Water–Demand Management in the Kingdom of Saudi Arabia for Enhancement Environment

The purpose and the goal of the paper is growing substantially and that is being met through the available scarce and dwindling water resources. The kingdom of Saudi Arabia (KSA) faces an acute water shortage due to arid climate and absence of permanent lakes and rivers. Ever-increasing imbalances are usually met by increasing water supplies, whereas the concepts of water-demand management have not been given due importance and weight age. Meeting the rapidly rising demand with scarce and depleting resources remains the critical issue. The goal of this paper is showing; how Geographical Information Systems(GIS) can be used to support infrastructure  planners and analyst  on a local area. This paper places emphasizes on the urgency of adopting conservation and water-demand management initiatives to maintain demand supply relationship and achieve an acceptable balance between water needs and availability. The kingdom places emphasis on the shift from supply development to demand management to use of critical and non-renewable water resources efficiently. The paper suggests that the water-use-efficiency (WUE) in various sectors can be enhanced and improved in the kingdom. The paper presents an overview of the country’s water resources and issues related to water. Some possible conservation and remedial measures particularly in the agricultural sector-the largest and most inefficient user of water have been suggested. The objective of this paper is to safeguard and conserve this precious natural resource through environmental friendly technologies for the future generations to come. It is presumed that water resources can be managed on sustainable basis by devising and employing environmental friendly technologies including water conservation measures. The usefulness of these measures can be supplemented through the vibrant and viable extension and education initiatives and capacity building programs. In this work, three sets applications of GIS models have been produced. The geodatabase of district  areas  in Saudi Arabia including these layers of  Area, Subarea, Cites, water in land, water area, land cover, roads, rail roads, elevations. Keywords: Water Demand, Water Resources, GIS, Highway Street, XML Schema

An Assessment of Rewards and Motivation Strategies as Predictors of Employee Job Satisfaction in the Banking Industry in Kenya

This study sought to assess the prediction effect of reward and Motivation strategies on job satisfaction in the Commercial Banks in Kenya. The sample of the study comprised of 78 respondents being 28 managerial staff and 50 line employees drawn from Commercial Banks in Western Kenya. Data was collected by use of questionnaires and interview schedule. Statistically quantitative data was analyzed using descriptive as well as inferential statistics. Study findings revealed a statistically significant relationship between employee reward and job satisfaction and a significant relationship between employee motivation and job satisfaction. Findings of this study have provided vital and relevant information to stakeholders in the banking industry in Kenya and beyond on how reward and motivation strategies can be harnessed to bring about employee job satisfaction for improved organizational performance. The study has also stretched the frontiers of knowledge on the relationship between employee motivation and resultant occupational attitudes. Keywords: Rewards, Motivation, Job Satisfaction, Commercial Bank

Understanding the stumbling blocks of Italian higher education system:A process mining approach

Nowadays universities strive to continuously enhance their educational programs to improve both the quality and quantity of their graduates. This is a sensitive problem, especially for Italian universities where only 30% of the students enrolled at the university succeed in graduating within a year after the normal duration of the study plan. Over the last few years, the Italian Ministry of University and Education has introduced several indicators to assess students’ careers and help universities identify possible criticality in their study programs. However, these indicators only provide a high-level overview of the graduation process without providing insights into students’ failure. To address this issue, in this work, we propose to model a study program as a process and exploit process analysis techniques to assess students’ performance. These techniques allow delving into students’ careers, thus enabling the investigation of their failures and delays. The findings obtained by applying our approach to the Bachelor program of an Italian university allowed us to determine common bottlenecks that seem to have an impact on students’ graduation time. Moreover, we were able to determine and compare the career paths of successful and late students. The insights gathered by our analysis can be used to support university personnel in delving into factors causing some exams to be a bottleneck, as well as to determine potential improvements in the overall curricula.</p

Isolation of Methicillin-Resistant Coagulase-Negative Staphylococcus (MRCoNS) from a fecal-contaminated stream in the Shenandoah Valley of Virginia

Staphylococcus is comprised of 41 known species, of which 18 can colonize humans. Despite the prevalence of infectious Staphylococcus within hospital settings and agriculture, there are few reports of Staphylococcus in natural bodies of water. A recent study by the US Food and Drug Administration found substantial contamination of poultry and other meats with Staphylococcus. We hypothesized that intensive farming of poultry adjacent to streams would result in contaminated runoff, resulting in at least transient occurrence of Staphylococcus spp. in stream waters and sediments. In this study, we sought to determine whether Staphylococcus occurs and persists within Muddy Creek, a stream located in Hinton, Virginia that originates at the Appalachian Mountains of Virginia and runs through various agricultural fields and adjacent to a poultry processing plant in the central Shenandoah Valley. Five different Staphylococcus spp. were detected in water and sediment from Muddy Creek. Mannitol Salt Agar (MSA) was used to isolate eleven Staphylococcus from both water and sediment. These isolates were Gram-positive, catalase-positive, and oxidase-negative cocci that were capable of fermenting mannitol. In addition, a method for screening putative staphylococci species from stream water and sediment was developed. Ten out of the eleven tested isolates were oxacillin resistant (now used to identify phenotypic methicillin-resistance) using a Kirby Bauer disc diffusion test. Furthermore, the isolates were susceptible to trimethoprim/sulfamethoxazole, tetracycline, and gentamicin while two of the isolates were resistant to erythromycin. Additionally, the BOX-PCR repetitive sequence fingerprinting method verified the presence of nine different strains among the isolates. Sequencing of the 16S rRNA gene identified five of the isolates as Staphylococcus equorum. The Biolog identification protocol further identified the remaining isolates as Staphylococcus xylosus, Staphylococcus lentus, Staphylococcus succinus, and Staphylococcus sciuri. Finally, polymerase chain reaction amplification (PCR) confirmed that ten of the eleven isolates harbored the mecA gene known to confer methicillin-resistance. Overall, the occurrence of coagulase-negative staphylococci (MRCoNS) in stream water and sediment represents a potential environmental and human health concern
