The Lived Experiences of Mentoring Nurses in Malaysia
Background: Being a nursing mentor is not an entirely new concept in nursing. However, it is a new phenomenon in the nursing profession in Malaysia. The nursing administration and the senior nurses in Malaysia have claimed that they have started a mentorship program by having senior nurses shadow new graduate nurses for the past two to three years ago. With no study found in Malaysia investigating the lived experiences of mentors mentoring new registered nurses, it led the researcher to develop this research that explores the real life experiences of these senior Malaysian nurses who mentor neophyte nurses.Objectives: This research explores and describes the lived experiences of nurses mentoring neophyte or new registered nurses at one of the major hospital in the Malaysia Borneo and how such experiences influence their daily routine as a nurse and also as a mentor. The research will also attaches meaning to these experiences and identifies both positive and negative experiences as a mentor to neophyte.Methods: The experiences of nurses mentoring the neophyte in the clinical area were captured using a qualitative approach to research and further viewed through methods informed by phenomenology, which used interpretive and descriptive semi-structured interviews. Hermeneutic interpretive phenomenology was used in the focus to analyze interview transcript into textual expression of the mentors. Three main themes emerge from this study are being unprepared and challenged, perceptions of mentees, mentor hope and desire
Generalized Browder's theorem for tensor product and elementary operators
The transfer property for the generalized Browder's theorem both of the
tensor product and of the left-right multiplication operator will be
characterized in terms of the -Weyl spectrum inclusion. In addition, the
isolated points of these two classes of operators will be fully characterized.Comment: 11 pages; original research articl
The Complex Way to Laser Diode Spectra: Example of an External Cavity Laser With Strong Optical Feedback
An external cavity laser with strong grating-filtered feedback to an antireflection-coated facet is studied with a time-domain integral equation for the electric field, which reproduces the modes of the oscillation condition as steady-state solutions. For each mode, the stability and spectral behavior is determined by analysis of the location of side modes in the complex frequency plane. The complex frequency diagrams are shown to be a useful tool to determine the self-stabilization effect of mode coupling and its dependence on laser parameters and external cavity design. The model is used to simulate the large signal time evolution after start from unstable mode
New insights from inside-out Doppler tomography
We present preliminary results from our investigation into using an
'inside-out' velocity space for creating a Doppler tomogram. The aim is to
transpose the inverted appearance of the Cartesian velocity space used in
normal Doppler tomography. In a comparison between normal and inside-out
Doppler tomograms of cataclysmic variables, we show that the inside-out
velocity space has the potential to produce new insights into the accretion
dynamics in these systems.Comment: 4 pages, 4 figures, conference: The Golden Age of Cataclysmic

The Demand for Sons: Evidence from Divorce, Fertility, and Shotgun Marriage
This paper shows how parental preferences for sons versus daughters affect divorce, child custody, marriage, shotgun marriage when the sex of the child is known before birth, and fertility stopping rules. We document that parents with girls are significantly more likely to be divorced, that divorced fathers are more likely to have custody of their sons, and that women with only girls are substantially more likely to have never been married. Perhaps the most striking evidence comes from the analysis of shotgun marriages. Among those who have an ultrasound test during their pregnancy, mothers carrying a boy are more likely to be married at delivery. When we turn to fertility, we find that in families with at least two children, the probability of having another child is higher for all-girl families than all-boy families. This preference for sons seems to be largely driven by fathers, with men reporting they would rather have a boy by more than a two to one margin. In the final part of the paper, we compare the effects for the U.S. to five developing countries.
D-touch: A Consumer-Grade Tangible Interface Module and Musical Applications
We define a class of tangible media applications that can be implemented on consumer-grade personal computers. These applications interpret user manipulation of physical objects in a restricted space and produce unlocalized outputs. We propose a generic approach to the implementation of such interfaces using flexible fiducial markers, which identify objects to a robust and fast video-processing algorithm, so they can be recognized and tracked in real time. We describe an implementation of the technology, then report two new, flexible music performance applications that demonstrate and validate it
Minimal Asymmetric Dark Matter
In the early Universe, any particle carrying a conserved quantum number and
in chemical equilibrium with the thermal bath will unavoidably inherit a
particle-antiparticle asymmetry. A new particle of this type, if stable, would
represent a candidate for asymmetric dark matter (DM) with an asymmetry
directly related to the baryon asymmetry. We study this possibility for a
minimal DM sector constituted by just one (generic) multiplet
carrying hypercharge, assuming that at temperatures above the electroweak phase
transition an effective operator enforces chemical equilibrium between
and the Higgs boson. We argue that limits from DM direct detection searches
severely constrain this scenario, leaving as the only possibilities scalar or
fermion multiplets with hypercharge , preferentially quintuplets or
larger representations, and with a mass in the few TeV range.Comment: 9 pages, 2 figures, included t-channel scattering, added details on
