An argument for using participatory approaches for the design of online health interventions targeted at young women

The Internet is becoming an increasingly important portal to health information and means for promoting health in user populations. As the most frequent users of online health information, young women are an important target population for e-health promotion interventions. Health-related websites have traditionally been generic in design, resulting in poor user engagement and affecting limited impacts on health behaviour change. Mounting evidence suggests that the most effective health promotion communication strategies are collaborative in nature, fully engaging target users throughout the development process. Participatory design approaches to interface development enable researchers to better identify the needs and expectations of users, thus increasing user engagement in, and promoting behaviour change via, online health interventions. This article introduces participatory design methods applicable to online health intervention design and presents an argument for the use of such methods in the development of e-Health applications targeted at young women.

A socio-economic approach to online vision graph generation and handover in distributed smart camera networks

In this paper we propose an approach based on self-interested autonomous cameras, which exchange responsibility for tracking objects in a market mechanism, in order to maximise their own utility. A novel ant-colony inspired mechanism is used to grow the vision graph during runtime, which may then be used to optimise communication between cameras. The key benefits of our completely decentralised approach are on the one hand generating the vision graph online which permits the addition and removal cameras to the network during runtime and on the other hand relying only on local information, increasing the robustness of the system. Since our market-based approach does not rely on a priori topology information, the need for any multi-camera calibration can be avoided. © 2011 IEEE.

Exploring the adoption of interactive digital television services as a retail shopping platform

The aim of this research is to consider the possible effect of an emerging technology platform on the uptake of online shopping: interactive (digital) Television (iTV), which enables viewers to select a variety of viewing options, publicity materials, games, entertainment and more recently shopping. An augmented version of the original TAM is applied to this study. Two new constructs are considered namely access and awareness together with perceived ease of use, perceived usefulness, perceived enjoyment and security. The results show that indeed the augmented TAM can be used as a predictive model for the adoption of iTV as an online shopping platform. It is concluded that access, perceived ease of use, perceived enjoyment and perceived usefulness are significant factors to determine the consumers’behavioural intentions towards the use of digital TV as a new shopping platform. However, awareness and security are considered to be insignificant with no effect on consumers’ behavioural intentions towards the new shopping medium.

Online trendy topics detection in microblogs with selective user monitoring under cost constraints

As microblog services such as Twitter become a fast and convenient communication approach, identification of trendy topics in microblog services has great academic and business value. However detecting trendy topics is very challenging due to huge number of users and short-text posts in microblog diffusion networks. In this paper we introduce a trendy topics detection system under computation and communication resource constraints. In stark contrast to retrieving and processing the whole microblog contents, we develop an idea of selecting a small set of microblog users and processing their posts to achieve an overall acceptable trendy topic coverage, without exceeding resource budget for detection. We formulate the selection operation of these subset users as mixed-integer optimization problems, and develop heuristic algorithms to compute their approximate solutions. The proposed system is evaluated with real-time test data retrieved from Sina Weibo, the dominant microblog service provider in China. It's shown that by monitoring 500 out of 1.6 million microblog users and tracking their microposts (about 15,000 daily) with our system, nearly 65% trendy topics can be detected, while on average 5 hours earlier before they appear in Sina Weibo official trends.

Adaptive resource allocation for QoE-aware mobile communication networks

A real-time adaptive resource allocation algorithm considering the end user's Quality of Experience (QoE) in the context of video streaming service is presented in this work. An objective no-reference quality metric, namely Pause Intensity (PI), is used to control the priority of resource allocation to users during the scheduling process. An online adjustment has been introduced to adaptively set the scheduler's parameter and maintain a desired trade-off between fairness and efficiency. The correlation between the data rates (i.e. video code rates) demanded by users and the data rates allocated by the scheduler is taken into account as well. The final allocated rates are determined based on the channel status, the distribution of PI values among users, and the scheduling policy adopted. Furthermore, since the user's capability varies as the environment conditions change, the rate adaptation mechanism for video streaming is considered and its interaction with the scheduling process under the same PI metric is studied. The feasibility of implementing this algorithm is examined and the result is compared with the most commonly existing scheduling methods.

