The effects of exercise in hypoxic and normoxic conditions on endothelin-1 and arterial compliance     

Giles LV  Warburton DE  Esch BT  Fedoruk MN  Rupert JL  Taunton JE 《Journal of sports sciences》2012,30(3):261-267

The purpose of this study was to determine the effects of short-term normoxic and hypoxic exercise on plasma endothelin-1 and nitric oxide levels, and the relationship of arterial compliance and pulmonary artery pressure to endothelin-1. Seven endurance-trained males completed two incremental and two steady-state exercise tests performed at ventilatory threshold in normoxia and hypoxia (fraction of inspired oxygen = 0.14). Plasma endothelin-1was measured throughout steady-state tests. Arterial compliance using applanation tonometry, plasma nitric oxide and pulmonary artery pressure using Doppler echocardiography were measured before and after exercise. Small arterial compliance and pulmonary artery pressure significantly increased following exercise. There were no main effects of condition or time for plasma endothelin-1and nitric oxide levels. There were no significant relationships between plasma endothelin-1 and arterial compliance or pulmonary artery pressure. In conclusion, mechanisms other than the endothelial system may play a role in the exercise-induced changes in small artery compliance in this study population. Moderate hypoxia and a 30-minute steady-state exercise have limited effects on plasma endothelin-1 in endurance-trained males.  相似文献   

Web technologies applied to virtual heritage: An example of an Iberian Art Museum     

María Dolores Robles-Ortega  Francisco R. Feito  Juan J. Jiménez  Rafael J. Segura 《Journal of Cultural Heritage》2012,13(3):326-331

Nowadays, some virtual museums include 3D room scenes to show the models of its pieces, just like in real museums. Nevertheless, the generation and maintenance of this kind of scenes is generally difficult and should be done by an expert. For example, any change such as including a new piece or modifying the position of an existing fragment usually requires a different design and the creation of a new scene. In this paper we present a case study on the development of a web-based application to automatize this process. To this end, a database to store both graphic and non-graphic information about the pieces, and some 3D rooms to show them has been created. The designed scenes only contain some pieces of furniture to exhibit the fragments, which will be subsequently included. Thus, when a room is loaded in the web page, its associated pieces are obtained through a query in the database and its models are dynamically included in the original scene. Therefore, the position changes or the inclusion of new pieces are not performed in the 3D model, but in the database. Our application makes the transmission of the knowledge to the general public easier because any new discovered piece can be included in a existing museum effortlessly.  相似文献   

The Staff Conference: A Medium for Staff Development     

Jim Jones Deputy Headmaster 《School Leadership & Management》2013,33(2):131-134

Solihull's development of delegated budgets began in 1981. The experiences of schools and Centre led to the acceptance by Council in 1987 of a scheme for general implementation. The detailed scheme is included in an Appendix to the article, together with examples of vital financial management systems. In his article, the Director of Education explores the effects of delegation of the budget, and with it, the decision‐making process. The school heads’ role gains the natural extension of facility to implement management decisions, but what of the role of the Centre?  相似文献   

The construction of a questionnaire to evaluate the science orientedness of students' identities as learners from a cognitive perspective     

Ruurd Taconis  Lesley G.M. de Putter-Smits  Steven Henry  Perry J. den Brok  Douwe Beijaard 《Educational Research and Evaluation》2013,19(4):383-400

Forming a science-oriented identity is considered a process underlying both interest and achievement in science education. A questionnaire is developed for describing “identities as learners” and evaluating their science orientedness. The instrument (k = 65) focuses on cognitive aspects. An internal coherence of .88 was found. Five subscales were defined that proved interrelated yet distinguishable. A pilot amongst 40 students from Dutch general secondary education showed that preferring science over non-science subjects and relatively high grades for sciences subjects were strongly correlated to science orientedness of the learner identity (r_s  = .65; p < .001). The results support the reliability and validity of the questionnaire but also point to the importance of identity as a central concept in studying science education. It is concluded that we made a promising step in constructing an instrument for monitoring the development of cognitive aspects of science-oriented identities during (innovative) science education.  相似文献   

