This essay pushes the history of a scientific discipline, morphology, toward a broader philosophically informed and cross-disciplinarily engaged history of knowledge. It shows that by looking at how knowledge and practices circulated between scientific disciplines (such as biology) and technoscientific ones (like architecture and design) we can better understand how (morphological) knowledge was produced. By doing so, the analysis contributes to the study of the mechanisms of knowledge exchange between the organic and the technical worlds and, more broadly, to the (...) study of the dynamics of knowledge circulation. First, the essay analyzes the engineering studies of organic form conducted by the Austro-Hungarian botanist Raoul Heinrich Francé (1874–1943) and the Scottish polymath D’Arcy Wentworth Thompson (1860–1948). Subsequently, the essay moves to twenty-first-century morphogenesis. It examines the transfer of the notion of morphospace, a paleontological practice of data visualization, into biology-inspired architectural design. The conclusion deals with the broader features of knowledge transfer and circulation. Twentieth- and twenty-first-century morphologists successfully translate and transfer morphogenetic processes from nature into technical artifacts to achieve technical solutions to given problems. In the translation of organic morphogenesis into a technical process, evolution’s intrinsic historical contingency was deliberately left behind. (shrink)

The following paper aims to explore the plausibility of considering movement and place part of the conventionality of social life and interactions from an ethnomethodological point of view and asks whether there is a conventionality to the very distinction between actions being ‘mobile’ and/or ‘inert’—if we can speak of this as, at least in part, conventional, then we can further ask, whether this conventionality plays a part in the social construction of space and the socio-spatial order more generally. After arriving (...) at this question by looking at Giddens and Garfinkel, the paper differentiates four types of movement: drifting, circling, mobility, and circulating. The latter is then used to show how a key aspect of social order is not simply experience of being ‘enclosed’ by a boundary or division of space, but that instead, most of the time, spatial order is simply taken for granted and movement is experienced and neither ‘here’ nor ‘there’. Circulation, then, helps us to account for our ability to move within a place without necessarily having to leave it. Circulation describes the process of accomplishing the interiority of a place and the paper will claim that this is achieved by glossing over particular borders and boundaries as we traverse space.

A major obstacle to chemistry being a deductive science is that its core concepts very often are defined in a circular manner: it is impossible to explain what an acid is without reference to the complementary concept of a base. There are many such dual pairs among the core concepts of chemistry. Such circulation of concepts, rather than an infirmity chemistry is beset with, is seen as a source of vitality and dynamism.

This essay presents the early days of human cytogenetics, from the late 1950s until the mid 1970s, as a historical series of images. I propose a chronology moving from photographs of bodies to chromosome sets, to be joined by ultrasound images, which provided a return to bodies, by then focused on the unborn. Images carried ontological significance and, as I will argue, are principal characters in the history of human cytogenetics. Inspired by the historiography of heredity and genetics, studies on (...) visual cultures, the conceptualization of circulation, and the sociology of pregnancy, I suggest that cytogenetics, through its focus on pregnancy, pregnant women, and their offspring, found strategic living materials that stabilized human chromosome studies as a biomedical, post-eugenics practice. The historicity of each path displays a wide circulation of objects, tools, and methods that condensed on images that shared in the centuries-old visual expertise that medicine and botany had manufactured.

Circulating the Code: Print Media and Legal Knowledge in Qing China. By Ting Zhang. Seattle: University of Washington Press, 2020. Pp. xi + 252. $95, $30.

This special issue looks at some of the ways that images are adopted, co‐opted, and adapted in the life sciences and beyond. It brings together papers that investigate the role of visualization in scientific knowledge‐production with contributions that focus on the distribution and dissemination of knowledge to a broader audience. A commentary provides a critical perspective. In this editorial we introduce circulation as a practice to better understand scientific images. Along two themes, we highlight connections across the papers. First, (...) the social life of scientific representation follows the contexts, settings, and spaces through which images circulate. Second, authorship, expertise, and trust inform the capacity and the failure of images to circulate. Altogether, this volume raises a set of new questions about circulation as practice in the historiography of images in the life sciences. (shrink)

