“Je doute qu'il y ait un dialogue de la chenille et du papillon”A. MatrauxThe most ordinary events astonish only those who think about them. What can be more natural than two people talking? They are from the same country, they speak the same language, they understand one another. They have things to say to each other and they say them. Anyone who would try to question such evident truisms would be seen as attempting to be a spinner of paradoxes. And (...) yet…First of all is it as natural as it appears that two people should stop and speak? To an impartial observer of the behavior of one's peers this would not seem to be the case. Most of the people we rub elbows with daily—in the street, in the subway, on a beach, in a hotel or even in the apartment building where we have lived for ten years—are people whom we do not accost and to whom we never speak. In order for people to speak to one another, certain circumstances must exist; there must be a ritual of introduction and a mutual consent that often occurs only after a certain resistance has been overcome. There are important differences to be observed in this respect among different peoples and, within the same nation, among people of different classes. But in every case dialogue is preceded by a preparatory phase of prudent observation, reserve and mistrust during which the partners size one another up and seek to situate themselves in relation to each other.

Constructive empiricism is supposed to offer a positive alternative to scientific realism that dispenses with the need for metaphysics. I first review the terms of the debate before arguing that the standard objections to constructive empiricism are not decisive. I then explain van Fraassen's views on modality and counterfactuals, and argue that, because constructive empiricism recommends on epistemological grounds belief in the empirical adequacy rather than the truth of theories, it requires that there be an objective modal distinction between the (...) observable and the unobservable. This conclusion is incompatible with van Fraassen's empiricism. Finally I explain some further problems for constructive empiricism that arise when we consider modal matters. (shrink)

It has been suggested in the literature that spatial coherence of the wave function can be dynamically suppressed by fluctuations in the spacetime geometry. These fluctuations represent the minimal uncertainty that is present when one probes spacetime geometry with a quantum probe. Two similar models have been proposed, one by Diósi and one by Karolyhazy and collaborators, based on apparently unrelated minimal spacetime bounds. The two models arrive at somewhat different expressions for the dependence of the localization coherence length on (...) the mass and size of the quantum object. In the present article we compare and contrast the two models from three aspects: comparison of the spacetime bounds, method of calculating decoherence time, comparison of noise correlation. We show that under certain conditions the minimal spacetime bounds in the two models can be derived one from the other. We argue that the methods of calculating the decoherence time are equivalent. We re-derive the two-point correlation for the fluctuation potential in the K-model, and confirm the earlier result of Diósi and Lukács that it is non-white noise, unlike in the D-model, where the corresponding correlation is white noise in time. This seems to be the origin of the different results in the two models. We derive the non-Markovian master equation for the K-model. We argue that the minimal spacetime bound cannot predict the noise correlation uniquely, and additional criteria are necessary to accurately determine the effects of gravitationally induced decoherence.

This article uses diary data from the most recent Australian Bureau of Statistics Time Use Survey to compare by gender total child care time calculated in the measurements of main activity, main or secondary activity, and total time spent in the company of children. It also offers an innovative gender comparison of relative time spent in the activities that constitute child care, child care as double activity, and time with children in sole charge. These measures give a fuller picture of (...) total time commitment to children and how men and women spend that time than has been available in previous time use analyses. The results indicate that compared to fathering, mothering involves not only more overall time commitment but more multitasking, more physical labor, a more rigid timetable, more time alone with children, and more overall responsibility for managing care. These gender differences in the quantity and nature of care apply even when women work full-time. (shrink)

Speakers often answer a question with what appears to be merely a phrase, a fragment of a sentence, rather than with a full sentence. Merchant (2004) offers an analysis of fragment answers in which the new information/answer is fronted to a clause-peripheral position and the remainder of the sentence is not pronounced. Two written acceptability judgment experiments are reported that tested predictions of this analysis. The first, in English, tested the prediction that clausal fragment answers should only be fully acceptable (...) when the clausal answer is introduced by an overt complementizer (What did May deny? That Josh left.). This is because clauses may front only when an overt complementizer is present (That Josh left, May denied, but not *Josh left, May denied). The second study was conducted in German, a language that does not permit prepositions to be stranded, left behind, when a noun phrase is moved in overt syntactic structures such as questions or topicalizations. Consequently, when the object of a preposition is questioned, only a prepositional phrase fragment answer, not a noun phrase fragment answer, is predicted to be fully acceptable. Both predictions were confirmed. The results support the claim that syntactic structure is present in unpronounced constituents, and tells against theories of syntax that eschew such structures.

