Mervyn, Kieran. "The use of mobile information and communicaton technology to address social exclusion." Thesis, University of Leeds, 2011. http://ethos.bl.uk/OrderDetails.do?uin=uk.bl.ethos.551364.
Full textAbstract:
Social exclusion was a key political issue of the New Labour administration and an issue of importance internationally. In recent years mobile information and communication technologies (MlCT) and self-service government have been promoted as a mechanism to address social exclusion. The purpose of this thesis is to investigate the influence of MICT on under-served people. In the research two MICT-enabled approaches to service provision for socially excluded residents are explored: Halton 's centrally-planned approach and Preston's laissez-faire, non-interventionist model. Both offer alternative technological approaches to significant social problems. This study is informed by a qualitative and interpretive paradigm. An exploratory research design using extended case studies was used in order to assess whether MICT can redress problems associated with social exclusion or offer new approaches to solving significant social issues. Case exploration was facilitated through the use of activity theory. Activity theory places both user activity and the broader activity system(s) at the hub of analysis. In this respect, human activities are shaped by the social, cultural and historical context of MICT use. The research identified three themes which are relevant to policy and practice: the complexity of information needs mean that that self service government is a flawed concept; rather than direct access to information the excluded need direct access to human information intermediaries; and the environments in which m-government services are delivered are fundamentally different types of social spaces which create new dilemmas and challenges.

Thesis (MComm)--Stellenbosch University, 2012.ENGLISH ABSTRACT: Enterprises and more specifically, marketing departments, function in a complex global market, while trying to deliver products and services to satisfy the needs of consumers. It is estimated that by 2013, enterprises will be spending $4.75 trillion and consumers $330 billion by means of commercial transactions over the Internet, and that by 2050 most transactions – if not all transactions – will be e-commerce based (Laudon and Traver, 2010:1-7). The 24-hour access to a global network of markets has brought about two major challenges for most enterprises. Firstly, the Internet as a publishing platform has exponentially increased the creation and sharing of information, which has significantly increased consumers’ search cost; and secondly, as more electronic word-of-mouth (EWOM) is being generated online, a significant amount of power and influence over enterprises has shifted to consumers (Chen, Wu and Yoon, 2004:716-722; Tapscott and Williams, 2008:52-53). Ultimately, enterprises are challenged to harness the power of EWOM for more successful e-commerce strategies and increased market share. Given previous studies, it was possible to extend the theoretical framework of EWOM communication in the fields of Internet marketing and online consumer behaviour. The purpose of this study was to create two models that could measure, over time, the impact of EWOM review communication on an e-commerce platform, specifically with regard to review credibility and sales levels. In using a non-probability judgement sampling procedure, it emerged that EWOM reviews do indeed influence the sales levels of e-commerce platform Amazon.com, and that certain review factors (platform, text length, time and star ratings) significantly influenced the credibility of Amazon.com and Barnesandnoble.com reviews. Furthermore, it was concluded that the overall credibility of reviews increases over time as more and more online users have the ability to scrutinise it. When Amazon.com and Barnesandnoble.com’s reviews were compared to each other, the results indicated that Amazon.com had more reviews than Barnesandnoble.com, and that the reviews posted at Amazon.com had on average longer text lengths and were found to be more helpful than the reviews at Barnesandnoble.com. The study's major contribution is that it provides wide-ranging guidelines for usability and user experience design, sales and inventory forecasting, as well as benchmark statistics for marketing campaigns.
AFRIKAANSE OPSOMMING: Ondernemings, en in die besonder bemarkingsafdelings, funksioneer in ‘n komplekse globale mark, in hulle strewe om voortdurend produkte en dienste te lewer wat voldoen aan verbruikersbehoeftes. Na raming sal ondernemings teen die jaar 2013 $4.75 triljoen en verbruikers $330 biljoen spandeer aan kommersiële transaksies oor die Internet, terwyl die meeste, indien nie alle transaksies, teen die jaar 2050 gebaseer gaan wees op e-handel (Laudon en Traver, 2010:1-7). Die 24-uur toegang tot ‘n globale netwerk van markte het twee hoofuitdagings vir die meeste ondernemings tot gevolg. In die eerste plek het die Internet as uitgewersplatform die skep en verspreiding van inligting eksponensieel laat toeneem, wat verbruikers se soekkoste noemenswaardig verhoog het; en tweedens, namate elektroniese hoorsê aanlyn gegenereer word, het ‘n beduidende hoeveelheid mag en invloed van ondernemings na die verbruiker verskuif (Chen, Wu en Yoon, 2004:716-722; Tapscott en Williams, 2008:52-53). Ondernemings word dus uitgedaag om die impak van elektroniese hoorsê (electronic word-of-mouth) te ontgin om meer suksesvolle e-handelstrategieë en verhoogde winste te verkry. In die lig van vorige studies was dit moontlik om die tradisionele teoretiese raamwerk van hoorsêkommunikasie uit te brei na die veld van Internet-bemarking en verbruikersgedrag. Die doel van hierdie studie was om twee modelle te ontwikkel wat, met verloop van tyd, die impak van elektroniese hoorsêkommunikasie op ‘n e-handelplatform kon meet, met spesifieke verwysing na resensiegeloofwaardigheid en verkoopsvlakke van boeke. Deur die gebruik van ‘n nie-waarskynlikheidsoordeel steekproefprosedure, het die studie bevind dat elektroniese hoorsêresensies inderdaad ‘n invloed het op die verkoopsvlakke van elektroniese e-handelplatforms en dat sekere resensiefaktore (platform, teks, lengte, tyd en stergradering) die geloofwaardigheid van elektroniese e-handelplatforms se resensies beduidend beïnvloed het. Verder is die gevolgtrekking gemaak dat die oorhoofse geloofwaardigheid van resensies toeneem namate al hoe meer aanlynverbruikers die vermoë het om dit onder oë te kry. In ‘n vergelyking tussen die resensies van twee e-handel platforms Amazon.com en Barnesandnoble.com, is bevind dat Amazon.com meer resensies as Barnesandnoble.com het, dat die resensies op Amazon.com gemiddeld langer tekste het, en ook meer behulpsaam uit ‘n verbruikersoogpunt is as die resensies op Barnesandnoble.com. Die hoofbydrae van hierdie studie is dat dit riglyne bied aan e-handelplatforms om hul kliënte se verbruikerservaring beter te verstaan, en om sodoende beter verkope- en voorraadvooruitskattings te kan maak. Verder bied die studie ook riglyne t.o.v. doeltreffende bemarkingsveldtogte vir e-handelplatforms.

