    2005-09-01

    Full Text Available Despite the expanded use of the Internet for language learning and practice, little attention if any has been given to the quality of interaction among English L2 speakers in conversational text or voice chat rooms. This study explored the patterns of repair moves in synchronous non-native speaker (NNS text chat rooms in comparison to voice chat rooms on the Internet. The following questions were posed: (a Which types of repair moves occur in text and voice chats; and (b what are the differences, if any, between the repair moves in text chats and voice chats when time is held constant? Repair moves made by anonymous NNSs in 10, 5-minute, synchronous chat room sessions (5 text-chat sessions, 5 voice-chat sessions were counted and analyzed using chi-square with alpha set at .05. Significant differences were found between the higher number of total repair moves made in voice chats and the smaller number in text chats. Qualitative data analysis showed that repair work in voice chats was often pronunciation-related. The study includes discussion that may affect teachers' and learners' considerations of the value of NNS chat room interaction for second language development.

It was recently proposed to use the so-called Bayesian information criterion (BIC) approximation, for estimation of such probabilities of competing hypotheses. Here, we apply this approach to the understanding of chat. We show that ICA...... can detect meaningful context structures in a chat room log file....

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

    Directory of Open Access Journals (Sweden)

    Ana Paula Gonçalves Donate

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

  10. How useful are bounded online chat rooms as a source of pastoral support in a sixth-form college?

    OpenAIRE

    Richards, Catherine

    2009-01-01

    Since the introduction of chat technology there has been resistance within education to fully engage with it partly due to policy making that has left teachers disempowered (UCLAN 2002:66). Unlike other innovative technologies, its use has been limited. Pastoral support has developed significantly in education but in some instances, like chat rooms, has been viewed with scepticism. One reason for this scepticism may be that a clear measurable link between support and achievement is not easily...

    2016-03-01

    Full Text Available The paper represents the analysis of the narratives that deal with the sentiment of national belonging in Montenegro within the chat room Café del Montenegro. The practice of the Internet chat room users is perceived as cultural engagement – „practicing" the State and the emotion of national identification of its own kind. By writing, arguing, negotiating the meaning of the state and nation an abundance of different and broken knowledge’s are created- many histories, geographies, ethics and politics are offered. On the one hand, these directly undermines, jeopardizes and questions the power of the State narrative, hitherto negotiating the nation, the State, authentic devotion, simultaneously manufacturing the state-nation as a reality. The result of mutual correspondence in the chat room is persistent negotiation of the meaning of national categories in Montenegro over the years.

    2013-03-01

    Full Text Available The technological aids available in public schools may be used during teaching experiences through methods and methodologies which provide the student an extensive network of opportunities to (reconfigure their way of building knowledge in a foreign language, in order to reflect on their own learning approach. From this perspective, beyond the reflection and desire to use these tools, an autonomous and active attitude by the student is essential in order to use significant environments with on-line activities. An experience was conducted with high school first graders at a public school in a country town of the State of Goiás, aiming at identifying and analyzing the possibilities for the use of the foreign language (English by employing Omegle.com chat tool. This is  a free random chat that allows people from all over the world to interact in several languages, Twenty-one participants used the chat to interact in English with several people from different places in of the world. The data include chat dialogues as well as others collected by means of questionnaires, a researcher journal and classroom observation notes. Results show that the experience, which was inedited in this context of investigation, was developed with enthusiasm by the participants who, through the chat, improved their communication in an independent way.

  16. An exploratory study of Internet-initiated sexual offenses and the chat room sex offender: has the Internet enabled a new typology of sex offender?

    Briggs, Peter; Simon, Walter T; Simonsen, Stacy

    2011-03-01

    This exploratory study examined 51 participants convicted of an Internet-initiated sex offense in which they attempted to entice an adolescent into a sexual relationship using an Internet chat room. All participants were convicted of a sex offense and subject to an evaluation as a part of sentencing requirements in Colorado. Clinical and behavioral data were obtained from each subject's offense-specific evaluation and chat room transcripts. The results of the study found that 90% of the participants were apprehended as a result of an Internet sex sting. The authors conclude that Internet chat room sex offenders constitute a separate group characterized by less severe criminogenic factors than other sex offenders (rapists, child molesters). It can be hypothesized that chat room sex offenders avoid relationships and spend a significant amount of time in online chat rooms as a primary social and sexual outlet, and engage in other sexually compulsive behaviors. Within this offender group, it was discovered that two subgroups exist: a contact-driven group motivated to engage in offline sexual behavior with an adolescent and a fantasy-driven group motivated to engage an adolescent in online cybersex without an express intent to meet offline. The chat room sex offender presents a significant clinical issue to treatment providers as a live victim does not exist. Thus, it is unclear if Internet sex stings prevent incidents of child sexual exploitation and may result in convictions of individuals who may never have abused a child. The data suggest a tentative sex offender typology, including subtypes, which need to be replicated in future studies.

    This phenomenological enquiry into cyberspace examines the concept of space and metaphor, explaining ‘cyber’space as a figurative term and a figurative space, as something projected as a shared mental concept. Reception theory is used to theorize this figurative space as an ideational object cons...... constituted by a ‘text-reader’ relationship. The performance of ‘cyber’space is described as a self-reflexive ideation about meaning making itself, and examined as discursive, liminal, and transformative.

  1. The use of chat rooms in the internet: an exploratory study about the motivations, habits and attitudes of adolescents

    Directory of Open Access Journals (Sweden)

    Ana Cristina Garcia Dias

    2006-06-01

    Full Text Available The present study aims at investigating adolescents’ motivations, habits and attitudes in the use of internet chatrooms. 128 São Paulo High School and University students answered a specially devised questionnaire. Results showed no significant gender differences concerning the reasons for using chatrooms. The most frequent motivations were “having fun” and “meeting people”. More female subjects admitted to relying on ficticious characters when interacting in chatrooms, while more male subjects considered it easier to disclose personal matters in chatrooms than in face-to-face interactions (they seem to feel more protected in the virtual space. Most participants tended not to use chatrooms in order to solve personal problems, although one fourth of the sample recognized that the chats contributed to learning about oneself. As a conclusion, chatrooms are mainly seen as an environment for having fun, unable to foster a significantly different type of communication from the one(s established in face-to-face interactions.   Keywords: internet; communication; adolescence.

  2. Open of chat rooms for discussing geological disposal issues and review of adequate approaches for offering the information using the internet

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

    The concept of the sacred world beyond the stars found expression in the works of Plato, into Gnosticism and was incorporated into Christianity where medieval images of the cosmos pictured the heavenly domain as beyond the stars. Today cyberspace literature abounds with descriptions of a transmundane space, a great Beyond. This talk looks at current views of cyberspace and asks if they are a re-packaging of the age-old concept of a sacred sky in a secular and technological format?

  5. Immersive cyberspace system

    Park, Brian V. (Inventor)

    1997-01-01

    An immersive cyberspace system is presented which provides visual, audible, and vibrational inputs to a subject remaining in neutral immersion, and also provides for subject control input. The immersive cyberspace system includes a relaxation chair and a neutral immersion display hood. The relaxation chair supports a subject positioned thereupon, and places the subject in position which merges a neutral body position, the position a body naturally assumes in zero gravity, with a savasana yoga position. The display hood, which covers the subject's head, is configured to produce light images and sounds. An image projection subsystem provides either external or internal image projection. The display hood includes a projection screen moveably attached to an opaque shroud. A motion base supports the relaxation chair and produces vibrational inputs over a range of about 0-30 Hz. The motion base also produces limited translation and rotational movements of the relaxation chair. These limited translational and rotational movements, when properly coordinated with visual stimuli, constitute motion cues which create sensations of pitch, yaw, and roll movements. Vibration transducers produce vibrational inputs from about 20 Hz to about 150 Hz. An external computer, coupled to various components of the immersive cyberspace system, executes a software program and creates the cyberspace environment. One or more neutral hand posture controllers may be coupled to the external computer system and used to control various aspects of the cyberspace environment, or to enter data during the cyberspace experience.

  11. Avatar, Identitas dalam Cyberspace

    Directory of Open Access Journals (Sweden)

    Maria Nala Damayanti

    2013-01-01

    Full Text Available Human dependence on technology will have implications for a new culture of communication. Culture is related to the person behind the presence of elements of verbal or visual communication through internet media. Communication established via the Internet, known as cyberspace, allows the presence of a person in a variety of virtual identities. These identities emerge through verbal and visual appearances. They have names and shapes but can be present in any kind of form, commonly called avatars. The identity of a person can be represented by a number of different avatars capable of having more than one party at the same time. Communication that exists in cyberspace exceed time and space. The presence of these identities clearly indicates a relationship model that has a specific purpose. It could be a model of social relations that promote friendship, excitement, a sense of play, a critical mind or with other purposes. But the presence of such virtual identity cannot simply be equated with human beings as their personal identity in the real world, because in cyberspace, identity is plural and fluid. It can even be made with a hidden agenda.

  12. Cyberspace regulation: cesurist and traditionalists

    2015-05-01

    Full Text Available In the amazing Code and Other Laws of Cyberspace, Professor L. Lessig writes "that something fundamental has changed" with cyberspace with regard to the state's ability to enforce the law. On the one hand, the structure and characteristics of cyberspace pose some difficulties related to jurisdiction and the choice of applicable law. On the other, it raises questions about the very concept of sovereignty as we know it. This paper examines the arguments of those who advocate a regulation of cyberspace on the edges of state sovereignty or within a new concept of sovereignty and capacity to enforce the law, and the arguments of those who reject this exceptional treatment of cyberspace.

    1993-01-01

    Exploration and colonization of the universe awaits, but Earth-adapted biological humans are ill-equipped to respond to the challenge. Machines have gone farther and seen more, limited though they presently are by insect-like behavior inflexibility. As they become smarter over the coming decades, space will be theirs. Organizations of robots of ever increasing intelligence and sensory and motor ability will expand and transform what they occupy, working with matter, space and time. As they grow, a smaller and smaller fraction of their territory will be undeveloped frontier. Competitive success will depend more and more on using already available matter and space in ever more refined and useful forms. The process, analogous to the miniaturization that makes today's computers a trillion times more powerful than the mechanical calculators of the past, will gradually transform all activity from grossly physical homesteading of raw nature, to minimum-energy quantum transactions of computation. The final frontier will be urbanized, ultimately into an arena where every bit of activity is a meaningful computation: the inhabited portion of the universe will be transformed into a cyberspace. Because it will use resources more efficiently, a mature cyberspace of the distant future will be effectively much bigger than the present physical universe. While only an infinitesimal fraction of existing matter and space is doing interesting work, in a well developed cyberspace every bit will be part of a relevant computation or storing a useful datum. Over time, more compact and faster ways of using space and matter will be invented, and used to restructure the cyberspace, effectively increasing the amount of computational spacetime per unit of physical spacetime. Computational speed-ups will affect the subjective experience of entities in the cyberspace in a paradoxical way. At first glimpse, there is no subjective effect, because everything, inside and outside the individual

    The first step in preparing any battlespace is to define the domain for attack and maneuver. The various military service components have directed authority to focus their efforts in specific domains of operations (e.g., naval operations are mainly in the maritime domain). However, cyberspace operations pose challenges because they span multiple operational domains. This paper focuses on U.S. cyberspace policy related to defending and exploiting critical infrastructure assets. Also, it examines the issues involved in delineating responsibility for U.S. defensive and offensive operations related to critical infrastructures.

    Social networking sites such as Facebook are popular avenues of social discourse among adolescents and young adults, allowing for communication through photographs, videos, and chat features. These websites are also emerging as portals for health-centered support groups, bringing together people with common medical conditions. Adolescents with tracheostomies represent a special and vulnerable patient population. Our aim was to determine whether this particular group of patients found Facebook to be a suitable environment in which to network with other users with tracheostomies. We used our institution's tracheostomy database to obtain a list of all patients between ages of 11-18. We identified 33 patients in this category, and completed a chart review to determine their medical diagnoses as well as age at trach placement. We determined that of these 33 patients, 24 had severe neurocognitive delays that would render them unable to participate in the study. We contacted the remaining nine subjects and obtained appropriate consent for their participation in the study. Of the nine subjects with tracheostomies who completed our survey, four were actively involved with the Facebook community. Two of the four subjects regularly connected with people that they had not met in person, and all four subjects shared the fact that they had a tracheostomy with the Facebook community. Three of the four subjects posted pictures of themselves with their trach sites visible. Finally, three of the four subjects stated that they met and communicated with other Facebook members with tracheostomies. Social networking sites such as Facebook appear to offer an appropriate avenue for adolescents with tracheostomies to network with other users with tracheostomies. Further studies are warranted to assess the reach and social impact of these networking sites as portals of health-centered support groups, however, social networking sites and the cyberspace community may be a promising source of

    Full Text Available Every economy of an advanced nation relies on information systems and interconnected networks, thus in order to ensure the prosperity of a nation, making cyberspace a secure place becomes as crucial as securing society. Cyber security means ensuring the safety of this cyberspace from threats which can take different forms, such as stealing secret information from national companies and government institutions, attacking infrastructure vital for the functioning of the nation or attacking the privacy of the single citizen. The critical information infrastructure (CII represents the indispensable "nervous system", that allow modern societies to work and live. Besides, without it, there would be no distribution of energy, no services like banking or finance, no air traffic control and so on. But at the same time, in the development process of CII, security was never considered a top priority and for this reason they are subject to a high risk in relation to the organized crime.

    The main goal of a cyberspace environment is to support decision makers with relevant information on time for operational use. Cyberspace environments depend on geospatial data including terrestrial, aerial/UAV, satellite and other multi-sensor data obtained in electro-optical and other imaging domains. Despite advances in automated geospatial image processing, the "human in the loop" is still necessary because current applications depend upon complex algorithms and adequate classification rules that can only be provided by skilled geospatial professionals. Signals extracted from humans may become an element of a cyberspace system. This paper describes research experiments on integrating an EEG device within geospatial technology.

    Full Text Available Abstract The Cri du Chat syndrome (CdCS is a genetic disease resulting from a deletion of variable size occurring on the short arm of chromosome 5 (5p-. The incidence ranges from 1:15,000 to 1:50,000 live-born infants. The main clinical features are a high-pitched monochromatic cry, microcephaly, broad nasal bridge, epicanthal folds, micrognathia, abnormal dermatoglyphics, and severe psychomotor and mental retardation. Malformations, although not very frequent, may be present: cardiac, neurological and renal abnormalities, preauricular tags, syndactyly, hypospadias, and cryptorchidism. Molecular cytogenetic analysis has allowed a cytogenetic and phenotypic map of 5p to be defined, even if results from the studies reported up to now are not completely in agreement. Genotype-phenotype correlation studies showed a clinical and cytogenetic variability. The identification of phenotypic subsets associated with a specific size and type of deletion is of diagnostic and prognostic relevance. Specific growth and psychomotor development charts have been established. Two genes, Semaphorin F (SEMAF and δ-catenin (CTNND2, which have been mapped to the "critical regions", are potentially involved in cerebral development and their deletion may be associated with mental retardation in CdCS patients. Deletion of the telomerase reverse transcriptase (hTERT gene, localised to 5p15.33, could contribute to the phenotypic changes in CdCS. The critical regions were recently refined by using array comparative genomic hybridisation. The cat-like cry critical region was further narrowed using quantitative polymerase chain reaction (PCR and three candidate genes were characterised in this region. The diagnosis is based on typical clinical manifestations. Karyotype analysis and, in doubtful cases, FISH analysis will confirm the diagnosis. There is no specific therapy for CdCS but early rehabilitative and educational interventions improve the prognosis and considerable

  8. Modelling Hegemonic Power Transition in Cyberspace

    Directory of Open Access Journals (Sweden)

    Dmitry Brizhinev

    2018-01-01

    Full Text Available Cyberspace is the newest domain of conflict and cooperation between states. In cyberspace, as in all other domains, land, sea, air, and space, these interactions often lead to the emergence of hegemons which are characterised by their predominant influence over global world order and all other states. We examined the emergence and collapse of hegemons in a modelled cyberspace world through the notions of power transition and power diffusion. We used Repast Simphony to construct a simple agent-based model (ABM of a system of states interacting both competitively and cooperatively in this world. Our simple model parsimoniously captures the character of the real international system of states through simple parameters of wealth and power determining the outcome of attack or cooperation amongst pairwise interacting states. We found hegemons of global world order emerged in cyberspace as they do in the other traditional domains from models with these few parameters. And we found that hegemons, contrary to traditional understanding, are not exceptional states but merely occupy the tail of a continuous distribution of power and lifetimes. We also found that hegemony in the system depends on two perhaps unexpected parameters: the difficulty of acquiring power as wealth increases and the amount of cooperation between states. And as a consequence, we argue that cyberspace, as a power-diffuse domain where cooperation is easier than elsewhere, is less suited to the kind of hegemony we see in the traditional domains of state interaction.

