By considering what we identify as a problem inherent in the ‘nature of the firm’—the risk of abuse of authority—we propound the conception of a social contract theory of the firm which is truly Rawlsian in its inspiration. Hence, we link the social contract theory of the firm with the general theory of justice. Through this path, we enter the debate about whether firms can be part of Rawlsian theory of justice showing that corporate governance principles enter the “basic structure.” (...) Finally, we concur with Sen’s aim to broaden the realm of social justice beyond what he calls the ‘transcendental institutional perfectionism’ of Rawls’ theory. We maintain the contractarian approach to justice but introduce Sen’s capability concept as an element of the constitutional and post-constitutional contract model of institutions with special reference to corporate governance. Accordingly, rights over primary goods and capabilities are granted by the basic institutions of society, but many capabilities have to be turned into the functionings of many stakeholders through the operation of firms understood as post-constitutional institutional domains. The constitutional contract on the distribution of primary goods and capabilities should then shape the principles of corporate governance so that at post-constitutional level anyone may achieve her/his functionings in the corporate domain by exercising such capabilities. In the absence of such a condition, post-constitutional contracts would distort the process that descends from constitutional rights and capabilities toward social outcomes. (shrink)

Rips et al.'s arguments for rejecting basic number representations as a precursor of the natural number system are exclusively based on analog number coding. We argue that these arguments do not apply to place coding, a type of basic number representation that is not considered by Rips et al.

Comments on an article by Feigenson et. al.(see record 2004-18473-007). Reviewing behavioral and neural data in children, humans and animals, Feigenson and colleagues distinguish two core systems for number representation. One system represents number in an exact way but has a fixed upper limit; the other system has no size limit but represents number only approximately. Both systems are claimed to have a phylogenetic origin and to constitute the basis for ontogenetic development. As such, each system's representational principles are reflected (...) in adult human performance: subitizing is ascribed to the exact system whereas symbolic number processing is based on a mapping to the approximate system. This last assumption is motivated by the robust finding that symbolic numbers are more difficult to discriminate with increasing size (the 'size effect'). However, it remains to be shown how this mapping can reconcile the inherently exact nature of a symbolic system with signatures of approximate processing such as the size effect.

We challenge the arguments of Cohen Kadosh & Walsh (CK&W) on two grounds. First, interactions between number form (e.g., notation, format, modality) and an experimental factor do not show that the notations/formats/modalities are processed separately. Second, we discuss evidence that numbers are coded abstractly, also when not required by task demands and processed unintentionally, thus challenging the authors' dual-code account.

Recent years have witnessed an enormous increase in behavioral and neuroimaging studies of numerical cognition. Particular interest has been devoted toward unraveling properties of the representational medium on which numbers are thought to be represented. We have argued that a correct inference concerning these properties requires distinguishing between different input modalities and different decision/output structures. To back up this claim, we have trained computational models with either symbolic or nonsymbolic input and with different task requirements, and showed that this allowed (...) for an integration of the existing data in a consistent manner. In later studies, predictions from the models were derived and tested with behavioral and neuroimaging methods. Here we present an integrative review of this work. (shrink)

A central controversy in cognitive science concerns the roles of rules versus similarity. To gain some leverage on this problem, we propose that rule‐ versus similarity‐based processes can be characterized as extremes in a multidimensional space that is composed of at least two dimensions: the number of features (Pothos, 2005) and the physical presence of features. The transition of similarity‐ to rule‐based processing is conceptualized as a transition in this space. To illustrate this, we show how a neural network model (...) uses input features (and in this sense produces similarity‐based responses) when it has a low learning rate or in the early phases of training, but it switches to using self‐generated, more abstract features (and in this sense produces rule‐based responses) when it has a higher learning rate or is in the later phases of training. Relations with categorization and the psychology of learning are pointed out. (shrink)

I sin udmærkede kommentar til vores artikel «En etisk diskussion af screening for kræftsygdomme» beskriver Geir Hoff den udtalte mangel på evidens vedrørende nytteværdien af screeningsprogrammer for kræftsygdomme baseret på randomiserede studier. Ydermere fremhæver Geir Hoff misforholdet mellem den manglende evidens ved screening og de strenge krav, der er til evidensen i den farmaceutiske industri. Dette er en velkommen kritik, pga. en udtalt ukritisk og uvidenskabelig tilgang til anvendelse af screening for denne eller hin sygdom eller risikofaktor.

