A literature search was conducted using the database Web of Science.METHODS: Over the last 15 years, the number of Internet users has increased by 1000%, and at the same time, research on addictive Internet use has proliferated. Internet addiction has not yet been understood very well, and research on its etiology and natural history is still in its infancy. In 2013, the American Psychiatric Association included Internet Gaming Disorder in the appendix of the updated version of the Diagnostic and Statistical Manual for Mental Disorders(DSM-5) as condition that requires further research prior to official inclusion in the main manual, with important repercussions for research and treatment. To date, reviews have focused on clinical and treatment studies of Internet addiction and Internet Gaming Disorder. This arguably limits the analysis to a specific diagnosis of a potential disorder that has not yet been officially recognised in the Western world, rather than a comprehensive and inclusive investigation of Internet-use related addictions(including problematic Internet use) more generally. RESULTS: The systematic literature review identified a total of 46 relevant studies. The included studies used clinical samples, and focused on characteristics of treatment seekers and online addiction treatment. Four main types of clinical research studies were identified, namely research involving(1) treatment seeker characteristics;(2) psychopharmacotherapy;(3) psychological therapy; and(4) combined treatment. CONCLUSION: A consensus regarding diagnostic criteria and measures is needed to improve reliability across studies and to develop effective and efficient treatment approaches for treatment seekers.展开更多

Based upon how game design and structure may interact with personality characteristics, the current study examined the effects of hypercompetitiveness, narcissism, reward responsiveness and psychological absorption on PVGP for a group of Facebook gamers. Moreover, the present study also observed how results may differ between Facebook gamers (n = 102), and a group of other (non-Facebook) gamers (n = 132). The Facebook group comprised 84% of females with an average age of 40.39 (SD = 14.00), whereas the other group of gamers consisted of 61% of males with an average age of 24.70 (SD = 7.86). Participants completed an online survey. Structural Equation Modelling (SEM) revealed that an interaction between hypercompetitiveness and narcissism was the only significant predictor of PVGP for Facebook gamers. In contrast, a second structural model revealed that both hypercompetitiveness and psychological absorption were significant predictors of PVGP for other types of gamers. The findings from this study had important implications regarding the structure of video games and demographic differences between Facebook Gamers and other types of gamers.展开更多

There is limited literature regarding the predictors of screen media use among children. This study aimed to examine the association between selected predictors and screen media use among children aged 3 - 13. The findings of this study are based on 192 children aged 3 - 13 and their caregivers recruited from Facebook and WhatsApp groups. A descriptive cross-sectional design was employed. The participants filled a demographic questionnaire and the Problematic Media Use Measure Short Form to obtain data about parents’ and children characteristics, screen time and problematic use of media. The screen time for 83% of the children was more than two hours. Mobile ownership (beta (β) = 0.22) and conflict about mobile use (beta (β) = 0.16) have significantly predicted the child total screen time. Child age (beta (β) = 0.17) and conflict about mobile use (beta (β) = −0.33) have significantly predicted the problematic use of media. Most children in the current study exceeded the recommended screen time. There is an urgent need to implement interventions that mitigate children’s excessive use of media.展开更多

However, the sharp increase in social media usage has led to concerns about mental health and overall well-being. While social media can be valuable for staying connected with friends and being informed about the world, it can also bring about a multitude of problems, especially among the youth. This paper aims to examine available research on the relationship between social media and issues such as depression, anxiety, and cyberbullying among adolescents. Furthermore, it will explore how childhood maltreatment can affect how an individual interacts with social media. This paper not only explains how social media could have a negative effect on adolescents, with many of the aforementioned problems being linked to social media usage, but also how social media could also bring about some benefits. However, further research is needed to better understand the complexity of youth’s relationship with social media.展开更多

文摘BACKGROUND Problematic Internet use(PIU)or Internet addiction has been recognized to be a behavioral addiction characterized by excessive or poorly controlled preoccupations,urges,or behaviors regarding computer use and Internet access that leads to impairment or distress resembling substance abuse.AIM To investigate the prevalence and characteristics of Internet use and abuse in a group of drug addicts from Southern Italy,by means of a specific questionnaire[“Questionario sull’Utilizzo delle Nuove Tecnologie”(QUNT)].METHODS All subjects(183)were heavy smokers,almost 50%of them used heroin and/or opioid compounds,30%alcohol,10%cannabis,8%cocaine,and 5%were polydrug users.Almost 10%of the individuals were also suffering from gambling disorder.RESULTS The time spent online was more than 4 hours a day in the total sample,with a slight prevalence in male subjects.Cocaine and cannabis users spent more than 6 hours online,significantly more than opioid and alcohol abusers.Distribution of the QUNT factors was not different in both sexes.Cocaine users showed higher scores at the“loss of control”,“pornography addiction”,and“addiction to social networks”factors,for the stimulant effect of this substance.Moreover,15 out of the total 17 cocaine users were pathological gamblers.Positive and statistically significant relationships were observed between some QUNT factors and body mass index.CONCLUSION These findings indicate that PIU is less severe in subjects taking sedative substances,such as heroin/opioids and alcohol,than in subjects taking stimulants.Alternatively,it may be used as a“stimulant”trigger in cocaine and cannabis users.Flattening effect of abuse drugs was noted on possible sex-related differences in QUNT items.We observed a sort of“protective”effect of a love relationship and/or living together with a partner,as those engaged subjects showed lower scores on different items than single subjects or those living alone.The relationship between time spent online(and related sedentary lifestyle)and body mass index would suggest that Internet use might be a contributing factor to increasing weight gain and obesity amongst adolescents and young adults worldwide.Our findings also highlighted the specific vulnerability of drug addicts who use stimulants,rather than sedative compounds,to other kinds of behavioral addictions,such as gambling disorder.
文摘The current study used the structural components of Facebook games to select predictors of Problematic Video Game Play (PVGP) in relation to Facebook games. Based upon how game design and structure may interact with personality characteristics, the current study examined the effects of hypercompetitiveness, narcissism, reward responsiveness and psychological absorption on PVGP for a group of Facebook gamers. Moreover, the present study also observed how results may differ between Facebook gamers (n = 102), and a group of other (non-Facebook) gamers (n = 132). The Facebook group comprised 84% of females with an average age of 40.39 (SD = 14.00), whereas the other group of gamers consisted of 61% of males with an average age of 24.70 (SD = 7.86). Participants completed an online survey. Structural Equation Modelling (SEM) revealed that an interaction between hypercompetitiveness and narcissism was the only significant predictor of PVGP for Facebook gamers. In contrast, a second structural model revealed that both hypercompetitiveness and psychological absorption were significant predictors of PVGP for other types of gamers.

