The core theme of the special issue in which this article appears is the inherent impossibility of confining the knowledge required to build and sustain the instruments of travel to a single space or institution. This is certainly true for the ships that built empires – the large sailing and later steam ships produced by navies and companies in the process of European expansion. Ships traveled between polities and required repairs overseas, taking the construction knowledge and practices with them. Skilled (...) laborers – experienced shipwrights and increasingly also trained engineers – helped to transfer shipbuilding practices across oceans, and to adapt these practices to local conditions based on forms of “blended know-how.” This article explores how the circulation of shipbuilding knowledge and practices within and between maritime empires changed with the increasing pace of industrialization. It does so on the basis of three moments: the Dutch East India Company’s shipbuilding activities in Asia in the seventeenth and eighteenth centuries; the interaction between private industry and the Dutch state in advancing machine-manufacturing in both the Netherlands and on Java in the 1830s and 1840s; and the aid provided by Dutch engineers in laying the groundwork for Japanese industrial warship-construction in the second half of the nineteenth century. Such transfers put high demands on the capacities of states and naval administrators in controlling the flows of necessary resources and skilled labor, requiring complex arrangements between states and private capital. Industrialization did not change this basic fact, but it did change the nature of these arrangements. Although shipbuilding knowledge always remained practice-driven, highly mobile and susceptible to local adaptation, the increasing technological demands created by the transition from sail to steam and wood to iron, combined with the extension of the power of states and transnationally operating manufacturing companies, considerably changed the institutional embeddings and societal consequences of its circulation.

Two key research issues in the field of causal learning are how people acquire causal knowledge when observing data that are presented sequentially, and the level of abstraction at which learning takes place. Does sequential causal learning solely involve the acquisition of specific cause-effect links, or do learners also acquire knowledge about abstract causal constraints? Recent empirical studies have revealed that experience with one set of causal cues can dramatically alter subsequent learning and performance with entirely different cues, suggesting that (...) learning involves abstract transfer, and such transfer effects involve sequential presentation of distinct sets of causal cues. It has been demonstrated that pre-training can modulate classic causal learning phenomena such as forward and backward blocking. To account for these effects, we propose a Bayesian theory of sequential causal learning. The theory assumes that humans are able to consider and use several alternative causal generative models, each instantiating a different causal integration rule. Model selection is used to decide which integration rule to use in a given learning environment in order to infer causal knowledge from sequential data. Detailed computer simulations demonstrate that humans rely on the abstract characteristics of outcome variables to select a causal integration rule, which in turn alters causal learning in a variety of blocking and overshadowing paradigms. When the nature of the outcome variable is ambiguous, humans select the model that yields the best fit with the recent environment, and then apply it to subsequent learning tasks. Based on sequential patterns of cue-outcome co-occurrence, the theory can account for a range of phenomena in sequential causal learning, including various blocking effects, primacy effects in some experimental conditions, and apparently abstract transfer of causal knowledge.

Using the matching bias example, the aim of the present studies was to show that adults' reasoning biases are due to faulty executive inhibition programming. In the first study, the subjects were trained on Wason's classical card selection task; half were given training in how to inhibit the perceptual matching bias (experimental group) and half in logic without the inhibition component (control group). On the pre- and post-tests, their performance was assessed on the Evans conditional rule falsification task (...) (with a negation in the antecedent of the rule), a task that also involves matching bias. In addition, subjects were tested for perceptual field dependence/independence using the Embedded Figures Test. The results brought out a specific inhibition training effect, as well as a clear-cut relationship in the experimental group between receptiveness to training and perceptual field independence. In the second study, the training paradigm was the same except that on the pre- and post-tests, the negation was in the consequent of the conditional rule (in this case, the perceptual matching response corresponds to the logical response). The subjects succeeded on the pre-test, and the matching-bias inhibition training had a negative effect on post-test performance. This specific negative priming effect confirms the inhibitory impact of our experimental training and outlines the dissociation of inhibition and logical components. (shrink)

