The use of the M-Vac® wet-vacuum system as a method for DNA recovery

Collecting sufficient template DNA from a crime scene sample is often challenging, especially with low quantity samples such as touch DNA (tDNA). Traditional DNA collection methods such as double swabbing have limitations, in particular when used on certain substrates which can be found at crime scenes, thus a better collection method is advantageous. Here, the effectiveness of the M-Vac® Wet-Vacuum System is evaluated as a method for DNA recovery on tiles and bricks. It was found that the M-Vac® recovered 75% more DNA than double swabbing on bricks. However, double swabbing collected significantly more DNA than the M-Vac® on tiles. Additionally, it was found that cell-free DNA is lost in the filtration step of M-Vac® collection. In terms of peak height and number of true alleles detected, no significant difference was found between the DNA profiles obtained through M-Vac® collection versus double swabbing of tDNA depositions from 12 volunteers on bricks. The results demonstrate that the M-Vac® has potential for DNA collection from porous surfaces such as bricks, but that alterations to the filter apparatus would be beneficial to increase the amount of genetic material collected for subsequent DNA profiling. These results are anticipated to be a starting point to validate the M-Vac® as a DNA collection device, providing an alternative method when DNA is present on a difficult substrate, or if traditional DNA collection methods have failed.     

Trends in Mortality of the Soviet Population

Two prominent American demographers present an up-to-date study of trends and countertrends in mortality of the Soviet population; discussed are variations (by republic and over time) in life expectancy, infant mortality, and mortality in the working ages. Analyzing trends since 1959, the authors highlight problems relating to the quality and interpretation of pertinent statistical data of Soviet origin. Distinguishing real trends from pseudotrends, they evaluate mortality differences among regions and illustrate a more favorable long-term trend in mortality than suggested by official figures (nonetheless, because of error in official statistics, actual rates are generally higher).

From ethnocide to ethnoviolence: Layers of native American victimization

The contemporary phenomenon of ethnoviolence - otherwise known as hate crime - has its roots deeply embedded in the historical persecution of Native Americans by representatives of 'the state and private individuals alike. Genocidal policies and practices of the past have their present counterparts in anti-activist and anti-treaty violence, as well as in isolated acts of violence against individual Native Americans. This paper traces the threads that bind together the (d)evolution from ethnocide to ethnoviolence.     

Partner similarity for self-reported antisocial behaviour among married,cohabiting and dating couples: the Generation R Study

Abstract

From a criminological perspective, romantic relationships are supposed to decrease the risk of antisocial behaviour (Laub, Nagin, & Sampson, American Sociological Review, 63, 225–238, 1998). However, the effects of these relationships probably depend on the romantic partner's behaviour. In the current study we examined partner similarity for antisocial behaviour in an ethnically heterogeneous community sample of 4135 married, cohabiting and dating couples from Rotterdam, the Netherlands, using self-reports. Spousal correlations were consistently positive for antisocial behaviour but differed in strength according to the type of antisocial behaviour. Associations between spouses remained strong after adjusting for age and educational level depending on the type of antisocial behaviour. In addition, antisocial behaviour was positively associated between partners across marital status and ethnicity, but the strength of this association varied to some extent. Results are discussed in light of the phenotypic assortment, the socialization and the social homogamy hypotheses.     

Defining A Product Market for Spanish-Language Broadcast Media: Lessons from United States v. Univision Communications,Inc. and Hispanic Broadcasting

In 2003, a media merger with dramatic content and policy implications went largely unnoticed. Little attention was paid to the transaction because it did not affect the majority; it affected the largest minority population in the United States: Hispanics. Although up to 65% of Hispanics prefer Spanish-language media, most broadcast media now come from one corporation, Univision. In approving the consolidation of Univision and Hispanic Broadcasting, the FCC ignored product market findings by the Department of Justice as well as its own policy precedent, which includes numerous exceptions for Spanish programming to promote content and ownership diversity. Consistent with the FCC's mandate to protect the public interest, a demand-side analysis is undertaken, positioning the audience as consumer. Industry evidence, product market thresholds, and ownership rules are applied to United States v. Univision, Inc. and Hispanic Broadcasting, with the conclusion that a separate product market must exist for Spanish language broadcast media.     

