The present study examines the relationship between social Internet use and loneliness and reviews the studies about this topic from both social psychology and computer-mediated communication literature, as a response to the call for interdisciplinary research from scholars in these two areas. Two hundred thirty-four people participated in both the survey testing trait loneliness and a 5-condition (face-to-face chatting, instant message chatting, watching video, writing assignments, and "do nothing") experiment. Participants reported increase of mood loneliness after chatting online. The level of mood loneliness after online chat was higher than that in face-to-face communication. For people with high trait loneliness, the mood loneliness increase in the computer-mediated communication condition was significantly higher than in the face-to-face communication condition. The author of the current study hopes to help clarify the mixed research findings in previous social Internet use literature about this topic and reminds communication researchers of the need to explore the constructs included in "psychological well-being" in terms of their nature, mechanism, causes, consequences, and furthermore, how they are related to communication.

Learners’ Participation in Informal Japanese-English Internet Chat

2009-12-01

Full Text Available It has been widely claimed that computer mediated communication offers unique opportunities for language learners, including the ability to take on the roles of ‘writer’ and ‘reader’, ‘teacher’ and ‘learner’. Hence, it is important for teachers and learners to be aware of not only the linguistic and interactional characteristics of especially bilingual chat, but also how participants in an intercultural setting may switch between roles. Learning about one’s second language from a peer, and in turn, teaching that peer about one’s native language may allow both participants opportunities to develop as language experts.This article utilises naturalistic bilingual chat data and follow-up interviews to examine the implications of these findings for learners, teachers and researchers.

Crisis support services have historically been offered by phone-based suicide prevention hotlines, but are increasingly becoming available through alternative modalities, including Internet chat and text messaging. To better understand differences in the use of phone and chat/text services. We conducted semistructured interviews with call responders at the Veterans Crisis Line who utilize multimodal methods to respond to veterans in crisis. Responders indicated that veterans may access the chat/text service primarily for reasons that included a desire for anonymity and possible inability to use the phone. Responders were divided on whether callers and chatters presented with different issues or risk of suicide; however, they suggested that veterans frequently use chat/text to make their first contact with mental health services. We spoke with call responders, not the veterans themselves. Additionally, as this is qualitative research, applicability to other settings may be limited. While new platforms offer promise, participants also indicated that chat services can supplement phone lines, but not replace them.

JNC is doing publicity work to let the technical reliability for geological disposal of high-level radioactive waste (HLW) comprehended widely. But the information about geological disposal of HLW itself and its technology has not been spread and recognized. It has been required to offer the opportunity to discuss the geological disposal and its technology as our own issue. Recently the internet, which has such characteristics as two-way, instant and open communication means, has become used on business and for pleasure commonly. So the opportunity for discussing the topics related to geological disposal of HLW has been offered on the internet web site so-called 'Internet Forum' by JNC since fiscal year 1999. 'Internet Forum' or an assembly of chat rooms is being run on the web server which is not operated by JNC in order to provide the place where discussion on the issue can be done as fairly and objectively as possible. In this report, the results of Internet Forum in fiscal year 2000 comparing with that in fiscal year 1999 were shown and the adequate approaches of operating 'Internet Forum' and offering the information about geological disposal of HLW were reviewed.

Gilat, Itzhak; Shahar, Golan

2007-01-01

The telephone and the internet have become popular sources of psychological help in various types of distress, including a suicide crisis. To gain more insight into the unique features of these media, we compared characteristics of calls to three technologically mediated sources of help that are part of the volunteer-based Israeli Association for Emotional First Aid (ERAN): Telephonic hotline (n = 4426), personal chat (n = 373) and an asynchronous online support group (n = 954). Threats of suicide were much more frequent among participants in the asynchronous support group than the telephone and personal chat. These findings encourage further research into suicide-related interpersonal exchanges in asynchronous online support groups.

Young people in Canada prefer to use the Internet over face-to-face contact when seeking help for problems of daily living and mental health problems. Kids Help Phone (KHP) provides on-demand, anonymous help to young people via telephone and Live Chat technologies. Two hundred thirty-two phone clients and 230 Live Chat clients responded to a questionnaire at this otherwise anonymous service, providing previously inaccessible data about their individual characteristics and characterizations of the problems for which they sought help. There was a larger proportion of weighty problems (mental health and suicide) among chatters than callers. There were also more non-heterosexual youth, and those who identified as Asian and Black African or Caribbean, using Live Chat than phone. Implications for training Live Chat counsellors to respond effectively to chatters are discussed.

Alert: the dark side of chats--internet without boundaries.

Aderet, Avshalom

2009-01-01

The web has some unique advantages: It eliminates barriers of space and time; information flows quicker and is more accessible to all; the markets are more effective; community and interpersonal communication is more evolved. However, the web is also anonymous, without supervision, freedom of speech is exploited, minors and other web users are exploited, racism and prejudice are encouraged. These manifestations of violence not only hurt many people but actually pose a threat to the existence of the web as a place for exchanging ideas and thoughts, as a tool for relaying messages in a liberal and democratic fashion. Today, it is not legally possible to stop any discussion group or chats, like the one in which Eran participated, which develop dialogues regarding death or suicide. A wise and proper use of the web will be achieved by agreements and not enforcement. It is a process of education in its widest meaning that will be accomplished through the acceptance of norms. Proper use of the web will be possible when all sides--users, site owners and suppliers--willingly commit to values of mutual respect, decency and protection of individual fundamental rights to freedom. The web, which is a great blessing to the communication between people, organizations and cultures, carries with it substantial risks, especially to young users. The rapid expansion of the web and the increase in the number of users has brought many social-ideological dangers alongside the many advantages. In order to deal with these issues, a few years ago I initiated an association known as Eshnav (www.eshnav.org.il) which acts to increase public awareness to the risks and dangers of the web. Eshnav's mission, established to commemorate Eran's memory, is to promote public awareness to the positive and negative aspects of using the web on society and its values, and to promote the wise and safe use of the web. Eran was in great distress and needed empathy, encouragement and support. Sadly, when his

The Current Status and a New Approach for Chinese Doctors to Obtain Medical Knowledge Using Social Media: A Study of WeChat

Full Text Available Background. WeChat is the most widely and frequently used mobile social media in China and has profoundly integrated into the daily life of many Chinese people. A variety of medicine-related information may be found on WeChat. As users of WeChat, doctors often access health-related information and even provide a variety of medical services or participate in various types of mobile communication with patients. Objective. This study is the first attempt to quantitatively explore the approaches by doctors of acquiring medical knowledge using Internet resources especially social media such as WeChat to access knowledge. Methods. A self-administered questionnaire was designed, distributed, collected, and analyzed utilizing the online survey tool Sojump. WeChat was adopted to randomly release the questionnaires using snowball sampling and collect the results after a certain amount of time. Results. 292 valid questionnaires out of 314 questionnaires by clinical doctors were analyzed. Regarding the current status of accessing medical knowledge among doctors, more than 60% of the doctors regularly used the Internet to search for medical knowledge, 19.86% used WeChat as a channel to acquire medical knowledge, and only 23.97% were satisfied with acquiring medical knowledge through the Internet. Regarding the frequency of WeChat usage, nearly 40% of the doctors accessed WeChat more than 20 times per day and over 70% used WeChat for over half an hour every day. Regarding the status of accessing medical knowledge through WeChat, nearly half (47.26% of the doctors stated that they often read professional medical articles on WeChat and the most common channel is friends’ moment sharing and public account subscriptions, with selection rates of 59.93% and 60.27%, respectively. The most desirable mode of acquiring medical knowledge through WeChat was the following: “professional medical knowledge from peers, with a reminder.” Conclusion. WeChat has become a

Twitter Chats as a Research Tool: A Study of Young Adult Financial Decisions

Directory of Open Access Journals (Sweden)

Barbara O’Neill

2018-02-01

Full Text Available Many researchers collect online survey data because it is cost-effective and less time-consuming than traditional research methods. This paper describes Twitter chats as a research tool vis-à-vis two other online research methods: providing links to electronic surveys to respondents and use of commercially available survey panels through vendors with readily available respondents. Similar to a face-to-face focus group, Twitter chats provide a synchronous environment for participants to answer a structured series of questions and to respond to both the chat facilitator and each other. This paper also reports representative responses from a Twitter chat that explored financial decisions of young adults. The chat was sponsored by a multi-state group of land-grant university researchers, in cooperation with WiseBread, a personal finance website targeted to millennials, to recruit respondents for a more extensive month-long online survey about the financial decisions of young adults. The Twitter chat responses suggest that student loans were the top concern of participants, and debt and housing rounded out the top three concerns. The internet, both websites and social media, was the most frequently cited source of financial information. The article concludes with a discussion of lessons learned from the Twitter chat experience and suggestions for professional practice.

These days young people use internet as a source of information. Internet offers knowledge that can be used not only for school education but also to obtain information about usage and effects of psychoactive substances. Recent research shows that young people more often use internet websites and chat rooms to exchange knowledge and experience with chemicals and everyday products used as intoxicants, for example: nutmeg, nonprescription medications, metal cleaning liquid or feminine hygiene products. This article shows the extend of knowledge young people can gain from popular internet websites. Information on the web is presented as appealing, attractive and encouraging. From a toxicologist point of view it is extremely important to be familiar with those new threats because more and more often we have to treat young patients with a serious poisoning from usage of experimental intoxicating substances.

Garas, Antonios; Garcia, David; Skowron, Marcin; Schweitzer, Frank

2012-05-01

How do users behave in online chatrooms, where they instantaneously read and write posts? We analyzed about 2.5 million posts covering various topics in Internet relay channels, and found that user activity patterns follow known power-law and stretched exponential distributions, indicating that online chat activity is not different from other forms of communication. Analysing the emotional expressions (positive, negative, neutral) of users, we revealed a remarkable persistence both for individual users and channels. I.e. despite their anonymity, users tend to follow social norms in repeated interactions in online chats, which results in a specific emotional ``tone'' of the channels. We provide an agent-based model of emotional interaction, which recovers qualitatively both the activity patterns in chatrooms and the emotional persistence of users and channels. While our assumptions about agent's emotional expressions are rooted in psychology, the model allows to test different hypothesis regarding their emotional impact in online communication.

When do online sexual fantasies become reality? The contribution of erotic chatting via the Internet to sexual risk-taking in gay and other men who have sex with men.

Science.gov (United States)

Adam, Philippe C G; Murphy, Dean A; de Wit, John B F

2011-06-01

Seeking sexual partners online is associated with sexual risk-taking among men who have sex with men (MSM), but it is not well understood how this use of the Internet is implicated in potential sexual risks. The present study explores whether fantasizing about unprotected anal intercourse (UAI) during online chatting is associated with UAI with partners met online. An online survey of 2058 MSM in France included assessments of UAI with partners met online, responses to erotic chatting about UAI, intentions to use condoms, attitudes regarding UAI, practicing UAI with casual partners, alcohol and drug use with sex and biographical characteristics. While intentions to use condoms with casual partners were high, one-third (32.1%) of respondents reported UAI with partners met online. Responding positively to online chatting about UAI was significantly associated with UAI with partners met online, controlling for intentions, attitudes, behavior and biographic characteristics. These findings suggest that, while MSM may not go online to seek UAI, some engage in online fantasizing about UAI that is associated with possible sexual risk-taking. This speaks critically to the assumption that online fantasizing has no behavioral implications, and underscores the importance of human immunodeficiency virus prevention that addresses the dynamics of online chatting.

Rosenkranz, Tabea; Müller, Kai W; Dreier, Michael; Beutel, Manfred E; Wölfling, Klaus

2017-01-01

This paper examines the addictive potential of 8 different Internet applications, distinguishing male and female users. Moreover, differential correlates of problematic use are investigated in Internet gamers (IG) and generalized Internet users (GIU). In a representative sample of 5,667 adolescents aged 12-19 years, use of Internet applications, problematic Internet use, psychopathologic symptoms (emotional problems, hyperactivity/inattention, and psychosomatic complaints), personality (conscientiousness and extraversion), psychosocial correlates (perceived stress and self-efficacy), and coping strategies were assessed. The addictive potential of Internet applications was examined in boys and girls using regression analysis. MANOVAs were conducted to examine differential correlates of problematic Internet use between IG and GIU. Chatting and social networking most strongly predicted problematic Internet use in girls, while gaming was the strongest predictor in boys. Problematic IG exhibited multiple psychosocial problems compared to non-problematic IG. In problematic Internet users, GIU reported even higher psychosocial burden and displayed dysfunctional coping strategies more frequently than gamers. The results extend previous findings on the addictive potential of Internet applications and validate the proposed distinction between specific and generalized problematic Internet use. In addition to Internet gaming disorder, future studies should also focus on other highly addictive Internet applications, that is, chatting or social networking, regarding differential correlates of problematic use. © 2017 S.

Second Language Socialization in a Bilingual Chat Room: Global and Local Considerations

Directory of Open Access Journals (Sweden)

Wan Shun Eva Lam

2004-09-01

Full Text Available This paper considers how global practices of English on the Internet intersect with local practices of English in the territorial or national sphere in constructing the language experiences of immigrant learners. Using a multi-contextual approach to language socialization, this paper examines the social and discursive practices in a Chinese/English bilingual chat room and how this Internet chat room provides an additional context of language socialization for two teenage Chinese immigrants in the US. Analysis of discourse, interview, and observational data reveals that a mixed-code variety of English is adopted and developed among the focal youth and their peers around the globe to construct their relationships as bilingual speakers of English and Cantonese. This language variety served to create a collective ethnic identity for these young people and allowed the girls to assume a new identity in speaking English that doesn't follow the social categories of English-speaking Americans versus Cantonese-speaking Chinese in their local American context. This paper makes the case for studying how people navigate across contexts of socialization in the locality of the nation-state and the virtual environments of the Internet to articulate new ways of using English.

Possuindo interfaces supostamente intuitivas (salas de bate-papo em web, proporcionam, em tese, um meio fácil de usar e potencialmente rico para fins educacionais. Para testar esse meio, uma sessão de chat foi realizada com fins acadêmicos por estudantes e professores de uma disciplina de pós-graduação. Com seus propósitos aparentemente frustrados, essa sessão foi estudada sob instrumentais teórico-metodológicos diversos, no intuito de analisar, de diferentes ângulos, os obstáculos ao uso educacional do chat e sugerir algumas soluções. Com base nos turnos registrados pela ferramenta, foram analisadas as relações interpessoais e as dificuldades no ritmo da conversação; interações e dificuldades relativas a assimetrias, domínios e desenvolvimento de tópicos; fases da construção de conhecimento, e dificuldades técnico-operacionais. Entre os resultados convergentes das diversas análises, demonstrou-se principalmente o impacto da experiência prévia de uso da ferramenta para o sucesso do uso educacional do chat na evolução dos tópicos, no ritmo da conversação e nos domínios interacionais; também constatou-se o impacto do papel do professor e da experiência prévia nas fases de construção do conhecimento identificadas nos turnos dos alunos. Esses resultados sugerem que, para o chat ser proveitoso do ponto de vista educacional, é necessária uma preparação prévia cuidadosa. Para que a ferramenta possa ser mediadora de aprendizagem, é necessário evitar digressões, manter uma pequena variedade de tópicos e, portanto, um foco mais definido no tema programado para a discussão. Igualmente cuidadosa deve ser a mediação do professor para incentivar as problematizações e as sínteses, além de garantir, mediante o apoio aos turnos dos alunos menos experientes

To analyze and compare Modified Checklist for Autism in Toddlers (M-CHAT) and Checklist for Autism in Toddlers-23 (CHAT-23) in terms of clinical applicability, and to provide a basis for the understanding of early specific clinical manifestations of children with autism. A total of 350 children aged 18-36 months who visited the Department of Developmental Pediatrics of Shengjing Hospital of China Medical University were enrolled as subjects. Of the 350 children, 284 who had not been previously diagnosed with autism were screened according to the two checklists. Sixty-eight confirmed cases of autism (including two of the 284 screening subjects diagnosed with autism) were assigned to the autism group, and 278 of the 284 screening subjects (except six children diagnosed with autism, mental retardation or cerebral palsy) were assigned to the control group. The two groups were compared with respect to the positive rate for each item in the checklists. The efficacy of the M-CHAT and CHAT-23 assessment criteria was evaluated by comparative analysis. The autism group showed the highest positive rate for Item 9. There were significant differences between the two groups in terms of the positive rates for all items except Item 16 (PCHAT showed the lowest rate of missed diagnosis (0%); when the assessment criterion was that autism was confirmed if there were positive results for at least 6 of a total of 23 items, CHAT-23 showed the lowest rate of misdiagnosis (1.77%). The specificity of M-CHAT is lower than that of CHAT-23 (P0.05). CHAT-23 is more suitable than M-CHAT for clinical autism screening due to higher specificity, as well as having the advantages of low cost, easy completion,high efficiency and easy result judgment.

Recorded peer video chat as a research and development tool

When practising teachers take time to exchange their experiences and reflect on their teaching realities as critical friends, they add meaning and depth to educational research.

Schmiedl, S; Geishauser, M; Klöppel, M; Biemer, E

1998-01-01

Today, the exchange of information in the Internet is dominated by the WWW and e-mail. Discussion groups like mailing lists and newsgroups also permit communication in groups. Information retrieval becomes a crucial challenge in using the Internet. In the field of medicine, three more aspects are of special importance: privacy, legal requirements, and the necessity of transferring large amounts of data. For these problems, today's Internet doesn't provide a sufficient solution yet. Future developments will not only improve the existing services, but also lead to fundamental changes in the transfer technologies: Safer data transfer is to be ensured by new encrypting software together with the planned transfer protocol IPv6. Introducing the new transfer mode ATM will lead to better and resource saving transmission. Computer, telephone and TV networks will grow together, resulting in convergence of media.

[Internet addiction].

Korkeila, Jyrki

2012-01-01

Internet addiction is defined as uncontrolled and harmful use of Internet, which manifests in three forms: gaming, various sexual activities and excessive use of emails, chats or SMS messaging. Several studies have found that abuse of alcohol and other substances, depression and other health problems are associated with Internet addiction. In boys and men depression may be more a consequence of the addiction than a cause for it. ADHD seems to be a significant background factor for developing the condition. Because it is almost impossible to lead a life without Internet and computers nowadays, it is unrealistic to aim towards full abstinence. Treatment has generally followed the guidelines adapted for pathological gambling.

Marziali, Elsa; Garcia, Linda J

2011-02-01

The aim of this study was to examine the impact on dementia caregivers' experienced stress and health status of 2 Internet-based intervention programs. Ninety-one dementia caregivers were given the choice of being involved in either an Internet-based chat support group or an Internet-based video conferencing support group. Pre-post outcome measures focused on distress, health status, social support, and service utilization. In contrast to the Chat Group, the Video Group showed significantly greater improvement in mental health status. Also, for the Video Group, improvements in self-efficacy, neuroticism, and social support were associated with lower stress response to coping with the care recipient's cognitive impairment and decline in function. The results show that, of 2 Internet-based intervention programs for dementia caregivers, the video conferencing intervention program was more effective in improving mental health status and improvement in personal characteristics were associated with lower caregiver stress response.

"What exactly is a paedophile?" Children talking about Internet risk

Directory of Open Access Journals (Sweden)

Andrew Burn

2017-09-01

Full Text Available Reports tell us that the internet is opening new dangers to children, including online grooming, exposure to pornography and financial scams (Carr 2004; Gardner 2003; UK Home Office 2001; O'Connell 2003. The result has been various initiatives which attempt to teach children safe surfing habits. The UK Home Office "ThinkUKnow" campaign featured advertisements on the radio, internet and cinemas, targeting teens and preteens with the message that the person they are chatting to "may not be who you think they are". There are indications that such campaigns have had an impact on children's awareness of "stranger danger" on the internet (Livingstone/Bober 2003. However, many organisations are still struggling with the question of how best to prevent internet-related harm to children. Children are exposed not only to advertising campaigns about stranger danger but also sensationalist stories about, for example, what happens to girls who enter chat rooms. When a teenage girl goes missing, police investigations routinely include looking at the girls' online activities, and tabloid media frequently make the connection between missing school girls and chat room activities. These connections are firmly embedded in the minds of the children we interviewed for the study we will be discussing. Alongside the very rational and prohibitive discourse coming from campaigns which warn children against any chat with strangers, sit the folkloric stories about girls meeting up and getting killed by paedophiles. The challenge to educators is to find an approach which will engage with both sets of discourses.

Identity and intimacy crises and their relationship to internet dependence among college students.

Huang, Ya-Rong

2006-10-01

In an attempt to test Kandell's proposition that internet dependents used the internet as a coping mechanism against underlying psychological issues, this study investigated the extent to which the fifth and sixth Eriksonian crises (identity, intimacy), were related to internet dependence (online chatting, gaming) among college students. Students spending more than 10 hours per week on chatting/gaming were classified as dependents. On the basis of a national sample of freshmen in Taiwan, this study found that the dependents scored significantly lower on most of the measures that reflected the successful resolution of the crises, and higher on the measures that reflected unsuccessful resolution of the crises. Kandell's proposition was supported.

Internet use by the socially fearful: addiction or therapy?

Campbell, Andrew J; Cumming, Steven R; Hughes, Ian

2006-02-01

The Internet has often been argued to have adverse psychological consequences, such as depression or anxiety symptoms, among "over-users." The present study offers an alternative understanding, suggesting the Internet may be used as a forum for expanding social networks and consequently enhancing the chance of meaningful relationships, self-confidence, social abilities, and social support. An online sample of 188 people was recruited over the Internet, while paper and pencil tests were administered to an offline sample group of 27 undergraduate university students, who were regular Internet users. Subjects completed the Zung Depression Scale (ZDS), Depression, Anxiety and Stress Scales (DASS), Eysenck Personality Questionnaire?Revised Short Scale (EPQ-R Short), Fear of Negative Evaluation (FNE) scale, Internet Use Questionnaire (IUQ), and an Internet Effects Questionnaire (IEQ). Results suggested that there was no relationship between time spent online and depression, anxiety, or social fearfulness. Those who primarily used the Internet for online chat believed that the Internet is psychologically beneficial to them, but also believed that frequent Internet users are lonely and that the Internet can be addictive. It is argued that "chat" users who are socially fearful may be using the Internet as a form of low-risk social approach and an opportunity to rehearse social behavior and communication skills, which, may help them improve interaction with offline, face-to-face, social environments.

Internet Sexualities

Science.gov (United States)

Döring, Nicola

The term “internet sexuality” (or OSA, online sexual activities) refers to sexual-related content and activities observable on the internet (cf. Adams, Oye, & Parker, 2003; Cooper, McLoughlin, & Campbell, 2000; Leiblum & Döring, 2002). It designates a variety of sexual phenomena (e.g., pornography, sex education, sexual contacts) related to a wide spectrum of online services and applications (e.g., websites, online chat rooms, peer-to-peer networks). If an even broader range of computer networks - such as the Usenet or bulletin board systems - is included in this extensional definition, one speaks of “online sexuality” or “cybersexuality.”

2016-01-01

Full Text Available Since WeChat has been launched in 2011, as of the first quarter of 2015, the active users have reached 549 million per month1. WeChat has become the largest mobile instant messaging software among the user groups in Asia. Therefore, WeChat is no longer “micro”, and grabs the attention of more youth groups by virtue of the “micro” advantages in the Internet era in a way of low-priced new media. Through sorting 192 effective questionnaires recovered, this paper summarizes some transmitting tendency and suggestions of “micro” innovation diffusion from the research view of the concept of innovation diffusion theory, and development stage of WeChat in the youth group, based on the survey data and by the use of the statistics of informatics, qualitative and quantitative analysis method, so as to provide a certain theoretical basis for the future research of WeChat.

2018-05-01

To examine the association between adolescent leisure-time Internet use and social integration in the school context and how this association affects later depressive symptoms among adolescents in Taiwan, using a large nationwide cohort study and the latent growth model (LGM) method. Data of 3795 students followed from the year 2001 to 2006 in the Taiwan Education Panel Survey were analyzed. Leisure-time Internet use was defined by the hours per week spent on (1) online chatting and (2) online games. School social integration and depressive symptoms were self-reported. We first used an unconditional LGM to estimate the baseline (intercept) and growth (slope) of Internet use. Next, another LGM conditioned with school social integration and depression was conducted. Approximately 10% of the participants reported engaging in online chatting and/or gaming for more than 20 hours per week. Internet use for online chatting showed an increase over time. School social integration was associated with the baseline amount (coefficient = -0.62, p < 0.001) but not the growth of leisure-time Internet use. The trend of Internet use was positively related to depressive symptoms (coefficient = 0.31, p < 0.05) at Wave 4. School social integration was initially associated with decreased leisure-time Internet use among adolescents. The growth of Internet use with time was not explainable by school social integration but had adverse impacts on depression. Reinforcing adolescents' bonding to school may prevent initial leisure-time Internet use. When advising on adolescent Internet use, health care providers should consider their patients' social networks and mental well-being.

