description: It was recently claimed that several galaxy clusters containing radial and tangential gravitational arcs and having a measured velocity-dispersion profile for the brightest cluster galaxy had to have central density profiles considerably flatter than those found in CDM cluster simulations. Using a simple analytic mass model, we confirm this result_for axially symmetric_ mass distributions, but show that steep density profiles are well in agreement with the cluster requiring the flattest axially symmetric profile once even small deviations from axial symmetry are introduced.

title: Multinationality In The Oil And Gas Industry
Creators: name: Dale, Colin
Publisher: name: The Open University
Year: 2010

description: This Masters Research offers uses new data analysis techniques to address intra-firm data segmented by business and geography for an industry specific set of firms. It tests whether oil and gas firms are global in their operations and hence sales to/revenues from consumers. Rugman and Verbeke (2004) suggest firms demonstrate a preference for local over global strategies when investing abroad and Rugman (2005) augments this theoretical position with industry level analysis and firm level case studies. They make a quantitative analysis of geographic revenue dispersion for 500 firms and find results supporting regional theories. The analysis takes nine years of data as a longitudinal panel data set that offers, for the first time, trend data analysis into the debate around global versus local strategies. Corporate finance theory informs selection of performance proxies that recover 'missing' observations but high regional focus in revenues is again found in the numerical majority of firms. 67% of weighted total firm revenue for FY2008 is intra-regional, as suggested by Rugman (2005). This extended data now shows new global and bi-regional cases, a variation in comparative global focus across the value chain for the largest oil and gas firms and movement away from home country and region. Modelling using this new data shows no support for the existence of multiple-order regression equations linking regionalism to firm performance. No correlation is found between oil price, performance and multi-nationality for these firms but there is an inverse correlation between multi-nationality and revenue. This suggests that extant theories of decreased performance against increased scale are not evidenced in this specific industry and hence suggests that both size and history do matter.

description: Experimental and numerical investigation of single-beam and pump-probe interaction with a resonantly absorbing dense extended medium under strong and weak field-matter coupling is presented. Significant probe beam amplification and conical emission were observed. Under relatively weak pumping and high medium density, when the condition of strong coupling between field and resonant matter is fulfilled, the probe amplification spectrum has a form of spectral doublet. Stronger pumping leads to the appearance of a single peak of the probe beam amplification at the transition frequency. The greater probe intensity results in an asymmetrical transmission spectrum with amplification at the blue wing of the absorption line and attenuation at the red one. Under high medium density, a broad band of amplification appears. Theoretical model is based on the solution of the Maxwell-Bloch equations for a two-level system. Different types of probe transmission spectra obtained are attributed to complex dynamics of a coherent medium response to broadband polychromatic radiation of a multimode dye laser.

Andreev billiards

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)
subject: FOS: Physical sciences

description: This is a review of recent advances in our understanding of how Andreev reflection at a superconductor modifies the excitation spectrum of a quantum dot. The emphasis is on two-dimensional impurity-free structures in which the classical dynamics is chaotic. Such Andreev billiards differ in a fundamental way from their non-superconducting counterparts. Most notably, the difference between chaotic and integrable classical dynamics shows up already in the level density, instead of only in the level--level correlations. A chaotic billiard has a gap in the spectrum around the Fermi energy, while integrable billiards have a linearly vanishing density of states. The excitation gap E_gap corresponds to a time scale h/E_gap which is classical (h-independent, equal to the mean time t_dwell between Andreev reflections) if t_dwell is sufficiently large. There is a competing quantum time scale, the Ehrenfest time t_E, which depends logarithmically on h. Two phenomenological theories provide a consistent description of the t_E-dependence of the gap, given qualitatively by E_gap min(h/t_dwell,h/t_E). The analytical predictions have been tested by computer simulations but not yet experimentally.

