Using Common Academic Indicators to Predict Graduation Rates at CSUN, 2005-2014
Get PDFThe median time to graduation at California State University, Northridge (CSUN) is five years and fewer than fifty percent of first time freshmen graduate in less than eight years. We used data mining and predictive analytics to determine some of the key academic indicators of success at CSUN. The most important indicators that we found were (a) which math course the student was placed in (or took first); (b) student grade point average (GPA) at the end of each of the first two terms in residence; and (c) successful completion of a freshman experience seminar course (UNIV 100). When all three are considered simultaneously, we can correctly identify over two thirds of the students who will drop out without graduating, while misidentifying approximately one-fifth of students who ultimately graduate as at-risk of not graduating
Discrete Approximation of Coloring the Plane
Get PDF This work is inspired by the open problem The Chromatic Number of The Plane. We approximate the plane by only considering points with coordinates (p/n, q/n), where p and q are integers, and n is a fixed positive integer. To prevent triviality, we add the restriction that two points are adjacent if and only if their distance is between 1-ε and 1+ε for a non-negative ε. Adjacent points have to be colored differently. Our goal is to find the smallest ε for each n that will force us to use five colors
Comparisons of Measured Body Composition and Self-Perception of Body Type In Racially and Ethnically Diverse Male and Female College Students
Get PDFIndividual perception of body size varies by gender and ethnicity and some these groups have been found more accepting of overweight body types than others. Groups who positively value body types deemed clinically overweight or obese may be unreceptive to weight management techniques aimed to decrease risk for obesity-related chronic diseases. The present study examined the relationship between perceived body image and measured body composition, across race and gender, in a group of 240 college-aged students. Participants underwent skinfold body composition assessment and completed a questionnaire designed to elicit perceptions of body image and body weight status. One in four females who were in the acceptable range for body fat percentage identified themselves as overweight. Over half of White males (57%), White females (80%), and Black females (50%), who were overweight, perceived themselves to be “about the right weight”. Over half of all Asian (56%), Black (50%), and Hispanic (67%) males, in the acceptable range for body fat percentage identified themselves as overweight. These findings indicate a majority of individuals, regardless of gender, race, or ethnicity misperceive their body type and consequently may be unaware of the potentially negative affect on their overall health status
Decolonizing Leadership Practices: Towards Equity and Justice at Hispanic-Serving Institutions (HSIs) and Emerging HSIs (eHSIs
Get PDFHispanic-Serving Institutions (HSIs; colleges and universities that enroll at least 25% Raza undergraduates) are increasing in number in the United States, growing rapidly from 189 in 1994 to 492 in 2016. Moreover, there were 333 emerging HSIs (eHSIs) in 2016, indicating that the number of HSIs will continue to grow; however, leaders, including faculty, staff, and administrators at (e)HSIs, continue to grapple with the question, “How do we move from ‘enrolling’ to ‘serving’ Raza students?” There are a lack of leadership frameworks specifically designed for those working at (e)HSIs and with a focus on serving Raza students. The authors argue that decolonizing leadership practices will help leaders liberate and empower Raza students by disrupting the coloniality of power that promotes and sustains higher education institutions as racial/colonial projects. The authors propose leadership processes for working with Raza students at (e)HSIs. Although leaders at non-(e)HSIs may consider these processes, the authors call on leaders at (e)HSIs to transform their leadership practices as a necessity for becoming Raza-serving
Dilated Floor Functions That Commute Sometimes
Get PDFWe explore the dilated floor function fa(x)= ⌊ax⌋ and its commutativity with functions of the same form. A previous paper found all a and b such that fa and fb commute for all real x. In this paper, we determine all x for which the functions commute for a particular choice of a and b. We calculate the proportion of the number line on which the functions commute. We determine bounds for how far away the functions can get from commuting. We solve this fully for integer a, b and partially for real a, b
Straightening Identities in the Onsager Algebra
Get PDFThe purpose of this work is to formulate and prove some straightening identities in the Onsager algebra. Our identities allow one to rewrite specific products of basis elements as linear combinations of products which are in a different order. Such identities could be helpful in understanding the representation theory of the Onsager algebra
¡Revolución Sin Fronteras! Mexican Immigrants, Mexican-Americans, and Magonistas in Los Angeles, 1900-1930
Get PDFFrom the 1900s to the 1930s, the Anglo power structure in Los Angles silenced all groups who challenged their rule. Ricardo Flores Magón, who was the intellectual writer for the Mexican Revolution in the early 20th century, resisted the Mexican dictator Porfirio Diaz and the Anglo rule in Los Angles. This paper argues that the Anglo power system targeted Magonistas, followers of Ricardo Flores Magón, Mexican immigrant workers, and Mexican Americans during the Mexican Revolution to prevent an uprising in Los Angeles and to maintain close economic ties with Porfirio Diaz and Mexican elites in general. To prove my thesis, I utilized the Archivo Digital de Ricardo Flores Magón. This online archive contains Ricardo Flores Magón’s newspapers Regeneración and Revolucion. I also utilized the Los Angeles Times Historic. This online archive contains all newspaper articles published by the Los Angeles Times. I used the two newspapers to compare the Magonista and Anglo perspectives. The third online archive I used was the Strachwitz Frontera Collection which contains music written by Mexican and Mexican Americans. The final online primary source collection that I referenced was the Anarchist Library. This online collection contains various documents written by anarchists; including the works written by Ricardo Flores Magón. Using the four primary source collections will support my thesis
