PurposeThe purpose of this paper is to understand the demand pattern and housing preference of young consumers in Guangzhou, China. This study seeks to offer more information for urban planners and housing developers about housing demand from social and cultural perspective.Design/methodology/approachAssisted by a questionnaire survey, a housing environment preference pattern is generated by ranking quality attributes with respect to their relative importance to young consumers. The outcome is analysed by pair‐wise comparison of attributes based on the analytic hierarchy process (AHP).FindingsIt is found that “public traffic network” (11.72 per cent), “proximity to workplace” (10.22 per cent), “sense of safety” (9.74 per cent), “medical and health facility” (8.54 per cent) and “education facility” (8.50 per cent) are the top five determinants in housing consumption of young consumers in Guangzhou.Research limitation/implicationThe database used is relatively small.Originality/valueThe housing environment has been well‐researched in developed countries, but not in Guangzhou, China. This is one of the few papers that looks at the housing physical and social environment preference for young consumers using an AHP framework.

Good jetting performance and pigment‐dispersing stability are necessary for pigment‐based ink‐jet inks. This study investigates how the chemical structures of the polymeric dispersants affect the pigment‐dispersing stability and jetting performance of ink‐jet inks. A series of polymeric dispersants containing styrene (hydrophobic unit) and acrylic acid (hydrophilic unit) with different ratios have been synthesized and used to disperse different pigments. Because 3000–12,000 ink drops can be expelled from the nozzle of a thermal bubble‐type ink‐jet printer within 1 s, the jetting behavior is related to the rheology variation of a dilute solution under a high shear. An in situ drop formation system has been used to study the high‐shear‐rate rheology (dynamic surface tension and dynamic viscosity) of a solution with a viscosity lower than 3 cps, which no commercial rheometer can measure. Excellent ink‐jet inks can only be produced by the combination of pigments, dispersants, and surfactants with appropriate hydrophilicity. Moreover, the correlation of the pigment surface properties, the chemical structures of the polymeric dispersants, and ink formulation is discussed. The effects of the surfactants and firing conditions on the jetting behavior of the ink‐jet ink are also examined. © 2003 Wiley Periodicals, Inc. J Polym Sci Part B: Polym Phys 41: 1909–1920, 2003
