Hull's Theory | in Chapter 09: Motivation | from Psychology: An Introduction by Russ Dewey Hull's Theory Biological motives are those that are "wired into the nervous system." They include hunger, thirst, the pursuit of pleasure, and the avoidance of pain. How was Hull's theory ambitious? Hull's theory was one of the first systematic attempts to explain motivation. What stereotype is due partly to Hull's theory? Research on Hull's theory is largely responsible for an old stereotype of experimental psychologists as lab-coated figures watching rats run through mazes for cheese reinforcement. Why should students know about Hull's theory? For beginning students, Hull's theory remains relevant in several ways. The Hullian Approach In the 1930s, Clark Hull undertook to construct a grand theory that he thought would unite all psychology. Clark Hull What concept was featured in Cannon's book? Scientists knew about biological regulation as early as the mid-1800s, but the concept of homeostasis was not widely discussed until Walter B. Where did motivation come from, according to Hull?

Extract DNA from your Halloween pumpkin. Click on the photo for a larger image. Towards the end of October we start seeing lots of recipes for pumpkin this and pumpkin that. This one is different. We're going to extract the DNA from a pumpkin. What you need: A pumpkin. What we do with all that stuff Cut the pumpkin into small chunks that fit in the blender. Add about a half cup of water to the pumpkin chunks, and a tablespoon of salt. Now we add a whole bunch of dishwashing detergent. Next we filter the puree using the coffee filter and funnel. Now it is time to get the liquor out of the freezer. For this part, a shot-glass would be appropriate. Pour some of the filtered pumpkin juice into the container. Now, tilt the container and very gently pour some of the alcohol slowly so that it forms a layer on top of the juice, and does not mix. After a few seconds, you will see a ghostly layer of DNA form between the juice and the alcohol. Pumpkin is made of water, cellulose, sugars, proteins, salts, and DNA.

Répertoire des outils 2.0 gratuits en français Le Répertoire des Outils 2.0 en français est un nouvel annuaire qui compte une vingtaine de catégories de services en ligne et logiciels à utiliser dans un cadre pédagogique (initiation, formation, enseignement…). Cette initiative de qualité est signée de nos confrères de Skoden, portail de la FOAD (formation ouverte et à distance) de la Région Bretagne. Le répertoire offre la possibilité de découvrir des outils 2.0 existants en version française : de quoi ne pas rebuter les apprenants, animateurs, formateurs et enseignants qui éprouvent notamment des difficultés avec la langue de Shakespeare. Répertoire de services 2.0 gratuits pour une utilisation pédagogique Ce répertoire a été mis en ligne début septembre 2014 dans le cadre de la rentrée. Outils 2.0 en français (webographie des sites gratuits avec une interface en français) sera complété au fil des découvertes et des outils testés par la rédaction de Skoden.

Story of Stuff Case It Home Page - free molecular biology computer simulations simulation software Case It! is a National Science Foundation - sponsored project which provides a framework for collaborative case-based learning via free, open-ended molecular biology simulations and cases based primarily on genetic and infectious disease . Case It v6.06 * is a simulation that performs common laboratory procedures on any DNA or protein sequence. It has all of the capabilities of the earlier version (6.05), but adds new features such as SNP and expression microarrays. CaseItv6.06 must be used in conjunction with MEGA4 or MEGA5 ** to fully implement bioinformatics features. Case descriptions are in the Student version of the Resource Manual. Note : We are in the process of converting older tutorials to the new screencase video format.

Foldscope - The Origami Paper Microscope by Foldscope - Manu Prakash & Jim Cybulski The Foldscope, a portable and versatile microscope made mostly out of paper (water-proof), magnifies the wonders of the microscopic world, without the bulk and expense of a conventional research microscope. Foldscope is designed to bring microscopy out of science laboratories and into the hands of people around the world. Foldscope is a real microscope, with magnification and resolution sufficient for imaging live individual cells, cellular organelles, embryos, swimming bacteria and much more. Because the Foldscope is so affordable and can be used anywhere, it brings science to your daily life, whether that means looking at what's growing in your flower pot or watching bacteria from your mouth or analysing the bee stinger that got your thumb. Our goal is to encourage and enable the curious explorer in each of us and make science happen anywhere, anytime. (All the footage in the video below was collected in the field using a standard Foldscope with 140X lens, coupled to an iPhone). 1. 2.

What If All 7.1 Billion People Moved To Tunisia? I’ve always been interested in the distribution of the human population across the globe. It’s far from an even spread—this map shows where people are most squished in (dark colors) and where they’re spread out (light colors): And the East Asian countries in particular are so jam-packed with people that there’s this insane fact: (Parts of Malaysia and Indonesia have been intentionally left out—without them, the red regions still contain more than 50.2% of the world’s population.) To gain perspective on just how differently people are living on this planet, I looked up the average population density of a particular city, state, or country, and imagined all humans living at that density. (While we’re here—if all the habitable land on Earth were as dense as Manhattan, you could fit 1.73 trillion people on the planet.

How To Create Stunning Flowcharts With Microsoft Word Advertisement If man were a logical beast, math would be the easiest subject and love wouldn’t exist. Thankfully, when it comes to logic, the right tools can help simplify any process. Flowcharts are among those visual thinking tools that go grossly ignored for non-technical tasks. Again, it need not be a technical exercise. What Are Flowcharts? Frank Gilbreth, an engineer is believed to have created the first “Process Flow Charts” in 1921. As standard symbols illustrate the steps, it is easy to make out how it all fits together. Uses of Flowcharts The beauty of flowcharts lies in their simplicity. Once the flowchart has been illustrated, it is easy to take a birds-eye view and understand the whole process. Examine any process.Communicate steps to other people involved in a process.Organize a process by removing redundant steps.Identify and troubleshoot potential problems.Improve a process. A Basic Flowchart Flowcharts come in different shapes and sizes. Maximize your page area.
