A Long-Run Model of Housing Affordability

As a result of the recommendations of the Barker Review of Housing Supply in 2004, the Department of Communities and Local Government in England commissioned the construction of an econometric model of regional housing markets in order to examine the effects of different levels of housing construction on long-run affordability. The model has been regularly used as part of the policy-making process in England. The paper describes the structure of the model, which includes sectors covering house prices, household formation, tenure, migration flows, demographics and labour markets. Furthermore, through simulation analysis, the paper examines some of the key policy questions that have occurred in UK housing in recent years.     

30 kbar Phase Equilibria of the La2O3–SrO–CuO System at 950°C

Phase equilibria of the La₂O₃–SrO–CuO system have been determined at 950°C at 30 kbar (3 GPa). Stable phases at the apexes of the ternary phase diagram are CuO, La₂O₃, and SrO. Stable intermediate phases are La₂, CuO₄ and La₂Cu₂O₅ in the LaO_1.5–CuO binary and Sr₂CuO₃, SrCuO₂, and Sr₁₄Cu₂₄O₄₁ in the CuO–SrO binary. The La_{2– x} Sr _x -CuO_4–δ solid solution is stable for 0.00 is ≤ x ≤ 1.29, the La_{2– x} Sr_{1+ x} Cu₂O_6+δ solid solution is stable for 0.03 ≤ x ≤0.20, the La_{2– x} Sr _x Cu₂O_5–δ solid solution is stable for 0.00 ≤ x ≤1.08, and the La _x Sr_{14– x} Cu₂₄O₄₁ solid solution is stable for 0.00 ≤ x ≤ 6.15. The 30 kbar phase diagram differs from the 1 atm (0.1 MPa) and 10 kbar (1 GPa) results principally in the absence of La_{1– x} Sr_{2+ x} Cu₂O_5.5+δ as a stable phase and the extended range of the La_{2– x} Sr _x Cu₂O_5–δ solid solution at 30 kbar.     

Phase Equilibria of the Calcium Oxide-Copper Oxide System in Oxygen at 1 atm

Phase equilibria in the CaO-CuO system have been determined at 1 atm pressure in oxygen over the temperature range 800° to 1300^deg;C. CaO is the stable phase at the calcium-rich end of the system. Two intermediate crystalline phases, namely Ca₂CuO₃ and Ca₃Cu₇O₁₀, form. Ca_zCuO₃ is stable up to 1085°± 3^deg;C, where it melts incongruently to CaO + liquid (peritectic liquid has ε82% CuO). Ca₃Cu₇O₁₀ becomes stable at 977°± 3^deg;C by reaction between Ca₂CuO₃ and CuO. Ca₃Cu₇O₁₀ melts incongruently at 1046°± 3^deg;C to Ca₂CuO₃+ liquid (peritectic liquid has ε83% CuO). CuO is the stable copper oxide phase up to 1061°± 3^deg;C at the copper-rich end of the system; at higher temperatures, Cu₂O is stable until the liquidus is reached at 1121^deg;C. The binary eutectic is at 1045°± 5^deg;C, in which a liquid with 83% CuO coexists with Ca₃Cu₇O₁₀ and CuO.     

Investigating the integrated landscape of the intellectual topology of bioinformatics

We aim at identifying (1) whether and how various data sources influence mapping an intellectual structure of the field of bioinformatics, and (2) the landscape of bioinformatics by integrating those sources. To this end, we conduct a comprehensive bibliometric analysis by harvesting bibliographic information from DBLP, PubMed Central, and Web of Science. We then measure and compare topological characteristics of networks generated using these sources. The results show a dichotomous pattern dominated by PubMed Central and WoS. In addition, a few influential scientists in the field of bioinformatics receive very high citations from their colleagues, which is a driving force to bloom the field. These few scientists are connected to a much larger research community. Most of the researchers are intellectually linked within a few steps, in spite of the domain’s interdisciplinary characteristics. Particularly, influential authors consist of a small world. We also identify that there is not a coherent body of discipline in bioinformatics since the field is still under development. Finally, the journals and conferences indexed by each source cover different research topics, and PubMed Central is more inclusive than DBLP as an indexing database.
