This paper describes an exploratory comparative study of knowledge workers and their challenges in high tech global project teams. More specifically we focus on the tension between perceived collocation and actual geographical distributed project work as a function of: (1) the demand to distribute and shift attention in multi-teaming, (2) virtuality i.e. number of virtual teams participants engage in, (3) the continuous adjustment and re-adjustment to new places they perform their activity, and (4) the collaboration technologies they use. We present (...) the methodology for data collection that included semi-structured interviews, surveys, and on site shadowing of the project participants, and discuss the findings from the data analysis. The study is based on the bricks-bits-interaction framework. It is at the intersection of the design of physical spaces, i.e., bricks; rich digital information and collaboration technology (ICT) content, mobile devices and network infrastructures, i.e., bits, and emergent work practices, process, and new ways people behave in communicative events using the affordances of ICT augmented physical, virtual spaces and digital content, i.e., interaction.

A key challenge faced by organizations is to provide project teams with workspaces, information, and collaboration technologies that fosters creativity and high-performance team productivity. This requires understanding the relation between and impacts of (1) workspace, (2) activity and content that is created, and (3) social, behavioral, and cognitive aspects of work. This paper describes an exploratory study of everyday activities in the context of knowledge work in a shared workspace used by a high-tech global design team that explores future products. (...) The study formalizes key elements for productive knowledge work as a function of tasks, context, and team. It identifies enablers, hindrances, and requirements for physical, virtual, and social work environments. The study identified, through semi-structured interviews, surveys, and on-site shadowing, a key workspace component that facilitates dynamic participation of all team members. This workspace component is a wall used as a large, public, physical display surface for project content (the WALL). The WALL acts as a mediator for individual reflection-in-action and team reflection-in-interaction. It serves as “social glue” both between individuals and between geographically distributed subgroups. (shrink)

The aim of this article is to elucidate the processes that characterize natural language interpretation. The basic hypothesis is that natural language interpretation can be characterized as an optimization problem. This innovative view on interpretation is shown to account for the crucial role of contextual information while avoiding certain well-known problems associated withcompositionality. This will become particularly clear in the context of incomplete expressions. Our approach takes as a point of departure total freedom ofinterpretation in combination with the parallel application (...) of soft constraints on possible interpretations. These constraints can be contextual, intonational or syntactic in nature. The integration of pragmatic andsyntactic/semantic information in a system of ranked constraints is proposed to correctly derive the optimal interpretations in cases of nominal anaphorization, determiner quantification and elliptical comparatives.

The topic of this thesis is how we should treat tiny probabilities of vast value. This thesis consists of six independent papers. Chapter 1 discusses the idea that utilities are bounded. It shows that bounded decision theories prescribe prospects that are better for no one and worse for some if combined with an additive axiology. Chapter 2, in turn, points out that standard axiomatizations of Expected Utility Theory violate dominance in cases that involve possible states of zero probability. Chapters 3–6 (...) discuss the idea that we should ignore tiny probabilities in practical decision-making. Chapter 3 argues that discounting small probabilities solves the ‘Intrapersonal Addition Paradox’ and thus helps avoid the Repugnant Conclusion. Chapter 4 explores what the most plausible version of this view might look like and what problems the different versions have. Chapter 5 focuses on one type of problem, namely, money pumps. The Independence Money Pump, in particular, presents a difficult challenge for those who wish to discount small probabilities. Finally, Chapter 6 discusses the implications of discounting small probabilities for the value of the far future. (shrink)

This paper is a contribution to the development of model theory of fuzzy logic in narrow sense. We consider a formal system EvŁ of fuzzy logic that has evaluated syntax, i. e. axioms need not be fully convincing and so, they form a fuzzy set only. Consequently, formulas are provable in some general degree. A generalization of Gödel's completeness theorem does hold in EvŁ. The truth values form an MV-algebra that is either finite or Łukasiewicz algebra on [0, 1].The classical (...) omitting types theorem states that given a formal theory T and a set Σ of formulas with the same free variables, we can construct a model of T which omits Σ, i. e. there is always a formula from Σ not true in it. In this paper, we generalize this theorem for EvŁ, that is, we prove that if T is a fuzzy theory and Σ forms a fuzzy set , then a model omitting Σ also exists. We will prove this theorem for two essential cases of EvŁ: either EvŁ has logical constants for all truth values, or it has these constants for truth values from [0, 1] ∩ ℚ only. (shrink)

