Quantifying Alcohol-Related Mortality: Should Alcohol-Related Contributory Causes of Death be Included?

Aims: The aim of the study was to assess whether alcohol-related mortality data in the UK should be extended to include contributory as well as underlying cause of death. Methods: A total of 101,320 deaths registered in Northern Ireland between 2001 and 2007 were analysed to determine the quantity and characteristics of those with an underlying or contributory alcohol-related cause of death. Results: Alcohol was found to be an underlying cause of death in 1690 cases (1.7% of deaths) and a contributory cause in a further 1105 cases. Analyses show that the addition of alcohol-related contributory causes of deaths would increase the male-female ratio, result in steeper socio-economic gradients and amplify the apparent rate of increase of alcohol-related deaths. The significant contribution of alcohol to external causes of death, such as accidents and suicide, is also more evident. Conclusions: Using only underlying cause of death undoubtedly underestimates the burden of alcohol-related harm and may provide an inaccurate picture of those most likely to suffer from an alcohol-related death, especially among younger men.

Science for sale in a free market economy: But at what price? ABA and the treatment of autism in Europe.

Educating the public accurately about Applied Behavior Analysis (ABA) is an important undertaking, not least because misconceptions and myths about ABA abound. In this paper we argue that, unfortunately, the efforts of many dedicated professionals and parents to disseminate accurate information about the benefits of ABA for children diagnosed with autism spectrum disorder (ASD) are damaged by a few behavior analysts whose focus seems to be more on monetary gains than social responsibility. We cite examples of the resulting harm to the public image of behavior analysis from a number of European countries. We conclude by calling upon fellow scientists to unite in their opposition to unscrupulous abuses of free market forces for short-term monetary gains that damage the dissemination of the science of behavior analysis and thereby ultimately disadvantage those who should benefit primarily from our science, i.e., some of the most vulnerable citizens of society.

The Perils of Moviegoing in America, 1896-1950

The Perils of Moviegoing in America is a film history that examines the various physical and (perceived) moral dangers facing audiences during the first fifty years of film exhibition.

Chapter 1: “Conflagration”
As early as 1897, a major fire broke out at a film exhibition in San Francisco, with flames burning the projectionist and nearby audience members. From that point until the widespread adoption of safety stock in 1950, fires were a very common movie-going experience. Hundreds of audience members lost their lives in literally thousands of theatre fires, ranging from early nickelodeons to the movie palaces of the thirties and forties.

Chapter 2: “Thieves Among Us”
Bandits robbed movie theatres on hundreds of occasions from the early days of film exhibition through the end of the Great Depression. They held up ticket booths, and they dynamited theatre safes. They also shot theatre managers, ushers, and audience members, as a great many of the robberies occurred while movies were playing on the screens inside.

Chapter 3: “Bombs Away”
Bombings at movie theatres became common in small towns and large cities on literally hundreds of occasions from 1914 to the start of World War II. Some were incendiary bombs, and some were stench bombs; both could be fatal, whether due to explosions or to the trampling of panicked moviegoers

Chapter 4: “It’s Catching”
Widespread movie-going in the early 20th century provoked an outcry from numerous doctors and optometrists who believed that viewing films could do irreparable harm to the vision of audience members. Medical publications (including the Journal of the American Medical Association) published major studies on this perceived problem, which then filtered into popular-audience magazines and newspapers.

Chapter 5: “The Devil’s Apothecary Shops”
Sitting in the dark with complete strangers proved worrisome for many early filmgoers, who had good reason to be concerned. Darkness meant that prostitutes could easily work in the balconies of some movie theatres, as could “mashers” who molested female patrons (and sometimes children) after the lights were dimmed. That was all in addition to the various murderers who used the cover of darkness to commit their crimes at movie theatres.

Chapter 6: “Blue Sundays”
Blue laws were those regulations that prohibited businesses from operating on Sundays. Most communities across the US had such legislation on their books, which by the nickelodeon era were at odds with the thousands of filmgoers who went to the movies every Sunday. Theatre managers were often arrested, making newspaper headlines over and over again. Police sometimes even arrested entire film audiences as accomplices in the Blue Law violations.

Chapter 7: “Something for Nothing”
In an effort to bolster ticket sales, many movie theatres in the 1910s began to hold lotteries in which lucky audience members won cash prizes; by the time of the Great Depression, lotteries like “Bank Night” became a common aspect of the theatre-going enterprise. However, reception studies have generally overlooked the intense (and sometimes coordinated) efforts by police, politicians, and preachers to end this practice, which they viewed as illegal and immoral gambling.

