Published: November 2020

ABSTRACTVisualising the loads that a structure can tolerate provides a key insight into the structural design process, especially for materials and structures that are governed by complex failure criteria. This paper proposes a general method for efficient construction of performance envelopes in load space, and demonstrates the approach with two examples. The performance envelope identifies all possible failure modes, all the redundant and non-redundant structural constraints, and the limiting failure mode in a particular direction in load space. Once the envelope has been constructed, the structural reserve factors can be calculated extremely quickly. In design such envelopes are most useful for structural analysis processes which involve a very large number of load cases, and where the cost of constructing an envelope for a given feature is relatively modest.

Published: November 2020

AbstractMulticomponent polymer systems are of interest in organic photovoltaic and drug delivery applications, among others where diverse morphologies influence performance. An improved understanding of morphology classification, driven by composition-informed prediction tools, will aid polymer engineering practice. We use a modified Cahn–Hilliard model to simulate polymer precipitation. Such physics-based models require high-performance computations that prevent rapid prototyping and iteration in engineering settings. To reduce the required computational costs, we apply machine learning (ML) techniques for clustering and consequent prediction of the simulated polymer-blend images in conjunction with simulations. Integrating ML and simulations in such a manner reduces the number of simulations needed to map out the morphology of polymer blends as a function of input parameters and also generates a data set which can be used by others to this end. We explore dimensionality reduction, via principal component analysis and autoencoder techniques, and analyze the resulting morphology clusters. Supervised ML using Gaussian process classification was subsequently used to predict morphology clusters according to species molar fraction and interaction parameter inputs. Manual pattern clustering yielded the best results, but ML techniques were able to predict the morphology of polymer blends with ≥90% accuracy.

AbstractCallery pear (Pyrus calleryanaDecne.) is rapidly spreading in the United States, gaining attention in the last two decades as a serious invasive pest. Recommended control methods include foliar, basal bark, cut stump, and hack-and-squirt application of herbicides, but there are few published studies with replicated data on efficacy. Four readily available herbicidal active ingredients and a combination of two active ingredients were tested for control efficacy againstP. calleryanain old-field areas and loblolly pine (Pinus taedaL.) understory. Basal bark applications (triclopyr, triclopyr + aminopyralid), foliar applications (glyphosate, imazapyr), and a soil application (hexazinone) effectively killedP. calleryanawith the exception of hexazinone at one site, where rainfall may not have been optimal. Foliar application of glyphosate provided the most consistent control. Our results demonstrate efficacy of registered herbicide formulations forP. calleryanacontrol in two geographic locations and two habitat types. The need for development of integrated pest management programs forP. calleryanais discussed.
Influences on adolescent help-seeking for mental health problems
Authors: Pearson Sarah , Hyde Chelsea 
Published: November 2020

AbstractSeeking help for mental health concerns is critical for improving wellbeing and preventing the development of mental health disorders, yet many adolescents with mental health problems fail to seek professional help. It is well established that young people with mental health problems face a variety of barriers to help-seeking; however, little is known about the ways in which these barriers interact to impact upon the help-seeking process. Guided by the reasoned action approach, this study investigated the predictive relationship between factors that influence help-seeking. Results revealed that mental health knowledge significantly predicted help-seeking intentions, while attitudes did not. Gender differences were identified for help source preferences. The current study contributes to knowledge on the relationship between key variables that influence the adolescent help-seeking process. Findings highlight the importance of mental health knowledge in predicting help-seeking intentions and provide support for interventions that focus on improving mental health literacy in adolescents.

