Spatial and Temporal Variability of Farm Size in China in Context of Rapid Urbanization

引用

Chinese Geographical Science 2013年第5期23卷 607-619页

作者： TAN minghong guy m robinson LI Xiubin XIN Liangjie Institute of Geographic Sciences and Natural Resources Research Chinese Academy of Sciences Centre for Rural Health&Community Development University of South Australia

During the last 30 years, China has witnessed rapid economic growth and dramatic urbanization, with about 1.2 x 107 rural people migrating annually into urban areas. meanwhile, especially since 1995, the rural population has been declining, which is closely linked to land circulation and the increase in farm size in many villages. Increasing scale of farming operations is often regarded as a key to avoiding the abandonment of farmland and to increasing the income of rural farmers. However, until now, there has been little research on the spatial and temporal variability of farm size at the national level in China. Using data from the national agricultural cen- sus and rural household surveys, this study examines the characteristics of land use circulation and the consequent changes in the area of farmland per household. The results show that： 1） 12.2% of rural households were involved in land circulation at the national level. The highest amounts of land circulation have occurred in those provinces where the farmland per capita is more than 0.2 ha or less than 0.1 ha; 2） over 80% of households operate less than 0.6 ha of farmland; 3） the proportion of mid-sized farms （between 0.2 ha and 0.6 ha per household） has decreased while the smallest and the largest farms have increased. This bears some similarity with the phenomenon known as the ＇disappearing middle＇, referring to the changes in farm size. This study establishes a framework for interpreting the factors affecting the changes in farm size in China, which include two promoting factors （urbanization and agriculture） and four hindering fac- tors （agricultual land system, household registration, stable clan system, and farmland loss）.

Rural transformation:Cherry growing on the Guanzhong Plain, China and the Adelaide Hills, South Australia

引用

Journal of Geographical Sciences 2019年第5期29卷 675-701页

作者： guy m.robinson 宋冰洁 Department of Geography Environment and Population University of Adelaide School of Geography and Tourism Shaanxi Normal University

This paper echoes a tradition in agricultural geography by focusing on a single crop:cherries. It illustrates how developments associated with globalisation and growing urban markets are re-shaping rural areas. The interplay between global and local is investigated in two different contexts. A Chinese example reflects transformations affecting the countryside following national economic reforms. Focusing on the hinterland of Xi'an, capital of Shaanxi Province, it examines farmers' responses to the changing socio-political context and the rising size and wealth of the local market. Individual initiatives backed by government support have spawned localised concentrations of cherry growing and increased horticultural ***-based tourism is creating new relationships between farmers and consumers, with farms becoming more diversified and multifunctional. The second example is the Adelaide Hills, South Australia, where cherry growing is increasingly combined with direct sales to consumers and gastronomic tourism. The paper addresses contrasts and similarities between the two examples in the interplay between global and local, and a ‘multifunctional transition' in farming. Concluding remarks include reference to new economic links forged between China and Australia through relaxations on cherry imports to China and new patterns of Chinese foreign direct investment into Australian cherry production. A research agenda for future research is suggested.

Urban spatial development and land use in Beijing： Implications from London＇s experiences

Journal of Geographical Sciences 2011年第1期21卷 49-64页

作者： TAN minghong guy m. robinson LI Xiubin Institute of Geographic Science and Natural Resources Research CAS Beijing 100101 China Centre for Rural Health & Community Development University of South Australia 111 Nicolson Avenue Whyalla Norrie South Australia 5608 Australia

Beijing is facing a huge challenge to manage the growth of its built-up area whilst also retaining both productive arable land and land for conservation purposes in order to simultaneously realize the three aims of economic development,protecting arable land and generating environmental improvements. meanwhile,London,as a world city with more than 200 years of industrialization and urbanization,has accumulated rich theoretical and practical experiences for land use planning in a major urban area,such as the creation of Garden Cities,a designated Green Belt and New Towns. This paper firstly analyzes the main characteristics of the spatial distribution of the built-up area,arable land and conservation land in Beijing. Then,some of the key aspects of urban fringe planning in the London region are examined. Lastly,several implications from the experience of London are provided with respect to land-use planning for Beijing,concentrating on a re-appraisal of land-use functions around Beijing,measures to improve the green belt,the development of small towns to house rural-urban migrants and urban overspill,and effective implementation of land-use planning.

