description: Η διατριβή βασίζεται στη διδασκαλία της λογοτεχνίας κατά το σχολικό έτος 2011-12 σε 5 τμήματα της Α΄ Λυκείου του 2ου Γενικού Λυκείου Κατερίνης, όπου εργάζομαι. Το ΦΕΚ 1562/27-6-2011 (σ. 21068-21082), που αφορά στο μάθημα της Λογοτεχνίας στην Α΄ τάξη, έρχεται να γενικεύσει την προσπάθεια πολλών εκπαιδευτικών τις δύο τελευταίες δεκαετίες να φέρουν ένα νέο άνεμο στη σχολική πράξη. Επιχειρώντας να προχωρήσουν πέρα από την παραδοσιακή Εμπειρική Παιδαγωγική και συνδυάζοντας στοιχεία της Ερμηνευτικής και της Κριτικής Παιδαγωγικής, οι εκπαιδευτικοί γίνονται διανοούμενοι κι ερευνητές, με ενεργό ρόλο στη διαμόρφωση του Προγράμματος Σπουδών, σε συνεργασία με τον ‘κριτικό φίλο’ και τους μαθητές τους. Στο 1ο σενάριο, με θέμα «Τα φύλα στη λογοτεχνία», εξετάζεται η πορεία και η διαφοροποίηση του ρόλου κάθε φύλου στην ιστορία, διαβάζεται ολόκληρο μυθιστόρημα και παράγεται προσωπικός λόγος. Στο 2ο σενάριο, με θέμα «Παράδοση και μοντερνισμός στην ποίηση», διαβάζονται ποιητικές συλλογές και παρουσιάζονται διάφορα λογοτεχνικά ρεύματα. Καθ’ όλη τη διάρκεια του έτους στο ‘Νέο Λύκειο’ οι μαθητές εργάζονται ατομικά και σε ομάδες, παρακολουθούν ταινίες, συμπληρώνουν φύλλα εργασίας και αξιολογούν τη διαδικασία.
description: This study is based on the teaching of literature during the school year 2011-12 in the class of fifteen year old students in 2nd High School of Katerini, where I work. With the new syllabus (Gov. 1562/27-6-2011: 21068-21082), teachers become scholars and researchers with an active role in shaping the Curriculum in collaboration with the ‘critical friend’ and their students. In the first scenario, “Gender in literature” students examine the state and differentiation of gender roles in history, read entire novels and write their own essays. In the second scenario, “Tradition and modernism in poetry”, students read poetry and present several literary movements. Throughout the year students work both individually and in groups, watch movies, complete worksheets and evaluate the process.

Στη σύγχρονη Ιατρική Εκπαίδευση, χρησιμοποιούνται οι εικονικοί ασθενείς, ένα μέσο μάθησης που βασίζεται στην προσπέλαση σεναρίων, για την εκπαίδευση επαγγελματιών υγείας. Οι εικονικές περιπτώσεις ασθενών προσφέρουν έναν πλούτο στατικών πληροφοριών, καθώς και δυναμικά δεδομένα που μπορούν να συλλέγονται κατά τη διάρκεια της χρήσης τους. Η διάρθρωση των εν λόγω πληροφοριών σε μια επίσημη και τυποποιημένη μορφή, όπως εξετάζεται στην παρούσα εργασία, μπορεί να γίνει με τη βοήθεια του Resource Description Framework. Η διαδικασία υλοποιήθηκε στο Open Labyrinth, μία ανοιχτού κώδικα πλατφόρμα εικονικών ασθενών. Η δομημένη αναπαράσταση των δεδομένων των περιπτώσεων προσφέρει νέες ευκαιρίες για τους εκπαιδευτικούς σχεδιαστές όσον αφορά την ανακάλυψη των εικονικών ασθενών από τους ενδιαφερόμενους φοιτητές αλλά και της αξιολόγησης φοιτητών και εικονικών ασθενών, ενώ η ανάπτυξη πιο εξελιγμένων χαρακτηριστικά είναι πλέον δυνατή και φαίνεται πολλά υποσχόμενη.
description: Semantically rich metadata are already used to annotate resource collections, in order to make them easier to discover, assess and reuse. Modern Medical Education utilizes virtual patients, a scenario-based learning medium, to train healthcare professionals. The virtual patient cases offer a wealth of static information as well as metadata that can be collected during their use. The structuring of this information in a formal and standardized way is examined in this thesis, with the help of the Resource Description Framework. The procedure is realized in Open Labyrinth, an open source virtual patients platform. The structured representation of the cases’ data offers new opportunities for the case designers, in terms of discovery and assessment, while the development of more sophisticated features is now possible and looks promising.

