description: This is part two in a series of papers in which we investigate an approach based on Lagrangian perturbation theory (LPT) to study the non-linear evolution of the large-scale structure distribution in the universe. Firstly, we compute the matter bispectrum in real space using LPT up one-loop order, for both Gaussian and non-Gaussian initial conditions. In the initial position limit, we find that the one-loop bispectrum computed in this manner is identical to its counterpart obtained from standard Eulerian perturbation theory (SPT). Furthermore, the LPT formalism allows for a simple reorganisation of the perturbative series corresponding to the resummation of an infinite series of perturbations in SPT. Applying this method, we find a resummed one-loop bispectrum that compares favourably with results from N-body simulations. We generalise the resummation method also to the computation of the redshift-space bispectrum up to one loop.

title:  Vital Tooth Whitening Effects on Oral Health-Related Quality of Life in Older Adults
Creators: name: Poindexter, Ann Michelle
Publisher: name: Old Dominion University Libraries
Year: 2007

description: This study determined if vital tooth whitening affects oral health-related quality of life (OHRQOL) in adults ≥50-years old, and if tooth whitening promotes individuals to seek regular professional dental care and participation in social activities. Using a two-group, single blind, randomized, pre-test-post-test design, 62 participants were enrolled. The experimental group used a whitening product twice daily for three weeks, while the control group used no whitening products. Tooth color satisfaction was assessed using the Tooth Color Satisfaction Scale and was correlated with overall oral health-related quality of life. The Oral Health Impact Profile (OHIP), used as the pre-test and post-test measures oral health-related quality of life on seven subscales: functional factors, psychological disabilities, psychological discomforts, physical disabilities, social disabilities, handicaps, and physical pain. The Additional Questions Survey measured the participants' number of social activities and dental care encounters at baseline, three weeks, and three months. Data from 53 participants who completed the study were analyzed using paired t-tests and ANOV A at p≤.05. Whitening group pre-test to post-test scores changed significantly on the handicap subscale, suggesting that persons who experienced tooth whitening were more willing to work due to a perceived increase in health associated with tooth whitening. A statistically significant difference was observed for the physical pain subscale with the whitening group reporting more pain.

Pre-test to post-test physical pain subscale means increased in the whitening group suggesting a lower oral health-related quality of life for participants. Repeated measures ANOVA and Tukey's post-hoc tests revealed that the whitening group reported significantly less social activities at the three-month post-test. No statistically significant differences were observed in the overall OHIP score or for functional factors, psychological disabilities, psychological discomforts, physical disabilities, and social disabilities subscales. Regression analysis relating tooth color satisfaction with overall oral health-related quality of life revealed a significant correlation between tooth color satisfaction and overall OHIP for the whitening group. Participants who whitened their teeth reported an increase in tooth color satisfaction; tooth whitening did not improve their overall oral-health related quality of life.

description: Sprachliche Fähigkeiten unterscheiden sich bei Kindern im Alter von vier bis fünf Jahren mitunter deutlich nach der Bildung der Eltern. Die meisten bisherigen Studien – und damit auch viele bildungspolitische Maßnahmen – orientierten sich mit Blick auf die Sprachkompetenzwerte am Durchschnitt innerhalb der verschiedenen Bildungsgruppen. Dieser Bericht zeigt, dass dies zu kurz greift und mögliche Ungleichheitsmuster im Verborgenen bleiben. Als einer von wenigen untersucht er die Verteilung der Sprachkompetenzen detaillierter. Dabei zeigt sich auf Basis von Daten des Nationalen Bildungspanels (NEPS), dass die Unterschiede nach der Bildung der Eltern im unteren Sprachleistungsbereich deutlich größer sind. Kinder mit niedrigerem Bildungshintergrund sind also stärker benachteiligt und müssen sehr viel mehr aufholen als bisher gedacht. Die Ergebnisse sind insbesondere vor dem Hintergrund relevant, dass jährlich mehrere Millionen Euro in Förderprogramme zum Spracherwerb fließen. Um Unterschiede nach der Bildung der Eltern zu reduzieren, sollten Programme so ausgestaltet sein, dass leistungsschwächere Kinder aus bildungsferneren Familien deutlich gezielter unterstützt werden.