Quantum efficiency in GaAs Schottky photodetectors with enhancement due to surface plasmon excitations

The overall quantum efficiency in surface plasmon (SP) enhanced Schottky barrier photodetectors is examined by considering both the external and internal yield. The external yield is considered through calculations of absorption and transmission of light in a configuration that allows reflectance minimization due to SP excitation. Following a Monte Carlo method, a procedure is presented to estimate the internal yield while taking into account the effect of elastic and inelastic scattering processes on excited carriers subsequent to photon absorption. The relative importance of internal photoemission and band-to-band contributions to the internal yield is highlighted along with the variation of the yield as a function of wavelength, metal thickness and other salient parameters of the detector.

On Testing the 'Moral Law'

In a previous article in this journal, Daniel Kelly, Steven Stich, Kevin Haley, Serena Eng and Dan Fessler report data that, according to them, foster scepticism about an association between harm and morality existent in the Turiel tradition (Kelly et al., 2007). This article challenges their interpretation of the data. It does so by explicating some methodological problems in the Turiel tradition that Kelly et al. themselves in a way inherit and by drawing on new evidence coming from a partial replication of their research.

The extent and nature of family alcohol and drug use: Findings from the Belfast Youth Development Study

Using data from an ongoing longitudinal study of adolescent drug use, this study examines the proportion of teenagers living with parents who are problem alcohol or drug users. Around two percent of parents report high levels of problem drinking and one per cent report problem drug use. If a broader definition of hazardous drinking is used, the proportion of teenagers exposed increases to over 15 per cent. When substance use is examined at a family level (taking account of alcohol and drug use amongst dependent children in addition to that of parents), the proportion of families experiencing some form of substance use is considerable. These findings add further support to the call for increased recognition of the needs of dependent children within adult treatment services when working with parents. Likewise, the reduction of harm to children as a result of parent substance use should be an increasingly important priority for family support services. This is likely to be achieved through the closer integration of addiction and family services.

The effect of essentialism in settings of historic intergroup atrocities

Three studies tested the effects of essentialist beliefs regarding the national ingroup in situations where a perpetrator group has inflicted harm on a victim group. For members of the perpetrator group, it was hypothesised that ‘essentialism’ has a direct positive association with ‘collective guilt’ felt as a result of misdeeds conducted by other ingroup members in the past. Simultaneously, it was hypothesised to have an indirect negative association with collective guilt, mediated by perceived threat to the ingroup. Considering these indirect and direct effects jointly, it was hypothesised that the negative indirect effect suppresses the direct positive effect, and that the latter would only emerge if perceived ‘ingroup threat’ was controlled for. This was tested in a survey conducted in Latvia among Russians (N?=?70) and their feelings toward how Russians had treated ethnic Latvians during the Soviet occupation; and in a survey in Germany among Germans (N?=?84), focussing on their feelings toward the Holocaust. For members of the victim group, it was hypothesised that essentialism would be associated with more anger and reluctance to forgive past events inflicted on other ingroup members. It was proposed that this effect would be mediated by feeling connected to the ingroup victims. This was tested in a survey conducted among Hong Kong Chinese and their feelings toward the Japanese and the Nanjing massacre (N?=?56). Results from all three studies supported the hypotheses.

Anisotropic seismic inversion using a multigrid Monte Carlo approach

We propose a new approach for the inversion of anisotropic P-wave data based on Monte Carlo methods combined with a multigrid approach. Simulated annealing facilitates objective minimization of the functional characterizing the misfit between observed and predicted traveltimes, as controlled by the Thomsen anisotropy parameters (epsilon, delta). Cycling between finer and coarser grids enhances the computational efficiency of the inversion process, thus accelerating the convergence of the solution while acting as a regularization technique of the inverse problem. Multigrid perturbation samples the probability density function without the requirements for the user to adjust tuning parameters. This increases the probability that the preferred global, rather than a poor local, minimum is attained. Undertaking multigrid refinement and Monte Carlo search in parallel produces more robust convergence than does the initially more intuitive approach of completing them sequentially. We demonstrate the usefulness of the new multigrid Monte Carlo (MGMC) scheme by applying it to (a) synthetic, noise-contaminated data reflecting an isotropic subsurface of constant slowness, horizontally layered geologic media and discrete subsurface anomalies; and (b) a crosshole seismic data set acquired by previous authors at the Reskajeage test site in Cornwall, UK. Inverted distributions of slowness (s) and the Thomson anisotropy parameters (epsilon, delta) compare favourably with those obtained previously using a popular matrix-based method. Reconstruction of the Thomsen epsilon parameter is particularly robust compared to that of slowness and the Thomsen delta parameter, even in the face of complex subsurface anomalies. The Thomsen epsilon and delta parameters have enhanced sensitivities to bulk-fabric and fracture-based anisotropies in the TI medium at Reskajeage. Because reconstruction of slowness (s) is intimately linked to that epsilon and delta in the MGMC scheme, inverted images of phase velocity reflect the integrated effects of these two modes of anisotropy. The new MGMC technique thus promises to facilitate rapid inversion of crosshole P-wave data for seismic slownesses and the Thomsen anisotropy parameters, with minimal user input in the inversion process.

