Ein christlich-religiöses Verständnis des Lebens ist eng verbunden mit dem Bewusstsein der Grenzen eigener Möglichkeiten bzw. einer spezifischen Verarbeitung des Scheiterns am Vollkommenheitsideal. Dieses Wissen ist nicht nur eine Überzeugung, sondern es wird in der Gestalt vielfältiger Praktiken inkorporiert und verinnerlicht. Der Aufsatz entfaltet diesen Zusammenhang am Beispiel der protestantischen Bestattungskultur in Geschichte und Gegenwart.

Salons evoke high-flown associations; we picture elegant people gathering in glamorous settings for cultivated conversations about the arts, literature, and politics. The so-called salons hosted around 1800 in Berlin by bourgeois Jewish women are tied to promises of emancipation and religious toleration. Scholars have either hailed the empowering functions of these convivial gatherings or debunked their enlightened promises as myths. Drawing on the latest research on conviviality in the social sciences, on Friedrich Schleiermacher's theory of sociability, and on writings by (...) and about Rahel Varnhagen, Henriette Herz and Fanny Lewald, this essay approaches the topic of the salon from a different angle. I argue that these women's social endeavours were not tied to specific ends that we can either admiringly endorse or expose as failures from today's perspective. The notions of the female self, of writing, and the conceptions of literature and philosophy emerging from these convivial constellations are inherently dialogical and shifting. Conversations may sometimes break open hierarchies, but they may also foster conflict and no improvement. The value of these encounters, I suggest, lies in the effort made rather than a classifiable outcome. (shrink)

This paper introduces a logic to reason about a well-known model of opinion dynamics in socialnetworks initially developed by Morris DeGroot as well as Keith Lehrer and Carl Wagner. The proposed logic is an extension of Lukasiewicz' famous fuzzy logic with additional equational expressivity, modal operators, machinery from hybrid logic, and dynamic modalities. The model of opinion dynamics in social networks is simple enough to be easily grasped, but still complex enough to have interesting mathematical properties and applications. Thus, (...) developing a logic to reason about this particular model serves as a paradigmatic example of how logic can be useful in social network analysis. (shrink)

This essay wants to provide a preliminary introduction to, and initial contextualization of the sermons of the seventeenth-century Capuchin preacher Geminianus von Mainz. To my knowledge, his literary production has never been a subject of exhaustive scholarship, even though it has been portrayed by some as a typical example of Bavarian baroque preaching from the later seventeenth century.1 More recently, his metaphorical approach to marriage has been commented upon in passing by Ulrike Strasser and Merry Wiesner-Hanks,2 whereas several culinary (...) remarks in his sermons drew the attention of the late German gastrosopher Christoph Wagner, as can be read in the chapter on 'Barocke...

There is a crisis of valuation practices in the current academic life sciences, triggered by unsustainable growth and “hyper-competition.” Quantitative metrics in evaluating researchers are seen as replacing deeper considerations of the quality and novelty of work, as well as substantive care for the societal implications of research. Junior researchers are frequently mentioned as those most strongly affected by these dynamics. However, their own perceptions of these issues are much less frequently considered. This paper aims at contributing to a better (...) understanding of the interplay between how research is valued and how young researchers learn to live, work and produce knowledge within academia. We thus analyze how PhD students and postdocs in the Austrian life sciences ascribe worth to people, objects and practices as they talk about their own present and future lives in research. We draw on literature from the field of valuation studies and its interest in how actors refer to different forms of valuation to account for their actions. We explore how young researchers are socialized into different valuation practices in different stages of their growing into science. Introducing the concept of “regimes of valuation” we show that PhD students relate to a wider evaluative repertoire while postdocs base their decisions on one dominant regime of valuing research. In conclusion, we discuss the implications of these findings for the epistemic and social development of the life sciences, and for other scientific fields. (shrink)

There has been much interest in group judgment and the so-called 'wisdom of crowds'. In many real world contexts, members of groups not only share a dependence on external sources of information, but they also communicate with one another, thus introducing correlations among their responses that can diminish collective accuracy. This has long been known, but it has-to date-not been examined to what extent different kinds of communication networks may give rise to systematically different effects on accuracy. We argue that (...) equations that relate group accuracy, individual accuracy, and group diversity are useful theoretical tools for understanding group performance in the context of research on group structure. In particular, these equations may serve to identify the kind of group structures that improve individual accuracy without thereby excessively diminishing diversity so that the net positive effect is an improvement even on the level of collective accuracy. Two experiments are reported where two structures are investigated from this perspective. It is demonstrated that the more constrained network outperforms the network with a free flow of information.

