POSITION PAPER: US westward expansion pre 1877

Land purchases and treaties with the Natives gave the white Europeans some amount of legal rights to occupy the land, but were often attained through fraud and warfare. The resistance that met the move West was confronted by violence and the forceful movement of the Natives off... Westward...

Philosophy final paper pre-question
...Great Works of Western Philosophy Aristotle’s notion of function Aristotle composed Nichomachean Ethics in order to discover the human good towards which we should aim in life. Aristotle refers to this conception of ‘good’ with various connotations such as happiness, well-being, flourishing and so on. However, there is a considerable amount of variation in how people conceive of the term ‘happiness’. Aristotle suggests that in order to come to a clearer and distinct conception of happiness, it is first important to ascertain the function of a human being. Aristotle precisely states that “for all things that have a function or activity, the good and the ‘well’ is thought to reside in the function.” Therefore, it is the human good... Works of...

...User Satisfaction and Its Implications to CPOE Implementation: The Case of Two Community Hospitals in Westchester, New York The race for full implementation of Computerized Physician Order Entry (CPOE) system is underway, but health care organizations are still at a loss on how they can meet meaningful use requirements when their own employees are resisting the change. There are many reasons cited for such resistance. A study published by the Journal of the American Medical Association (Koppel et al., 2005) highlighted that CPOEs actually facilitated as many as 22 types of medical errors instead of enhancing patient safety in its area of research. Other issues concerning CPOE use have also surfaced in various studies. For example... Satisfacti...

Pre lab springs
...Springs and Oscillators From the theory section of the lab we have two ways to determine the angular frequency ɷ of oscillations of the mass m: ɷ=2π∕ T and ɷ=√kd/m+mo a. Both ways to determine angular frequency ɷ must give the same value. Equate the above equations and solve for T2. ɷ=√kd/m+mo Kd is the spring constant between the initial stretch and the final stretch (x-xo) K varies with the level of stretch of the spring, thus, Kd=δF/δx F=mg 200g*9.8 0.2*9.8=1.96N Let the stretch be from 0 cm to 10 cm making the stretch, x=10cm=0.1m Kd=1.96N/0.1m =19.6N/m Considering the range of masses from 200g to 600g, m+mo=200+600 800g=0.8kg Thus, Kd/m+mo= 19.6/0.8=24.5 ɷ=√24.5=4.95 ɷ=2π/T But ɷ=4.95, thus, 4.95=2π/T 4.95T=2π T=...

...Preparation of Cyclohexene from Cyclohexanol using exothermic reactions Lab 9 Chemistry Paper [Department] Cyclohexanol, an alcohol, mixes with acids such as sulfuric acid and phosphoric acid to undergo elimination of El. This involves a unimolecular two-step process of conversion through mechanism cyclohexene. The product of end result structure after experimentation usual confirmation is through Refractive Index, FTIR, and HNMR analysis. Introduction Cyclohexanol is a secondary alcohol that undergoes dehydration by an E1 mechanism. This molecule is related to cyclohexane with replacement of one hydrogen atom of a hydroxyl group. The major intermediate of this mechanism is a cyclohexyl cation, which can undergo both substitution...
