Measuring the Performance of Islamic Banks by Adapting Conventional Ratios

One consequence of the current financial crisis is that many countries began to reevaluate their financial systems and recognize its flaws and drawbacks. They also began the search for alternative systems for their economies; one of the proposed systems is the current Islamic financial model. This model is still in its infancy and many modifications and additions are required. It also lacks the necessary financial performance measurement tools similar to those used by conventional banks for managers and investors alike. This paper evaluates this lack of performance measures. It then adapts a currently applied ROE Analysis Tool used in conventional banks, to the currently established model of Islamic Banks and tests its applicability and evaluates its usefulness. The findings suggest that such an adapted model would be quite successful for use in Islamic banks and would offer much better analysis and basis of comparison within the Islamic financial system. It also suggests that much of the previously measured performance of Islamic Banks is unsound and should be revised for accuracy and reliability because of the flawed methods used for measurement in the first place.Performance measurement, ratio analysis, ROE, Islamic banks

The Effect of Mergers and Acquisitions on Bank Performance in Egypt

Recent economic reforms in Egypt have significantly improved its macroeconomic indicators and financial sector. Banks have witnessed significant merger and acquisition activity as a result of these reforms in attempts to privatize and strengthen the banking sector. This study measures the performance of Egyptian banks that have undergone mergers or acquisitions during the period 2002-2007. This is done by calculating their return on equity using the Basic ROE Scheme in order to determine the degree of success of banking reforms in strengthening and consolidating the Egyptian banking sector. Our findings indicate that not all banks that have undergone deals of mergers or acquisitions have shown significant improvements in performance and return on equity when compared to their performance before the deals. Furthermore, extensive analysis was performed yielding the same results. It was concluded that mergers and acquisitions have not had a clear effect on the profitability of banks in the Egyptian banking sector. They were only found to have minor positive effects on the credit risk position. These findings do not support the current process of financial consolidation and banking reforms observed in Egypt, and provide weak evidence to support their constructive role in improved bank profitability and economic restructure.Mergers and Acquisitions, Egypt, Banks, ROE, Performance Measurement, Reforms, ROA

Enhanced Oil Recovery Using Seismic Excitation

The major factor in increasing residual oil recovery depends on controlling interfacial forces inside the reservoir. In a water wet system, a thin water film covers the matrix material and water forms a continuous phase. When the oil saturation drops below some critical value, it forms a droplets and become dispersed in the water phase. To pass the dispersed droplets through pore throat constrictions, large forces are required. Such large force can be provided by water injection. However, since water is the continuous phase, it bypasses the oil droplets instead of pushing them through the constrictions. A numerical study was performed in order to understand the effect of the seismic waves on the oil droplet trapped in capillary pore throat. The results show that periodic variation of pressure at the pore throat has a nudging effect on the trapped oil drops and in the process it squeezes them through the pore throat constriction

The Relationship between Unemployment and Inflation in Sudan: An Empirical Analysis, 1992-2015

This study investigated from an empirical point of view, the relationship between unemployment and inflation in Sudan during the period 1992-2015. Annual time series data has been used in the analysis to estimate the model for the period under consideration. Data for the study were obtained from central bank of Sudan and central bureau of statistics. Using these data, Granger test is applied to estimate the causal relationship between unemployment and inflation. The results provided that unemployment does not Granger cause Inflation, and inflation dose not Granger cause unemployment. Thus, there is no causality relationship between inflation rates and unemployment rates in Sudan from 1992-2015

PHYSICIAN AS A MANAGER: PERSONAL AND MANAGERIAL CHARCTERISTICS, SAUDI ARABIA

BACKGROUND: The emergence of physicians' roles in key adminstrative positions within many King Saudi Arabia health care organizations has represented a major change in the medical profession over the last two decades. This have created a need for physicians who are willing to assume a high level of responsibility for managing evovling health care organizations. The study explores the perception of physician managers regarding their work, personal and managerial characteristics. METHODS: The data for this study were obtained from a sample of 200 physicians working in management positions in different health care organizations in Riyadh. Physicians were selected at random with probability proportional to size from a list containing managers in all health care organization to participate in the study RESULTS: Our results indicated that physician managers lack admistration skills. No formal training in medical adminstration and management because management principles are not integrated in the medical context and the majority were experienced in management for less than four years.  Very few possess the technical comptencies such as strategic planning, financial and economics knowledge. Boredom with medical practice, improvement of personal position and encouragement from others are related to being older, having more years in medicine and interest in medicine is reduced. The finding also supported the notion that physician manager can maintain stable levels of loyality to professional interest and organization. This dual commitment is related to work-relate characteristics involving sharing his time favorably to management job and to patient care. Recommendation: To improve their management skills physicians can benefit from mamagement education programs such as those offered by King Saud University

