Adult Education First Meeting: From Need to Design
Creators: name: Nikitidis Nikolaos
Publisher: name: figshare
Year: 2020
Subjects: Education

description: It is commonplace that the knowledge gained after some time needs enrichment and actualization. Educational actions that are addressed to adults are essential. The first meeting in adult education is crucial for the educational process. It must, therefore, be planned carefully. The aim of this study is to find the elements that make the first meeting efficient. Books and scientific journals are sought for those elements. The planning proposed is to get acquainted with the participants, to identify needs, expectations and preferred ways of learning and finally to create a learning contract. All these actions must be done with respect to the particularities of participants in a climate that is suitable for learning.

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: We propose two ans$\rm\ddot{a}$tze of lepton mass matrices with four texture zeros, and confront them with current experimental data on neutrino oscillations. The parameter space of each ansatz is carefully explored. We find that both ans$\rm\ddot{a}$tze can accommodate the normal hierarchy of neutrino masses and the bi-large pattern of lepton flavor mixing. Their predictions for the effective mass of the tritium beta decay and that of the neutrinoless double beta decay are too small to be detectable, but leptonic CP violation at the percent level is allowed. Some discussions are also given about the seesaw invariance of the four-zero texture of Dirac and Majorana neutrino mass matrices.

Year: 2015

description: The SEEDS (Social Ecological Economic Development Studies) project is done every year in APSC 261 to study real world sustainability (SEEDS UBC, 2010). With difficulty on controlling temperature of large buildings to satisfy all the occupants, personal heaters are used by some occupants. However, use of personal heaters demands more electricity. An investigation is made to find an optimal radiant carpet personal heater to replace the originally used convection heater. Assessment on choosing the new heater is based on the triple bottom line analysis which looks into economic, social and environmental aspects that it impacts. Our product, Foot Warmer™ saves $45.60 per year compared to the convection heater and it has a payback period of 1.2 years. The heater impacts office workers in a positive way with sustainability awareness. The radiant heater uses 1410 W less than the convection heater and produces 14kg less CO2 emissions in the production stage. The main methods of investigation were conducting a survey, testing Foot Warmer™, and interviewing office workers. Secondary sources such as articles, magazines, and newspaper were used to gather technical data to compare specifications between Foot Warmer™ and the convection heater. Foot Warmer™ is a decent candidate for a more sustainable personal heating system. An insulation layer such as cardboard is recommended to be put between Foot Warmer™ and carpet or wood floors to prevent the floor from cracking or discoloring.

description: Food has become both a pivotal topic in development and a lens through which to integrate and address a range of contemporary global challenges. This review article addresses in particular the interrelationship between food and sustainable, equitable development, arguing that this is fundamentally political. We offer a set of approaches to understanding food politics, each underlain by broader theoretical traditions in power analysis, focused respectively on food interests and incentives; food regimes; food institutions; food innovation systems; food contentions and movements; food discourses, and food socio-natures. Applications of these approaches are then illustrated through a set of problematiques, providing a (selective) overview of some of the major literatures and topics of note in food politics and development. Starting with the role of the state and state-society relations in different forms of food regime, we then consider the role of science and technology (and its discourses) in shaping agricultural and food policy directions before looking in more detail at rural livelihoods in agri-food systems and the politics of inclusive structural transformation. Broadening beyond agri-food systems then brings us to interrogate dominant narratives of nutrition and review literature on the cultural politics of food and eating. A concluding section provides a synthesis across the cases, drawing together the various approaches to power and politics and showing how they might be integrated via an analytical framework which combines plural approaches to describe different pathways of change and intervention, raising critical questions about the overall direction and diversity of these pathways, their distributional effects, and the extent of democratic inclusion in decisions about food pathways. We find this extended ‘4D’ approach helpful in highlighting current food systems inequities and the political options for future food systems change, and conclude by considering how it might be harnessed as part of a future interdisciplinary, engaged research agenda.

