description: We experimentally explore the phenomenon of electron tunneling across a modulated tunneling barrier which is created between an STM tip and an Au film deposited on a vibrating piezo surface. Measurements of the time series of the quantum mechanical tunneling current across the modulating barrier show large fluctuations. Analysis of the average work done in establishing tunneling current in finite time interval shows a distribution of both positive and negative work events. The negative work events suggest tunneling against the bias voltage direction. We show that these distributions obey the Gallavotti Cohen Non-equilibrium Fluctuation Relations (GC-NEFR) valid for systems driven through a dissipating environment. Typically, while the GC-NEFR has been shown for non -equilibrium classical systems we show its validity for the quantum mechanical tunneling process too. The GC-NEFR analysis also gives us a way to measure the dissipation present in this quantum tunneling system. We propose the modulated barrier behaves like a lossy scattering medium for the tunneling electrons resulting in a tendency to randomize of the tunneling process.

Continuity, change and ethnic identity in 18th century Pennsylvania red earthenware: An archaeological and ethnohistorical study
Creators: name: Gibble, Patricia Ellen
Publisher: name: American University
Year: 2023

description: This dissertation focuses on examining the stylistic, functional and symbolic roles of 18th century Pennsylvania red earthenware by achieving three objectives. First, analysis of archaeological red earthenware data enables construction of a taxonomic framework for describing and classifying 18th century Pennsylvania red earthenwares. Second, comparison of intersite red earthenware assemblages allows for the delineation of processual trends in redware styles and function. Third, red earthenware assemblages are examined to discover implicit symbolic meaning in 18th century contexts that are signified by decorative embellishments and discrete morphology. The typological system organized in this inquiry was based on the work of Turnbaugh (1983) and provides a systematic framework for describing and classifying redware data from archaeological assemblages. This systemization was applied to quantify redware materials recovered from six 18th century historical archaeological excavations situated in southeastern Pennsylvania region. In order to reveal consistencies or evolutionary change in the colonial Pennsylvania redware tradition over space and time, this study compared characteristic morphological and style attributes of redware vessels and sherds from the entire 18th century period. Comparison of the resulting processual data enabled delineation of datable redware attributes to specific period in the 18th century. Analyses of redware proposed in this dissertation also lays the foundation for future comparisons of 18th century redware data to extant 19th century redware assemblages. In addition this research attempts to define various European ethnic influences on the nascent Pennsylvania redware tradition and suggests inferences regarding the emic meaning of this utilitarian ware for early colonial citizens. Defining anthropological meaning for 18th century redware from Pennsylvania contexts is based on three theoretical post-processual perspectives. First, a social construction of the past is completed to define social relationships and ethnic conflict in the fledgling Pennsylvania province. This is accomplished through a survey of pertinent ethno-historical documents to better understand social relations for Pennsylvania immigrants. Second, meaning ascribed Pennsylvania redware is proposed by employing post-modern theories of hegemony, resistance and boundary maintenance. Third, material culture and in particular redware is viewed as symbolic evidence of the active and recursive roles all multicultural groups played in creating an incipient American culture.

description: We study possible quantum phases of the Heisenberg antiferromagnet on the planar pyrochlore lattice, also known as the checkerboard lattice or the square lattice with crossings. It is assumed that the exchange coupling on the square-lattice-links is not necessarily the same as those along the crossing links. When all the couplings are the same, this model may be regarded as a two dimensional analog of the pyrochlore antiferromagnet. The large-N limit of the Sp($N$) generalized model is considered and the phase diagram is obtained by analyzing the fluctuation effects about the $N \to \infty$ limit. We find a topologically-ordered $Z_2$-spin-liquid phase in a narrow region of the phase diagram as well as the plaquette-ordered and staggered spin-Peierls phases as possible quantum-disordered paramagnetic phases.

