A B S T R A C T Green city is one of the approaches to sustainable development. “green city” is an environmentally friendly city compatible with the concept of sustainable development and can be used for the welfare and security of its inhabitants. Based on the concept of a “green city,” urban managers try to have the least destructive effect on the ecosystems upon which cities rely. Green city is one of the sustainable development approaches that reduce the environmental footprint of cities. The purpose of this study is to evaluate the situation of Mashhad metropolis in terms of the objective characteristics of the green city. In this study, 14 indicators of electricity consumption per capita, green space per capita, population density, water availability, sewage availability, superior public transportation network, urban mass transportation, traffic reduction, annual production waste per capita, carbon monoxide, concentration nitrogen dioxide, sulfur dioxide concentration, particulate matter concentration, and air quality were exerted. To determine the importance of research indicators, the Shannon entropy method, and the status of Mashhad city areas in terms of green city indicators, the VIKOR multi-criteria decision-making method has been applied. The results showed that most areas of Mashhad are average and below average in terms of green city characteristics, and only District 9 is in very good condition (0.636). Also, based on the results of this part of the research, District 5, with the value of VIKOR index of 0.969, is in the last rank in terms of objective characteristics of the green city Extended Abstract Introduction Green city is one of the approaches to sustainable development. A “Green city” is an environmentally friendly city compatible with the concept of sustainable development and can be used for the welfare and security of its inhabitants. Based on the concept of a “green city,” urban managers try to have the least destructive effect on the ecosystems upon which cities rely. Green cities constantly try to manage their environmental effects by reducing waste, increasing recycling, reducing air pollution, increasing population density, developing open urban spaces, and encouraging the development of sustainable local businesses. Green cities were first used to evaluate 30 European cities by the Economist Intelligence Unit (EIU) in 2009 with the financial support of Siemens and the aim of reducing the environmental effects of human activities in cities. In that study, eight indices of carbon dioxide, energy, construction, transportation, water, recycling and land use, air quality, and environmental governance were used. Later, the Economist Intelligence Unit, with the financial support of Siemens, evaluated the status of the green city index in 17 Latin American cities, 15 African cities, 22 major Asian cities, and 27 cities in United States, Canada, Australia, and New Zealand. In recent years, even some Western Islamic scholars have, in various publications, shown that Islam is an ecological religion. In Iran, the issue of protecting the environment has not received much attention regardless of its rich cultural and religious background and its confirmation in Article 50 of the Constitution of the Islamic Republic of Iran. Mashhad is the second metropolis of Iran, located in North-East of Iran, and is one of the counties of Khorasan Razavi Province. According to the 2016 Iranian Population and Housing Census, its population was 3057679 people (The Vice-Presidency of Planning and Development of Mashhad Municipality). In Mashhad, due to several reasons including the presence of Imam Reza Shrine (PBUH) and arrival of millions of pilgrims per year, population growth, increased garbage production (production of 896534 tons of garbage in 2016 (The Vice-Presidency of Planning and Development of Mashhad Municipality), air pollution (increased number of unhealthy days from 46 days per year in 2015 to 88 days in 2016 for sensitive groups and 4 days of unhealthy air for all groups in 2016 (Center for Monitoring Environmental Pollutants of Mashhad Municipality) the 2025 vision of the city has paid attention to the environment in the form of five general objectives; however, just like the national level, no specific pattern for environmentally-compatible urban development, such as green city, is determined. Analysis of the green city index in Mashhad metropolis can considerably contribute to urban managers and planners in addition to providing a pattern for evaluating the present situation in other cities of Iran and improving the quality of life regardless of the current status of the urban environment in Iranian cities; we can preserve these environments as parts of the natural environment for future generations.   Methodology In terms of its goal, the present study is an applied one; in the study, drawing upon other studies and library sources and considering the conditions of Iran and the metropolis of Mashhad in terms of green city, 14 quantitative indices were exerted. To this end, the required data for the quantitative indices was gathered by library research from the relevant institutions. Next, the weights of quantitative indices were determined using Shannon's entropy. Then, using the VIKOR method of multi-criteria decision-making, the status of various districts of the metropolis of Mashhad in terms of quantitative indices of green city was determined. Finally, the map of the spatial distribution of quantitative indices was drawn using the ARC GIS software package.   Results and discussion In this study, to analyze the status of the metropolis of Mashhad in terms of green city features, 14 quantitative indices were used. Considering the value of the VIKOR index ranges from 0 to 1, various districts of Mashhad can be classified into five categories; very satisfactory, satisfactory, average, unsatisfactory, and very unsatisfactory in terms of quantitative indices of green city. The results of the current situation of Mashhad showed that in terms of objective indicators of the green city, District 9 of Mashhad metropolis with a value of VIKOR index of 0.056 is in first place, and the seventh region with a value of VIKOR index of 0.433 is in second place. Also, based on the results of this part of the research, District 5, with the value of VIKOR index of 0.969, is in the last rank in terms of objective characteristics of the green city.   Conclusion Similarly, the results of studies by Afshar (2011) and Shabani et al. (2017) on Tehran metropolis are indicative of the unsatisfactory situation of Tehran (the biggest metropolis of Iran) in terms of green city features. Comparing the results of the studies by Afshar (2011) and Shabani et al. (2017) with the present study on Mashhad (the second biggest metropolis of Iran) reveals the necessity for a comprehensive plan toward achieving green cities. It should be mentioned that, due to the specific conditions of Mashhad metropolis and availability or unavailability of the required data, the indices used in the present study are somewhat different from the ones used by Afshar (2011) and Shabani et al. (2017).   Funding There is no funding support.   Authors’ Contribution All of the authors approved the content of the manuscript and agreed on all aspects of the work.     Conflict of Interest Authors declared no conflict of interest.   Acknowledgments We are grateful to all the scientific

