description: A multiplier bootstrap procedure for construction of likelihood-based congidence sets is considered for ginite samples and a possible model misspecification. Theoretical results justify the bootstrap consistency for a small or moderate sample size and allow to control the impact of the parameter dimension p: the bootstrap approximation works if p3=n is small. The main result about bootstrap consistency continues to apply even if the underlying parametric model is misspecified under the so called Small Modeling Bias condition. In the case when the true model deviates significantly from the considered parametric family, the bootstrap procedure is still applicable but it becomes a bit conservative: the size of the constructed confidence sets is increased by the modeling bias. We illustrate the results with numerical examples for misspecified constant and logistic regressions.

description: Using an optically-unbiased selection process based on the HIPASS neutral hydrogen survey, we have selected a sample of 83 spatially isolated, gas-rich dwarf galaxies in the southern hemisphere with cz between 350 and 1650 km s-1, and with R-band luminosities and HI masses less than that of the Small Magellanic Cloud. The sample is an important population of dwarf galaxies in the local Universe, all with ongoing star formation, and most of which have no existing spectroscopic data. We are measuring the chemical abundances of these galaxies, using the Integral Field Spectrograph on the ANU 2.3m telescope, the Wide Field Spectrograph (WiFeS). This paper describes our survey criteria and procedures, lists the survey sample, and reports on initial observations.

description: A drop impacting on a solid surface deforms before the liquid makes contact with the surface. We directly measure the time evolution of the air layer profile under the droplet using high-speed color interferometry, obtaining the air layer thickness before and during the wetting process. Based on the time evolution of the extracted profiles obtained at multiple times, we measure the velocity of air exiting from the gap between the liquid and the solid, and account for the wetting mechanism and bubble entrapment. The present work offers a tool to accurately measure the air layer profile and quantitatively study the impact dynamics at a short time scale before impact.

description: The market for retail financial products (e.g. investment funds or insurances) is marred by information asymmetries. Clients are not well informed about the quality of these products. They have to rely on the recommendations of advisors. Incentives of advisors and clients may not be aligned, when fees are used by financial institutions to steer advice. We experimentally investigate whether voluntary contract components can reduce the con ict of interest and increase truth telling of advisors. We compare a voluntary payment upfront, an obligatory payment upfront, a voluntary bonus afterwards, and a three-stage design with a voluntary payment upfront and a bonus after. Across treatments, there is significantly more truthful advice when both clients and advisors have opportunities to reciprocate. Within treatments, the frequency of truthful advice is significantly higher when the voluntary payment is large.

description: We propose an analog model for quantum gravity effects using nonlinear dielectrics. Fluctuations of the spacetime lightcone are expected in quantum gravity, leading to variations in the flight times of pulses. This effect can also arise in a nonlinear material. We propose a model in which fluctuations of a background electric field, such as that produced by a squeezed photon state, can cause fluctuations in the effective lightcone for probe pulses. This leads to a variation in flight times analogous to that in quantum gravity. We make some numerical estimates which suggest that the effect might be large enough to be observable.

description: Many business people such as farmers and financial investors are affected by indirect losses caused by scarce or abundant rainfall. Because of the high potential of insuring rainfall risk, the Chicago Mercantile Exchange (CME) began trading rainfall derivatives in 2011. Compared to temperature derivatives, however, pricing rainfall derivatives is more difficult. In this article, we propose to model rainfall indices via a flexible type of distribution, namely the normal-inverse Gaussian distribution, which captures asymmetries and heavy-tail behaviour. The prices of rainfall futures are computed by employing the Esscher transform, a wellknown tool in actuarial science. This approach is flexible enough to price any rainfall contract and to adjust theoretical prices to market prices by using the calibrated market price of risk. This empirical analysis is conducted with U.S. precipitation data and CME futures data providing first results on the market price of risk for rainfall derivatives.

description: The re-use of research data is an integral part of research practice in the social and economic sciences. To find relevant data, researchers need adequate search facilities. However, a thematic search for data is made more difficult by inconsistent or missing semantic indexing of data at the level of social science concepts (e.g., representing the theory language). Either the data is not documented at a granular level, or primary investigators use their ad-hoc terminology to describe their data. Consequently, researchers have to make great efforts to find relevant or comparable data. From the user's perspective, the lack of theory language in data documentation impedes effective data searches Because there is currently no semantic model for indexing the data content, the specific challenge for improving data search lies in establishing concept-based indexing of research data. Research infrastructures need technology for the harmonized semantic indexing of their research data. The LORD concept registry aims at closing this gap by developing a registry of sociological and economic concepts and, following the FAIR principles, making this concept registry generally available to the scientific community. As a first step, we developed a basic data model for the Concept Registry using United Modeling Language (UML). All links between are created and managed in the form of so-called RDF triples. Second, an annotation application allows for linking specific questions/variables to concepts. The application also includes the SKOS-compliant thesaurus "Thesaurus Social Sciences" but can be extended to other resources like ELSST. We illustrate the application of the concept registry with examples from three survey programmes (German Socio-Economic Panel, German General Social Survey, National Academics Panel Study). The initial focus is on variables and questions with overlapping content in the three surveys, as they form a sound basis for cross-linking with concepts.

