Optimal Placement of Electric Vehicle Chargers: A Mixed-Integer Linear Programming Model
No full textElectric vehicle adoption is growing, but New Hampshire lags in public charging infrastructure, especially in rural areas. This gap increases range anxiety and economic inefficiencies. In this study, we developed a mixed-integer linear programming (MILP) model to optimally locate new electric vehicle chargers statewide, maximizing coverage and equity under budget constraints. The model includes geographic coverage requirements, population-weighted equity, capacity limits, and a $28 million budget. Moreover, the model recommends 855 Level 2 chargers and 149 Direct Current Fast Chargers (DCFCs) across 247 ZIP Codes, nearly doubling public charging capacity and achieving 98.8% coverage within defined service radii. The plan offers a cost-effective strategy that balances urban and rural needs. By integrating coverage, equity, and cost considerations, the model provides an adaptable framework for electric vehicle infrastructure planning and demonstrates how operations research supports sustainable transportation policy
Timing and Temperature of Newborn Baths: A Qualitative Improvement Initiative Through Nursing Staff Development
Full text linkAbstract
BACKGROUND: Newborn bathing is a common task performed in a labor and delivery unit of a hospital, a newborn’s bath temperature, timing and how long it is performed, are important metrics to consider. Due to a newborn’s immature thermoregulation, there are multiple implications that come with receiving a bath that is not an optimal temperature or that is too soon after birth. As newborn bathing is often overlooked task due to its quotidian nature, a literature review of current evidence-based practice revealed the urgency to keep the optimal conditions at the forefront of considerations for both nurses and caregivers. This quality improvement project serves to provide renewed nursing knowledge surrounding the topic and highlight these worthwhile efforts.
METHODS: The Plan, Do, Study, Act method was used to implement this initial cycle as a framework for implementing an educational opportunity and gather information on the nurse’s perception surrounding bath temperature education for caregivers. Pre- and post-intervention surveys were integrated in the educational material to gather data on if and how the nurse’s perception changed after exposure to the evidence-based practice included.
INTERVENTION: A ten-slide PowerPoint® presentation was used as nursing reeducation about the optimal conditions of newborn bathing to be demonstrated and taught in the labor and delivery units before discharge. This intervention served to highlight current knowledge about optimal bathing condition for newborns in a hospital’s labor and delivery unit.
RESULTS: Nurses that participated in the educational intervention came to a consensus on the optimal bath temperature of 38ºC. Eleven of the fourteen post-survey participators believed they are likely to include bathwater temperature safety in conversations with caregivers. This shows that with exposure to evidence-based practice such as critical parameters can be reinforced and more likely to be disseminated to caregivers. This leads to better physiological outcomes for infants.
CONCLUSION: Revisiting metrics and methods of daily tasks as a point of reeducating labor and delivery nurses is a worthy cause because it is directly linked to the well-being of infants. Low-cost interventions can have positive outcomes for the growth and development of infants when nurses are primed to share safety information related to newborn care
