Objective: The purpose of this research was to study the Search Engine’s responses to authority data properties embedded into schema.org-based metadata on the Microdata syntax.Methods: The experimental method was used in this research. The research population comprised 400 records of authority metadata based on the Microdata method from the digital library of Allameh Tabataba'i University. The examination group consisted of 200 metadata records, 100 records with authority data extensions embedded into schema.org-based metadata in the Microdata syntax and 100 other similar records in the JSON-LD syntax (50 samples of name authority, and 50 other subject authority) And the control group consisted of 200 Records, including 100 Records related to the description of the book in the Microdata syntax and 100 other similar records in the JSON-LD syntax. The records have been published on the independent website at www.Aghadeh.ir and have been introduced to the Google, Bing, Yahoo, and Yandex search engines as designers of the schema.org standard. Then, through searching the search engines, using the data gathering tool, the checklist provided by the researchers, the indexing and retrieval of the metadata records of the control groups and experimental groups were evaluated in the search results of the selected search engines.Results: The results of this study showed that search engines were able to index and retrieve all of the metadata records and values of added extensions associated with authority data. Such a possibility had the same status for the name authority records and the subject authority data.Conclusions: By retrieving each of the variant properties’ values of examination group’s records, in addition to the authorized values of the name and subject terms, a suitable platform for the comprehensiveness of the retrieve process, and the authority control in the Web search tools will be improved.

The aim of this study is to estimate the known statistical characteristics of nominal price stickiness in the Iranian economy during the years 1390 to 1399 and at different commodity levels of Microdata of consumer price index (including product category, Coicop commodity group, and the whole economy) and thus the stickiness between categories and product groups are also compared. For this purpose, 421 categories have been selected as a sample from the database of the Consumer Price Index Statistics Plan of the Statistics Center of Iran. This sample is about 93% of the number of consumer basket items in the base year 95 and 67% of consumer expenditures in the base year 90 covers. In this study, the nominal price stickiness index is estimated via the duration and frequency approaches. According to the results, this index is estimated at 29% based on frequency approaches in the whole economy and about 2. 99 months based on the Duration approaches, which is less than in developed countries. Also, the comparison of indicators at the level of items and Coicop groups shows the existence of heterogeneity in the stickiness of nominal prices. The group of food and beverages and group of housing, water, electricity, gas, and other fuels have the lowest, and the group of communication and education have the highest price stickiness.

Space syntax is an influential theory which has been successfully applied to various disciplines such as archeaology and architecture to analyze spatial relationships. It has been defined as a method for representation and quantification of spatial patterns. Instrumental in this method is the definition of space as a two- dimensional convex structure. The method examines circulation in or through any space. The spaces that connect more spaces are thus defined as more integrated, while those with little circulation are considered to be segregated. Using the same method the central courtyard in a Persian house, for example, is highly integrated, while the talar and orosi rooms are segregated, although these are the most important summer and winter residential spaces, respectively. There are other spatial characteristics that are not considered in the application of the method: size, shape, function, atc. The paper tries to introduce and analyze the method and highlight its advantages and disadvantages.

One of the issues that statistical organizations face in disseminating micro data is confidentiality, which has made the data not easily available to the public. One way to solve this problem is Synthetic simulation. In this article we proposed a simulated method, which is called synthetic, generates data with high similarity to the original population while maintaining confidentiality. Thus, estimated parameters are more accurate. The labor force survey (LFS) is one of the important surveys of statistical center of Iran, which provides valuable information about Iran’ s LFS situation, specially unemployment rate. In this article, an attempt is made to investigate the application of the synthetic method for simulation target population, using results of the Iran’ s LFS, summer 2018, for whole 31 country provinces. Moreover, due to compare the accuracy of Horowitz-Thompson estimates from the simulated population and real population, we have used the asymptotic relative efficiency estimate, which shows that estimation from the synthetic population is more efficient than the estimation obtained from sample of original population. This paper also shows that the proposed method can be used to estimate the parameters of small areas and where the sample size is not sufficient.

Sensitivity in cultural, political, economical and social Inequality led to effort in measuring precision. So, different types of inequality indices are developed and the quality improvement is considered. Due to ever increasing Computer memory capacity and data processing speed, Electronic Cards and transactions, evolution of information and Microdata phenomenon is emerging. Thus, the main purpose of this study has been to apply Microdata Distribution Expenditure (Income), in order to estimate with more precision the Economic Inequality in Iran and to use the opportunity for testing consistency among the different inequality indices in the distribution of income. The results indicate that the average urbanGini coefficient has significantly increased during (2000-2001) in compare with (1996-1999), while there has been no difference in the rural areas. According to the results, one may cautiously state that the beginning of the third 5-years developing plan has started with increase in economic inequality. The down-up inequality trend in urban areas and the up-down trend of inequality in rural areas during 1996 to 1999 indicate the lack of any definite and effective policy concerning the income distribution in Iran.  

Scholars have done various discussion on syntax and its origin. What can be infered from their argument is that, Arabic grammatical rules have lost their influences. Therefore, the leading proponents of syntactic school have tried to avoid this problem by writing grammatical rules for Arabic. Such attempts have been conducted by schools of Kufa, Basrah and Baghdad. It goes without saying that each of these schools possess its own rules and regulations. To teach the syntax remained from the past in accordance with the Basrah end Kufa school is considered to be neither appropriate nor right. In devising new syntax to fulfil our needs, descriptive approach is viewed as the best Choice. In recent descriptive studies, syntax: is devised based on both spoken and writen language. Such a descriptive appro<"lch includes both the over all shape and the change in the final vowels of Arabic words. Dialects are unacceptable issues because they are not based on descriptive syntax and they are far from it.

The equality implications of tariff design for household gas and electricity, two essential substitutes, present a significant concern for policymakers. In this study, we examine this issue using a sample of household income quartiles across various social groups, exploring the diverse effects of changes in electricity and gas prices. The findings reveal that an increase in gas prices exerts a more pronounced impact on low-income groups compared to an equivalent increase in electricity prices. Our partial analysis indicates that gas exhibits less elasticity, likely attributed to the absence of a suitable substitute in the event of a price increase for this commodity. This observation underscores the lack of energy diversity that is rooted in the critical role of gas appliances in cooking and heating. This phenomenon poses a potential threat to the energy security of Iranian households.

Background: Dramatic changes in the demographic behaviors of Iranian women have led to declining fertility after the mid1980s. Childlessness is an important and growing issue and has increasingly become the focus of the problem by Iranian population policymakers. Methods: The present study was conducted using the quantitative secondary data analysis method. Using the census Microdata of population and housing in 2016, the researchers attempted to investigate the level and predictors of childlessness among married women aged 40–, 49. The data of 85799 married women aged 40–, 49 was analyzed. Results: About 4% of the sample were childless. Logistic regression analysis indicated that the probability of childlessness for married women with university degrees, immigrant women, and employed women is higher than their counterparts. Furthermore, the findings suggested that women who live in apartments and those who live in private houses are less likely childless than their counterparts. Bigger houses lower the probability of being childless. Conclusion: Government planning and policymaking to reducethe proportion of childlessness should improve household circumstances, especially their housing.
