Wrestling Sprawl to the Ground: Defining and measuring an elusive concept

Abstract

The literature on urban sprawl confuses causes, consequences, and conditions. This article presents a conceptual definition of sprawl based on eight distinct dimensions of land use patterns: density, continuity, concentration, clustering, centrality, nuclearity mixed uses, and proximity. Sprawl is defined as a condition of land use that is represented by low values on one or more of these dimensions.

Each dimension is operationally defined and tested in 13 urbanized areas. Results for six dimensions are reported for each area, and an initial comparison of the extent of sprawl in the 13 areas is provided. The test confirms the utility of the approach and suggests that a clearer conceptual and operational definition can facilitate research on the causes and consequences of sprawl.     

The ‘girl effect’: liberalism,empowerment and the contradictions of development

The ‘girl effect’ – the idea that investment in the skills and labour of young women is the key to stimulating economic growth and reducing poverty in the global South – has recently become a key development strategy of the World Bank, the imf, usaid and dfid, in partnership with corporations such as Nike and Goldman Sachs. This paper examines the logic of this discourse and its stance towards kinship in the global South, situating it within the broader rise of ‘gender equality’ and ‘women’s empowerment’ as development objectives over the past two decades. Empowerment discourse, and the ‘capability’ approach on which it is based, has become popular because it taps into ideals of individual freedom that are central to the Western liberal tradition. But this project shifts attention away from more substantive drivers of poverty – structural adjustment, debt, tax evasion, labour exploitation, financial crisis, etc – as it casts blame for underdevelopment on local forms of personhood and kinship. As a result, women and girls are made to bear the responsibility for bootstrapping themselves out of poverty that is caused by external institutions – and often the very ones that purport to save them.

Report of the Law Reform Commission of Tanzania on Congestion in Prisons

Since its formal inauguration in the year 2006, the Caribbean Court of Justice (CCJ) has arguably shown itself to be quite capable of effectively dispensing with its overarching aims of consistency, coherence and legal certainty in the process of adjudication. Indeed, through the adoption of a teleological approach to the construction of the Revised Treaty of Chaguramas, the CCJ has positioned itself as a major operational component in the new Caribbean legal order, serving, as the European Court of Justice as well as several domestic courts have done, to ensure transparency and accountability. The court’s relatively nuanced purpose-driven approach has arguably been the single biggest contributing factor to the region’s quickly evolving ‘indigenous jurisprudence’. Nevertheless, some of the court’s most recent original jurisdiction decisions reveal a growing trend towards judicial restraint. The varying degrees to which the CCJ has adopted a teleological approach to the interpretation of the Revised Treaty of Chaguramas, the concomitant effects of this important development as well as the challenges which invariably arise in this connection are the subject of this article.     

Selective detection of trace nitroaromatic, nitramine, and nitrate ester explosive residues using a three-step fluorimetric sensing process: a tandem turn-off, turn-on sensor

Detection of trace quantities of explosive residues plays a key role in military, civilian, and counter-terrorism applications. To advance explosives sensor technology, current methods will need to become cheaper and portable while maintaining sensitivity and selectivity. The detection of common explosives including trinitrotoluene (TNT), cyclotrimethylenetrinitramine, cyclotetramethylene-tetranitramine, pentaerythritol tetranitrate, 2,4,6-trinitrophenyl-N-methylnitramine, and trinitroglycerin may be carried out using a three-step process combining "turn-off" and "turn-on" fluorimetric sensing. This process first detects nitroaromatic explosives by their quenching of green luminescence of polymetalloles (lambda em approximately 400-510 nm). The second step places down a thin film of 2,3-diaminonaphthalene (DAN) while "erasing" the polymetallole luminescence. The final step completes the reaction of the nitramines and/or nitrate esters with DAN resulting in the formation of a blue luminescent traizole complex (lambda(em) = 450 nm) providing a "turn-on" response for nitramine and nitrate ester-based explosives. Detection limits as low as 2 ng are observed. Solid-state detection of production line explosives demonstrates the applicability of this method to real world situations. This method offers a sensitive and selective detection process for a diverse group of the most common high explosives used in military and terrorist applications today.
