AbstractZero-sum thinking and aversion to trade pervade our society, yet fly in the face of everyday experience and the consensus of economists. Boyer & Petersen's (B&P's) evolutionary model invokes coalitional psychology to explain these puzzling intuitions. I raise several empirical challenges to this explanation, proposing two alternative mechanisms – intuitive mercantilism (assigning value to money rather than goods) and errors in perspective-taking.

Louis Althusser was the most influential philosopher to emerge in the revival of Marxist theory occasioned by the radical movements of the 1960s. His influence is, on the face of it, surprising, since Althusser’s Marx is not the theorist of revolutionary self-emancipation celebrated by the early Lukács. According to Althusser, Marx, along with Freud, was responsible for a ‘decentring’ of the human subject. History is ‘a process without a subject’. Its movement is beyond the comprehension of individual or collective subjects, and can only be grasped by a scientific ‘theoretical practice’ which keeps its distance from everyday experience. This austere version of Marxism nevertheless captured the imagination of many young intellectuals by calling for a ‘return to Marx’, with the implication that his writings had been distorted by the official communist movement. In fact, Althusser later conceded, his was an ‘imaginary Marxism’, a reconstruction of historical materialism reflecting the same philosophical climate that produced the post-structuralist appropriations of Nietzsche and Heidegger by Deleuze, Derrida and Foucault. Most of the philosophical difficulties in which Althusser found himself can be traced back to the impossibility of fusing Marx’s and Nietzsche’s thought into a new synthesis.

This article explores the transnational contest over sacred authority in contemporary Shi’i Islam as it plays out between contemporary maraji’ (sources of emulation) and the Iranian Supreme Leader, and in practice between their respective networks. It engages with existing assessments of the marja’iyya as an institution in crisis and argues instead that the marja’iyya has structural capacities that help maintain its potential in the face of the power exerted by the Supreme Leader. This in turns shapes the nature and outcome of the contest, including the need for the latter to accommodate with competing religious authorities. In the first part, the article offers a conceptualisation of the marja’iyya’s potential on the basis of three of its intrinsic features: its polycephalic nature and the broad temporal and geographical scope of a marja’’s authority. The second part offers a case study of the transnational contest over sacred authority in a specific locale. It maps the various (institutionalised) networks associated with Middle Eastern authorities, the Supreme Leader included, in London. Networks are however not hard-bound entities, as illustrated by the cross-networks navigation of their members. Furthermore, networks operate not only in competition but also in collaboration with each other. The contemporary contest over Shi’i authority is thus not a zero-sum game.

This chapter first presents an explicitly evolutionary model of the emergence of coordination in modern households. The chapter shows why certain conditions might favor market labor for one gender and home labor for the other. The goal is to provide a proof of concept for the usefulness of evolutionary models in this domain, as opposed to traditional game theoretic models. The chapter also argues that once these patterns have emerged, they should be relatively stable in the face of changing social conditions. Using these patterns of coordination as a starting point, the chapter then shows why emerging patterns of household bargaining, i.e., over who does more total work, and has more total leisure time, should favor whichever gender tends to be employed in market work.

How did southern China figure in Beijing, the Qing capital? Here “the South” (Jiangnan) must be understood as a cultural rather than geographical term. It does not, however, merely refer to the cultural space in which intellectuals gathered but, rather, to their lifestyle and spiritual existence typical of the elites who resided in regions south of the Yangzi River. This sense of the South involved the body, sense, memory, and everyday experience of Han culture in this period. Using Foucault’s notion of the “body politic,” I consider the South in opposition to macro politics, the Qing regime, which carried out society’s disciplinary and punishment functions. The body politic is a kind of “micro power,” which can sometimes override or undermine macro politics. In the process of accepting discipline and punishment from the Qing court, the South, drifting northward as its most talented men arrived to serve the Qing, was able to penetrate and reshape national politics in Beijing. In this sense, it maintained a measure of influence even in the face of hostile macro politics. To unpack the interaction between macro politics and micro politics, this article explores how the southern literati migrated to Beijing and established cultural circles there; how southern literati rewrote the idea of the “South” in the North and turned its remembrance into textual, physical, and spiritual rituals; and finally, how the South and the inscribing of the South, either in text or in action, served as a mode of existence for Chinese elites. I consider how intellectuals maintained or created links to the old culture by extending the South into the real spaces of the North and, more importantly, into their psychology.