description: The farm sector seems to be recovering from the financial stress of the early to mid-1980's. Many individual farmers experienced considerable financial difficulties, but the recession did not cause major changes in the basic structure of U.S. farming: farm numbers and land in farms declined in the 1980’s while average farm size increased. These are following long-term trends, but the rates of change have slowed each decade. Asset values fell drastically during the recent recession, but the declines are moderating. The distribution of farmers by operator tenure, average age, principal occupation, and off-farm work practices changed little since 1982. However, there are significant geographic variations from the national trends in farm structure. This report contains 1987 Census of Agriculture data on various characteristics of farm structure in the 1980's and describes the farm economy as it enters the new decade.
Dynamical Detection of Singly-Transiting Circumbinary Planets

Publisher: name: University of Chicago
Year: 2019
Subjects: subject: planets and satellites: detection
subject: binaries: eclipsing

description: Circumbinary planets (CBPs) are exoplanets that orbit completely around a pair of stars. CBPs provide a unique perspective on planet formation and evolution, but the current sample of transiting circumbinary planets is too small to draw conclusions on the population as a whole. Key questions include the distribution of orbital distances compared to the stability limit as well as the coplanarity of circumbinary systems. We searched for transiting circumbinary planets in the catalog of eclipsing binaries from the K2 mission. We found two candidate single-transit events, including one that might show asymmetry in the durations of ingress and egress that could be produced by the acceleration of the star during the transit. We use a simplified photodynamical model that simulates the planet during the transit and constrains its motion. Furthermore, we use eclipse timing variations caused by the apsidal precession of the binary to constrain the mass and orbit of this planet, although a full orbital solution is not possible. Our results suggest there is a possibility to discover and constrain more CBPs by searching in shorter-baseline photometric data from K2 or TESS, which observe more stars than Kepler but for much shorter durations.
Breastfeeding and Triple Negative Breast Cancer: Mechanisms and Opportunities to Alleviate Racial Disparities

Subjects: subject: cancer
subject: breast feeding
subject: disparities

description: Abstract African American women are both more likely to develop and die from Triple Negative Breast Cancer than their white counterparts. Concurrently, African American women breastfeed at significantly lower rates than white mothers. These two overlapping disparities highlight potential epidemiological, but more importantly epigenetic mechanisms for addressing and eliminating the racial disparity in breast cancer mortality. Breastfeeding is highly associated with multiple cancers, including Triple Negative Breast, through hormonal changes. But recent evidence is also suggesting immunoprotein contributors, as well as permanent microenvironment and genetic transcription changes after breastfeeding which may influence tumorigenesis in the breast. While scientific research has led to confident claims about the mechanistic framework for breastfeeding as a protective factor, little has translated to clinical outcomes aside from greater promotion of breastfeeding. The following paper reviews the literature on the mechanisms for breastfeeding as a protective factor against breast cancer and concludes with a discussion on clinical and translational opportunities to improve outcomes and eliminate the disparity in mortality.

