We analyse whether Belgian tax policy over the period 1965-1995 was affected by the ideological position of the government. Both the level and composition of taxation are considered. We find no significant ideological effect on the level of the tax burden. The burden has increased systematically over most of the period, irrespective of the ideology of the incumbent. Considering individual tax categories, one can find a significant ideological influence for taxes on financial and capital transactions. Under centre-left oriented governments this (...) tax is lowered whereas it increases under centre-right governments. A possible explanation is that centre-left governments try to stimulate households' wealth acquisition by keeping taxes on transactions of immovable properties low. (shrink)

Argumentation as the public exchange of reasons is widely thought to enhance deliberative interactions that generate and justify reasonable public policies. Adopting an argumentation-theoretic perspective, we survey the norms that should govern public argumentation and address some of the complexities that scholarly treatments have identified. Our focus is on norms associated with the ideals of correctness and participation as sources of a politically legitimate deliberative outcome. In principle, both ideals are mutually coherent. If the information needed for a correct deliberative (...) outcome is distributed among agents, then maximising participation increases information diversity. But both ideals can also be in tension. If participants lack competence or are prone to biases, a correct deliberative outcome requires limiting participation. The central question for public argumentation, therefore, is how to strike a balance between both ideals. Rather than advocating a preferred normative framework, our main purpose is to illustrate the complexity of this theme. (shrink)

Human cognition is unique in the way in which it relies on combinatorial (or compositional) structures. Language provides ample evidence for the existence of combinatorial structures, but they can also be found in visual cognition. To understand the neural basis of human cognition, it is therefore essential to understand how combinatorial structures can be instantiated in neural terms. In his recent book on the foundations of language, Jackendoff described four fundamental problems for a neural instantiation of combinatorial structures: the massiveness (...) of the binding problem, the problem of 2, the problem of variables, and the transformation of combinatorial structures from working memory to long-term memory. This paper aims to show that these problems can be solved by means of neural “blackboard” architectures. For this purpose, a neural blackboard architecture for sentence structure is presented. In this architecture, neural structures that encode for words are temporarily bound in a manner that preserves the structure of the sentence. It is shown that the architecture solves the four problems presented by Jackendoff. The ability of the architecture to instantiate sentence structures is illustrated with examples of sentence complexity observed in human language performance. Similarities exist between the architecture for sentence structure and blackboard architectures for combinatorial structures in visual cognition, derived from the structure of the visual cortex. These architectures are briefly discussed, together with an example of a combinatorial structure in which the blackboard architectures for language and vision are combined. In this way, the architecture for language is grounded in perception. Perspectives and potential developments of the architectures are discussed. Key Words: binding; blackboard architectures; combinatorial structure; compositionality; language; dynamic system; neurocognition; sentence complexity; sentence structure; working memory; variables; vision.

Deze studie wil de wijsgerig-ethische stromingen van de 19e en 20e eeuw op een overzichtelijke wijze presenteren. Zij biedt veel en ongetwijfeld kan zij dienst doen als een eerste oriëntatie. De continentale filosofie komt goed aan de orde, zij het dat de auteurs de aandacht voor de bibliografische notities vaak laten gaan ten koste van de toch al summiere inhoudelijke inleidingen. De auteurs beschrijven en beoordelen - dikwijls in moraliserende termen - maar gaan niet in dialoog noch met de behandelde (...) auteur noch met de lezer. De angelsaksische wereld komt nauwelijks aan de orde (29 blz.). De betekenis van de analytische ethiek voor de normatieve ethiek wordt niet gezien. Het boek stopt ook te vlug. De recente ontwikkelingen komen niet aan de orde. Over narratieve ethiek wordt niet gesproken. Maar evenmin over de hernieuwde aandacht voor de deugden-ethiek. Deze studie laat duidelijk zien dat de gigantische onderneming om een goede inleiding in de wijsbegeerte en de ethiek van de 19e en 20e eeuw te schrijven, niet door een of twee personen kan worden voltooid.

A central aim of Construction Grammar is to model links within the construct-i-con. This paper investigates three constructions that share one property: an atypical element in the object slot. The constructions are therefore not prototypically transitive. Structural priming (implemented with an automatic maze variant of self-paced reading) is used to test hypotheses on the relation among the Reaction Objoid (She smiled her thanks), the Cognate Objoid (She smiled a sweet smile or He told a sly tale), and the Superlative Objoid (...) (She smiled her sweetest) Construction, and between two variants of the latter (They worked (at) their hardest). Results support transitivity as gradient: intransitive COCs prime the ROC and the SOC, whereas COCs with transitives only prime the ROC. For variants of the SOC, we find evidence of asymmetric priming with the bare SOC priming the at-SOC. Within-construction priming effects in the SOC are of greater magnitude than those with the at-SOC and the latter are weaker than those of the COC and of a rather different nature than those from the ROC. This suggests that speakers, rather than creating a constructeme between the bare and the at-SOC, store distinct but closely related constructions on a cline of transitivity. (shrink)

