The strategic plan will be the roadmap for a public relations campaign and will integrate the key concepts offered through the four courses.
For more than 3.5 billion years microbes and their communities (microbiomes) have shaped the Earth and its inhabitants. A holistic understanding of the role of our planet’s microbiomes is key to addressing the challenges facing humanity in the 21st century. By analyzing their constituent genes, RNA molecules, proteins, and chemical metabolites, we are beginning to gain profound insights into the crucial role played by microbiomes in human health and disease. The microbiota associated with crops and soils provide nitrogen, phosphorus, and other essential nutrients, decompose pollutants, and inhibit the activity of pathogens. Through photosynthesis, microbes in the oceans remove 50% of atmospheric carbon dioxide and generate the same amount of oxygen. Given the extensive roles of microbes, a greater appreciation of microbiome function would help us to address the challenges that we face to supply food, energy, and clean water while maintaining and improving the health of our population and ecosystems - actions which are crucial to achieving sustainability. Rapid advances in the microbiome field have been made possible by interdisciplinary research. If we are to harness microbiome function to achieve sustainability, we need to promote such integrative thinking. Thus, an interdisciplinary strategy that promotes collaboration and creative problem-solving will also be introduced.

Persuasive communication is essential to any professional workplace. From a simple email request for your colleague to help you, to developing a presentation for the board of directors, these are acts of communication that require a good degree of persuasion. Even the process of entering the workforce requires effective persuasive communication, for in the act of writing your resume, cover-letter, or in the interview process, you are essentially persuading the potential employer to hire you.By the end of this course, you will be able to structure and express your ideas in a convincing and persuasive manner in writing, apply basic principles of persuasive writing to convince different sets of audiences at the globalised workplace, and learn to engage in persuasive and credible communication across different cultures in a complex globalised environment.Persuasive and Credible Communication: An OverviewIn the first part, we will analyse and discuss theoretical concepts of both persuasion and credibility. Principles of Persuasive WritingIn the second part, we will establish some basic rules of effective writing and examine how writing can be made more persuasive.Persuasive Writing in a Globalised WorldIn the last part of the course, we will situate persuasive and credible writing in the larger context of a globalised world. We will tackle issues such as persuasion and credibility across cultures.
The primary goal of the course is to enable learners to understand what semiconductors are and exactly why they are useful to the electronics industry. We will learn why some materials are insulators and others are conductors, why some materials are transparent and others opaque, and we will learn how electrons move inside materials. The course explores situations where the conductivity of an insulator can be drastically changed, such as the situation inside a bolt of lightning or inside a semiconductor. Semiconductor physics textbooks are typically highly mathematical, and often rely on a foundation of solid state physics. This course, however, focuses less on mathematics and more on understanding at an intuitive level why materials have the properties that they do. For instance, silicon is a very important material in the modern electronics industry, and by the end of this short course, the reason why silicon is special will be clear.This course is suitable for a first year university undergraduate student, or an older learner who did not study electrical engineering or materials science. High school-level physics is the assumed background. By the end of the course, learners will understand all of the fundamental terminology used in the semiconductor industry, and will be able to perform basic calculations.

We start from the very beginning in electronics. What is voltage? What does it physically mean? What is current? What happens in a circuit and how can things like power consumption be calculated?In this course we learn how to analyze circuits through a variety of methods, including the Kirchoff voltage and current laws, superposition, Node Voltage Analysis, Thevenin’s Theorem and concepts such as impedance matching and maximum power transfer. These are useful to predict the performance of circuits.We look at various types of equipment used for electrical circuit measurements, including power supplies, multimeters, oscilloscopes, and function generators. At the end of the course, students will be able to use resistors, capacitors, inductors, diodes, and batteries in circuits as well as analyse and design circuits containing these components. One of the circuits built in the course is a light sensing circuit.
