description: Magnetic flux trapped on the surface of superconducting rotors of the Gravity Probe B (GP-B) experiment produces some signal in the SQUID readout. For the needs of GP-B error analysis and simulation of data reduction, this signal is calculated and analyzed in the paper. We first solve a magnetostatic problem for a point source (fluxon) on the surface of a sphere, finding the closed form elementary expression for the corresponding Green's function. Second, we calculate the flux through the pick-up loop as a function of the fluxon position. Next, the time dependence of a fluxon position, caused by rotor motion according to a symmetric top model, and thus the time signature of the flux are determined, and the spectrum of the trapped flux signal is analyzed. Finally, a multi-purpose program of trapped flux signal generation based on the above results is described, various examples of the signal obtained by means of this program are given, and their features are discussed.

description: Rhacophoridae   Remarks. – Delorme et al. (2005), Frost et al. (2006), and Wilkinson et al. (2002) convincingly demonstrated that Chirixalus Boulenger, 1893, is paraphyletic with respect to other rhacophorid genera. To avoid this paraphyly, Frost et al. (2006) placed C. palpebralis into their newly formed genus Feihyla, and Delorme et al. (2005) placed C. gracilipes into their new genus Aquixalus. Chirixalus romeri, C. ocellatus, and C. vittatus were left incerta sedis by Frost et al. (2006) although Wilkinson et al. (2002) indicates that C. vittatus may be most closely related to Polypedates Tschudi, 1838, and Frost et al. (2006) suspect that C. romeri and C. ocellatus may eventually be transferred into Feihyla. Frost et al. (2006) placed the remainder of Chirixalus in the synonymy of Chiromantis Peters 1854. However, it should be cautioned that this latter arrangement is based only on the phylogenetic placement of C. doriae (see Wilkinson et al., 2002) and should be regarded as tentative. Nonetheless, we believe that the classification of Frost et al. (2006: Appendix 7) provides a taxonomy, which, at this point, is most consistent with what is currently believed to be the best estimate of this groups evolutionary relationships.

description: Die Luftfeuchtigkeit wurde am Observatorium Hohenpeißenberg seit 1781 gemessen. Zuerst wurde ein Federkielhygrometer verwendet. Um die Qualität dieser Daten einschätzen zu können, wurde ein solches Instrument nachgebaut und damit Experimente und Vergleichsmessungen vorgenommen. Die Empfindlichkeit des Federkielhygrometers erwies sich als relativ hoch, doch nimmt die Einstellgeschwindigkeit mit abnehmender Temperatur beträchtlich zu. Dadurch entsteht eine große Streuung der Messwerte bei vorgegebener relativer Feuchte und die Ergebnissen sind nur auf etwa 10% genau. 1841 wurde ein unventiliertes Psychrometer in der von Lamont eingeführten Bauart eingesetzt. Die Datenqualität wurde untersucht und wurde für den Zeitraum 1842 bis 1867 mit einer Genauigkeit von ca. 1 hPa als ausreichend gut befunden, so dass die Messwerte als brauchbar eingestuft werden können. Unterhalb von 0°C treten häufig Überschreitungen des Sättigungsdampfdrucks auf. Nach einem Geräteausfall im Herbst 1867 trat ein bleibender Messfehler auf, weshalb die Daten von 1868 bis 1878 verworfen wurden. Untersuchungen zur Häufigkeitsverteilung der Temperatur und des Dampfdrucks ergaben, dass beide Parameter keiner Gauß-Verteilung unterliegen. Beim Wasserdampf deutet sich die Überlagerung zweier getrennter Moden an, die möglicherweise polaren und tropischen Luftmassen zuzuordnen sind. Moderne Daten ergeben eine gute Korrelation von Temperatur und Dampfdruck zur Temperatur des Ostatlantiks, eine Hohe Ozeantemperatur geht mit hoher Temperatur und hohem Dampfdruck am Hohen Peißenberg einher und umgekehrt. Da der Ozean eine Hauptquelle des Wasserdampfes ist, wirkt dessen gegenüber dem Kontinent phasenverschobener Jahresgang der Temperatur vor allem im Herbst und Winter temperaturerhöhend, da Wasserdampf die langwellige Abstrahlung von Wärmeenergie hemmt. Unterteilt man die historische Messperiode 1842 – 1867 in ein kühles und ein warmes Kollektiv, so zeigt die Häufigkeitsverteilung des Dampfdrucks für das warme Kollektiv eine Verschiebung zu höheren Dampfdrucken gegenüber dem kühlen Kollektiv. Eine vergleichbare Verschiebung lässt sich für moderne Dampfdruckmessungen erkennen, wenn hier gleichfalls der Untersuchungszeitraum 1980 – 2009 in ein warmes und ein kühles Kollektiv unterteilt wird. Dagegen lässt sich durch Mittelwerte dieser Sachverhalt weniger gut nachweisen.