Legislative control, bureaucratic characteristics, and discretion: The shaping of policy outcomes in state welfare bureaucracies
Creators: name: Hogue, Henry B.
Publisher: name: American University
Year: 2023

description: As the scope and complexity of the United States government grew during the twentieth century, elected officials responded by increasingly delegating the refinement and application of policy to administrative entities. The exercise of discretion by public administrators that is necessarily part of the resulting implementation process is subject to legislative, judicial, and executive constraints. Nonetheless, discretionary decision making in government bureaucracies further shapes elected officials' policy intentions. The present study investigates outcomes resulting from bureaucratic discretion using the case of Aid to Families with Dependent Children (AFDC). During the fourteen years prior to its end in 1996, political leaders increasingly favored work requirements and tighter program rules as ways to move able-bodied adults off the program rolls and into the workforce, and state welfare bureaucracies were called upon to implement these policy goals. This research focuses on state-level outcome measures that reflect levels of applicant access, participant termination, and work requirement enforcement. Models based on two bodies of theory are developed to explain these outcomes. The legislative control model holds that discretionary decision making is shaped by the beliefs and actions of elected officials. The bureaucratic factors model suggests that characteristics of agencies and their environments also systematically influence decisions and outcomes. These two models are tested empirically to investigate the relation between these forces and outcomes in bureaucracies with high levels of worker-citizen contact. Pooled time series analysis is used to analyze data from the fifty states from 1982 to 1995. Findings provide mixed support for the legislative control model. More liberality in state government is positively related to both higher application approval rates and lower termination rates. Stringent reform measures appear to exert their intended influence only on that outcome to which they were most closely related, moving recipients out of the program. The findings provide little support for the bureaucratic factors model. Unexpected significant findings are also discussed.

description: Does cultivating one crop secure more food than cultivating five crops for smallholder farmers in developing countries? How does farmers risk aversion affect crop diversification and food security choices at the household level? The effect of risk preference on crop diversification has been widely studied. It is unclear, however, how risk aversion, crop diversity, and food security are linked in a causal chain. This article investigates (i) the effect of crop diversification on food security and (ii) the direct effect of risk aversion on food security without a bias from crop diversification. Using the causal chain empirical strategy (Acharya et al., 2016), I estimate the direct effect of risk aversion. In using our unique experimental data collected in rural Ethiopia, our result shows the new evidence: (i) a negative effect of crop diversification on household food security and (ii) a positive direct effect of household head risk aversion on household food security. The contribution of this article consists of two parts. First, it develops the first theoretical framework to show the causal chains of risk aversion, crop diversity, and food security by adapting Sandmo s (1971) model. Second, this article provides the original evidence that crop diversity decreases food security. Acknowledgement : I am very grateful to Marc Bellemare and Terry Hurley for their comments and suggestions on earlier versions of the manuscript.

description: In the field of digital signal processing, the function of a filter is to remove unwanted parts of the signal such as random noise that is also undesirable. To remove noise from the speech signal transmission or to extract useful parts of the signal such as the components lying within a certain frequency range, filters are necessary. Filters are broadly used in signal processing and communication systems in applications such as channel equalization, noise reduction, radar, audio processing, speech signal processing, video processing, biomedical signal processing that is noisy ECG, EEG, EMG signal filtering, electrical circuit analysis and analysis of economic and financial data. In this paper, three types of infinite impulse response filter i.e. Butterworth, Chebyshev type I and Elliptical filter have been discussed theoretically and experimentally. Butterworth, Chebyshev type I and elliptic low pass, high pass, band pass and band stop filter have been designed in this paper using MATLAB Software. The impulse responses, magnitude responses, phase responses of Butterworth, Chebyshev type I and Elliptical filter for filtering the speech signal have been observed in this paper. Analyzing the Speech signal, its sampling rate and spectrum response have also been found.

