Exploring post-pandemic struggles and recoveries in the rural tourism based on Chinese situation: a perspective from the IAD framework
Authors: Pan Haiying , Chen Meihong , Shiau Wen-Lung 
Published: August 2021

Purpose
The public health emergency of COVID-19 (Corona-virus disease) pandemic has greatly impacted tourism industry, especially in the rural tourism. This paper aims to study how rural tourism practitioners can get out of the mire of the pandemic. By analyzing the behaviors of various stakeholders and the logic of the impact of the pandemic, the behaviors of participants and future development were sorted out. The key elements that promote the recovery of rural tourism were discovered.

Design/methodology/approach
Based on the framework of institute analysis and development (IAD), this research selected six rural tourist communities in China as subjects for the studies. Based on the seven basic principles of hermeneutics and the inductive research method, following the analysis method of “first-order coding, second-order coding, aggregated dimensions,” the texts obtained through in-depth interview and work reports were analyzed and concepts were extracted.

Findings
The paper extracted 44 first-order concepts and 14 second-order concepts, and obtained 7 aggregation dimensions, including policy formulation and implementation, improvement of integrated marketing capabilities, improvement of tourism product quality, restrictions on rural tourism development, protection and optimization of environmental resources, industrial integration strategies and improvement of managerial and coordinating capabilities. During the pandemic, the government, enterprises and associations, as the service providers of rural tourism, can optimize the environmental resources and industrial resources of rural tourism by formulating policies, refining products and strengthening marketing in the action arena, to promote the industrial integration of rural tourism and provide better products and services for tourists.

Originality/value
This paper uses the IAD framework to study how rural tourism communities can successfully recover from the impact of the pandemic. It is found that the rapid recovery of rural tourism is the result of collective action. The core of establishing the collective action mechanism of rural tourism is consensus mechanism, co-construction mechanism and sharing mechanism. By studying the path and possibility of collective action of rural tourism communities, this paper explores the approach of multi-center governance of rural tourism communities to promote the imminent recovery of rural tourism.
The impact of support on employees' adaptive behavior: a moderated mediation model
Authors: Maden-Eyiusta Ceyda , Yalabik Zeynep Yesim , Nakiboglu Mehmet Ali Burak 
Published: August 2021

PurposeDrawing on the social exchange theory, this study focuses on the impact of perceived organizational support (POS) and perceived supervisor support (PSS) on employees' adaptive (selling) behavior in a personal selling context. As part of the support-adaptive behavior relationship, the authors also explore the mediating role of psychological empowerment and the moderating role of customer orientation (CO).Design/methodology/approachData were collected from 200 salespeople from the financial and pharmaceutical sectors in Turkey. Hypotheses were tested with hierarchical multiple regressions and hierarchical moderated regressions.FindingsSupported salespeople feel more empowered in their jobs and show adaptive (selling) behavior. Our results also show that the impact of support on adaptive selling behavior through empowerment is stronger for salespeople with low CO.Research limitations/implicationsThis study has two limitations: the generalizability of its findings and cross-sectional design. Still, it significantly contributes to support, empowerment and adaptive behavior literature.Practical implicationsBy creating a supportive work environment and by training their managers to improve their support skills, organizations boost their employees' adaptability. Both of these support practices motivate employees to use their discretion in sales situations. Organizations should also evaluate and manage their employees' level of CO by conducting company surveys and by increasing top management communication.Originality/valueThis study tests the mediating role of psychological empowerment on the relationship between POS, PSS and adaptive behavior in the understudied personal selling context. The authors also test the moderating role of CO in the proposed model.
Responsive stewardship and library advocacy in dystopian times: using information from the Civil Rights Movement and 1984 to strengthen libraries
Authors: Hunter Lily , Buchanan Sarah A. 
Published: August 2021

PurposeThe authors ask the question of how libraries can advocate for themselves and for those who most need the library during the pandemic, and evaluate how the authors adapt to a future of helping underserved and underrepresented populations in new ways after it subsides.Design/methodology/approachUsing data currently being provided by the Center for Disease Control and Prevention (CDC) and other sources, prior issue analyses dealing with library programs and advocacy, and lessons from a few dystopian novels, the authors lay out the political and social implications of the coronavirus on libraries now and in the future.FindingsBecause the coronavirus disease 2019 (COVID-19) pandemic shut down physical library buildings everywhere, forcing extremely slow re-openings and decimating library programs, conversation is building now on how libraries will overcome its massive blow. Underrepresented populations who most need library information (namely, the homeless, Native Americans, Black and Hispanic peoples among others) are suffering disproportionately from the pandemic and its aftereffects that are just beginning to reverberate.Originality/valueThis paper presents a viewpoint backed by lessons from American history, specifically the Civil Rights Movement, and the dystopian novel 1984 by George Orwell. Currently, the conversations around what will happen to libraries are limited, but will hopefully grow as libraries (and the rest of the world) attempt to move forward in an unprecedented situation.
The two‐component system RstAB regulates production of a polysaccharide capsule with a role in virulence in the marine pathogen Photobacterium damselae subsp. damselae

