Transfer von E-Government-Lösungen : Wirkungen und Strategien / Transfer of e-Government solutions : effects and strategies

Heine, Moreen January 2011 (has links)
Der E-Government-Fortschritt wird nach wie vor durch redundante Entwicklungsaktivitäten und isolierte, wenig interoperable Lösungen gehemmt. Die Herausforderung liegt weniger in der Entwicklung und Einführung leistungsstarker Informationssysteme, sondern in der Verbreitung bestehender Lösungen. Die Arbeit identifiziert mögliche Strategien für den Transfer von E-Government-Lösungen zwischen Verwaltungen gleicher wie auch verschiedener föderaler Ebene. Es werden Konzepte zur Diffusion von Innovationen, zum Technologie- wie auch Politiktransfer herangezogen. Weiter werden drei umfangreiche Fallstudien vorgestellt. Sie führen zu transferhemmenden wie auch fördernden Faktoren und somit zu Gestaltungsoptionen für erfolgreiche Transferprozesse unter den vielfältigen Rahmenbedingungen im öffentlichen Sektor. / The research work on transfer strategies explores ways to spread e-government solutions among public administrations. Studies about diffusion of innovations, technology transfer and policy transfer are used. The work is based on outcomes of three case studies, which lead to obstacles and promoters of transfer processes and hence to design options for successful transfers at diverse conditions within public sector in Germany.

Proactive Privacy Practices in the Trend of Ubiquitous Services: An Empirical Study

Wang, Shu-Ching 02 July 2011 (has links)
Privacy is a strategic issue so that much attention has been constantly devoted to information privacy in response to competitive pressure in dynamic marketplace, particularly in the trend of e-business settings. Ubiquitous services (u-services) are recognized as the logical extension of e-/m-services because they can be initiated by e- and further propagated by m-services (Junglas & Watson 2006). In u-services context, customers are always connected seamlessly in context-awareness networks so the higher degree of customized and personalized services can be timely served. Likewise, customers may also well be aware of privacy threats behind that. Consequently, privacy issues are identified as a key hindrance for booming u-services. While a large body of studies focusing on privacy issues have examined relevant factors influence customer decision making such as customer beliefs (i.e. trust and risk), privacy concerns, the representations of privacy statement, and even the privacy calculus, this study aims to explore a theoretical proactive privacy practice model (PPPM) as a guideline for an e-services provider (ESP) initiating its privacy practices to its customers to enhance voluntary information disclosure. Drawing upon integrative social contracts theory, the proposed PPPM embraced technical and non-technical elements such as human, legal, and economic relevant perspectives, that is, e-services providers¡¦ proactive privacy governance, and customer perceived value and competitive strategies for u-services. An empirical survey was conducted in a B2C e-services context to examine the relationships among these constructs. The results indicate that there are significant relationships between those three antecedents and disclosure willingness respectively. Meanwhile, the moderating effect of competitive strategies significantly and positively associates with proactive privacy governance and disclosure willingness. These findings not only broaden current knowledge of the disclosure behavior but also allow ESPs to strategically manage privacy and leverage privacy protection for a competitive advantage and identify the strengths and weaknesses of their current privacy mechanisms, guiding them to develop more proactive and prominent privacy practices for extending their businesses to future u-services or u-businesses.

Platformisation of the Mobile Services domain in the Open Mobile era : strategic challenges for European Mobile Operators

Passone, Francesco January 2011 (has links)
This research investigates the European Mobile Telecommunications industry, looking at the biggest strategic challenges Mobile Operators are going to face in the next years. Mobile Services platforms represent the most important paradigm in the industry. Companies as Apple, Google and Facebook have successfully married new consumer devices and Internet platforms with a variety of online services and content undermining Operators ́ central role in the value network. This scenario highlights the importance to investigate how Operators can adopt successful strategies to keep on playing a meaningful role in the Mobile Services domain.These strategies are identifies and mapped adopting a value network model for the Mobile Services domain. This model is the main contribution of this research, tracking new ways of cooperating among them. Operators ́ strategies revolve around two main drivers: defeating networks congestion (investing in network upgrade, optimization & spectrum auctions, charging Service Providers for HQ delivery services and elaborating data price plans for mobile customers) and finding new revenue opportunities (working with Service Providers to offer Location-based services, offering charging services to interested parties and working on Mobile Services platforms).As first step, the investigation offers an overview over the industry, looking at static (actors, technologies, services, devices, end-users and value network configuration) as well as dynamic (trends as Open Mobile, MVNOs, Fixed-Mobile Convergence and Substitution and 4G adoption) aspects. Then the research continues analyzing Mobile Services platforms, proposing an interesting approach to classify scientific articles about this topic. Italy is analyzed as case study and subsequently the model is developed. To conclude the study deals with some reflections about the delicate topic of shaping strategies after a massive usage of end-users data to provide innovative and sophisticated mobile services.

