description: Scalar mediated interactions among baryons extend well above the Compton wavelength, when they are embedded in a Bose-Einstein condensate composed of the mediating particles. Indeed, this non-trivial environment results in an infinite-ranged interaction. We show that if the Dark Matter of the Universe is composed of such a condensate, the imprints of an interaction between baryonic and Dark Matter could be manifest as anomalies in the peak structure of the Cosmic Microwave Background.

E W Bullinger debunked: How Bullinger's analysis ignored disconfirming evidence

subject: FOS: Philosophy, ethics and religion

description: In 1894 Anglican cleric E W Bullinger published 'Number in Scripture' arguing that Biblical numbers and pronouns demonstrated unusual, non-random patterns which supported the Bible's inspiration and provided a deeper layer of meaning to biblical interpretation. For over a century Bullinger's findings have been accepted across orthodox, evangelical and non-conformist Christianity with apparent lack of criticism or peer review. This article summarises extensive checks on Bullinger's mathematics the results of which show his methodology is flawed on a number of grounds. These findings were so surprising, the editor included a cautious caveat at the end inviting falsification. To date none has been received. After dissemination and checks on Google Scholar and Wikipedia it seems no material has been published with these findings. This article seeks to explain straightforwardly the errors made by Bullinger regardless of whether the reader accepts or rejects biblical inspiration.

description: We consider a class of 4D supersymmetric black hole solutions, arising from string theory compactifications, which classically have vanishing horizon area and singular space-time geometry. String theory motivates the inclusion of higher derivative terms, which convert these singular classical solutions into regular black holes with finite horizon area. In particular, the supersymmetric attractor equations imply that the central charge, which determines the radius of the $AdS_2\times S^2$ near horizon geometry, acquires a non-vanishing value due to quantum effects. In this case quantum corrections to the Bekenstein-Hawking relation between entropy and area are large. This is the first explicit example where stringy quantum gravity effects replace a classical null singularity by a black hole with finite horizon area.

description: This research examines selected empirical properties of duality relationships. Monte Carlo experiments indicate that Hessian matrices estimated from the normalised unrestricted profit, restricted profit and production functions yield conflicting results in the presence of measurement error and low relative price variability. In particular, small amounts of measurement error in quantity variables can translate into large errors in uncompensated estimates calculated via restricted and unrestricted profit and production functions. These results emphasise the need for high quality data when estimating empirical models in order to accurately determine dual relationships implied by economic theory.

description: The importance of the investigation of magnetic superstorms is not limited to academic interest, because these superstorms can cause catastrophic impact on the modern civilisation due to our increasing dependency on technological infrastructure. In this context, the Carrington storm in September 1859 is considered as a benchmark of observational history owing to its magnetic disturbance and equatorial extent of the auroral oval. So far, several recent auroral reports at that time have been published but those reports are mainly derived from the Northern Hemisphere. In this study, we analyse datable auroral reports from South America and its vicinity, assess the auroral extent using philological and astrometric approaches, identify the auroral visibility at - 17.3° magnetic latitude and further poleward and reconstruct the equatorial boundary of the auroral oval to be 25.1° +/- 0.5° in invariant latitude. Interestingly, brighter and more colourful auroral displays were reported in the South American sector than in the Northern Hemisphere. This north-south asymmetry is presumably associated with variations of their magnetic longitude and the weaker magnetic field over South America compared to the magnetic conjugate point and the increased amount of magnetospheric electron precipitation into the upper atmosphere. These results attest that the magnitude of the Carrington storm indicates that its extent falls within the range of other superstorms, such as those that occurred in May 1921 and February 1872, in terms of the equatorial boundary of the auroral oval.

