induced signalling mediated by the transcription factor NRF2 and promoted the maturation of neural stem-cells into a neuronal phenotype. Activation of NRF2 could be due to the binding of indole derivatives to KEAP1, as deduced from surface plasmon resonance (SPR) experiments. Molecular modelling studies using the crystal structures of QR2 and the KEAP1 Kelch-domain, as well as the recently described X-ray free-electron laser (XFEL) structures of chimeric MT1R and MT2R, provided a rationale for the experimental data and afforded valuable insights for future drug design endeavoursThe authors gratefully acknowledge the following financial supports: Spanish Ministry of Science, Innovation and Universities; Spanish Research Agency; and European Regional Development Funds (grants RTI2018-093955-B-C21 and SAF2015-64948-C2-1-R to M.I.R.-F.; RTI2018-095793-B-I00 to M.G.L., SAF2015-64629-C2- 2-R to F.G.), General Council for Research and Innovation of the Community of Madrid and European Structural Funds (grant B2017/BMD-3827 e NRF24ADCM), Health Institute Carlos III (Miguel Servet II ProgramCP16/00014 and grant PI17/01700 to R.L.).

Anatomical prosection practices in the Occupational Therapy degree. Student anxiety levels and academic effectiveness

CONTEXT. The practice of anatomical dissection and/or prosection on human cadavers is an essential component of human anatomy training programmes. However, this activity can be stressful for inexperienced students when exposed to cadavers for the first time, and it may generate high anxiety levels. The aims of this study are threefold: 1) To analyse the thoughts and feelings of firstyear students of the Occupational Therapy degree about prosection practices; 2) to examine their anxiety levels in relation to these practices; and 3) to evaluate how useful and effective they are as an educational tool for anatomy training. METHODS. This is a before-and-after cross-sectional study of first-year students of the Occupational Therapy degree at the Universidad de Castilla-La Mancha, Spain. These students had not previously participated in prosection practices. An anonymous questionnaire was distributed among the students before and after the practice, in order to examine their feelings and perceptions during the practice. To examine their anxiety levels we used a State-Trait Anxiety Inventory (STAI) questionnaire. To assess their learning outcomes the students had to complete two practical tests of recognition of anatomical structures, one before attending the practice and one immediately after. RESULTS. Basal anxiety levels, measured as trait anxiety (TA), remained stable and did not show significant differences during the practice (p>0.05). Their emotional anxiety, measured as state anxiety (SA), dropped after the practice from 14.7 to 10 points (p<0.05). Before the start of the practice 11 students (19%) showed signs of anxiety, and these remained so at the end of the practical session (p>0.05). As for their academic performance, we observed that the number of students able to pass the test after attending the prosection practice increased notably (by more than 60%). Additionally, 100% of the students recommended that the practice be retained for future courses, giving it an approval rate of 9.1 out of 10. CONCLUSION. Although anatomy is usually an attractive subject for Occupational Therapy students and they value prosection practices positively, they remain a potentially complex and stressful experience. Some students find that their experiences in the dissecting room can upset their emotional balance, however the implementation of coping mechanisms could be a very effective strategy to reduce their anxiety and also to improve their learning outcomes, helping to strengthen their practical 3 knowledge of anatomy as we have observed in this study. The students not only value positively these practices, they also believe that they are an extremely useful tool for both teaching and learning anatomy, and they recommend their routine use as part of the training process
