description: We continue the study of maximal families W of the Hilbert scheme, H(d,g)_{sc}, of smooth connected space curves whose general curve C lies on a smooth degree-s surface S containing a line. For s > 3, we extend the two ranges where W is a unique irreducible (resp. generically smooth) component of H(d,g)_{sc}. In another range, close to the boarder of the nef cone, we describe for s=4 and 5 components W that are non-reduced, leaving open the non-reducedness of only 3 (resp. 2) families for s > 5 (resp. s=5), thus making progress to recent results of Kleppe and Ottem in [28]. For s=3 we slightly extend previous results on a conjecture of non-reduced components, and in addition we show its existence in a subrange of the conjectured range.

Innovative mathematics curriculum and teacher professional learning: A case study
Creators: name: Lomas, Laurinda
Publisher: name: Australian Catholic University
Year: 2018

description: Implementation of innovative curriculum is posited as an immersion strategy with the potential to deepen the mathematical knowledge of in-service teachers. The impact of beliefs on teacher practice, however, can be a substantial constraint in this change process. The purpose of this research was to explore the impact of teaching an innovative mathematics unit on teachers’ knowledge and beliefs about mathematics and mathematics teaching and learning. Using a case study methodology within a constructivist epistemology, two Year 5/6 teachers were studied as they taught a rational number unit of work originally developed in the Netherlands, underpinned by Realistic Mathematics Education (see, e.g., Streefland, 1991). The interconnected model of teacher growth (Clarke & Hollingsworth, 2002) provided the theoretical model of change in this study, and the mathematical knowledge for teaching model (Ball, Thames, & Phelps, 2008) was used to analyse knowledge growth. The initial relationship between the case study teachers and innovative curriculum was pivotal in determining curriculum fidelity and the potential for meaningful change. Both teachers were very experienced and had volunteered for the immersion experience, but issues of trust and teacher authority constrained long-term change. Neither of the teachers in this trial took the full opportunity to learn afforded by the innovative curriculum because they did not seem prepared to reflect seriously on their established beliefs about teaching in general. One of the teachers was open to learning new ways to teach fractions and was pleased at the surprising responses of students he had previously considered lower achieving. This resulted in subject matter and pedagogical content knowledge growth, as he considered the problem-solving strategies promoted by the unit better than those he had used in his career. The second case study teacher’s negative attitude towards the innovative curriculum based on previous experiences overseas resulted in constant concern about extending higher achieving students. She found managing the dissonance of her goals for teaching with those of the innovative curriculum extremely difficult to reconcile, resulting in a reduced number of lessons taught, little long-term growth in knowledge, and no apparent change in beliefs. This research suggests that innovative curricula like those based on Realistic Mathematics Education have the potential to challenge the conceptual schema of teachers, but only if they are open to such experiences. Considering the resilient influence of beliefs on teacher practice observed in this research and its status in the change environment, strategies that both challenge and support teachers are needed if serious and sustained growth is to be realised.

description: Many schemes to realize quantum state transfer in spin chains are not robust to random fluctuations in the spin-spin coupling strength. In efforts to achieve robust quantum state transfer, an adiabatic quantum population transfer scheme is proposed in this study. The proposed scheme makes use of a slowly moving external parabolic potential and is qualitatively explained in terms of the adiabatic following of a quantum state with a moving separatrix structure in the classical phase space of a pendulum analogy. Detailed aspects of our adiabatic population transfer scheme, including its robustness, is studied computationally. Applications of our adiabatic scheme in quantum information transfer are also discussed, with emphasis placed on the usage of a dual spin chain to encode quantum phases. The results should also be useful for the control of electron tunneling in an array of quantum dots.

description: We show that if there are only two Higgs doublets in the supersymmetric standard model, large $\tanβ$ requires a fine tuning in the parameters of the Lagrangian of order ($1/\tanβ$), which cannot be explained by any approximate symmetry. With an extended Higgs sector, large $\tanβ$ can be natural. We give an explicit example with four doublets in which it is possible to achieve large $\tanβ$ as a result of an approximate symmetry, without any light superpartners. The approximate symmetry can be extended to explain all the hierarchies in the quark mass matrix.