description: This study seeks (1) to identify and evaluate an interpretation of tribal arts and crafts; (2) to demonstrate tribal strategies in the production of arts and crafts; to use these data as a means for comparison of such strategies; (3) to obtain and manage an anthropological understanding of native arts and crafts and of projects designed to promote traditional native arts and crafts. The research project investigates the problem inherent in (1) comparisons of material objects (primarily art objects) from similar cultures and from differing cultures and (2) changes through time in relationships between objects and their producers. World-wide sampling was used to establish correlations between levels of sociocultural integration and changes in arts and crafts strategies. Sampling cultures throughout the United States, the project explores characteristics of contemporary North American Indian arts and crafts. The project establishes (1) a general basis of tribe vs. state for the interpretation of arts and crafts; (2) defines the dimensions of tribal arts and crafts; (3) demonstrates the development of tribal arts and crafts after modernization; and (4) predicts trends for the future, with specific recommendations for planning.
RADIATION-INDUCED PRODUCTS OF PEPTIDES AND THEIR ENZYMATIC DIGESTIBILITY
Creators: name: Gajewski, Ewa
Publisher: name: American University
Year: 2023

description: Chemical characterization of radiation-induced products of peptides and proteins is essential for understanding the effect of ionizing radiation on peptides and proteins. Furthermore, peptides containing radiation-altered amino acid residues might not be completely digestible by proteolytic enzymes. In this work, small homopeptides of Ala, Phe and Met were chosen as model peptides. Lysozyme was used to investigate the effect of ionizing radiation on a small protein. All peptides and lysozyme were irradiated in diluted, oxygen free, N(,2)O-saturated aqueous solutions, using a ('60)Co-(gamma)-source. HPLC, capillary GC and GC-MS were applied to isolate and characterize the radiation-induced products. The enzymatic digestibility of the products was investigated using aminopeptidase M, leucine aminopeptidase, carboxypeptidase A and carboxypeptidase Y. For L-Ala peptides, radiation-induced D-Ala was observed. Biphenyl type dimers and products containing o-, m- and p- Tyr were formed in irradiated solutions of L-Phe peptides. 2-aminobutanoic acid, methionine sulfoxide, 2-amino-4-(methyldithio)butanoic acid, 4,4'-thiobis(2-aminobutanoic acid) and homocystine were identified as radiation-induced products of Met peptides after HCl-hydrolysis. Radiation-induced D-Met was also observed. For irradiated lysozyme, allo-Thr, 2-aminobutanoic acid, o- and m-Tyr and 2- and 3-hydroxytyrosines were identified after HCl-hydrolysis. Yields of radiation-induced products in all cases were also determined by GC. Enzymatic hydrolysis of irradiated Ala, Phe and Met homopeptides demonstrated the different actions of four enzymes used on radiation-induced products. Peptide bonds of radiation-induced dimers of di-Ala were resistant to enzymatic hydrolysis whereas those of radiation-induced dimers of Phe-peptides were readily cleaved by the enzymes except for carboxypeptidase Y. For Met-peptides, peptide bonds of radiation-induced products were cleaved by all four exopeptidases in most cases. In conclusion, it was found that irradiation of peptides examined in this work leads to racemization and alteration of amino acid residues and crosslinks between the peptide chains. In addition, it was established that exopeptidases act differently on radiation-induced dimers of peptides composed of aliphatic, aromatic and sulfur-containing amino acids.

description: We consider the Cauchy problem for the focusing nonlinear Schrödinger equation with initial data approaching two different plane waves $A_j\mathrm{e}^{\mathrm{i}ϕ_j}\mathrm{e}^{-2\mathrm{i}B_jx}$, $j=1,2$ as $x\to\pm\infty$. Using Riemann-Hilbert techniques and Deift-Zhou steepest descent arguments, we study the long-time asymptotics of the solution. We detect that each of the cases $B_1B_2$, and $B_1=B_2$ deserves a separate analysis. Focusing mainly on the first case, the so-called shock case, we show that there is a wide range of possible asymptotic scenarios. We also propose a method for rigorously establishing the existence of certain higher-genus asymptotic sectors.

description: In order to fabricate precise atomic-scale devices in silicon using a combination of scanning tunnelling microscopy (STM) and molecular beam epitaxy it is necessary to minimize the segregation/diffusion of dopant atoms during silicon encapsulation. We characterize the surface segregation/diffusion of phosphorus atoms from a $δ$-doped layer in silicon after encapsulation at 250$^{\circ}$C and room temperature using secondary ion mass spectrometry (SIMS), Auger electron spectroscopy (AES), and STM. We show that the surface phosphorus density can be reduced to a few percent of the initial $δ$-doped density if the phosphorus atoms are encapsulated with 5 or 10 monolayers of epitaxial silicon at room temperature. We highlight the limitations of SIMS and AES to determine phosphorus segregation at the atomic-scale and the advantage of using STM directly.