description: We investigate supergravity models in which the lightest supersymmetric particle (LSP) is a stable gravitino. We assume that the next-lightest supersymmetric particle (NLSP) freezes out with its thermal relic density before decaying to the gravitino at time t ~ 10^4 s - 10^8 s. In contrast to studies that assume a fixed gravitino relic density, the thermal relic density assumption implies upper, not lower, bounds on superpartner masses, with important implications for particle colliders. We consider slepton, sneutrino, and neutralino NLSPs, and determine what superpartner masses are viable in all of these cases, applying CMB and electromagnetic and hadronic BBN constraints to the leading two- and three-body NLSP decays. Hadronic constraints have been neglected previously, but we find that they provide the most stringent constraints in much of the natural parameter space. We then discuss the collider phenomenology of supergravity with a gravitino LSP. We find that colliders may provide important insights to clarify BBN and the thermal history of the Universe below temperatures around 10 GeV and may even provide precise measurements of the gravitino's mass and couplings.

description: A reduction in the output of productive assets (trees) in some states of the world can expand the span of payoffs of assets; and, improved risk sharing may compensate for the loss of output and support a Pareto superior allocation. Surprisingly, if short sales of assets are not allowed, improved risk sharing that results from the destruction of output does not suffice to induce a Pareto superior allocation.
Dynamics of positive- and negative-mass solitons in optical lattices and inverted traps

description: We study the dynamics of one-dimensional solitons in the attractive and repulsive Bose-Einstein condensates (BECs) loaded into an optical lattice (OL), which is combined with an external parabolic potential. First, we demonstrate analytically that, in the repulsive BEC, where the soliton is of the gap type, its effective mass is \emph{negative}. This gives rise to a prediction for the experiment: such a soliton cannot be not held by the usual parabolic trap, but it can be captured (performing harmonic oscillations) by an anti-trapping inverted parabolic potential. We also study the motion of the soliton a in long system, concluding that, in the cases of both the positive and negative mass, it moves freely, provided that its amplitude is below a certain critical value; above it, the soliton's velocity decreases due to the interaction with the OL. At a late stage, the damped motion becomes chaotic. We also investigate the evolution of a two-soliton pulse in the attractive model. The pulse generates a persistent breather, if its amplitude is not too large; otherwise, fusion into a single fundamental soliton takes place. Collisions between two solitons captured in the parabolic trap or anti-trap are considered too. Depending on their amplitudes and phase difference, the solitons either perform stable oscillations, colliding indefinitely many times, or merge into a single soliton. Effects reported in this work for BECs can also be formulated for optical solitons in nonlinear photonic crystals. In particular, the capture of the negative-mass soliton in the anti-trap implies that a bright optical soliton in a self-defocusing medium with a periodic structure of the refractive index may be stable in an anti-waveguide.

description: In this article we deal with a class of geometric inverse problem for bottom detection by one single measurement on the free surface in water--waves. We found upper and lower bounds for the size of the region enclosed between two different bottoms, in terms of Neumann and/or Dirichlet data on the free surface. Starting from the general water--waves system in bounded domains with side walls, we manage to formulate the problem in terms of the Dirichlet to Neumann operator and thus, as an elliptic problem in a bounded domain with Neumann homogeneous condition on the rigid boundary. Then we study the properties of the Dirichlet to Neumann map and analyze the called method of size estimation.

title: Secondary Headship in the Context of School Autonomy
Creators: name: Gifford, Elizabeth Patricia
Publisher: name: The Open University
Year: 2003

description: The passing of the 1988 Education Reform Act created the context of school autonomy, including on-site management responsibility and accountability for performance. The intention behind this research project was to explore the impact of this move on the nature of secondary headship. The survey of the literature (chapter one), relating to headship both pre and post 1988, suggested four areas for exploration (later refined as research questions): the nature of headship itself; success in headship; expectations of staff, students, parents and governors; and preparation for and support during headship.