description: We fabricated a non-local spin valve device with Co-MgO injector/detector tunnel contacts on a graphene spin channel. In this device, the spin polarization of the injector contact can be tuned by both the injector current bias and the gate voltage. The spin polarization can be turned off and even inverted. This behavior enables a spin transistor where the signal is switched off by turning off the spin injection using the field-effect. We propose a model based on a gate-dependent shift of the minimum in the graphene density of states with respect to the tunneling density of states of cobalt, which can explain the observed bias and gate dependence.

description: Higher education institutions have emphasized retention as one of the measurable outcomes linked with institutional performance, state and federal funding appropriations, and publicized rankings (Hagedorn, 2012). Therefore, higher education institutions intentionally have become more focused on providing a robust first-year college experience, including high-impact practices intended to help with adjustment, transition, and retention of students during their first year. One high-impact practice is a formal mentoring program focused on relationship building, positive peer support, and social guidance (Kuh, Cruce, Shoup, Kinzie, & Gonyea, 2008; Kuh, Kinzie, Buckley, Bridges & Hayek, 2006). More specifically, peer mentoring is an important component of a student’s first year and undergraduate experience (Crisp & Cruz, 2009; Crisp et al., 2017; Gershenfeld, 2014; Jacobi, 1991; Miller, 2004). Mentorability is a term that conceptualizes mentees’ ability to engage in a mutually beneficial and developmental relationship (Reddick, 2014). It focuses on mentees understanding of their role and responsibilities engaging in the relationship. This study employed a phenomenological approach in examining how 17 mentees described their lived experiences of and how they perceived their ability to commit, contribute, and engage in a peer mentoring partnership in a formal mentoring program at an Hispanic Serving Institution. The key findings of the study demonstrated: (1) mentorability as a process: from unclear expectations to viewing a mentor as a lifeline for success; (2) mentees as information seekers and mentors as influential contributors; and (3) communication and open-mindedness as key mentee contributions, trust as a gatekeeper for relationship formation, and mentorability as multi-level of exchange including understanding a mentee’s role extends beyond the reciprocity with the mentor to other peers. Drawing from three social science theories, this study introduces a mentorability conceptual model for practice derived from findings from the study (Astin, 1993; Lin, 2001; Cropanzano et al., 2017). Additional findings, and implications for future research, practice, and theory are discussed.

description: We propose a model in which firms involved in trading securities overinvest in financial expertise. Intermediaries or traders in the model meet and bargain over a financial asset. As in the bargaining model in Dang (2008), counterparties endogenously decide whether to acquire information, which improves their bargaining position, even though the information has the potential to create adverse selection. We add to this setting the concept of financial expertise" as resources invested to lower the cost of later acquiring information about the value of the assets traded. These investments are made before the parties know about their role in the bargaining game, as proposer or responder, buyer or seller. A prisoner's dilemma arises because investments to lower information acquisition costs improve bargaining outcomes given the other party's information costs, even though the information has no social benefit. These investments lead to breakdowns in trade, or liquidity crises, in response to random but infrequent increases in asset volatility. Persistence in the volatility process can produce contractions and expansions resembling employment cycles for financial experts.

description: The beam hosing instability is analyzed theoretically for a witness beam in the quasi-linear regime of plasma accelerators. In this regime, the hosing instability saturates, even for a monoenergetic bunch, at a level much less than standard scalings predict. Analytic expressions are derived for the saturation distance and amplitude and are in agreement with numerical results. Saturation is due to the natural head-to-tail variations in the focusing force, including the self-consistent transverse beam loading.

description: In finite mixtures of location-scale distributions, if there is no constraint or penalty on the parameters, then the maximum likelihood estimator does not exist because the likelihood is unbounded. To avoid this problem, we consider a penalized likelihood, where the penalty is a function of the minimum of the ratios of the scale parameters and the sample size. It is shown that the penalized maximum likelihood estimator is strongly consistent. We also analyze the consistency of a penalized maximum likelihood estimator where the penalty is imposed on the scale parameters themselves.

