Abstract Significantly more women than men are registered voters in the United States, and a higher proportion of women voters actually cast ballots on election day. Yet the 106th Congress (1999-2001) includes only 56 women members, 12% of the total membership of the House and Senate. Likewise, women hold only 22% of the total seats in state legislatures. The purpose of this article is to examine this paradox. It first examines the history of the women's movement in the United States. It then turns to an evaluation of women's progress in gaining elected office. Finally it considers three primary obstacles to women gaining equitable representation: solidarity among women, political culture, and the single-member district system now employed in the United States. 相似文献

Geography,Race, and Quantification 总被引：1，自引：0，他引：1
Perry L. Carter 《The Professional geographer》2013,65(4):465-480
This article reviews how race, quantification, and raced quantification have been used and written about in geography. Its two primary arguments are that race should be more central in the discipline and that a reluctance to address ontological and epistemological issues has left quantitative geography methodologically impoverished. These two issues merge in an examination of two cases where race is employed as a variable in quantitative models. The critique of these cases is not meant as a condemnation of quantitative geography but as an instructive example on which to construct a critical quantitative geography. The article ends by stressing the importance of quantification in geography and by presenting exemplars of race-critical quantification. 相似文献

The artesian springs of Tule Valley are similar to those of adjacent Snake Valley and Fish Springs Flat based on conductivity and temperature. All three valleys support Ranidae amphibians and the leechErpobdella punctata. The artesian springs in Snake Valley and Fish Springs Flat contain six and two species of fish and contained up to 18 and 12 species of mollusk respectively, whereas Tule Valley artesian springs contain neither fish nor mollusks. The leechesHelobdella stagnalis, Glossiphonia complanata, andHaemopis grandis were found in Snake Valley whereasHelobdella triserialis, Theromyzon rude, andHaemopis marmorata were found in Tule Valley. These springs which were covered by Lake Bonneville to a depth of several hundred meters, 16 000 BP., became isolated after the paleolake desiccated 13 000 years BP. The marsh snailCatinella is found above the paleolake level in Snake and Tule Valley and has not penetrated to the valley floor habitats once covered by the paleolake, whereas another marsh snailOxyloma has penetrated into these habitats in Snake Valley. The leech and molluscan distributions in Tule, Snake and Fish Springs Valleys suggest that the paleolake did not allow for much movement among the valleys, and successful passive aerial transport has not occurred after the paleolake desiccation 13 000 years BP. Paleozoological models are proposed to explain the presence and absence of these species in Tule Valley. Both lateral movement (along paleolake shorelines) and vertical movement (to new habitats formed after the desiccation of the paleolake) by amphibians, mollusks and leeches is restricted in large terminal lakes and is species dependent in both spatial and temporal scales of the hydrological cycle. 相似文献

AbstractThis study aims to theoretically investigate the notion of critical thinking for a more just understanding of self and “others” in global geographical learning. It focuses on the kinds of injustice in the world which are driven by our relationships with “others.” By drawing on the literature of critical education, philosophy of education, and geography education, this study reveals how universal notions of criticality tend to easily undermine those perceived as global others and may highlight, in deficit mode, their perceived differences. Instead, the study presents the imperative of deconstructive thinking for a more just world. The article concludes by proposing a teaching strategy for alternative criticality which strives for justice in school geography. 相似文献

