    To examine the impact of cessation of an internet session on skin conductance responses and anxiety of higher and lower problem internet users, in order to explore possible physiological withdrawal effects. Participants were measured in terms of their skin conductance before (15min), during (15min), and after (15min) an internet session, and completed self-report measures of state anxiety and problematic internet use. Higher, but not lower, problem users showed increased skin conductance after internet use was stopped, relative to before their internet session. Higher problem users' GSR scores increased, as the time from internet cessation became longer. Higher problem users also showed increased levels of anxiety, following their internet session, which correlated with their skin conductance scores. These results suggest that, following termination of an internet session, withdrawal-like effects are seen, both psychologically and physiologically. Copyright © 2017 Elsevier Ltd.

    Full Text Available This work was a part of a broader empirical study of Internet users with excessive and dysfunctional Internet use symptoms. The aim of this particular article was to describe user profiles of Internet addicts in Serbia. The study recruited 100 subjects in total, 50 in both the clinical and control group. The clinical group included the Internet users who asked for professional help due to the symptoms of the excessive Internet use and fulfilled the diagnostic criteria for Internet behavior disorder proposed by the American Psychology Association. The results have shown that population with Internet addiction symptoms equally included both males and females, mostly adolescent and younger population, teenagers and university students, persons with higher income and users from economically more developed areas of Serbia. The user profile of this group is characterized by frequent logging on with intervals of several hours online at one time, mainly in the evening or at night, and also intensive negative reactions to any form of Internet access deprivation. By means of factor analysis, three dimensions of pathological use have been established: mixed type with particular need for up-to-date information, social interaction addiction and need for fun-seeking, namely pursuing hobbies online (cyberpornography, online games, music, art and so on.

    While problematic Internet use is recognized to be predominant among male adolescents, a female trend is gradually becoming apparent. Our study aimed at investigating the characteristics of female Internet users and distinguishing between the online activities of problematic and regular Internet users' on school days. Data were retrieved from a cross-sectional survey of a representative sample of 3067 8th graders in the canton of Vaud, Switzerland, that completed an online questionnaire in 2012. Only females were included. Based on the Internet addiction test, the sample was divided into regular (RUs) (IAT smartphone (OR 1.79) or tablet (OR 1.84). PIUs were less likely to be physically active (OR 0.86) and more likely to present poor emotional well-being (OR 2.67) and to smoke (OR 1.88). A sizeable percentage of female adolescents are problematic Internet users. When performing a comprehensive biopsychosocial assessment, teenagers owning numerous devices to access the Internet, presenting other health-compromising behaviors or poor emotional well-being should be specifically targeted.

    Internationally, up to 15.1% of intensive Internet use among adolescents is dysfunctional. To provide a basis for early intervention and preventive measures, understanding the motives behind intensive Internet use is important. This study aims to develop a questionnaire, the Internet Motive Questionnaire for Adolescents (IMQ-A), as a theory-based measurement for identifying the underlying motives for high-risk Internet use. More precisely, the aim was to confirm the 4-factor structure (ie, social, enhancement, coping, and conformity motives) as well as its construct and concurrent validity. Another aim was to identify the motivational differences between high-risk and low-risk Internet users. A sample of 101 German adolescents (female: 52.5%, 53/101; age: mean 15.9, SD 1.3 years) was recruited. High-risk users (n=47) and low-risk users (n=54) were identified based on a screening measure for online addiction behavior in children and adolescents (Online-Suchtverhalten-Skala, OSVK-S). Here, "high-risk" Internet use means use that exceeds the level of intensive Internet use (OSVK-S sum score ≥7). The confirmatory factor analysis confirmed the IMQ-A's 4-factor structure. A reliability analysis revealed good internal consistencies of the subscales (.71 up to .86). Moreover, regression analyses confirmed that the enhancement and coping motive groups significantly predicted high-risk Internet consumption and the OSVK-S sum score. A mixed-model ANOVA confirmed that adolescents mainly access the Internet for social motives, followed by enhancement and coping motives, and that high-risk users access the Internet more frequently for coping and enhancement motives than low-risk users. Low-risk users were primarily motivated socially. The IMQ-A enables the assessment of motives related to adolescent Internet use and thus the identification of populations at risk. The questionnaire enables the development of preventive measures or early intervention programs, especially dealing

    Full Text Available The increase of smartphone ability is rapidly increasing the power consumption. Many methods have been proposed to reduce smartphone power consumption. Most of these methods use the internet connection control based on the availability of the battery power level regardless of when and where a waste of energy occurs. This paper proposes a new approach to control the internet connection based on idle time using user behavior pattern analysis. User behavior patterns are used to predict idle time duration. Internet connection control performed during idle time. During idle time internet connection periodically switched on and off by a certain time interval. This method effectively reduces a waste of energy. Control of the internet connection does not interfere the user because it is implemented on idle time.

    Internet addiction (IA) among adolescents is a serious public health problem around the world. However, there have been few studies that examine the association between IA and stressful life events and psychological symptoms among Chinese adolescent internet users. We examined the association between IA and stressful life events and psychological symptoms among a random sample of school students who were internet users (N=755) in Wuhan, China. Internet addiction, stressful life events, coping style and psychological symptoms were measured by self-rated scales. The prevalence rate of internet addiction was 6.0% among adolescent internet users. Logistic regression analyses indicated that stressors from interpersonal problem and school related problem and anxiety symptoms were significantly associated with IA after controlling for demographic characteristics. Analyses examining the coping style with the IA revealed that negative coping style may mediate the effects of stressful life events to increase the risk of IA. However, no significant interaction of stressful life events and psychological symptoms was found. These findings of the current study indicate a high prevalence of internet addiction among Chinese adolescent internet users and highlight the importance of stressors from interpersonal problem and school related problem as a risk factor for IA which mainly mediated through negative coping style.

    NASA's Earth Observing System Data and Information System (EOSDIS) has been a central component of the NASA Earth observation program since the 1990's. The data collected by NASA's remote sensing instruments, airborne platforms and field campaigns represent a significant public investment in Earth science research. EOSDIS provides free and open access of these data to a diverse end-user community worldwide. Over time the EOSDIS data user community has grown substantially in both number and in the diversity of their needs. Commensurate with this growth, there also have been substantial changes in internet-based technologies and the expectation of users demanding more sophisticated EOSDIS information products describing, highlighting and providing insight to our vast data collections. To meet these increased expectations and to more fully engage our users, EOSDIS is evolving our use of traditional forms of purely static methods of public engagement such as stand-alone text and imagery toward more immersive and interactive forms of communications. This paper highlights and elucidates the methods and forms used by EOSDIS in this emerging world of dynamic and interactive media. Lessons learned and the impacts of applying these newer methods are explained and include several examples from our current efforts. These examples include interactive, on-line webinars focusing on data discovery and access (including tool usage), informal and informative `data chats' with data experts across our EOSDIS community, and profiles of scientists, researchers, and managers actively using EOSDIS data. Our efforts also include improved conference and meeting interactions with data users through the ability to use EOSDIS data interactively during hyperwall talks and the EOSDIS Worldview data visualization and exploration client. The suite of internet-based, interactive capabilities and technologies has allowed EOSDIS to expand our user community by making the data and applications from

    The production of health information has begun to shift from commercial organizations to health care users themselves. People increasingly go online to share their own health and illness experiences and to access information others have posted, but this behavior has not been investigated at a population level in the United Kingdom. This study aims to explore access and production of user-generated health content among UK Internet users and to investigate relationships between frequency of use and other variables. We undertook an online survey of 1000 UK Internet users. Descriptive and multivariate statistical analyses were used to interpret the data. Nearly one-quarter of respondents (23.7%, 237/1000) reported accessing and sharing user-generated health content online, whereas more than 20% (22.2%, 222/1000) were unaware that it was possible to do this. Respondents could be divided into 3 groups based on frequency of use: rare users (78.7%, 612/778) who accessed and shared content less than weekly, users (13.9%, 108/778) who did so weekly, and superusers (7.5%, 58/778) who did so on a daily basis. Superusers were more likely to be male (Puser-generated online health content, only a minority of respondents reported doing so frequently. As this type of content proliferates, superusers are likely to shape the health information that others access. Further research should assess the effect of user-generated online content on health outcomes and use of health services by Internet users.

The collected data were analyzed by Pearson product-moment correlation, independent samples t-test and multiple linear regression using SPSS version 22. According to this study, 31.2% of students had internet addiction (29.9% were mildly addicted and 1.3% had severe addiction). There was a significant and inverse relationship between higher information literacy and internet addiction (R= -0.45) and (pInformation literacy" explained 20% of the variation in the outcome variable "Internet addiction". Students play a substantial role in promoting the cultural and scientific level of knowledge in society; the higher their information literacy, the lower the level of Internet addiction, and consequently the general health of society will improve. It seems that wise planning by authorities of Iran's universities to prevent internet addiction and to increase information literacy among students is needed.

    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.

    Research has shown that internet interventions can be effective for dependent users of various substances. However, less is known about the effects of these interventions on users of opioids, cocaine and amphetamines than for other substances. We aimed to investigate the effectiveness of internet interventions in decreasing the usage of these types of substances. We conducted a systematic literature search in the databases of PubMed, PsycINFO, Embase and the Cochrane Library to identify randomized controlled trials examining the effectiveness of internet interventions compared with control conditions in reducing the use of opioids, cocaine and amphetamines. No setting restrictions were applied. The risk of bias of the included studies was examined according to the Cochrane Risk of Bias assessment tool. The primary outcome was substance use reduction assessed through toxicology screening, self-report or both at post-treatment and at the follow-up assessment. Seventeen studies with 2836 adult illicit substance users were included. The risk of bias varied across the included studies. Internet interventions decreased significantly opioid [four studies, n = 606, g = 0.36; 95% confidence interval (CI) = 0.20-0.53, P internet intervention for stimulant users was small and non-significant (four studies, n = 481, P = 0.164). Overall, internet interventions decreased substance significantly use at post-treatment (17 studies, n = 2836, g = 0.31; 95% CI = 0.23-0.39, P Internet interventions demonstrate small but significant effects in decreasing substance use among various target populations at post-treatment and at the follow-up assessment. However, given the small number of available studies for certain substances, the findings should be interpreted with caution. © 2017 The Authors.

    Internet use is pervasive in many cultures. Little is known about the impact of obsessive-compulsive personality disorder (OCPD) symptoms on impulsive and compulsive psychopathologies in people who use the Internet. Adult Internet users (N = 1,323) completed an online questionnaire quantifying OCPD symptoms, likely occurrence of select mental disorders (obsessive-compulsive disorder, attention-deficit/hyperactivity disorder [ADHD], problematic Internet use, generalized anxiety disorder), and personality questionnaires of impulsivity and compulsivity. Predictors of the presence of OCPD symptoms (endorsement of at least 4 of 8 DSM-5 criteria) were identified using binary logistic regression. In regression (P OCPD symptoms were significantly associated with (in order of decreasing effect size) lower non-planning impulsivity, higher ADHD symptoms, problematic Internet use, avoidant personality disorder, female sex, generalized anxiety disorder, and some types of compulsions (checking, dressing/washing). These data suggest that OCPD symptoms, defined in terms of at least 4 of 8 DSM criteria being met, are common in Internet users. OCPD symptoms were associated with considerably higher levels of psychopathology relating to both impulsive (ADHD) and compulsive (OCD-related and problematic Internet use) disorders. These data merit replication and extension using standard in-person clinical assessments, because the current study relied on self-report over the Internet.

    Citizen Science activities concern general public engagement in scientific research activities when citizens actively contribute to science either with their intellectual effort or surrounding knowledge or with their tools and resources. The advent of technologies such as the Internet and smartphones, and the growth in their usage, has significantly increased the potential benefits from Citizen Science activities. Citizen Science observations from low-cost sensors, smartphones and Citizen Observatories, provide a novel and recent development in platforms for observing the Earth System, with the opportunity to extend the range of observational platforms available to society to spatio-temporal scales (10-100s m; 1 hr or less) highly relevant to citizen needs. The potential value of Citizen Science is high, with applications in science, education, social aspects, and policy aspects, but this potential, particularly for citizens and policymakers, remains largely untapped. Key areas where Citizen Science data start to have demonstrable benefits include GEOSS Societal Benefit Areas such as Health and Weather. Citizen Science observations have many challenges, including simulation of smaller spatial scales, noisy data, combination with traditional observational methods (satellite and in situ data), and assessment, representation and visualization of uncertainty. Within these challenges, that of the assessment and representation of uncertainty and its communication to users is fundamental, as it provides qualitative and/or quantitative information that influences the belief users will have in environmental information. This presentation will discuss the challenges in assessment and representation of uncertainty in Citizen Science observations, its communication to users, including the use of visualization, and the perception of this uncertainty information by users of Citizen Science observations.

    2015-12-01

    Across most Earth Science disciplines, research depends on the availability of samples collected above, at, and beneath Earth's surface, on the moon and in space, or generated in experiments. Many domains in the Earth Sciences have recently expressed the need for better discovery, access, and sharing of scientific samples and collections (EarthCube End-User Domain workshops, 2012 and 2013, http://earthcube.org/info/about/end-user-workshops), as has the US government (OSTP Memo, March 2014). The Internet of Samples in the Earth Sciences (iSamples) is an initiative funded as a Research Coordination Network (RCN) within the EarthCube program to address this need. iSamples aims to advance the use of innovative cyberinfrastructure to connect physical samples and sample collections across the Earth Sciences with digital data infrastructures to revolutionize their utility for science. iSamples strives to build, grow, and foster a new community of practice, in which domain scientists, curators of sample repositories and collections, computer and information scientists, software developers and technology innovators engage in and collaborate on defining, articulating, and addressing the needs and challenges of physical samples as a critical component of digital data infrastructure. A primary goal of iSamples is to deliver a community-endorsed set of best practices and standards for the registration, description, identification, and citation of physical specimens and define an actionable plan for implementation. iSamples conducted a broad community survey about sample sharing and has created 5 different working groups to address the different challenges of developing the internet of samples - from metadata schemas and unique identifiers to an architecture of a shared cyberinfrastructure for collections, to digitization of existing collections, to education, and ultimately to establishing the physical infrastructure that will ensure preservation and access of the physical

    2013-05-01

    Recent technological advances allowed the creation and use of internet-based systems where many users can collaborate gathering and sharing information for specific or general purposes: social networks, e-commerce review systems, collaborative knowledge systems, etc. Since most of the data collected in these systems is user-generated, understanding of the motivations and general behavior of users is a very important issue. Of particular interest are citizen science projects, where users without scientific training are asked for collaboration labeling and classifying information (either automatically by giving away idle computer time or manually by actually seeing data and providing information about it). Understanding behavior of users of those types of data collection systems may help increase the involvement of the users, categorize users accordingly to different parameters, facilitate their collaboration with the systems, design better user interfaces, and allow better planning and deployment of similar projects and systems. Behavior of those users could be estimated through analysis of their collaboration track: registers of which user did what and when can be easily and unobtrusively collected in several different ways, the simplest being a log of activities. In this paper we present some results on the visualization and characterization of almost 150.000 users with more than 80.000.000 collaborations with a citizen science project - Galaxy Zoo I, which asked users to classify galaxies' images. Basic visualization techniques are not applicable due to the number of users, so techniques to characterize users' behavior based on feature extraction and clustering are used.

    Little is known about how actual use of Internet health-related information is associated with health or health-related behavior. Using a nationally representative sample of 34,525 from 2012, this study examined the demographics of users of Internet health-related information (users), reports estimates of association with several health and behavioral outcomes adjusting for demographic factors, and analyzed the sample by education level, race, gender, and age. Analysis of a large nationally representative sample shows evidence that users of health-related information (users) on the Internet are younger, more educated, more likely to be insured, more likely to be female, and less likely to be African American. After adjusting for demographic differences, users are more likely to have been diagnosed with hypertension, cancer, stroke, and high cholesterol, but no evidence of current hypertension, weight-related issues, or being in fair or poor health. Users are less likely to smoke and among smokers are more likely to attempt quitting. Users are more likely to exercise, get a flu shot, pap smear, mammogram, HIV test, colon cancer screening, blood pressure check, and cholesterol check, but likely to be heavy drinkers. With few exceptions, results appear robust across gender, age groups, level of education, and ethnicity. Use is generally positively associated with prior diagnosis for several conditions and behaviors related to improved health, but I find no relationship with existing health status. The association between use of health-related Internet information and health-related behavior seems robust across levels of education, age, gender, and race.

    The Internet is an increasingly important source of health information for the general population. Both preventive health behavior and Internet use are known to be different between men and women. However, few studies have compared predictors of Internet use for health information between the sexes. To investigate the prevalence and predictors of Internet use for health information among male and female adult Internet users using data from a population-based survey in Taiwan. Respondents between the ages of 20-65 years were identified from the dataset of the 2009 Taiwan National Health Interview Survey. The outcome variable of the study, the utilization of the Internet for health information, was ascertained by asking whether the respondent had ever used the Internet to search for health information or obtain health services. Univariate and multivariate logistic regression analyses were conducted separately for men and women to evaluate factors associated with the use of Internet for health information. Of the 2741 adults aged 20-65 years who had ever used the Internet, 1766 (64.4%) of them had used it for health information or services. Multivariate logistic regression analyses showed that a higher educational level (adjusted odds ratio [AOR]=3.60, Pused Western medicine services in the past month (AOR=1.51, P=0.005) were significantly associated with health information use in male Internet users. On the other hand, age between 20-44.9 years (AOR=1.87, PInternet users. This secondary data analysis of a representative sample of Taiwan population revealed that a similar but not identical set of independent factors was associated with the use of Internet for health information between male and female Internet users.

    Full Text Available Abstract Much literature on electronic government services research could be found on adoptability issues from government and service providers point of view. Many studies have looked into adoptability factors from user perspectives and majority captured adoptability perspectives of frequent Internet users the ones who use Internet applications for more than 10 hours a week. On the contrary the perspectives of majority of Pakistani users which use Internet applications for less than 10 hours per week are never inquired. This paper tries to fill this gap by looking into electronic government adoptability perspectives and expectations of such Internet users of Pakistan which are much greater in numbers than others. An amended UTAUT model with all its moderators is used in this study and the results demonstrate that performance level ease of effort and social influence strongly effect behavioral intention of users in using electronic government services in Pakistan. The individuals behavioral intention along with presence of appropriate facilitating conditions triggers use behavior of users. The results show that only gender moderates majority of UTAUT relationships and accordingly a modified UTAUT model is presented. The paper provides certain insights for people making policies and academicians for performing further research while it stresses for service proliferation with special attention towards female population.

    Full Text Available Internet addiction (IA has become a major public health issue worldwide and is closely linked to psychiatric disorders and suicide. The present study aimed to investigate the prevalence of IA and its associated psychosocial and psychopathological determinants among internet users across different age groups.The study was a cross-sectional survey initiated by the Taiwan Suicide Prevention Center. The participants were recruited from the general public who responded to the online questionnaire. They completed a series of self-reported measures, including Chen Internet Addiction Scale-revised (CIAS-R, Five-item Brief Symptom Rating Scale (BSRS-5, Maudsley Personality Inventory (MPI, and questions about suicide and internet use habits.We enrolled 1100 respondents with a preponderance of female subjects (85.8%. Based on an optimal cutoff for CIAS-R (67/68, the prevalence rate of IA was 10.6%. People with higher scores of CIAS-R were characterized as: male, single, students, high neuroticism, life impairment due to internet use, time for internet use, online gaming, presence of psychiatric morbidity, recent suicide ideation and past suicide attempts. Multiple regression on IA showed that age, gender, neuroticism, life impairment, internet use time, and BSRS-5 score accounted for 31% of variance for CIAS-R score. Further, logistic regression showed that neuroticism, life impairment and internet use time were three main predictors for IA. Compared to those without IA, the internet addicts had higher rates of psychiatric morbidity (65.0%, suicide ideation in a week (47.0%, lifetime suicide attempts (23.1%, and suicide attempt in a year (5.1%.Neurotic personality traits, psychopathology, time for internet use and its subsequent life impairment were important predictors for IA. Individuals with IA may have higher rates of psychiatric morbidity and suicide risks. The findings provide important information for further investigation and prevention of IA.

    There has been no study that has allowed clear conclusions about the impact of suicide-related or mental health consultation-related internet use. To investigate the impacts of suicide-related or mental health consultation-related internet use. We conducted prospective observational longitudinal study with data collection at baseline screening (T0), 1 week after T0 (T1) and 7 weeks after T0 (T2). Participants with a stratified random sampling from 744,806 internet users were 20-49 years of age who employed the internet for suicide-related or mental health consultation-related reasons and internet users who did not. The main outcome was suicidal ideation. Secondary outcome measures comprised hopelessness, depression/anxiety, and loneliness. The internet users who had employed the internet for suicide-related or mental health consultation-related reasons at T0 (n = 2813), compared with those who had not (n = 2682), showed a significant increase in suicidal ideation (β = 0.38, 95%CI: 0.20-0.55) and depression/anxiety (β = 0.37, 95%CI: 0.12-0.61) from T1 to T2. Those who disclosed their own suicidal ideation and browsed for information about suicide methods on the web showed increased suicidal ideation (β = 0.55, 95%CI: 0.23-0.88; β = 0.45, 95% CI: 0.26-0.63, respectively). Although mental health consultation with an anonymous other online did not increase suicidal ideation, increased depression/anxiety was observed (β = 0.34, 95%CI: -0.03-0.71). An increased suicidal ideation was observed in the young and middle-aged who employed the internet for suicide-related or mental health consultation-related reasons. Mental health consultation via the internet was not useful, but those who did so showed worsened depression/anxiety.

    The study is the first research in Malaysia that investigates user acceptance of Internet banking service (IBS) based on Unified Theory of Acceptance and Use of Technology model (Venkatesh, Morris, Davis and Davis, 2003). Two hundred and eighty questionnaires were distributed and collected from two major cities, Kuala Lumpur and Melaka. Descriptive statistics was used to analyse the data. The results show that Malaysians have intentions of using IBS (mean rating of close to 4.00). Moreover, Malaysians recognize the benefits of IBS by giving a high mean rating (close to 4.00) to performance expectancy. However, they give relative low mean ratings (close to 3.00) on other indicators of Behavioural Intention to Use IBS such as effort expectancy, social influence, facilitating conditions and perceived credibility. Recommendations were given to promote a safe, efficient and conducive environment for user adoption of Internet banking.

    Musculoskeletal disorders are of common problems among computer (PC) users. Training of posture reform plays a significant role in the prevention of the emergence, progression and complications of these diseases. The present research was performed to study the effect of the Internet training on the posture reform of the Internet users working in two Iranian universities including Sistan and Baluchestan University and Islamic Azad University of Zahedan in 2014. This study was a quasi-experimental intervention with control group and conducted in two Iranian universities including Sistan and Baluchestan University and Islamic Azad University of Zahedan. The study was done on 160 PC users in the two groups of intervention (80 people) and control (80 people). Training PowerPoint was sent to the intervention group through the Internet and a post test was given to them after 45 days. Statistical software of SPSS 19 and statistical tests of Kolmogrov, t-test, Fisher Exact test, and correlation coefficient were used for data analysis. After the training, the mean scores of knowledge, attitude, performance and self-efficacy in the intervention group were 24.21 ± 1.34, 38.36 ± 2.89, 7.59 ± 1.16, and 45.06 ± 4.11, respectively (P Internet had a significant impact on the posture reform of the PC users. According to the findings observed, there was a significant relationship between the scores of self-efficacy-performance after training. Therefore, based on the findings of the study, it is suggested that Internet training to increase self-efficacy approach in the successive periods can be effective to reform the postures of PC users.

    The continuing technological advances in satellite communications and global networking have resulted in commercial systems that now can potentially provide capabilities for communications with space-based science platforms. This reduces the need for expensive government owned communications infrastructures to support space science missions while simultaneously making available better service to the end users. An interactive, high data rate Internet type connection through commercial space communications networks would enable authorized researchers anywhere to control space-based experiments in near real time and obtain experimental results immediately. A space based communications network architecture consisting of satellite constellations connecting orbiting space science platforms to ground users can be developed to provide this service. The unresolved technical issues presented by this scenario are the subject of research at NASA's Glenn Research Center in Cleveland, Ohio. Assessment of network architectures, identification of required new or improved technologies, and investigation of data communications protocols are being performed through testbed and satellite experiments and laboratory simulations.

    Miller, B. Paige; Duque, Ricardo; Anderson, Meredith; Ynalvez, Marcus Antonius; Palackal, Antony; Dzorgbo, Dan-Bright S.; Mbatia, Paul N.; Shrum, Wesley

    This article focuses on the nature of scientific research in less developed areas in the context of new information and communication technologies (ICTs). We examine the notion that the internet will globalize the practice of science by creating connections between researchers from geographically dispersed areas. By altering the spatial and temporal mechanisms through which professional ties are developed and maintained, internet access and use in less developed areas may change the nature of knowledge production or simply reproduce traditional practices and relationships. The diffusion of the internet to Africa, Asia, and Latin America requires us to go beyond traditional views of development and technology transfer, to contemporary neo-institutional and reagency perspectives. The potential of the internet to globalize science, however, is largely dependent on the places and institutions in which it is used, as well as the identities of its users. Reviewing data collected in Africa and Asia since 1994, we summarize findings on access to and use of the internet and its impact on scientific productivity, collaboration, networking, and gender inequity.

    Robin, Bernard

    1995-07-01

    This paper describes a suite of Macintosh graphical-user-interface (GUI) software programs that can be used in conjunction with the Internet to support geoscience education. These software programs allow science educators to access and retrieve a large body of resources from an increasing number of network sites, taking advantage of the intuitive, simple-to-use Macintosh operating system. With these tools, educators easily can locate, download, and exchange not only text files but also sound resources, video movie clips, and software application files from their desktop computers. Another major advantage of these software tools is that they are available at no cost and may be distributed freely. The following GUI software tools are described including examples of how they can be used in an educational setting: ∗ Eudora—an e-mail program ∗ NewsWatcher—a newsreader ∗ TurboGopher—a Gopher program ∗ Fetch—a software application for easy File Transfer Protocol (FTP) ∗ NCSA Mosaic—a worldwide hypertext browsing program. An explosive growth of online archives currently is underway as new electronic sites are being added continuously to the Internet. Many of these resources may be of interest to science educators who learn they can share not only ASCII text files, but also graphic image files, sound resources, QuickTime movie clips, and hypermedia projects with colleagues from locations around the world. These powerful, yet simple to learn GUI software tools are providing a revolution in how knowledge can be accessed, retrieved, and shared.

    A prototype has been developed which makes use of commercially available products in conjunction with the Java programming language to provide a secure user interface for command and control over the open Internet. This paper reports successful demonstration of: (1) Security over the Internet, including encryption and certification; (2) Integration of Java applets with a COTS command and control product; (3) Remote spacecraft commanding using the Internet. The Java-based Spacecraft Web Interface to Telemetry and Command Handling (Jswitch) ground system prototype provides these capabilities. This activity demonstrates the use and integration of current technologies to enable a spacecraft engineer or flight operator to monitor and control a spacecraft from a user interface communicating over the open Internet using standard World Wide Web (WWW) protocols and commercial off-the-shelf (COTS) products. The core command and control functions are provided by the COTS Epoch 2000 product. The standard WWW tools and browsers are used in conjunction with the Java programming technology. Security is provided with the current encryption and certification technology. This system prototype is a step in the direction of giving scientist and flight operators Web-based access to instrument, payload, and spacecraft data.

    Full Text Available Abstract Background It is recognised as good practice to use qualitative methods to elicit users' views of internet-delivered health-care interventions during their development. This paper seeks to illustrate the advantages of combining usability testing with 'theoretical modelling', i.e. analyses that relate the findings of qualitative studies during intervention development to social science theory, in order to gain deeper insights into the reasons and context for how people respond to the intervention. This paper illustrates how usability testing may be enriched by theoretical modelling by means of two qualitative studies of users' views of the delivery of information in an internet-delivered intervention to help users decide whether they needed to seek medical care for their cold or flu symptoms. Methods In Study 1, 21 participants recruited from a city in southern England were asked to 'think aloud' while viewing draft web-pages presented in paper format. In Study 2, views of our prototype website were elicited, again using think aloud methods, in a sample of 26 participants purposively sampled for diversity in education levels. Both data-sets were analysed by thematic analysis. Results Study 1 revealed that although the information provided by the draft web-pages had many of the intended empowering benefits, users often felt overwhelmed by the quantity of information. Relating these findings to theory and research on factors influencing preferences for information-seeking we hypothesised that to meet the needs of different users (especially those with lower literacy levels our website should be designed to provide only essential personalised advice, but with options to access further information. Study 2 showed that our website design did prove accessible to users with different literacy levels. However, some users seemed to want still greater control over how information was accessed.