description: In technical problems where decisions must simultaneously satisfy several conflicting objectives, methods are based on benefit-cost analysis or multicriteria decision analysis helpful to identify the “optimal” decision. Usually big technical decisions are made by politics and influence the environment, but specialists, constructors and the society must have the ability to overview and inspect these decisions. In the theory of economics, the level of financial growth is used as an indicator for assessing social prosperity. However, the growth rate might be accompanied by unfavorable effects on the social community’s prosperity. Such negative effects are for instance the danger against public health lying in the environmental pollution, the dangerous shrinking of biodiversity and the exhaustion of natural resources. Within this context, the concept of the environmental preservation has been developed, i.e. the long-term preservation of the ecosystem’s viability, as well as the concept of sustainability, that is covering present needs but not to the detriment of future needs. It has been observed that society develops a discerning ability on technological applications (hence an ecological predisposition) when it reaches such a stage of maturity where it comes up against the pollutants it produces itself. This phenomenon, as it is described in Environmental Psychology, is “as if you’re waiting for a building to catch fire in order to study the new safety rules regarding buildings’ fires’’. It continues then, “it is rather immoral to wait for a building to catch fire so that you’re given the criteria on how to study the new safety rules regarding buildings’ fires’’. (Cander, 1988). A building, is a creation of humans which affects both the environment and humans themselves. A building might negatively affect humans and the environment during its construction and operation stages or can emerge as spoilage after its use. For this reason, different criteria arise to define the building’s ecological behavior so that the positive effect is maximized and the possible unfavorable effects to humans and the natural ecosystem are minimized. Extensive analysis of the problem from several viewpoints and a presentation of the reasoning are necessary to achieve an informed decision based on understanding and knowledge. In order to optimize a technical decision for society, engineers, experts and politics, architecture of a web platform based in "common" knowledge, optimizes the decision making analysis by evaluating building materials based on ecological criteria.

How many radio-loud quasars can be detected by the Gamma-Ray Large Area Space Telescope?

description: In the unification scheme, radio quasars and FR II radio galaxies come from the same parent population, but viewed at different angles. Based on the Comptonization models for the gamma-ray emission from active galactic nuclei (AGNs), we estimate the number of radio quasars and FR II radio galaxies to be detected by the Gamma-Ray Large Area Space Telescope (GLAST) using the luminosity function (LF) of their parent population derived from the flat-spectrum radio quasar (FSRQ) LF. We find that ~1200 radio quasars will be detected by GLAST, if the soft seed photons for Comptonization come from the regions outside the jets. We also consider the synchrotron self-Comptonization (SSC) model, and find it unlikely to be responsible for gamma-ray emission from radio quasars. We find that no FR II radio galaxies will be detected by GLAST. Our results show that most radio AGNs to be detected by GLAST will be FSRQs (~99 % for the external Comptonization model, EC model), while the remainder (~1 %) will be steep-spectrum radio quasars (SSRQs). This implies that FSRQs will still be good candidates for identifying gamma-ray AGNs even for the GLAST sources. The contribution of all radio quasars and FR II radio galaxies to the extragalactic gamma-ray background (EGRB) is calculated, which accounts for ~30 % of the EGRB.

description: Financial collapse in the winter of 1933 culminating in the "bank holiday" of early March, was a climactic event. It ended the downswing phase of the great depression. It produced widespread losses to depositors and owners of bank capital that led soon after to the establishment of the Securities and Exchange Commission, separation of commercial and investment banking, Federal deposit insurance, and other landmark financial legislation. It put an end to the gold standard in the United States, followed, in a few years, by the remaining adherents.

De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions.

 range. This dissertation reports on the development of two novel methods
 for the

 application of the well-known Swanepoel method in the case where normal
 incidence reflectance spectra are unavailable. By utilising linear
 regression of oblique angle reflectance spectra to determine normal
 incidence values, the required input data for the standard Swanepoel
 method can be calculated without direct measurement of normal incidence
 reflectance. Dispersive refractive indices calculated from this first
 method are shown to be in good agreement with literature data and are
 applied to the modelling of a DBR stopband, where they show significant
 improvement in agreement between modelled and measured reflectance when
 compared to experimental literature. The second method determines
 non-dispersive infrared refractive indices by a second-order Taylor
 expansion of Swanepoel’s equations and is shown to be capable of
 predicting a reasonable trend in the refractive index of dilute

description: Many combinatorial problems, such as bin packing, set covering, and combinatorial design, can be conveniently expressed using set variables and constraints over these variables [3]. In constraint programming such problems can be modeled directly in their natural form by means of set variables. This offers a great potential in exploiting the structure captured by set variables during the solution process, for example to break problem symmetry or to improve domain filtering. We present an efficient filtering algorithm, establishing bounds consistency, for the atmost1 constraint on pairs of set variables with fixed cardinality. Computational results on social golfer benchmark problems demonstrate that with this additional filtering, these problems can be solved up to 50 times faster.

