One of the most significant current discussions in the understanding of the human brain is the functional recruitment of some regions of the cortex for specific tasks, regardless of the sensory modality (e.g. visual, tactile or auditory) in which the stimuli is received. The ability to perceive motion, among other visual properties, is a fundamental faculty of the human brain. Brain lesions that impair the detection and processing of motion have a profound impact on daily activity. Consequently, visual motion processing is one of the most fundamental and well-studied systems in the human brain, canonically known to develop mainly for the purpose of visual perception. A great deal of study on the multisensory responses to motion processing in the human brain focused on the middle temporal complex and superior temporal sulcus. Several studies using both neurophysiological and neuroimaging techniques showed the multisensory properties of these areas, showing their recruitment during both tactile and auditory motion stimulation. Despite the large amount of study on the topic it is still unclear whether the recruitment of these areas directly mediates the perception of motion through the different sensory input or regulates responses within primary sensory areas involved in the task. This MSCA fellowship allowed me to lay the foundations on the neural substrate underlying multisensory motion perception. We discovered that hMT+, an area mainly involved in visual motion processing, encode motion via spatial features of the stimulation rather than its intrinsic speed and our preliminary results show that, together with other visual areas, is able to decode speed via auditory and tactile motion stimulation, proving its multisensory function.

Strengthening Data Protection: Ensuring Privacy and Security for Nigerian Citizens
This Policy Brief examines the existing data protection regime both in Nigeria and globally and suggests ways to improve the data protection efforts in Nigeria. It considers Nigeria’s principal data protection laws, generally applicable across all sectors (including public and private institutions). By examining and juxtaposing some of the exemptions in legislation, an opportunity for abuse of data subjects’ rights may have been inadvertently created by laws that were enacted to do otherwise. This Policy Brief proffers preferable outcomes that may guide engagement with policymakers to rectify this situation.

Do They Really Care about Us? On the Limits of State Intervention
This paper examines the limits of state intervention through the relationship between freedom and equality, the rule of law and social justice, as well as through two highly contradictory concepts regarding the scope of government action – the concepts of minimal state and paternalistic state. Accordingly, we seek to identify a model capable of outlining the extent to which the state can intervene in the light of socially beneficial goals, but without compromising individual freedom. Since we cannot find such a model within the extreme positions of liberalism and socialism, this paper seeks to offer a satisfactory solution by mitigating some of the ideologically exclusive positions. It embraces Aristotle’s teaching about the middle as a virtue and proposes sophisticated neoliberalism as a potential alternative to the status quo. Still, as insisted, the government should never be allowed to assume uncontrollable powers and create conditions for collectivist doctrines that recognize no individual freedom.

Artificial intelligence practices in everyday news production: The case of South Africa’s mainstream newsrooms
This article explores artificial intelligence (AI) uptake in selected South African mainstream newsrooms. It seeks to determine the extent to which AI has been adopted and how journalists and editors perceive its appropriation in newsmaking practices. To address these two broad aims, the study used in-depth interviews with journalists and editors. Our findings suggest a slow, varied but methodical uptake of AI practices in South Africa’s mainstream newsrooms. We deduced three uses of AI in these newsrooms. The first is what we call the holistic appropriation of AI. The second one is the exclusively technological appropriation of AI, and the last one is the task-specific appropriation of AI. This varied uptake of AI is taking place against a deep-seated skepticism with this technology.

Board 164: Engineering Interventions in My Science Classroom: What’s My Role?
This work in progress paper draws on data from year one of a multi-year project aimed at integrating engineering into middle-school science classes. The expectation that middle school teachers integrate engineering into their science curriculum may be challenging as engineering related content has not historically been part of teacher preparation. Particularly in rural areas, in service teacher training related to engineering may be absent or difficult to access due to proximity or financial or time costs. Therefore, it is important to develop effective professional development (PD) that works within the actual teaching context and makes few demands on teachers beyond their regular workload. In partnership with teachers and local industry workers in rural and Appalachian areas, the Virginia Tech Partnering with Educators and Engineers in Rural Schools (VT-PEERS) project developed extended classroom engineering activities for students that also served as teacher PD related to teaching engineering in locally relevant ways. As part of this work, a qualitative analysis was conducted to understand how teachers, from their perspectives, envisioned their role during the interventions. Data were collected prior to and after interventions (within an academic year) to further understand if, and if so, how, teacher perspectives of their role changed. Results reveal three initial roles; classroom manager, learner, helper, and unsure. The post intervention data revealed all teachers indicated being a “learner”.

