It's good to talk: performing and recording the telephone interview

This paper explores the transition of talk to text in the process of performing and recording semi-structured interviews over the telephone. In particular, it considers the ways respondents and the materials enjoined in the process of interviewing exceed their role in the research process. Drawing on my experience of conducting telephone interviews in the UK, I position the interview as an uncertain encounter: one framed by earlier narrations as much as the aims and objectives of the research project; and an orientation towards 'talk' as much as the reduction of performance to text. Far from losing track of these uncertainties I argue that tape-recorders are well equipped to document these in/audible realms.     

转型期广州市居住迁移的分阶段比较

将住房制度改革划分为起步、房改售房和住房市场化3个阶段,利用大规模的入户调查资料,分析不同阶段城市居民的居住迁移影响因素差异.研究发现,住房制度改革以来广州市年均居住迁移率呈波动上升趋势,1998年货币分房政策的实施引发大规模的居住迁移,导致城市空间大规模重构;利用事件史分析方法分析发现家庭生命周期、工作单位变动、住房产权和住房性质选择等都显著影响居住迁移,但不同阶段其作用机制和影响程度存在明显差异.起步阶段的居住迁移仍是制度安排下的被动迁移;市场化阶段的居住迁移自发性增强;房改售房阶段两种体制并存,居住迁移行为相对更复杂.随着住房市场化程度的进一步增强,家庭生命周期因素和社会经济地位的变化对居住迁移的影响将会增强.     

基于投入产出技术的中国部门生产链平均能耗

温室气体导致全球气候异常变化是全球目前的热点问题,而能源消耗排放的CO2成为首要的温室气体。为理解产业结构对我国能源消耗及其碳排放的影响机制,本文创建了一个基于投入产出技术的AECPC模型,提出了平均能耗的概念。该模型从节能效果直接且易于调控的角度反映了不同层次的生产环节对部门生产链能耗的影响,它综合了直接能耗和完全能耗两种方法的优点。通过该模型对中国2005年各产业部门的测算,找出了9条不同能源产品平均能耗最大的生产链,这些生产链主要集中在传统的高能耗部门,但也包含一些其他部门,如自来水的生产与供应业部门。AECPC模型为产业转型对碳排放的影响提供了有力的分析指导工具。     

<Emphasis Type="Italic">In vitro</Emphasis> iron enrichment experiments in the Prydz Bay,the Southern Ocean: A test of the iron hypothesis

In "high nitrate, low chlorophyll" (HNLC) ocean regions, iron has been typically regarded as the limiting factor for phytoplankton production. This "iron hypothesis" needs to be tested in various oceanic environments to understand the role of iron in marine biological and biogeochemical processes. In this paper, three in vitro iron enrichment experiments were performed in Prydz Bay and at the Polar Front north of the Ross Sea, to study the role of iron on phytoplankton production. At the Polar Front of Ross...     

上海市住房价格梯度及其影响因素分析

选择从上海市中心区至宝山区的一条南北向区段,通过采集沿线内环以内、内环和中环之间、中环和外环之间以及外环以外四个区间内二手房、新房的价格样本,分析其价格梯度差,发现二手房价格一般要高于新房价格,但其价格递减速度比新房更快。根据实际情况,提取繁华程度、市场供求比例、地理区位、交通条件、人口状况、基础设施、环境质量七个影响住房价格的主要因子,运用多元回归分析方法对样本区域的房地产价格进行分析,得出了多元线性回归方程,并进行了回归分析效果检验;最后分别运用偏相关系数分析法和单项因子权重度量法来估算各因子的影响程度。结果表明,二手房市场和新房市场具有明显差异,市场供求是影响二手房价格的最主要因子,而环境质量则是影响新开楼盘价格的首要因子;繁华程度和交通条件的重要影响作用在本次回归模型中没有得到验证。     

