Economic sustainability of heritage conservation in Hong Kong: The impact of heritage buildings on adjacent property prices

Informed by the theoretical framework of sustainable development and economic theories including the cluster theory and the corollary of the Coase Theorem, this paper empirically investigates the economic impact of architectural heritage in Hong Kong. Using the hedonic price model, the research examines the economic impact of 50 publicly owned versus 50 privately owned heritage buildings on adjacent residential property prices with a sample size of over 43,240 property transaction records spanning a time period of 10 years. The research supports that heritage conservation can promote economic sustainability aside from cultural sustainability and social engagement. This research benefits government policymakers, urban planners, architects, and heritage conservationists by contributing new knowledge to the studies on sustainable urban development, heritage conservation, and cultural economics

The Transverse Particle Migration of Highly Filled Polymer Fluid Flow in a Pipe

Shear-induced particle migration was investigated by using a continuum diffusive -flux model for the creep flow of nickel powder filled polymers, which are viscous with shear-thinning characteristic. The model, together with flow equations, was employed for solving the non-Newtonian flow patterns and non-uniform particle concentration distribution of mono-modal suspensions in a pressure-driven tube flow. Particle volume fraction and velocity fields for the non-homogenous shear flow field were predicted for 40% particle volume fraction. The model captures the trends found in experimental investigations.Singapore-MIT Alliance (SMA

Breast feeding in Australia: A comparative study of Aboriginal and non Aboriginal women

The superiority of breast feeding over bottle feeding is universally acknowledged, and its crucial contribution to infant health is accepted by health authorities. Australia in recognition of the importance of breast feeding to infant health, aims to increase the prevalence of breast feeding. Breast feeding provides benefits for all children, however the health advantage that is gained by breast feeding in comparison to artificial feeding is more apparent among disadvantaged groups. Aboriginal Australians are identified as one such disadvantaged group. This study compares the available literature regarding the prevalence of breast feeding in Aboriginal and non Aboriginal women. It is apparent that breast feeding prevalence differs, between population groups within Australia. Aboriginal children are less likely to have been breast fed than non Aboriginal children. The comparison, indicates that there are deficiencies in the research regarding breast feeding prevalence in both population groups. Many factors affect a woman's decision to breast feed, and the duration of her breast feeding. These factors include, socioeconomic status, age, marital status, educational attainment, occupation and smoking status. These factors are clearly associated with breast feeding in non Aboriginal women. For Aboriginal women, the factors influencing breast feeding are more complex. It is recommended therefore, that it is essential for future research to examine the attitudinal and socialdeterminants of infant feeding practices in Aboriginal women. This is necessary, if educational or interventional strategies are to be effective for this population

Large-eddy simulation of low-frequency unsteadiness in a turbulent shock-induced separation bubble

The need for better understanding of the low-frequency unsteadiness observed in shock wave/turbulent boundary layer interactions has been driving research in this area for several decades. We present here a large-eddy simulation investigation of the interaction between an impinging oblique shock and a Mach 2.3 turbulent boundary layer. Contrary to past large-eddy simulation investigations on shock/turbulent boundary layer interactions, we have used an inflow technique which does not introduce any energetically significant low frequencies into the domain, hence avoiding possible interference with the shock/boundary layer interaction system. The large-eddy simulation has been run for much longer times than previous computational studies making a Fourier analysis of the low frequency possible. The broadband and energetic low-frequency component found in the interaction is in excellent agreement with the experimental findings. Furthermore, a linear stability analysis of the mean flow was performed and a stationary unstable global mode was found. The long-run large-eddy simulation data were analyzed and a phase change in the wall pressure fluctuations was related to the global-mode structure, leading to a possible driving mechanism for the observed low-frequency motions

Information (and library) science at City University London; 50 years of educational development

The development of education for information and library science at City University London over a 50-year period is described in this article. The development of the Masters course in Information Science, and the later equivalent courses in Library Science and in Information Management in the Cultural Sector are described in detail, together with shorter-lived Masters courses in pharmaceutical and health information. The rationale for changes to the courses, and the influence of the professional and educational contexts, are analysed. Issues emerging from this analysis are discussed in seven themes: the nature of the discipline; the library/information spectrum; the student group; the academic/professional balance; curriculum design; local and global issues; and teaching methods. The discussions of the courses are set in the wider context of changes in library/information education over the period in the UK and worldwide

Data from: Intergenomic interactions between mitochondrial and Y-linked genes shape male mating patterns and fertility in Drosophila melanogaster

Under maternal inheritance, mitochondrial genomes are prone to accumulate mutations that exhibit male-biased effects. Such mutations should, however, place selection on the nuclear genome for modifier adaptations that mitigate mitochondrial-incurred male harm. One gene region that might harbor such modifiers is the Y-chromosome, given the abundance of Y-linked variation for male fertility, and because Y-linked modifiers would not exert antagonistic effects in females because they would be found only in males. Recent studies in Drosophila revealed a set of nuclear genes whose expression is sensitive to allelic variation among mtDNA- and Y-haplotypes, suggesting these genes might be entwined in evolutionary conflict between mtDNA and Y. Here, we test whether genetic variation across mtDNA and Y haplotypes, sourced from three disjunct populations, interacts to affect male mating patterns and fertility across 10 days of early life in D. melanogaster. We also investigate whether coevolved mito-Y combinations outperform their evolutionarily novel counterparts, as predicted if the interacting Y-linked variance is comprised of modifier adaptations. Although we found no evidence that coevolved mito-Y combinations outperformed their novel counterparts, interactions between mtDNA and Y-chromosomes affected male mating patterns. These interactions were dependent on male age; thus male reproductive success was shaped by G×G×E interactions
