This study investigated potential markers within chromosomal, mitochondrial DNA (mtDNA) and ribosomal RNA (rRNA) with the aim of developing a DNA based method to allow differentiation between animal species. Such discrimination tests may have important applications in the forensic science, agriculture, quarantine and customs fields. DNA samples from five different animal individuals within the same species for 10 species of animal (including human) were analysed. DNA extraction and quantitation followed by PCR amplification and GeneScan visualisation formed the basis of the experimental analysis. Five gene markers from three different types of genes were investigated. These included genomic markers for the beta-actin and TP53 tumor suppressor gene. Mitochondrial DNA markers, designed by Bataille et al. [Forensic Sci. Int. 99 (1999) 165], examined the Cytochrome b gene and Hypervariable Displacement Loop (D-Loop) region. Finally, a ribosomal RNA marker for the 28S rRNA gene optimised by Naito et al. [J. Forensic Sci. 37 (1992) 396] was used as a possible marker for speciation. Results showed a difference of only several base pairs between all species for the beta-actin and 28S markers, with the exception of Sus scrofa (pig) beta-actin fragment length, which produced a significantly smaller fragment. Multiplexing of Cytochrome b and D-Loop markers gave limited species information, although positive discrimination of human DNA was evident. The most specific and discriminatory results were shown using the TP53 gene since this marker produced greatest fragment size differences between animal species studied. Sample differentiation for all species was possible following TP53 amplification, suggesting that this gene could be used as a potential animal species identifier. 相似文献

This longitudinal study of 134 female high school seniors investigated the relationship between attachment cognitions and school and work functioning two years later. School functioning was indexed by interviewer-rated strain, stressful events, academic performance, and self-reported attitudes toward college. Work functioning was indexed by interviewer-rated strain, stressful events, and self-reported attitudes toward work. Attachment cognitions were found to be correlated with school strain, number and stress of school-related events as well as self-reported satisfaction, stress, and problems meeting deadlines. Attachment cognitions were found to be correlated with work strain, work satisfaction, tendency to overcommit, and performance anxiety. Most of these relationships persisted even when initial symptomatology was accounted for. These findings lend support to the hypothesis, derived from attachment theory, that secure attachment cognitions provide a secure base that allows the late adolescent to negotiate the challenges of college and work successfully.This research was supported by a PHS National Research Service Award to the first author, and by a grant from the W. T. Grant foundation to the second.Postdoctoral fellowDoctoral candidate 相似文献

The California Rand study focused major attention on the potential threat that felons on probation presented to the public. Their findings of a 65% rearrest rate during a 40-month follow-up of 1672 felons raised considerable concern but left one key question unanswered: are those disturbing results unique to California or are they representative of a nationwide crisis generated by the critical prison overcrowding problem? The authors of the present study replicated the Rand report for the State of Missouri in an attempt to answer those questions. A total of 2083 felons from the most urban population of Missouri were tracked for the same 40-month period utilized by Rand, with very different results. The Missouri rearrest rates were found to be a respectable 22%. The obvious conclusion is that felony probation is an effective alternate to prison in Missouri, and the Rand study may not be representative of felony probation in general. 相似文献

How do we explain high rates of investment in the production of oil palm in Indonesia under conditions of legal uncertainty and uneven protection of property rights? This article argues that what are commonly seen as deficiencies in the formal institutional environment actually enabled investment, but only when informal institutions were able to provide investor assurances. Although the finding that informal institutions provide investor assurances is not new, this study addresses outstanding questions about how such informal institutions work. An examination of the micro-level details of informal institutions in the oil palm industry shows that informal institutions frequently grouped under umbrella terms such as ‘patronage’ or ‘relational ties’ are not uniform. Rather, two types of informal relational tie operate to provide investor assurances: clientelistic and co-investment. Although they serve similar purposes, clientelistic ties work well only under restrictive conditions and are vulnerable to decay. Co-investment, in contrast, is a more robust informal institution, especially when political power is fragmented. Although co-investment provides investor assurances under conditions of legal uncertainty, it remains a particularistic solution and does not guarantee generalized public interest protections. 相似文献

The American tradition of experimental investigation of electoral phenomenon indicates that the medium, as well as the message, is important. Highly controlled experiments give insight into the nature of voter decision making. The importance of partisanship is especially pronounced. Field experiments probe the effectiveness of the mediums of telephone, mail, and personal contact as well as the message dimensions of moralistic and rational appeals in actual electoral campaigns. Collectively, these experimental studies allow strong inferences about electoral behavior. 相似文献

Despite the importance of European Union negotiations, the majority of scholarly attention has not been directed towards the means by which policy is coordinated in member states. This article addresses one aspect of this gap by focusing upon the structures which existed for UK policy making during the 1990–91 IGC negotiations. Particular emphasis is attached to the key role of officials, who often proved crucial to the extraction of compromises at the European level, and the manner by which policy was constrained by the inability of the Prime Minister to dominate Cabinet. 相似文献
