Self-powered flexible pressure sensors based on nanopatterned polymer films
Authors: Zhang Man , Xia Liangping , Dang Suihu , Shi Lifang , Cao Axiu , Du Chunlei 
Published: October 2020

Purpose
The pressure sensors can convert external pressure or mechanical deformation into electrical power and signal, which cannot only detect pressure or strain changes but also harvest energy as a self-powered sensor. This study aims to develop a self-powered flexible pressure sensor based on regular nanopatterned polymer films.

Design/methodology/approach
In this paper, the self-powered flexible pressure sensor is mainly composed of two nanopatterned polymer films and one conductive electrode layer between them, which is a sandwich structure. The regular nanostructures increase the film roughness and contact area to enhance the friction effect. To enhance the performance of the pressure sensor, different nanostructures on soft polymer sensitive layers are fabricated using UV nanoimprint lithography to generate more triboelectric charges.

Findings
Finally, the self-powered flexible pressure sensor is prepared, which consists of sub-200 nm resolution regular nanostructures on the surface of the elastic layer and an indium tin oxide electrode thin film. By converting the friction mechanical energy into electrical power, a maximum power of 423.8 mW/m2 and the sensitivity of 0.8 V/kPa at a frequency of 5 Hz are obtained, which proves the excellent sensing performance of the sensor.

Originality/value
The acquired electrical power and pressure signal by the sensor would be processed in the signal process circuit, which is capable of immediately and sustainably driving the highly integrated self-powered sensor system. Results of the experiments show that this new pressure sensor is a potential method for personal pressure monitoring, featured as being wearable, cost-effective, non-invasive and user-friendly.

Authors: Zhang Jiangchi , Xie Chaowu , Morrison Alastair M. , Yang Qinqin 
Published: October 2020

Purpose
This research divided expectations into three timeframes based on expectancy theory – short-, medium- and long-term. The incentive-motivation structures of government tourism officers were identified by these timeframes and the effects of incentives on job engagement, performance and satisfaction were investigated.

Design/methodology/approach
A survey was conducted in 31 provinces of China, and a total of 650 responses were used for data analysis after removing invalid surveys. The statistical analysis techniques adopted were confirmatory factor analysis, correlation analysis and structural equation modeling.

Findings
The results showed that: realistic motivations, career prospects and “macro-vision” were the motivational factors of tourism officers in the short-, medium- and long-term, respectively; incentives positively predicted tourism officer job engagement, performance and satisfaction; and job engagement and performance mediated the influence of incentives on job satisfaction.

Research limitations/implications
The main limitation was that the respondents were from 31 provinces in China, and there may be regional and local differences due to the unique and complex geographic and social conditions, as well as dissimilar economic development levels and administrative systems.

Practical implications
Public sector tourism departments must recognize tourism officer needs and motivations in the short-, medium- and long-term and develop tailored incentive programs.

Originality/value
Based on expectancy theory across different timeframes, this research identified the incentive-motivation structure and its effect on Chinese destination management organization officers and potentially provides a theoretical basis for the optimization of this administrative incentive system.

AbstractIn the dermoscopic diagnosis of skin tumors, it remains unclear whether a deep neural network (DNN) trained with images from fair‐skinned‐predominant archives is helpful when applied for patients with darker skin. This study compared the performance of 30 Japanese dermatologists with that of a DNN for the dermoscopic diagnosis of International Skin Imaging Collaboration (ISIC) and Shinshu (Japanese only) datasets to classify malignant melanoma, melanocytic nevus, basal cell carcinoma and benign keratosis on the non‐volar skin. The DNN was trained using 12 254 images from the ISIC set and 594 images from the Shinshu set. The sensitivity for malignancy prediction by the dermatologists was significantly higher for the Shinshu set than for the ISIC set (0.853 [95% confidence interval, 0.820–0.885] vs 0.608 [0.553–0.664], P < 0.001). The specificity of the DNN at the dermatologists’ mean sensitivity value was 0.962 for the Shinshu set and 1.00 for the ISIC set and significantly higher than that for the human readers (both P < 0.001). The dermoscopic diagnostic performance of dermatologists for skin tumors tended to be less accurate for patients of non‐local populations, particularly in relation to the dominant skin type. A DNN may help close this gap in the clinical setting.

