The immune system is very powerful and very versatile. Most people forget it is just as capable of destroying your own cells as it is those of a pathogen.

In this biology and life sciences course, we’ll flip the basic question of, “How does the immune system protect you?” to, “How can your immune system endanger you?”

First, we will look at basic mechanisms that determine whether the immune system is roused to action or instructed to stand down, including the roles of inflammasomes and T regulatory cells and the results of mutation to genes and their importance in producing regulatory proteins. Then, we will apply these insights to explain the etiology and treatment of autoimmune diseases and look at a variety of misdirected immune attacks, including allergies, attacks on red blood cells and cellular responses that can produce damage ranging from rashes to autoimmune cellular destruction. Finally we will discuss the protection of transplants from an immune system that views them as foreign invaders instead of necessary replacements.

Thanks to the economic liberalization in several countries over the last few decades, the world has witnessed an exponential increase in the free flow of capital across countries, even more so in emerging economies. This has resulted in a globally interconnected ecosystem of banks and financial markets engaged in foreign exchange transactions that are continuously growing in volume, sophistication and complexity. That, in turn, has attracted a plethora of participants whose explicit intention is to either profit from or hedge against the heightened level of risks in the foreign exchange markets.  

This economics and finance course will unravel those complexities and help you gain a comprehensive understanding of foreign exchange markets: the underlying theories, the instruments traded and how the associated risks and potential adverse outcome are addressed/redressed using several techniques such as currency derivatives.

This Islamic finance and banking course gives an overview of the basics of Islamic insurance, mutual and investment funds. In this course, you will learn about The Concept of Takaful Ta’awuni (collaborative), The Basis for Takaful, Takaful vs Conventional Insurance, The Tabarru or donation - based Takaful Model.

You will also learn about Islamic Perspectives on Mutual Funds and Real Estate Investment Trust (REIT) and Islamic Investment Funds.

No previous knowledge is needed.

Why Islamic finance is important for the global financial industry

Islamic finance has grown rapidly, with the trend expecting to continue. Although the concept has been around for much longer, Islamic finance only attained a formal status in Muslim-majority countries in the 1970s. Today, it has become a global phenomenon, eliciting increasing interest around the world, including from non-Muslim countries like the United Kingdom, Luxemburg, Kenya, South Africa, and Hong Kong. Islamic finance has grown into a huge industry with total worldwide assets estimated at about US$2 trillion.

Islamic finance has the potential to contribute to higher and more inclusive economic growth by increasing access of banking services to underserved populations. In addition, it has the potential to promote financial stability due to its risk-sharing feature and its financing being asset-backed and thus fully collateralized. Moreover, Islamic banks offer profit-sharing and loss-bearing accounts that can help mitigate losses and contagion in the event of banking sector distress. These are all indications that Islamic finance is converging to the global finance industry and hence all international finance professionals should be aware of Islamic finance.

Architecture engages a culture’s deepest social values and expresses them in material, aesthetic form. In this course, you will learn how to “read” architecture as a cultural expression as well as a technical achievement. Vivid analyses of exemplary buildings from a wide range of historical contexts, coupled with hands-on exercises in drawing and modeling, bring you close to the work of an actual architect or historian.

Architecture is one of the most complexly negotiated and globally recognized cultural practices, both as an academic subject and a professional career. Its production involves all of the technical, aesthetic, political, and economic issues at play within a given society. Over the course of ten modules, we’ll examine some of history’s most important examples that show how architecture engages, mediates, and expresses a culture’s complex aspirations.

The first part of the course introduces the idea of the architectural imagination as a faculty that mediates sensuous experience and conceptual understanding. Two examples of the architectural imagination—perspective drawing and architectural typology—are explored through video presentations and hands-on exercises. You will be introduced to some of the challenges involved in writing architectural history, revealing that architecture does not always have a straightforward relationship to its own history.

In the second set of modules, we address technology as a component of architecture’s realization and understanding. Architecture is embedded in contexts where technologies and materials of construction—glass and steel, reinforced concrete—are crucial agents of change. But a society’s technology does not determine its architectural forms. You will discover ways that innovative technology can enable and promote new aesthetic experiences, or disrupt age-old traditions. You will witness architecture’s ways of converting brute technical means into meaningful perceptions and textures of daily life. The interactions of architecture and modern technologies changed not only what could be built, but also what kinds of constructions could even be thought of as architecture.

The final set of modules confronts architecture’s complex relationship to its social and historical contexts and its audiences, achievements, and aspirations. As a professional practice deeply embedded in society, architecture has social obligations and the aesthetic power to negotiate social change; to carry collective memories; even to express society’s utopian ideals. You will learn about what we call architecture’s power of representation, and see how architecture has a particular capacity to produce collective meaning and memories.

Learn how electronic gadgets are designed, developed, and built as embedded systems that shape the world.

