An Efficient Traffic Information Forwarding Solution for Vehicle Safety Communications on Highways

Efficiently propagating adequate and effective traffic information to drivers helps increase driving safety and reduces traffic jams on highways. To achieve this, we designed an overlay solution that considers the challenges of propagating multisource information caused by vehicle mobility and multihop forwarding. The overlay solution is composed of a mobility-adaptive information reduction scheme (IR scheme) and a vehicle-adaptive cluster-to-cluster multihop forwarding method (VAC method). The IR scheme creates a mobility-adaptive cluster to represent local traffic information. The purpose of the scheme is to simplify individual high-speed movements and reduce large amounts of information broadcasts. Based on the results of the IR scheme, the VAC method selects the optimal relay node of the intercluster forwarding pair to increase the efficiency of multihop propagation. In the simulation, we compared network performance with two other protocols by defining three objective metrics of driving-perceived quality under different traffic scenarios and analyzed the results. Furthermore, we explored protocol overhead, broadcasting reduction ratio, and technological deviations to verify the advantages and efficiencies of our solution. The simulation proves that our solution is an efficient multisource and multihop forwarding framework that allows well-connected vehicular networks to disseminate a higher degree of correct traffic information, particularly for highway safety-related information.

Typology of Web 2.0 spheres: Understanding the cultural dimensions of social media spaces

It has taken the past decade to commonly acknowledge that online space is tethered to real place. From euphoric conceptualizations of social media spaces as a novel, unprecedented and revolutionary entity, the dust has settled, allowing for talk of boundaries and ties to real-world settings. Metaphors have been instrumental in this pursuit, shaping perceptions and affecting actions within this extended structural realm. Specifically, they have been harnessed to architect Web 2.0 spaces, be it chat rooms, electronic frontiers, homepages, or information highways for policy and practice. While metaphors are pervasive in addressing and normalizing new media spaces, there is less effort channeled into organizing these digital domains along cultural lines to systematize and deepen understandings of its histories, agencies and communities. Hence, this article proposes a framework that reveals dominant cultural dimensions of Web 2.0 spaces through a five-fold typology: (1) utilitarian-driven, (2) aesthetic-driven, (3) context-driven, (4) play-driven and (5) value-driven. This effort capitalizes and transfers mappings of actors and networks from real to virtual space to capture and organize diverse cultural (re)productions.

Browsing the information highway while driving: three in-vehicle touch screen scrolling methods and driver distraction

Distraction effects of three alternative touch screen scrolling methods for searching music tracks on a mobile device were studied in a driving simulation experiment with 24 participants. Page-by-page scrolling methods with Buttons or Swipe that better facilitate resumption of visual search following interruptions were expected to lead to more consistent in-vehicle glance durations and thus on less severe distraction effects than Kinetic scrolling. As predicted, Kinetic scrolling induced decreased visual sampling efficiency and increased visual load compared with Swipe, increased experienced workload compared with both Buttons and Swipe, as well as decreased lane-keeping accuracy compared with baseline. However, Buttons did not significantly excel Kinetic with any metric but on subjective ratings. Based on the results, we do not recommend the use of kinetic scrolling with in-vehicle touch screen displays in the manner used in the experiment. Instead, page-by-page swiping seems to suit significantly better for in-vehicle displays due to its systematic nature and low levels of pointing accuracy required for scrolling the pages.

Another Lane on the Information Highway? A Case Study of Experimenting with Text Message Reference

This article examines the process of researching, adapting, and implementing a text message reference service and the conclusions reached after nearly 10 months of continuous service. This experiment involved a single BlackBerry passed in a rotating schedule among librarians to gauge student interest in a text reference service. Although implementing this service allowed the library to be at the technological forefront, this is a service that would be better provided via a software interface. Furthermore, the text message reference service needed a stronger marketing campaign to make students aware of this option.

The Design of Information Platform Structure Used in Expressway Management Based on SOA Frame

On the basis of the study on the expressway management business flow as well as the SOA architecture concept, this paper designs the overall framework for a systematical expressway management information platform, which includes network of 3 levels, grading processing, comprehensive monitoring, comprehensive information application management, web portal and security system, and then designs the overall technical frame of this platform. Road administration is the core part of highway administration and the concentrated reflection of external highway administrative management. In addition to the approval of highway property, construction, maintenance and management, its main contents also involve the highway maintenance, highway entrance fee management and other road maintenance. It covers a wide range and there is so much information of deferent types to be processed and used. Although domestic and foreign roads and road administration departments have some information management systems in use, some are special highway road administration information systems[1,2], and some are highway comprehensive information management systems[3], the integrated comprehensive highway information management contents are lack of research, and the professional, comprehensive, open road administration information platform has not been established yet. Therefore, the author conducted the design of constructing advanced road administration information platform structure. This platform uses the service oriented architecture (SOA), integrates advanced information network technology, data communications monitoring and transmission technology, electronic control technology, computer processing technique with 3S, PDA and other advanced technologies, so that it is effectively integrated and used in the highway information management. The construction of the platform will realize the effective and scientific management for highways business, ensuring that the highways are unblocked, and maintaining the road property and rights of highways, thus promoting the development of the industrial management information.