    Directory of Open Access Journals (Sweden)

    Lars Løvlie

    2005-01-01

    Full Text Available In this essay I argue against the suggestion that cyberspace is afloatwith “disembodied subjectivities”, and for the idea that we humansconfigure the Internet according to our bodily existence. The situat-edness, orientedness and rhythm of our perceptions and actionscarry over from the real to the virtual world, making them oneexperiential world. We do not, then, leave the body behind when weenter cyberspace. This topological perspective may not only explainwhy we find the Windows interface pleasant and easy to use. It alsoilluminates how bodily experience orders the world in terms of thebasic directions front–back, right–left, up–down and over–under,and how it structures practical everyday life. Classical Bildung nur-tured the expressivist idea of an independent mind in its free self-creation. Topology, on the other hand, wants us to think in terms ofbody-minds, and suggests that even a Cyberbildung begins as aneducation of the flesh.

    Chisholm, June F

    2006-11-01

    Children and adolescents today are the first generation raised in a society in which technological literacy is essential for effective citizenship in the 21st century. With many more youth using digital technologies for educational and recreational purposes, there has been an increase in social problems in cyberspace, exposing them to different forms of cyberviolence. This article gives an overview of the developments in cyberspace, describes different types of cyberviolence, and focuses on cyberbullying among girls and adolescent females as both victims and perpetrators of cyberbullying. At-risk online activities among girls and adolescent females as well as strategies to promote cybersafety are presented. Current research and future directions for research are reviewed.

    Web 1.0 never left. It's just a term that refers to cyberspace before 2002. People mark the shift from Web 1.0 to 2.0 with the dramatic collapse of Web-based companies whose phenomenal growth was based on the profit potential of a new customer: the Internet user.

    Information from monitored systems is displayed in three dimensional cyberspace representations defining a virtual universe having three dimensions. Fixed and dynamic data parameter outputs from the monitored systems are visually represented as graphic objects that are positioned in the virtual universe based on relationships to the system and to the data parameter categories. Attributes and values of the data parameters are indicated by manipulating properties of the graphic object such as position, color, shape, and motion.

    2017-10-01

    Full Text Available The aim of this study was to investigate media literacy and information behavior in cyberspace. This was a review and library research based study. With the advent of the digital age and the increasing spread of the World Wide Web, popularity and general acceptance of virtual social networks in the world today, the need to examine media literacy and information behavior in human life is important. Approach to media literacy which is the subset of information literacy in cyberspace has become necessary and obvious. As an individual, higher level of literacy can lead to choosing better content and search for information to find useful content. By assessing the theoretical basis and different approaches in a virtual environment, it can be concluded that having literacy skills and information behavior, the period of time spent in cyberspace and the number of readers have increased, leading to the ability to criticize and interpret the social, political and economic information and identify useful information. Consequently, by acquiring new technologies and increasing the adaptability in viewpoints and improving skills within researchers, the context for developing new ideas will be provided.

  18. Perfume formulation: words and chats.

    Science.gov (United States)

    Ellena, Céline

    2008-06-01

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

  19. Sexual self-disclosure in Cyberspace among Taiwanese adolescents: gender differences and the interplay of Cyberspace and real life.

    Science.gov (United States)

    Chiou, Wen-Bin; Wan, Chin-Sheng

    2006-02-01

    This study explored adolescents' sexual self-disclosure in real life and cyberspace, as well as gender differences of sexual self-disclosure in cyberspace. There were 115 male and 92 female adolescents who participated in this pretest and posttest survey. In general, the depth of sexual self-disclosure in real life was greater than in cyberspace, but the breadth of sexual selfdisclosure in both real life and cyberspace was equivalent. The cross-lagged panel analysis indicated that adolescents who were willing to self-disclose sexual topics in real life also selfdisclosed them more in cyberspace, and vice versa. Furthermore, sexual self-disclosure in both disclosing environments was mutually predicted by each other. The findings also indicated that cyberspace might not be a substitute channel of compensatory gratification for sexual self-disclosure in real life. As for gender differences, the breadth and depth of sexual self-disclosure in male adolescents were greater than in female adolescents, in both real life and cyberspace. Male adolescents tend to be more active in Internet sexuality than females. However, female adolescents' sexual emancipation in cyberspace is not evident in Taiwan. Possible reasons, implications, and limitations of the findings are discussed.

    Today, the Internet has become a source of information that no country or company can forgo. It is not only used to communicate or entertain, but most importantly to operate utilities and public services such as banking or air traffic. As the reliance on computer networks across societies and economies keeps growing, so do security risks in cyberspace - referred to as ""cybersecurity."" Cybersecurity means protecting information and control systems from those who seek to compromise them. It also involves actors, both malicious or protective, policies and their societal consequences.

    A service access control model in cyberspace is proposed, which provides a generalized and effective mechanism of security management with some items constraint specifications. These constraint specifications are organized to form a construction, and an enact process is proposed to make it scalable and flexible to meet the need of diversified service application systems in cyberspace. The model of this paper erases the downward information flow by extended rules of read/write, which is the breakthrough of the limitations when applying the standard role-based access control in cyberspace.

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

    Directory of Open Access Journals (Sweden)

    Murilo Canella

    2012-05-01

    Full Text Available This study attempts to draw a picture of “liquid-modern” society regarding the extreme relationship exchange and neologism existing among the association forms created from the “solid modernity”. It tries to demonstrate the correlation between the fragmentation of tradition and the emergency for new values which, in its direct confrontation, brought to the humanity an era of new meanings and ongoing processes. From this concept derives the duality between “global” and “local”, submitted to economic, political, social and cultural processes, which in a closer examination shows the confl uence of latent crisis regarding the individual identity, even more oriented by global processes, inserted in an also global and virtual space, cyberspace. It follows, however, the problematic about the loss of individuals humanity by the impersonal logic of consumerism and its infl uence on individual thought.

    2009-04-01

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

  11. Makt og avmakt i cyberspace: hvordan styre det digitale rom?

    Directory of Open Access Journals (Sweden)

    Lilly Pijnenburg Muller

    2016-12-01

    Full Text Available Et sikkert cyberspace er nødvendig for en fungerende samfunnsstruktur, økonomisk, politisk og sosialt. Med samfunnets økende avhengighet av cyberspace for å kunne fungere normalt, har sikringen av cyberspace blitt stadig viktigere. For å løse sikkerhetsutfordringene knyttet til utviklingen av cyberspace har stater søkt støtte fra private aktører gjennom såkalte multistakeholder-initiativer. Med slike initiativer mener man en åpen form for samarbeid mellom interessenter, basert på en idé om likeverdige partnere. Stater iverksetter slike initiativer ut fra en tanke om at et samarbeid mellom private og offentlige aktører gir den beste formen for styring og sikring av aktiviteter i cyberspace. Implementeringen foregår imidlertid uten at de nødvendige forutsetningene for at en slik styringsform skal fungere er til stede. Selv om mange i dagens akademiske debatt stiller spørsmål ved om disse initiativene fungerer, er det få som har stilt spørsmål ved hvordan cybersikkerhet kan utøves i praksis. Dette fører til at man overser det sentrale spørsmålet om hvordan maktdynamikken mellom offentlig og privat sektor fungerer med henblikk på sikkerhet i cyberspace. Denne artikkelen diskuterer hvorvidt multistakeholder-initiativene faktisk fungerer som en kontroll- og styringsmekanisme i cyberspace. Ved å se nærmere på offentlig-privat samarbeid om cybersikkerhet i Norge er hensikten å gi en bedre forståelse av årsakene til at multistakeholder-initiativer ofte ikke fungerer i praksis.

We conducted this study to identify the health system critical considerations on core issues, involving the development of medical education on cyberspace. In order to conduct this study, we observed the steps of a critical literature review, combined with the 'Four-phase method' adopted by Carnwell and Daly. We focused on particular literature on health and cyber system functions; it was associated with systemic approach. We developed a six-level taxonomy, Cyber level, Governance level, Ministerial level, Organizational level, Program level and Performance level, as a key solution that can be applied for the success of medical education on cyberspace. The results were summarized and appraised in more details. Medical education on cyberspace is a complex interdisciplinary system. It is important that all aspects of the health systems be involved as integral to the development of cyber based medical education; without this convergence, we will be confused by the decisions made by others within the system. Health system should also communicate with those external sectors that are critical to achieving better learning on cyberspace. Integrated planning, governance and management of medical education in cyberspace are pivotal elements for the promotion.

  13. Von Neuromancer zu Second Life. Raumsimulationen im Cyberspace

    Directory of Open Access Journals (Sweden)

    Krämer, Steffen

    2011-07-01

    Full Text Available In his novel Neuromancer, first published in 1984, the US-american author William Gibson coined the term cyberspace for the virtual reality generated by computers. On the basis of an etymological analysis this term can be interpreted as the traditional relation between helmsman and space. In the medium of sci-fi-literature and sci-fi-film this phenomenon of cyberspace changed rapidly between 1980 and today. In early examples, for instance in the film Tron produced in 1982, the virtual figures act in a disintegrated space without any destination or orientation. In later examples, for instance in the film Matrix produced in 1999, the cyberspace becomes a substitute world for a dark, chaotic or destructive vision of reality. Contemporary forms of cyberspace, as visualized in the 3D-online-city Second Life, are in contrast used for financial activities and symbolize the hard world of economic policy. This development of cyberspace can be seen either as an evolutionary process or a dichotomy primary defined by different facets of space simulation in virtual reality.

    Wars previously being executed at land and sea have also become applicable in air and space due to the advancements of aircraft and satellite systems. Rapid improvements in information technologies have triggered the concept of cyberspace which is considered as the fifth dimension of war. While transferring information quickly from physical area to electronic/digital area, cyberspace has caused to emerge a lot of threats and methods like cyber-attack, cyber-crime, cyber war which are spreading too rapidly. Individuals, institutions and establishments have begun to take their own cyber security precautions to cope with these threats. This study gives information about the concepts and advances on cyberspace in order to raise comprehensive awareness. The study also focuses on the effects of these improvements in the battlefield, and analyzes them.

  15. Emotional persistence in online chatting communities

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

    2012-05-01

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

Children begin to learn ethical values right from birth through?families?and?religious?institution.?They?are?considered?as?primary?sources?for?a?childís?ethical?education?while?schools have the responsibility to teach and reinforce some moral values. New technologies bring about the need to interpret old values in new ways, but also may call for the creation of new codes of conduct when new actions are made possible with the use of technology. Children can quickly identify whether the behavior is right or wrong in real world but when students use virtual world behavior may not be as easily judged to be right or wrong. This study attempts to show the prevailing misconception thecyber ethics among students. This paper examines basis ethical issues when students have had to make ethical decisions. The study will qualitatively explore the level of understanding of teachers concerns and role in bringing in an ethical behavior on students on the Internet. If a student encounters unsafe behavior on the Internet, the student will be able to behave and act appropriately.

    2011-01-01

    Online chatting is an important component of improving interpersonal relationships online, but it may reduce participants' communication time with family members. We conducted a study of the relationship between participants' intent to engage in online chatting and three dimensions of loneliness: social, familial, and romantic. This study was designed to show the effect of online chatting on each of these three dimensions of loneliness. The participants in the study were 709 students at two universities in Taiwan who were classified on the basis of whether or not they had ever engaged in online chatting. Of the participants, 651 (91.82%) fully completed the questionnaires that served as the study instruments and were included in data analysis. The study found that individuals who had participated in online chatting exhibited greater familial loneliness than those who had not because the time spent in online chatting reduced the time spent in familial relationships. Social loneliness was related to the quality of Internet relationships rather than to the time spent online. Individuals who participated in online chatting had less romantic loneliness because of a greater ease of maintaining romantic relationships online. We conclude that online chatting can reduce social loneliness through high-quality Internet relationships but may exacerbate familial loneliness.

  15. The Flostation - an Immersive Cyberspace System

    Science.gov (United States)

    Park, Brian

    2006-01-01

    A flostation is a computer-controlled apparatus that, along with one or more computer(s) and other computer-controlled equipment, is part of an immersive cyberspace system. The system is said to be immersive in two senses of the word: (1) It supports the body in a modified form neutral posture experienced in zero gravity and (2) it is equipped with computer-controlled display equipment that helps to give the occupant of the chair a feeling of immersion in an environment that the system is designed to simulate. Neutral immersion was conceived during the Gemini program as a means of training astronauts for working in a zerogravity environment. Current derivatives include neutral-buoyancy tanks and the KC-135 airplane, each of which mimics the effects of zero gravity. While these have performed well in simulating the shorter-duration flights typical of the space program to date, a training device that can take astronauts to the next level will be needed for simulating longer-duration flights such as that of the International Space Station. The flostation is expected to satisfy this need. The flostation could also be adapted and replicated for use in commercial ventures ranging from home entertainment to medical treatment. The use of neutral immersion in the flostation enables the occupant to recline in an optimal posture of rest and meditation. This posture, combines savasana (known to practitioners of yoga) and a modified form of the neutral posture assumed by astronauts in outer space. As the occupant relaxes, awareness of the physical body is reduced. The neutral body posture, which can be maintained for hours without discomfort, is extended to the eyes, ears, and hands. The occupant can be surrounded with a full-field-of-view visual display and nearphone sound, and can be stimulated with full-body vibration and motion cueing. Once fully immersed, the occupant can use neutral hand controllers (that is, hand-posture sensors) to control various aspects of the

Before the research three hypotheses were proposed: 1 MRU students are more enterprising than the statistical resident of Lithuania; 2 student entrepreneurship education in Management and Administration studies is inadequate; 3 students need specialized knowledge of entrepreneurship in cyberspace. After the analysis of gathered data from students all three hypotheses were confirmed: students are more entrepreneurial then the general population of Lithuania, entrepreneurial education at the university is insufficient and there is a need among students for specialized knowledge in the field of e-business. Follow-up study of the negative dynamics of student entrepreneurship should be carried

    The cri-du-chat syndrome is a rare genetic disorder caused by deletions in the short arm of chromosome 5. It presents with a distinctive catlike high-pitched cry, psychomotor delays, microcephaly, craniofacial abnormalities, and, in many cases, ocular findings. We report the first child with cri-du-chat and the findings of unilateral corneal staphyloma due to Peters anomaly and retinal dysplasia.

  16. Room Acoustics

    Science.gov (United States)

    Kuttruff, Heinrich; Mommertz, Eckard

    The traditional task of room acoustics is to create or formulate conditions which ensure the best possible propagation of sound in a room from a sound source to a listener. Thus, objects of room acoustics are in particular assembly halls of all kinds, such as auditoria and lecture halls, conference rooms, theaters, concert halls or churches. Already at this point, it has to be pointed out that these conditions essentially depend on the question if speech or music should be transmitted; in the first case, the criterion for transmission quality is good speech intelligibility, in the other case, however, the success of room-acoustical efforts depends on other factors that cannot be quantified that easily, not least it also depends on the hearing habits of the listeners. In any case, absolutely "good acoustics" of a room do not exist.

