The practice of crime prevention: design principles for more effective security governance

South Africa has had a comprehensive crime prevention policy agenda for some time in the form of the 1996 National Crime Prevention Strategy and the 1998 White Paper on Safety and Security. Despite this, prevention has remained very much a second cousin within the South African criminal justice family, notwithstanding the fact that there is widespread agreement that it warrants far more attention. In this article we briefly review some of the principal obstacles to effective crime prevention. Our understanding of ‘crime prevention’ is a broad one – it involves simply asking the question: How can we reduce the likelihood of this happening again? This question opens up a range of preventative possibilities. Whether they are of a socio-economic, environmental or law enforcement nature depends on the nature of the (crime) problem. On the basis of our analysis, we propose three design principles to be followed if we, South Africans are to establish crime prevention as a central focus of our security governance. These design principles articulate what might be thought of as ‘best thinking’ rather than ‘best practice’

Governing-through-harm and public goods policing

Among scholars of law and crime and practitioners of public safety, there is a pervasive view that only the public police can or should protect the public interest. Further, the prevailing perception is that the public police predominantly governs through crime—that is, acts on harms as detrimental to the public good. We argue that governing harm through crime is not always the most effective way of producing public safety and security and that the production of public safety is not limited to public police forces. An approach of governing-through-harm that uses a variety of noncrime strategies and private security agents as participants in public safety is often more effective—and more legitimate—than the predominant governing-through-crime approach. We reflect on case studies of noncrime intervention strategies from the Global South to bolster the case for decoupling the link between the public police and public goods. A new theoretical framing needs to be pursued

A Terraced Scanning Superconducting Quantum Interference Device Susceptometer with Sub-Micron Pickup Loops

Superconducting Quantum Interference Devices (SQUIDs) can have excellent spin sensitivity depending on their magnetic flux noise, pick-up loop diameter, and distance from the sample. We report a family of scanning SQUID susceptometers with terraced tips that position the pick-up loops 300 nm from the sample. The 600 nm - 2 um pickup loops, defined by focused ion beam, are integrated into a 12-layer optical lithography process allowing flux-locked feedback, in situ background subtraction and optimized flux noise. These features enable a sensitivity of ~70 electron spins per root Hertz at 4K.Comment: See http://stanford.edu/group/moler/publications.html for an auxiliary document containing additional fabrication details and discussio

Criminology: some lines of flight

The 40th Anniversary Edition of Taylor, Walton and Young’s New Criminology, published in 2013, opened with these words: ‘The New Criminology was written at a particular time and place, it was a product of 1968 and its aftermath; a world turned upside down’. We are at a similar moment today. Several developments have been, and are turning, our 21st century world upside down. Among the most profound has been the emergence of a new earth, that the ‘Anthropocene’ references, and ‘cyberspace’, a term first used in the 1960s, which James Lovelock has recently termed a ‘Novacene’, a world that includes both human and artificial intelligences. We live today on an earth that is proving to be very different to the Holocene earth, our home for the past 12,000 years. To appreciate the Novacene one need only think of our ‘smart’ phones. This world constitutes a novel domain of existence that Castells has conceived of as a terrain of ‘material arrangements that allow for simultaneity of social practices without territorial contiguity’ – a world of sprawling material infrastructures, that has enabled a ‘space of flows’, through which massive amounts of information travel. Like the Anthropocene, the Novacene has brought with it novel ‘harmscapes’, for example, attacks on energy systems. In this paper, we consider how criminology has responded to these harmscapes brought on by these new worlds. We identify ‘lines of flight’ that are emerging, as these challenges are being met by criminological thinkers who are developing the conceptual trajectories that are shaping 21st century criminologies

Polycentric security governance and sustainable development in the Global South

Policing in much of the developing world has always been, in many respects, both dominated by the nonstate and pluralised. Yet, plurality and the nonstate are predominantly conceptualised, by scholars and practitioners alike, as problematic, noninclusive and/or undemocratic. Yet the reality is far more complex than this. In this chapter, we turn the tables on conventional wisdom by looking to the positive features of plural or polycentric forms of security governance by asking how these features might be utilised to provide for more inclusive forms of security governance in the Global South. Drawing on empirical research in South Africa on plural policing arrangements, this chapter considers how Sustainable Development Goal 16 which seeks to ‘promote peaceful and inclusive societies’ might be realised within plural governance systems. This chapter seeks to demonstrate that certain conditions need to be in place for plural or polycentric systems of security governance to coprovide effective and inclusive security for the collective good and, furthermore, that the positive features of the nonstate can be harnessed to give effect to the SDGs

