Efficacy of Several Candidate Protein Biomarkers in the Differentiation of Vaginal from Buccal Epithelial Cells*

Abstract: Currently, there is no accurate method to differentiate vaginal epithelial cells from buccal epithelial cells in biological samples typically encountered in forensic casework. This study tested the expression of a selection of candidate proteins in buccal and vaginal epithelial cells. We investigated six candidate biomarkers, such as loricrin, vimentin, stratifin, cytokeratin 4, cytokeratin 13, small proline‐rich protein 2, and involucrin, using Western blot analysis on whole protein extracts and immunohistochemistry (IHC) on intact cells in an attempt to identify cell‐specific markers that would differentiate these cells by microscopy. Involucrin, loricrin, and stratifin showed differential expression during Western blot analysis and were carried through to IHC. Although proteins unique to vaginal epithelial cells and buccal epithelial cells were not identified from among the proteins tested, the increased expression levels of two proteins, loricrin and stratifin in vaginal cells, when compared to buccal cells, do provide encouraging results in the search for epithelial cell‐specific markers.     

Epidemiology of homicide-suicide events: Oklahoma, 1994-2001

In Oklahoma, all nonnatural deaths must be reported to the Office of the Chief Medical Examiner (ME), whose trained investigators report cause of death using a centralized, statewide, standardized reporting system. The purpose of this study was to determine temporal trends of Oklahoma homicide-suicide events and characterize the epidemiology of these events. By reviewing all ME reports of homicides and suicides from 1994 through 2001, we identified 73 homicide-suicide events resulting in 73 suicides and 89 homicides. Suicidal perpetrators of homicide-suicide events were most often white men aged >or=30 years who killed a current or ex-spouse or intimate partner. Homicide victims tended to be younger women the same race as their killer. Firearms were the predominant method of death in both homicides and suicides, with handguns used most frequently. Divorce/estrangement was the main contributing factor to these events, and the most common relationship type was possessive. The existence of a statewide, centralized, and computerized ME system and the ability to access the detailed information in the ME narratives were critical to identifying homicide-suicide events and obtaining the type of detailed information necessary to fully investigate these events.     

Jail drug and alcohol treatment program reduces recidivism in nonviolent offenders: a longitudinal study of Monroe County, New York's, Jail Treatment Drug and Alcohol Program

Substance abuse treatment has become the new fashion for reducing recidivism among inmates. But the question is, does this work? Various studies have been done tracking the same cohort of inmates over time to assess the validity of treatment. This study assesses one treatment program's success over 5 years to determine if drug and alcohol treatment reduces recidivism among nonviolent, short-term (sentence of less than a year) inmates. Monroe County's drug treatment program demonstrates that for 1 year after receiving the treatment, three different cohorts of nonviolent, short-term inmates (1995, 1998, and 2000) were found to be substantially less likely to be recidivists than control group inmates.     

What's looks got to do with it? Instructor appearance and student evaluations of teaching

Some studies suggest that instructors' looks are important determinants of their Student Evaluations of Teaching (SET) results. Yet the studies examining this proposition leave out many independent variables that have been found to be important determinants of SETs in the SET literature. This study adds in most such factors and finds that, controlling for these other factors, attractiveness has no effect in our data. We conclude that earlier findings indicating that instructor appearance is important are likely due to omitted variable bias. © 2005 by the Association for Public Policy Analysis and Management     

Will working from home become the ‘new normal’ in the public sector?

The COVID-19 pandemic compelled large sections of the workforce out of their workplaces and into their homes to work. Many commentators suggest this has forever changed how and where we work. This article analyses how Australia's biggest employers – state and federal governments – approached the transitions to working from home, and back into regular workplaces. It considers the timing of policy responses to the pandemic as one indicator of resistance to, or acceptance of, widespread working from home. The article also demonstrates previous resistance to working from home for public servants, and questions widespread conjecture that it will become the ‘new normal’.     

Strategic drift in international non‐governmental development organizations—putting strategy in the background of organizational change

Although the use of strategic planning has become widespread in INGDOs they have often been accused of strategic drift—continuous change in their strategic directions with plans only loosely coupled to their activities. However, the way that they prioritize their activities, and the reasons why strategic drift occurs has generally escaped in‐depth research. This article draws on detailed, qualitative research of strategic planning meetings at the executive levels in a major INGDO, carried out between July 2006 and December 2007 to identify the reasons why strategic drift occurs and the role of strategic planning. It was found that by deliberately crafting multiple, ambiguous, and ambitious strategies, managers were able to effect organizational change, not by literal strategy implementation, but by using these strategies as metaphors to harness consensus and legitimacy in key stakeholder groups. Senior managers utilize the symbols, language and deliberative arenas of formal strategic planning to effect organizational change; however, strategy, in rational terms, needs to be located in the background for its role to be properly understood. The research unpacks complex decision‐making processes in an INGDO and, contrary to normative literature, recommends that, in order to avoid inflationary planning, managers should not take their strategy literally.

Opening Windows on Surveillance: the Scholarship of Gary Marx

Gary Marx’s work on surveillance is important to those concerned about the causes and implications of modern surveillance technologies. This essay addresses the themes of reality, complexity, and transdisciplinarity that are prominent in all of Marx’s work including his 2016 book, Windows into the Soul: Surveillance and Society in an Age of High Technology.
