This paper addresses a variant of the job shop scheduling problem with total tardiness minimization where task durations and due dates are uncertain. This uncertainty is modelled with intervals. Different ranking methods for intervals are considered and embedded into a genetic algorithm. A new robustness measure is proposed to compare the different ranking methods and assess their capacity to predict ‘expected delays’ of jobs. Experimental results show that dealing with uncertainty during the optimization process yields more robust solutions. A sensitivity (...) analysis also shows that the robustness of the solutions given by the solving method increases when the uncertainty grows. (shrink)

Esta obra se concentra en cuatro temas cruciales de la formación de docentes, tanto antes como durante el servicio y en la enseñanza en diferentes áreas y niveles educativos. En primer lugar, se aborda el asunto de las creencias que los docentes tienen sobre el proceso educativo, las cuales parecen influir en la práctica profesional que estos desarrollan y, por lo tanto, deberían recibir la atención explícita de los procesos de formación de docentes que deseen promover prácticas específicas. El segundo (...) tema de la obra es la relación entre la formación de docentes y la política pública que la rige. En particular, se analizan las reformas curriculares implementadas por varias licenciaturas en universidades privadas colombianas, en respuesta a reformas a la normatividad sobre las condiciones de calidad que a las que deben ajustarse todas las licenciaturas del país. El tercer tema analizado es en qué medida los docentes en educación superior van más allá del dominio de su saber disciplinar atribuyendo importancia a la pedagogía, la didáctica y la práctica reflexiva en su propia práctica docente. Finalmente, se discuten aspectos de la formación de docentes relacionados con los procesos vividos y los retos encontrados por los docentes al entrar en la profesión, su socialización en la comunidad docente, sus identidades como maestros y su motivación para ser docentes. Vale la pena señalar que las contribuciones a este libro comparten el uso de metodologías cualitativas y presentan los resultados de historias de vida, entrevistas, observaciones, y análisis documentales, entre otros.

Co-authored research paper written with José Vela Castillo on the subject of Pablo Román's wall of 1,000 images, Vienna, 2013. -/- “Vienna” or “The Wall” is an ongoing project by architect/artist Pablo Román that, upon its completion, will consist of the round number of 1,000 images taped onto an off-white wall. One of the many walls he has designed/produced in the past months (architectural or otherwise), its elementary condition is at the same time enhanced and diminished by its (...) very presence as wall-cum-images, or as images-out-of-a-wall, eroding its foundational condition to a flickering-tele-techno-pixelated spectral apparatus. Its radically modern and outdated presence reconfigures contemporary reflections on what architecture and what the modern is, indirectly referencing “Fundamentals,” the 2014 Venice Architecture Biennale curated by Rem Koolhaas.

To the sceptic's contention that I don't know that I have hands because I don't know that there is an external world, the Moorean replies that I know that there is an external world because I know that I have hands. Crispin Wright has argued that the Moorean move is illegitimate, and has tried to block it by limiting the applicability of the principle of the transmission of knowledge by inference—the principle that recognising the validity of an inference from known (...) premises generates knowledge of the conclusion. I argue that, in the presence of some plausible assumptions, blocking the Moorean move does not require limiting the applicability of the transmission principle. Then I argue against Jim Pryor's contention that the Moorean argument transmits evidential support from its premises to its conclusion. (shrink)

The paper deals with the interpretation of Wittgenstein's views on the power of occurrent mental states to sort objects or states of affairs as in accord or in conflict with them, as presented in the rule-following passages of the Philosophical Investigations. I shall argue first that the readings advanced by Saul Kripke and John McDowell fail to provide a satisfactory construal of Wittgenstein's treatment of a platonist account of this phenomenon, according to which the sorting power of occurrent mental states (...) is to be explained by reference to the mind's ability to grasp universals. I contend that the argument that Kripke extracts from Wittgenstein's discussion doesn't succeed in undermining the platonist position. Then I argue that McDowell's reading exhibits a more serious shortcoming: the position that he ascribes to Wittgenstein is indistinguishable from the platonist account. Then I put forward a proposal as to how to articulate the relationship between Wittgenstein's views and the platonist position. (shrink)

An introduction to the basic concepts and results of contemporary logic, including a discussion of the basic mathematical tools needed to master the technical aspects of the subject.

