    Moorman, Bridget A; Cockle, Richard A

    2013-01-01

    Financial pressures, an aging population, and a rising number of patients with chronic diseases, have encouraged the use of remote monitoring technologies. This usually entails at least one physiological parameter measurement for a clinician. Mobile telecommunication technologies lend themselves to this functionality, and in some cases, avoid some of the issues encountered with device integration. Moreover, the inherent characteristics of the mobile telecommunications infrastructure allow a coupling of business and clinical functions that were not possible before. Table I compares and contrasts some key aspect of device integration in and out of a healthcare facility. An HTM professional may be part of the team that acquires and/or manages a system using a mobile telecommunications technology. It is important for HTM professionals to ensure the data is in a standard format so that the interfaces across this system don't become brittle and break easily if one part changes. Moreover, the security and safety considerations of the system and the data should be a primary consideration in and y purchase, with attention given to the proper environmental and encryption mechanisms. Clinical engineers and other HTM professionals are unique in that they understand the patient/clinician/device interface and the need to ensure its safety and effectiveness regardless of geographical environment.

    2016-09-01

    Full Text Available The need for better support marketing decision on customers who are likely to leave a service provider for a competitor is very essential to the survival of most telecommunication firms. The application of logistic regression to the study of customer churn and retention decision in the Nigerian telecommunication industry falls into proactive methods, which helps in a better understanding of the needs of subscribers, to be able to predict their churn and retention decision in the industry and enhance better marketing strategies with a research driven policy guide for the operators in the industry. The purpose of this study is to ascertain the relevant drivers of customers` churn and retention in the growing Nigerian mobile telecommunication industry. Considering this issue, the logistic regression models have been used as the evaluating method. Four hundred and eight questionnaires have been used in this study. The population of this questionnaire consists of subscribers of mobile telecommunication in the six selected campuses of higher institution of learning in Lagos-state, Nigeria. The data collected was analysed by STATA 12 software. The results showed that the coefficients of mobile number portability (MNP services and dubious promotions are positive and significant. Furthermore, low coverage and unwanted calls and SMS are positive and significant. This implies that the better the availability of MNP services, the greater the likelihood of customers’ churn. More so, an increase in quality of calls provided by mobile telecom firms will increase the likelihood of customers’ loyalty by retention. The study recommends strong institutional measures for the overhaul of mobile services provision towards an improved service delivery in Nigeria.

  10. The association between socioeconomic status and exposure to mobile telecommunication networks in children and adolescents.

    Thomas, Silke; Heinrich, Sabine; Kühnlein, Anja; Radon, Katja

    2010-01-01

    A potential association between socioeconomic status (SES) and self-reported use of mobile phones has been investigated in a few studies. If measured exposure to mobile phone networks differs by SES in children, it has not yet been studied. Interview data of 1,481 children and 1,505 adolescents on participants' mobile phone use, socio-demographic characteristics and potential confounders were taken from the German MobilEe-study. Sociodemographic data was used to stratify participants into three "status groups" (low, middle, high). Using a personal dosimeter, we obtained an exposure profile over 24 h for each of the participants. Exposure levels during waking hours were expressed as mean percentage of the reference level. Children with a low SES were more likely to own a mobile phone (OR 2.1; 95% CI: 1.1-3.9) and also reported to use their mobile phone longer per day (OR 2.4; 95% CI: 1.1-5.4) than children with a high SES. For adolescents, self-reported duration of mobile phone use per day was also higher with a low SES (OR: 3.4; 95% CI: 1.4-8.4) compared with a high SES. No association between SES and measured exposure to mobile telecommunication networks was seen for children or adolescents. Mobile phone use may differ between status groups with higher use among disadvantaged groups. However, this does not result in higher overall exposure to mobile telecommunication networks. Whether short duration of own mobile phone use or the small numbers of participants with a low SES are causal, have to be investigated in further studies. (c) 2009 Wiley-Liss, Inc.

  11. Interference of mobile phones and digitally enhanced cordless telecommunications mobile phones in renal scintigraphy.

    Stegmayr, Armin; Fessl, Benjamin; Hörtnagl, Richard; Marcadella, Michael; Perkhofer, Susanne

    2013-08-01

    The aim of the study was to assess the potential negative impact of cellular phones and digitally enhanced cordless telecommunication (DECT) devices on the quality of static and dynamic scintigraphy to avoid repeated testing in infant and teenage patients to protect them from unnecessary radiation exposure. The assessment was conducted by performing phantom measurements under real conditions. A functional renal-phantom acting as a pair of kidneys in dynamic scans was created. Data were collected using the setup of cellular phones and DECT phones placed in different positions in relation to a camera head to test the potential interference of cellular phones and DECT phones with the cameras. Cellular phones reproducibly interfered with the oldest type of gamma camera, which, because of its single-head specification, is the device most often used for renal examinations. Curves indicating the renal function were considerably disrupted; cellular phones as well as DECT phones showed a disturbance concerning static acquisition. Variable electromagnetic tolerance in different types of γ-cameras could be identified. Moreover, a straightforward, low-cost method of testing the susceptibility of equipment to interference caused by cellular phones and DECT phones was generated. Even though some departments use newer models of γ-cameras, which are less susceptible to electromagnetic interference, we recommend testing examination rooms to avoid any interference caused by cellular phones. The potential electromagnetic interference should be taken into account when the purchase of new sensitive medical equipment is being considered, not least because the technology of mobile communication is developing fast, which also means that different standards of wave bands will be issued in the future.

  13. Tariff-Mediated Network Effects versus Strategic Discounting: Evidence from German Mobile Telecommunications

    Zucchini, Leon; Claussen, Jörg; Trüg, Moritz

    2013-01-01

    Mobile telecommunication operators routinely charge subscribers lower prices for calls on their own network than for calls to other networks (on-net discounts). Studies on tariff-mediated network effects suggest this is due to large operators using on-net discounts to damage smaller rivals. Alternatively, research on strategic discounting suggests small operators use on-net discounts to advertise with low on-net prices. We test the relative strength of these effects using data on tariff setti...

  14. An Analytic Hierarchy Process Analysis: Application to Subscriber Retention Decisions in the Nigerian Mobile Telecommunications

    Adebiyi Sulaimon Olanrewaju

    2015-12-01

    Full Text Available The introduction of mobile number portability (MNP in the Nigerian telecommunications industry has brought a new challenge for mobile operators. This study investigates the use of Analytic Hierarchy Process (AHP in customer retention decisions in the Nigerian telecommunication industry using a cross-sectional survey design. Primary data were obtained through questionnaires administered to 480 mobile telecommunications subscribers in six tertiary institutions located in Lagos State, Nigeria. These educational institutions were chosen using a multistage sampling technique. Of 438 questionnaires received from subscribers, 408 were valid. Based on this sample data an AHP model was built to assess the determinants of customer retention decisions. Next, eigen values, an eigen vector and maximum lambda (λMax were obtained using the AHP analysis for the matrices. This analysis shows that customers considered call quality as the important in the retention decision. We conclude that AHP is a meaningful tool for determining what motivates retention decisions, that can help network operators formulate effective customer retention strategies.

    Full Text Available This paper considers the narratives in mobile phone commercials during a period of unprecedented market expansion. How was the fastest growing global sector in 2012 sold to consumers in different countries and cultures, and how have mobile brands, that differentiate themselves on service personality, conveyed their uniqueness within different global markets? The following research identifies regional characteristics in genres of mobile telecommunications advertising, including motivations and modes of address deployed for different geographic territories. By tracking narrative patterns through a significant sample of mobile commercials we have chartered the variety of message types, identified how brands have used localised customer insights and adjusted to regional variations. Conclusions highlight storytelling techniques used within glocal creative strategies of multinational campaigns, plus the nuances and patterns of targeted and generic campaigns.

  16. Discourse and policy making on consumer protection in the areas of mobile telecommunication and tanning.

    Schweikardt, Christoph; Rosentreter, Michael; Gross, Dominik

    2012-01-01

    Perceived health risks from electromagnetic fields in mobile telecommunication and from UV radiation in tanning have become regulation issues in Germany during the last decade. Health risk messages from government expert bodies and the main stakeholders in these areas as well as subsequent consumer protection policy making are investigated. Publications and websites of government expert bodies and the main stakeholders as well as debates in Federal Parliament were analysed to compare argumentation patterns and parliamentary decision-making processes. In both areas, the public received competing health risk messages from the industries and their critics. As a government expert body, the Federal Office for Radiation Protection (BfS) held the view that alleged health risks from electromagnetic telecommunication were not proven, and propagated the precautionary principle. This opinion did not endanger the agreement of 2001 between the government and mobile telecommunication operators. After the failure to obtain voluntary commitment from the tanning industry, by contrast, the BfS recommended stricter consumer protection legislation, which was subsequently implemented. The BfS was in a key position to demand the prerogative of interpretation concerning mutually excluding health risk messages and to provide the argumentation which led the way to non-ionic radiation health protection measures.

  17. Investigating the quality of video consultations performed using fourth generation (4G) mobile telecommunications.

    Caffery, Liam J; Smith, Anthony C

    2015-09-01

    The use of fourth-generation (4G) mobile telecommunications to provide real-time video consultations were investigated in this study with the aims of determining if 4G is a suitable telecommunications technology; and secondly, to identify if variation in perceived audio and video quality were due to underlying network performance. Three patient end-points that used 4G Internet connections were evaluated. Consulting clinicians recorded their perception of audio and video quality using the International Telecommunications Union scales during clinics with these patient end-points. These scores were used to calculate a mean opinion score (MOS). The network performance metrics were obtained for each session and the relationships between these metrics and the session's quality scores were tested. Clinicians scored the quality of 50 hours of video consultations, involving 36 clinic sessions. The MOS for audio was 4.1 ± 0.62 and the MOS for video was 4.4 ± 0.22. Image impairment and effort to listen were also rated favourably. There was no correlation between audio or video quality and the network metrics of packet loss or jitter. These findings suggest that 4G networks are an appropriate telecommunication technology to deliver real-time video consultations. Variations in quality scores observed during this study were not explained by the packet loss and jitter in the underlying network. Before establishing a telemedicine service, the performance of the 4G network should be assessed at the location of the proposed service. This is due to known variability in performance of 4G networks. © The Author(s) 2015.

    Prlic, I.; Hajdinjak, M.; Radalj, Z.; Suric, M.

    2003-01-01

    Modern radio telecommunications are spreading through our civilisation like undesired wind. This new harmless technologies are pushed into the hands of our youngest population, children, in the way that nobody is aware of the possible social disaster which can be released if there will be no control over the harmful technology overflow. The deep ecology philosophy states that not only humans have the right to guide over the earth future but that whole biota living in given habitat and everything non-organic in the nature have this right too. They are suddenly suffering enormous artificial energy overflow. The radio communications are spreading over our heads for more than one hundred years. Humans were trying to find the harm or benefit from that powerful tool. Till today, the benefit was obvious and there was no health damage found which can be directly connected to the radio telecommunication energies produced. Though, every day humans are producing new devices, which produce more harmful electromagnetic fields all around us. Some of us are concerned, not because we are feared from the direct harm but because we are concerned about the influence through our habitat, which will affect our future at the end. That is why we have decided to perform and discuss measurements on the sites, which are not really inhabited with humans but which are important from the ecological point of view. This approach can lead us to some new results and conclusions and lead our knowledge towards even more harmless thinking. That simply means that humans have to take responsibility not only for themselves but for everything that exists on the planet. The use of mobile telecommunications is just one of the responsibilities. (author)

  1. Design and control strategy for a hybrid green energy system for mobile telecommunication sites

    Okundamiya, Michael S.; Emagbetere, Joy O.; Ogujor, Emmanuel A.

    2014-07-01

    The rising energy costs and carbon footprint of operating mobile telecommunication sites in the emerging world have increased research interests in green technology. The intermittent nature of most green energy sources creates the problem of designing the optimum configuration for a given location. This study presents the design analysis and control strategy for a cost effective and reliable operation of the hybrid green energy system (HGES) for GSM base transceiver station (BTS) sites in isolated regions. The design constrains the generation and distribution of power to reliably satisfy the energy demand while ensuring safe operation of the system. The overall process control applies the genetic algorithm-based technique for optimal techno-economic sizing of system's components. The process simulation utilized meteorological data for 3 locations (Abuja, Benin City and Sokoto) with varying climatic conditions in Nigeria. Simulation results presented for green GSM BTS sites are discussed and compared with existing approaches.

  3. Assessment of renewable energy technology and a case of sustainable energy in mobile telecommunication sector.

    Okundamiya, Michael S; Emagbetere, Joy O; Ogujor, Emmanuel A

    2014-01-01

    The rapid growth of the mobile telecommunication sectors of many emerging countries creates a number of problems such as network congestion and poor service delivery for network operators. This results primarily from the lack of a reliable and cost-effective power solution within such regions. This study presents a comprehensive review of the underlying principles of the renewable energy technology (RET) with the objective of ensuring a reliable and cost-effective energy solution for a sustainable development in the emerging world. The grid-connected hybrid renewable energy system incorporating a power conversion and battery storage unit has been proposed based on the availability, dynamism, and technoeconomic viability of energy resources within the region. The proposed system's performance validation applied a simulation model developed in MATLAB, using a practical load data for different locations with varying climatic conditions in Nigeria. Results indicate that, apart from being environmentally friendly, the increase in the overall energy throughput of about 4 kWh/$ of the proposed system would not only improve the quality of mobile services, by making the operations of GSM base stations more reliable and cost effective, but also better the living standards of the host communities.

    Full Text Available The telecommunication industry is one of the service industries that is most affected by the problem of subscribers’ churn. Although several techniques have been used to predict customer churn in developed countries, many of those studies used secondary data which are not readily available in Nigeria for researchers. This study investigates how Markov chains help in modelling and predicting the customer churn and retention rate in the Nigerian mobile telecommunication industry. The data generated through the survey were input in the Windows-based Quantitative System for Business (WinQSB for analysis. The results reveal that in the study area MTN has the highest retention rate (86.11%, followed by GLO (70.51%, Airtel (67%, and Etisalat (67.5%. This result has implications for telecom firms’ strategies for competitive advantage in particular and survival in general.

  10. The universal service in the future of network-type industries: telecommunications, electricity, postal services

    Bremond, Celine Clelia

    2003-01-01

    The notion of universal service emerged in the European regulation of the telecommunications sector, and can be applied to all network-type industries. Public monopolies have been put into question again. The introduction of deregulation and competitiveness were expected to improve the service provided to the end consumer, but this deregulation has been also put into question again for matters of universality and equity. Then the issue of financing of these services emerges. The aim of this research thesis is therefore to identify which funding modes can be optimal, and to identify a general methodology for all network-type industries. In the first part of this research thesis, the author studies the cost of universal service obligations. She explains the general methodology of calculation of this cost, and reports this calculation while taking indirect benefits of the operator into account. In a second part, she studies the modalities of financing thus calculated cost by describing the different possible modalities, their benefits and drawbacks, and by presenting a comparison between these methodologies according to three criteria: those set by the European Commission, welfare, and applicability. For these different topics, the author takes all experiments and recent developments into account. These experiments and developments are noticed in different countries: USA, Australia, UK, Sweden, Netherlands, Germany, Belgium, Italy, France

    2008-11-04

    Despite the increase of mobile phone use in the last decade and the growing concern whether mobile telecommunication networks adversely affect health and well-being, only few studies have been published that focussed on children and adolescents. Especially children and adolescents are important in the discussion of adverse health effects because of their possibly higher vulnerability to radio frequency electromagnetic fields. We investigated a possible association between exposure to mobile telecommunication networks and well-being in children and adolescents using personal dosimetry. A population-based sample of 1.498 children and 1.524 adolescents was assembled for the study (response 52%). Participants were randomly selected from the population registries of four Bavarian (South of Germany) cities and towns with different population sizes. During a Computer Assisted Personal Interview data on participants' well-being, socio-demographic characteristics and potential confounder were collected. Acute symptoms were assessed three times during the study day (morning, noon, evening).Using a dosimeter (ESM-140 Maschek Electronics), we obtained an exposure profile over 24 hours for three mobile phone frequency ranges (measurement interval 1 second, limit of determination 0.05 V/m) for each of the participants. Exposure levels over waking hours were summed up and expressed as mean percentage of the ICNIRP (International Commission on Non-Ionizing Radiation Protection) reference level. In comparison to non-participants, parents and adolescents with a higher level of education who possessed a mobile phone and were interested in the topic of possible adverse health effects caused by mobile telecommunication network frequencies were more willing to participate in the study. The median exposure to radio frequency electromagnetic fields of children and adolescents was 0.18% and 0.19% of the ICNIRP reference level respectively. In comparison to previous studies this is one of

  13. Effect of call-clubs to institute local network effects in mobile telecommunication and its′ implications on brand loyalty

    Karunarathne E. A .C. P

    2017-03-01

    Full Text Available As a result of rapid technological advancements in the mobile telecommunication industry, many firms have set their strategies to target larger customer bases since it forecasts extensive future profit generation. Due to severe competition, while employing successful customer loyalty strategies, customer locked-in strategies are also commonly used in the telecommunication industry to retain their customers within the firm. Call-clubs benefits are one of the commonly used strategies used to create local network effects in the mobile telecommunication market place. Thus, this paper targets to provide insight on the implication of subscriber’s involvement in call-clubs on their loyalty towards service providers. A survey based quantitative approach was followed for this study and the data was gathered through a structured off-line questionnaire from randomly selected mobile users in Sri Lanka. Based on collected valid responses, analysis was carried out to answer the designed research hypotheses and structural equation modelling techniques were mainly used for statistical analysis. As per the analysis, research model shows a fairly high level of explanatory power with customer loyalty and perceived call-clubs benefits which indicate customers′ preference towards the service provider when most frequently contacting parties are using the same network. Further analysis was carried out to investigate the moderating effect on call-clubs benefits and customer loyalty relationships due to two main technological advancements; namely, Internet based voice calling facility and multiple connection access facility. Based on the analysis results recommendations were made to track the value of call-clubs strategies accordingly.

  14. Interplay between telecommunications and face-to-face interactions: a study using mobile phone data.

    Calabrese, Francesco; Smoreda, Zbigniew; Blondel, Vincent D; Ratti, Carlo

    2011-01-01

    In this study we analyze one year of anonymized telecommunications data for over one million customers from a large European cellphone operator, and we investigate the relationship between people's calls and their physical location. We discover that more than 90% of users who have called each other have also shared the same space (cell tower), even if they live far apart. Moreover, we find that close to 70% of users who call each other frequently (at least once per month on average) have shared the same space at the same time--an instance that we call co-location. Co-locations appear indicative of coordination calls, which occur just before face-to-face meetings. Their number is highly predictable based on the amount of calls between two users and the distance between their home locations--suggesting a new way to quantify the interplay between telecommunications and face-to-face interactions.

