    Widespread e-commerce activity on the Internet has led to new opportunities to collect vast amounts of micro-level market and nonmarket data. In this paper we share our experiences in collecting, validating, storing and analyzing large Internet-based data sets in the area of online auctions, music file sharing and online retailer pricing. We demonstrate how such data can advance knowledge by facilitating sharper and more extensive tests of existing theories and by offering observational underpinnings for the development of new theories. Just as experimental economics pushed the frontiers of economic thought by enabling the testing of numerous theories of economic behavior in the environment of a controlled laboratory, we believe that observing, often over extended periods of time, real-world agents participating in market and nonmarket activity on the Internet can lead us to develop and test a variety of new theories. Internet data gathering is not controlled experimentation. We cannot randomly assign participants to treatments or determine event orderings. Internet data gathering does offer potentially large data sets with repeated observation of individual choices and action. In addition, the automated data collection holds promise for greatly reduced cost per observation. Our methods rely on technological advances in automated data collection agents. Significant challenges remain in developing appropriate sampling techniques integrating data from heterogeneous sources in a variety of formats, constructing generalizable processes and understanding legal constraints. Despite these challenges, the early evidence from those who have harvested and analyzed large amounts of e-commerce data points toward a significant leap in our ability to understand the functioning of electronic commerce.Comment: Published at http://dx.doi.org/10.1214/088342306000000231 in the Statistical Science (http://www.imstat.org/sts/) by the Institute of Mathematical Statistics (http://www.imstat.org

    Collective Action and Social Innovation in the Energy Sector: A Mobilization Model Perspective

    Get PDF
    This conceptual paper applies a mobilization model to Collective Action Initiatives (CAIs) in the energy sector. The goal is to synthesize aspects of sustainable transition theories with social movement theory to gain insights into how CAIs mobilize to bring about niche-regime change in the context of the sustainable energy transition. First, we demonstrate how energy communities, as a representation of CAIs, relate to social innovation. We then discuss how CAIs in the energy sector are understood within both sustainability transition theory and institutional dynamics theory. While these theories are adept at describing the role energy CAIs have in the energy transition, they do not yet offer much insight concerning the underlying social dimensions for the formation and upscaling of energy CAIs. Therefore, we adapt and apply a mobilization model to gain insight into the dimensions of mobilization and upscaling of CAIs in the energy sector. By doing so we show that the expanding role of CAIs in the energy sector is a function of their power acquisition through mobilization processes. We conclude with a look at future opportunities and challenges of CAIs in the energy transition.This research was conducted under the COMETS (Collective action Models for Energy Transition and Social Innovation) project, funded by the Horizon 2020 Framework Program of the European Commission, grant number 837722

    The political dimension of animal ethics in the context of bioethics: problems of integration and future challenges

    Get PDF
    Animal ethics has reached a new phase with the development of animal ethical thinking. Topics and problems previously discussed in terms of moral theories and ethical concepts are now being reformulated in terms of political theory and political action. This constitutes a paradigm shift for Animal Ethics. It indicates the transition from a field focused on relations between individuals (humans and animals) to a new viewpoint that incorporates the political dimensions of the relationships between human communities and non-human animals. Animals are no longer seen as a heterogeneous group of sentient beings or simply as species, but as part of a common good that is simultaneously human and animal. In order to participate in this new phase, bioethics will have to face a series of challenges that have hindered the integration of animal ethics within its field. It will also need the development of a new theoretical framework based on relations between communities of individuals. This framework will be able to highlight the ethical and political dimensions that arise from interactions between human communities, non-human animals and the ecosystem

    Justice and predictability in torts

    Get PDF
    Recent reexaminations of the principles of tort liability have entertained two possible rationales for the fault principle, one "moral" and the other economic. Neither is satisfactory. I propose here a third rationale and show how it suffices to refute at least some of the challenges to the negligence system. The character of this rationale is causal, and the central thesis of this paper is that in as much as the tort system should aim to place the costs of accidents on the source of those accidents, then we have not yet found an acceptable alternative to the negligence system. This thesis is defended and developed through a reexamination of some recent theories of strict liability and reflection on some of what has been said about the role of causation in torts. A backdrop to the entire discussion is the question of how one might best ensure that potential defendants will be able to predict with reasonable certainty which courses of action will make them liable, should damages ensue

    e‑Learning Success Model: An Information Systems Perspective

    Get PDF
    This paper reports the observations made and experience gained from developing and delivering an online quantitative methods course for Business undergraduates. Inspired by issues and challenges experienced in developing the online course, a model is advanced to address the question of how to guide the design, development, and delivery of successful e‑learning initiatives based on theories of a user‑centered information systems development paradigm. The benefits of using the proposed model for e‑learning success assessment is demonstrated through four cycles of action research after two action research cycles of pilot study. Findings from our empirical study confirm the value of an action research methodology for promoting e‑learning success. The paper concludes with a discussion on the merits of the proposed model in furthering our understanding of how to define, assess, and promote e‑learning success

