关于实行农地信托促进农地健康流转的思考

河北省农业正进入由传统农业向现代农业转变的新时期。现代农业要求土地集约和规模经营,进行土地流转是实现土地集约和规模经营的有效途径之一。在维护农村土地承包关系稳定的基础上,积极探索有效的农地流转模式是党和政府在农村土地问题上的一贯方针。借鉴别国模式,结合我国实践,进行模式创新,可以多方位促进农地流转健康发展。农地信托流转模式既是土地制度的创新,又是经营体制的创新,符合新时期农村先进生产力的发展方向和要求,有利于促进农业的规模经营和集约经营,有利于土地资源资本化,形成多元、长期的农业投入机制。     

城市肌理的传承与更新——河西古镇开发中街道空间的延续

城市肌理是随着人类社会历史的发展而逐步演化的产物,是一个城市人文记忆和历史信息的载体,如何在城市肌理中延续城市的历史文脉,解读城市的人文记忆,构筑城市的美好未来,必然成为城市发展的重中之重。在河西古镇开发中如何保护原有城市肌理,延续城市的历史文脉,做到保护城市的历史信息和风貌特征的同时,又能改善人居环境,使新的城市肌理能够"有机切入"原有肌理,成为一个必须重视的现实问题。

Consumer demand for healthy eating considering diversity – an economic approach for German individuals

Rising incidence and costs of diet‐related diseases have led to nutritionists' and economists' interest in factors determining the demand for healthy eating. The present study analyses the demand for healthy eating by the use of a new food‐based indicator, which combines the health value and diversity of a food basket. Although the diversity aspect gains in importance in recommendations for healthy eating it was not considered adequately in healthy eating indicators until now. Within the household production theory the new indicator is used to identify factors influencing the demand for healthy food diversity for 3220 German individuals. The results of regression analyses show that the demand for a healthy diet is influenced by age and mainly by knowledge, attitudinal and behavioural (proxy‐)variables as education level, participation in a health training course and sport activity. On the basis of these findings conclusions are drawn for health and nutrition policy in Germany and Europe.

Impacts of urban renewal on the place identity of local residents – a case study of Sunwenxilu traditional commercial street in Zhongshan City,Guangdong Province,China

ABSTRACT

This paper studies the impacts of urban renewal on local residents’ place identity by examining the changes in local residents’ place identity in Sunwenxilu, a traditional commercial street in downtown Zhongshan City, Guangdong Province, China, which carried out urban renewal relatively early in modern China. Applying Breakwell’s [(2015). Risk: Social psychological perspectives. In J. D. Wright (Ed.), International encyclopedia of the social & behavioral sciences (2nd Ed.). New York, NY: Elsevier] identity process model and using the renewal process as a starting point, data concerning local residents’ place identity in Sunwenxilu were collected through in-depth interviews, observations, and literature analysis. The results reveal that local residents had established a strong place identity on Sunwenxilu before it changed to be a community of “incompetents” in the 1990s. In the late 1990s, Sunwenxilu was transformed into a cultural tourism pedestrian street. Right after the transformation, local residents regained their self-esteem with the improvement of the physical environment and intensification of cultural symbols, and re-established their place continuity by maintaining their collective memories. However, a failure to improve the local residents’ self-efficiency of place during the “superficial” renewal had resulted in vulnerability of the local residents’ place identity in terms of self-esteem, continuity and distinctiveness, thus causing another crisis of place identity. Obviously, the construction of place identity results from the interaction of all elements, so too much emphasis on only one element may trigger a new identity crisis.     

The influence of attitudes towards healthy eating on food consumption when travelling

This study explores tourists' attitude towards healthy eating and its influence on their travel eating behaviour. Based on focus group interviews and literature review, two instruments were developed to measure healthy eating attitude and travel eating behaviour. Factor analysis results revealed two healthy eating attitude factors (‘food content and nutrients’ and ‘balanced diet and eating habit’), and five travel eating behaviour factors (‘novelty’, ‘risk avoidance’, ‘health steadfastness’, ‘familiarity’, and ‘food supplement and medicine’). The relationships among the factors were examined using structural equation modelling. The findings revealed that respondents who had a stronger attitude towards ‘balanced diet and eating habit’ tended to be more motivated by the ‘novelty’ factor; whereas ‘risk avoidance’, ‘health steadfastness’ and ‘familiarity’ were found to be associated with a stronger attitude towards ‘food content and nutrient’. The findings suggest that the healthy eating attitude construct is multidimensional and healthy eating conscious tourists should not be treated as a homogeneous group.     

职场友谊对研发团队创新绩效的影响机制研究——一个带中介的调节模型

本文通过问卷调查法获得372份有效问卷,运用带中介的调节模型探讨了职场友谊对研发团队创新绩效的影响机制。实证结果表明：（1）职场友谊对团队创新绩效是有正向的激励作用的,其中知识分享起中介作用;（2）职场友谊对团队创新绩效的作用同时受到员工知识分享意愿和知识分享能力的中介作用;（3）职位级别对职场友谊通过知识分享对团队创新绩效的影响起负向调节作用,即职位级别越高,友谊机会越小,通过员工友谊促进知识分享,进而提高团队创新绩效的效应越低。     

历史街区型购物场所顾客满意度研究——广州状元坊案例

尽管顾客满意度研究在相关领域已是一个研究颇久的话题,但在历史街区相关研究中鲜有涉及.本研究结合历史街区型商业街(广州状元坊)的特点,对ACSI(美国顾客满意度指数)模型加以引中和改进,构建新的适合商业街的顾客满意度评价体系,并通过问卷数据收集,采用李克特量表法,定量化地对状元坊的顾客满意度进行了实证研究.研究结论显示,顾客对状元坊的总体满意度一般;环境质量感知普遍较差,商品价格和商品种类满意度较高;学生是状元坊的主要消费群体;而区位优势、特有消费群体与准确的市场定位对状元坊顾客重游率具有决定作用.研究对拓展国内目前还比较薄弱的历史街区型商业街满意度研究有积极意义,研究结论可为商业街可持续发展提供指导作用.
