description: We report a detailed study of tunneling spectra measured on 2H-Ta$_x$Nb$_{1-x}$Se$_2$ ($x=0\sim 0.1$) single crystals using a low-temperature scanning tunneling microscope. The prominent gap-like feature unintelligible for a long time was found to be accompanied by some "in-gap" fine structures. By investigating the second-derivative spectra and their temperature and magnetic field dependencies, we were able to prove that inelastic electron tunneling is the origin of these features and obtain the Eliashberg function of 2H-Ta$_x$Nb$_{1-x}$Se$_2$ at atomic scale, providing a potential way to study the local Eliashberg function and phonon spectra of the related transition-metal dichalcogenides.

description: We discuss the link between string backgrounds and the associated world-sheet CFTs. In the search for new backgrounds and CFTs, Penrose limits and Lie algebra contractions are important tools. The Nappi-Witten construction and the recently discovered logarithmic CFT by Bakas and Sfetsos, are considered as illustrations. We also speculate on possible extensions.

title: Occupational choice for girls: a sociological study of the constraints on the routes taken by a small group of girls in a college of further education
Creators: name: Sherratt, Norma Margaret
Publisher: name: The Open University
Year: 1982

description: Any explanation of the routes girls take into employment or further/higher education (routes generally leading to the female sector of the labour force) must involve consideration of the constraints on any choices they make, the relationship between objective constraints and those stemming from their own aspirations, and the different forms taken by constraints according to class and ability divisions. The aim of this work is to trace the careers, in both the objective and subjective senses, of a group of girls as they make educational/occupational choices, in order to gain a greater understanding of these constraints. And it is shown that, in this case, of a group of sixteen-seventeen year olds just starting general GCE courses at a college of further education, whilst the eventual entry of all into female areas of employment can be understood as a product, primarily, of past experiences in the school and the family, the eventual entry of the majority into "dead end" female areas of employment, in contrast to those few who entered training for a "career", is best understood as the product of a process of "opting out" of education without any great increase in qualifications. And it is suggested that this is due primarily to the interaction between awareness of objective constraints and a central life interest of "glamour". It is the modification of a subjective career dominated by notions of "having a career" to one in which, in response to a realisation of how long and difficult and boring it will be to maintain this aim, some form of displacement of occupational careers takes place, which forms the centre of the analysis. And the report concludes by suggesting the relevance of the concept of a "glamorous" career to any discussion of feminine careers; and in particular to any attempt to understand the routes taken by girls for whom neither "domestic" careers nor "occupational" careers seem adequate conceptualisations.

description: Typically, drug discrimination is examined within the context of operant conditioning (cf. Stolerman & Shine, 1985). In such designs, one behavior is reinforced during sessions preceded by an injection of a drug and a second behavior is reinforced by an injection of the drug vehicle. The discrimination is evidenced by differential responding in the presence and absence of the drug stimulus. In the present series of experiments, an alternative procedure for assessment of drug-discrimination learning was examined, i.e., conditioned-taste aversion learning (cf. Riley & Tuck, 1985). In conditioned taste-aversion learning, an animal is injected with a toxin following consumption of a novel taste. In such a design, animals avoid consumption of that taste on subsequent exposures. The question posed in the present series of experiments was whether an aversion to a taste would be acquired and displayed in one specific drug state, while the same taste would be consumed in another drug condition. Prior to assessing drug-discrimination learning within the taste-aversion design, a dose of a drug had to be chosen that had no potential for supporting conditioning itself (Experiment 1), no unconditioned suppressant effects on consumption (Experiment 2), and was able to serve as a discriminative stimulus in an operant paradigm (Experiment 3). Based on the results of the first three experiments, a dose of 1.8 mg/kg of phencyclidine was chosen to determine if the taste-aversion design could serve as a baseline for drug-discrimination learning. In Experiment 4, different groups of rats were trained in a conditioned taste-aversion paradigm with either the presence or absence of PCP as a signal for a saccharin-LiCl pairing. Specifically, for Group P-L on days when PCP was injected 10 min prior to saccharin presentation, LiCl was injected immediately following saccharin access. On days when distilled water was injected 10 min prior to saccharin presentation, however, no LiCl was injected. For Group W-L, these conditions were reversed. Differential consumption in the presence or absence of the drug stimulus emerged after three conditioning trials. In addition, substituting different doses of PCP produced a generalization gradient around the training dose. The rapid control acquired by the drug stimulus in this procedure and the absence of any other confounding stimuli, e.g., a reinforcing stimulus, suggest that the conditioned taste-aversion design may be an efficient method for classifying drugs on the basis of their discriminative stimulus properties.