Board 192: Identifying and addressing the barriers to advancement for women in the engineering professoriate: A systematic review of literature
This work-in-progress paper shares ongoing findings from a mixed-methods systematic literature review that seeks to examine the retention of women in the engineering professoriate. We identified literature from EBSCOHost and Engineering Village that discussed women in the engineering professoriate in relation to either retention or persistence or both, as explicitly stated in their abstract. Following an initial review of 191 titles, 48 papers passed our inclusion criteria; further qualitative analysis of abstracts yielded 31 papers, which underwent a full paper review. Our ongoing findings suggest the following: a) research on the retention of women in engineering professoriate is being supported by grants and funding opportunities; b) the reviewed literature documented six barriers faced by women in the engineering professoriate: isolation of women faculty, work/life balance, inequitable distribution of service, underrepresentation of women faculty, implicit bias, and departmental resources; and c) although journal scholarship on this topic is not limited to popular engineering education publishing venues, conference scholarship are mainly from those popular in the field, such as the ASEE Annual Conference and the Frontiers in Education Conference. Future work will share the extent to which the reviewed literature discussed interventions to recruit or retain women in the engineering professoriate, and whether these interventions vary by the type of institution.

Does “Fortress Europe” have an alternative? EU member states between solidarity and national interests
This paper examines the repercussions of the 2015 European migrant/refugee crisis, which culminated with the 2018 dispute between Italy and France. It is concerned with the Dublin Regulation and the New Pact on Asylum and Migration, which are critical to the division and consequent polarizations across the EU. The Member States’ failure to show solidarity and agree to share the burden in relation to the distribution of immigrants and asylum seekers has brought the European integrationist project into question. In addition to considering the general theoretical explanations, the paper also looks into the African-origin migration/displacement as a proper trigger of widespread disagreements among European governments. The deliberate and systematic impoverishment of the local inhabitants – largely through the use of the French Treasurytied Communauté Financière Africaine (CFA) franc – exposes the neo-colonial nature of the current practices and thus jeopardizes all those discourses and policy initiatives focused on the provision of peace and stability.

Health chatbots in Africa: scoping review
Background
This scoping review explores and summarizes the existing literature on the use of chatbots to support and promote health in Africa.Objective
The primary aim was to learn where, and under what circumstances, chatbots have been used effectively for health in Africa; how chatbots have been developed to the best effect; and how they have been evaluated by looking at literature published between 2017 and 2022. A secondary aim was to identify potential lessons and best practices for others chatbots. The review also aimed to highlight directions for future research on the use of chatbots for health in Africa.Methods
Using the 2005 Arksey and O’Malley framework, we used a Boolean search to broadly search literature published between January 2017 and July 2022. Literature between June 2021 and July 2022 was identified using Google Scholar, EBSCO information services—which includes the African HealthLine, PubMed, MEDLINE, PsycInfo, Cochrane, Embase, Scopus, and Web of Science databases—and other internet sources (including gray literature). The inclusion criteria were literature about health chatbots in Africa published in journals, conference papers, opinion, or white papers.Results
In all, 212 records were screened, and 12 articles met the inclusion criteria. Results were analyzed according to the themes they covered. The themes identified included the purpose of the chatbot as either providing an educational or information-sharing service or providing a counselling service. Accessibility as a result of either technical restrictions or language … -
Preparing engineering students to find the best job fit: Starting early with the career development process
In spite of the vast amount of literature that focuses on the need for significantly more science, technology, engineering, and mathematics (STEM) graduates, the importance of a student finding a good career fit, and what makes a student employable, little research exists on undergraduate engineering students’ understanding of the process of how to find, qualify for, and secure a preferred first position after graduation (FPAG). Likewise, it is important for research to consider nuanced distinctions within STEM fields to assist research to practice transitions. Competition in securing jobs upon graduation is expected to continue, including for engineering positions. In fact, even in a market of high demand for STEM graduates, employers need candidates that display the skills, interests, and readiness to be successful employees.

Excellence, Belonging, and the American Dream: An Auto-ethnography on Being International in Engineering
This research paper uses an auto-ethnographic approach to highlight experiences of women of color who are international in U.S. engineering workforce and classrooms. Three preliminary themes are highlighted in this paper. The first is the theme related to the notion of Excellence, and how the definitions of success for immigrating or international engineers may be tied to maintaining visa status. The second theme centers around the lack of Sense of Belonging expressed by participant-authors. The final theme was around Chasing the American Dream and the resultant sacrifices. We hope this paper not only provides an overview of some of the unique challenges faced by international women of color, but also drives more interest in better understanding this oft-overlooked group in engineering.
