Does Patent Strategy Shape The Long-Run Supply Of Public Knowledge? Evidence From Human Genetics, Kenneth G. Huang, Fiona Murray Dec 2009

Does Patent Strategy Shape The Long-Run Supply Of Public Knowledge? Evidence From Human Genetics, Kenneth G. Huang, Fiona Murray

Research Collection Lee Kong Chian School Of Business

Knowledge-based firms seeking competitive advantage often draw on the public knowledge stream (ideas embedded in public commons institutions) as the foundation for private knowledge (ideas firms protect through private intellectual property [IP] institutions). However, understanding of the converse relationship—the impact of private knowledge strategies on public knowledge production—is limited. We examine this question in human genetics, where policy makers debate expanding IP ownership over the human genome. Our difference-in-differences estimates show that gene patents decrease public genetic knowledge, with broader patent scope, private sector ownership, patent thickets, fragmented patent ownership, and a gene's commercial relevance exacerbating their effect.

A Career Stage Perspective To Employees’ Preferred Psychological Contract Inducements, Chin Heng (Liu Zhenxing) Low, Prashant Bordia Dec 2009

A Career Stage Perspective To Employees’ Preferred Psychological Contract Inducements, Chin Heng (Liu Zhenxing) Low, Prashant Bordia

Research Collection Lee Kong Chian School Of Business

The psychological contract describes employees’ beliefs regarding the reciprocal obligations between themselves and their employer. While research has examined the consequences of psychological contract fulfillment and breach, there is limited understanding of how employees’ preferences for psychological contract inducements may vary across different stages of their careers. Drawing on career stage theory, this paper develops a conceptual framework proposing that employees at different perceived career stages will prioritize different inducements from their employer. Using Super’s career stage model, the paper identifies stage-specific inducements that may be valued by employees at early, mid, and late career stages. The framework offers insights …

Tb Research At Ut-Houston – A Review Of Cord Factor: New Approaches To Drugs, Vaccines And The Pathogenesis Of Tuberculosis, Robert L Hunter, Lisa Armitige, Chinnaswamy Jagannath, Jeffrey K Actor

Faculty, Staff and Student Publications

Tuberculosis remains a major threat as drug resistance continues to increase. Pulmonary tuberculosis in adults is responsible for 80% of clinical cases and nearly 100% of transmission of infection. Unfortunately, since we have no animal models of adult type pulmonary tuberculosis, the most important type of disease remains largely out of reach of modern science and many fundamental questions remain unanswered. This paper reviews research dating back to the 1950's providing compelling evidence that cord factor (trehalose 6,6 dimycolate [TDM]) is essential for understanding tuberculosis. However, the original papers by Bloch and Noll were too far ahead of their time …

Richmond Public Schools: Post-Court Mandated School Desegregation (1986-2006), Joshua Cole

Theses and Dissertations

In 1970, cross-town busing was court mandated to enforce school desegregation in Richmond, Virginia. Unitary status was declared in Richmond when cross-town busing ended in 1986. Richmond Public Schools (RPS) no longer operated as a dual school system for blacks and whites after 1986. Class and racial segregation continued to exist in the City of Richmond. RPS remained predominately black and poor. Socio-economic conditions of the city continued to impact the school district. Controversies, mismanagement and low academic achievement stigmatized RPS until state and federal performance measures forced the district to improve. By 2006, RPS was still segregated; however, as …

Evaluation Of Industrial Promoted Agroforestry In Andhra Pradesh And Madhya Pradesh, India, Brian D. Mcdonald Dec 2009

Evaluation Of Industrial Promoted Agroforestry In Andhra Pradesh And Madhya Pradesh, India, Brian D. Mcdonald

Graduate Theses, Dissertations, and Problem Reports (ETD)

In many parts of the world, pulp and paper companies are becoming heavily dependent on private agroforestry schemes. With growing demand for wood fiber and limited commercial land to grow it on, the forest industry is continually turning to private farmers and individuals to contract timber. In order to alleviate this problem, many companies have turned to out-grower schemes to supply wood to the mills. Local farmers now have the opportunity to benefit from company extension and supplies, and in return, the company can guarantee its supply of raw materials.;A recent trend in agriculture is adding trees to farmers? traditional …

Interleukin (Il)-1 Regulates Ozone-Induced Nerve Growth Factor (Ngf) And Substance P (Sp) Release In Bronchoalveolar Lavage Fluid (Balf) In Mice, Joshua S. Barker Dec 2009

Interleukin (Il)-1 Regulates Ozone-Induced Nerve Growth Factor (Ngf) And Substance P (Sp) Release In Bronchoalveolar Lavage Fluid (Balf) In Mice, Joshua S. Barker

Graduate Theses, Dissertations, and Problem Reports (ETD)

Previous studies show that both IL-1 and NGF increase synthesis of SP in airway neurons after either direct application or ozone exposure. We hypothesize that NGF mediates ozone-induced IL-1 effects on SP, similar to the pathway described for sympathetic neurons in culture. The current study specifically focuses on the effect of ozone on IL-1, NGF, and SP levels in mice BALF and if these mediators can be linked in an inflammatory-neuronal cascade in vivo. The experiments demonstrate in vivo ozone exposure induces an increase of all three proteins in mouse BALF and that both ozone-induced increases in NGF and SP …

