Complex student models often include key parameters critical to their behavior and effectiveness. For example, one meta-cognitive model of student help-seeking in intelligent tutors includes 15 rules and 10 parameters. We explore whether or not this model can be improved both in accuracy and generalization by using a variety of techniques to select and tune parameters.We show that such techniques are important by demonstrating that the normal method of fitting parameters on an initial data set generalizes poorly to new test (...) data sets. We then show that stepwise regression can improve generalization, but at a cost to initial performance. Finally, we show that causal search algorithms can yield simpler models that perform comparably on test data, but without the loss in training set performance. The resulting help-seeking model is easier to understand and classifies a more realistic number of student actions as help-seeking errors. (shrink)

While stakeholder theory has traditionally considered organization’s interactions with stakeholders in terms of independent, dyadic relationships, recent scholarship has pointed to the fact that organizations exist within a complex network of intertwining relationships [e.g., Rowley, T. J.: 1997, The Academy of Management Review 22(4), 887–910]. However, further theoretical and empirical development of the interactions between stakeholders has been lacking. In this paper, we develop a framework for understanding and measuring the effects upon the organization of competing, complementary and cooperative stakeholder (...) interactions, which we refer to as stakeholder multiplicity. We draw upon three forms of fit (i.e. fit as matching, fit as moderation, and fit as gestalts; Venkatraman, N.: 1989) to develop a framework for understanding stakeholder multiplicity based upon the direction, strength, and synergies of the interacting claims. Additionally, we draw upon the theory of stakeholder identification and salience of Mitchell et al. (1997), which we argue provides a more relevant and significantly more illustrative explanation of the nature and effects of stakeholder interactions upon the organization than the network approach of Rowley (1997). Furthermore, we ground our framework through reference to three stakeholder groups (i.e. governments, customers, and employees) and the stakeholder issue of concern for the natural environment. We propose a hierarchy of the multiplicity strength of influence of these three stakeholder groups. Potential measurement and implications are discussed. (shrink)

Most proponents of conscientious objection accommodation in medicine acknowledge that not all conscientious beliefs can justify refusing service to a patient. Accordingly, they admit that constraints must be placed on the practice of conscientious objection. I argue that one such constraint must be an assessment of the reasonability of the conscientious claim in question, and that this requires normative justification of the claim. Some advocates of conscientious object protest that, since conscientious claims are a manifestation of personal beliefs, they cannot (...) be subject to this kind of public justification. In order to preserve an element of constraint without requiring normative justification of conscientious beliefs, they shift the justificatory burden from the belief motivating the conscientious claim to the condition of the patient being refused service. This generally involves a claim along the lines that conscientious refusals should be permitted to the extent that they do not cause unwarranted harm to the patient. I argue that explaining what would constitute warranted harm requires an explanation of what it is about the conscientious claim that makes the harm warranted. ‘Warranted’ is a normative operator, and providing this explanation is the same as providing normative justification for the conscientious claim. This shows that resorting to facts about the patient’s condition does not avoid the problem of providing normative justification, and that the onus remains on advocates of conscientious objection to provide normative justification for the practice in the context of medical care.

The paper focusses on two claims about metaphysical structure: Atomism and Fundamentalism. The first of these claims says that there are mereological atoms, i.e. minimal elements in the mereological structure of reality. The second says that there are fundamental truths, i.e. minimal elements in the grounding structure of reality. A philosopher who defended both of these claims was Bernard Bolzano; the present paper is an exploration of his views on the matter.

This review essay looks at Andrew Brei’s edited volume, Ecology, ethics and hope, Candis Callison’s How climate change comes to matter: The communal life of facts, Randall Curren and Ellen Metzger’s Living well now and in the future: Why sustainability matters, Willis Jenkins’ The future of ethics: Sustainability, social justice, and religious creativity, and Byron Williston’s The Anthropocene project: Virtue in the age of climate change. These recent works highlight various normative approaches for engaging with what is often referred to (...) as the Anthropocene. Drawing on virtue ethics, pragmatism, and concepts such as intergenerational justice, they seek to address some of the defining moral challenges of our time: how we should respond to this unprecedented era of anthropogenic climate and environmental change, and what ethical resources we can draw on to guide our response. On a larger level, they reveal how the climate crisis is testing the limits of our current moral systems and helping to drive greater ethical innovation and adaptation in the process. (shrink)

