description: We investigate the statistics of fluctuations in a classical stochastic network of nodes joined by connectors. The nodes carry generalized charge that may be randomly transferred from one node to another. Our goal is to find the time evolution of the probability distribution of charges in the network. The building blocks of our theoretical approach are (1) known probability distributions for the connector currents, (2) physical constraints such as local charge conservation, and (3) a time-scale separation between the slow charge dynamics of the nodes and the fast current fluctuations of the connectors. We derive a stochastic path integral representation of the evolution operator for the slow charges. Once the probability distributions on the discrete network have been studied, the continuum limit is taken to obtain a statistical field theory. We find a correspondence between the diffusive field theory and a Langevin equation with Gaussian noise sources, leading nevertheless to non-trivial fluctuation statistics. To complete our theory, we demonstrate that the cascade diagrammatics, recently introduced by Nagaev, naturally follows from the stochastic path integral. We extend the diagrammatics to calculate current correlation functions for an arbitrary network. One primary application of this formalism is that of full counting statistics (FCS). We stress however, that the formalism is suitable for general classical stochastic problems as an alternative to the traditional master equation or Doi-Peliti technique. The formalism is illustrated with several examples: both instantaneous and time averaged charge fluctuation statistics in a mesoscopic chaotic cavity, as well as the FCS and new results for a generalized diffusive wire.

Religious lobby groups: The pluralism of the Catholic community
Creators: name: O'Hara, Thomas John
Publisher: name: American University
Year: 2023

description: The diversity of the Catholic lobby in the federal policy arena is the nature of this study. This dissertation's central point is that the Catholic lobby in Washington, D.C., is not monolithic. Previous studies have concentrated only on the institutional lobby of the bishops and have equated that lobby with the total Catholic lobby. This study disputes that notion by documenting the existence of thirty other Catholic lobby groups in Washington. In-depth interviews were conducted with these groups which resulted in data that were used to test hypotheses derived from interest group literature. Responses to questions on group formation, maintenance, and strategy were quantified using dBase III Plus. The quantification of essentially qualitative material allowed for testing of hypotheses. Results show that there is indeed a pluralism within the Catholic lobby. Institutional Catholic groups differ from other Catholic groups in most areas of interest group behavior, confirming Salisbury's description of institutional group behavior. All groups offer forms of selective benefits to members, consistent with the Olsons' benefit theory. In addition, patrons, as described by Walker, are very much in evidence within this lobby. Finally, there are a variety of strategies employed by these groups in their lobbying efforts. The study contributes to both the literature of religion and politics, as well as the literature of interest group behavior. Both bodies of literature have failed, for the most part, to examine religious lobby groups. By examining the lobby of the largest religious denomination in the United States, valuable new data is provided.

Renormalons in integrated spectral function moments and $α_s$ extractions

description: Precise extractions of $α_s$ from $τ\to {\rm (hadrons)}+ν_τ$ and from $e^+e^-\to {\rm (hadrons)}$ below the charm threshold rely on finite energy sum rules (FESRs) where the experimental side is given by integrated spectral function moments. Here we study the renormalons that appear in the Borel transform of polynomial moments in the large-$β_0$ limit and in full QCD. In large-$β_0$, we establish a direct connection between the renormalons and the perturbative behaviour of moments often employed in the literature. The leading IR singularity is particularly prominent and is behind the fate of moments whose perturbative series are unstable, while those with good perturbative behaviour benefit from partial cancellations of renormalon singularities. The conclusions can be extended to QCD through a convenient scheme transformation to the $C$-scheme together with the use of a modified Borel transform which make the results particularly simple; the leading IR singularity becomes a simple pole, as in large-$β_0$. Finally, for the moments that display good perturbative behaviour, we discuss an optimized truncation based on renormalisation scheme (or scale) variation. Our results allow for a deeper understanding of the perturbative behaviour of integrated spectral function moments and provide theoretical support for low-$Q^2$ $α_s$ determinations.

