Probabilistic Reasoning
The theme of probability and its reasons is perfectly described in two sources. One of them is the chapter in the book Fundamentals of Biostatics by Bernard Rosner where the author gives several clear and interesting examples and defines the essence of probability in different cases. And another source is
Chapter Three in Fundamentals of Biostatics by Bernard Rosner
Rosner’s chapter helps to understand that probability is an important issue to be taken into consideration while calculating and interpreting p-values in various statistics tests (Rosner 43). The author finds it useful to discuss the multiplication law of probability with such variables as the conditional probability of occurrence and what has already happened (Rosner 48) and the additional law of probability under which the same variable should not be mutually exclusive.
The issue of probability is based on two types of events, dependent and independent, and the level of probability usually depends on the dependence that may be observed between these two events. The application of these ideas helps to realize that conditional probabilities may change their direction regarding the conditions created.
Probabilistic Reasoning by M. Anthony Kapolka
The author of this audio lecture decides to follow the achievements in the source mentioned above, so, the third chapter of Fundamentals of Biostatics is the main basis. Still, the powerful aspect of this source is that the author introduces more real-life examples and provides the listener with a chance to understand the urgency of probability level as well as the possibility to interfere with the probability calculations which are important for the field of statistics and medicine where human lives are considered.
Decision Support & Expert System
Three sources are used to investigate the theme of expert systems. One of them is the lecture about decision support systems which aim at supporting decision-making activities, and expert systems developed in the middle of the 1970s to promote the analysis of the problems. Some information is taken from Wikipedia, and some information can be unreliable.
The readings from Biomedical Informatics (Chapters 4 and 20) by Schortliffe and Ciimo identify the importance of the decision-making process and its impact on human activities. The article by Faughnan explains the peculiarities of the new “diagnostic expert system for internal medicines” called Iliad 3.1. which may be used to improve the treatment process (Faughnan 1).
Networks
The videos are helpful sources of information to understand how important the networks can be in the system. Health promotion is possible through the Internet, and the computer networks offered to people. With the help of networks, medical workers may reach their patients and deliver the necessary information within a short period. The chapters in Biomedical Informatics make the idea of networks’ use in life clearer explaining that computer networks help to spread information and connect people who share similar concerns (Schortiffe and Cimino 522).
Risk & Security
The theme of security in different medical institutions is crucial indeed: patients want to be sure that their information remains to be private, and medical workers have to elaborate on the risks which may appear in their work. The chapters from Biomedical Informatics as well as the video offered help to understand how risk and security have to be considered by the medical workers and which strategies are more appropriate for particular situations.
