Spatial distribution of suicide in Queensland, Australia
Background: There has been a lack of investigation into the spatial distribution and clustering of suicide in Australia, where the population density is lower than many countries and varies dramatically among urban, rural and remote areas. This study aims to examine the spatial distribution of suicide at a Local Governmental Area (LGA) level and identify the LGAs with a high relative risk of suicide in Queensland, Australia, using geographical information system (GIS) techniques.---------- Methods: Data on suicide and demographic variables in each LGA between 1999 and 2003 were acquired from the Australian Bureau of Statistics. An age standardised mortality (ASM) rate for suicide was calculated at the LGA level. GIS techniques were used to examine the geographical difference of suicide across different areas.---------- Results: Far north and north-eastern Queensland (i.e., Cook and Mornington Shires) had the highest suicide incidence in both genders, while the south-western areas (i.e., Barcoo and Bauhinia Shires) had the lowest incidence in both genders. In different age groups (â€24 years, 25 to 44 years, 45 to 64 years, and â„65 years), ASM rates of suicide varied with gender at the LGA level. Mornington and six other LGAs with low socioeconomic status in the upper Southeast had significant spatial clusters of high suicide risk.---------- Conclusions: There was a notable difference in ASM rates of suicide at the LGA level in Queensland. Some LGAs had significant spatial clusters of high suicide risk. The determinants of the geographical difference of suicide should be addressed in future research

The Relation between Initial Returns and Audits by the Big Four Accounting Firms
This paper mainly explores the relation between initial returns and audits by the big four accounting firms (the Big Four) in China. The sample period is from January 2007 to December 2012 (the new accounting standards in China is implemented after January 2007 for integrating with the international standards), and selected 1,069 IPO firms listed in the Shanghai Stock Exchange and Shenzhen Stock Exchange in this paper.Many previous studies have proposed the Informational Hypothesis, which states that the initial returns of IPOs being audited by the Big Four are lower than those IPOs being audited by other accounting firms. Oppositely, this paper proposes the Snap-up Hypothesis due to consider the IPOs in mainland China are characterized by âthree lows,â: the low reliability of audits being performed by non-Big Four, low proportion of IPOs audits being performed by the Big Four, and low balling ratio. These âthree lowsâ features indicate that the Snap-up Hypothesis applies in the IPOs market of mainland China. In other words, the initial returns of the IPOs being audited by the Big Four are higher than those IPOs being audited by other accounting firms due to the Big Four have the superior reputations.This paper further collects the trading volumes and the turnover ratio on the first day, and selects the Big Four audited IPOs by snap-up tide. As above mentioned, because the snap-up tide and raised stock prices on the first-day listing, investors may purchase the shares when offering and sell them on the first-day listing to obtain considerable profits
Research On Waste Heat Recovery Of Low Temperature Flue Gas In Cement Plant And New Type Heat Exchange
Based on the measured data of low-temperature waste gas at the outlet of waste heat boiler of a new dry cement production line in a cement factory in China, this paper investigates the utilization of waste heat, and formulates the technical scheme of waste heat utilization, and focuses on the design of the key waste heat exchanger for waste heat utilization, and carries out technical and economic analysis. According to our calculation results, the low-temperature waste heat recovery of cement plant has great potential. Using this technology can save more energy and obtain good economic benefits.In addition, a new type of heat pipe heat exchanger is designed and briefly introduced in this paper, aiming at the current situation that the existing heat exchange equipment only has heat exchange function without considering dust removal function.The design inspiration of the new type of heat pipe heat exchanger comes from cyclone and heat pipe heat exchanger, which combines the advantages of high heat exchange efficiency of heat pipe heat exchanger and good dust removal effect of cyclone.Heat exchange equipment for low temperature waste heat recovery needs to have some unique performance requirements.It can provide better choice for waste heat utilization of cement plant
AdS/BCFT and Island for curvature-squared gravity
In this paper, we investigate AdS/BCFT for curvature-squared gravity. To warm
up, we start with Gauss-Bonnet gravity. We derive the one point function of
stress tensor and show that the central charge related to the norm of
displacement operator is positive for the couplings obeying causality
constraints. Furthermore, by imposing the null energy condition on the
end-of-the-world brane, we prove the holographic g-theorem for Gauss-Bonnet
gravity. This corrects a wrong point of view in the literature, which claims
that the holographic g-theorem is violated for Gauss-Bonnet gravity. As a
by-product, we obtain the boundary entropy and A-type boundary central charges
in general dimensions. We also study AdS/BCFT for general curvature-squared
gravity. We find that it is too restrictive for the shape of the brane and the
dual BCFT is trivial if one imposes Neumann boundary conditions for all of the
gravitational modes. Instead, we propose to impose Dirichlet boundary condition
for the massive graviton, while imposing Neumann boundary condition for the
massless graviton. In this way, we obtain non-trivial shape dependence of
stress tensor and well-defined central charges. In particular, the holographic
g-theorem is satisfied by general curvature-squared gravity. Finally, we
discuss the island and show that the Page curve can be recovered for
Gauss-Bonnet gravity. Interestingly, there are zeroth-order phase transitions
for the Page curve within one range of couplings obeying causality constraints.
Generalizing the discussions to holographic entanglement entropy and
holographic complexity in AdS/CFT, we get new constraints for the Gauss-Bonnet
coupling, which is stronger than the causality constraint.Comment: 49 pages, 29 figures, revision accepted for publication in JHEP, main
improvements: prove that our g-function can recover the universal term of
boundary entropy in general dimensions; add a toy model to explain the novel
zeroth-order phase transition of the Page curve analyticall