description: We investigate the impacts of combination of fermion-fermion interactions and impurity scatterings on the low-energy stabilities of two-dimensional asymmetric materials with a quadratic band crossing point by virtue of the renormalization group that allows us to treat distinct sorts of physical ingredients on the same footing. The coupled flow evolutions of all interaction parameters which carry the central physical information are derived by taking into account one-loop corrections. Several intriguing results are manifestly extracted from these entangled evolutions. At first, we realize that the quadratic band touching structure is particularly robust once the fermionic couplings flow toward the Gaussian fixed point. Otherwise, it can either be stable or broken down against the impurity scattering in the vicinity of nontrivial fixed points. In addition, we figure out two parameters $η$ and $λ$ that measure rotational and particle-hole asymmetries are closely energy-dependent and exhibit considerably abundant behaviors depending upon the fates of fermion-fermion couplings and different types of impurities. Incidentally, as both $η$ and $λ$ can be remarkably increased or heavily reduced in the low-energy regime, an asymmetric system under certain restricted conditions exhibits an interesting phenomenon in which transitions either from rotational or particle-hole asymmetry to symmetric situation would be activated.

description: This study is chiefly concerned with the impact of commonly employed variations in the specification of econometric models on the outcome of those models. Three previously published simple time series models of the determinants of coal mine fatality and injury rates are replicated. By varying such factors as the definition of the dependent variables, the manner of operationalization of the concepts which serve as the independent variables, the time period modeled, and the presence of trend terms, nearly 3,000 unique model specifications are developed and comparatively evaluated. The results suggest the following: (1) scholars have traditionally paid too little attention to the impact of alternate measures of concepts on model outcome; (2) the published literature fails to deal adequately with the deleterious effects of collinearity on model outcomes; (3) studies purporting to test micro-level theories often commit ecological fallacies by analyzing macro-level data; (4) the simple time series econometric technique may have much more limited utility than has generally been assumed due to its tendency to be massively unstable contingent on even minor changes in model specification; (5) sensitivity analysis is an important and under-utilized tool which has great potential to improve the quality of social science research. Included are reviews of the background and context of coal mine safety regulation, a review of the literature from related fields of study, and an analysis of the theoretical issues of interest. Particular emphasis is put upon contrasting the predictions of economic theory and a behavioral approach, although no clear test of the two approaches is included. There is also an extensive review of the methodological issues which are relevant to least squares regression analysis.

description: Einstein-Cartan theory is an extension of the standard formulation of General Relativity characterized by a non-vanishing torsion. The latter is sourced by the matter fields via the spin tensor, and its effects are expected to be important at very high spin densities. In this work we analyze in detail the physics of Einstein-Cartan theory with Dirac and Maxwell fields minimally coupled to the spacetime torsion. This breaks the $U(1)$ gauge symmetry, which is suggested by the possibility of a torsion-induced phase transition in the early Universe. The resulting Dirac-like and Maxwell-like equations are non-linear with self-interactions as well as having fermion-boson non-minimal couplings. We discuss several cosmological aspects of this theory, including bounces, acceleration phases and matter-antimatter asymmetry in the torsion era, as well as late-time effects such as the generation of an effective cosmological constant, dark energy, and future bounces within cyclic solutions.