AbstractVegetables are an important source for the essential vitamins and minerals that are necessary for optimal health. This research investigated changes in vegetable intake over time in the Korean population from 1998 to 2017, focusing on preparation methods of vegetables and location of consumption. This cross-sectional study is based on the Korea National Health and Nutrition Examination Survey (KNHANES) that was established in 1998 to assess the health and nutritional status of the South Korean population. This research utilised information from 1998 to 2017 which is the extent of all available KNHANES data. Vegetable consumption was grouped, according to preparation methods and common eating locations. Both crude and age-standardised means of vegetable intake were derived via a 24-h dietary recall. All participants who completed a 24-h dietary recall survey were selected for the analyses. This included 109 220 individuals (49 069 men and 60 151 women) over the course of 20 years of the KNHANES. Total vegetable intake decreased over time (Pfor trends < 0·001), specifically, steamed and salted vegetables (Pfor trends < 0·001). In contrast, Koreans consumed noticeably more raw vegetables from 1998 to 2017 (Pfor trends < 0·001). Vegetable intake at home significantly declined (Pfor trends < 0·001), while that eaten at restaurants or outside the home increased greatly (Pfor trends < 0·001). Over 20 years, Koreans have ingested decreasing amounts of vegetables, but the intake of raw vegetables has escalated. However, the location of vegetable consumption has changed, with an increase at both restaurants and outside the home (approximately 70·0 %).

AbstractCoronavirus disease 2019 (COVID-19) has rapidly spread globally, forcing countries to apply lockdowns and strict social distancing measures. The aim of this study was to assess eating habits and lifestyle behaviours among residents of the Middle East and North Africa (MENA) region during the lockdown. A cross-sectional study among adult residents of the MENA region was conducted using an online questionnaire designed on Google Forms during April 2020. A total of 2970 participants from eighteen countries participated in the present study. During the pandemic, over 30 % reported weight gain, 6·2 % consumed five or more meals per d compared with 2·2 % before the pandemic (P < 0·001) and 48·8 % did not consume fruits on a daily basis. Moreover, 39·1 % did not engage in physical activity, and over 35 % spent more than 5 h/d on screens. A significant association between the frequency of training during the pandemic and the reported change in weight was found (P < 0·001). A significantly higher percentage of participants reported physical and emotional exhaustion, irritability and tension either all the time or a large part of the time during the pandemic (P < 0·001). Although a high percentage of participants reported sleeping more hours per night during the pandemic, 63 % had sleep disturbances. The study highlights that the lockdown due to the COVID-19 pandemic caused a variety of lifestyle changes, physical inactivity and psychological problems among adults in the MENA region.
An ‘Institution-First’ Conception of Public Integrity
Authors: Kirby Nikolas 
Published: November 2020

AbstractThere is an emerging drive to define a new praiseworthy governance goal: a goal that not only implies addressing corruption but going further to establish institutions that are truly worthy of trust. That goal is ‘public integrity’. However, most current accounts of public integrity adopt an ‘officer-first’ approach: defining public integrity primarily as a quality of individual public officers, and only derivatively, if at all, as a quality of public institutions themselves. This article argues that this approach is flawed. Analysing the current debate, it identifies the need to define a role-specific sense of praiseworthy behaviour for public officers. However, it is only possible to define this role-specific sense of praiseworthy behaviour by referring to a public officer's contribution to the overall moral ideal of her institution. Assuming that this ideal itself is a form of public integrity, it then follows that such institutional integrity must be defined ‘first’ in order to then define a public officer's praiseworthy contribution to it second. Substantively, this article argues that ‘public institutional integrity’ is an institution's robust disposition to pursue its purpose efficiently, within the constraints of legitimacy, consistent with its commitments. ‘Public officer integrity’ is the robust disposition of an officer to support the integrity of her institution, within the course of her duties, to the best of her abilities.
Conversionary Protestants Do Not Cause Democracy
Authors: Nikolova Elena , Polansky Jakub 
Published: November 2020

AbstractIn The Missionary Roots of Liberal Democracy, Robert D. Woodberry (2012) claims that conversionary Protestantism influenced the emergence of stable democracies around the world. While his historical analysis is exhaustive, the accompanying empirical evidence suffers from severe inconsistencies. This letter replicates Woodberry's analysis using twenty-six alternative democracy measures and extends the time period over which the democracy measures are averaged. These two simple modifications lead to the breakdown of Woodberry's results. We find no significant relationship between Protestant missions and the development of democracy, which raises concerns about the robustness and broader applicability of Woodberry's findings. The letter discusses some alternative explanations for Woodberry's results, which can inform future research on this topic.

