Purpose Islamic banking industry with all of its exponential growth and global recognition has been under criticism for the past two decades. However, the problem signifies further when such criticism is made from within the organization and is well supported by outside (the customers). The purpose of this study is to provide a coherent exploration to investigate the factors that polarize its employees and customers across many parts of the world. Design/methodology/approach To investigate the phenomenon, a total of 30 responses were taken through interviews 15 each from customers and employees. Afterwards, the data was analysed and summarized into two categories. In doing so, the top five Malaysia’s Islamic banks were shortlisted to collect data from employees and customers. Findings A detailed thematic analysis resulted in six themes (Contradiction between theory and practice, Islamic banking knowledge and awareness, inadequate Shariah training, employees’ background, Shariah compliance, Islamic banking benefits) for employees and five (Islamic banking benefits, applying Shariah in Islamic banking, knowledge of Islamic banking, Islamic banking promotion, Islamic banking employees’ behaviour) for customers, respectively. Research limitations/implications The results have stronger implications for both practice and theory as organizations can assess stakeholders and their perceptions about Islamic banking. Another implication is the comparative examination of employees and customers which can potentially affect decision and policy making in Islamic banks. Islamic banks can also address employment-related issues related to employees’ behaviour vis-à-vis marketing-related problems faced by its customers that will ultimately improve its global market share and strategic positioning. Originality/value The study is based on the importance of Islamic banking in Malaysia and explores the factors that potentially create a positive or negative insight into Islamic banking – both in employees and customers.

AbstractAlcaligenes faecalis is a heterotrophic nitrifying bacterium that oxidizes ammonia and generates nitrite and nitrate. When A. faecalis was cultivated in a medium containing pyruvate and ammonia as the sole carbon and nitrogen sources, respectively, high concentrations of nitrite accumulated in the medium whose carbon/nitrogen (C/N) ratio was lower than 10 during the exponential growth phase, while the accumulation was not observed in the medium whose C/N ratio was higher than 15. Comparative transcriptome analysis was performed using nitrifying and non-nitrifying cells of A. faecalis cultivated in media whose C/N ratios were 5 and 20, respectively, to evaluate the fluctuations of gene expression during induction of heterotrophic nitrification. Expression levels of genes involved in primary metabolism did not change significantly in the cells at the exponential growth phase under both conditions. We observed a significant increase in the expression levels of four gene clusters: pod cluster containing the gene encoding pyruvic oxime dioxygenase (POD), podh cluster containing the gene encoding a POD homolog (PODh), suf cluster involved in an iron-sulfur cluster biogenesis, and dnf cluster involved in a novel hydroxylamine oxidation pathway in the nitrifying cells. Our results provide valuable insight into the biochemical mechanism of heterotrophic nitrification.

mRNA methylation is an important regulator of many physiological processes in eukaryotes but has not been studied in depth in prokaryotes. In contrast to the large number of eukaryotic mRNA modifications that have been described, N6-methyladenosine (m6A) is the only modification of bacterial mRNA identified to date. Here, we used a gel electrophoresis-based RNA separation method and quantitatively analyzed the mRNA-specific modification profile of Escherichia coli using mass spectrometry. In addition to m6A, we provide evidence for the presence of 7-methylguanosine (m7G), and we found first hints for 5-methylcytidine (m5C), N6,N6-dimethyladenosine (m6,6A), 1-methylguanosine (m1G), 5-methyluridine (m5U), and pseudouridine (Ψ) in the mRNA of E. coli, which implies that E. coli has a complex mRNA modification pattern. Furthermore, we observed changes in the abundance of some mRNA modifications during the transition of E. coli from the exponential growth to the stationary phase as well as upon exposure to stress. This study reveals a previously underestimated level of regulation between transcription and translation in bacteria.

