Spatial data analysis of artifacts redeposited by coastal erosion: A case study of McFaddin Beach, Texas
Creators: name: Stright, Melanie Jean
Publisher: name: American University
Year: 2023

description: This study was undertaken to test the proposition that significant archaeological information can be extracted from a secondary deposit of artifacts found along a rapidly eroding coastline. The study area is McFaddin Beach, a 32-kilometer-long stretch of shoreline along the southeast coast of Texas. The artifacts included in the study were collected over a period of 26 years by five local collectors who kept detailed maps and records of each artifact find. The diagnostic artifacts in the study collection represent all cultural periods from Paleoindian to Historic. The method of analysis used a Geographic Information System, ARC/INFO, to synthesize information on the paleogeography of the coastal area where the lag deposit of artifacts was found and to conduct spatial analysis of the individual artifacts and their attributes. The results of the study indicate that even though the primary archaeological context of the artifacts has been destroyed, by reconstructing the larger paleogeographic context of the eroded sites and studying the attributes and spatial distribution of the artifacts in the lag deposit, some important archaeological conclusions can be drawn. These conclusions include information on how the prehistoric human populations of the McFaddin Beach area shifted through time and why, the general activities and the lithic procurement strategies of these populations, and the possible locations of the original archaeological sites from which the artifacts were eroded.

description: Given its relative proximity (~430 pc), compact size (< 20'), young age (~ 0.5 Myr) and rich number of young stellar objects, the Serpens-South star forming region is a promising site for studying young sub-stellar objects, yet the low-mass members of this region remain largely undiscovered. In this paper we report on a deep photometric survey using a custom 1.45 um filter (W-band), as well as standard J and H near-IR filters, in order to identify candidate low-mass young brown-dwarfs in the Serpens-South region. We constructed a reddening-insensitive index (Q) by combining J, H and W-band photometry for survey objects, in order to identify candidate low-mass members of Serpens based on the strength of the water absorption feature at 1.45 um in the atmospheres of mid-M and later objects. We then conducted spectroscopic follow up to confirm youth and spectral type for our candidates. This is the first survey to identify the very low-mass and coolest members of Serpens-South. We identify 4 low-mass candidate Serpens members, which all display IR excess emission, indicating the likely presence of circumstellar disks around them. One of the four candidate low-mass members in our list, SERP182918-020245, exhibits Pa_beta and Br_gamma emission features, confirming its youth and ongoing magnetospheric accretion. Our new candidate members have spectral types >M4 and are the coolest and lowest mass candidate members yet identified in Serpens-South.

description: Objectives: This project is part of a larger series in which we aim to assess or create filters for health disparities. Our objective was to design and validate a search filter for PubMed MEDLINE to retrieve literature pertinent to immigrant health disparities. Methods: We solicited expert opinion to address ambiguities in existing definitions of health disparities and immigrant status. Expert feedback guided the creation of inclusion and exclusion criteria. We performed a generic topic search in PubMed and screened the results using the inclusion/exclusion criteria to identify records for the development set. Frequency analysis and hand-searching of the development set were used to generate terms for an immigrant health disparities filter. We hand searched relevant journals indexed in PubMed to establish the validation set of articles (the gold standard). This validation set was used to test the sensitivity, specificity, precision, and accuracy of the immigrant health disparities filter.
Supplementary information on statistical procedures from Anthropogenic noise impairs foraging for cryptic prey via cross-sensory interference

