The Principal's Perceptions of School Libraries and Teacher-Librarians
Authors: Hartzell Gary
Published: March 2022

There is no question that principal support is vital to the establishment and maintenance of a quality library media program. The problem is the support flows from trust, and trust flows from understanding. Many principals do not understand what teacher-librarians really do, nor do they appreciate the potential the library media program has for contributing to student and faculty achievement. Principals' perceptions of school libraries and teacher-librarians have been shaped by four interactive forces. The first is their own experiences in school libraries as children, in which they perceived the library as peripheral to the classroom. The second is the effect of their professional training, in which the library's role in curriculum and instruction was consipicuously absent. The third is the nature of the teacher-librarian's work, which is to enable and empower others. The fourth is the low profile teacher-librarians and school libraries have in the professional literature read by teachers and administrators, which prevents them from updating their sense of what the library really is and can do. The cumulative result is that administrators have only a limited and inaccurate understanding of libraries and teacher-librarians. The only way to change principal perceptions is to assault them directly, repeatedly, and from a multiplicity of directions. Reshaping perceptions takes time and effort and commitment. In the meantime, these erroneous perceptions will continue to guide most principals' relationships with school library media specialists.
Instructional Intervention is the Key: Supporting Adolescent Information Seeking
Authors: Branch Jennifer
Published: March 2022

This research sought to examine the information seeking processes employed by Canadian junior high school students from Inuvik, Northwest Territories and Beaumont, Alberta when using CD-ROM encyclopedias and when completing inquiry-based learning activities. The first study revealed that participants needed both instruction and practice to develop the skills and strategies needed for full-text searching of CD-ROM encyclopedias. The participants tended to use search terms only from the original question, had difficulty selecting topics and articles from the retrieved list, and did not read long articles as carefully as short articles. The second study revealed that students needed support throughout the inquiry-based learning experience and that using Kuhlthau's Information Search Process model as a guide for affective stages was useful. Participants needed time to explore, discuss, and read before finding a focus for their inquiry. Both studies found that participants wanted time to talk and discuss and that instruction was important to help students move forward in their searching and learning.

Published: March 2022

O texto apresenta a pesquisa em andamento de estudos sobre Educação de Jovens e Adultos, Comunidade Quilombola, Formação e Mundo do Trabalho no Programa de Mestrado Profissional em Educação de Jovens e Adultos – MPEJA da Universidade do Estado da Bahia - UNEB. A escolha do tema desvelou-se a partir do contato da pesquisadora com a história dessa comunidade a ser investigada, haja vista que nessa perspectiva não há trabalhos acadêmicos voltados para esta comunidade. Compreender o processo histórico e social a que as populações negras foram esquecidas das páginas da história do Brasil, sobretudo quando esta põe em pauta questões que dizem respeito as tensões sociais e étnico-raciais em que as comunidades quilombolas estão constituídas no tocante as condições de vida e os processos de alfabetização e letramento. A pesquisa tem como objetivo geral investigar a relação entre a Educação de Jovens e Adultos e a inserção dessas pessoas da Comunidade Guaxinim no mundo do trabalho. E seus objetivos específicos: Elucidar a Trajetória da Educação de Jovens e Adultos em suas concepções histórica e filosófica; caracterizar a Comunidade Guaxinim em suas diversas acepções; identificar as trajetórias de escolarização dos Jovens e Adultos da comunidade; analisar a relação entre a Educação de Jovens e Adultos e a inserção dos quilombolas no mundo do trabalho. A metodologia é conduzida pela pesquisa aplicada que busca gerar conhecimentos para uma aplicação prática em busca da solução da questão norteadora dessa pesquisa com fins de atingir os objetivos definidos. A técnica tem como base a História Oral (HO) à luz do pensamento de Bom Meihy (1998) e Alberti (2004) que trazem à tona questões da História Oral de Vida e da Tradição Oral pelas falas dos sujeitos que contam suas histórias dos processos de inserção na Educação de Jovens e Adultos e no mundo do trabalho. O desenvolvimento desse trabalho perpassa pelas análises metodológicas ligadas aos estudos sobre memória, oralidade e categorias a serem analisadas tais como: EJA, Comunidade Quilombola, Formação, Mundo do Trabalho. Reflexões que Arroyo (2020) nos proporciona a partir da ideia de: “o direito à memória do indivíduo, das memórias coletivas, da luta pelo trabalho e do combate ao extermínio dos jovens”. Refletir sobre a escolarização de Jovens e Adultos do quilombo estão pautadas sobretudo em marcadores sociais e conflitos étnicos e de escolarização que implicam em confrontos de modelos para a inserção no mercado de trabalho. A comunidade quilombola busca alternativas de sair desta alienação do letramento, mas não encontra apoio de Políticas Públicas É na memória individual que encontramos elementos que testemunham a pertença territorial dessas comunidades, suas formas peculiares de linguagem presentes nas categorias nativas nos seus saberes advindos da observação, leitura e usos do ambiente.

