The Turing Test is of limited use for entities differing substantially from human performance levels. We suggest an extension of Turing’s idea to a more differentiated measure - the "Turing Ratio" - which provides a framework for comparing human and algorithmic task performance, up to and beyond human performance levels. Games and talent levels derived from pairwise comparisons provide examples of the concept. We also discuss the related notions of intelligence amplification and task breadth. Intelligence amplification measures total computational efficiency (...) (the computational benefit gained relative to investment, including programmer time, hardware, and so on); we argue that evolutionary computation is a key amplifier of human intelligence. Task breadth is an attempt to weight Turing Ratios by the frequency and importance of the task they measure - doing well at a broad range of tasks is an empirical definition of “intelligence”. Measuring Turing Ratios and considering task breadth, prior knowledge, and time series of the measures may yield long-term insight into both open-ended computational approaches and the underlying task domains being measured.

Ethical approval must be obtained before medical research can start. We describe the differences in EA for an pseudonymous, non-interventional, observational European study. Sixteen European national coordinators of the international study on very old intensive care patients answered an online questionnaire concerning their experience getting EA. N = 8/16 of the NCs could apply at one single national ethical committee, while the others had to apply to various regional ECs and/or individual hospital institutional research boards. The time between applying for (...) EA and the first decision varied between 7 days and 300 days. In 9/16 informed consent from the patient was not deemed necessary; in 7/16 informed consent was required from the patient or relatives. The upload of coded data to a central database required additional information in 14/16. In 4/16 the NCs had to ask separate approval to keep a subject identification code list to de-pseudonymize the patients if questions would occur. Only 2/16 of the NCs agreed that informed consent was necessary for this observational study. Overall, 6/16 of the NCs were satisfied with the entire process and 8/16 were unsatisfied. 11/16 would welcome a European central EC that would judge observational studies for all European countries. Variations in the process and prolonged time needed to get EA for observational studies hampers inclusion of patients in some European countries. This might have a negative influence on the external validity. Further harmonization of ethical approval process across Europe is welcomed for low-risk observational studies. Getting ethical approval for low-risk, non-interventional, observational studies varies enormously across European countries. (shrink)

Little is known about research misconduct within industry and how it compares to universities, even though a lot of biomedical research is performed by–or in collaboration with–commercial entities. Therefore, we sent an e-mail invitation to participate in an anonymous computer-based survey to all university researchers having received a biomedical research grant or scholarship from one of the two national academic research funders of Belgium between 2010 and 2014, and to researchers working in large biomedical companies or spin-offs in Belgium. The (...) validated survey included questions about various types of research misconduct committed by respondents themselves and observed among their colleagues in the last three years. Prevalences of misconduct were compared between university and industry respondents using binary logistic regression models, with adjustments for relevant personal characteristics, and with significance being accepted for p < 0.01. The survey was sent to 1766 people within universities and an estimated 255 people from industry. Response rates were 43 and 48%, and usable information was available for 617 and 100 respondents, respectively. In general, research misconduct was less likely to be reported by industry respondents compared to university respondents. Significant differences were apparent for one admitted action and three observed actions, always with lower prevalences for industry compared to universities, except for plagiarism. This survey, based on anonymous self-report, shows that research misconduct occurs to a substantial degree among biomedical researchers from both industry and universities. (shrink)

The aim of the article is to theoretically develop a notion of digital _Bildung_ that accepts the “world” of today as characterised by the entanglement of humans and technology. I draw on Adorno’s critical notion of _Bildung_, Luciano Floridi’s and Katherine Hayles’ respective understandings of the human-technology entanglement, and the social philosophy of the American philosopher Robert Brandom to understand _Bildung_ as a piecemeal process. Nevertheless, _Bildung_ is a rational process of making explicit the implicit connections to which we commit (...) ourselves by being entangled in a tech–non-tech world. The article contributes to delineating a theoretical notion of digital _Bildung_ that accepts and develops _Bildung_ as critically precipitating from within this entanglement—what Brandom terms a semantic self-consciousness.

