Most scientific models are not physical objects, and this raises important questions. What sort of entity are models, what is truth in a model, and how do we learn about models? In this paper I argue that models share important aspects in common with literary fiction, and that therefore theories of fiction can be brought to bear on these questions. In particular, I argue that the pretence theory as developed by Walton (1990, Mimesis as make-believe: on the foundations of the (...) representational arts. Harvard University Press, Cambridge/MA) has the resources to answer these questions. I introduce this account, outline the answers that it offers, and develop a general picture of scientific modelling based on it. (shrink)

This is an extensive review of recent work on the foundations of statistical mechanics.

Entropy is ubiquitous in physics, and it plays important roles in numerous other disciplines ranging from logic and statistics to biology and economics. However, a closer look reveals a complicated picture: entropy is defined differently in different contexts, and even within the same domain different notions of entropy are at work. Some of these are defined in terms of probabilities, others are not. The aim of this chapter is to arrive at an understanding of some of the most important notions (...) of entropy and to clarify the relations between them, After setting the stage by introducing the thermodynamic entropy, we discuss notions of entropy in information theory, statistical mechanics, dynamical systems theory and fractal geometry.

A gas prepared in a non-equilibrium state will approach equilibrium and stay there. An influential contemporary approach to Statistical Mechanics explains this behaviour in terms of typicality. However, this explanation has been criticised as mysterious as long as no connection with the dynamics of the system is established. We take this criticism as our point of departure. Our central claim is that Hamiltonians of gases which are epsilon-ergodic are typical with respect to the Whitney topology. Because equilibrium states are typical, (...) we argue that there follows the desired conclusion that typical initial conditions approach equilibrium and stay there. (shrink)

GRW Theory postulates a stochastic mechanism assuring that every so often the wave function of a quantum system is `hit', which leaves it in a localised state. How are we to interpret the probabilities built into this mechanism? GRW theory is a firmly realist proposal and it is therefore clear that these probabilities are objective probabilities (i.e. chances). A discussion of the major theories of chance leads us to the conclusion that GRW probabilities can be understood only as either single (...) case propensities or Humean objective chances. Although single case propensities have some intuitive appeal in the context of GRW theory, on balance it seems that Humean objective chances are preferable on conceptual grounds because single case propensities suffer from various well know problems such as unlimited frequency tolerance and lack of a rationalisation of the principal principle.

On an influential account, chaos is explained in terms of random behaviour; and random behaviour in turn is explained in terms of having positive Kolmogorov-Sinai entropy (KSE). Though intuitively plausible, the association of the KSE with random behaviour needs justification since the definition of the KSE does not make reference to any notion that is connected to randomness. I provide this justification for the case of Hamiltonian systems by proving that the KSE is equivalent to a generalized version of Shannon's (...) communication-theoretic entropy under certain plausible assumptions. I then discuss consequences of this equivalence for randomness in chaotic dynamical systems. Introduction Elements of dynamical systems theory Entropy in communication theory Entropy in dynamical systems theory Comparison with other accounts Product versus process randomness. (shrink)

While e-commerce has witnessed extensive growth in recent years, so has consumers' concerns regarding ethical issues surrounding online shopping. The vast majority of earlier research on this area is conceptual in nature, and limited in scope by focusing on consumers' privacy issues. This study develops a reliable and valid scale to measure consumers' perceptions regarding the ethics of online retailers. Findings indicate that the four factors of the scale - security, privacy, non-deception and fulfillment/reliability - are strongly predictive of online (...) consumers' satisfaction and trust. The results offer important implications for e-retailers and are likely to stimulate further research in the area of e-ethics from the consumers' perspective. (shrink)

