Description
Mobile applications (Apps) markets with App stores have introduced a new approach to define and sell software applications with access to a large body of heterogeneous consumer population. Several distinctive features of mobile App store markets including – (a) highly heterogeneous consumer preferences and values, (b) high consumer cognitive burden of searching a large selection of similar Apps, and (c) continuously updateable product features and price – present a unique opportunity for IS researchers to investigate theoretically motivated research questions in this area. The aim of this dissertation research is to investigate the key determinants of mobile Apps success in App store markets. The dissertation is organized into three distinct and related studies. First, using the key tenets of product portfolio management theory and theory of economies of scope, this study empirically investigates how sellers’ App portfolio strategies are associated with sales performance over time. Second, the sale performance impacts of App product cues, generated from App product descriptions and offered from market formats, are examined using the theories of market signaling and cue utilization. Third, the role of App updates in stimulating consumer demands in the presence of strong ranking effects is appraised. The findings of this dissertation work highlight the impacts of sellers’ App assortment, strategic product description formulation, and long-term App management with price/feature updates on success in App market. The dissertation studies make key contributions to the IS literature by highlighting three key managerially and theoretically important findings related to mobile Apps: (1) diversification across selling categories is a key driver of high survival probability in the top charts, (2) product cues strategically presented in the descriptions have complementary relationships with market cues in influencing App sales, and (3) continuous quality improvements have long-term effects on App success in the presence of strong ranking effects.

Description
Unmanned aerial vehicles have received increased attention in the last decade due to their versatility, as well as the availability of inexpensive sensors (e.g. GPS, IMU) for their navigation and control. Multirotor vehicles, specifically quadrotors, have formed a fast growing field in robotics, with the range of applications spanning from surveil- lance and reconnaissance to agriculture and large area mapping. Although in most applications single quadrotors are used, there is an increasing interest in architectures controlling multiple quadrotors executing a collaborative task. This thesis introduces a new concept of control involving more than one quadrotors, according to which two quadrotors can be physically coupled in mid-flight. This concept equips the quadro- tors with new capabilities, e.g. increased payload or pursuit and capturing of other quadrotors. A comprehensive simulation of the approach is built to simulate coupled quadrotors. The dynamics and modeling of the coupled system is presented together with a discussion regarding the coupling mechanism, impact modeling and additional considerations that have been investigated. Simulation results are presented for cases of static coupling as well as enemy quadrotor pursuit and capture, together with an analysis of control methodology and gain tuning. Practical implementations are introduced as results show the feasibility of this design.

Description
The purpose of this paper is to present a case study on the application of the Lean Six Sigma (LSS) quality improvement methodology and tools to study the analysis and improvement of facilities management (FM) services at a healthcare organization. Research literature was reviewed concerning whether or not LSS has been applied in healthcare-based FM, but no such studies have been published. This paper aims to address the lack of an applicable methodology for LSS intervention within the context of healthcare-based FM. The Define, Measure, Analyze, Improve, and Control (DMAIC) framework was followed to test the hypothesis that LSS can improve the service provided by an FM department responsible for the maintenance and repair of furniture and finishes at a large healthcare organization in the southwest United States of America. Quality improvement curricula and resources offered by the case study organization equipped the FM department to apply LSS over the course of a five-month period. Qualitative data were gathered from pre- and post-intervention surveys while quantitative data were gathered with the Organization’s computerized maintenance management system (CMMS) software. Overall, LSS application proved to be useful for the intended purpose. The author proposes that application of LSS by other FM departments to improve their services could also be successful, which is noteworthy and deserving of continued research.

