Alternative food networks, such as farmers’ markets and community-supported agricultural and fishery programs, often struggle to reach beyond a consumer base that is predominantly white and affluent. This case study explores seven inclusion strategies deployed by a community-supported fishery program (Fishadelphia, in Philadelphia, PA, USA) including discounting prices, accepting payment in multiple forms and schedules, offering a range of product types, communicating and recruiting through a variety of media (especially in person), and choosing local institutions and people of color (POC) (...) as pickup location hosts. Our analysis indicated that all of these strategies were associated with increased participation of customers of color and/or customers without a college degree. For Asian customers, accepting cash, offering whole fish, recruiting in-person, and POC-hosted pickup locations were key factors. For Black customers, discounted price, accepting cash, offering fillets, and communicating through means other than email were most important. Discounted price and communicating through means other than email were most important for customers without a college degree. Payment method, payment schedule and communication method were highly correlated with other strategies; we suggest that these strategies work in synergy to make the program attractive and feasible to these customers. We consider how Fishadelphia’s inclusion efforts have benefitted from both tactical approaches (i.e., programmatic features) and a structural approaches (i.e., the people and places represented within the project), and suggest that elements of both tactical and structural inclusion can be applied in other contexts. This work is crucial for increasing food access, and underscores the importance of relationships in recruiting diverse customers. (shrink)

1. L'Être et le néant. Critique de la raison dialectique.

Après avoir rappelé ce qu’est la version informatique du trans-humanisme et ses liens à la Singularité technologique, nous développons ici une réflexion sur le futur de l’Humanité, de l’humanisme et des humanités dans le contexte du développement rapide des technologies de l’information. La première partie rappelle les nombreuses annonces publiques qui prédisent une prochaine fin de l’Humanité. Nous analysons ensuite ce que signifie la fin de l’Humanité en distinguant d’abord la fin de l’espèce humaine de la fin de l’existence humaine. (...) La troisième partie étudie la signification d’une fin de l’humanisme, l’humanisme étant compris ici comme une philosophie qui considère que l’être humain est la valeur suprême. La dernière partie traite de la fin des humanités et conclut sur l’émergence d’un humanisme numérique qui donne un nouvel élan aux humanités. (shrink)

Today, with the digitisation of texts, sounds and images and their circulation on the Internet, we are deploying new techniques for storing knowledge which will increasingly supplement and even replace older memory recording systems, such as books, vinyl discs, and photographs on celluloid. It looks as if the extent of these changes will be far reaching. And if, as many believe, the practical methods of inscribing thought have an impact on the way it is developed through the writing and reading (...) process, we can understand why the changes now taking place could profoundly affect our ways of thinking. Here we have gathered together specialists in ancient means of recording memory - clay tablets, papyrus rolls and manuscripts - along with experts from the electronic age - originators of man-machine interfaces, enterprise knowledge management systems, hypermedia and intelligent agents - with the purpose of elucidating the present by reference to intellectual technologies of the past.

Hypertext encompasses a particular aspect of the virtual book that is playing an increasingly important part with the expansion of the Internet and the web. The success of HTML (HyperText Markup Language) - attests to its dynamism. Nowadays it seems so natural and so usual that we manipulate it with ease and we discover its ancestors among medieval cabalists or among other commentators of sacred texts. Every indexation, every note and every comment suggests a potential rudimentary hypertext. However, before its (...) expansion over the entire planet, with the network of worldwide telecommunication, before being programmed on to every PC, hypertext took form in the minds of a few learned visionaries. We will refer to two of them. (shrink)

There has been considerable discussion in the past about the assumptions and basis of different ethical rules. For instance, it is commonplace to say that ethical rules are defaults rules, which means that they tolerate exceptions. Some authors argue that morality can only be grounded in particular cases while others defend the existence of general principles related to ethical rules. Our purpose here is not to justify either position, but to try to model general ethical rules with artificial intelligence formalisms (...) and to compute logical consequences of different ethical theories. More precisely, this is an attempt to show that progress in non-monotonic logics, which simulates default reasoning, could provide a way to formalize different ethical conceptions. From a technical point of view, the model developed in this paper makes use of the Answer Set Programming (ASP) formalism. It is applied comparatively to different ethical systems with respect to their attitude towards lying. The advantages of such formalization are two-fold: firstly, to clarify ideas and assumptions, and, secondly, to use solvers to derive consequences of different ethical conceptions automatically, which can help in a rigorous comparison of ethical theories.

