Abstract:
The competitive nature of Internet access service business drives Service Providers to find innovative revenue generators within their core competencies. Internet connection is the essential infrastructure in the current business environment. Service Providers provide the Internet connections to corporate networks. It processes network data to enable the Internet business communications and transactions. Mining the network data of a particular corporate network resulted in its business traffic profile or characteristics. Based on the discovered characteristics, this research proposes novel generic Value Added Services (VAS). The VAS becomes the innovative and competitive revenue generators. The VAS is competitive as only the Service Provider and its customer know the traffic profile. The knowledge becomes the barrier of entry for competitors. To offer the VAS, a Service Provider must build close relationship with its customer for acceptance.

Abstract:
The Italian Public Administration (PA) consists in a wide set of local authorities (i.e., regions, provinces and municipalities) providing services to citizens, each with its own administrative autonomy. Actually, it often happens that Italian citizens have difficulties in discovering and using services that they need in the course of their lifes. Several Italian initiatives, suchas the SMART (Services and Meta-services for smart e-Government) project, aim to simplify the interaction between Italian citizens and the PA trought the definition of value -added services. A value-added service (VAS) guides the citizen in the fruition of all services needed along a life event (e.g., the change of address). In this paper, we present a new version of the Italian Public Administration Service (IPAS) model defined for the description of PA services. We will show how the new model supports the description of concepts that simplifies the definition of VAS. A case study defined in the context of the SMART project will be presented.

Abstract:
Traditional banking methods evolved and include services as a method of differentiation, reducing operating costs, and providing additional benefits to the customer. Banks re-invented themselves and provide innovative solutions to remain competitive. This research explores whether using value added services contributed to changes in transactional banking behaviour and was done in one of the largest banks in South Africa over a period of four months. Two banking products in the youth customer segment were selected. The control group received one treatment at the beginning of the four-month period, and the experimental group received a further three treatments at different times of each month. Two data sets (1) VAS usage and (2) bank transactions were analysed. The results showed that the intervention had a positive effect on transactional banking behaviour. Additional causative factors were identified that increased the usage of value-added services and increased transactional banking behaviour.

Abstract:
This article examines the value-added services (VAS) market. The production of these services requires the cooperation of assets and competences owned by different categories of firms. The first part of the paper points out the nature of the services and identifies a number of firms which are involved in the VAS production. The second part of the paper is based on a statistical analysis of an original sample. Three classes of services are discriminated: enhanced communication services, dedicated services, and information services. Then, we focus our attention on the dedicated services. A detailed analysis of this category enables us to identify three sub-groups of services: specialized communication services, community services and on line transaction services. Moreover the production of these dedicated services is driven by users. It is concluded that users have gained control over a wide segment of the VAS market because they own some specific competences and knowledge.

Abstract:
Purpose Considering the resource constraint, this paper aims to study how to make value-added service (VAS) investment strategy considering the negative intra-group network externality on the seller side from the perspective of a two-sided platform. Design/methodology/approach The authors use the dynamic game theory, optimization, sensitive analysis and numerical study in this research. The authors model their research question from the perspective of the dynamic game theory, and through optimizing the platform’s profit function, the equilibrium results in terms of VAS investing and pricing strategies are derived. To explore the characteristics of the optimal strategies, sensitive analysis is used, and numerical studies are conducted to further illustrate the analytical results. Findings It is found that the intra-group network externality is not necessarily the determinant for VAS investment strategy, and its overall negative impact can be overtaken by the investment in certain conditions. The optimal VAS investment level decreases in the negative intra-group network externality. Though the VAS investment is on the seller side, it has either positive or negative impact on the pricing for buyers. Moreover, for a stronger intra-group network externality among sellers, the two-sided prices could either increase or decrease. Research limitations/implications The authors implicate how the intra-group network externality reduces the investment benefit and impacts the other side users. The limitation of considering the intra-group network externalities on only one side needs further extension. Practical implications The authors provide insights for platform operators in how to use recourse to improve users’ utility and how to price the two sides when competition exists on the seller side. Originality/value This study specifies the role of negative intra-group network externality in determining the investment and pricing strategy of a two-sided platform in addition to the positive inter-group network externality.

Abstract:
Purpose – Despite an increasing policy focus, routine outcome monitoring (ROM) is not common practice in UK children's services. This paper aims to examine whether it is feasible and valid to use measures from ROM of evidence-based parenting programmes (EBPPs) to assess the impact of services and to drive service improvements through feedback mechanisms. Design/methodology/approach – This is a secondary analysis of ROM measures collected from a London clinic offering EBPPs over five years. Demographic information from referrals was compared for attendees and non-attendees. Changes in parent reported child behaviour were measured using the Strengths and Difficulties Questionnaire (SDQ), and a Visual Analogue Scale (VAS). Findings – No significant differences were found in socio-demographic characteristics of attendees and non-attendees. Statistically significant differences were found between pre- and post-scores on parent reported SDQ scores and VAS concerns, as well as the SDQ Added Value Score. The data collected did not allow for investigation of a dose-response relationship between the level of attendance and any improvement made. Originality/value – This study illustrates that ROM can provide useful information about the impact of EBPPs in a particular clinical context. Demographic data could support service managers to evaluate reach and uptake while evidence of improvements can be communicated back to parents and support future funding bids. Incomplete data limited the inferences that could be drawn, and collaborations between research centres and clinics may be a way to optimise the use of ROM to drive service improvement and innovation.