Biochemistry and cellular biology courses for medical students at Tongji University include the assessment that provides students with feedback to enhance their learning, which is a type of formative assessment. However, frequent instant feedback and guidance for students is often absent or inconsistently included in the teaching process. WeChat, the most popular Chinese social media, was introduced in biochemistry and cellular biology course. A WeChat official account (OA) was set up as an instant interactive platform. Over a period of two semesters, OA sent 73 push notifications. The components included course notices, preclass thought questions, after-class study materials, answer questions and feedback, simulation exercises, teacher-student interaction, and research progress relevant to the course. WeChat OA served as an active-learning teaching tool, provided more frequent feedback and guidance to students, and facilitated better student-centered communication in the teaching process. Using the WeChat OA in medical teaching emphasized interactive, interoperable, effective, engaging, adaptable, and more participatory teaching styles. As a new platform, WeChat OA was free, Internet-reliant, and easily managed. Using this new medium as a communication tool accelerated further advancement of instant feedback and improvement in teaching activities. Notifications and interactive feedback via the mobile social medium WeChat OA anytime and anywhere facilitated a student-centered teaching mode. Use of WeChat OA significantly increased the proportion of students interactively participating and resulted in a high degree of student satisfaction. © 2017 by The International Union of Biochemistry and Molecular Biology, 45(5):421-425, 2017. © 2017 The International Union of Biochemistry and Molecular Biology.

The Internet, the largest network of connected computers, provides immediate, dynamic, and downloadable information. By re-architecturing the work place and becoming familiar with Internet resources, pediatric surgeons have anticipated the informatics capabilities of this computer-based technology creating a new vision of work and organization in such areas as patient care, teaching, and research. This review aims to highlight how Internet navigational technology can be a useful educational resource in pediatric surgery, examines web pages of interest, and defines ideas of network communication. Basic Internet resources are electronic mail, discussion groups, file transfer, and the Worldwide Web (WWW). Electronic mailing is the most useful resource extending the avenue of learning to an international audience through news or list-servers groups. Pediatric Surgery List Server, the most popular discussion group, is a constant forum for exchange of ideas, difficult cases, consensus on management, and development of our specialty. The WWW provides an all-in-one medium of text, image, sound, and video. Associations, departments, educational sites, organizations, peer-reviewed scientific journals and Medline database web pages of prime interest to pediatric surgeons have been developing at an amazing pace. Future developments of technological advance nurturing our specialty will consist of online journals, telemedicine, international chatting, computer-based training for surgical education, and centralization of cyberspace information into database search sites.

Social communication is one of the most common reasons for using the Internet. This paper examines how the personality characteristics of the user affect the meaning and importance of Internet social interaction in comparison with "real life," face-to-face interactions. Forty subjects all of whom were familiar with using "chat" participated in this study. After a at" session, they were instructed to answer several questionnaires. It was found that introverted and neurotic people locate their "real me" on the Internet, while extroverts and nonneurotic people locate their "real me" through traditional social interaction. The implications of our results for understanding the user-net interaction, the "real-me" location, extroversion, neuroticism, and Internet interaction, and the treatment of social phobics are examined.

Kandari, Laxman S; Yadav, Hiranmai R; Thakur, Ashok K; Kandari, Tripti

2014-01-01

Chat (Catha edulis) is an important perennial crop and its leaves are chewed for a stimulating effect. It is widely cultivated in the Ethiopian highlands of Oromia region and is figured as Ethiopia's second largest foreign exchange earner. Its cultivation accounts for about 70% of farmer's income in the study area. The common effect of its consumption leads to insomnia, a condition that the users sometimes try to overcome with sedatives or alcohol. The present study is an attempt to survey and assess the impact of crop on the community. It has been observed to implicate health problems, reduces savings and nutritional standards of the family members. The chat yields in the area ranges from 1500-1800 kg/ha through monoculture. During the study, the average monthly income of the family practicing chat cultivation was from Birr 8, 533.00 to 13, 166.00 kg/ha per year in Baate and Genede cultivating areas. When the average cost per/ha was rupees 60/kg. The present study shows that during the recent past, leaf consumption has increased significantly. Chat growers are not only producers but also traders and consumers. Its consumption has become a widespread habit from secondary schools. Highest number of consumers was found to be among drivers followed by students and shopkeepers. The consumption of the plant is not considered a taboo but on contrary a status symbol in the region. It has no legal or moral implications and is considered as a part of custom and habit of local people. High value cash crop like vegetables and orchard fruits needs to be used as a replacement for chat which could be a regular source of income to farmers. Alternative sources of income for farmers needs to be scientifically worked out and proposed keeping in view the proportion of agricultural land reserved under chat cultivation and to increase the production of food grains being produced.

Advances in Internet technology now enable unprecedented global collaboration and collective knowledge exchange. Up to this time, there have been limited efforts to use these technologies to actively promote knowledge exchange across the global pediatric critical care community. To develop an open-access, peer-reviewed, not-for-profit Internet-based learning application, OPENPediatrics, a collaborative effort with the World Federation of Pediatric Intensive and Critical Care Societies, was designed to promote postgraduate educational knowledge exchange for physicians, nurses, and others caring for critically ill children worldwide. Description of program development. International multicenter tertiary pediatric critical care units across six continents. Multidisciplinary pediatric critical care providers. A software application, providing information on demand, curricular pathways, and videoconferencing, downloaded to a local computer. In 2010, a survey assessing postgraduate educational needs was distributed through World Federation of Pediatric Intensive and Critical Care Societies to constituent societies. Four hundred and twenty-nine critical care providers from 49 countries responded to the single e-mail survey request. Respondents included 68% physicians and 28% nurses who care for critically ill children. Fifty-two percent of respondents reported accessing the Internet at least weekly to obtain professional educational information. The five highest requests were for educational content on respiratory care [mechanical ventilation] (48% [38%]), sepsis (28%), neurology (25%), cardiology (14%), extracorporeal membrane oxygenation (10%), and ethics (8%). Based on these findings, and in collaboration with researchers in adult learning and online courseware, an application was developed and is currently being used by 770 registered users in 60 countries.

2016-12-01

The purpose of this study was to determine Turkish university students' uses of and attitudes toward the Internet concerning sexuality. The study was conducted in two public universities in the Central Anatolia and Eastern Anatolia regions of Turkey. Among the students invited to take part in the study, 1,330 students agreed to do so. The study data were collected using a questionnaire designed by researchers to determine participants' personal characteristics, computer and Internet uses in general, and for sexual matters. The findings suggest that approximately half of the students (51%) reported using the Internet to obtain information about sexuality. Among the students, 30.5% said that they visit erotic and pornographic Web sites, 21.1% said that they chat on the Internet about sexuality, and 9.3% said that they bought sexual products online. Compared to the female students, the male students, statistically, more frequently show behaviors such as obtaining sexual information on the Internet, online sexual shopping, chatting on the Internet about sexuality, and visiting pornographic and erotic Web sites. In addition, female students have more negative attitudes toward using the Internet for sexual purposes. This study discusses its results along with the literature from Turkey and other countries.

Increasing research on Internet addiction makes it necessary to distinguish between the medium of Internet and its specific applications. This study explores the relationship between time spent on various Internet applications (including online gaming) and Compulsive Internet Use in a large sample of adolescents. The 2007 (N=4,920) and 2008 (N=4,753) samples of a longitudinal survey study among adolescents were used, as well as the 2007-2008 cohort subsample (N=1421). Compulsive Internet Use was predicted from the time spent on the various Internet applications in two cross-sectional multiple linear regression models and one longitudinal regression model in which changes in behavior were related to changes in Compulsive Internet Use. In both samples, downloading, social networking, MSN use, Habbo Hotel, chatting, blogging, online games, and casual games were shown to be associated with Compulsive Internet Use. Off these, online gaming was shown to have the strongest association with Compulsive Internet Use. Moreover, changes in online gaming were most strongly associated with changes in Compulsive Internet Use over time for the longitudinal cohort. A clear relationship was shown between online gaming and Compulsive Internet Use. It is further argued that a subgroup of compulsive Internet users should be classified as compulsive online gamers.

Indonesia is one of the largest e-commerce markets in Southeast Asia, as many as 5 million people do transactions in e-commerce, therefore more and more people use live chat service to communicate with customer service. In live chat, the customer service often asks customers’ data such as, full name, address, e-mail, transaction id, which aims to verify the purchase of the product. One of the risks that will happen is sniffing which will lead to the theft of confidential information that will cause huge losses to the customer. The anticipation that will be done is build an alternative security protocol for user interaction in live chat by using a cryptographic algorithm that is useful for protecting confidential messages. Live chat requires confidentiality and data integration with encryption and hash functions. The used algorithm are Rijndael 256 bits, RSA, and SHA256. To increase the complexity, the Rijndael algorithm will be modified in the S-box and ShiftRow sections based on the shannon principle rule, the results show that all pass the Randomness test, but the modification in Shiftrow indicates a better avalanche effect. Therefore the message will be difficult to be stolen or changed.

Internet language is the product of modern technology, especially for the advancement of Information Technology. It is a social and linguistic phenomenon which has its own stylistic and rhetoric patterns and styles compared with other languages. The reasons for the emergence of Internet language can be summarised into three kinds:firstly, the netizens need distinct languag⁃es to show their personalities and enhance the impacts of languages such as sadness, angriness and happiness; secondly, the key⁃board makes it hard to type the whole sentences when people online chatting or other activities;lastly, it is fast and convenient, especially when some online activities are time-consuming. Internet languages make the most use of the functions of linguistic deviation and satisfy the psychological and practical needs of netizens.

Adolescent Internet gambling is associated with concomitant addictive behaviors. This study aimed to assess the prevalence of Internet gambling practices, its impact upon psychosocial development and to evaluate the association between gambling practices and Internet addictive behavior among Cypriot adolescents. A cross-sectional study was conducted in a convenience sample (n = 805) of adolescents attending selected public schools (9th and 10th grades) in Cyprus. Anonymous self-completed questionnaires were used including the Internet Addiction Test and the Strengths and Difficulties Questionnaire. Among the study population (n = 805), approximately one third (n = 28; 34.9%) reported Internet gambling. Internet gamblers were twice as likely to utilize Internet café portals (adjusted odds ratio for gender and age, AOR: 2.13; 95% confidence interval, 95% CI: 1.56-2.91) for interactive game-playing (AOR: 6.84; 95% CI: 4.23-11.07), chat-rooms (AOR: 2.57; 95% CI: 1.31-4.85), and retrieval of sexual information (AOR: 1.99; 95% CI: 1.42-2.81). Among Internet gamblers 26.0% (n = 73) reported borderline addictive Internet use and 4.3% (n = 12) addictive behavior. Internet gamblers more often had comprehensive psychosocial and emotional maladjustment (AOR: 4.00; 95% CI: 1.97-8.13), including Abnormal Conduct Problems (AOR: 3.26; 95% CI: 2.00-5.32), Emotional Symptoms (AOR: 1.78; 95% CI: 1.02-3.11), and Peer Problems (AOR: 2.44; 95% CI: 1.08-5.48) scores. The multivariate regression analyses indicated that the single independent predictor associated with Internet addictive behavior was Internet gambling (AOR: 5.66; 95% CI: 1.45-22.15). Internet gambling is associated with addictive Internet use, as well as emotional maladjustment and behavioral problems, among Cypriot adolescents. Longitudinal studies are needed to elucidate whether Internet gambling constitutes a risk factor for the development of Internet addictive behavior among adolescents.

Stgeorge, Jennifer M; Fletcher, Richard J

2011-01-01

In the transition to fatherhood, men face numerous challenges. Opportunities to learn new practices and gain support are limited, although the provisions of father-specific spaces such as fathers' antenatal classes or "responsible fathering" programs are important advances. This article explores how men use the social space of a father-specific Internet chat room to learn about fathering. Messages to an Australian-hosted, father-specific chat room (for fathers of infants or young children) were examined, and three overlapping themes illustrated men's perceptions of their transition to fatherhood. The themes concerned recognition of and response to a lack of social space, services, and support for new fathers. The implications for fathers' perinatal education are discussed.

Social networks (1) have been embedded in our daily life for a long time. They constitute a powerful tool used nowadays for both searching and exchanging information on different issues by using Internet searching engines (Google, Bing, etc.) and Social Networks (Facebook, Twitter etc.). In this paper, are presented the results of a research based on the frequency and the type of the usage of the Internet and the Social Networks by the general public and the health professionals. The objectives of the research were focused on the investigation of the frequency of seeking and meticulously searching for health information in the social media by both individuals and health practitioners. The exchanging of information is a procedure that involves the issues of reliability and quality of information. In this research, by using advanced statistical techniques an effort is made to investigate the participant's profile in using social networks for searching and exchanging information on health issues. Based on the answers 93 % of the people, use the Internet to find information on health-subjects. Considering principal component analysis, the most important health subjects were nutrition (0.719 %), respiratory issues (0.79 %), cardiological issues (0.777%), psychological issues (0.667%) and total (73.8%). The research results, based on different statistical techniques revealed that the 61.2% of the males and 56.4% of the females intended to use the social networks for searching medical information. Based on the principal components analysis, the most important sources that the participants mentioned, were the use of the Internet and social networks for exchanging information on health issues. These sources proved to be of paramount importance to the participants of the study. The same holds for nursing, medical and administrative staff in hospitals.

Phrase Completion Test (TCF in a sample of 124 college students, directed to assess whether Internet chat is only a way to communicate or if through it, young people experiment -assuming fictitious roles and behaviors- involving aspects of their identities. The calculation of the TCF's Cronbach alpha showed a high internal consistency (0.91. The factorial analysis found an underlying structure formed by six factors (attitudes and consistent behavior between real life and virtual reality; possibilities and experiences offered by virtual reality; disguise and deceit; desinhibition, confusion and anguish feelings; evaluation of virtual experiences attitudes with regard to changes of identity of the other person, all of which together explain the 45.82% of the variance, value considered acceptable. An average of 17.46 over a total of 42 points, with a deviation standard of 9.01 and a minimum of 3 points and maximum of 38 points in the TCF, allow us to state that young people engage their identities when chatting on the Internet. The univariated variance's analysis for TCF total scored showed that gender variable was significative (p = 0.024. The multivariated variance's analysis for six factors of TCF found that males explored more possibilities of experiences offered by virtual reality (p = 0.025. Men disguised more frequently aspects of their identity and they deceived more than women did (p = 0.006 and valued in a more permissive way the experiences that commited one's self identity in chat (p = 0.023. With regard to the variable hours of internet chat, there was no evidence that could lead us to assert that this variable has an influence on experiences of experimenting with identity on Internet chat.

The Information and Communication Technologies (ICT) generate new styles of meeting people or connecting with friends or strangers. In this context, the internet and the mobile phone deserve special attention. This article deals with the maladaptive use of these technologies. By reviewing the literature published between 1991 and 2005 and indexed in the databases of PsycINFO, Medline, Psicodoc, IME, and ISOC, we aim to determine whether maladaptive use of these technologies can be considered a mental disorder, and if so, of which type. We describe the psychological phenomena of maladaptive use of the internet and mobile phones, we review research on prevalence and possible risk groups, and finally we discuss some of the criticisms made with regard to the existence and classification of this disorder. It is concluded that excessive use of the internet can lead to a mental disorder of the addictive type, which can particularly affect individuals with special emotional needs, as well as adolescents and young adults. Among specific applications of the internet, a major risk is found for the use of communicative and synchronic applications, such as chats and online role games, since they permit hyperpersonal communication, playing with different identities, and projections and dissociation without consequences in real life. Furthermore, the internet can play an important role in the development and maintenance of other addictions, such as pathological gambling and sex addiction. In contrast to the case of the internet, maladaptive use of mobile phones may be considered abuse, but not addiction, since their use does not lead to the rapid emotional changes or the playing with identities that can take place in chats and online role games.

Full Text Available This study examined ten EFL learners’ noticing of the corrective nature of a form of text-based SCMC (text chat feedback that combined a recast of a grammatical error with metalinguistic information. The feedback, termed a hybrid recast, was provided by a native-speaker interlocutor during two text chat activities: a spot-the-difference and picture-ordering task. Data was collected in two ways: analysis of task-based dyadic text chat interaction in which uptake was used as an indicator of learner noticing, and a post-task questionnaire containing questions that identified evidence of learner noticing. Interaction analysis showed that learners responded to almost two thirds of the hybrid recasts with uptake. In addition, every learner provided evidence that they had correctly perceived at least some of the hybrid recasts as corrective in their post-task questionnaire responses.

An increasing number of medical school libraries offer chat service to provide immediate, high quality information at the time and point of need to students, faculty, staff, and health care professionals. Part 2 of Chat Reference Service in Medical Libraries presents a snapshot of the current trends in chat reference service in medical school libraries. In late 2002, 25 (21%) medical school libraries provided chat reference. Trends in chat reference services in medical school libraries were compiled from an exploration of medical school library Web sites and informal correspondence from medical school library personnel. Many medical libraries are actively investigating and planning new chat reference services, while others have decided not to pursue chat reference at this time. Anecdotal comments from medical school library staff provide insights into chat reference service.

Optimizing Fracture Treatments in a Mississippian "Chat" Reservoir, South-Central Kansas

Energy Technology Data Exchange (ETDEWEB)

K. David Newell; Saibal Bhattacharya; Alan Byrnes; W. Lynn Watney; Willard Guy

2005-10-01

This project is a collaboration of Woolsey Petroleum Corporation (a small independent operator) and the Kansas Geological Survey. The project will investigate geologic and engineering factors critical for designing hydraulic fracture treatments in Mississippian ''chat'' reservoirs. Mississippian reservoirs, including the chat, account for 159 million m3 (1 billion barrels) of the cumulative oil produced in Kansas. Mississippian reservoirs presently represent {approx}40% of the state's 5.6*106m3 (35 million barrels) annual production. Although geographically widespread, the ''chat'' is a heterogeneous reservoir composed of chert, cherty dolomite, and argillaceous limestone. Fractured chert with micro-moldic porosity is the best reservoir in this 18- to 30-m-thick (60- to 100-ft) unit. The chat will be cored in an infill well in the Medicine Lodge North field (417,638 m3 [2,626,858 bbls] oil; 217,811,000 m3 [7,692,010 mcf] gas cumulative production; discovered 1954). The core and modern wireline logs will provide geological and petrophysical data for designing a fracture treatment. Optimum hydraulic fracturing design is poorly defined in the chat, with poor correlation of treatment size to production increase. To establish new geologic and petrophysical guidelines for these treatments, data from core petrophysics, wireline logs, and oil-field maps will be input to a fracture-treatment simulation program. Parameters will be established for optimal size of the treatment and geologic characteristics of the predicted fracturing. The fracturing will be performed and subsequent wellsite tests will ascertain the results for comparison to predictions. A reservoir simulation program will then predict the rate and volumetric increase in production. Comparison of the predicted increase in production with that of reality, and the hypothetical fracturing behavior of the reservoir with that of its actual behavior, will serve as tests of

In 2013, the American College of Chest Physicians (CHEST) launched a Twitter chat series using the hashtag #pulmcc to educate and advocate for topics related to pulmonary, critical care, and sleep medicine. To assess the reach of these chats, we analyzed the metrics using Symplur analytics, and compared data from each chat, as well as participant data. Since December 19, 2013, there have been 12 Twitter chats: six have been on critical care-related topics, four have been on pulmonary-/sleep-related topics, and two have been conducted during the CHEST annual meeting on more general topics. During these 1-h Twitter chats, there were a total of 4,212 tweets by 418 participants, resulting in 9,361,519 impressions (ie, views). There were similar numbers of participants and tweets in the three categories of Twitter chats, but there was a significantly greater reach during the more general Twitter chats conducted at the CHEST annual meeting, with 1,596,013 ± 126,472 impressions per chat session at these chats, compared with 739,203 ± 73,109 impressions per chat session during the critical care Twitter chats and 621,965 ± 123,933 impressions per chat session in the pulmonary/sleep chats. Seventy-five participants participated in two or more #pulmcc Twitter chats, and the average percent of return participants in each chat was 30% ± 7%. Most of the return participants were health-care providers. Twitter chats can be a powerful tool for the widespread engagement of a medical audience.

Ireland, David; Liddle, Jacki; McBride, Simon; Ding, Hang; Knuepffer, Christina

2015-01-01

People with Parkinson's disease are known to have difficulties in language and communication. This paper proposes the use of an artificial conversational agent, commonly known as a chat-bot that runs on a smart-phone device and performs two-way conversation with the user. In this paper, initial work on a Parkinson's disease themed chat-bot that interacts with the user relative to their symptoms is presented. Potential dialogues are provided to illustrate the various roles chat-bots can play in the management of Parkinson's disease. The chat-bot can be used for measuring voice and communication outcomes during the daily life of the user, and for gaining information about challenges encountered. Moreover, it is anticipated that it may also have an educational and support role. The chat-bot is now ready for usability testing with a clinical population.

2001-06-01

Full Text Available The internet as dynamic language environment: manifestations of language change in Internet Afrikaans It is generally accepted that the growing interest in the Internet has opened up new horizons for language research. Chenault (1997:1 asserts that the Internet is not about technology or information, but about communication. The aim with this article is to explore the Internet as a dynamic language environment in which emerging patterns of language change in modernday Afrikaans could be traced. Firstly, attention is paid to ways in which the internet speech community could be defined as a coherent speech community. A second aim with this article is to scrutinise the dichotomy between spoken and written language. This is done in order to indicate that linguistic innovations, which usually emerge from social interaction, find their way into written language in digital communication. The third aim is to take a close look at various forms or patterns of language change in Afrikaans as they are presently used in Afrikaans chat rooms on the Internet. The article concludes that Internet Afrikaans could be regarded as an aspect of virtual reality for Afrikaans because systematic patterns of language change which started long ago in Afrikaans are confirmed by the Internet language environment.

The Internet has emerged as an important tool for the delivery of health promotion and disease prevention interventions. Our community-based participatory research (CBPR) partnership developed and piloted CyBER/testing, a culturally congruent intervention designed to promote HIV testing among men who have sex with men (MSM) within existing Internet chat rooms. Using a quasi-experimental, single-group study design, cross-sectional data were collected from chat room participants, known as "chatters," at pretest (n = 346) and posttest (n = 315). Extant profile data also were collected to describe the demographics of the online population. The intervention significantly increased self-reported HIV testing among chatters overall, increasing rates from 44.5% at pretest to nearly 60% at posttest (p testing at posttest. Findings suggest that chat room-based HIV testing intervention may increase testing among MSM who may be difficult to reach in traditional physical spaces.

Gill Needham

2006-03-01

Full Text Available Objective – To investigate reasons why undergraduate and postgraduate students choose to use chat reference services and their satisfaction with the experience. Design – User survey. Setting – Large academic library in the United States. Subjects – A total of 341 library users took part in the survey. Of these, 79 were graduate students, 215 undergraduates, 21 staff, 5 alumni and 21 members of the public. Method – A user survey form was posted on the library website for a period of one month (March 2003. Users of the chat reference service received an automatic closing message asking them to complete the survey. Responses were fed into a database to be analysed by the research staff. Additional data was also gathered about the behaviour of all users of the chat service during that period – both responders and non‐responders. Main results – The most popular reason for choosing to use a chat service was the desire for a speedy response, followed by ‘distance from the library’. Responders chose to use chat to ask a range of different kinds of questions. Nearly half (45% were looking for a specific resource and 23% were seeking help at the beginning of their research. There were notable differences between undergraduate and graduate students. Twice as many undergraduates as graduates used the service to help them get started on their research. Graduates were three times as likely as undergraduates to be using the service to address technical problems they were having with the website. Overall satisfaction with the service was extremely high, with 77.5% rating it 5 out of 5 and 94.5% giving it 4 or 5 out of 5. Conclusion – Chat reference services are popular with users primarily because they are quick and convenient. However, users expect that these services will be able to deal with all types of questions, including help with research. This challenges an assumption by library staff that the medium is only suitable for short

Haven't we met somewhere before? The effects of a brief Internet introduction on social anxiety in a subsequent face to face interaction.

Markovitzky, Omer; Anholt, Gideon E; Lipsitz, Joshua D

2012-05-01

Social anxiety occurs in a range of social situations, the salience of which is influenced by prevailing modes of social contact. The emergence of computer mediated communication (CMC), buoyed by the recent explosion of social networks, has changed the way many people make and maintain social contacts. We randomly assigned 30 socially anxious and 30 low social anxiety participants to a brief internet chat introduction or a control internet surfing condition followed by a standardized face to face (FTF) interaction. We hypothesized that for socially anxious participants the chat introduction would reduce anxiety of and preference to avoid the subsequent FTF interaction. Results supported hypotheses for most indices. Findings suggest that, at least for the common situation in which internet chat precedes FTF interaction with the same person, such contact may reduce social anxiety. It is not known whether this decrease would generalize to FTF contact in other contexts. It is suggested that CMC might be construed as a particularly useful form of safety behavior that may help in the allocation of attentional resources to process new information relevant for disconfirmation of negative beliefs maintaining social anxiety. Potential clinical implications are discussed. Copyright © 2012 Elsevier Ltd. All rights reserved.

This study assessed Internet use and attitudes toward illicit use of the Internet in a sample of Russian college students. A sample comprised of 198 students was recruited from a university in Moscow. Each participant completed a survey assessing demographic characteristics, Internet use, and attitudes towards engaging in illicit behaviors over the Internet. About half of the students reported that they used the Internet at least several times a year, with 8% reporting daily use of the Internet. Among Internet users, most reported having Internet access either at home or at a friends' home, and 16 % reported having Internet access from work, school, or a computer center. Among Internet users, the main purpose was for school-related activities (60%), followed by e-mail (55%), entertainment (50%), chatting (24%), and searching for pornography (6%). Although most students thought it was inappropriate to read someone else's e-mail, use someone else's password or credit card information without their permission, or break into someone's computer, many students did endorse those illicit behaviors. Over a fifth of the students reported that they knew hackers. Forty three percent of students agreed that people make too much fuss about watching videos, movies or downloading music on the Internet without paying. Males were more likely than females to report using the Internet for entertainment purposes (p = 0.006) and were more likely to agree that it was okay to break into someone's computer (p = 0.04). The results of this study suggest that these Russian college students predominately use the Internet to help with their schoolwork, to communicate with others, and for entertainment. These results also suggest that interventions may be useful to change attitudes endorsing illicit uses of the Internet.

