Internet penetration and international travel and tourism expenditure: The role of foreign exchange control

The total amount of digital travel sales worldwide increases significantly every year, yet previous studies on outbound tourism expenditures have scarcely discussed the role of foreign exchange control (Fxc) as a barrier to e-internationalization. In the era of e-commerce, residents of more than 40 economies are not allowed to buy or pay for foreign products by the Internet. This article, with data from 95 economies in the period 2012–2017, concludes that Internet penetration development increases international tourism expenditure. On the other hand, the control of foreign exchange decreases the relationship between internet penetration and tourism expenditure. Therefore, Fxc is clearly a barrier to electronic internationalization and tourism expenditure.
Extracting and Analyzing Inorganic Material Synthesis Procedures in the Literature

Materials informatics requires large-scale collection and analysis of material synthesis procedures described in the literature for designing materials using computational methods. However, existing studies have not performed the paragraph-level analysis of the procedures. Moreover, since most of the synthesis procedures are described in natural language in articles and technical documents, it is necessary to structure them in a format that can be handled by computers through information extraction. Therefore, in this study, we construct a pipeline system that extracts synthesis procedures from text in the form of a flow graph and analyzes each procedure as a flow graph rather than a set of processes. The extraction system extracts entities by the deep learning model and relations between entities by the rule-based extractor from all paragraphs in the literature and selects procedures that include valid structures of entities and relations. Our evaluation of a benchmark dataset gave micro-averaged F-scores of 0.807, 0.830, and 0.609 for the entity extractor, relation extractor, and pipeline extractor, respectively. We applied this system to a large amount of literature and extracted approximately 90,000 flow graphs (procedures) containing approximately 4 million entities and 3 million relations. We performed several analyses, including taking statistics of the extracted graphs and checking frequent subgraphs for the extracted graphs. Commonly used methods in materials science were confirmed from our analyses; for example, ethanol is often dried by heating at 60 °C, and less-reactive noble gases are rarely included in the products. As a result, we experimentally confirmed that the extracted procedures were reasonable.
Psychological distance as a working tool for managers

This article presents a synthesis of research that has drawn on the concept of psychological distance around questions related to prosocial consumer behavior, digitalization of consumption, and marketing practices. Our study is based on a meta-synthesis of 584 articles from psychology and marketing journals. It consolidates and validates the knowledge of the concept of psychological distance in these different marketing themes. It also shows how psychological distance can be used by managers to improve consumer responses. Managers can act directly on distance by reducing or increasing it to take advantage of the benefits of psychological proximity or remoteness. They can also adjust the variables of the marketing mix according to the psychological distance experienced by the consumer in order to make information processing more fluent and, ultimately, to improve the consumer’s responses.
Comparisons of particulate-bound mercury (PBM) compositions in soil and vegetation at a traffic site

ABSTRACT This investigation analyzes the particulate-bound mercury (PBM) compositions in soil and vegetation at a traffic sampling site in Taichung, Taiwan, during a sampling period from October to December, 2015. A direct mercury analyzer (DMA-80) was used to measure the particulate-bound mercury (PBM). A T-test was conducted to determine the mean differences between the PBM composition in soil and that in vegetation at the site. The results indicate that 1) the mean particulate-bound mercury compositions in soil and vegetation were the lowest in November, when the (mean OR average) wind speed was the highest (4.1 m/s); 2) Particulate-bound mercury compositions (PBM) in both soil and vegetation correlated weakly with temperature, humidity and wind speed; 3) T-test statistical results denoted that the PBM compositions did not significantly differ between soil and vegetation in the three-month sampling period.
Gamification narrative design as a predictor for mobile fitness app user persistent usage intentions: a goal priming perspective

ABSTRACT Many users fail to stick to the use of mobile fitness apps. As a key element of gamification mechanisms, effective gamification narrative design has the potential to draw the users in and motivates them to develop stronger motivations to achieve their real-world goals and higher persistent usage intentions of the mobile fitness App. Underpinned by goal priming theory, we conducted two controlled experiments, surrounding core aspects of gamification narrative design, namely narrative path agility and narrative target clarity. The results, which revealed that different forms of gamification narrative design impact users’ real-world fitness purpose and persistent usage intentions through different strategies, provide interesting implications for both theory and practice.
Heavy Metal Tolerance and Removal Capacity of Trichoderma species Isolated from Mine Tailings in Itogon, Benguet