Infrastructure Resilience Curves: Performance Measures and Summary Metrics

Year: 2021
Subjects: subject: Distributed, Parallel, and Cluster Computing (cs.DC)
subject: FOS: Computer and information sciences

description: Resilience curves are used to communicate quantitative and qualitative aspects of system behavior and resilience to stakeholders of critical infrastructure. Generally, these curves illustrate the evolution of system performance before, during, and after a disruption. As simple as these curves may appear, the literature contains underexplored nuance when defining "performance" and comparing curves with summary metrics. Through a critical review of 273 publications, this manuscript aims to define a common vocabulary for practitioners and researchers that will improve the use of resilience curves as a tool for assessing and designing resilient infrastructure. This vocabulary includes a taxonomy of resilience curve performance measures as well as a taxonomy of summary metrics. In addition, this review synthesizes a framework for examining assumptions of resilience analysis that are often implicit or unexamined in the practice and literature. From this vocabulary and framework comes recommendations including broader adoption of productivity measures; additional research on endogenous performance targets and thresholds; deliberate consideration of curve milestones when defining summary metrics; and cautionary fundamental flaws that may arise when condensing an ensemble of resilience curves into an "expected" trajectory.

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

description: We point out that, if R-parity is broken spontaneously, the neutralino can decay to the final state majoron plus neutrino, which from the experimental point of view is indistinguishable from the standard missing momentum signal of supersymmetry. We identify the regions of parameter space where this decay mode is dominant and show that they are independent of R-parity conserving SUSY parameters. Thus, (a) only very weak limits on R-parity violating couplings can be derived from the observation of missing momentum events and (b) at future collider experiments huge statistics might be necessary to establish that R-parity indeed is broken. Parameter combinations which give calculated relic neutralino density larger than the measured dark matter density in case of conserved R-parity are valid points in this scenario and their phenomenology at the LHC deserves to be studied.

description: This paper derives the speed of light  **c(ρₛ) = c₀ · cos(πρₛ / 2)**  as a geometric consequence of local spacetime torsion, based on the structured resonance framework presented in *Principia Universalis*.

It formally corrects earlier averaging approximations and provides a clean, testable derivation aligned with Euler’s identity *(e^{iπ} + 1 = 0)* and the Universal identity *(e^{i2π} = 1)*. A terrestrial example is included, along with practical guidance for experimental validation using fine-structure phase offsets near Earth’s surface.

description: We study a Lie algebra type $κ$-deformed space with undeformed rotation algebra and commutative vector-like Dirac derivatives in a covariant way. Space deformation depends on an arbitrary vector. Infinitely many covariant realizations in terms of commuting coordinates of undeformed space and their derivatives are constructed. The corresponding coproducts and star products are found and related in a new way. All covariant realizations are physically equivalent. Specially, a few simple realizations are found and discussed. The scalar fields, invariants and the notion of invariant integration is discussed in the natural realization.

Προς επίρρωση της εν λόγω θέσης, επιστρατεύθηκαν τα μεθοδολογικά εργαλεία του συγκριτικού δικαίου. Ειδικότερα, μέσα από μια επισταμένη έρευνα αλλοδαπών νομοθεσιών αλλά και τη συγκριτική επισκόπηση του εθνικού νομοθετικού πλαισίου σε σχέση με συναφή νομολογιακά παραδείγματα του κοινοτικού δικαίου, προέκυψε ότι η φορολογική διαφάνεια λειτουργώντας ως ένα ορμητήριο δημόσιου διαλόγου και διαβούλευσης της εφαρμοστέας πολιτικής δύναται τελικώς να λειτουργήσει ως μια διάμεσος διαμόρφωσης ενός νέου κοινωνικού συμβολαίου μεταξύ πολιτών και κράτους. Ως αντιστάθμισμα στην εκπλήρωση ενός τέτοιου σκοπού δημοσίου συμφέροντος πρέπει να τίθεται πάντα η υποχρέωση διαφύλαξης της προστασίας της ιδιωτικής ζωής και των προσωπικών δεδομένων των ατόμων με γνώμονα την αρχή της αναλογικότητας. Μια τέτοια πρακτική εναρμόνιση επιχειρήθηκε και εν τέλει συντελέστηκε στην περίπτωση της δημοσιοποιήσεως των ονομάτων οφειλετών του Δημοσίου στο Διαδίκτυο, η οποία λειτούργησε ως case study για τις ανάγκες της παρούσας μελέτης.
description: The main idea behind this thesis is the view that the principle of tax transparency, although gradually established in the international and Community legal orders as merely a factor guaranteeing the achievement of macro-economic objectives by the national States, ultimately bears in its proper conception an incalculable power of democratization of governance. In support of this view, we implemented the methodology instruments of comparative law. In particular, through a thorough research of foreign legislations and the comparative overview of the national legislative framework, we reached the conclusion that tax transparency, operating as the springboard of public dialogue and consultation on the applicable policy, can serve as a medium of creation of a new social contract between citizens and the State. In order to compensate for the achievement of such a public interest objective, the obligation of ensuring the protection of privacy and personal data must always be adhered to, in line with the principle of proportionality. Such a practical harmonization was attempted and finally implemented in the case of the Internet disclosure of names of debtors to the State, which served as a case study in the present paper.

