The impact of headline features on the attraction of online financial articles

Purpose This study aims to investigate whether and to what extent the characteristics of headlines impact the attraction of online financial articles by using data collected from WeChat, a popular social app in China. Design/methodology/approach By integrating the methods of econometric and text mining, this study analyzed the content of 113,917 headlines published by 126 official accounts from the day account being created to May 12, 2016. Hierarchical regression was used to investigate the effects of headline features, account ownership type and stock market volatility on the attraction of online financial articles. Findings The empirical results show that sentiment, length, domain specificity and language intensity in a headline are significantly associated with the attraction of an online financial article. In addition, the relative and moderating roles of stock market volatility and account ownership type were also explored, showing significant moderating effects on the relationship between sentiment and online article attraction. Research limitations/implications This study had several limitations. First, the sample data for this research were collected from one social media platform. While WeChat is the most popular social media application in China, it is just one of the many social media applications that can be used to publish online financial articles, and it differs from other social media applications greatly. This makes it hard to generalize the conclusions of the study. Future studies could compare the different features of headlines and their effects on the attraction of financial articles on different platforms. Second, in mining the characteristics of headline, this study only analyzed the influence of the sentiment, domain specificity, length and language intensity of the headline on article attraction. In future studies, in-depth analysis of the headline content could be conducted, such as the similarity between the body text and the headline, the theme and the sense of humor. However, the authors believe that these limitations do not have major negative implications for the results and contributions of this study. Practical implications From a practical perspective, this work could help official WeChat accounts to write better headlines for the articles they publish to attract more readers and fans and thus improve the value of their accounts, which would enable them to maximize the tangible benefits through differential pricing on advertisement placement. Originality/value The contributions of this study are as follows. First, the paper explored how headline sentiment influences article attraction and found that positive sentiment is negatively related to article attraction, while negative sentiment is positively related to article attraction. In addition, there is an inverted U-shaped relationship between the extent of negative sentiment and article attraction. Second, the paper investigates how headline domain specificity affects article attraction and there is an inverted U-shaped relationship between headline domain specificity and article attraction. Third, to the best of the authors’ knowledge, this is the first large-scale case study that explores the association between stock market volatility and the attraction of an online financial article.

Preparation of foamed aluminum and its application in China

As a new structural material combined with functional characteristics, aluminum foam possesses low density, high specific surface area and stiffness, good sound and energy absorption, as well as excellent electromagnetic shielding. Among the preparation ways which can be used to fabricate aluminum foam, the methods, such as direct foaming in aluminum melt, melt foaming by gas injection, powder metallurgy route and casting around space holder materials, may be the main ones. The R & D of the methods above in China is discussed in this paper. Aluminum foams have been exploited in road noise barrier, buildings, rail transit vehicles, aerospace and bridge protection in China nowadays. The applications of aluminum foams obtained by some methods are also emphatically described. It is speculated that the application fields and amount of the aluminum foams may be increased in the future along with the further development of Chinese economy.

Enterococci may not present the pollution of most enteric pathogenic bacteria in recreational seawaters of Xinghai bathing Beach, China

Abstract Many un-developed countries select fecal indicator bacteria (FIB) based on the recommendation of the U.S. EPA, or WHO criteria. To prove its applicability in China, FIB, human markers, and 15 typical bacterial pathogens were assessed using both culture dependent and independent methods (PCR, gene chip, and quantitative PCR) in Xinghai bathing beach of China. In most cases, enterococcus can indicate the pollution phenomenon of the main pathogenic bacteria (Staphylococcus aureus, Aeromonas caviae and Streptococcus faecalis), while only correlated with human Bacteroides and Staphylococcus aureus, which all suggested that the use of enterococci may not accurately assess the risk of most enteric pathogenic bacteria. Therefore, periodic surveying of human specific Bacteroides is strongly recommended, the monitoring of the most prevalent enteric pathogen, Aeromonas caviae, and the autochthonous pathogen, Vibrio parahaemolyticus should also be taken into consideration in the routine monitoring to protect bathers health.

Sampling and analysis of airborne ammonia in workplaces of China.

