We investigate to what extent theorems about quantum mechanical or classical entropy can be generalized to functionals of the type ρ→Tr f(ρ), or ψ→∫f(ψ)dμ, respectively, wheref is an arbitrary concave function.

Evidence is accumulating that individual and environmental factors in childhood and adolescence should be considered when investigating adult health and aging-related processes. The data required for this is gathered by comprehensive long-term longitudinal studies. This article describes the protocol of the Zurich Longitudinal Studies, a set of three comprehensive cohort studies on child growth, health, and development that are currently expanding into adulthood. Between 1954 and 1961, 445 healthy infants were enrolled in the first ZLS cohort. Their physical, motor, cognitive, (...) and social development and their environment were assessed comprehensively across childhood, adolescence, and into young adulthood. In the 1970s, two further cohorts were added to the ZLS and assessed with largely matched study protocols: Between 1974 and 1979, the second ZLS cohort included 265 infants, and between 1970 and 2002, the third ZLS cohort included 327 children of participants of the first ZLS cohort. Since 2019, the participants of the three ZLS cohorts have been traced and invited to participate in a first wave of assessments in adulthood to investigate their current health and development. This article describes the ZLS study protocol and discusses opportunities, methodological and conceptual challenges, and limitations arising from a long-term longitudinal cohort recruited from a study about development in early life. In the future, the ZLS will provide data to investigate childhood antecedents of adult health outcomes and, ultimately, will help respond to the frequent call of scientists to shift the focus of aging research into the first decades of life and, thus, to take a lifespan perspective on aging.

How different neural crest derivatives differentiate in distinct embryonic locations in the vertebrate embryo is an intriguing issue. Many attempts have been made to understand the underlying mechanism of specific pathway choices made by migrating neural crest cells. In this speculative review we suggest a new mechanism for the regulation of neural crest cell migration patterns in avian and mammalian embryos, based on recent progress in understanding the expression and activity of receptor tyrosine kinases during embryogenesis. Distinct subpopulations of crest‐derived (...) cells express specific receptor tyrosine kinases while residing in a migration staging area. We postulate that the differential expression of receptor tyrosine kinases by specific subpopulations of neural crest cells allows them to respond to localized growth factor ligand activity in the embryo. Thus, the migration pathway taken by neural crest subpopulations is determined by their receptor tyrosine kinase response to the differential localization of their cognate ligand. (shrink)

Attention is a complex process that modulates perception in various ways. Phenomenological philosophy provides an array of concepts for describing the rich structures of attention, thereby avoiding reductions to singular aspects of an experiential spectrum. By suggesting various modes and levels of attentional experience, we intend to do some justice to its complexity, taking into account sub-personal and personal factors on the side of subjective horizons and feature-oriented as well as context-oriented aspects on the side of objective horizons.

The body is both the subject and object of intentionality: qua Leib, it experiences worldly things and qua Körper, it is experienced as a thing in the world. This phenomenological differentiation forms the basis for Helmuth Plessner’s anthropological theory of the mediated or eccentric nature of human embodiment, that is, simultaneously we both are a body and have a body. Here, I want to focus on the extent to which this double aspect of embodiment relates to our experience of temporality. (...) Indeed, to question, does this double bodily relation correspond to a twofoldtemporality of embodied intentionality? In the first part of this paper, I differentiate between the intentional temporality of being a body and the temporal experience of having a body. To further my argument, in the second part, I present examples of specific pathologies, as well as liminal cases of bodily experiences, wherein these temporal dimensions, which otherwise go hand-in-hand, become dissociated. Phenomenologically, I want to argue that Husserl’s differentiation between Leib and Körper corresponds to two genetic forms of intentionality – operative and act intentionality – and that these are, in turn, characterized by different temporalities. Anthropologically, I want to argue that having a body – what occurs as an inherent break to human embodiment – is the presupposition for the experience of a stable and object-like time. I will conclude that the double aspect of human embodiment and in particular the thematic experience of having a body enables both the experience of a past, which is remembered, and a future that is planned.

