The present study is an attempt to problematize the multivalent data in the cyberspace through the lenses of Wittgenstein’s analytic philosophy of language. Adopting this linguistic philosophy approach is aimed at exploring the dichotomous question of whether cyberspace is a possibility for social power or it is a contributory cause of communicative discontinuity and henceforth a possibility for social anomia. The central argument here is that within cyberspace there exist three languages at work each one with a degree of semiotic power: pictorial, verbal and mathematical. Since none of them is based on a one-to-one correspondence between the signifiers and the signifieds, the cyberspace users in practice are led to misinformation and disinformation instead of information. This situation creates an epistemic chasm in their real life. This is because their finite mind is not able to grasp the infinite reality of the cyberspace multivalent data. Accordingly, cyberspace with its abundance of misinformation and disinformation leads us to a mental disorder. This constitutes the real power of social media in creating a socio-political turmoil and anomia.

Purpose: The aim of this study was to design a talent management model for primary school principals in Zanjan. Methodology: The method of the present study was a combination (qualitative and quantitative) and in terms of purpose it was an applied research. The statistical population of the qualitative section was experts who were theoretically familiar with the concept of talent management and based on purposive sampling, 17 of them were interviewed until theoretical saturation. The statistical population in the quantitative part was all primary school principals in Zanjan province (1079 people) in the academic year 2018-19 that according to Krejcie and Morgan table, 283 people were selected by stratified random sampling method. Qualitative research tools were interviews and in the quantitative part, a researcher-made questionnaire was developed based on qualitative results. The validity of qualitative results was obtained by reviewing the codings and using the agreement coefficient between the coders and for the questionnaire with face validity and reliability by Cronbach's alpha test (0.88). For the analysis of qualitative data, the method of basic theory and open, axial and selective coding were used, and for a small part of the structural equations in Amos software version 24. Findings: Qualitative data analysis identified 63 concepts and 10 central themes (environmental, cultural, motivational, educational, human resource management, personal characteristics, regulatory, communication, organizational, managerial and structural factors) that the theme Selective research also obtained effective factors on talent management. The results of structural equations also showed that organizational factors with factor load (0.85), educational (0.83) and cultural (0.80) were more important and in general, the proposed model had a good fit. Conclusion: Improving talent management requires attention to various factors that the education system by investing in organizational, educational and cultural factors can help improve the talent management of managers.

Purpose: To compare the production criteria of tactile sensory books from the perspective of production experts Methodology: The method of the present study was combined in terms of applied purpose and qualitative-quantitative in terms of data collection. In the qualitative part, in order to obtain the consensus of experts in the production and publication of tactile sensory books, the Delphi method was used, and in the quantitative part, using a researcher-made questionnaire to the view of production and publishing experts regarding the production of tactile sensory books. Analytical survey form was performed. In the quantitative part, two relative coefficients of content validity and content validity index were used. The content validity index of the researcher-made questionnaire was reported to be higher than 0.79. The reliability of the questionnaire was 0.863 based on Cronbach’s alpha coefficient. Also, for data analysis, descriptive statistics of mean and inferential statistics of "Friedman" were used with the help of SPSS software. Findings: The findings indicate that the four sub-components of tactile capabilities, audience recognition, texture diversity, and form and shape diversity from the technical criterion of producing a tactile book with an average rank of 16 with the highest rank and the two components of natural objects and circulation or numbers with an average rank of 4.81 have the lowest rank. Regarding the production content criterion, the sub-components of attractiveness with the highest rank of 5.76 and the educational aspect of the content of these books from the point of view of production experts with 3.29 has the lowest position. In the criterion of presenting the production of a tactile book, the sub-component of effective and reciprocal communication with the audience has the highest rank with 5.55 and the role of librarian with 3.07 has the lowest rank. Conclusion: by comparing the three main technical criteria, content and presentation of the production of tactile books, the most important criterion with an average rank of 2.67 content criteria was identified which has the most role for production from the perspective of production and publishing experts.
