Painter’s historical interpretation managed to grab a lot of attention to reconsider America’s virtue and vice in the Progressive Era. Nell Irvin Painter’s 1987 historical monograph, Standing at Armageddon The United States, 1877-1919, focused on the lives of many citizens concerned with positive characteristics of America. Nell began the monograph with an introduction with a sense of fear to readers by asking if the end is near. This might infer that people were standing near a place of…

4.6 Model building for monthly temperature series According to Takele (2012), the process of model fitting involves data plotting, data transformation if necessary, identification of dependence order, estimation of parameter, diagnostic analysis and choosing appropriate model. In this section, a univariate SARIMA methodology is used to model maximum and minimum monthly temperatures of Nairobi. 4.7 Model Identification ACF and PACF plots are used in the identification of the values p, q, P and…

form of transportation is more than the normal household can use. Therefore this requires that the existing power grid is needed to upgrade most of the facilities in the in the grid. This includes the generation, the transmission network, and the distribution systems. This, therefore, requires that massive investment be put in place to provide the required amount of power to the transportation system. Nevertheless, the power grid system may achieve a relief if the transport system is installed…

America prides itself on being a democratic government and a land of equal opportunity, but does it live up to those standards? Incoming inequality is growing in American society, and the effectiveness of democracy is being threatened by this increasing inequality. While America has claimed to make strides toward racial and gender inequality there is a growing gap between the haves and have nots. This income gap is increasing rapidly between the rich and the middle class and the middle class is…

significant increase in longleaf pines, (Pinus Palustris) and a decrease in woody species, compared to the unburned area. In fact, it jumped from a frequency of 15 in the unburned area to a frequency of 50; which is two times that of the burned area (see figure 1). Compared to all other species of tree, Pinus Palustris experienced the most increase of frequency. Whereas, Pinus Clausa or sand pine, was only present in the burned area showing that it was a successional species. All other species…

who face the daily hypocrisy of our modern system of income ‘equality’. The fact that the middle class once enjoyed the equal distribution of wealth is now almost nonexistent. As the years have gone by, the level of income inequality has increased and so has the poverty. There is no equality for those who make up most of the middle class. Not only that, but the distribution of wealth today making the rich, richer and the poor, poorer. That’s where justice isn’t justice anymore when money is the…

states, but also within states among different classes. First, this paper will examine inequality within state borders. The Gini coefficient is a tool used to measure the income distribution within the country. A Gini coefficient of 0 means equal distribution of income, while a Gini coefficient of 1 is the most unequal distribution. When the income data is examined in quintiles, one will see inequality rising. The interesting factor being income inequality within states has mainly risen in…

be a prosperous country in many aspects, especially in terms of wealth. In fact, as of 2016, France was ranked as one of the top wealthiest countries in the world. Although France has been viewed as a wealthy country, there is inequality in the distribution of wealth amongst its people. As a result, this often causes a sense of alienation and differentiation between people of different economic standing. This segregation and Othering between the wealthy and the poor has been very prominent in…

Quality is a perceptual, conditional, and somewhat subjective attribute and may be understood Sigma is a Greek term .It is used in statistics to represent standard deviation from mean value, an indicator of the degree of variation in a set of a…

The article, “Standard Error of Measurement” by Leo M. Harvill from East Tennessee State University, provided a general introduction of Standard Error of Measurement (SEM). First, it introduced the basic concepts of test reliability. An obtained score or a raw score refers to the number of points obtained by an examinee. The obtained score could be influenced by several factors such as the ambiguity of test items, the fatigue of the examinee, and these factors make the obtained score unlikely to…
