Intimate Partner Violence in Urban, Rural, and Remote Areas: An Investigation of Offense Severity and Risk Factors
This study compared the severity of intimate partner violence (IPV) and the relationship between risk factors for IPV and overall risk judgements of future IPV in urban, rural and remote areas. IPV risk assessments conducted by the Swedish police between 2010 and 2014 in urban (n = 564), rural (n = 456), and remote (n = 196) areas were examined. Rurality was associated with the severity of IPV reported, as well as the presence of risk factors and their relationship to overall risk judgements. Cases in remote areas included more severe IPV as well as more risk factors
Neutrino-induced deuteron disintegration experiment
Cross sections for the disintegration of the deuteron via neutral-current
(NCD) and charged-current (CCD) interactions with reactor antineutrinos are
measured to be 6.08 +/- 0.77 x 10^(-45) cm-sq and 9.83 +/- 2.04 x 10^(-45)
cm-sq per neutrino, respectively, in excellent agreement with current
calculations. Since the experimental NCD value depends upon the CCD value, if
we use the theoretical value for the CCD reaction, we obtain the improved value
of 5.98 +/- 0.54 x 10^(-45) for the NCD cross section. The neutral-current
reaction allows a unique measurement of the isovector-axial vector coupling
constant in the hadronic weak interaction (beta). In the standard model, this
constant is predicted to be exactly 1, independent of the Weinberg angle. We
measure a value of beta^2 = 1.01 +/- 0.16. Using the above improved value for
the NCD cross section, beta^2 becomes 0.99 +/- 0.10.Comment: 22pages, 9 figure
Costs of sea dikes – regressions and uncertainty estimates
Failure to consider the costs of adaptation strategies can be seen
by decision makers as a barrier to implementing coastal protection measures.
In order to validate adaptation strategies to sea-level rise in the form of
coastal protection, a consistent and repeatable assessment of the costs is
necessary. This paper significantly extends current knowledge on cost
estimates by developing – and implementing using real coastal dike data –
probabilistic functions of dike costs. Data from Canada and the Netherlands
are analysed and related to published studies from the US, UK, and Vietnam in
order to provide a reproducible estimate of typical sea dike costs and their
uncertainty. We plot the costs divided by dike length as a function of height
and test four different regression models. Our analysis shows that a linear
function without intercept is sufficient to model the costs, i.e. fixed
costs and higher-order contributions such as that due to the volume of core
fill material are less significant. We also characterise the spread around
the regression models which represents an uncertainty stemming from factors
beyond dike length and height. Drawing an analogy with project cost overruns,
we employ log-normal distributions and calculate that the range between 3x
and x∕3 contains 95 % of the data, where x represents the corresponding
regression value. We compare our estimates with previously published unit
costs for other countries. We note that the unit costs depend not only on the
country and land use (urban/non-urban) of the sites where the dikes are being
constructed but also on characteristics included in the costs, e.g. property
acquisition, utility relocation, and project management. This paper gives
decision makers an order of magnitude on the protection costs, which can help
to remove potential barriers to developing adaptation strategies. Although
the focus of this research is sea dikes, our approach is applicable and
transferable to other adaptation measures
Gut barrier-microbiota imbalances in early life lead to higher sensitivity to inflammation in a murine model of C-section delivery
Background Most interactions between the host and its microbiota occur at the gut barrier, and primary colonizers
are essential in the gut barrier maturation in the early life. The mother–ofspring transmission of microorganisms is
the most important factor infuencing microbial colonization in mammals, and C‑section delivery (CSD) is an impor‑
tant disruptive factor of this transfer. Recently, the deregulation of symbiotic host‑microbe interactions in early life
has been shown to alter the maturation of the immune system, predisposing the host to gut barrier dysfunction and
infammation. The main goal of this study is to decipher the role of the early‑life gut microbiota‑barrier alterations and
its links with later‑life risks of intestinal infammation in a murine model of CSD.
Results The higher sensitivity to chemically induced infammation in CSD mice is related to excessive exposure to a
too diverse microbiota too early in life. This early microbial stimulus has short‑term consequences on the host homeo‑
stasis. It switches the pup’s immune response to an infammatory context and alters the epithelium structure and
the mucus‑producing cells, disrupting gut homeostasis. This presence of a too diverse microbiota in the very early
life involves a disproportionate short‑chain fatty acids ratio and an excessive antigen exposure across the vulnerable
gut barrier in the frst days of life, before the gut closure. Besides, as shown by microbiota transfer experiments, the
microbiota is causal in the high sensitivity of CSD mice to chemical‑induced colitis and in most of the phenotypical
parameters found altered in early life. Finally, supplementation with lactobacilli, the main bacterial group impacted by
CSD in mice, reverts the higher sensitivity to infammation in ex‑germ‑free mice colonized by CSD pups’ microbiota.
Conclusions Early‑life gut microbiota‑host crosstalk alterations related to CSD could be the linchpin behind the phe‑
notypic efects that lead to increased susceptibility to an induced infammation later in life in mice.

Abnormal cortical responses to somatosensory stimulation in medication-overuse headache
BACKGROUND: Medication-overuse headache (MOH) is a frequent, disabling disorder. Despite a controversial pathophysiology convincing evidence attributes a pivotal role to central sensitization. Most patients with MOH initially have episodic migraine without aura (MOA) characterized interictally by an absent amplitude decrease in cortical evoked potentials to repetitive stimuli (habituation deficit), despite a normal initial amplitude (lack of sensitization). Whether central sensitization alters this electrophysiological profile is unknown. We therefore sought differences in somatosensory evoked potential (SEP) sensitization and habituation in patients with MOH and episodic MOA. METHODS: We recorded median-nerve SEPs (3 blocks of 100 sweeps) in 29 patients with MOH, 64 with MOA and 42 controls. Episodic migraineurs were studied during and between attacks. We measured N20-P25 amplitudes from 3 blocks of 100 sweeps, and assessed sensitization from block 1 amplitude, and habituation from amplitude changes between the 3 sequential blocks. RESULTS: In episodic migraineurs, interictal SEP amplitudes were normal in block 1, but thereafter failed to habituate. Ictal SEP amplitudes increased in block 1, then habituated normally. Patients with MOH had larger-amplitude block 1 SEPs than controls, and also lacked SEP habituation. SEP amplitudes were smaller in triptan overusers than in patients overusing nonsteroidal anti-inflammatory drugs (NSAIDs) or both medications combined, lowest in patients with the longest migraine history, and highest in those with the longest-lasting headache chronification. CONCLUSIONS: In patients with MOH, especially those overusing NSAIDs, the somatosensory cortex becomes increasingly sensitized. Sensory sensitization might add to the behavioral sensitization that favors compulsive drug intake, and may reflect drug-induced changes in central serotoninergic transmission
