COVID-19 lockdowns led to increased adoption of online teaching with courses that have an asynchronous format. It is recognized that some students could be online without dedicating all oftheir time to the class. This study aims to investigate whether there exists any association between the hours students invest in online classes with the point scores they achieve. Data on semester participation hours and total point scores were gathered in CNST 440-540, an asynchronous onlineclass at Eastern Michigan University from the winter semester of 2016 to the winter semester of 2021. Statistical modeling revealed a modest but significant relationship between student onlinetime and actual point scores.

Incorporating industrial robots into current robotics curricula has become a key component for engineering and technology programs. Recently, Toyota Motor Engineering & Manufacturing North America donated a Kawasaki ZB150S industrial robot to the Engineering Technology Programs at Northern Kentucky University. The entire Kawasaki industrial robot system was installed in a safeguard cage; however, the safeguard cage was not always able to prevent unauthorized students from coming into the working area of the robot. The lab manager/staff expressed an urgent need for a smart tool that could monitor occurrences of unauthorized operating conditions to help them improve laboratory safety. Thus, a Global System for Mobile (GSM)-based intelligent monitoring system has been designed and developed to provide a safe robotics lab operating environment for students. This intelligent monitoring system was divided into two subsystems: one was the Embedded Laboratory Environmental Monitoring and Robot Power Control (ELEMRPC) subsystem; the other was the GSM communication subsystem. The ELEMRPC subsystem received the presence-sensing signals from the light curtains at the cage entrance and disarmed the power supply of the robot when unauthorized students were detected. Additionally, the lab environmental parameters were monitored. The GSM subsystem wirelessly transmitted text messages (e.g., lab safety information) to designated cellular phones. These text notifications can alert lab manager/staff immediately to prevent potential accidents within the footprint of the robot safety cage. This paper discusses in greater detail the design, development, and hardware implementation of the robotics laboratory safety monitoring system.

The focus of this research was to improve the device structure and electrode geometry of nanophotodiode array (NPDA) subretinal implant devices for retinal implants, with the aim to restore the sight of people who have lost their vision and visual acuity (VA) to better than blindness level. In light of the electronic device simulator, the authors present a design depicting the configuration of a high-efficiency NPDA device by incorporating organic nanomaterials. The present researchers’ simulated NPDA device embeds 3600 stimulating pixels (100 μm in diameter) dispersed over a 5.5-mm active radius area. By optimizing the NPDA device geometry, authors demonstrated that each pixel has the potential to produce the required electrical current and voltage for neuronal stimulation utilizing an irradiance of 12 mW/mm2. Here, the authors concentrated on increasing the efficiency of the device because the increase in efficiency will tend to result in more pixels (greater number of electrodes by reducing the electrode geometry) if the increase in a pixel increases the visual perception. Therefore, theoretically, the 100-μm Tin electrode can reinstate VA up to 20/80.This NPDA implant has the potential to reinforce vision to a level of VA that is superior to that of the vision loss level.

The Indy Autonomous Challenge (IAC) was a competition among universities from around the world created to showcase fully autonomous operations under the extreme circumstances encountered in high-performance racing. The pinnacle of the virtual portion of the competition occurred on June 30,2021, during the IAC Simulation Race that consisted of a series of qualifying events followed by a head-to-head race. The objectives of this paper are to present a team’s controller and demonstrate its performance throughout the IAC until the final simulation race. The results presented in this paper were obtained by testing the team’s controller within a simulated environment. The final controller is capable of sustaining speeds of nearly 300 kph (186 mph) with an average speed of 280 kph(174 mph) and a maximum speed of 298 kph (185 mph). The final steering proportional-integral-derivative controller yielded cross-track errors no more than 4.7 meters from the desired waypoint. Analysis of the simulated vehicle’s G-G diagram reveals that the vehicle could sustain operations while experiencing over 2.5 Gs of lateral force as it navigated the turns of the track, and there is evidence to suggest that future work can be performed to tap into the full potential of the tires’ grip capabilities.The results presented in this report are indicative that the race team’s controller can perform safe high-speed operations in the presence of seven additional script-controlled opponents within a simulated environment.