We find that these amplitudes are zero except for the lowest possible $n_1$ and $n_2$, and that the cancellation of the corresponding Feynman graphs occurs due to a special symmetry of the classical mechanical counterpart of this theory. This feature is rather general and is inherent in various other scalar field theories.

description: Maintaining energy balance and economical operation is significant for multi-energy systems such as the energy hub. However, it is usually challenged by the frequently changing and unpredictable uncertainties at different timescales. Under this scope, this paper investigates the coordinated energy management problem for day-ahead and intra-day conditions considering uncertainties of source-load and market prices concurrently. Note that the precise knowledge of distributions about uncertainties may be unaccessible before the decision-making in day-ahead phase. A two-stage chance-constrained model based on distributionally robust approach with ambiguous moment information is proposed to immunize scheduling strategies against the worst-case probability distributions. The first stage is dedicated to obtaining more energy arbitrage and operation flexibility by optimizing bidding strategies in day-ahead power, natural gas and carbon markets. The second stage focuses on the optimization of worst-case expected operation cost. It provides a robust energy equipment and load scheduling strategy for the reference of subsequent intra-day arrangements. With respect to different variations of electrical and thermal components, an intra-day two-timescale coordination is implemented step by step. The energy scheduling is re-dispatched circularly to minimize the operation and penalty costs. The possible energy imbalance is also compensated by this way. As the energy management program is nonlinear, chance-constrained and multi-stage, linearization and dual transformation techniques are designed to enhance tractability of programs. Experimental results show that the developed multi-level framework results in a carbon emission decrease of 37%, and reduces energy cost averagely 3% compared with corresponding contrasting cases. The obtained strategy validates a good tradeoff between robustness and optimality.

description: Ralph Bryant tells us both at the start and at the end of his paper that the issue he discusses is of minor importance. His announced aim is pedagogical; he seeks to eliminate one source of confusion or misperception about monetary control. Some misled economists and 4 4most noneconomists . . . seem to believe that the Federal Reserve can straightforwardly cause the money stock to follow a target path closely— month by month—provided only that the Federal Reserve conscientiously tries to do so." This is not so, Bryant tells us. His paper attempts to explain why. Regrettably, he gives as much attention to transitory fluctuations in float or excess reserves as to serially correlated, persistent disturbances in borrowing or demand deposits. He neglects the serious issues that divide the Federal Reserve and its critics.

description: [transcription] [Brouillon de réponse de Séguier]

M.R.P.

L'état où je [me] trouve depuis environ un mois, tourmenté des douleurs de rhumatisme, ne me permet point de m'occuper des matières qui exigent quelque contention d'esprit. c'est ce qui m'empêche de répondre au mémoire que vous m'avez envoyé de la part de vos compatriotes. Je suis fort sensible à l'honneur qu'ils me font et me fâche de ne pouvoir satisfaire leurs dessins. Je dirai seulement en général que les médailles et les inscriptions nous apprennent que Néron ne fut proclamé que trois fois Imperator. Que lorsqu'il s'agit d'inscriptions de pierres miliaires, comme elles sont rapportées dans l'étendue de la voie, celle qui est la mieux lisible est la plus conforme à l'histoire doit prévaloir sur les autres. Or, dans le cas présent, le miliaire de Luc sur lequel on lit clairement Trib. Pot. IIII Imp. Iter, doit prévaloir sur celui qui est chez Monsieur de Valbelle, et je crois que le savant Père Papon a eu raison de dire qu'il faut lire Imp. Iterum conformément à celui du Luc. Quand même il serait bien constaté que celui chez Monsieur Valbelle porte Imp. IIII. Il faudrait regarder ce nombre comme une faute de l'ouvrier. On m'a ci-devant envoyé cette transcription et on y a marqué avec beaucoup d'exactitude toutes les petites omissions et défauts qui s'y trouvent et je ne suis pas surpris que ce IIII doive être réfuté pourtant.