The Role of Parents in Problematic Internet Use among US Adolescents

Directory of Open Access Journals (Sweden)

Amy Bleakley

2016-06-01

Full Text Available The internet has transformed the way youth communicate, learn, and network, with implications for their broader social, psychological, and physical health and well-being. With the technological capability of accessing the internet from anywhere, at any time, paired with the enormous variety of internet activities in which youth engage—from social networking to chatting to streaming videos to playing games to watching television content—instances of problematic internet behavior have emerged. We conducted an online national survey of 629 US adolescents ages 12–17 years old and a matching survey of one of their parents. We investigated the relationship between problematic internet behavior and parental monitoring, parental mediation of internet use, and parental estimates of their adolescent’s time spent using computers. Analyses showed that problematic internet use was associated with less parental monitoring and parental mediation and poorer parental relationships. Adolescents that spent a lot of time on the computer were also more likely to engage in problematic internet use. Although we cannot determine the direction of the relationships, results support the important role of parents in adolescents’ problematic internet use.

Difficulties in everyday life: young persons with attention-deficit/hyperactivity disorder and autism spectrum disorders perspectives. A chat-log analysis.

Science.gov (United States)

Ahlström, Britt H; Wentz, Elisabet

2014-01-01

This study focuses on the everyday life of young persons with attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD). There are follow-up studies describing ADHD, and ASD in adults, and residual impairments that affect life. Few qualitative studies have been conducted on the subject of their experiences of everyday life, and even fewer are from young persons' perspectives. This study's aim was to describe how young persons with ADHD and ASD function and how they manage their everyday life based on analyses of Internet-based chat logs. Twelve young persons (7 males and 5 females aged 15-26) diagnosed with ADHD and ASD were included consecutively and offered 8 weeks of Internet-based Support and Coaching (IBSC). Data were collected from 12 chat logs (445 pages of text) produced interactively by the participants and the coaches. Qualitative content analysis was applied. The text was coded and sorted into subthemes and further interpreted into themes. The findings revealed two themes: "fighting against an everyday life lived in vulnerability" with the following subthemes: "difficult things," "stress and rest," and "when feelings and thoughts are a concern"; and the theme "struggling to find a life of one's own" with the following subthemes: "decide and carry out," "making life choices," and "taking care of oneself." Dealing with the problematic situations that everyday encompasses requires personal strength and a desire to find adequate solutions, as well as to discover a role in society. This study, into the provision of support and coaching over the Internet, led to more in-depth knowledge about these young persons' everyday lives and revealed their ability to use IBSC to express the complexity of everyday life for young persons with ADHD and ASD. The implications of the findings are that using online coaching makes available new opportunities for healthcare professionals to acknowledge these young persons' problems.

Iterative Chat Transcript Analysis: Making Meaning from Existing Data

Directory of Open Access Journals (Sweden)

Steven Baumgart

2016-04-01

Full Text Available Objective – In order to better contextualize library data about patron satisfaction with reference services, we analyzed an existing corpus of chat transcripts. Having conducted a similar analysis in 2010, we also compared librarian behaviors over time. Methods – Drawing from the library literature, we identified a set of librarian behaviors closely associated with patron satisfaction. These behaviors include listening to and understanding patrons’ needs, inviting patrons to use the service again, and providing instruction or completing a search for patrons. Analysis of the chat transcripts included establishing a coding schema, applying these codes to individual chat transcripts, and analyzing these codes across the corpus of transcripts for frequency and correlation with other codes. The currently presented analysis used chat transcripts from the fall of 2013 and seeks changes in librarian behavior over time in order to gauge the success of establishing best practices and improving training standardization over the last three years. Results – The analysis shows that librarian behaviors have changed over time, pointing to what campus librarians are doing well, and that implementation of best practices at a campus level after the 2010 analysis may have increased these positive behaviors. The analysis also shows opportunities for further standardization and reinforcement of best practices. Conclusion – Qualitative analysis of already-collected data serves as a model for other units and suggests areas for process improvement, including enhanced coder training and code schema design. Further analysis of chat patrons’ questions is also warranted, including investigation of the relationship between subject- and location-specific questions and referrals.

Full Text Available Accurate network traffic classification at early stage is very important for 5G network applications. During the last few years, researchers endeavored hard to propose effective machine learning model for classification of Internet traffic applications at early stage with few packets. Nevertheless, this essential problem still needs to be studied profoundly to find out effective packet number as well as effective machine learning (ML model. In this paper, we tried to solve the above-mentioned problem. For this purpose, five Internet traffic datasets are utilized. Initially, we extract packet size of 20 packets and then mutual information analysis is carried out to find out the mutual information of each packet on n flow type. Thereafter, we execute 10 well-known machine learning algorithms using crossover classification method. Two statistical analysis tests, Friedman and Wilcoxon pairwise tests, are applied for the experimental results. Moreover, we also apply the statistical tests for classifiers to find out effective ML classifier. Our experimental results show that 13–19 packets are the effective packet numbers for 5G IM WeChat application at early stage network traffic classification. We also find out effective ML classifier, where Random Forest ML classifier is effective classifier at early stage Internet traffic classification.

Science.gov (United States)

Zheng, Deli; Tian, Feng; Liu, Jun; Zheng, Qinghua; Qin, Jiwei

In order to compensate for lack of emotion communication between teachers and students in e-learning systems, we have designed and implemented the EmotionChat -- a web chatroom with emotion regulation. EmotionChat perceives e-learners' emotional states based on interactive text. And it recommends resources such as music, cartoons, and mottos to an e-learner when it detects negative emotional states. Meanwhile, it recommends emotion regulation cases to the e-learner's listeners and teachers. The result of our initial experiment shows that EmotionChat can recommend valuable emotion regulation policies for e-learners.

The article’s overall focus is on “turn-taking organisation as the fundamental and generic aspect of interaction organisation” (Drew & Heritage, 1992, p. 25, including the use of turn-taking rules, adjacency pairs, and the importance of pauses. Even though the employee and the union members do not know one another and cannot see, hear, or touch one another, it is possible to detect an informal, pleasant tone in their interactions. This challenges the basically asymmetrical relationship between employee and customer, and one can sense a further level of asymmetry. In terms of medium, chat interactions exist via various references to other media, including telephone calls and e-mails.

Accelerated development of the Internet technologies, including those relevant to the atomic and molecular physics, poses new requirements for the proper communication between computers, users and applications. To this end, a new standard for atomic and molecular data exchange that would reflect the recent achievements in this field becomes a necessity. We report here on development of the Atomic and Molecular Data Markup Language (AMDML) that is based on eXtensible Markup Language (XML). The present version of the AMDML Schema covers atomic spectroscopic data as well as the electron-impact collisions. (author)

The Internet is becoming a new erotic oasis for obtaining sex online or in person. We reviewed the literature on cybersex and compared differences in data from samples of homosexually active men obtained on identical questionnaires from a conventional written questionnaire, distributed through the mailing and contact lists of a large national gay organization in Sweden, and through the same organization's website and chat room. A total of 716 written questionnaires and 678 Internet questionnaires were obtained. The Internet sample was younger, more likely to live in small towns or cities, live with parents or a girlfriend, and have lower formal education. They are less likely to have previous sexual experience solely with other men (one in three of the Internet sample vs. 1 in 14 of the written sample defined themselves as bisexual) and more likely to visit erotic oases such as bathhouses, video clubs and erotic movie houses. They also visited Internet chat rooms more frequently (86% of the Internet sample vs. 50% of the written sample). One third of the Internet sample wanted the opportunity to talk with an expert about HIV compared with a quarter of the written sample. Sexual practices between the two samples were generally similar, although the Internet sample reported significantly less body contact, kissing, hugging, mutual masturbation, and more condom use for anal intercourse with steady partners. Over four times as many of the Internet samples reported sex with women in the past year as the written sample. These data indicate that Internet data collection is feasible and that this mode of data collection, despite the nonrandom and self-selected nature of both types of samples, is likely to be more significantly oriented toward the young, geographically more isolated, and more behaviorally and self-identified bisexual respondent than conventionally distributed written questionnaires.

A PROPOSED MAPPING ARCHITECTURE BETWEEN IAX AND JINGLE PROTOCOLS

Full Text Available Nowadays, multimedia communication has improved rapidly to allow people to communicate via the Internet. However, Internet users cannot communicate with each other unless they use the same chatting applications since each chatting application uses a certain signaling protocol to make the media call. The mapping architecture is a very critical issue since it solves the communication problems between any two protocols, as well as it enables people around the world to make a voice/video call even if they use different chatting applications. Providing the interoperability between different signaling protocols and multimedia applications takes the advantages of more than one protocol. Many mapping architectures have been proposed to ease exchanging the media between at least two users without facing any difficulties such as SIP-Jingle, IAX-RSW, H.323-MGCP, etc. However, the design of any of the existing mapping architectures has some weaknesses related to larger delay, time consuming, and security matters. The only way to overcome these problems is to propose an efficient mapping architecture. This paper proposed a new mapping architecture between Inter-Asterisk eXchange Protocol and Jingle Protocol. The proposed mapping architecture consists of IAX domain (IAX client, IAX server, IAX-to-Jingle gateway, and Jingle domain (Jingle client, Jingle server, Jingle-to-IAX gateway. The tasks of the translation gateways are represented by the URI conversion, media capability exchange, translator of call setup and teardown signals, and real time media transmission.

Full Text Available This study focused on the level of penetration of Internet usage among undergraduate students in Nigeria using Obafemi Awolowo University as a case study. Result showed that about 92% of undergraduate students have embraced the Internet and are using it consistently. The online mean time is 3.5hrs/week while on the average, undergraduate experience of Internet usage is about 4years. We found also that the students use the Internet mostly for e-mail, information search and online chatting; all of these were found to have significant impact on their academics and social life. Further analysis revealed that gender attitude is also an important issue; male students appear to use the Internet more than their female counterparts; just as science based students use it more than the non-science based students. The paper therefore recommends appropriate policies for all higher schools of learning in Nigeria to facilitate further diffusion and use of the Internet.

The aim of the study was to explore the characteristics of Internet use among elementary school eighth-graders in the Bjelo- var-Bilogora County, to evaluate gender and sociodemographic differences, and to examine predictors for Internet addiction. The study included 437 (female 51%) eighth-graders, mean age 13.8 ± 0.5 years. An anonymous questionnaire was used to measure the participants' Internet use, the functions for which they used Internet, their parents' attitude towards the child's Internet use, and their signs of Internet addiction. Logistic regression was conducted to evaluate predictors for Internet addiction. The majority of children (71.5%) reported using Internet every day. Considering important risk factors of Internet addiction development, we found that 32% of children almost always stayed on-line longer than intended, 13% of boys and 4% of girls almost always neglected chores to spend more time on-line and 51.7% of children thought their life would be boring and uninteresting without the Internet. There was no significant difference between urban and rural students. In terms of the function for which they used the Internet, they were mostly engaged in on-line community/chat websites (70%), to listen to music and watch movies (81 %), and boys in gaming websites. Most of the students (43.4%) spent 1-2 hours daily on-line, 26.2% of students spent 3-4 hours on-line, and 9% spent more than 5 hours daily on-line. In conclusion, more public health preventive measures should be conducted to raise public awareness and concern about the negative effect of Internet use and Internet addiction, especially in the young population.

The relationship between elderly suicide rates and the internet: a cross-national study.

Shah, Ajit

2010-05-01

Suicide rates generally increase with age. Internet websites and chat rooms have been reported both to promote suicides and to have a positive beneficial effect on suicidal individuals. The role of the internet in elderly suicides has not been studied. The relationship between elderly suicide rates and the prevalence of internet users was examined in a cross-national study using data from the World Health Organization and the United Nations website. The prevalence of internet users was significantly and positively correlated with suicide rates in both genders in the age bands 65-74 years and 75+ years. On multiple regression analysis the prevalence of internet users was independently associated with suicide rates in both genders in both age bands. Caution should be exercised in the attribution of a causal relationship and the direction of this relationship because of the cross-sectional and ecological study design whereby the findings are subject to ecological fallacy. However, the findings identify and support a need for further research.

Up to 9% of young people suffer from depression. Unfortunately, many in need of help remain untreated. The Internet offers anonymous ways to help depressed youth, especially those who are reluctant to search for help because of fear of stigma. Our goal was to evaluate the effectiveness of an individual chat treatment based on Solution-Focused Brief Therapy (SFBT) to young individuals aged 12-22 years with depressive symptoms by comparing it to a waiting list control group. For this study, 263 young people with depressive symptoms were randomized to the Web-based SFBT intervention, PratenOnline, or to a waiting list control condition. The chat treatment was delivered by trained professionals. Groups were compared on depressive complaints as measured by the Center for Epidemiologic Studies Depression Scale (CES-D) after 9 weeks and 4.5 months. For the chat group only, changes in depressive symptoms at 7.5 months after baseline were explored. The experimental SFBT condition (n=131) showed significantly greater improvement than the waiting list condition (n=132) in depressive symptoms at 9 weeks and 4.5 months on the CES-D, with a small between group effect size at 9 weeks (d=0.18, 95% CI -0.10 to 0.47) and a large effect size at 4.5 months (d=0.79, 95% CI 0.45-1.08). The percentage of participants showing a reliable and clinically significant change in depression was significantly larger for the SFBT intervention at 4.5 months only (28.2% vs 11.4% for the waiting list, PWeb-based SFBT chat intervention of PratenOnline was more effective than a waiting list control group in reducing depressive symptoms, and effects were larger at follow-up then at post-treatment. More studies are needed to find out if outcomes will be replicated, especially for those younger than 18 year old.

Over the past decades, Internet use has grown substantially, and it now serves people as a supportive tool that is used regularly and-in large parts of the world-inevitably. Some people develop problematic Internet use, which may lead to addictive behavior and it is becoming important to explore the risk factors for compulsive Internet use. Data were analyzed on compulsive Internet use [with the Compulsive Internet Use Scale (CIUS)] from 5247 monozygotic (MZ) and dizygotic (DZ) adolescent twins registered with the Netherlands Twin Register. The participants form a sample that is informative for genetic analyses, allowing the investigation of the causes of individual differences in compulsive Internet use. The internal consistency of the instrument was high and the 1.6-year test-retest correlation in a subsample (n = 902) was 0.55. CIUS scores increased slightly with age. Remarkably, gender did not explain variation in CIUS scores, as mean scores on the CIUS were the same in boys and girls. However, the time spent on specific Internet activities differed: boys spent more time on gaming, whereas girls spent more time on social network sites and chatting. The heritability estimates were the same for boys and girls: 48 percent of the individual differences in CIUS score were influenced by genetic factors. The remaining variance (52 percent) was due to environmental influences that were not shared between family members. Because a life without Internet is almost impossible nowadays, it is important to further explore the determinants of compulsive Internet use, including genetic risk factors. © 2015 The Authors.

Full Text Available Digital evidence plays a crucial role in child pornography investigations. However, in the following case study, the authors argue that the behavioral analysis or “profiling” of digital evidence can also play a vital role in child pornography investigations. The following case study assessed the Internet Browsing History (Internet Explorer Bookmarks, Mozilla Bookmarks, and Mozilla History from a suspected child pornography user’s computer. The suspect in this case claimed to be conducting an ad hoc law enforcement investigation. After the URLs were classified (Neutral; Adult Porn; Child Porn; Adult Dating sites; Pictures from Social Networking Profiles; Chat Sessions; Bestiality; Data Cleaning; Gay Porn, the Internet history files were statistically analyzed to determine prevalence and trends in Internet browsing. First, a frequency analysis was used to determine a baseline of online behavior. Results showed 54% (n = 3205 of the URLs were classified as “neutral” and 38.8% (n = 2265 of the URLs were classified as a porn website. Only 10.8% of the URLs were classified as child pornography websites. However when the IE history file was analyzed by visit, or “hit,” count, the Pictures/Profiles (31.5% category had the highest visit count followed by Neutral (19.3%, Gay Porn (17%, and Child Porn (16.6%. When comparing the frequency of URLs to the Hit Count for each pornography type, it was noted that the accused was accessing gay porn, child porn, chat rooms, and picture profiles (i.e., from Facebook more often than adult porn and neutral websites. The authors concluded that the suspect in this case was in fact a child pornography user and not an ad hoc investigator, and the findings from the behavioral analysis were admitted as evidence in the sentencing hearing for this case. The authors believe this case study illustrates the ability to conduct a behavioral analysis of digital evidence. More work is required to further validate the

Online Chat Dependency: The Influence of Social Anxiety

Wang, Chih-Chien; Chang, Shu-Chen

Recent developments in information technology have made it easy for people to “chat” online with others in real time, and many do so regularly. “Virtual” relationships can be attractive, especially for people with social interaction problems in the “real world”. This study examines the influence on online chat dependency of three dimensions of social anxiety: general social situation fear, negative evaluation fear, and novel social situation fear. Participants of this study were 454 college students. The survey results show that negative evaluation fear and general social situation fear are relative to online chat dependency, while novel social situation fear does not seem to be a relevant factor.

Full Text Available This study focuses on the everyday life of young persons with attention-deficit/hyperactivity disorder (ADHD and autism spectrum disorder (ASD. There are follow-up studies describing ADHD, and ASD in adults, and residual impairments that affect life. Few qualitative studies have been conducted on the subject of their experiences of everyday life, and even fewer are from young persons’ perspectives. This study's aim was to describe how young persons with ADHD and ASD function and how they manage their everyday life based on analyses of Internet-based chat logs. Twelve young persons (7 males and 5 females aged 15–26 diagnosed with ADHD and ASD were included consecutively and offered 8 weeks of Internet-based Support and Coaching (IBSC. Data were collected from 12 chat logs (445 pages of text produced interactively by the participants and the coaches. Qualitative content analysis was applied. The text was coded and sorted into subthemes and further interpreted into themes. The findings revealed two themes: “fighting against an everyday life lived in vulnerability” with the following subthemes: “difficult things,” “stress and rest,” and “when feelings and thoughts are a concern”; and the theme “struggling to find a life of one's own” with the following subthemes: “decide and carry out,” “making life choices,” and “taking care of oneself.” Dealing with the problematic situations that everyday encompasses requires personal strength and a desire to find adequate solutions, as well as to discover a role in society. This study, into the provision of support and coaching over the Internet, led to more in-depth knowledge about these young persons’ everyday lives and revealed their ability to use IBSC to express the complexity of everyday life for young persons with ADHD and ASD. The implications of the findings are that using online coaching makes available new opportunities for healthcare professionals to acknowledge

2014-05-01

This study sought to evaluate a book chat intervention based on Lisa Genova's novel, Still Alice, to influence long-term care (LTC) staff perceptions and attitudes when caring for individuals with dementia. A qualitative descriptive design was used. Eleven participants partook in a 2.5-hour book chat at a southern Ontario LTC facility. Following the book chat, participants answered two open-ended questions to assess how the book chat influenced their views on dementia. Thematic content analysis was used to analyze the qualitative questionnaire. Content analysis of the participants' responses revealed that the book chat positively influenced their attitudes and perceptions toward dementia, particularly by providing more insight into the individual's personal struggle with the disease. Furthermore, participants found that the book chat influenced their care practices. By creating innovative learning opportunities, attitudes and perceptions about dementia care can be transcended and greatly benefit staff, family, and residents. Copyright 2014, SLACK Incorporated.

Pontes, Halley M; Szabo, Attila; Griffiths, Mark D

2015-06-01

Recent research has examined the context in which preference for specific online activities arises, leading researchers to suggest that excessive Internet users are engaged in specific activities rather than 'generalized' Internet use. The present study aimed to partially replicate and expand these findings by addressing four research questions regarding (i) participants' preferred online activities, (i) possible expected changes in online behavior in light of hypothetical scenarios, (iii) perceived quality of life when access to Internet was not possible, and (iv) how participants with self-diagnosed Internet addiction relate to intensity and frequency of Internet use. A cross-sectional design was adopted using convenience and snowball sampling to recruit participants. A total of 1057 Internet users with ages ranging from 16 to 70 years (M age  = 30 years, SD = 10.84) were recruited online via several English-speaking online forums. Most participants indicated that their preferred activities were (i) accessing general information and news, (ii) social networking, and (iii) using e-mail and/or online chatting. Participants also reported that there would be a significant decrease of their Internet use if access to their preferred activities was restricted. The study also found that 51% of the total sample perceived themselves as being addicted to the Internet, while 14.1% reported that without the Internet their life would be improved. The context in which the Internet is used appears to determine the intensity and the lengths that individuals will go to use this tool. The implications of these findings are further discussed.

Validation of a new scale for measuring problematic internet use: implications for pre-employment screening.

Science.gov (United States)

Davis, Richard A; Flett, Gordon L; Besser, Avi

2002-08-01

The current study introduced a theory-driven, multidimensional measure of problematic Internet use: the Online Cognition Scale (OCS). Undergraduate students (n = 211) in an industrial/organizational psychology course completed the OCS, along with measures of procrastination, rejection sensitivity, loneliness, depression, and impulsivity. A confirmatory factor analysis indicated that problematic Internet use consists of four dimensions: diminished impulse control, loneliness/depression, social comfort, and distraction. As hypothesized, the OCS predicted all of the study variables in the expected directions. Representing a departure from previous research in this area, the current article focused on procrastination, impulsivity, and social rejection as key elements of problematic Internet use. Furthermore, interactive applications (e.g., chat) were most related to problematic Internet use, and scores on the OCS predicted being reprimanded at school or work for inappropriate Internet use. As a result, the utility of the OCS for both clinical assessment of Internet addiction and as an organizational preemployment screening measure to identify potential employees who are likely to abuse the Internet in the workplace (also known as "cyberslacking") were discussed.

To evaluate (a) the association between Internet addiction and aggressive behaviors, as well as the moderating effects of gender, school, and depression on this association; and (b) to evaluate the association between Internet activities and aggressive behaviors. A total of 9405 adolescents were recruited into this study and completed the questionnaires. Their aggressive behaviors, with or without Internet addiction, Internet activities, demographic data, with or without depression, self-esteem, family function, and the watching of violent TV were assessed. The results demonstrated that after controlling for the effects of shared associated factors and watching violent TV programs, adolescents with Internet addiction were more likely to have aggressive behaviors during the previous year. The association was more significant among adolescents in junior high schools than in senior high/vocational schools. Online chatting, adult sex Web viewing, online gaming, online gambling, and Bulletin Board System were all associated with aggressive behaviors. The results suggest that preventive programs for aggressive behaviors should pay attention to Internet addiction among adolescents. Also, intervention to prevent the effects of Internet addiction on aggressive behaviors should be conducted as early as possible.

The authors proposed a model for dental education based on WeChat public platform. In this model, teachers send various kinds of digital teaching information such as PPT，word and video to the WeChat public platform and students share the information for preview before class and differentiate the key-point knowledge from those information for in-depth learning in class. Teachers also send reference materials for expansive learning after class. Questionaire through the WeChat public platform is used to evaluate teaching effect of teachers and improvement may be taken based on the feedback questionnaire. A discussion and interaction based on WeCchat between students and teacher can be aroused on a specific topic to reach a proper solution. With technique development of mobile terminal, mobile class will come true in near future.

2012-12-01

This study explores whether Internet users have different privacy concerns regarding the information contained in electronic medical records (EMRs) according to gender, age, occupation, education, and EMR awareness. Based on the Concern for Information Privacy (CFIP) scale developed by Smith and colleagues in 1996, we conducted an online survey using 15 items in four dimensions, namely, collection, unauthorized access, secondary use, and errors, to investigate Internet users' concerns regarding the privacy of EMRs under health information exchanges (HIE). We retrieved 213 valid questionnaires. The results indicate that the respondents had substantial privacy concerns regarding EMRs and their educational level and EMR awareness significantly influenced their privacy concerns regarding unauthorized access and secondary use of EMRs. This study recommends that the Taiwanese government organizes a comprehensive EMR awareness campaign, emphasizing unauthorized access and secondary use of EMRs. Additionally, to cultivate the public's understanding of EMRs, the government should employ various media, especially Internet channels, to promote EMR awareness, thereby enabling the public to accept the concept and use of EMRs. People who are highly educated and have superior EMR awareness should be given a comprehensive explanation of how hospitals protect patients' EMRs from unauthorized access and secondary use to address their concerns. Thus, the public can comprehend, trust, and accept the use of EMRs, reducing their privacy concerns, which should facilitate the future implementation of HIE.

In this article, we will discuss what is known about a surprisingly popular phenomenon in the Middle East-the use of social media to communicate. We will begin with a discussion of what "social media" sites are (sites such as Facebook, Your Middle East, YouTube, Flickr, Muslima.com, chat rooms, and instant messaging) and point out how common they are in the Middle East. Next, we will discuss the reasons why men and women are currently using Internet and social media. Finally, we will discuss what impact social media have had on politics, political dissent, education, and men's and women's relationships-and the impact they might be expected to have in future years. Finally, we will focus on the impact of such media on men's and women's relationships-including cross-gender friendships, romantic relationships, and sexual relationships.

