The Assessment of Reading for English Learners in the Academic Language of Mathematics
Creators: name: Nigolian, Mark
Publisher: name: University of Leicester
Year: 2022
Subjects: Uncategorized

description: This thesis was designed to improve the assessment of math academic language, specifically in the area of reading for English Language Learners (ELLs) in grades K-12 in the United States (U.S.). This was conducted through research on the WIDA (World-class Instructional Design and Assessment) Consortium’s approach in assessing academic language in math reading. The research also developed a new method for assessing reading in math academic language based on Systemic Functional Linguistics called the REALM (Reading Evaluation in the Academic Language of Mathematics).Part 1 of this thesis used a Mixed Methods Research (MMR) to evaluate WIDA math reading test items. A core component of this research was an item analysis comparing the performance of ELLs who possess math knowledge of the math topics embedded on the WIDA ELP test items to the performance of those ELLs without such math knowledge. Other elements of the MMR were a cognitive lab asking student perceptions of WIDA math reading items, a teacher survey measuring teacher perceptions about the presence of math content in WIDA items, and text analysis of WIDA items. Part 1 showed that content knowledge in mathematics may impact student performance on the WIDA math reading items, intended to measure language proficiency.Part 2 of the thesis research developed, refined, and administered a math reading assessment (REALM) focused on math word problems based on Systemic Functional Linguistics (SFL). This new math language assessment operated effectively and provided detailed information regarding student needs and strengths in the area of reading math word problems. The transparent nature of the REALM was designed to support students in understanding the language features of math word problems to enhance language and math learning.

description: We document a new empirical finding in the foreign exchange market: currency returns show systematic reversals around the benchmark fixings. Specifically, the US dollar, on average, appreciates in the hours before fixes and depreciates after fixes.

description: Nous mettons en lumière un nouveau résultat empirique concernant le marché des changes : les rendements qui y sont dégagés connaissent systématiquement un mouvement d’inversion autour du moment où les taux de référence sont établis. Plus précisément, on remarque que, en moyenne, le dollar américain s’apprécie au cours des heures précédant l’établissement des taux de référence et qu’il se déprécie après.

description: This short note presents a new relation between coherent spaces and finiteness spaces. This takes the form of a functor from COH to FIN commuting with the additive and multiplicative structure of linear logic. What makes this correspondence possible and conceptually interesting is the use of the infinite Ramsey theorem. Along the way, the question of the cardinality of the collection of finiteness spaces on N is answered. Basic knowledge about coherent spaces and finiteness spaces is assumed.

description: We analyse a novel squeezing and entangling mechanism which is due to correlated Stokes and anti-Stokes photon forward scattering in a multi-level atom vapour. Following the proposal we present an experimental demonstration of 3.5 dB pulsed frequency nondegenerate squeezed (quadrature entangled) state of light using room temperature caesium vapour. The source is very robust and requires only a few milliwatts of laser power. The squeezed state is generated in the same spatial mode as the local oscillator and in a single temporal mode. The two entangled modes are separated by twice the Zeeman frequency of the vapour which can be widely tuned. The narrow-band squeezed light generated near an atomic resonance can be directly used for atom-based quantum information protocols. Its single temporal mode characteristics make it a promising resource for quantum information processing.

description: Excerpts from the report: As in many other wheat-producing areas, stubble mulching has been found by research and experience to be one of the simplest and most effective management practices to protect land from erosion. Residues from the last crop are used as a mulch, held to the land by standing stubble, to conserve moisture and to prevent the soil from washing or blowing away ; thus the term "stubble mulching." This bulletin describes the machinery, and the sequence and methods of operation that have been found best for stubble-mulch farming in the Pacific Northwest wheat areas. Although directed primarily toward solution of erosion problems in that area, the information is applicable, wholly or in part, to other areas in the West where similar problems are encountered.

