The role played by the protein UnkG from the plant growth-promoting bacterium Pseudomonas putida UW4 in the ability of the bacterium to facilitate plant growth was studied. Previous work showed that over-expressing UnkG decreased the ability of P. putida UW4 to facilitate plant growth. In contrast, an unkG knock-out mutant of P. putida UW4 displayed an increased ability to promote plant growth. Various biological activities of P. putida UW4, P. putida UW4/pETP and P. putida UW4/pETP-unkG have been compared. Thus, the growth curves were measured; the Biolog™ system was used to test the ability of these strains to utilize various carbon sources; the strains were observed by scanning electron microscopy to assess their relative cell sizes; biochemical assays were conducted to quantify 3-indoleacetic acid production and to measure the enzymatic activity of 1-aminocyclopropane-1-carboxylate (ACC) deaminase; proteome-level changes of P. putida UW4/pETP and P. putida UW4/pETP-unkG were profiled using two-dimensional difference in-gel electrophoresis (DIGE), followed by mass spectrometry identification of the altered proteins. After running DIGE, sixteen altered proteins were identified and their possible roles in the interactions between the bacterium and plants were discussed. Based on the preliminary results, we hypothesize that 1) UnkG may be detrimental to plant growth; 2) UnkG may negatively regulate a number of key cellular functions in a general way related to the energy balance of the bacterium.

This thesis identifies how the IT function can create agility in existing information systems. Agility is the capability to quickly sense and respond to environmental perturbations. This thesis contrasts the agility perspective from a widely used industry framework with research perspectives on agility in the IS literature. Beer’s Viable System Model is a useful meta-level theory to house agility elements from IS research literature and applies cybernetic principles to identify the capabilities required of the IT function. Indeed, a survey of 70 organizations confirms that the meta-level theory better correlates with reported agility measures than existing practice measures do on their own. / There were three stages to the research. First, was conceptually applying the Viable System Model to the concept of agility from IS research literature. The cybernetic model proposed an explanative theory for agility in information systems and prescribed capabilities for the IT function. / The second research stage was a qualitative study with an IT consultancy. Managers and consultants participated in applicability checking the theoretical development to the agility topic. The level of analysis was the client base of an IT consultancy, which consists of approximately 250 Australian organizations. A research deliverable was a joint white paper between the University of Melbourne and the IT consultancy. / The final stage was two quantitative surveys for theory testing. The first survey mailed a Likert-type questionnaire to business and IT managers amongst the IT consultancy’s clients. The second survey invited international members of professional interest groups to complete a web-based questionnaire. The responses from the surveys were analyzed using partial-least-squares modeling and linear regression. The data analysis correlated process maturity of the IT function and the likelihood of agility in existing information systems. The thesis claims to generalize the survey findings to other large organizations in OECD countries. / The thesis offers an agility-capability model for the IT function, which extends IS research with a theory that explains and predicts agility in existing information systems. A further contribution is to improve IT industry ‘best practice’ frameworks by prescribing capabilities to develop.

AN ABSTRACT OF THE THESIS OF MEGAN K. CLEARY, for the Master of Arts degree in ANTHROPOLOGY, presented on MARCH 28th at 8am, at Southern Illinois University Carbondale TITLE: SEX ESTIMATION FROM THE CLAVICLE: A DISCRIMINANT FUNCTION ANALYSIS MAJOR PROFESSOR: Dr. Gretchen R. Dabbs The development of methods for sex estimation using postcranial remains other than the os coxa is imperative for physical anthropology to improve the reliability of biological profile estimates in cases of incomplete and/or fragmentary skeletal remains. As the last skeletal element to complete fusion, the clavicle has the longest period of time to develop sexually dimorphic features, making it an ideal skeletal element for use in sex estimation. Sexual dimorphism in the clavicle was assessed using 18 measurements of the left clavicle of 265 (129 females; 136 males) individuals from the Hamann-Todd Collection. Independent samples t-tests with Bonferroni correction show males and females differ at a statistically significant level for all 18 variables with a significance level of 0.0028. Discriminate function analyses using the stepwise method (0.05 to enter, 0.10 to exit) produced a four variable model with cross-validated accuracy of 89.8%. A holdout sample from the Hamann-Todd Collection (n=30) similar in demographic character to the calibration sample was tested using the four variable model. The accuracy of the four variable model on the holdout sample was 90.0%. Additionally, four single variable models developed to accommodate fragmentary remains also have high predictive power (75.1-82.3% cross-validated calibration sample; 60.0-86.7% hold-out sample).
