A indústria de serviços online é caracterizada por um volume alto de Fusões e Aquisições no período de 2005 a 2015. As líderes de mercado, Apple, Google e Microsoft, incorporaram essa forma de crescimento inorgânico em suas estratégias corporativas. Essa tese examina as atividades de Fusões e Aquisições dessas três empresas. Consequentemente, ela tem foco em dois aspectos principais. Primeiro, existe o objetivo de saciar uma escassez na literatura acadêmica, no que se diz respeito ao estabelecimento de uma conexão entre a estratégia corporativa dessas empresas e as decisões tomadas de Fusões e Aquisições. Segundo, há também o objetivo de estimar possíveis futuros desenvolvimentos no setor. Através de uma análise de conteúdo qualitativa das publicações das empresas, relatórios de análise de mercado, e outros conteúdos de terceiros, estudos de caso foram desenvolvidos. Os resultados mostram o processo de posicionamento estratégico por parte da Apple, Google e Microsoft, dentro do mercado de serviços online, entre os anos de 2005 e 2015. As recorrentes fusões e aquisições são analisadas, no que se diz respeito as estratégias corporativas dessas empresas e a responsividade perante as atividades de seus competidores. Os resultados evidenciam atividades agressivas de Fusões e Aquisições em grupos estratégicos em comum entre as três empresas, especialmente no mercado de aparelhos de comunicação móvel e serviços de comunicação.

Managing server energy and reducing operational cost for online service providers

The past decade has seen the energy consumption in servers and Internet Data Centers (IDCs) skyrocket. A recent survey estimated that the worldwide spending on servers and cooling have risen to above $30 billion and is likely to exceed spending on the new server hardware . The rapid rise in energy consumption has posted a serious threat to both energy resources and the environment, which makes green computing not only worthwhile but also necessary. This dissertation intends to tackle the challenges of both reducing the energy consumption of server systems and by reducing the cost for Online Service Providers (OSPs). Two distinct subsystems account for most of IDC’s power: the server system, which accounts for 56% of the total power consumption of an IDC, and the cooling and humidifcation systems, which accounts for about 30% of the total power consumption. The server system dominates the energy consumption of an IDC, and its power draw can vary drastically with data center utilization. In this dissertation, we propose three models to achieve energy effciency in web server clusters: an energy proportional model, an optimal server allocation and frequency adjustment strategy, and a constrained Markov model. The proposed models have combined Dynamic Voltage/Frequency Scaling (DV/FS) and Vary-On, Vary-off (VOVF) mechanisms that work together for more energy savings. Meanwhile, corresponding strategies are proposed to deal with the transition overheads. We further extend server energy management to the IDC’s costs management, helping the OSPs to conserve, manage their own electricity cost, and lower the carbon emissions. We have developed an optimal energy-aware load dispatching strategy that periodically maps more requests to the locations with lower electricity prices. A carbon emission limit is placed, and the volatility of the carbon offset market is also considered. Two energy effcient strategies are applied to the server system and the cooling system respectively. With the rapid development of cloud services, we also carry out research to reduce the server energy in cloud computing environments. In this work, we propose a new live virtual machine (VM) placement scheme that can effectively map VMs to Physical Machines (PMs) with substantial energy savings in a heterogeneous server cluster. A VM/PM mapping probability matrix is constructed, in which each VM request is assigned with a probability running on PMs. The VM/PM mapping probability matrix takes into account resource limitations, VM operation overheads, server reliability as well as energy effciency. The evolution of Internet Data Centers and the increasing demands of web services raise great challenges to improve the energy effciency of IDCs. We also express several potential areas for future research in each chapter.

Resources and capabilities approach to online strategy – Multiple-case study of Finnish magazines' online services

Most Finnish periodical magazines have a website, often an online service. The objective of this thesis is to understand the magazines’ resources and capabilities and match them with online strategies’ goals and objectives. The thesis’ theoretical part focuses on explaining and classifying resources, capabilities, goals and objectives, and applying everything into Finnish magazine publishing context. In the empirical part, there is a comparative case study of four magazines. The findings indicate that with cooperating, advertising and community hosting capabilities magazines may utilize their human, brand, content and customer base resources. The resources can be further addressed to reach profitability, customer-centricity and brand congruency goals.

