“...a theory of meaning for a particular language should be conceived by a philosopher as describing the practice of linguistic interchange by speakers of the language without taking it as already understood what it is to have a language at all: that is what, by imagining such a theory, we are trying to make explict." – Michael Dummer (2004: 31)  相似文献

A total of 2443 male individuals, previously typed for the 13 CODIS STR loci, distributed across the five North American population groups African American, Asian, Caucasian, Hispanic, and Native American were typed for the Y-STR loci DYS19, DYS385a/b, DYS389I/II, DYS390, DYS391, DYS392, DYS393, DYS437, DYS438 and DYS439 using the PowerPlex Y System. All population samples were highly polymorphic for the 12 Y-STR loci with the marker DYS385a/b being the most polymorphic across all sample populations. The Native American population groups demonstrated the lowest genetic diversity, most notably at the DYS393 and DYS437 loci. Almost all of the 12-locus haplotypes observed in the sample populations were represented only once in the database. Haplotype diversities were greater than 99.6% for the African Americans, Caucasians, Hispanics, and Asians. The Native Americans had the lowest haplotype diversities (Apaches, 97.0%; Navajo, 98.1%). Population substructure effects were greater for Y-haplotypes, compared with that for the autosomal loci. For the apportionment of variance for the 12 Y-STRs, the within sample population variation was the largest component (>98% for each major population group and approximately 97% in Native Americans), and the variance component contributed by the major population groups was less than the individual component, but much greater than among sample populations within a major group (11.79% versus 1.02% for African Americans/Caucasians/Hispanics and 15.35% versus 1.25% for all five major populations). When each major population is analyzed individually, the R(ST) values were low but showed significant among group heterogeneity. In 692 confirmed father-son pairs, 14 mutation events were observed with the average rate of 1.57x10(-3)/locus/generation (a 95% confidence bound of 0.83x10(-3) to 2.69x10(-3)). Since the Y-STR loci reside on the non-recombining region of the Y chromosome, the counting method is one approach suggested for conveying an estimate of the rarity of the Y-haplotype. Because the Y-STR loci are not all in disequilibrium to the same extent, the counting method is a very conservative approach. The data also support that autosomal STR frequencies can be multiplied by the upper bound frequency estimate of a Y-haplotype in the individual population group or those pooled into major population groups (i.e., Caucasian, African American, Hispanic, and Asian). These analyses support use of the haplotype population data for estimating Y-STR profile frequencies for populations residing in North America.  相似文献

主诉检察官制--司法独立的另一种诠释   总被引:1,自引:0,他引:1  
当代中国的司法改革呼唤着司法的真正、全面的独立.其中检察独立是具有中国特色司法独立的重要内容,而主诉检察官制度是检察独立中内部独立的有效形式.主诉检察官的独立性及其受制性揭示了中国司法独立的重要特色.主诉检察官制度应在司法独立的实现中逐步完善.  相似文献

Sixty proband children (P) of bipolar I parents and 60 control children of normal parents (C), in the age range 10–17, were investigated clinically by K-SADS-E interview and psychologically by personality inventories. In the global psychopathology rate of 63% in P children and 25% in C children, depressive disorders reached 8% in P children and 0% in C children, while depressive personality traits reached 22% in P children and 15% in C children. Cluster analysis evidenced a variety of personality structures, but 3 clusters were striking: a cluster characterized by high anxiety and depressive reactivity (17% P and 5% C children), a cluster characterized by high depressive reactivity and emotional instability (5% P children), and a hyperthymic cluster (5 % P children). Sixty-seven percent of P children and 36% of C children showed deviant personality traits (p<.01).  相似文献