  18. Mobility, Emotion, and Universality in Future Collaboration

    Chignell, Mark; Hosono, Naotsune; Fels, Deborah; Lottridge, Danielle; Waterworth, John

    The Graphical user interface has traditionally supported personal productivity, efficiency, and usability. With computer supported cooperative work, the focus has been on typical people, doing typical work in a highly rational model of interaction. Recent trends towards mobility, and emotional and universal design are extending the user interface paradigm beyond the routine. As computing moves into the hand and away from the desktop, there is a greater need for dealing with emotions and distractions. Busy and distracted people represent a new kind of disability, but one that will be increasingly prevalent. In this panel we examine the current state of the art, and prospects for future collaboration in non-normative computing requirements. This panel draws together researchers who are studying the problems of mobility, emotion and universality. The goal of the panel is to discuss how progress in these areas will change the nature of future collaboration.

  19. The Ongoing Accomplishment of the Mobile Telecommunication: An Ethnomethodological Study of “Talking on a Mobile Phone”

    Chia-Rong Tsao

    2015-07-01

    Full Text Available This paper attempts to explore the practices of “talking on a mobile phone” through the ethnomethodological approach. Instead of paying attention to the influences of the prevalence of mobile phones, this paper focuses on the ongoing accomplishment of the practices of cellphone-using. This paper contends that the mobile phone users accomplish the practices of “talking on a mobile phone” continuously by methods such as “reading hermeneutically”, “embodying”, “the documentary method of interpretation”, and “accounting reasonably”, etc. Users not only take these methods for granted, but also see but unnoticed what they really do by these cellphone-using practices. The practices identify and reproduce reflexively the structural influences brought by the prevalence of mobile phones while accomplishing the process of “talking on a mobile phone”.

  2. Outflow dynamics in modeling oligopoly markets: the case of the mobile telecommunications market in Poland

    Sznajd-Weron, Katarzyna; Weron, Rafał; Włoszczowska, Maja

    2008-11-01

    In this paper we introduce two models of opinion dynamics in oligopoly markets and apply them to a situation where a new entrant challenges two incumbents of the same size. The models differ in the way in which the two forces influencing consumer choice—(local) social interactions and (global) advertising—interact. We study the general behavior of the models using the mean field approach and Monte Carlo simulations and calibrate the models using data from the Polish telecommunications market. For one of the models criticality is observed—below a certain critical level of advertising the market approaches a lock-in situation, where one market leader dominates the market and all other brands disappear. Interestingly, for both models the best fits to real data are obtained for conformity level p \\in (0.3,0.4) . This agrees very well with the conformity level found by Solomon Asch in his famous social experiment.

  4. Environmental Discourses in Organizations: the Case of a Brazilian Mobile Telecommunications Company

    Alexandre de Pádua Carrieri

    2007-09-01

    Full Text Available This paper examines the discourse configurations on the environmental theme in business organizations and its relevance to the understanding of the inclusion of ecological discourses in the discourses of organizational members. A case study into a Brazilian telecommunications company offers empirical evidence. It begins with the understanding that organizations adopt several strategies in an attempt to disseminate a certain environmental discourse. As these efforts share space with other pressures, a fragmented discourse emerges. In this paper, the pressures of the environmental theme on organizations are discussed in order to understand this process. The second part of the argument focuses on the context of the case study – Brazilian organizations – and, afterwards, the third part deals with ecological discourses in their insertions in organizational interests. The data of the case study were collected through documental research and 40 semi-structured interviews. The analysis was applied based on Discourse Analysis. In conclusion, an ambiguous discourse configuration was shown that offer elements for the understanding that philanthropy, legal obligation and organizational competitiveness need to be used together to offer legitimacy to the theme of environmental responsibility in business organizations.

  5. Antecedents of Behavioral Intention to Use Mobile Telecommunication Services: Effects of Corporate Social Responsibility and Technology Acceptance

    Sanghoon Lee

    2015-08-01

    Full Text Available The concepts of corporate social responsibility (CSR and user experience have been identified as core determinants of the success of service providers. Accordingly, practitioners and researchers have investigated the effects of service providers’ CSR and user experience on behavioral intention to use a particular service. Based on the importance of these concepts, the current study integrates subjective dimensions of CSR with the technology acceptance model (TAM to explore whether the CSR efforts of mobile telecommunication services providers and the service acceptance of their customers have significant effects on behavioral intention to use a service. We apply structural equation modeling and find that two factors from the TAM (i.e., usefulness and ease of use as well as economic, social, and environmental responsibility are significantly related to customer attitude and satisfaction. Moreover, our results show that there are significantly positive relationships between customer attitude and behavioral intention to use a service, as well as between customer satisfaction and intention. Practical and theoretical implications along with notable limitations of the current study are presented.

  7. German private mobile telecommunication research program. Effects of a) low-frequency magnetic fields, b) GSM mobile telecommunication signals, c) UMTS signals on the spontaneous leukemia rate of AKR mice

    2006-01-01

    Since the introduction of private mobile telecommunication about 10 years ago, there is a worldwide discussion about the possible adverse health effects of such highfrequency electromagnetic fields (EMF). Main concerns are regarding the possible cancerogenic or promoting effect of mobile phones and base stations. The insecurity of the public is increased by the continuous development of new techniques and introduction of new systems (e.g. wireless LAN, UMTS), for which insufficient data are available about their possible health hazards. This project's aim was therefore to investigate if chronic exposure to EMF of the UMTS-standard will influence leukaemia or the development of solid tumors in an animal model. The experiment was performed with AKR mice, which is an accepted animal model for leukaemia. With high probability, these mice develop the disease within their lifespan, so that the time course of the onset of leukaemia, bodyweight, blood picture, time of survival, and pathological examinations were the endpoints of the investigation. 160 female AKR/J mice were exposed or sham-exposed for 24 hours per day to EMF of the UMTS-standard (0.4 W/kg SAR). Additionally, 33 animals were kept as cagecontrols. For this experiment special radial waveguides were constructed and built which have a low SAR variability. All experiments were performed in a blinded fashion. The only significant difference between exposed and sham-exposed mice was a higher survival rate of exposed animals. However, the number of ill animals, the mean survival time and the severity code of the disease did not differ between the experimental groups. Animals of the cage-control group had a significant lower growth rate compared to animals kept in the radial waveguides, likely the cause of differences in the method of food supply. The results of this study don't show any negative effects of the exposure. The results do not show any negative effects of exposure for months to EMF at levels 5-fold the

  11. Mobile heterotopia: movement, circulation and the function of the university

    Bradley Rink

    Full Text Available This paper explores the function of the university through the lens of mobility as seen from a South African perspective. Understanding the role of the university as one that requires the movement and circulation of academic bodies in the form of students and staff, and bodies of academic knowledge in the form of teaching, research and academic content, I use a theoretical framework from the interdisciplinary field of mobilities in order to understand the role of movement in the university and to highlight what is ruptured and catalysed by frictions enacted through power geometry, austerity and disruption. Sighted from the perspective of the University of the Western Cape in South Africa, this paper poses a series of provocations that reveal the obligations of presence that comprise the production and transfer of knowledge in the twenty-first-century university. I discuss how disruption and austerity, amongst other embedded mobility limitations, impact on the multiple/intersecting universes of the university; how the austere and disrupted university influences our engagement at various scales from local to global; and, finally, how disruption and austerity act to fix academic bodies in place even as they may allow virtual mobility to replace the face-to-face engagement that is the hallmark of the academic project. This paper demonstrates the critical role of mobility in the institution of the university and concludes that the university is a form of Foucauldian heterotopia mobilising diverse academic bodies and bodies of knowledge.

  12. Investigating Daily Mobile Device Use Among University Students in Indonesia

    Pratama, Ahmad R.

    2018-03-01

    This study investigates daily mobile device use among Indonesian university students by using survey data collected in the first quarter of 2016. The data show that 55.49% of the students spend more than five hours a day on their mobile devices. OLS regression analysis shows that female students, owners of the most expensive smartphone or tablet, and those who access social media apps and play mobile games frequently are more likely to spend more time on their mobile devices each day. Contrary to that, those who consider themselves as laggards are less likely to do so. The findings in this study help better understand how university students in Indonesia use their mobile device and lay a foundation as part of a larger research agenda about the relationship between mobile technology and education in Indonesia.

    Full Text Available The advantages of mobile technologies have not been lost on higher education institutions, and they have tried to provide educational services through the use of mobile learning management system (LMS. However, offering such services does not necessarily mean that the students will adopt the new technology. Thus, the purpose of this study was to examine what factors facilitate and hinder the students’ adoption of the mobile campus. The study was based on the diffusion of innovation model and compared the perceptions of mobile LMS users and nonusers. Eighty-five students in a cyber university responded to the survey, and the results revealed that even though nonusers perceived the advantages of using mobile LMS, they did not adopt the system because of its complexity and resistance. A discussion and the implications for further development of mobile LMS followed.

    2006-04-01

    In large hospitals, collaborative clinical practice is currently emphasized, with members of various departments expected to work as a team. The importance of accurate communication among the team members is of utmost importance. To improve such communication, the introduction of mobile voice communication systems has received much attention in Japan. Shimane University Hospital also introduced a Personal Handy-phone System (PHS) for doctors. In the traditional setting, much time was wasted searching for doctors through multiple calls on fixed-line telephones. In order to measure the effectiveness of our system, the change in the number of calls made on fixed-line telephones before and after PHS installation was compared. The total number of calls was reduced by more than 35%, and the number of calls to the wards on weekdays was reduced by half. Mobile telecommunication systems with small output power, such as PHS, are known to cause little interference with medical devices which makes it possible to use mobile voice communication safely in hospitals. The improvement in communication by this systems resulted in an improvement in labor efficiency.

    2014-01-01

    The widespread adoption of smart phones and tablet computers has the potential to revolutionize the way in which educational material is shared with the general public. As part of the outreach effort for the CANDELS survey, we have developed a free interactive astronomy education application named Hubble Universe for iPad and iPhone devices. The application focuses on extragalactic science topics related to the CANDELS legacy survey, which is documenting galaxy evolution in the early universe. I will provide an overview of the application, which contains a wide range of interactive content, including 3D models of astrophysical phenomenon, informative diagrams and computer simulations. I will discuss how the application can be used to enhance classroom learning both by providing a database of interactive media and by encouraging students to explore astronomical topics away from traditional settings like the classroom or the desktop computer.

    Full Text Available The workplace in the modern world continues to demand higher qualifications and refined competencies. In the recent past, workers would respond to such demands through learning by correspondence. When the Internet and e-Learning emerged, it received widespread accolade as a solution to the challenges experienced by distant learners. The technology was also seen as an opportunity for educational institutions to leverage their technological uptake to benefit regular students. However, desktop computers and Internet connectivity, which were the drivers of e-learning technologies, were expensive, bulky and scarce. So when mobile technologies emerged, educationist saw an opportunity for addressing the limitations associated with correspondence, “e” and tethered learning. Mobile devices being cheap, portable and reliable received widespread acceptance and possession. So, educators, hardware designers and program developers started to design hardware and applications that would infuse learning content into the devices. The purpose of this review is to demonstrate the potential of mobile technologies in the education market place, highlighting global initiatives and trends. The paper will also review how universities around the world, Africa and in Kenya have oriented themselves for learning with mobile technologies. The study was a documentary analysis of virtual documents stored electronically for access through the Internet, text books, archival repositories and encyclopedias. The study observed a significant high global mobile ownership and usage rates, but was able to demonstrate that despite its pedagogical advantages, the use of the technology for learning purposes at university level is still at the infantry.

    1996-03-01

    An application of various mobile communication systems to the electric power telecommunication network has been investigated. Among these, the customer information network by PHS (personal handy-phone system) has been proposed. Although great numbers of base stations are required for PHS, it can be applied as the customer information network by connecting to the power controller developed by the Central Research Institute of Electric Power Industry. The geostationary satellite telecommunication has been positively utilized by the electric power industry since the Hanshin-Awaji Great Earthquake. It can be used as the customer information network in the future. Since the radio access is a one-way communication, it cannot be applied to the electric power telecommunication network at present. It can be applied to the simple message communication or relatively low-speed data communication through the two-way communication. Public ground mobile telecommunication in the future includes various mobile telecommunication systems. To start the operation in 2000, the ITU (International Telecommunication Union) is making specifications common in the world. It is required to investigate the utilization as multipurpose systems. The network for PHS can be applied to the telecommunication network without optical cable. 20 refs., 5 figs., 3 tabs.

  13. Combining Diffusion Models and Macroeconomic Indicators with a Modified Genetic Programming Method: Implementation in Forecasting the Number of Mobile Telecommunications Subscribers in OECD Countries

    Konstantinos Salpasaranis

    2014-01-01

    Full Text Available This paper proposes a modified Genetic Programming method for forecasting the mobile telecommunications subscribers’ population. The method constitutes an expansion of the hybrid Genetic Programming (hGP method improved by the introduction of diffusion models for technological forecasting purposes in the initial population, such as the Logistic, Gompertz, and Bass, as well as the Bi-Logistic and LogInLog. In addition, the aforementioned functions and models expand the function set of hGP. The application of the method in combination with macroeconomic indicators such as Gross Domestic Product per Capita (GDPpC and Consumer Prices Index (CPI leads to the creation of forecasting models and scenarios for medium- and long-term level of predictability. The forecasting module of the program has also been improved with the multi-levelled use of the statistical indices as fitness functions and model selection indices. The implementation of the modified-hGP in the datasets of mobile subscribers in the Organisation for Economic Cooperation and Development (OECD countries shows very satisfactory forecasting performance.

  18. Mobile telecommunications and health: report of an investigation into an alleged cancer cluster in Sandwell, West Midlands.

    Stewart, Antony; Rao, Jammi N; Middleton, John D; Pearmain, Philippa; Evans, Tim

    2012-11-01

    Residents of one street expressed concern about the number of incident cancers, following the installation of a nearby mobile phone base station. The investigation explored whether the base station could be responsible for the cancers. Data were collected from residents' medical records. GPs and oncologists provided further information. Ward-level cancer incidence and mortality data were also obtained, over four three-year time periods. A total of 19 residents had developed cancer. The collection of cancers did not fulfil the criteria for a cancer cluster. Standardized mortality ratios (SMRs) for all malignant neoplasms (excluding non-melanoma skin cancers) in females (1.38 (95% CI, 1.08-1.74)) and all persons (1.27 (CI, 1.06-1.51)) were significantly higher than in the West Midlands during 2001-3. There were no significant differences for colorectal, female breast and prostate cancers, for any time period. Standardized incidence ratios (SIRs) for non-melanoma skin cancers in males and all persons was significantly lower than in the West Midlands during 1999-2001, and significantly lower in males, females and all persons during 2002-4. We cannot conclude that the base station was responsible for the cancers. It is unlikely that information around a single base station can either demonstrate or exclude causality.

    This book contains the proceedings of the first international symposium devoted to research on the evaluation and planning of new person-to-person telecommunication systems. It was sponsored by NATO's Special Programme Panel on Systems Science and took place, in September 1977, at the University of Bergamo in the north of Italy. Telecommunication systems which provide for communication be­ tween people, rather than computers or other instruments, are of two kinds. There are mass communication systems (broadcast radio and television) and interpersonal systems (for example, the telephone and Telex) which join together individuals or small groups. Here we have included in the interpersonal category certain systems for re­ trieving information from computers, essentially those systems in which the role of the computer 1s primarily to act as a store and to identify that information which best fits a user's request. (This excludes management information systems in which the computer performs important transformat...

  4. Mobile Attendance Checking System on Android Platform for Kazakhstani University

    Saparkhojayev, N.; Shakhov, E.; Mailybayev, Y.

    2016-04-01

    In the 21st century-the century of Information Technology, it is difficult to imagine life without any gadgets: phones, tablets, computers, laptops, and so on. Today, smartphones and tablets are becoming popular, and thus their operating systems become popular too. Android is designed for low-power devices that run on battery power at full capacity, using all of its services, such as cameras, lights, GPS navigation, Wi-Fi, etc. In Kazakhstani universities, the process of checking students’ attendance is one of the important issues, because final grade evaluation of students is based on their total number of appearances and their grades during the whole semester. This raises the question of having some tool to control students’ attendance. There are many possible ways of controlling attendance: there are many examples when universities prefer to control attendance by the use of paper sheet, and some universities prefer to use two-stage way of controlling attendance: firstly, teachers and professors use paper sheet for checking students’ attendance and after this, they fill out these information into a system manually. However, this is not an efficient way since there will be spent much of time for calling students names and putting marks like “presence” or “absence” if the class is a lecture class, and in this class at least 5 groups are presented. Furthermore, some students may call his/her friend as “presence” nevertheless to the fact that this student is currently absent. After taking into consideration all these issues and the fact that many gadgets use Android platform, authors of the following research paper decided to create a mobile system that makes easier to check students’ attendance automatically, and this system is implemented in Almaty Management University, Kazakhstan. The system is based on Android platform, and in this paper, details of this system are presented.

  6. Exploring Diverse Effects of Four Types of Mobility on University Entrepreneurship

    Satoko Yasuda

    2016-12-01

    Full Text Available This study explores the mechanism by which mobility influences university entrepreneurship through an empirical analysis of Japanese scientists working for the University of Tokyo. It presents theory-driven typology of mobility and applies it to the knowledge-transfer context.  First, this paper subdivides previously-studied mobility into four types – job mobility (JM, sector mobility (SM, international mobility (IM, and the educational background mobility (EBM. Then, it empirically shows that both JM and IM have positive and significant correlation with university entrepreneurship, whereas neither SM nor EBM does. Based on the result, this study discusses that JM and IM accelerate the formation of skills necessary for the commercialization of university research; however, SM and EBM may have no impact on it.