National sports policies exist to regulate the sports system so that all can feel the benefits and no one feels disadvantaged. However, it is not yet known whether the existing policies are transparent and fair, so this quantitative descriptive study was conducted to determine the extent of the perception of sports practitioners regarding the application of the principles of transparency and fairness to national sports policies. With the survey method, 455 sports practitioners were selected through purposive sampling to provide answers through a questionnaire on the google form. The statement comes from the variables of transparency and fairness with asymmetric Likert as the answer choice, which is strongly agree to strongly disagree. The results show that 28.48% of sports practitioners strongly agree and 59.81% choose to agree that the principle of transparency has been applied to sports policy, although there are 11.02% of sports practitioners who disagree and 0.69% strongly disagree. On the other hand, 35.22% of sports practitioners strongly agree and 59.84% agree that the principle of fairness has been applied in the implementation of national sports policies. However, there are 4.84% of sports practitioners who disagree and 0.11% strongly disagree if the principle of fairness has been applied. It can be concluded that the principles of transparency and fairness in national sports policies have been felt by sports practitioners, one of which is through the ease of obtaining information related to sports policies to the distribution of awards and coaching.

Authors: Glizburg V. I.
Published: March 2022

Background. The article examines the factors of the development of mathematical giftedness in the context of distance learning, depending on the choice of computer mathematical packages and digital platforms. Mathematical giftedness is considered as one of the types of special intellectual giftedness associated with mathematical thinking.

The aim. To identify the links between the cognitive structures and types of the mathematical thinking that affect the development of mathematical giftedness, with the specifics of the use of digital resources in distance learning.

Materials and methods. The analysis of the features of distance learning and its influence on the development of mathematical giftedness is performed; a comparative study of the relationship between the child’s productive informational activity and the implemented distance learning tools was carried out; methods of selection of digital resources, different in the presented forms and levels of activity of distance work, which contribute to the development of mathematical giftedness of students, have been investigated.

Results. The following factors were assigned to the development of mathematical giftedness by means of digital resources: the formation of a child’s productive informational activity; implementation of innovative approaches to teaching; implementation of the methodology for the selection of digital resources. It was found that  the  implementation of mathematical abstractions by digital means of visualization improves the quality of assimilation of concepts, forms a stable interest in the subject, and contributes to the development of topological thinking. The work identifies specific psychological problems arising in the process of implementing distance learning mediated by computer technologies, the resolution of which affects the possibility of developing mathematical giftedness, in particular: the problems of emotional saturation and the construction of interpersonal relationships. As specific factors, contributing to the solution of these problems, the following are proposed, in particular: increasing motivation, designing group tasks, special systems of tasks, implemented according to the principle of engagement, the solution of which leads to competition and cooperation. The understanding of mathematical abstractions is facilitated by computer applications that implement technologies for rendering graphic components.

Conclusions. Based on the analysis of cognitive structures and types of mathematical thinking, conclusions are drawn about the specifics of the use of digital resources in the process of distance learning, contributing to the effective development of student’s mathematical giftedness.

Published: March 2022

The article presents a review of literature data in order to study current problems in the diagnosis and surgical treatment of liver echinococcosis. At the present stage of technological progress, it is possible to study the genetic, anatomical and pathophysiological aspects of echinococcosis. The article highlights the advantages and disadvantages of surgical operations performed in patients with echinococcal liver damage. Methods and results of surgical treatment in various clinics are considered. The main surgical directions in the treatment of parasitic liver damage have been determined. These are more radical anatomical and extensive liver resections and minimally invasive, including laparoscopic and robotic techniques. Each of the methods used has its own niche of application and its own limitations. An opinion is expressed about the prospects for the development of minimally invasive methods of surgical treatment. The authors note the actual absence of a unified standardized tactics of surgical treatment at the moment. It is noted that the literature contains only fragmentary data on the possibility of combining minimally invasive and classical methods of surgical treatment. Despite the introduction of new methods of treatment, the percentage of complications and mortality are still high. Thus, the lack of uniform diagnostic standards and principles for determining surgical tactics testifies to the urgency of the problem of treating parasitic liver damage and determines the search for new solutions in order to improve the results of surgical treatment of this pathology.

