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

Strategic Fictions? John Buchan, The Times and the Ypres Salient
No full textJohn Buchan is widely known as an author of thrillers and adventure stories. His reputation as a writer of the First World War is much more limited and much more problematic. Both individually and as one of the collective of British writers who wrote in support of the nation’s wartime propaganda effort, Buchan has been subject to harsh criticism. Only recently has work by Kate Macdonald begun to trace the detail of Buchan’s war writing, which included reportage, fiction, poetry and history. As Macdonald has pointed out, Buchan’s reputation as an authority on the conflict, though high at the time, is ‘now routinely shredded’ (Macdonald 181). This chapter challenges that critical consensus, arguing that Buchan made a genuine effort to communicate the reality of the war and that he did so by use of techniques and strategies central to modern definitions of literary journalism. To condemn Buchan for the limitations of his war writing is to fail to grasp the conditions under which he worked. As John S. Bak has argued in relation to global literary journalism, ‘critiquing state-controlled presses for squashing unsavoury truths or spinning damning facts is to ignore the wider issue that, culturally speaking, we all just value truth and fact differently’ (5). The wartime valuation of truth and fact certainly differed from modern scholarly valuations. However, as Bak also suggests, the limitations imposed by war also stimulate the kind of experimentation with literary technique characteristic of literary journalism (6). Reading John Buchan’s May 1915 correspondence for The Times through the paradigm of literary journalism scholarship, this chapter argues that Buchan broke with existing journalistic traditions and experimented with literary strategies in order to connect his readers to the conflict
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,
