The Endurance of Arab Authoritarian Regimes: A Study of Jordan and Algeria
The endurance of Arab authoritarian regimes has been quite daunting, especially with the rise of the Arab Spring. Some Arab regimes have ruled with domination and repression since the nineteenth century. These regimes stand out globally with respect to the number of democratic countries. Even with the recent rebellions, the rise of the Arab Spring, starting in 2011, a number of Arab regimes still continue to thrive and remain intact under authoritarian rule. This includes quite a number of Arab states that have faced uprisings during the Arab Spring, but have not implemented a new democratic system or elected a new leader, such as Syria. With this fascinating reality of Arab authoritarian regimes, I set out to find the reason for the endurance of Arab authoritarian regimes, noting that this was not a simple coincidence. My goal was to find out what exactly allowed Arab authoritarian regimes to remain stable, whether it was political strategies or economic resources, even in the face of the Arab Spring. Overall, I was determined to obtain a grip on one solid and plausible reason as to why Arab authoritarian leaders have endured for so long, or at least a brief number of reasons. Arab authoritarianism has allowed the regimes to endure since the nineteenth century and continue to do so with protests and grievances amongst citizens. I decided to choose the topic of Arab authoritarian endurance because I understood the importance in exposing the backbone of the regimes. I truly believe that learning about the reasons for Arab authoritarian endurance empowers people of all backgrounds with the knowledge of strategies that dictates the lives of people in Arab states. Not only does this topic allow people to understand the power of Arab regimes in being able to rule with a strong fist, but also enables people to comprehend how most Arab authoritarian regimes are able to continue to real with a stable regime even with the recent Arab uprisings. The endurance of Arab authoritarianism is most important in being able to analyze and compare Arab regimes that have fallen to the Arab Spring and the ones that continue to maintain durability. In order to complete this research task, I embarked on extensive research and used various methodologies. My thesis is split into four sections, with two main chapters. My first section is the literature review. I completed this portion by researching a broad range of arguments by a number of different scholars, such as the politicized education system, the condition of the coercive forces, hydrocarbon exports, and so on for the endurance of Arab authoritarian regimes. These arguments included reasons prior to the Arab Spring. The arguments used in my literature review all fall under political, economic, cultural, security, or educational reasons. My two main chapters consist of Jordan and Algeria. I chose these two regimes as my core chapters to create a balanced argument, as Jordan is a constitutional monarchy and Algeria is a semi-presidential republic. My methodologies for these chapters included conducting extensive research on each country with concern to the recent protests, government responses, and theories amongst scholars as to why these regimes continue to endure even after the Arab Spring. I also learned about the structure of each regime, such as its components, government supporters, government opponents, and security forces. I provided the structure of each regime in the beginning of each core chapter. Each of these countries have unique factors specific to their endurance, which helped me produce a compelling thesis
Risky choice in younger versus older adults: Affective context matters
Earlier frameworks have indicated that older adults tend to experience decline in their deliberative decisional capacity, while their affective abilities tend to remain intact (Peters, Hess, VĂ€stfjĂ€ll, & Auman, 2007). The present study applied this framework to the study of risky decision-making across the lifespan. Two versions of the Columbia Card Task (CCT) were used to trigger either affective decision-making (i.e., the âwarmâ CCT) or deliberative decision-making (i.e., the âcoldâ CCT) in a sample of 158 individuals across the lifespan. Overall there were no age differences in risk seeking. However, there was a significant interaction between age and condition, such that older adults were relatively more risk seeking in the cold condition only. In terms of everyday decision-making, context matters and risk propensity may shift within older adults depending upon the context
Matter Effects in Atmospheric Neutrino Oscillations
The Kamiokande II and IMB data on contained events induced by atmospheric
neutrinos exhibit too low a ratio of muons to electrons, which has been
interpreted as a possible indication of neutrino oscillations. At the same
time, the recent data on upward--going muons in underground detectors have
shown no evidence for neutrino oscillations, strongly limiting the allowed
region of oscillation parameter space. In this paper we confront different
types of neutrino oscillation hypotheses with the experimental results. The
matter effects in and in oscillations are discussed and shown to affect
significantly the upward--going muons.Comment: LaTeX, 13 pages, 4 figures (appended as postscript file in the end of

Theorising the value of collage in exploring educational leadership
This article contributes to theorising the value of collage as a methodological approach. It begins with a discussion of the methodological difficulties of exploring hidden meanings and individual experience through the research process. The illuminative potential of arts-based methodologies in qualitative research is then investigated. The article makes the case for the specific advantages of using collage to explore the experience of leadership, through a discussion of two collage-based studies. It proposes a variant of the âthink aloudâ process, used in conjunction with collage, as a route to producing deep understandings of the multiple ways in which leadership is experienced and understood as a social process. The argument is made that collage enables the accessing and sharing of profound levels of experience not accessible through words alone, and considers the impact of the physicality of collage on its potential to release these profound insights. A five-stage process for the analysis of collage is then set out. The article concludes by offering a theory of the value of collage as a methodological approach to exploring experiences of leadership, through use of the concepts of physicality, wholeness and participant agency.Peer reviewe
Free and smooth boundaries in 2-D finite-difference schemes for transient elastic waves
A method is proposed for accurately describing arbitrary-shaped free
boundaries in single-grid finite-difference schemes for elastodynamics, in a
time-domain velocity-stress framework. The basic idea is as follows: fictitious
values of the solution are built in vacuum, and injected into the numerical
integration scheme near boundaries. The most original feature of this method is
the way in which these fictitious values are calculated. They are based on
boundary conditions and compatibility conditions satisfied by the successive
spatial derivatives of the solution, up to a given order that depends on the
spatial accuracy of the integration scheme adopted. Since the work is mostly
done during the preprocessing step, the extra computational cost is negligible.
