Cell line DNA typing in forensic genetics--the necessity of reliable standards   总被引:15,自引:0,他引:15  
The incorporation of reference DNA is crucial to the validation of any DNA typing protocol. This paper aims to provide a panel of reference DNAs for actual forensic profiling strategies, i.e. autosomal and gonosomal STR typing as well as mtDNA sequencing. We have characterised three human lymphoid cell lines, GM9947, GM9948 and GM3657, and considered 58 autosomal and gonosomal microsatellites as well as the mitochondrial control region sequence. Well-established markers and STRs recently developed for forensic use were involved. K562 DNA samples which we purchased from two different suppliers were also analysed. They revealed conflicting results with regard to the ChrX STR marker genotype. Hence, we suggest that K562 is no longer used for the calibration of profiling techniques. Our investigation establishes a panel of one female and two male DNA samples as an STR allelic ladder calibration tool and offers information on six alleles of each autosome (AS) marker, three alleles of each X chromosome (ChrX) marker and two alleles of each ChrY marker. In addition, sequences of the mitochondrial control region of the three DNAs are communicated in order to provide sequencing quality control.  相似文献

The Spanish and Portuguese ISFG Working Group (GEP-ISFG) carried out a collaborative exercise in order to asses the performance of two Y chromosome STR tetraplexes, which include the loci DYS461, GATA C4, DYS437 and DYS438 (GEPY I), and DYS460, GATA A10, GATA H4 and DYS439 (GEPY II). The groups that reported correct results in all the systems were also asked to analyse a population sample in order to evaluate the informative content of these STRs in different populations. A total of 1020 males out of 13 population samples from Argentina, Brazil, Costa Rica, Macao, Mozambique, Portugal and Spain were analysed for all the loci included in the present study. Haplotype and allele frequencies of these eight Y-STRs were estimated in all samples. The lowest haplotype diversity was found in the Lara (Argentina) population (95.44%) and the highest (99.90%) in Macao (China). Pairwise haplotype analysis showed the relative homogeneity of the Iberian origin samples, in accordance with what was previously found in the European populations for other Y-STR haplotypes (http://www.ystr.org). As expected, the four non-Caucasian samples, Macao (Chinese), Mozambique (Africans), Costa Rica (Africans) and Argentina (Lara, Amerindians), show highly significant Phist values in the pairwise comparisons with all the Caucasian samples.  相似文献

Although it is difficult for local governments to give support for social welfare recipients top political priority, there are huge variations in the support recipients actually receive among Norwegian municipalities. However, local governments representing different party ideologies may prefer to support different dimensions of generosity. Some municipalities could have a liberal attitude to eligibility rules but be strict on time limits and the amount of money provided. Others may be generous regarding time limits or amounts received once one is accepted as a welfare client. Data from the mid 1990s indicate the variation in support is related to different generosity dimensions for different party groups. While the total number of clients seems unrelated to politics and basically correlates with local social problems, the duration and amount of support are related to the political composition of the municipality assembly. Devoid of any large variation, both time limits and the amount of support increase in accordance with socialist leanings, and the total budget used for social welfare support also increases with the proportion of women in the municipality assembly.  相似文献

This study examined individual differences in the relations among preadolescents' sociomoral understanding and self-understanding, teacher and peer ratings of school behavior. Two hundred and thirty-nine preadolescents (M = 11.9 years; 127 girls and 112 boys) completed tasks concerning perceptions of competence, vocabulary, and peer-rated social competence. Students also participated in a story-telling interview that assessed sociomoral understanding and self-understanding. Results indicated links between various self-concept dimensions and (a) teacher ratings of academic competence, peer aggression (both physical and relational), and prosocial behavior; and (b) general vocabulary ability. Both sociomoral understanding and self-understanding were found to be linked to perceived academic competence for boys only. Independent of vocabulary ability, girls scored higher than boys on perceived behavioral conduct, teacher ratings of relational aggression (Grade 6 only), and self-understanding, particularly a sense of self-agency. Content analysis showed that girls were more likely than boys to refer to their parents when discussing their sense of self-agency. Independent of vocabulary ability, boys scored marginally higher than girls on sociomoral understanding. Results are discussed in terms of curricular implications for inter- and intrapersonal understandings.  相似文献

This article introduces some ideas about using internet classrooms to enrich the experience of those learning and teaching politics. It draws and reflects upon my three-year experience of using internet classrooms to teach politics in optional and compulsory politics undergraduate modules, providing critical evaluation of the successes and problems involved. Much of what the article discusses can be applied to most, if not all, politics modules and will be useful to those wishing to use new technologies to support active learning strategies in their undergraduate teaching. The article is based on personal experience and student evaluations, rather than any rigorous research of learning outcomes. As such, I do not set out to prove that using internet classrooms has pedagogical advantages over using only traditional methods, and I am not arguing a case for or against using either.  相似文献

In this paper, we determine how tax law and income distribution changes have separately contributed to the changes in tax progressivity over time, and also how a specific pre‐tax distribution of income affects the equalizing ability of a given tax change. We use information from the Current Population Survey for years that follow immediately after significant tax law changes or after the full enactment of these changes to measure the effect of income taxes on income distribution for selected years over the period 1978 to 1998. We find that, even when account is taken of the induced effect of changes in federal income tax laws on pre‐tax income, the individual income tax structure has been less successful in equalizing after‐tax income since the 1980s and into the early 1990s. We also find that a given tax law's equalizing effect on the distribution of income is significantly affected by the pre‐tax distribution of income. © 2005 by the Association for Public Policy Analysis and Management.  相似文献

Data from a national survey conducted in 1984 form the basis for a new analysis of anticandidate voting in presidential elections, i.e., voting focused more on a candidate one opposes than on a candidate one prefers. Anticandidate voting is viewed as the end product of a process whereby voters attempt to reduce discomfort that cross-pressures generate within their decision frameworks. In 1984, nearly a third of all likely voters said they were primarily motivated by a desire to voteagainst one of the two presidential candidates, a rate of anticandidate voting similar to that observed in the Johnson-Goldwater election of 1964 but well below that of the 1980 Reagan-Carter election. However, factors related to anticandidate voting in the past were not consistently linked to anticandidate voting in 1984. We conclude that the presence of Ronald Reagan exerted such a strong influence on the 1984 campaign that processes that would normally be observable, such as anticandidate voting, were overridden.  相似文献

The amount of control the general public exerts over government depends on accepted government procedures as determined by the political constitution and prevailing public opinion. It has not been the purpose of this paper to suggest ways of providing the public more control over government but to consider some implications of changes in that control. It is obvious that it would be desirable for the general public to have more control over political decisions; i.e., for the political process to be more responsive to the broad based benefits and costs that result from government action. The question is; what does more public control over government imply about the desirable size of government? For the natural rights advocate the answer is nothing. Government should be only large enough to protect citizens against force and fraud. The purpose of the present paper, however, has been to argue that the desirable size of government can be either positively or negatively related to the control exerted over it by the public. If this argument is accepted, it casts doubt on the possibility of a desirable minimum state.When there is little public control over government, organized special interest will have disproportionate political influence and will use this influence to expand government into activities that are detrimental to the public interest. Obviously, given this situation, it will be desirable to use additional public control over government to reduce the size of government by restricting its activities. But just as obvious is that this situation is one in which control over government is inadequate to the task of achieving a minimal state.  相似文献