description: The scaling limit $A_{\hbar,η}(\hat{sl_2})$ of the elliptic algebra $A_{q,p}(\hat{sl_2})$ is investigated. The limiting algebra is defined in terms of a continuous family of generators being Fourier harmonics of Gauss coordinates of the $L$-operator. Ding-Frenkel isomorphism between $L$-operator's and current descriptions of the algebra $A_{\hbar,η}(\hat{sl_2})$ is established and is identified with the Riemann problem on a strip. The representations, coalgebraic structure and intertwining operators of the algebra are studied.

description: The present study was conducted to extend what is known about the writing skills of low achieving postsecondary students. Using an archival data set, a sample of argumentative essays written by community college developmental (remedial) education students was analyzed. Scoring procedures for argumentation development were implemented based on a framework developed by Ferretti, Lewis, and Andrews-Weckerly (2009) and adapted by the current author to accommodate the tasks of the writing prompt. The goals of the study were: (1) to determine to what extent the argumentative essays written by community college remedial students are inclusive of functional argumentative elements, coherent, cohesive, and of high quality; and (2) to determine to what extent the written components (i.e., coherence, cohesion, inclusion of functional elements, length) and demographic characteristics of the writer (i.e., reading ability, science interest, science knowledge, gender, native language) contribute to the overall quality of argumentative essays. Descriptive statistics and ordinal logistic regression were used to analyze a total of 112 writing samples. It was found that on average, the argumentation in the essays was only partially developed and coherent; the essays contained a relatively moderate amount of functional elements and included a minimal amount of cohesive ties. The results also indicated that the written components of the argumentative essays and the demographic characteristics of the writer, when combined, significantly contribute to the overall quality of the argumentative essays. The coherence of the essays was found to have the highest odds ratio to essay quality in comparison to any other variable analyzed. These findings suggest the need for instruction focusing largely on essay coherence, as well as argumentation development, in order to improve argumentative writing quality.

 Remarks. – Nine specimens agree with Cochran’s (1927) description of the type series from Nong Khor in southeastern Thailand and Stuart & Emmett’s (2006) description of specimens from the central Cardamoms, and two specimens collected from the northeastern Cardamoms (Grismer et al., 2007a) in having the two outer fingers (digits III and IV) nearly opposable to the inner two (digits I and II); interorbital distance much greater than the width of the upper eyelid; SVL greater than 20 mm (SVL 26–35 mm in our sample); dorsum reddish-brown with dark, transverse blotches and barred limbs; head slightly wider than body; tibiotarsal articulation reaching the eye or slightly beyond it; toes nearly completely webbed; canthus angular; tympanum distinct. Taylor (1962) stated that the outer fingers are 2/3 webbed but in our specimens, webbing is restricted to the base with the fingers being 1/4–1/2 webbed at most.
 All specimens were calling while seated on small leaves of low bushes adjacent to temporary rain pools along the edge of the main trail. Stuart & Emmet (2006) report Chiromantis nongkhorensis from the central and southeastern Cardamoms and Grismer et al. (2007a) report it from the northeastern Cardamoms.

description: This thesis studies the power relations among the government, the village collective economic organization (VCEO), and the villagers in the redevelopment of urban villages in China by analyzing three cases - Liede Village, Yangji Village, and Wenchong Village in Guangzhou municipality. The case studies show that government involvement is the major force that drives the redevelopment and the degree of government involvement is based on the government's agenda rather than the needs of villages. Although the urban village only has limited negotiation power, villagers' active participation and continuous engagement can assist the redevelopment of urban villages and help to achieve a desirable redevelopment plan and compensation scheme. It also indicates that strong support from government and a collaborative partnership among the local government, the village collective economic organization (VCEO), and urban villagers are the keys to successful urban village redevelopments.