Subject area Pricing, digital marketing, marketing management and strategic marketing. Study level/applicability The case can be used for pricing or digital marketing courses as well as marketing management courses to MBA students and/or for management development programmes. Case overview Goldfinch Mobile Solutions, a Hong-Kong based value added services (VAS) and gaming platform provider, had an exclusive tie up with Bharti Airtel in India for providing value added voice applications on an interactive voice response system (IVRS) platform. The Goldfinch flagship service is “Guru Ki Bani” which may be subscribed to by dialing the short code 58282. This “58282” service has a repository of all Sikh religion daily prayers, religious songs, teachings, stories from Guru's life and similar information that is derived from the Sikh Holy book Guru Granth Sahib Ji. As per mutual agreement between Goldfinch Mobile Solutions and Bharti Airtel, the telecom operator had the responsibility to promote Goldfinch's Guru Ki Bani service amongst its subscriber base through its below the line (BTL) promotional channels such as short messaging service (SMS), outbound calls, cell information, notification SMS after call and above the line (ATL) activities such as posters, leaflets, print, promoters, regional TV, outdoors, etc. The revenue sharing arrangement between Airtel and Golfinch was in the ratio of 75 percent and 25 percent. However, with recent changes in the policies of Telephone Regulatory Authority of India (TRAI), promotional marketing used by telecom operators has been constrained. Declining customer share, decreasing profits (after Bharti Airtel halted promotions) and increasing organization cost per customer have made MD and CEO Mr Newton Bubber think of various options including low-cost marketing initiatives besides digital marketing to promote Guru Ki Bani services. Value communication to its huge potential customer base, i.e. 184.19 million Bharti Airtel subscribers was another challenge facing Mr Newton and his marketing team at Goldfinch. Expected learning outcomes The case enables students to learn the concepts and application of value creation, effective value communication, price waterfall analysis, importance of costing parameters in pricing decisions, low-cost marketing strategies and digital marketing.

Abstract:
Value Added Services (VASs) have become one of the major revenue generators in the telecom industry. Most of the telecom subscribers have started using VAS and it has become an important service for the customers. The objective of the project is to evaluate and analyse the need for value added services in India. The report begins with a discussion of existing VAS provided by 2G wide area cellular technologies and how these will change with the introduction of 3G technology. Following this the value chain of VAS is discussed. Next new trends, drivers, and challenges of the VAS are discussed in detail. The impact of content developers and software development on VAS are discussed. Then a method to analyse VAS is discussed, followed by method of analysing the ringback tones with respect to a company is provided followed by the method to analyse the importance of the content providers in the value chain. Then the Mobile commerce VAS is analysed in detail and ringback tone service provided by OnMobile Company is analysed in detail, followed by an analysis of the role of content providers in value chain. A survey on different services provided through VAS is taken among few of the VASs users in India and the results are included with graphs in the report. The thesis analysis results are very important in the modern telecommunication industry as VAS plays a major role in generating huge revenue and currently many industries are focusing on to provide mobile commerce services to its customers. The thesis answers various questions like, what are the different M-commerce services that are provided to the customers in the telecom industry. Why OnMobile Company provides different varieties of ringback tones to the user? Why the role of content providers is very important in the Value chain? The report concludes with conclusions explaining the different insights that are gained from the analysis of the VAS (M-Commerce), Ringback tones provided by OnMobile, role of content providers in the Value chain and the survey results. It is followed by the some suggestions and possible future work concerning Value Added Services in India.

Abstract:
This article analyzes the definitions of the main taxable events for the Value-Added Tax (VAT) based on a comparative approach to thelegislation of different countries (Spain, Mexico, Chile, Colombia, Argentina and Peru). In this regard, it analyzes which legislations offer definitions according to the principles of generality, fiscal neutrality and legal certainty for VAT. Moreover, it points out that the VAT systems of those countries do not require as a condition for the configuration of the taxable events that the transactions involve a «value added» or a final consumption. In the specificcase of «supplies of goods», the VAT systems have a similar definition of the taxable event, although there are a few differences. However, in the case of«supplies of services», which is the most important taxable event for VAT, there are important differences at the time each country defines it. This is not a desirable effect for the international trade of services, since the lack of harmonization produces double taxation or double non taxation.
El trabajo aborda la definición de los hechos gravados principalesen el Impuesto al Valor Agregado (IVA) en el derecho comparado (España, México, Chile, Colombia, Argentina y Perú), evaluando qué legislaciones proponen una definición conforme a los principios de generalidad, deneutralidad y de seguridad jurídica. Destaca que ninguna de las legislaciones exige como condición para la configuración de los hechos gravados que setrate de transacciones que generen «valor agregado» o que se trate de bienes o servicios susceptibles de consumo final. En el caso de la venta de bienes muebles, hay coincidencia en la definición del hecho gravado, aunque con matices de diferencia. En cambio, en la definición de servicios, que es la hipótesis más importante del impuesto, hay grandes diferencias entre las legislaciones. Ello definitivamente no es deseable, considerando el comercio internacional de servicios, por cuanto la falta de armonización produce fenómenos de doble imposición y doble no imposición.

