It also aims to predict future LULC map for the year 2030 using Markov Model to provide city planners and decision makers with information about the past and current spatial dynamics of LULC change and strictly urban expansion towards successful management and better planning in the future. Images from Landsat 5-TM for the years 1984, 1999 and from Landsat 8-OLI for the year 2014 were used to investigate LULC within the study area during 1984-2014 and the resulted LULC maps in 1999 and 2014 were used to predict future LULC map based on Markov Model. The results indicated that the urban/built up area expanded by 147% during the period from 1984 to 2014 and predicted to expand by 43.9% from 2014 to 2030 based on Markov model predictions. The areas in the western, northwest and southwest parts of Amman as well as the areas of Marka and Uhud, the northeast of the study area, were predicted to witness the major urban expansion in 2030. And these are the areas where city planners and decision makers should take into consideration in future plans of Amman. The urban expansion was mainly attributed to the high population growth rate and large number of immigrants from neighboring countries and other socio-economic changes.展开更多

In this study, groundwater vulnerability map for Amman Zarqa Basin (AZB) has been generated based on information derived and calculated from processed remote sensing information and laboratory analysis. The database was prepared from soil hydro geological and hydrological data, Digital Elevation Model (DEM), and geological maps. For assessment of groundwater vulnerability, the method proposed by the state geological surveys of Germany (GLA-method) has been adapted and applied. The vulnerability map shows about 77% which is about 2919 Km2 of the AZB is classified as very low to low which could be corresponding to the pollution sources due to the absence of potential hazards and also due to low vulnerabilities. These areas could consequently be interesting for future development as they set preferable in view of ground water protection. In addition, about 14% (530 km2) is classified within the moderate vulnerability zone. About 5% (around 19 km2) of the study area lies under the area of high vulnerability zone. Only 4% can be classified as very high risk areas. Groundwater quality results revealed that water leach ate from point source is the main cause for groundwater contaminations in highly vulnerable karstic limestone aquifer (Amman Wadi Es Sir Aquifer-B2/A7). On the other hand, the Kurnub Sandstone aquifer (K) is generally well protected in the central and eastern part of the AZB due to its thick cover of partly marly sequences. However, the Kurnub aquifer might have a potential risk from the recharged infiltrating surface water from the Zarqa River, which is highly polluted due to industrial activities located along the river.展开更多

The deterioration of natural resources and green areas, was coupled with the creation of different urban public open spaces in the city. The transformation from large single-family houses to dense residential apartments was associated with social and behavioral changes among the inhabitants living in the dense apartments. Consequently, a large private sector has been developed to provide public and social spaces. Photo-interpretation and satellite images were used to map and characterize land use/cover changes have been occurred in the Amman area between 1953 and 2017. Maximum Likelihood Classification method was employed to identify land use/cover changes between 1986 and 20017, and GIS was utilized also to map examples of the recently emerged socio-economic open spaces. Excessive urban development in the last two decades, and the adoption of neo-liberal privatization policies by the government, enhanced social stratification and residential segregation. So, instead of encouraging outdoor activity and social interaction among all groups of Amman residents, the freedom of accessibility to major open spaces has been restricted within the same urban fabric, thus, the “two Ammans” paradigm, a “tale of two cities”, has been recently acknowledged.展开更多

It was first established in 2012 to host Syrian refugees. Currently the camp hosts more than 81,000 refugees, with no proper sanitary system which might pose a major threat to surface resources in the area. An investigation was done at Za’atari refugees’ camp to find the impact of refugees settling on surface and groundwater quality. Surface water quality of surface runoff generated from thirty rain fall events were collected during the winter season of 2013/2014 from the major Wadi that passes through the camp and small ponds within the camp after the rainfall event. The collected samples were analyzed for acidity (pH), the electrical connectivity (EC), total dissolved solids (TDS), nutrients (NO3<sup style='margin-left:-7px;'>- and PO4<sup style='margin-left:-7px;'>3-) and selected heavy metals (Mn, Cd, Zn, Pb and Ni) in addition to biological oxygen demand (BOD5), chemical oxygen demand (COD) and intestinal worms (Total Coliform, E. cali). The results showed that there are significant variations in the EC as well as with TDS between the sites due to fluctuating amounts of water used for different activities within the camp as it was highest in the center of the camp where most of the refugees settle decreasing away from the center. The pH values were within the specifications of the World Health Organization and the Jordanian Standards. For nutrients, nitrate concentration was low with high phosphate ions which are most probably from detergents origin.展开更多

