The 608-bp hypervariable region 1 (HV1) sequences from 36 local dogs were analyzed to characterize the population genetic structure of canid mitochondrial DNA (mtDNA). Sixteen haplotypes were identified. A 417-bp segment of this sequence was compared with GenBank sequences from a geographically representative sample of 201 dogs, two coyotes, and two wolves. Sixty-six haplotypes were identified including 62 found only in domestic dogs. Fourteen of these correspond to the 16 local haplotypes and were among the most frequent haplotypes. The local sample was judged to be representative of the much broader geographic sample. No correlation was observed between local haplotypes and the owner's characterization of dog breed. A 60-bp variation "hotspot" within the canid HV1 was identified as a potentially valuable molecular tool, particularly for assaying limited or degraded DNA samples.  相似文献

Research has demonstrated the utility of the MMPI-2 in identifying good and poor performance, dissatisfaction, termination, low performance ratings, unsatisfactory and satisfactory criterion groups, problematic behavior, corruption, and aggression. There is much research to suggest that certain patterns of responding to this measure by officer applicants predict job performance behaviors that supervisors and police executives view unfavorably. This study illustrates the fact that variables which are likely to predict police performance are less obvious and more subtle. Discussion centers on repression and underlying hostility. Authors' Note: William U. Weiss, Ph.D., is professor of psychology, The University of Evansville, 1800 Lincoln Avenue, Evansville IN 47722. At the time this study was done, Jessica Johnson was an undergraduate student research assistant. Gerald F. Serafino, Ph.D., and Ann Serafino are in private practice in Roswell, New Mexico.  相似文献

Three commercially available integrated rapid DNA instruments were tested as a part of a rapid DNA maturity assessment in July of 2018. The assessment was conducted with sets of blinded single-source reference samples provided to participants for testing on the individual rapid platforms within their laboratories. The data were returned to the National Institute of Standards and Technology (NIST) for review and analysis. Both FBI-defined automated review (Rapid DNA Analysis) and manual review (Modified Rapid DNA Analysis) of the datasets were conducted to assess the success of genotyping the 20 Combined DNA Index System (CODIS) core STR loci and full profiles generated by the instruments. Genotype results from the multiple platforms, participating laboratories, and STR typing chemistries were combined into a single analysis. The Rapid DNA Analysis resulted in a success rate of 80% for full profiles (85% for the 20 CODIS core loci) with automated analysis. Modified Rapid DNA Analysis resulted in a success rate of 90% for both the CODIS 20 core loci and full profiles (all attempted loci per chemistry). An analysis of the peak height ratios demonstrated that 95% of all heterozygous alleles were above 59% heterozygote balance. For base-pair sizing precision, the precision was below the standard 0.5 bp deviation for both the ANDE 6C System and the RapidHIT 200.  相似文献

傅汎际与李之藻撰写的《寰有诠》(1628)主要翻译自亚里士多德《论天》的拉丁文评注,然而其第一卷加上了从哲学和圣经方面介绍的基督教创造论.在哲学论述方面,通过考证发现,《寰有诠》吸收了阿奎那在《争议问题集:论天主的德能》中的论点,把创造论放在形而上学的框架中去理解,揭示出作为第一本原的天主与万物之间最基本的关系.如此,《寰有诠》为会通创造论与宋明理学提供了非常恰当的基础.  相似文献

In this article, the authors discuss the role of emotions in mediation with the goal of providing practical insights that can improve the mediation process. Their assumption is that emotion is ever-present, particularly in conflict, and that acknowledging and addressing underlying emotions facilitates conflict transformation during the mediation process.  相似文献

Despite the known deficits in sleep that occur during adolescence and the high prevalence of substance use behaviors among this group, relatively little research has explored how sleep and substance use may be causally related. The purpose of this study was to explore the longitudinal bi-directional relationships between sleep duration, sleep patterns and youth substance use behaviors. Participants included 704 mostly white (86.4?%) youth, 51?% female, with a baseline mean age of 14.7?years. Self-reported substance use behaviors included past month alcohol, cigarette, and marijuana use. Sleep measures included sleep duration on weekends and weekdays, total sleep, weekend oversleep, and weekend sleep delay. Cross-lagged structural equation models, accounting for clustering at the school level, were run to determine the longitudinal association between sleep and substance use adjusting for socio-demographic characteristics, pubertal status, body mass index z-score, and depressive symptoms. Cigarette use and weekend sleep were bi-directionally related as were marijuana use and total sleep. No other bi-directional associations were identified. However, alcohol use predicted shorter weekend oversleep and marijuana use predicted increased weekend sleep and weekend oversleep. Sleep patterns and duration also predicted adolescents' cigarette, alcohol, and marijuana use. Sleep, both patterns and duration, and substance use among youth are intertwined. Future research is needed to explore these bi-directional relationships, as well as other important contextual factors that may moderate these associations.  相似文献