INVARIANCE AND STABILITY OF THE PROFILE EQUATIONS OF GEOmETRIC OPTICS

引用

Acta mathematica Scientia 2011年第6期31卷 2141-2158页

作者： guy mtivier Jeffrey Rauch Institut de mathmatiques de Bordeaux Universit de Bordeaux Department of mathematics University of Michigan

The profile equations of geometric optics are described in a form invariant under the natural transformations of first order systems of partial differential equations. This allows us to prove that various strategies for computing profile equations are equivalent. We prove that if L generates an evolution on L2 the same is true of the profile equations. We prove that the characteristic polynomial of the profile equations is the localization of the characteristic polynomial of the background operator at （y, dφ（y）） where φ is the background phase. We prove that the propagation cones of the profile equations are subsets of the propagation cones of the background operator.

Genetics in medical school curriculum:A look at the University of Rochester School of medicine and Dentistry

引用

Journal of Zhejiang University-Science B(Biomedicine & Biotechnology) 2008年第1期9卷 10-15页

作者： Deanne m. robinson Chin-To FONG Department of Pediatrics University of Rochester School of Medicine and DentistryRochesterNY 14642USA

Genetics is assuming an increasingly important role in medicine. As a result,the teaching of genetics should also be increased proportionally to ensure that future physicians will be able to take advantage of the new genetic technology,and to understand the associated ethical,legal and social issues. At the University of Rochester School of medicine and Dentistry,we have been able to incorporate genetic education into a four-year medical curriculum in a fully integrated fashion. This model may serve as a template for other medical curriculum still in development.

Association between thyroid function and gallstone disease

引用

World Journal of Gastroenterology 2005年第35期11卷 5530-5534页

作者： Henry Vlzke Daniel m robinson Ulrich John Ernst moritz Arndt University Greifswald Institute of Epidemiology and Social medicine Walther Rathenau Str. 48 D-17487 Greifswald Germany Ernst moritz Arndt University Greifswald Department of medicine B Friedrich Loeffler Str. 23a D-17487 Greifswald Germany

AIm： To investigate those associations using data of the population-based Study of Health in Pomerania. mETHODS： A study population of 3 749 residents aged 20-79 years without previously diagnosed thyroid disease was available for analyses. Serum TSH was used to assess thyroid function. Cholelithiasis was defined by either a prior history of cholecystectomy or the presence of gallstones on ultrasound. Logistic regression was performed to analyze independent associations between thyroid function and cholelithiasis. RESULTS： There were 385 persons （10.3%） with low （〈0.3 mIU/L）, 3 321 persons （88.6%） with normal and 43 persons （1.2%） with high serum TSH levels （〉3 mIU/L）. The proportion of cholelithiasis among males and females was 14.4% and 25.3%, respectively. Among males, there was an independent relation between high serum TSH and cholelithiasis （OR 3.77; 95%-CI 1.06-13.41; P〈0.05）. Also among males, there was a tendency towards an elevated risk of cholelithiasis in persons with low serum TSH （OR 1.40; 95%-CI 0.96-2.02; P= 0.07）. In the female population, no such relation was identified. CONCLUSION： There is an association between thyroid and gallstone disease with a gender-specific relation between hypothyroidism and cholelithiasis.

Aristotle, the Intellect, and Cognition

引用

Frontiers of Philosophy in China 2014年第2期9卷 229-240页

作者： Thomas m. robinson Department of Philosophy University of Toronto Toronto Ontario M5R 2M8 Canada

It is argued in this paper that the famous ＂Active Intellect＂ of De Anima 3.5 is not God, as Alexander of Aphrodisias held, but rather an unchanging, eternally cognizing Intellect which serves as the indispensable condition for the operation of human intellect. It is ＂at the door＂ for each individual, ready to flow in as a stream of light--a light which renders potential objects of cognition knowable, just as visible light makes potentially visible objects visible--from outside that door （thyrathen） any time it is opened. Its existence cannot serve, however, as a proof of the immortality of human intellect, since, being unchanging, it can never possess a feature of human intellect which is characterized by nothing if not change, and that is memory.
