A stereotaxic method for small animals using experimentally determined reference profiles
In bats conventional stereotaxic methods do not yield sufficient positional accuracy to allow reliable recordings and tracer injections in subnuclei of the auditory system. In a newly developed stereotaxic system experimentally measured patterns of skull profile lines are used to define the animal's brain position with an accuracy of ±100 Όm. By combining the neurophysiological stereotaxic procedure with a standardization of the neuroanatomical processing of the brains, the location of recordings, stimulations or injections can be readily transformed into brain atlas coordinates. This facilitates the compilation and comparison of data within and among animals. The system is not restricted to use in bats and can be readily adapted to other experimental animals

A Beliefs-based Strategy to Prepare Social Workers for Educational Practices with Asylum Seekers
AbstractThe aim of the present study was to optimise educational interventions with asylum seekers. Asylum seekers (n=284) completed a questionnaire that assessed the theory of planned behaviour constructs. The results highlight the importance of social norms and their perceived control over the decision to stay, when explaining their intention to remain in the host country until the reception of the answer to their asylum request. Moreover, behavioural beliefs about the new life, medical services, the feeling of security, employment and education perspectives were identified as motivators. Educational practices can be developed on the basis of these asylum seekersâ beliefs
Algoritmo como ferramenta de apoio Ă decisĂŁo para avaliação de sustentabilidade na introdução de novas tecnologias agrĂcolas.
Resumo: A avaliação dos impactos das tecnologias agrĂcolas pode ser uma aliada do processo de decisĂŁo. Este trabalho apresenta uma metodologia para a avaliação dos impactos de inovaçÔes tecnolĂłgicas com adequaçÔes para a avaliação integrada das tecnologias agrĂcolas e suas aplicaçÔes, fornecendo informaçÔes organizadas de acordo com critĂ©rios e indicadores nas diversas dimensĂ”es onde os impactos da liberação ou utilização da tecnologia agrĂcola podem ser percebidos. O mĂ©todo consiste de um sistema que permite a anĂĄlise do cenĂĄrio no qual a tecnologia serĂĄ introduzida, a partir da geração do Ăndice de significĂąncia e a avaliação do desempenho da inovação, pela anĂĄlise dos indicadores de impactos que irĂŁo compor o Ăndice de magnitude. Este sistema conta com uma ferramenta de apoio, o software "Inovatec-AGRO", com informaçÔes apresentadas como um norteador para permitir uma avaliação instruĂda e embasada. Abstract: Agricultural technology impact assessment may be a helpful tool in the decision-making process. The present work suggests a method to evaluate the impact of technological innovation, with adequacy to assess agricultural technology providing information organized according to criteria and indicators in several areas where the innovation can be perceived, focusing the complexity of the innovation under investigation. The method consists of a system that allows the analysis of the innovation range starting from the generation of the significance index, and the assessment of the innovation performance through the analysis of the performance indicators which will compose the magnitude index. This system has a support tool, the software ?Inovatec-Agro?, with information shown as a guide to allow a well-informed and a well-based evaluation
Gender Differences in Psychosocial Determinants of University Students' Intentions to Buy Fair Trade Products
This study examined gender differences in university studentsâ intentions to buy fair trade (FT) products through the lens of the moral-norm-extended theory of planned behaviour (TPB). Data were obtained from 782 students at the University of Luxemburg. Results of structural equation analysis indicated that the inclusion of moral norms increased the explained variance in behavioural intentions from 62% to 68%. Compared to men, women reported more favourable attitude, higher moral obligation, and stronger intentions toward buying FT products. Moderating analyses showed that the attitudeâintentions relationship was stronger for men, whereas the perceived behavioural controlâintentions relationship was stronger for women. The implications of the moderation analysis are that sustainability professionals seeking to encourage university studentsâ intentions to buy FT products should develop gender-targeted interventions: for men, more emphasis should be placed on attitude toward buying FT products (i.e., the advantages of adopting this behaviour), and for women, more emphasis should be placed on perceived behavioural control (e.g., factors that facilitate the purchase of FT products)
Perinatal and social risk of poor language, memory, and learning outcomes in a cohort of extremely and very preterm children
Children born extremely preterm (EPT) or very preterm (VPT) are at risk of neurodevelopmental impairment. How the interaction between biological and social risk factors affects cognitive development has not yet been completely understood. The objectives of this study are to analyze and compare the language, memory, and learning outcomes of five-year-old children born EPT (<28 weeksâ gestational age) and VPT (28â31+6 weeksâ gestational age) and to determine the risk of having poor outcomes attending to perinatal and maternal characteristics. The analysis included 377 children born VPT (n = 284) and EPT (n = 93) in 2011â2012. Maternal, neonatal, and clinical information was obtained at birth, and maternal education was obtained at five years using a parental questionnaire. At five years, the language, memory, and learning outcomes were assessed with the developmental NEuroPSYchological assessment second edition (NEPSY-IIÂź). Logistic regression models were applied to assess the association of biological and social risk factors with performance below the expected level for the childâs age in language, memory, and learning subtests. Lower maternal age and education increased the odds of having language performance below the expected level for the childâs age, while lower maternal educational level and gestational age increased the likelihood of having memory performance below the expected level. Children living in the most social disadvantage contexts are at a higher risk of suboptimal cognitive development. Implementing intervention programs in disadvantaged contexts and targeting specific cognitive domains may enable EPT and VPT children to reach and fulfill their potential in society. © 2022 Informa UK Limited, trading as Taylor & Francis Group.This work is financed by national funding through the FCT - Fundação para a CiĂȘncia e a Tecnologia, I.P., in the scope of the projects UIDB/04750/2020 e LA/P/0064/2020

Empirical evidence for unique hues?
Red, green, blue, yellow, and white have been distinguished from other hues as unique. We present results from two experiments that undermine existing behavioral evidence to separate the unique hues from other colors. In Experiment 1 we used hue scaling, which has often been used to support the existence of unique hues, but has never been attempted with a set of non-unique primaries. Subjects were assigned to one of two experimental conditions. In the "unique" condition, they rated the proportions of red, yellow, blue, and green that they perceived in each of a series of test stimuli. In the "intermediate" condition, they rated the proportions of teal, purple, orange, and lime. We found, surprisingly, that results from the two conditions were largely equivalent. In Experiment 2, we investigated the effect of instruction on subjects' settings of unique hues. We found that altering the color terms given in the instructions to include intermediate hues led to significant shifts in the hue that subjects identified as unique. The results of both experiments question subjects' abilities to identify certain hues as unique