文摘Fear of missing out(FoMO)is a unique term introduced in 2004 to describe a phenomenon observed on social networking sites.FoMO includes two processes;firstly,perception of missing out,followed up with a compulsive behavior to maintain these social connections.We are interested in understanding the complex construct of FoMO and its relations to the need to belong and form stable interpersonal relationships.It is associated with a range of negative life experiences and feelings,due to it being considered a problematic attachment to social media.We have provided a general review of the literature and have summarized the findings in relation to mental health,social functioning,sleep,academic performance and productivity,neuro-developmental disorders,and physical well-being.We have also discussed the treatment options available for FoMo based on cognitive behavior therapy.It imperative that new findings on FoMO are communicated to the clinical community as it has diagnostic implications and could be a confounding variable in those who do not respond to treatment as usual.
文摘This paper presents the results from a case study highlighting the difficulties of pile driving in diatomaceous soils.In the companion(first)paper to this article,results of an extensive laboratory and in situ testing program were presented while the results from pile driving and further analysis of field observations were presented herein.Unexpected high pile rebound(HPR)was observed during driving of a closed-end pipe pile,with refusal occurring at a depth of less than 5 m.Subsequent open-ended piles were thus driven.Piezometer and case pile wave analysis program(CAPWAP)data were collected during driving of both closed-and open-end piles.Piezometer data indicated that negative pore water pressures(PWPs)were generated while the closed-ended pile exhibited high rebound.Results from in situ tests indicated change in material stiffness and strong dilative tendencies near the depth of refusal.A hypothesis for observed behavior was proposed that considers the soil beneath the pile as a medium with an effectively infinite bulk modulus.
文摘To the editor The present problematic outbreak in Africa is the Ebola virus infection among local population in the capital of Guinea.It becomes a great concern since the present outbreak(March to April 2014)is considered to be the biggest outbreak,the first discovery of this viral infection[1].A high death rate can be seen.Severe diarrhea and bleeding can be seen in almost all cases and death rate is very high(about 75%).Focusing on the present outbreak,there are many considerations on this situation.First,this outbreak occurs in urban area insead of a remote rural area。

文摘Diatomaceous soils are comprised of the silica frustules of diatom microalgae that are present in marine and lacustrine environments throughout the world.Owing to their unique origin,diatomaceous soils are typically characterized by high intraparticle porosity,complex particle shapes,and uniform mineralogy,causing them to exhibit atypical physical and engineering behaviors.A substantial deposit of diatomaceous silt was observed during site exploration for construction of the Buck Creek Bridge on OR140 near Klamath Falls,OR,USA.A comprehensive laboratory and in situ testing program indicated that the diatomaceous soil possessed“non-textbook”engineering properties.Specifically,tested samples had high liquid limits(≈100%-140%)with natural water contents at or near the liquid limit.Geologically,the soil is expected to be normally consolidated,yet high apparent overconsolidation ratios(OCR)(≈15-40)were observed both in oedometric consolidation tests and through cone penetration test(CPT)correlations.Standard penetration test(SPT)results show a corrected standard penetration resistance consistent with a medium-dense sand(i.e.(N1)_(60)≈25).CPT results include corrected tip resistances(qt)of approximately 7-10 MPa and excess pore pressures(u_(2))of up to 4 MPa.In CPT dissipation tests,pore water pressures(PWPs)returned to hydrostatic pressure in less than 1 h.In this work,we synthesize these seemingly disparate material properties in an attempt to infer appropriate engineering properties for the diatomaceous deposit at the Buck Creek Bridge and attempt to provide insight into the underlying reasons for the observed behavior.
文摘To the editor,Sir,the present problematic Ebola virus(HBOV)infectionin Africa is the global concern.The pathogenesis and hostresponse to the EBOV infection is the interesting topic.
文摘To the editor,Ebola virus infection is the new deadly viral infection that is presently problematic in many countries in Africa.The prevention of this disease seems to be difficult and the rapid distribution of disease becomes the important issue for further discussion.As noted by Muyembe-Tamfum et al.[1],one of the major disease control measures is the distribution of protective equipment to health care workers.Gloves are important protective equipments