This paper explores structuralism as a way to model theories from scientific practice. As a case study I analyzed a theory about the dynamics of the basal ganglia, a part of the brain that is involved in Parkinson's disease. After introducing the case study I explore how to structurally represent qualitative assumptions about disease, intervention and dynamical systems in general. I further explicate the structure of the basal ganglia theory in detail, how it explains Parkinson's disease and how it implies (...) treatments. I close with a consideration of how a structuralist representation could be useful in practice to explore and develop theories with the aid of a computer. (shrink)

The article briefly introduces an academic debate between two different responses to the predicament of the human in the ecological crisis, namely the object-oriented ontology and the vitalist response to that approach. Based on that introduction, it argues for the need of a complementing analytical tool and sketches the contours of such a tool by suggesting an epistemological tactic for a decolonizing human distinctiveness. The article suggests an analytical maneuver to be used by scholars who aim at decolonizing nature from (...) human oppression, a tool that enables illumination and critical scrutiny of the epistemological role of the human as one stage toward destabilizing the notion of human distinctiveness. The article, thus, introduces an approach where human distinctiveness is not understood as a factual distinctiveness—not an essential difference between the human and the nonhuman world—but where human distinctiveness is critically viewed as a discursive role in theoretical work, a role that can be temporarily put to use by the scholar as a decolonizing epistemological tactic. In other words, human distinctiveness is here tactically used as a tool to critically scrutinize the idea of human distinctiveness rather than to safeguard it. (shrink)

Heidegger hielt die unter dem Titel Geschichte des Zeitbegriffs angekundigte Vorlesung im Sommer-Semester 1925 in der Marburger Universitat. Er gelangte jedoch nicht mehr zur Ausfuhrung der zentralen Thematik. Der Themenkreis der Vorlesung ist mit der Nennung des Untertitels abgesteckt: Prolegomena zu einer Phanomenologie von Geschichte und Natur. Heideggers thematische Uberlegungen beginnen mit einer Kennzeichnung der Situation von Philosophie und Wissenschaft in der zweiten Halfte des 19. Jahrhunderts und stellen das seiner Deutung nach entscheidende Ereignis dieser Zeit heraus: den Durchbruch der (...) Phanomenologie als philosophische Forschung. Er untersucht ihre wesentlichen Entdeckungen, verteidigt sie gegen Missverstandnisse, um dann seinerseits Kritik vorzubringen, wo die Phanomenologie ihrer Forderung zu den Sachen selbst nicht gerecht wird.

Nebel argues for the Repugnant Conclusion via the “Intrapersonal Repugnant Conclusion,” on which certainty of a mediocre life is better for individuals than a sufficiently small chance of an excellent life. In this article, I deny that acceptance of the Intrapersonal Repugnant Conclusion leads us to the Repugnant Conclusion. I point out that on many views which avoid the Repugnant Conclusion we should discount very small probabilities down to zero. If we do, then Nebel’s crucial premise of Ex Ante Pareto (...) fails, because discounting at the individual level can fail to match up with discounting at the population level. (shrink)