Waste from mining industries contains various heavy metals that can pollute the environment. Bioremediation using efficient fungi can help in eliminating these heavy metal contaminants. This study focused on the isolation, identification, and characterization of heavy metal-resistant fungi from mine tailings in Itogon, Benguet. Isolation of fungi was done by serial dilution and spread plate techniques on potato dextrose agar (PDA) with an individual heavy metal, i.e. chromium (Cr), copper (Cu), lead (Pb), zinc (Zn), and nickel (Ni). Of the 29 fungal isolates, four species were selected and molecularly identified as Trichoderma virens, T. harzianum, T. saturnisporum, and T. gamsii. Growth tolerance on PDA with increasing concentrations (200-1000 ppm) of an individual heavy metal indicated the following trend: T. virens > T. harzianum > T. gamsii > T. saturnisporum. Growth test indicates that all Trichoderma isolates can tolerate high levels of Cr and Pb, however tolerance to Cu, Zn, and Ni was species specific. Shakeflask culture using T. virens showed high lead removal (91-96%) over broad pH range while and at neutral pH, T. virens had 70% and 63% reductions for Cu and Cr, respectively. Results of this study highlights the potential of Trichoderma isolates for biological wastewater treatment in mining industries.
Synthesis of holmium orthoferrite nanoparticles by the co-precipitation method at high temperature

Holmium orthoferrite HoFeO3 nanoparticles were synthesized by a simple co-precipitation method via the hydrolysis of Ho (III) and Fe (III) cations in boiling water with 5% aqueous ammonia solution. After annealing the precipitate at 750 and 850 °C for 1 hour, the single-phase HoFeO3 product formed with particle size < 50 nm. The synthesized nanopowders are paramagnetic materials with remanent magnetization Mr < 0.01 emu·g-1, the coercive force Hc = 20÷21 Oe, and magnetization Ms ~ 2.73 emu·g-1 at 300 K in a maximum field of 16,000 Oe.
INS/GPS Sensor Fusion based on Adaptive Fuzzy EKF with Sensitivity to Disturbances

Abbas Chatraei, Department of Electrical Engineering, Najafabad Branch, Islamic Azad University, Najafabad, Iran. Email: abbas.chatraei@pel.iaun. ac.ir Abstract The estimation accuracy of the inertial navigation system integrated with the global positioning system (GPS) through multiple kinds of Kalman filters (KFs) has been widely considered. Since the classical KFs could not overcome environmental disturbances and noises, adaptive and robust structures are utilised in sensor fusion techniques. Here, different types of adaptive structures have been assumed. The fuzzy inference system benefits the adaption of the measurement covariance matrix, a scale factor employed to tune the process covariance matrix and the Chi‐square algorithm to detect and bound the disturbances. The estimation accuracy and robustness of the adaptive fuzzy extended Kalman filter (AFEKF) are compared with the unscented Kalman filter (UKF) and extended Kalman filter (EKF) structure in various scenarios involving position, velocity, attitude, accelerometer and gyroscope bias estimation errors. Likewise, in order to evaluate the AFEKF approach practically, an embedded electronic board is designed involving an ARM microcontroller, an inertial measurement unit sensor, and a GPS receiver, which was installed on a land vehicle. The results demonstrated the superiority of the AFEKF over the UKF and EKF in the case of lower estimation error and higher robustness against disturbances and outliers.
Lost in ‘translation’? A set of writing workshops improves Molecular Medicine Honours students’ perceptions of their scientific report writing skills

ABSTRACT Undergraduate science degrees in South Africa seldom offer explicit courses focussing on improving the disciplinary writing skills required for effectively communicating scientific research. Similarly, most students entering the ‘Honours’ degree in Molecular Medicine at a South African university have not commonly been afforded opportunities to develop appropriate scientific writing and thinking skills. Aspiring to improve writing abilities, in 2017 we introduced a set of writing workshops involving iterative writing activities of scientific report sections with dialogic feedback from the facilitator. This study aimed to interrogate whether the workshops achieved the intended outcomes by conducting a post-course survey to ascertain the perceptions of the Molecular Medicine students. We also compared the grades awarded for the scientific reports in years before and since the implementation of the workshops. Students highlighted numerous ways that the workshops had improved their ability to write sections of a scientific report, while the average grade for the scientific report also increased significantly since the introduction of the workshops. These results reveal that the structure and activities of our workshops can teach scientific writing skills to early-postgraduate level bioscience students with relatively little disruption to the existing curriculum and help inform the format of future writing workshops.
Influence of the electron buffer layer on the photovoltaic performance of planar Sb2(SxSe1‐x)3 solar cells