Abstract:
South Africa’s VAT legislation has specific value and time of supply rules. It does not have a specific section for place of supply rules, but this is however incorporated within the various sections of the Act. Still, there is sometimes uncertainty regarding what the place of supply would be, especially when it comes to telecommunication services across borders. Some foreign countries, like European countries, have specific place of supply rules. However, South Africa does not specify where the specific place of supply of telecommunication services should be. International roaming complicates matters as a South African resident can visit a foreign country and make calls from the foreign country to yet another country, but is then billed in South Africa at a rate including VAT at 14%. One could argue that this is not the correct treatment as it could be deemed an export of services, which would generally be zero-rated. During the interviews it was discovered that the foreign network operator billed the South African network operator for the services rendered to the South African operator’s customer in the foreign country. Some operators levy VAT on this charge at that country’s VAT rate, whereas other countries’ operators will levy at a rate of zero percent. However, the South African resident is levied at a charge including VAT at 14%, regardless of whether the operator was charged VAT by the foreign operator or not. Costs of international roaming are already high and, therefore, international roaming can become very expensive for customers. The researcher suggests that the agreement be revisited and that VAT is only charged in the country where the consumption of the supplies takes place, or in the case of a service, where the service is utilized. It is however much more complex with telecommunication services as there are various networks that go through numerous countries, and can include the customer’s home country. AFRIKAANS : Suid-Afrika se BTW-wetgewing het reëls wat spesifieke waarde en tyd van lewering bepaal. Hoewel dit nie 'n spesifieke artikel het met reëls wat handel oor die plek van lewering nie, is dit egter in die verskillende artikels van die wet geïnkorporeer. Tog is daar soms onsekerheid oor waar die plek van lewering is, veral wanneer dit telekommunikasiedienste raak wat oor grense verskaf word. Sommige lande, byvoorbeeld Europese lande, het spesifieke reëls wat plek van lewering bepaal. Suid-Afrika spesifiseer egter nie die spesifieke plek van lewering van telekommunikasiedienste nie. Internasionale selfoon swerwery kompliseer sake omdat 'n Suid-Afrikaanse inwoner die buiteland kan besoek en oproepe van daar na nog 'n ander land maak, maar steeds in Suid-Afrika gefaktureer word teen 'n koers insluitend BTW teen 14%.’n Mens kan argumenteer dat dit nie die regte hantering is nie omdat dit 'n uitvoer van dienste geag kan word, wat gewoonlik genulkoers word. Daar is tydens die onderhoude ontdek dat die buitelandse netwerk-operateur die Suid- Afrikaanse netwerk-operateur faktureer vir die dienste aan die Suid-Afrikaanse operateur se kliënte in die buiteland. Sommige operateurs hef BTW op hierdie koste teen die koers van daardie land se BTW, terwyl ander lande se operateurs teen 'n koers van nul persent sal hef. Die Suid-Afrikaanse inwoner word egter teen ‘n koste insluitend BTW van 14% gefaktureer, ongeag of die operateur deur die buitelandse operateur teen ’n koste insluitend BTW van 0% of ‘n ander persentasie gefaktureer is. Koste van internasionale selfoon swerwery word gehef in die land waar die voorrade gebruik word, of in die geval van 'n diens, waar die diens gebruik word. Die koste kan baie hoog wees. Dit is egter baie meer kompleks met telekommunikasiedienste omdat daar verskeie netwerke is wat deur talle lande kan gaan. Dit kan moontlik in die kliënt se land van herkoms ook wees.