Published: August 2021

SummaryThe marine bacterium Photobacterium damselae subsp. damselae (Pdd) causes disease in marine animals and humans. Previous studies demonstrated that mutation of the two‐component system RstAB strongly impacts virulence of this pathogen, but the RstAB regulon has not been thoroughly elucidated. We here compared the transcriptomes of Pdd RM‐71 and ΔrstA and ΔrstB derivatives using RNA‐seq. In accordance with previous studies, RstAB positively regulated cytotoxins Dly, PhlyP and PhlyC. This analysis also demonstrated a positive regulation of outer membrane proteins, resistance against antimicrobials and potential virulence factors by this system. Remarkably, RstAB positively regulated two hitherto uncharacterised gene clusters involved in the synthesis of a polysaccharide capsule. Presence of a capsular layer in wild‐type cells was confirmed by transmission electron microscopy, whereas rstA and rstB mutants were non‐capsulated. Mutants for capsule synthesis genes, wza and wzc exhibited acapsular phenotypes, were impaired in resistance against the bactericidal action of fish serum and mucus, and were strongly impaired in virulence for fish, indicating a major role of capsule in virulence. Collectively, this study demonstrates that RstAB is a major positive regulator of key virulence factors including a polysaccharide capsule essential for full virulence in a pathogenic Photobacterium.
THE AESTHETICS OF GENTRIFICATION: Modern Art, Settler Colonialism, and Anti‐Colonialism in Washington, DC
Authors: Bockman Johanna 
Published: August 2021

AbstractIn 1988 a local homeowner in Washington, DC, commissioned a 30‐foot mural of an artwork by modernist painter Piet Mondrian on the side of a public housing building, along with several other similar murals across the street. Three months later all the residents of the public housing development were moved out. Later, the buildings were destroyed. Here I explore how these murals enabled the residents’ permanent displacement. Explaining this displacement and destruction by pointing to the federal Housing Opportunities for People Everywhere (HOPE) VI policy is completely insufficient. I argue for looking beyond the conventional actors in policy history to other actors, such as, but not limited to, aesthetics, art, artists and art purveyors. I examine Mondrian's years in Paris, during which he developed his abstract art and philosophy of spiritual evolution, white supremacy and total urban renewal. The homeowner brought Mondrian's art and philosophy to Washington, DC, at a time of an ideological shift towards global revanchism and gentrification. These specific murals reveal the settler colonial nature of gentrification in confrontation with anti‐colonial art and geographies. This study provides new insight into gentrification by illuminating the battles of multiple globalizations in cities and even on individual blocks.

AbstractBackgroundKawasaki disease (KD) is a syndrome that results in acute systemic vasculitis and is a major cause of acquired heart disease in developed countries. KD is diagnosed based on certain characteristic symptoms and echocardiogram results. It has been reported that abdominal ultrasound is of value in supporting the diagnosis of KD. Nevertheless, abdominal ultrasound is not a routine procedure in KD. Moreover, dilatation of the common bile duct (CBD) has been rarely reported in previous cases.Case presentationA 4‐year‐old boy presented with fever and markedly high transaminase level (aspartate aminotransferase, 5323 U/L; alanine aminotransferase, 1554 U/L). The patient was diagnosed as having KD based on characteristic symptoms and echocardiogram findings. Ultrasound revealed dilatation of the CBD as well as cervical lymphadenopathy resembling a cluster of grapes, thickening of the gallbladder wall, and increased periportal echogenicity throughout the liver parenchyma. The patient received initial treatment with intravenous immunoglobulin at day 4 of fever and second‐line treatment with intravenous immunoglobulin and prednisolone because of recurrent fever on day 6. Dilatation of the CBD was improved from 6.6 mm on day 4 to 3.1 mm on day 8. Although re‐dilatation was observed, it gradually diminished and normalized (4.3 mm on day 28, 4.0 mm on day 63, 3.3 mm on day 105, and 2.8 mm on day 182).ConclusionThis case highlights the usefulness of abdominal ultrasound and the importance of considering dilatation of the CBD as one of the complications of KD.
Corporate Governance Reforms and Cross‐Listings: International Evidence*
Authors: Liao Chih‐Hsien , Tsang Albert , Wang Kun Tracy , Zhu Nathan Zhenghang 
Published: August 2021