‘Everything-old-is-new-again’: private urban security governance responses to new harmscapes

This article reflects on the proliferation of novel forms of private urban security governance assemblages, specifically the roles of private auspices and providers in responding to contemporary climate-related socio-material harmscapes. The authors use the lens of climatic harms and associated discursive shifts in understandings of the relationship between humans and ‘nature’ to draw attention to gating adaptations, assemblages of powers and capacities being mobilised in response to emerging harmscapes, the logics and technologies underpinning these developments, the roles of established security agents and novel security professionals and the use of resilience as a conceptual framing. These security governance ventures are conceived of as mutating private urban security governance vestiges from PUSG 1.0 to PUSG 2.0 and in this regard, ‘climate gating’ is used as an emblematic example in exploring PUSG 2.0

Variation in Sex Allocation and Floral Morphology in an Expanding Distylous Plant Hybrid Complex

Premise of research. Sex allocation, the relative energy devoted to producing pollen, ovules, and floral displays, can significantly affect reproductive output and population dynamics. In this study, we investigated floral morphology and gamete production in bisexual, distylous plants from a self-incompatible hybrid complex (Piriqueta cistoides ssp. caroliniana Walter [Arbo]; Turneraceae). Sampling focused on two parent types (C, V) and their stable hybrid derivative (H). Since H morphotypes are heterotic for growth and fruit production, we hypothesized that they would produce larger flowers with more gametes. We also anticipated that plants with long styles (long morphs) would produce less pollen than short morphs, since long-morph pollen is larger. Methodology. Over two consecutive summers, flowers were collected from 1465 individual plants in 28 field populations. Floral parameters were measured digitally, and each flower’s pollen number, ovule number, and stigma-anther separation was quantified under a dissecting microscope. Gamete production (n = 332) and stigma-anther separation (n = 119) were also quantified for plants from a greenhouse accession. Pivotal results. Floral display differed among morphotypes, with H plants producing the largest flowers and C plants displaying the least petal separation. Hybrid morphotypes produced significantly more pollen than parental morphotypes, and pollen quantity was significantly greater for long morphs. Ovule production, however, was greatest for V flowers. Stigma-anther separation differed between years and style morphs (greater for short morphs) but not among morphotypes or within a single season. Conclusions. Differences in pollen production between morphs were not consistent with trade-offs in pollen size and number or selection for increased male function in short morphs. Greater stigma-anther separation in short morphs supported the hypothesis of selection to reduce pollen interference. Enhanced floral display and pollen production followed other heterotic traits observed in H morphotypes. The superior ability of H morphotypes to attract pollinators and sire seeds might partially explain this hybrid zone’s continuing expansion

Adolescents' views of food and eating: Identifying barriers to healthy eating

This is a postprint version of the article. The official published version can be accessed from the link below - © 2006 The Association for Professionals in Services for Adolescents Published by Elsevier Ltd.Contemporary Western society has encouraged an obesogenic culture of eating amongst youth. Multiple factors may influence an adolescent's susceptibility to this eating culture, and thus act as a barrier to healthy eating. Given the increasing prevalence of obesity amongst adolescents, the need to reduce these barriers has become a necessity. Twelve focus group discussions of single-sex groups of boys or girls ranging from early to-mid adolescence (N = 73) were employed to identify key perceptions of, and influences upon, healthy eating behaviour. Thematic analysis identified four key factors as barriers to healthy eating. These factors were: physical and psychological reinforcement of eating behaviour; perceptions of food and eating behaviour; perceptions of contradictory food-related social pressures; Q perceptions of the concept of healthy eating itself. Overall, healthy eating as a goal in its own right is notably absent from the data and would appear to be elided by competing pressures to eat unhealthily and to lose weight. This insight should inform the development of future food-related communications to adolescents.