This paper gathers potent visual images of one city, Los Angeles (L.A.), by examining three contemporary films— L.A. Story (1991), Boyz N the Hood (1991), and Grand Canyon (1991). It argues that popular culture, and in particular popular film, is an integral part of the portrayal of the cultural landscape. This paper primarily uses the assorted visual images of the urban landscape in considering how this one city has been recently depicted. The three films reveal a city shaped by rapid changes in urban America, depicting Los Angeles as an urban area composed of a fragmented landscape divided into many geographies: L.A. as a realm of simulations and void of consequences; L.A. as a city under siege, a place of epidemic violence and fear; L.A. as a place obsessed with security and control; L.A. as an increasingly ambiguous and chaotic place. Far from concluding that cities have become so fragmented that they are ageographic, these films reveal various geographies that are rooted in economic, political, and cultural contexts. Attention to the “restlessness” of cities and the postmodern focus on the instability and chaotic nature of urban experience actually challenge geographers to uncover the multitude of geographies of place. Interpreting the many geographies of Los Angeles shows that film can reveal a uniquely visual catalog of human experience of place, supplementing the ways in which we decipher place image and representation. This paper suggests that film is one way by which previously marginalized groups, such as blacks, can disseminate ideas from the margins and provide alternative experiencesof place. Geographers should add film to the cache of qualitative data that constructs an urban experience through images and representation, widening the discussion of what is place 相似文献

A substantial literature in social sciences, including law and society, examines the intersections of research ethics and institutional review board (IRB) frameworks. Although geographers have engaged this literature, we argue that further involvement in ethical and regulatory discussions will advance opportunities for better understanding and negotiating the complex subjectivities produced in the IRB structure. Drawing on illustrative experiences of researchers, we focus specifically on the institutions convening IRBs, the researchers, and the human “subjects” produced in the IRB process. We conclude with a call for greater open discussion of the power dynamics, subjectivities, and challenges of formal ethical research structures. 相似文献

This study examines the experiences of geography graduates who work in business, government, and nonprofit organizations. We analyzed 352 logs from eighty-two professionals detailing professional activities, challenges, and opportunities during one work week each month, over a period of six months. Our analysis explores interpersonal relationships and working conditions affecting participants’ progress toward work goals, workplace climate, and professional identity. Geographic information systems and technology accounted for more than half of the geographic skills respondents reported using on the job, and administrative and leadership factors were the most commonly cited types of transferable skills. Professional geographers value collaborative workplaces as well as opportunities to work independently with the confidence of their supervisors, and their sense of a professional identity is enhanced when they feel valued and are recognized for their work. Professional development activities are important because they reinforce geographers’ sense of positively contributing to their organizations, enhance interpersonal interactions, facilitate work on specific projects, and expand individuals’ knowledge and skills. Moreover, our findings suggest that nearly half of the reported workplace difficulties could potentially be reduced or eliminated as a result of more and better professional development. Nonetheless, many employers do not consistently provide opportunities for professional development to their employees. Based on our analysis, we contend that professional development is a beneficial investment for lifelong learning, from undergraduate and graduate education throughout the entire course of a professional career. 相似文献

The boehaviour and ultimate effect and fate of oil in the marine environment in the polar region depend on a large number of factors. From a chemical point of view the most important ones to consider are the intrinsic chemical properties of the oil, the consequences of oil/water interactions, the influence of ice on physical and chemical processes, and the interactions between oil and light when the influx of solar energy shows great seasonal changes. This paper reviews the main aspects of these issues. 相似文献

