Comment les humains s’organisent-ils en sociétés ? Qu’appelle-t-on « familles » et comment se constituent-elles ? Quel regard et quels types d’analyse l’anthropologie propose-t-elle sur les systèmes de parenté, symboliques, politiques, religieux ?

L’anthropologie prospective nous aide à comprendre et à anticiper les phénomènes qui transforment nos modes de vie contemporains. Elle pose un regard transversal sur les actions, les pratiques et les dires des personnes avec lesquelles travaillent les chercheurs.

« Entrer en anthropologie », c’est accepter de changer son regard sur le monde et de se décentrer par rapport à ses habitudes. Si vous désirez comprendre un peu mieux le monde et ses changements contemporains, suivez ces chercheurs sur leur terrain et expérimentez d’autres repères culturels.

Durant ces quelques heures, vous serez amenés à débattre avec des professeurs et des étudiants autour de questions sur la famille, les migrations, les mondes virtuels ou encore les mondes des invisibles. Vous apprendrez les bases de l'approche anthropologique et ce qu'elle peut vous apporter en termes de réflexion sur votre propre société, sur votre vie et votre quotidienneté. Ce cours vous donne l’opportunité de comparer vos expériences et d’échanger vos points de vue avec des personnes d’autres horizons.

Les six semaines de cours aborderont une série de thématiques illustrées par des exemples concrets de modes d’existence divers et disséminés sur le globe. Des enseignants plongés au cœur des pratiques sociales et des enjeux politiques et économiques les plus variés partageront avec vous leur expérience après des années d'immersion sur les terrains de recherche qui les passionnent.

Si vous êtes curieux de tout et que comprendre votre propre société mais aussi des sociétés méconnues vous intéresse, ce cours s'adresse à vous !

How do human beings organize themselves in societies? What do we call “families” and how do they form? What type of analysis does anthropology propose about parenthood, and symbolic, political and religious systems?

Prospective anthropology helps us to understand and anticipate phenomena that transform our ways of life today. It gives a cross-cutting look at the actions, practices, and words of those people with whom anthropological researchers work.

To understand anthropology is to accept changing your view of the world, and to shift your perpsective of your own habits. If you want to understand the world and its contemporary changes more deeply, follow these researchers in their field, and experiment with other cultural references.

In this course, you will debate with professors and students about family, migrations, virtual worlds, and the world of « invisibles. » You will learn the basis of the anthropological approach and what it can bring you as a reflection tool about your own society and your everyday life. This course gives you the opportunity to compare your experiences and to exchange points of view with people from all around the world.

Professors immersed in the heart of various social practices, political and economic issues will share their experiences with you after years of research in fields that they are passionate about.

If you are curious about everything, and if you are interested in understanding your own society but also unknown societies, this course is for you!

You will get to know methods for eHealth service development and discuss basic requirements that are necessary to achieve sustainable eHealth applications for both clinical professionals and patients.

You will see examples of eHealth applications in different contexts and for different users. We will discuss questions such as:

• What is it that is so unique about the health sector?
• What factors are important - to avoid failures when implementing eHealth?
• What are usable tools for care professionals?
• How can patients best organize and use their own health data to improve their condition?

eHealth is a global issue but successful eHealth implementation is very dependent on the local context. At the end of the course you will have a basic understanding what eHealth is and how to set up eHealth strategies and discuss them in your specific context. You will also get to know success factors and pitfalls for the development of sustainable eHealth services and their implementation. 

This course is offered in collaboration with EIT Health.

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

This is part one of a two part sequence. Together these are hands-on, learn-by-doing courses that show you how to build solutions to real-world problems using embedded systems. In this course, we take a bottom-up approach to problem solving, building gradually from simple interfacing of switches and LEDs to complex concepts like a microcontroller-based pacemaker, digital lock, and a traffic light controller. 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 part 1 you will possess the knowledge to build your own traffic light controller 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 part 2. Students can pick and choose a subset of labs to achieve certification. The three labs that students found most rewarding in this part were designing the software algorithm for a demand pacemaker, interfacing switches and LEDS, and the finite state machine traffic light controller.

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.

We will explain how to start with raw data, and perform the standard processing and normalization steps to get to the point where one can investigate relevant biological questions. Throughout the case studies, we will make use of exploratory plots to get a general overview of the shape of the data and the result of the experiment. We start with RNA-seq data analysis covering basic concepts of RNA-seq and a first look at FASTQ files. We will also go over quality control of FASTQ files; aligning RNA-seq reads; visualizing alignments and move on to analyzing RNA-seq at the gene-level: counting reads in genes; Exploratory Data Analysis and variance stabilization for counts; count-based differential expression; normalization and batch effects. Finally, we cover RNA-seq at the transcript-level: inferring expression of transcripts (i.e. alternative isoforms); differential exon usage. We will learn the basic steps in analyzing DNA methylation data, including reading the raw data, normalization, and finding regions of differential methylation across multiple samples. The course will end with a brief description of the basic steps for analyzing ChIP-seq datasets, from read alignment, to peak calling, and assessing differential binding patterns across multiple samples.

