The Making of the Early Modern British Fairy Tradition
ABSTRACTThis review is intended to examine the development of representations of elves and fairies in British culture between the twelfth and the seventeenth centuries. It will argue that a very clear two-stage evolution in those representations can be found in literary sources, from an inchoate range found in different kinds of text, with no apparent collective identity, to a coherent sense of a kingdom, to which the common word ‘fairy’ could be applied, to an intense interest in, and discussion of, the nature of fairies. The first development occurred in the late middle ages, and the second after the Reformation, and both were pan-British phenomena. These literary changes were, moreover, paralleled at each stage, and perhaps responsible for, changes in perception in culture at large. The alterations in representations of these non-human beings, with no clear status in Christian theology, may have wider implications for an understanding of late medieval and early modern cultural history.</jats:p
Modelling treatment, age- and gender-specific recovery in acute injury studies
Background: Acute injury studies often measure physical ability repeatedly over
time through scores that have a finite range. This can result in a faster score change
at the beginning of the study than towards the end, motivating the investigation of
the rate of change. Additionally, the bounds of the score and their dependence on
covariates are often of interest.
Methods: We argue that transforming bounded data is not satisfactory in some
settings. Motivated by the Collaborative Ankle Support Trial (CAST), which investigated
different methods of immobilisation for severe ankle sprains, we developed a
model under the assumption that the recovery rate at a specific time is proportional to
the current score and the remaining score. This model enables a direct interpretation
of the covariate effects. We have re-analyzed the CAST data using these improved
methods, and explored novel relationships between age, gender and recovery rate.
Results: We confirm that using below knee cast is advantageous compared with a
tubular bandage in relation with the recovery rate. An age and gender effect on the
recovery rate and the maximum achievable score is demonstrated, with older female
patients recovering less fast (age-effect: -0.21, 95% confidence interval (CI) [-0.28,-
0.14]; gender effect: -0.06, CI [-0.12,-0.004]) and achieving a lower maximum score
(age-effect: -8.07, CI [-11.68,-4.01]; gender-effect: -5.34, CI [-8.18, -2.50]) than younger
male patients.
Conclusions: Our model is able to accurately model repeated measurements on the
original scale, while accounting for the bounded nature of a score. We demonstrate
that recovery in acute injury trials can differ substantially by age and gender. Older
female patients are less likely to recover well from a sprain
Aftershocks and Preearthquake Seismicity
Although primary surface faulting was mapped for nearly 30 km,
aftershocks extended in a complex pattern more than 100 km along
the trend of the Imperial fault. A first-motion focal mechanism for the
main shock is consistent with right-lateral motion on a vertical fault
striking N. 42° W., in agreement with the strike of the Imperial fault
within the limits of resolution. There is evidence that conjugate faulting
on a buried complementary northeast-trending structure occurred
at the north limit of displacement on the Imperial fault near Brawley,
Calif. This faulting was apparently initiated at the time of a magnitude
5.8 aftershock 8 hours after the main shock. A line of epicenters
extending along the trend of the San Andreas fault nearly 100 km into
the eastern Imperial Valley was noted during the aftershock sequence,
in an area recognized as notably aseismic during the preceding
5 years. The main shock was preceded by a 3-month period of
significantly reduced seismicity affecting the central Imperial Valley.
Although three small events near the incipient epicenter during this
interval may be deemed foreshocks, no distinct foreshocks immediately
before the main shock were observed
On the calibration of the relation between geometric albedo and polarimetric properties for the asteroids
We present a new extensive analysis of the old problem of finding a
satisfactory calibration of the relation between the geometric albedo and some
measurable polarization properties of the asteroids. To achieve our goals, we
use all polarimetric data at our disposal. For the purposes of calibration, we
use a limited sample of objects for which we can be confident to know the
albedo with good accuracy, according to previous investigations of other
authors. We find a new set of updated calibration coefficients for the
classical slope - albedo relation, but we generalize our analysis and we
consider also alternative possibilities, including the use of other
polarimetric parameters, one being proposed here for the first time, and the
possibility to exclude from best-fit analyzes the asteroids having low albedos.
We also consider a possible parabolic fit of the whole set of data.Comment: Accepted by MNRA

Enhancing Missouri Traffic Safety with a Primary Enforcement Seat Belt Law
In 1984, New York became the first state to enact a mandatory seat belt law; since then, the District of Columbia and every state except New Hampshire have adopted similar laws. Of the 49 states with seat belt laws, eight states originally included primary enforcement provisions in seat belt laws, which allow police to stop a driver solely on the basis of not wearing a seat belt. In
1993, California upgraded their secondary seatbelt enforcement provision to a primary law. Since then, 12 more states and the District of Columbia have strengthened their belt laws by making them primary enforcement
laws. Missouri continues to permit only secondary enforcement and allows a minimal 4.7 billion in 2000. A 2004 study commissioned by the National Safety Council shows Missouri could save at least $103 million dollars over the next ten years in Medicaid costs once a primary enforcement seat belt law was adopted
Identifying studies for systematic reviews - An example from medical imaging
Objectives: To determine if published figures on the proportion of articles included in systematic reviews and identified in electronic databases are applicable to an example from medical imaging.
Methods: A systematic review was performed. Additionally, sensitivity and precision of a MEDLINE search were compared with values from three published searches, each customized for a specific field.
Results: All articles included in the systematic review were in electronic databases. The MEDLINE search had low precision compared with searches in other fields.
Conclusions: in a specific area of medical imaging, electronic databases, including MEDLINE, are reliable sources of articles

A family resemblance? The regulation of marriage migration in Europe
This article analyses key aspects of the regulation of entry and stay of spousal migrants in EEA member states. It shows that there are differences of regulation, particularly between states in Eastern and Southern Europe and states in Northern and Western Europe but, in most cases, the amount of divergence is limited. The article connects this ‘family resemblance’ to a broad concept of Europeanisation. Even where there is no binding legal obligation, European legal norms and the practice in other European states largely circumscribe what is possible
Reply to “Comment on ‘Revisiting the 1872 Owens Valley, California, Earthquake’ by Susan E. Hough and Kate Hutton” by William H. Bakun
Bakun (2009) argues that the conclusions of Hough and Hutton (2008) are wrong because the study failed to take into account the Sierra Nevada attenuation model of Bakun (2006). In particular, Bakun (2009) argues that propagation effects can explain the relatively high intensities generated by the 1872 Owens Valley earthquake. Using an intensity attenuation model that attempts to account for attenuation through the Sierra Nevada, Bakun (2006) infers the magnitude estimate (M_w 7.4–7.5) that is currently accepted by National Earthquake Information Center (NEIC)