description: Complex networks are universal, arising in fields as disparate as sociology, physics, and biology. In the past decade, extensive research into the properties and behaviors of complex systems has uncovered surprising commonalities among the topologies of different systems. Attempts to explain these similarities have led to the ongoing development and refinement of network models and graph-theoretical analysis techniques with which to characterize and understand complexity. In this tutorial, we demonstrate through illustrative examples, how network measures and models have contributed to the elucidation of the organization of complex systems.

Timescale of variation and the size of the accretion disc in active galactic nuclei
Creators: name: Hawkins, M. R. S.
Publisher: name: arXiv
Year: 2006
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: This paper sets out to measure the timescale of quasar variability with a view to new understanding of the size of accretion discs in active galactic nuclei. Previous attempts to measure such timescales have been based on sparsely sampled data covering small ranges of time. Here we combine data from two large scale monitoring programmes to obtain Fourier power spectra of light curves covering nearly three orders of magnitude in frequency in blue and red passbands. If the variations are interpreted as due to gravitational microlensing, then timescale measurements in the observer's frame imply a minimum mass for the microlensing bodies of around $0.4 M_{\odot}$. On the assumption that the variations are intrinsic to the quasars, a correction must be made for time dilation. In this case the power spectrum shows a break corresponding to a timescale of about 11 years. This timescale is used to measure the size of the accretion disc, which is found to be about $10^{-2}$ pc or 10 light days, in agreement with limits set by self-gravitation and coincident with the broad line region of the active galactic nucleus. It is suggested that the broad line region may be associated with the break up of the outer part of the accretion disc.

description: The aim of the present thesis was the study of the phenomenon of dyslexia. We presented the international scientific definitions, the symptoms, the reasons as well as the additional disruptions and difficulties that accompany dyslexia and the ways we can face them emphasizing on education. We mainly focused on dyslexic children’s difficulties concerning learning the English language and showed some ways to be faced through the use of multimedia. Besides we compared the difficulties of native Greek children to those of native English children and we spotted the problems the Greek children face while learning the English language. Then we suggested some methods of teaching English in the classroom. Finally we introduced the technological methods available in the market to face dyslexia symptoms.

description: The aim of the present study was to examine in the light of the Platonic philosophy, the theoretical positions on art made by Vasily Kandinsky, one of the founders of abstract art. The theoretical aspects of Kandinsky in their entirety almost, enclose origins from ancient Greek philosophy, mostly platonic. As follows, taking into account the political - social -economic conditions of the time where it appeared and also the philosophical theories, movements and doctrines, which provided the basis for his positions, we attempted to show that, to some extent, the roots of Kandinsky’s positions but also of abstract art in general, are the philosophical positions of Plato and of subsequent philosophers and thinkers, successors of the platonic thought.

description: We report accurate measurements of the equation of state (EOS) of cubic boron nitride by x-ray diffraction up to 160 GPa at 295 K and 80 GPa in the range 500-900 K. Experiments were performed on single-crystals embedded in a quasi-hydrostatic pressure medium (helium or neon). Comparison between the present EOS data at 295 K and literature allows us to critically review the recent calibrations of the ruby standard. The full P-V-T data set can be represented by a Mie-Grüneisen model, which enables us to extract all relevant thermodynamic parameters: bulk modulus and its first pressure-derivative, thermal expansion coefficient, thermal Grüneisen parameter and its volume dependence. This equation of state is used to determine the isothermal Grüneisen mode parameter of the Raman TO band. A new formulation of the pressure scale based on this Raman mode, using physically-constrained parameters, is deduced.

