The present article focuses upon the much-neglected topic of white working class youth — the children of another other America. Based upon the available literature as well as upon a recent program of ethnographic research, the institutional settings — community, family, school — within which working class youth grow up are examined with particular emphasis on their climate and values. Attention is paid to the heterogeneity contained within this segment of the population pointing to four distinct types: collegians, greasers, hippies, and those encapsulated in family life. The article points to factors that promote a potential increase in residential social class homogeneity that, in turn, promotes class values, social and personal expectations, and modal relationships that increasingly diverge from the norms of an urban-industrial middle class society and that in considerable measure either contribute to a growing conservative alienation from the larger society or make adjustments to that society more problematic for its youth. The emergent picture of white working youth in part resembles that of youth in general, but in a more significant measure is much different from that found in either higher or lower social strata.This research was supported by USPHS-NIH Contract 70-511 and USPHS-NICHD Grant No. 04156.Received Ph.D. in Sociology from the University of Chicago.

This paper describes a procedure for the determination of psilocin and psilocybin in mushroom extracts using high-performance liquid chromatography with postcolumn chemiluminescence detection. A number of extraction methods for psilocin and psilocybin in hallucinogenic mushrooms were investigated, with a simple methanolic extraction being found to be most effective. Psilocin and psilocybin were extracted from a variety of hallucinogenic mushrooms using methanol. The analytes were separated on a C12 column using a (95:5% v/v) methanol:10 mM ammonium formate, pH 3.5 mobile phase with a run time of 5 min. Detection was realized through a dual reagent chemiluminescence detection system of acidic potassium permanganate and tris(2,2'-bipyridyl)ruthenium(II). The chemiluminescence detection system gave improved detectability when compared with UV absorption at 269 nm, with detection limits of 1.2 x 10(-8) and 3.5 x 10(-9) mol/L being obtained for psilocin and psilocybin, respectively. The procedure was applied to the determination of psilocin and psilocybin in three Australian species of hallucinogenic mushroom. 相似文献

The performance of the sub-population model first proposed by Balding and Nichols [D.J. Balding, R.A. Nichols, DNA profile match probability calculation: how to allow for population stratification, relatedness, database selection and single bands. Forensic Sci. Int. 64 (1994) 125-140] is examined using a simulation approach. This work extends the investigations of Curran et al. [J.M. Curran, J.S. Buckleton, and C.M. Triggs, What is the magnitude of the sub-population effect? Forensic Sci. Int. 135 (2003) 1-8]. In particular the effect of underestimating the coancestry coefficient, theta, and the effect of departures from the modelling assumptions were investigated. The model tends to give strongly conservative estimates if the estimate for the coancestry coefficient is accurate. If this coefficient is underestimated then a larger fraction of cases give non-conservative estimates. Departures from the modelling assumption that the sub-population is in Hardy-Weinberg and linkage equilibria appear to have very little effect. 相似文献

The post-1999 devolution project has resulted in a major recalibrationof the preexisting arrangements for making European Union policywithin the United Kingdom. The devolved administrations in Scotlandand Wales (but not the English regions) have gained in electorallegitimacy and legislative powers, and thereby have a greaterclaim to consultation with UK central government. Four key characteristicsof European Union policymaking in a devolved United Kingdomare identified. The legal contingency of the "devolveds" statushas not yet impeded traditional cooperative relations betweengovernment tiers, but the stability of the new arrangementsremains in question. The UK case is compared with European Unionregionalization in other member states and a distinction isdrawn between a cooperative regionalist approach (the devolveds)and a consultative one (the English regions). 相似文献

To obtain a reliable estimation on the yield of illicit indoor cannabis cultivation in The Netherlands, cannabis plants confiscated by the police were used to determine the yield of dried female flower buds. The developmental stage of flower buds of the seized plants was described on a scale from 1 to 10 where the value of 10 indicates a fully developed flower bud ready for harvesting. Using eight additional characteristics describing the grow room and cultivation parameters, regression analysis with subset selection was carried out to develop two models for the yield of indoor cannabis cultivation. The median Dutch illicit grow room consists of 259 cannabis plants, has a plant density of 15 plants/m(2), and 510 W of growth lamps per m(2). For the median Dutch grow room, the predicted yield of female flower buds at the harvestable developmental stage (stage 10) was 33.7 g/plant or 505 g/m(2). 相似文献

Gang violence creates serious safety and security concerns in the community and prisons. Treated gang and nongang members recidivated significantly less in a 24-month follow-up than their untreated matched controls. Treatment consisted of high intensity cognitive-behavioral programs that follow the risk, need, and responsivity principles (Andrews & Bonta, 2003). The treated gang members who recidivated violently after treatment received significantly shorter sentences (i.e. they committed less serious offences) than their untreated matched controls. Untreated gang members had significantly higher rates of major (but not minor) institutional offences than the other three groups. Correctional treatment that follows the risk, need and responsivity principles appears able to reduce recidivism and major institutional misconduct. Effective correctional treatment should be considered as one of the approaches in the management and rehabilitation of incarcerated gang members. 相似文献

What do we really know about applicants to graduate school?How much information is in an applicant's file? What do we learnby having graduate admissions committees read and score applicantfiles? In this article, I develop a statistical model for measuringapplicant quality, combining the information in the committeemembers' ordinal ratings with the information in applicants'GRE scores. The model produces estimates of applicant qualitypurged of the influence of committee members' preferences overostensibly extraneous applicant characteristics, such as genderand intended field of study. An explicitly Bayesian approachis adopted for estimation and inference, making it straightforwardto obtain confidence intervals not only on latent applicantquality but over rank orderings of applicants and the probabilityof belonging in a set of likely admittees. Using data from applicationsto a highly ranked political science graduate program, I showthat there is considerable uncertainty in estimates of applicantquality, making it impossible to make authoritative distinctionsas to quality among large portions of the applicant pool. Themultiple rater model I develop here is extremely flexible andhas applications in fields as diverse as judicial politics,legislative politics, international relations, and public opinion. 相似文献

The Data Protection Act 1998 purports to implement European legislation which aims to protect the privacy of individuals. There were such concerns about the implications of the Act for certain research and audit that it became necessary to enact further legislation to enable such essential activities to continue. Although this empowers the Secretary of State for Health to approve proposals for these purposes, there should still be a requirement that the use of identifiable personal information without consent must be justified on compelling public interest grounds. It is this that can confound those seeking to rely on such justification. There can either be too cavalier an approach to the issue, and/or there is little sense of what considerations should come into play. This paper attempts to highlight some of the difficulties that are theoretically raised by some audit activities and set out the legal framework within which they must operate. However, the key focus is on how ethical considerations might inform the public interest argument. 相似文献
