Published: December 2019

AbstractObjectiveTo analyse how the auditory brainstem response changes in patients with sudden sensorineural hearing loss.MethodData were collected via retrospective medical chart review.ResultsForty-three patients were included in this study. The mean latency of auditory brainstem response wave 1 was significantly longer for the affected side than for the unaffected side (p = 0.003). The mean latency of auditory brainstem response wave 1 was significantly shorter, and the mean amplitude of auditory brainstem response wave 1 was significantly larger, in the good response group compared to the poor response group. In forward conditional logistic regression analysis, auditory brainstem response wave 1 latency was an independent predictor of a good response (odds ratio = 34.37, 95 per cent confidence interval = 1.56–757.15, p = 0.025).ConclusionIn patients with sudden sensorineural hearing loss, the latency of wave 1 of the auditory brainstem response was significantly increased and was related to prognosis.
Writing for redress: redrawing the epistolary relationship under the New Poor Law
Authors: Jones Peter D. , Carter Natalie 
Published: December 2019

AbstractThis article investigates how the new welfare bureaucracy impacted on the epistolary relationship between paupers and those who administered it locally and nationally. In particular, it traces the changes in those relationships between the earliest years of the new regime and its maturity in the 1870s. It explores the ways that paupers responded to the New Poor Law, and how they negotiated the structural and sentimental shifts that took place over that period. In particular, it looks in detail at the new uses to which the epistolary relationship was put by outdoor paupers, their advocates and workhouse inmates.
Imitation of human motion for humanoid robot in lift and carry event
Authors: Chiang Shu-Yin , Jiang Hao-Ge 
Published: December 2019

Abstract
This study proposed a method to enable a humanoid robot to step up onto a stair by imitating the step-up motion of a human and to accomplish a lift and carry event in HuroCup of Federation of International RoboSports Association. The step-up motion, divided into five states, was captured by a Kinect sensor, and the human joints corresponded to the humanoid robot joints. Selected servomotors and their angle variation were matched with that of human joint numbers by a designed fuzzy inference system on the basis between the human and the humanoid robot joints. Then, the rest of the robot motors were adjusted by the zero moment point obtained from force-sensing registers to maintain stability. Next, two intermediate transition states were added between each state of the humanoid robot step-up to maintain its balance and reduce motor damage. Finally, to be applied in a real lift and carry event, a vision system was integrated to recognize the edge of a color board and determine a suitable site for the step-up. With these functions integrated, the robot under the proposed method was verified to successfully achieve the task of the lift and carry event without losing its balance or falling.
Story choice matters for caregiver extra-textual talk during shared reading with preschoolers

Published: December 2019

AbstractThis study aimed to examine the influence of the complexity of the story-book on caregiver extra-textual talk (i.e., interactions beyond text reading) during shared reading with preschool-age children. Fifty-three mother–child dyads (3;00–4;11) were video-recorded sharing two ostensibly similar picture-books: a simple story (containing no false belief) and a complex story (containing a false belief central to the plot, which provided content that was more challenging for preschoolers to understand). Book-reading interactions were transcribed and coded. Results showed that the complex stories facilitated more extra-textual talk from mothers, and a higher quality of extra-textual talk (as indexed by linguistic richness and level of abstraction). Although the type of story did not affect the number of questions mothers posed, more elaborative follow-ups on children's responses were provided by mothers when sharing complex stories. Complex stories may facilitate more and linguistically richer caregiver extra-textual talk, having implications for preschoolers’ developing language abilities.
Functions and mechanism of noncoding RNA in the somatic cells of the testis
Authors: Li Chunjie , Chen Baiqi , Wang Jing 
Published: December 2019

SummaryncRNAs are involved in numerous biological processes by regulating gene expression and cell stability. Studies have shown that ncRNAs also contribute to spermatogenesis. Leydig cells (LCs) and Sertoli cells (SCs) are somatic cells of the testis that support spermatogenesis and are vital to male fertility. In this review, we summarized the findings from studies on ncRNAs in SCs and LCs. In SCs, ncRNAs play key roles in phagocytosis, immunoprotection and development of SCs. In LCs, ncRNAs are involved in steroidogenesis, in particular production of testosterone as well as development of LCs. Here, we discuss the possible target genes and functions of ncRNAs in both types of cells. These ncRNAs regulate the expression of target genes or mRNA coding sequence regions, resulting in a chain reaction that influences cell function. In addition, microRNAs, lncRNAs, piRNA-like RNAs (pilRNAs) and natural antisense transcripts (NATs) are discussed in this review. In summary, we suggest that these ncRNAs might act in coordination to control spermatogenesis and maintain the environmental homeostasis of the testis.