Conventional methods for fault diagnosis typically require a substantial amount of training data. However, for equipment with high reliability, it is arduous to form a large-scale well-annotated dataset due to the expense of data acquisition and costly annotation. Besides, the generated data have a large number of redundant features which degraded the performance of models. To overcome this, we proposed a feature transfer scenario that transfers knowledge from similar fields to enhance the accuracy of fault diagnosis with (...) small sample. To reduces the redundant information, data were filtered according to manifold consistency. Then, features were extracted based on CNN and feature transfer was conducted. For adequate fitness, the joint adaptation of conditional distribution and marginal distribution was used between the two domains. Minimum structural risk and MMD of adaptation were two indicators weighted for training the model. To test the efficiency of the model, we built an airborne fuel pump testbed, and contributed a new dataset that contained 15 categories of fault data, which serves as the small sample dataset in this research. Then the proposed model was applied in our experimental data. As a result, the fault diagnosis rate increases by 28.6% through our proposed model, which is more precise than other classical methods. The results of feature visualization further demonstrate that the features are more distinguished through the proposed method. All code and data are accessible on my GitHub. (shrink)

There exist valuable methods for theorem proving in non classical logics based on translation from these logics into first-order classical logic (abbreviated henceforth FOL). The key notion in these approaches istranslation from aSource Logic (henceforth abbreviated SL) to aTarget Logic (henceforth abbreviated TL). These methods are concerned with the problem offinding a proof in TL by translating a formula in SL, but they do not address the very important problem ofpresenting proofs in SL via a backward (...) translation. We propose a framework for presenting proofs in SL based on a partial backward translation of proofs obtained in a familiar TL: Order-Sorted Predicate Logic. The proposed backward translation transfers some formulasF TL belonging to the proof in TL into formulasF SL , such that the formulasF SL either (a) belong to a corresponding deduction in SL (in the best case) or, (b) are semantically related in some precise way, to formulas in the corresponding deduction in SL (in the worst case). The formulasF TL andF SL can obviously be considered aslemmas of their respective proofs. Therefore the transfer of lemmas of TL gives at least a skeleton of the corresponding proof in SL. Since the formulas of a proof keep trace of the strategy used to obtain the proof, clearly the framework can also help in solving another fundamental and difficult problem:the transfer of strategies from classical to non classical logics. We show how to apply the proposed framework, at least to S5, S4(p), K, T, K4. Two conjectures are stated and we propose sufficient (and in general satisfactory) conditions in order to obtain formulas in the proof in SL. Two particular cases of the conjectures are proved to be theorems. Three examples are treated in full detail. The main lines of future research are given. (shrink)

The distinction between redistribution and predistribution is now embraced by many political philosophers, like Jacob Hacker or Martin O’Neill. This distinction, we could think, is particularly important for the question of how we react to crises, like the current coronavirus pandemic. If the policies take the form of taxes and transfers, like cash-flow assistance, it is redistribution, one could argue. If the policies are meant to alter pretax incomes, as policies changing the conditions for bankruptcy are, it is predistribution. This (...) paper shows why that is not so. Re- and predistribution are only techniques of presentation. They are meant to put the emphasis on different ways we can depict the consequences of policies. Both the “pre-” of predistribution and the “re-” of redistribution are misnomers. This paper argues that we cannot establish a strong distinction between policies that are re- and those that are predistributive, as the case of the basic income will show. Given that classical liberals endorsed egalitarian policies, moreover, the idea of predistribution cannot be used by progressives who want to differentiate their social justice platforms from the classical liberal program.

The issue whether psychopathic offenders are practically rational has attracted philosophical attention. The problem is relevant in theoretical discussions on moral psychology and in those concerning the appropriate social response to the crimes of these individuals. We argue that classical and current experiments concerning the instrumental learning in psychopaths cannot directly support the conclusion that they have impaired instrumental rationality, construed as the ability for transferring the motivation by means-ends reasoning. In fact, we defend the different claim (...) that these experiments appear to show that psychopaths in certain circumstances are not aware of the relevant means for their ends. Moreover, we suggest how further empirical research could help to settle the issue. (shrink)