中国农村宅基地转型的理论与证实

土地利用转型是土地利用变化的表现形式之一,也是由IGBP和IHDP联合发起的全球土地研究计划 (GLP) 的重要研究内容。目前土地利用/覆被变化 (LUCC) 研究仍然有待进一步理论化,在学科综合与集成基础上提出的假设对土地变化科学显得尤为重要。土地利用转型研究需要寻求一种综合的方法,来对社会和环境变化的时间尺度和历史背景进行整合。通过分析特定时期内中国农村建房的影响因素及相应的管理政策,在了解中国农村建房发展过程的基础上,提出了中国农村宅基地转型趋势的理论假设：随着社会经济的发展,农村宅基地在增加的建设用地总量中所占比例将由高逐渐降低,直到这一比例趋向于一个固定值。最后运用长江沿线样带农村宅基地转型研究结果验证了该理论假设。

研究居民对居住小区环境归属感,进行定量评价并揭示其规律,可为指导城市小区规划设计提供依据。本文以调查问卷的形式,对大连市的居住小区进行调查,充分考虑评价因子的代表性和多层次性的特点,选取5项一级指标和25个单项指标建立评价指标体系;采用层次分析法与地理信息系统软件Surfer 8.0相结合的方法,对大连市居住小区归属感进行初步评价。研究结果表明:影响居住小区归属感的主要因子有舒适感、识别感、安全感、交流感、成就感;大连市居住小区归属感的整体评价较好,市内四区存在差异;归属感的高值区域分布在生态环境风景区、商务活动中心、靠近海岸线的地方及交通便利的地方。     

Climate Warming and Energy Consumed for Winter Heating in Xi'an

 The accumulated negative temperature, the first heating date, the last heating date, heating duration, collective heating area and energy consumption for winter heating in Xi'an during 1986-2002 were comprehensively analyzed. The results show that under the global warming, winter in Xi'an became warmer and heating duration shorter. With the development of economy, the area and energy consumption for collective heating increased continually. In the meantime, the energy consumption per unit area for winter heating decreased year by year, but it did not match the winter temperature well because the energy was not proportionally consumed according to the change of temperature. In order to conserve energy effectively, heating in winter should be timely adjusted according to actual temperature change.     

Study on consumption efficiency of soil water resources in the Yellow River Basin based on regional ET structure

Based on the regional water resources character, the concept of soil water resources is first redefined, and then associated with their transfer relationship in the hydrological cycle, Evapotranspiration (ET)-based consumption structure and consumption efficiency of soil water resources are analyzed. According to ET 's function in productivity, the consumption efficiency of soil water resources is di- vided into three classes: high efficient consumption from vegetation transpiration, low efficient con- sumption from soil evaporation among plants with high vegetation coverage and inefficient consump- tion from soil evaporation among plants with low vegetation coverage and bare soil evaporation. The high efficient and low efficient consumption were further classified as productive consumption. The ineffi- cient consumption is considered non-productive consumption because it is significant in the whole hydrological cycle process. Finally, according to these categories, and employing a WEP-L dis- tributed hydrological model, this paper analyzes the consumption efficiency of soil water resources in the Yel- low River Basin. The results show that there are 2078.89×108 m3 soil water resources in the whole basin. From the viewpoint of consumption structure, the soil water resources are comprised of 381.89×108 m3 transpiration consumption from vegetation and 1697.09×108 m3 evaporation consumption from soil among plants and bare soil. From the viewpoint of consumption efficiency, soil water re- sources are composed of 920.11×108 m3 efficient consumption and 1158.86×108 m3 of inefficient con- sumption. High efficient consumption accounts for 41.5 percent of the total efficient consumption of the whole basin, low efficient for 58.5 percent. Furthermore, consumption efficiency varies by region. Compared with ET from different land use conditions, the whole basin appears to follow the trend of having the greatest proportion of consumption as inefficient consumption, followed by low efficient consumption, and then the least proportion as high efficient consumption. The amount of inefficient consumption in some regions with vegetation is less than in other regions without vegetation. The amount of inefficient consumption in grasslands is much greater than in forestlands. However, the proportion of low efficient consumption is the greatest in crop fields. The amount of high efficient con- sumption in grasslands and forelands is similar to the corresponding low efficient consumption. However, the low efficient consumption in grasslands is larger than in the forelands. Therefore, when adjusting the utilization efficiency of soil water resources, vegetation coverage and plant structure should be modulated in terms of the principle of decreasing inefficient consumption, improving low efficiency ET and increasing high efficiency ET according to area character.
