Answer:
Explanation:
Like charges repel each other; unlike charges attract. Thus, two negative charges repel one another, while a positive charge attracts a negative charge.
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.

When an individual gives something to someone else but expects nothing in return, this is an example of Generalized reciprocity.
Generalized reciprocity is the phenomenon in that people deal with others in the same way that others treated them in the past. besides the behavioral results, whether or not aim facts additionally manipulate generalized reciprocal behavior remains uncertain.
Generalized reciprocity is gift giving without the expectancy of a direct return. as an instance, if you are shopping with a pal and also you buy him a cup of espresso, you could assume him to buy you one in return at some time in the future
Generalized reciprocity: This form regularly entails exchanges within families or pals. there may be no expectation of a back prefer; alternatively, human beings without a doubt do something for any other character based on the belief that the opposite individual might do the equal element for them. This sort of reciprocity is related to altruism.
