摘要：
The multi-functionality of paddy farming has become a hot issue recently. Paddy farming provides numerous ecosystem services that are crucial to human well-being. However, evaluation of the contribution of paddy farming to human well-being usually focus on its economic value, while its non-market services are usually ignored. Only evaluating the market profits or market relative benefits cannot reflect comprehensively the contribution of paddy farming to people's well-being. This will affect people's choices for or against paddy farming activities and people's opt for invest or not invest in it. A comprehensive evaluation of paddy farming can provide an important reference for the government and society to conserve the multi-functionality of paddy farming and achieve sustainable development. To this end, this paper reports a case evaluation of paddy farming in Hunan, the largest rice producing as well as rice yield province in China, and uses emergy theory to make a comprehensive evaluation for paddy farming. The emergy evaluation results of the paddy ecosystem in Hunan are as follows: in 2010, the input emergy of the paddy ecosystem in Hunan is 2.51E+22 sej and the output emergy is 6.31E+22 sej. For the input emergy, the part from natural resources is 1.96E+21 sej and the part from human society is 2.32E+22 sej; for the output emergy, the part from products is 2.22E+22 sej, the part from impositive externality is 4.16E+22 sej and the part from negative externality is –7.41E+20 sej. Taking the non-market outputs into consideration, the gains from the human economic society's 1 $ input in paddy farming, emergy sustainability index(ESI)and emergy profit rate are respectively 2.73 $, 3.53 and 151.31%. If the evaluation leave out the non-market output, the three indexes are only 0.96 $, 1.24 and 30.67%. The research results show that non-market services of paddy farming contribute significantly to human well-being. Therefore, in order to protect the multi-functionality of paddy farming and achieve the sustainable management, the government should take reasonable measures and make incentive plans.

摘要：
In order to detect and quantify asymmetry of two time series, a novel cross-correlation coefficient is proposed based on recent asymmetric detrended cross-correlation analysis (A-DXA), which we called A-DXA coefficient. The A-DXA coefficient, as an important extension of DXA coefficient rho(DXA), contains two directional asymmetric cross-correlated indexes, describing upwards and downwards asymmetric cross-correlations, respectively. By using the information of directional covariance function of two time series and directional variance function of each series itself instead of power-law between the covariance function and time scale, the proposed A-DXA coefficient can well detect asymmetry between the two series no matter whether the cross-correlation is significant or not. By means of the proposed A-DXA coefficient conducted over the asymmetry for California electricity market, we found that the asymmetry between the prices and loads is not significant for daily average data in 1999 yr market (before electricity crisis) but extremely significant for those in 2000 yr market (during the crisis). To further uncover the difference of asymmetry between the years 1999 and 2000, a modified H statistic (MH) and DMH statistic are proposed. One of the present contributions is that the high MH values calculated for hourly data exist in majority months in 2000 market. Another important conclusion is that the cross-correlation with downwards dominates over the whole 1999 yr in contrast to the cross-correlation with upwards dominates over the 2000 yr.

摘要：
This study examined core self-evaluations (CSEs) and coping styles as mediators of the relationship between social support and well-being. Participants included 722 Chinese university students who completed the Multidimensional Scale of Perceived Social Support, the Core Self-Evaluations Scale, the Simplified Coping Style Questionnaire, the Positive and Negative Affect Schedule, and the Satisfaction with Life Scale. Social support, CSEs, and positive coping were positively correlated with life satisfaction and positive affect and negatively correlated with negative affect. Negative coping was positively correlated with negative affect and negatively correlated with family support. CSEs and coping styles partially mediated the effects of social support on life satisfaction and positive affect. Furthermore, CSEs completely mediated the link between negative affect and social support. High social support improved self-evaluations; this, in turn, contributed to higher levels of wellbeing. Social support also decreased the negative effects of coping on life satisfaction and positive affect Specifically, individuals with high social support were more likely to develop more positive and less negative coping; this resulted in higher levels of life satisfaction. These findings contribute to a better understanding of the relations between these factors. Future studies should examine the mediational model using multiple methods. (C) 2015 Elsevier Ltd.