ObjectivesWith the increasing demand for the detection of occupational hazard factors in workplaces, the national standard determination method for ammonia (sampling with absorbing solution‐analysis with Nessler reagent spectrophotometry) in the air of workplace presents many drawbacks during application in China. This review summarized the improvement and the alternate methods of the current sampling and analysis procedures for ammonia, aiming to provide reference to establish an appropriate method for the determination of ammonia in workplace air.MethodsScientific publications in English and Chinese and the standard methods of the Deutsche Forschungsgemeinschaft (DFG) in Germany, the National Institute for Occupational Safety and Health (NIOSH) and Occupational Safety and Health Administration (OSHA) in the United States, and Ministry of Health in China for airborne ammonia collection and analysis in the workplace were reviewed.ResultsThe measures to improve the current sampling and analysis procedures for ammonia in China were firstly summarized. For sampling, the decrease of absorbing solution concentration and the methanesulfonic acid solution as the alternate sampling solution were suggested. For analysis, the anti‐interference measures and the optimum reaction condition between ammonia and Nessler reagent were discussed. The alternate methods including sampling conducted using solid sorbent tubes and analysis performed by ion chromatography were then considered for the determination of ammonia.ConclusionsThe methods—sampling with acid‐treated solid sorbent tubes and analysis with ion chromatography—were more suitable for the determination of ammonia in workplace air. However, some details about ammonia sampling and analysis still need further investigation.

Development and validation of thermo-mechanical analysis code of metallic fuel under steady-state conditions in LMFR

Thermal characteristics and mechanical analysis are particularly essential in the performance and safety analysis of metallic fuel for Liquid Metal Fast Reactor (LMFR). Therefore, the development of advanced thermo-mechanical analysis code is significant for the safety design of metallic fuels. In order to meet the future demand for metallic fuel application in China, the FRAC code was developed to analyze the metallic fuel performance during steady-state conditions. The code was benchmarked against the open-literature EBR-II experimental database. In comparison with the experimental data given, the code calculated Zr mole fraction, fuel temperature distribution, fission gas release and clad strain distribution are in good agreement with the data, which indicates that the code is reliable and can be applied into safety analysis of metal fuel design in China. The overall code assessment shows that the prediction error is within acceptable range.

What Can Be Learned from Billions of Invoices? The Construction and Application of China’s Multiregional Input-Output Table Based on Big Data from the Value-Added Tax

ABSTRACT The big data on the value-added tax (VAT), which links upstream production and downstream consumption, can serve as a key basis for a structured macroeconomic analysis. This paper discusses the construction and aggregation method of the transaction matrix between enterprises based on this data and develops a multiregional input-output (MRIO) table. The intraregional structure of this table is consistent with the IO table in China’s national statistics and includes more detail on the domestic value chain. We use big data on the VAT in creating an analytical tool to track profit shifting and tax avoidance. Therefore, this new MRIO table can coordinate consumption-based measures with the “destination principle” in international VAT statistics.

What happens after young adults’ “friending” of parents? A qualitative study about mediated family communication and privacy management in China

The existing literature on “friending” parents on mobile social media has focused on the momentary decision of accepting the “friending” requests. In addition, a major body of research on privacy management online focuses on predicting privacy protection behaviors based on samples primarily from the United States. This in-depth qualitative study employs focus groups to explore how Chinese young people interact with their parents after accepting them as friends on WeChat, a popular mobile social application in China. Many participants reported privacy turbulence due to parental interference with young adults’ expression of their own values and behaviors on WeChat, which reflects the deep conflict between the collectivistic culture (the parental generation) and the individualistic culture (young adults) in contemporary Chinese society. This study also finds that a family’s offline communication is generally parallel to its online communication on mobile social media after young people’s friending of parents.

Design, Synthesis and Biological Evaluation of Diosgenin-Amino Acid Derivatives with Dual Functions of Neuroprotection and Angiogenesis.

