The impact of exercise training on the lipid peroxidation metabolomic profile and respiratory infection risk in older adults

Aging is associated with oxidative stress that may increase susceptibility to respiratory infections (RIs). We aimed to assess the impact of exercise training on the risk of RIs in older adults and on a targeted metabolomic profile of stress oxidative lipid peroxidation-related metabolites. Methods: In an 8-month clinical trial, 38 participants over 60 years of age were allocated to an exercise group (EG), in which participants underwent 90-min training sessions three times/week(n?=?20), or a control group (CG), in which participants maintained daily physical activities(n?=?18). Daily respiratory symptoms and RIs number and severity were collected. Serum by-products were assessed by comprehensive two-dimensional gas chromatography coupled to mass spectrometry with time of flight analyzer. Serum metabolomic profiling comprised 76 metabolites (alcohols, aldehydes, alkanes, and ketones). Principal components analysis and ANOVA-simultaneous component analysis were used to evaluate the metabolomic profile change. Results: The odds ratio of RIs for the EG was 2.0 CI 95% [0.2;25]. The incidence of RIs was 47% [23;70] in the EG vs. 44%[12;77] in the CG. The metabolomic profiling showed that alkanes and aldehydes classes differed between the EG and the CG before and after intervention. A calibration model showed a relation between the metabolites from four main classes (ketones, alcohols, alkanes and aldehydes) and the prediction of the number of RIs. Conclusion: Moderate exercise training, in older adults, compared with no exercise in controls, did not show a difference in the risk of RIs. A pattern of lipid peroxidation was associated with the number of RIs.     

Addressing the big picture: Deaf children and reading assessments

In the field of education, there is a great emphasis placed on literacy, from reading fluency to writing. There are various approaches that teachers can use in their classroom to design and identify needed areas of instruction, but these approaches do not always apply to Deaf Education. The act of using the same assessments throughout all student populations presents some potential issues, particularly the question of whether or not the students’ actual literacy abilities are being identified. The focus is to spotlight a frequently used approach for measuring reading fluency and present an alternative approach.     

MNC commitment, OCB role definition and intent to leave in subsidiary top managers: The moderating effect of uncertainty avoidance values

The current paper analyses in depth and expands on the study of the consequences of organisational commitment in the MNC setting. To that end the moderating effect of uncertainty avoidance as a personal cultural value is studied and two consequences of MNC commitment are analysed: intent to leave and organisational citizenship behaviour. The empirical analysis carried out on a cross-organisational sample of 101 top managers of MNC's subsidiaries located in Spain confirms the moderating role of uncertainty avoidance for the affective and normative commitments, as well as its moderating effect on the influence that organisational citizenship behaviour role definition exerts on intent to leave. Implications for management theory and practice are discussed.     

Gender differential in self-assessment: a fact neglected in higher education peer and self-assessment techniques

This paper analyses student cross-assessment with a gender perspective in three different courses along several academic years in an engineering school in Spain. The aim of this study is to contribute to a wider understanding of the hidden effect of gender in higher education by testing if gender has any effect on the way students assess others and themselves. Previous research has demonstrated sex differences in self-image and self-confidence, which are both closely related to self-esteem and same- and other-sex esteem. It follows that gender effects might be expected in investigations on peer and self-assessment (PSA), as both techniques are closely linked to self-image and self-confidence. But a critical review of the literature on PSA with a gender perspective reveals that findings on this field are inconclusive, thus more research is needed. The analysis of the results of our study reveals that women judge themselves too harshly. As the literature on PSA does not show great concern for gender issues, some tentative suggestions are proposed to support PSA with gender-awareness sessions.     

Teachers' memories of disciplinary control strategies from their own school days

This article provides a vision of school disciplinary strategies as provided by childhood school memories of practicing or unemployed teachers. This narrative approach allows us to understand the school and its daily routines and rituals from an insiders' point of view, drawing upon the double perspective teachers employ when reflecting on their own experience as school children. The results of the study demonstrate a wide range of disciplinary practices coinciding with a Foucauldian disciplinary structure – a system of micro‐penalty governing time, activity, behavior, speech, the body, and sexuality. Analyzing the systemic regulation of bodies in schools can uncover institutional meanings and make them available for questioning, perhaps even negotiation. Recognizing the ways in which teachers' roles are inextricably bound with the disciplinary power relations of their institutions can help alleviate frustration and burnout and help teachers make more informed pedagogical decisions.     

Nothing in the History of Spanish <Emphasis Type="Italic">Anís</Emphasis> Makes Sense,Except in the Light of Evolution

We describe, discuss and illustrate a metaphoric parallel between the history of the most famous Spanish liqueur, “Anís del Mono” (Anís of the Monkey), and the evolution of living organisms in the light of Darwinian theory and other biological hypotheses published subsequent to Charles Darwin’s Origin of Species. Also, we report the use of a caricature of a simian Darwin with a positive connotation, perhaps the only one ever produced. We conclude that, like some species in the natural world, Anís of the Monkey has evolved, adapted, survived and become the fittest and most successful anís in the Spanish market and possibly the world. We hope this paper will contribute a new useful metaphor for the teaching of biological evolution.     

Empathy and critical thinking: primary students solving local environmental problems through outdoor learning

The present study explores the outcomes of teaching empathy and critical thinking to solve environmental problems. This investigation was done throughout the duration of an environmental education course within a primary school located in central Chile. A community-based research methodology was used to understand the formation of empathy and critical thinking. The findings reveal a significant benefit in using empathy strategies to engage students regarding the thinking processes involved with solving environmental problems. Using these elements as teaching techniques for environmental education courses can be very helpful in reaching the aims of creating a sustainable citizenry.     

The Development,Implementation, and Evaluation of a Problem Solving Heuristic

Problem-solving is one of the main goals in science teaching and is something many students find difficult. This research reports on the development, implementation and evaluation of a problem-solving heuristic. This heuristic intends to help students to understand the steps involved in problem solving (metacognitive tool), and to provide them with an organized approach to tackling problems in a systematic way. This approach guides students by means of logical reasoning to make a qualitative representation of the solution of a problem before undertaking calculations, using a backwards strategy, which thus comprises a cognitive tool. The findings of the study suggest that students found the heuristic useful in setting up and solving quantitative chemical problems, and helped them to understand the phases of the problem solving process. Possible applications of the heuristic in the classroom include its use in formative assessment, to identify and to overcome student alternative conceptions, problem-solving in a cooperative environment, and to reduce the gender gap in science.