Effectiveness and suitability of vapor heat treatment in disinfestation of export mango fruit, cultivar Abu Samaka, from fruit flies

    Sudan has a great potential for the export of mango (Mangifera Indica L.) but fruit flies, mainly Bactrocera dorsalis (Hendel), Ceratitis cosyra (Walker), C. capitata (Wiedmann) and B. zonata (Saunders) are threatening the export industry. The countries importing mango require disinfestation treatment against fruit flies as a quarantine regulation. Effectiveness and suitability of vapor heat treatment (VHT) for disinfestation of the Sudanase mango cultivar Abu Samaka were undertaken in this study. In the VHT, the relative humidity of the treatment chamber was maintained at 99.7% and the temperature of the fruit pulp was raised gradually to reach 46.7°C in 5 hours then kept at this degree for 30 minutes before hydro-cooling for 20 minutes. For evaluation of the effectiveness of the treatment, naturally and artificially infested fruits were examined for fruit flies after treatment and compared with their respective untreated samples. To assess suitability of the treatment with respect to quality of the mango fruit, respiration rate, peel color, weight loss, flesh firmness, ascorbic acid content, total soluble solids, titratable acidity and reducing sugars were measured in the treated and control fruits.  The VHT was found effective in disinfestation of the mango cultivar Abu Samka from fruit flies and did not adversely affect the fruit market quality and increased the shelf life

Enhanced oxygen evolution reaction on polyethyleneimine functionalized graphene oxide in alkaline medium

Practical applications of metal free catalysts are hindered by their innate poor stability for electrocatalytic application. Accordingly, in this study, synthesis and functionalization of graphene oxide via a modified Tour's method (GOT) with different amine containing molecules results in excellent catalytic performance and stability toward OER in alkaline medium. The as-synthesized polyethyleneimine GOT electrode (P-GOT), produced current densities of 10, 50 and 100 mA/cm2 at overpotentials of 240, 350 and 420 mV, respectively, with small Tafel slope of 47 mV/dec. The X-ray diffraction analysis (XRD), Raman spectroscopy and X-ray photoelectron spectroscopy (XPS) analysis confirms the successful functionalization of GOT by ethylenediamine (E) and polyethyleneimine (P) molecules, respectively. Morphological studies based on field emission scanning electron microscopy (FESEM) confirm that the modification via covalent bonding preserved the original wrinkled and layered structure of GOT. The P-GOT with cross-linked amine can expose more active sites and is not easy to peel off, which corresponds to attaining lower charge transfer resistance (1.01Ω cm2) and remarkable current stability in 1.0 M KOH solution, compared to the pristine GOT and E-GOT electrodes. From this perspective, our results therefore provide a valuable route for development and practical application of metal free catalytic materials for water oxidation reaction

Antimicrobial resistance among migrants in Europe: a systematic review and meta-analysis