    Full Text Available The Internet is one result of the sophistication and advancement of science and man-made technology. Various conveniences offered, one of which is social media. But unfortunately, this sophistication has an impact on the quality of education. The worst impact in the world of education that may result from social networking sites is beginning to decrease interest in student learning. This is probably because the student's learning motivation also becomes reduced because of the importance of social networking rather than the learning achievement. To minimize the negative impact, as users we must be more intelligent. Internet savvy is how an internet user can manage and utilize internet technology wisely tailored to the needs and not violate ethical and internet codes of ethics.

    In the rapidly developing use of the Internet in society, eHealth literacy-having the skills to utilize health information on the Internet-has become an important prerequisite for promoting healthy behavior. However, little is known about whether eHealth literacy is associated with health behavior in a representative sample of adult Internet users. The aim of this study was to examine the association between eHealth literacy and general health behavior (cigarette smoking, physical exercise, alcohol consumption, sleeping hours, eating breakfast, eating between meals, and balanced nutrition) among adult Internet users in Japan. The participants were recruited among registrants of a Japanese Internet research service company and asked to answer a cross-sectional Internet-based survey in 2012. The potential respondents (N=10,178) were randomly and blindly invited via email from the registrants in accordance with the set sample size and other attributes. eHealth literacy was assessed using the Japanese version of the eHealth Literacy Scale. The self-reported health behaviors investigated included never smoking cigarettes, physical exercise, alcohol consumption, sleeping hours, eating breakfast, not eating between meals, and balanced nutrition. We obtained details of sociodemographic attributes (sex, age, marital status, educational attainment, and household income level) and frequency of conducting Internet searches. To determine the association of each health behavior with eHealth literacy, we performed a logistic regression analysis; we adjusted for sociodemographic attributes and frequency of Internet searching as well as for other health behaviors that were statistically significant with respect to eHealth literacy in univariate analyses. We analyzed the data of 2115 adults (response rate: 24.04%, 2142/10,178; male: 49.74%, 1052/2115; age: mean 39.7, SD 10.9 years) who responded to the survey.

    Motivation: Recall the arguably most renowned anecdote in the history of science: the young Isaac Newton was hit on his head by a falling apple (the data!) when he sat in his garden, which inspired Newton's brilliant insight and his eventually understanding and demonstrating of gravitational force (the science!). This well-known "coupling" of "data" and "science" can be considered as the trigger for this study (as well as its title). The NASA Goddard Earth Sciences Data and Information Service Center (GES DISC) has provided massive amounts of Earth science data, information, and services to diverse research communities and the general public for decades. How much those data products from different missions or projects have been used by diverse user communities, as well as how they have been used by our various user categories (such as research scientists, applications scientists, general public, and students) for different science research or/and applications are the primary focus of this study. We have performed an integrated analysis on "data usage" vs. "science research/application" by investigating three different, yet related, groups of records, i.e., user Help Tickets (the questions and feedback from the users), user publications (info acquired especially via users' acknowledgments of using Giovanni, our powerful in-house visualization tool, in their papers), and user metrics (the collected information of data and service usage by the users) in recent years (2013-2017). For example, precipitation, hydrology, and atmospheric chemistry have been found as frequently applied science variables or/and science areas that have been exploited or/and explored by the users based on the user tickets we have analyzed so far. With regard to Giovanni, a significant minority of the users are applications users (air quality, water quality, agriculture, natural disasters, etc.) in contrast to the majority of basic research users. More users employ Giovanni as an adjunct data

    To identify users' reasons to look for physician consultation on the internet instead of visiting a physician and to explore their general characteristics, motivation, and satisfaction with internet medical consultation service 'Your Questions.' Users of a free internet medical consultation service 'Your Questions' (www.plivazdravlje.hr) were invited to participate in a web-based survey designed to explore their general characteristics (age, sex, etc), reasons for using the service, the nature of their health problem or question, and their satisfaction with the service. Respondents were divided into two groups: users who consulted an internet physician only (Group I) and users who used internet consulting before or after visiting a physician (Group II). The response rate was 38% (1036/2747), with 79% female respondents. A fifth of the respondents (21%) consulted an internet physician only (Group I). Multivariate analysis revealed that the respondents in Group I were younger (median 24 vs 28 years in Group II), more interested into questions about pregnancy (odds ratio [OR], 1.984; 95% confidence interval [CI], 1.203-3.272), more often embarrassed to talk to a physician in person (OR, 1.828; 95% CI, 1.119-2.989), and more motivated to protect their privacy (OR, 1.727; 95% CI, 1.252-2.380). They also had greater satisfaction with the service (77% vs 60%, Pinternet-based medical consultation services were younger age, need for privacy protection, avoidance of embarrassment at the physician's office, and having a question related to pregnancy. This reveals the internet medical consultation service as a useful health promotion supplement that is particularly applicable for the population of young adults.

    Full Text Available ABSTRACT The rapid development of technology today makes Internet users continues to increase. This is supported by the ease of internet users access the internet either through a PC laptop mobile phones tablets and other media. The increase in Internet users this makes the internet into a proper promotion using online advertising. With a wide reach and touch the various layers of the Internet media communities may be appropriate advice for company promotion. However an increasing number of Internet users especially in the city of Makassar is not accompanied by an increase in the number of online purchases. Based on that it is necessary to examine how the effect of online advertising on consumer buying behavior and online as well as how to control the behavior and subjective norms influence the attitudes and interests of consumers buy online. This study aims to analyze and test the effect of online advertising on consumer attitudes and purchase interest online a survey conducted on students of Internet users in the city of Makassar. The study was conducted on students of public and private universities in the city of Makassar. The method used was a quantitative analysis using the technique of purposive sampling method with a sample of 340 people. Testing this hypothesis using structural equation modeling SEM. The results showed that online advertising has an influence on consumer buying behavior and online. Dimensions interactivity of online advertising provides the highest influence on the attitudes and interests of consumers purchasing online.

    Although prescription drugs are readily available on the Internet, little is known about the prevalence of Internet use for the purchase of medications without a legitimate prescription, and the characteristics of those that obtain non-prescribed drugs through online sources. The scientific literature on this topic is limited to anecdotal reports or studies plagued by small sample sizes. Within this context, the focus of this paper is an examination of five national data sets from the U.S. with the purpose of estimating: (1) how common obtaining prescription medications from the Internet actually is, (2) who are the typical populations of "end users" of these non-prescribed medications, and (3) which drugs are being purchased without a prescription. Three of the data sets are drawn from the RADARS (Researched Abuse Diversion and Addiction-Related Surveillance) System, a comprehensive series of studies designed to collect timely and geographically specific data on the abuse and diversion of a number of prescription stimulants and opioid analgesics. The remaining data sets include the National Survey on Drug Use and Health (NSDUH) and the Monitoring the Future (MTF) survey. Our analysis yielded uniformly low rates of prescription drug acquisition from online sources across all five data systems we examined. The consistency of this finding across very diverse populations suggests that the Internet is a relatively minor source for illicit purchases of prescription medications by the individual end-users of these drugs.

    Evaluation on Internet portals is a key component of any online resource development. Understanding user information seeking behaviour and user perceived behaviour is essential to obtain the full picture of user needs, online activities and draw lessons to improve the design of Internet portals to better meet user expectations. This article discusses the evaluation of a WHO Internet portal: the Labresources website. The evaluation investigates user satisfaction with the resource, usability, demographic information about users and how well they could complete specific tasks using the website and compared this with the actual online behaviour revealing a number of discrepancies. An online questionnaire was advertised on the Labresources website during the period 25 November 2005 to 20 February 2006. As the site caters to English and French speakers, the questionnaire was made available in both languages. It consisted of two sections - the first section required the participant to complete three tasks using the website whereas the second section tested user satisfaction, information needs and appropriateness of the content. Weblogs data were compared with the questionnaire results to compare user perceived and actual online behaviour. Twenty one respondents completed the online questionnaire from a total of 18 countries. This was out of a potential 60 website users among whom the questionnaire was promoted. In general, respondents were satisfied with the website layout and navigation. 61.9% of respondents listed WHO among their top 5 and a third listed the Labresources website. The number of sessions where users browse (146) the information resources is almost three times more than the number of users who search (52) the resources. Weblogs revealed most interesting results with differences between what users reported doing when completing tasks and how easy they perceived the tasks and what they actually did.

    Web-based health information may be of particular value among the African American population due to its potential to reduce communication inequalities and empower minority groups. This study explores predictors of e-health behaviors and activities for African American Internet users. We used the 2010 Pew Internet and American Life Health Tracking Survey to examine sociodemographic and health status predictors of e-health use behaviors among African Americans. E-health use behaviors included searching for e-health information, conducting interactive health-related activities, and tracking health information online. In the African American subsample, 55% (n=395) were at least "occasional" Internet users. Our model suggests that searching for health information online was positively associated with being helped/knowing someone helped by online information (odds ratio [OR]=5.169) and negatively associated with lower income (OR=0.312). Interactive health activities were associated with having a college education (OR=3.264), being 65 years of age or older (OR=0.188), having a family member living with chronic conditions (OR=2.191), having a recent medical crisis (OR=2.863), and being helped/knowing someone helped by online information (OR=8.335). E-tracking behaviors were significantly stronger among African Americans who had health insurance (OR=3.907), were helped/knowing someone helped by online information (OR=4.931), and were social media users (OR=4.799). Findings suggest significant differences in e-health information-seeking behaviors among African American Internet users-these differences are mostly related to personal and family health concerns and experiences. Targeted online e-health resources and interventions can educate and empower a significant subset of the population.

    For the last several years the Science Directorate at Marshall Space Flight Center has carried out a diverse program of Internet-based science communication. The Directorate's Science Roundtable includes active researchers, NASA public relations, educators, and administrators. The Science@NASA award-winning family of Web sites features science, mathematics, and space news. The program includes extended stories about NASA science, a curriculum resource for teachers tied to national education standards, on-line activities for students, and webcasts of real-time events. The focus of sharing science activities in real-time has been to involve and excite students and the public about science. Events have involved meteor showers, solar eclipses, natural very low frequency radio emissions, and amateur balloon flights. In some cases, broadcasts accommodate active feedback and questions from Internet participants. Through these projects a pattern has emerged in the level of interest or popularity with the public. The pattern differentiates projects that include science from those that do not, All real-time, event-based Internet activities have captured public interest at a level not achieved through science stories or educator resource material exclusively. The worst event-based activity attracted more interest than the best written science story. One truly rewarding lesson learned through these projects is that the public recognizes the importance and excitement of being part of scientific discovery. Flying a camera to 100,000 feet altitude isn't as interesting to the public as searching for viable life-forms at these oxygen-poor altitudes. The details of these real-time, event-based projects and lessons learned will be discussed.

    2014-08-01

    In the context of Internet addiction, cybersex is considered to be an Internet application in which users are at risk for developing addictive usage behavior. Regarding males, experimental research has shown that indicators of sexual arousal and craving in response to Internet pornographic cues are related to severity of cybersex addiction in Internet pornography users (IPU). Since comparable investigations on females do not exist, the aim of this study is to investigate predictors of cybersex addiction in heterosexual women. We examined 51 female IPU and 51 female non-Internet pornography users (NIPU). Using questionnaires, we assessed the severity of cybersex addiction in general, as well as propensity for sexual excitation, general problematic sexual behavior, and severity of psychological symptoms. Additionally, an experimental paradigm, including a subjective arousal rating of 100 pornographic pictures, as well as indicators of craving, was conducted. Results indicated that IPU rated pornographic pictures as more arousing and reported greater craving due to pornographic picture presentation compared with NIPU. Moreover, craving, sexual arousal rating of pictures, sensitivity to sexual excitation, problematic sexual behavior, and severity of psychological symptoms predicted tendencies toward cybersex addiction in IPU. Being in a relationship, number of sexual contacts, satisfaction with sexual contacts, and use of interactive cybersex were not associated with cybersex addiction. These results are in line with those reported for heterosexual males in previous studies. Findings regarding the reinforcing nature of sexual arousal, the mechanisms of learning, and the role of cue reactivity and craving in the development of cybersex addiction in IPU need to be discussed.

    Full Text Available One of the most vital challenges of the Internet as a service delivery channel is providing and maintaining service quality. This study aimed to describe the profile of the respondents with regards to socio-demographic and bank-related variables; to identify the effects of internet banking among its clients in Batangas City; to determine the level of customer’s satisfaction in terms of speed and accuracy, accessibility and convenience, and security features; to determine the respondents level of loyalty; to test the relationship between effects of internet banking service and customer satisfaction and loyalty variables; and lastly, to propose effective measures on how to enhance the quality of internet banking service offered by PNB in Batangas City. The descriptive-correlation method was utilized in the conduct of the study. The respondents of the study are the top 100 or 30% of the three hundred thirty four active users of internet banking service of Philippine National Bank in Batangas City during the period of October 2012 as generated by the bank’s system. The study revealed that the respondents are generally satisfied with the speed and accuracy, accessibility and convenience, and security features of the internet banking service facility. It was also found out that only speed and accuracy showed significant relationship on the effect of internet banking. Internet banking users are still considering the speed and accuracy of the banks service to make them satisfied despite that internet banking provides lower cost delivery channel, gives customers to almost any type of banking transactions and gives breadth and depth customer service. However, customers’ level of loyalty is not affected by the effects of internet banking services. This proves that as long as the customers are being provided with an excellent service, customer loyalty/retention could still be possibly attained by the bank

    Gillette, Shana Cecile

    In communications, a new approach to the study of online interaction has been suggested by social network analysts. Garton, Haythornthwaite, and Wellman (1997) have outlined the importance of using network analysis to study how media are interconnected with other social aspects of a media user's world. As applied here, this approach to communication when combined with recent network studies from the fields of education and rural development, provides a method for looking at the role of Internet-facilitated ties in the development of resource networks in the learning communities of young women from seven rural schools across the state of Washington. Twenty-six young women (ages 14-16) from diverse cultural and ethnic backgrounds (approximately half of the participants are Hispanic or Native American, the other half are White) participated in the research. Participants were selected because they shared a common educational orientation through Rural Girls in Science, a NSF-funded program at the Northwest Center for Research on Women at the University of Washington. As part of the school-based component of the Rural Girls in Science program, all 26 participants designed and conducted year-long, community-based research projects in science. Each school in the program was provided an Internet workstation for communication and research. Through the Internet, students could conceivably maintain distant ties with mentors and research scientists whom they met at summer camp as well as seek additional information resources. Toward the conclusion of the long-term research projects, each student participant was interviewed using a participatory form of network analysis that included a combined qualitative and quantitative approach. Given the small number of participants and schools in the sample, the results from the analysis can not be generalized to a larger population. However the study of the structure and composition of networks among individuals and school groups provided

    Only few studies have examined the relationship between problematic Internet use (PIU) and cognitive and academic performance in adolescents. The aim of this study was to analyze the differences in academic and cognitive performance (perception, attention, memory, verbal fluency and abstract reasoning) between adolescents with and without PIU. A total of 575 students from different high schools of the region of Alicante participated. Students were divided into two groups: adolescents with and without PIU (PIU and NPIU, respectively). Several questionnaires were administered to assess problematic Internet use, as well as students' academic performance. Substance use (alcohol / cannabis) was also assessed as exclusion criteria. A battery of neuropsychological tests was used to assess cognitive abilities. On the one hand, PIU users group obtained poorer academic results than NPIU, in terms of lower marks and more failed subjects. On the other hand, PIU group had a better hit ratio in the perception test than NPIU group. However, PIU adolescents got higher error rates for the abstract reasoning test. This greater number of errors, plus a similar number of hits compared to the NPIU group, could indicated a higher response rate for the PIU group, which may might be associated with greater impulsivity. As occurs in other addictive and non-substance-related problems studies, these results could mean difficulties in impulse control and regulation of response inhibition circuits in PIU users group. Future research is needed to analyze in depth the results presented in this paper.

    2013-09-01

    Social networking sites such as Facebook attract millions of users by offering highly interactive social communications. Recently, a counter movement of users has formed, deciding to leave social networks by quitting their accounts (i.e., virtual identity suicide). To investigate whether Facebook quitters (n=310) differ from Facebook users (n=321), we examined privacy concerns, Internet addiction scores, and personality. We found Facebook quitters to be significantly more cautious about their privacy, having higher Internet addiction scores, and being more conscientious than Facebook users. The main self-stated reason for committing virtual identity suicide was privacy concerns (48 percent). Although the adequacy of privacy in online communication has been questioned, privacy is still an important issue in online social communications.

    While Internet users may often believe they have anonymity online, a culmination of technologies and recent research may allow an adversary to precisely locate an online user s geophysical location. In many cases, such as peer-to-peer applications, an adversary can easily use a target s IP address to quickly obtain the general geographical location of the target. Recent research has scoped this general area to a 690m (0.43 mile) radius circle. In this work, we show how an adversary can exploit Internet communication for geophysical location by embedding covert signals in communication with a target on a remote wireless local area network. We evaluated the approach in two common real-world settings: a residential neighborhood and an apartment building. In the neighborhood case, we used a single-blind trial in which an observer located a target network to within three houses in less than 40 minutes. Directional antennas may have allowed even more precise geolocation. This approach had only a 0.38% false positive rate, despite 24,000 observed unrelated packets and many unrelated networks. This low rate allowed the observer to exclude false locations and continue searching for the target. Our results enable law enforcement or copyright holders to quickly locate online Internet users without requiring time-consuming subpoenas to Internet Service Providers. Other privacy use cases include rapidly locating individuals based on their online speech or interests. We hope to raise awareness of these issues and to spur discussion on privacy and geolocating techniques.

    Internet interventions for hearing aid (HA) users have been shown to be effective in helping persons with hearing problems. As earlier research refers to objective data on these effects, little is known about how participants experience the Internet interventions subjectively. The aim of the present study was to explore participants' experiences of an Internet-based aural rehabilitation (IAR) program for HA-users, and to explore the possible subjective benefits of such a program. A qualitative exploratory design was implemented involving semi-structured telephone interviews. The interviews were transcribed and analysed using content analysis. Interviews were conducted with 20 participants (9 men and 11 women) who had completed an IAR program for HA-users. The participants were 57-81 years old and had used HAs for 2-25 years. The results are organised in three main categories: general experiences associated with participating in the program, knowledge obtained from the program and perceived impact of taking part in the program. The overall results indicate positive experiences of the IAR program, and an overreaching theme of increased self-esteem was identified. The findings provide some valuable information for developers of future IAR programs.

    Purpose: The Internet is an important information source for health practitioners providing immediate access to the most current health and medical information. Factors limiting practitioner access to the Internet have been identified and the literature shows that access to the Internet varies across and within health professions. There is therefore a need for each health profession to investigate practitioner access to the Internet. There has been, however, no identified empirical research investigating medical radiation science (MRS) practitioner access to or use of the Internet. This research sought to establish the professional use of Internet-based tools by Australian MRS practitioners and issues affecting access to the Internet within MRS workplaces. Methods: Qualitative and quantitative approaches were used in this research. These included interviews with 28 MRS practitioners from the four areas of specialisation, namely nuclear medicine, radiation therapy, radiography and sonography and a survey of MRS practitioners. In 2007 a 4-page postal survey was sent to a random sample of 1142 MRS practitioners with a response rate of 32.8%. Results: The Internet is an important information source widely used by MRS practitioners. MRS practitioners search the Internet (87%), access specific web pages (86%), use email (82%) and listservs (39.4%) to update their professional knowledge. It was evident that access to the Internet within the workplace varied within the MRS profession. Whilst the majority (96.4%) of MRS practitioners had some level of access to the Internet in their workplace, factors shown to affect practitioner access were workplace setting (p = 0.000), work environment (p = 0.000), and geographic location (p = 0.025). The majority of clinical workplaces (81%) did not provide practitioners with remote access to electronic resources available in the workplace such as e-journals and databases. Conclusions: This research provides baseline data to the MRS

    A compact and user-friendly ion irradiation system controlled remotely through the Internet was developed for the execution of collaboration experiments together with researchers at remote sites. Several hardware instruments and software programs were constructed and provided for the remote control of the system and for its connection to the Internet. Surface modification and analysis experiments with this system were remotely performed through the Internet. It was confirmed from the experiments that the present ion irradiation system was precisely controlled through the Internet and could be easily and safely used for the surface modification and analysis, that the normal communication speed of around 10 Mbps for the Internet was fast enough for the execution of such typical remote-controlled experiments, and also that an access to the system by a mobile phone was convenient and useful enough to check the condition of the system and experimental data.

    The use of the Internet for searching and sharing health information and for health care interactions may have a great potential for Renal Transplant Recipients (RTR). This study aims to determine the characteristics associated with Internet and social network use in a representative sample of RTR at the time of their inclusion in the study. Data of this cross-sectional design is retrieved from a longitudinal study conducted in five French kidney transplant centers in 2011, and included Renal Transplant Recipients aged 18 years with a functioning graft for at least 1 year. Measures include demographic characteristics (age, gender, level of education, employment status, living arrangement, having children, invalidity and monthly incomes in the household), psycho-social characteristics measured by the perceived social support questionnaire, and medical characteristics (previous dialysis treatment, duration since transplantation, graft rejection episodes, chronic graft dysfunction, health status and comorbidities: neoplasia for the current transplant, hypertension, diabetes mellitus, smoking status, BMI > 30 kg/m 2 and Charlson Comorbidity Index (CCI)). Polytomous linear regression analysis was performed to describe the Internet and social network users' profiles, using lack of Internet access as the comparison category. Among the 1416 RTR participating in the study, 20.1% had no Internet access in the household, 29.4% connected to social networks and 50.5% were not connected to social networks. Patients who connected the most to the Internet and social networks were younger, male, without children, employed, with high monthly incomes in the household, without hypertension and having felt a need for an informative or an esteem support. In our study, the majority of RTR were actively using Internet and social networks. Renal transplant units should develop flexible and Web-based sources related to transplant information, which will allow a rapid adaptation to

    Statement of the problem. Science education literature had agreed that an important goal in students' learning is the development of scientific and technological literacy. One effort that teachers have integrated into their practices for addressing this goal has been teaching within the contexts of Internet Science Projects. Greater awareness of teachers' perspectives of their best practices and their beliefs and reasons for these practices in the contexts of Internet Science Projects can improve the quality of science education programs. Methods. A series of pilot interviews was conducted during the 2000--2001 school year to develop the guiding questions for inquiring into teachers' perspectives of their best practices within the contexts of Internet Science Projects. This series of interviews resulted in the understanding of the need to select teachers with experiences with Internet Science Projects and to conduct in-depth phenomenological interviews for learning from their voices. Two teachers were purposefully selected as the participant-informants for this study, one an American elementary teacher from Walker County, Georgia, and one a Russian teacher from St. Petersburg, Russia. The study was conducted from October through December 2001. The data collected for this qualitative study consisted of a series of in-depth phenomenological interviews, classroom observations, and the collection and analysis of various artifacts including teacher journals, student products, and e-mail/bulletin board transcripts. The interview structure was based upon a modification of expanding Seidman's (1998) three interview series into multiple interviews concluded upon the determination of saturation of the topic. The series of interviews were composed of (1) life history focus; (2) the details of the experience of teaching within the contexts of Internet Science Projects; and (3) reflection on the meanings. The data analysis consisted of applying Strauss & Corbin's (1990) open

    In rapidly developing Internet-user societies, eHealth literacy has become important in promoting wellness. Although previous studies have observed that poor health literacy is associated with less knowledge and screening practice of colorectal cancer (CRC), little is known about whether eHealth literacy is associated with these variables. The present study examined associations between eHealth literacy, knowledge of CRC, and CRC screening practices. Data were analyzed for 2970 Japanese adults (men, 49.9%; mean age±SD, 39.7±10.9 years) who responded to an Internet-based cross-sectional survey. Knowledge of the definition of CRC, its risk factors and screening practice, previous experience of CRC screening, score on the Japanese version of the eHEALS (J-eHEALS), sociodemographic attributes (sex, age, marital status, educational attainment, and household income level), and frequency of Internet usage were obtained. Sociodemographic attributes and frequency of Internet usage were used as control variables in the multiple regression and logistic regression models. eHealth literacy was positively associated with CRC knowledge (β=.116, increase of 1 point in the eHEALS score signified that participants were 1.03 times (95% CI=1.01-1.05) more likely to undergo CRC screening. Internet users with high eHealth literacy are more likely to have knowledge and previous screening practice related to CRC compared to those with low eHealth literacy.

    Background and aims Internet gaming addiction appears to be related to self-concept deficits and increased angular gyrus (AG)-related identification with one's avatar. For increased social network use, a few existing studies suggest striatal-related positive social feedback as an underlying factor. However, whether an impaired self-concept and its reward-based compensation through the online presentation of an idealized version of the self are related to pathological social network use has not been investigated yet. We aimed to compare different stages of pathological Internet game and social network use to explore the neural basis of avatar and self-identification in addictive use. Methods About 19 pathological Internet gamers, 19 pathological social network users, and 19 healthy controls underwent functional magnetic resonance imaging while completing a self-retrieval paradigm, asking participants to rate the degree to which various self-concept-related characteristics described their self, ideal, and avatar. Self-concept-related characteristics were also psychometrically assessed. Results Psychometric testing indicated that pathological Internet gamers exhibited higher self-concept deficits generally, whereas pathological social network users exhibit deficits in emotion regulation only. We observed left AG hyperactivations in Internet gamers during avatar reflection and a correlation with symptom severity. Striatal hypoactivations during self-reflection (vs. ideal reflection) were observed in social network users and were correlated with symptom severity. Discussion and conclusion Internet gaming addiction appears to be linked to increased identification with one's avatar, evidenced by high left AG activations in pathological Internet gamers. Addiction to social networks seems to be characterized by emotion regulation deficits, reflected by reduced striatal activation during self-reflection compared to during ideal reflection.

    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.

    Full Text Available Inside the internet, information becomes something very important and really life. Mobility is so fast and can be downloaded, produced, and then uploaded again. The internet network is one of the most popular information sources today. Many internet users access pornographic websites because these pornographic websites supported by the development of rapid internet. The purpose of this study is to review Pornographic Law related to cyberporn.  This criminal act is called Cyberporn. Given the enormous impact that is caused by the act of pornography, especially on the internet site, the government legalized the bill against pornography into pornography law with clear criminal provisions. This research method using normative law research method, with a normative juridical approach related to pornography. In relation to this type of research is a normative legal research, then the source of legal material used is the legislation. In accordance with this type of research, the analysis used is a normative juridical analysis that relies on the ability of legal argumentation, legal interpretation, and legal reasoning related to criminal provisions in pornography law. From the results of research have found that criminal provisions in the law number 44 of 2008 on pornography is quite clear that everyone who access on porn sites on the internet threatened with criminal sanctions. Juridically, criminal provisions in pornography law provide legal certainty is quite clear.

  3. Adaptive Reactive Rich Internet Applications

    Rich Internet Applications significantly raise the user experience compared with legacy page-based Web applications because of their highly responsive user interfaces. Although this is a tremendous advance, it does not solve the problem of the one-size-fits-all approach1 of current Web applications. So although Rich Internet Applications put the user in a position to interact seamlessly with the Web application, they do not adapt to the context in which the user is currently working. In this paper we address the on-the-fly personalization of Rich Internet Applications. We introduce the concept of ARRIAs: Adaptive Reactive Rich Internet Applications and elaborate on how they are able to adapt to the current working context the user is engaged in. An architecture for the ad hoc adaptation of Rich Internet Applications is presented as well as a holistic framework and tools for the realization of our on-the-fly personalization approach. We divided both the architecture and the framework into two levels: offline/design-time and online/run-time. For design-time we explain how to use ontologies in order to annotate Rich Internet Applications and how to use these annotations for conceptual Web usage mining. Furthermore, we describe how to create client-side executable rules from the semantic data mining results. We present our declarative lightweight rule language tailored to the needs of being executed directly on the client. Because of the event-driven nature of the user interfaces of Rich Internet Applications, we designed a lightweight rule language based on the event-condition-action paradigm.2 At run-time the interactions of a user are tracked directly on the client and in real-time a user model is built up. The user model then acts as input to and is evaluated by our client-side complex event processing and rule engine.

