COMPARISON OF THE INVERTEBRATE ECOSYSTEM WITHIN AN INCREASINGLY URBAN ENVIRONMENT
Creators: name: Kirkpatrick, Kasie L.
Publisher: name: American University
Year: 2023

description: Ecologists understand the invaluable role invertebrates perform as primary producers of decomposition, nutrient recycling, and pollination, yet the effects of urbanization on their population ecology is lacking. While urban ecology has increased efforts to understand these phenomena, many in the field have suggested a new framework that lies somewhere between landscape and backyard ecology, finding a balance in the scales. In this study, invertebrates were collected across the District of Columbia at five random locations via pitfall and Berlese sampling techniques. Specimen identification, diversity indices, species richness, similarity estimates were performed on the collected population. Rank, abundance calculations and Class/Order proportions were performed at each research site. GIS was used to create and record collection sites, along with the attempt to establish specific environmental parameters believed to affect the invertebrate ecology. Population density and disturbance provided possible rank correlations to decline in species diversity for the given research areas and should be investigated further.

description: Using survey data, we document that foreign-owned institutions became more pessimistic than locally owned institutions about the strength of the Brazilian currency around the 2002 presidential elections. As a result of their relative pessimism, foreignowned institutions made larger forecast errors. Consistent with the emergence of their relative pessimism, foreign investors heavily sold Brazilian stocks and the Brazilian currency in futures markets ahead of the 2002 elections. Periods of stronger foreign sell-o§ were associated with larger equity price declines and larger depreciation of the Brazilian Real in spot and futures markets. These results are consistent with foreign investorsí lack of knowledge of Brazilian institutions contributing to the sharp depreciation of the Brazilian currency and stock market ahead of the 2002 presidential elections.

Year: 2010
Subjects: Financial Economics

description: This study exploits the reduction of weekly working hours from 48 to 45 occured in Chile in January 2005. We use this pure and exogenous policy change to identify the employment effects of such a policy. Our main contribution is that we overcome the problems of previous studies such as: selection between hours and employment, lack of identification strategy due to the joint implementation of policies and lack of crucial variables (like hourly wages and usual hours). Our results suggest no signiÖcant e§ects of a reduction of standard hours on employment transitions and a significant effect on hourly wages (i.e. wage compensation). These results are robust to several specifications.

description: Motivated by the recent interest in quantization of black hole area spectrum, we consider the area spectrum of Kerr and extremal Kerr black holes. Based on the proposal by Bekenstein and others that the black hole area spectrum is discrete and equally spaced, we implement Kunstatter's method to derive the area spectrum for the Kerr and extremal Kerr black holes. The real part of the quasinormal frequencies of Kerr black hole used for this computation is of the form $mΩ$ where $Ω$ is the angular velocity of the black hole horizon. The resulting spectrum is discrete but not as expected uniformly spaced. Thus, we infer that the function describing the real part of quasinormal frequencies of Kerr black hole is not the correct one. This conclusion is in agreement with the numerical results for the highly damped quasinormal modes of Kerr black hole recently presented by Berti, Cardoso and Yoshida. On the contrary, extremal Kerr black hole is shown to have a discrete area spectrum which in addition is evenly spaced. The area spacing derived in our analysis for the extremal Kerr black hole area spectrum is not proportional to $\ln 3$. Therefore, it does not give support to Hod's statement that the area spectrum $A_{n}=(4l^{2}_{p}ln 3)n$ should be valid for a generic Kerr-Newman black hole.

description:
Background: Ethnicity, cultural background, and geographic location differ significantly within the United States Hispanic/Latino population. These variations can greatly define diet and its relationship with cardiometabolic disease, thus influencing generalizability of results. Objectives: We aimed to examine nutrient-based food patterns (NBFPs) of Hispanic/Latino adults and their association with cardiometabolic risk factors (dyslipidemia, hypertension, obesity, diabetes) across 2 United States population-based studies with differing sampling strategies. Methods: Data were collected from Mexican or other Hispanic adult participants from 2007-2012 National Health and Nutrition Examination Survey (NHANES) (n = 3605) and 2007-2011 Hispanic Community Health Survey/Study of Latinos (HCHS/SOL, n = 14,416). NBFPs were derived using factor analysis on nutrient intake data estimated from 24-h dietary recalls and interpreted using common foods in which these nutrients are prominent. Cross-sectional associations between NBFPs (quintiles) and cardiometabolic risk factors, defined by clinical measures and self-report, were estimated using survey-weighted multivariable-adjusted logistic models, accounting for multiple testing. Results: Five NBFPs were identified in both studies: 1) meats, 2) grains/legumes, 3) fruits/vegetables, 4) dairy, and 5) fats/oils. Associations with cardiometabolic risk factors differed by NBFP and study. In HCHS/SOL, the odds of diabetes were lower for persons in the highest quintile of meats NBFP (odds ratio [OR]: 0.73; 95% confidence interval [CI]: 0.58, 0.92) and odds were higher for those in the lowest quintile of fruits/vegetables (OR: 0.71; 95% CI: 0.55, 0.93) compared to those in the third (moderate intake) quintile. Those in the fourth quintile of dairy NBFP had higher odds of hypertension than those in the third quintile (OR: 1.31; 95% CI: 1.01, 1.70). In NHANES, the odds of hypertension were higher for those in the fourth quintile of dairy (OR: 1.88; 95% CI: 1.10, 3.24) than those in the third quintile. Conclusions: Diet-disease relationships among Hispanic/Latino adults vary according to 2 population-based studies. These differences have research and practical implications when generalizing inferences on heterogeneous underrepresented populations.

