Globalisation and health security: a case study of distant individual risk perceptions of the 2014 Ebola outbreak
The wider awareness and recognition of human security threats has developed over the last several decades. Spurred on by globalization, greater human mobility, global media, economic interconnectedness and technological advancements, the securitization of non-military security threats have deepened and widened security discourses. The percieved risk posed by truly global threats have resulted in new international regimes and cooperation, national governments have reevaluated their national security strategies, and grassroots movements have revealed and mobileized individuals around the world to action. Global health security threats, and in particular, pandemic diseases, are one just one of many threats currently facing the global community that has the potential to envoke fear and feelings of insecurity and panic, particularly when securitized through twenty four hour news networks and social media. The purpose of this study is to explore the securitization process of a health security threat, the 2014 Ebola outbreak, and risk perceptions of individuals living in a global city geographically distant from the outbreak. This study reports the findings from interviews with eleven individuals based in the United Arab Emirates to explore their individual risk perceptions of the outbreak of the Ebola virus, and to understand how information about the outbreak was obtained, processed and consequently construed by these individuals. The findings suggested that with the increasing securitization of diseases, individual risk perceptions of the 2014 Ebola outbreak were a reflection of a variety of discourses concerning the security issue at the national and global levels. Therefore, in light of the increasing emergence and re-emergence of pandemic diseases and transborder global threats, it is important to consider individual perceptions of the threats and the influence of government, media (traditional and social media), and individual experiences in a global and interconnected world
Tourism development in Kuwait: examining the political-economic challenges in a unique rentier economy
This article explores the challenges Kuwait faces to develop tourism due to the particularly unique political-economic system of popular rentierism. Kuwait’s tourism industry is relatively underdeveloped in comparison to other Gulf Cooperation Council countries and has not received much attention by tourists, policy-makers, and scholars. This study provides both a macro-level analysis of the political economic obstacles to tourism development in Kuwait and the more micro-level challenges that have resulted, particularly in relation to proposed mega-development projects. While insights from this study are useful for understanding the role of tourism in the rentier economies, this study also further theorises tourism within the field of international relations and political economy and shows how tourism development is of particular importance for public diplomacy in the current global arena
Evolution of twin-beam in active optical media
We study the evolution of twin-beam propagating inside active media that may
be used to establish a continuous variable entangled channel between two
distant users. In particular, we analyze how entanglement is degraded during
propagation, and determine a threshold value for the interaction time, above
which the state become separable, and thus useless for entanglement based
manipulations. We explicitly calculate the fidelity for coherent state
teleportation and show that it is larger than one half for the whole range of
parameters preserving entanglemenent.Comment: several misprints correcte
Superspace formulation of general massive gauge theories and geometric interpretation of mass-dependent BRST symmetries
A superspace formulation is proposed for the osp(1,2)-covariant Lagrangian
quantization of general massive gauge theories. The superalgebra os0(1,2) is
considered as subalgebra of sl(1,2); the latter may be considered as the
algebra of generators of the conformal group in a superspace with two
anticommuting coordinates. The mass-dependent (anti)BRST symmetries of proper
solutions of the quantum master equations in the osp(1,2)-covariant formalism
are realized in that superspace as invariance under translations combined with
mass-dependent special conformal transformations. The Sp(2) symmetry - in
particular the ghost number conservation - and the "new ghost number"
conservation are realized as invariance under symplectic rotations and
dilatations, respectively. The transformations of the gauge fields - and of the
full set of necessarily required (anti)ghost and auxiliary fields - under the
superalgebra sl(1,2) are determined both for irreducible and first-stage
reducible theories with closed gauge algebra.Comment: 35 pages, AMSTEX, precision of reference
Fair trade learning: ethical standards for community-engaged international volunteer tourism
The purpose of this paper is to articulate a set of ethical standards for international volunteer tourism. The standards are focused on promoting fair trade learning principles in the management and operation of volunteer programmes. Because of the unique social mission, research, and evaluation capacities of higher education, we propose first applying these principles specifically to international volunteer programmes operating at the university-community nexus. These standards have emerged through a collaborative, in-person and online process during the last two years with input by numerous concerned global citizens, international education practitioners and researchers, nongovernmental organization representatives, and community members. The document shared below represents current ‘best practice’ for maximizing the benefits and minimizing the negative impacts of volunteer tourism programmes for both host communities and volunteers
The Counterpart Principle of Analogical Support by Structural Similarity
We propose and investigate an Analogy Principle in the context of Unary Inductive Logic based on a notion of support by structural similarity which is often employed to motivate scientific conjectures
Unsupervised classification and areal measurement of land and water coastal features on the Texas coast
Multispectral scanner (MSS) digital data from ERTS-1 was used to delineate coastal land, vegetative, and water features in two portions of the Texas Coastal Zone. Data (Scene ID's 1037-16244 and 1037-16251) acquired on August 29, 1972, were analyzed on NASA Johnson Space Center systems through the use of two clustering algorithms. Seventeen to 30 spectrally homogeneous classes were so defined. Many classes were identified as being pure features such as water masses, salt marsh, beaches, pine, hardwoods, and exposed soil or construction materials. Most classes were identified to be mixtures of the pure class types. Using an objective technique for measuring the percentage of wetland along salt marsh boundaries, an analysis was made of the accuracy of areal measurement of salt marshes. Accuracies ranged from 89 to 99 percent. Aircraft photography was used as the basis for determining the true areal size of salt marshes in the study sites
