岭南汉民系服饰文化景观比较与地理分异

根据服饰文化与环境相感应原理,即是在以湿热气候为主和地理区位、社会经济条件差异的背景下,岭南汉民系服饰各有其独特的文化风格.文中通过对其服饰文化景观横向比较,析出其差异,即分布在江河丘陵地区的广府人服饰文化景观具有多元化特征;深处山区的客家人服饰文化景观特征单一;居住在沿海的福佬人服饰景观特征是精细、耐水.根据以上这些景观差异,划分出广府、客家、福佬三大民系服饰文化亚区.     

Shifting production/shifting consumption: A political ecology of health perceptions in Kumaon,India

Despite rapid economic growth, India has not seen the improvements in food and nutritional security that other developing countries have had. This “Asian enigma” has generated a wealth of economistic analyses seeking to explain the persistence of poor nutrition, yet few studies have looked at everyday experiences of changing food systems, and how this impacts nutritional practices as well as the processes of subject formation. In this paper, I draw on qualitative research conducted in Uttarakhand, North India and examine how state-led shifts in agricultural production have resulted in changing food consumption practices and diminished perceptions of health. Villagers link this decreased health to increased chemicals in home-produced food, greater dependence on the market for food purchases, and generational changes in dietary preferences. Despite villagers’ cognizance of the negative health effects of these practices, they largely view these byproducts of capitalistic development with an air of inevitability. Following Mansfield (2011) this paper contributes to the political ecology of health literature by employing the concept of food as a “vector of intercorporeality” (Stassart and Whatmore, 2003:449) and bringing this into conversation with a poststructuralist understanding of subjectivity. I argue that within shifting landscapes of agriculture production and food consumption, notions of diminished health are indicative of the complex and always incomplete processes of subject formation. I view shifting health perceptions as intimate bodily resistances to agricultural development, and conclude that within agricultural development programs a focus on bodily health and well-being is a fecund platform for further experimental research that seeks to imagine development differently.     

城市扩张时空度量与差异性分析——以东、中、西部典型城市为例

城市化是区域人口增长与社会经济发展的综合进程,其最为明显的特征是城市空间扩张。研究采用面向对象最近邻分类以及概率神经网络分类的方法,从Landsat TM影像中提取我国东(广州)、中(合肥)、西部(西宁)城市主城区建设用地信息,应用皮尔逊卡方检验、香农熵模型以及城市扩张速度等计算3个城市相同时间段内的城市扩张自由度、蔓延度、感观优劣度等,对研究区1995—2010年期间的扩张特征进行时空综合度量。结果表明:1)不同城市扩张特征不尽相同,东(广州)、中部(合肥)城市相较西部(西宁)扩张自由度及蔓延度偏高,区域差异明显;2)东(广州)、中部(合肥)城市扩张感观优劣度相对较低,应努力构建并完善城市扩张监管体系,统筹协调城市建设用地的开发利用,积极推进高质量城镇化,实现城市的可持续发展;3)东(广州)、中部(合肥)相较西部(西宁)近15年扩张明显,扩张速度较快。     

喜马拉雅山南部的构造复杂性

根据对恒河盆地西部的多振型宽频带面波频散资料的分析推断,该区的地壳结构不具有大陆地盾的特征,相反,却非常象某些海洋高地。这一异常的海洋型地壳与恒河盆地东部地盾地壳的分界线可能在阿拉瓦利山脉（Aravalli Ridge）。该处地壳的地质特征具有异常高的电导率,其走向垂直于喜马拉雅山脉。目前广为接受的假定认为是构造均匀的印度大陆岩石圈向喜马拉雅山下俯冲。本文的研究结果对此观点提出了置疑:在北部印度大陆内的地壳运动可能存在着差异。我们追溯印度-欧亚大陆的碰撞历史,这个因素恐怕是不容忽视的。

Effect of geometric and material discontinuities on the reeling of pipelines

The winding and unwinding of a pipeline onto a large diameter reel as practiced in the reeling installation method, induces bending strains of 1–3% followed by straightening, and reverse bending. The operator must ensure that such plastic deformations are sustained free of local buckling or rupture in the line. Such failures are for example precipitated by pipeline discontinuities in wall thickness and yield stress as they act as stress risers, lead to localized deformations severe enough to result in local buckling. The effect of such discontinuities is studied using a large-scale nonlinear finite element model that simulates the reeling/unreeling of a pipeline. Nonlinear kinematic hardening is used to capture the elasto-plastic behavior of the material imposed by the bending/reverse bending history. Discontinuities in wall thickness and yield stress are shown to result in sharp local changes in curvature that extend over 3–4 pipe diameters accompanied by severe local straining and ovalization. The extent of the disturbance is governed by the bending strain imposed by the ratio of pipe to reel diameter. It can be reduced by an increase in the applied tension but at the expense of additional ovalization of the pipeline. It can also be reduced by increasing the pipe wall thickness but with the consequent increase in costs. A parametric study of the effect of such discontinuities demonstrates that for some combinations of process parameters, the disturbance can lead to local buckling either during winding or unwinding. It is concluded that a modeling framework such as the one presented should be used to generate a design protocol for reel-installed pipelines.     

国土整理测量的特点、内容及实施方法

为国土整理工作提供的测绘保障,称之为“国土整理测量”,它主要由“面”的规划调查测量和“点”、“线”的实施工程测量组成。权属调查、行政区划调查是国土整理测量工作的重要组成部分,在某些情况下,还须进行人口与水资源调查。国土整理测量必须建立土地台帐,并达到综合利用土地台帐的目的。日本等经济发达国家在20纪50年代即巳开展了长期化、制度化的国土整理工作,而我国则刚刚起步,因此尚存在没有统一的技术标准、总体规划性不强、缺乏前瞻性和国土整理测量成果没有得到综合利用等问题。所以：依据我国国情,借鉴国外经验,探讨国土整理测量的特点、作业流程及实施方法,为即将到来的大规模国土整理测量提供必要的理论依据与技术标准、实施方法与手段,具有很强的必要性与迫切性。

Small-scale variability of zooplankton pyruvate kinase activity in the Gironde Estuary plume (Atlantic French Coast): A case study under unusually low freshwater discharge

Pyruvate kinase (PK) activity measurements are used to assess the role of carbohydrates in global feeding of mesozooplankton communities inhabiting an estuary plume. As a consequence of a remarkably low freshwater discharge rate, the sea surface layers of the area under estuarine influence showed a very moderate salinity fall and a nearly total depletion in nitrates, whereas higher levels of these nutrients were found in deeper, more saline, layers. Small-scale PK activity variations in mesozooplankton appear to be closely correlated to nitrate integration values within the water column. The results were analysed in comparison with literature reports. The study produced a coherent overall interpretation, which strongly supports the reliability of this new biochemical tool in detecting assimilation of trace carbohydrates in the diet of mesozooplankton.
