The term strategy is appearing with great frequency in the political marketing literature. However, the concept of political marketing strategy has been criticized for being unidimensional, ill‐defined and neglecting the contingencies of strategy theories. This article argues that a minimal definition and a division of epistemological terms could respond to the outlined critique. Copyright © 2011 John Wiley & Sons, Ltd. 相似文献

Six commercial preparations of human genomic DNA were quantified using five quantification methods: UV spectrometry, SYBR-Green dye staining, slot blot hybridization with the probe D17Z1, Quantifiler™ Human DNA Quantification kit and RB1 rt-PCR. All methods measured higher DNA concentrations than expected based on the information by the manufacturers. UV spectrometry, SYBR-Green dye staining, slot blot and RB1 rt-PCR gave 39, 27, 11 and 12%, respectively, higher concentrations than expected based on the manufacturers’ information. The DNA preparations were quantified using the Quantifiler™ Human DNA Quantification kit in two experiments. The measured DNA concentrations with Quantifiler were 125 and 160% higher than expected based on the manufacturers’ information. When the Quantifiler™ human DNA standard (Raji cell line) was replaced by the commercial human DNA preparation G147A (Promega) to generate the DNA standard curve in the Quantifiler™ Human DNA Quantification kit, the DNA quantification results of the human DNA preparations were 31% higher than expected based on the manufacturers’ information. The results indicate a calibration problem with the Quantifiler™ human DNA standard for its use with the Quantifiler™ Human DNA Quantification kit. The possible reasons for the problem are discussed and a solution is suggested. The results emphasise the need for standard reference DNA material and standard methods for DNA quantification. 相似文献

Two theoretical perspectives have been advanced to account for heightened egocentrism during early adolescence. One perspective assumes that formal operational thought is associated with increased self-consciousness. The second perspective proposes that parental support and affection diminish egocentrism, while parental rejection enhances self-conscious reactions by young adolescents. Data analysis using responses from 251 early adolescents (131 males, 120 females) on measures of cognitive development and perceived parental support revealed that (a) formal operations diminished adolescent egocentrism, while (b) perceived parental relations were predictive of self-consciousness. Contrary to posttheoretical assumptions, seventh graders functioning at the level of concrete operations were higher in self-conscious egocentrism than were formal-operations youths. Further, perceived parental support was associated with diminished egocentrism, while perceived parental rejection was predictive of heightened self-consciousness.Her research interests focus on early adolescent development.His research interests focus on personality and social development during adolescence.His research interests focus on clinical and counseling psychology and psychotherapy. 相似文献

Analysis of artificially degraded DNA using STRs and SNPs--results of a collaborative European (EDNAP) exercise 总被引:4,自引:0,他引:4
Dixon LA Dobbins AE Pulker HK Butler JM Vallone PM Coble MD Parson W Berger B Grubwieser P Mogensen HS Morling N Nielsen K Sanchez JJ Petkovski E Carracedo A Sanchez-Diz P Ramos-Luis E Briōn M Irwin JA Just RS Loreille O Parsons TJ Syndercombe-Court D Schmitter H Stradmann-Bellinghausen B Bender K Gill P 《Forensic science international》2006,164(1):33-44
Recently, there has been much debate about what kinds of genetic markers should be implemented as new core loci that constitute national DNA databases. The choices lie between conventional STRs, ranging in size from 100 to 450 bp; mini-STRs, with amplicon sizes less than 200 bp; and single nucleotide polymorphisms (SNPs). There is general agreement by the European DNA Profiling Group (EDNAP) and the European Network of Forensic Science Institutes (ENFSI) that the reason to implement new markers is to increase the chance of amplifying highly degraded DNA rather than to increase the discriminating power of the current techniques. A collaborative study between nine European and US laboratories was organised under the auspices of EDNAP. Each laboratory was supplied with a SNP multiplex kit (Foren-SNPs) provided by the Forensic Science Service, two mini-STR kits provided by the National Institute of Standards and Technology (NIST) and a set of degraded DNA stains (blood and saliva). Laboratories tested all three multiplex kits, along with their own existing DNA profiling technique, on the same sets of degraded samples. Results were collated and analysed and, in general, mini-STR systems were shown to be the most effective. Accordingly, the EDNAP and ENFSI working groups have recommended that existing STR loci are reengineered to provide smaller amplicons, and the adoption of three new European core loci has been agreed. 相似文献

In this study, forensic cases involving the use of Gamma Hydroxy Butyric acid (GHB) from the second half of 1999 through the second half of 2001 in The Netherlands (blood >5mg/l and urine >10mg/l) are described. GHB was analysed by GC-MS after lactone formation and using GHB-d6 as internal standard. The results are divided into three groups: cases of chemical submission, cases of driving under the influence and cases of unknown causes of death.GHB was found in six cases of possible chemical submission. In these cases, relatively low concentrations of GHB were found. The results show that in cases of chemical submission, urine should be analyzed, because GHB is present longer in urine than in blood. The police should collect the samples in containers that do not contain citrate as anticoagulant. Especially at low levels of GHB, the formation of GHB in these tubes hampers an interpretation of the results.GHB was found in 13 cases of driving under the influence. In contrast to the cases of chemical submission, high concentrations of GHB were found, corresponding with observations of extreme sleepiness or temporary loss of consciousness.GHB was found in 16 cases of unexplained death: the measured range of GHB concentrations in blood might correspond to effects such as drowsiness, but not to serious toxicity of GHB. In 4 of these 16 cases, the role of GHB could be excluded. In the remaining cases, the role of GHB remains unclear; more research into "background" concentrations of GHB in post-mortem material is required.The incidence of the use of GHB in The Netherlands cannot be derived from these toxicological data. As GHB is not routinely found during systematical toxicological analyses, these data may seriously underestimate the use of GHB. Therefore, information from the police to the forensic institute is essential. 相似文献

In commenting on ‘Decentralization, Local Governance and ‘Recentralization’ in Africa’ (Wunsch, 2001 ), this article concurs with the general thesis of Wunsch that the actual implementation as distinct from the rhetoric of decentralization in Africa has featured lingering central retention of power and resources and that genuine local control over important services and investments remains elusive. However, there is evidence that this is not invariably the case and that donors may have decisive roles to play in encouraging local assertiveness in the medium term in providing leverage for change through budget support and technical assistance to civic education, training local councillors, monitoring local government elections and encouraging local government associations to put to the test the national commitment to genuine local governance. These roles include helping to ensure the transparency of central transfers and, as in Uganda and Malawi for example, assisting with the development of intermediary fiscal mechanisms in this regard. Learning from such promising experiences will be vital in nurturing the longer term optimism heralded by Wunsch. Copyright © 2002 John Wiley & Sons, Ltd. 相似文献
