Relationships Between Healthcare Technology Experience, Acceptance, Attitudes, Self-Efficacy And Readiness In Pre-Licensure Nursing Students, Emily Lynne Boyce

UNLV Theses, Dissertations, Professional Papers, and Capstones

Introduction: Technology is embedded in many aspects of healthcare. This is especially true in nursing, where technology is used daily in charting, medication administration, clinical decision-making, healthcare team communication, and information resource utilization. In nursing programs, students are exposed to healthcare technologies and expected to use them once entering the workforce. Healthcare technologies such as electronic health records (EHR), barcode medication administration, medication dispensing machines, and mobile technologies are critical to adopt to leverage their efficiencies and safety mechanisms to provide the best patient care. Despite evidence indicating the benefits of using healthcare technologies, new graduate nurses enter the workforce …

Motivation And Online Information Literacy Instruction: A Self-Determination Theory Approach, Francesca Marineo

UNLV Theses, Dissertations, Professional Papers, and Capstones

Information literacy skills, including critical thinking and problem-solving skills, are imperative for academic, personal, and professional success. Unfortunately, many students graduate only to be more daunted than ever by the vast amount of information available to them and increasingly rely on convenience over quality in their information-seeking behaviors. This study hoped to address this by increasing students’ motivation for engaging in an online information literacy module. Using self-determination theory (SDT) from the field of motivation, motivationally-supportive modules were designed to support students’ feelings of autonomy and competence and ultimately grades on their final research assignment. Experimental conditions included providing relevance, …

Maintaining Nurses' Currency In Informatics, Jennifer Alaine Strawn

UNLV Theses, Dissertations, Professional Papers, and Capstones

Technology has changed how registered nurses (RNs) provide care at the bedside. As more technologies are utilized to improve quality of care, safety of care, maximize efficiencies, and decrease costs of care, one must question how well the information technologies (IT) are fully integrated and utilized by the front-line bedside nurse in his or her practice. Despite the pervasiveness of IT in healthcare, there is a paucity of literature on how Chief Nursing Officers (CNOs) assure the ongoing education and training for nurses to maintain IT competencies in the practice environment.

From this author’s lived experience as a CNO, it …

Understanding Transitions Of Trust Across Different Business Contexts: An Exploratory Sequential Mixed Methods Study, Sungsik Yoon

UNLV Theses, Dissertations, Professional Papers, and Capstones

Airbnb’s influence has been growing rapidly in the last few years, and hotel operators are beginning to recognize the competitive threat it poses. However, consumers may perceive Airbnb differently than hoteliers. Thus, the current study attempts to explore hotel customers’ perceptions of the sharing economy business (Airbnb). It is important to pay attention to the different business settings of the channels that currently exist in the lodging industry. Moreover, investigating the relationship between trust and perceived risk in this new channel (i.e., Airbnb) is crucial due to the inherent risk of transactions on Airbnb, especially when compared with traditional Business-to-customer. …

Teachers + School Librarians = Student Achievement: When Will We Believe It?, Gaetana D'Agata

UNLV Theses, Dissertations, Professional Papers, and Capstones

School librarians, teachers, and administrators have understood that student achievement can be enhanced when teachers and librarians collaborate. Most of the scholarly literature concerning teacher-school librarian collaboration has been written by school librarians rather than teachers and administrators. Consequently, the purpose of this study was to describe the concept of teacher-librarian collaboration from the perspectives of school librarians. Content analysis of 37 responses to a school librarians’ online discussion board revealed the barriers to and some of the supports for collaboration.