Much of what we believe we know, we know through the testimony of others. While there has been long-standing evidence that people are sensitive to the characteristics of the sources of testimony, for example in the context of persuasion, researchers have only recently begun to explore the wider implications of source reliability considerations for the nature of our beliefs. Likewise, much remains to be established concerning what factors influence source reliability. In this paper, we examine, both theoretically and empirically, the (...) implications of using message content as a cue to source reliability. We present a set of experiments examining the relationship between source information and message content in people's responses to simple communications. The results show that people spontaneously revise their beliefs in the reliability of the source on the basis of the expectedness of a source's claim and, conversely, adjust message impact by perceived reliability; hence source reliability and message content have a bi-directional relationship. The implications are discussed for a variety of psychological, philosophical and political issues such as belief polarization and dual-route models of persuasion. (shrink)

ABSTRACTWhat is the relation between ethical reflection and moral behavior? Does professional reflection on ethical issues positively impact moral behaviors? To address these questions, Schwitzgebel and Rust empirically investigated if philosophy professors engaged with ethics on a professional basis behave any morally better or, at least, more consistently with their expressed values than do non-ethicist professors. Findings from their original US-based sample indicated that neither is the case, suggesting that there is no positive influence of ethical reflection on moral action. (...) In the study at hand, we attempted to cross-validate this pattern of results in the German-speaking countries and surveyed 417 professors using a replication-extension research design. Our results indicate a successful replication of the original effect that ethicists do not behave any morally better compared to other academics across the vast majority of normative issues. Yet, unlike the original study, we found mixed results o... (shrink)

Modeling of evolution and development of language has principally utilized mature units of spoken language, phonemes and words, as both targets and inputs. This approach cannot address the earliest phases of development because young infants are unable to produce such language features. We argue that units of early vocal development—protophones and their primitive illocutionary/perlocutionary forces—should be targeted in evolutionary modeling because they suggest likely units of hominin vocalization/communication shortly after the split from the chimpanzee/bonobo lineage, and because early development of (...) spontaneous vocal capability is a logically necessary step toward vocal language, a root capability without which other crucial steps toward vocal language capability are impossible. Modeling of language evolution/development must account for dynamic change in early communicative units of form/function across time. We argue for interactive contributions of sender/infants and receiver/caregivers in a feedback loop involving both development and evolution and propose to begin computational modeling at the hominin break from the primate communicative background.

Descartes' Meditations is one of the most thoroughly analyzed of all philosophical texts. Nevertheless, central issues in Descartes' thought remain unresolved, particularly the problem of the Cartesian Circle. Most attempts to deal with that problem have weakened the force of Descartes' own doubts or weakened the goals he was seeking. In this book, Stephen I. Wagner gives Descartes' doubts their strongest force and shows how he overcomes those doubts, establishing with metaphysical certainty the existence of a non-deceiving God and (...) the truth of his clear and distinct perceptions. Wagner's innovative and thorough reading of the text clarifies a wide range of other issues that have been left unclear by previous commentaries, including the nature of the cogito discovery and the relationship between Descartes' proofs of God's existence. His book will be of great interest to scholars and upper-level students of Descartes, early modern philosophy and theology. (shrink)

