    Living Innovation Laboratory (LIL) is an open and recyclable way for multidisciplinary researchers to remote control resources and co-develop user centered projects. In the past few years, there were several papers about LIL published and trying to discuss and define the model and architecture of LIL. People all acknowledge about the three characteristics of LIL: user centered, co-creation, and context aware, which make it distinguished from test platform and other innovation approaches. Its existing model consists of five phases: initialization, preparation, formation, development, and evaluation. Goal Net is a goal-oriented methodology to formularize a progress. In this thesis, Goal Net is adopted to subtract a detailed and systemic methodology for LIL. LIL Goal Net Model breaks the five phases of LIL into more detailed steps. Big data, crowd sourcing, crowd funding and crowd testing take place in suitable steps to realize UUI, MCC and PCA throughout the innovation process in LIL 2.0. It would become a guideline for any company or organization to develop a project in the form of an LIL 2.0 project. To prove the feasibility of LIL Goal Net Model, it was applied to two real cases. One project is a Kinect game and the other one is an Internet product. They were both transformed to LIL 2.0 successfully, based on LIL goal net based methodology. The two projects were evaluated by phenomenography, which was a qualitative research method to study human experiences and their relations in hope of finding the better way to improve human experiences. Through phenomenographic study, the positive evaluation results showed that the new generation of LIL had more advantages in terms of effectiveness and efficiency.Comment: This is a book draf

    International Taxation in an Era of Digital Disruption: Analyzing the Current Debate

    The “taxation of the digital economy” is currently at the top of the global international tax policymaking agenda. A core claim some European governments are advancing is that user data or user participation in the digital economy justifies a gross tax on digital receipts, new profit attribution criteria, or a special formulary apportionment factor in a future formulary regime targeted specifically at the “digital economy.” Just a couple years ago the OECD undertook an evaluation of whether the digital economy can (or should) be “ring-fenced” as part of the BEPS project, and concluded that it neither can be nor should be. Importantly, concluding that there should be no special rules for the digital economy does not resolve the broader question of whether the international tax system requires reform. The practical reality appears to be that all the largest economies have come to agree either that a) there is something wrong with the taxation of the “digital economy,” or b) there is something more fundamentally wrong with the structure of the current international tax system given globalization and technological trends. This paper is intended as a limited exploration of the second (or third, or fourth) best. It analyzes three policy options that have been discussed in general terms in the current global debate. First, I consider whether “user participation” justifies changing profit allocation results in the digital economy alone. I conclude that applying the user participation concept in a manner that is limited to the digital economy is intellectually indefensible; at most it amounts to mercantilist ring-fencing. Moreover, at the technical level user participation faces all the same challenges as more comprehensive and principled proposals for reallocating excess returns among jurisdictions. Second, I consider one such comprehensive international tax reform idea, loosely referred to by the moniker “marketing intangibles.” This idea represents a compromise between the present transfer pricing system and sales or destination-based reforms to the transfer pricing regime. I conclude that splitting taxing rights over “excess” returns between the present transfer pricing system and a destination-based approach is complex, creates new sources of potential conflict, and requires relatively extensive tax harmonization. This conclusion applies equally to user participation and marketing intangibles. If such a mechanism were nevertheless pursued, I suggest that a formulary system for splitting the excess return is the most manageable approach. Third, I consider “minimum effective taxation” ideas. I conclude that, as compared to the other two policy options discussed herein, minimum effective taxation provides a preferable path for multilateral cooperation

    Achieving a designed customer experience across multiple delivery platforms: A telco perspective

    'Customer experience' is a term that covers a wide range of activities that take place between suppliers and users of products and services. LaSalle and Britton define it as 'a holistic experience which involves a person - as opposed to a customer - as a whole at different levels and in every interaction between such person and a company' (2003). This research considers a key aspect of such an holistic experience: that which is embodied in the product or service under consideration. In the context of increasing mobile technology convergence, the paper considers new approaches that focus on developing the necessary underlying enablers and common interaction flows that are required to deliver a designed experience, taking into account the increasing number of mobile operating systems and service delivery platforms. Ultimately these models move towards allowing users to 'co-create their own unique experiences' (Pralahad and Ramswamy, 2004). The convergence between IT and telecommunications domains presents a unique challenge to product and service designers. Services are increasingly accessible via multiple delivery devices and delivery networks. This trend has been seen most recently in the advent of Internet based services being delivered via mobile phones where 'mobile service delivery and technologies have become the glue between previously secluded 'telecom' and "IT' domains' (Karrberg and Liebenau, 2006). At the same time network operators are trying to tighten their relationship with their customers by offering 'sticky' services aimed at raising the barriers to customer mobility. These two trends lead to a new design challenge: how to design a recognisably consistent and compelling product customer experience that applies over all delivery services, operating systems and networks. Solutions to this problem have to date been either technology led, focussing on integrated delivery platforms, or reliant on rule-based design.

