This paper considers a key text in the field of Cultural Studies for its relevance to questions about the identity of knowledge in education. The concept of ‘aura’ arises as being of special significance in ‘The Work of Art in the Age of Mechanical Reproduction’ as a way of understanding the change that occurs to art when mass reproduction becomes both technologically possible and industrially realised. Aura seems to signify something of the symbolic halo generated by objects (...) of special significance that is both powerful and indefinite. This paper argues that aura is in fact the necessary property of symbolic representation—and that it attaches as much to the figure of Walter Benjamin as it does to any canonical work of art. But the paper also claims that Benjamin’s argument about the significance of popular forms of art—particularly photography and film—can be updated and applied to critical questions about the established order of knowledge in education. This is particularly relevant to those curriculum domains where specific objects—texts, for example—are invested with powerful auras. It may also be applicable to all forms of established knowledge and curricula. (shrink)

Ron Harris captured the popular imagination in October 1999 with a website where he auctioned off the ova of fashion models to the highest bidder. This article treats the controversy surrounding Harris’ site within a dual frame of critical theory’s approach to reproduction and a folkloristic approach to discourse. The website fuses traditional narrative motifs and structures with the logic of advertising, seventies television, family-values rhetoric, and the fertility industry. I argue that the great attraction of ronsangels.com is that (...) it put into relief the intervention of mechanical reproduction in human fertility together with the state of genetics at the turn of the 21st century. The result is not only a disconcerting aestheticization and commodification of biological reproduction, but also the biological reproduction of a particular aesthetic and moral code—a generation of reality by model.

The methods of intellectual history have not yet been applied to studying the invention of technology for printing texts and images ca. 1375–ca. 1450. One of the several conceptual developments in this period refl ecting the possibility of mechanical replication is a view of the relationship of eternity to durational time based on Gregory of Nyssa’s philosophy of time and William of Ockham’s. Th e article considers how changes in these ideas helped enable the conceptual possibilities of the dissemination (...) of ideas. It describes a direct connection of human perceptual knowledge to divine knowledge that enhanced the authority of printed production to transfer and reproduce the true and the good. (shrink)

ExcerptThe French political theorist George Sorel repeatedly prophesied that Europe would provide the future soil of armed cataclysms.1 Furthermore, he claimed that the catalyzing factors for the conflicts of political power that lay behind such eruptions of violence and anarchy were myths, conceived not in the anthropological sense but as a series of images formed into a dramatic narrative capable of mobilizing social movements and inspiring violence to change the status quo. Thomas Mann lent weight to such an analysis when (...) he predicted that “in the era of the masses, parliamentary discussion would necessarily prove utterly inadequate as a means of shaping political will.” Thus, “in the future what was needed in its place were mythic fictions, which would be fed to the masses as the primitive battle cries necessary for unleashing and activating political energies.” Henceforth “popular myths, or better, myths trimmed for the masses, would be the vehicle of political action—fables, chimeras, phantasms that needed to have nothing whatever to do with truth, reason, or science in order to be productive nonetheless.”.

This new nonexistence of the Très Riches Heures is, I would argue, crucial to the existence of its replications. It is essential for each numbered copy of the limited facsimile edition that the original manuscript not be available for all to see. Most art historians, no matter how "contextual" or theoretical, would still emphasize the necessity of looking at the objects they study with that oddly singular, egocentrically well-trained "eye"/I. Left, however, with only the piles of reproductions I am forced (...) to ask myself and my students not what is the Très Riches Heures but what are the books, pamphlets, postcards, facsimiles, and the laser discs that scholars working on the manuscript at Chantilly are now shown instead of the original? The manuscript now has the status of one of those hypothetical "lost prototypes," beloved of scholars of manuscript illumination, that can only be seen refracted in its subsequent copies. Just as hypothesizing on the influence of early medieval "lost models" on existing works has always seemed to me a futile approach to medieval book painting, and preferring to view every manuscript as an object in its own right, I am not concerned with the lost and now forever invisible Très Riches Heures itself but rather with the power of its many reproductions. Michael Camille is associate professor of art history at the University of Chicago and the author of The Gothic Idol: Ideology and Image- Making in Medieval Art . He is working on a study of medieval marginal images entitled Image on the Edge. (shrink)

