The utility of polyester and cotton as swabbing substrates for the removal of cellular material from surfaces

Various types of cotton and polyester fabrics were tested to ascertain the optimal physical and chemical characteristics of fabrics needed for the removal of cellular material from surfaces. DNA quantitation values obtained on dried saliva stains showed no difference between cotton and polyester across all constructions and solvent conditions. Fabrics used dry and with water yielded higher quantitation values than those used with isopropanol. Quantitation values were also higher for wovens and nonwovens than knits across all solvent conditions. Low thread count fabrics used with water yielded higher quantitation values, but no correlation between thread count and quantitation values was observed with dry fabrics. A low thread count woven fabric, however, outperformed other tested fabrics when swabbing object surfaces in a highly used room. Full DNA profiles from fingerprints on glass surfaces were obtained with low thread count woven and nonwoven fabrics but not with the knit fabric tested.     

Choice, Responsibility and Equality

Should responsibility for disadvantage constitute a matter of fundamental concern for egalitarians? An important strand of contemporary egalitarian thought – a strand that Elizabeth Anderson calls 'luck equality'– argues that responsibility for disadvantage should constitute a decisive concern for any acceptable egalitarian theory. Luck equality therefore requires a defensible account of responsibility; and disagreements regarding the nature and extent of responsibility for disadvantage have become central in the egalitarian literature. Anderson argues that luck equality's focus on responsibility reflects a misunderstanding of the point of equality. If persuasive, her argument would establish that egalitarian thought may do without a defensible account of responsibility. Although she fails to establish this claim, she does argue persuasively that luck equality employs the notion of responsibility overly strenuously. Her critique suggests that egalitarians must qualify their acceptance of the precept that 'genuine choice excuses otherwise unacceptable inequalities'.     

Powerful perpetrators,hidden in plain sight: an international analysis of organisational child sexual abuse cases

ABSTRACT

There is virtually no literature on child sexual abuse committed by “powerful perpetrators”, who, use position, reputation, wealth and/or power, to become influential members of their organisation. Seventeen cases relating to youth serving organisations were identified using a comprehensive search of databases covering case reviews from England, Australia and the US. A Quantitative Content Analysis was used to analyse the sample with a focus on identifying offenders’ “modus operandi”. Findings revealed a number of critical differences between powerful perpetrators and other child sexual offenders described in the literature. Findings are discussed in relation to their implications for creating safer youth serving organisations. In particular, focusing on educating YSOs to recognise and address risks posed by powerful perpetrators; expanding organisational safety policies and practices and taking steps to develop a strong, positive organisational safety culture are commended as key approaches.     

Assessing child-safe culture and practices in organisational settings: a validation and refinement of Kaufman's Organisational Safety Climate Survey

ABSTRACT

Using an Australian sample of employees (n?=?1068) we assessed the psychometric properties of Kaufman’s Organisational Safety Climate Survey and its practical utility for measuring child-safe culture within organisations. The 60-item survey was found to have adequate psychometric properties. Initial factor analyses indicated a unidimensional factor structure, despite the survey being originally conceptualised into four subscales. Cronbach’s α coefficients were .95 for the full survey, with subscales ranging from .65–.94. However, qualitative feedback from respondents indicated that the survey was somewhat laborious and repetitive, with some item ambiguity noted. Refinements to the survey resulted in a 24-item short-form survey. The psychometric properties of the short-form survey were re-assessed. Factor analyses indicated a three-factor solution. Despite a significant reduction in items, internal consistency of the scale was not compromised; reliability of subscales also improved. Validation of this short-form survey as an alternative, time-efficient measure to maximise employee participation and contribution, is recommended.     

The impact of disrupted caregiving for juvenile sexual offenders

ABSTRACT

Research that attempts to understand why young people commit sex crimes points to an array of family factors that may uniquely contribute to sexual offending over general juvenile delinquency. This study examines the potentially moderating role of disrupted caregiving in the relationship between offending and caregiver-child relationship quality. Two distinct moderators were tested: gender of caregiver and biological relationship between caregiver and child. Results indicate that juvenile sexual offenders have particularly poor relationships with their primary caregivers compared to incarcerated non-sexual offenders and community controls. Furthermore, sexual offenders with male caregivers were found to have lower relationship quality scores than sexual offenders with female caregivers. In contrast, sexual offenders raised by non-biological caregivers reported better relationship quality than did offenders raised by their biological parents. These findings suggest opportunities for early intervention, before caregiving is disrupted.
