The âglass ceilingâ and empowerment of Qatari women for employment in Qatar.
Qatar is rapidly transforming from a traditional conservative and modest society to a more open, modern and technologically advanced society. Qatar has made significant strides over the recent years in increasing the participation of women in higher education and in the Qatari workforce (Scott-Jackson, 2015). Women comprise 24% of the Qatari population and 18% of the workforce (MDPS, 2015), however, they remain concentrated in entry-level administrative jobs (Al Ansari, 2012) and mostly in the public sector. Is this inequality of participation of women in higher levels of Qatari organizations, a Glass Ceiling phenomenon that has been noticed in other countries and global organizations? The answer from similar previous research is âYesâ and this dissertation is an endeavor to further build on these reasons and highlight how this problem has sprouted in Qatar. Using an employment effectiveness route, to make employees both men and women, express their views of their current work experiences and their likelihood to continue or leave employment and complete their career objectives in the current organization, this dissertation will help understand whether the Glass Ceiling has external reasons or is it self-inflicted. Self-infliction can be a reason from the lack of enthusiasm to progress into senior roles by women themselves due to the Islamic and patriarchal society values and the influence that this has had on women in Qatar and the entire middle east region in general (Ermis-Mert, A., 2018). The objective of this research is to find not only the reasons for the Glass Ceiling but also the solutions of how to use public policies and driving cultural changes to overcome this problem and to see Qatar fulfilling its vision 2030 in its entirety
MACHOs, White Dwarfs, and the Age of the Universe
(Abridged Abstract) A favored interpretation of recent microlensing
measurements towards the Large Magellanic Cloud implies that a large fraction
(i.e. 10--50%) of the mass of the galactic halo is composed of white dwarfs. We
compare model white dwarf luminosity functions to the data from the
observational surveys in order to determine a lower bound on the age of any
substantial white dwarf halo population (and hence possibly on the age of the
Universe). We compare various theoretical white dwarf luminosity functions, in
which we vary hese three parameters, with the abovementioned survey results.
From this comparison, we conclude that if white dwarfs do indeed constitute
more than 10% of the local halo mass density, then the Universe must be at
least 10 Gyr old for our most extreme allowed values of the parameters. When we
use cooling curves that account for chemical fractionation and more likely
values of the IMF and the bolometric correction, we find tighter limits: a
white dwarf MACHO fraction of 10% (30%) requires a minimum age of 14 Gyr (15.5
Gyr). Our analysis also indicates that the halo white dwarfs almost certainly
have helium-dominated atmospheres.Comment: Final version accepted for publication, straight TeX formate, 6 figs,

Improved Detection Rates for Close Binaries Via Astrometric Observations of Gravitational Microlensing Events
In addition to constructing a Galactic matter mass function free from the
bias induced by the hydrogen-burning limit, gravitational microlensing allows
one to construct a mass function which is less affected by the problem of
unresolved binaries (Gaudi & Gould). However, even with the method of
microlensing, the photometric detection of binaries is limited to binary
systems with relatively large separations of of their combined
Einstein ring radius, and thus the mass function is still not totally free from
the problem of unresolved binaries. In this paper, we show that by detecting
distortions of the astrometric ellipse of a microlensing event with high
precision instruments such as the {\it Space Interferometry Mission}, one can
detect close binaries at a much higher rate than by the photometric method. We
find that by astrometrically observing microlensing events, of
binaries with separations of can be detected with the detection
threshold of 3%. The proposed astrometric method is especially efficient at
detecting very close binaries. With a detection threshold of 3% and a rate of
10%, one can astrometrically detect binaries with separations down to .Comment: total 14 pages, including 5 Figures and no Table (For figure 1,

A New Channel for the Detection of Planetary Systems Through Microlensing: I. Isolated Events Due to Planet Lenses
We propose and evaluate the feasibility of a new strategy to search for
planets via microlensing. This new strategy is designed to detect planets in
"wide" orbits, i.e., with orbital separation, greater than .
Planets in wide orbits may provide the dominant channel for the microlensing
discovery of planets, particularly low-mass (e.g., Earth-mass) planets. This
paper concentrates on events in which a single planet serves as a lens, leading
to an isolated event of short duration. We point out that a distribution of
events due to lensing by stars with wide-orbit planets is necessarily
accompanied by a distribution of shorter- duration events. The fraction of
events in the latter distribution is proportional to the average value of
, where is the ratio between \pl and stellar masses. The position
of the peak or peaks also provides a measure of the mass ratios typical of
planetary systems. We study detection strategies that can optimize our ability
to discover isolated short-duration events due to lensing by planets, and find
that monitoring employing sensitive photometry is particularly useful. If
planetary systems similar to our own are common, even modest changes in
detection strategy should lead to the discovery of a few isolated events of
short duration every year. We therefore also address the issue of the
contamination due to stellar populations of any microlensing signal due to
low-mass MACHOs. We describe how, even for isolated events of short duration,
it will be possible to test the hypothesis that the lens was a planet instead
of a low-mass MACHO, if the central star of the planetary system contributes a
measurable fraction of the baseline flux.Comment: 37 pages, 6 figure. To be published in the Astrophysical Journal.

Second Backbend in the Mass A ~ 180 Region
Within the framework of selfconsistent cranked Hartree-Fock- Bogoliubov
theory(one-dimensional) we predict second backbend in the yrast line of Os-182
at , which is even sharper than the first one observed
experimentally at .
Around such a high spin the structure becomes multi-quasiparticle type, but
the main source of this strong discontinuity is a sudden large alignment of
i_13/2 proton orbitals along the rotation axis followed soon by the alignment
of j_15/2 neutron orbitals. This leads to drastic structural changes at such
high spins. When experimentally confirmed, this will be observed for the first
time in this mass region, and will be at the highest spin so far.Comment: 13 pages, 4 ps figure
Are logics enough? Framing as an alternative tool for understanding institutional meaning making
Understanding institutions requires attending both to their social fact qualities and to the bidirectional nature of institutional processes as they influence and are influenced by actors. We advocate for frames and framing as tools to elucidate meaning making activities, and to explain whether and how meanings subsequently spread, scale up, and perhaps become widely institutionalized. Frames as cognitive structures provide resources for actors and shape what they see as possible, while framing as an interaction process is a source of agency that is imbedded in the everyday activities of individuals, groups, and organizations. In making the case for the framing approach, we consider how the extensive use of the logics approach in organization theory research has created confusion about what logics are and how they accommodate both structure and agency. We conclude with a discussion of the phenomenological and ontological potential of frames and framing
