The pipeline project, Nord Stream 2 (NS2), has been an issue of controversies. Russia and Germany consider the project an economic contract, but the United-States and Eastern European countries have concerns about its geopolitical effects. These disputes have created a divide in Europe and have posed a threat to trans-Atlantic relations. The current research suggests NS2 can influence the strategic balance between great powers in the international system, giving energy leverage to Russia against United-States, and consequently to China by strengthening projects like the Belt and Road Initiative (BRI). Our findings put forward that not only NS2, in case of realization, is a source of American decline, but also the debates on the issue are a sign of American struggling for protecting its precarious international position. By placing Europe in front of the United-States, NS2 could be one component of European strategic autonomy (ESA); meanwhile, it may jeopardize ESA by depending on Europe on Russia. Europe’s solution to gain ESA is to use its leverages such as normative one to manage the situation for outcomes like protecting Europe’s unity and economic interests.

To analyze the relationship between teachers’ freedom and their required pedagogical content knowledge (PCK), I consider emergent curriculum as an extreme end of curricula with a lot of freedom and autonomy for teachers as opposed to a conventional prescribed curriculum in which teachers have less autonomy. In examining teachers’ pedagogical content knowledge from predetermined curriculum toward emergent curriculum, I argue that required PCK is evolving. At the extreme level of teachers’ freedom some substantially new aspects of PCK are needed. One of the most relevant aspects of pedagogical content knowledge for the emergent curriculum curricular knowledge. In emergent curriculum, the teacher acts as a curriculum developer as well, because curriculum is not determined in advance. Curricular knowledge requires teachers to be expert in fields of learning that are not necessary for teachers in other kinds of curriculum. In addition to substantive PCK, teachers of emergent curriculum have to be both philosophers and artists to be qualified enough to make decisions about curricular issues.

Purpose: The purpose of this study was to model social trust based on social intelligence, social identity, and social isolation based on the moderating role of gender and family economic status on secondary school students in Tehran. Methodology: The research method was descriptive correlation based on modeling and structural equations. The statistical population consisted of all high school students in Tehran in the year 2019, from which 495 students were selected by multistage cluster sampling method. Data collection was done based on Social Trust Questionnaire (Dr Safari nia, Sharif 1389, base on Johnson's theory, 1993), Social Intelligence Questionnaire (Ang Ton Teeth, 2008), Social Identity Questionnaire (Dr Safari nia, Roshan 1390, base on Jenkins's theory, 2000) and Social Isolation Questionnaire (Modaresi Yazdi, 2014). Data analysis was done by SPSS19 and PLS-SEM software in two descriptive and inferential sections. Structural equation modeling was used to test the hypotheses. Findings: The results showed that based on the identified dimensions and components, the research model had a good fit. The results also showed that the results of social isolation, social intelligence and social identity had an impact on students' social trust. It should be noted that the social isolation variable has a negative coefficient and social intelligence and social identity have a positive path coefficient. It is therefore concluded that gender has a moderating effect on the coefficients of variable social identity on social trust. The coefficient indicates that social identity in girls has a greater impact on social trust than boys. It should be noted that gender has no moderating role in the relationship between social intelligence and social isolation with social trust. The results also showed that the relationship between social identity, social intelligence and social isolation with social trust in the high and low economic status group was different. Conclusion: Therefore, it is concluded that the economic situation has a moderating effect on the coefficients of the variables of social identity, social intelligence and social isolation on social trust.

Purpose- Rural tourism, in the perspective of developed economies, is considered as a context-based experience that has a broad range of attractions. Also, it can increase the opportunities to provide services to local communities. Thus, their maintenance has become an integral part of the rural economy. In this regard, the study explored the understanding of rural tourism development in Rudbar County, Guilan province. Design/methodology/approach- This study, in terms of goal is applied-developmental, in terms of paradigm is qualitative, and in terms of method is a grounded theory which is based on an inductive approach. The statistical population consisted of two groups of key rural informants and tourists of Rudbar County. Using a purposive sampling, 18 people were selected by snowball method and data were collected applying in-depth and semi-structured interviews, reaching saturation. To analyze the narratives, three stages of open, axial and selective coding method were used. Findings- Findings showed that the vital commodities of rural tourism in Rudbar are the supply of a mixture of tourism approaches such as ecotourism, agrotourism and participatory approaches such as the view of scenic byways. In the elevated villages near Darfak peak, the commodities are long hiking or cycling alongside Sefidrood River as well as heritage areas. Also, in the development of rural tourism in the study area, the categories of products of the destination, space opportunities of the destination, infrastructure of the destination, cultural support and beliefs of the destination, responsible participation of the destination, cultural acceptance of the destination, marketing for the destination, human capital of the destination, employment in the destination were important. The most important category (core category) was known as "tourism product development policy". Research limitations/implications- Lack of proper access to infrastructures such as mobile coverage accessibility, Internet and accommodation opportunities, frequent cut-offs of tap water in some villages for long hours, and access to tourists and key local informants were among the problems in the way of this study. Practical implications- In order to achieve the development of rural tourism, it is suggested that special attention be paid to the development policy of Guilan tourism product supply in different dimensions. Since most of the incoming tourists to Guilan are nature tourists, increasing the village's service such as improving mobile and Internet access, improving the village's water and electricity quality, travel agency offices and active tour operators in the villages, automobile repair shops, local food restaurants and eco-resorts are vital. Originality / Value- A grounded theory systematically examines phenomena in their natural state in the form of regular steps. In this method, generalization is not the purpose. Instead, the goal is to understand the phenomenon and its various dimensions.

One of the goals of the government is to increase the competitiveness of domestic firms to export goods and services. Moreover, the role of exports in many economic sectors has been emphasized. There are two essential requirements for developing non-oil exports: first, the presence of firms in export markets and increasing their competitiveness; second, the survival of them in international markets. This paper assesses the impact of leverage on export survival by using the data of 16 Iranian manufacturing firms from 1999-2018. These companies operate in the agricultural and food industry and are indexed in the stock exchange market. Based on Cox semi-parametric model estimation, the main result is that leverage harms export survival.

Economic justice and equitable distribution of income, along with important issues such as economic growth and development, the reduction of inflation and unemployment, have always been of concern to economists. Fair distribution of income and reduction of income inequality in society, and the identification of factors affecting income inequality to make the right policy are necessary and obvious. The purpose of this paper is to examine the impact of income tax on income distribution in Iran. In this regard, Autoregressive Distributed Lag (ARDL) approach has been used to investigate the existence of a long-run relationship between variables and to estimate the coefficients related to long-run and error correction models for income inequality from 1978 to 2012. The results indicate a long-run relationship among the variables and show that an increase in income tax revenues leads to a reduction in income inequality.
