    Bridging the Rural - Urban Digital Divide in Residential Internet Access
    Whitacre, Brian E. (Virginia Tech, 2005-09-01)
    This dissertation explores the persistent gap between rural and urban areas in the percentage of households that access the Internet at home (a discrepancy commonly known as the "digital divide"). The theoretical framework underlying a household's Internet adoption decision is examined, with emphasis on the roles that household characteristics, network externalities, and digital communication technology (DCT) infrastructure potentially play. This framework is transferred into a statistical model of household Internet access, where non-linear decomposition techniques are employed to estimate the contributions of these variables to the digital divide in a given year. Differences in Internet access rates between years are also analyzed to understand the importance of temporal resistance to the continuing digital divide. The increasing prevalence of "high-speed" or broadband access is also taken into account by modeling a decision process where households that choose to have Internet access must decide between dial-up and high-speed access. This nested process is also decomposed in order to estimate the contributions of household characteristics, network externalities, DCT infrastructure, and temporal resistance to the high-speed digital divide. The results suggest that public policies designed to alleviate digital divides in both general and high-speed access should focus more on the broader income and education inequities between rural and urban areas. The results also imply that the current policy environment of encouraging DCT infrastructure investment in rural areas may not be the most effective way to close the digital divide in both general and high-speed Internet access.

    The Relative Importance of Selected Variables on the Employment Consistency of Virginia Ex-Offenders
    Onyewu, Chinonyerem Nonye Chidozie (Virginia Tech, 2009-02-06)
    To decrease the steady rise in the prison population, we must deter ex-offenders from re-offending and recidivating, once they have been released. For ex-offenders, finding employment is critical to successful post-release re-integration which can help reduce the chances of them recidivating. Ex-offenders who are consistent in their employment patterns are less likely to return to a life of crime. This study investigated the relative importance and significance of 11 selected variables on four separate levels of employment consistency. The selected variables were chosen based on what has been identified in the literature as effecting employment patterns of ex-offenders and the general population, and what data was reliable and available. The study group consisted of 2,314 male Virginia ex-offenders released in fiscal year 2001. The results revealed that the variables of time served, career and technical education program completions, educational level, age at release, race, and being convicted of a violent offense were positive predictors of employment consistency. On the other hand, having a record of minor infractions and being a repeat offender were associated with decreasing employment consistency in the analysis. The findings of the study suggest that it is important for offenders to make changes in the ways they think and their attitudes. This can be accomplished by taking advantage of opportunities in prison to participate in rehabilitative services and educational programs. In addition, as offenders get older they tend to abandon criminal ways of thinking, and once released they are more apt to stay employed. Furthermore, the influence of the race variable did not affect the study group of ex-offenders as anticipated.
