A mathematical model of the oar blade - water interaction in rowing

Our aim was to present a mathematical model of rowing and sculling that allowed for a comparison of oar blade designs. The relative movement between the oar blades and water during the drive phase of the stroke was modelled, and the lift and drag forces generated by this complex interaction were determined. The model was driven by the oar shaft angular velocity about the oarlock in the horizontal plane, and was shown to be valid against measured on-water mean steady-state shell velocity for both a heavyweight men's eight and a lightweight men's single scull. Measured lift and drag force coefficients previously presented by the authors were used as inputs to the model, whichs allowed for the influence of oar blade design on rowing performance to be determined. The commonly used Big Blade, which is curved, and it's flat equivalent were compared, and blade curvature was shown to generate a 1.14% improvement in mean boat velocity, or a 17.1-m lead over 1500 m. With races being won and lost by much smaller margins than this, blade curvature would appear to play a significant role in propulsion.     

Tales of the unexpected: coping among female collegiate volleyball players

The purpose of this study was to examine patterns of appraisal, coping, and coping effectiveness in sport. Ten players from a collegiate female volleyball team were interviewed on two occasions, first in the week before a provincial final playoff tournament and in the week following the tournament. Data were transcribed verbatim and subjected to content and idiographic analyses. Athletes generally did not predict or anticipate the stressors they actually experienced during the tournament. Subjective appraisals of effective coping were associated with consistency between proactive and actual coping attempts. Reported effective coping was associated with the attainment of personal performance goals and use of cognitive, behavioral, and emotional coping strategies in the absence of behavioral avoidance. Reported ineffective and partially effective coping was associated with not attaining personal performance goals, and the use of cognitive coping strategies with behavioral avoidance. Finally, older, more experienced athletes reported they coped better than younger, less experienced athletes during the tournament.     

Athletes' evaluations of their head coach's coaching competency

This study provided initial validity evidence for multidimensional measures of coaching competency derived from the Coaching Competency Scale (CCS). Data were collected from intercollegiate men's (n = 8) and women's (n = 13) soccer and women's ice hockey teams (n = 11). The total number of athletes was 585. Within teams, a multidimensional internal model was retained in which motivation, game strategy, technique, and character building comprised the dimensions of coaching competency. Some redundancy among the dimensions was observed. Internal reliabilities ranged from very good to excellent. Practical recommendations for the CCS are given in the Discussion section.     

When empathy hurts: Modelling university students’ word of mouth behaviour in public vs. private universities in Syria

This study examines and compares word of mouth (WOM) behaviour among university students in Syria. To date, little is known about this important phenomenon which is surprising given the deregulated education market in Syria that allows for private universities to compete for students alongside public universities. Using a mixed methods research design and structural equation modelling, our results show faculty individualised attention and student satisfaction were found to be positively related to university image. Further, student satisfaction and university image were found to be direct sources of students’ positive WOM behaviour. We found a moderating effect of university ownership type on university image. Interestingly, we identified six themes showing how support staff empathy could be seen as a source of low student satisfaction. These were defined as deception/credibility/soft‐soapers/suspiciousness: when support staff coax something out of students; confusion/role conflict: resulting from the diverse roles played by support staff while interacting with students; unfairness: when a student notices discrimination in the level of empathy between their peers; privacy: when support staff empathy can be perceived as a kind of intrusion; self‐congratulatory: when a support staff member shows off or praises their empathy; and support staff/student ratio: when this ratio is seen to be small, the empathy effect reverses.
