A Comparative Study of Children and Adult Homicide Rates in the USA and the Major Western Countries 1974–1999: Grounds for Concern?

The aim of this study is to examine the changing patterns of child homicide in the USA and the other 9 major Western countries between 1974 and 1999. On the basis of standardized WHO mortality data, 5-year mean rates of Baby (<1 year), Infant (1–4), Child (5–14), and General Population Rates for Homicide (GPRH) were analyzed for 1974–78 and 1995–99 for the USA and major Western countries. The analysis provided ratios of change for children's homicide between 1974 and 1999 and ratio of ratios between adult' and children's homicide. Over the period USA male Baby homicide rose by 78% and Females 44% with a combined rise in All Children [0–14] homicides of 45%, within the context of a declining adult GPRH. In the 1970s, 3 major Western countries had either higher or similar children's homicide rates to the USA, but by the late 1990s none did. Moreover, between 1974 and 1999, the USA had the biggest rise in Baby (<1) and All Children's deaths, and only France had substantial increases, whereas Baby homicide rates fell significantly in 6 other countries. The findings indicate a worrying deterioration in U.S. child homicides. Possible links with child abuse and explanations for the results are briefly discussed. Urgent case-specific research is required to determine the cause/s for and how to reverse the worsening child homicide situation in the USA.     

Genetic structure among 38 populations from the United States based on 11 U.S. core Y chromosome STRs

A DNA database consisting of the 11 Y chromosome short-tandem-repeat (Y-STR) recommended by the Scientific Working Group on DNA Analysis Methods is constructed for 2517 individuals from 38 populations in the United States. The population samples derive from five ethnic groups currently living in 10 states. A multidimensional scaling (MDS) plot places the populations into four discrete clusters (African Americans (AA), European Americans (EA), Hispanic Americans (HA), and Asian Americans (SA)) and one dispersed cluster of Native Americans. An analysis of molecular variance (AMOVA) indicates that a large proportion of the total genetic variance is partitioned among ethnic groups (24.8%), whereas only a small amount (1.5%) is found among-populations within ethnic groups. Separate AMOVA analyses within each ethnic group show that only the NA sample contains statistically significant among-population variation. Pair wise population differentiation tests do uncover heterogeneity among EA and among HA populations; however, this is due to only a single sample within each group. The analyses support the creation of AA, EA, HA, and Asian American databases in which samples from different geographic regions within the United States are pooled. We recommend that separate databases be constructed for different NA groups.     

The evidential value of distorted and rectified digital images in footwear imprint examination

The procedure for forensic photography requires that the film plane be parallel to the taken image. Another procedure must be used when the print is located on reflecting surfaces such as vehicles, or faint marks on porous surfaces. Examination was made of the evidential value of footprint images received from the scene or taken deliberately at an angle out of proper perspective (i.e., the lens axis is not perpendicular to the target plane). An artificial target was prepared and photographed from several lens axis angles ranging from 10 degrees to 85 degrees to the perpendicular, and then rectified using the Adobe Photoshop Version 7.0. It was found that at angles less than 40 degrees , the shape and location of all the individual characteristics were similar enough in comparison to the original image. In images taken at higher angles, the original image could not be adequately restored. The full potential of this image, therefore, could not be achieved after rectification. The results of this study show that the images of a footprint taken at an angle less than 40 degrees , preserve the evidential value of the unique characteristics.     

Heart embolization with the Kirschner wire without cardiac tamponade

The case of the heart embolization with the Kirschner wire that was used for shoulder trauma fixation, 2 years previously in a 67-year-old female, is reported. This case is unique; although embolization of foreign bodies to the heart is not a novel occurrence, heart embolization with non-broken Kirschner wire with a total length of 13.5 cm without cardiac tamponade was not described in medical literature so far.     

Differences in self-report measures by adolescent sex offender risk group

Differences in self-reports among three groups of juvenile sex offenders (N = 162) were examined. Risk was defined as the sum of the following static variables based on interviews with juveniles and others and from written records: type of offense (violent or predatory = 1, not = 0), prior sex offense (any = 1, none = 0), history of sexual abuse (self or family = 1, none = 0), history of substance abuse (self or family = 1, none = 0), history of behavior problems (yes = 1, no = 0), and unstable home life (yes = 1, stable = 0). Low-risk (0 to 2 risk factors), medium-risk (3 factors), and high-risk (4 to 6 factors) groups of offenders were formed. Univariate ANCOVAs indicated that the high-risk group reported less family cohesion, more aggression, lower self-esteem, more social discomfort, and more frequent and extreme sexual fantasies. The implications of these findings for differential identification of and interventions with adolescent sex offenders are discussed.     

