Development of an Education Module on Conflict Resolution for Charge Nurses

A healthy work environment is essential for providing safe and efficient care for patients. When nurses avoid conflict on a patient care unit they create an unhealthy work environment by leaving problems unresolved. Avoiding conflict is common due to the perception that conflict is a negative outcome of dysfunctional relationships. In reality, conflict is a normal part of human interactions that stimulates individuals to adapt to the diversity that surrounds them. Increasing charge nurses‟ understanding of interpersonal conflict and improving their skills of constructive conflict resolution, supports the creation and maintaining of a healthy work environment. An education module titled Embracing Conflict: A Bridge to a Healthy Work Environment is offered as a component of an interactive learning lab for charge nurse orientation. The concepts mutuality, pattern of the whole, and expanding consciousness from Margaret Newman‟s Theory of Health as Expanding Consciousness provides a theoretical framework for the module‟s development. As charge nurses model the skills of addressing and resolving conflict, they will increase the likelihood that others will recognize the benefits of constructively resolved conflict and modify their own response. Direct observation of participants practicing conflict resolution skills along with questions from and employee satisfaction survey are used to assess for immediate and long-term changes in behavior

Nonadiabatic quantum control of a semiconductor charge qubit

We demonstrate multipulse quantum control of a single electron charge qubit. The qubit is manipulated by applying nonadiabatic voltage pulses to a surface depletion gate and readout is achieved using a quantum point contact charge sensor. We observe Ramsey fringes in the excited state occupation in response to a pi/2 - pi/2 pulse sequence and extract T2* ~ 60 ps away from the charge degeneracy point. Simulations suggest these results may be extended to implement a charge-echo by reducing the interdot tunnel coupling and pulse rise time, thereby increasing the nonadiabaticity of the pulses.Comment: Related papers at http://pettagroup.princeton.ed

Variety of idempotents in nonassociative algebras

In this paper, we study the variety of all nonassociative (NA) algebras from the idempotent point of view. We are interested, in particular, in the spectral properties of idempotents when algebra is generic, i.e. idempotents are in general position. Our main result states that in this case, there exist at least $n-1$ nontrivial obstructions (syzygies) on the Peirce spectrum of a generic NA algebra of dimension $n$. We also discuss the exceptionality of the eigenvalue $\lambda=\frac12$ which appears in the spectrum of idempotents in many classical examples of NA algebras and characterize its extremal properties in metrised algebras.Comment: 27 pages, 1 figure, submitte

The potential of polymeric film-forming systems as sustained delivery platforms for topical drugs

Introduction: Dosing regimens requiring multiple daily applications frequently result in poor patient compliance, especially in the treatment of chronic skin diseases. Consequently, development of sustained delivery systems for topical drugs permitting less frequent dosing is of continuing interest for dermatological therapy. Areas covered: This potential of polymeric film-forming systems (FFS), created in situ on the skin, as sustained delivery platforms for topical drug delivery is reviewed. Key formulation parameters that determine delivery efficiency are considered focussing on those that permit a drug reservoir to be established in the upper layers of the skin and/or on the skin surface from which release can be sustained over a prolonged period. The advantageous and superior cosmetic attributes of FFS (compared to conventional semi-solid formulations) that offer significantly improved patient compliance are also addressed. Expert opinion: The promise of polymeric FFS as convenient and aesthetic platforms for sustained topical drug delivery is clear. Manipulation of the formulation allows the delivery profile to be customized and optimized to take advantage of both a rapid, initial input of drug into the skin (likely due to a transient period of supersaturation) and a slower, controlled release over an extended time from the residual film created thereafter.</p

Multi-mode photonic crystal fibers for VCSEL based data transmission

Quasi error-free 10 Gbit/s data transmission is demonstrated over a novel type of 50 micron core diameter photonic crystal fiber with as much as 100 m length. Combined with 850$ nm VCSEL sources, this fiber is an attractive alternative to graded-index multi-mode fibers for datacom applications. A comparison to numerical simulations suggests that the high bit-rate may be partly explained by inter-modal diffusion.Comment: Accepted for Optics Expres