 A consideration of the most suitable methods (chapter two) led to the adoption of the case study approach to collect qualitative data that would illuminate understanding of developments in headship. Six heads were interviewed and revisited. Senior staff were interviewed and documents studied to provide supporting or contrasting evidence. The researcher was herself a hcadtcacher and the project was designed to take advantage of her access to heads and be compatible with full time employment.

 The data are presented as case study reports in chapter three and answers to the research questions in chapter four. The resulting insights into the nature of headship can be found in chapter five which considers the emerging themes and conclusions.

 Headship emerges as a holistic role rather than a series of tasks or activities. Five interlinked themes are seen as encapsulating the nature of headship. These are: scope and complexity; leadership and management of change; the impact of the context; managing dilemmas; and the nature of the head’s accountability. The nature of these themes and the way in which they overlap emphasise the comprehensive and holistic quality of the role and the advanced nature of the required skills, qualities and experience.

description: Carbon dioxide removal and climate change adaptation are rarely analyzed together, yet it is critical to consider the interactions between these forms of climate response. We identify ways to foreground adaptation in carbon removal policies and project designs and to incorporate carbon removal into adaptation efforts. Attempts at aligning adaptation and carbon removal may genuinely increase adaptive capacity or introduce new vulnerabilities, depending on policy and project design. Based upon four case studies of addressing adaptation needs with adaptive carbon removal, we find that effective implementation is likely to hinge upon predictable climate policy, innovative technical policies such as rigorous life-cycle assessment, and project design with local ecological conditions in mind. We propose three simple principles for integrating carbon removal and adaptation: identify opportunities for adaptive carbon removal in planning, prioritize adaptive value of projects, and give credit for carbon removed.
Quantum Entanglement in the Two Impurity Kondo Model

description: In order to quantify quantum entanglement in two impurity Kondo systems, we calculate the concurrence, negativity, and von Neumann entropy. The entanglement of the two Kondo impurities is shown to be determined by two competing many-body effects, the Kondo effect and the Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction, $I$. Due to the spin-rotational invariance of the ground state, the concurrence and negativity are uniquely determined by the spin-spin correlation between the impurities. It is found that there exists a critical minimum value of the antiferromagnetic correlation between the impurity spins which is necessary for entanglement of the two impurity spins. The critical value is discussed in relation with the unstable fixed point in the two impurity Kondo problem. Specifically, at the fixed point there is no entanglement between the impurity spins. Entanglement will only be created (and quantum information processing (QIP) be possible) if the RKKY interaction exchange energy, $I$, is at least several times larger than the Kondo temperature, $T_K$. Quantitative criteria for QIP are given in terms of the impurity spin-spin correlation.

description: Intelligence affects the social outcomes of groups. A systematic study of the link is provided in an experiment where two groups of subjects with different levels of intelligence, but otherwise similar, play a repeated prisoner’s dilemma. Initial cooperation rates are similar, but increase in the groups with higher intelligence to reach almost full cooperation, while they decline in the groups with lower intelligence. Cooperation of higher intelligence subjects is payoff sensitive and not automatic: in a treatment with lower continuation probability there is no difference between different intelligence groups.

description: Cucumis melo var. reticulatus Ser. (or netted melon ‘Earl’s Favourite’), a variety of Cucumis melo L., is widely cultivated in Shizuoka, Japan. However, the leaves and stems are discarded after harvest. Therefore, we investigated the chemical constituents of melon leaves to suggest potential applications. Air-dried melon leaves were extracted using methanol. The methanol extract was suspended in water and successively partitioned using n-hexane, ethyl acetate, and to yield each fraction. Eight flavone glycosides (1 − 8) and three terpenes (9 − 11) were obtained. The chemical structures of these compounds were determined via nuclear magnetic resonance and mass spectrometry. The antioxidant activity of compounds 1 − 8 was evaluated using a 2,2-diphenyl-1-picrylhydrazyl radical assay. All compounds showed radical-scavenging activity in the range of IC50, 24.2 − 129.5 μM, which depended on the number of hydroxyl groups on the benzene ring and ortho-substitution. Therefore, the leaves of C. melo may be considered valuable material for developing antioxidants.

