Abstract:

The article deals with the research on the problem of blind and visually impaired teenagers’ psycho-logical correction, development and formation of self-construction. Optical defect influences personality development. Problems of personality formation are inseparable from the questions of social adaptation of children with profound visual impairment. The important aspect of adaptation is personality adaptation to his inner self. In the native and foreign scientists’ works, there are few re-searches on social adaptation and personality formation where the questions of blind and visually impaired personalities’ socialization and formation would be studied. The aim of the work is formation of positive self-construction within blind and visually impaired teenagers as a social adaptation factor through creating and testing of remedial programmes. The article gives the results of the research, conducted in two stages. With the aim of correcting, formation and development of teen-agers’ personality sphere, some remedial programmes were worked out. Positive dynamics demonstrates the effectiveness of remedial programmes on the formation of complex and positive self-construction as a factor of successful social adaptation, successfully implemented in Verkhnepyshminskaya School for five years.

Abstract:

AbstractDigital media offers multiple possibilities for inclusion of people with disabilities. Nevertheless, they pose barriers especially for blind learners as they hinder an active participation in synchronous learning settings. Virtual classrooms are a particularly good example for a complex media application as they combine various media types such as audio, video, graphical content and text which can only partially be perceived.Our work pursues the goal to facilitate an equal participation in virtual classrooms for blind users. In order to overcome these barriers, alternative user interface concepts for the display on a two-dimensional tactile Braille device have been conceived. Based on these concepts, the virtual classroom solution BigBlueButton was improved thereupon. A subsequent evaluation simulated a learning session with blind users in order to determine the acceptance and usability of the software adaptation. This user study shows that an active participation of blind learners in virtual classroom sessions can be achieved by using multimodal output devices and alternative concepts.

Abstract:

This study was aiming at helping visually impaired people to detect and estimate the fire distance. Blind people had difficulty knowing the existence of fire at a safe distance; hence the possibility of burning could occur. The color models and blob analysis methods were used to detect the presence of fire in the blind path. Before the fire detection stage, the cascade of the HSV and RGB color models was applied to segment the reddish fire color. The size and shape of a dynamic fire were the parameters used in this paper to distinguish fire from non-fire objects. Changes in the area of the fire object obtained at the Blob analysis stage per 10 frames were the main contributions and novelty in this paper. After the fire is detected, the calculation of the fire distance to a blind person was completed using a pinhole model. This research used 35 data videos with a resolution of 480x640 pixels. The results showed that the fire detection system and the distance estimation achieved an accuracy of 88.86% and the MSE of 0.0358, respectively.

Abstract:

This article deals with the question of the applicability of Lewis’ concept of the culture of poverty to the situation of the socially excluded localities in urban setting inhabited by Roma (“Roma ghettoes”). The “Roma ghettoes” are shown to be places of a specific cultural pattern which emerged in the process of reaction and adaptation to the long-lasting poverty of its inhabitants. This pattern matches most of the parameters of the culture of poverty - with the exception of an elaborated system of kinship. An analysis of its role in “Roma ghettoes,” however, shows that the complex system of kinship does not prevent poverty, but may re/produce it.

Abstract:

The article is focused on the problem of teaching blind elementary schoolers in literary reading lessons in elementary school. The relevance of the topic is due to the need to bring into compliance the content of the education of children with severe visual impairments with the requirements of the Federal State Educational Standards for blind students (option 3.2). At the present time, teachers of schools for blind children continue to experience difficulties in adapting the content of education in this subject. The aim of the article is to analyze and summarize the existing typhlopedagogical experience of teaching this group of children and to determine the directions for adapting the content of teaching literary reading to blind elementary students. Methods used in this study include analysis, description, and comparison. An analysis of the typhlopedagogical heritage suggests that teaching reading to blind elementary schoolers has a number of peculiarities due to the negative impact of visual impairment on their speech and cognitive development, motivation for activity; this can be overcome by adapting the content of education. In their turn, the directions of adaptation can be reached by adjusting the contents of textbooks, enriching the children’s sensory experience, developing their speech and thinking, and using a differentiated approach in teaching by redistributing educational material and developing assessment criteria that are appropriate for the blind students’ needs. The results of this study have important meaning for employees of schools for visually impaired children because they allow to implement a differentiated approach in teaching and to adapt the contents of the Literary reading school subject according to the special educational requirements of children.

