This research examines the effect of the initial socialization process on the level of professionalism among a cohort of thirty-six police recruits. These police recruits were surveyed at two points in their careers about their degree of professional commitment to the occupation. The first test period immediately followed their appointment to the force, and the second test period was six months later. Our principal finding was a significant decline in the level of professional commitment among the recruits between the two test periods; related findings to the professionalization process were similarly noted. The research demonstrates the effect of the initial socialization process among police and suggests ways police administrators can minimize the effect of initial socialization on level of professionalism, depending on their theoretical orientation. 相似文献

The literature on age estimation from the structure of adult human teeth is reviewed. Several anatomic changes of teeth have been shown to be valuable in age determination, but there is still controversy concerning the accuracy of cemental annulation. It is believed that improvements in age estimation can be made using direct measurement rather than scoring systems. 相似文献

Conclusion While I agree with Birch that the four cases he cites are cases that justify secession, I disagree that these are the only cases. In fact, I disagree with his approach that there can ever be a case where secession is not justified. If a group of individuals would rather be a part of a different political entity than the one to which they are currently a part, they have an inalienable right to form a political entity that is more to their liking, or to join with an already existing political entity. It is not a matter of permission. It is a matter of right. And there is no theoretical reason why the size of the seceding group cannot be as small as a single individual, although there may be some technical difficulties involved when the entity seceding is this small.He has authored or co-authored more than 30 books and has written more than 200 articles for a variety of professional journals. 相似文献