  4. A Comparison of Internet-Based Participant Recruitment Methods: Engaging the Hidden Population of Cannabis Users in Research

    Elizabeth Clare Temple

    2011-01-01

    Full Text Available While a growing number of researchers are embracing Internet-based data collection methods, the adoption of Internet-based recruitment methods has been relatively slow. This may be because little is known regarding the relative strengths and weaknesses of different methods of Internet-based participant recruitment, nor how these different recruitment strategies impact on the data collected. These issues are addressed in this article with reference to a study comparing the effectiveness of three Internet-based strategies in recruiting cannabis users for an online study. Consideration of the recruitment data leads us to recommend that researchers use multipronged Internet-based recruitment campaigns with appropriately detailed recruitment messages tailored to the population of interest and located carefully to ensure they reach the intended audience. Further, we suggest that building rapport directly with potential participants, or utilising derived rapport and implicit endorsements, is an important aspect of successful Internet-based participant recruitment strategies.

    There currently are few web-based resources written in Spanish providing oncology-specific information. This study examines utilization of Spanish-language oncology web-based resources and evaluates oncology-related Internet browsing practices of Spanish-speaking patients. OncoLink (http://www.oncolink.org) is the oldest and among the largest Internet-based cancer information resources. In September 2005, OncoLink pioneered OncoLink en español (OEE) (http://es.oncolink.org), a Spanish translation of OncoLink. Internet utilization data on these sites for 2006 to 2007 were compared. Visits to OncoLink rose from 4,440,843 in 2006 to 5,125,952 in 2007. OEE had 204,578 unique visitors and 240,442 visits in 2006, and 351,228 visitors and 412,153 visits in 2007. Although there was no time predilection for viewing OncoLink, less relative browsing on OEE was conducted during weekends and early morning hours. Although OncoLink readers searched for information on the most common cancers in the United States, OEE readers most often search for gastric, vaginal, osteosarcoma, leukemia, penile, cervical, and testicular malignancies. Average visit duration on OEE was shorter, and fewer readers surveyed OEE more than 15 minutes (4.5% vs. 14.9%, P users of web-based oncology resources are increasingly using the Internet to supplement their cancer knowledge. Limited available resources written in Spanish contribute to disparities in information access and disease outcomes. Spanish-speaking oncology readers differ from English-speaking readers in day and time of Internet browsing, visit duration, Internet search patterns, and types of cancers searched. By acknowledging these differences, content of web-based oncology resources can be developed to best target the needs of Spanish-speaking viewers.

    Fixsen, Alison M; Ridge, Damien

    2017-11-01

    Benzodiazepines are a group of drugs used mainly as sedatives, hypnotics, antiepileptics, and muscle relaxants. Consumption is recommended for 2 to 4 weeks only, due to fast onset of dependency and potentially distressing withdrawal symptoms. Few peer-review studies have drawn on the user experiences and language to appreciate firsthand experiences of benzodiazepine withdrawal or discontinuation syndrome. We looked extensively at patient stories of benzodiazepine withdrawal and recovery on Internet support sites and YouTube. Our analysis indicated that users employ rich metaphors to portray the psychologically disturbing and protracted nature of their suffering. We identified seven major themes: hell and isolation, anxiety and depression, alienation, physical distress, anger and remorse, waves and windows, and healing and renewal. By posting success stories, ex-users make known that "healing" can be a long, unpredictable process, but distress does lessen, and recovery can happen.

    2016-03-22

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

    Full Text Available The paper reports a study carried out on the utilisation of the Internet by agricultural science teachers in Lagos state focusing on uses, practices, and barriers. A questionnaire was developed based on literature and was administered to 300 agricultural science teachers in Lagos schools. 275 questionnaires properly completed were analyzed. Data reveal that 130 teachers are using the Internet for teaching agricultural science in classrooms as well as for various activities that enhance their professional development. Nevertheless, it was found that agricultural science teachers in Lagos State have not fully utilised the Internet because of barriers related to time factor, accessibility, and facilities. It is suggested that for the proliferation of Internet practices, there needs to be an increase in funding for technology, an introduction of computer/technology education, a provision of pedagogical training for teachers, and a provision of administrational support.

    2016-04-01

    Full Text Available The simple drawing style of Japanese animated pornography (hentai and the incomplete messages transmitted through the handling short video clips instead of complete pornographic films or series on the Internet create a space in which users can reinterpret the content themselves and assign it meanings different to those originally intended by anime creators, the subculture or suggested by researchers. Based on the porn categories specific to the hentai genre, and keeping in mind the context and content of complete animated Japanese pornographic films, and the attitudes of their users, I will analyze the perspectives of users of short videos of both animated and feature porn on the internet. Through the use of an ethnotaxonomic approach, cognitive schemes and relations between categories have been uncovered. The self-reliance and distance of “alternative” subcultures represented through masturbation, sexual inferiority due to hypermasculine messages conveyed by big black penises as well as violence which does not allow the victim passive regression represented through the abuse of a teenage girl who is supposedly 18 years old, represent messages which correspond with the yaoi, tentacle rape and lolicon subgenres, as well as a subjective perspective in which any user behavior on the internet is legitimate, because of the users’ view that society doesn’t protect them, but protects those who supposedly do not deserve it. The oppressive force and villain of hentai narratives in pornographic feature films is the hyper-passivity of (not allowing instant gratification, which aligns with the value assigned to the speed and availability of information in the “virtual” field.

    Bereavement by suicide is associated with a number of consequences including poor mental health outcomes and increased suicide risk. Despite this, the bereaved by suicide may be reluctant to seek help from friends, family, and professionals. Internet forums and social networking sites are a popular avenue of support for the bereaved, but to date there is a lack of research into their use and efficacy. To survey users of suicide bereavement Internet forums and Facebook groups regarding their help-seeking behaviors, use of forums, and perceived benefits and limitations of such use. This study employed a cross-sectional design in which users of suicide bereavement Internet forums and Facebook groups completed an anonymous online survey. Participants were 222 users of suicide bereavement Internet forums. Most participants (93.2%) had sought face-to-face help from sources other than Internet forums, but were more likely to seek help in the near future from informal rather than formal sources. Forums were perceived as highly beneficial and there were few limitations. The generalizability of these results to other internet forums may be limited. Additionally, we were not able to examine differences between forums in terms of quality or user-reported efficacy. Finally, the data reflects the subjective views of forum users, which may differ from the views of moderators or experts. Internet forums, including Facebook groups, appear to be a useful adjunct to face-to-face help-seeking for supporting those who have been bereaved by suicide.

    Internet use has become an increasingly common leisure time activity among Chinese citizens. The association between Internet use and engagement in leisure activities is especially unclear among China population. This study aims to investigate Internet usage and to determine whether active Internet use is a marker for low or high levels of leisure time activities. With the use of a face-to-face structured questionnaire interview, a total of 2,400 respondents who met all screening requirements were surveyed to answer the questions in eight major cities in China. 66.2% (n = 1,589) of all respondents were identified as Internet users. Of these Internet users, 30.0%, 24.1%, 26.4%, and 19.6% were clustered as "informative or instrumental users," "entertainment users," "communication users," and "advanced users," respectively. Regarding time spent on Internet use in leisure time, more than 96% reported going online in non-work situations, and 26.2% (n = 416) were classified as "heavy Internet users." A logistic regression analysis revealed that there were significant differences in some leisure activities between non-Internet users and Internet users, with an observed one-unit increase in the leisure time dependence category increasing the probability of engaging in mental or social activities. In contrast, Internet users were less engaged in physical exercise-related activities. In addition, advanced Internet users were generally more active in leisure time activities than non-Internet users and other types of users. Internet use is one of very common leisure activities in Chinese citizens, and age, gender, income, and education are the key factors affecting Internet access. According to different types of leisure activities, Internet usage has different impacts on leisure activity engagement. High Internet dependence has no significant negative influence on engagement in mental or social leisure activities, but this group respondent tended to be less engaged in

    Abstract. Looking back over 15 years of demonstrating visual phenomena and optical illusions on the Internet, I will discuss two major topics. The first concerns the methodology used to present interactive visual experiments on the web, with respect to (a) wide accessibility, ie independent of browser and platform, (b) capable and elegant graphic user interface, (c) sufficient computational power, (d) ease of development and, finally, (e) future-proofing in an ever-changing online environment. The second major topic addresses some aspects of user behaviour, mainly temporal patterns (eg changes over weeks. years, long-term), which reveal that there are more visitors during office hours.

    2017-03-01

    Background and aims The "Internet addiction" paradigm has been criticized for several shortcomings, including inattention to specific online behaviors, not distinguishing the Internet from other media, insufficient focus on comorbidities, and definitions that do not take into account the constant access now possible. The paradigm's biggest casualty, however, may be that it has diverted attention away from subtle personality changes that seem to occur online, including in users who cannot be considered "addicted" under any definition. Methods A narrative assessment of the literature was conducted, focusing on the Internet's effects on personality traits as revealed in studies of Internet users. Results Impulsivity, narcissism, and aggression are some of the personality traits that seem to be nurtured by the Internet, with possible negative offline consequences. Discussion Ignoring the Internet's subtle effects on personality as we embrace an addiction model that implies severe pathology makes the majority of Internet users feel deceptively immune to the psychological effects of new technologies. It also limits our understanding of the big cultural shifts that are happening as a result. Conclusion The Internet's potentially negative effect on personality, and by extension on society at large, is a fundamental part of online psychology, one well worthy of further investigation.

    Introduction Internet use has become an increasingly common leisure time activity among Chinese citizens. The association between Internet use and engagement in leisure activities is especially unclear among China population. This study aims to investigate Internet usage and to determine whether active Internet use is a marker for low or high levels of leisure time activities. Methods/Principal Findings With the use of a face-to-face structured questionnaire interview, a total of 2,400 respondents who met all screening requirements were surveyed to answer the questions in eight major cities in China. 66.2% (n = 1,589) of all respondents were identified as Internet users. Of these Internet users, 30.0%, 24.1%, 26.4%, and 19.6% were clustered as “informative or instrumental users,” “entertainment users,” “communication users,” and “advanced users,” respectively. Regarding time spent on Internet use in leisure time, more than 96% reported going online in non-work situations, and 26.2% (n = 416) were classified as “heavy Internet users.” A logistic regression analysis revealed that there were significant differences in some leisure activities between non-Internet users and Internet users, with an observed one-unit increase in the leisure time dependence category increasing the probability of engaging in mental or social activities. In contrast, Internet users were less engaged in physical exercise-related activities. In addition, advanced Internet users were generally more active in leisure time activities than non-Internet users and other types of users. Conclusion/Significance Internet use is one of very common leisure activities in Chinese citizens, and age, gender, income, and education are the key factors affecting Internet access. According to different types of leisure activities, Internet usage has different impacts on leisure activity engagement.

This study was performed to investigate the association between general health and internet addiction.Materials and Methods: In this descriptive study a total number of 375 students (189 female and 186 male were randomly selected from Sistan and Baluchestan University between 2007 to 2008. Using the internet addiction test (IAT, the students were divided into two groups: ordinary users and addicted users of internet. The general health questionnaire (GHQ was used to compare these two groups. The SPSS software and t test were used to analyze the data and P<0.01 was significant.Results: The general health of internet-addicted users in comparison with ordinary users was at a higher risk (P<0.01. But the difference between two groups in general health and disorders of social function were not statistically significant. Conclusion: Depression and anxiety were common in internet addicted users and it was correlated to the amount of time that they were allocating to it.

    Although Internet games have been proven to be addictive, only a few game players develop online gaming addiction. A large number of players play online games recreationally without being addicted to it. These individuals are defined as recreational Internet gaming users (RGU). So far, no research has investigated decision-making and impulse control in RGU. In the current study, we used delay discounting (DD) task and probabilistic discounting (PD) task to examine decision-making and impulse control in 20 healthy controls, 20 subjects with Internet gaming disorder (IGD) and 23 RGU during fMRI scanning. At the behavioral level, RGU showed lower DD rate and higher PD rate than subjects with IGD and there was no significant difference between RGU and healthy controls on the DD and PD rates. At the neural level, RGU showed increased neural response in the parahippocampal gyrus, the anterior cingulate cortex, the medial frontal gyrus and the inferior frontal gyrus as compared with subjects with IGD. These brain regions may play an important role in preventing RGU from developing addiction. The results suggest that the RGU are capable of inhibiting impulse due to additional cognitive endeavor and the subjects with IGD have deficit in decision-making and impulsive control, which are associated with brain dysfunction. © 2016 Society for the Study of Addiction.

    Full Text Available That internet is developing fast and its cost is becoming cheaper rapidly increases the number of people using this technology. Although internet provides miscellaneous benefits for the users, it also causes them to encounter certain difficulties. Particularly, those young people, who leave their families to study at a university spend most of their time on the internet because of such personal and social problems as having low satisfaction from life, having social anxiety, not being able to communicate or establish relationships and feeling lonely. And this could lead to internet addiction in young people. The aim of this study is to discuss the internet addiction levels of freshmen and sophomores at university within the scope of educational theories and to predict addiction according to various variables. Survey method is used in the study. The study was carried out on 329 freshmen and sophomores studying at economics, science teaching, primary school mathematics education, primary school teaching and social sciences teaching departments of Bartın University in the second term of 2012-2013 academic year. As an end of the study, factors that cause to internet addiction and what can be done to remove these factors are discussed within theoretical framework.

    2014-01-01

    Abstract A synthetic cathinone called 4-methylethcathinone (4-MEC) emerged online in 2010, and was cyber-marketed to be a replacement for mephedrone. The study aimed to present user experiences of 4-MEC as reported on the Internet, with a focus on user profiles, sourcing and product characteristics, routes of administration, dosage, positive and undesirable effects, and comparisons to mephedrone. Twenty-three individual, anonymous trip reports of the sole use of 4-MEC, and 112 screenshots of general 4-MEC user discussion boards, were taken from a purposeful sample of public drug-related sites. A content textual analysis was conducted on extracted qualitative information and produced 41 categories compiled into five general themes: "Type of 4-MEC user"; "Sourcing, informed decision making, product characteristics, and quality assurance"; "Routes of administration, gauging of dosage, and consumption of other drugs"; "Time course effects and outcomes"; and "Comparisons with mephedrone." 4-MEC is sold as white beads, crystalline shards, or green balls. User motives centered on curiosity, pricing, and ease of web sourcing. Oral, nasal, injecting, eyeball, and rectal routes of administration were described. Testing for purity, "allergy testing," and gauging of dosage were common. Users described euphoric but short-lived effects, with little comedown. Continued research is vital to inform harm reduction.

    Since Internet surfing became a daily activity, people have changed their behavior. This research analyzes the causes of problematic Internet use through an online survey, where 1,094 samples were collected. Based on the results of structural equation modeling analysis, the following conclusions are reached: First, novelty, security, and efficiency increase users' online trust. Second, information and efficiency enhance users' sharing and anonymity online. Third, greater trust in Internet environments leads to an increase in a user's cognitive bias toward online behavioral responsibility and Internet addiction. Fourth, a user's attitude toward online sharing further increases the cognitive bias toward online copyright. Fifth, a user's attitude toward anonymity increases cognitive bias toward online copyright, online behavioral responsibility, and deepens Internet addiction.

    It is now well established that pursuing generic solutions to what seem are common problems in Earth science data access and use can often lead to disappointing results for both system developers and the intended users. This presentation focuses on real-world experience of managing a large and complex data system, NASAs Earth Science Data and Information Science System (EOSDIS), whose mission is to serve both broad user communities and those in smaller niche applications of Earth science data and services. In the talk, we focus on our experiences with known data user obstacles characterizing EOSDIS approaches, including various technological techniques, for engaging and bolstering, where possible, user experiences with EOSDIS. For improving how existing and prospective users discover and access NASA data from EOSDIS we introduce our cross-archive tool: Earthdata Search. This new search and order tool further empowers users to quickly access data sets using clever and intuitive features. The Worldview data visualization tool is also discussed highlighting how many users are now performing extensive data exploration without necessarily downloading data. Also, we explore our EOSDIS data discovery and access webinars, data recipes and short tutorials, targeted technical and data publications, user profiles and social media as additional tools and methods used for improving our outreach and communications to a diverse user community. These efforts have paid substantial dividends for our user communities by allowing us to target discipline specific community needs. The desired take-away from this presentation will be an improved understanding of how EOSDIS has approached, and in several instances achieved, removing or lowering the barriers to data access and use. As we look ahead to more complex Earth science missions, EOSDIS will continue to focus on our user communities, both broad and specialized, so that our overall data system can continue to serve the needs of

    Problematic internet use (PIU) has been suggested as in need of further research with a view to being included as a disorder in future Diagnostic and Statistical Manual (DSM) of the American Psychiatric Association, but lack of knowledge about the impact of internet cessation on physiological function remains a major gap in knowledge and a barrier to PIU classification. One hundred and forty-four participants were assessed for physiological (blood pressure and heart rate) and psychological (mood and state anxiety) function before and after an internet session. Individuals also completed a psychometric examination relating to their usage of the internet, as well as their levels of depression and trait anxiety. Individuals who identified themselves as having PIU displayed increases in heart rate and systolic blood pressure, as well as reduced mood and increased state of anxiety, following cessation of internet session. There were no such changes in individuals with no self-reported PIU. These changes were independent of levels of depression and trait anxiety. These changes after cessation of internet use are similar to those seen in individuals who have ceased using sedative or opiate drugs, and suggest PIU deserves further investigation and serious consideration as a disorder.

    Despite the growing evidence of the benefits of physical activity (PA) in individuals with rheumatoid arthritis (RA), the majority is not physically active enough. An innovative strategy is to engage lead users in the development of PA interventions provided over the internet. The aim was to explore lead users' ideas and prioritization of core features in a future internet service targeting adoption and maintenance of healthy PA in people with RA. Six focus group interviews were performed with a purposively selected sample of 26 individuals with RA. Data were analyzed with qualitative content analysis and quantification of participants' prioritization of most important content. Six categories were identified as core features for a future internet service: up-to-date and evidence-based information and instructions, self-regulation tools, social interaction, personalized set-up, attractive design and content, and access to the internet service. The categories represented four themes, or core aspects, important to consider in the design of the future service: (1) content, (2) customized options, (3) user interface and (4) access and implementation. This is, to the best of our knowledge, the first study involving people with RA in the development of an internet service to support the adoption and maintenance of PA.Participants helped identifying core features and aspects important to consider and further explore during the next phase of development. We hypothesize that involvement of lead users will make transfer from theory to service more adequate and user-friendly and therefore will be an effective mean to facilitate PA behavior change.

    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

    The Internet goose has laid countless golden eggs, along with a growing number of rotten ones. But it's the rotten ones that now tempt commercial, governmental, and consumer interests to threaten the Internet's uniquely creative power. The expediently selected, almost accidentally generative properties of the Internet - its technical openness, ease of access and mastery, and adaptability - have combined, especially when coupled with those of the PC, to produce an unsurpassed environment for innovative experiment. Those same properties, however, also make the Internet hospitable to various forms of wickedness: hacking, porn, spam, fraud, theft, predation, and attacks on the network itself. As these undesirable phenomena proliferate, business, government, and many users find common cause for locking down Internet and PC architecture in the interests of security and order. PC and Internet security vulnerabilities are a legitimate menace. However, the most likely reactions - if they are not forestalled - will be at least as unfortunate as the security problems themselves. Consider the growing profusion of "tethered appliances" - devices whose functions cannot readily be altered by their owners (think TiVo). Such appliances take Internet innovations and wrap them up in a neat, easy-to-use package, which is good - but only if the Internet and PC can remain sufficiently in the center of the digital ecosystem to produce the next round of innovations and to generate competition. People buy these devices for their convenience or functionality and may appreciate the fact that they are safer to use (they limit the damage users can do through ignorance or carelessness). But the risk is that users, by migrating to such appliances, will unwittingly trade away the future benefits of generativity - a loss that will go unappreciated even as innovation tapers off.

    A patient discussing Internet health information with a health care provider (referred to as "patient-provider communication about Internet health information") can contribute positively to health outcomes. Although research has found that once Internet access is achieved, there are no ethnic differences in Internet health information seeking, it is unclear if there are ethnic differences in patient-provider communication about Internet health information. To help fill this gap in the literature, the National Cancer Institute's Health Information National Trends Survey 2005 was analyzed with Stata 9. Two sets of logistic regression analyses were conducted, one for a subsample of Internet users (n = 3,244) and one for a subsample of Internet users who are first-generation immigrants (n = 563). The dependent variable was patient-provider communication about Internet health information, which assessed whether survey participants had discussed online health information with a health care provider. The predictor variables included trust of health care provider, trust of online health information, Internet use, health care coverage, frequency of visits to health care provider, health status, and demographics. Among all Internet users, Whites had higher levels of patient-provider communication about Internet health information than Blacks and Asians. Similarly, among Internet users who are immigrants, Whites had higher levels of patient-provider communication about Internet health information than Blacks and Asians. While the digital divide is narrowing in terms of Internet access, racial differences in patient-provider communication about Internet health information may undermine the potential benefits of the information age.

    Survivorship care plans have been recommended by the Institute of Medicine for all cancer survivors. We implemented an Internet-based tool for creation of individualized survivorship care plans. To our knowledge, this is the first tool of this type to be designed and made publicly accessible. To investigate patterns of use and satisfaction with an Internet-based tool for creation of survivorship care plans. OncoLife, an Internet-based program for creation of survivorship care plans, was designed by a team of dedicated oncology nurses and physicians at the University of Pennsylvania. The program was designed to provide individualized, comprehensive health care recommendations to users responding to queries regarding demographics, diagnosis, and cancer treatments. After being piloted to test populations, OncoLife was made publicly accessible via Oncolink, a cancer information website based at the University of Pennsylvania which averages 3.9 million page views and over 385,000 unique visits per month. Data entered by anonymous public users was maintained and analyzed. From May 2007 to November 2008, 3343 individuals utilized this tool. Most (63%) identified themselves as survivors, but also health care providers (25%) and friends/family of survivors (12%). Median age at diagnosis was 48 years (18-100+), and median current age 51 (19-100+). Most users were Caucasian (87%), female (71%), and college-educated (82%). Breast cancer was the most common diagnosis (46%), followed by hematologic (12%), gastrointestinal (11%), gynecologic (9%), and genitourinary (8%). Of all users, 84% had undergone surgery, 80% chemotherapy, and 60% radiotherapy. Half of users (53%) reported receiving follow-up care from only an oncologist, 13% only a primary care provider (PCP), and 32% both; 12% reported having received survivorship information previously. Over 90% of users, both survivors and health care providers, reported satisfaction levels of "good" to "excellent" using this tool

    Internet use in Russia has been growing steadily. In the last four years the number of Russian Internet users grew from a few hundred thousand to over one million. Russian websites are diverse, and range from educational-informative to purely entertaining. This paper discusses several interesting and controversial Russian websites and possible implications associated with their use. It aims to understand and analyze a typical Internet user in Russia, by answering questions about their interests and demographics. The paper also discusses several other studies that were conducted in Russia on Internet use and looks at the currently available psychological resources on the Russian Internet.

    Infodemiology studies for suicide prevention have become increasingly common in recent years. However, the association between Twitter use and suicide has only been partially clarified. This study examined the association between suicide-related tweets and suicidal behaviour to identify suicidal young people on the Internet. A cross-sectional survey was conducted using Internet survey panels (n=220,848) comprising users in their 20s, through a major Japanese Internet survey company. Final analyses included the data of 1000 participants. Of the participants (n=1000) used in the final analysis, 61.3% were women and the mean age was 24.9 years (SD=2.9, range=20-29). Logistic regression analyses showed that tweeting "want to die" and "want to commit suicide" was significantly related to suicidal ideation and behaviour. Lifetime suicide attempts, the most powerful predictor of future suicide out of all suicidal behaviours, were more strongly associated with tweeting "want to commit suicide" than tweeting "want to die". Having a Twitter account and tweeting daily were not associated with suicidal behaviour. An online panel survey has some inherent biases, such as coverage bias. Respondents were already registered as members of a particular Internet survey company in Japan, which limits the possibility of generalization. Twitter logs may be used to identify suicidal young Internet users. This study provides a basis for the early identification of individuals at high risk for suicide. Copyright © 2014 Elsevier B.V.

    The purpose of the current study was to evaluate possible overlapping substance abuse and internet addiction in a large, uniformly sampled population, ranging in age from 13 to 18 years. Participants (N=73,238) in the current study were drawn from the 6th Korea Youth Risk Behavior Web-based Survey (KYRBWS-V) for students from 400 middle schools and 400 high schools in 16 cities within South Korea. Of adolescent internet users, 85.2% were general users (GU), 11.9% were users with potential risk for internet addiction (PR), and 3.0% were users with high risk for internet addiction (HR). There was a difference in the number of students with alcohol drinking among the GU, PR, and HR groups (20.8% vs 23.1% vs 27.4%). There was a difference in the number of students who smoked among the GS, PR, and HR groups (11.7% vs 13.5% vs 20.4%). There was a difference in the number of students with drug use among the GU, PR, and HR groups (1.7% vs 2.0% vs 6.5%). After adjusting for sex, age, stress, depressed mood, and suicidal ideation, smoking may predict a high risk for internet addiction (OR=1.203, p=0.004). In addition, drug use may predict a high risk for internet addiction (OR=2.591, paddiction have vulnerability for addictive behaviors, co-morbid substance abuse should be evaluated and, if found, treated in adolescents with internet addiction.

    Full Text Available This study aims to find out to what extent the Internet users in line with media literacy. According to Indonesia Internet Service Provider Association (APJII and BPS Statistic Indonesia, it was found that Internet users in Indonesia have grown since three years ago up to 13% or become 71.19 million people until the end of 2013. According to research survey MarkPlus Insight, “netizen” or Internet users who spend more than three hours per day on Internet. Moreover, they are increasing from 24,2 Million people in 2012 and become 31,7 million people in 2013. This research used qualitative method by gathering the data through Focus Group Discussion (FGD to private university students who spent for Internet 5 hours per day and less than 5 hours per day. The theory used in this research was media literacy. The result of this research stated that students who accessed the Internet below 5 hours per day were already busy with work and not too intense in using the Internet either via smartphone or a computer. Different findings came up from the students who accessed the Internet over 5 hours per day. Most of the time, they used the Internet for social media and instant messaging (instant messenger through smartphones. Critical attitude towards the media message depends on the informants’ interest toward the information.

    This paper investigates how individual consumers may differ in their information search behavior in health care decision-making. Results indicate that most consumers still use word-of-mouth as a primary information source for health care decisions. However, usage of the Internet is increasing. The results of this study indicate that consumers who are most likely to use the Internet for health care information are single, younger, and less educated, whereas consumers who are most likely to use word-of-mouth are middle-aged, married, with higher income and higher education. Surprisingly, no significant gender difference was found in information search behavior for health care decision-making. The results also suggest that consumers with the highest tendency to use word-of-mouth are also the lowest users of the Internet in health care decision-making. Implications of these findings are discussed.

    In response to the budget environment and to expand on the International Space Station (ISS) Fluids and Combustion Facility (FCF) Combustion Integrated Rack (CIR), common hardware approach, the NASA Combustion Science Program shifted focus in 1999 from single investigator PI (Principal Investigator)-specific hardware to multi-user 'Minifacilities'. These mini-facilities would take the CIR common hardware philosophy to the next level. The approach that was developed re-arranged all the investigations in the program into sub-fields of research. Then common requirements within these subfields were used to develop a common system that would then be complemented by a few PI-specific components. The sub-fields of research selected were droplet combustion, solids and fire safety, and gaseous fuels. From these research areas three mini-facilities have sprung: the Multi-user Droplet Combustion Apparatus (MDCA) for droplet research, Flow Enclosure for Novel Investigations in Combustion of Solids (FEANICS) for solids and fire safety, and the Multi-user Gaseous Fuels Apparatus (MGFA) for gaseous fuels. These mini-facilities will develop common Chamber Insert Assemblies (CIA) and diagnostics for the respective investigators complementing the capability provided by CIR. Presently there are four investigators for MDCA, six for FEANICS, and four for MGFA. The goal of these multi-user facilities is to drive the cost per PI down after the initial development investment is made. Each of these mini-facilities will become a fixture of future Combustion Science NASA Research Announcements (NRAs), enabling investigators to propose against an existing capability. Additionally, an investigation is provided the opportunity to enhance the existing capability to bridge the gap between the capability and their specific science requirements. This multi-user development approach will enable the Combustion Science Program to drive cost per investigation down while drastically reducing the time

    Internet use is an integral part of our everyday activities; however, Internet use may become problematic and harmful in a minority of cases. The majority of reported prevalence rates of problematic Internet use refer to adolescent samples, whereas epidemiological studies on representative adult populations are lacking. This study aimed to reveal the prevalence and characteristics of problematic Internet use in Slovenia. Problematic Internet Use Questionnaire (PIUQ) was included in European Health Interview Study (EHIS) on representative Slovenian sample. The frequency of Internet use and problematic Internet use were both assessed. 59.9% of Slovenian adult population uses the Internet daily, and 3.1% are at risk of becoming problematic Internet users, 11% in the age group from 20 to 24 years. Those being at risk for becoming problematic Internet users are younger (mean age 31.3 vs. 48.3 for non-problematic users), more likely to be males (3.6% of males, whereas 2.6% of females are affected), students (12.0%), unemployed (6.3%) or unable to work (8.7%), single (6.5%), with high education (4.5%). Regression analysis revealed that the strongest predictor of being at risk for problematic Internet use is age (ß=-0.338, p<0.001); followed by high educational level (ß=0.145; p<0.001) and student status (ß=0.136; p<0.001). 3.1% of Slovenian adult population are at risk of becoming problematic Internet users, whereas 3 out of 20 Slovenian adolescents aged from 18 to 19 years are at risk (14.6%). Prevention programs and treatment for those affected are paramount, especially for the young generation.

