Empirical Study on the Impact of Domestic Economic Cycle on Sichuan’s Tourism  [PDF]
Junrong Liu, Qin Yan
Journal of Service Science and Management (JSSM) , 2012, DOI: 10.4236/jssm.2012.53034
Abstract: This article empirically enquires, from the perspective of demand, the impact of economic cyclical fluctuation on Sichuan tourism. The findings show that Sichuan tourism demand proves elastic to CPI, Sichuan’s GNI capita and interest rate, and that CPI and interest rate fluctuations are negatively correlated with Sichuan domestic tourism demand, while, with which Sichuan’s GNI capita is positively associated. The study also finds that per capita national income and the local consumer price index enjoy strong predictive power for Sichuan tourism.

Are Religious Affections Positive or Negative?—The Role of Religious Affections on Executive Control  [PDF]
Hailan Liu, Qin Zhang
Psychology (PSYCH) , 2013, DOI: 10.4236/psych.2013.412140

The present study investigated the influence of religious affections on executive control compared with positive and negative emotions using emotional priming paradigm and the letter flanker task. 58 participants (Tibetan Buddhists, 28 males and 30 females) were required to identify the central target letter after primed by religious, positive, or negative pictures. There was a space (loose) or no space (close) between neighboring letters. The results revealed that in close condition both religious affections-prime and negative emotional-prime reduced the flanker effect in response accuracy (ACC) compared to positive emotional-prime for female participants. It means that religious affections do not function as positive emotions on executive control. Moreover, for females, when primed by religious pictures, the ACC flanker effect was negatively related to the arousal of religious pictures, but when primed by negative pictures, the flanker effect in response time was positively related to the valence of negative pictures. The correlation analysis indicates that religious affections and negative emotions may influence executive control in different ways. These findings suggest that religious affections exert their special influence on executive control, not simply positive or negative.

The Empirical Research of the Influence of Leadership Positive Emotion on Counterproductive Work Behavior  [PDF]
Peng Qin, Yaozhong Liu
Psychology (PSYCH) , 2019, DOI: 10.4236/psych.2019.106057
Abstract: Leader’s emotion is one of the most influential factors of employee behavior in the workplace. The expression or of a leader’s positive emotion can directly or indirectly affect the employee’s work performance, especially the employee’s Counterproductive Work Behavior (CWB). This paper systematically explains the internal mechanism how the leader’s positive emotion affects employees’ CWB through experimental methods, and uses the Emotions As Social Information Modle (EASI) to analyze and explain the research results. Finally, this study exposes the inner psychological process of Leader’s positive emotion affecting employees’ CWB through their own positive emotions, proving the moderating effect of leadership justice in this process, and this study enriches the results of the research field of CWB.
Stationary phase approach to the quasiparticle interference on the surface of three dimensional strong topological insulators
Qin Liu
Physics , 2011,
Abstract: Constant energy contour (CEC) of the surface bands in topological insulators varies not only with materials but also at different energies. The quasiparticle interference caused by scattering-off from defects on the surface of topological insulators is an effective way to reveal the topologies of the CEC and can be probed by scanning tunneling microscopy (STM). Using stationary phase approach, a general analytic formulation of the local density of states as well as the power laws of the Friedel oscillation are present, based only on the time-reversal symmetry and the local geometry around the scattering end points on the CEC. Distinct response of surface states to magnetic impurities from that of nonmagnetic impurities is predicted in particular, which is proposed to be measured in a closed "magnetic wall" setup on the surface of topological insulators.
The Correlation between Social Anxiety and Loneliness of Left-Behind Children in Rural China: Effect of Coping Style  [PDF]
Chuanjing Liao, Qin Liu, Jinfu Zhang
Health (Health) , 2014, DOI: 10.4236/health.2014.614204
Abstract: In this study, the relationship between social anxiety, coping style and loneliness amongst left-behind children was investigated. The participants were 773 left-behind children recruited from 8 junior middle schools in rural areas of Zhejiang Province in China who completed the Social Anxiety Scale for Children, Simplified Coping Style Questionnaire and Children’s Loneliness Scale. Results show that there was a moderate correlation between social anxiety and loneliness, and these variables had a significant negative relationship with positive coping style and a significant positive relationship with negative coping style. Furthermore, the left-behind children’s social anxiety, coping style and loneliness were different within specific demographic groups, such as gender, only child status and different type of parental work. Also negative coping style moderated the association between loneliness and social anxiety, so that children who were more likely to use negative coping strategies showed a stronger relationship between social anxiety and loneliness. Finally, the left-behind children’s social anxiety not only directly predicted their loneliness, but also had an indirect effect mediated by their copying style.
Rate Adaptation for Decoding-and-Forward Relay Channel by Random Projections Codes  [PDF]
Min Wang, Qin Zou, Caihui Liu
Journal of Computer and Communications (JCC) , 2016, DOI: 10.4236/jcc.2016.44015
Abstract: This paper investigates rate adaptation schemes for decoding-and-forward (DF) relay system based on random projections codes (RPC). We consider a classic three node relay system model, where relay node performs on half-duplex mode. Then, we give out receiving diversity relay scheme and coding diversity relay scheme, and present their jointly decoding methods. Furthermore, we discuss the performance of the two schemes with different power allocation coefficients. Simulations show that our relay schemes can achieve different gain with the help of relay node. And, we should allocate power to source node to just guarantee relay node can decode successfully, and allocate remain power to relay node as far as possible. In this way, this DF relay system not only achieves diversity gain, but also achieves higher and smooth spectrum efficiency.
Characterizing Subzero-Temperature Thermal Properties of Seasonally Frozen Soil in Alpine Forest in the Western Sichuan Province, China  [PDF]
Hui Sun, Shuai Liu, Jihong Qin
Journal of Water Resource and Protection (JWARP) , 2016, DOI: 10.4236/jwarp.2016.85048
Abstract: Seasonally frozen soil in alpine and subalpine zones in the mountains of Qinghai-Tibetan Plateau is particularly sensitive to global climate change. Therefore, a better understanding of the thermal properties of frozen soil is crucial for predicting the responses of frozen soils to soil warming. In this study, thermal properties of frozen soil with different moisture contents under subzero temperature (0°C - 20°C) in an alpine forest in western Sichuan were analyzed by KD2 Pro in its cooling and heating processes, respectively. Our results reveal that the soil apparent volumetric specific heat capacity (Cv) and apparent thermal conductivity (K) under the same water content show similar response patterns to changing temperature lower than -2°C in both heating and cooling processes. Moreover, ice content of frozen soils can be well predicted by Logistic model in cooling and heating processes. The Cv and K tend to increase along with increasing soil moisture contents. Remarkably, asymptotic characters of the value of Cv and K are at the vicinity of the initial temperature of phase transitions, indicating that both Cv and K are particularly sensitive to changing soil temperature at the range of -2

