Strengths,Limitations, and Recommendations for Instrumental Color Measurement in Forensic Soil Characterization

Color determination of soil evidence is often done by visual comparison to soil color charts. A handheld spectrophotometer was tested with representative materials for its suitability for forensic soil characterization. Instrumental colorimetry provides accurate colorimetry with ~10-fold better precision than a soil color chart. The minimum sample size for accurate color determination was between 0.02 and 0.04 mg of fine soil for the specific instrument tested. Reporting colors in the L*a*b* space permits quantification of ΔE₀₀, a measure of perceptible color difference, could enable objective quantification of small color differences and thresholds for forensic soil comparisons. A ΔE₀₀ greater than ~ 3.5 to 6 likely indicates disparate soil sources in a forensic comparison, in the absence of confounding factors like sample alteration. Despite the superior precision of instrumental colorimetry, this approach is inappropriate for samples which are mottled at an inseparable scale, attached to a substrate, or too small for instrumental measurement.     

Beyond borders: the Egyptian 1947 epidemic as a regional and international crisis

This article examines the post-Second World War regionalization and internationalization of public health by focusing on the 1947 cholera epidemic in Egypt. We argue, first, that for the Egyptian medical profession, the epidemic served as an opportunity for both anti-colonial critique and soul-searching and self-criticism: it attested to the poor medical condition of the Egyptian countryside and the work required to ameliorate it. Second, we place the Egyptian epidemic in its regional context. We show how travel restrictions affected the mobility of people and merchandise between Egypt and its neighbours, as newly formed borders were solidified, crossed or transgressed. At the same time, the epidemic served as an opportunity for Arab solidarity. Finally, the since epidemic erupted during the short term of the WHO’s Interim Commission, Egypt served as the WHO’s first testing ground, helping to prove its capability to mobilize medical assistance, disseminate medical alerts and negotiate the abolition of quarantine restrictions. The epidemic, moreover, erupted against the background of renegotiation of international sanitary conventions, which historically placed cholera and the Muslim pilgrimage to the Hejaz at their centre. The source of the epidemic in a British military base and Egypt’s ability to contain the epidemic resonated with on-going debates over international travel restriction, international health policies and local sovereignty. The 1947 cholera epidemic was thus, a defining moment in the emerging relationship between international organizations and the decolonizing world.     

In the matter of the appellation of origin for 'JAFFA'

The validity of a registration of an appellation of origin isnot impaired by the licensed use of the designation as a trademark in non-Lisbon Agreement countries, where the fruits grownare similar in quality to those produced in the appellationof origin country.     

Fear of Gang Crime: A Look at Three Theoretical Models

Gang crime and resulting public fear became a major policy focus during the 1990s, yet few studies specifically focus on fear of gang crime. Guided by social disorganization theory, we test three theoretical models about the individual thought processes leading to fear of gang crime. Using structural equation models, we find that each of these three theories—diversity, disorder, and community concern—is an important predictor of gang-related fear. In addition, we find that the indirect relationships between demographic characteristics, theoretical variables, and fear depend upon which model is tested.     

The differential predictive validity of the Youth Level of Service/Case Management Inventory: the role of gender

Most criminogenic risk assessments are developed and empirically validated on samples of boys or samples comprised of mostly boys, and subsequently applied to girls. Using a sample of male (n = 1,267) and female (n = 453) probationers, the purpose of the current study was to examine the potentially differential performance of the Youth Level of Service/Case Management Inventory (YLS/CMI) and the instrument’s eight domains for female juvenile offenders. Findings revealed gender differences in the predictive validity of the YLS/CMI in which girls scored significantly higher on the risk assessment, but recidivated at significantly lower rates than boys two years following the administration of the assessment. The predictive validity of the instrument was impacted by these gender differences in which the YLS/CMI total score was a better predictor of recidivism for boys (area under the curve (AUC) = .623) than girls (AUC = .565). The only subscales that significantly predicted recidivism for girls were the family (AUC = .607) and personality (AUC = .572) domains, whereas all of the subscales significantly predicted recidivism for boys. Directions for future research as well as gender-responsive assessment, programming, and policy implications are discussed.