Service-Oriented Architecture for the Mobile Cloud Computing / Architecture Orientée Service pour le Mobile Cloud Computing

Houacine, Fatiha 25 November 2016 (has links)
La croissance des appareils connectés, principalement due au grand nombre de déploiements de l'internet des objets et à l'émergence des services de cloud mobile, introduit de nouveaux défis pour la conception d'architectures de services dans le Cloud Computing Mobile (CCM) du cloud computing mobile. Nous montrons dans cette thèse comment l'architecture orientée services SOA peut être une solution clé pour fournir des services cloud mobiles distribués et comment la plate-forme OSGi peut être un cadre adaptatif et efficace pour fournir une telle implémentation. Nous adaptons le cadre CCM proposé à différents contextes d'architecture. Le premier est un modèle centré traditionnel, où les appareils mobiles sont réduits à consommer des services. Le second est un modèle distribué où la puissance de l'interaction de mobile à mobile offre des opportunités illimitées de services de valeur, et enfin, l'architecture à trois niveaux est considérée avec l'introduction de la notion de cloudlet. Pour chaque contexte, nous explorons la performance de notre cadre axé sur le service et le comparons à d'autres solutions existantes. / The growth of connected devices, mostly due to the large number of internet of things IoT deployments and the emergence of mobile cloud services, introduces new challenges for the design of service architectures in mobile cloud computing MCC. An MCC framework should provide elasticity and scalability in a distributed and dynamic way while dealing with limited environment resources and variable mobile contexts web applications, real-time, enterprise services, mobile to mobile, hostile environment, etc. that may include additional constraints impacting the design foundation of cloud services. We show in this thesis how service-oriented architecture SOA can be a key solution to provide distributed mobile cloud services and how OSGi platform can be an adaptive and efficient framework to provide such implementation. We adapt the proposed MCC framework to different architecture contexts. The first one is a traditional centric model, where mobile devices are reduced to consuming services. The second one is a distributed model where the power of mobile-to-mobile interaction offers unlimited value-services opportunities, and finally, three-tier architecture is considered with the introduction of the cloudlet notion. For each context, we explore the performance of our service-oriented framework, and contrast it with alternative existing solutions.

Assessing the m-Government readiness within the provincial government Western Cape

Du Preez, Jacques 03 1900 (has links)
Thesis (MPA (School of Public Management and Planning))--University of Stellenbosch, 2009. / m-Government or mobile-Government is seen as part of e-Government and an additional channel for the delivery of public services and information to the citizen. This study critically examines and evaluates the extent to which the Provincial Government Western Cape has adopted m-Government and implemented related services. A survey conducted by Kirsten (2006) on the adoption and readiness of mobile technology by businesses in South Africa was used as the foundation of this study to determine the level of readiness in the Provincial Government Western Cape. Managers and technical staff within the Province’s information and communication technology component, the Centre for e-Innovation, were interviewed and asked to complete the survey. The study found that, although there is a relatively high degree of adoption with regard to various aspects of mobile and wireless technology, there are many obstacles and barriers that need to be overcome in order to achieve a higher level of m-Government maturity or readiness. The study makes various suggestions on how to overcome these barriers. The most important suggestion is to develop a holistic approach to the adoption of m-Government. Plans for adoption should be incremental to ensure that small victories that can be built on are achieved; the involvement of key stakeholders is also essential.

Community-centric mobile peer-to-peer services: performance evaluation and user studies

Koskela, T. (Timo) 13 November 2011 (has links)
Abstract The popularity of social networking services emphasises the importance of user communities. As the next evolutionary step, social networking will evolve towards user communities that are dynamically established according to contextual aspects such as the shared location and/or activities of people. In this vision, distributed peer-to-peer (P2P) technologies provide a respectable alternative to the centralised client-server technologies for implementing the upcoming community-centric mobile services. This thesis focuses on the development of enabling techniques and methods for a community-centric mobile service environment and on the evaluation of users’ perceptions and user acceptance of novel community-centric mobile services. The research was carried out by first examining the applicability of different P2P system architectures for implementing the management of user communities. Next, an experimental prototype of a community-centric mobile service environment was implemented. The experimental prototype was used for evaluating the performance of the community-centric mobile service environment and for conducting the user studies of novel community-centric mobile services. The evaluation was conducted in a real deployment environment with test users. The main results are the following: (1) a conceptual analysis of the advantages and disadvantages of P2P group management systems that are implemented using architecturally distinct P2P system architectures; (2) a performance evaluation of a P2P community management system, in which each community is implemented as an independent structured P2P overlay network; (3) a novel community-centric mobile service environment and its core component, a mobile middleware, which enables the use of P2P technologies and context information as part of Web-based applications running on a Web browser; (4) an evaluation of users’ perceptions and user acceptance of novel community-centric mobile services that are related to making a selection of an entertainment premise based on its music style and voting for music in a user community. / Tiivistelmä Käyttäjäyhteisöiden tärkeys on korostunut sosiaalista verkottumista edistävien palveluiden suosion kautta. Seuraavaksi sosiaalinen verkottuminen tulee laajentumaan yhteisöihin, jotka perustetaan dynaamisesti muun muassa ihmisten yhteisen sijainnin ja/tai toiminnan perusteella. Tulevaisuuden yhteisöllisten mobiilipalveluiden toteutuksessa hajautetut vertaisverkkoteknologiat tarjoavat varteenotettavan vaihtoehdon keskitetyille asiakas-palvelin -teknologioille. Tämä väitöskirjatyö keskittyy kehittämään tarvittavia tekniikoita ja menetelmiä yhteisöllisen mobiilipalveluympäristön toteuttamiseen sekä arvioimaan käyttäjien kokemuksia uusista yhteisöllisistä mobiilipalveluista.