Grown-ups have careers : discourses of career and adulthood in four urban Vancouver high schools
Creators: name: Benjamin, Amanda Joy
Publisher: name: University of British Columbia
Year: 2010

description: In British Columbia, the career education curriculum from 1995-2003 was Career and Personal Planning (CAPP). The premise of CAPP was that if schools provided students with generic and specific skills, these students would be more likely to find and retain careers and become successful members of an adult community. However, one of the problems with the rapid development of career education programs like CAPP is a lack of discussion about the content and pedagogy of such curricula. With tacit inclusion of these programs, it is important to ask questions about whose values and interests are being served by career programs in schools. Accordingly, this research focuses on how programs like CAPP contribute to shaping both students’ and teachers’ perceptions of what it means to have a career and be an adult. The purpose of this research was to undertake a critical examination of the BC CAPP curriculum through document analysis, interviews with teachers and students, and classroom observations, in order to illuminate how career and adulthood were constituted. Four Vancouver high schools were chosen as the sites of this inquiry. In using a discourse oriented approach, this research analyzed how teachers and students talked. The findings revealed several prominent discourses in the CAPP curriculum and how these discourses reproduced and resisted ideological and hegemonic understandings of career and adulthood. This study outlines the various ways that CAPP was implemented across four schools, how jobs and careers were constructed in ways that privileged some post high school pathways, while at the same time differentiated others based on social class, and how career influenced understandings of adulthood. The conclusion highlights the need for career education that provides more information about possible post high school destinations as well as a critical orientation to the relationship between education, credentials and the labour market. This work has implications for curriculum developers and teachers of career education because it illustrates the values that are reproduced and resisted in career education classrooms. In particular, this study contributes to a larger discussion of how schools and curricula are implicated in reproducing class, gender and racial differentiation.

description: Practical multiple-input-multiple-output (MIMO) systems depend on a predefined set of precoders to provide spatial multiplexing gain. This limitation on the flexibility of the precoders affects the overall performance. Here, we propose a transmission scheme that can reduce the effect of mismatch between users' channels and precoders. The scheme uses the channel knowledge to generate an artificial signal, which realigns the predefined precoder to the actual channel. Moreover, the scheme can provide an additional level of secrecy for the communication link. The performance of the proposed scheme is evaluated using bit-error rate (BER), error vector magnitude (EVM), and secrecy capacity. The results show a significant improvement for the legitimate user, along with a degradation for the eavesdropper.

description: Aims: To assess the change in body condition score (BCS) during the early and late dry periods and its association with postpartum diseases and milk yield in grazing dairy cows from central Argentina. Methods: BCS assessments during the dry period, and cow health and milk production records up to 90 days in milk (DIM), were collated for cows from 28 farms at monthly visits between 2007 and 2008. Cows were categorised into four groups; those in Group 1 (n=7,067) maintained or gained BCS during the early and late dry periods; Group 2 (n=2,615) maintained or gained BCS during the early dry period and lost BCS during the late dry period; Group 3 (n=1,989) lost BCS during the early dry period and maintained or gained BCS during the late dry period; and Group 4 (n=5,144) lost BCS during the early and late dry periods. Results: Cows in Group 1 had reduced odds of having retained fetal membranes (RFM), metritis, and clinical mastitis up to 90 DIM than cows in Group 2 (p<0.001), but the odds of disease were similar to cows in Group 3. The odds of having RFM or clinical mastitis tended to be lower in cows in Group 1 than cows in Group 4 (p=0.08). The odds of cows being culled or dying during the first 90 DIM were lower for cows in Group 1 than for those in Groups 2, 3, and 4 (p≤0.05). Mean accumulated milk yield up to 90 DIM was higher in cows in Group 1 than Group 2 and Group 4 (p<0.001), but was similar to that of cows in Group 3 (p=0.28). Conclusions and clinical relevance: Cows that lost BCS during the late dry period had increased odds of being diagnosed with several postpartum diseases and had decreased milk yield compared to cows that maintained or gained BCS during the entire dry period. Loss of BCS during any stage of the dry period was also associated with increased incidence of culling or death during the first 90 DIM. These results should raise awareness among dairy cattle producers of the importance of properly managing cow body condition during the dry period, especially during the late dry period.

