The not-for-profit community serves a vital societal role. Guided by the systems-theory, the purpose of this qualitative phenomenological study was to identify ways not-for-profit agencies could be more fiscally sound during difficult economic times and plan for uncertain futures. Face-to-face recorded interviews with 20 chief executives from different not-for-profit corporations in western Pennsylvania, were conducted to examine their professional lived experiences in order to collect best practices by which each executive dealt with difficult economic times. Structured interviews consisted of 8 questions that probed different aspects of the phenomena of dealing with fiscal challenges. Transcribed data were coded for both a priori and emergent themes and were categorized according to a cross-case similarities and differences of the specific responses of the CEOs. The convergent across-case findings of the current study indicated that leaders should (a) have a strategic plan, (b) utilize metrics to evaluate outcomes against goals, and (c) be willing to adjust plans accordingly. Almost all of executives indicated that remaining fiscally healthy was critical so that his organization could achieve its primary mission of serving their community. Not-for-profit organizations provide medical care to the homeless, care for the needs of the elderly, and provide specific services to children with metal disabilities helping them to become more productive. The current study contributes to positive social change by informing best practices regarding how not-for-profit corporations can continue to provide these critical social services through sustainable business practices, especially during those difficult economic times when their services are most needed.

The lean inventory concept has been shown to streamline operations and improve efficiency in a retail environment. The negative side of the practice is that limited inventories increase the risk of stockouts, where a routinely available product is missing and the retailer is not able to meet customer demands. The purpose of this exploratory case study was to examine stockouts as an event and document their effects on changes in customer attitudes and behaviors. Guided by a constructivist conceptual framework, the research question explored how stockout experiences affected customers' purchasing behaviors and loyalty to brand and retailer. A survey containing both open-ended and categorical response elements was validated through a pilot study and used to collect data from 40 randomly selected participants shopping at a retail mall in eastern Pennsylvania. Data coding for qualitative data consisted of 3 sequential stages of open, axial, and selective coding into a priori themes. Categorical responses were employed in downward analyses that revealed patterns in the qualitative data. The results indicated that repeated stockout experiences decreased customers' loyalty to brand and retailer and caused customers to abandon both retailers and brand. Respondents indicated that stockout impacts can be buffered through improved inventory management and better customer service. Specific recommendations included monetary incentives, personal contacts, coupons, and item discounts. Results of this study will enable retailers to gain deeper understanding of how stockout affects customers shopping experiences and loyalty, and offer mitigation measures to improve both. Results will provide a positive change to both consumers and retailers, where shoppers will enjoy pleasant shopping experiences and retailers will maintain their competitive advantage through loyalty of their customer base.

<p>This study introduces a new model for the planar maximal covering location problem (PMCLP) under different block norms. The problem involves locating p facilities anywhere on the plane in order to cover the maximum number of n given demand points. The generalization we introduce is that distance measures assigned to facilities are block norms of different types and different proximity measures. This problem is handled in three phases. First, a simple model based on the geometrical properties of the block norms' unit ball contours is formulated as a mixed integer program (MIP). The MIP formulation is more general than previous PMCLP's and can handle facilities with different coverage measures under block norm distance and different setup cost, and capacity. Second, an exact solution approach is presented based on: (1) An exact algorithm that is capable of handling a single facility efficiently. (2) An algorithm for an equivalent graph problem--the maximum clique problem (MCP). Finally, the PMCLP under different block norms is formulated as an equivalent graph problem. This graph problem is then modeled as an unconstrained binary quadratic problem (UQP) and solved by a genetic algorithm. Computational examples are provided for the MIP, the exact algorithm, and the genetic algorithm approaches.</p> / Doctor of Philosophy (PhD)

<p>This study describes algorithms for the solution of several single facility location problems with maximin or minimax objective functions. Interactive computer graphical algorithms are presented for maximizing the minimum rectilinear travel distance and for minimizing the maximum rectilinear travel distance to a number of point demands when there exist several right-angled polygonal barriers to travel. For the special case of unweighted rectilinear distances with barriers, a purely numerical algorithm for the maximin location problem is described. An interactive computer graphical algorithm for maximizing the minimum Euclidean, rectilinear, or general l$\sb{\rm p}$ distance to a number of polygonal areas is described. A modified version of this algorithm for location problems with the objective of minimizing the maximum cost when the costs are non-linear monotonically decreasing functions of distance is presented. Extension of this algorithm to problems involving the minimization of the maximum cost when the costs are functions of both distance and direction is discussed using asymmetric distances.</p> / Doctor of Philosophy (PhD)