description: Man könnte Lisa Sinan eine fahrende Künstlerin nennen. Ihre Werke bestehen aus unterschiedlichen Materialien, Stoffen, Farben und Dingen, die sie in ihrem Auto transportiert und erst vor Ort zu großen Installationen verbindet. Dieses methodische Vorgehen gleicht einem ungeplanten Umzug in ein Museumszimmer, in dem Sinan site specific wieder und wieder auf die Architekturen reagieren muss – ohne das Atelier als sichere Probebühne.Ihre Arbeiten zeichnet ein sicheres Empfinden für Farben und Form aus. Mit genauer Beobachtungsgabe spielt sie in vermeintlicher Simplizität mit den Grenzen bildhauerischer Fiktion. Durch additive Verfahren wird der vorhandene Raum in Türme und Burggräben verwandelt, heimlich verdoppelt sich eine Säule, farblich wird die Ausgangsarchitektur akzentuiert und kommentiert. In anderen Werken versteckt Sinan Reales, unter der brauen Zeltplane oder hinter dem Sichtschutz des Setzkastens. In einer Installation aus 2018 folgen wir ihr auf den Balkon mit Geländer um schließlich festzustellen, dass unser Ausblick durch den weißen Leinwandstoff verhindert wird.Neben der klugen und prägnanten Formensprache weisen ihre Arbeiten auch einen hohen persönlichen Anteil auf. Die Titel, verwendete Sounds oder kleine Details geben einen Einblick in einen ganz eigenen Humor, mit dem die Künstlerin Räume erschafft, in denen sie selbst viele Stunden lang während des Aufbaus gelebt und gearbeitet hat. Das verwendete Material stammt aus dem eigenen Fundus, bestimmte Motive wie das Geländer kehren immer wieder. Biografische Beziehungen schimmern durch diese Arbeiten und geben ihnen neben aller Experimentalität eine Zugänglichkeit ohne ins Bekenntnishafte abzurutschen: Lisa Sinans Kunst ist lebendig, aber nicht privat.von Svenja Reiner

Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: We measure the flux of spherical glass beads through a hole as a systematic function of both tilt angle and hole diameter, for two different size beads. The discharge increases with hole diameter in accord with the Beverloo relation for both horizontal and vertical holes, but in the latter case with a larger small-hole cutoff. For large holes the flux decreases linearly in cosine of the tilt angle, vanishing smoothly somewhat below the angle of repose. For small holes it vanishes abruptly at a smaller angle. The conditions for zero flux are discussed in the context of a {\it clogging phase diagram} of flow state vs tilt angle and ratio of hole to grain size.

description: This work verifies the principle that gravitation is caused by {\it energy} and not simply by mass alone. A model is proposed in which cosmic ray protons flow radially through the galaxy. The resulting electric field energy creates a gravitational force, in addition to the conventional Newtonian force. The model yields a rotation curve that agrees in detail with the experimental curve. The total electric field energy is calculated. It is the missing mass of the galaxy.

description: We use very deep near-infrared (NIR) imaging data obtained in MOIRCS Deep Survey (MODS) to investigate the evolution of the galaxy stellar mass function back to z~3. The MODS data reach J=24.2, H=23.1, K=23.1 (5sigma, Vega magnitude) over 103 arcmin^2 (wide) and J=25.1, H=23.7, K=24.1 over 28 arcmin^2 (deep) in the GOODS-North region. The wide and very deep NIR data allow us to measure the number density of galaxies down to low stellar mass (10^9-10^10 Msun) even at high redshift with high statistical accuracy. The normalization of the mass function decreases with redshift and the integrated stellar mass density becomes ~ 8-18% of the local value at z~2 and ~ 4-9% at z~3, which are consistent with results of previous studies in general fields. Furthermore, we found that the low-mass slope becomes steeper with redshift from alpha ~- 1.3 at z~1 to alpha ~- 1.6 at z~3, and that the evolution of the number density of low-mass (10^9-10^10 Msun) galaxies is weaker than that of M* (~10^11 Msun) galaxies. This indicates that the contribution of low-mass galaxies to the total stellar mass density has been significant at high redshift. The steepening of the low-mass slope with redshift is opposite trend expected from the stellar mass dependence of the specific star formation rate reported in previous studies. The present result suggests that the hierarchical merging process overwhelmed the effect of the stellar mass growth by star formation and was very important for the stellar mass assembly of these galaxies at 1

description: We introduce detector-level entanglement, a unified entanglement concept for identical particles that takes into account the possible deletion of many-particle which-way information through the detection process. The concept implies a measure for the effective indistinguishability of the particles, which is controlled by the measurement setup and which quantifies the extent to which the (anti-)symmetrization of the wave-function impacts on physical observables. Initially indistinguishable particles can gain or loose entanglement on their transition to distinguishability, and their quantum statistical behavior depends on their initial entanglement. Our results show that entanglement cannot be attributed to a state of identical particles alone, but that the detection process has to be incorporated in the analysis.

