A Survey of Green Networking Research

Reduction of unnecessary energy consumption is becoming a major concern in wired networking, because of the potential economical benefits and of its expected environmental impact. These issues, usually referred to as "green networking", relate to embedding energy-awareness in the design, in the devices and in the protocols of networks. In this work, we first formulate a more precise definition of the "green" attribute. We furthermore identify a few paradigms that are the key enablers of energy-aware networking research. We then overview the current state of the art and provide a taxonomy of the relevant work, with a special focus on wired networking. At a high level, we identify four branches of green networking research that stem from different observations on the root causes of energy waste, namely (i) Adaptive Link Rate, (ii) Interface proxying, (iii) Energy-aware infrastructures and (iv) Energy-aware applications. In this work, we do not only explore specific proposals pertaining to each of the above branches, but also offer a perspective for research.Comment: Index Terms: Green Networking; Wired Networks; Adaptive Link Rate; Interface Proxying; Energy-aware Infrastructures; Energy-aware Applications. 18 pages, 6 figures, 2 table

Market acceptance of cloud computing: An analysis of market structure, price models and service requirements

Diese Arbeit betrachtet menschliches Verhalten auf elektronischen Märkten. In diesem Zusammenhang wurden zwei Experimente durchgeführt, die das Auction Fever in Holländischen Auktionen sowie das menschliche Risikoverhalten im sehr hohen Wahrscheinlichkeitsbereich näher untersuchen. Im Experiment zum menschlichen Risikoverhalten wurde speziell die Bewertung hoher Gewinnwahrscheinlichkeiten durch die Teilnehmer untersucht. Hinsichtlich des Auction Fever wurde ein Referenzexperiment beschrieben, kritisiert und auf Basis dieser Kritik ein Folgeexperiment durchgeführt. Hierbei wurde beobachtet, dass Menschen ein vorher gesetztes Limit nicht konstant unterbieten sondern auch teilweise überbieten. Es wurden außerdem Einflussfaktoren für diesen emotionalen Effekt erarbeitet. --Verhandlungstheorie,Experiment

Electronic market as a strategic lever of an innovation virtual system - an integrative approach to territorial innovations management

During the last years, electronic market has become established very quickly in all areas of the business world. Moreover, according to the most recent forecasts, it will grow exponentially during the years. ?Electronic market? phenomenon highlights the most significant effect of the Information and Communication Technologies development: space and time independence of the economic and social processes; every people, every social group, every Organization can communicate or can share information, knowledge, objectives, anywhere and anytime. In this new socioeconomic context, a re-thinking of local system economic growth models becomes necessary. In this paper we present Innovation Virtual System, as a new model for local systems development. Innovation System is conceived as a set of interacting Organizations, embedded in a dense web of social and economic relationships, skilled at creating, acquiring and transferring knowledge and at adapting their behavior according to knowledge about their external and internal settings. More specifically, we try to identify the effects of electronic market on these ?knowledge creating? Organizations, that is on their internal learning circuits and on their external relationships. Particularly we focus in the Internet based electronic market, highlighting the differences between Internet and the previous computing and communication environment, in order to give a clearer understanding of Internet as the strategic infrastructure of electronic market. After describing the impact of the Internet based electronic market on a single Organization, we present a framework of a local system collective learning process, and we describe some of the opportunities offered by the Internet based electronic market to this process.

Tourism and Simulacrum: The Computational Economy of Algorithmic Destinations

AbstractThe paper establishes a conceptual and methodological link between destinations and simulacrum through gamified tourism. As a paradigm, gamified tourism provides a rationale and a setting within which to apply computational economics to tourism, an approach amounting to tourism computability. Algorithmic destinations serve as “petri dishes” for real destinations. Utilizing rule sets that embody destination growth dynamics and visitor behavioural norms, seeding points in a cellular automata model (CA) were grown into algorithmic destinations. This is followed by a morphological transformation of geo-tagged satellite images into spatial points. The overlap of this additive and subtractive approach is at the core of tourism computability. Finally, the spatio-temporal dynamics of economic resilience was traced out through a visual phenomenology of algorithmic destinations. The gamification of tourism should be embraced as it holds up a flicker of hope for mature destinations, amidst the onset of museumification and increased commoditization of heritage sites. Gamification is treated as part of the reflexive cycle for destination authenticity; a notion that that Cohen (1988) alluded to in his discussion of emergent authenticity in destination image formation. Seen in this light, the museumification of Venice and the proliferation of its simulacrum, such as the Venetian Hotel in Macao and Venice-themed hotels across the globe, are prefigures and archetypes of a glorious age of gamified tourism