BACKGROUND: Rates of antimicrobial resistance (AMR) are rising globally and there is concern that increased migration is contributing to the burden of antibiotic resistance in Europe. However, the effect of migration on the burden of AMR in Europe has not yet been comprehensively examined. Therefore, we did a systematic review and meta-analysis to identify and synthesise data for AMR carriage or infection in migrants to Europe to examine differences in patterns of AMR across migrant groups and in different settings. METHODS: For this systematic review and meta-analysis, we searched MEDLINE, Embase, PubMed, and Scopus with no language restrictions from Jan 1, 2000, to Jan 18, 2017, for primary data from observational studies reporting antibacterial resistance in common bacterial pathogens among migrants to 21 European Union-15 and European Economic Area countries. To be eligible for inclusion, studies had to report data on carriage or infection with laboratory-confirmed antibiotic-resistant organisms in migrant populations. We extracted data from eligible studies and assessed quality using piloted, standardised forms. We did not examine drug resistance in tuberculosis and excluded articles solely reporting on this parameter. We also excluded articles in which migrant status was determined by ethnicity, country of birth of participants' parents, or was not defined, and articles in which data were not disaggregated by migrant status. Outcomes were carriage of or infection with antibiotic-resistant organisms. We used random-effects models to calculate the pooled prevalence of each outcome. The study protocol is registered with PROSPERO, number CRD42016043681. FINDINGS: We identified 2274 articles, of which 23 observational studies reporting on antibiotic resistance in 2319 migrants were included. The pooled prevalence of any AMR carriage or AMR infection in migrants was 25·4% (95% CI 19·1-31·8; I2 =98%), including meticillin-resistant Staphylococcus aureus (7·8%, 4·8-10·7; I2 =92%) and antibiotic-resistant Gram-negative bacteria (27·2%, 17·6-36·8; I2 =94%). The pooled prevalence of any AMR carriage or infection was higher in refugees and asylum seekers (33·0%, 18·3-47·6; I2 =98%) than in other migrant groups (6·6%, 1·8-11·3; I2 =92%). The pooled prevalence of antibiotic-resistant organisms was slightly higher in high-migrant community settings (33·1%, 11·1-55·1; I2 =96%) than in migrants in hospitals (24·3%, 16·1-32·6; I2 =98%). We did not find evidence of high rates of transmission of AMR from migrant to host populations. INTERPRETATION: Migrants are exposed to conditions favouring the emergence of drug resistance during transit and in host countries in Europe. Increased antibiotic resistance among refugees and asylum seekers and in high-migrant community settings (such as refugee camps and detention facilities) highlights the need for improved living conditions, access to health care, and initiatives to facilitate detection of and appropriate high-quality treatment for antibiotic-resistant infections during transit and in host countries. Protocols for the prevention and control of infection and for antibiotic surveillance need to be integrated in all aspects of health care, which should be accessible for all migrant groups, and should target determinants of AMR before, during, and after migration.

Surgical site infection after gastrointestinal surgery in high-income, middle-income, and low-income countries: a prospective, international, multicentre cohort study

Background: Surgical site infection (SSI) is one of the most common infections associated with health care, but its importance as a global health priority is not fully understood. We quantified the burden of SSI after gastrointestinal surgery in countries in all parts of the world. Methods: This international, prospective, multicentre cohort study included consecutive patients undergoing elective or emergency gastrointestinal resection within 2-week time periods at any health-care facility in any country. Countries with participating centres were stratified into high-income, middle-income, and low-income groups according to the UN's Human Development Index (HDI). Data variables from the GlobalSurg 1 study and other studies that have been found to affect the likelihood of SSI were entered into risk adjustment models. The primary outcome measure was the 30-day SSI incidence (defined by US Centers for Disease Control and Prevention criteria for superficial and deep incisional SSI). Relationships with explanatory variables were examined using Bayesian multilevel logistic regression models. This trial is registered with ClinicalTrials.gov, number NCT02662231. Findings: Between Jan 4, 2016, and July 31, 2016, 13 265 records were submitted for analysis. 12 539 patients from 343 hospitals in 66 countries were included. 7339 (58·5%) patient were from high-HDI countries (193 hospitals in 30 countries), 3918 (31·2%) patients were from middle-HDI countries (82 hospitals in 18 countries), and 1282 (10·2%) patients were from low-HDI countries (68 hospitals in 18 countries). In total, 1538 (12·3%) patients had SSI within 30 days of surgery. The incidence of SSI varied between countries with high (691 [9·4%] of 7339 patients), middle (549 [14·0%] of 3918 patients), and low (298 [23·2%] of 1282) HDI (p < 0·001). The highest SSI incidence in each HDI group was after dirty surgery (102 [17·8%] of 574 patients in high-HDI countries; 74 [31·4%] of 236 patients in middle-HDI countries; 72 [39·8%] of 181 patients in low-HDI countries). Following risk factor adjustment, patients in low-HDI countries were at greatest risk of SSI (adjusted odds ratio 1·60, 95% credible interval 1·05–2·37; p=0·030). 132 (21·6%) of 610 patients with an SSI and a microbiology culture result had an infection that was resistant to the prophylactic antibiotic used. Resistant infections were detected in 49 (16·6%) of 295 patients in high-HDI countries, in 37 (19·8%) of 187 patients in middle-HDI countries, and in 46 (35·9%) of 128 patients in low-HDI countries (p < 0·001). Interpretation: Countries with a low HDI carry a disproportionately greater burden of SSI than countries with a middle or high HDI and might have higher rates of antibiotic resistance. In view of WHO recommendations on SSI prevention that highlight the absence of high-quality interventional research, urgent, pragmatic, randomised trials based in LMICs are needed to assess measures aiming to reduce this preventable complication

