Identity and security in Korea

The summit meeting between the two Korean heads of state, which took place in Pyongyang in June 2000, constitutes a major turning point in the peninsula's history. As the effects of the meeting are gradually unfolding, a period of detente no longer seems impossible. But major difficulties remain unsolved and Korea will continue to be one of the world's most volatile areas. The task of this essay is to identify and analyse some of the entrenched political patterns that will challenge policy-makers in the years ahead. To do so it is necessary to portray the conflict in Korea not only in conventional ideological and geopolitical terms, but also, and primarily, as a question of identity. From such a vantage-point two components are essential in the search for a more peaceful peninsula. Substantial progress has recently been made in the first realm, the need to approach security problems, no matter how volatile they seem. in a cooperative and dialogical, rather than merely a coercive manner. The second less accepted but perhaps more important factor, revolves around the necessity to recognize that dialogue has its limits, that the party on the other side of the DMZ cannot always be accommodated or subsumed into compromise. Needed is an ethics of difference: a willingness to accept that the other's sense of identity and politics may be inherently incompatible with one's own.

Equity in regional service provision

Most transportation agencies stipulate that an important planning goal is to provide equitable and just public transport services. However, who is to be served and the type of service that should be provided has been ambiguous. This paper develops a methodology for examining equity in the provision of public transportation services. An approach for identifying areas in need of public transport is developed based upon the use of socio-demographic and economic information. Public transport need is then related to levels of access to service. This approach makes it possible to establish the degree to which public transport services may be considered equitable in relation to need and suitable access. A detailed analysis of the southeast Queensland region of Australia illustrates how this approach may be used to inform public transport decision making.

Descriptions of the Anopheles (Cellia) farauti complex of sibling species (Diptera : Culicidae) in Australia

Descriptions of the three sibling species of the Anopheles farauti complex in Australia, A. farauti Laveran (formerly A. farauti No. 1), A. hinesorum Schmidt sp.n. (formerly A. farauti No. 2) and A. torresiensis Schmidt sp.n. (formerly A. farauti No. 3) are provided. These species form a part of the punctulatus group, which contains the major malaria vectors in the southwest Pacific. Morphological markers are described for adult females, fourth instar larvae and pupae which identify most specimens, and are presented in keys.

Vps45p stabilizes the syntaxin homologue Tlg2p and positively regulates SNARE complex formation

Sec1p-like/Munc-18 (SM) proteins bind to t-SNAREs and inhibit ternary complex formation. Paradoxically, the absence of SM proteins does not result in constitutive membrane fusion, Here, we show that in yeast cells lacking the SM protein Vps45p, the t-SNARE Tlg2p is down-regulated, to undetectable levels, by rapid proteasomal degradation. In the absence of Vps45p, Tlg2p can be stabilized through abolition of proteasome activity. Surprisingly, the stabilized Tlg2p was targeted to the correct intracellular location. However, the stabilized Tlg2p is non-functional and unable to bind its cognate SNARE binding partners, Tlg1p and Vti1p, in the absence of Vps45p, A truncation mutant lacking the first 230 residues of Tlg2p no longer bound Vps45p but was able to form complexes with Tlg1p and Vti1p in the absence of the SM protein. These data provide us with two valuable insights into the function of SM proteins. First, SM proteins act as chaperone-like molecules for their cognate t-SNAREs, Secondly, SM proteins play an essential role in the activation process allowing their cognate t-SNARE to participate in ternary complex formation.

Mouse Sox8 is located between, not within, the t-complex deletions t(w18) and t(h20) on chromosome 17

The SOX family of developmental transcription factors is known to play critical roles in cell lineage specification, fate determination and differentiation during development in diverse phyla. Their importance is underscored by their involvement in a number of human diseases and mouse mutants, and by targeted mutation in mice. SOX8 is broadly expressed during development and is located on human chromosome 16p and within the t-complex on mouse chromosome 17, in the vicinity of two mutations t(w18) and t(h20). Here we analyse mutant genomic DNA to show that the Sox8 gene locus lies outside the deletion regions of both t(w18) and t(h20) and between these deletions. These data exclude Sox8 from contributing to the t(w18) and t(h20) phenotypes, and provide an additional marker for structural characterization of this complex genomic region. Copyright (C) 2001 S.

Securing the commercial internet: Lessons learned in developing a postgraduate course in information security management

This paper describes the inception, planning and first delivery of a security course as part of a postgraduate ecommerce program. The course is reviewed in terms of existing literature on security courses, the common body of knowledge established for security professionals and the job market into which students will graduate. The course described in this paper is a core subject for the e-commerce program. This program was established in 1999 and the first batch of students graduated in 2001. The program is offered at both postgraduate and undergraduate level. The work described here relates to the postgraduate offering. Students on this program are graduates of diverse disciplines and do not have a common e-commerce or business background.

Complementation analysis of the flavivirus Kunjin NS3 and NS5 proteins defines the minimal regions essential for formation of a replication complex and shows a requirement of NS3 in cis for virus assembly

We have previously reported successful trans-complementation of defective Kunjin virus genomic RNAs with a range of large lethal deletions in the nonstructural genes NSI, NS3, and NS5 (A. A. Khromykh et al., J. Virol. 74:3253-3263, 2000). In this study we have mapped further the minimal region in the NS5 gene essential for efficient trans-complementation of genome-length RNAs in repBHK cells to the first 316 of the 905 codons. To allow amplification and easy detection of complemented defective RNAs with deletions apparently affecting virus assembly, we have developed a dual replicon complementation system. In this system defective replicon RNAs with a deletion(s) in the nonstructural genes also encoded the puromycin resistance gene (PAC gene) and the reporter gene for beta-galactosidase (beta-Gal). Complementation of these defective replicon RNAs in repBHK cells resulted in expression of PAC and beta-Gal which allowed establishment of cell lines stably producing replicating defective RNAs by selection with puromycin and comparison of replication efficiencies of complemented defective RNAs by beta-Gal assay. Using this system we demonstrated that deletions in the C-terminal 434 codons of NS3 (codons 178 to 611) were complemented for RNA replication, while any deletions in the first 178 codons were not. None of the genome-length RNAs containing deletions in NS3 shown to be complementable for RNA replication produced secreted defective viruses during complementation in repBHK cells. In contrast, structural proteins produced from these complemented defective RNAs were able to package helper replicon RNA. The results define minimal regions in the NS3 and NS5 genes essential for the formation of complementable replication complex and show a requirement of NS3 in cis for virus assembly.
