Description
This study explores the impact of feedback and feedforward and personality on computer-mediated behavior change. The impact of the effects were studied using subjects who entered information relevant to their diet and exercise into an online tool. Subjects were divided into four experimental groups: those receiving only feedback, those receiving only feedforward, those receiving both, and those receiving none. Results were analyzed using regression analysis. Results indicate that both feedforward and feedback impact behavior change and that individuals with individuals ranking low in conscientiousness experienced behavior change equivalent to that of individuals with high conscientiousness in the presence of feedforward and/or feedback.

Forrest Research estimated that revenues derived from mobile devices will grow at an annual rate of 39% to reach $31 billion by 2016. With the tremendous market growth, mobile banking, mobile marketing, and mobile retailing have been recently introduced to satisfy customer needs. Academic and practical articles have widely discussed unique features of m-commerce. For instance, hardware constraints such as small screens have led to the discussion of tradeoff between usability and mobility. Needs for personalization and entertainment foster the development of new mobile data services. Given distinct features of mobile data services, existing empirical literature on m-commerce is mostly from the consumer side and focuses on consumer perceptions toward these features and their adoption intentions. From the supply side, limited data availability in early years explains the lack of firm-level studies on m-commerce. Prior studies have shown that unclear market demand is a major reason that hinders firms' adoption of m-commerce. Given the advances of smart phones, especially the introduction of the iPhone in 2007, firms recently have started to incorporate various mobile information systems in their business operations. The study uses mobile retailing as the context and empirically assesses firms' migration to this new sales venue with a unique cross-sectional dataset. Despite the distinct features of m-commerce, m-Retailing is essentially an extended arm of e-Retailing. Thus, a dependency perspective is used to explore the link between a firm's e-Retail characteristics and the migration to m-Retailing. Rooted in the innovation diffusion theory, the first stage of my study assesses the decision of adoption that indicates whether a firm moves to m-Retailing and the extent of adoption that shows a firm's commitment to m-Retailing in terms of system implementation choices. In this first stage, I take a dependency perspective to examine the impacts of e-Retail characteristics on m-Retailing adoption. The second stage of my study analyzes conditions that affect business value of the m-Retail channel. I examine the association between system implementation choices and m-Retail performance while analyzing the effects of e-Retail characteristics on value realization. The two-stage analysis provides an exploratory assessment of firm's migration from e-Retailing to m-Retailing.

Description
Knowledge Management Systems have been actively promoted for decades within organizations but have frequently failed to be used. Recently, deployments of enterprise social networking platforms used for knowledge management have become commonplace. These platforms help harness the knowledge of workers by serving as repositories of knowledge as well as directories of knowledge holders. As with prior systems, a key challenge faced by organizations is how to initiate and maintain a minimum level of knowledge contributions. Existing IS literature on the causes of knowledge contributions shows conflicting findings. This work suggests that human factors, social networking platform technology and community factors, and environments internal to organizations are each necessary for understanding the causes of knowledge contributions. This work presents three studies that: 1) develop a framework for the analysis of knowledge contributions via social networking platforms, 2) demonstrate the impacts of different incentives and managerial controls, and 3) extend our understanding of group-level influences within organizations. With a better understanding of what drives knowledge contributions in a social networking platform used in organizations, we are better prepared as researchers to engage in research that reduces inconsistencies in the knowledge management literature, as well as more able to assist practitioners in designing optimal conditions for knowledge sharing within organizations.

Description
Information technology (IT) outsourcing, including foreign or offshore outsourcing, has been steadily growing over the last two decades. This growth in IT outsourcing has led to the development of different hubs of services across nations, and has resulted in increased competition among service providers. Firms have been using IT outsourcing to not only leverage advanced technologies and services at lower costs, but also to maintain their competitive edge and grow. Furthermore, as prior studies have shown, there are systematic differences among industries in terms of the degree and impact of IT outsourcing. This dissertation uses a three-study approach to investigate issues related to IT outsourcing at the macro and micro levels, and provides different perspectives for understanding the issues associated with IT outsourcing at a firm and industry level. The first study evaluates the diffusion patterns of IT outsourcing across industries at aggregate level and within industries at a firm level. In addition, it analyzes the factors that influence the diffusion of IT outsourcing and tests models that help us understand the rate and patterns of diffusion at the industry level. This study establishes the presence of hierarchical contagion effects in the diffusion of IT outsourcing. The second study explores the role of location and proximity of industries to understand the diffusion patterns of IT outsourcing within clusters using the spatial analysis technique of space-time clustering. It establishes the presence of simultaneous space and time interactions at the global level in the diffusion of IT outsourcing. The third study examines the development of specialized hubs for IT outsourcing services in four developing economies: Brazil, Russia, India, and China (BRIC). In this study, I adopt a theory-building approach involving the identification of explanatory anomalies, and propose a new hybrid theory called- knowledge network theory. The proposed theory suggests that the growth and development of the IT and related services sector is a result of close interactions among adaptive institutions. It is also based on new knowledge that is created, and which flows through a country's national diaspora of expatriate entrepreneurs, technologists and business leaders. In addition, relevant economic history and regional geography factors are important. This view diverges from the traditional view, wherein effective institutions are considered to be the key determinants of long-term economic growth.