Abstract:

If conceptual retrieval is partially based on the simulation of sensorimotor experience, people with a different sensorimotor experience, such as congenitally blind people, should retrieve concepts in a different way. However, studies investigating the neural basis of several conceptual domains (e.g., actions, objects, places) have shown a very limited impact of early visual deprivation. We approached this problem by investigating brain regions that encode the perceptual similarity of action and color concepts evoked by spoken words in sighted and congenitally blind people. At first, and in line with previous findings, a contrast between action and color concepts (independently of their perceptual similarity) revealed similar activations in sighted and blind people for action concepts and partially different activations for color concepts, but outside visual areas. On the other hand, adaptation analyses based on subjective ratings of perceptual similarity showed compelling differences across groups. Perceptually similar colors and actions induced adaptation in the posterior occipital cortex of sighted people only, overlapping with regions known to represent low-level visual features of those perceptual domains. Early-blind people instead showed a stronger adaptation for perceptually similar concepts in temporal regions, arguably indexing higher reliance on a lexical-semantic code to represent perceptual knowledge. Overall, our results show that visual deprivation does changes the neural bases of conceptual retrieval, but mostly at specific levels of representation supporting perceptual similarity discrimination, reconciling apparently contrasting findings in the field.

Abstract:

Mobile communications, not infrequently, are disrupted by multipath propagation in the wireless channel. In this context, this paper proposes a new blind concurrent equalization approach that combines a Phase Transmittance Radial Basis Function Neural Network (PTRBFNN) and the classic Constant Modulus Algorithm (CMA) in a concurrent architecture, with a Fuzzy Controller (FC) responsible for adapting the PTRBFNN and CMA step sizes. Differently from the Neural Network (NN) based equalizers present in literature, the proposed Fuzzy Controller Concurrent Neural Network Equalizer (FC-CNNE) is a completely self-taught concurrent architecture that does not need any training. The Fuzzy Controller inputs are based on the estimated mean squared error of the equalization process and on its variation in time. The proposed solution has been evaluated over standard multipath VHF/UHF channels defined by the International Telecommunication Union. Results show that the FC-CNNE is able to achieve lower residual steady-state MSE value and/or faster convergence rate and consequently lower Bit Error Rate (BER) when compared to Constant Modulus Algorithm-Phase Transmittance Radial Basis Function Neural Network (CMA-PTRBFNN) equalizer.

Abstract:

Visually impaired children within aged of 7–8 years old often face problems dealing with the adaptation in the environment. They have very low social skill and turn into dependence on their parents. Further, they need developing their self-confidence towards social skills. Mobility orientation, learning was one of the learning strategies that aimed to improve their social behavior in the environment. The purpose of this study was to develop the social skills of blind children in interacting with the environment and peers. This study involved a single subject research method (SSR) with A-B-A design. The subject of the study consisted of 3 blind children within 7–8 years old. The results showed that there was a significant improving in their social skills and independence during their daily lives. The female children tended to have some difficulties during the school activities compare with the male children. The family’s involvement is important to be used for helping them during the learning adaptation process with the environment. In short, the social skill development really matters for the blind children as they can imagine what kind of places where they are.

Abstract:

Purpose: This paper reviews the studies on balance in the blind. Methods: The paper comprehensively reviewed studies on balance in the blind from the following databases: PubMed, MEDLINE, Web of Science, ScienceDirect, Cochrane Central Register of Controlled Clinical Trials, Google Scholar, and Scopus, from 2001 to 2019. Also, other available papers were examined. Results: Out of 35 evaluated studies, 32 articles were fully represented and the rest were only summarized. These articles covered two issues: 1) balance adaptation in the blind, 2) the effects of training protocols on the balance in the blind. Conclusion: The blind suffer from poor balance. However, they tend not to differ from normal people, when sufficient data from the vestibular and proprioception systems are available. Also, balance in the blind improves by age, which increases the efficiency and maturity of vestibular and proprioception systems. The blind tend to be more reliant on the hip than ankle strategy. All the training protocols reviewed in this paper have positively affected balance in the blind. Nevertheless, it was impossible to determine the most efficient protocol, and further qualitative studies are required for this purpose.

