The pathogenic microbe came to be a widely acknowledged “scientific fact” by the end of the 19th century. Taking the transfer of bacteriological knowledge to Warsaw as an example, this article contributes to understanding the question of how knowledge of bacteria was stabilized outside of its original place of production. Conceiving bacteriological knowledge as a laboratory practice it describes the techniques of mobilizing the “laboratory network” this practice depended on. The case of the Polish medical student Odo Bujwid transporting Robert (...) Koch’s and Louis Pasteur’s laboratory networks to Warsaw will be analyzed. Bujwid used literary and visual inscriptions to make these laboratory networks immutably mobile in Bruno Latour’s sense. But he also had to transport three-dimensional objects central to the networks’ functioning back to Warsaw. Personal exchange was, furthermore, essential to their successful transportation to the Polish kingdom. Next to Bujwid’s efforts to transform the laboratory networks into immutable mobiles, the analysis will extend the focus to mutable mobiles as well and will thus show that the successful stabilization of bacteriological knowledge in Warsaw was due not only to the immutability of its laboratory network but to its flexibility and elasticity as well.

ArgumentThe paper argues that epidemic surveillance and state-building were closely interconnected in interwar Poland. Starting from the paper technology of weekly epidemiological reporting it discusses how the reporting scheme of Polish epidemics came into being in the context of a typhus epidemic in 1919–20. It then shows how the statistics regarding nation-wide epidemics was put into practice. It is only when we take into account these practices that we can understand the epidemiological order the statistics produced. The preprinted weekly report (...) form registered Jews and Christians separately. Yet, the imagined national epidemiological space that emerged from it hardly took notice of this separation. Rather, the category that differentiated Polish epidemiological space in medical discourse was the capacity of contributing to the state-making practices of epidemic surveillance. This category divided Poland into two regions: a civilized and modern western region and a backward and peripheral eastern region. (shrink)

As the pre-eminent Enlightenment philosopher, Kant famously calls on all humans to make up their own minds, independently from the constraints imposed on them by others. Kant's focus, however, is on universal human reason, and he tells us little about what makes us individual persons. In this book, Katharina T. Kraus explores Kant's distinctive account of psychological personhood by unfolding how, according to Kant, we come to know ourselves as such persons. Drawing on Kant's Critical works and on his (...) Lectures and Reflections, Kraus develops the first textually comprehensive and systematically coherent account of our capacity for what Kant calls 'inner experience'. The novel view of self-knowledge and self-formation in Kant that she offers addresses present-day issues in philosophy of mind and will be relevant for contemporary philosophical debates. It will be of interest to scholars of the history of philosophy, as well as of philosophy of mind and psychology. (shrink)

When facing a choice between saving one person and saving many, some people have argued that fairness requires us to decide without aggregating numbers; rather we should decide by coin toss or some form of lottery, or alternatively we should straightforwardly save the greater number but justify this in a non-aggregating contractualist way. This paper expands the debate beyond well-known number cases to previously under-considered probability cases, in which not (only) the numbers of people, but (also) the probabilities of success (...) for saving people vary. It is shown that, in these latter cases, both the coin toss and the lottery lead to what is called an awkward conclusion, which makes probabilities count in a problematic way. Attempts to avoid this conclusion are shown to lead into difficulties as well. Finally, it is shown that while the greater number method cannot be justified on contractualist grounds for probability cases, it may be replaced by another decision method which is so justified. This decision method is extensionally equivalent to maximising expected value and seems to be the least problematic way of dealing with probability cases in a non-aggregating manner. (shrink)

Judith Jarvis Thomson argued that abortion is permissible because no one must sacrifice their rights to bodily autonomy. However, assuming a fetus has full moral personhood, and focusing on when abortion is unjust in particular, we argue that Thomson's view of what we ought to sacrifice to aid others is too impoverished. Instead, we argue that abortion is permissible when pregnancy threatens the ability of the mother, or the child, to live minimally well. After explaining the minimally good life account (...) and its application to abortion, we explain its advantages over alternative views. Finally, we examine arguments concluding that abortion is permissible because fetuses are not persons. We argue that personhood is probably a matter of degree rather than a binary property. Thus, abortion is generally permissible early in pregnancy, but as the fetus gets closer to full personhood, adopting the minimally good life standard is appropriate. (shrink)

We study the algebraic implications of the non-independence property and variants thereof on infinite fields, motivated by the conjecture that all such fields which are neither real closed nor separably closed admit a henselian valuation. Our results mainly focus on Hahn fields and build up on Will Johnson’s “The canonical topology on dp-minimal fields” :1850007, 2018).