Abstract:
The aim of this dissertation is to analyse whether the current VAT treatment for educational institutions is still valid given the development within these institutions and if not, to identify alternative VAT treatments that may be used. Educational services are an exempt supply under section 12(h) of the VAT Act. The main reason for the exemption of educational services is that many of the institutions providing educational services were government institutions and to some extent financed by the government. However, over the years, the activities of institutions providing educational services have changed drastically and a reduced number of institutes are wholly subsidized in terms of government subsidies. In order to aid government grants and increase income, these institutions have increased their taxable activities considerably. Furthermore, privately owned and semi-subsidized institutions are accountable for their own costs and are not provided any or limited support from government. Numerous educational institutions within South Africa conduct an enterprise with the rendering of taxable supplies in addition to the provision of educational services. Such additional activities, provided the educational institute qualifies for and is VAT registered, are taxed at the standard rate. This in turn has created complications in administering the VAT Act, whereby these service providers are then required to carry out an apportionment calculation of VAT on their mixed supplies. This practice is inefficient and not cost effective. Furthermore, the ease of compliance, which was the basis in implementing the exemption, is diminished, as registration for VAT purposes is unavoidable. Educational institutions that render taxable supplies would be incurring inputs on associated costs. The effect of exempting educational services from the VAT net ultimately results in an increase in tuition fees as the burden of “hidden” or “trapped” cost is passed onto the student, as a result of the institution’s inability to claim a refund of the tax paid. As there is no recovery of input tax embedded in the price of exempt supplies, the cost of the tax included in the price must be borne by the entity that acquires the exempt supply and can only be recovered if the tax is passed on to customers. This is in effect contradictory to the initial intention of the government’s political and economic objective in respect of education, to ensure access to education to all on a non-discriminatory basis. As the objective and intention of the legislation towards exempting educational services is no longer satisfied, it must be reassessed and the treatment relating thereto re-examined. The first alternate VAT treatment recommended is for educational services to be zero rated, this will reduce the administrative burden most educational institutions currently face in terms of carrying out complex apportionment calculations and will keep with the original intention of the VATCOM. Furthermore educational institutions will have additional funding via the release of input tax credits which may potentially result in a reduction in the percentage increase in student fees in future periods the burden of the ‘hidden’ or ‘trapped cost’ will not be passed onto the student. Other VAT treatments recommended should zero-rating fail is to tax educational services at a reduced rate or include educational services as a welfare organization activity. Should the above-recommended VAT treatments not be feasible it is suggested that the current VAT treatment be improved by providing additional guidance on what supplies can be included as educational services.

Abstract:
Value-Added Services and Content Platforms (VAS and Content platforms) was carried out with in a group with same name at Tele2 AB in Kista, Stockholm. This group is responsible for network design, capacity planning, dimensioning, Acceptance testing (ATP test), and introducing of new functionality in Tele2's VASplatforms. Acceptance testing is performed on new devices (servers and other network components) in order to verify their capacity and performance guaranteed by their manufactures. Every platform has a guaranteed upper bound performance (based on the license a buyer has paid for), measured by different approaches. For instance for Short Message Service Center (SMSC) platforms, the measurement is based on the maximum number of SMS messages processed per second (SMS/sec), for Multimedia Messaging Service Center (MMSC) platforms the metric is the maximum number of MMS messages processed per second (MMS/sec), and for WAP Gateways it is the maximum number of WAP Transactions Per Second (TPS). This M.Sc. thesis project involved creating two graphical load generators for load testing of SMSC and MMSC platforms. These application-programs are not allowed to occupy unnecessary resources, or cause additional traffic on the radio network (when they are deployed), but they must be powerful enough in order to send and receive traffic in order to derive statistical data about the system's performance. This data will be used for behavioral analysis of these systems, and finally for verifying the guaranteed capacities. These tests are very important and decisive for service providers, who want to be able to offer good quality of service, guarantee availability, and offer reliability. In order to measure the performance and verify the guaranteed performance, two main scenarios were of great importance: Sending 5 messages per second during a interval of 5 minutes. This case will simulate a TV-contest in which the TV audiences submit messages to a predefined number in order to join the contest. Sending 3 Multimedia Messages per second during 30 minutes (for the MMSC performance measurement), and 7 SMS-messages per second during 120 minutes (for the SMSC performance measurement). This case attempts to simulate the traffic that will be generated in the minutes before and after Christmas or New Year. For behavioral analysis and performance measurement of the MMSC and the SMSC platforms an Open Queueing Network model is employed. In this model each server system is considered as a network, consisting of nodes, where each node represents one component inside the system. By considering each node as a single-server queueing system we can take advantage of queueing theory in order to drive several performance results.

Abstract:
The digital economy is growing exponentially. Companies such as Facebook and Instagram base their business model on supplying services completely free of charge to billions of users.  This model of business is called “Freeconomics”. These companies generate huge profits from the exploitation of personal data provided by Users. The peculiarity of this way of doing business, although this may seem absurd, is that the company's profit is directly proportional to the number of non-paying users. Such situations have given rise to discussions regarding the powerlessness of the tax system of states to levy tax on such profits. Regarding the indirect taxation, the question is even more difficult if one considers free digital services and personal data. Unfortunately, this flow of “digital” consumption remains completely out of a VAT assessment. Exclude a priori those transactions from being assessed for VAT purposes only because it could be arduous to assess the consumption would result in a violation of the principle of neutrality. Accordingly, issues related to the distortion of competition could also arise. The author of this thesis examines the assumption that between the Companies and the Users take place a reciprocal exchange of benefits in kind characterized by a synallagmatic relationship (quid pro quo) in the form of barter. The results of the analysis indicate that the transactions characterized by the supply of free digital services to Users in exchange for personal data - as described in the Business Reference Model - actually fall within the scope of Article 2 (1)(c) of the EU VAT Directive and therefore must be subject to indirect taxation.

