Entrepreneurship, Creativity, and Local Food Systems: Essays on Regional Economic Development in South Carolina

Within the existing economic development literature, there is a well-established linkage between the presence of skilled human capital and economic growth. A subset of this literature has focused on the role that a specific type of skilled human capital, known as the “creative class,†may play in facilitating regional economic development. This dissertation builds upon the existing creative class literature by examining the factors that have attracted the creative class to the state of South Carolina. In addition, this research gives special attention to the entrepreneurial activities of creative class professionals who engage in small-scale farming. Recent interest surrounding the economic, social, and environmental benefits of small-scale farming has led researchers and development practitioners to increasingly examine the role that local food systems may play in the regional development process. Accordingly, this dissertation examines how small-scale farm operators may be contributing to their communities and local economies by engaging in knowledge-intensive, entrepreneurial activities. This dissertation includes three manuscripts related to the creative class and local food systems in South Carolina. Manuscript One examines the geographical, physical, and socioeconomic characteristics that may attract members of the creative class to certain communities in South Carolina. This research provides insight into the factors that may allow some rural or less populated areas to attract high-quality human capital. Manuscript Two transitions into an examination of entrepreneurship and local food systems and specifically, explores a linkage between small-scale farm operators and the creative class. Manuscript Two is intended to provide insight into the role that local food systems may play in facilitating local economic development and should be especially relevant to rural or less populated areas looking to implement an entrepreneurship-led development strategy. Lastly, Manuscript Three explores the factors that may facilitate the development of well-functioning local food systems in certain South Carolina counties. This research may be especially relevant to development practitioners who are considering ways to improve the overall functioning of their local food systems

Model refactoring using examples: a search‐based approach

One of the important challenges in model‐driven engineering is how to improve the quality of the models' design in order to help designers understand them. Refactoring represents an efficient technique to improve the quality of a design while preserving its behavior. Most of existing work on model refactoring relies on declarative rules to detect refactoring opportunities and to apply the appropriate refactorings. However, a complete specification of refactoring opportunities requires a huge number of rules. In this paper, we consider the refactoring mechanism as a combinatorial optimization problem where the goal is to find good refactoring suggestions starting from a small set of refactoring examples applied to similar contexts. Our approach, named model refactoring by example, takes as input an initial model to refactor, a set of structural metrics calculated on both initial model and models in the base of examples, and a base of refactoring examples extracted from different software systems and generates as output a sequence of refactorings. A solution is defined as a combination of refactoring operations that should maximize as much as possible the structural similarity based on metrics between the initial model and the models in the base of examples. A heuristic method is used to explore the space of possible refactoring solutions. To this end, we used and adapted a genetic algorithm as a global heuristic search. The validation results on different systems of real‐world models taken from open‐source projects confirm the effectiveness of our approach.

Управление финансовым состоянием предприятия (на примере СП ОАО «Спартак»)

The purpose of this paper is to explore the characteristics of information systems (IS) maintenance within an IT and organizational setting. We discuss the characteristics of maintenance objects’ focus and content. Our results are based on qualitative case studies. In this paper a case study of a Swedish Bank is used to illustrate our discussion. Our findings show that maintenance objects can be defined by processes and/or functions or products and/or services within an organizational setting. This is done in order to increase a business perspective in maintenance management and to clarify roles of responsibility for organizational changes required from new IT capabilities. According to our findings maintenance objects can contain business solutions and IT solutions. This implies that business beneficial maintenance is supported by close cooperation between actors from the organizational setting and the IT organization. The result of the paper is a characterization of IS maintenance through definition of maintenance objects’ focus and content

Information and learning technology (ILT) adoption among career and technical teachers in Malaysia

This study investigated the diffusion of Information and Learning Technology (ILT) among career and technical educators in Malaysia. It was conducted at a large career and technical institute and utilized a non-experimental research approach. The results show that a majority of faculty members reported that ILT is important as a teaching tool, yet also suggest that few faculty members use it in their teaching practice. Compared to males, female faculty members owned significantly more personal computers. Faculty members who owned a personal computer rated higher on the variables of usage, knowledge, satisfaction, and support, and lower on “barrier to use” than those who did not own a personal computer. The findings revealed that career and technical faculty members were most comfortable using familiar technologies including the Internet, word processing, and presentation software. The study suggests that career and technical training facilities in Malaysia should address general barriers and increase both technological and pedagogical support to successfully implement ILT in teaching and learning practice

An empirically-based characterization and quantification of information seeking through mailing lists during Open Source developers' software evolution

Context Several authors have proposed information seeking as an appropriate perspective for studying software evolution. Empirical evidence in this area suggests that substantial time delays can accrue, due to the unavailability of required information, particularly when this information must travel across geographically distributed sites. Objective As a first step in addressing the time delays that can occur in information seeking for distributed Open Source (OS) programmers during software evolution, this research characterizes the information seeking of OS developers through their mailing lists. Method A longitudinal study that analyses 17 years of developer mailing list activity in total, over 6 different OS projects is performed, identifying the prevalent information types sought by developers, from a qualitative, grounded analysis of this data. Quantitative analysis of the number-of-responses and response time-lag is also performed. Results The analysis shows that Open Source developers are particularly implementation centric and team focused in their use of mailing lists, mirroring similar findings that have been reported in the literature. However novel findings include the suggestion that OS developers often require support regarding the technology they use during development, that they refer to documentation fairly frequently and that they seek implementation-oriented specifics based on system design principles that they anticipate in advance. In addition, response analysis suggests a large variability in the response rates for different types of questions, and particularly that participants have difficulty ascertaining information on other developer's activities. Conclusion The findings provide insights for those interested in supporting the information needs of OS developer communities: They suggest that the tools and techniques developed in support of co-located developers should be largely mirrored for these communities: that they should be implementation centric, and directed at illustrating "how" the system achieves its functional goals and states. Likewise they should be directed at determining the reason for system bugs: a type of question frequently posed by OS developers but less frequently responded to

Engineering context-aware systems and applications:A survey

Context-awareness is an essential component of systems developed in areas like Intelligent Environments, Pervasive & Ubiquitous Computing and Ambient Intelligence. In these emerging fields, there is a need for computerized systems to have a higher understanding of the situations in which to provide services or functionalities, to adapt accordingly. The literature shows that researchers modify existing engineering methods in order to better fit the needs of context-aware computing. These efforts are typically disconnected from each other and generally focus on solving specific development issues. We encourage the creation of a more holistic and unified engineering process that is tailored for the demands of these systems. For this purpose, we study the state-of-the-art in the development of context-aware systems, focusing on: (A) Methodologies for developing context-aware systems, analyzing the reasons behind their lack of adoption and features that the community wish they can use; (B) Context-aware system engineering challenges and techniques applied during the most common development stages; (C) Context-aware systems conceptualization

Assessing the Effects of Personal Characteristics and Context on U.S. House Speakers’ Leadership Styles, 1789-2006

Research on congressional leadership has been dominated in recent decades by contextual interpretations that see leaders’ behavior as best explained by the environment in which they seek to exercise leadership—particularly, the preference homogeneity and size of their party caucus. The role of agency is thus discounted, and leaders’ personal characteristics and leadership styles are underplayed. Focusing specifically on the speakers of the U.S. House of Representatives from the first to the 110th Congress, we construct measures of each speaker’s commitment to comity and leadership assertiveness. We find the scores reliable and then test the extent to which a speaker’s style is the product of both political context and personal characteristics. Regression estimates on speakers’ personal assertiveness scores provide robust support for a context-plus-personal characteristics explanation, whereas estimates of their comity scores show that speakers’ personal backgrounds trump context