description: We present the variability study of the lowest-luminosity Seyfert 1 galaxy NGC 4395 based on the photometric monitoring campaigns in 2017 and 2018. Using 22 ground-based and space telescopes, we monitored NGC 4395 with a $\sim$5 minute cadence during a period of 10 days and obtained light curves in the UV, V, J, H, and K/Ks bands as well as the H$α$ narrow-band. The RMS variability is $\sim$0.13 mag on \emph{Swift}-UVM2 and V filter light curves, decreasing down to $\sim$0.01 mag on K filter. After correcting for continuum contribution to the H$α$ narrow-band, we measured the time lag of the H$α$ emission line with respect to the V-band continuum as ${55}^{+27}_{-31}$ to ${122}^{+33}_{-67}$ min. in 2017 and ${49}^{+15}_{-14}$ to ${83}^{+13}_{-14}$ min. in 2018, depending on the assumption on the continuum variability amplitude in the H$α$ narrow-band. We obtained no reliable measurements for the continuum-to-continuum lag between UV and V bands and among near-IR bands, due to the large flux uncertainty of UV observations and the limited time baseline. We determined the AGN monochromatic luminosity at 5100Å $λL_λ= \left(5.75\pm0.40\right)\times 10^{39}\,\mathrm{erg\,s^{-1}}$, after subtracting the contribution of the nuclear star cluster. While the optical luminosity of NGC 4395 is two orders of magnitude lower than that of other reverberation-mapped AGNs, NGC 4395 follows the size-luminosity relation, albeit with an offset of 0.48 dex ($\geq$2.5$σ$) from the previous best-fit relation of Bentz et al. (2013).

description: Observations of molecular clouds show the existence of starless, dense cores, threaded by magnetic fields. Observed line widths indicate these dense condensates to be embedded in a supersonically turbulent environment. Under these conditions, the generation of magnetic waves is inevitable. In this paper, we study the structure and support of a 1D plane-parallel, self-gravitating slab, as a monochromatic, circularly polarized Alfven wave is injected in its central plane. Dimensional analysis shows that the solution must depend on three dimensionless parameters. To study the nonlinear, turbulent evolution of such a slab, we use 1D high resolution numerical simulations. For a parameter range inspired by molecular cloud observations, we find the following. 1) A single source of energy injection is sufficient to force persistent supersonic turbulence over several hydrostatic scale heights. 2) The time averaged spatial extension of the slab is comparable to the extension of the stationary, analytical WKB solution. Deviations, as well as the density substructure of the slab, depend on the wave-length of the injected wave. 3) Energy losses are dominated by loss of Poynting-flux and increase with increasing plasma beta. 4) Good spatial resolution is mandatory, making similar simulations in 3D currently prohibitively expensive.

A STUDY AND ANALYSIS OF THE VARIABLES DETERMINING THE RETENTION BEHAVIOR OF VOLUNTEERS
Creators: name: Rodriguez, Mary Chesley
Publisher: name: American University
Year: 2023

description: The purpose of this dissertation is to identify those determinants of volunteer behavior which could be included in a meaningful process of planning for volunteer retention. By the comparison of the motivation for paid and unpaid for work, it was demonstrated that volunteer activity could be brought within the framework of exchange theory. The volunteers of a small, non-profit organization in the Washington Metropolitan Area were used as the data base. These subjects had tutored under the auspices of this agency during the years 1972-1978. The examination and analysis of the socio-economic characteristics of this volunteer population revealed that these variables could not be regarded as valid indicators of participation in the volunteer enterprise nor as factors determining the length of service. It was found that this volunteer population was in a state of transition and that it was becoming one more representative of the overall American population. The administration of a research instrument, developed for the purpose, to a random sample of the population studied disclosed certain themes permeating the responses of the subjects. These were conceptualized under the rubric of the four wishes of W. I. Thomas for security, new experience, response, and recognition. Five components of the satisfaction of these wishes were quantified for the responses. From these, an index was developed which was projected against the longevity of service. This resulted in the identification of the fulfillment of these needs/wishes as potent factors in the retention of volunteers. The respondents' perceptions of such wish/need fulfillment were consistently positively correlated with their length of service. Some tangible suggestions are offered for the modification of existing policy in the relationships between agencies and the volunteers affiliated with them. These include greater volunteer acceptance by staff, equality with staff, recognition, and provision for interaction among volunteers.

