multi-function characteristic. How to evaluate the multi-functional nature of housing is very useful in both theory and in application, yet it is often ignored in China. This paper introduces an approach to estimate the muhicriteria function of housing using multiattribute utility theory (MAUT) based on consumers' ordinal multicriteria peferences as determined via questionnaires. When compared with the classic framework in which MAUT is applied, this approach needs less prior information and subjective comparisons and thus can allay many of the operational difficulties involved in assessment. Some potential applications to the China housing market are also discussed. 相似文献

Problem, research strategy, and findings: Local governments across the United States have for decades relied on the autocentric level of service (LOS) metric to analyze and impose exactions for the transportation impacts of land use developments. In California, LOS has dominated transportation impact analysis under the state’s project-level environmental review law. In that role, LOS has exacerbated the state’s notoriously tortuous development approval processes, particularly in urban areas. But LOS is on its way out. The state recently replaced LOS with vehicle miles traveled (VMT) as the primary measure—and basis for mitigation—of transportation impacts under the California Environmental Quality Act. Local governments must make the switch by July 1, 2020. We use a historical counterfactual approach to assess how replacing LOS with VMT could have affected the approval process for 153 land development projects over 16?years in the city of Los Angeles. We find that most projects could have benefited from at least some environmental review streamlining under the VMT-based framework recommended by the state, including more than 75% of residential-containing projects.
Takeaway for practice: Our results suggest that swapping LOS for VMT could reduce the environmental review burden for development in low-VMT urban areas and provide at least some of the approval process streamlining necessary to increase housing production in California. Similar impacts from an LOS-to-VMT switch could also potentially accrue outside of California under the right conditions, but more research is needed. 相似文献

The public housing programme in Puerto Rico was highly influenced by a culturally engrained logic of colonialism that aimed to achieve a behavioural transformation of the residents of public housing based on white “criollo” norms and conducts. To this day, the process of Othering with which these bodies are understood and viewed has recurrently been reproduced and redeployed utilizing the island’s old racial/colonial hierarchies. Criminality and drug-related activities are the main discursive agents employed to stigmatize the communities that live inside public housing in Puerto Rico. It is constantly inferred that most of its residents break with the behavioural norms that the rest of the population abides by. This argument is constantly utilized to perpetuate the cultural lens that views these sectors as lazy, unruly and dangerous. This highly prejudiced misconception justified the police occupations and the fences that were erected in and around public housing premises during the 1990s. However, most of these communities rarely view themselves as victims, and it is this paper’s argument that they are constantly and collectively enacting political and physical spaces of dissent, resistance and encounter that – however momentarily – are able to overturn some of these powerful ideological and spatial constructs. 相似文献

AbstractWhen it comes to issues of housing policy, remote Indigenous housing often presents the extreme case. The failures of housing policy are most acute in remote Indigenous Australia, but despite the need to learn from the policy mistakes of the past, there has been little detailed analysis of the policy history. Through documentary and empirical analysis, we show that policies have either failed to be adapted to cultural and geographic contexts or, when they have been culturally responsive, they have lacked attention to the complexities of service delivery. Despite differences in policy settings, the long view is one of the normalization of Indigenous communities, although research points to the need for culturally appropriate arrangements. We argue that rather than politically motivated short-termism, governments need to develop a medium- to long-term approach that approaches policy solutions incrementally, builds capacity within the state and Indigenous communities, and is based on the evidence. 相似文献