Appropriate selection of electron buffer layer and understanding its impact on the photo‐generated charge transfer dynamics at the interfaces are critical to enhance the efficiency of solar cells. By optimizing a multilayer electron buffer composed of CdS thin film deposited on TiO2 compact layer, we obtained a power conversion efficiency (PCE) of 5.47% for a planar solar cell of Sb2(SxSe1‐x)3 absorber. The PCE was significantly enhanced in the photovoltaic parameters of planar solar cells fabricated with single‐layer configuration: for example, PCE of 3.99% and 0.79% were obtained when either CdS or TiO2, respectively, were used. Surface photovoltage spectroscopy, transient photovoltage, and electrochemical impedance spectroscopy analyses indicated that the PCE improvement can be ascribed to a combination of 2 factors: (i) better separation and transfer of the photo‐excited free charge, provided by the beneficial energy level alignment between TiO2 and CdS layers, and (ii) sulfur passivation upon incorporation of CdS in a multilayer configuration causing a reduction in the trap states at the interface with Sb2(SxSe1‐x)3.
Frequency of Obesity among Gastroesophageal Reflux Disease Patients

Objective: Gastroesophageal reflux disease (GERD) prevalence ranges from 24% to 35% in Pakistani population. Studies have demonstrated GERD frequency is directly proportional to increasing weight. Thus, the frequency of obesity among gastro esophageal reflux disease patients was determined. Methodology: This cross-sectional study was conducted on outpatients with GERD visiting Department of Hepatogastroenterology, Sindh Institute of Urology and Transplantation, Karachi; from December 2017 to June 2018. Clinical and demographic parameters of study population were recorded. Body mass index (BMI) more than 27 was labeled as obese. Patients with history of ischemic heart disease, pregnancy, ascites and/or Patients on NSAIDS, bisphosphonates or steroids were excluded. Results: One hundred and fifty patients with mean age of 43.3±11.5 years were included in study. Eighty-seven patients (63.3%) had age more than 40 years. Majority of study population were males 95 (63.3%). Mean height and weight of study population were 163.09±9.56 cm and 72.92±15.13 kg, respectively. Mean BMI were 27.55±6.02 in which 71 (47.3%) were obese i.e., BMI >27. Majority were Urdu speaking i.e., 57 (38%) followed by Sindhi 31 (20%) Diabetes mellitus was documented in 22 (14.7%) and hypertension in 16 (10.7%) patients. Statistically significant association of GERD was seen in obese females (p-value: 0.018) Conclusion: Increase frequency of obesity is significantly associated with GERD. More proportion of obese females has GERD. Keywords: Gastro esophageal reflux disease; Body mass index; Weight; height
Measurement of Epicardial Fat Using Non-contrast Routine Chest-CT: A Consideration of Threshold Adjusting for Fatty Attenuation

Background：Role of epicardial fat (EF) had expended from a marker of cardiovascular risk to indicators of several systemic physiological effects and needed to be measured in more scenarios. The present study aimed to determine whether the EF volume (EFV) and mean attenuation (EFA) measured on non-contrast routine chest-CT (RCCT) could be more consistent with that on coronary CT angiography (CCTA) by adjusting the threshold of fatty attenuation. Methods: Totally 83 subjects simultaneously underwent CCTA and RCCT were enrolled. EFV and EFA were quantified on CCTA using threshold of (N30) (-190HU, -30HU) as reference, and also measured on RCCT using threshold of N30, N40 (-190HU, -40HU), N45 (-190HU, -45HU) respectively. Correlation and agreement of EF metrics between two models and differences between groups with coronary plaque (Plaque (+)) and without plaque (Plaque (-)) were analyzed. Results: EFV and EFA from RCCT using N30, N40 and N45 correlated well with reference (EFV: r2=0.974, 0.976, 0.972, P<0.001; EFA: r2=0.516, 0.500, 0.477, P<0.001). Threshold adjusting was able to reduce the mean difference, while increase the difference of EFA. Data measured on CCTA and RCCT both demonstrated the significantly larger EFV of Plaque (+) group than Plaque (-) group (P<0.05). The significantly difference of EFA was only shown on RCCT using N30 (Plaque (+) vs (-): -80±4.4HU vs-78±4HU, P=0.030). Conclusion: The consistency of EFV measured on RCCT could be improved through adjustment of attenuation threshold. The EFA assessment may have additional information relating to underlying pathophysiological status.
Rapid hydroponic screening for molybdenum tolerance in rice through morphological and biochemical analysis