description: As a part of an on-going program to explore the signature of p-modes in solar-like stars by means of high-resolution absorption lines pectroscopy, we have studied four stars (alfaCMi, etaCas A, zetaHer A and betaVir). We present here new results from two-site observations of Procyon A acquired over twelve nights in 1999. Oscillation frequencies for l=1 and l=0 (or 2) p-modes are detected in the power spectra of these Doppler shift measurements. A frequency analysis points out the dificulties of the classical asymptotic theory in representing the p-mode spectrum of Procyon A.

description: This study examined the relationship between self-esteem, mood, and body image dissatisfaction among female undergraduates. Based upon their performance on the Index of Self Esteem (Hudson, 1992), participants were divided into self-esteem groups (high and moderate self-esteem). Participants were also randomly assigned to dysphoric or neutral mood induction groups. The effects of being overweight were controlled for by having Body Mass Index (BMI) as a covariate in all analyses. There were overall effects of self esteem and mood on the attitudinal and perceptual aspects of body image dissatisfaction. When compared with participants in neutral mood conditions, those in the dysphoric mood conditions demonstrated more negative affective and cognitive appraisals of their bodies and they demonstrated wider discrepancies between their estimates of current and ideal body size regardless of self-esteem level. Relative to participants with higher levels of self-esteem, participants with lower levels of self-esteem were likely to have more negative thoughts and feelings about their bodies and they were likely to have a wider discrepancy between their estimates of current and ideal body size, regardless of mood, There was an overall effect of mood on estimates of ideal body size, with participants in dysphoric conditions preferring a thinner ideal body size than those in neutral conditions. There was an overall effect of self-esteem on estimates of current body size, with participants having lower levels of self-esteem providing larger estimates of current body size. The results suggest that self-esteem and dysphoric: mood influence the perceptual aspect of body image in separate and distinct ways that serve to create overall dissatisfaction by widening the discrepancy between estimates of current and ideal body size.

 Camila Formigoni e Breno Floriz: microfone de mão, duas vozes, interpretando o poema “Casulo” (05 minutos) Ela disse:  - Quero ficar em um casulo! O Canhoto respondeu: - Mas não fica em casulo quem não é de casulo! Chorando e soluçando ela retrucou: - Preciso desse casulo! Não quero me tornar uma borboleta, me contendo em ser pupa. Está de bom tamanho.  O Canhoto então, com um ar de deboche soltou: - Para quem quer viver em um mundo justo, o casulo não é morada.  Com a voz rouca pelo choro, tornou a dizer: - O mundo não é justo, seu Canhoto! Um casulo meu seria ideal para uma pupa desorientada e cheia de conflitos.  Nem lagarta, nem borboleta. Isso parece ótimo. Não acha?  - Mas Chorona, nós viemos ao mundo para torná-lo mais justo.  - Sou sensível, mas esperta! Estamos aqui porque, por acaso, nascemos. Ponto! A vida tem começo, meio e fim. Meu fim será como pupa, comecei como um ovo e meu término vai ocorrer no meio.  Canhoto, muito pensativo sobre quais seriam suas próximas palavras. Não poderia deixá-la em um casulo até o fim do meio. Todo cuidadoso disse: - Nesse "meio de vida" estamos aqui, para torná-lo justo. Alguns para mudanças, outros para linearidade. Chorona, você é muito boba! Você já é borboleta. Os dois se abraçaram. Ela finalizou: - Sou lagarta. Preciso me alimentar e em breve estarei ausente, envolta em meu casulo. Seu teimoso! Eles riram juntos e abraçados ele chorou olhando para a lua, pensando em como Chorona era em alguns momentos lagarta e em outros uma borboleta, mas, nunca havia sequer imaginado sua ausência, em um casulo.  Canhoto percebeu que agora tinha um toque de Chorona, e isso era irreversível, sua ausência apertava seu peito tanto que a saudade escorre pelos olhos.