ABSTRACTIn this study, we examine whether a country's implementation of major corporate governance reforms affects firms' cross‐listing activities. Cross‐listing is important in overcoming international investment barriers and thus it is worth investigating whether enhanced corporate governance at the country level contributes to the integration of international capital markets. Using a difference‐in‐differences research design, we predict and find that following the implementation of corporate governance reforms in their home countries, firms are more likely to engage in cross‐listing activities and tend to cross‐list in host countries with stronger investor protection and more developed markets than those in countries with no reforms in the same period. The results from country‐level cross‐sectional tests indicate that this effect is greater for firms in home countries with weaker investor protection and less developed stock markets in the prereform period. The reforms also have a stronger effect on firms subject to less analyst following and greater external finance dependence. Finally, we find a stronger association between cross‐listing activities and institutional ownership after the reforms. Taken together, this study increases understanding of the trade‐off between cross‐border capital supply and demand. Our finding suggests that country‐level corporate governance plays an important role in facilitating the supply of cross‐border capital, which in turn incentivizes firms to cross‐list. Our study also offers policy implications for national stock exchanges and securities regulators by suggesting that countries without well‐developed capital markets should strengthen their corporate governance to improve firms' ability to raise external financing and attract cross‐border capital flows.
Clinical frailty scale: Inter‐rater reliability of retrospective scoring in emergency abdominal surgery

Published: August 2021

AbstractBackgroundFrailty is a complex syndrome shown to be an independent predictor of morbidity and mortality after surgery in older patients. Frailty scoring may, therefore, be important, for example, for pre‐operative risk assessment and prognosis estimation. The Clinical Frailty Scale (CFS) has been developed to help operationalize frailty in the individual patient. However, the inter‐rater reliability of retrospective CFS scoring through patient records by health care personnel is currently unknown in patients over 80 years of age undergoing emergency abdominal surgery.MethodsRetrospective review of electronic patient journal of 112 patients over 80 years of age undergoing emergency abdominal surgery between 2015 and 2016. Three researchers individually assigned each patient a CFS score. The inter‐rater reliability was assessed using Cohen's weighted kappa for the comparison of pairs of assessors, as well as Kendall's coefficient of concordance for the comparison of all three raters simultaneously.ResultsThe agreement across raters was strong, with Cohen's kappa values ranging between 0.74 and 0.85 and a Kendall's coefficient of concordance of 0.86.ConclusionsThe inter‐rater reliability of assigned CFS from patient journals seems acceptable. This could permit retrospective research utilizing CFS measures from several raters and across centers.

AbstractCancer stem cells (CSCs) are responsible for therapy resistance and share several properties with normal stem cells. Here, we show that brain‐expressed X‐linked gene 2 (BEX2), which is essential for dormant CSCs in cholangiocarcinoma, is highly expressed in human hepatocellular carcinoma (HCC) lesions compared with the adjacent normal lesions and that in 41 HCC cases the BEX2high expression group is correlated with a poor prognosis. BEX2 localizes to Ki67‐negative (nonproliferative) cancer cells in HCC tissues and is highly expressed in the dormant fraction of HCC cell lines. Knockdown of BEX2 attenuates CSC phenotypes, including sphere formation ability and aldefluor activity, and BEX2 overexpression enhances these phenotypes. Moreover, BEX2 knockdown increases cisplatin sensitivity, and BEX2 expression is induced by cisplatin treatment. Taken together, these data suggest that BEX2 induces dormant CSC properties and affects the prognosis of patients with HCC.

Published: August 2021

AbstractLong non–coding RNA AC020978 (lncRNA AC020978) is an oncogenic regulator of non–small cell lung cancer (NSCLC). However, the function of AC020978 in regulating NSCLC metastasis and the potential molecular mechanism remains largely unknown. In this study, we evaluated the expression levels of AC020978 in a series of NSCLC tissues using FISH assays and found that higher AC020978 expression levels were closely associated with metastasis and unfavorable prognosis. Functional studies showed that AC020978 promoted NSCLC migration and invasion both in vitro and in vivo. Further investigation demonstrated that AC020978 interacted with malate dehydrogenase 2 (MDH2) and maintained MDH2 stability. Knockdown of MDH2 weakened the facilitating effect on cell metastasis and 2‐hydroxyglutarate (2‐HG) metabolism in AC020978‐overexpressed NSCLC cells. RNA sequencing, bioinformatic analysis, and western blotting revealed that AC020978 was associated with the AKT signaling pathway. Taken together, our findings revealed that AC020978 might serve as a prognostic biomarker and activate the AKT pathway by stabilizing MDH2, leading to metastasis and progression of NSCLC.
Scalable Surface Reconstruction with Delaunay‐Graph Neural Networks

