The support of Hong Kong Chinese for democratic reform

This research paper has two major objectives. First, it explains the variations in public support for the British-led democratic reform in late June 1994. Second, it attempts to account for why the reform has only received mild rather than overwhelming backing from the local public. The significance of the research lies in the fact that according to comparative studies, public attitudes do shape democratic prospects. It shows that the low priority attached to democratic reform since the handover of Hong Kong can be better understood by referring to the basis of public support for the non-demoncratic political system before 1997. Models of political culture and rational choice are put to the test in comparing their explanatory power for public support of the British-led democratic reform and the rational choice model has been found to be more powerful. The social base of the political reform, as well as the political implications of the research are also discussed in this essay.

The effects of chemical and heat maceration techniques on the recovery of nuclear and mitochondrial DNA from bone

Forensic anthropologists use a number of maceration techniques to facilitate skeletal analysis of personal identity and trauma, but they may unwittingly eliminate valuable DNA evidence in the process. This study evaluated the effect of 10 maceration methods on gross bone structure and the preservation of DNA in ribs of 12 pigs (Sus scrofa). A scoring system was applied to evaluate the ease of maceration and resulting bone quality while DNA purity was quantified by optical densitometry analysis, followed by polymerase chain reaction (PCR) amplification of three mitochondrial and three nuclear loci. The results demonstrated that while mitochondrial DNA could be amplified for all experiments, cleaning treatments using bleach, hydrogen peroxide, ethylenediaminetetraacetic acid/papain, room temperature water and detergent/sodium carbonate followed by degreasing had low DNA concentrations and failed to generate nuclear PCR products. In general, treatments performed at high temperatures (90 degrees C or above) for short durations performed best. This study shows that traditionally "conservative" maceration techniques are not necessarily the best methods to yield DNA from skeletal tissue.     

Species identification of Kachuga tecta using the cytochrome b gene

A DNA technique has been established for the identification to species level of tortoises. The test on the shell of the animal was used to identify samples from the species Kachuga tecta. A total of 100 tortoise shell specimens collected from the National Council of Agriculture (COA), Taiwan, were used in this study. Primer pairs were designed to amplify partial DNA fragments of cytochrome b within the mitochondrial genome. The DNA data showed that among the 100 samples, there were four distinct haplotype DNA sequences, within which there were a total of 90 variable sites. Between haplotypes I and II, there was only 1 nucleotide difference at position 228. Between haplotypes I and III, 65 nucleotide differences were observed; haplotypes I and IV, 62 nucleotide differences; and haplotypes III and IV, 56 nucleotide differences were observed. There were 66 and 63 nucleotide differences between haplotypes II and III and haplotypes II and IV respectively. All four haplotypes were compared with the DNA sequences held at the GenBank and EMBL databases. The most similar species were K. tecta (haplotype I and II), Morenia ocellata (haplotype III) and Geoclemys hamiltonii (haplotype IV), and their respective mtDNA similarities were 99.5%, 99.3%, 89.9% and 99.5%. However, as haplotype III was only 89.9% homologous with M. ocellata, it would seem that this haplotype shows only a limited relationship with a similar species registered currently in these databases. The method established by this study is an additional method for the identification of samples protected under Convention International Trade in Endangered Species (CITES) and will improve the work for the preservation of the endangered species.
