Knowing the difference between a weed in the backyard and the weed used to intoxicate is becoming increasingly rare (Nature Deficit Disorder Takes Root) as children of the post-millennial years are becoming more disconnected with nature. Nature Deficit Disorder, NDD, was termed in 2005 by researcher and author, Robert Louv in his book, Last Child in the Woods. It is used to describe the nature void people have in their life. NDD isn’t an official medical term but there are significant effects it…

This write-up focusses on three concepts of sound assessment practice namely reliability, feasibility and educational impact. Reliability Reliability refers to the ‘reproducibility’, ‘repeatability’ or ‘consistency’ of the scores obtained from an assessment (Memon et al, 2010; van der Vleuten et al, 2005). Reliability is generally expressed as a coefficient ranging from 0 (no reliability) to 1 (perfect reliability). Since it is difficult to achieve perfect reliability in any assessment, a…

neutral because scientists have that desire to want something that will describe the natural world. Scientist first come up with a hypothesis, which is supposed to be objective but since labs are carried out to find a particular thing, the hypothesis can not be objective. Scientist use intuition from observations or other events to develop a hypothesis and in doing so they are carrying bias in their hypothesis. An example of subjectivity in the natural sciences are when scientists want to find…

INTRODUCTION: Many processes in the world can be studied and analyzed; everything is a process in one way or another. One system that might not be considered a “process” at first glance, but which operates as one, is the education system. If you consider graduation rates, literacy rates, and the general intelligence of an educated populace as the variables being tested, one could determine if the education system is in control or reliable. We originally wanted to perform this study to compare…

Retrieved January 31, 2017. The basic concept that is being explored are about enzymes. Enzymes are proteins that are known for being sparkplugs in a chemical reaction. Enzymes have a shape and for them to ‘spark’ they must have the proper substrate for it to work U. This does not change the enzyme’s…

to the work of tow scholars, Von Rad and Noth. Though Noth holds that there is another source which influences J’s writings, Von Rad claim cannot be ignored that it is “J who creates the “history of salvation” that begins with the creation of the world and end with entry of Israel into Canaan” (1014). It would appear that the J sources provides the most practical and common explanation as to the origins of man and ultimately Israel’s role as the people of…

We can use BT with the invading UFOs. What’s the chance that an abducting UFO is from Zargon? (What is the chance that a UFO is from Zargon given that it abducts?) P(Zargon|Abduct) = P(Abduct|Zargon) x P(Zargon) P(Abduct) P(Zargon|Abduct) = 3 /8 x 8 /20 = 24/160 = 1 /2 6 /20 6 /20 This is the answer we’ve already seen. iv. -AT LEAST ONEWe flip three coins. What is the chance that any (at least one) of them lands Heads? We could solve this problem the way we’ve already done: count the outcomes…

Introduction: Bacteria are very diverse and are part of the prokaryotic domain. Some bacteria can be harmful, but others can also be beneficial in many ways. There are bacteria everywhere on Earth; places that you would think would have bacteria, like your gastrointestinal tract or our skin (Wenner, 2007). Although bacteria are small in size and are a simple cell organism, it is essential to life. There are different ways in how to distinguish and classify bacteria. One way is you can look…

PCR is a common practice used to amplify a certain region of DNA. In this experiment, PCR was used to amplify the 16S ribosomal RNA gene of the bacteria. This locus was used because it is one that evolves slowly in bacteria. A Taq polymerase is used for this PCR because of the temperatures the reaction goes through. The16S rRNA primers used in this PCR, are complimentary to sequences…

dependent variable is the subjects Calorie/menu choices. The researcher has posed three Research Question, and has identified a null and alternative hypothesis for each. RQ1: Are young Millennials’ menu choices on low-Calories items correlated with different menu designs applying menu psychology? Tian has created a null hypothesis and alternate hypothesis for each factor studied when considering the menu design to include the serial position effect, the gaze motion theory and the salience…