The paper develops an account of semantic notions which occupies a middle ground between antirealism and traditional forms of realism, using some ideas from the work of John McDowell. The position is based on a contrast between two points of view from which we might attempt to characterize our linguistic practices from the cosmic exile s point of view and from the midst of language as a going concern. The contrast is drawn in terms of whether our characterization of our (...) linguistic practices is taken to result from engagement in the very same practices that we are trying to characterize. The position takes realism to be correct when understood as an account from the internal perspective, but incorrect when taken as an account from the external perspective. However, the intelligibility of the question as to what our practices would look like from the cosmic exile s point of view is presented as problematic. (shrink)

I use some ideas of Keith DeRose's to develop an (invariantist!) account of why sceptical reasoning doesn't show that I don't know that I'm not a brain in a vat. I argue that knowledge is subject to the risk-of-error constraint: a true belief won’t have the status of knowledge if there is a substantial risk of the belief being in error that hasn’t been brought under control. When a substantial risk of error is present (i.e. beliefs in propositions that are (...) false in nearby worlds), satisfying the constraint requires bringing the risk under control. This is achieved either by sensitivity, i.e. you wouldn’t have the belief if it were false, or by identifying evidence for the proposition. However, when the risk of error is not substantial (i.e. beliefs in propositions that are not false in nearby worlds), the constraint is satisfied by default. My belief that I am not a brain in a vat is insensitive and I have no evidence for it, but since it is not false in nearby worlds, it satisfies the constraint by default. (shrink)

Reliabilist accounts of knowledge are widely seen as having the resources for blocking sceptical arguments, since these arguments appear to rely on assumptions about the nature of knowledge that are rendered illegitimate by reliabilist accounts. The goal of this book is to assess the main arguments against the possibility of knowledge, and its conclusions challenge this consensus. The book articulates and defends a theory of knowledge that belongs firmly in the truth-tracking tradition, and argues that although the theory has the (...) resources for blocking the main standard lines of sceptical reasoning, there is a sceptical argument against which the theory offers no defence, as it doesn’t rely on any assumptions that the theory would render illegitimate. The book ends with the suggestion that the problem might have a metaphysical solution—that although the sceptical argument may make no illegitimate epistemological assumptions, it does rest on a questionable account of the nature of cognition.

There is a question that has not been raised in the literature on Japan's regionalism: Why does it have a strong tendency toward making the boundary of the proposed East Asian community fluid? By looking back beyond the Greater East Asia Co-Prosperity Sphere of the 1940s, a method hitherto untried, the paper shows that this Japanese propensity was also present in the first half of the twentieth century, especially in the 1920s and 1930s. Moreover, both then and now, Japan did (...) not and does not have a firm adherence to an ideology. These are two similarities between the pre-World War II period and the present (from the 1960s). On the other hand, Japan's present international situation is very different from its pre-World War II position. The paper uses the logic of the comparative method, which states that in two cases that are different in most aspects but the same in some, one or some of the similarities may explain the other similarity or similarities. It concludes that in both periods, the lack of a firm commitment to an ideology explains Japan's prejudice toward boundary fluidity. This explanation has the potential to contribute to a more comprehensive, if not yet a general theory of Japan's approach to regionalism because it applies not only to the present, but to the past as well. And it has to be stressed, the past refers not only to the Greater East Asia Co-Prosperity Sphere of the 1940s but also to the decades before. (shrink)

An account of predicate reference is presented which attempts to steer a middle course between reductionism, which construes the notion in terms of speakers' inclinations, and {transcendent) realism, which construes the notion in terms of properties. It is first introduced in the context of a discussion of the accounts of length (distance) advanced by Hans Reichenbach, Adolf Grünbaum and Hilary Putnam. A general account of predicate reference is then developed that explains the notion in terms of speakers' inclinations, while rejecting (...) the idea that this explanation should take the form of a reduction. The view is presented as a vindication of extreme nominalism, as it explains predicate reference solely in terms of the notion of qualia introduced by C.I. Lewis and developed by Nelson Goodman, which, it is argued, is definable in terms of speakers' classificatory propensities. Some connections are explored between the position that is presented and the views of Michael Dummett, John McDowell, Mark Johnston and Hilary Putnam, among others. (shrink)

