The personal development planning cycle.
This Learning and CPD sheet is designed to pull together into a framework many of the activities that have already been published. It should also help anyone planning to go for audit of their CPD or who have been requested to submit for audit. There are a number of different ways of viewing the Personal Development Planning (PDP) or CPD cycle; the one covered here is just one example and shouldn't be seen as the only way of looking at PDP. For a greater range of activities, look at the book "Skills for Success: The Personal Development Planning Handbook" by Cottrell and the companion website
Operating theatre photography for orthopaedics and aesthetic surgery.
The aim of this paper is to examine the author's personal experience and practice in operating theatre photography. The ways of working are personal to the author but hopefully will help others in undertaking this type of work
Are you a researcher as well as a medical illustrator?
When we list the areas of practice for medical illustrators we always include research, but how involved in research are we? The aim of this activity is to encourage your professional development not just as a medical illustrator but your involvement with research whether that is undertaking your own research, undertaking evidence based practice (1) , working as part of a research team, advising researchers on the value of medical illustration or supporting a student undertaking a research project for their degree or post-graduate qualification
Nonlinear asteroseismology of RR Lyrae
The observations of the Kepler space telescope revealed that fundamental-mode
RR Lyrae stars may show various radial overtones. The presence of multiple
radial modes may allow us to conduct nonlinear asteroseismology: comparison of
mode amplitudes and frequency shifts between observations and models. Here we
report the detection of three radial modes in the star RR Lyr, the eponym of
the class, using the Kepler short cadence data: besides the fundamental mode,
both the first and the ninth overtones can be derived from the data set. RR
Lyrae shows period doubling, but switches occasionally to a state where a
pattern of six pulsation cycles repeats instead of two. We found hydrodynamic
models that show the same three modes and the period-six state, allowing for
comparison with the observations.Comment: 5 pages, 4 figures, accepted for publication in ApJ Letter
Mouse tafazzin is required for male germ cell meiosis and spermatogenesis
Barth syndrome is an X-linked mitochondrial disease, symptoms of which include neutropenia and cardiac myopathy. These symptoms are the most significant clinical consequences of a disease, which is increasingly recognised to have a variable presentation. Mutation in the Taz gene in Xq28 is thought to be responsible for the condition, by altering mitochondrial lipid content and mitochondrial function. Male chimeras carrying a targeted mutation of Taz on their X-chromosome were infertile. Testes from the Taz knockout chimeras were smaller than their control counterparts and this was associated with a disruption of the progression of spermatocytes through meiosis to spermiogenesis. Taz knockout ES cells also showed a defect when differentiated to germ cells in vitro. Mutant spermatocytes failed to progress past the pachytene stage of meiosis and had higher levels of DNA double strand damage and increased levels of endogenous retrotransposon activity. Altogether these data revealed a novel role for Taz in helping to maintain genome integrity in meiosis and facilitating germ cell differentiation. We have unravelled a novel function for the Taz protein, which should contribute to an understanding of how a disruption of the Taz gene results in the complex symptoms underlying Barth Syndrome
Efficiency at optimal work from finite reservoirs: a probabilistic perspective
We revisit the classic thermodynamic problem of maximum work extraction from
two arbitrary sized hot and cold reservoirs, modelled as perfect gases.
Assuming ignorance about the extent to which the process has advanced, which
implies an ignorance about the final temperatures, we quantify the prior
information about the process and assign a prior distribution to the unknown
temperature(s). This requires that we also take into account the temperature
values which are regarded to be unphysical in the standard theory, as they lead
to a contradiction with the physical laws. Instead in our formulation, such
values appear to be consistent with the given prior information and hence are
included in the inference. We derive estimates of the efficiency at optimal
work from the expected values of the final temperatures, and show that these
values match with the exact expressions in the limit when any one of the
reservoirs is very large compared to the other. For other relative sizes of the
reservoirs, we suggest a weighting procedure over the estimates from two valid
inference procedures, that generalizes the procedure suggested earlier in [J.
Phys. A: Math. Theor. {\bf 46}, 365002 (2013)]. Thus a mean estimate for
efficiency is obtained which agrees with the optimal performance to a high
accuracy.Comment: 14 pages, 6 figure
Environmental and genetic influences on neurocognitive development: the importance of multiple methodologies and time-dependent intervention
Genetic mutations and environmental factors dynamically influence gene expression and developmental trajectories at the neural, cognitive, and behavioral levels. The examples in this article cover different periods of neurocognitive development—early childhood, adolescence, and adulthood—and focus on studies in which researchers have used a variety of methodologies to illustrate the early effects of socioeconomic status and stress on brain function, as well as how allelic differences explain why some individuals respond to intervention and others do not. These studies highlight how similar behaviors can be driven by different underlying neural processes and show how a neurocomputational model of early development can account for neurodevelopmental syndromes, such as autism spectrum disorders, with novel implications for intervention. Finally, these studies illustrate the importance of the timing of environmental and genetic factors on development, consistent with our view that phenotypes are emergent, not predetermined
Teenage Conduct Problems: A Lifetime of Disadvantage in the Labour Market?
Using data from two British birth cohorts born in 1958 and 1970 we investigate the impact of teenage conduct problems on subsequent employment prospects through to age 42. We find teenagers with conduct problems went on to spend fewer months both in paid employment, and in employment, education and training (EET) between age 17 and 42 than comparable teenagers who did not experience conduct problems. Employment and EET disadvantages were greatest among those with severe behavioural problems. The ‘gap’ in time spent in employment or EET by conduct problem status was similar for men and women across cohorts, with only a small part of the gap being attenuated by differences in social background, individual characteristics and educational attainment in public examination at age 16. We discuss the implications of our findings
Health IT Security: An Examination of Modern Challenges in Maintaining HIPAA and HITECH Compliance
This work describes an undergraduate honors research project into some of the challenges modern healthcare providers face in maintaining compliance with the Health Insurance Portability and Accountability Act (HIPAA) and HITECH (Health Information Technology for Economic and Clinical Health) Act. An overview of the pertinent sections of both the HIPAA and HITECH Acts regarding health information security is provided, along with a discussion of traditionally weak points in information security, including: people susceptible to social engineering, software that is not or cannot be regularly updated, and targeted attacks (including advanced persistent threats, or APTs). Further, the paper examines potential violations of HIPAA involving vulnerabilities in commonly-used enterprise health records systems. Finally, we compare these challenges to the challenges of the United States healthcare system prior to 1995, specifically looking at information handling procedures, how procedures have changed, and how effective those changes have been
