Understanding everyday behavior relies heavily upon understanding our ability to improvise, how we are able to continuously anticipate and adapt in order to coordinate with our environment and others. Here we consider the ability of musicians to improvise, where they must spontaneously coordinate their actions with co-performers in order to produce novel musical expressions. Investigations of this behavior have traditionally focused on describing the organization of cognitive structures. The focus, here, however, is on the ability of the time-evolving patterns of (...) inter-musician movement coordination as revealed by the mathematical tools of complex dynamical systems to provide a new understanding of what potentiates the novelty of spontaneous musical action. We demonstrate this approach through the application of cross wavelet spectral analysis, which isolates the strength and patterning of the behavioral coordination that occurs between improvising musicians across a range of nested time-scales. Revealing the sophistication of the previously unexplored dynamics of movement coordination between improvising musicians is an important step towards understanding how creative musical expressions emerge from the spontaneous coordination of multiple musical bodies.

Musical improvisation is a natural case of human pattern formation, and Walton and colleagues investigate the way that different contextual constraints affect patterns of improvisation and their aesthetic quality. The authors find that coordination patterns are more diversified between two musicians when the musical space in which to improvise is relatively more constrained. They also find that listeners experience more diversified, complementary patterns between musicians as more enjoyable and harmonious.

This paper discusses the idea that trade – the practice of regularised exchange of goods or services between nation-states for mutual advantage under an orchestrated system of rules – can generate moral duties, duties that exist between only participants in the activity. It considers this idea across three duties often cited as duties of trade: duties not to harm; duties to provide certain basic goods; and duties to distribute benefits and burdens fairly. The paper argues that these three duties seem (...) unlikely contenders for duties thought in some sense to supervene on trade, the former two because they seem to exist regardless of the existence of trade and the latter because it seems to apply to a group more widely conceived than to be coherently thought centred on trade. It concludes that, at least across these three duties, it is more plausible to think that they are duties which, although possibly having relevance for how trade is conducted, do not emerge from the practice and are, rather, grounded elsewhere.

This article contributes to normative debates about residential segregation and its relationship to inequality. It defends a position often disregarded in literature: that there is merit to advancing residential integration through some scenarios where advantaged individuals move to disadvantaged areas. It develops this case in dialogue with three other views. In relation to advocates of addressing the inequalities of residential segregation through redistribution, it defends integration as a means of tackling social and political factors that sustain injustice. It challenges those (...) who defend relocating disadvantaged individuals to advantaged areas by highlighting the burdens and demand for cultural assimilation this imposes on the disadvantaged. It considers the worry that advantaged individuals relocating to disadvantaged areas harbours the problematic features of gentrification. It responds that these concerns, while important in some cases, do not arise in all scenarios of this kind. (shrink)

In this article I consider two consequentialist positions on whether individuals in affluent countries ought to purchase Fair Trade goods. One is a narrow argument, which asserts that individuals should purchase Fair Trade goods because this will have positive direct effects on poverty reduction, by, for example, channelling money into development. I argue that this justification is insufficient to show that individuals should purchase Fair Trade goods because individuals could achieve similar results by donating money to charity and, therefore, without (...) purchasing Fair Trade goods. The second position has a wider focus. It notes both the direct effects of purchasing Fair Trade goods and possible indirect effects, such as the impact this might have on other individuals. I argue that certain actions, of which Fair Trade is one example, will be more likely to encourage individuals who would not otherwise contribute to poverty reduction to contribute and that this may produce additional positive value. Although space prohibits specific conclusions about Fair Trade, I note that considerations of this kind could give us reason to purchase such goods beyond those that issue from the direct effects of doing so and that, as such, they are crucial for determining whether individuals should purchase Fair Trade goods.

This note offers reflections on qualified market access —the practice of linking trade agreements to values such as human rights, labour standards, or environmental protection. This idea has been suggested by political theorists as a way of fulfilling our duties to the global poor and of making the global economic system more just, and it has influenced a number of concrete policies, such as European Union trade policies. Yet, in order to assess its merits tout court, different perspectives and disciplines (...) need to be brought together, such as international law, economics, political science, and philosophy. It is also worth reflecting on existing practices, such as those of the EU. This note summarises some insights about QMA by drawing such research together and considers the areas in which further research is needed, whilst reflecting also on the merits of interdisciplinary exchanges on such topics.

This paper discusses what type of sociological context is appropriate for Rawls’ ‘property-owning democracy’. Following certain suggestions offered by Rawls and in the work of Joshua Cohen, it explores, in particular, the kind of fraternity and social interaction suitable for citizens in Rawlsian society and the role of the state in engineering these bonds. Utilising a normative framework based on Rawls’ discussion of a property-owning democracy and various data sets, the paper argues that bonds of social trust, active participation in (...) trade unions and enrolment in public schools, and the use of state policy to organise a mixture of public, cooperative, and private economic institutions would be suitable for a Rawlsian society to adopt because it appears that these structures are favourably connected to the ends of Rawlsian justice.

This paper defends the pertinence of global justice in the contemporary world. It accepts, for the sake of argument, Nagel's view that matters of justice arise only when political authority is asserted or exercised and, connectedly, his rejection of the cosmopolitan thesis. However, it challenges his conclusion that considerations of justice do not apply beyond the state. It argues that on any plausible account of the relationship between authority and justice international institutions, such as the World Trade Organisation, are now (...) authoritative in the right way to justify their evaluation from the point of view of justice.
