One size does not fit all: Tailoring Peer Support Programmes for optimal student engagement
Authors: Davies Rosey , Pocklington Amanda , Allington Simon 
Published: September 2017

Peer Support Programmes (PSPs) have long been a feature of student engagement activity at the University of Exeter. Peer Support at Exeter started over eight years ago, with just two discipline-specific programmes. Since then, the number of programmes has increased significantly, but throughout this period of growth the bespoke nature of the programmes has been retained. All PSPs are student-led and, crucially, they are tailored to meet the specific needs of the student group involved. We, the authors, are firmly of the opinion that ‘one size does not fit all’ and that tailoring every programme to the specific needs of each student group is vital if it is to be successful. It is now recognised that engagement in interventions such as PSPs can play an important role in improving student retention and success (Thomas, 2012) and that an understanding of ‘local contexts’ can enhance the efficacy of such programmes (Thomas et al, 2017). However, this was not as well understood when PSPs were first introduced at Exeter. This short paper seeks to present an overview of the evolution of PSPs at the University of Exeter, which may provide others with a useful insight into the development of tailored PSPs for optimal student engagement.

Transport Quality Profiles of European Cities Based on a Multidimensional Set of Satisfaction Ratings Indicators
Authors: Diana Marco , Duarte André , Pirra Miriam 
Published: September 2017

A monitoring system of perceived quality of transport services at the city level is proposed on the basis of a set of 92 indicators covering various travel modes and considering the viewpoints of different groups. Special emphasis was given to public transport, bicycles, pedestrians, and travelers with special needs (e.g., commuters, visitors, mobility-challenged or communication-impaired travelers). Indicators were found through principal component analysis from a set of satisfaction ratings elicited through a survey in eight European cities, implemented within the METPEX research project, a measurement tool to determine the quality of passenger experience. Benchmarking values were computed for all indicators to provide the analyst with some initial guidance. All indicators were then visualized through a dashboard that could give policy makers a synthetic overview of the main areas where perceived quality and accessibility were above or below average. At the same time, joint consideration of indicators from different dimensions of the evaluation exercise—by travel means, by traveler profile, by phase of the journey experience—provided additional insights on specific issues that would be overlooked in a coarser-quality assessment activity.
Possible threshold controls on sediment grain properties of Peruvian coastal river basins
Authors: Litty Camille , Schlunegger Fritz , Viveen Willem 
Published: September 2017

Abstract. To determine possible controls on sediment grain properties, 21 coastal rivers located along the entire western Peruvian margin were analysed. This represents one of the largest grain size dataset that has been collected over a large area. Modern gravel beds were sampled along a north–south transect on the western side of the Peruvian Andes where the rivers cross the tip of the mountain range, and at each site the long a axis and the intermediate b axis of about 500 pebbles were measured. Morphometric properties of each drainage basin, sediment and water discharge, together with flow shear stresses, were determined and compared against measured grain properties. Pebble size data show that the values for the D50 are nearly constant and range between 2 and 3 cm, while the values of the D96 range between 6 and 12 cm. The ratios between the intermediate and the long axis range from 0.67 to 0.74. Linear correlations between all grain size percentiles and water shear stresses, mean basin denudation rates, mean basin slopes and basin sizes are small to non-existent. However, exceptionally large D50 values of 4–6 cm were measured for basins situated between 11–12 and 16–17° S latitude where hillslope gradients are steeper than on average or where mean annual stream flows exceed the average values of the western Peruvian streams by a factor of 2. We suggest that the generally uniform grain size pattern has been perturbed where either mean basin slopes or water fluxes exceed threshold conditions.
Optimizing the parameterization of deep mixing and internal seiches in one-dimensional hydrodynamic models: a case study with Simstrat v1.3

Published: September 2017

Abstract. This paper presents an improvement of a one-dimensional lake hydrodynamic model (Simstrat) to characterize the vertical thermal structure of deep lakes. Using physically based arguments, we refine the transfer of wind energy to basin-scale internal waves (BSIWs). We consider the properties of the basin, the characteristics of the wind time series and the stability of the water column to filter and thereby optimize the magnitude of wind energy transferred to BSIWs. We show that this filtering procedure can significantly improve the accuracy of modelled temperatures, especially in the deep water of lakes such as Lake Geneva, for which the root mean square error between observed and simulated temperatures was reduced by up to 40 %. The modification, tested on four different lakes, increases model accuracy and contributes to a significantly better reproduction of seasonal deep convective mixing, a fundamental parameter for biogeochemical processes such as oxygen depletion. It also improves modelling over long time series for the purpose of climate change studies.
Rivaroxaban Causes Missed Diagnosis of Protein S Deficiency but Not of Activated Protein C Resistance (Factor V Leiden)
Authors: Maryamchik Elena , Rosenbaum Matthew W. , Van Cott Elizabeth M. 
Published: September 2017

Context.—
Rivaroxaban causes a false increase in activated protein C resistance (APCR) ratios and protein S activity.

