Although children are being more frequently called as witnesses in court proceedings, they often do not tell the truth. If lying is defined as giving a false statement for personal gain, then lying is only one of several causes for children not giving an accurate account of events. Other reasons include an immature brain, a congenitally acquired defect in the central nervous system, or the presence of an emotional disturbance such as psychosis or hysteria. The desire of a child to please others--that is, parents, therapists, or lawyers--may also result in an invalid statement. These factors and motivations should be considered in trying to interpret a youngster's statement. 相似文献

Recent Supreme Court decisions have signaled the need for sound empirical studies of the secondary effects of adult businesses on the surrounding areas for use in conjunction with local zoning restrictions. This study seeks to determine whether a relationship exists between adult erotic dance clubs and negative secondary effects in the form of increased numbers of crimes reported in the areas surrounding the adult businesses, in Charlotte, North Carolina. For each of 20 businesses, a control site (matched on the basis of demographic characteristics related to crime risk) is compared for crime events over the period of three years (1998–2000) using data on crime incidents reported to the police. We find that the presence of an adult nightclub does not increase the number of crime incidents reported in localized areas surrounding the club (defined by circular areas of 500- and 1,000-foot radii) as compared to the number of crime incidents reported in comparable localized areas that do not contain such an adult business. Indeed, the analyses imply the opposite, namely, that the nearby areas surrounding the adult business sites have smaller numbers of reported crime incidents than do corresponding areas surrounding the three control sites studied. These findings are interpreted in terms of the business mandates of profitability and continuity of existence of the businesses. 相似文献

In a study of the relationship between health habits and depression, 80 high school students, selected on an availability basis, were administered a Health Behaviors Questionnaire (HBQ) and the Beck Depression Inventory (BDI). The HBQ and the BDI significantly correlated (r=0.43p<0.01). Those who smoked were more frequently depressed than those who did not (X
2=10.5p<0.05), and those who used drugs other than marijuana were depressed more frequently than those who did not (X
2=9.2p<0.01). Mildly overweight boys (overweight by more than 5% of their ideal weight) and mildly under-weight boys (underweight by more than 5% of their ideal weight) were moreThis research was supported in part by a grant from the American Diabetes Association and by National institute of Health Grant MH 15529.Received his M.D. at George Washington School of Medicine.

The more pounds underweight the girls were, the more depressed they were (r=0.482, p<0.05). The closer the weight of a girl who perceived herself as overweight was to her ideal weight, the more depressed she was (r=–0.428,p<0.05). 相似文献

This paper examines the provision of campaign contributions made by economic interests to incumbents seeking reelection in the 1984, 1986, and 1988 California Assembly elections. The study tests whether the distribution of campaign contributions by specific industrial sectors corresponds to legislator possession of the policy property rights associated with membership on relevant Assembly standing committees. A non-parametric statistical model compares the distribution of campaign contributions from groups within a given industrial sector to members of relevant policy committees with the distribution of contributions from all other contributor classes. The empirical analysis confirms that committee assignments significantly affect the allocation of special interest resources in Assembly elections, substantiating the importance of institutional considerations in influencing special interest activity. 相似文献
