People reject ‘paradoxical’ inferences, such as: Luisa didn't play music; therefore, if Luisa played soccer, then she didn't play music. For some theorists, they are invalid for everyday conditionals, but valid in logic. The theory of mental models implies that they are valid, but unacceptable because the conclusion refers to a possibility inconsistent with the premise. Hence, individuals should accept them if the conclusions refer only to possibilities consistent with the premises: Luisa didn't play soccer; therefore, if Luisa played a (...) game then she didn't play soccer. Two experiments corroborated this prediction for three sorts of ‘paradox’, including a disjunctive paradox. (shrink)
This study investigates whether the market valuation of the two summary accounting measures, book value of equity and net income, is higher for firms with reputation for sustainability leadership, when compared to firms that do not enjoy such reputation. The results are interpreted through the lens of a framework combining signalling theory and resource-based theory, according to which firms signal their commitment to sustainability to influence the external perception of reputation. A firm’s reputation for being committed to sustainability is an (...) intangible resource that can increase the value of a firm’s expected cash flows and/or reduce the variability of its cash flows. Our findings are according to expectations and show that the net income of firms with good sustainability reputation has a higher valuation by the market, when compared to their counterparts.

This study provides empirical evidence on how corporate sustainability performance (CSP), as proxied by membership of the Dow Jones sustainability index, is reflected in the market value of equity. Using a theoretical framework combining institutional perspectives, stake-holder theory, and resource-based perspectives, we develop a set of hypotheses that relate the market value of equity to CSP. For a sample of North American firms, our preliminary results show that CSP has significant explanatory power for stock prices over the traditional summary accounting (...) measures such as earnings and book value of equity. However, further analyses suggest that we should not focus on corporate sustainability itself. Our findings suggest that what investors really do is to penalize large profitable firms with low level of CSP. Firms with incentives to develop a high level of CSP not engaging on such strategy are, thus, penalized by the market. (shrink)
In this essay, I have rejected the inductive interpretation of the paradigm of contextual implication (to say “p”; is to imply that one believes that ) and proposed in its stead an explicatory model according to which a speaker in making a statement contextually implies whatever one is entitled to infer on the basis of the presumption that his act of stating is normal. In developing this model, I show how contextual implication depends on three distinct matters: a stating context, (...) presumptions of normality, and rules for the correct use of expressions.

The multifaceted nature of empathy requires a comprehensive conceptualization of core and related emotional and mindreading processes. Here I argue that new paradigms are needed that allow for a more ecologically valid and parametric assessment of empathy subprocesses and their neuronal correlates. Towards that goal, cognitive neuroscience studies should make use of audiovisual stimuli that more closely approximate real-life settings and include online social interaction paradigms.
En este trabajo se analizan, por una parte, los datos sobre la presencia de las mujeres en los movimientos de derechos de los animales en el estado español; por otro lado, tratamos de encontrar marcos explicativos que aclaren cuál es el vínculo que conecta la sensibilidad feminista con la sensibilidad animalista. Hemos realizado un sondeo sobre el porcentaje de mujeres entre los miembros de las organizaciones animalistas más importantes de España y, con estos resultados, hemos hecho una revisión de los (...) diferentes marcos teóricos que pueden explicar esta significativa orientación de género en la defensa del bienestar animal. Por último, defendemos que hay un vínculo entre la ideología patriarcal y la explotación ecológica, en tanto que ambos comparten la dominación y la opresión de género. En este sentido, la sensibilidad animalista movilizaría sentimientos morales de fraternidad con la naturaleza. (shrink)
The current work builds a definition of irritability from both academic definitions and lay perspectives. In Study 1, a quantitative content analysis of academic definitions resulted in eight main content categories. In Study 2, a community sample of 39 adults participated in qualitative interviews. A deductive thematic analysis resulted in two main themes. The first main theme dealt with how participants positioned irritability in relation to other negative states. The second dealt with how participants constructed irritability as both a loss (...) of control and as an experience that should be controlled. The discussion integrates the findings of both studies and provides a concise, but comprehensive definition. (shrink)
Con base en una investigación de la obracompleta de Feuerbach, se buscan los matices de Incomprensión feuerbachiana del materialismo a lo largo de la evolución de su pensamiento. En contra de los dualismos exaltados, Feuerbach quiere fundar un materialismo antropológicoy racional, en el marco delreconocimiento de la Naturaleza, de la intuición y del amor. Desde el punto de vista ontológico, queda, sin embargo, en cierto modo, abierta la cuestión de si ese materialismo es consecuente, sobre todo en lo que respecta (...) al papel de la praxis y de la subjetividad como condición de posibilidad de la materialidad.