Northwestern California is prone to regional, high magnitude winter rainstorms, which repeatedly produce catastrophic floods in the basins of the northern Coast Ranges. Major floods on the Eel River in 1955 and 1964 resulted in substantial geomorphic changes to the channel, adjacent terraces, and tributaries. This study evaluated the changes and the effects of a moderate flood in 1997 through field observations and examination of aerial photographs that spanned from 1954 to 1996. The purpose was to document the nature and magnitude of geomorphic responses to these three floods and assess the rates and controls on the recovery of the Eel River and its tributaries. Channel widening from extensive bank erosion was the dominant geomorphic change along the lower Eel River during major floods. As a result of the 1964 flood, the largest amount of widening was 195 m and represented an 80% change in channel width. Channel narrowing characterized the periods after the 1955 and 1964 floods. More than 30 years after the 1964 flood, however, the river had not returned to pre-flood width, which suggests that channel recovery required decades to complete. A long recovery time is unusual given that the Eel River is located in an area with a “superhumid” climate and has an exceptionally high sediment yield. This long recovery time may reflect highly seasonal precipitation and runoff, which are concentrated in 3–5 months each winter. In contrast to the main stem of the Eel River, the dominant effects of floods on the tributaries of the Eel River were rapid aggradation of channel bed and valley floor followed by immediate downcutting. Dendrogeomorphic data, aerial photographs, and field observations indicate that thick wedges of gravel, derived largely from hillslope failures in upper reaches of the tributaries, are deposited at and immediately upstream of the mouths of tributaries as the stage of the Eel River exceeded that of the tributaries during major floods. In the waning stages of the flood, the tributaries cut through the gravel at a rate equal to the lowering of the Eel and generated unpaired terraces and nickpoints. The complete process of deposition and incision can occur within a few days of peak discharge. Although reworking of some sediment on the valley floor may continue for years after large floods, channel morphology in the tributaries appears to be a product of infrequent, high magnitude events. The morphology of the tributary channel also appears to be greatly influenced by the frequency and magnitude of mass wasting in headwater areas of small basins. 相似文献

中国人口迁移,流动人口与城市化——现实,理论与对策 总被引：1，自引：2，他引：1
中国改革前的城乡不平等关系已演变成城市中拥有本地户口的居民与没有本地户口的流动人口的不平等关系。目前的城市化可以说是不完全和排斥性的城市化。要达到完全的城市化,必须关注三个重要方面,包括常规的城乡迁移、城市对流动人口的融合与包容以及城市边缘区的城乡一体化。流动人口地位低下的情况,政府和企业对此负有部分责任。讨论在户口制度背景下城市化的基本理论和城市流动人口融合的理论,认为应使用系统方法去研究城市化和城乡一体化的课题,该方法可应用于不同尺度的人与自然共生系统的规划、发展、建设和扩展,同时以香港的马鞍山新市镇作为例子来展示如何规划和发展一个可持续社区,以满足现代城市居民的期望。 相似文献

According to many environmentalists, the U.S. transportation sector is being subsidized by federal, state, and local governments.
Whether or not road users are, in fact, paying the cost of using roads is a critical issue in supporting sustainable transportation.
Subsidies increase road consumption above levels that would otherwise be dictated by the market. This paper compares different
estimates of transportation subsidies, noting their strengths and weaknesses. Following this discussion, the issue of transportation
as a public good is covered. How economic efficiency and equity are considered depends in large part on the role of transportation
in society. If transportation is deemed a public good, then alternative evaluation criteria must be applied. If not, then
economic efficiency would need to be considered. Both efficiency and equity could be enhanced by a pollution tax. Such a measure
would improve equity by charging users for the pollution they generate. In addition, economic efficiency could be enhanced
by internalizing the environmental externalities associated with transportation. This study, compares different estimates
of transportation subsidies as a prelude to discussing economic efficiency and equity issues. The study does not develop a
definitive answer to the problem of transportation subsidies, but rather highlights the important public policy issues that
exist within this arena. 相似文献

In this study, we use a combination of geographic information systems and Bourdieuan social theory to analyze the development of a food policy council in Birmingham, Alabama. The questions we investigate are: What is the relationship between race and culture? How is this relationship manifest in practice within the alternative food and agriculture movement? In our work, we show how the racially segregated conditions of metropolitan Birmingham forge divergent habitus among Blacks and Whites in the region. Consequently, Whites have difficulty producing practices and interpretations of those practices that Blacks can recognize as legitimate, and vice versa. As a result, the food policy council emerges from and remains trapped within a space of Whiteness, and few Blacks serve on the council or participate in its production. 相似文献

