Purpose: Managers are one of the important elements of an organization, for this reason, in order to draw the future of the organization, it is necessary for the planners to specify the conditions of their selection and appointment. Therefore, the current research has been done with the aim of identifying and analyzing the components of selecting future principals.Method: In this research, COMPARATIVE and benchmarking method is used as a prospective approach. This approach is based on the belief that today's advanced organizations/countries can be considered as a model for the future of another organization/countries in their respective subjects. For this, first, the fields of comparison and benchmarking were determined using Brody's four-step comparison method; then the countries of Canada, Finland, Australia, South Africa, and Japan were selected according to the qualitative balance value in the international advanced TEAMS test, human development index, life quality index(health, instruction, and welfare), education quality index, and other scientific-scholarly indexes; finally, by extracting the criteria for the selection and appointment of principals through content analysis and comparison with Iran, the proposed framework for Iran has been presented.Findings: A total of 61 components for the selection of secondary school principals were identified from among the studies conducted in the selected countries in this article. By extracting the commonalities and differences of each of the components among the countries, it was found that the highest index of manager selection and appointment belongs to Japan and the lowest one is related to Finland.Conclusion: There are similarities between the components of selection of principals of secondary schools in Iran and selected countries. In Iran, special attention should be paid to important components such as adherence to religious principles, appropriate personality traits, creativity and innovation, motivation to develop capabilities, professional growth, power of supervision and accountability, social image, leader skills, and purposefulness and foresight.

Automatic topic detection seems unavoidable in social media analysis due to big text data which their users generate. Clustering-based methods are one of the most important and up-to-date categories in topic detection. The goal of this research is to have a wide study on this category. Therefore, this paper aims to study the main components of clustering-based-topic-detection, which are embedding methods, distance metrics, and clustering algorithms. Transfer learning and consequently pretrained language models and word embeddings have been considered in recent years. Regarding the importance of embedding methods, the efficiency of five new embedding methods, from earlier to recent ones, are compared in this paper. To conduct our study, two commonly used distance metrics, in addition to five important clustering algorithms in the field of topic detection, are implemented by the authors. As COVID-19 has turned into a hot trending topic on social networks in recent years, a dataset including one-month tweets collected with COVID-19-related hashtags is used for this study. More than 7500 experiments are performed to determine tunable parameters. Then all combinations of embedding methods, distance metrics and clustering algorithms (50 combinations) are evaluated using Silhouette metric. Results show that T5 strongly outperforms other embedding methods, cosine distance is weakly better than other distance metrics, and DBSCAN is superior to other clustering algorithms.

Competition law is a newcomer to the legal system recently. A sound understanding of competition policy can provide us with sufficient bases to apply a fundamental and normative view of the issues of competition law. The difference in supervision and regulation determines how the market functions and in order to understand this difference one must understand competition policy. Competition policy may be based on governmental support for national production and industry or on a non-interventional and regulatory posture. Moreover, supervision, based on the principle of non-intervention in the market mechanism, is rooted in liberal ideas; however, regulation, whether as a rule or an exception, is based on the assertion that the market has been ineffective in attaining its goals. Therefore, the government will resort to interventions to regulate inefficiencies.  This paper aims to analyze Supervisory Authority in Implementing Competitive Policy by employing the description method. In this article the author tries to first delineate competition policy, its related requirements and imposed deviations to the market. Then, by defining the supervisory entity and clarifying its distinction from the regulatory institutions, the author considers the characteristics of an appropriate supervisory entity conducting a COMPARATIVE study of this issue in Iran and the U.S.A. This form of Competition policy because of its applicable experiences which have been well described by recent scholarship is considered suitable for the native system.

