Artifacts are probably our most obvious everyday encounter with technology. Therefore, a good understanding of the nature of technical artifacts is a relevant part of technological literacy. In this article we draw from the philosophy of technology to develop a conceptualization of technical artifacts that can be used for educational purposes. Furthermore we report a small exploratory empirical study to see to what extent teachers’ intuitive ideas about artifacts match with the way philosophers write about the nature of artifacts. Finally, (...) we suggest a teaching and learning strategy for improving teachers’ concepts of technical artifacts through practical activities. (shrink)

We propose simple nonlinear mathematical models for the legal concept of balancing of interests. Our aim is to bridge the gap between an abstract formalisation of a balancing decision while assuring consistency and ultimately legal certainty across cases. We focus on the conflict between the rights to privacy and to the protection of personal data in Art. 7 and Art. 8 of the EU Charter of Fundamental Rights (EUCh) against the right of access to information derived from Art. 11 EUCh. (...) These competing rights are denoted by ( \(i_1\) ) _right to privacy _ and ( \(i_2\) ) _access to information_; mathematically, their indices are respectively assigned by \(u_1\in [0,1]\) and \(u_2\in [0,1]\) subject to the constraint \(u_1+u_2=1\). This constraint allows us to use one single index _u_ to resolve the conflict through balancing. The outcome will be concluded by comparing the index _u_ with a prior given threshold \(u_0\). For simplicity, we assume that the balancing depends on only selected legal criteria such as the social status of affected person, and the sphere from which the information originated, which are represented as inputs of the models, called legal parameters. Additionally, we take “time” into consideration as a legal criterion, building on the European Court of Justice’s ruling on the right to be forgotten: by considering time as a legal parameter, we model how the outcome of the balancing changes over the passage of time. To catch the dependence of the outcome _u_ by these criteria as legal parameters, data were created by a fully-qualified lawyer. By comparison to other approaches based on machine learning, especially neural networks, this approach requires significantly less data. This might come at the price of higher abstraction and simplification, but also provides for higher transparency and explainability. Two mathematical models for _u_, a time-independent model and a time-dependent model, are proposed, that are fitted by using the data. (shrink)

This paper discusses the uniqueness thesis, a core thesis in the epistemology of disagreement. After presenting uniqueness and clarifying relevant terms, a novel counterexample to the thesis will be introduced. This counterexample involves logical disagreement. Several objections to the counterexample are then considered, and it is argued that the best responses to the counterexample all undermine the initial motivation for uniqueness.

This paper aims to show that Selim Berker’s widely discussed prime number case is merely an instance of the well-known generality problem for process reliabilism and thus arguably not as interesting a case as one might have thought. Initially, Berker’s case is introduced and interpreted. Then the most recent response to the case from the literature is presented. Eventually, it is argued that Berker’s case is nothing but a straightforward consequence of the generality problem, i.e., the problematic aspect of the (...) case for process reliabilism (if any) is already captured by the generality problem.

This article is an investigation of parallel themes in Heinrich Hertz's philosophy science and Kant's theory of schemata, symbols and regulative ideas. It is argued that Hertz's "pictures" bears close similarities to Kantian "schemata", that is, they are rules linking concepts to intuitions and provide them with their meaning. Kant's distinction between symbols and schemata is discussed and related to Hertz's three pictures of mechanics. It is argued that Hertz considered his own picture of mechanics as symbolic in a different (...) way than the force and energy pictures. In the final part of the article it is described how Harald Høffding soon after the publication of Hertz's Principles of Mechanics developed a general theory of analogical reasoning, relying on the ideas of Hertz and Kant.

BackgroundThe preferable position of Deep Brain Stimulation electrodes is proposed to be located in the dorsolateral subthalamic nucleus to improve general motor performance. The optimal DBS electrode localization for the post-operative improvement of balance and gait is unknown.MethodsIn this single-center, retrospective analyses, 66 Parkinson’s disease patients were assessed pre- and post-operatively by using MDS-UPDRS, freezing of gait score, Giladi’s gait and falls questionnaire and Berg balance scale. The clinical outcome was related to the DBS electrode coordinates in x, y, z (...) plane as revealed by image-based reconstruction. Binomial generalized linear mixed models with fixed-effect variables electrode asymmetry, parkinsonian subtype, medication, age class and clinical DBS induced changes were analyzed.ResultsSubthalamic nucleus-deep brain stimulation improved all motor, balance and FoG scores in MED OFF condition, however there were heterogeneous results in MED ON condition. DBS electrode reconstructed coordinates impacted the responsiveness of axial symptoms. FoG and balance responders showed slightly more medially located STN electrode coordinates and less medio-lateral asymmetry of the electrode reconstructed coordinates across hemispheres compared to non-responders.ConclusionDeep brain stimulation electrode reconstructed coordinates, particularly electrode asymmetry on the medio-lateral axis affected the post-operative responsiveness of balance and FoG symptoms in PD patients.

We characterise the intermediate logics which admit a cut-free hypersequent calculus of the form \, where \ is the hypersequent counterpart of the sequent calculus \ for propositional intuitionistic logic, and \ is a set of so-called structural hypersequent rules, i.e., rules not involving any logical connectives. The characterisation of this class of intermediate logics is presented both in terms of the algebraic and the relational semantics for intermediate logics. We discuss various—positive as well as negative—consequences of this characterisation.

