Associations Between Built Environment Characteristics and Walking in Older Adults in a High-Density City: A Study From a Chinese Megacity
2020
The built environment is an important factor affecting physical activity, especially walkability. Walkability is used to characterize the user friendliness of outdoor physical activity. However, studies on walkability and physical activity are mainly concentrated on low-density Western cities. Study on the walkability of high-density cities in Asia, especially with the elderly, is seriously lacking. And walkability is often used as a composite indicator. This study mainly re-examines the relationship between the common indicators of walkability (population density, street connectivity, land-use mix, and retail density), transport-related walking, and leisure-time walking with older adults i…
Comparative analysis of short tandem repeats and single nucleotide polymorphisms on the Y-chromosome in Germans, Chinese and Thais.
2003
We have typed genomic DNA samples from 95 individuals from Western Germany, 78 individuals from Bangkok/Thailand and 56 individuals from Chengdu/China for 11 Y-chromosomal diallelic polymorphisms and eight short tandem repeat (STR) systems. For single nucleotide polymorphism (SNP) analysis, a rapid method was applied using the single base extension technology (minisequencing) in combination with capillary electrophoresis. PCR products for SRY-8299, Tat, SRY2627, 92R7, SRY1532, M9, M13, M17/M19 and M20 were pooled and used as templates for the commercially available SNaPshot kit. In addition to these ten SNPs we also tested the Y-chromosomal diallelic Alu repeat insertion DYS287 (YAP) by aga…
A Systematic Umbrella Review on the Epidemiology of Modifiable Health Influencing Factors and on Health Promoting Interventions Among University Stud…
2020
Background: Universities represent an important setting for health promotion. The unique collective of university students is of particular relevance since they are the leaders, decision-makers, and parents of tomorrow. In this context, modifiable health influencing factors as well as interventions to prevent these, play a crucial role. Therefore, the present umbrella review aims to (i) provide an overview of review articles addressing epidemiological issues (prevalence and determinants) of modifiable health influencing factors in university students and (ii) to provide an overview of review articles addressing the evidence of interventions to promote/enhance modifiable health influencing f…
Un estudio del contenido científico de las preguntas formuladas por estudiantes cuando intentan comprender dispositivos experimentales
2013
RESUMEN: Se muestra un análisis descriptivo del contenido científico de las preguntas formuladas por estudiantes de secundaria y universitarios, cuando tratan de comprender el funcionamiento de dispositivos experimentales. Se consideran tres situaciones didácticas habituales: leer un texto acompañado de imágenes estáticas (esquemáticas); visualizar imágenes dinámicas (video o demostración de cátedra), observar y manipular los dispositivos. Solo una tercera parte de las preguntas de los estudiantes contuvieron algún término científico, aunque los universitarios superaron claramente a los de secundaria. Las leyes y principios científicos, necesarios para modelizar y explicar la realidad, apen…
Actitud hacia la financiación pública de la ciencia. Un estudio comparativo en el contexto iberoamericano
2013
El apoyo a la financiación pública de la ciencia refleja una actitud positiva hacia esta, y para comprenderla, es importante tener en cuenta el contexto social y cultural en el que los ciudadanos interaccionan con la ciencia. Por tanto, los objetivos del trabajo son: 1) analizar la relación entre apoyo a la financiación pública de la ciencia y la percepción social de esta actividad para identificar a quienes muestran una actitud positiva, y 2) analizar las diferencias debidas al contexto. Del análisis multivariante de los datos de la encuesta del Proyecto de Estándar Iberoamericano de Indicadores de Percepción Pública, Cultura Científica y Participación Ciudadana (2005-2009), realizada en s…
Darwin como noticia. La imagen de Darwin a través de los medios de comunicación en el bicentenario de su nacimiento
2009
This paper analyzes Darwin's image as presented by the mass media on the day his bicentennial was celebrated. The headlines that included the term (keyword) 'Darwin' published on February 12, 2009 were selected from a database of on-line media. The content analysis of those texts shows that, aside from the anecdotic stories directly related to the commemoration of the bicentennial of his birth, Darwinism's 'newsworthy hook' continues to center on the debate between science and religion as cultural authorities. In contrast, Darwin's contributions to the understanding of the process of evolution, his impact on the whole of the biological sciences, or the current debates related to biological …
A actual crise planetária. Uma dimensão esquecida na educação em ciência
2004
Afinalidade da presente investigação foi analisar qual o possível contributo da Educação em Ciência na clarificação e compreensão pública dos problemas e desafios relacionados com o futuro do nosso planeta. Iniciámos o trabalho procurando o contributo de diferentes estudos elaborados numa perspectiva holística, tendo como objectivo principal elaborar uma visão global do estado do planeta Terra e estudar as possíveis causas e soluções para os problemas identificados. Posteriormente analisámos as percepções de professores de ciências, 327 'em serviço' e 521 'em formação' de Espanha, Portugal e América Latina. Analisámos, ainda, o conteúdo de 127 manuais escolares referentes ao ensino secundár…
Climate change reshuffles northern species within their niches
2022
Climate change is a pervasive threat to biodiversity. While range shifts are a known consequence of climate warming contributing to regional community change, less is known about how species' positions shift within their climatic niches. Furthermore, whether the relative importance of different climatic variables prompting such shifts varies with changing climate remains unclear. Here we analysed four decades of data for 1,478 species of birds, mammals, butterflies, moths, plants and phytoplankton along a 1,200 km high latitudinal gradient. The relative importance of climatic drivers varied non-uniformly with progressing climate change. While species turnover among decades was limited, the …
Ethical Coffee Room: An international collaboration in learning ethics digitally.
2020
Background: Ethics is a fundamental part of health care professionals’ competence and one of the major quality factors in good nursing care. Research shows challenges in learning and applying ethics. Ethical Coffee Room (ECR) is an electronic platform, where the students, nurses and teachers discuss anonymously ethical issues during students’ clinical practice. ECR offers 1 credit (27 working hours) for the students. This work included reading theoretical material, contributions for discussion of ethical dilemmas and reflection of one’s own learning. Every user – student, nurse supervisor or teacher – could choose her or his own pseudonym. Aim: The aim of this study was to describe how nurs…
A blended-learning programme regarding professional ethics in physiotherapy students.
2018
Background: In the university context, assessing students’ attitude, knowledge and opinions when applying an innovative methodological approach to teach professional ethics becomes fundamental to know if the used approach is enough motivating for students. Research objective: To assess the effect of a blended-learning model, based on professional ethics and related to clinical practices, on physiotherapy students’ attitude, knowledge and opinions towards learning professional ethics. Research design and participants: A simple-blind clinical trial was performed (NLM identifier NCT03241693) (control group, n = 64; experimental group, n = 65). Both groups followed clinical practices for 8 mont…
