This environmental studies course is intended to introduce you to some of the basic principles in environmental studies, and how those are manifested in urban, rural and natural areas throughout the world.

Through observation, discussion, and creation of digital content, you will explore and share environmental challenges facing your local environment and create a global learning and action community.

Rather than simply offering a long list of the problems we face, this course will take a solutions-focused approach.

This course will introduce the concept of environmental ethics, a philosophy that extends the ethical concepts traditionally applied to human behavior to address the entire natural world. The course will outline the history of environmental ethics, discuss the idea of environmental justice, and explore how our views about the natural world have changed over time. Though environmental ethics is considered a fairly new branch of scientific philosophy, it has actually been debated avidly since the 19th century. From the frontier era of the developing United States through to the modern-day environmental movement, you will identify and analyze the key pioneers and events in the move to help preserve our planet for future generations and species. You will also explore the notion of environmental justice and how this impacts certain social groups, particularly in poorer communities throughout the world. Finally, you will familiarize yourself with the major environmental laws and world views that support the envir…

Human societies have always been dependent upon local and regional environments for critical natural resources, and loss of these resources (either due to environmental changes or human overuse) has often reduced a society’s resilience to future challenges.  When resilience decreases, the risk of societal collapse increases.  Today, our globalized, highly connected societies have increased access to environmental resources, yet they leave us more vulnerable to disruptions and disasters that begin in other regions or systems.  By understanding how our societies are connected to each other and to the environment, we can better manage our interactions so that they do not increase the potential for societal collapse.  This course will use a complex systems theory perspective to investigate how coupled human-environment systems interact to either increase or decrease their risk of collapse.  This complex systems approach works across many disciplines, so that human-environment linkages can be understood fro…

Systematic reviews and meta-analyses are useful for evidence-based clinical and public health practice. The widespread and growing application of systematic review methods for the synthesis of evidence on important or pressing research and clinical questions underscore the need for health-care professionals to understand and critique this research design. This course will provide a detailed description of the systematic review process, discuss the strengths and limitations of the method, and provide step-by-step guidance on how to actually perform a systematic review and meta-analysis. Specific topics to be covered include: formulation of the review question, searching of literature, quality assessment of studies, data extraction, meta-analytic methods, assessment of heterogeneity and report writing. The course will also cover statistical issues such as selection of statistical models for meta-analysis, practical examples of fixed and random effects models, best evidence syntheses (qualitative systematic reviews) as well as examples of methods to evaluate heterogeneity and publication bias. STATA statistical software will be used to perform meta-analysis during the computer lab, along with tutorials on how to effectively use tools such as PubMed for conducting reviews.

Malaria, HIV/AIDS, Influenza, Measles - we’re in a constant battle against infectious diseases. This is a course about the dynamics of such diseases - how they emerge, how they spread around the globe, and how they can best be controlled.

This course consists of an international analysis of the impact of epidemic diseases on western society and culture from the bubonic plague to HIV/AIDS and the recent experience of SARS and swine flu. Leading themes include: infectious disease and its impact on society; the development of public health measures; the role of medical ethics; the genre of plague literature; the social reactions of mass hysteria and violence; the rise of the germ theory of disease; the development of tropical medicine; a comparison of the social, cultural, and historical impact of major infectious diseases; and the issue of emerging and re-emerging diseases.

“If history is our guide, we can assume that the battle between the intellect and will of the human species and the extraordinary adaptability of microbes will be never-ending.” (1)

Despite all the remarkable technological breakthroughs that we have made over the past few decades, the threat from infectious diseases has significantly accelerated. In this course, we will learn why this is the case by looking at the fundamental scientific principles underlying epidemics and the public health actions behind their prevention and control in the 21st century.

This course covers these four topics:

1. origins of novel pathogens;
2. analysis of the spread of infectious diseases;
3. medical and public health countermeasures to prevent and control epidemics;
4. panel discussions involving leading public health experts with deep frontline experiences to share their views on risk communication, crisis management, ethics and public trust in the context of infectious disease control.

What can we do to prevent outbreaks of infectious diseases from becoming epidemics or pandemic? In this course, you’ll learn the facts about infectious diseases and medical responses. We'll focus on the public health laws and policies that provide the framework for effective prevention, like quarantine laws, drug development policies, and bioterrorism and biodefense.

This course explores public health—both locally and globally—through the lens of epidemiology.

Each mammalian cell has the same genes, yet performs distinct functions. This is achieved by epigenetic control of gene expression; the switching on and switching off of genes. This course will cover the principles of epigenetic control of gene expression, how epigenetic control contributes to cellular differentiation and development, and how it goes wrong in disease.

This course will cover many aspects of equine nutrition ranging from anatomy and physiology of the gastrointestinal tract to dietary management of horses/ponies affected with nutrition-related disorders. This is course is designed for self-directed study with minimal tutor input, and as such emphasis is placed upon peer discussions of the topics presented in each section of the course. This course is not designed to have a large amount of tutor input as this is an open access course that attracts tens of thousands of participants. However, tutors will endeavour to answer the main queries relating to the understanding of the lecture materials and to provide a summary of the key questions raised in each of the weekly topics and clarification of any misunderstandings.
