Determining attribute weights using mathematical programming

Group decisions are an important element of successful knowledge management in organizations. Such decisions are difficult to make, however, especially when they involve a large set of attributes that require decision-makers to develop rankings. This paper presents a goal programming model for determining constrained regression estimates of attribute weights. The model is developed using pair-wise comparison ratings that are derived by using triads of the attributes. In addition, metrics are presented for measuring individual and group consensus. A specific application to the health care industry is presented to illustrate results that are obtained from the model.     

Successfully exiting homelessness: experiences of formerly homeless mentally ill individuals

This study aims to identify and describe processes of change enabling achievement of stable housing among homeless individuals. Twelve previously homeless individuals who had maintained stable housing for a period of at least 24 consecutive months provided information through semi-structured interviews on the following topics: (1) the personal experience of homelessness, (2) the process of becoming housed, and (3) the role of significant life relationships. Only the second and third topic areas were included in this discussion. Eight categories were developed and analyzed from the qualitative interviews, including: work/employment difficulties, substance use and/or mental illness, cyclical nature of homelessness, personal motivation, housing-related issues, lessons learned, relationships with family/friends and relationships with service providers. The participants highlighted relationships with family, friends and service providers as central in the processes of achieving stable housing.     

Spatial Risk Assessment Across Large Landscapes with Varied Land Use: Lessons from a Conservation Assessment of Military Lands

Spatial decision-support tools are necessary for assessment and management of threats to biodiversity, which in turn is necessary for biodiversity conservation. In conjunction with the U.S. Geological Survey-Biological Resources Division's Species at Risk program, we developed a GIS-based spatial decision-support tool for relative risk assessments of threats to biodiversity on the U.S. Army's White Sands Missile Range and Fort Bliss (New Mexico and Texas) due to land uses associated with military missions of the two bases. The project tested use of spatial habitat models, land-use scenarios, and species-specific impacts to produce an assessment of relative risks for use in conservation planning on the 1.2 million-hectare study region. Our procedure allows spatially explicit analyses of risks to multiple species from multiple sources by identifying a set of hazards faced by all species of interest, identifying a set of feasible management alternatives, assigning scores to each species for each hazard, and mapping the distribution of these hazard scores across the region of interest for each combination of species/management alternatives. We illustrate the procedure with examples. We demonstrate that our risk-based approach to conservation planning can provide resource managers with a useful tool for spatial assessment of threats to species of concern.     

Parenting Mediates the Effects of Income and Cumulative Risk on the Development of Effortful Control

This study tested the hypothesis that the effects of income and cumulative risk on the development of effortful control during preschool would be mediated by parenting. The study utilized a community sample of 306 children (36–40 months) representing the full range of family income, with 29 percent at or near poverty and 28 percent lower income. Two dimensions of effortful control (executive control and delay ability) were assessed at four time points, each separated by nine months, and growth trajectories were examined. Maternal warmth, negativity, limit setting, scaffolding, and responsiveness were observed. Above the effects of child cognitive ability, income, and cumulative risk, scaffolding predicted higher initial levels of executive control that remained higher across the study, and limit setting predicted greater gains in executive control. Parenting did not predict changes in delay ability. Significant indirect effects indicated that scaffolding mediated the effects of income and cumulative risk on growth in executive control. The findings suggest that parenting behaviors can promote effortful control in young children and could be targets of prevention programs in low‐income families.     

Gendered policies and practices that increase older men's risk of elder mistreatment

We aim to detail some of the ways that social policy and gendered practices put older men at risk of elder mistreatment. Research on the abuse and neglect that older adults experience has often focused on the characteristics of the victims and the dynamics within families, emphasizing factors such as the likelihood of an intergenerational cycle of violence, substance abuse and dependency, and older men's financial status as key risks in elder abuse. The effect on men from this type of analysis is that elder mistreatment remains an individual or family problem rather than being viewed as a larger societal concern. This article challenges the individualistic focus by outlining the importance of societal forces affecting older men's risk of mistreatment.     

Optimal smoothing of direct estimates of the power spectrum

In this paper we demonstrate how the task of spectral density estimation by direct methods may be posed as that of solving a simple optimal smoothing problem. A criterion functional is considered which involves a smoothness frequency domain term and a fidelity time domain term.     

New monte carlo results on the robustness of the anova f,w and f statistics

Because the usual F test for equal means is not robust to unequal variances, Brown and Forsythe (1974a) suggest replacing F with the statistics F or W which are based on the Satterthwaite and Welch adjusted degrees of freedom procedures. This paper reports practical situations where both F and W give * unsatisfactory results. In particular, both F and W may not provide adequate control over Type I errors. Moreover, for equal variances, but unequal sample sizes, W should be avoided in favor of F (or F ), but for equal sample sizes, and possibly unequal variances, W was the only satisfactory statistic. New results on power are included as well. The paper also considers the effect of using F or W only after a significant test for equal variances has been obtained, and new results on the robustness of the F test are described. It is found that even for equal sample sizes as large as 50 per treatment group, there are practical situations where the F test does not provide adequately control over the probability of a Type I error.     

Five cases illustrating the possibilities and limitations of indirect treatment of problem children 1

Most of the published literature on disability determination focuses on prevalence, applying for benefits, or sociodemographics. There is a paucity of literature that addresses the impact on treatment when a clinician is asked to contribute to a disability determination in the midst of an ongoing psychotherapy. In addition, the clinical literature is primarily written by and for psychiatrists. Yet a disability determination during psychotherapy is at the heart of clinical social work practice when it attends to the patient’s environment by offering help with material needs, while simultaneously providing relationally based treatment.