description: Die „Rente mit 67“ ist ein zentraler rentenpolitischer Baustein zur Bewältigung der Folgen des demografischen Wandels. Sie sieht vor, dass das Regelrenteneintrittsalter zwischen 2012 und 2031 von 65 auf 67 Jahre steigt. Allerdings geht diese Strategie nur dann auf, wenn es den Menschen gelingt, ihren Erwerbsaustritt auch wirklich in ein höheres Alter zu verschieben. Unter den aktuell sehr günstigen Arbeitsmarktbedingungen gelingt dies deutlich mehr Menschen als noch vor zehn Jahren. Allerdings bestehen große Unsicherheiten, ob sich dieser Trend so fortsetzen kann. Anhand des am DIW Berlin entwickelten Dynamischen Mikrosimulationsmodells (DySiMo) werden die Wirkungen der Anhebung der Altersgrenzen unter zwei verschiedenen Arbeitsmarktszenarien simuliert. Das durchschnittliche Zugangsalter in die Altersrente wird in den kommenden Jahren nach den Schätzungen um weitere 1,2 bis 1,5 Jahre steigen. Falls die Beschäftigungsquoten der 60- bis 67-Jährigen auf dem heutigen Niveau verharren, werden aber weiterhin rund 40 Prozent (bei optimistischer Prognose nur 20 Prozent) aller Rentenzugänge nicht aus einem Beschäftigungsverhältnis erfolgen. Deshalb müssen gerade bei einer weiteren Anhebung der Altersgrenzen Lösungen für unterschiedliche Risikogruppen gefunden und die Möglichkeiten für einen gleitenden Ausstieg aus dem Erwerbsleben verbessert werden.

Institutional change in regional organizations : the emergence and evolution of ASEAN norms
Creators: name: Poole, Avery Dorothy Howard
Publisher: name: University of British Columbia
Year: 2013

description: In November 2007, the member states of the Association of Southeast Asian Nations (ASEAN) signed their first Charter, and hailed it as a ‘milestone’ for regional cooperation. The Charter was designed to provide the ‘legal and institutional framework’ for ASEAN, and to give it a ‘legal personality’. It refers to ‘strengthening’ the principle of democracy and to ‘promoting and protecting’ human rights. It also states that ASEAN ‘shall establish an ASEAN human rights body’. The Charter raises an empirical puzzle given the ASEAN norms of sovereignty and ‘non-interference in the internal affairs of one another’, which are reiterated in ASEAN declarations and agreements (including the Charter). Moreover, the significant political, ethnic and cultural diversity among member states traditionally underpins the understanding that regime type and human rights are ‘off the table’ in (official) ASEAN dialogue. Thus, why did ASEAN member states adopt text in the Charter referring to democracy and human rights? Further, why was the debate about the references to human rights far more contentious than that about the references to democracy? This dissertation traces the negotiations leading to the ASEAN Charter, and explores the processes through which member states accepted the references to democracy and human rights, and agreed to establish an ASEAN human rights body. I argue that perceptions of legitimacy influence states’ positions on regional ‘normative statements’. The emergence and evolution of regional norms are shaped by political elites’ perceptions of how members of a regional organization view the legitimacy of the organization and its norms (which I call ‘internal regional legitimacy’). These are in turn shaped by elites’ perceptions of how their societies regard the legitimacy of their national governments (‘domestic political legitimacy’). Regional norms are also shaped by elites’ perceptions of how those outside the region view the legitimacy of the regional organization and its norms (‘external regional legitimacy’). The dissertation’s exploration of various actors’ perceptions of legitimacy in the adoption of the Charter helps to explain the diverse understandings of norms by member states. Moreover, it contributes to theoretical understandings of the emergence and evolution of norms in an environment of ‘normative contestation’.

description: String diagrams are a powerful tool for reasoning about physical processes, logic circuits, tensor networks, and many other compositional structures. Dixon, Duncan and Kissinger introduced string graphs, which are a combinatoric representations of string diagrams, amenable to automated reasoning about diagrammatic theories via graph rewrite systems. In this extended abstract, we show how the power of such rewrite systems can be greatly extended by introducing pattern graphs, which provide a means of expressing infinite families of rewrite rules where certain marked subgraphs, called !-boxes ("bang boxes"), on both sides of a rule can be copied any number of times or removed. After reviewing the string graph formalism, we show how string graphs can be extended to pattern graphs and how pattern graphs and pattern rewrite rules can be instantiated to concrete string graphs and rewrite rules. We then provide examples demonstrating the expressive power of pattern graphs and how they can be applied to study interacting algebraic structures that are central to categorical quantum mechanics.