Full textAbstract:
Depuis la fin de la deuxième guerre, l'idéologie du développement a progressivement imposé sa lecture essentialiste et évolutionniste du monde. Malgré les échecs et les déceptions qui ont mis en exergue le caractère non heuristique de la conception unilinéaire des sociétés, la notion n'a pas complètement perdu de sa force mobilisatrice. À travers des inventions et des branchements divers et constants, elle a survécu à la critique par le ré-enchantement de la notion et ses variations thématiques. En effet, au détour des années 80, pour asseoir davantage sa légitimité, le débat autour du développement, non seulement a embrassé les questions environnementales mais s'est fragmenté, en se déclinant autour de plusieurs thèmes et sous-thèmes tels que la lutte contre la pauvreté, l'alphabétisation, le désendettement, la lutte contre le sida… Dans les pays africains, notamment au Cameroun, cette recomposition féconde de la notion a trouvé, dans les enjeux de l'agriculture, un cadre idéal d'articulation et d'expression. Dans la même logique évolutive, la communication, indissociablement liée au développement, a connu des modélisations successives, recadrant progressivement ses dispositifs et ses stratégies, pour susciter et accompagner les changements sociaux. C'est ce qui explique l'avènement d'une communication participative, motivée par une prise en compte de l'altérité et l'assomption des identités culturelles.À partir d'une expérience de la vulgarisation agricole, tributaire de l'inventivité thématique du développement, cette recherche examine la complexité de la dynamique participative avec ses enjeux identitaires. En se fondant sur la stratégie des acteurs, ce travail met en lumière la dimension structurante des identités culturelles consécutive à une démarche praxéologique où la communication s'inscrit dans une aventure herméneutique sous-tendue par une logique d'archéologie existentielle. Par le fait même, la communication adopte une nouvelle posture épistémologique en devenant « lieu » stratégique d'interprétation du vécu et de transgression de la doxa du développementSince the end of the Second World War, the ideology of development has progressively imposed an essentialist and evolutionalist interpretation of the world. In spite of breakdowns and disappointments which have brought out a non-heuristic nature of the unilinear conception of societies, this notion has not totally lost some of its stirring strength. Through decades of inventions and various and continuous connections, it has survived criticism by the re-enchantment of the notion of its thematic variations. Indeed, in the early 1980's, in order to better establish its legitimacy, debate around development / growth has not only embraced environmental questions but has also fragmented, coming into a variety of themes and sub-themes such as the fight against poverty and AIDS, elimination of illiteracy, debt reducing, and so on. In African countries, in Cameroun precisely, this fruitful recomposition of the notion has found a perfect frame for structure and expression in the agricultural stakes. In the same evolutionary dynamic, communication, inextricably linked to development, has known successive modeling, progressively refocusing its devices and strategies to arouse and support social changes. That explains the advent of participative communication, helped by the notion of otherness and the assumption of cultural identities.From an agricultural popular experiment dependent on thematic inventiveness of development, this research considers the complexity of participative dynamics with its issues about identity. Based on the strategy used by active protagonists, this work highlights the structuring dimension of cultural identities resulting of a praxeological approach, in which communication is part of a logic of an underlying hermeneutic adventure, being part of a logics of existential archaeology. For this very reason, communication adopts a new epistemological point of view, becoming the strategic “place” of interpretation of actual experience and of transgression of the doxa of development

Le contexte général de ce travail est l'étude du comportement d'applications parallèles, représentées par un graphe de précédence. La programmation de telles applications dépend fortement des supports d'exécution. Nous présentons et discutons les principaux modèles d'exécution et leur influence sur les problèmes d'ordonnancement des tâches du programme parallèle. Nous étudions en détail quatre problèmes d'ordonnancement sur des modèles d'exécution où le coût de communication est pris en compte. Nous proposons une solution pour un problème à grain très fin, le problème du sac à dos, sur hypercube dans un modèle d'exécution synchrone où le coût de communication est implicite. Nous étudions l'ordonnancement de chaînes sur un modèle à gros grain de communication, le modèle BSP. Nous démontrons qu'ici la recherche d'un ordonnancement optimal est un problème NP-difficile. Nous proposons des solutions avec un compromis entre le nombre de phases de communication/synchronisation et le temps d'inactivité dans chaque processeur. Les deux derniers problèmes étudiés concernent des techniques qui permettent de réduire l'impact du coût des communications inter processeurs. La première technique considère la duplication des tâches. Nous proposons un algorithme de liste avec garantie de performance 2 pour les problèmes à petit temps de communication sur un nombre limité de processeurs. Le deuxième méthode consiste à optimiser les phases de communication en ordonnançant les transmissions de messages. La recherche de la solution optimale étant NP-difficile, nous proposons plusieurs heuristiques.

