Emerging economies provide interesting scenarios for examining how institutional context influences the financing behavior of firms. In this study, we examine the capital structure of Chinese listed firms following the SplitShare Structure Reform of 2005. This reform allowed a reduction of government ownership by making government shares tradable. We find that the impact of government ownership on leverage is dependent on whether the government is the largest shareholder in a firm and whether the government ownership is through a parent state-owned enterprise. In addition, we document that the largest non-government shareholder positively influences ***, our results reveal that the largest controlling shareholder, either government or non-government, has a significant impact on the capital structure of Chinese firms.

In this research, the denoising of speckled SAR image has been done with fuzzy filters (ATMED, TMED, ATMAV & TMAV). SAR image or Synthetic Aperture Radar image consists of the informatics of ISW (Internal solitary waves). A new technique has been proposed which preserved the edge pixels by fuzzy edge detection method and then altered with the filtered image-pixels by fuzzy filtration for getting the denoised image. The comparative result shows that the proposed filter performs better than the other filtered results in terms of PSNR (41.61 dB), MAE (1.47), MSE (4.54) for TMAVxAPE & SSIM (81%) for ATMEDwAPE. The proposed method in this research shows better SSI (Spackle Suppression Index) value. Therefore the experimental result illustrates that the suggested fuzzy filter is much more capable of simultaneously protecting edges and suppressing speckle noise. This research will be beneficial to remove spackle noise from SAR images and can be used for remote sensing and mapping of surface area of earth.

Background: Chronic kidney disease (CKD) is increasingly prevalent worldwide. CKD may present with different cutaneous manifestations. Objectives: To evaluate the dermatological manifestations and compare these manifestations between patients with maintenance hemodialysis (MHD) and non-dialysis groups. Methods: It was a cross sectional study conducted in the Department of Nephrology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from April 2013 to March 2014. A total of 150 hospital admitted CKD patients were evaluated for dermatological manifestations. Age, gender, haemoglobin level, 24-hours urinary total protein (UTP), serum creatinine, serum fasting lipid profile, estimated glomerular filtration rate (e-GFR) and dermatological manifestations of the study subjects were recorded accordingly. Inter-group comparisons were made between patients with and those without cutaneous abnormality. Results: Out of 150 study subjects, 99 (66%) were male and 51 (34%) were female, 69 (46%) patients were on MHD and 81 (54%) patients were without dialysis, their mean (±SD) age was 44.6 ± 12.3 year. A Total of 126 (84%) patients had cutaneous abnormalities;among them 69 (54.76%) were pre-dialytic and 57 (45.24%) were on MHD group. The mean (±SD) serum creatinine was relatively higher but haemoglobin level was significantly lower (p = 0.021), while UTP was significantly higher (p = 0.038) among patients with cutaneous abnormality. There was no relationship between lipid profile with cutaneous abnormality. Among 126 (84%) patients with cutaneous abnormality;pallor was the most common cutaneous abnormality (72%) followed by xerosis (68.66%), pruritus (65.33%), half and half nails (38.66%), pigmentation (33.33%), purpura/ecchymosis (16.66%), fungal infection (16%), ulcerative stomatitis (10.66%) and bacterial infection (10%). Pigmentation (52.6%), purpura (35.1%), ulcerative stomatitis (21.1%) and bacterial infection (19.3%) were significantly higher in MHD gro