<p>This study is divided into two main parts. The first section deals with mathematical properties of distance functions. The ℓp norm is analyzed as a function of its parameter p, leading to useful insights for fitting this distance measure to a transportation network. Properties of round norms are derived, which allow us later to generalize some well-known results. The properties of a norm raised to a power are also investigated, and these prove useful in our subsequent analysis of location problems with economies or dis-economies of scale. A positive linear combination of the Euclidean and the rectangular distance measures, which we term the weighted one-two norm, is introduced. This distance function provides a linear regression model with interesting implications on the characterization of transportation networks. A directional bias function is defined, and examined in detail for the ℓp and weighted one-two norms. In the second part of this study, several properties are derived for various forms of the continuous minisum location model. The Weiszfeld iterative solution procedure for the standard Weber problem with ℓp distances is also examined, and global and local convergence results obtained. These results are extended to the mixed-norm problem. In addition, optimally criteria are derived at non-differentiable points of the objective function.</p> / Doctor of Philosophy (PhD)

Family businesses represent a key economical asset in the global economy. Leaders of family businesses have implemented internationalization as a key strategy to enhance sustainability and increase profitability in a hypercompetitive global marketplace. Guided by the Uppsala model, the purpose of this case study was to explore how Saudi family business leaders have planned and implemented internationalization. Three leaders from different international Saudi family businesses participated in semistructured interviews. The participants described their experience in achieving successful internationalization for their family businesses. After analyzing the interview data and validating through member checking, 3 main themes emerged: (a) the characteristics of the family business to compete internationally, (b) the characteristics of a suitable international market for family businesses to internationalize, and (c) the characteristics of a successful internationalization opportunity for a Saudi family business. In order to internationalize, Saudi family business leaders identified having a proper strategy, financial capability, qualified resources, well-structured policies, and globally-standardized products or services. Family business leaders should target the international market that is stable, that is secure with regulations, and that is welcoming to foreign investments. Each internationalization opportunity should have close psychic distance, available relationships in the international market, targeted family business motives, demonstrated existing market demand with the ability to satisfy, and proper timing. The findings may promote social change in Saudi family businesses by identifying essential characteristics to maintain the companies' existence and offer a roadmap to compete internationally.

The purpose of this study was to examine the factors involved in successful second-generation legacy perpetuation in independent insurance agencies. This study examined the role of parent and child throughout the process in an effort to thwart the current high failure rates. This research aims to promote healthy business activity, improve success and sustainability, and add positive social stewardship in communities. Education and preparation of successor, timing of transition, financial considerations, and processes of succession were addressed. Two frameworks guided this study: Bertalanffy's systems theory and Bandura's theory of self-efficacy. Nonrandom, purposeful samples of 3 profitable, second-generation agency owners of 10 years or more in Pennsylvania provided information rich, in-depth interviews. Interviews were transcribed for patterns and cross-case analysis helped reveal commonalities. Themes identified suggested that successful agencies hired professional consultants. A key finding was having a written plans detailing payoff considerations. The primary recommendation from the study is to hire a professional to guide the process. This study has implications for positive social change as it contributes to the education of legacy-perpetuated transition and prevention of failure. Helping to keep family businesses thriving can, in turn, promote positive social change within communities.

Organizations need to constantly innovate to be relevant in a highly competitive market. Intrapreneurship, defined as entrepreneurship within the organization, is one method to bring about this constant innovation. The purpose of this study was to explore intrapreneurship, through a multiple case study, to gain a better understanding of which business strategies can foster successful intrapreneurship initiatives. The theories of Pinchot and Porter on intrapreneurship and organizational competitiveness formed the theoretical lens for this study. The sample for this study consisted of 5 business leaders in Atlanta, Georgia who had demonstrated intrapreneurship in their organization by encouraging their employees to pursue this method of innovation. Interviews took place with the leaders, and their collected narratives were analyzed for recurring themes. Additional pertinent financial data analysis was included for triangulation purposes. Emergent themes included the need for transformational leadership, the need for innovation at all levels of the organization, acceptance of failure and risk, facilitating empowerment, the beneficial link between intrapreneurship and operations management, recognition and rewards for employees expressing their creativity, company culture versus multicultural employees, and the need for creativity and competitiveness. These findings could bring about social change for employees through employee engagement and self-satisfaction. Employees have an opportunity to express their creativity through intrapreneurship initiatives.

Lack of employee engagement in the workplace is one of the leading causes of lost productivity in the United States, estimated to cost organizations between $450 to $550 billion per year. The purpose of this single case study was to explore the strategies that some business managers in the chemical industry use to engage employees and increase productivity. The population for the study consisted of 5 small chemical business managers of a chemical company in the northeastern United States that demonstrated success in engaging employees. The conceptual framework for the study was social exchange theory. Data were collected from small business managers via semistructured interviews detailing participants' strategies in engaging employees in the workplace and from company physical artifacts such as website, posters, bulletins, and signage. The collected data were transcribed, and member checking was completed to validate the credibility and trustworthiness. Yin's 5-step data analysis process for a case study and the main words in context analysis were used to analyze data. Three themes discovered in the study were: leadership support, effective communication, and recognition and reward. The findings from this study revealed that chemical business managers used strategies to influence employee engagement in the workplace. The impact of positive social change includes providing insights for managers on strategy implementation for employee engagement in the workplace to increase organizational productivity and stability, which could lead to a healthy economy in the community and employees contributing positively to communities and supporting their families.