Full textAbstract:
Doctor of Philosophy (PhD)Television is the favoured news source for most Australians and is regarded as having the potential to influence public opinion. From its inception however, television has been regarded as ill-suited to cover economic and business issues because of a perceived reliance on visual material and an inability to deal with complex issues. This tyranny of vision has been mitigated by technological developments such as electronic news gathering (ENG) and satellites that provide large amounts of varied material as well as improvements in production tools that assist the visual presentation of abstract concepts. The presentation of complex issues has also been enhanced by the increased skills and knowledge among newsworkers. Economic and business news has become a staple in television news programs and has evolved from ritualised reporting of data such as market indices and exchange rates to a genre that shares broader news values such as consequence, conflict, proximity, human interest, novelty, prominence, political controversy and scandal. Economic and business news also shares the normal imperatives of television such as a strong reliance on scheduled occasions and reliable and prolific sources. In between occasions of economic, business and political controversy or scandal, these programs are able to rely on a steady supply of economic, business and investment information. Dedicated economic and business segments and programs and now even whole channels meet two sets of demands. One is those of niche audiences seeking news and information on economic and business conditions, economic debate and policy making, the activities of economic and business leaders and an opportunity to hear and observe economic and business leaders. The other is from broadcasters seeking to maximise their profits by attracting viewers in the AB demographic (those with the greatest disposal income) to otherwise poorly-performing time slots, by broadcasters seeking an inexpensive and dependable supply of programming material and by broadcasters seeking to promote their institutional role and specific programs through presenting material that is followed up by other media. Economic and business reports however, continue to portray issues in a limited way that neglects business’s interaction with workers and the larger social environment. Economic events are often framed as political competition. These reports present a hierarchy of sources and privilege political and business elites. Television news favours debate that is presented by individuals as contrasting causal narratives. Political and economic sources have become adept at presenting brief causal narratives in response to the requirements of television. This approach highlights celebrities and favours the promotion of agency over structure. The increase in total economic and business reporting boosts the interdependence of television and political and economic sources. Technological development is continuing and traditional free-to-air television audiences are being eroded by pay television and the internet. Although these are altering the nature of political, economic and business debate their overall influence is difficult to determine.

Full textAbstract:
This thesis addresses the transmission of video over third generation radio access networks. The first part of the thesis investigates the capabilities of Universal Terrestrial Radio Access Networks (UTRAN) in terms of the provision of multimedia communications. The error performance and traffic requirements of real-time video transmission over circuit switched and packet switched connections are examined. The effect of network parameter settings upon video performances is evaluated, and optimum radio bearer configurations for the transmission of video are derived. A method of estimating received video quality after transmission over error prone environments is developed. The quality estimation is based on a distortion model, which accurately models the overall distortion seen in decoder frame reconstruction. This includes quantisation distortion, concealment distortion, and error propagation. Based on the developed performance model, optimum MTU (Maximum Transfer Unit) size for efficient wireless video communications over a packet switched access network is derived. The second part of the thesis investigates quality enhancement techniques for multimedia traffic transmitted over wireless channels. Quality enhancement is achieved at three levels of the transmission process: link level, application level and system level. Link level quality enhancement techniques are designed to optimise the allocation of link level parameter values according to the media characteristics. A novel Unequal Error Protection scheme and a novel Unequal Power Allocation scheme are designed to exploit the inherent diversity in the subjective importance of different sections of compressed media. The algorithms are developed and analysed for transmission of video over 3G wireless systems. The effectiveness of these algorithms is demonstrated through the results of simulated transmission over a UMTS channel. Application level quality enhancement techniques are designed to explore the time-varying nature of the wireless channel. A number of link adaptation schemes are proposed for real time video communication and real-time video streaming over 3G wireless systems. These algorithms are designed to enhance the perceptual video quality, and the system utilisation. This is achieved by adapting the allocated radio network parameters and the source parameters, according to a feedback channel condition. Simulation results show a significant performance improvement compared to non-adaptive schemes. Finally, system level adaptation techniques are designed for efficient radio resource allocation in multi-user scenarios. Two adaptive resource allocation schemes are proposed and analysed for real-time video communications in a UMTS system. The proposed algorithms are shown to provide improved performances in terms of average received video quality and user satisfaction. Key words: Wireless Communication, Multimedia communication. Video Transmission.