Peterson, Courtney M; Apolzan, John W; Wright, Courtney; Martin, Corby K

2016-11-01

We conducted two studies to test the validity, reliability, feasibility and acceptability of using video chat technology to quantify dietary and pill-taking (i.e. supplement and medication) adherence. In study 1, we investigated whether video chat technology can accurately quantify adherence to dietary and pill-taking interventions. Mock study participants ate food items and swallowed pills, while performing randomised scripted 'cheating' behaviours to mimic non-adherence. Monitoring was conducted in a cross-over design, with two monitors watching in-person and two watching remotely by Skype on a smartphone. For study 2, a twenty-two-item online survey was sent to a listserv with more than 20 000 unique email addresses of past and present study participants to assess the feasibility and acceptability of the technology. For the dietary adherence tests, monitors detected 86 % of non-adherent events (sensitivity) in-person v. 78 % of events via video chat monitoring (P=0·12), with comparable inter-rater agreement (0·88 v. 0·85; P=0·62). However, for pill-taking, non-adherence trended towards being more easily detected in-person than by video chat (77 v. 60 %; P=0·08), with non-significantly higher inter-rater agreement (0·85 v. 0·69; P=0·21). Survey results from study 2 (n 1076 respondents; ≥5 % response rate) indicated that 86·4 % of study participants had video chatting hardware, 73·3 % were comfortable using the technology and 79·8 % were willing to use it for clinical research. Given the capability of video chat technology to reduce participant burden and outperform other adherence monitoring methods such as dietary self-report and pill counts, video chatting is a novel and promising platform to quantify dietary and pill-taking adherence.

Recognizing the importance of digital communication, major suicide prevention helplines have started offering crisis intervention by chat. To date there is little evidence supporting the effectiveness of crisis chat services. To evaluate the reach and outcomes of the 113Online volunteer-operated crisis chat service, 526 crisis chat logs were studied, replicating the use of measures that were developed to study telephone crisis calls. Reaching a relatively young population of predominantly females with severe suicidality and (mental) health problems, chat outcomes for this group were found to be comparable to those found for crisis calls to U.S. Lifeline Centers in 2003-2004, with similar but not identical associations with specific helpers' styles and attitudes. Our findings support a positive effect of the 113Online chat service, to be enhanced by practice standards addressing an apparent lack of focus on the central issue of suicidality during chats, as well as by the development of best practices specific for online crisis intervention. © 2016 The American Association of Suicidology.

Recently, WeChat has been widely used in China. The positive and negative effects of WeChat on users have received attention from researchers gradually. Using the questionnaire method, we recruited 339 undergraduates and graduates as participants, and tested the effects of WeChat on their subjective well-being (SWB) in terms of intensity. In addition, we confirmed the mediating effects of WeChat with respect to motivation. The results showed that the participants' WeChat use intensity was at a mid-level, 85.3 percent of them spending no more than 2 hours on WeChat every day. Furthermore, there have been no demographic differences in the variables of gender, place of residence, or grade. Participants' WeChat use intensity can significantly predict their use motivation and life satisfaction, and intrinsic use motivation was the mediator between the use intensity and SWB, while the other three types of motivation (external, introjection, and identification) cannot predict SWB significantly. The user's ultimate emotional experience is primarily derived from why and how they use it. We also tested whether the use motivation can be shaped.

In China, the number of college students using mobile phone based messaging and social networking applications like WeChat is increasing rapidly. However, there has been minimal research into the addictive nature of these applications and the psychological characteristics associate with their excessive use. There is also no published scale available for assessing excessive use of WeChat and similar applications. In the current study, we collected data from 1,245 college students in China (715 females) and developed the WeChat Excessive Use Scale (WEUS). We then assessed the relationship between excessive use of WeChat and excessive use of a social networking application-Weibo, problematic use of mobile phones, external locus of control, and social interaction skills. Our 10-item scale featured three factors, namely- "mood modification," "salience" and ''conflict"- critical factors in assessing different forms of addiction. The WEUS was found to be a reliable instrument in assessing excessive use of WeChat as it showed good internal consistency and correlated with other measures of problematic use social networking and mobile phone addiction. Our results showed that excessive users of WeChat are more likely to excessively use Weibo than they are to problematically use mobile phones. Our study also showed that greater excessive use of WeChat is associated with higher external locus of control and greater online social interaction skills. These results reveal that WeChat has unique and strong appeal among college students in China. Further, practitioners should consider dealing with malleable factors like locus of control and real life social skills in treating people with problematic messaging and social networking.

Objective: To explore influence of the WeChat platform on the compliance of continuous treatment of scar in adult burn patients. Methods: A total of 124 adult burn patients, conforming to the study criteria, admitted in the Department of Burns of our hospital from January 2015 to January 2016 were divided into WeChat group ( n =63) and control group ( n =61) according to the random number table. Patients in control group only received regular discharging rehabilitation guide, while patients in WeChat group received regular discharging rehabilitation guide and joined WeChat platform after being discharged from hospital. Through pushing rehabilitation plan and rehabilitation related knowledge, organizing support discussion of burn patients, answering the patients' questions, members of WeChat platform intervention group conducted continuous treatment for 6 months on patients of WeChat group. The compliance of functional exercise of patients in two groups in one week before discharge and 3 and 6 months after discharge was evaluated by using the self-made functional exercise compliance log sheet. The compliance of using anti-scar drug and appliance of patients in two groups in 3 and 6 months after discharge was evaluated by using self-made anti-scar drug and appliance usage log sheets. Data were processed with chi-square test, independent sample t test, non-parametric rank sum test of independent sample, and Wilcoxon rank sum test. Results: (1) The compliance ratio of functional exercise of patients in WeChat group (95.24%, 60/63) was close to 93.44% (57/61) in control group in one week before discharge ( χ (2)=0.188, P >0.05). The compliance ratios of functional exercise of patients in WeChat group were respectively 93.65% (59/63) and 87.30% (55/63) in 3 and 6 months after discharge, which were higher than 68.85% (42/61) and 65.57% (40/61) in control group ( χ (2)=12.615, 8.166, P WeChat group was significantly better than that in control group in 3 and 6 months

The Internet hospital, an innovative approach to providing health care, is rapidly developing in China because it has the potential to provide widely accessible outpatient service delivery via Internet technologies. To date, China's Internet hospitals have not been systematically investigated. The aim of this study was to describe the characteristics of China's Internet hospitals, and to assess their health service capacity. We searched Baidu, the popular Chinese search engine, to identify Internet hospitals, using search terms such as "Internet hospital," "web hospital," or "cloud hospital." All Internet hospitals in mainland China were eligible for inclusion if they were officially registered. Our search was carried out until March 31, 2017. We identified 68 Internet hospitals, of which 43 have been put into use and 25 were under construction. Of the 43 established Internet hospitals, 13 (30%) were in the hospital informatization stage, 24 (56%) were in the Web ward stage, and 6 (14%) were in full Internet hospital stage. Patients accessed outpatient service delivery via website (74%, 32/43), app (42%, 18/43), or offline medical consultation facility (37%, 16/43) from the Internet hospital. Furthermore, 25 (58%) of the Internet hospitals asked doctors to deliver health services at a specific Web clinic, whereas 18 (42%) did not. The consulting methods included video chat (60%, 26/43), telephone (19%, 8/43), and graphic message (28%, 12/43); 13 (30%) Internet hospitals cannot be consulted online any more. Only 6 Internet hospitals were included in the coverage of health insurance. The median number of doctors available online was zero (interquartile range [IQR] 0 to 5; max 16,492). The median consultation fee per time was ¥20 (approximately US $2.90, IQR ¥0 to ¥200). Internet hospitals provide convenient outpatient service delivery. However, many of the Internet hospitals are not yet mature and are faced with various issues such as online doctor scarcity and

The Internet is fast gaining recognition as a powerful, low-cost method to deliver health intervention and prevention programs to large numbers of young people across diverse geographic regions. The feasibility and accessibility of Internet-based health interventions in resource-limited settings, where cost-effective interventions are most needed, is unknown. To determine the utility of developing technology-based interventions in resource-limited settings, availability and patterns of usage of the Internet first need to be assessed. The Uganda Media and You Survey was a cross-sectional survey of Internet use among adolescents (ages 12-18 years) in Mbarara, Uganda, a municipality mainly serving a rural population in sub-Saharan Africa. Participants were randomly selected among eligible students attending one of five participating secondary day and boarding schools in Mbarara, Uganda. Of a total of 538 students selected, 93% (500) participated. Of the total respondents, 45% (223) reported ever having used the Internet, 78% (175) of whom reported going online in the previous week. As maternal education increased, so too did the odds of adolescent Internet use. Almost two in five respondents (38% [189]) reported already having used a computer or the Internet to search for health information. Over one-third (35% [173]) had used the computer or Internet to find information about HIV/AIDS, and 20% (102) had looked for sexual health information. Among Internet users, searching for HIV/AIDS information on a computer or online was significantly related to using the Internet weekly, emailing, visiting chat rooms, and playing online games. In contrast, going online at school was inversely related to looking for HIV/AIDS information via technology. If Internet access were free, 66% (330) reported that they would search for information about HIV/AIDS prevention online. Both the desire to use, and the actual use of, the Internet to seek sexual health and HIV/AIDS information is

There were statistical differences between departments (p<0.05. The internet addiction score of students of Faculty of Science and Literature, School of Health and Theology was significantly lower than other sections. internet addiction scores were higher in males (p<0.05. In terms of personality characteristics of participants, it was found that they had a higher score (3.9±1.8 in the "Outward Turnover". It was determined that there is a statistically positive relationship between internet addiction score and Neurotism, Psychotism but the negative relationship with the "Lie" personality sub-dimensions. Conclusion: Internet dependency score was found low in this study. Although this is a desirable situation, it would be useful to ensure participation of students in the recreational activities to protect this situation.

Full Text Available The youth of today lives in the midst of a technological revolution, particularly in the field of communications (e-chats, mobile telephones, Messenger, etc.. In many parts of Spain, the Internet has overtaken television, not only as a source of entertainment and recreation among teenagers, but also as a socialisation force. Adolescents suffering from Attention-Deficit Hyperactivity Disorder (ADHD have specific characteristics that may make them more vulnerable when using new technologies. Consequently, it is important to investigate the ways in which these teenagers use the Internet. This study attempts to identify, through the application of the Television Viewing Habits Questionnaire CH-TV 0.2, the possible differences between teenagers with ADHD and normal teenagers, with regards to Internet use, purpose of use, and parental mediation. The results, which are based on a sample of 232 adolescents from the Basque Country (Spain, indicate differences in Internet use profiles between adolescents with ADHD and the normal adolescent population. Contrary to our hypothesis, the former group uses the Internet less than the latter. Furthermore, despite the fact that for both sample groups the principal purpose of using the Internet was communication, significant differences were detected. In relation to parental mediation, teenagers with ADHD reported a higher degree of instructive and restrictive mediation.

The aims of this cross-sectional study were to examine the associations of suicidal ideation and attempt with Internet addiction and Internet activities in a large representative Taiwanese adolescent population. 9510 adolescent students aged 12-18 years were selected using a stratified random sampling strategy in southern Taiwan and completed the questionnaires. The five questions from the Kiddie Schedule for Affective Disorders and Schizophrenia were used to inquire as to the participants' suicidal ideation and attempt in the past one month. The Chen Internet Addiction Scale was used to assess participants' Internet addiction. The kinds of Internet activities that the adolescents participated in were also recorded. The associations of suicidal ideation and attempt with Internet addiction and Internet activities were examined using logistic regression analysis to control for the effects of demographic characteristics, depression, family support and self-esteem. After controlling for the effects of demographic characteristics, depression, family support and self-esteem, Internet addiction was significantly associated with suicidal ideation and suicidal attempt. Online gaming, MSN, online searching for information, and online studying were associated with an increased risk of suicidal ideation. While online gaming, chatting, watching movies, shopping, and gambling were associated with an increased risk of suicidal attempt, watching online news was associated with a reduced risk of suicidal attempt. The results of this study indicated that adolescents with Internet addiction have higher risks of suicidal ideation and attempt than those without. Meanwhile, different kinds of Internet activities have various associations with the risks of suicidal ideation and attempt. Copyright © 2014 Elsevier Inc. All rights reserved.

Full Text Available Abstract Background The Internet provides a new meeting ground, especially for gay men, that did not exist in the early 1990s. Several studies have found increased levels of high risk sexual behaviour and sexually transmissible infections (STI among gay men who seek sex on the Internet, although the underlying processes are not fully understood. Research funded by the UK Medical Research Council (2002–2004 provided the opportunity to consider whether the Internet represents a new sexual risk environment for gay and bisexual men living in London. Methods The objectives of the Internet and HIV study are to: (i measure the extent to which gay men living in London seek sexual partners on the Internet; (ii compare the characteristics of London gay men who do and do not seek sex on the Internet; (iii examine whether sex with Internet-partners is less safe than with other sexual partners; (iv compare use of the Internet with other venues where men meet sexual partners; (v establish whether gay men use the Internet to actively seek partners for unprotected anal intercourse; (vi determine the potential for using the Internet for HIV prevention. These objectives have been explored using quantitative and qualitative research methods in four samples of London gay men recruited and interviewed both online and offline. The four samples were: (i gay men recruited through Internet chat rooms and profiles; (ii HIV positive gay men attending an NHS hospital outpatients clinic; (iii gay men seeking an HIV test in an NHS HIV testing or sexual health clinic; (iv gay men recruited in the community. Results Quantitative data were collected by means of confidential, anonymous self-administered questionnaires (n>4000 completed on-line by the Internet sample. Qualitative data were collected by means of one-to-one interviews (n = 128 conducted either face-to-face or on-line. Conclusion The strength of the Internet and HIV study is its methodological plurality, drawing

Full Text Available Introduction: The internet is an important modern means of obtaining information and communicating with others which has converted the world into a global village. At the same time, increasing internet use among adolescents is also likely to pose a major public health concern that is internet addiction (IA. The aim was to assess the prevalence of IA among school-going adolescents and factors associated with IA. Methods: A cross-sectional study was designed to survey adolescents studying in 8th to 11th standard of five schools of Vadodara. Information regarding sociodemography and various patterns of internet use were obtained using survey forms. IA test (IAT was used to screen for IA. Descriptive analysis, univariate analysis, and logistic regression were done to analyze the data. Results: Seven hundred and twenty-four participants that completed IAT were analyzed. Internet use prevalence was 98.9%. Prevalence of IA was 8.7%. Male gender, owning a personal device, hours of internet use/day, use of smartphones, permanent login status, use of internet for chatting, making online friends, shopping, watching movies, online gaming, searching information online and instant messaging were found to be associated significantly with IA in univariate analysis. Internet use for online friendships was found to be a significant predictor of IA (odds ratio [OR] =2.4, and internet use for searching information was found to be protective (OR = 0.20 against IA on logistic regression. Conclusions: IA is prevalent in the adolescent population and requires awareness and intervention. Characteristics of internet usage found to be associated with IA needs to be considered while developing strategies for interventions.

Full Text Available With the overreaching acceptance of ICT in education and access to Internet occasioned by advancement in technology, this paper investigates pre-service teachers’ use of Internet in a college of education. The study was a descriptive survey. Data was collected using a researcher designed instrument tagged “Student Internet Use Scale” (SIUS. The population comprised of all NCE pre-service teachers in Alvan Ikoku Federal College of Education Owerri Nigeria. Findings show that  mobile phones remains the most widely used mode of internet access with social networking, searching for information on school assignments, chatting forming the major reasons why they surf the net. Social networking is the major purpose for Internet use by female pre-service teachers while school related activities are of priority to males. The difference in purpose of internet use according to gender is however not statistically significant; similarly, there is no statically significant difference between male and female pre-service teachers in the frequency of Internet usage. The result has far reaching implication for provision and use of Internet facilities to enhance teaching and learning in the College and colleges of education in Nigeria.

Essay: The Yi and the Internet: Promoting Ethnicity and Ethnic Identity in Chinese Virtuality

Directory of Open Access Journals (Sweden)

Kraef, Olivia

2013-03-01

Full Text Available Since the turn of the century China has witnessed an unparalleled development of internet sites, blogs, chat forums, and corresponding virtual communities. These virtual platforms have become important nodes for information and networking, especially in light of economic and intellectual migration and the corresponding trans-local quality of relationships and networks, and contribute to a further diversification of China’s cultural landscape. China’s ethnic minorities, too, have been employing internet platforms as a means to promote, and to reflect on, their own culture. For some groups these platforms signify an extension of early, non-virtual ethnic networks and platforms in urban contexts, which provide a renewed incentive for the affirmation of ethnicity/ethnic identity by engaging netizens in an ongoing dialogue on ethnic cultural contents, which transcends physical space. The article introduces two major internet platforms of the so-called Yi minority, www.yizuren.com and http://yizucn.com, and probes into their potential for ethnic identity promotion, and into general parameters of the relationship between the Yi and the internet.

The Changing Physical and Social Environment of Newsgathering: A Case Study of Foreign Correspondents Using Chat Apps During Unrest

Directory of Open Access Journals (Sweden)

Valerie Belair-Gagnon

2017-03-01

Full Text Available Mobile chat apps have shaped multiple forms of communication in everyday life, including education, family, business, and health communication. In journalism, chat apps have taken on a heightened significance in reporting political unrest, particularly in terms of audience/reporter distinctions, sourcing of information, and community formation. Mobile phones are now essential components in reporters’ everyday communication, and particularly during political unrest. In East Asia, the latest trends point toward private networking apps, such as WeChat and WhatsApp, as the most important digital tools for journalists to interact with sources and audiences in news production. These apps provide a set of private (and, increasingly, encrypted alternatives to open, public-facing social media platforms. This article is the first to examine foreign correspondents’ usage of chat apps for newsgathering during political unrest in China and Hong Kong since the 2014 “Umbrella Movement,” a time when the use of chat apps in newsgathering became widespread. This article identifies and critically examines the salient features of these apps. It then discusses the ways these journalistic interactions on chat apps perpetuate, disrupt, and affect “social” newsgathering. This article argues that chat apps do not represent one interactive space; rather they are hybrid interactions of news production embedded in social practices rather than pre-existing physical/digital spaces. This research is significant as the emergence of chat apps as tools in foreign correspondents’ reporting has implications for journalistic practices in information gathering, storage, security, and interpretation and for the informational cultures of journalism.

The energy consumption of the air-conditioning system at the Internet Data Center (IDC) in Beijing comprises 40 per cent of the building's total energy consumption. Of all the energy energy management strategies available at the IDC, the most unique one is the use of ambient energy to cool the IDC by the thermosyphon heat exchanger. Atmospheric energy can reduce the air conditioner's running time while maintaining the humidity and cleanliness of the IDC. In this study, an IDC test model was set up to analyze the heat dissipating characteristics and the energy consumption of the thermosyphon heat exchanger and the air conditioner in the IDC for winter conditions. The heat dissipating capacity of the building envelope was measured and calculated. The energy consumption of the air conditioner was compared under different indoor and outdoor temperatures. The study showed that the heat dissipating need of the IDC cannot be met just by the heat dissipation of the building envelope in winter conditions. The heat dissipating capacity of the IDC building envelope comprises 19.5 per cent of the total heat load. The average energy consumption of the air conditioner is 3.5 to 4 kWh per day. The temperature difference between indoor and outdoor temperature in the IDC with the thermosyphon heat exchanger was less than 20 degrees C, and the energy consumption of the thermosyphon heat exchanger comprised only 41 per cent of that of the air conditioner. 8 refs., 1 tab., 8 figs.

Exploring patients' computer and internet use, their expectations and attitudes is mandatory for successful introduction of interactive online health-care applications in Angiology. We included 165 outpatients suffering from peripheral arterial disease (PAD; n = 62) and chronic venous and / or lymphatic disease (CVLD; n = 103) in a cross-sectional-study. Patients answered a paper-based questionnaire. Patients were predominantly female (54.5%). 142 (86.1%) reported regular computer use for 9.7 +/- 5.8 years and 134 (81.2 %) used the internet for 6.2 +/- 3.6 years. CVLD-patients and internet-user were younger and higher educated, resulting in a significant difference in computer and internet use between the disease groups (p internet users without significant differences between the groups. The topics retrieved from the internet covered a wide spectrum and searches for health information were mentioned by 41.2 %. Although confidence in the internet (3.3 +/- 1.1 on a 1-6 Likert scale) and reliability in information retrieved from the internet (3.1 +/- 1.1) were relatively low, health-related issues were of high actual and future interest. 42.8% of the patients were even interested in interactive applications like health educational programs, 37.4% in self-reported assessments and outcome questionnaires and 26.9% in chatforums; 50% demanded access to their medical data on an Internetserver. Compared to older participants those internet more often for shopping, chatting, and e-mailing, but not for health information retrieval and interactive applications. Computers are commonly used and the internet has been adopted as an important source of information by patients suffering from PAD and CVLD. Besides, the internet offers great potentials and new opportunities for interactive disease (self-)management in angiology. To increase confidence and reliability in the medium a careful introduction and evaluation of these new online applications is mandatory.

Background Being overweight and obese are major risk factors for noncommunicable diseases such as cardiovascular diseases. The prevalence of overweight and obesity is high throughout the world and these issues are very serious in the Shunyi District in China. As mobile technologies have rapidly developed, mobile apps such as WeChat are well accepted and have the potential to improve health behaviors. Objective This study aims to evaluate the effectiveness of a mobile app (WeChat) as an intervention on weight loss behavior. Methods This study was conducted among an occupational population from August 2015 to February 2016 in the Shunyi District of Beijing. Before the intervention, the Shunyi District Government released an official document for weight loss to all 134 government agencies and enterprises in Shunyi District. Participants willing to use our official WeChat account were enrolled in a WeChat group and received 6 months of interventions for weight loss; those who were not willing to use the account were in a control group given routine publicity on weight loss. Results In total, 15,310 occupational participants including 3467 participants (22.65%) in the control group and 11,843 participants (77.35%) in the WeChat group were enrolled. Participants in the WeChat group lost more weight (mean 2.09, SD 3.43 kg) than people in the control group (mean 1.78, SD 2.96 kg), and the difference in mean weight loss between the two groups for males was significant based on the stratification of age and educational level. To control for confounding factors and to explore the effects of WeChat on weight loss, the propensity score method with a multinominal logistic regression was utilized. For males, this showed that the WeChat group (with both active and inactive subgroups) had a higher probability of maintaining weight, weight loss from 1 to 2 kg, or weight loss more than 2 kg than the control group. However, the control group had higher probability of weight loss from

David B. Nicholas PhD

2010-03-01

Full Text Available In this study the authors examined Internet-mediated qualitative data collection methods among a sample of children with chronic health conditions. Specifically, focus groups via Internet technology were contrasted to traditional face-to-face focus groups. Internet focus groups consisted of asynchronous text-based chat rooms lasting a total of one week in duration. Participants comprised 23 children with cerebral palsy, spina bifida, or cystic fibrosis, who were assigned to either an Internet or face-to-face focus group. Focus group analysis and follow-up participant interviews identified a range of content outcomes and processes as well as participant experiences and preferences. Findings yielded differences in terms of the volume and nature of online and face-to-face data, and participants' affinity to focus group modality appeared to reflect differences in participant expectations for social engagement and interaction. This study identifies both benefits and limitations of asynchronous, text-based online focus groups. Implications and recommendations are discussed.

In October 2007, the working group CEN/TC 216 of the European Committee for standardisation suggested that the Sabin oral poliovirus vaccine type 1 strain (LSc-2ab) presently used for virucidal tests should be replaced by another attenuated vaccine poliovirus type 1 strain, CHAT. Both strains were historically used as oral vaccines, but the Sabin type 1 strain was acknowledged to be more attenuated. In Germany, vaccination against poliomyelitis was introduced in 1962 using the oral polio vaccine (OPV) containing Sabin strain LSc-2ab. The vaccination schedule was changed from OPV to an inactivated polio vaccine (IPV) containing wild polio virus type 1 strain Mahoney in 1998. In the present study, we assessed potential differences in neutralising antibody titres to Sabin and CHAT in persons with a history of either OPV, IPV, or OPV with IPV booster. Neutralisation poliovirus antibodies against CHAT and Sabin 1 were measured in sera of 41 adults vaccinated with OPV. Additionally, sera from 28 children less than 10 years of age and immunised with IPV only were analysed. The neutralisation assay against poliovirus was performed according to WHO guidelines. The neutralisation activity against CHAT in adults with OPV vaccination history was significantly lower than against Sabin poliovirus type 1 strains (Wilcoxon signed-rank test P Sabin 1 varied between 8 and 64. Following IPV booster, anti-CHAT antibodies increased rapidly in sera of CHAT-negative adults with OPV history. Sera from children with IPV history neutralised CHAT and Sabin 1 strains equally. The lack of neutralising antibodies against the CHAT strain in persons vaccinated with OPV might be associated with an increased risk of reinfection with the CHAT polio virus type 1, and this implies a putative risk of transmission of the virus to polio-free communities. We strongly suggest that laboratory workers who were immunised with OPV receive a booster vaccination with IPV before handling CHAT in the laboratory.

