description: This purpose of this project was to investigate the interrelationships between family structure, classroom stress, sense of belonging, and substance misuse in college students. Some outcomes of the study were an increased knowledge of substance misuse in college students and the impact of risk and protective factors on substance misuse. One model of family structure is the Circumplex Model of Family Systems. This model consists of three components: family cohesion, adaptability and communication fOIson, Russell, & Sprenkle, 1989). This research was conducted at Old Dominion University using 391 undergraduate college students, aged 18 - 25. It was hypothesized that students with families that are more extreme in cohesion and adaptability would have greater substance misuse and that increased satisfaction with their family would be associated with decreased substance use. Balanced families would have moderate levels of cohesion and adaptability. Classroom stress and sense of belonging were also predicted to have interrelationships with substance misuse. Gender differences in substance misuse were also examined. Specifically, males were predicted to have higher levels of substance misuse compared to females. Results showed that family cohesion was positively related to binge drinking. Family satisfaction was related positively to the substance misuse variables. The family type variable was predicted to have the least substance use at the balanced ranges of family types. Instead, results showed that the highest substance use was associated with the more functioning family type. Gender differences were in the direction predicted, with males using significantly more alcohol or drugs than females. Also, more alcohol related problems were associated with increased substance use. Many of the family variables had a protective relationship with college stress. Also, the classroom stress variable had positive correlations with substance misuse variables. These results could be attributed to limited range in the family variables. Also, all data were collected in the weeks following spring break, which may have resulted in a unique effect for substance misuse variables.

description: The dynamical structure of the atmosphere of Cepheids has been well studied in the optical. Several authors have found very interesting spectral features in the J band, but little data have been secured beyond 1.6 um. However, such observations can probe different radial velocities and line asymmetry regimes, and are able to provide crucial insights into stellar physics. Our goal was to investigate the infrared line-forming region in the K-band domain, and its impact on the projection factor and the k-term of Cepheids. We secured CRIRES observations for the long-period Cepheid l Car, with a focus on the unblended spectral line NaI2208.969 nm. We measured the corresponding radial velocities (by using the first moment method) and the line asymmetries (by using the bi-Gaussian method). These quantities are compared to the HARPS visible spectra we previously obtained on l Car. The optical and infrared radial velocity curves show the same amplitude (only about 3% of difference), with a slight radial velocity shift of about 0.5 +/- 0.3 km s^-1 between the two curves. Around the minimum radius (phase ~ 0.9) the visible radial velocity curve is found in advance compared to the infrared one (phase lag), which is consistent with an infrared line forming higher in the atmosphere (compared to the visible line) and with a compression wave moving from the bottom to the top of the atmosphere during maximum outward velocity. The asymmetry of the K-band line is also found to be significantly different from that of the optical line.

description: The theme of environmental preservation is recurrent in international concern about the climatic impacts that humanity has faced. The gradual increase of the global temperature is an important factor to be considered when analyzing any aspect of the environment, especially with regard to the healthy quality of life. In this sense, the objective of this research is to verify the possibility of the auxiliary tax law in the institute of Environmental sustainability and addressing the ICMS tax under the ecological bias, within the scope of the State of Amazonas. It is concluded that the ICMS-Ecological calls for positive behaviors on the part of the municipal power that can, through Environmental Education, stimulate positive behaviors of the citizens of the State of Amazonas, generating environmental protection and, consequently, improvement of the quality of life in the State. The deductive method was used, how many to the means the research was the bibliographical and, how many to the ends, qualitative.

description: The chargino $\tildeχ^\pm_{1,2}$ system can be reconstructed completely in $e^+e^-$ collisions. By measuring the total cross sections and the asymmetries with polarized beams in $e^+e^-\to\tildeχ_i^+ \tildeχ_j^- [i,j=1,2]$, the chargino masses and the gaugino-higgsino mixing angles of these states can be determined very accurately. If only the lightest charginos $\tildeχ_1^\pm$ are kinematically accessible, transverse beam polarization is needed to determine the mixing angles unambiguously. From these observables the fundamental SUSY parameters can be derived: the SU(2) gaugino mass $M_2$, the modulus and the cosine of the CP-violating phase of the higgsino mass parameter $μ$, and $\tanβ= v_2/v_1$, the ratio of the vacuum expectation values of the two neutral Higgs doublet fields. [The remaining two-fold ambiguity of the phase can be resolved by measuring the normal polarization of the charginos.]

