Can airline Yield Management strategies be used to generate additional revenue from spare capacity in telecom networks? Pundits believe " yes " , based on several analogies between the industries such as, for instance, perishable inventory and negligible marginal cost of usage. However, no one has yet described how, one of the chief difficulties being the(More)
The formulation of shelf-stable intermediate-moisture products is a critical food safety issue. Therefore, knowing the precise boundary for the growth-no-growth interface of Staphylococcus aureus is necessary for food safety risk assessment. This study was designed to examine the effects of various humectants and to produce growth boundary models as tools(More)
The interaction among demographic variables and motivation orientation were compared in students interested in completing online and traditional degree programs. Two hundred and sixty-five students enrolled at an open-enrollment state institution completed an online survey examining student interest in online degree programs. Results demonstrated similar(More)
This study utilized structural equation modeling to examine the relationship between alcohol use and academic motivation controlling for potentially mediating variables of deviant behavior, depressive cognitions, family communication, and peer relations. The study also examined the manner in which these relationships were moderated by gender. Results(More)
The International Commission on Microbiological Specifications for Foods (ICMSF) has recently proposed a scheme for the management of microbial hazards for foods that involves the concept of food safety objectives (FSOs). FSOs are intended to specify the maximum levels of hazardous agents required to meet a given public health goal. This scheme offers(More)
Students enrolled in a hybrid course reported their satisfaction with course design and delivery and their perceived academic performance. Students' perceptions of both satisfaction and performance were predicted using the benchmarks created for evaluating distance education (Chickering & Gamson, 1987). Specifically, students' perceptions of performance and(More)
Ceftazidime-avibactam and ceftolozane-tazobactam are new antimicrobials with activity against multidrug-resistant Pseudomonas aeruginosa. We present the first case of persistent P. aeruginosa bacteremia with in vitro resistance to these novel antimicrobials. A 68-year-old man with newly diagnosed follicular lymphoma was admitted to the medical intensive(More)
As existing technologies are refined and novel microbial inactivation technologies are developed, there is a growing need for a metric that can be used to judge equivalent levels of hazard control stringency to ensure food safety of commercially sterile foods. A food safety objective (FSO) is an output-oriented metric that designates the maximum level of a(More)

Drivers continuously evaluate the surrounding traffic and the roadway environment, and make decisions about lanes and travel speed. The objective of this thesis is to develop a lane changing model that can be used in microscopic traffic simulation models to capture drivers' lane changing behavior. Lane change is modeled as a sequence of four steps: decision(More)
AIM To determine if cell death from osmotic stress is because of lack of sufficient energy to maintain cell metabolism. Additionally, the solute-specific effect of five humectants on bacterial osmoregulation and cell survival was examined. METHODS AND RESULTS Staphylococcus aureus was placed into 84% relative humidity (RH) broth (five humectants used(More)
