An Investigation Of The Factors Contributing To The Development Of Poorly Defined Is Strategies For Firms In The United States, Karen B. Lacaden

CCAC Theses and Dissertations

Although empirical research has shown that a clearly defined information system (IS) strategy has a positive impact to a firm’s performance and a poorly defined IS strategy has a negative impact to a firms’ performance, firms still develop poorly defined IS strategies. Further compounding the problem, research has revealed that 87% of the business executives believe information systems are a critical enabler to their firms' strategic realization, yet only 33% of business executives involve the Chief Information Officer (CIO) in their firm’s business strategy development. The main goal of this research study is to empirically identify factors which impact development …

The Influence Of Exploration On External Corporate Venturing Activity, Varkey K. Titus Jr., Jenny M. House, Jeffrey G. Covin

Department of Management: Faculty Publications

We utilize the exploration/exploitation framework to examine how a firm’s engagement in exploration influences its portfolio of external corporate venturing (ECV) activities. Three forms of equity-based ECV are considered: corporate venture capital investments, joint ventures, and acquisitions. The organizational learning literature is used to investigate how a firm’s engagement in exploration influences its usage of acquisitions relative to its overall portfolio of ECV activities. The investing firm’s industry technological dynamism is posited as a moderator of the relationship between exploration and the relative usage of acquisitions. Utilizing a sample of 1,326 firm-year observations between 1996 and 2008, we find that …

Quality Management And Innovation: New Insights On A Structural Contingency Framework, Dara Schniederjans, Marc Schniederjans

Racial Differences In Job Attribute Preferences: The Role Of Ethnic Identity And Self-Efficacy, Jakari N. Griffith, Gwendolyn M. Combs

Department of Management: Faculty Publications

Using a sample of 149 white and 190 black business students, the authors examined racial differences in job attribute preferences. Results of this study indicate there were significant racial differences in 19 of 21 job attributes examined, with black students placing greater importance on job attributes than white students. Investigation of the mechanisms contributing to this difference reveals that the relationship between race and job attribute preferences was mediated by ethnic identity. Furthermore, the relationship between ethnic identity and job attributes was moderated by personal efficacy, with higher self-efficacy levels leading to greater importance placed on job attributes.

Autonomy In The California Disability Services System, Lisa Ann S. Carbone

Walden Dissertations and Doctoral Studies

Legislation concerning California residents with intellectual and developmental disabilities (ID/DD) requires recipients of services to be treated as independent individuals while emphasizing self-determination. At the same time, under regulatory procedures, recipients are considered dependent on the delivered services and not self-determinant. Neither the California Department of Developmental Services nor the trade associations representing community service providers have established a unified, systematic practice to support self-determination. This phenomenological study explored the experience of adults with ID/DD working toward self-determination.

Specifically, it explored how medical and social models contribute to shaping and actualizing the independence of this population. Interviews with eight adults …