Published: December 2019

AbstractTroponin levels are often obtained when chest pain is evaluated in the paediatric emergency department. Elevations in troponin levels can be due to different causes, and it is important to fully understand all of these possible causes to help streamline further evaluation and therapy. We present the case of a teenager who had two episodes of troponin elevation in the setting of rhabdomyolysis.

AbstractObjective:American Indians experience substantial health disparities relative to the US population, including vascular brain aging. Poorer cognitive test performance has been associated with cranial magnetic resonance imaging findings in aging community populations, but no study has investigated these associations in elderly American Indians.Methods:We examined 786 American Indians aged 64 years and older from the Cerebrovascular Disease and its Consequences in American Indians study (2010–2013). Cranial magnetic resonance images were scored for cortical and subcortical infarcts, hemorrhages, severity of white matter disease, sulcal widening, ventricle enlargement, and volumetric estimates for white matter hyperintensities (WMHs), hippocampus, and brain. Participants completed demographic, medical history, and neuropsychological assessments including testing for general cognitive functioning, verbal learning and memory, processing speed, phonemic fluency, and executive function.Results:Processing speed was independently associated with the presence of any infarcts, white matter disease, and hippocampal and brain volumes, independent of socioeconomic, language, education, and clinical factors. Other significant associations included general cognitive functioning with hippocampal volume. Nonsignificant, marginal associations included general cognition with WMH and brain volume; verbal memory with hippocampal volume; verbal fluency and executive function with brain volume; and processing speed with ventricle enlargement.Conclusions:Brain-cognition associations found in this study of elderly American Indians are similar to those found in other racial/ethnic populations, with processing speed comprising an especially strong correlate of cerebrovascular disease. These findings may assist future efforts to define opportunities for disease prevention, to conduct research on diagnostic and normative standards, and to guide clinical evaluation of this underserved and overburdened population.
Is the Sri Lankan ecotourism industry threatened by climate change? A case study of Rekawa coastal wetland using contingent visitation approach
Authors: Salpage Nesha Dushani , Aanesen Margrethe , Amarasinghe Oscar 
Published: December 2019

AbstractThis study investigates intended visitation behavior of tourists toward Rekawa wetland under anticipated climate change (CC) scenarios. An interview-based contingent visitation survey was conducted with 365 foreign and domestic tourists to estimate the effects of CC on future visitation. Based on two IPCC scenarios using two direct and three indirect climatic factors, we composed a CC environmental index. The results show a decline in number of trips equal to 43 per cent and 53 per cent under scenarios 1 and 2 respectively, but the difference is not significant. Foreign and domestic tourists differ significantly with regard to socio-demographic characteristics and beliefs about CC effects at Rekawa. Controlling for such differences, we demonstrate that foreign tourists are less likely than domestic tourists to reduce future visitation to Rekawa due to CC impacts. Still, the future of ecotourism at Rekawa wetland is at risk if adaptation measures are not taken to meet CC impacts.
Food safety considerations in integrated organic crop–livestock systems: prevalence of Salmonella spp. and E. coli O157:H7 in organically raised cattle and organic feed
Authors: Nazareth Joshua , Shaw Angela , Delate Kathleen , Turnbull Robert 
Published: December 2019

AbstractAvailability of organic foods has been increasing in the United States due to consumer demand for food produced with a lower environmental footprint. Surveys show that organic consumers view organic food as safer and of higher quality, but a number of food-borne outbreaks have been linked to organic produce in recent years. This outcome suggests that improved food safety protocols are needed to ensure food safety along organic food chains. In this study, model integrated crop–livestock organic systems were established in three states (Iowa, Minnesota and Pennsylvania) to evaluate biological performance and food safety aspects. Organically raised cattle and their feed/forage, feces, hide and meat were examined for the presence of two pathogens, Escherichia coli O157:H7 and Salmonella spp. Results confirmed that E. coli O157:H7 was not isolated on any hide or meat samples. Across all sites, the prevalence rate for E. coli O157:H7 on feed/forage and fecal matter was 9.43 and 7.26%, respectively. Salmonella spp. was isolated from 1.89, 3.33 and 18.6% of feed, fecal and hide samples, respectively. Salmonella spp. was not detected on any meat samples. While Salmonella spp. rates on hides were greater than those in feed and fecal samples, the prevalence rate of both pathogens on cattle hides was lower than in previous studies. The use of an organic fly repellent containing essential oils in this study would need to be investigated further to determine any correlation between its use and lower pathogen rates on hides. Feed/forage was more likely to test positive for E. coli O157:H7 from June through August, indicating the importance of strict sanitary measures to prevent feed contamination during summer months. These results suggest that careful adherence to food safety management strategies can help reduce the risk of bacterial contamination in integrated crop–livestock systems.
Moral Credentials, Intergroup Attitudes, and Regulatory Focus Interactively Affect Support for Affirmative Action
Authors: Lalot Fanny , Falomir-Pichastor Juan M. 
Published: December 2019

