Anthropological Facial Approximation in Three Dimensions (AFA3D): Computer‐Assisted Estimation of the Facial Morphology Using Geometric Morphometrics

This study presents Anthropological Facial Approximation in Three Dimensions (AFA3D), a new computerized method for estimating face shape based on computed tomography (CT) scans of 500 French individuals. Facial soft tissue depths are estimated based on age, sex, corpulence, and craniometrics, and projected using reference planes to obtain the global facial appearance. Position and shape of the eyes, nose, mouth, and ears are inferred from cranial landmarks through geometric morphometrics. The 100 estimated cutaneous landmarks are then used to warp a generic face to the target facial approximation. A validation by re‐sampling on a subsample demonstrated an average accuracy of c. 4 mm for the overall face. The resulting approximation is an objective probable facial shape, but is also synthetic (i.e., without texture), and therefore needs to be enhanced artistically prior to its use in forensic cases. AFA3D, integrated in the TIVMI software, is available freely for further testing.     

A classification framework for out-of-home advertising media in South Africa

Abstract

Out-of-home (OOH) advertising media have expanded worldwide and the shape and format of these media globally, as well as in South Africa, have changed considerably. Until recently, the OOH advertising media landscape consisted primarily of outdoor advertising or billboards reaching vehicular traffic, but now has expanded to include a wide range of OOH advertising media types which aim to reach a mobile audience wherever they live, work, play, drive, shop or commute. Currently there is no coherent contemporary framework to compare and select the most effective media options to reach a selected target market in a specific OOH audience environment. This article draws from academic and practitioner sources to propose a classification framework for OOH advertising media in South Africa comprising four major platforms: outdoor advertising, transit media advertising, street-and-retail furniture advertising, and digital and ambient OOH media channels. The framework serves to inform marketers of viable and cost-effective traditional and contemporary OOH advertising media options. It also indicates what platforms are appropriate to reach specific audiences effectively in a variety of environments outside their homes. This is the first framework of its kind for the South African context that offers an orderly, integrated basis for future research.     

Analysing political ideas and political action

Abstract

This paper examines the relevance of Boltanski and Thévenot's newly translated book, On justification, to the analysis of political ideas and political action. While situating the work of the authors within its initial intellectual context, namely the ‘economics of conventions’, it shows that one of the key contributions of the ‘sociology of justification’ lies in the answers it brings to two fundamental, as yet unresolved, questions in political science and political sociology: first, how is it possible to identify those ideas which are politically relevant? Second, how is it possible to capture the dynamics of public ideas? After outlining the sources of the quandaries faced within political science and political sociology as regards these two questions, the conceptual framework of Boltanski and Thévenot is presented and explained, and research perspectives suggested. This article argues that On justification provides a highly engaging, stimulating and empirically useful contribution to current debates in social and political theory around the dynamics of political arguments and ideas.     

Measuring the Frequency Occurrence of Handwriting and Handprinting Characteristics,

The premise of this study was to take a valid population sampling of handwriting and handprinting and assess how many times each of the predetermined characteristic is found in the samples. Approximately 1500 handwriting specimens were collected from across the United States and pared to obtain a representative sample of the U.S. adult population according to selected demographics based on age, sex, ethnicity, handedness, education level, and location of lower‐grade school education. This study has been able to support a quantitative assessment of extrinsic and intrinsic effects in handwriting and handprinting for the six subgroups. Additional results include analyses of the interdependence of characteristics. This study found that 98.55% of handprinted characteristics and 97.39% of cursive characteristics had an independence correlation of under 0.2. The conclusions support use of the product rule in general, but with noted caveats. Finally, this study provides frequency occurrence proportions for 776 handwriting and handprinting characteristics.     

No iceberg in sight: on the absence of WTO disputes challenging fossil fuel subsidies

The empirical record of dispute settlement cases under World Trade Organization (WTO) rules on energy subsidies consists only of cases against renewable energy (RE) subsidies, whereas WTO members have not challenged others’ much larger and environmentally harmful fossil fuel subsidies. Yet, the WTO agreement on subsidies and countervailing measures would at first sight seem to create possibilities to forestall environmentally harmful subsidization. In this article, we assess possible explanations for the skewed distribution of energy subsidies dispute settlement complaints at the WTO. We argue that differences in legally relevant characteristics of fossil fuel subsidies, on the one hand, and RE subsidies, on the other hand, largely explain this observation. In the case of RE subsidies, in particular, the disputes filed to date have targeted a much narrower set of measures than the whole range of RE subsidies currently in place, namely those incorporating a local content requirement component. Although this finding is not new, we have probed into this question more systematically, both by widening the scope of the empirical analysis from actual to potential WTO disputes on energy-related policies the European Union and the USA might have initiated, and by systematically assessing the plausibility of alternative explanations.     

Ink dating,part I: Statistical distribution of selected ageing parameters in a ballpoint inks reference population

The development of ink dating methods requires an important amount of work in order to be reliably applicable in practice. Major tasks include the definition of ageing parameters to monitor ink ageing. An adequate parameter should ideally fulfil the following criteria: it should evolve as a function of time in a monotonic way, be measurable in a majority of ink entries, be as accurate and reproducible as possible, and finally it should not be influenced too much by transfer and storage conditions. This work aimed at evaluating the potential of seven ageing parameters for ink dating purposes: the phenoxyethanol quantity, relative peak areas (RPA), three solvent loss ratios (R%, R%*, NR%) and two solvent loss parameters (R_NORM, NR_NORM). These were calculated over approximately one year for 25 inks selected from a large database to represent different ageing behaviours. Ink entries were analysed using liquid extraction followed by GC/MS analysis. Results showed that natural ageing parameters (NR% and NR_NORM) were not suitable ageing parameters for ink entries older than a few weeks. RPA used other compounds present in ink formulations in combination to PE in order to normalise the results. However, it presented particular difficulties as they could not be defined for all inks and were thus applicable only for 64% of the studied inks. Finally, the PE quantity, R% and R_NORM allowed to follow the ageing of the selected inks over the whole time frame and were identified as the most promising. These were thus selected to test three different interpretation models in the second part of this article. The possibilities and limitations of ink dating methods will be discussed in a legal perspective.     

Sondage auprès des fonctionnaires fédéraux : Synthèse des contributions canadiennes à la recherche

For about twenty years, Public Administration scholars have used the data from the Public Service Employee Survey (PSES) for their research. Two studies evaluated the uses of data, measurement models and internal validity of the U.S. government’s Federal Employee Viewpoint Survey (FEVS), and none on the use of PSES data. The article reviews studies that used Canadian PSES data to promote social science research and seeks to stimulate discussion of PSES's future and opportunities for strategic human resources research in Canada.
