Senior management aspirations of managers and professionals: a career decision-making perspective
A number of demographic, technological, and economic shifts have redefined the composition of todayâ s workforce and the concept of a career. Corporate downsizing and the delayering of management have affected the career advancement prospects available to individuals pursuing a managerial career path. The traditional means of rewarding employees through promotion appears to be an infrequent option in the current business environment. Subsequently, the level of competition among those individua
Patient Communication Skills, 2009
The materials on this page represent a curriculum for teaching effective patient communication to dentistry students. These techniques could be useful for other healthcare providers, as well: medical students, nursing students, public health providers, and in-practice health care providers. There are two main types of resources: performance keys and videos. Performance Keys are text documents that articulate key patient interaction skills, and give examples of more and less effective techniques
Novel organic-inorganic hybrid mesoporous materials and nanocomposites
Organic-inorganic hybrid mesoporous materials have been prepared successfully via the nonsurfactant templated sol-gel pathway using dibenzoyl-L-tartaric acid (DBTA) as the templating compound. Styrene and methyl methacrylate polymers have been incorporated into the mesoporous silica matrix on the molecular level. The synthetic conditions have been systematically studied and optimized. Titania based mesoporous materials have also been made using nonionic polyethylene glycol surfactant as the pore
In-vitro tiered approach alternative to live animal testing for determination of ocular or dermal ir
There is a continual need for information concerning the potential for chemicals, if inadvertently splashed into the eyes, to cause effects from irritation to total blindness. This information is currently generated by exposing the eyes of live rabbits to the chemical. As can be imagined, this often results in severe distress to the animal while generating information that we have shown to be discernable without putting any animals at risk. This may be accomplished by replacing the live animal t
Natural Inquirer Journals: Wildland Fire
This edition of the Natural Inquirer is all about wildland fire. You will learn about the benefits of wildland fire, as well as some of its dangers. You will learn what fire scientists are learning about wildland fire. They are learning, for example, 1) that wildland fire should not be completely eliminated from natural environments, but it should be managed; 2) how to predict which weather conditions most favor a wildfire being started; 3) about the relationship between wildland fires and globa
Essential Science for Teachers: Earth and Space Science
In-depth interviews with children that uncover their ideas about the topic at hand.,The interviewer identifies the student's ideas about the interior of the earth being made up of hot magma by asking her to draw a picture. When the student mentions volcanoes, the interviewer probes further to ask her to explain what a volcano is.
Natural magic informs every function of our bodies, our life span and the way we perceive.
Essential Science for Teachers: Physical Science: Session 2. The Particle Nature of Matter: Solids,
What simple idea links together all of chemistry and physics? How can a close study of the macroscopic differences among solids, liquids, and gases support a microscopic model of tiny, discrete, and constantly moving particles? In this session, participants learn how the "particle model" can be turned into a powerful tool for generating predictions about the behavior of matter under a wide range of conditions.,This segment shows an example of probing questions about phenomena to find out if the
Earth Exploration Toolbook Chapter: Investigating Earthquakes: GIS Mapping and Analysis
This activity describes the technique of preparing latitude-longitude based data so it can be imported into a geographic information system (GIS). The chapter describes the steps to create a map to display data and guides users through some basic geographic analyses. The focus of the chapter's case study is earthquake prediction. Users download and format near real-time and historical earthquake data from the USGS. They import the data into ArcVoyager Special Edition GIS software, and analyze pa

EngineSim and RangeGames Downloads
EngineSim was developed at the NASA Glenn Research Center in an effort to foster hands-on, inquiry-based learning in science and math. EngineSim is a simulator that models the design and testing of jet engines. The program works in two modes: Design Mode or Tunnel Test Mode. In the Design Mode, you can change design variables including the flight conditions, the engine size, the inlet performance, the turbo machinery compressor and turbine performance, the combustors or burner performance, or th
Allometry: Size and its consequences or... Why aren't there 20 foot tall ants?
Evolution has resulted in changes in the sizes and forms of organisms. Everything about the biology of an animal, including its physiology, anatomy, and ecology, is influenced by its body size. Frequently there seem to be limits on the sizes that different organisms can attain, even when larger size might be thought to be evolutionarily advantageous. Often an increase or decrease in size is correlated with a change in proportions. Understanding the significance of a particular morphology or inte
Culturing Experimental Organisms for Use in Teaching Biology
Methods for the collection and the culturing of a variety of experimental organisms used in teaching biology are discussed. The organisms include protozoans, hydra, planaria, vinegar eels, aquatic snails, Daphnia, brine shrimp, frogs, turtles, flesh flies, and Tenebrio. Culturing parameters, overall care, handling, diet, feeding procedures, and specific environmental conditions are examined.
Symba: a Framework to Support Collective Activities in an Educational Context
Symba is a Web-based framework designed to support collective activities in a learning context. It has been constructed with a double objective, (1) make students explicitly work out their organization and (2) provide tailorability features to allow the students to decide about the tools and resources they want to be accessible in order to achieve the tasks they have defined. Symba dissociates an organizational level and an activity level. The organization level allows students to organi
New Media and Open and Distance Learning: New challenges for Education in a Knowledge Society
The "digital society" provides not only with new technology, but also with new concepts. Information plays a central role and becomes a valuable good, but knowledge cannot be reduced to information, and one aim for educators is to contribute in a "knowledge society", not only an "information society". A knowledge society is structured in networks, enriching the traditional hierarchies; a knowledge society promotes a kind of "collective intelligence". In such a society, open and distance learning

Commemoration: Visual texts
This unit explores the commemoration of war through treating two war memorials – the Sandham Memorial Chapel and the Royal Artillery Memorial – as 'visual texts'. By helping you to respond to visual cues the unit aims for you to develop your understanding of these memorials, not only as memorials, but as artefacts or 'made objects'. It does this through consideration of such factors as the location of the monument; its function and purpose; its symbolism or realism; use of materials and over
Using Insects in the Classroom
Insects are an excellent resource for science education. Many insects are easily maintained in the classroom and can happily thrive despite being handled and kept in captivity. The remarkable diversity in form and function of commonly found insects promotes interest and enthusiasm in observing the natural world. Insects can also be used to model a variety of scientific principles. The objectives of this page are to give educators basic information about insects and ideas on how to use insect