A l'égard de la seconde, il est clair que l'inscription appartient à Caligula qui constamment sur sa médaille se nomme Caius Caesar Germanicus et il faut lire sur l'inscription Pro salute Caii Caesarius Germanici filis Germanici Augusti pagus. Matavoncus et ne point séparer les trois dernières lettres pour en faire des sigles.

description: We study the modulations of the superconducting order parameter in the vicinity of edges, magnetic and non-magnetic impurities by self-consistently solving the gap equations of a system with competing interactions in the Cooper channel. It is shown that the presence or absence of Friedel-like oscillations of the superconducting order parameter crucially depends on its symmetry and can, hence, be used to obtain information about the symmetry properties of the condensate. Furthermore, the appearance of competing order parameters at inhomogeneities is discussed. We show that this can lead to the presence of a topologically trivial region close to the boundary of a system that is topologically nontrivial in its bulk. The resulting shift in position of the Majorana bound states is demonstrated to significantly affect its signatures in Josephson-junction experiments. We discuss Josephson scanning tunneling microscopy as a probe to resolve the Friedel-like oscillations as well as the spatial texture of competing s-wave superconductivity and Majorana bound states in the vicinity of the edge of the system.

description: Two fallacies have received much attention this summer. One is that the U.S., or perhaps the world, is in imminent danger of deflation — defined as persistently falling prices. The other is that the decline in the prices of gold and a few selected commodities presage a decline in all prices — that the decline in gold and commodity prices is a leading indicator of future changes in all other prices and wages.

description: Central engine of gamma-ray bursts (GRBs) may be intermittent and launch several episodes of ejecta separated by a long quiescent interval. In this scenario, an external shock is formed due to the propagation of the first launched ejecta into the circum-burst medium and the later launched ejecta may interact with the external shock at later period. Owing to the internal dissipation, the later launched ejecta may be observed at a later time ($t_{\rm{jet}}$). In this paper, we study the relation of $t_{\rm{b}}$ and $t_{\rm{jet}}$, where $t_{\rm{b}}$ is the collision time of the later launched ejecta with the formed external shock. It is found that the relation of $t_{\rm{b}}$ and $t_{\rm{jet}}$ depends on the bulk Lorentz factor ($Γ_{\rm{jet}}$) of the later launched ejecta and the density ($ρ$) of the circum-burst medium. If the value of $Γ_{\rm{jet}}$ or $ρ$ is low, the $t_{\rm{b}}$ would be significantly larger than $t_{\rm{jet}}$. However, the $t_{\rm{b}}\sim t_{\rm{jet}}$ can be found if the value of $Γ_{\rm{jet}}$ or $ρ$ is significantly large. Our results can explain the large lag of the optical emission relative to the $γ$-ray/X-ray emission in GRBs, e.g., GRB~111209A. For GRBs with a precursor, our results suggest that the energy injection into the external shock and thus more than one external-reverse shock may appear in the main prompt emission phase. According to our model, we estimate the Lorentz factor of the second launched ejecta in GRB~160625B.

The Black Hole-Bulge Relationship in Luminous Broad-Line Active Galactic Nuclei and Host Galaxies

description: We have measured the stellar velocity dispersions (σ_*) and estimated the central black hole (BH) masses for over 900 broad-line active galactic nuclei (AGNs) observed with the Sloan Digital Sky Survey. The sample includes objects which have redshifts up to z=0.452, high quality spectra, and host galaxy spectra dominated by an early-type (bulge) component. The AGN and host galaxy spectral components were decomposed using an eigenspectrum technique. The BH masses (M_BH) were estimated from the AGN broad-line widths, and the velocity dispersions were measured from the stellar absorption spectra of the host galaxies. The range of black hole masses covered by the sample is approximately 10^6 < M_BH < 10^9 M_Sun. The host galaxy luminosity-velocity dispersion relationship follows the well-known Faber-Jackson relation for early-type galaxies, with a power-law slope 4.33+-0.21. The estimated BH masses are correlated with both the host luminosities (L_{H}) and the stellar velocity dispersions (σ_*), similar to the relationships found for low-redshift, bulge-dominated galaxies. The intrinsic scatter in the correlations are large (~0.4 dex), but the very large sample size allows tight constraints to be placed on the mean relationships: M_BH ~ L_H^{0.73+-0.05} and M_BH ~ σ_*^{3.34+-0.24}. The amplitude of the M_BH-σ_* relation depends on the estimated Eddington ratio, such that objects with larger Eddington ratios have smaller black hole masses than expected at a given velocity dispersion.