I 2007 gennemførte forbundskansler Angela Merkel en sundhedsreform der blandt andet indebærer, at tyske borgere ikke frit kan afgøre, om de vil deltage i forebyggende programmer, da et fravalg kan medføre økonomiske konsekvenser. Hermed udvider den tyske stat sin ret til at gribe ind i borgernes liv, når det handler om sekundær forebyggelse, fx i form af screening for kræftsygdomme. Dette kan være problematisk da den bedst tilgængelige evidens viser at tre igangværende kræftscreeningsprogrammer ikke kun har gavnlige virkninger, men også (...) betydelige skadelige virkninger. Formålet med denne undersøgelse var at undersøge, hvilke holdninger eksperter, politikere og sundhedsmyndigheder i Danmark har til tvang og/eller belønning i forbindelse med screening for kræftsygdomme, og om de ville støtte eller fraråde en tysk model i det danske sundhedsvæsen.Der blev foretaget enkeltinterviews med strategisk udvalgte eksperter. Interviewene blev transskriberet og analyseret med en fænomenologisk analysemetode, og derefter analyseret og diskuteret i forhold til utilitaristisk og deontologisk etik, samt evidensen vedrørende de tre eksisterende kræftscreeningsprogrammer i Danmark.Alle informanterne var kritiske over for det tyske forslag. Til gengæld blev forholdet mellem de gavnlige og skadelige virkninger af kræftscreening vurderet meget forskelligt. Manglen på enighed, uklare udtalelser og ikke-stringent terminologi bestyrkede vor konklusion; at det danske sundhedsvæsen for det første ikke bør følge den tyske kurs og, for det andet, at man bør være kritisk over for implementering af screeningsprogrammer for kræftsygdomme. Hvis forebyggende initiativer kan være mere til skade end gavn, bør de altid overvejes nøje i lyset af sundhedsvæsnets oprindelige intention om at hjælpe og beskytte det enkelte menneske. (shrink)

The mental representation of brief temporal durations, when assessed in standard laboratory conditions, is highly accurate. Here we show that adding or subtracting temporal durations systematically results in strong and opposite biases, namely over-estimation for addition and under-estimation for subtraction. The difference with respect to a baseline temporal reproduction task changed across durations in an operation-specific way and survived correcting for the effect due to operation sign alone, indexing a reliable signature of arithmetic processing on time representation. A second experiment (...) replicated these findings with a different set of stimuli. This novel behavioral marker conceptually mirrors in the time domain the representational momentum found with motion, whereby the estimated spatial position of a visual target is displaced in the direction of motion itself. This momentum effect in temporal arithmetic suggests a striking analogy between time processing and visuospatial processing, which might index the presence of common computational principles.

The subjective feeling of free choice is an important feature of human experience. Experimental tasks have typically studied free choice by contrasting free and instructed selection of response alternatives. These tasks have been criticised, and it remains unclear how they relate to the subjective feeling of freely choosing. We replicated previous findings of the fMRI correlates of free choice, defined objectively. We introduced a novel task in which participants could experience and report a graded sense of free choice. BOLD responses (...) for conditions subjectively experienced as free identified a postcentral area distinct from the areas typically considered to be involved in free action. Thus, the brain correlates of subjective feeling of free action were not directly related to any established brain correlates of objectively-defined free action. Our results call into question traditional assumptions about the relation between subjective experience of choosing and activity in the brain’s so-called voluntary motor areas. (shrink)

Még 2013 májusában került sor arra a Metafora című nyelvészeti és filozófiai workshopra, amelynek a keretein belül elhangzottak a jelen kötetben helyet kapott tanulmányok alapját képező, az Erasmus Kollégium nyelvfilozófiai kutatócsoportjának tagjai által jegyzett előadások. Ezeknek, s így a mostani összeállításnak is kiemelt témája a relevanciaelmélet, amellyel (pontosabban annak metaforafelfogásával) részletesen foglalkozik a bevezető dolgozat, illetve az azt követő három írás. Ezek közül az elsőben Pete Krisztián a teória klasszikus vonulatát állítja párhuzamba az átdolgozott, továbbfejlesztett változatokkal, majd Zvolenszky Zsófia - (...) részben ehhez kapcsolódva - a konvencionális és költői metaforák témáját illetően kritikával illeti a modern megközelítést. Kuti Judit a Sperber-Wilson- és a Harald Weinrich-féle metaforaelméletet hasonlítja össze. A folytatásban olyanok metaforaleméleteivel ismerkedhetünk meg, mint Donald Davidson és Paul Ricoeur; Kálmán László egy hagyományos irányzatból kinövő, mégis új nyelvfelfogást és metaforaelemzést mutat be; Kiss Angelika és Jellinek Sára egy-egy nyelvhasználati jelenséget és metaforikus beszédmódot mutat be (a japán és koreai nyelv, és a humor nyelvfilozófiai vonatkozásai kapcsán); Nemesi Attila László a filmes és mozgóképes trópusokról, s azok csoportosításáról ír; Molnár Cecília Sarolta pedig a mai modern dalszövegek metaforakészletét elemzi. A mutatóval záruló kiadvány nyelvészeti szakgyűjteményekbe javasolható beszerzésre. (shrink)
