The purpose of this paper is to derive crucial insights from multi-scale analysis to detect equity return co-movements between Korean and emerging Asian markets.

Wavelet correlation, wavelet coherence and wavelet clustering measures are used to uncover Korean equity market interactions which are hard to see using any other modern econometric method and which would otherwise had remained hidden.

The authors observed that Korean equity market is strongly integrated with Asian equity markets at lower frequency scales and has a relatively weak correlation at higher frequencies. Further this correlation eventually grows strong in the interim of crises period at lower frequency scales. The authors, however, do not found any significant deviation in dendrograms generated in data clustering process from wavelet scale 2 to 6 which are associated with four and 64 weeks period, respectively. Overall the findings are relevant and have strong policy and practical implications.

The unique contribution of this paper is that it introduces wavelet clustering analysis to produce a nested hierarchy of similar markets at each frequency level for the first time in finance literature

This paper seeks to investigate the use of engineering conference papers by examining where the papers presented at the Stapp Car Crash Conference from 1980‐2005 were subsequently cited. Also, to examine whether the references were made to the conference paper or to the individual, the SAE Technical Paper, the second publication method. It also aims to study whether the citations were made to the lead author or secondary authors.

The individual papers were searched in Science Citation Index on the Web of Science platform using the “Cited author” search and the appropriate work(s) were selected using the “Cited work” information. The number of citations to each paper was recorded and the bibliographic information from the citing articles for the “top cited” articles were retrieved and examined to determine the subject focus of the citing journals.

Almost two‐thirds of the papers from the Stapp Car Crash Conference were cited at least once, mirroring that of engineering journal articles. These citations appear in journals representing a wide variety of disciplines besides engineering including journals covering “clinical neurology”, “orthopedics”, “rehabilitation” and “surgery”. The majority of citations (92 per cent) were found to be to the lead author and approximately 85 per cent were cited as papers within the conference proceedings with the remaining papers cited as individual technical papers.

The results on the impact and use of engineering conference papers, especially the results in terms of author and material type, will provide valuable insight into this literature, providing librarians and researchers with a better understanding of their use in the advancement of research and scholarship.

Reports on the conference, "Ethics of Electronic Information in the 21st Century 20032, held in Tennessee, October 2003.

The librarian and researcher have to be able to uncover specific articles in their areas of interest. This Bibliography is designed to help. Volume IV, like Volume III, contains features to help the reader to retrieve relevant literature from MCB University Press' considerable output. Each entry within has been indexed according to author(s) and the Fifth Edition of the SCIMP/SCAMP Thesaurus. The latter thus provides a full subject index to facilitate rapid retrieval. Each article or book is assigned its own unique number and this is used in both the subject and author index. This Volume indexes 29 journals indicating the depth, coverage and expansion of MCB's portfolio.

The University of Houston Libraries are developing an expert system to assist library users in selecting appropriate indexes and abstracts to meet their information needs. This project, which is being conducted by the Intelligent Reference Systems Committee, is the first step in a broader plan to develop reference expert systems.

Outlines some of the presentations at the Electronic information in the 21st century (EEI21) symposium at the University of Memphis in October 2004. EEI21 is an internationally recognized ethics meeting attracting scholars, practitioners and students interested in a wide range of information ethics and related topics. The EEI21 tradition of thematic focus areas continued with intellectual property rights as the special topic for 2004.

Linking Florida's Natural History uses species information as the nexus for pulling together scientific data from museum specimen databases and library catalogs of scientific literature. The goals of the IMLS funded project were to integrate specimen records and bibliographic records about the same species; to create an interface equally easy for scientists, students and laymen to use; and to enhance bibliographic description to make it more usable in a taxonomic and environmental context. Although some development was required to enable Z39.50‐based broadcast search across bibliographic and specimen collections, the bulk of the work was devoted to identifying and overcoming inconsistencies between the resource description practices of libraries and museums. Enriching records with taxonomic and geographic information was also a challenge.

Density optimization is the first critical step in building additively manufactured parts with high-quality and good mechanical properties. The authors developed an approach that combines simulations and experiments to identify processing parameters for high-density Ti-6Al-4V using the laser powder-bed-fusion technique. A processing diagram based on the normalized energy density concept is constructed, illustrating an optimized processing window for high- or low-density samples. Excellent mechanical properties are obtained for Ti-6Al-4V samples built from the optimized window.

The authors use simple, but approximate, simulations and selective experiments to design parameters for a limited set of single track experiments. The resulting melt-pool characteristics are then used to identify processing parameters for high-density pillars. A processing diagram is built and excellent mechanical properties are achieved in samples built from this window.

The authors find that the laser linear input energy has a much stronger effect on the melt-pool depth than the melt-pool width. A processing diagram based on normalized energy density and normalized hatch spacing was constructed, qualitatively indicating that high-density samples are produced in a region when 1 < E* < 2. The onset of void formation and low-density samples occur as E* moves beyond a value of 2. The as-built SLM Ti-6Al-4V shows excellent mechanical performance.

A combined approach of computer simulations and selected experiments is applied to optimize the density of Ti-6Al-4V, via laser powder-bed-fusion (L-PBF) technique. A series of high-density samples are achieved. Some special issues are identified for L-PBF processes of Ti-6Al-4V, including the powder particle sticking and part swelling issues. A processing diagram is constructed for Ti-6Al-4V, based on the normalized energy density and normalized hatch spacing concept. The diagram illustrates windows with high- and low-density samples. Good mechanical properties are achieved during tensile tests of near fully dense Ti-6Al-4V samples. These good properties are attributed to the success of density optimization processes.

The Convention on Biological Diversity (CBD), set specific targets for halting biodiversity loss, including the need to establish 10 per cent of coastal/marine areas conserved through, among other things, well‐connected systems of protected areas by 2020. The reality is that whereas nearly 15 per cent of land is protected, just over 1 per cent of marine space is similarly protected. The challenge is to reach “a global representative system” of Marine Protected Areas (MPAs), recognizing that countries need to establish cooperative mechanisms at ecoregion level. The purpose of this paper is to address the options and trends for countries to develop transboundary cooperation through MPAs.

The authors address several case studies, focusing on political, governance and financing frameworks.

The main findings revealed that countries use MoU, MoA or Joint Declaration supported on international conventions as the WHC, Ramsar Convention and CMS. Governance models seem to include political/management/technical levels, with political decisions translated into action plans carried out by joint committees, supported by national institutions and scientific/technical boards. Also the involvement of civil society in management is a growing driving force. Financing transboundary MPAs is going through an evolutionary process, from an exclusive binomial national budgets/UNEP‐GEF to a wider financial net through ecotourism income and private donors.

The different solutions found point out myriad possibilities where transboundary cooperation is envisaged. States can benefit from the experiences already acquired to jointly achieve the target of protecting 10 per cent of the marine environment by 2020.