Full textAbstract:
Change is a prominent feature of the organizational life. Nowadays companies rely on implementing large-scale Information Technology (IT) systems in order to enhance their organizational performance. Such technochanges, similarly to planned organizational changes, unfold in stages and have an impact on the organizational members. They, however, are not immune to failures. In this respect, the process of communication has been recognized as a critical success factor and an integrative part of every change initiative. Therefore, this study has investigated the communication practices during technochange, how employees perceive them and eventually, how the communication can be enhanced in order to assure the employees’ engagement. This has been done by conducting a case study at an office of a company in Stockholm, Sweden. The study was carried out through a combination of qualitative data collection methods. The data was analyzed with a help of a theoretical framework and sorted in themes that emerged from the collected empirics. The findings indicate the process of communication has been considered and acknowledged by the case organization. The use of several communication channels for disseminating of hange information and collecting employees’ input have formed the employees’ perception of the change and communication processes. Specifically, intranet and meetings accommodate the applied one-way communication channels, while workshops and trainings represent the applied more participative communication methods. Furthermore, the study illustrates that the non-implementers are not a homogenous group and different stakeholders perceive the hange in different ways that in turn creates different communication needs. Those findings lead to identification of improvement areas and practical suggestions for implementers and managers. From a theory perspective, this thesis makes an attempt to gain deeper understanding of specific communication approaches and their effect on employees in the context of technochange.

Les progrès technologiques ont permis le développement d'applications de capteurs sans fil. Les capteurs densément distribués impliquent le plus souvent de faibles débits de données et de faibles portées de transmission. L'efficacité énergétique demeure une contrainte importante pour la conception des réseaux de capteurs sans fil. Pour ces applications, les noeuds sont généralement déployés avec des ressources énergétiques réduites et le remplacement d'une batterie peut être coûteux. Plusieurs méthodes peuvent être utilisées pour minimiser la consommation d'énergie dans ces réseaux. Dans cette thèse, nous nous concentrons sur la couche physique et sur la réduction de la consommation d'énergie des méthodes de transmission en utilisant des modulations à faible énergie. Une première étude nous permet de déduire que pour un canal BBAG, le codage à minimum d’énergie basé sur la modulation OOK est efficace énergétiquement, mais au prix d’une efficacité spectrale réduite. Seule la puissance de transmission est considérée et la consommation des circuits électroniques n’est pas prise en compte. Ensuite, des modèles de consommation d'énergie différents sont introduits afin d’obtenir une analyse de l'efficacité énergétique de transmetteurs réalistes. Le fait que le codage à minimum d’énergie améliore l'efficacité énergétique est confirmé et les limites des circuits électroniques pratiques sont mises en évidence. Enfin, le protocole réseau est abordé par l'introduction du protocole de contrôle d'erreurs ARQ. Finalement, l'efficacité énergétique d'une télécommande autonome est améliorée en utilisant la modulation orthogonale OOK et un véritable démonstrateur est présentéTechnological advances have resulted in the development of wireless sensor applications. The densely distributed sensors, generally used for data gathering, environmental monitoring, industrial automation or surveillance, involve often low data rates and low transmission ranges. Despite the progress in software and hardware technologies, the energy efficiency is still one of the important constraints for the design of Wireless Sensor Network (WSN). For wireless sensor applications, nodes are usually deployed with reduced energy resources and without capability of battery replacement. Several techniques could be used to minimize the energy consumption of WSN. In this thesis we focus the physical layer and we propose to reduce the energy consumption by using low energy coding schemes. Firstly, a study allows us to deduce that in AWGN channel, Minimum-Energy Coding based on OOK modulation is energy efficiency, but at the price of lower spectrum efficiency. Only the transmission power is considered and the consumption of electronic circuits is not taken into account. Then, different energy consumption models are introduced to achieve energy efficiency analysis using realistic devices. The fact that Minimum-Energy coding based on OOK improves the energy efficiency performance is confirmed and the limits of practical circuits are highlighted. At last, the network protocol is addressed by introducing the ARQ error control protocol. Finally, the energy efficiency of an autonomous remote control is improved by using OOK orthogonal modulation and a real demonstrator is realized