description: Anthropogenic noise levels are globally rising with profound impacts on ecosystems and the species that live in them. Masking or distraction by noise can interfere with relevant sounds and thereby impact ecological interactions between individuals of the same or different species. Predator–prey dynamics are particularly likely to be influenced by rising noise levels, with important population- and community-level consequences, as species may differentially adapt to noise disturbance. Acoustic noise can, however, also impair the use of visual information by animals through the process of cross-sensory interference, possibly impacting species interactions that have so far been largely ignored by noise impact studies. Here, we assessed how noise affected the performance of great tit (Parus major) foraging on cryptic prey. Birds trained individually to search for paper moths differing in the level of camouflage with the test background were tested in the presence and absence of noise. We found that noise significantly increased approach and attack latencies, but that the effect depended on the level of crypsis. Noise increased latencies for cryptic prey targets, but not for conspicuous and colour-matched prey targets. Our results show that noise can interfere with the processing of visual information, particularly in difficult tasks such as separating objects from a similar looking background. These results have important ecological and evolutionary implications as they demonstrate how globally rising anthropogenic noise levels can influence the arms race between predators and prey across sensory domains.

An analysis of kinesthetic learners' responses: Teaching mathematics through dance
Creators: name: Westreich, Galeet Benzion
Publisher: name: American University
Year: 2023

description: This study was designed to look at the learning process of students with kinesthetic learning as their dominant learning style. To achieve this, kinesthetic learners (KLs) were observed as they studied geometry concepts in a mathematics classroom. The need for understanding KLs' learning process in the context of learning mathematics arises from existing studies showing that: (a) KLs are able to demonstrate increased academic achievement when instruction incorporates dance activities; and (b) when dance activities are riot incorporated into KLs' instruction, their performance on mathematics tests drops below grade level average. The need for this study is also supported by the constructivist theory of knowledge. This perspective advocates that mathematical-thinking develops through exploration that is tightly connected with real and meaningful experiences. That is, learners need to explore mathematics in situations that make sense to them. This researcher's position is that KLs currently fail mathematics tests because they are not given the opportunity to explore mathematics through situations that most make sense to them---kinesthetic situations, i.e., dance. Instead, most mathematics teaching (at the elementary level) requires learners to have strong and proficient auditory, visual and tactile processes. These learning modes, however, are not compatible with KLs' learning strengths. Because KLs' dominant learning mode is kinesthetic sense, teaching that relies on other modes prevents them from achieving their highest academic potential. A qualitative case study was designed, conducted and analyzed to answer the study's question. This study produced the following: (1) A clear definition of KLs' characteristic behavioral responses in the academic environment. (2) A kinesthetic-teaching strategy designed to assist teachers to teach academic curriculum, specifically mathematics, to kinesthetic learners by using dance activities. (3) An explanation of the ways in which teaching kinesthetically assists KLs to achieve their highest academic potential, and improve their auditory, visual and communication processing.

description: An experimental scheme is proposed to test Bell's inequality by using superconducting nanocircuits. In this scheme, quantum entanglement of a pair of charge qubits separated in a sufficient long distance may be created by cavity quantum electrodynamic techniques; the population of qubits is experimentally measurable by dc currents through the probe junctions, and one measured outcome may be recorded for every experiment. Therefore, both locality and detection efficiency loopholes should be closed in the same experiment. We also propose a useful method to measure the amount of entanglement based on the concurrence between Josephson qubits. The measurable variables for Bell's inequality as well as the entanglement are expressed in terms of a useful phase-space Q function.

description: We propose the formulation of a dihadron fragmentation function in terms of parton matrix elements. Under the collinear factorization approximation and facilitated by the cut-vertex technique, the two hadron inclusive cross section at leading order (LO) in e+ e- annihilation is shown to factorize into a short distance parton cross section and the long distance dihadron fragmentation function. We also derive the DGLAP evolution equation of this function at leading log. The evolution equation for the non-singlet quark fragmentation function is solved numerically with a simple ansatz for the initial condition and results are presented for cases of physical interest.