It has been widely theorized and empirically proven that self-regulated learning is related to more desired learning outcomes, e.g., higher performance in transfer tests. Research has shifted to understanding the role of SRL during learning, such as the strategies and learning activities, learners employ and engage in the different SRL phases, which contribute to learning achievement. From a methodological perspective, measuring SRL using think-aloud data has been shown to be more insightful than self-report surveys as it helps better in determining (...) the link between SRL activities and learning achievements. Educational process mining on the basis of think-aloud data enables a deeper understanding and more fine-grained analyses of SRL processes. Although students’ SRL is highly contextualized, there are consistent findings of the link between SRL activities and learning outcomes pointing to some consistency of the processes that support learning. However, past studies have utilized differing approaches which make generalization of findings between studies investigating the unfolding of SRL processes during learning a challenge. In the present study with 29 university students, we measured SRL via concurrent think-aloud protocols in a pre-post design using a similar approach from a previous study in an online learning environment during a 45-min learning session, where students learned about three topics and wrote an essay. Results revealed significant learning gain and replication of links between SRL activities and transfer performance, similar to past research. Additionally, temporal structures of successful and less successful students indicated meaningful differences associated with both theoretical assumptions and past research findings. In conclusion, extending prior research by exploring SRL patterns in an online learning setting provides insights to the replicability of previous findings from online learning settings and new findings show that it is important not only to focus on the repertoire of SRL strategies but also on how and when they are used.

VP ellipsis generally requires a syntactically matching antecedent. However, many documented examples exist where the antecedent is not appropriate. Kehler, 533–575. 2002, Coherence, Reference and the Theory of Grammer, CSLI Publications. Stanford.) proposed an elegant theory which predicts a syntactic antecedent for an elided VP is required only for a certain discourse coherence relation, not for cause-effect relations. Most of the data Kehler used to motivate his theory come from corpus studies and thus do not consist of true minimal pairs. (...) We report five experiments testing predictions of the coherence theory, using standard minimal pair materials. The results raise questions about the empirical basis for coherence theory because a syntactically-matching antecedent is preferred for all coherence relations, not just resemblance relations. Further, strict identity readings, which should not be available when a syntactic antecedent is required, are influenced by parallelism per se, holding the discourse coherence relation constant. This draws into question the causal role of coherence relations in processing VP ellipsis. (shrink)

While there are many examples of metaphysical theorising being heuristically and intellectually important in the progress of scientific knowledge, many people wonder how metaphysics not closely informed and inspired by empirical science could lead to rival or even supplementary knowledge about the world. This paper assesses the merits of a popular defence of the a priori methodology of metaphysics that goes as follows. The first task of the metaphysician, like the scientist, is to construct a hypothesis that accounts for the (...) phenomena in question. It is then argued that among the possible metaphysical theories, the empirical evidence underdetermines the right one, just as the empirical evidence underdetermines the right scientific theory. In the latter case it is widely agreed that we must break the underdetermination by appeal to theoretical virtues, and this is just what should be and largely is done in metaphysics. This is part of a more general line of argument that defends metaphysics on the basis of its alleged continuity with highly theoretical science. In what follows metaphysics and theoretical science are compared in order to see whether the above style of defence of a priori metaphysics is successful. (shrink)

Environmental ethics has to deal with the challenge of reconciling contrasting ecocentric and animal-centric perspectives. Two classic attempts at this reconciliation, which both adopted the metaphor of concentric circles, are discussed. It is concluded that the relationship between the animal and its environment, whether the latter is human or natural, should be a pivotal element of such reconciliation. An alternative approach is presented, inspired by care ethics, which proposes that caring for wild animals implies caring for their relationship to the (...) natural environment and thus taking action to maintain wildlife habitat. This type of care is labelled non-specific care because it is not directed towards the individual wild animal and its specific individual needs. In contrast, caring for domestic animals is called specific care because it is much more directed towards the individual animal's needs. (shrink)

This paper draws on data from the most recent Australian Bureau of Statistics (ABS) Time Use Survey (TUS) (over 4,000 randomly selected households) to tease out the dimensions of the ‘second shift’. Predictions that as women entered the paid workforce men would contribute more to household labour have largely failed to eventuate. This underpins the view that women are working a second shift because they are shouldering a dual burden of paid and unpaid work. However, time use research seems to (...) show that when both paid and unpaid work is counted, male and female workloads are in total very similar. This has led to suggestions that a literal second shift is a myth; that it exists in the sense that women do more domestic work than men, but not in the sense that they work longer hours in total. Using a more accurate and telling measure of workload than previous research (paid and unpaid labour including multitasked activities), this paper explores the second shift and how it relates to family configuration, ethnicity and indicators of class and socioeconomic standing. It finds a clear disparity between the total workloads of mothers and fathers, much of which consists of simultaneous (secondary) activity, and some demographic differences in female (but not male) total workloads. It concludes that the view that the second shift is a myth is only sustainable by averaging social groups very broadly and by excluding multitasking from the measurement of total work activity.

