description: The behavior of As in aqueous media in the complex crystalline aquifers like that of the present study area is not yet understood properly. To that end, groundwater and river water samples from two different seasons are analyzed for As and physicochemical parameters. The groundwater in the area is evolved by simple dissolution or mixing of two or more different facies (Ca2+–Mg2+–Na+–SO42–). However, the majority of samples with the base-exchange indices (85%) and meteoric genesis indices (77%) value less than unitary (<1) divulges that Na+– SO42– type water and deeper meteoric percolation. The estimation of As in groundwater (<0.1–202 ppb) shows the spatial and temporal inconsistency with 17.31% (pre-monsoon) and 11.67% (post-monsoon) of the samples surpassed the permissible limit of 10 ppb. Furthermore, health risk associated with As in terms of hazard quotient (HQ) values > 1 (pre-monsoon: 21.15% and post-monsoon: 20%) for children and carcinogenic risk values >1.00 × 10−6 for different seasons (44.25% and 33.33% of samples) represents a serious health risk. Furthermore, the different stages of Keratosis and Melanosis diseases reported in the study area establish the severity of As toxicity on the local populace. The study concludes geogenic arsenic contamination in the study area is primarily associated with Rhyolite and its comagmatically formed Dongargarh granite batholith emplacements.

description: Recently, deuterium has been the focus of a high level of experimental and theoretical activity that was sparked by a disagreement on the experimental value of the maximum compression along the Hugoniot. The behavior of deuterium at Mbar pressures is not well understood. It is of great interest to understand how the current uncertainty on the hydrogen/deuterium EOS affects the inferred structures of Jupiter and Saturn. In particular, the mass of a core of heavy elements (other than H and He) and the total mass of those heavy elements in these two planets are quite sensitive to the EOS of hydrogen and constitute important clues to their formation process. We present a study of the range of structures allowed for Jupiter and Saturn by the current uncertainty in the hydrogen EOS and astrophysical observations of the two planets. An improved experimental understanding of hydrogen at Mbar pressures and better determinations of the gravitational moments of both planets are necessary to put tight bounds on their internal structure.

Το ενδιαφέρον εστιάζεται στις ψυχοκοινωνικές και συναισθηματικές εμπειρίες των γονέων που φροντίζουν ανάπηρα παιδιά και νέους στο πλαίσιο της καθημερινότητάς τους. Η μελέτη υιοθετεί μεθοδολογικά την ποιοτική προσέγγιση και βασίζεται στις ημιδομημένες συνεντεύξεις οκτώ γυναικών - μητέρων. Αναδεικνύουμε, μέσα από την ανάλυση του λόγου τους, τις βιωμένες εμπειρίες και τις αντιλήψεις τους. Η ανάλυση συζητείται και συγκρίνεται με βασικές θέσεις θεωρητικών της αναπηρίας ή άλλων ερευνητών, που στηρίχθηκαν είτε στο ιατρικό είτε στο κοινωνικό μοντέλο της αναπηρίας. Απώτερος στόχος της εν λόγω έρευνας είναι - πέρα από την ανάδειξη της υποκειμενικής εμπειρίας των συμμετεχόντων γονέων, των ταυτοτήτων που συγκροτούν και της φύσης των αλληλεπιδράσεών τους με τους επαγγελματίες - η προοπτική μιας εκ νέου εννοιολόγησης της γονεϊκής εμπειρίας με βάση τη διαλεκτική σχέση του ψυχολογικού με το κοινωνικό μοντέλο της αναπηρίας.
description: The present study investigates the topic "Family & Disability" in the light of how parental identities are formed and the cooperative relationships between parents of disabled children and professionals. The focus is on the psychosocial and emotional experiences of parents caring for disabled children and young people in their daily lives. The study methodologically adopts the qualitative approach and is based on the semi-structured interviews of eight women and mothers. Through the analysis of the participants’ interviews, we focus on their lived experiences and perceptions. The analysis is discussed and compared with key positions of disability theorists or other researchers, based on either the medical or social model of disability. The goal of the present research is mainly focused on the construction of parents’ diverse identities during their collaboration with professionals from the educational and the medical setting. The study suggests the re-conceptualization of parenting experience based on the dialectical relationship of the psychological aspect and the social model of disability.