Blending and obscuration in weak lensing magnification

description: We test the impact of some systematic errors in weak lensing magnification measurements with the COSMOS 30-band photo-$z$ Survey flux limited to $I_{auto}<25.0$ using correlations of both source galaxy counts and magnitudes. Systematic obscuration effects are measured by comparing counts and magnification correlations. We use the ACS-HST catalogs to identify potential blending objects (close pairs) and perform the magnification analyses with and without blended objects. We find that blending effects start to be important ($\sim$ 0.04~mag obscuration) at angular scales smaller than 0.1 arcmin. Extinction and other systematic obscuration effects can be as large as 0.10~mag (U-band) but are typically smaller than 0.02~mag depending on the band. After applying these corrections, we measure a $3.9σ$ magnification signal that is consistent for both counts and magnitudes. The corresponding projected mass profiles of galaxies at redshift $z \simeq 0.6$ ($M_I \simeq -21$) is $Σ= 25\pm 6 M_{sun}h^3/pc^2$ at 0.1 Mpc/h, consistent with NFW type profile with $M_{200} \simeq 2 \times 10^{12} M_{sun} h/pc^2$. Tangential shear and flux-size magnification over the same lenses show similar mass profiles. We conclude that magnification from counts and fluxes using photometric redshifts has the potential to provide complementary weak lensing information in future wide field surveys once we carefully take into account systematic effects, such as obscuration and blending.

description: We consider the minimal free resolutions of Stanley-Reisner rings associated to linear codes and give an intrinsic characterization of linear codes having a pure resolution. We use this characterization to quickly deduce the minimal free resolutions of Stanley-Reisner rings associated to MDS codes as well as constant weight codes. We also deduce that the minimal free resolutions of Stanley-Reisner rings of first order Reed-Muller codes are pure, and explicitly describe the Betti numbers. Further, we show that in the case of higher order Reed-Muller codes, the minimal free resolutions are almost always not pure. The nature of the minimal free resolution of Stanley-Reisner rings corresponding to several classes of two-weight codes, besides the first order Reed-Muller codes, is also determined.

Imagining a nation: Cultural politics and transformative social action among late-twentieth century African-American women

description: Social science rarely studies African American women's socio-political activism and acts of "everyday resistance." Even though 66 percent of Blacks belong to middle- or upper-socio-economic groups, anthropology's research concerning African-American women usually represents them as impoverished, powerless and passive victims of social inequities and in ways that confirm racial stereotypes. This study of middle- and upper-class Black women's use of cultural political strategies, including ethnic identification, cultural symbols, social affiliations, hegemonic discourse and participation in transformative social action is framed by three theoretical concepts: First, emphasizing ethnicity can effect social change; second, cultural symbols and social affiliations have political functions; and third, self-help social activism, everyday talk and practices which deny dominant ideas and offer alternative explanations are forms of political resistance. Research for this dissertation involved collecting data from fifty-five African American women (ages twenty-one through ninety-one years old, 57 percent with masters or doctoral college degrees) from all national regions. Research methods included focused personal interviews, reviews of popular cultural media the women read or watched (e.g., Essence magazine and the Essence Awards Ceremonies) and participant observation at meetings and ceremonies of their social affiliations (e.g., the National Council of Negro Women, national Protestant denominational conventions and local church services). Texts from these sources were subjected to trope, narrative and discourse analysis. Comparison of the experiential tropes in texts of women by generation of birth---Generation I (1900--1920), Generation II (1921--1940), Generation III (1941--1960) and Generation IV (born after 1960)---found that women who were exposed to a greater emphasis on ethnicity in early life reported several common experiences. These include: fewer incidences of race-based discrimination as influencing their self identification; differences in the political strategies they advocated or used, and in their perceived arena of political influence. Discourse analysis of the interviews, meetings and media texts suggests that these women and others like them are constructing an "Imagined Nation" on an ideological terrain through production of crosscutting class and gender alliances, a unified national/transnational consciousness, and expropriation of symbolic and material modes of subordination. These strategies prepare them to be powerful social forces in a leading class forming an alternative hegemony in coming years modifying capitalism to bring social equity for all people, especially people of color world-wide.

