The result of the MFDFA shows that there exists obvious multifractal scaling behavior in produced time series. We compare the MFDFA results for original time series with those for shuffled series, and find that its multifractal nature is due to two factors: broadness of probability density function of the series and different correlations in small- and large-scale fluctuations. This may provide new insight to the problem of the origin of multifractality in financial time series.展开更多

The new system consists in combining double-entry general accounting with budgetary accounting, which is traditional in the public sector. The accounting reform of 2003 marks a turning point in the history of accounting of the federal State and federated entities (regions and communities). The Brussels-capital region is the first federated entity to embark on the adventure and implement the new accounting system in 2006. The aim of this article is to introduce the legislative framework and the different implementation steps of the accounting reform in the Brussels-capital region and to provide a financial analysis of the region. The objective is to see if the region has a good financial situation. To do this, this paper analyses the data from the balance sheet and the income statements from 2008 to 2011. On one hand, it analyzes the evolution of the region's different results; and on the other hand, it presents different financial ratios. It also analyzes the evolution of the regional debt. This paper concludes that, although expenses and the debt are increasing, the situation of the region is not worrying, because of good budgetary performances, sophisticated financial management, and law loans rates. Even if the results of the analysis don't have to be interpreted as the same way as for a private company, the annual accounts provide interesting information that can be used to improve public finance.展开更多

This abrupt change increases the interest on distributed generation (DG) because of its several benefits such as lower electricity generation price. In Iran among all type of DGs, because of wide natural gas network infrastructure and several incentives that government legislated to support combined cooling, heat and power (CCHP) investors, this type of technology is more prevalent in comparison with other technologies. Between existing CCHP technologies, certain economic choices are to be taken into account. For different buildings with different load curves, suitable size and operation of CCHP should be calculated to make the project more feasible. If CCHP does not well suited for a position, then the whole energy efficiency would be plunged significantly. In this paper, a model to find the optimal size and operation of CCHP and auxiliary boiler for any users is proposed by considering an integrated view of electricity and natural gas network using GAMS software. Then this method is applying for a hospital in Tehran as a real case study. Finally, by applying COMFAR III software, useful financial parameters and sensitivity analysis are calculated.展开更多

One area of topology has showed its immense potential in explaining potential financial contagion and financial crisis in financial markets. The aforementioned method is knot theory. The movement of stock price has been marked and braids and knots have been noted. By analysing the knots and braids using Jones polynomial, it is tried to find if there exists an untrivial knot equal to unknot? After thorough analysis, possible financial contagion and financial crisis prediction are analysed by using instruments of knot theory pertaining in that sense to Jones, Laurent and Alexander polynomial. It is proved that it is possible to predict financial disruptions by observing possible knots in the graphs and finding appropriate polynomials. In order to analyse knot formation, the following approach is used: “Knot formation in three-dimensional space is considered and the equations about knot forming and its disentangling are considered”. After having defined the equations in three-dimensional space, the definition of Brownian bridge concerning formation of knots in three-dimensional space is defined. Using analogy method, the notion of Brownian bridge is translated into 2-dimensional space and the foundations for the application of knot theory in 2-dimensional space have been set up. At the same time, the aforementioned approach is innovative and it could be used in accordance with stochastic analysis and quantum finance.展开更多

Three original indicators of PRIVY (private investment/aggregate investment), DEPTH (aggregate loan/GDP) and FDIVG (FDI/GDP) are used to construct the FD economic indicator through Principal Component Analysis approach. Then we use Granger method to analyze the relationship between the FD and the economic growth of Suzhou. Empirical test results show that the FD of Suzhou is the Granger reason of economic growth, while economic growth is not the reason for FD, because the relationship between the FD and the economic growth of Suzhou is just in the ″supply-leading″ period. In terms of Suzhou experiences, the local government should strengthen the protection of private investment, improve the institutional environment, and establish the reasonable financial structure. So we can concluded that FD could play a great role in promoting economic growth at the economy takeoff stage.展开更多

Using a content analysis approach of the annual reports form 10-K for the years 2006, 2007, 2008, and 2009, we find that the ERM disclosure is significantly and positively associated with the crisis, bank size, board independence, duality and significantly and negatively associated with profitability, leverage, and board size. This paper seeks to fill a gap in the literature by investigating the effect of the crisis on ERM disclosure in the US banking sector context, and gives an insight into the factors affecting risk disclosure practices during the financial crisis.展开更多

Moreover the stumpage value of each plot was calculated, and a comparison analysis of the results is presented. The work was carried out in Central Italy, in an aged Quercus cerris L. coppice in hill zones, with a 45% average slope. Short wood system harvesting was applied. Felling and processing were performed by chainsaw, while extraction with three different methods: plot No. 1 with mules, plot No. 2 with a tractor with winch, plot No. 3 with polyethylene chute line. Transport of firewood from the forest track to the landing was made by a tractor loaded as a mule. In the plot No. 1 the costs per unit mass (30.76 ∈·t33% ^-1) were higher despite having the lower cost per hour (39.99∈·th^- 1). The reason was the lower productivity (1.3 t33%·h^-1). The plot No. 2 had the highest cost per hour (66.79 ∈·h^-1). However, productivity was the highest (2.7 t33%·h^- 1). This aspect was notable from the financial point of view (24.74 ∈·t33%^-1). Plot No. 3 was the less expensive (23.92 ∈·t33%^-1). Comparing the three methods, a reduction of the costs through more appropriate extraction systems may increase the stumpage value from 8.3 to 9.65 ∈·t33%^- 1.展开更多

In the plot No. 1 the costs per unit mass (30.76 ∈·t33% ^-1) were higher despite having the lower cost per hour (39.99∈·th^- 1). The reason was the lower productivity (1.3 t33%·h^-1). The plot No. 2 had the highest cost per hour (66.79 ∈·h^-1). However, productivity was the highest (2.7 t33%·h^- 1). This aspect was notable from the financial point of view (24.74 ∈·t33%^-1). Plot No. 3 was the less expensive (23.92 ∈·t33%^-1). Comparing the three methods, a reduction of the costs through more appropriate extraction systems may increase the stumpage value from 8.3 to 9.65 ∈·t33%^- 1.
