Theme: Biodiversity: Eco-Math link through Linear Algebra A Brief Introduction Biodiversity and the Hudson River Flowing from the Lake Tear of the Clouds, North the Hudson River journeys 315 miles and drops 4,322 feet in elevation before emptying itself into New York Harbor. The Hudson River is home to diverse populations of fish, birds, and mammals that cohabit and compete among themselves for resources. Recently the American shad, Atlantic sturgeon, river herring (blue back herring and alewife), American eel, and largemouth bass are in decline. Intense economic harvesting pressure and overexploitation cause coastal and marine species to decline. Therefore, harvesting and fishing should be managed properly and carefully to avoid decline of current population. Food web analysis provides important information regarding the nature of competition among various organisms. Cluster analysis in graph theory is a popular method to seek partition of a given data set into several clusters so that the data points within the same cluster are more similar than those belonged in the separate clusters. In this project we will use cluster analysis using the concepts of linear algebra to study the competition among various species in a given food web, in particular, competition among various Hudson River species. Students will find a partition of the competition graphs based on the Hudson River food web such that the strength of competition (for shared preys) between two clusters (two groups of predators) is as low as possible; however, the strength of competition within the same clusters is as high as possible. Big Idea behind this project Study and analyze Hudson River Food Web and its competition graph to interpret the strength of species competition. Particularly we will be exploring the followings: • Which predator species are more connected than others? • What happens if a specific species (particularly, a prey) dies out? Particularly, how does the removal of a particular species affect its predators and also the overall competition among all predator species? I Students Learning Outcomes 1. To solve systems of linear equations using matrices. 2. To identify and use vector properties (spaces, subspaces, bases, inner product). 3. To identify properties of matrices (inevitability, eigenvalues, eigenvectors). 4. To use computer technology to solve problems. 5. To learn how to apply core mathematical concepts (particularly eigenvalues and eigenvectors) in solving real-world problems. 7. To understand interdisciplinary approach and the significance of it in real-world applications. General Education Learning Goals 1. To understand interdisciplinary approach and the significance of it in real-world applications. 2. To address a problem and resolve the problem with scientific methods.

PSY3405 Health Psychology, Spring 2015

PSY3405 Health Psychology, Spring 2015

This course provides an overview of existing psychological and epidemiological findings on the relationship between behavior and disease. The course explores how behavior, emotion and cognition can influence disease processes and examines the impact of stress and personal control on specific coronary, immune and infectious disease symptoms. Social support, referral and interventions for optimal physical and mental health are introduced. The interdisciplinary theme of this course will provide an overview of extant literature on theories of health psychology and behavior change within the context of critical race theory for a gained understanding of varied philosophies of science.

2013 Fall – MAT 2070 Proofs and Logic – Reitz

2013 Fall – MAT 2070 Proofs and Logic – Reitz

This course is designed to prepare students for an advanced mathematics curriculum by providing a transition from Calculus to abstract mathematics. The course focuses on the processes of mathematical reasoning, argument, and discovery. Topics include propositional and first order logic, learning proofs through puzzles and games, axiomatic approach to group theory, number theory, and set theory, abstract properties of relations and functions, elementary graph theory, sets of different cardinalities, and the construction and properties of real numbers.
