For the last two decades American police experts developed new police philosophies in order to tackle more successful the increasing crime problems. Community Policing tries to improve the cooperation between the population and the police and to increase the trust in the police. A crucial factor is a meaningful cooperation between the police and the citizens. Problem Oriented Policing aims at structural changes in the organisation and the procedures of the police in public. The police have to investigate the hidden problems and conflicts of an individual offence and to create proactive and long term concepts for the social area of conflicts beyond the specific case. It is doubtful whether these philosophies can be implemented in Germany since the legality principle prohibits meaningful, trustworthy relationships between citizens and police officers. However, if one examines the results of surveys on citizens views and expectations towards the police one finds that the majority of the German citizens favour the postulates of community and problem oriented policing. They expect through these measures an improvement of their life situation in the community and the feelings of safety. If one takes these results seriously one has to question if the legality principle is still appropriate. It seems to hamper new, more promising policing styles which seem to improve life of it's citizens and reflect what the citizens want and expect from their police force.

BACKGROUND Randomized control trials (RCTs) stopped early for benefit (truncated RCTs) are increasingly common and, on average, overestimate the relative magnitude of benefit by approximately 30%. Investigators stop trials early when they consider it is no longer ethical to enroll patients in a control group. The goal of this systematic review is to determine how investigators of ongoing or planned RCTs respond to the publication of a truncated RCT addressing a similar question. METHODS/DESIGN We will conduct systematic reviews to update the searches of 210 truncated RCTs to identify similar trials ongoing at the time of publication, or started subsequently, to the truncated trials ('subsequent RCTs'). Reviewers will determine in duplicate the similarity between the truncated and subsequent trials. We will analyze the epidemiology, distribution, and predictors of subsequent RCTs. We will also contact authors of subsequent trials to determine reasons for beginning, continuing, or prematurely discontinuing their own trials, and the extent to which they rely on the estimates from truncated trials. DISCUSSION To the extent that investigators begin or continue subsequent trials they implicitly disagree with the decision to stop the truncated RCT because of an ethical mandate to administer the experimental treatment. The results of this study will help guide future decisions about when to stop RCTs early for benefit.

Objectives : To evaluate self-esteem, coping styles, and health-related quality of life and their relationships in Polish adolescents and young adults with unilateral complete cleft lip and palate and related sex differences. Design and Participants : Self-report questionnaires measuring self-esteem (Multidimensional Self-Esteem Inventory), coping styles (Coping Inventory for Stressful Situations), and health-related quality of life (WHOQOL-BREF) were completed by 48 participants with cleft lip and palate (age, 16 to 23 years; 31 males, 17 females) and 48 controls without cleft lip and palate (age, 16 to 23 years; 28 males, 20 females) matched for age, place of residence, and socioeconomic status. Results : Regarding self-esteem, individuals with cleft lip and palate scored higher on body functioning (P < .01) and defensive self-enhancement (P < .05). Self-control showed an interaction effect: Females with cleft lip and palate scored higher than controls, but males did not differ between groups (P < .05). Males with cleft lip and palate scored lower than controls in personal power but higher in body functioning (P < .05); females showed no differences between groups. The groups did not differ with regard to coping styles or quality of life, but several correlations were found between self-esteem and coping styles, and quality of life (P < .01). Conclusions : Late adolescents and young adults with and without cleft lip and palate differed little in terms of psychological adjustment measures. The higher scores in defensive self-enhancement of individuals with cleft lip and palate suggest the need for instruments measuring social approval in psychosocial adjustment research involving this group.