The human body can be regarded in at least two ways: objectively, as a physical and organic body; and subjectively, as the center of orientation and lived affective unity. However, this distinction can lose sight of the fact that the ‘lived body’ is not reducible to subjective idiosyncrasies. Trans-individual norms are embodied too, as Michel Foucault and Judith Butler have shown. Phenomenological investigations of normalization and habitualization help bring these two important dimensions of embodiment together and overcome simplistic oppositions between (...) phenomenological and poststructuralist approaches. These investigations lead into issues of female body optimization and control that we take to be characteristic of contemporary neoliberalist embodiment. (shrink)

ABSTRACTIn Foucault's later works, experience and embodiment become important for explaining the normative constitution of the subject: for norms to be effective, discourses are insufficient – they must be experienced and embodied. Practices of “discipline” inscribe power constellations and discourses into subjective experience and bodies. In his lectures on the Hermeneutics of the Subject, he turns this “violent” form of normative embodiment into an ethical perspective by referring to the Stoic tradition. Even though Foucault never developed a notion of experience (...) and embodiment himself, his ideas can be re-read and complemented from a phenomenological perspective.The article tries to investigate the role of bodily experience and practice in Foucault's Genealogy and to bring it into dialogue with Husserl and Merleau-Ponty's conceptions of the lived body. It will attempt to show that concepts like sedimentation and habituality can help to explain how cultural norms not only influence the way we think abou.. (shrink)

Husserl seldom refers to feelings, and when he does, he mainly focuses on their axiological character, which corresponds to a specific kind of value apprehension. This paper aims to discuss the role of feelings in Husserl from a different angle. For this purpose it makes a detour through Husserl’s early account of attention. In a text from 1898 on attention the aspect of interest, which is said to have a basis in feeling, plays an essential role. Although Husserl argues here (...) that every specific interest is dependent on an objectifying act of perception, he at the same time states that every act of perception necessarily has to be accompanied by an interest of some sort. In the latter sense, the genuine motivational force and necessity of this feeling aspect, namely interest, is emphasized. This ambiguity – or even contradiction – shall be the point of departure for the following considerations. The paper argues that it is possible to interpret the role of feelings in intentionality in a different way, namely not as an effect of current perception but as a cause of further perceptions. This tendency is first indicated in the text from 1898 and elaborated further in Husserl’s genetic approach in Experience and Judgment. In Experience and Judgment Husserl develops a broader notion of interest, defining it as a general perceptual drive. This general drive – so the paper will argue – expresses itself in concrete perception as a specific preference: it discloses or makes manifest what is relevant for an individual subject at a given time.

In this paper, I show that a phenomenological concept of normality can be helpful to understand the experiential side of post-truth phenomena. How is one’s longing for, or sense of, normality related to what we deem as real, true, or objective? And to what extent is the sense for “what (really) is” related to our beliefs of what should be? To investigate this, I combine a phenomenological approach to lived normality with a genealogical account of represented normality that sheds light (...) on the social and historical contingency of definitions of normality and their intertwinement with structures of power. It is my contention that such an approach to normality is well-suited to investigate how is and ought are interrelated within subjective experience and practice. This might in turn help overcoming one-sided debates on post-truth, which rely on the strict opposition of objectivity versus subjectivity, universal truth versus subjective experience, facticity versus meaning, or reason versus stupidity. It also sheds light on the ambivalent or contested status of experience within debates of post-truth and feminist theory. I will conclude that post-truth is related to what Hannah Arendt has termed the lack of a common world (i.e., normality), arguing that a plurality of experiences is needed to let the “real world” stand its ground again.

This volume proposes an interdisciplinary framework that views attention from a particular angle: as a means of accessing, that is, disclosing the world in a practical and meaningful way. Moreover, it investigates how this access is concretely mediated. The book is structured in the following two parts: 1) Attention and Access The first section is concerned with attention as such. What is attention and what does it do? A common thread between the expected contributions addresses attention as a directional disclosing (...) process, opening up a possibility of access to the world. This section brings contributions from a cognitive psychology/neuroscience into dialogue with phenomenology and philosophy of mind; and links attention research to new paradigms, such as predictive coding, and 4e cognition. 2) Attention and Mediation The second section tackles the question of how this disclosing process may work. Concrete disclosing is always framed by different factors and frames the world. The contributions in this section spell out the different ways in which attention is mediated and shaped by technology, situations, sociality etc., and the ways in which attention mediates our access to the world.

