W5D 590 Colin Powell - Essay Example Powell, the role of the leader is to create the most suitable environment for the followers and let everyone to contribute the common business goal with all their best (Karissa, 2013). To best bring the leader’s view about the organizational goal can be done through collaboration, an effective part of which is communication that creates unity without consensus. Here loyalty means to give one’s honest opinion and if the decision is been made, give no chances for the debate (Johnson, et al., 2008). The importance of truth-telling and safety where people are able to tell the truth create the atmosphere of unity and lead to the high performance of the corporate culture. Another view on how leader sees meeting of organizational goals is through creating a winning team (Schawbel, 2012), which is able to give business everything it needs. Here people should be trained in order to get connected to the common strategy, and have certain equipment to achieve the goals. There is al so philosophy of leadership which Powell shared with hundreds of business students. The central consideration about leadership is about getting people to make the most out of them, which is possible by creating conditions of trust, absence of fear or anger and constant presence of optimism. He also states (Stanford GSB Staff, 2005) that effective leaders are not born; instead they are capable to learn from their experience. Johnson, et al., (2008).

Investigation of the beer - Lambert law Lab Report

Investigation of the beer - Lambert law - Lab Report Example It illustrated in the diagram below. Beer-Lambert law states that the absorbance is directly proportional to the concentration of the solution. It relates the absorbance of sample (A) to the concentration of the substance in the solution absorbing it and the path length of the light. Incident light from a tungsten or deuterium lamp is focused through a lens and passed through a slit. Passing the beam through the wavelength selector diffracts it separating it into light of a single wavelength. This particular wavelength is selected and exits through the slit. The light passing through the sample is detected by the photo detector which then converts it into an electrical current measured by the galvanometer. The reading is then sent to a read-out device. The plot of absorbance of light at different wavelengths is called it absorption spectrum. Fig. 1 gives the absorption spectrum of potassium permanganate (KMnO4 ). According to Beer-Lambert law, absorbance is directly proportional to concentration. This is clearly illustrated by Fig. 4. This is also known as a calibration curve. It should be drawn with utmost accuracy in order to obtain a straight line graph. The slope of this curve is equal to the absorbance of the potassium permanganate (Skoog, 45). One source of error is the use of inappropriate concentrations when applying Beer-Lambert law. It is only applicable for dilute solutions and becomes less accurate with increase in concentration. Another source of error is stray light or scattering within the instrument as this cause large errors especially when reading small values. The aim of the experiment was obtained because Beer-Lambert law was verified. Using linear regression analysis, Beer-Lambert law (A = ÃŽ µlc) implies that when concentration is equal to zero, absorbance must also be zero. This is a straight line equation passing through the origin hence the aim was achieved (Svanberg,
