The Architectural Imagination | HarvardX on edX | Course About Video
 
02:05
Learn fundamental principles of architecture — as an academic subject or a professional career — from a study of history’s important buildings. Take this course free on edX: https://www.edx.org/course/architectural-imagination-harvardx-gsd1x#! ABOUT THIS COURSE 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. WHAT YOU'LL LEARN How to read, analyze, and understand different forms of architectural representation Social and historical contexts behind major works of architecture Basic principles to produce your own architectural drawings and models Pertinent content for academic study or a professional career as an architect

Enroll at: https://www.edx.org/course/u-lab-transforming-business-society-self-mitx-15-s23x This highly experiential course is based on Theory U, a framework, method, and way of connecting to the more authentic aspects of our self. It introduces the variable of consciousness into management and the social sciences, and proposes that the quality of the results that we create in any kind of social system is a function of the quality of awareness, attention or consciousness that the participants in the system operate from. This approach to leading change is practiced by business, government, and civil society leaders around the world – many of whom you will meet during this course. During these six weeks, we will look at today’s environmental, social, and spiritual-cultural challenges and explore why it is that our societies collectively create results that, individually, nobody wants. We will introduce you to frameworks that enable you to identify the deeper structures and paradigms of thought that give rise to these issues. And we will invite you into a learning environment that is more personal, practical, relational, mindful, collective, and transformative than what you may have experienced in other online courses.

Introduction to Control System Design - A First Look | MITx on edX | Course About Video
 
02:21
Learn the theory and practice of controller design by building and then position-stabilizing a propeller-levitated arm. Take this course free on edX: https://www.edx.org/course/introduction-control-system-design-first-mitx-6-302-0x#! ABOUT THIS COURSE Have you wondered about the design strategies behind temperature controllers, quad-copters, or self-balancing scooters? Are you interested in robotics, and have heard of, or tried, “line-following" or “PID control” and want to understand more? Feedback control is a remarkably pervasive engineering principle. Feedback control uses sensor data (e.g. brightness, temperature, or velocity) to adjust or correct actuation (e.g. steering angle, motor acceleration, or heater output), and you use it all the time, like when you steer a bicycle, catch a ball, or stand upright. But even though applications of feedback are very common, the subject is an uncommonly compelling example of mathematical theory guiding practical design. In this engineering course we will introduce you to the theory and practice of feedback control and provide a glimpse into this rich and beautiful subject. Each week we will begin with a mathematical description of a fundamental feedback concept, combined with on-line exercises to test your understanding, and will finish with you designing, implementing, measuring, and analyzing a hardware system, that you build, for controlling a propeller-levitated-arm feedback system. You will not need a background in calculus or software engineering to succeed in this class but you should be familiar with algebra and mechanical forces, have some exposure to complex numbers, and be comfortable with modifying mathematical formulas in short computer programs. This is a lab course, and in order to complete the weekly assignments, you will need to purchase/acquire a list of parts. To make sure you receive your parts before the class begins, you should register promptly, so that you can access the lists of parts and international vendors. WHAT YOU'LL LEARN - How to set up a control system and understand and optimize its performance (the Arduino-controlled propeller-levitated arm) - Modeling Feedback Control systems Using Difference Equations - What unstable systems are like, practically and mathematically - How to measure control system performance - How proportional, delta (aka derivative) and summation (aka integral) feedback reduce tracking errors and increase disturbance rejection

ContractsX: From Trust to Promise to Contract | HarvardX on edX | Course About Video
 