Stress-free conditions can be designed at any arbitrary order without any
numerical instability, as numerically checked. Using 10 grid nodes per minimal
S-wavelength with a propagation distance of 50 wavelengths yields highly
accurate results. With 5 grid nodes per minimal S-wavelength, the solution is
less accurate but still acceptable. A subcell resolution of the boundary inside
the Cartesian meshing is obtained, and the spurious diffractions induced by
staircase descriptions of boundaries are avoided. Contrary to what occurs with
the vacuum method, the quality of the numerical solution obtained with this
method is almost independent of the angle between the free boundary and the
Cartesian meshing.Comment: accepted and to be published in Geophys. J. In
Evidence for Low Extinction in Actively Star Forming Galaxies at z6.5
We present a search for the [CII] 158micron fine structure line (a main
cooling line of the interstellar medium) and the underlying far-infrared (FIR)
continuum in three high-redshift (6.6<z<8.2) star-forming galaxies using the
IRAM Plateau de Bure interferometer. We targeted two Lyman-Alpha-selected
galaxies (Lyman-Alpha-Emitters, LAEs) with moderate UV-based star formation
rates (SFR~20 M_sun/yr; Himiko at z=6.6 and IOK-1 at z=7.0) and a Gamma Ray
Burst (GRB) host galaxy (GRB 090423 at z~8.2). Based on our 3 sigma rest-frame
FIR continuum limits, previous (rest-frame) UV continuum measurements and
spectral energy distribution (SED) fitting, we rule out SED shapes similar to
highly obscured galaxies (e.g. Arp220, M82) and less extreme dust-rich nearby
spiral galaxies (e.g. M51) for the LAEs. Conservatively assuming a SED shape
typical of local spiral galaxies we derive upper limits for the FIR-based star
formation rates (SFRs) of ~70 M_sun/yr, ~50 M_sun/yr and ~40 M_sun/yr for
Himiko, IOK-1 and GRB 090423, respectively. For the LAEs these limits are only
a factor ~3 higher than the published UV-based SFRs (uncorrected for
extinction). This indicates that the dust obscuration in the z>6 LAEs studied
here is lower by a factor of a few than what has recently been found in some
LAEs at lower redshift (2<z<3.5) with similar UV-based SFRs. A low obscuration
in our z>6 LAE sample is consistent with recent rest-frame UV studies of z~7
Lyman-Break-Galaxies (LBGs).Comment: Accepted for publication in the Astrophysical Journa
Flagships and tumbleweed: A history of the politics of gender justice work in Oxfam GB 1986â2015
This article contributes to scholarship on the political nature of feministsâ work in international development NGOs. The case study of Oxfam GB (OGB) is contemporary history, based on compiling a brief history of gender justice work between 1986 and 2014 and 18 months of part-time participant-observation fieldwork during 2014â15. I describe funding pressures and imperatives, contestations of meaning and power struggles within OGB and argue that gender justice becomes entangled in both internal and the external politics of international development. This is part of a wider research programme about how ideas on gender equality norms travel between and around development organizations, so I finally draw conclusions about how norms are contested and embodied. The shapeshifting political nature of feminist work challenges prevailing theories about how norms and ideas travel and take hold within organizations
Evangelical Christianity and Womenâs Changing Lives
Women have outnumbered men as followers of Christianity at least since the transition to industrial capitalist modernity in the West. Yet developments in women's lives in relation to employment, family and feminist values are challenging their Christian religiosity. Building on a new strand of gender analysis in the sociology of religion, this article argues that gender is central to patterns of religiosity and secularization in the West. It then offers a case study of evangelical Christianity in England to illustrate how changes in women's lives are affecting their religiosity. Specifically, it argues that evangelical Christianity continues to be important among women occupying more traditional social positions (as wives and mothers), but adherence is declining among the growing number whose lives do not fit this older model
Comparing and contrasting the and solutions to the atmospheric neutrino problem with SuperKamiokande data
The and solutions to the
atmospheric neutrino problem are compared with SuperKamiokande data. The
differences between these solutions due to matter effects in the Earth are
calculated for the ratio of -like to -like events and for up-down flux
asymmetries. These quantities are chosen because they are relatively
insensitive to theoretical uncertainties in the overall neutrino flux
normalisation and detection cross-sections and efficiencies. A
analysis using these quantities is performed yielding ranges which
are approximately given by and for
for the and solutions, respectively. Values of smaller than about
eV are disfavoured for the
solution, suggesting that future long baseline experiments should see a
positive signal if this scenario is the correct one.Comment: revtex, 22 pages, 12 figure