Research trying to understand individual difference in the use of different social networking sites (SNSs) is minimal. In the present study, we collected data from 714 college students in China (273 males) to assess how personality traits and psychological factors relate to excessive use of WeChat and Weibo. We found that excessive use of Weibo and WeChat correlated positively with neuroticism, loneliness, and external locus of control and negatively with agreeableness, social support, and social interaction. Furthermore, people that scored high on loneliness, lack of social support, and poor social interaction skills excessively used Weibo more than WeChat. These results entail that by fulfilling different needs, WeChat and Weibo attract different kinds of people; significant lesson for future development of SNSs. PMID:29755384

Smith, S. Jerrod

2013-01-01

From the 1890s through the 1970s the Picher mining district in northeastern Ottawa County, Oklahoma, was the site of mining and processing of lead and zinc ore. When mining ceased in about 1979, as much as 165–300 million tons of mine tailings, locally referred to as “chat,” remained in the Picher mining district. Since 1979, some chat piles have been mined for aggregate materials and have decreased in volume and mass. Currently (2013), the land surface in the Picher mining district is covered by thousands of acres of chat, much of which remains on Indian trust land owned by allottees. The Bureau of Indian Affairs manages these allotted lands and oversees the sale and removal of chat from these properties. To help the Bureau of Indian Affairs better manage the sale and removal of chat, the U.S. Geological Survey, in cooperation with the Bureau of Indian Affairs, estimated the 2005 and 2010 volumes and masses of selected chat piles remaining on allotted lands in the Picher mining district. The U.S. Geological Survey also estimated the changes in volume and mass of these chat piles for the period 2005 through 2010. The 2005 and 2010 chat-pile volume and mass estimates were computed for 34 selected chat piles on 16 properties in the study area. All computations of volume and mass were performed on individual chat piles and on groups of chat piles in the same property. The Sooner property had the greatest estimated volume (4.644 million cubic yards) and mass (5.253 ± 0.473 million tons) of chat in 2010. Five of the selected properties (Sooner, Western, Lawyers, Skelton, and St. Joe) contained estimated chat volumes exceeding 1 million cubic yards and estimated chat masses exceeding 1 million tons in 2010. Four of the selected properties (Lucky Bill Humbah, Ta Mee Heh, Bird Dog, and St. Louis No. 6) contained estimated chat volumes of less than 0.1 million cubic yards and estimated chat masses of less than 0.1 million tons in 2010. The total volume of all

Can human-like Bots control collective mood: agent-based simulations of online chats

Science.gov (United States)

Tadić, Bosiljka; Šuvakov, Milovan

2013-10-01

Using an agent-based modeling approach, in this paper, we study self-organized dynamics of interacting agents in the presence of chat Bots. Different Bots with tunable ‘human-like’ attributes, which exchange emotional messages with agents, are considered, and the collective emotional behavior of agents is quantitatively analyzed. In particular, using detrended fractal analysis we determine persistent fluctuations and temporal correlations in time series of agent activity and statistics of avalanches carrying emotional messages of agents when Bots favoring positive/negative affects are active. We determine the impact of Bots and identify parameters that can modulate that impact. Our analysis suggests that, by these measures, the emotional Bots induce collective emotion among interacting agents by suitably altering the fractal characteristics of the underlying stochastic process. Positive emotion Bots are slightly more effective than negative emotion Bots. Moreover, Bots which periodically alternate between positive and negative emotion can enhance fluctuations in the system, leading to avalanches of agent messages that are reminiscent of self-organized critical states.

Collective emotion dynamics in chats with agents, moderators and Bots

M. Šuvakov

2014-09-01

Full Text Available Using agent-directed simulations, we investigate fluctuations in the collective emotional states on a chat network where agents interchange messages with a fixed number of moderators and emotional Bot. To design a realistic chat system, the interaction rules and some statistical parameters, as well as the agent's attributes, are inferred from the empirical chat channel Ubuntu. In the simulations, the Bot's emotion is fixed; the moderators tune the level of its activity by passing a fraction ε of messages to the Bot. At ε ≥ 0, the collective emotional state matching the Bot's emotion polarity gradually arises; the average growth rate of the dominant emotional charge serves as an order parameter. Due to self-organizing effects, the collective dynamics is more explosive when positive emotions arise by positive Bot than the onset of negative emotions in the presence of negative Bot at the same ε. Furthermore, when the emotions matching the Bot's emotion polarity are spread over the system, the underlying fractal processes exhibit higher persistence and stronger clustering of events than the processes spreading of emotion polarity opposite to the Bot's emotion. On the other hand, the relaxation dynamics is controlled by the external noise; the related nonextensive parameter, estimated from the statistics of returns, is virtually independent of the Bot's activity level and emotion contents.

Problematic internet use is on the increase and has caused serious problems in many areas. This issue seems to be more important for medical students. This study was designed to explore the prevalence of internet addiction and its related factors among the students of Mashhad University of Medical Sciences. A cross sectional study was conducted on 383 medical students of Mashhad in 2013. Four hundred participants were selected through two-stage stratified sampling method proportional to the number of students in each stage of education. Data Collection was done through using the Chen Internet Addiction Scale (CIAS) and a checklist of demographic details and characteristics of internet usage behavior. It was found that 2.1% of the studied population were at risk and 5.2% were addicted users. Chatting with new people, communicating with friends and families, and playing games were the most popular activities in these groups. The factors related to internet addiction included: male sex, stage of education, daily time spent on using internet, most frequent time of internet use, monthly cost of use, and tea consumption. Although our study showed the prevalence of internet addiction was not more than other populations and universities, since the prevalence of internet addiction is rapidly increasing worldwide, this population might also be at risk of addiction. Thus, focusing on related factors can help us in designing more effective interventions and treatments for this susceptible group.

Paralleling the rapid growth in computers and internet connections, adolescent internet addiction (AIA) is becoming an increasingly serious problem, especially in developing countries. This study aims to explore the prevalence of AIA and associated symptoms in a large population-based sample in Shanghai and identify potential predictors related to personal characteristics. In 2007, 5,122 adolescents were randomly chosen from 16 high schools of different school types (junior, senior key, senior ordinary and senior vocational) in Shanghai with stratified-random sampling. Each student completed a self-administered and anonymous questionnaire that included DRM 52 Scale of Internet-use. The DRM 52 Scale was adapted for use in Shanghai from Young's Internet Addiction Scale and contained 7 subscales related to psychological symptoms of AIA. Multiple linear regression and logistic regression were both used to analyze the data. Of the 5,122 students, 449 (8.8%) were identified as internet addicts. Although adolescents who had bad (vs. good) academic achievement had lower levels of internet-use (p 100 RMB (all p-values internet addicts overused internet on weekends than on weekdays, p internet mainly for playing games or real-time chatting. This study provides evidence that adolescent personal factors play key roles in inducing AIA. Adolescents having aforementioned personal characteristics and online behaviors are at high-risk of developing AIA that may compound different psychological symptoms associated with AIA. Spending excessive time online is not in itself a defining symptom of AIA. More attention is needed on adolescent excessive weekend internet-use in prevention of potential internet addicts.

Full Text Available Research trying to understand individual difference in the use of different social networking sites (SNSs is minimal. In the present study, we collected data from 714 college students in China (273 males to assess how personality traits and psychological factors relate to excessive use of WeChat and Weibo. We found that excessive use of Weibo and WeChat correlated positively with neuroticism, loneliness, and external locus of control and negatively with agreeableness, social support, and social interaction. Furthermore, people that scored high on loneliness, lack of social support, and poor social interaction skills excessively used Weibo more than WeChat. These results entail that by fulfilling different needs, WeChat and Weibo attract different kinds of people; significant lesson for future development of SNSs.

Full Text Available Objective: Young people seem particularly likely to develop pathological Internet use (PIU with the use of social networks, chat, and videos. Sensation-seeking, neuroticism, introversion, and low self-esteem are personality features frequently associated with the disease. The aim of this study was to replicate and to extend previous findings by exploring the combined effect of personality traits and self-esteem on PIU. Method: A sample of 652 male students attending vocational technical schools in Palermo (Southern Italy was assessed using the following measures: the Zuckerman-Kuhlman Personality Questionnaire to evaluate personality traits; the Multidimensional Self-Concept Scale to assess self-esteem; the Tech Style Behavior to investigate PIU. Results: Pathological Internet Use was associated to age, feelings of low self-esteem and inadequate competence, impulsivity/sensation seeking, aggression-hostility, and sociability. However, in a multiple linear regression model, only sociability, aggression-hostility, competence, and age demonstrated a significant effect in the prediction of PIU. Conclusions: Expanding previous research, the findings suggest that low self-esteem, high aggression-hostility, and high sociability are significant risk factors for PIU. Therefore, primary prevention programmes should include interventions aimed at promoting self-competence, enhancing emotional skills, and developing effective coping strategies.

Novel psychoactive substances (NPS) are continuously and increasingly appearing on the international drug market. Global Internet forums are a publicly available reality where users anonymously discuss and share information about NPS. The aim of this study was to explore and characterize the discussions about NPS on international Internet forums. The most post-frequent NPS discussions were collected from three "leading edge" international Internet forums. A total of 13,082 posts from 60 threads of discussion were systematically examined and interpreted to reveal recurring topics and patterns. Each thread was coded with emerging topics and supporting quotations from the data set. Eventually, codes with coherent meaning were arranged into 51 broader categories of abstraction, which were combined into four overarching themes. Four themes emerged during the analysis: (1) uncovering the substance facts, (2) dosage and administration, (3) subjectively experienced effects, and (4) support and safety. The first theme dealt primarily with substance identification, pharmacology, and assessed not only purity but also legal status and acquisition. The second theme focused on administration techniques, dose recommendations, technical talk about equipment, and preferred settings for drug use. The third theme involved a multitude of self-reported experiences, in which many different aspects of intoxication were depicted in great detail. The users emphasized both positive and negative experiences. The last theme incorporated the efforts of the communities to prevent and minimize harm by sharing information about potential risks of the harmful effects or contraindications of a substance. Also, online support and guidance were given to intoxicated persons who experienced bad or fearful reactions. The findings showed that the discussions were characterized by a social process in which users supported each other and exchanged an extensive and cumulative amount of knowledge about NPS

Perfume formulation: words and chats.

Science.gov (United States)

Ellena, Céline

2008-06-01

What does it mean to create fragrances with materials from chemistry and/or from nature? How are they used to display their characteristic differences, their own personality? Is it easier to create with synthetic raw materials or with essential oils? This review explains why a perfume formulation corresponds in fact to a conversation, an interplay between synthetic and natural perfumery materials. A synthetic raw material carries a single information, and usually is very linear. Its smell is uniform, clear, and faithful. Natural raw materials, on the contrary, provide a strong, complex and generous image. While a synthetic material can be seen as a single word, a natural one such as rose oil could be compared to chatting: cold, warm, sticky, heavy, transparent, pepper, green, metallic, smooth, watery, fruity... full of information. Yet, if a very small amount of the natural material is used, nothing happens, the fragrance will not change. However, if a large amount is used, the rose oil will swallow up everything else. The fragrance will smell of nothing else except rose! To formulate a perfume is not to create a culinary recipe, with only dosing the ingredients in well-balanced amounts. To formulate rather means to flexibly knit materials together with a lively stitch, meeting or repelling each other, building a pleasant form, which is neither fixed, nor solid, nor rigid. A fragrance has an overall structure, which ranges from a clear sound, made up of stable, unique, and linear items, to a background chat, comfortable and reassuring. But that does, of course, not mean that there is only one way of creating a fragrance!

This study examined the effects of WeChat-assisted perioperative instructions for parents whose children were to undergo herniorrhaphy. A randomized controlled trial was conducted in a day surgery center in China. Participants were randomly assigned to the intervention (WeChat) group (n = 209) and the control (Leaflet) group (n = 209). The primary outcomes of this study were parents' knowledge regarding hernia and rate of cancellation of children's surgery. The secondary outcomes were the rate of lost-to-follow-up and the rate of complications and adverse events during the seventh postoperative follow-up day. There was a significant difference in the rate of cancelling the surgery and the mean knowledge score between the WeChat group and leaflet groups. The lost-to-follow-up rate was significantly lower in the WeChat group (0.54%) than in the leaflet group (3.66%). The incidence of postoperative complications were higher in the control group. WeChat-assisted perioperative care instructions enhanced parents' knowledge on perioperative instructions and promoted the preparation of their children for day surgery resulting in lower rate of cancelling the surgery. WeChat has the ability to expand health services outside the hospital confines and could be used as an important low-cost health educational medium in China. Copyright © 2018 Elsevier B.V.

Saele, Hanne; Graabak, Ingeborg; Tangen, Grethe

2000-01-01

The two-way communication towards the end consumer is in little use so far. There are probably several reasons for this but one important reason may be the lack of standardized interfaces for the information exchange towards the end user. The lack of such standards results in substantial system investment risks for the network companies because the systems may not be developed further and maintained should the deliverer leave the market. The communication channel Internet has expanded quickly and in Norway of today (1999) 25 to 30 % of the households have an Internet connection. The use of existing infrastructure and already tried out technology for information transferrals may contribute to making two-way communication more reasonable and functional. In the report various alternatives of standardized information exchange towards the end users are evaluated. Various formats are discussed with the following demands in mind: 1) Shall be suited for all types of communication media. 2) An international standard followed by everyone. 3) Reliable information transferral and flexible. The focus is on what kind of information is being transferred and how this is organized, and not on how the information is transferred. The discussed alternatives are evaluated both regarding traditional solutions for two- way communication and the use of the Internet. The following format alternatives are discussed: EDIEL/EDIFACT, ODEL(GS2), LonWorks/Echelon, UCA, DLMS/COSEM, COBRA and DCOM. The formats represent communication at various levels but they are mentioned in the report because they are often mentioned as possible standard formats towards the end user: ODEL, DLSM/COSEM and UCA. EDIEL is not suited for this interface. The market for two-way communication systems is international and it does not seem to be practical to establish a joint Norwegian/Swedish standard. The work with establishing one standard should therefore be continued through international standardization

Full Text Available Changes in the last 10 years in information technology have increased the use of computers and internet. The changes brought about fundamental changes the way we do business and behave in social life from communication and reaching information to daily habits. Effective use of the information technology, which has become the main condition of being competitive at work, has required all employees in public and private sectors to improve themselves in the computer and internet usage. In addition, the public sector also encourages the use of internet via e-government applications. Thus, the computers and internet play a big part in the work of public sector and its employees as well. The usage of computers and the internet in working places not only have changed the way we do business also have changed some ethical rules and issues. They brought some complicated problems for people, organizations and states. Online fraud, carelessness, negligence, viruses, system crashing, broadcasting personal information are among the most well-known ethical problems related to computers and internet and caused by employees. In addition to these, personal use of computers and internet by employees for their private usage during working hours create another problem. The objective of the study is to reveal the internet usage habits and behaviors of public employees at work, using a field research that was carried out in Kastamonu that is a city of north of Turkey. It is especially of interest how and for what purposes the chat programs, which encourage the use of internet, are used. The results are analyzed from the point of view of public ethics. The data is collected from the state servants in Kastamonu and is analyzed on SPSS statistic program.

This study aimed to measure the prevalence of Problematic Internet Use (PIU) among high school students and to identify factors associated with PIU underlining gender differences. The students filled a self-administered, anonymous questionnaire collecting information on demographic characteristics and patterns of Internet use. Multiple logistic regression analysis was performed to identify factors associated with PIU in the overall sample and by gender. Twenty-five schools and 2022 students participated in the survey. Prevalence of PIU was 14.2% among males and 10.1% among females. Males 15-year-olds and females 14-year-olds had the highest PIU prevalence that progressively lowered with age among females. Only 13.5% of pupils declared parents controlled their Internet use. The sensation of feeling lonely, the frequency of use, the number of hours of connection, and visiting pornographic websites were associated with the risk of PIU in both genders. Attending vocational schools, the activities of chatting and file downloading, and the location of use at Internet point among males, and younger age among females were associated with PIU, whilst information searching was protective among females. PIU could become a public health problem in the next years. The physical and mental health consequences should be studied. Copyright © 2017 Elsevier B.V. All rights reserved.

2016-01-01

Illness is a ubiquitous experience in all societies. Until the past two decades, illness remained largely a private experience. With the development of the Internet, especially what has been termed Web 2.0, with interactive websites, illness has become increasingly a public experience. Vehicles like bulletin boards, chat rooms, listservs, electronic support groups, and more recently social media facilitate thousands of online communities where individuals with illness share information, interaction, experience, and advocacy. With the advent of social media, communication has increased and brought new challenges for online interaction. It is likely that the transformation of illness from a largely private to an increasingly public experience is a revolutionary change that is here to stay, with numerous social consequences. © The Author(s) 2015.

Full Text Available Voice Over the Internet Protocol (VoIP holds promise as a platform by which services can be delivered to students in rural and remote regions who have reading difficulties. VoIP is an Internet-based protocol that allows two or more individuals to videoconference from remote locations. This study used a single-case research design to investigate whether VoIP would produce significant gains in reading ability in BM, a 10-year-old with long-standing word-level reading problems. BM was provided with a theoretically motivated reading intervention 4 times weekly. The intervention was delivered remotely using the Apple iChat software. Substantial growth in regular- and nonword reading covaried with onset and removal of treatment. Treatment gains were maintained at 10-week follow-up. Meaningful gains were also seen in text-reading accuracy and reading comprehension. VoIP-based instruction represents an important avenue for future research and is a teaching method that holds much promise for rural and remote students.

Self-rated health is a brief measure for general health. It is a comprehensive and sensitive index for prediction of health in future. Due to the high internet usage in medical students, the current study designed to evaluate the self-rated health (SRH) in relationship with internet addiction risk factors in medical students. This cross sectional study conducted on 254 students of Qom University of Medical Sciences 2014. Participants selected by two stage sampling method including stratified and simple random sampling. The Young's questionnaire of internet addiction and SRH question used for data collection. Chi-square, t-test, and logistic regression used in data analysis. More than 79.9% of students reported their general health good and very good. The student's mean score of general health was higher than the average. In addition, the prevalence of internet addiction was 28.7%. An inverse significant correlation observed between SRH and internet addiction score (r=-0.198, p=0.002). Using internet for Entertainment, using private Email and chat rooms were the most important predictors of affecting to internet addiction. Moreover, internet addiction is the most predictors of SRH and increased the odds of bad SRH. The good SRH of medical students was higher than general population but in health faculty' students were lower than others. Due to the effect of internet addiction on SRH and increasing trend of internet use in medical students, as well as low age of participants, attention to psychological aspects and the job expectancy in future, can effective on increasing the good SRH.

The mind over the Web: the quest for the definition of a method for Internet research.

Riva, G

2001-02-01

Psychology is increasingly interested in understanding the characteristics of the Internet and its effects on people, groups and organizations. However, studying the Internet is not a simple task. First, the Internet is a medium that can be experienced in many different ways. Though a computer and keyboard are usually the mediator of our Internet experience, there are different ways in which users can explore the Internet, present themselves, and communicate using it. Second, the Internet is a social and cognitive space. The handling of information is linked to the activation of psychosocial relationships in which cognitions are elaborated. This happens inside a rather special kind of container--Cyberspace--which tends to rarefy the structural and process features of communication. Third, the Internet experience is always situated in a specific context, even when we are chatting alone in a room. In this sense it can only be fully understood through detailed analysis of the social context in which it happens. Starting from a general three-level model of interpersonal interaction in the Web, this paper tries to define a model of data analysis (Complementary Explorative Multilevel Data Analysis--CEMDA) suited to the constraints of Internet research. The main characteristics of the model are: the focus on different frames and objects for each considered unit of research; the mixed use of quantitative and qualitative tools; and the final integration of results in a general framework.

The use of Internet-based behavioral programs may be an efficient, flexible method to enhance prenatal care and improve pregnancy outcomes. There are few data about access to, and use of, the Internet via computers and mobile phones among pregnant women. We describe pregnant women's access to, and use of, computers, mobile phones, and computer technologies (eg, Internet, blogs, chat rooms) in a southern United States population. We describe the willingness of pregnant women to participate in Internet-supported weight-loss interventions delivered via computers or mobile phones. We conducted a cross-sectional survey among 100 pregnant women at a tertiary referral center ultrasound clinic in the southeast United States. Data were analyzed using Stata version 10 (StataCorp) and R (R Core Team 2013). Means and frequency procedures were used to describe demographic characteristics, access to computers and mobile phones, and use of specific Internet modalities. Chi-square testing was used to determine whether there were differences in technology access and Internet modality use according to age, race/ethnicity, income, or children in the home. The Fisher's exact test was used to describe preferences to participate in Internet-based postpartum weight-loss interventions via computer versus mobile phone. Logistic regression was used to determine demographic characteristics associated with these preferences. The study sample was 61.0% white, 26.0% black, 6.0% Hispanic, and 7.0% Asian with a mean age of 31.0 (SD 5.1). Most participants had access to a computer (89/100, 89.0%) or mobile phone (88/100, 88.0%) for at least 8 hours per week. Access remained high (>74%) across age groups, racial/ethnic groups, income levels, and number of children in the home. Internet/Web (94/100, 94.0%), email (90/100, 90.0%), and Facebook (50/100, 50.0%) were the most commonly used Internet technologies. Women aged less than 30 years were more likely to report use of Twitter and chat rooms

Traces of user activities recorded in online social networks open new possibilities to systematically understand the information diffusion process on social networks. From the online social network WeChat, we collected a large number of information cascade trees, each of which tells the spreading trajectory of a message/information such as which user creates the information and which users view or forward the information shared by which neighbours. In this work, we propose two heterogeneous non-linear models, one for the topologies of the information cascade trees and the other for the stochastic process of information diffusion on a social network. Both models are validated by the WeChat data in reproducing and explaining key features of cascade trees. Specifically, we apply the Random Recursive Tree (RRT) to model the growth of cascade trees. The RRT model could capture key features, i.e. the average path length and degree variance of a cascade tree in relation to the number of nodes (size) of the tree. Its single identified parameter quantifies the relative depth or broadness of the cascade trees and indicates that information propagates via a star-like broadcasting or viral-like hop by hop spreading. The RRT model explains the appearance of hubs, thus a possibly smaller average path length as the cascade size increases, as observed in WeChat. We further propose the stochastic Susceptible View Forward Removed (SVFR) model to depict the dynamic user behaviour including creating, viewing, forwarding and ignoring a message on a given social network. Beside the average path length and degree variance of the cascade trees in relation to their sizes, the SVFR model could further explain the power-law cascade size distribution in WeChat and unravel that a user with a large number of friends may actually have a smaller probability to read a message (s)he receives due to limited attention.

Connections, Information and Reality: Thinking about the internet of things

Full Text Available The number of connections between people, organizations and technology is proliferating rapidly, and the amount of information they produce, exchange and share is increasing accordingly. These connections and the information they produce are defining and shaping our daily life and work and our perception of reality. Computers in all forms are becoming smaller and less visible, but they are omnipresent. This development of information technology ‘everyware’, as Greenfield calls it, is also referred to as ubiquitous computing. With the development of ubiquitous computing, computers not only disappear from our perception, but also from our experience. When these new and almost invisible technological devices are tied together, for instance in the Internet of Things, the information resulting from that connection will be more than the sum of its parts. The Internet is the place where subjects are connected and where they exchange and share information. With the development of the ‘Internet of things’, the Internet will also connect objects and enable them to exchange and share information. In this Internet of the future, subjects and objects are more and more connected in random coalitions and networks on the basis of information. These new connections and their seamless exchanging and sharing of information will challenge traditional organizational structures. The information produced in networks will be used for changes to our existing reality and will help create a new reality. Will this development of subjects and objects connected in networks raise new questions and challenges for science and for the development of knowledge within a changing reality?

Can human-like Bots control collective mood: agent-based simulations of online chats

International Nuclear Information System (INIS)

Tadić, Bosiljka; Šuvakov, Milovan

2013-01-01

Using an agent-based modeling approach, in this paper, we study self-organized dynamics of interacting agents in the presence of chat Bots. Different Bots with tunable ‘human-like’ attributes, which exchange emotional messages with agents, are considered, and the collective emotional behavior of agents is quantitatively analyzed. In particular, using detrended fractal analysis we determine persistent fluctuations and temporal correlations in time series of agent activity and statistics of avalanches carrying emotional messages of agents when Bots favoring positive/negative affects are active. We determine the impact of Bots and identify parameters that can modulate that impact. Our analysis suggests that, by these measures, the emotional Bots induce collective emotion among interacting agents by suitably altering the fractal characteristics of the underlying stochastic process. Positive emotion Bots are slightly more effective than negative emotion Bots. Moreover, Bots which periodically alternate between positive and negative emotion can enhance fluctuations in the system, leading to avalanches of agent messages that are reminiscent of self-organized critical states.

Full Text Available Text-based conferencing can be both asynchronous (i.e., participants log into the conference at separate times, and synchronous (i.e., interaction takes place in real time. It is thus subject to the same wide variation as the online audio- and video-conferencing methods (see the earlier Reports in this series. Synchronous text-based approaches (e.g., online chat groups and instant messaging systems are highly popular among online users generally owing to their ability to bring together special-interest groups from around the world without cost. In distance education (DE, however, synchronous chat methods are less widely used, owing in part to the problems of arranging for working adults in different time zones to join a discussion group simultaneously. Instant text messaging is more popular among DE users in view of the choice it provides between responding to a message immediately (synchronous communication or after a delay (asynchronous. The different synchronous and asynchronous approaches are likely to become more widely used in parallel with one another, as they are integrated in individual product packages.

