Adapted Content Delivery for Different Contexts

International audienceIn this paper, we present a framework which allows adapted content delivery for different target contexts. This framework is based on a Universal Profiling Schema UPS for describing the environment characteristics and on an profile exchange protocol. In the server and the proxy side, we give a strategy for matching the different constraints (clients, servers, content, etc.) in order to find an agreement between the server adaptation capabilities and the client preferences and constraints. Usually such environments are subject to frequent changes. To tackle this difficulty, we propose a dynamic adaptation approach based on XSLT for structural transformation and resource aware transcoders for the media adaptation

Swarm-based Intelligent Routing (SIR) - a new approach for efficient routing in content centric delay tolerant networks

This paper introduces Swarm-based Intelligent Routing (SIR), a swarm intelligence based approach used for routing content in content centric Pocket Switched Networks. We first formalize the notion of optimal path in DTN, then introduce a swarm intelligence based routing protocol adapted to content centric DTN that use a publish/subscribe communication paradigm. The protocol works in a fully decentralized way in which nodes do not have any knowledge about the global topology. Nodes, via opportunistic contacts, update utility functions which synthesizes their spatio-temporal proximity from the content subscribers. This individual behavior applied by each node leads to the collective formation of gradient fields between content subscribers and content providers. Therefore, content routing simply sums up to follow the steepest slope along these gradient fields to reach subscribers who are located at the minima of the field. Via real traces analysis and simulation, we demonstrate the existence and relevance of such gradient field and show routing performance improvements when compared to classical routing protocols previously defined for information routing in DTN

Pervasive intelligent routing in content centric delay tolerant networks

This paper introduces a Swarm-Intelligence based Routing protocol (SIR) that aims to efficiently route information in content centric Delay Tolerant Networks (CCDTN) also dubbed pocket switched networks. First, this paper formalizes the notion of optimal path in CCDTN and introduces an original and efficient algorithm to process these paths in dynamic graphs. The properties and some invariant features of these optimal paths are analyzed and derived from several real traces. Then, this paper shows how optimal path in CCDTN can be found and used from a fully distributed swarm-intelligence based approach of which the global intelligent behavior (i.e. shortest path discovery and use) emerges from simple peer to peer interactions applied during opportunistic contacts. This leads to the definition of the SIR routing protocol of which the consistency, efficiency and performances are demonstrated from intensive representative simulations

HRM in Service: The Contingencies Abound

[Excerpt] Despite the rapid growth in the diversity of service consumers—both abroad and domestically—theoretical developments regarding this diversity in the service world have lagged far behind those that have characterized the world of manufacturing. With regard to international services, Knight (1999) conducted a review of the literature and concluded that there is an alarming paucity of research on international services management despite the importance of services in the global economy. A large proportion of the research that has been conducted on international services has focused on marketing issues rather than human resource management (HRM) issues. This means that little is known about the cross-cultural applicability of service HRM theories, which have hitherto been developed and tested almost exclusively within the West (mostly within the U.S. context). Similarly, there has been little research on the HRM implications of the growing diversity of service consumers within the U.S. domestic market. Again, much of the research focuses on the challenges associated with simultaneously marketing services to a multicultural customer base, with little or no work focusing on the implications of these challenges for HRM in service firms. Thus, the purpose of our chapter is to introduce a preliminary discussion of the HRM implications of both increased internationalization and domestic diversity for service firms. We begin by presenting a brief synthesis of the services management literature that has been established to date. Readers will note in the synthesis that a number of contingencies with regard to HRM practices have already been introduced especially via definitions of what constitutes service and the role of customers in service production and delivery. We then discuss the potential cross-cultural applicability of these services management principles abroad, and when doing so, we focus primarily on the aspects of services management theories that are laden with Western cultural principles. Next, we discuss parallel challenges faced by service firms as a result of increased diversity within the domestic marketplace and we conclude with some thoughts about the necessity to more explicitly explore the contingent nature of HRM practices

NoTube – making TV a medium for personalized interaction

In this paper, we introduce NoTube’s vision on deploying semantics in interactive TV context in order to contextualize distributed applications and lift them to a new level of service that provides context-dependent and personalized selection of TV content. Additionally, lifting content consumption from a single-user activity to a community-based experience in a connected multi-device environment is central to the project. Main research questions relate to (1) data integration and enrichment - how to achieve unified and simple access to dynamic, growing and distributed multimedia content of diverse formats? (2) user and context modeling - what is an appropriate framework for context modeling, incorporating task-, domain and device-specific viewpoints? (3) context-aware discovery of resources - how could rather fuzzy matchmaking between potentially infinite contexts and available media resources be achieved? (4) collaborative architecture for TV content personalization - how can the combined information about data, context and user be put at disposal of both content providers and end-users in the view of creating extremely personalized services under controlled privacy and security policies? Thus, with the grand challenge in mind - to put the TV viewer back in the driver's seat – we focus on TV content as a medium for personalized interaction between people based on a service architecture that caters for a variety of content metadata, delivery channels and rendering devices

The use of evidence in language and literacy teaching

Literacy education deserves evidence-based decisions. Low literacy costs the British economy between £1.73bn and £2.05bn per year (KPMG 2006) and the social and emotional costs are equally high. Yet we know that children who struggle with literacy can make fast progress when the instructional content and pedagogy closely match their needs. This chapter describes some of the paradigms and problems associated with the use of evidence in language and literacy education with examples from specific interventions and programmes. It raises issues about how literacy teachers are professionalized to attend to evidence, both the evidence in front of them and the research evidence 'out there'. It argues that to support teachers in using evidence effectively, we need to frame the research evidence about effective content, pedagogy and learning in ways that recognize the power and limitations of different evidence paradigms. To ensure that all children make fast progress, we need to appreciate how teachers develop broad and diagnostic understandings of literacy and literacy learning and of how policy and curriculum frameworks impact on the classroom decisions they make

Open educational practices for curriculum enhancement

Open educational resources (OER) and open educational practices (OEP) are relatively new areas in educational research. How OER and OEP can help practitioners enhance curricula is one of a number of under-researched topics. This article aims to enable practitioners to identify and implement appropriate open practices to enhance higher education curricula. To that aim, we put forward a framework of four open educational practices based on patterns of OER reuse (‘as is’ or adapted), mapped against the processes of curriculum design and delivery. The framework was developed from the in-depth analysis of 20 cases of higher education practitioners, which revealed patterns of OER reuse across disciplines, institutions and needs. For each open practice we offer evidence, examples and ideas for application by practitioners. We also put forward recommendations for institutional policies on OER and OE
