description: Andrena (Micrandrena) piperi Viereck, 1904
[Holotype: UNSM; ♀ Pullman, Washington, US]
This species has a broad distribution across the southwestern USA and northern BC. This species has a strong preference for pollen from plants in the family Brassicaceae Ribble (1967). Within the BCP, its presence was first documented in BC’s Succulent Coastal Matorral (Ribble, 1968). We reviewed one female collected in April 1963 in the Chaparral region south of Tecate and confirmed a female reported by Ribble (1968) from the Succulent Coastal Matorral in April 1963 (CASC). Additionally, the BBPT collected 12 females in the Coastal Sage Matorral in March (1) and April (11) of 2021. Voucher specimens are in BBSL, ECOAB, and MABC. See fig. 15.

description: We investigate dynamic scaling properties of the two-dimensional gauge glass model for the vortex glass phase in superconductors with quenched disorder. From extensive Monte Carlo simulations we obtain static and dynamic finite size scaling behavior, where the static simulations use a temperature exchange method to ensure convergence at low temperatures. Both static and dynamic scaling of Monte Carlo data is consistent with a glass transition at zero temperature. We study a dynamic correlation function for the superconducting order parameter, as well as the phase slip resistance. From the scaling of these two functions, we find evidence for two distinct diverging correlation times at the zero temperature glass transition. The longer of these time scales is associated with phase slip fluctuations across the system that lead to finite resistance at any finite temperature, while the shorter time scale is associated with local phase fluctuations.

description: We report the discovery of superconductivity at about 4.3 K in the samarium doped 1,3,5-triphenylbenzene. By using a solid state reaction method, the samarium doped 1,3,5-triphenylbenzene samples are successfully synthesized. These samples are characterized by magnetization, X-ray diffraction (XRD), scanning electron microscope(SEM) and energy dispersive spectroscopy (EDS) measurements. The X-ray diffractions reveal that the sample crystallizes in a space group of $P2/m$. The magnetization measurements reveal a superconducting transition at about 4.3 K. However, the superconducting shielding fraction is only about 1%, which is similar to the previous reports of the superconductivity in other aromatic hydrocarbons. Magnetization hysteresis loops (MHLs) of the sample show that it is a typical type-II superconductor.

description: We revisit the issue of directed motion induced by zero average forces in extended systems driven by ac forces. It has been shown recently that a directed energy current appears if the ac external force, $f(t)$, breaks the symmetry $f(t) = - f(t+T/2)$, $T$ being the period, if topological solitons (kinks) existed in the system. In this work, a collective coordinate approach allows us to identify the mechanism through which the width oscillation drives the kink and its relation with the mathematical symmetry conditions. Furthermore, our theory predicts, and numerical simulations confirm, that the direction of motion depends on the initial phase of the driving, while the system behaves in a ratchet-like fashion if averaging over initial conditions. Finally, the presence of noise overimposed to the ac driving does not destroy the directed motion; on the contrary, it gives rise to an activation process that increases the velocity of the motion. We conjecture that this could be a signature of resonant phenomena at larger noises.

title: The Problem Of Human Subjectivity In Hegel's Thought, With Particular Regard To The Relationship Between Hegel's Early Theological Writings And His Mature Philosophy Of Religion
Creators: name: Hodgson, Michael John Christopher
Publisher: name: The Open University
Year: 1998

description: I seek, in this thesis, by means of a critical exposition and comparison of Hegel’s Early Theological Writings and his mature Lectures on the Philosophy of Religion, to elucidate the relationship between human subjectivity, the self-conscious experience of humanity and the absolute truth which is absolute spirit, God. The apparent divorce of positive biblical narrative from its reflective interpretation is not, it is to be argued, the result of the importing of critical philosophy into the domain of Christian experience. Rather, it is intrinsic to that very experience. The tension between positivity and inwardness, so central a problem to the concerns of the earlier philosophy has, by the time of the mature philosophy of religion, become an opportunity, rather than just a problem, for Christianity. Understanding the continuity between Hegel’s Early Theological Writings and the ostensibly very different speculative system, also enables one to understand the relevance of both to contemporary (and especially religious) experience.

description: Chaotic inflation on the brane is considered in the context of stochastic inflation. It is found that there is a regime in which eternal inflation on the brane takes place. The corresponding probability distributions are found in certain cases. The stationary probability distribution over a comoving volume and the creation probability of a de Sitter braneworld yield the same exponential behaviour. Finally, nonperturbative effects are briefly discussed.

