Abstract
Supply chain Integration importance leads to this believe that some scholars express that the whole concept of supply chain management is derived from integration. Providing the basis for creation and effective continuation of supply chain management requires the recognition of main factors affecting the integration. Studies reveal that the organizations with higher levels of social capital are more successful than their rivals. So, the purpose of this study is to surveying Social Capital Influence on Supply Chain Integration. Considering the purpose, this study is applied research, and based on its research methodology, it is a correlation descriptive, and it is specifically based on the structural equation models. The population consisted of 435 organizations in food industry of Fars province in Iran, and via employing stratified sampling, 124 executives related to supply chain management were selected and the questionnaires were distributed and collected data were analyzed. This model suggests that five factors influence Supply Chain Integration, and the purpose of the research was to investigate the influence of social capital on these factors. The results indicated that the social capital has positive and direct relation with integration, communication pattern, trust and commitment and has no direct relation with power and attitude.

Abstract
One of the main concerns that many countries of the world are encountering, is some economic activities which are usually hidden from official view. Activities such as exchanging stolen goods, drug trafficking, corruption, gambling, smuggling, are among illegal activities, and others like refusing to report the incomes, fringe benefits, and cash discounts for the staff are among the legal activities of shadow economy. A considerable part of economic literature during the past decade focused on the research findings concering the ways of measuring, defining, and determing the extense of shadow economy in the world. Using the “Structural Equation Modeling” and some literature-specified causes and indicators we aim to reach the case study of Iran. Estimation of size and evolution of Iranian shadow economy is analyzed through “Dynamic Multiple Indicators-Multiple Causes” which is one of the most important indirect techniques available. The advantage of this model is evaluation of the simultaneous impacts of all variables on each other, and has fewer restrictions compered to other models. The research findings reveal the increasing trend of shadow economy in Iran and acts as an alarm for policy makers and authorities.

Abstract
Over the past decades, Enterprise Resource Planning systems (ERP) have become one of the most important developments in the use of information technology. ERP implementation projects which involve large groups of organization's resources are usually large and complex. There are evidences of high failure in ERP projects. Therefore, attention to ERP system success or failure factors is critical. Governance is one of factors that had been considered as influencing factors of ERP success in some researches, so this study intends to investigate direct relation between IT governance practice and ERP system success. This paper used an adapted model from the widely used Delone and McLean's model of IS success for assessing ERP value. With considering the relationship between governance aspects and the variable of adopted IS success model, the conceptual model and assumptions of this study were developed. Data gathered by questionnaire and based on responses from MAPNA group companies' members. Then structural equation modeling and Smart PLS software were used for analyzing survey data. According to obtained results, governance has a substantial relation with ERP system success.

Abstract
Aims The defect in the protection, conservation, maintenance, solidification, and restoration of historic brick buildings of Iran is a performance failure indicator in preserving the authenticity of Iranian architectural heritage in structural interventions. The aim of this study was to decode the seismic stability model of historic brick buildings of Iran.
Instruments & Methods The present descriptive research with survey method was conducted on the community of valuable and stable Iranian historic monuments; 36 cases were selected by judgmental non-random sampling method. A researcher-made questionnaire was used to determine the technical and engineering qualities of the buildings structures. Initially, a design model was developed and, then, modified with experimental data and path analysis aid. The data were analyzed by SPSS 19 software, using exploratory factor analysis and the varimax method in Kaiser standardization and AMOS 15 software with structural equation modeling (SEM) and absolute fit, adaptive fit, parsimonious fit, and regression.
Findings Three main high-value factors of 37.19%, 36.95%, and 22.07%, were found with the names of earthquake damage marvelous, affordability of direct seismicity, and indirect seismicity. There was a significant relationship between the destruction potentiality and tremor with the affordability of seismicity resistance of the monuments. Destruction and tremor potentiality had a significant effect on affordability and indirect resistance of seismicity. Conclusion The seismic stability model of historic brick buildings of Iran is confirmed, in such a way that with the proliferation of destruction potentiality or tremor, the seismic destruction of the buildings is intensified and with the development of direct resistance to earthquakes, the seismic stability of the buildings is intensified. Increasing indirect resistance and, in fact, the dimensional proportions factor, as an intervention, increases seismic stability of the buildings.

