Vector Partitions
Integer partitions have been studied by many mathematicians over hundreds of years. Many identities exist between integer partitions, such as Euler’s discovery that every number has the same amount of partitions into distinct parts as into odd parts. These identities can be proven using methods such as conjugation or generating functions. Over the years, mathematicians have worked to expand partition identities to vectors. In 1963, M. S. Cheema proved that every vector has the same number of partitions into distinct vectors as into vectors with at least one component odd. This parallels Euler’s result for integer partitions. The primary purpose of this paper is to use generating functions to prove other vector partition identities that parallel results of integer partitions
Controlling Air Traffic (Simulated) in the Presence of Automation (CATS PAu) 1995: A Study of Measurement Techniques for Situation Awareness in Air Traffic Control
As automated systems proliferate in aviation systems, human operators are taking on less and less of an active role in the jobs they once performed, often reducing what should be important jobs to tasks barely more complex than monitoring machines. When operators are forced into these roles, they risk slipping into hazardous states of awareness, which can lead to reduced skills, lack of vigilance, and the inability to react quickly and competently when there is a machine failure. Using Air Traffic Control (ATC) as a model, the present study developed tools for conducting tests focusing on levels of automation as they relate to situation awareness. Subjects participated in a two-and-a-half hour experiment that consisted of a training period followed by a simulation of air traffic control similar to the system presently used by the FAA, then an additional simulation employing automated assistance. Through an iterative design process utilizing numerous revisions and three experimental sessions, several measures for situational awareness in a simulated Air Traffic Control System were developed and are prepared for use in future experiments

The Frequency of Texting on Middle School Students\u27 Writing Achievement
The purpose of this correlational study was to discover the impact of texting on writing achievement for middle school students. The theory guiding this study is Vygotsky’s Social Cognitive Theory (Newman & Holzman, 2013) as it explains that learning is influenced by one’s social environment. The data that will be collected consists of the scores of the writing portion of the 2014-2015 state standardized test (ISTEP), a student survey answering questions about texting practices, and student status information on Free and Reduced Meals. The multiple regression analysis will be used to analyze this data because as inferential statistics it can be used to predict whether this information can apply to other future populations. Texting is a common practice and so is utilizing textspeak, (the digital language developed in order to make written communication on cellular devices more efficient). Middle school students represent the largest demographic of frequent texters, therefore one may assume this practice has the potential to influence daily writing habits throughout one’s lifetime. This study must be conducted in order to determine how textspeak is impacting the evolution of language and document the changes in language on education and the world as a whole. This quantitative, correlational study analyzes state standardized test, writing scores and the effects of frequent texting of middle school students. The middle school has a population of approximately 1500 students and the sample will be selected by meeting the following requirements: any sixth through eighth grader who has a personal cellular device and who has returned a parent consent form. This study seeks to answer the questions: Is there a relationship between frequency of texting and adolescent writing achievement? and Is there a difference in the impact of texting between adolescents eligible for Free and Reduced Meals and those adolescents who are not eligible
Aesthetics at Work: Using Principles of Art and Beauty to Improve Work Engagement
University of Minnesota Plan C final project. Spring 2014. Degree: Master of Liberal Studies. Advisers: Barbara Crosby, Julie Neraas. 1 digital file (pdf)Organizations today need employees who are creative and innovative, yet most OD and HRD initiatives focus only on technical learning. This project challenges the effectiveness of narrow, skills-based, and transactional design and implementation of employee training programs. The integration of aesthetics into HRD is proposed to improve training and development practices through the integration of imagination and creativity. The implications of aesthetics in HRD are outlined, including more holistic learning programs, improved work engagement, and a legitimate need for artful and art-inspired HRD
Examining Engineering Technology Students: How They Perceive and OrderTheir Thoughts
The lack of rigorous research focused on engineering technology students leaves administrators and practitioners in this area without adequate resources to advise and guide this unique population. This absence of research can most likely be attributed to smaller student populations as compared to other related fields, receiving attention, such as engineering. A preliminary systemic review reveals that research defining whom the engineering technology students are and how they think is largely unavailable. This study is expected to further improve our understanding of engineering technology students and how they change over time. Both freshman and senior engineering technology students were asked to complete the Gregorc Style Delineator. 1 This instrument allows the investigation of how these students perceive and order their thoughts within four defined areas of abstraction and logic referred to as mediation channels. Gregorc asserts that these channels of mediation facilitate how we relate to the world via a psychological style.2 Gregorc found that humans have comparable amounts of all the abilities assessed in the instrument. However, he does state that we are naturally predisposed to using two mediation channels. This predisposition of using two mediation channels provides differentiation between one person and another. Gregorc asserts that these differences can lead to conflict and misunderstandings.1 This study found that the mediation channels which are most often seen in engineering technology varies by gender. The findings of this study show that mediation channels vary among female students and are evenly distributed over all mediation channels, while male students are most often concrete in how they perceive and prefer sequential ordering of their thoughts. This may be attributed to the lower number of female students, due to this the recommendations focus on the instrument results for the male students. Also, these results suggest that practitioners should be designing classroom experiences that focus on students who are concrete/sequential and concrete/random styles, resulting in structured, predictable, and logical presentation of materials. Overall, these students prefer iterative solutions and use of intuition
Derived mapping spaces as models for localizations by Jennifer E. French.
Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Mathematics, 2010.Cataloged from PDF version of thesis.Includes bibliographical references (p. 71-73).This work focuses on a generalization of the models for rational homotopy theory developed by D. Sullivan and D. Quillen and p-adic homotopy developed by M. Mandell to K(1)-local homotopy theory. The work is divided into two parts. The first part is a reflection on M. Mandell's model for p-adic homotopy theory. Reformulating M. Mandell's result in terms of an adjunction between p-complete, nilpotent spaces of finite type and a subcategory of commutative HIF,-algebras, the main theorem shows that the unit of this adjunction induces an isomorphism between the unstable HF, Adams spectral sequence and the HIF, Goerss-Hopkins spectral sequence. The second part generalizes M. Mandell's model for p-adic homotopy theory to give a model for K(1)-localization. The main theorem gives a model for the K(1)- localization of an infinite loop space as a certain derived mapping space of K(1)- local ring spectra. This result is proven by analyzing a more general functor from finite spectra to a mapping space of K -algebras using homotopy calculus, and then taking the continuous homotopy fixed points with respect to the prime to p Adams operations.Ph.D
