Notable in cross-cultural comparisons is the variable span of time between when children become economically self-sufficient and when they initiate their own reproductive careers. That variation is of interest because it shapes the age range of children reliant on others for support and the age range of children available to help out, which in turn affects the competing demands on parents to support multiple dependents of different ages. The age at positive net production is used as a proxy to estimate (...) the close of juvenile economic dependence among a group of Maya subsistence agriculturalists. Maya children produce more than they consume by their early to mid teens but remain in their natal households for a number of years before leaving home and beginning families of their own. The Maya results contrast markedly with those from several groups of hunter-gatherers and horticulturalists for whom we have similar data. Even in the Maya case, where children are self-sufficient at a relatively young age, parents are unable to support their children without help from others. The production surplus of older children appears to help underwrite the cost of large Maya families and subsidize their parents’ continued reproduction. (shrink)

Research in nonindustrial small-scale societies challenges the common perception that human childhood is universally characterized by a long period of intensive adult investment and dedicated instruction. Using return rate and time allocation data for the Savanna Pumé, a group of South American hunter-gatherers, age patterns in how children learn to become productive foragers and from whom they learn are observed across the transition from childhood to adolescence. Results show that Savanna Pumé children care for their siblings, are important economic contributors, (...) learn by doing rather than by instruction, and spend their time principally in the company of other children. This developmental experience contrasts with that of children in postindustrial societies, who are dependent on adults, often well past maturity; learn in formal settings; and spend much of their time in the company of adults. These differences raise questions about whether normative behaviors observed in postindustrial societies are representative of human children. This comparison also identifies the potential mismatch between hunter-gatherer and postindustrial societies in the extent to which children may be well adapted to learn from and teach each other. In particular, spending time in autonomous work and play groups develops the cooperation and coordination skills that are foundational to human subsistence and growing up to be socially and productively adept adults and parents.

The evolution of cooperative breeding is complex, and particularly so in humans because many other life history traits likely evolved at the same time. While cooperative childrearing is often presumed ancient, the transition from maternal self-reliance to dependence on allocare leaves no known empirical record. In this paper, an exploratory model is developed that incorporates probable evolutionary changes in birth intervals, juvenile dependence, and dispersal age to predict under what life history conditions mothers are unable to raise children without adult (...) cooperation. The model’s outcome variable (net balance) integrates dependent children’s production and consumption as a function of varying life history parameters to estimate the investment mothers or others have to spend subsidizing children. Results suggest that maternal-juvenile cooperation can support the early transition toward a reduction in birth intervals, a longer period of juvenile dependence, and having overlapping young. The need for adult cooperation is most evident when birth intervals are short and age at net production is late. Findings suggest that the needs of juveniles would not have been an early selective force for adult cooperation. Rather, an age-graded division of labor and the mutual benefits of maternal-juvenile cooperation could be an important, but overlooked step in the evolution of cooperative breeding. (shrink)

Attention has been given to cross-cultural differences in adolescent growth, but far less is known about developmental variability during juvenility (ages 3–10). Previous research among the Pumé, a group of South American foragers, found that girls achieve a greater proportion of their adult stature during juvenility compared with normative growth expectations. To explain rapid juvenile growth, in this paper we consider girls’ activity levels and energy expended in subsistence effort. Results show that Pumé girls spend far less time in subsistence (...) tasks in proportion to their body size compared with adults, and they have lower physical activity levels compared with many juveniles cross-culturally. Low activity levels help to explain where the extra energy comes from to support rapid growth in a challenging environment. We suggest that activity levels are important to account for the variation of resource and labor transfers in mediating energy availability. (shrink)

Dispersal of individuals from their natal communities at sexual maturity is an important determinant of kin association. In this paper we compare postmarital residence patterns among Pumé foragers of Venezuela to investigate the prevalence of sex-biased vs. bilateral residence. This study complements cross-cultural overviews by examining postmarital kin association in relation to individual, longitudinal data on residence within a forager society. Based on cultural norms, the Pumé have been characterized as matrilocal. Analysis of Pumé marriages over a 25-year period finds (...) a predominant pattern of natalocal residence. We emphasize that natalocality, bilocality, and multilocality accomplish similar ends in maximizing bilateral kin affiliations in contrast to sex-biased residential patterns. Bilateral kin association may be especially important in foraging economies where subsistence activities change throughout the year and large kin networks permit greater potential flexibility in residential mobility.

