Quantum Griffiths Inequalities
No full textWe present a general framework of Griffiths inequalities for quantum systems. Our approach is based on operator inequalities associated with self-dual cones and provides a consistent viewpoint of the Griffiths inequality. As examples, we discuss the quantum Ising model, quantum rotor model, Bose-Hubbard model, and Hubbard model. We present a model-independent structure that governs the correlation inequalities

Gaming addiction in adolescence (revisited)
No full textGaming addiction has become a topic of increasing research interest. Over the last 25 years, I have written many articles on adolescent video gaming for Education and Health as it is one of the research fields that is constantly evolving. In fact, over the last decade, there has been a significant increase in the number of scientific studies examining various aspects of online addiction particularly among adolescents and young adults (Kuss & Griffiths, 2012; Kuss, Griffiths, Karila & Billieux, 2014). Although the amount and the quality of research in the field has progressed much over this period, it is still in its infancy compared to other more established behavioural addictions (such as pathological gambling). This article briefly examines (i) how adolescent gaming addiction research has changed over the last three decades, (ii) how online gaming addiction has gained genuine psychiatric status, (iii) excessive gaming as an addiction, and (iv) where the gaming addiction field is going
A Systematic Review of Online Sex Addiction and Clinical Treatments Using CONSORT Evaluation
No full textResearchers have suggested that the advances of the Internet over the past two decades have gradually eliminated traditional offline methods of obtaining sexual material. Additionally, research on cybersex and/or online sex addictions has increased alongside the development of online technology. The present study extended the findings from Griffiths’ (2012) systematic empirical review of online sex addiction by additionally investigating empirical studies that implemented and/or documented clinical treatments for online sex addiction in adults. A total of nine studies were identified and then each underwent a CONSORT evaluation. The main findings of the present review provide some evidence to suggest that some treatments (both psychological and/or pharmacological) provide positive outcomes among those experiencing difficulties with online sex addiction. Similar to Griffiths’ original review, this study recommends that further research is warranted to establish the efficacy of empirically driven treatments for online sex addiction
Interactive television quizzes as gambling: a cause for concern?
No full textRecently, there has been a significant increase in the number of UK television shows in which viewers call into the show using a premium-rate telephone service. At one level it could be argued that in these instances viewers are participating in a lottery. Viewers are typically asked to call a premium-rate telephone line to answer a simple question. Winners are then chosen from all those viewers with the correct answer. It could also be argued that the viewer is staking money (i.e., the cost of the premium-rate telephone call) on the outcome of a future event (i.e., whether they will get the correct answer). This again could be defined as a form of gambling. Interactive television quiz shows share many of the dimensions of interactive television gambling and also raise the same concerns about vulnerable and susceptible populations. These concerns are discussed
Psycholinguistic Credibility Assessment of News Reports About A 142-Year Old Mass Murder
No full textabstract: This presentation demonstrates how credibility assessment may be used on historical news and literary documents to determine the veracity of victims and witnesses even when formal statements were never made, or were lost to history. The presentation analyzes first hand accounts of the "Wickenburg Massacre" of 1871.Presented by Griffiths at the American Academy of Forensic Sciences annual meeting, February 2014 in Seattle, WA,

Identification of molecular genetic factors that influence migraine
No full textAbstract Migraine is a common neurological disorder with a strong genetic basis. However, the complex nature of the disorder has meant that few genes or susceptibility loci have been identified and replicated consistently to confirm their involvement in migraine. Approaches to genetic studies of the disorder have included analysis of the rare migraine subtype, familial hemiplegic migraine with several causal genes identified for this severe subtype. However, the exact genetic contributors to the more common migraine subtypes are still to be deciphered. Genomewide studies such as genome-wide association studies and linkage analysis as well as candidate genes studies have been employed to investigate genes involved in common migraine. Neurological, hormonal and vascular genes are all considered key factors in the pathophysiology of migraine and are a focus of many of these studies. It is clear that the influence of individual genes on the expression of this disorder will vary. Furthermore, the disorder may be dependent on gene-gene and gene-environment interactions that have not yet been considered. In addition, identifying susceptibility genes may require phenotyping methods outside of the International Classification of Headache Disorders II criteria, such as trait component analysis and latent class analysis to better define the ambit of migraine expression.Griffith Health, School of Medical ScienceNo Full Tex