AbstractPeople generally tend to stay consistent in their attitudes and actions but can feel licensed to act less-than-virtuously when an initial moral action provides an excuse to do so (i.e., moral self-licensing). A handful of studies have tested how relevant initial attitudes moderate the self-licensing effect but yielded mixed findings: Initial attitudes either decrease, increase, or do not influence licensing dynamics. To account for these inconsistent findings, we propose that the effect of attitudes could itself interact with other factors, notably motivational orientation. We conducted two studies taking into account initial attitudes, absence/presence of moral credentials, and participants’ chronic regulatory focus. Drawing from self-completion theory, we expected self-licensing to occur specifically amongst prevention-focused participants holding positive intergroup attitudes. Results supported this prediction. Prevention-focused participants with positive intergroup attitudes supported affirmative action policies to a lesser extent when they had acquired moral credentials, as compared to when they had not (i.e., self-licensing),t(329) = –3.79,p< .001,d= –.42, 95% CI [–.64, –.20]. Additionally, promotion-focused participants holding positive intergroup attitudes supported affirmative action policies to a greater extent when they had acquired moral credentials (i.e., behavioral consistency),t(329) = 2.44,p= .015,d= .27, 95% CI [.05, .49].
The Particularly Vulnerable Situation of Women Living Homeless in Madrid (Spain)
Authors: Vázquez José Juan , Panadero Sonia , Pascual Isabel 
Published: December 2019

Abstract
People in homeless situation are one of the major embodiments of the phenomenon of social exclusion, and women living homeless are considered a particularly vulnerable group. This paper examines different variables that may affect the situation of vulnerability experienced by women living homeless in Madrid (Spain). The study was carried out using data obtained from a representative sample of homeless men in Madrid (n = 158) and a sample of homeless women in Madrid of a similar size (n = 138). The information was gathered using a structured interview in shelters or other facilities for people in a homeless situation, on the street and in other places not initially designed for sleeping. The results show that woman living homeless are highly vulnerable compared to the domiciled population and, in some respects, to homeless men as well, especially in the number of times homeless (χ2 = 10.314; p < .01), in the time working with a contract and/or self-employed (t = 5.754; p < .001), and in the use of sedatives (χ2= 14.741; p < .001). It is however noted that homeless women show in some aspects greater strengths than homeless men. Such strengths could serve as a supporting point for their social inclusion processes. The analysis of issues that differentiate women in a homeless situation from their male counterparts could be useful for developing public policies and care resources adapted to the specific characteristics and needs of women living homeless.
Future Changes in East Asian Summer Monsoon Circulation and Precipitation Under 1.5 to 5 °C of Warming

Published: December 2019

AbstractUnderstanding the link between future changes in East Asian summer monsoon (EASM) and global warming levels is of great importance for regional climate change adaptation and mitigation in East Asia. Here, we analyze the projected changes in EASM circulation and precipitation under different warming levels from 1.5 to 5 °C above the preindustrial global mean temperature, using large‐ensemble simulations conducted with Canadian Earth System Model version 2. We find that the model projects enhanced monsoon circulation and precipitation with global warming. The 850‐hPa meridional winds, precipitation, and 500‐hPa vertical ascending motion will be enhanced nonlinearly, while the total column precipitable water will increase quasi‐linearly. The increase in precipitable water in the wet EASM region is only slightly greater than global average but the increase in precipitation is much greater than global one, with enhanced 500‐hPa vertical ascending motion contrary to global mean. The increased low‐level land‐sea thermal contrast leads to the enhanced EASM meridional circulation and thus bring a large amount of moisture into Eastern China, providing favorable conditions for additional increase in precipitation. A simplified moisture budget analysis shows that the dynamic component related to strengthening monsoon circulation plays dominant role in the increase in EASM precipitation when the global temperature increases by more than approximately 2 °C, while the thermodynamic component caused by increased water vapor is important when the warming is smaller.

