While scholars have examined how cosmetic surgery can reinforce gender norms, the development of racially specific standards is a more recent phenomenon that has received less scrutiny. This article examines how cosmetic surgeons conceptualize race and its intersection with gender. Through analysis of eighty surgeon-authored procedural guides, I find that surgeons engage in what I term the biological construction of social difference, mixing discourses of biology and physical difference with social and cultural discourses to describe patient beauty ideals. Surgeons develop an expert discourse on race and gender that is simultaneously about difference and beauty. The development of “ethnic” specific cosmetic surgery standards enshrines a “white” default referent even as it opens the door to other configurations of physical appearance. Cosmetic surgery implies that physical markers of race and gender are mutable – literally, via the surgeon’s scalpel – even as it relies on and reinforces established notions of racial difference.  相似文献

We set out an account of how self-domestication plays a crucial role in the evolution of language. In doing so, we focus on the growing body of work that treats language structure as emerging from the process of cultural transmission. We argue that a full recognition of the importance of cultural transmission fundamentally changes the kind of questions we should be asking regarding the biological basis of language structure. If we think of language structure as reflecting an accumulated set of changes in our genome, then we might ask something like, “What are the genetic bases of language structure and why were they selected?” However, if cultural evolution can account for language structure, then this question no longer applies. Instead, we face the task of accounting for the origin of the traits that enabled that process of structure-creating cultural evolution to get started in the first place. In light of work on cultural evolution, then, the new question for biological evolution becomes, “How did those precursor traits evolve?” We identify two key precursor traits: (1) the transmission of the communication system through learning; and (2) the ability to infer the communicative intent associated with a signal or action. We then describe two comparative case studies—the Bengalese finch and the domestic dog—in which parallel traits can be seen emerging following domestication. Finally, we turn to the role of domestication in human evolution. We argue that the cultural evolution of language structure has its origin in an earlier process of self-domestication.  相似文献

Attempts to investigate the drivers of invasion success are generally limited to the biological and evolutionary traits distinguishing native from introduced species. Although alien species introduced to the same recipient environment differ in their invasion intensity – for example, some are “strong invaders”; others are “weak invaders” – the factors underlying the variation in invasion success within alien communities are little explored. In this study, we ask what drives the variation in invasion success of alien mammals in South Africa. First, we tested for taxonomic and phylogenetic signal in invasion intensity. Second, we reconstructed predictive models of the variation in invasion intensity among alien mammals using the generalized linear mixed‐effects models. We found that the family Bovidae and the order Artiodactyla contained more “strong invaders” than expected by chance, and that such taxonomic signal did not translate into phylogenetic selectivity. In addition, our study indicates that latitude, gestation length, social group size, and human population density are only marginal determinant of the variation in invasion success. However, we found that evolutionary distinctiveness – a parameter characterising the uniqueness of each alien species – is the most important predictive variable. Our results indicate that the invasive behavior of alien mammals may have been “fingerprinted” in their evolutionary past, and that evolutionary history might capture beyond ecological, biological and life‐history traits usually prioritized in predictive modeling of invasion success. These findings have applicability to the management of alien mammals in South Africa.  相似文献

Despite a growing personal genomics market, little is known about how people engage with the possibilities offered by direct-to-consumer (DTC) genetic testing. In order to help address this gap, this study deploys narrative analysis of YouTube videos posted by individuals who have purchased DTC genetic testing for disease. Genetic testing is said to be contributing to new states of illness, where individuals may become “patients-in-waiting.” In the videos analyzed, we found a new form of storytelling about this ambiguous state of illness, which we refer to as autobiology. Autobiology – the study of, and story about, one's own biology – concerns narratives of sense-making through forms of biological practice, as well as wayfaring narratives which interweave genetic markers and family histories of disease. These autobiologies – part of a broader shift toward public stories about genetics and other healthcare technologies – exhibit playfulness, as well as being bound with consumerist practices.  相似文献

