This article assesses the employment situation in the U.S. information technology (IT) industry, examining recent job growth trends and the underlying factors, such as flexible staffing arrangements and offshore outsourcing, which are responsible for falling IT employment. The IT industry, which was at the center of the 1990s boom, was caught in the midst of the 2001 recession and the ensuing jobless recovery. Employment has fallen dramatically between March 2001 and March 2004 and the IT industry lost approximately 403,000 jobs, more than half of which were eliminated during the economic recovery. While cyclical factors are partially responsible for these employment declines, underlying weaknesses in IT labor markets remain as U.S. corporations continue to pursue restructuring tactics aimed at achieving immediate reductions in labor costs.

Codon usage bias (CUB) is defined as the selective and nonrandom use of synonymous codons by the organism for encoding the amino acids. One of the important plant transcription factor family is the ‘WRKY’ whose role has been investigated in the regulation of abiotic and biotic stress responses in plants. In this paper, the codon usage pattern of the WRKY transcription factor of the two important plant species Arabidopsis thaliana and Brassica rapa has been investigated. Various codon usage indices like ENc, CAI, correspondence analysis, RSCU analysis, neutrality plot and hierarchial clustering has been done. The GC codon status was high in Arabidopsis. The RSCU analysis of codons revealed that codons coding for arginine was maximum in both the plant species.Our results propose that natural selection was the main dominating factor guiding the evolution of different WRKY genes in both Arabidopsis thaliana and Brassica rapa.
