description: In this work we tackle a kinetic-like model of opinions dynamics in a networked population endued with a quenched plurality and polarization. Additionally, we consider pairwise interactions that are restrictive, which is modeled with a smooth bounded confidence. Our results show the interesting emergence of nonequilibrium hysteresis and heterogeneity-assisted ordering. Such counterintuitive phenomena are robust to different types of network architectures such as random, small-world and scale-free.

description: We study the free energies of heavy quarks calculated from Polyakov loop correlation functions in full 2-flavour QCD using the p4-improved staggered fermion action. A small but finite Baryon number density is included via Taylor expansion of the fermion determinant in the Baryo-chemical potential mu. For temperatures above Tc we extract Debye screening masses from the large distance behaviour of the free energies and compare their mu-dependence to perturbative results.

description: As access to the Internet expands, volunteer managers have the option of using this new technology to manage pools of volunteers online. Online volunteering can appear deceptively simple: post an opening, select a volunteer, and then manage them by e‐mail. However, our evaluation of an active online volunteering service used by more than three hundred organizations and ten thousand potential volunteers indicates that additional planning and management are frequently needed. Through an analysis of two years of quantitative data and interviews with more than forty volunteers and managers, we have extracted suggested practices and programmatic implications for managers in the areas of program design, volunteer selection, training, ongoing operations, and evaluation.

description: We compare theory and experiment in the Casimir force measurement between gold surfaces performed with the atomic force microscope. Both random and systematic experimental errors are found leading to a total absolute error equal to 8.5 pN at 95% confidence. In terms of the relative errors, experimental precision of 1.75% is obtained at the shortest separation of 62 nm at 95% confidence level (at 60% confidence the experimental precision of 1% is confirmed at the shortest separation). An independent determination of the accuracy of the theoretical calculations of the Casimir force and its application to the experimental configuration is carefully made. Special attention is paid to the sample-dependent variations of the optical tabulated data due to the presence of grains, contribution of surface plasmons, and errors introduced by the use of the proximity force theorem. Nonmultiplicative and diffraction-type contributions to the surface roughness corrections are examined. The electric forces due to patch potentials resulting from the polycrystalline nature of the gold films are estimated. The finite size and thermal effects are found to be negligible. The theoretical accuracy of about 1.69% and 1.1% are found at a separation 62 nm and 200 nm, respectively. Within the limits of experimental and theoretical errors very good agreement between experiment and theory is confirmed characterized by the root mean square deviation of about 3.5 pN within all measurement range. The conclusion is made that the Casimir force is stable relative to variations of the sample-dependent optical and electric properties, which opens new opportunities to use the Casimir effect for diagnostic purposes.

description: Black smallholder irrigation schemes should be used as target areas for agricultural development. A number of economic, social and political factors are responsible that the smallholder irrigation schemes in South Africa's Black States are unable to achieve their development potential. The experience of Vuvulane Irrigated Farms in Swaziland proves that Black smallholder schemes can be successfully developed by the application of an integrated development framework. Such a framework incorporates three planning stages, namely the determination of the agricultural potential and the economic profitability of the scheme, and the establishment of the required agricultural infrastructure. The framework aims at providing smallholders with the means and motives to achieve commercial production. As the developer provides the full range of required irrigation services the risk attached to commercial production is largely minimized for the smallholder. By adopting a commercial approach in the provision of the services the developer ensures that the equity objectives of both parties are met and the active participation of smallholders encouraged.

