Selected AbstractsMolecular characterization of two nicotinic acetylcholine receptor subunits from Liposcelis bostrychophila Badonnel (Psocoptera: Liposcelididae)ARCHIVES OF INSECT BIOCHEMISTRY AND PHYSIOLOGY (ELECTRONIC), Issue 1 2009Pei-An Tang Abstract Two nicotinic acetylcholine receptor (nAChR) subunit genes, Lb,1 and Lb,8, were isolated and characterized from psocid, Liposcelis bostrychophila Badonnel, using the rapid amplification of cDNA ends (RACE) technique. They are the first two nAChR family members isolated from the insect order of Psocoptera. The full-length cDNAs of Lb,1 (GenBank accession number: EU871527) and Lb,8 (EU871526) consist of 2,025 and 1,763 nucleotides, respectively, and an open reading frame of 1,644 and 1,608,bp encoding 547 and 535 amino acid proteins, respectively. Both genes have typical features of nAChR family members, though they share only 56% identity in amino acid sequence. The dendrogram generated by the MEGA 3.1 program shows that the protein deduced by Lb,1 had the closest phylogenetic relationship to Agam,1 from Anopheles gambiae and Amel,1 from Apis mellifera, and Lb,8 shares the highest identity with Agam,8 from An. gambiae and Amel,8 from A. mellifera. Quantitative real-time PCR analysis showed that Lb,1 was expressed 2.03,6.54-fold higher than Lb,8 at the different developmental stages of L. bostrychophila. The highest expression levels of Lb,1 and Lb,8 were both detected at adult stage and the lowest were at the third and fourth nymphal stages, respectively. There was a stable and relatively low expression level for Lb,1, whereas there was a descending expression pattern for Lb,8 in the 1st through the 4th nymphal stadia. © 2009 Wiley Periodicals Inc. [source] Preparing the HR profession for technology and information workHUMAN RESOURCE MANAGEMENT, Issue 2-3 2004Paul S. Hempel Technology and human resource management have broad influences upon each other. Technology not only changes the administration of human resources (HR), which is the domain of e-HR, but also changes organizations and work. HR professionals must be able to adopt technologies that allow the reengineering of the HR function, be prepared to support organizational and work-design changes enabled by technology, and be able to support the proper managerial climate for innovative and knowledge-based organizations. An examination of HR professional degree programs shows that traditional HR education has poorly prepared the HR profession for these challenges. To address this shortfall, HR education must be revised to provide a greater focus on technological issues, and HR educators must acquire the skills needed to teach these courses. © 2004 Wiley Periodicals, Inc.

Our study of public policy programs shows that there are many challenges ahead in terms of making good decisions on the form and content of programs that will add value to governments and citizens. Appropriate choices in terms of program design and pedagogy will reflect different economic, social, environmental, and cultural influences and will be shaped by history, values, and the roles of public policy and management professionals within a particular governmental context. [source] Computing ripple effect for software maintenanceJOURNAL OF SOFTWARE MAINTENANCE AND EVOLUTION: RESEARCH AND PRACTICE, Issue 4 2001Sue Black Abstract Recent software maintenance models have included impact analysis and accounting for ripple effect as one of their stages. This paper describes and explains the reformulation of Yau and Collofello's ripple-effect algorithm and its validity within the software-maintenance process. Completely automatic computation of ripple effect has until now proved troublesome; we show how our approximation algorithm helps to overcome this. Our Ripple Effect and Stability Tool (REST) which uses our approximated algorithm to compute ripple effect for C programs, is described. Eleven C programs are used in an initial investigation into whether our approximated algorithm can replace Yau and Collofello's original algorithm for the purpose of automatic computation of ripple effect. The Pearson correlation coefficient for the two versions of the algorithm across the eleven programs shows a high correlation. Copyright © 2001 John Wiley & Sons, Ltd. [source] | ||||||||||