The ongoing mobile revolution has dramatically and fundamentally changed our daily lifestyles, and it will continue to do so in a foreseeable future. For the next generation, mobile service end users have more demands for such services. This thesis examines the challenging user perspectives in designing and developing high value added mobile services. The aim of this research is to develop reference models and elicit user requirements for 3G and beyond mobile services in order to improve the quality of mobile services. This thesis first examines the existing architectures and models for high value added mobile services, followed by the contributions of the thesis. In this thesis, a Cyberworld model, which is a contribution to the WWRF reference modeling initiative and a specification of the WSI reference model, was developed and it serves as a basis for 3G and beyond mobile services design and development. A series of definitions of the Cyberworld model and a roadmap of the enabling technologies were also built up. The emphasis of this part is on how to describe and model user participation in mobile services. For this purpose, a model of the communication element to represent the components of the wireless world was created. Both static and dynamic reference modeling steps were established to better describe and understand user participation in mobile services. The validation was achieved through the CyPhone navigation mobile service. In order to enhance mobile service mobility, personalisation, and security, an ontology based model was developed to extend the Cyberworld model functionalities. The innovative ontology based mobile system will greatly increase service mobility, personalisation and security, thus improving the quality of mobile services. The ontology based model was illustrated and validated using a healthcare mobile service. A Quality Function Deployment (QFD) approach was adopted in this research in order to elicit, weigh and prioritise actual user requirements and link them to technical design requirements of mobile services. Traditionally QFD is employed in manufacturing industry. This approach is now extended to the mobile service industry for the first time. In this thesis, a detailed step by step QFD approach was proposed for designing high value added mobile services. As a result, the developed mobile services will better meet users' wants and needs which also means that the quality of mobile services will be significantly improved. The QFD approach was validated through a mobile e-learning service and another dedicated healthcare service for senior citizens. Through development of reference models and examination of user requirements for 3G and beyond mobile services from user perspectives, this thesis contributes to the design and development of high value added mobile services.

Abstract:
The subject of this research is to find a continuous solution, which allows the description, the creation, the provisioning, and the execution of value-added telecommunication services. This work proposes a framework for an easy and timesaving creation and provisioning of value-added telecommunication services in Next Generation Networks. As research method, feasibility, comparative methods are used in this study. Criteria and requirements for service description, service creation, service execution, and service provisioning, are defined and existing technologies are compared with each other and evaluated regarding these criteria and requirements. Extensions to the selected technologies are proposed and possibilities to combine these technologies are researched. From the results of the previous steps, a framework is defined which offers a continuous solution for the description, creation, provisioning and execution of value-added services. In order to test the proof of concept, this framework is prototypically implemented. For a qualitative analysis of the research targets and the proof of concept, an example service is created and executed within the framework prototype. Furthermore, in order to examine the validity of the quantitative aims and objectives of this research work, a second example service is created, and its characteristics are measured and analysed. The result of this research is a novel continuous approach for the creation of value-added telecommunication services. This research introduces new possibilities for the service description, service creation, service provisioning, and service execution through an extension of the common telecommunication real-time execution environment JAIN SLEE. Value-added services are described by using the business process execution language BPEL. This language facilitates a simple and fast service design. The service can automatically be composed from pre-defined and pre-deployed components.

