Multimodal urgency coding: auditory, visual, and tactile parameters and their impact on perceived urgency

Through a series of investigations involving different levels of contextual fidelity we developed scales of perceived urgency for several dimensions of the auditory, visual, and tactile modalities. Psychophysical ratings of perceived urgency, annoyance, and acceptability as well as behavioral responses to signals in each modality were obtained and analyzed using Steven's Power Law to allow comparison across modalities. Obtained results and their implications for use as in-vehicle alerts and warnings are discussed.     

HIV seroprevalence and risk behaviors among clients attending a clinic for the homeless in Miami/Dade County,Florida, 1990–1996

In the early 1990s, HIV seroprevalence was highest at the Miami homeless clinic among 16 homeless sites participating in a nationwide sentinel survey. To examine dynamic seroprevalence patterns in Miami's homeless clients in relation to demographics and risk behaviors over six years, we analyzed data from an unlinked (blinded) serosurvey of clients attending the principal primary care clinic serving Miami's homeless. Data were from 3,797 medical encounters with homeless persons who, on their initial clinic visit within an annual survey period, received routine serologic testing and a risk behavior survey. Overall HIV seroprevalence was 15.9% and infection rates for men (16.4%) and women (14.5%) did not differ. Seroprevalence for blacks (19.9%) was significantly higher than for Hispanics (9.1%) or whites (8.3%) (p < 0.0001). Seroprevalence was 12.6% (35 times the national rate) for clients reporting heterosexual contact as their only risk. Significant increases in seroprevalence, above this heterosexual-contact-only 'baseline', were found for clients disclosing high-risk behaviors: male-to-male sex, drug injection, receiving or giving money/drugs for sex, and sexual contact with a drug injector or HIV-infected partner (p < 0.0001). Seroprevalence declined over six years from 23.2 to 7.2% (p < 0.0001). Significant downward trends were observed for men and women, blacks and Hispanics, men who have sex with men, and clients reporting heterosexual contact. The proportion of clients reporting high-risk behaviors decreased sharply (p < 0.0001). Elevated HIV seroprevalence in Miami's homeless clients was strongly associated with high-risk behaviors. Expansion of HIV prevention and HIV/drug treatment services for homeless persons is strongly recommended.     

Understanding Chinese-Canadian pathways to a diagnosis of dementia through a critical-constructionist lens

Efforts to understand pathways to a diagnosis of Alzheimer's Disease and Related Dementias (ADRD) are important in light of the benefits of early diagnosis to both patients and families, but very little is known about the ways in which persons with dementia and their family caregivers experience this pathway from the point of initial symptom recognition by family or friends to formal diagnosis seeking, particularly for immigrant older adults. Our team employed qualitative methods and a critical constructionist and intersectional framework to understand this experience from the perspectives of ten Chinese-Canadian dyads of persons with dementia and their caregivers. Situating the decisions made by these dyads relative to their intersecting identities and the power structures that inhibit them steered us away from essentializing attributions of their experiences to their ‘culture’ or ethnicity. Early signs of dementia were recognized as such in hindsight. There was no evidence of a strong link between culture and symptom appraisal. Knowledge about dementia, which may be influenced by culture, age, income, knowledge of English, and other determinants of health, played a role in symptom appraisal and help seeking. The role of family caregivers in care-seeking was more highly influenced by structural factors than by traditional Chinese cultural norms about family responsibilities and filial piety. Once caregivers realized that the symptoms and behaviors were ‘problematic,’ they quickly sought out additional information, usually from a family physician. At 1.5 years, the time between symptom onset and diagnosis is comparable to or shorter than that reported in research with other cultural groups. Gender-based power imbalance between female family caregivers and male Chinese-Canadian physicians appear to have contributed to delayed investigations and diagnosis. Sensitivity to such imbalances is important when working with older adults and those from more hierarchical cultures. Essentialized portraits of traditional family structures and cultural beliefs may not accurately reflect the variety of lived experiences of the dementia care-seeking by older Chinese immigrants in Canada.     

