Gross motor ability of native Greek, Roma, and Roma immigrant school-age children in Greece

The purpose of this study was to estimate and compare gross motor ability of children aged 7 to 10 years, all from Roma minority families (Romas, Roma immigrants) and families of indigenous Greeks. The sample consisted of 180 hildren (60 natives, 60 Romas, 60 Roma immigrants) studying in Greek public primary schools. The Test of Gross Motor Development scores showed that the group of indigenous Greek children had significantly higher performance in terms of locomotion skills, handling skills, and general motor ability compared to the groups of Roma and Roma immigrant children. No statistically significant differences were observed between the two other groups. These findings might be attributed to less participation of minority children in organized physical activities in and outside school, as well as to the reduced parental encouragement for attending related activities.     

An evolutionary system for neural logic networks using genetic programming and indirect encoding

Nowadays, intelligent connectionist systems such as artificial neural networks have been proved very powerful in a wide area of applications. Consequently, the ability to interpret their structure was always a desirable feature for experts. In this field, the neural logic networks (NLN) by their definition are able to represent complex human logic and provide knowledge discovery. However, under contemporary methodologies, the training of these networks may often result in non-comprehensible or poorly designed structures. In this work, we propose an evolutionary system that uses current advances in genetic programming that overcome these drawbacks and produces neural logic networks that can be arbitrarily connected and are easily interpretable into expert rules. To accomplish this task, we guide the genetic programming process using a context-free grammar and we encode indirectly the neural logic networks into the genetic programming individuals. We test the proposed system in two problems of medical diagnosis. Our results are examined both in terms of the solution interpretability that can lead in knowledge discovery, and in terms of the achieved accuracy. We draw conclusions about the effectiveness of the system and we propose further research directions.     

Construct validity of the self-assessment evaluation form for the Olympic Education Training Program in Greece

The Professional Development Evaluation Form, developed to evaluate training of physical education teachers for the Olympic education program in Greece, was administered to 438 physical educators (205 men and 233 women; M age=32.2 yr., SD= 9.1). A confirmatory factor analysis indicated an adequate fit of the proposed model.     

Evaluating the impact of human rights education on the adjustment of Greek primary school students

Human rights education has an encouraging effect on children's school routine. The aim of the present study was to investigate the effectiveness of a 12-session transformative human rights education intervention in improving children's school adjustment. Participants were 340 Greek primary school students assigned to intervention group (n = 187) and control group (n = 153). All members completed a written questionnaire 1 week before the implementation of the intervention, measuring their knowledge of human rights, school engagement, perceptions of the school environment, interpersonal relationships, empathy and perceptions, attitudes and feelings towards school. The completion process of the same questionnaire was repeated 1 week after the termination of the intervention and 4 months later. The results showed that the intervention was particularly beneficial as the intervention group members demonstrated a significant increase in their knowledge of human rights, school engagement, perceptions of the school environment, empathy and school liking, while experiencing a significant decrease in school avoidance and loneliness. Members of the control group did not report any significant improvement over time. The study's implications for future research on school-based human rights interventions are discussed.     

Religiosity and psychological well-being

The aim of the present study was to investigate the relationship between religiosity and psychological well-being in a sample of Greek Orthodox Christians. Previous research has documented that personal devotion, participation in religious activities, and religious salience are positively associated with different criteria of psychological well-being. The sample (83 men and 280 women) with an age range from 18 to 48 years, was strongly skewed with respect to sex (77% female) and education level (95% were university students or university graduates). Religiosity was operationalized as church attendance, frequency of prayer and belief salience. In addition, a single item referring to beliefs about God was used. Depression, anxiety, loneliness, and general life satisfaction were selected as dependent variables because they reflect important dimensions of psychological well-being. Preliminary analyses showed that sex was significantly related to the three religiosity variables (church attendance, frequency of prayer, belief salience), with women being more religious than men. Consistent with previous research, correlations suggested that church attendance and belief salience were associated with better life satisfaction. The results of hierarchical regression analysis showed a significant positive association between anxiety and frequency of personal prayer. Finally, personal beliefs about God did not seem to relate to any of the psychological well-being measures. The results of the present study partially support the hypothesized association between religiosity and psychological well-being.     

Orthodox Anti-Westernism Today: A Hindrance to European Integration?

Anti-Westernism is a widespread phenomenon in the Orthodox world today, particularly in Eastern and South-Eastern Europe, expressed by numerous actors, manifested at various levels and operating in different contexts, religious and otherwise. Historically it can be traced back to the long-term differentiation between the Eastern Roman (Byzantine) and the Western Roman Empire, as well as between the Roman Catholic Church and the Eastern Orthodox Patriarchates. Because many Orthodox earlier used to identify Europe with the West, anti-Westernism is sometimes closely connected with anti-Europeanism. Drawing examples mostly from the Greek and Russian cases, this paper attempts to assess Orthodox anti-Westernism in its contemporary dimensions by pointing to its numerous antinomical manifestations, which can hardly render it an obstacle and a threat to European integration today.     

Laboratory strength measures of talented and less talented Greek children ages 9 to 10 years

The purpose was twofold: (1) to assess whether laboratory tests can distinguish talented groups and less talented groups of children identified by their total scores in a battery of field tests and (2) to evaluate whether scores in field and laboratory tests are correlated. 36 children (ages 9 to 10 years) were divided into groups of higher and lower total scores on standing long jump, medicine ball throw, and sprint. Both groups were tested for maximum isometric force, force produced at the initial 100 msec., reactive force index, drop jump height, squat jump height, and maximum pedaling rate. Analysis showed the talented group had significantly (p < or = .05) higher scores on maximum isometric force, force produced in the initial 100 msec., and drop jump height than less talented children. Moderate to high correlations were found among scores for field performance tests with maximum pedaling rate. In conclusion, the laboratory tests distinguished the talented and less talented children in maximal isometric force, the force produced at the initial 100 msec., the reactive force index, and the drop jump height.     

Modeling sport services in Greece: a re-evaluation of outcome dimension

The Service Quality Scale, developed to evaluate perceived service quality in sport services in Greece, was administrated to 389 participants, 208 men and 181 women. Their mean age was 36.4 yr. (SD = 8.7). A confirmatory factor analysis did not support the prior five-factor solution. When the outcome dimension was removed, a four-factor model appeared an adequate fit. Practical implications are discussed.     

The Church of Greece in critical times: reflections through philanthropy

In this article we reflect on the position and role of the Orthodox Church of Greece in contemporary Greek society as the latter is ravaged by a multi-layered crisis. This we do through the study of the discursive prerequisites and underlying logic governing the philanthropic response of the Church to the crisis, as promulgated by the Church’s major institutional settings, the Synodical Committee on Social Welfare and Beneficence and the Archdiocesan Anti-Poverty Fund. Viewing the Church and the state as uneasy partners in the process of the modernisation of Greece, we first consider the Church’s understanding of the crisis before focusing on the way this informs the practice of the above-mentioned institutional settings. We conclude with some thoughts on the Church’s attempt to transcend the secular–religious divide through imbuing its philanthropic praxis with its transcendental Christian hope.