description: Scalar fields, strongly coupled to matter, can be present in nature and still be invisible to local experiments if they are subject to a screening mechanism. The symmetron is one such mechanism which relies on restoration of a spontaneously broken symmetry in regions of high density to shield the scalar fifth force. We have investigated structure formation in the symmetron model by using N-body simulations and find strong observable signatures in both the linear and nonlinear matter power spectrum and on the halo mass function. The mechanism for suppressing the scalar fifth force in high density regions is also found to work very well.

description: International trade has been playing an extremely significant role in China over the last 20 years. This paper is aimed at investigating and understanding the relationship between China’smacro-economy and oil price fromthis newperspective. We find strong evidence to suggest that the increase of China’s price level, resulting fromoil price shocks, is statistically less than that of its main trade partners’. This helps us to understand the confused empirical results estimated within the SVAR framework and sheds light on recent data. More specifically, as for the empirical results, we find China’s output level is positively correlated with the oil price, and oil price shocks slightly appreciate the RMB against the US dollar. Positive correlation between China’s output and oil price shocks presumably results from the drop in China’s relative price induced by oil price shocks, which is inclined to stimulate China’s goods and service exports. The slight appreciation of the RMB could be justified by the drop in China’s relative price, which is indicated by economic theory. Moreover, constructing a simple model, our new perspective also helps us to understand the recent fact that together with the dramatic surge of the world oil price, while the oil imports of the other major countries (especially the largest oil import country US) in the world steadily decline or remain stable, China’s oil imports, in contrast, have kept rising steeply since the year 2004.

description: Both Virginia Woolf and George Eliot have been the subject of a great deal of feminist criticism, and in the process have frequently been attacked for not taking up in their fiction the feminist concerns that both have presented in some of their non-fiction. In examining Middlemarch and To the Lighthouse , this thesis takes the position that Eliot and Woolf in fact did much toward subverting patriarchal conceptions of women particularly through their treatment of the chief ideal of femininity during the Victorian age: the Angel in the House , who was eulogized in Coventry Patmore's poem of the same name. The Angel was by definition submissive and selfless or ego-less; lacking ambition and accepting her inherent inferiority to the male, she found her total expression and fulfillment in the family. The question of whether woman was inherently submissive and self-sacrificing and in all ways inferior to man was especially crucial to the female artist , for the Angel was the very antithesis of the artistic character: the Angel's chief characteristic is selflessness; to write at all is to claim a subject position at odds with the notion of selflessness. This thesis contends that through revision , subversion and deconstruction, Eliot and Woolf probe the limits and possibilities of the Angel as an ideal of womanhood, revealing not only commitment to the major feminist concerns of their day, but even subversion of dominant patriarchal constructs. The thesis also explores the ways in which Eliot and Woolf's strategies vary because of the different assumptions about identity and the nature of reality associated with realism and modernism.

description: The approximation of a stationary time-series by finite order autoregressive (AR) and moving averages (MA) is a problem that occurs in many applications. In this paper we study asymptotic behavior of the spectral density of finite order approximations of wide sense stationary time series. It is shown that when the on the spectral density is non-vanishing in $[-π,π]$ and the covariance is summable, the spectral density of the approximating autoregressive sequence converges at the origin. Under additional mild conditions on the coefficients of the Wold decomposition it is also shown that the spectral densities of both moving average and autoregressive approximations converge in $L_2$ as the order of approximation increases.