The proposed volumes are aimed at a multidisciplinary audience and seek to fill the gap between law, semiotics and visuality providing a comprehensive theoretical and analytical overview of legal visual semiotics. They seek to promote an interdisciplinary debate from law, semiotics and visuality bringing together the cumulative research traditions of these related areas as a prelude to identifying fertile avenues for research going forward. Advance Praise for Law, Culture and Visual Studies This diverse and exhilarating collection of essays explores the (...) many facets both historical and contemporary of visual culture in the law. It opens a window onto the substantive, jurisdictional, disciplinary and methodological diversity of current research. It is a cornucopia of materials that will enliven legal studies for those new to the field as well as for established scholars. It is a 'must read' that will leave you wondering about the validity of the long held obsession that reduces the law and legal studies to little more than a preoccupation with the word. Leslie J Moran Professor of Law, Birkbeck College, University of London Law, Culture and Visual Studies is a treasure trove of insights on the entwined roles of legality and visuality. From multiple interdisciplinary perspectives by scholars from around the world, these pieces reflect the fullness and complexities of our visual encounters with law and culture. From pictures to places to postage stamps, from forensics to film to folklore, this anthology is an exciting journey through the fertile field of law and visual culture as well as a testament that the field has come of age. Naomi Mezey, Professor of Law, Georgetown University Law Center, Washington, D.C., USA This highly interdisciplinary reference work brings together diverse fields including cultural studies, communication theory, rhetoric, law and film studies, legal and social history, visual and legal theory, in order to document the various historical, cultural, representational and theoretical links that bind together law and the visual. This book offers a breath-taking range of resources from both well-established and newer scholars who together cover the field of law's representation in, interrogation of, and dialogue with forms of visual rhetoric, practice, and discourse. Taken together this scholarship presents state of the art research into an important and developing dimension of contemporary legal and cultural inquiry. Above all, Law Culture and Visual Studies lays the groundwork for rethinking the nature of law in our densely visual culture: How are legal meanings produced, encoded, distributed, and decoded? What critical and hermeneutic skills, new or old, familiar or unfamiliar, will be needed? Topical, diverse, and enlivening, Law Culture and Visual Studies is a vital research tool and an urgent invitation to further critical thinking in the areas so well laid out in this collection.

The Cognitive Estimation Test is widely used by clinicians and researchers to assess the ability to produce reasonable cognitive estimates. Although several studies have published normative data for versions of the CET, many of the items are now outdated and parallel forms of the test do not exist to allow cognitive estimation abilities to be assessed on more than one occasion. In the present study, we devised two new 9-item parallel forms of the CET. These versions were administered to 184 (...) healthy male and female participants aged 18–79 years with 9–22 years of education. Increasing age and years of education were found to be associated with successful CET performance as well as gender, intellect, naming, arithmetic and semantic memory abilities. To validate that the parallel forms of the CET were sensitive to frontal lobe damage, both versions were administered to 24 patients with frontal lobe lesions and 48 age-, gender- and education-matched controls. The frontal patients’ error scores were significantly higher than the healthy controls on both versions of the task. This study provides normative data for parallel forms of the CET for adults which are also suitable for assessing frontal lobe dysfunction on more than one occasion without practice effects.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:The Last Man by Mary ShelleyJennifer A. Wagner-LawlorMary Shelley. The Last Man. 1826. Edited by Chris Washington. Norton Critical Editions. New York: W. W. Norton, 2023. xxiv + 571 pp. Paperback, ISBN 9780393887822.New critical editions of well-known literary works serve several important functions, and those designed specifically for students serve two of the most important: to introduce readers to texts that were overlooked during and since the (...) author’s time, but that might find greater favor today; and to re-introduce to a new generation of students classic texts that have lost critical favor or been neglected. Mary Shelley’s The Last Man (1826) is a novel long overshadowed by brilliance and resilient legacy of her first novel, Frankenstein (1818), written at a mere eighteen years of age. As so often happened to nineteenth-century women who published under their own names, both Frankenstein and The Last Man were hammered critically by male reviewers (and often by the few female ones) unable to believe any woman, and certainly no “good” woman, could compose these stories. And by 1826, Mary Shelley had already gained notoriety thanks to her association with the radical politics and “free-loving” Shelley-Byron circle). No wonder then that contemporaneous reviewers—even as they brought themselves to compliment the narratological and formal accomplishment the novel represents—could not countenance either its content or its author, as the novel “violated” certain forms of literary and gender propriety: indeed, the novel was deemed the product of a “diseased imagination” (The Monthly Review).Modern assessments of the novel are far more admiring of Shelley’s sophisticated examination of national and cultural mythic structuralizations, and receptive to the boldness of Shelley’s profoundly ironical assessments of them. In this new Norton Critical Edition of The Last Man, Chris Washington comes to the text with a refreshingly undeferential approach to Shelley’s Romantic forebears and immediate companions. Not because they [End Page 582] deserve being knocked off their pedestals, but because—granting all that—Shelley’s text has a lot more to give to us. This is the first time the Norton Critical Edition series has produced an annotated critical edition of The Last Man (Broadview’s appeared in 1996), and it is therefore both welcome and well overdue. For this reader, The Last Man is in some ways arguably superior to Frankenstein, certainly better written and developed. Frankenstein packs the greater punch, but The Last Man picks up and reweaves, on a much larger loom, the same thematic threads: justice and judgment; hospitality and generosity; family love and ethical obligation to community and nation; “civilized” and “wild” spaces. These themes are figured not only in terms of landscape but also in terms of geopolitical organization (i.e., the West vs. “the East,” presumed source of the virus); the bounded- vs. unbound-ness of the creative imagination (also tied to cultural notions of civilization and wilderness); solitude and loneliness; alienness and otherness; alienation and self-alienation and/as dehumanization; the human and the posthuman. While part of Frankenstein’s greatness is its narrative concision and stylistic spareness, the greatness of The Last Man, written by the more mature writer, intellectually and technically (and without the interference of Percy Shelley), is how fully Shelley “fleshes out” those entanglements in this later novel.Setting aside therefore the inclusion of “the usual suspects” (xx) of earlier editions, Washington gives space to critical approaches that are not focused so intensely on the influences of Shelley’s biography. In an excellent introduction Washington emphasizes the various ways in which this novel opens up to (still) intractable political and human rights issues: slavery, imperialism, nonheteronormative genders and sexualities, and precarious lives.Washington addresses particularly what Shelley’s text has to offer—and does offer—to today’s students. He shares his own experience of teaching this novel during COVID times, finding the students, used to speed of communication and multimedia delivery, resistant initially to the narrative’s pacing, and reintroducing them to the pleasures of the slow build-up of plot and setting, as well as the excruciating tension of watching a slow-burn approach to seemingly unavoidable catastrophe. But Washington rejects... (shrink)

