This article mainly deduces the intellectual pattern existing in schools based on the formal model. Because schools in different educational systems are also created based on a specific intellectual basis. The documentary method is  used to extract the intellectual basis of formal model schools by referring to the texts and sources in the history of management  was done as required documents. which are often published in the form of books and articles in reputable magazines. In order to obtain comprehensive information until theoretical saturation, about 24 documents were examined and analyzed from the texts in order to achieve the goals of the research. Positivist was deduced as its underlying thought pattern based on analyzing information from the common points of the this model with classical management. Finally, the positivisms intellectual pattern has been analyzed regarding ontology, epistemology, and methodology. The research findings showed that in the ontology of positivists, humans create and label the relationships of external objects in the mental structure they already have and are not related to the external world itself. In addition, the positivist approach intends to use the quantitative and experimental methods in humanities studies as in natural sciences for credibility. Finally, specific positivist rationality believes that knowledge is accompanied by experience.

One of the most important aspects of investment is determining the “optimal investment portfolio”. To date, scientific research has been conducted to determine the optimal portfolio with “artificial intelligence” and “Fuzzy logic”. However, we determine the optimal portfolio based on Dynamic Stochastic General Equilibrium (DSGE) model. On the other hand, several factors affect returns, which is one of the most important issues in investment decision-makings, and various models have been developed to analyze the return of “capital” and “other assets”. In this regard, some of the most important models include linear and non-linear models, artificial neural network models, Fama–French model, Generalized AutoRegressive Conditional Heteroskedasticity (GARCH) model, and optimal stable model. All of these models are indicative of the use of quantitative methods and models in the investment industry. One of the causes of using these models is developing the financial economy. In fact, the development of financial economy has more increased with the concept of “portfolio optimization”. In fact, the portfolio optimization and diversification concept is the basis of developing and expanding classical finance and financial decision-making. Financial markets, especially the capital market, can have a great deal of relevance to other sectors of the economy. In the present study, we design and calibrate a new Keynesian DSGE model in relation to the optimal investment portfolio and effectiveness of shocks (e.g., productivity and foreign exchange earnings fluctuation) on macroeconomics variables.

The Supply Chain Network Design (SCND) with perishability is an active research topic. The Agri-fresh Food Supply Chain (AFSC) is a relevant topic to SCND and this study aims to model a new AFSC for a real-world case study. Regarding the traditional AFSC, the geographically dispersed small farmers transport their product individually to market for selling. This leads to a higher transportation cost, which is the major cause of farmers’ low profitability. This paper formulates a traditional product movement model to represent the existing AFSC. The concept of sharing economic approach is employed by the aggregate and collaborative transportation of products to minimize transportation inefficiency. This paper proposes an aggregate product movement with the vehicle routing model to re-design an AFSC for a case study in Iran based on the data of ETKA Company-the largest domestic agri-fresh food supply chain. A four-echelon, multi-period, Mixed Integer Non-Linear Programming (MINLP) approach for the proposed location-inventory-routing model is formulated for perishable products via considering the clustering of farmers to minimize the total distribution cost.

Price return and P/E are two interesting factors for a lot of investors; The Bohmian quantum mechanics used referring to the time correlation of return and P/E of the stock market under consideration. In this study, we extend the quantum potential concept to determine the behaviour of P/E and also price return in two different industry of Tehran stock market during a time interval of April. 2008 to march 2019. The obtained results show that the quantum potential behaves in the same manner for P/E and price return, also confines the variations of the P/E and price return into a specific domain. Furthermore, a joint quantum potential as a function of return and P/E is derived by the probability distribution function (PDF) constructed by the real data of a given market. It serves as a suitable instrument to investigate the relationship between these variables. The resultant PDF and the corresponding joint quantum potential illustrate that where we have light points in joint quantum potential chart, the probability of those amount of P/E and price return are more than other points. In addition, because of the rectangular shape of the joint quantum potential chart we can say that these two variables behave as two independent variables in the Market.

The present article investigates Emily Dickinson's poem "I taste a liquor never brewed" and aims to solve the confusion of scholars that struggled to specify the precise meaning of some of the terms in the text and fully appreciate the psychic dynamics of it in terms of Lacanian psychoanalysis. The first question the article asks is how is 'desire' represented, and the second is whether the speaker of the poem longs for an 'Other jouissance.' In Seminar XX, Lacan defines Other jouissance as the most intense and ineffable kind and equals it to the jouissance of the mystics. Desire, in Lacanian teachings, is unattainable and an inevitable consequence of language. The famous Lacanian maxims "desire is the desire of the Other," and the "Other is the treasure trove of signifiers" indicate that desire could be represented through signifiers. The article integrates These Lacanian notions in Paul Ricoeur's three-staged hermeneutic Arc, which consists of 1) explanation, 2) understanding, and 3) appropriation. The poem will undergo these three stages of interpretation. By the end of the last stage, the world of the text is appropriated by the selected Lacanian notions. The results of the study are the following: 1) the poem is unique in displaying what Lacan termed 'Other jouissance,' 2) it demonstrates an intense desire for a supreme being—the Other, 3) desire is explicitly named in the poem: it is manifested explicitly in the words ‘liquor," tankards," Alcohol," inebriate," debauchee," drams," drink," little tippler.'

This study seeks to explore the effectiveness of flipped instruction on the Iranian intermediate English as a Foreign Language (EFL) learners reading comprehension and grammar learning. As the participants of the study, 60 Iranian intermediate EFL learners from a language institute in Kerman, Iran, were recruited based on convenience sampling in the form of two intact classes. Then, to conduct randomization, the two classes were randomly assigned to two groups namely, flipping group and control group. Next, the two groups were exposed to 14 treatment sessions in which reading comprehension and grammar were taught to the flipping group through explicit flipped instruction and to the control group through non-flipped mainstream instruction used in the institute. Data collection tools employed in the study included the Quick Placement Test (QPT), Michigan test of grammar, Michigan test of reading, and SPSS 21 software. The results revealed the significant effectiveness of flipped instruction on the Iranian intermediate EFL learners' reading comprehension and grammar learning. Accordingly, it is suggested that EFL teachers use flipped instruction if they seek to enhance EFL learners' reading comprehension and grammatical knowledge.