Hope;Latent class analysis;Chinese adolescents
摘要：
Using latent class analysis, we explored the within-person configurations of hope in a sample of Chinese adolescents. A total of 1688 adolescents (801 boys and 887 girls) from Mainland China completed measures of hope, life satisfaction, self-esteem, and depression. Obvious grouping features appeared, and a model of the three latent classes was supported. The three classes of ‘high hope’, ‘average hope’, and ‘low hope’ accounted for 32%, 47.5%, and 20.5% of the variance respectively. Compared to the average- and low-hope classes, the high-hope class reported significantly higher levels of life satisfaction, self-esteem and optimism and lower levels of depression, suggesting that higher levels of hope are adaptive in non-Western cultures as well as Western ones.

摘要：
Biomass is one of the renewable energy sources on which policy makers are greatly dependent on since it is a flexible feedstock capable of conversion into electricity, transport liquid fuels and heat by chemical and biological processes on demand. Though numerous publications have examined the relationship of economic growth with renewable energy and other parameters, biomass energy has never been included in these studies. Then, this study examines the causal relationship within a multivariate panel cointegration/error correction framework which combines the cross-section and time series data while allowing for heterogeneity across different provinces. After employing panel data regression model ranging from 2003 through 2012 to examine the relationships of biofuels production with sustainable development in China, the paper concludes that the development of biofuel energy production integrated with the consideration of the improvement of income per capita, and the attraction of more capital investment, does make a significant contribution to economic growth. However, some negative side effects including the increase of greenhouse emissions and the decrease of marginal land still coexist with the economic development. Of course, the importance of these findings lies on their implications and their adoption on strategic policies.
摘要：
The Brown Assessment of Beliefs Scale (BABS) is a semi-structured, clinical interview scale measuring insight/delusionality in problems such as obsessive-compulsive disorder (OCD). The BABS is widely used, but few studies have examined its psychometric properties in OCD patients; and existing studies have small sample sizes. The present study aimed to establish a Chinese version of the BASS and assess its psychometric properties in a relatively large sample of 171 outpatients with OCD. Results showed that the internal consistency as well as the convergent and divergent validity of the Chinese version of the BABS was acceptable. The ICCs demonstrated good interrater reliability and test-retest reliability and a confirmatory factor analysis supported the original one-factor structure. Moreover, the results provided further evidence that OCD patients' insight varies widely, and that the Chinese version of the BABS could be used to assess insight/delusionality in OCD.

摘要：
This study applies two variables in the measurement of company patent deployment strategies: patent family depth and earn plan ratio. Patent family depth represents the degree to which certain fields and markets are valued by the patent owner. Earn plan ratio defined as the ratio of the number of patent forward citations to patent family size. Earn plan ratio indicates the degree to which a patent family could be cited by later innovators and competitors. This study applies a logistic regression model in the analysis LED industry data. The results demonstrate that patent value has a positive relationship with the patent family depth, and earn plan ratio.

摘要：
We investigated the origins of individual differences in hope in adolescents based on a social-cognitive model. Specifically, we examined a mediating role for self-esteem and optimism in the relation between social support and hope. One thousand six hundred fifty four adolescents (781 boys and 873 girls) from Mainland China completed the Multidimensional Scale of Perceived Social Support (MSPSS), the Rosenberg Self-Esteem Scale (RSES), the revised Life Orientation Test (LOT-R) and the Children's Hope Scale (CHS). Social support was associated positively with self-esteem, optimism and hope, and hope was associated positively with self-esteem and optimism. Structural equation modeling analyses revealed that self-esteem and optimism partially mediated the relation between social support and hope, accounting for 62.7% of the effect of social support on hope. The significance and limitations of the results are discussed. (C) 2015 Elsevier Ltd. All rights reserved.