Because it is often argued that surrogacy should not be treated as contractual, the question arises in which terms this practice might then be couched. In this article, I argue that a phenomenology of surrogacy centering on the notion of trust provides a description that is illuminating from the moral point of view. My thesis is that surrogacy establishes a complex and extended reproductive unit––the “surrogacy triad” consisting of the surrogate mother, the child, and the intending parents––whose constituents are bound (...) together by mutual trustful commitments. Even though a trust-based approach does not provide an ultimate answer to whether surrogacy should be sanctioned or prohibited, it allows for at least some practical suggestions. In particular, I will argue that, under certain conditions, surrogacy is tenable within familial or other significant relationships, and I will stress the necessity of acknowledging the new relationships and moral commitments that result from this practice.

Developmental psychology currently faces a deep puzzle: most children before 4 years of age fail elicited-response false-belief tasks, but preverbal infants demonstrate spontaneous false-belief understanding. Two main strategies are available: cultural constructivism and early-belief understanding. The latter view assumes that failure at elicited-response false-belief tasks need not reflect the inability to understand false beliefs. The burden of early-belief understanding is to explain why elicited-response false-belief tasks are so challenging for most children under 4 years of age. The goal of this (...) article is to offer a pragmatic framework whose purpose is to discharge this burden. (shrink)

In this paper, we argue that ‘good care’ in residential nursing homes is enacted through different care practices that are either inspired by a ‘professional logic of care’ that aims for justice and non-maleficence in the professional treatment of residents, or by a ‘relational logic of care’, which attends to the relational quality and the meaning of interpersonal connectedness in people’s lives. Rather than favoring one care logic over the other, this paper indicates how important aspects of care are constantly (...) negotiated between different care practices. Based on the intricate everyday negotiations observed during an ethnographic field study at an elderly nursing home in Germany, the paper puts forth the argument that care is always a matter of tinkering with different, sometimes competing ‘goods’. This tinkering process, which unfolds through ‘intuitive deliberation’, ‘situated assessment’ and ‘affective juggling’ is then theorized along the conceptualization of a ‘practical ethics of care’: an ethics which makes no a priori judgments of what may be considered as good or bad care, but instead calls for momentary judgments that are pliable across changing situations.

German medical schools have not yet sufficiently introduced students to the field of good scientific practice. In order to prevent scientific misconduct and to foster scientific integrity, courses on GSP must be an integral part of the curriculum of medical students. Based on a review of the literature, teaching units and materials for two courses on GSP were developed and tested in a pilot course. The pilot course was accompanied by a pre-post evaluation that assessed students’ knowledge and attitudes towards (...) scientific integrity and scientific misconduct. A syllabus was designed that comprised the following six topics: theoretical foundations of GSP; scientific publishing; empirical data; scientific supervision and teamwork; clinical research; personal interests. The comparison pre versus post-intervention yielded statistically significant changes in regard to the participants’ knowledge and attitude toward all forms of scientific misconduct treated in the course. As the majority of participants was not familiar with the fundamental regulations or guidelines of GSP, it seems crucial to train students in actively applying such norms to real-world conflicts. Students’ unfamiliarity with the fundamentals of GSP can be linked to the fact that many students have already experienced forms of scientific misconduct. Thus, GSP syllabi should be closely adjusted to a student’s realm of experience. All in all, courses on GSP can be seen as a potential means to increase the number of young scholars. (shrink)