AbstractIn situ accurate data sets of leaf area index (LAI), above‐ground biomass (AGB), and fraction of absorbed photosynthetically active radiation (fAPAR) are indispensable to validate and improve ecological products obtained from satellites. In situ data for satellite validation must be created not from a single‐point data but from areal data (such as multiple‐points data) representing a satellite footprint. Using multiple‐points data, the error of in situ data can be calculated statistically. The quantification of the error in the in situ data enables us to evaluate the discrepancy between the satellites' products and the in situ data as the error in the in situ data and the estimation error in the products separately. Besides, the accuracy of the in situ data is required to be much higher than the accuracy of the satellite products which was officially set. To obtain such in situ data, we have established observation sites for typical land cover types in East Asia, from temperate to cool ecosystems: deciduous needle‐leaved forest (DNF), evergreen needle‐leaved forest (ENF), deciduous broad‐leaved forest (DBF), and grassland (GL). We conducted the observations in 500 m × 500 m areas, which is the footprint scale of the Global Change Observation Mission‐Climate satellite. In this paper, the data of LAI, AGB, and fAPAR observed at DNF, DBF, and GL (i.e., except at ENF) are reported. These data are useful even for the validation of other satellite products, especially with higher spatial resolution. Also, the long‐term tree census data from 2005 to 2018 at DNF are reported.The complete data set for this abstract published in the Data Paper section of the journal is available in electronic format in MetaCat in JaLTER at http://db.cger.nies.go.jp/JaLTER/metacat/metacat/ERDP-2020-16.1/jalter-en.
Specimen‐based records of geometrid, pyralid and crambid moths (Lepidoptera) with location information from the collection of Dr. Hiroshi Inoue

Published: October 2020

AbstractAs moths of the geometrid group usually live in forests and do not move long distances, they are considered to be valuable as environmental bio‐indicators. Biodiversity data based on voucher specimens should have high quality and reliability. Here, we publish the records of the family Geometridae and the superfamily Pyraloidea (Pyralidae and Crambidae) with time of collection and location information, that is, latitude and longitude on the basis of the collection of Dr. Hiroshi Inoue deposited at Institute for Agro‐Environmental Sciences, NARO (NIAES). The collection of Geometridae covers 653 records from 615 species, collected from 1926 to 1979. The collection of Pyraloidea covers 447 records from 418 species, collected from 1949 to 1985. For the purpose, all users can access the data from the Global Biodiversity Information Facility (GBIF) portal site with open data license CC BY 4.0; all data is published in the GBIF through the Japan node of GBIF (JBIF).The detailed Metadata for this abstract published in the Data Paper section of the journal is available in MetaCat in JaLTER at http://db.cger.nies.go.jp/JaLTER/metacat/metacat/ERDP-2020-21.1/jalter-en.
Characterization of the bacterial microbiomes of social amoebae and exploration of the roles of host and environment on microbiome composition
Authors: Sallinger Eleni , Robeson Michael S. , Haselkorn Tamara S. 
Published: October 2020

SummaryAs predators of bacteria, amoebae select for traits that allow bacteria to become symbionts by surviving phagocytosis and exploiting the eukaryotic intracellular environment. Soil‐dwelling social amoebae can help us answer questions about the natural ecology of these amoeba‐bacteria symbioses along the pathogen‐mutualist spectrum. Our objective was to characterize the natural bacterial microbiome of phylogenetically and morphologically diverse social amoeba species using next‐generation sequencing of 16S rRNA amplicons directly from amoeba fruiting bodies. We found six phyla of amoeba‐associated bacteria: Proteobacteria, Bacteroidetes, Actinobacteria, Chlamydiae, Firmicutes, and Acidobacteria. The most common associates of amoebae were classified to order Chlamydiales and genus Burkholderia‐Caballeronia‐Paraburkholderia. These bacteria were present in multiple amoeba species across multiple locations. While there was substantial intraspecific variation, there was some evidence for host specificity and differentially abundant taxa between different amoeba hosts. Amoebae microbiomes were distinct from the microbiomes of their soil habitat, and soil pH affected amoeba microbiome diversity. Alpha‐diversity was unsurprisingly lower in amoebae samples compared with soil, but beta‐diversity between amoebae samples was higher than between soil samples. Further exploration of social amoebae microbiomes may help us understand the roles of bacteria, host, and environment on symbiotic interactions and microbiome formation in basal eukaryotic organisms.
Sister Communities: Rejecting Labels of Informality and Peripherality in Vanuatu
Authors: Day Jennifer 
Published: October 2020

AbstractSome labels have dire consequences. This article takes issue with the labels commonly used to describe the physical and social location of communities living on the edge of Port Vila, Vanuatu—labels that position communities for eviction by entrenching tropes of informality and peripherality into how they are seen and represented. Such terms include informal, settlement, informal settlement, squatter and peri‐urban. Based on interviews with around 100 people and two years of ethnographic engagement with urban communities in Port Vila, Vanuatu, I critique the language of policy against the lived experience of those at the urban edge. I use Bourdieu's articulation of power as an accumulation of symbolic capital that enables one to speak the world into being. I conclude that the language of policies and plans is reflective of a dominant discourse in urban studies and international aid, and non‐reflective of the experience and identities of people living at the urban edge. My interviewees and interlocutors maintain their identities as sister communities—as places grounded in the formality of customary tenure, and as part of the city rather than outside it.
Towards an understanding of dialectical authenticity of historic landscapes in China
Authors: Yang Chen , Lawson Gillian , Sim Jeannie , Han Feng 
Published: October 2020