    Networks as perspective on policy and implementation

    This article discusses the jungle of theories and approaches that abound today in works applied to the management of relations between organizations. It discusses the actions of 'individuals' who may be thought of as managers of an inter-organizational entity (IOE). It also explores research that describes organizational capabilities - in the sense of building them - as a product of, and an enactment through, managerial action. It address the various ways in which this kind of research has been conducted, including a discussion of the various methodologies and underlying theories that provide foundations for discussions of the management challenges inherent in dealing with collaboration and areas of substantive focus. Finally, this article closes with a discussion of significant gaps in the literature that require future research.</p

    Applying Deweyan Principles to Global Citizenship Education in a Rural Context

    Get PDF
    Abstract Global citizenship education (GCE) helps students conceptualize citizenship beyond national boundaries so they are capable of action in dealing with global issues like human rights and environmental sustainability. However, very little literature exists to assist rural teachers in implementing GCE as they face specific challenges due to the context of their schools. This paper identifies challenges rural educators encounter, such as conservative communities and geographic isolation, and details a Deweyan approach to GCE as a means to overcome these challenges. Specifically, we apply Dewey’s democratic and social learning theories to reconceptualize GCE around student, family, and community life to foster a more relevant curriculum that utilizes students’ experiences (Dewey, 1897, 1902, 1938, 1916/2008). It emphasizes the utmost respect for local customs and culture by using them as sources of content for the curriculum while simultaneously extending citizenship thoughts and actions to the global arena.

    Photovoice: Community-based research in Bluefields, Jamaica

    Get PDF
    Participatory action research (PAR) approaches to community intervention have demonstrated to be helpful in addressing and identifying community strengths and challenges, along with leading members of a community into action. Photovoice is a qualitative method of community-based participatory action research (CBPR) by which members of a community create and discuss photographs as a means of facilitating personal and community change. While much research using Photovoice has been conducted in rural areas of China and Africa, no research of this type has been found in rural Jamaica. This study implemented PAR research using the CBPR method of Photovoice in the rural community of Bluefields, Jamaica, utilizing social work theories of strength, advocacy and empowerment. Four distinct themes were identified in this study: sustainability, preservation, education, and community. Implications for community social work research and practice are discussed

    Legal Pluralism in Tort Law Theory: Balancing Instrumental Theories and Corrective Justice

    Get PDF
    Unified-monistic theories of tort law focus on a single goal, usually corrective justice, distributive justice, or optimal deterrence. Unlike these approaches, mixedpluralistic theories attempt to balance between various goals of tort law by integrating several of the considerations underlying these different goals. These theories of legal pluralism reflect ideological diversity, in this case between different theories of the same legal system. This Article discusses the challenge of legal pluralism to settle the possible collision between different goals of tort law within the framework of tort law theory. Starting from a position of support for the mixed-pluralistic thesis, this Article first identifies the advantages this approache offers and then proposes a new mixedpluralistic approach which is adapted to the multitude of significant changes that have affected contemporary common tort law in recent years. This new approach divides (mostly negligence) issues into two principal categories based on the profile of the defendant and the nature of his tortious act, striking a balance between the various goals of tort law, as the situation warrants. Thus, the suggested mixedpluralistic approach offers a new and actual balance between corrective justice and instrumental theories—that is, distributive justice and optimal deterrence. It balances between deontological theories, which are interested in the moral aspect of a tort action, and utilitarian theories, which are interested in the consequentialist outcome of a tort action. The proposed approach will be implemented through the presentation of a number of tort issues, some traditional and classic and others modern and novel. The suggested approach challenges the study of both law and economics and corrective justice by trying to delimit their dominance as sole goals. It also corresponds with other pluralistic approaches to the study of torts