Diosgenin, a natural product with steroidal structure, has a wide range of clinical applications in China. It also shows great potential in the treatment of blood clots and nerve damage. To enhance the bioavailability as well as efficacy of diosgenin, eighteen diosgenin-amino acid derivatives were designed and synthesized. The neuroprotective effects of these compounds were evaluated by SH-SY5Y cell line and the biosafety was evaluated by H9c2 cell line. The results displayed that part of the derivatives’ activities (EC50 < 20 μM) were higher than positive control edaravone (EC50 = 21.60 ± 3.04 μM), among which, DG-15 (EC50 = 6.86 ± 0.69 μM) exhibited the best neuroprotection. Meanwhile, biosafety evaluation showed that DG-15 had no cytotoxicity on H9c2 cell lines. Interestingly, combined neuroprotective and cytotoxic results, part of the derivatives without their protecting group were superior to compounds with protecting group. Subsequently, Giemsa staining and DAPI (4′,6-diamidino-2-phenylindole) staining indicated that DG-15 had a protective effect on damaged SH-SY5Y cells by reducing apoptosis. Moreover, DG-15 showed a higher role in promoting angiogenesis at high concentrations (4 mg/mL) on the chorioallantoic membrane model. This finding displayed that DG-15 had dual functions of neuroprotection and angiogenesis, which provided further insight into designing agent for the application in treatment of ischemic stroke.

"Mobile Health" for the Management of Spondyloarthritis and Its Application in China.

Spondyloarthritis (SpA) is a group of inflammatory diseases characterized by inflammation in the spine, peripheral joints, and entheses that usually start at the prime of one's life and lead to impaired physical function and reduced quality of life. Ankylosing spondylitis (AS) is prototype of SpA. This article reviews the opportunities and challenges of using mobile health (mHealth) in managing SpA, and report some of our experiences using a mHealth solution for management of SpA patients and performing related research in China. The recent rapid development of mobile communications and the common use of intelligent electronic devices have led to the increasing application of mHealth for chronic disease management by healthcare providers and patients alike. This is a promising new technology that can help mitigate limitations in time and space for patient management, promote easier communication between patients and their healthcare providers, reduce medical expenses, and optimize medical services. We have developed a smartphone-based mHealth SpA management system (SpAMS) that also helps the patients to monitor, manage, and share information on their disease with their physician at regular intervals. There is a shift from a paternalistic model of healthcare to more personalized healthcare in which disease management is conducted by the patient together with their healthcare providers. The increasing utility of mHealth is expected to benefit disease management, promote patient-doctor communication, reduce medical expenses, and optimize medical services.

Preliminary study of the validity and reliability of the Chinese version of the Saint Louis University Mental Status Examination (SLUMS) in detecting cognitive impairment in patients with traumatic brain injury

The Saint Louis University Mental Status Examination (SLUMS) has been shown to be useful in the cognitive assessment in older adults and patients with dementia. The aim of this study was to preliminarily explore the effectiveness of the Chinese version of the SLUMS in the detection of cognitive impairment in patients with traumatic brain injury (TBI) and to provide an objective basis for its clinical application in China. In this cross-sectional study, 42 patients with TBI and 30 matched normal controls were administered. Participants were assessed by the Chinese version of the Mini-Mental State Assessment scale (MMSE), Montreal Cognitive Assessment scale (MoCA) and SLUMS. Results showed that the Chinese version of the SLUMS had satisfactory internal consistency (Cronbach's α coefficient: 0.723), excellent interrater reliability (ICC: 0.990–0.998) and intrarater reliability (ICC: 0.968), as well as good validity. In the TBI group, the total SLUMS score was moderately positively correlated with the MMSE score (r = 0.702, p = .000) and highly positively correlated with the MoCA score (r = 0.831, p = .000). Receiver Operating Characteristic (ROC) curve analyses showed that the area under the curve (AUC) of the SLUMS, MMSE and MoCA were 0.872, 0.756 and 0.916, respectively. The optimal cutoff score of 22.5 or fewer points are suggested for the SLUMS to discriminate cognitive impairment, with a sensitivity of 0.844 and a specificity of 0.825. The Chinese version of the SLUMS has excellent reliability and validity, and can be used as a screening tool for cognitive impairment of patients with TBI in China.

Extraction, Characterization, Antitumor and Immunological Activities of Hemicellulose Polysaccharide from Astragalus radix Herb Residue.