description: Pretomanid (PA-824) is the recently (2019) approved drug for the treatment of extensively drug-resistant (XDR) TB and the multidrug-resistant (MDR) TB by US FDA. The experimental data of antitubercular activity of 543 pretomanid derivatives (total 6 datasets) against replicating (active) and non-replicating (dormant) forms of Mycobacterium tuberculosis (strain H37Rv) are available in the literature. Such vast experimental data of pretomanid derivatives against both of these endpoints, and recent approval of pretomanid molecule as a drug encouraged us to utilize this existing experimental information for the development of the 3D-pharmacophore models. The developed model (Hypo-1, MABA) showed the three physicochemical features namely, the oxygen atom of nitro group (HBA_1), fused pyran ring of imidazopyran heterocycle (HYAl_2) and the 4-fluorophenyl moiety (HYAr_3) are crucial for the antitubercular activity against replicating M. tb. Subsequently, the pharmacophore model (Hypo-1, LORA) developed against the non-replicating form of M. tb also showed the contribution of three physicochemical features namely, the 4-tri-fluoromethyl group (HYAl_2) and both the phenyl groups (HYAr_3, HYAr_4) of biaryl moiety in increasing the antitubercular activity. Both the pharmacophoric classifier models showed the classification accuracies of 82.98 and 74.42% for the training set compounds, and 63.91 and 61.60% for the test set compounds respectively, for labelling the compounds into higher and lower active classes. Both the models were also found to be retaining the higher active compounds in top 1.00% of the total number of compounds (decoys and actives), after performing the decoy set screening.
The art and soul of home economics
Creators: name: DeLeeuw, Tara
Publisher: name: The University of British Columbia
Year: 2023

description: This paper explores the connection between art and home economics and how an emphasis on art might bring about more soulfulness to education in general and home economics in particular. My exploration of art is two-fold. One approach is to recognize and build upon the artful nature inherent within home economics (being one of the practical arts) by helping students engage their creativity and imagination, which in itself is nourishing to the soul and leads to the development of soulful attributes. The second is in the viewing and discussing of art as a pedagogical practice to bring forth soulful concepts that can be present within our classroom. A soulful classroom is characterized by a sense of connection and community among its students, where creativity is supported and fostered, where attention is given to the sacred nature of everyday life and where social justice and emancipatory action are revealed and where intimacy, empathy and the conscientious use of resources are experienced.

description: We have used modern supercomputer facilities to carry out extensive numerical simulations of statistical properties of 1D and 2D arrays of single-electron islands with random background charges, in the limit of small island self-capacitance. In particular, the spectrum of single-electron addition energies shows a clear Coulomb gap that, in 2D arrays, obeys the Efros-Shklovskii theory modified for the specific electron-electron interaction law. The Coulomb blockade threshold voltage statistics for 1D arrays is very broad, with r.m.s. width $δV_t$ growing as $ \propto N^{1/2}$ with the array size $N$. On the contrary, in square 2D arrays of large size the distribution around $ \propto N$ becomes relatively narrow $(δV_t/< V_t> \propto 1/N)$, and the dc $I$-$V$ curves are virtually universal. At low voltages, the slope $G_0(T)$ of $I$-$V$ curves obeys the Arrhenius law. The corresponding activation energy $U_0$ grows only slowly with $N$ and is considerably lower than the formally calculated "lowest pass" energy $E_{max}$ of the potential profile, thus indicating the profile "softness".

Both temporal (discrete-time) evolutions and spatial (along the lattice at a constant time-level) evolutions are considered. In the classical limit, the temporal equations reduce to the (classical) discrete Dubrovin equations as given in a previous publication. The reconstruction of the original dynamical variables in terms of the Sklyanin variables is also achieved.

description: The objective of this dissertation is the pathological development and termination of the franchising contract. In particular, the aspects being analyzed are all the ways of termination of the franchise agreement, the consequences of its termination, the obligations of the parties after the termination of the contract, the protection of any investments made by the franchisee prior to the termination of the contract, which could not be recuperated until its termination, the possibility of claiming customer compensation of the franchisee by the proportional application of Article 9 of p.d. 219/1991 and the post-contractual prohibition of competition. For a better understanding, prior to the analysis of the above issues, it is advisable to take a brief conceptual approach to the franchise agreement, referring to its legislative regulation, legal nature and characteristics, various forms and presence in international trade.

