Interview with Cedric Boeckx
No full textCedric Boeckx is a Research Professor at the Catalan Institute for Advanced Studies (ICREA), and a member of the Center for Theoretical Linguistics at the Universitat Autònoma de Barcelona. Most recently he was an Associate Professor of Linguistics at Harvard University. He is the author and editor of various books on syntax, minimalism and language (from a biolinguistic perspective). He is also the founding co-editor, with Kleanthes K. Grohmann, of the Open Access journal Biolinguistics. The interview came to fruition after we had the idea of asking various linguists the following question: "What is the right place for linguistics?". At first, we were looking for short, straightforward answers. The question soon proved to be hard to approach that way, and Prof. Cedric Boeckx was kind enough to accept our invitation for a more thorough elaboration on the subject, under the "Interview" section of our journal, which he generously granted us on November 7th, 2011, at the Faculty of Letters of the University of Porto, a day before his "Introduction to Biolinguistics" workshop, also there, and for which we are also very thankful. This text is a virtually word-for-word transcription of the recorded 2-hour long interview, subject only to minor revisions by our editorial team and some comments by the interviewee. We hope that the final result is of interest to students, researchers and people alike

Tax compliance perceptions and formalization of small businesses in south Africa
No full textThis paper is based on large-scale surveys of formal and informal small businesses in South Africa, including questions about their experiences and perceptions about tax compliance, tax morale, and related variables. The survey findings suggest that formalization is more likely to take place in urban areas, involving relatively larger firms, and those who already use proper bookkeeping. Informal firms who said they were likely to register for tax in the near future were more likely than other informal firms to report higher satisfaction with government services, and to believe most businesses pay their taxes. The most-cited advantages of being registered for tax included better access to government services, better access to financing, and better opportunities for growth.Taxation&Subsidies,Debt Markets,Emerging Markets,Tax Law,Fiscal Adjustment
Identity matters: inter- and intra-racial disparity and labor market outcomes
No full textStandard analysis of racial inequality incorporates racial classification as an exogenous binary variable. This approach obfuscates the importance of racial self-identity and clouds our ability to understand the relative importance of unobserved productivity-linked attributes versus market discrimination as determinants of racial inequality in labor market outcomes. Our examination of identity heterogeneity among African Americans suggests racial wage disparity is most consistent with weak colorism, while genotype disparity best describes racial employment differences. Further, among African Americans, the wage data are not consistent with the hypothesis that black-mixed race wage disparity can be explained by differences in unobserved productivity-linked productive attributes.racial discrimination, racial inequality, identity, African American, African Diaspora, wage discrimination, employment discrimination, Hispanic, acting white, multi-racial, skin shade
Inferring effective field observables from a discrete model
No full textAspin system on a lattice can usually be modeled at large scales by an effective quantum field theory. A key mathematical result relating the two descriptions is the quantum central limit theorem, which shows that certain spin observables satisfy an algebra of bosonic fields under certain conditions. Here, we show that these particular observables and conditions are the relevant ones for an observer with certain limited abilities to resolve spatial locations as well as spin values. This is shown by computing the asymptotic behaviour of a quantum Fisher information metric as function of the resolution parameters. The relevant observables characterise the state perturbations whose distinguishability does not decay too fast as a function of spatial or spin resolution.The author is grateful to Tobias Osborne for discussions leading to this work.

This is a very personal perspective on a concept of universal and future significance. It is personal, both is the sense that it is an unashamedly biased view of both the significance of the project, and the nature of that significance and because the author was personally involved as one of the consultants on GENERATOR and subsequently involved Cedric Price in its educational application at the Architectural Association. GENERATOR is still very much alive and was still developing whilst this chapter was being written.\u
Cedric Masey White and his solution to the pipe flow problem
No full text Cedric Masey White is a notable British hydraulician of the twentieth century, having particularly contributed to the pipe flow problem in collaboration with his PhD student Cyril Frank Colebrook. Their solution is currently accepted universally, although some particular questions remain as yet unresolved. This biographical work further introduces the professional background of White during his stays at King's College and Imperial College, London, where he became one of the most renowned British hydraulicians mainly because he introduced the post graduate course in hydraulics after World War II. This work also describes how the author was able to find White's daughter in Canada, and how she kindly gave her support in terms of photographs and biographical details. A well-known figure in the field of hydraulics is therefore finally given acknowledgement by an adequate biography. </jats:p
Cataglyphis laylae Cedric A. Collingwood & Donat Agosti & Mostafa R. Sharaf & Antonius van Harten 2011, nov. spec.
