Understanding how complex sexual reproduction arose, and why sexual organisms have been more successful than otherwise similar asexual organisms, is a longstanding problem in evolutionary biology. Within this problem, the potential role of endosymbionts or intracellular pathogens in mediating primitive genetic transfers is a continuing theme. In recent years, several remarkable activities of mitochondria have been observed in the germline cells of complex eukaryotes, and it has been found that bacterial endosymbionts related to mitochondria are capable of manipulating diverse aspects (...) of metazoan gametogenesis. An attempt is made here to rationalize these observations with an endosymbiotic model for the evolutionary origins of sex. It is hypothesized that the contemporary life cycle of germline cells has descended from the life cycle of the endosymbiotic ancestor of the mitochondrion. Through an actin‐based motility that drove it from one cell to another, the rickettsial ancestor of mitochondria may have functioned as a primitive transducing particle, the evolutionary progenitor of sperm.

The ultimate causes of sex differences in human aggressive behavior can lie mainly in evolved, inherited mechanisms that differ by sex or mainly in the differing placement of women and men in the social structure. The present commentary contrasts Campbell's evolutionary interpretation of aggression sex differences with a social structural interpretation that encompasses a wider range of phenomena.

In spite of the fact that the term ‘sexology’ was popularized in the United States by Elizabeth Osgood Goodrich Willard and that the term ‘sexual science’—which is usually attributed to Iwan Bloch as ‘Sexualwissenschaft’—was actually coined by the American phrenologist Orson Squire Fowler in 1852, the archives of American sexology have received scant attention in the period prior to Alfred Kinsey. In my article, I explore the role of Transcendentalism and phrenology in the production and development of American sexology and (...) sexual science. In particular, I argue that shifting the origins of sexology and sexual science away from Karl Heinrich Ulrichs and Karl-Maria Kertbeny and the more familiar narratives of the German invention of sexuality furnishes a radically different account of early sexology and sexual science. Rather than the unevenly homophilic sympathies of early German activists, their American counterparts promote marital, reproductive, loving sex and vilify prostitution, polygamy, masturbation, contraception, sex for pleasure, and, if they think to mention it, sodomy. In addition to this less progressive story, however, I argue that early American sexologists provide the first theories of gender and help to provide a fuller description of the politics of sexology and sexual science.

In lieu of an abstract, here is a brief excerpt of the content:A Hypothesis on the Origin of TradeThe Exchange of Lives for Sacrifice and SexPablo Díaz-Morlán (bio)introductionThe primary objective of this study is to propose a hypothesis regarding the origin of trade that will help to solve the enigma of why human groups, normally each other's enemies, stopped exchanging blows in order to exchange things. The complexity of this crucial step forward in the relationships between hostile primitive (...) groups can be summarized as follows. In order for an exchange to take place, both parties must take part in it voluntarily because they see a mutual benefit in doing so. In turn, both parties should be aware that in order to obtain what interests them, which is closely guarded by the other party, in return, they must hand over what the other party is interested in. The perception of the interest of the other plays a crucial role in trade, both today and in its origins. The next step to be taken after a successful initial exchange was its consolidation, after it had been proved that it mutually benefited groups who had, until then, been enemies. Once established, this pacific exchange would have diversified considerably and its complexity would have increased significantly. An added [End Page 165] advantage, which was unexpected but real, was that its subsequent usefulness in curbing violence contributed to its growing expansion. The emergence of a comparative advantage in the groups that adopted trade would have guaranteed their future progress with respect to those that continued to systematically adopt violent conduct toward their neighbors.1Throughout this study, we will come across the old idea that the market prevents war. Without a doubt, trade and war between individuals and groups are closely connected, but the boundaries between them are fuzzy and their demarcation has proven elusive to researchers. Albert Hirschman studied the intellectual climate in the seventeenth and eighteenth centuries in favor of trade and the express declaration of Montesquieu that "peace is the natural effect of trade."2 Since then, this idea has gained ground among researchers of economics and other fields of knowledge. In L'enfer des choses and subsequent works, Jean-Pierre Dupuy and Paul Dumouchel defend that the economy (the market) is a substitute for the sacred, containing violence through violent means. The market contains violence in the two senses of the term contain: It holds it and curbs it; it is both the poison and the remedy. The consumer society makes all objects available to everyone and in this way deactivates mimetic rivalry, deferring violent conflicts. But it is only a temporary remedy. In the words of Girard, "It is always necessary to find new toys."3Following the path initiated by Dumouchel and Dupuy, with their criticism of the free market economy and their proposal for a new notion of scarcity, in his text The Empire of Value, André Orléan claims that money is at the origin of the market. My analysis alludes to a moment prior to that established by Orléan. He maintains that he does not contemplate the historical origin of money but instead uses the expression "the conceptual origin of money." In fact, when he defends the essential monetary base of the market, he refers to an already developed market system, that is, an economic system for which the operation is structured around the institution of the market.4 Mark R. Anspach also criticized the market system in his book À Charge de Revanche. This author proposes the transcending of the perverse logic of vengeance that defines both war and the market that transforms it into a positive reciprocity based on the gift. This constitutes a type of shift away from looking at the past (settling old accounts) to looking toward the future, embracing gratitude, which gives rise to the initial gesture of giving.5 This study analyzes a time prior to that examined by Orléan and Anspach. It was the moment of hominization, that is, mimicry, the subsequent violence that threatened the survival of human groups and, as we will seek to explain, the market as an institution that has accompanied humankind since its conformation as a species...