L’idée la plus répandue est que dans les années 40 Hayek délaissa l’économie en général et la théorie du cycle des affaires en particulier. En fait, Hayek est demeuré fidèle à ses idées sur ce dernier point. Sa théorie du cycle économique diffère de celle de Mises : Hayek a mis l’accent sur les perturbations endogènes qui donnent naissance aux cycles. Selon Hayek et Wicksell, le système bancaire ne parvient pas à arrêter cette expansion illusoire. Les derniers travaux de Hayek (...) sur la concurrence et la monnaie sont dans la lignée de son objectif de stabilisation monétaire. Il ne propose pas une théorie du cycle des affaires mais plutôt une théorie à propos de l’absence de cycles, une théorie de l’anti-cycle.The most commonly held idea is that in the 1940s Hayek lost interest in economics in general and in trade cycle theory in particular. Hayek did not change his mind on this subject. His trade cycle theory differs from Mises’one: Hayek puts the stress on the endogenous disturbance at the beginning of the trade cycle. According to both Hayek and Wicksell, the banking system fails to stop the false expansion. His late works on competition and money remain in line with his objective of monetary stabilization. Hayek does not present a trade cycle theory but rather a theory about the absence of a cycle, an anticycle theory. (shrink)

Artificial intelligence has often been seen as an attempt to reduce the natural mind to informational processes and, consequently, to naturalize philosophy. The many criticisms that were addressed to the so-called “old-fashioned AI” do not concern this attempt itself, but the methods it used, especially the reduction of the mind to a symbolic level of abstraction, which has often appeared to be inadequate to capture the richness of our mental activity. As a consequence, there were many efforts to evacuate the (...) semantical models in favor of elementary physiological mechanisms simulated by information processes. However, these views, and the subsequent criticisms against artificial intelligence that they contain, miss the very nature of artificial intelligence, which is not reducible to a “science of the nature”, but which directly impacts our culture. More precisely, they lead to evacuate the role of the semantic information. In other words, they tend to throw the baby out with the bath-water. This paper tries to revisit the epistemology of artificial intelligence in the light of the opposition between the “sciences of nature” and the “sciences of culture”, which has been introduced by German neo-Kantian philosophers. It then shows how this epistemological view opens on the many contemporary applications of artificial intelligence that have already transformed—and will continue to transform—all our cultural activities and our world. Lastly, it places those perspectives in the context of the philosophy of information and more particularly it emphasizes the role played by the notions of context and level of abstraction in artificial intelligence.

25 years ago, a department of Human relations training was created in a new school of engineers. We will see the history of this department, how it was perceived by professors and students, the oppositions, and the pedagogy we have implemented, particularly with project management.

Corruption is a serious problem in Mexico and the available information regarding the levels of academic dishonesty in Mexico is not very encouraging. Academic integrity is essential in any teaching-learning process focussed on achieving the highest standards of excellence and learning. Promoting and experiencing academic integrity within the university context has a twofold purpose: to achieve the necessary learnings and skills to appropriately perform a specific profession and to develop an ethical perspective which leads to correct decision making. The objective (...) of this study is to explore the relationship between academic integrity and ethical behaviour, particularly workplace behaviour. The study adopts a quantitative, hypothetical and deductive approach. A questionnaire was applied to 1203 college students to gather information regarding the frequency in which they undertake acts of dishonesty in different environments and in regards to the severity they assign to each type of infraction. The results reflect that students who report committing acts against academic integrity also report being involved in dishonest activities in other contexts, and that students who consider academic breaches less serious, report being engaged in academic misconduct more frequently in different contexts. In view of these results, it is unavoidable to reflect on the role that educational institutions and businesses can adopt in the development of programmes to promote a culture of academic integrity which: design educational experiences to foster learning, better prepare students to fully meet their academic obligations, highlight the benefits of doing so, prevent the severity and consequences of dishonest actions, discourage cheating and establish clear and efficient processes to sanction those students who are found responsible for academic breaches.