    A new syndrome was identified in 1963, when Lejeune et al. reported a genetic disease resulting from a partial or total deletion on the short arm of chromosome 5 (5p-) and named it the cri du chat syndrome (CdCS). This term makes reference to the main clinical feature of the syndrome, a high-pitched monochromatic cat-like crying, that usually disappears in the first years of life. CdCS is one of the most common chromosomal deletion syndromes in humans, with an incidence of 1:15.000-1:50.000 live-births. Our purpose was to review different aspects of this syndrome (concept, epidemiology, aetiology, clinical features, diagnostic methods and prognosis) emphasizing both: the breakthrough in this field introduced by new cytogenetic and molecular techniques, and the orofacial manifestations most frequently reported. The main orofacial anomalies registered were mandibular microretrognathia, high palate but rarely cleft, variable malocclusion (frequently anterior open-bite), enamel hypoplasia, poor oral hygiene, generalized chronic periodontitis, and retardation of tooth eruption, although there is not enough evidence to support any clear association between these pathologies and the CdCS.

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

    Cri du chat syndrome is a genetic alteration associated with some oral pathologies. However, it has not been described previously any clinical relationship between the periodontal disease and the syndrome. The purpose of this comparative study was to compare periodontopathogenic flora in a group with Cri du chat syndrome and another without the síndrome, to assess a potential microbiological predisposition to suffer a periodontitis. The study compared nineteen subjects with Cri du chat Syndrome with a control group of nineteen patients without it. All patients were clinically evaluated by periodontal probing, valuing the pocket depth, the clinical attachmente level and bleeding on probing. There were no significant differences between both groups. Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Prevotella intermedia, Tannerella forsythia and Treponema denticola were detected by multiplex-PCR using 16S rDNA (microIDENT). When A. actinomycetemcomitans, P. gingivalis, P. intermedia and T. denticola were compared, no statistically significant differences were found between the two groups (p>0.05). The value of T. forsythia was significantly higher for Cri du chat syndrome (31.6%) than for the control group (5.3%). The odds ratio for T. forsythia was 8.3. In the present study T. forsythia is associated with Cri du chat syndrome subjects and not with healthy subjects.

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

  4. Meatspace is Cyberspace: The Pynchonian Posthuman in Bleeding Edge

    Directory of Open Access Journals (Sweden)

    Jason Siegel

    2016-06-01

    Full Text Available This article examines Thomas Pynchon’s indirect critique of utopian posthumanism in 'Bleeding Edge' by analyzing the deleterious effects that an emerging Internet culture has on the novel’s characters. By seeping into every aspect of their lives, embedding itself in their minds, and becoming a prosthetic consciousness, the Internet has transformed the characters into posthumans and altered their subject positions within a technological global capitalist culture. Contrasting the novel’s take on the posthuman with the posthuman theories of Donna Harraway, N. Katherine Hayles, Robert Pepperell, Rosi Braidotti, David Roden and Seb Franklin, I argue that, while the dominant utopian strain in posthuman theory imagines the advent of posthumanism as an opportunity for liberation from the sexism, racism, and colonial oppression that are enabled by the positing of the classical humanist subject, Pynchon demonstrates that because the Internet technology that brought about the posthuman condition is controlled by governments and corporations, it has become just one more lost chance at freedom that was converted into an instrument of increased control and surveillance. Reading 'Bleeding Edge' against William Gibson’s prototypical posthuman novel Neuromancer, I also contend that while Gibson, despite challenging the ontological primacy of meatspace over cyberspace, keeps the two realms separate, Pynchon, who borrows Gibson’s terms, shows that cyberspace has already merged with meatspace. As a result, Maxine Tarnow, the protagonist of 'Bleeding Edge', has nowhere to run in her attempt to find a provisional refuge for herself and her family.

  5. Electronic Market and Business: Cyberspace vs. Electronic Environment

    Directory of Open Access Journals (Sweden)

    Deniss Ščeulovs

    2013-12-01

    Full Text Available The authors of the article analyze the concept "electronic environment". Having studied a range of academic literature sources and other sources, the authors of the article have drawn a conclusion that the academic writings do not provide a definition of "electronic environment". Furthermore, the various opinions among specialists regarding this concept often differ. Meanwhile, there are several explanations of the term "cyberspace" overlapping the concept of "electronic environment", and these terms are often believed to be synonyms. To understand what the term "electronic environment" means and to properly and correctly employ this concept in entrepreneurship, the authors have performed a lexicographic analysis of this concept by comparing reciprocal concepts. As a result of the research, the authors propose their view on what, in their opinion, "electronic environment" is and what its connection to the concept "cyberspace" is. The topicality of the article lies in the fact that often entrepreneurs and specialists of public and other institutions, when using these terms, imply completely different concepts. It can lead to misunderstanding and misinterpreting the information, as well as to encumbering the understanding of tasks, problems, etc.

    2017-08-01

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

  15. Security-by-Experiment: Lessons from Responsible Deployment in Cyberspace.

    Science.gov (United States)

    2016-06-01

    Conceiving new technologies as social experiments is a means to discuss responsible deployment of technologies that may have unknown and potentially harmful side-effects. Thus far, the uncertain outcomes addressed in the paradigm of new technologies as social experiments have been mostly safety-related, meaning that potential harm is caused by the design plus accidental events in the environment. In some domains, such as cyberspace, adversarial agents (attackers) may be at least as important when it comes to undesirable effects of deployed technologies. In such cases, conditions for responsible experimentation may need to be implemented differently, as attackers behave strategically rather than probabilistically. In this contribution, we outline how adversarial aspects are already taken into account in technology deployment in the field of cyber security, and what the paradigm of new technologies as social experiments can learn from this. In particular, we show the importance of adversarial roles in social experiments with new technologies.

    In terms of health and healthcare cyberspace and virtual reality can be used differently and for different purposes and consequently create different outcomes. The three main areas which we shall discuss here are: 1) cyberspace as provider of health information and self-help resources, since the anonymity cyberspace provides is particularly important in the highly stigmatized field of psychiatry where a large number of people never seek professional help, which in turn negatively affects not only the person in question, but the family and ultimately the society (work efficiency, disability-adjusted life year - DALY, etc.), 2) cyberspace and virtual reality (VR) as cause of psychopathology, starting from violent behaviour, to addictive behaviour and other, 3) and finally cyberspace and VR as providers of efficient professional therapy in the field of psychiatry.

    Rana, Pradeep

    With the increasing use of mobile devices everywhere in the world, there is a lack of social interaction between people. The objective of this thesis project is to create a location based chat application, which will help users to interact with other people around them. It will provide an opportunity to meet people when someone visits a new place. The app will use GPS coordinates of the user and will show him a list of other users based on his location. The user can then choose any of the other users from the list and start chatting with them. This app will consist of a frontend and backend. The frontend will be an iOS application and the backend will be a PHP/MYSQL server.

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

    To find the length and location of the deletions in the short arm of chromosome 5 in one case of Cri du Chat syndrome using oligo array comparative genomic hybridization. Metaphase chromosomes were prepared from peripheral blood lymphocyte cultures using standard cytogenetic protocols. Chromosomal analysis was done in G-banded metaphases. Oligo array comparative genomic hybridization and fluorescence in situ hybridization were performed by the commercially available kits. Oligonucleotide array comparative genomic hybridization (CGH) analysis revealed a 23.263 Mb deletion at region 5p14.2-->qter, combined with a duplication of 14.602 Mb in size in the area 12p13.1-->pter. Chromosomal aberrations were confirmed by fluorescence in situ hybridization. The male neonate with Cri du Chat syndrome had an unbalanced translocation which was inherited from his father who was a balanced carrier with a karyotype 46, XY, t (5; 12) (p14.2; p13.1). This report shows the clinical utility of the oligonucleotide array in the detection of submicroscopic chromosomal aberrations, thus improving the molecular diagnosis of Cri du Chat syndrome.

    1999-01-01

    NASA is considering the development of a Cooperative Human-Adaptive Traffic Simulation (CHATS), to examine and evaluate performance of the National Airspace System (NAS) as the aviation community moves toward free flight. CHATS will be specifically oriented toward simulating strategic decision-making by airspace users and by the service provider s traffic management personnel, within the context of different airspace and rules assumptions. It will use human teams to represent these interests and make decisions, and will rely on computer modeling and simulation to calculate the impacts of these decisions. The simulation objectives will be to examine: 1. evolution of airspace users and the service provider s strategies, through adaptation to new operational environments; 2. air carriers competitive and cooperative behavior; 3. expected benefits to airspace users and the service provider as compared to the current NAS; 4. operational limitations of free flight concepts due to congestion and safety concerns. This paper describes an operational concept for CHATS, and presents a high-level functional design which would utilize a combination of existing and new models and simulation capabilities.

  11. Collective emotion dynamics in chats with agents, moderators and Bots

    M. Šuvakov

    2014-09-01

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

    Full Text Available Online-supported teaching and learning is a technological innovation in education that integrates face-to-face teaching in plenary lectures, with an online component using a learning management system. This extends opportunities to students to interact with one another via online chats in the process of transacting their learning. There is a need to understand how South African students experience these technologies, where many students encounter them for the first time at higher education level. We are yet to understand variations in students' experiences of online support and how it has influenced their learning. This article explores students' experiences of learning using online chats in Business Management Education. The qualitative component of this mixed-methods research draws on the tenets of phenomenography. Fifteen participants from a Business Management Education class of 156 students enrolled in a Bachelor of Education programme were sampled using pheno-menographic approach. Qualitative data sources included personal reflective journals, focus group discussions and individual interviews, and questionnaires were circulated to the respondents. A quantitative component was subsequently implemented to validate the qualitative findings. Analysis of the data revealed that participants viewed online chats as learning contexts in qualitatively different ways.

    Autism spectrum disorders (ASDs) often go undetected in toddlers. The Modified Checklist for Autism in Toddlers (M-CHAT) With Follow-up Interview (M-CHAT/F) has been shown to improve detection and reduce over-referral. However, there is little evidence supporting the administration of the interview by a primary care pediatrician (PCP) during typical checkups. The goal of this study was to evaluate the feasibility, validity, and reliability of the M-CHAT/F by PCPs with online prompts at the time of a positive M-CHAT screen. Forty-seven PCPs from 22 clinics completed 197 M-CHAT/Fs triggered by positive M-CHAT screens via the same secure Web-based platform that parents used to complete M-CHATs before an 18- or 24-month well-child visit. A second M-CHAT/F was administered live or by telephone by trained research assistants (RAs) at the Kennedy Krieger Institute Center for Autism and Related Disorders. The Autism Diagnostic Observation Schedule, Second Edition, and the Mullen Scales of Early Learning were administered as criterion measures. Measures of agreement between PCPs and RAs were calculated, and measures of test performance compared. There was 86.6% agreement between PCPs and RAs, with a Cohen's κ of 0.72. Comparison of sensitivity, specificity, positive predictive value (PPV), and overall accuracy for M-CHAT/F between PCPs and RAs showed significant equivalence for all measures. Use of the M-CHAT/F by PCPs resulted in significant improvement in PPV compared with the M-CHAT alone. Minimally trained PCPs can administer the M-CHAT/F reliably and efficiently during regular well-child visits, increasing PPV without compromising detection.

    Full Text Available Abstract This paper uses the framework of the Copenhagen School to understand the process of securitization of cyberspace, exploring how something in such sphere becomes a threat. Seeking to contribute to the debate, this study analyses the securitization discourses of Brazil and of the United States from Hansen and Nissenbaum's (2009 theorization about the existence of a specific sector for cybersecurity. To comprehend the securitization of cyberspace in these terms allows not only to identify distinct levels of securitization, but also to capture the dynamics of cyber threats, distinguishing them from those existent in other sectors, as well as to trace distinctions between tendencies of securitization and militarization.

    Full Text Available In this paper we report findings of a multidisciplinary study of online participation by culturally diverse participants in a distance adult education course offered in Canada and examine in detail three of the study's findings. First, we explore both the historical and cultural origins of "cyberculture values" as manifested in our findings, using the notions of explicit and implicit enforcement of those values and challenging the assumption that cyberspace is a culture free zone. Second, we examine the notion of cultural gaps between participants in the course and the potential consequences for online communication successes and difficulties. Third, the analysis describes variations in participation frequency as a function of broad cultural groupings in our data. We identify the need for additional research, primarily in the form of larger scale comparisons across cultural groups of patterns of participation and interaction, but also in the form of case studies that can be submitted to microanalyses of the form as well as the content of communicator's participation and interaction online.

  1. Consent in cyberspace: Internet-based research involving young people.

    Science.gov (United States)

    2009-12-01

    Social networking sites such as MySpace and virtual communities such as on-line support groups can be a rich source of data for researchers. These sites can be an effective way of reaching and researching young people in order to address their particular health needs. Internet-based research is also potentially risky and exploitative. There is some guidance for conducting research online, but there are no detailed or universally accepted ethics guidelines for research of webspaces such as MySpace or virtual communities in which young people participate. One question that arises is--If MySpace is a public webspace, can research be done without consent? In this paper I investigate ethical issues surrounding young people's consent in cyber research. I identify issues that help determine whether consent is needed, offer suggestions for dealing with consent in cyberspace and add my voice to the call for a resource of case studies--indispensible in the development of guidelines and the education of researchers and research ethics committees.

According to the IAEA, the use of computers and other digital electronic equipment in physical protection systems at nuclear facilities, as well as in facility safety systems, instrumentation, information processing and communication, ''continues to grow and presents an ever more likely target for cyber-attack''. The international nuclear industry is right to take heed of ever-evolving security threats, deal with them accordingly, and be as open and transparent as security allows about what is being done, which will reassure the general public. However, the potential menace of cyberspace should not be allowed to become such a distraction that it gives those who are ideologically opposed to nuclear another stick with which to beat the industry.

    2015-01-01

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

    2018-03-01

    The current study examined the influences of stressful life events and WeChat addiction on life satisfaction, and investigated the mediating role of WeChat addiction on the relationship between the two research variables. A total of 463 undergraduates completed self-reported scales for stressful life events, WeChat addiction, and life satisfaction. Structural equation modeling was used to analyze the questionnaire data. The results showed the suppressing effect of WeChat addiction on the negative impact of stressful life events on life satisfaction. Stressful life events affect life satisfaction both directly and indirectly. Stressful life events are positively associated with WeChat addiction, which exerts positive impact on life satisfaction. The contributions of the findings are discussed.

    Hallett, Jonathan; Brown, Graham; Maycock, Bruce; Langdon, Patricia

    2007-01-01

    This article is a case study of an Internet chat room outreach project in Perth, Western Australia. The CyberReach project sought to adapt current peer based health promotion outreach, training and supervision frameworks to an online outreach setting in a way that was effective and supported by the online community. It targeted marginalised groups to trial the provision of online mental and sexual health promotion incorporating a participatory action research model into its development and implementation. Three 6-week trial periods were conducted and significant changes were made in response to changes in the online environment and to improve sustainability and effectiveness of the protocols. Four themes arose from CyberReach's experience: online group processes are unique due to the creation of extensive personal networks and occurrence of disclosure without face-to-face contact across potentially large geographic barriers; flexibility is required to adapt to technological changes and online community flux; enforcing boundaries and delineating peer education from therapeutic support can be challenging when only using text-based communication; and Internet outreach can be time intensive with small returns in actual community engagement and constant technological up-skilling of staff may be required. Based on the project's experiences we offer the following recommendations when planning similar Internet outreach strategies: Funding and planning groups need to be aware that the Internet environment is constantly changing and planning and funding arrangements need to reflect a capacity to remain flexible; Programs need to be firmly connected to the communities they are outreaching therefore a peer-based education component is strongly encouraged; Careful consideration should be taken regarding data collection so that the environment and the individuals within are respected; Further research needs to be conducted to understand the styles and approaches of different

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

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

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

    2017-12-01

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

    Full Text Available Along with the development of data storage technology which previously using relational concept began to change to the non-relational concept or sometimes referred to as the term NoSQL technology. Data storage in NoSQL is no longer based on the relations between tables but using another methods, one of them is document-oriented. This method was applied specifically in MongoDB. This concept brings new hope because oftheir superiority that can handle very large data with promising performance and is perfect for agile system development. The purpose of this research was to measure the performance NoSQL, especially MongoDB with implemented it in a Android based mobile chat application. This research uses three methods, analysis method including literature study, analysis of similar application, questionnaires, design method using Agile SofwareDevelopment, and evaluation method including eight golden rules, analysis of similar application, questionnaires, and interview. The results of this research is a mobile chat application that uses MongoDB as the data storage technology. Through this research can be drawn the conclusion that NoSQL technology implementation, MongoDB, give special advantages like lighter data storage and faster data access.