description: The root of Combretum dolichopetalum (Combreatacea) is used in ethnomedicine for the management of diabetes mellitus. Though some compounds have been isolated from it, the antidiabetic principles have not been identified. The present study was designed to evaluate the chemical constituents from the root of C. dolichopetalum with a view to identifying the antidiabetic principles. The constituents include the alkaloids, echinulin (1) and arestrictin B (2), the terpenoids, arjunolic acid (3) and 4'-dihydrophaseic acid (4) as well as the phenolic acids, ellagic acid (5) and 3, 4, 3'-tri-O-methylellagic acid (6). Twenty eight mice (in seven groups, n = 4) were made diabetic using alloxan monohydrate (i.p., 120 mg/kg) and treated orally with either the vehicle (control group), any of the constituents or glibenclamide (standard drug). The fasting blood glucose of the diabetic animals was monitored for nine hours. Results showed that all the chemical constituents (1-6) exhibited significant (p < 0.05) antidiabetic activity comparable to glibenclamide. The alkaloids exhibited the most profound antidiabetic activity. The present study has thus identified the antidiabetic principles of C. dolichopetalum root as echinulin, arestrictin B, arjunolic acid, 4'-dihydrophaseic acid, ellagic acid and 3, 4, 3'-tri-O-methylellagic acid. The study has further validated the ethnomedicinal use of the root of C. dolichopetalum in diabetes.

description: The observed relationship between stellar mass and effective radius for early type galaxies, pointed out by many authors, is interpreted in the context of Clausius' virial maximum theory. In this view, it is strongly underlined that the key of the above mentioned correlation is owing to the presence of a deep link between cosmology and the existence of the galaxy Fundamental Plane. Then the ultimate meaning is: understanding visible mass - size correlation and/or Fundamental Plane means understanding how galaxies form. The mass - size relationship involves baryon (mainly stellar) mass and its typical dimension related to the light, but it gets memory of the cosmological mass variance at the equivalence epoch. The reason is that the baryonic component virializes by sharing virial energy in about equal amount between baryons and dark matter, this sharing depending, in turn, on the steepness of the dark matter distribution. The general strategy consists in using the two-component tensor virial theorem for determining the virialized baryonic configurations. A King and a Zhao density profile are assumed for the inner baryonic and the outer dark matter component, respectively, at the end of the relaxation phase. All the considerations are restricted to spherical symmetry for simplicity. The effect of changing the dark-to-baryon mass ratio, m, is investigated inside a LambdaCDM scenario. A theoretical mass - size relation is expressed for the baryonic component, which fits fairly well to the data from a recently studied galaxy sample. Finally, the play of intrinsic dispersion on the mass ratio, m, is discussed in the light of the cusp/core problem and some consequences are speculated about the existence of a limit, m_l, expected by the theory.

description: The white dwarf mass-radius relationship is fundamental to modern astrophysics. It is central to routine estimation of DA white dwarf masses derived from spectroscopic temperatures and gravities. It is also the basis for observational determinations of the white dwarf initial-final mass relation. Nevertheless, definitive and detailed observational confirmations of the mass-radius relation (MRR) remain elusive due to a lack of sufficiently accurate white dwarf masses and radii. Current best estimates of masses and radii allow only broad conclusions about the expected inverse relation between masses and radii in degenerate stars. In this paper we examine a restricted set of 12 DA white dwarf binary systems for which accurate (1) trigonometric parallaxes, (2) spectroscopic effective temperatures and gravities, and (3) gravitational redshifts are available. We consider these three independent constraints on mass and radius in comparison with an appropriate evolved MRR for each star. For the best-determined systems it is found that the DA white dwarfs conform to evolved theoretical MRRs at the 1-σ to 2-σ level. For the white dwarf 40 Eri B (WD0413-077) we find strong evidence for the existence of a "thin" hydrogen envelope. For other stars improved parallaxes will be necessary before meaningful comparisons are possible. For several systems current parallaxes approach the precision required for the state-of-the-art mass and radius determinations that will be obtained routinely from the Gaia mission. It is demonstrated here how these anticipated results can be used to firmly constrain details of theoretical mass-radius determinations.

description: Classical regression methods treat covariates as a vector and estimate a corresponding vector of regression coefficients. Modern applications in medical imaging generate covariates of more complex form such as multidimensional arrays (tensors). Traditional statistical and computational methods are proving insufficient for analysis of these high-throughput data due to their ultrahigh dimensionality as well as complex structure. In this article, we propose a new family of tensor regression models that efficiently exploit the special structure of tensor covariates. Under this framework, ultrahigh dimensionality is reduced to a manageable level, resulting in efficient estimation and prediction. A fast and highly scalable estimation algorithm is proposed for maximum likelihood estimation and its associated asymptotic properties are studied. Effectiveness of the new methods is demonstrated on both synthetic and real MRI imaging data.

description: In the field of the Jacobian conjecture it is well-known after Druzkowski that from a polynomial "cubic-homogeneous" mapping we can build a higher-dimensional "cubic-linear" mapping and the other way round, so that one of them is invertible if and only if the other one is. We make this point clearer through the concept of "pairing" and apply it to the related conjugability problem: one of the two maps is conjugable if and only if the other one is; moreover, we find simple formulas expressing the inverse or the conjugations of one in terms of the inverse or conjugations of the other. Two nontrivial examples of conjugable cubic-linear mappings are provided as an application.

