The Political Economy of Border Checkpoints in Shadow Exchanges

ABSTRACT

This introductory article revisits cross-border shadow exchanges in a comparative perspective and reflects on their theoretical implications. It explores the diversities and complexities of shadow operations and critically examines the concept of informality that is commonly used to describe such non-state-sanctioned practices. It further underlines the key role played by checkpoint politics in border governance. Border checkpoints serve both as a state institution in regulating border crossings as well as a political site where material and power exchanges among state and non-state actors are negotiated. Such negotiation of selective passage through state-controlled gateways is often predicated upon the skilful manipulation of time and space by experienced traders and brokers.     

Genetic analysis of 18 X-linked short tandem repeat markers in Korean population

The population genetic data of 18 X-chromosomal short tandem repeat (STR) markers DXS6807, DXS8378, DXS9895, DXS9902, DXS6810, DXS7132, DXS981, DXS6800, DXS9898, DXS6789, DXS101, DXS6797, GATA172D05, GATA165B12, HPRTB, GATA31E08, DXS8377, and DXS7423 were analyzed in samples of unrelated 220 males and 181 females from Korean population. The exact test for genotype distribution of the markers showed no significant deviation from the Hardy-Weinberg equilibrium. Allele frequencies between male and female samples were not significantly different in all examined markers. All examined males and females showed different hemizygotic haplotype and combined genotypes, respectively. Four cases of mutation were found in GATA172D05, GATA31E08, DXS7132, and HPRTB from the analysis of 95 father-child-mother trios. Details of X chromosomal STRs in Koreans would be useful in paternity tests and forensic purposes as well as whole X-chromosomal mapping studies.     

Visas and work permits: Possible global negotiating initiatives

We discuss global options for initiatives intended to ameliorate adverse impacts of visa and work permit systems used by national governments around the world. We first describe and document some of their effects, noting the relative lack of other research work on these issues. We then discuss proposals for a new and supplemental global visa structure which have been made as part of the Mode 4 GATS negotiations in the WTO, suggesting that the GATS/WTO may be an imperfect institutional location for negotiating on these matters. We then evaluate other approaches, including what realistically could be possible if a new body specifically created for global negotiation in the area were to be used.

Exporting to China and ASEAN countries： Perceived advancement in marketing competencies and export performance

Malaysians firms have made inroads into the non-traditional export markets. Such ventures are expected to result in increased knowledge about the marketing systems that are posited to be different from the traditional export markets. This paper reports on the perceived improvement in marketing competencies of Malaysian exporters. The results of data analysis show that there are five dimensions of marketing competency. In ranking order, segmenting and targeting competency is ranked highest followed by product management, export management, product differentiation and promotion. Multiple regression analysis was performed to test the explanatory power of each marketing competency on export performance of firms exporting to China and ASEAN countries. The result revealed that none of the marketing competency explained the variation in export performance for the China market. However, among exporters in ASEAN countries, it was noted that promotion competency resulted in a negative impact on both measures of export performance. Product competency is positively associated with financial measure of export performance. Competencies in segmenting and targeting, and export management are positively associated with non-financial performance.     

纺织品配额的结束：东盟经济的启示

在2005年1月多边纤维协议终止以前,人们普遍担心小额纺织商、布匹生产商(包括那些在东南亚一些国家的生产商)将抵挡不住来自中国和印度市场的冲击。对于以纺织和服装为主要出口商品的国家,如柬埔寨、老挝、菲律宾、印度尼西亚尤其如此。在菲律宾,纺织和制衣产业是该国第二大出口创汇产业,可解决40万人的就业问题。在柬埔寨,纺织和服装产品则占了出口商品的87%,解决了20万人的就业问题。由于拥有大批廉价劳动力,中国在纺织和制衣方面的竞争优势已经对东盟国家的相关产业产生了一些冲击。然而,当大量的中国纺织和制衣产品输出到西方市场的时候…     

Transportation Access,Rental Vouchers,and Neighborhood Satisfaction: Evidence From the Moving to Opportunity Experiment

The Housing Choice Voucher (HCV) program is designed in part to expand the neighborhood choices of assisted households, thereby enabling assisted households to find a living environment that simultaneously meets their housing and neighborhood preferences. While several studies have examined the impact of rental subsidies on neighborhood satisfaction, few have examined whether access to adequate transportation enables HCV recipients to locate housing in more desirable locations. This article relies on data from the Moving to Opportunity experiment to examine the impact of transportation access, rental housing vouchers, and geographic constraints on neighborhood satisfaction. We find that access to both vehicles and public transit positively influences neighborhood satisfaction, and the influence of vehicle access varies with transit proximity. These findings point to the importance of transportation in helping low-income assisted renter households locate housing in more desirable neighborhoods.     