Persuasion Of Online Crowdfunding Videos, Matthew Roe

UNLV Theses, Dissertations, Professional Papers, and Capstones

Crowdfunding is a relatively new and exciting way to get investments for a business startup or other project. We use the elaboration likelihood model (ELM) to explore how individuals are persuaded by the project videos on a crowdfunding platform called Kickstarter. ELM is a psychological model used to understand how people are persuaded. Our results support most of our hypotheses and showed that the need for cognition, which reflects the personal tendency towards the central route of ELM, does increase an individual’s intent to back a project. We also discovered that intrinsic motivations and product quality have a stronger effect …

A Survey On Potential Privacy Leaks Of Gps Information In Android Applications, Srinivas Kalyan Yellanki

UNLV Theses, Dissertations, Professional Papers, and Capstones

Android-based smart phones are extremely common today. However, it is believed that nearly half of the Android devices are vulnerable to an attack that alters the functionality of an app with malicious software. The malware can collect users’ sensitive data from the phone. In particular, there are hundreds of location-based applications available nowadays in the Google Play store or other app stores. The very famous services called “Location Based Services” are used by many apps on mobile phones to track the geographical coordinates of the device. Such location information can be leaked to an attacker via malware.

Using The Web 1t 5-Gram Database For Attribute Selection In Formal Concept Analysis To Correct Overstemmed Clusters, Guymon Hall

UNLV Theses, Dissertations, Professional Papers, and Capstones

Information retrieval is the process of finding information from an unstructured collection of data. The process of information retrieval involves building an index, commonly called an inverted file. As part of the inverted file, information retrieval algorithms often stem words to a common root. Stemming involves reducing a document term to its root. There are many ways to stem a word: affix removal and successor variety are two common categories of stemmers. The Porter Stemming Algorithm is a suffix removal stemmer that operates as a rule-based process on English words. We can think of stemming as a way to cluster …

Fortifying The Pipeline: An Exploratory Study Of High School Factors Impacting The Information Literacy Of First-Year College Students, Jennifer L. Fabbi

UNLV Theses, Dissertations, Professional Papers, and Capstones

Information literacy—the ability "to recognize when information is needed and have the ability to locate, evaluate, and use effectively the needed information” (American Library Association [ALA], 1989, para. 3)—has been widely and increasingly cited as an essential competency for college success, for the workplace, and for life (Bruce, 1997; Eisenberg, 2008; Fitzgerald, 2004; Johnston & Webber, 2003; National Leadership Council for Liberal Education and America’s Promise, 2007; Obama, 2009; Rader, 2002). Information literacy best practice and standards state that students optimally develop this skill set through immersion in the research process—often and over time—and this proposition is also supported in …

Cloud Storage And Online Bin Packing, Swathi Venigella

UNLV Theses, Dissertations, Professional Papers, and Capstones

Cloud storage is the service provided by some corporations (such as Mozy and Carbonite) to store and backup computer files. We study the problem of allocating memory of servers in a data center based on online requests for storage. Over-the-net data backup has become increasingly easy and cheap due to cloud storage. Given an online sequence of storage requests and a cost associated with serving the request by allocating space on a certain server one seeks to select the minimum number of servers as to minimize total cost. We use two different algorithms and propose a third algorithm; we show …

A Comparative Study On Text Categorization, Aditya Chainulu Karamcheti

UNLV Theses, Dissertations, Professional Papers, and Capstones

Automated text categorization is a supervised learning task, defined as assigning category labels to new documents based on likelihood suggested by a training set of labeled documents. Two examples of methodology for text categorizations are Naive Bayes and K-Nearest Neighbor.

In this thesis, we implement two categorization engines based on Naive Bayes and K-Nearest Neighbor methodology. We then compare the effectiveness of these two engines by calculating standard precision and recall for a collection of documents. We will further report on time efficiency of these two engines.

Public Libraries: Is Independence Better?, Gayle Hornaday

UNLV Theses, Dissertations, Professional Papers, and Capstones

Since the origin of public libraries in the United States during the nineteenth century, they have been primarily supported by public taxation, due to their intended purpose of benefiting all of society, and especially the economically disadvantaged. Public libraries are provided in much the same spirit as public education, to uphold the American value that knowledge and information should be equally available to all, without regard to individual ability to pay. The dilemma of how to pay for library services has involved considerable debate in the library community about the implementation of user fees to supplement revenue, as an alternative …