Description
Background: Health information technology (HIT) refers to the electronic health care systems organizations used to store, share and analyze healthcare information. A central component of the HIT infrastructure is an electronic health record (EMR) and although HIT has been shown to increase enthusiasm for patient care, decrease healthcare costs and improve patient outcomes overall utilization in the United States (US) remains low.
Methods: At an urban primary care pediatric office located in the southwestern US, an educational quality improvement project for healthcare practice providers and front office staff was conducted to increase the utilization of the existing EMR-linked patient portal. The healthcare providers were asked to complete a pre- and post- survey evaluation of their knowledge and usage of the patient portal. Provider and patient portal data usage was collected over a five-month period, September 2019 to January 2020.
Results: Data was analyzed using the Intellectus Statistics softwareTM. Significant results were found at the conclusion of the project in the number of active patient portal users, web-enabled, portal logins, labs published/viewed, messages sent, appointment reminders and Santovia utilization. At the end of the project no significance was found with messages received by the healthcare providers or staff through the patient portal. Survey results found significant differences between pre- and post- portal usage. No significance was found on providers’ knowledge on how to web-enable patients. Providers’ also demonstrated no significant change in their perceptions of the benefit in utilizing the portal in patient care after the educational intervention. Survey results allowed for additional analysis of commonly utilized portal functionalities, disease or health topics utilized in Santovia, and suggestions on how to make the use of the patient portal easier for providers.
Implications for Health Care Providers: This quality improvement project found that implementation an EMR-linked patient portal requires a comprehensive practice approach with structured education sessions. Including all employees can improve patient portal utilization. This educational project resulted in significant increases in most portal functionalities within 5 months. Further practice change evaluations are needed to evaluate how to improve patient portal utilization with a larger group of participants in a variety of outpatient settings.

Description
Purpose: To educate clinic staff on interventions and education materials which are suitable for implementation in a pediatric primary care setting, and to improve delivery and documentation of appropriate asthma interventions and inhaler/spacer education.
Background: Asthma is a chronic illness that impacts 10.9% of the pediatric population in Arizona. Poor asthma understanding and management leads to high-utilization of emergency rooms and urgent care clinics, negatively impacting the healthcare economy. Poor asthma management also leads to decreased health outcomes and impacts on the child’s academic functioning, mental health, and overall quality of life. Current evidence supports use of written asthma action plans (WAAP) and inhaler/spacer instruction to improve asthma management.
Methods: The intervention was an evidence-based educational session provided to the staff of a military, pediatric primary care clinic in southwest Arizona regarding the use of WAAP, the Asthma Control Test (ACT) and integrated inhaler/spacer instruction. Chart reviews were conducted to evaluate the documentation of use of WAAP, ACT, and inhaler/spacer education.
Results: Charts were collected from pre-intervention (n = 33) and post-intervention (n = 18). Data analysis demonstrated a statistically significant higher use of WAAP (U = 0.008, p < 0.05, d = 0.83). Although there was not a statistically significant change in use of ACT tool, Cohen’s value (d = 0.48) suggested a moderate positive effect. A Pearson correlation coefficient was also calculated for the relationship between use of ACT tool and use of WAAP, demonstrating a moderate positive correlation (r (49) = .372, p < .01).
Conclusions: An evidence-based education session for pediatric staff members is a cost-effective and simple method of improving pediatric asthma management practices.

Description
Purpose: Improper management of asthma leads to poor patient outcomes and increases in both costs and resources. This study aims to increase provider adherence to asthma clinical practice guidelines.
Methods: A multifaceted intervention was utilized that included educational sessions for providers, adjustments to the electronic health record (EHR), access to toolkits, and workflow changes. Pediatric patients aged 5-18 years and diagnosed with asthma (N = 173) were evaluated using a pre-post design. Provider adherence to key components of clinical practice guidelines were assessed prior to implementation, and a three and six months post-implementation. Data was analyzed using descriptive statists and the Friedman’s ANOVA by rank.
Results: Provider education, EHR adjustments, provider toolkits, and changes to office workflow improved provider adherence to key aspects of asthma clinical practice guidelines. A significant difference was found between the pre and post implementation groups (p < .01).
Conclusion: Increased adherence to clinical practice guidelines leads to fewer complications and an overall improved quality of life. Continuing provider education is critical to sustained adherence.

Description
Background: There is growing evidence that persistent exposure to the adverse effects of stressful work conditions, abuse, and re-traumatization without proper intervention leads to compassion fatigue (CF) and reduced compassion satisfaction (CS). Without appropriate intervention, the outcome of CF affects the patient, staff, and the organization. Despite proposed self-care measures, mental health (MH) workers continue to struggle with CF and lack the resources to combat the issue.
Objectives: Ongoing awareness on the implications of trauma and its impact on one's behavior, supports the use of Trauma-informed care (TIC) skills in creating a conducive work environment. This quality improvement project examines the efficacy of TIC education as an intervention for CF pre/post-one-hour education session among MH workers.
Methods: MH nurses (n=8) from diverse backgrounds in a Phoenix inpatient psychiatric hospital gave consent for the study. Participation was sought via flyers and entailed attending the one-hour education session, filling out a demographic, and pre/post-professional quality of life (ProQol) surveys. The ProQol standardized tool measures CF, CS, and burnout with reliability >0.70. Expected outcomes include a reduction in CF and an improvement in CS. Data analysis using intellectus software involved descriptive analysis and paired t-tests to compare outcomes.
Results: Pre/post data analysis was statistically significant, P = 0.003, which shows a reduction in CF and an improvement in CS.
Conclusion: TIC as an intervention for CF looks promising. MH nurses can manage their stress symptoms and that of their patients using TIC skills.