Changes in the economy and decreases in enrollment have changed the landscape of higher education and caused a shift in the demographics of the students who are currently enrolled. Colleges are no longer recruiting or enrolling the traditional student; instead, it is nontraditional and underrepresented students who are seeking new skills that degrees or certificates can provide. Stackable degrees can provide a solution or alternative to assist colleges and students within this changing landscape. Stackable degrees are credentials that recognize achievement on a smaller scale. These degrees provide students and universities a win-win opportunity by increasing program enrollment and credentials awarded to students. This article will explore one university’s approach to offering stackable credentials. Researchers conducted a meta-analysis comparison study of stackable programs and traditional programs available. Results showed that buildable programs had a significant impact on enrollment for nontraditional students as well as the number of credentials awarded.

Accreditation standards and criteria motivate much of the efforts to continuously improve public higher education institutions in the United States. A key mechanism in this accreditation process for many agencies is an onsite physical visitation of the institution and/or program by an accreditation visiting team. This visit can provide tangible information, observation, and characterization of the institution or program under review, which informs a final accreditation decision. Due to the 2019 coronavirus disease (COVID-19) pandemic and the ensuing travel and physical distancing protocols, many accrediting agencies were required to hold traditional onsite visits virtually during the spring of 2020.Not only was this an ad hoc transition, but it was also made without full knowledge of the impact that the shift in evaluation mode would have on the effectiveness and quality of accreditation reviews against accreditation standards and criteria. Therefore, a critical need exists to evaluate the efficacy of the virtual mode of accreditation review. This study analyzed the impacts of virtual site visits on accreditation review effectiveness and quality. Using survey data collected from the Association of Technology, Management, and Applied Engineering (ATMAE)’s Board of Accreditation, from visiting team members, and from institutional contacts involved in the 2020 accreditation visits, an assessment of the effectiveness and quality of accreditation reviews was performed. Qualitatively, strong themes were found in the data set revealing the impacts of the virtual modality on accreditation review effectiveness and quality; advantages, disadvantages, and opportunities to leverage the remote modality were also discovered and are highlighted. Quantitatively, the virtual modality was overwhelmingly reported to be effective for most accreditation standards, whereas impacts on quality were more negligible. The results of this study help characterize the impacts on accreditation amid the COVID-19 pandemic, provide a picture of lessons learned from the use of this modality, and begin to lay a preliminary foundation for best practices for future virtual accreditation site visits.

Recognizing the importance of ethics in industry today, the relevant strategy literature offers several anecdotal and prescriptive narratives to strengthen certain ethical concepts. The National Business Ethics Survey (NBES) shows that employees have lost faith in management’s ethics. Industry has anethical crisis of massive proportion, and because of this, companies like Enron toppled, taking both thelivelihood and life savings of their employees. Corporate culture is engulfed with greed with noreasonable check and balance. Currently, ethical rules and standards appear to be a “management only” club. To change this aspect in the industry will require the education of employees. As employees are promoted or are required to make ethical decisions, the basis of the decisions will come from ethics; therefore, ethical training is required. Companies avoid ethics training because of concerns that ethically trained employees will undoubtedly raise questions about specific company policies and actions.

A primary motivation for using Open Educational Resources (OERs) is to increase access by reducing students’ financial burden. While this was a motivating factor in this study, the authors also were interested in understanding OER’s impact on student learning. Therefore, this study describes the adaption process for an OER textbook used in a junior-level undergraduate electricity course and evaluates this OER’s effectiveness to increase student access and improve learning over the baseline textbook. A quasi-experimental, non-equivalent design collected exam scores, and self-reported survey responses from n=144 students in a comparison (non-adapted OER; n=83) and treatment (adapted OER; n=61) group was used. Based on Student’s t, Kolmogorov Smirnov, and Chi-square (?2) tests, the adapted OER was effective at improving access and learning while also saving enrolled students an average of $8,000 per year, collectively. A brief background of OER databases, materials, and methods used to develop the OER and the intellectual contribution of the newly adapted OER, and lessons learned are included in the study.
