Assistive technology outcomes in work settings

Successfully documenting the outcomes of assistive technology (AT) interventions in the workplace benefits people with disabilities, service providers and agencies. However, no work related system currently exists that comprehensively collects the data needed to analyze such outcomes. Part of the reason for this absence of an outcome system is that, while the concept is simple, the process is complex and depends on the acquisition of data that represent many outcomes related variables. This article describes the exploratory work of the NIDRR (National Institute on Disability and Rehabilitation Research) funded ATOMS Project (Assistive Technology Outcomes Measurement System) and its efforts to identify existing data that might be used as the basis for an outcomes measurement system. Sample records from four assistive technology service programs were acquired and evaluated for the data they housed. This study discovered that AT service programs fail to collect consistent or sufficient data for outcomes analysis. However, discussions with AT programs that provided services to State vocational rehabilitation agencies revealed an interesting potential. Assistive technology service data in combination with data collected by State vocational rehabilitation departments might coalesce the needed data. The Federal Rehabilitation Services Administration (RSA) 911 Report aggregates many variables of outcomes related information including employment status and the success of the vocational rehabilitation investment. This combined database could answer a range of assistive technology outcomes related questions of interest to service providers, people with disabilities, and vocational rehabilitation State agencies. This paper describes the data needed in an outcomes system, reviews the data that appear to be available today related to AT outcomes, and projects how data from two diverse programs might be used together to create a significant outcomes database.     

Reassessing the Insurance Effect: A Qualitative Analysis of Fertility Behavior in Senegal and Zimbabwe

A number of prominent demographers have recently reiterated the argument that a lasting mortality decline is a key determinant of the fertility transition. Of the main hypothesized pathways linking fertility to mortality, the one least studied is the insurance hypothesis: the notion that, in high‐mortality contexts, people decide to have more children in order to anticipate possible future child deaths and lessen the risks of having too few surviving offspring. In‐depth interviews and focus groups from Zimbabwe and Senegal are used to examine this hypothesis and to extend it into a broader theory of reproductive decision making under uncertainty. Whereas insurance strategies are frequent in Zimbabwe and occur in urban Senegal, in the higher‐mortality settings—the rural Senegalese site and the recent past described by respondents in Zimbabwe and urban Senegal—deliberate fertility‐limitation strategies are rare. The data depict fundamental changes in attitudes, strategies, and behaviors concerning family size over time and, in Senegal, over space. Important reproductive goals and risks extend far beyond numbers of children and mortality. Parents seek to have healthy, successful children for many reasons including companionship, descendants, and old‐age support. Diverse investments in child quality (their education, health, etc.) and quantity (numbers of births) are the main means to attain these goals and, less recognized by demographers, are also important ways for parents to manage uncertainty in family‐building outcomes; the “classic” insurance mechanism is only one, often minor, aspect of the quantity option.     

An Examination of Cross‐Racial Comparability of Mother‐Child Interaction Among African American and Anglo American Families

This study examined the cross‐racial comparability of maternal quality of assistance and supportive presence coded from a video protocol using data from the Infant Health and Development Program for low‐birth‐weight, premature 30‐month‐olds and their mothers. Evidence of equivalence of measures is necessary before comparisons can be made across groups. Multiple‐group mean and covariance structures analysis was used to demonstrate the invariance of the measures and make comparisons for Anglo American and African American treatment and comparison groups of dyads. Comparisons across groups indicated similar variances and correlation between child and maternal behavior. Differences were found between the mean scores, with Anglo American treatment families scoring the highest.     

A Half Century of Mate Preferences: The Cultural Evolution of Values

The qualities people believe are important in selecting a marriage partner afford one domain for assessing human values. We examined the cultural evolution of these values over more than half a century. Building on existing data on mate preferences collected in 1939 (N= 628 ), 1956 (N= 120 ), 1967 (N= 566 ), and 1977 (N= 316 ), we collected data using the same instrument in 1984/1985 (N= 1,496 ) and in 1996 (N= 607 ) at geographically diverse locations. Several changes in values were documented across the 57‐year span. Both sexes increased the importance they attach to physical attractiveness in a mate. Both sexes, but especially men, increased the importance they attach to mates with good financial prospects. Domestic skills in a partner plummeted in importance for men. Mutual attraction and love climbed in importance for both sexes. The sexes converged in the ordering of the importance of different mate qualities, showing maximum similarity in 1996. Discussion speculates about causes of the cultural evolution of values.     

