Evaluation of a novel tagging and tissue preservation system for potential use in forensic sample collection

The authors describe a new, easy-to-use barcode-based tissue collection, preservation and body tracking system, which might prove instrumental in the containment of mass fatalities such as aircraft accidents, war related accidents, environmental disasters (e.g. earthquakes, hurricanes, and floods) terrorist bombings or mass murders.     

The past and the future of violence against women

The most important thing we have learned about violence against women over the past 20 years is that violence is gendered and learned and can only be understood in the context of gender inequality. Most violence is male, and although some violence is done by females, it is far from equal and often done for very different reasons. Among other major findings is that children from violent households tend to grow up to be problematic, which means that a major method of curbing juvenile delinquency in 10 years is to stop violence against women today.     

Social security: a program and policy history

Many of the federal and state programs that provide income security to U.S. families have their roots in the Social Security Act (the Act) of 1935. This Act provided for unemployment insurance, old-age insurance, and means-tested welfare programs. The Great Depression was clearly a catalyst for the Social Security Act of 1935, and some of its provisions--notably the means-tested programs--were intended to offer immediate relief to families. However, the old-age insurance program-the precursor to today's Old-Age, Survivors, and Disability Insurance, or Social Security, program-was not designed specifically to deal with the economic crisis of that era. Indeed, monthly benefit payments, under the original Act, were not scheduled to begin until 1942. In addition, from the beginning, the Social Security program has embodied social insurance principles that were widely discussed even before the onset of the Great Depression. The first four decades of the Social Security program were, in general, ones of expansion. In fact, the program was expanded even before it became truly operational. In 1939, amendments added child, spouse, and survivor benefits to the retirement benefits authorized by the 1935 Act. Those amendments also allowed for monthly benefits to begin in 1940. Although the program was not changed substantially during the war years and the initial postwar period, the 1950s were a transformational decade in the program's history: benefit amounts were increased substantially, coverage under the program became close to universal, and a new disability insurance benefit was offered. The 1960s witnessed additional growth in Social Security, but the most important development in social insurance occurred in health insurance, with the creation of the Medicare program in 1965. Legislative actions in the 1970s had profound effects on the Social Security program and, indeed, set the stage for many of today's reform debates. Large benefit increases, a new benefit formula that was erroneously generous, and other changes in the early 1970s created a situation in which annual program costs, as a share of gross domestic product, increased during a 12-year period from about 3 percent to 5 percent. In 1977, amendments to the Act corrected the flawed benefit formula and made other changes in the financing of the system to shore up the program. Thus, the 1970s represent a watershed in the program's history-program growth gave way to increasing concerns about the program's finances. Those concerns were reflected in the amendments to the Act in 1983, which were the last major changes to the program. These amendments, based largely on recommendations from a commission chaired by Alan Greenspan, adjusted benefits and taxes to address pressing near-term financing problems faced by the system. Although the Greenspan Commission focused to a large extent on short-range issues, the resulting reforms have generated large surpluses in the program and the buildup of a substantial trust fund. However, the looming retirement of the baby boomers and several other demographic factors will, according to projections, result in the exhaustion of the trust fund by 2042.     

“Thinking About Makin’ It”: Black Canadian Students’ Beliefs Regarding Education and Academic Achievement

Black Canadians share many aspects of the historical experiences of African Americans, but there are also important differences. One similarity between these two groups is the persistent academic underachievement of Black adolescents. Although this is a subject of widespread concern in both countries, it has received little empirical scrutiny in Canada. We address this shortcoming by examining the academic and achievement-related beliefs of Black high school students in two Canadian cities, Toronto and Halifax. Despite significant regional differences most participants believed that schooling could lead to success for them. Females’ attitudes and beliefs regarding education were more positive than those of males. Perceived parental values and support were strong predictors of participants’ attitudes and school marks; socioeconomic status (SES) and perceived peer support were non-significant correlates of academic outcomes. We discuss the results in terms of the germane US research, and highlight the implications of the findings for understanding diversity among Black Canadian youth.Received PhD from the University of Toronto. Areas of research include educational and psychological correlates of ethnic and racial identity in Black Canadians.Received PhD from the University of Toronto. Research focuses on the cultural dimensions of friendship.Received PhD from the University of Toronto. Research interests include adolescent development, social justice, and children’s rights-related thinking and knowledge.     

Neck injuries caused by automatic two-point seat belts: an analysis of four cases

Although seat belts significantly reduce the extent and severity of injuries sustained by motor vehicle occupants, seat belts are known to be associated with chest and abdominal trauma. Less commonly understood are severe neck injuries caused by the use of two-point automatic shoulder harnesses without concurrent use of a manual lap belt. Such injuries may include cervical spine fractures, craniocervical dislocations and rarely decapitation. Recognizing patterned injuries caused by seat belts and the ability to correlate autopsy findings with the circumstances surrounding the death will allow for correct interpretation of seat-belt related trauma. The four cases described detail fatal neck injuries as a result of improper seat belt use in which an automatic two-point shoulder harness was used without a manual lap restraint. In two of the cases, the victims were decapitated.     

A duplex real-time qPCR assay for the quantification of human nuclear and mitochondrial DNA in forensic samples: implications for quantifying DNA in degraded samples

A duplex real-time qPCR assay was developed for quantifying human nuclear and mitochondrial DNA in forensic samples. The nuclear portion of the assay utilized amplification of a approximately 170-190 bp target sequence that spans the repeat region of the TH01 STR locus, and the mitochondrial portion of the assay utilized amplification of a 69 bp target sequence in the ND1 region. Validation studies, performed on an ABI 7000 SDS instrument using TaqMan detection, demonstrated that both portions of the duplex assay provide suitable quantification sensitivity and precision down to 10-15 copies of each genome of interest and that neither portion shows cross-reactivity to commonly encountered non-human genomes. As part of the validation studies, a series of DNase-degraded samples were quantified using three different methods: the duplex nuclear-mitochondrial qPCR assay, the ABI Quantifiler Human DNA Quantification Kit qPCR assay, which amplifies and detects a 62 bp nuclear target sequence, and slot blot hybridization. For non-degraded and moderately degraded samples in the series, all three methods were suitably accurate for quantifying nuclear DNA to achieve successful STR amplifications to yield complete profiles using the ABI AmpFlSTR Identifiler kit. However, for highly degraded samples, the duplex qPCR assay provided better estimates of nuclear template for STR amplification than did either the commercial qPCR assay, which overestimated the quantity of STR-sized DNA fragments, leading to an increased proportion of undetected alleles at the larger STR loci, or slot blot hybridization, which underestimated the quantity of nuclear DNA, leading to an increased proportion of STR amplification artifacts due to amplification of excess template.     

In the Eye of the Storm: The Italian Economy and the Eurozone Crisis

Abstract

The eurozone crisis had a more significant and longer-lasting impact on Italy than on virtually any other member state, with the effects still visible a decade after. The extent of the shock was surprising in view of progress Italy had apparently made in the 1990s in terms of enhancing its capacity to meet the demands of European Monetary Union. The explanation for this traumatic economic experience lies in Italy’s deep, long-term, structural tensions which were placed under severe pressure during the 1990s and which were cracked open by the 2011 sovereign debt crisis. These have had long-standing economic effects as well as political ramifications in terms of a significant change in the Italy–EU relationship.
