青藏高原土壤水热分布特征及冻融过程在季节转换中的作用

利用GAME-Tibet期间所取得的高分辩率土壤温度和含水量资料，对青藏高原（主要是藏北高原）土壤水热分布特征及冻融过程在季节转换中的作用进行了分析。指出藏北高原4cm学深处土壤在10月份开始冻结，次年4-5月份开始消融，冻结持续时间长达5-7个月。冻结过程有利于土壤维持其水分，因此，在刚刚开始消融时土壤含水量仍然很高。从而为夏季风爆发前土壤通过蒸发向大气提供水分打下了基础。指出土壤冻融过程可能在高原季节转换中起着重要作用。     

Marxism, Sarcasm, Ethnography: Geographical Fieldnotes from South India

This paper addresses questions of ethnography in geographic fieldwork through research conducted on globalisation and work in Tiruppur, an industrial boomtown in South India. During the last two decades of the twentieth century, Tiruppur town in western Tamilnad State became India's centrepiece in the export of garments made of knitted cloth. This industrial boom has been organised through networks of small firms integrated through intricate subcontracting arrangements controlled by local capital of Gounders from modest agrarian and working‐class origins. In effect, the whole town works like a decentralised factory for the global economy, but with local capital of peasant‐worker origins at the helm. My research explores the historical geographic trajectories linking agrarian and industrial work, and the ways in which these histories are used in the present. In these uses of the past in remaking self and place, I interrogate the self‐presentations of Tiruppur's entrepreneurs, as these “self‐made men” hinge their retrospective narratives of class mobility and industrial success on their propensity to “toil”. This paper explores questions of ethnographic method emerging from a political‐economic context in which globalisation has worked by turning “toil” into capital.     

(Hetero)sexing Space: Gay Men and “Straight” Space in Adelaide,South Australia

This paper examines gay men's perceptions and experiences of everyday places in Adelaide, South Australia. It illustrates the nature of social space as a heterosexual artifact. The paper also outlines ways in which gay men may contribute to the heterosexualization of space. Many gay men monitor the public and private roles they play for fear of the consequences of “discovery,” and through self-policing and restricted behaviors they may contribute to the spatial supremacy of heterosexuality. Acts of nondisclosure and the adoption of straight sexual facades constrain gay men's social and spatial lives.     

Placing man in the New West: Masculinities of The Last Picture Show

The Last Picture Show does not fall within the genre of the Western, yet the cinematic narrative mourns the loss of the iconic Westerner — a man — and the passing of his home places that constitute the Old West. This paper is concerned with the ways in which this man and his places are transformed along with the embryonic but inexorable emergence of the New West — and its attendant demand for recognition of hitherto unheard voices (e.g., women, Latinos) — that accompanied significant social, cultural and political shifts that were beginning to emerge within the country as a whole in the represented early 1950s. His represented sites of contestation are found within the frame of the small west Texas town of Anarene, created by Larry McMurtry's novel of the same name as the film, both of which reflect contexts of the era in which they were constructed — the mid 1960s to early 1970s. We suggest that the film shows a great sensitivity to the ways in which particular masculinities are constituted in specific places, to the tensions that arise from the changing nature and definitions of masculinity as they are linked to these places, and with his sense of nostalgia and loss that accompanies his inevitable decline. But there is no clear and empowered place for women in these new places, only a recontextualized form of a patriarchal order which is not relational and which still maintains essentialist assumptions of gender. The Old West has taken new shape, much to the chagrin of man, but it is hardly a New West, with its emerging and representative voices.

RURAL DEVELOPMENT IN EL HATILLO, NICARAGUA: GENDER, NEOLIBERALISM AND ENVIRONMENTAL RISK

El Hatillo is a rural community in the Sébaco valley in Nicaragua, which suffers from an eroding resource base, high levels of poverty and malnutrition, and a high susceptibility to hazards. Structural adjustment policies have been devastating for small and subsistence farmers and have increased the level of economic, social and environmental marginalisation in rural Nicaragua. This paper explores initiatives to promote sustainable development in Nicaragua in the context of structural adjustment and environmental degradation. Drawing on qualitative research conducted in El Hatillo, it outlines the ways in which women in this community are attempting to address the multiple challenges of rural poverty and environmental risk and considers the potential of these strategies for gender equality.     