Feminist argumentation theorists have criticized the Dominant Adversarial Model in argumentation, according to which arguers should take proponent and opponent roles and argue against one another. The model is deficient because it creates disadvantages for feminine gendered persons in a way that causes significant epistemic and practical harms. In this paper, I argue that the problem that these critics have pointed out can be generalized: whenever an arguer is given a role in the argument the associated tasks and norms of (...) which she cannot fulfill, she is liable to suffer morally significant harms. One way to react to this problem is by requiring arguers to set up argument structures and allocate roles so that the argument will be reasons-reflective in as balanced a way as possible. However, I argue that this would create to heavy a burden. Arguers would then habitually have to take on roles that require them to divert time and energy away from the goals that they started arguing for and instead serve the goal of ideal reasons-reflectiveness. At least prima facie arguers should be able to legitimately devote their time and energy towards their own goals. This creates a problem: On the one hand, structures that create morally significant harms for some arguers should be avoided—on the other hand, arguers should be able to take argument-roles that allow them to devote themselves to their own argumentative goals. Fulfilling the second requirement for some arguers will often create the morally significant harms for their interlocutors. There are two possible solutions for this problem: first, arguers might be required to reach free, consensual agreements on the structure they will adopt for their argument and the way they will distribute argumentative roles. I reject this option as both fundamentally unfeasible and practically unrealistic, based on arguments developed by theorists like Krabbe and Jacobs. I argue that instead, we should take a liberal view on argument ethics. Arguers should abide by moral side constraints to their role taking. They should feel free to take roles that will allow them to concentrate on their argumentative goals, but only if this does not create a situation in which their interlocutors are pushed into a role that that they cannot effectively play.

ABSTRACTRumination and worry are two perseverative, negatively valenced thought processes that characterise depressive and anxiety disorders. Despite significant research interest, little is known about the everyday precipitants and consequences of rumination and worry. Using an experience sampling methodology, we examined and compared rumination and worry with respect to their relations to daily events and affective experience. Participants diagnosed with Major Depressive Disorder, Generalized Anxiety Disorder, co-occurring MDD–GAD, or no diagnosis carried an electronic device for one week and reported on rumination, (...) worry, significant events, positive affect, and negative affect. Across the clinical groups, occurrences of everyday events predicted subsequent increases in rumination, but not worry. Further, higher momentary levels of rumination, but not worry, predicted subsequent decreases in PA and increases in NA. Thus, in these clinical groups, rumination was more susceptible to...

Scholars increasingly argue that entrepreneurs and their small- and medium-sized enterprises should play a central role in reducing the rate and magnitude of climate change. However, evidence suggests that while some entrepreneurs recognize their crucial role in addressing climate change, most do not. Why some entrepreneurs nevertheless concern themselves with climate change has largely been overlooked. Some initial work in this area tentatively suggests that these entrepreneurs may engage with climate change because of their personal values, which either focus on (...) financial or socio-ecological reasons, or a combination of both. Yet, it is unclear if all for-profit entrepreneurs engage with climate change for the same reasons, or if indeed their motivations vary across business types. Over a period of four years, we examined entrepreneurs’ motivations to engage with climate change through a variety of qualitative research methods. Our findings illustrate how entrepreneurs who address climate change have motivations specific to their business activity/industry and level of maturity. In each instance, we link these motivations to distinct conceptualizations of time and place. We contend that, through a more differentiated understanding of entrepreneurial motivations, policy-makers can draft climate change-related policies tailored to entrepreneurial needs. Policies could both increase the number of entrepreneurs who already engage in climate change mitigation and leverage the impact of those entrepreneurs already mitigating climate change. (shrink)

BackgroundThe bioethical debates concerning living donation and surrogacy revolve around similar ethical questions and moral concepts. Nevertheless, the ethical discourses in both fields grew largely isolated from each other.MethodsBased on a review of ethical, sociological and anthropological research this paper aims to link the ethical discourses on living kidney donation and surrogacy by providing a comparative analysis of the two practices’ relational dimension with regard to three aspects, i.e. the normative role of relational dynamics, social norms and gender roles, and (...) reciprocity. Based on this analysis, we derive conclusions for the framing of living organ donation and surrogacy in ethical theory and practice.ResultsFirst, our analysis emphasizes the relevance of acknowledging the complex relational implications of living kidney donation and surrogacy. Underestimating this relational dimension may not only lead to individual crises but endanger existing as well as newly emerging familial relationships. Second, we point out differences in the normative assessment of social norms and gender roles in the ethical debates about living kidney donation and surrogacy. In particular, we show how different evaluations of altruism affect the understanding of autonomy in both contexts. In addition, we sensitize for biased perceptions of gender roles. Finally, we argue that challenges resulting from unresolved reciprocity are an issue in living kidney donation and surrogacy independent of whether the exchange of body parts or bodily services is framed as a gift or commercial exchange. By pointing out the limits of financial compensation, we stress the relevance of non-material, relational rewards as potential remedy. (shrink)

