Using data on individuals from the 2008 American Community Survey, we examine the relationship between educational attainment and the location of jobs in fifteen large metropolitan areas in the United States. We focus on whether individuals with higher educational attainment tend to work in the central city versus the suburbs, and we do so taking into account the residential location of households (central city vs suburb). We show that central cities tend to be the work site of more highly educated workers—those with a bachelor’s degree and above. Workers with less than a high school degree also tend to work in the city. Taking account of the residential location preferences of highly educated workers mildly diminishes the direct effect of higher education on city job location, but it does not negate it. In contrast, central city job opportunities for workers with less than a high school education are not so abundant; these workers tend to work in the city mostly because they also live there. 相似文献

AbstractAn increased focus on housing diversity in planning policy, international flows of capital and changing lifestyle preferences are resulting in increased higher density housing often marketed towards professional singles, couples without children and ‘empty nesters.’ Despite this, families with children currently dwell in higher density housing, either by choice or by necessity. This research identifies the social representations surrounding children in higher density housing in Australia’s third largest city, Brisbane. It does this by analysing newspaper media published between 2007 and 2014 and through 46 interviews with residents and built-form professionals from Brisbane. The research finds four key representations; that children belong in the suburbs; increasing support for wealthy families in higher density housing; an economic argument for the lack of family-appropriate apartments; and an increasing acceptance of medium-density housing for younger households. This research draws attention to the winners and losers in housing debates and the ‘common-sense’ assumptions that impact housing outcomes. 相似文献

This paper examines the extent to which Chicago's Gautreaux residential mobility program affected children's residential attainment. Low-income black families voluntarily relocated into mostly white or mostly black city and suburban neighborhoods. The paper integrates quantitative and qualitative data collected eight to 22 years after participants' initial move into their placement neighborhoods. The primary programmatic goal of desegregation was accomplished; now-adult children's origin, placement and current neighborhoods average 85.6, 29.9 and 44.5 per cent black residents respectively. Now-adult children's residential mobility decisions have located them, on average, in ethnically integrated, low-poverty neighborhoods; children placed in mostly black, high-poverty neighborhoods and those placed in mostly white, low-poverty neighborhoods have relocated to ethnically balanced low- to moderate-poverty neighborhoods. Suburban placement was key in determining the level of children's initial relocation and current neighborhood quality. Now-adult children currently residing in suburban cities live in higher quality neighborhoods compared to those currently residing in Chicago. 相似文献

Landscape and the philosophy of aesthetics: is landscape quality inherent in the landscape or in the eye of the beholder? 总被引:4,自引:0,他引:4

The paper proposes that landscape quality assessment may be approached on the basis of two contrasting paradigms, one which regards quality as inherent in the physical landscape, and the other which regards quality as a product of the mind – eye of the beholder. These are termed, respectively, the objectivist and subjectivist paradigms. These paradigms underlie the surveys of the physical landscape and studies of observer preferences.Examination of these paradigms through the approaches taken by philosophers from Plato to modern times demonstrates the ubiquity of the paradigms in underlying human perception of landscape. Until recent centuries, the objectivist paradigm provided philosophers with the basis for understanding beauty, including landscape beauty. However, the philosophers Locke, Hume, Burke and particularly Immanuel Kant identified beauty as lying in the eyes of the beholder rather than in the object. The parallels between Kant's aesthetic philosophy and contemporary theories of landscape quality based on an evolutionary perspective are examined. Most philosophers over recent centuries have adopted the subjectivist view of aesthetics.The paper concludes by proposing that only the subjectivist model should be used in research of landscape quality. 相似文献

The effects of design and operational factors on the dynamics of ciliated protozoa in constructed wetlands (CWs) treating wastewater remain poorly known, although bacterivory by ciliates could have important implications for nutrient cycling in these systems. We conducted a greenhouse experiment with eight wetland mesocosms (1 m2) fed with synthetic wastewater to assess how macrophyte species (Phragmites australis, Phalaris arundinacea, and Typha angustifolia), location within CW (longitudinal, depth), and temporal fluctuations affect ciliate abundance and diversity. Urosoma similis was the most abundant taxon, but Hypotrichidae, Scuticociliates, Drepomonas revoluta, and Acineria uncinata were also abundant. Longitudinal location had the highest impact on ciliate dynamics, with more abundant and diverse communities in the initial section of wetlands. P. australis/T. angustifolia and P. arundinacea had the most and least favorable conditions for ciliates, respectively, but differences among macrophytes were mostly not significant. Ciliate abundance appeared to decline from August to November, most likely because of lower temperature and plant inputs of organic matter and oxygen. Depth had no apparent impact on ciliate dynamics, suggesting that sampling at multiple depths in CW is not necessary to adequately monitor ciliate communities. Overall, our results suggest that macrophytes, location, and date of sampling influenced ciliated dynamics but stress the need for direct manipulative experiments of ciliate abundance, diversity, and composition conducted on a full annual cycle to better understand the impact of ciliates on nutrient cycling in CWs. This is especially true to determine if the associations found in our principal component analysis are robust. 相似文献

Previous studies at the Svartberget catchment in northern Sweden have identified potential terrestrial sources of methylmercury (MeHg) and total mercury (THg) in runoff as well as processes controlling MeHg/Hg transfers from soil to runoff water. This paper considers whether the concepts based on a few seasons of observations are consistent with catchment budgets of MeHg/THg over half a decade. Inter-annual and seasonal variations in the input and output fluxes of THg/MeHg, in open field wet deposition (OF), litterfall (LF) and runoff water are evaluated together with more recently measured concentrations that include the throughfall water (TF) data. The input and output flux data of THg and MeHg from the Svartberget catchment are also compared to those from the G?rdsj?n Catchment. The average annual MeHg input fluxes in OF, TF and LF are 0.08, 0.17 and 0.3 g km(-2) year(-1), respectively. The comparable inputs for THg are 7, 15 and 17 g km(-2) year(-1). Thus, LF is as important as TF for THg inputs, while LF is twice as important as TF for MeHg inputs. The annual output flux of MeHg varied between 0.05 and 0.14 g km(-2) year(-1). The annual output flux of THg varied between 1 and 3.4 g km(-2) year(-1). The large inter-annual variations in catchment output did not follow the smaller variations in atmospheric input. This suggests that changes in climate can effect terrestrial outputs of THg/MeHg to surface water more than atmospheric deposition. These data do not contradict the earlier findings that it is the hydrological and biogeochemical processes in the riparian zone that have a central role in determining the amount of MeHg reaching surface waters from forested catchments. The juxtaposition of major flow paths and organic-rich soils in the riparian zone may create the locations of most importance for net MeHg production, runoff export and a larger pool of MeHg. 相似文献

Research into the locational decisions of creative class or knowledge workers has indicated that “classic” or “hard” factors, particularly employment opportunity and social connections, generally take precedence over “soft”, “quality of place” amenities such as art and cultural venues, historical assets, and tolerance/diversity. However, “soft” amenities are expected to shape where creative class/knowledge workers live within cities, and potentially whether they remain in the community long-term, or seek opportunities elsewhere. In this study, an online survey and questionnaire were employed to explore whether residents living in downtown Omaha, Nebraska with “creative” occupations exhibit stronger preferences for urban amenities relative to those with “non-creative” occupations. Generally in support of Richard Florida’s creative class thesis, the results suggest that creative workers may exhibit a stronger affinity for certain, primarily “soft,” urban amenities and characteristics, such as dining establishments, “third places”, arts/cultural venues, unique sense of place, and the hip, trendy, and youthful feel of Omaha’s downtown neighborhoods. 相似文献