    The aim of this study was to investigate Internet use habits and problematic Internet use (PIU) in Turkish adolescents. Participants were 3,975 undergraduate students, 7.6% of whom used the Internet for more than 12 hours weekly. The Online Cognition Scale (OCS) was used. The most common purpose for using the Internet was playing games, followed by general information search. Female users mostly preferred searching for general information; male users preferred playing games (p game was violent games. While preference for strategy and fantasy role-play (FRP) games increased with age, preference for other games decreased (p games, followed by FRP, strategy, and sports and motor racing games. Computers and the Internet are useful, important inventions, but like other inventions, if used improperly, they may be harmful. Risk of harm raises concerns about who should use the Internet and computers, and where, when, and why the Internet and computers should be used.

    In 1998 the Swedish noncommercial public health service Infomedica opened an Ask the Doctor service on its Internet portal. At no charge, anyone with Internet access can use this service to ask questions about personal health-related and disease-related matters. To study why individuals choose to consult previously-unknown doctors on the Internet. Between November 1, 2001, and January 31, 2002 a Web survey of the 3622 Ask the Doctor service users, 1036 men (29%) and 2586 (71%) women, was conducted. We excluded 186 queries from users. The results are based on quantitative and qualitative analysis of the answers to the question "Why did you choose to ask a question at Infomedica's 'Ask the Doctor' service?" 1223 surveys were completed (response rate 36 %). Of the participants in the survey 322 (26%) were male and 901 (74%) female. As major reasons for choosing to consult previously-unknown doctors on the Internet participants indicated: convenience (52%), anonymity (36%), "doctors too busy" (21%), difficult to find time to visit a doctor (16%), difficulty to get an appointment (13%), feeling uncomfortable when seeing a doctor (9%), and not being able to afford a doctors' visit (3%). Further motives elicited through a qualitative analysis of free-text answers were: seeking a second opinion, discontent with previous doctors and a wish for a primary evaluation of a medical problem, asking embarrassing or sensitive questions, seeking information on behalf of relatives, preferring written communication, and (from responses by expatriates, travelers, and others) living far away from regular health care. We found that that an Internet based Ask the Doctor service is primarily consulted because it is convenient, but it may also be of value for individuals with needs that regular health care services have not been able to meet.

  4. Tagging: An Organization Scheme for the Internet

    Directory of Open Access Journals (Sweden)

    2010-03-01

    Full Text Available How should the information on the Internet be organized? This question and the possible solutions spark debates among people concerned with how we identify, classify, and retrieve Internet content. This paper discusses the benefits and the controversies of using a tagging system to organize Internet resources. Tagging refers to a classification system where individual Internet users apply labels, or tags, to digital resources. Tagging increased in popularity with the advent of Web 2.0 applications that encourage interaction among users. As more information is available digitally, the challenge to find an organizational system scalable to the Internet will continue to require forward thinking. Trained to ensure access to a range of informational resources, librarians need to be concerned with access to Internet content. Librarians can play a pivotal role by advocating for a system that supports the user at the moment of need. Tagging may just be the necessary system.

    Over the past two decades there was an upsurge of the use of Internet in human life. With this continuous development, Internet users are able to communicate with any part of the globe, to shop online, to use it as a mean of education, to work remotely and to conduct financial transactions. Unfortunately, this rapid development of the Internet has a detrimental impact in our life, which leads to various phenomena such as cyber bullying, cyber porn, cyber suicide, Internet addiction, social isolation, cyber racism etc. The main purpose of this paper is to record and analyze all these social and psychological effects that appears to users due to the extensive use of the Internet. This review study was a thorough search of bibliography data conducted through Internet and library research studies. Key words were extracted from search engines and data bases including Google, Yahoo, Scholar Google, PubMed. The findings of this study showed that the Internet offers a quick access to information and facilitates communication however; it is quite dangerous, especially for young users. For this reason, users should be aware of it and face critically any information that is handed from the website.

    Background Telecommunication is limited or even impossible for more than one-thirds of all cochlear implant (CI) users. Objective We sought therefore to study the impact of voice quality on speech perception with voice over Internet protocol (VoIP) under real and adverse network conditions. Methods Telephone speech perception was assessed in 19 CI users (15-69 years, average 42 years), using the German HSM (Hochmair-Schulz-Moser) sentence test comparing Skype and conventional telephone (public switched telephone networks, PSTN) transmission using a personal computer (PC) and a digital enhanced cordless telecommunications (DECT) telephone dual device. Five different Internet transmission quality modes and four accessories (PC speakers, headphones, 3.5 mm jack audio cable, and induction loop) were compared. As a secondary outcome, the subjective perceived voice quality was assessed using the mean opinion score (MOS). Results Speech telephone perception was significantly better (median 91.6%, P 15%) were not superior to conventional telephony. In addition, there were no significant differences between the tested accessories (P>.05) using a PC. Coupling a Skype DECT phone device with an audio cable to the CI, however, resulted in higher speech perception (median 65%) and subjective MOS scores (3.2) than using PSTN (median 7.5%, P<.001). Conclusions Skype calls significantly improve speech perception for CI users compared with conventional telephony under real network conditions. Listening accessories do not further improve listening experience. Current Skype DECT telephone devices do not fully offer technical advantages in voice quality. PMID:28438727

    Internet mapping applications for geologic data allow simultaneous data delivery and collection, enabling quick data modification while efficiently supplying the end user with information. Utilizing Web-based technologies, the Colorado Geological Survey's Colorado Late Cenozoic Fault and Fold Database was transformed from a monothematic, nonspatial Microsoft Access database into a complex information set incorporating multiple data sources. The resulting user-friendly format supports easy analysis and browsing. The core of the application is the Microsoft Access database, which contains information compiled from available literature about faults and folds that are known or suspected to have moved during the late Cenozoic. The database contains nonspatial fields such as structure type, age, and rate of movement. Geographic locations of the fault and fold traces were compiled from previous studies at 1:250,000 scale to form a spatial database containing information such as length and strike. Integration of the two databases allowed both spatial and nonspatial information to be presented on the Internet as a single dataset (http://geosurvey.state.co.us/pubs/ceno/). The user-friendly interface enables users to view and query the data in an integrated manner, thus providing multiple ways to locate desired information. Retaining the digital data format also allows continuous data updating and quick delivery of newly acquired information. This dataset is a valuable resource to anyone interested in earthquake hazards and the activity of faults and folds in Colorado. Additional geologic hazard layers and imagery may aid in decision support and hazard evaluation. The up-to-date and customizable maps are invaluable tools for researchers or the public.

    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.

    Background The use of Internet has now become indispensable, and the technology has revolutionized the medical education and practice worldwide. Currently, medical students and professionals have an enormous opportunity to keep them always updated with the exponential growth of knowledge because of potential progression of Internet throughout the world that enables them to become a lifelong learner. Internet addiction is a widespread phenomenon among students and academicians at universities in Malaysia. Students use the Internet for recreational purpose and personal and professional development. The Internet has become an integral part of day-to-day life of the university students, including medical students. The aim of the present study was to examine the Internet use and addiction among students of Universiti Sultan Zainal Abidin, Malaysia. Methods This was a cross-sectional study in which a questionnaire, Internet Addiction Diagnostic Questionnaire, developed by the Center for Internet Addiction, USA, was used. One hundred forty-nine medical students of Universiti Sultan Zainal Abidin participated in this study. Data were analyzed using Statistical Package for the Social Sciences software. Results The mean scores were 44.9±14.05 and 41.4±13.05 for male and female participants, respectively, which indicated that both the genders were suffering from mild Internet addiction. Conclusion This study shows almost similar level of Internet usage among medical students irrespective of their socioeconomic background, with no statistically significant (p>0.05) differences, except among the years of study (p=0.007). Overall, from the research data and having worked with this cohort very closely, Universiti Sultan Zainal Abidin medical students can be labeled as wonted and recurring users of the Internet. Nevertheless, it is very difficult to define as Internet addicts or pathological users of the Internet because of small sample size and cross-sectional study. PMID

    Full Text Available Introduction: Although e-health interventions are widely implemented as a supportive measure to smoking cessation, there is a lack of evidence in the feasibility of its application among Vietnamese youths, which is considered to be one of the most frequent internet using populations. This study assessed the quitting attempts among smokers and their preference and willingness to pay for smartphone-based cessation supporting applications in a sample of active internet users approached. Methods: A total of 1082 participants were recruited for the online-based survey from August to October 2015 in Vietnam. Information on sociodemographic characteristics, health information seeking behaviors on the internet, smoking status, quitting attempts and willingness to pay for smartphone-based cessation supporting applications were collected. Multivariate logistic regression was used to determine the associated factors with current smoking and willingness to pay for the smoking cessation application. Results: About 11% of participants were current smokers while 73.4% had attempted to quit smoking. Only 26.8% of the individuals indicated that they were willing to utilize a smartphone application to assist them in quitting. Participants who were male, had partners/spouse and lived at other places were more likely to smoke cigarette. Meanwhile, people who spent 50–70% of their online time to read health information were less likely to smoke. Results also show that living with family and never sharing health information on the internet were negatively associated with a participant’s willingness to pay for the smartphone application. Meanwhile, people who highly trusted health information were more likely to be willing to pay for the application. Conclusions: This prevalence of smoking and associated factors can provide potential indicators for creating several public health interventions in the new environment with the increasing development of information

    Full Text Available This presentation is aimed at briefly underlining the most important developments in informatics, following the introduction of the new informational techniques and technologies.Our presentation began by enumerating the programming languages used over time, by presenting the computers industry and computers generations. We have focused on numerous technical aspects, such as hardware structure; however the basis was represented by the way how information and computer networks are organized. At said point, an analysis was made of the Intranet and Internet, with a particular focus on the evolution of the Internet and its advantages and disadvantages. The Internet has represented and continues to represent a great challenge for its users, whereas as beneficial its advantages might be, the more dangerous it can become its use by some users in less controlled environments

  17. The novice and the expert: How gender and experience influence student participation, interest and learning in an Internet-based science project

    Mistler-Jackson, Megan Elizabeth

    The purpose of this study is to examine how gender issues influence middle school students' participation, interest and learning in an Internet-based science curriculum project. One central question is whether using the Internet for communication and collaboration might serve as an entree into science and computer technology for those who are otherwise disinterested. Five students and their teacher were observed for five weeks and interviewed at the end of their participation in the Journey North Internet-based science project. Other methods of data collection included field notes, journal writing, and document review. Data were analyzed using ethnographic and case study methodology. Results revealed that boys were viewed as science and computer experts by themselves and by their peers more often than girls, both when they were and were not more knowledgeable. Data also showed that the teacher's inexperience with computers and the Journey North project was a more significant factor in student learning than gender. Findings with two students support the notion that using the Internet for communication and collaboration may encourage participation in computer technology by students like them. These results add to literatures that document the gender gap in science and computing and complement research on the incorporation of the Internet in the classroom. This study examines participation and interest from students' points of view, confirms the central role teachers play in enacting network science projects effectively and identifies several challenges this teacher faced in learning to utilize new technologies.

    The importance of Internet architecture goes beyond the technical aspects. The architecture of Internet has a profound influence on the Internet-based economy in term of how the profits are shared by different market participants (Internet Server Provider, Internet Content Provider), since it is the physical foundation upon which the profit-sharing contracts are derived. In order to facilitate the continuing growth of the Internet, it is necessary to systematically study factors that curtail the Internet-based economy including the existing Internet architecture. In this paper, we used transaction cost economics and contract economics as new tools to analyse the contracts derived from the current Internet architecture. This study sheds light on how the macro characteristics of Internet architecture effect the microeconomical decisions of market participants. Based on the existing Internet architecture, we discuss the possibility of promoting Internet-based economy by encouraging user to connect their private stub network to the Internet and giving the user more right of self-governing.

    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.

    Full Text Available Nowadays, Internet banking is a service provided by all Romanian banks which has become a daily need for millions of users. This study contains a brief overview of the Internet banking services usage level in the European Union for the period 2007-2016. An increasing in the use of Internet banking services in the EU can be observed at the level of the analysed period. At the same time we compared the users (individuals aged 16 to 74 of Internet banking services to other European countries and we found that the users of the Internet banking services in Romania are still far below the European average but the trend is an upward one. In this study we have focused our attention only on Internet banking, as it is the most commonly used payment instrument in the Romanian practice of remote access payment instruments. The indicators considered in this study were the Internet banking users and the Internet users. We have used the model of the simple linear regression to highlight the existence of a relationship between the variables. In this respect we used statistical data taken from Eurostat and Romanian Ministry of Communications and Information Society as well as data provided by the Romanian National Institute of Statistics for the period 2009-2014. The results of the model have pointed out the fact that the rise of the number of Internet users leads to an increase of the number of Internet banking users.

    Full Text Available Internet congestion occurs when resource demands exceeds the network capacity. But, it is not the only reason. Congestion can happen on some users because some others user has higher sending rate. Then some users with lower sending rate will experience congestion. This partial congestion is caused by inexactly feedback. At this moment congestion are solved by the involvement of two controlling mechanisms. These mechanisms are flow/congestion control in the TCP source and Active Queue Management (AQM in the router. AQM will provide feedback to the source a kind of indication for the occurrence of the congestion in the router, whereas the source will adapt the sending rate appropriate with the feedback. These mechanisms are not enough to solve internet congestion problem completely. Therefore, this paper will explain internet congestion causes, weakness, and congestion control technique that researchers have been developed. To describe congestion system mechanisms and responses, the system will be simulated by Matlab.

    More advanced methods and models are needed to evaluate the participation of patients and citizens in the shared health care model that eHealth proposes. The goal of our study was to design and evaluate a predictive multidimensional model of eHealth usage. We used 2011 survey data from a sample of 13,000 European citizens aged 16-74 years who had used the Internet in the previous 3 months. We proposed and tested an eHealth usage composite indicator through 2-stage structural equation modelling with latent variables and measurement errors. Logistic regression (odds ratios, ORs) to model the predictors of eHealth usage was calculated using health status and sociodemographic independent variables. The dimensions with more explanatory power of eHealth usage were health Internet attitudes, information health Internet usage, empowerment of health Internet users, and the usefulness of health Internet usage. Some 52.39% (6811/13,000) of European Internet users' eHealth usage was more intensive (greater than the mean). Users with long-term health problems or illnesses (OR 1.20, 95% CI 1.12-1.29) or receiving long-term treatment (OR 1.11, 95% CI 1.03-1.20), having family members with long-term health problems or illnesses (OR 1.44, 95% CI 1.34-1.55), or undertaking care activities for other people (OR 1.58, 95% CI 1.40-1.77) had a high propensity toward intensive eHealth usage. Sociodemographic predictors showed that Internet users who were female (OR 1.23, 95% CI 1.14-1.31), aged 25-54 years (OR 1.12, 95% CI 1.05-1.21), living in larger households (3 members: OR 1.25, 95% CI 1.15-1.36; 5 members: OR 1.13, 95% CI 0.97-1.28; ≥6 members: OR 1.31, 95% CI 1.10-1.57), had more children 65 years of age (1 member: OR 1.33, 95% CI 1.18-1.50; ≥4 members: OR 1.82, 95% CI 0.54-6.03) had a greater propensity toward intensive eHealth usage. Likewise, users residing in densely populated areas, such as cities and large towns (OR 1.17, 95% CI 1.09-1.25), also had a greater propensity

    Objective Internet has become an important source of information for cancer patients regarding disease and treatment. A national survey was conducted to assess the importance of Internet in the routine care of cancer patients in Germany. Method The cross-sectional survey included 5,984 outpatients (56.7% female, M=64.3 years, SD=12). 3 groups were identified: Internet users, non-users whose families/friends did online research for them, and "complete" non-users. The data was analyzed using descriptive statistics and group comparisons. Results 1 patient in 2 used the Internet to research health-related information. Internet users considered this research to be helpful, felt better able to participate in health-related decisions, and less alone with their disease. However, the information found online contributed to a feeling of uncertainty. 72.5% of Internet users researched treatment options and 21.3% talked to their doctor about their research. Conclusion The Internet was shown to be an important source of information for cancer patients. For patients to be able to use Internet research meaningfully, it could be helpful that they receive support from their oncologist. © Georg Thieme Verlag KG Stuttgart · New York.

    In the last decade we have observed a considerable increase in nonmedical usage of dextromethorphan (DXM) among young age groups, especially school children between 13 and 16 yrs. We analysed the "trip reports" after use of DXM, available on a website: www.hyperreal.info in the years 1999-2013. The data collected by authors were analysed according to: age, sex, symptoms, dose of DXM, a reason and a place of using the drug. A review of 124 "trip reports" showed that the majority of their writers are male (M 90.3%, F 9.7%). Young people, aged 16-20 (80.4%), dominated among the study population. The most common place of using DXM was a flat of a drug user (70.2%), and the reason of using a willingness to experiment with new psychoactive substances (41.9%) as well as the desire of "get high" (25.8%). The majority of users used DXM at least once again in their lives (56.5%). A single dose of the ingested drug ranged from 120 mg to 1575 mg (mean 539.25 mg). Most often received doses were 450 mg (30.4%), 300 mg (12%), 900 mg (11.2%). DXM was positively assessed by the internauts as a recreational psychoactive substance (84.7%). The most common clinical symptoms described by internauts were: difficulties with walking (74.2%), visual illusions (73.4%), altered sense of time (41.9%), feeling of exteriorisation (35.5%), euphoria (33.1%), nausea and vomiting (32.3%), auditory illusions (30.6%) and pruritus (29.8%). 1. DXM is the popular psychoactive substance which has gained a positive opinion among the Internet users. 2. Easy accessibility of DXM may pose a serious threat to health of young people who experiment with psychoactive substances. 3. The improvement of DXM sales control should be considered.

    Gaie, Martha J

    2006-01-01

    This paper presents an evolving user-oriented model of Internet health information seeking (IS) based on qualitative data collected from 22 lung cancer (LC) patients and caregivers. This evolving model represents information search behavior as more highly individualized, complex, and dynamic than previous models, including pre-search psychological activity, use of multiple heuristics throughout the process, and cost-benefit evaluation of search results. This study's findings suggest that IS occurs in four distinct phases: search initiation/continuation, selective exposure, message processing, and message evaluation. The identification of these phases and the heuristics used within them suggests a higher order of complexity in the decision-making processes that underlie IS, which could lead to the development of a conceptual framework that more closely reflects the complex nature of contextualized IS. It also illustrates the advantages of using qualitative methods to extract more subtle details of the IS process and fill in the gaps in existing models.

    The Internet is an important tool in assisting the older population to lead independent and social lives. However, the majority of Internet users are under 55. This study investigated the following psychological barriers to Internet use by older adults: perceived usefulness, perceived ease of use, Internet efficacy, perceived complexity of navigation and perceived complexity of terminology. Twenty-three subjects (aged 55 - 75 years) were interviewed in the UK. The influences of age, computer and Internet experience, and training on these psychological barriers were explored. The results showed that the majority of the older adults who had a positive perception of usefulness, ease of use, and efficacy of the Internet or e-mail, used the Internet or e-mail more often. In addition, it was found that computer or Internet experience increased perceptions of ease of use and efficacy of the Internet and reduced perceived complexity of navigation. There was no difference between the two age groups (55 - 65 and 66 - 75 years) in these psychological barriers. It was concluded that increased marketing of the Internet (aimed at the older user), more simple and uniformly designed Internet pages, more user-friendly online help and error message terminology, and increased provision of training for the older user would assist uptake of the World Wide Web.

    As the number of internet users increases, a new game genre using the internet as a networking tool is emerging. Some game genres are regarded as having greater addiction potentials than others. Games and the internet are closely related. We investigated games frequently used by adolescents and classified each of them with the help of game professionals. We also examined internet use patterns to identify relationships between game genre and internet use patterns. 627 middle school and high school students (male 488, female 139) completed questionnaires concerning computer and game use patterns and Korean internet addiction scales. Game genres were divided into eight criteria (simulation, role playing game, web board, community, action, adventure, shooting, and sports). Using Korean internet addiction scales, 627 participants were divided into a normal group (474), a potential risk group (128), and a high-risk group (25). Each group showed significant differences in total internet addiction scores. We classified players into specific game users based upon the game types they most prefer. Role playing game users showed significantly higher internet addiction scores than web board and sports game users. Game and internet addictions are also connected with interpersonal relationship patterns. We suggest that users of some game genre have unique psychological addiction potentials that are different from others and that this influences both game selection and internet use.

    Internet use is nearly ubiquitous among adolescents. Growing evidence suggests heavy Internet use negatively impacts health, yet the relationship between time spent on the Internet and adolescent blood pressure (BP) is unknown. We examined the association between Internet use and elevated BP in a racially diverse cross-sectional sample of 331 healthy adolescents (ages 14-17 years). Heavy Internet use was defined as ≥ 2 hr/day, moderate use as Internet users had statistically significantly higher odds of elevated BP compared to light Internet users. School nurses can play an important role in preventing high BP through assessment of BP and other health behaviors including Internet use, and health teaching to individuals, student groups, faculty, and parents to increase awareness of the relationship between Internet use and health. © The Author(s) 2014.

    The core of the computer program STRMDEPL08 that estimates streamflow depletion by a pumping well with one of four analytical solutions was re-written in the Javascript software language and made available through an internet-based interface (web page). In the internet-based interface, the user enters data for one of the four analytical solutions, Glover and Balmer (1954), Hantush (1965), Hunt (1999), and Hunt (2003), and the solution is run for constant pumping for a desired number of simulation days. Results are returned in tabular form to the user. For intermittent pumping, the interface allows the user to request that the header information for an input file for the stand-alone executable STRMDEPL08 be created. The user would add the pumping information to this header information and run the STRMDEPL08 executable that is available for download through the U.S. Geological Survey. Results for the internet-based and stand-alone versions of STRMDEPL08 are shown to match.

    2015-08-01

    The popularity of online recreational activities, such as social networking, has dramatically increased the amount of time spent on the Internet. Excessive or inappropriate use of the Internet can result in serious adverse consequences. The current study used a behavioral economic task to determine if the amount of time spent online by problematic and nonproblematic users can be modified by price. The Internet Purchase Task was used to determine how much time undergraduate students (N=233) would spend online at 13 different prices. Despite high demand for Internet access when access was free, time spent online by both problematic and nonproblematic users decreased dramatically, even at low prices. These results suggest that the amount of time spent online may be modified by having a tangible cost associated with use, whereas having free access to the Internet may encourage excessive, problematic use.

    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.

    Background Previous studies have identified socioeconomic status and health status as predictors of older adults’ computer and Internet use, but researchers have not examined the relationships between older adults’ health needs and psychological capital (emotional well-being and self-efficacy) and social capital (social integration/ties and support networks) to different types of Internet use. Objective This study examined (1) whether older adults’ health conditions and psychological and social capital differentiate Internet users from nonusers, and (2) whether the Internet users differed in their types of Internet use on the basis of their health conditions and psychological and social capital. Methods Data for this study came from the National Health and Aging Trends Study, which is based on a nationally representative sample of US Medicare beneficiaries aged 65 years and older. The sample for this study were those who resided in the community in their own or others’ homes (N=6680). Binary logistic regression analysis was used to compare health needs, psychological capital, and social capital among (1) any type of Internet users and nonusers, (2) Internet users who engaged in health-related tasks and Internet users who did not, (3) Internet users who engaged in shopping/banking tasks and Internet users who did not, and (4) Internet users only used the Internet for email/texting and all other Internet users. Results Depressive and anxiety symptoms, measures of psychological capital, were negatively associated with Internet use among older adults (odds ratio [OR] 0.83, 95% CI 0.70-0.98, P=.03 and OR 0.79, 95% CI 0.65-0.97, P=.03, respectively), whereas most measures of social capital were positively associated with Internet use. Having more chronic medical conditions and engaging in formal volunteering increased the odds of Internet use for health-related tasks by 1.15 (95% CI 1.08-1.23, PInternet use for shopping/banking activities (OR 0.75, 95% CI 0

    The Internet hosts an abundance of science video resources aimed at communicating scientific knowledge, including webinars, massive open online courses, and TED talks. Although these videos are efficient at disseminating information for diverse types of users, they often do not demonstrate the process of doing science, the excitement of scientific discovery, or how new scientific knowledge is developed. iBiology (www.ibiology.org), a project that creates open-access science videos about biology research and science-related topics, seeks to fill this need by producing videos by science leaders that make their ideas, stories, and experiences available to anyone with an Internet connection. © 2014 Goodwin.

  11. Developing a user-friendly photometric software for exoplanets to increase participation in Citizen Science

    2017-09-01

    Previous research on Citizen Science projects agree that Citizen Science (CS) would serve as a way of both increasing levels of public understanding of science and public participation in scientific research. Historically, the concept of CS is not new, it dates back to the 20th century when citizens where making skilled observations, particularly in archaeology, ecology, and astronomy. Recently, the idea of CS has been improved due to technological progress and the arrival of Internet. The phrase "astronomy from the chair" that is being used in the literature highlights the extent of the convenience for analysing observational data. Citizen science benefits a variety of communities, such as scientific researchers, volunteers and STEM educators. Participating in CS projects is not only engaging the volunteers with the research goals of a science team, but is also helping them learning more about specialised scientific topics. In the case of astronomy, typical examples of CS projects are gathering observational data or/and analysing them. The Holomon Photometric Software (HOPS) is a user-friendly photometric software for exoplanets, with graphical representations, statistics, models, options are brought together into a single package. It was originally developed to analyse observations of transiting exoplanets obtained from the Holomon Astronomical Station of the Aristotle University of Thessaloniki. Here, we make the case that this software can be used as part of a CS project in analysing transiting exoplanets and producing light-curves. HOPS could contribute to the scientific data analysis but it could be used also as an educational tool for learning and visualizing photometry analyses of transiting exoplanets. Such a tool could be proven very efficient in the context of public participation in the research. In recent successful representative examples such as Galaxy Zoo professional astronomers cooperating with CS discovered a group of rare galaxies by using

    The Internet provides inexpensive, interesting and comfortable recreation, but sometimes users get hooked. Thus, the computer-internet addiction concept has been proposed as an explanation for uncontrollable and damaging use. Symptoms of addiction could be compared to other addictive behaviors such as pathological gambling, kleptomania, trichotillomania, sex addiction and pyromania. Although criteria to diagnose this addiction have been proposed, methods of assessing excessive computer-internet use are limited. Early diagnosis could help the patient that suffers from this addiction before developing additional psychiatric diagnoses. A review of the proposed etiologies in the literature is summarized, together with recommendations for physicians and mental health officials.

  14. Extending eScience Provenance with User-Submitted Semantic Annotations

    eScience based systems generate provenance of their data products, related to such things as: data processing, data collection conditions, expert evaluation, and data product quality. Recent advances in web-based technology offer users the possibility of making annotations to both data products and steps in accompanying provenance traces, thereby expanding the utility of such provenance for others. These contributing users may have varying backgrounds, ranging from system experts to outside domain experts to citizen scientists. Furthermore, such users may wish to make varying types of annotations - ranging from documenting the purpose of a provenance step to raising concerns about the quality of data dependencies. Semantic Web technologies allow for such kinds of rich annotations to be made to provenance through the use of ontology vocabularies for (i) organizing provenance, and (ii) organizing user/annotation classifications. Furthermore, through Linked Data practices, Semantic linkages may be made from provenance steps to external data of interest. A desire for Semantically-annotated provenance has been motivated by data management issues in the Mauna Loa Solar Observatory’s (MLSO) Advanced Coronal Observing System (ACOS). In ACOS, photomoeter-based readings are taken of solar activity and subsequently processed into final data products consumable by end users. At intermediate stages of ACOS processing, factors such as evaluations by human experts and weather conditions are logged, which could impact data product quality. If such factors are linked via user-submitted annotations to provenance, it could be significantly beneficial for other users. Likewise, the background of a user could impact the credibility of their annotations. For example, an annotation made by a citizen scientist describing the purpose of a provenance step may not be as reliable as a similar annotation made by an ACOS project member. For this work, we have developed a software package that

    Borne, K. D.