Relación entre los costos de cambio y el poder de mercado en la industria de telefonía e internet móvil del Perú. / Relationship between switching costs and market power in Peru's cell phone and internet industry

Amancio López, Gianella Evelyn 21 November 2020 (has links)
Este estudio evalúa principalmente el impacto de los costos de cambio en el poder de mercado de las firmas que ofertan los servicios de telefonía e internet móvil (Movistar, Claro, Entel y Vittel), usando datos anuales entre el 2004 y 2019. Primero, se construye el índice de Lerner una medida tradicional de poder de mercado. Para ello, se estima un precio promedio y un costo marginal para cada empresa. Adicionalmente, utilicé el método de Shy para medir los costos de cambio por cada empresa en función del precio promedio y el número de líneas. Luego, dado la disponibilidad de datos panel se aplica la especificación de Generalized Least Squares (GLS) de efectos aleatorios y el modelo de efectos fijos y aleatorios de tiempo. Encontré que los costos de cambio difieren por cada empresa. En la industria de servicios móviles del Perú se encuentra que los costos de cambio más altos corresponden a la empresa Claro y Movistar, pero que en general estos costos de cambio de las empresas se han reducido, lo que sugiere que las políticas regulatorias y la mayor competencia en la industria de servicios móviles han influenciado en su disminución. Asimismo, se encuentra que existe una relación positiva entre los costos de cambio y el poder de mercado. Es decir, las empresas que poseen mayores costos de cambio son las empresas que tienen mayor capacidad para incrementar los precios. Adicionalmente, los resultados sugieren que el poder de mercado se ve afectado por el tamaño de la empresa y el IHH. / This study mainly evaluates the impact of the costs of change on the market power of the firms that offer mobile telephony and internet services (Movistar, Claro, Entel and Vittel), using annual data between 2004 and 2019. First, the Lerner index, a traditional measure of market power, is constructed. To do this, an average price and marginal cost is estimated for each company. Additionally, I used method by Shy method to measure switching costs for each company based on the average price and the number of lines. Then, given the availability of panel data, the Generalized Least Squares (GLS) specification of random effects and the fixed and random effects time model are applied. I found that switching costs differ by company. In Peru's mobile services industry, I found that the highest switching costs are incurred by Claro and Movistar, but that in general these companies' switching costs have been reduced, suggesting that regulatory policies and increased competition in the mobile services industry have influenced their decrease. It is also found that there is a positive relationship between exchange costs and market power. That is, the companies with higher switching costs are the companies that have greater capacity to increase prices. Additionally, the results suggest that market power is affected by company size and HHI. / Trabajo de investigación

Mobile CRM (mCRM) : A CASE STUDY OF MOBILE CRM STRATEGIES

Shaikh, Rehan January 2015 (has links)
Mobile technology has evolved drastically over the years, and so has the customer’s perception of and expectations on mobile services. Mobile phones have become the essential part of customer’s life style and they expect consumer services to be available on mobile phone. In this saturated market, providing better customer experience through the channel preferred by customers is as important as selling the actual product or services. In the quest to retain existing customers as well as attracting new, companies are developing innovative mobile customer relationship management (mCRM) strategies to strike a balance between its investments and fulfilling of customers need to generate maximum profit. However, not all mCRM strategies succeed leaving customers dissatisfied and switching to competitors providing better mobile services. The purpose of this study is to understand the dynamics between the customer acceptance, customer satisfaction and customer loyalty in the context of mCRM services. Thus, answering the following research questions: a) What are the factors behind customer acceptance? b) Do mCRM services have any effect on customer loyalty? Qualitative research method were utilized to closely study two different mCRM strategies from different industries with costumer in focus. Data for the study was gathered from a costumer survey as well as from interviews with informants within the company. In addition, external data from public domain was used to validate the findings of the study. Furthermore, a research model was developed by identifying the constructs adopted from literature study of technology acceptance model (TAM3) and customer loyalty. The research model was the basis for developing the customer feedback survey. In addition, the constructs helped in identifying the impact on customer acceptance and customer loyalty for the respective mCRM strategy. This study confirms previous findings and contributes to our understanding of technology acceptance as well as customer loyalty. The study reveals that mCRM services are mostly useful to urban customers with busy and on-the-go lifestyle. Furthermore, the study shows that through well practice use behavior customer develops a habit based on the prior evaluation of perceived usefulness and perceived value. In addition, the study indicates that customers build up a new trust towards the mCRM services through the usage of the service. Finally, the results of the study indicate that the mCRM services have an impact on company’s net customer loyalty.