description: Understanding the spreading of quantum correlations in out-of-equilibrium many-body systems is one of the major challenges in physics. For {\it isolated} systems, a hydrodynamic theory explains the origin and spreading of entanglement via the propagation of quasi-particle pairs. However, when systems interact with their surrounding much less has been established. Here we show that the quasi-particle picture remains valid for open quantum systems: while information is still spread by quasiparticles, the environment modifies their correlation and introduces incoherent and mixing effects. For free fermions with gain/loss dissipation we provide formulae fully describing incoherent and quasiparticle contributions in the spreading of entropy and mutual information. Importantly, the latter is not affected by incoherent correlations. The mutual information is exponentially damped at short times and eventually vanishes signalling the onset of a classical limit. The behaviour of the logarithmic negativity is similar and this scenario is common to other dissipations. For weak dissipation, the presence of quasiparticles underlies remarkable scaling behaviors.

description: Precision measurements of the cosmic microwave background by WMAP are believed to have established a flat $Λ$-dominated universe, seeded by nearly scale-invariant adiabatic primordial fluctuations. However by relaxing the hypothesis that the fluctuation spectrum can be described by a single power law, we demonstrate that an Einstein-de Sitter universe with {\em zero} cosmological constant can fit the data as well as the best concordance model. Moreover unlike a $Λ$-dominated universe, such an universe has no strong integrated Sachs-Wolfe effect, so is in better agreement with the low quadrupole seen by WMAP. The main problem is that the Hubble constant is required to be rather low: $H_0 \simeq 46$ km/s/Mpc; we discuss whether this can be consistent with observations. Furthermore for universes consisting only of baryons and cold dark matter, the amplitude of matter fluctuations on cluster scales is too high, a problem which seems generic. However, an additional small contribution ($Ω_X \sim 0.1$) of matter which does not cluster on small scales, e.g. relic neutrinos with mass of order eV or a `quintessence' with $w \sim 0$, can alleviate this problem. Such models provide a satisfying description of the power spectrum derived from the 2dF galaxy redshift survey and from observations of the Ly-$α$ forest. We conclude that Einstein-de Sitter models can indeed accommodate all data on the large scale structure of the Universe, hence the Hubble diagram of distant Type Ia supernovae remains the only {\em direct} evidence for a non-zero cosmological constant.

 Type species. Stromatopora proxilaminata Fagerstrom, 1961.
 Discussion. In the type species of Habrostroma, H. proxilaminatum (Fagerstrom, 1961), Prosh & Stearn (1996, p. 36) described the pachystele microstructure as “orthoreticular to clinoreticular” in longitudinal section, and as having a “cellular (=irregular microreticular)” microstructure, presumably the “acosmoreticular” type of Stock (1989) in tangential section. However, other writers have recognized the genus Habrostroma as exhibiting only acosmoreticular microstructure (see Stock, 1991, 1997; Webby et al., 1993). For comparative purposes, the genus Atopostroma, based on A. tuntouense Yang & Dong, 1979, has been described as exhibiting “orthoreticulate to clinoreticulate” microstructure (see Stearn, 1993, Stearn et al., 1999), but also in Stearn (1990, p. 498) and Stock (1997, p. 549), as only exhibiting a clinoreticular type of microstructure, as in Columnostroma and Coenostroma, respectively. In the present study, the species of Atopostroma show examples of both acosmoreticular and clinoreticular microstructural types; no orthoreticular types have been found.
 The diagnostic features of the two genera are as follows: Habrostroma typically has pachysteles that are shorter, more irregular, confined largely within “interlaminar” spaces (rarely superposed) and internally composed of an irregular network of acosmoreticulate skeletal material; and the pachystromes prominent but not thick, with one or more microlaminae, and sometimes microlaminalike dissepiments. Atopostroma, on the other hand, has pachysteles that are typically superposed, formed by upward and outward accretion to produce irregularly spread network of acosmoreticular to clinoreticulate skeletal material beneath successive, laterally extensive, microlaminae. The two described species H. alternum and A. protentum occur together in the Martins Well Limestone Member and are truly transitional forms, showing some features characteristic of each genus. Some consideration has been given to combining them, even treating them as different species of the one genus. However, between the mid-range and extremes of variation of the two species they are clearly representatives of different genera.

