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:
True
Explanation:
Klatzke (2008) in her research found that leave-takers craft different messages for different audiences upon their exit to facilitate certain impressions. This is because often times, leave-takers sees their exit from the company as an event that will not affect their future endeavors, such as leave-taker telling the colleagues at work that the reason for leaving is because of theie ineffective manager, while the may tell the manager, that the reason for leaving the company is for higher pay or new challenges.

<em>Answer:</em>
<em>Canadians; Asians </em>
<em>Explanation:</em>
<em>As per the question, Canadians are likely to describe "self-relevant events" from a participant's viewpoint but Asians would describe the same from observer's viewpoint because of the fact that Canadian countries follow the individualistic culture or viewpoint whereas the Asian countries follow the collectivistic culture or viewpoint. According to the researchers, the individualistic culture people tend to think about oneself whereas collectivistic culture people tend to think about the group and society.</em>
The urban Poor enjoy better access to quality education than the rural counterparts. Another reason is, rural poverty is temporary as the rural poor can migrate to urban areas to seek employment but, on the other hand, urban poverty is permanent.