description: Many historians reject quantitative methods as inappropriate to understanding past societies. This article argues that no sharp distinction between qualitative and quantitative concepts can be drawn, as almost any concept used to describe a past society is implicitly quantitative. Many recent advances in understanding have been achieved by deriving quantitative evidence from qualitative evidence, using the two dialectically, and indexing them against other quantitative findings from the same population. We show that this triangulation method can be extended to many apparently qualitative sources. Despite its successes, the potential of turning qualitative into quantitative evidence has only just begun to be exploited.

description: Vortex breakdown phenomena in the axial vortices is an important feature which occurs frequently in geophysical flows (tornadoes and hurricanes) and in engineering flows (flow past delta wings, Von-Kerman vortex dynamo). We analyze helicity for axisymmetric vortex breakdown and propose a simplified formulation. For such cases, negative helicity is shown to conform to the vortex breakdown. A model problem has been analyzed to verify the results. The topology of the vortex breakdown is governed entirely by helicity density in the vertical plane. Our proposed methodology may be regarded as the prototype for identifying and characterize the breakdowns/eye in more complicated large-scale flows such as tornadoes/hurricanes.

description: Photosynthetic eukaryotes show a remarkable variability in photosynthesis, including large differences in light harvesting proteins and pigment composition. In vivo circular spectropolarimetry enables us to probe the molecular architecture of photosynthesis in a non-invasive and non-destructive way and, as such, can offer a wealth of physiological and structural information. In the present study we have measured the circular polarizance of several multicellular green, red and brown algae and higher plants, which show large variations in circular spectropolarimetric signals with differences in both spectral shape and magnitude. Many of the algae display spectral characteristics not previously reported, indicating a larger variation in molecular organization than previously assumed. As the strengths of these signals vary by three orders of magnitude, these results also have important implications in terms of detectability for the use of circular polarization as a signature of life.

description: Using a perturbative model for diffractive interactions, we derive an expression for the polarized diffractive structure function $g_1^D$ in the high energy limit. This structure function is given by the interference of diffractive amplitudes with polarized and unpolarized exchanges. For the polarized exchange we consider both two-gluon and quark-antiquark amplitudes. The polarized diffractive amplitude receives sizable contributions from non-strongly ordered regions in phase space, resulting in a double logarithmic enhancement at small $x$. The resummation of these double logarithmic terms is outlined. We also discuss the transition from our perturbative expression to the nonperturbative region. A first numerical estimate indicates that the perturbative contribution to the spin asymmetry is substantially larger than the nonperturbative one.

description: Low energy scattering and bound state properties of the πN, ππand Kπsystems are studied as coupled channel problems using inversion potentials of phase shift data. In a first step we apply the potential model to explain recent measurements of pionic hydrogen shift and width. Secondly, predictions of the model for pionium lifetime and shift confirm a well known and widely used effective range expression. Thirdly, as extension of this confirmation, we predict an unexpected medium effect of the pionium lifetime which shortens by several orders of magnitude. The σmeson shows a narrow resonance structure as a function of the medium modified mass with the implication of being essentially energy independent. Similarly, we see this medium resonance effect realized for the Kπsystem. To support our findings we present also results for the ρmeson and the Δ(1232) resonance.

We show that the spatial inhomogeneities of that class of solutions can be attributed to underlying Grassmannian pseudo-degrees of freedom. Such an interpretation may also be applied to FP solutions in three and more dimensions.

description: Two important technological aspects of the Big data paradigm have been the emergence of massive
scale Online Social Networks (OSNs) (such as Facebook and Twitter), and the rise of the
open data movement that has resulted in the creation of richly structured online datasets, such as
Wikipedia, Citeseer and the US federal government’s data.gov initiative. The examples of OSNs
and online datasets cited above share the common feature that they can be thought of as Online
Information Graphs, in the sense that the information embedded in them has a natural graph
structure.
In this thesis, we consider using this underlying Online Information Graph as a statistical prior
to enhance classification accuracy of some hard machine learning problems. Specifically, we look
at instances where the graph is undirected and propose using the graph to define an Ising -
Markov Random Field (MRF) prior. To begin with, we validate the Ising prior using a novel hypothesis
testing framework based approach. Having validated the Ising prior, we demonstrate its
utility by showcasing Network Aided Vector classification (NAC) of real world data from fields
as varied as vote prediction in the US senate, movie earnings level classification (using IMDb
dataset) and county crime-level classification (using the US census data). We then consider a
special case of the classification problem which involves Network Aided Detection (NAD) of a
global sentiment in an OSN. To this end, we consider Latent Sentiment (LS) detection as well as
Majority Sentiment detection. We analyze the performance of the trivial sentiment detector for
LS detection using a novel communications-oriented viewpoint, where we view the underlying
network as providing a weak channel code that transmits one bit of information (the binary
sentiment) and perform error exponent analysis for various underlying graph models. We also
address the problem of optimal Maximum A posterior Probability (MAP) detection of majority
sentiment in the highly noisy labels weak network effect (NW) scenario, deriving the High Temperature
(HT) expansion formula for the partial partition function of the Ising model using the
code-puncturing idea from coding theory and then proposing an approximate MAP detector that
outperforms the Maximum Likelihood (ML) detector and the trivial detector.