This study aimed to understand the intellectual capital role, in the value creation process, throughout the different phases of the business model, in a mobile value added service (VAS) company. The theoretical constructs of value, intellectual capital, business model and process perspective, have been reviewed. From these constructs, a conceptual model has been developed. This model is able to integrate human, structural and relational dimensions of intellectual capital, and guide them to process of creating, delivering and capturing value for the company, through a business model evolutionary perspective. The conceptual model was empirically applied to the Movile company, a VAS technology developer, through a single case study, carried out at an interval of 18 months, in a period comprised between april 2013 and september 2014. Data were collected from six interviews, and complemented by primary and secondary artifacts, as well as by direct observations. As a result, it has been observed that human, structural and relational dimensions of intellectual capital, are closely related to value creation process, and were gradually built and hinged along an organizational evolutionary process, of more than 15 years. During this period, six different business models were identified, involving the past, present and future of the company. In the initial phase, human and relational dimensions were essential to value creation. In subsequent steps, there was an importance alternation of dimensions in value creation process, and an enhancement of each dimension features, showing the relational dimension as a determining factor for value creation in the company long-term future. As an empirical contribution, the business model evolutionary analysis, through the articulation of the intellectual capital dimensions, provides analytical elements for new companies that emerge in Mobile VAS industry. In relation to the telecommunications companies, these tend to turn into a pipe performance, substantially focused on providing technology infrastructure to mobile VAS companies.
Teve-se como objetivo, neste estudo, compreender o papel do capital intelectual no processo de criação de valor ao longo das diferentes fases evolutivas do modelo de negócio de uma empresa de Serviço de Valor Agregado (SVA) móvel. Foram revisados os constructos teóricos de valor, capital intelectual, modelo de negócio e perspectiva processual. A partir deles, foi desenvolvido um modelo conceitual capaz de integrar as dimensões humana, estrutural e relacional do capital intelectual, e orientá-las ao processo de criação, entrega e captura de valor para a empresa, numa perspectiva evolutiva de modelo de negócio. Esse modelo conceitual, foi aplicado empiricamente na empresa Movile, desenvolvedora de tecnologia SVA móvel, por meio de um estudo de caso único, realizado em um intervalo de 18 meses, entre abril de 2013 e setembro de 2014. Os dados foram coletados mediante a realização de seis entrevistas e complementados por artefatos primários, secundários e observações diretas. Como resultado, pôde-se observar que as dimensões humana, estrutural e relacional do capital intelectual, encontram-se intimamente relacionadas ao processo de criação de valor, e foram gradativamente construídas e articuladas ao longo de um processo evolutivo organizacional de mais de 15 anos. Nesse período, foram identificados seis diferentes modelos de negócio, envolvendo o passado, presente e futuro da empresa. Na fase inicial, observou-se que as dimensões humana e relacional foram essenciais para a criação de valor. Nas etapas subsequentes, observou-se uma alternância da importância das dimensões no processo de criação de valor, e um aprimoramento e modificação das características de cada dimensão, evidenciando ser a dimensão relacional o fator determinante para a criação de valor em um futuro de longo prazo da empresa. Como contribuição empírica, a análise evolutiva do modelo de negócio, por meio da articulação das dimensões do capital intelectual, fornece elementos analíticos para as novas empresas que venham a surgir e se estabelecer no setor de SVA Móvel. No tocante às operadoras de telecomunicações, observou-se que essas tendem a evoluir para uma atuação de pipe, substancialmente voltada para o fornecimento de infraestrutura tecnológica às empresas de SVA móvel.

Abstract:
The attributes of education in a digital neighborhood have warranted a community of teachers on one end with shared curriculum and teaching materials and another community of students with distance and distributed learning on the other end. There is a different kind of ecology emerging and the library professionals have the opportunity to create a world without borders, making everything available to everyone anytime, anywhere. Roles of libraries have changed from being traditional to exist as hybrid or electronic libraries. In turn, the Library and Information Science (LIS) professionals have become intelligent filters of information and contribute to the libraries to emerge as â Knowledge Resource Centersâ . Creating successful e-information services for its demanding clientele has become their major challenge. One such case study of e-information services provided by the Science Campus (Guindy Campus) Li-brary of University of Madras is focused in this paper. The Campus Library caters to the re-search community of Schools of Life, Physical, Chemical, Earth Sciences and an array of re-searchers (members) from industries. Periodic discussions with experts, faculty and research scholars have necessitated the Library to enhance research with Information Gateways on spe-cific themes. Subject Gateways on Biomedical Sciences, Life, Chemical, Physical and Inter-disciplinary Sciences are compiled periodically and made available on the intranet in turn making its clientele access the sources on the internet from their desktop. They not only sup-plement research but also new popular courses introduced, thrust of the University programs and so on. The Gateway focused here is â Nutraceuticalsâ which is a component of the Gate-ways on â Biomedical Sciencesâ . The methodology of information aggregation from the Inter-net, evaluating their validity and organizing them for access, the strategies used to market the e-service, such as organizing user education and information literacy programs are discussed. Methods of evaluation of the service provided are analysed to improve the same. The chal-lenges of the career to develop essential skills to combat technology have compelled the pro-fessionals at the Library to get trained and update their technical expertise. Thus the Library tries to support the evolutionary convergence of Library Services, Technology and the Clien-tele.

Abstract:
As the global community works toward the Sustainable Development Goals, closer integration between governance and sectoral interventions offers a promising, yet unproven avenue for improving health service delivery. We interrogate what value an integrated governance approach, intentionally combining governance and sectoral investments in strategic collaboration, adds to health service readiness and delivery using data from a study in Senegal. Our quasi-experimental research design compared treatment and control communes to determine the value added of an integrated governance approach in Senegal compared to health interventions alone. Our analysis shows that integrated governance is associated with improvements in some health service delivery dimensions, specifically, in aspects of health facility access and quality. These findings—that health facilities are more open, with higher quality infrastructure and staff more frequently following correct procedures after integrated governance treatment—suggests a higher level of service readiness. We suggest that capacity building of governance structures and an emphasis on social accountability could explain the added value of integrating governance and health programming. These elements may help overcome a critical bottleneck between citizens and local government often seen with narrower sector or governance-only approaches. We discuss implications for health services in Senegal, international development program design, and further research.

