Still three Wales? Social location and electoral behaviour in contemporary Wales

Wales provides a notable exception to the contemporary academic consensus that electoral behaviour is best studied via choice-based approaches. In Wales, the orthodoxy remains that of the Three-Wales Model, an approach formulated in the 1980s which saw voting behaviour as defined by class, language and national identity. This article submits the Three-Wales Model to detailed scrutiny for the first time. The model is argued to have been constructed on a very narrow theoretical basis, and on flawed measurements. Most importantly, however, the Three-Wales Model is shown to have little empirical leverage on voting behaviour in Wales – either for the period when it was formulated or for more recent elections. Factors associated with ‘valence politics’ theories are shown to provide far greater insight into voting behaviour in contemporary Wales.     

Fracture patterns on the infant porcine skull following severe blunt impact

The objective of this study was to document patterns of fracture on infant porcine skulls aged 2-28 days (n = 57) because of a single, high energy blunt impact to the parietal bone with rigid (nondeformable) and compliant (deformable) interfaces. Fracture patterns were mapped using Geographic Information System software. For the same generated impact force, the rigid interface produced more fractures than the compliant interface for all ages. This study also showed that this increased level of impact energy versus an earlier study using a lower energy resulted in new sites of fracture initiation and also caused previously defined fractures that propagate into an adjacent bone. Several unique characteristics of bone and diastatic fracture were documented as a function of specimen age, impact energy, and interface. These data describe some baseline characteristics of skull fracture using an animal model that may help guide future studies from forensic case files.     

Is There a Relationship Between Bladder Outlet Obstruction due to Benign Prostatic Hyperplasia and Pulmonary Thromboembolism?

Benign prostatic hyperplasia with chronic bladder outlet obstruction has been associated with deep venous thrombosis (DVT) and fatal pulmonary thromboembolism (PTE). To evaluate this further, 60 autopsy cases of men with PTE were compared with 60 age-matched controls. The criteria for outlet obstruction were macroscopic prostatic enlargement with bladder trabeculation and benign prostatic hyperplasia on microscopy. Ten of the 60 men (16.7%) with fatal PTE had evidence of bladder outlet obstruction (age 57-78 years; mean 71.4 years). Of the 60 controls, 12 had evidence of bladder outlet obstruction (20%) (age 67-86 years; mean 75.5 years). No significant relationship could be demonstrated between bladder outlet obstruction and fatal PTE cases (p = 0.8). Given reports of this association, however, it is possible that bladder distension with venous compression may act as a risk modifier in certain individuals in association with other significant comorbidities, but this risk appears low.     

Autoerotic death: incidence and age of victims--a population-based study

Review of the Australian National Coronial Information System and the Swedish National Forensic Database was undertaken over a 7-year period from 2001 to 2007 for all cases where death had been attributed to autoerotic death or sexual asphyxia. In Australia, there were 44 cases (M:F = 42:2) with the majority of victims aged >30 years (77%)-a yearly national rate of approximately 0.3/million. In Sweden, there were nine cases (M:F = 9:0) with the majority of cases aged <30 years (55%)-a yearly national rate of approximately 0.14/million. The usual male predominance was present in both populations, although the Australian victims were older than is usually reported. Lethal sexual asphyxia is uncommon in both the Australian and Swedish populations, with a lower rate than has been cited for North America. Whether this is because of different kinds of paraphilic activities in different populations or of differences in methods of central data collection is uncertain.     

How reliable is cloudsourcing? A review of articles in the technical media 2005–11

A review of articles in the technical media between 2005 and 3Q 2011 disclosed reports on 49 outages involving 20 cloudsourcing providers. Several of these were major events. Many caused difficulties for user-organisations’ staff. Some caused lengthy suspension of services by user-organisations to their customers. A number of them involved irretrievable loss of data. Many user-organisations have failed to risk-assess their use of cloudsourcing, and are exposing their businesses to unmanaged risks.     

After Columbia: The Space Shuttle Program and the Crisis in Space Access

The loss of the Space Shuttle Columbia on 1 February 2003 brought to the fore the sad history of the Space Shuttle's origins, evolution, operation, and the continuing challenge of space access. The crisis that emerged in human access to space because of the accident was greater than any experienced since the end of the Apollo program more than thirty years earlier. This essay explores the origins and operations of the Space Shuttle, the varied efforts to build a successor vehicle versus upgrading the shuttle fleet, and suggests that the first decade of the twenty-first century promises to offer both serious challenges and enormous potential for the development of new launch vehicles that may finally achieve the long-held dream of reliable, affordable access to space. The essay ends by asking whether or not the half-hearted quest for a shuttle replacement might not portend the demise human spaceflight for the United States.
