摘要：
With the rapid development of China's economy, the agricultural industry chain has a new mode of operation. The rise of big data technology can collect the relevant information of the agricultural industry chain in all aspects more rapidly, accurately and comprehensively, so that the agricultural production, logistics and information flow can be unified, so as to realize the optimization of the resource structure of the industrial chain, and the operation efficiency is higher. In this paper, the analysis method combined with big data was used to construct the industrial chain of ecological agriculture. The ecological agriculture industry in Wuwei was regarded as the specific research object, and a large amount of empirical data was collected by means of consulting literatures and field surveys. The input analysis and output analysis of the agricultural production in Wuwei were carried out and the original industrial chain model was evaluated, and the deficiency of the influence factors was improved. The agricultural industry chain was the developmental situation of a dynamic organization, which had important methodological significances. This paper attempted to put forward some suggestions for the rational development of the agricultural industry chain.

The aim of the current study was to examine the association between age at symptom onset and action cancelation in adults with obsessive-compulsive disorder (OCD). Performance on the stop-signal task was compared among adult patients with early-onset OCD (n = 63, onset age ≤ 19), late-onset OCD (n = 33, onset age ≥ 20), and healthy controls (n = 51). Stop-signal reaction time (SSRT) was significantly longer in both OCD groups compared to the control group. However, no significant differences were found between the two OCD groups. In addition, age at symptom onset was not associated with response inhibition performance in adults with OCD. The study findings support the existence of reduced performance on action cancelation in patients with OCD compared to healthy controls with no difference between early- and late-onset OCD subtypes.

Anhedonia is associated with dysfunction of the neural circuitry of reward in patients with major depressive disorder (MDD). However, its neurobiological basis is not fully understood. The present study examined the association between anhedonia and white matter (WM) characteristics in patients with first-episode MDD. We recruited 30 patients with first-episode drug-naive MDD and 28 healthy controls (HC) to undergo diffusion weighted imaging. We examined specifically the correlation between WM characteristics and anhedonia measured with the Temporal Experience of Pleasure Scale (TEPS) in MDD patients. Using Track-Based Spatial Statistics (TBSS), we found that MDD patients exhibited reduced fractional anisotropy (FA) in the left cingulum and the forceps minor. These patients also exhibited increased radial diffusivity (RD) in several major tracts including the bilateral anterior thalamic radiation, the corticospinal tract, the superior longitudinal fasciculus and the uncinate fasciculus in the left hemisphere. Correlational analysis showed that increased RD was significantly correlated with anticipatory anhedonia in the MDD group, while reduced mean FA was correlated with consummatory anhedonia in HC. These preliminary findings suggest that left-sided WM tracts abnormalities may contribute to the development of anhedonia in MDD patients.

With the continuous development of economy and the integration of the Internet information network, the network language is playing an increasingly important role in people's lives. Since the economists put forward the linguistic economics in 1965, the economic value of language has become the consensus of the people of all countries, and now it is a new and hot topic to study and analyze the English network language. In this paper, a system for evaluating the economic value of English network language was designed. Analytic hierarchy process (AHP) and qualitative methods were used, and the economic value of network language was quantified.

摘要：
Background: Melancholic depression is a relatively homogenous subtype of major depressive disorders (MDD). The condition has several endogenous symptoms and represents strong biological components. However, its specific neurobiological mechanisms remain unknown. Previous neuroimaging findings indicated that default mode network (DMN) is closely related to MDD. The present study examined the network homogeneity (NH) of the DMN in patients with melancholic MDD. Methods: A total of 33 first-episode, treatment-naive melancholic MDD patients and 32 healthy controls underwent a resting-state functional magnetic resonance imaging scan. The data were analyzed using the NH method. Results: Compared with healthy controls, patients with melancholic MDD showed low NH values in the right middle temporal gyrus and temporal pole (MTG/FP). The abnormal NH of this region and clinical characteristics were not correlated. Conclusion: Abnormal NH pattern of DMN exists in patients with melancholic MDD. This feature may be part of the pathophysiological basis of this disorder. (C) 2016 Elsevier B.V. All rights reserved.