description: Building Information Modelling (BIM) has been applied to various aspects of construction processes in developed countries but Nigeria is yet to realize the full potentials of BIM. It has greater relevance for the commercial and public subsectors as it enhances construction productivity. This study examines current state of BIM in the Nigerian construction industry. The study adopted quantitative research approach by eliciting primary data through questionnaire which was administered to 150 respondents, of which 90 were returned and considered valid for further analysis. The data were analysed using mean item score and correlation. It was revealed that BIM awareness level is only high at the design stage of a building life cycle while it is extremely low at the construction and facility management stages. Also, the commonly used BIM compliant software packages in the Nigerian construction industry were identified to be: Autodesk Quantity Takeoff, Revit Architecture, and SketchUp. The study however recommends that: stakeholders of the construction industry should be educated on how to use BIM complaint software packages throughout the life cycle of a building and its benefits; Government should invest heavily on BIM related research so as to enhance the body of knowledge of BIM in Nigeria and develop a suitable framework for BIM implementation; federal Government should enact policies that will encourage the implementation of BIM in Nigeria.

description: Chromitites (>80% volume chromite) hosted in two ultramafic bodies (Lavanderos and Centinela Bajo) from the Palaeozoic metamorphic basement of the Chilean Coastal Cordillera were studied in terms of their chromite composition, platinumgroup element (PGE) abundances, and Re-Os isotopic systematics. Primary chromite (Cr# = 0.64–0.66; Mg# = 48.71– 51.81) is only preserved in some massive chromitites from the Centinela Bajo ultramafic body. This chemical fingerprint is similar to other high-Cr chromitites from ophiolite complexes, suggesting that they crystallized from arc-type melt similar to high-Mg island-arc tholeiites (IAT) and boninites in supra-subduction mantle. The chromitites display enrichment in IPGE (Os, Ir, Ru) over PPGE (Rh, Pt, Pd), with PGE concentrations between 180 and 347 ppb, as is typical of chromitites hosted in the mantle of supra-subduction zone (SSZ) ophiolites. Laurite (RuS2)-erlichmanite (OsS2) phases are the most abundant inclusions of platinum-group minerals (PGM) in chromite, indicating crystallization from S-undersaturated melts in the subarc mantle. The metamorphism associated with the emplacement of the ultramafic bodies in the La Cabaña has been determined to be ca. 300 Ma, based on K-Ar dating of fuchsite. Initial 187Os/188Os ratios for four chromitite samples, calculated for this age, range from 0.1248 to 0.1271. These isotopic compositions are well within the range of chromitites hosted in the mantle section of other Phanaerozoic ophiolites. Collectively, these mineralogical and geochemical features are interpreted in terms of chromite crystallization in dunite channels beneath a spreading centre that opened a marginal basin above a supra-subduction zone. This implies that chromitite-bearing serpentinites in the metamorphic basement of the Coastal Cordillera are of oceanic-mantle origin and not oceanic crust as previously suggested. We suggest that old subcontinental mantle underlying the hypothetical Chilenia micro-continent was unroofed and later altered during the opening of the marginal basin. This defined the compositional and structural framework in which the protoliths of the meta-igneous and meta-sedimentary rocks of the Eastern and Western Series of the Chilean Coastal Cordillera basement were formed.

The student conference : A model of authenic assessment
Creators: name: Larkin, Teresa
Publisher: name: American University
Year: 2023

description: In the global marketplace, the ability to communicate, both orally and in writing, is a skillset demanded by employers. Unfortunately, typical academic exercises that involve written and oral communication are often just that academic exercises. To provide a more authentic and robust experience, a student conference activity has been developed for use in a second-level physics course entitled Physics for a New Millennium (PNM) at American University (AU). This activity involves writing a formal research paper using professional guidelines. In addition, students present their research paper during a class event modeled after an actual professional conference. A focus of this paper is to discuss the assessment strategies developed for the conference paper activity. A major goal of the assessment strategies designed for the conference paper and the associated presentation is to better capture (and then assess) what students are actually learning in the course. This paper will provide an overview of the student conference paper activity with emphasis on its value as an alternative assessment tool. To that end, a synopsis of how the conference paper activity has been designed will be shared. This synopsis will begin with a general discussion of assessment, assessment methods, and the language of assessment. Following this synopsis a model of non-traditional assessment using the student conference paper will be highlighted. Subsequently a description of the course curriculum and the specific structure for the writing activity will be outlined as they relate to the learning outcomes for the course. Shadowing the presentation of the course-specific learning outcomes, a description of the strategies used to uncover student learning will be shared. These strategies provide an opportunity for multiple assessment â??snapshotsâ? to be made throughout various phases of the learning process. To illustrate these snapshots, examples from actual student work will be presented and discussed. The assessment strategies developed for the student conference paper can be used as an alternative, or as a supplement, to more traditional pencil and paper examinations, quizzes, and homework assignments. Whether used as a stand-alone assessment tool or coupled with more traditional measures, the model presented here can provide an enhanced and more authentic way to capture what students are actually learning while the learning is taking place.