As academic literatures and political demands, global justice and populism look like competing ways of diagnosing and addressing neoliberal inequality. But both misunderstand neoliberalism and consequently risk reinforcing rather than undermining it. Neoliberalism does not just break down political and social hierarchies, but also relies on and sustains them. Unless populists recognize this, they will find that assertions of sovereignty do more to reinforce neoliberalism and reproduce its hierarchies than to resist them. Recognizing neoliberalism as not simply corrosive of solidarity (...) but also producing its own affective ties suggests that global justice advocates need to develop a critique of individual attitudes that egalitarian liberals have often seen as private and been hesitant to judge. In short, if either populism or global justice hope to take advantage of neoliberalism’s failures to advance an egalitarian politics, they need to reckon more carefully with their own entanglement with neoliberalism’s hopes and hierarchies.

This article defends the normative relevance of the representation of non-citizens in democracies. I argue that representation within nation-states constitutes a realistic institutionalisation of the All-Affected Principle, allowing justificatory practices towards non-citizens and establishing political institutions that can realise the ideal of inclusion of all externally affected individuals. I defend electoral, non-electoral and surrogate forms of representation of affected interests that satisfy both the cosmopolitan concern for the equal consideration of interests and the statist defence of the importance of a (...) territorially and civically bounded demos. I assess piecemeal implementations of representation practices, namely reciprocal representation, ombudspersons, self-appointed representatives and deliberative and advocacy groups. Gradual and pluralised means of representation constitute necessary and feasible first steps to consider affected interests and offer an alternative route to an all-or-nothing defence of inclusion as national enfranchisement.

It is shown that the standard definitions of truth-functionality, though useful for their purposes, ignore some aspects of the usual informal characterisations of truth-functionality. An alternative definition is given that results in a stronger notion which pays attention to those aspects.

In Plato’s Euthyphro, Euthyphro proposes to analyse the pious as that which is beloved of the gods. In the most widely discussed argument of the dialogue, Socrates tries to show that Euthyphro’s analysis fails. The argument crucially involves an ingenious use of the explanatory connective ‘because’. This paper presents a detailed reconstruction and defence of the argument. It starts with a rigorous analysis of its logical form, explains and justifies its premises, and closes with a defence of the argument against (...) the strongest common objection. (shrink)

In this paper I argue that even if one accepts non-cognitivism about trust, the view that trust is not a species of and does not require belief, one should reject voluntarism about trust, the view that we can trust directly at will. There is good reason to think that we cannot trust directly at will, in the way that we can act, and this is so regardless of whether trust requires belief.

This work inaugurates a critical inquiry into whether the ideas of Karl Popper, a philosopher of science, are used by astronomers and astrophysicists, a practicing community of scientists. It examines four basic components of Karl Popper's philosophy— falsification, prohibition, simplicity, and risk taking— and the extent that these themes become integrated into recent scientific literature on astronomy, astrophysics, cosmology, and stellar evolutionary theory. It concludes that the philosophy of science is highly relevant to the practice of astronomy, and that Karl (...) Popper plays a unique role in directing different communities of astronomers and cosmologists. (shrink)

Discussion of the need for moral guidelines in business; suggestions for communication in the workplace.