Various authors have argued that in the future not only will it be technically feasible for human minds to be transferred to other substrates, but this will become, for most humans, the preferred option over the current biological limitations. It has even been claimed that such a scenario is inevitable in order to solve the challenging, but imperative, multi-agent value alignment problem. In all these considerations, it has been overlooked that, in order to create a suitable environment for a particular (...) mind – for example, a personal universe in a computational substrate – numerous other potentially sentient beings will have to be created. These range from non-player characters to subroutines. This article analyzes the additional suffering and mind crimes that these scenarios might entail. We offer a partial solution to reduce the suffering by imposing on the transferred mind the perception of indicators to measure potential suffering in non-player characters. This approach can be seen as implementing literal empathy through enhanced cognition. (shrink)

Machine ethics and robot rights are quickly becoming hot topics in artificial intelligence and robotics communities. We will argue that attempts to attribute moral agency and assign rights to all intelligent machines are misguided, whether applied to infrahuman or superhuman AIs, as are proposals to limit the negative effects of AIs by constraining their behavior. As an alternative, we propose a new science of safety engineering for intelligent artificial agents based on maximizing for what humans value. In particular, we challenge (...) the scientific community to develop intelligent systems that have human-friendly values that they provably retain, even under recursive self-improvement. (shrink)

The stereotype content model defines warmth and competence as basic dimensions of social judgment, with warmth often dominating perceptions; it also states that many group-related stereotypes are ambivalent, featuring high levels on one dimension and low levels on the other. Persuasion theories feature both direct and indirect source effects. Combining both the approaches, we studied the persuasiveness of ambivalently stereotyped sources. Participants read persuasive arguments attributed to groups stereotyped as either low in competence but high in warmth or vice versa. (...) In Study 1, high competence/low warmth sources were more persuasive than low competence/high warmth sources. In Study 2, this pattern replicated when an accuracy motive had been induced, whereas it reversed when a connectedness motive had been induced. These source effects were direct, that is, independent of message processing. We discuss our findings in terms of the persuasiveness of warmth vs. competence of the source as being dependent on recipient motivation; we also consider theoretical implications and perspectives for future research.

There are many ontologies of the world or of specific phenomena such as time, matter, space, and quantum mechanics1. However, ontologies of information are rather rare. One of the reasons behind this is that information is most frequently associated with communication and computing, and not with ‘the furniture of the world’. But what would be the nature of an ontology of information? For it to be of significant import it should be amenable to formalization in a logico-grammatical formalism. A candidate (...) ontology satisfying such a requirement can be found in some of the ideas of K. Turek, presented in this paper. Turek outlines the ontology of information conceived of as a part of nature, and provides the ‘missing link’ to the Z axiomatic set theory, offering a proposal for developing a formal ontology of information both in its philosophical and logicogrammatical representations.

Some environmentalists have argued that an effective ecological conscience may be rooted in a perspective that is either anthropocentric or sentiocentric. But, neither seems to have had any substantial effect on the ways in which our species treats nature. In looking to successfully awaken the ecological conscience, the focus should be on extending moral consideration to the land (wherein doing so includes all of the soils, waters, plants, animals, and the collectivity of which these things comprise) by means of coming (...) to love the land. Coming to love the land involves coming to view the land’s interests as our own—and, conferring upon the land a kind of moral patient-hood. In order to perceive the land’s “subjectivity,” and so, to come to love the land, we must relearn the way to look at the land by viewing its personality through the lens of he or she who can already do so, i.e., the nature writer.

We prove a number of results concerning the variety of first-order theories and isomorphism types of pairs of the form $(N,M)$ , where $N$ is a countable recursively saturated model of Peano Arithmetic and $M$ is its cofinal submodel. We identify two new isomorphism invariants for such pairs. In the strongest result we obtain continuum many theories of such pairs with the fixed greatest common initial segment of $N$ and $M$ and fixed lattice of interstructures $K$ , such that $M\prec (...) K\prec N$. (shrink)

The current monopoly of psychology in the different facets of human life becomes psychological practice care increasingly suspect. And while it states legitimate targets, they are controversial. This paper highlights the lack of an agreed target between the professionals of psychological practice care. The first part argues that psychological practice care does not provide a clear and agreed target. This dissent is due to a disciplinary problem of psychology and it damages its image of responsible profession. In the second part, (...) we propose a goal that unifies various psychological practices care beyond their differences and through which its professional action is legitimate. The hypothesis presented is that the aim of psychological practice care is what begins it, that is, relief of suffering. However, to understand the nature of suffering, psychological practice care must regain its relationship with philosophy. (shrink)