description: Most Malawians directly depend on cereal production. Smallholder farmers in central Malawi are affected by declining soil fertility, especially because of Nitrogen depletion, due to crop harvest removals, soil erosion and leaching. The consequence is declining productivity and food insecurity. Legume intercropping is promoted in the tropics to replenish soil fertility. The importance of legumes include: the potential to improve soil fertility, improve nutrition to humans and income source for the smallholder farmers. This study evaluate the financial implications on smallholder farmers regarding the implementation of BNF (Biological Nitrogen Fixation) and inoculant technologies in current production systems. It focused on specific districts in Malawi: Ntcheu, Dedza, Mchinji, Salima and Kasungu. Gross margins increased for all the crops and all the districts after the adoption of the legume technologies. Intercropping system helps the farmers minimize risk against total crop failure and maximize cultivation per area. This lessens the challenges of small farms to some extent. The results indicate that farmers benefit financially from legume technologies. The gain from the inclusion of legume technology is, however, indicative of the low yield levels before the adoption. The legume technologies can contribute to productive and sustainable agricultural systems for the smallholder farmers in Malawi.

Giovanni Battista Giorgini: Designing the Future

description: This paper aims to highlight the history of Giovanni Battista Giorgini, “The Father of Italian Fashion”. Thanks to Giorgini, Italian Fashion becomes famous all over the world. Fashion journalist Elisa Vittoria Massai, one of the era’s most authoritative analysts of custom and economics and a guest at the 12 February 1951 Villa Torrigiani show, wrote: “By 1957, Italy was the leading European supplier of fabrics and clothing items to the U.S. Italy had surpassed both England and France. It is an absolute certainty that this would not have been possible had the Palazzo Pitti events, which were of incalculable promotional and advertising value, not been held with a seasonal cadence and had Giorgini’s professionalism as a commission agent and representative of the best-placed of the American stores not convinced competing agents and stores to jump in. The incredible success story, almost a fairy tale, of Italian fashion abroad comes clear in just a few numbers. Exports of wool and silk fabrics, for example, quintupled in six years; exports of knitwear products multiplied eightfold; knit outerwear alone about doubled. Womenswear sales jumped from a paltry 45 million lire in 1950 to one billion, 800 million in 1957. Leather footwear, from 208 million in 1950 to almost nineteen billion in 1957. Even Italian buttons rose in importance, with their two billion and change of 1957 over a value approaching zero in 1950.

description: We show how to significantly improve difference image analysis (DIA) of gravitationally lensed quasars over long periods of time using Gaia proper motions. DIA requires the subtraction of a reference image from the individual images of a monitoring campaign, using stars in the field to align the images. Since the proper motion of the stars can be of the same order as the pixel size during a several-year campaign, we use Gaia DR3 proper motions to enable a correct image alignment. The proper motion corrected star positions can be aligned by the ISIS package. DIA is carried out using the HOTPAnTS package. We apply point spread function (PSF) photometry to obtain light curves and add a proper motion correction of the PSF star to GALFIT. We apply our method to the light curves of the three gravitationally lensed quasars HE1104-1805, HE2149-2745 and Q2237+0305 in the R and V band, respectively, obtained using 1 m telescopes of the Las Cumbres Observatory from 2014 to 2022. We show that the image alignment and the determination of the lensed quasar positions is significantly improved by this method. The light curves of individual quasar images display intrinsic quasar variations and are affected by chromatic microlensing.

description: We construct entangled states of gluons that scatter exactly as if they were gravitons. Operationally, these objects implement the double copy at the level of the wave function. Our analysis begins with a general ansatz for a wave function characterizing gluons in two copies of ${\rm SU}(N)$ gauge theory. Given relatively minimal assumptions following from permutation invariance and dimensional analysis, the three- and four-particle wave functions generate scattering amplitudes that automatically coincide exactly with gravity, modulo normalization. For five-particle scattering the match is not automatic but imposing certain known selection rules on the amplitude is sufficient to uniquely reproduce gravity. The resulting amplitudes exhibit a color-dressed and permutation-invariant form of the usual double copy relations. We compute the entanglement entropy between the two gauge theory copies and learn that these states are maximally-entangled at large $N$. Moreover, this approach extends immediately to effective field theories, where Born-Infeld photons and Galileons can be similarly recast as entangled gluons and pions.

