چکیده: 

در تحقیق حاضر به بررسی ساختار قدرت در خانواده و تاثیر آن بر میزان مشارکت اجتماعی در بین نمونه ای از افراد بالای 25 ساله در شیراز و به روش پیمایشی پرداخته شده است. چارچوب نظری مورد استفاده در این تحقیق، یک چارچوب ترکیبی بوده است و پایه اصلی تئوریکی نیز بر مبنای نظریه کنش اجتماعی پارسونز بوده است. مشارکت اجتماعی به عنوان یک کنش اجتماعی در نظر گرفته شده است. با توجه به این که نظام شخصیت در نظریه پارسونز محل بررسی نظری کنش متاثر از نظام اجتماعی و فرهنگی می باشد، تمرکز نظری بر نظام شخصیت می باشد. شخصیت افراد در فرآیند اجتماعی شدن در خانواده شکل اصلی خودرا پیدا می کند. بر مبنای نظریه فیشباین و آیزن، کنش افراد متاثر از نگرش آنها به یک موضوع و همچنین هنجارهای ذهنی که از طرف گروه های مرجع القا می شود، می باشد. لذا در این پژوهش ساختار قدرت خانواده به عنوان گروه مرجع، به عنوان عاملی در نظرگ رفته شده است که نگرش افراد را به موضوع مشارکت و همچنین حضور آنها در فعالیت های گروهی را تحت تاثیر قرار می دهد. نتایج تحقیق نشان می دهد هرم قدرت در خانواده های شیرازی، در کل عمودی است. در حالی که در تصمیمات با برد پایین، تمایل بیشتر به سوی مشاعیت می باشد، امادر تصمیمات بابرد متوسط و گسترده، میزان مشاعیت کمتر است. میزان مشارکت اجتماعی در بین خانواده های ساکن شیراز در کل پایین است. بر طبق نتایج حاصل از آزمون فرضیه، بین ساختارهای قدرت در خانواده از نظر میزان مشارکت اجتماعی تفاوت چندانی وجود ندارد. نتایج حاصل از تحلیل رگرسیون گام به گام، حاکی است دو متغیر نگرش به مشارکت اجتماعی و جنسیت در معادله باقی مانده اند و در کل 7.2 درصد از تغییرات متغیر وابسته را تبیین کرده اند. بر اساس نتایج حاصل از تحلیل مسیر علی، با توجه به تمامی تاثیرات مستقیم و غیرمستقیم متغیرهای مستقل بر میزان مشارکت اجتماعی، متغیر نگرش به  مشارکت، بیشترین تاثیر افزایشی و متغیر جنسیت نیز بیشترین تاثیر کاهشی را بر میزان مشارکت اجتماعی داشته است. متغیر ساختار قدرت در خانواده بر میزان مشارکت اجتماعی، تاثیر افزایشی دارد. یعنی هر چه تصمیم گیری در خانواده بیشتر مشارکتی و افقی باشد، میزان مشارکت اجتماعی فرد نیز بیشتر است.

چکیده: 

در این مقاله رابطه بین ساخت قدرت در خانواده و مشارکت اجتماعی افراد در بزرگسالی در میان نمونه ای391 نفری از افراد بالای 25 سال ساکن تهران بر اساس روش پیمایش مورد تحلیل قرار گرفته است. هدف اصلی این مطالعه بررسی این مساله‏ است که چگونه افراد از طریق فرایند جامعه پذیری تبدیل به افراد بزرگسالی می شوند که مشارکت اجتماعی آنها می تواند به استمرار، اصلاح، تقویت و یا تغییر شکل جامعه مدنی کمک کند. رویکرد نظری پژوهش رویکرد تکوینی است که بر اساس آن شکل گیری مشارکت اجتماعی و تقویت جامعه مدنی متاثر از زمینه های تکوینی افراد است، جامعه مدنی توسط افرادی که در حال شکل دادن به هویت های مدنی خود هستند، ساخته می شود. متغیر ساخت قدرت در خانواده در قالب ساخت قدرت یک جانبه پدر محور، یک جانبه مادر محور، متقارن نسبی و متقارن همه جانبه که نشانگر طیفی است که در یک سوی آن استبداد و در طرف دیگر آن دموکراسی قرار دارد اندازه گیری شد. متغیر وابسته در قالب یک طبقه بندی سه گانه از مشارکت یعنی مشارکت با برد محدود، مشارکت با برد متوسط و مشارکت با برد گسترده مورد سنجش قرار گرفت. استنباط آماری از داده ها نشان می دهد خانواده نقش مهمی در ایجاد روحیه مشارکت جویی در افراد دارد. هر اندازه ساخت قدرت در خانواده برابرتر و مبتنی بر تصمیم گیریهای مشارکتی باشد فرزندان در بزرگسالی به سمت مشارکت های با برد گسترده و با شعاع عمل بیشتر مانند عضویت در احزاب، تشکل ها و ... گرایش پیدا می کنند. بنابراین به جهت اهمیت جایگاه خانواده در ایران ایجاد زمینه های رشد و تقویت خانواده دمکراتیک جهت ایجاد شهروندانی دمکرات و مشارکت جو بسیار ضروری و حایز اهمیت است. به نظر می رسد برنامه‏ریزی منسجم در این زمینه نتایج ماندگارتر و نهادینه تری نسبت به اتخاذ رویکردهای بالا به پایین (دمکراسی از بالا) در جامعه ایران داشته باشد.

