Downside Risk Optimization Of The Thrift Savings Plan Lifecycle Fund Portfolios, Matthew C. Beck
Downside Risk Optimization Of The Thrift Savings Plan Lifecycle Fund Portfolios, Matthew C. Beck
Theses and Dissertations
The Thrift Savings Plan (TSP), the defined benefit contribution plan for the US Government, introduced the asset allocation Lifecycle (L) Funds in August 2005. These funds seek to minimize risk and maximize expected portfolio return via mean-variance optimization (MVO). The purpose of this thesis is to investigate and examine the efficiency of the TSP L Funds and create alternative L Fund portfolios via downside risk optimization (DRO). Whereas MVO minimizes the portfolio variance (standard deviation), DRO seeks to minimize the risk below an investor’s minimal acceptable return in the market, defined as the Co-Lower Partial Moment (CLPM). The research team …

A Linear Programming Approach For Determining Travel Cost Minimizing Ecss Training Locations, Jason S. Boerboom
Theses and Dissertations
The Department of Defense is currently operating in a fiscally constrained environment, and Air Force leaders are pressured to minimize spending while pursuing mission critical objectives. Personnel travel usurps a significant portion of the Air Force’s annual operations and maintenance (O&M) budget each year, but receives little attention with respect to cost saving strategies. During the Air Force’s implementation of the Expeditionary Combat Support System (ECSS), in which over 250,000 end-users will require training, it is vital that the Department determine the training locations that minimize costs incurred through personnel travel. This thesis seeks to determine which potential ECSS training …

A Study Of Formal And Informal Mentoring In The United States Air Force, Russell H. Gheesling
Theses and Dissertations
Mentoring has been identified as a significant contributor to employee performance and development. Debate has come about as result of implementation of formal mentoring programs where mentors are assigned to protégés as opposed to informal relationship formed out of mutual respect and liking. Secondary data, including measures of leader member exchange, similarity, contact time, and others, were used from a 1998 survey of company grade officers (protégés) and their formal and informal mentors. Analysis of Variance compared mean values between formally and informally mentored protégés. Additionally, a logistic regression was used to understand the impact that different measures had on …
Understanding The Effectiveness Of Performance Management Practices, Ross T. Johnston
Understanding The Effectiveness Of Performance Management Practices, Ross T. Johnston
Theses and Dissertations
Effective employee management is an essential element for achieving and sustaining a competitive advantage. Through a variety of performance management practices organizations can translate competitive strategies into individual performance expectations and transform employee potential into desired organizational outcomes. Despite the promise of robust performance management practices, a significant research gap exists between the scientific research in Organizational Behavior (OB) and the performance management practices espoused by the “practitioners.” The purpose of this thesis research is to explore a set of performance management practices as an initial step toward providing direct, empirical support for the linkages between performance management practices, the …