Published: March 2022

Among patients with floating rib fractures without pneumo- and hemopneumothorax or after their elimination, the most severe disorders of ventilation and circulation occur in patients with multiple bilateral rib fractures and a fracture of the sternum manubrium with the formation of a floating sternocostal segment of the chest. At the same time, the suction aero- and hemodynamic function of the chest is disturbed, there is pressure on the heart and large vessels. As a result, the efficiency of external respiration progressively decreases, the respiratory muscles are exhausted, which requires an urgent transfer to artificial ventilation of the lungs. The article presents a clinical case of successful treatment of such a chest injury using the author’s technique (Patent No. 2621871 of the Russian Federation). The extrathoracic silicone reinforced splint has two horizontal branches that go around the mammary glands. The splint is attached to the floating sternocostal segment with ligatures passed behind the sternum and laterally – to stable sections of the ribs along the posterior axillary line on both sides. The tire reliably holds the sternocostal segment from paradoxical movements. The tire is removed after 3  weeks. By this time, fibrous calluses are formed in places of fractures of bones and cartilage, and the swelling of the chest wall subsides. Superficial bedsores in the places of fixation of the splint are epithelialized under the scab within 7–8 days. The patient was examined a year later, her condition was satisfactory, she had no complaints, there was no chest deformity. The technique is less traumatic, it is indicated for patients with polytrauma and in other cases.

The aim: to conduct a clinical and diagnostic evaluation of the effectiveness of the administration of a complex of drugs in the region of hemolymphocirculation in optical neuropathy in patients with edematous form of endocrine ophthalmopathy.

Materials and methods. The results of diagnosis and treatment of 31 patients (61 eyes) with optical neuropathy on the background of edematous exophthalmos in endocrine ophthalmopathy were analyzed. To identify hidden forms of optical neuropathy, such studies were prescribed as computer microperimetry on a confocal infrared ophthalmoscope, a complex of electroretinographic studies: registration of maximum ERG, oscillatory potentials. Latent forms of optical neuropathy were detected in 22 cases. In 9 cases, there were obvious forms of optical neuropathy. All patients underwent a 10-day course of intensive complex treatment, consisting of injections into the region of hemolymphocirculation (projection of the pterygoid fossa) No. 6–8 (No. 3–4 on each side) with an interval of 24 hours of a drug mixture, the formulation of which included Lidocaine 20 mg, Dexazone 4 mg, Hemase 3000 UNITS, Dalargin 1 mg.

Results. In all patients, there was a pronounced positive dynamics in the form of a significant (from 0.6 to 1.0) increase in visual acuity, a decrease in exophthalmos from (2.0 to 3.0 mm), an increase in color and contrast sensitivity.

Conclusions. Due to the violation of venous and lymphatic outflow due to thickening of extraocular muscles and retrobulbar fiber, injections into the hemolymphocirculation region (projection of the pterygoid fossa) of drugs with a wide range of decongestant and metabolic effects are justified, effective and safe.

Abstract— EMRSA is a tool that can generate electrical energy by utilizing vibration energy that is wasted in a vehicle. Vibration energy includes energy that is wasted on vehicles and is still very rarely used. Therefore, in this study, an experiment was carried out to convert vibration energy into electrical energy. The purpose of this study was to determine the effect of the frequency of spring oscillations on the electric voltage produced by a laboratory-scale regenerative shock absorber. The research was carried out by providing variations in the load on the spring so that a different frequency was obtained in each experiment. The results of the experiment show that the frequency of the spring oscillation is directly proportional to the result of the electric voltage generated. The higher the frequency given, the greater the resultant voltage generated. From the experiments that have been carried out, the results of the electrical voltage of 0.537 volts are obtained at a frequency of 3.37 Hz with a number of copper coils of 500 turns and a copper diameter of 0.1 mm.

