NOAH What is Self Fulfilling Prophecy and how does it affect educational outcome? INTRODUCTION Robert K. Merton (1910 – 2003) Professor of sociology invented the word self fulfilling prophecy to help make tangible and popular the idea that some pronouncement or statement positive or negative can alter peoples action to bring about fulfillment of same pronouncement

Crime has been a part of society since the very beginning. There cannot be rules without people who will break them. The question is‚ why do people commit crimes? Why do they steal‚ rape‚ and murder? There are many suggestions as to why people commit crimes‚ especially in impoverished areas. One of the more common and sensible explanations for this phenomenon is that of Merton’s Strain Theory. Merton’s strain theory is fairly straightforward in its application. It explores the idea that many people

Solution Focused Therapy for Children Rhonda Kendrick December 11‚ 2014 Solution-focused therapy has a unique orientation toward non-problem times. The purpose is to help people target and amplify resources and strengths toward change (Berg‚ 1994). The article that I researched is about a study of using the framework of solution focused therapy with children. Children were referred by the study for presenting problems involved those relating to “behavior‚” such as aggression toward

specific solutes to and from the cell. This implies that the membrane to most cells is selectively permeable or has a differential permeability to different solutes. Both the internal and the external environment to the cell are composed an aqueous solution that is made of dissolved organic and inorganic substances. The gradual or spontaneous movement of these substances in and out the cell are guided by a mechanism called diffusion. This is a movement by molecules to a region of lower concentration

two different solutions. Osmosis has a lot to do with this experiment and is the movement of water molecules from a higher concentration to a lower concentration. Osmosis only deals with water and is a type of diffusion. The difference between all three solutions is that in a hypertonic solution the cells fluid rushes out of the cell and causes it to shrivel. In a hypotonic solution water rushes into the cell and causes the cell to expand and eventually pop. In a isotonic solution water rushes in

however‚ deals solely with water. Osmotic pressure is the pressure of a solution against a semi-permeable membrane to prevent water from flowing into the membrane. In this lab‚ we are going to study tonicity; tonicity is the measure of this osmotic pressure and is the differential of pressure between two solutions separated by a selective membrane. To help identify the relative concentrations of solute particles of different solutions‚ we must understand that there are three possible differences in concentrations

permeable membrane. The aim of the experiment is to investigate the effect the salinity of solutions has on the process of osmosis and net weight gain/ loss by potato cells. This would be done by using similar size potato cubes and covering them with different concentrations of saline solutions (0.5% and 2.0%) in beakers then measuring the change in weight of the potato cubes. If the salinity of the solution is high then the weight of the potato cubes will decrease. Materials • 9 X 2cm2 potato cubes