Roadside detection of impairment under the influence of ketamine--evaluation of ketamine impairment symptoms with reference to its concentration in oral fluid and urine

Although there are many roadside testing devices available for the screening of abused drugs, none of them can be used for the detection of ketamine, a popular abused drug in Hong Kong. In connection to local drug driving legislation, effective roadside detection of ketamine in suspected drug-impaired drivers has to be established. According to the drug evaluation and classification program (DEC), ketamine is classified in the phencyclidine (PCP) category. However, no study has been performed regarding the signs and symptoms exhibited by users under the influence of ketamine. In a study to develop a protocol for effective roadside detection of drug-impaired drivers, 62 volunteers exiting from discos were assessed using field impairment tests (FIT) that included measurements of three vital signs (i.e. body temperature, pulse rate and blood pressure), three eye examinations [pupil size, lack of convergence (LOC) and horizontal gaze nystagmus (HGN)] and four divided attention tests (Romberg, one-leg stand, finger-to-nose and walk-and-turn tests). Subsequent laboratory analysis of oral fluid and urine samples from the participants revealed the presence of common abused drugs in both the urine and oral fluid samples of 55 subjects. The remaining 7 subjects with no drug in their oral fluid samples were used as drug-free subjects. In addition, 10 volunteers from the laboratory who were regarded as drug-free subjects were also assessed using the same FIT. Among the 62 volunteers, 39 of them were detected with ketamine in their oral fluid. Of these ketamine users, 21 of them (54%) with only ketamine found in their oral fluid samples while the rest (18 subjects) of them had other drugs (i.e. MA, MDMA, benzodiazepines and/or THC) in addition to ketamine. Of the 21 ketamine-only users, 15 of them (71%) were successfully identified by FIT. It was found that when salivary ketamine concentrations were greater than 300 ng/mL, signs of impairment became evident, with over 90% detection rate using the FIT. By comparing the FIT observations on the 21 ketamine-only users with the drug-free subjects, the typical signs and symptoms observable for subjects under the influence of ketamine included LOC, HGN, elevated pulse rate and in general, failing the divided attention tests, especially the walk-and-turn and one-leg stand.     

Application of Micro‐Attenuated Total Reflectance Fourier Transform Infrared Spectroscopy to Ink Examination in Signatures Written with Ballpoint Pen on Questioned Documents

Questioned documents examined in a forensic laboratory sometimes contain signatures written with ballpoint pen inks; these signatures were examined to assess the feasibility of micro‐attenuated total reflectance (ATR) Fourier transform infrared (FTIR) spectroscopy as a forensic tool. Micro‐ATR FTIR spectra for signatures written with 63 ballpoint pens available commercially in Korea were obtained and used to construct an FTIR spectral database. A library‐searching program was utilized to identify the manufacturer, blend, and model of each black ballpoint pen ink based upon their FTIR peak intensities, positions, and patterns in the spectral database. This FTIR technique was also successfully used in determining the sequence of homogeneous line intersections from the crossing lines of two ballpoint pen signatures. We have demonstrated with a set of sample documents that micro‐ATR FTIR is a viable nondestructive analytical method that can be used to identify the origin of the ballpoint pen ink used to mark signatures.     

Optimization of Human mtDNA Control Region Sequencing for Forensic Applications

Sequencing mitochondrial DNA hypervariable regions I and II (HVI and HVII) is useful in forensic missing person and unidentified remains cases. Improvements in ease and sensitivity of testing will yield results from more samples in a timely fashion. Routinely, amplification of HVI and HVII is followed by Sanger sequencing using the BigDye^® Terminator v3.1 Cycle Sequencing kit (Applied Biosystems) using 4 μL of ready reaction mix (RRM). Each sequencing reaction is then purified through column filtration before capillary electrophoresis. Using lower amounts of RRM (2 μL or 1 μL) and purification using BigDye^® XTerminator^? (Applied Biosystems) instead of columns showed no loss of sequence length and increased the quality and the sensitivity of testing, allowing HVI and HVII typing from mitochondrial genome equivalent to 125 fg of nuclear DNA, or 100 pg of HVI/HVII amplicons. Using this methodology, testing can be completed in 1 day, and the cost of testing is reduced.
