DNA mixtures in forensic casework: a 4-year retrospective study

Occasionally interpretation guidelines from validation studies are difficult to apply to real forensic casework, especially in the case of mixed samples. Exogenous contamination, an unknown number of contributors or unbalanced proportion of each one in the sample and a varied degree of degradation of the biological materials, contribute to the difficulties in the interpretation of sample profiles. In this paper we have reviewed all the mixed genetic STR profiles encountered in our laboratory over 4 years (1997-2000) and evaluated the problems in the interpretation of the results. From 1547 criminal cases with 2424 samples typed, 163 showed a mixed profile (6.7%). We have observed that occasionally, a mixture appeared in the same sample with one multiplex amplification kit (e.g. Blue) and not with another (e.g. Green). From our results, it can be suggested that technical characteristics of the different fluorochrome groups in the multiplexes override the molecular characteristics of each STR in their capacity to detect mixtures.     

Radiographic evaluation of third molar development in Spanish children and young people

Third molar development was evaluated in 786 young people aged between 4 and 20 years, all patients at the School of Dentistry of the University of Granada. The development of third molars and of mandibular second premolars and second molars was determined according to the stages proposed by Nolla. The onset of mandibular third molar formation was observed at very variable ages in this series, ranging from 5.86 to 14.66 years. The first developmental stages of maxillary third molars are not usually visible radiographically, which can lead to an incorrect diagnosis of agenesis. We found no significant relationship between the gender or age of the patient and the presence or absence of third molars. However, the presence/absence of the third molar can be predicted in 82.82% of cases when there is some degree of calcification of mandibular second molars and second premolars.     

Contextualizing depression and physical functioning in battered women: adding vulnerability and resources to the analysis

This investigation examined the relationships between physical, psychological, and sexual abuse along with vulnerability appraisals, positive and negative social relations, and socioeconomic resources on battered women's depression symptomatology and physical functioning. Women were recruited following an incident of partner violence that resulted in a police-report or the filing of a protection order. Participants were surveyed using a standardized questionnaire. Bivariate correlations and multiple regressions were used to examine the relationships between predictors as well as the cumulative and unique contributions of each variable set in explaining depression and physical functioning. Findings indicate that vulnerability appraisals, social relations, and socioeconomic resources significantly explain women's depression and physical functioning over and above the unique effect of specific types of partner violence. Given that women's physical and mental health are important aspects of assisting women with safety planning and violence cessation strategies, implications for assessment and interventions for battered women are discussed.

Pink‐Collar Representation and Budgetary Outcomes in US States

Legislatures worldwide are dominated by wealthy elites, who are often out of touch with the needs and problems of citizens. Research shows that the underrepresentation of the working class matters in terms of policy processes and outcomes. Yet the research on class has largely focused on blue‐collar representatives, who are primarily men. Working‐class women are more likely to hold pink‐collar jobs, or low‐status occupations dominated by women. We argue that pink‐collar legislators are uniquely positioned to legislate over education and social service policy. To test our argument, we combine a new coding of working‐class backgrounds that accounts for pink‐collar representation with state spending data on education and social services from US states over time. Modeling compositional budget data, we find that class and gender intersect to shape policy outcomes via state budget allocations, with women's pink‐collar representation associated with increased spending on both education and social services.     

Hidden corporate profits in the U.S. prison system: the unorthodox policy-making of the American Legislative Exchange Council

Using a leaked document trove containing 800 model bills, we analyze the American Legislative Exchange Council’s (ALEC) hidden corporate profit making in the prison–industrial complex. We find that ALEC seeks to expand the private prison industry in three ways: (1) promoting greater use of private prisons, goods, and services, (2) promoting greater use of prison labor, and (3) increasing the size of the prison population. ALEC’s efforts to increase the prison population by expanding definitions of existing crime, creating new crimes, enhancing enforcement of existing crimes, amending the trial process to increase the likelihood of incarceration, and lengthening prison sentences for crimes pose a threat to civil liberties. ALEC’s unorthodox policy approach exemplifies John Gaventa’s theory that powerful interests maintain their power by creating conditions in which citizens are not able to identify and advocate on behalf of their interests.     

Father Involvement in Dependency Review Hearings

Understanding the impact of fathers in child maltreatment cases has been a neglected area of research. This study evaluated differences in child welfare hearings and children's perceptions of their situation where fathers were and were not present. Father attendance at hearings appeared to positively impact information-gathering. When fathers attended hearings, they lasted longer and covered case topics more thoroughly. Children reported more negative affect immediately after hearings where fathers were present; however, these differences were attenuated at subsequent interviews. Overall, the findings suggest that father involvement positively impacts case management, though more research must be conducted to support this finding.     

Don't help victims of crime if you don't have the time: Assessing support for Good Samaritan laws

Criminologists tend to study crimes that include active behaviors by offenders. Much less attention is given to inaction - or crimes that are defined by the absence of behaviors. A number of different crimes of omission, however, are included within state statutes. In recent times, a great deal of legislative attention has been directed towards whether Good Samaritan laws should be developed- laws that require bystanders to help those who are imperiled. This article describes a pilot study involving a survey of 134 “bystanders” to determine their attitudes about helping and their support for laws mandating that bystanders help crime victims. Results show that the sample overwhelmingly indicated that they would help others themselves, but there was mixed support for laws requiring that individuals help those in need. Support for Bad Samaritan laws was related to age and education. Implications are provided.