The governance of online expression in a networked world:free-speech, surveillance and censorship

In recent years, we have witnessed the mushrooming of pro- democracy and protest movements not only in the Arab world, but also within Europe and the Americas. Such movements have ranged from popular upheavals, like in Tunisia and Egypt, to the organization of large- scale demonstrations against unpopular policies, as in Spain, Greece and Poland. What connects these different events are not only their democratic aspirations, but also their innovative forms of communication and organization through online means, which are sometimes considered to be outside of the State’s control. At the same time, however, it has become more and more apparent that countries are attempting to increase their understanding of, and control over, their citizens’ actions in the digital sphere. This involves striving to develop surveillance instruments, control mechanisms and processes engineered to dominate the digital public sphere, which necessitates the assistance and support of private actors such as Internet intermediaries. Examples include the growing use of Internet surveillance technology with which online data traffic is analysed, and the extensive monitoring of social networks. Despite increased media attention, academic debate on the ambivalence of these technologies, mechanisms and techniques remains relatively limited, as is discussion of the involvement of corporate actors. The purpose of this edited volume is to reflect on how Internet-related technologies, mechanisms and techniques may be used as a means to enable expression, but also to restrict speech, manipulate public debate and govern global populaces.

Quality-driven resource utilization methods for video streaming in wireless communication networks

This research is focused on the optimisation of resource utilisation in wireless mobile networks with the consideration of the users’ experienced quality of video streaming services. The study specifically considers the new generation of mobile communication networks, i.e. 4G-LTE, as the main research context. The background study provides an overview of the main properties of the relevant technologies investigated. These include video streaming protocols and networks, video service quality assessment methods, the infrastructure and related functionalities of LTE, and resource allocation algorithms in mobile communication systems. A mathematical model based on an objective and no-reference quality assessment metric for video streaming, namely Pause Intensity, is developed in this work for the evaluation of the continuity of streaming services. The analytical model is verified by extensive simulation and subjective testing on the joint impairment effects of the pause duration and pause frequency. Various types of the video contents and different levels of the impairments have been used in the process of validation tests. It has been shown that Pause Intensity is closely correlated with the subjective quality measurement in terms of the Mean Opinion Score and this correlation property is content independent. Based on the Pause Intensity metric, an optimised resource allocation approach is proposed for the given user requirements, communication system specifications and network performances. This approach concerns both system efficiency and fairness when establishing appropriate resource allocation algorithms, together with the consideration of the correlation between the required and allocated data rates per user. Pause Intensity plays a key role here, representing the required level of Quality of Experience (QoE) to ensure the best balance between system efficiency and fairness. The 3GPP Long Term Evolution (LTE) system is used as the main application environment where the proposed research framework is examined and the results are compared with existing scheduling methods on the achievable fairness, efficiency and correlation. Adaptive video streaming technologies are also investigated and combined with our initiatives on determining the distribution of QoE performance across the network. The resulting scheduling process is controlled through the prioritization of users by considering their perceived quality for the services received. Meanwhile, a trade-off between fairness and efficiency is maintained through an online adjustment of the scheduler’s parameters. Furthermore, Pause Intensity is applied to act as a regulator to realise the rate adaptation function during the end user’s playback of the adaptive streaming service. The adaptive rates under various channel conditions and the shape of the QoE distribution amongst the users for different scheduling policies have been demonstrated in the context of LTE. Finally, the work for interworking between mobile communication system at the macro-cell level and the different deployments of WiFi technologies throughout the macro-cell is presented. A QoEdriven approach is proposed to analyse the offloading mechanism of the user’s data (e.g. video traffic) while the new rate distribution algorithm reshapes the network capacity across the macrocell. The scheduling policy derived is used to regulate the performance of the resource allocation across the fair-efficient spectrum. The associated offloading mechanism can properly control the number of the users within the coverages of the macro-cell base station and each of the WiFi access points involved. The performance of the non-seamless and user-controlled mobile traffic offloading (through the mobile WiFi devices) has been evaluated and compared with that of the standard operator-controlled WiFi hotspots.