  14. Evolution and convergence in telecommunications

    Radicella, S; Grilli, D [Abdus Salam ICTP, Trieste (Italy)

    2002-12-15

    These lectures throw a spotlight on different aspects of the evolution of telecommunications networks, namely on the various facets of service and network convergence. The last years progress in data and telecommunications technologies, such as P-based networks, and the enormous potential of mobile communication systems and users' demands for comprehensive and network-independent have led to a convergence of data and telecommunications infrastructures in many aspects. In order to help the reader to an easier understanding of the phenomenon convergence, in the first two parts of this volume the evolution of the basic technologies is described one by one. This is done briefly and is focused on the principle topics, just to build a basis for the third part devoted to problems of convergence in telecommunications. These notes are addressed to those readers, who in a quick overview want to be informed on the future service and network landscape. The notes are equally suited for professionals with the desire to extend their horizon as well as for students looking for an introduction into telecommunications under more general aspects. The authors clearly understand the difficulties in writing a book devoted to the evolution in telecommunications. Today, telecom landscape varies at very high speed. Every few months new network technologies, new products and new services are developed. Attempts to present them in time can be accessible only for magazine publications or contributions to conferences. Therefore, in a number of areas, such as Voice over IP and new switching technologies not much more than the starting point of new paradigms is described. However, the content is up-to-date to a degree, that the phenomenon convergence can be fully understood. Partially, these notes are based on a number of lecture courses that were delivered during recent ICTP winter schools devoted to multimedia and digital communications.

In order to help the reader to an easier understanding of the phenomenon convergence, in the first two parts of this volume the evolution of the basic technologies is described one by one. This is done briefly and is focused on the principle topics, just to build a basis for the third part devoted to problems of convergence in telecommunications. These notes are addressed to those readers, who in a quick overview want to be informed on the future service and network landscape. The notes are equally suited for professionals with the desire to extend their horizon as well as for students looking for an introduction into telecommunications under more general aspects. The authors clearly understand the difficulties in writing a book devoted to the evolution in telecommunications. Today, telecom landscape varies at very high speed. Every few months new network technologies, new products and new services are developed. Attempts to present them in time can be accessible only for magazine publications or contributions to conferences. Therefore, in a number of areas, such as Voice over IP and new switching technologies not much more than the starting point of new paradigms is described. However, the content is up-to-date to a degree, that the phenomenon convergence can be fully understood. Partially, these notes are based on a number of lecture courses that were delivered during recent ICTP winter schools devoted to multimedia and digital communications

  17. Mobile Abuse in University Students and profiles of victimization and aggression.

    Polo Del Río, Mª Isabel; Mendo Lázaro, Santiago; León Del Barco, Benito; Felipe Castaño, Elena

    2017-09-29

    The vast majority of young people have mobile phones. This has become a must-have item in their lives, with traditional socialization spaces displaced by virtual ones. They use their mobile phones for many hours a day, to the detriment of their psychological and social functioning, showing greater vulnerability to abusive or excessive use, and more likely to become problematic or addicted users. This paper aims to study the impact of mobile phone abuse in a sample of college students, assessing the social, personal, and communicational realms and deepening understanding of the different cyberbullying profiles, analyzing who has more personal and social problems using mobiles: victims or aggressors. Whether the number of hours of mobile phone use has an effect on these problems will also be explored. The sample (1,200 students) was selected by multistage cluster sampling among the faculties of the University of Extremadura. Data were obtained through Victimization (CYB-VIC) and Aggression (CYB-AGRES) through the mobile phone scales, and the Questionnaire of Experiences related to Mobile (CERM). The results show that mobile phone abuse generates conflicts in young people of both sexes, although girls have more communication and emotional problems than boys. In addition, age, field of knowledge, victim/aggressor profile, and hours of mobile phone use are crucial variables in the communication and emotional conflicts arising from the misuse of mobile.

  4. A 2009 Mobile Source Carbon Dioxide Emissions Inventory for the University of Central Florida.

    Clifford, Johanna M; Cooper, C David

    2012-09-01

    A mobile source carbon dioxide (CO2) emissions inventory for the University of Central Florida (UCF) has been completed. Fora large urban university, more than 50% of the CO2 emissions can come from mobile sources, and the vast majority of mobile source emissions come from on-road sources: personal vehicles and campus shuttles carrying students, faculty, staff and administrators to and from the university as well as on university business trips. In addition to emissions from on-road vehicles, emissions from airplane-based business travel are significant, along with emissions from nonroad equipment such as lawnmowers, leaf blowers, and small maintenance vehicles utilized on campus. UCF has recently become one of the largest universities in the nation (with over 58,000 students enrolled in the fall 2011 semester) and emits a substantial amount of CO2 in the Central Florida area. For this inventory, students, faculty, staff and administrators were first surveyed to determine their commuting distances and frequencies. Information was also gathered on vehicle type and age distribution of the personal vehicles of students, faculty, administrators, and staff as well as their bus, car-pool, and alternate transportation usage. The latest US. Environmental Protection Agency (EPA)-approved mobile source emissions model, Motor Vehicle Emissions Simulator (MOVES2010a), was used to calculate the emissions from on-road vehicles, and UCF fleet gasoline consumption records were used to calculate the emissions from nonroad equipment and from on-campus UCF fleet vehicles. The results of this UCF mobile source emissions inventory were compared with those for another large U.S. university. With the growing awareness of global climate change, a number of colleges/universities and other organizations are completing greenhouse gas emission inventories. Assumptions often are made in order to calculate mobile source emissions, but without field data or valid reasoning, the accuracy of those

  13. Competitive Strategies and Improved Performance of Selected Nigeria Telecommunication Companies

    Waidi Adeniyi Akingbad

    2014-01-01

    Full Text Available Abstract The influence of globalization in telecommunication companies has greatly increased the level of competition in the industry and they are forced to be competitive to survive. Different types of strategies are put in place in order to be profitable and competitive. All these strategies are directed to attract, retain and maintain customers for continuous profitability. However, majority of them hardly measure the impact of their strategic innovation on their customers. The paper seeks to explore the influence of competitive strategies embarked upon by selected telecommunication companies in Nigeria on their performance. The paper also examines how competitive strategies could be implemented for improved customer satisfaction, retention and loyalty. Three null hypotheses were postulated to test the relationship between lower prices and customer satisfaction, uninterrupted trunk services and customer loyalty, and customer complaint handling and retention. Only customers using telephone service were selected as respondents from Lagos State. The state was stratified in to 20 local government council area and questionnaires were distributed to 125 respondents in each of them. The completion rate of the questionnaire in each of them is between 103 and 110. Survey research design was adopted to carry out the study. A structured questionnaire was designed and validated through the construct validity and tested for confirmation using the KMO measure of sampling adequacy. It was also made reliable using Cronbach’s Alpha test. From the study, findings revealed relationship between competitive strategies and customer satisfaction, retention and loyalty. The findings revealed that there is a relationship between competitive strategies, its constituents and performance of telecommunication companies. It is recommended that universal mobile telecommunication services (UMTS operators should adopt the culture of competitive strategies since it can

  14. Greening academia: Use and disposal of mobile phones among university students

    Ongondo, F.O.; Williams, I.D.

    2011-01-01

    Research highlights: → Students use/disposal of mobile phones was assessed via a large-scale survey and a takeback trial. → We estimate 3.7 m phones stockpiled by UK students; 29.3 and 28.1 m stockpiled for Europe and USA. → Many students replace phones at least once a year; only a small number have used a takeback service. → Monetary incentives have greatest influence over willingness to utilise takeback services. → Universities should partner with established operators to conduct targeted takeback services. - Abstract: Mobile phones have relatively short lifecycles and are rapidly seen as obsolete by many users within little over a year. However, the reusability of these devices as well as their material composition means that in terms of mass and volume, mobile phones represent the most valuable electronic products that are currently found in large numbers in waste streams. End-of-life mobile phones are a high value (from a reuse and resource perspective), high volume (quantity), low cost (residual monetary value) and transient (short lifecycle) electronic product. There are very large numbers of higher education (mainly university) students in the world - there are >2.4 million in the UK alone, 19 million in Europe and 18.2 million in the USA - and they often replace their mobile phones several times before graduation. Thus, because of the potentially significant environmental and economic impacts, a large scale survey of students at 5 UK universities was conducted to assess the behaviour of students with regard to their use and disposal of mobile phones. Additionally, a small scale trial mobile phone takeback service at one of the universities was carried out. The findings indicate that many students replace their phones at least once a year; replacing broken phones, getting upgrades from network operators, remaining 'fashionable' and a desire to have a handset with a longer battery life are the main reasons for such rapid replacement. Almost 60% of

    2007-08-01

    Full Text Available Little is known about companies whose core business is selling telecommunications products that lever open source projects. Open source telecommunications (OST companies operate in markets that are very different from typical software product markets. The telecommunications market is regulated, vertically integrated, and proprietary designs and special chips are widely used. For a telecommunications product to be useful, it must interact with both access network products and core network products. Due to specifications in Service Agreements Levels, penalties for failures of telecommunications products are very high. This article shares information that is not widely known, including a list of OST companies and the open source projects on which they depend, the size and diversity of venture capital investment in OST companies, the nature of the commercial product-open source software and company-project relationships, ways in which OST companies make money, benefits and risks of OST companies, and competition between OST companies. Analysis of this information provides insights into the ways in which companies can build business models around open source software. These findings will be of interest to entrepreneurs, top management teams of incumbent companies that sell telecommunications products, and those who care about Ontario's ability to compete globally.

  7. Greening academia: use and disposal of mobile phones among university students.

    Ongondo, F O; Williams, I D

    2011-07-01

    Mobile phones have relatively short lifecycles and are rapidly seen as obsolete by many users within little over a year. However, the reusability of these devices as well as their material composition means that in terms of mass and volume, mobile phones represent the most valuable electronic products that are currently found in large numbers in waste streams. End-of-life mobile phones are a high value (from a reuse and resource perspective), high volume (quantity), low cost (residual monetary value) and transient (short lifecycle) electronic product. There are very large numbers of higher education (mainly university) students in the world--there are>2.4 million in the UK alone, 19 million in Europe and 18.2 million in the USA--and they often replace their mobile phones several times before graduation. Thus, because of the potentially significant environmental and economic impacts, a large scale survey of students at 5 UK universities was conducted to assess the behaviour of students with regard to their use and disposal of mobile phones. Additionally, a small scale trial mobile phone takeback service at one of the universities was carried out. The findings indicate that many students replace their phones at least once a year; replacing broken phones, getting upgrades from network operators, remaining "fashionable" and a desire to have a handset with a longer battery life are the main reasons for such rapid replacement. Almost 60% of replaced phones are not sent to reuse or recycling operations but are stockpiled by students mainly as spare/backup phones. Approximately 61% of students own an extra mobile phone with male students replacing their phones more often than females. In particular, the results highlight the potentially huge stockpile of mobile phones--and consequently valuable supplies of rare metals--being held by the public; we estimate that there are 3.7 million phones stockpiled by students in UK higher education alone (29.3 and 28.1 million

    Objectives : There is insufficient evidence regarding the potential risk of mobile phone use on mental health. Therefore, the aim of this research was to examine the relationship between mobile phone use and mental health by measuring the levels of depression, anxiety, and stress among university students in Serbia and Italy. Methods : This cross-sectional study was carried out at two distinguished universities in Serbia and Italy from March to May of the 2015/2016 academic year and included 785 students of both genders. The questionnaire was compiled and developed from different published sources regarding the manner and intensity of mobile phone use, along with the Depression Anxiety Stress Scale (DASS 42) for measuring psychological health. The statistical analysis of the data included the application of binary logistic regression and correlation tests. Results: Statistical analysis indicates that anxiety symptoms are somewhat more present in younger students (odds ratio (OR) = 0.86, 95% confidence interval (CI): 0.76-0.96), in those who send more text messages SMSs (OR = 1.15, 95% CI: 1.11-1.31), and in those who browse the internet less frequently (OR = 0.84, 95% CI: 0.73-0.95). Stress is more common in students who make fewer calls a day (OR = 0.79, 95% CI: 0.64-0.97), as well in those who spend more time talking on the mobile phone per day (OR = 1.28, 95% CI: 1.12-1.56). The strongest predictor of high stress levels was keeping the mobile phone less than 1 m away during sleeping (OR = 1.48, 95% CI: 1.12-2.08). Conclusions: The results indicated that the intensity and modality of mobile phone use could be a factor that can influence causal pathways leading to mental health problems in the university student population.

    The risk of cell phone addiction is a social and psychological problem which has been proposed by psychologists, psychiatrists, and educational supervisors. The present study aimed to investigate the behavior of mobile phone addicts and mental health of university students of Shahrekord, Iran. This study was an applied research survey for the purposes of this study. The study population ýconsisted of all the students of Payame Noor University, Islamic Azad University, and University of Medical Sciences. The study population consisted of 296 students who were randomly selected from the target population. To collect data, two types of questionnaires were used, the Symptom Checklist-90-R(SCL-90-R) questionnaire, and the 32-point scale questionnaire of behavior associated with ýmobile phone use (Hooper and Zhou, 2007). Data analysis was performed using SPSS software, statistical analysis, frequency distribution, mean, one-way ANOVA, chi-square, and LSD (Least significance difference). The results showed that university students of Shahrekord, based on the six categories of mobile ýaddiction behaviors, were mostly placed in habitual behaviors (21.49%), addiction (21.49%), and intentional (21.49%) categories. By reviewing mental health indicators, it was found that students were affected with depressive disorder (17.30%), obsessive compulsive disorder (14.20%), and interpersonal sensitivity (13.80%). The results showed that there was a significant inverse relationship ýbetween mental health and habitual behaviors (r = -0.417), dependence (r = -0.317), addiction (r = -0.330), and incontinence (r = -0.309) in using mobile phone (P phone addiction reduced.

  15. "It's been a long journey": Exploring educationally mobile students' transition into STEM majors at a university

    Arreygue, Aimee

    Today, one third of all college students are considered educationally "mobile," which means they will change institutions during their undergraduate careers. The concept of educational mobility challenges the traditional idea of students moving through an educational pipeline in a linear fashion, and recognizes that many of today's students, including those in STEM fields (Science, Technology, Engineering, Mathematics), will have multiple transition points. The purpose of this qualitative study was to examine the transitional experiences of educationally mobile students moving into and through the STEM disciplines at a public university. Students who move from one educational environment to another undergo a significant transition process, and understanding this process for individual students and the institution's role in supporting transition has implications for educational policy. Grounded in the conceptual framework guided by Schlossberg's Transition Theory, and Swail, Redd, and Perna's Geometric Model for Student Persistence and Achievement, this study explores the following research question: How do students who are educationally mobile experience academic, social, and institutional support while transitioning into and through STEM disciplines at a four-year public university? Eighteen science and mathematics majors participated in this study, all of whom attended at least one institution of higher education prior to their current attendance at Mountain View University, a four-year comprehensive Hispanic Serving Institution (HSI) in Southern California. Participants were interviewed utilizing a semi-structured interview protocol and completed a demographic questionnaire as well. Trustworthiness measures included member checking and peer debriefing. The findings of this study show that educationally mobile students are savvy agents of their education, and make personal and professional sacrifices in their pursuit of a STEM degree. They want to connect to like

    Full Text Available This study was carried out in order to investigate whether mobile learning using Short Message Service (SMS was a method of learning adopted by the students enrolled in the School of Distance Education, Universiti Sains Malaysia. As adult learners who are in vocation, time and isolation are the bane of self-study. Since all the students own a mobile device that can receive SMS, educational messages can be sent directly to their devices. This experimental study explored the impact of learner’s characteristic, learning design and learning environment to their adoptability. This study utilised two models of data analysis, the Statistical Package for Social Science (SPSS Version 12.0 and the Rasch model analysis for measurement. The analysis was conducted on a sample of 105 students based on gender, age, ethnicity, programme of study and mobile device ownership. The students were from four different courses which are Bachelors of Science, Bachelor of Arts, Bachelor of Social Science and Bachelor of Management. The questionnaire-answer session were administered by the respective course managers in their tutorial sessions during the annual residential intensive course in the main campus of the Universiti Sains Malaysia. The result indicated that mobile learning has helped them to pace their studies. By using mobile learning, learners easily get any information that they need at anytime anywhere. Learners would also like to take another mobile learning assisted course if the courses are relevant to their learning needs. Furthermore, the SMS educational content received through their hand phone are easily remembered.

    Williams Nwagwu

    2011-12-01

    Full Text Available This paper deployed Roger’s innovation adoption theory to explain the penetration of mobile technology in Nigeria’s premier higher educational institution, the University of Ibadan, using data collected from 370 students. Technological characteristics such as relative advantage, complexity, trialability and compatibility explained adoption. Age is negatively and significantly related to adoption, and enrollees for the PhD. programme appear to be less intensive adopters of mobile phones than those in the master’s and bachelor’s degree programmes. Except for interpersonal relationship, all psychological variables, perceived popularity, perceived need and mass media use have a significant relationship with adoption of the technology. This study is limited to respondents selected from one university using a questionnaire. Apart from providing policy information to the university which is currently implementing mobile learning systems, the results of the study may provide useful information to telecom companies on how to target student communities in designing and packaging their products and services.

    1989-05-01

    The Office of Civilian Radioactive Waste Management (OCRWM) must, among other things, be equipped to readily produce, file, store, access, retrieve, and transfer a wide variety of technical and institutional data and information. The data and information regularly produced by members of the OCRWM Program supports, and will continue to support, a wide range of program activities. Some of the more important of these information communication-related activities include: supporting the preparation, submittal, and review of a license application to the Nuclear Regulatory Commission (NRC) to authorize the construction of a geologic repository; responding to requests for information from parties affected by and/or interested in the program; and providing evidence of compliance with all relevant Federal, State, local, and Indian Tribe regulations, statutes, and/or treaties. The OCRWM Telecommunications Network Plan (TNP) is intended to identify, as well as to present the current strategy for satisfying, the telecommunications requirements of the civilian radioactive waste management program. The TNP will set forth the plan for integrating OCRWM's information resources among major program sites. Specifically, this plan will introduce a telecommunications network designed to establish communication linkages across the program's Washington, DC; Chicago, Illinois; and Las Vegas, Nevada, sites. The linkages across these and associated sites will comprise Phase I of the proposed OCRWM telecommunications network. The second phase will focus on the modification and expansion of the Phase I network to fully accommodate access to the OCRWM Licensing Support System (LSS). The primary components of the proposed OCRWM telecommunications network include local area networks; extended local area networks; and remote extended (wide) area networks. 10 refs., 6 figs

    From May 2014 to February 2015, 319 university students (male, n=173; female n=146) of 18 to 24 years of age who carried mobile phones or computer tablets were selected as subjects. Staphylococcus spp. were detected in 101 of 319 samples (31.7%). In the present study, 11 strains of S. aureus were isolated and identified, not all of which were methicillin-resistant Staphylococcus aureus (MRSA). Overall, 14 species were identified, with 11 strains (10.9%) of S. xylosus being isolated at the highest frequency. Following this were eight strains (7.9%) of S. cohnii and seven strains (6.9%) each of S. capitis and S. haemolyticus. Staphylococcus spp. isolation was performed with bacterial samples obtained from the mobile phones of 22 specific subjects (males, n=12; females, n=10). Staphylococcus spp. isolation was performed on days -1, 7 and 30 of the experiment. Staphylococcus spp. were positively detected one or more times in 12 subjects (54.5%). In one subject (8.3%), all three tests were positive. Furthermore, two tests were positive in three (25.0%). In the eight remaining subjects (66.7%) Staphylococcus spp. were detected only once. For the three abovementioned tests, we investigated the pulsed-field gel electrophoresis (PFGE) patterns of the strains derived from the mobile phone and from the fingers of three subjects in whom the same bacterial species were isolated twice. From the cases with similarities between strains derived from the fingers and the mobile phones and cases, with consistency in the strains derived from the mobile phone at different times, commonality was observed in the strains derived from the fingers and mobile phones along with chronological uniformity in the strains derived from the mobile phones. A total of 101 Staphylococcus spp. strains were isolated from mobile phones. According to drug susceptibility tests, 99 strains (98.0%) were found to have some degree of resistance to drugs (excluding one strain each of S. aureus and S. haemolyticus

  13. Mobility in the academic careers at the Flemish universities: Results from the Human Resources in Research database

    Debacker, N.; Vandevelde, K.