In the mid 1970s labor-saving technology was introduced into a Maya subsistence agricultural community that markedly increased the efficiency with which maize could be ground and water collected. This increased efficiency introduces a possible savings in the time that women allocate to work, which can be reapportioned to child care, food production, domestic work, or leisure. An earlier study suggested that this labor-saving technology had a positive effect in decreasing the age at which these Maya women begin their reproductive careers. (...) Although there is a statistical association between the age at which women bear their first child and the introduction of modern technology, this association does not demonstrate that the decline in age at first birth is causally related to the presence of technology. This paper pursues two objectives to evaluate this potential causal relationship in greater detail. First, a theory relating technological change to the initiation of a reproductive career is briefly developed in order to make qualitative predictions about behavioral changes as a response to changing technology. Second, these predictions are then tested against time allocation data recently collected in this same Maya community.We suggest that both of the conditions necessary to initiate reproduction—fecundity and access to mates—fundamentally depend on the amount of help that a girl provides to her family. Further, the help that a girl provides can be affected by technological changes. Analyses show that when modern technology is available, unmarried young women do not change the time allocated to domestic tasks and child care, and allocate more time to low-energy leisure activities. This lack of perceived benefit to working more and a potential concomitant shift towards a positive energy balance may in part explain why Maya women leave home and initiate reproduction at a younger age after labor-saving technology is introduced.

The question of why helpers help is debated in the cooperative breeding literature. Recent reevaluations of inclusive fitness theory have important implications for traditional populations in which the provisioning of young occurs in the context of intergenerational transfers. These transfers link older and younger generations in an economic relationship that both minimizes the demand for help and the cost of helping.

In lieu of an abstract, here is a brief excerpt of the content:Reifying Relevance in Mild Cognitive Impairment:An Appeal for Care and CautionJanice E. Graham (bio) and Karen Ritchie (bio)KeywordsAlzheimer’s disease, construction, dementia, market forces, mild cognitive impairmentWe thank the reviewers for their thoughtful comments that probe shadowy areas in our argument, and we welcome this opportunity to elucidate our position. First, we are not repudiating the natural and social facts of pathologic brain degeneration and the physical and cognitive (...) impairments that manifest in people affected by dementia disorders. We are, however, questioning the epistemology, politics, and persistence by some to harden the construct of mild cognitive impairment (MCI) prematurely as a "natural" precursor to dementia. We suggested insufficiencies in viewing MCI as prodromal to Alzheimer's disease (AD; Graham and Ritchie 2006, 36), and pointed to evidence for the prognostic irrelevance of some MCI subcategories (35). The commentators have read our manuscript as suggesting that AD and MCI are different kinds, and that a diagnosis of AD is more "real" than that of MCI. But AD is also fraught with classification issues, as we describe in the section of our paper that deals with consensus committees, published practice guidelines, and the determination of treatment efficacy. Like MCI, AD is a heterogeneous condition, but unlike MCI, AD is a constructed practical kind that does some "work" beyond essentialist (neural degeneration, brain atrophy) claims. Its criteria identify people with well-defined dementia symptoms and multiple cognitive and functional impairments who are in need of, and benefit from, support. Even with these criteria, however, there have been great attempts to achieve definitional accuracy in dementia diagnoses. Practical refinements to the differential diagnosis of dementia based on solid research evidence have made way for more specific recognitions of vascular dementias, dementia of the Lewy body type, and other subtypes beyond AD. So AD too has been subject to more careful, more cautious operationalization in recent years, with research supporting multiple factors and the comorbidity of several types (kinds) of dementia in any one individual.Our paper takes up concerns that are not resolved for dementia and suggests that the nascent category of MCI is still so insufficiently defined as to be ambiguous, and as such, is in danger of identifying individuals with what will be, and has [End Page 57] already been, linked to a debilitating and deeply stigmatizing and fatal disorder (AD). We are not contesting the reality that some people begin to display early signs of cognitive loss, nor are we suggesting that symptoms be ignored; as researchers, we stand behind the careful tracking of symptoms and signs in patients and research participants as an essential clinical and research practice. In a era where the public has been made wary of the potentially fatal effects of new treatments whose more careful scrutiny in specific populations would have saved lives (e.g., Fontanarosa, Rennie, and DeAngelis 2004; Psaty and Furberg 2005), and made all the more popular by what Kramer coined "diagnostic bracket creep" (1993, 15), we are questioning the drivers and value of a premature diagnostic classification whose definitional accuracy is neither sufficient nor effective for specific identification of individuals.That matters of fact are constructed does not take away from their natural fact. Some people have subjective reports or show objective evidence of cognitive decline while having preserved activities of daily living—the construction of this evidence indicates they are not normal and they are not demented. Based on such evidence, where then does the balance of probability for MCI lie? A multidisciplinary international group of experts gathered in Stockholm in 2003 to discuss MCI concepts (Winblad et al. 2004). They acknowledged that the heterogeneous etiology of MCI contributes to "some confusion concerning the specific boundaries of the condition", stating that this "not normal, not demented" condition is nonetheless "useful both clinically and as a research entity" (p. 241). Importantly, they concluded that MCI needs "better definition" (p. 246). It was at this stage that we first wrote our manuscript, and in the subsequent two years we have eagerly awaited new studies, and the recognition of flexible, practical subtypes to evolve.We state "that MCI cannot be considered to be a separate clinical entity" (Graham and...