When we are concerned with the logical form of a computation and its formal properties, then it can be theoretically described in terms of mathematical and logical functions and relations between abstract entities. However, actual computation is realised by some physical process, and the latter is of course subject to physical laws and the laws of thermodynamics in particular. An issue that has been the subject of much controversy is that of whether or not there are any systematic connections between (...) the logical properties of computations considered abstractly and the thermodynamical properties of their concrete physical realizations. Landauer [R. Landauer, Irreversibility and heat generation in the computing process, IBM Journal of Research and Development 5 183–191. Reprinted in Leff and Rex ] proposed such a general connection, known as Landauer’s Principle. To resolve this matter an analysis of the notion of the implementation of a computation by a physical system is clearly required. Another issue that calls for an analysis of implementation is that of realism about computation. The account of implementation presented here is based on the notion of an L-machine. This is a hybrid physical-logical entity that combines a physical device, a specification of which physical states of that device correspond to various logical states, and an evolution of that device which corresponds to the logical transformation L. The most general form of Landauer’s Principle can be precisely stated in terms of L-machines, namely that the logical irreversibility of L implies the thermodynamic irreversibility of every corresponding L-machine.

Conjointement, nous présentons trois-quatre artistes associés quant à leurs exigences et leur extrême volonté de continuer, et comme valeur architecturale (Barto & Barto), et comme valeur affranchie (Xatrec), et comme valeur contemporaine (Mathieu Mercier).

Supposant que l’art, après avoir été valuation, en était devenu l’intermédiaire, nous approchons deux modes qui peuvent générer sa fin ; d’une part, le savant raisonnement des faits artistiques qui en explicite et modélise les rouages et, corrélativement, l’exploitation systématique et marchande de toutes ses ressources émotionnelles… Tout en espérant, au bout du compte, que son essentielle inutilité de valeur sans terme lui sauve la mise.

Most discussions on animal experimentation refer to domesticated animals and regulations are tailored to this class of animals. However, wild animals are also used for research, e.g., in biological field research that is often directed to fundamental ecological-evolutionary questions or to conservation goals. There are several differences between domesticated and wild animals that are relevant for evaluation of the acceptability of animal experiments. Biological features of wild animals are often more critical as compared with domesticated animals because of their survival (...) effects. An important issue is what is called here ``natural suffering'''': the suffering from natural circumstances. Should this type of suffering be taken into account when suffering from experimentation is evaluated? As an answer, it is suggested that ``natural functioning'''' should be considered as an additional standard in the evaluation of wild animal experimentation. Finally, two topics related to the ecological context are considered. Firstly, the often inevitable involvement of non-research animals in wild animal experimentation, and secondly, the eco-centric approach to nature conservation. According to the latter position, animals are subordinated to ecosystems. All these aspects make the evaluation of wild animal experiments much more complex than experiments with domesticated animals. Preliminary scores are proposed to deal with these aspects. It is argued that this should not lead to a more complex governmental regulation, since an effective maintenance and control are hard to realize and one may loose the cooperation of researchers themselves. In addition, non-governmental professional organizations such as research societies and funding organizations play a pivotal role. (shrink)

I then describe the constructs of multiculturalism, and borders and ‘border thinking’ that become useful (...) to develop postcolonial readings as an active methodology of critique able to intervene and develops more revealing interpretations of some of science education's scholarship and differentiated experiences. As the focus of these interventions, I have selected to discuss Cobern and Loving's ‘Defining “Science” in a Multicultural World: Implications for science education’ and Siegel's ‘Multiculturalism, Universalism and Science Education: In search of common ground’ from the ongoing discussion on multiculturalism and cultural diversity within the journal Science Education.

Clinical decisions are expected to be based on factual evidence and official values derived from healthcare law and soft laws such as regulations and guidelines. But sometimes personal values instead influence clinical decisions. One way in which personal values may influence medical decision-making is by their affecting factual claims or assumptions made by healthcare providers. Such influence, which we call ‘value-impregnation,’ may be concealed to all concerned stakeholders. We suggest as a hypothesis that healthcare providers’ decision making is sometimes affected (...) by value-impregnated factual claims or assumptions. If such claims influence e.g. doctor–patient encounters, this will likely have a negative impact on the provision of correct information to patients and on patients’ influence on decision making regarding their own care. In this paper, we explore the idea that value-impregnated factual claims influence healthcare decisions through a series of medical examples. We suggest that more research is needed to further examine whether healthcare staff’s personal values influence clinical decision-making. (shrink)

Rodney Syme, retired medical doctor, urologist and advocate for medically assisted dying for 20 years, has helped scores of people die peacefully - people whose suffering has become unbearable to them. He takes on governments, the law and the medical profession. Most recently he won his challenge of an order by the Medical Board of Australia to prohibit him from doing anything that has the primary purpose of ending a person's life. The case in question was a 71-year-old man dying (...) of tongue and lung cancer whose life, the man said, was as miserable as hell. The Medical Board argued that the assistance in dying was a departure from accepted standards and presented a significant risk to that person. (shrink)