02:39
Contracts are a part of our everyday life, arising in collaboration, trust, promise and credit. How are contracts formed? What makes a contract enforceable? What happens when one party breaks a promise? Take this course free on edX: https://www.edx.org/course/contract-law-trust-promise-contract-harvardx-hls2x-0 ABOUT THIS COURSE Learn about contracts from Harvard Law Professor Charles Fried, one of the world’s leading authorities on contract law. Contracts are promises that the law will enforce. But when will the law refuse to honor a promise? What happens when one party does not hold to their part of the deal? We are exposed to contracts in all areas of our life — agreeing to terms when downloading a new computer program, hiring a contractor to repair a leaking roof, and even ordering a meal at a restaurant. Knowing the principles of contracts is not just a skill needed by lawyers, it illuminates for everyone a crucial institution that we use all the time and generally take for granted. This contract law course, with new materials and updated case examples, is designed to introduce the range of issues that arise when entering and enforcing contracts. It will provide an introduction to what a contract is and also analyze the purpose and significance of contracts. Then, it will discuss the intent to create legal relations, legality and morality, and the distinction between gifts and bargains. The course also investigates common pitfalls: one-sided promises, mistake, fraud, and frustration. With the knowledge of what makes contracts and how they can go wrong, Professor Fried will discuss remedies and specific performance. Finally, Professor Fried will introduce how contracts can create rights for third parties. The course’s instructor, Charles Fried, has been teaching at Harvard Law School for more than 50 years and has written extensively on contracts. Not only is Professor Fried a leading authority on contract law, but he also utilizes a story-telling approach to explaining the topic, which creates a unique and interesting class experience. WHAT YOU'LL LEARN - A theoretical background of contracts, trust, and promise - Contracts the government will stand behind and those it won’t - Illusory promises, offer and acceptance - The limitations of contract law - Writing and Interpretation of contracts - Key concepts including mistake, fraud, and frustration; remedies and specific performance; and third parties

Intro to Probability - The Science of Uncertainty | MITx on edX | About Video
 
02:05
Introduction to Probability - The Science of Uncertainty An introduction to probabilistic models, including random processes and the basic elements of statistical inference. Register for Introduction to Probability from MIT at http://edx.org/courses. About this Course The world is full of uncertainty: accidents, storms, unruly financial markets, noisy communications. The world is also full of data. Probabilistic modeling and the related field of statistical inference are the keys to analyzing data and making scientifically sound predictions. Probabilistic models use the language of mathematics. But instead of relying on the traditional "theorem - proof" format, we develop the material in an intuitive -- but still rigorous and mathematically precise -- manner. Furthermore, while the applications are multiple and evident, we emphasize the basic concepts and methodologies that are universally applicable. The course covers all of the basic probability concepts, including: - multiple discrete or continuous random variables, expectations, and conditional distributions - laws of large numbers - the main tools of Bayesian inference methods - an introduction to random processes (Poisson processes and Markov chains) The contents of this course are essentially the same as those of the corresponding MIT class (Probabilistic Systems Analysis and Applied Probability) -- a course that has been offered and continuously refined over more than 50 years. It is a challenging class, but it will enable you to apply the tools of probability theory to real-world applications or your research. Course Staff: John Tsitsiklis John Tsitsiklis is a Professor with the Department of Electrical Engineering and Computer Science, and a member of the National Academy of Engineering. He obtained his PhD from MIT and joined the faculty in 1984. His research focuses on the analysis and control of stochastic systems, including applications in various domains, from computer networks to finance. He has been teaching probability for over 15 years. Patrick Jaillet Patrick Jaillet is a Professor of Electrical Engineering and Computer Science and Co-Director of the MIT Operations Research Center. He obtained his PhD in Operations Research at MIT.