In a compelling chronicle of her search to understand Beauvoir's philosophy in The Second Sex, Margaret A. Simons offers a unique perspective on Beauvoir's wide-ranging contribution to twentieth-century thought. She details the discovery of the origins of Beauvoir's existential philosophy in her handwritten diary from 1927; uncovers evidence of the sexist exclusion of Beauvoir from the philosophical canon; reveals evidence that the African-American writer Richard Wright provided Beauvoir with the theoretical model of oppression that she used in The Second Sex; (...) shows the influence of The Second Sex in transforming Sartre's philosophy and in laying the theoretical foundations of radical feminism; and addresses feminist issues of racism, motherhood, and lesbian identity. Simons also draws on her experience as a Women's Liberation organizer as she witnessed how women used The Second Sex in defining the foundations of radical feminism. Bringing together her work as both activist and scholar, Simons offers a highly original contribution to the renaissance of Beauvoir scholarship. (shrink)

Evolutionary changes in traits that affect both ecological divergence and mating signals could lead to reproductive isolation and the formation of new species. Insect cuticular hydrocarbons (CHCs) are potential examples of such dual traits. They form a waxy layer on the cuticle of the insect to maintain water balance and prevent desiccation, while also acting as signaling molecules in mate recognition and chemical communication. Because the synthesis of these hydrocarbons in insect oenocytes occurs through a common biochemical pathway, natural or (...) sexual selection on one role may affect the other. In this review, we explore how ecological divergence in insect CHCs can lead to divergence in mating signals and reproductive isolation. We suggest that the evolution of insect CHCs may be ripe models for understanding ecological speciation. (shrink)

This is a review of Margaret Simons's book, Beauvoir and the Second Sex: Feminism, Race, and the Origins of Existentialism.

