Human dental age estimation by calculation of pulp-tooth volume ratios yielded on clinically acquired cone beam computed tomography images of monoradicular teeth

Abstract: Secondary dentine is responsible for a decrease in the volume of the dental pulp cavity with aging. The aim of this study is to evaluate a human dental age estimation method based on the ratio between the volume of the pulp and the volume of its corresponding tooth, calculated on clinically taken cone beam computed tomography (CBCT) images from monoradicular teeth. On the 3D images of 111 clinically obtained CBCT images (Scanora^®3D dental cone beam unit) of 57 female and 54 male patients ranging in age between 10 and 65 years, the pulp–tooth volume ratio of 64 incisors, 32 canines, and 15 premolars was calculated with Simplant^® Pro software. A linear regression model was fit with age as dependent variable and ratio as predictor, allowing for interactions of specific gender or tooth type. The obtained pulp–tooth volume ratios were the strongest related to age on incisors.     

History of interpersonal violence, abuse, and nonvictimization trauma and severity of psychiatric symptoms among children in outpatient psychiatric treatment

In a clinical sample of child psychiatry outpatients, chart review data were collected for 114 consecutive admissions over a 1-year period at a Child and Adolescent Outpatient Psychiatry Clinic. Data included history of documented maltreatment, potentially traumatic domestic or community violence, neglect or emotional abuse, and noninterpersonal stressors as well as demographics, psychiatric diagnoses, and parent-rated child emotional and disruptive behavior problems. On a bivariate and multivariate basis, any past exposure to interpersonal violence-but not to noninterpersonal traumas-was related to more severe disruptive behavior problems, independent of the effects of demographics and psychiatric diagnoses. Noninterpersonal trauma and psychiatric diagnoses were associated with emotional problems; exposure to interpersonal violence appeared to partially account for this relationship despite not being independently associated with emotional problem severity. History of exposure to interpersonal violence warrants clinical and research attention as a severity marker and potential treatment focus in psychiatric outpatient services for children, particularly those with disruptive behavior problems.     

The “Same,Related, or Interrelated” Acts or Claims Provision: Insurers’ Efforts to Expand the Reasonable Application of Such Provisions to Deny or Otherwise Limit Coverage under Claims-Made Policies

Claims-made insurance policies often contain provisions regarding the treatment of the same, related, or interrelated acts or claims. Such language may affect the number of policy limits and retentions available as well as the timing of when multiple claims are deemed made. This article examines sample policy language as to the same, related, or interrelated acts or claims provisions as well as the disparate case law interpreting such provisions. The result is several principles to guide policyholders in the application of such language and to counter insurers’ efforts to unreasonably use such language to limit or deny coverage.     

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.     

Perceived Sanction Threats and Projective Risk Sensitivity: Auto Theft,Carjacking, and the Channeling Effect

Although sanction threats promote fear, among committed offenders, that fear can become a resource with which to sculpt emerging crime preferences. In such cases, criminality is not deterred but channeled. We explore the channeling process here as it relates to auto theft and carjacking. Our qualitative findings reveal that auto thieves are reluctant to embrace the violence of carjacking due to concerns over sanction threat severity they attributed to carjacking—both formal (higher sentences) and informal (victim resistance and retaliation). Meanwhile, the carjackers are reticent to enact auto theft because of the more uncertain and putatively greater risk of being surprised by victims, a fear that appears to overcome the enhanced long-term formal penalty of taking a vehicle by force. We examine the implications of offenders’ decision-making for the analytic intersection of rational choice and deterrence, offering the notion of projective risk sensitivity to encapsulate the process.

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.
