This article is a reply to Jeanne Peijnenburg's argument for retrocausality in "Shaping Your Own Life." Although it is perfectly possible to make sense of the way Peijnenburg deals with the subject of changing the past, there is no need to think this implies retrocausality.

Making adaptive choices between solution strategies is a central element of contemporary mathematics education. However, previous studies signal that students make suboptimal choices between mental and written strategies to solve division problems. In particular, some students of a lower math ability level appear inclined to use mental strategies that lead to lower performance. The current study uses a pretest-training-posttest design to investigate the extent to which these students’ choices for written strategies and performance may be increased. Sixth graders of below-average (...) mathematics level (N = 147) participated in one of two training conditions: an explicit-scaffolding training designed to promote writing down calculations or a practice-only training where strategy use was not explicitly targeted. Written strategy choices and performance increased considerably from pretest to posttest for students in both training conditions, but not in different amounts. Exploratory results suggest that students’ strategy choices may also be affected by their attitudes and beliefs and the sociocultural context regarding strategy use. (shrink)

Superfluous People describes Hannah Arendt's political and philosophical views on Nazi totalitarianism and the Shoah. In her contemplation of evil, Arendt initially spoke of the Shoah as a "radical evil," a term used by Kant. However, unlike Kant, Arendt's radical evil cannot be explained by human motives. Many years later she changed her mind and spoke of "the banality of evil," characterized by an inability to think and judge. Superfluous People seriously considers the question of whether thinking and judging can (...) prevent evil. (shrink)

At conceptual and linguistic levels of cognition, events are said to be represented in terms of abstract categories, for example, the sentence Jackie cut the bagel with a knife encodes the categories Agent (i.e., Jackie) and Patient (i.e., the bagel). In this paper, we ask whether entities such as the knife are also represented in terms of such a category (often labeled “Instrument”) and, if so, whether this category has a prototype structure. We hypothesized the Proto-instrument is a tool: a (...) physical object manipulated by an intentional agent to affect a change in another individual or object. To test this, we asked speakers of English, Dutch, and German to complete an event description task and a sentence acceptability judgment task in which events were viewed with more or less prototypical instruments. We found broad similarities in how English, Dutch, and German partition the semantic space of instrumental events, suggesting there is a shared concept of the Instrument category. However, there was no evidence to support the specific hypothesis that tools are the core of the Instrument category—instead, our results suggest the most prototypical Instrument is the direct extension of an intentional agent. This paper supports theoretical frameworks where thematic roles are analyzed in terms of prototypes and suggests new avenues of research on how instrumental category structure differs across linguistic and conceptual domains.

The sole diagram in On the Origin of Species is generally considered to be merely an illustration of Darwin’s ideas, but such an interpretation ignores the fact that Darwin himself expressly stated that the diagram helped him to discover and express his ideas. This article demonstrates that developing the so-called “tree diagram” substantially aided Darwin’s heuristics. This demonstration is based on an interpretation of the diagram and of 17 sketches found in Darwin’s scientific papers. The key to this interpretation is (...) the meaning that Darwin assigned to the graphic elements he used to construct the preliminary sketches and the diagram. I argue that each of the sketches contributed to the shaping of Darwin’s ideas and that, in their succession, each added new elements that ultimately resulted in the fully developed published diagram.

This paper examines the main orthographic innovations of the early Islamic orthography in comparison to the Nabataean orthography and traces through new epigraphic evidence when and where these innovations came to be used. It is shown that a number of them clearly develop already in the pre-Islamic period. Besides this, the paper looks at the complexities of Arabic orthography and morphophonological spelling as it is reflected in the Quranic orthography as well as pre-Islamic inscriptions and argues that the early Islamic (...) orthography represents the continuation of a developed Hijazi scribal tradition.

Research has by and large shown the negative effects of state orientation, that brooding over past events (i.e., state orientation) leads to more negative emotions and less well-being than quickly getting over past events (i.e., action orientation). However, this past research has primarily focused on how people cope with negative events and bad outcomes. The present research focuses on how people cope with positive events with good outcomes. Study 1 found that state-oriented people felt better after a windfall than action-oriented (...) people. Study 2 found that state-oriented people felt not only worse when things turned out bad but also better when things turned out well than action-oriented people. Study 3 replicated the positive effect of state orientation on positive emotions with an experimental induction of action vs. state orientation. These results show that in positive situations state orientation can have emotional benefits – in other words, they show the bright side of brooding. (shrink)