The role of network externalities in value creating process of the commercial web service for two-sided international markets

Network externalities and two-sided markets in the context of web services and value creation is not very well discussed topic in academic literature. The explosive rise of the Internet users has created a strong base for many successful web services and pushed many firms towards e-business and online service based business models. Thus the subject of this thesis, the role of network externalities in value creating process of the commer-cial web service for two-sided international markets is very current and interesting topic to examine. The objective of this Master’s Thesis is to advance the study of network externalities from the viewpoint of two-sided markets and network effects as well as describe the value creation & value co-creation process in commercial web service business models. The main proposition suggests that the larger network of customers and the bigger number of users the web service is able to attract, the more value and stronger positive net-work externalities the service is able to create for each customer group. The empirical research of this study was implemented for commercial web service, targeted to Russian consumers and Finnish business users. The findings suggest that the size of the network is highly related to the experi-enced value of the customers and the whole value creation process of commercial web targeted for two-sided international markets varies from the value creation for one-sided or pure domestic markets.

Online data processing consent under EU law: a theoretical framework and empirical evidence from the UK

This article analyses the results of an empirical study on the 200 most popular UK-based websites in various sectors of e-commerce services. The study provides empirical evidence on unlawful processing of personal data. It comprises a survey on the methods used to seek and obtain consent to process personal data for direct marketing and advertisement, and a test on the frequency of unsolicited commercial emails (UCE) received by customers as a consequence of their registration and submission of personal information to a website. Part One of the article presents a conceptual and normative account of data protection, with a discussion of the ethical values on which EU data protection law is grounded and an outline of the elements that must be in place to seek and obtain valid consent to process personal data. Part Two discusses the outcomes of the empirical study, which unveils a significant departure between EU legal theory and practice in data protection. Although a wide majority of the websites in the sample (69%) has in place a system to ask separate consent for engaging in marketing activities, it is only 16.2% of them that obtain a consent which is valid under the standards set by EU law. The test with UCE shows that only one out of three websites (30.5%) respects the will of the data subject not to receive commercial communications. It also shows that, when submitting personal data in online transactions, there is a high probability (50%) of incurring in a website that will ignore the refusal of consent and will send UCE. The article concludes that there is severe lack of compliance of UK online service providers with essential requirements of data protection law. In this respect, it suggests that there is inappropriate standard of implementation, information and supervision by the UK authorities, especially in light of the clarifications provided at EU level.

The Law Applicable to Online Copyright Infringements int ALI and CLIP Proposals: A Rebalance of Interest Needed?

The article discusses the problems of applicable law to copyright infringements online. It firstly identifies the main problems related to the well established territoriality principle and the lex loci protectionis rules. Then; the discussion focuses on the "ubiquitous infringement" rule recently proposed by the American Law Institute (ALI) and the European Max Planck Group for Conflicts of Law and Intellectual Propoperty (CLIP). The author strongly welcomes a compromise between the territoriality and universality approaches suggested in respect of ubiquitous infringement cases. At the same time; the paper draws the attention that the interests of "good faith" online service providers (such as legal certainty and foreseeability) have been until now underestimated and invites to take these interests into account when merging the projects into a common international proposal.

E-service quality:development of a hierarchical model

Using survey data from 358 online customers, the study finds that the e-service quality construct conforms to the structure of a third-order factor model that links online service quality perceptions to distinct and actionable dimensions, including (1) website design, (2) fulfilment, (3) customer service, and (4) security/privacy. Each dimension is found to consist of several attributes that define the basis of e-service quality perceptions. A comprehensive specification of the construct, which includes attributes not covered in existing scales, is developed. The study contrasts a formative model consisting of 4 dimensions and 16 attributes against a reflective conceptualization. The results of this comparison indicate that studies using an incorrectly specified model overestimate the importance of certain e-service quality attributes. Global fit criteria are also found to support the detection of measurement misspecification. Meta-analytic data from 31,264 online customers are used to show that the developed measurement predicts customer behavior better than widely used scales, such as WebQual and E-S-Qual. The results show that the new measurement enables managers to assess e-service quality more accurately and predict customer behavior more reliably.