Direct sequence spread spectrum based PWM strategy for harmonic reduction and communication

Switched mode power supplies (SMPSs) are essential components in many applications, and electromagnetic interference is an important consideration in the SMPS design. Spread spectrum based PWM strategies have been used in SMPS designs to reduce the switching harmonics. This paper proposes a novel method to integrate a communication function into spread spectrum based PWM strategy without extra hardware costs. Direct sequence spread spectrum (DSSS) and phase shift keying (PSK) data modulation are employed to the PWM of the SMPS, so that it has reduced switching harmonics and the input and output power line voltage ripples contain data. A data demodulation algorithm has been developed for receivers, and code division multiple access (CDMA) concept is employed as communication method for a system with multiple SMPSs. The proposed method has been implemented in both Buck and Boost converters. The experimental results validated the proposed DSSS based PWM strategy for both harmonic reduction and communication.

A többcsatornás értékesítési rendszerek kihívásai - az online értékesítési csatorna integrálásának lehetőségei

Az online marketingről sokan elsősorban az interneten fellelhető új kommunikációs eszközökre asszociálnak, ugyanakkor elfeledkeznek arról, hogy az új médium mind az árazás, mind értékesítési csatornapolitika területén számos új lehetőséget, és egyben kihívást is jelent a vállalatok számára. Online környezetben egészen más fogyasztói magatartásmintákat követhetnek a potenciális ügyfelek, vásárlók, amely eltérő megközelítéseket igényelnek a cégek részéről. Kérdés azonban, hogy a sok különbözőség ellenére lehetséges-e az új csatorna integrációja az eddig működtetett értékesítési csatornákkal, egyáltalán kell-e integrálni? Az tanulmány megkísérli bemutatni azokat a stratégiai irányokat, amelyeket a többcsatornás értékesítési rendszereket működtető vállalatok követhetnek, és azonosítani az ezekkel együtt járó problémákat. / === / Online marketing is widely viewed as a new communication tool on the internet, and many times it is neglected that this channel provides a range of opportunities and, at the same time, challenges regarding pricing and sales for companies. In the online environment consumers can show quite different behaviour patterns from the ones in the offline context and it can require different approach from companies. The diverse characteristics of the internet, however, raise the question if it is possible to integrate the new channel with the existing ones? Moreover, is it necessary at all? The paper attempts to determine and present the possible strategic directions that a company can follow when applying multi-channel marketing, and identify the barriers to implement them successfully.

Az információterjedés szerepe az innováció-elfogadásban. Az okostelefonok és az on-line kollektív intelligencia (Role of informationspread in the innovation acceptance: the smart phones and the online collective intelligence)

A tanulmány célja az innováció-terjedés marketingvonzatú irodalmának bemutatása, valamint betekintés az exploratív tartalomelemzés módszerével az informális, kollektív intelligenciát generáló on-line felületek, nevesül a blogok és fórumok kutathatóságába. Az okostelefonok innováció-elfogadásának példáján keresztül a szerzők megpróbálják felderíteni az információterjedés elméletének megvalósulását az elemzett felületeken. Bemutatnak három, a mintára jellemző információterjedési és felvett szerep mintát, melyek alapul szolgálhatnak a további célirányú kutatások számára. / === / Adaptive smart phones that give space for user-added functions create active online discussions. Committed users are ready to share information, advise others, while less expert users seek this information. In their paper the authors show that related user-generated content i.e. blogs and bulletin boards provide a rich data source for analysis, which gives them the opportunity to further elaborate on the diffusion of information in the case of smart phone usage among online Hungarian users. Online collective intelligence may well contribute to the diffusion of innovations through diffusing information. Following a thorough review on the literature on the diffusion of innovations, in their exploratory content analysis, they found two categories of users on the analyzed boards: a first group we dubbed "experts" (corresponding to innovators in Bass's typology) that made a special effort trying to solve particular problems thus contributing to collective intelligence, thus reducing (among others) the perceived complexity of these phones and adding to their trialability, both factors influencing users' innovation acceptance, and a second group, "simple users" (or imitators in Bass's typology), uninterested in product innovation, still asking questions and searching for solutions concerning extant technology. Manufacturers do not seem yet to regard these boards as a source of valuable data, even though these clearly serve as an important pool of information and a growing factor of decision for their potential customers.