In this article, we argue that there is an essential difference between social intelligence and creative intelligence, and that they have their foundation in human sexuality. For sex differences, we refer to the vast psychological, neurological, and cognitive science research where problem-solving, verbal skills, logical reasoning, and other topics are dealt with. Intelligence tests suggest that, on average, neither sex has more general intelligence than the other. Though people are equals in general intelligence, they are different in special forms of (...) intelligence such as social intelligence and creative intelligence, the former dominant in women, the latter dominant in men. The dominance of creative intelligence in men needs to be explained. The focus of our research is on the strictly anthropological aspects, and consequently our explanation for this fact is based on the male-female polarity in the mating systems. Sexual dimorphism does not only regard bodily differences but implies different forms of sex life. Sex researchers distinguish between two levels of sexual intercourse: procreative sex and recreational sex, and to these we would add “creative sex.” On all three levels, there is a behavioral difference between men and women, including the subjective experience. These differences are as well attributed to culture as genetically founded in nature. Sexual reproduction is only possible if females cooperate. Their biological inheritance makes females play a decisive role in mate choice. Recreational sex for the purpose of pleasure rather than reproduction results from female extended sexual activity. Creative sex, on the contrary, is a specifically male performance of sexuality. We identify creative sex with eroticism. Eroticism evolved through the transformation of the sexual drive into a mental state of expectation and fantasizing. Hence, sex differences (that nowadays are covered up by cultural egalitarianism) continue to be the evolutionary origin of the difference between social and creative intelligence. (shrink)

Frequent independent origins of environmental sex determination (ESD) are assumed within amniotes. However, the phylogenetic distribution of sex‐determining modes suggests that ESD is likely very ancient and may be homologous across ESD groups. Sex chromosomes are demonstrated to be old and stable in endothermic (mammals and birds) and many ectothermic (non‐avian reptiles) lineages, but they are mostly non‐homologous between individual amniote lineages. The phylogenetic pattern may be explained by ancestral ESD with multiple transitions to later evolutionary stable genotypic sex determination. (...) It is pointed out here that amniote ESD shares several key aspects with sequential hermaphroditism of fishes such as a lack of sex differences in genomes, biased population sex ratios, and potentially also molecular mechanism related to general stress responses. Here, it is speculated that ESD evolves via a heterochronic shift of the sensitive period of sex change from the adult to the embryonic stage in a hermaphroditic amniote ancestor.

Paper, $19.95.Anyone who is seriously interested in Simone de Beauvoir’s place in the history of philosophy must contend sooner or later with the fact that she denied, repeatedly and vehemently throughout her lifetime, that she was a philosopher. Of course, a certain species of Beauvoir-detractor will be tempted to take these denials at face value, especially since they almost always went hand in hand with Beauvoir’s plausible-sounding [End Page 688] declarations that anything philosophical about her work could be traced to the thinking of her lifelong companion Jean-Paul Sartre, who, she underscored, was the “real” philosopher in their relationship. But the very strength and frequency of her abjurations of the title of philosopher is a sign that, like Freud, Beauvoir (who wrote several straightforwardly philosophical essays, including the monograph-length Ethics of Ambiguity and Pyrrhus et Cınéas) was motivated not so much by modesty or self-abnegation but by a desire to distance herself from what counted, at least in the middle of this century, as philosophy.For most of the past 50 years, English-speaking readers of Beauvoir have simply accepted her portrayal of her relationship to philosophy. On the ordinary view, The Second Sex, while an important historical touchstone for “feminist theory” is not, or not quite, a philosophical piece of writing, and those of her publications that merit that title are mere apologetics for Sartrean existentialism. But in the years since Beauvoir’s death in 1986 allowed for the release of her voluminous and revealing letters to Sartre, more and more feminist philosophers have been taking a second look at The Second Sex and Beauvoir’s other essays and fiction as they try to engage productively both with non-academic feminist work and with the philosophical mainstream. As a result, the difficult question of just how to assess Beauvoir’s relationship both to philosophy in general and to Sartre in particular has become pressing and is at the center of the four books under review here.The authors of these books are each committed, in their own sometimes strikingly different ways, to two theses: first, that to understand Beauvoir’s place in the history of philosophy one must study her appropriations of the work of philosophers other than just Sartre and, second, that at the heart of Beauvoir’s enterprise in all of her work is a desire to think about how to create and sustain reciprocity between an existentially committed self and an equally autonomous other.The most historically oriented and, on my view, meticulous exploration of Beauvoir’s relationship to her philosophical influences is Lundgren-Gothlin’s superb Sex and Exıstence, which chronicles Beauvoir’s indebtedness to and interest in, especially, Hegel and Marx. Lundgren-Gothlin, a philosophically trained Swedish intellectual historian, shows decisively that one cannot make philosophical sense of The Second Sex as long as one reduces its philosophical dimension to boilerplate Sartreanism. Indeed, given Sartre’s antipathy toward Marx and his ambivalence about Hegel in Beıng and Nothingness, Lundgren-Gothlin’s work raises serious questions about the extent to which Beauvoir’s considered views in The Second Sex are even compatible with those of the early...