Qualidade percebida do autosserviço online: validação da escala e-SELFQUAL no contexto brasileiro

Diante de um mercado virtual mais competitivo, impulsionado pelo crescimento das compras online e pelo aumento do número de varejistas nessa modalidade, mensurações para avaliar a qualidade do serviço online tornam-se importantes, sobretudo pela identificação de relação positiva entre a qualidade do serviço e a performance do serviço. Nesse sentido, Ding, Hu e Sheng (2011) propuseram uma medida consistente sobre a qualidade percebida do serviço no comércio eletrônico, sob a perspectiva do autosserviço: e-SELFQUAL. Este artigo apresenta resultados da replicação da e-SELFQUAL no contexto brasileiro. Duas coletas de dados foram realizadas, na primeira, para uma amostra final de 106 estudantes, observou-se uma inadequação em um constructo da escala, e uma nova tradução foi proposta. Uma segunda coleta foi aplicada a uma amostra de 175 pessoas. A confiabilidade e a validade (convergente e discriminante) da escala foram atestadas, mantendo os itens originais do instrumento. Desse modo, os resultados indicam possível uso da e-SELFQUAL para mensurar a qualidade do autosserviço online no Brasil.

Mapping of Chagas disease research: analysis of publications in the period between 1940 and 2009

INTRODUCTION: Publications are often used as a measure of success in research work. Chagas disease occurs in Central and Southern America. However, during the past years, the disease has been occurring outside Latin America due to migration from endemic zones. This article describes a bibliometric review of the literature on Chagas disease research indexed in PubMed during a 70-year period. METHODS: Medline was used via the PubMed online service of the U.S. National Library of Medicine from 1940 to 2009. The search strategy was: Chagas disease [MeSH] OR Trypanosoma cruzi [MeSH]. RESULTS: A total of 13,989 references were retrieved. The number of publications increased steadily over time from 1,361 (1940-1969) to 5,430 (2000-2009) (coefficient of determination for linear fit, R²=0.910). Eight journals contained 25% of the Chagas disease literature. Of the publications, 64.2% came from endemic countries. Brazil was the predominant country (37%), followed by the United States (17.6%) and Argentina (14%). The ranking in production changed when the number of publications was normalized by estimated cases of Chagas disease (Panama and Uruguay), population (Argentina and Uruguay), and gross domestic product (Bolivia and Brazil). CONCLUSIONS: Several Latin American countries, where the prevalence of T. cruzi infection was not very high, were the main producers of the Chagas disease literature, after adjusting for economic and population indexes. The countries with more estimated cases of Chagas disease produced less research on Chagas disease than some developed countries.

SF 2088 Convenience Fees Analysis and Recommendations, November 16, 2011

As an expansion of SF2088, the Department of Administrative Services-Information Technology Enterprise (DAS-ITE) was asked to further analyze the potential costs and savings if the current practice of charging credit card and overhead fees (“value-added fees”) were to be eliminated. Value-added fees reflect the costs an agency incurs while providing online services, and those costs will always exist.. DAS-ITE researched these costs and identified ways of making the associated fees less burdensome to the citizens of Iowa. The three alternatives provide different ways in which agencies can recover those costs; they could be borne by either an annual appropriation or adjustment of the online service “price” to include the fees within the cost of the online transaction. An additional alternative is presented to leave the current value-added fee practices in place. Recognition must also be made of the fact that traditional forms of conducting business with the State of Iowa, face-to-face and paper-based transactions, are inherently more costly. These delivery channels are effectively subsidized by the agency as a “cost of doing business” and the associated expense of the transactions is not passed on to the customer.