Ranking theory is one of the salient formal representations of doxastic states. It differs from others in being able to represent belief in a proposition (= taking it to be true), to also represent degrees of belief (i.e. beliefs as more or less firm), and thus to generally account for the dynamics of these beliefs. It does so on the basis of fundamental and compelling rationality postulates and is hence one way of explicating the rational structure of doxastic states. Thereby (...) it provides foundations for accounts of defeasible or nonmonotonic reasoning. It has widespread applications in philosophy, it proves to be most useful in Artificial Intelligence, and it has started to find applications as a model of reasoning in psychology. (shrink)

There are several approaches implementing reasoning based on conditional knowledge bases, one of the most popular being System Z (Pearl, Proceedings of the 3rd conference on theoretical aspects of reasoning about knowledge, TARK ’90, Morgan Kaufmann Publishers Inc., San Francisco, CA, USA, pp. 121–135, 1990). We look at ranking functions (Spohn, The Laws of Belief: Ranking Theory and Its Philosophical Applications, Oxford University Press, Oxford, 2012) in general, conditional structures and c-representations (Kern-Isberner, Conditionals in Nonmonotonic Reasoning and Belief Revision: (...) Considering Conditionals as Agents, vol. 2087 of LNCS, Springer, Berlin, 2001) in order to examine the reasoning strength of the different approaches by learning which of the known calculi of nonmonotonic reasoning (System P and R) and Direct Inference are applicable to these inference relations. Furthermore we use the recently proposed Enforcement-postulate (Kern-Isberner and Krümpelmann, Proceedings of the 22nd international joint conference on artificial intelligence, vol. 2, IJCAI’11, AAAI Press, pp. 937–942, 2011) to show dependencies between these approaches.

The idea of preserving conditional beliefs emerged recently as a new paradigm apt to guide the revision of epistemic states. Conditionals are substantially different from propositional beliefs and need specific treatment. In this paper, we present a new approach to conditionals, capturing particularly well their dynamic part as revision policies. We thoroughly axiomatize a principle of conditional preservation as an indifference property with respect to conditional structures of worlds. This principle is developed in a semi-quantitative setting, so as to reveal (...) its fundamental meaning for belief revision in quantitative as well as in qualitative frameworks. In fact, it is shown to cover other proposed approaches to conditional preservation. (shrink)

This special issue “Inferences and Information Processing in a Conditional Framework“ is dedicated to conditionals as central objects for inferencing and information processing. It presents selected revised papers of the Workshop on Conditionals, Information, and Inference, CII'04, held in Ulm, Germany, co-located with the German national conference on AI, KI'2004.Conditional statements If A then B carry a very special kind of information that can not be captured by interpreting them as material implications. Roughly speaking, the premise, A, provides a context (...) in which it seems plausible to conclude B. So, each conditional can be seen as establishing a tight but flexible link between premise and conclusion, making up a unique piece of information. This link can and has been used successfully for knowledge representation, in particular, for nonclassical inferences and revising beliefs.It is just this generic, dynamic nature of conditionals that makes them most fascinating objects which are, however, difficult to control. But it seems that the problems one typically encounters when using conditionals for reasoning, mostly occur due to the narrowness of thinking strictly along classical lines that we have been getting used to. Classical logic has imposed a rigidity on human thinking that helped a lot making reasoning formal, precise, and clear. Conditionals, on the other hand, open up dimensions beyond classical theories, leaving room for plausibility, uncertainty, intuition, and commonsense reasoning. Philosophers and logicians have been discussing their logical nature since the …. (shrink)

This book covers lymphoproliferative disorders in patients with congenital or acquired immunodeficiencies. Acquired immunodeficiencies are caused by infections with the human immunodeficiency virus or arise following immunosuppressive therapy administered after organ transplantation or to treat connective tissue diseases such as rheumatoid arthritis. It was recently discovered that various diseases or therapeutic modalities that induce a state of immunosuppression may cause virally driven lymphoproliferations. This book summarizes for the first time this group of immunodeficiency-associated lymphoproliferations.