description: Excerpts from the report: Beginning in 1946, fiber and spinning tests had been published annually on modal qualities of American cottons. This seemed a good beginning, and it was therefore decided to assemble and analyze the results of these and other large studies regularly made in the Cotton Division [Agricultural Marketing Service] since 1946. It is this material, assembled primarily to provide a basis for a better understanding of cotton quality relationships in our own work, that is presented in this report and supplement. The analyses in this report are based on three sets of studies made in the Cotton Division: on test results for composited samples of modal qualities of American upland cottons included in crops included in the annual quality surveys, crops of 1956-58; and on samples from individual bales purchased for use in grade or staple standards since 1956.

description: In the framework of the topcolor-assisted technicolor ($TC2$) model and the littlest Higgs model with $T$-parity ($LHT$ model), we consider the rare B decays $B\to Mν\barν$ with $M=π,K,ρ,$ or $K^{\ast}$. We find that the contributions of the $TC2$ model to the branching ratios of these decay processes are larger than those for the $LHT$ model. The experimental upper limits for some branching ratios can give severe constraints on the free parameters of the $TC2$ model.

description: We perform fully dynamical simulations at small quark masses by reweighting in the quark mass, calculating the weight factors stochastically. This approach avoids some of the technical difficulties associated with direct simulations. We find that the weight factors fluctuate only moderately on nHYP smeared dynamical Wilson-clover ensembles, and demonstrate that the overlap between the original and reweighted configurations is large both for short and long distance observables. We could successfully reweight 16^4, (1.85fm)^4 volume configurations from m_q 20 MeV to m_q~5 MeV, and 24^4, (2.77fm)^4 configurations from m_q~8MeV to m_q~MeV quark masses, reaching the epsilon-regime. Using the pseudoscalar and axialvector correlators we predict the low energy constants Sigma and F and study their volume and mass dependence.

description: Excerpts from the report Introduction: This is one of a series of annual reports containing information on fiber characteristics and spinning performance of cotton from all major commercial production areas of the United States. The annual quality surveys are designed to facilitate planned production and orderly marketing of cotton. The data provide farmers and breeders with basic quality information of cottons produced under field conditions, and help cotton merchants and manufacturers locate sources of cotton having fiber characteristics and spinning performance desired for specific end uses. The surveys also provide historical data for use in studying the relationships between various fiber property measurements and processing performance.

Biosynthesis of pyocyanine
Creators: name: Ingledew, Michael William
Publisher: name: University of British Columbia
Year: 2011

description: A new medium for the production of the phenazine pigment pyocyanine by Pseudomonas aeruginosa has been developed. This medium contains 2-ketogluconate as the sole carbon source and allows rapid synthesis of pyocyanine in yields which are proportional to the carbon added. The availability of this new resuspension medium and the isolation of a mutant of P. aeruginosa unable to oxidize shikimic acid, quinic acid, and some other compounds related to the aromatic pathway, has facilitated the evaluation of components of this pathway as precursors to pigment. Using the competition technique and direct incorporation of ¹⁴C, shikimic acid has been shown to account for virtually 100% of the carbon atoms required for the phenazine nucleus of pyocyanine, implicating the branch point of synthesis of the pigment as occurring at this level of the aromatic pathway. Quinic acid competed only by virtue of its conversion by quinic dehydrogenase and biosynthetic enzymes, to shikimate. These observations were confirmed utilizing polyauxotrophic mutants which were unable to synthesize pyocyanine until quinate or shikimate were supplied. The involvement of a permease for the concentration of hydroaromatics intracellularly has been demonstrated. Attempts at the isolation of postulated N-containing derivatives involved in "dimerization" to form pyocyanine have only met with limited success.