AbstractThis article explores stakeholders' understandings of authenticity in a selected historic landscape of China, and focuses on views about appropriate conservation and management strategies. The World Heritage listed site, Slender West Lake Scenic and Historic Interest Area, is examined as a case study. The study shows that various stakeholders think the originality of fabric, the representation of intangible values, and social engagement are three major indicators of the authenticity of this historic landscape. The finding leads us to suggest that, in China, authenticity is significantly influenced by specific social, political, and economic factors and by native Chinese philosophies and the cultural characteristic of naïve dialecticism, which partly explains contemporary conservation practices there. The case study also demonstrates that creative reconstruction has always been an important cultural practice in the history and geography of the Slender West Lake site. However, the superficial application of this cultural practice may create challenges for contemporary landscape conservation. The concept of dialectical authenticity therefore has implications for future conservation practices of historic landscapes.
Distal‐type bronchiolar adenoma of the lung harboring an EGFR exon 21 p.L858R mutation: A case report
Authors: Yang Chenglin , Wang Xiaoliang , Da Jiping , Ma Kai 
Published: October 2020

Here, we present a case of a distal‐type bronchiolar adenoma (BA) of the lung. BAs are benign lung tumors characterized by nodular proliferation of bilayered bronchiolar‐type epithelium with a continuous layer of basal cells. This patient underwent S3 segmentectomy following detection by computed tomography (CT) scan of a gradually enlarging ground‐glass nodule (GGO) over a five month period. Nodule morphology and immunophenotype were consistent with those of distal‐type BA of the lung. An epidermal growth factor receptor (EGFR) exon 21 p.L858R missense mutation was identified which, to the best of our knowledge, is the first case to be reported of a common gene mutation associated with non‐small cell lung cancer (NSCLC) being found in a BA lesion. Following surgery, the patient remains relapse‐free.Key pointsSignificant findings of the study
Pathological assessment of a lung nodule confirmed a papillary tumor with a double‐layered cell structure, less than typical cytoplasm, and a mixture of ciliated columnar and globular cells, consistent with a distal‐type bronchiolar adenoma.
What this study adds
This is the first report of an EGFR exon 21 p.L858R mutation in a bronchiolar adenoma.
The risk of complications in second pregnancy by maternal BMI: The role of first‐pregnancy complications, pregestational diabetes and chronic hypertension
Authors: Sormunen‐Harju Heidi , Koivusalo Saila , Gissler Mika , Metsälä Johanna 
Published: October 2020

AbstractIntroductionMaternal obesity is associated with an increased risk of several pregnancy complications. In the second pregnancy, previous pregnancy and other medical history provide additional information about individual morbidity risk. In this study, we assess the risk of pregnancy complications in the second pregnancy by maternal body mass index (BMI) and evaluate how first‐pregnancy complications and preexisting conditions modify these associations.Material and methodsWe have used nationwide data on all women (n = 48 963) experiencing their first and second pregnancy between 2006 and 2013 in Finland. The associations between the full scale of maternal BMI and pregnancy complications (gestational diabetes, gestational hypertension and preeclampsia) were analyzed using logistic regression and restricted cubic spline regression models and interactions between BMI and first‐pregnancy complications, pregestational diabetes or chronic hypertension were tested.ResultsThe risk of pregnancy complications increased with adiposity. Unadjusted probability of second‐pregnancy gestational diabetes with BMI of 25 kg/m2 was 56% and 8.4% among women with and without first‐pregnancy gestational diabetes, respectively. The corresponding figures with BMI of 30 kg/m2 were 64% and 17%. Adjusted odds ratio (OR) (95% CI) for second‐pregnancy gestational diabetes with BMI of 25 kg/m2 was 45 (34‐59) and 3.3 (2.6‐4.0) among women with and without first‐pregnancy gestational diabetes, respectively, when compared with women with BMI of 20 kg/m2 and no first‐pregnancy gestational diabetes. Adjusted OR (95% CI) for second‐pregnancy gestational hypertension among women with BMI of 25 kg/m2 was 42 (26‐66) and 2.3 (1.4‐3.8) among women with and without first‐pregnancy hypertensive disorder, respectively, when compared with women with BMI of 20 kg/m2 and no first‐pregnancy hypertensive disorder. The risk of preeclampsia increased with adiposity independent of first‐pregnancy complications. Pregestational diabetes or chronic hypertension did not modify the association between adiposity and any of the second‐pregnancy complications.ConclusionsAs maternal BMI increases, the risk of complications increases in the second pregnancy. The risk of gestational diabetes and hypertension is, however, highest among women with complications in the first pregnancy.