Capacity Constraints and Destructive Competition in the Extraction of Non-Renewable Natural Resources

Year: 1981
Subjects: Financial Economics

description: The effects of two practical features associated with the extraction of a non-renewable natural resource on the behavior of a resource firm and industry are examined. These features are capacity and minimum efficient scale constraints. It is shown that these constraints can give rise to a phenomenon known as destructive competition. If destructive competition occurs, a perfect foresight equilibrium will not exist because the set of intertemporal shadow prices for the resource will not be sustainable by competitive behavior of firms. It is then shown that each firm's extraction path over time will be affected by these constraints and will have regions where the market price of the resource is constant. Possible time paths of momentary equilibria in a resource market are then derived when firms expectations about the resource price path are incorrect due to capacity constraints and destructive competition. Examples of destructive competition and its policy implications are also presented.

description: Spacecraft neutralisers are required as part of the ion propulsion system for accurate station keeping in fundamental physics missions. This paper describes the use of thin layers of insulating materials as coatings for the gated silicon field emitter array structure used in a spacecraft neutraliser. These thin coatings are postulated to reduce power consumption and reduce overheating. The power consumption and lifetime of aluminium nitride and amorphous hydrogenated diamond-like carbon coatings have been tested by current-voltage and endurance tests. Diamond-like carbon coatings were promising, performing better in endurance tests than uncoated samples, but further work is required to characterise the coating's physical properties and its effects on field emission. The thermal conductivity of the coating material had little effect on measured sample lifetimes. Aluminium nitride had reduced power consumption compared to diamond-like carbon coated and uncoated samples. A thin (~5 nm) layer of aluminium nitride was found to be optimal, meeting European Space Agency specifications for the neutraliser engineering model.

The Small Oil Producer in the World Economy A Marco Model

description: This paper models the macro-effects of exogenous oil and other shock on a small open economy (SOE) which is, itself, an oil producer. The model differs from existing literature in three major respects. First, the SOE has bot an oil sector and a manufacturing sector, where oil is used as an intermediate input. Second, the world economy in which the SOE is imbedded is explicitly modelled. It contains two additional nations: a large, dominantfirm- type oil monopolist, OPEC; and a large manufacturer, the rest-of-theworld (ROW), who uses imported oil as an intermediate input. Domestic and foreign manufactures are imperfect substitutes. Third, the SOE's authorities may, as in Canada, prevent world oil prices from being passed through to the domestic economy. Conventionally, the model is short-run while the world is characterized by flexible exchange rates, perfect financial capital mobility and rational expectations. The paper then analyzes the effects of various domestic and foreign shocks on the SOE's real GNP, consumer price index, and the composition of these two magnitudes. Of particular interest is the insulation properties, if any, of indexing domestic to world oil prices.

description: Using a prototype non-market-clearing model, this paper analyses the implications of simultaneous output, price and wage adjustment at finite rates. Firms use a Marshallian-type output adjustment which utilizes available information about notional magnitudes. With this adjustment structure, the Walrasian equilibrium is shown to be globally stable. This result is compared with other formulations of the dynamics: such as, the usual structure which results in a continuum of non-Walrasian equilibria (along a boundary between regimes); and the formulation which excludes the forces of motion on the regime boundaries.

Slice Stretching Effects for Maximal Slicing of a Schwarzschild Black Hole

Publisher: name: arXiv
Year: 2004
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: Slice stretching effects such as slice sucking and slice wrapping arise when foliating the extended Schwarzschild spacetime with maximal slices. For arbitrary spatial coordinates these effects can be quantified in the context of boundary conditions where the lapse arises as a linear combination of odd and even lapse. Favorable boundary conditions are then derived which make the overall slice stretching occur late in numerical simulations. Allowing the lapse to become negative, this requirement leads to lapse functions which approach at late times the odd lapse corresponding to the static Schwarzschild metric. Demanding in addition that a numerically favorable lapse remains non-negative, as result the average of odd and even lapse is obtained. At late times the lapse with zero gradient at the puncture arising for the puncture evolution is precisely of this form. Finally, analytic arguments are given on how slice stretching effects can be avoided. Here the excision technique and the working mechanism of the shift function are studied in detail.

description: It is known from both theory and experiments that introducing time delays into the communication network of mobile-agent swarms produces coherent rotational patterns. Often such spatio-temporal rotations can be bistable with other swarming patterns, such as milling and flocking. Yet, most known bifurcation results related to delay-coupled swarms rely on inaccurate mean-field techniques. As a consequence, the utility of applying macroscopic theory as a guide for predicting and controlling swarms of mobile robots has been limited. To overcome this limitation, we perform an exact stability analysis of two primary swarming patterns in a general model with time-delayed interactions. By correctly identifying the relevant spatio-temporal modes that determine stability in the presence of time delay, we are able to accurately predict bistability and unstable oscillations in large swarm simulations-- laying the groundwork for comparisons to robotics experiments.