Driving under the influence of chlormethiazole

This article describes a case of driving under the influence of the sedative-hypnotic-anticonvulsant drug chlormethiazole. The suspect, who was a physician, was driving dangerously on a busy highway and caused a traffic collision. When apprehended by the police, the man had bloodshot and glazed eyes and pupil size was enlarged. He could not answer the questions properly and his gait was unsteady. A roadside breath-alcohol screening test was positive but an evidential breath-alcohol test conducted about one hour later was below the legal limit for driving of 0.10 mg/L (10 microg/100 mL or 0.021 g/210 L). Because of the special circumstances of the traffic crash and the man's appearance and behaviour, the police suspected that drugs other than alcohol were involved and obtained a venous blood sample for toxicological analysis. The blood contained 0.23 mg/g alcohol, which is above the legal limit for driving in Sweden 0.20 mg/g (20 mg/100 mL or 0.020 g/100 mL), and codeine was also present at a therapeutic concentration of 0.02 mg/L. The conflict between the clinical signs of impairment and the toxicology report prompted a reanalysis of the blood sample with major focus on sedative-hypnotic drugs. Analysis by capillary GC-NPD identified chlormethiazole at a concentration of 5mg/L, the highest so far encountered in traffic cases in Sweden. In 13 other impaired driving cases over 10 years the mean (median) and range of concentrations of chlormethiazole were 1.6 mg/L (1.6 mg/L) and 0.3-3.3 mg/L. This case report underscores the need to consider clinical observations and the person's behaviour in relation to the toxicology report when interpreting and testifying in drug-impaired driving cases.     

Plea Agreements in the ICTY: Purpose, Effects and Propriety

Plea agreements have an impact on a number of issues affectingvictims or perpetrators, extending beyond the resource and investigativeadvantages that prompted the growing use of plea agreementsin the International Criminal Tribunal for the former Yugoslavia(ICTY). This article considers whether these effects advanceor offend the objectives underlying the establishment of theICTY. It argues that the plea-agreement process has positiveconsequences for the creation of a historical record and forproviding an opportunity for victims to be heard. It also contendsthat recent rulings have reduced the possibility that plea agreementsmight result in unequal treatment of convicted persons or dismissalof critical charges. Finally, the article suggests that theultimate contribution of plea agreements to the work of theICTY should be viewed not principally as a saving in resources,but rather as a tool for furthering accountability and justiceunder the all too real pressures of limited time and resourceson the fulfilment of the ICTY's mandate.     

The cost-effectiveness of methanol for reducing motor vehicle emissions and urban ozone

This article analyzes the costs and emissions characteristics of methanol vehicles. The cost-effectiveness of methanol—the cost per ton of reactive hydrocarbon emissions reduced—is calculated and compared to the cost-effectiveness of other hydrocarbon reduction strategies. Methanol is found to cost from $33,000 to nearly $60,000 per ton, while several other options are available for under $10,000 per ton. The cost per part-per-million reduction in peak ambient ozone levels is also computed for two cities, Houston and Philadelphia. Despite the greater improvement in ozone in Philadelphia than Houston, methanol is found to be more cost-effective in Houston. This result occurs because Houston's distribution and marketing costs are lower than Philadelphia's. The costs in both cities, however, are far higher than estimates of the benefits from acute health improvements. Finally, the reduction in ozone exposure in Los Angeles is estimated and the costs of the reduction compared with an estimate of acute health benefits. Again, the benefits fall far short of the costs.     

NGOs and income-generation projects: Lessons from the Joint Funding Scheme

A visit to a number of small enterprise and income-generation projects supported under the ODA's Joint Funding Scheme in Zimbabwe and Kenya has raised a series of key points which have wider implications for practitioners and donors. The article discusses each point and makes nine ‘recommendations?s for NGOs and donors who support them. While the general benefits of NGOs — such as their relatively low cost, ability to reach the poor, and innovativeness — are affirmed, the article argues that the challenge facing NGOs is to progress further from this base. In particular, it argues that NGOs need to develop more business-like operations, focusing on the most practicable forms of enterprise structure, but without losing their priority of seeking to benefit the poor and other disadvantaged groups. Technology-oriented projects need to ensure that they concentrate on the application of technology in a market context, rather than developing it for its own sake. NGOs with donors need also to strive for a realistic definition of sustainability, to work towards a more credible project-planning process, and to be aware of the dangers of very visible and expensive investment in project transport undermining NGOs' efficiency.