Learn by doing: analyze, design, and build electronic interfaces between sensors and a microcontroller to build a robot or your own creation in this hands-on lab course. Enroll at https://www.edx.org/course/electronic-interfaces-bridging-physical-uc-berkeleyx-ee40lx Follow edX on Twitter: www.twitter.com/edxonline Follow edX on Facebook: www.facebook.com/edx About this Course EE40LX teaches the fundamentals for engineering electronic interfaces between the physical world and digital devices. Students can expect to cover the material of a traditional first circuits course with a project-based approach. We start with essential theory and develop an understanding of the building blocks of electronics as we analyze, design, and build different parts of a robot from scratch around the Texas Instruments MSP430 microcontroller. Useful mathematics will be discussed where appropriate, but only a working knowledge of high school algebra is required to follow along. More experienced students will be able to dig deeper into optional modules that cover advanced concepts in analog circuit design. Some of these have been developed by practicing engineers in industry who know the tricks of the trade and have decided to share some of their insights to enhance the course. The philosophy of the course is to learn by doing, so every lecture features a substantial lab component. Students are invited to work together in small groups to build their own robots along with the instructors. There will also be individual circuit analysis and design exercises to reinforce the theories presented in the course. Those who successfully complete each theory assignment and earn a passing grade will get an honor code certificate from BerkeleyX. Additionally, a kit of electronic components costing under $40 USD will be available from Newark element14. Ordering pages will be made available for North America, Europe, and Asia at the beginning of December, so please be patient. The kit is not necessary to obtain a certificate for this run of the course, but it will greatly enhance your learning experience. Additionally, some mechanical components are required to complete the robot as presented in the course. Also, the lab experience will be most effective if you have access to a digital multimeter and an oscilloscope. The NI MyDAQ with NI Ultiboard has been made available for students who would like to use this relatively inexpensive ($199 USD) measurement equipment to follow along with the course. Creativity is encouraged! Students that are willing to work outside the bounds of the class to develop their own inventions will get the most out of this guided learning experience. MyDAQ Information Those who do not have access to an oscilloscope or a digital multimeter might consider purchasing a MyDAQ to enable measurements. The video modules use the MyDAQ and the NI Ultiboard as measurement equipment to help debug the circuit. National Instruments has made available the MyDAQ and NI Ultiboard as a bundle, as well as the NI Ultiboard alone for students enrolled in this course. Take a look at the MyDAQ ordering page. Parts Kit Information The parts included in the construction of the robot can be purchased at Newark's landing page: North America Europe (coming soon) Asia-Pacific (coming soon) This kit is optional, but highly recommended to get the most out of the course. For students interested in sourcing their own parts from other distributors, here is the complete parts list with manufacturer information:

02:22
Street-Fighting Math Teaches, as the antidote to rigor mortis, the art of educated guessing and opportunistic problem solving. Register for Street Fighting Math from MIT at http://www.edx.org/courses. About this Course Too much mathematical rigor teaches rigor mortis: the fear of making an unjustified leap even when it lands on a correct result. Instead of paralysis, have courage: Shoot first and ask questions later. Although unwise as public policy, it is a valuable problem-solving philosophy and the theme of this course: how to guess answers without a proof or an exact calculation, in order to develop insight. You will learn this skill by mastering six reasoning tools---dimensional analysis, easy cases, lumping, pictorial reasoning, taking out the big part, and analogy. The applications will include mental calculation, estimating population growth rates, understanding drag without differential equations, singing musical intervals to estimate logarithms, approximating integrals, summing infinite series, and turning differential equations into algebra. Your learning will be supported by regular readings that you discuss with other students, by short tablet videos, by quick problems to help you check your understanding, by weekly homework problems, review and and a final exam. You will work hard, and, by the end of the course, have learned a rough-and-ready approach to using mathematics to understand the world. All required readings are available within the courseware, courtesy of The MIT Press. A print version of the course textbook, Street-Fighting Math, is also available for purchase. The MIT Press is offering enrolled students a special 30% discount on books ordered directly through the publisher's website.

An introduction to the study of bioethics and the application of legal and ethical reasoning. Take this course free on edX: https://www.edx.org/course/bioethics-law-medicine-ethics-harvardx-hls4x#! ABOUT THIS COURSE Bioethics provides an overview of the legal, medical, and ethical questions around reproduction and human genetics and how to apply legal reasoning to these questions. This law course includes interviews with individuals who have used surrogacy and sperm donation, with medical professionals who are experts in current reproductive technologies like In Vitro Fertilization and Preimplantation Genetic Diagnosis, and bioethicists and journalists who study the ownership and use of genetic information within human tissue. Additional Harvard colleagues will also share with you their thoughts on topics such as disability law as it relates to reproductive technology. While the law and ethics surrounding these technologies are a central component to this course, we also show you examples of the deeply personal and human side of these issues. Throughout the course, and with the help of law students, we will discuss leading legal cases in this field, which will illuminate the types of questions the law has struggled with – stretching and evolving over time. From the famous Baby M surrogacy case, to cases on the paternity of sperm donors, to a case related to the ownership of human tissue turned into a commercial product, and others. We will show you the ethical, legal, and rhetorical underpinnings, which have served as the basis for various court decisions over the past 20 or 30 years. We will also explore potential future technologies and their implications for society: genetic enhancements to increase our intelligence, let us live a hundred years longer, or make us immune to diseases – and the possibility of creating animal-human hybrids, for example a mouse with a humanized brain. The content within this course is intended to be instructive, and show how legal reasoning has been applied, or could be applied, to questions related to parenthood, reproduction, and other issues surrounding human genetic material. The material organized within this course should be considered an authoritative overview, but is not intended to serve as medical or legal advice. This course is designed for a diverse audience including, but not limited to, law students, prospective law students, medical professionals, as well as members of the general public interested in questions and topics related to surrogacy, parenthood, genetic and reproductive technology, ownership of genetic material, and more. You do not need any background in law, medicine, philosophy, or really any subject to enjoy this course. This course is meant to be an introduction for anyone interested in these topics. WHAT YOU'LL LEARN - How the reproductive technology industry works, and issues raised related to buying and selling human reproductive materials - The law and ethics of surrogacy - Civil lawsuits when things go wrong with reproductive technology: wrongful birth and wrongful life lawsuits - The law and ethics of sperm donation and the legal status of sperm donors - Ethical and legal issues raised by human enhancement - The law and ethics of mixing human and animal genetic material - The ownership of human tissue and its underlying genetic information