IntroductionLittle is known about risk factors for both Long COVID and somatic symptoms that develop in individuals without a history of COVID-19 in response to the pandemic. There is reason to assume an interplay between pathophysiological mechanisms and psychosocial factors in the etiology of symptom persistence.ObjectiveTherefore, this study investigates specific risk factors for somatic symptom deterioration in a cohort of German adults with and without prior SARS-CoV-2 infection.MethodsGerman healthcare professionals underwent SARS-CoV-2 IgG antibody testing and completed self-rating questionnaires at baseline (...) and 21 months later between April 2020 and February 2022. Differences in variables between the time points were analyzed and a regression analysis was performed to predict somatic symptom deterioration at follow-up.ResultsSeven hundred fifty-one adults completed both assessments. Until follow-up, n = 58 had contracted SARS-CoV-2 confirmed by serology. Between baseline and follow-up, signs of mental and physical strain increased significantly in the sample. Symptom expectations associated with COVID-19 and a self-reported history of COVID-19, but not serologically confirmed SARS-CoV-2 infection, significantly predicted somatic symptom deterioration at follow-up. A further predictor was baseline psychological symptom burden.ConclusionsThis study supports a disease-overarching biopsychosocial model for the development of burdensome somatic symptoms during the COVID-19 pandemic and supports research findings that symptom burden may be more related to the psychosocial effects of the pandemic than to infection itself. Future studies on Long COVID should include SARS-CoV-2 negative control groups and consider symptom burden prior to infection in order to avoid an overestimation of prevalence rates. (shrink)

Regarding the question of “theory”, the paper takes the perspective of creation, i. e. of producing texts that exhibit theoretical qualities and that in this sense both do justice to a – certainly complex – “function” of philosophical theory and also “work” as theory (namely in a sustainable way, and perhaps also beyond the current scientific orthodoxies) and can thus be received in the long line of the philosophically relevant reading canon. On the one hand, it is proposed to take (...) the project character of philosophical theory seriously. On the other hand, the conditions for the success of philosophical (theoretical) prose have to be looked at carefully. In addition to scholarship and a critical concern with and deep knowledge of discourse, literary qualities are also relevant. There is interplay between time-bound – i. e. historically changing – requirements and a paradoxically persistent style of philosophizing that proceeds despite the plurality of canonical references. “Philosophy”, of course, is not something timeless; it remains something provincial on an intercultural scale and, in principle, something that can be lost.

While largely studied because of their harmful effects on human health, there is growing appreciation that bacteria are important partners for invertebrates and vertebrates, including man. Epithelia in metazoans do not only select their microbiota; a coevolved consortium of microbes enables both invertebrates and vertebrates to expand the range of diet supply, to shape the complex immune system and to control pathogenic bacteria. Microbes in zebrafish and mice regulate gut epithelial homeostasis. In a squid, microbes control the development of the (...) symbiotic light organ. These discoveries point to a key role for bacteria in any metazoan existence, and imply that beneficial bacteria‐host interactions should be considered an integral part of development and evolution.

Originally presented as the author's thesis, Heidelberg, 1977.

To address an ethics of refusal in higher education is to wager in the name of future possibles not already governed by the extractive politics of colonial progress and oppressive regimes of knowing and doing. In this essay, Petra Mikulan shows American pragmatism to have always been, in a certain sense, post-Anthropocene in its condition of emergence, bound up with settler colonialism and its extractive geopolitics. However, pragmatism in its speculative trust can also help engage education in thinking of (...) a future that does not belong to a presupposed humanity and its “nature” by dramatizing a certain insistence of educational institutions on maintaining comfort and trust in the “common good.” What is at stake in education facing planetary ecological devastation and intensified racial and social injustices, Mikulan contends, is an ethics of refusal of institutionalized learning, knowing, and doing tout court, particularly if these educational regimes continue to insist on governing what are deemed the only possible (and thus impossible) enactments of education.

Fiodor Dostoievski rasga el alma humana hasta dejarla herida por el sufrimiento, la culpa y el aislamiento. Y, sin embargo, la derrota no gana la batalla. La escritora sureña estadounidense Carson McCullers escribe sobre la soledad y la miseria del sur de los Estados Unidos con una mirada atenta a los paisajes desolados de la Rusia de Fiodor Dostoievski, no sólo físicos sino esencialmente metafísicos. Esta autora que ya leyó al maestro ruso a los 13 años explora las entrañas humanas (...) desde un terreno rural, desolador, inhóspito y desafortunado, con diferencias raciales, sobreexposición de alcohol y con un concepto de bien moral interno que aparece como una pulsión constante e inagotable. En esta aproximación queremos destacar cómo el misterio del mal, pero también el acto de la voluntad y la incomunicación, son aspectos que unen a ambos autores, especialmente en dos de sus obras maestras, Crimen y Castigo y El corazón es un cazador solitario, respectivamente.

