Age and gender differences and predictors of victimization of the older homeless

Using data from the National Survey of Homeless Assistance Providers and Clients (NSHAPC) and an application of Felson's Routine Activities Theory, this paper examines gender and age differences in victimization experiences of a sample of more than 4,200 homeless and near-homeless people, mostly adults. Results suggest that there are no differences in victimization experience by homelessness status and that the negative relationship between age and victimization rates found in the general population is also found in the homeless population. However, the relationship is relatively weak and erratic, suggesting that homeless older adults who are at least 50 years old are at increased risk of becoming victims, a finding consistent with Routine Activities Theory. In addition, similar to research with other populations, younger homeless males are statistically more likely to report being victims of theft and physical assault while females of all ages are more likely to report being victims of sexual assault. However, for older homeless adults, the gender difference in likelihood of victimization disappears. Perhaps because older homeless women are labeled as easy targets, they were equally as likely as men to be victims of physical assault and theft in old age. This is also consistent with Routine Activities Theory.     

Weighing the success of a national Alzheimer's disease service demonstration

As the need for long-term care services within the United States has grown dramatically, Congress has consistently deflected the primary responsibility for such care to state governments, local organizations, and, ultimately, the family. This paper examines the impact of the Alzheimer's Disease Demonstration Grants to States (ADDGS) program, a small federally funded initiative within the context of this trend. Although the demonstration can be deemed a huge success relative to the goals of creating new services for an underserved target population, questions are raised about the merits of the program relative to the exploding need for an effective network of long-term care services.     

Single-cell antisense RNA amplification and microarray analysis as a tool for studying neurological degeneration and restoration

Neurodegenerative diseases typically affect subpopulations of neurons. Characterizing these vulnerable cells and identifying the factors that make them susceptible to damage while neighboring cells remain resistant are essential to the understanding of molecular pathogenesis that underlies neurodegenerative diseases. Classically, molecular analysis of the central nervous system involves the identification and isolation of an anatomic region of interest; next, the relevant tissue is pulverized, and the resulting homogenate is analyzed. Although this method provides useful data, its effectiveness diminishes when used in areas of high cellular diversity or in instances in which one cell type is lost as a consequence of selective cell death or quiescence. A technique that affords the ability to assess molecular events in a very precise anatomical site would provide a powerful tool for this research discipline. In this review, we discuss the amplification of messenger RNA from single neural cells and the subsequent use of the RNA to probe DNA microarrays in an effort to create cell-specific molecular profiles. Specifically, recent work in single-cell expression profiling in Alzheimer's and Huntington's diseases is discussed. We also review some new work with neural stem cells and their application to restorative neurobiology. Finally, we discuss the use of cell-specific molecular profiles to better understand the basics of neuronal cell biology.     

Acceptance of Global Positioning System (GPS) Technology Among Dementia Clients and Family Caregivers

The purpose of this study was to examine the acceptance of Global Positioning System (GPS) used to help people with dementia, who are at risk for wandering in their communities. We used a mixed methods research approach that included use logs, pre and post paper-based questionnaires, and focus groups. Forty-five client-caregiver pairs (dyads) were included to use one of the GPS devices for an average of 5.8 months over a 1-year period. GPS acceptance was high; dyads were likely to continue using the GPS. According to the participants, the GPS provided caregivers peace of mind and reduced anxiety in dyads when clients got lost.     

A Comparison of Actual and Perceived Sexual Risk Among Older Adults

Sexual risk among older adults (OAs) is prevalent, though little is known about the accuracy of sexual risk perceptions. Thus, the aim was to determine the accuracy of sexual risk perceptions among OAs by examining concordance between self-reported sexual risk behaviors and perceived risk. Data on OAs aged 50 to 92 were collected via Amazon.com’s Mechanical Turk. Frequency of sexual risk behaviors (past six months) were reported along with perceived risk, namely, sexually transmitted infection (STI) susceptibility. Accuracy categories (accurate, underestimated, overestimated) were established based on dis/concordance between risk levels (low, moderate, high) and perceived risk (not susceptible, somewhat susceptible, very susceptible). Approximately half of the sample reported engaging in vaginal (49%) and/or oral sex (43%) without a condom in the past six months. However, approximately two-thirds of the sample indicated they were “not susceptible” to STIs. No relationship was found between risk behaviors and risk perceptions, and approximately half (48.1%) of OAs in the sample underestimated their risk. Accuracy was found to decrease as sexual risk level increased, with 93.1% of high-risk OAs underestimating their risk. Several sexual risk behaviors are prevalent among OAs, particularly men. However, perception of risk is often inaccurate and warrants attention.     

Kooperative Resilienz – ein soziotechnischer Ansatz durch Kooperationstechnologien im KrisenmanagementCooperative resilience – a sociotechnical approach through cooperation technologies in crisis management

Whilst the concept of resilience in engineering is mainly focussed on the availability of technical systems, we rather see resilience as socio-technical construct and show opportunities to encourage cooperative resilience with the help of cooperation technologies. After a general definition of resilience in our application field of emergency management and in the context of cooperative structures, we present our methodology and the developed cooperation technologies. They address the collaboration of diverse players (such as police, fire department, and citizen) in major emergencies. Finally we discuss the input of this technology for cooperative resilience to overcome crises of cooperation with the help of adaptability to modified realities by means of cooperation technology.     

Parent–child negative emotion reciprocity and children's school success: An emotion‐attention process model

Research has demonstrated that emotions expressed in parent–child relationships are associated with children's school success. Yet the types of emotional expressions, and the mechanisms by which emotional expressions are linked with children's success in school, are unclear. In the present article, we focused on negative emotion reciprocity in parent–child interactions. Using structural equation modeling of data from 138 parent to child dyads [children's mean age at Time 1 (T1) was 13.44 years, SD = 1.16], we tested children's negative emotionality (CNE) at T1 and low attention focusing (LAF) at Time 2 (T2) as sequential mediators in the relation between parent and child negative emotion reciprocity at T1 and children's grade point average (GPA) and inhibitory control at T2. Our findings supported an emotion‐attention process model: parent–child negative emotion reciprocity at T1 predicted CNE at T1, which predicted children's LAF at T2, which was, in turn, related to low inhibitory control at T2. Findings regarding children's GPA were less conclusive but did suggest an overall association of negative reciprocity and the two mediators with children's GPA. Our findings are discussed in terms of emotion regulation processes in children from negatively reciprocating dyads, and the effects of these processes on children's ability to obtain and use skills needed for success in school.