Thesis (MScEng)--Stellenbosch University, 2012.ENGLISH ABSTRACT: A low earth orbit satellite system can be useful in numerous communication applications where physical connections are not possible. Communication time available from any point on earth to the satellite is less than one hour per day. This one hour is fragmented into smaller time slots due to the satellite orbiting. This is not much time to transfer data and there is even less time available to transfer data when there are other external factors affecting the system. It is thus crucial to optimise the satellite communications link so that more data can be transferred per orbit. The goal of this thesis is to improve the performance of a low earth orbit satellite communication channel by varying certain parameters of the system, such as the protocol used, modulation scheme, packet size, transmission power etc. and then to observe how these parameters influence the system. The protocols that were chosen to be implemented are CSMA-CA, CSMA-CA with DSSS technology and Round-Robin Polling. A simulator for each protocol was designed with the Opnet platform, so that specific parameters could be changed and the results observed, in order to optimise the communications link between the satellite and ground stations. The results showed that there is no particular configuration of modulation scheme, packet size, transmission power etc. presenting the best overall solution for LEO satellite communications. It must be considered what the specific LEO satellite application would be used for and the characteristics required by that specific application. A suitable configuration must subsequently be chosen from the set of configurations available to satisfy most of the application requirements.
AFRIKAANSE OPSOMMING: ’n Satelliet met ’n lae wentelbaan kan gebruik word in verskeie kommunikasie toepassings waar fisiese verbindinge nie noodwendig moontlik is nie. Die kommunikasietyd van enige punt van aarde af na die satelliet, is minder as een uur per dag. Hierdie tyd word nog verder verklein omdat die satelliet besig is om, om die aarde te wentel. ’n Uur is glad nie baie tyd om data oor te dra nie en in realiteit is daar nog minder tyd beskikbaar as daar eksterne faktore op die sisteem inwerk. Dus is dit baie belangrik om die satelliet kommunikasiekanaal te optimiseer sodat soveel moontlik data as moontlik oorgedra kan word per omwenteling. Die doel van hierdie tesis is om die deurset van die kommunikasiekanaal van n lae wentelbaan satelliet te optimiseer, deur verskeie parameters te verander soos, protokol wat gebruik word, modulasie skema, pakkie grootte, transmissiekrag ens. en dan waar te neem hoe dit die sisteem beïnvloed. Die protokolle wat geïmplementeer is, is CSMA-CA, CSMA-CA met DSSS tegnologie en Round-Robin Polling. ’n Simulator vir elke protokol was ontwerp in die Opnet simulasie platform, sodat die spesifieke parameters verander kon word om die resultate te bestudeer met die doel om die kommunikasiekanaal tussen die satelliet en grond stasies optimaal te benut. Die resultate het bewys dat daar geen spesifieke konfigurasie van modulasie skema, pakkie grootte, transmissiekrag ens. is wat die algehele beste oplossing is nie. Die spesifieke applikasie waarvoor die lae wentelbaan satelliet gaan gebruik word moet geanaliseer word sowel as die spesifieke karakteristieke van daai applikasie. Daarvolgens moet n unieke konfigurasie opgestel word wat meeste van die applikasie se behoeftes bevredig.

Full textAbstract:
Though eating disorders are a serious public health threat, misinformation about these potentially deadly diseases is widespread. This study examines eating disorder information from a wide variety of sources including medical journals, news reports, and popular social activist authors. Examples of misinformation were identified, and three aspects of eating disorders (prevalence, mortality, and etiology) were chosen as key indicators of scientific illiteracy about those illnesses. A case study approach was then adopted to trace examples of misinformation to their original sources whenever possible. A dozen examples include best-selling books, national eating disorder information clearinghouses; the news media; documentary feature films; and a PBS television Nova documentary program. The results provide an overview of the ways in which valid information becomes flawed, including poor journalism, lack of fact-checking, plagiarism, and typographical errors. Less obvious—and perhaps even more important—much of the misinformation results from scientific research being co-opted to promote specific sociopolitical agendas. These results highlight a significant gap in science communication between researchers, the medical community, and the public regarding these diseases, and recommendations to address the problem are offered.

Full textAbstract:
This study offers insight into international audience reception of Corporate Social Responsibility (CSR) communication. Swedish companies are currently reaching international audiences through a variety of social media channels and this study analyzes how audiences in Sweden and the U.S. respond to specific messages. Qualitative interviews with professionals offer background information on how CSR is currently communicated while audience responses to CSR communication are gathered through a web-based survey and focus groups consisting of American and Swedish citizens. Results indicate that the two countries have more similarities than differences. Americans have a slightly more positive outlook on the communication and they are more likely to look up information about CSR initiatives after hearing a corporate message. This might indicate a more profound interest. Cultural and social differences are given as a possible explanation for the key differences.

Full textAbstract:
Abstract. The traditional autonomous vehicle (AV) architecture places a heavy burden on graphics processing units of the vehicle due to heavy signal processing requirements. Ultimately this results in performance degradation in AVs. This is mainly due to advanced sensors, which enable the vision for AVs, like Light Detection and Ranging (LiDAR), radars and cameras. In most of the AV models accepted by many leading automobile companies, LiDAR plays a significant role. It generates a high definition (HD) point cloud of the surroundings to obtain a precise map. AV makes decisions based on that by processing Terabyte (Tb) scale data within the AV. Still, vehicle-mounted LiDARs are not capable of providing information beyond a human driver’s vision.
To provide a solution for the above-mentioned drawbacks of the traditional AVs, we propose an infrastructure based communication architecture to facilitate autonomous driving and communications. A set of coordinated LiDAR modules with integrated transceivers, which are mounted at an elevation with a bird’s eye view, can provide a much larger field of vision (FoV). Decisions are taken from a centralized body. We prove the technical feasibility of the system from sensing and communication point of view. The proposed architecture can play a supportive role with traditional AV architectures and it can be applied to many cases such as to automate harbours and factory floors.
In the second part of the thesis, we address a resource allocation problem with ultra-reliable and low latency communication (URLLC) for a factory floor. We have analytically proven the capability of the proposed system to establish a reliable (packet error probability less than 10^(-5)) and low latency (less than 1 ms transmission delay) links with sufficient throughput (kilobit scale) using a convex optimization problem. Latency, throughput and reliability variations are studied under the short packet transmission of the proposed system.