Sociologists, philosophers and historians of science are gradually recognizing the importance of visual representation. This is part of a more general movement away from a theory-centric view of science and towards an interest in practical aspects of observation and experimentation. Rather than treating science as a matter of demonstrating the logical connection between theoretical and empirical statements, an increasing number of investigations are examining how scientists compose and use diagrams, graphs, photographs, micrographs, maps, charts, and related visual displays. This paper (...) focuses on diagrams in biology, and tries to demonstrate how diagrams are an integral part of the production of scientific knowledge. In order to disclose some of the distinctive practical and analytical uses of diagrams, the paper contrasts the way diagrams and photographs are used in biological texts. Both diagrams and photographs are shown to be “constructions” that separately and together mediate the investigation of scientific phenoman. (shrink)

The ArgumentThe claim that Jan Swammerdam's empirical research did not support his theory of biological preformation is shown to rest on a notion of evidence narrower than that used by many seventeenth-century natural philosophers. The principles of evidence behind the use of mechanical models are developed. It is then shown that the Cartesian theory of biological reproduction and embryology failed to gain acceptance because it did not meet the evidential requirements of these principles. The problems in this and (...) other mechanistic theories prior to Swammerdam are found to arise from certain difficulties and tensions in the mechanical conception of nature, which Swammerdam's theory is able to resolve. The relation between Swammerdam's empirical research and his theory is examined and shown to satisfy the required notion of evidence.Leibniz' puzzling appeals to Swammerdam's research in support of his metaphysical doctrine of the spontaneous development of individual substances are then examined and shown to fall within the parameters of the notion of evidence.

The spatial-temporal association indicates that time is represented spatially along a left-to-right line. It is unclear whether the spatial-temporal association is mainly related to a perceptual or a motor component. In addition, the spatial-temporal association is not consistently found using a time reproduction task. Our rationale for this finding is that, classically, a non-lateralized button for performing the task has been used. Using two lateralized response buttons, the aim of the study was to find a spatial-temporal association in a (...) time reproduction task. To account for the perceptual component, reference and target stimuli were presented in different spaces through four experiments. In all experiments, a Spatial-Temporal Association of Response Codes (STEARC) effect was found and this effect was not modulated by the spatial position of both reference and target stimuli. The results suggested that the spatial-temporal association was mainly derived from the spatial information provided by response buttons, reflecting a motor but not visuospatial influence. (shrink)

L’universitarisation des formations au travail social est souvent pensée comme le remède à la reproduction tendancielle des savoirs et des pratiques dues à un système où domine fortement la formation par les pairs. Face à des transformations et des processus de réingénierie pédagogique s’étant développés dans le champ des formations au travail social, en France depuis les années 2010, comprenant notamment leur entrée dans le système européen des formations supérieures, et l’adjonction de matières académiques dans les parcours de formation, (...) il convient de s’interroger sur les enjeux et la portée d’une universitarisation qui en découlerait. Faute d’un cadrage théorique clair et de concepts permettant de penser l’action sociale d’accompagnement individuel et de transformation collective, les futurs travailleurs sociaux s’exposent aux dissonances cognitives. La sociologie d’intervention, entre autres disciplines, peut fournir les matériaux théoriques, conceptuels et méthodologiques de nature à éviter ces dissonances. (shrink)

In the contemporary context of increasing inequality and various forms of segregation, this volume analyzes the transition to neoliberal politics in Santiago de Chile. Using an innovative methodological approach that combines georeferenced data and multi-stage cluster analysis, Méndez and Gayo study the old and new mechanisms of social reproduction among the upper middle class. In so doing, they not only capture the interconnections between macro- and microsocial dimensions such as urban dynamics, schooling demands, cultural repertoires and socio-spatial trajectories, but (...) also offer a detailed account of elite formation, intergenerational accumulation, and economic, cultural, and social inheritance dynamics.

In most social species, position in the male social hierarchy and reproductive success are positively correlated; in humans, however, this relationship is less clear, with studies of traditional societies yielding mixed results. In the most economically advanced human populations, the adaptiveness of status vanishes altogether; social status and fertility are uncorrelated. These findings have been interpreted to suggest that evolutionary principles may not be appropriate for the explanation of human behavior, especially in modern environments. The present study tests the adaptiveness (...) of social status with actual mating and reproductive data in a representative sample of males from an industrial society. Reproductive success, even when assessed by a more reliable measure ofactualmale fertility than the one commonly used, fails to correlate with social status. In striking contrast, however, status is found to be highly correlated withpotentialfertility, as estimated from copulation frequency. Status thus accounts for as much as 62% of the variance in thisproximatecomponent of fitness. This pattern is remarkably similar to what is found in many traditional societies and would result in a substantial positive relationship between cultural and reproductive success in industrial populations were it not for the novel conditions imposed by contraception and monogamy. Various underlying mechanisms are suggested for these findings, illustrating the value of current behavioral and reproductive data in the study of adaptation. It is concluded that evolutionary explanations of human behavior remain entirely relevant in modern societies. (shrink)