Astragalus radix (radix) have been frequently used for clinical application in China, and the herb residues of radix turn out to be a waste of resources. To escape from this, the medicine value of radix herb residues is mined in this article. We isolated hemicellulose polysaccharide AX-I-3b from radix herb residues by fractional extraction. Monosaccharide-composition analysis revealed that AX-I-3b consisted of arabinose, xylose, and glucose with a molar ratio of 10.4:79.3:1.1. Methylation, NMR and FT-IR analyses showed that AX-I-3b monosaccharide residue was linked as follows: →2,3,4)-β-d-Xylp-(1→, →4)-β-d-Arap-(1→, →4)-β-d-Glcp-(1→. Then, we found that AX-I-3b exhibited antitumor activity against lung cancer in vitro and vivo through MTT assay and xenograft tumor model. Mechanistically, AX-I-3b induced apoptosis in lung cancer cells and xenograft tumors, which is evidenced by the up-regulation of p53, Bax and cleaved caspase-3, and the down-regulation of Bcl-2. Moreover, AX-I-3b synergistically improved the therapeutic ability of cisplatin in xenograft tumors model. Furthermore, AX-I-3b treatment effectively improved the immune organ index, the percentage of spleen lymphocyte subsets and serum cytokine levels in lung cancer mice, supporting that AX-I-3b showed immunomodulatory activity. In conclusion, our results identified AX-I-3b as an antitumor and immunomodulatory agent, providing a new insight into the reutilization of radix herb residue.

Implementation of water safety plans in China: 2004-2018.

The application of Water Safety Plans (WSPs) in China varies throughout the country. Although pilot WSP projects in China were initiated shortly after WSP was introduced by the World Health Organization (WHO) in 2004, they have yet to be used for water supply facilities at a large scale. To better understand the evolution of WSP application in China, a systematic review was conducted to identify all published WSP related studies in China. Eighteen studies, which included 311 water systems, were included in the final analysis. Risk matrix, water supply risk factors, and other data were extracted and analyzed. Text mining methods were also used to better understand risks that can be addressed by WSPs (both potential and actual risks). This study revealed a number of noteworthy differences between and among urban and rural water systems in China. The primary risks associated with most urban water supply systems tended to be related to mechanical failure/s in the water treatment process. Rural water supply systems appear to suffer from similar problems, but insufficient overall management capacity was more prevalent in rural systems. Overall, the evidence suggests that, to date, the use of WSPs in China has been primarily limited to pilot studies, and full implementation of WSPs in China appears to still be in the early stages. The paper closes with a summary of the key obstacles identified as well as a discussion of policies and technical options which could increase the use of WSPs in both urban and rural China. Among other recommendations, the data indicate that there is strong need for the development and implementation of a simplified WSP approach designed specifically for small rural systems in China.

A History Matching Framework to Characterize Fracture Network and Reservoir Properties in Tight Oil

Abstract Accurately characterizing hydraulic fracture network and tight oil reservoir properties can lay the foundation for the production forecast and development design. In this work, we proposed a history matching framework for tight oil. We first use the Hough transform method to characterize complex fracture network from microseismic data. Then, we put the fracture network into an embedded discrete fracture model (EDFM) to build a tight oil reservoir simulation model. After that, we further couple whale optimization algorithm (WOA) and EDFM to match the field production data. In this way, we can accurately estimate reservoir properties, including matrix permeability and porosity, as well as fracture permeability. We apply the framework to two-field applications in China. One is fractured vertical well in the Songliao Basin of Daqing oilfield. The other one is multi-stage fractured horizontal well in the Jimsar Sag of the Xinjiang oilfield. Results show that if we do not consider tight oil characteristics, the estimated fracture permeability, matrix permeability, and matrix porosity will underestimate 73%, 20%, and 47%, respectively. Because we apply WOA to history matching for the first time, we compare the performance of WOA with ensemble–smoother with multiple data–assimilation (ES-MDA). When we fit six parameters, ES-MDA performs better than WOA. However, when we fit three parameters, WOA performs better than ES-MDA. In addition, for engineering problem, WOA performs well on both convergence speed and stability. Therefore, WOA is recommended in the future application of history matching.

User continuance of a green behavior mobile application in China: An empirical study of Ant Forest

Abstract In China, a new green behavior mobile application named Ant Forest was lunched, in which users can plant trees to protect the environment. Ant Forest offers an information technology based way that enables people to engage in green behavior. The application has attracted a large number of users, and millions of trees have been planted. However, the users' participation in this new kind of green behavior has been rarely studied in current literature. To fill this gap, we built a research model to study antecedents of user's continue intention to use Ant Forest. Survey data were collected from Ant Forest users and 278 valid questionnaires were received. Partial least squares path modeling method was used to analyze the data. Results show that satisfaction influence users' intention to continue using Ant Forest. Environmental concern, perceived enjoyment, and game interaction have positive influence on satisfaction, while perceived cost has negative influence on satisfaction. This paper contributes to researchers' understanding of green and low-carbon behaviors. In addition, suggestions on promoting new forms of green and low-carbon behavior were proposed for policy makers, and management suggestions on how to promote Ant Forest were also proposed which may benefit Ant Forest managers.