Social, administrative and educational dimensions of the “human – subject of economic life” phenomenon under conditions of information society transition to a new level of development

Перехід інформаційного суспільства на новий рівень розвитку в тріаді генезисних процесів «становлення – формування – розвиток» спричинює численні зміни. Серед них: становлення суспільства знань; інтенсивний розвиток інформаційного простору задіянням ресурсів активного інформаційного простору, неактивного інформаційного простору майбутнього та неактивного інформаційного простору минулого; становлення рольового призначення людини як трудового потенціалу і людського капіталу. Ці зміни актуалізують процеси формування та розвитку людини-суб’єкта економічного життя. Розгляд цих процесів у суспільному, управлінському та освітньому вимірах дає можливість виокремити низку домінант сучасності. Це зростаючо-домінуюча роль комп’ютерної комунікації. Спрямування управління на поєднання інтересів окремих людей з інтересами організації та її стратегічними цілями. Задіяння соціального управління як менеджменту людських ресурсів. Розвиток людини як особистості. Формування та розвиток ІК-компетентності в системі неперервної освіти.Переход информационного общества на новый уровень развития в триаде генезисних процессов «становление – формирование – развитие» вызывает многочисленные изменения. Среди них: становление общества знаний; интенсивное развитие информационного пространства задействованием ресурсов активного информационного пространства, неактивного информационного пространства будущего и неактивного информационного пространства прошлого; становления ролевого назначения человека как трудового потенциала и человеческого капитала. Эти изменения актуализируют процессы формирования и развития человека-субъекта экономической жизни. Рассмотрение этих процессов в общественной, управленческом и образовательном измерениях дает возможность выделить ряд доминант современности. Это растущая и доминирующая роль компьютерной коммуникации. Направление управления на сосотнесение интересов отдельных людей с интересами организации и ее стратегическими целями. Задействования социального управления как менеджмента человеческих ресурсов. Развитие человека как личности. Формирование и развитие ИК-компетентности в системе непрерывного образования.The information society transition to a new level of development in the triad of genesis processes of "incipience – formation – development" causes a lot of changes: the formation of a knowledge society; intensive development of the information space by using the resources of the active information space, the inactive information space of the future and the inactive information space of the past; formation of person’s purpose as labor potential and human capital. These changes actualize the processes of formation and development of the human as subject of economic life. Consideration of these processes in the social, administrative and educational dimensions makes it possible to single out a number of dominant features of the present – it is the growing dominant role of computer communication; management focusing on combining the interests of individuals with the interests of the organization and its strategic goals is important; engaging social management as human resource management; personal development of human; formation and development of IСT competence in the system of continuous education

Designing the business models for circular economy : towards the conceptual framework

Switching from the current linear model of economy to a circular one has recently attracted increased attention from major global companies e.g., Google, Unilever, Renault, and policymakers attending the World Economic Forum. The reasons for this are the huge financial, social and environmental benefits. However, the global shift from one model of economy to another also concerns smaller companies on a micro-level. Thus, comprehensive knowledge on designing circular business models is needed to stimulate and foster implementation of the circular economy. Existing business models for the circular economy have limited transferability and there is no comprehensive framework supporting every kind of company in designing a circular business model. This study employs a literature review to identify and classify the circular economy characteristics according to a business model structure. The investigation in the eight sub-domains of research on circular business models was used to redefine the components of the business model canvas in the context of the circular economy. Two new components - the take-back system and adoption factors - have been identified, thereby leading to the conceptualization of an extended framework for the circular business model canvas. Additionally, the triple fit challenge has been recognized as an enabler of the transition towards a circular business model. Some directions for further research have been outlined, as well

Infrastructure-as-a-Service Usage Determinants in Enterprises

The thesis focuses on the research question, what the determinants of Infrastructure-as-a-Service usage of enterprises are. A wide range of IaaS determinants is collected for an IaaS adoption model of enterprises, which is evaluated in a Web survey. As the economical determinants are especially important, they are separately investigated using a cost-optimizing decision support model. This decision support model is then applied to a potential IaaS use case of a large automobile manufacturer