A subcategory of medical tourism, reproductive tourism has been the subject of much public and policy debate in recent years. Specific concerns include: the exploitation of individuals and communities, access to needed health care services, fair allocation of limited resources, and the quality and safety of services provided by private clinics. To date, the focus of attention has been on the thriving medical and reproductive tourism sectors in Asia and Eastern Europe; there has been much less consideration given to more (...) recent ‘players’ in Latin America, notably fertility clinics in Chile, Brazil, Mexico and Argentina. In this paper, we examine the context-specific ethical and policy implications of private Argentinean fertility clinics that market reproductive services via the internet. Whether or not one agrees that reproductive services should be made available as consumer goods, the fact is that they are provided as such by private clinics around the world. We argue that basic national regulatory mechanisms are required in countries such as Argentina that are marketing fertility services to local and international publics. Specifically, regular oversight of all fertility clinics is essential to ensure that consumer information is accurate and that marketed services are safe and effective. It is in the best interests of consumers, health professionals and policy makers that the reproductive tourism industry adopts safe and responsible medical practices. (shrink)

Unlike Aristotelian physics with its teleological notions, modern physics was developed exclusively in relation to the nonliving domain. This raised the question as to whether mechanics applies to organisms, and if so, to what extent. From the seventeenth century on, mechanistic ideas became prominent in biological and medical theory. Contemporary biology explains essential features of life on the basis of physical laws and processes. This does not prove, however, that the early mechanists were essentially right. In the eighteenth century, following (...) Cartesian notions of mind-body separation and preformation theories of organismic development, they tended to exclude major biological questions rather than answering them. It was those who insisted on the organizational features of organisms, like Stahl and Wolff, who paved the way for solutions to such crucial problems as the psychological basis of human nature and behavior and the generation of form in the course of reproduction. Though they underrated the potentials of a future, extended physics for understanding biology, their case against reductionist exclusion should not be considered outdated even today. (shrink)

It is commonly assumed that the desire for a thin female physique and its pathological expression in eating disorders result from a social pressure for thinness. However, such widespread behavior may be better understood not merely as the result of arbitrary social pressure, but as an exaggerated expression of behavior that may have once been adaptive. The reproductive suppression hypothesis suggests that natural selection shaped a mechanism for adjusting female reproduction to socioecological conditions by altering the amount of body (...) fat. In modern Western culture, social and ecological cues, which would have signaled the need for temporary postponement of reproduction in ancestral environments, may now be experienced to an unprecedented intensity and duration.

Discovery of a second, inducible prostaglandin synthase provides explanations for many previously puzzling observations, but also raises new questions about prostanoid synthesis. A cis‐acting sequence closely related to the cyclic AMP response element has been shown to play a role in both basal and induced prostaglandin synthase 2 gene expression. Aspirin and other currently available non‐steroidal anti‐inflammatory drugs that inhibit prostaglandin synthase activity do not effectively discriminate between the inducible prostaglandin synthase 2 and constitutive prostaglandin synthase 1 enzymes. Identification of (...) a second prostaglandin synthase, induced by inflammatory stimuli, initiated a search for isoform‐specific inhibitors. Use of prostaglandin synthase 2 specific inhibitors and antisense oligonucleotides has led to the suggestion that specific ligands activate alternative pathways of prostanoid production, using one of the prostaglandin synthase isoforms preferentially. The coupling mechanisms by which these pathways are activated in response to alternative stimuli should provide additional routes of intervention in prostanoid production. (shrink)

The article is dedicated to one of the fundamental social problems – the problem of inequality in the field of education and the mechanisms of its reproduction. The author's view of the problem is related to understanding the evolution of the institute of education in the light of the accompanying scientific discourse, which usually starts with the issue of equal access to educational resources, and then emphasizes on discussing the possibilities for equality of educational outcomes. The author traces several (...) main stages that reveal the progressive movement of the institutional nature of education, especially in the direction of expanding its accessibility, openness and efficiency, which at the same time remains firmly embedded in the existing system of stratification. Attention is paid mainly to the analysis of the way in which the institutional instruments in the form of selection and differentiation are materialized in the complex mechanisms and realities of the pedagogical process and contribute to the exacerbation of educational inequalities.