description: Eleven nearby (<300 pc), short-period (50-130 days) asymptotic giant branch (AGB) stars were observed in the CO J = (2-1) line. Detections were made towards objects that have evidence for dust production (Ks-[22] >~ 0.55 mag; AK Hya, V744 Cen, RU Crt, alpha Her). Stars below this limit were not detected (BQ Gem, eps Oct, NU Pav, II Hya, CL Hyi, ET Vir, SX Pav). Ks-[22] colour is found to trace mass-loss rate to well within an order of magnitude. This confirms existing results, indicating a factor of 100 increase in AGB-star mass-loss rates at a pulsation period of ~60 days, similar to the known "superwind" trigger at ~300 days. Between ~60 and ~300 days, an approximately constant mass-loss rate and wind velocity of ~3.7 x 10^-7 solar masses per year and ~8 km/s is found. While this has not been corrected for observational biases, this rapid increase in mass-loss rate suggests a need to recalibrate the treatment of AGB mass loss in stellar evolution models.

description: Many have questioned the empirical relevance of the Calvo-Yun model. This paper adds a term structure to three widely studied macroeconomic models (Calvo-Yun, hybrid and Svensson). We back out from observations on the yield curve the underlying macroeconomic model that most closely matches the level, slope and curvature of the yield curve. With each model we trace the response of the yield curve to macroeconomic shocks. We assess the fit of each model against the observed behaviour of interest rates and find limited support for the Calvo-Yun model in terms of fit with the observed yield curve, we find some support for the hybrid model but the Svensson model performs best.

description: We presents a global model linking individual country vector error-correcting models in which domestic variables are related to country-specific variables as an approximate solution to a global common factor model. The model is estimated for 26 economies. It provides a theoretical framework where the GVAR is derived as an approximation to a global unobserved common factor model, and using average pair-wise cross-section error correlations, the approach is shown to be quite effective in dealing with common factor interdependencies and international co-movements of business cycles. In addition to generalised impulse response functions, we propose an identification scheme to derive structural impulse responses. We focus on identification of shocks to the US economy, particularly the monetary policy shocks, and consider the time profiles of their effects on the euro area. To this end we include the US model as the first country model and consider alternative orderings of the US variables.

description: We consider the dynamics of electrons in combined strong laser and Coulomb fields. Under a timescale separation condition, we reduce this dynamics to a guiding-center framework. More precisely, we derive a hierarchy of models for the guiding-center dynamics based on averaging over the fast motion of the electron using Lie transforms. The reduced models we obtain describe well the different ionization channels, in particular, the conditions under which an electron is rescattered by the ionic core or is directly ionized. The comparison between these models highlights the models which are best suited for a qualitative and quantitative agreement with the parent dynamics.
The Mystique of Central Bank Speak

Subjects: subject: Classification-JEL: E52, E58, D82
subject: Transparency, monetary policy, communication, transparency misperceptions.

description: Despite the recent trend toward greater transparency of monetary policy, in many respects mystique still prevails in central bank speak. This paper shows that the resulting perception of ambiguity could be desirable. Under the plausible assumption of imperfect common knowledge about the degree of central bank transparency, economic outcomes are affected by both the actual and perceived degree of transparency. It is shown that actual transparency is beneficial, while it may be useful to create the perception of opacity. The optimal communication strategy for the central bank is to provide clarity about the inflation target and to communicate information about the output target and supply shocks with perceived ambiguity. In this respect, the central bank benefits from sustaining transparency misperceptions, which helps to explain the mystique of central bank speak.

