昆山市耕地变化和粮食安全研究

采用粮食自给率结合区域最小人均耕地面积对江苏省昆山市20多年来粮食安全状况进行研究,结果表明:昆山市在2000年从粮食产区转型为粮食销区;2006年的粮食自给率仅有23%;生产力提高和作物种植结构的相互制约导致了最小人均耕地面积呈波动变化。在粮食安全未来发展趋势的分析方面,提出了依据相关社会经济指标对昆山市发展阶段进行聚类分析,然后以最新发展阶段数据进行建模的新思路。分析结果表明:昆山的粮食安全相关的社会经济指标变化确实呈明显阶段性;至2011年,昆山市粮食自给率将下降至11%;最小人均耕地面积降低至0.028 hm2,如果该变化趋势得不到有效控制而持续较长时间,到2016年时,粮食自给率和最小人均耕地面积将分别下降至8%和0.012 hm2。依据这些分析及预测,文章提出了坚持土地集约利用、提升耕地生产力、建立和完善粮食流通网络和拓展并强化与粮食产区之间的合作等保障粮食安全、促进地区可持续发展的对策措施。     

Minimization of socioeconomic disruption for displaced populations following disasters

In the aftermath of catastrophic natural disasters such as hurricanes, tsunamis and earthquakes, emergency management agencies come under intense pressure to provide temporary housing to address the large‐scale displacement of the vulnerable population. Temporary housing is essential to enable displaced families to reestablish their normal daily activities until permanent housing solutions can be provided. Temporary housing decisions, however, have often been criticized for their failure to fulfil the socioeconomic needs of the displaced families within acceptable budgets. This paper presents the development of (1) socioeconomic disruption metrics that are capable of quantifying the socioeconomic impacts of temporary housing decisions on displaced populations; and (2) a robust multi‐objective optimization model for temporary housing that is capable of simultaneously minimizing socioeconomic disruptions and public expenditures in an effective and efficient manner. A large‐scale application example is optimized to illustrate the use of the model and demonstrate its capabilities ingenerating optimal plans for realistic temporary housing problems.     

Analysis on the Evolution of Regional Economic Disparity in the West Coast of the Strait

With the implementation of reform and opening-up, the overall economy of China has made brilliant achievements; meanwhile, however, the economic disparity has been enlarging among some regions, and between the city and the countryside. The existence and evolution of this kind of economic disparity is concerned with social stability, sustainable development and the construction of harmonious society, which has gradually become the hotspot in social economic development. The West Coast of the Strait （WCS） located in southeast littoral areas is adjacent to the Pearl and Yangtze River Delta in the south and north and faces Taiwan Province in the east. The stability and development of this region has vital political and economic meaning in the social economic development of our country. It has important theoretical meaning and practical value to research the form, characteristics and evolution of regional economic disparity in the WCS. Based on insightful analysis on existing study results on the WCS, the paper defines the connotation and extension. By a series of absolute and comparative relative evaluation indexes and taking the WCS since 1992 as the study object, the paper makes analysis on different scales including three regions, four regions, 20 cities and 152 counties, quantitatively evaluates the level, characteristics and evolution of the regional economic disparity and compares the regional economic disparity on different scales. The main conclusions are as follows： the variation trend of the absolute disparity of the whole region is obvious and stable, which has presented an inflating trend; the comparative variation trend on a large scale has waved, The comparative disparity of the three regions increased annually from 1992 to around 2000, which had a decreasing trend from around 2000 to 2005; the comparative variation trend on a small scale was not stable, which showed an annual increase of four regions, 20 cities and 152 counties from 1992 to around 2003 and a decrease from around 2003 to 2005; the     

中国西北地区水资源的开发和利用

我国西北地区地广人稀,水资源比较贫乏,而且时空分布极不均匀,极大地影响了该地区人民的生活,限制了该地区的经济开发,因此大力开发西北地区面临的首要问题即水资源问题。本文从西北地区水资源的自然分布、开发利用水资源中存在的问题及有效的解决途径三方面进行了简要的综述。     

风险社会中突发事件的特征与处置理念探析

突发性事件由于其本身所具有突发性、紧急性、危重性、复杂性、关联性、广泛性、政治性和不确定性等特征,所以其负面性影响很大,往往可能成为激发社会矛盾、进而爆发政治、经济和社会危机的直接原因。而经济转轨、社会转型、利益群体多元化等许多不稳定的因素,对局部地区乃至全国的经济发展和社会稳定构成了潜在威胁。在这样一个具有诸多风险因素的社会,由此而引发的突发事件又有形式多元化、规模扩大化、形态群体化、影响辐射化、目标国际化等特点。所以,在现阶段,处置突发事件的理念必须适应这种风险社会的公共危机特点,做到危机缓和,未病先防;以人为本,取信于民;利益调和,治病求本。     

The role of symbolic capital in stakeholder disputes: decision-making concerning intractable wastes

This paper examines almost 30 years of disputation concerning the disposal of the world's largest stockpile of the toxic organochlorine, hexachlorbenzene. It describes the study of a chemicals company in its attempt to manage the disposal of the toxic waste in a collaborative fashion with government, environmentalists and the local community. The study describes the new processes and structures specifically designed to address the decision-making and the issues of stakeholder perception and identity construction which have influenced the outcomes. Decision-making in such disputes is often theorized from the perspective of the emergence of highly individualized and reflexive risk communities and changing modes and expectations of corporate responsibility as a result of detraditionalization. We argue that the stakeholder interaction in this study reflects competing discourses in which corporate actors prioritize the building and maintaining of identity and symbolic capital rather than an active collaboration to solve the ongoing issue of the waste. As well, issues of access to expert knowledge highlight the relationship between conditions of uncertainty, technoscientific expertise and identity. The events of the study highlight the challenges faced by contemporary technoscientific corporations such as chemicals companies as they must deliver on requirements of transparency and openness, while maintaining technoscientific capacity and strong internal identity. We conclude that the study demonstrates the co-existence of social processes of individualization and detraditionalization with quasi-traditions which maintain authority, thus challenging the radical distinctions made in the literature between modernity and late or reflexive modernity.     

The pathway to a sustainable industrial society – initiative of the Research Institute for Sustainability Science (RISS) at Osaka University

While it is widely known that sustainable development is the only sound and viable pathway for humankind’s future, its attainment remains elusive despite intensive efforts and some successes. The current industrial society approach based on product and process innovation in a variety of fields is not providing the expected results in addressing this important issue. In an attempt to carry out this unavoidable task, Osaka University’s Research Institute for Sustainability Science (RISS) introduces an integral and dynamic innovation system where technology plays a key role in fulfilling societal functions. This innovation system adopts a highly solution-driven approach that makes use of backcasting techniques based on long-term visions and mid-term strategic goals. Since technology management is the key to propelling effective innovation towards sustainability, we propose a technology transition management through the interaction of technology push, demand pull and institutional design, along with eight transition principles. RISS will develop this innovation system based on these three components and through the design of dynamic scenarios and their roadmaps.