  12. Twitter Chats as Third Places: Conceptualizing a Digital Gathering Site

    Directory of Open Access Journals (Sweden)

    John A. McArthur

    2016-08-01

    Full Text Available Social media users can harness the interactivity and connectivity of social networking sites to create a sense of place in a digital environment. This article argues that regularly scheduled Twitter chats can function as digital third places, sites of online sociality that both mirror and deviate from physical gathering sites such as bars or clubs. Using Oldenburg’s eight characteristics of (built third places, this study examines how people collectively identify with others and collaborate in digital gathering sites. Through an investigation of 1 month of multiple, recurring Twitter chats, including over 3,100 tweets, a textual analysis explores Oldenburg’s characteristics of built third places in the context of these digital interactions. The findings add nuance to the application of Oldenburg’s themes in a networked media context and suggest that social networking sites offer the potential for continued thinking about the role of third places in developing connectivity online. Moreover, the findings suggest further opportunities for the study of space—both physical and digital—and the study of time as integral components of digitally mediated interpersonal connection.

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

    Directory of Open Access Journals (Sweden)

    Barbara O’Neill

    2018-02-01

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

    Cri du chat syndrome is an autosomal disorder. Because it affects few people in the population it is considered a rare disease, yet it is one of the most common autosomal chromosomal syndromes in humans. It entails pathognomonic alterations that affect the craniofacial and oral anatomy of patients. The aim of this study is to review these craniofacial and oral abnormalities in patients with Cri du chat syndrome. The PubMed Medline database was searched using two different strategies. First, we used "Dentistry" and "Cri du chat" as keywords; second, we used "Cri du chat" and "craniofacial." Seven articles in which the main orofacial and cranio-skeletal characteristics of patients with Cri du chat syndrome were described were selected according to the inclusion and exclusion criteria. Cri du Chat syndrome entails pathognomonic characteristics in the craniofacial area (epicanthus, short philtrum, and wide nasal bridge), the oral area (mandibular retrognathism and anterior open bite) and the cranial region (alterations at the cranial base angle and a small upper airway). However, more studies on larger samples are needed to specify the orofacial and craniofacial characteristics of patients with Cri du chat syndrome more accurately. Clin.

    The Modified Checklist for Autism in Toddlers (M-CHAT) is a screening tool for autism spectrum disorders in the clinic. However, the follow-up questions in the M-CHAT are difficult to implement on a paper format. To compare the effectiveness of the M-CHAT on an electronic format versus paper format in an outpatient clinic setting. Methods. A prospective study used electronic M-CHAT on the iPad. A retrospective review of paper M-CHATs 6 months prior to implementation was used as the comparison group. A total of 176 participants completed the electronic M-CHAT format and 197 paper M-CHATs were retrospectively reviewed. The electronic format (3%) resulted in a significant difference in the frequency of children found to be at risk for autism compared with the paper version (11%); 99% of parents rated the experience as "good" or "excellent." The electronic format lowered both false at-risk screens and false not-at-risk screens and had higher parental satisfaction.

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

    Kristoffersen, Kristian E; Garmann, Nina Gram; Simonsen, Hanne Gram

    2014-10-01

    This article focuses on consonant productions by a group of children with cri du chat syndrome (CdCS) and examines how various aspects of these productions contribute to these children's overall intelligibility. Eight children and adolescents with CdCS participated in the study, and the following four questions were addressed: (1) What are the characteristic features of the consonant inventories of the subjects in terms of size and types of consonants; (2) how do the subjects render the consonant phonemes of the target language; (3) to what degree do the subjects produce target-like words; and (4) what is the relationship between consonant production and intelligibility? For the majority of our subjects, we found low proportions of correctly produced consonants, small consonant inventories with several recurrent types of deviant consonants, inaccuracy in realization of target phonemes and variable similarity to target words, all of which may contribute to reduced intelligibility.

    The cri du chat syndrome (CdCS) is a chromosomal deletion syndrome associated with a partial deletion of the short (p) arm of chromosome 5. We describe five children who were diagnosed to have CdCS by conventional cytogenetic analysis. The deletion was at 5p15 in four patients, whereas the fifth had a larger, more proximal deletion at 5p14. Fluorescence in situ hybridization (FISH) analysis confirmed the deletion of the CdCS critical region at 5p15.2. All five children had global developmental delay and dysmorphism with microcephaly. The other clinical features were variable. Since the clinical diagnosis of CdCS may not always be evident because of the phenotypic heterogeneity, cytogenetic analysis is necessary to establish the diagnosis and confirm that the deletion involves the CdCS critical region. This will enable early intervention which plays an important role in improving the outcome.

    Human movements in the real world and in cyberspace affect not only dynamical processes such as epidemic spreading and information diffusion but also social and economical activities such as urban planning and personalized recommendation in online shopping. Despite recent efforts in characterizing and modeling human behaviors in both the real and cyber worlds, the fundamental dynamics underlying human mobility have not been well understood. We develop a minimal, memory-based random walk model in limited space for reproducing, with a single parameter, the key statistical behaviors characterizing human movements in both cases. The model is validated using relatively big data from mobile phone and online commerce, suggesting memory-based random walk dynamics as the unified underpinning for human mobility, regardless of whether it occurs in the real world or in cyberspace.

    Understanding the dynamics of human movements is key to issues of significant current interest such as behavioral prediction, recommendation, and control of epidemic spreading. We collect and analyze big data sets of human movements in both cyberspace (through browsing of websites) and physical space (through mobile towers) and find a superlinear scaling relation between the mean frequency of visit and its fluctuation σ :σ ˜β with β ≈1.2 . The probability distribution of the visiting frequency is found to be a stretched exponential function. We develop a model incorporating two essential ingredients, preferential return and exploration, and show that these are necessary for generating the scaling relation extracted from real data. A striking finding is that human movements in cyberspace and physical space are strongly correlated, indicating a distinctive behavioral identifying characteristic and implying that the behaviors in one space can be used to predict those in the other.

  5. Illness and Internet empowerment: writing and reading breast cancer in cyberspace.

    2004-01-01

    The Internet is now a site where women with breast cancer both read and write about the illness, and in doing so negotiate identity and definitions of situation in disembodied space. Cyberspace has been imagined as a liberatory realm where women can transgress gender roles, invent selves and create new forms of knowledge. This study explores the personal web pages of women with breast cancer with an interest in exploring the issue of 'cyber-agency' or empowerment in cyberspace. I suggest here that women's web pages might offer potentially critical opportunities for women's knowledge-making in relation to what are often highly political aspects of the body, gender and illness. However, the Internet is not an inherently empowering technology, and it can be a medium for affirming norms of femininity, consumerism, individualism and other powerful social messages.

    Disciplines such as Internet Research, the Psychology of Cyberspace and the Social Psychology of Cyberplaces call for an epistemological reflection not merely on the universe of objects they deal with, but also, and perhaps especially, on the research settings used to investigate them. With this work, we intend to make a contribution to the debate on three issues: psychosocial interpretation of the new environments, the "mediated" nature of the researcher-setting-study object relationship, and cyberplaces as settings for mediated interaction research.

    Full Text Available Introduction: The interaction in cyberspace can be seen as a process of reciprocal information, in which the designer should indicate how else can act. In this process, the informational guy is not a passive agent, it is called the interpretation. Metacommunication leads the designer to worry about predicting the needs taking into account the vision of who this guy is, what he seeks in the interface and through. Objective: To analyze the interfaces as the designer Metacommunication in cyberspace for identify the contribution of Semiotic Engineering for the designer in the process of signification and representation interfaces. Methodology: To make the Document Analysis, used the categorical analysis technique, or a spin-off of Static signs, Dynamic and Metalinguistic of Theory of Semiotic Engineering, comparing them with the triadic division of signs Peirce (Icon, Index and Symbol in the selected corpus: National Library of Australia and the Library of Congress. Results: It was observed a greater concern of the designer of the US Library of Congress to use the metacommunication, because the designer has created more routes and directions to paths that anticipated the possible intentions of informational subjects in the quest for knowledge. Conclusions: The theory of Semiotic Engineering contributes to the Information Science in the search for better represent the knowledge to bring the concept of interface as Metacommunication designer for informational subject navigating in cyberspace, both interpreters minds and producers of knowledge.

    Full Text Available Internet penetration has created a revolutionary change in people's communication nowadays. By creating immaterial and elusive cyberspace, without borders and limits of communication a three-dimensional territorial concept has been transformed by globalizing social relations and reducing importance of regional or national dimensions. All situations taking place on the Internet also occur somewhere in the reality. Sometimes it is difficult to measure whether the events are random or unrelated to particular events. Technological progress offers new possibilities to change a user's real location either consciously or subconsciously. However, the law is highly territorial in nature. This article focuses on existing conflict of law rules under the EU law and reveals its weaknesses in relation to non-contractual obligations caused by the Internet. Therefore, the author observes core concepts of the applicable law by analyzing the legal notions and information technology concepts and assessing the suitability of regulation in cyberspace. The EU regulation, the doctrine of European and domestic authors as well as the EU case law have been examined. As a result, a number of conclusions have been drawn on the suitability of non-contractual relationships in cyberspace considering Rome II Regulation.

    Cri-du-chat is a chromosomal deletion syndrome characterized by partial deletion of the short arm of chromosome 5. The clinical symptoms include growth and mental retardation, microcephaly, hypertelorism, epicanthal folds, hyptonia, and a high-pitched monochromatic cry that is usually considered diagnostic for the syndrome. Recently, a correlation between clinical features and the extent of the chromosome 5 deletions has identified two regions of the short arm that appear to be critical for the abnormal development manifested in this syndrome. Loss of a small region in 5p15.2 correlates with all of the clinical features of cri-du-chat with the exception of the cat-like cry, which maps to 5p15.3. Here the authors report the construction of a YAC contig that spans the chromosomal region in 5p15.2 that plays a major role in the etiology of the cri-du-chat syndrome. YACs that span the 2-Mb cri-du-chat critical region have been identified and characterized. This YAC contig lays the groundwork for the construction of a transcriptional map of this region and the eventual identification of genes involved in the clinical features associated with the cri-du-chat syndrome. It also provides a new diagnostic tool for cri-du-chat in the shape of a YAC clone that may span the entire critical region. 24 refs., 4 figs., 2 tabs.

    2014-05-01

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

  1. Obstacles to communication in children with cri du chat syndrome.

    Science.gov (United States)

    Virbalas, Jordan M; Palma, Gina; Tan, Melin

    2012-11-01

    Cri du chat syndrome (CCS) is a genetic disorder resulting from the deletion of the short arm of chromosome 5. Perhaps the most distinctive characteristic of this syndrome is the congenital high-pitched cry, which frequently brings these patients to the attention of an otolaryngologist. Speech and language development in children with CCS is notable for a reduced receptive vocabulary and a profound deficit in expressive language. Currently, no clear guidelines have been established for the treatment of the speech and language difficulties exhibited by these patients. In this article, we present a case report and discuss the current literature regarding the challenges to effective communication in CCS. Case report. We present a 7-year-old girl with CCS who sought help to improve her ability to communicate. The patient presented with a persistent high-pitched voice unchanged since birth and a breathy dysphonia. Findings on examination were significant for an abnormally oriented larynx with atrophic vocal folds. She continues to undertake intensive speech therapy to assist in her language development. CCS is a genetic disorder that universally results in profound deficits in expressive speech. Although patients with CCS commonly present with a high-pitched voice and marked laryngeal abnormalities, they are unlikely to benefit from surgical intervention. Speech and language therapy, including augmentative communication devices, may enhance effective communication and improve the quality of life of these patients.

    It has been well established that the 5p deletion causes Cri du chat syndrome, typically characterized by a cat‑like cry, and that duplication of 18q causes Edwards syndrome; the two are rare genetic abnormalities that separately lead to physical and mental impairments. However, the severity of the clinicopathological characteristics that arise when these two aberrations occur in one patient is unknown. Here, the first case in our knowledge of a single patient (a two‑year‑old female) with 5p partial monosomy and 18q partial trisomy is described. In the present study, chromosome microarray analysis was performed, which identified the imbalance of chromosomes 5 and 18 in the patient. The chromosome aberrations were further confirmed by fluorescence in situ hybridization. By comparing the phenotypes of combined case with those of the individual syndromes, severe clinical phenotypes of the 5p (5p15.33‑p13.3) deletion were confirmed, however, the net effect of the duplication of 18q22.3‑q23 was not determined, as this duplication only appeared to have a weak effect on the patient's phenotypes. The correlation between these chromosomal aberrations and their clinical features has implications for the identification of critical regions of 5p and 18q, particularly for the functional mapping of chromosome 18.

    Communication is the sole means by which effective networking and co-existence is accomplished amongst living beings. Microbes have their own chit-chats. Science has overheard these microbial gossips and have concluded that these aren't just informal communications, but carefully coordinated signals that plan their effective strategies. Tracking one such signal molecule, N-acyl homoserine lactone (AHL), led to a fundamental understanding to microbial quorum sensing (QS). Furtherance of research sought for ways to cut off communication between these virulent forms, so as to hinder their combinatorial attacks through quorum sensing inhibitors (QSIs). A clear understanding of the inhibitors of these microbial communication systems is vital to destroy their networking and co-working. The current review, consolidates the solutions for QSIs offered from natural sources against these micro components, that are capable of slaughtering even nature's most fit entity-man. The applications of effective out sourcing of this QSI technologies and the need for development are discussed. The importance of silencing this microbial chatter to various aspects of human life and their implications are discussed and elaborated. Copyright © 2017 Elsevier B.V. All rights reserved.

    Our Multi-INT Data Association Tool (MIDAT) learns patterns of life (POL) of a geographical area from video analyst observations called out in textual reporting. Typical approaches to learning POLs from video make use of computer vision algorithms to extract locations in space and time of various activities. Such approaches are subject to the detection and tracking performance of the video processing algorithms. Numerous examples of human analysts monitoring live video streams annotating or "calling out" relevant entities and activities exist, such as security analysis, crime-scene forensics, news reports, and sports commentary. This user description typically corresponds with textual capture, such as chat. Although the purpose of these text products is primarily to describe events as they happen, organizations typically archive the reports for extended periods. This archive provides a basis to build POLs. Such POLs are useful for diagnosis to assess activities in an area based on historical context, and for consumers of products, who gain an understanding of historical patterns. MIDAT combines natural language processing, multi-hypothesis tracking, and Multi-INT Activity Pattern Learning and Exploitation (MAPLE) technologies in an end-to-end lab prototype that processes textual products produced by video analysts, infers POLs, and highlights anomalies relative to those POLs with links to "tracks" of related activities performed by the same entity. MIDAT technologies perform well, achieving, for example, a 90% F1-value on extracting activities from the textual reports.

  5. Immunohistochemical localization of choline acetyltransferase during development and in Chats mutants of Drosophila melanogaster.