In the multi-faceted trajectory of post-Kantian thought, Schelling—both the person and his philosophy—has always been a controversial figure. Popular historical accounts focus on his precocious interventions as part of the ‘Jena set’, initially building on Fichte's philosophy of the ‘I’, but quickly coming to challenge his predecessor's philosophical dominance. In the crucial period of the late 1790s, Schelling's most notable intervention was to develop a philosophy of nature alongside the Kantian and Fichtean theories of transcendental subjectivity, which caught the attention (...) of Goethe and led to his appointment, at the age of twenty-three, as professor of philosophy at the University of Jena. But Schelling's life and philosophical work continued well beyond this well-documented period, culminating in a late system in which he developed key ideas surrounding freedom, existence, modality and the history of human consciousness that all revolved around a distinction between what he called negative and positive philosophy. This distinction, and his insistence on the need for the development of the latter mode of philosophy, came to challenge some of the core assumptions of the largely rationalist German idealist project and it remains, to this day, perhaps the most powerful alternative to the Hegelian system that rose to dominance already within Schelling's own lifetime, but also well beyond it.

In this paper I describe and defend an account of virtuous motivation that differs from what we might call ordinary moral motivation. It is possible to be morally motivated without being virtuously motivated. In the first half of the essay, I explore different senses of moral motivation and the philosophical puzzles and problems it poses. In the second half, I give an account of virtuous motivation that, unlike ordinary moral motivation, requires the motivational structure characteristic of a fully virtuous person. (...) I draw on Aristotle's account of virtuous action to argue that a fully virtuous agent's judgment reflects a robust form of moral knowledge about what features of an action render it virtuous and hence, choiceworthy. Virtuously motivated actions are chosen in light of those features and are accompanied by the affective state appropriate to the overall moral landscape in which the judgment is made. (shrink)

Paradigmatic as Beauvoir’s thinking is for contemporary Western feminism, in the light of global developments, it is important to note that her feminist ideals surpass the dominant forms of Western liberalism in substantial ways. Her positive concept of ‘ethical’ freedom does not correspond to Western liberalism’s negative concept of freedom as the absence of constraints. Nor does her gender egalitarian concept of society resemble Western liberalism’s model of society with its dichotomous organization of labor and care. It is argued that (...) Western feminism, as it was conceived by Beauvoir, can be elaborated substantially, as well as strategically, into an inclusive feminism for a globalizing, yet culturally plural world. (shrink)

-/- Carefully considering the difference in the philosophical potential of page poetry and performance poetry, Karen Simecek argues that it is only by considering them side by side that the unique cognitive value of each can be realised. -/- Focusing on spoken word poetry reveals the importance of voice and embodied words to the differing epistemic rewards of engaging with contemporary works of poetry in both private reading and live performance. This concept of embodied voice progresses a new line (...) of thinking in the cognitivism debate and unlocks the philosophical value of engaging with poetry. Simecek's discussion of performed poetry also advances discussions of affect and experience in contemporary analytic aesthetics which raise new insights and connections within the field. -/- The moral significance of the differing effects of poetry finds comprehensive articulation through a rich philosophical analysis of the thoughts and affects which arise in particular contexts. Simecek concludes that when page poetry is treated as paradigmatic, this enables reflection in the singular, whereas taking poetry in live performance as paradigmatic enables reflection on what is shared and shareable with others.