Published: November 2020

AbstractLongan is an economically important sub-tropical fruit tree native to southern China and southeast Asia. Its production has been affected significantly by climate change, but the underlying reasons remain unclear. Herein, the potential growing areas of longan were simulated by the Maxent model under current and future conditions. The results showed excellent prediction performance, with an area under curve of >0.9 for model training and validation. The key environmental variables identified were mean temperature of the coldest quarter, minimum temperature of the coldest month, annual mean temperature and mean temperature of the driest quarter. The optimum suitable areas of longan were found to be concentrated mainly in south-western, southern and eastern China, with a slight increase in optimum suitable areas under two different emission scenarios of three global climatic models. However, its future potential growing areas were predicted to differ among provinces or cities. Suitable growing areas in Sichuan, Jiangxi, Guangxi and Chongqing will first increase and then remain approximately unchanged between the 2050s and 2070s; those in Yunnan, Guangdong and Hainan will remain approximately unchanged from the present to the 2070s; those in Fujian and Guizhou will fluctuate slightly from the present to the 2050s and then increase to the 2070s; those in Taiwan will first decrease and then increase. In summary, the major future production areas of longan will be Guangdong, Hainan and Guangxi provinces, followed by Chongqing, Yunnan, Fujian and Taiwan. Thus, this study serves as a useful guide for the management of longan.
Bacterial starter cultures induce suitable changes in milk fatty acid profiles at different fermentation conditions

Published: November 2020

AbstractThis study aimed to compare the effect of different ratios of Streptococcus thermophilus to Lactobacillus bulgaricus (3 : 1, 1 : 1, and 1 : 3) under the various stressful temperatures (37 and 45°C) on the fatty acid profiles quality of Kermanshahi roghan (yogurt by-product) and sour cream to obtain a formula for producing a kind of animal fat healthier than milk and cream. Stresses such as fermentation play an important role in bacterial behavior and consequently in food quality. Our findings presented a significant difference between roghan and sour cream fatty acid levels only at 37°C. Furthermore, starter culture 3 : 1 was the best starter for producing products with a higher quality of fatty acid profile at 37°C, and a 1 : 1 S. thermophilus to L. bulgaricus ratio was optimal at 45°C. It seems that bacteria adapt to harsh growth conditions by changing the fatty acid profiles, and these changes warrant consideration in the production of a kind of animal fat with the best fatty acid profiles. In conclusion, the roghan fatty acid profile is more suitable than sour cream only at 37°C.

Published: November 2020

Abstract
Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a debilitating condition, characterised by unexplained and excessive fatigue, muscle pain and sleep disturbances. Health anxiety is common in ME/CFS and accurate measurement is essential in facilitating therapeutic gains. However, there are clinical concerns over the utility of the Short Health Anxiety Inventory (SHAI) in measuring health anxiety in this population. This study aims to use qualitative responses from two ex-service users and specialist health clinicians to explore the barriers to completing the SHAI within a specialist ME/CFS service. Qualitative responses from a focus group consisting of 15 specialist health professionals including occupational therapists, physiotherapists, dieticians, cognitive behavioural therapists, counsellors, clinical psychologists and assistant psychologists were transcribed and analysed for themes. Patient voices were represented by two former service users through individual semi-structured interviews on the telephone, which were recorded, transcribed and later analysed thematically. Clinicians and service user involvement agreed on core difficulties with the utility of the SHAI in the ME/CFS population. The timing of the SHAI being administered pre-diagnosis, the language of the SHAI and lack of context around the questionnaire were identified as barriers that were likely to contribute to the SHAI not being completed by service users. Sensitive and accurate measurement is required in order to retain patient engagement, which could further facilitate appropriate assessment and treatment of health anxiety and ME/CFS. Findings suggest that adaption of the SHAI is vital for use with ME/CFS.