AN ANALYSIS OF FOREIGN TRADE AND INDUSTRIAL GROWTH IN IRAN, 1963-1973 (IMPORT, COMMERCIAL POLICY)
Creators: name: Bahreini, Mohammad Hossein
Publisher: name: American University
Year: 2023

description: This study attempts to evaluate foreign trade policies of the Iranian government since the early 1960s in relation to the growth of manufacturing and the performance of the country's imports and exports. More specifically, the investigation is intended to show that the 1960s import-substitution policy of the Iranian government failed to achieve its objective of greater industrial self-sufficiency, and indeed, was also associated with the poor performance of non-oil exports. After a detailed analysis of the implemented policies, the relative contributions of the growth of manufacturing sector in the growth of GNP and the import dependence of the protected industrial sector are examined. It is found that the growth rate of GNP during the period under investigation, rather than reflecting the growth rate of the protected manufacturing sector, was mainly the result of the growth of its two other components: oil and services. In fact given the enormous amount of investments in manufacturing, the contribution of this sector in the growth of GNP is found to be unimpressive. The poor performance of the agricultural sector also is demonstrated. The performance of imports is studied to show that the growth of "domestic" production of industrial products in Iran, was a reflection of the growth of "foreign" sources of raw materials and intermediate goods. Such "import dependence" on the part of the protected manufacturing sector tended to increase over time. Moreover, the imports of consumer goods also tended to increase in spite of the massive increases in the imports of the primary and intermediate goods required for the production of the protected assembly plants. The performance of exports is studied in the context of the balance-of-payments tables. The negative effects of the adopted import-substitution policies on the growth of non-oil exports are demonstrated.
Primordial bubbles of colour superconducting quark matter

description: We analyze the possibility that bubbles of quark matter surviving the confinement phase transition might have become colour superconducting due to the enormous compression suffered by them. Because of the relatively high temperature of the process we compare the initially unpaired quark matter with the colour-flavour locked alternative when the extremely large chemical potential could have increased the critical temperature sufficiently and find that this latter phase would be more stable before the bubble compression stops. If other physical effects have not affected completely their stability, these bubbles might still exist today and perhaps be observed as strangelets.

title: Nuclear magnetic resonance studies in solids containing dipolar coupled spin-half species.
Creators: name: Apperley, David Charles
Publisher: name: The Open University
Year: 1986

description: Closed analytical expressions for the NMR response to various pulse sequences for small, isolated heteronuclear spin systems containing dipolar coupled spin-half nuclei are derived and discussed. In particular, the responses of single crystal and polycrystalline assemblies of two, three and four spin systems to single, strong, resonant rf pulses and Py(90°)-T-P (8) pulse sequences are considered. The calculations are carried out using the density matrix formulism. The results of the moment expansion for the treatment of a general multi-spin system are included for comparison. The calculated response to one pulse (the FID) is compared to the experimentally observed FID for potassium hydrogen difluoride, caesium hydrogen difluoride and sodium fluoroethanoate. The calculated response to a two pulse sequence is compared to the experimentally observed response for KHF2. It is shown that the expressions for the responses to two pulse sequences can, in general, be decomposed into three components: an FID component, an echo component and a cross-term component. The effect that these components have on observed spin echoes is discussed for model systems. It is demonstrated that the separation of homonuclear and heteronuclear interactions using spin echo techniques is not as straightforward as has previously been suggested. The predictions of the operator formulism often used in spin echo studies are shown to be of limited value. Finally, a general treatment of nuclear spin relaxation in heteronuclear spin systems is given. Two specific motional models are included: (i) a three spin, two site model and (ii) a four spin, two site model. A generalisation of the former model is also included. These models are used to interpret the spin-lattice relaxation behaviour of both polycrystalline KHF2 and CsHF2. The results of the study of the latter compound differ in several aspects from those previously reported.
An investigation into evaluating laptop PCs using TBL : an economic view

