Pitfalls of Computed Tomography 3D Reconstruction Models in Cranial Nonmetric Analysis*

Many studies in the literature have highlighted the utility of virtual 3D databanks as a substitute for real skeletal collections and the important application of radiological records in personal identification. However, none have investigated the accuracy of virtual material compared to skeletal remains in nonmetric variant analysis using 3D models. The present study investigates the accuracy of 20 computed tomography (CT) 3D reconstruction models compared to the real crania, focusing on the quality of the reproduction of the real crania and the possibility to detect 29 dental/cranial morphological variations in 3D images. An interobserver analysis was performed to evaluate trait identification, number, position, and shape. Results demonstrate a false bone loss in 3D models in some cranial regions, specifically the maxillary and occipital bones in 85% and 20% of the samples. Additional analyses revealed several difficulties in the detection of cranial nonmetric traits in 3D models, resulting in incorrect identification in circa 70% of the traits. In particular, pitfalls included the detection of erroneous position, error in presence/absence rates, in number, and in shape. The lowest percentages of correct evaluations were found in traits localized in the lateral side of the cranium and for the infraorbital suture, mastoid foramen, and crenulation. The present study highlights important pitfalls in CT scan when compared with the real crania for nonmetric analysis. This may have crucial consequences in cases where 3D databanks are used as a source of reference population data for nonmetric traits and pathologies and during bone-CT comparisons for identification purposes.     

MI Implementation in Juvenile Justice: A Case Report

Motivational interviewing (MI) is a communication style focused on enhancing clients’ own motivation towards change. In the justice system MI has evidence to support that it enhances communication and change behaviors in youth. As most MI training is designed for healthcare settings training and implementation of MI must be adapted to fit the juvenile justice model. This includes both rehabilitation and restorative justice. Here we describe the details that allowed one county small county in Pennsylvania to roll out MI training and initial skills review in less than 6 months. The case reviews the details of planning, trainings, and timing of activities. We then discuss what elements of those details fit into a greater implementation plan that may be applied elsewhere. Four key elements were instrumental to implementation: 1) appreciation of JPO time constraints, 2) cost containment 3) using blending to enhance JPO flexibility with MI use, and 4) policies that normalize use of MI. This outline may assist other courts in their own implementation efforts.     

Does it pay to break male gender stereotypes in advertising? A comparison of advertisement effectiveness between the United Kingdom,Poland and South Africa

Advertisers shy away from using non-traditional (vs. traditional) male gender portrayals even though theory suggests they may be more effective cross-nationally. Two main hypotheses were tested cross-nationally for the first time. H1: ‘paternalistic’ male stereotypes (e.g. Househusband) would be more effective than ‘envious’ male stereotypes (e.g. Businessman) across countries confirming the stereotype content model (SCM). H2: the match between initial male gender role attitudes and advertisement type would increase advertisement effectiveness only in countries with relatively low egalitarian norms (i.e. Poland and South Africa). A cross-national study was conducted through the use of student samples following a 3(country: United Kingdom, Poland and South Africa) × 2(advertisement type) × (gender attitude) mixed design (N = 373). A three-way multivariate analysis of variance showed support for H1 and partial support for H2 (i.e. the second hypothesis held on purchase intent and for South Africa). The study provides evidence for the cross-national applicability of the SCM to advertising and the limited predictive value of gender attitudes for purchase intent depending on country. Thus, contrary to mainstream advertising practices, breaking male gender stereotypes does appear to pay cross-nationally. Theoretical and practical implications alongside the potential for change in practices are discussed.     

Instruments for Exploring Organizational Culture: A Review of the Literature

Organizational culture is widely considered to be one of the most significant factors in reforming and modernizing public administration and service delivery. This article documents the findings of a literature review of existing qualitative and quantitative instruments for the exploration of organizational culture. Seventy instruments are identified, of which 48 could be submitted to psychometric assessment. The majority of these are at a preliminary stage of development. The study's conclusion is that there is no ideal instrument for cultural exploration. The degree to which any measure is seen as "fit for purpose" depends on the particular reason for which it is to be used and the context within which it is to be applied.     

The White House as a Black Box: Oral History and the Problem of Evidence in Presidential Studies

Scholars who study the American presidency usually have to rely on indirect evidence for understanding the internal operations of the 'black box' that is a contemporaneous White House. Most of the direct evidence about White House behavior becomes available only after a president has left office, when confidential communications are opened to the public by the presidential libraries. In recent years, however, such direct evidence has become increasingly inaccessible, because of changes in the record-keeping habits of senior executive branch officials and because of the politics of archival release. This article explores the nature and extent of these problems, and how elite oral history interviewing can compensate for them. It further examines the strengths and weaknesses of oral history as a means of learning about the usually hidden workings of the American presidency.     

Last Thoughts on <Emphasis Type="Italic">The Last Intellectuals</Emphasis>

Over twenty years ago my book The Last Intellectuals put into circulation the phrase “public intellectual.” The term unexpectedly enjoyed great success. It encapsulated a new division between a professional or academic intellectual focused on his or her specialty and an intellectual orientated to a larger public. The former tend to disappear into the university, while they latter write for the educated public. In the twenty years since its publication, my book has been sharply challenged. Moreover the emergence of African-American and women intellectuals, and well as new developments such as Internet, have possibly undermined my thesis. Yet these phenomena amount to revisions, not refutations, of my thesis. Moreover the role of intellectuals in France and Germany suggest that the same process of academization is taking place in other advanced industrial nations. What is called for is not nostalgia or its opposite, a celebration of everything that happens, but a consideration of the real shifts that affect the lives and work of intellectuals.

“People the North”: Nation‐building in 1960s Australia

The People the North Committee, founded in Townsville in 1962, was true to its name. It wanted to treble the population of northern Australia in a decade. Putting people before profits, the committee insisted that Australians had a moral obligation to prolifically populate their northern lands. Neither the ambition nor the rationale was new. In fact, the People the North Committee was the last gasp of a grand demographic aspiration that went back more than a hundred years. Thereafter, through to the present day, proposals for northern development have prioritised economic over demographic gains: profits before people. This article examines the ambitions and advocacy of the People the North Committee, setting them in the longer historical trajectory of the aspiration to people the north. In doing so, it offers a window onto a neglected facet of the nation‐building project in Australia.