description: The idea of a natural duty of justice expresses our cosmopolitan duty to ensure that everyone’s human rights are institutionally protected and promoted. The state system is one way to specify this duty: Within a moral division of labor, states have an obligation to protect their citizens’ human rights, and the community of states as a whole has subsidiary obligations if states fail to do so. In areas of limited statehood, however, both the remains of the state and the international community often do not fulfill their obligations. Without relieving them of their obligations, this raises the question as to whether it is possible to assign human rights obligations to non-state actors operating in areas of limited statehood, such as TNCs or NGOs. Our core argument is that these non-state actors do indeed have specific human rights obligations, which can be specified by examining their special relations to their social environment. Making use of criteria prominent in the global justice debate, we propose to distinguish four types of special relations: membership, cooperation, negative impact, and power. The relation between a non-state actor and society, then, determines the social scope of its human rights obligations.
description: Die Idee einer natürlichen Gerechtigkeitspflicht erfasst unsere kosmopolitische Verant-wortung, allen Menschen Zugang zu Institutionen zu sichern, die ihre grundlegenden Menschenrechte schützen. Das Staatensystem spezifiziert diese Verantwortung: Im Rahmen einer globalen moralischen Arbeitsteilung haben Staaten die Verpflichtung, den Schutz der Menschenrechte ihrer Bürger zu gewährleisten. Die internationale Gemeinschaft hat die subsidiäre Verpflichtung zum Menschenrechtsschutz, falls einzelne Staaten ihren Verpflichtungen nicht gerecht werden. In Räumen begrenzter Staatlichkeit funktioniert diese Arbeitsteilung jedoch nicht. Ohne die Staaten oder die internationale Gemeinschaft aus ihrer Verantwortung zu entlassen, stellt sich die Frage, ob unter diesen Bedingungen nicht-staatlichen Akteuren spezifische Menschenrechtsverpflichtungen zukommen. Wir vertreten die These, dass nicht- staatliche Akteure tatsächlich solche Verpflichtungen haben. Diese ergeben sich aus dem Verhältnis zu ihrem sozialen Umfeld. Dabei bedienen wir uns verschiedener Typen sozialer Beziehungen, die prominent in der Debatte um globale Gerechtigkeit diskutiert werden: Mitgliedschaft, Kooperation, starke negative Auswirkungen (negative impact) und Macht. Die Bestimmung der Beziehung eines nicht-staatlichen Akteurs zu seinem sozialen Umfeld entlang dieser vier Kriterien ermöglicht es dann zu spezifizieren, wem gegenüber der Akteur Menschenrechtsverpflichtungen hat.

description: Recent years have shown steady progress in research towards molecular electronics [1,2], where molecules have been investigated as switches [3-5], diodes [6], and electronic mixers [7]. In much of the previous work a Scanning Tunnelling Microscope was employed to address an individual molecule. As this arrangement does not provide long-term stability, more recently metal-molecule-metal links have been made using break junction devices [8-10]. However, it has been difficult to establish unambiguously that a single molecule forms the contact [11]. Here, we show that a single H2 molecule can form a stable bridge between Pt electrodes. In contrast to results for other organic molecules, the bridge has a nearly perfect conductance of one quantum unit, carried by a single channel. The H2-bridge provides a simple test system and a fundamental step towards understanding transport properties of single-molecule devices.

description: Aims. We present the first three-dimensional internal motions for individual stars in the Draco dwarf spheroidal galaxy. Methods. By combining first-epoch $Hubble$ $Space$ $Telescope$ observations and second-epoch $Gaia$ Data Release 2 positions, we measured the proper motions of $149$ sources in the direction of Draco. We determined the line-of-sight velocities for a sub-sample of $81$ red giant branch stars using medium resolution spectra acquired with the DEIMOS spectrograph at the Keck II telescope. Altogether, this resulted in a final sample of $45$ Draco members with high-precision and accurate 3D motions, which we present as a table in this paper. Results. Based on this high-quality dataset, we determined the velocity dispersions at a projected distance of $\sim120$ pc from the centre of Draco to be $σ_{R} =11.0^{+2.1}_{-1.5}$ km/s, $σ_{T}=9.9^{+2.3}_{-3.1}$ km/s and $σ_{LOS}=9.0^{+1.1}_{-1.1}$ km/s in the projected radial, tangential, and line-of-sight directions. This results in a velocity anisotropy $β=0.25^{+0.47}_{-1.38}$ at $r \gtrsim120$ pc. Tighter constraints may be obtained using the spherical Jeans equations and assuming constant anisotropy and Navarro-Frenk-White (NFW) mass profiles, also based on the assumption that the 3D velocity dispersion should be lower than $\approx 1/3$ of the escape velocity of the system. In this case, we constrain the maximum circular velocity $V_{max}$ of Draco to be in the range of $10.2-17.0$ km/s. The corresponding mass range is in good agreement with previous estimates based on line-of-sight velocities only. Conclusions. Our Jeans modelling supports the case for a cuspy dark matter profile in this galaxy. Firmer conclusions may be drawn by applying more sophisticated models to this dataset and with new datasets from upcoming $Gaia$ releases.

