Moor (1985) designated two major problem sources typifying the social and ethical implications of computer technologies, namely, “policy vacuum” and “conceptual muddles.” Motivated by Moor’s seminal definition and Floridi’s (2013) conceptualization of information and communication technologies (ICTs) as re-ontologizing technologies, this study aims to explore Omani undergraduates’ cognition regarding ICT ethics.

Adopting a grounded theory approach for the constant comparative thematic analysis, the constituents of ICT ethics-related cognition among undergraduates and influencing factors were scrutinized. Qualitative data were gathered via focus group discussions with undergraduates and interviews with academics and information systems professionals at Sultan Qaboos University.

In total, 10 thematic categories revolving around a core category, constructing conceptual perceptions of and attitudes toward the realms constituting ICT ethics using an ontological, object-oriented approach, emerged from the comparative analysis. Undergraduates were found to adopt an applied approach when defining professional ICT ethics codes and policies, with a particular focus on information privacy and integrity.

This qualitative study was conducted at a single research site. This may restrict the generalizability of the findings. Postgraduates were not considered when designing this qualitative inquiry.

The findings of the study hold theoretical and methodological significance with regard to ICT ethics-related cognition in the era following the fourth industrial revolution by sustaining feminist ethics in this research. Ultimately, the study developed a substantive theory scrutinizing the constitutive elements of ICT ethics-related cognition among Generation Z.

A research line has emerged that is concerned with investigating human factors in information systems and cyber-security in organizations using various behavioural and socio-cognitive theories. This study aims to explore human and contextual factors influencing cyber security behaviour in organizations while drawing implications for cyber-security in higher education institutions.

A systematic literature review has been implemented. The reviewed studies have revealed various human and contextual factors that influence cyber-security behaviour in organizations, notably higher education institutions.

This review study offers practical implications for constructing and keeping a robust cyber-security organizational culture in higher education institutions for the sustainable development goals of cyber-security training and education.

The value of the current review arises in that it presents a comprehensive account of human factors affecting cyber-security in organizations, a topic that is rarely investigated in previous related literature. Furthermore, the current review sheds light on cyber-security in higher education from the weakest link perspective. Simultaneously, the study contributes to relevant literature by gaining insight into human factors and socio-technological controls related to cyber-security in higher education institutions.

This paper examines associations among the socio-psychological determinants of information and communication technologies (ICT)-assisted deviance-related practices within a group of Omani undergraduates. Moreover, this study aims to evaluate the explanatory burdens of such socio-psychological factors on actual behaviour.

The study implements a predictive research design applied to a cross-sectional sample. At the outset, a theoretical model was built based on the theory of planned behaviour (TPB). Thereafter, structural equation modelling was implemented to test the TPB model on the response data collected from a cluster sample of undergraduates from six universities in the Sultanate of Oman.

The results of the path diagram overwhelmingly support the TPB hypotheses. Specifically, intention is the most influential and immediate predictor of behaviour, while at the same time partially, though markedly, mediating the influence of cognition on behaviour.

This study has implications for the design of inclusive measures of the intrinsic dimensions of ethical self-efficacy as designated by the social cognitive theory of moral thought and conduct, which include moral judgment, self-monitoring of conduct and affective reactions to conduct. As the study reveals the importance of the explanatory power of cognition to explain variance in intention and behaviour, it has implications on the development of ICT-ethics-education.

This study fills a gap in the empirical literature on how intention mediates the relationship between ICT-ethics-connected cognition and behaviour. Moreover, the study addresses the direct relationship between cognition and behaviour – a relationship that is considered equivocal in both theories of planned behaviour and reasoned action.

The purpose of this paper is to present the results of a two-year long study carried out in order to evaluate the corrosion performance of mild steel bare bars (BB) and epoxy-coated rebar (ECR) in concrete under a simulated harsh environment of chlorides.

The blocks are subjected to Southern Exposure testing. The electrochemical impedance spectroscopy (EIS), linear polarization resistance (LPR) and Tafel plot are performed to measure the polarization resistance and corrosion current densities of these rebars. Knife-peel test was performed to assess the adhesion between epoxy and underlying steel after two years of exposure.

Mild steel BB showed a high corrosion current density of 1.24 µA/ cm² in Tafel plots and a very low polarization resistance of 4.5 kΩ cm² in LPR technique, whereas very high charge transfer resistance of 1672 and 1675 kΩ cm² is observed on ECR and ECR with controlled damage (ECRCD), through EIS technique, respectively. EIS is observed to be a suitable tool to detect the defects in epoxy coatings. After two years of immersion in 3.89 percent NaCl⁻ solution, the mild steel BB were severely corroded and a considerable weight loss was observed, whereas under heavy chloride attack, ECR showed no deterioration of epoxy coating and neither any corrosion of underlying steel. Results of this study show that the durability of reinforced concrete (RC) structures with respect to corrosion could be enhanced by using ECR, especially in harsh climatic conditions.

The corrosion performance of mild steel and ECR in concrete under a simulating splash zone environment is evaluated. EIS was used to evaluate the health of epoxy and corrosion state of underneath steel rebars. EIS was able to detect the defects in epoxy. The durability of RC structures could be enhanced in harsh climate regions by using ECR.