How Do Pictures Act? Two Semiotic Aspects of Picture Activity/Frederik Stjernfelt, s. 19-26, ill.

A decision problem in which the values of the decision variables must sum to a fixed positive real number s is called an "allocation problem," and the problem of aggregating the allocations of n experts the "allocation aggregation problem." Under two simple axiomatic restrictions on aggregation, the only acceptable allocation aggregation method is based on weighted arithmetic averaging (Lehrer and Wagner, Rational Consensus in Science and Society, 1981). In this note it is demonstrated that when the values assigned to (...) the variables are restricted to a finite set (as is always the case in practice), the aforementioned axioms allow only dictatorial aggregation.

Accountability in Education discusses the debate surrounding the accountability of teachers and questions the responsibility that parents, other groups and even children themselves have for their experience at school. In this book, Robert Wagner examines the assumptions underlying criticisms of major institutions for their lack of attention to the ethical and practical ramifications of their policies. Wagner questions the validity of this assumption by analyzing accountability relationships in schools, discussing the responsibility students have for the quality of their (...) own experiences--as well as the potential accountability of parents and other groups--and relating the issue of accountability in education to questions of moral and legal obligation in areas such as business, government and law. His book provides a cogent philosophical analysis of accountability and is invaluable to an understanding of a majour issue in the contemporary discussion of education. (shrink)

