The Impact of Settlement Design on Tropical Deforestation Rates and Resulting Land Cover Patterns

Policymakers in the Brazilian Amazon face the challenge of meeting environmental and developmental goals as cities and towns within these tropical forests continue to face migration pressure. Alternative government planning strategies have been implemented to address forest clearing in conjunction with meeting social agendas. This paper uses panel estimation methods to investigate the impact of settlement design on land use. Results indicate that new settlement designs developed to further social interaction have had a negative impact on land cover and land use transformation. Thus, while new settlement designs appear to positively impact stated social goals, including greater contact between families and access to water and services, these social advances have come at the expense of environmental goals.deforestation, land use/land cover change, smart growth, settlement design, Amazon, Brazil, Environmental Economics and Policy, Land Economics/Use,

Speech Acts: The Contemporary Theoretical Landscape

What makes it the case that an utterance constitutes an illocutionary act of a given kind? This is the central question of speech-act theory. Answers to it—i.e., theories of speech acts—have proliferated. Our main goal in this chapter is to clarify the logical space into which these different theories fit. We begin, in Section 1, by dividing theories of speech acts into five families, each distinguished from the others by its account of the key ingredients in illocutionary acts. Are speech acts fundamentally a matter of convention or intention? Or should we instead think of them in terms of the psychological states they express, in terms of the effects that it is their function to produce, or in terms of the norms that govern them? In Section 2, we take up the highly influential idea that speech acts can be understood in terms of their effects on a conversation’s context or “score”. Part of why this idea has been so useful is that it allows speech-act theorists from the five families to engage at a level of abstraction that elides their foundational disagreements. In Section 3, we investigate some of the motivations for the traditional distinction between propositional content and illocutionary force, and some of the ways in which this distinction has been undermined by recent work. In Section 4, we survey some of the ways in which speech-act theory has been applied to issues outside semantics and pragmatics, narrowly construed

Wittgenstein’s influence on Austin’s philosophy of language

Many philosophers have assumed, without argument, that Wittgenstein influenced Austin. More often, however, this is vehemently denied, especially by those who knew Austin personally. We compile and assess the currently available evidence for Wittgenstein’s influence on Austin’s philosophy of language. Surprisingly, this has not been done before in any detail. On the basis of both textual and circumstantial evidence we show that Austin’s work demonstrates substantial engagement with Wittgenstein’s later philosophy. In particular, Austin’s 1940 paper, ‘The Meaning of a Word’, should be construed as a direct response to and development of ideas he encountered in Wittgenstein’s Blue Book. Moreover, we argue that Austin’s mature speech-act theory in How to Do Things with Words was also significantly influenced by Wittgenstein

Damaged Goods: A resource depletion model of addictive consumption

Economic research on the consumption of harmful goods focuses principally on the addictive nature of consumption rather than its impacts on health, despite medical research showing that consumers primarily consider health effects when making decisions about addictive behaviour. In this paper, the standard rational addiction model is recast in terms of a resource depletion problem, where the resource in question is a depletable stock of health, and the time horizon is finite. Analysis of the prototype health depletion model finds two types of consumption path, one that is compatible with the results from rational addiction and one that is not. Several extensions to the prototype model are explored.Resource /Energy Economics and Policy,

If I Ruled the World: Putting Hip Hop on the Atlas

“If I Ruled the World: Putting Hip Hop on the Atlas” contends for a third wave of Global Hip Hop Studies that builds on the work of the first two waves, identifies Hip Hop as an African diasporic phenomenon, and aligns with Hip Hop where there are no boundaries between Hip Hop inside and outside of the United States. Joanna Daguirane Da Sylva adds to the cipha with her examination of Didier Awadi. Da Sylva\u27s excellent work reveals the ways in which Hip Hoppa Didier Awadi elevates Pan-Africanism and uses Hip Hop as a tool to decolonize the minds of African peoples. The interview by Tasha Iglesias and myself of members of Generation Hip Hop and the Universal Hip Hop Museum provides a primary source and highlights two Hip Hop organizations with chapters around the world. Mich Yonah Nyawalo’s Negotiating French Muslim Identities through Hip Hop details Hip Hop artists Médine and Diam’s, who are both French and Muslim, and whose self-identification can be understood as political strategies in response to the French Republic’s marginalization of Muslims. In “Configurations of Space and Identity in Hip Hop: Performing ’Global South’,” Igor Johannsen adds to this special issue an examination of the spatiality of the Global South and how Hip Hoppas in the Global South oppose global hegemony. The final essay, “‘I Got the Mics On, My People Speak’: On the Rise of Aboriginal Australian Hip Hop,” by Benjamin Kelly and Rhyan Clapham, provides a thorough analysis of Aboriginal Hip Hop and situates it within postcolonialism. Overall, the collection of these essays points to the multiple identities, political economies, cultures, and scholarly fields and disciplines that Hip Hop interacts with around the world