    2009-12-01

    The emergence of e-Science over the past decade as a paradigm for Internet-based science was an inevitable evolution of science that built upon the web protocols and access patterns that were prevalent at that time, including Web Services, XML-based information exchange, machine-to-machine communication, service registries, the Grid, and distributed data. We now see a major shift in web behavior patterns to social networks, user-provided content (e.g., tags and annotations), ubiquitous devices, user-centric experiences, and user-led activities. The inevitable accrual of these social networking patterns and protocols by scientists and science projects leads to U-Science as a new paradigm for online scientific research (i.e., ubiquitous, user-led, untethered, You-centered science). U-Science applications include components from semantic e-science (ontologies, taxonomies, folksonomies, tagging, annotations, and classification systems), which is much more than Web 2.0-based science (Wikis, blogs, and online environments like Second Life). Among the best examples of U-Science are Citizen Science projects, including Galaxy Zoo, Stardust@Home, Project Budburst, Volksdata, CoCoRaHS (the Community Collaborative Rain, Hail and Snow network), and projects utilizing Volunteer Geographic Information (VGI). There are also scientist-led projects for scientists that engage a wider community in building knowledge through user-provided content. Among the semantic-based U-Science projects for scientists are those that specifically enable user-based annotation of scientific results in databases. These include the Heliophysics Knowledgebase, BioDAS, WikiProteins, The Entity Describer, and eventually AstroDAS. Such collaborative tagging of scientific data addresses several petascale data challenges for scientists: how to find the most relevant data, how to reuse those data, how to integrate data from multiple sources, how to mine and discover new knowledge in large databases, how to

    To examine the relationship between different Internet-use intensities and adolescent mental and somatic health. Data were drawn from the 2002 Swiss Multicenter Adolescent Survey on Health, a nationally representative survey of adolescents aged 16 to 20 years in post-mandatory school. From a self-administered anonymous questionnaire, 3906 adolescent boys and 3305 girls were categorized into 4 groups according to their intensity of Internet use: heavy Internet users (HIUs; >2 hours/day), regular Internet users (RIUs; several days per week and ≤ 2 hours/day), occasional users (≤ 1 hour/week), and non-Internet users (NIUs; no use in the previous month). Health factors examined were perceived health, depression, overweight, headaches and back pain, and insufficient sleep. In controlled multivariate analysis, using RIUs as a reference, HIUs of both genders were more likely to report higher depressive scores, whereas only male users were found at increased risk of overweight and female users at increased risk of insufficient sleep. Male NIUs and female NIUs and occasional users also were found at increased risk of higher depressive scores. Back-pain complaints were found predominantly among male NIUs. Our study provides evidence of a U-shaped relationship between intensity of Internet use and poorer mental health of adolescents. In addition, HIUs were confirmed at increased risk for somatic health problems. Thus, health professionals should be on the alert when caring for adolescents who report either heavy Internet use or very little/none. Also, they should consider regular Internet use as a normative behavior without major health consequence.

    Full Text Available The article aims to describe who is the internet user in Brazil, based on a national sample survey with 18,000 respondents in 2014. It’s possible to identify specific nuances and characteristics of internet users by individual socio-economic characteristics, such as income, age, education, and also macro-social features, such as the region of the country where the user lives. The hypothesis is that similarly to what happens in other countries, the economic limits are no longer significant barriers for not using the internet. Those who do not use the internet do so by choice and not by economic limitations. The differences would be explained by other characteristics, such as education and age. To test the hypothesis we have built the Internet Centrality Index and we have compared the socioeconomic and the geographic profiles by the position in the index. The results show a partial shift from TV to the internet.

    Individuals with schizophrenia spectrum disorders use the Internet for general and health-related purposes. Their ability to find, understand, and apply the health information they acquire online in order to make appropriate health decisions - known as eHealth literacy - has never been investigated. The European agenda strives to limit health inequalities and enhance mental health literacy. Nevertheless, each European member state varies in levels of Internet use and online health information-seeking. This study aimed to examine computer/Internet use for general and health-related purposes, eHealth literacy, and attitudes toward computer/Internet among adults with schizophrenia spectrum disorders from two distant European regions. Data were collected from mental health services of psychiatric clinics in Finland (FI) and Greece (GR). A total of 229 patients (FI = 128, GR = 101) participated in the questionnaire survey. The data analysis included evaluation of frequencies and group comparisons with multiple linear and logistic regression models. The majority of Finnish participants were current Internet users (FI = 111, 87%, vs. GR = 33, 33%, P eHealth literacy of Internet users (previous and current Internet users) was found significantly higher in the Finnish group (FI: Mean = 27.05, SD 5.36; GR: Mean = 23.15, SD = 7.23, P eHealth literacy and Interest. The Finnish group of Internet users scored higher in eHealth literacy, while the Greek group of never Internet users had a higher Interest in computer/Internet. eHealth literacy is either moderate (Finnish group) or low (Greek group). Thus, exposure to ICT and eHealth skills training are needed for this population. Recommendations to improve the eHealth literacy and access to health information among these individuals are provided.

    The Internet is increasingly used to deliver treatment programs for common mental disorders. However, little is known about the acceptability of online interventions. The present study used an online survey to explore levels of acceptability of Internet-based treatment programs for anxiety and depression. Visitors to websites operated by the Clinical Research Unit for Anxiety and Depression (CRUfAD), were invited to complete an online questionnaire during 16 weeks in 2008. Of 1543 people who began the survey, 1104 (72%) Australian health professionals and lay people completed it. Internet treatment programs for people with mild or moderate symptoms were more acceptable than programs for people with severe symptoms. There were no differences between health professionals and non-health professionals in acceptability ratings. As expected, previous users of Internet treatments reported significantly greater acceptability and preference for Internet treatments than non-users. Respondents rated Internet-based treatment programs as acceptable, with higher ratings from previous users. In order to facilitate implementation, program developers need to implement strategies for increasing knowledge about the efficacy and effectiveness of such programs, and engage therapists and consumers in establishing ethical and professional guidelines for their safe and responsible use.

    This study examined the prevalence and characteristics of New Jersey adults who reported seeing tobacco products advertised on the Internet and described the means by which these products were advertised. Data were analyzed from the New Jersey Adult Tobacco Survey (NJATS), a repeated, cross-sectional, random-digit-dial telephone survey conducted with a statewide representative sample. We used logistic regression to determine factors associated with recall of tobacco Internet advertising, adjusting for demographics, smoking behavior variables, and receipt of tobacco industry direct mail. Participants included 3,930 adults who completed the 2001 NJATS, 4,004 adults who completed the 2002 survey, and 3,062 adults who completed the 2005 survey. The proportion of adult Internet users reporting exposure to tobacco product advertising on the Internet has increased each year (6.9% in 2001, 15.6% in 2002, 17.8% in 2005). Based on 2005 data, recall of tobacco product advertising on the Internet was higher among males young adults aged 18-24 years, Asians, adults who reported receipt of direct mail advertising, and adults with a postcollege education. In addition, adult Internet users most often reported seeing tobacco products advertised on the Internet via pop-up or banner ads (60.7%), followed by E-mail messages (24.6%), and Web sites (14.9%). Recall of tobacco advertising by Internet users increased between 2001 and 2005 and was particularly high among certain subgroups. An urgent need exists for expanded surveillance of Internet tobacco sales and marketing practices.

  5. Internet-based instruction in college teaching

    Flickinger, Kathleen Anne

    Distance education and Internet instruction are increasingly being used in college science teaching. In an effort to reach more students, Iowa State University's Human Anatomy and Physiology course was offered via Internet as well as via traditional lecture format. To assess the educational ramifications of this offering, three studies were conducted. In the first study, a collective case study approach was utilized to describe the learning environment created by an Internet-based college science course. In this study, three students were followed as they worked their way through the course. Collective case study methodologies were used to provide a rich description of the learning environment experienced by these students. Motivation, computer savvy, and academic and personal self-confidence appeared to impact the satisfaction level of the students enrolled in the class. To evaluate the effectiveness of the learning environment offered through the Internet-based science course, a quantitative comparison study was undertaken. In this study a comparison of achievement scores and study habits between students enrolled in the Internet-based class and those enrolled in the traditional section was made. Results from this study indicated that content understanding and retention did not appear to be effected by the type of instruction. Desirable study habits were reportedly used more frequently in the Internet section of the class than in the traditional class. To complete the description of the Internet course experience, a qualitative examination of Internet instructors' time commitment and level of teaching satisfaction was conducted. Data for this study consisted of interviews and researcher observations. Instructor time-on-task was initially quite high, and remained above the average spent on average face-to-face instruction in subsequent semesters. Additionally the role of the faculty member changed dramatically, causing some lessening of job satisfaction. Taken as

    To examine experiences among individuals in the USA with traumatic brain injury (TBI) regarding their access to and use of the Internet, problems encountered, and desire for improved Internet access and skills. An in-depth survey was administered as a semi-structured interview to 80 individuals at least 3 months post moderate to severe TBI. Two-thirds of respondents reported having a computer at home, but only half had access to the Internet. Fewer than half were Internet users, as compared to 60% users in the USA population at the time of the survey. However, Internet activities engaged in by users in this sample were comparable to those of the overall population. There was a strong interest in using the Internet among non-users. Most respondents expressed a strong desire for coaching or other training to enhance or develop Internet skills. Reported reasons for Internet non-use in this sample were lack of access and knowledge, versus lack of interest as in the general population. The high interest in using and learning more about the Internet supports the development of interventions to mprove Internet skills for people with TBI.

    Purpose: Studies describing the use of the Internet by radiation oncology patients are lacking. This multi-institutional study of cancer patients presenting to academic (AC), community (CO) and veterans (VA) radiation oncology centers was designed to analyze the use of the Internet, predictive factors for utilization, and barriers to access to the Internet. Materials and Methods: A questionnaire evaluating the use of the Internet was administered to 921 consecutive patients presenting to radiation oncology departments at AC, CO and VA Medical Centers. The study included 436 AC patients (47%), 284 CO patients (31%), and 201 VA patients (22%). A computer was available at home to 427 patients (46%) and 337 patients (37%) had Email access. The mean age of the patient population was 64 years (range=14-93). Males represented 70% of the patient population. The most common diagnoses included prostate cancer (33%), breast cancer (13%), and lung cancer (11%). Results: Overall, 265/921 patients (29%) were using the Internet to find cancer related information. The Internet was used by 42% of AC patients, 25% of CO patients and only 5% of VA patients (p<.0001). A computer was available at home in 62% AC vs. 45% CO vs. 12% VA patients (p<.0001). Patients < 60 years were much more likely to use the Internet than older patients (p<.0001). Most of the Internet users considered the information either very reliable (22%) or somewhat reliable (70%). Most patients were looking for information regarding treatment of their cancer (90%), management of side effects of treatment (74%), alternative/complementary treatments (65%) and clinical trials (51%). Unconventional medical therapies were purchased over the Internet by 12% of computer users. Products or services for the treatment or management of cancer were purchased online by 12% of Internet users. Conclusion: A significant number of cancer patients seen in radiation oncology departments at academic and community medical centers

Intelligent Agents are executable software components that represent the user, perform tasks on behalf of the user and when the task terminates, the Agents send the result to the user. Intelligent Agents are best suited for the Internet: a collection of computers connected together in a world-wide computer network. Swarm and HYDRA computer architectures for Agents’ execution were developed at the University of Surrey, UK in the 90s. The objective of the research was to develop a software-based computer architecture on which Agents execution could be explored. The combination of Intelligent Agents and HYDRA computer architecture gave rise to a new computer concept: the NET-Computer in which the comput­ing resources reside on the Internet. The Internet computers form the hardware and software resources, and the user is provided with a simple interface to access the Internet and run user tasks. The Agents autonomously roam the Internet (NET-Computer executing the tasks. A growing segment of the Internet is E-Commerce for online shopping for products and services. The Internet computing resources provide a marketplace for product suppliers and consumers alike. Consumers are looking for suppliers selling products and services, while suppliers are looking for buyers. Searching the vast amount of information available on the Internet causes a great deal of problems for both consumers and suppliers. Intelligent Agents executing on the NET-Computer can surf through the Internet and select specific information of interest to the user. The simulation results show that Intelligent Agents executing HYDRA computer architecture could be applied in E-Commerce.

    Abstract As Internet use grows, so do the benefits and also the risks. Thus, it is important to identify when individuals' Internet use is problematic. In the present study, 449 participants aged from 16 to 71 years of age were sourced from a wide range of English-speaking Internet forums, including social media and self-help groups. Of these, 68.9% were classified as nonproblematic users, 24.4% as problematic users, and 6.7% as addictive Internet users. High use of discussion forums, high rumination levels, and low levels of self-care were the main contributing factors to Internet addiction (IA) among adolescents. For adults IA was mainly predicted through engagement in online video gaming and sexual activity, low email use, as well as high anxiety and high avoidant coping. Problematic Internet users scored higher on emotion and avoidance coping responses in adults and higher on rumination and lower on self-care in adolescents. Avoidance coping responses mediated the relationship between psychological distress and IA. These findings may assist clinicians with designing interventions to target different factors associated with IA. PMID:28414517

    The Science Gateway Institute (SGW-I) for the Democratization and Acceleration of Science was a SI2-SSE Collaborative Research conceptualization award funded by NSF in 2012. From 2012 through 2015, we engaged interested members of the science and engineering community in a planning process for a Science Gateway Community Institute (SGCI). Science Gateways provide Web interfaces to some of the most sophisticated cyberinfrastructure resources. They interact with remotely executing science applications on supercomputers, they connect to remote scientific data collections, instruments and sensor streams, and support large collaborations. Gateways allow scientists to concentrate on the most challenging science problems while underlying components such as computing architectures and interfaces to data collection changes. The goal of our institute was to provide coordinating activities across the National Science Foundation, eventually providing services more broadly to projects funded by other agencies. SGW-I has succeeded in identifying two underrepresented communities of future gateway designers and users. The Association of Computer and Information Science/Engineering Departments at Minority Institutions (ADMI) was identified as a source of future gateway designers. The National Organization for the Professional Advancement of Black Chemists and Chemical Engineers (NOBCChE) was identified as a community of future science gateway users. SGW-I efforts to engage NOBCChE and ADMI faculty and students in SGW-I are now woven into the workforce development component of SGCI. SGCI (ScienceGateways.org ) is a collaboration of six universities, led by San Diego Supercomputer Center. The workforce development component is led by Elizabeth City State University (ECSU). ECSU efforts focus is on: Produce a model of engagement; Integration of research into education; and Mentoring of students while aggressively addressing diversity.

    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.

    Internet-based technologies such as personal health records and patient portals are increasingly viewed as essential for enhancing patient-provider communication and patient-centered care. We examined how primary care patients use the Internet, particularly patient characteristics associated with Internet use. We surveyed patients in five primary care clinic waiting rooms. Patients who had used email or the Internet in the past month (Internet users) were asked how often they used a computer for a variety of tasks. Participants who reported not using the Internet were asked about several potential barriers to Internet use. We approached 713 patients, and 638 (89.6%) completed questionnaires; 499 (78%) were Internet users and 139 (22%) were non-users. Lack of computer access and not knowing how to use email or the Internet were the most common barriers to Internet use. Younger age, higher education and income, better health, and absence of a chronic illness were associated with Internet use. After controlling for age and other variables, chronic illness was no longer associated with Internet use. Internet use was high among our primary care patients. The major factor associated with Internet use among patients with chronic conditions was their age. If older adults with chronic illness are to reap the benefits of health information technology, their Internet access will need to be improved. Institutions that are planning to offer consumer health information technology should be aware of groups with lower Internet access.

    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.

    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 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.

    In this study, the assessment tool "Internet and Computer User Profile" questionnaire (ICUP) is presented and validated. It was developed in order to gather information for setting intervention goals to meet current demands. Sixty-eight subjects aged 23-68 participated in the study. The study group (n = 28) was sampled from two vocational centers. The control group consisted of 40 participants from the general population that were sampled by convenience sampling based on the demographics of the study group. Subjects from both groups answered the ICUP questionnaire. Subjects of the study group answered the General Self- Efficacy (GSE) questionnaire and performed the Assessment of Computer Task Performance (ACTP) test in order to examine the convergent validity of the ICUP. Twenty subjects from both groups retook the ICUP questionnaire in order to obtain test-retest results. Differences between groups were tested using multiple analysis of variance (MANOVA) tests. Pearson and Spearman's tests were used for calculating correlations. Cronbach's alpha coefficient and k equivalent were used to assess internal consistency. The results indicate that the questionnaire is valid and reliable. They emphasize that the layout of the ICUP items facilitates in making a comprehensive examination of the client's perception regarding his participation in computer and internet activities. Implications for Rehabiliation The assessment tool "Internet and Computer User Profile" (ICUP) questionnaire is a novel assessment tool that evaluates operative use and individual perception of computer activities. The questionnaire is valid and reliable for use with participants of vocational centers dealing with mental illness. It is essential to facilitate access to computers for people with mental illnesses, seeing that they express similar interest in computers and internet as people from the general population of the same age. Early intervention will be particularly effective for young

    Full Text Available Broad ad targeting options belong among the major advantages of internet advertising. Demographic targeting has become a standard option in most of on-line advertising systems. There are more ways how to target on-line advertisements by using demographic variables. In some cases, e.g., social media, we can use data from user registrations. Modern technologies enable to estimate the demographic profile of internet users using on behavioural data. The traditional approach to the demographic targeting of advertisements based on affinity targeting assumes the existence of internet servers with sufficient homogeneity of visits. The aim of this article is to identify the differences in the internet content consumption habits of Czech internet users based on gender and age. The analysis is based on the data from the extensive research which was carried out by the Netmonitor project, and which was provided for the purposes of this study by the Association for Internet Development (SPIR. The research results show that the traditional affinity-based method of targeting according to gender and age is still suitable on the Czech internet. On the other hand, in some cases, the traditional approach of ad targeting based on affinity leads to wasted ad impressions that miss defined target group.

    In spite of the Internet's phenomenal growth and social impact, many aspects of the collective communication behavior of its users are largely unknown. Understanding the structure and dynamics of the behavioral networks that connect users with each other and with services across the Internet is key to modeling the network and designing future applications. We present a characterization of the properties of the behavioral networks generated by several million users of the Abilene (Internet2) network. Structural features of these networks offer new insights into scaling properties of network activity and ways of distinguishing particular patterns of traffic. For example, we find that the structure of the behavioral network associated with Web activity is characterized by such extreme heterogeneity as to challenge any simple attempt to model Web server traffic

    In spite of the Internet's phenomenal growth and social impact, many aspects of the collective communication behavior of its users are largely unknown. Understanding the structure and dynamics of the behavioral networks that connect users with each other and with services across the Internet is key to modeling the network and designing future applications. We present a characterization of the properties of the behavioral networks generated by several million users of the Abilene (Internet2) network.

    Although playing of Internet games may lead to Internet gaming disorder (IGD), most game-users do not develop problems and only a relatively small subset experiences IGD. Game playing may have positive health associations, whereas IGD has been repeatedly associated with negative health measures, and it is thus important to understand differences between individuals with IGD, recreational (non-problematic) game use (RGU) and non-/low-frequency game use (NLFGU). Individuals with IGD have shown differences in neural activations from non-gamers, yet few studies have examined neural differences between individuals with IGD, RGU and NLFGU. Eighteen individuals with IGD, 21 with RGU and 19 with NFLGU performed a color-word Stroop task and a guessing task assessing reward/loss processing. Behavioral and functional imaging data were collected and compared between groups. RGU and NLFGU subjects showed lower Stroop effects as compared with those with IGD. RGU subjects as compared to those with IGD demonstrated less frontal cortical activation brain activation during Stroop performance. During the guessing task, RGU subjects showed greater cortico-striatal activations than IGD subjects during processing of winning outcomes and greater frontal brain during processing of losing outcomes. Findings suggest that RGU as compared with IGD subjects show greater executive control and greater activations of brain regions implicated in motivational processes during reward processing and greater cortical activations during loss processing. These findings suggest neural and behavioral features distinguishing RGU from IGD and mechanisms by which RGU may be motivated to play online games frequently yet avoid developing IGD.

    2015-07-01

    Full Text Available As the trend of ICT (Information and Communication Technology development is gaining larger influence over countries’ development and growth, Internet banking plays an important role in enhancing the growth of several developed and developing economies over the 21th century. Internet banking and other electronic payment systems are relatively new in Romania and is expected to result in a more efficient banking system. However, in this study we try to argue the fact that Internet banking is strategically important to the banking sectors in an emerging economy, such as Romania, by means of statistical-econometric methodology. For this I used statistical data from Eurostat and MSI for the period 2009-2013. I proposed two models to highlight the existence of a relationship between the variables. The results of the first model have pointed out the fact that the rise of number of Internet users leads to an increase of the number of Internet banking users. The results of the second model show how the indicators influence Internet Banking users and the number of transactions made by Internet Banking influences the value of transactions made by Internet Banking.

    2013-02-01

    Full Text Available Removing illegal or harmful material from the internet has been pursued for more than two decades. The advent of Web 2.0, with the prominent increase and diffusion of user-generated content, amplifies the necessity for technical and legal frameworks enabling the removal of illegal material from the network. This study deals with different levels and methods of Internet ‘cleansing’ measures, comparing government regulated and Internet service provider based removals of illegal Internet content. The paper aims at putting the regulatory option of internet blocking measures into the broader perspective of the legal framework regulating the (exemption from liability of Intermediary Service Providers (ISPs for user-generated contents. In addition, the paper suggests proposals on which regulatory options can better ensure the respect of freedoms and the protection of rights. The paper introduces several significant cases of blocking online copyright infringing materials. Copyright related blocking techniques have been devised for business reasons – by copyright holders’ associations. It must be recalled, however, that these blocking actions cannot be enforced without the states’ intervention. These business-level actions become isolated if they are not supported by both the European Union and its Member States. Conversely, state-centred initiatives cannot work out without the private sector’s cooperation. Internet service providers play a crucial role in this cooperative framework because of their task of providing access to the Internet and hosting web contents.

    2013-02-01

    The growing role of Internet in all aspects of everyday life has led to speculations over the impacts beyond the traditional questions of access or sociability. This in mind, the main focus in this article was to examine how Finns, for majority of whom Internet use has become commonplace activity, perceive the impacts of Internet use since first adopting the technology. In this study, we examine how Internet user history and perceived computer skills, along with different sociodemographic factors, appear to reflect on the perceived impacts of Internet adoption in terms of memory and ability to concentrate. According to the results, almost one in five of the respondents reported changes concerning their memory or ability to concentrate, with skilled computer users and nonworkers, in particular, perceiving the change. Factors such as age-related differences and exposure to potential information overload at work were identified to explain the perceived change. Our data were collected in a survey-gathering information on the everyday life and well-being of Finns. The sample consisted of 2000 Finnish speakers aged 15 to 64 years. The response rate was 46 percent (N=908).

    2010-07-01

    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.

  17. Security incidents on the Internet, 1989--1995

    Energy Technology Data Exchange (ETDEWEB)

    Howard, J.D.

    1995-12-31

    This paper presents an analysis of trends in Internet security based on an investigation of 4,299 Internet security-related incidents reported to the CERT{reg_sign} Coordination Center (CERT{reg_sign}/CC) from 1989 through 1995. Prior to this research, knowledge of actual Internet security incidents was limited and primarily anecdotal. This research: (1) developed a taxonomy to classify Internet attacks and incidents, (2) organized, classified, and analyzed CERT{reg_sign}/CC incident records, (3) summarized the relative frequency of the use of tools and vulnerabilities, success in achieving access, and results of attacks, (4) estimated total Internet incident activity, (5) developed recommendations for Internet users and suppliers, and (6) developed recommendations for future research. With the exception of denial-of-service attacks, security incidents were found to be increasing at a rate less than Internet growth. Estimates showed that most, if not all, severe incidents were reported to the CERT{reg_sign}/CC, and that more than one out of three above average incidents (in terms of duration and number of sites) were reported. Estimates also indicated that a typical Internet site was involved in, at most, around one incident (of any kind) per year, and a typical Internet host in, at most, around one incident in 45 years. The probability of unauthorized privileged access was around an order of magnitude less likely. As a result, simple and reasonable security precautions should be sufficient for most Internet users.

    Wang, Dongyan; Lin, Bo; Zhang, Jun

    1998-12-01

    In this paper, we present JIP - Java Image Processing on the Internet, a new Internet based application for remote education and software presentation. JIP offers an integrate learning environment on the Internet where remote users not only can share static HTML documents and lectures notes, but also can run and reuse dynamic distributed software components, without having the source code or any extra work of software compilation, installation and configuration. By implementing a platform-independent distributed computational model, local computational resources are consumed instead of the resources on a central server. As an extended Java applet, JIP allows users to selected local image files on their computers or specify any image on the Internet using an URL as input. Multimedia lectures such as streaming video/audio and digital images are integrated into JIP and intelligently associated with specific image processing functions. Watching demonstrations an practicing the functions with user-selected input data dramatically encourages leaning interest, while promoting the understanding of image processing theory. The JIP framework can be easily applied to other subjects in education or software presentation, such as digital signal processing, business, mathematics, physics, or other areas such as employee training and charged software consumption.

    Internet addiction has been typically conceptualized as either a continuous construct or a dichotomous construct. Limited research has differentiated adolescents with problematic Internet use (PIU) from the Internet addiction group (IA) and/or nonproblematic Internet use group (NPIU) and examined the potential correlates. To fill this gap, based on data obtained from 956 Chinese adolescents (11-19 years, 47% male), this study examined if adolescents with PIU is a distinctive group from the IA and NPIU. This study also examined factors from different ecological levels that may differentiate among the three groups, including individual, parental, peer, and sociodemographic factors. Results indicated that IA, PIU, and NPIU differed significantly on scores of Young's Diagnostic Questionnaire (YDQ). Critical factors emerging from different ecological levels could differentiate between PIU and NPIU and between IA and NPIU. Such findings suggest that PIU may represent a distinct, intermediate group of Internet users. The potential theoretical and practical implications of identifying PIU were also discussed.

    2017-01-01

    Full Text Available Internet mobile users are concerned more and more about their privacy nowadays as both researches and real world incidents show that leaking of communication and location privacy can lead to serious consequence, and many research works have been done to anonymize individual user from aggregated location data. However, just the communication itself between the mobile users and their peers or website could collect considerable privacy of the mobile users, such as location history, to other parties. In this paper, we investigated the potential privacy risk of mobile Internet users and proposed a scalable system built on top of public cloud services that can hide mobile user’s network location and traffic from communication peers. This system creates a dynamic distributed proxy network for each mobile user to minimize performance overhead and operation cost.

    2011-09-01

    Students in higher education, and scientific and technological researchers want to communicate with the International Space Station (ISS), download live satellite images, and receive telemetry, housekeeping and science/engineering data from nano-satellites and larger spacecrafts. To meet this need the Ecuadorian Civilian Space Agency (EXA) has recently provided the civilian world with an internet-to-orbit gateway (Hermes-A/Minotaur) Space Flight Control Center (SFCC) available for public use. The gateway has a maximum range of tracking and detection of 22,000 km and sensitivity such that it can receive and discriminate the signals from a satellite transmitter with power˜0.1 W. The capability is enough to receive the faintest low-earth-orbit (LEO) satellites. This gateway virtually connects participating internet clients around the world to a remote satellite ground station (GS), providing a broad community for multinational cooperation. The goal of the GS is to lower financial and engineering barriers that hinder access to science and engineering data from orbit. The basic design of the virtual GS on a user side is based on free software suites. Using these and other software tools the GS is able to provide access to orbit for a multitude of users without each having to go through the costly setups. We present the design and implementation of the virtual GS in a higher education and scientific outreach settings. We also discuss the basic architecture of the single existing system and the benefits of a proposed distributed system. Details of the software tools and their applicability to synchronous round-the-world tracking, monitoring and processing performed by students and teams at Graz University of Technology, Austria, EXA-Ecuador, University of Michigan, USA and JAXA who have participated in various mission operations and have investigated real-time satellite data download and image acquisition and processing.

