Tolerance for blood transfusion risks is very low, as evidenced by the implementation of expensive blood tests and the rejection of gay men as blood donors. Is this low risk tolerance supported by the precautionary principle, as defenders of such policies claim? We discuss three constraints on applying the precautionary principle and show that respecting these implies tolerating certain risks. Consistency means that the precautionary principle cannot prescribe precautions that it must simultaneously forbid taking, considering the harms they might cause. (...) Avoiding counterproductivity requires rejecting precautions that cause more harm than they prevent. Proportionality forbids taking precautions that are more harmful than adequate alternatives. When applying these constraints, we argue, attention should not be restricted to harms that are human caused or that affect human health or the environment. Tolerating transfusion risks can be justified if available precautions have serious side effects, such as high social or economic costs. (shrink)

For simplicity, most of the literature introduces the concept of definitional equivalence only for disjoint languages. In a recent paper, Barrett and Halvorson introduce a straightforward generalization to non-disjoint languages and they show that their generalization is not equivalent to intertranslatability in general. In this paper, we show that their generalization is not transitive and hence it is not an equivalence relation. Then we introduce another formalization of definitional equivalence due to Andréka and Németi which is equivalent to the Barrett–Halvorson (...) generalization in the case of disjoint languages. We show that the Andréka–Németi generalization is the smallest equivalence relation containing the Barrett–Halvorson generalization and it is equivalent to intertranslatability, which is another definition for definitional equivalence, even for non-disjoint languages. Finally, we investigate which definitions for definitional equivalences remain equivalent when we generalize them for theories in non-disjoint languages. (shrink)

Analytische annotatie: Persoonlijk getint filosofisch essay over de vraag waarom de mens de beperkte tijd die hij tot zijn beschikking heeft zo vaak besteedt aan zinloze zaken. De auteur onderzoekt daarbij aan de hand van denkers als De Beauvoir, Kierkegaard en Heidegger of er een andere, intensere omgang mogelijk is met de tijd die ons gegeven is."--Publisher information.

Hematopoiesis unfolds within the bone marrow niche where hematopoietic stem cells (HSCs) play a central role in continually replenishing blood cells. The hypoxic bone marrow environment imparts peculiar metabolic characteristics to hematopoietic processes. Here, we discuss the internal metabolism of HSCs and describe external influences exerted on HSC metabolism by the bone marrow niche environment. Importantly, we suggest that the metabolic environment and metabolic cues are intertwined with HSC cell fate, and are crucial for hematopoietic processes. Metabolic dysregulation within the (...) bone marrow niche during acute stress, inflammation, and chronic inflammatory conditions can lead to reduced HSC vitality. Additionally, we raise questions regarding metabolic stresses imposed on HSCs during implementation of stem cell protocols such as allo‐SCT and gene therapy, and the potential ramifications. Enhancing our comprehension of metabolic influences on HSCs will expand our understanding of pathophysiology in the bone marrow and improve the application of stem cell therapies. (shrink)

The aim of this exploratory cross-sectional study was to examine the associations among relationship status, identity processes, and self-construals among Polish young adults. The theoretical framework of the study consisted of Erikson’s psychosocial theory of human development, the dual-cycle model of identity formation, and the concept of independent and interdependent self-construals. A total of 291 university students aged 20-25 completed the Dimensions of Identity Development Scale and Self-Construal Scale. Results showed that single individuals scored higher on exploration in breadth, exploration (...) in depth, and ruminative exploration, and lower on commitment making and identification with commitment than did partnered individuals. Further, single and partnered individuals did not differ in the area of independent and interdependent self-construals. Discriminant function analysis revealed that especially ruminative exploration and exploration in breadth were important variables for discriminating single from partnered status. (shrink)

How are masculinity and nationalism intertwined? This question has received scant theoretical attention, and existing theories tend to focus on their shared ideals and are embedded in a heteronormative, homophobic, and patriarchal framework. Such views imply a static relationship between the two phenomena and are incompatible with the recent phenomenon of homonationalism and the incorporation of some homosexual bodies within the nation. Addressing this theoretical gap, this article develops a more holistic framework of the relationship between nationalism and masculinity. Drawing (...) on relational sociology, it conceptualises nationalism as competing masculinities. It argues that the link between masculinities and nationalism is not found in their overlapping substantive ideals, but rather that the two phenomena are co-constructed through their overlapping Othering processes. The proposed theoretical framework does not only provide a more dynamic understanding of the link between masculinity and nationalism, but it also helps to overcome the apparent duality between homonationalism and heteronationalism. It is shown that both phenomena are in fact two sides of the same coin, with the main difference between them being the location of homophobia as a technology of Othering within different types of Self/Other relations. Overall, the article provides an analytical tool that allows for the contextualisation and understanding of seemingly contradictory features of nationalism and its relationship to masculinity.

