1 Does obesity lead to poor school performance? Estimates from propensity score matching Hongyun Han Department of Sociology‚ University of Wisconsin-Madison March 26‚ 2012 ABSTRACT High body weight is negatively associated with test scores among elementary and middle school students. Are these negative outcomes due to preexisting differences‚ or are they a casual effect of childhood obesity? To better understand the causal mechanisms underlying this pattern‚ I use a propensity score matching

equiconvex lens (made from a glass of known refractive index) and an adjustable object needle APPARATUS: A convex lens‚ an optical needle‚ a plane mirror‚ a clamp stand‚ a spherometer‚ a plumb line‚ metre scale‚ water and turpentine oil Theroy : Let’s add small amount of water on a flat‚ plane surface and place a convex lens over it. This forms a plano-concave lens of water between the lower surface of convex lens and plane mirror. Let f 1 and f 2 are the focal lengths of water lens and convex lens respectively

Refraction in Biconcave Lens Now let’s investigate the refraction of light by double concave lens. Suppose that several rays of light approach the lens; and suppose that these rays of light are travelling parallel to the principal axis. Upon reaching the front face of the lens‚ each ray of light will refract towards the normal to the surface. At this boundary‚ the light ray is passing from air into a more dense medium (usually plastic or glass). Since the light ray is passing from a medium in

Readings: How ethical are you? Four types of bias * Implicit prejudice(bias that favours majority) bias that emerges from unconscious beliefs‚ because people tend to associate things that commonly go together and expect them to inevitably coexist (thunder and rain). Implicit prejudice arises from the ordinary and unconscious tendency to make associations‚ but this is not conscious forms of prejudice‚ such as overt racism/ this is problem is inherent * In-group favoritismbias that favours

Song Representation of Antigone The song I chose to represent Creon is Pray by Sunny Hill. The song pray fits Creon because in several lines of lyrics fit regret and guilt of what Creon had done. A couple of the lines from the song related to Creon asking for Tiresias help but then not liking the answer‚ for example "Someone told me to pray to dream‚ that it will come true no matter what it is. Tell me everything- look at me and tell me‚ tell me to please stop." Inside Creon knew Tiresias was right

the Thin-Lens Equation: Where f is the focal length of the lens‚ do is the object distance and di is the image distance. From the Thin-Lens Equation we are able to mathematically see and understand many interesting and valuable situations that arise when working with lenses. When the object is the same distance from the lens as the image‚ for instance‚ we can easily verify that the focal length must equal half the image (object) distance or if the object is very far away from the lens (at infinity)

due to not being properly educated‚ Chinese are the worst drivers in the world- “he was convinced this was so because of the shape of their eyes‚ as far as he could surmise‚ it denied them peripheral vision.” (Bissoondath‚ Pg. 75) To have complete bias free thinking versus preconceived notions regarding other cultures is more difficult than you think.