description: The resilience of quantum entanglement to a classicality-inducing environment is tied to fundamental aspects of quantum many-body systems. The dynamics of entanglement has recently been studied in the context of measurement-induced entanglement transitions, where the steady-state entanglement collapses from a volume-law to an area-law at a critical measurement probability $p_{c}$. Interestingly, there is a distinction in the value of $p_{c}$ depending on how well the underlying unitary dynamics scramble quantum information. For strongly chaotic systems, $p_{c} > 0$, whereas for weakly chaotic systems, such as integrable models, $p_{c} = 0$. In this work, we investigate these measurement-induced entanglement transitions in a system where the underlying unitary dynamics are many-body localized (MBL). We demonstrate that the emergent integrability in an MBL system implies a qualitative difference in the nature of the measurement-induced transition depending on the measurement basis, with $p_{c} > 0$ when the measurement basis is scrambled and $p_{c} = 0$ when it is not. This feature is not found in Haar-random circuit models, where all local operators are scrambled in time. When the transition occurs at $p_{c} > 0$, we use finite-size scaling to obtain the critical exponent $ν= 1.3(2)$, close to the value for 2+0D percolation. We also find a dynamical critical exponent of $z = 0.98(4)$ and logarithmic scaling of the Rényi entropies at criticality, suggesting an underlying conformal symmetry at the critical point. This work further demonstrates how the nature of the measurement-induced entanglement transition depends on the scrambling nature of the underlying unitary dynamics. This leads to further questions on the control and simulation of entangled quantum states by measurements in open quantum systems.

description: The ongoing COVID-19 pandemic has affected most of the countries on Earth. It has become a pandemic outbreak with more than 24 million confirmed infections and above 840 thousand deaths worldwide. In this study, we consider a mathematical model on COVID-19 transmission with the prosocial awareness effect. The proposed model can have four equilibrium states based on different parametric conditions. The local and global stability conditions for awareness free, disease-free equilibrium is studied. Using Lyapunov function theory and LaSalle Invariance Principle, the disease-free equilibrium is shown globally asymptotically stable under some parametric constraints. The existence of unique awareness free, endemic equilibrium and unique endemic equilibrium is presented. We calibrate our proposed model parameters to fit daily cases and deaths from Colombia. Sensitivity analysis indicates that the transmission rate and learning factor related to awareness of susceptibles are very crucial for reduction in disease related deaths. Finally, we assess the impact of prosocial awareness during the outbreak and compare this strategy with popular control measures. Results indicate that prosocial awareness has competitive potential to flatten the curve.

Evolutionary population synthesis: models, analysis of the ingredients and application to high-z galaxies
Creators: name: Maraston, Claudia
Publisher: name: arXiv

Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Evolutionary population synthesis models for a wide range of metallicities, ages, star formation histories, and Horizontal Branch morphologies, including blue morphologies at high metallicity, are computed. The energetics of the post Main Sequence evolutionary phases are evaluated with the fuel consumption theorem. The impact on the models of the stellar evolutionary tracks is assessed. We find modest differences in synthetic broad-band colours as induced by the use of different tracks in our code (e.g. d(V-K) ~ 0.08 mag; d(B-V) ~ 0.03 mag). These differences are smaller than the scatter among other models in the literature, even when the latter adopt the same evolutionary tracks. The models are calibrated with globular cluster data from the Milky Way for old ages, and the Magellanic Clouds plus the merger remnant galaxy NGC 7252, for ages of ~ 0.1 - 2 Gyr, in a large wavelength range from U to K. Particular emphasis is put on the contribution from the Thermally-Pulsing Asymptotic Giant Branch phase. We show that this phase is crucial for the modelling of young stellar populations by the comparison with observed spectral energy distributions of Magellanic Clouds clusters, which are characterised by high fluxes both blueward and redward the V-band. We find that the combination of the near-IR spectral indices C2 and H2O can be used to determine the metallicity of ~ 1 Gyr stellar populations. We re-analyze the spectral energy distributions of some of the high-z galaxies (2.4 < z < 2.9) observed with the Spitzer Space Telescope by Yan et al. (2004). Their high rest-frame near-IR fluxes are reproduced very well with the models including Thermally-Pulsing Asymptotic Giant Branch stars for ages in the range 0.6-1.5 Gyr, suggesting formation redshifts around z ~ 3-6.