description: Repräsentative Befragungsergebnisse zeigen in Deutschland seit 2016/17 eine stabile Zustimmungsrate zur Einführung eines bedingungslosen Grundeinkommens, zwischen 45 und 52 Prozent; im europäischen Vergleich sind diese Zustimmungsraten eher gering. Gerade junge, höher gebildete und von Armut bedrohte Menschen unterstützen in Deutschland die Idee eines bedingungslosen Grundeinkommens. Aber nicht nur die eigene Position, sondern auch subjektive Gerechtigkeitseinstellungen stehen im Zusammenhang mit der Einstellung zum bedingungslosen Grundeinkommen. Leistungsgerechtigkeit und bedingungsloses Grundeinkommen stehen scheinbar im Widerspruch. Werden hingegen Defizite bei der Deckung des Bedarfs im unteren Einkommensbereich der Gesellschaft festgestellt, geht dies eher mit einer Befürwortung des bedingungslosen Grundeinkommens einher. Die Analysen zeigen somit, dass die Einstellung zum bedingungslosen Grundeinkommen bestimmten Mustern und sozialen Regelmäßigkeiten folgt und im Zeitraum 2016 bis 2018 relativ stabil ist. Solange die gesellschaftlichen Kosten und Nutzen der Einführung eines solchen Grundeinkommens weitestgehend unklar sind, ist der vergleichsweise hohe Anteil an Befürworterinnen und Befürwortern mit Vorsicht zu interpretieren und nicht gleichzusetzen mit einer tatsächlichen Reformbereitschaft in der Bevölkerung.

Search for tb resonances in proton-proton collisions at sqrt(s) = 7 TeV with the ATLAS detector
Creators: name: ATLAS Collaboration
Publisher: name: arXiv
Year: 2012
Subjects: subject: High Energy Physics - Experiment (hep-ex)

description: This Letter presents a search for tb resonances in 1.04/fb of LHC proton-proton collision data collected by the ATLAS detector at a center-of-mass energy of 7 TeV. Events with a lepton, missing transverse momentum, and two jets are selected and the invariant mass of the corresponding final state is reconstructed. The search exploits the shape of the tb invariant mass distribution compared to the expected Standard Model backgrounds. The model of a right-handed W'_R with Standard Model-like couplings is chosen as the benchmark model for this search. No statistically significant excess of events is observed in data, and upper limits on the cross section times the branching ratio of W'_R resonances at 95% CL lie in the range 6.1-1.0 pb for W'_R masses ranging from 0.5 to 2.0 TeV. These limits are translated into a lower bound on the allowed right-handed W'_R mass, giving m_{W'_R} > 1.13 TeV at 95% CL.

description: Die Zahl der abhängig Beschäftigten in Deutschland ist seit der Finanzkrise um mehr als vier Millionen gestiegen. Ein Teil dieses Beschäftigungsaufbaus fand im Niedriglohnsektor statt. Analysen auf Basis von Daten des Sozio-oekonomischen Panels, die erstmalig ausreichend Details über Nebentätigkeiten liefern, zeigen, dass es im Jahr 2017 über neun Millionen Beschäftigungsverhältnisse mit einem Lohn unterhalb der Niedriglohnschwelle gab, was einem Anteil von rund einem Viertel aller Beschäftigungsverhältnisse entspricht. Frauen, junge Erwachsene und Ostdeutsche erhalten besonders häufig Niedriglöhne. Da der allgemeine Mindestlohn unter der Niedriglohnschwelle lag, hat seine Einführung im Jahr 2015 den Anteil der Niedriglohnbeschäftigten nicht gesenkt, obwohl die Löhne im unteren Segment deutlich gestiegen sind. Die Mobilität in der Lohnverteilung hat sich seit Mitte der 1990er Jahre kaum verändert: Etwa zwei Drittel der Niedriglohnbeschäftigten verharren mittelfristig in ihrer Lohngruppe. Um den Niedriglohnsektor einzudämmen, sind Reformen bei den Minijobs, sowie Anstrengungen bei der Qualifikation und eine offensivere Lohnpolitik gefragt.