Abstract
The diversity of the skills required in project management and the demand for learning them as one of the main sources of competitive advantage in organizations is growing. One of the ways to learn project management capabilities is through other organizations and people. Inter-organizational learning is the way in which different organizations in an alliance collaborate, share knowledge, and learn from one another. This research focuses mainly on project management capabilities inter-organizational learning process and also on factors affecting it. By using explorative studies, a theoretical model for project management capabilities inter-organizational learning is developed and research hypotheses are formulated based on this model. The data collected from 34 organizational units responsible for different project management functions in two international consortiums of Iran petroleum industry is analyzed and then by using the structural equation modeling, the relationships between research variables are tested. Fitting indices of the model and impact factors between variables resulted from data analysis mostly shows acceptable fit and very strong relationship between components of the model. Finally, suggestions to be used by project based organizations as well as suggestions for future studies are presented along with research results.

Abstract
This survey-study carried out among 360 randomly selected farmers living in drought-prone areas of Fars Province, Iran, set out to investigate the perceptions and psychologi-cal coping strategies of farmers when facing drought. Results showed that farmers per-ceived drought as a threat to all of their resources (material, conditions, personal, social and energies) and used emotion-focused and reactive problem-focused coping strategies rather than problem-focused strategies that require planning and being innovative to counteract its psychological consequences. Using structural equations modeling (SEM), relationships between perceived resource loss and the way farmers cope with drought were tested. Problem-focused coping was predicted by a greater loss of objects (e.g., yield, work utilities, land) and personal resources (e.g. motivation, patience and self-efficacy), but a smaller loss of energies (e.g. time and money). Predictors of emotion-focused coping were a greater loss of objects and energies, but smaller losses of condition and personal resources. The implications for educational interventions are discussed.

Abstract
Aims: With the new COVID-19, a global effort has been made to control and prevent the spread of the disease. Self-care behavior is known to be an effective way to prevent COVID 19. Physical distancing, hand washing are important examples of self-care actions. This study aimed to model and determine the predictors of self-care behavior about the new COVID-19.
Instrument & Methods: Cross-sectional correlational design was used for this study. This study was performed on 1083 people in Kerman Province, Iran, using the available sampling method. The data collection tool was a researcher-made questionnaire based on the main constructs of the Health Belief Model and constructs derived from the review of the literature. Data analysis was conducted using SPSS 22 and AMOS 18 software.
Findings: The mean age of the participants was 32.36±9.34, with an age range of 10 to 65 years. The model explained 72% of the variance in self-care behaviors. The SEM showed that self-efficacy (β=0.685; SE=0.097; p=0.001), perceived severity (β=0.419; SE=0.064; p=0.001), perceived benefits (β=0.288; SE=0.061; p=0.001), health importance (β=0.19; SE=0.063; p=0.001) and knowledge (β=0.248; SE=0.025; p=0.001) were positively and significantly related and perceived barriers (β=0.199, SE=0.046, p=0.001) was negatively and significantly related to self-care behaviors.
Conclusion: Constructs of self-efficacy, perceived severity, perceived benefits, perceived barriers, health importance, and knowledge are the main predictors of self-care and preventive behaviors associated with the novel coronavirus. Therefore, this model can promote self-care programs and predict the incidence and mortality of COVID-19.

Abstract
In this article, after defining a conceptional framework for defining and measuring shadow economy in Iran a close attention is also paid to a more precise definition of shadow economy itself. It is also tried to estimate it's changing process and size during 1975-2007 based on the new definition. Direct and indirect approaches are also briefly discussed to estimate the shadow economy. Then, the strengths and weaknesses of each method are pointed out. So far, almost all of the researches carried out in Iran regarding estimation of shadow economy have mainly focused on structural equation modeling approach using Lisrel. Here in this paper for the first time both structural equation modeling software programs of Amos Graphics and Lisrel are applied to estimate the shadow economy in Iran. A comparison of the process and output of both software packages is also done in this research. Finally, in addition to investigating the direct effects of the causal variables, the interactional effects of them on latent variable of the shadow economy are also analyzed.