Objective.—
To investigate whether this increase masks a diagnosis of factor V Leiden (FVL) or protein S deficiency in a “real-world” population of patients undergoing rivaroxaban treatment and hypercoagulation testing.

Design.—
During a 2.5-year period, we compared 4 groups of patients (n = 60): FVL heterozygous (FVL-HET)/taking rivaroxaban, wild-type/taking rivaroxaban, FVL-HET/no rivaroxaban, and normal APCR/no rivaroxaban. Patients taking rivaroxaban were tested for protein S functional activity and free antigen (n = 32).

Results.—
The FVL-HET patients taking rivaroxaban had lower APCR ratios than wild-type patients (P &lt; .001). For FVL-HET patients taking rivaroxaban, mean APCR was 1.75 ± 0.12, versus 1.64 ± 0.3 in FVL-HET patients not taking rivaroxaban (P = .005). Activated protein C resistance in FVL-HET patients fell more than 3 SDs below the cutoff of 2.2 at which the laboratory reflexes FVL DNA testing. No cases of FVL were missed despite rivaroxaban. In contrast, rivaroxaban falsely elevated functional protein S activity, regardless of the presence or absence of FVL (P &lt; .001). A total of 4 of 32 patients (12.5%) had low free protein S antigen (range, 58%–67%), whereas their functional protein S activity appeared normal (range 75%–130%). Rivaroxaban would have caused a missed diagnosis of all cases of protein S deficiency during the study if testing relied on the protein S activity assay alone.

Conclusions.—
Despite rivaroxaban treatment, APCR testing can distinguish FVL-HET from normal patients, rendering indiscriminate FVL DNA testing of all patients on rivaroxaban unnecessary. Free protein S should be tested in patients taking rivaroxaban to exclude hereditary protein S deficiency.
Integrative taxonomy of the ornamental ‘peppermint’ shrimp public market and population genetics ofLysmata boggessi, the most heavily traded species worldwide
Authors: Baeza J. Antonio , Behringer Donald C. 
Published: September 2017

The ornamental trade is a worldwide industry worth >15 billion USD with a problem of rampant product misidentification. Minimizing misidentification is critical in the face of overexploitation of species in the trade. We surveyed the peppermint shrimp ornamental marketplace in the southeastern USA, the most intense market for peppermint shrimps worldwide, to characterize the composition of species in the trade, reveal the extent of misidentification, and describe the population genetics of the true target species. Shrimps were bought from aquarium shops in FL, GA, SC, and NC. We demonstrated, contrary to popular belief (information from dealers), that the most heavily traded species in the market wasLysmata boggessi, an endemic species to the eastern Gulf of Mexico, and notLysmata wurdemanni. Importantly, only when color pattern or genetic markers in conjunction with morphological traits were employed, was it was possible to unequivocally identifyL. boggessias the only species in the trade. The intensity of the market for peppermint shrimps in the USA has led toL. boggessibeing the most traded species worldwide. Misidentification in the shrimp aquarium trade is accidental and involuntary, and is explained by remarkable similarity among congeneric species. Using sequences of the 16S-mt-DNA marker, we found no indication of population genetic structure in the endemicL. boggessiacross 550 km of linear coast. Therefore, this species can be considered genetically homogeneous and a single fished stock. Still, we argue in favor of additional studies using more powerful markers (e.g., SNPs) capable of revealing genetic structure at a finer spatial-scale. Our results will help advance management and conservation policies in this lucrative yet understudied fishery. Future studies of other ornamental fisheries will benefit from using an integrative taxonomic approach, as we demonstrate here.
Sylvatic host associations of Triatominae and implications for Chagas disease reservoirs: a review and new host records based on archival specimens
Authors: Georgieva Anna Y. , Gordon Eric R.L. , Weirauch Christiane 
Published: September 2017

BackgroundThe 152 extant species of kissing bug include important vectors of the debilitating, chronic, and often fatal Chagas disease, which affects several million people mainly in Central and South America. An understanding of the natural hosts of this speciose group of blood-feeding insects has and will continue to aid ongoing efforts to impede the spread of Chagas disease. However, information on kissing bug biology is piecemeal and scattered, developed using methods with varying levels of accuracy over more than 100 years. Existing host records are heavily biased towards well-studied primary vector species and are derived from primarily three different types of observations, associational, immunological or DNA-based, with varying reliability.MethodsWe gather a comprehensive and unparalleled number of sources reporting host associations via rigorous targeted searches of publication databases to review all known natural, or sylvatic, host records including information on how each record was collected. We integrate this information with novel host records obtained via attempted amplification and sequencing of a ∼160 base pair (bp) region of the vertebrate 12S mitochondrial gene from the gastrointestinal tract of 64 archival specimens of Triatominae representing 19 species collected primarily in sylvatic habitats throughout the southern United States and Central and South America during the past 10 years. We show the utility of this method for uncovering novel and under-studied groups of Triatominae hosts, as well as detecting the presence of the Chagas disease pathogen via Polymerase Chain Reaction (PCR) of a ∼400 bp sequence of the trypanosome 18S gene.ResultsNew host associations for several groups of arboreal mammals were determined including sloths, New World monkeys, coatis, arboreal porcupines and, for the first time as a host of any Triatominae, tayras. A thorough review of previously documented sylvatic hosts, organized by triatomine species and the type of observation (associational, antibody-based, or DNA-based), is presented in a phylogenetic context and highlights large gaps in our knowledge of Triatominae biology.ConclusionThe application of DNA-based methods of host identification towards additional species of Triatominae, including rarely collected species that may require use of archival specimens, is the most efficient and promising way to resolve recognized shortfalls.
Stress‐ and Structure‐Induced Anisotropy in Southern California From Two Decades of Shear Wave Splitting Measurements
Authors: Li Zefeng , Peng Zhigang 
Published: September 2017

