Future Contingency has been an old debate between philosophers throughout history. On one hand, Aristotle thinks events of the future happen contingently. On the other hand, Diodorus believes what happens in the future is now determined. Diodorus has presented an argument for determinism based on a few premises. Logicians and philosophers try to avoid determinism by denying the first premise of Diodorus, which is the necessity of the past. However, they only regard a qualified version of this premise based on the medieval argument for determinism while some other philosophers consider this premise in a general way. A new argument shall be presented in this paper for determinism similar to the medieval one based on the general version of the premise which is not rejected by systems which reject the medieval argument. This flaw originates in a few properties of the branching model for time. We shall show what this property is and how it would be possible to resolve the problem this property creates.

The present research identifies and prioritizes the effective organizational structure components using content (theme) analysis and Delphi technique and hierarchical analysis (Case Study of Regional Electric Companies of Iran). The present study is applied  based on purpose and is exploratory-survey based on the nature and method of data collection. The statistical population of this study includes 36 experts selected from Iranian regional electricity companies. They were identified through targeted sampling. To analyze the research data, statistical software MAXQDA2012, SPSS and EXPERT CHOICE were used. Using these statistical software, in order to test research questions, Kendall test have been investigated. In the qualitative phase, we analyzed and interpreted (coding) of concepts expressed by the experts of the regional electricity companies of Iran, including open, axial and selective coding. The Delphi method was then used to localize and screen the indices obtained. In the content (theme) analysis phase, 20 factors were identified and after gathering the experts 'responses in Delphi periods, the members' concordance was assessed through SPSS software and by calculating the Kendall's coefficient of concordance for the questionnaires, and the investigation and concordance among the experts was obtained 81.9%. The results showed that 15 components were agreed upon by the experts. In the final step, the components were prioritized using the hierarchical analysis approach. The results of the hierarchical analysis showed that among the criteria, the complexity criterion was of the highest importance. The next priorities from the experts' point of view are the inhibitor or developer factors and the technology criterion.

La langue persane fait partie des langues dont le groupe consonantique finale de la syllabe CVCC est soumise à certaines contraintes du point de vue de la succession des sons. Le présent article se fixe, comme objectif, d’étudier les emprunts lexicaux qui, dans les groupes consonantiques en position finale, comprennent une consonne labiale non appartenant au persan contemporain mais qui y ont trouvé leur place. Pour ce faire, toutes les syllabes en CVCC ayant une consonne labiale en position de C 1 ou C 2 seront étudiées. Elles seront ensuite comparées en fonction de leur statut (lexique pur ou empreint) dans la langue. Seront ainsi étudiés la fréquence d’occurrence de chaque consonne, tous les ordres possibles de leur apparition ainsi que l’ordre de leur succession. Cette recherche s’inscrit dans le cadre des recherches descriptives et analytiques basées sur des données statistiques. Le dictionnaire Mochiri comprenant 40.000 entrées, a été utilisé comme source principale pour l’extraction des données de cette recherche. L’article est présenté dans le cadre théorique des principes de phonématique et du principe de l’ordre (de la succession) des phonèmes en fonction de leur degré de sonorité. Les résultats de cette recherche montrent que le lexique purement persan a un comportement totalement différent du lexique emprunté en ce qui concerne le type de succession dans le groupe consonantique, l’ordre de la succession sonnante et la sélection du noyau de la syllabe. En persan pur, la consonne /f/ en tant que premier élément constitutif du groupe consonantique et la consonne /m/ en tant que deuxième membre de ce groupe, sont les plus fréquemment employées, parmi les consonnes labiales.

To analyze and evaluate textbooks, researchers have either proposed scales and checklists to be filled by teachers and learners or conducted qualitative investigations of the match between SLA theories and textbook activities. This study, however, employs the microstructural approach of schema theory to scrutinize the reading passages of “Mosaic 1 Reading”. To this end, 17 passages of the textbook were randomly chosen and their constituting words were explored as semantic, syntactic, and parasyntactic schemata. The passages were also analyzed in terms of their readability indices. The results showed that they consist of 3722 schema types, 2979 (80%) of which are semantic in nature. Although the textbook aims at “academic success” at English language “proficiency levels”, it provides no objective definition of what they stand for. In terms of readability, however, the passages vary in difficulty from grade three in primary school to college level. Further, the textbook is discussed in terms of its constituting schemata and suitability to the Iranian context and suggestions are made for future research. The findings of this study have important implications for language teaching, testing and materials development. They show that language proficiency must be defined in terms of schema types and the bulk of class time must be spent on teaching semantic schemata rather than syntactic and parasyntactic ones. Similarly, for testing the reading comprehension of these passages, the number and type of test items must be based on the percentage of semantic and syntactic schema types and subjective criteria such as teachers’ intuition or experience must be avoided both in teaching and testing the comprehension of passages.

The issue of proper career path development is important according to the knowledge management model for employees in many risky businesses in the country, especially since the outbreak of coronavirus and international sanctions against our country, so this study aims to design a model of progress. The career path was based on the knowledge management model in start-up businesses. The statistical population studied in this study consists of 877 people working in new businesses. Statistical sample size 269 people were selected through random sampling method. For statistical analysis, SPSS software version 20 and pls3 were used and the alpha level was considered 05p 05 0.05. The results showed that the value of t in all paths between the research factors is equal to and greater than 2.58. As a result, there is a significant relationship between the main factors and their sub-factors in the conceptual-analytical model of the research and also the results showed that the fit of the general research model is appropriate and strong. In general, it can be said that between the first step of the career path with the second step of the career path, between the second step of the career path with the third step of the career path and between the third step of the career path with the fourth step of the career path of employees There is a direct and significant relationship between start-up business employees in the conceptual-analytical model of career path.