This paper defends an interpretation of Fanon's theory of recognition as revolving around his claim that we have a basic right to demand human behaviour from the other. Developing key Hegelian ideas in a novel direction, I argue that Fanon's theory of recognition employs a concretely universal concept of humanity as a normative orientation for establishing what he calls a ‘world of reciprocal recognitions’, which he equates with the creation of a ‘human reality’. In the first section, I take up (...) the three passages from Hegel's Phenomenology of Spirit cited by Fanon in Black Skin, White Masks to outline three key features of Fanon's theory of recognition. In section two, I argue that there are three senses of ‘universal humanity’ operative in Fanon's work: a false universal, an abstract universal, and a concrete universal. Whereas the first two are critical, pejorative uses, the third provides the normative orientation for his account of recognition and social struggle. In the third section, I show how Fanon combines features of Hegel's concrete universal with features of Sartre's existential humanism in order to avoid an essentialist or ahistorical approach to human nature. Specifically, I argue that the ideas of self-transcendence and a universal human condition shed light on what Fanon refers to as the right of reciprocal recognition to demand human behaviour from the other, and our one human duty to not renounce our freedom.

It is widely acknowledged that the gradual emergence of the modern nation-state is associated with intensified interest in the government of childhood. Grounded in the Foucauldian literature on governmentality and drawing on a broad range of disciplines, this book examines the government of childhood in the West from the early modern period to the present. The book deals with three key time periods, examining shifts in the conceptualization and regulation of childhood and child-rearing between the late sixteenth and late eighteenth (...) century; between the late eighteenth century and the mid/late twentieth century and the period from the late twentieth century to the present day. Building on the work of Chris Jenks, The Government of Childhood deploys the images of the Dionysian and Apollonian images of childhood as symbolic targets of power/knowledge and presents a third model - the Athenian child - as a symbolic target of modes of exercising power over the young that is grounded in children's capacity for agency.

Although for a long time, Dutch academic philosophy was characterized by a pluralism of – imported – philosophical frameworks and paradigms, in more recent decades, a type of ‘normal philosophy’, in the Kuhnian sense, has become dominant which aims to solve ethical and political problems and dilemmas through rational-normative argumentation. Contrary to what is often claimed, the new 'normal philosophy' amounts not to thinking ‘beyond the analytic-continental divide’ in a fruitful synthesis, but to the subsumption of continental philosophical themes and (...) concepts under the analytic tradition. The potentially critical tenor of continental philosophy threatens to be ‘solved’ by this subsumption. ‘Normal philosophy’, with its emphasis on rational-normative argumentation, risks leading to a state philosophy that fits in with existing policy questions, ignoring systemic and structural power inequalities. I argue that the journal Krisis, in keeping with its original principles, should hang on to critical philosophical reflection, which today is needed more than ever, specifically – pace current right-wing and left-wing populist attacks on identity politics – on systemic, multiple forms of deprivation and oppression.

A theoretical physicist and feminist theorist, Karen Barad elaborates her theory of agential realism, a schema that is at once a new epistemology, ontology, and ethics.

We frequently speak of certain things or phenomena being built out of or based in others. Making Things Up concerns these relations, which connect more fundamental things to less fundamental things: Karen Bennett calls these 'building relations'. She aims to illuminate what it means to say that one thing is more fundamental than another.

Performance is increasingly important to the poet, which is evidenced by the growing numbers of videos and audio recordings online including YouTube, the National Poetry library, and Poetry Archive. As a result, there are greater opportunities to engage with poets reading their own work and consequently, there is a need to move away from thinking of poetry as primary something that takes shape on the page. Furthermore, by refocusing attention to poetry as an oral artform, in particular to poetry performance, (...) different ways of understanding the value of poetry come to the fore. The live poetry performance, I argue, offers an attempt to reclaim the personal individual expression of language in contemporary society and demands attention by the audience because of the role of voice and body in the performance. Through awareness of ‘uniqueness of voice,’ the performed poem becomes a site of collective meaning making with individual identity intact as a shared endeavour between performer and audience, and necessarily resists appropriation (in the sense that the words experienced cannot be divorced from the performer or the performance space to serve as a proxy for meaning elsewhere). This chapter therefore makes an argument for the need to engage with spoken word and performance poetry in the live performance space. (shrink)

We hypothesised that belief in conspiracy theories would be predicted by the general tendency to attribute agency and intentionality where it is unlikely to exist. We further hypothesised that this tendency would explain the relationship between education level and belief in conspiracy theories, where lower levels of education have been found to be associated with higher conspiracy belief. In Study 1 participants were more likely to agree with a range of conspiracy theories if they also tended to attribute intentionality and (...) agency to inanimate objects. As predicted, this relationship accounted for the link between education level and belief in conspiracy theories. We replicated this finding in Study 2, whilst taking into account beliefs in paranormal phenomena. These results suggest that education may undermine the reasoning processes and assumptions that are reflected in conspiracy belief. (shrink)

Recently much has been made of the grounding relation, and of the idea that it is intimately tied to fundamentality. If A grounds B, then A is more fundamental than B (though not vice versa ), and A is ungrounded if and only if it is fundamental full stop—absolutely fundamental. But here is a puzzle: is grounding itself absolutely fundamental?