This paper aims to investigate the kinaesthetic experience of dance, and especially of pantomime dance in Lucian’s De Saltatione and in Libanius’ oration 64, A Reply To Aristides On Behalf Of The Dancers, from the perspective of the mechanical. Specifically, pantomime will be discussed in juxtaposition with the concept of mechanical automation. Until now, this aspect remains unexplored; however, this is of great importance, particularly if we take into consideration that from the Hellenistic period onwards theatrical automata and (...) processions with engineered artefacts were considered to be a popular entertainmentmechanism and, as such, they exerted great influence on the public’s aesthetic. In this respect, I intend first to survey the concept of pantomimic mimesis as a mechanical reproduction of motion, i.e. gestures and postures. Next, I shall detect the vocabulary of mechanisms/mechanisms’ function that is generally embedded in dance rhetoric by examining forced motion both in pantomime and ancient mechanics. (shrink)

The female reproductive axis in mammals is a highly complex dynamic system which goes through different transient or absorbent states during the course of a life-time. Little is known about the mechanisms controlling this system during fetal life and at birth, although it has been shown in numerous species, including primates, that the whole machinery is already functioning . After a delay ranging from a few days to a few weeks, according to the species, the reproductive axis becomes quiescent and (...) activity apparently resumes only at the time of puberty. Here again understanding of the phenomenon is still limited. (shrink)

The dynamics of populations of self-replicating, hierarchically structured individuals, exposedto accidents which destroy their sub-units, is analyzed mathematically, specifically with regardto the roles of redundancy and sexual repair. The following points emerge from this analysis:0 A population of individuals with redundant sub-structure has no intrinsic steady-statepoint; it tends to either zero or infinity depending on a critical accident rate α c . Increased redundancy renders populations less accident prone initially, but populationdecline is steeper if a is greater than a fixed (...) value α d . Periodic, sexual repair at system-specific intervals prevents continuous decline and stabilizesthe population insofar as it will now oscillate between two fixed population levels. The stabilizing sexual interval increases with increased complexity provided this is accom-panied by appropriate levels of redundancy. The model closely simulates the dynamics of heterosis effects. Repair fitness is a population fitness: the chance of an individual being repaired is a functionof the statistical make-up of the population as a whole at that particular period. Populationsliving at α > α c either engage in sexual repair at the appropriate time or they die out. The mathematical properties of the model illustrate mechanisms which possibly played arole in the evolution of a mortal soma in relation to sexual reproduction. (shrink)

SummaryThe recent years have seen a surge in elite athlete activism. This article examines how Olympic athletes are currently challenging the stability of central institutions of the Olympic Movement as collective political actors. The study builds on explanations of stability and change stemming from punctuated equilibrium theory and path dependency. Applying a multiple mini case study design, it is first illustrated how these mechanisms have been in play in the reproduction and disruption of historic Olympic institutions. The main analysis (...) then shows how Olympic athletes, through their different organizational forms, challenge institutions that are detrimental to their interest. The findings illustrate that Olympic athletes have increased their power resources and apply strategies to defy institutions, which are reproduced on the basis of path-dependent explanations. In doing so, athletes have the potential to severely destabilize the system if their interests remain unaccounted for by those governing the Olympic Movement. (shrink)

In this paper I address an important question in Aristotle’s biology, What are the causal mechanisms behind the transmission of biological form? Aristotle’s answer to this question, I argue, is found in Generation of Animals Book 4 in connection with his investigation into the phenomenon of inheritance. There we are told that an organism’s reproductive material contains a set of "movements" which are derived from the various "potentials" of its nature (the internal principle of change that initiates and controls development). (...) These movements, I suggest, function as specialized vehicles for communicating the parts of the parent’s heritable form during the act of reproduction. After exploring the details of this mechanism, I then take up Aristotle’s theory of inheritance proper. At the heart of the theory are three general principles (or 'laws') that govern the interactions between the maternal and paternal movements, the outcome of which determines the pattern of inheritance for the offspring. Although this paper is primarily aimed at providing a detailed analysis of Aristotle’s account of inheritance, the results of that analysis have implications for other areas of Aristotle’s biology. One of the most interesting of these is the question of whether Aristotle’s biology is anti-evolutionary (as traditionally assumed) or whether (as I argue) it leaves room for a theory of evolution by natural selection, even if Aristotle himself never took that step.