چکیده: 

شاخص اهداف توسعه پایدار در سال های اخیر توجه بسیاری از محققان و سیاست گذاران را به خود جلب کرده است. شاخص توسعه انسانی نیز که بر اساس چند شاخص مهم و کلیدی محاسبه می شود اگرچه یک روش قدیمی تر برای مقایسه کشورها در بعد سلامت و آموزش به حساب می آید اما همچنان در بین محققان و سیاست گذاران یک شاخص موردقبول است. هدف از این مطالعه بررسی وضعیت ایران در شاخص توسعه انسانی و شاخص اهداف توسعه پایدار و نیز بررسی همبستگی این دو شاخص بر اساس اطلاعات تمام کشورها است. در این تحقیق از روش همبستگی پیرسون و رگرسیون خطی در نرم افزار SPSS به منظور بررسی ارتباط بین دو شاخص استفاده شده است. نتایج نشان می دهد که ارتباط معنی دار و قوی بین این دو شاخص برقرار است. در بررسی همبستگی بین اهداف 17 گانه اهداف توسعه پایدار با شاخص توسعه انسانی مشخص شد که اهداف 15 و 17 ارتباط معنی داری با شاخص توسعه انسانی ندارند. درحالی که ارتباط دیگر اهداف با شاخص توسعه انسانی معنی دار بود. به طورکلی می توان نتیجه گیری کرد بین شاخص توسعه انسانی و شاخص اهداف توسعه پایدار ارتباط معنی دار قوی وجود دارد. درحالی که آرمان 17 با هیچ کدام از زیر شاخص ها دیگر و شاخص توسعه انسانی ارتباط ندارد. یکی از نقطه ضعف های اهداف توسعه پایدار مدنظر قرار دادن آرمان های بلند پروازانه است و این موضوع بسیج مردم و حکمرانان را برای رسیدن به تمام این اهداف ایده آل سخت خواهد کرد.

Since the evaluation of the diversity indicators in consumption of medicinal species by the beneficiary’s households and its driving factors is of utmost importance in marketing, multi-purpose planning of rangelands and sustainable development, a questionary-based study was carried out to determine the diversity indices of medicinal species consumption in settled nomadic communities living under different management and livelihood situations in the rangelands of Dyvaroeieh in Bardsir township, Kerman province, Iran. To this end, the medicinal species consumed by each household (as a study unit) in addition to the diversity indicators of consumption (i.e., dominance coefficient and Shannon-Weiner index) were evaluated under two management sites comprising Rangeland Management Plan (RMP) (i.e.,Dvyaroeieh 1) and the nearest adjacent rangeland without RMP (i.e., Dyvaroeieh 2, as control treatment ) and three livelihood levels (i.e., very poor (<50 million Rials monthly income), poor (50-100 million Rials monthly income) and moderate (100-150 million Rials monthly income)) under factorial test in SPSS software environment. The study's results revealed that both of management and livelihood factors can be applied by manager to increase diversity indices in medicinal plants consumed by beneficiaries. More specifically, management through RMP was more powerful and effective tool in this way. Therefore, it could conceivably be argued that RMP can be considered as a driving factor in increasing the diversity of medicinal plant consumption and also be a suitable platform to meet the needs and demands of rangelands’ beneficiaries in this field.