description: Plants have always had a therapeutic effect on humans since time in memorial. Not only do plants serve as a great source of nourishment, clothing, and building material, but they also improve our living environments, our health, and mental well being by providing cleaner air and an aura of aesthetic beauty. Dating back to the time of the Ancient Babylonians the concept of the bio-wall has been used to display the beauty of plants in social infrastructural settings. The architectural excellence of the Hanging Gardens of Babylon has deemed it as one of the seven ancient wonders of the world. In the 1920s, the integration of the house with the garden or man with nature was promoted by a strong garden city movement in Britain and North America. It is in this same spirit that the construction and display of a bio-wall is being proposed as potential means of inspiring students and visitors of the new Student Union building (SUB). Bearing in mind the aim of the new SUB committee to promote sustainability awareness on campus, this proposal of a bio-wall seeks to address this goal directly by providing a functional art piece which is socially attractive and educative on matters of sustainability. In order to investigate the feasibility of the proposal, it is necessary that an effective triple bottom line assessment be conducted to evaluate the environmental, social, and economic factors that pertain to the bio-wall. The evaluation seeks not only to present the benefits in these different areas, but also to present some of the shortfalls that come with the bio-wall’s many advantages. The assessment provides the essential details and information needed to determine the feasibility of the proposal. Overall the analysis supports the implementation of this proposal because of the outstanding impact it will have on bolstering the awareness of sustainability on campus and on improving the experience of students and visitors of the new SUB. Socially the aesthetic value of the bio-wall will attract many viewers and the environmental impact of an improved air quality will also be a social and economic benefit. In addition the aim of this proposal and project is to spark an interest in incorporating bio-wall designs and other vertical wall designs in campus infrastructure and beyond.

description: The critical behavior of $d$-dimensional systems with $n$-component order parameter $\bmϕ$ is studied at an $m$-axial Lifshitz point where a wave-vector instability occurs in an $m$-dimensional subspace ${\mathbb R}^m$ ($m{>}1$). Field theoretic renormalization group techniques are exploited to examine the effects of terms in the Hamiltonian that break the rotational symmetry of the Euclidean group ${\mathbb E}(m)$. The framework for considering general operators of second order in $\bmϕ$ and fourth order in the derivatives $\partial_α$ with respect to the Cartesian coordinates $x_α$ of ${\mathbb R}^m$ is presented. For the specific case of systems with cubic anisotropy, the effects of having an additional term, $\sum_{α=1}^m(\partial_α^2\bmϕ)^2$, are investigated in an $ε$ expansion about the upper critical dimension $d^{*}(m)=4+m/2$. Its associated crossover exponent is computed to order $ε^2$ and found to be positive, so that it is a \emph{relevant} perturbation on a model isotropic in ${\mathbb R}^m$.