description: Objective: To investigate if food security mediated the impact of a nutrition-sensitive agroecology intervention on womens depressive symptoms. Design: We used annual longitudinal data (4 time points) from a cluster-randomized effectiveness trial of a nutrition-sensitive agroecology intervention, the Singida Nutrition and Agroecology Project. Structural equation modeling estimation of total, natural direct, and natural indirect effects was used to investigate food securitys role in the interventions impact on womens probable depression (CES-D > 17) over three years.  Setting: Rural Singida, Tanzania. Participants: 548 food insecure, married, smallholder women farmers with children < 1-year-old at baseline. Results: At baseline, one third of the women in each group had probable depression (Control: 32.0%, Intervention: 31.9%, p-difference=0.97). The intervention lowered odds of probable depression by 43% (OR=0.57, 95% CI: 0.43-0.70).  The effect of the intervention on probable depression that was due to differences in food security was approximately 10% (OR = 0.90, 95% CI: 0.83-0.95).  Conclusions: Nutrition-sensitive agricultural interventions can have broader impacts than previously demonstrated, i.e., on mental health, and food security plays an important causal role in this pathway. These data suggest nutrition-sensitive agriculture interventions have the potential to reduce the loss of quality life years for women in farming communities. Future agricultural and nutrition projects should include mental health evaluations to determine generalizability.

description: In cold atomic gases the interactions between the atoms are directly controllable through external magnetic fields. The magnetic field control is typically performed indirectly by stabilizing the current through a pair of Helmholtz coils, which produce this large bias field. Here, we overcome the limitations of such an indirect control through a direct feedback scheme, which is based on nitrogen-vacancy centers acting as a magnetic field sensor. This allows us to measure and stabilize fields of 4.66 mT down to 12 nT RMS noise over the course of 24 h, measured on a 1 Hz bandwidth. We achieve a control of better than 1 ppm after 20 minutes of integration time, ensuring high long-term stability for experiments. This approach extends direct magnetic field control to strong magnetic fields, which could enable new precise quantum simulations in this regime.

In this paper we have analyzed the possibilities of developing the concept of determinant of matrices with three indexed 3D Matrices. We define the concept of determinant for cubic-matrix of order 2 and order 3, study and prove some basic properties for calculations of determinants of cubic-matrix of order 2 and 3. Furthermore we have also tested several square determinant properties and noted that these properties also are applicable on this concept of 3D Determinants.

description: In this study we attempt to demonstrate that market penetration of newly developed technologies or durable goods is slower and to a lower extent compared to those of the initial technology and durable that yielded similar services (color TV vs. BWTV). Government intervention in the form of licensing has a similar effect. When substitution and regulation occur simultaneously the identification of the independent role of each in the observed slower and lower adoption require detailed information we do not have (cable TV).

Schwinger Effect from Near-extremal Black Holes in (A)dS Space
Creators: name: Chen, Chiang-Mei

Subjects: subject: High Energy Physics - Theory (hep-th)

description: We study the Schwinger effect in near-extremal Reissner-Nordström (RN) black holes with electric and/or magnetic charges in the (Anti-) de Sitter (AdS) space. The formula for the Schwinger effect takes a universal form for near-extremal black holes with the near-horizon geometry of ${\rm AdS}_2 \times S^2$ and with the proper radii for the ${\rm AdS}_2$ space and the two-sphere $S^2$, regardless of the asymptotically flat or (A)dS space. The asymptotic AdS boundary enhances and the dS boundary suppresses the Schwinger effect and the small radius of the AdS (dS) space reinforces the enhancement and suppression.

description: We develop and solve a network of rate equations for the production of baryons and anti-baryons in high energy nuclear collisions. We include all members of the baryon octet and decuplet and allow for transformations among them. This network is solved during a relativistic 2+1 hydrodynamical expansion of the of the hot matter created in the collision. As an application we compare to the number of protons, lambdas, negative cascades, and omega baryons measured at mid-rapidity in central collisions of gold nuclei at 65 GeV per nucleon at the Relativistic Heavy Ion Collider (RHIC).