Immunoglobulin, glucocorticoid, or combination therapy for multisystem inflammatory syndrome in children: a propensity-weighted cohort study

Background: Multisystem inflammatory syndrome in children (MIS-C), a hyperinflammatory condition associated with SARS-CoV-2 infection, has emerged as a serious illness in children worldwide. Immunoglobulin or glucocorticoids, or both, are currently recommended treatments. Methods: The Best Available Treatment Study evaluated immunomodulatory treatments for MIS-C in an international observational cohort. Analysis of the first 614 patients was previously reported. In this propensity-weighted cohort study, clinical and outcome data from children with suspected or proven MIS-C were collected onto a web-based Research Electronic Data Capture database. After excluding neonates and incomplete or duplicate records, inverse probability weighting was used to compare primary treatments with intravenous immunoglobulin, intravenous immunoglobulin plus glucocorticoids, or glucocorticoids alone, using intravenous immunoglobulin as the reference treatment. Primary outcomes were a composite of inotropic or ventilator support from the second day after treatment initiation, or death, and time to improvement on an ordinal clinical severity scale. Secondary outcomes included treatment escalation, clinical deterioration, fever, and coronary artery aneurysm occurrence and resolution. This study is registered with the ISRCTN registry, ISRCTN69546370. Findings: We enrolled 2101 children (aged 0 months to 19 years) with clinically diagnosed MIS-C from 39 countries between June 14, 2020, and April 25, 2022, and, following exclusions, 2009 patients were included for analysis (median age 8·0 years [IQR 4·2–11·4], 1191 [59·3%] male and 818 [40·7%] female, and 825 [41·1%] White). 680 (33·8%) patients received primary treatment with intravenous immunoglobulin, 698 (34·7%) with intravenous immunoglobulin plus glucocorticoids, 487 (24·2%) with glucocorticoids alone; 59 (2·9%) patients received other combinations, including biologicals, and 85 (4·2%) patients received no immunomodulators. There were no significant differences between treatments for primary outcomes for the 1586 patients with complete baseline and outcome data that were considered for primary analysis. Adjusted odds ratios for ventilation, inotropic support, or death were 1·09 (95% CI 0·75–1·58; corrected p value=1·00) for intravenous immunoglobulin plus glucocorticoids and 0·93 (0·58–1·47; corrected p value=1·00) for glucocorticoids alone, versus intravenous immunoglobulin alone. Adjusted average hazard ratios for time to improvement were 1·04 (95% CI 0·91–1·20; corrected p value=1·00) for intravenous immunoglobulin plus glucocorticoids, and 0·84 (0·70–1·00; corrected p value=0·22) for glucocorticoids alone, versus intravenous immunoglobulin alone. Treatment escalation was less frequent for intravenous immunoglobulin plus glucocorticoids (OR 0·15 [95% CI 0·11–0·20]; p<0·0001) and glucocorticoids alone (0·68 [0·50–0·93]; p=0·014) versus intravenous immunoglobulin alone. Persistent fever (from day 2 onward) was less common with intravenous immunoglobulin plus glucocorticoids compared with either intravenous immunoglobulin alone (OR 0·50 [95% CI 0·38–0·67]; p<0·0001) or glucocorticoids alone (0·63 [0·45–0·88]; p=0·0058). Coronary artery aneurysm occurrence and resolution did not differ significantly between treatment groups. Interpretation: Recovery rates, including occurrence and resolution of coronary artery aneurysms, were similar for primary treatment with intravenous immunoglobulin when compared to glucocorticoids or intravenous immunoglobulin plus glucocorticoids. Initial treatment with glucocorticoids appears to be a safe alternative to immunoglobulin or combined therapy, and might be advantageous in view of the cost and limited availability of intravenous immunoglobulin in many countries.