Abstract:

Reaching movements made to visual targets in a rotating room are initially deviated in path and endpoint in the direction of transient Coriolis forces generated by the motion of the arm relative to the rotating environment. With additional reaches, movements become progressively straighter and more accurate. Such adaptation can occur even in the absence of visual feedback about movement progression or terminus. Here we examined whether congenitally blind and sighted subjects without visual feedback would demonstrate adaptation to Coriolis forces when they pointed to a haptically specified target location. Subjects were tested pre-, per-, and postrotation at 10 rpm counterclockwise. Reaching to straight ahead targets prerotation, both groups exhibited slightly curved paths. Per-rotation, both groups showed large initial deviations of movement path and curvature but within 12 reaches on average had returned to prerotation curvature levels and endpoints. Postrotation, both groups showed mirror image patterns of curvature and endpoint to the per-rotation pattern. The groups did not differ significantly on any of the performance measures. These results provide compelling evidence that motor adaptation to Coriolis perturbations can be achieved on the basis of proprioceptive, somatosensory, and motor information in the complete absence of visual experience.

Abstract:

This paper considers and proposes an innovated method of structure criterion switching control for the self-optimized blind decision feedback equalizer (DFE) scheme which operates by switching between adaptation modes according to the mean square error (MSE) convergence state. The new switching control shortens the blind acquisition period time of the DFE and, consequently, speeds up its effective convergence rate. The switching control is based on the variable switching threshold which combines the commonly used MSE estimate of the DFE?s output and a posteriori error of the all-pole whitener performing front-end amplitude equalization during the blind operation mode. The efficiency of the DFE switching control is verified by simulations of single-carrier system transmitting QAM signals over multipath channels.

Abstract:

For the first time in the latest Assessment Report of the Intergovernmental Panel on Climate Change (IPCC), water has been the focus of dedicated chapters in both Working Group 1 (Chapter 8) and 2 (Chapter 4). Nevertheless, we argue here that water has not yet received the full attention it deserves from both scientists and policymakers for several reasons. Firstly, the historical focus on temperature change has been further increased with the use of global warming levels motivated by an aim to be consistent with current policy framings. Secondly, an increasing attention paid to extreme weather has sometimes overshadowed longer time-scale changes such as the aridification of an increasing fraction of arable land and the increasing variability of the water cycle from month to month, season to season, and year to year that also yield cascading impacts on all water use sectors. Thirdly, a stronger focus is needed on understanding the effectiveness of current and future adaptation strategies in reducing water-related climate risks. Finally, the role of water has not been adequately recognized in the assessment of mitigation strategies although the compliance with the Paris Agreement and the current pledges all require a massive deployment of land-based strategies whose feasibility and efficiency heavily depend on water resources. It is thus essential to develop a more integrated approach to water and climate change, that would allow scientists and policymakers to “close the loop” between mitigation options, water cycle changes, hydrological impacts and adaptation.

Abstract:

This paper addresses the problem of blind separation of non-stationary signals. We introduce an on-line separating algorithm for estimation of independent source signals using the assumption of non-stationary of sources. As a separating model, we apply a self-organizing neural network with lateral connections, and define a contrast function based on correlation of the network outputs. A separating algorithm for adaptation of the network weights is derived using the state-space model of the network dynamics, and the extended Kalman filter. Simulation results obtained in blind separation of artificial and real-world signals from their artificial mixtures have shown that separating algorithm based on the extended Kalman filter outperforms stochastic gradient based algorithm both in convergence speed and estimation accuracy.