As a part of the human society, children have formed the future generation of every country, and the child's interaction with the surrounding environment requires his physical and mental development. Therefore, it is important to pay attention to the environment that promotes mental and physical development of the child. In order to check the suitable environment for children, the initiative of the child-friendly city has been taken into consideration. The general purpose of this research is to improve the status of two cities from the perspective of a child-friendly city and to identify the appropriate indicators of a child-friendly city and to make a COMPARATIVE comparison in the two metropolises of Tehran and Isfahan. The current research is developmental in terms of the combined method and in terms of the goal, and it is based on library and documentary studies, field surveys and interviews. Yeoman-Whitney test was used to analyze the indicators. The results of the evaluation show that in the comparison of the two cities of Tehran and Isfahan in terms of the examined indicators (social and physical, economic, environmental, urban management and leisure), Tehran city in the variable of safety and protection with an average of 3.09 and Isfahan city in Participation and citizenship variables with an average of 3.22 have a favorable level. Although Tehran is in a better condition compared to Isfahan in other indicators, in general, both cities are far apart in terms of standard indicators, and suggestions have been made in this regard.

A B S T R A C TSatisfaction is considered one of the effective methods for evaluating the success of urban development plans and projects, and it is a tool to measure which type of housing and residential environment meets the needs, expectations, and aspirations of residents. This article aims to compare Amiriyeh and Pay-eToop neighborhoods in Bojnord city in terms of residents' satisfaction with living in these neighborhoods. Using a questionnaire, the data was obtained by a survey from 229 heads of sample households living in Bojnoord city. The residents' satisfaction is analyzed by 26 indicators set as home and neighborhood indices. The data is entered into SPSS software to run the One Sample T-Test and calculate statistical parameters. Also, the data is entered in Arc GIS in accordance with the UTM coordinates of the responder's locations to provide a GIS point layer to use zoning maps to be drawn. Residential satisfaction is lower than average and slightly higher in Pay-eToop than in Amiriyeh. Also, the average score of the indicators that are set as home indices is lower than those for neighborhood indices. The zoning maps indicate that most parts of the neighborhoods show an average level of satisfaction with housing, and the maps of different indicators are not much different from each other. The role of physical indicators in low satisfaction is much more significant than social indicators. To improve satisfaction, paying attention to the neighborhood regeneration and improving the housing quality is necessaryExtended AbstractIntroductionSatisfactory housing is one of the most valuable aspects of life and one of the main elements of people's living standards. The higher the level of satisfaction with a place, the more people will feel a sense of belonging to that place and feel more relaxed about being there. The feeling of satisfaction from a place can cause the positive effects of the place in the process of relationships in which the environment is being formed and carried out. On the one hand, satisfaction measurement is considered one of the effective methods of evaluating the success of urban programs and plans. On the other hand, it is a tool to measure which type of housing and residential environment currently meets its residents' needs, expectations, and aspirations. MethodologyThe residents' satisfaction is analyzed by 26 indicators set as home and neighborhood indices. A questionnaire gathers the data. Household heads in the studied neighborhoods (Amirieh and Pay-e Toop) are randomly selected as 229 sample people. The sample people evaluate the items in the questionnaire in a 5-range of the Likert scale from very high to very low. The qualified range was then changed to quantified scores from 5 to 1. Afterward, they were entered into SPSS software to run the One Sample T-Test and calculate other statistical parameters. The address of each respondent is included in the questionnaires, and based on the address, the UTM coordinates of the respondent are determined using Google Earth. Then, the information from the questionnaires is entered into the GIS according to the coordinates to provide a GIS point layer for drawing zoning maps. Results and discussionThe score of 2.75, which is the average figure of the evaluation scores for all the indicators of both neighborhoods, indicates that residential satisfaction is lower than the assumed average score (3). The average scores are 2.90 and 2.57 for Pay-e Toop and Amirieh neighborhoods, respectively, and they indicate that the residential satisfaction in the first is slightly higher than the other. Pay-e Toop is the oldest neighborhood in Bojnoord, which accommodates the traditional complex of shops (Bazar) and essential physical elements of historical eras, such as the city's citadel. In addition to the high proportion of immigrants, it also includes deep-rooted and native families that have strong social relationships. Also, the average score for the neighborhood indices is slightly higher than for the home indices. The average figure for all 26 indicators is lower than the assumed average score (3) and indicates a lower residential satisfaction. Five indicators with the higher satisfaction score are as follows: relationship with neighbors, living in the ancestral neighborhood, the situation of streets and ways, living with relatives, and the quality of wastewater disposal. On the contrary, lower satisfaction scores belong to the indicators of access to shopping centers, healthcare service centers, the size of homes, and access to public transportation, respectively. Despite the fame of the gardens of Bojnord in previous centuries, in recent decades, most of the gardens disappeared, especially in the city's central business district, which corresponds to the two studied neighborhoods; there is a small area of land covered by parks and green spaces. Green spaces are mainly the small green strips on the edge or in the middle of the streets. For Amiriye and Pay-e Toop neighborhoods, the Pearson correlation coefficient between the respondents' education levels and their scores of residential satisfaction are -0.36 and -0.23, respectively. It implies that residential satisfaction has an inverse relationship with education. Also, the correlation coefficient between the residence length in the neighborhood and residential satisfaction scores are +.001 and -0.29, respectively (for Amirieh and Pay-e Toop neighborhoods). It also indicates no relation for the first neighborhood and an inverse relation for the other.The zoning map of all the indicators shows that in more than 90% of the neighborhood area, the level of satisfaction is in the medium range. In Amirieh, the parts with low satisfaction are scattered. It can be said that the northeastern edge of the Amirieh neighborhood and the southwestern edge of the Pay-e Toop neighborhood have lower satisfaction. ConclusionThe role of physical indicators in low satisfaction is much more significant than social indicators. The physical components of the neighborhoods caused a low level of satisfaction. On the contrary, higher satisfaction is revealed from the socio-cultural components. Households prefer the quality of services more than the availability of services. In medium-sized cities such as Bojnoord, neighborhood relations, closeness to relatives, and living in neighborhoods where the ancestors lived are still decisive in creating residential satisfaction. To improve life satisfaction, paying attention to housing quality and the regeneration of both neighborhoods is necessary. Also, improvement, retrofitting, enhancing the quality of the building, and improving the quality of urban services, especially healthcare services, public transportation, and commercial services, should be considered. FundingThere is no funding support. Authors’ ContributionAuthors contributed equally to the conceptualization and writing of the article.