EMPIRE and health website recommendations: Technologies of control

There is limited literature and empirical data that attempts to theorise or elucidate the repercussions that have eventuated from the e-health phenomenon. Therefore, this exploratory study will identify how modern forms of communication technologies (that is, the Internet, World Wide Web) are being used by Transnational Corporations (that is, pharmaceutical companies) in an attempt to globalise economic markets, online health information, services and products. To assist in the theorisation of these research findings, this article draws upon the work of Hardt and Negri to critically examine the influences that motivate health professionals to undertake a health website recommendation, in terms of globalisation, capitalism and information imperialism. Hardt and Negri, in their exploration of the development and rise of a networked digital information highway, more commonly called ‘The Internet’, give particular attention to the concepts of cyberspace and the impacts of a new form of global juridical sovereignty, known as EMPIRE. Attention will be directed towards outlining how the dominant forces of our time (that is, global pharmaceutical companies and the networked digital highway) have influenced online health information access, and subsequently twenty-first century health-care delivery.

Study on the Relationship between Stress-Deformation and Space-Time in Hejiagou Tunnel Construction

Based on the technological features of highway tunnel information design and construction，the relationships between stress-deformation and space-time were studied profoundly, combining closely to the monitoring practice of Heijiagou highway tunnel in Beijing to Chengde express way. With the results in rock mass stress monitoring, the adjustment law of stress was analyzed; and the relationships among stress and rock mass classification, burial depth and geologic conditions were disclosed. A profound study about the features of the relationship between rock mass deformation and space-time was carried out, as well. Finally, the application of monitoring results on rock mass classification, hazard forecasting and determination of the best time to construct the secondary supporting was introduced.

A management system for road information properties

The volume of expressway information resources in Japan is increasing, together with the expansion of routes in service. Introduction of information technology (IT) has accelerated computerisation of activities, but it has been difficult to keep them well organised due to the diversification of work and the highly developed quality of the various data. The pace of computerisation cannot keep up with the data that is accumulated daily. Therefore, most of the data is stored on paper or in individual electronic data processes. In order to overcome these problems and use the data efficiently, we have constructed a data management model through the business life cycle of expressways, which is based on modelling road structure.

Internet In Global Settings: A New Look At International Marketing

The growing use of e-commerce has opened up a new territory of ongoing communication between consumers and manufacturers around the World. Both parties are now able to target each other regardless of their national boundaries. Accordingly, more and more companies are getting into the international arena and hoping that they can get nicer shares of the potential business volume. Many firms are trying to identify and target specific market segments globally by building a network of Internet sites around the World. While creating a network may just be the beginning, it appears to be a rather successful venture. These businesses are finding out that e-commerce may be a very effective way to reach those markets with similar attributes globally. Considering the continuously increasing speed of technology in the information highway, one can only assume that there will be even more markets attainable in the near future. The question is who will be there first to cover these markets, and more importantly, who will be better prepared to cover them properly.

The golden mean

PurposeThis column aims to explore the consequences of making uninformed technology decisions in the context of strategic planning for digital library environments.Design/methodology/approachThe paper explores the consequences of making uninformed technology decisions.FindingsThis column recommends a balanced approach for funding digital library initiatives.Practical implicationsGiven the rapidly changing landscape of the information highway, it is difficult especially for decision makers in library organizations to plan well for digital initiatives. Cutting edge services such as cloud‐based computing offer a mirage of hope in many instances and need to be carefully scrutinized before the first penny has been allocated from a library budget.Originality/valueThis column prescribes a cautionary note for digital libraries of the twenty‐first century. While many vendor‐based services (such as “software as a service”) are initially attractive, vendor lock‐in and lack of control over critical library services can prove fatal.

A Service-Oriented Architecture for Networked Highway

Today's highway manager and citizen are navigating the ever-increasing amount of sensor data available from a wide variety of in-situ and dynamic environmental sensors. However, it's hard to share, interoperate and fuse those heterogeneous data from different fields, and it's even hard to linked spaces together as a whole. The main reason is that not we inadequate of data or processing, but the mechanism we can aggregate and cooperate the resources seamless. Aiming to solve the question, we propose a SOA (Service Oriented Architecture) based services framework for networked highway. This framework first extends annotation of service, regarding sensor resources, data resources, and processing resources as services. Final, those services are linked together to establish a powerful highway information system.

Re-reading the Notion of “Convergence” in Light of Recent Changes to the Culture and Communication Industries in Canada

Due to its multifaceted nature and its appropriation by different social actors, “convergence” is a complex concept. In the 1990s it had its heyday when there was a lot of talk about “information highways.” In this text, the author revisits convergence through an examination of recent changes to the culture and communication industries in Canada. The article reveals that convergence is always a horizon and that it includes several interrelated processes that advance slowly. In some cases, it is even possible to speak of “divergence.”