A Process Examination Of The Framing Effect In Younger And Older Adult Medical Decision Making, Erin L. Woodhead Dec 2009

A Process Examination Of The Framing Effect In Younger And Older Adult Medical Decision Making, Erin L. Woodhead

Graduate Theses, Dissertations, and Problem Reports (ETD)

Older and younger adults are susceptible to a decisional bias when faced with medical decisions, which results in different treatment decisions when presented with survival or mortality data. Although this bias, termed the framing effect, has been demonstrated in multiple studies, no published studies have attempted to determine the decisional process older and younger adults engage in when presented with different information frames. The current study used a think-aloud procedure to examine decisional process differences in younger and older adults who did and did not demonstrate a framing effect. All participants were presented with two data formats (interval and cumulative …

The Evaluation Of A Nutrition Education And Fitness Program With A Contest Component Among College Students Using The Re-Aim Framework, Michelle L. Bartlett Dec 2009

The Evaluation Of A Nutrition Education And Fitness Program With A Contest Component Among College Students Using The Re-Aim Framework, Michelle L. Bartlett

Graduate Theses, Dissertations, and Problem Reports (ETD)

Only recently have practitioners and researchers targeted the population of college students in studying interventions aimed at increasing health behaviors. There is evidence that a proportion of college students are making attempts on their own to remedy weight gain and poor physical fitness with little or no guidance, which is reflected in consistently rising obesity rates in this population. Thus, the need for organized and effective interventions is illustrated. The impact of an intervention can be determined through evaluation research. Although the RE-AIM model has not yet been used to evaluate single-site, university-sponsored, college-student weight-loss/fitness programs, it provided a useful …

Post-Transcriptional Regulation Of Rpos And Hema In Salmonella, Amy Madeline Jones Dec 2009

Post-Transcriptional Regulation Of Rpos And Hema In Salmonella, Amy Madeline Jones

Graduate Theses, Dissertations, and Problem Reports (ETD)

The first part of this thesis is dedicated to translational regulation of rpoS mRNA by the small noncoding RNAs (sRNAs), DsrA and RprA, in two closely related enteric bacteria, Escherichia coli, and Salmonella enterica serovar Typhimurium. The rpoS gene encodes a second vegetative sigma factor for RNA polymerase, which directs the cell's transcriptional response to general stress and entry into stationary phase. The rpoS gene is highly conserved among the gamma-branch of proteobacteria, and sRNAs are highly conserved in related species. In fact, sequence conservation is thought to have predictive value in sRNA discovery and functional conservation is largely assumed. …

Mechanism By Which Dietary Polyunsaturated Fat Regulates Lipogenic Gene Expression, Alison Bloom Kohan Dec 2009

Mechanism By Which Dietary Polyunsaturated Fat Regulates Lipogenic Gene Expression, Alison Bloom Kohan

Graduate Theses, Dissertations, and Problem Reports (ETD)

Primary hepatocytes treated with non-esterified polyunsaturated fatty acids have been used as a model for describing the inhibitory effects of dietary polyunsaturated fats on lipogenic gene expression. This model resembles starvation or uncontrolled diabetes but not dietary fat ingestion, which is delivered to liver via chylomicron remnants. Chylomicron remnants enriched with polyunsaturated fatty acids stimulate a unique pattern of intracellular signaling. These remnants enhance p38 mitogen activated protein kinase (MAPK) activity but do not inhibit insulin signaling or induce extracellular-signal related kinase (ERK) or AMP-activated protein kinase (AMPK) activation as do non-esterified polyunsaturated fatty acids. Polyunsaturated fatty acids-enriched remnants and …

Prevalence And Biological Control Of Salmonella Contamination In Rendering Plant Environments And The Finished Rendered Meals, Brandon Kinley Dec 2009

Prevalence And Biological Control Of Salmonella Contamination In Rendering Plant Environments And The Finished Rendered Meals, Brandon Kinley

All Dissertations

Although the rendering process serves as invaluable means for the disposal of inedible animal by-products, the finished products often harbor pathogenic and opportunistic microorganisms such as Salmonella and enterococci, respectively. The temperatures used during the rendering process far exceed the heat tolerance threshold of most bacterial species, so cross-contamination from the environment and/or from the incoming raw material is the proposed source of the contamination. Research has demonstrated that the raw material coming into the rendering facility is highly contaminated with pathogenic bacteria including Salmonella. While not in a rendering facility, studies have also demonstrated that bacteria such as Salmonella …

Characterization Of Escherichia Coli Related To Construction Site Sediment Basins, Calvin Sawyer Dec 2009

Characterization Of Escherichia Coli Related To Construction Site Sediment Basins, Calvin Sawyer

All Dissertations

Large construction sites can have significant temporary and permanent impacts on the physical landscape. Excess sediment is frequently deposited into nearby surface waters, altering benthic habitat, reducing water clarity and transporting other pollutants such as enteric bacteria. To capture eroded soil and attenuate storm discharge peaks, many permitted construction projects larger than 10 acres in South Carolina require the installation of a sediment basin. Sediment-laden runoff is routed to a newly excavated impoundment, where larger particles settle out of suspension. Thus an entirely new hydrologic feature designed to concentrate eroded sediment and water is introduced into the landscape.
Eight construction …