It is widely accepted that stressful conditions can facilitate evolutionary change. The mechanisms elucidated thus far accomplish this with a generic increase in heritable variation that facilitates more rapid adaptive evolution, often via plastic modifications of existing characters. Through scrutiny of different meanings of stress in biological research, and an explicit recognition that stressors must be characterized relative to their effect on capacities for maintaining functional integrity, we distinguish between: (1) previously identified stress-responsive mechanisms that facilitate evolution by maintaining an (...) adaptive fit with the environment, and (2) the co-option of stress-responsive mechanisms that are specific to stressors leading to the origin of novelties via compensation. Unlike standard accounts of gene co-option that identify component sources of evolutionary change, our model documents the cost-benefit trade-offs and thereby explains how one mechanism—an immediate response to acute stress—is transformed evolutionarily into another—routine protection from recurring stressors. We illustrate our argument with examples from cell type origination as well as processes and structures at higher levels of organization. These examples suggest a general principle of evolutionary origination based on the capacity to switch between regulatory states related to reproduction and proliferation versus survival and differentiation.

Observing the practical situation of the techniques of assisted procreation in European societies, one is allowed to affirm that these techniques are largely in use in our societies, it did not find resistance among the secular groups of the society.

However, they could not oppose the scientific and medical corporation and their arguments of treatment of diseases and of sterility of men or women. This way to present these reproductive techniques in terms of lowering of suffering of couples not able to reproduce naturally received a full social acceptance and legitimation, acceptation because the origin of these techniques is incontestably scientific and legitimation because the goal is essentially medical.

From the mid-nineteenth century to the Gilded Age, Catharine Beecher and other American social reformers combined natural theology and evangelism to instruct their audiences how to lead healthy, virtuous, and happy lives. Worried about the consequences of urbanization, industrialization, unstable sexual and gender roles, and immigration, these “Christian physiologists” provided prescriptive scientific advice for hygiene and personal conduct based on the traditional norms of white, middle-class, Protestant domesticity. According to Beecher and her counterparts, the biosocial reproduction of ideal American (...) households promised to reverse the degeneration of men and women across the country and to ensure the long-term vitality of their children. Using evidence from Beecher, Harriet Beecher Stowe, Charlotte Perkins Gilman, and other nineteenth-century writers, I investigate the methods and aims of Christian physiology along with its relationships to natural theology, Darwinian feminism, and other reform movements. I also analyze how Beecher and her successors employed concepts including the machine, the tissue, the cell, and the germ to justify their conclusions about the optimal structure and functions of American society. Overall, I demonstrate how these actors leveraged the body and the family as mechanisms to produce healthy parents, children, and communities for an ailing nation. (shrink)

Since the 1970s, prenatal testing has been integrated into many health care systems on the basis of two competing and largely irreconcilable rationales. The reproductive autonomy rationale focuses on nondirective counseling and consent as ways to ensure that women's decisions about testing and subsequent care are informed and free of undue pressures. It also represents an easily understandable and ethically convincing basis for widespread access to prenatal testing, since the value of autonomy is well established in Western bioethics and widely (...) recognized by funders of health care. In contrast, the public health rationale approaches prenatal testing as designed to reduce the incidence of certain conditions in the population to reduce the burden of disease. This rationale emphasizes the societal consequences of reproduction and the aggregate impact of women's individual reproductive decisions on the overall health of future populations. In this essay, I argue that, despite what could be seen as a persistent failure to meet the ideals of reproductive autonomy, resisting the public health rationale as a basis for prenatal screening is ethically and pragmatically crucial. I recommend policy mechanisms that can enhance reproductive autonomy at a societal level to support choice at the individual level. (shrink)

An extended period of childhood and juvenility is a distinctive aspect of human life history. This stage appears to be important for learning cultural, social, and ecological skills that help prepare the child for the adult socio-competitive environment. The unusual pattern of adrenarche in humans (and chimpanzees) may facilitate adaptive modification of the neurobiological mechanisms that underpin reproductive strategies. Longitudinal monitoring of DHEA/S in naturalistic context could provide important new insights into these aspects of child development.