One of the main challenges when integrating biological and social perspectives in primatology is overcoming interdisciplinary barriers. Unfamiliarity with subject-specific theory and language, distinct disciplinary-bound approaches to research, and academic boundaries aimed at “preserving the integrity” of subject disciplines can hinder developments in interdisciplinary research. With growing interest in how humans and other primates share landscapes, and recognition of the importance of combining biological and social information to do this effectively, the disparate use of terminology is becoming more evident. To tackle this problem, we dissect the meaning of what the biological sciences term studies in “human–wildlife conflict” or more recently “human–wildlife interactions” and compare it to what anthropology terms “multispecies ethnography.” In the biological sciences, human–wildlife interactions are the actions resulting from people and wild animals sharing landscapes and resources, with outcomes ranging from being beneficial or harmful to one or both species. In the social sciences, human–nonhuman relationships have been explored on a philosophical, analytical, and empirical level. Building on previous work, we advocate viewing landscapes through an interdisciplinary “multispecies lens” in which humans are observed as one of multiple organisms that interact with other species to shape and create environments. To illustrate these interconnections we use the case study of coexistence between people of the Nalu ethnic group and Critically Endangered western chimpanzees (Pan troglodytes verus) at Cantanhez National Park in Guinea-Bissau, to demonstrate how biological and social research approaches can be complementary and can inform conservation initiatives at the human–primate interface. Finally, we discuss how combining perspectives from ethnoprimatology with those from multispecies ethnography can advance the study of ethnoprimatology to aid productive discourse and enhance future interdisciplinary research.  相似文献

In May 2011, the International Alliance for Biological Standardization, with the cooperation of WHO, FDA, and NIAID, organized a conference on adventitious agents that might be found in biological products using new technology (http://www.iabs.org/index.php/past-conference-reports/116-baltimore-2011-slides). The implications of such findings on risk assessment also were considered. Topics that were addressed included: a) current routine testing – what are we doing now?; b) recent advances in testing – what tests are being explored/applied?; c) examples of finding agents with “new” techniques; and d) risk assessment, including recent WHO activities. A draft algorithm for risk assessment was discussed in terms of its applicability to a variety of potential new agents and the possibilities for improving it.  相似文献

Between 1946 and 1960, a new phenomenon emerged in the field of bacteriology. “Bacterial sex,” as it was called, revolutionized the study of genetics, largely by making available a whole new class of cheap, fast-growing, and easily manipulated organisms. But what was “bacterial sex?” How could single-celled organisms have “sex” or even be sexually differentiated? The technical language used in the scientific press – the public and inalienable face of 20th century science – to describe this apparently neuter organism was explicit: the cells “copulated,” had “intimate contract,” “conjugal unions,” and engaged in “ménage ã trois” relationships. And yet, to describe bacteria as sexually reproducing organisms, the definition of sex itself had to change. Despite manifold contradictions and the availability of alternative language, the notion of sexually active (even promiscuous) single-celled organisms has persisted, even into contemporary textbooks on cell biology and genetics. In this paper I examine the ways in which bacteria were brought into the genetic fold, sexualized, and given gender; I also consider the issues underlying the durability of “bacterial sex.”  相似文献

Immigration has dramatically changed the face of the nation in the last thirty years, yet it is unclear how children currently define “Americanness” in light of these demographic and cultural shifts. This research explores how elementary students define what it means to be American in the context of immigration-driven diversity. Based on a survey of fourth and fifth graders in an elementary school located in a high-immigrant community, the author shows that despite the diversity of the school and local surroundings, and the multicultural ideology espoused by school staff, students predominately defined “American” in ethnocultural terms – specifically, as white, US-born, and English-speaking. At the same time, a small group of students challenged this narrative and defined Americans in pluralist terms. This study suggests that schools aiming to create inclusive learning communities in an increasingly diverse nation may need more direct approaches to teaching a culturally pluralist model of America.  相似文献