description: Large private firms are still relatively rare in low-income countries, and we know little about how entry-level managers in these firms are selected. We examine a context in which nearly 80 percent of production line workers are female, but 95 percent of supervisors are male. We evaluate the effectiveness of female supervisors by implementing a training program for selected production line workers. Prior to the training, we find that workers at all level of the factory believe males are more effective supervisors than females. Careful skills diagnostics indicate that those perceptions do not always match reality. When the trainees are deployed in supervisory roles, production line workers initially judge females to be significantly less effective, and there is some evidence that the lines on which they work underperform. But after around four months of exposure, both perceptions and performance of female supervisors catch up to those of males. We document evidence that the exposure to female supervisors changes the expectations of male production workers with regard to promotion and expected tenure in the factory.

description: The excellent mechanical properties of the Ni-based superalloy IN718 mainly result from coherent $γ''$ precipitates. Due to a strongly anisotropic lattice misfit between the matrix and the precipitate phase, the particles exhibit pronounced plate-shaped morphologies. Using a phase-field model, we investigate various influencing factors that determine the equilibrium shapes of $γ"$ precipitates, minimizing the sum of the total elastic and interfacial energy. Upon increasing precipitate phase fractions, the model predicts increasingly stronger particle-particle interactions, leading to shapes with significantly increased aspect ratios. Matching the a priori unknown interfacial energy density to fit experimental $γ"$ shapes is sensitive to the phase content imposed in the underlying model. Considering vanishing phase content leads to 30% lower estimates of the interfacial energy density, as compared to estimates based on realistic phase fractions of 12%. We consider the periodic arrangement of precipitates in different hexagonal and rectangular superstructures, which result from distinct choices of point-symmetric and periodic boundary conditions. Further, non-volume conserving boundary conditions are implemented to compensate for strains due to an anisotropic lattice mismatch between the $γ$ matrix and the $γ''$ precipitate. As compared to conventional boundary conditions, this specifically tailored simulation configuration does not conflict with the systems periodicity and provides substantially more realistic total elastic energies at high precipitate volume fractions. The energetically most favorable superstructure is found to be a hexagonal precipitate arrangement.

Iterative Algebraic Soft-Decision List Decoding of Reed-Solomon Codes

description: In this paper, we present an iterative soft-decision decoding algorithm for Reed-Solomon codes offering both complexity and performance advantages over previously known decoding algorithms. Our algorithm is a list decoding algorithm which combines two powerful soft decision decoding techniques which were previously regarded in the literature as competitive, namely, the Koetter-Vardy algebraic soft-decision decoding algorithm and belief-propagation based on adaptive parity check matrices, recently proposed by Jiang and Narayanan. Building on the Jiang-Narayanan algorithm, we present a belief-propagation based algorithm with a significant reduction in computational complexity. We introduce the concept of using a belief-propagation based decoder to enhance the soft-input information prior to decoding with an algebraic soft-decision decoder. Our algorithm can also be viewed as an interpolation multiplicity assignment scheme for algebraic soft-decision decoding of Reed-Solomon codes.

description: In this project we created an expandable framework for allowing infinite walking in virtual reality in a closed play area. A saccade is a rapid eye movement with a unique property: the eye temporarily gathers reduced information - saccadic suppression. We leverage the suppression to redirect the user's walking towards the center of the play area by rotating the virtual world around the camera's location. With the VR environment and corresponding pre and post experience questions we could already show an improvement in understanding on a set of participants. Modern VR hardware such as the Vive Eye Pro allows a reasonable sample rate of eye movement measurements. A self-developed VR testing environment was used and with corresponding pre and post experience questions we tested a group of participants regarding general motion and VR- sickness parameters. We found a certain angle for the maximum saccade rotation which was base of further testing. We found, that our framework and the default settings successfully allow saccadic redirection with only marginal discomfort for the users.