description: To describe ultrarelativistic heavy-ion collisions we construct a three-fluid hydrodynamical model. In contrast to one-fluid hydrodynamics, it accounts for the finite stopping power of nuclear matter, i.e. for nonequilibrium effects in the early stage of the reaction. Within this model, we study baryon dynamics in the BNL-AGS energy range. For the system Au+Au we find that kinetic equilibrium between projectile and target nucleons is established only after a time $t_{CM}^{eq}\approx 5~fm/c\simeq 2R_{Au}/γ_{CM}$. Observables which are sensitive to the early stage of the collision (like e.g. nucleon flow) therefore differ considerably from those calculated in the one-fluid model.

description: Period estimation is an important task in the classification of many variable astrophysical objects. Here we present GRAPE: Genetic Routine for Astronomical Period Estimation, a genetic algorithm optimised for the processing of survey data with spurious and aliased artefacts. It uses a Bayesian Generalised Lomb-Scargle (BGLS) fitness function designed for use with the Skycam survey conducted at the Liverpool Telescope. We construct a set of simulated light curves using both regular and Skycam survey cadence with four types of signal: sinusoidal, sawtooth, symmetric eclipsing binary and eccentric eclipsing binary. We apply GRAPE and a BGLS periodogram to this data and show that the performance of GRAPE is superior to the periodogram on sinusoidal and sawtooth light curves with relative hit rate improvement of 18.2% and 6.4% respectively. The symmetric and eccentric eclipsing binary light curves have similar performance on both methods. We show the Skycam cadence is sufficient to correctly estimate the period for all of the sinusoidal shape light curves although this degrades with increased non-sinusoidal shape with sawtooth, symmetric binary and eccentric binary light curves down by 20%, 30% and 35% respectively. The runtime of GRAPE demonstrates that light curves with more than 500-1000 data points achieve similar performance in less computing time. The GRAPE performance can be matched by a frequency spectrum with an oversampled fine-tuning grid at the cost of almost doubling the runtime. Finally, we propose improvements which will extend this method to the detection of quasi-periodic signals and the use of multiband light curves.

description: Demographic behaviour is influenced not just by attributes of individuals but also by characteristics of the communities in which those individuals live. A project on ‘Economy, Gender, and Social Capital in the German Demographic Transition’ is analyzing the longterm determinants of fertility by carrying out family reconstitutions of three Württemberg communities (Auingen, Ebhausen, and Wildberg) between c. 1558 and 1914. A related project on ‘Human Well-Being and the “Industrious Revolution”: Consumption, Gender and Social Capital in a German Developing Economy, 1600-1900’ is using marriage and death inventories to investigate how consumption interacted with production and demographic behaviour in two of these communities. This paper examines the historical, political, institutional, geographical, and economic attributes of the communities analyzed in these projects and discusses their potential effects. The aim is to generate testable hypotheses and relevant independent variables for subsequent econometric analyses of demographic behaviour.
On the control of Rydberg state population with realistic femtosecond laser pulses

description: We investigate computationally a method for ultrafast preparation of alkali metal atoms in their Rydberg states using a three-dimensional model potential in the single active electron approximation. By optimizing laser pulse shapes that can be generated with modern waveform synthesizers, we propose pulses for controlling the population transfer from the ground state to a preselected set of Rydberg states. Dynamical processes under the optimized pulses are shown to be much more complicated than in the traditional optical two-photon preparation of Rydberg states.
Pair Tunneling in Semiconductor Quantum Dots

description: We propose here a model for the pair tunneling states observed by Ashoori and co-workers (Phys. Rev. Lett. {\bf 68}, 3088 (1992)) in GaAs quantum dots. We show that while GaAs is a weakly-polar semiconductor, coupling to optical phonons is sufficiently strong to mediate a negative-U pairing state. The physical potential in which the two electrons are bound can be composed of a Si impurity and a parabolic well that originates from the potential created by the $δ-$dopants in the backing layer of the dot. Such a pair state breaks up at moderate magnetic field strengths ($\approx$ 2 T), as is seen experimentally, and is unstable when the confining radius of the dot is smaller than $\approx 400$Å.