Realists and non-ideal theorists currently criticise Rawlsian mainstream liberalism for its inability to address injustice and political conflict, as a result of the subordination of political philosophy to moral theory, as well as an idealising and abstract methodology. Seeing that liberalism emerged as a theory for the protection of the individual from conflict and injustice, these criticisms aim at the very core of liberalism as a theory of the political and therefore deserve close analysis. I will defend Judith N. Shklar’s (...) liberalism of fear as an answer to these challenges. I will argue that the liberalism of fear maintains realism’s conflictual and inherently political thrust while also integrating a perspective on injustice. I will defend the claim that in contrast to the two aforementioned criticisms, the liberalism of fear develops its own normative standard from which political arrangements can be assessed. It does so by replacing the idealising approach to political philosophy with a non-utopian methodology, which opens a negative perspective on what is to be avoided in the political sphere, and how to detect and deal with injustice. Due to this standard, it is a liberal theory that is uniquely able to meet the realist and non-ideal challenge. (shrink)

When evaluating the arguer instead of the argument, we soon find ourselves confronted with a puzzling situation: what seems to be a virtue in one argumentative situation could very well be called a vice in another. This paper will present the idea that there are in fact two sets of virtues an arguer has to master—and with them four sometimes very different roles.

Ein gelungenes Arzt-Patient-Verhältnis, das auf gegenseitigem Vertrauen und ärztlicher Verantwortung basiert, ist ein zentraler Bestandteil des Ideals der ärztlichen Profession. Aktuell wird vielfach von einem neuen „ökonomischen Paradigma“ in der Medizin gesprochen, das dieses Verhältnis vermeintlich unterminiert. Als ein wichtiges Merkmal dieses Paradigmas gilt das Verständnis vom Patienten als Kunden, der charakterisiert ist durch seine Selbstbestimmung bzw. Autonomie. Wie stellt sich die Kundenrolle nun aber bei vulnerablen Patientengruppen dar, die in ihrer Autonomie eingeschränkt sind, und was bedeutet dies wiederum für (...) das Arzt-Patient-Verhältnis? In dem vorliegenden Artikel wollen wir deshalb die Fragestellung verfolgen, ob sich ärztliche Verantwortung bzw. das Arzt-Patient-Verhältnis ändert, wenn sich der (vulnerable) Patient als Kunde begreift. Als Analysesetting dient die Palliativmedizin, da sie als Beispiel für eine besonders vulnerable Patientengruppe gelten kann. Als Basis der Argumentation werden die Ergebnisse einer qualitativen Studie herangezogen, welche die Einstellungen von Palliativpatienten zum Thema „der Patient als Kunde“ erhob sowie der Frage nachging, ob sich Palliativpatienten, speziell im Rahmen von medizinischen Entscheidungen, als selbstbestimmt begreifen. Die Studienergebnisse zeigen, dass Autonomie relational verstanden werden muss und dem Arzt eine entscheidende Rolle in der Ermöglichung von Patientenselbstbestimmung zukommt – ganz unabhängig von der Selbstattribuierung der Befragten als Kunde oder Patient. Anschließend werden diese Ergebnisse dahingehend analysiert, ob sie als Ausdruck einer Veränderung des Arzt-Patient-Verhältnisses und der ärztlichen Verantwortung gegenüber den Patienten zu werten sind. Hieraus folgernd wird nach den praktischen Implikationen für das Arzt-Patient-Verhältnis auf der Grundlage der „Ethics of Care“ gefragt sowie auf die individuelle Betreuungsnotwendigkeit, speziell von vulnerablen Patientengruppen, verwiesen.