When you complete a verified certificate in this course it will feature original artwork with both Stan Lee’s and Michael Uslan’s signature. About this Course Join the Smithsonian, and comic book industry legend Stan Lee, to explore the history of the comic book and the rise of superheroes. The ancient gods of Egyptian, Greek and Roman myths still exist, but today, they have superpowers, human foibles and secret identities. They come from comic books and graphic novels, and have taken over pop culture on the stage, screen, video games, and animation. From Superman® and Spiderman®, to The Avengers® and The Hulk® and beyond, who are these heroes? And, how have they evolved from folklore and myth, across all cultures and religions? Learn from Smithsonian and industry experts including: Stan Lee, who created the modern superhero template. His early comics featuring Spiderman, Iron Man®, The Hulk, Thor®, and The Avengers led Marvel to success. He continues to reinvent himself to create modern global superheroes and appear in cameos in superhero films and TV, such as Avengers: Age of Ultron. Michael Uslan, executive producer of top grossing, award winning movies, including The Dark Knight series, Lego® Movie, the animated Batman films and Batman® VS Superman. In this course, we explore the following questions: Why did superheroes first arise in 1938 and experience what we refer to as their “Golden Age” during World War II? Why did the superhero genre ebb and flow in popularity over the decades? How have comic books, published weekly since the mid-1930’s, mirrored a changing American society, reflecting our mores, slang, fads, biases and prejudices? Why was the comic book industry nearly shut down in the McCarthy Era of the 1950’s? How did our superheroes become super-villains in the eyes of the government, clergy, educators, and parents of the mid-20th Century? When and how did comic books become acceptable again, and eventually become valid teaching tools in universities and schools? When and how did comic book artwork become accepted as a true American art form as indigenous to this country as jazz? Finally, when and how did comic books become “cool” and the basis for blockbuster movies, hit TV series, top-selling video games, and acclaimed animation, while also impacting fashion and style- and even the moral and ethical codes of children- around the globe?

Early Christianity: The Letters of Paul The course "Early Christianity: The Letters of Paul" explores the context of these letters in the Roman Empire and the impact of these powerful texts today. Register for Early Christianity: The Letters of Paul from Harvard University at http://edx.org/courses. About this Course The letters of Paul are the earliest texts in the Christian scriptures, written by a Jew at a time when the word "Christian" hadn't yet been coined. What is the religious and political context into which they emerged? How were they first interpreted? How and why do they make such an enormous impact in Christian communities and in politics today? Archaeological materials and ancient writings will help you to enter the ancient Mediterranean world and to think about religious groups, power, poverty, health, and the lives of elites and slaves in the Roman Empire. We'll explore how immediately controversial these letters were, and how these letters are used today to debate relations between Christians and Jews; issues such as love, law, and grace; and topics such as charismatic Christianity, homosexuality, and women's religious leadership. Whether you've been studying Paul's letters for years or are merely curious about what Christian scriptures are, this course will provide you with information to deepen your understanding of the ancient contexts and present-day controversies about these texts. Course Staff: Laura Nasrallah Laura Nasrallah, Professor of New Testament and Early Christianity Nasrallah's research and teaching bring together New Testament and early Christian literature with the archaeological remains of the Mediterranean world. She also investigates how these texts make an impact in religious communities and in politics today. Her books include An Ecstasy of Folly: Prophecy and Authority in Early Christianity, Christian Responses to Roman Art and Architecture: The Second-Century Church Amid the Spaces of Empire, and two co-edited volumes, Prejudice and Christian Beginnings: Investigating Race, Gender, and Ethnicity in Early Christian Studies and From Roman to Early Christian Thessalonikē: Studies in Religion and Archaeology. She's currently at work on a commentary on 1 Corinthians and a book titled Archaeology and the Letters of Paul. Her awards include a Henry Luce III Fellowship in Theology and a fellowship from the American Association of University Women.