Description
Objective
A needs assessment identified a nursing knowledge gap of chemotherapy-induced neurotoxicity (CIN) symptoms as a significant factor in delayed recognition of patients' neurologic decline. The quality improvement (QI) project aimed to increase nursing comfort levels and knowledge related to screening for CIN in hospitalized pediatric hematology, oncology, and bone marrow transplant (Heme/Onc/BMT) patients.
Methods
Nursing CIN education and pre- and post-education assessment questions were created using best practice parameters to screen and monitor CIN in Heme/Onc/BMT pediatric patients. Pre- and post-surveys included a valid Likert-type scale to assess comfort levels using neurotoxicity screening tools (NST) followed by knowledge-based formative assessments. ASU IRB and hospital QI board standards were maintained.
Results
Heme/Onc/BMT nurses (n=37) participated. The most frequent pre-education comfort level was three or somewhat comfortable (n=13). Most frequent post-education comfort level is four or very comfortable (n=21). The two-tailed Wilcoxon signed rank test for pre- and post-education comfort levels was significant based on an alpha value of .05 and p < .001.
Conclusion
Nursing comfort and knowledge of screening for CIN increased. Early recognition of CIN will improve outcomes for high-risk hospitalized Heme/Onc/BMT pediatric patients.

Description
Background: An evidence-based project was performed to train and increase skills among healthcare providers to perform advance care planning. Training decreases barriers and improves attitudes and confidence to perform advance care planning. Advance care planning can include the Physician Order for Life-sustaining Treatment, an out-of-hospital order that directs emergency medical services of a patient’s wishes. Internal evidence found that many providers are unfamiliar with the Physician Order for Life-Sustaining Treatment form. The Theory of Planned Behavior was used to guide the project.
Objectives: To improve advanced care planning processes in a healthcare organization.
Design: A quality improvement project was performed at a medical center with outpatient provider groups. Virtual training was provided by the Arizona Hospital and Healthcare Association on the Physician Order for Life-Sustaining Treatment. Participants completed a three-part survey to measure skills for advance care planning after a training event.
Setting/Subjects: Five (n=5) American palliative and primary care providers at a medical center.
Measurements: The East Midlands Evaluation Toolkit is a validated survey tool that measures confidence and competence in advance care planning after training.
Results: Descriptive statistics, Friedman’s test, and the Kruskal-Wallis test were used for data analysis. Results provided evidence to the healthcare facility that there is a significant need to train their healthcare professionals on advance care planning.
Conclusions: Recommendations are made to focus research on larger studies looking at the types of advance care planning, and differences in disciplines and specialties.

Description
Background: Advance Care Planning (ACP) conversations are discussions between patients, providers, and loved ones addressing key care decisions in the event of incapacity. Nearly twothirds of US adults have not completed an Advance Directive (AD), yet ACP conversations rarely occur in practice. The objective of this quality improvement project was to implement workflow changes with a reminder system to facilitate ACP conversations during Medicare Wellness Visits (MWV).
Method: Social Cognitive Theory describes the complex relationship between variables that can influence an individual’s decision to address ACP. Providers in a primary care office in the Southwestern United States participated in an ACP education session and confidence survey. Patients presenting for the MWV were screened for ACP, and visual reminders were attached outside the exam room for provider review. Aggregate data were used to evaluate provider surveys. Descriptive statistics were used to evaluate patient characteristics and the Chi-square Test of Independence, and Fisher’s test was used to compare the pre-and post-intervention advance directive documentation.
Results: Qualitative feedback from the survey indicates reminders and easily accessible resources may help facilitate ACP conversations. Of the 251 MWVs, 21 (8%) had an AD documented, significantly less than the nationally reported rate of 37.7% (p < 0.05, z = -2.39).
Conclusions: Healthcare providers face multiple barriers preventing or delaying ACP conversations in practice. System-level changes and provider education can improve the rate of ACP conversations and impact patients’ care at the end of life.