description: The following report is an investigation into the laptop computer usage by faculty and staff at UBC including an evaluation using the accounting concept of the triple bottom line (TBL) assessment. The TBL assessment consists of evaluations of social, environmental and economic impacts on the purchase of laptop PCs to replace the existing ones currently in use at the university. This portion of the report examines the economic view of the TBL and will be considered alongside separate reports on the social and environmental aspects. Based on data provided by the stakeholders regarding the current laptop use on campus, a sample set of laptops to be examined was researched into as part of constructing a price vs. performance ratio. The ratio would simplify the process of evaluation for the user to make more informed decisions when purchasing a laptop PC incorporated into an easy-to-understand scoring index. This index addresses the various performance and functionality components of a laptop PC that should be considered when evaluating the relevance of a laptop PC to meet the needs of a particular user. Constructing the scoring index began with research into methods previously used to evaluate laptop PCs based on performance and benchmark ratings. Next, a database of possible laptop PCs that may be adopted on campus was created with detailed technical information for each model type. Next, after further research, an equation resulting in an overall rating for a particular model was created considering the various components that affect the purchase of a laptop PC depending on the user such as benchmark rating, screen size and memory size, among others. Although the department purchases the laptops from on campus vendors, the information collected to prepare a price vs. performance ratio was collected directly from the manufacturers. The index is created with two specific users in mind: a basic user and a power user; where the power user is expected to have higher performance demands than the basic user.

description: Electron transfer to an individual quantum dot promotes the formation of charged excitons with enhanced recombination pathways and reduced lifetimes. Excitons with only one or two extra charges have been observed and exploited for very efficient lasing or single quantum dot LEDs. Here, by room-temperature time-resolved experiments on individual giant-shell CdSe/CdS quantum dots, we show the electrochemical formation of highly charged excitons containing more than twelve electrons and one hole. We report the control over intensity blinking, along with a deterministic manipulation of quantum dot photodynamics, with an observed 210-fold increase of the decay rate, accompanied by 12-fold decrease of the emission intensity, while preserving single-photon emission characteristics. These results pave the way for deterministic control over the charge state, and room-temperature decay-rate engineering for colloidal quantum dot-based classical and quantum communication technologies.

description: The time-varying density of D-branes and anti-D-branes in an expanding universe is calculated. The D-brane anti-brane annihilation rate is shown to be too small to compete with the expansion rate of a FRW type universe and the branes over-close the universe. This brane problem is analogous to the old monopole problem. Interestingly however, it is shown that small dimension D-branes annihilate more slowly than high dimension branes. Hence, an initially brany universe may be filled with only low dimension branes at late times. When combined with an appropriate late inflationary theory this leads to an attractive dynamical way to create a realistic braneworld scenario.

Trenchard and Gordon collaborated in the writing and publishing of The Independent Whig and Cato's Letters, weekly essays that first appeared in the London press for almost four years in the early 1720s, with "a View to the Quiet and Stability of this Free State." The assiduous inculcation, by High Churchmen, of doctrines antithetical to the security of English Protestantism in the House of Hanover and seditious High-Tory exploitation of popular discontents deeply disturbed Trenchard and Gordon. As "Cato" and "the Independent Whig," they sought to secure the constitutionally limited English monarchy in the recently established, Protestant House of Hanover against a popular High-Tory Church party whose propaganda and agitation threatened the destruction of political and religious liberty with the Stuart restoration High Tories desired. The authors of The Independent Whig and Cato's Letters combatted High-Tory doctrines and methods. As Independents they challenged High-Church politico-religious orthodoxy in order to vitiate the Anglican lower clergy's capacity to destabilize society with treasonable, "popish" dogma. As "Cato" and convinced that High Tories manipulated popular discontents to serve Jacobite aims, Trenchard and Gordon instructed the King and his Whig ministry to fully redress grievances. "Cato" took up the people's cause against the corruption surrounding the South Sea crisis and made a concerted effort to lead popular discontents down loyal, legal paths and deter what "Cato" considered the seditious political ploys of High Tories who merely exploited libertarian rhetoric to serve the Stuart cause. Trenchard and Gordon publicly propagated Lockean political and religious principles when contractarianism, natural rights, and resistance theory remained anathema and most Whigs would not publicly espouse them. John Trenchard and Thomas Gordon wrote as concerned, Hanoverian loyalists. They provided a libertarian defense of the Protestant religion and the limited English monarchy in the House of Hanover against High-Tory counterrevolution and counterreformation.
Geodesic Nucleation and Evolution of a de Sitter Brane