POE studies concerned with efficiency of building performance after using and implementing with the end-user. It provides feedback on the current status of the building and proposes solutions to existing problems in addition to guidelines and design criteria for the best solutions in the future. Despite precedent research which have been undertaken in the context of building performance, aspects of evaluating building performance have not been specified and used widely in Jordan. At the commencement of this research, the concept of POE is still new in Jordan, and the local building practitioners are still unfamiliar with this approach for the evaluation of a building performance in Amman. Accordingly, there is a need to undertake this kind of research in Jordan to identify the main guidelines of POE to be applied effectively in ceremonial and public buildings. This study therefore applies POE of indoor environment of the public buildings by exploring the guidelines that can constitute a successful and effective framework for the public buildings in Amman. This was achieved using the learnt lessons from Amman City Hall building which was used as a case study and reflecting them on these where needed. Analytical and descriptive approach basis was applied, adopting a mixed method approach （qualitative and quantitative method） by using observation tool and a questionnaire survey with occupants. Context-derived data and statistics analyzed together were used to explore the guidelines of POE to be applied effectively in public buildings. A field visit and observation tool was adopted for gathering information leading to the findings and recommendations. A questionnaire was also used to extrapolate core findings of this research. This research provides a significant contribution of POE result towards improving indoor environment to ceremonial and public buildings in Jordan.展开更多

These rocks consist mainly of limestone, marls, chalk, biogenic chert and phosphate of primarily marine origin. Age determination of these rocks was based on the abundance of macro and microfossil content. Man researchers subdivided the Upper Cretaceous succession. The classification of Powell (1989) is considered in this study, particularly for the Belqa Group, which is of Coniacian to Maastrichtian in age. This investigation will focus on the geology of Wadi Es Sir, Umm Ghudran;Amman silicified limestone, and Al Hisa phosphorite formations, that belong to Ajlun and Belqa Groups respectively. Moreover, sedimentary structures, lithological characteristics Microfacies types and fossil content were evaluated. Using the lithostratigraphy and the fossil content of those formations, 6 Microfacies types were identified. Evaluation of the cross-section, the tectonic processes and the prepared rose diagrams indicate that the study area was affected by compressional as well as by tensional forces. Two major tends of fracturing can be identified in the rose diagrams. The measured physical properties show that the porosity is variable and ranges between 30% and 48%. The bulk density has values between 1.8 and 2.2 g/cm<sup>3</sup>. The different obtained results point out that the studied rocks represent good reservoir.展开更多

The difference between profitability ratios and turnover ratios is the fact that turnovers are more specific. While profitability ratios measure overall performance in terms of profits, asset utilization ratios focus on specific measurements within the business） We conduct this study to verify the impact of turnover ratios on Jordanian services sectors＇ performance during the period from 2009 to 2012. The study showed that there is no significant impact of turnover ratios on Jordanian services sectors＇ profitability, and by testing the main and sub hypotheses, the study revealed that there is no significant impact of turnover ratios on Jordanian services sectors＇ return on assets （ROA）, there is no significant impact of working capital turnover on Jordanian services sectors＇ ROA, there is no significant impact of total asset turnover on Jordanian services sectors＇ ROA, and there is no significant impact of fixed asset turnover on Jordanian services sectors＇ ROA. Also, the study showed that there is no significant impact of turnover ratios on Jordanian services sectors＇ return on equity （ROE）, there is no significant impact of working capital turnover on Jordanian services sectors＇ ROE, there is no significant impact of total asset turnover on Jordanian services sectors＇ ROE, and there is no significant impact of fixed asset turnover on Jordanian services sectors＇ ROE. Moreover, the study concluded that the educational services sector has the lowest working capital turnover and healthcare services sector has the highest. In addition, we find that the hotels and tourism sector has the lowest total asset turnover ratio, while the utilities and energy sector has the highest and that the hotels and tourism sector has the lowest fixed asset turnover, while the utilities and energy sector has the highest. The transportation sector has the lowest ROA and technology and communication sector has the highest. Finally, we find that transportation sector has the lowest ROE and the technology and communication sector has the highest.展开更多

Decision makers can achieve extra features of the change in net assets, the firms＇ financial position （liquidity and solvency）, and the firm＇s ability to adapt to changing circumstances by affecting the amount and timing of cash flows. Cash flow statements improve comparability as they are not affected by differing accounting policies used for the same type of transactions or events. This study aims to verify the effect of net working capital （NWC）, as an indicator of a company＇s short-term liquidity or its ability to meet short-term obligations, on Jordanian industrial and energy sectors＇ net operating cash flows （NOCF）. A simple liner regression is used to test a period of 2008-2011 in order to conclude the extent of the effect on industrial and energy sectors. The study showed that there is a significant effect of the independent variable NWC on the dependent variable NOCF among industrial and energy sectors in Jordanian market. Whereas the adjusted R-squared of test is 0.854, changes in NOCF in Jordanian industrial and energy sectors have been described by NWC. Also, the study reached that the utilities and energy sector has the lowest NWC, while the mining and extraction sector has the highest. And, electrical industries sector has the lowest NOCF, while the mining and extraction sector has the highest. Moreover, the study showed that the printing and packaging sector has the lowest NWC, while the mining and extraction sector has the highest. And, glass and ceramic industries sector has the lowest NOCF, while the utilities and energy sector has the highest.展开更多
