Production function for wheat: a case study of Southeastern Anatolian Project (SAP) region

Functions for total wheat production, the major agricultural crop of Gaziantep, Sanliurfa, Diyarbakir, and Mardin provinces in Southeastern Anatolian Project (SAP) region in Turkey were developed by using annual data lor the 1963-1989 period. Regression analyses were carried out on the multiple-linear, quadratic, and Cobb-Douglas functional forms of total wheat production in the region effected by cultivation area, fertilizer usage, and rainfall. From the economical theories' point of view the model revealed good insight. The models were statistically significant at the 95% confidence level. Irrigation is valued quite substantially. Output elasticities of inputs are less than 1 and function coefficient is elastic. Thus input employment can be increased to increase wheat production. Further research based on factor analysis is recommended.     

森林旅游景区旅游规划模式研究—基于休闲旅游的视角

休闲旅游驱动森林旅游景区旅游规划模式演进。“三析五构”旅游规划模式注重社会发展导向,包括旅游环境分析、旅游资源评析和休闲旅游市场分析的“三维一体”系统评析,以及包含旅游规划理念体系、旅游规划目标体系、旅游功能区划体系、休闲旅游产品体系和旅游支持体系的“五位一体”体系构建。以南京牛首山森林公园为例对此模式进行了实证研究。     

干部教育培训中对学员需求的尊重、服务与引导

在干部教育培训中尊重、服务、引导学员需求,是深入贯彻落实科学发展观和以人为本原则的根本要求。对西方公务员培训理论和做法,要注意结合国内干部培训实际,认清规范与转化的双重任务。由于目前学员需求在表达、汇总、分析上的历时性。要进一步明确和把握学员需求表达在场合、渠道和形式上的多样化特点,坚持动态把握、整体响应、差异服务、精细操作等原则。建立进校前的学员需求分析制度、在校时的学员历时性需求汇总反馈制度、离校后的学员需求跟踪制度。对学员需求,一方面要切实尊重、有效服务。另一方面要辩证分析、积极引导,使其统一于“以人为本,按需施教”的培训全过程。

“海上丝绸之路”沿线国家地缘脆弱性时空演变及影响因素分析

"海上丝绸之路"倡议将对世界政治经济格局产生深远影响,其推进势必伴随着中国权力半径的延伸和承受沿线国家地缘政治风险的阻碍,沿线国家地缘脆弱性成为影响倡议顺利推进的关键前提。从脆弱性视角出发,界定地缘脆弱性内涵,以敏感性—应对能力作为地缘脆弱性评估框架,基于综合指数法、空间探索性方法和ArcGIS可视化手段,利用GDELT中海量事件数据和沿线国家统计数据,测度2000-2017年"海上丝路"沿线海洋国家地缘脆弱性时空演变特征,探索地缘脆弱性演变的影响因素和内在机制。结果表明:①时间序列上,沿线区域地缘脆弱性波幅较大,不同板块差异显著;空间演变上,脆弱性高的国家数量先升后降,空间格局基本保持稳定。②三项指数均存在集聚性和区域差异性,且体现出地缘政治风险高和地缘影响力大的区域在空间上重叠的"悖论"。③地缘脆弱性演变的影响因素为地缘政治风险和地缘影响力;内在驱动力涉及地缘区位、地缘政治和地缘经济。     

Preference aggregation and repeat buying in households

Marketing researchers have long used brand switching analyses and Markov transition matrices to gain insights into managerial problems. Almost without exception, this work makes (inappropriate) inferences about individual consumers by analyzing household-level data. This paper presents a procedure based on the distribution of run lengths in household level panel data that allows more insights into the choice behavior of the individuals in the household. We test these procedures in a large simulation study by attempting to recover the underlying (known) structure of the process generating a string of panel data. Finally, we use the procedure to classify the purchase behavior, with respect to powdered soft drinks, of a set of households in a panel. Our results show that marketing scientists have the potential to learn and test more hypotheses about the individuals in a household by examining the distribution of run lengths.We gratefully acknowledge Professor Bari Harlam of the University of Rhode Island for providing the panel data.     

Exploring spatio-temporal changes of city inbound tourism flow: The case of Shanghai,China

Knowledge on spatio-temporal changes of inbound tourism flow is important for destination economy, cultural communication and city image. This paper proposes a novel research framework for the spatio-temporal distribution and changes of inbound tourism flow by, first, using R-HDBSCAN clustering algorithm to extract tourism area of interest (AOI), second, by utilizing several key indicators adopted from the complex network theory literature to study the structure of inbound tourism flow with a case study example from Shanghai, China. The results show, first, that tourism in Shanghai is highly concentrated on the most popular AOI clustered in the city center relatively close to each other and, second, that, the inbound tourism flow network of Shanghai has small-world characteristics, while the distribution of its AOI (nodes) and tourist routes (edges) has general power law features, which has been influenced by the World Expo.

中日绿色建筑发展的对比研究

日本的绿色建筑建设先于我国,有许多可借鉴之处。本文首先对比了中日经济发展、建筑业发展、建筑能耗等与建筑相关的基本国情。分析得知：两国经济处在不同的发展阶段,国情不同;1996-2008年,中国各类建筑面积增长了74.5%,而日本减少了56.2%;2007年与1996年相比,中国的单位面积公共建筑能耗增加了20%,而日本减少4.41%。进而,重点分析了中日绿色建筑发展的历程、绿色建筑的定义及内涵、评价标准等方面的异同。认为：日本绿色建筑的建设起步较早,但我国的发展速度很快;两国绿色建筑的定义描述虽有些不同,但内涵基本一致;评价标准的种类存在差异,评价内容相近,评分方法、定级方式、表示方式有所不同。最后,根据中国国情,提出了加强宣传普及工作、提高全民意识和公众认知度、加大激励政策力度等借鉴日本成功经验的几点建议,以期对我国推进绿色建筑的发展有所帮助。