description: Random matrix theory can be used to describe the transport properties of a chaotic quantum dot coupled to leads. In such a description, two approaches have been taken in the literature, considering either the Hamiltonian of the dot or its scattering matrix as the fundamental random quantity of the theory. In this paper, we calculate the first four moments of the distribution of the scattering matrix of a chaotic quantum dot with a time-dependent potential, thus establishing the foundations of a ``random scattering matrix approach'' for time-dependent scattering. We consider the limit that the number of channels $N$ coupling the quantum dot the reservoirs is large. In that limit, the scattering matrix distribution is almost Gaussian, with small non-Gaussian corrections. Our results reproduce and unify results for conductance and pumped current previously obtained in the Hamiltonian approach. We also discuss an application to current noise.

Gender, survival and self-respect: dimensions for agency for women within a poor rural Indo-Fijian community
Creators: name: Chattier, Priya D.
Publisher: name: The Australian National University
Year: 2008

description: The overall aim of this study is to outline the major methodological and conceptual challenges to understanding poverty in Fiji from a gender perspective. This study has sought to go beyond previous poverty approaches used in Fiji by examining poverty and intra-household relations using Sen's capability approach. I examine how Sen's capability approach can be used to study one core and overarching feminist concern, namely gender inequality and domestic power imbalances in the context of poverty and well-being evaluations. The thesis is divided into two interrelated parts. The first part is an exploration of Sen's capability approach with emphasis on intra-household relations and its implications for a theoretical framework on gender inequality. The second part ofthe thesis is about Indo-Fijian women's lived experiences of poverty and the ways in which these experiences denote gendered dynamics of survival, forming the basis on which to test my central concerns. The premise of my argument is that while women may experience gendered poverty as part of the capability failure, they never fail to utilise their agential capacities in their daily struggles of survival and fight against poverty and patriarchy. It is only through grounded analyses like this study that issues of agency can be meaningfully assessed, because it is only at that level that the context, content, and consequences of choice can be understood and interpreted. Women in traditional societies are likely to make choices which are essentially disempowering and also detrimental to their economic well-being. This is because deeply entrenched rules, norms and practices often influence women's behaviour, define values and shape their choices. The understanding of agency informing the capability approach in this research is qualified by being anchored within an institutional understanding of the conditions of choice (i.e. structures of constraint) and participant's situational accounts of choice and their agential capacities.
Adolescent masculinity, representation and transcendence
Creators: name: Chapman, Christopher Brent
Publisher: name: The Australian National University
Year: 2006

description: This thesis analyses representations of adolescent masculinity in Western culture in order to challenge normalised and restrictive discourses. It is a cross-disciplinary study which examines histories of the construction of adolescent masculinity with reference to sociological concepts of adolescence, to contemporary understandings of hegemonic masculine cultures, and to the visual representation of the adolescent male in art. Particular attention is paid to the symbolic visual representation of the adolescent male in the European iconographic history of Western art, and its implications of spiritual transcendence, and to the sociological construction of contemporary adolescent masculinity in relation to cultural discourses of the early twentieth century. The concept of transcendence is shown to be an animating trope of the representation of adolescent masculinity. Contemporary photographic and filmic art works by North American artists Larry Clark and Gus Van Sant are analysed in relation to these perspectives, and are found to engage complex and challenging articulations of adolescent masculinity, representation and transcendence. Clark's artist books of the 1990s, and his 2001 film Bully, are analysed in detail, and are found to offer important deconstructions of adolescent masculinity with reference to the physicalised adolescent male body, media­ generated imagery, and questions of violence and death. Van Sant's 2003 film Elephant, a fictionalised account of the 1999 Columbine High School shootings, is found to engage adolescent masculinity with. concepts of metaphysical and sociological transcendence. Theoretical perspectives on death and eroticism, normalising and heterotopic spatiality, and concepts of sacrifice are used as tools to engage analyses of Clark's and Van Sant's work. Issues of the sexualisation of the adolescent male body, the representation of male youth suicide and alternatives to hegemonic cultures of adolescent masculinity are discussed. The thesis concludes by appealing to compassionate and heterodox articulations of adolescent masculinity.