Education under the Franco regime was divided into two clearly differentiated periods. The first 2 decades of the regime (1936–1959) were characterized by a policy inspired by a radical rejection of the modernization program designed by liberal Spain and especially of the progressive and secular policy of the Second Republic. The principles that formed the backbone of this first stage were a forced re-Christianization of education, a renewed role for ideologization and deprofessionalization of teachers, a contraction of the school network, and an emphasis on privatization. During this period, education was subordinated to the Catholic Church, with the state assuming a subsidiary position that allowed for an outstanding expansion of religious schools. At the beginning of the 1960s, there was a Copernican turn in the regime’s educational policy as a result of the directives of international organizations that sought economic development. The state abandoned its subsidiarity, and throughout the 1960s promoted an exponential growth of the country’s rickety education system. This new policy culminated in a general reform of the education system, the General Education Act of 1970, which put an end to the dual system inherited from the 19th century, and introduced comprehensive education in Spain.

Abstract: Many statistical and mathematical models of growth are developed in the literature and effectively applied to various conditions in the existent world that involve many research problems in the different fields of applied statistics. Nevertheless, still, there is an equally large number of conditions, which have not yet been mathematically or statistically modeled, due to the complex situations or formed models are mathematically or statistically inflexible. The present study is based on mathematical and stochastic growth models. The specification of both the growth models is depicted. A detailed study of newly modified growth models is mentioned. This research will give substantial information on growth models, such as proposed modified exponential growth models and their specifications clearly motioned which gives scope for future research.

PurposeThe purpose of this paper is to analyze and map the main areas of the Circular Economy literature of the first two decades of 21st century, offering a broad vision about the growth of the theme during these years.Design/methodology/approachThe research was divided into two stages: the first was a systematic review of literature and the second consisted on generation and analysis of bibliographic maps.FindingsThe publication indicates the prominence of China and European Union countries in the production of articles about Circular Economy. Furthermore, the topic is restricted to academic area, and that research on Circular Economy is still very focused on theory studies, even with exponential growth in the number of published articles about the theme since 2015. Finally, it also provides a collection of information as the principal authors, the most cited publications, citations, co-citations and countries that have most published beyond which are the most discussed topics.Research limitations/implicationsA possible limitation of the research is that it was performed only in the Scopus database. It may be suggested as future searches that other databases are included as well, and another suggestion is to reduce the time period between research samples due to the exponential increase in the number of publications and topics discussed lately.Practical implicationsThe results of this paper can guide future researches about the development of Circular Economy during the next decades or years and serve as a facilitator for researchers and for managers that want to know more about the topic.Originality/valueA mapping of the principal players and main discussions about Circular Economy made in the first two decades of the 21st century and an analysis about the growth and changes about the theme.

New waves of the COVID-19 pandemic in Ukraine, which began in the summer of 2021, and after holidays in the middle of October 2021, were characterized by almost exponential growth of smoothed daily numbers of new cases. This is a matter of great concern and the need to immediately predict the epidemic dynamics in order to assess the possible maximum values of new cases, the risk of infection and the number of deaths. The generalized SIR-model and corresponding parameter identification procedure was used to simulate and predict the dynamics of two new epidemic waves in Ukraine and one in the whole world. Results of calculations show that new cases in Ukraine will not stop to appear before November 2022. If the global situation with vaccination, testing and treatment will not change, the pandemic could continue for another ten years.

The present paper is devoted to the study of the possibility of estimating the reproductive potentials of wild ungulate populations, and possibly other large mammals, by the time series of their numbers. We have found out that this is possible, which is confirmed by the high quality of approximation of the time series of abundance by logistic curves, and the corresponding coefficients of their determination for different species ranged from 75 to 96%. For such calculations, one circumstance is necessary, which is that the population of the studied species has been briefly exposed to some unfavorable factor causing a significant reduction in its numbers with subsequent restoration to the previous level, or the time series should contain a well-expressed and extended section of the transition of the population from some lower level to the upper level of the population, passing into a stationary state. The values of the maximum exponential growth rates of ungulate populations that we obtained do not fundamentally differ from the data available in other researchers’ works. In addition, it should be borne in mind that our method for assessing the reproductive potentials of ungulates is statistical, with features accompanying all such methods, for example, in the presence of statistical errors in all determined parameters. However, the evaluation of the magnitude of these errors is a topic for a separate study.