Objective Anorexia nervosa (AN) is a disorder with a significantly high prevalence. Affective disorders, including depressive disorder (DD), often coexist with this eating disorder (ED). In this review we will focus on its prevalence, associated vulnerability factors, clinical manifestations, possible etiological factors and its prognosis.Methods A bibliographic search was carried out in the PubMed database selecting those articles that approached the subject of comorbidity between AN and DD. The search was limited to articles published from January 1990 to December 2021.Results Of the 1891 abstracts reviewed, 33 studies met inclusion criteria. The prevalence of this comorbidity was extremely variable between studies, which exposed their heterogeneity. As to symptomatology this comorbidity presents itself with more severity, greater expression of psychological traits and greater cognitive impairment. Certain personality traits are postulated as vulnerability factors. Genetic factors such as neurochemicals seem to be involved in its pathogenesis.Conclusion The comorbidity between DD and ED have important influence in its symptomatic expression, severity and prognosis. Some of the analyzed studies provide consistent data, but there are others that are contradictory. It would be necessary to increase the number of studies and use a unified methodology.

The absence of a ground truth for internal motion in clinical studies has always been a challenge to evaluate developed methods to extract respiratory motion especially during a 60-second cone-beam CT (CBCT) scan in Image-Guided Radiotherapy Treatment (IGRT). The unavailability of a gold standard has led this study to present a methodology to manually track respiratory motion on a clinically acquired CBCT projection data set over a 360° view angle. The tracked signal is then used as a reference to assess the performance of four data-driven methods in respiratory motion extraction, namely: the Amsterdam Shroud (AS), Local Principal Component Analysis (LPCA), Intensity Analysis (IA), and Fourier Transform (FT)-based methods that do not require additional equipment nor protocol to the existing treatment delivery. The assessment using this reference signal includes both quantitative and qualitative analysis. It is found out quantitatively that all four methods managed to extract respiratory signals that are highly correlated with the reference signal, with the LPCA method displaying the highest correlation coefficient value at 0.9108. Furthermore, the normalized root-mean-squared amplitude error of detected peaks and troughs within the signal from the LPCA method is also lowest at 1.6529 % compared to the other methods. This result is further supported by qualitative analysis via visual inspection of each extracted signal plotted with the reference signal on the same axes.

Autism spectrum disorder (ASD) is a mental disorder and the main problem in ASD treatment has no definite cure, and one possible option is to control its symptoms. Conventional ASD assessment using questionnaires may not be accurate and required evaluation of trained experts. Several attempts to use resting-state functional magnetic resonance imaging (fMRI) as an assisting tool combined with a classifier have been reported for ASD detection. Still, researchers barely reach an accuracy of 70% for replicated models with independent datasets. Most of the ASD studies have used functional connectivity and structural measurements and ignored the temporal dynamics features of fMRI data analysis. This study aims to present several convolutional neural networks as tools for ASD detection based on temporal dynamic features classification and improve the ASD prediction results. The sample size is 82 subjects (41 ASD and 41 normal cases) collected from three different sites of Autism Brain Imaging Data Exchange (ABIDE). The default mode network (DMN) regions are selected for blood-oxygen-level-dependent (BOLD) signals extraction. The extracted BOLD signals' time-frequency components are converted to scalogram images and used as input for pre-trained convolutional neural networks for feature extraction such as GoogLenet, DenseNet201, ResNet18, and ResNet101. The extracted features are trained using two classifiers: support vector machine (SVM) and K-nearest neighbours (KNN). The best prediction results are 85.9% accuracy achieved by extracted the features from DenseNet201 network and classified these features by KNN classifier. Comparison with previous studies, has indicated the good potential of the proposed model for diagnosis of ASD cases. From another perspective, the presented method can be applied for analysis of rs-fMRI data on other type of brain disorders.

Under the effects of climate change, especially the increase in rainfall intensity, the landslide has recently made a lot of consequences. Therefore, slope failure forecasting has been viewed as a key task to save human lives and economic losses. In the past, slope monitoring was often carried out manually directly on-site, therefore very difficult to get data continuously for a long time, with a too low temporal frequency that does not permit precise forecast. Recently, applying IoT (Internet of Things) technology in monitoring has begun popular. This technology allows data can be automatically gathered, updated and transmitted via the internet in real-time. This not only permits a more precise forecast but also prompt responses before the failure really happen. This paper introduces an IoT integrated model for forecasting the time of failure based on displacements. The detailed guidelines of theoretical basis, how to install devices and how to collect, process and transmit data are represented, so this would be easy and convenient to apply in practice. A small-scale physical model was made to test the function of the system. The simulation tests indicated good performance.
