Older workers' progression from private disability benefits to Social Security disability benefits

People with medical conditions that limit their ability to work tend to receive short-term disability benefits initially and may then move to long-term and eventually to permanent disability benefits. The progression of older workers (those aged 55 to 64) along that continuum of benefits is documented here with data from a large disability insurance company. The data show that older workers who receive short-term medical disability benefits are three times as likely as younger workers to progress to receipt of Social Security Disability Insurance (SSDI) benefits, although a slight reversal of that trend occurs as workers pass age 62. Musculoskeletal conditions are the most frequent basis of short-term disability claims among older workers, with circulatory conditions running a close second. Furthermore, although all medical conditions are more likely to lead to SSDI benefits among older workers, circulatory conditions do so most frequently. This article discusses industry standards for the management of disability claims at each level of severity. It also addresses common and emerging disability management practices that may reduce the likelihood of impaired workers developing long-term or permanent financial dependence on disability benefits programs.     

The role of the high school professional in identifying and managing adolescent suicidal behavior

The ongoing contact of adolescents with high school staff may provide an opportunity for the early identification and effective management of suicidal behavior. In this study, the knowledge, attitude, and experience of 80 high school professionals regarding adolescent suicide were assessed through semistructured personal interviews. Respondents identified more than 30 signs of potential vulnerability — manifestations of depression, verbal and written cues, isolation, and self-destructive behaviors. Among predisposing factors, those related to alienation within the family were most prominent. Other important risk factors were low self-esteem, difficulty in peer relationships, and economic or ethnic differences from other students. When suicidal behaviors occurred, respondents saw students and staff as attempting to be helpful; families were more often viewed as defensive.     

African American Oxford House residents: sources of abstinent social networks

The current study found that African American residents of Oxford House (OH) used Narcotics Anonymous (NA) at high rates, and that both OH and NA strongly contributed to abstinent social networks. Having siblings and other family members in one's network predicted substance use among network members, whereas spouses, parents, and children did not have an effect on the rate of substance use. These findings suggest that OH and NA may be effective sources of abstinent social support for African Americans recovering from substance abuse. However, family members are well represented in the support networks of African Americans in OH.     

Are savings groups a livelihoods game changer for young people in Africa?

The triad of entrepreneurship, self-employment, and financial inclusion underpins policy and development interventions meant to address the youth employment challenge in Africa. Youth savings groups are being widely promoted as a first step toward financial inclusion and economic empowerment. This article reports on the links between income-generating activities of 57 members of youth savings groups in Tanzania, Uganda, Zambia, and Ghana, and their membership in savings groups. It concludes that while savings groups can help to facilitate operational expenses and cash flow – and thus support members’ micro-enterprises – in opportunity starved contexts their transformational potential is probably being oversold.     

Economic Interests and Threat Assessment in the US Congress, 1890–1914

Why do some domestic actors see the international environment as a threatening place populated by untrustworthy powers, when others find opportunities for peaceful cooperation in the same conditions? Because these actors confront the same international environment, the reasons for their divergent evaluations must rest on differences in their own beliefs and interests. In this article, we consider the impact of societal interests in trade and trade protection on elite assessments of the international environment. We examine evaluations of the international environment in speeches given in the US Congress during naval appropriations debates between 1890 and 1914. The manufacturing sector’s interest in trade protection led political leaders who represented manufacturing regions to offer more negative assessments of the international environment, while those representing export-oriented agricultural areas of the country gave more positive evaluations. These effects were roughly comparable to those associated with party, as well as individual-level characteristics, such as having served as a military officer.     

Utilized coefficient of friction during walking: static estimates exceed measured values

This study compared utilized coefficient of friction (COF) measured during nonslip pedestrian gait to estimated utilized COF values calculated using anthropometric (i.e., leg length) and stride characteristic data (i.e., impact angle, step length). Twenty healthy adults walked at slow, medium, and fast speeds with kinematic and kinetic data recorded simultaneously. Estimated and measured impact angle varied with walking speed, with greater angles evident with faster speeds (p < 0.001 and p < 0.05, respectively). The estimated impact angle was greater than the measured impact angle (p < 0.05). Estimated and measured peak utilized COF values varied with walking speed, with higher utilized COF values evident with faster speeds (p < 0.001 and p = 0.001, respectively). Estimated utilized COF values were 86, 118, and 131% greater than measured peak utilized COF values for slow, medium, and fast speeds, respectively (p < 0.001). Higher estimated utilized COF values varied moderately with increased measured peak utilized COF values (r = 0.522; p < 0.001). These data suggest that impact angle and step length alone cannot be used to accurately assess the utilized COF on level walking surfaces.     

Forensic applications of infrared chemical imaging: multi-layered paint chips

This paper examines the potential of infrared chemical (hyperspectral) imaging as a technique for the forensic analysis of automotive paint chips in particular, and multicomponent (e.g., layered) samples in general. Improved sample preparation procedures for the infrared analysis of paint chips are detailed, with the recommendation that where mounting resins are chemically incompatible with the sample, it is better to mount and section the sample in a soft wax from which the sections can be removed and pressed into a KBr disk for transmission analysis. Infrared chemical images of multilayered paint chips have been successfully obtained, with the chief advantage over conventional infrared analysis being that thousands of infrared spectra are collected in a few minutes across the whole sample, at a spatial resolution of around 5 microm. As with conventional infrared spectroscopy, chemical species can be identified from their spectra, but the wealth of information available can be also extracted in a number of different ways that make multicomponent spectral (and hence chemical) comparisons between two samples easy to visualize and understand. In one approach, the infrared chemical images of two paint chips being compared side-by-side can be viewed as a "movie," in which each frame is an intensity map of the two samples at a given wavenumber (frequency) value. In another approach, the spectra (pixels) in the image files are classified into chemically similar groups, resulting in a "cluster" image that makes it possible to simultaneously compare all of the layers in two paint chips. These methods are applicable to other multicomponent samples, and also to other chemical imaging techniques.     

Examining the links between animal abuse and human violence

Empirical research has increasingly found evidence for the coexistence of animal abuse and various forms of interpersonal violence. Some researchers have even argued for a specific version of this relationship, namely, that individuals tend to move from violence toward animals, particularly in childhood, to subsequent violence toward humans. Others have suggested that the evidence for this graduation or progression hypothesis is weak and inconsistent, and that an approach to animal abuse that focuses on the link is misguided. This article begins by reviewing the research on the connections between animal abuse and interhuman violence. Then it critically assesses the evidence for and against the link, and discusses the issues and challenges facing future research in this area.
