Incarcerated fathers (N?=?185) in a maximum security prison were interviewed about their relationship with their children and their perceptions of social support. The OLS regression on social support included the inmates?? perception of the father-child relationship and other factors (demographic, sentence, child-related, and program participation). Results indicate the fathers?? perception of the relationship with their children made a positive contribution to their appraisal of social support from all sources. ??Other?? program participation and being African American were related to the fathers?? perception of social support from others. Recommendations include using social support strategies in pre-release and post-release programs.  相似文献

Although there is a knowledge base regarding theoretical and empirical research on attitudes toward the police, this line of research has not fully examined the sources of such attitudes, and in particular the extent to which attitudes toward the police are influenced by ethnic identity. The present study examined the role of ethnic identity in African American adolescent offenders' perceptions of general police discrimination, direct police contact, procedural justice, and police legitimacy. Analyses showed that youth with a stronger sense of ethnic identity perceived more police discrimination but reported more positive beliefs about police legitimacy. The findings underscore the importance of considering processes that may make legal socialization experiences more salient for adolescents, and demonstrate the complex role that ethnic identity plays in relation to discrimination.  相似文献

Abstract: The proper identification of illicit plants such as Papaver somniferum L (opium poppy) is important for law enforcement agencies. The identification of opium poppy was presently tested using 10 genetic markers that are universal for all plants or specific to a few poppy plants. The genetic distances of universal markers such as nuclear internal transcribed spacer (ITS), 18S rRNA, plastid rbcL, and trnL‐trnF intergenic spacer (IGS) of 14 species included in the Papaveraceae and Fumariaceae family were acquired by sequence comparisons. Both the ITS region and trnL‐trnF IGS showed high levels of interspecific divergence. Six Papaver genera‐specific markers were developed from coding regions involved in morphine biosynthesis. Three markers (TYDC, NCS, and BBE) produced amplicons only in opium poppy, providing a presence/absence test for opium poppy, while three additional markers (CYP80B1, SAT, and COR) were genus specific. These 10 markers might be useful for the forensic DNA analysis of opium poppy.  相似文献

Abstract:  We retrospectively reviewed autopsy records at a statewide medical examiner's office in order to identify and characterize deaths due to child abuse. In a 6-year period in New Mexico, the medical examiner investigated 45 deaths determined to be child abuse-related. Decedents were predominantly male (68.9%), Hispanic White (53.3%), and all were 5 years of age or younger, with a median age of 1 year. Head injuries were the most common cause of death (44.4%), followed by battered baby syndrome (15.6%). Relatives were involved as alleged perpetrators in 80% of the cases, with the father most often implicated (36.1% of cases), and 88.9% of child abuse injuries resulting in death occurred in the family's residence. Toxicology was positive in 26.7% of cases, but only two cases had substances of abuse present. Information on risk factors such as prematurity, parental age, and history of abuse was also collected.  相似文献

The purpose of the present study was to identify salivary molecules carrying the ABH blood group antigens in Koreans and to investigate the changes in these antigens according to processing and storage of saliva samples. Secretor or non-secretor phenotypes and salivary components carrying the ABH antigens were identified in 90 subjects, 30 subjects in each ABO blood group, by SDS-PAGE and immunoblotting. Saliva samples were then obtained from 12 secretors-two males and two females in each ABO blood group and aliquots of both fresh saliva samples and their supernatants after centrifugation were stored at room temperature, 4, -20 and -70 degrees C. The same experiments were performed after 1, 3 and 6 months to investigate changes in the blood group antigens. In all 68 secretors, high-molecular-weight salivary mucin (MG1) was found to be the primary carrier of the ABH antigens. A salivary component of approximately 80 kDa also carried H antigen in seven saliva samples of 22 blood type O secretors. The blood group antigens were better detected in centrifuged samples. In saliva samples preserved at room temperature and 4 degrees C, the blood group antigens were either not detected or detected as degraded molecules. No change was found in the blood group antigens in saliva samples preserved at -20 and -70 degrees C for 6 months.  相似文献

A method for simultaneous enantiomeric separation of ephedrine, pseudoephedrine, and methamphetamine (MA) in a single run by simple capillary zone electrophoresis (CZE) with beta-cyclodextrin as a chiral selector is described. The effects of the buffer pH, phosphate concentration, beta-cyclodextrin concentration, voltage and temperature on the peak resolution were examined. Good enantiomeric resolution was attained for each analyte under our optimized conditions: 15 mM beta-cyclodextrin, 300 mM NaH2PO4 at pH 2.5 with an uncoated capillary (64.5 cm x 50 microm), applied potential at 20 kV and temperature at 30 degrees C. Ultraviolet (UV) detection at a fixed wavelength (200 nm) was employed using a diode array detector. Using phentermine as an internal standard, migration times for all analytes are reproducible within 0.16% for intra-day and 0.6% for inter-day runs. Application of this method to the analysis of confiscated drugs is discussed.  相似文献

