This study was designed to examine children's ability to learn new information from textual materials. It investigated the extent to which equally intelligent average and poor readers could recognize and recall information from expository texts. Two types of explicit and four types of inferential information were tested through recognition items. Subjects recognized more explicit than inferential information, although some inference types were more difficult than others to recognize. In addition, the study examined the extent to which acquisition of new information was a function of prior knowledge. The probability of a correct response was computed for three different prior knowledge conditions: 1) correct, 2) wrong, or 3) unknown. This permitted investigation of the effect of prior knowledge on subjects' acquisition of new information, as well as subjects' ability to correct old information. Prior knowledge was a powerful factor in reading comprehension for both average and poor readers. Both groups were better at acquiring totally new information than at correcting old information that was inaccurate. Even when prior knowledge was contradicted by the text, subjects used it, rather than textual information, for item recognition. Only when they did not, or believed they did not, possess the necessary prior knowledge did they resort to text—with a consequent improvement in recognition.

Good And Poor Readers

The purpose of this investigation was to compare the question answering of good and poor readers when their prior knowledge for the answers to questions was determined before reading to be accurate, inaccurate, incomplete, or missing. Fifty-six fifth-grade students with equivalent I.Q.'s, but varying in reading ability and extent of general prior knowledge for the passage topics, participated in the study. Subjects read an expository passage written on their approximate instructional reading level. The results indicated that poor readers did not use prior knowledge to the same extent as did good readers. This was especially true when students were learning new information. The results also suggest that poor readers have difficulty answering text implicit questions even if they possess adequate prior knowledge for passage topics.

Although the role of IQ in developmental dyslexia remains ambiguous, the dominant clinical and research approaches rely on a definition of dyslexia that requires reading skill to be significantly below the level expected given an individual’s IQ. In the study reported here, we used functional MRI (fMRI) to examine whether differences in brain activation during phonological processing that are characteristic of dyslexia were similar or dissimilar in children with poor reading ability who had high IQ scores (discrepant readers) and in children with poor reading ability who had low IQ scores (nondiscrepant readers). In two independent samples including a total of 131 children, using univariate and multivariate pattern analyses, we found that discrepant and nondiscrepant poor readers exhibited similar patterns of reduced activation in brain areas such as left parietotemporal and occipitotemporal regions. These results converge with behavioral evidence indicating that, regardless of IQ, poor readers have similar kinds of reading difficulties in relation to phonological processing.

Background. Partnership in this thesis is interpreted as the responsibility of children education which is taken by the members and their activity. The main role of the partners is to organize the environment of preschool education for children to use their prior knowledge and experience to understand new information and meaningful context.Methods. Two questionnaires were included in this research, 191 parents and 199 educators were questioned. Results. Educators and parents generally see the purpose of preschool education institution to stimulate the child’s social and cognitive development (88.9%) and considerably rarely the purpose is related to meeting the natural needs of a child (32.2%). Educators more often than parents thought that it was necessary to strengthen the education of parents in partnership with their children’s education (p < .001). Mutual ambition to collaborate (67.3%), better education of parents (49.2%), the maintenance of permanent connection (41.7%), information exchange (49.7%) and better confidence in each other (45.7%) would be helpful in seeking for more effective cooperation.Conclusions. Only a small percentage of parents understand that preschool education is most important to meet the natural needs of children, create healthy situations for the development of children’s inborn inclinations. Educators are not reoriented enough to the tendencies of nowadays and only one third of them believe in its importance to meet the natural needs of a child. In most cases parents and educators indicated the same factors which might influence empowering of parents and educators for the education cooperation which would develop into to partnership, but the importance of the  factors was often different.Keywords: empowering, cooperation, communication, preschool education, partnership.