description: This report contains the 2nd draft of general guidelines for making management recommendations (MRs) tailored for the EU fleet operating outside European waters; in accordance with the responsive fisheries management system (RFMS). The RFMS is a management approach founded on the concept of results-based management (RBM), where responsibility for fisheries management is to a point transferred to resource users, provided that they meet with necessary requirements set forth by the competent authorities and document that they can achieve specified management objectives. These 2nd draft guidelines follow up on the 1st version, which were developed within FarFish in early stages of the project. Stakeholders representing the relevant authorities and the EU fleet, as well as any other stakeholders with vested interests in the specific fisheries have followed the 1st draft version of these guidelines in order to develop 1st version MRs for their fisheries. These MRs have now been reviewed and audited; and the feedback used to improve the guidelines. This process will now be repeated within the project, as these 2nd draft general guidelines will be tested/validated within the FarFish case studies. The third and final version of the guidelines will then be published as a voluntary European standard (CEN Workshop Agreement) at the end of the project.

description: The purpose of this research is, on the one hand, to look into the beliefs of the teenage students regarding peace and violence and, on the other hand, to explore their information sources about these matters in order to show if the messages that they get through education and the social media create peace or war friendly personalities. Based on the beliefs of most students, teenagers perceive the social commotion, the democratic deficiency, the corrosion of the moral values. Therefore, they are aware of the modern social series of events but they still support -adopt this specific social coexistence as long as they do not actively participate in the change of the “current model social living”.

description: We introduce a stochastic model that describes the quasi-static dynamics of an electric transmission network under perturbations introduced by random load fluctuations, random removing of system components from service, random repair times for the failed components, and random response times to implement optimal system corrections for removing line overloads in a damaged or stressed transmission network. We use a linear approximation to the network flow equations and apply linear programming techniques that optimize the dispatching of generators and loads in order to eliminate the network overloads associated with a damaged system. We also provide a simple model for the operator's response to various contingency events that is not always optimal due to either failure of the state estimation system or due to the incorrect subjective assessment of the severity associated with these events. This further allows us to use a game theoretic framework for casting the optimization of the operator's response into the choice of the optimal strategy which minimizes the operating cost. We use a simple strategy space which is the degree of tolerance to line overloads and which is an automatic control (optimization) parameter that can be adjusted to trade off automatic load shed without propagating cascades versus reduced load shed and an increased risk of propagating cascades. The tolerance parameter is chosen to describes a smooth transition from a risk averse to a risk taken strategy...

Minority policy in post-Mao China
Creators: name: Ip, Catherine Kwai Po
Publisher: name: University of British Columbia

description: One of the most potent political forces in the world today is ethnicity. Contrary to the predictions of the developmentalists, ethnicity has not disappeared. Likewise, contrary to the beliefs of the Marxists, a shedding of "false consciousness" to erode the power of ethnicity has not occurred. One of the important tasks of a state is to deal successfully with the challenges posed by the presence of ethnic cleavages. The possible strategies to be employed range on a spectrum from a multi-cultural accommodative approach, to the "melting pot", to an assimilationist approach. The purpose of this thesis is to examine the strategies employed by the government in post-Mao China to ensure the compliance of the ethnic minorities, who comprise 91 million people (8 percent) residing in over 64 percent of China's territory, mostly along its borders. The central questions of this thesis are as follows: (1) What have been the strategies employed to ensure the compliance and/or secure the loyalty of the ethnic minorities?; (2) Have these strategies been consistent over time or have they varied, and why?; (3) Have these strategies been successful or not in securing compliance and/or promoting loyalty? Two of the major approaches used to analyze policies in China - of cycles or alternations - will be used to analyze China's post-Mao policies towards the ethnic minorities. This thesis concludes that a liberal line on minority policy has re-emerged in postii Mao China, which resembled the "velvet fist" of the former Soviet Union - tolerance and accommodation within certain parameters which did not challenge the integrity of the state. The results of these strategies have been mixed. For those ethnic minorities whose immediate concern is economic betterment, the current strategies have been successful in securing compliance and apparently in promoting loyalty. However, the prevailing accommodative approach has not been successful in ensuring the acquiescence, let alone compliance, of the minorities in certain areas, like Tibet, Xinjiang, and Inner Mongolia. Along with accommodative strategies, therefore, the Chinese government has employed coercive power to maintain order in these regions.