Foreign Direct Investment Dynamic Performance with Low-Carbon Influence: A Provincial Comparative Application in China

Cross-border capital flows have been a major force driving economic globalization. Foreign direct investment (FDI) plays a decisive role in seeking out market technology brands and enhancing the global competitiveness among international inflows. With the requirement of economic development, this paper focused on a performance evaluation of FDI in China. However, because of the planned transformation to a market economy in China, FDI has been promoted with a regional cascade structure. Similar to the development track of the Chinese economy, it is necessary to evaluate FDI quality more than purely quantity from a provincial point of view. Therefore, this paper evaluated the Chinese provincial FDI total factor productivity using the dynamic Malmquist model. In contrast to traditional evaluations, this paper focused on inter-temporal influence in FDI performance evaluation. To understand the inter-temporal effects, physical capital stock was defined as a dynamic variable in FDI sustainability performance. Additionally, with the pressure to reduce emissions, energy consumption was also considered during the evaluation. The empirical results revealed that the dynamic variable is the bottleneck in FDI performance for most Chinese provinces. It is only efficient in a few municipalities and provinces, such as Shanghai and Guangdong. Additionally, energy conservation was more efficient in the performance evaluation of eastern regions in China.

Input of Cd from agriculture phosphate fertilizer application in China during 2006–2016

Phosphate fertilizer applications are an important source of soil Cd in China. However, the input of Cd from phosphate fertilizer has always been neglected in China because of its low content. In this paper, we calculated the Cd input from phosphate fertilizer in China during 2006–2016. According to the data, the total phosphate fertilizer consumption and agriculture application rate tended to decrease after 2014. In 2016, the phosphate fertilizer application rate ranged from 12.14 to 99.38 kg/ha with a mean value of 42.70 kg/ha, and excessive fertilizer application occurred in Xinjiang, Henan, and Hubei Provinces. The Cd content in phosphate fertilizer was 0.75 mg/kg based on 1222 samples. The national Cd input from phosphate fertilizer was estimated to be 10.52 tons in 2016, with DAP/MAP being the largest contributor, accounting for 83.31% of the total input. These findings demonstrate the necessity of performing assessments to regulate the utilization of phosphate fertilizer in China, especially in Henan and Xinjiang Provinces.

Mapping the distribution of foreign applications for patents in China, 1987–2017

Despite the growing number of foreign applications for patents in China, the spatial distribution of countries that have applied for patents in China, as well as its evolution, has yet to be investigated. By using cartograms, this paper aims to show the evolving distribution of countries that have applied for patents in China from 1987 to 2017. First, we find that the number of patents applied for in China has been far from evenly distributed across countries. Rather, it has been mainly concentrated in several countries such as Japan, the USA, and Germany. Second, the distribution pattern changed a lot during the first decade of the study period and has remained relatively stable over the last two decades. Third, recent years have also seen an increasing number of patent applications in China by some offshore financial markets like the Cayman Islands, where many high-tech companies are registered.

Smart City: A Shareable Framework and Its Applications in China

Smart City is a new concept that uses information and communication technology (ICT) to promote the smartification of urban construction, planning and services. Currently, a number of cities have conducted studies on smart cities, but they have mostly focused on analyzing the conceptual connotations or applications in specific domains and lack a shareable and integrated framework, which has led to significant barriers for individual smart projects. By analyzing the framework and applications of Smart City, this paper proposes a common, shareable and integrated conceptual framework. Then, based on this framework, it further proposes a unified portal platform that can balance multiple stakeholders, including the government, citizens and businesses, as well as for common, custom and other application modes. Finally, the implementation of Smart Weifang based on this platform is discussed. The applications indicate that this shareable platform can effectively eliminate the data and technological barriers between different smart city systems while also avoiding redundant financial investments. The investigation of this proposed framework and platform is highly significant for the unified construction of smart cities and the intensification of the hardware environment, thus representing a true achievement in the transition from ‘information islands’ to ‘information sharing and interconnection’ for urban informatization.
