Consumer switching behaviors are influenced by the word-of-mouth (WOM) phenomenon, yet our knowledge on the relationship between WOM and mobile payment application switching behaviors is rather limited. This paper examines how the valence and targets of WOM influence mobile payment application switching behaviors. Drawing on social influence theory and gender-related works, we examined whether the strength of the paths between WOM and switching behaviors differs across genders. The model was tested using a large-scale survey of 3,785 valid responses. The empirical results suggest that perceived alternative attractiveness and trust bridge the relationship between WOM and switching behaviors. Further, the effects of positive and negative WOM on perceived alternative attractiveness appear greater for females than for males. [ABSTRACT FROM AUTHOR]

An efficient adsorption material--thiourea modified bagasse biochar (TBC) was prepared using bagasse. TBC was characterized by scanning electron microscopy coupled to EDS (SEM-EDS), Fourier transform infrared (FTIR), Brunauer-Emmett-Teller (BET) and X-ray diffractometer (XRD). Furthermore, TBC adsorption performance was researched, using norfloxacin (NOR) as target pollutant. In this research, different influencing factors were studied, such as the solution pH, contact time, initial NOR concentration and the adsorbent dosage. In addition, the adsorption isotherms could be described well with Langmuir model, with the maximum NOR adsorption capacity of 193.19 mg-L_1. The kinetics data revealed that the adsorption of NOR on TBC conformed to the pseudo-second-order. Based on the results, the adsorption process was monomolecular chemical adsorption.

An easily recyclable composite NGO-Fe3O4 was synthesized, characterized, and evaluated as a heterogeneous catalyst for activation of peroxydisulfate (PDS). In this study, a novel UV-enhanced heterogeneous NGO-Fe3O4/peroxydisulfate (UV/NGO-Fe3OVPDS) system was developed and investigated for the degradation of an antibiotic sulfadiazine (SDZ). 99.1% SDZ could be removed within 30 min in UV/NGO-Fe3O4/PDS, while for UV/NGO-Fe3O4, NGO-Fe3OVPDS and UV/PDS system it was 57.7%, 43.2% and 49.1%, respectively. Better synergetic effect between UV irradiation and NGO-Fe3O4/PDS system was observed. The SDZ degradation in the UV/NGO-Fe3O4/PDS system could be applied by the first-order kinetic with a /c,i,s(SDZ) value of 0.148 min-1. Affecting factors such as initial pH, dosage ratio of [NGO-Fe3O4]:[PDS] and initial concentration of SDZ were further studied. Scavenging tests by tert-butyl alcohol and methanol confirmed that both hydroxyl radicals ('OH) and sulfate radicals (SO4-') are responsible for the degradation of SDZ, with the latter playing a more significant role. Finally, Five possible degradation pathways of SDZ by UV/NGO-FOVPDS were proposed based on theoretical reactive sites attacked by radicals and intermediate products. [ABSTRACT FROM AUTHOR]

The method of DNS data collection is one of the most important parts of DNS simulation. DNS data contains a lot of information. When it comes to analyzing the DNS security issues by simulation on the cyber range with customized features, we only need some of them, such as IP address, domain name information, etc. Therefore, the data we need are supposed to be light-weighted and easy to manipulate. Many researchers have designed different schemes to obtain their datasets, such as LDplayer and Thales system. However, existing solutions consume excessive computational resources, which are not necessary for DNS security simulation. In this paper, we propose a light-weighted active data collection method to prepare the datasets for DNS simulation on cyber range. We evaluate the performance of the method and prove that it can collect DNS data in a short time and store the collected data at a lower storage cost. In addition, we give two examples to illustrate how our method can be used in a variety of applications. [ABSTRACT FROM AUTHOR]

There are extensive empirical studies on online health communities (OHCs)--important platforms that help users manage their health conditions. However, little research has concentrated on the role of social support networks and user engagement. This paper aims to investigate the influence of social support networks on users' health conditions via user engagement in health tasks, alongside the moderating effects of gender differences. We established a twoequation model using the data of 1,129 users in an OHC. The empirical results of our research model reveal that the size of a social support network, as well as individual activities and group member activities within the network, are positively associated with levels of user engagement in online health tasks. This paper also finds that the interactive relationship between three factors--(1) the association of social support network size and (2) individual user activities with (3) levels of user engagement--is complementary; further, it finds that the relationship between (1) social support network size, (2) group member activities, and (3) levels of user engagement is substitutable. Moreover, we observe that levels of user engagement in health tasks are positively related to users' health conditions. In addition, our results show the moderating effects of gender differences on the relationship between social support, levels of user engagement in health tasks and user health conditions. The findings of this paper add value to the literature on OHCs and provide some insights into the management of OHCs for practitioners. [ABSTRACT FROM AUTHOR]

As an excellent catalyst toward hydrogen peroxide reduction, Fe-based nanomaterial like Fe-N-C configuration is promising candidate to be used for H2O2 sensing. In this work, a novel N-doped mesoporous carbon by atomically dispersed Fe-N dopant composite modified electrode (Fe/NOMC) was prepared by hard template approach and then fabricated non-enzymatic sensor was used for H2O2 determination. The morphology and property of Fe/NOMC composite were characterized by transmission electron microscopy (TEM), energy-dispersive X-ray spectroscopy (EDX), small angle X-ray diffraction (XRD) spectrum and nitrogensorption measurement, respectively. The electrochemical sensing performance of the Fe/NOMC composite modified glassy carbon electrode (GCE) was studied by cyclic voltammetry and chronoamperometry methods. An excellent performance toward hydrogen peroxide reduction was achieved in a wide range of 8-23000 μM, with limitation of detection (LOD) about 5 μM and a correlation coefficient of 0.998, as well as a short response time (2 s) and good selectivity.

To better regulate the airport cargo transportation, we presented the design of an airport logistics monitoring system based on WSN and RFID. The monitoring system is mainly composed of four modules: RFID system, wireless sensor monitoring network, communication network and remote monitoring terminal. Wireless sensors mainly include temperature sensors, humidity sensors and smoke sensors. The sensors can collect the environment data such as goods temperature, humidity and smoke and so on. The node sensor module is implemented in such a way that the sensor is connected to the node in a plugin manner, that is, the sensors are integrated on a sensor panel and the sensor data is transferred through the standard I / O interface between the sensor panel and the node. The system can realize real-time tracking and positioning of airport cargo, collecting cargo information. [ABSTRACT FROM AUTHOR]

Background and objective Lung cancer is the most common malignancy and screening can decrease the mortality. High quality screening guideline is necessary and important for effective work. Our study is to review and evaluate the basic characteristics and methodology quality of the current global lung cancer screening guidelines so as to provide useful information for domestic study in the future. Methods Electronic searches were done in English and Chinese databases including PubMed, the Cochrane Library, Web of Science, Embase, CNKI, CBM, Wanfang, and some cancer ofcial websites. Articles were screened according to the predefned inclusion and exclusion criteria by two researchers. The quality of guidelines was assessed by AGREE II. Results At last, a total of 11 guidelines with methodology were included. The guidelines were issued mainly by USA (81%). Canada and China developed one, respectively. As for quality, the average score in the "Scale and objective" of all guidelines was 80, the average score in the "Participants" was 52, the average score in the "rigorism" was 50, the average score in the "clarity" was 76, the average score in the "application" was 43 and the average score in the "independence" was 59.