Employment is critical for refugees’ positive integration into a receiving country. Enabling employment requires cross-sector collaborations, that is, employers collaborating with different stakeholders such as refugees, local employees, other employers, unofficial/official supporters, and authorities. A vital element of cross-sector collaborations is trust, yet the complexity of cross-sector collaborations may challenge the formation and maintenance of trust. Following a theory elaboration approach, this qualitative study with 37 employers and 27 support workers in Germany explores how employers’ experiences in cross-sector collaborations on (...) refugees’ labor market integration affect their trust in other stakeholders in this cross-sector space. Specifically, we explored employers’ perceptions of trust breaches, and how these perceptions affect their further engagement in cross-sector collaborations on refugee integration. Based on our findings, we propose a process model that describes how unmet collaboration expectations and negative assessments of collaborators’ attitudes and behaviors lead to perceived trust breaches which, in turn, lead to employers’ hesitancy to hire refugees and/or to engage in cross-sector collaborations. In doing so, we extend existing theory on trust within organizations to the cross-sector context of refugee integration, uncovering context-specific meanings to trustworthiness dimensions and illustrating how breaches of different trustworthiness dimensions can interact. Moreover, we show how social policies, resources, and trustors’ perceived vulnerability in collaborations shape their risk perceptions. This study highlights the central role of trust for refugee integration and illustrates how missing goals and process clarity endanger sustainable collaborations. (shrink)

Phenomenologically speaking, one can consider the experiencing body as normative insofar as it generates norms through repeated actions and interactions, crystallizing into habits. On the other hand according to Foucauldian approaches, the subjective body does not generate norms but is itself produced by norms: Dominant social norms are incorporated via repeated practices of discipline. How is the individual level of habit formation in phenomenology related to this embodiment of supra-individual norms? In what sense can we differentiate between a habit formation (...) that results in a skill and one that disciplines a body? To address these questions the paper will analyze examples of the embodiment of norms in Foucault and feminist philosophy and show how they rely on the phenomenological concept of the actual and habitual body.

This paper will interpret Judith Butler’s theory of performativity and materialization as a theory of identity, and so put it into dialogue with a phenomenological account of habit formation. The goal is to argue that identity is developed already at a bodily level and that this takes place via the processes of habit formation. The constitution of subjectivity, in other words, requires at the most basic level some kind of bodily performativity. What follows intends to draw out the concept of (...) ‘the body’ in Butler’s work, the role of which is surprisingly meagre given her clear favour of language signification in the elaboration of her theory of performativity. Alternatively, this paper will provide a phenomenology of habit formation that re-introduces the body not as thematic materiality, but as lived materiality. The body will therefore be conceived as something which is already skilful and creative, sensitive and vulnerable, and ultimately, as Butler anticipates, responsive to the intertwinement of individual and social aspects of identity formation. In this regard, I will argue for a performative theory of (bodily) habitual identity. (shrink)

In this radical reinterpretation of Aristotle's Metaphysics, Walter E. Wehrle demonstrates that developmental theories of Aristotle are based on a faulty assumption: that the fifth chapter of Categories is an early theory of metaphysics that Aristotle later abandoned.

In this paper, I will investigate the potential of what I term Merleau-Ponty’s ‘situated phenomenology’ for an investigation of normality from within and from without. First, I will argue that the concept of situation in the Phenomenology of Perception demarcates Merleau-Ponty’s turn from a mere epistemological to a concrete critical phenomenology. Second, I will apply Merleau-Ponty’s concept of situation as being situated and as being in situation to an investigation of normality. In doing so, I endeavor to differentiate between lived (...) and represented normality, a difference which in turn corresponds to an operative and established normativity. A situated account of normality thereby combines a phenomenological and a genealogical perspective. My aim is to provide a toolkit to investigate the intertwinement of represented and lived normality, that is, of being situated and being in situation. (shrink)