    Gorczyca, M G; Hall, J C

    1987-05-01

    The distribution of choline acetyltransferase (CAT) in the nervous system of Drosophila melanogaster was determined by indirect immunohistochemical procedures using a monoclonal antibody specific to the enzyme. Immunoreactivity was first detected in the nervous system of 16 hr embryos, and increased considerably by the end of embryogenesis. Neuropil was preferentially stained, though cell bodies could also be observed. Staining was prominent in the CNS of all 3 larval instars but decreased substantially during the mid-pupal stage. Prior to eclosion, the level of immunoreactivity increased and the adult staining pattern became discernible. In the adult brain, staining was extensive, with numerous structures, such as the optic lobes and mushroom bodies, staining strongly. The adult thoracic ganglia were also moderately immunoreactive. These results imply a wide distribution of cholinergic neurons in the CNS of Drosophila. Immunoreactivity was also determined for 2 temperature-sensitive CAT mutants, Chats1 and Chats2. These files exhibit reduced CAT activity at permissive temperature, 18 degrees C, which eventually falls to undetectable levels after incubation at nonpermissive temperature, 30 degrees C. Chats2 mutants, after incubation at either 18 or 30 degrees C displayed virtually no staining. This result indicated that the immunoreactivity observed in wild-type flies was specifically associated with the enzyme encoded by the Cha gene. The intensity of staining in Chats1 mutants incubated at 18 degrees C appeared greater than in control flies, even though CAT enzyme activity in Chats1 is lower. This suggests that the enzyme molecule itself is structurally altered in Chats1 mutants. After incubation at 30 degrees C, staining in Chats1 flies decreased but did not disappear.

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

  7. Impaired spatial working memory and altered choline acetyltransferase (CHAT) immunoreactivity and nicotinic receptor binding in rats exposed to intermittent hypoxia during sleep.

    2007-02-27

    Exposure to intermittent hypoxia (IH), such as occurs in sleep-disordered breathing (SDB), is associated with cognitive impairment, neurodegeneration, oxidative stress, and inflammatory responses within rodent brain regions such as the basal forebrain. In this region, damage to cholinergic neurons correlates with working memory deficits in a number of neurodegenerative disorders, suggesting that degeneration of cholinergic systems may also contribute to the working memory impairments observed after IH exposures. We therefore examined basal forebrain choline acetyltransferase (CHAT) immunohistochemistry, nicotinic receptor binding in the prefrontal cortex (PFC), and working memory, in male rats tested on a delayed matching to place (DMP) task in the water maze following exposure to either room air (RA) or intermittent hypoxia (IH; alternating 90s epochs of 21% and 10% O(2) during sleep). IH-treated animals displayed impaired working memory with respect to controls, along with significant reductions in CHAT-stained neurons in the medial septal nucleus, in both the vertical and horizontal limbs of the diagonal band, and the substantia inominata after 14 days of IH exposure. In addition, increases in nicotinic binding and receptor affinity in the PFC were observed after 14 days of IH exposure. Thus, a loss of cholinergic neuronal phenotype in the basal forebrain may contribute to the cognitive impairments associated with CIH exposure. However, compensatory mechanisms may also be activated in other brain regions, and may provide potential therapeutic targets for the cognitive impairments associated with SDB.

  8. Characterization of CHAT and Cox type 1 live-attenuated poliovirus vaccine strains.

    Martín, Javier; Minor, Philip D

    2002-06-01

    CHAT and Cox type 1 live-attenuated poliovirus strains were developed in the 1950s to be used as vaccines for humans. This paper describes their characterization with respect to virulence, sensitivity for growth at high temperatures, and complete nucleotide and amino acid sequences. The results are compared to those for their common parental wild virus, the Mahoney strain, and to those for two other poliovirus strains derived from Mahoney, the Sabin 1 vaccine strain and the mouse-adapted LS-a virus. Analysis of four isolates from cases of vaccine-associated paralytic poliomyelitis related to the CHAT vaccine revealed genetic and phenotypic properties of the CHAT strain following replication in the human gut. CHAT-VAPP strain 134 contained a genome highly evolved from that of CHAT (1.1% nucleotide differences), suggesting long-term circulation of a vaccine-derived strain in the human population. The molecular mechanisms of attenuation and evolution of poliovirus in humans are discussed in the context of the global polio eradication initiative.

  12. Cyberspace as a new arena for terroristic propaganda: an updated examination.

    Science.gov (United States)

    Minei, Elizabeth; Matusitz, Jonathan

    2012-11-01

    This paper analyzes the role of propaganda use in cyberterrorism. The main premise is that cyberterrorists display various semiotic gestures (e.g., the use of images and Internet videos) to communicate their intents to the public at large. In doing so, they communicate themes-these themes range from hate to anger. Cyberterrorism, then, is a form of theater or spectacle in which terrorists exploit cyberspace to trigger feelings of panic and overreaction in the target population. In many cases, this form of propaganda is the primary means of communication for various cyberterrorist groups to convey their intents. Internet sites also produce numerous opportunities for in-group communication and publicity.

    The cri du chat syndrome or 5p deletion syndrome is a well-delineated clinical entity and has an incidence of 1/50,000 in newborn infants. A de novo deletion is present in 85% of the patients. Ten to 15% are familial cases with more than 90% due to a parental translocation and 5% due to an inversion of chromosome 5. Although the size of the deleted segment varies, the critical segment that is deleted in all patients appears to be 5p15.2. The clinical picture is well known in younger patients and includes the typical high-pitched cry, psychomotor retardation, microcephaly, growth rate failure, and craniofacial abnormalities including round face, hypertelorism, broad nasal bridge, downward slanting palpebral fissures, and micrognathia. With advancing age, the clinical picture becomes less striking. We present seven patients with 5p deletion syndrome, who were between age 16 and 47 years. Comparing their phenotype at several ages, a change of their phenotype was noted. Some of the clinical characteristics became more evident such as long face, macrostomia, and scoliosis. All patients were severely or profoundly mentally retarded except one patient who was mildly mentally retarded. The diagnosis was difficult to make in some of the patients who were first seen at an older age. In some of them, the craniofacial appearance resembled that seen in Angelman syndrome. Most patients had periods of destructive behavior, self mutilation, and aggression. The clinical diagnosis should be confirmed as soon as possible with cytogenetic investigation to provide specific support, prevention, and treatment of complications. Therefore, it is important to perform follow-up studies in young children to determine their outcome after infant-stimulation programs.

    Full Text Available O presente trabalho trata do uso do ciberespaço no ensino da literatura, seja em nível escolar médio ou universitário. Para tanto, apresentamos o relato de duas experiências realizadas com blogs em três turmas do curso de Letras da Universidade Estadual de Maringá nas disciplinas de “Literatura Brasileira: Poesia” e “Tópicos Especiais de Literatura Brasileira”. Após o relato destas experiências, apontado os critérios de avaliação, a metodologia e os resultados, passamos a considerar o uso de chats na realização de oficinas on-line de criação literária. Os resultados da experiência pedagógica realizada com os blogs apresentam-se bastante satisfatórios, pois – de modo geral – seu uso revelou-se uma estratégia muito positiva para fazer com que os alunos produzam mais e diversos tipos de textos, interajam mais com os conteúdos, os colegas e o professor, deixando de serem passivos na relação professor-aluno, e passem a vivenciar o conhecimento como algo dinâmico, percebendo sua produção como processo. Para encerrar, apresentamos dicas de sites e revistas literárias e culturais on-line que podem ser utilizadas pelos alunos e professores de literatura

    2011-10-01

    This documental case study was performed using a qualitative approach, and analyzed the dialogues of Nursing students in a context mediated by an educational chat in a Virtual Learning Environment (VLE). The data consisted of eight discussions among students, professors and monitors of the Rio Grande do Sul Federal University College of Nursing on the TelEduc® VLE chat on the activity called Virtual Client. The data were categorized using NVivo® software; and the information was analyzed using the Content Analysis technique. The results revealed feelings such as anxiety, fear and motivation towards hospital practice, as well as the dichotomous position of students regarding the proposed activity: some enjoyed the virtual discussions, while others preferred having discussions in person. This article presents recommendations for using educational chats in Nursing education.

    Full Text Available This article is an important part of the doctoral thesis topics “Configuration of the semiotics of the chat: a multimodal view”, in which the reflection on the media and the means of production ownership is proposed, from the relationship between the users of electronic devices and the virtual – real ownership consequences, bearing in mind that the cloud production relation and the electronic interaction bring about a series of epistemological implications characterized by the virtuality whose market and process of interaction is the web. This interaction allows a straight relationship with the research about the chat in a cyberculture world and specifically the chat as an emergent language, since the relationship between the language and the culture, the language and the knowledge and the most relevant one, the language and the economy, from a production system point of view, are a way to understand the symbolic products of the current society

    2016-06-01

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

    2013-05-01

    This study aims to examine the feasibility and acceptability of an Internet-based chat support group for parents implementing family-based treatment (FBT). Participants (N = 13) were parents of adolescents with eating disorder who participated in 15 weekly online therapist-guided chat sessions. Sessions focused on encouraging and supporting parental efforts to help their child overcome an eating disorder. Chat programme satisfaction ratings were high (91.7%). Participants reported looking forward to chat sessions and would recommend the chat to others. The vast majority reported that the chat helped them cope with their child's eating disorder and to implement FBT. Participants reported feeling that they could talk openly and honestly in sessions and had a sense of belonging to the group. Relatively few technical problems were reported, and the chat was rated as accessible, convenient and easy to use. Findings provide preliminary support for the utility of an online parent chat as an adjunct to FBT. Copyright © 2012 John Wiley & Sons, Ltd and Eating Disorders Association.

    2014-01-01

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

    2017-01-01

    Background Little empirical evidence exists on the effectiveness of using Twitter as a two-way communication tool for public health practice, such as Twitter chats. Objective We analyzed whether Twitter chats facilitate engagement in two-way communications between public health entities and their audience. We also describe how to measure two-way communications, incoming and outgoing mentions, between users in a protocol using free and publicly available tools (Symplur, OpenRefine, and Gephi). Methods We used a mixed-methods approach, social network analysis, and content analysis. The study population comprised individuals and organizations participating or who were mentioned in the first #LiveFitNOLA chat, during a 75-min period on March 5, 2015, from 12:00 PM to 1:15 PM Central Time. We assessed audience engagement in two-way communications with two metrics: engagement ratio and return on engagement (ROE). Results The #LiveFitNOLA chat had 744 tweets and 66 participants with an average of 11 tweets per participant. The resulting network had 134 network members and 474 engagements. The engagement ratios and ROEs for the #LiveFitNOLA organizers were 1:1, 40% (13/32) (@TulanePRC) and 2:1, −40% (−25/63) (@FitNOLA). Content analysis showed information sharing (63.9%, 314/491) and health information (27.9%, 137/491) as the most salient theme and sub-theme, respectively. Conclusions Our findings suggest Twitter chats facilitate audience engagement in two-way communications between public health entities and their audience. The #LiveFitNOLA organizers’ engagement ratios and ROEs indicated a moderate level of engagement with their audience. The practical significance of the engagement ratio and ROE depends on the audience, context, scope, scale, and goal of a Twitter chat or other organized hashtag-based communications on Twitter.

  1. Mass Surveillance and the Militarization of Cyberspace in Post-Coup Thailand

    Directory of Open Access Journals (Sweden)

    Pinkaew Laungaramsri

    2016-12-01

    Full Text Available Post-coup Thailand has witnessed a troubling shift toward censorship, surveillance, and suppression in cyberspace. With cyber security ranking prominently on the military’s agenda and the expansion of the military’s cyber intervention, the country’s online infrastructure has undergone politicization, securitization, and militarization. This paper argues that the militarization of cyberspace in Thailand represents the process in which cyber warfare capabilities have been integrated with other military forces and with support from the masses. This process has been effective through at least three significant mechanisms, including mass surveillance, surveillance by the masses, and normalization of surveillance. Social media have been turned into an absolute digital panopticon. Cyber dystopia, created by the 2014 coup and supported by the masses, has served to sustain a ‘state of exception’ not only within the territorial borders of the state, but also more importantly, within the virtual space of civil society. Cyber surveillance by the military and the masses has continued to jeopardize the already vulnerable Thai democracy.

  2. The interface between cyberspace and psychotherapeutic space. Relationship avoidance and intimacy in adolescent psychotherapy.

    Israeli, Etziona; Asulin-Simhon, Zehorit; Sharabany, Ruth

    2013-01-01

    This paper documents one aspect of an adolescent boy's psychotherapy, as a basis for discussion of the theoretical issues for introducing cyberspace communication into psychodynamic therapy. The patient's "blogging" serves as a platform for consideration of several seemingly contradictory functions. It is an avenue for the patient to reveal himself while maintaining comfortable control and also avoiding direct contact with the therapist and diluting communication. The blog writing allows for the regulation of emotions to some degree as well as an experience of solitude with an imagined audience. This therapy is in the context of the adolescent roller coaster--loss, anger, distancing while yearning for intimacy, and acting out. Changes in the therapy are mirrored by vicissitudes in the function and content of the blog. Cyberspace communication is a hallmark of the present generation. The implications of introducing it into adolescent therapy as well as refraining from it need to be considered. We attempt here to examine the role of this new space with regard to the patient, the therapist, the therapeutic relationship, and the course of therapy.

En el ciberespacio se dan modalidades audiovisuales características: cibercine, cibertelevisión, televisión a la carta y cibervídeo. Los usos sociales del vídeo en el ciberespacio se solapan con los informativos en un proceso de comunicación horizontal, de enorme potencial, pero que presenta riesgos de fragmentación de la esfera pública. El vídeo es factor de globalización y vector del info-entretenimiento que coloniza tanto el espacio mediático como el ciberespacio. En el lenguaje hipermedia los elementos expresivos del lenguaje audiovisual clásico se fragmentan. Es necesario explorar nuevos modos interactivos de lenguaje audiovisual e investigar cómo el vídeo vincula el espacio mediático y el ciberespacio en un nuevo ecosistema audiovisual.

  4. Adolescents' Perceptions of Popularity-Motivated Behaviors, Characteristics, and Relationships in Cyberspace and Cyber Aggression: The Role of Gender.

    Wright, Michelle F

    2017-06-01

    Research is increasingly revealing that adolescents utilize electronic technologies to promote and/or maintain their social standing among their peer group. Little is known about whether adolescents' perceptions of popularity-motivated behaviors, characteristics, and relationships in cyberspace are associated with popularity-motivated cyber relational aggression. It is also unclear how gender might impact these associations, especially considering that adolescent girls and boys differ in regard to the type of behaviors, characteristics, and relationships they believe contribute to popularity. To this end, this study examined the potential moderating effect of gender on the association between adolescents' perceptions of popularity-motivated behaviors, characteristics, and relationships in cyberspace and their engagement in popularity-motivated cyber relational aggression over 1 year, from seventh to eighth grade. There were 217 eighth graders (51 percent female; M age = 12.13) from three middle schools in a large Midwestern city in the United States included in this research. They completed questionnaires on their popularity-motivated behaviors, characteristics, and relationships in cyberspace and their perpetration of popularity-motivated cyber relational aggression during the seventh grade. One year later, they completed the perpetration of popularity-motivated cyber relational aggression questionnaire. The results revealed that the association between popularity-motivated behaviors, characteristics, and relationships in cyberspace and the perpetration of popularity-motivated cyber relational aggression was stronger for girls, while such an association was not found for boys. These findings indicate the importance of considering cyberspace as an environment in which adolescents can enhance their social standing among peers from their school.

    Cri Du Chat syndrome is a chromosomal disorder with peculiar clinical characteristics including airways abnormalities that require special care by anesthesiologists when handling those patients. To present a case of outpatient anesthesia in a patient with Cri Du Chat syndrome and discuss the anesthetic aspects related to this disorder. Male patient, 14 years old, 25 kg, with Cri Du Chat syndrome, physical status ASA P2, was admitted for upper gastrointestinal endoscopy and esophageal dilation. The patient had mental retardation, a few episodes of seizures, and marked hypertonia of the limbs. Airways exam showed limited cervical mobility and thyromental distance less than six centimeters. The patient was unable to comprehend verbal commands, making it difficult to undertake a complete assessment of the airways. Other findings on physical exam included microcephaly, micrognathism, subtle strabismus, limb hypertonia with flexion, and protrusion of the tip of the tongue. Intravenous fentanyl 50 μg, midazolam 1 mg, and propofol 60 mg were administered. The patient was maintained on spontaneous ventilation. The procedure lasted 5 minutes, without intercurrences. Patients with Cri Du Chat syndrome have clinical characteristics that are very important for their anesthetic management, being the responsibility of the anesthesiologist to consider carefully the structural particularities of each patient. © 2010 Elsevier Editora Ltda.

