When I first arrived here a few months ago, I couldn't help but notice several work projects going on all around me. A new dorm was being built on campus where I would be teach-ing, as well as a courtyard being repaved and bricked in front of the female students' dormitory, and a building next to my gym was being renovated. I wondered how long it would take to finish these large tasks, espe-cially the courtyard, as school would begin in about a week, and it would be a mess for students to have to walk through mud, over piles of sand, and around stacks of bricks to get where they wanted to go.  相似文献

In an effort to take positive steps toward coping with problems for families and children created by high levels of separation and divorce, ever increasing civil caseloads and the exposure of children to interparental conflict, court‐affiliated educational programs have emerged in the United States for parents separating from their spouse or partner or going through a divorce. This article will provide an overview of the creation of such programs and their development, which includes a discussion regarding the numerous states currently mandating parents to attend. It will summarize some of the research which has been conducted as to the efficacy of the programs and will provide the results of our nationwide research for each state's parent education status. There is a discussion of domestic violence issues and sensitivities in the context of parent education programs and possible future directions for mandatory parent education.  相似文献

Although flag burnings today rarely draw the amount of attention they received in the late 1980s, efforts to protect the flag have persisted for nearly a decade. Accordingly, the flag protection campaign has captured the interest of intellectuals from various academic backgrounds, including political scientists, egal scholars, and journalists. Conspicuously absent from the literature on flag desecration, however, are sociologists and criminologists. Combining historical evidence with recent cases, this article unveils key sociological aspects of social control, including formal and informal responses to flag desecration.  相似文献

Under plausible circumstances, a monopolist in one market canuse its control of prices in that market to force competingdownstream buyers to sign tying contracts that will lever itsmonopoly into another market. Specifically, the monopolist ofthe tying good can place each downstream buyer in a prisoner'sdilemma by offering them more favorable pricing on the tyinggood if they sign a requirements-tying contract covering thetied good. Since a buyer benefits on receiving more favorablepricing on the tying good and the competitors do not, and suffersif the competitors receive more favorable pricing on the tyinggood and the buyer does not, buyers will sign the tying contracteven when they would earn higher profits if they all refusedto sign. This enables a monopolist in one market to inefficientlyexclude an entrant in another market.  相似文献

We studied the allele frequency distribution of 21 autosomal STR loci contained in the AmpFlSTR® Identifiler™ (Applied Biosystems), the Powerplex®16 (Promega) and the FFFL (Promega) multiplex PCR kits among 936 individuals from the Royal Kingdom of Bhutan. As such these are the first published autosomal DNA results from this country.  相似文献

This model evaluates the use of dental stone casts derived from maxillary tissues and from the internal aspects of maxillary dentures for edentulous postmortem identification. Tissue topography of the total cast and of rugae tracings photographed from the casts were evaluated for identification accuracy in twenty-eight trials for each of the two designs. Eight casts were examined in each trial. The trial was designed as matching or nonmatching, and as an equivocal or unequivocal decision by the examiner. Unequivocal decisions with 100% accuracy resulted when the entire dental cast was evaluated. Seventy-nine percent accuracy with equivocation in some trials resulted when only rugae tracings from the casts were evaluated. This investigation supported use of stone casts derived from the internal anatomy of maxillary dentures for forensic science identification when cast topography in toto was considered.  相似文献

Private nonprofit organizations play a major role in delivering a range of publicly funded social services. Aggregate data from a recent Urban Institute study reveal that recent federal cutbacks have affected the services, programs and clients of NPOs. An examination of specific agencies in Maricopa County (Phoenix) reveals that many service providers have adopted a business approach to their services and clients, treating them as commodities. In general, agencies serving clients with Resource Mobilization Potential-youth and elderly-have fared better than those dealing primarily with poor adults.  相似文献
