Bistability in Pseudomonas aeruginosa

The opportunistic pathogen P. aeruginosa is a leading cause of hospital-accquired infections, and is also the primary cause of morbidity and mortality in patients with cystic fibrosis (CF). In this thesis, I describe the identification and characterization of a novel LysR-type transcription regulator (LTTR) of P. aeruginosa named BexR. I show that BexR exhibits reversible ON/OFF bistable expression, which leads to the bistable expression of several genes including one encoding a virulence factor. I present results suggesting that this bistable expression depends on positive feedback of BexR. This work illuminates the simplicity with which a transcription regulatory network can exhibit a complex behavior and generate phenotypic diversity in a clonal population

Factors Influencing Consumer Choices in Graduate Nursing Education at Andrews University

Problem. Universities and colleges are increasingly interested in marketing strategies in order to improve enrollment. Nursing programs have likewise become more conscious of the need to be more market-oriented. Knowing the factors that influence consumer choices in higher education can enhance marketing strategies. The purpose of this qualitative study was to identify the factors related to marketing nursing graduate education that affect consumer choices in a particular program. Of special interest was the nursing student population in the Andrews University Graduate Nursing Program. Method. From the literature and from focus groups of a sample of the student population, data were obtained. The researcher conducted all focus group data gathering. The interview schedule was sent to three of the outreach sites for completion as a paper-and-pencil test as suggested in the literature for the quantitative value that is unobtainable by strictly qualitative analysis. The sample was voluntarily self-selected for all groups. Out of the 110 master\u27s students, 66 were actually involved in data collection for this study. Results. The study indicated that out of the marketing factors of product, place, price, and promotion, product and place are the most important. Accessibility, scheduling convenience, quality of the program, and quality of the faculty, the image, the Christian focus, and the emphasis on research were the most frequently reported factors that influence student choices in Andrews University master\u27s of nursing program. Conclusions. Knowledge provided by this research indicates that certain factors are identifiable that influence registered nurses in a choice of a particular program for graduate study. The analysis of the data obtained is applicable in developing a strategic marketing plan for the Department of Nursing at Andrews University. If the 10 highest-ranking factors consistently occur in repeated research, market planning for the master\u27s students in nursing can be executed more profitably in every program. The pragmatic value of this study is that the information can be applied immediately in the formulation of a strategic marketing plan. The tentative SWOT analysis and the marketing plan can be enhanced and actually used within the current academic year

Null geodesics in conformal gravity

Abstract We present an analysis of the null geodesics of the static, spherically symmetric, vacuum solution to the equations of conformal (Weyl) gravity. We classify the full range of exotic spacetimes arising from the parameter space of the metric. The nature of various notable features of these spacetimes is investigated including light spheres, horizons and physical singularities.</jats:p

An Evaluation of Performance and Structural Change in Employment- U.S., Nebraska, and Omaha Area Economies, 1988 to 1995

A periodic comparative evaluation of employment and its composition is worthwhile since employment is one of the most basic determinants of the health of the economy and quality of life. Changes in employment over time reflect restructuring of an economy and, ultimately, have social impacts. Moreover, the underlying trends of employment give an indication of an economy\u27s future growth and wellbeing. A future article will evaluate personal income as a measure of economic performance. This article examines employment data developed by the U. S. Department of Commerce, Bureau of Economic Analysis (BEA) and compiled by the Bureau of Business Research (BBR). To provide a consistent and comparable analysis, the initial and terminal years of the study, 1988 and 1995, both represent periods of healthy economic growth. The data tables summarize the economies of the U. S. (Table I), Nebraska (Table 2) and the Omaha Area (Tables 3 and 4). The Omaha area includes the Nebraska counties of Douglas, Sarpy, and Washington in Table 3. Pottawattamie County, Iowa is added to the Omaha area in Table 4. Pottawattamie County is also presented separately in Table 5 to show its growth relative to the rest of the Omaha Area. Employment Changes Summary of Employment Changes in the Economies Conclusio

Influential Article Review - Unlimited Possibilities for Business and Society With the Internet

This paper examines business opportunities through the internet. We present insights from a highly influential paper. Here are the highlights from this paper: The World Wide Web created a connection from computers to networks. The next evolution that followed connected people to the Internet and to other people. The Internet of Things (IoT) is emerging as the third wave in the development of the Internet. IoT interconnects devices, people, environments, virtual objects, and machines. IoT is expected to revolutionize and change the way all businesses, governments, and consumers interact with the physical world. In the exploding world of IoT, there is much to learn and an overwhelming amount of research to be done. The objective of this paper is to go beyond the hype and explore basic issues related to IoT technology, including its promises as well as its pitfalls. This study discusses potential strategic benefits of this technology as well as its risks and limitations. It highlights its evolving technologies and trends and their impact on the world of tomorrow. Also, it reviews IoT’s potential economic impact and explores many factors that may contribute to its successful adoption and deployment. Finally, this study explores IoT’s potential application in various industries. For our overseas readers, we then present the insights from this paper in Spanish, French, Portuguese, and German