Understanding the Lives of Mothers after Incarceration: Moving Beyond Socially Constructed Definitions of Motherhood

In the wake of mass incarceration, an increasing number of women are going through the penal system. A fair number of these women are mothers, yet the intersection of motherhood and prison may contradict conceptions of femininity and challenge traditional views of appropriate mothering. The contradiction between notions of criminality and femininity contributes to stigmatized perceptions of formerly incarcerated mothers, which drastically shapes their ability to reintegrate into society post‐incarceration. While reentry efforts tackle gender differences through the implementation of gender‐responsive programs that cater to women's needs, failure to adequately account for unique maternal experiences may hinder attempts to address obstacles faced by mothers in particular, such as regaining child custody and paying for day care. This article argues for special attention to the post‐incarceration experiences of mothers without imposing socially constructed definitions of motherhood like having custody and living with children, which may not coincide with the realities mothers face after imprisonment. Ideas are also discussed for the inclusive consideration of formerly incarcerated mothers and their post‐incarceration experiences.     

The magnitude and potential impact of missing data in a sexual violence campus climate survey

Abstract

Objective: Assess the impact of survey non-response and non-completion for a campus climate survey. Participants: Intended for all degree-seeking students at a large, public, midwestern university, November 2014. Methods: The survey covered sexual assault experiences and related attitudes. We identify the magnitude and potential impact of survey non-response by comparing demographic data between respondents and non-respondents, sexual assault prevalence between early and late respondents, and demographic and attitudinal data between survey completers and partial completers. Results: Demographic groups were differentially represented in the survey. Sexual assault prevalence based on survey results may be underestimated for men, overestimated for women. Sensitive questions did not increase drop-off. Students completing more of the survey differed from those completing less. Conclusions: Colleges must plan survey administration and data sensitivity analysis to reduce potential for bias. Resources for sexual assault-related needs based on estimates from campus climate surveys with high non-response will likely be misallocated.     

The Dangers of Assessing the Financial Vulnerability of Nonprofits Using Traditional Measures

This article analyzes the financial vulnerability of 228 British nongovernmental development organizations (NGDOs) during the period 2008–2012. To do this, we use the Financial Vulnerability Index developed by Trussel et al. (2002). This index is commonly used in the literature on nonprofit organizations. However, we observe a very poor adaptation of the index to the reality of this industry, at least in predictive terms. The article goes deeply into each of the variables that are used to calculate this index, and we offer explanations of their inadequacy to this subsector of nonprofits.     

Moral Reasoning in Interactional Context: Strategic Uses of Care and Justice Arguments in Mediation Hearings*

Previous studies of moral reasoning have treated moral reasoning as a product of the individual. This article extends the study of moral reasoning by analyzing its use in strategic interaction. I analyze how participants in a naturally occurring situation of conflict use moral arguments strategically and negotiate over the types of arguments that are acceptable. Gilligan's Care and Justice modes of moral reasoning are identified in participants' justifications for positions taken in nine videotaped mediation hearings. I found that participants may use both modes of reasoning during the course of a hearing, and that the type of moral argument used is often a response to the actions of other participants. Strategic uses of moral arguments included shifting mode to challenge or support another's position, bridging a difference in mode between two disputants, and shifting mode to refocus the topic. Because of their institutional and interactional roles in the hearings, mediators play a major role in negotiations over mode of moral reasoning.     

Interorganizational collaboration in social service organizations: A study of the prerequisites to success

Organizational scholars have identified four prerequisites to effective interorganizational collaboration: incentive, willingness, ability, and capacity. This study analyzes data drawn from participants in eight family services collaboratives in order to assess the relationships identified in the literature. Our findings support the premise that each of these prerequisites is positively related to collaborative effectiveness. Implications for collaboration leaders are suggested.     

Are the Effects of Monetary Policy Asymmetric?

By building on the Hamilton (1989) Markov switching model, we examine questions like: Does monetary policy have the same effect in expansions and recessions? Given that the economy is currently in a recession, does a fall in interest rates increase the probability of an expansion? Does monetary policy have an incremental effect on the growth rate within a given state, or does it only affect the economy if it is sufficiently strong to induce a state change (e.g., from recession to expansion)? As suggested by models with sticky prices or finance constraints, interest rate changes have larger effects during recessions.