Fitting models for the joint action of two drugs using SAS

Combinations of drugs are increasingly being used for a wide variety of diseases and conditions. A pre-clinical study may allow the investigation of the response at a large number of dose combinations. In determining the response to a drug combination, interest may lie in seeking evidence of 'synergism', in which the joint action is greater than the actions of the individual drugs, or of 'antagonism', in which it is less. Two well-known response surface models representing no interaction are Loewe additivity and Bliss independence, and Loewe or Bliss synergism or antagonism is defined relative to these. We illustrate an approach to fitting these models for the case in which the marginal single drug dose-response relationships are represented by four-parameter logistic curves with common upper and lower limits, and where the response variable is normally distributed with a common variance about the dose-response curve. When the dose-response curves are not parallel, the relative potency of the two drugs varies according to the magnitude of the desired effect and the models for Loewe additivity and synergism/antagonism cannot be explicitly expressed. We present an iterative approach to fitting these models without the assumption of parallel dose-response curves. A goodness-of-fit test based on residuals is also described. Implementation using the SAS NLIN procedure is illustrated using data from a pre-clinical study.     

A Meta-Analytic Review of the Association Between Disgust and Prejudice Toward Gay Men

ABSTRACT

A sizeable number of studies have documented a relationship between heterosexual persons’ experience of disgust (measured as an individual difference variable or induced experimentally) and prejudice toward gay men (i.e., homonegativity). Yet, to date, no one has attempted to meta-analytically review this corpus of research. We address this gap by conducting a meta-analysis of published and unpublished work examining heterosexual men and women’s disgust and their homonegativity toward gay men. Fourteen articles (12 published, two unpublished) containing 17 studies were analyzed (N = 7,322). The average effect size for disgust sensitivity studies was moderate to large (d = 0.64), whereas for disgust induction studies, the effect was large (d = 0.77). No evidence of effect size heterogeneity emerged. Future directions and recommendations for methodological improvements are outlined.     

Evaluation of free to grow: head start partnerships to promote substance-free communities

Free to Grow: Head Start Partnerships to Promote Substance-free Communities (FTG) was a national initiative in which local Head Start (HS) agencies, in partnership with other community organizations, implemented a mix of evidence-based family-strengthening and community-strengthening strategies. The evaluation of FTG used a quasi-experimental design to compare 14 communities that participated in the FTG intervention with 14 matched comparison communities. Telephone surveys were conducted with two cohorts of the primary caregivers of children in HS at baseline and then annually for 2 years. The survey was also administered to repeated cross-sectional samples of primary caregivers of young children who were not enrolled in HS. No consistent evidence was found in changes in family functioning or neighborhood conditions when the 14 FTG sites were compared to 14 matched sites. However, caregivers of young children who were not in HS in three high-implementing FTG sites showed evidence of improvements in neighborhood organization, neighborhood norms against substance abuse, and child disciplinary practices. Results provide highly limited support for the concept that family and neighborhood conditions that are likely to affect child development and well-being can be changed through organized efforts implemented by local HS programs.     

Antisociality and intimate partner violence: the facilitating role of shame

Numerous theories classify distinct subtypes of men who perpetrate violence against female partners. These theories contend that a large portion of these men possess antisocial characteristics that may increase risk for violence. Affectively, these men have been found to externalize their emotions, including shame and guilt, and it has been suggested that this process contributes to the perpetration of partner violence. Therefore, this study sought to examine the role of shame and guilt in the association between antisociality and partner violence perpetration (i.e., psychological, physical, and sexual). Based on a sample of 423 undergraduate men, this study found that shame moderated the association between antisociality and partner violence perpetration such that as shame increases, the associations between antisociality and all three types of partner violence perpetration increase. These findings contribute to the theoretical understanding of typological models of partner violence and have clinical implications for batterer intervention programs.     

More Powerful Forces? Women,Nonviolence, and Mobilization

In this survey of studies of women's nonviolent mobilization, I scrutinize “more powerful forces,” the mobilizing forces of marginalized social actors that add to and make possible the development of broad‐based people power. The study of people power has yet to extensively consider the contribution of marginalized social actors. Specifically, I ask: (i) What do women contribute to the development of nonviolent protest power and (ii) What can we learn about mobilizing power, the power of people to protest nonviolently and gain the franchise they seek, when we expand our analytical lens to incorporate women's roles? How do we account for the gendered but often unseen actions taken by marginalized social actors? My focus on women in nonviolent mobilization stems directly from my research on gendered invisibility with an empirical focus on women's gendered socialization. Here, I review how gendered social structures shape women's power of participation and success in nonviolent mobilization.