description: We explore how the multi-dimensional aspects of information released by the FOMC has effects on both market and real economic variables. Using tools from computational linguistics, we measure the information released by the FOMC on the state of economic conditions, as well as the guidance the FOMC provides about future monetary policy decisions. Employing these measures within a FAVAR framework, we find that shocks to forward guidance are more important than the FOMC communication of current economic conditions in terms of their effects on market and real variables. Nonetheless, neither communication has particularly strong effects on real economic variables.
MAIN DIRECTIONS OF LINGUOCULTURAL RESEARCH IN LINGUISTICS
Creators: name: Erkaeva, Dilnoza
Publisher: name: Zenodo
Year: 2025

description: This article delves into the main directions of linguocultural research in linguistics, a rapidly growing field that examines the interplay between language and culture. As linguistic anthropology gained momentum at the end of the 20th century, a shift in focus occurred toward understanding how language reflects and influences culture. The article outlines key areas such as ethnolinguistics, sociolinguistics, and linguoculturology, highlighting their role in the analysis of cultural phenomena through language. It discusses the theoretical foundations of these fields, the methodologies used, and their relevance in modern linguistic studies. Furthermore, it addresses the challenges and future directions for research in this interdisciplinary domain, including its integration with cognitive sciences and cultural studies.

description: Parton distributions in a {\it{valon}} in the next-to-leading order is used to determine the patron distributions in pion and kaon. The validity of the valon model is tested and shown that the partonic content of the valon is universal and independent of the valon type. We have evaluated the valon distribution in pion and kaon, and in particular it is shown that the results are in good agreement with the experimental data on pion structure in a wide range of $x=[10^{-4},1]$

description: Two other species, apparently of the same genus, are represented by various specimens from the same horizon, in Montana. One of these, which may be called Ornithomimus tenuis, was about twice the bulk of the present form. The third metatarsal was much more compressed transversely, both in the shaft and distal end. The bone was also much more slender medially than in the above species. The transverse diameter of this metatarsal at its distal end was 30mm., and the antero-posterior diameter, 35mm.

description: Models of single district plurality elections show that with three parties anything can happen - extreme policies can win regardless of voter preferences. I show that when single district elections are used to fill a legislature we get back to a world where the median voter matters. An extreme policy will generally only come about if it is preferred to a more moderate policy by the median voter in a majority of districts. The mere existence of a centrist party can lead to moderate outcomes even if the party itself wins few seats. Furthermore, I show that while standard single district elections always have misaligned voting i.e. some voters do not vote for their preferred choice, equilibria of the legislative election exist with no misaligned voting in any district. Finally, I show that when parties are impatient, a fixed rule on how legislative bargaining occurs will lead to more coalition governments, while uncertainty will favour single party governments.

description: We evaluate the ability of the Lucas [25] tree and the Alvarez-Jermann [3] models, both with homogeneous as well as heterogeneous beliefs, to generate a time series of excess returns that displays both short-term momentum and long-term reversal, i.e., positive autocorrelation in the short-run and negative autocorrelation in the long-run. Our analysis is based on a methodological contribution that consists in (i) a recursive characterisation of the set of constrained Pareto optimal allocations in economies with limited enforceability and belief heterogeneity and (ii) an alternative decentralisation of these allocations as competitive equilibria with endogenous borrowing constraints. We calibrate the model to U.S. data as in Alvarez and Jermann [4]. We find that only the Alvarez-Jermann model with heterogeneous beliefs delivers autocorrelations that not only have the correct sign but are also of magnitude similar to the US data.
