Higher education institutions (HEIs) seek innovative approaches to attract students. Since the COVID-19 pandemic, many HEIs have considered diversification through digitalization. From the initial urgency to implement technology at the start of the pandemic to a gradual acceptance over time, HEIs witnessed a shift in perceptions. This paper aims to explore the evolution of the use of technology in HEI classrooms from pre- to post-Covid-19 as seen through the eyes of students and faculty members.

Seven surveys were conducted from March 2020 to January 2023 with faculty members and students at one business HEI in Switzerland. This longitudinal study analyzed the perceptions of faculty and students regarding technology in the ever-changing HEI environments. These results have been used to make practical recommendations for future HEI classroom settings.

The findings reveal that the social aspect must be considered when implementing technology into HEIs. Faculty members and students need appropriate training and adequate resources to engage with the technology in and outside the classroom. The results suggest that one result of the pandemic was a greater acceptance of blended learning practices in traditional business education.

The pandemic has left long-lasting effects on teaching and learning. While many HEIs revert to traditional ways, the authors suggest the need to embrace technology that encourages engagement and authentic teaching and learning. HEIs must listen to their faculty members and students, to create more innovative learning environments.

Present work deals with the partial substitution of cement by waste demolished concrete powder (WDP) for reducing the carbon footprints of concrete.

Control specimens and the specimens with 20% WDP as fractional substitute of cement were prepared. The waste powder was thermally activated at 825 °C prior to its use in the mix. The prepared specimens were evaluated in terms of density, workability, mechanical strength, Ultrasonic pulse velocity (UPV) and rebound hammer (RH).

The results showed that with the substitution, the workability of the mix increased, while the density decreased. A decrement within a 20% limit was found in compressive strength. The UPV and RH results were closely linked to the other results as mentioned above.

The study deals with only M15 concrete and the substitution level of only 20% as a baseline.

The concrete containing 20% WDP is lightweight and more workable. Moreover, its strength at 28 days is 14 MPa, only 1 MPa lesser than the characteristic strength.

The WDP can be recycled and the dumping in landfills can be reduced. This is an important effort towards the decarbonation of concrete.

Previous literature indicates that the WDP has been frequently used as a partial replacement of aggregates. However, some traces of secondary hydration were also reported. This work considers the effect of partial substitution of cement by the WDP.

Victoria’s Secret, a lingerie retailer founded by Roy Raymond in 1977, is the largest retailer in women’s intimate apparel in North America. Nevertheless, the business has been under fire in the recent past for failing to be inclusive and diverse, declining revenues and engaging in high-profile controversies. Victoria's Secret has experienced competition from emerging lingerie brands including Savage X Fenty, which Rihanna established in 2018, ThirdLove and Aerie by American Eagle & Knix. Victoria's Secret tried to reinvent itself in reaction to these difficulties by altering its marketing approach, switching out its “angels” for more diversified models, and launching a new range of cozy, informal loungewear. However, there were conflicting reactions to these initiatives, and the company's sales have been declining.