Awjila Berber is a highly endangered Berber variety spoken in eastern Libya. The minimal material available on it reveals that the language is in some respects very archaic and in others grammatically unique, and as such is of particular comparative and historical interest. Fieldwork has been impossible for decades due to the political situation. Recently, however, several inhabitants of Awjila have set up a Facebook group Ašal=ənnax (“our village”), posting largely in Awjili. Analysis of this partly conversational corpus makes it (...) possible to extend our knowledge of the language, yielding unattested words and constructions. Examination of its grammatical features also reveals that these posters’ usage is heavily influenced by Arabic, showing language attrition absent from earlier data; even subject-verb agreement has been extensively reworked. In both respects, this study casts light upon the uses and limits of social media as a source of linguistic material. (shrink)

A future without habit: Lewis Mumford This article discusses the relevance of historian of technology Lewis Mumford (1895-1990) for a philosophy of habit. Although Mumford is not traditionally interpreted as a philosopher of habit, the aim of the article is to show that Mumford’s approach to biotechnics contains (i) an anthropology in which habit, rather than technology, is of decisive importance in human history; (ii) an original interpretation of habit which differs from both the classical Aristotelian approach, as well as (...) from a modernist approach like that of Hegel; (iii) a non-materialist interpretation of work, which problematizes the recent emergence of flexible work as a problem of habit, allowing for an original evaluation of the problem of precarization. What is at stake here is a re-evaluation of the relation between habit and psychopathology, in light of which Mumford shows that modern work tends to destabilize millennia-old habits, prompting the question of how these habits might be sustained.

The two great modern naturalists, Linnaeus and Darwin, expressed their intuition about how best to visualize patterns of affinities, that is, morphological similarities and divergences between taxa. Linnaeus suggested that “all plants show affinities on all sides, like a territory on a geographical map,” while Darwin thought that it was virtually impossible to understand the affinities between living and extinct species without a genealogical tree. Genealogical trees follow the diachronic, evolving logic of a timeline, whereas maps depict a synchronous pattern (...) of extant taxa. Although the two seem unrelated, various naturalists made attempts to combine them. Surprisingly, these resulted in three-dimensional images that, in order to be observed, had to be projected on paper. The naturalists Max Fürbringer and Richard Bowdler Sharpe were aware of this fact, but even Darwin himself twice combined the basic intuitions underlying the two modes of representation to produce three-dimensional images. This article is a brief history of the efforts to merge genealogical trees and map-like cross sections of affinities into one three-dimensional image. (shrink)

A self-fulfilling prophecy in neuroprognostication occurs when a patient in coma is predicted to have a poor outcome, and life-sustaining treatment is withdrawn on the basis of that prediction, thus directly bringing about a poor outcome for that patient. In contrast to the predominant emphasis in the bioethics literature, we look beyond the moral issues raised by the possibility that an erroneous prediction might lead to the death of a patient who otherwise would have lived. Instead, we focus on the (...) problematic epistemic consequences of neuroprognostic SFPs in settings where research and practice intersect. When this sort of SFP occurs, the problem is that physicians and researchers are never in a position to notice whether their original prognosis was correct or incorrect, since the patient dies anyway. Thus, SFPs keep us from discerning false positives from true positives, inhibiting proper assessment of novel prognostic tests. This epistemic problem of SFPs thus impedes learning, but ethical obligations of patient care make it difficult to avoid SFPs. We then show how the impediment to catching false positive indicators of poor outcome distorts research on novel techniques for neuroprognostication, allowing biases to persist in prognostic tests. We finally highlight a particular risk that a precautionary bias towards early withdrawal of life-sustaining treatment may be amplified. We conclude with guidelines about how researchers can mitigate the epistemic problems of SFPs, to achieve more responsible innovation of neuroprognostication for patients in coma. (shrink)

To what extent does perceptual language reflect universals of experience and cognition, and to what extent is it shaped by particular cultural preoccupations? This paper investigates the universality~relativity of perceptual language by examining the use of basic perception terms in spontaneous conversation across 13 diverse languages and cultures. We analyze the frequency of perception words to test two universalist hypotheses: that sight is always a dominant sense, and that the relative ranking of the senses will be the same across different (...) cultures. We find that references to sight outstrip references to the other senses, suggesting a pan-human preoccupation with visual phenomena. However, the relative frequency of the other senses was found to vary cross-linguistically. Cultural relativity was conspicuous as exemplified by the high ranking of smell in Semai, an Aslian language. Together these results suggest a place for both universal constraints and cultural shaping of the language of perception. (shrink)

