    Towards a Unified Framework for Media Capacity Characterization: Inferences from Critical Analysis of Media Capacity Theories, Buzzwords and Web History

    Get PDF
    As the Web enters its third decade of existence, I draw attention to the need to better understand the Web as a potential reference case for how an information system transforms through incremental innovations, with particular focus on the Web’s advancement as a communication media platform. As a necessary research step in this quest, I critically examine whether one can use existing media capacity theories and media-related buzzwords (such as rich media, multimedia, hypermedia, social media) to characterize Web innovations as media. I examine and clarify these buzzwords’ origins, meanings, and relationship with media capacity theories. I also elucidate discrepancies between them. Via inductive reasoning, I synthesize three media capacity dimensions (sensibility support, interactivity support and logistical support) as potential framework for objective media characterization. Each dimension could metamorphize into individual theories or one theory (e.g., sensibility interactivity and logistical support theory (SILST)). I present these dimensions’ indicators and demonstrate three-dimensional typology of Web innovation milestones anchored on the three dimensions—a step forward in substantiating the framework’s applicability to media capacity characterization

    The appearance of web and online media has created a substantial change in the manner by which employers and applicants interact. The development of web 1.0 applications with one-way communication and the advancement of web 2.0 technologies with interactive components have extended the spectrum of recruitment channels. The new recruitment media channels have led the selection and analysis of their impact out of interaction on each other to a new challenge within academical literature. This dissertation addresses these issues in three separate essays. Study 1 focuses on the impact of Facebook as a social media recruitment channel on recruitment success. Many companies embed Facebook into their recruitment strategy as an additional recruitment channel for reaching potential applicants and motivating them to apply for available positions. Study 1 analyzes these activities and addresses the question of whether different Facebook activities influence recruitment success above and beyond other undertakings on traditional and online media channels. Study 1 concludes that on Facebook, company posts with a general focus and posts containing work or recruitment information both have a positive impact on recruitment success. The results of Study 1 are validated by company interviews with human resources (HR) managers who are responsible for the overall HR strategy of the company. Study 1 is the first academic work within HR and marketing research, which analyzes the impact of a company’s Facebook activities. Study 2 examines the impact of traditional media recruitment channels on recruitment success. Many companies employ traditional media channels for their recruitment marketing actions with the aim of achieving recruitment success. Study 2 uses media richness theory as a basis for analyzing the impact of a company’s activities within traditional media channels on recruitment success. Study 2 concludes that exhibition fair and online marketing activities influence recruitment success. In connection with brand equity theory, Study 2 also verifies whether the addition of Facebook activities reinforces the impact of traditional media channels on recruitment success. The results indicate that general Facebook activities have a reinforcing impact on exhibition fair and print media recruitment practices. Finally, Study 3 focuses on both the literature overview of traditional and social media recruitment practices and social media influence from the marketing literature. It also summarizes and categorizes previous research on the influence of traditional, online, and social media recruitment practices; the effect of a multichannel mix; and the influence of social media and social networking sites on different business outcomes from the marketing literature. Additionally, Study 3 identifies the research gaps and provides recommendations for future studies. This dissertation uses vector autoregression modelling, including a validation with the help of company interviews and the employment of media richness, signaling, and brand equity theories, combined with a thorough analysis of the research need. The dissertation closes the research gap regarding the analysis of the impact of Facebook, online, and traditional media on recruitment success. It also adds new perspectives to the HR and marketing literature

    The Hierarchic treatment of marine ecological information from spatial networks of benthic platforms

    Get PDF
    Measuring biodiversity simultaneously in different locations, at different temporal scales, and over wide spatial scales is of strategic importance for the improvement of our understanding of the functioning of marine ecosystems and for the conservation of their biodiversity. Monitoring networks of cabled observatories, along with other docked autonomous systems (e.g., Remotely Operated Vehicles [ROVs], Autonomous Underwater Vehicles [AUVs], and crawlers), are being conceived and established at a spatial scale capable of tracking energy fluxes across benthic and pelagic compartments, as well as across geographic ecotones. At the same time, optoacoustic imaging is sustaining an unprecedented expansion in marine ecological monitoring, enabling the acquisition of new biological and environmental data at an appropriate spatiotemporal scale. At this stage, one of the main problems for an effective application of these technologies is the processing, storage, and treatment of the acquired complex ecological information. Here, we provide a conceptual overview on the technological developments in the multiparametric generation, storage, and automated hierarchic treatment of biological and environmental information required to capture the spatiotemporal complexity of a marine ecosystem. In doing so, we present a pipeline of ecological data acquisition and processing in different steps and prone to automation. We also give an example of population biomass, community richness and biodiversity data computation (as indicators for ecosystem functionality) with an Internet Operated Vehicle (a mobile crawler). Finally, we discuss the software requirements for that automated data processing at the level of cyber-infrastructures with sensor calibration and control, data banking, and ingestion into large data portals.Peer ReviewedPostprint (published version