Chemical weathering and associated soil development trends on glacial forelands are commonly assumed to exhibit increases with time elapsed since glaciation. However, this gross trend is complicated by several other factors including elevation, aspect, and microtopography. This paper demonstrates that on the glacial foreland at Storbreen, Jotunheimen, Norway, chemical weathering and associated soil development trends show significant elevational influences. We sampled soils at shallow depths (0–1, 1–5, and 15–20 cm) at two sites on a moraine dated to 1750 at its elevational extremes of 1155 m (site L) and 1385 m (site H). The two moraine sites also differed developmentally from an adjacent 9000-year-old surface (site T) at an intermediate elevation, 1205 m. Analyses were conducted on the fine-earth fractions. Extractable elemental composition exhibited detectable differences between the same-age soils at different elevations with the lower site L tending to have measured parameters intermediate between the high site H and the older site T. Weathering, as indicated by mineralogy, was more pronounced at the 9000-year-old site T and least evident at the high elevation site H. In addition, elevation under the conditions of the field research may inhibit pedogenesis as indicated by the chemical data. Site H, for example, showed little variation with depth and had in general, less organic matter accumulation, smaller C:N ratio, greater pH, and lesser amounts of the measured extractable elements than the soil at site L. Site T generally had smaller pH and larger levels of the measured elements than the other sites. It was concluded that elevation has a significant control on weathering and pedogenesis that may mask the effects of age in this cold and wet environment. 相似文献

This study investigates whether women's short commutes should be interpreted as constrained or convenient work trips by examining how race, gender, travel mode, occupation, residential location, workplace location, and Inc.ome affect commuting time. The analysis is restricted to a sample of European American and African American male and female workers residing in Buffalo, New York, and the surrounding county using data drawn from the Public Use Microdata Samples of the 1990 U.S. census. Given the pervasive gender wage gap, women unsurprisingly have more compromised (short commutes to low-Inc.ome jobs) work trips than do men. Multivariate analysis reveals that among those who reverse commute to suburban locations, African American women have the longest work trips. 相似文献

Forest city,Malaysia, and Chinese expansionism 总被引：2，自引：2，他引：0
Sarah Moser 《Urban geography》2018,39(6):935-943
Over the past decade, an acceleration of Chinese state and private investment in urban infrastructure and real estate has transformed many skylines around the world. In 2014, a private Chinese company in collaboration with Malaysia’s Sultan of Johor state started construction on Forest City, a private gated luxury mega-development for 700,000 people on four reclaimed islands in the narrow strait that separates Malaysia and Singapore. While the official material for Forest City claims it is for all nationalities, it is being marketed predominantly in China and to ethnic Chinese communities in Southeast Asia. This paper investigates the broader implications for Singapore, Malaysia, and the region and makes two key arguments. First, I suggest Forest City is more than a Chinese-financed real estate development, rather it constitutes a Chinese neocolonial outpost to which Malaysia has largely conceded sovereignty and advances China’s expansionist agenda. Second, Forest City challenges current geopolitical dynamics and threatens to undermine Malaysia’s relationships with neighbouring countries. 相似文献

The paper compares hydrographic and terrain categories in the geospatial data standards of the United States, Taiwan, and Russian Federation where the dominant languages used are from different language families. It aims to identify structural and semantic differences between similar categories across three geospatial data standards. By formalizing the data standard structures and identifying the properties that differentiate sibling categories in each geospatial data standard using well-known formal relations and quality universals, we develop a common basis on which hydrographic and terrain categories in the three data standards can be compared. The result suggests that all the three data standards structure categories with a mixture of relations even though most of them are well-known relations in top-level ontologies. Similar categories can be found across all the three standards. Cases of categories from different standards carrying identical meaning are rare. Partial overlaps in the meaning of the similar categories can be a direct result of different quality universals at work in defining and distinguishing these categories, or in the case of these categories being ordered by size, the threshold values for distinguishing the categories are ambiguous and language-dependent. Understanding these differences avoids incorrect mappings of categories in multilingual applications. More importantly, it provides a starting point for more effective mapping between hydrographic and terrain categories between English, Mandarin, and Russian. 相似文献
