We show that it is independent whether club $\kappa $ -Miller forcing preserves $\kappa ^{++}$. We show that under $\kappa ^{ \kappa $, club $\kappa $ -Miller forcing collapses $\kappa ^{<\kappa }$ to $\kappa $. Answering a question by Brendle, Brooke-Taylor, Friedman and Montoya, we show that the iteration of ultrafilter $\kappa $ -Miller forcing does not have the Laver property.

Since the introduction of photography by commercial studio photographers and the colonial state in Kenya, this global medium has been intensely debated and contested among Muslims on the cosmopolitan East African coast. This book does not only explore the making, circulation, and consumption of popular photographs, but also the other side, their rejection and obliteration, an essential aspect of a medium's history that should not be neglected. It deals with various »social spaces of refusal« in the local Muslim milieu and (...) in that of »traditional« spirit mediums in which visibility was contested in various and creative ways. It focuses on the »aesthetics of withdrawal«: the various ways and techniques that process the photographic act as well as the photographic image to theatricalize the surface of the image in new ways by veiling, masking, and concealing. In a fragmented historical perspective, Heike Behrend seeks to complement, decenter, and counter the history of photography as it has been told by the West and to narrate another history beginning with preceding local media such as textiles and spirit possession.

In this article, we develop the concept of Transparency by Design that serves as practical guidance in helping promote the beneficial functions of transparency while mitigating its challenges in automated-decision making environments. With the rise of artificial intelligence and the ability of AI systems to make automated and self-learned decisions, a call for transparency of how such systems reach decisions has echoed within academic and policy circles. The term transparency, however, relates to multiple concepts, fulfills many functions, and holds different (...) promises that struggle to be realized in concrete applications. Indeed, the complexity of transparency for ADM shows tension between transparency as a normative ideal and its translation to practical application. To address this tension, we first conduct a review of transparency, analyzing its challenges and limitations concerning automated decision-making practices. We then look at the lessons learned from the development of Privacy by Design, as a basis for developing the Transparency by Design principles. Finally, we propose a set of nine principles to cover relevant contextual, technical, informational, and stakeholder-sensitive considerations. Transparency by Design is a model that helps organizations design transparent AI systems, by integrating these principles in a step-by-step manner and as an ex-ante value, not as an afterthought.

What constitutes our number concept? What makes it possible for us to employ numbers the way we do; which mental faculties contribute to our grasp of numbers? What do we share with other species, and what is specific to humans? How does our language faculty come into the picture? This 2003 book addresses these questions and discusses the relationship between numerical thinking and the human language faculty, providing psychological, linguistic and philosophical perspectives on number, its evolution and its development in (...) children. Heike Wiese argues that language as a human faculty plays a crucial role in the emergence of systematic numerical thinking. She characterises number sequences as powerful and highly flexible mental tools that are unique to humans and shows that it is language that enables us to go beyond the perception of numerosity and to develop such mental tools.

In this note we argue that Lars von Trier’s movie Dogville can be viewed as an illustration of a simple economy where one agent has only her body as initial endowment. The movie illustrates some interesting comparative statics of equilibrium allocations. It shows how life would be like in a world where, in the absence of constitutional or legal constraints, economic forces reign freely and raises some fundamental issues of voluntary exchange versus force that apply to a number of contentious (...) issues in public debate. JEL codes: A20, D30, D51, D63, F13. Keywords: Dogville, general equilibrium, welfare theorems, comparative statics, international trade, child labor, prostitution, economics education. (shrink)

Heikes challenges Enlightenment rationality's tendency to be an achievement concept which excludes non-whites and non-males. She examines post-Cartesian criticisms of modernism, and pre-modern efforts to address the functional diversity of human cognition, arguing that such approaches offer a rationality that is diverse and morally substantive.

We argue for a perspective on bilingual heritage speakers as native speakers of both their languages and present results from a large-scale, cross-linguistic study that took such a perspective and approached bilinguals and monolinguals on equal grounds. We targeted comparable language use in bilingual and monolingual speakers, crucially covering broader repertoires than just formal language. A main database was the open-access RUEG corpus, which covers comparable informal vs. formal and spoken vs. written productions by adolescent and adult bilinguals with heritage-Greek, (...) -Russian, and -Turkish in Germany and the United States and with heritage-German in the United States, and matching data from monolinguals in Germany, the United States, Greece, Russia, and Turkey. Our main results lie in three areas. We found non-canonical patterns not only in bilingual, but also in monolingual speakers, including patterns that have so far been considered absent from native grammars, in domains of morphology, syntax, intonation, and pragmatics. We found a degree of lexical and morphosyntactic inter-speaker variability in monolinguals that was sometimes higher than that of bilinguals, further challenging the model of the streamlined native speaker. In majority language use, non-canonical patterns were dominant in spoken and/or informal registers, and this was true for monolinguals and bilinguals. In some cases, bilingual speakers were leading quantitatively. In heritage settings where the language was not part of formal schooling, we found tendencies of register leveling, presumably due to the fact that speakers had limited access to formal registers of the heritage language. Our findings thus indicate possible quantitative differences and different register distributions rather than distinct grammatical patterns in bilingual and monolingual speakers. This supports the integration of heritage speakers into the native-speaker continuum. Approaching heritage speakers from this perspective helps us to better understand the empirical data and can shed light on language variation and change in native grammars. Furthermore, our findings for monolinguals lead us to reconsider the state-of-the art on majority languages, given recurring evidence for non-canonical patterns that deviate from what has been assumed in the literature so far, and might have been attributed to bilingualism had we not included informal and spoken registers in monolinguals and bilinguals alike.

