    In human cervical neoplasia human papillomavirus (HPV) type 18 has a higher cancer/cervical intraepithelial neoplasia (CIN) prevalence ratio than HPV 16. Fibrosarcomas derived from rat fibroblasts transfected with HPV 16 or 18 genomes showed increased apoptosis compared with controls. However, HPV 18 was associated with significantly less apoptosis than HPV 16, affording one possible explanation for the more rapidly progressive cervical neoplasia associated with HPV 18

    Acknowleding attributes that enable the career academic nurse to thrive in the tertiary education sector: A qualitative systematic review

    © 2016 Objective To optimise the career development in early career academic nurses by providing an overview of the attributes necessary for success. Background Evidence of early prospective career planning is necessary to optimise success in the tertiary sector. This is particularly important for nurse academics given the profession's later entry into academia, the ageing nursing workforce and the continuing global shortage of nurses. Design A qualitative systematic review. Methods Academic Search Complete, CINAHL, Medline, ERIC, Professional Development Collection and Google Scholar databases were searched; resulting in the inclusion of nine qualitative nurse-only focussed studies published between 2004 and 2014. The studies were critically appraised and the data thematically analysed. Results Three abilities were identified as important to the early career academic nurse: a willingness to adapt to change, an intention to pursue support and embodying resilience. These abilities give rise to attributes that are recommended as key to successful academic career development for those employed on a continuing academic basis. Conclusions The capacity to rely on one's own capabilities is becoming seen as increasingly important. It is proposed that recognition of these attributes, their skilful application and monitoring outlined in the review are recommended for a successful career in academia

    Magic wavelengths for the 5s−18s5s-18s transition in rubidium

    Magic wavelengths, for which there is no differential ac Stark shift for the ground and excited state of the atom, allow trapping of excited Rydberg atoms without broadening the optical transition. This is an important tool for implementing quantum gates and other quantum information protocols with Rydberg atoms, and reliable theoretical methods to find such magic wavelengths are thus extremely useful. We use a high-precision all-order method to calculate magic wavelengths for the 5s−18s5s-18s transition of rubidium, and compare the calculation to experiment by measuring the light shift for atoms held in an optical dipole trap at a range of wavelengths near a calculated magic value

    The Pilgrim’s Progress: early-career academic nurses’ journey of shaping, strengthening and sustaining a career mindset

    University of Technology Sydney. Faculty of Health.There is an emerging body of literature on the experiences of early career academic nurses with a particular focus on their learning needs and how they can best be supported as they compete for success in a highly competitive and rapidly changing environment. Managing an academic career can be challenging and there is a need to fully understand the attitudes, abilities and habits that contribute to a successful career mindset. This knowledge will benefit both early career academics and higher education providers wishing to implement supportive interventions aimed at capacity building and retention. The aim of the study was to explore their experiences of shaping, strengthening and sustaining career growth. A systematic literature review followed by a four phase-study was undertaken. Phase one explored the early career academic nurses’ initial career journey. In phase two a supportive educational intervention was trialled and critically evaluated. Phase three consisted of collective narratives that identified key elements of participants’ growth mindset’ and how it intersected with their career success; and Phase four was added using a narrative-based approach to represent the early career academic nurses’ progress. A qualitative descriptive design was used with data thematically analysed using the six-phase approach of Braun and Clarke (2012). This thesis is presented as a compilation of chapters and publications. Early career academic nurses spend a great deal of time and energy aiming to construct a successful career. A supportive educational program that facilitated the development of attributes that support a growth mindset was found to engender success and generate opportunities for career progress. A ‘growth mindset’ was viewed as the best way to understand and enhance personal abilities that assist with strengthening and sustaining the academic journey. The early career academic nurses in this study viewed support as a range of factors and learning opportunities that allowed them to shape and strengthen their individual career path. This study adds to the literature about early career academic nurse’s long-term experiences in undertaking an academic career. It identified that building a successful academic career demands input from both the individuals and senior leadership. While the early career academic nurses must seek to develop dispositions to meet demands that accompany an academic career, higher education providers need to implement programs and supportive strategies that enhance the skills and abilities of early career academic nurses to promote their success and retention

    A model for the generic alpha relaxation of viscous liquids

    Get PDF
    Dielectric measurements on molecular liquids just above the glass transition indicate that alpha relaxation is characterized by a generic high-frequency loss varying as ω−1/2\omega^{-1/2}, whereas deviations from this come from one or more low-lying beta processes [Olsen et al, Phys. Rev. Lett. {\bf 86} (2001) 1271]. Assuming that long-wavelength fluctuations dominate the dynamics, a model for the dielectric alpha relaxation based on the simplest coupling between the density and dipole density fields is proposed here. The model, which is solved in second order perturbation theory in the Gaussian approximation, reproduces the generic features of alpha relaxation

    Magnetocardiography with a modular spin-exchange relaxation free atomic magnetometer array

    Full text link
    We present a portable four-channel atomic magnetometer array operating in the spin exchange relaxation-free regime. The magnetometer array has several design features intended to maximize its suitability for biomagnetic measurement, specifically foetal magnetocardiography, such as a compact modular design, and fibre coupled lasers. The modular design allows the independent positioning and orientation of each magnetometer, in principle allowing for non-planar array geometries. Using this array in a magnetically shielded room, we acquire adult magnetocadiograms. These measurements were taken with a 6-11 fT Hz^(-1/2) single-channel baseline sensitivity that is consistent with the independently measured noise level of the magnetically shielded room.Comment: 15 pages, 5 figure
