Secondary School Students' Knowledge and Opinions on Astrobiology Topics and Related Social Issues.
2017
Astrobiology is the study of the origin of life on Earth and the distribution of life in the Universe. Its multidisciplinary approach, social and philosophical implications, and appeal within the discipline and beyond make astrobiology a uniquely qualified subject for general science education. In this study, student knowledge and opinions on astrobiology topics were investigated. Eighty-nine students in their last year of compulsory education (age 15) completed a written questionnaire that consisted of 10 open questions on the topic of astrobiology. The results indicate that students have significant difficulties understanding the origin of life on Earth, despite exposure to the topic by w…
Spatiotemporal Neurodynamics Underlying Internally and Externally Driven Temporal Prediction: A High Spatial Resolution ERP Study
2015
Abstract Temporal prediction (TP) is a flexible and dynamic cognitive ability. Depending on the internal or external nature of information exploited to generate TP, distinct cognitive and brain mechanisms are engaged with the same final goal of reducing uncertainty about the future. In this study, we investigated the specific brain mechanisms involved in internally and externally driven TP. To this end, we employed an experimental paradigm purposely designed to elicit and compare externally and internally driven TP and a combined approach based on the application of a distributed source reconstruction modeling on a high spatial resolution electrophysiological data array. Specific spatiotemp…
Identity development in German emerging adults: not an easy task.
2012
In this chapter, we review identity development in German youth as well as the impact of German cultural history on difficulties in developing a sense of national identity. Current socioeconomic and political contexts, such as instability of labor markets and prolonged transitions to work and partnership, are likely to affect identity development. Identity development is particularly challenging for young adults from immigrant backgrounds, from low socioeconomic brackets, or who suffer from chronic health conditions. In this context, we highlight the supportive role of social networks (parents, peers, and romantic partners) for identity development. Cross-cultural studies have suggested dis…
Impact of Low Maternal Education on Early Childhood Overweight and Obesity in Europe
2016
BackgroundComparable evidence on adiposity inequalities in early life is lacking across a range of European countries. This study investigates whether low maternal education is associated with overweight and obesity risk in children from distinct European settings during early childhood. MethodsProspective data of 45 413 children from 11 European cohorts were used. Children's height and weight obtained at ages 4-7 years were used to assess prevalent overweight and obesity according to the International Obesity Task Force definition. The Relative/Slope Indices of Inequality (RII/SII) were estimated within each cohort and by gender to investigate adiposity risk among children born to mothers …
The choice between retirement and bridge employment: a continuity theory and life course perspective.
2009
The rapid aging of the workforce in most developed countries, and the strengthening presence of bridge employment among older employees, has brought about a need for a deeper theoretical and practical understanding of this employment phenomenon. This study examined the concept of bridge employment from a continuity theory and life course perspective. Several personal and job-related antecedents of 539 middle-aged and older U.S. Federal Government employees' intentions of full retirement or engagement in bridge employment were investigated. A multinomial logistic regression analysis provided support for most of the hypotheses on the antecedents of full retirement and overall bridge employme…
Beyond islet trasplantation in diabetes cell terapy:from embryonic stem cells to transdifferentation of adult cells
2013
Exogenous insulin is, at the moment, the therapy of choice of diabetes, but does not allow tight regulation of glucose leading to long-term complications. Recently, pancreatic islet transplantation to reconstitute insulin-producing cells, has emerged as an alternative promising therapeutic approach. Unfortunately, the number of donor islets is too low compared with the high number of patients needing a transplantation leading to a search for renewable sources of high-quality -cells. This review, summarizes more recent promising approaches to the generation of new -cells from embryonic stem cells for transdifferentiation of adult cells, particularly a critical examination of the seminal work…
Radiological anatomy assessment of the fissura pterygomaxillaris for a surgical approach to ganglion pterygopalatinum
2017
The ganglion pterygopalatinum has become a therapeutic target to treat various pain syndromes in recent years. It is located in the fossa pterygopalatina, and the fissura pterygomaxillaris is the main access to surgically approach this structure. Recently, the neuromodulation of the ganglion pterygopalatinum by microstimulator implantation has become the first therapeutic line in refractory cluster headache treatment. This invasive technique is performed transorally through the fissura pterygomaxillaris, and is limited by the size of the implantation device, which requires an opening of at least 2 mm. Therefore, extensive knowledge about the anatomy of the fissura pterygomaxillaris prior to…
The Influence of University Students’ Stress Mindsets on Health and Performance Outcomes
2018
Background Emerging evidence indicates that holding particular stress mindsets has favorable implications for peoples’ health and performance under stress. Purpose The aim of the current study was to examine the processes by which implicit and explicit stress mindsets relate to health- and performance-related outcomes. Specifically, we propose a stress beliefs model in which somatic responses to stress and coping behaviors mediate the effect of stress mindsets on outcomes. Methods Undergraduate university students (N = 218, n = 144 females) aged 17– 25 years completed measures of stress mindset, physical and psychological wellbeing, perceived stress, perceived somatic responses to stress…
Strategies and Measurement Tools in Physical Activity Promotion Interventions in the University Setting: A Systematic Review
2020
The university environment is especially suitable for implementing health promotion interventions and specifically for physical activity promotion among university students. The objective of this systematic review was to describe the strategies employed and the physical activity data collection tools that have been used in said interventions. A systematic search for articles was conducted using the PubMED, Cochrane, and PEDro databases. The articles selected were those describing a physical activity promotion intervention aimed at university students in their own university setting in which there was a control group. Eventually, 1074 articles were identified, of which 13 fulfilled the selec…
Another look at safety climate and safety behavior: deepening the cognitive and social mediator mechanisms.
2012
WOS:000301081700053 (Nº de Acesso Web of Science) “Prémio Científico ISCTE-IUL 2013” In this study, safety climate literature and the theory of planned behavior were combined to explore the cognitive and social mechanisms that mediate the relationship between organizational safety climate and compliance and proactive safety behaviors. The sample consisted of 356 workers from a transportation organization. Using a multiple mediation design, the results revealed that proactive and compliance safety behaviors are explained by different patterns of combinations of individual and situational factors related to safety. On the one hand, the relationship between organizational safety climate and pr…
