    Climate change and business accountability, empirical evidence on the roles of environmental strategy and environmental accounting.Mohammed S. Y. Omran & Mohammad N. S. Yaaqbeh - 2023 - Business Ethics, the Environment and Responsibility 32 (4):1592-1608.
    This study examines the roles of environmental strategy and accounting in corporate carbon performance, as measured by the Greenhouse Gas (GHG) Protocol. A novel interaction model is developed based on legitimacy theory and natural-resource dependence theory to capture the interaction between environmental strategy and accounting. An international sample of 3322 firms from 73 countries is used in the analysis, based on a panel data design for 17 years (2005–2022). The empirical findings reveal an overall reactive role of these environmental initiatives (...)

    Corporate Legitimacy and Investment–Cash Flow Sensitivity.Omrane Guedhami, Sadok El Ghoul, Sean W. Cleary & Najah Attig - 2014 - Journal of Business Ethics 121 (2):297-314.
    This study provides novel evidence of the impact of corporate social responsibility (CSR) on investment sensitivity to cash flows. We posit that CSR affects investment–cash flow sensitivity (ICFS) through information asymmetry and agency costs, commonly viewed as the two channels through which investment responds to the availability of internal cash flows. We find that CSR performance leads to a decrease in ICFS. We further find that ICFS decreases (increases) when CSR strengths (concerns) increase. Finally, we find that the effect of (...)

    Applying Deep Learning Methods on Time-Series Data for Forecasting COVID-19 in Egypt, Kuwait, and Saudi Arabia.Nahla F. Omran, Sara F. Abd-el Ghany, Hager Saleh, Abdelmgeid A. Ali, Abdu Gumaei & Mabrook Al-Rakhami - 2021 - Complexity 2021:1-13.
    The novel coronavirus disease is regarded as one of the most imminent disease outbreaks which threaten public health on various levels worldwide. Because of the unpredictable outbreak nature and the virus’s pandemic intensity, people are experiencing depression, anxiety, and other strain reactions. The response to prevent and control the new coronavirus pneumonia has reached a crucial point. Therefore, it is essential—for safety and prevention purposes—to promptly predict and forecast the virus outbreak in the course of this troublesome time to have (...)

    Breast Cancer Identification from Patients’ Tweet Streaming Using Machine Learning Solution on Spark.Nahla F. Omran, Sara F. Abd-el Ghany, Hager Saleh & Ayman Nabil - 2021 - Complexity 2021:1-12.
    Twitter integrates with streaming data technologies and machine learning to add new value to healthcare. This paper presented a real-time system to predict breast cancer based on streaming patient’s health data from Twitter. The proposed system consists of two major components: developing an offline building model and an online prediction pipeline. For the first component, we made a correlation between the features to determine the correlation between features and reduce the number of features from the Breast Cancer Wisconsin Diagnostic dataset.

    Shareholders versus stakeholders: Corporate mission statements and investor returns.Mohammed Omran, Peter Atrill & John Pointon - 2002 - Business Ethics, the Environment and Responsibility 11 (4):318–326.
    This paper seeks to discover whether companies that adopt a stakeholder approach, and thereby demonstrate a wider remit of corporate responsibility, provide inferior returns to those that embrace the shareholder value approach. To classify approaches, mission statements were analysed, the final sample comprising 32 shareholder oriented companies and 48 stakeholder oriented companies. To assess performance both accounting–based and market–based measures were used. A number of moderating variables were taken into account: systematic (beta) risk, gearing (long–term debt to total long–term finance), (...)

    Adaptive intelligent learning approach based on visual anti-spam email model for multi-natural language.Akbal Omran Salman, Dheyaa Ahmed Ibrahim & Mazin Abed Mohammed - 2021 - Journal of Intelligent Systems 30 (1):774-792.
    Spam electronic mails (emails) refer to harmful and unwanted commercial emails sent to corporate bodies or individuals to cause harm. Even though such mails are often used for advertising services and products, they sometimes contain links to malware or phishing hosting websites through which private information can be stolen. This study shows how the adaptive intelligent learning approach, based on the visual anti-spam model for multi-natural language, can be used to detect abnormal situations effectively. The application of this approach is (...)

    Does Religion Matter to Equity Pricing?Sadok El Ghoul, Omrane Guedhami, Yang Ni, Jeffrey Pittman & Samir Saadi - 2012 - Journal of Business Ethics 111 (4):491-518.
    For a sample comprising 36,105 U.S. firm-year observations from 1985 to 2008, we find that firms located in more religious counties enjoy cheaper equity financing costs. This result is robust to a battery of sensitivity tests, including alternative assumptions and model specifications, additional controls for noise in analyst forecasts, and various approaches to addressing endogeneity. In another set of tests, we find that the equity pricing role that religion plays comes predominantly from Mainline Protestants. We also document that the effect (...)

    Corporate Environmental Responsibility and the Cost of Capital: International Evidence.Sadok El Ghoul, Omrane Guedhami, Hakkon Kim & Kwangwoo Park - 2018 - Journal of Business Ethics 149 (2):335-361.
    We examine how corporate environmental responsibility affects the cost of equity capital for manufacturing firms in 30 countries. Using several approaches to estimate firms’ ex ante equity financing costs, we find in regressions that control for firm-level characteristics as well as industry, year, and country effects that the cost of equity capital is lower when firms have higher CER. This finding is robust to addressing endogeneity through instrumental variables, to using alternative specifications and proxies for the cost of equity capital, (...)

