  1. General Classical Electrodynamics.van Vlaenderen Koen - 2016 - Universal Journal of Physics and Application 10 (4):128-140.
    Maxwell’s Classical Electrodynamics (MCED) suffers several inconsistencies: (1) the Lorentz force law of MCED violates Newton’s Third Law of Motion (N3LM) in case of stationary and divergent or convergent current distributions; (2) the general Jefimenko electric field solution of MCED shows two longitudinal far fields that are not waves; (3) the ratio of the electrodynamic energy-momentum of a charged sphere in uniform motion has an incorrect factor of 4/3. A consistent General Classical Electrodynamics (GCED) is presented that is based on (...)

  2. … They don’t really listen to people.Helen Creswick, Liz Dowthwaite, Ansgar Koene, Elvira Perez Vallejos, Virginia Portillo, Monica Cano & Christopher Woodard - 2019 - Journal of Information, Communication and Ethics in Society 17 (2):167-182.
    The voices of children and young people have been largely neglected in discussions of the extent to which the internet takes into account their needs and concerns. This paper aims to highlight young people’s lived experiences of being online.

  3. Accommodation of the Rare Earths in the Periodic Table: A Historical Analysis.Pieter Thyssen & Koen Binnemans - 1978 - In Karl A. Gschneidner Jr, Jean-Claude G. Bünzli & Vitalij K. Pecharsky (eds.), Handbook on the Physics and Chemistry of Rare Earths. Elsevier. pp. 1-93.
    This chapter gives an overview of the evolution of the position of the rare-earth elements in the periodic system, from Mendeleev’s time to the present. Three fundamentally different accommodation methodologies have been proposed over the years. Mendeleev considered the rare-earth elements as homologues of the other elements. Other chemists looked upon the rare earths as forming a special intraperiodic group and therefore clustered the rare-earth elements in one of the groups of the periodic table. Still others adhered to the intergroup (...)

  4. Exploring the integration of business and CSR perspectives in smallholder sourcing: black soybean in Indonesia and tomato in India.Vincent Blok, A. Sjauw-Koen-Fa & O. Omta - 2018 - Journal for Agribusiness in Developing and Emerging Economies 4 (8):656-677.
    Purpose – The purpose of this paper is to assess the impact of smallholder supply chains on sustainable sourcing to answer the question how food and agribusiness multinationals can best include smallholders in their sourcing strategies and take social responsibility for large-scale sustainable and more equitable supply. A sustainable smallholder sourcing model with a list of critical success factors (CSFs) has been applied on two best-practise cases. In this model, business and corporate social responsibility perspectives are integrated. Design/methodology/approach – The (...)

  5. Varieties of wonder: John Wilkins' Mathematical Magic and the perpetuity of invention.Maarten Van Dyck & Koen Vermeir - 2014 - Historia Mathematica 41 (4):463-489.
    Akin to the mathematical recreations, John Wilkins' Mathematicall Magick (1648) elaborates the pleasant, useful and wondrous part of practical mathematics, dealing in particular with its material culture of machines and instruments. We contextualize the Mathematicall Magick by studying its institutional setting and its place within changing conceptions of art, nature, religion and mathematics. We devote special attention to the way Wilkins inscribes mechanical innovations within a discourse of wonder. Instead of treating ‘wonder’ as a monolithic category, we present a typology, (...)

  6. (1 other version)Accessing Online Data for Youth Mental Health Research: Meeting the Ethical Challenges.Elvira Perez Vallejos, Ansgar Koene, Christopher James Carter, Daniel Hunt, Christopher Woodard, Lachlan Urquhart, Aislinn Bergin & Ramona Statache - 2019 - Philosophy and Technology 32 (1):87-110.
    This article addresses the general ethical issues of accessing online personal data for research purposes. The authors discuss the practical aspects of online research with a specific case study that illustrates the ethical challenges encountered when accessing data from Kooth, an online youth web-counselling service. This paper firstly highlights the relevance of a process-based approach to ethics when accessing highly sensitive data and then discusses the ethical considerations and potential challenges regarding the accessing of public data from Digital Mental Health (...)

  7. Selective Optimism About Mind-Uploading.Clas Weber - forthcoming - Journal of Consciousness Studies.
    Optimists about mind-uploading believe that we can survive uploading. Pessimists about mind-uploading, on the other hand, believe that we cannot survive uploading. An under-explored middle ground between the two is a selective form of optimism, which claims that we can survive some forms of uploading, such as gradual replacement uploading, but not others, such as scan-and-copy uploading. Is selective optimism about uploading a rational stance? In this paper I argue that the answer is: yes. The paper has a negative and (...)
