Consumer culture and the commodification of policing and security

Abstract: This paper sets out to make sociological sense of some contemporary trends in the consumption of policing services and security products. I argue that the commodification of policing and security can fruitfully be theorised and investigated in terms of the spread of consumer culture, a contention that I demonstrate in three (related) ways. I begin by examining how a culture of consumption is pervading the practices and rhetoric of the public police and outlining the impact of `consumerism' on lay sensibilities towards policing. I then set out some prevailing trends in the consumption of protective services and hardware and consider the effects of a burgeoning `security market' on the construction of authority, subjectivity and social relations. Finally, I detail a number of possible points of resistance to the spread of commercially-delivered policing and security and argue that these provide both some potential cultural limits to the extension of a `consumer attitude' in this field, and a space within wh...

A review of ant cuticular hydrocarbons.

Abstract: We compared the published cuticular hydrocarbon (CHC) profiles of 78 ant species across 5 subfamilies. Almost 1,000 CHCs have been described for these species, composing 187 distinct homologous series and ten hydrocarbon groups. In descending order of occurrence were: n-alkanes > monomethylalkanes > dimethylalkanes > alkenes > dienes>> trimethylalkanes>> methylalkenes > methylalkadienes > trienes > tetramethylalkanes. Odd chain lengths and positions of methyl or double bonds at odd carbon numbers were far more numerous than even chain-length compounds or bond positions. Although each species possess its own unique pattern of CHCs, we found no association between CHC profile and phylogeny. The production of the biosynthetically complex compounds (e.g., methyl branched dienes) by the most primitive living ant suggests that the basic genetic architecture required to produce the rich diversity of CHCs was already present prior to their adaptive radiation. Unlike the ubiquitous n-alkanes and monomethylalkanes, there is a huge diversity of species-specific dimethylalkanes that makes them likely candidates for species and nest-mate discrimination signals.

Temporal Aggregation and the Power of Cointegration Tests: a Monte Carlo Study*

Abstract: The effect of time-aggregation on the power of commonly used tests for cointegration is studied with the Monte Carlo method. The results suggest that, for a given span, a higher frequency of observation can add substantially to test power. Also, Engle and Granger's (1987) ADF test leads overall to the highest and most stable powers for typical finite sample sizes and likely data generating processes encountered by practitioners.

Computer Simulation Studies of Strontium Titanate

Abstract: We present the results of computer simulation studies of SrTiO3. After deriving a reliable potential model, we concentrate on the properties of defects and dopants. Our calculations are used to propose a defect model that is consistent with experimental observations. For vacancy disorder, the calculations show that SrTiO3 (Schottky) and SrO (Schottky-like) disorder have very similar energy, with a small tendency for the development of Sr deficiency at higher temperatures. All mono- and divalent cations prefer to substitute at strontium sites. For trivalent cations, three types of mechanism (Sr and Ti substitution and self-compensation) are proposed, whereas for tetravalent cations substitution on both A and B sites may occur, depending on the ionic radius.
