aim: it seems that positive outcomes resulting from the autonomy in the job, is dependent on a number of factors. autonomy means the interdependence and freedom of staff in planning and organizing work and it has different levels. the aim of current research is to investigate the role of task reflection in relation of autonomy and skill utilization. method: the research sample consisted of 324 ...

In this letter, we investigate the circular differential deflection of a light beam refracted at the interface of an optically active medium. We show that the difference between the angles of deviation of the two circularly polarized components of the transmitted beam is enhanced manyfold near total internal reflection, which suggests a simple way of increasing the limit of detection of chiro-o...

IP prefixes undermine three goals of Internet routing: accurate reflection of network-layer reachability, secure routing messages, and effective traffic control. This paper presents Atomic IP (AIP), a simple change to Internet addressing (which in fact reverts to how addressing once worked), that allows Internet routing to achieve these goals.

Thirteen simple closed geodesics are found in the lemniscate. Among these are nine “mirrors”—geodesics of reflection symmetry—which generate the full octahedral group and determine a triangulation of the lemniscate as a disdyakis dodecahedron. New visualizations of the lemniscate are presented.

A simple and inexpensive technique for enhancing the visibility of corneal endothelial cells in specular reflection biomicroscopy involves the insertion of a circular polarizer in front of the patient's eye, intersecting both the incident and reflected light beams. This filter significantly reduces the glare from the epithelium and enables more comfortable and clearer viewing of the endothelial...

A simple, convenient and label-free fiber optic detection system based on the characteristic property, 'anomalous reflection (AR)' of gold was developed and preliminary experiments showed that the AR signals were sensitive enough to monitor protein-peptide interactions on solid surfaces.

Utilizing the underlying physics of evanescent-wave amplification by a negative-refractive-index slab, it is shown that evanescent waves with specific spatial frequencies can also be amplified without any reflection simply by two dielectric planar waveguides. The simple configuration allows one to take advantage of the high resolution limit of a high-refractive-index material without contact wi...

The article shows a simple way of calibrating the strength of the theory of positive induction, ID1. Crucially the proof exploits the equivalence of Σ 1 1 dependent choice and ω-model reflection for Π2 formulae over ACA0. Unbeknown to the authors, D. Probst had already determined the proof-theoretic strength of ID1 in [13].

We derive a simple formula for the action of a finite crystallographic Coxeter group on the cohomology of its associated complex toric variety, using the method of counting rational points over finite fields, and the Hodge structure of the cohomology. Various applications are given, including the determination of the graded multiplicity of the reflection representation.

In the present paper, we give a graph-theoretic description for representatives of all the congruence classes of presentations (or r.c.p. for brevity) for the imprimitive complex reflection groups G(m, 1, n) and G(m, m, n). We have three main results. The first main result is to establish a bijection between the set of all the congruence classes of presentations for the group G(m, 1, n) and the...