Abstract
Firms in many industries rely on knowledge generated outside of the firm as an input to their own research and development. The ability to exploit knowledge that exists outside the boundary of the firm is calld Absorptive Capacity. Cohen and Levinthal defined AC as ‘‘the ability of a firm to recognize the value of new and external knowledge, assimilate it, and apply it to commercial ends’’. They argued that AC is an organizational learning concept and the cumulative effect of continuous learning. However, this definition deals primarily with external knowledge. Implicit in the definition is the notion that firms are aware of internal information and have access to it. In some cases, organizations may not be aware or have access to their existing knowledge, especially tacit knowledge that can only be communicated by direct social interaction.Thus, a network of formal and informal communication linkages are necessary for the internal diffusion of new knowledge and technology. We employed a social theory of absorptive capacity and investigated its affect on innovaton and fliexibility in firm. On the other hand, we investigated the effect of intersubjectivity on absorptive capacity . To illustrate the links, the present study tested the hypothesis by structural equation, applied to a large sample (n=619). The results indicated a strong, positive and direct relation among intersubjectivity, absorptive capacity innovation and flexibility.

Abstract
In order to engage students in higher-level thinking, cognitive activation (CA) strategies have been advanced and utilized in mathematics. CA develops when learners are challenged, confronted with conflicts, asked to think and explain clearly on their learning, and realize connections between new and previous content. Extending the theme to English language teaching (ELT), this study investigated Iranian English language teachers’ knowledge and practice of cognitive activation writing strategies (CAWS). In so doing, a model was proposed based on a questionnaire that was developed and validated in the present study. Through this scale, knowledge and practice of CAWS by 213 English as a foreign language (EFL) teachers were explored. During a pilot phase, the reliability of the questionnaire was calculated to be .78 for the knowledge section and .81 for the practice section. Two items in each section were removed after conducting exploratory factor analysis. Ultimately, the confirmatory factor analysis indicated that the proposed model was fit for the data. Five components were confirmed as constituents of CAWS for the knowledge section, and four components were identified for the practice section. The findings revealed that Iranian EFL teachers were already familiar with the CAWS and purportedly practiced them in their writing classes. Using the scale in the process of writing instruction can provide ELT practitioners with a helpful platform for relating to CA strategies and empowers learners to accomplish tasks such as problem-solving in their writing assignments, similar to what is practiced in mathematics.

Abstract
Nowadays, by the daily expansion of service industries, the subjects of service
marketing and service quality have been converted into vital issues for all
organizations. Abundant attempt of organizations in this area is a clear
evidence of this claim. In the past years, organizations have tried to provide
high quality service and better external customer satisfaction through external
marketing concepts and attitudes of external marketing. One of the important
specifications of services is the employees 'direct interactions with customers
and the determinant role of their customer-orientation behaviors in contact
with customers. Therefore, to gain superior service quality thus external
customers ’satisfaction, we should have employees (internal customers) who
are obligor to the company's goals and visions. They should also have
customer-orientation behaviors. Nowadays, with the introducing of internal
marketing concept, the importance of organization's internal customers
(employees) in the success of external marketing plans has become more
obvious. Researches have indicated that there is a close interaction and
relationship between internal and external marketings. According by, the
present research was conducted to identify the effect of internal marketing's
effect on organizational citizenship behaviors and quality of services. The
research methodology was survey - correlation based on the structural equationsmodel. Using conceptual model (path analysis), the obtained results indicated
that internal marketing effect in Great Tehran Gas Company (GTGC) has
increased organizational citizenship behaviors of the employees as well as the
quality of services.
