The purpose of this study was to describe and compare cardiac structure and function in adult male weight trainers, runners, and those who do both activities. Subjects had actively participated in the various training programs for the previous five years. Age ranged from 28.4 to 31.3 years in the three groups. Echocardiography was used to assess selected heart diameters, volumes, indices of contractility, and thicknesses, while VO2 max and percent body fat were measured using standard methods. Heart structure and function were expressed in absolute terms and relative to total body weight. An alpha level of .05 was used in all comparisons. Results indicated the runners demonstrated significantly greater relative LVIDd, LVIDs, and LVPW than the weight trainers. The runner/weight trainers possessed significantly greater relative LVIDd, LVIDs, LVPW, IVS, and LVEDV than the weight trainers. No significant differences, absolute or relative, existed between the runner and runner/weight trainer groups in any of the myocardial structure and function variables. It was concluded that men who run or run and weight train have similar structural and functional characteristics of the heart and possess greater relative internal diameter and left ventricular wall thickness than men who only weight train.  相似文献   

THE PRO-EEC CONVERSION OF GREEK PUBLIC OPINION (1981-90)     

Dimitras  Panayote Elias 《Int. Journal of Public Opinion Research》1992,4(1):37-50

Greece became an EEC member in 1981, following a parliamentaryvote in the then New Democracy (conservative)–controlledparliament. Opinion polls indicated though that were a referendumheld at the time, membership would have been rejected, as thegovernment had lost its popular support (and lost power in thecourse of that year) and an across-the-board anti-western majorityhad emerged in a country whose people's national identity wasfirst defined during and as a defense against the crusades.Ten years later, there exists in Greece a very large consensusin favor of EEC membership which includes even the communistleft, at least programmatically. The spectacular, and unprecedentedamong Community countries, pro-EEC conversion is the subjectof this paper. First, using the European Commission's Eurobarometerand Eurodim's Helleno-barometer data, the evolution of Greekpublic opinion towards the EEC is documented. Secondly, thetrend data in the various voting groups show that this conversionis basically the result of the transformation of the socialistelectorate from anti-EEC to pro-EEC, but with a lag behind thesimilar change in the party's (PASOK) policies during its eight-yearrule (1981–9). Thirdly, evidence is provided that anti-westernismhas not died out in Greece, but that it has both mellowed andbecome ‘selective’. So, we conclude that the pro-EECconversion was not the result of some general ‘Westernization’of Greek public opinion, but the outcome of a ‘learningexperience’: during their country's ten-year EEC membership,the Greeks discovered that the benefits from this internationalcommitment far outweighed the costs. In fact, it is argued thatthe pro-EEC conversion of Greek public opinion has contributedto the mellowing of its anti-westernism: whereas the crusadeswere instrumental in cutting the Greeks from Europe, the EECappears now the vehicle of their reintegration into a worldin whose development they have historically played a major role.  相似文献

E-learning and Evaluation in Modern Educational System     

Tamara Tomasegovic Paula Yadranka Zitinski Elias Marina Baracic Nikola Mrvac 《美中教育评论》2011,(2):198-203

Implementation of information and communication technologies as well as emersion of new user interfaces and web 2.0 technologies changes the way of education system, the way of living and business transactions in general. The way we communicate, operate, produce and live is also changing. In accordance with it, the systems of education change from traditional to modern. The following changes occur： from content delivery to knowledge production, from transfer of knowledge from teachers to students towards encouragement of development and construction of knowledge, from courses and programs changing to the adaptation of the study environment, from the faculty professionalism to the quality of teaching and student learning and the early involvement of students in research work and projects. These occurring changes also affect the students＇ and professors＇ mobility. Here, the word ＂mobility＂ represents not only the student exchange programs and the easier transitions from one＇s home university to a foreign one, but also the way professors conduct their classes. With the development of certain software, students＇ class attendance no longer represents an important factor, as they can now learn from distance using the mentioned software, taking the learning process one step further. In order for above-mentioned changes to occur, the use of e-learning and the development of new tools are almost mandatory. With this in mind, the goal of this paper is to analyze quantitatively the changes that are occurring almost every day that affect the students＇ learning and the professors＇ teaching methods.  相似文献   

Personalised news and scientific literature aggregation     

Nikolaos Nanas  Manolis Vavalis  Elias Houstis 《Information processing & management》2010

