油井含砂在线监测技术研究

井口含砂在线监测是国外近年来发展起来的一种高精度实时监测油井出砂研究手段。在引进SandQTM 含砂监测系统基础上对其配套技术进行了优化,首先,利用FEPG 系统开发了三维声波传导有限元程序,对井口声波测试弯管壁厚进行了优化,建议壁厚为510 mm;其次,建立了近井渗流稳定时间分析有限元模型,优化井口测试程序,结果表明,对于高渗疏松砂岩油藏,生产制度调整后24 h 以内近井渗流即可达到稳定,结合现场实际,将油井工作制度调整频率设计为1 次/d;最后,进行了现场试验,研究表明,该技术对于抽油机及电潜泵井采油树均具有较好适应性,对于产出液黏度较小的油井适应性强、测试精度高,对于产出液黏度较大（动力黏度>1 824 mPa
s）油井,适应性较差。     

Desh bidesh revisited

This article discusses the emergence of a ‘British Bangladeshi social field’. It makes two connected arguments about its effects. First, it argues that the emergence of the British Bangladeshi social field has rendered the discourses of desh and bidesh less important. Second, it argues that British Bangladeshis are embedded into many transnational social fields and lead multiply orientated rather than binary lives. It uses the example of the importance of the global Islamic umma (community) to British Bangladeshis to illustrate this and argues that it has also contributed to the decreasing importance of the discourse of the desh. What this shows is that the transnationalism of today is very different from that of 20 years ago, both in terms of how it is experienced and how it is analysed.     

磨溪气田嘉二段沉积相再认识

针对川中地区下三叠统嘉陵江组二段沉积环境的判别一直存在潮坪相和非潮坪相的争论,以磨溪气田岩芯精细描述、薄片鉴定、测井曲线分析为基础,通过对嘉二段沉积古地理背景、岩石类型、沉积构造、沉积韵律、古气候及成岩演化等方面的详细分析,发现磨溪嘉二段并非大面积分布的潮坪相,而是陆表海型碳酸盐岩局限台地相－蒸发海台地相,并以潮下还原环境为主,类潮坪沉积特征仅见于嘉二2B层,可识别出台坪、粒屑滩、滩间海、半局限-局限泻湖、蒸发泻湖等亚相及其多种不同的沉积微相。嘉二1亚段主要为半局限-局限-蒸发泻湖夹风暴岩沉积,嘉二2A层以发育鲕粒滩微相为特征,嘉二2B层以台坪亚相为特色,嘉二2C层发育砂屑滩和蒸发泻湖亚相。不同微相储集性能分析表明云坪、砂屑滩和鲕粒滩微相为最有利的储集相带     

Monumentally Indian: The Photography of Edward Curtis and the Cuzco School of Photography

Abstract

‘Monumentally Indian’ analyzes the similarities and differences in the representation of indigeneity in photography in the US and the Southern Peruvian Andes during the first decades of the twentieth century. The article shows an underlying (and often unconscious) poetic at work in the critical and popular reception of these photographic archives that undermines their potential for creating a radically new visual field.     

从布迪厄社会学理论视角看苏曼殊《惨世界》的翻译动机和策略

以法国社会学家皮埃尔·布迪厄的社会学理论为指导,主要从其核心概念“场域”、“惯习”入手,分析清末民初翻译家苏曼殊汉译《悲惨世界》的动机和策略,指出当时的社会历史条件和其个人的个性及价值观促使了译作《惨世界》的诞生,并影响了该译作的风格特点。     

Putting Bourdieu to work for class analysis: reflections on some recent contributions

Recent developments in class analysis, particularly associated with so‐called ‘cultural class analysis’; have seen the works of Pierre Bourdieu take centre stage. Apart from the general influence of ‘habitus’ and ‘cultural capital’, some scholars have tried to reconstruct class analysis with concepts drawn from Bourdieu. This involves a theoretical reorientation, away from the conventional concerns of class analysis with property and market relations, towards an emphasis on the multiple forms of capital. Despite the significant potential of these developments, such a reorientation dismisses or neglects the relations of power and domination founded in the economic institutions of capitalism as a crucial element of what class is. Through a critique of some recent attempts by British authors to develop a ‘Bourdieusian’ class theory, the paper reasserts the centrality of the relations of power and domination that used to be the domain of class analysis. The paper suggests some elements central to a reworked class analysis that benefits from the power of Bourdieu's ideas while retaining a perspective on the fundamentals of class relations in capitalism.     

Responding to student mental health concerns in social work education: reflective questions for social work educators

In this paper, we explore ways in which social work educators might respond to students who report that mental health issues underlie their difficulty in meeting core competencies, or otherwise use the language of mental health to describe their struggles to succeed in social work programs. We discuss various trends in policy responses in Canada, the US, the UK, and Ireland. While there are general policy trends, it is clear that responding to these kinds of issues requires the development of highly flexible and situated policy processes that can respond to student realities, concern for students’ rights and privacy, and an awareness of potential discrimination against students. These processes also need to meet the specificities of practicums, particular institutional policies, the mandates of relevant professional bodies, and the precise local legislative framework that shapes these situations. Given these varying contexts, in this conceptual paper, we used a framework on disability that is informed by critical theory to engage existing school policies and propose a set of reflective questions that can guide schools of social work to create an overall responsive environment. These reflective questions are designed to help social work educators balance the rights and needs of students with the professional and institutional demands that students meet core competencies in their education.     

生态翻译视域下的景介翻译

中英旅游景介文本在语言形式、语篇和内容等方面存在着诸多差异,因此景介文本的翻译充分考虑文本与受众经验的“游离”与“契合”的关系。生态翻译学强调翻译生态环境中所有构成素间的关联和整体性,译者需在语言维、文化维及交际维的适应性选择转换,才能保证作者、译者和读者互惠互利、健康有序的生态循环。     

(Un)Available upon Request: Field Experiment on Researchers' Willingness to Share Supplementary Materials

This article reports results of a field experiment in which two hundred e-mails were sent to authors of recent articles in economics that had promised to send the interested reader supplementary material, such as alternative econometric specifications, “upon request.” The e-mails were sent either by a researcher affiliated at Columbia University, New York or the University of Warsaw, Poland; furthermore, the authors' position (assistant professor) was specified in half the e-mails only. Overall, 64% of the approached authors responded to our message, of which two thirds (44% of the entire sample) delivered the requested materials. The frequency and speed of responding and delivering were very weakly affected by the position and affiliation of the sender. Gender or affiliation of the author, number of citations or journal impact factor or the type of object in question seemed to make no difference. However, authors of published articles were much more likely to share than authors of working papers.     

网络场域：人口学研究的空间转向

空间是人口学研究的核心概念,是人口学理论的一个基本分析视角,是人口学方法的一个重要分析工具。随着网络社会的崛起,人类生存与发展的空间发生了变化,人口学发展产生了新的理论框架和新的问题意识。转向网络场域是人口学对空间研究的反思。是人口学随着网络社会崛起对空间研究的理论自觉。基于拥有独立研究对象、有理论基础的支撑和研究方法的支持,网络人口学得以可能。