Mapping an agenda for the study of youth sexual aggression in Europe: assessment,principles of good practice,and the multilevel analysis of risk factors

ABSTRACT

Sexual aggression is a serious threat to young people's sexual health in Europe, but establishing the exact scale of the problem has been hampered by a variety of conceptual and methodological problems. This article presents a framework for studying youth sexual aggression that addresses both prevalence and risk factors of victimisation and perpetration. It proposes a research tool to comprehensively assess the perpetration of, and victimisation by, sexual aggression that captures different coercive strategies, sexual acts, victim–perpetrator relations, and gender constellations. The instrument is rooted in a clear conceptual definition of sexual aggression and was pilot-tested in 10 countries of the European Union (EU). Furthermore, a list of good practice criteria is proposed to promote the quality and comparability of research on youth sexual aggression in Europe. A multilevel approach combining individual-level and country-level predictors of sexual aggression is outlined and illustrated with data from the pilot study in 10 countries.     

Working on the Ground. A Collective Biography of Feminine Subjectivities: Mapping the Traces of Power and Knowledge

In this paper we map the traces of power and knowledge as we read them at play in our own memories and as we make sense of them from a Foucauldian perspective. Our question here is twofold: how might we use Foucault to read our embodied memories of power and knowledge; and how might we use the analysis of those stories to enable us better to see the implications of Foucault's writing for the analysis of subjects' enmeshment in power/knowledge relations? We use as the ground of our analysis our own embodied memories of achieving ourselves as appropriate(d) subjects (as girls and women, in relation to men--fathers, lovers, and husbands). Our trajectory in this paper is double. First, it has been towards uncovering the ways in which girls and women might be said to be powerful, even when they are complicit in their own subjection. Second, it has been to show that when Foucault defines all acts of power to involve the possibility of resistance and freedom, and he takes the opposite, a state of domination, to arise from 'economic, political, or military means', he has not fully acknowledged the extent to which the repeated, minute accretions of everyday practices can generate sedimentations of lines of force that may also be understood as a state of domination.     

The reverse mortgage as an asset management tool

Abstract

Reverse mortgages are usually seen as a vehicle for increasing the income of poor, elderly households. This perspective, coupled with the relatively slow growth of reverse mortgage programs, has led some observers to question the growth potential of the reverse mortgage market. This article presents a more expansive view of reverse mortgages as a financial tool for tapping housing equity for various purposes and at various stages in the life cycle.

Three market segments for reverse mortgages are discussed: elderly persons living alone, other elderly households, and non‐elderly households. Potential uses include turning housing equity into personal human capital investment accounts, enabling children to provide care for their disabled parents, funding elderly households’ long‐term care insurance, and sustaining consumption. Recent progress in product development and availability and political pressures to find private financing for health and long‐term care suggest that the reverse mortgage market has considerable growth potential.     

The contributions of historic preservation to housing and economic development

Abstract

Historic preservation contributes greatly to housing and economic development. Historic preservation has produced almost 250,000 housing units through use of the federal historic rehabilitation tax credit. Additionally, heritage tourism is a multibillion‐dollar industry, and preservation projects help further community revitalization.

Historic preservation also has a downside. Preservation's growing popularity may dilute its imperative and market prowess, and some argue it is used to thwart new development. Preservation requirements may impede affordable housing production and displace area residents. These undesirable consequences are not givens, however. Preservationists are working to become more flexible, and we suggest ways to practice historic preservation while mitigating some of its negative consequences—for example, tax credit changes, more flexible building codes, and a “tiered” system of designating historic properties at varying levels of significance.