These solutions are Kundt metrics, constructed from a one-parameter family of three dimensional Gauduchon-Tod base spaces. We give examples, including the near horizon geometries previously found in arxiv:hep-th/10122120. In addition, two special cases are considered in detail. In the first, we consider solutions for which the Gauduchon-Tod base space is the Berger sphere. In the second case we take the null 1-form Killing spinor bilinear to be recurrent, so that the holonomy of the Levi-Civita connection is contained in Sim(3).

description: We develop a bottom-up approach to studying SUSY with light stops and sbottoms, but with other squarks and sleptons heavy and beyond reach of the LHC. We discuss the range of squark, gaugino and Higgsino masses for which the electroweak scale is radiatively stable over the "little hierarchy" below ~ 10 TeV. We review and expand on indirect constraints on this scenario, in particular from flavor and CP tests. We emphasize that in this context, R-parity violation is very well motivated. The phenomenological differences between Majorana and Dirac gauginos are also discussed. Finally, we focus on the light subsystem of stops, sbottom and neutralino with R-parity, in order to probe the current collider bounds. We find that 1/fb LHC bounds are mild and large parts of the motivated parameter space remain open, while the 10/fb data can be much more decisive.

description: We study in this paper a series of Gutzwiller Projected wavefunctions for S=1 spin chains obtained from a fermionic mean-field theory for general S>1/2 spin systems [Phys. Rev. B 81, 224417] applied to the bilinear-biquadratic (J-K) model. The free-fermion mean field states before the projection are 1D paring states. By comparing the energies and correlation functions of the projected pairing states with those obtained from known results, we show that the optimized Gutzwiller projected wavefunctions are very good trial ground state wavefunctions for the antiferromagnetic bilinear-biquadratic model in the regime K0). We find that different topological phases of the free-fermion paring states correspond to different spin phases: the weak pairing (topologically non-trivial) state gives rise to the Haldane phase, whereas the strong pairing (topologically trivial) state gives rise to the dimer phase. In particular the mapping between the Haldane phase and Gutwziller wavefunction is exact at the AKLT point K=1/3. The transition point between the two phases determined by the optimized Gutzwiller Projected wavefunction is in good agreement with the known result. The effect of Z2 gauge fluctuations above the mean field theory is analyzed.

description: Under some well-defined conditions, the mathematical formalism of quantum mechanics enables physicists, chemists and others to calculate and predict the outcome of a vast number of experiments. In fact, especially the Schr?dinger equation which involves an imaginary quantity describes how a quantum state of a physical system changes with time and is one of the main pillars of modern quantum mechanics. The wave function itself is a determining part of the Schrödinger equation, but the physical meaning of the wave function is still not clear. Altogether, does the wave function represent a new kind of reality? This publication will solve the problem of the physical meaning of the wave function by investigating the relationship between the wave function and the theory of special relativity. It is shown that the wave function is determined by notion co-ordinate time of the special theory of relativity. Moreover, the result of this investigation suggests a new understanding of the wave function, according to which the wave function and co-ordinate time of the theory of special relativity are equivalent.

description: We present numerical simulations of high field transport in both suspended and deposited armchair graphene nanoribbon (A-GNR) on HfO2 substrate. Drift velocity in suspended GNR does not saturate at high electric field (F), but rather decreases, showing a maximum for F=10 kV/cm. Deposition on HfO2 strongly degrades the drift velocity by up to a factor of 10 with respect to suspended GNRs in the low-field regime, whereas at high fields drift velocity approaches the intrinsic value expected in suspended GNRs. Even in the assumption of perfect edges, the obtained mobility is far behind what expected in two-dimensional graphene, and is further reduced by surface optical phonons.