    West, Delia Smith; Harvey, Jean R.; Krukowski, Rebecca A.; Prewitt, T. Elaine; Priest, Jeffrey; Ashikaga, Takamaru

    2016-01-01

    Objective To examine whether the addition of online MI chats to a web-based, group behavioral obesity treatment program augments weight loss outcomes relative to the web-based online weight control program alone. Methods Healthy individuals (N=398, 24% minority) with overweight/obesity were randomized to a 36-session group internet behavioral weight control treatment (BT) or the same group internet treatment plus 6 individual MI chat sessions (BT+MI). Both conditions received weekly synchronous online chat group sessions for 6 months followed by 12 monthly group chats. Participants in both groups received identical behavioral lessons and individualized therapist feedback on progress toward meeting exercise and calorie goals. BT+MI also received 6 individual MI sessions delivered by a separate MI counselor via web chat. Weight loss was measured at 6- and 18-months. Results There were no significant differences in weight loss between BT (−5.5±6.0 kg) and BT+MI (−5.1±6.3 kg) at 6-months or at 18-months (−3.3±7.1 kg vs −3.5±7.7 for BT and BT+MI, respectively). Attendance at group chats did not differ between groups, nor did self–monitoring patterns, suggesting comparable engagement in the weight control program in both conditions. Conclusions Online MI chat sessions are not a viable strategy to enhance web-based weight control treatment outcomes. PMID:27616628

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

    2016-10-01

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

    Previous studies showed that social media is associated with sleep quality. WeChat (a native social media in China) is very popular in China, especially among the youth. In the second quarter of 2016, Tencent's WeChat had 806 million monthly active users. The study sought to identify the influence of WeChat on the sleep quality among undergraduate students. A cross-sectional survey adopted a multi-stage stratified sampling survey to investigate undergraduates in Chongqing, China. Data were collected on 1979 eligible adults, aged 20.27 (SD: 1.26) years old, using Pittsburgh Sleep Quality Index (PSQI) to measure sleep quality. Respondents aged 20.27 ± 1.26 years included 535 (27.0%) males, and 1311 (66.3%) reported as having poor sleep quality. Of the 1979 participants, 1320 (66.70%) were WeChat users. In multivariable analyses, gender, grade, nationality, living costs, the student leader, the only child, type of university, WeChat usage was associated with domains of PSQI among undergraduates ( p  WeChat users had a lower score of subjective quality of sleep, sleep latency, use of sleeping medication, daytime dysfunction, and global PSQI score ( p  WeChat users may have better sleep quality than non-WeChat users among undergraduates. To determine causal relationships, further longitudinal studies will be required to test for the association between WeChat users and sleep quality. This study may also provide some implications for health promotion on sleep quality of undergraduate students.

    2009-01-01

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

    Cri du Chat syndrome (CdCS) is a genetic syndrome caused by deletions in the short arm of chromosome 5. Although the main clinical features of CdCS are well known, the neurocognitive and behavioural characteristics of the phenotype are rarely described in detail in the literature. In this study, we analysed the main phenotypic features of CdCS from a parental perspective. A questionnaire was sent to 700 Brazilian families that were registered in the Brazilian Association of CdCS. The questions involved specific domains of CdCS, such as pregnancy and birth conditions, recurrence of the disease in the family, current major health problems, and aspects of cognitive development. In total, 73 questionnaires were completed: 44 females and 29 males, ranging from 9.5 months old to 40 years old (mean = 13.8 years; median = 12 years). Most of the parents noticed the typical cat-like cry at birth (94.4%). The age at diagnosis of CdCS ranged from the time of birth to 180 months (mean = 14 months; median = 6 months), while one case was diagnosed during pregnancy. In all of the cases, the diagnosis of CdCS was made by G-banding karyotype analysis. In 66.2% of the cases, the parents underwent cytogenetic investigation. A total of 52.1% of the parents answered that they did not remember what the recurrence risk of CdCS was in their family. The main health problems that were reported were as follows: swallowing problems (80.3%), feeding problems (80.3%), congenital heart disease (31.5%), spine abnormalities (28.8%), and neurological symptoms (20.5%), including seizures (11%). The behavioural problems that were reported were as follows: aggressive behaviour, stereotypies, anxiety, phobias, and genital manipulation/masturbation. Neurodevelopmental delay was reported in all of the cases. Independent walking was achieved in 72.2% of the patients. Approximately 50% of the patients never presented expressive language, and most of the patients are dependent on others for

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

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

    Full Text Available This paper attempts to give an overview of the different representations of the pilgrimage to Mecca found in the ‘liminal space’ of the internet. For that purpose, it examines a handful of emblematic examples of how the hajj is being presented and discussed in cyberspace. Thereby, special attention shall be paid to the question of how far issues of religious authority are manifest on these websites, whether the content providers of web pages appoint themselves as authorities by scrutinizing established views of the fifth pillar of Islam, or if they upload already printed texts onto their sites in order to reiterate normative notions of the pilgrimage to Mecca, or of they make use of search engine optimisation techniques, thus heightening the very visibility of their online presence and increasing the possibility of becoming authoritative in shaping internet surfers’ perceptions of the hajj.

    The task of topic detection becomes the hotspot research direction in the field of natural language processing in recent years. The cyberspace public opinion has given the significant impact on the large numbers of internet users. This makes the effective public opinion detection and tracking become very important. We select the effective features in the story document and the vector center model is taken to represent the text document. The algorithm of distance based clustering is carried out for public opinion detection. It identifies the emergence of new events and also merges the story to the corresponding cluster. Finally, we give the performance evaluation by the F-Value and entropy value. The system achieves the performance of 76% F value on the test set. The technique of topics detection can monitor the information sources in various languages, and it will provide the efficient guidance for judging the hot spots on the web.

  15. The Intersecting Worlds of Sustainability and Cyberspace: Old or/and New Boundaries

    2013-11-01

    The world is replete with boundaries at all scales, personal, community, disciplinary, national and global. Some of these are open and permeable; others are closed and difficult to cross. The fields, concepts and models associated with studying global sustainability call for an examination of both old boundaries and new boundaries, especially those that intersect different disciplines, scales and technologies. In this presentation I want to focus on new transdisciplinary boundaries that are essential for us to study sustainability at local and global levels and also cyberspace worlds where there is much fluidity, speed, networking that relate to issues of identity and territoriality. I discuss both what is similar to "old" or "traditional boundary thinking" and what is "new." I conclude by suggesting some challenges facing transitional boundary research and policy.

    My journey through Cyberspace began about 20 years ago with an introduction to e-mail. A few years later, I had the good fortune of working with artificial intelligence engineers who were developing information retrieval techniques and expert systems. By serendipity this led to an early introduction to the World Wide Web (www) and the use of Web browsers as tools for gathering information, long before the Internet became commercialized. Internet content and form are now so omnipresent that they have affected our language in both amusing and utilitarian ways. We are entering an era where social networking, from personal to professional lives, is potentially a vibrant new direction for the Internet. Future articles for this feature will explore how to maximize the utility of the Internet.

    Information security continues to evolve in response to disruptive changes with a persistent focus on information-centric controls and a healthy debate about balancing endpoint and network protection, with a goal of improved enterprise/business risk management. Economic uncertainty, intensively collaborative styles of work, virtualization, increased outsourcing and ongoing compliance pressures require careful consideration and adaptation. The Cyberspace Security Econometrics System (CSES) provides a measure (i.e., a quantitative indication) of reliability, performance, and/or safety of a system that accounts for the criticality of each requirement as a function of one or more stakeholders interests in that requirement. For a given stakeholder, CSES accounts for the variance that may exist among the stakes one attaches to meeting each requirement.

  18. IPY Data Management - How one can deploy a virtual observatory in cyberspace?

    Papitashvili, V. O.

    2006-12-01

    Proliferation of global observing systems and distributed scientific and operational databases challenges human abilities to comprehend effectively ever increasing volume of information about the Earth and geospace. At the same time, better communication and advent of the Internet and World Wide Web provide effective means for development of sophisticated search engines capable of identifying discipline-specific data on the Web and then retrieving requested intervals for scientific analyses or practical applications. By analogy with physical observatories deployed over the Globe and in Geospace, a concept of "Virtual Observatory" has been introduced where a personal computer can serve as an "observing" instrument that retrieves specific data from remote Internet servers and data provider nodes. Thus, collecting astronomical data from many telescopes located elsewhere in the World (and even in space) via the Internet, one can turn his/her computer to a great telescope equivalent to Hubble or Mauna Kea world-class instruments. Similar approach can turn personal computers into global magnetic, atmospheric, oceanographic, ecological (you name it!) observatories if the data from corresponding disciplines are available from the World Wide Web. Thus, we postulate here that a "Virtual Observatory" can only be deployed in cyberspace if a discipline-specific data structure (primitive or sophisticated) becomes available electronically - that is, if the appropriate "data fabric" is created in cyberspace, making itself available for search and retrieval by any software (or middleware) packages developed and installed at a single (i.e., portal-based) Internet server or at a number of personal computers (nodes) with open FTP or HTTP (or SSL and S-HTTP) ports through which specific scientific data are provided. (Generally speaking, these data may not be necessarily "scientific"; the proposed concept is applicable for "Virtual Corporation" or "Virtual Retailer" networks as well

    Chlamydia notifications have been rising in Australia for over a decade and are highest in young people. This study aimed to evaluate the impact of an internet-based intervention on chlamydia testing among young people 16-25 years. In this randomised controlled trial, recruitment, data collection, study interventions and follow-up occurred entirely in cyberspace, facilitated by a website. Eligible participants were aged 16-25 years and resided in Australia. The intervention group received personalised emails inviting interaction about chlamydia testing, while the control group received regular impersonal emails. Primary outcome was self-reported chlamydia testing at 6-month follow-up; secondary outcomes were condom use and changes in knowledge and attitudes. 704 young people completed baseline information, 40 were excluded and five withdrew prior to follow-up. The follow-up rate was 47.3% overall. In the intervention group, 40.6% (95% CI 30.7% to 51.1%) reported having had a chlamydia test at follow-up compared with 31.0% (95% CI 24.8% to 37.2%) in the control group (p=0.07). A per-protocol analysis found that those who engaged in email interaction were more likely to report chlamydia test uptake compared with those in the control group (52.5%, 95% CI 39.3 to 65.4% cf 31.0%, 95% CI 24.8% to 37.2%, p=0.002). There were no differences in secondary outcomes between groups. This is the first randomised controlled trial undertaken in cyberspace to promote chlamydia testing. E-technology may be useful in promoting chlamydia testing and healthcare seeking behaviour in young people.

    Little empirical evidence exists on the effectiveness of using Twitter as a two-way communication tool for public health practice, such as Twitter chats. We analyzed whether Twitter chats facilitate engagement in two-way communications between public health entities and their audience. We also describe how to measure two-way communications, incoming and outgoing mentions, between users in a protocol using free and publicly available tools (Symplur, OpenRefine, and Gephi). We used a mixed-methods approach, social network analysis, and content analysis. The study population comprised individuals and organizations participating or who were mentioned in the first #LiveFitNOLA chat, during a 75-min period on March 5, 2015, from 12:00 PM to 1:15 PM Central Time. We assessed audience engagement in two-way communications with two metrics: engagement ratio and return on engagement (ROE). The #LiveFitNOLA chat had 744 tweets and 66 participants with an average of 11 tweets per participant. The resulting network had 134 network members and 474 engagements. The engagement ratios and ROEs for the #LiveFitNOLA organizers were 1:1, 40% (13/32) (@TulanePRC) and 2:1, -40% (-25/63) (@FitNOLA). Content analysis showed information sharing (63.9%, 314/491) and health information (27.9%, 137/491) as the most salient theme and sub-theme, respectively. Our findings suggest Twitter chats facilitate audience engagement in two-way communications between public health entities and their audience. The #LiveFitNOLA organizers' engagement ratios and ROEs indicated a moderate level of engagement with their audience. The practical significance of the engagement ratio and ROE depends on the audience, context, scope, scale, and goal of a Twitter chat or other organized hashtag-based communications on Twitter. ©Kristina M Rabarison, Merriah A Croston, Naomi K Englar, Connie L Bish, Shelbi M Flynn, Carolyn C Johnson.

    The Wellness Engagement (WE) Project is an academic-community partnership developed to engage the community to inform the development of a pilot intervention aimed at promoting healthy eating and physical activity among residents of Petersburg, Virginia. To implement House Chats as a novel methodology for engaging community members in focused discussion about obesity, exercise, dietary intake, and barriers to health. We recruited and trained laypersons as House Chat Leaders (HCLs) to host informal group discussions about obesity with members of their network in a social setting following predetermined questions. HCLs hosted 34 House Chats with 176 participants over a period of 4 months. The House Chat proved to be a highly successful engagement strategy that allowed access to respondents who may not have participated in a traditional, focus group discussion.

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

    Zbigniew ŁĘSKI

    2017-11-01

    Full Text Available Over the last few years cyberspace has become a significant element of the surrounding social reality. For many people who currently perform the role of parents new contemporary media, which enabled cyberspace development, are something that occurred in their lives only during their adulthood or while entering adulthood. Thus, their use of the media does not always belong to activities that proceed intuitively and naturally. This problem looks completely different from the perspective of a child who was born surrounded by the media, is being brought up constantly dealing with them and remaining under their significant influence. Thus, it is often the child, who is better able to move in cyberspace than his parents and who becomes their guide in the digital world. In this context, it seems to be important to analyse the phenomenon of entering into a specific relationship with the media and equating them with reality. This phenomenon has been observed and demonstrated in a series of experiments by B. Reeves and C. Nass2 . Thus, in the current layout of family relationships we can observe a significant new element – the new media. To what extent is this new relationship important? How much does it affect the quality of family functioning? These questions have not been answered, yet. It appears that, so far, no method that would allow carrying out research examining the problems signalled above has been created. The author of the present study suggests applying the theory of the transactional analysis and using the terminology and research tools provided by it. This theory may enable the analysis of family relationships, taking into account the presence of the new media and cyberspace in the environment that is being studied.

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

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

    2017-03-01

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

    2016-02-01

    Full Text Available 'This paper provides an overview of the evolution of the concept of jihadism as it presently exists in cyberspace. From its roots during the Chechen conflict to the current use of social media by the Islamic State (IS, this paper identifies and examines three highly significant paradigm shifts: (1 the emergence of rudimentary Web 2.0 platforms and jihadist forums; (2 the advent of advanced Web 2.0 and social media platforms as methods of spreading jihadism; and (3 turn towards ‘lone wolf’ terrorism.  In this paper, the author argues that IS’ extensive reliance on unaffiliated sympathizers, who either re-tweet or re-post content produced and authorized by the IS leadership can be seen as a groundbreaking paradigm shift in the evolution of jihadism in cyberspace. Furthermore, it is also argued that IS’ strategy of empowering of unaffiliated sympathizers represents a further development in the evolution of jihadism in cyberspace and can best be understood as an attempt to normalize and legitimize IS’ existence through its efforts to dominate the ‘IS narrative’ across social media platforms.'

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

    2015-10-01

    Full Text Available Introduction Cri du chat syndrome is a rare genetic disorder due to deletion of variable length of short arm of chromosome 5(5p. It mainly presents with typical cat like cry, facial dysmorphism, poor growth with feeding problems and severe cognitive, speech, and motor delays. Case Report We present here a one year old child who did not presented with typical features but presented with recurrent pneumonia with chronic stridor since early infancy. On evaluation we found short flabby epiglottis and we did karyotyping which showed 5P deletion syndrome. Conclusion Cri du chat syndrome can be presented with atypical features like chronic stridor and recurrent pneumonia without having typical cat like cry. Early diagnosis is necessary for proper counselling of parents and treatment of the patient.

