Patella sex determination by 3D statistical shape models and nonlinear classifiers

Sex determination is one of the essential steps in personal identification of an individual from skeletal remains. Most elements of the skeleton have been subjected to discriminant function analysis for sex estimation, but little work has been done in terms of the patella. This paper proposes a new sex determination method from the patella using a novel automated feature extraction technique. A dataset of 228 patellae (95 females and 133 males) was amassed from the William M. Bass Donated Skeletal Collection from the University of Tennessee and was subjected to noninvasive high resolution computed tomography (CT). After the CT data were segmented, a set of features was automatically extracted, normalized, and ranked. The segmentation process with surface smoothing minimizes the noise from enthesophytes and ultimately allows our methods to distinguish variations in patellar morphology. These features include geometric features, moments, principal axes, and principal components. A feature vector of dimension 45 for each subject was then constructed. A set of statistical and supervised neural network classification methods were used to classify the sex of the patellar feature vectors. Nonlinear classifiers such as neural networks have been used in previous research to analyze several medical diagnosis problems, including quantitative tissue characterization and automated chromosome classification. In this paper, different classification methods were compared. Classification success ranged from 83.77% average classification rate using labels from a Fuzzy C-Means (FCM) clustering step, to 90.3% for linear discriminant classification (LDC). We obtained results of 96.02% and 93.51% training and testing classification rates, respectively, using feed-forward backpropagation neural networks (NN). These promising results using newly developed features and the application of nonlinear classifiers encourage the usage of these methods in forensic anthropology for identifying the sex of an individual from incomplete skeletons retaining at least one patella.     

DETECHIP®: A Sensor for Drugs of Abuse*

Abstract: The design and preliminary characterization of a novel sensor for drugs of abuse, DETECHIP^®, is described in this proof‐of‐concept note. Combining both colorimetric and fluorimetric assays, DETECHIP^® is suitable for lab and field use. More than a conventional spot test which provides a single “yes or no” answer, DETECHIP^® provides twenty responses for a more complete characterization of suspect material. This is accomplished by visually noting colorimetric and fluorescent changes of carefully selected dyes upon the addition of test analytes, including drugs of abuse, with respect to controls. Color and fluorescence changes are recorded numerically so that a 20 digit identification code can be constructed for comparison of test analytes and known compounds. DETECHIP^® is applicable to a variety of drugs, both plant‐derived and synthetic, addressing the need to use several different spot tests simultaneously for a single sample.

Self-deception and other-deception among admissions to a maximum security hospital and a medium secure unit

Abstract

Other-deception and self-deception are important variables to consider when conducting a forensic psychological evaluation. The main aim of the present study was to investigate the effects of setting on other-deception and self-deception scores. It was hypothesised that patients at a maximum security hospital (Broadmoor) would score lower on an other-deception questionnaire than similar patients at a medium secure unit (Denis Hill Unit). All the patients completed the other-deception (ODQ) and self-deception (SDQ) questionnaires of Sackeim and Gur (1979) on admission to the two security hospitals. The Broadmoor patients (N = 46) obtained significantly lower ODQ score than the Denis Hill Unit (N = 52) patients, after controlling for differences in ethnic background and diagnosis among the two populations. No significant difference in setting was found for the SDQ score. The ODQ and SDQ scores were significantly associated with the type of diagnosis and the ethnic background of the patient, with patients diagnosed as mentally ill scoring higher than those with a diagnosis of personality disorder, and ethnic minority patients scoring higher than Caucasian patients.     

Getting The Right Mix: Unpacking Integration Meanings and Strategies

Integration has emerged as having an increasingly significant role in public policy discourse and practice in many jurisdictions across the globe. In providing a different framework for establishing relationships between service providers and citizens and government, horizontal integration arrangements offer the prospect of delivering new ways of working and providing solutions to seemingly insolvable social problems. Ways of achieving horizontal integration have been variously described by linkage terms such as cooperation, coordination, and collaboration. These terms have been typically used interchangeably to describe the coming together of individuals to work in concerted effort to achieve common goals.We argue that each of these terms, expressed as the “3Cs,” are different and consequently achieve different objectives. This paper explores the use of the “3Cs” and examines the differences highlighted by practitioners in the human services arena to extend the understanding of constructs relating to integration mechanisms. It is contended that in focusing on the experiences of integration and unpacking the use and expectations of the related “3Cs,” public administrators and practitioners will gain an enhanced understanding of each of the processes of integration as a coherent framework. As a consequence, there will be improved ability to match appropriate integration mechanisms with contexts and strategies.     

Institutionalised Co-production: Unorthodox Public Service Delivery in Challenging Environments

In developing countries in particular, services are often delivered through unorthodox organisational arrangements that cannot simply be dismissed as relics of ‘traditional’ institutions, or as incomplete modern organisations. Some have emerged recently, and represent institutional adaptations to specific political and logistical circumstances. We need to expand the range of organisational categories that are considered worthy of study and develop a better understanding of the strengths and weaknesses of unorthodox arrangements. The concept of institutionalised co-production provides a useful point of entry. Institutionalised co-production is defined as: the provision of public services (broadly defined, to include regulation) through a regular long-term relationship between state agencies and organised groups of citizens, where both make substantial resource contributions. We explain some varieties of institutionalised co-production arrangements; explore why they appear to be relatively so widespread in poor countries; and relate the concept to broader ideas about public organisation.
