The sample consisted of 175 physical education teachers, from primary and secondary education. The Maslach Burnout Inventory (Maslach and Jackson, 1986) and the Employee Satis faction Inventory (Koustelios and Bagiatis, 1997) used to assess burnout and job satis faction respectively. Canonical correlation analysis revealed a negative multivariate relationship between the two constructs ( rc=.61). Canonical loadings indicate that job satisfaction is primarily affected by ‘job itself’ followed by ‘supervision’ and ‘working conditions’, whereas burnout is affected by ‘personal accomplishment’ and ‘emotional exhaustion’. Intrinsic aspects of job satisfaction seemed to correlate stronger to burnout than the extrinsic.

In particular, it was examined the mediating role of self-esteem on the relation of extraversion, neuroticism and happiness. In the study participated 207 Greek adults aged 25-60 years old. Three different questionnaires were administered to all participants: the Oxford Happiness Questionnaire (OHQ), the Eysenck Personality Questionnaire Revised-Abbreviated (EPQR-A) and the Rosenberg Self-esteem Scale (RSE). Results indicated that the three constructs (self-esteem and two personality traits) jointly explained the 67 % of happiness variability. Happiness is best predicted by self-esteem, following by neuroticism (negatively) and extraversion (positively). Moreover, structural equation model (SEM) analysis showed that self-esteem only partially mediated the effects of both extroversion and neuroticism on self-report happiness.

Seventy-three educators (23 pre-school teachers, 30 primary school teachers and 20 primary physical education teachers) participated in the study assessing 584 students (age range 5–12 years, 292 boys & 292 girls), covering the total of age range addressed by the MABCC-2. Students were assessed both by the MABCC-2 and the Movement Assessment Battery for Children2 motor test (MABC-2-T). Concurrent validity was investigated by measuring the level of agreement (Kappa coefficient) between the checklist and the motor test, as well as by calculating the sensitivity, specificity and accuracy rates. Results revealed a moderate value of agreement (k=.28), moderate sensitivity (50.6%) and acceptable specificity (80.7%). The type of educator displayed a significant ef...

Three hundred twelve students from 14 universities (95 women and 217 men) with a mean age of 21.0 years (SD = 1.9) participated in the study. The Target Population Satisfaction Index (TPSI) was used to measure effectiveness in campus recreation programs. To measure participants’ satisfaction, the Athlete Satisfaction Questionnaire (ASQ) was used. Results indicated that the two questionnaires are valid and reliable instruments and can be used in measuring effectiveness in campus recreation programs in Greece. Canonical correlation analysis showed that the two factors from the TPSI were positively and significantly associated with the five dimensions of the ASQ.

The purpose of this study was to examine the effect of CLA supplementation to humans on body fat, certain biochemical parameters of serum, and the CLA content of serum lipids. Twenty-two volunteers were divided into a study group and a control group in a doubly blind design. The study group received 0.7 g of CLA for four weeks and 1.4 g of CLA for the next four weeks, while the control group received placebo. Diet was controlled and no significant differences in energy or macronutrient intake were found between the two groups. Measurements were taken at baseline, four weeks, and eight weeks. The sum of the thickness of ten skinfolds, percentage body fat calculated from it and fat mass was significantly reduced in the CLA group during the second period (P < 0.004) but not overall during the study. Serum HDL-cholesterol decreased significantly (P < 0.001) and triacylglycerols as well as total cholesterol tended to decrease in the CLA group during the first period. The CLA content of serum non-esterified fatty acids, triacylglycerols, phospholipids, and cholesteryl esters increased gradually with supplementation; the CLA content of total serum lipids doubled at the end of the study compared to baseline. Phospholipids had the highest CLA content regardless of supplementation. These data indicate that supplementation with 0.7-1.4 g CLA daily for 4-8 weeks may modulate body fat and serum lipids, as well as increase the CLA content of serum lipids in humans.

However, limited attention has been devoted to the consequences of distant (i.e., foreign) team identification. The purpose of the current research was to examine the way in which fans (local and distant) can increase their levels of collective and personal self-esteem due to their team identification.Design/methodology/approachData were accumulated from three Greek websites (N = 742). Among them, 623 subjects were grouped as local and 119 as distant football fans. A structural invariance analysis was followed.FindingsThe results revealed how team identification, enduring team-related social connections, and basking in reflected glory are interrelated to affect collective and finally personal self-esteem. Moreover, no differences were found between local and distant fans regarding the paths from eam identification to collective self-esteem and from collec...