Despite the ever-increasing importance of cultivating information, communication and technology literacy skills among college students, they have yet to be related to comprehensive measuring instruments. A glance at the empirical literature reveals that most pertinent scales have been confined to measuring Internet literacy skills, whereas educators in the 21st century advocate an inclusive conceptualization of ICT literacy. Such a comprehensive conceptualization embodies technical, critical, cognitive and emotional competencies. Additionally, more empirical evidence is needed to indicate gaps in testing measurement invariance of ICT literacy scales across genders or cultures. To that end, the current study aims to adapt and cross-validate an ICT literacy self-efficacy scale across gender by testing the measurement invariance using a multiple-sampling confirmatory factor analysis (MCFA). Furthermore, the current study aims to verify the ICT literacy self-efficacy scale's psychometric properties to establish its construct validity and understand the scale's underlying factorial structure.

The current study has administered the scale to a cross-sectional sample of 3560 undergraduate students enrolled in six universities in the Sultanate of Oman.

The results have revealed that the ICT literacy self-efficacy exhibits satisfactory indices of construct validity. On the other hand, the results of MCFA demonstrate that the differences in the goodness of fit indices between the nested models and the baseline model were below the cut-off criterion of 0.01, indicating invariance. Therefore, the scale has proved to be amenable for comparing genders on their ICT literacy self-efficacy using an one-way multivariate analysis of variance.

The study has several implications for research and pedagogical practices. The study provides empirical evidence for establishing ICT literacy self-efficacy as a distinct high-domain construct of task-specific self-efficacy beliefs.

The purpose of this paper is to provide an overview of the development and validation of a self-report structured questionnaire based on the theory of planned behaviour (TPB). The questionnaire was used to investigate university undergraduate students’ cognition, behavioural intent, and behaviour concerning the ethical use of information and communication technologies (ICTs).

A quantitative correlational cross-sectional approach to data collection was used by administering a self-report questionnaire to a sample of 327 undergraduate students. To establish the construct validity of the questionnaire, internal consistency reliability and factorial analyses were performed.

Significant but different correlations between the constructs were under study. The behavioural intention had the greatest and most significant correlation with behaviour pertaining to information ethics. Overall, the scales, which constitute the instrument, showed acceptable indices of measurement validity.

The research implications of this paper shed light on the applicability of the TPB to the specific context in which this study was conducted. The results imply that the TPB framework can be extended and employed to understand better the influence of comprehending information-ethics concepts on the intentions and practices related to the ethical use of ICTs.

The paper has methodological value for researchers who seek to develop empirical instruments for measuring the factors that bear upon the attitudes and the behaviours related to information ethics. Furthermore, the paper has pedagogical value for students, teachers, and developers of information-ethics educational programmes at the tertiary level.

Big Data can be utilised for efficient use of resources and to provide better services to the resident in order to enhance the delivery of urban services and create sustainable build environment. However, the adoption of Big Data faces many challenges at the implementation level. Therefore, the purpose of this paper is to identify the challenges towards the efficient application of Big Data in smart cities development and analyse the inter-relationships.

The 14 Big Data challenges are identified through the literature review and validated with the expert’s feedback. After that the inter-relationships among the identified challenges are developed using an integrated approach of fuzzy Interpretive Structural Modelling (fuzzy-ISM) and fuzzy Decision-Making Trial and Evaluation Laboratory (fuzzy-DEMATEL).

Evaluation of interrelationships among the challenges suggests that diverse population in smart cities and lack of infrastructure are the significant challenges that impede the integration of Big Data in the development of smart cities.

This study will enable practitioners, policy planners involved in smart city projects in tackling the challenges in an optimised manner for the hindrance free and accelerated development of smart cities.

This research is an initial effort to develop an interpretive structural model of Big Data challenges for smart cities development which gives a clearer picture of how the identified challenges interact with each other.

This study aims to investigate the association between vitamin D measured in serum 25 hydroxyvitamin D [25(OH)D] and outcomes of COVID-19 patients in Bahrain. This paper hypothesized that lower serum 25(OH)D concentration in COVID 19 patients is associated with longer viral clearance time (VCT) and higher risk of admission to the intensive care unit (ICU).

This study used a retrospective cohort design of patients admitted to Salmaniya Medical Complex, Manama, Kingdom of Bahrain, from February to June 2020. This study included patients with positive, confirmed COVID-19 diagnosis made using reverse transcription-polymerase chain reaction (RT-PCR), World Health Organization diagnosis manual and local diagnostic guidelines. Primary outcome measures were: VCT measured as the time in days between the first positive RT-PCR test result and the first of two consecutive negative RT-PCR results on recovery and admission need to ICU.

A total of 450 patients were analyzed; mean age was 46.4 ± 12.4 years and 349 (78%) were men. Mean 25(OH)D concentration was 41.7 ± 23.7 nmol/L for the entire sample. Severe vitamin D deficiency (<25 nmol/L) was present in 20%, mild-to-moderate deficiency (25–50 nmol/L) in 55%, insufficiency (50 to <75 nmol/L) in 18% and sufficiency (=75 nmol/L) in 7%. The mean VCT was 12.9 ± 8.2 days. Multivariate linear regression analysis showed that severe vitamin D deficiency was associated with longer VCT, with an average of three extra days after correction for age and sex (β = 3.1; p = 0.001). Multinomial regression analysis showed that vitamin D deficiency was associated with an 83% increased risk of admission to ICU after correction for age and sex (odds ratio = 1.8; p = 0.03).

The results showed that severe vitamin D deficiency was associated with longer recovery time from COVID-19. Low serum 25(OH)D is associated with increased need for critical care in an ICU. Large-scale randomized controlled trials are necessary to further investigate the complex association between vitamin D and COVID-19 infection.