description: We study the gauged sigma model and its mirror Landau-Ginsburg model corresponding to type IIA on the Fermat degree-24 hypersurface in WCP^4[1,1,2,8,12] (whose blow-up gives the smooth CY_3(3,243)) away from the orbifold singularities, and its orientifold by a freely-acting antiholomorphic involution. We derive the Picard-Fuchs equation obeyed by the period integral as defined in the work of Cecotti and Hori-Vafa, of the parent N=2 type IIA theory of Kachru and Vafa. We obtain the Meijer's basis of solutions to the equation in the large {\it and} small complex structure limits (on the mirror Landau-Ginsburg side) of the abovementioned Calabi-Yau, and make some remarks about the monodromy properties associated based on the work of Morrison, at the same and another MATHEMATICAlly interesting point. Based on a recently shown N=1 four-dimensional triality (hep-th/0212054) between Heterotic on the self-mirror Calabi-Yau CY_3(11,11), M theory on (CY_3(3,243) x S^1)/Z_2 and F-theory on an elliptically fibered CY_4 with the base given by CP^1 x Enriques surface, we first give a heuristic argument that there can be no superpotential generated in the orientifold of of CY_3(3,243), and then explicitly verify the same using mirror symmetry formulation of Hori-Vafa for the abovementioned hypersurface away from its orbifold singularities. We then discuss briefly the sigma model and the mirror Landau-Ginsburg model corresponding to the resolved Calabi-Yau as well.

description: The objective of this research was to develop a simple, sensitive, and useful method for the trapping and detection of environmental electrophiles using specific monoclonal antibodies (MAbs) in Enzyme-Linked Immunosorbent Assays (ELISAs). The MAbs were raised against thiol adducts of phenanthrene-9,10-oxide (PhO). A thiolated polymer on a solid support was used to trap PhO by covalent bonding. Ten picomole level of the PhO was detected with a direct ELISA assay. Some of the antibodies were inhibited in a competitive assay when different thiol compounds, including a purine riboside, were used to trap PhO in solution as a soluble competitor. Picomole and sub-picomole levels of PhO were detected in these assays and in a competitive assay using PhO, without thiolation, as the soluble competitor. No interference with the electrophile trapping or the ELISA assay by tap or distilled water was observed. Turbidity due to bacteria (about 107 million Salmonella per milliliter) and suspended clay particles (up to 2 mg/mL) also did not interfere with the assay procedures. pH values between 5 and 9 did not affect the assay. However, 0.088 mM of chlorine and 1.25 mM humic acid total organic carbon (TOC) did affect the assay. Because chirality is an important determinant of the toxicity of electrophilic metabolites, chiral specificities of the antibodies were determined. Antibody 9PC3 recognized thiol adducts of the K-region epoxides of benzo(a)pyrene (B(a)P), pyrene, benz(a)anthracene (BA), benzo(c)phenanthrene (B(c)Ph) and 1-azaphenanthrene (1-APh) at picomole and sub-picomole levels. Antibody 1PD2 recognized only the thiol adducts of BA and B(c)Ph. It did not recognize 1-APh-oxide thiol adducts despite the recognition of femtomole levels of PhO and its thiol adducts. The antibodies showed between 10- to 50-fold preference for the S,S isomers of the thiol adducts over the R,R isomers. While 9PC3 generally prefered S,S adducts, it also showed an unusual 10-fold preference for one R,R BA-oxide-glutathione adduct over its S,S stereoisomer and a 133-fold preference for an R,R isomer of 1-APh-oxide-glutathione over its S,S isomer. This information was used to propose a model for the binding sites of antibodies 9PC3 and 1PD2.