Existentialism has come to be identified as a critical, reactionary way of thinking, celebrating the individual, freedom, embodiment, and the limits of rationality and systematic theorizing. For the most part this assessment is true of the early and, by now, “classical” works of existentialism, those that first burst upon the philosophical and cultural scene. Circulating Being centers on the later works of several well-known French existentialists (Camus, Marcel, Sartre, Merleau-Ponty) to trace out the development of their existential thinking about language, (...) communicative life, ethics, and politics. This development “from embodiment to incorporation” carries existentialism beyond identification with the mere reactionary and reveals how, while prefiguring postmodernism in important ways, the existential thinkers dealt with here reveal themselves to be reconstructive of the Western tradition. This is apparent in the growing appreciation of difference in their late works along with a reluctance to surrender the ideal of unity, and in their reappropriation of truth and justice while repudiating a totalizing metaphysics.

The articles by Bernat, Busch, Dudzinski et al., and Derse illustrate the difficulties with reconciling normothermic regional perfusion (NRP) with the dead donor rule (DDR) (Bernat forthcoming; Busch forthcoming; Dudzinski et al. forthcoming; Derse forthcoming). I appreciate their arguments because they help illuminate the issues that generate a dilemma: either reject NRP or the DDR. I am convinced that the dilemma is unavoidable because the procurement team is involved with determining and securing the death of the donor when circulation (...) restarts. Evidence for this is found in the reasons and recommendations given for blocking blood flow to the brain, both of which betray a lack of certainty over the donor’s vital status. The surgical activity in NRP therefore conflicts with the values the DDR protects: respect for the donor’s life and avoidance of conflict of interest. (shrink)

This article examines the phenomenon of the “global circulation of low-end expertise” through an exploration of the social dynamics surrounding American oil drillers who migrated from the Pennsylvania oil region to British colonial Burma during the early 1900s to the mid-1930s. These working-class drillers, with practical knowledge in oil drilling acquired through familial and community networks, played a crucial role in operating mechanized oil wells and providing geological expertise in colonial Burma. Positioned between labor-intensive agricultural economies in colonial Asia (...) and the higher echelons of British colonial society, these drillers occupied an intermediate social location. Despite their indispensable expertise, they were marginalized due to their lower social standing, leading to their expertise being disregarded by their superiors and forgotten over time. By understanding the complexities of the “global circulation of low-end expertise,” this study sheds light on the social construction and erasure of the expertise held by these working-class drillers, revealing overlooked aspects of global histories of science and labor and highlighting the need to reassess dominant historical narratives on knowledge-labor.

The Song Empire (960–1279 CE) had a larger population, a higher agricultural output, a more efficient infrastructure, and a more extensive monetary system than any previous empire in Chinese history. As local jurisdictions during the eleventh century became entangled in empire-wide economic relations and trans-regional commercial litigation, imperial officials sought to reduce the bewildering movement of people, goods, and money to an immanent cosmic pattern. They reasoned that because money and commerce brought to imperial subjects the goods they required to (...) survive, money and commerce must be beneficent, and because they were beneficent, they must conform to the immanent pattern of the moral cosmos, as did everything else that was enduringly sustaining of life and wellbeing. And because money and commerce conformed to the moral cosmos, officials attempted to understand their workings by analogy with other phenomena that sustained human life, such as the flow of water and the circulation of vital essences through the human body. During the 1030s and 1040s, officials and scholars believed that knowledge of the cosmic pattern lay within their grasp, and that this knowledge would allow them to align culture with nature, and the present with hallowed antiquity. By the 1080s, however, this intellectual optimism had been defeated by irreconcilable disagreements about financial and economic policy. The failure of the attempt to understand finance by natural analogy draws attention to the underlying ideological insistence on moral learning as the basis for political power, and to the very limited range of economic discourse that has been preserved in eleventh-century texts.

In 1628, Harvey published his blood circulation theory, which triggered questionings by Riolan and Descartes at several levels: metaphysical, physiological, anatomical, institutional. The blood controversy tackles various conceptions of life that refer to various metaphysical backgrounds (Aristotelician, Cartesian or Neoplatonic), several kinds of relationships between natural philosophy and theology (compatibility, strict distinction, a balance between the two), distinct representations of the human body (dynamic, mechanic, aesthetic). It illustrates a point in time when medicine reforms and reorganizes its epistemic style (...) and its rationality in order to explain the complexity of the body’s fabric. (shrink)