In educational hypermedia environments, students are often confronted with potential sources of distraction arising from additional information that, albeit interesting, is unrelated to their current task goal. The paper investigates the conditions under which distraction occurs and hampers performance. Based on theories of volitional action control it was hypothesized that interesting information, especially if related to a pending goal, would interfere with task performance only when working on easy, but not on difficult tasks. In Experiment 1, 66 students learned about (...) probability theory using worked examples and solved corresponding test problems, whose task difficulty was manipulated. As a second factor, the presence of interesting information unrelated to the primary task was varied. Results showed that students solved more easy than difficult probability problems correctly. However, the presence of interesting, but task-irrelevant information did not interfere with performance. In Experiment 2, 68 students again engaged in example-based learning and problem solving in the presence of task-irrelevant information. Problem-solving difficulty was varied as a first factor. Additionally, the presence of a pending goal related to the task-irrelevant information was manipulated. As expected, problem-solving performance declined when a pending goal was present during working on easy problems, whereas no interference was observed for difficult problems. Moreover, the presence of a pending goal reduced the time on task-relevant information and increased the time on task-irrelevant information while working on easy tasks. However, as revealed by mediation analyses these changes in overt information processing behavior did not explain the decline in problem-solving performance. As an alternative explanation it is suggested that goal conflicts resulting from pending goals claim cognitive resources, which are then no longer available for learning and problem solving.

Both aggressive and non-aggressive strategies of competition pervade the poetics of the “Iliad”, the “Odyssey”, and the “Argonautica”, shaping the expression of narrator-ethos and implicit standards of poetic quality. Studying a poetics of competition in scenes of conjugal bedroom conversation in Il. 3.421-448, Od. 23.295-343, and A. R. 4.1068-1111 benefits understanding of the text-immanent strategies employed to achieve and advertise the superior quality of these poems. The poetics of competition in Il. 3.421-448 can be read against Middle-Eastern poetry and the (...) Epic Cycle, that of Od. 23.295-343 against the Iliad and perhaps lost Nostoi-traditions, while A. R. 4.1068-1111 engages not just the Odyssey, but also Herodotus 3.134 f., the “Dios apate” in Il. 14, and Peripatetic and Alexandrian scholarship. (shrink)

Background: The vascular depression hypothesis emphasizes the significance of vascular lesions in late-life depression. At present, no meta-analytic model has investigated whether a difference in hyperintensity burden compared to controls between late-life and late-onset depression is evident. By including a substantial number of studies, focusing on a meaningful outcome measure, and considering several moderating and control variables, the present meta-analysis investigates the severity of hyperintensity burden in major depressive disorder (MDD) and bipolar disorder (BD). A major focus of the present (...) meta-analysis refers to the role of age at illness onset. It is analyzed whether late-onset rather than late-life depression characterizes vascular depression. Method: In total, 68 studies were included in the meta-analysis and a multilevel random effects model was calculated using Hedges’ g as the effect size measure. Results: The severity of hyperintensity burden was significantly greater in the patient group compared to the control group. This effect was evident regarding the whole patient group (g = 0.229) as well as both depression subgroups, with a significantly greater effect in BD (g = 0.374) compared to MDD (g = 0.189). Hyperintensity burden was more pronounced in late-onset depression than in early-onset depression or late-life depression. A considerable heterogeneity between the included studies was observed, which is reflected by the large variability in effects sizes. Conclusion: In conclusion, the present meta-analysis underscores the association of hyperintensities with MDD and BD. Especially late-onset depression is associated with an increased hyperintensity burden, which is in line with the vascular depression hypothesis. The results suggest that it might be more feasible to confine the concept of vascular depression specifically to late-onset depression as opposed to late-life depression. Further research is needed to understand the causal mechanisms that might underlie the relation between hyperintensity burden and depression. (shrink)

Usually, rhetoric is supposed to provide a model of law which describes legal interactions as volitive, arbitrary, and void of any system. However, the Mainz School, founded by Theodor Viehweg, proves the contrary: without referring to any metaphysics, such as consensus or auditoire universel, it seeks to discover the systematic character and the more or less flexible structures of legal rhetoric.