The Art of Poetry | BUx on edX | Course About Video
 
03:23
The Art of Poetry The art of poetry gives pleasure and invites knowledge. This course is based on a conviction that the more you know about an art, the more pleasure you will find in it. Register for the Art of Poetry from Boston University at https://www.edx.org/course/bux/bux-arpo222x-art-poetry-1565 About this Course Poetry lives in any reader’s voice, not necessarily in performance by the poet or a trained actor. The pleasure of actually saying a poem, or even saying it in your imagination—your mind’s ear—is essential. That is a central idea of “The Art of Poetry,” well demonstrated by the videos at favoritepoem.org: the photographer saying Sylvia Plath’s “Nick and the Candlestick,” the high school student saying Langston Hughes’ “Minstrel Man.” Those readers base what they say about each poem upon their experience of saying it. The course is demanding, and based on a certain kind of intense, exigent reading, requiring prolonged— in fact, repeated— attention to specific poems. The readings will include historical poems, as well as contemporary work. The focus will be on elements of the art such as poetry’s historical relation to courtship; techniques of sound in free verse; poetry’s relation to music; the nature of greatness—with only incidental attention to schools of poetry, categories and trends. Students are encouraged to think truly, carefully and passionately about what the poem says, along with how the poem feels in one’s own, actual or imagined voice. As Robert Pinsky says, in the Preface to Singing School: “this anthology will succeed if it encourages the reader to emulate it by replacing it . . . create your own anthology.” In a comparable way, this course hopes to inspire a lifelong study of poetry.

A Global History of Architecture — Part 1 | MITx on edX | Course About Video
 
03:09
A Global History of Architecture — Part 1 This course is a history of architecture from a global perspective. About this Course How do we understand architecture? One way of answering this question is by looking through the lens of history. This course will examine architecture through time, beginning with First Societies and extending to the 15th century. Though the course is chronological, it is not intended as a linear narrative, but rather aims to provide a more global view, by focusing on different architectural "moments." The lectures will give students the appropriate grounding for understanding a range of buildings and contexts. The material in the lectures will be supplemented by readings from the textbook A Global History of Architecture. Each lecture analyzes a particular architectural transformation arising from a dynamic cultural situation. How did the introduction of iron in the ninth century BCE impact regional politics and the development of architecture? How did new religious formations, such as Buddhism and Hinduism, produce new architectural understandings? What were the architectural consequences of the changing political landscape in northern Italy in the 14th century? How did rock-cut architecture move across space and time from West Asia to India to Africa? How did the emergence of corn impact the rise of religious and temple construction in Mexico? These are typical questions that the lectures will address. All required readings are available within the courseware, courtesy of Wiley. Print or electronic versions of the A Global History of Architecture, Second Edition and Architecture of First Societies are also available for purchase. The course is aimed for a general audience at the undergraduate level with an interest in history. All lectures will be in English.