Az e-businesstől az online reklámozásig a versenyképesség tükrében

A „Versenyben a világgal” c. kutatási program 2009-es adatfelvételének két fő aspektusát vizsgálja a tanulmány. Az egyik az e-business / elektronikus kereskedelem területe, a másik a marketing, azon belül is online megoldások területe. Az infokommunikációs technológiák alkalmazása teszi lehetővé a vállalatok számára, hogy online jelenlétükkel és aktivitásukkal hatékonyabbá vagy épp sikeressé tegyék működésüket. Dolgozatunkban azt vizsgáljuk, hogy az egyes iparágak milyen mértékben használják az online marketing és az elektronikus kereskedelem eszközeit. Úgy véljük, hogy fontos hozadéka tanulmányunknak a két terület kérdéskörének kritikája és újrastrukturálására tett javaslatunk a kérdőív szintjén. A kutatásunk eredményei alapján elmondhatjuk, hogy a hazai vállalatok többsége használ valamilyen csatornát vagy eszközt működése során, de az eszközök megoszlása korántsem egyenletes. Míg egyes iparágak változatos megoldásokat használnak, mások szerényebb eszközkészlettel dolgoznak. Megállapításainkat ugyanakkor óvatosan kell kezelni, mivel a mintában a termelő vállalatok felülreprezentáltak voltak, elsősorban a kereskedő és különféle szolgáltató ágazatok rovására. Kvalitatív interjú segítségével vizsgáltunk két vállalatot, hogy megértsük az egyes eszközök (akár online marketing, akár e-kereskedelmi) használata és kerülése mögött álló lehetséges okokat. ________ In our study, we explore two aspects of the program titled „Competing with the world”, conducted in 2009. The field of e-business / e-commerce and online marketing is addressed. Application of info communication technologies through online presence make companies capable of a more competitive and more effective functioning. We examine the extent of use of online marketing and e-commerce tools in various industries. We believe that our critical approach and recommendations based on the structure and textual form is an important increment of our study in the reform and amendment of future research questionnaire. Based on our research, we might pronounce that majority of Hungarian companies use some kind of online channel or tool, however, distribution is not uniform. Some industries work with richer, more diverse tool sets; others use only a single channel or tool. However, we must be careful with our statement, due to the composition of the sample: manufacturing companies were overrepresented in the sample at the expense of commercial and different supplier industries. We examined two different companies through qualitative interviews to understand the reasons behind the use or avoidance of different tools (online marketing and e-business as well).

Online vs. Offline Gossip as a Source of Corporate Communicative Advantage

In a world that may be described by information revolution, it is becoming more and more important to discover the diffusion of information and news in a new technological environment. We are not dependent but, more in control of receiving and forwarding information in this technology driven environment. What we can find is that in today’s interpersonal communications, even corporate communications, gossip-like information gain a more important role. Starting from the psychological notion of gossip we asked the question how gossip occurs, evolves and disperses on the internet, what the main criteria of its diffusion and how these maybe taken into service of a company. The power of gossip derives from its biological basis that is communication advantage. The “newsmonger” maybe described with good memory, being up-to-date even in non-gossip like situations. The spread of info is faster and more precise among people with similar professions or of common interest. The content of the gossip adopts to the intellectual level of its audience. We conducted multiple research methods in order to discover about the nature of gossip of corporate interest: content analyses of blogs (N=10) and forums (N=10); online in-depth interviews (N=10); and individual consumer narratives (N=100). Our research shows that companies may lead and use gossip in an online context for their own communication intentions, however, corporate presence in terms of online gossips has to fulfill requirements in order to remain acceptable: that are specific language and place, openness, being direct about expressing intention and origin. In our paper we are going to present our major results and theoretical model

A hatásosság és hatékonyság fogalmainak értelmezése online vs. offline kampányok keretében

Az online marketing erősödése következtében a vállalatok a marketing költségvetésük egyre nagyobb arányát költik el erre a területre és ezzel párhuzamosan megnövekedett az igény az új eszközök hatásának mérésére is. A technikai adottságokból adódóan ugyanakkor az offline környezetben kialakított és alkalmazott mérési eljárások, illetve mutatók nem alkalmazhatóak egy az egyben az offline kampányok mérése során. A tanulmány célja, hogy az online és az offline kampányok esetében megvizsgálja és összehasonlítsa a hatékonyság és a hatásosság mérésének az elméleti megközelítésből, illetve a gyakorlati alkalmazásból eredő különbségeit. A kutatás rámutat azokra a lehetséges mérési eljárásokra, mutatórendszerre, amelyek lehetővé teszik a két csatornán elért teljesítmény integrált vizsgálatát.