description: This thesis is an exploratory study, investigating the causes and mechanisms of categorisation problems in information systems. Looking at both cognitive functions in the brain and the context of information systems shows that categorisation is far from simple. Individuals vary so greatly as to make the design of a perfect categorisation scheme impossible. At the same time however, category structures in the mind are not arbitrary or random, and there are many commonalities between people. Hence a good categorisation scheme will find a balance between accommodating individual differences and encouraging conformity. The investigation process revealed a gap in the literature concerning assumptions about how to solve the problem. Most proposed solutions assume that an expert administrator is available to maintain category structures, that the items to be categorised will be primarily textual, and that the dataset will be very large. The reality is however, that these assumptions do not always hold true. This thesis proposes that by using tag clouds and clustering techniques, folksonomies can be adapted to suit smaller information systems where no dedicated administrator is available to maintain the category scheme. This was demonstrated through a number of experiments evaluating these approaches.

description: Gretl and R statistical libraries enables to perform data analysis using various algorithms, modules and functions. The case study of this research consists in geospatial analysis of the Mariana Trench, a hadal trench located in the Pacific Ocean. Technically, data modelling was performed using multi-functional combined approach of both Gretl and R libraries. The study aim is modelling and visualizing trends in the variations of the trench’s properties: bathymetry (depths), geomorphology (steepness gradient), geology, volcanism (igneous rocks). The workflow included following statistical methods computed and visualized by Gretl and R libraries: 1) descriptive statistics; 2) box plots, normality analysis by quantile-quantile (QQ) plots; 3) local weighted polynomial regression model (loess), 4) linear regression by several methods: weighted least squares (WLS) regression, ordinary least squares (OLS) regression, maximal likelihood linear regression and heteroskedasticity regression model; 5) confidence ellipses and marginal intervals for data distribution; 6) robust estimation by Nadaraya–Watson kernel regression fit; 7) correlation analysis and matrix. The results include following conclusions. First, the slope angle gradient has a correlation with the geological settings of the trench and distribution of volcanic igneous rocks. Second, the sediment thickness varies by the tectonic plates showing unequal distribution in space. Third, there is a correlation between the slope gradient and aspect degree. Forth, geospatial analysis of the bathymetry shows that the deepest part of the trench is located in the south-west.

description: The search for materials with novel and unusual electronic properties is at the heart of condensed matter physics as well as the basis to develop conceptual new technologies. In this context, the correlated honeycomb transition metal oxides attract large attention for both, being a possible experimental realization of the theoretically predicted magnetic Kitaev exchange and the theoretical prospect of topological nontriviality. The Mott insulating sodium iridate is prototypical among these materials with the promising prospect to bridge the field of strongly correlated systems with topology, finally opening a path to a wide band gap material with exotic surface properties. Here, we report a profound study of the electronic properties of ultra-high-vacuum cleaved surfaces combining transport measurements with scanning tunneling techniques, showing that multiple conductive channels with differing nature are simultaneously apparent in this material. Most importantly, a V-shaped density of states and a low sheet resistance, in spite of a large defect concentration, point towards a topologically protected surface conductivity contribution. By incorporating the issue of the addressability of electronic states in the tunneling process, we develop a framework connecting previous experimental results as well as theoretical considerations.
Lebesgue numbers and Atsuji spaces in subsystems of second order arithmetic

Subjects: subject: Logic (math.LO)

description: We study properties of complete separable metric spaces within the framework of subsystems of second order arithmetic. In particular we consider Lebesgue and Atsuji spaces. The former are those such that every open covering U has a Lebesgue number, i.e. a positive number q such that for every point x of the space, there exists an element of U which contains the ball of center x and radius q; the latter are those such that every continuous function into another complete separable metric space is uniformly continuous. The main results we obtain are the following: the statement "every compact space is Lebesgue" is equivalent to WKL_0; the statements "every perfect Lebesgue space is compact" and "every perfect Atsuji space is compact" are equivalent to ACA_0; the statement "every Lebesgue space is Atsuji" is provable in RCA_0; the statement "every Atsuji space is Lebesgue" is provable in ACA_0, but we do not know if it is equivalent to ACA_0. We also prove that the statement "the distance from a closed set is a continuous function" is equivalent to Pi^1_1-CA_0; the statements "there exists a complete separable metric space which is perfect and Heine-Borel compact (resp. Lebesgue, Atsuji)" are all equivalent to WKL_0.

