Atomic level micromagnetic model of recording media switching at elevated temperatures

An atomic level micromagnetic model of granular recording media is developed and applied to examine external field-induced grain switching at elevated temperatures which captures non-uniform reversal modes. The results are compared with traditional methods which employ the Landau-Lifshitz-Gilbert equations based on uniformly magnetized grains with assigned intrinsic temperature profiles for $M(T)$ and $K(T)$. Using nominal parameters corresponding to high-anisotropy FePt-type media envisioned for Energy Assisted Magnetic Recording, our results demonstrate that atomic-level reversal slightly reduces the field required to switch grains at elevated temperatures, but results in larger fluctuations, when compared to a uniformly magnetized grain model.Comment: 4 pages, 5 figure

Learning from the history of disaster vulnerability and resilience research and practice for climate change

Humanity has long sought to explain and understand why environmental processes and phenomena contribute to and interfere with development processes, frequently through the terms and concepts of ‘vulnerability’ and ‘resilience’. Many proven ideas and approaches from development and disaster risk reduction literature are not fully considered by contemporary climate change work. This chapter describes the importance of older vulnerability and resilience research for contemporary investigations involving climate change, suggesting ways forward without disciplinary blinkers. Vulnerability and resilience as processes are explored alongside critiques of the post-disaster ‘return to normal’ paradigm. The importance of learning from already existing literature and experience is demonstrated for ensuring that complete vulnerability and resilience processes are accounted for by placing climate change within other contemporary development concerns

Modelling the effect of seasonal influenza vaccination on the risk of pandemic influenza infection

<p>Abstract</p> <p>Background</p> <p>Recent studies have suggested that vaccination with seasonal influenza vaccine resulted in an apparent higher risk of infection with pandemic influenza H1N1 2009. A simple mathematical model incorporating strain competition and a hypothesised temporary strain-transcending immunity is constructed to investigate this observation. The model assumes that seasonal vaccine has no effect on the risk of infection with pandemic influenza.</p> <p>Results</p> <p>Results of the model over a range of reproduction numbers and effective vaccination coverage confirm this apparent increased risk in the Northern, but not the Southern, hemisphere. This is due to unvaccinated individuals being more likely to be infected with seasonal influenza (if it is circulating) and developing hypothesised temporary immunity to the pandemic strain. Because vaccinated individuals are less likely to have been infected with seasonal influenza, they are less likely to have developed the hypothesised temporary immunity and are therefore more likely to be infected with pandemic influenza. If the reproduction number for pandemic influenza is increased, as it is for children, an increase in the apparent risk of seasonal vaccination is observed. The maximum apparent risk effect is found when seasonal vaccination coverage is in the range 20-40%.</p> <p>Conclusions</p> <p>Only when pandemic influenza is recently preceded by seasonal influenza circulation is there a modelled increased risk of pandemic influenza infection associated with prior receipt of seasonal vaccine.</p

Trends in sexually transmitted infections in general practice 1990-2000: population based study using data from the UK general practice research database

Objective: To describe the contribution of primary care to the diagnosis and management of sexually transmitted infections in the United Kingdom, 1990-2000, in the context of increasing incidence of infections in genitourinary medicine clinics. Design: Population based study. Setting: UK primary care. Participants: Patients registered in the UK general practice research database. Main outcome measures: Incidence of diagnosed sexually transmitted infections in primary care and estimation of the proportion of major such infections diagnosed in primary care. Results: An estimated 23.0% of chlamydia cases in women but only 5.3% in men were diagnosed and treated in primary care during 1998-2000, along with 49.2% cases of non-specific urethritis and urethral discharge in men and 5.7% cases of gonorrhoea in women and 2.9% in men. Rates of diagnosis in primary care rose substantially in the late 1990s. Conclusions: A substantial and increasing number of sexually transmitted infections are diagnosed and treated in primary care in the United Kingdom, with sex ratios differing from those in genitourinary medicine clinics. Large numbers of men are treated in primary care for presumptive sexually transmitted infections

Recreation value of a new long-distance walking track

A large recreation value may be expected for a long-distance walking track which allows for hiking and camping in a tropical rainforest environment. When such a resource is new, sufficient data are not available for a primary study. A practical way to obtain a value estimate is by employing benefit transfer procedures. Using a travel cost analysis for the Thorsborne Trail as the transfer source, a consumer surplus estimate for the new Cannabullen Track was estimated at about Aus$300 per person per year. This value may contribute to management decisions about further development of facilities along the track and about user fees

Individuals' fixed digital mindset, internal HRM alignment and feelings of helplessness in virtual teams

Purpose The present study investigates whether individuals having a fixed digital mindset (comprises fundamental beliefs about technological ability and organizational resources as work becomes more digitalized) experience greater helplessness working in virtual teamwork environments. The authors examine how perceived internal human resource management (HRM) alignment moderates the positive relationship expected between individuals' fixed digital mindset and feelings of helplessness. Together, the paper aims to contribute to a greater understanding of the personal and contextual factors that influence an individual's experience of helplessness in virtual team settings. Design/methodology/approach The authors test the hypotheses using time-lagged survey data collected from 153 information technology (IT) engineers working in virtual teams in Europe. Findings The authors find that individuals with higher levels of fixed digital mindset experience greater helplessness in virtual teamwork environments than individuals with lower levels. Furthermore, the authors find that having higher-fixed beliefs about organizational resources is positively related to helplessness when individuals perceive that the broader HRM system is misaligned with the virtual teamwork environment. Research limitations/implications The data were obtained from IT engineers in Europe, which is potentially limiting the generalizability of the authors' findings to other work contexts and cultures. Practical implications The authors' study helps leaders in virtual teamwork environments to better understand and manage the personal and contextual factors that could affect individuals' well-being and effective functioning in such settings. Originality/value The authors' research contributes to the scant literature investigating the personal characteristics important in virtual teamwork environments and the contextual factors important for aligning virtual teamwork designs with the organizational system. The authors extend this research by looking at personal and contextual factors together in a single model.acceptedVersio