description: Im Jahr 1999 wurde die sogenannte „Altersrente für Frauen“ für die Jahrgänge ab 1952 abgeschafft. Dadurch erhöhte sich das frühestmögliche Renteneintrittsalter für viele Frauen schlagartig von 60 auf 63 Jahre. In der vorliegenden Studie werden anhand von Daten der deutschen Rentenversicherung und des Mikrozensus die Arbeitsmarkteffekte der Reform untersucht. Die Analysen zeigen im Durchschnitt positive Beschäftigungseffekte: Die Erwerbsquote der betroffenen Frauen steigt insgesamt um rund acht Prozentpunkte. Allerdings steigen auch Arbeitslosigkeit und Nichterwerbstätigkeit im selben Ausmaß. Der Beschäftigungseffekt geht vor allem darauf zurück, dass erwerbstätige Frauen länger arbeiten. Arbeitslose oder nichterwerbstätige Frauen wechseln durch die Erhöhung des Renteneintrittsalters kaum in Beschäftigung. Die Beschäftigungseffekte fallen für Frauen ohne hohe Bildung geringer aus. Der Wiedereingliederung von Arbeitslosen und Nichterwerbstätigen muss daher bei der künftigen Ausgestaltung der Altersgrenzen eine höhere Bedeutung zukommen. In diesem Zusammenhang sollte auch verstärkt in die Weiterbildung von älteren Menschen investiert werden.

Quantum Simulators at Negative Absolute Temperatures

Subjects: subject: Quantum Gases (cond-mat.quant-gas)

description: We propose that negative absolute temperatures in ultracold atomic clouds in optical lattices can be used to simulate quantum systems in new regions of phase diagrams. First we discuss how the attractive SU(3) Hubbard model in three dimensions can be realized using repulsively interacting 173-Yb atoms, then we consider how an antiferromagnetic S=1 spin chain could be simulated using spinor 87-Rb or 23-Na atoms. The general idea to achieve negative absolute temperatures is to reverse the sign of the external harmonic potential. Energy conservation in a deep optical lattice imposes a constraint on the dynamics of the cloud, which can relax toward a T<0 state. As the process is strongly non-adiabatic, we estimate the change of the entropy.

description: There are many ideas for developing shock-capturing schemes and their extension for all-speed flow. The representatives of them are Roe, HLL and AUSM families. In this paper, a uniform algorithm is proposed, which expresses three families in the same framework. The algorithm has explicit physical meaning, provides a new angel of understanding and comparing the mechanism of schemes, and may play a great role in the further research. As an example of applying the uniform algorithm, the low-Mach number behaviour of the schemes is analyzed. Then, a very clear and simple explanation is given based on the wall boundary, and a concise rule is proposed to judge whether a scheme has satisfied low-Mach number behaviour.

Bayesian methods for alleviating identification issues with applications in health and insurance areas
Creators: name: Xia, Chaoxiong
Publisher: name: University of British Columbia
Year: 2013

description: In areas such as health and insurance, there can be data limitations that may cause an identification problem in statistical modeling. Ignoring the issues may result in bias in statistical inference. Bayesian methods have been proven to be useful in alleviating identification issues by incorporating prior knowledge. In health areas, the existence of hard-to-reach populations in survey sampling will cause a bias in population estimates of disease prevalence, medical expenditures and health care utilizations. For the three types of measures, we propose four Bayesian models based on binomial, gamma, zero-inflated Poisson and zero-inflated negative binomial distributions. Large-sample limits of the posterior mean and standard deviation are obtained for population estimators. By extensive simulation studies, we demonstrate that the posteriors are converging to their large-sample limits in a manner comparable to that of an identified model. Under the regression context, the existence of hard-to-reach populations will cause a bias in assessing risk factors such as smoking. For the corresponding regression models, we obtain theoretical results on the limiting posteriors. Case studies are conducted on several well-known survey datasets. Our work confirms that sensible results can be obtained using Bayesian inference, despite the nonidentifiability caused by hard-to-reach populations. In insurance, there are specific issues such as misrepresentation on risk factors that may result in biased estimates of insurance premiums. In particular, for a binary risk factor, the misclassification occurs only in one direction. We propose three insurance prediction models based on Poisson, gamma and Bernoulli distributions to account for the effect. By theoretical studies on the form of posterior distributions and method of moment estimators, we confirm that model identification depends on the distribution of the response. Furthermore, we propose a binary model with the misclassified variable used as a response. Through simulation studies for the four models, we demonstrate that acknowledging the misclassification improves the accuracy in parameter estimation. For road collision modeling, measurement errors in annual traffic volumes may cause an attenuation effect in regression coefficients. We propose two Bayesian models, and theoretically confirm that the gamma models are identified. Simulation studies are conducted for finite sample scenarios.

