Impact of the Siena College Tech Valley Scholars Program on Student Outcomes

The experimental group for this study included 38 students who entered the Tech Valley Scholars (TVS) program over the course of three academic years, from 2009-10 through 2011-12. Two groups of controls were used: a randomly selected sample of STEM students who matriculated in the same time frame; and a matched sample. The TVS students and controls were compared on two primary outcome variables: graduation (or retention to senior year), and final cumulative GPA. The major findings of this study are that (1) the TVS students had better outcomes than both the randomly selected comparison group and the matched control group, (2) unmet financial need is an important risk factor for non-retention, (3) students with moderately high unmet need can be academically successful if retained, and (4) the TVS program is having a positive impact on at-risk students. Recommendations for effective and efficient allocation of scholarship funds are given and future statistical studies are recommended

Genes Associated with 2-Methylisoborneol Biosynthesis in Cyanobacteria: Isolation, Characterization, and Expression in Response to Light

The volatile microbial metabolite 2-methylisoborneol (2-MIB) is a root cause of taste and odor issues in freshwater. Although current evidence suggests that 2-MIB is not toxic, this compound degrades water quality and presents problems for water treatment. To address these issues, cyanobacteria and actinomycetes, the major producers of 2-MIB, have been investigated extensively. In this study, two 2-MIB producing strains, coded as Pseudanabaena sp. and Planktothricoids raciborskii, were used in order to elucidate the genetic background, light regulation, and biochemical mechanisms of 2-MIB biosynthesis in cyanobacteria. Genome walking and PCR methods revealed that two adjacent genes, SAM-dependent methyltransferanse gene and monoterpene cyclase gene, are responsible for GPP methylation and subsequent cyclization to 2-MIB in cyanobacteria. These two genes are located in between two homologous cyclic nucleotide-binding protein genes that may be members of the Crp-Fnr regulator family. Together, this sequence of genes forms a putative operon. The synthesis of 2-MIB is similar in cyanobacteria and actinomycetes. Comparison of the gene arrangement and functional sites between cyanobacteria and other organisms revealed that gene recombination and gene transfer probably occurred during the evolution of 2-MIB-associated genes. All the microorganisms examined have a common origin of 2-MIB biosynthesis capacity, but cyanobacteria represent a unique evolutionary lineage. Gene expression analysis suggested that light is a crucial, but not the only, active regulatory factor for the transcription of 2-MIB synthesis genes. This light-regulated process is immediate and transient. This study is the first to identify the genetic background and evolution of 2-MIB biosynthesis in cyanobacteria, thus enhancing current knowledge on 2-MIB contamination of freshwater

THE MEDIATING ROLE OF PROCEDURAL JUSTICE IN RESPONSES TO PROMOTION DECISIONS

ABSTRACT This study used structural equations modeling to examine the mediating role of procedural justice in the relationships between promotion decisions and organizational commitment and between promotion decisions and intent to leave the organization. 156 managers and executives in Italian subsidiaries of two large multinational organizations in the chemical industry were surveyed about their career history within the organization and their reactions to promotion decisions over an 8-year period. The results showed that promotion decisions influenced feelings of organizational commitment through perceptions of procedural justice in promotion decision-making processes. The theoretical and practical implications of the study s findings are discussed. Keyword procedural justice- promotion decisions- career
