RASTtk: A modular and extensible implementation of the RAST algorithm for building custom annotation pipelines and annotating batches of genomes

Abstract: The RAST (Rapid Annotation using Subsystem Technology) annotation engine was built in 2008 to annotate bacterial and archaeal genomes. It works by offering a standard software pipeline for identifying genomic features (i.e., protein-encoding genes and RNA) and annotating their functions. Recently, in order to make RAST a more useful research tool and to keep pace with advancements in bioinformatics, it has become desirable to build a version of RAST that is both customizable and extensible. In this paper, we describe the RAST tool kit (RASTtk), a modular version of RAST that enables researchers to build custom annotation pipelines. RASTtk offers a choice of software for identifying and annotating genomic features as well as the ability to add custom features to an annotation job. RASTtk also accommodates the batch submission of genomes and the ability to customize annotation protocols for batch submissions. This is the first major software restructuring of RAST since its inception.

Isolation by distance, web service

Abstract: The population genetic pattern known as "isolation by distance" results from spatially limited gene flow and is a commonly observed phenomenon in natural populations. However, few software programs exist for estimating the degree of isolation by distance among populations, and they tend not to be user-friendly. We have created Isolation by Distance Web Service (IBDWS) a user-friendly web interface for determining patterns of isolation by distance. Using this site, population geneticists can perform a variety of powerful statistical tests including Mantel tests, Reduced Major Axis (RMA) regression analysis, as well as calculate F ST between all pairs of populations and perform basic summary statistics (e.g., heterozygosity). All statistical results, including publication-quality scatter plots in Postscript format, are returned rapidly to the user and can be easily downloaded. IBDWS population genetics analysis software is hosted at http://phage.sdsu.edu/~jensen/ and documentation is available at http://www.bio.sdsu.edu/pub/andy/IBD.html . The source code has been made available on Source Forge at http://sourceforge.net/projects/ibdws/ .

The role of transformational leadership in enhancing organizational innovation: Hypotheses and some preliminary findings

Abstract: A wide range of factors has been found to affect organizational innovation. Of these, top managers' leadership style has been identified as being one of the most, if not the most, important. Yet, few studies have empirically examined the link between this factor and innovation at the organizational level. This study builds on the extant literature to propose four hypotheses about how top managers' leadership styles directly and indirectly (via empowerment and organizational climate) affect their companies' innovation. A multisource approach is used to collect survey data from 32 Taiwanese companies in the electronics/telecommunications industry. The findings support a direct and positive link between a style of leadership that has been labeled as “transformational” and organizational innovation. They also indicate that transformational leadership has significant and positive relations with both empowerment and an innovation-supporting organizational climate. The former is found to have a significant but negative relation with organizational innovation, while the latter has a significant and positive relationship. The implications of the findings and possible directions for future research are discussed.