All social species face various “collective action problems” (CAPs) or “social dilemmas,” meaning problems in achieving cooperating when the best move from a selfish point of view yields an inferior collective outcome. Compared to most other species, humans are very good at solving these challenges, suggesting that something rather peculiar about human sociality facilitates collective action. This article proposes that language — the uniquely human faculty of symbolic communication — fundamentally alters the possibilities for collective action. I explore these issues using simple game-theoretic models and empirical evidence (both ethnographic and experimental). I review several standard mechanisms for the evolution of cooperation — mutualism, reciprocal altruism, indirect reciprocity and signaling — highlighting their limitations when it comes to explaining large-group cooperation, as well as the ways in which language helps overcome those limitations. Language facilitates complex coordination and is essential for establishing norms governing production efforts and distribution of collective goods that motivate people to cooperate voluntarily in large groups. Language also significantly lowers the cost of detecting and punishing “free riders,” thus greatly enhancing the scope and power of standard conditional reciprocity. In addition, symbolic communication encourages new forms of collectively beneficial displays and reputation management — what evolutionists often term “signaling” and “indirect reciprocity.” Thus, language reinforces existing forces that favor the evolution of cooperation, as well as creating new opportunities for collective action not available even to our closest primate relatives.  相似文献

The epigenetic “revolution” in science cuts across many disciplines, and it is now one of the fastest-growing research areas in biology. Increasingly, claims are made that epigenetics research represents a move away from the genetic determinism that has been prominent both in biological research and in understandings of the impact of biology on society. We discuss to what extent an epigenetic framework actually supports these claims. We show that, in contrast to the received view, epigenetics research is often couched in language as deterministic as genetics research in both science and the popular press. We engage the rapidly emerging conversation about the impact of epigenetics on public discourse and scientific practice, and we contend that the notion of epigenetic determinism – or the belief that epigenetic mechanisms determine the expression of human traits and behaviors – matters for understandings of the influence of biology and society on population health.  相似文献

One of the most frequently advanced explanations of the Maoists’ popularity in rural Nepal links dissatisfaction with the State to forms of consciousness and changes in expectations that are products and processes of development. Such theories often attribute popular support for the insurrection to frustrated desires stemming from “failed” or “incomplete” development. Against this, others suggest that it was the very “success” of empowerment programs which aimed to raise participants’ consciousness of oppression and its roots that inspired villagers to embrace revolutionary action. This paper argues that, despite their differences, both hypotheses reflect assumptions about gendered selfhood and political action that limit their recognition of what motivates Maoist sympathies. Extended research with women in Gorkha—a district where female support for the rebels is said to be especially strong—reveals that Gorkhali women’s support for the rebels is not inspired primarily by the desire for greater autonomy, choice or absolute liberation from social constraints, all of which ideals valorize a culturally specific vision of individual agency. Rather, women there report a sense of self that defines itself through social relations and commitments and which values the common good over individual self-interest, which they associate with an unjust state. The disjuncture between Gorkhali women’s own understandings of self and society and prevailing theories of what motivates people to rebel highlights the modernist assumptions that underlie—and potentially distort—otherwise diverse scholarly perspectives. Likewise, it implies that rebellions may be less about consciousness and more about morality than either “failed” or “successful” theories presume.  相似文献

Genomics is increasingly considered a global enterprise – the fact that biological information can flow rapidly around the planet is taken to be important to what genomics is and what it can achieve. However, the large-scale international circulation of nucleotide sequence information did not begin with the Human Genome Project. Efforts to formalize and institutionalize the circulation of sequence information emerged concurrently with the development of centralized facilities for collecting that information. That is, the very first databases build for collecting and sharing DNA sequence information were, from their outset, international collaborative enterprises. This paper describes the origins of the International Nucleotide Sequence Database Collaboration between GenBank in the United States, the European Molecular Biology Laboratory Databank, and the DNA Database of Japan. The technical and social groundwork for the international exchange of nucleotide sequences created the conditions of possibility for imagining nucleotide sequences (and subsequently genomes) as a “global” objects. The “transnationalism” of nucleotide sequence was critical to their ontology – what DNA sequences came to be during the Human Genome Project was deeply influenced by international exchange.  相似文献