Using the artificial language paradigm, we studied the acquisition of morphophonemic alternations with exceptions by 160 German adult learners. We tested the acquisition of two types of alternations in two regularity conditions while additionally varying length of training. In the first alternation, a vowel harmony, backness of the stem vowel determines backness of the suffix. This process is grounded in substance (phonetic motivation), and this universal phonetic factor bolsters learning a generalization. In the second alternation, tenseness of the stem vowel (...) determines backness of the suffix vowel. This process is not based in substance, but it reflects a phonotactic property of German and our participants benefit from this language-specific factor. We found that learners use both cues, while substantive bias surfaces mainly in the most unstable situation. We show that language-specific and universal factors interact in learning. (shrink)

Wilson et al. focus on one class of AGL tasks: the cognitively demanding task of detecting non‐adjacent dependencies (NADs) among items. They provide a typology of the different types of NADs in natural languages and in AGL tasks. A range of cues affect NAD learning, ranging from the variability and number of intervening elements to the presence of shared prosodic cues between the dependent items. These cues, important for humans to discover non‐adjacent dependencies, are also found to facilitate NAD learning (...) in several nonhuman animal species. (shrink)

Dans l'oeuvre d'Edith Stein, l'alterite apparait comme constitutive de la personne humaine. D'un point de vue proprement subjectif, l'alterite renvoie... l'alter ego,... la dimension communautaire et, dans une perspective croyante, au Tout-Autre. D'un point de vue objectif, elle designe les valeurs, qui faconnent la personnalite, et la foi, qui vient au secours de la raison humaine. Un parcours des oeuvres principales de l'auteur permet de prendre la mesure... la fois de la continuite et de l'evolution de sa pensee. A partir (...) de l..., l'etude entreprend de mettre en evidence, d'une part, l'originalite de la pensee d'Edith Stein par rapport... celle de Husserl et, d'autre part, comment Edith Stein se situe par rapport... la pensee de Thomas d'Aquin. L'influence de l'oeuvre de Jean de la Croix est egalement abordee. Enfin, en dialogue avec des auteurs comme Ricoeur, Levinas ou Ladriere, la troisieme partie du livre aborde de maniere critique la question de l'alterite comme fondement de la personne et cela selon trois parcours, l'un lie... la phenomenologie d'Edith Stein, l'autre... sa philosophie chretienne, et le dernier... son attrait pour la mystique.

The division of cognitive labor is fundamental to all cultures. Adults have a strong sense of how knowledge is clustered in the world around them and use that sense to access additional information, defer to relevant experts, and ground their own incomplete understandings. One prominent way of clustering knowledge is by disciplines similar to those that comprise the natural and social sciences. Seven studies explored an emerging sense of these discipline‐based ways of clustering of knowledge. Even 5‐year‐olds could cluster knowledge (...) in a manner roughly corresponding to the departments of natural and social sciences in a university, doing so without any explicit awareness of those academic disciplines. But this awareness is fragile early on and competes with other ways of clustering knowledge. Over the next few years, children come to see discipline‐based clusters as having a privileged status, one that may be linked to increasingly sophisticated assumptions about essences for natural kinds. Possible mechanisms for this developmental shift are examined. (shrink)

Social innovations are urgently needed as we confront complex social problems. As these social problems feature substantial interdependencies among multiple systems and actors, developing and implementing innovative solutions involve the re-negotiating of settled institutions or the building of new ones. In this introductory article, we introduce a stylized three-cycle model highlighting the institutional nature of social innovation efforts. The model conceptualizes social innovation processes as the product of agentic, relational, and situated dynamics in three interrelated cycles that operate at the (...) micro, meso, and macro levels of analysis. The five papers included in this special issue address one or more of these cycles. We draw on these papers and the model to stimulate and offer guidance to future conversations on social innovations from an institutional theory perspective. (shrink)

The paper is meant to be a contribution to the study of Indian and comparative ethics. It treats the Vajjālaggam, an anthology of Prākrit stanzas (subhāsita literature) dealing with a variety of topics. Focusing on the ‘ethical’ sections of the VL, it tries to describe and analyse its underlying ethical system. In Part I the different ethical themes of the VL (Valour and Destiny, Virtues and Vices, Masters and Servants, Friendship and Affection, Poverty and Charity) are described in detail. In (...) Part II it is shown that the VL. offers a clear example of a virtue ethic with a strong emphasis on self‐regarding virtues (gunas), based on a pluralistic and instrumental theory of the good. The paper also treats the crucial ethical problem of the relationship between personal well‐being and virtuousness as described in the VL. (shrink)

Knowledge representation, which lies at the core of artificial intelligence, is concerned with encoding knowledge on computers to enable systems to reason automatically. The aims are to help readers make their computer smarter, handle qualitative and uncertain information, and improve computational tractability.