Carbon-13 nuclear magnetic resonance spectra and mechanism of bridge–terminal carbonyl exchange in di-µ-carbonyl-bis[carbonyl(η-cyclopentadienyl)iron](Fe–Fe)[{(η-C5H5)Fe(CO)2}2]; cd-di-µ-carbonyl-f-carbonyl-ae-di(η-cyclopentadienyl)-b-(triethyl -phosphite)di-iron(Fe–Fe)[(η-C5H5)2Fe2(CO)3P(OEt)3], and some related complexes

A mechanism involving carbonyl-bridge breaking, rotation about the Fe–Fe bond, and bridge reformation is shown to account qualitatively for changes in the carbonyl region of the 13C n.m.r spectrum of the complex [(cp)(OC)[graphic omitted]e(cp){P(OEt)3}] and quantitatively for [(cp)(OC)[graphic omitted]e(CO)(cp)](cp =η-cyclopentadienyl).The activation energy for this process, 49.0 ± 4 kJ mol^–1(11.7 ± 1 kcal mol^–1), is close to that reported for cis–trans-isomerization of the cp groups, in accord with this mechanism. Variable-temperature 13C n.m.r. spectra of the complexes [(cp)(OC)[graphic omitted]u(CO)(cp)] and [(cp)(OC)[graphic omitted]i(cp)] are also reported

Problematising home education: challenging ‘parental rights’ and 'socialisation'

In the UK, Home Education, or home-schooling, is an issue that has attracted very little public, governmental or academic attention. Yet the number of children home educated is steadily increasing and has been referred to as a 'quiet revolution'. This article neither celebrates nor denigrates home educators, its aim, rather, is to identify and critically examine the two dominant discourses that define the way in which the issue is currently understood. First, the legal discourse of parental rights, which forms the basis of the legal framework, and secondly a psychoanalytical/common-sense 'socialisation' discourse within which school attendance is perceived as necessary for healthy child development. Drawing on historical, doctrinal human rights and psychoanalytical sources and post-structural and feminist perspectives, this article suggests that both discourses function as alternative methods of governance and that the conflicting ‘rights claims’ of parents and children obscure public interests and fundamental questions about the purpose of education

Against the Wind: Radio Light Curves of Type Ia Supernovae Interacting with Low-Density Circumstellar Shells

For decades, a wide variety of observations spanning the radio through optical and on to the x-ray have attempted to uncover signs of type Ia supernovae (SNe Ia) interacting with a circumstellar medium (CSM). The goal of these studies is to constrain the nature of the hypothesized SN Ia mass-donor companion. A continuous CSM is typically assumed when interpreting observations of interaction. However, while such models have been successfully applied to core-collapse SNe, the assumption of continuity may not be accurate for SNe Ia, as shells of CSM could be formed by pre-supernova eruptions (novae). In this work, we model the interaction of SNe with a spherical, low density, finite-extent CSM and create a suite of synthetic radio synchrotron light curves. We find that CSM shells produce sharply peaked light curves, and identify a fiducial set of models that all obey a common evolution and can be used to generate radio light curves for interaction with an arbitrary shell. The relations obeyed by the fiducial models can be used to deduce CSM properties from radio observations; we demonstrate this by applying them to the non-detections of SN 2011fe and SN 2014J. Finally, we explore a multiple shell CSM configuration and describe its more complicated dynamics and resultant radio light curves.Comment: 15 pages, 11 figures, ApJ accepte