description: The present work analyzes the interaction between antitrust policy and intellectual property protection, with particular reference to the cases of refusal to supply, when it concerns ideas or inventions protected by an IP right. For this purpose, the paper preliminarily discusses the governing principles of antitrust policy on abuse of dominance and refusal to deal, as they have been implemented in the decisions of the EU Competition Authority, and it presents the specific issues related to the implementation of antitrust policy in the innovative industries. Then, the paper examines in particular the Microsoft Europe Case, as decided by the European Commission in 2004, focusing on the issue of the interoperability between the operating systems for personal computers and the operating systems for work group servers. The theoretical model, developed as an extension of the framework proposed by Choi and Stefanadis (2001) to the case of refusal to deal, suggests an explanation of the case, alternative to the one adopted by the Commission, if not necessarily in the final outcome of the decision, at least in the analytical arguments and in the dynamics of the market structure. In particular, we show that the refusal to supply the compatibility between the two complementary products was determined not only by the intention to leverage its dominant position to the adjacent market of server operating systems, but especially by the concern for keeping the monopoly on its core market, that is the one of PC operating system, given the future evolution of the software market, due to the diffusion of cloud computing.

description: A slab of negatively refracting material, thickness d, can focus an image at a distance 2d from the object. The negative slab cancels an equal thickness of positive space. This result is a special case of a much wider class of focussing: any medium can be optically cancelled by an equal thickness of material constructed to be an inverted mirror image of the medium, with, $ε$ and $μ$ reversed in sign. We introduce the powerful technique of coordinate transformation, mapping a known system into an equivalent system, to extend the result to a much wider class of structures including cylinders, spheres, and intersecting planes and hence show how to produce magnified images. All the images are perfect in the sense that both the near and far fields are brought to a focus and hence reveal sub wavelength details.

description: Much current research in functional magnetic resonance imaging (fMRI) employs multivariate machine learning approaches (e.g., support vector machines) to detect distributed spatial patterns from the temporal fluctuations of the neural signal. The aim of many studies is not classification, however, but investigation of multivariate spatial patterns, which pattern classifiers detect only indirectly. Here we propose a direct statistical measure for the existence of distributed spatial patterns (or spatial heterogeneity) applicable to fMRI datasets. We extend the univariate general linear model (GLM), typically used in fMRI analysis, to a multivariate case. We demonstrate that contrasting maximum likelihood estimations of different restrictions on this multivariate model can be used to estimate the extent of spatial heterogeneity in fMRI data. Under asymptotic assumptions inference can be made with reference to the χ 2 distribution. The test statistic is then assessed using simulated timecourses derived from real fMRI data followed by analyzing data from a real fMRI experiment. These analyses demonstrate the utility of the proposed measure of heterogeneity as well as considerations in its application. Measuring spatial heterogeneity in fMRI has important theoretical implications in its own right and may have potential uses for better characterising neurological conditions such as stroke and Alzheimer’s disease.

description: This thesis examines the psychological empowerment of female undergraduates taking introductory level science, technology, engineering, and math (STEM) classes. Using original Instagram messaging from women in the STEM field, this study analyzes how role models and belonging-based messaging affects women’s psychological empowerment. This thesis establishes a new operationalization of empowerment, measuring meaning, self-efficacy, and locus of control. While the Instagram interventions did not result in higher levels of empowerment as compared to the control condition, the belonging condition produced significantly lower levels of empowerment as compared to the role model condition. Similarly, those in the belonging condition reported significantly lower scores on the meaning subscale than did those in the role model condition.

description: This paper analyzes the rural-urban migration of families in the Bohemian region of Pilsen in 1900. Using a new 1300-family dataset from the 1900 population census I examine the role of children‘s education in rural-urban migration. I find that families migrated to the city such that the educational attainment of their children would be maximized and that there is a positive correlation between family migration and children being apprentices in urban areas. The results suggest that rural-urban migration was powered not only by the exploitation of rural-urban wage gaps but also by aspirations to engage in human capital investment.