Darwinian evolution can be simply stated: natural selection of inherited variations increasing differential reproduction. However, formulated thus, links with biochemistry, cell biology, ecology, and population dynamics remain unclear. To understand interactive contributions of chance and selection, higher levels of biological organization (e.g., endosymbiosis), complexities of competing selection forces, and emerging biological novelties (such as eukaryotes or meiotic sex), we must analyze actual examples. Focusing on mitochondria, I will illuminate how biology makes sense of life's evolution, and the concepts involved. (...) First, looking at the bacterium – mitochondrion transition: merging with an archaeon, it lost its independence, but played a decisive role in eukaryogenesis, as an extremely efficient aerobic ATP generator and internal ROS source. Second, surveying later mitochondrion adaptations and diversifications illustrates concepts such as constructive neutral evolution, dynamic interactions between endosymbionts and hosts, the contingency of life histories, and metabolic reprogramming. Without oxygen, mitochondria disappear; with (intermittent) oxygen diversification occurs in highly complex ways, especially upon (temporary) phototrophic substrate supply. These expositions show the Darwinian model to be a highly fruitful paradigm. (shrink)

Over the last two decades, social scientists across disciplines have been researching how value is extracted and governed in the reproductive bioeconomy, which broadly refers to the various ways reproductive tissues, bodies, services, customers, workers, and data are inserted into capitalist modes of accumulation. While many of these studies are empirically grounded in single country–based analyses, this paper proposes an integrative political economy framework, structured around the concept of “global fertility chains.” The latter articulates the reproductive bioeconomy as a nexus (...) of intraconnected practices, operations, and transactions between enterprises, states, and households across the globe, through which reproductive services and commodities are produced, distributed, and consumed. Employing a diffractive reading of the literature on commodity chains and care chains, this unified approach scrutinizes the coproduction of value, biology, and technoscience and their governance mechanisms in the accumulation of capital by taking into account the unevenly developed geographies of global fertility chains, their reliance on women’s waged and unwaged reproductive labor, and the networked role of multiple actors at multiple scales without losing sight of the constitutive role of national states in creating demand, organizing supply, and accommodating the distribution of surplus value. We empirically ground this integrative political economy approach of the reproductive bioeconomy through collaborative, multisited fieldwork on transnational reproduction networks in Israel/palestine, Romania, Georgia, and Spain.

Reproductive proteins maintain species‐specific barriers to fertilization, affect the outcome of sperm competition, mediate reproductive conflicts between the sexes, and potentially contribute to the formation of new species. However, the specific proteins and molecular mechanisms that underlie these processes are understood in only a handful of cases. Advances in genomic and proteomic technologies enable the identification of large suites of reproductive proteins, making it possible to dissect reproductive phenotypes at the molecular level. We first review these technological advances and describe (...) how reproductive proteins are identified in diverse animal taxa. We then discuss the dynamic evolution of reproductive proteins and the potential selective forces that act on them. Finally, we describe molecular and genomic tools for functional analysis and detail how evolutionary data may be used to make predictions about interactions among reproductive proteins. (shrink)

Feminist investigations into caring technologies emphasise the tension between their reproduction of care’s assumed femininity and their ability to destabilise gendered markers and systems. However, the existing literature ignores the historical racialisation of care and its perpetuation in the form of the posthuman caring object. This article examines how racialised relations of power shape the posthumanisation of care in three science-fiction works, Channel 4’s television show Humans (2015), Alex Riviera’s film Sleep Dealer (2008) and Spike Jonze’s film Her (2013). (...) While Her’s disembodied operating systems are premised upon an implicit whiteness, posthuman caring objects in Humans and Sleep Dealer take a racialised, embodied form. Drawing upon the work of Saidiya Hartman and Fred Moten, this article examines how the racialised objects in Humans and Sleep Dealer are constituted as both labourers and commodities, purchased for the purpose of facilitating white reproductivity. Nonetheless, this article also documents how these caring technologies complicate key binaries such as subject/object, human/machine and productive/reproductive labour. In doing so, they disrupt the whiteness of the social reproduction paradigm. The article concludes by calling for greater feminist engagement with the racialisation of care labour in human and posthuman forms, in order to challenge white, heterosexual models of reproductivity based upon the exploitation of racialised labour.

Philosophy's only celebration of photography's 150th, the long-neglected philosophical job of clarification: drawing basic distinctions and defining basic conceptions, including photographic depiction, photographic detection, 'photograph of', 'documentary'. More than a lexicon, it explains why photography is important, by historically characterizing it through its uses for depiction, detection, reproduction, all of which have shaped the modern world. By consideration of it as 'mechanical', the paper explains photography's differences from practices with which it shares these functions. Happy birthday, photography.