Among the many sorts of problems encountered in decision theory, allocation problems occupy a central position. Such problems call for the assignment of a nonnegative real number to each member of a finite set of entities, in such a way that the values so assigned sum to some fixed positive real number s. Familiar cases include the problem of specifying a probability mass function on a countable set of possible states of the world, and the distribution of a certain sum (...) of money, or other resource, among various enterprises. In determining an s-allocation it is common to solicit the opinions of more than one individual, which leads immediately to the question of how to aggregate their typically differing allocations into a single “consensual” allocation. Guided by the traditions of social choice theory decision theorists have taken an axiomatic approach to determining acceptable methods of allocation aggregation. In such approaches so-called “independence” conditions have been ubiquitous. Such conditions dictate that the consensual allocation assigned to each entity should depend only on the allocations assigned by individuals to that entity, taking no account of the allocations that they assign to any other entities. While there are reasons beyond mere simplicity for subjecting allocation aggregation to independence, this radically anti-holistic stricture has frequently proved to severely limit the set of acceptable aggregation methods. As we show in what follows, the limitations are particularly acute in the case of three or more entities which must be assigned nonnegative values summing to some fixed positive number s. For if the set V⊆[0,s] of values that may be assigned to these entities satisfies some simple closure conditions and Vis finite, then independence allows only for dictatorial or imposed aggregation. This theorem builds on and extends a theorem of Bradley and Wagner and, when V={0,1}, yields as a corollary an impossibility theorem of Dietrich on judgment aggregation. (shrink)

Educational reformers all around the globe are continuously searching for ways to make schools more effective and efficient. In Germany, this movement has led to reforms that reduced overall school time of high track secondary schools from 9 to 8 years, which was compensated for by increasing average instruction time per week in lower secondary school. Based on prior research, we assumed that this reform might increase gender disparities in STEM-related outcomes, stress, and health because it required students to learn (...) similar content in less amount of time. Therefore, we investigated how the school time reform affected gender disparities at the end of upper secondary school between 2011 and 2013. Specifically, we considered representative data of the last two cohorts who completed lower secondary school before the reform and the first two cohorts after the reform from the National Educational Panel Study. Potential differences in gender disparities were investigated for upper secondary school outcomes of subject-specific standardized test performance, self-concept, and interest in mathematics, biology and physics, as well as outcomes of school-related stress and health. Overall, we found substantial disparities between girls and boys, which seemed to change little after the reform. Exceptions were the statistically significant gender × reform interactions for one stress dimension and two health dimensions which increased for both boys and girls, but more strongly for girls.

Comparative analysis of civilizations has recently revived and has led into a debate about varieties of modernity. This connection between an empirically defined area of study, `civilizations', and a theme that is predominantly seen as conceptual, `modernity', is a peculiar one and raises crucial questions for any social theory. Can `modernity' be located spatio-temporally among the civilizations? Is it itself a civilization (or the successor to all civilizations), or does it not rather refer to a human condition? This article takes (...) its starting point from the observation that civilizational comparison is always some form of cultural analysis and asks if and how a cultural theory of modernity is possible and fruitful under current theoretical and historical conditions.

Mitochondrial function and biogenesis depend on the transport of a large variety of proteins, ions, and metabolites across the two surrounding membranes. While several specific transporters are present in the inner membrane, transport processes across the outer membrane are less understood. Recent studies reveal that the number of outer membrane channels and their transport mechanisms are more diverse than originally thought. Four protein‐conducting channels promote transport of distinct sets of precursor proteins across and into the outer membrane. The voltage‐dependent anion (...) channel (VDAC) forms the major channel for small hydrophilic molecules. In addition, three channels with yet unknown substrate specificity exist in the outer membrane. In this review, we outline the emerging functional diversity, selectivity, and regulation of mitochondrial outer membrane channels. The presence of several channel‐forming proteins challenges the traditional view that the outer membrane forms an unspecific size‐exclusion filter for the flux of small hydrophilic molecules.

Nowadays psychology as a scientific discourse and a positive practice finds itself in an epistemologically critical situation. The analysis of the actual state of the academic discussion in cognitive-behavioural psychology, the most representative and widespread theoretical-practical trend in European nations, reveals that it frequently is misunderstood as a exclusively technical proceeding, an amount of deficiently articulated operatory interventions, alienated from its underlying anthropological assumptions. This paper proposes to exam how far the gap between theoretical reflection and effective practice, a cleavage (...) frequently confirmed, may be reduced discussing the concept of Menschenbildannahmen, an idea firmly rooted in anthropological thinking. Actualmente, la psicología en tanto discurso científico y práctica positiva se encuentra en un estado epistemológicamente crítico. El análisis del estado actual de la discusión académica en la psicología cognitivo-conductual, la corriente teórico-práctica más representativa y más difundida en los estados europeos, devela que ésta frecuentemente es malentendida como un mero procedimiento técnico, un conjunto precariamente articulado de intervenciones operatorias, desentendidas de sus supuestos antropológicos subyacentes. Se propone examinar en qué medida la brecha entre reflexión teórica y práctica efectiva, una escisión ampliamente constatada, puede ser aminorada sometiendo a discusión el concepto de las Menschenbildannahmen, de extensa raigambre en el pensamiento antropológico.