Recent defenses of shaming as an effective tool for identifying bad practice and provoking social change appear compatible with feminism. I complicate this picture by examining two instances of online feminist shaming that resulted in shame backlashes. Shaming requires the assertion of social and epistemic authority on behalf of a larger community, and is dependent upon an audience that will be receptive to the shaming testimony. In cases where marginally situated knowers attempt to “shame up,” it presents challenges for feminist (...) uses. (shrink)

A variety of relations widely invoked by philosophers—composition, constitution, realization, micro-basing, emergence, and many others—are species of what I call ‘building relations’. I argue that they are conceptually intertwined, articulate what it takes for a relation to count as a building relation, and argue that—contra appearances—it is an open possibility that these relations are all determinates of a common determinable, or even that there is really only one building relation.

In the 1960’s Brian Goodwin published a couple of mathematical models showing how feedback inhibition can lead to oscillations and discussed possible implications of this behaviour for the physiology of the cell. He also presented key ideas about the rich dynamics that may result from the coupling between such biochemical oscillators. Goodwin’s work motivated a series of theoretical investigations aiming at identifying minimal mechanisms to generate limit cycle oscillations and deciphering design principles of biological oscillators. The three-variable Goodwin model (adapted (...) by Griffith) can be seen as a core model for a large class of biological systems, ranging from ultradian to circadian clocks. We summarize here main ideas and results brought by Goodwin and review a couple of modeling works directly or indirectly inspired by Goodwin’s findings. (shrink)

The paper is an extended discussion of what I call the ‘dismissive attitude’ towards metaphysical questions. It has three parts. In the first part, I distinguish three quite different versions of dismissivism. I also argue that there is little reason to think that any of these positions is correct about the discipline of metaphysics as a whole; it is entirely possible that some metaphysical disputes should be dismissed and others should not be. Doing metametaphysics properly requires doing metaphysics first. I (...) then put two particular disputes on the table to be examined in the rest of the paper: the dispute over whether composite objects exist, and the dispute about whether distinct objects can be colocated. In the second part of the paper, I argue against the claim that these disputes are purely verbal disputes. In the third part of the paper, I present a new version of dismissivism, and argue that it is probably the correct view about the two disputes in question. They are not verbal disputes, and the discussion about them to date has not remotely been a waste of time. At this stage, however, our evidence has run out. I argue that neither side of either dispute is simpler than the other, and that the same objections in fact arise against both sides. (For example, the compositional nihilist does not in fact escape the problem of the many, and the one-thinger does not in fact escape the grounding problem.). (shrink)

Ethical care is beginning to be recognised as care that accounts for the views of those at the receiving end of care. However, in the context of palliative and supportive district nursing care, the patients’ and their carers’ views are seldom heard. This qualitative research study explores these views. Data were collected through semi-structured interviews with 26 patients with palliative and supportive care needs receiving district nursing care, and 13 of their carers. Participants were recruited via community nurses and hospices (...) between September 2010 and October 2011. Post-structural discourse analysis is used to examine how discourses operate on a moral level. One discourse, ‘busyness’, is argued to preclude a moral form of nursing care. The discourse of friendship is presented to contrast this. Discussion explores Gallagher’s ‘slow ethics’ and challenges the currently accepted ways of measuring to improve quality of care concluding that quality cannot be measured. (shrink)

This book discusses the notion that quantum gravity may represent the "breakdown" of spacetime at extremely high energy scales. If spacetime does not exist at the fundamental level, then it has to be considered "emergent", in other words an effective structure, valid at low energy scales.

A lot of people believe that distinct objects can occupy precisely the same place for the entire time during which they exist. Such people have to provide an answer to the 'grounding problem' – they have to explain how such things, alike in so many ways, nonetheless manage to fall under different sortals, or have different modal properties. I argue in detail that they cannot say that there is anything in virtue of which spatio-temporally coincident things have those properties. However, (...) I also argue that this may not be as bad as it looks, and that there is a way to make sense of the claim that such properties are primitive. (shrink)
