Detection of gunpowder stabilizers with ion mobility spectrometry

This study is the first reported ion mobility detection of ethyl centralite and diphenylamine (DPA) smokeless gunpowder stabilizers, together with the nitroso and nitro derivatives of diphenylamine. First, the applicability of the ion mobility spectrometry (IMS) for the substances of interest was determined. The existence of numerous peaks, both in positive and negative modes, clearly demonstrates the success of these experiments. All mono and di-nitro derivatives of DPA tested were detected with this method. Unfortunately, many of the ions generated were not accurately identified. However, reduced mobility constants representative of each ion generated under defined operating conditions could be used for purpose of compound identification. The method was then successfully tested on real gunpowder samples. By the use of IMS, we managed to establish a rapid, simple and sensitive screening method for the detection and identification of smokeless gunpowder organic components.     

Does Membership on the UN Security Council Influence Voting in the UN General Assembly?

Recent studies report that temporary members of the UN Security Council receive favorable treatment from the IMF, the World Bank, or in US foreign aid in exchange for their political support for permanent members. Nevertheless, few studies have examined whether this favorable treatment and these benefits have actually made any significant changes in the member states’ voting behavior in the United Nations. To explore this question, we investigate whether membership on the UN Security Council influences a state’s voting in the UN General Assembly. In the analysis of panel data for 197 countries over the period from 1946 to 2008, the empirical results show that elected members of the UN Security Council tend to behave similarly with permanent members, especially with the United States, as the number of loan programs signed with the IMF and the World Bank increases. Also, US foreign aid significantly increases temporary members’ vote coincidence with the United States and other permanent members. In this regard, this article contributes to our understanding of state voting behavior and power politics in international organizations.     

Motherless case in paternity testing

In paternity test using the DNA evidence, the analysis of the deficient case that the DNA profiles of mother or alleged father are not available is different from that of the trio case analyzed routinely. However, the motherless case that the genotypes of mother is not available has been requested and analyzed like the trio case. In this paper, we compared the motherless case and the trio case through the mean exclusion chance describing the probability of exclusion for a genetic marker system and the distribution of the probability of paternity calculated using the three current methods. We have also shown a case which can be falsely discriminated if it were requested in the analysis of the motherless case, and conclude that the analysis of the motherless case should be carefully conducted and the level for the discrimination should be different from that of the trio case.     

Allele frequencies of 15 STR loci using AmpF/STR Identifiler kit in a Korean population

The genetic variations for 15 short tandem repeat (STR) loci D8S1179, D21S11, D7S820, CSF1PO, D3S1358, TH01, D13S317, D16S539, D2S1338, D19S433, vWA, TPOX, D18S51, D5S818 and FGA were performed on 231 unrelated Korean population using commercially available AmpF/STR Identifiler kit.     

Sequences of the Cytochrome C Oxidase Subunit I (COI) Gene are Suitable for Species Identification of Korean Calliphorinae Flies of Forensic Importance (Diptera: Calliphoridae)

Abstract:  Calliphorinae fly species are important indicators of the postmortem interval especially during early spring and late fall in Korea. Although nucleotide sequences of various Calliphorinae fly species are available, there has been no research on the cytochrome c oxidase subunit I (COI) nucleotide sequences of Korean Calliphorinae flies. Here, we report the full-length sequences of the COI gene of four Calliphorinae fly species collected in Korea (five individuals of Calliphora vicina , five Calliphora lata , four Triceratopyga calliphoroides and three Aldrichina grahami ). Each COI gene was amplified by polymerase chain reaction and directly sequenced and the resulting nucleotide sequences were aligned and analyzed by MEGA4 software. The results indicate that COI nucleotide sequences can be used to distinguish between these four species. Our phylogenetic result coincides with recent taxonomic views on the subfamily Calliphorinae in that the genera Aldrichina and Triceratopyga are nested within the genus Calliphora .     

Public entrepreneurship and organizational performance in Asia: Do entreprneurial leadership,ethical climate and Confucian values matter in Korea and China

This is an empirical study on the effects of Confucian values and entrepreneurial leadership on public entrepreneurship and organisational performance in Asia based on data collected from China and South Korea. This study focuses on the differences in the effects of Confucian values, entrepreneurial leadership, and ethical climate on public entrepreneurship and organisational performance between government agencies in South Korea and China. Contrary to the conventional Western perspective, this study shows that Confucian values are not necessarily negatively associated with public entrepreneurship and organisational performance. Entrepreneurial leadership and public entrepreneurship (as a mediating variable) appear to be significant factors to organisational performance. The similarities and differences between China and South Korea are discussed.     

Senkaku/Diaoyu Islands Dispute and Taiwan’s Netizens’ Sentiments Toward Japan and China

The Sichuan Earthquake and the Heavenly Mandate: legitimizing Chinese rule through disaster discourse

In the aftermath of the 2008 Sichuan earthquake, the Chinese authorities launched a major public relations campaign to relay positive images of their relief effort and strengthen their political legitimacy. The effect has been a proliferation of symbols and political statements related to the disaster, not only in the official media, but also in cultural products such as movies or mass-media events. The earthquake has become part of the discourse of suffering, struggle, solidarity and ultimately victory. This article examines the ways in which various cultural products present the Sichuan earthquake and asks what meanings national crises have in the Chinese discourse on political legitimacy. The article analyses two cases: Chinese film, here in the form of Feng Xiaogang's blockbuster Aftershock, and performance-based discourses during the Beijing Olympics, the PRC's 60-Year Anniversary and the Shanghai Expo. By conducting a discourse analysis, we show how the earthquake has become part of a recurring discursive formation that is used by state and non-state actors alike to legitimate China's developmental model. Within this discourse, the leadership of the Party, the mastery of free markets and a revamped version of the Confucian idea of benevolent rule are marshaled as the decisive factors for winning any ‘battle’.