Vigil's socio-relational framework of sex differences in emotional expressiveness emphasizes general sex differences in emotional responding, but largely ignores the social context in which emotions are expressed. There is much empirical evidence showing that sex differences in emotion displays are flexible and a function of specific social roles and demands, rather than a reflection of evolutionary-based social adjustments.

A Sociology of Sex and Sexuality offers an historical sociological analysis of ideas about expressions of sexual desire, combining both primary and secondary historical and theoretical material with original research and popular imagery in the contemporary context. While some reference is made to the sexual ideology of Classical Antiquity and of early Christianity, the major focus of the book is on the development of ideas about sex and sexuality in the context of modernity. It questions the widespread assumption that the (...) anxieties and fears associated with old sexual mores have been overcome in the late twentieth century context, and asks whether the discourses of Queer sexual politics have successfully fractured the binary categories of heterosexuality and homosexuality. A Sociology of Sex and Sexuality will be of interest to students in the fields of sociology, sexual history, gender studies and cultural studies. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and Literature 25.2 (2001) 197-214 [Access article in PDF] The Origin of Stories:Horton Hears a Who Brian Boyd Works of art die without attention, and we should expect that any critical theory that cannot explain why we attend to art ought itself to be moribund. Yet the currently dominant approach to criticism, which I will dub Cultural Critique, 1 explains art in terms of the limited and (...) suspect perspectives of the culture (society, group, era) that produced it, or as the site of contestation or locus of imbrication of the ideological discourses of its time. Why anyone would want to attend to art, defined thus, becomes a mystery, unless audiences always do indeed crave ideological nourishment or indigestion. Surely we can do better.I would like to offer the outline of an alternative: an evolutionary explanation first for art, then for narrative, then for fiction. Then, since ontogeny recapitulates phylogeny, or at least sometimes helps us retrieve it, and since we have no printouts of Pleistocene potboilers, I will color in the outline by way of Dr. Seuss's children's classic, Horton Hears a Who, contrasting a sample evolutionary analysis of a single work of fiction with the kind of response typical of Cultural Critique.In art we do or make things simply in order to engage our attention, for the sake of attention, and we are not the only species to do so. Intelligence began to evolve because the world is full of potential information that can suggest advantageous courses of behavior. Curiosity evolved on top of intelligence--especially in the species that Konrad Lorenz liked to call "specialists in non-specialization," such as rats among rodents, corvids among songbirds, and humans among primates 2 --because it extends the range of information creatures can attend to and act on. As a result rats can prefer cognitive stimulation to food and sex. 3 As the most intelligent and versatile of species, we humans particularly like directing our attention to what repays our curiosity. [End Page 197]And like other particularly intelligent species, we like to do things that provide cognitive stimulation, whether they have any immediate survival value or not. Corvids (together with psittacines, the most intelligent of birds) enjoy a kind of aerial acrobatics that Lorenz unashamedly labels art. 4 Dolphins in a Hawaiian marine park have developed, without any human prompting, what has been called "air art," a kind of rhythmic gymnastics in which they deploy air bubbles from their blowholes like gymnasts' ribbons or hoops, or, to stress the affinity to art, a kind of aquatic analogue of light sculpture. 5 Chimpanzees appear to engage both in solitary imaginative play, like Kakama with the stick he famously and repeatedly handled as if it were a toy baby, 6 and in group activity, like rhythmic dances, 7 for the sheer pleasure they produce. In art as in so much else we had thought uniquely human, like tool-using or tool-making, like counting or culture, we are finding there are precursors elsewhere in nature. 8Because we are such a highly social species, we crave the attention of others. Human infants are distressed at adults who do not respond to them; 9 infants and children across cultures punish others by withdrawing attention. 10 At any age we like to command attention in ways we choose, for the ability to compete successfully for attention is closely correlated with status, 11 which raises rates of survival and reproduction. 12 And we can recognize something artistic in such forms of competitive animal attention-getting as the dances of lekking birds, the songs of songbirds or whales, or the extravagant architecture of bowerbirds. Not only do we like to command attention, we also enjoy simply sharing it with others, because this cements our place in a social group whose support we need. 13 Again, there are precursors in other species: the elaborate song of duetting songbirds, 14 or the communal dances of chimpanzees.Curiosity directed at what we can do that gives us cognitive pleasure, whether by engaging our own attention or...