description: This report presents findings from a larger quantitative study about New Zealand adults’ experiences of harmful digital communications. The report focuses on the prevalence of image-based sexual abuse (IBSA), and people’s attitudes regarding different aspects of it. The findings described in this report are based on data collected from a nationally representative sample. We conducted a survey-based study with 1,001 adult New Zealanders. Fieldwork took place between 30 May and 1 July 2018. The objectives of the IBSA questionnaire were to gauge prevalence among adult New Zealanders: both self-reported personal experiences and involvement with this behaviour. It also sought to explore participants’ level of agreement with IBSA related issues. The margin of error for this study was +/- 3.1% at a 95% confidence level on total results. This study is the first of its kind conducted in New Zealand.

description: We describe a first step for identifying foreign markets that may be candidates for export expansion. The method compares export data to the amount of exports predicted by the gravity equation. We estimate four sets of gravity equation coefficients and use both in-sample and outof- sample predictions. To illustrate our method, we use data from Washington agricultural industrial groups. We find many markets, particularly those in Europe, that are currently underserved by Washington agricultural exports, often by large amounts. We also identify overserved markets that can be further studied to provide lessons on what works for increasing exports.

description: Under certain conditions, a $(1+1)$-dimensional slice $\hat{g}$ of a spherically symmetric black hole spacetime can be equivariantly embedded in $(2+1)$-dimensional Minkowski space. The embedding depends on a real parameter that corresponds physically to the surface gravity $κ$ of the black hole horizon. Under conditions that turn out to be closely related, a real surface that possesses rotational symmetry can be equivariantly embedded in 3-dimensional Euclidean space. The embedding does not obviously depend on a parameter. However, the Gaussian curvature is given by a simple formula: If the metric is written $g = ϕ(r)^{-1} dr^2 + ϕ(r) dθ^2$, then $\K_g=-{1/2}ϕ''(r)$. This note shows that metrics $g$ and $\hat{g}$ occur in dual pairs, and that the embeddings described above are orthogonal facets of a single phenomenon. In particular, the metrics and their respective embeddings differ by a Wick rotation that preserves the ambient symmetry. Consequently, the embedding of $g$ depends on a real parameter. The ambient space is not smooth, and $κ$ is inversely proportional to the cone angle at the axis of rotation. Further, the Gaussian curvature of $\hat{g}$ is given by a simple formula that seems not to be widely known.

An analysis of voter opinion on the merits of principal arguments for increasing the operating tax levy for Jefferson College
Creators: name: Watts, Wayne Howard
Publisher: name: American University
Year: 2023

description: The purposes of this study were: (1) to assess the extent of agreement by a sample of Jefferson County voters with ten principal arguments for increasing the operating tax levy for Jefferson College; (2) to ascertain differences in the extent of agreement with these arguments by voters classified by gender, age, income and county region; and (3) to interpret the findings for their utility to College officials in developing campaign strategies related to a voter referendum. In a telephone interview utilizing the Structured Interview Protocol (SIP), developed for this study by the researcher, a random sample of 301 Jefferson County voters were asked to respond to ten principal arguments in terms of their persuasiveness for increasing the operating tax levy for Jefferson College. The extent of voter agreement with each argument was assessed using a five alternative Likert-type response scale. Additionally, voter gender, age, income and county region of residence were elicited as classificatory information. The data generated through the SIP were statistically analyzed using cross-tabulation procedures for frequencies and percentages and t-test and F-tests to determine the significance of the differences in the extent of agreement for each principal argument within classification of voters. This study found that the voters sampled were in substantial agreement that none of the principal arguments was a persuasive reason to support an increase in the operating tax levy for Jefferson College. Furthermore, analysis of the relationship between voter classification by gender, age, income and county region of residence and extent of voter agreement with the ten arguments produced no significant results. It is noteworthy that about one-third to one-fifth of the voters responded "undecided" about the persuasiveness of nine of the ten arguments. It was concluded that a publicity/educational campaign to influence voters to support a referendum to increase Jefferson College's tax levy is imperative to its success and should appeal to the general populace and not specific audiences in Jefferson County. Further, the large number of "undecided" voters should be seen as having the balance of power in the tax levy referendum.

description: The partial copula provides a method for describing the dependence between two random variables $X$ and $Y$ conditional on a third random vector $Z$ in terms of nonparametric residuals $U_1$ and $U_2$. This paper develops a nonparametric test for conditional independence by combining the partial copula with a quantile regression based method for estimating the nonparametric residuals. We consider a test statistic based on generalized correlation between $U_1$ and $U_2$ and derive its large sample properties under consistency assumptions on the quantile regression procedure. We demonstrate through a simulation study that the resulting test is sound under complicated data generating distributions. Moreover, in the examples considered the test is competitive to other state-of-the-art conditional independence tests in terms of level and power, and it has superior power in cases with conditional variance heterogeneity of $X$ and $Y$ given $Z$.