description: Here, we explore the prospects of carrying out the single qubit spectroscopy of environmental noise when the resolution of the frequency filters produced by the dynamical decoupling pulse sequences can be set high enough to reveal the discrete structure of the noise spectral density. The standard form of spectroscopy is applicable when the filter is unable to resolve the discrete spectral lines and only coarse grained approximation of the spectrum is recorded in the qubit's decoherence rate. When the discrete structure becomes accessible, the qubit probe evolves in a qualitatively different manner, and the procedure for recovering spectral density has to be redesigned.

description: An algebra homomorphism $ψ$ from the q-deformed algebra $U_q({\rm iso}_2)$ with generating elements $I$, $T_1$, $T_2$ and defining relations $[I,T_2]_q=T_1$, $[T_1,I]_q=T_2$, $[T_2,T_1]_q=0$ (where $[A,B]_q=q^{1/2}AB-q^{-1/2}BA$) to the extension ${\hat U}_q({\rm m}_2)$ of the Hopf algebra $U_q({\rm m}_2)$ is constructed. The algebra $U_q({\rm iso}_2)$ at $q=1$ leads to the Lie algebra ${\rm iso}_2 \sim {\rm m}_2$ of the group ISO(2) of motions of the Euclidean plane. The Hopf algebra $U_q({\rm m}_2)$ is treated as a Hopf $q$-deformation of the universal enveloping algebra of ${\rm iso}_2$ and is well-known in the literature. Not all irreducible representations of $U_q({\rm m}_2)$ can be extended to representations of the extension ${\hat U}_q({\rm m}_2)$. Composing the homomorphism $ψ$ with irreducible representations of ${\hat U}_q({\rm m}_2)$ we obtain representations of $U_q({\rm iso}_2)$. Not all of these representations of $U_q({\rm iso}_2)$ are irreducible. The reducible representations of $U_q({\rm iso}_2)$ are decomposed into irreducible components. In this way we obtain all irreducible representations of $U_q({\rm iso}_2)$ when $q$ is not a root of unity. A part of these representations turns into irreducible representations of the Lie algebra iso$_2$ when $q\to 1$. Representations of the other part have no classical analogue.

 Material examined. – LSUHC 7853: Che Teal Chrum, 8 Aug.2006.
 Remarks. – A broken tail was recovered from a mis-capture of a specimen 2 m up on the side of a tree in the forested area surrounding Che Teal Chrum Village. It is identified as belonging to Hemidactylus platyurus (fide Carranza & Arnold, 2006) and not H. craspedotus in that the fringe on the tail is one-quarter the width of the body of the tail whereas in H. craspedotus the fringe is equal to the width of the body of the tail. The morphology of LSUHC 7853 matches that of the tails of LSUHC 7323–24 from the northeastern Cardamoms and additional material from West Malaysia (LSUHC 3874, 5564, 6430, 6636, 6732, 7146, 8230). The tail was compared to the tails of seven H. craspedotus, (LSUHC 4754, 5080–81, 5613, 6316, 6330, 6672) from West Malaysia.

description: The International Maritime Organization (IMO) is working on adopting a greenhouse gas (GHG) emissions pricing mechanism to drive the decarbonization of international shipping. This chapter analyzes key reasons why the GHG pricing mechanism remains one of the most contentious points of debate in the negotiations. The chapter highlights that GHG pricing mechanisms can be used to achieve different aims (e.g., flexibility, emissions reductions, revenue raising). Differences in proposals under consideration at the IMO seem based at least in part on a preference for one aim over another. These differences in views on what GHG pricing should aim to achieve seem to be at the core of the disagreement between states. In addition, there are various (potential) challenges related to implementing an IMO GHG pricing mechanism. This chapter looks at both legal (compatibility with MARPOL and WTO law) and non-legal challenges (e.g., impacts on states, revenue use, and the availability of alternative fuels) and discusses some potential ways forward.

description: We have performed self-consistent calculations of the nonlinear screening of a point charge Z in a two-dimensional electron gas using a density functional theory method. We find that the screened potential for a Z=1 charge supports a bound state even in the high density limit where one might expect perturbation theory to apply. To explain this behaviour, we prove a theorem to show that the results of linear response theory are in fact correct even though bound states exist.