    Parmi les outils dont disposent les scientifiques pour communiquer et échanger leurs connaissances, la revue apparaît comme le média de référence, le support officiel et légitime des publications formelles. La revue scientifique cristallise, dans ses modes de conception, de production, de diffusion et de vente, des logiques opposées (logiques scientifique, symbolique et marchande). L’émergence d’Internet conduit à une redéfinition des rôles et des logiques qui prévalaient jusqu’alors.

    2,4-Dinitrophenol (DNP) poses serious health-risks to humans. The aims of this three-stage multidisciplinary project were, for the first time, to assess the risks to the general public from fraudulent sale of or adulteration/contamination with DNP; and to investigate motives, reasons and risk-management among DNP-user bodybuilders and avid exercisers. Using multiple search-engines and guidance for Internet research, online retailers and bodybuilding forums/blogs were systematically explored for availability of DNP, advice offered on DNP use and user profiles. Ninety-eight pre-workout and weight-loss supplements were purchased and analysed for DNP using liquid-chromatography-mass-spectrometry. Psychosocial variables were captured in an international sample of 35 DNP users (26.06 ± 6.10 years, 94.3 % male) with an anonymous, semi-qualitative self-reported survey. Although an industrial chemical, evidence from the Internet showed that DNP is sold 'as is', in capsules or tablets to suit human consumption, and is used 'uncut'. Analytical results confirmed that DNP is not on the supplement market disguised under fictitious supplement names, but infrequently was present as contaminant in some supplements (14/98) at low concentration (<100mcg/kg). Users make conscious and 'informed' decisions about DNP; are well-prepared for the side-effects and show nonchalant attitude toward self-experimentation with DNP. Steps are often taken to ensure that DNP is genuine. Personal experience with performance- and appearance enhancing substances appears to be a gateway to DNP. Advice on DNP and experiences are shared online. The significant discrepancy between the normative perception and the actual visibility suggests that DNP use is-contrary to the Internet accounts-a highly concealed and lonesome activity in real life. Positive experiences with the expected weight-loss prevail over the negative experiences from side effects (all but two users considered using DNP again) and help

    There is continued discussion of including Internet dependence as a diagnosis in future editions of the Diagnostic and Statistical Manual of Mental Disorders. The primary aim of the study was to evaluate the utility of the proposed diagnostic criteria for Internet dependence as measured by Young's Diagnostic Questionnaire (YDQ). Although the YDQ does not provide any measure of severity, there is emerging recognition that some Internet users may display less severe or at risk Internet dependence. The degree to which the cutoff of 5 out of 8 criteria is appropriate to differentiate nondependent from dependent Internet use was evaluated by comparing the Internet usage and psychological dysfunction of 424 university students endorsing 3 and 4 diagnostic criteria (at-risk Internet dependence) to those endorsing less than 3 criteria (nondependent) and those endorsing 5 or more criteria (Internet dependence). The findings suggest that the proposed diagnostic criteria do not adequately discriminate individuals scoring 3 or 4 from those currently classified as Internet dependent. The implications of the findings for the assessment, diagnosis, and treatment of Internet dependence are discussed.

    'In much the same way that HTML and HTTP enabled WWW, the Open Geospatial Consortium (OGC) Sensor Web Enablement (SWE), envisioned in 2001 [1] will allow sensor webs to become a reality.'. Due to the large number of sensor manufacturers and differing accompanying protocols, integrating diverse sensors into observation systems is not a simple task. A coherent infrastructure is needed to treat sensors in an interoperable, platform-independent and uniform way. SWE standardizes web service interfaces, sensor descriptions and data encodings as building blocks for a Sensor Web. SWE standards are now mature specifications (version 2.0) with approved OGC compliance test suites and tens of independent implementations. Many earth and space science organizations and government agencies are using the SWE standards to publish and share their sensors and observations. While SWE has been demonstrated very effective for scientific sensors, its complexity and the computational overhead may not be suitable for resource-constrained tiny sensors. In June 2012, a new OGC Standards Working Group (SWG) was formed called the Sensor Web Interface for Internet of Things (SWE-IoT) SWG. This SWG focuses on developing one or more OGC standards for resource-constrained sensors and actuators (e.g., Internet of Things devices) while leveraging the existing OGC SWE standards. In the near future, billions to trillions of small sensors and actuators will be embedded in real- world objects and connected to the Internet facilitating a concept called the Internet of Things (IoT). By populating our environment with real-world sensor-based devices, the IoT is opening the door to exciting possibilities for a variety of application domains, such as environmental monitoring, transportation and logistics, urban informatics, smart cities, as well as personal and social applications. The current SWE-IoT development aims on modeling the IoT components and defining a standard web service that makes the

    Full Text Available CAPTCHA is one of the most common solutions to check if the user trying to enter a Website is a real person or an automated piece of software. This challenge-response test, implemented in many Internet Websites, emphasizes the gaps between accessibility and security on the Internet, as it poses an obstacle for the learning-impaired in the reading and comprehension of what is presented in the test. Various types of CAPTCHA tests have been developed in order to address accessibility and security issues. The objective of this study is to investigate how the differences between various CAPTCHA tests affect user experience among populations with and without learning disabilities. A questionnaire accompanied by experiencing five different tests was administered to 212 users, 60 of them with learning disabilities. Response rates for each test and levels of success were collected automatically. Findings suggest that users with learning disabilities have more difficulties in solving the tests, especially those with distorted texts, have more negative attitudes towards the CAPTCHA tests, but the response time has no statistical difference from users without learning disabilities. These insights can help to develop and implement solutions suitable for many users and especially for population with learning disabilities.

    The Heater of the Hypersonic Tunnel Facility (HTF) was modeled using SINDA/FLUINT thermal software. A description of the model is given. The project presented the opportunity of interfacing the thermal model with the Internet and was a demonstration that complex analysis is possible through the Internet. Some of the issues that need to be addressed related to interfacing software with the Internet are the following: justification for using the Internet, selection of the web server, choice of the CGI language, security of the system, communication among the parties, maintenance of state between web pages, and simultaneous users on the Internet system. The opportunities available for using the Internet for analysis are many and can present a significant jump in technology. This paper presents a vision how interfacing with the Internet could develop in the future. Using a separate Optical Internet (OI) for analysis, coupled with virtual reality analysis rooms (VRAR), could provide a synergistic environment to couple together engineering analysis within industry, academia, and government. The process of analysis could be broken down into sub-components so that specialization could occur resulting in superior quality, minimized cost and reduced time for engineering analysis and manufacturing. Some possible subcomponents of the system are solver routines, databases, Graphical User Interfaces, engineering design software, VRARs, computer processing, CAD systems, manufacturing, and a plethora of other options only limited by ones imagination. On a larger scope, the specialization of companies on the optical network would allow companies to rapidly construct and reconstruct their infrastructure based on changing economic conditions. This could transform business.

    2017-10-01

    Full Text Available To improve the quality of service and reduce the possibility of security attacks, a secure and efficient user authentication mechanism is required for Wireless Sensor Networks (WSNs and the Internet of Things (IoT. Session key establishment between the sensor node and the user is also required for secure communication. In this paper, we perform the security analysis of A.K.Das’s user authentication scheme (given in 2015, Choi et al.’s scheme (given in 2016, and Park et al.’s scheme (given in 2016. The security analysis shows that their schemes are vulnerable to various attacks like user impersonation attack, sensor node impersonation attack and attacks based on legitimate users. Based on the cryptanalysis of these existing protocols, we propose a secure and efficient authenticated session key establishment protocol which ensures various security features and overcomes the drawbacks of existing protocols. The formal and informal security analysis indicates that the proposed protocol withstands the various security vulnerabilities involved in WSNs. The automated validation using AVISPA and Scyther tool ensures the absence of security attacks in our scheme. The logical verification using the Burrows-Abadi-Needham (BAN logic confirms the correctness of the proposed protocol. Finally, the comparative analysis based on computational overhead and security features of other existing protocol indicate that the proposed user authentication system is secure and efficient. In future, we intend to implement the proposed protocol in real-world applications of WSNs and IoT.

    The World Wide Web can be a powerful tool for reaching the public as well as students and teachers around the world, supporting both formal and informal science education. The Windows to the Universe Project, initiated in 1995, provides a case study of approaches for the use of the web to support earth and space science education and literacy efforts. Through the use of innovative approaches such as easy to use design, multi-level content, and science concepts presented in a broader background context that includes connections to culture and the humanities, Windows to the Universe is an accessible format for individuals of various ages and learning styles. A large global audience regularly uses the web site to learn about earth and space science as well as related humanities content such as myths from around the world. User surveys show that the site has over 4 millions users per year, 65 percent of which are K-12 teachers and students. Approximately 46 percent of users access the site once per week or more. Recently, we have had the opportunity to expand our efforts while we continue to update existing content based on new scientific findings and events. Earth science content on Windows to the Universe is currently growing with a new geology section and development efforts are underway to expand our space weather content with a new curriculum. Educational games allow users to learn about space in a playful context, and an online journaling tool further integrates literacy into the learning experience. In addition, we are currently translating the entire Windows to the Universe web site into Spanish. We have included educators in the project as co-designers from its inception, and by aggressively utilizing and providing professional development opportunities for teachers, the web site is now used in thousands of classrooms around the world. In the past year we have continued to support K-12 educators by adding to our suite of classroom activities and leading

    Some of the most frequently used online applications are Facebook, WhatsApp, and Twitter. These applications allow individuals to communicate with other users, to share information or pictures, and to stay in contact with friends all over the world. However, a growing number of users suffer from negative consequences due to their excessive use of these applications, which can be referred to as Internet-communication disorder. The frequent use and easy access of these applications may also trigger the individual's fear of missing out on content when not accessing these applications. Using a sample of 270 participants, a structural equation model was analyzed to investigate the role of psychopathological symptoms and the fear of missing out on expectancies towards Internet-communication applications in the development of symptoms of an Internet-communication disorder. The results suggest that psychopathological symptoms predict higher fear of missing out on the individual's Internet-communication applications and higher expectancies to use these applications as a helpful tool to escape from negative feelings. These specific cognitions mediate the effect of psychopathological symptoms on Internet-communication disorder. Our results are in line with the theoretical model by Brand et al. (2016) as they show how Internet-related cognitive bias mediates the relationship between a person's core characteristics (e.g., psychopathological symptoms) and Internet-communication disorder. However, further studies should investigate the role of the fear of missing out as a specific predisposition, as well as specific cognition in the online context.

This report explains the relationship between the practice of Internet censorship imposed by the Chinese government and the freedom of its citizens (in the internet surfing experience as the realization of human rights in the freedom of expression and opinion (seek, receive-use, and communicate information which is traced through the relevant literature study. China is a unique case since the internet censorship regulation contributes to its status as the country with the least internet freedom yet at the same time it is credited as having the most internet users globally. In addition, China known as the communist country that began opening up to globalization and information of technology, but the government’s control over it is still so tight and binding, not only in the press, or the traditional media, but also in new media with the internet censorship. The control over this information may have a clear objective to maintain a climate of information in the community, but on the other hand, such control is tantamount to restricting the right of citizens to make, use, and distribute information, and more fatal as a violation of human rights.

    2013-12-01

    Responding to national science education reform documents calling for students to have more opportunities for authentic research experiences, several national projects have developed online telescope networks to provide students with Internet-access to research grade telescopes. The nature of astronomical observation (e.g., remote sites, expensive equipment, and odd hours) has been a barrier in the past. Internet-based robotic telescopes allow scientists to conduct observing sessions on research-grade telescopes half a world away. The same technology can now be harnessed by STEM educators to engage students and reinforce what is being taught in the classroom, as seen in some early research in elementary schools (McKinnon and Mainwaring 2000 and McKinnon and Geissinger 2002), middle/high schools (Sadler et al. 2001, 2007 and Gehret et al. 2005) and undergraduate programs (e.g., McLin et al. 2009). This project looks at the educational value of using Internet-based robotic telescopes in a general education introductory astronomy course at the undergraduate level. Students at a minority-serving institution in the midwestern United States conducted observational programs using the Global Telescope Network (GTN). The project consisted of the use of planetarium software to determine object visibility, observing proposals (with abstract, background, goals, and dissemination sections), peer review (including written reviews and panel discussion according to NSF intellectual merit and broader impacts criteria), and classroom presentations showing the results of the observation. The GTN is a network of small telescopes funded by the Fermi mission to support the science of high energy astrophysics. It is managed by the NASA E/PO Group at Sonoma State University and is controlled using SkyNet. Data includes course artifacts (proposals, reviews, panel summaries, presentations, and student reflections) for six semesters plus student interviews. Using a grounded theory approach

  16. LANGUAGE AWARENESS IN AN INTERNET CHAT ROOM

    Directory of Open Access Journals (Sweden)

    Leszek Szymański

    2013-10-01

    Full Text Available When communicating on the Internet, the participants, so to say, mingle two traditional modes of communication: writing and speech. The phenomenon appears to be most noticeable in chat room interactions. This suggestion is based on the fact that users try to behave as though they are engaged in a spoken act of communication, though the actual medium of communication employs written language forms. Therefore, Internet users need to know what conventions to employ and how to perform such actions in order to express the desired meanings, all with the aim of driving the interaction as close as possible to speech. Such implementations of certain language-related customs require a specific kind of language awareness from the users. This concept, plus the applied conventions, constitute the essence of this article. The discussion begins with an introduction to the research problem, in this case the intentional utilization by Internet chat participants of the graphic mode of communication in order to express their desired meanings. Second, the reader becomes acquainted with the terminology used in the paper, which includes: language awareness, (Internet chat, and (language corpus. Moreover, the source of the studied language material—a corpus of Internet chats—is presented. The said description additionally includes the informants’ characteristics, as well as the topicality of their conversations. The further sections of the paper discus the application of selected non-normative spelling conventions and word-formation processes, with the support of examples taken from the corpus. Based on the discussion, an attempt is made to indicate which features comprise certain values to the participants of Internet chats.

  17. Decision Making Under Uncertainty - Bridging the Gap Between End User Needs and Science Capability

    Successful adaptation outcomes depend on decision making based on the best available climate science information. However, a fundamental barrier exists, namely the 'gap' between information that climate science can currently provide and the information that is practically useful for end users and decision makers. This study identifies the major contributing factors to the 'gap' from an Australian perspective and provides recommendations as to ways in which the 'gap' may be narrowed. This was achieved via a literature review, online survey (targeted to providers of climate information and end users of that information), workshop (where both climate scientists and end users came together to discuss key issues) and focus group. The study confirmed that uncertainty in climate science is a key barrier to adaptation. The issue of uncertainty was found to be multi-faceted, with issues identified in terms of communication of uncertainty, misunderstanding of uncertainty and the lack of tools/methods to deal with uncertainty. There were also key differences in terms of expectations for the future - most end users were of the belief that uncertainty associated with future climate projections would reduce within the next five to 10 years, however producers of climate science information were well aware that this would most likely not be the case. This is a concerning finding as end users may delay taking action on adaptation and risk planning until the uncertainties are reduced - a situation which may never eventuate or may occur after the optimal time for action. Improved communication and packaging of climate information was another key theme that was highlighted in this study. Importantly, it was made clear that improved communication is not just about more glossy brochures and presentations by climate scientists, rather there is a role for a program or group to fill this role (coined a 'knowledge broker' during the workshop and focus group). The role of the 'knowledge

    Full Text Available Objectives: The social engagement and participation of older adults in society are seen as indicators of healthy ageing. With the changing nature of society over recent years, many elderly people are at risk of being lonely. Evidence shows that loneliness has an adverse effect on older adults. Therefore, it is important to find some ways to overcome this problem. This study aimed to assess the level of loneliness among Iranian retired teachers and the impact of Internet application on the sense of loneliness and depression in this group. Methods & Materials: This Cross-sectional study was conducted among 445 retired teachers which 43 of them were Internet user. Data collected by a questionnaire consisted of three sections including demographic questions, 15 questions of Social and Emotional Loneliness Scale (SELSA, and 5 GDS questions. Results: from a Principle Component Factor Analysis reduced SELSA items to a three-factor model including Social, Family and Romantic Subscales. For Internet users one more section was used including 3 parts: frequency, history and nature of Internet application. Data was analyzed by SPSS. Results T, 37% of the non-user respondents reported social loneliness compared to 18.6% of users (P=0.002 However prevalence of family loneliness in those who were non-user was significantly lower (P=0.001. Living alone, being widowed or separated were predictors of loneliness (P<0.05. Findings showed that, the level of depression in users were significantly lower than that of non-users (P=0.002 (27.9% followed by 39.2%.  Conclusion: These findings in combination suggest that the level of loneliness and depression among non-user retired people is almost higher than users. Therefore, it is important to identify and implement strategies such as using the Internet to overcome the loneliness experienced by elderly people.

    Full Text Available Background: Today, the Internet has become a part of our everyday life and online communications have made it easy for people to develop interpersonal relationships. However, certain problems and difficulties have arisen from this issue. One of these problems, which have been prevalent among couples and families, is extramarital internet relationships or internet infidelity. The present research has been done to study people's attitudes towards this phenomenon. Materials and Methods: A 43-item Internet Infidelity Questionnaire (IIQ was presented on a website designed for this purpose. 481 Iranian users who were members of Farsi language forums and chat rooms were selected through available community sampling and enrolled in the study. To analyze research data, descriptive statistics and the t-test were used.Results: The results showed that either women or men considered online sexual activities of their partners as traitorous compared with friendly and emotional activities in cyberspace. In addition, women in comparison with men had a more negative attitude towards their partners’ internet activity (especially online sexual activities.Conclusion: This study expanded our understanding of the traditional concept of infidelity that had merely limited it to face-to-face sexual and emotional behavior. The results also showed that women had more negative attitudes towards such activities compared to men.

    This study investigated the differences between non-excessive, moderately excessive, and highly excessive internet use among adolescents. These differences were explored in terms of personal characteristics, psychological difficulties, environmental factors, and manner of internet use. A representative sample was investigated, consisting of 18,709 adolescents aged 11-16 and their parents, from 25 European countries. Excessive internet use was measured using a five item scale covering following factors: salience, conflict, tolerance, withdrawal symptoms, and relapse and reinstatement. The main data analysis utilised multinomial and binary logistic regression models. The vast majority of respondents reported no signs of excessive internet use. Moderately excessive users (4.4%) reported higher emotional and behavioural difficulties, but also more sophisticated digital skills and a broader range of online activities. The highly excessive users (1.4%) differed from the non-excessive and moderately excessive users in their preference for online games and in having more difficulties with self-control. Adolescents who struggle with attention and self-control and who are inclined toward online gaming may be especially vulnerable to the otherwise uncommon phenomenon of excessive internet use.

    In this article we describe people’s online contribution practices in contexts in which the government actively blocks access to or censors the Internet. We argue that people experience blocking as confusing, as a motivation for self-censorship online, as a cause of impoverishment of available...... content and as a real threat of personal persecution. Challenging ideas of blocking as a monolithic, abstract policy, we discuss five strategies with which Internet users navigate blocking: self-censorship, cultivating technical savvy, reliance on social ties to relay blocked content, use of already...... in which all Internet users contribute to the Internet and social media....

    Full Text Available The current paper presents the results from some research on the relationship between Internet addiction, cyberchondria, and different aspects of well-being. The information available on the Internet, which is not necessarily truthful and accurate, can unreasonably amplify users health concerns. Problematic Internet use, health anxiety aroused by online searches for health information and escalation of health concerns as an indicator of cyberchondria, are all associated with a decrease in subjective and eudaimonic well-being as well as in self-esteem. The analyses indicate positive relationships between depressive symptoms on the one hand, and Internet addiction and health anxiety, on the other. A conclusion regarding the existence of a relationship between Internet addiction, cyberchondria and decreased levels of well-being could be drawn from the research. Furthermore, the results suggest that self-esteem and eudaimonic well-being correlate positively with the number of people with whom users communicate online.

    The Internet is a staple of electronic communication and is essential to the emerging telemonitoring and health information technology interventions for adults with chronic diseases. To identify determinants of frequent Internet use in an urban kidney transplant population in the United States. A single center, cross-sectional survey study. An urban Midwestern transplant center. 78 pretransplant and 177 posttransplant patients. Frequent Internet use, defined as using the Internet more than 5 hours per week. Only 38% of participants reported being frequent Internet users. Non-Hispanic blacks and participants who reported their race/ethnicity as "other" were significantly less likely than whites to report being frequent Internet users. Women were 59% less likely than men to be frequent users of the Internet. Those who reported having kidney disease for more than 3 years were more likely to report being frequent Internet users. As education increased, Internet use increased. As age increased, Internet use decreased. Alternatives to electronic information sources and/or additional resources should be considered for those who may fall in the so-called digital divide.

    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.

  14. Internet firewalls: questions and answers

    As organizations consider connecting to the Internet, the issue of internetwork security becomes more important. There are many tools and components that can be used to secure a network, one of which is a firewall. Modern firewalls offer highly flexible private network security by controlling and monitoring all communications passing into or out of the private network. Specifically designed for security, firewalls become the private network's single point of attack from Internet intruders. Application gateways (or proxies) that have been written to be secure against even the most persistent attacks ensure that only authorized users and services access the private network. One-time passwords prevent intruders from `sniffing' and replaying the usernames and passwords of authorized users to gain access to the private network. Comprehensive logging permits constant and uniform system monitoring. `Address spoofing' attacks are prevented. The private network may use registered or unregistered IP addresses behind the firewall. Firewall-to-firewall encryption establishes a `virtual private network' across the Internet, preventing intruders from eavesdropping on private communications, eliminating the need for costly dedicated lines.

    Even though public awareness about privacy risks in the Internet is increasing, in the evolution of the Internet to the Internet of Things (IoT) these risks are likely to become more relevant due to the large amount of data collected and processed by the "Things". The business drivers for exploring ways to monetize such data are one of the challenges identified in this paper for the protection of Privacy in the IoT. Beyond the protection of privacy, this paper highlights the need for new approaches, which grant a more active role to the users of the IoT and which address other potential issues such as the Digital Divide or safety risks. A key facet in ethical design is the transparency of the technology and services in how that technology handles data, as well as providing choice for the user. This paper presents a new approach for users' interaction with the IoT, which is based on the concept of Ethical Design implemented through a policy-based framework. In the proposed framework, users are provided with wider controls over personal data or the IoT services by selecting specific sets of policies, which can be tailored according to users' capabilities and to the contexts where they operate. The potential deployment of the framework in a typical IoT context is described with the identification of the main stakeholders and the processes that should be put in place.

    In Germany, the internet is used by 69.4% of the population or 49 million people, and 100% of adolescents (between 14 to 19 years of age) spend time in the internet at least occasionally. An excessive use of the internet may lead to negative psychosocial consequences and changes in behaviour. This phenomenon is named "pathological internet use". Until now, there are only few studies published that investigate mental well being in German adolescents with pathological internet use. 16 participants of an outpatient treatment program for pathological internet use and 16 healthy adolescents were compared on self-reported levels of psychopathology (SPS-J), achievement motivation (FLM 7-13) and personal experience of attention deficit (FEDA). There were no differences in age, gender, intelligence or education between the two groups. Pathological internet users exhibited significantly elevated scores on self-esteem problems and the summary score of the SPS-J and significantly lower scores on FLM 7-13-dimensions "achievement ambition" and "perseverance/diligence" compared to controls. The results revealed that adolescents with pathological internet use report a higher level of psychopathology and lower levels of achievement motivation and drive. These findings should be taken into account when conceptualizing treatments for pathological internet users.

    Objective To analyze speech reading through Internet video calls by profoundly hearing-impaired individuals and cochlear implant (CI) users. Methods Speech reading skills of 14 deaf adults and 21 CI users were assessed using the Hochmair Schulz Moser (HSM) sentence test. We presented video simulations using different video resolutions (1280×720, 640×480, 320×240, 160×120 px), frame rates (30, 20, 10, 7, 5 frames per second (fps)), speech velocities (three different speakers), webcameras (Logitech Pro9000, C600 and C500) and image/sound delays (0–500 ms). All video simulations were presented with and without sound and in two screen sizes. Additionally, scores for live Skype™ video connection and live face-to-face communication were assessed. Results Higher frame rate (>7 fps), higher camera resolution (>640×480 px) and shorter picture/sound delay (<100 ms) were associated with increased speech perception scores. Scores were strongly dependent on the speaker but were not influenced by physical properties of the camera optics or the full screen mode. There is a significant median gain of +8.5%pts (p = 0.009) in speech perception for all 21 CI-users if visual cues are additionally shown. CI users with poor open set speech perception scores (n = 11) showed the greatest benefit under combined audio-visual presentation (median speech perception +11.8%pts, p = 0.032). Conclusion Webcameras have the potential to improve telecommunication of hearing-impaired individuals. PMID:23359119

    2012-12-01

    The internet and social media have been a critical vector for misinformation on climate change. Scientists have not always been proactive or effective in utilizing the medium to bring attention to the best science, to correct misinformation and overcome urban myths. Similarly, mainstream journalists have been handicapped in dealing with the wide open nature of the medium, and often muted by editorial concerns or budget restrictions. Independent communicators who are highly motivated can make inroads in this area by using the internet's immediacy and connectivity to consistently connect viewers and readers to reliable information. Over the last 4 years, I have developed a series of you tube videos, made deliberately provocative to engage the internet's confrontational culture, but carefully crafted to bring the best science into the freewheeling community. In doing so, I have won the confidence of leading climate scientists, and in some cases assisted them in clarifying their message. This presentation will share simple tips, useful practices, and effective strategies for making complex material more clear and user friendly, and help scientists better convey the stories hidden in their data.

    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.

    Abstract The purpose of this study was to examine the prevalence of Internet addiction in a nationally representative sample of Chinese elementary and middle school students and to investigate Internet addiction among Internet users with different usages. The data were from the National Children's Study of China (NCSC) in which 24,013 fourth- to ninth-grade students were recruited from 100 counties in 31 provinces in China. Only 54.2% of the students had accessed the Internet. According to the criteria of Young's Diagnostic Questionnaire (YDQ), an eight-item instrument, the prevalence of Internet addiction in the total sample was 6.3%, and among Internet users was 11.7%. Among the Internet users, males (14.8%) and rural students (12.1%) reported Internet addiction more than females (7.0%) and urban students (10.6%). The percentage of Internet addicts in elementary school students (11.5%) was not significantly lower than the percentage of middle school students (11.9%). There was no statistically significant difference between the four geographical regions (9.6%, 11.5%, 12.3%, 11.1%) characterized by different levels of economy, health, education, and social environment. As the frequency of Internet use and time spent online per week increased, the percentage of Internet addicts increased. When considering the location and purpose of Internet use, the percentage of Internet addicts was highest in adolescents typically surfing in Internet cafes (18.1%) and playing Internet games (22.5%).

    Background Addicted Internet users present with higher rates of comorbidities, e.g., attention-deficit hyperactivity disorder (ADHD), depressive, and anxiety disorders. In addition, deficits in self-concept-related characteristics were found in addicted Internet gamers and social network users. The aim of this study was to examine the links between healthy, problematic, and addicted Internet use regarding comorbidities and self-concept-related characteristics. The association between recently developed ADHD-like symptoms without an underlying diagnosis and addictive Internet use was also examined. Methods n = 79 healthy controls, n = 35 problematic, and n = 93 addicted Internet users were assessed for comorbidities, social and emotional competencies, body image, self-esteem, and perceived stress. Apart from an ADHD-diagnosis, recently developed ADHD-like symptoms were also assessed. Results Addicted users showed more self-concept-related deficits and higher rates of comorbidities with ADHD, depressive, and anxiety disorders. Addicted and problematic users showed similarities in the prevalence of cluster B personality disorders and decreased levels of characteristics related to emotional intelligence. Participants with recently developed ADHD-like symptoms scored higher in lifetime and current severity of Internet use compared with those without ADHD symptoms. Addicted participants with recently developed ADHD symptoms showed higher lifetime Internet use severity compared with those without any symptoms. Conclusions Our findings indicate that cluster B personality disorders and premorbid problems in emotional intelligence might present a link between problematic and addictive Internet use. Furthermore, the findings provide a first indication that addictive Internet use is related to ADHD-like symptoms. Symptoms of ADHD should therefore be assessed against the background of possible addicted Internet use.

