Investigating the Impact of Financial Aid on Four-year College Enrollment among College-Qualified Students

Over the past decades, policymakers have developed numerous financial aid policies and programs with the goal of promoting college access and equity. However, access to American higher education is unduly limited by the complex interplay of inadequate preparation, lack of information about college opportunities, and persistent financial barriers (The U.S. Department of Education, 2006). Using Hossler and Gallagher’s (1987) three phase college choice model as a framework, this study analysis the restricted use data from the National Education Longitudinal Study (NELS:88/2000) to investigate how financial aid influence four year college enrollment among academically qualified students. This study also examined if this relationship varied across students with different social background. The findings demonstrate that low income and middle-income college-qualified students tend to respond more to loans and work-study. The study findings have important implications for financial aid policy as well as future research on the role of financial aid policy in college choice of academically qualified students from different income backgrounds

Power flow in railway electrification power system

This thesis discusses aspects of the design of the railway electrification system (RES) and in particular the electric distribution system for a 2x25 kV railway power system. The analysis of Railway Power Supplies (RPS) presents a unique type of load flow problem which is characterized by its constant moving loads, dynamically changing load types (constant current/constant power), and its specialized network structure. The autotransformer power supply system with double track was the system studied in this thesis. The details of the system studied were provided by Caltrain (California Commuter Rail) for a planned high speed extension to Caltrain system. A more accurate electrical model of such a system than currently available is used. The thesis investigates the use of SimPower toolbox provided by MATLAB/SIMULINK to model and solves the load flow problem in the system under study. It was found that the RES could be modeled and solved successfully using SimPower. Further, the study paves the way for fault analysis of such a system using SimPower

Effectively Settling SMEs financing Difficulty with Warehouse Receipt-a Case from China

SMEs financing is a difficult problem in the world, and it is more difficult in China. The highlight of our paper is that it offers a route which could settle the difficult problem but loan on credit. There are three platforms which can effectively settle SMEs financing difficulty with warehouse receipt. Platform 1 is a warehouse receipt management platform which manages SMEs movable property. Platform 2 is a P2P platform, or warehouse receipt financing platform. Platform 3 is a transaction platform of warehouse receipt. Future works have been put in the end

Light and Shadow of Artificial Intelligence: Transformative Journalism Opportunities and ethical dilemmas brought about by ChatGPT -- A research review based on the literature of domestic core journals

Since the release of ChatGPT in 2022, the related research fields have shown an explosive growth trend. Given this, this study attempts to sort out the current research systematically results on ChatGPT in journalism and communication by the literature review to expand the horizon of future research. Journalism and communication scholars have carried out a series of research on ChatGPT from three aspects: journalism reform, media theory, and media ethics. These researchers made certain progress in theory and practice. However, the existing researches still have problems, such as unclear concept definition, single research method, and confusing research topic. Future research should base on the perspective of journalism and communication disciplines, expand research methods and enrich research perspectives, and constantly upgrade ChatGPT research from phenomenon discussion to theoretical innovation and academic exchange.

Decision making in dynamic and interactive environments based on cognitive hierarchy theory, Bayesian inference, and predictive control

In this paper, we describe an integrated framework for autonomous decision making in a dynamic and interactive environment. We model the interactions between the ego agent and its operating environment as a two-player dynamic game, and integrate cognitive behavioral models, Bayesian inference, and receding-horizon optimal control to define a dynamically-evolving decision strategy for the ego agent. Simulation examples representing autonomous vehicle control in three traffic scenarios where the autonomous ego vehicle interacts with a human-driven vehicle are reported.Comment: 2019 IEEE Conference on Decision and Contro

Effect of n-3 polyunsaturated fatty acids on dopaminergic neurons in substantia nigra, brain inflammatory response and behavior in mice with Parkinson’s disease

Purpose: To examine the effect of n-3 polyunsaturated fatty acids (PUFAs) on dopaminergic neurons in substantia nigra, intracerebral inflammatory response and ethology in mice with Parkinson’s disease (PD). Methods: Four groups of male C57BL/6 mice (n = 48) were used: normal control, negative control, n3PUFA, and Madopa groups. Except for normal control group, all groups were given 6- hydroxydopamine hydrochloride (6-OHDA) to establish Parkinson’s mice model. The expressions of tyrosine hydroxylase (TH) and calcium-binding protein (CB) in substantia nigra dopaminergic neurons were determined with immunohistochemistry and Western blot. The contents of nitric oxide (NO), tumor necrosis factor (TNF-α) and interferon γ (IFN-γ) (indices of intracerebral inflammatory response) were measured. Tremor paralysis, moving grid number, standing times, swimming ability, and the number of rollers in each group were observed as indices of ethology. Results: The number of TH and CB-positive neurons in the substantia nigra of n-3PUFA-treated mice was significantly increased, relative to those in Madopa-treated mice (p < 0.05). The expressions of TH and CB proteins in substantia nigra in n-3PUFA group were markedly higher than the corresponding expressions in Madopa-treated mice (p < 0.05). Decreased levels of NO, TNF-α and IFN-γ levels were seen in 3PUFA group, when compared to mice in Madopa group, but higher behavioral scores were obtained in n-3PUFA-treated mice, relative to Madopa-treated mice (p < 0.05). Conclusion: The n-3PUFAs protect substantia nigra compact dopaminergic neurons against Parkinson’s disease, alleviate immune inflammation, and improve the coordination of limb movement. Thus, n-3PUFAs have potential therapeutic application in the management of Parkinson’s disease
