An Experimental Template for Case Study Research

Methods are usually classified as either "experimental" or "observational," a dichotomy that has governed social science research for centuries. By implication, this dichotomization precludes a consideration of experimental strategies in case study work. Yet, we argue that one gains purchase on the tasks of research design by integrating the criteria traditionally applied to experimental work to all research in the social sciences—including case study work, the focus of this article. Experimental research designs aim to achieve variation through time and across space while maintaining ceteris paribus assumptions, thus maximizing leverage into the fundamental problem of causal inference. We propose to capture these multiple criteria in a four-fold typology: (1) A Dynamic comparison mirrors laboratory experimentation through the use of both temporal and spatial variation; (2) A Longitudinal comparison employs temporal variation; (3) A Spatial comparison exploits variation through space; and (4) A Counterfactual comparison relies on imagined comparison. All comparison case study research designs can be slotted into one of these four categories. Moreover, the typology illustrates in a concise fashion the ways in which case study research designs attempt to mimic the virtues of experimental design and the degree to which they succeed. The classic experiment, with manipulated treatment and randomized control, thus provides a useful template for discussion about methodological issues in experimental and observational contexts.     

Civil Service Reform as National Security: The Homeland Security Act of 2002

The events of 9/11 have influenced policy making in public administration. The Homeland Security Act of 2002, which created the Department of Homeland Security, contained language that empowered the secretary of homeland security and the director of the Office of Personnel Management to establish a personnel management system outside the normal provisions of the federal civil service. Why did civil service reform succeed as part of this legislation when previous attempts at large‐scale reform had failed? A case analysis of the enactment of civil service reform in the Homeland Security Act points to theories of policy emergence and certain models of presidential and congressional policy making. In this case, civil service reform became associated with national security instead of management reform. An assessment of the rhetorical arguments used to frame this policy image offers a powerful explanation for the adoption of the personnel management reforms in the Homeland Security Act. This case has implications for understanding how policy makers might approach future management reform agendas.     

Toxic waste as public business

Abstract: That there is some public responsibility for toxic waste management is a point widely taken for granted. However, there has been controversy over whether toxic waste management should become the responsibility primarily of a public corporation. Proposals for a public corporation to assume such responsibility have been advanced in Canada at the provincial level with widely varying outcomes. Through a comparison of three cases – British Columbia, Alberta, and Ontario – this article examines the salient issues in this policy debate and questions the prevailing mode of problem definition in order to propose a contrasting approach to public responsibility. Sommaire: On s'accorde généralement pour dire qu'il existe une certaine responsabilité publique face à la gestion des déchets toxiques. Par contre, la question de savoir si la responsabilité de gérer ces déchets devrait incomber surtout à une société d'État a fait, elle, l'objet de controverses. Dans les provinces où on a proposé qu'une société d'État prenne en charge cette responsabilité les résultats ont été fort variés. En comparant trois cas, ceux de la Colombie-Britannique, de l'Alberta et de l'Ontario, cet article examine les principales questions de ce débat et met en doute la façon actuelle de définir le problème, afin de proposer une approche différente en ce qui concerne la responsabilité publique.     

Rebuilding Ukraine's hollow State: Developing a democratic public service in Ukraine

This article describes assistance that is being provided as part of an institution building project with a view to making a lasting impact on the development of a democratic public service of Ukraine. It explains the nature of the project and the strategies adopted to overcome difficulties. It compares and contrasts approaches adopted by technical assistance projects in assisting administrative reform. It also examines the special nature of the Ukraine project that arises out of the distinctive context and needs of Ukraine. The article continues by examining the role of external assistance in validating the Ukrainian Institute of Public Administration and Local Government's Masters in Public Administration and the contribution made to the development and delivery of the Masters programme. A special feature of the project is the series of one-month internships when IPALG students visit London. The internship programme allows students to identify aspects of UK experience relevant to changes that Ukraine wishes to make in its administrative culture. As part of this programme, students are placed in government organizations and NGOs. The placements are complemented by a series of change management seminars that enable students to evaluate options for change, to assess their own role in the change process and recognize the key stages in the change process. The project team has undertaken a full evaluation of the first presentation of the programme and the article presents the findings.

Behavior problems of handicapped adolescent female students

Adolescent girls aged 12 through 16 years, identified as either educable mentally retarded, behaviorally disordered, learning disabled, or nonhandicapped, were rated by their teachers on the Behavior Problem Checklist. Analysis of these ratings revealed significant differences for pupil category, Behavior Problem Checklist dimension, and category-by-dimension interaction. Behaviorally disordered students showed a greater degree of maladjustment than the retarded and nonhandicapped students on all four checklist dimensions, and exceeded the learning disabled on three dimensions (not Personality Problem). Implications for further research and special educational practices based on the present findings are discussed.Received Ed.D. from University of Virginia.

The use of SEM/EDS analysis to distinguish dental and osseus tissue from other materials

With increasing frequency, relatively small, fragmentary evidence thought to be osseous or dental tissue of human origin is submitted to the forensic laboratory for DNA analysis with the request for positive identification. Prior to performing DNA analysis, however, it is prudent to first perform a presumptive test or "screen" to determine whether the questioned material may be eliminated from further consideration. When material is shown not to be consistent with bone/teeth, DNA testing is not performed. When such determinations cannot be made from gross morphological features, elemental analysis can be indicative. This presumptive test is made possible by applying scanning electron microscopy/energy dispersive X-ray spectroscopy (SEM/EDS) in conjunction with an X-ray spectral database recently developed by the FBI laboratory. This database includes spectra for many different materials including known examples of bone and tooth from many different contexts and representing the full range of taphonomic conditions. Results of SEM/EDS analysis of evidence can be compared to these standards to determine if they are consistent with bone and/or tooth and, if not, then what the material might represent. Analysis suggests that although the proportions and amounts of calcium and phosphorus are particularly important in differentiating bone and tooth from other materials, other minor differences in spectral profile can also provide significant discrimination. Analysis enables bone and tooth to be successfully distinguished from other materials in most cases. Exceptions appear to be ivory, mineral apatite, and perhaps some types of corals.     

An improved method for post-PCR purification for mtDNA sequence analysis

Mitochondrial DNA (mtDNA) analysis of forensic samples typically is performed when the quantity and quality of DNA are insufficient for nuclear DNA analysis or when maternal relatives may be the only reference source. Many of the steps required in the analytical process are both lengthy and labor intensive. Therefore, improvements in the process that reduce labor without compromising the quality of the data are desirable. The current procedure requires purification of the amplicons by centrifugal filtration after PCR and prior to cycle sequencing. Because this method requires several manipulations to perform, alternate cleanup procedures were investigated. These include the use of 1) Qiagen QlAquick PCR Purification columns, 2) Concert Rapid PCR Purification columns, and 3) ExoSAP-IT reagent. When the yield of purified amplicons, quality of the sequence profile, and ease of assay were evaluated, the use of ExoSAP-IT reagent for post-amplification purification was chosen to replace the filtration method.