Water Water deficit especially after heading is one of the most effective factors of wheat yield loss in Iran AND across the world AND identifying the physiological traits related to plant resilience is of great importance in screening for tolerant varieties. The objective of this study was to evaluate the variation in stem reserves accumulation capacity AND its relationship WITH remobilization in some wheat cultivars. 22 wheat cultivars were cultivated in a split plot design WITH three replications, full irrigation AND 40% of field capacity being main plots. The amount of accumulation AND remobilization was estimated by measuring internodes weight AND stem soluble carbohydrates content (WSC). Significant genotypic variation among cultivars was observed under both normal AND drought conditions. Maximum accumulation was found in lower internodes followed by peduncle AND penultimate using dry weight measurement method. In WSC measurement method, however, maximum accumulation was observed in penultimate followed by lower internodes AND peduncle. Cultivars ranking based on accumulation was also different in two methods. Drought stress caused decline in internodes weight, WSC AND yield AND remobilization efficiency. The specific stem weight had the highest correlation WITH remobilization. Significant correlation was found between grain yield AND remobilization, specific stem weight AND WSC.

چکیده: 

ABSTRACT WITH the expansion of inefficient tissues, "Urban regeneration" has been objectified as a solution for developing cities in different physical, social AND economic dimensions. Despite the development of the guidelines for urban regeneration projects, these projects in Iran still have challenges in the stage of realization AND implementation. This article aims to identify the "challenges AND causes of non-realization of urban regeneration projects in Iran" AND analyse the research conducted in this field WITH a qualitative approach. For this purpose, a meta-analysis of 23 articles in the field of problems of urban regeneration projects in Iran was carried out. The challenges raised in the AtlasTI software were extracted WITH the help of open AND axial coding. In the following, 100 codes were determined in the form of 10 groups or general categories. In the end, the obstacles to the realization of urban regeneration projects in Iran were given. According to the obtained results, the weak presence of non-governmental organizations, the problems of preparing plans, institutional AND management problems, AND the weakness of PARTICIPATION are the four most important AND frequent challenges in the research related to the realization of urban regeneration projects in Iran Extended Abstract Introduction The trend of urban population growth AND the expansion of inefficient urban fabrics along WITH the increasing immigrant population to the cities makes the planners think of filling the existing urban fabrics WITH excessive density AND lAND use change, instead of the city horizontal development WITH regard to the urban sustainable development prism. Poor housing, low per capita services, lack of necessary infrastructure, low quality of life, economic stagnation AND functional inefficiency, unorganized physical-spatial structure, high vulnerability to earthquakes, loss of social status, AND various social problems exemplify the typical challenges of such deteriorated areas. Deterioration of the urban fabric has prompted the emergence of various urban development policies among which regeneration as an overarching approach characterized by its economic, social, environmental, physical, ecological dimensions AND components including quality of life, justice, revitalization AND PARTICIPATION. This concept, as an urban development policy, has been defined AND applied in the vulnerable AND deteriorated areas of cities in recent years. Started from physical redevelopment in the Second World War AND passing through policies concentrated on social AND economic welfare, urban regeneration policies moved towards the PARTICIPATION of local residents AND the creation of sustainable places in recent decades. However, taking into consideration the manifestation challenges of urban development plans, in the existing literature, urban regeneration challenges have been less comprehensively investigated. This paper aims to identify the "challenges AND causes of lack of urban regeneration plans manifestation in Iran" based on the review AND analysis of the research conducted in this field WITH a qualitative approach in response to this question: "What are the challenges AND obstacles to the manifestation of urban regeneration projects in Iran?”   Methodology This research aims to identify "challenges AND obstacles to the manifestation of urban regeneration projects in Iran" through a meta-analysis of the research conducted in this field. Conducting a systematic search in Magiran, comprehensive humanities portal, AND Google Scholar databases using the Boolean logic search used the keyword (challenges) AND key phrases (‘manifestation of plans’ AND ‘urban regeneration in Iran’) resulted in more than 70 Persian papers, 2 English papers, AND 2 English theses. The reviewed studies included research AND review papers, case study research, AND the special issue of urban regeneration policy of Haft Shahr Journal. The geographical scope of the investigated studies covers the historical contexts of Iran, AND metropolises such as Tehran, Tabriz, Shiraz, AND Isfahan. Reviewing the abstracts, 23 studies were selected among which the research focusing on the different types of regeneration, AND evaluation of urban regeneration indicators were excluded from the research process. To conduct meta-analysis after a comprehensive review of each study, open AND focused coding of challenges was done through Atlas.ti software (version 8), AND the obstacles to the manifestation of the plans were extracted. Coding process continued until the saturation was reached. Finally, the 115 codes obtained was reduced to 100 through integrating similar codes. Then, all the codes were categorized into 10 categories, AND a comprehensive model of "challenges of manifestation of urban regeneration projects in Iran" was presented.   