Oncology information on the Internet.

Science.gov (United States)

Goto, Yasushi; Nagase, Takahide

2012-05-01

Owing to new developments in Internet technologies, the amount of available oncology information is growing. Both patients and caregivers are increasingly using the Internet to obtain medical information. However, while it is easy to provide information, ensuring its quality is always a concern. Thus, many instruments for evaluating the quality of health information have been created, each with its own advantages and disadvantages. The increasing importance of online search engines such as Google warrants the examination of the correlation between their rankings and medical quality. The Internet also mediates the exchange of information from one individual to another. Mailing lists of advocate groups and social networking sites help spread information to patients and caregivers. While text messages are still the main medium of communication, audio and video messages are also increasing rapidly, accelerating the communication on the Internet. Future health information developments on the Internet include merging patients' personal information on the Internet with their traditional health records and facilitating the interaction among patients, caregivers and health-care providers. Through these developments, the Internet is expected to strengthen the mutually beneficial relationships among all stakeholders in the field of medicine.

Immunity status of adults and children against poliomyelitis virus type 1 strains CHAT and Sabin (LSc-2ab in Germany

Directory of Open Access Journals (Sweden)

Diedrich Sabine

2010-12-01

Full Text Available Abstract Background In October 2007, the working group CEN/TC 216 of the European Committee for standardisation suggested that the Sabin oral poliovirus vaccine type 1 strain (LSc-2ab presently used for virucidal tests should be replaced by another attenuated vaccine poliovirus type 1 strain, CHAT. Both strains were historically used as oral vaccines, but the Sabin type 1 strain was acknowledged to be more attenuated. In Germany, vaccination against poliomyelitis was introduced in 1962 using the oral polio vaccine (OPV containing Sabin strain LSc-2ab. The vaccination schedule was changed from OPV to an inactivated polio vaccine (IPV containing wild polio virus type 1 strain Mahoney in 1998. In the present study, we assessed potential differences in neutralising antibody titres to Sabin and CHAT in persons with a history of either OPV, IPV, or OPV with IPV booster. Methods Neutralisation poliovirus antibodies against CHAT and Sabin 1 were measured in sera of 41 adults vaccinated with OPV. Additionally, sera from 28 children less than 10 years of age and immunised with IPV only were analysed. The neutralisation assay against poliovirus was performed according to WHO guidelines. Results The neutralisation activity against CHAT in adults with OPV vaccination history was significantly lower than against Sabin poliovirus type 1 strains (Wilcoxon signed-rank test P Conclusion The lack of neutralising antibodies against the CHAT strain in persons vaccinated with OPV might be associated with an increased risk of reinfection with the CHAT polio virus type 1, and this implies a putative risk of transmission of the virus to polio-free communities. We strongly suggest that laboratory workers who were immunised with OPV receive a booster vaccination with IPV before handling CHAT in the laboratory.

The Internet is of great importance in today's health sector, as most Internet users utilize online functions for health related purposes. Concerning the mental health care sector, little data exist about the Internet use of psychiatric patients. It is the scope of this current study to analyze the quantity and pattern of Internet usage among mental health patients. Patients from all services of the Department of Psychiatry at a university hospital were surveyed by completing a 29-item questionnaire. The data analysis included evaluation of frequencies, as well as group comparisons. 337 patients participated in the survey, of whom 79.5% were Internet users. Social media was utilized by less than half of the users: social networks (47.8%), forums (19.4%), chats (18.7%), blogs (12.3%). 70.9% used the Internet for mental health related reasons. The contents accessed by the patients included: information on mental disorders (57.8%), information on medication (43.7%), search for mental health services (38.8%), platforms with other patients (19.8%) and platforms with mental health professionals (17.2%). Differences in the pattern of use between users with low, medium and high frequency of Internet use were statistically significant for all entities of social media (p mental health services (p = 0.017) and usage of platforms with mental health professionals (p = 0. 048). The analysis of differences in Internet use depending on the participants' type of mental disorder revealed no statistically significant differences, with one exception. Regarding the Internet's role in mental health care, the participants showed differing opinions: 36.2% believe that the Internet has or may have helped them in coping with their mental disorder, while 38.4% stated the contrary. Most psychiatric patients are Internet users. Mental health related Internet use is common among patients, mainly for information seeking. The use of social media is generally less frequent.

BACKGROUND Alzheimer disease (AD) is a chronic neurodegenerative disease that is one of the most prevalent health problems among seniors. The cause of AD has not yet been elucidated, but many risk factors have been identified that might contribute to the pathogenesis and prognosis of AD. We conducted a meta-analysis of studies involving CHAT, TFAM, and VR22 polymorphisms and AD susceptibility to further understand the pathogenesis of AD. MATERIAL AND METHODS PubMed/Medline, Embase, Web of Science, the Cochrane Library, and Google Scholar were searched for relevant articles. Rs1880676, rs2177369, rs3810950, and rs868750 of CHAT; rs1937 and rs2306604 of TFAM; and rs10997691 and rs7070570 of VR22 are studied in this meta-analysis. RESULTS A total of 51 case-control studies with 16 446 cases and 16 057 controls were enrolled. For CHAT, rs2177369 (G>A) in whites and rs3810950 (G>A) in Asians were found to be associated with AD susceptibility. No association was detected between rs1880676 and rs868750 and AD risk. For TFAM and VR22, no significant association was detected in studied single-nucleotide polymorphisms (SNPs). CONCLUSIONS Rs2177369 and rs3810950 of CHAT are associated with AD susceptibility, but rs1880676 and rs868750 are not. Rs1937 and rs2306604 of TFAM, and rs10997691 and rs7070570 of VR22 are not significantly associated with AD risk.

Contextual Hub Analysis Tool (CHAT): A Cytoscape app for identifying contextually relevant hubs in biological networks.

2016-01-01

Highly connected nodes (hubs) in biological networks are topologically important to the structure of the network and have also been shown to be preferentially associated with a range of phenotypes of interest. The relative importance of a hub node, however, can change depending on the biological context. Here, we report a Cytoscape app, the Contextual Hub Analysis Tool (CHAT), which enables users to easily construct and visualize a network of interactions from a gene or protein list of interest, integrate contextual information, such as gene expression or mass spectrometry data, and identify hub nodes that are more highly connected to contextual nodes (e.g. genes or proteins that are differentially expressed) than expected by chance. In a case study, we use CHAT to construct a network of genes that are differentially expressed in Dengue fever, a viral infection. CHAT was used to identify and compare contextual and degree-based hubs in this network. The top 20 degree-based hubs were enriched in pathways related to the cell cycle and cancer, which is likely due to the fact that proteins involved in these processes tend to be highly connected in general. In comparison, the top 20 contextual hubs were enriched in pathways commonly observed in a viral infection including pathways related to the immune response to viral infection. This analysis shows that such contextual hubs are considerably more biologically relevant than degree-based hubs and that analyses which rely on the identification of hubs solely based on their connectivity may be biased towards nodes that are highly connected in general rather than in the specific context of interest. CHAT is available for Cytoscape 3.0+ and can be installed via the Cytoscape App Store ( http://apps.cytoscape.org/apps/chat).

Internet Safety and Malaysian Students: A Study of Female Undergraduates and Their Net Pals

Directory of Open Access Journals (Sweden)

Cheong Lee Mei, Dianne

2007-12-01

Full Text Available Malaysian female undergraduates are perceived as able to rationally evaluate and estimate risks towards Net pals. Friendship is secured online while deception and fraud are revealed offline. Based on what they have been informed, the female undergraduates may know their Net pals’ likes and dislikes but the invisible cyber veil does not allow them to penetrate the illusion and accurately evaluate a person’s character and personality. This study examined how Malaysian female undergraduates use the Internet, perceive risks in meeting Net pals and the safety awareness surrounding cyber friendship. Responses of 118 female undergraduates (43% from UiTM, 30% from UM, 27% from MMU to a survey indicated that Net pals were befriended through chat rooms and websites. More than half of the female undergraduates would have a face-to-face meeting with their Net pals without the knowledge of relevant parties and have done at least one potentially unsafe behaviour. If the extent and level of Internet safety awareness is known, the problem of Internet deception that might lead to potential social problems such as rape and sexual abuse can be effectively addressed.

The Influence of Setting on Findings Produced in Qualitative Health Research: A Comparison between Face-to-Face and Online Discussion Groups about HIV/AIDS

Directory of Open Access Journals (Sweden)

Guendalina Graffigna

2006-09-01

Full Text Available The authors focus their analysis in this article on online focus groups (FGs, in an attempt to describe how the setting shapes the conversational features of the discussion and influences data construction. Starting from a review of current dominant viewpoints, they compare face-to-face discussion groups with different formats of online FGs about AIDS, from a discourse analysis perspective. They conducted 2 face-to-face FGs, 2 chats, 2 forums, and 2 forums+plus+chat involving 64 participants aged 18 to 25 and living in Italy. Their findings seem not only to confirm the hypothesis of a general difference between a face-to-face discussion setting and an Internet-mediated one but also reveal differences among the forms of online FG, in terms of both the thematic articulation of discourse and the conversational and relational characteristics of group exchange, suggesting that exchanges on HIV/AIDS are characterized by the setting. This characterization seems to be important for situating the choice of tool, according to research objectives, and for better defining the technical aspects of the research project.

The rapid and dramatic incursion of the Internet and social networks in everyday life has revolutionised the methods of exchanging data. Web 2.0 represents the evolution of the Internet as we know it. Internet users are no longer passive receivers, and actively participate in the delivery of information. Medical education cannot evade this process. Increasingly, students are using tablets and smartphones to instantly retrieve medical information on the web or are exchanging materials on their Facebook pages. Medical educators cannot ignore this continuing revolution, and therefore the traditional academic schedules and didactic schemes should be questioned. Analysing opinions collected from medical students regarding old and new teaching methods and tools has become mandatory, with a view towards renovating the process of medical education. A cross-sectional online survey was created with Google® docs and administrated to all students of our medical school. Students were asked to express their opinion on their favourite teaching methods, learning tools, Internet websites and Internet delivery devices. Data analysis was performed using spss. The online survey was completed by 368 students. Although textbooks remain a cornerstone for training, students also identified Internet websites, multimedia non-online material, such as the Encyclopaedia on CD-ROM, and other non-online computer resources as being useful. The Internet represented an important aid to support students' learning needs, but textbooks are still their resource of choice. Among the websites noted, Google and Wikipedia significantly surpassed the peer-reviewed medical databases, and access to the Internet was primarily through personal computers in preference to other Internet access devices, such as mobile phones and tablet computers. Increasingly, students are using tablets and smartphones to instantly retrieve medical information. © 2014 John Wiley & Sons Ltd.

Use and exchange value in mathematics education: Contemporary CHAT meets Bourdieu's sociology

OpenAIRE

Williams, Julian

2012-01-01

Empirical work has shown how mathematics education exhibits certain tensions between its value as being practically useful to production and consumption on the one hand and in offering access to scarce resources on the other hand. These tensions can be ultimately traced to the contradictions in the way mathematical knowledge enhances the use value and exchange value of labour power, respectively. To understand this as a social psychological phenomenon, I look to two well-known theoretical per...

The aim of this paper is to make a descriptive analysis of Problematic Internet Use in college students, evaluating the possible association with health problems and addictive behaviors, as well as gender differences in user types. A total of 2,780 students participated in the study between 2011 and 2014, 29% of them being males (age 20.8 ± 5.1 years) and 71% females (age 20.3 ± 4.4 years). The prevalence of Problematic Internet Use (PIU) assessed by the Internet Addiction Test was 6.08%. Being under 21 years of age and studying for degrees in subjects other than the health sciences were associated factors with a higher frequency of this problem, no differences by gender or type of address were found. The results show a significant association with some health problems (migraines, back pain, excess weight or obesity, insufficient rest), psychological aspects (risk of eating disorders, risk of mental disorder, depression), family problems and discrimination; with no associations with substance use (alcohol, cannabis or tobacco) being found. Concerning the time of Internet use, weekly hours were significantly higher in women than in men, both the total time as for leisure. The analysis of the profile use in problematic users revealed that males are related to aspects of entertainment such as games or shopping online and females are related to aspects of socialization, such as chats and social networks.

'Nice people doing shady things': Drugs and the morality of exchange in the darknet cryptomarkets.

Science.gov (United States)

Masson, Kimberley; Bancroft, Angus

2018-06-02

An ethnographic analysis of drug-centred cryptomarket community and exchange, this article explores the embedded values around drug distribution and consumption within this setting. Drawing on our interviews with cryptomarket users, we analyze the ways in which users claim the cryptomarket as a space of morality, empathy, trust, reciprocity, knowledge transfer, harm reduction and self-limitation. The anthropological concept of the morality of exchange is central to our theoretical approach. Between December 2014 and July 2017, nine interviews were undertaken with users of drug cryptomarkets. These were conducted in person, using Skype video calling, and using the encrypted 'self-erasing' chat app Wickr. The researchers also used overt non-participant observation (NPO) within the cryptomarket forum. This two-pronged approach - interviews and spending time within the community via NPO - enabled a thick description style of ethnographic analysis. Our research reveals online drug markets less as perfect markets (working to rules of supply and demand) and more as constructive communities of interest that perform and negotiate drug use and supply. We found that participation within these interest communities had practical impact such as changing the type of drug that users consume and the ways in which they participate in street drug supply. Significantly, these values and actions mediate the interface between online action and 'meatspace' (the offline world) and reinforce that the motivations and processes of internet activity are just as 'real' as offline action. We redefine the illicit drug focused cryptomarket as a place of exchange, mediation and reciprocity. Real-time knowledge transfer with the aim of harm reduction is one example of the impact of cryptomarket interaction. We caution that this is not a space of kinship and affinity: it is not without its scams, hackers and threats. It is, however, much more than a 'drug marketplace' and to understand how users

In this paper, we empirically study the evolution of large scale Internet topology at the autonomous system (AS) level. The network size grows in an exponential form, obeying the famous Moore's law. We theoretically predict that the size of the AS-level Internet will double every 5.32 years. We apply the k-core decomposition method on the real Internet, and find that the size of a k-core with larger k is nearly stable over time. In addition, the maximal coreness is very stable after 2003. In contrast to the predictions of most previous models, the maximal degree of the Internet is also relatively stable versus time. We use the edge-exchange operation to obtain the randomized networks with the same degree sequence. A systematical comparison is drawn, indicating that the real Internet is more loosely connected, and both the full Internet and the nucleus are more disassortative than their randomized versions.

Tutorial chat: a case study of synchronous communication in a learning environment

Malcolm Rutter

2006-12-01

Full Text Available This case study describes the use of a web-based synchronous chat application, run during computing tutorials. The chat room was moderated by a paid demonstrator, who assisted and encouraged students whenever possible. Most of the discussion was banter, which acted as a lubricant for relevant factual communication. Students were permitted a degree of anonymity, but nevertheless learned to treat the facility in a useful manner. The application and its mode of employment were found to be both motivating and supportive. Use was evaluated by questionnaire and an analysis of student input. As a result of the experience, it is suggested that abuse will certainly occur and may be minimised by technical improvements, but never eliminated. The Rogerian approach adopted was found to have transferred emphasis from teaching a topic to the learning of generic skills.

WeChat is a promising tool for capturing electronic data; however, no research has examined its use. This study evaluates the reliability and feasibility of WeChat for administering the Pelvic Floor Impact Questionnaire Short Form 7 questionnaire to women with pelvic floor disorders. Sixty-eight pelvic floor rehabilitation women were recruited between June and December 2015 and crossover randomized to two groups. All participants completed two questionnaire formats. One group completed the paper version followed by the WeChat version; the other group completed the questionnaires in reverse order. Two weeks later, each group completed the two versions in reverse order. The WeChat version's reliability was assessed using intraclass correlation coefficients and test-retest reliability. Forty-two women (61.8%) preferred the WeChat to the paper format, eight (11.8%) preferred the paper format, and 18 (26.5%) had no preference. The younger women preferred WeChat. Completion time was 116.5 (61.3) seconds for the WeChat version and 133.4 (107.0) seconds for the paper version, with no significant difference (P = 0.145). Age and education did not impact completion time (P > 0.05). Consistency between the WeChat and paper versions was excellent. The intraclass correlation coefficients of the Pelvic Floor Impact Questionnaire Short Form 7 and the three subscales ranged from 0.915 to 0.980. The Bland-Altman analysis and linear regression results also showed high consistency. The test-retest study had a Pearson's correlation coefficient of 0.908, demonstrating a strong correlation. WeChat-based questionnaires were well accepted by women with pelvic floor disorders and had good data quality and reliability.

The current Internet success has already changed our social and economic world and is still continuing to revolutionize the information exchange. The exponential increase of amount and types of data that is currently exchanged on the Internet represents significant challenge for the design of future architectures and solutions. This paper reviews the current status and trends in the design of solutions and research activities in the future Internet from point of view of managing the growth of bandwidth requirements and complexity of the multimedia that is being created and shared. Outlines the challenges that are present before the video coding and approaches to the design of standardized media formats and protocols while considering the expected convergence of multimedia formats and exchange interfaces. The rapid growth of connected mobile devices adds to the current and the future challenges in combination with the expected, in near future, arrival of multitude of connected devices. The new Internet technologies connecting the Internet of Things with wireless visual sensor networks and 3D virtual worlds requires conceptually new approaches of media content handling from acquisition to presentation in the 3D Media Internet. Accounting for the entire transmission system properties and enabling adaptation in real-time to context and content throughout the media proceeding path will be paramount in enabling the new media architectures as well as the new applications and services. The common video coding formats will need to be conceptually redesigned to allow for the implementation of the necessary 3D Media Internet features.

The article explores the different types of therapeutic relationship that can evolve both on- and offline, thanks to the use of tools, such as software and applications, which enable therapists and patients contact outside of the traditional setting. Given the premise that it is practically impossible today to maintain a relationship without the use of internet and telephones, it becomes necessary to question the ways in which the online space can become a useful extension of the therapeutic setting. The authors, starting from a consideration regarding the specificity of the online therapeutic relationship, analyze the best ways to use text and email messaging with patients. Furthermore, specific interactions via group chats are presented, for example, to coordinate a therapeutic team involving several professionals. Further, video chat settings are discussed through a clinical case presentation. Lastly, the therapist's management of social networks is debated, underscoring the importance for the therapists that his or her online identity be consistent with the offline image which patients are introduced to in the traditional setting of the therapy room.

Through this research can be drawn the conclusion that NoSQL technology implementation, MongoDB, give special advantages like lighter data storage and faster data access.

Chaotic Traversal (CHAT): Very Large Graphs Traversal Using Chaotic Dynamics

Changaival, Boonyarit; Rosalie, Martin; Danoy, Grégoire; Lavangnananda, Kittichai; Bouvry, Pascal

2017-12-01

Graph Traversal algorithms can find their applications in various fields such as routing problems, natural language processing or even database querying. The exploration can be considered as a first stepping stone into knowledge extraction from the graph which is now a popular topic. Classical solutions such as Breadth First Search (BFS) and Depth First Search (DFS) require huge amounts of memory for exploring very large graphs. In this research, we present a novel memoryless graph traversal algorithm, Chaotic Traversal (CHAT) which integrates chaotic dynamics to traverse large unknown graphs via the Lozi map and the Rössler system. To compare various dynamics effects on our algorithm, we present an original way to perform the exploration of a parameter space using a bifurcation diagram with respect to the topological structure of attractors. The resulting algorithm is an efficient and nonresource demanding algorithm, and is therefore very suitable for partial traversal of very large and/or unknown environment graphs. CHAT performance using Lozi map is proven superior than the, commonly known, Random Walk, in terms of number of nodes visited (coverage percentage) and computation time where the environment is unknown and memory usage is restricted.

Ostracism via virtual chat room-Effects on basic needs, anger and pain.

Directory of Open Access Journals (Sweden)

Ana Paula Gonçalves Donate

Full Text Available Ostracism is characterized by a social pain provoked by being excluded and ignored. In order to address the effects of social ostracism in virtual non-physical interactions, we developed a more realistic paradigm as an alternative to Cyberball and assessed its effects on participant's expression of basic social needs, emotional experience and painful feeling. The chat room consisted of controlled social dialogue interactions between participants and two other (confederate chat room partners. Exclusion was manipulated by varying the number of messages a participant received (15% and 33% in exclusion and inclusion, respectively. Analysis of participant (N = 54 responses revealed that exclusion induced a lower experience of basic-need states and greater anger, compared with included participants. In addition, excluded participants reported higher levels of two specific self-pain feelings, namely tortured and hurt. Our findings suggest that this procedure is effective in inducing social ostracism in a realistic and yet highly controlled experimental procedure.

Full Text Available Background: Autism Spectrum Disorder (ASD is a developmental disorder characterized by impaired reciprocal social interaction and communication, and by a restricted, repetitive or stereotyped behavior. Early detection of autism is recommended on all toddlers from the ages of 9 months because of increasing in prevalence. The Modified Checklist for Autism (M-CHAT in Toddlers, a Revised with Follow-Up (M-CHAT-R/F is a 2-stage parent-report screening tool to assess a risk for ASD and it demonstrates an improvement compared to the original M-CHAT. It is translated to Indonesian language by Soetjiningsih and colleagues, and it needs to be validated. Methods: This is a diagnostic accuracy study conducted at Sanglah Hospital, Bali, conducted from March 2015 to December 2016. We included children 18-48 months in this study. The parents of the outpatient children in the growth and development clinic of Sanglah Hospital were asked to fill out the Indonesian M-CHAT-R/F form. In the same visit, the Autism Spectrum Disorder (ASD assessment according to the DSM-5 as a gold standard was done by the researchers, without knowing the M-CHAT-R/F result. The assessment comparison based on M-CHAT-R/F and DSM-5 was analyzed to obtain the AUC intersection on ROC curve that gives the best sensitivity and specificity. Results: We found 10.71% of our outpatient was diagnosed with autism according to DSM 5, when they are 18-24 months old. The Indonesian version of M-CHAT-R/F as an ASD screening tool has 88.9% in sensitivity and 94.6% in specificity. Conclusion: Our results suggest that the Indonesian translation of the M-CHAT-R/F is an effective screening instrument for ASD, particularly when a two-step screening process is used.

Internet addiction (IA) is an upcoming and less researched entity in psychiatry, especially in low and middle income countries. This is the first such effort to study IA amongst Indian school students of class 11th and 12th and to find its correlation with socio-educational characteristics, internet use patterns and psychological variables, namely depression, anxiety and stress. Six hundred and twenty one students of six English medium schools of Ahmedabad participated, of which 552 (88.9%) who completed forms were analyzed. Young's Internet Addiction Test and 21 item Depression Anxiety and Stress Scale were used to measure IA and psychological variables respectively. Logistic regression analysis was applied to find the predictors of IA. Sixty-five (11.8%) students had IA; it was predicted by time spent online, usage of social networking sites and chat rooms, and also by presence of anxiety and stress. Age, gender and self-rated academic performance did not predict IA. There was a strong positive correlation between IA and depression, anxiety and stress. IA may be a relevant clinical construct, and needs extensive research even in developing nations. All high school students suffering from depression, anxiety and stress must be screened for IA, and vice versa. Copyright © 2013 Elsevier B.V. All rights reserved.

Inefficient transfer of personal health records among providers negatively impacts quality of health care and increases cost. This multicenter study evaluates the implementation of the first Internet-based image-sharing system that gives patients ownership and control of their imaging exams, including assessment of patient satisfaction. Patients receiving any medical imaging exams in four academic centers were eligible to have images uploaded into an online, Internet-based personal health record. Satisfaction surveys were provided during recruitment with questions on ease of use, privacy and security, and timeliness of access to images. Responses were rated on a five-point scale and compared using logistic regression and McNemar's test. A total of 2562 patients enrolled from July 2012 to August 2013. The median number of imaging exams uploaded per patient was 5. Most commonly, exams were plain X-rays (34.7%), computed tomography (25.7%), and magnetic resonance imaging (16.1%). Of 502 (19.6%) patient surveys returned, 448 indicated the method of image sharing (Internet, compact discs [CDs], both, other). Nearly all patients (96.5%) responded favorably to having direct access to images, and 78% reported viewing their medical images independently. There was no difference between Internet and CD users in satisfaction with privacy and security and timeliness of access to medical images. A greater percentage of Internet users compared to CD users reported access without difficulty (88.3% vs. 77.5%, P Internet-based image-sharing system is feasible and surpasses the use of CDs with respect to accessibility of imaging exams while generating similar satisfaction with respect to privacy.

Barr, Neil G; Randall, Glen E; Archer, Norman P; Musson, David M

2017-10-01

The use of Internet-enabled technology (information and communication technology such as smartphone applications) may enrich information exchange among providers and, consequently, improve health care delivery. The purpose of this systematic review was to gain a greater understanding of the role that Internet-enabled technology plays in enhancing communication among physicians. Studies were identified through a search in three electronic platforms: the Association for Computing Machinery Digital Library, ProQuest, and Web of Science. The search identified 5140 articles; of these, 21 met all inclusion criteria. In general, physicians were satisfied with Internet-enabled technology, but consensus was lacking regarding whether Internet-enabled technology improved efficiency or made a difference to clinical decision-making. Internet-enabled technology can play an important role in enhancing communication among physicians, but the extent of that benefit is influenced by (1) the impact of Internet-enabled technology on existing work practices, (2) the availability of adequate resources, and (3) the nature of institutional elements, such as privacy legislation.

