Abstract
Recent evidence suggest that massive amount of practice of a skill results in the development of a specific memory representation that is distinguished by its enhanced performance capability relative to the other members of the same class that is uniqe and termed 'Especial Skill'. This study aimed to investigate the emergence of special skill and reevaluation the visual-context hypothesis using badminton players in three skill levels (expert, skilled, less-experienced). Subjects (10 players in each group, mean age=23.12 ±3.85 years) performered 100 backhand short serves at five distances (1.5, 2, 2.5, 3, 3.5 meters from net) in each of environmental conditions (normal and covered court). The regression analyze showed that accuracy in skilled group at 2 meters distance was significantly better than predicted by regression equation, supporting the especial Skill effect, but it wasn’t showed in two other groups. This specific advantage of practice at this point was not emerged at absence of visual cues that supported the visual-context hypothesis.

Abstract
Today, the organizational culture variable is the main focus of analysis in many organizational studies. In the last years, this construct, has found special status in the field of sport management researches. This study aims to validate and investigate the psychometric properties of organizational culture assessment instrument (OCAI) based on the competing values framework model (CVF) in Iranian sport organizations (federations). The methodology of the present research is based on a correlation study (A factor analysis type of covariant matrix or correlation through principle components analysis method). The statistical population includes 52 sport federations (703 sport experts). In confirmatory factor analysis (CFA) method, the number of samples was determined according to the number of variables and 253 subjects (83.77%) were selected in a stratified random sampling method as final samples. The data were collected through OCAI and the construct validity, also, analyzed using LISREL 8.70 software and a CFA method. The results obtained showed that OCAI questionnaire was a multi-dimensional construct and the four OCAI factors were confirmed to be as cultural profiles: Clan (6 items), Adhocracy (6 items), Market (6 items) and Hierarchy (6 items). The other result, confirmed the OCAI reliability suitability by computing internal consistency through cronbach &alpha test (r=0/86). Considering the confirmation of psychometric properties of OCAI and cultural profiles in factor analysis, organizational culture assessment instrument (OCAI) based on the competing values framework model (CVF) seems to be an appropriate instrument and theoretical framework for assessing the organizational culture in Iranian sports organizations (federations). Therefore, it is suggested that sport management researchers attempt to assess the organizational culture by using OCAI questionnaire in Iranian sport organizations.

Abstract
The purpose of this study was to investigate the relationship among servant leadership, team effectiveness, and team performance of the Iranian men's volleyball pro-league teams. Descriptive co-relational used as a research design. The statistical sample included players (n=173) and assistant coaches (n=66) from 15 teams. The data collected were gathered using two instruments: (a) The Organizational Leadership Assessment for Sports Teams that adjusted by researcher from The Organizational Leadership Assessment (Laub, 1999), (b) Team Excellence Survey (Larson & LaFasto, 1989). By conducting a confirmatory factor analysis (CFA), all agent factors of two instruments were identified. Pearson, and Spearman correlation, t-test, simple, and multiple regressions were used for data analyzing. The results showed that players' perceptions of servant leadership were moderate and assistant coaches' perceptions of servant leadership were excellent. There was a statistically significant and positive correlation among servant leadership, team effectiveness, and team performance. In addition, servant leadership was a significant predictor for team effectiveness and team performance. The results of this study supported the application of servant leadership in professional sports.

Abstract
This study aimed to address agreement level of performances on 3 selected motor skill assessment tools in a sample of Iranian first to fourth graders aged 7-10 year olds. The convenience sample included 164 healthy girls from public schools. A Pearson correlation coefficient was calculated on the association between MABC-2, KTK and TGMD-3 performances in graders. A one-way multivariate analysis of variance (MANOVA) was conducted to compare performances means across grade levels. Low-to-moderate correlations were found between assessments across age in each assessment. In general, girls demonstrated higher scores across age cohorts. In conclusion, low-to-moderate associations among assessments instruments provide different pictures/levels of motor competency and should not be used interchangeably in studies.