description: The statistical properties of pairwise majority voting over S alternatives is analyzed in an infinite random population. We first compute the probability that the majority is transitive (i.e. that if it prefers A to B to C, then it prefers A to C) and then study the case of an interacting population. This is described by a constrained multi-component random field Ising model whose ferromagnetic phase describes the emergence of a strong transitive majority. We derive the phase diagram, which is characterized by a tri-critical point and show that, contrary to intuition, it may be more likely for an interacting population to reach consensus on a number S of alternatives when S increases. This effect is due to the constraint imposed by transitivity on voting behavior. Indeed if agents are allowed to express non transitive votes, the agents' interaction may decrease considerably the probability of a transitive majority.

description: We report the discovery of eight new extremely metal-poor galaxies (XMPGs; 12+log(O/H) < 7.65) and the recovery of four previously known or suspected XMPGs (IZw18, HS0822+3542, HS0837+4717 and A1116+517) using Sloan Digital Sky Survey (SDSS) spectroscopy. These new objects were identified after an analysis of 250,000 galaxy spectra within an area of ~3000 deg^2 on the sky. Our oxygen abundance determinations have an accuracy of $\le$ 0.1 dex and are based on the temperature-sensitive [O {\sc iii}] $λ$4363 Åline and on the direct calculation of the electron temperature. We briefly discuss a new method of oxygen abundance determinations using the [O {\sc ii}] $λ$7319,7330 Å lines, which is particularly useful for SDSS emission-line spectra with redshifts $\le$~0.024 since the [O {\sc ii}] $λ$3727 Åemission line falls outside of the SDSS wavelength range. We detect XMPGs with redshifts ranging from 0.0005 to 0.0443 and $M_g$ luminosities from $-$12\fm4 to $-$18\fm6. Our eight new XMPGs increase the number of known metal-deficient galaxies by approximately one quarter. The estimated surface density of XMPGs is 0.004 deg$^{-2}$ for $r$ $\le$ 17\fm77.

description: Considerable research has demonstrated the connections between food deserts, dietary outcomes, and chronic diseases. Less research exists on upstream challenges that could play a role in the creation and perpetuation of food deserts. This study examines barriers to supplying affordable produce to food deserts. We conducted expert interviews with channel members of a regional produce supply chain to reveal perceived supply chain barriers, which included high distribution costs, lack of perceived consumer demand, and failure to achieve scale economies. Opportunities identified included providing strategic economic incentives, improving retail infrastructure, and working with novel distribution mechanisms such as food hubs.

description: In this work, we study the mechanics of metamaterial sheets inspired by the pellicle of Euglenids. They are composed of interlocking elastic rods which can freely slide along their edges. We characterize the kinematics and the mechanics of these structures using the special Cosserat theory of rods and by assuming axisymmetric deformations of the tubular assembly. Through an asymptotic expansion, we investigate both structures that comprise a discrete number of rods and the limit case of a sheet composed by infinitely many rods. We apply our theoretical framework to investigate the stability of these structures in the presence of an axial load. Through a linear analysis, we compute the critical buckling force for both the discrete and the continuous case. For the latter, we also perform a numerical post-buckling analysis, studying the non-linear evolution of the bifurcation through finite elements simulations.
The effects of a 36-hour Marine Corps substance abuse awareness seminar on supervisors' knowledge and perceptions of an employee alcoholism program
Creators: name: Baker, Kay Louise
Publisher: name: American University
Year: 2023

description: This study investigated the effects of the 36-hour Marine Corps Substance Abuse Awareness Seminar on the knowledge and perceptions of supervisors, as assessed by the Baker Knowledge Inventory and the Demographic Information Inventory, before and after substance abuse training, and compared these results with a similar group of supervisors who had not participated in the seminar. The primary component of knowledge assessed in this study was knowledge of the Marine Corps Substance Abuse Program, and the perceptions assessed in this study were perceptions of the confidentiality, staff competence, effectiveness, and management support for the Marine Corps Substance Abuse Program. A quasi-experimental, pretest/posttest design, with a 126-subject experimental and 39-subject control group, was used. Four hypotheses were tested using dependent and independent one- and two-tailed t tests, with the following results: no significant difference existed between the mean pretest scores for the two groups; no significant difference existed between the mean pretest and posttest scores for the control group; the experimental group's mean posttest score was significantly higher than the control group's mean posttest score; and the experimental group's mean posttest score was significantly higher than their mean pretest score. Additional data analysis revealed that the experimental group's mean posttest scores on the knowledge scale and the perception scale, taken separately, were significantly higher than its mean pretest scores on the same scales, taken separately. From the results of hypothesis testing and ad hoc data analysis, the researcher concluded that supervisory training was a means of significantly improving supervisors' knowledge and perceptions of an Employee Assistance Program.

