Abstract: 摘要 从社会距离和空间距离交互形成的心理距离情境视角出发，运用案例研究和定量研究相结合的实证方法，归纳了不同心理距离情境下农户选择农资零售店时的初始信任客体，揭示了心理距离情境和农户初始信任之间的中介机制。研究表明：在社会距离远、空间距离远的心理距离情境1下，农户的初始信任是基于经济理性的产品品牌信任，认知系统信息处理模式在心理距离情境和农户初始产品品牌信任之间发挥中介作用；在社会距离近、空间距离近的心理距离情境3下，农户的初始信任是基于人情的零售商信任，情感系统信息处理模式在心理距离情境和农户初始零售商信任之间发挥中介作用；在社会距离远、空间距离近的心理距离情境4下，农户的初始信任是基于近地理位置属性的零售店信任，直觉系统信息处理模式在心理距离情境和农户初始零售店信任之间发挥中介作用

Abstract: 蔬菜是居民日常生活的重要组成部分，同时也与生产经营者的收入息息相关。蔬菜营销渠道是否畅通直接影响到蔬菜产业的发展和渠道各成员的经济利益。作为蔬菜营销渠道中的重要环节，蔬菜零售商对稳定蔬菜价格、促进蔬菜产业链健康运转发挥着重要作用。本文从经营环境、零售商与批发商、消费者间的博弈关系等几个方面对蔬菜零售商的经营行为的研究进行归纳分析，总结评述国内外学者对影响零售商经营行为的各个因素的相关研究，并针对研究中发现的问题提出相应改进的建议与对策，以期对蔬菜零售商经营行为的进一步研究提供参考。
Vegetables are an important part of the daily life of residents, which are closely linked with the income of production managers. The efficiency of the operations of vegetable marketing channels directly affects the development of vegetable industry and the economic interests of channel members. As an important link in the marketing channel of vegetables, vegetable retailers play an important role in stabilizing prices of vegetables and promoting the healthy operation of vegetable industry chain. This paper summarized and analyzed the researches on the management behavior of vegetable retailers from the perspectives of the operating environment, the game relationship between retailers, wholesalers and consumers. The paper summarized and commented on the domestic and foreign scholars’ studies on the various factors which affect the behaviors of retailers. And some suggestions and countermeasures to improve the issues were put forward in order to provide the reference for further study on vegetable retailers’ operating behaviors.

Modern Marketing (MOM) , 2014, DOI: 10.12677/MOM.2014.44010
Abstract:
评价北京农户的叶类蔬菜渠道绩效时，首先建立相应评价指标体系；其次通过层次分析法建立多阶层次分析模型并计算影响绩效的各因素指标权重，同时基于三角白化权函数的灰色评估方法，评估渠道各层次指标，得到相应渠道绩效的等级和综合评价值。定量评价结论是：“农户 + 企业或合作社”模式的渠道绩效最高，其次是“农户 + 产地集贸市场”和“农户 + 产地收购商”。“农户 + 批发市场”模式的渠道绩效最低，不适于农户进行叶类蔬菜的销售。
Marketing channel efficiency of leafy vegetables was evaluated in this study. The impact factors of leafy vegetable marketing channel efficiency were identified, and then its corresponding evaluation index system was constructed. An evaluation model for multi-hierarchy process based on AHP was established, and the index weights of various factors were calculated. Meanwhile, on the basis of grey evaluation method of triangular whitening weight function, the indexes of various hierarchies in different channels were evaluated and the level and comprehensive evaluation value of performance of marketing channels efficiency were got. The quantitative evaluation results showed that the mode of “Farmers + enterprise (cooperatives)” achieved the highest channel efficiency and the mode of “Farmers + Wholesale” achieved the lowest channel efficiency. The mode of “Farmers + Wholesale” is unsuitable for farmers selling leafy vegetables.
Regional Geochemical Characteristics and Influence Factors of Soil Elements in the Pearl River Delta Economic Zone, China  [PDF]
Lei Dou, Tingting Li
International Journal of Geosciences (IJG) , 2015, DOI: 10.4236/ijg.2015.66046
Abstract: Soil heavy metal pollution is one of the main environmental problems in Pearl River Delta Economic？Zone of China. Based on multi-purpose regional geochemical survey, regional eco-geochemical assessment, local eco-geochemical assessment and comprehensive appraisal, the eco-geochemical survey and assessment in Pearl River Delta Economic Zone of 41,698 km2？were completed. Samples from soils were collected in accordance with the two-layer grid method. Totally 54 elements and indicators for soils were determined. Compared to deep soils, the sampled surface soils are enriched in OrgC, N, P, Cd, S，Hg, Ag, B, Au, S and poor with As, Ni, I, Co, Cr, V, MgO, Sc, Al2O3, Fe2O3？etc. The characteristics of geochemical reference value of element in soil that inherited soil parent material and regional elements combined features reflected that the elements enriched in the soil was interrelated with acid rock, sandstone and shale. The spatial distribution characteristics of element regional geochemistry were conditional by regional environmental geological conditions，and effected by human activities. The Pearl River Delta plain is a typical geochemical landscape area with regional anomaly of multiple-elements. The north, western and eastern parts of the Pearl River