description: We observed SAX J1808.4-3658 (1808), the first accreting millisecond pulsar, in deep quiescence with XMM-Newton and (near-simultaneously) Gemini-South. The X-ray spectrum of 1808 is similar to that observed in quiescence in 2001 and 2006, describable by an absorbed power-law with photon index 1.74+-0.11 and unabsorbed X-ray luminosity L_X=7.9+-0.7*10^{31} ergs/s, for N_H=1.3*10^{21} cm^{-2}. Fitting all the quiescent XMM-Newton X-ray spectra with a power-law, we constrain any thermally emitting neutron star with a hydrogen atmosphere to have a temperature less than 30 eV and L_{NS}(0.01-10 keV)<6.2*10^{30} ergs/s. A thermal plasma model also gives an acceptable fit to the continuum. Adding a neutron star component to the plasma model produces less stringent constraints on the neutron star; a temperature of 36^{+4}_{-8} eV and L_{NS}(0.01-10 keV)=1.3^{+0.6}_{-0.8}*10^{31} ergs/s. In the framework of the current theory of neutron star heating and cooling, the constraints on the thermal luminosity of 1808 and 1H 1905+000 require strongly enhanced cooling in the cores of these neutron stars. We compile data from the literature on the mass transfer rates and quiescent thermal flux of the largest possible sample of transient neutron star LMXBs. We identify a thermal component in the quiescent spectrum of the accreting millisecond pulsar IGR J00291+5934, which is consistent with the standard cooling model. The contrast between the cooling rates of IGR J00291+5934 and 1808 suggests that 1808 may have a significantly larger mass. This can be interpreted as arising from differences in the binary evolution history or initial neutron star mass in these otherwise similar systems.

description: Excerpts from the report: The watermelon is a native of semidesert regions of tropical Africa. It is sensitive to frost and is most productive where there is a long, warm, growing season. In the 1950's, about 90 percent of the watermelon acreage of the United States was in the Southern and Southwestern States and California. Watermelon shipments begin in late spring from Florida and California. Shipments follow in early summer from Texas, Georgia, South Carolina, most of the other Southern States, and California. In late summer watermelons are marketed from the Central and Middle Atlantic States. The season ends about October 1.

description: We study the reduced fidelity susceptibility $χ_{r}$ for an $M$-body subsystem of an $N$-body Lipkin-Meshkov-Glick model with $τ=M/N$ fixed. The reduced fidelity susceptibility can be viewed as the response of subsystem to a certain parameter. In noncritical region, the inner correlation of the system is weak, and $χ_{r}$ behaves similar with the global fidelity susceptibility $χ_{g}$, the ratio $η=χ_{r}/χ_{g}$ depends on $τ$ but not $N$. However, at the critical point, the inner correlation tends to be divergent, then we find $χ_{r}$ approaches $χ_{g}$ with the increasing the $N$, and $η=1$ in the thermodynamic limit. The analytical predictions are perfect agreement with the numerical results.

description: From sand piles to electrons in metals, one of the greatest challenges in modern physics is to understand the behavior of an ensemble of strongly interacting particles. A class of quantum many-body systems such as neutron matter and cold Fermi gases share the same universal thermodynamic properties when interactions reach the maximum effective value allowed by quantum mechanics, the so-called unitary limit [1,2]. It is then possible to simulate some astrophysical phenomena inside the highly controlled environment of an atomic physics laboratory. Previous work on the thermodynamics of a two-component Fermi gas led to thermodynamic quantities averaged over the trap [3-5], making it difficult to compare with many-body theories developed for uniform gases. Here we develop a general method that provides for the first time the equation of state of a uniform gas, as well as a detailed comparison with existing theories [6,14]. The precision of our equation of state leads to new physical insights on the unitary gas. For the unpolarized gas, we prove that the low-temperature thermodynamics of the strongly interacting normal phase is well described by Fermi liquid theory and we localize the superfluid transition. For a spin-polarized system, our equation of state at zero temperature has a 2% accuracy and it extends the work of [15] on the phase diagram to a new regime of precision. We show in particular that, despite strong correlations, the normal phase behaves as a mixture of two ideal gases: a Fermi gas of bare majority atoms and a non-interacting gas of dressed quasi-particles, the fermionic polarons [10,16-18].

description: We present a catalog of 105 rich and massive ($M>3\times10^{14}M_{\sun}$) optically-selected clusters of galaxies extracted from 70 square-degrees of public archival griz imaging from the Blanco 4-m telescope acquired over 45 nights between 2005 and 2007. We use the clusters' optically-derived properties to estimate photometric redshifts, optical luminosities, richness, and masses. We complement the optical measurements with archival XMM-Newton and ROSAT X-ray data which provide additional luminosity and mass constraints on a modest fraction of the cluster sample. Two of our clusters show clear evidence for central lensing arcs; one of these has a spectacular large-diameter, nearly-complete Einstein Ring surrounding the brightest cluster galaxy. A strong motivation for this study is to identify the massive clusters that are expected to display prominent signals from the Sunyaev-Zeldovich Effect (SZE) and therefore be detected in the wide-area mm-band surveys being conducted by both the Atacama Cosmology Telescope and the South Pole Telescope. The optical sample presented here will be useful for verifying new SZE cluster candidates from these surveys, for testing the cluster selection function, and for stacking analyzes of the SZE data.

