An Example of a Good Dissertation Abstract
Designing an On-Demand Dynamic Crowdshipping Model and Evaluating its Ability to Serve Local Retail Delivery in New York City.
shirin najaf abadiCUNY City College. Nowadays city mobility is challenging, mainly in populated metropolitan areas. Growing commute demands, increase in the number of for-hire vehicles, enormous escalation in several intra-city deliveries and limited infrastructure road capacitiesall contribute to mobility challenges. Decision-makers have to optimize transportation resources to minimize the system externalities especially in large-scale metropolitan areas. This thesis focus on the intra-city mobility problems experienced by travelers in the form of congestion and imbalance taxi resources and businesses in the form of last-mile deliverywhile taking into consideration a measurement of potential adoption by citizens in the form of a survey.
To find solutions for this mobility problem this dissertation proposes three distinct and complementary methodological studies. First, taxi demand is predicted by employing a deep learning approach that leverages Long Short-Term Memory LSTM neural networks, trained over publicly available New York City taxi trip data.
Taxi pickup data are binned based on geospatial and temporal informational tags, which are then clustered using a technique inspired by Principal Component Analysis. The spatiotemporal distribution of the taxi pickup demand is studied within short-term periods for the next hour as well as long-term periods for the next 48 hours within each data cluster.
The performance and robustness of the LSTM model are evaluated through a comparison with Adaptive Boosting Regression and Decision Tree Regression models fitted to the same datasets. On the next study, an On-Demand Dynamic Crowdshipping system is designed to utilize excess transport capacity to serve parcel delivery tasks and passengers collectively.
This method is general and could be expanded and used for all types of public transportation modes depending upon the availability of data. This system is evaluated for the custom dissertation abstracts available study of New York City and to assess the impacts of the crowdshipping system by using taxis as carriers on trip cost, vehicle miles traveled, and people travel behavior, custom dissertation abstracts available.
The survey is analyzed to determine the essential attributes and evaluate the likelihood of individuals participating in the service either as requesters or as carriers. The survey collects information on the preferences and important attributes of New York citizens, describing what segments of the population are willing to participate in a crowdshipping system.
While the transportation problems are complex and approximations had to be done within the studies to achieve progress, custom dissertation abstracts available, custom dissertation abstracts available dissertation provides a comprehensive way to model and understand custom dissertation abstracts available potential impact of efficient utilization of existing resources on transportation systems.
Generally, this study offer insights to decisions makers and academics about potential areas of opportunity and methodologies to optimize the transportation system of densely populated areas. This dissertation offers methods that can optimize taxi distribution based on the demand, optimize costs for retail delivery, while providing additional income for individuals.
It also provides valuable insights for decision makers in terms of collecting population opinion about the service and analyzing the likelihood of participating in the service.
The analysis provides an initial foundation for future modeling and assessment of crowdshipping. najaf abadi, shirin, "Designing an On-Demand Dynamic Crowdshipping Model and Evaluating its Ability to Serve Local Retail Delivery in New York City" CUNY Academic Works.

Many school districts, like New York City, view the principal as the key lever of change in school improvement, particularly in the area of student achievement. There is abundant literature on what principals should be doing but limited research on how principals actually view their own