Abstract:
In Colombia, as well as in the rest of the world, the Covid-19 pandemic has seriously damaged the health and well-being of the people. In order to limit the damage, local and national authorities have had to order large sectors of the population to be confined at their homes for long periods of time. An inevitable consequence of isolation has been the collapse of economic activity, expenditure, and employment, a phenomenon that has hit many countries of the world affected by the disease. It is an unprecedented crisis in modern times, not so much for its intensity (which is undoubtedly immense), but because its origin is not economic. That is what makes it so unpredictable and difficult to manage. Naturally, its economic consequences are enormous. Governments and central banks from all over the world are struggling to mitigate them, but the final solution is not in the hands of the economic authorities. Only science can provide a way out. In the meantime, the economic indicators in Colombia and in the rest of the world cause concern. The output falls, the massive loss of jobs, and the closure of businesses of all sizes have become daily news. Added to this, there is the deterioration in global financial conditions and the increase in the risk indicators. Financial volatility has increased and stock indexes have fallen. In the face of the lower global demand, export prices of raw materials have fallen, affecting the terms of trade for producing countries. Workers’ remittances have declined due to the increase of unemployment in developed countries. This crisis has also generated a strong reduction of global trade of goods and services, and effects on the global value chains. Central banks around the world have reacted decisively and quickly with strong liquidity injections and significant cuts to their interest rates. By mid-July, such determined response had succeeded to revert much of the initial deterioration in global financial conditions. The stock exchanges stopped their fall, and showed significant recovery in several countries. Risk premia, which at the beginning of the crisis took an unusual leap, recorded substantial corrections. Something similar happened with the volatility indexes of global financial markets, which exhibited significant improvement. Flexibilization of confinement measures in some economies, broad global liquidity, and fiscal policy measures have also contributed to improve global external financial conditions, albeit with indicators that still do not return to their pre-Covid levels.

African Open Science Platform Part 1: Landscape Study. Academy of Science of South Africa (ASSAf), 2019. http://dx.doi.org/10.17159/assaf.2019/0047.