The aim of this paper is to present a new logic-based understanding of the connection between classical kinematics and relativistic kinematics. We show that the axioms of special relativity can be interpreted in the language of classical kinematics. This means that there is a logical translation function from the language of special relativity to the language of classical kinematics which translates the axioms of special relativity into consequences of classical kinematics. We will also show that if we distinguish a class (...) of observers in special relativity and exclude the non-slower-than light observers from classical kinematics by an extra axiom, then the two theories become definitionally equivalent. Furthermore, we show that classical kinematics is definitionally equivalent to classical kinematics with only slower-than-light inertial observers, and hence by transitivity of definitional equivalence that special relativity theory extended with “Ether” is definitionally equivalent to classical kinematics. So within an axiomatic framework of mathematical logic, wee xplicitly show that the transition from classical kinematics to relativistic kinematics is the knowledge acquisition that there is no “Ether”, accompanied by a redefinition of the concepts of time and space.

The discussion about the impact of agricultural biotechnology on Africa is deeply divided and contains widely diverging claims about the impact of biotechnology on African farmers. Building upon literature on the ‘good farmer’ that highlights that farmers identities are an important factor in explaining the success or failure of agricultural change, we argue that the identity of the farmer is an undervalued yet crucial aspect for understanding the debate about the impact of agricultural biotechnology on African farmers. In this article (...) we therefore investigate what farmers’ identities are implicated in the arguments about the impact of biotechnology on African farmers. We aim to identify the main fault lines in different accounts of the African biotechnology farmer by analysing the identities ascribed to them in two prominent cases of controversy: the debates at the 2002 World Summit on Sustainable Development in Johannesburg and the discussion about the impact of biotechnology on smallholder farmers in the Makhathini flats in KwaZulu Natal, South Africa. Our findings demonstrate that arguments about biotechnology are informed by diverging conceptions of who the African farmer is, what is important for the African farmer, and what role the African farmer has in relation to agricultural biotechnology. These findings remain relevant for current discussions on gene editing technologies like CRISPR-Cas. Openly discussing these different views on the identity of smallholder farmers is crucial for moving forward in the biotechnology controversy and can inform future attempts to elicit the farmer’s voice.

Voor de taalgebruiker spreekt taal vanzelf, maar de taalonderzoeker staat voor raadsels. Woordvormen lijken in niets op hun betekenis. En taalconstructies lijken onlogisch in elkaar te zitten. Toch kunnen we in een enkele zin onze bedoelingen tot in de subtielste nuances duidelijk maken. We hebben geen toegang tot het bewustzijn van de Ander maar kunnen desondanks gedachten met elkaar uitwisselen. We kunnen de werkelijkheid met elkaar bespreken en fictieve werelden met elkaar delen alsof ze toch ergens buiten onszelf bestaan. De (...) taalgebruiker heeft er allemaal geen moeite mee. In De magie van taal brengt Net Koene stap voor stap in kaart wat zich in ons hoofd afspeelt wanneer we naar de Ander luisteren. Ze isoleert taalvormen, woorden, constructies, toonhoogte- en ritmekenmerken die we als informatief herkennen in wat de Ander zegt. Ze laat zien hoe al die vormen systematisch hun eigen bijdrage leveren aan onze voorstelling van waar de Ander het over heeft. De auteur toont deze processen vanuit een denkbeeldig alwetend perspectief, in dit boek Omega genoemd. Binnen dit theoretische kader legt ze per hypothese verband tussen wat in het bewustzijn opkomt en de machinerie van het brein: hoe vormt de wereld van onze zintuigen zich, hoe komt ons voorstellingsvermogen tot stand, hoe transformeert de zintuiglijke wereld in een bespreekbare wereld? En vooral: hoe werkt het dat we de inhoud van ons bewustzijn op dat van de Ander kunnen afstemmen? (shrink)

Welch :263–279, 2017) has recently proposed two possible explanations for why the field of evolutionary biology is plagued by a steady stream of claims that it needs urgent reform. It is either seriously deficient and incapable of incorporating ideas that are new, relevant and plausible or it is not seriously deficient at all but is prone to attracting discontent and to the championing of ideas that are not very relevant, plausible and/or not really new. He argues for the second explanation. (...) This paper presents a twofold critique of his analysis: firstly, the main calls for reform do not concern the field of evolutionary biology in general but rather, or more specifically, the modern evolutionary synthesis. Secondly, and most importantly, these calls are not only inspired by the factors, enumerated by Welch, but are also, and even primarily, motivated by four problematic characteristics of the modern synthesis. This point is illustrated through a short analysis of the latest reform challenge to the modern synthesis, the so-called extended evolutionary synthesis. We conclude with the suggestion that the modern synthesis should be amended, rather than replaced. (shrink)