description: The first moment the chirality-odd twist-3 parton distribution $e(x)$ is related to the pion-nucleon $σ$-term which is important for phenomenology. However, the possible existence of a singular contribution proportional to $δ(x)$ in the distribution prevents from the determination of the $σ$-term with $e(x)$ from experiment. There are two approaches to show the existence. The first one is based on an operator identity. The second one is based on a perturbative calculation of a single quark state with finite quark mass. We show that all contributions proportional to $δ(x)$ in the first approach are in fact cancelled. To the second approach we find that $e(x)$ of a multi-parton state with a massless quark has no contribution with $δ(x)$. Considering that a proton is essentially a multi-parton state, the effect of the contribution with $δ(x)$ is expected to be suppressed by light quark masses with arguments from perturbation theory. A detailed discussion about the difference between cut- and uncut diagrams of $e(x)$ is provided.

description: The purpose of this dissertation is to identify those determinants of volunteer behavior which could be included in a meaningful process of planning for volunteer retention. By the comparison of the motivation for paid and unpaid for work, it was demonstrated that volunteer activity could be brought within the framework of exchange theory. The volunteers of a small, non-profit organization in the Washington Metropolitan Area were used as the data base. These subjects had tutored under the auspices of this agency during the years 1972-1978. The examination and analysis of the socio-economic characteristics of this volunteer population revealed that these variables could not be regarded as valid indicators of participation in the volunteer enterprise nor as factors determining the length of service. It was found that this volunteer population was in a state of transition and that it was becoming one more representative of the overall American population. The administration of a research instrument, developed for the purpose, to a random sample of the population studied disclosed certain themes permeating the responses of the subjects. These were conceptualized under the rubric of the four wishes of W. I. Thomas for security, new experience, response, and recognition. Five components of the satisfaction of these wishes were quantified for the responses. From these, an index was developed which was projected against the longevity of service. This resulted in the identification of the fulfillment of these needs/wishes as potent factors in the retention of volunteers. The respondents' perceptions of such wish/need fulfillment were consistently positively correlated with their length of service. Some tangible suggestions are offered for the modification of existing policy in the relationships between agencies and the volunteers affiliated with them. These include greater volunteer acceptance by staff, equality with staff, recognition, and provision for interaction among volunteers.
A Test of CP Symmetry in Positronium

Year: 2004
Subjects: subject: High Energy Physics - Experiment (hep-ex)

description: The aim of this CP symmetry test in positronium is to measure the CP violation amplitude parameter \ccp. This is derived from the measurement of the asymmetry in an angular distribution of the photons from the decay of the ortho-positronium in a magnetic field. The Standard Model prediction for \ccp\ is a value of the order of $10^{-9}$. Thus the observation of a larger \ccp\ value would be signal of physics beyond the Standard Model. A previous measurement has found \ccp consistent with zero, with an uncertainty of $\sim 10^{-2}$. We have investigated the possibility of using the existing ETHZ-INRM-IN2P3 BGO crystal detector, set-up for positronium physics studies, to improve the sensitivity on the \ccp measurement. Preliminary calculations indicate that, using such an apparatus, with some modification, in a magnetic field of 4 kGauss, \ccp could be measured with an uncertainty in the range between $\sim 10^{-4}$ and $\sim 10^{-3}$, depending mainly on the uncertainty in the asymmetry measurement and the angular resolution of the photon detectors. If \ccp is less than $\sim 10^{-4}$, the experimental technique outlined here appears to be inadequate to observe a CP violating effect and new techniques or different observables must be exploited for better sensitivity.

