Deconstructing decentralization in China: fiscal incentive versus local autonomy in policy implementation

This article examines the congruent and conflicting effects of fiscal decentralization and power devolution—two main types of decentralization in post‐reform China—in order to tackle the insufficient distinction between them in current academic analyses. Derived from the two types of decentralization respectively are fiscal incentive and local autonomy, which influence local states' policy implementation in turnover taxation. By uncovering the unique logic of either factor, this article argues that contrary to what is widely presupposed, local autonomy is not necessarily congruent with fiscal incentive in affecting local compliance with centrally imposed policy rules during policy implementation. When power devolution and fiscal decentralization follow an internally consistent logic of decentralization as a whole by proceeding at the same pace and favoring the same specific locality, they inevitably generate conflicting effects on local states' implementation strategies. Congruent effects arise only if incoherent evolution occurs between the two types of decentralization. This paradox highlights the contradiction inveterate in the dynamics of decentralization. This argument is first developed through theoretical reasoning, and then substantiated by an empirical comparison between Guangzhou and Shanghai during 1984–1988 and 1992–1995.     

Polymorphism of 17 Y-STR loci in Taiwan population

Haplotypes and allele frequencies of 17 Y-STRs included in the AmpFlSTR((R)) Yfilertrade mark kit (DYS19, DYS385, DYS389 I, DYS389 II, DYS390, DYS391, DYS392, DYS393, DYS437, DYS438, DYS439, DYS448, DYS456, DYS458, DYS635, Y GATA H4) were examined in a population sample of 200 unrelated Taiwanese males living in Taiwan.     

Evaluation of the DNA stability of forensic markers used in betel-quid chewers' oral swab samples and oral cancerous specimens: implications for forensic application

Chewed betel-quid (BQ) residues are often considered vital biological evidence at crime scenes, since the human DNA extracted from the residues is actually from buccal epithelial cells and can be associated with suspects. BQ-chewing is also a risk factor for oral diseases and/or cancers. Archived medical oral-specimens can be used to identify specific individuals under adverse conditions, although STR markers are known to be unstable in various tumor tissues. This study evaluates the DNA stability of forensic marker systems in BQ-chewers' oral epithelial cells, and in archived clinical specimens of oral cancer patients. The genotypes of oral and paired peripheral blood samples in 200 subjects were compared, using the commercialized typing systems of HLA-DQA1, PM (including LDLR, GYPA, HBGG, D7S8, and GC loci), and AmpFlSTR markers (including 9 STR loci and the Amelogenin gene). The 100 healthy BQ-chewers had consistent oral swab and paired blood sample genotypes analyzed withboth DQA1/PM and STR marker systems. In the 100 oral cancer patients, one discordant result at D7S8 was found in the 600DQA1/PM-marker loci, and 25 allelic alterations with expansion or contraction were detected in the 900 STR loci. The findings herein suggest that when cancerous specimens were tested, the HLA-DQA1/PM system with point polymorphism appears more reliable than the STR system with length polymorphism. Our results also indicate that healthy BQ-chewers' oral cotton swabs containing buccal epithelial cells are useful for forensic purposes using the HLA-DQA1, PM, and STR marker systems.     

Extraction of human DNA for PCR from chewed residues of betel quid using a novel "PVP/CTAB" method

Residues of chewed betel quid (BQ) are often found on crime scenes in Taiwan and possibly some of the Southeast Asian countries. Although these residues are important biological evidences relating to the suspects, the forensic analysis of BQ evidence has been hindered by failures in extraction of human DNA for PCR analysis. Therefore, it is a prerequisite for relevant forensic casework to establish a reliable method for extracting DNA from chewed BQ residues. Three conventional methods (salt/chloroform, 5% Chelex-100 resin, and QIAamp) were first tested for extraction of human DNA from 33 mock BQ samples, which had been stored for less than two months, and 50 four-year-old forensic BQ samples. PCR amplifications from the HLA-DQA1&PM and the STR loci were then used to test the quality of the extracted DNA. For the mock samples, three observations were made. First, PCR amplification of DNA extracted by using these conventional methods had low success rate. Second, the addition of extra Taq DNA polymerase could compensate the lost enzyme activities due to putative inhibitors and, thus, increase the yield. Third, using the Centricon-100 column to remove putative inhibitors substantially improved the efficiency of PCR. However, for the four-year-old forensic BQ samples, none of the attempts for PCR were successful. In order to solve the problem in PCR analysis of DNA from old BQ samples, we developed a DNA extraction method based on the use of polyvinyl pyrrolidone (PVP) and cetyltrimethylammonium bromide (CTAB), which bind to two common classes of PCR inhibitors in plants, polyphenols, and polysaccharides, respectively. The result showed that this "PVP/CTAB" method is completely successful for the mock BQ samples, and 92% (46 out of 50) successful for the four-year-old forensic BQ samples. To our best knowledge, this is the first report of a reliable method for the extraction of human DNA for PCR from chewed BQ residues. This method should provide a useful means for forensic identification in countries where betel chewing is common.     

Splitting and making parties: Analysis of party reconfiguration in Taiwan

The development of Taiwanese party politics reached a milestone in the 2000 presidential and 2001 legislative elections. The island's pre-existing three-party system underwent a marked reconfiguration. With the split of the Kuomintang (KMT), two new parties emerged but one existing party nearly collapsed. Party politics in Taiwan have shown a continuous process of proliferation of new parties. This paper analyzes the underlying logic that drives the reconfiguration of the Taiwanese party system. A political-institution perspective is employed to show how social cleavages, mixed electoral incentives, and government formation work in dictating the transformation of the party system. This paper is supported by the National Science Council, Taiwan, under Grant NSC 92-2414-H-001-019, NSC 93-2414-H-001-002, and NSC 94-2414-H-001-012.     

A Situational Model of Displacement and Diffusion Following the Introduction of Airport Metal Detectors

Much of the discourse surrounding counterterrorism centers on the inevitability of displacement, or the substitution of another form of terrorist attack in place of the one that has been thwarted. Yet a longstanding tradition of research in situational crime prevention finds that displacement is far from inevitable, and often depends crucially on the specific features of the incidents in question. In fact, crime prevention efforts are often followed by a “diffusion of benefits” (i.e., crime reductions) to incidents, groups, or locations that were not the intended target of the intervention. The current study examines various forms of displacement and diffusion in response to airport metal detectors among terrorist groups that had been involved in the perpetration of aviation attacks prior to their implementation. Using data from the Global Terrorism Database, the findings from interrupted time series models suggest a complex set of displacement and diffusion effects with respect to alternative attack modes, target types, and weapon usage.
