This article first uses the gray correlation analysis combined with the gravitational search algorithm model to model the time series linearly. In this way, the predicted value of the GEM stock price ...is obtained. The simulation analysis of the calculation example found that the average relative error of the prediction result of our proposed model is 0.095 and the operation efficiency is high.
Aiming at the increasing research demand of the resonance properties of semantic waves in quantitative analysis of English corpus, this paper constructs a three-dimensional integrated fractal model ...of semantic waves, and extends the transformation of semantic waves in system functional linguistics to the lexical grammar level. The in-depth analysis provides objective and explicit analysis and identification criteria for the study of semantic waves in the legalized code theory. Through the experimental method, the type resonance characteristics between different types of semantic waves in English popular science discourses are investigated. The experimental results show that the frequency of peaks and troughs varies from 2 to 153 based on different characters, and the construction of different types of semantic waves presents the legalized communication process of knowledge popularization, embodies the social education essence of popular science practice, and is the basis of popular science discourse. The legal representation of persuasive and informative discourse features in the process of knowledge construction provides a reference standard.
It is more difficult to give Laplace transform directly in a defined form or derive it by Fourier transform in mathematics teaching. The article gives a solution for solving high exponential series ...sum by using Laplace transform. With the help of Laplace transform, calculus operations can be transformed into complex plane algebra operations. The application of the algorithm to the option hedging strategy verifies the applicability of the algorithm proposed in this article.
This study aims to empirically examine the financial and operating performance of Egyptian privatised companies. The study compares the pre- and post-privatisation financial and operating performance ...of 60 companies from Egypt that have experienced privatisation through different methods during the period from 1991 and 1997. There were significant increases in the mean and median levels of profitability, operating efficiency, capital investment, output and dividends for the whole sample of companies after privatisation. There were significant decreases in the mean and median of both leverage ratios and employment levels. Further analysis was also undertaken using the three different background characteristics (i.e. size of company, type of industry and privatisation methods). No significant differences were detected in the Kruskal Wallis test analysis of privatisation methods. The Wilcoxon test, the Proportion test and the Kruskal Wallis test analyses for the company size and industry type revealed some significant results. Overall, the findings do seem to support the broad benefits of the Egyptian privatisation programme and the improvements in the financial and operating performance of the privatised companies.
Purpose: This research aims to enhance practical organizational practices and academic research literature by critically investigating the latest findings in cybersecurity culture research through a ...systematic review of relevant literature and research.
Theoretical Framework:This work seeks to summarize key research developments in a research area that remains challenging for companies as they seek to build strong security cultures to protect their information (Tripwire, 2020). And reviewing the legal regulations that must be trained to protect institutions from cyber threats in the Kingdom of Bahrain and Saudi Arabia.
Design/Methodology/Approach: The methodology of this study implements a systematic literature review to assess the main components of cybersecurity culture and what good practice can help to build it professionally.
Findings: The main results find that current literature must move from a technical approach to information security to a socio-cultural one. Also, this study predicts that cybercrime will increase dramatically and cost the world trillions annually.
Research Practical and Social Implications: this study attempts to define human resource management's role in cybersecurity awareness training and therfore the managers can deveplo the necessary rules to secure the organizational information.
Originality/Value: The study is within the first studies to be conducted in GCC countries. Moreover, the to build a cyber security culture is unique topic add on to the academic knowledge. Also, can motivate the future studies to focus on efficiently organizing security procedures and enhancing security readiness appraisal consequences by providing more perceptions of imminent threats and security hazards.
The existence of international students makes an investigation of the impact on a country’s economy topical. Despite the complexity of measuring the economic impact of education tourism, many ...countries have conducted analyses to justify that international higher education students have a positive impact on the public economy. In the Gulf States, efforts to reform and modernize higher education to create knowledge-based societies are ongoing. Member states of the Gulf Cooperation Council (GCC) share a regional vision to make the Arab Gulf a hub for a world-class education. Arab higher education systems that were long characterized by mass production of graduates and incremental support from the state are now shifting to new Western models of higher education. Several factors, including the development of the knowledge economy, massive access to higher education and increasing higher education differentiation are contributing to this push. To achieve this vision, the Gulf States have adopted the Western research university model by hosting international branch campuses (IBCs) in the region. GCC governments have also embraced study abroad scholarship programs that sponsor large numbers of Gulf nationals to study in Western universities.
