Acrylamide (AA) is predominantly used as a synthetic substance within various industries. However, AA is also recognized as a carcinogen. Zinc oxide nanoparticles (ZnO-NPs) are becoming increasingly attractive as medical agents. However, to the knowledge, the effects of ZnO-NPs on preventing cytotoxicity with AA have not been reported. Therefore, this study aims to determine the protective effects of ZnO-NPs against the cytotoxicity caused by AA.

MTT assay was used to determine the cytotoxicity. Reactive oxygen species (ROS) formation, carbonyl protein, malondialdehyde (MDA) and glutathione (GSH) were measured and analyzed statistically.

The findings observed that the presence of 200 µM AA led to a substantial reduction in cell viability (p < 0.001). However, ZnO-NPs restored cell viability at 50 and 100 µM concentrations (p = 0.0121 and p = 0.0011, respectively). The levels of ROS were significantly reduced (p = 0.001 and p = < 0.001) to 518 ± 47.57 and 364 ± 47.79, respectively, compared to the AA group. The levels of GSH were significantly increased (p = 0.004 and p = 0.002) to 16.9 ± 1.3 and 17.6 ± 0.5, respectively, compared to the AA group. The levels of MDA were significantly decreased (p = 0.005, p < 0.001 and p < 0.001) when compared to the AA group, as were the levels of carbonyl protein (p = 0.009 and p < 0.002) in comparison to the AA group.

In summary, the outcomes of this research indicate that ZnO-NPs played a role in inhibiting AA-induced oxidative stress and cytotoxicity.

This paper aims to investigate corporate social responsibility (CSR) practices in Iran from the perspective of employees.

To achieve the objectives of this research, the perceptions of 142 Iranian employees were examined regarding the CSR practices of their respective organizations. The required data were collected using a questionnaire. Exploratory factor analysis was conducted to refine scale items and confirm the factorial structure of the scale applied. Descriptive statistics and a t‐test were used to analyze the data.

The paper unveils information about the current status of CSR in Iran from the perspective of employees, and shows that on average Iranian employees perceive their organizations to be committed to CSR, although the mean CSR scores were relatively low in all dimensions. Also, this research shows that while the four‐factorial structure of Truker's CSR scale was confirmed in the Iranian context, some of the items had to be removed from the original scale when measuring CSR.

The relatively low mean on the categories of CSR among Iranian organizations from the perspective of employees indicates the infancy level of CSR among Iranian organizations and calls for further awareness among Iranian organizations and managers about the issue of CSR. This research also shows that researchers need to be cautious when using CSR scales that have been developed in Western or European contexts to measure social responsibility activities of organizations in culturally different contexts such as the Middle East. A major limitation of this research pertains to sample size, which limits the generalizability of the findings to the whole country.

This research indicates the infancy level of CSR among Iranian organizations and calls for further engagement of Iranian organizations in social initiatives and community outreach endeavors.

Being among the first research studies of its kind to examine the CSR status in Iran, this study provides invaluable understanding and insights about the status of CSR in Iran, an important country in the Middle East. Furthermore, it validates and supports a recently proposed CSR scale by providing empirical findings from a culturally different context.

Applying digital literacy skills in face-to-face or online classrooms started ringing the changes during the COVID-19 pandemic in recent months. Stating the obvious, well-planned distant learning experiences are different from courses offered online in response to a crisis or disaster. Every institution around the world has worked on preserving instruction throughout the COVID-19 pandemic. The extent to which educators being aware of their own and their students’ digital literacy skills perceived how and what kind of information and communication technologies are used under such an emergency remote teaching and learning. The preparedness level of learners in using online information and communication technologies is a naturally regulated phenomenon because they are born to live a life of technology. Yet, educators have applied experience, and practical knowledge in face-to-face classroom settings remains a mere curiosity to remote teaching. This study was conducted to investigate educators’ level of preparedness to use online information and communication technologies for their emergency remote teachings and their experiences from the field by focusing on moderating variables – asserted by Means, Bakia, and Murphy (2014) – like modality, instructor role online, online communication synchrony, source of feedback, and role of online assessments. Based on self-report scaled and open-ended questions in the same questionnaire, the participants were recruited online via convenience and accidental sampling, and the data were analyzed by using Statistical Package for Social Sciences software version 22.0 and thematic analysis. Within this study, how educators experience remote teaching during the global pandemic and what they prefer to carry out for the same effectiveness of the courses are discussed based on their digital literacy skills and digital readiness.

Current policies and research on carbon emissions focus on operational emission but overlook the importance of embodied and user-transport emissions in residential buildings. This study built a comprehensive framework to assess the impact of life-cycle carbon emissions on different in-building open public spaces (open roof, open vertical garden, and open ground floor) in affordable housing.

A parametric model of a typical affordable housing building in Shanghai, China was constructed and 36 variations of open public spaces studied. Embodied, operational, and user-transport carbon emissions were quantified over 50 years.

The results show that the life-cycle carbon emissions decrease with the application of the open public space. In addition, the paper found that the carbon reduction due to user transport is seven times higher than the carbon increment due to construction and over long-term operation.

This paper provides quantitative evidence for carbon emissions and in-building open public spaces, and the authors suggest taking multiple aspects into account in addition to the structure of the building is crucial to sustainable building development.