Strategy and interfirm organization: An empirical test

Year: 2023

description: The study investigates the relevance of the firm strategy concept to the explanation of oligopoly behavior in the producer-good process manufacturing industries through an analysis of evidence provided by the Federal Trade Commission's Line of Business database. This database permitted the econometric analysis of profitability at an unusually disaggregated level. Concentration in 1977 (the year characterized by the least amount of macroeconomic turbulence) has a significant positive impact on industry cooperation for industries with an above average level of strategic homogeneity. Concentration, however, has a significant negative impact in industries with below average strategic homogeneity. The novel findings of this study indicate that the strategic homogeneity measure can be used to identify, for producer-goods process manufacturing, those industries where the concentration-cooperation hypothesis is valid and those industries where this hypothesis is contradicted (and not simply not supported) by the evidence. The results also indicate that the strategic homogeneity measures developed for this study provide a better means of sorting than the previous measures (that were designed with reference to the late 1960s). This indicates that the measures developed in this study, besides being more replicable, have been able to capture the strategic changes that occurred in these industries over the early 1970s. The 1977 results, however, offer no support for the importance of strategy variables as explanatory variables in their own right. Moreover, model selection criteria suggest that mean squared error may be reduced by dropping the strategy variables from the model.

The main idea of this reconstruction is based on the monotonicity property of the Neumann-to-Dirichlet operator presented in a former article of the authors. Thus, we introduce the so-called standard as well as linearized monotonicity tests in order to detect and reconstruct inclusions. In addition, we compare these methods with each other and present several numerical test examples.

An evaluation of the ability of mandatory work programs to reduce welfare caseloads
Creators: name: Brasher, Charles Nielsen
Publisher: name: American University
Year: 2023

description: This research examines the relationship between mandatory work programs and welfare caseloads. The purpose is to determine if workfare reduces welfare caseloads and if so why workfare is effective and in what environments it is most effective. The focus of the study is the Community Work Experience Program (CWEP) and the Aid for Families With Dependent Children (AFDC) population. CWEP, authorized in 1981, gave the states permission to require AFDC recipients to "work off" their welfare grant. Two different populations are examined: an interstate model that compares CWEP-states with non-CWEP states and an intrastate model that compares CWEP counties and non-CWEP counties in Ohio. Quarterly data from 1981 to 1986 were collected for each state and county. Multiple regression is used to test the association between CWEP and AFDC caseloads, controlling for important political, programmatic, demographic and economic variables. AFDC applications and terminations are analyzed to examine if CWEP's effectiveness is caused by deterrence or work experience. A reduction in applications suggests deterrence. A long-term increase in termination suggests work experience. A series of slope dummy variables are used to determine the impact of political, programmatic and demographic variables on CWEP's effectiveness. The research showed that CWEP was associated with a reduction in AFDC caseloads. The most impressive results were in the Ohio study, where average over the implementation period, AFDC caseloads were found to decrease by 3.5 percent and AFDC-U caseloads by 16.7 percent. The results were much higher by the third year of implementation, suggesting that the long-term impact of CWEP is much higher than the average impact. The national findings showed a 12.4 decrease in AFDC-U caseloads but no change in AFDC caseloads. The Ohio findings also indicated that work experience was the primary reason for the program's success. There were no statistically significant findings indicating that CWEP was a deterrent to welfare. The national findings were inconclusive. In both the Ohio and national studies, CWEP was more effective in Republican and conservative jurisdictions. Programmatic and demographic variables were also associated with CWEP's success, but the political variables had the greatest impact.

description: This research examines the relationship between mandatory work programs and welfare caseloads. The purpose is to determine if workfare reduces welfare caseloads and if so why workfare is effective and in what environments it is most effective. The focus of the study is the Community Work Experience Program (CWEP) and the Aid for Families With Dependent Children (AFDC) population. CWEP, authorized in 1981, gave the states permission to require AFDC recipients to "work off" their welfare grant. Two different populations are examined: an interstate model that compares CWEP-states with non-CWEP states and an intrastate model that compares CWEP counties and non-CWEP counties in Ohio. Quarterly data from 1981 to 1986 were collected for each state and county. Multiple regression is used to test the association between CWEP and AFDC caseloads, controlling for important political, programmatic, demographic and economic variables. AFDC applications and terminations are analyzed to examine if CWEP's effectiveness is caused by deterrence or work experience. A reduction in applications suggests deterrence. A long-term increase in termination suggests work experience. A series of slope dummy variables are used to determine the impact of political, programmatic and demographic variables on CWEP's effectiveness. The research showed that CWEP was associated with a reduction in AFDC caseloads. The most impressive results were in the Ohio study, where average over the implementation period, AFDC caseloads were found to decrease by 3.5 percent and AFDC-U caseloads by 16.7 percent. The results were much higher by the third year of implementation, suggesting that the long-term impact of CWEP is much higher than the average impact. The national findings showed a 12.4 decrease in AFDC-U caseloads but no change in AFDC caseloads. The Ohio findings also indicated that work experience was the primary reason for the program's success. There were no statistically significant findings indicating that CWEP was a deterrent to welfare. The national findings were inconclusive. In both the Ohio and national studies, CWEP was more effective in Republican and conservative jurisdictions. Programmatic and demographic variables were also associated with CWEP's success, but the political variables had the greatest impact.

