Cooperation Strategy

Most existing shared automated mobility (SAM) services assume the door-to-door manner, i.e., the pickup and drop-off (PUDO) locations are the places requested by the customers (or demand-side). While some mobility services offer more affordable riding costs in exchange for a little walking effort from customers, their rationales and induced impacts (in terms of mobility and sustainability) from the system perspective are not clear. This study proposes a demand-side cooperative shared automated mobility (DC-SAM) service framework, aiming to fill this knowledge gap and to assess the mobility and sustainability impacts. The optimal ride matching problem is formulated and solved in an online manner through a micro-simulation model, Simulation of Urban Mobility (SUMO). The objective is to maximize the profit (considering both the revenue and cost) of the proposed SAM service, considering the constraints in seat capacities of shared automated vehicles (SAVs) and comfortable walking distance from the perspective of customers. A case study on a portion of a New York City (NYC) network with a pre-defined fleet size demonstrated the efficacy and promise of the proposed system. The results show that the proposed DC-SAM service can not only significantly reduce the SAV’s operating costs in terms of vehicle-miles traveled (VMT), vehicle-hours traveled (VHT), and vehicle energy consumption (VEC) by up to 53, 46 and 51%, respectively, but can also considerably improve the customer service by 30 and 56%, with regard to customer waiting time (CWT) and trip detour factor (TDF), compared to a heuristic service model. In addition, the demand-side cooperation strategy can bring about additional system-wide mobility and sustainability benefits in the range of 4–10%.

It is alleged that the agricultural output in poor countries responds very little to movements in prices and costs because of subsistence-oriented produc¬tion and self-produced inputs. The work of Gupta and Majid is concerned with the empirical verification of the responsiveness of farmers to prices and marketing policies in a backward region. The authors' analysis of the respon¬siveness of farmers to economic incentives is based on two sets of data (concern¬ing sugarcane, cash crop, and paddy, subsistence crop) collected from the district of Deoria in Eastern U.P. (Utter Pradesh) a chronically foodgrain deficit region in northern India. In one set, they have aggregate time-series data at district level and, in the other, they have obtained data from a survey of five villages selected from 170 villages around Padrauna town in Deoria.

Nuanced Understanding

Today’s colleges and universities operate in a complex environment characterized by rapid and unrelenting change, and nowhere do the challenges inherent in change more directly impact students than in the delivery of student services. The need to integrate new models of service delivery, data-driven approaches to enrollment management, greater accountability for student success, stronger emphasis on customer service, and provision of “anytime, anyplace” services through technology are readily evident. Yet, many institutions are finding that their internal cultures are unreceptive, even hostile, toward adopting needed changes. This qualitative case study focusing on a 4- year purposeful change initiative at a community college was conducted to provide higher educational leaders with a more comprehensive and nuanced understanding of the influence of cultural change on student services staff. The results of this study indicated that student services staff constituted a distinct subculture that perceived, experienced, responded to, and influenced planned change differently from other subcultural groups. Specifically, student services staff more demonstrably supported the purpose of the change initiative; identified empowerment, inclusion and involvement in college decision-making, and improved lines of communication as the most important impacts of the change process; and expressed strong confidence regarding the sustainability of the changes that had occurred. Student services staff also indicated that they found greater meaning and developed stronger commitment to their work as a result of the change process. As a result of these findings, implications and strategies that may be helpful in designing and implementing a successful planned change initiative involving student services personnel are presented.

Inclusive Governance

Although New Public Service (NPS) principles are well known, their practice in local government settings has only been limitedly explored. As a means of better understanding governance practices that adhere to NPS principles in local contexts, this study engaged in a case study of Grand Island, New York. Through the analysis of interviews with elected officials and civic servant department heads, it is observed that public servants practice various public engagement strategies for gauging public sentiment and interests in public policy. However, these same public servants point out the challenges of public hearings and social media to understanding their citizens. Information on public servants’ notions of accountability is observed, which relates to how they view the public’s involvement in policy processes. Recommendations for future research are provided as a means of enhancing our understanding and development of more inclusive governance practices.
