Entanglement and Sources of Magnetic Anisotropy in Radical Pair-Based Avian Magnetoreceptors

One of the principal models of magnetic sensing in migratory birds rests on the quantum spin-dynamics of transient radical pairs created photochemically in ocular cryptochrome proteins. We consider here the role of electron spin entanglement and coherence in determining the sensitivity of a radical pair-based geomagnetic compass and the origins of the directional response. It emerges that the anisotropy of radical pairs formed from spin-polarized molecular triplets could form the basis of a more sensitive compass sensor than one founded on the conventional hyperfine-anisotropy model. This property offers new and more flexible opportunities for the design of biologically inspired magnetic compass sensors

Flexible housing: the means to the end

How might flexible housing be achieved? 'Determinate' and 'indeterminate' approaches are examined using twentieth-century examples

Recessions and the Cost of Job Loss

We develop new evidence on the cumulative earnings losses associated with job displacement, drawing on longitudinal Social Security records for U.S. workers from 1974 to 2008. In present value terms, men lose an average of 1.4 years of pre-displacement earnings if displaced in mass-layoff events that occur when the national unemployment rate is below 6 percent. They lose a staggering 2.8 years of pre-displacement earnings if displaced when the unemployment rate exceeds 8 percent. These results reflect discounting at a 5% annual rate over 20 years after displacement. We also document large cyclical movements in the incidence of job loss and job displacement and present evidence on how worker anxieties about job loss, wage cuts and job opportunities respond to contemporaneous economic conditions. Finally, we confront leading models of unemployment fluctuations with evidence on the present value earnings losses associated with job displacement. The model of Mortensen and Pissarides (1994) extended to include search on the job generates present value losses only one-fourth as large as observed losses. Moreover, present value losses in the model vary little with aggregate conditions at the time of displacement, unlike the pattern in the data.

Flexible housing: opportunities and limits

Flexibility in housing design has social, economic and environmental advantages and yet is currently often ignored. The first of two papers sets out the history of this issue

IT Governance Mechanisms and Administration/IT Alignment in the Public Sector: A Conceptual Model and Case Validation

The mechanisms of information technology (IT) governance have been widely recognized as practices to sustain alignment of business and IT units. However, the IT governance literature so far has drawn little attention to the possible idiosyncrasies of governance arrangements in the public sector. In this paper we propose a conceptual model to investigate the relationship between IT governance mechanisms and according performance outcomes specifically for public sector organizations. A survey instrument is developed and validated based on in-depth interviews with IT representatives from three different municipalities in Germany. A cross-case analysis particularly provides evidence for the importance of structural and relational mechanisms and demonstrates how different mechanisms can compensate each other. Our findings provide relevant insights for government practitioners and an impetus for further research

The prevalence, influential factors and mechanisms of relative age effects in UK Rugby League.

Relative age effects (RAEs), reflecting observed inequalities in participation and attainment as a result of annual age-grouping policies in youth sport, are common in most team sports. The aims of this study were to determine if and when RAEs become apparent in Rugby League, determine how influential variables (e.g., gender) lead and clarify whether player retention at junior representative levels can explain persistent RAEs. Player data were collected for the male and female community games ranging from Under 7s to Senior (N=15,060) levels, junior representative selections (i.e., Regional) and professional players (N=298). Chi-square analyses found significant (P<0.05) uneven birth date distributions beginning at the earliest stages of the game and throughout into senior professionals. In junior representative selections, 47.0% of Regional and 55.7% of National representative players were born in Quartile 1, with RAE risk increasing with performance level. Gender and nationality were also found to moderate RAE risk. When tracking representative juniors, over 50% were retained for similar competition the following season. Findings clearly demonstrate that RAEs exist throughout Rugby League with early selection, performance level and retention processes, appearing to be key contributing factors responsible for RAE persistence

Adapting research activity: AHRC review of practice-led research

In 2005 the Arts and Humanities Research Council initiated a review of practice-led research in art, design and architecture. The purpose of the review was to develop a ‘comprehensive map of recent and current research activity in the area’. What quickly became obvious to the team that won the bid to run the review (led by the three authors) was that to map activity one first had to attempt to define it. The term ‘practice-led research’ means many different things to different people and so immediately raises debate. The positions range from those who believe that the act of making or designing alone constitutes research, to those who believe that research (as analytical activity) is incommensurable with design (as synthetic activity). For the former, the knowledge contained within the artefact is self-evident and beyond the need for additional explication; for the latter, knowledge resides outside the artefact and in the realm of its dissemination and interpretation. The importance of the AHRC review is not that it will settle these arguments, but that it will provide a much firmer context in which to place them