No full textCataglyphis laylae Collingwood nov. spec. Plates 96–103 Cataglyphis desertorum Forel, 1894, teste Collingwood, 1985; unavailable name according to Agosti (1990). Specimens examined: Holotype: 1 ☿, United Arab Emirates, al-Ain [24°13'N 55°46'E], iii.1995, leg. C.A. Collingwood (MHNG). Paratypes: 3 ☿, al-Ain zoo, 13.iii.2005, CAC. 1 ☿, Remah, 9.iii.1995, CCA. 3 ☿, Remah, resthouse, 250 m, irrigated sand dune [24°10'37"N 55°18'6"E], 18.iii.1995, leg. D. Agosti. 6 ☿, Remah, resthouse, 250 m, irrigated sand dune, nest with one entrance, [24°10'37"N, 55°18'6"E], 18.iii.1995, leg. D. Agosti. 1 ☿, Sharjah Desert Park, 5–6.x.2004, AvH; 1 ☿, 3.iii.2005, CAC. 1 ☿, al- Za'aba, 100 m, sandy soil with Rhaisa stricta [23°43'20"N, 55°33'49"E], 22.iii.1995, leg. D. Agosti. Description: A large worker from al-Ain was selected as holotype. The measurements are as follows: total length 8.40; head width 3.60; head length 4.20; scape length 3.84; funicular segment I 0.40; funicular segment II 0.23; petiole length 1.10; petiole width 0.72. Colour dark reddish brown. There are no exterior hairs on the scapes or hind tibia. The gaster, petiole and propodeum have dorsal hairs. Remarks: This species thought to correspond with C. desertorum has to be described as a new species. In fact it is one of the commonest Cataglyphis in southern Arabia. The main distinguishing feature compared with other dark Cataglyphis is the slender petiole, which has the anterior face more sloped than in other similar species such as C. niger (André, 1882) and C. savignyi (Dufour, 1862). Biology: Cataglyphus laylae nov. spec. does not appear to occur in open sandy desert and is most abundant in disturbed habitats such as man-developed plantations and open cultivated fields. Distribution: This species was recorded by Collingwood (1985) as C. desertorum from Saudi Arabia and Oman and as Cataglyphis spec. by Collingwood & Agosti (1996). Etymology: The new species is named after a village settlement called “Layla”, just north of Riyadh (Saudi Arabia) in the area where the author (CAC) first encountered it in numbers in an Acacia plantation.Published as part of Cedric A. Collingwood, Donat Agosti, Mostafa R. Sharaf & Antonius van Harten, 2011, Order Hymenoptera, family Formicidae, pp. 1-70 in Arthropod fauna of the UAE 4 on page 54, DOI: 10.5281/zenodo.116858
Cedric Price’s Pop-Up Parliament: A Role Model for Media Architecture and Data Politics
No full textThe digital era has supposedly had a drastic impact on contemporary forms of political debate. Live-tweets, podcasts, and posts have become the main channels for politics, polemics, and populism alike. But these tendencies are not only an acceleration of the politics of media brought about by the logics behind television, cybernetics, and computation in the post-war era. They gained strength when populist politics appropriated information access via mass media, which once promised the emancipation of ordinary citizens by architectural means through pop-culture.In this essay I seek to elaborate how Cedric Price’s 1965 design of the Pop-Up Parliament dealt with a media-technical condition of politics, while proposing that architecture was an integral part of the media network of governing. Price’s project is paradigmatic of the 1960s, a period when the media operations of information compression, prediction, and audience targeting became more decisive for politics than the content of debate. This analysis allows us, on the one hand, to problematise conventional definitions of populism towards a media-based concept, and on the other, to further our understanding of architecture as a political medium operating directly with media such as documents, television, and computers. This essay argues that the advent of digital media calls for a different architectural history of populism, one which engages with the operativity of media and cultural techniques, rather than relying upon the symbolic representation of ideology in architecture.History, Form & Aesthetic