Bruno Latour claims to have shown that a Kantian model of knowledge, which he describes as seeking to unite a disembodied transcendental subject with an inaccessible thing-in-itself, is dramatically falsified by empirical studies of science in action. Instead, Latour puts central emphasis on scientific practice, and replaces this Kantian model with a model of “circulating reference.” Unfortunately, Latour's alternative schematic leaves out the scientific subject. I repair this oversight through a simple mechanical procedure. By putting a slight spin on Latour's (...) diagrammatic representation of his theory, I discover a new space for a post-Kantian scientific subject, a subject brilliantly described by Ludwik Fleck. The neglected subjectivities and ceaseless practices of science are thus re-united. (shrink)

We study a class of two-player normal-form games with cyclical payoff structures. A game is called circulant if both players’ payoff matrices fulfill a rotational symmetry condition. The class of circulant games contains well-known examples such as Matching Pennies, Rock-Paper-Scissors, as well as subclasses of coordination and common interest games. The best response correspondences in circulant games induce a partition on each player’s set of pure strategies into equivalence classes. In any Nash Equilibrium, all strategies within one class are either (...) played with strictly positive or with zero probability. We further show that, strikingly, a single parameter fully determines the exact number and the structure of all Nash equilibria in these games. The parameter itself only depends on the position of the largest payoff in the first row of one of the player’s payoff matrix. (shrink)

Avec l'essor des journaux spécialisés, le paysage éditorial mathématique évolue considérablement pendant la première moitié du xixe siècle. Parallèlement, la publication des Disquisitiones arithmeticae de Gauss en 1801, avec son introduction de la notion de congruence, marque l'histoire de la théorie des nombres. Cet article propose une analyse de la double évolution du paysage éditorial et des congruences dans la première moitié du xixe siècle, en se concentrant sur les circulations mathématiques. Après avoir identifié le corpus des textes par lesquels (...) la notion de congruence circule, nous en dressons un portrait général avant de nous focaliser sur des cas d'étude particulièrement significatifs. Congruences et périodiques sont ainsi envisagés, tour à tour, comme des objets et des moyens d'étude. (shrink)

In this contribution, we analyse the treatment of professional practice in two training sequences dedicated to the teaching of written French. Firstly, we examine the characteristics of the training devices organised with a combination of school field and training institution scheme. We then focus on interactions between trainer and trainees within two training activities aimed at sharing and reflecting on practicum. The interest of this double perspective lies in the understanding of knowledge circulation between school field and training institution (...) and how this circulation serves the development of teachers’ action.

We invite systematic consideration of the metaphors of cycles and circulation as a long-term theme in the history of the life and environmental sciences and medicine. Ubiquitous in ancient religious and philosophical traditions, especially in representing the seasons and the motions of celestial bodies, circles once symbolized perfection. Over the centuries cyclic images in western medicine, natural philosophy, natural history and eventually biology gained independence from cosmology and theology and came to depend less on strictly circular forms. As potent (...) ‘canonical icons’, cycles also interacted with representations of linear and irreversible change, including arrows, arcs, scales, series and trees, as in theories of the Earth and of evolution. In modern times life cycles and reproductive cycles have often been held to characterize life, in some cases especially female life, while human efforts selectively to foster and disrupt these cycles have harnessed their productivity in medicine and agriculture. But strong cyclic metaphors have continued to link physiology and climatology, medicine and economics, and biology and manufacturing, notably through the relations between land, food and population. From the grand nineteenth-century transformations of matter to systems ecology, the circulation of molecules through organic and inorganic compartments has posed the problem of maintaining identity in the face of flux and highlights the seductive ability of cyclic schemes to imply closure where no original state was in fact restored. More concerted attention to cycles and circulation will enrich analyses of the power of metaphors to naturalize understandings of life and their shaping by practical interests and political imaginations.

This essay argues that trans philosophy - and perhaps philosophy more broadly - should be understood according to the interplay of social, material, and emotional circulations. It opens by bridging insights from underemployed library work during the COVID-19 pandemic with Sara Ahmed’s analysis of the circulation of emotions in relation to texts and archives. The first major section diagnoses Martha Nussbaum’s confusing analysis of “the new trans scholarship” to establish that trans philosophy is differentially circulated across the discipline of (...) philosophy. The second major section argues that trans philosophy can be understood through the interplay of four different circulations: (1) trans philosophy as creating a space; (2) trans philosophy as the trans question; (3) trans philosophy as the gender wars; and (4) trans philosophy as the trans cult. I conclude that trans philosophy is a field that has yet to clearly form as it continues to twist and multiply according to affect, professional dynamics, political intrigue, who gets thrown away, and who is granted the space, time, energy, and money to write and publish.