Full textAbstract:
The objective of this thesis is to research how to use JavaScript to communicate with a legacy JMS broker, specifically OpenMQ 4.1 and implementing a proof- of-concept of this. This proof-of-concept should be able to send and receive JMS messages. The necessary preparations for designing this application was to research possible ways of communicating with different JMS brokers using oth- er languages than Java. This research showed that the only viable method in or- der to communicate with this version of OpenMQ is to create a Java bridge be- tween JavaScript and the JMS broker. The results shows that it's possible to use JavaScript to communicate with OpenMQ 4.1 by using a Java Bridge together with NodeJS. This result is performed by making an integration test, by first sending a message with a certain ID to the API and then receiving a response at the intended response destination with the same ID. The front-end of the proof- of-concept provides a web application UI for performing this integration test. Future improvements of this implementation can be done by extending the Java Bridge and API in such a way that it can be used against many different JMS brokers. The configuration data used can also be stored in more reliable ways, if multiple users are using the API and web application at the same time, for example by using a database instead of JSON files.

Full textAbstract:
This dissertation proposed and operationalized a theoretically meaningful and practically useful conceptualization of change for three well known communication constructs, namely willingness to communicate (WTC), self-perceived communication competence (SPCC), and communication apprehension (CA). Specifically, this research found that students' WTC and SPCC scores increased linearly during the semester and their CA scores decreased linearly. In addition, results from this dissertation indicated that for all three constructs considerable differences among students existed with respect to both initial levels and subsequent change in levels. These results are important and can advance the theoretical communication research centered around these constructs. In particular, knowledge that the hypothesis of linear change in the constructs received support from empirical data and that variations in students' trajectories of change were recorded, can prompt communication scholars to search for novel theoretical frameworks that can explicate these change processes. Moreover, the findings of this research are also salient for classroom instruction. Specifically, teachers of introductory communication classes can use the results of this study as broad benchmarks that can inform realistic expectations with respect to students' improvement in WTC, SPCC, and/or CA. In addition, this dissertation presented the benefits derived from properly conceptualizing and studying change by means of latent growth modeling, a powerful and versatile data analytic technique. Specifically, employing this methodology offered the opportunity to get detailed information about how changes in one construct are related to changes in the other two constructs and to gain a more in-depth knowledge of the intricate ways in which interlinkages among the constructs change across time. The benefits of this dynamic way to study WTC, SPCC, and CA are readily apparent as it facilitates teachers access to information that can be used to tailoring their activity for a more targeted, efficient, and beneficial instruction.

Full textAbstract:
The purpose in this thesis is to analyse which information about the sustainable impacts in fashion supply chain is the most important for the consumer. To find out how the eco-label can be designed with information and messages about the sustainable producing process, and to make the consumer more safe and satisfied with the fashion industry’s communication about sustainability and their sustainable products. - How to define sustainability in fashion supply chain? - What information about eco-labeled clothes does the fashion consumers require? - What are the conditions for creating and designing sustainable messages on the clothing’s eco-labels? In the final definition of sustainability according to this study, the focus falls on four distinctive expressions, which are, good working conditions, profitability, comfort and human needs. To explain this further, the good working conditions and the human needs have to do with wellbeing and health for the consumer and workers. Profitability has to do with the economy for both companies and consumers, and comfort is something both consumers and workers strive for. So the finally definition of sustainability in this thesis is to strive for better health, economy and comfort for all people. The information about eco-labeled clothes that the consumers require, have actually nothing to do with sustainability. However, the consumers require information about price, quality, and comfort. Moreover, if the product would be eco-labeled, the consumer should wish to get reliable information about the working conditions and chemicals, which gives the consumer a chance to know what they are paying for. To be able to create a message the focus should be on significances that increases the consumers self-interests, which in this case would be long lasting quality, health and price. These significances are similar to the earlier presented definition of sustainability, which is to strive for better health, economy and comfort for all people. Here comfort can be a part of the long lasting quality or a part of the good working conditions in the supply chain. Therefore, a sustainable message with reliable information about price and quality should be the symbol that explains how it affects the health, economy, and comfort for both the consumers and the employees in the fashion supply chain.

This study explores what a company, that is working with sustainability or environmental issues, knows of their customers knowledge about this topic. How can this company get their customers more involved in sustainability issues and should they get them involved at all? This study was in collaboration with Big Image System (BIG) and data was collected and reviewed regarding the company’s recent social media activities on how they communicate their sustainability work to their customers. A survey was conducted and results show that most customers are aware of sustainability work in general and that the interest in environmental issues is high. They also show that distributing more relevant information to the customers is something the customers value and are interested in getting.

This thesis explores the cultural considerations American technical communicators must address when working with French colleagues and when creating technical documentation for French audiences. A review of the literature on intercultural communication theory was conducted, along with a review of the limited research on technical communication in France and the needs of French audiences. A qualitative online survey of French technical communicators was also conducted. Through this survey, French technical communicators reported on their intercultural beliefs, experiences, and practices, and information, language, and cultural needs. Survey responses were analyzed using inductive thematic analysis. Two main themes were developed as a result of this analysis: the importance of adapting content to French audiences, and the cultural differences between French and American information needs and communication styles. Survey findings were combined with theoretical and practical literature to offer American technical communicators guidance for successful intercultural interactions. This thesis concludes with suggestions for future practice and research in intercultural technical communication.M.A.