description: Gravitational tidal forces acting on the virtual e+ e- cloud surrounding a photon endow spacetime with a non-trivial refractive index. This has remarkable properties unique to gravitational theories including superluminal low-frequency propagation, in apparent violation of causality, and amplification of the renormalized photon field, in apparent violation of unitarity. Using the geometry of null congruences and the Penrose limit, we illustrate these phenomena and their resolution by tracing the history of a photon as it falls into the near-singularity region of a black hole.

description: An advisor is supposed to recommend a financial product in the best interest of her client. However, the best product for the client may not always be the product yielding the highest commission to the advisor. Do advisors nevertheless provide truthful advice? If not, will a voluntary or obligatory upfront payment by clients induce more truthful advice? According to the results, both types of payment lead to more truthful advice. More generally, in a senderreceiver game with con ict of interest, an upfront payment to the sender by the receiver improves information transmission.

description: This article describes the conditions and working processes of the Department of Military Cemeteries established at the Headquarters of the Imperial and Royal Army of Austria in Cracow, 1916-1918. Particular attention is paid to the designs prepared by the architect Dušan Jurkovič (1868-1947). The domain of commemorative architecture represented a novel task to the architect, formerly renowned for his emphatic style synthesizing vernacular architecture and Art Nouveau. Leaning on his close acquaintance with the traditions of Carpathian wooden architecture, he thoroughly studied the language of classical monumental architecture and developed a distinctive and poetic style for his sepulchral ensembles. This paper elucidates the architect’s development, his considerations, and the typology of his cemeteries and monuments, explaining also the significance of Jurkovič’s Galician experience for his later career.

A relevant question persists regarding the evolution of the power tail coefficient. We have developed a methodology to meaningfully track the power law coefficient over time, when a country experience population growth. A relevant dynamic law, Gibrat's law, is empirically tested in this connection. We argue that these empirical findings for India goes in contrast with the findings in case of China, another country with population growth but monolithic political system.

description: The essay retraces the biographical events of the sculptor Giulio Cartarè, last pupil of Gian Lorenzo Bernini. In addition to tracking down the artist’s baptism act on March 27, 1642, thanks to several unpublished archival resources it was possible to ascertain the French origin of his family, present in Rome since 1610 with his grandfather Nicolas. Through the examination of parish registers of St. Andrea delle Fratte, it was possible to clarify the dynamics of first contacts between Giulio Cartarè and Bernini’s workshop.

description: This action research project examines the role classroom culture and discourse can play on student learning, with a focus on female students. A sixth grade science classroom was evaluated through analysis of two videotaped astronomy lessons. The classroom environment utilized qualitative methods to examine teacher and student interactions, student and student interactions, and classroom environment. The research project began in response to a previous research project which found that after completing an astronomy unit male students not only out preformed female students, but female students lost gains in several area. Findings suggested that there may be a connection between the classroom discourse and microculture and the girls’ low performance.

description: In the symmetron mechanism, the fifth force mediated by a coupled scalar field (the symmetron) is suppressed in high-density regions due to the restoration of symmetry in the symmetron potential. In this paper we study the background cosmology and large scale structure formation in the linear perturbation regime of the symmetron model. Analytic solutions to the symmetron in the cosmological background are found, which agree well with numerical results. We discuss the effect of the symmetron perturbation on the growth of matter perturbation, in particular the implications of the brief period of tachyonic instability caused by the negative mass squared of the symmetron during symmetry breaking. Our analysis and numerical results show that this instability has only very small effects on the growth of structures on sub-horizon scales, and even at horizon scales its influence is not as drastic as naively expected. The symmetron fifth force in the non-tachyonic regime does affect the formation of structure in a nontrivial way which could be cosmologically observable.

description: We present a new method, Non-Stationary Forward Flux Sampling, that allows efficient simulation of rare events in both stationary and non-stationary stochastic systems. The method uses stochastic branching and pruning to achieve uniform sampling of trajectories in phase space and time, leading to accurate estimates for time-dependent switching propensities and time-dependent phase space probability densities. The method is suitable for equilibrium or non-equilibrium systems, in or out of stationary state, including non-Markovian or externally driven systems. We demonstrate the validity of the technique by applying it to a one-dimensional barrier crossing problem that can be solved exactly, and show its usefulness by applying it to the time-dependent switching of a genetic toggle switch.