Nowadays, social media tools such as short message service, Twitter, video, and web-based systems are more and more used in clinical follow-up, making clinical follow-up much more time- and cost-effective than ever before. However, as the most popular social media in China, little is known about the utility of smartphone WeChat application in follow-up. In this study, we aimed to investigate the feasibility and superiority of WeChat application in clinical follow-up. A total of 108 patients diagnosed with head and neck tumor were randomized to WeChat follow-up (WFU) group or telephone follow-up (TFU) group for 6-month follow-up. The follow-ups were delivered by WeChat or telephone at 2 weeks, 1, 2, 3, and 6 months to the patients after being discharged. The study measurements were time consumption for follow-up delivery, total economic cost, lost-to-follow-up rate, and overall satisfaction for the follow-up method. Time consumption in WFU group for each patient (23.36 ± 6.16 min) was significantly shorter than that in TFU group (42.89 ± 7.15 min) (P smartphone WeChat application was found to be a viable option for follow-up in discharged patients with head and neck tumors. WFU was time-effective, cost-effective, and convenient in communication. This doctor-led follow-up model has the potential to establish a good physician-patient relationship by enhancing dynamic communications and providing individual health instructions.

2018-03-22

The aim of this study was to develop a tool to support health workers' ability to identify patients' multidimensional health literacy strengths and challenges. The tool was intended to be suitable for administration in healthcare settings where health workers must identify health literacy priorities as the basis for person-centred care. Development was based on a qualitative co-design process that used the Health Literacy Questionnaire (HLQ) as a framework to generate questions. Health workers were recruited to participate in an online consultation, a workshop, and two rounds of pilot testing. Participating health workers identified and refined ten questions that target five areas of assessment: supportive professional relationships, supportive personal relationships, health information access and comprehension, current health behaviours, and health promotion barriers and support. Preliminary evidence suggests that application of the Conversational Health Literacy Assessment Tool (CHAT) can support health workers to better understand the health literacy challenges and supportive resources of their patients. As an integrated clinical process, the CHAT can supplement existing intake and assessment procedures across healthcare settings to give insight into patients' circumstances so that decisions about care can be tailored to be more appropriate and effective.

Use of lidar point cloud data to support estimation of residual trace metals stored in mine chat piles in the Old Lead Belt of southeastern, Missouri

Science.gov (United States)

Witt, Emitt C.

2016-01-01

Historic lead and zinc (Pb-Zn) mining in southeast Missouri’s ―Old Lead Belt‖ has left large chat piles dominating the landscape where prior to 1972 mining was the major industry of the region. As a result of variable beneficiation methods over the history of mining activity, these piles remain with large quantities of unrecovered Pb and Zn and to a lesser extent cadmium (Cd). Quantifying the residual content of trace metals in chat piles is problematic because of the extensive field effort that must go into collecting elevation points for volumetric analysis. This investigation demonstrates that publicly available lidar point data from the U.S. Geological Survey 3D Elevation Program (3DEP) can be used to effectively calculate chat pile volumes as a method of more accurately estimating the total residual trace metal content in these mining wastes. Five chat piles located in St. Francois County, Missouri, were quantified for residual trace metal content. Utilizing lidar point cloud data collected in 2011 and existing trace metal concentration data obtained during remedial investigations, residual content of these chat piles ranged from 9247 to 88,579 metric tons Pb, 1925 to 52,306 metric tons Zn, and 51 to 1107 metric tons Cd. Development of new beneficiation methods for recovering these constituents from chat piles would need to achieve current Federal soil screening standards. To achieve this for the five chat piles investigated, 42 to 72% of residual Pb would require mitigation to the 1200 mg/kg Federal non-playground standard, 88 to 98% of residual Zn would require mitigation to the Ecological Soil Screening level (ESSL) for plant life, and 70% to 98% of Cd would require mitigation to achieve the ESSL. Achieving these goals through an existing or future beneficiation method(s) would remediate chat to a trace metal concentration level that would support its use as a safe agricultural soil amendment.

End-to-End Privacy Protection for Facebook Mobile Chat based on AES with Multi-Layered MD5

Directory of Open Access Journals (Sweden)

Wibisono Sukmo Wardhono

2018-01-01

Full Text Available As social media environments become more interactive and amount of users grown tremendously, privacy is a matter of increasing concern. When personal data become a commodity, social media company can share users data to another party such as government. Facebook, inc is one of the social media company that frequently asked for user’s data. Although this private data request mechanism through a formal and valid legal process, it still undermine the fundamental right to information privacy. In This Case, social media users need protection against privacy violation from social media platform provider itself.  Private chat is the most favorite feature of a social media. Inside a chat room, user can share their private information contents. Cryptography is one of data protection methods that can be used to hides private communication data from unauthorized parties. In our study, we proposed a system that can encrypt chatting content based on AES and multi-layered MD5 to ensure social media users have privacy protection against social media company that use user informations as a commodity. In addition, this system can make users convenience to share their private information through social media platform.

Virtual environments (VEs) facilitate interaction and support among individuals with chronic illness, yet the characteristics of these VE interactions remain unknown. The objective of this study was to describe social interaction and support among individuals with type 2 diabetes (T2D) who interacted in a VE. Data included VE-mediated synchronous conversations and text-chat and asynchronous emails and discussion board posts from a study that facilitated interaction among individuals with T2D and diabetes educators (N=24) in 2 types of sessions: education and support. VE interactions consisted of communication techniques (how individuals interact in the VE), expressions of self-management (T2D-related topics), depth (personalization of topics), and breadth (number of topics discussed). Individuals exchanged support more often in the education (723/1170, 61.79%) than in the support (406/1170, 34.70%) sessions or outside session time (41/1170, 3.50%). Of all support exchanges, 535/1170 (45.73%) were informational, 377/1170 (32.22%) were emotional, 217/1170 (18.55%) were appraisal, and 41/1170 (3.50%) were instrumental. When comparing session types, education sessions predominately provided informational support (357/723, 49.4%), and the support sessions predominately provided emotional (159/406, 39.2%) and informational (159/406, 39.2%) support. VE-mediated interactions resemble those in face-to-face environments, as individuals in VEs engage in bidirectional exchanges with others to obtain self-management education and support. Similar to face-to-face environments, individuals in the VE revealed personal information, sought information, and exchanged support during the moderated education sessions and unstructured support sessions. With this versatility, VEs are able to contribute substantially to support for those with diabetes and, very likely, other chronic diseases. ©Allison A Lewinski, Ruth A Anderson, Allison A Vorderstrasse, Edwin B Fisher, Wei Pan, Constance

Beutel, Manfred E; Brähler, Elmar; Glaesmer, Heide; Kuss, Daria J; Wölfling, Klaus; Müller, Kai W

2011-05-01

In our study, we attempted to identify systematically the use of Internet applications in the German population in order to derive risk factors for problematic use. In a representative survey of the German population, we queried 1,401 women and 1,111 men between the ages of 14 and 94 years by specific questions and standardized questionnaires on depression, anxiety (HADS), and depersonalization (CDS-2). The majority of the German population (55%) used the Internet in their leisure time. Users were younger and had a higher socioeconomic status (education, employment, income). Leisure-time use included e-mail and information search, as well as shopping. Chatting, online communities, games and sex were domains of young, mostly male adults. Overall, 9.3% reported at least one negative consequence of Internet use, especially neglect of recreational activities and problems with family/partner, work or education, and health. Problematic use was associated with longer average daily online times, avoidance of negative emotions, preference for certain applications (gaming, gambling, online sex) and an increased rate of depersonalization. The extent of Internet use per se is not sufficient as an addiction criterion and other negative consequences; rather, specific adverse consequences need to be identified. If the Internet is used excessively to cope with negative affect states and alternative means of coping (e.g., social support, health-promoting behavior) are diminished, a vicious cycle may ensue with increasing stress and reliance on the reinforcing properties of certain online activities that may finally lead to addictive behavior.

Access to care and use of the Internet to search for health information: results from the US National Health Interview Survey.

The insurance mandate of the Affordable Care Act has increased the number of people with health coverage in the United States. There is speculation that this increase in the number of insured could make accessing health care services more difficult. Those who are unable to access care in a timely manner may use the Internet to search for information needed to answer their health questions. The aim was to determine whether difficulty accessing health care services for reasons unrelated to insurance coverage is associated with increased use of the Internet to obtain health information. Survey data from 32,139 adults in the 2011 National Health Interview Study (NHIS) were used in this study. The exposure for this analysis was reporting difficulty accessing health care services or delaying getting care for a reason unrelated to insurance status. To define this exposure, we examined 8 questions that asked whether different access problems occurred during the previous 12 months. The outcome for this analysis, health information technology (HIT) use, was captured by examining 2 questions that asked survey respondents if they used an online health chat room or searched the Internet to obtain health information in the previous 12 months. Several multinomial logistic regressions estimating the odds of using HIT for each reported access difficulty were conducted to accomplish the study objective. Of a survey population of 32,139 adults, more than 15.90% (n=5109) reported experiencing at least one access to care barrier, whereas 3.63% (1168/32,139) reported using online health chat rooms and 43.55% (13,997/32,139) reported searching the Internet for health information. Adults who reported difficulty accessing health care services for reasons unrelated to their health insurance coverage had greater odds of using the Internet to obtain health information. Those who reported delaying getting care because they could not get an appointment soon enough (OR 2.2, 95% CI 1.9-2.5), were

Burton-Jeangros, C; Hammer, R

2013-04-24

In the literature, uses of the internet by patients are interpreted either as a resource supporting their autonomy, or as a source of perturbation in the doctor-patient relationship. Analysing 50 interviews with pregnant women, this article aims at describing the different uses made during pregnancy. Some women mostly aim at sharing their experience in their use of internet. Others are looking for specialised information, by curiosity, to complement the information received in medical visits or, more rarely, as a result of a lack of information in their exchanges with professionals. Uses of internet by patients will develop in the future and it is important that professionals take into account these different forms of internet use in their practices.

Full Text Available Highly connected nodes (hubs in biological networks are topologically important to the structure of the network and have also been shown to be preferentially associated with a range of phenotypes of interest. The relative importance of a hub node, however, can change depending on the biological context. Here, we report a Cytoscape app, the Contextual Hub Analysis Tool (CHAT, which enables users to easily construct and visualize a network of interactions from a gene or protein list of interest, integrate contextual information, such as gene expression or mass spectrometry data, and identify hub nodes that are more highly connected to contextual nodes (e.g. genes or proteins that are differentially expressed than expected by chance. In a case study, we use CHAT to construct a network of genes that are differentially expressed in Dengue fever, a viral infection. CHAT was used to identify and compare contextual and degree-based hubs in this network. The top 20 degree-based hubs were enriched in pathways related to the cell cycle and cancer, which is likely due to the fact that proteins involved in these processes tend to be highly connected in general. In comparison, the top 20 contextual hubs were enriched in pathways commonly observed in a viral infection including pathways related to the immune response to viral infection. This analysis shows that such contextual hubs are considerably more biologically relevant than degree-based hubs and that analyses which rely on the identification of hubs solely based on their connectivity may be biased towards nodes that are highly connected in general rather than in the specific context of interest.   Availability: CHAT is available for Cytoscape 3.0+ and can be installed via the Cytoscape App Store (http://apps.cytoscape.org/apps/chat.

Identifying social network (SN) links within computer-mediated communication platforms without explicit relations among users poses challenges to researchers. Our research aims to extract SN links in internet chat with multiple users engaging in synchronous overlapping conversations all displayed in a single stream. We approached this problem using three methods which build on previous research. Response-time analysis builds on temporal proximity of chat messages; word context usage builds on keywords analysis and direct addressing which infers links by identifying the intended message recipient from the screen name (nickname) referenced in the message [1]. Our analysis of word usage within the chat stream also provides contexts for the extracted SN links. To test the capability of our methods, we used publicly available data from Internet Relay Chat (IRC), a real-time computer-mediated communication (CMC) tool used by millions of people around the world. The extraction performances of individual methods and their hybrids were assessed relative to a ground truth (determined a priori via manual scoring).

The value of chat reference services: A pilot study. portal: Libraries and the Academy, 16(1, 109-129. https://doi.org/10.1353/pla.2016.0013 Objective – To investigate student, instructor, and librarian perspectives of chat reference service in the context of first-year undergraduate students conducting research for an introductory composition course. Design – Focus groups, individual interviews, and surveys. Setting – A large, public university in the United States of America. Subjects – 57 library reference providers, 36 instructors of an introductory composition course, and approximately 936 undergraduate students in certain sections of the introductory composition course who were assigned a specific research project. Methods – In spring of 2014, all participants were invited via email to respond to an anonymous chat transcript of a librarian interacting with a student working on his or her research project. Study participants could participate via a brief survey or by taking part in a focus group or individual interview. The invited instructors were asked to forward the invitation to the students in their sections, and reminder emails were sent two weeks after the initial email. Main Results – Nine instructors, 24 students, and 25 library reference providers participated in the study, representing a response rate of 25%, 3% (estimated, and 44%, respectively. The authors conducted a qualitative analysis of key themes that were derived from both the focus groups or individual interviews and the survey questions. The themes were: students as novice researchers, question negotiation, open and closed questions, instruction, speed and convenience, customer service, and referrals. The theme of “students as novice researchers” is based on student comments related to their frustrations of being inexperienced researchers, as well as librarian comments on strategies for

Abstract There is an ongoing debate in the literature whether problematic Internet use (PIU) and problematic online gaming (POG) are two distinct conceptual and nosological entities or whether they are the same. The present study contributes to this question by examining the interrelationship and the overlap between PIU and POG in terms of sex, school achievement, time spent using the Internet and/or online gaming, psychological well-being, and preferred online activities. Questionnaires assessing these variables were administered to a nationally representative sample of adolescent gamers (N=2,073; Mage=16.4 years, SD=0.87; 68.4% male). Data showed that Internet use was a common activity among adolescents, while online gaming was engaged in by a considerably smaller group. Similarly, more adolescents met the criteria for PIU than for POG, and a small group of adolescents showed symptoms of both problem behaviors. The most notable difference between the two problem behaviors was in terms of sex. POG was much more strongly associated with being male. Self-esteem had low effect sizes on both behaviors, while depressive symptoms were associated with both PIU and POG, affecting PIU slightly more. In terms of preferred online activities, PIU was positively associated with online gaming, online chatting, and social networking, while POG was only associated with online gaming. Based on our findings, POG appears to be a conceptually different behavior from PIU, and therefore the data support the notion that Internet Addiction Disorder and Internet Gaming Disorder are separate nosological entities.

Illegal activities prosecutable by law in the real life can be committed on the internet alike. In the healthcare domain, we refer mainly to selling of illegal and counterfeit drugs, exchange of pedo-pornographic material and marketing of stolen medical records. These illegal activities are made easier by recent developments of the Internet that medical community must be aware of: darknet and bitcoin. The first allows anonymous surfing and the last anonymous financial transactions. After discussing which healthcare areas are affected by these technological developments of the Internet and the deriving consequences, then the Authors express their opinion on what actions can be taken to protect internet community.

Conversational elements of online chatting: speaking practice for distance language learners?

Vincenza Tudini

2003-12-01

Full Text Available A critical issue in the delivery of language courses at a distance is to provide adequate scaffolding and monitoring1 of learners to assist them in the development of their interlanguage. As well as being one of the main reasons students enroll in language courses, oral interaction is considered beneficial to interlanguage development since it provides opportunities for negotiation of meaning. In the case of campus-based students, learners' progress in speaking the target language is supported and monitored mainly in the classroom. If non campus-based or online students do not attend face-to-face classes, how do they find opportunities for oral interaction? Using a Conversational Analysis and Second Language Acquisition perspective, the author considers elements which are common to both face-to-face oral interactions and chatting via a computer, with a view to assessing the potential of synchronous text-based communication tools to support the development of the speaking skills and interlanguage of distance language learners. This is done by reviewing findings of previous studies on synchronous text-based communication tools and identifying selected characteristics of oral interaction which are present in the chat sessions of two groups of campus-based intermediate level learners of Italian. In particular, the study focuses on repairs and incorporation of target forms, variety of speech acts, particularly questions and clarification requests, and the presence of discourse markers.

The aim of this work is to indicate the lack of corporate culture and investor communication on the Serbian stock market by analyzing investor relations via the e-communication tools of some of the best Serbian companies. This study investigates investor relations on the Internet of companies listed on the Belgrade Stock Exchange (BELEX 15 and BELEX LINE. For this purpose, the websites of the 20 largest listed companies of the Republic of Serbia were screened for investor relations items. Results obtained by using a three-stage model show that most companies in Serbia are at the second stage of internet investor relations, i.e., where information available through other sources is combined to better inform investors. In the third stage companies use the full interactive possibilities of the Internet for investor relations purposes. The author also stresses that the quality of investor relations must be a part of every company’s strategic vision.

Full Text Available In this era of science and technology, computer plays an important role in community. Today, computer is so ubiq-uitous in pharmaceutical research and development. The advent of the internet has had a significant impact on the formation of an information-driven, rapid-paced society. The number of internet users reached 150 million in only five years compared to 13 years for television and 38 years for radio. Consumer expectation for access, conven-ience, and speed has made the cyberspace superhighway a medium for knowledge exchange and for e-commerce. The internet offers a wide variety of health services and products to healthcare professionals as well as to the pub-lic. Online pharmaceutical sales have reached more than nearly $50 billion. This is a dramatic increase when com-pared to the $1.9 billion in 1999. At the click of the mouse, medications can be ordered and delivered conveniently to your door. Internet has evolved into a self-organizing media, capable of multiple interactions within. A large number of consumer products including drugs are being advertised and sold over the Internet. Though the market-ing of drugs over the Internet is an inevitable outcome of the booming e-economy, it poses unique ethical, legal and quality challenges- the prime cause being the anarchic structure of the Internet. These challenges are important from the consumer, physician and regulator perspectives. This paper begins with a summary of historical considera-tions and the shifting organization of internet pharmacy. The advantages and disadvantages of internet pharmacy practice are listed. Internet pharmacy is not only affordable but also can be source of easy availability of medicine.

As the use of point-of-care sonography spreads, so too does the need for remote expert over-reading via telesonogrpahy. We sought to assess the feasibility of using familiar, widespread, and cost-effective existent technology to allow remote over-reading of sonograms in real time and to compare 4 different methods of transmission and communication for both the feasibility of transmission and image quality. Sonographic video clips were transmitted using 2 different connections (WiFi and 3G) and via 2 different videoconferencing modalities (iChat [Apple Inc, Cupertino, CA] and Skype [Skype Software Sàrl, Luxembourg]), for a total of 4 different permutations. The clips were received at a remote location and recorded and then scored by expert reviewers for image quality, resolution, and detail. Wireless transmission of sonographic clips was feasible in all cases when WiFi was used and when Skype was used over a 3G connection. Images transmitted via a WiFi connection were statistically superior to those transmitted via 3G in all parameters of quality (average P = .031), and those sent by iChat were superior to those sent by Skype but not statistically so (average P = .057). Wireless transmission of sonographic video clips using inexpensive hardware, free videoconferencing software, and domestic Internet networks is feasible with retention of image quality sufficient for interpretation. WiFi transmission results in greater image quality than transmission by a 3G network.

On average, 570 million users, 93% in China's first-tier cities, log on to WeChat every day. WeChat has become the most widely and frequently used social media in China, and has been profoundly integrated into the daily life of many Chinese people. A variety of health-related information may be found on WeChat. The objective of this study is to understand how the general public views the impact of the rapidly emerging social media on health information acquisition. A self-administered questionnaire was designed, distributed, collected, and analyzed utilizing the online survey tool Sojump. WeChat was adopted to randomly release the questionnaires using convenience sampling and collect the results after a certain amount of time. (1) A total of 1636 questionnaires (WeChat customers) were collected from 32 provinces. (2) The primary means by which respondents received health education was via the Internet (71.79%). Baidu and WeChat were the top 2 search tools utilized (90.71% and 28.30%, respectively). Only 12.41% of respondents were satisfied with their online health information search. (3) Almost all had seen (98.35%) or read (97.68%) health information; however, only 14.43% believed that WeChat health information could improve health. Nearly one-third frequently received and read health information through WeChat. WeChat was selected (63.26%) as the most expected means for obtaining health information. (4) The major concerns regarding health information through WeChat included the following: excessively homogeneous information, the lack of a guarantee of professionalism, and the presence of advertisements. (5) Finally, the general public was most interested in individualized and interactive health information by managing clinicians, they will highly benefit from using social media rather than Internet search tools. The current state of health acquisition proves worrisome. The public has a high chance to access health information via WeChat. The growing popularity of

Internet of Things (IoT) is an environment in which everywhere and every device became smart in a smart world. Internet of Things is growing vastly; it is an integrated system of uniquely identifiable communicating devices which exchange information in a connected network to provide extensive services. IoT devices have very limited memory, computational power, and power supply. Traditional operating systems (OS) have no way to meet the needs of IoT systems. In this paper, we thus analyze the challenges of IoT OS and survey applicable open source OSs.

In 2002, we found gender differences in the use of the Internet. Since then, however, the Internet has changed considerably. We therefore conducted a follow-up study in 2012. The study involved 501 students (389 females and 100 males, 12 participants unspecified gender) and we measured Internet use, Internet anxiety, and Internet identification. We found that males had a greater breadth of Internet use; they used the Internet more for games and entertainment than females. The differentiation between males and females in terms of Internet use is evident, and in some ways is even more distinct than 10 years ago. In our previous research we had found no gender differences in the use of the Internet for communication, whereas in the current study we have found that females use the Internet for communication than males and were using social network sites more than males. We also found, consistent with our previous study, that Internet identification and Internet anxiety were related to Internet use.

Frangos, Christos C; Frangos, Constantinos C; Sotiropoulos, Ioannis

2011-01-01

The aim of this paper is to investigate the relationships between Problematic Internet Use (PIU) among university students in Greece and factors such as gender, age, family condition, academic performance in the last semester of their studies, enrollment in unemployment programs, amount of Internet use per week (in general and per application), additional personal habits or dependencies (number of coffees, alcoholic drinks drunk per day, taking substances, cigarettes smoked per day), and negative psychological beliefs. Data were gathered from 2,358 university students from across Greece. The prevalence of PIU was 34.7% in our sample, and PIU was significantly associated with gender, parental family status, grade of studies during the previous semester, staying or not with parents, enrollment of the student in an unemployment program, and whether the student paid a subscription to the Internet (p pornographic sites, chat rooms, advertisement sites, Google, Yahoo!, their e-mail, ftp, games, and blogs more than non-problematic Internet users. PIU was also associated with other potential addictive personal habits of smoking, drinking alcohol or coffee, and taking drugs. Significant risk factors for PIU were being male, enrolment in unemployment programs, presence of negative beliefs, visiting pornographic sites, and playing online games. Thus PIU is prevalent among Greek university students and attention should be given to it by health officials.

2013-04-01

Netto shinju, or Internet group suicide, is a contemporary form of Japanese suicide where strangers connect on the Internet and make plans to commit suicide together. In the past decade, numerous incidents have occurred whereby young Japanese make contact on the Internet, exchange tips on suicide methods, and make plans to meet offline for group/individual suicide. A systematic qualitative content/thematic analysis of online communications posted on a popular Japanese suicide bulletin board yielded a textured, thematic understanding of this phenomenon. Themes identified reflected Shneidman's theory of suicide but with an emphasis on interpersonal concerns that are embedded in Japanese culture.

The study objectives were to evaluate the prevalence, predictors, and implications of pornographic Internet site (PIS) use among Greek adolescents. A cross-sectional study was conducted among 529 randomly selected Greek high school students. The prevalence of overall PIS use was 19.47% (n = 96). Among PIS users, 55 (57.29%) reported infrequent and 41 (42.71%) reported frequent PIS use. The predictors of infrequent PIS use included male gender (adjusted odds ratio [AOR] = 8.33; 95% confidence interval [CI] = 3.52-19.61), Internet use for sexual education (AOR = 5.26; 95% CI = 1.78-15.55), chat rooms (AOR = 2.95; 95% CI = 1.48-5.91), and purchases (AOR = 3.06; 95% CI = 1.22-7.67). The predictors of frequent PIS use were male gender (AOR = 19.61; 95% CI = 4.46-83.33), Internet use for sexual education (AOR = 7.39; 95% CI = 2.37-23.00), and less than 10 hours per week Internet use (AOR = 1.32; 95% CI = 1.10-1.59). Compared to non-PIS users, infrequent PIS users were twice as likely to have abnormal conduct problems (odds ratio [OR] = 2.74; 95% CI = 1.19-6.28); frequent PIS users were significantly more likely to have abnormal conduct problems (OR = 4.05; 95% CI = 1.57-10.46) and borderline prosocial score (OR = 4.22; 95% CI = 1.64-10.85). Thus, both infrequent and frequent PIS use are prevalent and significantly associated with social maladjustment among Greek adolescents.

