The current paper examines the relationship between health financing (public and out-of-pocket health financing), CO2 emission and health outcomes in 35 Sub-Saharan African countries for the period of 1995–2012. The panel unit root and cointegration tests are conducted as pre-tests, followed by the estimation of the parameters using the FM-OLS and DOLS techniques. The findings of the study show the importance of public health financing as one of the major factors that lead to better health outcomes, whereas the out-of-pocket expenditure is found to be harmful to population health since it leads to increase under-5 mortality rate. Although the results show a negative relationship between CO2 and health outcomes, still these results remain inclusive. In addition, the findings reveal the importance of socioeconomic factors such as income and education as key determinants of health outcomes. 相似文献

In this paper, a pan-sharpening method, using non-subsampled contourlet transform (NSCT) and the theory of compressive sensing (CS), is proposed. The NSCT is used for sparse image representation to perform a multiscale and directional decomposition of source images in order to express their detail and express the sparsity of their high frequency. The CS is used to merge the multispectral (MS) and panchromatic (pan) images from partial random measurements. Two different fusion rules are then applied. The final pan-sharpened image is obtained by inverse NSCT. Experimental results show the efficiency of the proposed method, compared with pan sharpening based on standard NSCT, in terms of visual quality and objective assessment. Moreover, the proposed technique is very effective when the storage and transmission bandwidth are limited. 相似文献

The morphological evolution of shallows seabed has undergone great changes over the past 95 years. These changes have not only led to the decreases of water volume but also to the spatial variability of sediments. However, the distribution and the movement of marine sediments from underwater beaches are very complex due to the combination of several factors such as hydrodynamic factors (e.g., tidal currents ±?34 cm, swells and currents driven by the prevailing northeast wind), and entropic factors (e.g., soil occupation and protective installation of structures as breakwater, groynes, retaining wall). This situation can disrupt the sedimentary regime in the Boumerdes area. In order to better understand the hydrodynamic processes, the recognition of sedimentary processes, the modalities, and erosion mechanisms of this zone are necessary. Thus, the study of long-term underwater morphological evolution by comparing between the bathymetric surveys of different years, between 1922 and 2017, is required to study the feasibility of coastal engineering projects. The seabed bathymetric evolution of this coastal fringe from erosion point of view was appreciated. It is based on a geographic information system (GIS), which allows to carry out a digital depth model interpolated by kriging method. 相似文献

The historical records show that the Northwestern Algeria has experienced more than 130 floods, which were sometimes catastrophic. They caused more than 1000 deaths and significant damage. In this work, we try to reconstruct the most devastating and deadly historical flood that occurred on November 26 and 27, 1927. This event is interesting to discuss disaster scenario because of its extent and impacts and the availability of data. For this purpose, we used historical press reports, scientific papers, and archival reports. This work allowed the reconstruction of the hydroclimatic situation during the flood and the regional scale impacts. It presents also the catastrophic flooding of the Ain Sefra river at Mostaganem and that of El Hammam river, as well as the Fergoug dam breaking at Mohammadia. The main factor triggering these floods was the heavy rainfall. Other factors have increased the damage such as the occupation of high-risk areas and the human failure. This event caused 430 killed persons, more than 1200 disaster victims, and around one billion francs losses. These effects evidence the high vulnerability of the Northwestern Algeria to the occurrence of floods. For that, if a similar event occurs in the future, it can be extremely negative. 相似文献