Sterelny's Thought in a Hostile World ([2003]) presents a complex, systematically structured theory of the evolution of cognition centered on a concept of decoupled representation. Taking Godfrey-Smith's ([1996]) analysis of the evolution of behavioral flexibility as a framework, the theory describes increasingly complex grades of representation beginning with simple detection and culminating with decoupled representation, said to be belief-like, and it characterizes selection forces that drive evolutionary transformations in these forms of representation. Sterelny's ultimate explanatory target is the evolution of (...) human agency. This paper develops a detailed analysis of the main cognitive aspects. It is argued that some of the major claims are not correct: decoupled representation as defined doesn't capture belief-like representation, and, properly understood, decoupled representation turns out to be ubiquitous among multicellular animals. However, some of the key ideas are right, or along the right lines, and suggestions are made for modifying and expanding the conceptual framework. (shrink)

Khutoretskii's Theorem states that the Rogers semilattice of any family of c.e. sets has either at most one or infinitely many elements. A lemma in the inductive step of the proof shows that no Rogers semilattice can be partitioned into a principal ideal and a principal filter. We show that such a partitioning is possible for some family of d.c.e. sets. In fact, we construct a family of c.e. sets which, when viewed as a family of d.c.e. sets, has (up (...) to equivalence) exactly two computable Friedberg numberings ¼ and ν, and ¼ reduces to any computable numbering not equivalent to ν. The question of whether the full statement of Khutoretskii's Theorem fails for families of d.c.e. sets remains open. (shrink)

We prove that a enumerable degree is contiguous iff it is locally distributive. This settles a twenty-year old question going back to Ladner and Sasso. We also prove that strong contiguity and contiguity coincide, settling a question of the first author, and prove that no $m$-topped degree is contiguous, settling a question of the first author and Carl Jockusch [11]. Finally, we prove some results concerning local distributivity and relativized weak truth table reducibility.

Answering a question of Per Lindström, we show that there is no “plus-capping” degree, i.e. that for any incomplete r.e. degreew, there is an incomplete r.e. degreea>w such that there is no r.e. degreev>w witha∩v=w.

This article discusses symmetry as an analytical tool for sociological analysis. Symmetry is presented as a property of social formations and a way to generate information about them through their mutual comparisons. The concept thus displaces the old dichotomy between individual and society. The latter forces to think in terms of wholes and parts, unduly limiting the possibilities at hand by keeping individuals as prisoners of societies, as it were. Symmetry opens the door for more alternatives by making room for (...) more social formations at the same time. To develop this concept, the article turns to both Niklas Luhmann’s systems theory and Harrison White’s network theory which are presented as enacting an “order from noise” approach (as opposed to an “order from order” approach). The article then reconstructs a whole spectrum going from social formations at a high level of symmetry to social formations at a low level of symmetry. At the first end, we have social formations like groups that define the identities of persons (or even define persons as identities). At the other end, we have entire functional sectors (like politics, science, law, economy, etc.) whose chief characteristic is to be asymmetric to each other (so that doing politics, for instance, is unlike doing science and vice-versa).

Carl Vogt’s quarrel with Rudolph Wagner is considered to be a culmination of the materialism dispute in the 19th century. Out of this basically academic issue on the nature of human mental functions, a personal dispute quickly developed which was unrivalled in thematic incisiveness and expression. The aim of this study is the detailed linguistic analysis of the polemics and argumentation in this dispute based on extensive text excerpts, in which for the first time detailed linguistic studies on Vogt and (...) Wagner are presented. (shrink)

Diese unter der Leitung der Proff. Dres. Theophanopúlu-Kontú, Magulás und Charalampákés angefertigte, fleißige und umsichtige Diss. einer Gymnasiallehrerin, die sich dafür vier Jahre unbezahlten Urlaub genommen hatte, ist – nach zwei alten Arbeiten Maidhofs (1920 und 1931) – die erste systematische Behandlung der Rückwanderer im neugriechischen Wortschatz (im Folg.: RW). Die Verfasserin (Verf.) hat sich bestens in die internationale Literatur zu den aus einer Sprache A stammenden, in eine oder mehrere andere Sprachen (B, evtl. C usw.) entlehnten und schließlich in (...) ein jüngeres Stadium von A zurückentlehnten Wörter eingearbeitet: Ihre Literaturliste (S. 265–273) umfasst nicht weniger als 146 griech., engl., französ., italien., deutsche und türk. Titel. Das Thema ist für das Gesamtgriechische von besonderem Interesse, da während seiner so besonders langen und gut dokumentierten Existenz naturgemäß eine erkleckliche Zahl von Lexemen zurückgewandert sind, offensichtlich mehr als in jede andere Sprache Europas. So hat denn die Verf. nach eigener Angabe 170, realiter ca. 200 solche RW zusammengestellt und deren Geschichte meist ausführlich und überzeugend dokumentiert und damit ein Kapitel neugriechischer Etymologie geschrieben. Sinnvollerweise hat sie dabei auf eine Behandlung der immer uferloser werdenden gräkogenen Internationalismen in Technik und Wissenschaften verzichtet und sich auf das Alltagsvokabular beschränkt. Dass jedoch auch eine erste derartige Sammlung nicht annähernd vollständig sein wird, liegt auf der Hand; so ergänzt der Rezensent (im Folg.: R.) ohne langes Suchen folgende Fälle neuzeitlicher RW (nach Sprachen, aus denen sie zurückgekommen sind; vermittelnde Sprachen, etwa Latein, werden hierbei gewöhnlich weggelassen).

