Education and Poverty: Confronting the Evidence

Current U.S. policy initiatives to improve the U.S. education system, including No Child Left Behind, test‐based evaluation of teachers, and the promotion of competition are misguided because they either deny or set to the side a basic body of evidence documenting that students from disadvantaged households on average perform less well in school than those from more advantaged families. Because these policy initiatives do not directly address the educational challenges experienced by disadvantaged students, they have contributed little—and are not likely to contribute much in the future—to raising overall student achievement or to reducing achievement and educational attainment gaps between advantaged and disadvantaged students. Moreover, such policies have the potential to do serious harm. Addressing the educational challenges faced by children from disadvantaged families will require a broader and bolder approach to education policy than the recent efforts to reform schools.     

Working together to cut numbers in the criminal justice system

Here at the Centre for Crime and Justice Studies, we are not strictly speaking a campaigning organisation. However, we are interested in forming a coalition with academics, practitioners, our members and all those for whom the current rate of imprisonment and the government's concerted lack of commitment to the significant reduction of prison numbers, is of grave and ongoing concern; it is unacceptable.     

Stable carbon and nitrogen isotope ratios of sodium and potassium cyanide as a forensic signature

Sodium and potassium cyanide are highly toxic, produced in large amounts by the chemical industry, and linked to numerous high-profile crimes. The U.S. Centers for Disease Control and Prevention has identified cyanide as one of the most probable agents to be used in a chemical terrorism event. We investigated whether stable C and N isotopic content of sodium and potassium cyanide could serve as a forensic signature for sample matching, using a collection of 65 cyanide samples. Upon analysis, a few of the cyanide samples displayed nonhomogeneous isotopic content associated with degradation to a carbonate salt and loss of hydrogen cyanide. Most samples had highly reproducible isotope content. Of the 65 cyanide samples, >95% could be properly matched based on C and N isotope ratios, with a false match rate <3%. These results suggest that stable C and N isotope ratios are a useful forensic signature for matching cyanide samples.     

Social relationships between prisoners in a maximum security prison: Violence, faith, and the declining nature of trust

Purpose

This paper describes significant changes to social relationships in a high security prison, including the prominent role played by faith identities and fears of radicalisation in shaping prisoner social life.

Methods

The study consists of a repeated sociological investigation of the nature of staff-prisoner relationships at a single site in the UK. Methods included extensive observation, the creation of a regular dialogue group with 14 prisoners, long, private interviews with 32 staff and 52 prisoners, focus groups, and surveys with 170 prisoners and 180 staff.

Results

The study found a decline in already low levels of trust, with dramatic effects on the prison's inner life. Relationships between prisoners were fractured, more deeply hidden than in the original study, and the traditional prison hierarchy, formerly easily visible in long-term prisons, had dissolved. Longer sentences, fears of radicalisation, confusion about prison officer power, and high rates of conversion to Islam, reshaped the dynamics of prison life, raising levels of fear. Clear indications of the anxieties and social unravellings of late modern society were found.

Conclusions

Increased punitiveness, indeterminate sentences, the intensification of risk-oriented practices, and anxieties relating to terrorism, have deepened the tone and reshaped the practices of long-term imprisonment.     

Chemical enhancement of soil based footwear impressions on fabric

This study investigates the enhancement of footwear impressions prepared with soils from different locations on a variety of fabric surfaces with different morphology. Preliminary experiments using seventeen techniques were carried out and the best responding reagents were evaluated further. Results indicated that the soils investigated (a cross-section of soils from Scotland) are more likely to respond to reagents that target iron ions rather than calcium, aluminium or phosphorus ions. Furthermore, the concentration of iron and soil pH did not appear to have an effect on the performance of the enhancement techniques. For the techniques tested, colour enhancement was observed on all light coloured substrates while enhancement on dark coloured fabrics, denim and leatherette was limited due to poor contrast with the background. Of the chemical enhancement reagents tested, 2,2'-dipyridil was a suitable replacement for the more common enhancement technique using potassium thiocyanate. The main advantages are the use of less toxic and flammable solvents and improved clarity and sharpness of the enhanced impression. The surface morphology of the fabrics did not have a significant effect on the enhancement ability of the reagents apart from a slight tendency for diffusion to occur on less porous fabrics such as polyester and nylon/lycra blends.     

The role of law in public health preparedness: opportunities and challenges

We report the results of a study designed to assess and evaluate how the law shapes the public health system's preparedness activities. Based on 144 qualitative interviews conducted in nine states, we used a model that compared the objective legal environment with how practitioners perceived the laws. Most local public health and emergency management professionals relied on what they perceived the legal environment to be rather than on an adequate understanding of the objective legal requirements. Major reasons for the gap include the lack of legal training for local practitioners and the difficulty of obtaining clarification and consistent legal advice regarding public health preparedness. Narrowing the gap would most likely improve preparedness outcomes. We conclude that there are serious deficiencies in legal preparedness that can undermine effective responses to public health emergencies. Correcting the lack of legal knowledge, coupled with eliminating delays in resolving legal issues and questions during public health emergencies, could have measurable consequences on reducing morbidity and mortality.     

Adult violence with the mother and sibling as predictors of partner violence

The present study provides the first available evaluation of how violence with the mother and siblings during adulthood is associated with the occurrence of partner violence in young adults. Because a pattern of reciprocal partner violence is well documented, the authors hypothesized that reciprocal violence would also be found for adults and their mothers and for adults and their siblings. The authors also hypothesized that reciprocal violence with the mother and sisters would explain variance in partner violence even when controlling for other known predictors (poverty, poor family support, stress, anger, low self-esteem). Study participants included 377 college adults (114 men, 263 women; mean age = 24.4 years) who completed questionnaires to report their present violence to and from their mothers, sisters, brothers, and romantic partners. Violence is measured with a modified Conflict Tactics Scale. No sibling gender differences are found in violence reported as adults. Factor analysis confirms good fit for three clusters of reciprocal violence for adults: violence with the mother, violence with siblings, violence with the romantic partner. Violence with the mother and siblings significantly explains variance in partner violence even after controlling for other contextual variables, but only for women. One interpretation of present results is that because women receive less socialization than men to use violence, these two within-family models of violence have more significance for increasing their risk of partner violence. Partner violence prevention programs could include participation of mothers and siblings to enhance development of more peaceful conflict resolution patterns within and outside the family.