    An improved Jaya optimization algorithm with ring topology and population size reduction.Giovanni Iacca & Mahamed G. H. Omran - 2022 - Journal of Intelligent Systems 31 (1):1178-1210.
    An improved variant of the Jaya optimization algorithm, called Jaya2, is proposed to enhance the performance of the original Jaya sacrificing its algorithmic design. The proposed approach arranges the solutions in a ring topology to reduce the likelihood of premature convergence. In addition, the population size reduction is used to automatically adjust the population size during the optimization process. Moreover, the translation dependency problem of the original Jaya is discussed, and an alternative solution update operation is proposed. To test Jaya2, (...)

    Collectivism and Corruption in Commercial Loan Production: How to Break the Curse?Sadok El Ghoul, Omrane Guedhami, Chuck C. Y. Kwok & Xiaolan Zheng - 2016 - Journal of Business Ethics 139 (2):225-250.
    Recent research suggests that collectivism breeds corruption in bank lending. This finding, together with the stickiness of culture, poses a direct challenge to economic growth in collectivist societies. In this paper, we address this grim outlook by examining the types of firms that are susceptible to the detrimental effect of collectivism on lending integrity and the formal institutions that can help alleviate such effect. We find that the adverse effect of collectivism on bank corruption is more severe in small and (...)

    New Evidence on the Role of the Media in Corporate Social Responsibility.Ajay Patel, Robert Nash, Omrane Guedhami & Sadok El Ghoul - 2019 - Journal of Business Ethics 154 (4):1051-1079.
    Prior research suggests that the media plays an important information intermediary role in capital markets. We investigate the role of the media in influencing firms’ engagement in corporate social responsibility activities. Using a large sample of 4396 unique firms from 42 countries over the period 2003–2012, we find strong evidence that firms engage in more CSR activities if located in countries where the media has more freedom. This relation is robust to using various proxies for media freedom, an alternative source (...)

    Foreign Institutional Investors, Legal Origin, and Corporate Greenhouse Gas Emissions Disclosure.Simon Döring, Wolfgang Drobetz, Sadok El Ghoul, Omrane Guedhami & Henning Schröder - 2023 - Journal of Business Ethics 182 (4):903-932.
    The disclosure of corporate environmental performance is an increasingly important element of a firm’s ethical behavior. We analyze how the legal origin of foreign institutional investors affects a firm’s voluntary greenhouse gas emissions disclosure. Using a large sample of firms from 36 countries, we show that foreign institutional ownership from civil law countries improves the scope and quality of a firm’s greenhouse gas emissions reporting. This relation is robust to addressing endogeneity and selection biases. The effect is more pronounced in (...)

    Firm Internationalization and Corporate Social Responsibility.Najah Attig, Narjess Boubakri, Sadok El Ghoul & Omrane Guedhami - 2016 - Journal of Business Ethics 134 (2):171-197.
    Using a large sample of 3,040 U.S. firms and 16,606 firm-year observations over the 1991–2010 period, we find strong evidence that firm internationalization is positively related to the firm’s corporate social responsibility rating. This finding persists when we use alternative estimation methods, samples, and proxies for internationalization and when we address endogeneity concerns. We also provide evidence that the positive relation between internationalization and CSR rating holds for a large sample of firms from 44 countries. Finally, we offer novel evidence (...)

    Corporate Social Responsibility and Credit Ratings.Najah Attig, Sadok El Ghoul, Omrane Guedhami & Jungwon Suh - 2013 - Journal of Business Ethics 117 (4):679-694.
    This study provides evidence on the relationship between corporate social responsibility and firms’ credit ratings. We find that credit rating agencies tend to award relatively high ratings to firms with good social performance. This pattern is robust to controlling for key firm characteristics as well as endogeneity between CSR and credit ratings. We also find that CSR strengths and concerns influence credit ratings and that the individual components of CSR that relate to primary stakeholder management matter most in explaining firms’ (...)

    The relationship between environmentally induced emotion and memory for a naturalistic virtual experience.Aria S. Petrucci, Cade McCall, Guy Schofield, Victoria Wardell, Omran K. Safi & Daniela J. Palombo - forthcoming - Cognition and Emotion.
    Emotional stimuli (e.g. words, images) are often remembered better than neutral stimuli. However, little is known about how memory is affected by an environmentally induced emotional state (without any overtly emotional occurrences) – the focus of this study. Participants were randomly assigned to discovery (n = 305) and replication (n = 306) subsamples and viewed a desktop virtual environment before rating their emotions and completing objective (i.e. item, temporal-order, duration) and subjective (e.g. vividness, sensory detail, coherence) memory measures. In both (...)

    Ethical Issues in Photovoice Studies involving Key Populations: A Scoping Review.Chong Guan Ng, Sing Qin Ting, Rumana Akhter Saifi & Adeeba Bt Kamarulzaman - 2023 - Asian Bioethics Review 16 (1):109-129.
    Photovoice, a community-based participatory research method, employs images and words to convey participants' needs, concerns, and desires. It proves particularly valuable in researching marginalized communities who face elevated health risks, disease transmission, and social and health disparities. This paper seeks to investigate the ethical considerations inherent in photovoice research projects. We conducted an extensive literature review spanning four databases to identify pertinent photovoice studies. Ethical issues from the selected articles were identified, categorized, and summarized. Our analysis of twenty-five photovoice studies (...)