From a historico-cultural point of view the notion of normativity is closely tied to the apparently descriptive category of normality. This relation seems even tighter on the level of experience. As Husserl shows that normality, in the form of concordance and optimality, is a constitutive feature of experience itself. But in what sense can we speak of normativity in the realm of experience? Husserl himself saw no need to pose this question. But to explain the possibility of normal and coherent (...) perception one needs more than merely formal criteria (like concordance and its adjustment to an optimum): one must also take into account the attentional nature of perception. In this regard, the present paper will consider Husserl’s early treatment of attention and integrate it with its genetic implications on the level of affection. Doing so shows that subjective experience is characterized by a preference- structure, motivated by the embodied subject’s individual and cultural horizons of interest. It is this that allows one to speak of a precursor to normativity in the realm of experience. Moreover it can be argued that interest not only influences perception from the lowest level, but can be seen as a precondition for any current attention. Thus to speak of normativity in experience in this stronger sense, means not only that perception already contains traces of intersubjective norms; it also means that such norms determine what you can see at all. --------------------------------------------------------------------------Aus kulturgeschichtlicher Perspektive steht der Begriff Normativität in einer engen Verbindung mit der vermeintlich deskriptiven Kategorie der Normalität. Erweist sich diese Relation aber bereits auf der Ebene der sinnlichen Erfahrung als grundlegend, hat dies weitreichende Konsequenzen. Wie Husserl zeigt, ist Normalität im Sinne der formalen Kriterien von Einstimmigkeit und Optimalität selbst konstitutiv für jede Erfahrung. Um darüber hinaus die Normativität innerhalb der Erfahrung in den Blick zu bekommen, soll in diesem Beitrag die phänomenologische Beschreibung um einen wichtigen Aspekt ergänzt werden: die Aufmerksamkeit. Zu den formalen Normalitätskriterien muss eine konkrete subjektive Präferenz hinzu treten, die eine Differenzierung der Wahrnehmungsinhalte leistet. Anders lässt sich eine normale und kohärente Erfahrung nicht hinreichend erklären. Husserls frühe Arbeiten zur Aufmerksamkeit und Intentionalität sollen daher mit späteren genetischen Analysen zu einer umfassenderen Konzeption von Aufmerksamkeit verbunden werden. Hierbei wird deutlich, dass jede subjektive Erfahrung durch ihre präferenzielle Struktur charakterisiert ist, die sowohl von individuellen als auch kulturellen Interessenshorizonten des leiblichen Subjekts motiviert ist. Dies erlaubt es, von einer rudimentären Form der Normativität innerhalb der Erfahrung zu sprechen. Diese immer schon intersubjektiven Interessensdimensionen beeinflussen weiterhin jedes Aufmerksamkeitsverhalten von den untersten Stufen der Wahrnehmung bis hin zu höheren Geistesakten. Normativität in einem starken Sinne meint damit nicht nur, dass sich die Spuren intersubjektiver Normen bereits innerhalb der Wahrnehmung finden lassen. Vielmehr bestimmen diese Normen, was wir im Einzelfall überhaupt sehen können. (shrink)

This volume explores the role and status of phenomena such as feelings, values, willing, and action in the domain of perception and (social) cognition, as well as the way in which they are related. In its exploration, the book takes Husserl's lifelong project Studien zur Struktur des Bewusstseins (1909-1930) as its point of departure, and investigates these phenomena with Husserl but also beyond Husserl. Divided into two parts, the volume brings together essays that address the topics from different phenomenological, philosophical, (...) and psychological perspectives. They discuss Husserl's position in dialogue with historical and recent philosophical and psychological debates and develop phenomenological accounts and descriptions with the help of Geiger, Heidegger, Merleau-Ponty, Plessner, Sartre, Scheler, Schopenhauer, and Reinach.

In this letter to our German colleagues we describe the situation, mentality, and organization of academic philosophy in the Netherlands in comparison to Germany. We proceed in five acts. In the first act, A wide beach, we set the stage and introduce the two academic landscapes; in the second act, Between controversy and frontal teaching, we compare the Dutch and German academic temper and practices. In the third act, Flat land, flat hierarchies, we parallelize the geography of the Netherlands and (...) the organizational structure of Dutch universities. In the fourth act, Philosophers among merchants, we discuss the positive and negative sides of the liberal, transparent, competitive and progress-oriented spirit of Dutch academic philosophy. In the fifth and final act, Philosophy from the pragmatic point of view, we conclude what we can learn from our Dutch neighbours: We plea for a non-elitist, down to earth, straight-forward, and open-minded way of doing philosophy, where one is neither shying away from controversy nor too shy to come down from the ivory tower and mingle with the audience.

