Tunable Transient Decay Times in Nonlinear Systems: Application to Magnetic Precession
The dynamical motion of the magnetization plays a key role in the properties
of magnetic materials. If the magnetization is initially away from the
equilibrium direction in a magnetic nanoparticle, it will precess at a natural
frequency and, with some damping present, will decay to the equilibrium
position in a short lifetime. Here we investigate a simple but important
situation where a magnetic nanoparticle is driven non-resonantly by an
oscillating magnetic field, not at the natural frequency. We find a surprising
result that the lifetime of the transient motion is strongly tunable, by
factors of over 10,000, by varying the amplitude of the driving field.Comment: EPL Preprin
Societal psychology in Norway
This special issue is comprised of a diverse collection of theoretical and empirical papers from Norway. The choice of societal psychology as a means of organizing these contributions will be discussed in this introduction. Although the term is infrequently used internationally, it has been adopted as the closest translation for the Norwegian disciplinary boundary samfunnspsykologi, which has structured each main contributor’s experience of psychology as graduate or post-‐graduate researchers. I also hope to illustrate that Himmelweit’s (1990) original conceptualization of societal psychology is also appropriate to unify these articles due to its openness toward multiple theoretical and methodological perspectives
In vivo imaging of pyrrole-imidazole polyamides with positron emission tomography
The biodistribution profiles in mice of two pyrrole-imidazole polyamides were determined by PET. Pyrrole-imidazole polyamides are a class of small molecules that can be programmed to bind a broad repertoire of DNA sequences, disrupt transcription factor-DNA interfaces, and modulate gene expression pathways in cell culture experiments. The 18F-radiolabeled polyamides were prepared by oxime ligation between 4-[18F]-fluorobenzaldehyde and a hydroxylamine moiety at the polyamide C terminus. Small animal PET imaging of radiolabeled polyamides administered to mice revealed distinct differences in the biodistribution of a 5-ring β-linked polyamide versus an 8-ring hairpin, which exhibited better overall bioavailability. In vivo imaging of pyrrole-imidazole polyamides by PET is a minimum first step toward the translation of polyamide-based gene regulation from cell culture to small animal studies
A Sensitive Faraday Rotation Setup Using Triple Modulation
The utilization of polarized targets in scattering experiments has become a
common practice in many major accelerator laboratories. Noble gases are
especially suitable for such applications, since they can be easily
hyper-polarized using spin exchange or metastable pumping techniques. Polarized
helium-3 is a very popular target because it often serves as an effective
polarized neutron due to its simple nuclear structure. A favorite cell material
to generate and store polarized helium-3 is GE-180, a relatively dense
aluminosilicate glass. In this paper, we present a Faraday rotation method,
using a new triple modulation technique, where the measurement of the Verdet
constants of SF57 flint glass, pyrex glass, and air were tested. The
sensitivity obtained shows that this technique may be implemented in future
cell wall characterization and thickness measurements. We also discuss the
first ever extraction of the Verdet constant of GE-180 glass for four
wavelength values of 632 nm, 773 nm, 1500 nm, and 1547 nm, whereupon the
expected 1/{\lambda}^{2} dependence was observed.Comment: 4 pages, 2 figures Updated version for RSI submissio
INCREASING ATTENDANCE OF EWU STUDENTS AT CHENEY MAYFEST: DOES SOCIAL MEDIA PLAY A ROLE?
The non-profit organization, Cheney Mayfest, puts on an event each year to promote the community and its local businesses. Most of the Cheney community is Eastern Washington University (EWU) students. Cheney Mayfest’s goal is to have an increase in EWU student attendance at Mayfest each year. In order to examine the best way to reach them, this study examines what motivates EWU students to attend and the barriers as to why they do not attend. Findings from this study indicate that most students do not know what Cheney Mayfest is and have not seen any marketing for the event. Understanding the different motivations and barriers for why they do not attend could help find a way to enhance the attendance of EWU students at Mayfest. This thesis seeks to identify why there is a low attendance of EWU students and whether a social media marketing plan can play a role in enhancing student attendance

Managing the Brand: Administrative Structure of the Hidden Profession of Collegiate Trademark Licensing
This study analyzes the current state of collegiate trademark licensing departments through first-hand accounts from current or past licensing professionals. Semi-structured interviews were conducted to understand current issues that are facing the licensing industry, particularly focusing on internal organizational structure of collegiate trademark licensing departments at institutes of higher education. Eleven participants, including licensing agents, licensees, licensing directors, and licensing experts were interviewed and the following themes emerged. Trademark licensing is a hidden profession, with little education available about the industry. Programs have greatly evolved over recent decades, but institutional infrastructure still lags in the appropriate assets and resources to sustain a growing program. Licensing directors have strong professional relationships with others in the field, but often have difficulty receiving buy-in to licensing objectives from their internal peers. A strong sense of ‘university’ versus ‘athletics’ exists, causing confusion and discrepancy in managing the multi-faceted licensing objectives
Calling Off the Bounty Hunters: Discrediting the Use of Alleged Anti-Kickback Violations to Support Civil False Claims Actions
As skyrocketing health care costs threaten the survival of federally funded health care programs, government prosecutors and private parties are frequently turning to the Civil False Claims Act\u27 as their weapon of choice in waging the war on health care fraud and abuse. The False Claims Act is a powerful federal statute that creates liability for the submission of false claims to the federal government. In the health care industry, a typical false claims plaintiff asserts that a health care provider submitted a Medicare or Medicaid claim to the federal government which was false because the provider mischarged or overcharged the government. In these cases, the provider seeks to defraud the government by submitting false assertions or false data.
Recent revisions of the False Claims Act, however, have encouraged prosecutors and private parties to apply the Act to the health care sector in new and creative ways. One of these innovations is the tainted claim. The tainted claim theory of False Claims Act liability asserts that a violation of a separate federal statute taints, or makes false, claims subsequently filed with the government. In the health care arena, well-publicized tainted claims have involved allegations that a violation of the Medicare/Medicaid anti-kickback statute tainted a subsequently filed claim for Medicare or Medicaid re- imbursement. This Note refers to these claims as anti-kickback- based tainted claims. Under this new theory of liability, the initial anti-kickback violation renders a subsequent Medicare claim false no matter how medically necessary and competently administered the services were, or how bona fide the claim for payment actually is. Thus, the alleged violation of the anti-kickback statute makes a claim false not because the claim is incorrect, falsified, or misleading, but because the provider violated a separate federal law.
The first purpose of this Note is to highlight the existence of anti-kickback-based tainted claims and outline their development. Accordingly, Part II of this Note gives a brief summary of the False Claims Act and its qui tam provisions which allow private citizens to bring false claims actions on behalf of the government. Part III provides a similar overview of the Medicare/Medicaid anti-kickbac