Spontaneous Emission Spectra and Quantum Light-Matter Interactions from a Strongly-Coupled Quantum Dot Metal-Nanoparticle System

description: We investigate the quantum optical properties of a single photon emitter coupled to a finite-size metal nanoparticle using a photon Green function technique that rigorously quantizes the electromagnetic fields. We first obtain pronounced Purcell factors and photonic Lamb shifts for both a 7-nm and 20-nm radius metal nanoparticle, without adopting a dipole approximation. We then consider a quantum-dot photon emitter positioned sufficiently near to the metal nanoparticle so that the strong coupling regime is possible. Accounting for non-dipole interactions, quenching, and photon transport from the dot to the detector, we demonstrate that the strong coupling regime should be observable in the far-field spontaneous emission spectrum, even at room temperature. The emission spectra show that the usual vacuum Rabi doublet becomes a rich spectral triplet or quartet with two of the four peaks anticrossing, which survives in spite of significant non-radiative decays. We discuss the emitted light spectrum and the effects of quenching for two different dipole polarizations.

Gauge theory one-loop amplitudes and the BCFW recursion relations

description: We calculate gauge theory one-loop amplitudes with the aid of the complex shift used in the Britto-Cachazo-Feng-Witten (BCFW) recursion relations of tree amplitudes. We apply the shift to the integrand and show that the contribution from the limit of infinite shift vanishes after integrating over the loop momentum, by a judicious choice of basis for polarization vectors. This enables us to write the one-loop amplitude in terms of on-shell tree and lower point one-loop amplitudes. Some of the tree amplitudes are forward amplitudes. We show that their potential singularities do not contribute and the BCFW recursion relations can be applied in such a way as to avoid these singularities altogether. We calculate in detail $n$-point one-loop amplitudes for $n=2,3,4$, and outline the generalization of our method to $n>4$.

description: We report tests of local position invariance based on measurements of the ratio of the ground state hyperfine frequencies of 133Cs and 87Rb in laser-cooled atomic fountain clocks. Measurements extending over 14 years set a stringent limit to a possible variation with time of this ratio: d ln(nu_Rb/nu_Cs)/dt=(-1.39 +/- 0.91)x 10-16 yr-1. This improves by a factor of 7.7 over our previous report (H. Marion et al., Phys. Rev. Lett. 90, 150801 (2003)). Our measurements also set the first limit to a fractional variation of the Rb/Cs ratio with gravitational potential at the level of c^2 d ln(nu_Rb/nu_Cs)/dU=(0.11 +/- 1.04)x 10^-6, providing a new stringent differential redshift test. The above limits equivalently apply to the fractional variation of the quantity alpha^{-0.49}x(g_Rb/g_Cs), which involves the fine structure constant alpha and the ratio of the nuclear g-factors of the two alkalis. The link with variations of the light quark mass is also presented together with a global analysis combining with other available highly accurate clock comparisons.

description: Abstract
A good National Health System supports health development goals. Formal health services are all services that are part of the regular health care system, such as medical services, nursing services, and physiotherapy. Informal health services are all the concepts and rituals involved in voluntary assistance, traditional medicine, ethnic rituals and customs and alternative medicine. Acupuncture health services are included in informal health services. This type of research approach is normative juridical legal research with empirical research. The research data was obtained by interviewing sources at the Jakarta Health Office, especially the Directorate General of Public Health in charge of Traditional health workers. In qualitative data analysis, data is taken from any source with various data collection techniques (triangulation), inductive in nature, namely an analysis based on the data obtained, then developed into a hypothesis. The inductive method is used to find answers to the problems found in the Minister of Health Regulation and seen from justice as a citizen. The results of the study found that the legal theory used as a legal basis or ratio legis (the Reason and Purpose for making law) for regulating the legal reconstruction of Acupuncture Therapist Health Workers is the Theory of Justice proposed by Aristotle. The best legal principles for the implementation of legal protection for Acupuncture Therapists and Clients based on Pancasila, namely: The principle of nor maleficence (no harm), Beneficience (doing something good), Confidentiality (confidentiality), Justice (fairness), and the Principle of Fidelity (respect for promises to others). The concept of regulation based on the law for Acupuncture Therapists based on Health Law, in the form of a regulation that can provide legal certainty that is fair to Acupuncture Therapists as Traditional Health Workers.