Our lives are increasingly intertwined with the digital realm, and with new technology, new ethical problems emerge. The academic field that addresses these problems—which we tentatively call ‘digital ethics’—can be an important intellectual resource for policy making and regulation. This is why it is important to understand how the new ethical challenges of a digital society are being met by academic research. We have undertaken a scientometric analysis to arrive at a better understanding of the nature, scope and dynamics of (...) the field of digital ethics. Our approach in this paper shows how the field of digital ethics is distributed over various academic disciplines. By first having experts select a collection of keywords central to digital ethics, we have generated a dataset of articles discussing these issues. This approach allows us to generate a scientometric visualisation of the field of digital ethics, without being constrained by any preconceived definitions of academic disciplines. We have first of all found that the number of publications pertaining to digital ethics is exponentially increasing. We furthermore established that whereas one may expect digital ethics to be a species of ethics, we in fact found that the various questions pertaining to digital ethics are predominantly being discussed in computer science, law and biomedical science. It is in these fields, more than in the independent field of ethics, that ethical discourse is being developed around concrete and often technical issues. Moreover, it appears that some important ethical values are very prominent in one field (e.g., autonomy in medical science), while being almost absent in others. We conclude that to get a thorough understanding of, and grip on, all the hard ethical questions of a digital society, ethicists, policy makers and legal scholars will need to familiarize themselves with the concrete and practical work that is being done across a range of different scientific fields to deal with these questions.

Conversational artificial agents and artificially intelligent voice assistants are becoming increasingly popular. Digital virtual assistants such as Siri, or conversational devices such as Amazon Echo or Google Home are permeating everyday life, and are designed to be more and more humanlike in their speech. This study investigates the effect this can have on one’s conformity with an AI assistant. In the 1950s, Solomon Asch’s already demonstrated the power and danger of conformity amongst people. In these classical experiments test persons were (...) asked to answer relatively simple questions, whilst others pretending to be participants tried to convince the test person to give wrong answers. These studies were later replicated with embodied robots, but these physical robots are still rare. In light of our increasing reliance on AI assistants, this study investigates to what extent an individual will conform to a disembodied virtual assistant. We also investigate if there is a difference between a group that interacts with an assistant that communicates through text, one that has a robotic voice and one that has a humanlike voice. The assistant attempts to subtly influence participants’ final responses in a general knowledge quiz, and we measure how often participants change their answer after having been given advice. Results show that participants conformed significantly more often to the assistant with a human voice than the one that communicated through text. (shrink)

Background: The classical symptom specificity hypothesis (Blatt, 1974) links obsessional symptoms to autonomous interpersonal behavior. Inconsistent findings from cross-sectional group studies on symptom specificity have previously been associated with several conceptual and methodological limitations intrinsic to nomothetic research. Previous empirical case research reported ambivalences between autonomous and dependent interpersonal behavior in obsessional pathology. Aim and Method: The present ‘theory-building’ case study specifically aims at further refinement of the classical symptom specificity hypothesis by testing specific operationalizations within an empirical single case (...) design. Consensual Qualitative Research for Case studies is used to quantitatively and qualitatively describe the longitudinal, clinical interplay between obsessional symptoms and interpersonal dynamics throughout the process of a psychodynamic therapy. Interpersonal functioning is assessed by means of the Core Conflictual Relationship Theme method. The classical symptom specificity hypothesis is contrasted to an alternative hypothesis of interpersonal ambivalences as determinants of obsessional symptoms. Results: Close associations between obsessions and interpersonal dynamics are observed. Findings predominantly affirm the ambivalence hypothesis rather than the classical symptom specificity hypothesis. Psychodynamic interventions focusing on interpersonal conflicts are related to symptomatic changes. Conceptual and methodological considerations, limitations and future research indications are discussed. (shrink)

To reduce CO2 emissions requires greater reliance on renewable sources of energy for generating electricity, especially adoption of large-scale wind generation. This study investigates possible approaches and/or policies that increase efficient use of renewable energy and reduce greenhouse gas emissions in a cost effective manner. We develop a constrained optimization model of two electricity systems to identify the impact of increasing wind generating capacity and examine how carbon prices (taxes, allowances) impact the penetration of wind power into the electricity grids. (...) Rather than employ engineering cost functions, marginal cost functions are estimated using hourly offer data from the Alberta Electric System Operator. We determine optimal removal of coal generating facilities as greater levels of wind capacity are installed in an integrated Alberta-BC electricity system; and examine the economic costs and institutional incentives that affect the ability to store intermittent wind-generated power in BC’s hydro reservoirs during low demand. The marginal shadow price of storage is zero, whichindicates that there is more than enough water behind the dams given Alberta’s relatively small demand for storage and limited intertie transmission capacity.

This paper provides an empirical case study of the relationship between corporate social responsibility (CSR) and the new competition regulation in the Netherlands. The leading question in this case study is whether the new institutional arrangement has allowed for the possibility that reasonable exceptions can be made to the principle that inter-firm cooperation is prohibited. That is to say: does the new institutional arrangement allow for the possibility of 'well organized but not 'perfect' markets'? The investigation focuses on the Netherlands, (...) which constitutes an exemplary case as the Dutch are committed to both strengthen the competitiveness of the market and allow for exceptions on behalf of non-economic values such as CSR. The authors expect that the Dutch context will prevent a doctrinal and categorical rejecting of any good argument to make an exception to the rule that inter-firm cooperation must be prohibited.