High yielding varieties of rice (Oryza sativa) cultivars were tested for their tolerance to different levels of molybdenum (Mo) (0.1 μM – control, 0.2, 0.4, 0.8 and 1.6 μM) in nutrient solution at pH 6.8. Seeds of rice were germinated and grown in presence of molybdenum under controlled environmental conditions. Standard growth parameters such as root length, shoot length, root/shoot dry biomass and root/shoot tolerance index were tested as markers of molybdenum toxicity. Measurements as early as 48 hours after the germination did not yield consistent results. However, root measurement on 3, 6 and 9 day after root emergence showed significant differences among cultivars of rice. Rice cultivars Annapurna, Kusuma, Deepa and Vaghari developed better root system while, Paridhan-1, Pusa-2-21 and Ratna showed poor growth of the roots in presence (0.8 μM) of molybdenum. The root tolerance index (RTI) and the shoot tolerance index (STI) in Annapurna, Kusuma and Deepa in rice were high indicating their tolerance to molybdenum; Paridhan-1 and Ratna, however, showed low RTI and STI. Based on the growth parameters, twenty cultivars of rice were ranked in respect of their tolerance to molybdenum: Annapurrna > Deepa > Kusuma > Vaghari > Hamsa > Vikram > Bharati > Paridhan-2 > Aswathi > Subhadra > Sankar > Sakti > Nilgiri > Rudra > Hema > Pragati > Pusa-2-21 > Ratna > Paridhan-1, respectively. Molybdenum toxicity was correlated with increased peroxidase and catalase activity in different cultivars of rice. This method can be employed for quick screening of rice cultivars for molybdenum tolerance in breeding programmes.
A Two-Step PCR Protocol Enabling Flexible Primer Choice and High Sequencing Yield for Illumina MiSeq Meta-Barcoding

High-throughput amplicon sequencing that primarily targets the 16S ribosomal DNA (rDNA) (for bacteria and archaea) and the Internal Transcribed Spacer rDNA (for fungi) have facilitated microbial community discovery across diverse environments. A three-step PCR that utilizes flexible primer choices to construct the library for Illumina amplicon sequencing has been applied to several studies in forest and agricultural systems. The three-step PCR protocol, while producing high-quality reads, often yields a large number (up to 46%) of reads that are unable to be assigned to a specific sample according to its barcode. Here, we improve this technique through an optimized two-step PCR protocol. We tested and compared the improved two-step PCR meta-barcoding protocol against the three-step PCR protocol using four different primer pairs (fungal ITS: ITS1F-ITS2 and ITS1F-ITS4, and bacterial 16S: 515F-806R and 341F-806R). We demonstrate that the sequence quantity and recovery rate were significantly improved with the two-step PCR approach (fourfold more read counts per sample; determined reads ≈90% per run) while retaining high read quality (Q30 > 80%). Given that synthetic barcodes are incorporated independently from any specific primers, this two-step PCR protocol can be broadly adapted to different genomic regions and organisms of scientific interest.
Feeling Lonely Increases Interest in Previously Owned Products

Consumption of used products has the potential to symbolically connect present and previous users of these products, something that may appeal to lonely consumers. Accordingly, across seven studies, feeling lonely increased consumers’ preference for previously owned products. Specifically, the authors found that the proportion of lone shoppers was higher in a used versus a regular bookstore, lone individuals (vs. those sitting in pairs) were more likely to select a used over a new product, people without (vs. with) a date on Valentine’s Day expressed stronger preference for used products, and individual differences in loneliness during the COVID-19 pandemic predicted interest in used products. Other studies documented that the desire to symbolically connect underlies the effect of loneliness on consumption. At a time when loneliness is on the rise, the authors discuss implications for the marketing of used products and how loneliness might motivate consumers to reduce waste.
Highly active, stable oxidized platinum clusters as electrocatalysts for the hydrogen evolution reaction

In the present work, we synthesized and characterized an electrocatalyst consisting of sub-nanometric Pt clusters uniformly dispersed on a TiO2 support. X-ray photoelectron spectra (XPS) and X-ray adsorption fine structure (XAFS) data demonstrate that these sub-nanometric Pt clusters are in a highly oxidized state and possess two localized Pt–O coordination structures. The Pt–O bonds between the oxidized Pt clusters and the TiO2 give rise to a strong metal–support interaction (SMSI). When applied to the hydrogen evolution reaction (HER), this catalyst exhibits significantly enhanced catalytic activity (increased by a factor of up to 8.4) and enhanced stability compared with the state-of-the-art commercial Pt/C catalysts. Particularly, the additional XPS and XAFS characterizations of the catalyst after long-term electrolysis demonstrate the absence of metallic Pt species, confirming that the catalytic active site comes from the oxidized Pt clusters rather than from the the metallic Pt species. This improved performance is considered to be induced by the unique electronic structure of the oxidized Pt clusters and by the SMSI. Based on the results of density functional theory calculations, the 5d orbital of the oxidized Pt cluster atoms appears to hybridize with the H 1s orbital to form weak Pt–H valence bonds, leading to a ΔG (relative free energy) value of approximately zero eV for H* absorption. This effect explains the mechanism responsible for the excellent catalytic activity of these oxidized Pt clusters for the HER. This work therefore provides important insights into the role of oxidized Pt clusters as an HER electrocatalyst. The evident stabilization of the oxidized Pt clusters on TiO2 supports via the charge-transfer mechanism provides a useful approach for improving the durability of electrocatalysts that may be applicable to other noble metal/support systems.