Key learning aims

AbstractInternational Ocean Discovery Program Expedition 352 to the Bonin forearc drilled the sequence of volcanic rocks erupted in the immediate aftermath of subduction initiation along the western margin of the Pacific Plate. Pristine volcanic glasses collected during this expedition were analyzed for major and trace elements, halogens, sulfur, and H and O isotopes with goals of characterizing the fluids and melts of subducted materials that were involved in generating the nascent upper plate crust. Incompatible trace element compositions of the oldest lavas (forearc basalts [FAB]) are similar to those of the most depleted mid‐ocean ridge basalts globally. Most FAB were generated by decompression melting during seafloor spreading in a near‐trench, supra‐subduction zone environment with only minor involvement of diverse and generally dilute water‐rich fluids from the subducting plate. Boninite series glasses are enriched in incompatible trace elements mobilized from the subducting plate, but strongly depleted in other elements, such as the middle‐heavy rare‐earth elements. These traits are attributed to generation of boninites largely by flux melting involving water‐rich melts first derived from the leading edge of subducted basaltic crust and then from both subducted crust and sediment. These melts were generated at low pressures as the shallow, embryonic slab extracted heat from hot asthenosphere near the trench. The progressive depletion of the mantle source for the FAB‐through‐boninite sequence suggests that the asthenospheric mantle remained trapped above the nascent subducting plate for the first several million years of subduction beneath the Philippine Sea Plate.

AbstractWe report the seasonal variability of temperature, nutrients, and total and size‐fractionated chlorophyll‐a (Chl‐a) in nearshore waters off northern Baja California (nBC), under conditions of the marine heatwave and El Niño that occurred in the northeastern Pacific during 2014–2015. Compared with the mean annual cycle (2008–2015), our study period was characterized by warmer waters, nitrate‐impoverished, and with very low Chl‐a concentration, which was closely associated with strong stratification and reduced upwelling conditions off nBC. Temperature anomalies were >2.0°C by the end of 2014 when the marine heatwave prevailed, decreased during the spring‐early summer upwelling season of 2015, and returned to >2.5°C by the end of 2015 when El Niño appeared along the coast of nBC. As in 2008–2012 and closely coupled with upwelling, a seasonal cycle of total Chl‐a was recorded under these abnormally warm conditions. However, relative to the mean annual cycle, total Chl‐a and nitrate concentrations were significantly reduced (19%–55% and 40%–81%, respectively), with negative anomalies throughout the study period. Moreover, the seasonal evolution of the size‐fractionated Chl‐a concentration showed that smaller cells (<5 μm) systematically contributed with the largest fraction (>60%) of the total Chl‐a. Our findings indicate that the sequential occurrence of the marine heatwave in 2014 and El Niño in 2015 had a significant and sustained impact limiting the nitrate supply and reducing the total Chl‐a in nearshore waters off nBC. In conclusion, our data reveal that a shift toward an oligotrophic state occurred in coastal waters off nBC during the warm period of 2014–2015.

AbstractA high proportion of noncrystalline (X‐ray‐amorphous) components has been found in all samples analyzed by CheMin on theCuriosity roverat Gale crater on Mars, and such X‐ray‐amorphous components probably occur at all sites that have been investigated thus far by landers and rovers. The amorphous material at Gale crater is rich in volatiles (S, Cl, and H2O), as indicated by other science payload elements (APXS, SAM). We demonstrate here that amorphization of S and Cl salts can be induced by energetic electrons and free radicals generated in a medium‐strength electrostatic discharge (ESD) process during Martian dust activities such as dust storms, dust devils, and grain saltation. Furthermore, we found that the amorphization is commonly accompanied by dehydration of the salts and oxidation of Cl, S, and Fe species. On the basis of experimentally observed rates of the above phase transformations and the mission‐observed dust activities and wind speeds on Mars, we anticipate that similar phase transformations could occur on Mars within a time frame of years to hundreds of years. Considering the high frequency, long duration, and large areal coverage of Martian dust activities, our study suggests that the ESD induced by Martian dust activities may have contributed to some the S‐ and Cl‐rich portion of X‐ray amorphous materials observed in surface soils at Gale crater. Furthermore, dust activities in the Amazonian period may have generated and deposited a significant quantity of S‐ and Cl‐rich amorphous materials all over Mars.