Social workers must often decide about priority at a case level, in a context of scarce resources. These decisions are disputable and controversial, which raises the question on what grounds are they made in practice. This article addresses that question through an empirical study of real-life case discussions in youth care in Flanders, the Dutch-speaking part of Belgium. Toulmin’s argumentation model is used to analyse the data. The study finds that most case discussions are processed in a rather technical manner. (...) But where there is active deliberation, key incidents show that the decision-makers undertake active and personal interpretation of the situation at hand, and that they also take a personal stance on the criteria for assigning priority. In other words, their practice can be understood as a hermeneutical activity. The article’s main conclusion is that the prioritisation process illustrates the moral-political core that is present in any social work decision-making practice. As this moral-political core seems to be hidden most of the time behind a technical-rational approach, questions remain whether the professionals involved are aware that it characterises their own judgements and whether insights into its nature are stimulated.

We investigate empirically whether framing in general, and the use of Simplifying Models as a framing tool in particular, has an effect on the way topics are cognitively construed. Existing studies on framing in linguistics have either been theoretical or descriptive. Going beyond such methodologically simple approaches, we use a more rigid test design involving the use of a control group, the construction of test conditions in which different Simplifying Models constitute the major source of variation, the inclusion of independent (...) variables like age and prior knowledge of the subjects, and the use of linear and logistic regression analysis. Our results show that our more rigid methodological approach yields a more reliable image of the effect of Simplifying Models on the way in which people deal with information on a complex topic like sustainable food production. Fleshing out these effects further may in time lead to a better informed construction of communication on complex social topics. (shrink)

It is argued that feature creation may not only depend on categorical distinctions that are made during category learning, but also on the choice set during subsequent categorization.

The purpose of the present contribution is to explore how the ECJ seeks to respect the principles underpinning national welfare systems, notably social solidarity, whilst ensuring that Member States comply with the substantive law of the European Union, in particular with the Treaty provisions on the fundamental freedoms and EU citizenship. It is submitted that in order to reconcile those two interests the ECJ has taken the view that nationals of the host Member State must show a certain degree of (...) financial solidarity with the nationals of other Member States who have established a ‘genuine or real link’ with the society of that State. With a view to establishing the existence of such a link, national authorities of the host Member State must engage in a case-by-case assessment of the personal circumstances of the EU citizen claiming social benefits. However, Förster is an important exception to the individual application of the ‘genuine or real link’ test. Although Förster does not overrule Bidar as a matter of principle, it exempts the host Member State from examining the personal situation of economically inactive students who apply for maintenance grants or student loans but have not yet completed a five-year period of residence.

It is well known that the commercial and political decline of the United Provinces in the eighteenth century was discussed throughout Europe. The aim of this introductory article and this special issue on ‘Dutch Decline in Eighteenth-Century Europe’ at large is to take a first few steps towards developing a new understanding of these discussions. Rather than to attempt to provide an inventory of which foreign writers reflected on the Dutch case and analyse their judgements, the purpose of this introduction (...) is to establish the nature of this interest in the light of the changing dynamics of interstate political and trade relations. Consisting of two parts (each divided in two sections), this introductory article is an attempt to bring together into the same frame, one, the concerns that moved major and lesser figures to discuss the Dutch case and, two, the wealth of economic history studies that have addressed the notion of Dutch decline. In order to eventually make these historiographies mutually productive, it is argued that the idea of ‘intrinsic power’ needs to be recognised not primarily as related to an idea of ‘relative’ (as opposed to ‘absolute’) decline, but in a slightly different fashion. The way in which Dutch political writers increasingly came to understand the predicament of their state and ultimately aligned themselves with their European counterparts was precisely through the concept of ‘intrinsic power’, understood as a comparative notion that referred to the ramifications of political shifts for the capacity of the Dutch Republic to maintain itself on the international scene.

Attracting philosophers, politicians, artists as well as the educated reader, Edmund Burke’s Philosophical Enquiry, first published in 1757, was a milestone in western thinking. This edited volume will take the 250th anniversary of the Philosophical Enquiry as an occasion to reassess Burke’s prominence in the history of ideas. Situated on the threshold between early modern philosophy and the Enlightenment, Burke’s oeuvre combines reflections on aesthetics, politics and the sciences. This collection is the first book length work devoted primarily to Burke’s (...) Philosophical Enquiry in both its historical context and for its contemporary relevance. It will establish the fact that the Enquiry is an important philosophical and literary work in its own right. (shrink)