Published: August 2021

AbstractWe introduce a novel learning‐based, visibility‐aware, surface reconstruction method for large‐scale, defect‐laden point clouds. Our approach can cope with the scale and variety of point cloud defects encountered in real‐life Multi‐View Stereo (MVS) acquisitions. Our method relies on a 3D Delaunay tetrahedralization whose cells are classified as inside or outside the surface by a graph neural network and an energy model solvable with a graph cut. Our model, making use of both local geometric attributes and line‐of‐sight visibility information, is able to learn a visibility model from a small amount of synthetic training data and generalizes to real‐life acquisitions. Combining the efficiency of deep learning methods and the scalability of energy‐based models, our approach outperforms both learning and non learning‐based reconstruction algorithms on two publicly available reconstruction benchmarks.
Species richness and food‐web structure jointly drive community biomass and its temporal stability in fish communities

Published: August 2021

AbstractBiodiversity–ecosystem functioning and food‐web complexity–stability relationships are central to ecology. However, they remain largely untested in natural contexts. Here, we estimated the links among environmental conditions, richness, food‐web structure, annual biomass and its temporal stability using a standardised monitoring dataset of 99 stream fish communities spanning from 1995 to 2018. We first revealed that both richness and average trophic level are positively related to annual biomass, with effects of similar strength. Second, we found that community stability is fostered by mean trophic level, while contrary to expectation, it is decreased by species richness. Finally, we found that environmental conditions affect both biomass and its stability mainly via effects on richness and network structure. Strikingly, the effect of species richness on community stability was mediated by population stability rather than synchrony, which contrasts with results from single trophic communities. We discuss the hypothesis that it could be a characteristic of multi‐trophic communities.

AbstractBackground and purposeArterial clot localization affects collateral flow to ischemic brain in patients with acute ischemic stroke due to large vessel occlusion (AIS‐LVO). We determined the association between vessel occlusion locations, tissue‐level collaterals (TLC), and venous outflow (VO) profiles and their impact on good functional outcomes.MethodsWe conducted a multicenter retrospective cohort study of consecutive AIS‐LVO patients who underwent thrombectomy triage. Baseline computed tomographic angiography (CTA) was used to localize vessel occlusion, which was dichotomized into proximal vessel occlusion (PVO; internal carotid artery and proximal first segment of the middle cerebral artery [M1]) and distal vessel occlusion (DVO; distal M1 and M2), and to assess collateral scores. TLC were assessed on computed tomographic perfusion data using the hypoperfusion intensity ratio. VO was determined on baseline CTA by the cortical vein opacification score. Primary outcomes were favorable VO and TLC; secondary outcome was the modified Rankin Scale after 90 days.ResultsA total of 649 patients met inclusion criteria. Of these, 376 patients (58%) had a PVO and 273 patients (42%) had a DVO. Multivariate ordinal logistic regression showed that DVO predicted favorable TLC (odds ratio [OR] = 1.77, 95% confidence interval [CI] = 1.24–2.52, p = 0.002) and favorable VO (OR = 7.2, 95% CI = 5.2–11.9, p < 0.001). DVO (OR = 3.4, 95% CI = 2.1–5.6, p < 0.001), favorable VO (OR = 6.4, 95% CI = 3.8–10.6, p < 0.001), and favorable TLC (OR = 3.2, 95% CI = 2–5.3, p < 0.001), but not CTA collaterals (OR = 1.07, 95% CI = 0.60–1.91, p = 0.813), were predictors of good functional outcome.ConclusionsDVO in AIS‐LVO patients correlates with favorable TLC and VO profiles, which are associated with good functional outcome.
Probing strain rate effect on the creep–fatigue fracture mechanism of 9%Cr steel‐welded joint via nanoindentation characterization

Published: August 2021

AbstractThe strain rate‐related creep–fatigue (CF) interactions on the long‐term service damage of 9%Cr steel‐welded joint were investigated at low‐strain amplitude (0.2%). Initially, the average CF life gradually increased from 1,103 to 2,185 cycles as strain rate increased from 0.0001 to 0.002 s−1, and then it slowly decreased from 2,185 to 1,503 cycles as continuously increase the strain rate from 0.002 to 0.005 s−1. By increasing strain rates, the microscale observation indicates the CF fracture location could be shifted from the fine‐grained heat‐affected zone (FGHAZ) to the base metal (BM) region. Meanwhile, the local microscale mechanical properties including hardness, elastic modulus, creep resistance, and strain rate sensitivity on the fractured specimens with a series of strain rates were detected by instrumental nanoindentation. With increasing CF strain rates, the nanoindentation hardness and creep resistance evidently dropped. Based on the characteristics of microstructural evolution and the variation in local mechanical properties, strain rate effects of CF interaction on fracture mechanism of the welds were systematically discussed.