    2016-07-01

    Worldwide mobility of researchers is generally correlated with an enhancement of the continuous interchange of ideas and is therefore highly stimulated. Flemish universities have occasionally been criticized for providing limited career opportunities for foreign researchers. However, presently no reliable data is available on researchers’ mobility in Flanders. For the five Flemish universities a full dataset is available at the ECOOM Centre for R&D Monitoring, containing all academic appointments and PhD’s awarded since 1990-1991. This dataset allows for prospective analyses within the Flemish university system as well as retrospective analyses and provides information on international and interuniversity recruitment and academic inbreeding. The present results confirm that the academic system in Flanders is indeed recognized by a tradition of internal recruitment. However specific differences between the universities and the scientific disciplines are observed calling for a more complex study of researchers’ mobility and of the relationship between mobility and research excellence.

  17. A Universal Communication Framework and Navigation Control Software for Mobile Prototyping Platforms

    Andreas Mitschele-Thiel

    2010-09-01

    Full Text Available In our contribution we would like to describe two new aspects of our low-cost mobile prototyping platform concept: a new hardware communication framework as well as new software features for navigation and control of our mobile platform. The paper is an extension of the ideas proposed in REV2009 [1] and is based on the therein used hardware platform and the monitoring and management software. This platform is based on the Quadrocopter concept – autonomous flying helicopter-style robots – and includes additional off-the-shelf parts. This leads to a universal mobile prototyping platform for communication tasks providing both mobile phone and WiFi access. However, the platform can provide these functions far more quickly than a technician on the ground might be able to. We will show that with our concept we can easily adapt the platform to the individual needs of the user, which leads to a very flexible and semi-autonomous system.

    Full Text Available Indirect method for soil loss predictions are plentiful, one of which is Universal soil-loss equation (USLE model. Available technology in mobile applications prompted the authors to develop a tool for calculating soil loss for many land types by transforming the USLE model into smart mobile application. The application is designed by using simple language for calculating each and every factor and lastly summing up the results. Factors that are involved in the calculation of soil loss are namely erosivity, erodibility, slope steepness, length of slope, land cover and conservation measures. The program will also be able to give its judgment for each of the prediction of soil loss rates for each and every possible land uses ranging from very light to very heavy. The application is believed to be useful for land users, students, farmers, planners, companies and government officers. It is shown by conducting usability testing using usability model, which is designed for mobile application. The results showed from 120 respondents that the usability of the system in this study was in “very good” classification, for three characteristics (ease of use, user satisfaction, and learnability.

    1986-01-01

    After years of waiting for Picture Archiving and Communication Systems (PACS) to become technologically mature and readily available at competitive costs, it appears that the ingredients are now available for producing at least the telecommunication component of the PACS. They are as follows: 1. A variety of pathways now exist for long-distance high-speed digital data transmission at acceptable costs. 2. Developments in computer technology and keen competition in the microcomputer and video display markets have markedly reduced to costs for components of digital data terminals. 3. The volume of native digitally acquired images is expanding yearly, whereas at the same time the pressure for converting images acquired in analog format to digital format is increasing. 4. The advantages of and potential for processing and storing imaging data in digital format are becoming more widely recognized. These factors, individually and collectively, favor the successful applications of image telecommunication to the field of diagnostic imaging. The authors have attempted to provide an overview of the subject and the basics of this emerging technology

  20. Mobile devices and augmented reality in the learning process of university students

    Julio Cabero Alemanra

    2017-03-01

    Full Text Available Augmented Reality is an emerging technology having more and more influence on teaching. Together with it, mobile technology is drawn as one of the most effective pairing to support a meaningful and omnipresent learning. However, for it to be able to work with validity, the student must be motivated to use them during the training process, so that the learning process can work with validity. By means of the application of the Instructional Material Motivational Survey by Keller (1983, we have tried to determine the degree of motivation that students, from the Degree of Pedagogy at Seville University (N=148, have about the usage in the  classroom of notes enriched through Augmented Reality and available in mobile devices. Through an application designed exclusively for the subject, it has been valued in a positive way by the students who participate in this research. Moreover, we can highlight that the main finding achieved has been the narrow relationship between the students' motivation to use the enriched notes and the degree of success in the subject when using them. Likewise, we can confirm that Augmented Reality benefits the learning process. Therefore, we conclude the validity and viability of such a paring related to the achievement of an improvement in the students' learning results.

  1. A Tale of Many Cities: Universal Patterns in Human Urban Mobility

    Noulas, Anastasios; Scellato, Salvatore; Lambiotte, Renaud; Pontil, Massimiliano; Mascolo, Cecilia

    2012-01-01

    The advent of geographic online social networks such as Foursquare, where users voluntarily signal their current location, opens the door to powerful studies on human movement. In particular the fine granularity of the location data, with GPS accuracy down to 10 meters, and the worldwide scale of Foursquare adoption are unprecedented. In this paper we study urban mobility patterns of people in several metropolitan cities around the globe by analyzing a large set of Foursquare users. Surprisingly, while there are variations in human movement in different cities, our analysis shows that those are predominantly due to different distributions of places across different urban environments. Moreover, a universal law for human mobility is identified, which isolates as a key component the rank-distance, factoring in the number of places between origin and destination, rather than pure physical distance, as considered in some previous works. Building on our findings, we also show how a rank-based movement model accurately captures real human movements in different cities. PMID:22666339

  4. Enabling Mobile Communications for the Needy: Affordability Methodology, and Approaches to Requalify Universal Service Measures

    Louis-Francois PAU

    2009-01-01

    Full Text Available This paper links communications and media usage to social and household economics boundaries. It highlights that in present day society, communications and media are a necessity, but not always affordable, and that they furthermore open up for addictive behaviors which raise additional financial and social risks. A simple and efficient methodology compatible with state-of-the-art social and communications business statistics is developed, which produces the residual communications and media affordability budget and ultimately the value-at-risk in terms of usage and tariffs. Sensitivity analysis provides precious information on bottom-up communications and media adoption on the basis of affordability. This approach differs from the regulated but often ineffective Universal service obligation, which instead of catering for individual needs mostly addresses macro-measures helping geographical access coverage (e.g. in rural areas. It is proposed to requalify the Universal service obligations on operators into concrete measures, allowing, with unchanged funding, the needy to adopt mobile services based on their affordability constraints by bridging the gap to a standard tariff. Case data are surveyed from various countries. ICT policy recommendations are made to support widespread and socially responsible communications access.

  17. The Use of a Mobile Learning Management System at an Online University and Its Effect on Learning Satisfaction and Achievement

    Won Sug Shin

    2015-06-01

    Full Text Available This study investigates online students’ acceptance of mobile learning and its influence on learning achievement using an information system success and extended technology acceptance model (TAM. Structural equation modeling was used to test the structure of individual, social, and systemic factors influencing mobile learning’s acceptance, and how said acceptance influences learning satisfaction and achievement. Unlike earlier TAM-related research that did not provide a broad view of technological acceptance and its impact on learning activities, the present study’s results highlight the relationship between behavioral intention/learning satisfaction and learning achievement. Additionally, this study tests the theoretical model of successful mobile learning by empirically accepting mobile learning management systems. The findings further imply that students at online universities have started to accept mobile technology as a new learning tool; consequently, its acceptance has influenced their learning achievement both directly and indirectly. These discoveries should facilitate a better understanding of students’ usage of mobile learning systems in higher education, and provide timely guidance for its development and implementation.

  18. Mobile phone use while driving in a sample of Spanish university workers.

    Gras, M Eugenia; Cunill, Monica; Sullman, Mark J M; Planes, Montserrat; Aymerich, Maria; Font-Mayolas, Silvia

    2007-03-01

    A number of epidemiological studies have reported drivers who use a mobile phone while driving have an elevated risk of being involved in a crash. This is particularly concerning as a survey of drivers in the Spanish region of Catalunya found that approximately 87% own mobile phones. The present study investigated the reported frequency of mobile phone use on Spanish roads (for talking and using SMS), the characteristics of the drivers who use mobile phones while driving and whether they altered their driving behaviour when using a mobile phone. The research found that more than 60% use a mobile phone while driving and that the phone is mostly used for making calls, rather than using SMS. In general, males and females use mobile phones about the same reported frequency, although males were more likely to use a mobile phone to talk on the highway. The pattern for age was the same for both male and female participants, with the younger drivers using SMS more frequently than older drivers. On urban roads almost half of the drivers reported changing their driving behaviour when using a mobile phone, while on the highway this figure was slightly over 41%. The reported frequency of using a mobile phone to talk on urban roads was significantly correlated with crash involvement. However, this affect disappeared once the contributions of the demographic and descriptive variables had been partialled out.

  7. Studying the effects of mobile phone waves on electro cardiogram parameters of students in zahedan university of medical sciences.

    Komeili, Gholamreza; Nabizadeh Sarabandi, Sima

    2012-01-01

    The increasing use of mobile phones in recent years has caused concerns about the effects of electromagnetic waves of mobile phonesonhuman biological processes. This study was conducted in order to survey the effects of mobile electromagnetic waves on electro cardiogram parameters as heart rate, TP segment, PR interval, Time of QRS and T waves, and voltage of R wave. In this quasi experimental study, 40 students, of Zahedan medical science University, 20 boys and 20 girls, who had referred to the laboratory of physiology were selected. At first a normal electro cardiogram in lead I was recorded for each of the subjects for 20 seconds. Then a mobile phone was placed near their body and while mobile was ringing and talking two other electrocardiograms were recording for 20 seconds. Electro cardiograms were recorded with power lab device and analyzed by chart 5 software. Finally an ANOVA was employed to analyze the data through the SPSS 17, followed by a Tukey test. There was significant difference between heart rate during talking in comparison with heart rate during ringing and resting in both genders. There was a significant decrease of resting TP segment in comparison with TP segment during ringing and talking in males whereas in females TP segment indicated significant difference in all three conditions. There was a significant increase in T wave time in males during talking in comparison with resting and ringing; however there was no significant difference in that of females in any of the three stated conditions. This study revealed that there is not any significant difference in PR interval, Time of QRS wave and R wave voltage. According to the results of this study, mobile phones can affect the heart rate, TP segment and time of T wave. Therefore, it seems that long term use can affect heart. Based on several reports on the effects of these waves on biological processes, precautionary measures should be taken about using mobile phones.

    2001-12-01

    Full Text Available The opening of the telecommunications market is acceleration due to the world trends of deregulation and privatization under the WTO basic telecommunications agreements. Diversification of services and fast and efficient equipment procurement are becoming necessary conditions for the survival of telecommunications operators. However, the issue here is that telecommunications operators are still bound by the GPA (Government Procurement Agreement based on conditions of monopoly even though the procurement market in Korean is open substantially since 1997. Under such conditions, the continued application of the GPA on telecommunications operator who is highly competitive may result in a negative impact on the telecommunications business and quality of telecommunications service by undermining the autonomy of operator and decreasing operator’s procurement competitiveness. Therefore, this study examines the GPA and the issues raised by the agreement, and also attempts to suggest revisions or means of abrogating the unfair GPA with regards to the development and deregulation of the telecommunications business.

    Eugenia Minasidou

    2015-12-01

    Full Text Available Introduction: Mobile phone use can be addictive for the young. However, little is known about the behavioral and biological effects of this addiction among the student population. Aim: The purpose of this study was to explore the effects of mobile phone use on the health behaviors and specific biomarkers in a sample of Greek students. Methods: Sample included 104 Nursing students from a stratified randomised sample. In 30 ran- domly selected out of the 104 students, melatonin and total antioxidant levels in saliva were also measured. Mobile phone dependence was estimated with the Mobile Phone Dependence Question- naire by Toda et al and general health with the GHQ-28. We used the Antioxidant assay kit-SIGMA to measure the total antioxidant levels and the anosoenzymic method ELISA (IBL kit to measure melatonine levels. Analysis was performed with SPSS v15.0 software. All hypothesis were tested at a p<0,05 level. Results: No statistical difference between genders was detected (p=0.182. High dependence was apparent in 13.5% of the sample, which correlated with worse general health (p=0.004, greater alcohol consumption (p=0.007, sleep disturbances (p=0.02 and worse nutritional habits (p=0.032. Moreover, high mobile dependent students exhibited higher concentration of early morning mel- atonin (p=0.07 and lower antioxidant concentration (p=0.333 in saliva, compared to low mobile dependent students. Conclusions: Excessive use of mobiles among students seems to correlate with unhealthy habits and impaired health. The effect in well known biomarkers may suggest the burden of the health of the student population. However, the long term effects on health require further investigation.

  13. Mobile technologies: expectancy, usage, and acceptance of clinical staff and patients at a university medical center.

    Illiger, Kristin; Hupka, Markus; von Jan, Ute; Wichelhaus, Daniel; Albrecht, Urs-Vito

    2014-10-21

    Despite their increasing popularity, little is known about how users perceive mobile devices such as smartphones and tablet PCs in medical contexts. Available studies are often restricted to evaluating the success of specific interventions and do not adequately cover the users' basic attitudes, for example, their expectations or concerns toward using mobile devices in medical settings. The objective of the study was to obtain a comprehensive picture, both from the perspective of the patients, as well as the doctors, regarding the use and acceptance of mobile devices within medical contexts in general well as the perceived challenges when introducing the technology. Doctors working at Hannover Medical School (206/1151, response 17.90%), as well as patients being admitted to this facility (213/279, utilization 76.3%) were surveyed about their acceptance and use of mobile devices in medical settings. Regarding demographics, both samples were representative of the respective study population. GNU R (version 3.1.1) was used for statistical testing. Fisher's exact test, two-sided, alpha=.05 with Monte Carlo approximation, 2000 replicates, was applied to determine dependencies between two variables. The majority of participants already own mobile devices (doctors, 168/206, 81.6%; patients, 110/213, 51.6%). For doctors, use in a professional context does not depend on age (P=.66), professional experience (P=.80), or function (P=.34); gender was a factor (P=.009), and use was more common among male (61/135, 45.2%) than female doctors (17/67, 25%). A correlation between use of mobile devices and age (P=.001) as well as education (P=.002) was seen for patients. Minor differences regarding how mobile devices are perceived in sensitive medical contexts mostly relate to data security, patients are more critical of the devices being used for storing and processing patient data; every fifth patient opposed this, but nevertheless, 4.8% of doctors (10/206) use their devices for this

  19. Admission Systems and Student Mobility: A Proposal for an EU-Wide Registry for University Admission

    Cecile Hoareau McGrath

    2016-07-01

    Full Text Available Europe’s higher education systems are struggling to respond to the established mass demand for higher education, especially given the proportional decline in available resources per student and, more generally the demand for an ever longer education and reduction of the population of working age due to demographic decline. In addition, growing student mobility puts pressure on admission systems to set up relevant procedures for applicants who wish to enter a country. Admission systems to higher education constitute one key element in the mitigation of these challenges. Admissions can regulate student flows, and play a key role in guaranteeing the acquisition of skills in higher education by matching student profiles to their desired courses of study. This article puts European admission systems in perspective. The issue of regulation of student mobility is topical, given the broader and salient discussion on migration flows in Europe. The article uses international comparisons with systems such as the US, Australia and Japan, to provide a critical overview of the role of admission systems in an often overlooked but yet fundamental part of the European Higher Education Area, namely student mobility. The paper also argues for the creation of an information-sharing EU registry on admissions practices for mobile students.

  1. Usability Testing of a Collaborative and Interactive University on a Mobile Device

    Gavin McArdle

    2009-10-01

    Full Text Available Abstract - The use of mobile devices for delivering learning tools is an attractive concept. Termed mobile learning (m-learning, this new technology allows people to participate in learning activities without being tied to a fixed location and provides users with convenient and flexible access to learning resources anytime and anywhere. While many m-learning applications have been developed to date, most provide tools to help students’ with specific learning tasks rather than a general interface to online courses. Few sup-port online learning communities or allow users to download multimedia learning content. These features would engage mobile users and enable them to interact with one another, thus allowing them to participate in group learning activities despite their changing location. In this article, we describe an m-learning system which we have developed which aims to incorporate these facilities. This system provides access to multimedia learning resources and supports mobile users in an interactive synchronous learning environment with their desktop peers. Details of the evaluation techniques which we utilised to appraise the system are provided and the results are presented. Feedback suggests that the features offered by our system are beneficial for collaborative m-learning.

