Die Drei-Punkte-Regel in der deutschen 1. Fußballbundesliga und der Anteil unentschiedener Spiele

Dilger and Geyer (2007) analysed the impact of introducing the three-point rule in 1995/1996 on the results in the German premier soccer league (1. Fußballbundesliga). The authors argue that this change, among others, would lead to a reduction in the number of draws as the possibility to gain 3 points instead of 2 would cause a higher incentive for winning. Examining the entire n=6194 games in the German premier soccer league 10 years before and after the rule change, respectively, they found a significant difference for this specific period (p<0.01). This finding is interpreted as evidence for the impact of the three-point rule. We contradict this questionable interpretation by Dilger and Geyer (2007). In our reply we show that the implementation of the three-point rule has no (practically relevant) impact on the proportion of draws. For this purpose, all of the n=13,406 matches since 1963/1964 were included in the analysis. The results indicate fluctuations in the percentage of draws during 44 years of existence of the German premier soccer league independently of the implementation of the three-point rule. In light of this, an impact of the three-point rule on the proportion of draws cannot be identified at all.     

A Longitudinal Examination of Validity and Temporal Stability of Organizational Dissent Measurement in France

ABSTRACT

This study examines the extent to which the Organizational Dissent Scale (ODS) maintains validity and temporal stability over time in a French sample. A longitudinal panel study was conducted. The results do not support that the ODS maintains validity nor temporal stability over time. These results are not indicative of problems with the original measure; it could be that conceptually dissent is a different process with different understandings in French culture. Cultural differences may render measures unusable between cultural groups.     

Children's Vulnerability to Interparental Conflict: The Protective Role of Sibling Relationship Quality

This study tested whether the strength of the mediational pathway involving interparental conflict, adolescent emotional insecurity, and their psychological problems depended on the quality of their sibling relationships. Using a multimethod approach, 236 adolescents (M_age = 12.6 years) and their parents participated in three annual measurement occasions. Tests of moderated mediation revealed that indirect paths among interparental conflict, insecurity, and psychological problems were significant for teens with low, but not high, quality bonds with siblings. High-quality (i.e., strong) sibling relationships conferred protection by neutralizing interparental conflict as a precursor of increases in adolescent insecurity. Results did not vary as a function of the valence of sibling relationship properties, adolescent sex, or gender and age compositions of the dyad.     

A Position Statement on Social Justice,Physical Education,and Bullying: A Figurational Sociological Perspective

ABSTRACT

Bullying is increasingly considered to be an important moral, political, and social issue within modern society. Academic research on this issue has mostly been examined through a psychological lens, often using questionnaire data to examine and explain the prevalence of different types of bullying. In this position statement, we apply a figurational sociological perspective to examine issues of school-based bullying in physical education. We critically reflect on attempts to position bullying amongst young people as a “social justice” issue and argue that core figurational principles might potentially help researchers strive toward a more reality-congruent means of conceptualizing the power-relationships that are inherent within bullying. We further maintain that the development of a more detached understanding of issues relating to bullying might provide a more adequate basis to contribute to future ongoing policy development.     

Quantification of maximal power output in well-trained cyclists

ABSTRACT

This study aimed to compare mechanical variables derived from torque-cadence and power-cadence profiles established from different cycle ergometer modes (isoinertial and isokinetic) and modelling procedures (second- and third-order polynomials), whilst employing a novel method to validate the theoretical maximal power output (P_max). Nineteen well-trained cyclists (n = 12 males) completed two experimental sessions comprising six, 6-s maximal isoinertial or isokinetic cycling sprints. Maximal pedal strokes were extracted to construct power–cadence relationships using second- and third-order polynomials. A 6-s sprint at the optimal cadence (F_opt) or optimal resistance (T_opt) was performed to assess construct validity of P_max. No differences were found in the mechanical parameters when derived from isokinetic (P_max = 1311 ± 415, F_opt = 118 ± 12) or isoinertial modes (P_max = 1320 ± 421, F_opt = 116 ± 19). However, R² improved (P < 0.02) when derived from isoinertial sprints. Third-order polynomial modelling improved goodness of fit values (Standard Error, adjusted R²), but derived similar mechanical parameters. Finally, peak power output during the optimised sprint did not significantly differ from the theoretical P_max in both cycling modes, thus providing construct validity. The most accurate P-C profile can be derived from isoinertial cycling sprints, modelled using third-order polynomial equations.