Gender and agrobiodiversity: a case study from Bangladesh

Local geography and gender are two major factors determining which crop varieties are cultivated in a case study of two rural villages in Bangladesh. This paper explores the interrelationships between gender, agrobiodiversity, and the use of, and preferences for, improved and local crop varieties. These are examined in relation to rice, minor field crops, and home garden fruits and vegetables. Reasons for both the displacement and the persistence of local varieties (LVs) are analysed in comparison to improved variety (IV) diffusion. The research evaluates agrobiodiversity through the number, types, and varieties of crops grown in fields and home gardens. The desired agroecological, economic, and cultural characteristics of crops grown document how respondents rank their variety preferences. Variety preferences and the perceived importance of LV preservation are compared with what is actually grown. The study indicates that there was little variation between villages in their approach towards the use of IV and LV rice; IVs were cultivated for their high yields and LV rice for taste and culinary uses. However, there were significant differences in relative agricultural dependence between the two villages which led to unique variety preferences. In both villages, women's preferences for IVs or LVs play a major role in crop choices, particularly as they manifest themselves in gendered domains of authority.     

"居住不稳定性"对中国大城市流动人口健康的影响研究

随着城镇化加速和人口“流动性”增强,中国大城市流动人口的健康问题备受关注。流动人口的居住具有典型不稳定特征,分析其对流动人口身心健康的影响具有重要意义。为此,本文采用北京、深圳、上海等9个大城市的实地调研数据,运用层级回归和分组回归,探讨影响流动人口身心健康的因素,关注“居住不稳定性”因素的影响。研究表明：城市内部多次迁居和城市间频繁流动对流动人口健康具有显著负面影响;住房因素中,自有住房和选择居住在本地人居多的邻里对其健康具有显著正面影响。另外,“性别”因素具有调节效应;居住不稳定性对主观幸福感和自评生理健康的影响程度因“性别”不同而有所差异,男性健康对时空因素更为敏感和脆弱,女性健康不佳多归因于住房和邻里。     

广州城市道路网的社会分异——基于轨迹大数据的出行分布性别差异

社会空间分异是人文地理学研究的重要议题,以往研究主要聚焦基于居住地和活动地的分异现象,缺乏对道路网社会空间分异的关注。本文以广州市中心区域为例,结合日常活动空间理论和空间分析方法,基于手机轨迹大数据,研究不同性别群体日常出行的城市道路网社会空间分异现象及其影响因素。结果显示：基于性别差异的城市道路网社会隔离指数高于居住地、低于就业地,在14:00—15:00时段达到峰值;不同性别群体在路网中的分布总体呈现不均衡的集聚特点,其中女性集聚程度更高;不同性别群体的出行分布和分异受到路网周边建成环境因素的影响;物流运输业就业密度的提高、小学数量的增多或道路等级的提高都会显著提高男性相对出行量,而社会服务业就业密度的提高、菜市场数量或公交站点数量的增多以及到市中心距离的减少都会显著提高女性相对出行量,这些与个体家庭和职业分工的性别差异有一定的关系。本文通过理论假设和实证分析,验证了家庭和职业的分工决策是影响道路网出行分布性别分异的深层次原因,也是解释社会空间分异的重要理论视角。研究结果有助于认识和挖掘基于城市道路网的社会分异现象及其影响机制,并为完善道路网络及周围设施的布局与建设提供借鉴。     

Where Are the Women? Accounting for Discrepancies in Female Doctorates in U.S. Geography

Although there have been noticeable improvements in recent years, geography continues to be a predominantly male discipline. The percentage of women receiving PhDs in geography has tracked lower than the U.S. average of female PhDs. Previous studies of women's contribution to geography have focused on personal accounts or on the study of some of the most prominent practitioners, with a few studies using basic data on PhDs awarded and Association of American Geographers membership to determine trends. This article provides a comprehensive overview of doctoral degrees in geography by gender, over time, and across all universities in the United States by examining an alternative database, that of doctoral dissertations. The analysis yields three separate types of results. First, historical and contemporary variations among U.S. universities are examined. Second, data indicate that male and female doctoral students differ in the sex of their advisor. Third, a simple regression model explains some of the discrepancies in the proportion of female doctoral students by department. In sum, this article provides a comprehensive empirical study of the factors that might contribute to the continued disparities in female doctoral students in geography.     

Lesbian and Queer Sustainable Farmer Networks in the Midwest

Heteropatriarchy underpins contemporary U.S. agriculture, even within the alternative sector. This paper builds on the legacies of women farmers and farmers of color creating peer networks to circumvent heteropatriarchal hurdles by investigating how lesbian, bisexual, trans, and queer (LBTQ) sustainable farmers access human resources. If and how did the farmers encounter or resist heteropatriarchy in this process? Drawing on four years of ethnographic research with 40 LBTQ Midwest sustainable farmers, I argue that resources through government agencies, neighborhood farmers, and like-minded practitioners did not necessarily align with LBTQ farmers’ sustainable practices or queer identities. LBTQ farmers convened with others at the intersections of their queerness and sustainable practices formally, informally, and through the labor market to access human resources removed from heteropatriarchal domination. I conclude that LBTQ farmer networks bolster human resources in sustainable agriculture and conservation practices.
