The service sector increasingly has become the cornerstone of a great number of economies in both the developed and developing world. The main barrier to trade in services is the imposition of domestic regulations which are aimed at ensuring the affordability, availability and efficiency of services. Such domestic regulations are important for services and the General Agreement on Trade in Services (GATS) consequently recognises the right of countries to regulate in order to achieve these goals. The GATS, however, also seeks to discipline such regulations to ensure that they do not hinder trade in services. This article seeks to assess these seemingly competing interests in the context of South Africa's history and its burgeoning telecommunications sector. 相似文献

This study investigated the ability of individuals with experience in gait analysis to identify people by observing features of gait recorded by closed circuit television cameras (CCTV). Seven experienced analysts each viewed five samples of footage. Each sample showed a “target walker” and five “suspect walkers.” The task of the experienced analysts was to determine which, if any, of the “suspect walkers” was the “target walker.” All of the participant “walkers” wore identical loose fitting clothing to mask anatomical and body contour features, and balaclavas to obscure facial features. The overall results showed that the experienced analysts made a correct decision in 124 of 175 cases (71%), significantly better than would have been expected to have occurred by chance (p < 0.05). A significant variation in correct decisions (p < 0.05) was shown to occur between the various angles from which the footage was recorded, footage recorded in the saggital plane showing the highest number of correct decisions. Significantly more correct decisions (p < 0.05) were also shown to occur when the footage of the “target walker” and that of the “suspect walker” were taken from the same angle. The results suggest that individuals with experience in gait analysis perform well in the comparative identification of suspects from CCTV footage, and therefore do have a role to play as expert witnesses in this field. 相似文献

Purpose
Theories of procedural justice have facilitated the development of a process-based approach to policing which emphasizes the fairness of the manner in which the police exercise their discretion. The study examines whether procedurally fair behavior by the police affects two types of citizen behavior during encounters: citizen disrespect toward the police and citizen noncompliance with police requests.Methods
This study uses data from systematic social observations of police-citizen encounters to examine procedural justice factors on citizen behavior. Because of the reciprocal nature of police-citizen interactions, an instrumental variable is used in the statistical analysis to help address the causal relationship between police force and citizen disrespect.Results
The statistical analyses find limited support for procedural justice factors. Two types of procedurally fair behavior by the police, police demeanor and their consideration of citizen voice, are significant in reducing citizen disrespect and noncompliance, respectively.Conclusion
Procedural justice factors have limited and inconsistent impacts on the two types of citizen behavior, and future research should address the limitations of this study and evaluate process-based policing with more data from social observations of police-citizen encounters. 相似文献164.
We report a very unusual case of murder of a 4-year-old male white child who died of asphyxiation. Asphyxia occurred due to 3 factors: manual strangulation, hyperextension of the neck, and atlantoaxial subluxation. The offenses were carried out by a single assailant (the stepfather of the child) who strangled the child with his right hand, using his left hand to pull the hair of the child, forcing the head back and causing hyperextension of the neck, thereby dislocating the first and second cervical vertebrae. 相似文献