摘要：
Impairment in social functioning has been widely described in obsessive-compulsive disorder (OCD). However, several aspects of social cognition, such as theory of mind (ToM), have not been substantially investigated in this context. This study examined cognitive and affective ToM in 40 OCD patients and 38 age-, sex-, and education-matched healthy controls (HCs) with the computerized Yoni task and a battery of neurocognitive tests. OCD symptom severity was assessed with the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS). Depressive and anxiety symptoms were also assessed. Compared to HCs, OCD patients performed worse on second-order affective condition trials, but not cognitive or physical condition trials, of the Yoni task; there were not group differences in any of the first-order condition domains. Second-order ToM performance of OCD patients was associated with estimated intelligence and working memory performance. After controlling for neurocognitive variables, the group difference in second-order affective condition performance remained significant. These findings indicate that the affective component of ToM may be selectively impaired in OCD patients and that the observed deficit is largely independent of other neurocognitive impairments and clinical characteristics.

To facilitate more convenient travel as the economy of Macau expands, the government of Macau has allowed casinos to add free shuttle buses (FSB) and drivers. In this paper, we optimise the operation cost of FSB based on the number of FSB and FSB's driver population in Macau. Firstly, we investigate the operational conditions of the FSB in each depot, including the transit time of FSB and the number of passengers. Then, we propose a series of integer programming models to optimise the population of FSB and FSB drivers. Finally, through a practical demonstration using Excel to solve the linear programming (LP) model, this paper concludes that the numbers of FSB and drivers have a reduction of 43.68% and 33.6%, respectively. It implies that the operation cost of FSB could be reduced by 270,900,000 HKD in purchasing of FSB and 38,678,400 HKD/year in employing drivers of FSB.

摘要：
Using social exchange theory and the social constructivist theory of emotion, I examined the relationship between supervisors' paternalistic leadership and college English teachers' teaching efficacy in China, as well as the roles emotional creativity and professional identity played in this relationship. Participants were 674 teachers of English at 30 colleges in China. Results of factor and correlation analyses, structural equation modeling, and regression analysis revealed that supervisors' paternalistic leadership had significantly positive effects on teachers' teaching efficacy, and that teachers' professional identity had a meditating effect in the relationship between paternalistic leadership and teaching efficacy. In addition, teachers' emotional creativity positively moderated the relationship between supervisors' paternalistic leadership and teachers' teaching efficacy, and emotional creativity acted as a mediated moderator of the link between these two variables. My findings contribute to comprehension of the effect mechanism of supervisors' paternalistic leadership on teachers' teaching efficacy.
摘要：
Obsessive-compulsive disorder (OCD) is characterized by unwanted, intrusive thoughts (obsessions) and/or repetitive, ritualistic behaviors (compulsions). Findings related to the two components of inhibition, namely interference control and behavioral inhibition, among OCD patients have been inconsistent. It might be that this inconsistency is due to the heterogeneity among OCD cases representing multiple subtypes of OCD, such as autogenous obsessions and reactive obsessions types (AOs vs. ROs). AOs and ROs are distinguished by the category of their most disturbing obsessions. The purpose of this study was to systematically examine whether inhibition functions differ between AO and RO patients. We assessed interference control and behavioral inhibition with the emotional Stroop task (EST) and stop-signal task (SST), respectively, in 42 AOs, 55 ROs and 62 healthy controls (HCs) and event-related potentials (ERPs) were recorded in a random subset of these subjects (25 AOs, 25 ROs, and 31HCs). Results showed that in the EST, AOs exhibited longer reaction times (RTs) for color-naming positive-, negative-, and neutral valence word stimulus than both ROs and HCs, and demonstrated larger P2 and less negative N450 amplitudes than HCs and larger P3 amplitudes than ROs and HCs. In the SST, both AOs and ROs showed lengthened stop signal reaction time (SSRT) and reduced Stop-P3 amplitudes in successful inhibition (SI) trials compared to the HC group. These present findings suggest that behavioral inhibition impairment may reflect a common pathology in both the autogenous- and reactive-type OCD patients, whereas interference inhibition impairment appears to be specific to patients with autogenous obsessions. These findings strengthened the insight into the clinical heterogeneity and pathophysiology of OCD. (C) 2016 Elsevier B.V. All rights reserved.