AbstractWe measure shear wave splitting (SWS) parameters (i.e., fast direction and delay time) using 330,000 local earthquakes recorded by more than 400 stations of the Southern California Seismic Network (1995–2014). The resulting 232,000 SWS measurements (90,000 high‐quality ones) provide a uniform and comprehensive database of local SWS measurements in Southern California. The fast directions at many stations are consistent with regional maximum compressional stress σHmax. However, several regions show clear deviations from the σHmax directions. These include linear sections along the San Andreas Fault and the Santa Ynez Fault, geological blocks NW to the Los Angeles Basin, regions around the San Jacinto Fault, the Peninsular Ranges near San Diego, and the Coso volcanic field. These complex patterns show that regional stresses and active faults cannot adequately explain the upper crustal anisotropy in Southern California. Other types of local structures, such as local rock types or tectonic features, also play significant roles.
Pareto‐Optimal Estimates of California Precipitation Change
Authors: Langenbrunner Baird , Neelin J. David 
Published: September 2017

AbstractIn seeking constraints on global climate model projections under global warming, one commonly finds that different subsets of models perform well under different objective functions, and these trade‐offs are difficult to weigh. Here a multiobjective approach is applied to a large set of subensembles generated from the Climate Model Intercomparison Project phase 5 ensemble. We use observations and reanalyses to constrain tropical Pacific sea surface temperatures, upper level zonal winds in the midlatitude Pacific, and California precipitation. An evolutionary algorithm identifies the set of Pareto‐optimal subensembles across these three measures, and these subensembles are used to constrain end‐of‐century California wet season precipitation change. This methodology narrows the range of projections throughout California, increasing confidence in estimates of positive mean precipitation change. Finally, we show how this technique complements and generalizes emergent constraint approaches for restricting uncertainty in end‐of‐century projections within multimodel ensembles using multiple criteria for observational constraints.

AbstractThe probability distribution of turbulent kinetic energy dissipation rate in stratified ocean usually deviates from the classic lognormal distribution that has been formulated for and often observed in unstratified homogeneous layers of atmospheric and oceanic turbulence. Our measurements of vertical profiles of micro‐scale shear, collected in the East China Sea, northern Bay of Bengal, to the south and east of Sri Lanka, and in the Gulf Stream region, show that the probability distributions of the dissipation rate
in the pycnoclines (r ∼ 1.4 m is the averaging scale) can be successfully modeled by the Burr (type XII) probability distribution. In weakly stratified boundary layers, lognormal distribution of
is preferable, although the Burr is an acceptable alternative. The skewness
and the kurtosis
of the dissipation rate appear to be well correlated in a wide range of
and
variability.
Impacts of Recent Warming and the 2015/2016 El Niño on Tropical Peruvian Ice Fields

AbstractData collected between 1974 and 2016 from snow pits and core samples from two Peruvian ice fields demonstrate the effect of the recent warming over the tropical Andes, augmented by El Niño, on the preservation of the climate record. As the 0°C isotherm is approaching the summit of the Quelccaya ice cap in the Andes of southern Peru (5,670 meters above sea level (masl)), the distinctive seasonal δ18O oscillations in the fresh snow deposited within each thermal year are attenuated at depth due to melting and percolation through the firn. This has become increasingly pronounced over 43 years. In the Andes of northern Peru, the ice field on the col of Nevado Huascarán (6050 masl) has retained its seasonal δ18O variations at depth due to its higher elevation. During the 2015/2016 El Niño, snow on Quelccaya and Huascarán was isotopically (δ18O) enriched and the net sum of accumulation over the previous year (NSA) was below the mean for non–El Niño years, particularly on Quelccaya (up to 64% below the mean) which was more pronounced than the NSA decrease during the comparable 1982/1983 El Niño. Interannual large‐scale oceanic and middle to upper‐level atmospheric temperatures influence δ18O in precipitation on both ice fields, although the influences are variably affected by strong El Niño–Southern Oscillation events, especially on Quelccaya. The rate of ice wastage along Quelccaya's margin was dramatically higher during 2015/2016 compared with that of the previous 15 years, suggesting that warming from future El Niños may accelerate mass loss on Peruvian glaciers.