description: This work is an analysis of a colonial literature, None but ourselves; mass media vs masses in the making of Zimbabwe. The book give insights into how colonial media legacy was to be smuggled into post independent Zimbabwe. The literature also help to explain the behaviour of the government of Zimbabwe of using mass media propaganda against its own citizens. The literature give a clear picture of how state deny crisis existence. The reviewed literature also helped to explain the importance of media in shaping international relations and public opinion.

description: We extend our analysis of bound states in supersymmetric Yang–Mills theory by the consideration of baryonic operators, which are composed of three gluino fields. The corresponding states are similar to the baryons in QCD, but due to the difference between gluino and quark fields, their properties and the fermion line contractions involved in their correlation functions are different from QCD. In this work, we first explain the derivation of these operators and the contractions needed in numerical calculations of their correlators. In contrast to QCD the correlators contain a spectacle piece, which requires methods for all-to-all propagators. We provide a first estimate of the two-point function and the mass of the lightest baryonic state in supersymmetric Yang–Mills theory.

description: In order to understand the nonlinear stability of many types of time-periodic travelling waves on unbounded domains, one must overcome two main difficulties: the presence of embedded neutral eigenvalues and the time-dependence of the associated linear operator. This problem is studied in the context of time-periodic Lax shocks in systems of viscous conservation laws. Using spatial dynamics and a decomposition into separate Floquet eigenmodes, it is shown that the linear evolution for the time-dependent operator can be represented using a contour integral similar to that of the standard time-independent case. By decomposing the resulting Green's distribution, the leading order behavior associated with the embedded eigenvalues is extracted. Sharp pointwise bounds are then obtained, which are used to prove that time-periodic Lax shocks are linearly and nonlinearly stable under the necessary conditions of spectral stability and minimal multiplicity of the translational eigenvalues. The latter conditions hold, for example, for small-oscillation time-periodic waves that emerge through a supercritical Hopf bifurcation from a family of time-independent Lax shocks of possibly large amplitude.
Studies on the antigenic properties of reduced and carboxymethylated egg-white lysozyme
Creators: name: Thompson, Karen E.
Publisher: name: University of British Columbia
Year: 2011

description: This thesis involved a study of the antigenic properties of reduced and S-carboxymethylated egg-white lysozyme (CM-lysozyme). Since work on the antigenic properties of native lysozyme is currently in progress in two other laboratories, it was thought that a comparative study on CM-lysozyme might elucidate the role of primary and tertiary structure in determining antigenicity in proteins. This molecule was chosen mainly because the complete amino acid sequence, and the X-ray crystallography of the molecule have been completed. This makes it possible to correlate information on antigenic determinants with their orientation on the crystalline structure. The native molecule is relatively resistant to enzymatic digestion, but the reduced and S-carboxymethylated derivative, lacking its disulfide bridges, and consequently its rigid tertiary structure, is readily digested. The first experiments involved attempts to isolate fragments of the CM-lysozyme molecule exhibiting haptenic activity. Trypsin was used, since this is a specific endopeptidase, cleaving proteins or peptides at the carboxyl of lysine and arginine residues. Only one tryptic peptide thus isolated (T-11) exhibited haptenic activity when various fractions were tested for their ability to inhibit either precipitation or complement fixation between CM-lysozyme and its homologous antiserum. There was no cross-reactivity observed between CM-lysozyme and antiserum directed against native lysozyme. Likewise, the tryptic digest of CM-lysozyme or any of the peptides isolated from it, did not inhibit the immune reaction of native lysozyme with its homologous antiserum. Further experiments were carried out in attempts to pinpoint the region of this large 23 amino acid peptide, T-11, which was responsible for haptenic activity. From sequential degradation of the peptide from both the C- and N-terminal, using enzymatic and chemical methods, the antigenic region was narrowed to the N-terminal portion of T-11. Two synthetic peptides, prepared by the solid phase method, comprising the N-terminal decapeptide of T-11, and the decapeptide plus arginine at the N-terminal, both showed haptenic activity by inhibition of precipitation between CM-lysozyme and its homologous antiserum. The degree of inhibition with the two synthetic peptides was comparable but somewhat less efficient than the whole T-11 peptide.