Philosophical skepticism is identified by several signs or names: Aporētikoí, Ephektikoí, Pyrrhōneioi, Skeptikoí and Zētētikoí, with significant all of them valid and some confusion in meaning. The objective of this work is threefold: first, to clarify why some of these names have been more successful than others, second, what are the reasons why one of them has been fixed as a name, in general for all belonging to this philosophical movement, and third to what is due that recognizing the tradition (...) a clear initiator, Pirrón de Elis, and being the name "Pirrónicos" one of the most popular and one of the most used by the writers who speak about this movement, has not been the most successful, as it has been traditional in most other doctrines.

Este artículo tiene por objetivo retomar la teoría de Byung Chul Han sobre la sociedad del logro (Leistungsgesellschaft), tomando específicamente lo expuesto por él sobre el dogma de la transparencia que surge en la lógica neoliberal-digital contemporánea, para ser completado con la teoría freudiana de lo Unerkante -no reconocible-. Para esto el trabajo se divide en tres momentos: el primero tiene por objetivo exponer lo que se entiende por dogma de la transparencia y cómo se relaciona con el Homo œconomicus; (...) seguidamente, se presenta el concepto de lo Unerkante de Freud para plantear una nueva topología de lo no-reconocible en el plano subjetivo, proponiendo el concepto del ombligo de la subjetividad; y, finalmente, se expone cómo ese ombligo empalma con la teoría de Han frente a la transparencia, de modo que se puedan generar nuevas interpretaciones de lo que sería una salida a la sociedad del logro.

Although scholarship in philosophy of action has grown in recent years, there has been little work explicitly dealing with the role of time in agency, a role with great significance for the study of action. As the articles in this collection demonstrate, virtually every fundamental issue in the philosophy of action involves considerations of time. The four sections of this volume address the metaphysics of action, diachronic practical rationality, the relation between deliberation and action, and the phenomenology of agency, providing (...) an overview of the central developments in each area with an emphasis on the role of temporality. Including contributions by established, rising, and new voices in the field, _Time and the Philosophy of Action _brings analytic work in philosophy of action together with contributions from continental philosophy and cognitive science to elaborate the central thesis that agency not only develops in time but is shaped by it at every level.

The effects of time and the longitudinal course of the children’s internalizing symptoms following Intimate Partner Violence Exposure are still of great interest today. This study aimed to analyze the effect of the frequency of IPVE, adverse experiences after the cessation of the IPVE and the time elapsed since the termination of the violent relation on the prevalence of anxiety and depression among children. Participants were 107 children and their mothers who had been victims of IPV and had existing judicial (...) protection and restraining orders. Hierarchical logistic regression models were estimated to analyze children’s adjustment, considering the effect of the time elapsed since the termination, frequency of IPVE, experiences of revictimization, maternal pathology, and anxious anticipation of the mother at the prospect of future harm. Exposure to multiple events of violence at the hands of multiple ex-partners and higher scores in the mother’s anxious anticipation were significant predictors of children’s pathological depression and anxiety. Our results emphasize the need for early psychological evaluation of women and children’s victims of IPV to provide timely interventions that avoid symptoms from becoming chronic. Strategies to bring support and emotional security to the victims after the end of the violent relationship are desirable. (shrink)

The main idea of the article is that every belief is an answer to a question. Such question is called "calling the belief". It has a strictly assigned set of possible answers, such that they exclude one another. Understanding a belief means to know the question and all the alternative answers. Total ignorance of a question means that the curve that shows the level of affirmation of every possible answer is horizontal. Getting knowledge means folding the curve. Then some possibilities (...) become better affirmed then others. The possibility of folding the curve means that the question has empirical content. When one of the possibilities wins and becomes highly affirmed whereas others fall down to be rejected the subject obtains the truth. (shrink)
