TINA as a virtual market place for telecommunication and information services: the VITAL experiment

The VITAL (Validation of Integrated Telecommunication Architectures for the Long-Term) project has defined, implemented and demonstrated an open distributed telecommunication architecture (ODTA) for deploying, managing and using a set of heterogeneous multimedia, multi-party, and mobility services. The architecture was based on the latest specifications released by TINA-C. The architecture was challenged in a set of trials by means of a heterogeneous set of applications. Some of the applications were developed within the project from scratch, while some others focused on integrating commercially available applications. The applications were selected in such a way as to assure full coverage of the architecture implementation and reflect a realistic use of it. The VITAL experience of refining and implementing TINA specifications and challenging the resulting platform by a heterogeneous set of services has proven the openness, flexibility and reusability of TINA. This paper describes the VITAL approach when choosing the different services and how they challenge and interact with the architecture, focusing especially on the service architecture and the Ret reference point definitions. The VITAL adjustments and enhancements to the TINA architecture are described. This paper contributes to proving that the TINA-based VITAL ODTA allows for easy and cost-effective development and deployment of advanced end-user and operator services, and can indeed act as the basis for a virtual market place for telecommunications service

The Price Effects of an Emerging Retail Market

In this paper we analyze the effects of changing market structure on price dynamics of final goods in the emerging Czech retail market. We estimate the extent of upstream and downstream market power and find that changing market structure was responsible for an average yearly decrease in the prices of retailed products of 0.8 p.p. during 2000–2005. At the same time, however, we anticipate that the already started period of mergers and acquisitions could cause yearly increases in the prices of retailed products of 1.2 p.p. (approximately 0.5 p.p. in the CPI) over the next ten years.Market structure, retail market, transition economy.

Investigating the Marketing Language among Online Retailers of Violin Strings to Determine the Implied Aesthetic

The aim of this research is to determine if language in the advertising of violin strings is acting as an exclusionary tool in favor of a Western art music “sound” produced by “classical” violinists. It posits that the marketing of strings to violinists is a topic laden with unacknowledged biases and values of musicians within Western art music. The aesthetic values attached to playing Western art music for the violin in the United States are passed on through pedagogic practice and acculturation of language. Product descriptions for strings in the United States employ language which adheres to these cultural values and appeals almost exclusively to practitioners of the Western art canon to the exclusion of other traditions, such as fiddling, which use the same instrument. After establishing the case of aesthetic language as imprecise and exclusionary, the author then proposes that empirical data may be used in combination with said language. Such an approach could provide a more objective perspective on the capabilities of strings and therefore appeal to a more diverse consumer

THE ROLE OF THE RETAILERS IN CAUSE-RELATED MARKETING: A REFERENCE TO THE SPANISH CASE

Cause-Related Marketing (CRM) is one of the most relevant Corporate Social Responsibility (CSR) initiatives nowadays. Its most important characteristic is that corporate donation is conditioned by sales, that is, CRM ultimately depends on consumer behavior. In this paper, we focus on CRM programs and its application in a specific industry: distribution sector. Thus, our aim is to understand the fundamental features or the practice of these programs in the distribution sector in Spain, to study the role played by retailers and their possible influence on the consumer behavior, so that companies can better design these campaigns and achieve greater success. Hence, the paper is organized as follows. First, we review the CRM conceptual framework in which the theoretical development of this work is based. Secondly, and from a list of companies associated to the National Association of Large Distribution Companies (ANGED), the most representative retail association in Spain, we observe the Spanish situation and analyze the main campaigns carried out by these retailers during the last years. This information was completed consulting each retailer´s website, asking them for additional information by email, and with a general internet search. After that, we present and discuss the main results, and summarize the most relevant conclusions, as well as the theoretical contribution and managerial implications. One of the most important findings shows the retailer´s influence on consumer behavior and the key role of the retailers in the success of CRM programs. Finally, we also include possible limitations and further research.</p

Cyber-crime Science = Crime Science + Information Security

Cyber-crime Science is an emerging area of study aiming to prevent cyber-crime by combining security protection techniques from Information Security with empirical research methods used in Crime Science. Information security research has developed techniques for protecting the confidentiality, integrity, and availability of information assets but is less strong on the empirical study of the effectiveness of these techniques. Crime Science studies the effect of crime prevention techniques empirically in the real world, and proposes improvements to these techniques based on this. Combining both approaches, Cyber-crime Science transfers and further develops Information Security techniques to prevent cyber-crime, and empirically studies the effectiveness of these techniques in the real world. In this paper we review the main contributions of Crime Science as of today, illustrate its application to a typical Information Security problem, namely phishing, explore the interdisciplinary structure of Cyber-crime Science, and present an agenda for research in Cyber-crime Science in the form of a set of suggested research questions