Enlightenment of “The Spiral of Silence” Theory to Enterprise Crisis Management

formation of network society multiplies crisis spreading of enterprises, so crisis management in network times has become a significant task for enterprises to discover and study. Herein we claim The Spiral of Silence Theory continues to play a role in network spreading, which provides enterprise crisis management with a new perspective. th Century, as excellent representation of high technology international network and information high way provide people with capacious space for production, living and activity, and our society gradually steps into network society. Modern enterprises have to bear crisis consciousness, i.e. think of danger in times of peace and prepare for a rainy day, in mind and sufficiently consider and emphasize enterprise crisis management in order to win business competition. We propose in this paper that The Spiral of Silence Theory provides enterprise crisis management with a new perspective. 1. Brief Introduction of The Spiral of Silence Theory The Spiral of Silence was primarily shown in the paper published on Journal of Communication Research by Elisabeth Noelle-Neumann, German sociologist, in 1974. She generalized this theory comprehensively in the book The Spiral of Silence: Public Opinion—Our Social Skin published in 1980. This theory is based on the following case. Allensbach Research Institution of Germany made a study in 1965 on the coming national selection. During the research process, the two Parties always run neck and neck in the selection. first estimate result showed the two Parties both have opportunity to win. However 6 months later, i.e. 2 months before the selection, the winning possibility of the Christianity Democracy Party to the other Party is 4:1. last 2 weeks before the selection, the Christianity Democracy Party won 4% of votes, but the Society Democracy Party lost 5% of that. In the selection of the same year, the Christianity Democracy Party won finally leading with 9% over the other one. concept of the spiral of came from the confusion brought by this selection, and scholars have been trying to interpret it. basis idea could be described as follows: Avoid social punishment due to isolation. People tend to observe surrounding before pointing out an idea. A person is likely to an opinion boldly and actively if one feels that one is in the or opinions; while he is likely to turn to be silent or echo due to environmental pressure if one feels that one is in the minority or opinions. emphasized by public media are underground and spread widely, so they are easily perceived as or opinions. During the spiral expanding of silence of disadvantageous opinions and voice of advantageous opinions, advantageous majority opinions in social life—consensus, comes into being. Neumann proposed a hypothesis: most of individuals will choose public media opinion to avoid isolation from holding particular attitude and belief. One is not willing to his own opinion for fear of isolation. Actually this cognition almost exists in everyone's mind both in western and eastern society, especially for the Chinese people experiencing Culture Revolution. However Professor Neumann caught this phenomenon and proposed hypothesis: dominant and increasingly supported are more advantageous, while the opposite side tends to lose step by step. Thus, the situation of one party with but the other with turns out to be a spiral process which constantly establishes main opinion from one opinion. If public media participate in this process, the spiral will be formed more quickly and obviously. Neumann claimed not until 18 th

La infancia en los actuales contextos tecnológicos. Una reinterpretación de las prácticas en el proceso de construcción de la corporeidad infantil

The present paper takes child discourse as its starting point. The everyday expression “me meto en Internet” (i.e. “I get on the web”), as used by boys and girls in a grade school in a district of Barcelona, suggests the idea that the media and the information highway are inscribed in current childhood experiences. Talking with fifth grade boys and girls in a series of intentional dialogues whose purpose was to ask about the school’s role in the construction of children’s corporeity, it was made clear that we needed a new analytical stance in order to unravel the interpretations of eleven- and twelve-year-old subjects about their own corporeity, taking into account the universally disruptive intrusion of the media. From a constructionist point of view (Guba and Lincoln, 1994), this paper describes how this irruption represents a gate to access certain practices that call for an adult exploration. The text in this study is in itself a narrative account – i.e. a ‘story’ in the sense that Clandinin and Connelly (2000) ascribe to this word – in which my voice is combined with the students’ discourse, as well as with various theoretical schools of thought. The paper finds its inspiration in the assumption that childhood, as a social category, no longer resembles the image that we adults take for granted as a faithful representation. Our outdated image of childhood, drawing from our life experience and a professional training forged in past contexts, is but an idealized representation of children as dependants – beings completely conditioned by the adults on whom they rely for support. This image, however, has been shattered by the presence of the media and other technological novelties that foster new ways of being, feeling and living. Technology summons up new possible worlds for child agents, allowing for more complex ways to think about themselves while interleaving new processes of identification and un-identification between discourses and practices that make up their selfknowledge and also offering them the consent and the space to be. Operatively, a body is not only a pillar of support, but it also provides a certain degree of character that goes into the making of a possible identity. The ultimate purpose of this paper is to explore the embodied subjectivity of today’s childhood in order to understand how child subjects reinterpret themselves when facing media discourses and practices, and who provides them with information and entertainment that spreads and reaffirms the image of an ideal body.Key words: agency processes, corporeity, technological contexts, narrative inquiry.