The way in which philosophers have thought about the scientific method and the nature of good scientific reasoning over the last few centuries has been consistently and heavily influenced by the examples set by physics. The astounding achievements of 19th and 20th century physics demonstrated that physicists had successfully identified methodologies and reasoning patterns that were uniquely well suited to discovering fundamental truths about the natural world. Inspired by this success, generations of philosophers set themselves the goal of taxonomising, codifying, (...) formalising and evaluating these reasoning patterns. Many will concede that this has been a tremendously fruitful exercise that has served both to illuminate characteristic methodological and epistemological features of the physical sciences, and to inform the way that philosophers think about the epistemic ideals served by science more generally. However, as has been widely noted, the great challenges confronted by contemporary physics have led to a number of fundamental shifts in the way that physicists formulate, assess and apply their theories of the physical world. The most prominent examples of this trend occur in the realm of theoretical high energy physics, where many of the most influential theories advocated by physicists lie beyond the reach of extant experimental methods, and are therefore extremely difficult to test empirically. The fact that whole communities of physicists have devoted so much time and effort to evaluating theories that are largely disconnected from experiments and empirical testing suggests that existing philosophical accounts of the epistemology of physics, based as they are on a broadly empiricist conception of physics, are no longer completely apt, or are at least somewhat out of date. This in turn suggests that it is time for philosophers to redirect their attention towards the characteristic reasoning strategies at play in contemporary physics. As well as clarifying the epistemic structure of 21st century physics and providing new stimulation for general debates surrounding the epistemology of science, this will also allow more philosophers to confront and engage with the existential methodological debates currently raging within physics. There is currently intense and wide spread disagreement surrounding what kinds of reasoning strategies can legitimately be employed in the assessment of competing physical theories and research programs. This special issue aims to facilitate the further engagement of philosophers in this crucial debate by collecting eight contributions that both highlight the deep philosophical issues at stake in debates surrounding the proper methodology for theory assessment in physics, and present novel philosophical perspectives on specific reasoning strategies in the physical sciences.

To establish phenomenologically whether there is an everyday dimen­sion within the “sub-world” of science, this paper builds on Richard Grathoff’s conceptual differentiation between “lifeworld” (Lebenswelt), “everyday world” (Alltagswelt), and “daily life” (Alltägliches Leben). Such a clarification is necessary because the notion of “lifeworld” in Husserl’s or Schutz’ oeuvre is ambiguous. It means both a universal ground and an everyday world. According to Grathoff, the lifeworld is a set of general and structural dimensions of sense that relate subjectivity and world-structure and (...) thereby make possible the constitution of specific “worlds,” including the everyday world. The latter, in contrast, exists due to its own cognitive style according to which lifeworldly dimensions become senseful. Still different from the everyday world is daily life, the routin­ized process through which certain qualities of the various cognitive styles are socially constructed. Grathoff’s distinction helps to identify an internal quality within science, which includes, on the one hand, the scientific “daily life” of routine and familiarity, such as basic methods and epistemes, and, on the other hand, needs to be understood in terms of “contextualization” (Strassheim), as a realm of the new and “extraordinary,” as in far-reaching theorizing efforts.

Abstract The role of actual works of art with philosophical writing is often reduced to the status of example or illustration. As such the materiality of art work is rarely discussed let alone deployed as the basis of philosophical reflection. In this paper works by Francesco Mosca, and Bernini are used to question Heidegger's writings on sculpture. What such an approach opens up is the possibility that art may set the measure for philosophy.

When business organisations become involved in contributing to and resolving social issues, they enter areas traditionally seen as the purview of governments. In doing so, they begin to take on the expectations and responsibilities of government; they become politicised. This politicisation is a product of business’s success and power and appears largely unavoidable. Adopting Matten & Crane’s (2005a) extended view of corporate citizenship, business organisations’ responsibilities extend to the administration of citizens’ social, civil and political rights. We term these areas (...) where business organisations take over the administration of citizenship rights as the social governance gap. Drawing upon the agenda of Margolis and Walsh (2003), we seek to enhance the understanding of how business navigates its responsibilities within the social governance gap, including its function as a significant actor influencing societal development and wellbeing. We do this through an exploration of Rio Tinto’s involvement in the WA Future Fund. This paper forms part of an introductory scoping case study of the Rio Tinto WA Future fund and its function as one of Rio Tinto’s diverse responses to community development issues in Western Australia.

In this essay, I offer an interpretation of the ethical thought of Elizabeth Anscombe, Philippa Foot, Mary Midgley, and Iris Murdoch. The combined effect of their work was to revive a naturalistic account of ethical objectivity that had dominated the premodern world. I proceed narratively, explaining how each of the four came to make the contribution she did towards this implicit common project: in particular how these women came to see philosophical possibilities that their male contemporaries mostly did not.