THE USE OF THE CONFLICT CYCLE MODEL AND THE TWELVE TECHNIQUES FOR THE CLASSROOM MANAGEMENT OF SURFACE BEHAVIOR BY RESIDENTIAL CHILD CARE WORKERS TO INCREASE COMPETENCE IN THE BEHAVIOR MANAGEMENT OF AGGRESSIVE CHILDREN
Creators: name: Powell, Jr., Norman William
Publisher: name: American University

description: The acting-out behavior of the aggressive child has long presented many problems for teachers, child care workers, parents, and other members of society. Traditionally, little priority has focused on enabling teachers and child care workers to develop expertise in working with aggressive children. In recent years, several important concepts have emerged from the field of special education. This study proposed to determine whether the Conflict Cycle Model and the Twelve Techniques for the Classroom Management of Surface Behavior could be used effectively by residential child care workers to increase their competence in managing the behavior of aggressive children. Forty residential child care workers were randomly assigned to experimental and control groups. A specialized six-week inservice training program served as the independent treatment variable. Five hypotheses were tested. Namely, there will be no significant difference between the pre and post-test mean scores achieved on the: (1) Aggressive Behavior Frequency Inventory by the children of the workers in the experimental and control groups. (2) Behavior Management Competency Inventory #1 by workers in the experimental and control groups. (3) Behavior Management Competency Inventory #2 by workers in the experimental and control groups. (4) Child Care Worker Evaluation Forms by the workers in the experimental and control groups. (5) Self-Ratings of the workers in the experimental and control groups. No statistical differences were found on three of them: reducing child aggressive behavior, identifying elements of the Conflict Cycle, and supervisors' ratings. Significant differences were found in the area of the use of the Twelve Techniques and Self-Ratings by the workers. While the general hypothesis was not accepted, partial support of the inservice training model was established. The lack of statistical significance on the three study instruments could be explained by the limitations on the design and level of sophistication of the instruments. The development of reliable instruments and the need for more research in this area were recommended. Even with limitations, this study was the first attempt to provide child care workers with a systematic model for working with aggressive children. It was also recommended that behavior management training be developed for those who work with populations of children such as the blind, deaf, retarded, and multiple handicapped.

description: Increased pollution leads to a constant decrease of drinking water quality worldwide. Due to safety concerns, unpleasant taste and odour only about 3% of the population in South Korea is drinking untreated tap water. The present study uses choice experiments and cost-benefit analysis to investigate the feasibility of installing advanced water treatments in Cheongju waterworks in South Korea. The waterworks is situated in the middle of the country and is providing more than half a million people with drinking water. The study shows that the lower bound of the median WTP for installing a new advanced water treatment system is about $ 2 US/month, which is similar to the average expenditures for bottled water per household in South Korea. Scenarios under which the instalment of the advanced water treatments is feasible are discussed together with environmental solutions in the long-run.

description: Given a sequence of distinct positive integers $w_0 , w_1, w_2, \ldots$ and any positive integer $n$, we define the discriminator function $\mathcal{D}_{\bf w}(n)$ to be the smallest positive integer $m$ such that $w_0,\ldots, w_{n-1}$ are pairwise incongruent modulo $m$. In this paper, we classify all binary recurrent sequences $\{w_n\}_{n\geq 0}$ consisting of different integer terms such that $\mathcal{D}_{\bf w}(2^e)=2^e$ for every $e\geq 1.$ For all of these sequences it is expected that one can actually give a fairly simple description of $\mathcal{D}_{\bf w}(n)$ for every $n\ge 1.$ For two infinite families of such sequences this has been done already in 2019 by Faye, Luca and Moree, respectively Ciolan and Moree.

description: Enhancing agricultural productivity through the adoption of proven technologies presents a credible pathway to economic development and poverty reduction. The adoption of improved chickpea varieties in Ethiopia has the potential to contribute not only to food security but also to economic development as well as poverty reduction among the poor. We analyze the impacts of improved chickpea adoption on smallholder production and commercialization employing a triple hurdle (TH) model on a panel data of three rounds (2008, 2010, 2014), drawn from 614 households in potential chickpea areas in Ethiopia. The correlated random effect model coupled with the control function approach for non-linear panel models was employed to address heterogeneity and endogeneity. The adoption of improved chickpea varieties shows a significant positive effect on the commercialization of chickpea. This study therefore affirms the importance of improved chickpea varieties for commercialization and additionally provides support for policies targeting poverty alleviation in rural areas through targeting more novel farm technologies, improving extension services and increasing access to land especially by the young.
