Lessons from the Gang Lu Murders

This paper offers a critical review and reflection of the 1991 University of Iowa shootings. Gang Lu, a disgruntled Iowa graduate student, was initially angered over perceived slights he was receiving from his academic department. When he felt that his concerns were left unanswered by the University, he decided to seek revenge on those whom he felt were responsible. In doing so, he murdered five individuals and paralyzed another before taking his own life. This paper seeks to reflect on these shootings twenty years after the occurrence and to offer a discussion of some of the larger societal themes raised by this tragedy.     

From ‘There is No Alternative’ to ‘Maybe There are Alternatives’: five Challenges to Economic Orthodoxy after the Crash

Prior to the 2008 financial crisis, politicians famously told the public and themselves that ‘there is no alternative’ to a neoliberal economic paradigm. Fast‐forward to 2019 and there is, instead, the sense that ‘maybe there are alternatives’. However, when many observers and commentators look back to the 2008 crisis, they see a general continuity with what went before. In order to gain a better understanding of this ‘interregnum’, we map five sets of ideas and practices that challenge the policies, ideas, and conventions of pre‐crash orthodoxy. In doing so, we argue that there has been a fundamental transformation in legitimate public discourse about the economy since 2008: ideas and practices that were previously unimaginable or illegitimate in mainstream economic debate are now commonplace. Although this does not represent a ‘paradigm shift’, it represents significant political change that is important to understand and interrogate on its own terms.     

Policy Design and Nodal Governance: A Comparative Analysis of Determinants of Environmental Policy Change in a South African City

Abstract

This contribution focuses on a policy paradox, a failed attempt to introduce a Solar Water Heater bylaw in a South African city in spite of much initial support, both politically and professionally. The paper combines a policy design and a nodal governance perspective to explain why the law failed to materialise. It uses categories developed by the nodal governance approach to characterise the mentalities and technologies of the public agencies involved in the policy process, and explore how distinct policy cultures are nurtured by the networked relations and concomitant learning contexts of these agencies. The analysis shows how the agencies differ sharply on philosophical and practical grounds as to how they typically think about policy values and interventions. This tends to make the collaboration between them difficult as each of them experiences the other as seeking to frustrate rather to assist the policy process. The paper documents how “superstitious learning” became a predominant trait of the bylaw process, as each of the agencies tended to look for evidence in the actions of officials in the other department that confirmed their stereotypical view of them, and reinforced it during the process of interaction. Insufficient attention was given, early on in the bylaw process, to the fact that these departments would have to cooperate closely and that “buy-in” from both was a critical condition for success. Due to this, unfortunate policy design choices fed forward through the implementation process and disabled opportunities for co-learning and collective problem-solving.     

Identification of group affinity from cross-sectional contours of the human midfacial skeleton using digital morphometrics and 3D laser scanning technology

Identifying group affinity from human crania is a long-standing problem in forensic and physical anthropology. Many craniofacial differences used in forensic skeletal identification are difficult to quantify, although certain measurements of the midfacial skeleton have shown high predictive value for group classifications. This study presents a new method for analyzing midfacial shape variation between different geographic groups. Three-dimensional laser scan models of 90 crania from three populations were used to obtain cross-sectional midfacial contours defined by three standard craniometric landmarks. Elliptic Fourier transforms of the contours were used to extract Fourier coefficients for statistical analysis. After cross-validation, discriminant functions based on the Fourier coefficients provided an average of 86% correct classifications for crania from the three groups. The high rate of accuracy of this method indicates its usefulness for identifying group affinities among human skeletal remains and demonstrates the advantages of digital 3D model-based analysis in forensic research.     

An analytical evaluation of eight on-site oral fluid drug screening devices using laboratory confirmation results from oral fluid

A decaying cadaver emits volatile organic compounds that are used by necrophilous and necrophagous insects in order to find their brood substrate. Although volatile organic compounds (VOCs) that are released by carcasses have been identified, little is known about the specific compounds that are used by these insects while searching for a brood substrate. Therefore, we have investigated the chemical ecology involved in the attraction of the necrophagous hide beetle Dermestes maculatus, which feeds as an adult and larva upon decomposing carcasses. Our aims have been to identify the responsible compounds in the odours of the carcass that are important for the attraction of the beetles. Furthermore, we have studied sex- and age-related differences in beetle attraction and tested whether the hide beetle can distinguish between various stages of decomposition by means of the emitted odours. Headspace collection of volatiles released from piglet carcasses (bloated stage, post-bloating stage, advanced decay and dry remains), coupled gas chromatography-mass spectrometry (GC-MS), gas chromatography with electroantennographic detection (GC-EAD) and bioassays were conducted to identify the volatiles responsible for the attraction of the beetles. Freshly emerged male beetles were attracted by the odour of piglets in the post-bloating stage (9 days after death; T(mean) = 27 °C) and the EAD-active compound benzyl butyrate. Statistical analysis revealed a higher relative proportion of benzyl butyrate in the odour bouquet of the post-bloating stage in comparison with the other stages. We therefore conclude that this compound plays an important role in the attraction of hide beetles to carcass odour. This underlines the potential use of D. maculatus for the estimation of the post mortem interval. The decomposition stage at which the female beetles are attracted to the odour of a cadaver remains unknown, as does the nature of this attraction. Pheromones (sexual or aggregation pheromones) might play an essential role correlated with their attraction to carrion and consequently with their attraction to the substrate for mating and ovipositioning.     

Children's experiences of domestic violence: developing an integrated response from police and child protection services

Police notifications of incidents of domestic violence to child protection services constitute an acknowledgement of the harm that domestic violence inflicts on children. However, these notifications represent a substantial demand on child welfare services and the outcomes for children and victims of domestic violence have been questioned. This paper presents findings from the first UK study to examine these notifications in depth and examines the interface between the police and child protection services in responding to domestic violence incidents. The research reports on police interventions in 251 incidents of domestic violence involving children; the communication of information to child protection services and the subsequent filtering and service response. Social workers found that notifications conveyed little information on children's experiences of domestic violence. Forty per cent of families notified had had no previous contact with child protection services in that area, but those cases most likely to receive social work assessment or intervention were those where the case was already open. Notifications triggered a new social work intervention in only 5% of cases. The study also identified a range of innovative approaches for improving the co-ordination of police and child protective services in relation to children's exposure to domestic violence. Arrangements that maximized opportunities for police and social workers to share agency information appeared to offer the best option for achieving informed decisions about the appropriate level of service response to children and families experiencing domestic violence.
