Solidarity as a social phenomenon means a sharing of feelings, interests, risks and responsibilities. The Western-European Welfare State can be seen as an organized system of solidarity, historically grown from group solidarity among workers, later between workers and employers, moving towards solidarity between larger social groups: between healthy people and the sick, between the young and the elderly, between the employed and the unemployed. This sharing of risks at a societal level however, has revealed the risks of sharing. In the (...) postwar development of the welfare state, solidarity has been organized mainly in administrative forms, run by anonymous bureaucracies and giving way to free riders and calculative citizens. This article describes this development and provides arguments for a reorientation of the welfare state and for the re-allocation of rights, risks and responsibilities. (shrink)

One of the new ways used by companies to demonstrate their social responsibility is to encourage employee volunteering, whereby employees engage in socially beneficial activities on company time, while being paid by the company. The reasoning is that it is good for employee motivation (internal effects) and good for the company reputation (external effects). This article reports an empirical investigation of the internal effects of employee volunteering conducted amongst employees of the Dutch ABN-AMRO bank. The study showed that (a) socio-demographic (...) characteristics from employee volunteers markedly differ from those of non-volunteers and community volunteers and (b) employee volunteering seems to have positive effects on attitudes and behavior towards the organization.

Demonstrative noun phrases (e.g. this; that guy over there ) are intimately connected to the context of use in that their reference is determined by demonstrations and/or the speaker's intentions. The semantics of demonstratives therefore has important implications not only for theories of reference, but for questions about how information from the context interacts with formal semantics. First treated by Kaplan as directly referential , demonstratives have recently been analyzed as quantifiers by King, and the choice between these two approaches (...) is a matter of ongoing controversy. Meanwhile, linguists and psychologists working from a variety of perspectives have gathered a wealth of data on the form, meaning, and use of demonstratives in many languages. Demonstratives thus provide a fruitful topic for graduate study for two reasons. On the one hand, they serve as an entry point to foundational issues in reference and the semantics–pragmatics interface. On the other hand, they are an especially promising starting point for interdisciplinary research, which brings the results of linguistics and related fields to bear on the philosophy of language.

A substantial amount of recent work in natural language generation has focused on the generation of ‘‘one-shot’’ referring expressions whose only aim is to identify a target referent. Dale and Reiter's Incremental Algorithm (IA) is often thought to be the best algorithm for maximizing the similarity to referring expressions produced by people. We test this hypothesis by eliciting referring expressions from human subjects and computing the similarity between the expressions elicited and the ones generated by algorithms. It turns out that (...) the success of the IA depends substantially on the ‘‘preference order’’ (PO) employed by the IA, particularly in complex domains. While some POs cause the IA to produce referring expressions that are very similar to expressions produced by human subjects, others cause the IA to perform worse than its main competitors; moreover, it turns out to be difficult to predict the success of a PO on the basis of existing psycholinguistic findings or frequencies in corpora. We also examine the computational complexity of the algorithms in question and argue that there are no compelling reasons for preferring the IA over some of its main competitors on these grounds. We conclude that future research on the generation of referring expressions should explore alternatives to the IA, focusing on algorithms, inspired by the Greedy Algorithm, which do not work with a fixed PO.

This article introduces the topic ‘‘Production of Referring Expressions: Bridging the Gap between Computational and Empirical Approaches to Reference’’ of the journal Topics in Cognitive Science. We argue that computational and psycholinguistic approaches to reference production can benefit from closer interaction, and that this is likely to result in the construction of algorithms that differ markedly from the ones currently known in the computational literature. We focus particularly on determinism, the feature of existing algorithms that is perhaps most clearly at (...) odds with psycholinguistic results, discussing how future algorithms might include non-determinism, and how new psycholinguistic experiments could inform the development of such algorithms.

