Research participants' views about investigator financial interests were explored. Reactions ranged from concern to acceptance, indifference, and even encouragement. Although most wanted such information, some said it did not matter, was private, or was burdensome, and other factors were more important to research decisions. Very few said it would affect their research decisions, and many assumed that institutions managed potential conflicts of interest. Although disclosure of investigator financial interest information to research participants is often recommended, its usefulness is limited, especially when participation is desired because of illness.  相似文献

Understanding the relationships between youthful gambling, substance use, and other problem behaviors is of interest to researchers studying deviance and to policymakers developing improved prevention strategies. This study used first-order and second-order factor models to test the hypothesis that gambling, alcohol misuse, other drug use, and delinquency were manifestations of a single general deviance construct. Respondents were seventeen to twenty-one year-old youth who were interviewed in two separate general population studies. Contrary to the hypothesis, the second-order model with a single deviance construct did not fit as well as a model specifying only correlations among all first-order factors. A single latent variable representing general deviant behavior did not explain deviance as well as distinct types of problem behaviors. This was true for overall samples and for gender-specific subgroups. Thus, while problem behaviors were related, there also must be uncorrelated antecedents predicting distinct types of youthful problem behaviors.  相似文献

Der überkommene strafrechtliche Schutz „?ffentlicher Denkm?ler“ nach § 304 Abs. 1 Alt. 4 StGB findet trotz ungenehmigter Denkmalzerst?rungen in der Praxis zu wenig Anwendung. Er bleibt wegen des einschr?nkenden Merkmals „?ffentlich“ hinter anderen Alternativen des § 304 StGB wie dem Schutz der Naturdenkm?ler nach § 304 Abs. 1 Alt. 5 StGB oder dem Straftatbestand des V?lkerstrafrechts (§ 11 VStGB) zurück. Da der sozialsch?dliche Charakter bei der Zerst?rung von Denkm?lern stets anzunehmen ist, sollte künftig aus kulturstaatlicher Verantwortung für den Schutz aller Denkm?ler auf das Merkmal „?ffentlich“ in § 304 Abs. 1 Alt. 4 StGB verzichtet werden.  相似文献

Efforts to integrate complementary and alternative medical (CAM) therapies into conventional medical settings are creating a variety of negotiation challenges between various stakeholders. Focusing on the two-party encounter between physician and patient offers a way to understand the application of principled negotiation to perhaps the most fundamental and emotionally charged place within the health care system in which the introduction of CAM therapies is likely to disrupt relationships and produce conflict. This article suggest ways in which the theory and analysis of principled negotiation can add to current liability and ethical frameworks, and might thereby contribute to optimal future health care by helping to wisely integrate CAM therapies into conventional medical care.  相似文献

Assessing law enforcement preparedness to address Internet fraud   总被引:1,自引:0,他引:1  
Recent societal concern regarding computer crime was well documented in the research literature. To date, however, modest research addressed how large, local police and sheriff's departments confront Internet fraud. Using data collected from surveys distributed to the seven hundred largest police- and sheriff's departments, the present article addresses law enforcement: (1) preparedness to enforce Internet fraud crimes; (2) perceptions of Internet fraud; (3) cooperative policing efforts; and (4) Internet fraud information dissemination practices. Among other things, results suggested that individuals within these departments believed Internet fraud was problematic, although they lacked the resources to properly address the problem. These results are discussed as they relate to the organizational design of law enforcement agencies and their potential to adapt to innovative crimes. Suggestions are offered for a more effective approach to confronting Internet fraud.  相似文献