description: Aims. The derivation of spectroscopic parameters for M dwarf stars is very important in the fields of stellar and exoplanet characterization. The goal of this work is the creation of an automatic computational tool, able to derive quickly and reliably the T$_{\mathrm{eff}}$ and [Fe/H] of M dwarfs by using their optical spectra, that can be obtained by different spectrographs with different resolutions. Methods. ODUSSEAS (Observing Dwarfs Using Stellar Spectroscopic Energy-Absorption Shapes) is based on the measurement of the pseudo equivalent widths for more than 4000 stellar absorption lines and on the use of the machine learning Python package "scikit-learn" for predicting the stellar parameters. Results. We show that our tool is able to derive parameters accurately and with high precision, having precision errors of ~30 K for T$_{\mathrm{eff}}$ and ~0.04 dex for [Fe/H]. The results are consistent for spectra with resolutions between 48000 and 115000 and SNR above 20.

description: A first-principles theory of resonant magnetic scattering of x rays is presented. The scattering amplitudes are calculated using a standard time-dependent perturbation theory to second order in the electron-photon interaction vertex. In order to calculate the cross section reliably an accurate description of the electronic states in the material under investigation is required and this is provided by the density functional theory (DFT) employing the Local Spin Density Approximation combined with the self-interaction corrections (SIC-LSD). The magnetic x-ray resonant scattering (MXRS) theory has been implemented in the framework of the relativistic spin-polarized LMTO-ASA band structure calculation method. The theory is illustrated with an application to ferromagnetic praseodymium. It is shown that the theory quantitatively reproduces the dependence on the spin and orbital magnetic moments originally predicted qualitatively (Blume, J. Appl. Phys, {\bf 57}, 3615 (1985)) and yields results that can be compared directly with experiment.

description: We discuss the footprint of evaporation of primordial black holes (PBHs) on stochastic gravitational waves (GWs) induced by scalar perturbations. We consider the case where PBHs once dominated the Universe but eventually evaporated before the big bang nucleosynthesis. The reheating through the PBH evaporation could end with a sudden change in the equation of state of the Universe compared to the conventional reheating caused by particle decay. We show that this "sudden reheating" by the PBH evaporation enhances the induced GWs, whose amount depends on the length of the PBH-dominated era and the width of the PBH mass function. We explore the possibility to constrain the primordial abundance of the evaporating PBHs by observing the induced GWs. We find that the abundance parameter $β\gtrsim 10^{-5} \text{ - }10^{-8}$ for $\mathcal{O}(10^3 \text{ - } 10^5) \, \text{g}$ PBHs can be constrained by future GW observations if the width of the mass function is smaller than about a hundredth of the mass.

description: Motivated by the recent suggestion of anisotropic effective exchange interactions between Mn spins in Ga$_{1-x}$Mn$_x$As (arising as a result of spin-orbit coupling), we study their effects in diluted Heisenberg spin systems. We perform Monte Carlo simulations on several phenomenological model spin Hamiltonians, and investigate the extent to which frustration induced by anisotropic exchanges can reduce the low temperature magnetization in these models and the interplay of this effect with disorder in the exchange. In a model with low coordination number and purely ferromagnetic (FM) exchanges, we find that the low temperature magnetization is gradually reduced as exchange anisotropy is turned on. However, as the connectivity of the model is increased, the effect of small-to-moderate anisotropy is suppressed, and the magnetization regains its maximum saturation value at low temperatures unless the distribution of exchanges is very wide. To obtain significant suppression of the low temperature magnetization in a model with high connectivity, as is found for long-range interactions, we find it necessary to have both ferromagnetic and antiferromagnetic (AFM) exchanges (e.g. as in the RKKY interaction). This implies that disorder in the sign of the exchange interaction is much more effective in suppressing magnetization at low temperatures than exchange anisotropy.