چکیده: 

ABSTRACT Over the past 50 years since the first research in the field of urban development implementation plans, there has been a noticeable absence of a comprehensive literature review on this topic in the global arena. This article provides a textual analysis related to the subject of urban development implementation plans, to identify important and recurring themes alongside analyzing the relationships between authors, journals, and countries in this field. Along with the bibliographic analysis, documents related to the field of urban development implementation plans were reviewed to identify influential indicators in their implementation. To this end, 456 scientific articles were extracted from the Scopus scientific database as of October 28th, 2022, and analyzed using scientometric software. These analyses include examining author keywords, country co-authorships, journal bibliographic coupling, and author co-citations. In this study, 74 final indicators were identified as the most recurrent indicators in this field. The bibliographic analysis also produced several noteworthy results. The United States is the most active country in this field, with a link strength of 40 and 176 articles. Berke, P. is the most influential author in this field, with a link strength of 1623 and 99 citations. Among the journals examined, "Land Use Policy" has the highest bibliographic coupling strength of 84, and the "Journal of the American Planning Association" has the highest number of documents related to this field, with 22 documents; finally, among the identified. Extended Abstract Introduction The implementation of urban development projects has been a neglected topic in public policy research, despite its critical importance in ensuring the success of such projects. While there have been numerous studies on the factors that contribute to the success or failure of policy implementation, there has been a lack of systematic reviews on the subject of implementation as a whole. This study aims to address this gap in knowledge by providing a comprehensive overview of the implementation process of urban development projects. This study aims to address this gap in knowledge by providing a comprehensive overview of the implementation process of urban development projects. The study begins by collecting and categorizing existing research in the field, focusing on three main questions: -What are the key indicators for successful implementation? -What are urban journals and articles' current trends and performance? -How do countries and researchers collaborate in this area? The study also examines the relationships between authors, publishers, and different types of documents through bibliographic analysis. Ultimately, this study highlights the need for further research and a more structured approach to understanding the implementation process of urban development projects.   Methodology This study examined the literature related to implementation and evaluation plans in urban and land use planning. The authors used the Scopus database to extract and collect data, focusing on combining the keywords "implementation-plan" and "evaluation-plan" in the keywords, abstracts, and titles. Initially, 621 studies were extracted, but 456 articles were selected as the final database after filtering out non-article documents. The authors observed a general upward trend for studies from 1968 to 2022, with a significant increase in the slope of the trend from 2007. However, a slight decrease in studies was observed in 2021 and 2022, possibly due to the global pandemic and the emergence of new related topics. The authors used a four-stage process to analyze the bibliographic subject of the study, including simultaneous occurrence analysis, co-authorship analysis, bibliographic coupling analysis, co-citation analysis, content analysis, and thematic analysis. The authors identified the selected articles' research objectives, methodologies, findings, and main themes and sub-themes. Overall, this study provides a comprehensive analysis of the literature on implementation and evaluation plans in urban and land use planning.   Results and discussion This research aims to comprehensively analyze the implementation and execution of urban development plans using bibliometrics and systematic analysis. The study considers evaluation as a crucial part of the implementation process and seeks to answer three fundamental questions. Firstly, it identifies effective indicators of implementation and execution globally. Secondly, it examines the trends and performances of new articles and urban journals. Thirdly, it investigates the pattern of cooperation among countries and researchers. The study identifies 74 general indicators that significantly impact the implementation process of urban plans. The results show that "performance evaluation," "effectiveness," "land use," "zonation," "participation," "program quality," and "implementation program" are critical indicators in this area. The study also highlights the importance of evaluation in the discussion of program implementation and its separability from the implementation process. Using the scientometric software VOSviewer, the study analyzed 68 keywords related to the bibliographic topic. "Program evaluation" obtained the first place, followed by "Program implementation" and "Program quality." The co-authorship analysis based on author items revealed that Berke, P. has the highest number of citations and link strength. Additionally, the study found that 72 countries have research in this field, with 22 countries having at least 5 citations that were clustered into 5 clusters by the software. The "land use policy" journal had the highest link strength, and the "Journal of the American planning association" had the highest number of documents related to this field. In conclusion, the study provides valuable insights for policymakers and researchers interested in urban development planning. It comprehensively examines the implementation and execution of urban development plans, identifies effective indicators, and investigates the pattern of cooperation among countries and researchers. The study highlights the importance of evaluation in the implementation process and its separability from the implementation process.   Conclusion The main goal of this research was to fill the gap in research on the implementation and execution of urban development projects in the field, as no systematic review of the topic has been conducted from a global perspective since the first research in this field about half a century ago. Only in some studies, such as those by Talen (1996), Oliveira & Pinho (2010), Rudolf & Grădinaru (2017), has the evaluation of implementation been systematically reviewed, or the systematic review of experiences in a specific urban area, such as the review of various experiences in the Beijing urban area (Chu, 2020). In this research, with the comprehensive approach that the evaluation of implementation is an integral part of the overall process of implementing and executing urban development projects, this process has been examined from the perspective of bibliometrics and systematic analysis of this field. The main difference of this research, which makes it completely new, is firstly having a comprehensive approach to the implementation field, where program evaluation is only an important part of its structure, and secondly, using the scientometric software VOSviewer for the first time in this field. In essence, the conclusive outcomes of this investigation were entirely novel and exhibited some partial congruences with antecedent studies in the domain of appraising and discerning indicators. Significantly, this research has conferred a systematic appraisal of the literature concerning the urban implementation and execution of projects, which is an unprecedented contribution. It should be acknowledged that this is an initial survey of data intended to offer a comprehensive outlook on this scholarly field, and thus it is subject to certain limitations, such as its confinement to the Scopus database. As such, it is recommended that future research endeavors encompass an analysis of additional databases and undertake comparative evaluations of the results.

