The overarching goal of the proposed research is to identify, test, and evaluate technologically enabled and community-supported solutions for temporally distributing travel demand for on-demand public transportation services in an equitable manner, without the use of traditional pricing incentives. We are specifically interested in understanding whether enabling and incentivizing prosocial behavior, such as volunteering to shift one??????????????????s trip time to accommodate others, share a ride, and cooperate with other users to improve outcomes for the user community or to prioritize a transportation disadvantaged user, is a potential solution that is feasible and desirable for communities. If our preliminary analysis during the proposed planning grant (PG) supports the case of cooperative adaptive ride planning, we will investigate how prosocial behavior can be enabled in a trip scheduling environment and be facilitated through the use of artificial intelligence (AI), and we will test and evaluate the efficacy of this approach in improving service during an integrative research grant (IRG). No previous research has explored empathy and prosocial behavior in the context of traveler choices and decision-making.
The purpose of this contract is to deliver training, technical assistance, evaluation, and research evidence in order to support and improve family-centered practice by child welfare workers and their partners. This work will support efforts as described in the North Carolina's Child and Family Services Plan 2020-2024 regarding the Workforce Development (see p. 93-95). The work will support North Carolina's efforts to create a workforce development program, to include training, coaching, leadership development, and skills assessments, that addresses race equity and inclusion and builds the capabilities of the child welfare workforce at state, regional, and county levels to improve outcomes (i.e., Strategic Priority 5, Target 3). Additionally, all work will support actions required under Rylan's Law, including: Strategies to ensure well-trained and adequately compensated staff to improve performance and reduce turnover. Professional development, training, and performance standards. Ensuring a statewide, trauma-informed, culturally competent, family-centered practice framework.
Nina Ferreri will plan and execute human factors activities in support of various User-View, Inc. clients. Activities will include TBD human factors activities that are part of a typical user-centered design process. Example activities include, but are not limited to, task analysis, formative usability testing, contextual inquiry, user interviews, and validation summative usability testing.

The purpose of this project is to develop, execute, summarize the findings of a survey aimed at identifying the perceived advantages and disadvantages of specialized furniture carriers. The survey is to be developed in cooperation with the Specialized Furniture Carriers division of the American Home Furnishings Alliance (AHFA) and an analysis of the results will be documented and reported to this group.
Research on blood glucometers (BG), transfer of training, or usability for older adults (OA) has been conducted in the past. This proposal seeks to integrate these areas, examining the influence of training and age on trial time as well as the number and types of errors committed during a training and transfer task. Hypotheses are that OA will take more time and perform more errors on tasks than younger adults (Y A), and that far transfer errors will be more prevalent than near transfer errors for all participants. The percentage of the population with diabetes has been steadily increasing, especially among OA. Human factors research recommends testing include anticipated users of a product, and has demonstrated significant differences between Y A and OA in numerous studies. One benefit of this proposal is the examination of errors and the ability to transfer information when using 2 current BG. Research will focus on control solution testing (CST), a procedure ensuring a glucometer is obtaining accurate results. Long term benefits of this research include potential aid to designers when constructing future training or products that are portable and require inflexible inputs. A trend toward increased patient self care in medicine has been noted, suggesting a need for research in this area.