description: We describe a system for rapidly measuring the brightness of the night sky using a mosaic of CCD images obtained with a low-cost automated system. The portable system produces millions of independent photometric measurements covering the entire sky, enabling the detailed characterization of natural sky conditions and light domes produced by cities. The measurements are calibrated using images of standard stars contained within the raw data, producing results closely tracking the Johnson V astronomical standard. The National Park Service has collected hundreds of data sets at numerous parks since 2001 and is using these data for the protection and monitoring of the night-sky visual resource. This system also allows comprehensive characterization of sky conditions at astronomical observatories. We explore photometric issues raised by the broadband measurement of the complex and variable night-sky spectrum, and potential indices of night-sky quality.

Superstring Scattering from O-planes

description: We write the vertex operators of massless NS-NS and RR states of Type II superstring theory in the presence of Orientifold p-planes. They include the usual vertex operators of Type II theory and their images. We then calculate the two-point functions of these vertex operators at the projective plane PR_2 level. We show that the result can be written in the Veneziano-type formulae, with the same kinematic factor that appears in the D_p-branes amplitudes. While the scattering amplitudes with the usual vertex operators are not gauge invariant, the above amplitudes are invariant. From the amplitude describing scattering of two NS-NS states off the O-plane, we find the low energy effective action of O-planes. The result shows a relative factor 2^{p-6} between couplings to O-planes and to D-branes at (α')^2 order.

Sparse estimation of large covariance matrices via a nested Lasso penalty

description: The paper proposes a new covariance estimator for large covariance matrices when the variables have a natural ordering. Using the Cholesky decomposition of the inverse, we impose a banded structure on the Cholesky factor, and select the bandwidth adaptively for each row of the Cholesky factor, using a novel penalty we call nested Lasso. This structure has more flexibility than regular banding, but, unlike regular Lasso applied to the entries of the Cholesky factor, results in a sparse estimator for the inverse of the covariance matrix. An iterative algorithm for solving the optimization problem is developed. The estimator is compared to a number of other covariance estimators and is shown to do best, both in simulations and on a real data example. Simulations show that the margin by which the estimator outperforms its competitors tends to increase with dimension.

Deaf education and the claims of the deaf
Creators: name: Hole, Rachelle Deanne
Publisher: name: University of British Columbia

description: Historically deaf education has been dominated by an ongoing struggle between interest groups regarding methods of communication. It is a context where the claims of different groups have had disparate influence on policy. The claims of the Deaf, the linguistic minority group, have been silenced in this historical context. Adopting a theoretical perspective of claimsmaking this qualitative study explored the process by which professionals reached their respective beliefs regarding communication policy. Nine professionals representing the three major communication methods used in deaf education (auditory/oralism, total communication, and bilingual/biculturalism) were interviewed. It was found that the participants' processes of reaching their respective views were subjective, being influenced by such factors as their view of deafness, their personal identity as hearing or deaf, their world view, their life experiences and their educational philosophy. This finding points to the importance of professionals examining how their own culture, experiences and history influence their beliefs which in turn influences practice. In addition the findings highlight the reality that the Deaf are the only ones in society with firsthand knowledge and experience of what it means to be deaf in a hearing society. Therefore, the Deaf can offer valuable insight about the needs of deaf children and should be critical actors in the process of policy development.
Self-dual models in $D=2+1$ from dimensional reduction

description: Here we perform a Kaluza-Klein dimensional reduction of Vasiliev's first-order description of massless spin-s particles from $D=3+1$ to $D=2+1$ and derive first-order self-dual models describing particles with helicities $\pm s$ for the cases $s=1,2,3$. In the first two cases we recover known (parity singlets) self-dual models. In the spin-3 case we derive a new first order self-dual model with a local Weyl symmetry which lifts the traceless restriction on the rank-3 tensor. A gauge fixed version of this model corresponds to a known spin-3 self-dual model. We conjecture that our procedure can be generalized to arbitrary integer spins.