This paper asks why information should ever be expressed vaguely, re-assessing some previously proposed answers to this question and suggesting some new ones. Particular attention is paid to the benefits that vague expressions can have in situations where agreement over the meaning of an expression cannot be taken for granted. A distinction between two different versions of the above-mentioned question is advocated. The first asks why human languages contain vague expressions, the second question asks when and why a speaker should (...) choose a vague expression when communicating with a hearer. While the former question is purely theoretical, the latter has practical implications for the computational generation of utterances in Natural Language Generation (NLG). (shrink)

Two questions dominate theoretical research on vagueness. The first is of a logical-semantic nature: What formal models offer the best understanding of vagueness? Many answers to this question have been proposed (e.g. [1], [2] for an overview), but none of these has found general acceptance so far. The second question is of a pragmatic nature and asks Why is language vague? This question has been asked forcefully by the economist Barton Lipman, who has shown that some seemingly plausible answers resist (...) analysis in terms of classical Game Theory [3], [4]. While a number of tentative answers to this question have been suggested (for a survey, see [6], [7]), Lipman’s question is still partly unresolved, particularly with respect to situations where there is no conflict between the speaker and the hearer (cf. [8]). (shrink)

This article explores the role of surface ambiguities in referring expressions, and how the risk of such ambiguities should be taken into account by an algorithm that generates referring expressions, if these expressions are to be optimally effective for a hearer. We focus on the ambiguities that arise when adjectives occur in coordinated structures. The central idea is to use statistical information about lexical co-occurrence to estimate which interpretation of a phrase is most likely for human readers, and to avoid (...) generating phrases where misunderstandings are likely. Various aspects of the problem were explored in three experiments in which responses by human participants provided evidence about which reading was most likely for certain phrases, which phrases were deemed most suitable for particular referents, and the speed at which various phrases were read. We found a preference for ‘‘clear’’ expressions to ‘‘unclear’’ ones, but if several of the expressions are ‘‘clear,’’ then brief expressions are preferred over non-brief ones even though the brief ones are syntactically ambiguous and the non-brief ones are not; the notion of clarity was made precise using Kilgarriff's Word Sketches. We outline an implemented algorithm that generates noun phrases conforming to our hypotheses. (shrink)

This informal position paper brings together some recent developments in formal semantics and pragmatics to argue that the discipline of Game Theory is well placed to become the theoretical backbone of Natural Language Generation. To demonstrate some of the strengths and weaknesses of the Game-Theoretical approach, we focus on the utility of vague expressions. More specifically, we ask what light Game Theory can shed on the question when an NLG system should generate vague language.

This paper supplies a structuralist reconstruction of the Modigliani-Miller theory and shows that the economic literature following their results reports on research with an implicit strategy to come "closer-to-the-truth" in the modern technical sense in philosophy of science.

This article offers a survey of computational research on referring expressions generation (REG). It introduces the REG problem and describes early work in this area, discussing what basic assumptions lie behind it, and showing how its remit has widened in recent years. We discuss computational frameworks underlying REG, and demonstrate a recent trend that seeks to link up REG algorithms with well-established Knowledge Representation traditions. Considerable attention is given to recent efforts at evaluating REG algorithms and the lessons that they (...) allow us to learn. The article concludes with a discussion of the way forward in REG, focussing on references in larger and more realistic settings. (shrink)

In this paper we defend a rather traditional view of pronouns that is based on the fundamental opposition between reference and anaphora: local pronouns are referential, like names and other indexicals, while third person proouns are anaphoric. We argue against the grammatical classification based on the opposition between pronouns and R-expressions: all pronouns, but not names and other indexicals, are systematically ambiguous between a bound-variable and a referential reading. More specifically we aim to defuse Kratzer's recent argumentation aimed at establishing (...) that local pronouns indeed allow both referential and bound interpretations. We then present an alternative pragmasemantic analysis of Kratzer's and our own data that is fully in line with the traditional analysis of local pronouns and other indexicals as purely referential expressions.

The development of an ethics program is a method frequently used for organising responsible behaviour within organisations. For such a program, certain preconditions have to be created in the structure, culture and strategy. In this organisational context, managers have to take their decisions in a responsible way. This process of decision-making, embedded in an ethics program, is the main focus of this article. Ethics programs often influence decision-making in a formal way; certain norms and types of behaviour are formalised and (...) controlled within the organisation. Subsequently, individual managers have to infer the meaning of responsible behaviour from the demands laid down in the ethics program. Such a formal ethics program has some important advantages but the dangers of such an approach are often ignored. This article discusses both the advantages and disadvantages of a formal ethics program and adds two alternative ways of stimulating responsible behaviour in the organisation. In a monological approach the reflections of the decision makers on their own values are central in differentiating between right and wrong. In a dialogical approach, the communications between decision makers and other stakeholders involved are the foundations for determining a responsible solution. Because each approach is appropriate for certain issues, a well-chosen combination is justified. Such an ethics program should be strict on certain issues but leave room for reflection and interaction on other issues. (shrink)

A fundamental part of the process of referring to an entity is to categorise it (for instance, as the woman). Where multiple categorisations exist, this implicitly involves the adoption of a conceptual perspective. A challenge for the automatic Generation of Referring Expressions is to identify a set of referents coherently, adopting the same conceptual perspective. We describe and evaluate an algorithm to achieve this. The design of the algorithm is motivated by the results of psycholinguistic experiments.