description: Anisotropic dipole-dipole interaction often plays a key role in biological, soft, and complex matter. For it to induce non-trivial order in the system, there must be additional repulsive interactions or external potentials involved that partially or completely fix the positions of the dipoles. These positions can often be represented as an underlying lattice on which dipole interaction induces orientational ordering of the particles. On lattices in the Euclidean plane, dipoles have been found to assume different ground state configurations depending on the lattice type, with a global ordering in the form of a macrovortex being observed in many cases. A similar macrovortex configuration of dipoles has recently been shown to be the sole ground state for dipoles positioned on spherical lattices based on solutions of the Thomson problem. At the same time, no symmetric configurations have been observed, even though the positional order of Thomson lattices exhibits a high degree of symmetry. Here, we show that a different choice of spherical lattices based on Caspar-Klug construction leads to ground states of dipoles with various degrees of symmetry, including the icosahedral symmetry of the underlying lattice. We analyze the stability of the highly symmetric metastable states, their symmetry breaking into subsymmetries of the icosahedral symmetry group, and present a phase diagram of symmetries with respect to lattice parameters. The observed relationship between positional order and dipole-induced symmetry breaking hints at ways of fine-tuning the structure of spherical assemblies and their design.

A comparison of signs of nutritional stress in prehistoric populations of the Potomac Piedmont and Coastal Plain

description: The transition from less intensive to more intensive agriculture was examined in skeletal populations excavated from sites in the Potomac Piedmont and Coastal Plain. Sites in the Piedmont represent small villages located on naturally fertile siltloam where agriculture was practiced along with hunting and gathering. The same pattern is true of the Coastal Plain except that the villages were larger, more centralized, crowded and palisaded. There is evidence that the transition from hunting and gathering to sedentism and agriculture was accompanied by a deterioration in health status. This study attempted to determine whether or not further signs of stress were apparent as agriculture intensified. The skeletal material was examined for differences in stature and robusticity. Developmental disturbances as evidenced by enamel hypoplasias and Harris lines were also observed. Dental pathology in the form of carious lesions, periodontal disease, abscesses and antemortem tooth loss was also recorded, as were signs of infection (periosteal inflammation) and iron deficiency anemia (cribra orbitalia and porotic hyperostosis). The results show that, while not all differences were significant, the Coastal Plain population fared somewhat better than did the Piedmont group. Significant differences were seen in the incidences of dental caries and antemortem tooth loss. More people in the Piedmont exhibited these lesions, although the average number of lesions per person was not significantly different between the two populations. There was a significantly increased incidence of enamel hypoplasia among the Piedmont group and the number of hypoplastic lesions per person was significant at the 0.1 level. Since this is a developmental disturbance, it was suggested that the oysters which are available in increased proportions in the Coastal Plain might have supplied enough calcium to individuals as they matured so that hypoplasia was not as prevalent. Caries and antemortem tooth loss in the Piedmont, usually a result of high carbohydrate diets, may be an artifact of the extremely small Piedmont sample. In this study, there was no sign of increased nutritional stress as the populations changed from less intensive to more intensive agriculture. Indeed, it appears that a natural environment resource may offset the deleterious effects of a high carbohydrate diet.

description: We derive model independent lower bounds on the CKM parameters (1-rhobar) and etabar as functions of the mixing-induced CP asymmetry S in B-> pi+ pi- and sin(2 beta) from B->psi K_S. The bounds do not depend on specific results of theoretical calculations for the penguin contribution to B-> pi+ pi-. They require only the very conservative condition that a hadronic phase, which vanishes in the heavy-quark limit, does not exceed 90 degrees in magnitude. The bounds are effective if -sin(2 beta) < S < 1. Dynamical calculations indicate that the limits on rhobar and etabar are close to their actual values.
