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:
A) decrease; appreciate
Explanation:
Everything else held constant, if a central bank makes an unsterilized sale of foreign assets, then the domestic money supply will decrease and the domestic currency will appreciate.
Any attempt by the central bank to make an unsterilized sale of foreign assets, the resultant effect will be a decrease in domestic money supply but an appreciation of domestic currency.
Answer:
D. Microexpressions often give away momentary lapses in the control of our expressions
Explanation: The difference is who sues, as well as the potential penalties. Namely, when it comes to a civil case, a citizen can file a lawsuit against another citizen, say a neighbor, or against an organization, a company, and the like. In such cases, the sentence is usually not a prison sentence, but some other form of punishment as compensation, etc.
In a criminal case, it is usually the government, i.e. the competent prosecutor's office, which sues the citizen. This is usually considered a lawsuit against criminal activity by individuals or a group, which may be harmful to others or to the state as a whole. In that case, the sentence is usually imprisonment or some other type of punishment provided for the crime.
