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
Increasing public criticism of traditional teacher evaluation systems based largely on classroom observations has spurred an unprecedented shift in the debate surrounding educational accountability policies, specifically about the purposes for and measures used to evaluate teachers. In response to growing public demand and associated federal mandates, states have been prompted to design and implement teacher evaluation systems that use increasingly available, statistically complex models (i.e., value-added) intended to isolate and measure the effects of individual teachers on student academic growth over time. The purpose of this study was to examine the perceptions of school administrators and teachers within one of the largest school districts in the state of Arizona with regards to the design and implementation of a federally-supported, state policy-directed teacher evaluation system based on professional practice and value-added measures. While much research has been conducted on teacher evaluation, few studies have examined teacher evaluation systems in context to better understand the standards of effectiveness used by school administrators and teachers to measure system effectiveness. The perceptions of school administrators and teachers, considering their lived experiences as the subjects of the nation's new and improved teacher evaluation systems in context, must be better understood if state and federal policymakers are to also better recognize and understand the consequences (intended and unintended) associated with the design and implementation of these systems in practice.

Description
Although open access publishing has been available since 1998, we know little regarding scholars' perceptions and practices toward publishing in open access outlets, especially in the social science community. Open access publishing has been slow to penetrate the field of education, yet the potential impact of open access could make this publishing method an important innovation for understanding how to support the publishing needs of education scholars. To discover these perceptions and practices that education scholars have toward open access publishing, a 51-item web-based survey was provided to scholars with known investment in open access publishing. Participants had either (1) a publication in one of 34 United States education-based open access journals or (2) a manuscript submitted for peer review in one of those 34 journals. The survey contained subscales focusing on contemporary open access themes--issues identified through a comprehensive analysis of the major outlets for scholarly news in education. Through open and axial coding, several themes were extracted. They included rights and ease of access, ease of publishing, costs, support from colleagues and administrators, and perceived quality of open access outlets. The survey showed moderate to high reliability using Cronbach's alpha. Correlation and MANOVA testing showed significant results in scholars' teaching status and peer review status of manuscripts. Additional findings indicated that non-tenured education scholars responded more strongly than tenured scholars to issues related to rights and ease of access, promotion, and quality. Scholars with manuscripts currently in peer review felt strongly about themes of rights and ease of access, cost, and promotion. The results imply the following: (1) If scholars want their research read by a wider audience, they should publish in open access journals. (2) Pro-open access policies and procedures could gain more support by ensuring open access is promoted to non-tenured scholars seeking to publish. (3) More research, forums, discussions, and education about open access need to occur in greater abundance to continue to ameliorate scholars' views about the benefits of open access publishing. (4) Institutions and departments can offer their unconditional support for open access publishing as a method of meeting promotion/tenure requirements.

Description
In this case study, the formal feedback process of the PCC was researched to determine if the process causes a potential threat state within PCC representatives, and, if so, identify aspects of the process that are potential causes of the threat state. Researched was complete via survey, and data was analyzed using open coding and various quantitative methods. Based on the data obtained in the survey, a threat state was determined to exist due to the feedback process, and two potential causes were identified. A recommendation report was built from the data, and two recommendations were presented. The first recommendation was to adjust to process of how feedback is sent to a PCC rep, and the second was around how often that feedback is delivered. Also included in the recommendation report was discussion around limitations to the research and how those are potential options for future research.

Description
Since the early 2000s the Rubik’s Cube has seen growing usage at speedsolving competitions and as an effective tool to teach Science, Technology, Engineering, Mathematics (STEM) topics at hundreds of schools and universities across the world. Recently, cube manufacturers have begun embedding sensors to enable digital face tracking. The live feedback from these so called “smartcubes” enables a new wave of immersive solution tutorials and interactive educational games using the cube as a controller. Existing smartcube software has several limitations. Manufacturers’ applications support only a narrow set of puzzle form factors and application platforms, fragmenting the ecosystem. Most apps require an active internet connection for key features, limiting where users can practice with a smartcube. Finally, existing applications focus on a single 3x3x3connection, losing opportunities afforded by new form factors. This research demonstrates an open-source smartcube application which mitigates these limitations. Particular attention is given to creating an Application Programming Interface (API) for smartcube communication and building representative solve analysis tools. These innovations have included successful negotiations to re-license existing open-source Rubik’sCube software projects to support deployment on multiple platforms, particularly iOS. The resulting application supports smartcubes from three manufacturers, runs on two platforms (Android and iOS), functions entirely offline after an initial download of remote assets, demonstrates concurrent connections with up to six smartcubes, and supports all current and anticipated smartcube form factors. These foundational elements can accelerate future efforts to build smartcube applications, including automated performance feedback systems and personalized gamification of learning experiences. Such advances will hopefully enhance the Rubik’s Cube’s value both as a competitive toy and as a pedagogical tool in educational institutions worldwide.