Neither can we... improve a science, without improving the language or nomenclature which belongs to it.Ludwig Wittgenstein famously claimed that it was the task of scientists to investigate matters of fact, whereas philosophers merely had to clarify the meaning of terms. One could also—or more precisely—argue that philosophers should identify and remedy five kinds of possible dysfunctions in the relationship between epistemic terms and their referent: they can be meaningless, imprecise, indiscriminate, ambiguous, or inapt. One of the main reasons why (...) “Darwinism” is an inapt term is that it has ideological connotations, like Marxism and similar “ism” words (Greene 1986; Roger... (shrink)

I argue that the imagination was a crucial concept for the understanding of marvellous phenomena, divination and magic in general. Exploring a debate on prophecy at the turn of the seventeenth century, I show that four explanatory categories were consistently evoked and I elucidate the role of the imagination in each of them. I introduce the term ‘floating concept’ to conceptualise the different ways in which the imagination and the related ‘animal spirits’ were understood in diverse discourses. My argument is (...) underpinned with a general discussion of the imagination, after which I focus on a unorthodox tradition which attributed special powers to this internal faculty. Many physicians had explained psychosomatic phenomena by referring to the influence of the imagination on the human body; but some philosophers held that the imagination could also exert power over external objects. During the renaissance these theories acquired negative associations and became linked with illicit magic. Furthermore, I show that the relation between both animal spirits and imagination, and the power of the latter over external bodies, points to the importance of a ‘history of vapours’; and this suggests an adjustment to Keith Hutchison’s argument on occult qualities in mechanical philosophy. The accompanying paper gives more evidence of these claims and elaborates on the relation between the natural and the moral. (shrink)

What could a social-justice oriented, feminist data studies look like? The current datalogical turn foregrounds the digital datafication of everyday life, increasing algorithmic processing and data as an emergent regime of power/knowledge. Scholars celebrate the politics of big data knowledge production for its omnipotent objectivity or dismiss it outright as data fundamentalism that may lead to methodological genocide. In this feminist and postcolonial intervention into gender-, race- and geography-blind ‘big data’ ideologies, I call for ethical, anti-oppressive digital data-driven research in (...) the social sciences and humanities. I argue that a reflexive data scholarship can emerge from the reintegration of feminist and postcolonial science studies and ethics of care ideals. Although it is not a panacea for all ails of data mining, I offer a road map for an alternative data-analysis practice that is more power-sensitive and accountable. By incorporating a people-centric and context-aware perspective that acknowledges relationships of dependency, reflects on temptations, and scrutinises benefits and harm, an ‘asymmetrically reciprocal’ (Young, 1997) research encounter may be achieved. I bring this perspective to bear on experiences of a two-year research project with eighty-four young Londoners on digital identities and living in a highly diverse city. I align awareness of uneven relations of power and knowledge with the messy relation of dependency between human and non-human actors in data analysis. This framework productively recognises that digital data cannot be expected to speak for itself, that data do not emerge from a vacuum, and that isolated data patterns cannot be the end-goal of a situated and reflexive research endeavor. Data-driven research, in turn, shows the urgency for renewed feminist ethical reflection on how digital mediation impacts upon responsibility, intersectional power relations, human subjectivity and the autonomy of research participants over their own data.

This article contributes to the debate about how regulatory science for agricultural technologies can be ‘opened up’ for a more diverse set of concerns and knowledges. The article focuses on the regulation of ‘socio-economic considerations’ for genetically modified organisms. While numerous countries have declared their intent to include these considerations in biotechnology decision-making, it is currently unclear both what counts as a socio-economic consideration and how such considerations should be assessed. This article provides greater clarity about how socio-economic considerations can (...) be included in regulations by drawing upon the experience of two countries whose efforts in this field are particularly advanced: Kenya and South Africa. Based on extensive fieldwork, this article identifies the contours of an emerging regulatory regime by presenting two practice-based models for including socio-economic considerations in biotechnology decision-making. Whereas Kenya has taken a bottom-up process prior to assessing the first technologies and strongly emphasises scientific expertise, South Africa has instead established regulatory standards in an ad hoc fashion on a case-to-case basis, with a less prominent role for scientific evidence. The discussion of the distinct characteristics and tensions of both models provides insight into two potential pathways for including socio-economic considerations in the regulation of agricultural technologies.

This book presents a thorough and critical evaluation of the monetary and financial system prevalent in Western economies. Further, it seeks to explain why this system so often leads to financial crises and why they have been dealt with unsatisfactorily in the past. In order to provide answers to these questions, the book investigates the monetary and financial system from a multidisciplinary perspective, with a strong focus on the ethical value choices which throughout history have shaped the monetary and financial (...) legal system. In the closing chapters, the book also advances a detailed proposal for a New Global Monetary Order, one based on altruism, as an alternative to the neoliberal values dominant today. (shrink)
