川西高原典型作物土地适宜性评价及其影响因素

目的 川西高原生态环境脆弱,经济发展水平低,开展生态脆弱区域典型作物土地适宜性分析,对农业生产的作物规划管理,以及拓宽当地农户增收致富渠道具有重要意义。方法 文章基于四川省土地利用现状数据,综合运用AHP层次分析法、栅格指数模型,构建川西高原典型作物土地适宜性目标层、准则层和指标层三级评价指标体系。结果 （1）典型作物土地适宜性评价因子中气候条件影响较大,社会经济条件影响相对较小。（2）大白菜种植适宜用地主要分布在大渡河中游和岷江流域,其中高适宜区1.652 5 万hm²;苹果种植适宜用地主要分布在大渡河流域河谷山地和岷山山脉,其中高适宜区36.121 5万 hm²;梨种植适宜用地主要分布在大渡河中游和岷江流域,其中高适宜区31.025 3万hm²;甜樱桃种植适宜用地主要分布在大渡河和岷江流域的河谷和山地,其中高适宜区16.891 4万hm²;核桃种植适宜用地主要分布金沙江、雅砻江、大渡河和岷江流域的河谷区,其中高适宜区41.913 7万hm²。（3）从县域空间尺度上评价,川西高原推荐种植核桃和梨的县（市）最多,分别为22个和16个。推荐种植大白菜的县（市）最少,只有3个。（4）川西高原农业产业光温条件好、气候垂直变化显著,但常受低温等极端天气影响;耕地比重小、分布零散且耕地质量低;低纬度高海拔同时地势高耸、地形破碎;交通和灌溉设施薄弱,自然—社会经济因素影响川西高原典型作物产业发展。结论 研究结果符合川西高原典型作物种植现状,但是该研究构建的土地适宜性评价体系中对内源性因素考虑不够,缺乏对劳动力、经营方式等因素的分析,同时缺少对科学技术、法律法规、政策、市场等外源性因素的思考。

Tourist experience of nature in contemporary China: a cultural divergence approach

The study of Chinese nature tourism is a relatively independent research realm which adopts a cultural perspective to study the tourist experience. Chinese tourists are regarded as being accustomed to experiencing nature through associating it with high culture such as landscape poetry and paintings, calligraphy, and so on, and the impacts of traditional popular culture are seldom addressed. Yet, for the majority of Chinese, popular culture has significant influences on their behavior. From a cultural divergence approach, this paper chooses Huangshan Mountain as a case to investigate the way common Chinese people experience nature, and it is found that cultural impacts are differentiated, since neither cultures nor tourist groups are homogeneous. Specifically, tourists can be classified into classicists and folklorists according to whether they have professional knowledge about the traditional arts. As the majority of Chinese are folklorists and are largely neglected in the research, they are the main interest of this study. High culture has a weak impact on folklorists because they lack professional knowledge to associate with nature through high culture. It is popular culture that strongly influences folklorists’ behaviors in their drawing farfetched analogies to nature and praying to nature.     

Why is there no momentum in the Taiwan stock market?

Momentum strategies usually do not produce significant profits in emerging stock markets. Chui, Titman, and Wei [Chui, A. C. W., Titman, S., & Wei, K. C. J. (2000). Momentum, legal systems and ownership structure: An analysis of Asian stock markets. Working paper, Hong Kong Polytechnic University, Chui, A. C. W., Titman, S., & Wei, K. C. J. (2006). Individualism and momentum around the World. Working Paper, Hong Kong Polytechnic University] argue that the lack of profitability is due to cultural differences. In this paper, we look at one of the largest emerging markets, the Taiwan stock market. We find that DOWN markets occur more frequently and momentum profits are more negative following DOWN markets in Taiwan than in the US. Taken together, our findings suggest that the lack of profits from momentum strategies in emerging markets may be due more to the state-dependence of momentum discovered by Cooper, Gutierrez, and Hameed [Cooper, M. J., Gutierrez R. C., & Hameed, A. (2004). Market states and momentum. Journal of Finance, 59, 1345–1365] rather than to cultural differences.     

信托业洗钱风险分析及反洗钱对策

信托业面临的洗钱风险主要在于被利用实现非法资金的离析和融合，隐瞒资金的真实来源和去向，将犯罪收益融入一般经济体系。当前信托业反洗钱面临信托行业反洗钱基础薄弱、信托业反洗钱制度建设亟待完善、信托业反洗钱监管相对滞后等问题，必须完善制度体系建设，增强信托合规经营意识，健全内部控制措施，全面落实反洗钱要求，切实防范信托业被洗钱毒瘤侵蚀。

Simultaneous dock assignment and sequencing of inbound trucks under a fixed outbound truck schedule in multi-door cross docking operations

This paper studies the simultaneous dock assignment and sequencing of inbound trucks for a multi-door cross docking operation with the objective to minimize total weighted tardiness, under a fixed outbound truck departure schedule. The problem is newly formulated and solved by six different metaheuristic algorithms, which include simulated annealing, tabu search, ant colony optimization, differential evolution, and two hybrid differential-evolution algorithms. To evaluate the total weighted tardiness associated with any given inbound-truck sequence and dock assignment, an operational policy is developed. This policy is employed by every metaheuristic algorithm in searching for the optimal dock assignment and sequence. Each metaheuristic algorithm is tested with 40 problems. The major conclusions are: (1) metaheuristic is generally an effective optimization method for the subject problem; (2) population based metaheuristic algorithms are generally more effective than projection based metaheuristic algorithms; (3) proper selection of algorithmic parameters is important and more critical for projection based metaheuristic algorithms than population based algorithms; (4) the two best algorithms are ant colony optimization and hybrid differential evolution 2; among them, ACO takes less time than hybrid 2 and thus can be declared the best among all the six metaheuristic algorithms tested.

Consumer evaluation of self-service innovation failure: the effect of brand equity and attribution

The purpose of this study is to examine how, when a self-service innovation fails, customers evaluate different levels of brand equity and how the brand equity effect is moderated by consumer attribution and service recovery. Based on two experimental studies, the results indicate that high-equity brands suffer less from the adverse effects of self-service innovation failures when compared with low-equity brands. However, self-service innovation failures are more detrimental to high-equity brands if they are caused by service providers' internal factors as well as low service recovery.
