Interactive hazards education program for youth in a low ses community : a quasi-experimental pilot study
A pilot study of an interactive hazards education program was carried out in Canberra(Australia), with direct input from youth participants. Effects were evaluated in relation to youthsâ interest in disasters, motivation to prepare, risk awareness, knowledge indicators, perceived preparedness levels, planning and practice for emergencies, and fear and anxiety indicators. Parents also provided ratings, including of actual home-based preparedness activities. Using a single group pretest-posttest with benchmarking design, a sample of 20 youths and their parents from a low SES community participated. Findings indicated beneficial changes on a number of indicators. Preparedness indicators increased significantly from pre- to posttest on both youth (p 0.05) or to reduce between pre- and posttest (hazards-specific fears, worry, and distress, ps ranged fromp < 0.05 to < 0.001). In terms of predictors of preparedness, a number of variables were found to predict posttest preparedness levels, including information searching done by participants between education sessions. These pilot findings are the first to reflect quasi-experimental outcomes for a youth hazards education program carried out in a setting other than a school that focused on a sample of youth from a low SES community
Skin autofluorescence, a non-invasive marker of advanced glycation end products: clinical relevance and limitations.
Advanced glycation end products (AGEs) are protein-bound compounds derived from glycaemic and oxidative stress that contain fluorescent properties, which can be non-invasively measured as skin autofluorescence (SAF) by the AGE Reader. SAF has been demonstrated to be a biomarker of cumulative skin AGEs and potentially may be a better predictor for the development of chronic complications and mortality in diabetes than glycated haemoglobin A1c. However, there are several confounding factors that should be assessed prior to its broader application: these include presence of other fluorescent compounds in the skin that might be measured (eg, fluorophores), skin pigmentation and use of skin creams. The aim of this article is to provide a theoretical background of this newly developed method, evaluate its clinical relevance and discuss the potential confounding factors that need further analysis
Linking serial sexual offences: Moving towards an ecologically valid test of the principles of crime linkage
Purpose
To conduct a test of the principles underpinning crime linkage (behavioural consistency and distinctiveness) with a sample more closely reflecting the volume and nature of sexual crimes with which practitioners work, and to assess whether solved series are characterized by greater behavioural similarity than unsolved series.
Method
A sample of 3,364 sexual crimes (including 668 series) was collated from five countries. For the first time, the sample included solved and unsolved but linkedâbyâDNA sexual offence series, as well as solved oneâoff offences. All possible crime pairings in the data set were created, and the degree of similarity in crime scene behaviour shared by the crimes in each pair was quantified using Jaccard's coefficient. The ability to distinguish sameâoffender and differentâoffender pairs using similarity in crime scene behaviour was assessed using Receiver Operating Characteristic analysis. The relative amount of behavioural similarity and distinctiveness seen in solved and unsolved crime pairs was assessed.
Results
An Area Under the Curve of .86 was found, which represents an excellent level of discrimination accuracy. This decreased to .85 when using a data set that contained oneâoff offences, and both oneâoff offences and unsolved crime series. Discrimination accuracy also decreased when using a sample composed solely of unsolved but linkedâbyâDNA series (AUC = .79).
Conclusions
Crime linkage is practised by police forces globally, and its use in legal proceedings requires demonstration that its underlying principles are reliable. Support was found for its two underpinning principles with a more ecologically valid sample