description: Myoglobin (Mb), oxygen-binding heme-protein retrieved primarily in muscles, is a local oxygen reservoir providing to oxygen when oxygen delivery is insufficient during catabolism. Furthermore, Mb structure is studied as example of molecular evolution for its ability to respond to environmental pressures and adapt to it through few amino acid substitutions. Here, in order to explore the structure-function-dynamics relationships of Eurasian woodcock chicken and ostrich Mbs we have applied an integrated approach in which spectroscopic and biochemical data have been coupled to computational techniques as structural modelling and molecular dynamics simulations. The primary structure of E. woodcock Mb, reveals the presence of three (i.e. Q34H, E44D and V66A) and ten (i.e. A19T, E27A, V28I, K50T, D53E, G57A, D60E, N81K, S84A and A120S) amino acid substitutions respect to chicken and ostrich Mbs, respectively. Although the high amino acid sequence identity, E. woodcock Mb display a higher autoxidation rate than chicken and ostrich Mb despite of a similar melting temperature (Tm ∼ 358 K). Yet, the 3D structural models validated by using experimental data indicate that the three Mbs adopt an almost identical three-dimensional structure conserving the typical secondary and tertiary structural organization. Interestingly, dynamics data reveal that the E. woodcock myoglobin exhibits greater internal motions than either chicken or ostrich Mbs. Overall, our study demonstrates that in Mbs the functional properties are significantly driven by the protein dynamic peculiarities, which in turn depend on the amino acid composition of the region located in proximity of the pathways for the gas ligands.

description: The asymptotics of characters $χ_{kλ}(\exp(h/k))$ of irreducible representations of a compact Lie group $G$ for large values of the scaling factor $k$ are given by Duistermaat-Heckman (DH) integrals over coadjoint orbits of $G$. This phenomenon generalises to coadjoint orbits of central extensions of loop groups $\widehat{LG}$ and of diffeomorphisms of the circle $\widehat{\rm Diff}(S^1)$. We show that the asymptotics of characters of integrable modules of affine Kac-Moody algebras and of the Virasoro algebra factorize into a divergent contribution of the standard form and a convergent contribution which can be interpreted as a formal DH orbital integral. For some Virasoro modules, our results match the formal DH integrals recently computed by Stanford and Witten. In this case, the $k$-scaling has the same origin as the one which gives rise to classical conformal blocks. Furthermore, we consider reduced spaces of Virasoro coadjoint orbits and we suggest a new invariant which replaces symplectic volume in the infinite dimensional situation. We also consider other modules of the Virasoro algebra (in particular, the modules corresponding to minimal models) and we obtain DH-type expressions which do not correspond to any Virasoro coadjoint orbits. We study volume functions $V(x)$ corresponding to formal DH integrals over coadjoint orbits of the Virasoro algebra. We show that they are related by the Hankel transform to spectral densities $ρ(E)$ recently studied by Saad, Shenker and Stanford.

description: We present a density functional theory (DFT) calculation in the generalized gradient approximation to study the possibility for the existence of Jahn-Teller (JT) or pseudo Jahn-Teller (PJT) type local distortions in the La-Ba-Cu-O superconducting system. We performed the calculation and correspondingly group theory classification of the electronic ground state of the CuO${_{6}}^{-10}$ elongated octahedra cluster, immersed in a background simulating the superconductor. Part of the motivation to do this study is that the origin of the apical deformation of the CuO${_{6}}^{-10}$ cluster is not due to a pure JT effect, having therefore a non {\it a priori} condition to remove the degeneracy of the electronic ground state of the parent regular octahedron. We present a comparative analysis of the symmetry classified electron spectrum with previously reported results using unrestricted Hartree-Fock calculations (UHF). Both the DFT and UHF calculations produced a non degenerate electronic ground state, not having therefore the necessary condition for a pure JT effect. However, the appearance of a degenerate E$_{g}$ state near to the highest occupied molecular orbital in the DFT calculation, suggests the possibility for a PJT effect responsible for a local distortion of the oxidized CuO$_{6}^{-9}$ cluster.

description: The goal of this study was to evaluate the age-differentiated health risks associated with exposure to mercury in drinking water from artisanal small-scale gold mining (ASGM) sites on nearby communities in Yolombo, Colombia. In 2017, nine samples were collected from a local regulatory agency to report mercury concentrations in locations near mining sites. We performed a risk assessment to find 100% of the water samples collected downstream of mining sites exceed Hazard Quotient (HQ) risk thresholds (set by the US-Environmental Protection Agency and Health Canada). HQ model, coupled with global sensitivity and uncertainty analysis (GSUA), was used to conclude infants as the most vulnerable, with 50% of the population exceeding HQ thresholds. Length of exposure was the most significant input that contributed to risk variance, explaining 30-55% of risk across all age groups. Monte-Carlo filtering was used to identify effective strategies to reduce the number of individuals exceeding allowable HQ thresholds. After Monte-Carlo filtering intervention strategies, all individuals are below HQ thresholds. This work shows the importance of combining risk assessment tools with sensor data to inform the need for filters, stakeholder education, and alternative mining approaches to gain a multi-perspective risk approach. This work provides a valuable risk and decision modeling methodology and baseline information to gain a deeper understanding of the probability of experiencing detrimental health effects from water contamination in ASGM communities.