Knowing the approaches of the commentators (the scholars who interpret the Holy Book of Quran) of Quranic researching provides the basis for understanding, analyzing and criticizing their views and opinions, because tafsīr (Arabic: تفسیر, exegesis) texts are influenced by the commentator’s worldview and mental ideas, as well as a reflection of the cultural and social requirements of his era. One of the issues that has recently become a subject in the field of understanding and interpreting the Holy Book of Quran is the effect of gender element in the understanding of religious texts. Therefore, this research, using descriptive-analytical method in a COMPARATIVE context, has investigated the tendency, Fundamentals and exegetical methods of “Āmina Wadud” (Arabic: آمنة ودود) and “ʿĀʾisha Bint al-Shāṭi” (عائشة بِنت الشاطئ) two of the Quran researchers. The obtained results indicate that the interpretative tendency of Āmina Wadud is social, transsexual and justice-oriented. She has used the hermeneutic method and philosophical analysis in explaining the discourses of the Qur'an in this regard. The tendency of the fundamentals and methods in the Quranic understanding of Āmina Wadud in her social commentary leads her to Islamic rulings in the field of women in order to present a new and modern reading of them. But Bint al-Shāṭi’s exegesis tendency is theological literary in line with the Quran’s verbal inimitability (Arabic: الإِعجاز البیانیّ, Romanized: al-Iʾjāz) of the Holy Book of Quran. She is trying to put emphasis and style (the methods used in written language) on the verbal inimitability of the Holy Book of Quran by a linguistic point of view in line with the method of verbal exegesis.