Description
Ample evidence exists to support the conclusion that enterprise search is failing its users. This failure is costing corporate America billions of dollars every year. Most enterprise search engines are built using web search engines as their foundations. These search engines are optimized for web use and are inadequate when used inside the firewall. Without the ability to use popularity-based measures for ranking documents returned to the searcher, these search engines must rely on full-text search technologies. The Information Science literature explains why full-text search, by itself, fails to adequately discriminate relevant from irrelevant documents. This failure in discrimination results in far too many documents being returned to the searcher, which causes enterprise searchers to abandon their searches in favor of re-creating the documents or information they seek. This dissertation describes and evaluates a potential solution to the problem of failed enterprise search derived from the Information Science literature: subject-aided search. In subject-aided search, full-text search is augmented with a search of subject metadata coded into each document based upon a hierarchically structured subject index. Using the Design Science methodology, this dissertation develops and evaluates three IT artifacts in the search for a solution to the wicked problem of enterprise search failure.

Description
This thesis will examine market research relating to consumer food trends and the business environment of Austin, Texas in order to evaluate the initial feasibility of establishing a small hydroponic produce farm. A main concern of this report is to provide a general overview of hydroponics and its potential advantages over traditional farming methods as a technique for producing food products for consumers in a local setting. To explore the potential of establishing such a venture, this report will also include a partial business plan focusing on the marketing strategy of initiating a hydroponic produce farm in Austin.

Celiac Disease (CD) is now widespread as one in 133 people are currently diagnosed, while there were only one in 150 in 2006. Much of the research concerning CD is still in the early stages, as formal epidemiological studies are relatively recent. CD is aggravated by the consumption of gluten, which is found mainly in wheat, rye, oats, and barley. Not surprisingly, the rising prevalence of CD has created a significant business opportunity for food manufacturers in developing products that are tailored to CD sufferers. While the entire Gluten-Free (GF) industry has been experiencing double digit growth rates, the expansion in available snack foods has outstripped all others. Observation of GF snack food prices suggests that food manufacturers are responding to high retail prices associated with GF foods. However, GF foods are often also advertised with other attributes that generally sell for a premium over conventional foods. Therefore, whether the high retail price for GF snack foods can be attributed specifically to the GF attribute is an empirical question. The objective of this research is to determine whether there is a retail-price premium for GF snack foods and, if there is, to estimate its magnitude. A hedonic pricing model is used to answer this question. Specifically, a hedonic pricing model was applied to a unique dataset of snack food products in order to estimate the marginal value for the GF attribute, while controlling for a number of other important attributes. Results show that the GF attribute is both economically and statistically significant, implying a premium of nearly $1.86 above gluten-containing products. Production costs for smaller manufacturers can be two to three times higher for GF foods relative to non-GF foods, but this still implies an excess premium of over $0.50 (assuming 40% margins). However, high premiums may not last as large retailers are utilizing their influence over suppliers to keep retail margins low. Therefore, the primary implication of the research is that the rapid growth in recent years can easily be explained on economic grounds for large agribusinesses, as this implies a major profit opportunity.

Description
Over the course of 2015-2017, the ASU-SCMA/UASGC Outreach program was developed at Arizona State University (ASU) to support both high school students and college students interested in supply chain management careers. In particular, the program targets the high school students of the Urban Assembly School for Global Commerce (UASGC) and the college students of the ASU Supply Chain Management Association (ASU-SCMA). High school students are partnered with college students in a year-long mentoring program that allows both parties to develop professional supply chain skills. The work of the ASU-SCMA/UASGC Outreach Program is particularly important because it provides UASGC with much needed resources to address urban poverty issues in New York using career and technical education. The Urban Assembly describes its student group as "at-risk, under-resourced youth," and of those youth: - 85% are low-income - 83% enter high school below grade level in at least one subject - 20% require Individualized Education Plans (Special Needs) (urbanassembly.org). The Outreach Program addresses the above issues by providing the high school students with collegiate mentors that develop supply chain and college readiness resources in the form of a case study, site tour, supply chain simulation and presentations. In order to be considered successful, the program must first, equip the high school mentees with tools and skills for a professional career, specifically supply chain management, that they would not otherwise be exposed to; and second, motivate the collegiate participants who are about to enter the workforce to continue to participate in mentoring throughout their careers. This program documents the efforts and results of the pilot year for the Outreach Program that took place from September 2016 through March 2017. Through this pilot program, it was determined that the ASU-SCMA/UASGC Outreach Program is effective and valuable. In fact, the program found that: - 75% of the high school students agreed or strongly agreed that the program helped them learn new business skills. - 75% of the high school students agreed that the program taught them new, interesting things about supply chain. - 75% of the high school students became more interested in college. 100% of the college mentors agreed or strongly agreed that they gained new and important supply chain and professional skills. The success of the pilot year has led to plans for the Outreach Program to become an annual project for ASU-SCMA. This is a program that will continue for the foreseeable future.

The restaurant opening process for "Muse & Market" was documented and evaluated. For my creative project, I served as the Director of Business Development for "Muse & Market" and assisted in the carrying out of activities including supplier selection, functional retail assembly and other key decision making. I paralleled this experience by researching best practices in the restaurant industry. I performed research by reviewing academic literature and online sources and by interviewing marketing managers and restauranteurs in New York City and Phoenix, AZ. I compiled a list of best practices based off of the commonalities from my research and interviews. I then compared these findings to what I experienced at Muse & Market to determine which of Muse & Market's launch preparation activities aligned with which best practices. I also identified areas of improvement for Muse & Market based on this comparison. Lastly I offered my key takeaways from my experience as an aspiring entrepreneur in the restaurant industry.