In lieu of an abstract, here is a brief excerpt of the content:Rhetorical Circulation in Late CapitalismNeoliberalism and the Overdetermination of Affective EnergyCatherine ChaputIn the world we have known since the nineteenth century, a series of governmental rationalities overlap, lean on each other, challenge each other, and struggle with each other: art of government according to truth, art of government according to the rationality of the sovereign state, and art of government according to the rationality of economic agents, and (...) more generally, according to the rationality of the governed themselves. And it is all these different arts of government, all these different types of ways of calculating, rationalizing, and regulating the art of government which, overlapping with each other, broadly speaking constitute the object of political debate.Michel Foucault, The Birth of BiopoliticsCritical rhetoricians interested in the power dynamics between rhetoric and capitalism have established for themselves the ambitious task of explaining how multiple, intertwined rationalities govern individual and collective [End Page 1] behavior in relationship to the ever-shifting logics of capitalism. Approaches to this complicated directive frequently envision rhetoric as a mediating force among agentive subjects who act within well-defined political economic landscapes. Wedded to a political-communicative model wherein appropriate rhetorical choices persuade those with authority to distribute disputed political and economic rights, rhetorical theory becomes a sophisticated handbook for discovering topoi and executing decorous statements. This focus, according to Ronald Walter Greene, results in a "permanent anxiety over the meaning and potential of rhetorical agency" that positions rhetoricians as "moral entrepreneurs scolding, correcting, and encouraging the body politic" (2004, 188, 189). Committing themselves to endless debates about correct responses in situated spaces, rhetorical theories that underscore agency lose site of the world in flux and of our participation in that world's unpredictable unfoldings. Alternatively, Greene suggests rethinking rhetorical theory through a materialist-communicative model wherein the immaterial labor of communication produces value. Conceptualizing discursive practices as a form of labor rather than a form of political signification sidesteps anxiety about well-chosen language and emphasizes the life-affirming activity involved in deciphering issues, inventing paths through those issues, and communicating new ideas to others. In short, Greene's materialist model challenges critical rhetoricians to end their perennial search for a discursive key to the storehouse of political economic goods (a practice propelled by liberal democratic hopes) so that they can begin to invent analyses and modes of production better suited to the contours of contemporary neoliberalism.Unlike liberalism's clearly assigned spaces for public life and private life or work time and leisure time, neoliberal spaces bear few obvious markers. The neoliberal landscape consists of blurred boundaries that fold into one another: information flows almost instantaneously, commodities and people transgress national boundaries, time accelerates, space collapses, and distinctions between such classic demarcations as agent and subject or politics and economics erode. Facilitated by dramatic changes in our sociopolitical boundaries, economic neoliberalism, what James Arnt Aune calls "economic correctness" (2001), reigns throughout vast uneven terrains opened up from the imploded borders of our liberal world. While economics does indeed rule the neoliberal landscape, it does not do so according to uncompromising rationalism. Political and cultural practices flowing into the previously segregated spaces of economics enable market rule through logics that operate entirely outside the rational-irrational divide. Economic neoliberalism moves from situation to situation, disregarding spatial boundaries between the political, economic, [End Page 2] and cultural realms as well as their attendant modes of persuasion, wearing away at the rhetorical linkages between appropriate discursive choices and agentive power.Regardless of the particularities of neoliberalism's spaces, structures, and governing practices, many rhetoricians continue to mediate among different worldviews based on outmoded liberal gauges. Some rhetorical theorists, for instance, maintain that the problematics of neoliberalism result from an imbalance between reason and passion. Even though the most ardent supporters of neoliberal practices hold firmly to a belief in its scientific rationality, rhetorical theorists often argue that passion overpowers reason in neoliberal discourse. The rhetorical form that sustains this disequilibrium is, according to Bradford Vivian, neoliberal epideictic. Based on an impassioned identification, epideictic texts "unite an otherwise fractured citizenry in a dynamic affective experience" (Vivian 2006, 15). Epideictic rhetoric functions didactically to unite the public... (shrink)

The purpose of this study is to conceptualize and theorize the circulation-chain model as an education policy implementation framework systematically. The circular-chain education policy implementation process and effect evaluation analysis model are a theoretical innovation model and practical exploration path to explore the implementation and effect evaluation of education policies according to the new problems and trends in the implementation of education policies. In particular, the connotation, the theoretical basis, the elements, the value, and the objective and significance of (...) the circulation-chain education policy implementation model have been explored and analyzed in this study.