Older consumers adopting information and communication technology: Evaluating opportunities for health care applications

The purpose of this dissertation is to analyse older consumers' adoption of information and communication technology innovations, assess the effect of aging related characteristic, and evaluate older consumers' willingness to apply these technologies in health care services. This topic is considered important, because the population in Finland (as in other welfare states) is aging and thus offers a possibility for marketers, but on the other hand threatens society with increasing costs for healthcare. Innovation adoption has been under research from several aspects in both organizational and consumer research. In the consumer behaviour, several theories have been developed to predict consumer responses to innovation. The present dissertation carefully reviews previous research and takes a closer look at the theory of planned behaviour, technology acceptance model and diffusion of innovations perspective. It is here suggested that there is a possibility that these theories can be combined and complemented to predict the adoption of ICT innovations among aging consumers, taking the aging related personal characteristics into account. In fact, there are very few studies that have concentrated on aging consumers in the innovation research, and thus there was a clear indent for the present research. ICT in the health care context has been studied mainly from the organizational point of view. If the technology is thus applied for the communication between the individual end-user and service provider, the end-user cannot be shrugged off. The present dissertation uses empirical evidence from a survey targeted to 55-79 year old people from one city in Southern-Carelia. The empirical analysis of the research model was mainly based on structural equation modelling that has been found very useful on estimating causal relationships. The tested models were targeted to predict the adoption stage of personal computers and mobile phones, and the adoption intention of future health services that apply these devices for communication. The present dissertation succeeded in modelling the adoption behaviour of mobile phones and PCs as well as adoption intentions of future services. Perceived health status and three components behind it (depression, functional ability, and cognitive ability) were found to influence perception of technology anxiety. Better health leads to less anxiety. The effect of age was assessed as a control variable, in order to evaluate its effect compared to health characteristics. Age influenced technology perceptions, but to lesser extent compared to health. The analyses suggest that the major determinant for current technology adoption is perceived behavioural control, and additionally technology anxiety that indirectly inhibit adoption through perceived control. When focusing on future service intentions, the key issue is perceived usefulness that needs to be highlighted when new services are launched. Besides usefulness, the perception of online service reliability is important and affects the intentions indirectly. To conclude older consumers' adoption behaviour is influenced by health status and age, but also by the perceptions of anxiety and behavioural control. On the other hand, launching new types of health services for aging consumers is possible after the service is perceived reliable and useful.

Maksullisen verkkopalvelun konsepti mediayhtiölle

Mediayhtiöt miettivät keinoja joilla saataisiin lukijat maksamaan myös verkkopalveluihin julkaistavista sisällöistä. Tässä tutkimuksessa selvitettiin tilaajapohjaisen maksullisen verkkopalvelu-mallin soveltuvuutta Talentum Media Oy:lle sekä kehitettiin yritykselle maksavia asiakkaita houkuttelevan sisältötuotteen konsepti. Tutkimuksessa ei ilmennyt syitä, joiden takia yrityksen olisi syytä lykätä maksullisen verkkopalvelun kehittämistä. Perinteistä lehteä ja sen verkkopalvelua ei kannata nähdä toistensa kilpailijoina. Käyttäjät ovat yhä valmiimpia maksamaan sisällöstä verkossa, kun se on järjestelty houkutteleviksi kokonaisuuksiksi ja paketoitu oikein, sekä kun he säästävät aikaa tai vaivaa verkkopalvelun käytöllä. Verkkopalvelun muuntaminen maksulliseksi on kuitenkin suunniteltava erittäin tarkkaan, muuten käyttäjät saattavat siirtyä ilmaisiin palveluihin. Talentumin verkkopalveluiden käyttäjille tehdyn kyselytutkimuksen mukaan yrityksen verkkopalveluiden käyttäjät maksaisivat mieluiten verkkokoulutuksista, erityisraporteista ja tutkivasta journalismista, ammattikirjojen tiivistelmistä, opastavista tietopaketeista, pörssi- ja yritystiedosta sekä näköislehdistä. Tutkimuksessa kehitettiin maksullisen verkkopalvelun konsepti, joka tarjoaa lukijoille itsensä kehittämisen välineitä sekä informaatiota nopeasti ja vaivattomasti heidän haluamaansa aikaan ja valitsemallaan päätelaitteella. Konseptia seuraavan tuotekehityshankkeen tuloksena syntyvästä verkkopalvelusta odotetaan saatavan merkittävää lisäliikevaihtoa yrityksen online-toiminnoille.