Given the diversity in educational background of our students we have divided the series into seven parts. You can take the entire series or individual courses that interest you. If you are a statistician you should consider skipping the first two or three courses, similarly, if you are biologists you should consider skipping some of the introductory biology lectures. Note that the statistics and programming aspects of the class ramp up in difficulty relatively quickly across the first three courses. By the third course will be teaching advanced statistical concepts such as hierarchical models and by the fourth advanced software engineering skills, such as parallel computing and reproducible research concepts.

We begin with an introduction to the biology, explaining what we measure and why. Then we focus on the two main measurement technologies: next generation sequencing and microarrays. We then move on to describing how raw data and experimental information are imported into R and how we use Bioconductor classes to organize these data, whether generated locally, or harvested from public repositories or institutional archives. Genomic features are generally identified using intervals in genomic coordinates, and highly efficient algorithms for computing with genomic intervals will be examined in detail. Statistical methods for testing gene-centric or pathway-centric hypotheses with genome-scale data are found in packages such as limma, some of these techniques will be illustrated in lectures and labs.

If you’re interested in data analysis and interpretation, then this is the data science course for you.

Enhanced throughput: Almost all recently manufactured laptops and desktops include multiple core CPUs. With R, it is very easy to obtain faster turnaround times for analyses by distributing tasks among the cores for concurrent execution. We will discuss how to use Bioconductor to simplify parallel computing for efficient, fault-tolerant, and reproducible high-performance analyses. This will be illustrated with common multicore architectures and Amazon’s EC2 infrastructure.  

Enhanced interactivity: New approaches to programming with R and Bioconductor allow researchers to use the web browser as a highly dynamic interface for data interrogation and visualization. We will discuss how to create interactive reports that enable us to move beyond static tables and one-off graphics so that our analysis outputs can be transformed and explored in real time.

Enhanced reproducibility: New methods of virtualization of software environments, exemplified by the Docker ecosystem, are useful for achieving reproducible distributed analyses. The Docker Hub includes a considerable number of container images useful for important Bioconductor-based workflows, and we will illustrate how to use and extend these for sharable and reproducible analysis.

Introduction to Environmental Science, ENVX, was first offered in early 2015.

Environmental science is the study of patterns and processes in the natural world and their modification by human activity.  To understand current environmental problems, we need to consider physical, biological and chemical processes that are often the basis of those problems. This course will give you the skills necessary to address the environmental issues we are facing today by examining scientific principles and the application of those principles to natural systems.  This course will survey some of the many environmental science topics at an introductory level, ultimately considering the sustainability of human activities on the planet.

Environmental impacts on Earth come from the number of people and the amount and types of resources that they use. By applying scientific principles and considering real-world examples, we will examine:

• The field of environmental science and how to think like an environmental scientist
• The human population and the ways in which changes in the population affect the environment
• Agriculture, soils and the environmental implications of eating meat, vegetables, local, organic, sustainable, industrial and other types of food
• Non-renewable fossil fuels with a focus on coal, petroleum and natural gas and the benefits and consequences of using each
• Renewable fuels such as wind and solar and identify that even renewable “green” energy sources have impacts as well as benefits
• Biodiversity and global change, which are the integrating units of environmental science

Education method
The course will utilize video lectures, interviews with experts, readings, discussions, multiple choice and prompted discussions and one graded quiz per week. There will also be several optional live office hours on Google Hangouts.

Completion of self-assessments, contributions to discussion and quiz scores will determine the final grade. 

You love music. You listen to music all the time. Maybe you sing, play an instrument, or compose music. You don’t need to have musical talent to use music to enhance your well being, and even your health.

Learn simple techniques to enrich your mind, body, and spirit through music. The methods can be applied in your daily life, particularly when you are feeling down or stressed out. Developed by a board-certified music therapist and a vocalist/pianist/composer/recording artist specializing in Indian music, these strategies combine science with the wisdom of Eastern philosophy.

In the course, discover how to unlock your creativity. You will learn not only how to listen to music in a new way, but also how to listen to the impact that music has on you. You will find out how to care for yourself by practicing coping techniques that are supported by music that is special to you.

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). 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.

6.341x and this freely-available version were developed through the support and encouragement of the MIT Department of Electrical Engineering and Computer Science, the MIT Office of Digital Learning, and the MIT Research Laboratory of Electronics.
