We believe that hukou status is only one of several factors responsible for migrants’ differential housing outcomes, and that the research literature has not spent enough time assessing the relative importance of these factors. While not definitive, our empirical results provide several reasons to question a hukou-centric model of the sources of urban housing inequality.

This paper fills some of the gaps regarding housing choice, demand, and quality among China’s rural-to-urban migrants using data from a purpose-designed survey of 800 low-status migrants in Tianjin. Results show that many migrants do not to exercise housing ‘choice’ but, rather, undergo housing ‘sorting’ that follows from occupational choices. Less than half of respondents obtained housing in the private rental market and only a slightly higher share pay any rent. Employment variables (industry sector, employer type) are consistently and strongly significant across our housing choice models and significantly affect housing quality as well. Nonetheless, a low-cost rental sector does exist, serving about two-fifths of migrants in our sample. Within this subset, housing demand is more consistent with theory in the sense that income and life cycle factors are important and employment sector has weaker effects. We read the study’s findings as an indication that the primary policy prescription of the urban China housing choice literature as it pertains to rural-to-urban migrants – the need to eliminate institutional barriers that limit access to certain kinds of housing - is desirable but inadequate and may not respond to the concerns of migrants themselves.

The invention relates to a method for producing butadiene from n-butane, comprising the steps of A) providing an input gas flow a containing n-butane; B) feeding said input gas flow a containing n-butane into at least one first dehydrogenation zone and dehydrogenating n-butane in a non-oxidative catalytic manner, whereby a product gas flow b containing n-butane, 1-butene, 2-butene, butadiene, hydrogen, low-boiling secondary components, and optional steam is obtained; C) feeding the product gas flow b resulting from the non-oxidative catalytic dehydrogenation process and an oxygen-containing gas into at least one second dehydrogenation zone and oxidatively dehydrogenating 1-butene and 2-butene, whereby a product gas flow c containing n-butane, 2-butene, butadiene, hydrogen, low-boiling secondary components, and steam is obtained, said second product gas flow c having a higher butadiene content than product gas flow b; D) eliminating hydrogen, the low-boiling secondary components, and steam, whereby a C4 product gas flow d essentially comprising n-butane, 2-butene, and butadiene is obtained; E) feeding the C4 product gas flow d into a distillation zone and separating a butadiene/butane mixture as a valuable product flow e1 such that a flow e2 substantially comprising n-butane and 2-butene remains; F) redirecting flow e2 into the first dehydrogenation zone.

"Submitted as final report for Nongame Wildlife Program project NG94-017, December 1995.", Includes bibliographical references (p. 82)., Introduction -- Methodology -- Results -- Funding for wildlife -- Wildlife-related activities of Floridians -- How Floridians receive their information on Wildlife -- Agency recognition and responsibility -- Values Floridians associate with Wildlife -- What Floridians think the Commission should do to help wildlife -- Nuisance wildlife problems -- Discussion and conclusions -- Literature cited -- Appendix A: Conventions used for cross-tabulations -- Appendix B: Tabular response distributions - 1995 Survey -- Appendix C: Respondent comments -- Appendix D: 1995 Survey instrument., This study was conducted to assess Floridians' current awareness and knowledge levels, opinions, and attitudes toward wildlife conservation in Florida. The major objective of the survey was to document and update public attitudes toward wildlife and identify trends which have occurred since 1985. Public opinion was assessed through a random-digit dialing telephone survey. Methodology included randomly-generated telephone numbers as well as randomization within households to ensure that the survey results can be projected to the adult, resident, Florida population. Results from the 1995 telephone survey were compared to data collected from telephone surveys using similar methodology and identical questions in 1985 and 1987., Electronic reproduction.