    Nemiroski, Alex; Christodouleas, Dionysios C; Hennek, Jonathan W; Kumar, Ashok A; Maxwell, E Jane; Fernández-Abedul, Maria Teresa; Whitesides, George M

    2014-08-19

    This paper describes an inexpensive, handheld device that couples the most common forms of electrochemical analysis directly to "the cloud" using any mobile phone, for use in resource-limited settings. The device is designed to operate with a wide range of electrode formats, performs on-board mixing of samples by vibration, and transmits data over voice using audio--an approach that guarantees broad compatibility with any available mobile phone (from low-end phones to smartphones) or cellular network (second, third, and fourth generation). The electrochemical methods that we demonstrate enable quantitative, broadly applicable, and inexpensive sensing with flexibility based on a wide variety of important electroanalytical techniques (chronoamperometry, cyclic voltammetry, differential pulse voltammetry, square wave voltammetry, and potentiometry), each with different uses. Four applications demonstrate the analytical performance of the device: these involve the detection of (i) glucose in the blood for personal health, (ii) trace heavy metals (lead, cadmium, and zinc) in water for in-field environmental monitoring, (iii) sodium in urine for clinical analysis, and (iv) a malarial antigen (Plasmodium falciparum histidine-rich protein 2) for clinical research. The combination of these electrochemical capabilities in an affordable, handheld format that is compatible with any mobile phone or network worldwide guarantees that sophisticated diagnostic testing can be performed by users with a broad spectrum of needs, resources, and levels of technical expertise.

  5. The protection of the Cyrillic alphabet in telecommunications: Taxation aspects

    Marilović Đorđe

    2016-01-01

    Full Text Available The use of Cyrillic and other specific alphabets is discouraged in some telecommunication services. In this paper; the author focuses on unequal treatment of the Cyrillic alphabet in telecommunications (in SMS messages, which is incompatible with the interests of a multilingual society to cherish its linguistic heritage and diversity. Referring to the Convention on the Protection and Promotion of the Diversity of Cultural Expression (2005, the author suggests introducing measures which would lead to removing the discriminatory pricing of Cyrillic SMS messages; and introducing tax measures which would support mobile network operators and prevent possible market inequalities stemming from introducing these measures. The suggested solution is applicable to any multicultural society facing the same problem; regardless of languages in question.

    About 50% of university students overconsume alcohol, and drinking habits in later adulthood are to some extent established during higher educational studies. Several studies have demonstrated that Internet-based interventions have positive effects on drinking habits among university students. Our recent study evaluated two mobile phone apps targeting drinking choices at party occasions via personalized feedback on estimated blood alcohol concentration (eBAC) for students with hazardous drinking. No changes in drinking parameters were found over a seven-week period apart from an increase in number of drinking occasions among men for one of the apps tested. Up to 30% of the study participants drank at potentially harmful levels: higher than the national recommended number of standard drinks per week (a maximum of 9 for women and 14 for men) in Sweden. (1) To evaluate improved versions of the two mobile phone apps tested in our prior trial, in a new, 3-armed randomized controlled trial among university students with at least hazardous drinking habits according to the Alcohol Use Disorders Identifications Test (AUDIT; Study 1). (2) After 6 weeks, to target study participants showing alcohol consumption higher than the national recommended levels for standard drinks per week by offering them participation in a second, 2-armed randomized trial evaluating an additional mobile phone app with skill enhancement tasks (Study 2).

  10. Universal design and the challenge of diversity: reflections on the principles of UD, based on empirical research of people's mobility.

    Winance, Myriam

    2014-01-01

    The author analyses some theoretical presuppositions of the Universal Design approach. She shows that it is based on two paradoxes: (1) it reduces diversity to the "universal", (2) it depends on an asymmetrical view of abilities and disabilities. The author suggests a way of changing this concept in order to take into account uniqueness and diversity, in order to allow the shaping of abilities. The data are taken from an ethnographical survey carried out between 2007 and 2009 made up of in-depth interviews with wheelchair users and their families. The interviews were analysed inductively using the Nvivo© programme. The mobility of people in wheelchairs, and their capacity to act, are linked to their particular experience and are the result of a process of adjustment and arrangement. This process involves specific and varied resources and leads to changes in the individuals, in their dis/abilites, but also in their perceptions. This analysis leads to a change in the question of policy. This question is no longer "how to include diversity using the definition of 'universal'", but "how to bring out and articulate this diversity, so as to vary the qualities of persons and the world in which they live". Implications for Rehabilitation "Inaccessibility" is analysed in terms of a discrepancy between the user and her/his environment and in terms of experience. Accessibility is analysed as a process of adjustment and practical arrangements between the person and her/his environment. The universalism of Universal Design is criticized in the way it tries to force the variety of users into the uniqueness of one materiality. Emphasis is put on diversity and the necessity of articulating this diversity in a plural world offering various resources that individuals can call upon to act, depending on what they are and on what they want to become.

    2008-12-01

    Telemedicine is increasingly used to provide acute stroke expertise for hospitals without full-time neurological services. Teleconsulting through mobile laptop computers may offer more flexibility compared with hospital-based services, but concerns about quality and technical reliability remain. We conducted a controlled trial, allocating hospital-based or mobile teleconsulting in a shift-by-shift sequence and evaluating technical parameters, acceptability, and impact on immediate clinical decisions. Both types of telemedicine workstations were equipped with DICOM (Digital-Imaging-and-Communications-in-Medicine) viewer and videoconference software. The laptop connected by asymmetrical broadband UMTS (Universal-Mobile-Telecommunication-Systems) technology with a one-way spoke-to-hub video transmission, whereas the hospital-based device used landline symmetrical telecommunication, including a 2-way videoconference. One hundred twenty-seven hospital-based and 96 mobile teleconsultations were conducted within 2 months without any technical breakdown. The rates per allocated time were similar with 3.8 and 4.0 per day. No significant differences were found for durations of videoconference (mean: 11+/-3 versus 10+/-3 minutes, P=0.07), DICOM download (3+/-3 versus 4+/-3 minutes, P=0.19), and total duration of teleconsultations (44+/-19 versus 45+/-21 minutes, P=0.98). Technical quality of mobile teleconsultations was rated worse on both sides, but this did not affect the ability to make remote clinical decisions like initiating thrombolysis (17% versus 13% of all, P=0.32). Teleconsultation using a laptop workstation and broadband mobile telecommunication was technically stable and allowed remote clinical decision-making. There remain disadvantages regarding videoconference quality on the hub side and lack of video transmission to the spoke side.

  16. Measurement and analysis of electromagnetic pollution generated by GSM-900 mobile phone networks in Erciyes University, Turkey.

    Sorgucu, Ugur; Develi, Ibrahim

    2012-12-01

    Mobile phones are becoming increasingly important in our everyday lives. The rising number of mobile phones reflects a similar increase in the number of base stations. Because of this rapid evolution, the establishment and planning of new base stations has become mandatory. However, the rise in the number of base stations, in terms of human health, is potentially very harmful. It is important to analyze the radiation levels of base stations until we can confirm that they are definitely not harmful in the long term. Mapping of electromagnetic field (EMF) is also important from a medical point of view because it provides useful information, for example, on the detection of diseases caused by EMF. With the help of this information the distribution of diseases over different regions can be obtained. In this article, the electromagnetic radiation levels of base stations were measured at 80 different points in Erciyes University (ERU), Turkey and detailed information about the measurement tools and measurement method were given. It was observed that no area in ERU exceeded the national and international limits. It is also observed that the effects of base stations vary according to duration and degree of exposure. Therefore, if people are exposed to a very low-intensity electromagnetic field for a very long time, serious health problems can occur.

    The influence of temporal daily exposure to global system for mobile communications (GSM) and universal mobile telecommunications systems and high speed down-link packet access (UMTS-HSDPA) is investigated using spectrum analyser measurements in two countries, France and Belgium. Temporal variations and traffic distributions are investigated. Three different methods to estimate maximal electric-field exposure are compared. The maximal realistic (99 %) and the maximal theoretical extrapolation factor used to extrapolate the measured broadcast control channel (BCCH) for GSM and the common pilot channel (CPICH) for UMTS are presented and compared for the first time in the two countries. Similar conclusions are found in the two countries for both urban and rural areas: worst-case exposure assessment overestimates realistic maximal exposure up to 5.7 dB for the considered example. In France, the values are the highest, because of the higher population density. The results for the maximal realistic extrapolation factor at the weekdays are similar to those from weekend days.

    2014-07-02

    Brief interventions via the internet have been shown to reduce university students' alcohol intake. This study tested two smartphone applications (apps) targeting drinking choices on party occasions, with the goal of reducing problematic alcohol intake among Swedish university students. Students were recruited via e-mails sent to student union members at two universities. Those who gave informed consent, had a smartphone, and showed risky alcohol consumption according to the Alcohol Use Disorders Identification Test (AUDIT) were randomized into three groups. Group 1 had access to the Swedish government alcohol monopoly's app, Promillekoll, offering real-time estimated blood alcohol concentration (eBAC) calculation; Group 2 had access to a web-based app, PartyPlanner, developed by the research group, offering real-time eBAC calculation with planning and follow-up functions; and Group 3 participants were controls. Follow-up was conducted at 7 weeks. Among 28574 students offered participation, 4823 agreed to join; 415 were excluded due to incomplete data, and 1932 fulfilled eligibility criteria for randomization. Attrition was 22.7-39.3 percent, higher among heavier drinkers and highest in Group 2. Self-reported app use was higher in Group 1 (74%) compared to Group 2 (41%). Per-protocol analyses revealed only one significant time-by-group interaction, where Group 1 participants increased the frequency of their drinking occasions compared to controls (p = 0.001). Secondary analyses by gender showed a significant difference among men in Group 1 for frequency of drinking occasions per week (p = 0.001), but not among women. Among all participants, 29 percent showed high-risk drinking, over the recommended weekly drinking levels of 9 (women) and 14 (men) standard glasses. Smartphone apps can make brief interventions available to large numbers of university students. The apps studied using eBAC calculation did not, however, seem to affect alcohol consumption among

  3. Standby battery requirements for telecommunications power

    May, G.J. [The Focus Partnership, 126 Main Street, Swithland, Loughborough, Leics LE12 8TJ (United Kingdom)

    2006-08-25

    The requirements for standby power for telecommunications are changing as the network moves from conventional systems to Internet Protocol (IP) telephony. These new systems require higher power levels closer to the user but the level of availability and reliability cannot be compromised if the network is to provide service in the event of a failure of the public utility. Many parts of these new networks are ac rather than dc powered with UPS systems for back-up power. These generally have lower levels of reliability than dc systems and the network needs to be designed such that overall reliability is not reduced through appropriate levels of redundancy. Mobile networks have different power requirements. Where there is a high density of nodes, continuity of service can be reasonably assured with short autonomy times. Furthermore, there is generally no requirement that these networks are the provider of last resort and therefore, specifications for continuity of power are directed towards revenue protection and overall reliability targets. As a result of these changes, battery requirements for reserve power are evolving. Shorter autonomy times are specified for parts of the network although a large part will continue to need support for hours rather minutes. Operational temperatures are increasing and battery solutions that provide longer life in extreme conditions are becoming important. Different battery technologies will be discussed in the context of these requirements. Conventional large flooded lead/acid cells both with pasted and tubular plates are used in larger central office applications but the majority of requirements are met with valve-regulated lead/acid (VRLA) batteries. The different types of VRLA battery will be described and their suitability for various applications outlined. New developments in battery construction and battery materials have improved both performance and reliability in recent years. Alternative technologies are also being proposed

  12. The mobile application preferences of undergraduate university students: A longitudinal study

    Andrea Potgieter

    2015-09-01

    Objective: The research problem of this article is centred on the preferences for smartphone apps by the growing market of smartphone users in South Africa. The study includes a demographic profile of the users to establish what attracts this market into downloading smartphone apps. Methodology: The study employed a mono-method, quantitative methodological framework with an online survey as the data collection instrument. The survey was conducted amongst undergraduate university students in 2013 and repeated again in 2014. Results: It was found that the ‘young adult’ demographic, of which the sample of undergraduate university students formed a part, was discerning about which apps they downloaded and that the frequency of downloads occurred less than once a month in most cases. Information and entertainment needs were amongst the top reasons users indicated as motivations for downloading apps. Conclusion: The study’s findings confirmed that the sample had definite preferences regarding which apps the users were downloading, and these preferences depended on the needs that they wished to fulfil. The study also revealed that, even though users were aware of security threats associated with downloading apps, this knowledge did not deter them from continuing to download apps. Future research recommendations also arose from the study, giving direction to prospective studies.

    2015-01-01

    The aims of this study were to investigate the prevalence of neck pain among computer workers at Hail University, Saudi Arabia and to compare the cervical range of motion (ROM) of female computer workers suffering from neck pain to the cervical ROM of healthy female computer workers. One hundred and seventy-six female volunteers between 20 and 46 years of age were investigated. Fifty-six of these volunteers were staff members, 22 were administrators and 98 were students. The Cervical Range of Motion (CROM) instrument was used to measure the ROM of the cervical spine. A questionnaire was used to assess participants for the presence of neck pain. The data were analyzed using the Statistical Package for Social Sciences (SPSS) software, and the level of significant was set at p pain (75%) among computer workers at Hail University, particularly among students. There were significant differences in cervical lateral flexion, rotation to the right side and protraction range between the pain and pain-free groups. Our results demonstrated that cervical ROM measurements, particularly cervical lateral flexion, rotation and protraction, could be useful for predicting changes in head and neck posture after long-term computer work.

    Full Text Available Paper presents telecommunications security issues with dynamically changing networking. Paper also presents performance indicators of authentication as an integral part of the approach to non-public information. Expected level of security depend on relevant ITS services requirements, different solutions require different levels of quality. Data volumes transferred both in private data vehicle on board networks as well as between vehicles and infrastructure or other vehicles significantly and progressively grow. This trend leads to increase of the fatal problems if security of the wide area networks is not relevantly treated. Relevant communications security treatment becomes crucial part of the ITS telecommunications solution because probability of hazards appearances grow if vehicles networks are integrated in the dynamically organized wide area networks. Besides of available "off shelf" security tools solution based on non-public universal identifier with dynamical extension and data selection according to actor role or category is presented including performances indicators for the authentication process.

  3. Network externalities in telecommunication industry: An analysis of Serbian market

    Trifunović Dejan

    2016-01-01

    Full Text Available This paper deals with network competition and provides empirical analysis of market concentration, network and call externalities, access pricing, price discrimination and switching costs in Serbian mobile phone telecommunications market. It is shown that network externalities governed the expansion of this market until 2008. Upon entry of VIP incumbents didn't engage in predatory behaviour towards entrant aiming to benefit from locked- in users. The policy of mobile phone number portability reduced on-net prices and substantially increased consumer's surplus. In contrast to some previous research, this policy was pro-competitive in Serbia. We have also determined that users of the network with the largest market share benefit the most from call externalities. Finally, one network does not price discriminate between outgoing and incoming roaming calls, which implies that users of this network have higher level pecuniary externalities in roaming compared to users of price discriminating networks.

  4. [Analysis of behavior related to use of the Internet, mobile telephones, compulsive shopping and gambling among university students].

    Ruiz-Olivares, Rosario; Lucena, Valentina; Pino, M José; Herruzo, Javier

    2010-01-01

    The aim of this study is to obtain knowledge about habits related to addictive behaviour (pathological gambling, Internet, compulsive shopping, use of mobile telephones, etc.) that may be displayed by young students at the University of Cordoba (Spain), and to relate this behaviour with variables such as age, sex, course year, macro-field of study (arts/sciences) and the consumption of substances such as alcohol, tobacco, cannabis and cocaine. Using an ex-post facto single-group design (Montero & Leon, 2007), we applied a questionnaire especially designed to gather socio-demographic information on substance use and behavioural patterns related to "non-substance" addictions, which included the Shopping Addiction Test, Echeburua's Internet Addiction Test (2003) and Fernandez-Montalvo and Echeburua's Short Pathological Gambling Questionnaire (1997). A total of 1,011 students participated in the study (42.7% males and 57.3% females), with an age range of 18 to 29. Significant differences were found between mean score on the questionnaires and variables such as age, sex, field of studies and course year. It would seem that being female is a protective factor for Internet and gambling addiction, being a sciences student is a risk factor for gambling addiction, and being older and being an arts student are risk factors for shopping addiction. In conclusion, it can be stated that the students surveyed showed moderate incidence of behaviours such as Internet browsing, gambling, shopping and mobile phone use, whilst a very small group are close to having an addiction problem with such behaviours.

    question. The students must answer each question correctly in order to proceed to the next location and accrue points in the game and multiple attempts reduce the number of points earned when the correct answer is found. The questions are either multiple choice or involve touch-screen interaction to identify a specific geologic feature. Initial testing of the prototype game in Historical and Physical geology courses at Utah State University indicate that students enjoy the mobile "exploration" nature of the game as well as experiencing photographs of geologic features rather than traditional cartoons. Qualitative evaluation using anonymous surveys was conducted to help determine the usability of the game and the potential effectiveness of this technology-based approach. Students were asked about the degree of fun and difficulty of the game, content learned, and their overall response to features they liked/disliked about it. The results of these early assessments are positive, both in regard to the improvement of students' understanding of key geology concepts and their enjoyment of learning with the technology in a mobile orienteering manner. This is a positive first step in an innovative teaching tool with the power to overcome the pervasive problem of the boring first year STEM course and make world-class field trips accessible to all.

    Throughout its 30-year existence, ESA has played a key role by providing telecommunications infrastructures that have allowed the in-orbit validation, qualification and demonstration of equipment, technology and services. In the past, this has been achieved through the provision of dedicated satellites like OTS, Marecs, Olympus and Artemis, as well as by the implementation of piggy-back payloads on other ESA or commercial satellites. Today, due to the importance of satellite telecommunications, ESA continues to support this sector mainly through its ARTES - Advanced Research in Telecommunications - Programme.

  11. Evaluating managed care's special telecommunications needs.

    Harrison, P; Schenk, D

    1993-11-01

    Right now, managed care is a vast cosmic soup. But whether its ultimate form is the result of a bureaucratic big bang or a series of small industry explosions, one thing seems clear: telecommunications is the framework upon which managed care will be built. Managed care's primary players--purchasers, providers and payors--have already discovered the unifying power of telecommunications within their respective worlds. However, as the three worlds collide, an entirely new set of special telecommunications needs arises. And most of these needs can be distilled into three basic requirements: bigger networks, faster networks and smarter networks.