Results AND discussion Based on the conducted review, the recognized problems WITH emphasis on the different aspects of urban regeneration projects are: 1) Weak presence of non-governmental organizations (18 codes); 2) Problems of preparing plans (17 codes); 3) Institutional AND managerial problems (14 codes); 4) Weakness of PARTICIPATION (13 codes); 5) Duration AND financial problems of urban regeneration plans (10 codes); 6) Problems of urban regeneration plans process (8 codes); 7) loss of identity of fabrics in the preparation of the plan (6 codes); 8) Lack of context-oriented approach (7 codes); 9) inefficient evaluation of plans (4 codes); 10) lack of social AND specialized training for citizens AND officials (3 codes). The lack of endogenous theory AND insufficient knowledge of the environment AND residents obstacle the manifestation of urban regeneration plans. Despite pretending the use of non-governmental organizations, the relevant law weaknesses, AND the lack of belief in the effectiveness of it has led to disregard of the PARTICIPATION of non-governmental organizations in practice in the process of preparing AND implementing development plans resulting in an inadequate context for manifestation of urban regeneration plans. In addition, the government supervision on NGO’s in the way of achieving independence has also caused limitations for their interplay. In terms of the issues in the preparation of plans, more emphasis on the physical AND economic dimensions AND the purely physical view, AND the lack of attention to the social AND cultural consequences, along WITH the loss of the community identity, are the factors of the failure of the plans to achieve the expected results. The lack of coordination between programs AND multiple decision-makers led to the institutional confrontation instead of interaction. In this regard, the necessity of an integrated AND comprehensive approach to urban regeneration has been acknowledged in the reviewed studies. NGO’s can play an effective role in communicating WITH citizens, educating citizens AND informing them. It is also necessary to have the PARTICIPATION of the private sector AND other organizations involved in the field of urban development in addition to public PARTICIPATION in all steps of preparation, implementation AND occupation of projects AND development plans. In the absence of a context-oriented approach in the preparation AND implementation of urban regeneration plans in Iran WITH blind imitation of western models AND the existence of limited urban infrastructure, following consequences are inevitable: uncertainty in terms of time, cost AND site preparation before the implementation of the plan; lack of definition of urban regeneration plans in the different scales, neighborhood, region AND city; AND the uncertainty of the relationship between these plans AND other urban development plans. As such in the current inadequate conditions driving the process of preparing plans, the possibility of implementing new policies AND plans, is low AND the implemented plans like many other urban development plans in Iran, are inefficient in the absence of the post occupancy evaluation.   Conclusion Based on the results, four priority challenges in the manifestation of urban regeneration plans in Iran include; the weak presence of non-governmental organizations, the problems of preparing plans, institutional AND managerial issues, AND the weakness of PARTICIPATION. "The weak presence of non-governmental organizations" has been mentioned as the first challenge in most reviewed studies (Ahmadifar et al., 2014). Regarding the "PARTICIPATION of citizens" even though in the set of laws AND regulations of sustainable urban regeneration, promotion of citizenship culture, PARTICIPATION, AND cooperation of local institutions are highlighted, the residents are not welcomed in practice. On the other hAND, the lack of people's PARTICIPATION in the preparation AND implementation of plans has made any urban regeneration actions fail or achieve to its partial goals. In this regard, the results of the previous comparative comparisons have shown that the lack of laws AND regulations supporting PARTICIPATION in various fields is of the key factors (Nourian AND Ariana, 2011, Shafie Dastjerdi AND Sadeghi, 2016). The problems of preparing plans, institutional AND managerial issues, ranked as the third AND fourth issues in this study, have been emphasized in previous studies as well (Kalantari Khalil Abad et al., Pakro AND Sattarzadeh, 2014, Izadi et al., 2019). Therefore, prioritizing the challenges raised by experts AND determining operational strategies to solve them are issues that can be addressed in future studies.   Keywords Urban regeneration plans, manifestation, meta-analysis   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.

