Ethics of Technology Practice: Beliefs and Behaviors of Certified Rehabilitation Counselors During the COVID-19 Pandemic

The coronavirus (COVID-19) pandemic represented a critical moment for technology use within rehabilitation counseling. This study explored trends in the beliefs and behaviors of Certified Rehabilitation Counselors (CRCs) regarding the ethical use of technology before and during the pandemic. Specifically, this study compared two groups of CRCs regarding the degree to which they engaged in 59 technology behaviors and whether they viewed each behavior to be ethical. Overall, group comparisons suggested an increased use of telephone, videoconferencing, and email to deliver counseling, assessment, and supervision services during the pandemic. Furthermore, supervision via videoconferencing and email in the pandemic were rated as more ethically appropriate than before the pandemic. As a general trend, synchronous modes of communication such as the telephone and video conferencing were rated as more ethically appropriate than asynchronous modes such as social networking and text messaging. Indicating a high degree of congruence between beliefs and behaviors, the technology practices viewed as most ethical were used the most often. Implications address the revisions to the Code of Professional Ethics for Rehabilitation Counselors regarding the ethical use of technology in rehabilitation counseling.

Simple fabrication of an electrospun polystyrene microfiber filter that meets N95 filtering facepiece respirator filtration and breathability standards.

During the global spread of COVID-19, high demand and limited availability of melt-blown filtration material led to a manufacturing backlog of N95 Filtering Facepiece Respirators (FFRs). This shortfall prompted the search for alternative filter materials that could be quickly mass produced while meeting N95 FFR filtration and breathability performance standards. Here, an unsupported, nonwoven layer of uncharged polystyrene (PS) microfibers was produced via electrospinning that achieves N95 performance standards based on physical parameters (e.g., filter thickness) alone. PS microfibers 3-6 µm in diameter and deposited in an ~5 mm thick filter layer are favorable for use in FFRs, achieving high filtration efficiencies (≥97.5%) and low pressure drops (≤15 mm H2O). The PS microfiber filter demonstrates durability upon disinfection with hydroxyl radicals (•OH), maintaining high filtration efficiencies and low pressure drops over six rounds of disinfection. Additionally, the PS microfibers exhibit antibacterial activity (1-log removal of E. coli) and can be modified readily through integration of silver nanoparticles (AgNPs) during electrospinning to enhance their activity (≥3-log removal at 25 wt% AgNP integration). Because of their tunable performance, potential reusability with disinfection, and antimicrobial properties, these electrospun PS microfibers may represent a suitable, alternative filter material for use in N95 FFRs.