This discussion paper describes a sequence of experiments with human subjects aimed at finding out how an nlg system should choose between the different forms of a gradable adjective. This case study highlights some general questions that one faces when trying to base nlg systems on empirical evidence: one question is what task to set a subject so as to obtain the most useful information about that subject, another question has to do with differences between subjects.

Media in Question sets the agenda for a revitalized debate on the hybrid communicative practices that constitute the postmodern media landscape: practices that cross the boundaries between fact and fiction, information and entertainment, public knowledge, and popular culture. In this challenging and provocative collection, the individual contributors rethink key issuesùthe meaning of the public interest, the quality of media performance, and deregulation. In the process they raise questions rarely addressed in normative media theories, for example, the ethics of sports reporting, (...) the moral reasoning in popular culture, and the required professional standards for infotainment genres such as reality television and gossip journalism. Accessible and wide-ranging, The Media in Question will be essential reading for students in mass communication and political communication studies. (shrink)

This paper outlines a multi-agent architecture for regulated information exchange of crime investigation data between police forces. Interactions between police officers about information exchange are analysed as negotiation dialogues with embedded persuasion dialogues. An architecture is then proposed consisting of two agents, a requesting agent and a responding agent, and a communication language and protocol with which these agents can interact to promote optimal information exchange while respecting the law. Finally, dialogue policies are defined for the individual agents, specifying their (...) behaviour within a negotiation. Essentially, when deciding to accept or reject an offer or to make a counteroffer, an agent first determines whether it is obligatory or permitted to perform the actions specified in the offer. If permitted but not obligatory, the agent next determines whether it is in his interest to accept the offer. (shrink)

Abstract This essay argues that one way of understanding Gramsci today is as an organic intellectual of a class of managerial cadre which develops in advanced capitalism. With the growth of monopolistic structures and a deepening state role in capitalist society, a separate class of mediating functionaries emerges, entrusted with managerial tasks in running the economy and the state. The problems of conquering power from the perspective of this ?new middle class? that concerned Gramsci, were also those of the neo?Machiavellian (...) thinkers, Mosca, Michels, Pareto and Sorel around the turn of the twentieth century. From opposed political angles, they and Gramsci shared the concern with occupying the centre ground and mediate the extremes in a complex society. Today?s Gramscianism appeals to the same set of concerns. (shrink)

This response discusses the experiment reported in Krahmer et al.’s Letter to the Editor of Cognitive Science. We observe that their results do not tell us whether the Incremental Algorithm is better or worse than its competitors, and we speculate about implications for reference in complex domains, and for learning from ‘‘normal” (i.e., non-semantically-balanced) corpora.

In twentieth-century Kant scholarship, few have provided an account of the analytic-synthetic distinction and of the problem of the synthetic a priori that takes into consideration the views of Kant's idealist successors such as Maimon, Fichte, Schelling, and Hegel. I first explain how Kant formulates the analytic-synthetic distinction in terms of the determinate-indeterminate distinction, which, in turn, is based on the distinction between general and transcendental logic. Kant's problem of the synthetic a priori , then, is the problem of showing (...) how the logical forms of judgment can be employed determinately (and not merely indeterminately). I then show that Maimon also formulates the distinction and the problem in the same way, and that his interpretation will shape how Fichte, Schelling, and Hegel each construe and address Kant's question, How are synthetic judgments possible a priori ?

Kant’s analytic-synthetic distinction is often construed in terms of the question of whether or not the predicate is contained in or can be derived from the concept of the subject. Few have observed that Kant has another formulation of the distinction, a formulation that is based on the determinate-indeterminate distinction. In fact, it is this formulation that will shape the development of one of the main tasks of post-Kantian German idealism. It is my aim to explain how Kant, Maimon, and (...) Fichte each define and address the problem of the synthetic a priori in terms of the determinate-indeterminate distinction. (shrink)
