Multidimensional scaling and the analysis of sexual offence behaviour: a reply to Sturidsson et al.

Abstract

Sturidsson et al. (Psychology, Crime & Law, 12, 221–230, 2006) published an article on the replicability of early multidimensional scaling (MDS) behavioural research by Canter and Heritage (Journal of Forensic Psychiatry, 1, 185–212, 1990). Sturidsson et al. were unable to find a ‘readily apparent, simple interpretation’ of their MDS solution and therefore suggested that the MDS approach may be flawed as a device for interpreting sexual assault. The current paper explains how the methods employed by Sturidsson et al. represent an incorrect use of MDS, specifically in their input of Jaccard similarity data into the MDS (ALSCAL) procedure in SPSS as opposed to the correct MDS (PROXSCAL) procedure. A comparative example is used to illustrate how adopting the ALSCAL procedure will result in an inverse MDS solution, where objects appearing closer together are more dissimilar, making interpretation of the MDS plot meaningless in this context. The current paper discusses this methodological flaw in greater depth and in the context of behavioural investigative research using MDS in general. It concludes with some general guidelines in utilizing the MDS procedure in SPSS specific to criminal profiling research.

Back to first principles: a new model for the regulation of drug promotion

The US Food and Drug Administration''s (‘FDA’ or the ‘Agency’) current regulatory framework for drug promotion, by significantly restricting the ability of drug manufacturers to communicate important, accurate, up-to-date scientific information about their products that is truthful and non-misleading, runs afoul of the First Amendment and actually runs counter to the Agency''s public health mission. Our article proposes a New Model that represents an initial proposal for a modern, sustainable regulatory framework that comprehensively addresses drug promotion while protecting the public health, protecting manufacturers’ First Amendment rights, establishing clear and understandable rules, and maintaining the integrity of the FDA approval process. The New Model would create three categories of manufacturer communications—(1) Scientific Exchange and Other Exempt Communications, (2) Non-Core Communications, and (3) Core Communications—that would be regulated consistent with the First Amendment and according to the strength of the government''s interest in regulating the specific communications included within each category. The New Model should address the FDA''s concerns related to off-label speech while protecting drug manufacturers’ freedom to engage in truthful and non-misleading communications about their products.     

Concussions and youth football: using a public health law framework to head off a potential public health crisis

Concussion from sport is increasingly recognized as a public health priority. In response, all states and the District of Columbia have enacted youth concussion legislation. This paper first examines key developments in concussion-related policy and legislation and then uses the findings from recent scientific studies to highlight the need to incorporate evolving scientific evidence into concussion legislation in order to better protect youth and adolescent athletes. Next, the paper discusses the framework of empirical health law research and why it should be applied in the case of concussion legislation. Finally, this paper argues that empirical health law research should be considered in any decision about whether legislation can help improve the health and safety of young players, a particularly vulnerable population whose unique needs have not yet been adequately addressed.     

Moving prison health promotion along: towards an integrative framework for action to develop health promotion and tackle the social determinants of health

The majority of prisoners are drawn from deprived circumstances with a range of health and social needs. The current focus within ‘prison health’ does not, and cannot, given its predominant medical model, adequately address the current health and well-being needs of offenders. Adopting a social model of health is more likely to address the wide range of health issues faced by offenders and thus lead to better rehabilitation outcomes. At the same time, broader action at governmental level is required to address the social determinants of health (poverty, unemployment and educational attainment) that marginalise populations and increase the likelihood of criminal activities. Within prison, there is more that can be done to promote prisoners’ health if a move away from a solely curative, medical model is facilitated, towards a preventive perspective designed to promote positive health. Here, we use the Ottawa Charter for health promotion to frame public health and health promotion within prisons and to set out a challenging agenda that would make health a priority for everyone, not just ‘health’ staff, within the prison setting. A series of outcomes under each of the five action areas of the Charter offers a plan of action, showing how each can improve health. We also go further than the Ottawa Charter, to comment on how the values of emancipatory health promotion need to permeate prison health discourse, along with the concept of salutogenesis.