Recent data have provided evidence for an unrecognised ancient lineage of green plants that persists in marine deep-water environments. The green plants are a major group of photosynthetic eukaryotes that have played a prominent role in the global ecosystem for millions of years. A schism early in their evolution gave rise to two major lineages, one of which diversified in the world's oceans and gave rise to a large diversity of marine and freshwater green algae (Chlorophyta) while the other gave (...) rise to a diverse array of freshwater green algae and the land plants (Streptophyta). It is generally believed that the earliest-diverging Chlorophyta were motile planktonic unicellular organisms, but the discovery of an ancient group of deep-water seaweeds has challenged our understanding of the basal branches of the green plant phylogeny. In this review, we discuss current insights into the origin and diversification of the green plant lineage. (shrink)

With the help of key normative concepts borrowed from social epistemology and work on epistemic duties and norms of justification we want to clarify what is at the core of learning mediated through testimony. In socially networked professional contexts, assessment of the epistemic reliability of networked information is important: justification of knowledge acquired via the word of others has an intrinsic social and normative dimension. Whereas the former has been largely taken into account in today’s learning theories based on social (...) constructivism and connectivism, the normative dimension of justification is very much overlooked. The enormous wealth of information on the internet, the myriad of seemingly contradictory statements and the distance that powerful media create between the information spread and the direct access to the facts and first-hand experience, poses challenges to learning theorists who want to formulate solid foundations for e-learning. This has led many to adopt theories, like socio-constructivism and connectivism, which put less focus on truth, accuracy and truthfulness in an effort to cope with dissenting opinions. We will argue that shying away from truthfulness as a central ingredient of learning is mistaken. You can have the benefits from today’s e-learning theories without committing to the fallacies of relativism or constructivism. (shrink)

This moral philosophy text with readings embraces Socrates' observation that ethics is "no small matter, but how we ought to live." How ought we to live? This hard question captures the full range of moral inquiry from traditional moral theory to contemporary moral issues, such as abortion, capital punishment, and war. But there is much more to moral philosophy: How should we be as people? When should we forgive? Are we capable of morality? What about non-western ethics? And most distressing (...) of all, why be moral in the first place? These and other challenging questions show the profundity and inescapable importance of moral philosophy for a life worth living. Life's Hardest Questions combines lively and informative introductory discussions with classic and contemporary writings in moral philosophy. (shrink)

SUMMARYThe history of the law of nations is generally seen as a synonym for the history of the laws of war. Yet, a strictly bilateral perspective can distort our interpretation of early modern diplomacy. The Peace of Utrecht inaugurated an era of relative stability in the European state system, based on balance-of-power politics and anti-hegemonic legal argumentation. Incidental conflicts ought to be interpreted against this background. Declarations of war issued in 1718, 1719 and 1733 during the War of the Quadruple (...) Alliance and the Polish Succession should not be read as doctrinal surrogates for trials between two parties, but as manifestos in a European arena. (shrink)

The paper gives a detailed reconstruction and discussion of Peirce’s doctrine of propositions, so-called Dicisigns, developed in the years around 1900. The special features different from the logical mainstream are highlighted: the functional definition not dependent upon conscious stances nor human language, the semiotic characterization extending propositions and quasi-propositions to cover prelinguistic and prehuman occurrences of signs, the relations of Dicisigns to the conception of facts, of diagrammatical reasoning, of icons and indices, of meanings, of objects, of syntax in Peirce’s (...) logic-as-semiotics.

Precisamos repensar a nossa abordagem quanto à proteção da privacidade na internet. Atualmente, os formuladores de políticas vêm se aprofundando na ideia de consentimento informado como um meio para proteger a privacidade. Por exemplo, em diversos países, as empresas são obrigadas por lei a obter o consentimento de um indivíduo antes de fazer uso dos seus dados; com base nessas requisitos de consentimento informado, a lei tem por objetivo empoderar as pessoas a fazerem escolhas de privacidade tendo em vista os (...) seus melhores interesses. No entanto, estudos comportamentais colocam em cheque a eficácia desta abordagem de empoderamento como um meio para proteger a privacidade. Este artigo defende uma abordagem conjunta de proteção e empoderamento dos indivíduos para aprimorar a proteção da privacidade. Este artigo aborda problemas práticos do consentimento informado como um meio para proteger a privacidade, e ilustra problemas com os atuais regulamentos de proteção à privacidade dos dados, concernentes à segmentação comportamental. Primeiramente, discutem-se os problemas de privacidade relativos à segmentação comportamental, e o papel central do consentimento informado ao abrigo da lei de proteção à privacidade. Em seguida, enfatizam-se os problemas práticos referentes ao consentimento informado. Por fim, o artigo argumenta que os formuladores de políticas devem dar mais atenção aos regulamentos que protegem as pessoas, e menos aos que as empoderam. INFORMED CONSENT: WE CAN DO BETTER TO DEFEND PRIVACYAbstractWe need to rethink our approach to defend privacy on the internet. Currently, policymakers focus heavily on the idea of informed consent as a means to defend privacy. For instance, in many countries the law requires firms to obtain an individual’s consent before they use data about her. With such informed consent requirements, the law aims to empower people to make privacy choices in their best interests. But behavioural studies cast doubt on this approach’s effectiveness, as people tend to click OK to almost any request they see on their screens. To improve privacy protection, this article argues for a combined approach of protecting and empowering the individual. (shrink)