Mechanical feedback from black hole accretion as an energy source of core-collapse supernova explosions

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: According to the traditional scenario for core-collapse supernovae, the core of the collapsing star forms a neutron star and its gravitational energy release sends out a shockwave into the stellar envelope. However, in a significant number of numerical simulations, the shock stalls and the star cannot be exploded successfully, especially for a massive, compact star. We consider an alternative scenario that with mass fallback, the collapsing star forms a black hole in the center, surrounded by a dense, hot accretion disk, which blows out an intense outflow (wind). The kinetic energy of the wind may result in a successful stellar explosion. With an improved version of the formulism in Kohri et al. (2005) who studied neutron star accretion of minor fallback, we study this disk wind-driven explosion by calculating the accretion history for a suite of pre-SN stellar models with different initial surface rotational velocities, masses and metallicities, and by comparing the disk wind energy with the binding energy of the infalling stellar envelope. We show that the most promising models to be exploded successfully by this new channel are those relatively compact pre-SN stars with relatively low metallicities and not too low specific angular momenta. The total energies of the explosions are $\sim 10^{51-52}$ergs, and a more massive progenitor may produce a more energetic explosion.

Constraints on Phases of Supersymmetric Flavour Conserving Couplings

description: In the unconstrained MSSM, we reanalyze the constraints on the phases of supersymmetric flavour conserving couplings that follow from the electron and neutron electric dipole moments (EDM). We find that the constraints become weak if at least one exchanged superpartner mass is >O(1 TeV) or if we accept large cancellations among different contributions. However, such cancellations have no evident underlying symmetry principle. For light superpartners, models with small phases look like the easiest solution to the experimental EDM constraints. This conclusion becomes stronger the larger is the value of $\tanβ$. We discuss also the dependence of $ε_K$, $Δm_B$ and $b\to sγ$ decay on those phases.

Linear Extrapolation of Ultrarelativistic Nucleon-Nucleon Scattering to Nucleus-Nucleus Collisions
Creators: name: Jeon, Sangyong

Publisher: name: arXiv
Year: 1997
Subjects: subject: Nuclear Theory (nucl-th)

description: We use a Glauber-like approach to describe very energetic nucleus-nucleus collisions as a sequence of binary nucleon-nucleon collisions. No free parameters are needed: all the information comes from simple parametrizations of nucleon-nucleon collision data. Produced mesons are assumed not to interact with each other or with the original baryons. Comparisons are made to published experimental measurements of baryon rapidity and transverse momentum distributions, negative hadron rapidity and transverse momentum distributions, average multiplicities of pions, kaons, hyperons, and antihyperons, and zero degree energy distributions for sulfur-sulfur collisions at 200 GeV/c per nucleon and for lead-lead collisions at 158 GeV/c per nucleon. Good agreement is found except that the number of strange particles produced, especially antihyperons, is too small compared with experiment. We call this model LEXUS: it is a baseline linear extrapolation of ultrarelativistic nucleon-nucleon scattering to heavy ion collisions.

Social capital and collusion: the case of merchant guilds

description: Merchant guilds have been portrayed as ‘social networks’ that generated beneficial ‘social capital’ by sustaining shared norms, effectively transmitting information, and successfully undertaking collective action. This social capital, it is claimed, benefited society as a whole by enabling rulers to commit to providing a secure trading environment for alien merchants. But was this really the case? We develop a new model of the emergence, rise and eventual decline of European merchant guilds which explores the collusive relationship between rulers and guilds, and calls into question the prevailing positive view of merchant guilds. We then confront the model’s predictions with the available historical data. The empirical evidence strongly support our model and refutes existing theories. Our findings show that merchant guilds used their social capital for socially harmful as well as beneficial ends.

description: The discovery of FeO$_{2}$ containing more oxygen than hematite (Fe$_{2}$O$_{3}$) that was previously believed to be the most oxygen rich iron compounds, has important implications on the study of the deep lower mantle compositions. Compared to other iron compounds, there are limited reports on FeO$_{2}$ making studies of its physical properties of great interest in fundamental condensed matter physics and geoscience. Even the oxidation state of Fe in FeO$_{2}$ is the subject of debate in theoretical works and there have not been reports from experimental electronic and magnetic properties measurements. Here, we report the pressure-induced spin state transition from synchrotron experiments and our computational results explain the underlying mechanism. Using density functional theory and dynamical mean field theory, we calculated spin states of Fe with volume and Hubbard interaction $U$ change, which clearly demonstrate that Fe in FeO$_{2}$ consists of Fe(II) and peroxide O$_{2}^{2-}$. Our study suggests that localized nature of both Fe 3$d$ orbitals and O$_{2}$ molecular orbitals should be correctly treated for unveiling the structural and electronic properties of FeO$_{2}$.