Most conceptual models of the organization of the cardiovascular system begin with the premise that the nervous system regulates the metabolic and nonmetabolic reflex adjustments of the circulation. These models assume that all the neurally mediated responses of the circulation are reactive, i.e., reflexes elicited by adequate stimuli. This target article suggests that the responses of the circulation are conditional in three senses. First, as Sherrington argued, reflexes are conditional in that they never operate in a vacuum (...) but in a context together with other reflexes. Guided by functional utility, they interact rather than add. Second, as Pavlov argued, stimuli acquire meanings as a result of experience. This notion of stimulus effect plus the Sherringtonian notion of conditionality suggest that association is one of the ways stimuli eliciting cardiovascular reflexes acquire their meanings and thus their relative strengths. Finally, as Skinner and others have argued, operants are responses that act upon the environment to obtain consequences – that is, stimuli. As operants, cardiovascular responses fulfill a major biological need, functioning proactively. The cardiovascular response is an integral component of the animal's behavior regardless of whether it is an elicited reflex or the eliciting stimulus acquired its properties as a result of the genetic inheritance of the animal or through experience, or the cardiovascular response is emitted in anticipation of an environmental consequence. The main theses of this essay are: (1) behavior is an integrated set of responses and the circulation is one of the response systems comprising behavior; (2) behavior is, in part, determined by its functional significance within a context; (3) the contextual factors operative at the time of the behavior have a major role in determining which of the set of possible responses will determine the final act, that is, which behavior will be the effective response and which other behaviors will be concomitants.

This paper investigates interdiscursivity in talk about gender norms in the Lesbian, Gay, Bisexual, Trans, Queer community. Drawing from field work conducted among gay and lesbian parents, transgender people, and the Drag King community, I show how accounts like les hommes sont comme ça or les femmes sont comme ça emerging in discourse about pregnancy reveal gender-based norms and their relationship to social conditions. Adopting a linguistic anthropology perspective, while paying particular attention to agency, categorization, circulation, and recontextualization processes, (...) I show how gender norms are constructed and deconstructed through interactional, semantic, and morphosyntactic patterns found in a variety of multisemiotic mediums and in a diversity of contexts. In addition to its contribution to the study of gender and language, this article takes new steps in the ongoing development of membership categorization analysis and queer linguistics. (shrink)

The protests at the Universiteit van Amsterdam (UvA) that began in November 2014 as a reaction to severe cuts in the department of humanities have sparked a broad debate nationally and even internationally about the future of the university and the values and ideals that should define it. It turned out that dissatisfaction was much more widespread in different parts of the university than some had previously thought, and many turned out to share the concerns first put forward in the (...) humanities department, to extend beyond the borders of the university and the country. Increasing focus on getting as many students as possible to graduate promptly has shifted the attention ever more towards quantitative indicators for the evaluation of education rather than qualitative ones, leading to raising the question of whether the quality of education has suffered from these priorities. How did this come about and what could be done to improve this quality? In this essay we briefly consider the history of the university as an institute that aims to combine research and education, subsequently mentioning some more recent challenges for the university, finishing it with a brief description of a ‘circulation model of education’ that we consider to be a fruitful source for answering some of the challenges we identified from the current discussions. In this model circulation rather than unidirectional traffic occurs between different elements: circulation between research and education, between insights of teachers and of students, between disciplines, between general and contextualized knowledge, between disciplinary and experi- ential knowledge, between doing research and (meta-)reflection upon research, and so on.

En portant l’attention sur la ville de Troyes, petite cité manufacturière et commerçante du département de l’Aube, entre 1820 et 1850, cet article examine l’offre publique d’enseignement mathématique à l’échelle de la ville afin de mettre en lumière d’éventuelles circulations mathématiques entre les divers types d’institutions post-élémentaires – primaire, secondaire, technique – qui la composent.

