Improving the standardization and efficiency of adult protective services (APS) investigations is a top priority in APS practice. Using data from the Elder Abuse Decision Support System (EADSS), we developed short-form measures of four types of elder abuse: financial, emotional/psychological, physical, and neglect. The EADSS data set contains 948 elder abuse cases (age 60+) with yes/no abuse substantiation decisions for each abuse type following a 30-day investigation. Item sensitivity/specificity analyses were conducted on long-form items with the substantiation decision for each abuse type as the criterion. Validity was further tested using receiver–operator characteristic (ROC) curve analysis, correlation with long forms and internal consistency. The four resulting short-form measures, containing 36 of the 82 original items, have validity similar to the original long forms. These short forms can be used to standardize and increase efficiency of APS investigations, and may also offer researchers new options for brief elder abuse assessments.
1. Forest wildfire impact is widely believed to increase with time since disturbance, presenting a dilemma for the persistence of fire-sensitive species. However, in south-western Australia, disturbance has been shown to increase wildfire likelihood for some decades before it again declines. It has been proposed that this trend occurs through 'ecological controls' on wildfire such as the self-thinning of fire-stimulated understorey growth.2. Here, we analyse six proposed ecological controls using a surveyed chronosequence of a Eucalyptus jacksonii forest community. We quantify plant growth (growth and self-pruning) and succession (changing plant traits, self-thinning), along with consequent changes in surface and suspended litter. We then use a biophysical, mechanistic model to predict the dynamics of flame height and canopy scorch/consumption, along with suppression difficulty during wildfire conditions.To identify the importance of each potential ecological control, we separately manipulate them to grow hypothetical forests from 1 to 100 years; each with one of the controls removed. We then model flame height in each to compare with the original forest that had all controls present. 3. Fire initially promoted dense understorey regeneration, but ecological controls transferred this biomass from fuel (likely to ignite) to overstorey shelter (unlikely to ignite, creating a less flammable microclimate). The effect of these changes was to alter modelled fire behaviour, such that flame dimensions in mature forest were half those in regrowth, canopy damage greatly reduced, and fire suppression opportunities maximised. The primary controls were self-thinning and self-pruning. Forest growth and succession explains observed trends in flammability dynamicsin south-western Australian forests, and the persistence of fire-sensitive species over time. Approaches that cooperate with, rather than disrupt, these processes therefore provide a pathway to mitigate current climatic effects on fire.
Background and Objectives Elder mistreatment victims at risk of poor physical and psychological health may benefit from increased social support. This article identifies mistreatment victims among community-dwelling older Americans and maps their social networks to guide the design of social support interventions. Research Design and Methods Using nationally representative survey data from Wave 3 (2015–2016) of the National Social Life, Health, and Aging Project (N = 2,334) and descriptive, latent class, and regression analyses, we estimate the prevalence of mistreatment since age 60, identify the alleged perpetrators’ relationships to the victims, and examine victims’ social networks. Results Self-reported lifetime prevalence of elder mistreatment is as high as 21%, depending on the mistreatment behavior measured. Latent class analysis reveals two mistreatment classes: 12% of older adults experienced multiple types of mistreatment (polyvictimization), and 6% experienced primarily financial mistreatment. Although alleged perpetrators are unlikely to appear in older adults’ core social networks, the most commonly reported perpetrators are children and relatives. Regression analyses show that experiencing mistreatment since age 60 is associated with having less current social support, more social strain, and fewer kin in the core social network. Older adults reporting polyvictimization also have less-dense core networks. Discussion and Implications Increasing family support should be done cautiously because children and relatives are frequently named as mistreatment perpetrators. Increasing communication across polyvictimization victims’ network members may support their well-being. Providing outside assistance with financial management could benefit financial mistreatment victims.