Biologists of the late eighteenth and early nineteenth centuries all bandied about the term “species,” but very rarely actually said what they meant by it. Often, however, one can get inside their thinking by piecing together some of their remarks. One of the most nearly explicit‐appropriately, for the man who wrote a book called The Origin of Species – was Charles Darwin 1 : “Practically, when a naturalist can unite two forms together by others having intermediate characters, he treats the one as a variety of the other… He later translated this into evolutionary terms: “Hereafter, we shall be compelled to acknowledge that the only distinction between species and well‐marked varieties is, that the latter are known, or believed, to be connected at the present day by intermediate gradations, whereas species were formerly thus connected”1:484‐5  相似文献

Could exogenous genes from another biosphere have aided the evolution of life on Earth's surface over the last half-billion years? That possibility was considered by Thomas Gold in 1992, when he hypothesized that a “deep hot biosphere” (DHB) resides independently well below its cooler surface counterpart. And he suggested that “… in the long term … there may occasionally be beneficial exchanges of genetic material between microbial life at depth and the surface life.” Thus, the question: what evidence is there to support Gold's notion that exogenous genes from the DHB – let us call them “bioplutons” – ever bestowed benefits on the evolution of surface life? In pursuit of this question I drafted a null hypothesis: “Nothing beyond our own biosphere, as we know it today, renders any kind of genetic benefits to biological evolution.” After objectively analyzing the evidence and arguments pro and con I failed to reject the null hypothesis, given what we know today, especially the fact that no genetic imprint from the DHB has been identified in eukaryotic genomes. But my conclusion is regarded as tentative, because the fundamentals of Gold's argument, collectively referred to herein as “bioplutonism,” might be confirmed eventually with successful probes into the DHB, and with the sampling of its alleged genetic material.  相似文献

The dynamic instability of living systems and the “superposition” of different forms of randomness are viewed, in this paper, as components of the contingently changing, or even increasing, organization of life through ontogenesis or evolution. To this purpose, we first survey how classical and quantum physics define randomness differently. We then discuss why this requires, in our view, an enriched understanding of the effects of their concurrent presence in biological systems’ dynamics. Biological randomness is then presented not only as an essential component of the heterogeneous determination and intrinsic unpredictability proper to life phenomena, due to the nesting of, and interaction between many levels of organization, but also as a key component of its structural stability. We will note as well that increasing organization, while increasing “order”, induces growing disorder, not only by energy dispersal effects, but also by increasing variability and differentiation. Finally, we discuss the cooperation between diverse components in biological networks; this cooperation implies the presence of constraints due to the particular nature of bio-entanglement and bio-resonance, two notions to be reviewed and defined in the paper.  相似文献

Dr. Alice Stewart conclusively demonstrated, in 1958, that pediatric X‐rays doubled the risk of childhood leukemia. Nevertheless, doctors continued X‐raying mothers‐to‐be until 1980. Margaret Heffernan's (2011) book, Willful Blindness: Why We Ignore the Obvious at Our Peril, documents this and numerous other examples of our skill at ignoring information that points to something we don't want to know. Specifically, on the topic of climate change, Heffernan notes: “[I]n failing to confront the greatest challenge of our age – climate change – all the forces of willful blindness come together, like synchronized swimmers in a spectacular water ballet.” When it comes to corporate sustainability, we're seeing some recent efforts to get past willful blindness. In 2013, we saw examples such as Auden Schendler (co‐author of this piece) and Michael Toffel's (2013) publication in Grist, Corporate Sustainability is Not Sustainable, which itself built upon Professor Robin Craig's (2012) article provocatively entitled “Climate Change Means the Death of Sustainability.” More recently, in Lima, Unilever's Paul Polman said that “.. most CEOs…know that their companies cannot prosper in a world with runaway climate change.” Perhaps, after years of corporate sustainability flag waving, it is no longer possible to ignore the fact that much of what companies classify as “sustainability” is, at best, green fluff that is fundamentally out of touch with the realities of anticipated climate change. Significantly, chief executive officers (CEOs) themselves are questioning the historic focus on corporate sustainability policies and targets. As summarized in the CEO Study on Sustainability, jointly published by the United Nations (UN) Global Compact and Accenture (2013): “Business leaders [now] believe that only with greater government intervention — at global, national and local levels — can sustainability move from sporadic incremental advances to a collective and transformative impact.”  相似文献