Zusammenfassung Seit einem Jahr liegen die thematische Strategie für den Bodenschutz und der Entwurf der Bodenrahmenrichtlinie vor, mit denen die Europ?ische Kommission das europ?ische Umweltrecht komplettieren und einen nachhaltigen Umgang mit den Bodenressourcen erreichen will. Jahrzehnte vorher hatten schon die Welt-Boden-Charta und die Europ?ische Bodencharta eine nachhaltige Bodennutzung gefordert, um der anhaltenden Bodendegradation Einhalt zu gebieten. Vor 15 Jahren hatte die Weltgemeinschaft die Rio-Deklaration über Umwelt und Entwicklung und einen Aktionsplan für diese Deklaration, mit denen nachhaltige Entwicklung, nachhaltige Ressourcennutzung und nachhaltiger Bodenschutz umgesetzt werden sollen, vereinbart. Der Beitrag stellt die Strategie, die Rahmenrichtlinie und den Diskurs zwischen den am Entscheidungsprozess beteiligten Organen und Interessenvertretungen von Landwirtschaft und Industrie, der noch im Gange ist, dar. Auch werden einige Schlüsselthemen der Weiterentwicklung des Bodenschutzes, l?sungsbedürftige theoretische Fragen, die im Hintergrund der Auseinandersetzungen stehen, skizziert.  相似文献

Of the 110 species of genus Papaver, only Papaver somniferum and P. setigerum are controlled poppies in Korea. All poppy samples share similar morphology therefore it is important to check if they contain controlled substances such as morphine and codeine for forensic purpose. Since the alkaloid content of Papaver plants varies according to their growing stage, chemical components analysis alone is not enough to identify exact species. In 2010, hundreds of poppy plants suspected to be P. somniferum were found in Jeju Island, South Korea. They had a slightly different but overall similar appearance to P. somniferum. Using GC-MS analysis, codeine, rhoeadine, papaverine, protopine, noscapine, setigeridine and trace amounts of morphine were detected in these samples. Although their chemical components were different from what has been described in literatures for P. setigerum, they could be assumed to be P. setigerum based on their morphological features and GC-MS results. Also, chromosome numbers using their seeds showed 2n=44 and the numbers were in accordance with those of P. setigerum. Nucleotide substitution or insertion/deletion of ITS (internal transcribed spacer), 18S rRNA (ribosomal RNA), rbcL (large subunit of ribulose 1,5-bisphosphate carboxylase), trnL-trnF IGS (intergenic spacer), trnL intron and psbA-trnH were assessed as universal genetic markers for P. setigerum. Also, genetic analysis using six target genes involved in the biosynthesis of benzylisoquinoline alkaloids, including TYDC (tyrosine/dopa decarboxylase), SAT (salutaridinol-7-O-acetyltransferase), BBE (berberine bridge enzyme), COR (codeinone reductase), CYP80B1 ((S)-N-methylcoclaurine 3'-hydroxylase) and NCS (norcoclaurine synthase) were tested as Papaver-specific genetic markers by the existence of their PCR products. From the results, the sequences of the 6 universal genetic markers and 6 Papaver-specific genetic markers for P. setigerum were identified and then Genbank accession numbers of them were registered in NCBI. Also, the trnL intron and psbA-trnH nucleic acid sequences of the 7 Papaver species were identified and registered.  相似文献

The aims of this study were to investigate the sex discriminating potential of the talus in Koreans and compare this with other analyses in different populations. Statistical analyses were performed using data from nine measurements acquired from 140 tali (70 men, 70 women). The talus of Koreans is dimorphic between sexes in all measurements (p < 0.01). Discriminant function equations were generated by univariate, multivariate, and stepwise methods with a range of accuracy from 67.1 to 87.1%. Stepwise equations of other populations did not discriminate the sex of the Korean sample as accurately as each equation's own accuracies. The variables with high accuracy in this study are useful for sex determination of Koreans on the basis of confirmation of population specificity.  相似文献

Since the mid-1990s, the index crime rate has steadily decreased while the rate for Part II offenses has increased. The current study examines these differences from 1990 to 2004 using arrest rate data from the 35 largest cities in the state of Texas. Cluster regression analyses is employed to examine the effect of city size and city location, whether the city is part of a larger metropolitan area or “stand-alone,” to explain variation in juvenile and adult arrest rates by category of offense (violent, property, Part II) while controlling for the influence of social disorganization variables. Findings indicate that differences exist in the arrest rates for almost all types of offenses in mid-size versus very large cities. Contrasting adult versus juvenile arrest rates, city size and city location offer limited explanation for variation over time. Implications of these findings are discussed in the context of suggested policy and research directions.  相似文献
