Dyslexia is one of the most common reading disorders observed in children and adults across the world, yet it is also one of the most challenging for clinicians to diagnose and treat. The obstacles associated with detecting dyslexia and intervening with appropriate remediation therapies early in development largely stem from the heterogeneity of symptom presentation, complicated further by the delayed timeline for acquiring literacy. Over the last several decades and until recently, neuropsychologists and linguists alike have posited numerous theories and models to aid in understanding the underlying causes of dyslexia. The following review presents a selection of the leading theories for explaining dyslexia from the behavioral literature, as well as the cognitive-behavioral evidence that supports these theories. In addition, a brief exploration of the genetic factors influencing dyslexia is covered, as well as a number of key findings from neuroimaging research that demonstrate specific neuroanatomical and functional perturbations which may serve as predictors of dyslexia in pre-literate children.

Abstract Underground mining exploitation may result in mining damages to building objects located on a terrain surface. Considering high harmfulness of this phenomenon, the scientists from all over the world have tried to describe impact of underground exploitation on deformations of terrain surface and objects located thereon. The first theories, based on the Gaussian distribution, have emerged in the 1950s and are in use until now. Later on, in connection with development of computational techniques, their availability and numerical methods, a possibility of numerical computations use for forecasting of deformations has emerged. These methods, when suitable numerical models are adopted, enable to include higher number of factors influencing the results being obtained. When constructing numerical model, particular attention should be paid on selection of: appropriate geometry of model, proper constitutive model describing behavior of rock and soil layers, adequate values of rock mass parameters prior to execution of mining exploitation, and after it. The author presented in this article part of these problems, based on own experience.

Indian dairy cultivating has been portrayed by co-agents including a large number of people. Indian extraordinary items have been comprehensively in the classifications of dairy and poultry items, vegetables and organic products, flavors, oats, oil seeds, consumable oils and certain prepared items. The Indian government's first monetary study expressed that India represents 17 percent of world generation of drain. The normal year-on-year development rate of drain at 4.04 percent versus the world normal of 2.2 percent demonstrates continued development in accessibility of drain and drain items for the developing populace. Keeping this in view the study has been directed to factors influencing the selection of store for purchasing of dairy products. The investigation has been conveyed by controlling an organized poll to gather the information from the respondents and anslysed it by utilizing SPSS 20.0. The examination uncovered that the main considerations impacting the buy choice are accessibility of items, close to home, credit office and the respondents are minimum made a big deal about the inside condition of the store.

Ben Jonson's early plays show a marked interest in prose as a counterpoint to the blank verse norm of the Renaissance stage. This essay presents a digital analysis of Jonson's early mixed-mode plays and his two later full-prose comedies. It examines this selection of the Jonsonian corpus using DocuScope, a piece of software that catalogs sentence-level features of texts according to a series of rhetorical categories, highlighting the distinctive linguistic patterns associated with Jonson's verse and prose. Verse tends to employ abstract, morally and emotionally charged language, while prose is more often characterized by expressions that are socially explicit, interrogative, and interactive. In the satirical economy of these plays, Jonson's characters usually adopt verse when they articulate censorious judgements, descending into prose when they wade into the intractable banter of the vicious world. Surprisingly, the prosaic signature that Jonson fashioned in his earlier drama persisted in the two later full-prose comedies. The essay presents readings of Every Man Out of his Humour and Bartholomew Fair, illustrating how the tension between verse and prose that motivated the satirical dynamics of the mixed-mode plays was released in the full-prose comedies. Jonson's final experiments with theatrical prose dramatize the exhaustion of the satirical impulse by submerging his characters almost entirely in the prosaic world of interactive engagement.

Mark Grimshaw-Aagaard addresses the role of sound in the creation of presence in virtual and actual worlds. He argues that imagination is a central part of the generation and selection of perceptual hypotheses—models of the world in which we can act—that emerge from what Grimshaw-Aagaard calls the “exo-environment” (the sensory input) and the “endo-environment” (the cognitive input). Grimshaw-Aagaard further divides the exo-environment into a primarily auditory and a primarily visual dimension and he deals with the actual world of his own apartment and the virtual world of first-person-shooter computer games in order to exemplify how we perceptually construct an environment that allows for the creation of presence.

Universities around the world have faced a new pandemic, forcing the closure of campuses that are now conducting educational activities on online platforms. The paper presents a survey about students behavior and attitudes towards online education in the pandemic period from the Technical University of Cluj Napoca, Romania. A group of 300 students participated. The questionnaire was structured in four parts to determine student’s individual characteristics, student’s needs, students’ knowledge in using virtual platforms and students’ quality preferences for online education. The students said that online education in a pandemic situation is beneficial for 78% of them. A total of 41.7% percent of students appreciated the teachers’ teaching skills and the quality of online courses since the beginning of the pandemic, and 18.7% percent of the students appreciated the additional online materials for study to support their education. However, students found online education stressful, but preferred online assessment for evaluation. This pandemic has led to the new stage of Education 4.0, online education, and the need to harmonize methods of education with the requirements of new generations.

AbstractVarious scandals have shaken public confidence in football's global governing body, Fédération Internationale de Football Association (FIFA). It is evident that decision-making within such a collective provides incentives for corruption. We apply the Buchanan-Tullock model that is known from Public Choice theory to study collective decision-making within FIFA. On the basis of this theoretical model, we develop specific proposals that can contribute to combating corruption. Three core aspects are discussed: the selection of the World Cup host, transparency in the allocation of budgets, and clear guidelines for FIFA officials and bodies with regard to their rights and accountability. Our insights can contribute to a better understanding of collective decision making in heterogenous groups.

This article originates from the theoretical and empirical characterization of factors in the World Trade Model (WTM). It first illustrates the usefulness of this type of model for water research to address policy questions related to virtual water trade, water constraints and water scarcity. It also illustrates the importance of certain key decisions regarding the heterogeneity of water and its relation to the technologies being employed and the prices obtained. With regard to WTM, the global economic input–output model in which multiple technologies can produce a “homogeneous output”, it was recently shown that two different mechanisms should be distinguished by which multiple technologies can arise, i.e., from “technology-specific” or from “shared” factors, which implies a mechanism-specific set of prices, quantities and rents. We discuss and extend these characterizations, notably in relation to the real-world characterization of water as a factor (for which we use the terms technology specific, fully shared and “mixed”). We propose that the presence of these separate mechanisms results in the models being sensitive to relatively small variations in specific numerical values. To address this sensitivity, we suggest a specific role for specific (sub)models or key choices to counter unrealistic model outcomes. To support our proposal we present a selection of simulations for aggregated world regions, and show how key results concerning quantities, prices and rents can be subject to considerable change depending on the precise definitions of resource endowments and the technology-specificity of the factors. For instance, depending on the adopted water heterogeneity level, outcomes can vary from relatively low-cost solutions to higher cost ones and can even reach infeasibility. In the main model discussed here (WTM) factor prices are exogenous, which also contributes to the overall numerical sensitivity of the model. All this affects to a large extent our interpretation of the water challenges, which preferably need to be assessed in integrated frameworks, to account for the main socioeconomic variables, technologies and resources.