The Attributes of Social Media as a Strategic Marketing Communication Tool

New digital trends are transforming the media industry landscape, modifying elemental characteristics and attitudes of companies as well as of consumers. Firms often claim that their presence in social media (SM) is a key element to success. SM helps companies rethink the traditional one-way flow of their marketing messages and to incorporate a new interactive pattern into their communications. Nevertheless, these tendencies involve problems of strategic myopia for firms that do not structurally integrate these tools. One main problem is that institutions can rarely differentiate between the various types of SM and the attributes thereof, while the literature equally reveals a number of contradictions in the subject. The present conceptual paper lays the foundations of a strategic approach to SM and discusses its theoretical implications. Following an overview on the concept of SM, through a content analysis of the specialized management literature (n = 14), we present various best practices and reflect on the apparent lack of strategic thinking in using SM as a marketing application. Then, we compare these practical examples with general marketing strategy theory. By merging theory and practice, we aim to provide an insight towards a well-founded application of SM as a genuinely strategic marketing tool.

"Lájk első látásra?" – Mi inspirálja a márkák kedvelését az online térben, kis vendéglátóhelyek esetében? ("Like at first sight?" – What inspires liking brands in online social media in the case of small catering establishments?)

A márkatulajdonosok számára elsődleges fontosságú, hogy feltérképezzék saját márkaközösségüket, ezáltal is elősegítve a közösségi fókuszú kommunikációs tevékenységüket. Különösen igaz ez a jellemzően kis- és középvállalati formában működő vendéglátóhelyek számára, ahol a közösségi média sokszor az egyetlen rendelkezésre álló marketingkommunikációs eszköz. Empirikus kutatásunkban fogyasztói narratívákat (n=151) elemzünk a tartalomelemzés módszertanával. A válaszadókat arra kértük, hogy írjanak kedvenc vendéglátóhelyükkel való kapcsolatukról az online térben. Elemzésünkben arra keressük a választ, hogy a márkaközösségek tagjai milyen belső indíttatásból kerültek kapcsolatba kedvenc vendéglátóhelyeikkel a közösségi platformokon. Az elsősorban fogyasztási élményekhez kötött kapcsolat online közösségi térbe való kiterjesztésére olyan belső motivációkat tártunk fel, mint a pragmatikusabb információközpontú indíttatások (pl. kizárólagos információk, naprakészség, vállalati ajánlatok, közösségimédia-specifikus tartalmakhoz való hozzáférés igénye), az érzelmi kötődés kifejezése (pl. nosztalgia, ismerősöknek való ajánlás, személyes érintettség), a társas befolyás (oldalak kedvelése mint kommunikációs tartalom, konformitás, önkifejezés), valamint a vállalati alapképességeken túlmutató egyéb tematikus kapcsolódások. ____ It is of primary importance for brand owners to map their own brand community, in order to stimulate their social-focused communication activity. This is especially true for typically small and medium-sized catering enterprises, where in most cases, social media is the only available marketing communications tool. In our empirical research, we analyze consumer narratives (n=151) with the methodology of content analysis. We asked the respondents to write about their relationship with their most preferred catering establishments in the online social sphere. In our research, we search for the inner intention by which members of brand communities got connected with their most preferred catering establishments on social platforms. We revealed such inner motivations for users extending a primarily experience (an consumption) based relationship to the online social sphere like rather pragmatic, information-focused intentions (e.g. exclusive information, timeliness, company offers, access claim for social media -specific contents), the expression of emotional binding (e.g. nostalgia, reference for acquaintances, personal involvement), social influence (the like as communication content, conformity, self-expression), and other thematic linkages beyond core company competences.
