The impact of touch-tone data entry on reports of HIV and STD risk behaviors in telephone interviews

Respondents concerns about privacy can decrease reporting of HIV and STD risk behaviors in general population telephone surveys. The purpose of this paper is to describe the results of an experimental study evaluating whether one method for increasing privacy, touch-tone data entry (TTDE), is effective in increasing estimates of sexual behaviors from a population-based survey. We conducted a random-digit-dial telephone survey of adults in New Jersey (n = 405), with half the respondents using TTDE for answering sexual behavior questions. TTDE led to increased reports of same-sex sexual behavior, certain HIV and STD risk factors, and concern about one s risk for HIV and STD transmission. TTDE also narrowed the difference between men s and women s reports of the number of different sexual partners over the past 10 years. The feasibility and limitations of TTDE are discussed, as well as possible alternative interpretations that consider the impact of TTDE on the dynamics of the interaction between the respondent and the interviewer.     

Multi-family psychoeducation groups in the treatment of children with mood disorders

This study examined the impact of adjunctive multi-family psychoeducation groups (MFPG) on mood-disordered children aged 8 to 11 and their families. Participants were 35 children and 47 parents from families randomly assigned to either immediate MFPG plus treatment as usual (n = 18) or a 6-month wait-list condition plus treatment as usual (n = 17). At the 6 month follow up, immediate treatment families reported: Increased parental knowledge about childhood mood symptoms; increased positive family interactions as reported by the parent; increased perceptions of parental support as reported by children; and increased utilization of appropriate services by families. Expected impact on decreasing negative family interactions was not found. Results are largely consistent with hypothesized findings and support the need to further investigate the adjunctive role of psychoeducation in the treatment of childhood mood disorders.     

Political and organizational barriers to satisfying low-income U. S. seniors' need for affordable rental housing with supportive services

A substantial share of the low-income older tenants who occupy U. S. government-subsidized rental housing has physical and cognitive limitations. These older tenants are often women living alone in their 70s and 80s, who need help obtaining community-based services, demand-responsive transportation, help with apartment housekeeping and maintenance, self-care assistance, and design modifications made to their dwellings. Other low-income and frail older persons who have large housing expense burdens or occupy physically deficient dwellings also need affordable rental housing with these supportive services. The unmet supportive service needs of these groups persist even as this country's major political and professional stakeholders are aware of their problems and have solutions. This paper examines five major political and organizational barriers that have restricted the availability of supportive services in affordable rental developments. It offers 12 policy recommendations.     

A quadratic lower bound for colourful simplicial depth

We show that any point in the convex hull of each of (d+1) sets of (d+1) points in ℝ ^d is contained in at least ⌊(d+2)²/4⌋ simplices with one vertex from each set.

Evaluation of Embedded Intelligent Real‐time Systems*

Over the past two decades, questions have surfaced about the effectiveness and contribution of intelligent systems to decision makers in a variety of settings. This paper focuses on the evaluation challenges associated with intelligent real‐time software systems that are embedded in larger host systems. With the proliferation of such systems in operational settings such as aerospace, medical, manufacturing, and transportation systems, increased attention to evaluations of such systems, and to resulting software safety, is warranted. This paper describes one such evaluation and proposes a set of evaluation criteria for embedded intelligent real‐time systems (EIRTS). Implications of the evaluation and the evaluation criteria are discussed.     

Improving Weight of Evidence Approaches to Chemical Evaluations

Federal and other regulatory agencies often use or claim to use a weight of evidence (WoE) approach in chemical evaluation. Their approaches to the use of WoE, however, differ significantly, rely heavily on subjective professional judgment, and merit improvement. We review uses of WoE approaches in key articles in the peer‐reviewed scientific literature, and find significant variations. We find that a hypothesis‐based WoE approach, developed by Lorenz Rhomberg et al., can provide a stronger scientific basis for chemical assessment while improving transparency and preserving the appropriate scope of professional judgment. Their approach, while still evolving, relies on the explicit specification of the hypothesized basis for using the information at hand to infer the ability of an agent to cause human health impacts or, more broadly, affect other endpoints of concern. We describe and endorse such a hypothesis‐based WoE approach to chemical evaluation.     

Portfolio Analysis of Layered Security Measures

Layered defenses are necessary for protecting the public from terrorist attacks. Designing a system of such defensive measures requires consideration of the interaction of these countermeasures. In this article, we present an analysis of a layered security system within the lower Manhattan area. It shows how portfolios of security measures can be evaluated through portfolio decision analysis. Consideration is given to the total benefits and costs of the system. Portfolio diagrams are created that help communicate alternatives among stakeholders who have differing views on the tradeoffs between security and economic activity.     

The nature,extent and determinants of violence against psychiatric personnel

Violence against psychiatric staff seems to be on the increase. Such abuse can lead to mental health consequences for the staff and a reluctance to be closely involved with patients. Few Swedish investigations have examined violence against mental nurses and psychiatrists, or undertaken comparative studies between them. In this study we examined the extent, nature and determinants (i.e. risk factors) of violence against psychiatric nurses (n = 731) and psychiatrists (n = 320) working in the eight health care districts of Stockholm. These caregivers were assessed cross-sectionally by means of a questionnaire covering various areas (e.g. violence and work environment). The majority of the participants (85%) reported having been exposed to violence during their careers, with 57% being victimized in the past 12 months. Physical violence was common, and factors such as negative attitudes to work and diminished sense of autonomy were associated with an increased vulnerability to violence. Nurses and psychiatrists did not differ in violence variables. In spite of the weaknesses of the design (cross-sectional self-selecting sample), this study corroborates previous findings and identifies personal factors associated with violence that have received little attention in the literature (e.g. lack of respect for the organization of care).