Abstract:

High phase noise and low phase noise have been consideration in CO-OFDM systems, respectively. The hybrid mitigation algorithm is optimized to approach to high phase noise and low phase noise environment, and a hybrid half-blind phase noise compensation algorithm is proposed, which could be suitable to shifty DFB laser linewidth. 4QAM and 16QAM are used to modulate binary signal. The new proposed phase noise compensation algorithm is considered a mitigation method which has the ability of half-blind self-adaptation. It deduces the coefficient matrix in high and low phase noise compensation matrix and could improve performance under high or low modulation index situation.

Abstract:

ObjectiveThis study aimed to assess the feasibility of a low-literacy adaptation of the Alzheimer’s Disease Assessment Scale – Cognitive (ADAS-Cog) for use in rural sub-Saharan Africa (SSA) for interventional studies in dementia. No such adaptations currently exist.MethodsTanzanian and Nigerian health professionals adapted the ADAS-Cog by consensus. Validation took place in a cross-sectional sample of 34 rural-dwelling older adults with mild/moderate dementia alongside 32 non-demented controls in Tanzania. Participants were oversampled for lower educational level. Inter-rater reliability was conducted by two trained raters in 22 older adults (13 with dementia) from the same population. Assessors were blind to diagnostic group.ResultsMedian ADAS-Cog scores were 28.75 (interquartile range (IQR), 22.96–35.54) in mild/moderate dementia and 12.75 (IQR 9.08–16.16) in controls. The area under the receiver operating characteristic curve (AUC) was 0.973 (95% confidence interval (CI) 0.936–1.00) for dementia. Internal consistency was high (Cronbach’s α 0.884) and inter-rater reliability was excellent (intra-class correlation coefficient 0.905, 95% CI 0.804–0.964).ConclusionThe low-literacy adaptation of the ADAS-Cog had good psychometric properties in this setting. Further evaluation in similar settings is required.

Abstract:

The paper describes several processes of adaptation in work with both congenitally and adventitiously blind persons. The authors discuss imagery in terms of helping the client make psychosocial changes necessary to improve mental attitudes and to return to the mainstream. Two basic types of imagery are presented: 1) voluntary imagery—a conscious process, and 2) involuntary imagery, occurring spontaneously.

Abstract:

Abstract The purpose of the study is to assess the search for mainstreaming climate change adaptation into regional planning of least developed countries (LDCs) and draw strategy implications for regions in Bangladesh. The findings of the study revealed that national adaptation programme of action (NAPAs) in least developed countries were being gender-blind and failed to be properly implemented. Least developed countries should therefore do more to prepare for ongoing and future climate changes focusing on actions that are no-regrets, multi-sectoral and multi-level, and that improve the management of current climate variability. Strengthening capacities to use climate information, enabling locally appropriate responses, screening climate risks, assessing risks and adaptation options, starting with existing policies and plans, broadening constituencies beyond environment agencies, managing strategy conflicts, learning from projects and recognizing their limitations, monitoring and learning are the foreseen strategic actions by regions in Bangladesh for effective mainstreaming of climate change adaptation into regional development planning in the years to come.

Abstract:

Phreatoicidea Stebbing, 1893 live in freshwaters of Gondwana: Australia, South Africa, India and New Zealand. Many of these isopods have a subterranean lifestyle. Parsimony analysis of morphological data of generic exemplars and a Triassic fossil was used to explore the timing of this habitat adaption. The monophyly of the Hypsimetopidae Nicholls, 1943, including blind taxa Hyperoedesipus Nicholls & Milner, 1923 (Western Australia), Nichollsia Chopra and Tiwari, 1950 (Ganges Plain, India) and Phreatoicoides Sayce, 1900 (Tasmania and Victoria) was strongly supported. Crenisopus Wilson and Keable, 1999 (Kimberleys, Western Australia) and the PonderellidaeWilson & Keable, 2004 (Queensland mound springs) may be sister to hypsimetopids. Blind Phreatoicidae found only in south-eastern Australia and in New Zealand were also monophyletic. The hypogean habitat, blindness, fossil and plate tectonic evidence were mapped on the cladogram to estimate timing of this adaptation. A subterranean adaptation before 130 million years ago was supported for hypsimetopids. Phreatoicus Chilton, 1891 and Neophreatoicus Nicholls, 1944 (hypogean in New Zealand) were in a monophyletic clade with epigean Phreatoicidae, Crenoicus Nicholls, 1944 (south-eastern Australia) and Notamphisopus Nicholls, 1943 (New Zealand). Blindness in epigean taxa is consistent with recolonisation of surface waters from underground refuges. Because Crenoicus is sister-group to the New Zealand clade, and because overseas dispersal between Australia and New Zealand is unlikely, the minimum age for these blind phreatoicids is ~80 million years. This evidence is consistent with a subterranean freshwater fauna surviving the presumed Oligocene inundation of New Zealand.