This chapter examines the apparent proximity between Schopenhauer’s and Freud’s views on the nature and importance of what is called, amongst other things, ‘sexuality’, the ‘sexual impulse’, the ‘sexual instinct’ or ‘the ‘sexual drive’. It argues, against the idea that Freud's conception is basically borrowed from Schopenhauer, for the originality of Freud’s early theory of sexuality and suggest that the significance of this theory, apart from its obvious psychiatric and social import, lies in its possible contribution to a philosophical anthropology. (...) The chapter returns to the first, 1905 edition of the Three Essays on the Theory of Sexuality to argue for the originality of Freud’s conception of the sexual drive, in relation to both his philosophical and his psychiatric predecessors. It argues that Freud’s terminological shift in the Three Essays from the Geschlechtstrieb to the Sexualtrieb, both of which Strachey translates as ‘sexual instinct’ is evidence of a theoretical shift. Examining the notion of the Geschlechtstrieb in Freud’s predecessors and its relation to presumptions about the difference between the sexes allows the distinctiveness of Freud’s conception of the Sexualtrieb and thus his theory of sexuality to stand out. After examining the claims in the literature concerning the relation between Schopenhauer and Kant on the question of sexuality, it lays out the conception of the Geschlechtstrieb in Freud’s immediate psychiatric predecessors and its connection to the treatment of the same topic in Kant, Schopenhauer and Hartmann. It then demonstrates, with reference to Freud’s shift to the use of the term Sexualtrieb, how Freud develops a conception of the sexual drive and of sexuality that is quite different to the conception of the Geschlechtstrieb in Schopenhauer et al. The chapter ends by suggesting how Freud’s theory of sexuality is a contribution to a philosophical anthropology based on considerations quite foreign to his predecessors. (shrink)

A leading cognitive scientist argues that a deep sense of good and evil is bred in the bone. From John Locke to Sigmund Freud, philosophers and psychologists have long believed that we begin life as blank moral slates. Many of us take for granted that babies are born selfish and that it is the role of society—and especially parents—to transform them from little sociopaths into civilized beings. In Just Babies, Paul Bloom argues that humans are in fact hardwired with a (...) sense of morality. Drawing on groundbreaking research at Yale, Bloom demonstrates that, even before they can speak or walk, babies judge the goodness and badness of others’ actions; feel empathy and compassion; act to soothe those in distress; and have a rudimentary sense of justice. -/- Still, this innate morality is limited, sometimes tragically. We are naturally hostile to strangers, prone to parochialism and bigotry. Bringing together insights from psychology, behavioral economics, evolutionary biology, and philosophy, Bloom explores how we have come to surpass these limitations. Along the way, he examines the morality of chimpanzees, violent psychopaths, religious extremists, and Ivy League professors, and explores our often puzzling moral feelings about sex, politics, religion, and race. In his analysis of the morality of children and adults, Bloom rejects the fashionable view that our moral decisions are driven mainly by gut feelings and unconscious biases. Just as reason has driven our great scientific discoveries, he argues, it is reason and deliberation that makes possible our moral discoveries, such as the wrongness of slavery. Ultimately, it is through our imagination, our compassion, and our uniquely human capacity for rational thought that we can transcend the primitive sense of morality we were born with, becoming more than just babies. -/- Paul Bloom has a gift for bringing abstract ideas to life, moving seamlessly from Darwin, Herodotus, and Adam Smith to The Princess Bride, Hannibal Lecter, and Louis C.K. Vivid, witty, and intellectually probing, Just Babies offers a radical new perspective on our moral lives. (shrink)