description: Ve present a simple overlapping generations search model of an inflationary economy in which money is the only store of value and identify an inflation based endogenously determined search cost. The latter reflects the fact that resources required for future consumption are random and are thus exposed to excessive erosion. Ve analyze the effect of the constant inflation rate on the equilibrium real price distribution, output and welfare. An increase in the rate of inflation increases production efficiency and may increase welfare.

description: This study investigated the effects of the 36-hour Marine Corps Substance Abuse Awareness Seminar on the knowledge and perceptions of supervisors, as assessed by the Baker Knowledge Inventory and the Demographic Information Inventory, before and after substance abuse training, and compared these results with a similar group of supervisors who had not participated in the seminar. The primary component of knowledge assessed in this study was knowledge of the Marine Corps Substance Abuse Program, and the perceptions assessed in this study were perceptions of the confidentiality, staff competence, effectiveness, and management support for the Marine Corps Substance Abuse Program. A quasi-experimental, pretest/posttest design, with a 126-subject experimental and 39-subject control group, was used. Four hypotheses were tested using dependent and independent one- and two-tailed t tests, with the following results: no significant difference existed between the mean pretest scores for the two groups; no significant difference existed between the mean pretest and posttest scores for the control group; the experimental group's mean posttest score was significantly higher than the control group's mean posttest score; and the experimental group's mean posttest score was significantly higher than their mean pretest score. Additional data analysis revealed that the experimental group's mean posttest scores on the knowledge scale and the perception scale, taken separately, were significantly higher than its mean pretest scores on the same scales, taken separately. From the results of hypothesis testing and ad hoc data analysis, the researcher concluded that supervisory training was a means of significantly improving supervisors' knowledge and perceptions of an Employee Assistance Program.

description: The probability distribution for vacuum fluctuations of the energy flux in two dimensions will be constructed, along with the joint distribution of energy flux and energy density. Our approach will be based on previous work on probability distributions for the energy density in two dimensional conformal field theory. In both cases, the relevant stress tensor component must be averaged in time, and the results are sensitive to the form of the averaging function. Here we present results for two classes of such functions, which include the Gaussian and Lorentzian functions. The distribution for the energy flux is symmetric, unlike that for the energy density. In both cases, the distribution may possess an integrable singularity. The functional form of the flux distribution function involves a modified Bessel function, and is distinct from the shifted Gamma form for the energy density. By considering the joint distribution of energy flux and energy density, we show that the distribution of energy flux tends to be more centrally concentrated than that of the energy density. We also determine the distribution of energy fluxes, conditioned on the energy density being negative. Some applications of the results will be discussed.

description: Armenian survivors of the 1915-1923 genocide committed by the Turkish government against the Armenians and other Christian minorities in Turkey were compared to a control group of elderly Armenians who did not experience the genocide. Both groups were assessed for symptoms of post-traumatic stress disorder (PSTD) via the Structured Clinical Interview for DSM-III-R (SCID) - PTSD module, and for current adaptation via the Tennessee Self-Concept Scale (TSCS), the Life Satisfaction Scale (LSI), and the Brief Symptom Inventory (BSI). In addition, both groups were assessed for post-traumatic reactions to recent news of anti-Armenian violence from Turkic Azeris via the Impact of Event Scale (IES). By assessment with the SCID, 3 of 34 survivors and 0 of 34 control subjects were diagnosed with PTSD. Although both groups were equally unlikely to have PTSD, the survivor group had significantly more positive symptoms of PTSD than the control group. This confirms the hypothesis that PTSD symptoms would linger, even eight decades, and therefore be higher in survivors than controls. PTSD symptoms, past and present, were further examined by type of symptom. Survivors met criteria for significantly more present intrusion symptoms, and tended to report more avoidance symptoms. In the past, avoidance symptoms were significantly higher for survivors than control subjects. Between group differences were found on one of three global BSI scales, with control subjects unexpectedly reporting a greater number of symptoms. No between group differences were found on the Total TSCS, LSI, or IES, indicating that, contrary to hypothesis, survivors had a similar sense of life satisfaction and self-esteem, and were not more sensitized to current anti-Armenian violence than controls. These assessments indicate that survivors had adjusted as well as the control group, despite their higher trauma symptomatology. An unexpected finding was an indication of higher pathology on the BSI and the somatic category of PTSD symptoms among those controls who were the grandchildren of survivors from earlier pogroms, as compared to other controls. Conclusions are that post-traumatic stress symptomatology can continue eight decades, as evidenced in the survivor group, but that, overall, this survivor sample appears to have adjusted as well as a control sample of elderly Armenians.
Synchronization and partial synchronization of linear maps

