The immigration issue in the European electoral campaign in the UK : text-mining public debate from newspapers and social media
No full textIn recent years, the issue of immigration has become increasingly salient in the UK political
and media debate. Moreover, with the development and persistence of the economic and
financial crisis within the EU, immigration has been linked to growing opposition and criticism
towards the European Union. In a country in which Euroscepticism has historically
been high compared to countries in continental Europe, EU immigration-related statements
connected to EU free-border agreements became more widespread. For this reason, we expect
immigration to be a prominent issue in the electoral campaign of the upcoming 2014
European Parliament elections in the media. By covering (potential) EU immigrants and
EU immigration issues in a certain way, media tend to promote or restrain certain ideas of
immigration, that might eventually affect public’s views. In fact, we know from previous
studies that immigration, particularly in times of economic crisis, is a challenge for society
that can be framed not only in positive or negative terms, but also in economic or cultural
terms.
By looking at the news coverage of several newspapers, selected according to their political
orientations and including both broadsheets and tabloids, this study first considers
the salience of coverage of EU immigrants and EU immigration issues in UK newspapers
in the three months preceding the EU elections of May 2014. It further explores whether
news coverage of different newspapers is framed in terms of economic (e.g. jobs) or cultural
(e.g. identity) terms. In addition, we mine information from social media to discover
how the immigration debate is framed by politically engaged members of the public on
these platforms. Although inferring public opinion from social media can be problematic,
it is a rewarding approach given the volume of public text available, and the ability to
identify political affiliations through network connections. Understanding representation
of immigration and its connections with public opinion is crucial not only in order to contribute
to the scholarly debate on anti-immigration and Euroscepticism attitudes, but also
to better inform public policy decisions

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

Simulation of thermal plant optimization and hydraulic aspects of thermal distribution loops for large campuses
No full textFollowing an introduction, the author describes Texas A&M University and its utilities system. After that, the author presents how to construct simulation models for chilled water and heating hot water distribution systems. The simulation model was used in a $2.3 million Ross Street chilled water pipe replacement project at Texas A&M University. A second project conducted at the University of Texas at San Antonio was used as an example to demonstrate how to identify and design an optimal distribution system by using a simulation model. The author found that the minor losses of these closed loop thermal distribution systems are significantly higher than potable water distribution systems. In the second part of the report, the author presents the latest development of software called the Plant Optimization Program, which can simulate cogeneration plant operation, estimate its operation cost and provide optimized operation suggestions. The author also developed detailed simulation models for a gas turbine and heat recovery steam generator and identified significant potential savings. Finally, the author also used a steam turbine as an example to present a multi-regression method on constructing simulation models by using basic statistics and optimization algorithms. This report presents a survey of the author??s working experience at the Energy Systems Laboratory (ESL) at Texas A&M University during the period of January 2002 through March 2004. The purpose of the above work was to allow the author to become familiar with the practice of engineering. The result is that the author knows how to complete a project from start to finish and understands how both technical and nontechnical aspects of a project need to be considered in order to ensure a quality deliverable and bring a project to successful completion. This report concludes that the objectives of the internship were successfully accomplished and that the requirements for the degree of Degree of Engineering have been satisfied
Small sets of complementary observables
No full textTwo observables are called complementary if preparing a physical object in an eigenstate of one of them yields a completely random result in a measurement of the other. We investigate small sets of complementary observables that cannot be extended by yet another complementary observable. We construct explicit examples of unextendible sets up to dimension 16 and conjecture certain small sets to be unextendible in higher dimensions. Our constructions provide three complementary measurements, only one observable away from the ultimate minimum of two. Almost all our examples in finite dimensions are useful for discriminating pure states from some mixed states, and they help to shed light on the complex topology of the Bloch space of higher-dimensional quantum systems.MOE (Min. of Education, S’pore)Published versio