description: Within the framework of Geodesic Brane Gravity, the deviation from General Relativity is parameterized by the conserved bulk energy. The corresponding geodesic evolution/nucleation of a de-Sitter brane is shown to be exclusively driven by a double-well Higgs potential, rather than by a plain cosmological constant. The (hairy) horizon serves then as the locus of unbroken $Z_{2}$ symmetry. The quartic structure of the scalar potential, singled out on finiteness grounds of the total (including the dark component) energy density, chooses the Hartle-Hawking no-boundary proposal.

THE RELATIONSHIP BETWEEN ATTRACTIVENESS AND SELF-ESTEEM: A TEST OF THE DISCOUNTING HYPOTHESIS
Creators: name: Rowan, Jeffrey Lawrence
Publisher: name: American University
Year: 2023

description: Sixty-four male and female subjects were rated on physical attractiveness by outside observers, and simultaneously asked to rate themselves. Subjects were then asked to write a brief essay on a current topic, after which all received written praise from a fictitious reader. Half the subjects believed that they had been seen by the reader, while half did not. Subjects then were asked to give their impressions of the feedback received and of the person who had rendered the praise. Contrary to hypothesis, those subjects rated as high-attractive by outsiders did not show greater skepticism about the praise when they thought they had been seen by the reader. However, females who had rated themselves as high-attractive did tend to discount praise when they thought they had been seen; self-rated attractive males, in contrast, showed greater belief in the praise when they thought they had been seen. In comparing external ratings of subjects' attractiveness with subjects' self-ratings, the correlation approached zero. The implications of these findings for the "discounting hypothesis" are discussed.

QFT and topology in two dimensions: $SL(2,{\Bbb R})$-symmetry and the de Sitter universe

description: We study bosonic Quantum Field Theory on the double covering $\widetilde{dS}_{2}$ of the 2-dimensional de Sitter universe, identified to a coset space of the group $SL(2,{\Bbb R})$. The latter acts effectively on $\widetilde{dS}_{2}$ and can be interpreted as it relativity group. The manifold is locally identical to the standard the Sitter spacetime ${dS}_2$; it is globally hyperbolic, geodesically complete and an inertial observer sees exactly the same bifurcate Killing horizons as in the standard one-sheeted case. The different global Lorentzian structure causes however drastic differences between the two models. We classify all the $SL(2,{\Bbb R})$-inveriant two-point functions and show that: 1) there is no Hawking-Gibbons temperature; 2) there is no covariant field theory solving the Klein-Gordon equation with mass less than $1/2R$ , i.e. the complementary fields go away.

Topological Weaire-Thorpe models of amorphous matter

description: Amorphous solids remain outside of the classification and systematic discovery of new topological materials, partially due to the lack of realistic models that are analytically tractable. Here we introduce the topological Weaire-Thorpe class of models, which are defined on amorphous lattices with fixed coordination number, a realistic feature of covalently bonded amorphous solids. Their short-range properties allow us to analytically predict spectral gaps. Their symmetry under permutation of orbitals allows us to analytically compute topological phase diagrams, which determine quantized observables like circular dichroism, by introducing symmetry indicators for the first time in amorphous systems. These models and our procedures to define invariants are generalizable to higher coordination number and dimensions, opening a route towards a complete classification of amorphous topological states in real space using quasilocal properties.