description: The variational quantum eigensolver (VQE) is an algorithm to find eigenenergies and eigenstates of systems in quantum chemistry and quantum many-body physics. The VQE is one of the most promising applications of near-term quantum devices to investigate such systems. Here we propose an extension of the VQE to calculate the nonadiabatic couplings of molecules in quantum chemical systems and Berry's phase in quantum many-body systems. Both quantities play an important role to understand the properties of a system beyond the naive adiabatic picture, e.g., nonadiabatic dynamics and topological phase of matter. We provide quantum circuits and classical post-processings to calculate the nonadiabatic couplings and Berry's phase. Specifically, we show that the evaluation of the nonadiabatic couplings reduces to that of expectation values of observables while that of Berry's phase also requires one additional Hadamard test. Furthermore, we simulate the photodissociation dynamics of a lithium fluoride molecule using the nonadiabatic couplings evaluated on a real quantum device. Our proposal widens the applicability of the VQE and the possibility of near-term quantum devices to study molecules and quantum many-body systems.

The range of this species is the southwestern USA, and northwestern Mexico. In the BCP, it has only been collected in the Gulf Coast in BCS (Timberlake 1964). We reviewed three specimens (2 ♂, 1 ♀), including one female and one male paratypes collected in the Gulf Coast October 1941 (CASC). See fig. 66.

description: The Gaussian phase noise of intensity time series is demonstrated to be drastically reduced when the raw voltage data are digitally filtered through an arbitrarily large number $n$ of orthornormal bandpass profiles (eigen-filters) sharing the same intensity bandwidth, and the resulting intensity series are co-added. Specifically, the relative noise variance of the summed series at the resolution of one coherence time or less, goes down with increasing $n$ as $1/n$, although (consistent with the radiometer equation) the advantage gradually disappears when the series is bin averaged to lower resolution. Thus the algorithm is designed to enhance the sensitivity of detecting transients that are smoothed out by time averaging and too faint to be visible in the noisy unaveraged time series, as demonstrated by the simulation of a weak embedded time varying signal of either a periodic nature or a fast and unrepeated pulse. The algorithm is then applied to a 10 minute observation of the pulsar PSR 1937+21 by the VLA, where the theoretical predictions were verified by the data. Moreover, it is shown that microstructures within the time profile are better defined as the number $n$ of filters used increases, and a periodic signal of period $1.86 \times 10^{-5}$~s ($53.9$~kHz) is discovered in the pulse profile. Lastly, we apply the algorithm to the first binary black hole merger detected by LIGO, GW150914. We find the SNR of the mean peak intensity increases as $\sqrt{n}$ and cross correlation of the event between the LIGO-Hanford-Livingston detector pair increases with filter order $n$.

description: Abstract This paper used choice experiment to assess households preferences for wastewater fed fish in Lima, Peru. The study considered four fish attributes, price, source, certification and information on additives. In total, 443 households participated in the field experiment. Results from the estimation of the random parameter logit (RPL) model in both the willingness to pay (WTP) and preference space showed that in general, households expressed positive preferences for fish raised in wastewater, freshwater and wild fish as well as certification and use of additives. Our findings show that household WTP for fish raised in the wild and in freshwater were positive and more robust as compared to WTP for wastewater fed fish which was influenced by factors such as certification. We find that households are willing to pay premiums of $0.69, $1.06 and $2.98 for wastewater, freshwater and wild fish respectively. We also find evidence to suggest that health and food safety concerns are the most important consideration in household preferences for wastewater fed fish amongst a set of perceptions variables examined in this study.