    Guided internet-based intervention beyond hearing aid (HA) fitting has been shown to be efficacious in randomised controlled trials (RCTs). However, internet interventions have rarely been applied clinically as a part of regular aural rehabilitation (AR). Our aim was to evaluate the effectiveness of internet-based AR for HA users from a clinical population. The Hearing Handicap Inventory for the Elderly (HHIE) was used as the primary outcome measure, and the Communication Strategies Scale (CSS) and the Hospital Anxiety and Depression Scale were used as secondary outcome measures. All questionnaires were administered before and directly after the intervention and at 6 months postintervention. We used a parallel group design (RCT). The data were collected in 2013-2014 at three different clinics. Seventy-four HA users were randomly assigned to receive either full internet-based AR (intervention group, n=37) or one element of the internet-based AR (control group, n=37). Data were analysed following the intention-to-treat principle. Each group showed improved HHIE scores over time and did not differ significantly from each other. The intervention group showed significantly greater improvement compared with the control group for the CSS total and the non-verbal subscale scores. The intervention group and control group were also subdivided into two age groups: 20-59 years and 60-80 years. Significantly better improvement on the CSS total and non-verbal subscale scores was found in the older group compared with the younger participants. This study indicates that participants in an internet-based intervention applied in general clinical practice showed improved self-reported communication skills compared with a control group. Receiving a full intervention was not more effective in improving self-reported hearing problems than receiving just one element of the internet-based intervention.

  10. Internet dynamics

    Science.gov (United States)

    Lukose, Rajan Mathew

    The World Wide Web and the Internet are rapidly expanding spaces, of great economic and social significance, which offer an opportunity to study many phenomena, often previously inaccessible, on an unprecedented scale and resolution with relative ease. These phenomena are measurable on the scale of tens of millions of users and hundreds of millions of pages. By virtue of nearly complete electronic mediation, it is possible in principle to observe the time and ``spatial'' evolution of nearly all choices and interactions. This cyber-space therefore provides a view into a number of traditional research questions (from many academic disciplines) and creates its own new phenomena accessible for study. Despite its largely self-organized and dynamic nature, a number of robust quantitative regularities are found in the aggregate statistics of interesting and useful quantities. These regularities can be understood with the help of models that draw on ideas from statistical physics as well as other fields such as economics, psychology and decision theory. This thesis develops models that can account for regularities found in the statistics of Internet congestion and user surfing patterns and discusses some practical consequences. practical consequences.

    Full Text Available The article aims to show that the classical document paradigm in information science has the greatest potential to grasp the issues related to the providing information to persons with visual disabilities and it aims to check whether the FRBR study is usable in this area. The article is divided into two parts. In the first part, the paradigmatic turns in information science are briefly presented and there is examined their impact on the issues connected with users with visual disabilities. The second part briefly describes the structure of the bibliographic universe and there is examined how it is possible to create a model of documents for users with visual impairment and of associated processes. The model of the bibliographic universe is applied to the situation of the really existing documents for visually impaired users. Methodologically, the article is based on the information system analysis. There is used an entity-relationship approach to a model of the bibliographic universe.

    Full Text Available Internet addiction has become a serious mental health condition in many countries. To better understand the clinical implications of Internet addiction, this study tested statistically a new theoretical model illustrating underlying cognitive mechanisms contributing to development and maintenance of the disorder. The model differentiates between a generalized Internet addiction (GIA and specific forms. This study tested the model on GIA on a population of general Internet users. The findings from 1019 users showed that the hypothesized structural equation model explained 63.5% of the variance of GIA symptoms, as measured by the short version of the Internet Addiction Test (s-IAT. Using psychological and personality testing, the results show that a person’s specific cognitions (poor coping and cognitive expectations increased the risk for generalized Internet addiction. These two factors mediated the symptoms of GIA if other risk factors were present such as depression, social anxiety, low self-esteem, low self-efficacy, and high stress vulnerability to name a few areas that were measured in the study. The model shows that individuals with high coping skills and no expectancies that the Internet can be used to increase positive or reduce negative mood are less likely to engage in problematic Internet use, even when other personality or psychological vulnerabilities are present. The implications for treatment include a clear cognitive component to the development of generalized Internet addiction and the need to assess a patient’s coping style and cognitions and improve faulty thinking to reduce symptoms and engage in recovery.

  16. Design and evaluation of an Internet based data repository and visualization system for science education

    Science.gov (United States)

    Dalphond, James M.

    In modern classrooms, scientific probes are often used in science labs to engage students in inquiry-based learning. Many of these probes will never leave the classroom, closing the door on real world experimentation that may engage students. Also, these tools do not encourage students to share data across classrooms or schools. To address these limitations, we have developed a web-based system for collecting, storing, and visualizing sensor data, as well as a hardware package to interface existing classroom probes. This system, The Internet System for Networked Sensor Experimentation (iSENSE), was created to address these limitations. Development of the system began in 2007 and has proceeded through four phases: proof-of-concept prototype, technology demonstration, initial classroom deployment, and classroom testing. User testing and feedback during these phases guided development of the system. This thesis includes lessons learned during development and evaluation of the system in the hands of teachers and students. We developed three evaluations of this practical use. The first evaluation involved working closely with teachers to encourage them to integrate activities using the iSENSE system into their existing curriculum. We were looking for strengths of the approach and ease of integration. Second, we developed three "Activity Labs," which teachers used as embedded assessments. In these activities, students were asked to answer questions based on experiments or visualizations already entered into the iSENSE website. Lastly, teachers were interviewed after using the system to determine what they found valuable. This thesis makes contributions in two areas. It shows how an iterative design process was used to develop a system used in a science classroom, and it presents an analysis of the educational impact of the system on teachers and students.

    Scientific research performed with the involvement of the broader public (the crowd) attracts increasing attention from scientists and policy makers. A key premise is that project organizers may be able to draw on underused human resources to advance research at relatively low cost. Despite a growing number of examples, systematic research on the effort contributions volunteers are willing to make to crowd science projects is lacking. Analyzing data on seven different projects, we quantify the financial value volunteers can bring by comparing their unpaid contributions with counterfactual costs in traditional or online labor markets. The volume of total contributions is substantial, although some projects are much more successful in attracting effort than others. Moreover, contributions received by projects are very uneven across time-a tendency toward declining activity is interrupted by spikes typically resulting from outreach efforts or media attention. Analyzing user-level data, we find that most contributors participate only once and with little effort, leaving a relatively small share of users who return responsible for most of the work. Although top contributor status is earned primarily through higher levels of effort, top contributors also tend to work faster. This speed advantage develops over multiple sessions, suggesting that it reflects learning rather than inherent differences in skills. Our findings inform recent discussions about potential benefits from crowd science, suggest that involving the crowd may be more effective for some kinds of projects than others, provide guidance for project managers, and raise important questions for future research.

  1. `Googling' Terrorists: Are Northern Irish Terrorists Visible on Internet Search Engines?

    Science.gov (United States)

    Reilly, P.

    In this chapter, the analysis suggests that Northern Irish terrorists are not visible on Web search engines when net users employ conventional Internet search techniques. Editors of mass media organisations traditionally have had the ability to decide whether a terrorist atrocity is `newsworthy,' controlling the `oxygen' supply that sustains all forms of terrorism. This process, also known as `gatekeeping,' is often influenced by the norms of social responsibility, or alternatively, with regard to the interests of the advertisers and corporate sponsors that sustain mass media organisations. The analysis presented in this chapter suggests that Internet search engines can also be characterised as `gatekeepers,' albeit without the ability to shape the content of Websites before it reaches net users. Instead, Internet search engines give priority retrieval to certain Websites within their directory, pointing net users towards these Websites rather than others on the Internet. Net users are more likely to click on links to the more `visible' Websites on Internet search engine directories, these sites invariably being the highest `ranked' in response to a particular search query. A number of factors including the design of the Website and the number of links to external sites determine the `visibility' of a Website on Internet search engines. The study suggests that Northern Irish terrorists and their sympathisers are unlikely to achieve a greater degree of `visibility' online than they enjoy in the conventional mass media through the perpetration of atrocities. Although these groups may have a greater degree of freedom on the Internet to publicise their ideologies, they are still likely to be speaking to the converted or members of the press. Although it is easier to locate Northern Irish terrorist organisations on Internet search engines by linking in via ideology, ideological description searches, such as `Irish Republican' and `Ulster Loyalist,' are more likely to

    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

    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.

    Some pregnant women use the internet to search for medical information. However, online information is not controlled. The objectives were to describe French online chats about drugs and pregnancy and evaluate the quality and reliability of information shared by internet users. This French descriptive study was performed in November 2012. In order to identify drugs and pregnancy-related forum websites, we used three French key words: forum, pregnancy and drug. We explored the first 10 websites from the search result. Diseases were described using the International Classification of Diseases and drugs classified with the Anatomical Therapeutic Chemical codes and the FDA risk classification. We selected 115 questions that were mainly posted by pregnant internet users in French forums. Drugs raising questions were mostly "nervous system," "anti-infective for systemic use" and "respiratory system" drugs. The risk during pregnancy for nearly half of these drugs had not been evaluated properly. Health professionals were only involved in 7% of the 214 answers. Internet users advised to take a drug in 21% of their answers. Thirty-four percent of those recommended drugs had not been well-evaluated or were potentially at risk during pregnancy. Finally, 12% of the answers could be at risk for pregnant woman. This study shows that information related to drugs and pregnancy in online chats could be at risk for pregnant women. Internet users must be aware that online forums are not reliable sources of information. Copyright © 2014 John Wiley & Sons, Ltd.

    To determine test-re-test reliability of the 'Computer User Profile' (CUP) in people with and without TBI. The CUP was administered on two occasions to people with and without TBI. The CUP investigated the nature and frequency of participants' computer and Internet use. Intra-class correlation coefficients and kappa coefficients were conducted to measure reliability of individual CUP items. Descriptive statistics were used to summarize content of responses. Sixteen adults with TBI and 40 adults without TBI were included in the study. All participants were reliable in reporting demographic information, frequency of social communication and leisure activities and computer/Internet habits and usage. Adults with TBI were reliable in 77% of their responses to survey items. Adults without TBI were reliable in 88% of their responses to survey items. The CUP was practical and valuable in capturing information about social, leisure, communication and computer/Internet habits of people with and without TBI. Adults without TBI scored more items with satisfactory reliability overall in their surveys. Future studies may include larger samples and could also include an exploration of how people with/without TBI use other digital communication technologies. This may provide further information on determining technology readiness for people with TBI in therapy programmes.

    The novel technology of the Internet of Things (IoT) connects objects to the Internet and its most advanced applications refine obtained data for the user. We propose that Internet of Things technology can be used to promote basic nursing care in the hospital environment by improving the quality of care and patient safety. To introduce the concept of Internet of Things to nursing audience by exploring the state of the art of Internet of Things based technology for basic nursing care in the hospital environment. Scoping review methodology following Arksey & O'Malley's stages from one to five were used to explore the extent, range, and nature of current literature. We searched eight databases using predefined search terms. A total of 5030 retrievals were found which were screened for duplications and relevancy to the study topic. 265 papers were chosen for closer screening of the abstracts and 93 for full text evaluation. 62 papers were selected for the review. The constructs of the papers, the Internet of Things based innovations and the themes of basic nursing care in hospital environment were identified. Most of the papers included in the review were peer-reviewed proceedings of technological conferences or articles published in technological journals. The Internet of Things based innovations were presented in methodology papers or tested in case studies and usability assessments. Innovations were identified in several topics in four basic nursing care activities: comprehensive assessment, periodical clinical reassessment, activities of daily living and care management. Internet of Things technology is providing innovations for the use of basic nursing care although the innovations are emerging and still in early stages. Internet of things is yet vaguely adopted in nursing. The possibilities of the Internet of Things are not yet exploited as well as they could. Nursing science might benefit from deeper involvement in engineering research in the area of health

    The Multimedia Medical Data Archive and Retrieval Server has been installed at the imaging science and information systems (ISIS) center in Georgetown University Medical Center to provide medical data archive and retrieval support for medical researchers. The medical data includes text, images, sound, and video. All medical data is keyword indexed using a database management system and placed temporarily in a staging area and then transferred to a StorageTek one terabyte tape library system with a robotic arm for permanent archive. There are two methods of interaction with the system. The first method is to use a web browser with HTML functions to perform insert, query, update, and retrieve operations. These generate dynamic SQL calls to the database and produce StorageTek API calls to the tape library. The HTML functions consist of a database, StorageTek interface, HTTP server, common gateway interface, and Java programs. The second method is to issue a DICOM store command, which is translated by the system's DICOM server to SQL calls and then produce StorageTek API calls to the tape library. The system performs as both an Internet and a DICOM server using standard protocols such as HTTP, HTML, Java, and DICOM. Users with proper authentication can log on to the server from anywhere on the Internet using a standard web browser resulting in a user-friendly, open environment, and platform independent solution for archiving multimedia medical data. It represents a complex integration of different components including a robotic tape storage system, database, user-interface, WWW protocols, and TCP/IP networking. The user will only deal with the WWW and DICOM server components of the system, the database and robotic tape library system are transparent and the user will not know that the medical data is stored on magnetic tapes. The server provides the researchers a cost-effective tool for archiving and retrieving medical data across a TCP/IP network environment. It will

    The current study aimed to establish the prevalence of internet gaming disorder (IGD) and its association with demographic characteristics, game genre, game use (time spent on gaming), as well as psychological distress, social phobia and well-being among current online gamers in Singapore. A total of 1251 participants aged 13 to 40 years completed the study which was administered as a web survey. The online questionnaire was designed using QuestionPro, and consisted of 8 sections and 105 questions. The 9-item Internet Gaming Disorder Questionnaire was used to establish the prevalence of IGD in the study. A series of logistic regression models were used to examine the associations between IGD, demographic characteristics and game genre, as well as IGD and psychological distress, social phobia and well-being. The prevalence of IGD established using a cutoff of 5 among those who were current online gamers was 17.7%. Multiple logistic regressions revealed that those meeting criteria of IGD were more likely to be older, reported an earlier age of onset of playing online games, had primary and secondary education versus tertiary education, were currently students versus being currently employed and played massively multiplayer online role-playing games. Distress and social anxiety were higher while satisfaction with life was significantly lower among those who met criteria for IGD than those who did not meet the criteria. The prevalence of IGD and its negative consequences in our sample of current online gamers was significant and point towards the need for further clinical studies and innovative interventions to address the problem.

    2014-01-01

    In recent years, research indicated that the problematic effects of Internet use must be examined together with individual differences present in its users with which such effects are contingent. This study examined loneliness in adolescents as a mediator of the relationship between shyness and their generalized problematic Internet use (PIU). A total of 1469 adolescents (48.5% male, 51.5% female) from Grade 8 and Grade 9 classes participated in this study. Using the Social Reticence Scale (SRS), the revised UCLA Loneliness scale and the Generalized Problematic Internet Use scale, initial findings indicated significant correlations among the three variables. Results from the study further revealed that loneliness completely mediated the relationship between shyness and generalized problematic Internet use. Implications for intervention work addressing both loneliness and shyness issues facing adolescents who are problematic users of the Internet were discussed.

    Full Text Available The Western perspective in examining the political impact of the Internet concentrates on whether this new medium will revitalize the public sphere so as to further representative democracy to ideal form of participatory democracy. This paper examines the political impact of the Internet on China, a large developing country that lacks sophisticated representative democratic politics. It analyzes the revolutionary changes that the Internet has brought to the Chinese Internet users and the government's regulations on the new medium. It asks whether the Internet will form the Habermasian public sphere in China and concludes that the Internet enhances the Chinese netter's political participation, but it needs long-term research to decide to what extent the Internet will improve democracy in China.

    There is growing importance of the Internet Addiction Test (IAT) in Internet addiction research around the world. Since the development of the IAT (Young, 1996, 1998), a number of validation studies have been done in various cultures. The aim of this study was to translate the instrument into Bangla and validate in Bangladeshi culture, a culture vulnerable to Internet addiction. A total of 177 Internet users (77 females and 100 males) participated in the study. Exploratory factor analysis (EFA) of the data from 172 participants (who provided complete responses) identified a four factor structure of the IAT with 18 items. The four factors namely 'Neglect of duty', 'Online dependence', 'Virtual fantasies', and 'Privacy and self-defense' together explained 55.68% of the total variance. Problematic (moderate/excessive) users on the IAT scored, on average, higher on each of the four IAT factors as compared to average or non-problematic (minimal) users consistently across genders. The IAT and its factors showed good internal consistency (Cronbach's α=.89 for the IAT, and .60-.84 for the factors), strong convergent and discriminant validity. Thus, the Bangla version IAT appears to be valid and reliable and therefore may be used in further research on Internet addiction in the country. Copyright © 2013 Elsevier B.V. All rights reserved.

    Highlights: > A dual-chambered internet-accessible heavily shielded facility has been built. > The facility allows distance users to analyze neutron irradiated samples remotely. > The Missouri S and T system uses computer automation with user feedback. > The system can analyze multiple samples and assist several researchers concurrently. - Abstract: A dual-chambered internet-accessible heavily shielded facility with pneumatic access to the University of Missouri Science and Technology (Missouri S and T) 200 kW Research Nuclear Reactor (MSTR) core has been built and is currently available for irradiation and analysis of samples. The facility allows authorized distance users engaged in collaborative activities with Missouri S and T to remotely manipulate and analyze neutron irradiated samples. The system consists of two shielded compartments, one for multiple sample storage, and the other dedicated exclusively for radiation measurements and spectroscopy. The second chamber has multiple detector ports, with graded shielding, and has the capability to support gamma spectroscopy using radiation detectors such as an HPGe detector. Both these chambers are connected though a rapid pneumatic system with access to the MSTR nuclear reactor core. This new internet-based system complements the MSTR's current bare pneumatic tube (BPT) and cadmium lined pneumatic tube (CPT) facilities. The total transportation time between the core and the hot cell, for samples weighing 10 g, irradiated in the MSTR core, is roughly 3.0 s. This work was funded by the DOE grant number DE-FG07-07ID14852 and expands the capabilities of teaching and research at the MSTR. It allows individuals who do not have on-site access to a nuclear reactor facility to remotely participate in research and educational activities.

    Citizen science enables volunteers to contribute to scientific projects, where massive data collection and analysis are often required. Volunteers participate in citizen science activities online from their homes or in the field and are motivated by both intrinsic and extrinsic factors. Here, we investigated the possibility of integrating citizen science tasks within physical exercises envisaged as part of a potential rehabilitation therapy session. The citizen science activity entailed environmental mapping of a polluted body of water using a miniature instrumented boat, which was remotely controlled by the participants through their physical gesture tracked by a low-cost markerless motion capture system. Our findings demonstrate that the natural user interface offers an engaging and effective means for performing environmental monitoring tasks. At the same time, the citizen science activity increases the commitment of the participants, leading to a better motion performance, quantified through an array of objective indices. The study constitutes a first and necessary step toward rehabilitative treatments of the upper limb through citizen science and low-cost markerless optical systems.

  4. Internet Use and the Political Knowledge Gap in Spain

    2012-04-01

    Full Text Available Media availability and fragmentation and the resulting possibilities of content selection have risen dramatically with the expansion of new digital media. Previous research has found that this may increase knowledge gaps among citizens with different resources and motivations. This article analyses how Internet use affects political knowledge gaps due to education and to political interest in Spain. As expected, frequent Internet users are more knowledgeable about politics than non-users. Furthermore, Internet use increases knowledge more for the highly educated than for citizens with lower levels of education. Thus, the political knowledge gap related to education seems to be growing with the introduction of new media. However, the knowledge gap between citizens with high and low levels of political interest is smaller for frequent Internet users than for non-users. These findings provide a complex picture and partially contradict the pessimistic theory about the impact of increasing media choice on political knowledge.

    La disponibilidad y fragmentación de medios de comunicación y las posibilidades de elegir contenidos han aumentado en gran medida a raíz de la expansión de los medios digitales. Éstos pueden, según investigaciones anteriores, incrementar las diferencias en los niveles de conocimiento entre ciudadanos con distintas características. En este artículo se analiza cómo el uso de Internet afecta a las diferencias en el conocimiento político según el nivel educativo y el interés por la política en España. Los usuarios frecuentes de Internet saben más sobre política que los no usuarios, como era de esperar. Además, el uso de Internet incrementa el conocimiento político de manera más intensa para los usuarios con niveles educativos más elevados. Por tanto, parece que las diferencias en los niveles de conocimiento pueden estar creciendo con la expansión de los medios digitales. Sin embargo, las diferencias

    Background and objectives The ubiquitous Internet connections by smartphones weakened the traditional boundaries between computers and mobile phones. We sought to explore whether smartphone-related problems differ from those of computer use according to gender using latent class analysis (LCA). Methods After informed consents, 555 Korean middle-school students completed surveys on gaming, Internet use, and smartphone usage patterns. They also completed various psychosocial instruments. LCA was performed for the whole group and by gender. In addition to ANOVA and χ 2 tests, post-hoc tests were conducted to examine differences among the LCA subgroups. Results In the whole group (n = 555), four subtypes were identified: dual-problem users (49.5%), problematic Internet users (7.7%), problematic smartphone users (32.1%), and "healthy" users (10.6%). Dual-problem users scored highest for addictive behaviors and other psychopathologies. The gender-stratified LCA revealed three subtypes for each gender. With dual-problem and healthy subgroup as common, problematic Internet subgroup was classified in the males, whereas problematic smartphone subgroup was classified in the females in the gender-stratified LCA. Thus, distinct patterns were observed according to gender with higher proportion of dual-problem present in males. While gaming was associated with problematic Internet use in males, aggression and impulsivity demonstrated associations with problematic smartphone use in females. Conclusions An increase in the number of digital media-related problems was associated with worse outcomes in various psychosocial scales. Gaming may play a crucial role in males solely displaying Internet-related problems. The heightened impulsivity and aggression seen in our female problematic smartphone users requires further research.

    2015-01-01

    Studies have identified high rates and severe consequences of Internet Addiction/Pathological Internet Use (IA/PIU) in university students. However, most research concerning IA/PIU in U.S. university students has been conducted within a quantitative research paradigm, and frequently fails to contextualize the problem of IA/PIU. To address this gap, we conducted an exploratory qualitative study using the focus group approach and examined 27 U.S. university students who self-identified as intensive Internet users, spent more than 25 hours/week on the Internet for non-school or non-work-related activities and who reported Internet-associated health and/or psychosocial problems. Students completed two IA/PIU measures (Young’s Diagnostic Questionnaire and the Compulsive Internet Use Scale) and participated in focus groups exploring the natural history of their Internet use; preferred online activities; emotional, interpersonal, and situational triggers for intensive Internet use; and health and/or psychosocial consequences of their Internet overuse. Students’ self-reports of Internet overuse problems were consistent with results of standardized measures. Students first accessed the Internet at an average age of 9 (SD = 2.7), and first had a problem with Internet overuse at an average age of 16 (SD = 4.3). Sadness and depression, boredom, and stress were common triggers of intensive Internet use. Social media use was nearly universal and pervasive in participants’ lives. Sleep deprivation, academic under-achievement, failure to exercise and to engage in face-to-face social activities, negative affective states, and decreased ability to concentrate were frequently reported consequences of intensive Internet use/Internet overuse. IA/PIU may be an underappreciated problem among U.S. university students and warrants additional research. PMID:25647224

    Knowledge about user experiences may lead to insights about how to improve treatment activity in Internet-based cognitive behavioral therapy (iCBT) to reduce symptoms of depression and anxiety among people with a somatic disease. There is a need for studies conducted alongside randomized trials, to explore treatment activity and user experiences related to such interventions, especially among people with older age who are recruited in routine care. The aim of the study was to explore treatment activity, user satisfaction, and usability experiences among patients allocated to treatment in the U-CARE Heart study, a randomized clinical trial of an iCBT intervention for treatment of depression and anxiety following a recent myocardial infarction. This was a mixed methods study where quantitative and qualitative approaches were used. Patients were recruited consecutively from 25 cardiac clinics in Sweden. The study included 117 patients allocated to 14 weeks of an iCBT intervention in the U-CARE Heart study. Quantitative data about treatment activity and therapist communication were collected through logged user patterns, which were analyzed with descriptive statistics. Qualitative data with regard to positive and negative experiences, and suggestions for improvements concerning the intervention, were collected through semistructured interviews with 21 patients in the treatment arm after follow-up. The interviews were analyzed with qualitative manifest content analysis. Treatment activity was low with regard to number of completed modules (mean 0.76, SD 0.93, range 0-5) and completed assignments (mean 3.09, SD 4.05, range 0-29). Most of the participants initiated the introduction module (113/117, 96.6%), and about half (63/117, 53.9%) of all participants completed the introductory module, but only 18 (15.4%, 18/117) continued to work with any of the remaining 10 modules, and each of the remaining modules was completed by 7 or less of the participants. On average

    It is a challenge to access and process fast growing Earth science data from satellites and numerical models, which may be archived in very different data format and structures. NASA data centers, managed by the Earth Observing System Data and Information System (EOSDIS), have developed a rich and diverse set of data services and tools with features intended to simplify finding, downloading, and working with these data. Although most data services and tools have user guides, many users still experience difficulties with accessing or reading data due to varying levels of familiarity with data services, tools, and/or formats. A type of structured online document, data recipe, were created in beginning 2013 by Goddard Earth Science Data and Information Services Center (GES DISC). A data recipe is the How-To document created by using the fixed template, containing step-by-step instructions with screenshots and examples of accessing and working with real data. The recipes has been found to be very helpful, especially to first-time-users of particular data services, tools, or data products. Online traffic to the data recipe pages is significant to some recipes. In 2014, the NASA Earth Science Data System Working Group (ESDSWG) for data recipes was established, aimed to initiate an EOSDIS-wide campaign for leveraging the distributed knowledge within EOSDIS and its user communities regarding their respective services and tools. The ESDSWG data recipe group started with inventory and analysis of existing EOSDIS-wide online help documents, and provided recommendations and guidelines and for writing and grouping data recipes. This presentation will overview activities of creating How-To documents at GES DISC and ESDSWG. We encourage feedback and contribution from users for improving the data How-To knowledge base.

    A major use of the of the internet is for health information-seeking. There has been little research into its use in relation to mental health. To investigate the prevalence of internet use for mental health information-seeking and its relative importance as a mental health information source. General population survey. Questions covered internet use, past psychiatric history and the 12-item General Health Questionnaire. Eighteen per cent of all internet users had used the internet for information related to mental health. The prevalence was higher among those with a past history of mental health problems and those with current psychological distress. Only 12% of respondents selected the internet as one of the three most accurate sources of information, compared with 24% who responded that it was one of the three sources they would use. The internet has a significant role in mental health information-seeking. The internet is used more than it is trusted.

    In Poland, like in other European countries and in accordance with the global trend, the number of computer users and people who have access to the Internet has increased considerably. The study investigates trends and patterns of Polish health-related Internet use over a period of seven years. The main objective of the study was to estimate the change in the proportion of the population using Internet for health purposes and to show the potential trend in perceptions and preferences of Polish citizens in this respect as well as factors affecting their use. The study was based on three national surveys that were conducted in 2005, 2007, and 2012. A total of 3027 adult citizens were selected randomly from the Polish population. A sample collection was carried out by Polish opinion poll agencies by computer-assisted telephone interviews. The subjects were asked to respond to general questions about their Internet use and their Internet use for health-related purposes, as well as to express their opinions about various sources of medical information, frequency, and the need for direct communication with health professionals via the Internet and other interactive forms of online activities. The proportion of the Polish population that used the Internet for health-related purposes increased significantly (41.7% in 2005, 53.3% in 2007, and 66.7% in 2012). The Internet has become an important source of health information for almost half of Polish citizens, overtaking television, radio, press, and courses or lectures in the ranking list. As the medium matures, the use of interactive, health-related online services has also increased remarkably. However, while the main users of the Internet are certainly younger people, the largest growth potential has been observed among the elderly. The profile of the most likely Internet user and the citizen for whom the Internet is an important source of health information has been determined. The Internet offers enormous opportunities

    NASA's future communications services will be supplied through a space communications network that mirrors the terrestrial Internet in its capabilities and flexibility. The notional requirements for future data gathering and distribution by this Space Internet have been gathered from NASA's Earth Science Enterprise (ESE), the Human Exploration and Development in Space (HEDS), and the Space Science Enterprise (SSE). This paper describes a communications infrastructure for the Space Internet, the architectures within the infrastructure, and the elements that make up the architectures. The architectures meet the requirements of the enterprises beyond 2010 with Internet 'compatible technologies and functionality. The elements of an architecture include the backbone, access, inter-spacecraft and proximity communication parts. From the architectures, technologies have been identified which have the most impact and are critical for the implementation of the architectures.

