A Temporal Investigation of Crash Severity Factors in Worker-Involved Work Zone Crashes: Random Parameters and Machine Learning Approaches:
Reason:
In the context of work zone safety, worker presence and its impact on crash severity has been less explored. Moreover, there is a lack of research on contributing factors by time-of-day. To accomplish this, first a mixed logit model was used to determine statistically significant crash severity contributing factors and their effects. Significant factors in both models included work-zone-specific characteristics and crash-specific characteristics, where environmental characteristics were only significant in the daytime model. In addition, results from parameter transferability test provided evidence that daytime and nighttime crashes need to be modeled separately. Further, to explore the nonlinear relationship between crash severity levels and time-of-day, as well as compare the effects of variables to that of the logit model and assess prediction performance, a Support Vector Machines (SVM)
What is meant by machine learning approach?
Machine Learning is an AI technique that teaches computers to learn from experience. Machine learning algorithms use computational methods to “learn” information directly from data without relying on a predetermined equation as a model.

Answer:
Self-made entrepreneur
Explanation:
A self-made entrepreneur is somebody who started his own business from scratch, without any foreign help. The business usually starts as an idea which is often something the entrepreneur is passionate about. In case of Jules Sylvester the passion were his reptiles. He cleverly turned his passion into his business, knowing that his knowledge and his love for animals are invaluable for his enterprise. As many self-made entrepreneurs, he started his venture without any financial help from others, and he might have faced various risks and obstacles at the beginning.
Some alternatives that Reagan proposed were:
- Cancelling out the federal paid leave days after Christmas and New Year.
- Using the money the federal government would pay workers on MLK Day for a cause Dr. King supported.
<h3 /><h3>Reagan and Martin Luther King Day </h3>
- Reagan was concerned about having a federal holiday in honor of Martin Luther King.
- He worried that the government would lose money from having to pay employees on a day when an important figure would be celebrated as this was not done much before.
Reagan's administration then offered the above alternatives but pressure on him led him to approving the federal holiday that is now Martin Luther King Day.