This paper defines reduction on derivations (cut-elimination) in the Strict Intersection Type Assignment System of an earlier paper and shows a strong normalization result for this reduction. Using this result, new proofs are given for the approximation theorem and the characterization of normalizability of terms using intersection types.

We establish that the isomorphism problem for the classes of computable nilpotent rings, distributive lattices, nilpotent groups, and nilpotent semigroups is \-complete, which is as complicated as possible. The method we use is based on uniform effective interpretations of computable binary relations into computable structures from the corresponding algebraic classes.

This paper examines the way in which Ordinary Language Philosophy came to exert an important influence on the work done at Aarhus University’s department of philosophy in the latter half of the 20th century. The first section depicts the rise of Ordinary Language Philosophy as an international movement centered around Oxford in the wake of World War ii. The second section goes on to describe how it was brought to Aarhus by Professor Justus Hartnack, who had been deeply influenced by (...) the movement during stays abroad in the UK and the US. The following three sections move on to describe some of the important ways in which Ordinary Language Philosophy has influenced the work of three of Hartnack’s most prominent students, who have influenced the life of the department in crucial ways from the 1970s until recently. Finally, the paper ends by briefly assessing the legacy and contemporary influence of Ordinary Language Philosophy in Aarhus. (shrink)

This anthology of 78 readings includes historically diverse writings by men and women working within Asian, African, Latin American, and native North American cultural traditions, as well as classic and contemporary readings from Western sources. The aim is to present students with a more global, multicultural, and gender-conscious picture of philosophical inquiry and the range of issues it confronts.

This article discusses the identity formation process former right wing extremists go through, during and especially after being involved in an exit program for those leaving right wing extremist environments. Based on an ethnographic investigation (and practice theoretical approach), the article argues that participation in culturally defined worlds – such as the extremist right – develops sensitivities and sensibilities that endure. This enables them to engage in social actions, gain a position and develop a correlated identity, but it is also (...) the reason why it can be very demanding for the individual to leave an extremist environment. Perceived from the position of former right wing extremists, the article considers the challenges involved in (re)integrating into society by those stigmatized by a criminal and extremist past. It explores how individuals leaving a right wing extremist group handle themselves in a new world when their embodied knowledge and habitual responding are no longer appropriate, and investigates the many aspects individuals struggle with years after their engagement, when they do not know who to become and how to act.

Conciliationism holds that disagreement of apparent epistemic peers often substantially undermines rational confidence in our opinions. Uniqueness principles say that there is at most one maximally rational doxastic response to any given batch of total evidence. The two views are often thought to be tightly connected. This paper distinguishes two ways of motivating conciliationism, and two ways that conciliationism may be undermined by permissive accounts of rationality. It shows how conciliationism can flourish under certain strongly permissive accounts of rationality. This (...) occurs when the motivation for conciliationism does not come from taking disagreement as evidence of one's own rational failings. However, divorcing the motive for conciliating from worries about rationality does not remove a feature of conciliationism that some find troubling: that conciliationism can lead to cases of “rational toxicity,” in which the most rational response to one's evidence involves violating some rational ideal.

We often get evidence concerning the reliability of our own thinking about some particular matter. This “higher-order evidence” can come from the disagreement of others, or from information about our being subject to the effects of drugs, fatigue, emotional ties, implicit biases, etc. This paper examines some pros and cons of two fairly general models for accommodating higher-order evidence. The one that currently seems most promising also turns out to have the consequence that epistemic akrasia should occur more frequently than (...) is sometimes supposed. But it also helps us see why this might not be a bad thing. (shrink)

Oregon is the only state in the United States where a physician may legally prescribe a lethal dose of barbiturate for a patient intending suicide. The Oregon Death with Dignity Act was passed by voters in 1994 and came into effect after much legal wrangling in October of 1997. At the same time, a cabinetmaker named Pat Matheny was struggling with progressive weakness from amyotrophic lateral sclerosis, or ALS. I met with Pat and his family for a lengthy interview in (...) October 1998 in Coos Bay, Oregon, for a television news report on his decision to get a lethal prescription. Below is an extract from that interview. On the day this introduction was written, 10 March 1999, Pat took the prescribed lethal overdose of barbiturates and died at home. His illness was taking his voice, he could not move his hands or legs, and breathing was becoming very difficult. His mother told me he knew that was for him. (shrink)