Introduction to Philosophy: God, Knowledge and Consciousness This course will focus on big questions. You will learn how to ask them and how to answer them. Register for Introduction to Philosophy: God, Knowledge and Consciousness from MIT at https://www.edx.org/course/mitx/mitx-24-00x-introduction-philosophy-god-2481 About this Course This course has two goals. The first is to introduce you to the things that philosophers think about. We will look at some perennial philosophical problems: Is there a God? What is knowledge, and how do we get it? What is the place of our consciousness in the physical world? Do we have free will? How do we persist over time, as our bodily and psychological traits change? The second goal is to get you thinking philosophically yourself. This will help you develop your critical reasoning and argumentative skills more generally. Along the way we will draw from late, great classical authors and influential contemporary figures. If you wish to take the course as a 'verified' student (technological checks guarantee it is you taking the course) then please register as Verified below. It will cost you $50. Upon completing the course you will receive a certificate that says that you completed the course as a 'verified' student. Otherwise you can take the course as a non-verified student (you guarantee it is you taking the course by signing an honor code) for free. You will receive a certificate that says that you completed the course as a non-verified student. Next Spring (2015) we will be offering 24.118x Paradox and Infinity for the first time. Next Fall (2015) we will be offering 24.09x Minds and Machines for the first time. By completing all three courses as a verified student you will be eligible for a Philosophy X series certificate.

Enroll in Discrete-Time Signal Processing from MITx at https://www.edx.org/course/discrete-time-signal-processing-mitx-6-341x ↓ More info below. ↓ Follow on Facebook: www.facebook.com/edx Follow on Twitter: www.twitter.com/edxonline Follow on YouTube: www.youtube.com/user/edxonline Discrete-Time Signal Processing A focused view into the theory behind modern discrete-time signal processing systems and applications. About this Course 6.341x is designed to provide both an in-depth and an intuitive understanding of the theory behind modern discrete-time signal processing systems and applications. The course begins with a review and extension of the basics of signal processing including a discussion of group delay and minimum-phase systems, and the use of discrete-time (DT) systems for processing of continuous-time (CT) signals. The course develops flow-graph and block diagram structures including lattice filters for implementing DT systems, and techniques for the design of DT filters. Parametric signal modeling and the efficient implementation of DT multirate and sampling rate conversion systems are discussed and developed. An in-depth development of the DFT and its computation as well as its use for spectral analysis and for filtering is presented. This component of the course includes a careful and insightful development of the relationship between the time-dependent Fourier transform and the use of filter banks for both spectral analysis and signal coding. 6.341x is organized around eleven units each typically consisting of a set of two to four topics. The source material for learning each topic includes suggested reading in the course text, clarifying notes, other related reading, and video excerpts and will include an interactive on-line discussion forum. The course text is the widely used text by Oppenheim and Schafer (third edition), available on the course website in viewable format. The video segments are adapted from live video recordings of the MIT residential course. Each topic includes a set of automatically-graded exercises for self-assessment and to help in digesting and understanding the basics of the topic, and in some cases to preview topics. A typical unit in the course concludes with a set of more extensive problems to help in integrating the topics and developing a deeper understanding. Automatic grading of your answers to these problems as well as solutions will be provided. Cite this course as Alan V. Oppenheim and Thomas A. Baran, 6.341x Discrete-Time Signal Processing, on edX, Spring 2015. https://www.edx.org/course/mitx/mitx-6-341x-discrete-time-signal-4396

The main aim of the course, An Introduction to Global Health, is to describe and analyze variation in health between and within countries. This will provide an understanding of causes of the variation. The course will include measurements and determinants of health. Further, the course offers a public health perspective of the global burden of diseases. The course will specifically address: Maternal and Child Health; Sexual reproductive health and rights; Major infectious disease - malaria, TB, HIV, pneumonia; Non communicable disease; Mental health; Disasters; Injuries; Health systems and financing; and Health policy. Analysis will be done from a gender and equity perspective. The course combines different teaching methods: lectures, self-study, and exercises using gapminder tools (Gapminder.org) to analyze indicators. An added value is that the course is open to participants from different parts of the world, which creates an intercultural learning and teaching environment. By the end of this course, you should have a good idea of how these key global health challenges are approached by different stakeholders. You will have developed an understanding of what kind of solutions exist today and hopefully you will be curious as to how to make positive difference in the world. What you'll learn: How the countries of the world changed from being developing or developed countries to now being a on a continuum of socio-economic level How falling child mortality and fertility will end the fast growth of the world population in this century How economic level, inequity and policy of nations determines the health of its citizens How the global burden of diseases change from mainly infections to now mainly non-communicable diseases How global policies such as UNs Development Goals, trade regulation, patents and human rights influence health