    Le syndrome du Cri du Chat (Cri du Chat syndrome, CdCS) est une anomalie chromosomique résultant d’une délétion de taille variable de l’extrémité du bras court du chromosome 5 (5p), incluant une région critique située en p15.2. Il représente une des délétions chromosomiques les plus fréquentes, son incidence dans la population générale est de 1/20 000 à 1/50 000. Les caractéristiques cliniques comprennent un cri monochromatique aigu, une microcéphalie, une dysmorphie cranio-faciale caractéristique évoluant avec l’âge et un retard mental et psychomoteur important. La taille de la délétion est variable, Le traitement est fonction des différents symptômes. Un remaniement chromosomique parental est retrouvé dans 12% des cas et la majorité des délétions responsables de la maladie du cri-du-chat surviennent de novo. Nous présentons une observation d’un syndrome du Cri du Chat, confirmé par caryotype métaphasique (46,XY,del(5)(p13) de novo). A travers cette observation nous mettrons à jour, les actualités scientifiques de ce rare syndrome, ainsi que la place des explorations cytogénétiques dans le diagnostic précis et le conseil génétique des syndromes dysmorphiques.

    Cri du chat syndrome (CdCS) and primary ciliary dyskinesia (PCD) are rare diseases that present with frequent respiratory symptoms. PCD can be caused by hemizygous DNAH5 mutation in combination with a 5p segmental deletion attributable to CdCS on the opposite chromosome. Chronic oto-sino-pulmonary symptoms or organ laterality defects in CdCS should prompt an evaluation for PCD. Copyright © 2014 Elsevier Inc. All rights reserved.

    Evidence suggests that there is variation in support for specific chicken farming practices amongst stakeholder groups, and this should be explored in more detail to understand the nature of these differences and work towards convergence. Online focus groups were used to assess attitudes to animal welfare in meat chicken farming in this pilot study. Across six online chats, 25 participants (general public, n = 8; animal advocacy group, n = 11, meat chicken industry, n = 3; research or veterinary practice who had experience with poultry but no declared industry affiliation, n = 3) discussed meat chicken intensification and welfare. Of those, 21 participants completed pre- and post-chat surveys gauging perceptions and objective knowledge about meat chicken management. Main reasons for intensification support were perceptions of improved bird health, and perceptions that it is a cost-effective, sustainable farming system. Reasons for opposition included perceptions that a large number of birds kept are in close proximity and have limited ability to perform natural behaviours. Misunderstandings about current practices were clarified in chats which contained industry representation. Participants agreed on the need for enforceable standards and industry transparency. Industry-affiliated members rated welfare of meat chickens higher, and gave lower ratings for the importance of natural living, than other stakeholder groups (both p = 0.001). On average, while objective knowledge of intensification increased after chat participation (p = 0.03), general welfare ratings and support for intensification did not change over time, counter to assertions that lack of knowledge results in lack of support for some practices.

    2018-04-01

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

    Full Text Available As customers are becoming increasingly connected to the internet, this means that they are available for online interviews, thus opening up a space for investigating research methods, especially qualitative research, in an attempt to identify how to adapt data collecting instruments to the so-called “connected customer era”. In this context, the focus of this article is on the application viability analysis of the laddering technique used online and in real-time chat by asking the following question: “Why caipirinha?”. Conducting online in-depth interviews through the MSN Messenger and Skype (the most commonly used chat tools in Brazil, 23 attributes, 22 consequences and 13 values were identified, resulting in 133 ladders, 71 of which reached the value level. Along with friends/mates, Integration, Entertainment and Fun, in addition to Alcohol, Insouciance/ relaxation and Pleasure constitute the most frequent ladders. Concerning the application itself, the participants gave positive feedback, even though some of them did not feel satisfied because they became tired. Convenience, objectivity, disinhibition, easy scheduling and flexibility were identified. The viability of online in-depth interviewing via real-time chats was confirmed, raising the question of the possibility of it achieving other qualitative research techniques.

  11. A neuropsychological-genetic profile of atypical cri du chat syndrome: implications for prognosis

    Cornish, K; Cross, G; Green, A; Willatt, L; Bradshaw, J

    1999-01-01

    Cri du chat syndrome is associated with a deletion on the short arm of chromosome 5. The main diagnostic feature is a high pitched, cat-like cry which has recently been localised to 5p15.3 and is separate from the remaining clinical features of the syndrome, which have been localised to 5p15.2. The present study describes a family of four who have a deletion slightly distal (5p15.3) to the critical region. Detailed neuropsychological evaluations indicated a similar pattern of cognitive performance to that reported for subjects with typical CDCS but with only minimal intellectual impairment. In addition, in this family the 5p deletion is transmitted in an autosomal dominant fashion, contrasting with most cases of CDCS, which are either de novo or occur as an unbalanced product of a balanced translocation in a normal parent. This study confirms the importance of differentiating between 5p deletions that coincide with the typical cri du chat phenotype which includes severe to profound learning disability and deletions that only delete the distal critical region that coincides with a milder degree of cognitive impairment and a much improved prognosis.

College & Research Libraries, 76(7, 959-974. http://dx.doi.org/10.5860/crl.76.7.959 Abstract Objective – To determine whether the complexity of reference questions has changed over time; whether chat reference questions are more complex than those at the reference desk; and whether proactive chat increases the number and complexity of questions. Design – Literature review and library data analysis. Setting – Library of a doctoral degree granting university in the United States of America. Methods – The study was carried out in two parts. The first was a meta-analysis of published data with empirical findings about the complexity of questions received at library service points in relationship to staffing levels. The authors used seven studies published between 1977 and 2012 from their literature review to create a matrix to compare reference questions based on the staffing level required to answer the questions (e.g., by a nonprofessional, a generalist, or a librarian. They present these articles in chronological order to illustrate how questions have changed over time. They sorted questions by the service point at which they were asked, either through chat service or at a reference desk. In the second part of the study authors used the READ scale to categorize the complexity of questions asked at the reference desk and via proactive chat reference. They collected data for chat reference for six one-week periods over the course of eight months to provide a representative sample. They recorded reference desk questions for three of those same weeks. Both evaluators scored the data for a single week to norm their results, while the remaining data was coded independently. Main Results – The complexity of questions in the seven articles studied indicated change over time

    Advanced control rooms (ACRs) for future nuclear power plants (NPPs) are being designed utilizing computer-based technologies. The U.S. Nuclear Regulatory Commission reviews the human engineering aspects of such control rooms to ensure that they are designed to good human factors engineering principles and that operator performance and reliability are appropriately supported in order to protect public health and safety. This paper describes the rationale and general approach to the development of a human factors review environment, the types of advanced technologies being addressed, the human factors issues associated with advanced technology, and the current state-of-the-art of human factors guidelines for advanced human-system interfaces (HSIs). The proposed approach to ACR review would track the design and implementation process through the application of review guidelines reflecting four review modules: planning, design process analysis, human factors engineering review, and dynamic performance evaluation

    Teaching planetary science using a spherical projector to show the planets' surfaces is a very effective but usually very expensive idea. Whatsmore, it usually assumes the availability of a dedicated space and a trained user. "Planets in a room" is a prototypal low cost version of a small, spherical projector that teachers, museum, planetary scientists and other individuals can easily build and use on their own, to show and teach the planets The project of "Planets in a Room" was made by the italian non-profit association Speak Science with the collaboration of INAF-IAPS of Rome and the Roma Tre University (Dipartimento di Matematica e Fisica). This proposal was funded by the Europlanet Outreach Funding Scheme in 2016. "Planets in a room" will be presented during EPSC 2017 to give birth to the second phase of the project, when the outreach and research community will be involved and schools from all over Europe will be invited to participate with the aim of bringing planetary science to a larger audience.

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

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

    2002-01-01

    The growth of the Internet has revolutionized how society conducts business in many areas. Not to be left behind, the sexual predator and the obsessional harasser have found cyberspace to be a vehicle capable of meeting their needs: obtaining information, monitoring and contacting victims, developing fantasy, overcoming inhibitions, avoiding apprehension, and communicating with other offenders. Although clearly disparate offender categories, these two groups are included in this article because of the likelihood of their using the Internet in pursuit of their goals. Forensic psychiatrists should become familiar with computers and the Internet so that they can conduct relevant psychiatric evaluations of such individuals and can advise attorneys, victims, and law enforcement personnel competently, when retained in that capacity. This article discusses the Internet and its use by the sexual predator and the obsessional harasser, highlighting information of interest to the forensic psychiatrist, including the poorly understood field of digital evidence. Aspects of the Internet, such as on-line dating and cybersex also are covered, because they relate to sexual predation and stalking.

    2006-01-01

    By mediating dissociative experiences, the Internet can challenge the boundaries of people's sense of identity. To illustrate this hypothesis, a case of dissociative identity disorder (DID) is presented. A young unemployed woman created and frequently played several characters in an online game. For more than 2 years she spent up to 12 h a day in the Internet, assuming various personalities, which in return intruded upon her neglected real life. During the course of an inpatient psychotherapeutic treatment, the clinical diagnosis of DID was confirmed by psychometric testing. After 12 weeks of psychotherapy, the patient had managed to identify her fragmented identities as character traits and integrated them into her core personality. She rearranged her real everyday life, found a new job, and reduced her online activities. Even though the patient's psychopathology stems from a disposition in terms of a personality disorder with histrionic and narcissistic features, excessive internet role play obviously functioned as a trigger to develop DIS. Conclusively, cyberspace's anonymous interactivity may offer the possibility to explore one's identity while also putting at risk its coherence.

    2015-01-01

    The study of epidemiologic processes as a form of socially determined movement requires a renewed understanding of the social order, and thus, an updated understanding of the social relations that move society. Recently, the dominance of big corporations on cyberspace has become visible as a new historical process that conditions the social order and extends the technological subordination of daily life, therefore expanding community massive submission to standard conducts. The new digital technological revolution, about which some frightening prognoses are made for the next decades, could easily imply the advent of an era of radical subsumption of life processes. This will negatively affect not only our general way of living, thinking and planning, but also our deepest daily intimacy. This movement implies radical effects on health which we call cybernetic determination and subsumption. This novel process raises new questions on public health and prevention; but also requires a new reading of reality, a rethinking of human life and health, of its social determination, which implies the need for new new categories and analysis and renewed challenges for critical epidemiology.

    Full Text Available Along with the rapid development of computers, computer networks have also been developed. Computer crimes are carried out in a specific environment - cyberspace, whose important characteristic is transnational scope, which goes beyond the control of the territorial nation-states. There is no doubt that computer networks can be subject of various abuses. They appear in a triple role: as a target or object of the attack, as a means or a tool, or as a framework of the offense. This kind of crime rapidly changes forms and forms of manifestation, the border between the states and the other injured. The biggest problem in this area is the misuse of the Internet, as the main global computer network communication, which has fundamentally revolutionized many areas of human life and work. The subject of this paperwork is analyzing the most important modalities of Internet abuse, as well as the scope and importance of using the Internet in a modern society.

    Full Text Available Online dating current is a popular activity in cyberspace. More and more people make new friends and find their partners through online dating web sites. There is an interesting observation that some people are more popular than others in online dating web sites. The current study focuses on the personal profile characteristics that make one a popular dater. By two field surveys, this study discusses the relationship between online daters' personal profiles and their popularity. The first survey investigated 800 online daters' profiles from dating web sites. The statistical analysis results indicated thatphysical body types and looks, education level, occupation, personality, and interests were characteristics that influenced the popularity of online daters, while significant gender differences were found in the characteristics that related to popularity of online daters. The second survey searched 960 online daters with profiles of popular and unpopular characteristics. By observing the popularity of these online daters, it was found that those with "popular" characteristics also were the popular daters and those with "unpopular" characteristics were the unpopular daters. This may serve as evidence that the found personal profile characteristics were indeed factors influencing the popularity of the online daters.

    If campaigns do not accommodate this view, all but a hard core of regulars and fired-up partisans will drift away, leaving it for staffers and hired hands to do all the hard work of identifying voters, canvassing people by foot and by phone, and turning out the vote. [...] ironically, a campaign...... that is singleminded in its instrumental pursuit of victory can thus be less effective than one that is more accommodating- a campaign that makes room for volunteers by accepting that, unlike staffers, they come to politics with a different perspective and conception of what is and ought to be going on....

    While transcatheter aortic valve replacement is considered a viable alternative to traditional surgery for patients with critical aortic stenosis, it is still a cardiac surgical procedure with a steep learning curve. Space consideration is a key aspect of the procedure's success. A TAVR program requires the commitment from and investment of institutional resources, the outfitting of an appropriate procedure room, and meticulous training of a multidisciplinary TAVR team. Careful integration of the various imaging modalities, medical specialties, and equipment is necessary to ensure the safety and efficacy of the procedure and to treat complications that may arise.

    The Cri du Chat syndrome is a segmental aneusomy associated with deletions in the short arm of human chromosome 5. More specifically, the cytogenetic band 5p15.2 must be deleted in order to manifest the typical phenotypic signs. We have studied several cell lines from individuals who have chromosomal abnormalities within this cytogenetic band but who do not have typical Cri du Chat syndrome. In fact, several individual studied have no discernible features of this syndrome. Using fluorescent in situ hybridization (FISH) analysis and PCR analysis on somatic cell hybrids we have mapped the breakpoints relative to each other within this band. There is a great degree of phenotypic heterogeneity between several of the patients, even those which share common breakpoints. This heterogeneity makes it very difficult to narrow the region of interest to a very small (<1 Mb) region. In order to more thoroughly analyze this region, we have assembled a yeast artificial chromosome (YAC) contig of part of this region. This contig has been analyzed for STS content and covers approximately a 1.5-2.0 Mb region within 5p15.2. In addition, we have constructed a radiation hybrid map of the region. The YACs contained within the minimal contig have been used as hybridization probes to isolate corresponding cosmid clones within the region of interest. These cosmids, in turn, are being utilized to obtain potential exons using exon amplification. Several cosmids within this region have been isolated by STS content and potential exons have been isolated from them. These exons have been used as probes to isolate cDNA clones from the region. It is our hope that isolation of genes throughout the region of interest will allow a better understanding of the etiology of Cri du Chat.

  12. The chatting gathering as a methodological strategy in in-service learning: moving along dialogical dynamics

    Full Text Available This article focuses on an experience of in-service training carried out by a group of educators in literacy. The novelty of the undertaking lies in the methodological proposal analysed: using “chatting gatherings” as a methodological strategy, which supports critical reflection and the construction of knowledge, both in in-service training of professionals and in basic adult education. This experience reveals the nature of learning achieved through dialogical educational processes. Further, it allows us to observe the impact that they may have on the improvement of the professionals’ educational practices.

  13. Unusual nocturnal feeding by Brown Rock-chat Cercomela fusca (Passeriformes: Muscicapidae in Bikaner, Rajasthan, India

    Full Text Available Brown Rock-chat is a diurnal insectivorous bird commonly associated with human habitations. I report here nocturnal foraging of the species in and around Bikaner in Rajasthan. The birds showed a marked bimodal activity during their nocturnal foraging which peaked in early morning and late evening hours. Bright sodium-vapour lights that attracted a horde of insects during monsoons offered ideal foraging opportunities for the birds. This behavior is explained here as an adaptation to maximize their food intake during the period when the birds breed and their nutritional requirements are naturally high.

