Crosslinked chitosan-ethylene glycol diglycidyl ether (CTS-EGDE) was modified by loading fly ash (FA) particles into its polymeric matrix to improve the adsorptive removal of reactive red 120 (RR120) ...dye. The Box–Behnken design was used to assist in the tuning of optimum synthesis and adsorption conditions, such as the loading ratio of FA particles (A: 0–50%), adsorbent dose (B: 0.02–0.08 g), solution pH (C: 4–10), temperature (D: 30 °C–60 °C), and time (E: 20–60 min). The highest removal rate (98.8%) of 50 mg/L RR120 dye was achieved under the following conditions: FA loading, 25% (CTS-EGDE/FA-25); adsorbent dose, 0.05 g; solution pH, 4; temperature, 60 °C; and time, 40 min. The maximum adsorption capacity of CTS-EGDE/FA-25 for RR120 was 220 mg/g at 60 °C. This work provides insights into the optimization of the synthesis of composite materials, which can potentially be applied in wastewater treatment.
•This study discusses research areas related to the impact of Big Data on accounting practice and theory.•The study presents several potential convergence points between Big Data and different ...accounting techniques and theories.•We argue that there is a lack of empirical research examining the consequences of “Big Data adoption” in accounting and propose several research questions that offer venues for future research.•We present helpful insights to members of the accounting and auditing community on the potential of Big Data.
This study aims to develop accounting standards, curriculums, and research to cope with the rapid development of big data. The study presents several potential convergence points between big data and different accounting techniques and theories. The study discusses how big data can overcome the data limitations of six accounting issues: financial reporting, performance measurement, audit evidence, risk management, corporate budgeting and activity-based techniques. It presents six exciting research questions for future research. Then, the study explains the potential convergence between big data and agency theory, stakeholders theory, and legitimacy theory. This theoretical study develops new convergence points between big data and accounting by reviewing the literature and proposing new ideas and research questions. The conclusion indicates a significant convergence between big data and accounting on the premise that data is the heart of accounting. Big data and advanced analytics have the potential to overcome the data limitations of accounting techniques that require estimations and predictions. A remarkable convergence is argued between big data and three accounting theories. Overall, the study presents helpful insights to members of the accounting and auditing community on the potential of big data.

"The book engages complex processes such as transnationalism, (im)migration, cultural flow, and diaspora in an effort to expand current theoretical approaches to language choice and agency, speech ...style and stylization, codeswitching and language mixing, crossing and sociolinguistic variation, and language use and globalization. Moving throughout the Global Hip Hop Nation, through scenes as diverse as Hong Kong's urban center, Germany's Mannheim inner-city district of Weststadt, the Brazilian favelas, the streets of Lagos and Dar es Salaam, and the hoods of the San Francisco Bay Area, this global intellectual cipha breaks new ground in the ethnographical study of langauge and popular culture."--BOOK JACKET.
This open access Regional Reader describes population movement circulating within the Mediterranean area, for any reason or from any region, be them European, African, Asian or originating from any ...of the Mediterranean shores. It showcases a plurality of approaches to and applications of Mediterranean migration, contributing to a regional approach to migration studies, thereby defending this regional approach by scaling Mediterranean migration issues. This book covers a large set of questions related Mediterranean migrations to the migration research agenda, such as: market and economy, politics and policies, super-diversity and intersectionality, media, society, welfare and the environment through five main parts: Geo-political Mediterranean Relations, Governance, Policies and Politics, Mobility drivers and Agency, Cities, History and Social Transformations, and Economy and Labour Markets. This Regional Reader provides an interesting read to scholars, researchers, but also policy makers and civil society organizations’ high representatives, international foundations and institutions interested in linking the Mediterranean and migration.