Extreme boundary conditions and random tilings

description: Standard statistical mechanical or condensed matter arguments tell us that bulk properties of a physical system do not depend too much on boundary conditions. Random tilings of large regions provide counterexamples to such intuition, as illustrated by the famous 'arctic circle theorem' for dimer coverings in two dimensions. In these notes, I discuss such examples in the context of critical phenomena, and their relation to 1+1d quantum particle models. All those turn out to share a common feature: they are inhomogeneous, in the sense that local densities now depend on position in the bulk. I explain how such problems may be understood using variational (or hydrodynamic) arguments, how to treat long range correlations, and how non trivial edge behavior can occur. While all this is done on the example of the dimer model, the results presented here have much greater generality. In that sense the dimer model serves as an opportunity to discuss broader methods and results. [These notes require only a basic knowledge of statistical mechanics.]

The politics of inter -Korean negotiations, 1971--1992
Creators: name: Cho, Yun Young
Publisher: name: American University
Year: 2023

description: This study investigates the impact of significant domestic political changes in South and North Korea on inter-Korean negotiations between 1971 through 1992. Since the armistice agreement in 1953, there have been three major periods of negotiations between South and North Korea. The first period began with the Joint Communique in the early 1970s, the second took place in the middle of 1980s, and the third occurred in the late 1980s and early 1990s, when Seoul and Pyongyang signed the Basic Agreement and Joint Declaration. Why did South-North Korean negotiations take place at these particular times? What factors were most influential in determining the outcome of the negotiations? Many scholars emphasize the importance of politics in negotiations, but what level of politics is most important analytically? If domestic politics is a major factor in inter-Korean negotiations, which domestic political phenomena have the most significant impact? What is the real role of negotiation in inter-Korean relations?; This dissertation seeks to answer these questions through a synthesis of the realist and conflict resolution approaches that concentrates on the impact of domestic politics, the international environment, and inter-Korean relations on negotiation. It also analyzes the two parties' interests, objectives, strategies and tactics. In contrast to much existing literature, this study argues that domestic political forces have had a greater influence on inter-Korean relations and negotiations than the international environment. While the paper does not minimize the importance of international factors, it suggests that domestic factors are generally more significant for the negotiation and implementation of agreements. Simultaneous significant political changes in South and North Korea were particularly important to the substance and ripeness of the three major inter-Korean negotiations. Ultimately, political leaders in South and North Korea took advantage of changes in the international environment to consolidate their political power through high-profile, security-oriented talks. Thus, rather contributing to a resolution of the conflict between the two Koreas, inter-Korean negotiations were often merely a tool serving each side's domestic political goals.
Two-Loop g -> gg Splitting Amplitudes in QCD

description: Splitting amplitudes are universal functions governing the collinear behavior of scattering amplitudes for massless particles. We compute the two-loop g -> gg splitting amplitudes in QCD, N=1, and N=4 super-Yang-Mills theories, which describe the limits of two-loop n-point amplitudes where two gluon momenta become parallel. They also represent an ingredient in a direct x-space computation of DGLAP evolution kernels at next-to-next-to-leading order. To obtain the splitting amplitudes, we use the unitarity sewing method. In contrast to the usual light-cone gauge treatment, our calculation does not rely on the principal-value or Mandelstam-Leibbrandt prescriptions, even though the loop integrals contain some of the denominators typically encountered in light-cone gauge. We reduce the integrals to a set of 13 master integrals using integration-by-parts and Lorentz invariance identities. The master integrals are computed with the aid of differential equations in the splitting momentum fraction z. The epsilon-poles of the splitting amplitudes are consistent with a formula due to Catani for the infrared singularities of two-loop scattering amplitudes. This consistency essentially provides an inductive proof of Catani's formula, as well as an ansatz for previously-unknown 1/epsilon pole terms having non-trivial color structure. Finite terms in the splitting amplitudes determine the collinear behavior of finite remainders in this formula.