  12. Determinants of Customers` Churn Decision in the Nigeria Telecommunication Industry: An Analytic Hierarchy Process Approach

    2015-10-01

    Full Text Available This paper describes the application of Analytic Hierarchy Process (AHP for unraveling customers’ motivation for churn of telecommunication network in Nigeria. By identifying, modeling and measuring of customers` churn motivations across four mobile telecommunication service providers in Nigeria. AHP was used to design a hierarchical model of seven criteria for customers` churning of network and investigates the relative priorities of the criteria through a pairwise comparison. The questionnaire were administered through convenient sampling to 480 mobile telecommunication customers and was completed and returned by 438 mobile phone subscribers in Lagos state, Nigeria, but only 408 copies were useful for the analysis of this study. The result shows that six out of the seven criteria have weight above 10% in their individual contribution to motivating customer churn behavior in the Nigeria telecommunication industry. The inefficient data/ internet plan criterion has the highest weight of 18.81% relative to the churn decision. Thus, AHP effectively supported modeling and analyzing subscribers` motivation toward good marketing decision for both the individual and the organization. It helps in developing an analytic and intelligible framework of decision-making on complex problem of customer churn in an emerging market like Nigeria

  14. A universal self-charging system driven by random biomechanical energy for sustainable operation of mobile electronics

    Niu, Simiao; Wang, Xiaofeng; Yi, Fang; Zhou, Yu Sheng; Wang, Zhong Lin

    2015-12-01

    Human biomechanical energy is characterized by fluctuating amplitudes and variable low frequency, and an effective utilization of such energy cannot be achieved by classical energy-harvesting technologies. Here we report a high-efficient self-charging power system for sustainable operation of mobile electronics exploiting exclusively human biomechanical energy, which consists of a high-output triboelectric nanogenerator, a power management circuit to convert the random a.c. energy to d.c. electricity at 60% efficiency, and an energy storage device. With palm tapping as the only energy source, this power unit provides a continuous d.c. electricity of 1.044 mW (7.34 W m-3) in a regulated and managed manner. This self-charging unit can be universally applied as a standard `infinite-lifetime' power source for continuously driving numerous conventional electronics, such as thermometers, electrocardiograph system, pedometers, wearable watches, scientific calculators and wireless radio-frequency communication system, which indicates the immediate and broad applications in personal sensor systems and internet of things.

    2014-06-01

    [Purpose] The present study aimed to determine the effect of an 8-week program of joint mobilization on changes in pelvic obliquity and pain level in seventeen female university students aged in their 20's with sacroiliac joint dysfunction by dividing them into two groups: a joint mobilization group (MWM) and a control group. [Subjects] Seventeen subjects were selected from female university students aged in their 20's attending N University in Cheon-An City, Korea, The subjects had sacroiliac joint syndrome, but experienced no problems with daily living and had no previous experience of joint mobilization exercise. The subjects were randomly assigned to a joint mobilization group of eight and a control group of nine who performed joint mobilization exercise. [Methods] Body fat and lean body mass were measured using InBody 7.0 (Biospace, Korea). The Direct Segmental Multi-frequency Bioelectrical Impedance Analysis Method (DSM-BIA) was used for body composition measurement. A pressure footstool (Pedoscan, DIERS, Germany) and a trunk measurement system (Formetric 4D, DIERS, Germany), a 3D image processing apparatus with high resolution for vertebrae, were used to measure 3D trunk images of the vertebrae and pelvis obliquity, as well as static balance ability. [Result] The MWM group showed a significantly better Balance than the control group. In addition, the results of the left/right and the front/rear balance abilities were significantly better than those of the control group. [Conclusion] This study proved that a combination of mobilization with movement and functional training was effective in reducing pelvis malposition and pain, and improving static stability control.

  8. Legacy of Polio—Use of India’s Social Mobilization Network for Strengthening of the Universal Immunization Program in India

    Deutsch, Nicole; Singh, Vivek; Curtis, Rod; Siddique, Anisur Rahman

    2017-01-01

    Abstract The Social Mobilization Network (SMNet) has been lauded as one of the most successsful community engagement strategies in public health for its role in polio elimination in India. The UNICEF-managed SMNet was created as a strategy to eradicate polio by engaging >7000 frontline social mobilizers to advocate for vaccination in some of the most underserved, marginalized, and at-risk communities in India. This network focused initially on generating demand for polio vaccination but later expanded its messaging to promote routine immunization and other health and sanitation interventions related to maternal and children’s health. As an impact of the network’s interventions, in collaboration with other eradication efforts, these high-risk pockets witnessed an increase in full routine immunization coverage. The experience of the SMNet offers lessons for health-system strengthening for social mobilization and promoting positive health behaviors for other priority health programs like the Universal Immunization Program.

  10. Interactions of Transportation and Telecommunications Behaviors

    Dholakia, N.; Mundorf, N.; Dholakia, R. R.; Xiao, J. J.

    2002-05-01

    This project was designed as a social science complement to the engineering studies supported by the University of Rhode Island (URI) Transportation Center (URITC). The project developed a behavioral knowledge base about the actual and intended transport and telecommunications behaviors of transportation users, with a particular focus on southern Rhode Island. Background studies, drawing from literature on telecommuting and travel behavior, led to the development of a generalized framework to understand the transport-telecom interactions. In particular, we developed working papers dealing with transport aspects of e-retailing and distance education. In the empirical part of this project, two major field studies were completed. The first of these was a survey of URI students, probing their car travel, carpool, bus use, and Internet use behaviors. The students were surveyed first by telephone, selected randomly from a list obtained from the Register's office. A total of 220 students responded to the telephone survey. Characteristics of the telephone survey respondents are shown in Appendix B. This was supplemented by an in-class survey of 107 students conveniently selected from the courses taught by the research faculty. This supplementary questionnaire probed the students more deeply regarding their motivations for transportation and technology use issues. The second major field study was a mail survey of southern Rhode Island residents. In this survey, we not only investigated actual travel and transport behaviors but also measured attitudes towards the environment and alternative transport and telecommuting solutions. At the time of writing this report, about 850 individuals had responded to our mail questionnaire. Characteristics of the resident sample are described in Appendix B. The results have laid the groundwork for our second year project where we plan to study the impact of specific interventions on transportation and telecommuting attitudes and intentions.

    2017-07-01

    Full Text Available This study investigates whether the new online registration and admission system implemented at a Tertiary Institution in Gauteng, South Africa, was successful and effective. The Institution under study is the first in South Africa to implement this new online registration system from the 3rd of January 2013 using a system called the Integrated Tertiary Software (ITS Mobile information system. The information system enables students to apply online without physically visiting the institution and provides the status of their registration and admission applications via their smartphones. A total of one hundred 1st year students and ten personnel were sampled to respond to self-completed questionnaires. The efficiency of this new online system was evaluated using the Technology Acceptance Model (TAM, the Web of System Performance (WOSP model and the DeLone and McLean IS Success model as well as the indicators of system ineffectiveness and attributes on the basis of which an information system was evaluated. Key findings emerging from the data analysis and interpretation show that the new online system met the expectations of most staff and students with the exception of few staff members and students. The findings show that the investment made on the new online registration system is benefiting the University and students. The implementation of the new online registration and admission system was a success to a larger extent because the expectations of most users were met. The online system is effective as it was evaluated using the conventional measuring methods and resulted in positive outcomes.

  16. Telecommunications: international opportunities for power utilities

    Lewis, A. [Teleglobe Canada, Ottawa, ON (Canada)

    1996-08-01

    International telecommunications services markets and trends were reviewed in an effort to identify business opportunities for Canadian power utilities. With increasing deregulation in the U.S. and Canada, and other countries around the globe, market opportunities are beginning to open up. In monopoly markets opportunities exist in providing dual infrastructures to upgrade both the power delivery services (frequently poor), and telecommunications. Billing, collection and customer service expertise might be other marketable commodities, perhaps packaged as part of a network provision project as a service to existing power and telecommunications service providers. In countries with directed competition markets local partnerships may be the only vehicle for entering the market. In managed competition markets opportunities were said to exist in cellular radio technology, as well as in switched telephone service, local, long distance, or international. In general, opportunities outside telecommunications-rich North America were considered to have better potential, due to rapid deregulation and higher current growth rates in telecommunications. Careful examination and research of the political and business environment prior to entering any of the potentially fertile areas was advised.

  18. Substituting telecommunications for travel - Feasible or desirable

    Van Vleck, E. M.

    1974-01-01

    This paper reviews recent advances in telecommunications and examines the detailed structure of travel to estimate the feasibility of substituting telecommunications for various travel objectives. The impact of travel is analyzed from a social, economic, energy, and pollution standpoint to assess the desirability of substitution. Perhaps 35-50% of the nation's travel could, in theory, be replaced by very advanced telecommunications (such as a much improved large-screen teleconferencing network), but public resistance would be massive. Much economic dislocation would result since, for example, over 25% of retail sales are travel-related. The energy savings would be modest since only 25% of the nation's energy is consumed by transportation. However, all pollution would be reduced substantially since transportation accounts for 75% of the carbon monoxide, 60% of the hydrocarbon, and 55% of the nitrogen oxide pollution in the nation. Problems related to the implementation of large-scale substitution are discussed.

  19. Telecommunications companies and health in West Africa: the issues.

    Ankri, R; Maroune, M-H

    2017-11-01

    West Africa still faces important public health issues today: improving the health infrastructure, compensating for the lack of medical personnel, and bringing the rural "lost-to-follow-up" population into an inclusive healthcare system. At the same time, the boom in the mobile telephone market is providing important business opportunities for telecommunications companies in this field, leading to the rapid propagation of eHealth solutions. Thus, the telecom companies' technical innovations enable the creation of digital health solutions adapted to the specific needs of the West African market. The companies can thus increase their business through eHealth and simultaneously generate positive externalities (a healthier population), meeting the goals of their corporate social responsibility policies. We will see how these companies, aware of this opportunity, build these solutions and they meet the challenges they will confront.

  20. TELECOMMUNICATIONS INFRASTRUCTURE AND GDP /JIPP CURVE/

    Mariana Kaneva

    2016-07-01

    Full Text Available The relationship between telecommunications infrastructure and economic activity is under discussion in many scientific papers. Most of the authors use for research and analysis the Jipp curve. A lot of doubts about the correctness of the Jipp curve appear in terms of applying econometric models. The aim of this study is a review of the Jipp curve, refining the possibility of its application in modern conditions. The methodology used in the study is based on dynamic econometric models, including tests for nonstationarity and tests for causality. The focus of this study is directed to methodological problems in measuring the local density types of telecommunication networks. This study offers a specific methodology for assessing the Jipp law, through VAR-approach and Granger causality tests. It is proved that mechanical substitution of momentary aggregated variables (such as the number of subscribers of a telecommunication network at the end of the year and periodically aggregated variables (such as GDP per capita in the Jipp�s curve is methodologically wrong. Researchers have to reconsider the relationship set in the Jipp�s curve by including additional variables that characterize the Telecommunications sector and the economic activity in a particular country within a specified time period. GDP per capita should not be regarded as a single factor for the local density of telecommunications infrastructure. New econometric models studying the relationship between the investments in telecommunications infrastructure and economic development may be not only linear regression models, but also other econometric models. New econometric models should be proposed after testing and validating with sound economic theory and econometric methodology.

  2. A statistical model for telecommunication link design

    Yuen, J. H.

    1975-01-01

    An evaluation is conducted of the current telecommunication link design technique and a description is presented of an alternative method, called the probability distribution method (PDM), which is free of the disadvantages of the current technique while retaining its advantages. The PDM preserves the simplicity of the design control table (DCT) format. The use of the DCT as a management design control tool is continued. The telecommunication link margin probability density function used presents the probability of achieving any particular value of link performance. It is, therefore, possible to assess the performance risk and other tradeoffs.

    Conventional Global Positioning System (GPS) receivers operate well in open-sky environments. But their performance degrades in urban canyons, indoors and underground due to multipath, foliage, dissipation, etc. To overcome such situations, several enhancements have been suggested such as Assisted GPS (A-GPS). Using this approach, orbital parameters including ephemeris and almanac along with reference time and coarse location information are provided to GPS receivers to assist in acquisition of weak signals. To test A-GPS enabled receivers high-end simulators are used, which are not affordable by many academic institutions. This paper presents an economical A-GPS supplement for inexpensive simulators which operates on application layer. Particularly proposed solution is integrated with National Instruments' (NI) GPS Simulation Toolkit and implemented using NI's Labview environment. This A-GPS support works for J2ME and Android platforms. The communication between the simulator and the receiver is in accordance with the Secure User Plane Location (SUPL) protocol encapsulated with Radio Resource Location Protocol (RRLP) applies to Global System for Mobile Communications (GSM) and Universal Mobile Telecommunications System (UMTS) cellular networks.

  8. Students and Teachers’ Perceptions into the Viability of Mobile Technology Implementation to Support Language Learning for First Year Business Students in a Middle Eastern University

    2017-04-01

    Full Text Available Advancements in technology have enabled us to learn, adapt and exploit our skills and knowledge in new ways.  Appreciating the potential of technology may yet give growth and enrich the process of language education, particularly through a student-centred mobile learning environment. Consequently, a constructivist approach to learning can create tremendous possibilities for both language learners and teachers. By exploiting the affordances of mobile technologies and the Internet, a new platform of learning or Mobile Assisted Language Learning (MALL can be realised, through which learners truly learn to learn.  Yet, while many of today’s language institutions and places of learning have begun to understand the potential presented by mobile technology as a tool and resource to content and language development, apprehension may still exist among educational practitioners, learners and senior management.  Such apprehension may stem from a lack of understanding in fully appreciating the opportunities and affordances posed by MALL in creating a support structure to learning and teaching excellence. This may be particularly true within developing countries such as those found in the Middle East. Consequently, set in a Saudi university context, the purpose of this study is to investigate learners’ and teachers’ perceptions towards the proposed implementation of a MALL programme, while exploring whether the promotion of mobile technologies could assist learning and become a viable support structure in teaching English as a second language.  Interviews were conducted with three English instructors who teach on the first year Business English programme at the university. The study also analysed 191 student participants who completed a Likert scale questionnaire designed to explore their mobile learning experiences, attitudes and perceptions towards the proposed MALL programme in their educational context. The findings from the student

  2. Antecedents of customer switching intention in the Ghanaian telecommunications industry

    Kwame Simpe Ofori

    2017-11-01

    Full Text Available The telecommunications industry continues to experience fierce competition due to the growth in subscribers and the rapid development of new technologies in the sector. With that hindsight, this study explores the dimensionality of factors that affect mobile phone subscribers’ intention to switch operators. Survey data was collected from 235 mobile phone network subscribers and analyzed using the Partial Least Square Approach to Structural Equation Modelling (SEM. The SEM model was assessed based on the measurement model and the structural model. Factor Loadings, Cross Loadings, Average Variance Extracted Cronbach’s alpha, and Composite reliabilities of the latent variables examined showed that the measurement model exhibited sufficient reliability, discriminant validity and convergent validity. Assessment of the Structural model shows that 77% of the variation in Satisfaction is explained by our model (R2 = 0.77. Furthermore, 18% (R2 = 0.18 of the variation in Intention to Switch was explained by the model. Stone-Geiser Q2 for the endogenous showed that the proposed Structural Equation Model exhibited sufficient predictive relevance. Conclusions were drawn with practical implications of the results also discussed.

    Iwasaki, H. [Central Research Institute of Electric Power Industry, Tokyo (Japan)

    1997-06-01

    This paper presents future prospects on development of different mobile communication systems operated by public communications operators, and discusses their application to power utilities. For automobile and cellular telephones, discussions are being made on the code division multiple access (CDMA) system which multiplexes and transmits information by using tally codes. Influence of noise decreases, and so does the need of retransmission due to code errors. Higher speed transmission than conventional systems may be expected. The system can be utilized for transmitting still images, such as for status of construction being carried out by power utility companies. For PHS, a discussion will start on 32 to 64-kbps transmission in fiscal 1997. By using the system together with an image compression technology, the system may be expected of utilization as a moving image transmission method for supporting site works by utility companies. The low and medium orbit satellite communications whose use is scheduled to start shortly can be utilized as construction and emergency disaster communication networks for mountainous areas and islands. Movements around the frequency band utilization and communication systems of IMT-2000 are becoming more complex. The Japanese proposal plans transmission of moving images, whereas more diverse utilization can be expected, such as for voice, data and images, in areas where no ground communication facilities are available for electric power operations. 16 refs., 4 figs., 3 tabs.

  4. Telecommunications as a means to access health information: an exploratory study of migrants in Australia

    Louise Greenstock

    2012-10-01

    Full Text Available Background. Health policies increasingly promote e-health developments (e.g., consumers’ access to online health information to engage patients in the health care. In order to make these developments available for culturally and socially diverse communities, not only do Internet accessibility, literacy and e-health literacy need to be taken into account, but consumers’ preferences and information seeking behaviours for accessing health information have also to be understood. These considerations are crucial when designing major new health policy directions, especially for migration destination countries with culturally diverse populations, such as Australia. The aim of this study was to examine how people from a culturally and linguistically diverse (CALD community use telecommunications (phone, mobile, Internet to access health information. Design and Methods. A case study was conducted using a questionnaire exploring the use of telecommunications to access health information among CALD people. The study was carried out at a community health centre in a socially and economically disadvantaged area of Melbourne, a city of 4 million people with a large CALD and migrant population. Questionnaires were translated into three languages and interpreters were provided. Fifty-nine questionnaires were completed by users of the community health centre. Results. Most of the CALD participants did not have access to the Internet at home and very few reported using telecommunications to access health information. Conclusions. The findings of the study suggest that telecommunications are not necessarily perceived to be an important channel for accessing health information by members of the CALD community.

  6. Describing Long-Term Electricity Demand Scenarios in the Telecommunications Industry: A Case Study of Japan

    Yusuke Kishita

    2016-01-01

    Full Text Available Due to the rapid expansion of information and communication technology (ICT usage, the telecommunications industry is faced with a challenge to promote green ICT toward achieving a low-carbon society. One critical obstacle in planning long-term strategies for green ICT is the uncertainty of various external factors, such as consumers’ lifestyle and technological advancement. To tackle this issue, this paper employs a scenario planning method to analyze electricity consumption in the telecommunications industry, where both changes in various external factors and energy-saving measures are assumed. We propose a model to estimate future electricity consumption of the telecommunications industry using a statistical approach. In a case study, we describe four scenarios that differ in the diffusion of ICT and the technological advancement of ICT equipment in order to analyze the electricity consumption in Japan’s telecommunications industry to 2030. The results reveal that the electricity consumption in 2030 becomes 0.7–1.6-times larger than the 2012 level (10.7 TWh/year. It is also shown that the most effective measures to reduce the electricity consumption include improving the energy efficiency of IP (Internet Protocol communication equipment and mobile communication equipment.