We show that there are proper forcings based upon countable trees of creatures that specialise a given Aronszajn tree.

The article takes Helmuth Plessner’s Political Anthropology from 1931 as a postfoundationalist theory of society avant la lettre - which is very similar to the later works of Claude Lefort, Ernesto Laclau, and Chantal Mouffe. Or, the article takes Plessner’s essay as an ‘ontology’ of the Political. After introducing remarks on the historical debates, in which Plessner aimed to intervene, his theory of the Political is reconstructed, within the three categories of ‘unfathomability’, of the constitutive outside, and of the vulnerability (...) of the human body. In a third and last step, Plessner’s most central and most problematic category for the Political - the ‘popular existence’ - is discussed: The ‘people’ is made visible as being a key notion of postfoundational theories of modern democracy, for it is - beneath the ‘Individual’ - one of the imaginary foundations, one of the foundational outsides of a democratically instituted collective.

The article explores the underlying reasons for patients’ self‐perception of being a burden (SPB) in family settings, including its impact on relationships when wishes to die (WTD) are expressed. In a prospective, interview‐based study of WTD in patients with advanced cancer and non‐cancer disease (organ failure, degenerative neurological disease, and frailty) SPB was an important emerging theme. In a sub‐analysis we examined (a) the facets of SPB, (b) correlations between SPB and WTD, and (c) SPB as a relational phenomenon. We (...) analyzed 248 interviews with 62 patients, their family caregivers, and professionals using grounded theory and interpretive phenomenological analysis. SPB appeared as important empathic concern in care situations. Patients expressed many sorts of concerns for others, but also perceived an altered self‐understanding that did not meet mutual expectations within relationships. In SPB associated with WTD three constellations were found: (a) WTD to unburden others; (b) patients decided against hastening death to prevent being a further burden to others (in these cases, the SPB counteracted the wish to die); and (c) both wishes for and against dying were sustained by SPB. These patients often felt paralyzed and suffered deeply. Family caregivers felt emotionally touched by SPB and tried to unburden patients by caring and compassion. We concluded that the impact of SPB on a WTD and the various meanings the facets of SPB have in balancing relationships need to be worked out individually. An early palliative and narrative approach is warranted. (shrink)

Long description: Welche Triebkräfte und Möglichkeitsräume gesellschaftlicher Veränderung verbinden sich mit den Dynamiken des modernen Kapitalismus? Tino Heims breit angelegte Studie zielt auf die Überwindung analytischer Defizite der jüngsten Kapitalismusdebatte. In einer theoriesystematischen Verknüpfung und gegenstandsbezogenen Weiterentwicklung der Analyseraster von Marx, Foucault und Bourdieu - die auch als Kritik dominanter Rezeptionslinien antritt - werden zentrale kapitalistische Funktionslogiken und Krisendynamiken ebenso prägnant analysiert wie historische Transformationen konkreter Modi kapitalistischer Vergesellschaftung. Damit wird zugleich ein Beitrag zur Neubestimmung einer analytisch-kritischen Sozialwissenschaft jenseits normativer (...) Sozialkritik geleistet. (shrink)

We discuss other recent studies on the acquisition of the German plural that do not support the dual-mechanism model. The attested overgeneralizations are not by default only, nor completely random, but predictable from subregularities based on the grammatical gender and the phonology of the noun. In addition, the dual-mechanism model creates a number of problems for acquisition (theory) rather than solving existing ones.

Zeitgleich mit Cassirers erstem Band der „Philosophie der symbolischen Formen“ erscheint mit der „Einheit der Sinne. Grundlinien einer Ästhesiologie des Geistes“ das frühe, weithin unbemerkt gebliebene Hauptwerk Helmuth Plessners. Um Plessners schwieriges Werk in seiner Originalität und darin in seiner Aktualität sichtbar zu machen, werden beide Werke als kulturphilosophische ‚Parallelaktion‘ rekonstruiert, der es darum geht, systematisch die Spannweite der menschlichen Symbolwelten zwischen Mythos bzw. Kunst auf der einen, Wissenschaft auf der anderen Seite zu erschließen.