Content-based filtering can be deployed for personalised information dissemination on the web, but this is a possibility that has been largely ignored. Nowadays, there are no successful content-based filtering applications available online. Nootropia is an immune-inspired user profiling model for content-based filtering. It has the advantageous property to be able to represent a user’s multiple interests and adapt to a variety of changes in them. In this paper we describe our early efforts to develop real world personalisation services based on Nootropia. We present, the architecture, implementation, usage and evaluation of the personalised news and paper aggregator, which aggregates news and papers that are relevant to an individual’s interests. Our user study shows that Nootropia can effectively learn a user’s interests and identify relevant information. It also indicates that information filtering is a complicated task with many factors affecting its successful application in a real situation.  相似文献

Holding the Line: Sustaining an SEL-Driven Whole-School Approach in a Time of Transition     

Jonathan Kasler  Maurice J. Elias 《Journal of educational and psychological consultation》2013,23(3):227-246

Recently, a growing body of research has focused on the sustainability of evidence-based interventions aimed at promoting the social emotional and character development of children (SEL) and preventing or reducing problem behaviors in schools. Current discussions of systemic reform in the education system address the capacity of individual schools to adopt innovations and maintain them despite inevitable environmental changes. A small elementary school in northern Israel embarked on a radical change in its pedagogic style, intentionally adopting a holistic SEL approach. After 3 intensive years of training and implementation supported by the local community and involving all major stakeholders, a series of events threatened to weaken the chances of sustaining the approach. In a qualitative research study, data were collected primarily through in-depth interviews with full-time faculty members. Constant comparison analyses were performed. The results illustrate the salient concerns and benefits of attempting such a radical change through the eyes of the faculty members. The depth of identification with SEL among faculty and other stakeholders is shown to be the basis for sustaining the SEL approach in spite of difficulties. This narrative of events demonstrates the obstacles encountered on the road to approach sustainability. This identification of possible challenges is valuable to those introducing change in the school environment.  相似文献   

Inclusion in action: an in-depth case study of an effective inclusive secondary school in the south-west of England     

Elias Avramidis  Phil Bayliss  Robert Burden 《International Journal of Inclusive Education》2013,17(2):143-163

This paper represents the outcomes of an in-depth case study of a secondary school in the south-west of England, identified as inclusive by the local education authority (LEA). The study, which formed the second part of a ‘bricolage’ approach, utilized ethnographic research methods, with the aim of investigating inclusion in a holistic way, at the school level. Data were collected through interviewing of a variety of school constituencies and participant observation. The analysis suggested that: (a) the participants were enculturated into the integration model; (b) although there were strong perceived academic benefits for the included students, the evidence is contradictory regarding the social outcomes of inclusion; (c) successful implementation of inclusion requires restructuring of the physical environment, resources, organizational changes and instructional adaptations; and (d) there was a perceived need for ongoing professional development. The findings reported in this investigation may be used to illuminate current practice in the LEA and to provide directions for formulating policies to support ‘inclusive practice’ in ways which are acceptable to teachers, parents and students.  相似文献   

Special education in Pakistan     

Sophia Mavropoulou  Elias Avramidis 《欧洲特需教育杂志》2013,28(3):337-353

The aim of this research was to examine the type of activities as well as the challenges faced by befrienders supporting persons with autism spectrum disorders (ASD). Twenty-nine volunteers befriending an equal number of families with children with ASD participated in this study. Content analysis was applied on visit logs (n = 465) completed by befrienders during a nine month period, supplemented by thematically analysed evidence derived from semi-structured interviews with befrienders at the end of their volunteering experience. In agreement with our expectations, findings indicate a variation in the type, number and location of activities as well as the challenges of befrienders, depending on the level of ability of persons with ASD. Befrienders in both groups were mostly involved in leisure activities, had greater social interaction with the high functioning autistic group and carried out more structured 1:1 activities with individuas with low functioning autism. Interestingly, befrienders in both groups did not differ significantly on their reported challenges. The implications of this befriending service as a means of social support for families with persons with ASD are discussed.  相似文献   

Two decades of curricular reforms in the Spanish university     

Helena Troiano  Josep M. Masjuan  Marina Elias 《International Studies in Sociology of Education》2013,23(3):211-230

In this article we present the topic of the orientation of university curricula, the pressures that exist today as a response to the demands of the market, and we examine specifically the transformation that has developed in Spain during the last two decades. We have tried to base the statements and analyses that are presented on empirical data obtained from our own research (Education and Labour Research Group—GRET). The motivation to write this document has been to try to add to the debate about the changes experienced by the university, in particular in regards to the curriculum, and to reflect on our experience as investigators in higher education.  相似文献
