Research has found that, controlling for team quality, National Basketball Association visiting teams win more often when playing to the east of their home time zones and less often when playing to the west. We reaffirm this finding for 1991-2002. We find that only these seasons’ day games, and not their far more frequent night games, featured a significant relationship between time zone and visiting team win probability. We hypothesize that some of these day-game effects were biological in origin. The 2002-2013 seasons featured no significant relationship between time zones and visiting team win probability for either day or night games.

Team Heterogeneity

This paper started with theories of team heterogeneity and team performance, according to questionnaire survey method, reviewed three dimensions of knowledge heterogeneity (speciality heterogeneity, education heterogeneity and work experience heterogeneity) and their effects on team performance. The result showed that speciality heterogeneity was positively related to task performance and contextual performance, while work experience heterogeneity was positively related to contextual performance significantly, but had no significant relationship with task performance. In addition, education heterogeneity had no significant relationship with task performance and contextual performance.

Purpose:The effect of travel on athletic performance has been investigated in previous studies. The purpose of this study was to investigate this effect on game outcome over 10 Major League Baseball (MLB) seasons.Methods:Using the convention that for every time zone crossed, synchronization requires 1 d, teams were assigned a daily number indicating the number of days away from circadian resynchronization. With these values, wins and losses for all games could be analyzed based on circadian values.Results:19,079 of the 24,121 games (79.1%) were played between teams at an equal circadian time. The remaining 5,042 games consisted of teams playing at different circadian times. The team with the circadian advantage won 2,620 games (52.0%, P = .005), a winning percentage that exceeded chance but was a smaller effect than home field advantage (53.7%, P < .0001). When teams held a 1-h circadian advantage, winning percentage was 51.7% (1,903–1,781). Winning percentage with a 2-h advantage was 51.8% (620–578) but increased to 60.6% (97–63) with a 3-h advantage (3-h advantage > 2-hadvantage = 1-h advantage, P = .036). Direction of advantage showed teams traveling from Western time zones to Eastern time zones were more likely to win (winning percentage = .530) than teams traveling from Eastern time zones to Western time zones (winning percentage = .509) with a winning odds 1.14 (P = .027).Conclusion:These results suggest that in the same way home field advantage influences likelihood of success, so too does the magnitude and direction of circadian advantage. Teams with greater circadian advantage were more likely to win.

Executive Positions

In the last few years, the number of women holding executive positions in India has greatly increased. The question that arises is how much commitment they have to their work in the face of their responsibilities to husband, home and children. A study made of 325 women executives in Ludhiana and Chandigarh revealed a significant relationship between marital status, salary drawn, age, work experience and job commitment. In many of these factors, the attitudes of the women were hardly different from those of men — a considerable change from the situation that previously prevailed both in India and the West.

The Relationship

The purpose of this study was to analyze the relationship between coaches’ professional playing experience and their professional coaching success. The sample (n = 134) included coaches who had the equivalent of three full seasons of head coaching experience in either Major League Baseball (MLB) (n = 46), the National Basketball Association (NBA) (n = 38) or the National Football League (NFL) (n = 50) as determined by the total number of games coached between the years 1997-2007. ANOVAs revealed no significant differences between coaches with more or less professional playing experience and professional coaching success as determined by professional winning percentage. Further, no significant relationship was found between professional playing experience and professional coaching success in MLB (r = -0.16), NBA (r = -0.05) or NFL (r = 0.00). It was concluded that professional playing experience was not a predictor of professional level coaching success. These findings support the notion that sources of knowledge other than playing experience may be necessary and useful in developing coaching expertise.

Israel is situated in the Middle East, which is not a zone of peace but rather of turmoil. In contrast to the West where peace has become the norm, the Middle East exists in a different socio-political time zone. It is war-prone and the use of force still evokes remarkable popular support. The Middle East, similar to other Third World regions, displays a greater propensity for intra- and inter-state conflict as compared to the environments of the developed states. Therefore, the Middle East is not about to be transformed into what Karl Deutsch called a ‘security community’, where recourse to arms is not acceptable for the resolution of inter-state conflict.

The Impact

Abstract Introduction Prior research on travel in the National Basketball Association’s (NBA) regular season has shown that teams journeying west relative to their home base face circadian disadvantages for evening games, while those traveling east have advantages. The current study extends previous research by examining these effects within the NBA playoffs. We hypothesized that teams would have a greater circadian advantage during eastward compared to westward travel. Methods In 2013, the NBA implemented a 7-game series playoff structure, in which teams play an alternating home/away 2-2-1-1-1 format. Data for all 499 postseason games played during the 2013–14 to 2018–2019 seasons were collected from Basketball-Reference and FiveThirtyEight. We investigated the impact of direction of travel based on home base city (same time zone, westward, eastward) and time zones traveled on game outcomes, Elo rating differences (i.e., a team quality metric based on wins and losses), win probability, and team scoring. Results Teams had lower win probabilities following 3-hour westward than same time zone and all eastward travel, while 3-hour eastward travel related to higher probabilities of winning compared to same time and all westward travel (p &lt; .001, d &gt; .95). Teams travelling westward with 2-hour time changes lost significantly more games than those experiencing 1-hour westward (p = .04, OR = 2.45), 1-hour eastward (p = .05, OR = 2.34), and 3-hour eastward changes (p = .02, OR = 4.68). Scoring was significantly higher following eastward travel compared to both westward (p = .001, d = 0.60) and same time zone travel (p = .003, d = 0.44). There were no differences in team quality based on direction of travel or number of time zones traveled, and game outcomes based on overall direction of travel (p &gt; .05). Conclusion Direction and magnitude of travel were related to win probability, team scoring, and game outcomes, whereby teams travelling eastward and within the same time zone gained an advantage over those travelling westward. Adjustment to travel and time changes appear to influence in-game performances and outcomes in the NBA playoffs. Support None

The Impact

Using a sample of students ( N = 118) engaged in an 8-week project to build an e-book chapter, this study finds that cognitive absorption impacts interpersonal conflict and team performance. In particular, virtual teams with aggregated higher levels of focus immersion and temporal dissociation (dimensions of cognitive absorption) demonstrate higher levels of performance and interpersonal conflict. Furthermore, there is an interaction effect between focus immersion and temporal dissociation that moderates the impact on performance and interpersonal conflict. The teams with aggregated high levels of focus immersion and aggregated low levels of temporal dissociation demonstrated the best performance and lowest levels of interpersonal conflict. The authors also found that individuals with high levels of focus immersion preferred asynchronous communication media, whereas individuals with low levels of temporal dissociation preferred synchronous communication media. The implications are discussed.