AbstractThe evolution of ecological specialization can be summed up in a single question: why would a species evolve a more-restricted niche space? Various hypotheses have been developed to explain the promotion or suppression of ecological specialization. One hypothesis, competitive diversification, states that increased intraspecific competition will cause a population to broaden its niche breadth. With individuals alike in resource use preference, more individuals reduce the availability of preferred resources and should grant higher fitness to those that use secondary resources. However, recent studies cast doubt on this hypothesis with increased intraspecific competition reducing niche breadth in some systems. We present a game-theoretic evolutionary model showing greater ecological specialization with intraspecific competition under specific conditions. This is in contrast to the competitive diversification hypothesis. Our analysis reveals that specialization can offer a competitive advantage. Largely, when facing weak competition, more specialized individuals are able to acquire more of the preferred resources without greatly sacrificing secondary resources and therefore gain higher fitness. Only when competition is too great for an individual to significantly affect resource use will intraspecific competition lead to an increased niche breadth. Other conditions, such as a low diversity of resources and a low penalty to specialization, help promote ecological specialization in the face of intraspecific competition. Through this work, we have been able to discover a previously unseen role that intraspecific competition plays in the evolution of ecological specialization.

Any description of an ecosystem necessarily ignores some details of the underlying diversity. What predictions can be robust to such omissions? Here, building on the theoretical framework of resource competition, we introduce an eco-evolutionary model that allows organisms to be described at an arbitrary, potentially infinite, level of detail, enabling us to formally study the hierarchy of possible coarse-grained descriptions. Within this model, we demonstrate that a coarse-graining scheme may enable ecological predictions despite grouping together functionally diverse strains. However, this requires two conditions: the strains we study must remain in a diverse ecological context, and this diversity must be derived from a sufficiently similar environment. Our model suggests that studying individual strains of a species away from their natural eco-evolutionary context may eliminate the very reasons that make a species-level characterization an adequate coarse-graining of the natural diversity.

This qualitative research analyzes the complexities for Pakistan regarding Saudi-Iran relationships. Saudi Arabia has serious reservations regarding asymmetric power and regional ambitions of Iran along with its alleged pursuit of nuclear weapons. A particular concern founded in Riyadh is the challenge to the legitimacy of the AlSaud family in the face of regional and domestic audiences by upstaging it on Pan-Arab issues especially after 1979. Pakistan has a long history of close relationship with Iran as an immediate neighbor and Saudi Arabia as an extremely crucial strategic partner. These worst bilateral relations between the two regional rivals left limited choices for Islamabad. Though Pakistan tried hard to create a balance between both, yet Pakistan found it very difficult to maintain that balance, as both the rivals are stuck in a security dilemma and zero sum game, where victory or benefit of one is the loss for the other and a friend of one is perceived an enemy by the other.

AbstractInformation can be perceived from a multiplicity of spatial perspectives, which is central to effectively understanding and interacting with our environment and other people. Sensory impairments such as blindness are known to impact spatial representations and perspective-taking is often thought of as a visual process. However, disturbed functioning of other sensory systems (e.g., vestibular, proprioceptive and auditory) can also influence spatial perspective-taking. These lines of research remain largely separate, yet together they may shed new light on the role that each sensory modality plays in this core cognitive ability. The findings to date reveal that spatial cognitive processes may be differently affected by various types of sensory loss. The visual system may be crucial for the development of efficient allocentric (object-to-object) representation; however, the role of vision in adopting another’s spatial perspective remains unclear. On the other hand, the vestibular and the proprioceptive systems likely play an important role in anchoring the perceived self to the physical body, thus facilitating imagined self-rotations required to adopt another’s spatial perspective. Findings regarding the influence of disturbed auditory functioning on perspective-taking are so far inconclusive and thus await further data. This review highlights that spatial perspective-taking is a highly plastic cognitive ability, as the brain is often able to compensate in the face of different sensory loss.

Darwin was firmly of the opinion that biotic interactions, such as competition for food and space – the ‘struggle for existence’ – were of considerably greater importance in promoting evolution and extinction than changes in the physical environment. This is clearly brought out by this quotation from The Origin of Species: . . . Species are produced and exterminated by slowly acting causes . . . and the most important of all causes of organic change is one that is almost independent of altered . . . physical conditions, namely the mutual relation of organism to organism – the improvement of one organism entailing the improvement or extermination of others. . . . The driving force of competition in a crowded world is also stressed in another quotation presenting Darwin’s famous wedge metaphor: . . . In looking at Nature, it is most necessary . . . never to forget that every single organic being around us may be said to be striving to the utmost to increase in numbers; that each lives by a struggle at some period of its life; that heavy destruction inevitably falls either on the young or the old, during each generation . . . The face of Nature may be compared to a yielding surface, with ten thousand sharp wedges packed close together and driven inwards by incessant blows, sometimes one wedge being struck, and then another with greater force. . . . The implication of the Darwinian view concerning the dominance of biotic competition is that for each winner there is a loser – a kind of zero-sum game. It has been accepted more or less uncritically by generations of evolutionary biologists, but not until the 1970s did it become graced with a name – the Red Queen hypothesis. The story behind the emergence of this name is an interesting one. At the beginning of the 1970s the rather eccentric University of Chicago palaeobiologist Leigh Van Valen did some interesting research concerning the analysis of survivors of Phanerozoic taxa which suggested that the probability of a fossil group becoming extinct was more or less constant in time. To account for this, Van Valen put forward his Red Queen hypothesis.
