On the basis of interviews, census data, and precinct-level electoral results from the October 2010 parliamentary election in Kyrgyzstan, this paper examines the influences on the party vote in Kyrgyzstan. Instead of traditional socioeconomic variables, this study finds that regionalism (North vs. South), ethnicity, personalism, and violence offered the most compelling explanations of party preference in Central Asia's most competitive election. The paper also examines the contextual factors that constructed and filtered voter demand, from Kyrgyzstan's political and economic conjuncture in 2010 to its unusual party system and electoral rules. 相似文献

Different national and international agencies have selected specific STR sets for forensic database use. To enhance database comparison across national and international borders, a 27‐locus multiplex system was developed comprising all 15 STR loci of the European standard set, the current 13 STR loci of the CODIS core, the proposed 22 STR loci of the expanded CODIS core, 4 additional commonly used STR loci, and the amelogenin locus. Development required iterative primer design to resolve primer‐related artifacts, amplicon sizing, and locus‐to‐locus balance issues. The 19.5‐min assay incorporated newly developed six‐dye chemistry analyzed using a novel microfluidic electrophoresis instrument capable of simultaneous detection and discrimination of 8 or more fluorescent dyes. The 27‐locus multiplex offers the potential for a new international STR standard permitting laboratories in any jurisdiction to use a single reaction to determine profiles for loci they typically generate plus an expanded common STR profiling set of global interest. 相似文献

Abstract: The time required for short tandem repeat (STR) amplification is determined by the temperature ramp rates of the thermal cycler, the components of the reaction mix, and the properties of the reaction vessel. Multiplex amplifications in microfluidic biochip-based and conventional tube-based thermal cyclers have been demonstrated in 17.3 and 19 min, respectively. Optimized 28-cycle amplification protocols generated alleles with signal strengths above calling thresholds, heterozygous peak height ratios of greater than 0.65, and incomplete nontemplate nucleotide addition and stutter of less than 15%. Full CODIS-compatible profiles were generated using the Profiler Plus ID, COfiler and Identifiler primer sets. PCR performance over a wide range of DNA template levels from 0.006 to 4 ng was characterized by separation and detection on a microfluidic electrophoresis system, Genebench-FX™ . The fast multiplex PCR approach has the potential to reduce process time and cost for STR analysis and enables development of a fully integrated microfluidic forensic DNA analysis system. 相似文献

This article investigates the cultural identities of adolescent immigrants in the pre-migration period and during the first
3 years after immigration. The target population consists of high-school Jewish adolescents from Russia and Ukraine participating
in an Israeli immigration program. In this program, Jewish adolescents immigrate to Israel without their parents, live in
kibbutzim and boarding schools, and study in Israeli schools. Participants filled out questionnaires four times: half a year
before their departure from the homeland and once a year for three consecutive years after their arrival to Israel. Changes
in the cultural identities during immigration were curvilinear. Three stages were distinguished: devaluation of the homeland
and idealization of the country of immigration in the pre-migration period, disillusionment with the receiving country and
strengthening of the homeland cultural identity in the first year after immigration, and the formation of an inconsistent
bi-cultural identity in the later post-migration period. Throughout the entire post-migration period, immigrants’ attitude
towards the receiving country was more positive than their attitude towards their homeland; however, immigrants’ sense of
belonging to the homeland was stronger than their sense of belonging to the receiving country. Pre-migration cultural identities
and perceived discrimination in the receiving country predicted post-migration cultural identities of immigrants. Immigrant
adolescents from ethnically homogenous Jewish families had a less positive attitude towards Russia/Ukraine, a more positive
attitude towards Israel, and a weaker sense of belonging to Russia/Ukraine as compared to immigrants from ethnically mixed
families.

Two studies evaluating cognitive-behavioral treatment programs for male spouse abusers are reported.3 Both programs resulted in significant reductions in both indirect and direct threats of violence and direct and severe violence towards spouses. Study 1 identified reduced levels of guilt proneness and increased levels of group conformity as a result of the intervention program. In addition, changes in attitudes toward love were noted from pre- to post-test indicating greater physical attraction, intensity of emotion, and commitment to the lover. Changes were maintained at a six month follow-up. Study 2 evaluated a modified cognitive-behavioral treatment formal that focused more on communication, problem-solving, and sexual attitudes and practices. All levels of violence were significantly reduced and changes in endorsement of sexual attitudes were noted. In addition, males showed lower levels of passive-aggressiveness and increasing levels of narcissism as a function of treatment. Implications for program development and research are discussed. 相似文献

This paper reexamines the competitive market solution to the determination of product safety. The concept of an optimizing social level of product safety-defined at the point at which the costs of increasing safety are equated to consumers willingness to pay for it-is developed and discussed. Various potential market failures are outlined. These failures give reasons to expect that the competitive solution will not be achieved in practice and provide a rationale for certain types of governmental intervention. Various empirical studies of implicit markets for various types of risks are reviewed as a basis for evaluating market efficiency and regulatory efficiency. 相似文献
