As emissions of heat-trapping bases accumulate in our atmosphere, Earth's polar regions are warming more quickly than at lower latitudes. The rapid environmental changes that result from this warming can have a significant impact on the physical and mental health of rural Alaskans: unpredictable weather and changes in the seasons have made harvesting food more difficult, hazardous, and stressful. The risk of physical injury has also increased, as poor ice, extreme weather, and coastal erosion bring new travel hazards. Increasingly difficult harvest conditions for fish, shellfish, berries, caribou, and sea mammals have also increased concerns about food security. Additionally, declines in snow pack, the threat of drought, changes in lake and river conditions, and damage and disruptions to community water systems have prompted concerns of water security. The climate-related challenge faced by Alaskas tribal health system is to recognize new health stressors and community vulnerabilities, and then find healthy adaptation strategies in an increasingly uncertain future.
The purpose of this lesson, from Science NetLinks, is to use the Internet to explore how the immune system functions in a variety of allergic reactions. In middle school, students should have had experiences studying the healthy functioning of the human body. In high school, students should relate their knowledge of normal body functioning to situations in which functioning is impaired due to environmental or hereditary causes. Also at this level, students should try to find explanations for diseases in physiological, molecular, or system terms. Since the primary purpose of this lesson is to explore the role of immune responses in allergic reactions, students should already have a working knowledge of body systems, and the immune system in particular.
These 3 lessons are for high ABE/low ASE students at a level D-E Reading level to practice identifying key points in video and text and analyzing the causes and effects of social issues, and identifying solutions to these problems. By watching two short videos and reading EPA materials on the effects of lead exposure and a short article on the specific drinking water crisis in Flint, MI, students will examine key issues, analyze the problem and its causes, identify approaches to solving this problem and ones like it in other locations, and apply this approach to other scenarios that are relevant to their immediate lives.
Healthcare professionals around the world are experiencing increasing pressures from patients, communities, governments and payers to demonstrate value. Controlling costs, providing high quality outcomes, assuring access, and enhancing patient satisfaction have become leading issues. In addition, services increasingly are provided within the context of multi-disciplinary teams and complex organizational and financial arrangements. Fiscal and other resource constraints abound. Meeting these challenges within healthcare settings requires leadership and managerial skills in addition to clinical expertise.
This seminar-style course challenges students to look closely at the environment of Baltimore City's complex food systems and to consider what it would take to improve these systems to assure access for all to nutritious, adequate, affordable and sustainably produced food. Students "go backstage" with tour guides at sites including a supermarket, a corner store, an emergency food distribution center, and a farm connected to the city school system. Students learn about the types of food available at these sites, who uses them, relevant aspects of their operations, and site-relevant key barriers to and opportunities for providing access to healthier food, ideally with reduced environmental harm. They also conduct oral history interviews about food with elderly city residents to understand how food access has changed over the years. Class discussions, lectures, readings, and guest speakers support critical thinking, and provide background and frameworks for understanding the experiential sessions. Lectures and discussions consider applicability of lessons gained from the study of Baltimore to other area food systems. Throughout, students consider the relative impacts of access, demand, and stakeholder interests, and consider the relative strengths of voluntary, governmental, legal and other strategies. For their final papers, students apply the Intervention Decision Matrix to selected aspects of the city's food systems and food environments, identifying challenges and opportunities for change, incorporating lessons learned from other food systems and programs, and discussing implications beyond Baltimore .

When a pregnant woman doesn't take care of herself, you might expect her baby to suffer from birth defects or childhood illnesses. But what happens when her baby grows up? In this Science Update, you'll hear about a recent study that suggests that malnutrition in the womb can come back to haunt you well into adulthood.
Building on lessons learned over several summers, Kristin Raab—Health Impact Assessment and Climate Change Program Director in the Environmental Health Division of Minnesota’s Department of Health—packaged information from diverse communities into a cohesive toolkit that communities of all sizes can use to prepare for heat waves. The Minnesota Extreme Heat Toolkit describes changing weather conditions in Minnesota, the magnitude of potential health consequences from extreme heat, and key steps communities can take to prevent heat-related illnesses and deaths. The toolkit acknowledges that extreme heat response plans will vary with the size of the community and the habits of its residents: examples from the mostly rural Olmsted County and the urban centers of Saint Paul and Minneapolis illustrate a range of community plans that could be useful in Minnesota and beyond.
This task was developed by high school and postsecondary mathematics and health sciences educators, and validated by content experts in the Common Core State Standards in mathematics and the National Career Clusters Knowledge & Skills Statements. It was developed with the purpose of demonstrating how the Common Core and CTE Knowledge & Skills Statements can be integrated into classroom learning - and to provide classroom teachers with a truly authentic task for either mathematics or CTE courses.
In this course, we will seek to interpret capitalism using ideas from biological evolution: firms pursuing varied strategies and facing extinction when those strategies fail are analogous to organisms struggling for survival in nature. For this reason, it is less concerned with ultimate judgment of capitalism than with the ways it can be shaped to fit our more specific objectives for the natural environment, public health, alleviation of poverty, and development of human potential in every child. Each book we read will be explicitly or implicitly an argument about good and bad consequences of capitalism.
This course introduces students to the origins, concepts, and development of community-based primary health care through case studies from both developing and developed countries. As in clinical bedside teaching, we use real cases to help students develop problem-solving skills in practical situations. We also discuss participatory approaches in the organization and management of health services and other factors such as equity, socio-cultural change, environmental protection, and the process of community empowerment.Included among this course's lecture materials are several recorded presentations by Carl Taylor, a giant in the field of international health. Dr. Taylor recorded the presentations for this course in January of 2008, just 2 years before he passed away in February of 2010.
The objective of this presentation is to use three illustrative case studies to reinforce basic concepts and principles of terrorism preparedness and response, as well as to identify some specific practical considerations. These case studies will illustrate: (1) Plausible scenarios, (2) Typical first response activities, (3) Critical issues on-the-fly, and (4) Considerations for planning.

Considers appropriate instruments to assess growth and development. Evaluates efficacy of popular early intervention programs designed to enhance development in at-risk populations of children.
A recent report in the journal Pediatrics questioned the effectiveness of over-the-counter children's cough medicines. In this Science Update, you'll hear more about the study, and why some medicines may have escaped this sort of rigorous testing.
In this lecture, Professor Brieger discusses some of the lessons he learned during his 26-year experience working in Nigeria and his subsequent work with a wider variety of African nations, focusing on on tropical diseases and their associated social, cultural, and behavioral aspects.
In the first part of the lesson, students calculate their yearly exposure rate to harmful high-energy radiation and cumulative effects over time. They then use the information to evaluate the various sources of radiation that are of greatest concern for them. In the second part of the lesson, students learn that spacecraft and other objects in space must be concerned with the same kinds of radiation to which humans are exposed. The MESSENGER spacecraft will orbit Mercury and be subjected to much more intense solar radiation than it would near Earth. Students discuss the notion that even though some of the radiation is needed to study the properties of the planet, too much of it can be quite damaging.