Dans ce livre très original, Markus Gabriel avance une théorie du soi humain qui surmonte les blocages inhérents aux positions standards en philosophie de l’esprit contemporaine. Son point de vue, le néo-existentialisme, est intégralement antinaturaliste, en ce sens qu’il rejette toute théorie selon laquelle l’ensemble de nos meilleures connaissances scientifiques naturelles serait pleinement capable de rendre compte de l’esprit humain. L’auteur montre plutôt que l’esprit humain consiste en une prolifération ouverte de vocabulaires mentalistes. Leur rôle dans la forme de (...) vie humaine consiste à rendre compte du fait que l’être humain ne se fond pas simplement dans la nature inanimée et le reste du règne animal. Les humains s’appuient sur un autoportrait qui les situe dans un contexte aussi large que possible au sein de l’univers. Ce qui distingue cet autoportrait de notre connaissance de la réalité naturelle, c’est que nous changeons en vertu de nos croyances, vraies ou fausses, au sujet de nous-mêmes. (shrink)

We present different constructions for nonprioritized belief revision, that is, belief changes in which the input sentences are not always accepted. First, we present the concept of explanation in a deductive way. Second, we define multiple revision operators with respect to sets of sentences (representing explanations), giving representation theorems. Finally, we relate the formulated operators with argumentative systems and default reasoning frameworks.

Conditionals are most important objects in knowledge representation, commonsense reasoning and belief revision. Due to their non-classical nature, however, they are not easily dealt with. This paper presents a new approach to conditionals, which is apt to capture their dynamic power particularly well. We show how this approach can be applied to represent conditional knowledge inductively, and to guide revisions of epistemic states by sets of beliefs. In particular, we generalize system-Z* as an appropriate counterpart to maximum entropy-representations in a (...) semi-quantitative setting, and provide a theoretical justification to make its basic ideas usable also for belief revision.

In this article we explore multiple change operators, i.e., operators in which the epistemic input is a set of sentences instead of a single sentence. We propose two types of change: prioritized change, in which the input set is fully accepted, and symmetric change, where both the epistemic state and the epistemic input are equally treated. In both kinds of operators we propose a set of postulates and we present different constructions: kernel changes and partial meet changes.

This book presents contributions from an internal symposium organized to celebrate the 80th anniversary of the Specola Vaticana, or Vatican Observatory, in the Papal Palace of Castel Gandolfo. The aim is to provide an overview of the scientific and cultural work being undertaken at the Observatory today and to describe the outcomes of important recent investigations. The contents cover interesting topics in a variety of areas, including planetary science and instrumentation, stellar evolution and stars, galaxies, cosmology, quantum gravity, the history (...) of astronomy, and interactions between science, philosophy, and theology. On September 29, 1935, Pope Pius XI officially inaugurated the new headquarters of the Specola Vaticana at Castel Gandolfo. With new telescopes, a new astrophysical laboratory for spectrochemical analysis, and a young staff comprising Jesuit scientists, this inauguration marked the beginning of an intense period of scientific achievements at the Observatory. This anniversary book, featuring contributions from members of the current Observatory staff and adjunct scholars, will appeal to all with an interest in the history of the Specola Vaticana and its significance for astronomy.

We study the behavior of the game operator $$ on Wadge classes of Borel sets. In particular we prove that the classical Moschovakis results still hold in this setting. We also characterize Wadge classes ${\bf{\Gamma }}$ for which the class has the substitution property. An effective variation of these results shows that for all $1 \le \eta < \omega _1^{{\rm{CK}}}$ and $2 \le \xi < \omega _1^{{\rm{CK}}}$, is a Spector class while is not.