The passage of time influences the content of the law and therefore also the validity of legal arguments. This is true even for charter-arguments, despite the widely held view that constitutional law is made to last. In this paper, I investigate the reason why the sanctity-of life argument against physician assisted suicide lost its validity between the Supreme Court decision in Rodriguez v. British Columbia in 1993 and Carter v. Canada in 2015. I suggest that a rhetorical approach to argument (...) evaluation is the best basis for a satisfying explanation. (shrink)

Dieser Beitrag nimmt drei Perspektiven ein. Zunächst geht es um Ikonografien der Fliege und des Totenkopfes innerhalb der Stilllebenmalerei seit der Frühen Neuzeit und um die doppelte Vergänglichkeitsmetaphorik, die aus der Kombination von Motiv und Genre resultiert. Zudem geht die Untersuchung der Frage nach, welche medialen und semantischen Verschiebungen bei dem Übertrag dieser dichten Vanitas-Konfiguration in die Fotografie entstehen. Mein Fokus liegt dabei auf den zeitgenössischen Arbeiten der amerikanischen Fotografin Paulette Tavormina und ihren zwischen 2013 und 2015 entstandenen Re-Inszenierungen historischer (...) Stillleben-Darstellungen. Aus der motiv- und gattungsspezifischen sowie der medialen Perspektive ergeben sich schließlich Fragestellungen, die das Thema Vanitas in seiner moralisierenden wie auch zeitlichen Dimension thematisieren. So stelle ich zwei konträre Formen der Temporalität in den Stillleben mit Fliege und Totenkopf zur Diskussion: das Enden und das Sich-Verflüchtigen. (shrink)

Gaslighting is a form of manipulation that undermines a target’s confidence in their own cognitive faculties. Different forms of gaslighting can be distinguished according to whether they undermine a target’s confidence in their emotional reactions, perceptions, memory, or reasoning abilities. I focus on ‘emotional gaslighting’, which undermines a target’s confidence in their emotional reactions and corresponding evaluative judgments. While emotional gaslighting rarely occurs in isolation, it is often an important part of an overall gaslighting strategy. This is because emotions can (...) help us to understand the evaluative aspects of our situation and thus put us in a position to protest wrongs, which is a context in which gaslighting frequently occurs. I argue that affective empathy constitutes an important antidote to emotional gaslighting. Affective empathy can lead to endorsement of a target’s emotional reaction as appropriate to their situation and agreement with the corresponding evaluative judgment. When it leads to endorsement, affective empathy can counteract the effects of emotional gaslighting because it reassures a target in their ability to make evaluative judgments based on their emotional reactions. Because of its opposing effects, affective empathy with the victim thus constitutes an important intervention to emotional gaslighting on the part of third parties. (shrink)

This article sets out to describe and solve two puzzles that emerge in segregated labour markets (e.g. the USA or Sweden). First, in many hiring contexts people profess to adhere to egalitarian norms, and specifically to a qualification norm according to which job qualification should be the basis of employment. Still there is evidence of frequent norm violations (discrimination). Surprisingly, the norm persists and people do not frequently protest against such norm violations. The second puzzle is that people are suspicious (...) of the hiring of minorities, perceiving such hirings as evidence that a ‘political correctness’ norm has replaced the qualification norm. The article proposes that both puzzles can be solved within a game-theoretical model of social norm-following, where implicit bias is introduced into an ‘employment game’. Within this model, implicit bias plays a double role. First, it interferes with employers' hiring decisions regarding ethnic majority and minority members, respectively. This is the standard way of understanding the effects of implicit bias. Second, implicit bias interferes with bystander evaluations of hired candidates' qualifications. This is a hitherto overlooked effect of implicit bias. The article concludes that once we understand the double role of implicit bias, the two puzzles are resolved. (shrink)

Inspired by interviews conducted with scientists who primarily use participatory research forms, the article develops the concept of epistemic caring as a proposal for a participatory research practice that is sensitive for epistemological difference and the associated consequences. Based on the observation that participatory research has so far hardly been able to produce an equal co-constitution of knowledge, the article points out epistemological pitfalls that exist in it and analyses two specific concepts as examples of the risk of problematic epistemological (...) and hegemonic tendencies sneaking into this kind of research practice with harmful consequences for the non-academic participants, that is: empowerment and participation/co-production. Following the recent debate on care in the Environmental Humanities and Karen Barad’s methodological thoughts on diffraction, the article reconceptualizes participatory research as a matter of care consisting of multiple care relations in order to be able to grasp the complex epistemic entaglements and intra-dependencies contained within it. Conceiving these relationships between academic and non-academic participants as an ecology of care themself helps to understand that they are fundamentally precarious and transformative and thus inherently ethical.