Published: October 2020

Salivary gland tumours (SGT) are a vast and heterogenous group of neoplasms. There is a relative lack of comprehensive nationwide epidemiological studies on the subject. The aim of this nationwide analysis was to gain insight into epidemiological traits, such as site, incidence and histological subtypes of SGT in general. Patients diagnosed with a primary SGT between 1986 and 2015 were identified from The Icelandic Cancer Registry and registries from all pathology departments in Iceland. Information on age, sex, tumour location and histology was retrieved from pathology reports. A total of 687 patients were diagnosed with a SGT, 609 (89%) were benign and 78 (11%) malignant. 9% of parotid gland tumours, 22% of submandibular gland tumours and 26% of minor SGT were malignant. The most common malignant tumours were mucoepidermoid carcinoma, acinic cell carcinoma and adenoid cystic carcinoma. The incidence of benign SGT was 4.9 per 100 000 among men and 7.0 per 100 000 among women. The incidence of malignant tumours was 0.59 per 100 000 for men and 0.79 per 100 000 for women. The proportion of malignant SGT is lower than most often reported. Only 10% of parotid gland tumours, 20% of submandibular gland tumours and 25% of minor salivary gland tumours are malignant.

Published: October 2020

AbstractSolitary primary pelvic intraperitoneal hydatid cysts are rare. We report the case of a 22‐year‐old women who presented with a dull ache in her lower abdomen for 2 years and increased urinary frequency over 3 months. Ultrasonography and CT indicated a solitary primary peritoneal pelvic hydatid cyst. Hydatid serology was positive. Perioperative albendazole was prescribed and laparoscopic cystectomy planned. Intraoperatively, dense adhesions to the omentum, urinary bladder, and left fallopian tube were taken down laparoscopically. A small Pfannenstiel incision was made to separate the bladder's left lateral edge and deliver the cyst externally. This report details our experience of managing this case and reviews pertinent literature.

Published: October 2020

SummaryHigh‐dose chemotherapy (HDC) and autologous stem cell transplantation (ASCT) are used as consolidation in first remission (CR1) in some centres for untreated, transformed indolent B‐cell lymphoma (Tr‐iNHL) but the evidence base is weak. A total of 319 patients with untreated Tr‐iNHL meeting prespecified transplant eligibility criteria [age <75, LVEF ≥45%, no severe lung disease, CR by positron emission tomography or computed tomography ≥3 months after at least standard cyclophosphamide, doxorubicin, vincristine and prednisolone with rituximab (R‐CHOP) intensity front‐line chemotherapy] were retrospectively identified. Non‐diffuse large B‐cell lymphoma transformations were excluded. About 283 (89%) patients had follicular lymphoma, 30 (9%) marginal‐zone lymphoma and six (2%) other subtypes. Forty‐nine patients underwent HDC/ASCT in CR1, and a 1:2 propensity‐score‐matched cohort of 98 patients based on age, stage and high‐grade B‐cell lymphoma with MYC, BCL2 and/or BCL6 rearrangements (HGBL‐DH) was generated. After a median follow‐up of 3·7 (range 0·1–18·3) years, ASCT was associated with significantly superior progression‐free survival [hazard ratio (HR) 0·51, 0·27–0·98; P = 0·043] with a trend towards inferior overall survival (OS; HR 2·36;0·87–6·42; P = 0·1) due to more deaths from progressive disease (8% vs. 4%). Forty (41%) patients experienced relapse in the non‐ASCT cohort — 15 underwent HDC/ASCT with seven (47%) ongoing complete remission (CR); 10 chimeric antigen receptor‐modified T‐cell (CAR‐T) therapy with 6 (60%) ongoing CR; 3 allogeneic SCT with 2 (67%) ongoing CR. Although ASCT in CR1 improves initial duration of disease control in untreated Tr‐iNHL, the impact on OS is less clear with effective salvage therapies in this era of CAR‐T.
Migration as a test of the happiness set‐point hypothesis: Evidence from immigration to Canada and the United Kingdom
Authors: Helliwell John F. , Shiplett Hugh , Bonikowska Aneta 
Published: October 2020

AbstractStrong versions of the set‐point hypothesis argue that subjective well‐being measures reflect primarily each individual's own personality and that deviations are temporary. International migration provides an excellent test, since life circumstances and subjective well‐being differ greatly among countries. With or without adjustments for selection effects, the levels and distributions of immigrant life‐satisfaction scores for immigrants to the United Kingdom and Canada from up to 100 source countries mimic those in their destination countries, and even the destination regions within those countries, rather than those in their source countries, showing that subjective life evaluations are substantially driven by life circumstances and respond when those circumstances change.