description: We study the asymptotics in n for n-dimensional Toeplitz determinants whose symbols possess Fisher-Hartwig singularities on a smooth background. We prove the general non-degenerate asymptotic behavior as conjectured by Basor and Tracy. We also obtain asymptotics of Hankel determinants on a finite interval as well as determinants of Toeplitz+Hankel type. Our analysis is based on a study of the related system of orthogonal polynomials on the unit circle using the Riemann-Hilbert approach.

description: We prove that quantum many-body systems on a one-dimensional lattice locally relax to Gaussian states under non-equilibrium dynamics generated by a bosonic quadratic Hamiltonian. This is true for a large class of initial states - pure or mixed - which have to satisfy merely weak conditions concerning the decay of correlations. The considered setting is a proven instance of a situation where dynamically evolving closed quantum systems locally appear as if they had truly relaxed, to maximum entropy states for fixed second moments. This furthers the understanding of relaxation in suddenly quenched quantum many-body systems. The proof features a non-commutative central limit theorem for non-i.i.d. random variables, showing convergence to Gaussian characteristic functions, giving rise to trace-norm closeness. We briefly relate our findings to ideas of typicality and concentration of measure.

description: We examine the constraints on final state radiation from Weakly Interacting Massive Particle (WIMP) dark matter candidates annihilating into various standard model final states, as imposed by the measurement of the isotropic diffuse gamma-ray background by the Large Area Telescope aboard the Fermi Gamma-Ray Space Telescope. The expected isotropic diffuse signal from dark matter annihilation has contributions from the local Milky Way (MW) as well as from extragalactic dark matter. The signal from the MW is very insensitive to the adopted dark matter profile of the halos, and dominates the signal from extragalactic halos, which is sensitive to the low mass cut-off of the halo mass function. We adopt a conservative model for both the low halo mass survival cut-off and the substructure boost factor of the Galactic and extragalactic components, and only consider the primary final state radiation. This provides robust constraints which reach the thermal production cross-section for low mass WIMPs annihilating into hadronic modes. We also reanalyze limits from HESS observations of the Galactic Ridge region using a conservative model for the dark matter halo profile. When combined with the HESS constraint, the isotropic diffuse spectrum rules out all interpretations of the PAMELA positron excess based on dark matter annihilation into two lepton final states. Annihilation into four leptons through new intermediate states, although constrained by the data, is not excluded.

description: We provide a direct prescription for computing the mixing among gauge invariant operators in N=4 SYM. Our approach is based on the action of the superalgebra on the states of the theory and thus it can be also applied to resolve the mixing in the dual string description. As an example, we focus on the supermultiplet containing the BMN operators with two impurities. On the field theory side, we derive the leading planar quantum corrections to the naive expression of the highest weight state. Then we use the same prescription in the BMN limit of the AdS5xS5 string theory and derive the form of the 2-impurity highest weight state. The string expression matches nicely the SYM result and provides a prediction for the mixing due to higher order quantum corrections in field theory.

description: By representing the range of fair betting odds according to a pair of confidence set estimators, dual probability measures on parameter space called frequentist posteriors secure the coherence of subjective inference without any prior distribution. The closure of the set of expected losses corresponding to the dual frequentist posteriors constrains decisions without arbitrarily forcing optimization under all circumstances. This decision theory reduces to those that maximize expected utility when the pair of frequentist posteriors is induced by an exact or approximate confidence set estimator or when an automatic reduction rule is applied to the pair. In such cases, the resulting frequentist posterior is coherent in the sense that, as a probability distribution of the parameter of interest, it satisfies the axioms of the decision-theoretic and logic-theoretic systems typically cited in support of the Bayesian posterior. Unlike the p-value, the confidence level of an interval hypothesis derived from such a measure is suitable as an estimator of the indicator of hypothesis truth since it converges in sample-space probability to 1 if the hypothesis is true or to 0 otherwise under general conditions.
description: The confidence-measure theory of inference and decision is explicitly extended to vector parameters of interest. The derivation of upper and lower confidence levels from valid and nonconservative set estimators is formalized