Principals' and School Food Service Workers' Perceptions of the Implementation of the Community Eligibility Provision
Creators: name: Moore, Shirlena M.
Publisher: name: University of Kentucky
Year: 2016
Subjects: subject: Nutrition

description: Over the years, participation in the School Breakfast Program (SBP) has increased, on both state and national levels. The Community Eligibility Provision (CEP) offers free breakfast to all students regardless of income. The purpose of this study was to examine the perception of principals and school food service workers regarding the benefits, barriers, attitudes and beliefs about the implementation of the CEP. A survey was sent to principals and school food service workers. The majority of the participants were satisfied overall with the CEP and the nutritional quality of foods served for breakfast. The majority of the participants did not see any major barriers to CEP implementation; however, they acknowledged several benefits. Future research should combine qualitative and quantitative methods to explore these perceptions and gather information on why participants feel the way they do in regards to CEP implementation.

description: The period of the 1920's is crucial to understanding both the impact of the First World War in Europe as well as the origins of the Second World War. Although practically all of the documents from this period have been subject to historical scrutiny for many years, there is still much disagreement among historians as to the place of the Weimar Republic in both German and European history since 1919. Many historians see the period of the Weimar Republic in a negative light. It is viewed either as a time of respite, in which Germany recovered from the First World War and rearmed for a new campaign of aggression, or as a tragic decade in German history, which never made a difference in the long run. Other historians have taken a more positive viewpoint of the German Republic from 1919 to 1933. They claim that it was a legitimate attempt by responsible Germans to shake off the mistakes of the past and rebuild Germany within a European system based on cooperation and reconciliation. Gustav Stresemann, Germany's foreign minister from 1923 to 1929, was one of the central figures in Germany's struggle to obtain respect and equality among the Powers of Europe after World War One. Unfortunately, much of what has been written about Stresemann paints him either as a "good European" and the champion of peace or as an untrustworthy manipulator whose achievements were obscured by the events which followed after his death. The result is an often biased and unrealistic portrait of Stresemann during the 1920's. It is my intention to re-examine Stresemann's career, but without beginning with the assumption that the Second World War was "inevitable" and without arguing that Stresemann must necessarily be depicted as the antithesis of Hitler. The most important documents which I consulted during the course of this thesis were the English and German editions of Stresemann's private diaries, letters and papers as well as the unpublished and unedited Stresemann papers or Nachlass. Stresemann's papers clearly demonstrate what his aims were during the 1920's and show the extent to which he _ was involved in the revival of Germany as a Great Power in Europe. I am also indebted to various secondary sources for their respective contribution to the ideas developed throughout this thesis, among which were Marvin Edwards' Stresemann and the Greater Germany; Henry Turner's Gustav Stresemann and the Politics of the Weimar Republic; Christoph Kimmich's Germany and the League of Nations; and P.M.H. Bell's The Origins of the Second World War in Europe.

Skill Mismatch in Equilibrium Unemployment
Creators: name: Bachmann, Ronald

Subjects: subject: 330 Wirtschaft

description: We analyse the effect of skill mismatch in a search model of equilibrium unemployment with risk-neutral agents, endogenous job destruction, and two-sided ex-ante heterogeneity. First, we examine the interaction of labour market institu- tions and skill mismatch. We find that skill mismatch changes the results obtained in a model with ex ante homogeneity. Second, we analyse the interaction of skill mismatch and labour market institutions for the di®erence in the labour market experience of continental Europe on the one hand and the US on the other hand. We find that within-group skill mismatch cannot explain the rise in unemployment in Europe relative to the US. This result is due to the endogeneity of job destruction and stands at odds with previous findings in the literature. We can, however, confirm the fact that unemployment benefits potentially play a beneficial role by providing a subsidy to search. Generally, we argue that in search models with fixed match characteristics, job destruction should be endogenised in order to take account of heterogeneous decision rules.

Process and Technical Vulnerabilities: 6 Key Takeaways from a Chemical Plant Disaster

description: Near the end of a warm summer day, an engineer monitors the flow of process materials at a chemical manufacturing plant. On his screen, the engineer watches a valve switch from open to closed. He's confused. It's not supposed to close -- not on its own. The plant is under cyber attack, and, as the engineer soon learns, the closing valve is just the first failure. Organizations frequently (and appropriately) spend a lot of time and effort on the technical aspects of operations. But the catastrophe about to unfold was caused just as much by weaknesses in plans and procedures. In this blog post, I’ll walk through the technical vulnerabilities -- and the perhaps more surprising process maturity vulnerabilities -- that led to the disaster, talk about why they’re so important for any organization, and suggest some tried-and-true mitigations.
