This paper uses the episode of the Kapp putsch in March 1920 to isolate and analyze a number of high policy themes that dominated the period from the signature of the Treaty of Versailles through to the Franco-Belgian invasion of the Ruhr. These included: the questions of what mechanisms existed to enforce the treaty; the sanctions available to the victorious governments to enforce their will; the position and problems of the German government; the relationship and suspicions existing between Britain and France and the differing aims, ambitions, and approaches of the major participants.  相似文献

On January 1, 1996, a new law took effect in Texas granting certain state citizens the privilege to carry a concealed handgun on their person for the first time since 1871. As a result of this dramatic shift in state law, Texas is now among the growing number of states across the nation who have adopted similar statutory provisions in one form or another. While at least one empiricals study of citizen’s attitudes toward concealed handgun ownership was conducted prior to the law’s effective date, no similar efforts were undertakens to assess the beliefs, perceptions and attitudes of the state’s law enforcement officers about this important social policy. The present study was therefore undertaken in response to the lack of serious attention which the issue of concealed handgun ownership among private citizens has received as it directly relates to the law enforcement profession. Subjects for this study (N=327) were drawn from four Texas law enforcement agencies representing various organizational sizes and missions. While the responses of officers who participated in the study indicate optimism about the law’s potential to deter various types of crime, they also reflect a certain degree of concerns about concealed handgun ownership among private citizens especially as this policy directly relates to perceive inadequacies in statemandated requirements and issues affecting officer safety.  相似文献

From the adoption of the Constitution in 1787, the executive department has been the primary vehicle through which the government of the United States has administered its programs. Their organization and effectiveness are therefore matters that demand constant attention.  相似文献

The psychological assessment battery is an integral part of the selection process used to select patrol officer applicants. Unlike all other procedures used in the selection process, the psychological assessment has not been adequately validated. The purpose of this study was an attempt to provide validation data for a psychological assessment battery. The battery consisted of the Nelson-Denny, Shipley-Hartford, MMPI, and the Motivational Analysis Test (MAT). Performance measures included various measures of training academy performance and field training performance. A stepwise regression and MANOVA/Discriminant Analysis indicated that the psychological tests did predict performance, although an exact predictive equation could not be developed due to the high intercorrelations between predictor variables. This research was sponsored in part by a grant from the School of Applied Arts and Technology, Southwest Texas State University.  相似文献