Many philosophers today accept the broadly Aristotelian view that one can explain de re necessary properties by invoking essence. These ‘Neo-Aristotelian essentialists’ hold that a property F is an essential property of x iff specifying F gives a correct answer to the Aristotelian ‘what is x?’ question. We are sceptical. According to neo-Aristotelian essentialists, essential properties are not themselves de re modal properties, but they are supposed to explain why things have their de re modal properties. Neo-Aristotelian essentialists accept the (...) following principle (ENL): If x is essentially F, then x is necessarily F. We ask: Why? We first clarify the neo-Aristotelian notion of essence via the Aristotelian “what is x?” question. So far as we can see, the only way to do this is by appeal to the notion of a substance sortal. We then consider the notion of a substance sortal itself, and argue that there is nothing in that notion that even so much as suggests that ENL is true. (shrink)

Derek Bolton has claimed that extant philosophical theories of mind imply accounts of mental disorder, via their accounts of intentionality. The purpose of this paper is to extend Bolton’s claims, by exploring what an embodied/situated theory of mind might imply about mental disorder. I argue that, unlike the more traditional views Bolton considers, embodied/situated accounts can (in principle) provide an observer-independent criterion for distinguishing mental health from disorder in cases of Capgras and Cotard delusions.

Read Jus, 17 June 1887): The voluntary taxation proposal really means the dissolution of the State into its constituent atoms, and leaving them to recombine in some way or no way, just as it may happen.

The proposal is, it appears to me, the outcome of an idea in the minds of those (...) who propound it that the State is, or ought to be, founded on contract, just as a joint stock company is. ...

Synthetic meat products promise to serve as inexpensive substitute proteins that can replace meat made through conventional animal agriculture. At least some of the excitement about these products stems from ethical and moral concerns regarding animal welfare, environmental costs, and human health. A governing idea behind the creation of substitute meat is that consumers will recognize the ethical and moral concerns of conventional production and substitute one (better) product for another (worse) product. This approach, however, overlooks a much more practical (...) complication: the problem of indifference. That is,--consumer demand does not in practice greatly hinge on the well-known moral issues in conventional animal agriculture, as evident by the immense scale of the current meat market. In this paper, we ask how consumer indifference and producer strategy might influence the uptake of clean meat in the economic market. We suggest that thinking about the challenge in this way reveals powerful presuppositions that confuse our thinking about the potential of synthetic meat. Rather than understanding synthetic meat in terms of its substitution value, we propose approaching the challenge of synthetic meat from the standpoint of reasons-for and reasons-against. Doing so, we suggest, exposes the complications of “causal indeterminacy” that in turn implicate our thinking both about moral responsibility and the broader nature of technocratic solutions to environmental problems. We argue instead that synthetic meat offers an exciting and novel product, but likely not a substitute that will displace the conventional protein industry. (shrink)

The modern state is often taken as the only legitimate claimant to the division of the globe. Political theorists offer many theories of territorial rights but tend to agree that the state remains the proper institutional bearer of such rights. This article examines how states became the exclusive bearers of territorial rights by returning to the international theory of the eighteenth-century Prussian jurist Christian Wolff (1679–1754), who wrote in a moment when sovereign states were not the heirs apparent to the (...) globe but competed with other claimants to territorial rights. Despite proposing a radically pluralistic and anti-imperial account of land ownership, Wolff nonetheless paved the way for the state to become the sole bearer of territorial rights. Wolff’s international thought is an illustration of how building a state-centric international order was a double-edged sword: it criticized imperial overreach while also closing the international arena to nonstate forms of collective life. In this process, he offered two distinct ideas of political space: the territorial space of states, and the land ownership tracts of nonstate peoples, including pastoralists and nomads. To Wolff, only states were entitled to full and permanent territorial rights, while nonstate peoples were shut out of the international system, made both de facto and de jure stateless. (shrink)

We investigated the accuracy of gender stereotypes regarding digital game genre preferences. In Study 1, 484 female and male participants rated their preference for 17 game genres (gender differences). In Study 2, another sample of 226 participants rated the extent to which the same genres were presumably preferred by women or men (gender stereotypes). We then compared the results of both studies in order to determine the accuracy of the gender stereotypes. Study 1 revealed actual gender differences for most genres—mostly (...) of moderate size. Study 2 revealed substantial gender stereotypes about genre preferences. When comparing the results from both studies, we found that gender stereotypes were accurate in direction for most genres. However, they were, to some degree, inaccurate in size: For most genres, gender stereotypes overestimated the actual gender difference with a moderate mean effect size. (shrink)