Drawing on data from a comparative ethnographic study on media usage in transnational families, this paper contributes to a reappraisal of polymedia theory. Two main theoretical assumptions are reconsidered. First, it is demonstrated why the equal availability assumption has to be revised in light of the complex interactions between the corporeal, communicative and social mobilities which together constitute transnational migration. Second, it is argued that the techno-socially accomplished co-presence in transnational families depends more on the creative appropriation and combination of (...) different media channels and communication forms than on the choice between them. In order to empirically investigate the specific needs for, and forms of co-presence in families, the concept of ‘registers of presence’ is proposed. It allows us to understand in detail in what ways and in which constellations transnational families create togetherness with the help of communication technologies. (shrink)

Human cognition is often taken to be a rule-governed system of representations that serve to guide our beliefs about our actions in the world around us. This view, though, has two problems: it must explain how the conceptually governed contents of the mind can be about objects that exist in a non-conceptual world, and it must explain how the non-conceptual world serves as a constraint on belief. I argue that the solution to these problems is to recognize that cognition has (...) both empirical and apriori elements. While neither approach can function in isolation from the other, the empirical approach resolves the first of these problems while apriori structures of rational cognition overcome the second. Taken together, these two views offer a promising solution to the two problems of mental content. (shrink)

Despite decades of management and conservation efforts, we have seen only limited success in rebuilding marine life and restoring ocean ecosystems from human-inflicted damage on a global scale. I suggest that we need to harness both our emotional and rational sides to create a more powerful movement to heal the ocean and rebuild its abundance and diversity. Love and compassion fuel our desire and urge for change and provide a compass that can guide our actions. Science and knowledge provide ways (...) for collecting and interpreting data and information that can enhance our understanding and support our decisions and actions. Combining our emotional and rational sides can inspire our thinking and transform our actions in new, creative ways. In order to affect wide-ranging and long-lasting change, love and knowledge need to work together to transform our collective relationship with the ocean. (shrink)

We give an affirmative answer to Brendle's and Hrušák's question of whether the club principle together with h > N₁ is consistent. We work with a class of axiom A forcings with countable conditions such that q ≥ n p is determined by finitely many elements in the conditions p and q and that all strengthenings of a condition are subsets, and replace many names by actual sets. There are two types of technique: one for tree-like forcings and one for (...) forcings with creatures that are translated into trees. Both lead to new models of the club principle. (shrink)

We consider two models V1, V2 of ZFC such that V1 ⊆ V2, the cofinality functions of V1 and of V2 coincide, V1 and V2 have that same hereditarily countable sets, and there is some uncountable set in V2 that is not covered by any set in V1 of the same cardinality. We show that under these assumptions there is an inner model of V2 with a measurable cardinal κ of Mitchell order κ++. This technical result allows us to show (...) that changing cardinal characteristics without changing cofinalities or ω-sequences has consistency strength at least Mitchell order κ++. From this we get that the changing of cardinal characteristics without changing cardinals or ω-sequences has consistency strength Mitchell order ω1, even in the case of characteristics that do not stem from a transitive relation. Hence the known forcing constructions for such a change have lowest possible consistency strength. We consider some stronger violations of covering which have appeared as intermediate steps in forcing constructions. (shrink)

Fields for Innovative Future Research in History of Science – A Historian of Technology's Perspective. The observations at hand present a historian of technology's perspective and sketch three fields for innovative future research: (past) ‘futures’ and future scenarios in themselves; the challenges as imposed by recent developments in science, technology, and society (e.g. digitization, climate change); and the twisting and flipping of established perspectives (e.g. by focusing on ‘failed’ or ‘old’ science and technology and their declension). Moreover, historians of science, (...) technology, and medicine should participate in emerging transdisciplinary fields such as Environmental Humanities. (shrink)

What social effects does atent architecture have, in which mode of collective existence do nomadic societies such as the Tuareg live? And what kind of fictionally instituted society is accompanied by an architecture that pro duces a non-gestalt of the collective – such as the buried houses in the Chinese Loess? Such analyses show the social positivity of architecture; and they show ex negativo, which kind of social life goes along with immobile constructions.

It is consistent that each union of many families in the Baire space which are not finitely dominating is not dominating. In particular, it is consistent that for each nonprincipal ultrafilter , the cofinality of the reduced ultrapower is greater than . The model is constructed by oracle chain condition forcing, to which we give a self-contained introduction.

Exploring the history of the concept of 'rationality', Deborah K. Hakes argues that feminism should seek to develop a virtue theory of rationality.

We prove that for [Formula: see text] and [Formula: see text] there is a forcing extension with exactly n near-coherence classes of non-principal ultrafilters. We introduce localized versions of Matet forcing and we develop Ramsey spaces of names. The evaluation of some of the new forcings is based on a relative of Hindman’s theorem due to Blass 1987.

Philosophy today is undergoing a transformation away from modernism. The problem is that it is far from clear what this transformation is moving toward. I examine the transition from the premodern to the modern philosophical world and contrast it with our current situation. While the moderns were clear in their rejection of Aristotelian scholasticism and sure of their methods, in our own time we are neither clear about the extent to which we reject modernism nor our methodology moving forward. I (...) argue that the uncertainty of the postmodern philosophical world is, in an important sense, a necessary consequence of the rejection of modernism itself. (shrink)
