Problematic technology use during adolescence: why don’t teenagers seek treatment?
No full textIn recent issues of Education and Health, I have briefly reviewed the empirical evidence relating to problematic use of technology by adolescents including online video gaming (Griffiths, 2014), social networking (Griffiths, 2013a; Kuss & Griffiths, 2011), and mobile phone use (Griffiths, 2013b). Most of the research studies that have examined ‘technological addictions’ during adolescence have indicated that a small but significant minority experience severe problems resulting in detriments to education, physical fitness, psychological wellbeing, and family and personal relationships (Griffiths, 2010; Kuss, Griffiths, Karila & Billieux, 2014). Given these findings, why is it that so few teenagers seek treatment? This article briefly outlines a number of reasons why this might be the case by examining other literature on adolescent drug use and adolescent gambling (e.g., Chevalier & Griffiths, 2005; 2005; Griffiths, 2001). Three different types of explanation are discussed: (i) treatment-specific explanations, (ii) research-related explanations, and (iii) developmental and peer group explanations
Entry points and specialist qualifications in nursing
No full textSarah Robinson and Peter Griffiths explore other countries’ approaches to pre-registration nurse education. The publication of Modernising Nursing Careers in 2006 by the Department of Health recommended a review of pre-registration nurse education in the UK. The purpose of the review is to ensure that pre-registration education provides the appropriate basis for reforming the nursing careers framework, developing a competent and flexible workforce and achieving an optimum balance between specialist and generalist roles (1)....<br/

Why don't adolescents turn up for gambling treatment (revisited)?
No full textIn a previous issue of the Electronic Journal of Gambling Issues, Griffiths (2001) raised 10 speculative reasons as to why so few adolescents enrol for treatment programs when compared with adults. This paper explores the issue a little further with another 11 possible reasons. These are (i) adolescents don't seek treatment in general; (ii) adolescents may seek other forms of treatment, but gambling problems are less likely to be seen as requiring intervention; (iii) treating other underlying problems may help adolescent gambling problems; (iv) a dolescent gambling ‘bail-outs’ can mask gambling problems; (v) a ttending treatment programs may be stigmatising for adolescents; (vi) adolescents may commit suicide before getting treatment; (vii) a dolescent gamblers may be lying or distorting the truth when they fill out survey questionnaires; (viii) a dolescents may not understand what they are asked in questionnaires; (ix) screening instruments for adolescent problem gambling are being used incorrectly; (x) adolescent gambling may be socially constructed to be nonproblematic; and (xi) adolescent excesses may change too quickly to warrant treatment

Theoretical Loss and Gambling Intensity (Revisited): A Response to Braverman et al. (2013)
No full textIn this paper, we provide a brief response to Braverman and colleagues’ (2013) critique of our ‘Theoretical Loss’ metric as a measure of monetary gambling intensity (Auer & Griffiths, 2013; Auer, Schneeberger & Griffiths, 2012). We argue that ‘gambling intensity’ and ‘gambling involvement’ are essentially the same construct as descriptors of monetary gambling activity. Additionally, we acknowledge that playing duration (i.e., the amount of time – as opposed to money – actually spent gambling) is clearly another important indicator of gambling involvement – something that we have consistently noted in our previous studies including our empirical studies on gambling using behavioural tracking data. Braverman and colleagues claim that the concept of Theoretical Loss is nullified when statistical analysis focuses solely on one game type as the house edge is constant across all games. In fact, they state, the correlation between total amount wagered and Theoretical Loss is perfect. Unfortunately, this is incorrect. To disprove the claim made, we demonstrate that in sports betting (i.e., a single game type), the amount wagered does not reflect monetary gambling involvement using actual payout percentage data (based on 52,500 independent bets provided to us by an online European bookmaker). After reviewing the arguments presented by Braverman and colleagues, we are still of the view that when it comes to purely monetary measures of ‘gambling intensity’, the Theoretical Loss metric is a more robust and accurate measure than other financial proxy measures such as ‘amount wagered’ (i.e., bet size) as a measure of what players are prepared to financially risk while gambling
A Pragmatic Approach to Spearman's Rank Correlation Coefficient
No full textThis article, created by D. Griffiths, describes Spearman's coefficient of rank correlation and attempts to explain how its algebraic structure arises. The author states the goals of this lesson as, "A full understanding of correlation requires an appreciation of bivariate distributions, but increasingly rank correlation coefficients are being used as a measure of agreement with pupils for whom such appreciation is not possible. How can we justify the formula used?" The author first provides a description of the statistical method, then an example and finally a description of the mathematical formula used. This is a great introduction to this statistical method

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

Convergence of gambling and gaming: implications
No full textGaming and gambling are beginning to converge, as illustrated by the emergence of computer games where players are paid to kill other players or survive as long as possible. Professor Mark Griffiths of the International Gaming Research Unit at Nottingham Trent University, comments that as more gambling operators start to utilise gaming technology, the Gambling Commission may be forced to re-examine the exemption of such 'skill-based' games from Great Britain's Gambling Act 2005

Eiseman, ex Solidago canadensis var. hargeri, #CSE1005, CNC384785–384789 (1♂ 4♀); Nantucket Co., Nantucket, Squam Swamp, 12.vi.2013, em. 30.vi.2013, C.S. Eiseman, ex Solidago latissimifolia, #CSE630, CNC384813 (1♂). Tentatively identified material. MASSACHUSETTS: Nantucket Co., Nantucket, Ice Pond Lot, 26.vii.2014, em. 15–17.viii.2014, C.S. Eiseman, ex Solidago latissimifolia, #CSE1329, CNC384835, CNC384836 (2♀). Hosts. Asteraceae: Solidago canadensis L., S. gigantea Aiton (Griffiths 1976), S. * latissimifolia Mill.; adults tentatively assigned to this species were reared from S. flexicaulis L. (Spencer & Steyskal 1986). Leaf mine. (Fig. 179) Entirely linear, “ 6–12 cm long, remaining narrow (about 1.5 mm wide) terminally, formed entirely on upper surface of leaf, appearing white or greenish-white in reflected light when fresh; faeces deposited as fine particles, mostly forming short beaded strips; larvae leaving leaf through semicircular slit on upper surface before puparium formation” (Griffiths 1976). In some of the leaves we examined, the frass was mostly deposited in an erratic jumble of squiggly fragments, rarely appearing as straight strips for a very short stretch. Puparium. Black; formed outside the mine. Distribution. USA: *MA, WI?; Canada: AB (Griffiths 1976). Comments. Griffiths (1976) found larvae in Alberta in early August and late September, with adults emerging the following spring. He stated that this species seems to be univoltine, and that linear mines found on Solidago earlier in the season were caused by P. solidaginophaga Sehgal. In Massachusetts, P. solidaginophaga larvae were found in May, and those of P. astotinensis, Liriomyza eupatorii, and Ophiomyia maura were all found mining leaves of the same host simultaneously in mid-June. Phytomyza astotinensis is evidently at least bivoltine in Massachusetts, since an adult was reared in late June from a leaf mine collected in the same month, and larvae were found again in October. Females possibly representing P. astotinensis were also reared from larvae collected in late July, with adults emerging in mid-August.Published as part of Eiseman, Charles S. & Lonsdale, Owen, 2018, New state and host records for Agromyzidae (Diptera) in the United States, with the description of thirty new species, pp. 1-156 in Zootaxa 4479 (1) on page 69, DOI: 10.11646/zootaxa.4479.1.1, http://zenodo.org/record/145291