Stories consist largely of representations of the human social environment. These representations can be used to influence the behavior of others (consider, e.g., rumor, propaganda, public relations, advertising). Storytelling can thus be seen as a transaction in which the benefit to the listener is information about his or her environment, and the benefit to the storyteller is the elicitation of behavior from the listener that serves the former’s interests. However, because no two individuals have exactly the same fitness interests, we (...) would expect different storytellers to have different narrative perspectives and priorities due to differences in sex, age, health, social status, marital status, number of offspring, and so on. Tellingly, the folklore record indicates that different storytellers within the same cultural group tell the same story differently. Furthermore, the historical and ethnographic records provide numerous examples of storytelling deliberately used as a means of political manipulation. This evidence suggests that storyteller bias is rooted in differences in individual fitness interests, and that storytelling may have originated as a means of promoting these interests. (shrink)

To examine the psychological origins of sex-typed news preferences, an online newsmagazine was presented to 246 German participants in a quasi-experimental design. The presented articles featured equal portions of social/interpersonal and achievement/performance topics. Newsreaders' selective news exposure was unobtrusively logged. Results show that, even when various intervening factors are eliminated, women read more about social/interpersonal topics than men did, and men spent more time on achievement/performance-related news than women. Newsreaders' self-esteem and gender role orientation influenced the preference of news content. (...) This contribution will also discuss the effects of sex-typed news exposure. (shrink)

This essay examines the proposal that psychological essentialism results from a history of natural selection acting on human representation and inference systems. It has been argued that the features that distinguish essentialist representational systems are especially well suited for representing natural kinds. If the evolved function of essentialism is to exploit the rich inductive potential of such kinds, then it must be subserved by cognitive mechanisms that carry out at least three distinct functions: identifying these kinds in the environment, constructing (...) essentialized representations of them, and constraining inductive inferences about kinds. Moreover, there are different kinds of kinds, ranging from nonliving substances to biological taxa to within-species kinds such as sex, and the causal processes that render these categories coherent for the purposes of inductive generalization vary. If the evolved function of essentialism is to support inductive generalization under ignorance of true causes, and if kinds of kinds vary in the implicit assumptions that support valid inductive inferences about them, then we expect different, functionally incompatible modes of essentialist thinking for different kinds. In particular, there should be differences in how biological and nonbiological substances, biological taxa, and biological and social role kinds are essentialized. The functional differences between these kinds of essentialism are discussed. (shrink)

Sex differences in aggressive and risk-taking behaviors have practical implications for sexual integration of military combat units. The social-role theory implies that female soldiers will adapt to their role and display the same aggressive and risk-taking propensities as their male comrades. If sex differences reflect evolved propensities, however, adoption of the soldier's role is unlikely to eliminate those differences.

This is only the most recent incarnation of the fear of fat (...) Black women, which Sabrina Strings shows took root more than two hundred years ago. Strings weaves together an eye-opening historical narrative ranging from the Renaissance to the current moment, analyzing important works of art, newspaper and magazine articles, and scientific literature and medical journals—where fat bodies were once praised—showing that fat phobia, as it relates to Black women, did not originate with medical findings, but with the Enlightenment era belief that fatness was evidence of “savagery” and racial inferiority. The author argues that the contemporary ideal of slenderness is, at its very core, racialized and racist. Indeed, it was not until the early twentieth century, when racialized attitudes against fatness were already entrenched in the culture, that the medical establishment began its crusade against obesity. An important and original work, Fearing the Black Body argues convincingly that fat phobia isn’t about health at all, but rather a means of using the body to validate race, class, and gender prejudice.