Dynamic pricing models for used products in remanufacturing with lost-sales and uncertain quality

In this paper, we investigate the remanufacturing problem of pricing single-class used products (cores) in the face of random price-dependent returns and random demand. Specifically, we propose a dynamic pricing policy for the cores and then model the problem as a continuous-time Markov decision process. Our models are designed to address three objectives: finite horizon total cost minimization, infinite horizon discounted cost, and average cost minimization. Besides proving optimal policy uniqueness and establishing monotonicity results for the infinite horizon problem, we also characterize the structures of the optimal policies, which can greatly simplify the computational procedure. Finally, we use computational examples to assess the impacts of specific parameters on optimal price and reveal the benefits of a dynamic pricing policy. © 2013 Elsevier B.V. All rights reserved.

Improved conjugate gradient implementation for least squares support vector machines

As a promising method for pattern recognition and function estimation, least squares support vector machines (LS-SVM) express the training in terms of solving a linear system instead of a quadratic programming problem as for conventional support vector machines (SVM). In this paper, by using the information provided by the equality constraint, we transform the minimization problem with a single equality constraint in LS-SVM into an unconstrained minimization problem, then propose reduced formulations for LS-SVM. By introducing this transformation, the times of using conjugate gradient (CG) method, which is a greatly time-consuming step in obtaining the numerical solution, are reduced to one instead of two as proposed by Suykens et al. (1999). The comparison on computational speed of our method with the CG method proposed by Suykens et al. and the first order and second order SMO methods on several benchmark data sets shows a reduction of training time by up to 44%.

Doping, sport and the law: time for repeal of prohibition?

This article concerns the legal issues that surround the prohibition of doping in sport. The current policy on the use of performance enhancing drugs (PEDs) in sport is underpinned by both a paternalistic desire to protect athletes’ health and the long-term integrity or ‘spirit’ of sport. The policy is put into administrative effect globally by the World Anti-Doping Agency (WADA), which provides the regulatory and legal framework through which the vast majority of international sports federations harmonise their anti-doping programmes. On outlining briefly both the broad administrative structures of international sport’s various anti-doping mechanisms, and specific legal issues that arise in disciplinary hearings involving athletes accused of doping, this article questions the sustainability of the current ‘zero tolerance’ approach, arguing, by way of analogy to the wider societal debate on the criminalisation of drugs, and as informed by Sunstein and Thaler’s theory of libertarian paternalism, that current policy on anti-doping has failed. Moreover, rather than the extant moral and punitive panic regarding doping in sport, this article, drawing respectively on Seddon’s and Simon’s work on the history of drugs and crime control mentality, contends that, as an alternative, harm reductionist measures should be promoted, including consideration of the medically supervised use of certain PEDs.

'Grooming' and the Sexual Abuse of Children:Institutional, Internet and Familial Dimensions

‘Grooming’ and the Sexual Abuse of Children: Institutional, Internet and Familial Dimensions critically examines the official and popular discourses on grooming, predominantly framed within the context of on-line sexual exploitation and abuse committed by strangers, and institutional child abuse committed by those in positions of trust.

Set against the broader theoretical framework of risk, security and governance, this book argues that due to the difficulties of drawing clear boundaries between innocuous and harmful motivations towards children, pre-emptive risk-based criminal law and policy are inherently limited in preventing, targeting and criminalising ‘grooming’ behaviour prior to the manifestation of actual harm. Through examination of grooming against the complexities of the onset of sexual offending against children and its actual role in this process, the author broadens existing discourses by providing a fuller, more nuanced conceptualisation of grooming, including its role in intra-familial and extra-familial contexts. There is also timely discussion of new and emerging forms of grooming, such as ‘street’ or ‘localised’ grooming, as typified by recent cases in Rochdale and Oldham, and ‘peer-to-peer’ grooming.

The first inter-disciplinary, thematic, and empirical investigation of grooming in a multi-jurisdictional context, ‘Grooming’ and the Sexual Abuse of Children draws on extensive empirical research in the form of over fifty interviews with professionals, working in the fields of sex offender risk assessment, management or treatment, as well as child protection or victim support in the four jurisdictions of the United Kingdom and the Republic of Ireland. Impeccably presented and meticulously considered, this book will be of interest to criminologists and those working and studying in the field of policing and criminal justice studies, as well as policy makers and practitioners in the areas of child protection and sex offender management.