description: We study the evolution of a small-scale emerging flux region (EFR) in the quiet Sun, from its emergence to its decay. We track processes and phenomena across all atmospheric layers, explore their interrelations and compare our findings with recent numerical modelling studies. We used imaging, spectral and spectropolarimetric observations from space-borne and ground-based instruments. The EFR appears next to the chromospheric network and shows all characteristics predicted by numerical simulations. The total magnetic flux of the EFR exhibits distinct evolutionary phases, namely an initial subtle increase, a fast increase and expansion of the region area, a more gradual increase, and a slow decay. During the initial stages, bright points coalesce, forming clusters of positive- and negative-polarity in a largely bipolar configuration. During the fast expansion, flux tubes make their way to the chromosphere, producing pressure-driven absorption fronts, visible as blueshifted chromospheric features. The connectivity of the quiet-Sun network gradually changes and part of the existing network forms new connections with the EFR. A few minutes after the bipole has reached its maximum magnetic flux, it brightens in soft X-rays forming a coronal bright point, exhibiting episodic brightenings on top of a long smooth increase. These coronal brightenings are also associated with surge-like chromospheric features, which can be attributed to reconnection with adjacent small-scale magnetic fields and the ambient magnetic field. The emergence of magnetic flux even at the smallest scales can be the driver of a series of energetic phenomena visible at various atmospheric heights and temperature regimes. Multi-wavelength observations reveal a wealth of mechanisms which produce diverse observable effects during the different evolutionary stages of these small-scale structures.

description: This study aimed to screen putative drug targets associated with biofilm formation of multidrug-resistant Acinetobacter baumannii and Pseudomonas areugenosa and prioritize carbon nano-fullerene as potential lead molecule by structure-based virtual screening. Based on the functional role, 36 and 83 genes that are involved in biofilm formation of A. baumannii and P. areugenosa respectively were selected and metabolic network was computationally constructed. The genes that lack three-dimensional structures were predicted and validated. Carbon nano-fullerene selected as lead molecule and their drug-likeliness and pharmacokinetics properties were computationally predicted. The binding potential of carbon nano-fullerene towards selected drug targets was modeled and compared with the binding of conventional drugs, doripenem, and polymyxin-B with their usual targets. The stabilities of four best-docked complexes were confirmed by molecular dynamic (MD) simulation. This study suggested that selected genes demonstrated relevant interactions in the constructed metabolic pathways. Carbon fullerene exhibited significant binding abilities to most of the prioritized targets in comparison with the binding of last-resort antibiotics and their usual target. The four best ligand-receptor interactions predicted by molecular docking revealed that stability throughout MD simulation. Notably, carbon fullerene exhibited profound binding with outer membrane protein (OmpA) and ribonuclease-HII (rnhB) of A. baumannii and 2-heptyl-4(1H)-quinolone synthase (pqsBC) and chemotaxis protein (wspA) of P. aeruginosa. Thus, the current study suggested that carbon fullerene probably used as potential lead molecules towards selected targets of A. baumannii and P. aeruginosa and the applied aspects probably scaled up to design promising lead molecules towards these pathogens.

description: Prior research on Mexican migration has shown that social networks and economic incentives play an important role in determining migration outcomes. This study utilizes experimental data on PROGRESA, Mexico's primary poverty reduction program, to evaluate the effects of public cash transfers on migration. Our study complements a growing body of literature aimed at overcoming longstanding hurdles towards the establishment of causal validity in empirical studies of migration. We find that public cash transfers reduce US migration but have little effect on domestic migration. Furthermore, we find that the provision of cash transfers appears to reduce migration partly by reducing the relative deprivation levels of poor households. Finally, we find that the effect of public cash transfers on US migration depend on the size of existing US migration networks. Surprisingly, we see that transfers have larger (more negative) effects on US migration in communities with large existing networks. The results suggest that public transfers may be helpful in managing rural out-migration, particularly to the US. Interestingly, such programs may be most effective if they are targeted towards communities with strong existing migration patterns.

