Media analyses based on Microsoft NTFS file ownership

The ever-increasing size of digital media presents a continuous challenge to digital investigators who must rapidly assess computer media to find and identify evidence. To meet this challenge, methods must continuously be sought to expedite the examination process. This paper investigates using the file ownership property as an analytical tool focusing on activity by individuals associated with the computer. Research centered on the New Technology File System (NTFS), which is the default file system in Microsoft Windows Operating System (OS). This was done because Microsoft's worldwide market penetration makes Windows and NTFS the most likely OS and file system to be encountered in digital forensic examinations. Significantly, digital forensic software now allows examination of NTFS file attributes and properties including the ownership property. The paper outlines potential limitations regarding interpreting ownership findings, and suggests areas for further research. Overall, file ownership is seen as a potentially viable new digital forensic tool.     

For the Guidance of Martians: A Reply to Martin Smith on British Politics Textbooks

A recent review article in the British Journal of Politics and International Relations made a number of criticisms about the supposed lack of innovation and theoretical rigour found in current British politics textbooks. Jones and Robins constructively engage the points made in the article and argue that the criticisms made are only partly valid. They conclude that, within the obvious confines of a basic text, there is more on offer to students than there has ever been and that the success of these textbooks provides publishers with the means to cross-subsidise minority interest scholarship.     

Financial incentives and welfare reform in the United States

This paper uses a microsimulation model to ask whether welfare recipients in the United States would work full‐time if offered an earnings supplement that was conditioned on full‐time employment. The simulations suggest that the earnings supplement would increase full‐time employment, with little additional cash transfer cost to the government. In contrast, financial incentives currently being used by many of the states are increasing employment and income, but are encouraging primarily part‐time employment. Encouraging full‐time employment is particularly important in light of new time limits on welfare receipt. Faced with a loss of welfare benefits, many recipients may find that part‐time earnings do not allow them to be economically self‐sufficient. © 2001 by the Association of Public Policy Analysis and Management.