    Remittance flows to post-conflict states: perspectives on human security and development

    Full text link
    This repository item contains a single issue of the Pardee Center Task Force Reports, a publication series that began publishing in 2009 by the Boston University Frederick S. Pardee Center for the Study of the Longer-Range Future.Migrant remittances – that is, money or other goods sent to relatives in the country of origin– play an increasingly central role in post-conflict reconstruction and national development of conflict-affected states. Private remittances are of central importance for restoring stability and enhancing human security in post-conflict countries. Yet the dynamics of conflict-induced remittance flows and the possibilities of leveraging remittances for post-conflict development have been sparsely researched to date. This Pardee Center Task Force Report is the outcome of an interdisciplinary research project organized by the Boston University Center for Finance, Law & Policy, in collaboration with The Frederick S. Pardee Center for the Study of the Longer-Range Future. The Task Force was convened by Boston University development economist John R. Harris and international banking expert Donald F. Terry, and social anthropologist Daivi Rodima-Taylor, Visiting Researcher at the Boston University African Studies Center, served as lead researcher and editor for the report. The Task Force was asked to research, analyze, and propose policy recommendations regarding the role of remittances in post-conflict environments and their potential to serve as a major source of development funds. The report’s authors collectively suggest a broader approach to remittance institutions that provides flexibility to adapt to specific local practices and to make broader institutional connections in an era of growing population displacement and expanding human and capital flows. Conditions for more productive use of migrants’ remittances are analyzed while drawing upon case studies from post-conflict countries in Africa, Asia and Latin America. The papers in this Task Force Report establish the importance of remittances for sustaining local livelihoods as well as rehabilitating institutional infrastructures and improving financial inclusion in post-conflict environments. Highlighting the increasing complexity of global remittance systems, the report examines the growing informality of conflict-induced remittance flows and explores solutions for more efficient linkages between financial institutions of different scales and degrees of formality. It discusses challenges to regulating international remittance transfers in the context of growing concerns about transparency, and documents the increasing role of diaspora networks and migrant associations in post-conflict co-development initiatives. The Task Force Report authors outline the main challenges to leveraging remittances for post-conflict development and make recommendations for further research and policy applications

    Cloud/fog computing resource management and pricing for blockchain networks

    The mining process in blockchain requires solving a proof-of-work puzzle, which is resource expensive to implement in mobile devices due to the high computing power and energy needed. In this paper, we, for the first time, consider edge computing as an enabler for mobile blockchain. In particular, we study edge computing resource management and pricing to support mobile blockchain applications in which the mining process of miners can be offloaded to an edge computing service provider. We formulate a two-stage Stackelberg game to jointly maximize the profit of the edge computing service provider and the individual utilities of the miners. In the first stage, the service provider sets the price of edge computing nodes. In the second stage, the miners decide on the service demand to purchase based on the observed prices. We apply the backward induction to analyze the sub-game perfect equilibrium in each stage for both uniform and discriminatory pricing schemes. For the uniform pricing where the same price is applied to all miners, the existence and uniqueness of Stackelberg equilibrium are validated by identifying the best response strategies of the miners. For the discriminatory pricing where the different prices are applied to different miners, the Stackelberg equilibrium is proved to exist and be unique by capitalizing on the Variational Inequality theory. Further, the real experimental results are employed to justify our proposed model.Comment: 16 pages, double-column version, accepted by IEEE Internet of Things Journa

    How to design browser security and privacy alerts

    Get PDF
    Browser security and privacy alerts must be designed to ensure they are of value to the end-user, and communicate risks efficiently. We performed a systematic literature review, producing a list of guidelines from the research. Papers were analysed quantitatively and qualitatively to formulate a comprehensive set of guidelines. Our findings seek to provide developers and designers with guidance as to how to construct security and privacy alerts. We conclude by providing an alert template, highlighting its adherence to the derived guidelines