Wenyu Qin, Xiang Liu, Zhibin Kong
Open Journal of Social Sciences (JSS) , 2018, DOI: 10.4236/jss.2018.66009
Abstract: Objectives: To explore the characteristics of road traffic accident casualties and time distribution characteristics of road traffic crashes in Guilin. Methods: We analyzed the data of road traffic crashes in 2007-2014 of Guilin to explore the casualty’s features of road traffic injuries and time distribution characteristics of road traffic crashes. Results: A total of 3162 road traffic accident casualties were studied. The majority of the study subjects were males (63.23%) who suffered almost twice as females. The casualties’ ages ranged from 5 to 78 years with the mean age 33.65 ± 16.76 years. The mortality rate of RTCs was significantly higher in males than in females (61.39 versus 38.61, P < 0.05). RTIs disproportionately affected adult people, with the majority of those fatalities occurred among people aged 15 - 59 years. The mortality rates of RTCs varied greatly by educational status, more than one-third occurred in people of secondary school. Approximately 40.25% of fatalities of road traffic crashes occurred in daily laborer showed that mortality rate was significantly higher than other occupations (P < 0.05). The distribution of season from road traffic deaths involved Spring (24.72%), Summer (15.56%), Autumn (30.56%), and Winter (29.17%). The proportion of road traffic deaths varied from the lowest 6.02% in 9:00 - 12:00 to the highest 16.78% in 0:00 - 3:0; midnight (0:00 - 3:00) shows a significantly higher proportion of reported road traffic deaths (P < 0.05). The upper limbs and lower limbs were the most common body region injured accounting for 16.57% and 17.84% of cases respectively; the highest fatality rate of head was 20.77% and followed by abdomen of 15.75%. Conclusions: This study showed diverse morbidity and mortality characteristics among the casualties and varied the road traffic accident rate and fatality rate from season and time. Corresponding measures to reduce the occurrence of traffic injuries should be formulated according to different population and time.
Effect of Ice-Temperature and Spermidine on Chilling Sensitivity of Pepper  [PDF]
Dongjie Liu, Guoliang Sui, Yongzhou He, Wen Qin, Ji Liu
Food and Nutrition Sciences (FNS) , 2013, DOI: 10.4236/fns.2013.42022

The peppers which were treated at ice-temperature for 6 hours and 1 mmol/L spermidine for 10 min, followed by cold storage (4 ± 1) respectively were investigated. The results indicated that the chilling injury was delayed and reduced by ice-temperature and spermidine treatments. Comparing with control group, ice-temperature and spermidine exerted significant effects on reduction of ascorbic acid (Vc) and chlororphyll contents, relatively high activity of superoxide dismutase (SOD), accumulation of malondialdehyde (MDA) as well as the increase of cell membrane penetrability. The results indicated that the spermidine and ice-temperature induced the activity of antioxidant enzyme SOD and maintained higher defence-related compound Vc as well as lower levels of membrane lipid peroxidation, which may be associated with chilling injury alleviation. There was a difference between ice-temperature treatment and spermidine treatment after 30 days. The results suggested that spermidine was more effective in reducing chilling sensitivity and prolonging storage of peppers.
