Enterprise risk management (ERM) represents a new paradigm that supports organizations in identifying, evaluating, and managing risks. Several factors encourage different organizations, especially banks, to design and apply ERM; among them, the possibility of financial problems and related costs, financial performance decline, growth opportunities, and independence of the board of directors can be pointed out. In addition, applying a suitable risk management strategy is a competitive advantage for supporting companies. Following the previous comprehensive studies, the present study was done by integrating a meta-composition approach and multivariate fuzzy network analysis. In this research, to identify effective factors on ERM based on empirical evidence and selection of studies, description and classification of selected articles, analysis of the content of selected research articles, and finally, the importance and refinement of the identified factors based on the Delphi expert opinion polling technique, and multivariate fuzzy network analysis was discussed. The study aimed to identify and rank the factors affecting the effectiveness of ERM of the firms accepted in selected banks in Iran. While reviewing studies, a semi-structured interview was conducted using an Exploratory-Descriptive Qualitative (EDQ) research design to determine the factors that affect ERM effectiveness. The interviewed experts were comprised of 20 university professors, CEOs, financial analysts of investment and brokerage companies, and senior auditors with accounting and management education. The literature review and the results of the interviews indicate five main themes that classify the factors affecting ERM effectiveness in firms. In this study, key factors were identified, and then the fuzzy Delphi technique was employed to rank and find the weight of the factors. The results showed that corporate governance, financial indicators, environmental indicators, company characteristics, and management indicators effectively enhance ERM's effectiveness. Accordingly, capital market analysts and investment companies should take a broader perspective and make decisions based on companies' financial risks instead of paying attention to companies' profitability and stock price changes. The results demonstrated that five factors determine ERM effectiveness: 1. corporate governance indicators (monitoring the board of directors and ownership structure), 2. Financial indicators (return on assets (ROA), earnings volatility, merger and acquisition (M&A) activities, financial deficiency, and capital opacity), 3. Environmental indicators (performance excellence, industry competition, audit firm credibility, environmental uncertainty, and industry), 4. Firm characteristics (financial leverage, firm size, and growth opportunities), and 5. Management indicators (management career and business diversity).

Embedded options are virtually new instruments identical to options in many aspects except their non-tradable nature. Testing the efficiency of the Variance Gamma and Black-Scholes-Merton model on these instruments would provide a vision of transitioning from the classical model with its deficiency to more intricate models. Considering the complicated nature of the Variance Gamma stochastic process to price options, the Fast Fourier Transform (FFT) method is used in conjunction with the Nelder-Mead Simplex method to calibrate models. This research uses the Fast Fourier Transform (FFT) to price four embedded options with the ticker symbols Hefars912, Heghadir912, Heksho208, and Hetrol911 under the two models. The result approves that the Variance Gamma process is more efficient than the Black-Scholes-Merton model in pricing embedded options. Consequently, the variance gamma process would generate fewer errors in pricing those options that can be used in a practical sense.

روساخت و ژرف ساخت از مباحث علم زبان شناسی هستند. نوآم چامسکی، اولین فردی است که نظریه دستور زایشی - گشتاری را مطرح کرده است. وی از جملات عینی به روساخت و از جملات نهفته در پس آن ها به ژرف ساخت تعبیر می کند. ترجمه لایه های سطحی و توجه به رویکرد صورت مدار در ترجمه، مترجم را از تأمل در لایه های عمیق معنا باز می دارد. در جستار حاضر، نگارندگان بر آن هستند تا از رهگذر رویکرد متن مدارانه، ترجمه های فولادوند، خرمشاهی، مجتبوی و مشکینی را بررسی و هر یک را تجزیه وتحلیل کنند. هدف پژوهش آشنایی بیشتر مترجمان با موضوع ژرف ساخت معنایی به ویژه در متون دینی است تا به وسیله آن مخاطب بتواند ارتباطی بهتر با آن اثر برقرار کند. برآیندهای حاصل از این پژوهش نشان می دهند مترجمان یادشده که ترجمه هایشان ترجمه ای معنایی است، در ترجمه آیات پرکاربرد این کتاب آسمانی، فقط به لایه سطحی معنا توجه داشته باشند و این امر آن ها را از بررسی معنای نهفته عبارت ها بازداشته است.