Starting from the current trend to digitise the university, this thesis aims to clarify the specific relation between university thinking and its use of media. This thesis is an investigation concerning the sensorial and medial conditions which enable the event of thinking to emerge at the university, i.e. conditions which do not make thinking necessary, but possible. Thinking is approached as an event which can happen while studying at the university, not as an outcome, nor a disposition or skill. (...) The ambition of this thesis is theory development and of making a contribution in the field of philosophy of education. The theoretical framework discussed in chapters one and two will allow first, an analysis of the university sensorium inspired by the work of Ivan Illich who, through a history of the senses, pioneered this kind of research applied to medieval reading practices. Secondly, the work of media philosopher Vilém Flusser is used to operationalize the analysis of media at the university; this thesis will use the Flusserian concepts of code, modes of consciousness, transcoding, gestures, intellectual field, dialogue and apparatus. The methodology consists of a novel approach inspired by Flusser’s phenomenology of gestures: in order to find traces of thinking, this investigation looks for gestures (with media) occurring in university practices, gestures which seem to imply some form of coding or transcoding. The first chapter critically discusses Ivan Illich’s historical hypothesis of the mediatic specificity of the university thinking. Illich works with a particular conception of the history of the senses through which he shows how the invention of the optical text and its way of reading gave rise to a new way of thinking which was later fostered by the university. The text emerges as an instrumental way of using the book for studying and thinking, a profanation and suspension of the book. This move is taken to be the signature move of the university which enables a particular way of thinking: abstract and non-visual thinking, which is made present through the event of reading. The second chapter introduces the media-theoretical framework of Flusser by discussing his particular take on codes and the modes of consciousness enabled by the dominant codes. Provisionally, transcoding is taken to be an indication of the event of thinking. The threshold introduces the approach of a phenomenology of gestures which will be used in the following two chapters. The third chapter examines the practice of university lecturing from a sensorial and gestural perspective by using several direct observations of lectures and historical reports of lectures. It was found that the lecture does not promote any particular sense, hence no particular mode of consciousness, and that the media in the lecture suffers a continuous transcoding. Thinking in the lecture was described as a thinking which suddenly makes itself present for all those attending the lecture. The fourth chapter examines MOOCs which are taken to be the digital counterpart of the university course. The specific media usage enabled by MOOCs is described starting from two case studies: an xMOOC and the bMOOC (designed by KU Leuven and LUCA researchers). Using interviews and an autoethnographic account, this chapter finds indications of what could be digital gestures in the MOOC and concludes that thinking in the MOOC occurs as a collective construction of a techno-image. The fifth and final chapter outlines the theoretical contributions of this thesis. The kind of thinking made possible by university practices is described as a form of collective thinking, non-productive and anti-apparatus. The ways in which this thinking is made possible are theorised by introducing the notion of mediatic displacement, a specific event in which the particular logic of media is suspended in such a way as to make room for a thinking which is not determined by any mediality. The notion of intellectual askesis is proposed for the collective enactment of attention, as the sensorial condition which makes possible the mediatic displacement. In light of these findings, the thesis proposes to understand the promise of the digital university as still a utopian project to come, because it cannot yet enable the sensorial and collective attention techniques which the classical university managed to enact through its study practices.

This essay will survey various considerations that arise when a branch of physics requires formulation in terms of partial differential equations (or some facsimile thereof). My examples will derive almost exclusively from classical continuum (=smeared out matter) mechanics. Although the relevant formal facts are well known, it is difficult to find coherent discussions of how the underlying phenomena ought to be viewed. In this paper, I will give an introduction to some of the issues, although I will (...) confess at the outset that I am not certain how these matters should be finally adjudicated. Certainly it would be helpful if philosophy paid more attention to the underlying issues.Some of the points I will discuss bear upon some of Professor Sklar’s observations. Although my attention will be largely directed towards the status of boundary conditions (and related forms of singular surface), many of my examples can be adapted, mutatis mutandis, to initial conditions as well.

According to the brain drain argument, there are good reasons for states to limit the exit of their skilled workers (more specifically, healthcare workers), because of the negative impacts this type of migration has for other members of the community from which they migrate. Some theorists criticise this argument as illiberal, while others support it and ground a duty to stay of the skilled workers on rather vague concepts like patriotic virtue, or the legitimate expectations of their state and (...) co-citizens. In this article, on the contrary, we suggest that the liberal conception of states’ legitimate political authority demands, and not just permits, that developing states from which migration of skilled workers occurs set up contractual mechanisms. These mechanisms will ensure that state-funded training in the health sector is provided against a commitment on the part of future professionals to reciprocate with their services for the benefits obtained. If one of the conditions for the state to maintain legitimate political authority is to provide basic services such as healthcare to its subjects (while respecting at the same time their autonomy and freedom), then this is what developing states affected by the brain drain ought to do. What we call the authority-based approach to the brain drain also helps to clarify the obligations that other states have not to interfere with these contractual mechanisms when they exist, and not to profit from their absence. Inspired by FIFA’s legal instruments of training compensation and solidarity mechanism for the transfer of players, we conclude by suggesting a plausible global policy to complement this authority-based approach.