description: This paper provides an assessment of the agricultural diversification trends in South Asia. In the first part food consumption and crop production patterns in the region during the last twenty years are reviewed. Next, the agronomic and economic options for and constraints to diversification in the main agricultural systems are discussed based on a framework for assessing the flexibility of ricelands and rice farmers to respond to the commercialisation trends through seasonal or permanent diversification out of various farming systems. The principal contribution of this paper is to draw attention to some neglected aspects of diversification, especially the biophysical and economic constraints to the process in different farming systems. The flexibility of farmers in responding to diversification opportunities is constrained by the size of markets and price risks, soil suitability and land rights, the availability and quality of irrigation infrastructure, and the availability and cost of labour. Long term strategies to facilitate a smooth transition to commercialisation are recommended.

Infusing critical thinking in home economics education

description: This paper documents my teacher inquiry action research project, whereby I explored how critical thinking can be infused into home economics. I began with a literature review, identifying the relationship between critical thinking and education then used this information to plan, act, observe and reflect on my teaching practice. This paper documents the ways in which critical thinking was infused into my home economics classes that included setting up the learning environment, using a problem solving approach and modifying existing lessons to incorporate critical thinking teaching strategies. When critical thinking is infused into home economics courses, students have the chance to develop skills, dispositions and habits of mind of a critical thinker and thus be better equipped to face everyday problems in our changing world. I found that by using infusing critical thinking as a method to improve my practice I gained confidence in expanding my practice from a technical instrumental focus to a more critical focus and in doing so I noticed an improvement in student engagement in my classes.

description: The polarization of conduction electron spins due to an electrical current is observed in strained nonmagnetic semiconductors using static and time-resolved Faraday rotation. The density, lifetime, and orientation rate of the electrically-polarized spins are characterized by a combination of optical and electrical methods. In addition, the dynamics of the current-induced spins are investigated by utilizing electrical pulses generated from a photoconductive switch. These results demonstrate the possibility of a spin source for semiconductor spintronic devices without the use of magnetic materials.

description: On farm conservation of crop diversity poses obvious policy challenges in terms of the design of appropriate incentive mechanisms and possible trade-offs between conservation and productivity. This paper compares factors explaining the inter-specific diversity (diversity among species) and infra-specific diversity (diversity among varieties within a species) of cereal crops grown in communities and on individual farms in the northern Ethiopian highlands.

description: Units of complex systems -- such as neurons in the brain or individuals in societies -- must communicate efficiently to function properly: e.g., allowing electrochemical signals to travel quickly among functionally connected neuronal areas in the human brain, or allowing for fast navigation of humans and goods in complex transportation landscapes. The coexistence of different types of relationships among the units, entailing a multilayer represention in which types are considered as networks encoded by layers, plays an important role in the quality of information exchange among them. While altering the structure of such systems -- e.g., by physically adding (or removing) units, connections or layers -- might be costly, coupling the dynamics of subset(s) of layers in a way that reduces the number of redundant diffusion pathways across the multilayer system, can potentially accelerate the overall information flow. To this aim, we introduce a framework for functional reducibility which allow us to enhance transport phenomena in multilayer systems by coupling layers together with respect to dynamics rather than structure. Mathematically, the optimal configuration is obtained by maximizing the deviation of system's entropy from the limit of free and non-interacting layers. Our results provide a transparent procedure to reduce diffusion time and optimize non-compact search processes in empirical multilayer systems, without the cost of altering the underlying structure.

description: To systematically analyze the dynamical implications of the matter content in cosmology, we generalize earlier dynamical systems approaches so that perfect fluids with a general barotropic equation of state can be treated. We focus on locally rotationally symmetric Bianchi type IX and Kantowski-Sachs orthogonal perfect fluid models, since such models exhibit a particularly rich dynamical structure and also illustrate typical features of more general cases. For these models, we recast Einstein's field equations into a regular system on a compact state space, which is the basis for our analysis. We prove that models expand from a singularity and recollapse to a singularity when the perfect fluid satisfies the strong energy condition. When the matter source admits Einstein's static model, we present a comprehensive dynamical description, which includes asymptotic behavior, of models in the neighborhood of the Einstein model; these results make earlier claims about ``homoclinic phenomena and chaos'' highly questionable. We also discuss aspects of the global asymptotic dynamics, in particular, we give criteria for the collapse to a singularity, and we describe when models expand forever to a state of infinite dilution; possible initial and final states are analyzed. Numerical investigations complement the analytical results.