description: This paper examines the criticism of contingent valuation put forth by Blamey, Common and Quiggin (Australian Journal of Agricultural and Resource Economics, 1995, vol. 39, pp. 264–288). They argue that households have consistent preferences over private goods but not jointly consistent preferences over public and private goods and, hence, contingent valuation cannot uncover meaningful responses for the valuation of public goods. In this paper we argue that the motives that are manifested in choices for public goods can be explained in two ways. One is the model of the citizen, proposed by Blamey et al. (1995). The second is a model of neoclassical preferences with altruism. Given these alternative and competing explanations of choices for public goods, what matters is whether they imply differences in willingness to pay for public goods. We provide statistical evidence from a contingent valuation study of the control of deer in the USA that there is no difference in willingness to pay between those who profess ‘citizen’ or altruistic preferences and the rest of the presumably purely private respondents.

description: In recent decades, non‐farm employment has become prevalent and an important source of income for Australian farm families. However, models identifying the relative significance of the socioeconomic variables influencing non‐farm employment participation rates have never been estimated in Australia. In this paper, a bivariate probit model of non‐farm employment participation rates was estimated, using information from the Australian Bureau of Agricultural Resource Economics (ABARE) 1994–1995 surveys. It was found that the participation decision of the farm operator and spouse is likely to be jointly determined, that non‐farm employment participation increased at a declining rate with age among farmers and that university education enhances the participation rates particularly among spouses. Participation rates were also higher among spouses with lower other income and with no dependent children.

We propose using a Bidirectional Lattice Recurrent Neural Network (LatticeRNN) for the task, and show that it can significantly improve detection accuracy over using the 1-best result or the posterior.

Exploring the influence of school and community relationships on the performance of aboriginal students in British Columbia public schools
Creators: name: Aman, Cheryl Lynn
Publisher: name: University of British Columbia
Year: 2010

description: The objective of the research was to determine how the dynamics of school and community context interact with school completion of Aboriginal students in the province of British Columbia, Canada. A large-scale exploratory analysis of secondary data was conducted. Data were derived from approximately 1.5 million school records of students enrolled in all public schools province-wide over thirteen years of time. The variability of school completion of Aboriginal students across time and across schools was a central research interest. Findings are presented at both the student and the school-level. On-Reserve Status Indian students and highly mobile Aboriginal students emerged as subpopulations of Aboriginal students with significantly low school-completion rates. A hierarchical linear model (HLM) of interactions of Band status, student migration, socioeconomic factors and non-Aboriginal graduation rates with school completion rates of Aboriginal students is presented. Implications are discussed in terms of education policy at the school, school district and provincial level. As well, issues associated with collecting, interpreting and reporting data pertaining to Aboriginal school outcomes are discussed.

description: It is shown that production of low-mass $e^+e^-$-pairs in ultraperipheral nuclear collisions is enhanced due to the Sommerfeld-Gamow-Sakharov (SGS) factor. This effect is especially strong near the threshold of creation of unbound $e^+e^-$-pairs with low masses in the two-photon fusion. Coulomb attraction of the non-relativistic components of such pairs may lead to the increased intensity of 511 keV photons. It can be recorded at the NICA collider and has some astrophysical implications. The analogous effect can be observed at LHC in dilepton production.

description: Although a relatively small producer, Australia exports more than 90 per cent of its cotton production, making it the world's third largest cotton exporter in recent years. This means that export performance plays a major role in determining the profitability of the Australian cotton industry. The primary aim of this study was to determine the competitive position of Australian cotton in the Japanese market, based on the original non‐linear Almost Ideal Demand System model using data from 1972 to 1998. The main findings are that the USA had a relatively strong market position and that Australia needs to improve its cost competitiveness and quality image to advance its market standing.

description: With presently known input physics and computer simulations in 1D, a self-consistent treatment of core collapse supernovae does not yet lead to successful explosions, while 2D models show some promise. Thus, there are strong indications that the delayed neutrino mechanism works combined with a multi-D convection treatment for unstable layers. On the other hand there is a need to provide correct nucleosynthesis abundances for the progressing field of galactic evolution and observations of low metallicity stars. The innermost ejecta is directly affected by the explosion mechanism, i.e. most strongly the yields of Fe-group nuclei for which an induced piston or thermal bomb treatment will not provide the correct yields because the effect of neutrino interactions is not included. We apply parameterized variations to the neutrino scattering cross sections and alternatively, parameterized variations are applied to the neutrino absorption cross sections on nucleons in the ``gain region''. We find that both measures lead to similar results, causing explosions and a Ye>0.5 in the innermost ejected layers, due to the combined effect of a short weak interaction time scale and a negligible electron degeneracy, unveiling the proton-neutron mass difference. We include all weak interactions (electron and positron capture, beta-decay, neutrino and antineutrino capture on nuclei, and neutrino and antineutrino capture on nucleons) and present first nucleosynthesis results for these innermost ejected layers to discuss how they improve predictions for Fe-group nuclei. The proton-rich environment results in enhanced abundances of 45Sc, 49Ti, and 64Zn as requested by chemical evolution studies and observations of low metallicity stars as well as appreciable production of nuclei in the mass range up to A=80.