    Full Text Available As international politics' developments heavily weigh on Russia's domestic politics, the internet is placed on top of the list of "threats" that the government must tackle, through an avalanche of legislations aiming at gradually isolating the Russian internet from the global infrastructure. The growth of the Russian internet market during the last couple of years is likely to remain secondary to the "sovereignisation" of Russia's internet. This article aims at understanding these contradictory trends, in an international context in which internet governance is at a crossroads, and major internet firms come under greater regulatory scrutiny from governments. The Russian 'dictatorship-of-the-law' paradigm is all but over: it is deploying online, with potentially harmful consequences for Russia's attempts to attract foreign investments in the internet sector, and for users' rights online.

    Technological advancement benefits Internet users with the convenience of social connection and information search. This study aimed at investigating the predictors of Internet use to search for online health information among Chinese older adults. The Technology Acceptance Model (TAM) was applied to examine the predictiveness of perceived ease of use, perceived usefulness, and attitudes toward Internet use on behavioral intention to search for health information online. Ninety-eight Chinese older adults were recruited from an academic institute for older people and community centers. Frequency of Internet use and physical and psychological health were also assessed. Results showed that perceived ease of use and attitudes significantly predicted behavioral intention of Internet use. The potential influences of traditional Chinese values and beliefs in health were also discussed.

    2014-01-01

    Internet addiction (IA) has become a serious mental health condition in many countries. To better understand the clinical implications of IA, this study tested statistically a new theoretical model illustrating underlying cognitive mechanisms contributing to development and maintenance of the disorder. The model differentiates between a generalized Internet addiction (GIA) and specific forms. This study tested the model on GIA on a population of general Internet users. The findings from 1019 users show that the hypothesized structural equation model explained 63.5% of the variance of GIA symptoms, as measured by the short version of the Internet Addiction Test. Using psychological and personality testing, the results show that a person's specific cognitions (poor coping and cognitive expectations) increased the risk for GIA. These two factors mediated the symptoms of GIA if other risk factors were present such as depression, social anxiety, low self-esteem, low self-efficacy, and high stress vulnerability to name a few areas that were measured in the study. The model shows that individuals with high coping skills and no expectancies that the Internet can be used to increase positive or reduce negative mood are less likely to engage in problematic Internet use, even when other personality or psychological vulnerabilities are present. The implications for treatment include a clear cognitive component to the development of GIA and the need to assess a patient's coping style and cognitions and improve faulty thinking to reduce symptoms and engage in recovery.

The objective of this study is to have empirical evidence about problematic internet use condition among teenagers as Facebook users in West Jakarta. This research is a descriptive study. Sample of this study was 82 high school students in West Jakarta. They were given GPIUS2 questionnaire constructed by Caplan. Result of the study is most of the teenagers have low score on problematic internet use especially in Facebook usage. The result is supported by the passiveness of Facebook online activity among the teenagers. However, there was a positive significant correlation between problematic internet use (PIU and teenagers’ feeling when their smartphone was left behind at home. It means they could not access their Facebook account for some time. This result is important for parents and educators to consider, given that Facebook has both positive and negative effect for teenagers.

    ABSTRACT: Lexicographers working on finance dictionaries have not properly exploited the fast development of the Internet. This is revealed by the poor utilization of the access routes found in current Internet finance dictionaries. Consequently, users cannot effectively and efficiently find answers to their lexicographical problems. Firstly, there are Internet finance dictionaries which lack technological features and can simply be called meagre Internet dictionaries. Secondly, there are Internet finance dictionaries which utilize so many technological features that users incur high lexicographical information costs. In order to create better access routes, a sound theoretical foundation has to be established. This article shows that the implementation of the modern theory of lexicographical functions, which focuses on the users, results in a better design for future Internet finance dictionaries. With the proper theoretical basis, lexicographers will be able to create state-ofthe- art dictionaries that can provide effective and efficient solutions to lexicographical problems.

    We describe in this paper a part of a telemetric network which consists of a workstation with photonic measurement and communication interfaces, structural fiber optic cabling (10/100BaseFX and CAN-FL), and photonic sensors with fiber optic interfaces. The station is equipped with direct photonic measurement interface and most common measuring standards converter (RS, GPIB) with fiber optic I/O CAN bus, O/E converters, LAN and modem ports. The station was connected to the Intranet (ipx/spx) and Internet (tcp/ip) with separate IP number and DNS, WINS names. Virtual measuring environment system program was written specially for such an Intranet and Internet station. The measurement system program communicated with the user via a Graphical User's Interface (GUI). The user has direct access to all functions of the measuring station system through appropriate layers of GUI: telemetric, transmission, visualization, processing, information, help and steering of the measuring system. We have carried out series of thorough simulation investigations and tests of the station using WWW subsystem of the Internet. We logged into the system through the LAN and via modem. The Internet metrological station works continuously under the address http://nms.ipe.pw.edu.pl/nms. The station and the system hear the short name NMS (from Network Measuring System).

    The aim of this study was to evaluate the interest in the Internet and its usage for health-related issues among people eligible for osteoporosis screening. Self-administered questionnaires have been distributed to subjects who were screened for osteoporosis and to menopausal women. 177 patients have responded to the survey (64.5 ± 10.1 years, 88.1% of women). There are 78.5% of Internet users. Among them, 67.2% said searching information about their health and 74.5% said using the Internet for this purpose. All respondents attributed an average score, out of 10, of 5.7 ± 2.3 regarding the reliability of information that they could find on the Internet. The use of the Internet differs significantly depending on age: those who use the Internet are younger (62.1 ± 8.91 years) than those who do not use it (73.3 ± 9.42 years). The socioeconomic status also has an impact on the Internet use: Internet users have a higher education, are more professionally active and have a higher net monthly household income compared to the group of non-users. Even if age and socioeconomic status appear to be determining factors in the use of the Internet for the search of health information in patients eligible for osteoporosis screening, almost 75% of the study population use the Internet for this purpose. Action to promote health through an Internet platform must therefore take these parameters into account.

    An increasing number of breast cancer patients are accessing the Internet for medical information. A survey was administered to breast cancer patients and their families attending follow-up outpatient clinics in a comprehensive cancer care center to explore their frequency of Internet use, their motivation for online activity, the type of information they sought, and the perceived impact of the information they found on the Internet on their medical care. The survey was conducted over a 4-month period. A total of 107 surveys were returned. Seventy-nine of these (74%) were from patients while 28 (26%) were from family members and friends. Thirty-four of the patient responses (43%) indicated that the patient had used the Internet to look for cancer-related information. Patients who had used the Internet to access cancer-related information were significantly younger (P = 0.007), better educated (P = 0.027), and less satisfied with the amount of treatment-related information given by caregivers than those patients who had not used the Internet to access cancer-related information (P = 0.032). The majority of patient Internet users desired more information on their cancer and its treatment (91%), looked up information that was presented to them by their clinicians (66%), researched other treatment options (63%), and obtained more information on "alternative treatments" (63%). Patient Internet users generally found the cancer-related information on the Internet to be useful, and the majority discussed Internet-derived information with their health care providers and perceived that clinicians listened to such information. However, 53% were undecided about the trustworthiness of the medical information obtained via the Internet. Internet nonusers commonly lacked Internet access (53%) or were unfamiliar with the Internet (33%), but few (13%) distrusted Internet-derived information. This exploratory study underscores the need for more research in this area, specifically

    The Internet is rapidly changing the ways we communicate information around the globe today. The desire to provide Internet-based services to anyone, anywhere, anytime has brought satellite communications to the forefront to become an integral part of the Internet. In spite of the distances involved, satellite links are proving to be capable of providing Internet services based on Internet protocol (TCP/IP) stack. This development has led to the question particularly at NASA; can satellites and other space platforms become an Internet-node in space? This will allow the direct transfer of information directly from space to the users on Earth and even be able to control the spacecraft and its instruments. NASA even wants to extend the near earth space Internet to deep space applications where scientists and the public here on Earth may view space exploration in real time via the Internet. NASA's future solar system exploration will involve intensive in situ investigations of planets, moons, asteroids, and comets. While past missions typically involved a single fly-by or orbiting science spacecraft, future missions will begin to use fleets of small, highly intelligent robotic vehicles to carry out collaborative investigations. The resulting multi-spacecraft topologies will effectively create a wide area network spanning the solar system. However, this will require significant development in Internet technologies for space use. This paper provides the status'of the Internet for near earth applications and the potential extension of the Internet for use in deep space planetary exploration. The paper will discuss the overall challenges of implementing the space Internet and how the space Internet will integrate into the complex terrestrial systems those forms the Internet of today in a hybrid set of networks.

    1999-12-01

    Full Text Available Internet provides a convenient environment to share geographic information. Web GIS (Geographic Information System even provides users a direct access environment to geographic databases through Internet. However, the complexity of geographic data makes it difficult for users to understand the real content and the limitation of geographic information. In some cases, users may misuse the geographic data and make wrong decisions. Meanwhile, geographic data are distributed across various government agencies, academic institutes, and private organizations, which make it even more difficult for users to fully understand the content of these complex data. To overcome these difficulties, this research uses metadata as a guiding mechanism for users to fully understand the content and the limitation of geographic data. We introduce three metadata standards commonly used for geographic data and metadata authoring tools available in the US. We also review the current development of geographic metadata standard in Taiwan. Two metadata authoring tools are developed in this research, which will enable users to build their own geographic metadata easily.[Article content in Chinese

    Internet technology can provide a diverse array of online resources for low-income disabled and homebound older adults to manage their health and mental health problems and maintain social connections. Despite many previous studies of older adults' Internet use, none focused on these most vulnerable older adults. This study examined Internet use patterns, reasons for discontinued use, eHealth literacy, and attitudes toward computer/Internet use among low-income homebound individuals aged 60 and older in comparison to their younger counterparts-homebound adults under age 60. Face-to-face or telephone surveys were conducted with 980 recipients of home-delivered meals in central Texas (78% were age 60 years and older and 22% under age 60). The eHealth Literacy Scale (eHEALS) and the efficacy and interest subscales of the Attitudes Toward Computer/Internet Questionnaire (ATC/IQ) were used to measure the respective constructs. Age groups were compared with chi-square tests and t tests. Correlates of Internet use were analyzed with multinomial logistic regression, and correlates of eHEALS and ATC/IQ scores were analyzed with OLS regression models. Only 34% of the under-60 group and 17% of the 60 years and older group currently used the Internet, and 35% and 16% of the respective group members reported discontinuing Internet use due to cost and disability. In addition to being older, never users were more likely to be black (OR 4.41; 95% CI 2.82-6.91, Pincomes (OR 0.36; 95% CI 0.27-0.49, Pincomes. Among both age groups, approximately three-fourths of the current users used the Internet every day or every few days, and their eHEALS scores were negatively associated with age and positively associated with frequency of use. Among the 60 and older group, a depression diagnosis was also negatively associated with eHEALS scores. ATC/IQ efficacy among never users of all ages and among older adults was positively associated with living alone, income, and the number of medical

    The primary aim of the study was to examine the relationship between Internet exposure and body image concern in adolescent girls, with a particular focus on the social networking site of Facebook. A sample of 1,087 girls in the first two years (Years 8 and 9) of high school (aged 13-15 years) completed questionnaire measures of Internet consumption and body image concerns. The overwhelming majority of girls (95.9%) had access to the Internet in their home. Time spent on the Internet was significantly related to internalization of the thin ideal, body surveillance, and drive for thinness. Further, 75% of the girls had a Facebook profile, and spent an average of 1.5 hours there daily. Facebook users scored significantly more highly on all body image concern measures than non-users. It was concluded that the Internet represents a potent socio-cultural medium of relevance to the body image of adolescent girls. Copyright © 2013 Wiley Periodicals, Inc.

    Primary science teachers in Scotland have a new updating method at their disposal with the launch of a package of CDi (Compact Discs Interactive) materials developed by the BBC and the Scottish Office. These were a response to the claim that many primary teachers felt they had been inadequately trained in science and lacked the confidence to teach it properly. Consequently they felt the need for more in-service training to equip them with the personal understanding required. The pack contains five disks and a printed user's guide divided up as follows: disk 1 Investigations; disk 2 Developing understanding; disks 3,4,5 Primary Science staff development videos. It was produced by the Scottish Interactive Technology Centre (Moray House Institute) and is available from BBC Education at £149.99 including VAT. Free Internet distribution of science education materials has also begun as part of the Global Schoolhouse (GSH) scheme. The US National Science Teachers' Association (NSTA) and Microsoft Corporation are making available field-tested comprehensive curriculum material including 'Micro-units' on more than 80 topics in biology, chemistry, earth and space science and physics. The latter are the work of the Scope, Sequence and Coordination of High School Science project, which can be found at http://www.gsh.org/NSTA_SSandC/.

    The Fukushima Daiichi nuclear power plant accident (FDNPPA) was the world's second largest nuclear power plant accident. At the time that it occurred, internet usage prevalence in Japan was as high as 80%. To compare health knowledge on radiation and preventive behaviour between internet users and non-users among adults employed in industries in Fukushima after the nuclear disaster. We conducted a cross-sectional questionnaire study among adults employed in industries in Fukushima 3-5 months after the FDNPPA. Targets were 1394 regular workers who took part in health seminars provided by the Fukushima Occupational Health Promotion Center. After applying the selection criteria, there were 1119 eligible participants. The questionnaire asked for personal characteristics and main sources of information about the FDNPPA, as well as health knowledge on radiation and preventive behaviours following the nuclear accident. We assessed the contribution of each variable using logistic regression analysis. Among the eligible respondents, 637 workers (56.9%) were internet users and 482 (43.1%) were non-users. Internet users had more health knowledge than non-users (average 4.6 radiation-related health conditions in internet users vs 3.6 conditions in non-users) and more preventive behaviours (average 2.6 behaviours in internet users vs 1.9 in non-users). According to logistic regression analyses, internet usage was positively associated with greater health knowledge on radiation (OR 1.13; 95% CI 1.08 to 1.20) and more preventive behaviours (OR 1.14; 95% CI 1.07 to 1.23). Internet usage was significantly and positively associated with greater health knowledge and more preventive behaviours. The internet is a useful method of distributing information to the general public in emergency situations such as a nuclear disaster. Published by the BMJ Publishing Group Limited.

    Full Text Available Although the neural substrates of cue reactivity in Internet gaming disorder (IGD have been examined in previous studies, most of these studies focused on the comparison between IGD subjects and healthy controls, which cannot exclude a potential effect of cue-familiarity. To overcome this limitation, the current study focuses on the comparison between IGD subjects and recreational Internet game users (RGU who play online games recreationally but do not develop dependence. Data from 40 RGU and 30 IGD subjects were collected while they were performing an event-related cue reactivity task in the fMRI scanner. The results showed that the IGD subjects were associated with enhanced activation in the left orbitofrontal cortex (OFC and decreased activation in the right anterior cingulate cortex (ACC, right precuneus, left precentral gyrus and right postcentral gyrus in comparison with the RGU subjects. OFC is involved in reward evaluation and ACC is implicated in executive control function based on previous researches. Moreover, the activation of OFC were correlated with the desire for game-playing. Thus, the higher activation in OFC might suggests high desire for game playing, and the lower activation in ACC might indicates impaired ability in inhibiting the urge to gaming-related stimuli in IGD subjects. Additionally, decreased activation in the precuneus, the precentral and postcentral gyrus may suggest the deficit in disentangling from game-playing stimuli. These findings explain why IGD subjects develop dependence on game-playing while RGU subjects can play online games recreationally and prevent the transition from voluntary game-playing to eventually IGD.

    Background : Understanding the risk factors associated with Internet gaming disorder (IGD) is important to predict and diagnose the condition. The purpose of this study is to identify risk factors that predict IGD based on psychological factors and Internet gaming characteristics; Methods : Online surveys were conducted between 26 November and 26 December 2014. There were 3568 Korean Internet game users among a total of 5003 respondents. We identified 481 IGD gamers and 3087 normal Internet gamers, based on Diagnostic and Statistical Manual for Mental Disorders (DSM-5) criteria. Logistic regression analysis was applied to identify significant risk factors for IGD; Results : The following eight risk factors were found to be significantly associated with IGD: functional and dysfunctional impulsivity (odds ratio: 1.138), belief self-control (1.034), anxiety (1.086), pursuit of desired appetitive goals (1.105), money spent on gaming (1.005), weekday game time (1.081), offline community meeting attendance (2.060), and game community membership (1.393; p < 0.05 for all eight risk factors); Conclusions : These risk factors allow for the prediction and diagnosis of IGD. In the future, these risk factors could also be used to inform clinical services for IGD diagnosis and treatment.

    Full Text Available Background: In recent years, the Internet has become one of the most popular sources of health information for users, and pregnant women are no exception. This study aimed to investigate Internet usage among pregnant women for achieving health information on the finding of related studies. Materials and Methods: This review study was conducted by searching databases such as IranMedex, Magiran, Scientific Information Database, Irandoc, PubMed, Science Direct, Cochrane, Google Scholar, and Scopus in December 2016. Restrictions were placed on publication to within 16 years and language of publication was restricted to English and Persian. Keywords used in the search included information-seeking behavior, information-seeking, information needs, access to information, pregnancy, and pregnant women. Results: This search resulted in 106 related publications and among them sixteen articles met inclusion criteria. This review showed that the use of the Internet by pregnant women was driven by information needs, ease, and speed of access and finding people with the same situation. Fetal development, symptoms, and complications of pregnancy, prenatal tests and nutrition, activities during pregnancy, and stages of delivery were the most often mentioned topics of interest. The benefits of internet use include reduced anxiety, personal support, creating an emotional connection and an increased confidence. Conclusions: Health providers must have sufficient ability for interpreting the achieved information from the Internet and should allocate efficient amount of time for discussing information-seeking manners with pregnant women. Furthermore, they must try to respond to the doubts of pregnant women and provide valid and reliable online educational resources.

    2009-01-01

    This paper discusses trends of Internet use for health or illness matters in Portugal. It is based on two waves of the WHO/Europe eHealth Consumer Trends Survey that took place in 2005 and 2007. The investigation involves 3001 complete interviews to individuals between 15 and 80 years old. Results show that the percentage of the Portuguese population reporting having used the Internet for health or illness matters has increased in average 9.1% (IC 95%, 5.5-12.6) in the 18 months that mediate the two surveys. The analysis by geographical region shows that there are no statistically significant differences between the five studied regions. The analysis by gender and age shows that the difference between men and women is diminishing but detects important exceptions, namely, a Sharp predominance of women in the group of individuals aged 15-34 years old that use the Internet for health or illness matters and the prevalence of men in the age levels 45-54 and 65-80 years old. The analysis by level of education completed show that the use is particularly high among those with complete higher education studies, with an increase of 8.2% (IC 95%, -.6-17.0) in the period under analysis. However, a significant increase has been observed among the Portuguese with before A-level studies, particularly when considering the group of Internet users for health purposes, where it has raised from four users in each ten individuals in 2005 to six users in each ten individuals in 2007. Reading health Web sites is the health related activity that more Portuguese attracts to the Internet but in the restricted group of Internet health users is the activity with higher positive variation in the period (9.2%, IC 95%, 5.3-13.2). Health professionals are still considered as the most important source of health information but their perceived importance has decreased 10% (IC 95%, -12.6, -7.6) between 2005 and 2007, the higher negative variation in this period.

    Prior work has demonstrated that religious beliefs and moral attitudes are often related to sexual functioning. The present work sought to examine another possibility: Do sexual attitudes and behaviors have a relationship with religious and spiritual functioning? More specifically, do pornography use and perceived addiction to Internet pornography predict the experience of religious and spiritual struggle? It was expected that feelings of perceived addiction to Internet pornography would indeed predict such struggles, both cross-sectionally and over time, but that actual pornography use would not. To test these ideas, two studies were conducted using a sample of undergraduate students (N = 1519) and a sample of adult Internet users in the U.S. (N = 713). Cross-sectional analyses in both samples found that elements of perceived addiction were related to the experience of religious and spiritual struggle. Additionally, longitudinal analyses over a 1-year time span with a subset of undergraduates (N = 156) and a subset of adult web users (N = 366) revealed that perceived addiction to Internet pornography predicted unique variance in struggle over time, even when baseline levels of struggle and other related variables were held constant. Collectively, these findings identify perceived addiction to Internet pornography as a reliable predictor of religious and spiritual struggle.

    Background The Internet is bringing fundamental changes to medical practice through improved access to health information and participation in decision making. However, patient preferences for participation in health care vary greatly. Promoting patient-centered health care requires an understanding of the relationship between Internet use and a broader range of preferences for participation than previously measured. Objective To explore (1) whether there is a significant relationship between Internet use frequency and patients’ overall preferences for obtaining health information and decision-making autonomy, and (2) whether the relationships between Internet use frequency and information and decision-making preferences differ with respect to different aspects of health conditions. Methods The Health Information Wants Questionnaire (HIWQ) was administered to gather data about patients’ preferences for the (1) amount of information desired about different aspects of a health condition, and (2) level of decision-making autonomy desired across those same aspects. Results The study sample included 438 individuals: 226 undergraduates (mean age 20; SD 2.15) and 212 community-dwelling older adults (mean age 72; SD 9.00). A significant difference was found between the younger and older age groups’ Internet use frequencies, with the younger age group having significantly more frequent Internet use than the older age group (younger age group mean 5.98, SD 0.33; older age group mean 3.50, SD 2.00; t 436=17.42, PInternet use frequency was positively related to the overall preference rating (γ=.15, PInternet users preferred significantly more information and decision making than infrequent Internet users.

    Full Text Available Private actors in the information technology sector are currently playing an increasingly important role in content mediation, as well as in regulation of online forms of expression, with implications for both internet rights and economic freedom. The “privatisation of internet governance” (DeNardis, 2010, is not a new dynamic; however, in a scenario in which users are taking advantage of increasingly sophisticated technology, the centralisation and concentration characterising today’s most widespread internet services are contributing to the accentuation of this tendency. The 'inherently political' qualities of search engine algorithm development, video content removals, blocking of domain names – actions that originate and rest with the private sector’s handling of the internet’s infrastructure – should not be neglected in our assessment of the field of internet governance today.

    Science software is integral to the scientific process and must be developed and managed in a sustainable manner to ensure future access to scientific data and related resources. Organizations that are part of the scientific enterprise, as well as members of the scientific community who work within these entities, can contribute to the sustainability of science software and to practices that improve scientific community capabilities for science software sustainability. As science becomes increasingly digital and therefore, dependent on software, improving community practices for sustainable science software will contribute to the sustainability of science. Members of the Earth science informatics community, including scientific data producers and distributers, end-user scientists, system and application developers, and data center managers, use science software regularly and face the challenges and the opportunities that science software presents for the sustainability of science. To gain insight on practices needed for the sustainability of science software from the science software experiences of the Earth science informatics community, an interdisciplinary group of 300 community members were asked to engage in simultaneous roundtable discussions and report on their answers to questions about the requirements for improving scientific software sustainability. This paper will present an analysis of the issues reported and the conclusions offered by the participants. These results provide perspectives for science software sustainability practices and have implications for actions that organizations and their leadership can initiate to improve the sustainability of science software.

  3. Public Library Representations and Internet Appropriations

    Directory of Open Access Journals (Sweden)

    Paula Sequeiros

    2013-11-01

    Full Text Available May the changes in the representations of the public library be propitiated by readers' appropriations of the Internet? To answer this question, a theoretically-driven and empirically-based research was developed in a public library in Portugal, combining the analysis of documents uses, the ethnography of space and Internet use, of social relations developed while reading, with the analysis of representations of the public library. No clear-cut association emerged between social-demographics or user profiles, and representations, in general. No disruptive Internet "impact" was found: Internet use may contribute to reinforce traditional representations of the library, while it may also update and democratise other representations. If the library and the Internet are represented as synonymous, the former does not make sense without the latter; but an Internet widespread and intensive use conflicts with the image of an institution dedicated to high-brow culture. Changes in uses of the public library are, instead, clearly associated with new types of readers, which in their turn reflect changes in urban social composition.

    The Californium User Facility for Neutron Science has been established at Oak Ridge National Laboratory (ORNL). The Californium User Facility (CUF) is a part of the larger Californium Facility, which fabricates and stores compact 252 Cf neutron sources for worldwide distribution. The CUF can provide a cost-effective option for research with 252 Cf sources. Three projects at the CUF that demonstrate the versatility of 252 Cf for biological and biomedical neutron-based research are described: future establishment of a 252 Cf-based neutron activation analysis system, ongoing work to produce miniature high-intensity, remotely afterloaded 252 Cf sources for tumor therapy, and a recent experiment that irradiated living human lung cancer cells impregnated with experimental boron compounds to test their effectiveness for boron neutron capture therapy

    The Internet has revolutionized the way knowledge is currently produced, stored and disseminated. A few finger clicks on a keyboard can save time and many hours of search in libraries or shopping in stores. Online trademarks with an (e-) prefix such as e-library, e-business, e-health etc., are increasingly part of our daily professional vocabularies. However, the Internet has also produced multiple negative side effects, ranging from an unhealthy dependency to a dehumanization of human relationships. Fraudulent, unethical and scam practices are also flourishing through for example misleading online advertising methods. Some social and professional networks gather users' profiles for selling and advertising purposes, sometimes by making it technically difficult to unsubscribe. Here, I discuss some of these unethical aspects and propose some potential solutions to reduce them.

    Full Text Available Computers in the 1980s were seen as a way to liberate people from the constraints of physicality, to expand the horizons of knowledge, and to enhance access to information. But after a few somersaults, we are back to a market that closes rather than opens our horizons, one that monopolizes, and even de facto owns, our very information. With the adoption of the term “user” - as opposed to “participant” for example – an asymmetry of power is underlined. This linguistic choice enables Internet platforms (such as Twitter, Facebook, iCloud, GoogleDrive to maintain shady property rights on what users might perceive as public spaces (precisely because they are built to project a public space dynamic but are in fact spaces in which the control over users' own data (e.g. pictures, texts is often impossible, transforming such data into a commodity and reducing users to (used consumers. En la década de 1980, los ordenadores se contemplaban como una forma de liberar a la gente de las limitaciones del mundo físico, ampliar los horizontes del conocimiento, y mejorar el acceso a la información. Pero después de diversos giros, volvemos a estar en un mercado que cierra nuestros horizontes en lugar de ampliarlos, que monopoliza, e incluso posee de facto, nuestra propia información. Con la adopción del término "usuario" - en lugar de "participante", por ejemplo - se pone de manifiesto la asimetría de poder existente. Esta opción lingüística permite a las plataformas de Internet (como Twitter, Facebook, iCloud, GoogleDrive mantener derechos de propiedad poco claros sobre plataformas que los usuarios pueden percibir como espacios públicos (precisamente porque están construidas para parecer un espacio público dinámico pero son en realidad espacios en los que es a menudo imposible controlar los propios datos de los usuarios (por ejemplo, imágenes, textos, transformando estos datos en una mercancía y convirtiendo a los usuarios en

    Full Text Available Anders Johan W Andersen,1 Tommy Svensson21Department of Psychosocial Health, University of Agder, Grimstad, Norway; 2Department of Behavioural Sciences and Learning, Linköping University, Linköping, SwedenAbstract: The Internet has enlarged the scope of human communication, opening new avenues for connecting with people who are struggling with their lives. This article presents a discourse analysis of 101 responses to 98 questions that were posted on 14 different Internet-based mental health services in Norway and Sweden. We aimed to examine and describe the dominant understandings and favored recommendations in the services’ answers, and we reflected upon the social consequences of those answers. The services generally understood life struggles as an abnormal state of mind, life rhythms, or self-reinforcing loops. Internet-based mental health services primarily counsel service users to seek help, talk to health care professionals face-to-face, and discuss their life struggles openly and honestly. They also urge service users to take better care of themselves and socialize with other people. However, such answers might enhance the individualization of life problems, masking social origin and construction. Consequently, the services are challenged to include social explanations in their answers and strengthen their responsibility to amplify peoples’ messages at a societal level. Potentially, such answers could strengthen democratic structures and put pressure on social equity.Keywords: depression, e-mental health, health psychology, Internet, public health

  18. User-Generated Services Composition in Smart Multi-User Environments

    Full Text Available The increasing complexity shown in Smart Environments, together with the spread of social networks, is increasingly moving the role of users from simple information and services consumers to actual producers. In this work, we focus on security issues raised by a particular kind of services: those generated by users. User-Generated Services (UGSs are characterized by a set of features that distinguish them from conventional services. To cope with UGS security problems, we introduce three different policy management models, analyzing benefits and drawbacks of each approach. Finally, we propose a cloud-based solution that enables the composition of multiple UGSs and policy models, allowing users’ devices to share features and services in Internet of Things (IoT based scenarios.