Le phénomène de l’attention ne fut investi par la science qu’au début du xxe siècle. Dans la phénoménologie et la psychologie de l’époque, il est caractérisé à l’unisson comme un « phare de la perception » jetant une lumière particulièrement vivifiante et clarifiante sur les choses simplement perçues. Ce n’est qu’avec l’émergence de la psychologie comme science purement empirique que les deux disciplines ont commencé, chacune de son côté, à thématiser le phénomène de l’attention. Nous voudrio...

A growing volume of research from global data demonstrates that institutional care under conditions of deprivation is profoundly damaging to children, particularly during the critical early years of development. However, how these individuals develop over a life course remains unclear. This study uses data from a survey on the health and development of 420 children mostly under the age of three, placed in 12 infant care institutions between 1958 and 1961 in Zurich, Switzerland. The children exhibited significant delays in cognitive, (...) social, and motor development in the first years of life. Moreover, a follow-up of a subsample of 143 children about 10 years later revealed persistent difficulties, including depression, school related-problems, and stereotypies. Between 2019 and 2021, these formerly institutionalized study participants were located through the Swiss population registry and invited to participate once again in the research project. Now in their early sixties, they are studied for their health, further development, and life-course trajectories. A mixed-methods approach using questionnaires, neuropsychological assessments, and narrative biographical interviews was implemented by a multidisciplinary team. Combining prospective and retrospective data with standardized quantitative and biographical qualitative data allows a rich reconstruction of life histories. The availability of a community sample from the same geographic location, the 1954–1961 cohort of the Zurich Longitudinal Studies, described in detail in a paper in this issue, enables comparison with an unaffected cohort. This article describes the study design and study participants in detail and discusses the potential and limitations of a comparison with a community sample. It outlines a set of challenges and solutions encountered in the process of a lifespan longitudinal study from early childhood into the cusp of old age with a potentially vulnerable sample and summarizes the lessons learned along the way.

Legal analysis of survey responses and existing laws identified several potential state legal barriers to a POLST Paradigm implementation. The most potentially problematic barriers are detailed statutory specifications for out-of-hospital DNR protocols. Other potential barriers include limitations on the authority to consent to forgo life-sustaining treatments, medical preconditions, and witnessing requirements for out-of-hospital DNR protocols.

Dieses Handbuch gibt einen umfassenden Überblick über das Gesamtwerk Husserls und seinen Einfluss auf die nachfolgende Philosophie und andere Wissenschaften. Es ist gleichzeitig das erste Referenzwerk, was nicht nur Husserls veröffentlichte Schriften, sondern auch die Themen des zur Husserls Lebzeiten unveröffentlichten Nachlasses berücksichtigt.​Edmund Husserl gilt als der Begründer der Phänomenologie und als einer der wichtigsten Philosophen des 20. Jahrhunderts. Er stand jedoch lange im Schatten seiner Nachfolger wie etwa Martin Heidegger oder Jean-Paul Sartre. Etwa ab den 1990er Jahren setzte eine (...) Wendung ein, da nun Husserls unveröffentlichter Nachlass zunehmend rezipiert wird. Dabei wird deutlich, dass Husserl mit seiner Phänomenologie für die Philosophie wichtiges Neuland erschlossen sowie zu vielen traditionellen Themen der Philosophie wichtige Beiträge geleistet hat. Seine feingliedrigen Beschreibungen und Strukturbestimmungen der Erfahrung und des Bewusstseins hatten darüber hinaus bedeutende Einflüsse auf Disziplinen, wie etwa Psychologie, Anthropologie oder Soziologie.

Jeder scheint zu wissen, was Aufmerksamkeit ist: Sie ermöglicht uns die Konzentration auf Wichtiges und damit zugleich das Ignorieren von Unwichtigem. Sieht man jedoch genauer hin, ist es nicht ganz so eindeutig, was Aufmerksamkeit ist. Es reicht nicht, Aufmerksamkeit auf den aktuellen Akt, Gegenstand oder die jeweils messbare Verhaltensleistung zu reduzieren, wie dies in Philosophie und empirischer Psychologie oft der Fall ist. Um das Phänomen Aufmerksamkeit in seiner Dynamik zu beschreiben, muss man die Horizonte der Aufmerksamkeit thematisieren. Nicht nur die (...) gegenständlichen Horizonte, sondern vor allem die subjektiven Horizonte: die zeitliche, leibliche und habituelle Dimension der Aufmerksamkeit. (shrink)