We also consider the case of contact-symplectic and contact-contact structures, in which the constant class condition on a one-form is replaced by the condition that its kernel hyperplane distribution have constant class in the sense of E. Cartan.

description: We consider here, a two-atom system is uniformly moving through a circular ring at an ultra-relativistic speed and weakly interacting with common external fields. The vacuum fluctuations of the quantum fields generate the entanglement between the atoms. Hence an effective energy shift is originated, which depends on the inter-atomic distance. This is commonly known as resonance Casimir-Polder interaction (RCPI). It is well known that, for a linearly accelerated system coupled with a massless scalar field, we get a thermal response when the local inertial approximation is valid. On the contrary, the non-thermality arises in the presence of the centripetal acceleration. We use the quantum master equation formalism to calculate the second-order energy shift of the entangled states in the presence of two kinds of fields. They are the massive free scalar field and the electromagnetic vector field. For both cases, we observe the non-thermal behavior. A unique retarded response is also noticed in comparison to the free massless case, which can be observed via the polarization transfer technique.

description: The aim of this paper is to set constraints of the epochs of early-type galaxy formation through the 'archaeology' of the stellar populations in local galaxies. Using our models of absorption line indices that account for variable abundance ratios, we derive the stellar population parameters of 124 early-type galaxies in high and low density environments. We find that all three parameters age, metallicity, and alpha/Fe ratio are correlated with velocity dispersion. We further find evidence for an influence of the environment on the stellar population properties. Massive early-type galaxies in low-density environments appear on average ~2 Gyrs younger and slightly more metal-rich than their counterparts in high density environments. No offsets in the alpha/Fe ratios, instead, are detected. We translate the derived ages and alpha/Fe ratios into star formation histories. We show that most star formation activity in early-type galaxies is expected to have happened between redshifts 3 and 5 in high density and between redshifts 1 and 2 in low density environments. We conclude that at least 50 per cent of the total stellar mass density must have already formed at z 1, in good agreement with observational estimates of the total stellar mass density as a function of redshift. Our results suggest that significant mass growth in the early-type galaxy population below z 1 must be restricted to less massive objects, and a significant increase of the stellar mass density between redshifts 1 and 2 should be present caused mainly by the field galaxy population. The results of this paper further imply vigorous star formation episodes in massive objects at z 2-5 and the presence of evolved ellipticals around z 1, both observationally identified as SCUBA galaxies and EROs.

description: A new structural phase transition has been observed at low temperatures for the one third of a monolayer (alpha phase) of Pb on Ge(111) using a variable-temperature scanning tunneling microscope. The well-known (r3xr3)R30 to (3x3) transition is accompanied by a new structural phase transition from (3x3) to a disordered phase at ~76 K. The formation of the new disordered phase is incompatible with the belief that the (3x3) phase is the ground state. The mechanism of the phase transition in this triangular lattice can be mapped onto antiferromagnetic spin Ising model, with the geometric frustration.

