Taking the temperature – forecasting GDP growth for mainland China
No full textWe present a new composite leading indicator of economic activity in mainland China, es-timated using a dynamic factor model. Our leading indicator is constructed from three se-ries: exports, a real estate climate index, and the Shanghai Stock Exchange index. These series are found to share a common, unobservable element from which our indicator can be identified. This indicator is then incorporated into out-of-sample one-step-ahead forecasts of Chinese GDP growth. Recursive out-of-sample accuracy tests indicate that the small-scale factor model approach leads to a successful representation of the sample data and provides an appropriate tool for forecasting Chinese business conditions.forecasting; China; leading indicator; factor model; growth cycles

Widening the gap – Indigenous affairs
No full textThe author points out the implications for aboriginal Australians of the decision to cut funding for Aboriginal and Torres Strait Islander Services. Curran gives individual examples to show how early intervention to give aboriginals effective access to services and avoid jail helps to close the gap between aboriginal and non-aboriginal people and saves taxpayers’ money
Letter from M.J. Curran to Hagan
No full textHolograph letter from M.[J.Curran], Rome, to Hagan. Sr. Rita progresses well; she does suffer from typhoid after all. Explaining the matter concerning the Enright Burse; a draft has been received. In Tivoli, a new municipal tax is imposed on all building materials; asking for advice. Latest progress on the Via Santi Quattro site. The Civiltà Cattolica has apparently excelled itself in an attack on the author of the Isola Smeralda; promising to send the issue
British regional growth and sectoral trends: global and local spatial econometric approaches
No full textInternational audienceThis paper looks beneath the surface of British sub-regional aggregate GVA growth over the period 1995-2007, by examining how the differing growth dynamics of the secondary and services sectors have influenced the overall regional growth process. A spatial econometric analysis is undertaken which tests regional secondary and services real GVA per capita for absolute and conditional convergence at the NUTS 3 level. Both local and global spatial analysis techniques are utilised in order to gain a detailed insight into the growth process over the period 1995-2007. A number of explanatory factors influencing secondary and services sector regional economic growth are also identified

Shelters need 500,00 increase in funding instead of a hoped-for 100,000 was found, increasing the state funding by $6 per person per night.

Numerical prediction of vortex dynamics in inviscid sheet cavitation
No full textRecent studies have indicated that mass transfer models are able to correctly reflect the sheet cavitation dynamics of inertia driven flows, given that the mass transfer model constants governing the source term magnitude are sufficiently large (Koukouvinis and Gavaises 2015) and that enough temporal resolution is provided (Schenke and Van Terwisga 2017). The inertia driven dynamics, characterised by cavity collapse time, shedding frequencies and local pressure impact frequencies, were shown to be insensitive to variations of the mass transfer coefficients in this limit.This study focuses on an inviscid cavitating flow around a NACA0015 hydrofoil. The flow dynamics are driven by the re-entrant jet as the main mechanism of cavity shedding. A threshold of mass transfer magnitude, temporal and spanwise spatial resolution is identified, beyond which the frequency of local pressure impacts is model parameter independent. Although the excact values of peak pressure loads remain time step size, grid size and model parameter dependent, the sheet cavitation dynamics are considered as well resolved in this regime as far as shedding frequency and characteristic cavity collapse time are concerned. The results are compared to experimental results by Van Rijsbergen et al. (2012).Based on this, the study further focuses on the mechanism of vorticity generation and vorticity break-up, causing potentially erosive cavitating structures such as horseshoe cavities (Dular and Petkovˇsek 2015).Accepted Author ManuscriptShip Hydromechanics and Structure