Six experiments investigated variables predicted to influence subjects’ tendency to classify items by a single property instead of overall similarity, following the paradigm of Norenzayan et al., who found that European Americans tended to give more “logical” rule-based responses. However, in five experiments with Mechanical Turk subjects and undergraduates at an American university, we found a consistent preference for similarity-based responding. A sixth experiment with Korean undergraduates revealed an effect of instructions, also reported by Norenzayan et al., in which classification (...) instructions led to majority rule-based responding but similarity instructions led to overall similarity grouping. Our American subjects showed no such difference and used similarity more overall. We conclude that Americans do not have a preference for rule responding in classification and discuss the differences between tasks that reliably show strong rule or unidimensional preferences in contrast to this classification paradigm.

While action selection strategies in well‐defined domains have received considerable attention, little is yet known about how people choose what to do next in ill‐defined tasks. In this contribution, we shed light on this issue by considering everyday tasks, which in many cases have a multitude of possible solutions (e.g., it does not matter in which order the items are brought to the table when setting a table) and are thus categorized as ill‐defined problems. Even if there are no hard (...) constraints on the ordering of subtasks in everyday activities, our research shows that people exhibit specific preferences. We propose that these preferences arise from bounded rationality, that is, people only have limited knowledge and processing power available, which results in a preference to minimize the overall physical and cognitive effort. In the context of everyday activities, this can be achieved by (a) taking properties of the spatial environment into account to use them to one's advantage, and (b) employing a stepwise‐optimal action selection strategy. We present the Opportunistic Planning Model as an explanatory cognitive model, which instantiates these assumptions, and show that the model is able to generalize to new everyday tasks, outperforming machine learning models such as neural networks during generalization.

Relational spaces are variable patterns which establish an order of the coexisting. In them, forces of dispersion come into effect that form positional relationships and neighborhoods. In line with the philosophical concept of relational space, the paper sketches a media ecology of coexistence, of the simultaneous juxtaposition of the scattered, and envisages an ethics and aesthetics of distribution. Starting with Martin Heidegger's ontological postulate of an »original dispersion of existence« and its post-structuralist and philosophical critique, various concepts of relational spaces (...) and regimes of dispersion are discussed. German Relationale Räume sind veränderliche Gefüge, die eine Ordnung des Koexistierenden etablieren. In ihnen sind Kräfte der Streuung wirksam, die Lagebeziehungen und Nachbarschaften ausbilden. Der Beitrag entwirft ausgehend vom philosophischen Konzept des Relationsraums eine Medienökologie der Koexistenz, des gleichzeitigen Nebeneinanders des Zerstreuten, und zielt auf eine Ethik und Ästhetik der Verteilung. Ausgehend von Martin Heideggers fundamentalontologischer Setzung einer »ursprünglichen Streuung des Daseins« und deren poststrukturalistischen und philosophischen Kritik werden Konzepte variabler Relationsräume und Regime der Zerstreuung diskutiert.

Wnt proteins can activate different intracellular signaling cascades in various organisms by interacting with receptors of the Frizzled family. The first identified Wnt signaling pathway, the Wnt/β‐catenin pathway, has been studied in much detail and is highly conserved among species. As to non‐canonical Wnt pathways, the current situation is more nebulous partly because the intracellular mediators of this pathway are not yet fully understood and, in some cases, even identified. However, there are increasing data that prove the existence of non‐canonical (...) Wnt signaling and demonstrate its involvement in different developmental processes. In vertebrates, Wnt‐11 and Wnt‐5A can activate the Wnt/JNK pathway, which resembles the planar cell polarity pathway in Drosophila. The Wnt/Ca2+‐pathway has only been described in Xenopus and zebrafish so far and it is unclear whether it also exists in other organisms. Two recent papers provide us with new insight into non‐canonical Wnt signaling by (1) presenting a new intracellular mediator of non‐canonical signaling in Xenopus1 and (2) implicating the existence of an additional non‐canonical Wnt signaling pathway in flies.2 BioEssays 24:881–884, 2002. © 2002 Wiley Periodicals, Inc.