Aikakauslehden tuttuuden vaikutus halukkuuteen osallistua verkkopalvelun sisällöntuotantoon

Tässä pro gradu -tutkielmassa selvitettiin, miten aikakauslehden eli emobrändin tuttuus vaikuttaa halukkuuteen osallistua verkkopalvelun eli brändilaajennuksen sisällöntuotantoon joukkoistamalla. Kysymys liittyy muuttuneeseen tilanteeseen median kulutuksessa. Teknologia on kehittynyt, paperisten mediatuotteiden kysyntä vähentynyt ja aikakauslehdet kehittävät digitaalisia palvelujaan. Medialla kuitenkaan ole yksinoikeutta sisällöntuotantoon. Kuka tahansa voi tehdä ja julkaista sisältöä. Monet mediat ovat ottaneet lukijat mukaan sisällöntuotantoon. Aiempien tutkimusten perusteella emobrändin tuttuus vaikuttaa myönteisesti asi-akkaiden halukkuuteen käyttää brändilaajennusta. Se vaikuttaa myös ostopäätökseen ja lisää luottamusta verkkopalvelua kohtaan. Tässä tutkimuksessa tuote oli tuttu niille, jotka ovat lehden tilaajia. Lukijalähtöistä sisältöä ovat mm. blogit, verkkokeskustelut, lukijoiden tarinat, runot, kuvat, kilpailut ja kyselyt. Tutkielman aineisto kerättiin verkkokyselyn avulla ja siihen vastasi 437 vastaajaa. Tulosten perusteella emobrändin tuttuus vaikuttaa myönteisesti tilaajien halukkuuteen käyttää aikakauslehden verkkopalvelua. Tilaajat käyvät palvelussa muita käyttäjiä useammin ja osallistuvat tai haluaisivat osallistua ei-tilaajia innokkaammin sisällöntuotantoon. He ovat myös ei-tilaajia kiinnostuneempia lukijalähtöisestä sisällöstä.

Priv-C : une politique de confidentialité personnalisable

Les politiques de confidentialité définissent comment les services en ligne collectent, utilisent et partagent les données des utilisateurs. Bien qu’étant le principal moyen pour informer les usagers de l’utilisation de leurs données privées, les politiques de confidentialité sont en général ignorées par ces derniers. Pour cause, les utilisateurs les trouvent trop longues et trop vagues, elles utilisent un vocabulaire souvent difficile et n’ont pas de format standard. Les politiques de confidentialité confrontent également les utilisateurs à un dilemme : celui d’accepter obligatoirement tout le contenu en vue d’utiliser le service ou refuser le contenu sous peine de ne pas y avoir accès. Aucune autre option n’est accordée à l’utilisateur. Les données collectées des utilisateurs permettent aux services en ligne de leur fournir un service, mais aussi de les exploiter à des fins économiques (publicités ciblées, revente, etc). Selon diverses études, permettre aux utilisateurs de bénéficier de cette économie de la vie privée pourrait restaurer leur confiance et faciliter une continuité des échanges sur Internet. Dans ce mémoire, nous proposons un modèle de politique de confidentialité, inspiré du P3P (une recommandation du W3C, World Wide Web Consortium), en élargissant ses fonctionnalités et en réduisant sa complexité. Ce modèle suit un format bien défini permettant aux utilisateurs et aux services en ligne de définir leurs préférences et besoins. Les utilisateurs ont la possibilité de décider de l’usage spécifique et des conditions de partage de chacune de leurs données privées. Une phase de négociation permettra une analyse des besoins du service en ligne et des préférences de l’utilisateur afin d’établir un contrat de confidentialité. La valeur des données personnelles est un aspect important de notre étude. Alors que les compagnies disposent de moyens leur permettant d’évaluer cette valeur, nous appliquons dans ce mémoire, une méthode hiérarchique multicritères. Cette méthode va permettre également à chaque utilisateur de donner une valeur à ses données personnelles en fonction de l’importance qu’il y accorde. Dans ce modèle, nous intégrons également une autorité de régulation en charge de mener les négociations entre utilisateurs et services en ligne, et de générer des recommandations aux usagers en fonction de leur profil et des tendances.