Marcuse teve no Brasil na década de 1970 uma recepção unilateral, sendo visto unicamente como guru da contra-cultura. Contra esse equívoco o artigo mostra a relação intrínseca entre teoria e prática na filosofia de Marcuse, caracterizada como uma filosofia política cuja preocupação central é a transformação radical da sociedade capitalista.
This paper gives an implicit characterization of the class of functions computable in polynomial space by deterministic Turing machines – PSPACE. It gives an inductive characterization of PSPACE with no ad-hoc initial functions and with only one recursion scheme. The main novelty of this characterization is the use of pointers to reach PSPACE. The presence of the pointers in the recursion on notation scheme is the main difference between this characterization of PSPACE and the well-known Bellantoni-Cook characterization of the polytime (...) functions – PTIME.

Resource rationality may explain suboptimal patterns of reasoning; but what of “anti-Bayesian” effects where the mind updates in a direction opposite the one it should? We present two phenomena — belief polarization and the size-weight illusion — that are not obviously explained by performance- or resource-based constraints, nor by the authors’ brief discussion of reference repulsion. Can resource rationality accommodate them?
In this article, we examine the role of several consumers’ cognitive and psychographic traits in their perceptions of retailers’ deceptive practices and the different effects on perceived deception associated with online vis-à-vis in-store shopping. Building on theoretical models of persuasion in consumer behavior, we hypothesize that the antecedents of perceived deception in traditional settings are the same as those on the Internet, while the intensity of the impact of these antecedents differs between the online and the offline environment. Results suggest (...) that the effects of individual’s cognitive traits and risk aversion on perceived deception are more relevant when consumers shop online than when they purchase from traditional stores. Conversely, psychographic traits play a more important role in explaining perceived deception in the traditional shopping context as compared to the online channel. Several theoretical and managerial implications are derived from these findings. (shrink)
In part through correcting mistranslations of key passages in the "de logica" part of his "de corpore," hobbes is shown to have held a theory in which the intention to communicate enters into the definition of signification; and in which speech requires, In addition, (1) socially agreed-Upon correlations between kinds of utterances and kinds of things, And (2) an interrelationship of such utterances (or 'words') in what hobbes calls 'contexture'. It is shown that hobbes did not hold that for a (...) linguistic expression to have meaning is for it to stand for something, Or that what an expression means is what it stands for--Positions commonly, And mistakenly, Attributed to him.

In the first part of this article, we show that, contrary to the Gricean tradition, inter-clausal and is not semantically equivalent to logical conjunction and, contrary to temporal approaches such as Bar-Levand Palacas 1980, it is not temporallyloaded. We then explore a commonsenseidea – namely that while sentence juxtaposition might be interpreted either as discourse coordination or subordination, and indicates coordination. SDRT already includes notions of coordinating and subordinating discourse relations (cf. Lascarides and Asher 1993, Asher 1993), and the meaning (...) of and is related to this distinction. Similar distinctions that play a crucial role in anaphora resolution have also appeared in AI – cf. Scha and Polanyi 1988, or Webber 1991. However, this discourse-structure-based distinction has not been well defined yet, and our approach provides independent motivation for it. This paper argues that the semantics of and includes a notion of coordination expressed as the requirement of a Coordinated Discourse Topic (CDT).CDT characterizes aclass of discourse relations, among which are Narration and Result.Once the basic semanticcontribution of and is isolated, effects related to its presence such as changes in temporal structure, blocking of a Discourse Relation, or conditional meanings are shown to follow from the defeasiblearchitecture set up by SDRT.