In this paper I assess the two central ingredients of Laurence BonJour’s position on empirical knowledge that have survived the transition from his earlier coherentist views to his current endorsement of the doctrine of the given: his construal of the problem of the epistemic regress and his rejection of an internalist solution to the problem. The bulk of the paper is devoted to a critical assessment of BonJour’s arguments against externalism. I argue that they fail to put real pressure on (...) externalism, as they rely on a highly questionable conception of epistemic rationality and responsibility. Then, more briefly, I take issue with BonJour’s endorsement of the irrelevance thesis—the claim that even if externalism were true it would not offer a satisfactory solution to the epistemic regress problem. I contend that he is not entitled to subscribe this thesis unless he is prepared to abandon his construal of the problem. (shrink)

Corporate America is institutionalizing ethics through a variety of structures, systems, and processes. This study sought to identify managerial perceptions regarding the institutionalization of ethics in organizations. Eighty-six corporate level marketing and human resource managers of American multi-national corporations responded to a mail survey regarding the various implicit and explicit ways by which corporations institutionalize ethics. The results revealed that managers found ethics to be good for the bottom line of the organizations, they did not perceive the need for additional (...) formalization of ethics, and that they perceived implicit forms of institutionalizing ethics (e.g., leadership, corporate culture, top management support) to be more effective than the explicit forms of institutionalizing ethics (e.g., ethics ombudspeople, ethics committees, ethics newsletters). Implications of the survey and future research directions conclude the paper. (shrink)

Normative systems have been advocated as an effective tool to regulate interaction in multi-agent systems. The use of deontic operators and the ability to represent defeasible information are known to be two fundamental ingredients to represent and reason about normative systems. In this paper, after introducing a framework that combines standard deontic logic and non-monotonic logic programming, deontic logic programs (DLP), we tackle the fundamental problem of equivalence between normative systems using a deontic extension of David Pearce’s Equilibrium Logic and (...) its monotonic basis, the logic of Here-and-There. We also show how deontic logic programs can be used to represent and reason about normative systems, and establish a strong connection with input-output logic. (shrink)

Social sustainability is in its early stages in hospitality and tourism supply chains, especially in developing countries. This research draws on institutional and stakeholder theories to identify the adopted social sustainability practices in Egypt and to determine the factors affecting their implementation. A mixed-method research approach is followed involving interviews of hotel managers and a literature-based questionnaire answered by a total of 187 practitioners from hospitality and tourism supply chains in Egypt. The interviews revealed that social sustainability practices in the (...) two hotels' supply chains are adopted but limited to legal requirements and brand policies. Statistical analysis indicated that local suppliers boost the adoption of social practices. All the studied barriers show very weak correlation with the adoption of social sustainability practices; according to the interviews, this does not imply barriers inexistence, but rather reflects lack of awareness regarding social rights in a culture that tend to preserve social conservatism. The enablers explained significant variations in many social sustainability practices (53 out of 62). This study is unique since it offers a novel approach by linking institutional and stakeholder theories to recognize weaknesses in tourism supply chain social sustainability, thereby providing directions for the future design of sustainable tourism policies.

This article studies the differences between traditional financial intermediaries (commercial banks, savings banks and cooperative banks) and ethical banks based on property rights, in which the owner decides the ideology, principles, standards and objectives of the organisation. In ethical banking, affinity centres on positive social and ethical values. The article consequendy focuses on an index proposed both to differentiate ethical banks from other types of banks, and also to pinpoint the differences between the various ethical banks themselves.This is the Radical (...) Affinity Index (RAI), which groups banks together in terms of their stance on ethical commitment, concentrating on ethical ideology and principles (information transparency, placement of assets, guarantees and participation) and using a sample of 114 European banks. The evidence shows that transparency of information and placement of assets are factors that differentiate ethical banks from other financial intermediaries.Guarantees and participation are characteristics specific to ethical banks; these variables, however, do not offer clear evidence to our analysis.