چکیده: 

The situation of women in post-Revolutionary Iran has been under scrutiny by domestic as well as foreign investigators. The existing situation is described by some as "improper" due to the prevalence of a patriarchal society. Another perspective attempts at highlighting the scientific status achieved by the Iranian women in recent years. This article, based on the current perspectives, probes the Iranian women's situation taking into account gender development indices and compares the indices with those of other nations. The article utilizes the library and secondary data analysis methods. Based upon empowerment theory, the present study investigates factors constituting the general context, those contributing to changing women's situation, as well as factors that act to alter the ranking of the gender development indices. Such factors include an increase in the age of marriage, the decrease of fertility, popularization of secondary schooling, and a rise in number of women who enter the universities, all of which help to promote the conditions for women's egalitarianism. Nonetheless, in the areas of employment and management, women's shares remain lower than those of men. Yet, the prevailing circumstances are indicative of an improvement, as women strive for egalitarianism and equal opportunities.

چکیده: 

تقریبا در تمامی مطالعات انجام شده در حوزه مزیت نسبی مناطق، شاخص های عمومی مزیت نسبی مانند اشتغال، ارزش افزوده و سودآوری، مدنظر قرارگرفته است؛ در حالی که مطالعه مزیت نسبی مناطق، بدون در نظر گرفتن معیارهای توسعه پایدار، که عدم آلایندگی از عمده ترین آن محسوب می شود، مطالعه ای ناقص است. بر این اساس، مطالعه حاضر می کوشد با در نظر گرفتن توامان معیارهای عمومی مزیت نسبی مناطق و نیز، معیار عدم آلایندگی به عنوان مبنایی اساسی برای توسعه پایدار، جایگاه و رتبه مناطق کشور را از حیث مزیت نسبی صنایع تولیدی مورد بررسی قرار دهد. برای این منظور، ابتدا صنایع تولیدی مناطق مختلف بر اساس شاخص های عمومی مزیت نسبی رتبه بندی شده و در مرحله بعد، جایگاه آن ها با توجه به تلفیقی از شاخص های عمومی مزیت نسبی و شاخص های آلودگی هوا ناشی از احتراق سوخت های فسیلی در بخش صنعت با استفاده از روش تاپسیس مورد توجه قرار گرفته است. نتایج این مطالعه نشان می دهد مزیت نسبی مناطق در صنایع تولیدی با و بدون در نظر گرفتن شاخص های توسعه پایدار از یکدیگر کاملا متمایز است و از این رو و نیز از حیث سیاست گذاری، مزیت های نسبی مناطق بدون در نظر گرفتن معیارهای پایداری راهنمای مناسبی برای سرمایه گذاری های صنعتی نخواهد بود.
