A Two-Echelon Location-Inventory Model For A Multi-Product Donation-Demand Driven Industry, Milad Khajehnezhad
Theses and Dissertations
This study involves a joint bi-echelon location inventory model for a donation-demand driven industry in which Distribution Centers (DC) and retailers (R) exist. In this model, we confine the variables of interest to include; coverage radius, service level, and multiple products. Each retailer has two classes of product flowing to and from its assigned DC i.e. surpluses and deliveries. The proposed model determines the number of DCs, DC locations, and assignments of retailers to those DCs so that the total annual cost including: facility location costs, transportation costs, and inventory costs are minimized. Due to the complexity of problem, the …

Consumer Adoption Of Health Information Systems, Sankara Subramanian Srinivasan
Graduate Theses and Dissertations
At nearly 18 percent of the country's GDP, the U.S. healthcare industry continues to wrestle with growing cost and a quality of care that does not match the increased spending. The dominant focus to date has been on promoting Health IT (HIT) system implementation and digitizing health records at the provider's end, with scant attention to the role of the patient in the healthcare process. The source of inefficiency in the healthcare system is not only on account of shortcomings at the provider's end but also due to non-compliance (such as failing to adhere to medication advice and follow-up visits) …

Recreation Displacement Of Bass Fishermen From Central Coast Lakes, Erin Gray
Recreation, Parks, and Tourism Administration
The purpose of this study was to assess the impacts of aquatic invasive species preventative measures on recreation displacement of bass fishermen from Central Coast lakes. A self-administered questionnaire was distributed to participants at a local bass fishing tournament. Thirty-six respondents completed the questionnaire. The results indicated that boat inspection procedures do not necessarily cause bass fishermen to displace. This study found that fishermen are likely to avoid recreating at a Central Coast lake in fishing practice conditions rather than in tournament conditions, and are likely to avoid tournaments at their least favorite lake if boat inspection procedures take too …
Concept Graphs: Applications To Biomedical Text Categorization And Concept Extraction, Said Bleik
Concept Graphs: Applications To Biomedical Text Categorization And Concept Extraction, Said Bleik
Dissertations
As science advances, the underlying literature grows rapidly providing valuable knowledge mines for researchers and practitioners. The text content that makes up these knowledge collections is often unstructured and, thus, extracting relevant or novel information could be nontrivial and costly. In addition, human knowledge and expertise are being transformed into structured digital information in the form of vocabulary databases and ontologies. These knowledge bases hold substantial hierarchical and semantic relationships of common domain concepts. Consequently, automating learning tasks could be reinforced with those knowledge bases through constructing human-like representations of knowledge. This allows developing algorithms that simulate the human reasoning …

Communication Artifacts And Interaction Evaluation For Requirements Engineering, Miloslava Plachkinova
Communication Artifacts And Interaction Evaluation For Requirements Engineering, Miloslava Plachkinova
UNLV Theses, Dissertations, Professional Papers, and Capstones
This paper aims to answer an important question regarding the development of new information systems (IS): "What is the predominant factor for the selection of communication artifacts for requirements engineering (RE)?". Many researchers have focused on the RE and communication as separate disciplines, but little or no research addressed the RE communication issues. These problems are important because they often lead to misunderstanding and misinterpretation of the gathered requirements. We develop expectations about the RE communication process based on prior literature from both disciplines and we test them through several case studies. Our methodology consists of analysis of six case …

The Informavore Shopper: Analysis Of Information Foraging, System Design, And Purchasing Behavior In Online Retail Stores, Jeff Min Teck Hong
Dissertations and Theses Collection (Open Access)
Global online retail sales are on the rise and are predicted to experience a double digit growth annually over the next three years. Given little marginal cost involved in adding new products and brands to their catalogues, online retailers tend to increase product and brand offerings to increase sales by selling products that could not have been sold due to space constraints in physical stores. Frank Urbanowski, Director of MIT Press, attributed the 12% increase in sales of backlist titles directly to increased accessibility to these titles through the Internet. For consumers, the ability to buy products that they would …
