Advancing Student Leader Development Through Student Organization Advising and Institutional Support

Abstract: This chapter explores the potential and promise of student organization advisors in facilitating student leader development. Through exploration of key aspects of institutional support, the author identifies ways that advisors of all backgrounds contribute to the teaching and learning experiences of students.

Regular Sampling on Metabelian Nilpotent Lie Groups: The Multiplicity-Free Case

Abstract: Let N be a simply connected, connected non-commutative nilpotent Lie group with Lie algebra \(\mathfrak{n}\) having rational structure constants. We assume that \(N = P \rtimes M,\) M is commutative, and for all \(\lambda \in \mathfrak{n}^{{\ast}}\) in general position the subalgebra \(\mathfrak{p} =\log (P)\) is a polarization ideal subordinated to λ (\(\mathfrak{p}\) is a maximal ideal satisfying \([\mathfrak{p},\mathfrak{p}] \subseteq \ker \lambda\) for all λ in general position and \(\mathfrak{p}\) is necessarily commutative.) Under these assumptions, we prove that there exists a discrete uniform subgroup Γ ⊂ N such that L2(N) admits band-limited spaces with respect to the group Fourier/Plancherel transform which are sampling spaces with respect to Γ. We also provide explicit sufficient conditions which are easily checked for the existence of sampling spaces. Sufficient conditions for sampling spaces which enjoy the interpolation property are also given. Our result bears a striking resemblance with the well-known Whittaker-Kotel’nikov-Shannon sampling theorem.

A kinematic analysis of the Thai boxing clinch

Abstract: The purpose of the study was to investigate the kinematics between the double collar-tie and double underhook Thai Boxing clinching positions. Ten amateur mixed martial arts athletes executed six knee strikes for both clinching positions with their dominant limb directed towards a target. A standard two-dimensional video motion analysis was conducted, and the results showed a statistical significant difference at the hip joint angle and the angular acceleration of the knee and ankle. Within both clinching positions, there was a statistically significant correlation between the hip and knee joint angles, hip and knee angular velocities, and hip angular acceleration. Between both clinching positions, there was a statistically significant correlation at the knee joint angle, knee angular velocity, and hip angular acceleration. This study demonstrates the importance of the hip and knee joint movements in both clinching positions, which implies the applications of strength training and flexibility at these joints for sports performance and injury prevention. It is suggested that future studies analyzing the non-dominant leg are warranted to fully understand the Thai Boxing clinch.

Incorporating NoSQL into a database course

Abstract: This article introduces the concepts of Big Data and NoSQL and describes a semester long web-based project that uses both a relational database (Oracle 11g) and a NoSQL (MongoDB) database for an undergraduate database course. The relational database stores the record information of an online sales system and the NoSQL database stores three manuals. The semester long assignment and its implementation are available as a download.

Mixing time and eigenvalues of the abelian sandpile Markov chain

Abstract: The abelian sandpile model defines a Markov chain whose states are integer-valued functions on the vertices of a simple connected graph G. By viewing this chain as a (nonreversible) random walk on an abelian group, we give a formula for its eigenvalues and eigenvectors in terms of ‘multiplicative harmonic functions’ on the vertices of G. We show that the spectral gap of the sandpile chain is within a constant factor of the length of the shortest noninteger vector in the dual Laplacian lattice, while the mixing time is at most a constant times the smoothing parameter of the Laplacian lattice. We find a surprising inverse relationship between the spectral gap of the sandpile chain and that of simple random walk on G: If the latter has a sufficiently large spectral gap, then the former has a small gap! In the case where G is the complete graph on n vertices, we show that the sandpile chain exhibits cutoff at time 1 4π2 n logn.