Sex, Gender, Ethics, and the Darwinian Evolution of Humanity examines the impact of Darwin's 'Descent of Man' on contemporary biology and the humanities. Its publication in 1871 was a founding event in anthropology. Its content was primarily concerned with the development of sexual life, social life, and intellectual life, not only as outcomes of evolution, but as components that have actively intermixed over time with the evolutionary mechanism of natural selection. The stamp of Darwinism on modern thought is still very (...) important and brings novelties to academic studies. Several fields influenced by Darwinian anthropology developed in recent decades, including evolutionary ethics, the evolution of sociality and sexual communication in animal and plant species. Sociobiology and evolutionary psychology are topics that draw heavily on Darwin's 'Descent of Man'. The understanding of Darwin's thought has also progressed greatly in recent decades, following the systematic study of Darwin's correspondence and notebooks, leading to a reassessment of the development of his thought on humans, social groups, and heredity, and how they come together in his theory of evolution. The book combines a historical perspective on Darwin's achievement and his legacy. It will be of interest to students and scholars in a variety of fields, from experimental biology to the social and historical sciences. (shrink)

This paper examines the problematisation of sex-selective abortion (SSA) in UK parliamentary debates on Fiona Bruce's Abortion (Sex-Selection) Bill 2014–15 and on the subsequent proposed amendment to the Serious Crime Bill 2014–15. On the basis of close textual analysis, we argue that a discursive framing of SSA as a form of cultural oppression of minority women in need of protection underpinned Bruce's Bill; in contrast, by highlighting issues more commonly articulated in defence of women's reproductive rights, the second set of (...) debates displaced this framing in favour of a broader understanding, drawing on postcolonial feminist critiques, of how socio-economic factors constrain all women in this regard. We argue that the problematisation of SSA explains the original cross-party support for, and subsequent defeat of, the policies proposed to restrict SSA. Our analysis also highlights the central role of ideology in the policy process, thus making politics visible in policymaking. (shrink)

Preview: /Commentary: Richard Shusterman, Ars Erotica: Sex and Somaesthetics in the Classical Arts of Love, 436 pages./ Richard Shusterman’s work is remarkable, among other things, for extending the range and power of the discipline of aesthetics, conceived by him as fundamental to many dimensions of human experience. Indeed, he has driven aesthetics into entirely new ranges of phenomena and strategies for research, and also perhaps returned to an ancient sense of the centrality of aesthetic concepts such as beauty to virtually (...) every human endeavor. In many ways, I think, Shusterman is fulfilling John Dewey’s vision as expressed in Art as Experience, as well as spelling out in detail the implications of his own early book Pragmatist Aesthetics, exploring the aesthetic dimensions of all sorts of human activities. Schusterman’s somaesthetics, however, takes what we might call the aesthetics, or ordinary experience, and centers it on the body in a way that Dewey could not have foreseen. The book might have been titled The Aesthetics of Sex, and as soon as he broaches the topic it strikes one that this subject has been remarkably neglected within philosophical aesthetics, or even in Western philosophy as a whole. Considered as dimensions or arenas of human experience, the aesthetic and the erotic, as Shusterman shows in replete multi-cultural detail, are bound up entirely and from the origins in many or even all cultures.