description: Piezoresponse Force Microscopy contrast in transversally isotropic material corresponding to the case of c+ - c- domains in tetragonal ferroelectrics is analyzed using Green's function theory by Felten et al. [J. Appl. Phys. 96, 563 (2004)]. A simplified expression for PFM signal as a linear combination of relevant piezoelectric constant are obtained. This analysis is extended to piezoelectric material of arbitrary symmetry with weak elastic and dielectric anisotropies. This result provides a framework for interpretation of PFM signals for systems with unknown or poorly known local elastic and dielectric properties, including nanocrystalline materials, ferroelectric polymers, and biopolymers.

description: This report shows which groups of farms received Government farm program payments in 1987, in what amount, and in what proportion. Since they were started in the 1930’s farm programs have distributed payments to producers of specific commodities based primarily on the producer's volume of production of those commodities. Data from the 1987 Census of Agriculture show that cash grain producers received the majority of payments, the largest proportion of any of the farm types. Farms with over $1 million in sales accounted for only one-half of 1 percent of the farms receiving payments but these farms accounted for over 3 percent of the payments reported.

description: Talent Development (TD) in the context of Nigerian athletes presents a distinctive landscape characterized by intricate socio-cultural barriers, as highlighted by Elumaro et al. (2016). In contrast to counterparts in diverse cultures, Nigerian athletes encounter unique challenges that significantly impede the process of talent development. This study delves into the profound revelations made by Elumaro et al. (2016) and investigates the multifaceted socio-cultural barriers hindering sports development in Nigeria. The examination of the TD landscape in Nigeria reveals a complex interplay of factors that pose challenges for athletes aspiring to develop their talents. Previous research by Martindale et al. (2007) emphasized the necessity of a comprehensive talent development environment, advocating for a network of consistent and coherent support from various stakeholders. These stakeholders encompass parents, coaches, teachers, siblings, and friends, each playing a crucial role in fostering an effective talent development framework. Nigerian athletes, however, face a distinctive set of hurdles, surpassing those encountered by their counterparts in other cultures. The socio-cultural barriers identified by Elumaro et al. (2016) encompass a myriad of challenges, ranging from societal expectations and norms to familial and peer influences. Understanding and navigating these barriers become imperative for successful talent development in the Nigerian sporting context. This study critically examines the implications of these socio-cultural barriers on the talent development trajectory of Nigerian athletes. By shedding light on the unique challenges faced by athletes in Nigeria, the research aims to contribute to the development of targeted interventions and strategies. Furthermore, it seeks to foster a deeper understanding of the underlying dynamics that shape the TD landscape in the Nigerian context.
Controlling the order of wedge filling transitions: the role of line tension

description: We study filling phenomena in 3D wedge geometries paying particular attention to the role played by a line tension associated with the wedge bottom. Our study is based on transfer matrix analysis of an effective one dimensional model of 3D filling which accounts for the breather-mode excitations of the interfacial height. The transition may be first-order or continuous (critical) depending on the strength of the line tension associated with the wedge bottom. Exact results are reported for the interfacial properties near filling with both short-ranged (contact) forces and also van der Waals interactions. For sufficiently short-ranged forces we show the lines of critical and first-order filling meet at a tricritical point. This contrasts with the case of dispersion forces for which the lines meet at a critical end-point. Our transfer matrix analysis is compared with generalized random-walk arguments based on a necklace model and is shown to be a thermodynamically consistent description of fluctuation effects at filling. Connections with the predictions of conformal invariance for droplet shapes in wedges is also made.