    2012-07-01

    Full Text Available Le chat sur Internet est un moyen moderne de communication électronique ayant engendré de nouvelles pratiques d’écriture chez les usagers. Cet outil de communication emblématique est généralement connu pour les procédés graphiques de réduction, le caractère phonétique de l’écriture, ou encore les procédés d’expressivité. Ceci étant, si ces procédés graphiques sont les caractéristiques linguistiques les plus décrites et les plus saillantes des discours chatiens, certains phénomènes tels que l’usage de lexiques particuliers et diversifiés ne méritent pas moins d’attention. Nous nous proposons donc de décrire les usages des lexiques utilisés dans les chats par les différents types d’intervenants afin d’en déterminer les spécificités. Ainsi, nous nous demandons quelle est la diversité des lexiques et s’ils sont spécifiques à ce moyen de communication. Nous analyserons également les liens entre l’oral et l’écrit à travers l’usage de ces lexiques. Ceci étant, la réflexion que nous avons choisi de conduire dépasse le cadre de la description propre à une seule langue puisque nous nous intéressons comparativement au français, à l’espagnol et au polonais. Il est en effet intéressant de se demander si le langage du chat est un phénomène globalisant présentant des universaux linguistiques. Ainsi, la problématique de l’étude des lexiques englobera les questions suivantes : les langues française, espagnole et polonaise fonctionnent-elles de la même manière dans les chats ? Quels sont les phénomènes lexicaux récurrents et divergents d’une langue à l’autre ? Est-il possible de parler d’une identité de cybercommunauté chatienne sur le plan lexical ?

    ERayome, J.; Romig, S., LLNL

    1998-05-22

    The purpose of this paper is to describe recent trends CIAC has encountered while working with sites that have been compromised. Frequently, the intruders set up and run Internet Relay Chat (IRC) to exchange information and to show off their success at having compromised a site. Invariably, this protocol consumes bandwidth, uses CPU cycles and is a source of embarrassment for the site. This paper focuses on these negative aspects of IRC and concedes that one can cite numerous examples where IRC is used in a positive manner.

    Morphological and functional changes in the enteric nervous system (ENS) have been reported in inflammatory bowel disease. We examined the effects of inflammation on the expression of choline acetyltransferase (ChAT) and nNOS in the muscularis externae of two models of colonic inflammation, trinitrobenzene sulfonic acid (TNBS)-induced colitis, which models Crohn's disease-like inflammation, and DSS-induced colitis, which models ulcerative Colitis-like inflammation. In TNBS colitis, we observed significant decline in ChAT, nNOS, and protein gene product (PGP) 9.5 protein and mRNA levels. In DSS colitis, ChAT and PGP9.5 were significantly upregulated while nNOS levels did not change. The nNOS dimer-to-monomer ratio decreased significantly in DSS- but not in TNBS-induced colitis. No differences were observed in the percentage of either ChAT (31 vs. 33%)- or nNOS (37 vs. 41%)-immunopositive neurons per ganglia or the mean number of neurons per ganglia (55 ± 5 vs. 59 ± 5, P > 0.05). Incubation of the distal colon muscularis externae in vitro with different types of inflammatory mediators showed that cytokines decreased ChAT and nNOS expression, whereas H₂O₂, a component of oxidative stress, increased their expression. NF-κB inhibitor MG-132 did not prevent the IL-1β-induced decline in either ChAT or nNOS expression. These findings showed that TNBS- and DSS-induced inflammation differentially regulates the expression of two critical proteins expressed in the colonic myenteric neurons. These differences are likely due to the exposure of the myenteric plexus neurons to different combinations of Th1-type inflammatory mediators and H₂O₂ in each model.

    The objective of our research was to quantify the increased risk of suicide associated with registering in local hotels/motels. Medical examiner case files of suicide in King County, Washington, were reviewed for years 2002-2004. The incidence of suicide in local residents registering in local hotels/motels was 223/100,000 which is significantly greater than the incidence of suicide in the general population of King County (11.7/100,000 p Hotel/motel guests from outside Washington had a significantly reduced incidence of suicide (3.9/100,000 p = 0.002). The study results suggest that there is an increased risk of suicide in local residents who register in local hotel rooms.

  7. [Rooming-in history

    1999-01-01

    OBJECTIVE: To review the rooming-in facility for mother and child and the transformations in the perinatal care. METHOD: This is a bibliographic review with a content analysis from a historical point of view. OUTCOME: Until the beginning of this century, labor and birth were strictly a domestic event under the responsibility of women. When the hospitals began to offer new techniques they became the place of choice to treat all kinds of patients. This new way of treatment confined patients in hospitals away from their relatives and friends. Even newborn babies were to be left alone in nurseries away from their mothers, in order to be protected from any kind of infection. In the late 40s, researchers connected the mother-child separation at birth to some disadjustments in family relations and this led the way to a new research field. One of the innovations was a rooming-in facility for mother and child. This was first used as a trial whose intention was to re-empower the mother with her baby care. As a trial it ended and was only reborn in the 70s sponsored by WHO and UNICEF. CONCLUSIONS: Mother-child separation raises maternal insecurity, decreases breast feeding and deprives the baby from his mother's love and care. It has been already shown that children who are separated from their mothers at birth are more likely to be abandoned, hurt or abused. Thus it should be advisable to enroll health professionals in promoting mental and psychological health of mothers, babies and their families.

  12. Crafting a Democratic Enclave on the Cyberspace: Case Studies of Malaysia, Indonesia, and Singapore

    Directory of Open Access Journals (Sweden)

    Yangyue Liu

    2011-01-01

    Full Text Available As an antithesis of “authoritarian enclave” which has been well-established in the comparative politics literature, “democratic enclave” points to the institution of a state or the unambiguous regulatory space in society “where the authoritarian regime’s writ is substantively limited and is replaced by an adherence to recognizably democratic norms and procedures” (Gilley 2010. In this sense, the Internet space, embodied by information and communication technologies, has great potential to play such a role, since its “inherited” properties of decentralization and anonymity would inevitably breach the authoritarian rules. However, a closer look at three Southeast Asian states, Malaysia, Singapore and the “New Order” Indonesia whose regimes were characterized by authoritarianism when Internet was initially developed, reveals different trajectories. In the “New Order” Indonesia and Malaysia, the governments consciously left the Internet space uncontrolled; the online media developed independently, vibrantly, and professionally, especially in the Malaysian case; and there were strong connections between online and offline contentious politics. These elements made the Internet space in Indonesia and Malaysia a successful case of democratic enclave. Based on these criteria, however, the Internet space in Singapore has not achieved similar status. This paper analyses the different outcomes of enclave creation on the cyberspace among these countries. It argues that elite conflict and the strength of civil society are the two major factors that shape the differences. In this sense, the political contexts are of great importance for the understanding of Internet’s political impacts.

    Cri du Chat syndrome (CdC) is a chromosomal abnormality (deletion of short arm of chromosome 5) associated with intellectual disability and typical anatomical abnormalities. Research up to now focuses on the management of the disease during childhood. The longer lifespan of these patients warrants deeper investigations of how and if aging could be affected by the syndrome. We decided to focus on the association of the disease with proliferative disorders. Data on proliferative disorders in a cohort of 321 patients from Italian and German Cri du Chat databases were collected. A neoplasia was present in four patients (age 10-50 yrs), and a fifth patient developed a cholesteatoma during childhood. It is of interest that two cases had an early onset of the neoplasia as compared to the expected age of development in the general population. The chromosome region deleted in 5p does not contain genes whose haploinsufficiency is a well-known main cause of the proliferative disorders observed. We nonetheless believe that reporting even sporadic cases of proliferative disorders in CdC patients may increase our knowledge as to the natural history of the disease. In conclusion, available information suggests that surveillance for cancer development in CdC can follow the guidelines for the general population.

    2013-07-13

    Congenital vertical talus is a rare deformity of the foot which can cause substantial pain and disability. Its incidence is approximately 1 in 100,000 live births. It has an association with other neuromuscular abnormalities and identified genetic syndromes in 50% of cases [1-5]. This report presents a case of congenital vertical talus in an infant with Cri du Chat Syndrome (CdCS) which - to our knowledge - has not been previously reported. A 2 week-old Caucasian, male infant was referred for congenital feet abnormalities and a "clicky" hip at the post-natal baby check. The diagnosis was vertical talus of the right foot and oblique talus of the left foot. Treatment involved serial plaster casts in the "reverse-Ponseti" position until surgery 16 weeks later. The correction was maintained and the feet remain in good position at follow-up. General concern over the infant's development, failing to reach appropriate milestones, prompted paediatric referral. Genetic analysis was finally carried out, giving a diagnosis of Cri du Chat syndrome at two and a half years of age. In light of other reports of chromosomal anomalies causing congenital vertical talus, the learning point from this case is to investigate early for possible aetiologies, not only spinal/neuromuscular, but also those of a genetic basis.

    The Cri du Chat syndrome (SCdC / [OMIM #123450]) is a rare disease characterized by the deletion of the short arm of chromosome 5. The typical clinical features are the cat-like cry, microcephaly, a distinct facial phenotype and a severe psychomotor and mental retardation. The aim of this study was to provide an analysis on the data concerning the life quality and families assistance to whom have a child affected by Cri du Chat syndrome such as: the life's change of parents after the child's birth, the frequency of treatments, the collaboration between family and center of reference. We have also analyzed the improvement obtained, the type of school attended, the aide and the time spent at home in postprimary education. Through a questionnaire sent to 100 families, we have been picked up information on 76 patients. These families have to adapt to the reality of a child with a rare genetic disorder for which there are no pharmacological or surgical therapies. Therefore, it seems important to give information and tips for dealing with the disease and the early start of rehabilitation and educational therapy.

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

    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.

    We describe two advanced video analysis techniques, including video-indexed by voice annotations (VIVA) and multi-media indexing and explorer (MINER). VIVA utilizes analyst call-outs (ACOs) in the form of chat messages (voice-to-text) to associate labels with video target tracks, to designate spatial-temporal activity boundaries and to augment video tracking in challenging scenarios. Challenging scenarios include low-resolution sensors, moving targets and target trajectories obscured by natural and man-made clutter. MINER includes: (1) a fusion of graphical track and text data using probabilistic methods; (2) an activity pattern learning framework to support querying an index of activities of interest (AOIs) and targets of interest (TOIs) by movement type and geolocation; and (3) a user interface to support streaming multi-intelligence data processing. We also present an activity pattern learning framework that uses the multi-source associated data as training to index a large archive of full-motion videos (FMV). VIVA and MINER examples are demonstrated for wide aerial/overhead imagery over common data sets affording an improvement in tracking from video data alone, leading to 84% detection with modest misdetection/false alarm results due to the complexity of the scenario. The novel use of ACOs and chat Sensors 2014, 14 19844 messages in video tracking paves the way for user interaction, correction and preparation of situation awareness reports.

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

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

    Full Text Available A new tradition in the use of chatting communication technology with mobile phone (cell phone is more lively with the use of stickers. Stickers are used as a means to increase the emotion expressions of communication users. Current mobile phone technology, along with the development of high specifications (for visual depiction, is adequate to display complex visual. This prompts a new tradition that accepts even to be a new behavior in modern communication methods. Looking at this phenomenon, it is not impossible for an artist to open up the work area (creative economy and the creation of new business areas in the visual characters of Indonesian culture. This study used the chatting phenomenon with stickers to introduce the culture of the puppet characters with contemporary approach for young people around the world. The method carried out included the depiction of classification of facial expression emotions and collaboration with the approach of some common sticker visualizations. The result was then put into the classification of semiotic theory combining with simplified visual approach to obtain the appropriate visual characterstics of the puppet. Research also involved visual craft of the purwa puppet as visual character basis for character deformation of the contemporary puppet. Thus, the application of visual stickers can be used by users for communication functions.

    2005-10-01

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

    In face-to-face communications, to avoid sanctions and disapproval from others, people are more likely to hide negative aspects of their true self (such as socially undesirable personalities, minds, beliefs and consciousness) to avoid conflict with social norms and laws. The anonymity of cyberspace provides people a unique environment to behave more freely and openly with less restraint from the real word. Existing research related to online true self expression has mainly explored true self as an independent aspect of self. Regarding true self as a two-dimensional concept, this study investigates true self from the perspective of individuals' self-guide and identity reconstruction in both online and offline world. Using qualitative research methods, the current study investigates 57 participants through interviews and questionnaires. Content analysis reveals four factors that motivate people to express more true self (especially negative true self) when reconstructing their online identity and involve true self as a part of their self-guide in anonymous environment. By incorporating true self as an important part of individuals' self-guide and identity online, the current study advances self-discrepancy theory, making it more comprehensive for cyberspace. The results are also interpreted based on self-determination theory. The theoretical contributions of this study are discussed and practical implications are also presented.

    Imagine that you are blindfolded inside an unknown room. You snap your fingers and listen to the room's response. Can you hear the shape of the room? Some people can do it naturally, but can we design computer algorithms that hear rooms? We show how to compute the shape of a convex polyhedral room from its response to a known sound, recorded by a few microphones. Geometric relationships between the arrival times of echoes enable us to "blindfoldedly" estimate the room geometry. This is achieved by exploiting the properties of Euclidean distance matrices. Furthermore, we show that under mild conditions, first-order echoes provide a unique description of convex polyhedral rooms. Our algorithm starts from the recorded impulse responses and proceeds by learning the correct assignment of echoes to walls. In contrast to earlier methods, the proposed algorithm reconstructs the full 3D geometry of the room from a single sound emission, and with an arbitrary geometry of the microphone array. As long as the microphones can hear the echoes, we can position them as we want. Besides answering a basic question about the inverse problem of room acoustics, our results find applications in areas such as architectural acoustics, indoor localization, virtual reality, and audio forensics.

    To meet the needs of the new ISOLDE experiments, a new extension has been added to the facility's Building 170. The new extension to Building 170. Moving around the ISOLDE hall was almost like an obstacle course until now. The facility's Building 170 simply didn't have an inch to spare and the ISOLDE team's need to set up new experiments, whose installation could have created difficulties from the safety point of view, only exacerbated the problem. "We had ambitious plans to develop new experiments but no room for them", says Mats Lindroos, ISOLDE's technical coordinator. The only solution was to extend the existing building". This was how a new building saw the light of day. Measuring 24 metres long, 20 metres wide and 12 metres high, it is an extension to the existing Building 170 and should be ready for use this year. The new structure makes use of the existing infrastructure, with part of the end wall of Building 170 being kept as a support for steel platforms. The top of this wall had to be cut away ...

    WeChat represents one of the most popular smartphone-based applications for communication. Although the application provides several useful features that simplify daily life, a growing number of users spend excessive amounts of time on the application. This may lead to interferences with everyday life and even to addictive patterns of use. In the context of the ongoing discussion on Internet Communication Disorder (ICD), the present study aimed to better characterize the addictive potential of communication applications, using WeChat as an example, by examining associations between individual variations in tendencies towards WeChat addiction and brain structural variations in fronto-striatal-limbic brain regions. To this end levels of addictive tendencies, frequency of use and structural MRI data were assessed in n = 61 healthy participants. Higher tendencies towards WeChat addiction were associated with smaller gray matter volumes of the subgenual anterior cingulate cortex, a key region for monitoring and regulatory control in neural networks underlying addictive behaviors. Moreover, a higher frequency of the paying function was associated with smaller nucleus accumbens volumes. Findings were robust after controlling for levels of anxiety and depression. The present results are in line with previous findings in substance and behavioral addictions, and suggest a similar neurobiological basis in ICD.

    BACKGROUND WeChat is a convenient and popular social medium, and it seems to be an appropriate platform for education and management of patients. This study sought to identify usefulness in clinical control of cough-variant asthma (CVA). MATERIAL AND METHODS A randomized controlled trial was conducted among 80 CVA patients. After being assigned to either the traditional group (TG) or the WeChat group (WG), they received the same inhalation therapy, but patients in WG received additional education and instruction via our public account on the WeChat application. Questionnaires on asthma and chronic cough, data on pulmonary function, blood-related items, follow-up adherence, and Emergency Department (ED) visits were collected at the initial visit and at 3 months. RESULTS A total of 67 participants completed the trial for analysis. FEV1/predicted and FEV1/FVC were significantly increased in WG (pWeChat as part of treatment and management of CVA can help patients learn about their disease and medications, as well as improve disease control and therapy outcomes.