This study aims to introduce a proposed model for transforming the Palestine Polytechnic University (PPU) into an entrepreneurial university. Towards that end, a quantitative approach using ...statistical techniques of t test, ANOVA, Kruskal-Wallis test, and Pairwise comparisons supported by explanatory and qualitative discussions were utilized. The main findings show that the applicability of entrepreneurship at PPU was relatively fair for the aspects of the compatibility of curricula with the labor market needs, community relations and partnerships, academic exchange, entrepreneurship culture, entrepreneurial education, and university internationalization. Entrepreneurship as a policy objective was moderately acceptable for university policies and regulations, scientific research and innovation, and university leadership, but the university environment was less than moderate. The findings also show that the university leadership acknowledges the importance of achieving entrepreneurship, while they pay insufficient attention to the academic exchange. Offering other supportive funding resources can accelerate entrepreneurship. Given that, this study is likely to provide a proposed model to transform PPU into an entrepreneurial university and effectively achieve the university's pioneering vision that contributes to the university's development and presents this model to the decision makers.
This paper investigates the question of “will the replacement of the nominal interest rate by the expected Islamic real rate of return have positive consequences on the macroeconomic performance?” ...The study adopts a dynamic small-scale macroeconometric model, which describes the transmission mechanisms among macroeconomic variables under three scenarios about the Islamic real rate of return. The baseline model and the model scenarios are solved using the stochastic simulation. The results of the study indicate that scenario 1 of a zero Islamic real rate of return, or equivalently a zero real interest rate, is superior over other model scenarios, given the priority of the goal of price stability among other objectives of monetary policy.
This study examines whether financial reporting with a specific focus on risk disclosures have a predictive (informative) effect on banks' credit ratings (BCRs) and, consequently, ascertains whether ...governance structures can moderate such an association. Using one of the largest bank‐level datasets collected from 12 Middle East and North African (MENA) countries over the 2006–2013 period to‐date, our findings are as follows. First, we find that risk disclosures have a predictive effect on BCRs. Second, we find that the relationship between risk disclosures and BCRs is contingent on the quality of governance structures. Specifically, we find that the informativeness of risk disclosures on BCRs is higher in banks with larger board size, greater independence, higher government ownership, and better Shariah supervisory board, but lower in banks with greater block ownership, higher foreign ownership and the presence of CEO duality. The central tenor of our findings remains unchanged after controlling for a number of firm‐ and country‐level factors, alternative risk disclosure measures, firm‐ and national‐level governance proxies, different types of banks, and potential endogeneities. The findings have important implications for investors, especially bondholders, standard‐setters, regulators, and central governments.
COVID-19 has caused lockdowns all over the world in early 2020, as a global pandemic. Both theoretical and experimental efforts are seeking to find an effective treatment to suppress the virus. In ...silico drug design can play a vital role in identifying promising drug candidates against COVID-19. Herein, we focused on the main protease of SARS-CoV-2 that has crucial biological functions in the virus. We performed a ligand-based virtual screening followed by a docking screening for testing approved drugs and bioactive compounds listed in the DrugBank and ChEMBL databases. The top 8 docking results were advanced to all-atom MD simulations to study the relative stability of the protein-ligand interactions. MD simulations support that the catalytic residue, His41, has a neutral side chain with a protonated delta position. An absolute binding energy (ΔG) of -42 kJ mol-1 for the protein-ligand (Mpro-N3) complex has been calculated using the potential-of-mean-force (geometrical) approach. Furthermore, the relative binding energies were computed for the top docking results. Our results suggest several promising approved and bioactive inhibitors of SARS-CoV-2 Mpro as follows: a bioactive compound, ChEMBL275592, which has the best MM/GBSA binding energy; the second-best compound, montelukast, is an approved drug used in the treatment of asthma and allergic rhinitis; the third-best compound, ChEMBL288347, is a bioactive compound. Bromocriptine and saquinavir are other approved drugs that also demonstrate stability in the active site of Mpro, albeit their relative binding energies are low compared to the N3 inhibitor. This study provides useful insights into de novo protein design and novel inhibitor development, which could reduce the cost and time required for the discovery of a potent drug to combat SARS-CoV-2.