Avec les individus, ce sont aussi des savoirs, des pratiques, des habitudes de travail qui franchissent les frontières institutionnelles et se confrontent éventuellement à d’autres systèmes de normes.

There are many case studies showing the benefits of the conceptual framework of Actor– Network Theory. It is enough to mention the classic texts by Bruno Latour on the Amazon forest and Michel Callon on scallop fishing. However, there are not many case studies discussing the circulation of knowledge in the humanities with the use of vocabulary taken from ANT. This text tries to partially fill the gap, analyzing a case encompassing the areas of both literary studies and philosophy. (...) The main topic of the paper is the circulation of Jacques Derrida’s views – or the views attributed to Derrida – as exemplified by one of his theses. The purpose of the text is not to reflect on the value of Derrida’s reflections, but only to show how the knowledge of his thought spread from France, through the USA, to Poland, from the 1960s to the beginning of the 21st century. Besides proving that the ANT vocabulary is suitable for studying the phenomenon of the circulation of knowledge in the humanities, the case study also shows that this vocabulary should be enriched. The author of the text proposes the concept of symbolization to better understand how Derrida and the ideas attributed to him have been perceived in various texts. (shrink)

This paper presents and discusses the website. Under the title “The Virtual Laboratory: Essays and Resources on the Experimentalization of Life” it gives access to a massive collection of texts and images concerning the experimental life sciences of the 19th and early 20th century. The main focus is on physiology and psychology. Plant breeding is an additional theme. As of now, the Virtual Laboratory gives access to some 12,000 digital items, i.e. historical text books, journal articles, manuscripts, trade catalogs, photos, (...) films, audio files, etc. At the same time, the Virtual Laboratory is a platform for historians of science to publish and discuss their research on the experimentalization of life. Topics range from the history of precision time measurements in the physiological lab to the historical epistemology of hearing and the role of the Axolotl as an experimental animal in zoology. By way of a guided tour through the Virtual Laboratory, the paper describes the kind of epistemic space that was created. It argues that open access to historical sources as well as tight connections between historical research papers and their raw data, e.g. manuscript sources, profoundly change what used to be called the Archive. Today’s historians of science have started to work within a space that is widely distributed and extremely flexible with respect to its internal connections. It is a space that turns the Archive into an authentic laboratory for the science historian. (shrink)

As soon as the SARS‐Cov2 disease was recognized by experts to potentially cause a serious pandemic, a three dimensional diagrammatic image of the virus, colored in strong red, conquered public media globally.This study confronts this iconic virus image with a historic image analysis of 33,000 biomedical articles on coronaviruses published between 1968–2020 and interviews with some of their authors.Only a small fraction of scientific virus publications entail images of the complete virus. Red as an alarm color is not used at (...) all by scientists who don't aim for a non‐scientific public.Circulation in this case concerns the movement of iconic images from a scientific context into a general public. On the basis of hps‐studies on scientific diagrams and especially on color use in scientific diagrams to convey specific messages in public, the paper discusses the role of the claim of public corona‐virus diagram as “scientific.”It points at relevant differences between most frequent scientific corona‐virus images and the diagrammatic image used in public. Both author‐ and readerships (in science and public) follow contrasting aims and values. Thus, the images meet non‐expert readers for whom the images entail very different – and potentially unintended – meanings then to virus experts. (shrink)

Before the popularization of the printing press, the circula­tion of commentarial texts across regional borders, especially of Islamic texts outside of the Middle East, remains largely unexplored. This article focuses on the movement of Islamic manuscripts in the Indian Ocean world, from South and East Africa to South and East Asia. Together with merchants, sail­ors, travelers, and commodities, the books also traveled long distances, replete with ideas, stories, dreams, myths, norms, manners, and emotions. What was the role of manuscripts in (...) the expansion of Islam into the premodern oceanic world and in religio-cultural exchanges between central Islamic lands and the larger world? What sorts of books did people access, read, and use, and what did the circulation of these texts imply? I address these questions with a broad focus on the oceanic littoral and Islamic manuscripts and a specific focus on one of the ports and a legal commentary. Based on this analytical exercise of zooming-out and zooming-in between macro- and micro-maritime textual histories anchored in the sixteenth century, I argue that the citations of specific manuscripts reveal the prominence of a transregional circula­tion of certain texts, along with their contextual cultures of reading, writing, producing, and circulating commentaries.

