Social distance is an important tool for evaluating the degree of intimacy between individuals that has been applied in various disciplines. However, while increasing attention has been paid to this topic, little effort has been invested in understanding the construct of social distance between tourism community residents. The purpose of this study was to develop a scale that would assist in understanding and evaluating the social distance between tourism community residents. First, focus group interviews,...

This white paper uses recent public data to identify what we can know systematically about how the COVID-19 pandemic is currently affecting the large, research-intensive universities that represent the core of the US-ARE. It uses those, admittedly preliminary and partial, findings to extrapolate about possible long-term effects of decisions that academic leaders, state and federal policy makers are taking right now. The descriptive story presented here isn't determinative, but it suggests that the pandemic poses...

A dynamic treatment regime (DTR) is a sequence of decision rules that adapt to the time-varying states of an individual. Black-box learning methods have shown great potential in predicting the optimal treatments; however, the resulting DTRs lack interpretability, which is of paramount importance for medical experts to understand and implement. We present a stochastic tree-based reinforcement learning (ST-RL) method for estimating optimal DTRs in a multistage multitreatment setting with data from either randomized trials or...

Patients with depression have a high prevalence of developing dyslipidemia. In this study, we aim to investigate the difference of serum lipids, including total cholesterol (TCH), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and triglycerides (TG), between the depressed patients and healthy controls. Sex differences in lipids and their psychological correlations were also included. The study included 56 healthy controls (males/females = 26/30) and 110 first-diagnosed drug-naïve outpatients (males/females = 35/75). A total of...

Virulence attenuation frequently occurs in in vitro culturing of pathogenic microbes. In this study, we investigated the total putative long noncoding RNAs (lncRNAs) in an aphid-obligate pathogen, Conidiobolus obscurus, and screened the differentially expressed (DE) lncRNAs and protein-coding genes involved in the virulence decline. The virulence was significantly attenuated after eight subculturing events, in which the median lethal concentration of the conidia ejected from mycelial mats relative to the bamboo aphid, Takecallis taiwanus, increased from...

Using a relational two-stage network data envelopment analysis (DEA) model considering undesirable outputs, this paper evaluates both the process and system performances of industrial environmental governance in China’s 30 provincial-level regions during 1998–2015. Furthermore, this is the first study to apply the spatial econometric models with a geographical distance matrix to investigate the local and spatial spillover effects of environmental regulations on heterogeneous environmental governance performance (i.e. clean production and end-of-pipe treatment performances). The results...

It is commonly believed that the response of the price of corn ethanol (and hence of the price of corn) to shifts in biofuel policies operates in part through market expectations and shifts in storage demand, yet to date it has proved difficult to measure these expectations and to empirically evaluate this view. We utilize a recently proposed methodology to estimate the market’s expectations of the prices of ethanol, unfinished motor gasoline and crude oil...

Numerous methods based on square rasters have been proposed for polygon generalization. However, these methods ignore the inconsistent distance measurement among neighborhoods of squares, which may result in an imbalanced generalization in different directions. As an alternative raster, a hexagon has consistent connectivity and isotropic neighborhoods. This study proposed a hexagon-based method for polygon generalization using morphological operators. First, we defined three generalization operators: aggregation, elimination, and line simplification, based on hexagonal morphological operations. We...

Collection, preservation, and shipment of histological specimens in low-resource settings is challenging. We present a novel method that achieved excellent preservation of placental specimens from rural Mali by using formalin fixation, ethanol dehydration, and long-term storage in a solar-powered freezer. Sample preservation success was 92%, permitting evaluation of current and past malaria infection, anemia, placental maturity, and inflammation. Using RNAscope® hybridization we were able to visualize cell-specific gene expression patterns in the formalin-fixed paraffin-embedded (FFPE)...

The aim of the study was to determine molecular genetic and clinical characterization of acute myeloid leukemia (AML) with trisomy 8 as the sole chromosome abnormality, a recurrent but rare chromosomal abnormality in AML. Interphase fluorescence in situ hybridization, reverse transcriptase-quantitative polymerase chain reaction for gene rearrangement and next-generation sequencing (NGS) were performed on sole trisomy 8 AML patients. A total of 35 AML patients with trisomy 8 as the sole chromosome abnormality were screened....

Identifying optimal treatments for patients living with rare diseases is challenging due to the small numbers of individuals affected. One design used to address this challenge is known as the small n, sequential, multiple assignment, randomized trial (snSMART). To investigate the efficacy of an active drug measured by a continuous outcome tested at a low and high dose compared to placebo, we propose a new two-stage snSMART design. In stage 1, patients are randomized to...

In this study, blueberry fruits (Vaccinium corymbosum cv. ‘Bluerain’) were sprayed with different concentrations (0.25, 0.5, 0.75, and 1 mg/L) of exogenous 24-epibrassionolide (EBR) after harvest and kept at 18°C and relative humidity of 90∼95% for 8 d. By observing the decay incidence and firmness changes, the optimal treatment concentration (0.75 mg/L) was screened, and then the effects of 0.75 mg/L EBR treatment on fruit quality and antioxidant activities were further explored. The results showed...

The coordination behaviors of asymmetric quinoline-decorated half-salamo-type ligand HL1 with Cu(NO3)2·3H2O and Cu(OAc)2·H2O were studied. Two Cu(II) complexes, [Cu(L1)(NO3)]·CH3CH2OH (1) and [Cu2(L2)2] (2), were isolated and characterized by X-ray crystallography, FTIR, UV–vis, and fluorescence spectroscopies. Structural analyses showed that 1 is a mononuclear species, whereas 2 is a binuclear entity. Spontaneous cleavage along the oxime N-O bond close to quinoline ring of the ligand HL1 occurred upon reaction with Cu(OAc)2·H2O, yielding an unexpected complex 2....