Endemic
[Holotype: CASC; ♂ Pescadero, Baja California, Mexico; October 8, 1941]
To our knowledge, this species is endemic to the BCP. We reviewed two males, including one paratype, collected in the same sampling event as the holotype, though it is in poor condition (CASC). Additionally, this species has also been reported in BC (Ayala et al. 1996). See fig. 67.

description: Food value chain businesses form alliances with horizontal and/or vertical partners to take collective action to either overcome or ameliorate chain failure, or to take advantage of new opportunities available due to innovations in products or processes. The desired outcomes from the collective action would not be possible to achieve if these businesses acted independently. While such alliances may take many forms, depending on degree of commitment and infrastructure linkages, they can often be considered to be clubs. Four mini-case studies are presented which demonstrate the breadth of past collective actions that have been undertaken by a substantial proportion of businesses in food value chains, two in Europe and two in Australia. These are (1) the Euro Pool System, (2) Global Standards certification in Europe and globally, (3) Meat Standards Australia, and (4) the East Gippsland Food Cluster in Australia. Each case study yields insights into the rationale of how businesses in different food value chains in different countries have acted as a club to use their joint resources to internalise positive innovation and coordination externalities that would not have been possible to achieve were these businesses to act independently.

description: This paper aims to highlight the main initiatives undertaken in the fashion sector in Italy and France between the Fifties and the Sixties of the twentieth century. Moreover, this concerning the high Italian fashion shows organized in Florence starting in February 1951 by Giovanni Battista Giorgini. Indeed, they marked the affirmation of Italy at an international level by registering a considerable interest on the part of American buyers. In this context, the role of Paris as the unique capital of fashion in the world is challenged for the first time. In this regard, Italian fashion and, in a more particular way, Florence became the leading competitor in conquering the American market for the fashion sector during the second post-war period. In particular, the text traces the public and private intervention plans for the coordination and promotion of the fashion system in both countries.

description: It is known that probing gravity in the submillimeter-micrometer range is difficult due to the relative weakness of the gravitational force. We intend to overcome this challenge by using extreme temporal precision to monitor transient events in a gravitational field. We propose a compressed ultrafast photography system called T-CUP to serve this purpose. We show that the T-CUP's precision of 10 trillion frames per second can allow us to better resolve gravity at short distances. We also show the feasibility of the setup in measuring Yukawa and power-law corrections to gravity which have substantial theoretical motivation.

description: The conditions for occurrence of the Efimov effect is briefly described using hyperspherical coordinates. The strength of the effective hyperradial $ρ^{-2}$ potential appearing for two or three large scattering lengths is computed and discussed as function of two independent mass ratios of the three constituent particles. The effect is by far most pronounced for asymmetric systems with three very different masses. One Efimov state may by chance appear in nuclei. Many states could be present for systems with one electron and two neutral atoms or molecules. Estimates of the number of states and their sizes and energies are given.

description: My research study seeks to discover how women of Color and White women victims of sexual harassment respond to their harassment. My study uses a sample of the data collected by the Department of Defense for their 1995 study of sexual harassment in the military. Hierarchical log-linear models were specified to test situational, personal, and organizational factors as predictors of responses. The results showed that situational factors are the most important predictors; the personal and organizational factors were not found to be significant predictors. Also, women of Color and White women were found to have differences in the ways they responded to sexual harassment.

description: The paper examines the drivers of rural poverty and their evolution in Bangladesh over the last two decades. It uses four rounds of a nationally representative rural longitudinal survey from 1988 and 2008. Using the standard Probit approach, the analysis identifies the factors most likely to distinguish, first, the households that managed to escape poverty from the chronic poor, and second, the households that fell into poverty relative to the never poor households to understand the characteristics likely to explain the causes of descent. The results indicate that different factors are associated with the ascent and descent of households, and they also vary over time periods. Labor endowment, land ownership, education, shocks, and non-farm work play nuanced roles in helping movers escape poverty or protecting the vulnerable from falling. For example, in the 2000s, the results show a heightened role for non-farm sources of income, helping households with better labor endowment escape poverty. Education, on the other hand, is associated with protecting the non-poor from falling over the same period. Improved connectivity is found to reduces vulnerability while migration and land ownership are associated with helping the movers as well as protecting the vulnerable.