Toxic equivalency factors (TEFs) after acute oral exposure of azaspiracid 1, 122 and 123 in mice
No full textAzaspiracids (AZAs) are marine algal toxins that can be accumulated by edible shellfish to cause a foodborne gastrointestinal poisoning in humans. In the European Union, only AZA1, 122 and 123 are currently regulated and their concentration in shellfish is determined through their toxic equivalency factors (TEFs) derived from the intraperitoneal lethal potency in mice. Nevertheless, considering the potential human exposure by oral route, AZAs TEFs should be calculated by comparative oral toxicity data. Thus, the acute oral toxicity of AZA1, 122 and 123 was investigated in female CD-1 mice treated with different doses (AZA1: 135\u20131100 \u3bcg/kg; AZA2 and AZA3: 300\u20131100 \u3bcg/kg) and sacrificed after 24 h or 14 days. TEFs derived from the median lethal doses (LD50) were 1.0, 0.7 and 0.5, respectively for AZA1, 122 and 123. In fact, after 24 h from gavage administration, LD50s were 443 \u3bcg/kg (AZA1; 95% CL: 350 12561 \u3bcg/kg), 626 \u3bcg/kg (AZA2; 95% CL: 430 12911 \u3bcg/kg) and 875 \u3bcg/kg (AZA3; 95% CL: 757 121010 \u3bcg/kg). Mice dead more than 5 h after the treatment or those sacrificed after 24 h (doses: 65175 \u3bcg AZA1/kg, 65500 \u3bcg AZA2/kg and 65600 \u3bcg AZA3/kg) showed enlarged pale liver, while increased serum markers of liver alteration were recorded even at the lowest doses. Blood chemistry revealed significantly increased serum levels of K+ ions ( 65500 mg/kg), whereas light microscopy showed tissue changes in the gastrointestinal tract, liver and spleen. No lethality, macroscopic, tissue or haematological changes were recorded two weeks post exposure, indicating reversible toxic effects. LC\u2013MS/MS analysis of the main organs showed a dose-dependency in gastrointestinal absorption of these toxins: at 24 h, the highest levels were detected in the stomach and, in descending order, in the intestinal content, liver, small intestine, kidneys, lungs, large intestine, heart as well as detectable traces in the brain. After 14 days, AZA1 and AZA2 were still detectable in almost all the organs and intestinal content.Peer reviewed: YesNRC publication: Ye
Intern experience at CH���M Hill, Inc.: an internship report
No full textIncludes author's vita"Submitted to the College of Engineering of Texas A&M University in partial
fulfillment of the requirement for the degree of Doctor of Engineering."Includes bibliographical referencesA review of the author's internship experience with CH���M HILL, Inc.
during the period September 1975 through May 1976 is presented. During this nine month
internship the author worked as an Engineer II in the Industrial Processes discipline of this
large consulting engineering firm... The author's prime responsibility was as one of three
lead design engineers on the design of a large wastewater treatment facility for a pulp mill
in Hoquiam, Washington owned by ITT Rayonier Inc. The work generally consisted of the design
of individual treatment units and associated piping and pumping. The purpose of the project
was to provide wastewater treatment capabilities that would satisfy the effluent limitations
(standards) imposed upon the mill by the State of Washington Department of Ecology and the
U.S. Environmental Protection Agency. The author's assignment also entailed necessary
interaction with the project manager and other CH���M HILL design engineers and support staff
members, the client's representatives, and representatives of two other consulting engineering
firms working on the project. Thus, the internship position at CH���M HILL provided considerable
experience coordinating the author's work with the work of other engineers, guiding the design
and administrative efforts of a support staff, and interacting regularly with the client and
other consulting firms. This broad exposure to a variety of engineering and organizational
problems provided a valuable educational experience
Transition to turbulence in a qblique shock-wave/boundary-layer interaction at M=15
No full textDirect numerical simulations are carried out for different forcing techniques to trigger transition during the interaction between an oblique shock-wave and a laminar boundary-layer at M = 1.5. Three forcing methods are used: a) forcing of oblique unstable modes, whose shape and behaviour are determined by the local linear stability theory, b) broadband free-stream acoustic disturbances, and c) a cold plasma flow control device. While the oblique-mode breakdown is dominant for low-amplitude forcing, long streaky structures drive the transition process in a high-amplitude disturbance environment. LES are also performed on the experimental setup by the Institute of Theoretical and Applied Mechanics (ITAM) from Novosibirsk State University with cold plasma actuation. As well as the disturbance type, the effect of Reynolds number and forcing amplitude will be investigated