AbstractSoil degradation is a severe and growing threat to ecosystem services globally. Soil loss is often nonlinear, involving a rapid deterioration from a stable eco‐geomorphic state once a tipping point is reached. Soil loss thresholds have been studied at plot scale, but for landscapes, quantitative constraints on the necessary and sufficient conditions for tipping points are rare. Here, we document a landscape‐wide eco‐geomorphic tipping point at the edge of the Tibetan Plateau and quantify its drivers and erosional consequences. We show that in the upper Kali Gandaki valley, Nepal, soil formation prevailed under wetter conditions during much of the Holocene. Our data suggest that after a period of human pressure and declining vegetation cover, a 20% reduction of relative humidity and precipitation below 200 mm/year halted soil formation after 1.6 ka and promoted widespread gullying and rapid soil loss, with irreversible consequences for ecosystem services.
Iron Supply Pathways Between the Surface and Subsurface Waters of the Southern Ocean: From Winter Entrainment to Summer Storms

Published: December 2019

AbstractDissolved iron (DFe) plays an immeasurable role in shaping the biogeochemical processes of the open‐ocean Southern Ocean. However, due to observational constraints iron supply pathways remain poorly understood. Using an idealized eddy‐resolving physical‐biogeochemical model representing a turbulent sector of the Southern Ocean with seasonal buoyancy forcing and zonal winds overlaid by storms, we quantify the importance of a range of subsurface and surface iron supply mechanisms. The main physical supply pathways to the surface layer are via eddy advection and winter convective mixing in equal proportions. The associated subsurface loss of DFe is restocked via net remineralization (75%) and eddy advection (25%). Summer storms resulted in weak DFe supplies relative to the seasonal supplies (<7.6%). However, in situations of deep summer mixed layers and when interacting with underlying ocean fronts, summer storms resulted in enhanced diffusive and advective DFe supplies and raised summer primary production by 20% for several days.
Statistical Study of Energetic Electron Butterfly Pitch Angle Distributions During Magnetic Dip Events
Authors: Xiong Ying , Xie Lun , Fu Suiyan , Pu Zuyin 
Published: December 2019

AbstractThe magnetic dips can create the electron butterfly pitch angle distribution (PAD) in the inner magnetosphere. However, its universality is still unconfirmed. We statistically investigate the global distribution of the occurrence rate of the magnetic dip‐related butterfly PAD for 466 keV and 2.1 MeV electrons using the measurements of the twin Van Allen Probes spanning from September 2012 to November 2018. The statistical results show that the magnetic dip‐related butterfly PADs are mainly confined to duskside to midnight within 4.5 < L < 6, and the peak occurrence rate (30% for 466 KeV and 70% for 2.1 MeV) occurs at the duskside equator around L = 5. The parametric study results suggest that the butterfly PADs preferably occur for high energy electrons with a negative initial radial flux gradient and a nearly isotropic initial PAD, which is consistent with the statistic results. This work confirms the vital importance of the magnetic dips on the evolution of the electron PADs.

Published: December 2019

AbstractFor the comprehensive estimation of regional climate change over East Asia (EA) at the 2 and 3 °C global warming levels (GWLs), the Köppen‐Trewartha climate‐type change is assessed with ensemble regional climate change projections in line with Coordinated Regional Climate Downscaling Experiment (CORDEX)‐EA phase 2. Under the 2 °C (3 °C) GWL, 17.6% (25.2%) of the EA region is expected to undergo major climate‐type changes. Tropical and subtropical climate types will expand northward, accompanied by increasing hydroclimatic intensity. Limiting GWL to 2 °C shows benefits by preventing subtropical‐type expansion around far EA. Desertification over inland regions of EA exhibits scenario dependency. Boreal and tundra climate types over high‐latitude regions will tend to decrease rapidly, especially over the Tibetan Plateau. The results are expected to be a baseline assessment of climate change over EA under the 2 and 3 °C GWLs above the preindustrial level.
Spatial Characteristics of Mesoscale Plasma Flow Perturbations and Accompanying Electron Precipitation in the High‐Latitude Ionosphere
Authors: Chen Yun‐Ju , Heelis Roderick A. 
Published: December 2019

AbstractThe spatial characteristics of mesoscale plasma perturbations in the high‐latitude ionosphere are important considerations for a more complete description of the energy deposition from the magnetosphere. In this study, ion drift and particle precipitation measurements from the Defense Meteorological Satellite Program F17 satellite during local summer seasons in 2012 are used to examine the flow perturbations and their closure paths and the particle precipitation associated with them. The closed circulation associated with a flow perturbation is identified from the potential distribution and can be described by a single‐cell or a two‐cell configuration with characteristic spatial scale sizes between 100 and 600 km and 200 and 1,200 km, respectively. Observations suggest that an asymmetry in space and flow speed is frequently seen with faster flows in a narrower region and slower return flows in wider adjacent regions. For a single‐cell configuration, the faster flows are preferentially sunward and in the same direction as the background convection, and the weaker return flows are preferentially duskward/dawnward of the potential maxima/minimum. For a two‐cell configuration, the faster flow is seen in the central region and also tends to follow the background convection with weaker return flows on the two sides. Except in the region poleward of the convection reversal boundary, 0.5–3 keV electron precipitation, displaying the same spatial asymmetry as the flow perturbation, is frequently seen in a single cell around a potential minimum on the dusk side.