  9. Disaster management and mitigation: the telecommunications infrastructure.

    Patricelli, Frédéric; Beakley, James E; Carnevale, Angelo; Tarabochia, Marcello; von Lubitz, Dag K J E

    2009-03-01

    Among the most typical consequences of disasters is the near or complete collapse of terrestrial telecommunications infrastructures (especially the distribution network--the 'last mile') and their concomitant unavailability to the rescuers and the higher echelons of mitigation teams. Even when such damage does not take place, the communications overload/congestion resulting from significantly elevated traffic generated by affected residents can be highly disturbing. The paper proposes innovative remedies to the telecommunications difficulties in disaster struck regions. The offered solutions are network-centric operations-cap able, and can be employed in management of disasters of any magnitude (local to national or international). Their implementation provide ground rescue teams (such as law enforcement, firemen, healthcare personnel, civilian authorities) with tactical connectivity among themselves, and, through the Next Generation Network backbone, ensure the essential bidirectional free flow of information and distribution of Actionable Knowledge among ground units, command/control centres, and civilian and military agencies participating in the rescue effort.

  10. Japan nurtures telecommunications on classic formula

    Davis, Neil

    1987-03-01

    As in other industrial sectors, Japanese telecommunications organizations export significantly more products than they import, even when substantial cost-savings can be realized. One example is optical fibers, which some Japanese service companies do not buy from outside suppliers who have taken advantage of economies of scale. Nippon Telephone and Telegraph, until recently a common carrier, is meeting increasing competition from newly-formed indigenous telecommunications subsidiaries who are taking advantage of fiber optics and microwave communications capabilities. Various cooperative projects with U.S. companies are described, noting the tendency of Japanese manufacturers to cease relationships with U.S. companies when Japanese products become competitive and also the necessity of U.S. firms to gain political cooperation from the Japanese government in order to make sales in Japan.

  11. Advances in VRLA battery technology for telecommunications

    Misra, Sudhan S. [SPM Consultants LLC, 112 Gwynmont Circle, North Wales, PA 19454 (United States)

    2007-05-25

    Wide scale use of the newly emergent VRLA (valve-regulated lead-acid) battery in telecommunication applications and the subsequent problems encountered early in their deployment history spurred intense efforts to improve the design as a continuous endeavor. After implementing improvements to battery placement and containment design to prevent the sudden onset of thermal runaway, the focus of the development work has been on cell internals. These include improved grid and strap alloys, superior AGM (absorbent glass mat) separator that retains compression in the cell, use of beneficial additives to the active materials and the need to avoid contaminants that promote detrimental side reactions. These improvements are now resulting in a vastly superior VRLA experience in the telecommunication applications. To further improve the reliability demanded by today's communication and internet environment VRLA battery installations should include continuous cell/module and system monitoring similar to that incorporated in competing advanced battery systems under development.

  13. Bio-inspired Autonomic Structures: a middleware for Telecommunications Ecosystems

    Manzalini, Antonio; Minerva, Roberto; Moiso, Corrado

    Today, people are making use of several devices for communications, for accessing multi-media content services, for data/information retrieving, for processing, computing, etc.: examples are laptops, PDAs, mobile phones, digital cameras, mp3 players, smart cards and smart appliances. One of the most attracting service scenarios for future Telecommunications and Internet is the one where people will be able to browse any object in the environment they live: communications, sensing and processing of data and services will be highly pervasive. In this vision, people, machines, artifacts and the surrounding space will create a kind of computational environment and, at the same time, the interfaces to the network resources. A challenging technological issue will be interconnection and management of heterogeneous systems and a huge amount of small devices tied together in networks of networks. Moreover, future network and service infrastructures should be able to provide Users and Application Developers (at different levels, e.g., residential Users but also SMEs, LEs, ASPs/Web2.0 Service roviders, ISPs, Content Providers, etc.) with the most appropriate "environment" according to their context and specific needs. Operators must be ready to manage such level of complication enabling their latforms with technological advanced allowing network and services self-supervision and self-adaptation capabilities. Autonomic software solutions, enhanced with innovative bio-inspired mechanisms and algorithms, are promising areas of long term research to face such challenges. This chapter proposes a bio-inspired autonomic middleware capable of leveraging the assets of the underlying network infrastructure whilst, at the same time, supporting the development of future Telecommunications and Internet Ecosystems.

    Telemedicine is traditionally associated with the use of very expensive and bulky telecommunications equipment along with substantial bandwidth requirements (128 kilobytes per second [kbps] or greater). Telementoring is an educational technique that involves real-time guidance of a less experienced physician through a procedure in which he or she has limited experience. This technique has been especially dependent on the aforementioned requirements. Traditionally, telemedicine and telementoring have been restricted to technically sophisticated sites. The telemedicine applications through the existing telecommunication infrastructure has not been possible for underdeveloped parts of the world. Telemedicine and telementoring were applied using low-bandwidth mobile telemedicine applications to support a mobile surgery program in rural Ecuador run by the Cinterandes Foundation and headed by Edgar Rodas, MD. A mobile operating room traveled to a remote region of Ecuador. Using a laptop computer equipped with telemedicine software, a videoconferencing system, and a digital camera, surgical patients were evaluated and operative decisions were made over low-bandwidth telephone lines. Similarly, surgeons in the mobile unit in Ecuador were telementored by an experienced surgeon located thousands of miles away at Yale University School of Medicine. Five preoperative evaluations were conducted from Sucua to Cuenca, Ecuador, with excellent clinical correlation. Additionally, a laparoscopic cholecystectomy was successfully telementored from the department of surgery at Yale University School of Medicine to the mobile surgery unit in Ecuador. The telementored surgery was performed using a telephone line with a baud rate of 12 kbps. Mobile, low-bandwidth telemedicine applications used in the proper technical and clinical algorithms can be very effective in supporting remote health care delivery efforts. Advantages of such applications include increased cost-effectiveness by

  15. Use of satellite telecommunications for telemedicine

    Tamkovich, Gennady

    1991-01-01

    The use of space telecommunications facilities in the interests of medicine should establish a reliable and timely connection between the specialists involved and access for each of them to information sources the need. Since a certain global-scale program should be implemented for this goal to be achieved, one of the top-priority tasks is to determine appropriate orbital facilities for telecommunications as well as appropriate areas and countries for them, outlining the territories where portable data receive/transport records can be placed and stations that are cheap and simple enough to operate can be stored. Eventually the satellite telecommunications system should encourage health workers to unite in a world community on the basis of a regular and efficient information exchange with the goal of protecting the health of man and the peace of Earth. This goal could only be achieved by gradually removing differences in the domain of medical education and information in different regions over the globe, by providing a possibility of rapid and coordinated access to the information on medical problems of interest on the global scale, as well as by coordinating the discussion and solution of all problems associated with the development and progress of the satellite communications system.

  16. Book Review of "Getting Ahead: Social Mobility, Public Housing and Immigrant Networks" 2011. New York University Press, by Silvia Dominguez.

    Stephen J. Sills

    2011-11-01

    Full Text Available Sylvia Dominguez’s book "Getting Ahead: Social mobility, Public Housing, and Immigrant Networks" fits neatly in the tradition of Cecilia Menjivar, Pierette Hondaneu-Sotelo, Mary Romero and other recent longitudinal ethnographic studies of immigrant women’s social support networks. Dominquez attempts in this text to bridge the gap between studies of urban poverty and public housing and that of the assimilation and immigrant incorporation literatures. She notes that the "literature on social mobility among residents of high poverty neighborhoods is unproductively divided into theories to explain the experience of low income African Americans living in areas of concentrated black poverty , and less prolific literature to explain the experiences of immigrants living in similarly segregated neighborhoods."

    2007-01-01

    This essay analyzes the data of Chinese telecommunication market, telecommunication investments and investment benefits over the past 20 years. On the basis of these data, the essay reviews Chinese changing telecommunication policies and discusses the major events in the course of China's telecommunication development. It is argued that telecommunication policies, regime backgrounds and market demand characteristics have a significant impact on investment decision mode in telecommunication industry. The evolution of network investments decision mode in China's telecommunication has corresponded to the transformation of these key factors. Considering the special events in the development of Chinese telecommunication as divisions, the essay discusses three stages of the evolution of investments decision mode in China's telecommunication. With the firm environment and problems that Chinese telecommunication operators have been facing since 2000 analyzed. it is demonstrated that Chinese telecommunication operators should change their mode of investment decision into the "profit-oriented investment decision mode" in order to achieve a high growth performance in the capital market,. This investment decision mode will result in increase of the investment profit with limited investment capital. The main procedure of profit-oriented investment decision mode is set out, which is abstracted to a mathematical model eventually.

    2015-09-01

    Full Text Available This study examines the critical influence of advertising on consumer choice of telecommunication services in Nigeria. The advertisement played a key role in providing the consumers with product information. The study investigates the effect of marketing medium of telecommunication as a proxy for advertisement on preference of telecommunication services as a proxy for consumer choice in Nigeria. The Binary Logit Model (BLM and descriptive analytical frameworks are used to evaluate the statistical importance of advertisement, quality of services, income of the consumer, product’s self and related service charges for a consumer choice of telecommunication services through Wald test. The findings show that product’s self service charge and service quality are statistically significant for a consumer choice of telecommunication services in Nigeria at 1 percent significance level. And, related product’s service is statistically significant for a consumer choice of telecommunication services in Nigeria at 5 percent significance level. While advertisement and income of the consumer are statistically significant for a consumer choice of telecommunication services in Nigeria at 10 percent. The study concludes that advertisement is important for the choice of telecommunication services in Nigeria but having less impact. And, product’s self service charge and service quality are hugely significant for the choice of telecommunication services in Nigeria. Therefore, the sector of telecommunications needs more investment in advertisement so as to have telecommunications’ products information spread in order to stimulate the increase in demand for telecommunication services in Nigeria.

    2015-05-01

    Full Text Available This article arises from a research work entitled “Institutional Diagnosis: Equity Relations between Men and Women at the National University: Second Phase,” performed in 2011 by the Institute of Women’s Studies. This study aims at “Analyzing, from a gender perspective, the social and labor conditions and positioning of those academic employees at the National University in order to determine the gender inequity gaps that restrict the full development of men and women.” This research was conducted by reviewing listings of people elected for decision-making positions from 1976 to mid-2009. This information was provided by the National University Elections Commission (TEUNA3, for its Spanish acronym. Interviews were made to women who, for the first time, held senior positions at this university and who are still working here. Among the main findings of this research is the gradual increase of women holding senior positions such as Rector, Dean and Director. Once the interviews had been transcribed, we proceeded to prepare the categories of analysis. When the university was first founded, most Dean’s positions were held by men. But throughout time –in the 2000s, equity regarding the number of men and women in this category was observed. In terms of management positions, faculties with a significant number of male academic employees   -such as Social Sciences, Earth and Ocean Sciences, and Natural Sciences, have little representation of women in these positions. This article finds that women positively evaluate their experience in senior positions since it has helped them grow and gain personal and professional confidence. They also highlighted a number of achievements and contributions made to their corresponding academic units.

  1. Fire protection for telecommunications central offices

    McKenna, L.A. Jr.

    1990-01-01

    The provision of continuous, uninterrupted telecommunications service is vital to modern life. In order to provide uninterrupted service to customers, a service continuity program has been in place with AT and T for many years. This program integrates many different protection strategies and plans, each designed to mitigate one of the many threats to service continuity. The fire protection program implemented within AT and T is a part of this service continuity program. In the design of this program, a number of unusual problems had to be addressed due to the service continuity requirements. Typical solutions to fire protection problems (ignition prevention, detection, and suppression) which are embodied in building and fire prevention codes are inadequate to provide service continuity. This presentation outlines the basic arrangement of a telecommunications central office, the specific fire protection problems encountered, the fire protection philosophy developed through the use of a systems approach, and the implementation of the fire protection program. Special emphasis is placed on the strategies employed in lieu of more traditional fire protection schemes and the stimuli for selecting them

  2. Protected interoperability of telecommunications and digital products

    Hampel, Viktor E.; Cartier, Gene N.; Craft, James P.

    1994-11-01

    New federal standards for the protection of sensitive data now make it possible to ensure the authenticity, integrity and confidentiality of digital products, and non-repudiation of digital telecommunications. Under review and comment since 1991, the new Federal standards were confirmed this year and provide standard means for the protection of voice and data communications from accidental and wilful abuse. The standards are initially tailored to protect only `sensitive-but-unclassified' (SBU) data in compliance with the Computer Security Act of 1987. These data represent the majority of transactions in electronic commerce, including sensitive procurement information, trade secrets, financial data, product definitions, and company-proprietary information classified as `intellectual property.' Harmonization of the new standards with international requirements is in progress. In the United States, the confirmation of the basic standards marks the beginning of a long-range program to assure discretionary and mandatory access controls to digital resources. Upwards compatibility into the classified domain with multi-level security is a core requirement of the National Information Infrastructure. In this report we review the powerful capabilities of standard Public-Key-Cryptology, the availability of commercial and Federal products for data protection, and make recommendations for their cost-effective use to assure reliable telecommunications and process controls.

    ENGLISH ABSTRACT: With the embracing of neV'( management philosophies or redesigned processes, it is becoming a popular opinion that often the practical problem lies with the implementation of the new concept, rather than with the concept itself. By focussing on certain generic critical actions, chances of successful implementation increases for any new philosophy or re-engineered process. This article discusses such critical success actions, or implementation drivers as experience in a BPR project at Siemens Telecommunications.

    AFRIKAANSE OPSOMMING: 'n Gewilde siening ten opsigte van die bekendstelling van nuwe bestuursfilosofiee, of implementering van herontwerpde prosesse, is dat die probleem gewoonlik Ie by die implementering daarvan, eerder as by die beginsels van die bestuursfilosofie wat geimplementeer word . Deur op generies kritieke faktore te konsentreer, kan die kanse op suksesvolle implementering van bykans enige bestuursfilosofie of herontwerpde proses verbeter word.

  4. Displays enabling mobile multimedia

    Kimmel, Jyrki

    2007-02-01

    With the rapid advances in telecommunications networks, mobile multimedia delivery to handsets is now a reality. While a truly immersive multimedia experience is still far ahead in the mobile world, significant advances have been made in the constituent audio-visual technologies to make this become possible. One of the critical components in multimedia delivery is the mobile handset display. While such alternatives as headset-style near-to-eye displays, autostereoscopic displays, mini-projectors, and roll-out flexible displays can deliver either a larger virtual screen size than the pocketable dimensions of the mobile device can offer, or an added degree of immersion by adding the illusion of the third dimension in the viewing experience, there are still challenges in the full deployment of such displays in real-life mobile communication terminals. Meanwhile, direct-view display technologies have developed steadily, and can provide a development platform for an even better viewing experience for multimedia in the near future. The paper presents an overview of the mobile display technology space with an emphasis on the advances and potential in developing direct-view displays further to meet the goal of enabling multimedia in the mobile domain.

  5. Evolving the Convergence of Telecommunication and TV Services over NGN

    Adel Al-Hezmi

    2008-01-01

    Full Text Available The convergence of telecommunication, cable TV, and broadcast networks towards the Internet technology will enable the provision of emerging multimedia services as well as the integration of rich communication capabilities with TV services. However, enabling efficient delivery of interactive personalized multimedia services with mobility support requires an advanced overlay control framework. The IP Multimedia Subsystem (IMS offers the basic functions to manage multimedia sessions over different access networks. This paper outlines current standardization activities that address the provisioning of TV services over IP networks—known as IPTV—and proposes a novel end-to-end overall architecture based on IMS that enables the delivery of converged multimedia services. Furthermore, the paper presents the FOKUS Media Interoperability Lab as a reference implementation of this framework which covers a widespread spectrum of converged interactive scenarios. The final section gives an impression of the system performance by providing the end-to-end signaling delay of a session setup for live TV service delivered over unicast transmission mode.

    The rural sector of the US is examined from the point of view of whether telecommunications technology can augment the development of rural education. Migratory farm workers and American Indians were the target groups which were examined as examples of groups with special needs in rural areas. The general rural population and the target groups were examined to identify problems and to ascertain specific educational needs. Educational projects utilizing telecommunications technology in target group settings were discussed. Large scale regional ATS-6 satellite-based experimental educational telecommunications projects were described. Costs and organizational factors were also examined for large scale rural telecommunications projects.

  11. Space Telecommunications Radio System STRS Cognitive Radio

    Briones, Janette C.; Handler, Louis M.

    2013-01-01

    Radios today are evolving from awareness toward cognition. A software defined radio (SDR) provides the most capability for integrating autonomic decision making ability and allows the incremental evolution toward a cognitive radio. This cognitive radio technology will impact NASA space communications in areas such as spectrum utilization, interoperability, network operations, and radio resource management over a wide range of operating conditions. NASAs cognitive radio will build upon the infrastructure being developed by Space Telecommunication Radio System (STRS) SDR technology. This paper explores the feasibility of inserting cognitive capabilities in the NASA STRS architecture and the interfaces between the cognitive engine and the STRS radio. The STRS architecture defines methods that can inform the cognitive engine about the radio environment so that the cognitive engine can learn autonomously from experience, and take appropriate actions to adapt the radio operating characteristics and optimize performance.

  13. Experimental and numerical assessment of low-frequency current distributions from UMTS and GSM mobile phones

    Gosselin, Marie-Christine; Kühn, Sven; Kuster, Niels

    2013-01-01

    The evaluation of the exposure from mobile communication devices requires consideration of electromagnetic fields (EMFs) over a broad frequency range from dc to GHz. Mobile phones in operation have prominent spectral components in the low-frequency (LF) and radio-frequency (RF) ranges. While the exposure to RF fields from mobile phones has been comprehensively assessed in the past, the LF fields have received much less attention. In this study, LF fields from mobile phones are assessed experimentally and numerically for the global system for mobile (GSM) and universal mobile telecommunications system (UMTS) communication systems and conclusions about the global (LF and RF) EMF exposure from both systems are drawn. From the measurements of the time-domain magnetic fields, it was found that the contribution from the audio signal at a normal speech level, i.e., −16 dBm0, is the same order of magnitude as the fields induced by the current bursts generated from the implementation of the GSM communication system at maximum RF output level. The B-field induced by currents in phones using the UMTS is two orders of magnitude lower than that induced by GSM. Knowing that the RF exposure from the UMTS is also two orders of magnitude lower than from GSM, it is now possible to state that there is an overall reduction of the exposure from this communication system.

  15. High temperature superconductors applications in telecommunications

    Kumar, A.A.; Li, J.; Zhang, M.F.