The Big Five Inventory (BFI) is one of the most WIDEly used personality questionnaires, but very few studies have been conducted on its psychometric properties in Iranian population. This study was carried out WITH the aim of studying the psychometric properties of the BFI questionnaire. For this purpose, 390 university students in Tehran (210 girls AND 180 boys) WITH an age RANGE of 18 to 56 years (M = 27.52; SD = 8.79) were selected using the convenience sampling method AND completed BFI AND NEO-FFI questionnaires. Cronbach's alpha, multitrait-multimethod matrix, AND confirmatory factor analysis were used to estimate the psychometric properties of the questionnaire. The result of the confirmatory factor analysis showed that 15 of the 44 items did not have a strong factor loading (higher than 0.40) on the corresponding factors AND were therefore removed from the questionnaire. The fit indices showed that the Persian version of 29 questions (BFI-29) WITH 5 factors has a good fit WITH the data. The reliability analysis also showed that the RANGE of Cronbach's alpha coefficients of the factors is from 0.70 to 0.79. The lowest Cronbach's alpha coefficient was related to agreeableness factor AND the highest was related to conscientiousness. The findings from the multitrait-multimethod matrix showed that the BFI-29 questionnaire has good convergent AND divergent validity WITH the NEO-FFI questionnaire. In general, based on the results of the present study, it can be said that the BFI-29 questionnaire has desirable psychometric properties AND whenever a short tool for personality measurement is needed, this questionnaire can be used.

Purpose: Food security is a critical global challenge that is influenced by research AND innovation in the field. Therefore, the objective of this study is to analyze the scientific output of developing countries in food security AND examine its relationship WITH patents AND Gross Domestic Product (GDP).Methodology: This applied research utilized the Scientometric approach. A total of 8,416 papers published between 1992-2023 in the field of food security by developing countries were included in the study using citation databases from Clarivate Analytics. Additionally, patent registrations from the WIPO database AND GDP data from the World Bank were analyzed. Information was collected through note-taking, AND the data was analyzed using Pearson's correlation coefficient.Findings: The findings reveal an upward trend in the publication AND citation of scientific outputs related to food security in developing countries. China has higher numbers of papers, patents, GDP, AND food production index compared to Iran, Japan, AND South Korea. There is also a positive correlation observed between population AND the number of papers, gross production AND the number of papers, food production AND the number of published papers, as well as the number of patents AND papers citing scientific outputs of countries.Conclusion: These results highlight the significant relationship between increasing scientific output, GDP, the number of patents, AND food security. Greater emphasis on food security contributes to enhanced scientific output, GDP, AND innovation. Similarly, increasing scientific output, GDP, AND innovation positively impact food security in countries.Value: This study emphasizes the importance of scientific outputs in driving technological advancements, innovations, AND ultimately, ensuring food security in developing countries.

چکیده: 

The present research was conducted WITH the aim of the relationship between social factors AND family violence against children (child abuse). The used method was a survey AND the data collection tool was also a questionnaire. From a total of 155 families WITH a history of child abuse based on the social emergency statistics of Tehran in the last 6 months of 1397, 110 families (parents WITH one or more children) were selected in District 9 of Tehran Municipality. The rANDom sampling method was simple. In the present study, children under 11 years (6-11 years) were defined as the age RANGE of children AND family violence was also defined as violence applied by parents, older siblings. Research hypotheses were tested WITH SPSS statistical software through Pearson's correlation coefficient. The results showed that the experience of violence has a positive relationship WITH psychological violence, physical violence, neglect against children AND family violence against children. In other results, it was found that violence-oriented mentality has a positive relationship WITH psychological violence, physical violence, neglect against children AND family violence against children. In the continuation of the obtained results, the positive relationship of family problems WITH mental violence, physical violence AND neglect against children AND family violence against children was confirmed AND it was found that gender stereotypes have a positive relationship WITH mental violence, physical violence AND neglect against children AND family violence against children. Finally, in the main hypothesis, the results showed: social factors have a positive relationship WITH psychological violence, physical violence AND neglect against children AND family violence against children.

چکیده: 

The proposed idea in this article is initially to select the best seed layer in terms of spectral properties, AND then to place the next nanostructured layers of ZnO on it. If the UV-Visible spectrum of the seed layer is suitable AND desirable, the ZnO nanorod layer formed on it will have a better spectral quality. The result of this article shows that the formation of ZnO layer by layer AND the selection of the best layer which is obtained by the change in the precursors’ concentration lead to a ZnO thin layer WITH high absorption RANGE from in infrared to ultraviolet RANGE. In this way, ZnO nanostructures are selected step by step based on UV-Visible spectroscopic properties which were based on the difference in the concentration of precursors AND absorption value, AND threshold. The study of FESEM image of ZnO thin layer indicates the formation of diagonal nanorods, which have a coral-like appearance WITH high ratio of length to diameter. XRD studies confirm the growth of diagonal nanorods when concentration of precursors increases. These properties have a good match WITH high AND WIDE absorption in coral-like ZnO nanostructures.