Abstract:

I suggest that the transformation of an artifact from an introductory-type instrument into a viable, collectively used tool cannot be understood solely in terms of gradual adaptation of the technology and user environment, but also as a qualitatively broader integration process in which an expansion takes place. The case illustrated a constrained shift of an artifact from its first adopter, an individual pioneer user, to a more collective user in institutional medicine. The artifact, a neuromagnetometer instrument for brain research and diagnostics, brings together physicists, neuroscientists, physicians as well as various practitioners from the medical imaging industry. I applied an activity-theoretical framework for analysing the adoption of the neuromagnetometer from the pioneer phase of implementation into the more established use. The case showed that the anticipated transformation of the artifact constituted a major challenge for the user organization and its practitioners. It is suggested that an expansion of the object into a shared object of implementation among the separate practitioner groups is indispensable.This expansion of the object involves for the practitioners to recognize both the different objects and requirements of the pioneer phase of the implementation and the new phase of introduction into medical practice. It is shown that this recognition does not, however, come as given, spontaneously born in the transition. The emerging new object may remain only partially shared if not made visible by deliberate effort among the practitioners. The expansion requires collective visualization of the work and reflective dialogue on it. Employing analytical tools, such as the activity-theoretical concepts used here, is one possible way of facilitating such an effort.

Abstract:

This paper introduces an Independent Component Analysis (ICA) approach to the separation of nonlinear mixtures in the complex domain. Source separation is performed by a complex INFOMAX approach. The neural network which realizes the separation employs the so called "Mirror Model" and is based on adaptive activation functions, whose shape is properly modified during learning. Nonlinear functions involved in the processing of complex signals are realized by pairs of spline neurons called "splitting functions", working on the real and the imaginary part of the signal respectively. Theoretical proof of existence and uniqueness of the solution under proper assumptions is also provided. In particular a simple adaptation algorithm is derived and some experimental results that demonstrate the effectiveness of the proposed solution are shown.

Abstract:

The article describes the problem of social and cultural adaptation and pedagogical support of continuous personal development of visually impaired (blind) people. There is a brief overview of the various aspects of this problem. The article emphasizes the urgency of creating an accessible environment for these groups of people with disabilities. It describes the psychological and pedagogical regularities underlying the design environment of personal development and important components of the environment (stimuli, procedure opportunities, developing content and communication activities), providing a process of continuously increasing the subjective status of a person in the course of its life. The article characterizes special feature of adaptation and rehabilitation of persons with disabilities who lost their sight in the later stages of ontogenesis. Authors identify the features of perception of its surroundings, typical of this group of disabled people emotional distress and special needs. They determine the need for psychological support and aid the visually impaired (blind) people with different subjective status. The authors find the solution of the stated problem of expansion of borders available for the visually impaired (blind) people environment the authors are looking for in tourism. They propose to develop for the visually impaired special kind of tour – audio tours, allowing you to recreate the sound atmosphere of the knowledge of new places and cultural attractions. The article discusses quality differences of the audio guide and audio guide. The authors provide recommendations for the design of audio tours for the visually impaired (blind) people. In addition, they propose the algorithm of the technology of creation of the audio guide consisting of five steps. They list the necessary conditions for the design of audio tours: composition required for the project implementation specialists and logistics support. The article emphasizes the social importance of the activities on the creation of audio tours for healthy people.