description: We present in this talk recent investigations on the nucleon-like resonance N*(1675) newly found in eta photoproduction by the GRAAL, Tohoku LNS-gamma and CB-ELSA collaborations. We focus on the production mechanism of the N*(1675), examining its spin and parity theoretically within the framework of the effective Lagrangian method. We expliucitly consider D_{13}(1520), S_{11}(1535), S_{11}(1650), D_{15}(1675), P_{11}(1710), P_{13}(1720) as well as possible background contributions. We calculate the differential cross sections and beam asymmetries for the neutron and proton targets. It turns out that there is manifest isospin asymmetry in eta photoproduction, which can be explained by the asymmetry in the transition magnetic moments: mu_{gamma p p*} =

description: The average effective mass of charge carriers produced by an intense ultrashort laser pulse in a transparent solid increases significantly as the excitation mechanism changes from multiphoton transitions to interband tunneling. We theoretically investigate this phenomenon for several dielectrics and semiconductors. For diamond as a representative dielectric, we present a detailed analysis of the laser-induced change of optical properties. When the concentration of free carriers is high, we find that the average effective mass controls not only the intraband charge-carrier transport but also the interband contributions to the optical response. We observe that the excitation-induced birefringence is particularly large for parameters where the plasma response compensates for the linear response of an unperturbed solid.

description: We describe a specialized dynamic programming algorithm for factory crane scheduling. An innovative data structure controls the memory requirements of the state space and enables solution of problems of realistic size. The algorithm finds optimal spacetime trajectories for two factory cranes or hoists that move along a single overhead track. Each crane is assigned a sequence of pickups and deliveries at specified locations that must be performed within given time windows. The cranes must not interfere with each other, although one may yield to the other. The state space representation permits a wide variety of constraints and objective functions. It is stored in a compressed data structure that uses a cartesian product of intervals of states and an array of two-dimensional circular queues. We also show that only certain types of trajectories need be considered. The algorithm found optimal solutions in less than a minute for medium-sized instances of the problem (160 tasks, spanning four hours). It can also be used to create benchmarks for tuning heuristic algorithms that solve larger instances.

description: This research examines the effect of individual, role, and organizational factors on perceptions of the organizational pay system. All three factors contribute to the variations in the perceived instrumental relationship between pay and performance. Role and organizational factor's exhibited the strongest relationship. The associations between the antecedent variables and the perceived instrumentalities are affected also by the degree of formalization in the company's merit system and in whether the population was managerial or blue collar. A general framework concerning how perceptions about reward systems are acquired is discussed.
Theoretical analysis for the apparent discrepancy between pbarp and pp data in charged particle forward-backward multiplicity correlations

description: The strength of charged particle forward-backward multiplicity correlation in pbar+p and p+p collisions at s^1/2 = 200 GeV is studied by PYTHIA 6.4 and compared to the UA5 and STAR data correspondingly. It is turned out that a factor of 3-4 apparent discrepancy between UA5 and STAR data can be attributed to the differences in detector acceptances and observing bin interval in both experiments. A mixed event method is introduced and used to calculate the statistical correlation strength and the dynamical correlation strengths stemming from the charge conservation, four- momentum conservation, and decay, respectively. It seems that the statistical correlation is much larger than dynamical one and the charge conservation, four-momentum conservation and decay may account for most part of the dynamical correlation. In addition, we have also calculated the correlation strength by fitting the charged particle multiplicity distribution from PYTHIA to the Negative Binomial Distribution and found that the result agrees well with the correlation strength calculated by mixed events.