description: The development and advancement of prostate cancer (PCa) into stage 4, where it metastasize, is a major problem mostly in elder males. The growth of PCa cells is stirred up by androgens and androgen receptor (AR). Therefore, therapeutic strategies such as blocking androgens synthesis and inhibiting AR binding have been explored in recent years. However, recently approved drugs (or in clinical phase) failed in improving the ex?pected survival rates for this metastatic-castration resistant prostate cancer (mCRPC) patients. The selective CYP17A1 inhibition of 17,20-lyase route has emerged as a novel strategy. Such inhibition blocks the production of androgens everywhere they are found in the body. In this work, a three dimensional-quantitative structure activity relationship (3D-QSAR) pharmacophore model is developed on a diverse set of non-steroidal inhibitors of CYP17A1 enzyme. Highly active compounds are selected to define a six-point pharmacophore hypothesis with a unique geometrical arrangement fitting the following description: two hydrogen bond acceptors (A), two hydrogen bond donors (D) and two aromatic rings (R). The QSAR model showed adequate predictive statistics. The 3D-QSAR model is further used for database virtual screening of potential inhibitory hit structures. Density functional theory (DFT) optimization provides the electronic properties explaining the reactivity of the hits. Docking simulations discovers hydrogen bonding and hydrophobic interactions as responsible for the binding affinities of hits to the CYP17A1 Protein Data Bank structure. 13 hits from the database search (including five derivatives) are then synthesized in the laboratory as different scaffolds. Ultra high performance liquid chro?matography-tandem mass spectrometry (UHPLC-MS/MS) in vitro experiments reveals three new chemical en?tities (NCEs) with half maximal inhibitory concentration (IC50) values against the lyase route at mid-micromolar range with favorable selectivity to the lyase over the hydroxylase route (one of them with null hydroxylase inhibition). Thus, prospective computational design has enabled the design of potential lead lyase-selective inhibitors for further studies.

description: Based on the background and development of the pastoral complex, it is believed that the pastoral complex is an inevitable trend of the development of modern agriculture and it is the product of agriculture developing to a higher stage following agricultural industrial park, beautiful countryside, characteristic town, and whole area tourism. Combined with many years of planning and design practice of Wuhan Modern Urban Agriculture Planning and Design Institute, this paper summarized ideas of construction and operation of the pastoral complex, and discussed the construction of pastoral complex planning system, in the hope of providing certain reference for planning of pastoral complex in the whole country in the new period. Finally, through the overview of development history and highlight of urban agriculture in Wuhan, it came up with measures and recommendations for development of pastoral complex in Wuhan City.
Using the Internet to mobilize marginalized groups : people with disabilities and digital campaign strategies in the 2016 U.S. presidential election
Creators: name: Trevisan, Filippo
Publisher: name: American University
Year: 2023

description: It is important to understand the implications of online election campaigning for groups that have been marginalized in politics. To this end, this article discusses a focus group study on digital campaigning in the 2016 U.S. presidential election with voters with a wide range of physical, mental, and communication disabilities. Digital campaigns can deepen or curtail opportunities for people with disabilities to be active citizens. Participants in this study had high expectations to learn about the candidates through new media platforms, particularly Google and YouTube. However, the 2016 campaigns seemed to struggle to understand Americans with disabilities as an emerging online constituency. This mismatch between demand and supply in online election communication is discussed with a view to illuminating the sociotechnical foundations of digital campaigning and its effect on political participation among citizens with disabilities. There are important opportunities for digital mobilization and inclusion here, but their realization is dependent on a cultural shift that values people with disabilities as full citizens.

Conformal group with two observer independent scales

description: The Poincaré sector of a recently deformed conformal algebra is proposed to describe, after the identification of the deformation parameter with the Planck length, the symmetries of a new relativistic theory with two observer-independent scales (or DSR theory). Also a new non-commutative space-time is proposed. It is found that momentum space exhibits the same features of the DSR proposals preserving Lorentz invariance in a deformed way. The space-time sector is a generalization of the well known non-commutative $κ$-Minkowski space-time which however does not preserve Lorentz invariance, not even in the deformed sense. It is shown that this behavior could be expected in some attempts to construct DSR theories starting from the Poincaré sector of a deformed symmetry larger than Poincaré symmetry, unless one takes a variable Planck length. It is also shown that the formalism can be useful in analyzing the role of quantum deformations in the ``AdS-CFT correspondence".