Full text
Abstract:
This report maps the African landscape of Open Science – with a focus on Open Data as a sub-set of Open Science. Data to inform the landscape study were collected through a variety of methods, including surveys, desk research, engagement with a community of practice, networking with stakeholders, participation in conferences, case study presentations, and workshops hosted. Although the majority of African countries (35 of 54) demonstrates commitment to science through its investment in research and development (R&D), academies of science, ministries of science and technology, policies, recognition of research, and participation in the Science Granting Councils Initiative (SGCI), the following countries demonstrate the highest commitment and political willingness to invest in science: Botswana, Ethiopia, Kenya, Senegal, South Africa, Tanzania, and Uganda. In addition to existing policies in Science, Technology and Innovation (STI), the following countries have made progress towards Open Data policies: Botswana, Kenya, Madagascar, Mauritius, South Africa and Uganda. Only two African countries (Kenya and South Africa) at this stage contribute 0.8% of its GDP (Gross Domestic Product) to R&D (Research and Development), which is the closest to the AU’s (African Union’s) suggested 1%. Countries such as Lesotho and Madagascar ranked as 0%, while the R&D expenditure for 24 African countries is unknown. In addition to this, science globally has become fully dependent on stable ICT (Information and Communication Technologies) infrastructure, which includes connectivity/bandwidth, high performance computing facilities and data services. This is especially applicable since countries globally are finding themselves in the midst of the 4th Industrial Revolution (4IR), which is not only “about” data, but which “is” data. According to an article1 by Alan Marcus (2015) (Senior Director, Head of Information Technology and Telecommunications Industries, World Economic Forum), “At its core, data represents a post-industrial opportunity. Its uses have unprecedented complexity, velocity and global reach. As digital communications become ubiquitous, data will rule in a world where nearly everyone and everything is connected in real time. That will require a highly reliable, secure and available infrastructure at its core, and innovation at the edge.” Every industry is affected as part of this revolution – also science. An important component of the digital transformation is “trust” – people must be able to trust that governments and all other industries (including the science sector), adequately handle and protect their data. This requires accountability on a global level, and digital industries must embrace the change and go for a higher standard of protection. “This will reassure consumers and citizens, benefitting the whole digital economy”, says Marcus. A stable and secure information and communication technologies (ICT) infrastructure – currently provided by the National Research and Education Networks (NRENs) – is key to advance collaboration in science. The AfricaConnect2 project (AfricaConnect (2012–2014) and AfricaConnect2 (2016–2018)) through establishing connectivity between National Research and Education Networks (NRENs), is planning to roll out AfricaConnect3 by the end of 2019. The concern however is that selected African governments (with the exception of a few countries such as South Africa, Mozambique, Ethiopia and others) have low awareness of the impact the Internet has today on all societal levels, how much ICT (and the 4th Industrial Revolution) have affected research, and the added value an NREN can bring to higher education and research in addressing the respective needs, which is far more complex than simply providing connectivity. Apart from more commitment and investment in R&D, African governments – to become and remain part of the 4th Industrial Revolution – have no option other than to acknowledge and commit to the role NRENs play in advancing science towards addressing the SDG (Sustainable Development Goals). For successful collaboration and direction, it is fundamental that policies within one country are aligned with one another. Alignment on continental level is crucial for the future Pan-African African Open Science Platform to be successful. Both the HIPSSA ((Harmonization of ICT Policies in Sub-Saharan Africa)3 project and WATRA (the West Africa Telecommunications Regulators Assembly)4, have made progress towards the regulation of the telecom sector, and in particular of bottlenecks which curb the development of competition among ISPs. A study under HIPSSA identified potential bottlenecks in access at an affordable price to the international capacity of submarine cables and suggested means and tools used by regulators to remedy them. Work on the recommended measures and making them operational continues in collaboration with WATRA. In addition to sufficient bandwidth and connectivity, high-performance computing facilities and services in support of data sharing are also required. The South African National Integrated Cyberinfrastructure System5 (NICIS) has made great progress in planning and setting up a cyberinfrastructure ecosystem in support of collaborative science and data sharing. The regional Southern African Development Community6 (SADC) Cyber-infrastructure Framework provides a valuable roadmap towards high-speed Internet, developing human capacity and skills in ICT technologies, high- performance computing and more. The following countries have been identified as having high-performance computing facilities, some as a result of the Square Kilometre Array7 (SKA) partnership: Botswana, Ghana, Kenya, Madagascar, Mozambique, Mauritius, Namibia, South Africa, Tunisia, and Zambia. More and more NRENs – especially the Level 6 NRENs 8 (Algeria, Egypt, Kenya, South Africa, and recently Zambia) – are exploring offering additional services; also in support of data sharing and transfer. The following NRENs already allow for running data-intensive applications and sharing of high-end computing assets, bio-modelling and computation on high-performance/ supercomputers: KENET (Kenya), TENET (South Africa), RENU (Uganda), ZAMREN (Zambia), EUN (Egypt) and ARN (Algeria). Fifteen higher education training institutions from eight African countries (Botswana, Benin, Kenya, Nigeria, Rwanda, South Africa, Sudan, and Tanzania) have been identified as offering formal courses on data science. In addition to formal degrees, a number of international short courses have been developed and free international online courses are also available as an option to build capacity and integrate as part of curricula. The small number of higher education or research intensive institutions offering data science is however insufficient, and there is a desperate need for more training in data science. The CODATA-RDA Schools of Research Data Science aim at addressing the continental need for foundational data skills across all disciplines, along with training conducted by The Carpentries 9 programme (specifically Data Carpentry 10 ). Thus far, CODATA-RDA schools in collaboration with AOSP, integrating content from Data Carpentry, were presented in Rwanda (in 2018), and during17-29 June 2019, in Ethiopia. Awareness regarding Open Science (including Open Data) is evident through the 12 Open Science-related Open Access/Open Data/Open Science declarations and agreements endorsed or signed by African governments; 200 Open Access journals from Africa registered on the Directory of Open Access Journals (DOAJ); 174 Open Access institutional research repositories registered on openDOAR (Directory of Open Access Repositories); 33 Open Access/Open Science policies registered on ROARMAP (Registry of Open Access Repository Mandates and Policies); 24 data repositories registered with the Registry of Data Repositories (re3data.org) (although the pilot project identified 66 research data repositories); and one data repository assigned the CoreTrustSeal. Although this is a start, far more needs to be done to align African data curation and research practices with global standards. Funding to conduct research remains a challenge. African researchers mostly fund their own research, and there are little incentives for them to make their research and accompanying data sets openly accessible. Funding and peer recognition, along with an enabling research environment conducive for research, are regarded as major incentives. The landscape report concludes with a number of concerns towards sharing research data openly, as well as challenges in terms of Open Data policy, ICT infrastructure supportive of data sharing, capacity building, lack of skills, and the need for incentives. Although great progress has been made in terms of Open Science and Open Data practices, more awareness needs to be created and further advocacy efforts are required for buy-in from African governments. A federated African Open Science Platform (AOSP) will not only encourage more collaboration among researchers in addressing the SDGs, but it will also benefit the many stakeholders identified as part of the pilot phase. The time is now, for governments in Africa, to acknowledge the important role of science in general, but specifically Open Science and Open Data, through developing and aligning the relevant policies, investing in an ICT infrastructure conducive for data sharing through committing funding to making NRENs financially sustainable, incentivising open research practices by scientists, and creating opportunities for more scientists and stakeholders across all disciplines to be trained in data management.