This is part two of a two part sequence. In this class, we will use interrupts to design a range of real-time systems including an audio player, a data acquisition system, a control system, and an interactive game. This is a hands-on, learn-by-doing course that shows you how to build solutions to real-world problems using embedded systems. These courses use a bottom-up approach to problem solving, building gradually from simple interfacing of switches and LEDs to complex concepts like display drivers, digital to analog conversion, generation of sound, analog to digital conversion, motor control, graphics, interrupts, and communication. We will present both general principles and practical tips for building circuits and programming the microcontroller in the C programming language. You will develop debugging skills using oscilloscopes, logic analyzers, and software instrumentation. Laboratory assignments are first performed in simulation, and then you will build and debug your system on the real microcontroller. At the conclusion of this course you will possess the knowledge to build your own arcade-style game from the ground up.

This is the fourth time we have offered this course. Since the reviews have been overwhelmingly positive we do not plan major changes over the previous offerings of the course. We did however break the large class into two smaller classes. There are eight labs in part 1 and six labs in this class. Students can pick and choose a subset of labs to achieve certification. The three labs that students found most rewarding were the hand-held video game, generating sound using a digital to analog convertor, and creating a smart object using Wifi communication.

To complete this course, you will be required to purchase a Texas Instruments TM4C123 microcontroller kit and a few electronic components. This microcontroller has a state-of-the-art ARM Cortex-M4 processor.

We will provide instructions about purchasing the kit and installing required software at: http://edx-org-utaustinx.s3.amazonaws.com/UT601x/index.html.

To make sense of modern China, you simply cannot ignore Marxism. ‘From Mao to Now’ presents current topics that anyone who wishes to engage with China should know.

Rather than praising or condemning, the course focuses on building a deeper understanding of this history through two interwoven elements.

The first structures the course in terms of some ‘red tourism’ to the sites important to the communist revolution in the first half of the twentieth century.

Much of the course footage was filmed on location in China, including Shaoshan, Ruijin, Yan’an and important locations in Beijing, such as Tiananmen and the Nationalities Museum (minzuyuan).

The second element of the course will take those experiences and use them to help answer some fundamental questions:

• Is China socialist or capitalist today, or is it perhaps both at one and the same time?
• Is there such a thing as Chinese socialist democracy, and, if so, what is it?
• Does China have its own theory of human rights, drawn from the long Chinese tradition and Marxism?
• If the Chinese state is a form that has not been seen before, then what is it?

You Can Innovate prepares you for the MIT Global Entrepreneurship Bootcamp!

The bootcamp is a one-week, intensive entrepreneurship education program that challenges you to start a company in 5 days. The Bootcamp offers you the unique opportunity to be mentored by MIT faculty and MIT alumni entrepreneurs and investors as you begin your new entrepreneurial journey

This course is not only for those planning to attend the Bootcamp, this course will teach you how to develop your ideas for innovative ventures whether you continue to the Bootcamp or not.

We’ll let you in on a secret. Innovation happens everywhere. More often than not, it is about ordinary people solving problems that matter to them personally. This could be you.

Examples of user innovation are infinite. A surfer created the GoPro to take “selfies” while surfing. A student came up with Dropbox after forgetting his flash drive. Two broke entrepreneurs rented out their living room to help pay rent, and Airbnb was born. They’ll share their paths to startup success.

Based on the work of Eric von Hippel, the founding scholar of user innovation, this course will help you think about what problems you should choose to solve and how to share your innovations with others.

This course is terrific for:

• Aspiring entrepreneurs searching for ideas for innovation;
• Inveterate inventors searching for ways to diffuse their innovations;
• Entrepreneurship educators looking for practical methods for meaningful ideation.  

You Can Innovate has also been valuable for policymakers who work to energize the innovation ecosystems in their regions and for innovators within established companies working to anticipate or, better, productively engage with disruptive innovations.  

In the Verified track, the MIT course team composed of Faculty, Teaching Fellows, and Alumni Mentors, will review, grade and provide feedback on your assignments.  In the Verified track you will also be enrolled in weekly review and discussion sessions.  

You can innovate.

Offered by the Ross School of Business at the University of Michigan in collaboration with National Arts Strategies, this course focuses on equipping leaders in the cultural sector with the critical skills for inspiring employee engagement and performance while motivating people to adjust behavior and embrace change.

You will learn how to create a shared vision for your team and effectively communicate it to your teammates. You will also learn how to set effective goals and expectations in a way that best enables your team to attain the shared vision. Finally, you will understand the most important needs and drivers of performance across cultures, and will learn to align rewards with desired behaviors so that your teammates are motivated to attain the team’s objectives.

Motivation represents a crucial challenge for contemporary organizations. A recent Gallup poll revealed that only 13% of workers worldwide exhibit high levels of engagement and motivation. We will show you why these motivation problems are not simply due to a “bad” or “unmotivated” team member. Rather, motivation is very much driven by what work conditions we create for our teammates, how we structure goals and objectives, and how we reward people for the accomplishment of those goals. This course will help you diagnose and solve motivation problems so that you can bring out the best in your people.

This course features lessons from both University of Michigan, Ross School of Business faculty and practitioners in the arts and culture field. Leaders such as Franci Phelan (Kennedy Center), Aaron Dworkin (UM School of Music, Theatre and Dance) and Tim Cynova (Fractured Atlas) share their stories on effective leadership and HR practices in the cultural sector.