Substance-abusing women are vulnerable to specific kinds of epistemic injustice, including stigmatization and discrimination. This article examines the development of the epistemic agency of female substance abusers by asking: How does the use of a formal discussion protocol in community rehabilitation interaction alleviate epistemic injustice and strengthen the epistemic agency of substance abusers? The data were collected in a Finnish rehabilitation center by videotaping six group discussions between social workers, peer support workers, and rehabilitation clients with substance abuse problems. Of (...) these data, one recorded group discussion between four female participants—two rehabilitation clients, a peer support worker, and a social adviser—was used in this paper. Using conversational analysis, the findings indicate that, through the collaborative activities of sharing experiential knowledge about substance abuse and discussing the experiences of abuse in the rehabilitation interaction, substance abusers can develop novel ways to strengthen their epistemic agency by enhanced self-awareness. The discussion protocol is an epistemic tool that professionals and clients can learn to use in ethically and epistemologically successful ways in interaction. The use of a discussion protocol is an example of social professionals’ clinical knowledge of intensifying collaboration and sharing experiential knowledge in community rehabilitation and other substance abuse services.

This article explores the extent to which a feminist reading of gender mainstreaming is incorporated in the EU political discourse by analysing how family policy and gender inequality in politics are framed in EU policy documents. Gender mainstreaming is treated as an open signifier that can be filled with both feminist and non-feminist content. The article provides a set of criteria to assess whether a feminist reading of gender mainstreaming has been adopted. The frame analysis of EU documents on family (...) policy and gender inequality in politics reveals but a partial adoption of a feminist understanding of gender mainstreaming and only in the area of gender inequality in politics.

This commentary focuses on affective structures and the main adaptive functions of shared narratives to fill the gaps of the Conviction Narrative Theory. The transmission of narratives among individuals in highly uncertain situations is irrevocably tainted by affects and anchored in collective memory. Narratives have important evolutionary functions for human beings under threat and act as the social glue that creates and strengthens social bonds among individuals.

Die Sprache weiß, wovon sie spricht. Das zeigt sich im Kompositum "ef?μe ", von dem das deutsche "ephemer" abgeleitet wurde. Während das Präfix "epi" u.a. die Bedeutungen "darauf, während, bis zu" umfasst, bedeutet "hemära" nicht nur "Tag", sondern auch "Zeit" und "Leben". Das Ephemere spricht existenziell die Daseinsweise des Menschen an. Ephemeroi, Menschen, sind "Eintagswesen", "eines Schattens Traum". Ohne das Ephemere als Kennzeichen der Moderne und Postmoderne zu vernachlässigen, unter Berücksichtigung der Wechselwirkungen mit Medienumbrüchen und Künsten stehen Fragen nach der (...)

GY, an extensively studied human hemianope, is aware of salient visual events in his cortically blind field but does not call this ''vision.'' To learn whether he has low-level conscious visual sensations or whether instead he has gained conscious knowledge about, or access to, visual information that does not produce a conscious phenomenal sensation, we attempted to image process a stimulus s presented to the impaired field so that when the transformed stimulus T(s) was presented to the normal hemifield it (...) would cause a sensation similar to that caused by s in the impaired field. While degradation of contrast, spatio-temporal filtering, contrast reversal, and addition of smear and random blobs all failed to match the response to a flashed bar sf, moving textures of low contrast were accepted to match the response to a moving contrast-defined bar, sm. Orientation and motion direction discrimination of the perceptually matched stimuli [sm and T(sm)] was closely similar. We suggest that the existence of a satisfactory match indicates that GY has phenomenal vision. (shrink)
