Nutrition, Inequality and Agriculture: Contested Models of Degenerative Disease in Chiapas, Mexico
The industrial agro-food system has had two significant impacts on world public health: deteriorating human and animal nutrition due to poor food quality and the emergence of new infectious diseases arising from industrial animal production facilities and centralized food processing facilities. This situation is widely misrepresented in media coverage of public health issues. The corporate food system promotes the consumption of high levels of animal protein and processed foods
Ethno-linguistic Fragmentation, Discrimination, and Access to Clean Water in Mexico
Access to water is very unequal in Mexico and indigenous municipalities are particularly disadvantaged. The paper analyzes empirically the unequal access to water across Mexican municipalities and across individuals for the period of 2000-2005 using regression analysis. The contributions of this paper are two-fold. First, it expands the focus of the literature of ethnic fragmentation and public good provisions from level to distribution; and second, it presents an ethnic fractionalizat
Organization for Economic Co-Operation and Development (OECD)
The OECD groups 30 member countries sharing a commitment to democratic government and the market economy. With active relationships with some 70 other countries, NGOs and civil society, it has a global reach. Best known for its publications and its statistics , its work covers economic and social issues from macroeconomics, to trade, education, development and science and innovation. The site provies a myriad of resources on international econonmic development.
How to accelerate your Internet
Access to sufficient Internet bandwidth enables worldwide electronic collaboration, access to informational resources, rapid and effective communication, and grants membership to a global community. Therefore, bandwidth is probably the single most critical resource at the disposal of a modern organisation. The goal of this book is to provide practical information on how to gain the largest possible benefit from your connection to the Internet. By applying the monitoring and optimisation techniqu
Hodges Health Career - Care Domains - Model
Hodges’ Health Career (Care Domains) Model provides a conceptual framework upon which users can map problems, issues and solutions across four knowledge domains: Interpersonal; Sociological; Scientific; & Political (Autonomy). The public may also be taught to use the model, enabling engagement, understanding and concordance in planning and outcome evaluation. Brian Hodges' original notes, a resources page and links (800+) are included. Additional material on health informatics and the potenti
Dynamic Remodeling of Individual Nucleosomes Across a Eukaryotic Genome in Response to Transcription
The eukaryotic genome is packaged as chromatin with nucleosomes comprising its basic structural unit, but the detailed structure of chromatin and its dynamic remodeling in terms of individual nucleosome positions has not been completely defined experimentally for any genome. We used ultra-high–throughput sequencing to map the remodeling of individual nucleosomes throughout the yeast genome before and after a physiological perturbation that causes genome-wide transcriptional changes. Nearly 80%
Bioterrorism: plague as a biological weapon
Bioterrorism is the utilization of microorganisms or toxins in order to produce a disease and/or death in human beings, animals or plants. Different from conventional weaponry, relatively economic means are used that allow the elimination of living beings without destroying the surrounding atmosphere. The most probably method for spread of bioweapons is aerial transmission, continuing into water supplies and food. The CDC (US Centers for Disease Control and Prevention, Atlanta) has subdivided in
Water Science Curriculum
Water Science offers a two-semester water resource management curriculum for second year technical students or undergraduates in water resource management, water science, or environmental resource management programs. Water Science is divided into 6 major units. Each unit is divided into modules encompassing approximately a week's worth of lectures and labs.
In this hands-on OLogy activity, kids learn what happens when the rush of freshwater from a river collides with the gush of the ocean's tides. The activity begins with kid-friendly introductions to estuaries, salinity, and density. The illustrated, step-by-step directions show kids how to test the density of water at different levels of salinity and then investigate how a liquid's density affects the objects placed in it. It includes a fun look at the Dead Sea (Super Salty Sea) and why you can f
Journey to the Bottom of the Sea
This fun Web site is part of OLogy, where kids can collect virtual trading cards and create projects with them. Here, they learn about how living in the water differs from living on land. An ichthyologist first explains that ocean creatures have special features that allow them to breathe, eat, communicate, and move in water. (Each feature has its own trading card, which provides more detailed info.)Then students are challenged to "try to make the connection" by playing the Journey to the Bottom
Draw a Monarch Butterfly
This OLogy activity helps kids to learn about scientific illustrations by walking them through the steps for drawing a monarch butterfly. The activity begins by introducing kids to the importance of scientific illustration and why scientists prefer drawings to photographs. A photograph of a monarch and a printable monarch butterfly outline are included. In addition, students need color photographs, other research materials, paper, an eraser, and a variety of pencils. The process of creating the
Eye on Einstein
This OLogy activity challenges students to find nine inventions that Einstein's ideas helped to create. The activity begins with an illustration of Al's Junk Shop. Mixed in with his junk are a Global Positioning System, CD player, computer, calculator, scanner, laser pointer, TV, and representations of both laser surgery and nuclear energy. After making a mental list of their nine choices, students can click to a second page to check their answers. Each invention has a rollover note about how Ei

How does the temperature of the Great Lakes change over time?
This classroom activity allows students to use water surface temperature, bathymetric data and weather data to look at trends in the water temperature of the Great Lakes. The exercise asks students to make predictions, and then use the data to answer questions. The site contains everything that is needed for the exercise, including student handouts, maps, links to data sources, and background information and questions for discussion.
This 16-slide PowerPoint presentation discusses the characteristics of granitoid rocks including geographic occurrence, rare earth elements, enclave characteristics, pressure-temperature conditions, the influence of water, and tectonic setting.

Field Project Tutorials: A Virtual (Structural) Field Project
This virtual five-day field mapping project allows students to construct a geological map from data provided by the web site. Students collect geologic, structural, paleontologic, strain and microstructural data observed at specific localities. Students are then able to derive a structural history for the area, including a field map, stereographs, and deformation plots. The site contains photographs and images, data, and all information that is needed to complete the exercise. It also provides s
Coastal Wave Mechanics
This site features Flash animations and a QuickTime movie that illustrate how waves and water molecules behave along the shore and in deep water settings. Animations depict the orbital motion of water molecules and show cross sections of waves at varying depths. These resources are suitable for use in lectures, labs, or other teaching activities.