This article studies Ibn al-Haytham’s treatment of the common notions from Euclid’s Elements (usually referred to today as the axioms). We argue that Ibn al-Haytham initiated a new approach with regard to these foundational statements, rejecting their qualification as innate, self-evident, or primary. We suggest that Ibn al-Haytham’s engagement with experimental science, especially optics, led him to revise the framing of Euclidean common notions in a way that would fit his experimental approach.

Benedictus de Spinoza (1632-1677), filósofo seiscentista holandês, não dedicou, evidentemente, ao tema da educação uma obra sistemática. No entanto, de maneira um pouco dispersa, ele deixou alguns registros sobre o ato de educar e sua importância em termos ontológicos, epistemológicos, afetivos e ético-políticos. Com base nisso, o objetivo desta pesquisa se dará a partir das seguintes reflexões: Por que estudar um pensador como Spinoza para entender a educação hoje? Qual a importância de sua filosofia às aplicações pedagógicas contemporâneas na Escola? (...) Quais soluções o pensamento spinozano poderia oferecer aos entraves e às crises no sistema educacional? Para tanto, nossa fundamentação tem como principal referencial teórico para a realização deste artigo, Ética, considerada a obra prima de Spinoza, e outros escritos, como o Tratado da Emenda do Intelecto e a Correspondência. Ademais, sobre o tema da educação, teremos como base os pesquisadores spinozanos: Rabenort, Ravà, Juliana Merçon, dentre outros. Conclui-se que as leituras e análises dos textos spinozanos possibilitaram que evidenciássemos algumas contribuições à educação contemporânea, ao enfatizarmos a importância da ética e da afetividade para se pensar numa educação mais potente, ou seja, mais ativa e livre. Com base nisso, possibilitou-se uma discussão sobre o papel dos chamados afetos alegres para se pensar a prática pedagógica à luz da filosofia spinozana. (shrink)

Gyenis and Rédei (G&R) have shown that any prior _p_ on a finite algebra _A_, however chosen, significantly restricts the set of posteriors derivable from _p_ by Jeffrey conditioning (JC) on a nontrivial measurable partition (i.e., a partition consisting of members of _A_, at least one of which is not an atom of _A_). They support this claim by proving that the set of potential posteriors _not derivable_ from _p_ in this way, which they call the _Bayes blind spot of (...) p_, is large, having cardinality _c_ and normalized Lebesgue measure 1, as well as being of second Baire category for a natural metrizable topology. In the present paper, we establish results analogous to those of G&R for probability measures on any infinite sigma algebra of subsets of a countably infinite set (which requires distinctly different treatments of the topological and measure-theoretic cases). We also show, in both the finite and infinite cases, that all of the limitative results for a single prior _p_ continue to hold for the intersection of the Bayes blind spots of countably many priors. This leads us to reject the claim of G&R that the large size of blind spots in the single prior case is attributable to the limitations imposed by priors. We argue instead that it is the so-called _rigidity property_ of JC that accounts for the large size of Bayes blind spots. G&R also prove that _any_ potential posterior _q_ can be derived from a prior _p_ by at most two applications of JC on nontrivial partitions. But they remark that their particular two-stage derivation of an \(r \in BS(p)\) from _p_ is barely distinguishable from a single, complete reassessment on a trivial partition. We show, however, that there are two-stage derivations of _r_ from _p_ that require no direct assessment of the probability of any atom at either stage. Finally, in order to situate the aforementioned limitative results in the proper context, we demonstrate that a probability revision that would amount to complete reassessment within a Jeffrey evidentiary framework may arise, in a different evidentiary framework, in a way that involves no direct assessment of the probability of any atom, as, for example, in a generalization of Jeffrey’s solution to the problem of old evidence and new explanation.