Introduction: Due to increase in the number of elderlies, the importance of improving the quality of their lives has been highlighted, as such, dental professionals need higher knowledge and education on dental and medical complications in addition to controlling them in older generations. This study endeavored to compare the gerodontology course in the curriculum of undergraduate dental students in Iran and other selected countries based on a demographic model. Methods: In this descriptive-COMPARATIVE study, the comparison between gerodontology course in curriculum of Iranian faculties and other selected countries (Japan, India, Spain, Germany, Switzerland, USA, Canada, Australia and South Africa) was made based on Bereday’s COMPARATIVE method in education. This way, first, all subjects regarding gerodontology were collected from the curricula and tabulated, then the subjects were analyzed in four steps like this: description, interpretation, juxtaposition, and comparison. Results: The collected data revealed that some topics of gerodontology are more important. Thus, despite differences in policies, they are included in the majority of the reviewed curricula. For example, we can mention topics related to systemic diseases, pharmacology, prosthetic treatments and, communication with elderly patients. Conclusion: Gerodontology is included in all the reviewed curricula and the importance of its topics has been noted in all countries, however, the details of the topics and teaching methods are different, which can have various reasons.

After the birth of the “cytogenetics” in 1956 and its application in medicine in 1959 as valuable tool for the diagnosis of congenital diseases caused by chromosomal abnormalities, its limitations persuades the investigators to discover and employ “banding” techniques. This method could overcome many pre-existing problems and limitations but was not diagnostic especially when tissue culture was not possible due to tissue necrosis or in microdeletions. Fortunately, Fluorescent In Situ Hybridization (FISH) could prevail over many of the aforementioned limitations but it could not evaluate necrosed tissues since it required a specific probe for each disease. Array COMPARATIVE Genomic Hybridization (aCGH) is a new technique which enables us to study both necrosed and viable tissues. Another advantage of this method is the ability to study the whole genome and assess any decrease or increase in the chromosome material. This technique is currently regarded as the best and most efficient. Since stillbirths and viable or necrosed curettage specimens comprise most of the referred specimens to Kariminejad & Najmabadi Pathology and Genetic Center and evaluation of the specimens with a special focus on chromosomal aberrations are required by clinicians, we have equipped our center with technical equipment and experienced cytogenetic technicians. In the end, two cases whose definite diagnoses were made using FISH and Array CGH are presented.

Human, as the product of the village, is the main determinant of the formation of a place and the future development path. Among the significant concerns regarding the villages of Kuhdasht County is the extensive migration of natives. Therefore, in line with addressing the overarching theme of "the role of place in the process of rural development," the problem of this research is posed as "How is the development place in the daily life of villages in the Kuhdasht region?" Indeed, based on the assumption that "place connects human and village through mutual care pathways," the "village" is introduced as the "development place," providing a space for the daily life of human and village to achieve the "achievements" resulting from confronting unique and continuously complex hardships in the form of space. The research aims to elucidate a comprehensive model of the development place in the daily life of villages by addressing the two questions, "How is the built landscape of the village in the Kuhdasht region?" and "How is the lived landscape of the village in the Kuhdasht region?" To achieve compatibility in the "common perceived reality" of the two research questions, there is a need to compare two parallel semantic domains. This means that "descriptions of the region that are the result of observation (present)" are accounted for through thematic analysis, and "descriptions of the region that are the result of lifeworld experiences (non-present)" are accounted for through the hermeneutic phenomenology strategy, and the findings of these two steps are summarized with equal weight. The research findings revealed three dimensions: "performance," "ideology," and "assets" for the first question. In the second question, three experiences—"common birthplace," "common function," and "common assets"—were o obtained from phenomenological interviews. Finally, by comparing the results of these two stages, a model consisting of four dimensions—"place,"," "assets," "social space," and "unction"—was summarized.