This article is devoted to analysis of the modern problems of book publishing in the context of national information space. Development of the Ukrainian state is impossible without development of national book publishing, which is a part of its information space. In Ukraine, as one of the post-Soviet states, the formation of new information and communication system is based on its own information tradition, mentality and features of spiritual culture of the Ukrainians. It plays an important role in shaping culture, spirituality, comprehensive vision and consciousness of the nation. They were and they are a source of knowledge and the most effective way of its transfer. The transience of processes occurring the era of information society, radical socio-economic reforms, sectoral technological revolution requires the continuous scientific researches and analysis, identifying the trends in publishing industry as one of the most important factors in the state’s democratic progress. The author summarizes the development of book publishing of Ukraine and shows its role and place in the modern information society. The study of the modern book publishing is impossible without digression into the past, without finding out the roots of studying of the analysis object. The specific problems of the book industry are identified. It is concluded that in the modern Ukraine the publishing business has intensified, although the positive changes are taking place very slowly: the appropriate economic conditions for development of the publishing industry have not been created, the equipment are outdated; editorial, publishing and printing equipment of domestic manufacture are nonavailable; introduction of advanced technology are low; purchasing ability of the population is low; the sales network of printed products has been destroyed and so on. The businesses are becoming increasingly uneconomical. We propose some measures to improve this situation, strengthening the role of industry in the national information space. The key to improve the situation may be systematic and persistent efforts of the Ukrainian government to support the industry.The reason is that a comprehensive study requires from the performers not only historical knowledge, but also economic, managerial, psychological, political efforts and so on. The most important thing that the society and the state should need is the component of doctrine of information security in the context of the national security

Amid the global discussion on ways to fight misinformation, journalists have been writing stories with graphical representations of data to expose misperceptions and provide readers with more accurate information. Employing an experimental design, this study explored to what extent news stories correcting misperceptions are effective in reducing them when the stories include data visualization and how influential readers’ prior beliefs, issue involvement and prior knowledge may be in that context. The study found that the presence of data visualization in news articles correcting misperceptions significantly enhanced the reduction of misperceptions among news readers with less than average prior knowledge about an issue. In addition, it was found that prior beliefs had a significant effect on news readers’ misperceptions regardless of the presence or absence of data visualization. In this way, this research offers some support for the notion that data visualization may be useful to decrease misperceptions under certain circumstances.

New Information

CK2 is a Ser/Thr protein kinase overexpressed in many cancers. It is usually present in cells as a tetrameric enzyme, composed of two catalytic (α or α’) and two regulatory (β) subunits, but it is active also in its monomeric form, and the specific role of the different isoforms is largely unknown. CK2 phosphorylates several substrates related to the uncontrolled proliferation, motility, and survival of cancer cells. As a consequence, tumor cells are addicted to CK2, relying on its activity more than healthy cells for their life, and exploiting it for developing multiple oncological hallmarks. However, little is known about CK2 contribution to the metabolic rewiring of cancer cells. With this study we aimed at shedding some light on it, especially focusing on the CK2 role in the glycolytic onco-phenotype. By analyzing neuroblastoma and osteosarcoma cell lines depleted of either one (α) or the other (α’) CK2 catalytic subunit, we also aimed at disclosing possible pro-tumor functions which are specific of a CK2 isoform. Our results suggest that both CK2 α and α’ contribute to cell proliferation, survival and tumorigenicity. The analyzed metabolic features disclosed a role of CK2 in tumor metabolism, and suggest prominent functions for CK2 α isoform. Results were also confirmed by CK2 pharmacological inhibition. Overall, our study provides new information on the mechanism of cancer cells addiction to CK2 and on its isoform-specific functions, with fundamental implications for improving future therapeutic strategies based on CK2 targeting.

Effects Of Drought

In recent years, research on spermine (Spm) has turned up a lot of new information about this essential polyamine, especially as it is able to counteract damage from abiotic stresses. Spm has been shown to protect plants from a variety of environmental insults, but whether it can prevent the adverse effects of drought has not yet been reported. Drought stress increases endogenous Spm in plants and exogenous application of Spm improves the plants’ ability to tolerate drought stress. Spm’s role in enhancing antioxidant defense mechanisms, glyoxalase systems, methylglyoxal (MG) detoxification, and creating tolerance for drought-induced oxidative stress is well documented in plants. However, the influences of enzyme activity and osmoregulation on Spm biosynthesis and metabolism are variable. Spm interacts with other molecules like nitric oxide (NO) and phytohormones such as abscisic acid, salicylic acid, brassinosteroids, and ethylene, to coordinate the reactions necessary for developing drought tolerance. This review focuses on the role of Spm in plants under severe drought stress. We have proposed models to explain how Spm interacts with existing defense mechanisms in plants to improve drought tolerance.