description: We study synchronization of low-dimensional ($d=2,3,4$) chaotic piecewise linear maps. For Bernoulli maps we find Lyapunov exponents and locate the synchronization transition, that numerically is found to be discontinuous (despite continuously vanishing Lyapunov exponent(s)). For tent maps, a limit of stability of the synchronized state is used to locate the synchronization transition that numerically is found to be continuous. For nonidentical tent maps at the partial synchronization transition, the probability distribution of the synchronization error is shown to develop highly singular behavior. We suggest that for nonidentical Bernoulli maps (and perhaps some other discontinuous maps) partial synchronization is merely a smooth crossover rather than a well defined transition. More subtle analysis in the $d=4$ case locates the point where the synchronized state becomes stable. In some cases, however, a riddled basin attractor appears, and synchronized and chaotic behaviors coexist. We also suggest that similar riddling of a basin of attractor might take place in some extended systems where it is known as stable chaos.

description: We briefly compare in numerical simulations the relativistic ionization front and electron bunch seeding of the self-modulation of a relativistic proton bunch in plasma. When parameters are such that initial wakefields are equal with the two seeding methods, the evolution of the maximum longitudinal wakefields along the plasma are similar. We also propose a possible seeding/injection scheme using a single plasma that we will study in upcoming simulations works.

description: Parents are key players in relation to the online safety of their children. However, while evidence shows that New Zealand teens regard their parents as the first line of support in dealing with online risks and challenges, parents seem to underestimate or be unaware of the frequency of such risks. This report presents findings from a larger quantitative study about parenting, digital technologies and online risks. It focuses on parents and caregivers’ awareness and attitudes towards their child’s access and exposure to sexually explicit content, both deliberately and/or accidentally, in the prior year. We conducted a quantitative survey with parents/whānau (and caregivers) of children aged 9 to 17 years old. The study was conducted in New Zealand based on a nationally representative sample. Our findings show that parents’ main online concerns are their children sharing nudes of themselves, being treated in a hurtful way, and seeing sexually explicit content. Also, the study found that 1 in 5 parents said their children were exposed to sexually explicit content online in the prior year.

description: Axisymmetric permanent magnets become electrically polarized due to their rotation around the symmetry axis. This phenomenon is considered in detail for both conducting and dielectric magnets. The results are applied to the Earth which is predicted to be electrically polarized. It is suggested that this polarization can be detected in a tethered satellite experiment.
Simultaneous Charge Ordering and Spin Dimerization in Quasi-Two-Dimensional Quarter-Filled Ladders

description: We study the spin-pseudospin Hamiltonian of the Ising Model in Transverse Field (IMTF) for pseudospins, coupled to the XY-spins on a triangular lattice. This model appears from analyses of the quarter-filled ladder compound $NaV_2O_5$, and pseudospins represent its charge degrees of freedom. In the molecular-field approximation we find that the model possesses two phases: charge-disordered without spin gap; and a low-temperature phase containing both the anti-ferroelectric (zigzag) charge order and spin dimerization (spin gap). The phase transition is of the second kind, and the calculated physical quantities are as those one expects from the Landau theory. One of particular features of the phase diagram is that the inter-ladder spin-pseudospin coupling, responsible for the spin gap generation, also destroys the IMTF quantum critical point, resulting in the exponential behavior of $T_c$ in the region of Ising's coupling where the IMTF is always disordered. We conclude that our mean-field results give a qualitatively correct description of the phase transition in $NaV_2O_5$, while a more sophisticated analysis is warranted in order to take into account the thermal fluctuations and, probably, the proximity of the IMTF quantum critical point.

description: This report presents findings from a larger quantitative study about New Zealand adults’ experiences of harmful digital communications. The report focuses on the prevalence of image-based sexual abuse (IBSA), and people’s attitudes regarding different aspects of it. The findings described in this report are based on data collected from a nationally representative sample. We conducted a survey-based study with 1,001 adult New Zealanders. Fieldwork took place between 30 May and 1 July 2018. The objectives of the IBSA questionnaire were to gauge prevalence among adult New Zealanders: both self-reported personal experiences and involvement with this behaviour. It also sought to explore participants’ level of agreement with IBSA related issues. The margin of error for this study was +/- 3.1% at a 95% confidence level on total results. This study is the first of its kind conducted in New Zealand.
