The course provides a well-researched and comprehensive introduction to the UN system. The course consists of an introduction to the complex UN system and its history, as well as a series of snapshots of key UN functions, which are used to explore important UN themes and help students develop important analytical, communication and policy skills. The course as a whole is designed for people interested in learning more about the UN system, assuming an interest but without the necessary previous knowledge, while offering enough relevant research and new critical perspectives, and will also appeal to those with more experience or academic familiarity with the topic. The main aim of the course is to provide this broad introduction in a self-contained but in-depth manner, as well as the important practical skills needed to understand and discuss UN affairs, and perhaps lay the foundation for more active involvement in the future - either in civil society or in further study.

Clinical trials are experiments designed to evaluate new interventions to prevent or treat disease in people. Interventions evaluated may be drugs, devices (such as a hearing aid), surgeries, behavioral interventions (such as a smoking cessation program), population health programs (such as cancer screening programs), or health care delivery systems (such as hospital specialty care units). We consider clinical trials to be experiments because investigators, rather than patients or their doctors, choose the treatments patients receive. Results from randomized clinical trials are generally considered the highest level of evidence for determining the effectiveness of a treatment because the trials include features that ensure that the benefits and risks of the treatment are assessed objectively and unbiased. The FDA requires that drugs or biologics (such as vaccines) be proven effective in clinical trials before they can be marketed in the United States. This course will explain the basic principles of designing randomized clinical trials and how they should be presented. In the first part of the course, students will be introduced to the terminology used in clinical trials and some common designs used in clinical trials, such as parallel and crossover. We will also explain some of the mechanics of clinical trials, such as randomization and blinding of treatment. In the second half of the course, we will explain how clinical trial results are analyzed and interpreted. Finally, we will cover the main ethical issues involved in conducting experiments on humans.

In this course, you'll learn how to keep track of the different versions of your code and configuration files using a popular version control system (VCS) called Git. We'll also go through how to set up an account with a service called GitHub so that you can create your very own remote repositories to store your code and configuration. Throughout this course, you'll learn about Git's core functionality so you can understand how and why it's used in organizations. We'll look into both basic and more advanced features, like branches and merging. We'll demonstrate how having a working knowledge of a VCS like Git can be a lifesaver in emergency situations or when debugging. And then we'll explore how to use a VCS to work with others through remote repositories, like the ones provided by GitHub. By the end of this course, you'll be able to store your code's history in Git and collaborate with others in GitHub, where you'll also start creating your own portfolio! In order to follow along and complete the assessments, you'll need a computer where you can install Git or ask your administrator to install it for you.

Probabilistic graphical models (PGMs) provide a rich framework for encoding probability distributions in complex domains: joint (multivariate) distributions over a large number of random variables that interact with each other. These representations are at the intersection of statistics and computer science, drawing on concepts from probability theory, graph algorithms, machine learning, and more. They are the basis for state-of-the-art methods in a wide variety of applications, such as medical diagnostics, image understanding, speech recognition, natural language processing, and many, many others. They are also a fundamental tool in the formulation of many machine learning problems. Applied learning project Through a variety of lectures, quizzes, programming assignments, and exams, students in this specialization will practice and master the fundamentals of probabilistic graphical models.

In this course, we will attempt to "understand Einstein," with a particular focus on the special theory of relativity that Albert Einstein, as a twenty-six-year-old patent clerk, introduced in his "miracle year" of 1905. Our goal will be to penetrate beyond the myths and popularized representations of relativity to gain a deeper understanding of both Einstein and the concepts, predictions, and strange paradoxes of his theory. Some of the questions we will consider include: How did Einstein arrive at his ideas? What was the nature of his genius? What is the meaning of relativity? What is "special" about special relativity? Why did it initially seem like the theory was dead on arrival? What does it mean that time is a "fourth dimension"? Can time really flow more slowly for one person than for another, or can the sizes of objects change depending on their speed? Is time travel possible, and if so, how? Why can't things travel faster than the speed of light? Is it possible to travel to the center of the galaxy and back in one lifetime? Is there any evidence to definitively support the theory, or is it mostly speculation? Why didn't Einstein win a Nobel Prize for his theory of relativity? About the Instructor: Dr. Larry Lagerstrom is the Director of Academic Programs at Stanford University's Center for Professional Development, which offers graduate certificates in artificial intelligence, cybersecurity, data mining, nanotechnology, innovation, and management science.
