Prevention science has produced information about risk and protective factors that predict adolescent drug use and related problem behaviors. This paper investigates the Communities That Care Youth Survey that measures multiple risk and protective factors. Using a sample of 172,628 students who participated in surveys administered in seven states in 1998, analyses were conducted to test the factor structure of these risk and protective factors and to test the equivalence of the factor models across five racial/ethnic groups (African Americans, Asians or Pacific Islanders, Caucasians, Hispanic Americans, and Native Americans), four grade levels (6th, 8th, 10th, and 12th) and both gender groups. Results support the construct validity of the surveys risk and protective factor scales and indicate that the measures are equally reliable across males and females and five racial/ethnic groups. Implications of these findings for science-based prevention planning are discussed. 相似文献

The technique of isoelectric focusing in ultra-thin polyacrylamide gels as a method of typing human red cell phosphoglucomutase (PGM1) has been studied. Typing was possible without the samples attaining true equilibrium focusing conditions. The isozyme patterns so obtained were clearly defined and free from distortion. The importance of assessing relative band intensities when interpreting the isozyme patterns is discussed. Our experience of using the technique to analyse casework material is described. 相似文献

Although politicians, police, and others have often advocated the expansion of police employment in the effort to control crime, the empirical relationship between police employment and crime rates has seldom been systematically explored. This study incorporates variables which are causally related both to crime and police employment roles for the 252 northern and northeastern suburbs for which police employment and crime data are available for 1970–1972. Separate analyses of violent and property crime are undertaken, incorporating data on police employment as a causally related variable along with several other determinants of crime identified in earlier studies. The analysis suggests that police employment and crime rates are reciprocally related, and that these relationships offer more support for a “labeling” than a “deterrence” perspective. 相似文献

The relationship between socioeconomic resources and political participation has been the subject of considerable normative-empirical debate. The present article addresses the problem on the basis of Norwegian survey data (N = 1,170) with the intent of testing both the resource-involvement relationship and the possible consequences of value over-representation among the most active citizens. The analysis of resource-involvement dependency in relation to Robert Dahl's norm-set for ‘non-cumulative resource distributions' shows only two resources to be of potential difficulty for pluralist expectations: education and gender. Other expectations as to resource-involvement inequality prove to be nonfounded for Norway. A further test of the consequences of pedagarchal and patriarchal over-representation shows the former to imply a general ‘progressive’ bias in political values, while the latter has no clear-cut ideological implications. 相似文献