Effects on growth of environmental policy in a small open economy

description: This paper examines the effect of environmental policy on economic growth in a small open economy in a neoclassical framework with pollution as an input. We show that environmental policy imposes a drag on long run growth in both the open and closed economy cases. The effect of environmental policy on growth is stronger in the open economy case relative to the closed economy model if the country has strong aversion to pollution and thus serves as a net exporter of capital in the international capital market. On the other hand, if the agents in the economy have low aversion to pollution and thus import capital, the effect of environmental care on growth is stronger in the closed economy relative to the open economy. Thus, from our set-up, environmental policy is harmful to growth but environmental sustainability need not be incompatible with continued economic growth.

description: The study examined the effects of various trade policy instruments such as tariff, import restrictions, outright ban on rice import and other determinants on the import demand for rice in Nigeria between 1960 and 2007. Adopting a dynamic modeling approach, the unit root test of the series used in the model showed that they are all integrated of order one . Result of the long run equilibrium analysis showed that there is a long run relationship among the variables included in the model as the unit root test of the residual generated from the analysis was stationary at the level. Also, in the long run equilibrium model, three of the variables; exchange rate, per capita income and local output of rice were statistically significant at alpha 0.05 and all affected rice import demand positively. The short run dynamic model (ECM) result further confirmed the significance of per capita income and local output as major positive determinants of rice import in Nigeria. The significance of the coefficient of the error correction term confirmed the appropriateness of the error correction approach which also showed that ignoring the long run relationship is detrimental. The speed of adjustment measured by the coefficient of the error term indicated 99% instability in the growth rate of rice import in Nigeria during the period under study. Though the responsiveness of import demand for rice was particularly elastic with respect to exchange rate and per capita income, the most effective policy variable that can be focused on in the short run is the local output of the commodity. Thus, at primary production level, efforts should include subsidies of various form at various levels targeted at rice farmers while at secondary production level, efforts should include providing an enabling environment for private sector to invest in rice processing.

description: Metal intercalation into layered topological insulator materials such as the binary chalcogenide Bi2X3 (X=Te or Se) has yielded novel two-dimensional electron-gas physics, phase transitions to superconductivity, as well as interesting magnetic ground states. Of recent interest is the intercalation-driven interplay between lattice distortions, density wave ordering, and the emergence of new phenomena in the vicinity of instabilities induced by intercalation. Here, we examine the effects of Cu-intercalation on the ternary chalcogenide Bi2Te2Se. We report the discovery, in Cu0.3Bi2Te2Se, of a periodic lattice distortion at room temperature, together with a charge density wave transition around Td = 220K. We also report, for the first time, a complete study of the CuxBi2Te2Se system, and the effect of Cu-intercalation on crystal structure, phonon structure, and electronic properties for 0.0 $\le$ x $\le$ 0.5. Our electron diffraction studies reveal strong Bragg spots at reciprocal lattice positions forbidden by ABC stacking, possibly resulting from stacking faults, or a superlattice. The c-axis lattice parameter varies monotonically with x for 0 $\lt$ x $\lt$ 0.2, but drops precipitously for higher x. Similarly, Raman phonon modes $A^2_{1g}$ and $E_g$ soften monotonically for 0 $\lt$ x $\lt$ 0.2 but harden sharply for x $\gt$ 0.2. This indicates that Cu likely intercalates up to x $\sim$0.2, followed by partial site-substitutions at higher values. The resulting strain makes the 0.2 $\lt$ x $\lt$ 0.3 region susceptible to instabilities and distortions. Our results point toward the presence of an incommensurate CDW above Td = 220 K. This work strengthens prevalent thought that intercalation contributes significantly to instabilities in the lattice and charge degrees of freedom in layered chalcogenides.

description: Micro-credit loans assist the poor women in developed countries to help themselves achieve sustainability in entrepreneurial development. However, unavailability and insufficient credit loans are the major impediments to agricultural development and poverty alleviation in underdeveloped and developing countries. This study identified the women farmers’ experiences in having access to micro-credit institutions in Oyo State of Nigeria. The study revealed both institutional and non-institutional micro-credit foundations as sources of credit available to women farmers in the area. Formation of informal micro-credit self-help groups brought more relief and quick services to the women farmers’ problems. The finding revealed that majority of the women farmers received less than the amount of loan requested. The repayment rate was very poor due to the mode of disbursement and inability to utilize the loan efficiently. Some constraints were observed as problems encountered in obtaining loan from NACB. However, there was significant relationship between education (Chi2 = 16.25: p = 0.039), farming experience (Chi2 = 15.86: p = 0.044), farm size (Chi2 = 17.01: p = 0.009) and access to loan. There is need for commitment by micro-credit institutions to providing information and credits in a timely and accurate manner and disburse reasonable credit loan to the women.