Joseph Priestley, the eighteenth-century scientist who discovered oxygen, was one of the most remarkable thinkers of his time. This collection of essays by a team of experts covers the full range of his work in the fields of education, politics, philosophy, and theology, and firmly re-establishes him as a major intellectual figure.
Higher Order theories of consciousness have their fair share of sympathisers, but the arguments mustered in their support are—to my mind—unduly persuasive. My aim in this paper is to show that Higher Order theories cannot accommodate the possibility of misrepresentation without either falling into contradiction, or collapsing into a First-Order theory. If this diagnosis is on the right track, then Higher Order theories—at least in the specific versions here considered—fail to give an account of what they set out to explain: (...) what is distinctive of ‘conscious’ phenomena.

Like many humans in the wake of genocide and war, most wildlife today has sustained trauma. High rates of mortality, habitat destruction, and social breakdown precipitated by human actions are unprecedented in history. Elephants are one of many species dramatically affected by violence. Although elephant communities have processes, rituals, and social structures for responding to trauma—grieving, mourning, and socialization—the scale, nature, and magnitude of human violence have disrupted their ability to use these practices. Absent the cultural, carrier groups who traditionally (...) lead and teach these healing practices, humans must assume the role. Trauma theory has brought attention to victims' severe, sustained psychological damage. Looking through the lens of trauma theory provides a better understanding of how systematic violence has affected individuals and groups and how the pervasive nature of traumatic events affects human-nonhuman animal relationships. The framing of recent trauma theory compels conservationists to create new relationships—neither anthropocentric nor powerbased—with nonhuman animals. The David Sheldrick Wildlife Trust, Kenya, shows how humans, taking on the role of interspecies witness, bring orphan elephants back to health and help re-build elephant communities shattered by genocide.

A two-sorted term system characterizing NC implicitly is described. The term system is defined over the tree algebra [MATHEMATICAL DOUBLE-STRUCK CAPITAL T], the free algebra generated by 0, 1 and ∗, and the recursion scheme uses pointers over tier 0. This differs from previous characterizations of NC, where tier 1 pointers were used or full parameter substitution over tier 0 was allowed.
Consumer distrust is only recently beginning to be perceived as an important e-commerce issue and, unlike online trust, the nature and role of distrust is much less established. This study examines the influence of two important consumer characteristics on consumer’s ethically-based distrust of online retailers. Also, the moderating role of consumer’s need for personal contact with sales staff is tested. Results from 409 online consumers confirm that both relativist-based ethical ideology and risk aversion are strongly and positively related to consumers’ (...) distrust. Interestingly, our findings show that positive effects of relativism and risk aversion on consumer’s distrust are moderated by consumers’ need for personal interaction, which is more pronounced for those consumers with a high need for personal interaction with retail salespeople.

Summary This article looks at a specific case of intellectual exchange by approaching Luís Pereira Barreto (1840?1923), a Brazilian medic who, having studied in Brussels in the 1850s, came into contact with Comte's positivism and with the ideas of his disciples. While in Europe, Barreto established a long-lasting friendship with Pierre Lafitte, and became a convert to Comte's Religion of Humanity. Upon his return to Brazil in 1864, Barreto sought to apply Comte's principles to Brazilian society and politics. Although Barreto's (...) use of positivism extends beyond the issue of slavery and slave work, I will focus on this priest of humanity's considerations about positivism, social evolutionism, and Brazilian slavery. This will allow me to extrapolate some qualified conclusions about the nature of the intellectual exchange that occurred between Barreto and the French positivists, and the development of Brazilian positivism as a political philosophy and social theory which had to address the problem of slavery in the 1870s and 1880s.