Service creation and deployment on an intelligent network

Active competition in the telecommunications industry has caused a dramatic shift in focus for public network operators. Service designers need to be able to easily and rapidly create services according to the customer’s requirements. This is achievable by using Intelligent Networks (INs). Two primary goals of service development under the Intelligent Network paradigm are rapid service crcation using new software technologies and the minimisation of service development costs through switch vendor independence. This thesis examines the development of an IN architecture and the deployment of two call control services on it using the ITU-T Service Independent Building Block (SIB) methodology. The services are deployed on a narrow-band Excel switching platform. Various aspects of the IN Conceptual Model (INCM) are examined with a particular emphasis on the middle two planes: the Global Functional Plane (GFP) and the Distributed Functional Plane (DFP). Representations of these planes are designed using the ITU-T Specification and Description Language (SDL) [SDL89] and implemented using Telelogic’s SDL Development Tool (SDT). SDL provides capabilities to allow logical structuring of the INCM into its constituent entities, the modelling of communication between these entities and the processing within them. The Intelligent Network paradigm was developed with a view to extendibility. Two call control services, Ringback and Group Call Pickup, are implemented using the SIB methodology. Further services may be created by rearranging the order of execution of the existing SIBs or, if necessary, by adding new SIBs to the architecture. Given the demand for multimedia applications to run on top of emerging broadband networks it is becoming increasingly more important for network operators to study the enhancement and evolution of their IN service platforms in order to cope with new customer requirements. TINA is the leading architecture for multimedia service control and delivery, which defines an emerging open service platform. Migration from IN to TINA is explored in this thesis by considering two individual paths of migration. The first path involves the replacement of the IN service control and management elements (SCF, SMF, SDF) with appropriate TINA Computational Objects while the switching elements (SSF, CCF) remain IN compliant. As there is no one-to-one mapping of IN functional entities to TINA computational objects, an Adaptation Unit is required to facilitate interaction between the legacy IN entities and the TINA Computational Objects. The advantage of this step is that it is possible to keep the investment of deployed IN SSPs while taking advantage of TINA service modelling. The second step involves the introduction of TINA into the switch. In this approach the switch and its switching capabilities may be viewed as a TINA object in itself. Interworking between IN and TINA (as a step towards full migration to TINA) yields a much richer service platform. This service platform facilitates the creation of services that incorporate both IN and TINA features. A TINA service may use pieces of IN functionality and IN services may also use TINA functionality. It is possible to invoke these hybrid services from either a PSTN or a TINA terminal. Three hybrid IN/TINA services were designed to demonstrate the increased resources available to the service designer using such a platform. A user connected to the IN switch invokes the Freephone Service. This service uses a TINA database to convert the 1-800 number to an extension number. The call is then connected using IN switching functionality. The Audio Video Conference, uses TINA computational objects to set up a video stream between participating users while the audio connection is handled by the IN switching functionality. This service is invoked from a TINA terminal. A user connected to the IN switch invokes the Ringback Service but it runs in the TINA domain using both TINA and IN functionality. Therefore, as well as presenting an application of the IN technology, this thesis proposes possible steps towards migration to the TINA architecture

Overview on the current organizational models for cultivar testing for Organic Agriculture over some EU countries.

Variety trials are an important way to evaluate the suitability of existing varieties (conventional, organic, landraces, heirloom, etc.) for organic farming, and are a necessary step in plant breeding and variety registration. However, it is essential that beside on-stations trials, varieties are also tested on-farm in different climatic regions as this gives more accurate and realistic variety performance assessment (Lyon et. al. 2019). Varieties of different crop species are in service to various stakeholders. Thus, their involvement may play an important role in variety trials. They could contribute, with knowledge, seed material in kind or financial support, to build cost-effective variety testing models also for crops that are not grown on a large scale and have small market share. In the report evaluation of different organic variety trials for pre- and post-registration as well as VCU across 15 EU countries (for arable incl. forage, vegetable and fruit crops) is presented through 4 main criteria (trial setup, organizational model, dissemination of results and financial model). Through the range of organizational models of variety trials there were some that were mainly governmentally supported and involving researchers, others that have strong engagement of breeders and seed companies, or are done within seed companies, and some that are running just if project financing is available or some that are mainly established by farmers and done on voluntary basis. Organizational models of variety trials have quite complex nature and therefore, it is not possible to give a general recipe for establishing successful variety trials network. Institutes or initiatives organize trials depending on different socio-economic conditions, such as financial possibilities, economic importance of the crop in the country, chain actors’ engagements, organic sector development, existing trial infrastructure etc. In the report, SWOT analysis of different organizational model groups give better understanding of pros and cons of the different systems and show necessary infrastructure for different models. These analyses will serve as a base for development of guidelines for on-farm trials models that are low budget, with alternative financing and new infrastructures

A framework for abstracting complexities in service delivery platforms

The telecommunication (telco) and Information Technology (IT) industries are converging into a single highly competitive market, where service diversity is the critical success factor. To provide diverse services, the telco network operator must evolve the traditional voice service centric network into a generic service centric network. An appropriate, but incomplete, architecture for this purpose is the Service Delivery Platform (SDP). The SDP represents an IT-based system that simplifies access to telco capabilities using services. SDP services offer technology independent interfaces to external entities. The SDP has vendor-specific interpretations that mix standards-based and proprietary interfaces to satisfy specific requirements. In addition, SDP architectural representations are technology-specific. To be widely adopted the SDP must provide standardised interfaces. This work contributes toward SDP standardisation by defining a technology independent and extendable architecture, called the SDP Framework. To define the framework we first describe telecom-IT convergence and a strategy to manage infrastructure integration. Second, we provide background on the SDP and its current limitations. Third, we treat the SDP as a complex system and determine a viewpoint methodology to define its framework. Fourth, we apply viewpoints by extracting concepts and abstractions from various standard-based telecom and IT technologies: the Intelligent Network (IN), Telecommunication Information Networking Architecture (TINA), Parlay, enhanced Telecommunications Operations Map (eTOM), Service Oriented Architecture (SOA) and Internet Protocol Multimedia Subsystem (IMS). Fifth, by extending the concepts and abstractions we define the SDP framework. The framework is based on a generic business model and reference model. The business model shows relationships between SDP, telco and external entities using business relationships points. The reference model extends the business model by formalising relationships as reference points. Reference points expand into interfaces exposed by services. Applications orchestrate service functions via their interfaces. Service and application distribution is abstracted by middleware that operates across business model domains. Services, interfaces, applications and middleware are managed in Generic Service Oriented Architectures (GSOA). Multiple layered GSOAs structure the SDP framework. Last, we implement the SDP framework using standard-based technologies with open service interfaces. The implementation proves framework concepts, promotes SDP standardisation and identifies research areas