Full textAbstract:
With a wide range of potential applications, the machine type communication (MTC) is gaining a tremendous interest among mobile network operators, system designers, MTC specialist companies, and research institutes. The idea of having electronic devices and systems automatically connected to each other without human intervention is one of the most significant objectives for future wireless communications. Low data rate transmission and the requirement for low energy consumption are two typical characteristics for MTC applications. In terms of supporting low cots MTC devices, industrial standards will be more efficient if designers can re-use many features of existing radio access technologies. This will yield a cost effective solution to support MTC in future communication systems. This thesis investigates efficient MTC waveform and receiver designs for superior signal transmission quality with low operational costs. In terms of the downlink receiver design, this thesis proposes a novel virtual carrier (VC) receiver system for MTC receivers, which aims to reduce the maximum bandwidth to improve the data processing efficiency and cost-efficiency by using analogue filters to extract only sub-carriers of interest. For the VC receiver systems, we thus reduce the sampling rate in order to reduce the number of subsequent processing operations, which significantly reduces the analogue-to-digital converter (ADC) cost and power consumption while providing high signal to interference noise ratio (SINR) and low bit to error rate (BER) to support low data rate MTC devices. Our theoretical equations account for the interference effect of aliasing on the sub-carrier location, and this helps the system designer to evaluate what kind of filters and receiver sampling rate can be used to balance the energy cost and detection performance. In terms of the uplink waveform design, considering the enhanced number of MTC devices in the future communication systems, i.e. the fifth generation (5G) communications, the same tight synchronisation as used in today appears not to be cost-effective or even possible. Synchronisation signals, which aim to provide a perfect time or frequency synchronisation in the current fourth generation (4G) communication systems (known as the long-term evolution, LTE), is much more costly for low data rate MTC transmissions. The system bandwidth will be significantly reduced if a base station tries to synchronise all received signals among hundreds or thousands MTC devices in one transmission time period. In terms of relaxing the synchronisation requirements, this thesis compares and analyses the side-lobe reduction performance for several candidate multi-carrier waveforms to avoid these problems. We also propose the infinite impulse response universal filtered multi-carrier (UFMC) system and the overlap and add UFMC system, which significantly reduce the processing complexity compared with the state of the art UFMC techniques. This thesis derives closed-form expressions for the interference caused by time offsets between adjacent unsynchronised MTC users. Our analytical equations can be used in both simple and complex time-offset transmission scenarios, and enable the system designer to evaluate the SINR, the theoretical Shannon capacity and the BER performance.

Full textAbstract:
The university classroom is an invaluable site for social activism. In this study, I focus on the university classroom in order to consider how university instructors care for students. More specifically, I consider what I call critical care--that is, care underscored by critical and critical communication pedagogy. I start by defining care, critical pedagogy, and critical communication pedagogy. Then, I focus on my own experiences autoethnographically to understand some of the ways I have come to understand care. After conducting interviews with teachers and those teachers' former students, I conducted dyad interviews between the teacher and the teacher's former student. I use the transcripts of these interviews as the data for an analysis of how these teachers and students understand care in their relationship. Because the teachers selected must have some background with critical and/or critical communication pedagogy, I also use the transcripts to build a case for critical care. I argue that critical care is the best way to build more humane and equitable classrooms.

Full textAbstract:
On 11 March 2020 the World Health Organization (WHO) proclaimed the corona outbreak to be a pandemic, and on the same day, the first Swede, a person in his upper 70s, died of Covid-19. The Covid-19 pandemic had a significant impact on school settings and affected higher education globally. Students faced sudden changes to their lives and relied upon written messages for directives. This study investigated Uppsala University in Sweden as a case study. The purpose of this study was twofold: to examine strategic communication by Uppsala University aimed at students during the Covid-19 crisis, and to investigate the way the students at the university perceived and made sense of this crisis communication. The study was conducted when the pandemic was still ongoing and specifically focused on communication and perceptions during the time of November 2020 until the end of April 2021. The study relies on the concept of sticky crises. It has further used Coomb’s Situational Crisis Communication Theory based on Attribution Theory in order to analyze crisis communication. This has been used in combination with Reception Theory in order to evaluate how students have decoded messages. This study claims Uppsala University has been using a varied crisis communication strategy. However, there has been a gap between certain messages (adjusting information) and students. This gap is due to three different reasons: the nature of the complex crisis, the decentralized institution, and because not enough messages have combined different message strategies when communicating and mostly just focused on instructing information.

Evolving communication technology, the increased volume of information needed by businesses, and the intensified competitive environment have made internal company communication more critical to business success. The purpose of this multiple case study was to explore strategies used by managers and leaders of 3 law firms in the Commonwealth of Virginia for assessing the effectiveness of their organization's internal communication channels. The participating firms were recognized by their peers as being exceptionally well-managed. Data from interviews and company documents were analyzed through the conceptual lens of the channel expansion theory and the use of software coding to identify patterns and themes. Three important themes emerged: informal assessment strategies, indirect assessment strategies, and efficient versus timely assessments. The first theme suggested the effectiveness of an informal assessment strategy, depending on the size and complexity of the organization. The second theme reflected the effectiveness of an indirect assessment for organizations that lack the resources to support a more direct and specific assessment process. The third theme reflected the participants' perceptions of informal and indirect assessments may be more efficient, the feedback from the assessments are often less timely. Managers may consider these themes in formulating communication policies. The findings of this case study may have implications for positive social and economic change. Small professional service firms, such as legal firms, provide important services to individuals, families, and businesses in their community.