Because it is provocative and is based on the denigration of absent third parties, shock jock discourse stimulates reactions that go well beyond the initial circle of listeners. Trash radio supporters and detractors alike take up the hosts’ deprecating remarks, reinterpret them and put them back into circulation. As the repetitions multiply, interweaving private speech and public speech, a complex web of circulation forms, attesting to the contagiousness of the discourse and the influence of the radio hosts. In (...) order to capture and explain this mechanism of propagation, we propose a model of analysis that combines elements of linguistic, discursive and pragmatic description. The model is illustrated by a case study. We are led to observe that the extent and rate of propagation of deprecating remarks inevitably affect the image of the person targeted and, more fundamentally, tend to make an aggressive mode of expression part of the natural speechscape.

This article explores the influence of textual structures on the acquisition of knowledge in popularization discourses related to biopesticides. Following a terminological insight into the linguistic and cognitive complexities of the notion, we proceed to a semantic analysis of press articles in major Anglo-Saxon newspapers, focusing on the explanation strategies used by the media to simplify their presentation. We show that in the mediation process, biopesticides are systematically described as being environmentally friendly, and opposed to chemical pesticides, consistently shown to (...) be detrimental to the environment. We hypothesize that this simplistic binary framing is exploited by journalists as it is easy to understand in a context of agroecological transition and commonly shared distrust for chemical pesticides. In that respect, it proves to be adequate for purposes of explanation and simplification. However, by outlining this discursive process based on duality, we aim to draw attention to the potential misconceptions of plant protection issues in general, and biopesticides in particular. We ultimately demonstrate that when adopting other perspectives, this dual framing proves to be inadequate for the construction of knowledge by any non-expert press reader. (shrink)

For nearly two centuries, developmental biologists have known that body organs are derived from distinct germ layers. They have argued that adult stem cells formed in one of these, mesoderm for example, cannot give rise to cells that originate in another. We disagree. An exception to this “rule” has been described in crayfish recently. In this species, hemocytes appear to replenish neurogenic cells. This may happen in humans as well. In women who were given male bone marrow‐derived cells, Y chromosome (...) positive cheek cells and brain neurons were detected. While repopulation of these tissues by bone marrow derived cells may not occur normally, and while it does not appear to be terribly efficient, the phenomenon should be studied in more detail. Perhaps cells in the marrow could be used to regenerate tissues elsewhere. (shrink)

The fundamental determinant of death in donation after circulatory determination of death is the cessation of brain circulation and function. We therefore propose the term donation after brain circulation determination of death [DBCDD]. In DBCDD, death is determined when the cessation of circulatory function is permanent but before it is irreversible, consistent with medical standards of death determination outside the context of organ donation. Safeguards to prevent error include that: 1] the possibility of auto-resuscitation has elapsed; 2] no (...) brain circulation may resume after the determination of death; 3] complete circulatory cessation is verified; and 4] the cessation of brain function is permanent and complete. Death should be determined by the confirmation of the cessation of systemic circulation; the use of brain death tests is invalid and unnecessary. Because this concept differs from current standards, consensus should be sought among stakeholders. The patient or surrogate should provide informed consent for organ donation by understanding the basis of the declaration of death. In cases of circulatory cessation, such as occurs in DBCDD, death can be defined as the permanent cessation of brain functions, determined by the permanent cessation of brain circulation. (shrink)

Roman pottery from Thasos. New evidence on the economy. This study deals with a significant assemblage of pottery dating from the 1st century BC to the end of the 3rd century AD from the excavations of the French School of Archaeology at Thasos. Their quantitative and qualitative analysis, as well as their chronological and geographical context, has allowed the author to develop a new methodological approach to their study, and shed more light on the trade and exchange networks of Thasos. (...) The types of amphorae from this period are not well documented on Thasos. Following the current study, however, we are now able to draw a number of significant conclusions about the material, but more work needs to be done in order to further elaborate on the typology of locally-produced pottery in the Imperial Period. Furthermore, the study of the fine ware pottery has established a broad quantitative data set, and will enable us to assess the nature and extent of imports. (shrink)

Does normothermic regional perfusion (NRP) resurrect the dead? That was the question I asked in one of the target articles published in the special issue of The American Journal of Bioethics (AJOB)...