Teacher educators’ collaboration in subject departments: collaborative activities and social relations     

Henderijn Heldens  Anouke Bakx  Perry den Brok 《Educational Research and Evaluation》2013,19(7-8):515-536

Teacher educators’ collaboration plays an important role in the improvement of teacher education. Many studies in educational research focus on collaboration from 1 particular perspective. A focus on 2 perspectives, a qualitative (focusing on collaborative activities) as well as a quantitative (focusing on relations) perspective, and relating both perspectives, can add to our knowledge. Data were collected in 3 subject departments of a teacher education institute. Findings indicated that educators’ collaborative networks inside the departments could gain from more coherent and dense relations, and that key players were important to support and sustain collaboration. Both perspectives were mildly related, correlations were found for “degree” and “information” (r = .31, p < .05), “degree” and “joint work” (r = .38, p < .01), and “reciprocity” and “joint work” (r = .33, p < .05), no correlations were found for “degree” or “reciprocity” and “discussing”. At the department level, only mathematics showed significant correlations. Results indicated that, in further research, qualitative aspects as well as quantitative aspects should be included.  相似文献   

The influence of personality in determining farmer responsiveness to risk     

Dr. Marilyn Shrapnel  Dr. Jim Davie 《The Journal of Agricultural Education and Extension》2013,19(3):167-178

Abstract

Rural landholders are undergoing extended economic hardship, manifested in a range of social and ecological problems that limit the capacity of local areas to recover to economic levels necessary to sustain settlement. The uncertain influence of climate on production represents just one of the range of risk factors that landholders must face. Survival depends on the capacity of landholders to respond strategically to the stress which these risk factors generate. Our research indicates landholders’ capacity to modify land‐management practices, are dictated by their underlying personality traits and by presence or absence of other psychiatric morbidity. Where stresses exist, the capacity of people to respond actively to a planned problem solution diminishes. The psychological profiles of people tend to fall into three groups ‐ those who can generally cope; those who can usually cope but undergo dysfunctional episodes under acute stresses, and those who generally cannot cope.

In the grazing lands of central western Queensland, our findings suggest a predominant personality profile consistent with an ability to cope with isolation and the other particular challenges that characterise this way of life. There are two important implications in these results. The first relates to land stewardship and has significant lessons for government intervention in terms of rural policy and approaches to extension. In particular, there are lessons pertinent to the success of Landcare and associated community based initiatives. The second relates to the broad area of rural health as highlighted by the alarming rates of suicide found in rural Australia. In previous decades, those with personality styles less well‐suited to this industry, found employment in nearby rural towns. This option has declined as government policy has favoured the withdrawal of services and resources, hastening depopulation of rural areas. The resultant weakening of the social fabric of rural society is a cause of tension and stress with serious health implications. Previous approaches to rural sociology have not emphasised individual personality traits in seeking to understand the complexity of the human‐environment relationships which determine land use. Nor has personality been invoked is assessing the potential of landholders to adopt ecologically sustainable practices. Further research is planned to consolidate our findings through comparative investigations in other branches of rural industry. JAgr Educ Ext (2001, 7, 3, pp 167–178)  相似文献

De la ciudad aislada a la aldea global: El microordenador como catalizador del aprendizaje cooperativo y del intercambio cultural     

Jim Cummins 《Cultura y Educación》2013,25(1):57-70

Hace ya algunos años Cole y Scribner, con una investigación transcultural que se ha hecho clásica, establecían una distinción clave entre la lecto-escritura como código por una parte y los usos concretos que de ella se hace, por otra. Con el ordenador en la educación ha llegado también el momento de hablar quizá menos del aparato en sí y más de los usos psico-educativos que hacemos de él. En este artículo se analizan los usos del ordenador en la escuela y las implicaciones psicopedagógicas de esos usos, y se plantea también la materialización de la profecía McLuhiana de la aldea global y del aula sin muros. Por primera vez el aula puede cubrir todo el globo y conectar telemáticamente a niños de todas las culturas.  相似文献