description: This paper examines sustainable operations of brewpubs with a triple bottom line assessment applied to provide recommendations to the proposed AMS brewpub. Consisting of a social, environmental, and economical analysis, the triple bottom line assessment thoroughly examines the sustainability of this issue. Operations of the brewpub are broken up into six key areas, ingredients, recipes, brewing process, cleaning, packaging, and recycling spent grains after brewing with a triple bottom line analysis applied to each section. Our analysis shows that for each of the six sections, sustainable operations are attainable for all three of the indicators. Socially, sustainability is better for the people involved directly and indirectly with the brew pub, environmentally, sustainability does not have to involve social and economic compromises, and economically, sustainability will provide the opportunity to save money on operational costs in the long run. By implementing sustainable practices throughout the construction and operation of the brewpub, the AMS and the new SUB can become leaders in sustainable brewing.

description: An observer makes a number of observations of an industry producing a homogeneous good. Each observation consists of the market price, the output of individual firms and perhaps information on each firm’s production cost. We provide various tests (typically, linear programs) with which the observer can determine if the data set is consistent with the hypothesis that firms in this industry are playing a Cournot game at each observation. When cost information is wholly or partially unavailable, these tests could potentially be used to derive cost information on the firms. This paper is a contribution to the literature that aims to characterize (in various contexts) the restrictions that a data set must satisfy for it to be consistent with Nash outcomes in a game. It is also inspired by the seminal result of Afriat (and the subsequent literature) which addresses similar issues in the context of consumer demand, though one important technical difference from most of these results is that the objective functions of firms in a Cournot game are not necessarily quasiconcave.

description: We consider a codimension-one brane embedded in a gravity-dilaton bulk action, whose symmetries are compatible with T-duality along the space-like directions parallel to the brane, and the bulk time-like direction. The equations of motions in the string frame allow for a smooth background obtained by the union of two symmetric patches of AdS space. The Poincaré invariance of the solution appears to hold independently of the value of the brane vacuum energy, through a self-tuning property of the dilaton ground state. Moreover, the effective cosmology displays a bounce, at which the scale factor does not shrink to zero. Finally, by exploiting the T-duality symmetry, we show how to construct an ever-expanding Universe, along the lines of the Pre-Big Bang scenario.

description: The GlueX forward calorimeter is an array of 2800 lead glass modules that was constructed to detect photons produced in the decays of hadrons. A background to this process originates from hadronic interactions in the calorimeter, which, in some instances, can be difficult to distinguish from low energy photon interactions. Machine learning techniques were applied to the classification of particle interactions in the GlueX forward calorimeter. The algorithms were trained on data using decays of the $ω$ meson, which contain both true photons and charged particles that interact with the calorimeter. Algorithms were evaluated on efficiency, rate of false positives, run time, and implementation complexity. An algorithm that utilizes a multi-layer perceptron neural net was deployed in the GlueX software stack and provides a signal efficiency of 85% with a background rejection of 60% for an inclusive $π^0$ data sample for an intermediate quality constraint.

description: We study deformations of Landau-Ginzburg D-branes corresponding to obstructed rational curves on Calabi-Yau threefolds. We determine D-brane moduli spaces and D-brane superpotentials by evaluating higher products up to homotopy in the Landau-Ginzburg orbifold category. For concreteness we work out the details for lines on a perturbed Fermat quintic. In this case we show that our results reproduce the local analytic structure of the Hilbert scheme of curves on the threefold.

description: We introduce a methodology for analysing infinite horizon economies with two agents, one good, and incomplete markets. We provide an example in which an agent’s equilibrium consumption is zero eventually with probability one even if she has correct beliefs and is marginally more patient. We then prove the following general result: if markets are effectively incomplete forever then on any equilibrium path on which some agent’s consumption is bounded away from zero eventually, the other agent’s consumption is zero eventually–so either some agent vanishes, in that she consumes zero eventually, or the consumption of both agents is arbitrarily close to zero infinitely often. Later we show that (a) for most economies in which individual endowments are finite state time homogeneous Markov processes, the consumption of an agent who has a uniformly positive endowment cannot converge to zero and (b) the possibility that an agent vanishes is a robust outcome since for a wide class of economies with incomplete markets, there are equilibria in which an agent’s consumption is zero eventually with probability one even though she has correct beliefs as in the example. In sharp contrast to the results in the case studied by Sandroni (2000) and Blume and Easley (2006) where markets are complete, our results show that when markets are incomplete not only can the more patient agent (or the one with more accurate beliefs) be eliminated but there are situations in which neither agent is eliminated.