    Students’ Acceptance On Educational Video Sharing Sit: A Proposed Research Model

    Get PDF
    Video sharing site is becoming increasingly popular and is used as a platform for video-based learning and teaching. In line with the development of new media technologies nowadays, learning through video sharing sites has become a choice of preference amongst students to get access to learning materials in the form of videos such as screencast tutorials, video presentations, recordings of learning video, animations and so forth. However, the existence of video sharing sites that have a social media characteristic in them is negatively affecting the students' learning performance. Thus, a provision of video sharing site with a more formal educational characteristic should be established in order to facilitate a safer learning environment. This study was conducted to analyse the acceptance of students towards educational video sharing sites. By using Technology Acceptance Model (TAM) as the basic model for this study, the original attributes in TAM model such as perceived usefulness and perceived ease of use were put to the test in order to determine their effects on attitudes and intentions of the students to use educational video sharing sites. In addition to that, TAM model was also expanded by adding other factors such as psychological factors (enjoyment and motivation), social factors (social influence and subjective norm), technological factors (system performance and system accessibility) and organisational factors (facilitating condition and technical support). This conceptual paper was prepared to tested on how they affect students' acceptance towards educational video sharing sit

    CHORUS Deliverable 2.2: Second report - identification of multi-disciplinary key issues for gap analysis toward EU multimedia search engines roadmap

    After addressing the state-of-the-art during the first year of Chorus and establishing the existing landscape in multimedia search engines, we have identified and analyzed gaps within European research effort during our second year. In this period we focused on three directions, notably technological issues, user-centred issues and use-cases and socio- economic and legal aspects. These were assessed by two central studies: firstly, a concerted vision of functional breakdown of generic multimedia search engine, and secondly, a representative use-cases descriptions with the related discussion on requirement for technological challenges. Both studies have been carried out in cooperation and consultation with the community at large through EC concertation meetings (multimedia search engines cluster), several meetings with our Think-Tank, presentations in international conferences, and surveys addressed to EU projects coordinators as well as National initiatives coordinators. Based on the obtained feedback we identified two types of gaps, namely core technological gaps that involve research challenges, and “enablers”, which are not necessarily technical research challenges, but have impact on innovation progress. New socio-economic trends are presented as well as emerging legal challenges

    There has been rapid adoption of social media (SM) in business functions such as marketing and advertising. This being primarily due to its capability to communicate information. There has been less widespread adoption of SM for other business functions and the potential of SM is not comprehensively understood. The purpose of this thesis is to explore the potential of SM for project management and to understand some of the difficulties that arise from SM use. The research specifically investigated how SM is being used for project activities and the maturity of the management processes that govern SM use. Implications for underlying theories such as virtual team, social capital and process maturity have also been analysed. An expert panel of project management practitioners from various geographic regions were invited to participate in this research. To facilitate the investigation, the Project Management Body of Knowledge (PMBOK) from Project Management Institute (PMI) was used as the term of reference comprising forty seven project management activities. The research utilised two methods, firstly a Delphi Study of three rounds was used to identify the fundamentals of the phenomenon and attempt to align the expert views, and secondly, Structured Case Study interviews took place to explore the rationale and motivation of responses given by selected panellists. It further investigates the impact on project team performance and the robustness of processes that supports SM use by assessing the contribution to relationship building, trusts, coordination, cohesion and team virtuality. Key findings from the Delphi Study indicate that not all SM categories offer benefit for project activities. A list of SM categories that are most and least useful for all forty seven PMBOK process activities (across the project lifecycle) was identified. The two knowledge areas that are significantly benefitted are communication and stakeholder management while procurement management had limited use for SM. The findings also led to factors that could enable and inhibit the use of SM. Structured Case study confirmed that project team performance is enhanced through the use of SM as it improves social capital factors of relationship building, coordination and cohesion, however, trust development is not easily achieved. SM tools support mobility, facilitate effective and efficient information sharing, provide a single information repository and offer wider stakeholder reach surpassing geographic limitations constrained only by internet connectivity which in composite results in cost savings for project team communication. These factors increase team virtuality but the perception that SM use is free or of minimal costs, may encourage circumvention of control mechanisms such as senior management reviews and approvals. Findings indicate that lack of formulated business processes to manage SM use will lead to poor governance. Therefore, a Social Media Maturity Model (SM Cube hereafter) was propagated. SM Cube will help project professionals evaluate the robustness of SM enabling processes. This research proffers a mechanism to determine maturity of support processes for SM use thereby adding originality to the body of knowledge. Project professional can use this research as a guideline or framework to introduce SM for their project management. It extends the process maturity, virtual team and social capital theories

    Semantic discovery and reuse of business process patterns

    Get PDF
    Patterns currently play an important role in modern information systems (IS) development and their use has mainly been restricted to the design and implementation phases of the development lifecycle. Given the increasing significance of business modelling in IS development, patterns have the potential of providing a viable solution for promoting reusability of recurrent generalized models in the very early stages of development. As a statement of research-in-progress this paper focuses on business process patterns and proposes an initial methodological framework for the discovery and reuse of business process patterns within the IS development lifecycle. The framework borrows ideas from the domain engineering literature and proposes the use of semantics to drive both the discovery of patterns as well as their reuse