BackgroundImportant sex and gender differences have been found in research on diabetes complications and treatment. Reporting on whether and how sex and gender impact research findings is crucial for developing tailored diabetes care strategies. To analyze the extent to which this information is available in current diabetes research, we examined original investigations on diabetes for the integration of sex and gender in study reporting.MethodsWe examined original investigations on diabetes published between January 1 and December 31, 2015, in the top five (...) general medicine journals and top five diabetes-specific journals (by 2015 impact factor). Data were extracted on sex and gender integration across seven article sections: title, abstract, introduction, methods, results, discussion, and limitations.ResultsWe identified 155 original investigations on diabetes, including 115 randomized controlled trials (RCTs) and 40 observational studies. Sex and gender were rarely incorporated in article titles, abstracts and introductions. Most methods sections did not describe plans for sex/gender analyses; 47 (30.3%) articles described plans to control for sex/gender in the analysis and 12 (7.7%) described plans to stratify results by sex/gender. While most articles (151, 97.4%) reported the sex/gender of study participants, only 10 (6.5%) of all articles reported all study outcomes separately by sex/gender. Discussion of sex-related issues was incorporated into 21 (13.5%) original investigations; however, just 1 (0.6%) discussed gender-related issues. Comparison by journal type (general medicine vs. diabetes specific) yielded only minor differences from the overall integration results. In contrast, RCTs performed more poorly on multiple sex/gender assessment metrics compared to observational studies.ConclusionsSex and gender are poorly integrated in current diabetes original investigations, suggesting that substantial improvements in sex and gender data reporting are needed to inform the evidence to support sex- and gender-specific diabetes care.

Opioid use disorder rarely presents as a unitary psychiatric condition, and the comorbid symptoms likely depend upon the diverse risk factors and mechanisms by which OUD can arise. These factors are heterogeneous and include genetic predisposition, exposure to prescription opioids, and environmental risks. Crucially, one key environmental risk factor for OUD is early life adversity. OUD and other substance use disorders are widely considered to derive in part from abnormal reward circuit function, which is likely also implicated in comorbid mental (...) illnesses such as depression, bipolar disorder, and schizophrenia. ELA may disrupt reward circuit development and function in a manner predisposing to these disorders. Here, we describe new findings addressing the effects of ELA on reward circuitry that lead to OUD and comorbid disorders, potentially via shared neural mechanisms. We discuss some of these OUD-related problems in both humans and animals. We also highlight the increasingly apparent, crucial contribution of biological sex in mediating the range of ELA-induced disruptions of reward circuitry which may confer risk for the development of OUD and comorbid neuropsychiatric disorders.

The COVID-19 pandemic has caused a global societal, economic, and social upheaval unseen in living memory. There have been substantial cross-national differences in the kinds of policies implemented by political decision-makers to prevent the spread of the virus, to test the population, and to manage infected patients. Among other factors, these policies vary with politicians’ sex: early findings indicate that, on average, female leaders seem more focused on minimizing direct human suffering caused by the SARS-CoV-2 virus, while male leaders implement (...) riskier short-term decisions, possibly aiming to minimize economic disruptions. These sex differences are consistent with broader findings in psychology, reflecting women’s stronger empathy, higher pathogen disgust, health concern, care-taking orientation, and dislike for the suffering of other people—as well as men’s higher risk-taking, Machiavellianism, psychopathy, narcissism, and focus on financial indicators of success and status. This review article contextualizes sex differences in pandemic leadership in an evolutionary framework. Evolution by natural selection is the only known process in nature that organizes organisms into higher degrees of functional order, or counteracts the unavoidable disorder that would otherwise ensue, and is therefore essential for explaining the origins of human sex differences. Differential sexual selection and parental investment between males and females, together with the sexual differentiation of the mammalian brain, drive sex differences in cognition and behavioral dispositions, underlying men’s and women’s leadership styles and decision-making during a global pandemic. According to thesexually dimorphic leadership specialization hypothesis, general psychobehavioral sex differences have been exapted during human evolution to create sexually dimorphic leadership styles. They may be facultatively co-opted by societies and/or followers when facing different kinds of ecological and/or sociopolitical threats, such as disease outbreaks or intergroup aggression. Early evidence indicates that against the invisible viral foe that can bring nations to their knees, the strategic circumspection of empathic feminine health “worriers” may bring more effective and humanitarian outcomes than the devil-may-care incaution of masculine risk-taking “warriors”.