Full textAbstract:
In recent years, mobile devices have become an integral part of our everyday life in various fields. The technology that powers them is used in various devices, such as smartphones, tablets, and PDAs. These devices hold extensive computation capabilities, along with advanced communication abilities, which are supported by an internet connection and diverse types of motion and location sensors. Mobile devices have changed the way people communicate with each other, for example by providing options to send instant text messages, perform live video calls with others in addition to voice conversations. These capabilities have encouraged educators to exploit mobile technology and promote new types of learning options. There are several new learning possibilities based on tools such as mobile dedicated applications, location-based learning activities, and interactive social related tasks. These new uses require adjustments to educational programs to allow support for this type of learning. The uniqueness of mobile learning, in contrast with the classic learning paradigm, is the ability to connect the learner through enhanced learning materials to the outside environment. This breaks the physical borders that exist in the traditional classroom and creates new learning possibilities, but it has its drawbacks. One of the difficulties that arise from this type of learning is the loss of contact in real time between teacher and student, especially when performing outdoor activities. The Treasure-HIT platform was conceived to create outdoor Treasure Hunt-based games, mainly for educational purposes, by introducing an authoring web platform and a supporting mobile application. The platform includes communication capabilities based on social interactions and cooperative learning with the integration of social networks, and yet real-time educator and student communication is still lacking. Adding real-time communication features provides a way to better support ongoing learning activities, and can take pressure off the learning process for the students, by providing them with a more personal experience and immediate support when needed. This thesis follows the process of addressing this concern in TreasureHIT, including the rationale, the background, the possible options and gradual development of a prototype solution to the problem under the existing Treasure-HIT infrastructure. In the thesis, the advantages of two features are explored: (1) the Realtime Group Tracking Map, which provides a way to monitor the movement and action of groups of players during game time, and (2) Instant Text Messaging service, which allows the game instructor to send custom text messages to the different game groups. The research findings indicate that the new monitoring options provide a solid tool for real-time analysis of the progress of the game and the ability to inform about various issues and solve them in real time. ii Furthermore, the instant message service feature received positive responses from the game-manager and players alike, on the grounds of major improvements to the general game flow and problem solving in real-time.

A thesis submitted in fulfilment of the requirements for the Degree of MA in Communication Science, University of Zululand, 2001.In this thesis I focus on the introduction of Electronic Cornmunication as part of an envisaged Communication Science curriculum in the Language, Literacy and Communication Learning area of the Further Education and Training band. In the course of my thesis I will show that the requisite elements of verbal and written cornmunication are dispersed throughout the Language, Literacy and Communication learning area in the General Education and Training band, and that they can be utilised as basis for formally introducing Communication Science, as a subject in the Language, literacy and Communication learning area in the Further Education and Train¬ing band. I also show that electronic communication will form a crucial area of study in such a Communication Science curriculum. I argue that due to the diversity of cultures in South Africa, cross-cultural cornmunication is required in such a curriculum. I also argue that by the very na¬ture of Outcomes-Based Education it is necessary to have a subject into our school curriculum that will form an interface with conceptual learning and experiential learning, that will contextu-alise language study within the more comprehensive scope of forms of human communication, and that will form an interface between the humanities and science to prevent the humanities from becoming soft options in Further Education and Training band learning programmes. To this effect I focus on the crucial role of Constructivism as integrating theory to account for vari¬ous approaches to motivational learning, the primary form of learning required in Outcomes-Based Education. I examine the principles of curriculum construction in OBE and its associated culture of learn¬ing against the backdrop of the theory of Situated Cognition. This presents a platform to argue the case for Electronic Communication as part of Communication Science in the Further Edu¬cation and Training band curricula in South African schools.

Full textAbstract:
The field of augmentative and alternative communication (AAC) has evolved since the 1970s, consequently there now exists a group of adults with cerebral palsy (CP), in the UK, who are life-time users of AAC prescribed as an intervention for their complex communication impairments. Ten adults, aged between 20-55 years, participated in conversations about their unique life experiences and aspirations, using AAC, including voice output communication aids (VOCAs). The ability and opportunity to interact and communicate personal accounts has significance for conceptualizing outcomes of intervention. Clinical practice informed this research project. A qualitative research design was employed to explore questions about the extent to which adult aided communicators talk about their lives, aspirations and opinions; the past life experiences participants talk about and finally how they talk about their quality of life. Conversational-styled, semi-structured interviewing using literature-guided questions yielded rich interactional data. A discourse analytical approach to the 34 interviews was taken. Findings identified a number of ordinary interactional features and discourses. Aided communicators used multimodal communication to interact and converse, positioning through their contributions as assertive speakers and engaged recipients. Interactional turns were managed with participants using unaided communication signals as conversational continuers. Participants demonstrated how to manage others who speak on their behalf. Examples of interactional repair were noted when participants pre-empted breakdown. Managing novel utterances was a feature with unexpected responses challenging the listener’s position. Participants constructed VOCA-mediated utterances to share long-term memories, worries, satisfaction with life, and aspirations. Aspirations included community ambitions and creating fulfilling daily lives. Some participants expressed frustration but balanced this against a position of contentment. Some participants also demonstrated personal responsibility and positioned themselves through their talk as contributors to communities. Recommendations for clinical practice are suggested that include the provision of adult clinical services and interaction focused intervention for adult aided communicators with cerebral palsy.
