Aboriginal Glass Artefacts of the Sydney Region

Aboriginal glass artefacts (AGAs) have become the ‘type fossil’ for recognizing post-contact sites in countries with colonial pasts. Whether such reliance on AGAs is a valid development is contentious as the identification of these artefacts is ambiguous. This uncertainty is amplified in densely populated urban environments such as Sydney. This thesis addresses the identification of these artefacts within this region. Technological characteristics of Sydney’s AGAs and methodological issues in the recording of these artefacts have been analysed. A review of the patterns within this data has revealed how the identification issue has been managed in the past and how it may be improved. A review and evaluation of previous ‘criteria for identification’ has also revealed a refined approach to the identification and categorization of AGAs within Sydney and beyond. Also, cross-cultural interactions have been characterized as affected by the unique and diverse nature of the moving frontier in this region

A community-based survey of posttraumatic stress disorder in the Netherlands

In this study, the lifetime prevalence of stressful events and current posttraumatic stress disorder (PTSD) in the general adult population in theNetherlands were examined, and risk groups for PTSD were determined. A representative sample of 2,238 adults (≥18 years) in the Netherlands completed digital questionnaires by computer-assisted self-interviewing. In total, 52.2% of the population reported at least one stressful event throughout their life. The estimated prevalence of current PTSD in the total population was 3.8%. Rape and physical assault were the stressful events most likely to be associated with PTSD, witness of injury the least likely. Stressful medical events were moderately associated with PTSD. Prevalence of PTSD was elevated among single women and middle-aged men

Waterbeelden : een studie naar de beelden van waternatuur onder medewerkers van Rijkswaterstaat

Het onderzoek bestaat uit vier delen: een schets van beelden van water in de Nederlandse cultuur en mogelijke veranderingen daarin; een literatuurstudie, uitmondend in een synthese, naar kennis over natuurbeelden, waar waternatuurbeelden afgeleiden van zijn; een inhoudsanalyse van documenten van Rijkswaterstaat, waarin uiteenlopende beelden van waternatuur bleken te overheersen; een gestructureerde vragenlijst onder medewerkers van Rijkswaterstaat. De gevonden waternatuurbeelden zijn het wilde, spontane, ruime, beonvloede en menselijke beeld
