Custom Windows Patching Methodology - Comparative Analysis, Brent Michael Henderson

Electronic Theses and Dissertations

Windows Server Update Services has been a common mainstay among organizations with a heavy footprint of Windows operating systems since it was originally released as Software Update Services in 2002. While the product has grown in scope, the primary allure remains the same: WSUS offers organizations greater control over the patches that are released to their environment and saves bandwidth by allowing a centralized device to download and offer patches to internal clients rather than having each of those clients download the content they require from the Internet. Unfortunately, the product has a structural limitation in that it lacks the …

Are You Ready? A Proposed Framework For The Assessment Of Digital Forensic Readiness, Andres Felipe Diaz Lopez

Electronic Theses and Dissertations

This dissertation develops a framework to assess Digital Forensic Readiness (DFR) in organizations. DFR is the state of preparedness to obtain, understand, and present digital evidence when needed. This research collects indicators of digital forensic readiness from a systematic literature review. More than one thousand indicators were found and semantically analyzed to identify the dimensions to where they belong. These dimensions were subjected to a q-sort test and validated using association rules, producing a preliminary framework of DFR for practitioners. By classifying these indicators into dimensions, it was possible to distill them into 71 variables further classified into either extant …

The Landwarnet School, The Army Learning Model, And Appreciative Inquiry: How Is A Centralized Training Organization Improved By Introducing Decentralization?, Lisa Jayne Stamper

Electronic Theses and Dissertations

This exploratory, qualitative case study describes how a centralized training organization (LandWarNet School) was improved by introducing decentralization (Army Learning Model) toward “the best competitive position” or "sweet spot," defined by Brafman and Beckstrom (2006) as “enough decentralization for creativity, but sufficient structure and controls to ensure consistency” (pp. 189, 191). Any presence of the six chaordic elements of a decentralized organization, as described by Hock (1999), was also considered.

LandWarNet School (LWNS) trains approximately 6000 US Army Soldiers annually and is centrally organized. The new Army Learning Model (ALM) is a vision for a more decentralized training approach where …

Stakeholder Perceptions Of A University Response To Crisis, Katherine M. Kelley

This study attempts to define consumer engagement and develop a conceptual framework of consumer engagement, addressing antecedents of consumer engagement in online context. Moreover, some situational and social media usage-related factors are incorporated into the framework. A set of propositions are …

The Impact Of The User-It Artifact Interaction On Technology Implementation And Value: Mobile Social Networking And Mobile Social Capital, Donghyun Kim

Electronic Theses and Dissertations

Despite investment and cutting-edge features, the majority of new mobile phone subscribers have adopted low-cost handsets instead of the latest mobile devices (Karjaluoto et al., 2005). According to the U.S. Census Bureau report, only 37% of cell phone users selected a smartphone in 2007. The Census Bureau forecasted the figure would increase by less than 10% in 2008. However, only 24% of cell phone users owned a smartphone in 2010, 27 % in 2011 and 30% in 2012. Therefore, the purpose of this study is to propose a conceptual model of the impact of mobile social capital on mobile networks …