Tingting Li, Xiaoming Liu
Psychology (PSYCH) , 2016, DOI: 10.4236/psych.2016.71007
Abstract: Background: Character strengths are important psychology resources, which affect the academic and social development of students at secondary vocational schools. Purpose: We aimed to clarify the relationship between character strengths, psychological stress, and psychological symptoms among these students from a positive psychological perspective. By focusing on virtues and strengths, we suggest improvements to school education and family upbringing. Sample: A total of 282 secondary vocational school students were recruited. Design and Method: Students were asked to complete the Chinese Virtues Questionnaire, Life Stress Rating Scale, and Symptom Checklist-90. Statistical analyses were conducted using SPSS 19.0. Results: Regression analyses indicated that the interaction between relationship strengths and family stress explained 45% of the variance in psychological symptoms. This study clarified the positive role of character strengths in stressful situations. Thus, helping secondary vocational school students recognize and use their strengths is conducive to improving their health. Conclusion: Our results should also help teachers and parents adopt a strengths perspective, which might encourage students to explore and develop their strengths.

Abstract:
本文就国家现有的光伏扶贫模式进行了比较分析，详细阐述了各方主体所关心的问题。为了使扶贫更加精准，项目更加具有可持续性和利益共生性，笔者提出了一种新的扶贫模式，即“1 + 2 + 4”，以基金为一个中心，全面、详细阐述了基金的“来龙去脉”；以增加农民受益，扩大电力需求为两个基本原则；就近发电、就近并网、就近转换、就近使用为四个基本点。最终，确保政府的扶贫目标得以实现，农民的收入得到保证，企业的投资得以有效地收回，银行的担保得以相对地降低风险，整个农网线路的改造得以完成，弃光现象得以缓解，让扶贫之路的前景充满了一片光明。
The present models of poverty alleviation in China have been compared and analyzed in the article. Also, the questions that all parties concern have been elaborated. To take targeted measures in poverty alleviation, to make the program sustainable and multi-beneficiary, I come up with a new model based on the present patterns project the “1 + 2 + 4”. “1”means that the central point of poverty alleviation project is establishing a fund, whose ins and outs are illustrated thoroughly and carefully. “2” means that the two principles are to raise peasant’s income and to expand electricity demand. “4” means that the four basic points are to generate electric power nearby, to interconnect electricity nearby, to convert electricity nearby, to use electricity nearby. When all the things talked above can be taken account seriously, the governmental goal of poverty alleviation, the long-lasting income of famers, the paid-off investment of enterprise, the lower risk of bank’s guarantee and the rural electric network alteration are only matters of time.
亲缘利他的不对称性：进化视角的分析
王瑞乐,刘涵慧,张孝义
心理科学进展 , 2012,
Abstract: 内含适应性理论是进化生物学和进化心理学中最重要的理论之一。该理论假设, 个体的亲属是其适应性的载体, 但亲属们的价值有所不同。大量研究发现, 亲属的利他行为表现出不对称性, 即遗传相关系数相同的亲属表现出不同的利他倾向。如祖父母对孙辈的投资中, 外祖母往往投入最多, 外祖父和祖母次之, 祖父投入最少。研究者用内含适应性理论来解释这种亲缘利他差异, 进而提出了“父亲身份不确定性”等具体的进化假设。未来研究中, 国内研究者应在正确理解内含适应性理论的基础上, 更多关注亲缘利他的不对称性, 采用多种数据采集方法和统一的评定指标。

Juntao Li, Tingting Dong, Meng Li
Social Networking (SN) , 2016, DOI: 10.4236/sn.2016.52008
Abstract: During the diffusion of information on the network, the users generally have such an experience that at the beginning they get aware of the news they never know and may be willing to inform others, then their interests fade away, finally the information stops flowing. Meantime, their points of view are changing as the networks’ structure changes. Therefore, this article brings in the interest attenuation mechanism and the social networks consensus evolution mechanism on the basic of the improved SEIR model. So to begin with, we establish a model to analyze how users’ interests change during the diffusion of information on the network. Second we establish another model to analyze the evolution of the opinion during the diffusion of information on the network. At last, we establish a final model by using dynamic equations adding the results of the two models above.
