Due to the of use this indicator, the popular project will be chosen accordingly as a certain amount of gas the... 

Health influencers leveraged social networks to connect with people and society during the Covid-19 crisis. Platforms like Twitter served as suitable channels for disseminating published messages through word-of-mouth communication. In times of crises like Covid-19, individuals and organizations involved in managing the situation harnessed this capability, contingent upon the quantity and quality of word-of-mouth exchanges. During public crises, public polarity and sentiment toward the issue and the maintenance of public morale hold paramount significance. Consequently, crafting messages that garner positive word-of-mouth communication became a focal point for health influencers. In this... 

The digital age and its interlace with the pandemic has led to rapid changes in various institutions, including higher education. One of the factors that changes higher education is the expansion of E-learning and Massive Online Open Courses (MOOCs). Although about 15 years have passed since its creation, the pandemic has expanded the E-learning infrastructure and given it more attention, so that now everyone Confesses the possibility of distance education. On the other hand, although the development of MOOCs platforms and their considerable acceptance has attracted the attention of higher education professors and future researchers in this field, it is not properly considered by the... 

The research is performed to study the process of policy making and policy implementation of initiating student education network (Shaad) as as the first official platform of virtual education in Iran. We want to compare this process with “Kingdon’s multiple stream model”; because shaad initiated shortly after the closure of school’s caused by the outbreak of Covid-19 virus, while in recent years there have been several failed attempts to launch formal e-learning plans. Data were gathered trough semi-structured interviews of experts with shaad founders (11 people), reviewing some of the related documents and news, and unstructured observation by researcher. The findings were coded using... 

The purpose of this study is to find the conflicting assumptions of the main actors in the legislation process of Knowledge-based Act. Collecting and classifying all documents related to this policy process, and based on interviews with main actors involved in this process (with different objectives) and using thematic analysis, we first attempt to classify the main actors involved in the process. Second, we analyze the conflicting paradigms which have led to political conflicts in the process. This analysis helps to improve the policy process of similar acts in future  

In 2014, Iranian government initiated “Salamat” universal insurance program, aiming to provide free health insurance coverage for the uninsured population. Consequently, more than 10 million individuals enrolled in the program, and insurance coverage rose 15 percentage points among the urban population. The purpose of this study is to evaluate the program’s consequences on healthcare utilization and mortality of various age-groups. To this end, we have estimated data on healthcare utilization from the results of “Households Expenditures and Income Survey” for years 2011-2017, and also used the data on the frequency of mortality of each age-group taken from the National Organization for Civil... 

Uncertainty is one of the factors influencing the decision making of economic actors which has a long history in the literature of economics. Given that uncertainty is a mental concept, measuring it has always been a problem. In economic research, the instability caused by uncertainty is often used as an indicator of uncertainty. In this thesis, three indices for economic uncertainty in Iran are introduced: an indicator for macro-level uncertainty using fluctuations in macroeconomic variables, an indicator for micro-level uncertainty using micro-level variables and another indicator called the index of economic policy uncertainty index, Which was made by reviewing the newspapers and opinions... 

This study aims to estimate impact of the energy subsidy reform on households’ head time allocation in rural and urban areas in to 2011 to 2013 by making use of treatment effect particularly dose response function approach. Our main contribution is estimation and calculation of labor supply reaction to the unconditional cash transfer by dose of the subsidy that they received, while the previous works in this literature have used the well know binary variable of being in the exposure of program. To control for the demand determinants which are deriving the labor demand, we include the province level GDP and unemployment rate in the model. Our findings show that the subsidy dose does not have... 

Each National Health System has to choose a combination of health and treatment programs, as the health policy to keep people healthy. As a result of shared resources, the more concentration on treatment, make health program weaker and so thegreater rate of prevalence of diseases and the more burden on treatment programs. At this situation, the problem of lack of ability to pay for health services and products will seriously threaten the health of society. Based on statistics of health status, Iran is going to face this state. So here at this thesis, in order to simulate and study the behaviors of key state variables during the time, the model of national health system developed by system... 

It is proposed, in this research, a methodology for a public sector organization to integrate policy making in human capital development and utilization area. In this case the researcher used system dynamics method for modeling and analyzing the situation, to describe the mechanisms that produce the difficulties in the organization. The researcher mentioned the differences between public sector and profit organization, in designing the main part of the model and also the use of dynamic capability approach in designing human capital development parts of it. The model built in this research, describe the events before and after the 1990s separately, according to the different policy making... 

Iranian Power industry has undergone fundamental changes since deregulation started in 2003. Currently, bulk trade of electricity in the industry is mainly conducted through a day ahead wholesale market, representing over 98 percent of the exchange of electricity within the grid. Although the current market regime is under operation for over 4 years, several political, cultural and operational obstacles have hindered effective evolution of the restructuring process. Low political support from privatization of the industry assets backed by lack of confidence and trust in market economies in general, and low economic incentive of the market players has slowed down formation of an effective... 

Supported by a rich literature in psychology and neuroscience, the dual-process theory of decision making assumes that individuals’ decisions are made through arbitration between habitual and goal-directed processes within their minds. Whereas the goal-directed system makes decisions after deliberating all positive and negative consequences of each feasible choice, the habitual system make choices based on the habits formed in previous experiences. Although the decisions of the goal-directed system are always more optimal that those of the habitual system, but due to that fact that the goal-directed system is slow, effortful and time-consuming, it is sometimes more efficient to make... 

Social learning approach in economic policymaking is introduced against conflict-based approach in the similar context. Helco, 1973 first studied the effects of such a learning in economic policymaking and said ”men collectively wondering what to do… Governments not only ‘power’… they also puzzle.” The important point in studying policymaking through social learning approach is paradigm shifts in peoples’ mental models. In this approach, policies are not only the result of conflict between different interests but also are the output of a learning process. In this research we first assume that social learning has not occurred in policymaking community and that individual learning has... 

Today, estimating housing prices is very important in different societies. The reason for this growing importance can be considered the role of housing in the economic decisions and policies of any society. This estimate is made using the quantitative and qualitative characteristics of each housing and in different ways. In the past, housing prices were estimated using traditional models, but in the present century, due to easier and more access to the Internet and the development of organizations and businesses in this context, which produces a huge amount of data, the use of traditional models for this purpose is not possible. Therefore, today the use of other methods such as machine... 

Market share of some private insurance companies in Iran has demonstrated upward and then downward trends over the years . Due to the similarity of conditions among all companies, the internal structure of companies is the main reason for the creation such trends. The operation of insurance companies has a lot of feedback mechanisms and delay relationships. In this research for purpose of modeling a holistic and comprehensive view and understanding the structure of private insurance companies in Iran, feedbacks and delay relations System dynamics approach is used. The developed model structure consists of five interconnected modules, each representing a relatively detached sphere of... 

Iran has the third largest reservoirs of oil and the second largest reservoirs of gas and has the greatest hydrocarbon reservoirs worldwide. Considering the fact that production of oil is highly dependent on gas injection, Iran is facing a great challenge in determining proper strategy for consuming natural gas. Due to the lack of proper strategy form the point of view of economical as well as scientific evaluation in political and social aspects, it has resulted in weakening Iran’s place in international markets and also reduction of oil wells’ productions.In this study, after a review of relevant literature, characteristics of oil and gas projects effective on modeling them were...