description: Many biological functions rely on the reshaping of cell membranes, in particular into nanotubes, which are covered in vivo by dynamic actin networks. Nanotubes are subject to thermal fluctuations, but the effect of these on cell functions is unknown. Here, we form nanotubes from liposomes using an optically trapped bead adhering to the liposome membrane. From the power spectral density of this bead, we study the nanotube fluctuations in the range of membrane tensions measured in vivo. We show that an actin sleeve covering the nanotube damps its high frequency fluctuations because of the network viscoelasticity. Our work paves the way for further studies on the effect of nanotube fluctuations in cellular functions.

description: The construction of a perfectly secure private quantum channel in dimension d is known to require 2 log d shared random key bits between the sender and receiver. We show that if only near-perfect security is required, the size of the key can be reduced by a factor of two. More specifically, we show that there exists a set of roughly d log d unitary operators whose average effect on every input pure state is almost perfectly randomizing, as compared to the d^2 operators required to randomize perfectly. Aside from the private quantum channel, variations of this construction can be applied to many other tasks in quantum information processing. We show, for instance, that it can be used to construct LOCC data hiding schemes for bits and qubits that are much more efficient than any others known, allowing roughly log d qubits to be hidden in 2 log d qubits. The method can also be used to exhibit the existence of quantum states with locked classical correlations, an arbitrarily large amplification of the correlation being accomplished by sending a negligibly small classical key. Our construction also provides the basic building block for a method of remotely preparing arbitrary d-dimensional pure quantum states using approximately log d bits of communication and log d ebits of entanglement.

description: The loss of qubits - the elementary carriers of quantum information - poses one of the fundamental obstacles towards large-scale and fault-tolerant quantum information processors. In this work, we experimentally demonstrate a complete toolbox and the implementation of a full cycle of qubit loss detection and correction on a minimal instance of a topological surface code. This includes a quantum non-demolition measurement of a qubit loss event that conditionally triggers a restoration procedure, mapping the logical qubit onto a new encoding on the remaining qubits. The demonstrated methods, implemented here in a trapped-ion quantum processor, are applicable to other quantum computing architectures and codes, including leading 2D and 3D topological quantum error correcting codes. These tools complement previously demonstrated techniques to correct computational errors, and in combination constitute essential building blocks for complete and scalable quantum error correction.

description: Interstellar turbulence has implications for the dispersal and mixing of the elements, cloud chemistry, cosmic ray scattering, and radio wave propagation through the ionized medium. This review discusses the observations and theory of these effects. Metallicity fluctuations are summarized, and the theory of turbulent transport of passive tracers is reviewed. Modeling methods, turbulent concentration of dust grains, and the turbulent washout of radial abundance gradients are discussed. Interstellar chemistry is affected by turbulent transport of various species between environments with different physical properties and by turbulent heating in shocks, vortical dissipation regions, and local regions of enhanced ambipolar diffusion. Cosmic rays are scattered and accelerated in turbulent magnetic waves and shocks, and they generate turbulence on the scale of their gyroradii. Radio wave scintillation is an important diagnostic for small scale turbulence in the ionized medium, giving information about the power spectrum and amplitude of fluctuations. The theory of diffraction and refraction is reviewed, as are the main observations and scintillation regions.

description: Vortex coherent structures on arrays of nonlinear oscillators joined by weak links into topologically nontrivial two-dimensional discrete manifolds have been theoretically studied. A circuit of nonlinear electric oscillators coupled by relatively weak capacitances has been considered as a possible physical implementation of such objects. Numerical experiments have shown that a time-monochromatic external force applied to several oscillators leads to the formation of long-lived and nontrivially interacting vortices in the system against a quasistationary background in a wide range of parameters. The dynamics of vortices depends on the method of "coupling" of the opposite sides of a rectangular array by links, which determines the topology of the resulting manifold (torus, Klein bottle, projective plane, Möbius strip, ring, or disk).

description: We investigate the problem of Nash implementation in the presence of “partially honest” individuals. A partially honest player is one who has a strict preference for revealing the true state over lying when truthtelling does not lead to a worse outcome (according to preferences in the true state) than that which obtains when lying. We show that when there are at least three individuals, the presence of even a single partially honest individual (whose identity is not known to the planner) can lead to a dramatic increase in the class of Nash implementable social choice correspondences. In particular, all social choice correspondences satisfying No Veto Power can be implemented. We also provide necessary and sufficient conditions for implementation in the two-person case when there is exactly one partially honest individual and when both individuals are partially honest. We describe some implications of the characterization conditions for the two-person case. Finally, we extend our three or more individual result to the case where there is an individual with an arbitrary small but strictly positive probability of being partially honest.