2005-06-01

Full Text Available In the last ten years, the Internet and applications of it have been increasingly widely employed in modern business operations. In developed countries, the Internet is used with increasing frequency for financial reporting. And accordingly a large amount of academic research has been done into the area. Since no such research has yet been carried out in Croatia, it is a research area that is undoubtedly of interest. This investigation was carried out on a basic sample of 38 joint stock companies quoted on Croatian bourses, the shares of all of them being actively traded. The results showed that twenty of the companies made use of Internet financial reporting and eighteen had no such practice. Companies that use Internet financial reporting on the whole publish the annual reports together with the reports of their auditors. In addition, most of the companies use the PDF format for the reports that they publish. Empirical data show that the firms that use Internet financial reporting are on the whole larger and more profitable, and that their shares are more active on the bourses than the shares of companies that have no such reporting practice. Also established was a statistically significant propensity among financial institutions to use Internet reporting. Joint stock companies in the tourist sector were shown not to have a propensity for Internet financial reporting. Bearing in mind the expected growth of GDP, the growth of the capital market, with the constant growth in the number of Internet users, investment in financial reporting on the Internet could be a useful decision for joint stock companies that wish to enhance the transparency of their operations.

One of the challenges in astronomy education today is to introduce college students to the real-world practice and science of observational astronomy. Along with a good theoretical background, college students can gain an earlier, deeper understanding of the astronomy profession through direct observational and data reduction experience. However, building and managing a modest observatory is still too costly for many colleges and universities. Fortunately, advances in commercial astronomical hardware and software now allow universities to build and operate small Internet controllable observatories for a modest investment. The advantages of an Internet observatory include: 1) remote operation from a comfortable location, 2) immediate data access, 3) telescope control via a web browser, and 4) allowing both on-campus and distance education students the ability to conduct a variety of observing projects. Internet capabilities vastly expand the number of students who will be able to use the observatory, thus exposing them to astronomy as a science and as a potential career. In September 2005, the University of North Dakota (UND) Department of Space Studies began operating a small, recently renovated Internet controllable observatory. Housed within a roll-off roof 10 miles west of UND, the observatory includes a Meade 16-inch, f/10 Schmidt-Cassegrain telescope, an SBIG STL-6303e CCD with broadband filters, ACP observatory control software, focuser, and associated equipment. The observatory cost \\25,000 to build in 1996; 2005 renovation costs total \\28,000. An observatory operator prepares the telescope for use each night. Through remote operation, the roof is opened and the telescope/CCD power is turned on. The telescope is then aligned and focused before allowing students to access the observatory. Students communicate with the observatory operator via an online chat room and via telephone, if necessary, to answer questions and resolve any problems. Additional

Online Twitter journal clubs are a recent and popular innovation with the potential to increase research awareness and inform practice. The medical radiation sciences' MedRadJournalClub (MJRC) is a Twitter-based event that attracts a global group of participants at the monthly chats. An analysis of a recent MedRadJournalClub discussion evaluated the perceived benefits and limitations of medical radiation practitioners participating in an online journal club. The February 2017 chat used for analysis was based on the Journal of Medical Imaging and Radiation Sciences article by Currie et al. "Twitter Journal Club in Medical Radiation Science" that examines the educational theory behind learning and evidencing professional development through MRJC and social media. The data consisted of chat tweets which were collated using the Twitter advanced search function using the #medradjclub. An initial reviewed was performed to exclude irrelevant content. A second review was then undertaken to categorize the main theme of the tweet. The data were then subjected to thematic analysis which yielded seven different categories. The main benefits included global access due to the online nature of MRJC that has facilitated networking and collaboration. Open access to recently published research was another key benefit. The character limitation of a tweet was the most common constraint, and the dynamic nature of the twitter conversation requires multi-tasking that may be difficult. Our analysis indicated that participants use MedRadJournalClub as a source of continuing professional development with some evidence that this is directly informing clinical and educational practice.

It has been proposed that sex steroid hormones improve performance in some cognitive tasks by regulating the basal forebrain cholinergic function. However, the molecular basis of such influence still remains unknown. Current study analyzed the performance of ovariectomized rats in an autoshaping learning task after a short-term treatment with 17β-estradiol (E2: 4 and 40μg/kg) and/or progesterone (P4: 4mg/kg). These results were correlated with basal forebrain choline acetyltransferase (ChAT) and TrkA protein content. The high dose of E2 enhanced both acquisition in the autoshaping task and the content of ChAT and TrkA. P4 treatment increased ChAT and TrkA content without affecting performance of rats in the autoshaping learning task. Interestingly, the continuous and simultaneous administration of E2 plus P4 did not significantly modify behavioral and biochemical evaluated parameters. These results address the influence of both E2 and P4 on cholinergic and TrkA activity and suggest that the effects of ovarian hormones on cognitive performance involve basal forebrain cholinergic neurons.

The Internet as a Platform for Student Presentations

Science.gov (United States)

Ponomarenko, A. L.

2003-12-01

As the number of students enrolled in colleges and universities across the country increases, both class size and faculty workloads also increase, and individual students slip through wider and wider cracks. Universities are moving toward web-based technology as a way to facilitate student learning in an academic environment that is growing and changing faster than ever. Faculty web pages, hosted by the faculty's own internet provider, by the university, or by national services such as Blackboard or WebCT, are often used to bridge the gap between faculty and students. Typically, faculty web pages are used to post syllabi and announcements, to distribute course notes, and to disseminate student grades, while email replaces office hours as the preferred method of communication. While this use of the internet has already begun to transform course instruction, it represents only the simplest use of a tool that has tremendous potential, both in and out of the classroom. The internet can be used to bring back the element of personalization that is quickly lost as class size continues to grow. Much of the material covered in large introductory science classes is completely new to students, and they have trouble visualizing new concepts and placing them in context. In smaller classes, a solution might be to assign papers or projects to help students become familiar with the new concepts and new ideas. This is neither feasible nor terribly effective in large lecture courses. With the innovative use of web-based technology, student presentations as a method of learning can be reinvented, with greater impact for each student. Additional use of internet-based discussions and chats enables each student to experience many of their classmate's presentations in addition to their own. This use of the web as a media for storage and presentation of student projects is well-liked by students. They are able to work together on projects in large classes otherwise closed to such activity

The internet and the physician-patient relationship.

Sechrest, Randale C

2010-10-01

Since the emergence of the public Internet in the early 1990s, the healthcare industry has been struggling to understand how best to utilize this resource. During the last decade there has been an increase in both the interest and participation by healthcare providers in the Internet space, but many observers continue to push for more development of healthcare resources to better support the provider-patient relationship. This paper will review the historical development of the Internet, the core concepts that have driven the emergence and evolution of the Internet as a mass medium of information exchange, and how the healthcare industry can harness the Internet to improve the provider patient relationship. WHERE ARE WE NOW?: The healthcare industry continues to lag behind other industries that have been transformed by the Internet. Numerous industries including travel, real estate, retail sales, and banking have migrated both comprehensive information resources and transactions to the Internet in order to improve efficiency and customer satisfaction. That same process is occurring now in the healthcare industry. Credible and comprehensive Information resources are beginning to mature. Transactions are still in their infancy, reflecting a continued concern about privacy and security. WHERE DO WE NEED TO GO?: We need to improve information resources to educate and inform patients. Improving the availability and credibility of information resources will empower patients to make better healthcare decisions and I contend will ultimately reduce the cost of delivering care. HOW DO WE GET THERE?: Orthopaedists must first recognize the value of information resources to the patient. Effective communication with patients is a critical component of providing healthcare services. All healthcare providers should reflect on the importance of developing an effective communications strategy for their own practice and consider the benefits of participating in efforts by

Internet of Things is a ubiquitous concept where physical objects are connected over the internet and are provided with unique identifiers to enable their self-identification to other devices and the ability to continuously generate data and transmit it over a network. Hence, the security of the network, data and sensor devices is a paramount concern in the IoT network as it grows very fast in terms of exchanged data and interconnected sensor nodes. This paper analyses the authentication and access control method using in the Internet of Things presented by Jing et al. (Authentication and Access Control in the Internet of Things. In Proceedings of the 2012 32nd International Conference on Distributed Computing Systems Workshops, Macau, China, 18-21 June 2012, pp. 588-592). According to our analysis, Jing et al.'s protocol is costly in the message exchange and the security assessment is not strong enough for such a protocol. Therefore, we propose improvements to the protocol to fill the discovered weakness gaps. The protocol enhancements facilitate many services to the users such as user anonymity, mutual authentication, and secure session key establishment. Finally, the performance and security analysis show that the improved protocol possesses many advantages against popular attacks, and achieves better efficiency at low communication cost.

Problematic Internet addiction or excessive Internet use is characterized by excessive or poorly controlled preoccupations, urges, or behaviors regarding computer use and Internet access that lead to impairment or distress. Currently, there is no recognition of internet addiction within the spectrum of addictive disorders and, therefore, no corresponding diagnosis. It has, however, been proposed for inclusion in the next version of the Diagnostic and Statistical Manual of Mental Disorder (DSM). To review the literature on Internet addiction over the topics of diagnosis, phenomenology, epidemiology, and treatment. Review of published literature between 2000-2009 in Medline and PubMed using the term "internet addiction. Surveys in the United States and Europe have indicated prevalence rate between 1.5% and 8.2%, although the diagnostic criteria and assessment questionnaires used for diagnosis vary between countries. Cross-sectional studies on samples of patients report high comorbidity of Internet addiction with psychiatric disorders, especially affective disorders (including depression), anxiety disorders (generalized anxiety disorder, social anxiety disorder), and attention deficit hyperactivity disorder (ADHD). Several factors are predictive of problematic Internet use, including personality traits, parenting and familial factors, alcohol use, and social anxiety. Although Internet-addicted individuals have difficulty suppressing their excessive online behaviors in real life, little is known about the patho-physiological and cognitive mechanisms responsible for Internet addiction. Due to the lack of methodologically adequate research, it is currently impossible to recommend any evidence-based treatment of Internet addiction.

Next Generation Integrated Environment for Collaborative Work Across Internets

Energy Technology Data Exchange (ETDEWEB)

Harvey B. Newman

2009-02-24

We are now well-advanced in our development, prototyping and deployment of a high performance next generation Integrated Environment for Collaborative Work. The system, aimed at using the capability of ESnet and Internet2 for rapid data exchange, is based on the Virtual Room Videoconferencing System (VRVS) developed by Caltech. The VRVS system has been chosen by the Internet2 Digital Video (I2-DV) Initiative as a preferred foundation for the development of advanced video, audio and multimedia collaborative applications by the Internet2 community. Today, the system supports high-end, broadcast-quality interactivity, while enabling a wide variety of clients (Mbone, H.323) to participate in the same conference by running different standard protocols in different contexts with different bandwidth connection limitations, has a fully Web-integrated user interface, developers and administrative APIs, a widely scalable video network topology based on both multicast domains and unicast tunnels, and demonstrated multiplatform support. This has led to its rapidly expanding production use for national and international scientific collaborations in more than 60 countries. We are also in the process of creating a 'testbed video network' and developing the necessary middleware to support a set of new and essential requirements for rapid data exchange, and a high level of interactivity in large-scale scientific collaborations. These include a set of tunable, scalable differentiated network services adapted to each of the data streams associated with a large number of collaborative sessions, policy-based and network state-based resource scheduling, authentication, and optional encryption to maintain confidentiality of inter-personal communications. High performance testbed video networks will be established in ESnet and Internet2 to test and tune the implementation, using a few target application-sets.

2009-01-01

The provision of data and information on the Internet is growing daily. For geoscientific applications, especially using geographic information systems (GIS), changing geospacial data are often needed, and thus possibly different data sources. Geospatial data should be easily available. As an increasingly important medium for exchange of geospatial data is the internet. The problem of finding appropriate datasources on the Internet remains to the user. The Internet as a technical basis, which was designed as a tool for information exchange, has changed the practice of dealing with knowledge and information on fundamental and not previously foreseeable manner. From the many individual acts social consequences result, concerning the production and disposal of knowledge. These determine the development of different solutions significantly, which also includes the production, deployment and use of geospatial data, with all its strengths and problems. Various solutions to the provision of geospatial data are available on the Internet, the targeted searching of this geodata sources on the Internet remains a shortcoming. The options of knowledge management, among other solutions, could be a possibility to ease the compilation, storage, connection, popularization and ultimately the application of geodata sources on the Internet. Communication, as a central element of the use of knowledge management, should be used in the form of a communication platform. The present study describes the variety of deployment options of geospatial data and the problems of finding data sources on the Internet. Potential hazards of geospatial data provision (also) via the Internet as well as an option to manage, update and use them for various applications on the Internet are are pointed out. (author) [de

Full Text Available Cri-du-Chat syndrome is a chromosomal abnormality that can result in several damages including developmental delay and intellectual disability of the affected child. This case study describes the occupational therapy intervention in a child with Cri-du-chat syndrome that was followed from two to four years old, in weekly sessions, at a school hospital in the state of São Paulo. Data from medical records, family reports, and occupational therapy sessions were used for case description. The initial assessment showed that the child was hypotonic, stood up only with support, and explored objects by taking them to the mouth. Occupational Therapy assistance aimed to stimulate sensorimotor performance skills (perceptual, neuromuscleskeletal and motor processing and cognitive integration and components (attention spectrum, sequencing, and learning, through make-believe activities and participation in the activities of daily living (ADL. Moreover, it was also necessary to intervene directly in the school context and the child’s family, advising parents to avoid overprotection. Through the jointffort of the multidisciplinary team and the child’s family, it was possible to contribute to the improvement of bodily functions, allowing an increase in activities and participation, considering the child’s personal factors and environmental conditions, with consequent discharge from ambulatory attendance of occupational therapy.

Internet of Things is a ubiquitous concept where physical objects are connected over the internet and are provided with unique identifiers to enable their self-identification to other devices and the ability to continuously generate data and transmit it over a network. Hence, the security of the network, data and sensor devices is a paramount concern in the IoT network as it grows very fast in terms of exchanged data and interconnected sensor nodes. This paper analyses the authentication and access control method using in the Internet of Things presented by Jing et al (Authentication and Access Control in the Internet of Things. In Proceedings of the 2012 32nd International Conference on Distributed Computing Systems Workshops, Macau, China, 18–21 June 2012, pp. 588–592). According to our analysis, Jing et al.'s protocol is costly in the message exchange and the security assessment is not strong enough for such a protocol. Therefore, we propose improvements to the protocol to fill the discovered weakness gaps. The protocol enhancements facilitate many services to the users such as user anonymity, mutual authentication, and secure session key establishment. Finally, the performance and security analysis show that the improved protocol possesses many advantages against popular attacks, and achieves better efficiency at low communication cost.

Participants were given a battery of psychological tests to explore levels of internet addiction, mood, anxiety, depression, schizotypy, and autism traits. They were then given exposure to the internet for 15 min, and re-tested for mood and current anxiety. Internet addiction was associated with long-standing depression, impulsive nonconformity, and autism traits. High internet-users also showed a pronounced decrease in mood following internet use compared to the low internet-users. The immediate negative impact of exposure to the internet on the mood of internet addicts may contribute to increased usage by those individuals attempting to reduce their low mood by re-engaging rapidly in internet use.

Empathy and the Internet: Positive Potentials vs. Risks

Directory of Open Access Journals (Sweden)

Tatjana Milivojević

2015-09-01

Full Text Available Internet enables the exchange of information with incredible speed, allowing at the same time users to share their feelings, thoughts and opinions. This exchange that can be carried out virally spreading the interest about people and events that transcends our geographical and social horizons, represents a civilizational progress when it’s not recognized just as technological progress, but also as an increasing process of humanization of man and society. Empathy, which was once reserved for the narrowest community, can now be expanded globally. This optimistic view, however, doesn’t take under consideration that human capacity for empathy isn't limitless. Perceptual, cognitive, and emotional overload can lead to saturation and desensitization or dissociation where there is apperception of others, but without any emotional involvement. The paradox of empathy lays within its possibility of being used as a means of control and manipulation: it’s then a pure mimicry of empathy. It can serve a better acquaintance, rapprochement and understanding of other people and cultures, or, on the contrary, non-relations such as impersonation, inauthentic communication, and ultimately online harassment. Therefore, the possibility that Internet gives us to be connected to others is less important than the personal attitude that each individual has towards it and to others via the network. Internet isn't empathic by itself, but it can help one’s basic empathy, which is developing in vivid interpersonal contacts in the real world, to expand to the remote and sensory unobservable others. In this article we’ll analyze the empathic potential of social networks, as well as their features that can narrow or even shut down empathy.

Modern computer technologies facilitate communication with a young cancer patient.

The aim of this paper is to show how new technologies may help the communication process in clinical practice in a department providing supportive care to patients undergoing cancer treatment. Communication via Internet chat between the psychologist and a young man who sees chatting on the Internet as a natural and familiar mode of expression was shown to be useful. The Internet link enabled us to open a communication channel with the patient and to have a conversation that would otherwise have been impossible. Although verbal communication is the most important way to communicate among people, Internet communications are certainly an opportunity worth exploring, because they may open up new channels for cancer patients whose ability to speak is restricted. We might imagine using this approach in pediatric oncology, with adolescents and preadolescents, and with young adults like the patient discussed here. The case discussed highlights the enormous difference between the mere transfer of information and genuine communication, the latter involving an encounter with the patient.

Screening Internet forum participants for depression symptoms by assembling and enhancing multiple NLP methods.

Science.gov (United States)

Karmen, Christian; Hsiung, Robert C; Wetter, Thomas

2015-06-01

Depression is a disease that can dramatically lower quality of life. Symptoms of depression can range from temporary sadness to suicide. Embarrassment, shyness, and the stigma of depression are some of the factors preventing people from getting help for their problems. Contemporary social media technologies like Internet forums or micro-blogs give people the opportunity to talk about their feelings in a confidential anonymous environment. However, many participants in such networks may not recognize the severity of their depression and their need for professional help. Our approach is to develop a method that detects symptoms of depression in free text, such as posts in Internet forums, chat rooms and the like. This could help people appreciate the significance of their depression and realize they need to seek help. In this work Natural Language Processing methods are used to break the textual information into its grammatical units. Further analysis involves detection of depression symptoms and their frequency with the help of words known as indicators of depression and their synonyms. Finally, similar to common paper-based depression scales, e.g., the CES-D, that information is incorporated into a single depression score. In this evaluation study, our depressive mood detection system, DepreSD (Depression Symptom Detection), had an average precision of 0.84 (range 0.72-1.0 depending on the specific measure) and an average F measure of 0.79 (range 0.72-0.9).

The History of the Internet Search Engine: Navigational Media and the Traffic Commodity

Science.gov (United States)

van Couvering, E.

This chapter traces the economic development of the search engine industry over time, beginning with the earliest Web search engines and ending with the domination of the market by Google, Yahoo! and MSN. Specifically, it focuses on the ways in which search engines are similar to and different from traditional media institutions, and how the relations between traditional and Internet media have changed over time. In addition to its historical overview, a core contribution of this chapter is the analysis of the industry using a media value chain based on audiences rather than on content, and the development of traffic as the core unit of exchange. It shows that traditional media companies failed when they attempted to create vertically integrated portals in the late 1990s, based on the idea of controlling Internet content, while search engines succeeded in creating huge "virtually integrated" networks based on control of Internet traffic rather than Internet content.

The Internet of Things is one of the ideas that has become increasingly relevant in recent years. It involves connecting things to the Internet in order to retrieve information from them at any time and from anywhere. In the Internet of Things, sensor networks that exchange information wirelessly via Wi-Fi, Bluetooth, Zigbee or RF are common. In this sense, our paper presents a way in which each classroom control is accessed through Near Field Communication (NFC) and the information is shared via radio frequency. These data are published on the Web and could easily be used for building applications from the data collected. As a result, our application collects information from the classroom to create a control classroom tool that displays access to and the status of all the classrooms graphically and also connects this data with social networks.

The objective of the study is to investigate the impact of receiving daily WeChat services on one's cell phone on adherence to corticosteroid nasal spray treatment in chronic rhinosinusitis (CRS) patients after functional endoscopic sinus surgery (FESS). This study was a two-arm, randomized, follow-up investigation. Patients with chronic rhinosinusitis with/without nasal polyps following bilateral FESS were randomised to receive, or to not receive, daily WeChat service on their cell phone to take corticosteroid nasal spray treatment. A prescription of budesonide aqueous nasal spray 128 µg bid was given to all the subjects. Then they returned to the clinic after 30, 60, 90 days. The primary study outcome was adherence to nasal spray treatment, whereas secondary outcomes were change in endoscopic findings and SinoNasal Outcome Test-20 (SNOT-20). On the whole, there was a significant inter-group difference in the change of adherence rate (F = 90.88, p = 0.000). The WeChat group had much higher adherence rate than the control group during the follow-up. In terms of postoperative endoscopic scores and SNOT-20, except granulation score, no significant differences were observed between the two randomization groups. WeChat services are already after a short period of observation associated with improved adherence to corticosteroid nasal spray treatment in CRS patients after FESS.

Full Text Available Digital information and communication technologies widely brought unquestionable advances in the fields of knowledge and social life. With the advent of these new technologies, meaning negotiation has become increasingly multimodal, that is, conventional methods of meaning negotiation by writing, for example, may link up with visual, oral, and gestural modes, among many others.

Full Text Available This paper discusses the perceptions of Egyptian minority groups in relation to internet information technology with which they feel empowered to protect, affirm and communicate their oppressed existence, on local and global dimensions. The research employs qualitative methods and interpretive analysis, to focus on the use of Internet information technology tools by Egyptian minority groups, in particular, their online platforms and chat rooms, and the related issues associated with these practices and usages. The paper argues that cyberspace is used by specific minority groups in Egypt as a "gateway to freedom" in which it constitutes an ally to establish newly founded cyber identities that aide them to exercise their basic human rights of freedom of thought, speech and expression. The paper thus examines cyberspace a medium or tool for the carrying out of information exchange without the traditional fear of politics and power that is deeply engraved in the roots of the Egyptian culture. In this way, these minority groups are analysed as the newly conceived human information systems (HIS residing on Internet information technology and infrastructure. The paper proposes an adaptive and culturally sensitive model of human information systems as well as human information systems development life cycle (HISDLC to aid in establishing effective processes of information exchange and creation, hence assisting in the emancipation of conflicting parties residing in Egypt, elsewhere in the Middle East and globally.

Full Text Available Marketing aspects of the Internet can be examined through a great number of researches on marketing practices conducted via the Internet. A number of authors consider the Internet as new marketplace (marketspace, where the exchange of both traditional and new values (i.e. digital products and services takes place. The Internet supports almost all aspects of a company’s business activities and can be applied with respect to all the elements of marketing mix. The subject of this paper is the role of adoption and use of the Internet as a new communication, retail and distribution channel for young consumers. The research was conducted in January 2006 and included 869 students from nine faculties at the University of Zagreb. Students represent an important marketing segment for Internet marketing activities since they are considered to be advanced users of the Internet. The relevance of students’ Internet adoption and use is determined by the following reasons: students are consumers; senior students will soon become young employed professionals with their own income (their spending will increase rapidly; in the near future, senior students will, to some extent, be decision makers on the implementation of business activities via the Internet. Research results show that students actively use the Internet, primarily as a communication channel. The student use of the Internet for purchasing tangible products is rare but their use of services via the Internet is considerable. Students find using the Internet to be a non-complex activity. There is no significant difference in the perception of complexity of the Internet usage among respondents with different computer and English language skills or with respect to their majoring fields (Arts, Biomedicine, Biotechnology, Engineering, Humanities, Natural and Social Sciences. A perception of the complexity of product purchase and service usage via the Internet is influenced by the experience that

Malaria is the main health risk for Chinese expatriates working in Niger. Health education is a recommended intervention for prevention of malaria among non-immune travellers and expatriate workers. It is urgent to develop an effective and feasible way for these populations to obtain information about the prevention and treatment of malaria. An individually randomized, unblinded, controlled trial was used to evaluate the effectiveness of using WeChat official accounts for health education to improve malaria health literacy among Chinese expatriates in Niger. A total 1441 participants completed a baseline malaria health literacy questionnaire and were randomly assigned to an intervention or comparison group in a ratio of 1:1. From July to October 2014, 50 malaria prevention and treatment messages were sent to the intervention group; 50 health news messages were concurrently sent to the control group. Both groups completed the malaria health literacy questionnaire again 4 months after the start of the education intervention. A questionnaire addressing satisfaction with the health education programme was completed by the intervention group. Malaria morbidity data for 2013 and 2014 were also collected. At baseline, participant health literacy rates were 58.29, 62, 54, and 34% for skills, knowledge, practice, and attitude, respectively. After the intervention, rates for all four aspects of malaria literacy were above 70%. There was greater change in knowledge, attitude, practice, skills, and overall health literacy among the intervention group compared with the controls, with a statistically significant difference (p WeChat health education programme with over 80% stating that they would continue to follow the programme.

Full Text Available Given the importance of the Internet as a contact tool at an intercultural and multilingual level, and considering a definition of communication spaces as places where images about the Other emerge and are negotiated, we will analyze a corpus of plurilingual interactions in chat conversations (in Romance Languages, in order to study the dynamics of the images and stereotypes in this communication situation. We will attempt to uncover barriers to intercultural communication, expose some utopias about it (like the use of a lingua franca as a solution to communication problems and discover the possibilities propelling interaction, such as an affective relationship with the languages, the speakers and the communication situation. Data discussion will allow us to demonstrate how crossed images and stereotypes of the speakers towards others, their languages and cultures emerge in the interaction, how they feed and stimulate conversation and how they trigger ‘happy’ moments of plurilingual communication.