    1994-01-01

    The purpose of this paper is twofold: to discuss high temperature superconductors with specific reference to their employment in telecommunications applications; and to discuss a few of the limitations of the normally employed two-fluid model. While the debate on the actual usage of high temperature superconductors in the design of electronic and telecommunications devices-obvious advantages versus practical difficulties-needs to be settled in the near future, it is of great interest to investigate the parameters and the assumptions that will be employed in such designs. This paper deals with the issue of providing the microwave design engineer with performance data for such superconducting waveguides. The values of conductivity and surface resistance, which are the primary determining factors of a waveguide performance, are computed based on the two-fluid model. A comparison between two models-a theoretical one in terms of microscopic parameters (termed Model A) and an experimental fit in terms of macroscopic parameters (termed Model B)-shows the limitations and the resulting ambiguities of the two-fluid model at high frequencies and at temperatures close to the transition temperature. The validity of the two-fluid model is then discussed. Our preliminary results show that the electrical transport description in the normal and superconducting phases as they are formulated in the two-fluid model needs to be modified to incorporate the new and special features of high temperature superconductors. Parameters describing the waveguide performance-conductivity, surface resistance and attenuation constant-will be computed. Potential applications in communications networks and large scale integrated circuits will be discussed. Some of the ongoing work will be reported. In particular, a brief proposal is made to investigate of the effects of electromagnetic interference and the concomitant notion of electromagnetic compatibility (EMI/EMC) of high T c superconductors

    2014-01-01

    Work was done to measure radiation exposure of the populace in Kaduna metropolis from radiation emitted from global satellite communication masts. Base stations were surveyed in residential, school and office areas. Parameters sampled include the electric field strength, magnetic field strength, power density and ionizing radiation dose rate of the 20 surveyed masts belonging to four service providers. The instruments deployed include the Rf- EMF strength meter Model 480836 used to measure the first three parameters and Radiation Monitor Radex RD 1503 used to determine the forth parameter. The result obtained in this work was compared with the limits set by international regulatory bodies. Our result shows that electromagnetic and ionizing radiation exposures from the surveyed masts are far below the standard limits. Based on this, the population in Kaduna metropolis is not subjected to any adverse health effects from the Global System of Mobile Communication/Universal Mobile Telecommunication System masts at the moment.

  8. The Value Estimation of an HFGW Frequency Time Standard for Telecommunications Network Optimization

    Harper, Colby; Stephenson, Gary

    2007-01-01

    The emerging technology of gravitational wave control is used to augment a communication system using a development roadmap suggested in Stephenson (2003) for applications emphasized in Baker (2005). In the present paper consideration is given to the value of a High Frequency Gravitational Wave (HFGW) channel purely as providing a method of frequency and time reference distribution for use within conventional Radio Frequency (RF) telecommunications networks. Specifically, the native value of conventional telecommunications networks may be optimized by using an unperturbed frequency time standard (FTS) to (1) improve terminal navigation and Doppler estimation performance via improved time difference of arrival (TDOA) from a universal time reference, and (2) improve acquisition speed, coding efficiency, and dynamic bandwidth efficiency through the use of a universal frequency reference. A model utilizing a discounted cash flow technique provides an estimation of the additional value using HFGW FTS technology could bring to a mixed technology HFGW/RF network. By applying a simple net present value analysis with supporting reference valuations to such a network, it is demonstrated that an HFGW FTS could create a sizable improvement within an otherwise conventional RF telecommunications network. Our conservative model establishes a low-side value estimate of approximately 50B USD Net Present Value for an HFGW FTS service, with reasonable potential high-side values to significant multiples of this low-side value floor.

  11. The Case for Deep Space Telecommunications Relay Stations

    Chandler, Charles W.; Miranda, Felix A. (Technical Monitor)

    2004-01-01

    Each future mission to Jupiter and beyond must carry the traditional suite of telecommunications systems for command and control and for mission data transmission to earth. The telecommunications hardware includes the large antenna and the high-power transmitters that enable the communications link. Yet future spacecraft will be scaled down from the hallmark missions of Galileo and Cassini to Jupiter and Saturn, respectively. This implies that a higher percentage of the spacecraft weight and power must be dedicated to telecommunications system. The following analysis quantifies this impact to future missions and then explores the merits of an alternative approach using deep space relay stations for the link back to earth. It will be demonstrated that a telecommunications relay satellite would reduce S/C telecommunications weight and power sufficiently to add one to two more instruments.

  13. A personalized mobile patient guide system for a patient-centered smart hospital: Lessons learned from a usability test and satisfaction survey in a tertiary university hospital.

    Yoo, Sooyoung; Jung, Se Young; Kim, Seok; Kim, Eunhye; Lee, Kee-Hyuck; Chung, Eunja; Hwang, Hee

    2016-07-01

    The present study focused on the design, implementation, and evaluation of a personalized mobile patient guide system that utilizes smart phones, indoor navigation technology and a hospital information system (HIS) to address the difficulties that outpatients face in finding hospital facilities, recognizing their daily treatment schedule, and accessing personalized medical and administrative information. The present study was conducted in a fully digitized tertiary university hospital in South Korea. We developed a real-time location-based outpatient guide system that consists of Bluetooth access points (APs) for indoor navigation, an Android-based guide application, a guide server, and interfaces with the HIS. A total of 33 subjects and 43 outpatients participated in the usability test (UT) and the satisfaction survey, respectively. We confirmed that the indoor navigation feature can be applied to outpatient departments with precision using a position error test. The participants in the UT completed each scenario with an average success rate of 67.4%. According to the results, we addressed the problems and made improvements to the user interface by providing users with context-based guidance information. The satisfaction rating of the system was high, with an average score of 4.0 out of 5.0, showing its utility as a patient-centered hospital service. The innovative mobile patient guide system for outpatients is feasible and can be successfully implemented to provide personalized information with high satisfaction. Additionally, the issues identified and lessons learned from our experiences regarding task scheduling, indoor navigation, and usability should be considered when developing the system.

  14. Spatial electromagnetic field intensity modelling of global system for mobile communication base stations in the Istanbul Technical University Ayazaga campus area.

    Boz, Kubra; Denli, Hayri Hakan

    2018-05-07

    The rapid development of the global system for mobile communication services and the consequent increased electromagnetic field (EMF) exposure to the human body have generated debate on the potential danger with respect to human health. The many research studies focused on this subject have, however, not provided any certain evidence about harmful consequences due to mobile communication systems. On the other hand, there are still views suggesting such exposure might affect the human body in different ways. To reduce such effects to a minimum, the International Commission on Non-Ionizing Radiation Protection (ICNIRP) has declared boundary values for the energy released by the base stations, which are the main source of the electromagnetic fields. These values are accepted by many countries in various parts of the world. The aim of this study was to create EMF intensity maps for the area covered by Istanbul Technical University (ITU) and find areas of potential risk with regard to health considering the current situation and future trends. In this study, the field intensities of electromagnetic signals issued at the frequencies of 900 and 1800 MHz were measured in V/m at 29 pre-specified survey points using a spectrum analyzer (Spectran HF-6065). Geographic information systems and spatial interpolation techniques were used to produce EMF intensity maps. Three different spatial interpolation methods, minimum mean square error, Radial Basis and Empirical Bayesian Kriging, were compared. The results were geographically analyzed and the measurements expressed as heat maps covering the study area. Using these maps, the values measured were compared with the EMF intensity standards issued by ICNIRP. The results showed that the exposure levels to the EMF intensities were all within the ICNIRP limits at the ITU study area. However, since the EMF intensity level with respect to human health is not known, it is not possible to confirm if these levels are safe or not.

  2. The Media of Relativity: Einstein and Telecommunications Technologies.

    Canales, Jimena

    2015-07-01

    How are fundamental constants, such as "c" for the speed of light, related to the technological environments that produce them? Relativistic cosmology, developed first by Albert Einstein, depended on military and commercial innovations in telecommunications. Prominent physicists (Hans Reichenbach, Max Born, Paul Langevin, Louis de Broglie, and Léon Brillouin, among others) worked in radio units during WWI and incorporated battlefield lessons into their research. Relativity physicists, working at the intersection of physics and optics by investigating light and electricity, responded to new challenges by developing a novel scientific framework. Ideas about lengths and solid bodies were overhauled because the old Newtonian mechanics assumed the possibility of "instantaneous signaling at a distance." Einstein's universe, where time and space dilated, where the shortest path between two points was often curved and non-Euclidean, followed the rules of electromagnetic "signal" transmission. For these scientists, light's constant speed in the absence of a gravitational field-a fundamental tenet of Einstein's theory-was a lesson derived from communication technologies.

  3. Telecommunications, politics, economics, and national sovereignty: A new game

    Bugliarello, G.

    1996-12-31

    The impact of telecommunications on politics, economics and national sovereignty is creating a new game. Political and economic power may operate over the same territory, as in the now-rare case of isolated economies, but, more often, their domains do not coincide. Increasingly, telecommunications create major challenges for countries preoccupied with issues of national sovereignty because the national state has only a limited ability to control these intrinsic and at times potentially destabilizing powers of telecommunications and the {open_quotes}telecommunities{close_quotes} they make possible. As many traditional aspects of sovereignty are becoming weakened by telecommunications, and as the intense dynamics of networks and the expansion of telecommunities revolutionize business and politics, there is a need to prevent the situation from becoming chaotic and uncontrollable, even while recognizing the possibilities of enhanced opportunities. This requires focusing on a more flexible conception of sovereignty which can enhance the state`s attractiveness for telecommunications infrastructure, while addressing issues of ethics and morality in the new telecommications environment. A new, broad socio-technological research agenda needs to be developed - with the ultimate purpose of providing society with the tools to play the new game and thrive. 10 refs., 3 tabs.

  8. A Self-Directed Mobile Intervention (WaznApp) to Promote Weight Control Among Employees at a Lebanese University: Protocol for a Feasibility Pilot Randomized Controlled Trial.

    Bardus, Marco; Hamadeh, Ghassan; Hayek, Bouchra; Al Kherfan, Rawan

    2018-05-16

    Overweight and obesity have become major health problems globally with more than 1.9 billion overweight adults. In Lebanon, the prevalence of obesity and overweight is 65.4% combined. Risk factors of obesity and overweight are preventable and can be addressed by modifications in the environment and in an individual's lifestyle. Mobile technologies are increasingly used in behavioral, self-directed weight management interventions, providing users with additional opportunities to attain weight control (weight loss, weight gain prevention, etc). Mobile apps may allow for the delivery of Just-in-Time Adaptive Interventions (JITAIs), which provide support through skill building, emotional support, and instrumental support, following the participants' progress. A few commercially available apps offer JITAI features, but no studies have tested their efficacy. The primary objective of this study is to examine the feasibility of a self-directed weight loss intervention, targeting employees of an academic institution, using a virtual coaching app with JITAI features (Lark) and a self-help calorie-counting app (MyFitnessPal). The secondary objective is to estimate the effects of the intervention on main study outcomes. This study is a single-center, parallel, randomized controlled trial with 2 study arms (intervention and control). Participants will be randomly allocated in equal proportions to the intervention (Lark) and control groups (MyFitnessPal). To be eligible for this study, participants must be employed full- or part-time at the university or its medical center, able to read English, have a smartphone, and be interested in controlling their weight. Recruitment strategies entail email invitations, printed posters, and social media postings. We will assess quantitative rates of recruitment, adherence, and retention, self-reported app quality using the user version of the Mobile App Rating Scale. We will also assess changes in weight-related outcomes (absolute weight

  10. Space Telecommunications Radio System (STRS) Compliance Testing

    Handler, Louis M.

    2011-01-01

    The Space Telecommunications Radio System (STRS) defines an open architecture for software defined radios. This document describes the testing methodology to aid in determining the degree of compliance to the STRS architecture. Non-compliances are reported to the software and hardware developers as well as the NASA project manager so that any non-compliances may be fixed or waivers issued. Since the software developers may be divided into those that provide the operating environment including the operating system and STRS infrastructure (OE) and those that supply the waveform applications, the tests are divided accordingly. The static tests are also divided by the availability of an automated tool that determines whether the source code and configuration files contain the appropriate items. Thus, there are six separate step-by-step test procedures described as well as the corresponding requirements that they test. The six types of STRS compliance tests are: STRS application automated testing, STRS infrastructure automated testing, STRS infrastructure testing by compiling WFCCN with the infrastructure, STRS configuration file testing, STRS application manual code testing, and STRS infrastructure manual code testing. Examples of the input and output of the scripts are shown in the appendices as well as more specific information about what to configure and test in WFCCN for non-compliance. In addition, each STRS requirement is listed and the type of testing briefly described. Attached is also a set of guidelines on what to look for in addition to the requirements to aid in the document review process.

    A flight-qualified implementation of a Software Defined Radio (SDR) Operating Environment for the JPL-SDR built for the CoNNeCT Project has been developed. It is compliant with the NASA Space Telecommunications Radio System (STRS) Architecture Standard, and provides the software infrastructure for STRS compliant waveform applications. This software provides a standards-compliant abstracted view of the JPL-SDR hardware platform. It uses industry standard POSIX interfaces for most functions, as well as exposing the STRS API (Application Programming In terface) required by the standard. This software includes a standardized interface for IP components instantiated within a Xilinx FPGA (Field Programmable Gate Array). The software provides a standardized abstracted interface to platform resources such as data converters, file system, etc., which can be used by STRS standards conformant waveform applications. It provides a generic SDR operating environment with a much smaller resource footprint than similar products such as SCA (Software Communications Architecture) compliant implementations, or the DoD Joint Tactical Radio Systems (JTRS).

    As mines utilize more automation in mining operations to improve efficiency and safety, a corresponding increasing demand is placed on the transport of information. Some of the recent technological advances in underground telecommunications are described for various data, voice and video applications. In particular, two new innovative underground communication systems are described, one with highspeed data at 30 Mbps and the other for mine-wide evacuation and safety applications. The high-speed data system incorporates state-of-the-art data networking technologies and the existing leaky-cable, narrow-band radio channels. The new system provides over the same basic infrastructure - the highspeed data network at 30 Mbps TCP/IP Ethernet with 100 Base-T interconnection, plus 32 narrow-band radio channels. The second system is a system for mine-wide evacuation with 'through-the-earth' communication infrastructure. Emergency situations can be communicated to and from all the miners within seconds through a central control location. The technology involved does not require leaky cable or any other similar transmission media installation. Many applications are possible, including warning miners of emergency situations, mine rescue operation to communicate with trapped miners, and regular reporting from miners working alone.

    2001-10-01

    The tremendous demands from social market are pushing the booming development of mobile communications faster than ever before, leading to plenty of new advanced techniques emerging. With the converging of mobile and wireless communications with Internet services, the boundary between mobile personal telecommunications and wireless computer networks is disappearing. Wireless networks of the next generation need the support of all the advances on new architectures, standards, and protocols. Mobility management is an important issue in the area of mobile communications, which can be best solved at the network layer. One of the key features of the next generation wireless networks is all-IP infrastructure. This paper discusses the mobility management schemes for the next generation mobile networks through extending IP's functions with mobility support. A global hierarchical framework model for the mobility management of wireless networks is presented, in which the mobility management is divided into two complementary tasks: macro mobility and micro mobility. As the macro mobility solution, a basic principle of Mobile IP is introduced, together with the optimal schemes and the advances in IPv6. The disadvantages of the Mobile IP on solving the micro mobility problem are analyzed, on the basis of which three main proposals are discussed as the micro mobility solutions for mobile communications, including Hierarchical Mobile IP (HMIP), Cellular IP, and Handoff-Aware Wireless Access Internet Infrastructure (HAWAII). A unified model is also described in which the different micro mobility solutions can coexist simultaneously in mobile networks.

    2002-01-01

    Near-miss event reporting systems have a successful history in managing risk in industries such as medicine, aviation, nuclear power, and the petrochemical industry. By treating events of customer dissatisfaction as accidents, near-miss event reporting systems designed to reduce risks to safety in hazardous environments may be borrowed by the telecommunications industry. The system chosen for this study was the Prevention and Recovery Information System for Monitoring and Analysis (PRISMA), developed by the Eindhoven University of Technology (EUT). The purpose of this study was to determine the feasibility of applying PRISMA as a tool to reduce risks to customer dissatisfaction. Participants in the project included the EUT Safety Management Group, a consultant, and six Network Service Managers from a telecommunications company whose duties included responding to customer complaints. Twenty-three incidents were investigated with an average of 5.9 root causes arising from 2.9 process owners per event. Causal trees were generated for each incident and root causes were classified according to the Eindhoven Classification Model (ECM). The distribution of 135 root causes was 50% organizational, 32% human, 16% technical and 2% unclassifiable. The participants were successful in executing the functional steps of PRISMA in response to incidents of customer dissatisfaction. This study established the suitability of PRISMA as a tool for managing risks to customer satisfaction within the telecommunications domain

    Chang Wook Jeong

    Full Text Available OBJECTIVES: We developed a mobile application-based Seoul National University Prostate Cancer Risk Calculator (SNUPC-RC that predicts the probability of prostate cancer (PC at the initial prostate biopsy in a Korean cohort. Additionally, the application was validated and subjected to head-to-head comparisons with internet-based Western risk calculators in a validation cohort. Here, we describe its development and validation. PATIENTS AND METHODS: As a retrospective study, consecutive men who underwent initial prostate biopsy with more than 12 cores at a tertiary center were included. In the development stage, 3,482 cases from May 2003 through November 2010 were analyzed. Clinical variables were evaluated, and the final prediction model was developed using the logistic regression model. In the validation stage, 1,112 cases from December 2010 through June 2012 were used. SNUPC-RC was compared with the European Randomized Study of Screening for PC Risk Calculator (ERSPC-RC and the Prostate Cancer Prevention Trial Risk Calculator (PCPT-RC. The predictive accuracy was assessed using the area under the receiver operating characteristic curve (AUC. The clinical value was evaluated using decision curve analysis. RESULTS: PC was diagnosed in 1,240 (35.6% and 417 (37.5% men in the development and validation cohorts, respectively. Age, prostate-specific antigen level, prostate size, and abnormality on digital rectal examination or transrectal ultrasonography were significant factors of PC and were included in the final model. The predictive accuracy in the development cohort was 0.786. In the validation cohort, AUC was significantly higher for the SNUPC-RC (0.811 than for ERSPC-RC (0.768, p<0.001 and PCPT-RC (0.704, p<0.001. Decision curve analysis also showed higher net benefits with SNUPC-RC than with the other calculators. CONCLUSIONS: SNUPC-RC has a higher predictive accuracy and clinical benefit than Western risk calculators. Furthermore, it is easy
