The Internet of Things (IoT) refers to the network of devices which contain electronics, sensors or software that enables them to connect at anytimeand anywhere through a cyber-physical system. Before the establishment of such a system, it should be considered to what extent the users are ready to adopt and use it in their daily routines. Therefore, this paper explores users' attitudestowardsusing IoT technologies to receive healthcare services. This is in contrast to most previous research, which has studied the technical requirements or devices of the IoT that are required in healthcare services, or ways in which connectivity and performance can be improved using the IoT. Based on known models of technology acceptance, an integrated framework was developed to investigate the impact of security and privacy concerns, and familiarity with the technology, on users' trust in the IoT, and then to measure the effect of that trust on Omani users' attitudes regarding use ofIoT technologies to receive healthcare services. This framework enabled the measurement of risk perception as a mediator between user trust and their attitudes towards using the IoT. Data were collected from 387 respondents and were analysed using SPSS 25 and AMOS 25 statistics software. Exploratory and confirmatory analysis and structural equation modelling were applied. The findings showed that levels of security, privacy and familiarity affected trustin the IoT. Furthermore, these levels of trust in the IoT were found to affect both users' perceptions of risk in, and their attitude towards, using the IoT. The users' risk perception partially mediated the relations between users' trustand their attitude regarding use of the IoT. The framework was supported and interpreted by 40 per cent of the variance in the attitude towards usingthe IoT in healthcare, while the mediator showed 47 per cent of the variance in the attitude towards using the IoT inhealthcare.

This research aims to identify the factors affecting the adoption of Facebook commerce, in specific the adopted Facebook advertisements for both small and medium enterprises (SMEs) and how this contributes to enhancing such SMEs’ organizational performances. Specifically, ease of use, demographic targeting, interaction, and brand awareness are regarded as the key factors that can influence Facebook’s advertisements adoption. However, three organizational performance dimensions (efficiency, flexibility, and responsiveness) are considered to be the most significant areas of focus in this research. In this study, both the quantitative research approach and the descriptive research design were employed. Data were collected from different SMEs in Muscat and Dhofar in Oman, and the total valid questionnaires suitable for analysis reached 342. The participants were primarily from those who publicize their services through Facebook. Many statistical techniques including exploratory, confirmatory, and structural equation modeling have been adopted in this study; meanwhile, the quantitative data were analyzed using SPSS 25 and AMOS 25 softwares. The findings of this study suggested that the ease of use, demographic targeting, interaction, and brand awareness interpreted 20% of the variance in the Facebook advertisements as the dependent variable. However, Facebook advertisements as an independent variable were found to have a statistically significant effect on the SMEs’ performance dimensions (efficiency, flexibility, and responsiveness) with standard regressions of 0.66, 0.51, and 0.74, respectively, thereby explaining 44% of the variance in the efficiency, 26% of the variance in the flexibility, and 55% of the variance in the responsiveness. Regarding the researchers’ knowledge, this research stands out as the first research to highlight SMEs that measure statistically the relationship between the organizational performance dimensions and Facebook advertising as key social media tools within a unique context—such as Oman as an example of developing countries.

COVID-19 restrictions significantly affected SMEs, which have faced many challenges to their sustainability within this fragile new environment. This study proposes a holistic framework of sustainable performance by interrelating factors showing robust associations to produce this effect' for achieving sustainable performance in SMEs, through integrating the Technology Organisation Environment (TOE) and Resource Based View (RBV) models, to test how sustainable green practices can process the TOE factors when affecting sustainable performance. The research focuses on SMEs with worldwide employees and involves data collected from a range of different employees belonging to four different managerial levels. The process incorporated the analysis of 669 questionnaires to test the proposed hypotheses using structural equation modeling. Findings suggest that, together, TOE factors represent crucial inputs for green practices such as green training, green performance appraisal, that, in turn, mean critical processes lead to sustainable performance (output). Additionally, the findings should also inspire SMEs to focus even more effort on internal technological and organisational factors and to encourage an eco-friendly culture that would demand stakeholders adopt a more positive environmental stance.