In recent years, there has been growing awareness among evolutionary ethicists that systems of cooperation based upon “weak” reciprocity mechanisms (such as tit-for-tat) lack scalability, and are therefore inadequate to explain human ultrasociality. This has produced a shift toward models that strengthen the cooperative mechanism, by adding various forms of commitment or punishment. Unfortunately, the most prominent versions of this hypothesis wind up positing a discredited mechanism as the basis of human ultrasociality, viz. a “greenbeard.” This paper begins by explaining what a greenbeard is, and why evolutionary theorists are doubtful that such a mechanism could play a significant role in explaining human prosociality. It goes on to analyze several recent philosophical works in evolutionary ethics, in order to show how the suggestion that morality acts as a commitment device tacitly relies upon a greenbeard mechanism to explain human cooperation. It concludes by showing how some early scientific models in the “evolution of cooperation” literature, which introduced punishment as a device to enhance cooperation, also tacitly relied upon a greenbeard mechanism.  相似文献

We present a general model of why “thinking a lot” is a key presentation of distress in many cultures and examine how “thinking a lot” plays out in the Cambodian cultural context. We argue that the complaint of “thinking a lot” indicates the presence of a certain causal network of psychopathology that is found across cultures, but that this causal network is localized in profound ways. We show, using a Cambodian example, that examining “thinking a lot” in a cultural context is a key way of investigating the local bio-cultural ontology of psychopathology. Among Cambodian refugees, a typical episode of “thinking a lot” begins with ruminative-type negative cognitions, in particular worry and depressive thoughts. Next these negative cognitions may induce mental symptoms (e.g., poor concentration, forgetfulness, and “zoning out”) and somatic symptoms (e.g., migraine headache, migraine-like blurry vision such as scintillating scotomas, dizziness, palpitations). Subsequently the very fact of “thinking a lot” and the induced symptoms may give rise to multiple catastrophic cognitions. Soon, as distress escalates, in a kind of looping, other negative cognitions such as trauma memories may be triggered. All these processes are highly shaped by the Cambodian socio-cultural context. The article shows that Cambodian trauma survivors have a locally specific illness reality that centers on dynamic episodes of “thinking a lot,” or on what might be called the “thinking a lot” causal network.  相似文献

Understanding how cooperation evolves is central to explaining some core features of our biological world. Many important evolutionary events, such as the arrival of multicellularity or the origins of eusociality, are cooperative ventures between formerly solitary individuals. Explanations of the evolution of cooperation have primarily involved showing how cooperation can be maintained in the face of free-riding individuals whose success gradually undermines cooperation. In this paper I argue that there is a second, distinct, and less well explored, problem of cooperation that I call the generation of benefit. Focusing on how benefit is generated within a group poses a different problem: how is it that individuals in a group can (at least in principle) do better than those who remain solitary? I present several different ways that benefit may be generated, each with different implications for how cooperation might be initiated, how it might further evolve, and how it might interact with different ways of maintaining cooperation. I argue that in some cases of cooperation, the most important underlying “problem” of cooperation may be how to generate benefit, rather than how to reduce conflict or prevent free-riding.  相似文献