摘要：
Anhedonia is one of the core negative symptoms of schizophrenia that affect the ultimate outcome of this disorder. It is unclear whether the motivational or the hedonic component of anhedonia is impaired in patients with schizophrenia. This study examined the deficits in motivation and hedonic capacity in patients with schizophrenia using an Effort-based pleasure experience task (E-pet). Twenty-two schizophrenia patients with prominent negative symptoms, 18 schizophrenia patients without prominent negative symptoms and 29 healthy controls participated in the present study. All of them were administered the E-pet task, which required the participants to make decisions on whether to choose a hard or easy task based on probability and reward magnitude. When making the grip effort allocation decision, schizophrenia patients with prominent negative symptoms were significantly less likely to choose a hard task than healthy controls. As the reward magnitude and the estimated reward value increased, unlike healthy controls, schizophrenia patients with prominent negative symptoms did not increase their hard task choices. They were also significantly less likely to choose a hard task than healthy controls in medium and high probability conditions. When anticipating potential rewards, these patients reported significantly less anticipatory pleasure than healthy controls, even when reward probability and magnitude increased. The pleasure experience rating after obtaining the actual reward was positively correlated with two pleasure experience scales in schizophrenia patients. In conclusion, patients with schizophrenia, especially those with prominent negative symptoms, showed deficits in both reward motivation and anticipatory pleasure experience. (C) 2015 Elsevier B.V.

摘要：
This study employs a panel threshold regression model to test whether the patent h–index has a threshold effect on the relationship between patent citations and market value in the pharmaceutical industry. It aims to bridge the gap in extant research on this topic. This study demonstrates that the patent h–index has a triple threshold effect on the relationship between patent citations and market value. When the patent h–index is less than or equal to the lowest threshold, 4, there is a positive relationship between patent citations and market value. This study indicates that the first regime (where the patent h–index is less than or equal to 4) is optimal, because this is where the extent of the positive relationship between patent citations and market value is the greatest.
摘要：
Anhedonia is a hallmark symptom of major depressive disorder (MDD). Preliminary findings suggest that anhedonia is characterized by reduced reward anticipation and motivation of obtaining reward. However, relatively little is known about reward-based decision-making in depression. We tested the hypothesis that anhedonia in MDD may reflect specific impairments in motivation on reward-based decision-making and the deficits might be associated with depressive symptoms severity. In study 1, individuals with and without depressive symptoms performed the modified version of the Effort Expenditure for Rewards Task (EEfRT), a behavioral measure of cost/benefit decision-making. In study 2, MDD patients, remitted MDD patients and healthy controls were recruited for the same procedures. We found evidence for decreased willingness to make effort for rewards among individuals with subsyndromal depression; the effect was amplified in MDD patients, but dissipated in patients with remitted depression. We also found that reduced anticipatory and consummatory pleasure predicted decreased willingness to expend efforts to obtain rewards in MDD patients. For individuals with subsyndromal depression, the impairments were correlated with anticipatory anhedonia but not consummatory anhedonia. These data offer novel evidence that motivational deficits in MDD are correlated with depression severity and predicted by self-reported anhedonia. (C) 2014 Elsevier Ireland Ltd. All rights reserved.

Subjective well-being;Stability;Variation;Latent state-trait model
摘要：
In order to explore the stability and variation of the indicators of subjective well-being (SWB), the classic Latent State-Trait (LST), Trait-State-Occasion (TSO), and Indicator-Specific Trait (IT) models were employed to evaluate the stability and variability of life satisfaction, positive emotions, and negative emotions. The study was conducted based on a 1-year and three-wave longitudinal study with a sample of 360 college students. The results show the suitability of the IT model. The consistency coefficients (CO) of all variables are significantly higher than occasion-specificity coefficients (OSpe) in this model, indicating that stability is a remarkable feature of SWB. Moreover, the consistency coefficients of positive affection and negative affection are much higher than that of life satisfaction, suggesting that the positive and negative emotions of individuals are more stable than life satisfaction.
