“Forced Adoption” in the Australian Story of National Regret and Apology*

This essay places the long‐standing campaign for redress and apology of women separated from their children through adoption in an historical and political context, tracing the rise of the single mother as a political voice through the Council for the Single Mother and her Child and the emergence of birth mother advocacy groups. The political actions of these mothers must be seen alongside the two national apologies already delivered and the political activism which led to them. Activism for apologies for past wrongs ought be understood in terms of the contemporary Australian politics of apology in which, in the words of Hannah Arendt, “pity is elevated to the level of a political principle”. However, in the case of these mothers, the Australian story of national regret and apology is complicated by issues of gender and sexuality. The women, unlike the Stolen Generations, child migrants and institutionalised children, do not easily or readily fit within the terms of national apology as formulated in the apologies of 2008 and 2009 which were addressed primarily to wronged and innocent children. If and when an apology is addressed to these women, its terms will necessarily differ from the earlier apologies.     

Adsorption saturation and chromatographic distortion effects on passive headspace sampling with activated charcoal in fire debris analysis

Distortion of the chromatographic profile obtained for hydrocarbons that have been sampled by adsorption onto activated charcoal is a well-known phenomenon. The work reported here helps to better define the causes of chromatographic profile distortion and offers a potential method to avoid chromatographic distortion in some cases through a subsampling technique. The recovery of hydrocarbons from an equimolar mixture was investigated to determine the influence of hydrocarbon concentration on the molar ratios of recovered components. In a one-quart container, hydrocarbon volumes as small as 24 microL (liquid) were sufficient to saturate the surface area available for adsorption on a 99.0 mm2 square of activated charcoal, resulting in significant distortions in the molar ratio and the chromatographic profile of the recovered hydrocarbons. Passive headspace sampling of a similarly small volume of unweathered gasoline spiked onto carpet padding resulted in a significant distortion of the chromatographic profile. The chromatographic profile of the recovered hydrocarbons closely resembled 75% weathered gasoline. Heating the container spiked with unweathered gasoline to evenly distribute the components and then removing a subsample of the carpet padding to a second container for passive headspace analysis greatly reduced the amount of distortion in the resulting chromatogram.     

The experience of sexual assault: findings from a statewide victim needs assessment

A statewide assessment was conducted of assaults, experiences, needs, and recommendations of 125 adult victims receiving care at 19 sexual assault centers (SACs) in the State of Maryland. More than one half of the victims (55.6%) waited years before disclosing, with delays in reporting especially likely if the assault was perpetrated by a family member (the most frequent perpetrators at 42.4% of respondents). About one half of the victims (51.3%) had been previously sexually assaulted, yet only 9% of these victims had sought treatment. The majority of respondents (69.4%) indicated they would not be filing charges against perpetrators, and of those who did, 46.2% reported dissatisfaction with the interview with police. Psychological symptoms such as depression and anxiety were the most common reasons for seeking care at the centers. Nearly all of respondents rated the care they received at the centers as very good or excellent. Respondents recommended more SACs, better advertising of their services, more mental health care within them (especially group therapy), and improved laws and law enforcement of perpetrators.     

The application of miniplex primer sets in the analysis of degraded DNA from human skeletal remains

A new set of multiplexed PCR primers has been applied to the analysis of human skeletal remains to determine their efficacy in analyzing degraded DNA. These primer sets, known as Miniplexes, produce shorter amplicons (50-280 base pairs (bp)) than standard short tandem repeat (STR) kits, but still utilize the 13 CODIS STR loci, providing results that are searchable on national DNA databases. In this study, a set of 31 different human remains were exposed to a variety of environmental conditions, extracted, and amplified with commercial and Miniplex DNA typing kits. The amplification efficiency of the Miniplex sets was then compared with the Promega PowerPlex 16 system. Sixty-four percent of the samples generated full profiles when amplified with the Miniplexes, while only 16% of the samples generated full profiles with the Powerplex 16 kit. Complete profiles were obtained for 11 of the 12 Miniplex loci with amplicon sizes less than 200 bp. These data suggest smaller PCR amplicons may provide a useful alternative to mitochondrial DNA for anthropological and forensic analysis of degraded DNA from human skeletal remains.     

Grassroots support organisations in Peru

Private developmental organisations have emerged rapidly and forcefully in Peru, amid a turbulent national context of change and acute social and economic instability over the last two decades. While no official statistics exist on the number of such organisations (there is no single entity that oversees or registers their activity), independent studies and surveys indicate that almost 350 groups, of diverse objectives and coverage, are currently operating throughout the country. The forces and influences that have shaped this sector are complex, and this article does not attempt to address each individually. Rather, it focuses on those deemed most relevant: the factors that have left their mark on the sector of private development institutions as a whole.     

Riots without killings

From 1980 to 1985 serious clashes between police and squatter activists and their supporters occurred on the streets of Amsterdam. This paper describes the series of riots that took place and analyzes five of them in greater detail. Specifically, the investigation focuses on the issue of learning from recurrent crises. Did the authorities learn from one riot to the next? If so, in what ways and at what levels? And how effective did the lessons drawn prove to be — given the fact that the other party may have learned as well. Analyzing the key decisions that have been taken in these cases and confronting them with alternative scenarios that may have been pursued, suggests that learning from crises is a two-edged sword. Its potential benefits must be traded off against risks of overgeneralization or misapplication of lessons. The paper is commented on by Arthur H.W. Docters van Leeuwen, Head of the Dutch Security Service.
